-Combination of the roll and the medicine packaging device-
As shown in FIG. 4, a core body 61 is attached to the outer periphery of the support shaft 31. When the core body 61 is mounted on the outer circumference of the support shaft 31, a part of the support shaft 31 projects from the core body 61. Specifically, the tip end portion of the support shaft 31 projects from the core body 61. A part of the support shaft tip body 31B projects from the core body 61. The support shaft 31 does not have to protrude from the core body 61 in a state where the core body 61 is attached to the outer periphery of the support shaft 31.

In the wound body 6, the packaging material 62 is wound around the outer periphery of the core body 61 as described above. Note that the packaging material 62 is omitted in FIG. In the present embodiment, the packaging material 62 is classified into two types regarding the sealing temperature. The packaging material 62 belonging to the first type is heat-sealed at the first sealing temperature. The packaging material 62 belonging to the second type is heat-sealed at a second sealing temperature different from the first sealing temperature.

In the present embodiment, one type of core body 61 can handle two types of packaging materials 62. In the present embodiment, the orientation of the core body 61 with respect to the packaging material 62 is selected according to the type of the packaging material 62. When the packaging material 62 belonging to the first type is wound, the orientation of the core body 61 with respect to the packaging material 62 is selected so that one end of the core body 61 is on the fold side of the packaging material 62. Hereinafter, the wound body 6 configured by winding the packaging material 62 belonging to the first type may be referred to as a first wound body 6. When the packaging material 62 belonging to the second type is wound, the orientation of the core body 61 with respect to the packaging material 62 is selected so that the other end of the core body 61 is on the fold side of the packaging material 62. .. Hereinafter, the wound body 6 configured by winding the packaging material 62 belonging to the second type may be referred to as a second wound body 6.

When the first winding body 6 is attached to the support shaft 31, the core body 61 is attached to the outer periphery of the support shaft 31 from one end side of the core body 61. In this case, each first protrusion 313 and each one end side first recess 6151 are fitted. As a result, the support shaft 31 and the core body 61 can integrally rotate in the circumferential direction of the support shaft 31.

The core body 61 can be attached to the support shaft 31 at at least one (a plurality of, specifically two in this embodiment) angular position. Specifically, the core body 61 is attached to the support shaft 31 at an angular position where the first one end side first concave portion 6151 and the first first protruding portion 313 coincide with each other. Alternatively, the core body 61 is attached to the support shaft 31 at an angular position where the first one end side first recessed portion 6151 and the third first protruding portion 313 coincide with each other.

In a state where the core body 61 is attached to the outer circumference of the support shaft 31, each first protrusion 313 is in contact with the end of each one end side first recess 6151, and each projecting/retracting portion 316 is The first hooking recesses 6152 are hooked on the stepped portions 615a of the respective first hooking recesses 6152. Therefore, the core 61 is prevented from being displaced in the axial direction of the support shaft 31 with respect to the outer periphery of the support shaft 31, and the core 61 is reliably attached to the outer periphery of the support shaft 31. Since each first protrusion 313 is in contact with the end of each one end-side first recess 6151, the core body 61 is prevented from being displaced with respect to the support shaft 31 in the mounting direction. Since each projecting/retracting portion 316 is hooked in each first hooking recessed portion 6152, the core body 61 is prevented from being displaced in the removal direction with respect to the support shaft 31.

When the second winding body 6 is mounted on the support shaft 31, the core body 61 is mounted on the outer periphery of the support shaft 31 from the other end side of the core body 61. In this case, each first protrusion 313 and each other end side first recess 6152 are fitted together. As a result, the support shaft 31 and the core body 61 can integrally rotate in the circumferential direction of the support shaft 31.

The core body 61 can be attached to the support shaft 31 at at least one (a plurality of, specifically two in this embodiment) angular position. Specifically, the core body 61 is mounted on the support shaft 31 at an angular position where the first other end side first concave portion 6152 and the first first protruding portion 313 coincide with each other. Alternatively, the core 61 is attached to the support shaft 31 at an angular position where the first other end side first concave portion 6152 and the third first protruding portion 313 coincide with each other.

In a state where the core 61 is attached to the outer circumference of the support shaft 31, each first protrusion 313 is in contact with the end of each other-end side first recess 6152, and each projecting/retracting portion 316 is Each second hooking recess 6151 is hooked on the stepped portion 615a of each second hooking recess 6151. Therefore, the core 61 is prevented from being displaced in the axial direction of the support shaft 31 with respect to the outer periphery of the support shaft 31, and the core 61 is reliably attached to the outer periphery of the support shaft 31. Since each first protrusion 313 is in contact with the end of each other-end-side first recess 6152, the core body 61 is prevented from being displaced in the mounting direction with respect to the support shaft 31. Since each projecting/retracting portion 316 is hooked in each second hooking recess 6151, the core body 61 is prevented from being displaced in the removal direction with respect to the support shaft 31.

The medicine packaging device 1 is configured to stop the operation when each moving unit 314 moves from the retracted position to the advanced position. The position of each moving unit 314 is detected by the sensor. The medicine packaging device 1 becomes operable or inoperable based on the detection result of the sensor.
The medicine packaging device 1 is operable when each moving unit 314 is in the retracted position. The medicine packaging device 1 is inoperable when the moving parts 314 are in the forward movement position.

When the winding body 6 is mounted on the support shaft 31, each moving portion 314 is pushed by the end surface formed by the packaging material 62 in the winding body 6. Therefore, each moving unit 314 is located at the retracted position. At this time, the medicine packaging device 1 is operable.

When all the packaging material 62 is unwound from the winding body 6, only the core body 61 remains on the support shaft 31. The end surface of the wound body 6 that is formed of the packaging material 62 disappears. Therefore, each moving portion 314 moves in the direction from the base end portion of the support shaft 31 toward the tip end portion of the support shaft 31. When the first winding body 6 is attached to the support shaft 31, each moving portion 314 enters each one end side notch portion 6111. When the second winding body 6 is attached to the support shaft 31, each moving portion 314 enters each other end side notch portion 6112. Thus, when each moving part 314 moves from the retracted position to the advanced position, the operation of the medicine packaging device 1 is stopped.

The medicine packaging device 1 is configured to detect magnetism on at least one of the base end side of the support shaft 31 and the tip end side of the support shaft 31 (both in this embodiment). The magnetic detection unit for detecting magnetism may be provided inside the support shaft 31 or may be provided outside the support shaft 31.

In such a medicine packaging device 1, at least one of the one end side magnets 6131 and the other end side magnets 6132 (both in the present embodiment) in a state where the winding body 6 is attached to the support shaft 31. To detect. When the first winding body 6 is mounted on the support shaft 31, the one end side magnets 6131 are detected on the base end side of the support shaft 31 and the other end parts are detected on the tip end side of the support shaft 31. The side magnet 6132 is detected. When the second winding body 6 is attached to the support shaft 31, the other end side magnets 6132 are detected on the base end side of the support shaft 31 and each end part is detected on the tip end side of the support shaft 31. The side magnet 6131 is detected. The medicine packaging device 1 sets the sealing temperature for heat-sealing the packaging material 62 based on the detection result. Therefore, the medicine packaging device 1 can heat seal the packaging material 62 at the sealing temperature according to the type of the packaging material 62.

-Installation of the winding body by the operator and removal of the core body-
Next, when the worker mounts the winding body 6 on the support shaft 31, and when the worker mounts the core body 61 remaining on the support shaft 31 after the packaging material 62 is completely unwound from the winding body 6, The case of removing from will be described.

As shown in FIG. 5, the support shaft 31 and the core body 61 are aligned with each other in the circumferential direction of the support shaft 31 when the core body 61 is mounted on the outer periphery of the support shaft 31. In FIG. 5, the second protrusion 317 and the third protrusion 317 are indicated by a chain double-dashed line. Note that, in FIG. 5, for ease of understanding, the second protrusion 317 of the support shaft 31 is shown to move in the axial direction of the core body 61 with respect to the core body 61. However, in reality, the opposite is true, and the core body 61 moves in the axial direction of the support shaft 31 with respect to the second protrusion 317 of the support shaft 31.

When the core body 61 is mounted on the outer periphery of the support shaft 31, the support shaft 31 does not move in the circumferential direction, and the core body 61 may rotate in the circumferential direction with respect to the support shaft 31, or The core body 61 may be immovable in the circumferential direction, and the support shaft 31 may rotate in the circumferential direction with respect to the core body 61. Alternatively, both the support shaft 31 and the core 61 may rotate in the circumferential direction.

Here, regarding the alignment of the support shaft 31 and the core body 61, a case where the first winding body 6 is mounted on the support shaft 31 will be described. When the second winding body 6 is attached to the support shaft 31, the second winding body 6 is basically different from the case where the first winding body 6 is attached to the support shaft 31, except for the orientation of the core body 61. Is the same. Therefore, description of the case where the second winding body 6 is mounted on the support shaft 31 is omitted.

When mounting the first winding body 6 on the support shaft 31, the operator first holds the first winding body 6 and attaches the first winding body 6 to the tip end portion of the support shaft 31. Place it in the previous position. The operator turns one end of the core body 61 toward the support shaft 31. The operator aligns the central axis of the core body 61 with the central axis of the support shaft 31. Then, the operator moves the first wound body 6 in the mounting direction with respect to the support shaft 31.

When the worker moves the first winding body 6 in the mounting direction with respect to the support shaft 31, one end portion of the core body 61 is extrapolated to the tip end portion of the support shaft 31. At the position of one end of the core 61, the second recess 616 is formed over the entire circumference of the core 61. Therefore, the operator does not need to intentionally align the support shaft 31 and the core body 61 with each other in the circumferential direction of the support shaft 31. Therefore, the work of mounting the winding body 6 on the support shaft 31 becomes easy.

The new winding body 6 in which the packaging material 62 is not consumed is heavy. It is difficult for an operator to align the support shaft 31 and the core body 61 in the circumferential direction of the support shaft 31 with the wound body 6 being lifted. Therefore, it is a great advantage for the operator that it is not necessary to intentionally align the support shaft 31 and the core body 61 in the circumferential direction of the support shaft 31.

While the worker moves the first wound body 6 in the mounting direction with respect to the support shaft 31, the projecting and retracting portions 316 come into contact with the inner peripheral surface portions 617. However, each projecting/retracting portion 316 is pushed inward in the radial direction of the support shaft 31 by each inner peripheral surface portion 617. Therefore, the worker can move the winding body 6 in the mounting direction with respect to the support shaft 31 without any trouble.

When the worker further moves the first wound body 6 in the mounting direction with respect to the support shaft 31, as shown in FIG. 5, each second protrusion 317 enters each one end side guiding portion 6162. To do. Specifically, the first second protrusion 317 enters the one end side guide portion 6162 of the first second recess 616, and the second second protrusion 317 causes the second second recess 616. The guide portion 6162 on the one end side thereof. Alternatively, the first second protrusion 317 enters the one end side guide portion 6162 of the second second recess 616, and the second second protrusion 317 causes the one end of the first second recess 616. Enter the side guiding part 6162. Which one of the one end side guide portions 6162 each second protrusion 317 enters is determined by the positional relationship between the support shaft 31 and the core body 61 in the circumferential direction of the support shaft 31 at that time.

When the worker further moves the first wound body 6 in the mounting direction with respect to the support shaft 31, as shown in FIG. 5, the second protrusions 317 are moved to the one-end-side guide portions 6162. Be induced. Each one end side guide part 6162 guides each second projection part 317 such that each first projection part 313 and each one end side first recess part 6151 are aligned in the circumferential direction of the support shaft 31. Therefore, the operator only has to move the winding body 6 with respect to the support shaft 31 in the mounting direction. The operator does not need to intentionally align the support shaft 31 and the core body 61 with each other in the circumferential direction of the support shaft 31. Therefore, the work of mounting the winding body 6 on the support shaft 31 becomes easy.

When the worker further moves the first wound body 6 in the mounting direction with respect to the support shaft 31, as shown in FIG. 5, each second protrusion 317 enters each guide portion 6161, It is guided by each guide unit 6161. Each guide portion 6161 guides each second protrusion 317 so that each first protrusion 313 and each one end side first recess 6151 are maintained in a state of being aligned in the circumferential direction of the support shaft 31. To do. Therefore, the operator only has to move the winding body 6 with respect to the support shaft 31 in the mounting direction. The operator does not need to intentionally maintain the state where the support shaft 31 and the core body 61 are aligned in the circumferential direction of the support shaft 31. Therefore, the work of mounting the winding body 6 on the support shaft 31 becomes easy.

When the worker further moves the first winding body 6 in the mounting direction with respect to the support shaft 31, the third protrusion part enters one of the guide parts 6161 to determine which one of the guide parts 6161. You will be guided to. When the first second protrusion 317 is guided by the first guide portion 6161, the third protrusion 318 is continuously guided by the first guide portion 6161. When the first second protrusion 317 is guided by the second guide portion 6161, the third protrusion 318 is continuously guided by the second guide portion 6161. The third protrusion 318 is provided in either one of the guide portions 6161 so that each first protrusion 313 and each one end-side first recess 6151 are maintained in a state of being aligned in the circumferential direction of the support shaft 31. Be guided to. Therefore, the operator only has to move the winding body 6 with respect to the support shaft 31 in the mounting direction. The operator does not need to intentionally position the support shaft 31 and the core body 61 in a state where they are aligned in the circumferential direction of the support shaft 31. Therefore, the work of mounting the winding body 6 on the support shaft 31 becomes easy.

When the worker further moves the first wound body 6 with respect to the support shaft 31 in the mounting direction, each first protrusion 313 enters each one end-side first recess 6151. When the third protruding portion 318 is guided by the first guide portion 6161, the first first protruding portion 313 enters the first one end side first recessed portion 6151 and the second first protrusion The part 313 enters the second one end side first recess 6151, the third first protrusion 313 enters the third one end side first recess 6151, and the fourth first protrusion 313. Enters the first recess 6151 on the fourth one end side. When the third protruding portion is guided by the second guide portion 6161, the first first protruding portion 313 enters the third one end side first recessed portion 6151, and the second first protruding portion 313 enters the fourth one end side first concave portion 6151, the third first protrusion 313 enters the first one end side first concave portion 6151, and the fourth first protrusion 313 , And enters the first recess 6151 on the second end side.

When the worker further moves the first winding body 6 in the mounting direction with respect to the support shaft 31, the end surface formed by the packaging material 62 in the first winding body 6 is located at the forward position. It abuts on each of the moving parts 314.

When the worker further moves the first winding body 6 in the mounting direction with respect to the support shaft 31, the first protrusions 313 and the first recesses 6151 on the one end side are fitted to each other. Each first protrusion 313 abuts on the end of each one end-side first recess 6151, and each projecting/retracting portion 316 disengages from the inner peripheral surface portion 617 and projects radially outward of the support shaft 31, 1 It catches on the hooking recess 6152. Each moving part 314 is pushed by the end surface formed by the packaging material 62 in the first winding body 6 and moved from the forward movement position to the backward movement position.

Thus, the mounting of the first winding body 6 on the support shaft 31 is completed. After that, the worker unwinds the packaging material 62 from the winding body 6 and sets the packaging material 62 in the packaging material conveying unit 4 and the packaging body forming unit 5.

When the packaging material 62 is completely unwound from the winding body 6 by the operation of the medicine packaging device 1, only the core body 61 remains on the support shaft 31. The operator removes the core body 61 from the support shaft 31. When removing the core body 61 from the support shaft 31, the operator holds the core body 61 and moves the core body 61 in the removal direction. At this time, each projecting/retracting portion 316 is caught in each first hooking recess 6152, but each projecting/retracting portion 316 is moved by the core body 61, and the diameter of the support shaft 31 is increased by the inner peripheral surface portion 617 of the core body 61. It is pushed inward. Therefore, the operator can move the core body 61 in the detaching direction with respect to the support shaft 31 without any trouble.

Although partially repeated, in the present embodiment as described above, the packaging material supply unit 3 includes the support shaft 31, as shown in FIG. 2. The support shaft 31 is provided so as to protrude from a base (not shown). A part of the packaging material conveying unit 4 (tension adjusting mechanism 41 shown in FIG. 1) is also provided on this base. The support shaft 31 has a substantially columnar shape. The support shaft 31 has a cylindrical outer peripheral portion. The support shaft 31 has a base end portion (left portion in the drawing) and a tip end portion (right portion in the drawing). The base end of the support shaft 31 is supported by the base. The support shaft 31 includes a main shaft portion 311 having a constant diameter dimension, and a base end shaft portion 312 located closer to the base end side than the main shaft portion 311 and having a larger diameter dimension than the main shaft portion 311. A step is formed between the main shaft portion 311 and the base end shaft portion 312 as shown in the figure.

The support shaft 31 is rotatably provided with respect to the base and supports the winding body 6 (core body 61). The support shaft 31 is driven and rotated by a drive unit such as a stepping motor (not shown) provided inside the base. The rotation of the support shaft 31 is performed in both the unwinding direction and the winding direction of the packaging material 62. In addition, the support shaft 31 is intermittently rotated in response to the supply of the packaging material 62 to the package forming portion 5. The support shaft 31 is cantilevered from the base, and the tip of the support shaft 31 is open. Therefore, as shown in FIG. 2, the core body 61 of the winding body 6 is arranged at the axially extended position on the open side of the support shaft 31, and is wound in the axial direction from the distal end side toward the proximal end side. By inserting the winding body 6, the winding body 6 (only the core body 61 is shown) can be attached to the support shaft 31 as shown in FIG. The winding body 6 is attached to the support shaft 31 so as not to rotate relatively.

The support shaft 31 of the present embodiment is formed to be longer in the axial direction than the winding body 6. For this reason, as shown in FIG. 4, a part of the support shaft 31 (support shaft tip body 31B) projects from the core body 61 in the mounted state (mounting state to the support shaft body 31A). However, the present invention is not limited to this, and the other end (described later) of the core 61 in the mounted state and the tip of the support shaft 31 may be aligned.

Further, a part of the support shaft 31 protruding from the core 61 on the tip side (a part where the guide projection 317 is formed) is a separate body from the support shaft main body 31A which is the base end side part of the support shaft 31. The support shaft tip body 31B is attached to the support shaft body 31A. This support shaft tip body 31B can be used in combination with the winding body 6 of the present embodiment. The attachment of the support shaft tip body 31B to the support shaft main body 31A is, for example, the diversion of the fitting structure for attaching the tip cover included in the support shaft included in the existing drug packaging device (after removing the tip cover, the support shaft is removed). It is performed by fitting by attaching the tip body 31B) or adhering to an existing support shaft (not limited to this, various mounting modes can be used). The support shaft main body 31A includes a cylindrical outer peripheral portion. The support shaft tip body 31B, which is mounted on the support shaft main body 31A, serves as a mounting auxiliary portion that is a part of the support shaft 31. This structure can be used as the support shaft 31 of the present embodiment, for example, by mounting the cover member provided at the tip of the short support shaft so as to be replaced. The support shaft tip body (mounting auxiliary portion) 31B attached to the tip end of the support shaft main body 31A enables the support shaft 31 of the present embodiment to be formed without significantly modifying the support shaft provided in the existing drug packaging device. Therefore, the combination of the wound body 6 and the medicine packaging device 1 of the present embodiment can be realized at low cost. However, for example, in the newly manufactured support shaft 31, the support shaft main body 31A and the support shaft tip body 31B may have an integral structure instead of such a separate structure. It should be noted that even a newly manufactured support shaft 31 can adopt a separate structure. For example, when disposing a magnetic detection unit or the like inside the support shaft 31, the inside can be opened as necessary, and thus the separate structure is useful.

As shown in FIG. 2, a plurality of (four in the present embodiment) hook protrusions 313 as first protrusions are formed on the base end shaft portion 312 of the support shaft 31. The plurality of hooking protrusions 313 to 313 are provided at regular intervals (at intervals) in the circumferential direction (rotational direction). Each hooking protrusion 313 projects radially outward from the outer peripheral surface of the base end portion of the support shaft 31. Each hooking protrusion 313 extends axially from the base end of the support shaft 31 by a predetermined distance in the distal direction. A part of the plurality of hooking protrusions 313 to 313 (in this embodiment, every other hooking protrusion 313 in the circumferential direction) is provided with a moving portion. In the present embodiment, as this moving portion, a rod-shaped packaging material shortage detection pin 314 projects in a radial direction from a part of the hooking protrusions 313 to 313. The tip of the packaging material breakage detection pin 314 is set to be positioned outside the outer peripheral surface of the core body 61 when the winding body 6 is mounted on the support shaft 31. Further, the hooking protrusion 313 provided with the packaging material breakage detection pin 314 is provided with a cutout portion 315 that penetrates in the radial direction and extends in the axial direction.

The packaging material shortage detection pin 314 is urged toward the tip end side (right side in the drawing) in the axial direction of the support shaft 31 by the urging force of a spring (not shown) provided inside the support shaft 31. When the wound body 6 in which the packaging material 62 is wound is attached to the support shaft 31, the packaging material shortage detection pin 314 is located closer to the packaging material 62 that is radially laminated on the outer periphery of the core body 61. By being pushed out toward one side, it is moved toward the axial base end side against the spring bias. In addition, in the core body 61 of the wound body 6, a notch that penetrates in the radial direction and extends in the axial direction, as in the case of the support shaft 31, in a portion that corresponds to the packaging material cutout detection pin 314 when mounted on the support shaft 31. A section 611 is provided. The notch portion 611 includes one end side notch portion 6111 provided at one end portion side of the core body 61 and the other end side notch portion 6112 provided at the other end portion side of the core body 61. The one end side notch 6111 is provided at the same position as the one end side hooking recessed portion 6151 in the circumferential direction of the core body 61, and extends from the end surface of the one end portion of the core body 61 toward the other end portion of the core body 61. It has a notched shape. The other end side notch 6112 is provided at the same position as the other end side hooking recess 6152 in the circumferential direction of the core 61, and extends from the end face of the other end of the core 61 toward one end of the core. It has a notched shape. When the notch 611 is located at the base end of the support shaft 31, the packaging material breakage detection pin 314 can enter.

The notch 611 is arranged so as to match the notch 315 of the support shaft 31 in the circumferential direction. Therefore, the core body 61 may be rotated in the circumferential direction with respect to the support shaft 31 by an operator for the purpose of aligning the cutout portion 611 (this point will be described later). When the packaging material 62 is pulled out from the wound body 6 and disappears (that is, when only the core body 61 is used), the pushing-out by the packaging material 62 is stopped, so that the spring-energized packaging material cutout detection pin 314 is removed. It moves to the tip end side in the axial direction and enters the notch 611 (see FIG. 4 ). In this way, by detecting that the packaging material shortage detection pin 314 has entered the notch 611 with a sensor or the like, the packaging material shortage can be detected. By detecting that the packaging material 62 is completely unwound from the winding body 6, for example, the operation of the medicine packaging device 1 is stopped. Specifically, the packaging material supply unit 3 can be automatically stopped.

A projecting/retracting portion 316 projects from the outer peripheral portion (specifically, the outer peripheral surface) of the support shaft 31. At least one projecting/retracting portion 316 (not shown in the figure, but two in this embodiment) is provided. When a plurality of projecting/retracting portions 316 are provided as in the present embodiment, the plurality of projecting/retracting portions 316 are provided at a constant distance (spaced) in the circumferential direction. In the present embodiment, the two projecting/retracting portions 316 are located at equal intervals in the circumferential direction (that is, at angular intervals of 180 degrees). Further, in the present embodiment, each projecting/retracting portion 316 is provided at the same position as any of the plurality of (four in the present embodiment) hooking protrusions 313 to 313 at the circumferential position. Each projecting/retracting portion 316 of the present embodiment is provided at the same position in the circumferential direction as the catching protrusion 313 having the packaging material out-of-process detection pin 314 and the cutout portion 315. Further, each projecting/retracting portion 316 is provided at a position different from each guide protrusion 317 and sub guide protrusion 318 in the circumferential direction. In this embodiment, they are provided at an angle of 90 degrees. The projecting/retracting portion 316 is, for example, a spherical shape or a hemispherical shape, and is a protrusion that is biased radially outward by a spring provided inside the support shaft 31 and partly projects from the outer peripheral surface of the support shaft 31. The projecting/retracting portion 316 is provided on the outer peripheral surface of the support shaft 31 so as to project and retract.

The projecting/retracting portion 316 is formed on the inner peripheral portion of the core 61 so as to be recessed radially outward (in the present embodiment, the other end side engaging recess 6152 as the first engaging recess and the first engaging recess 6152). (2) Hooking concave portion 6151 as one hooking concave portion), the stepped portion 615a (see FIG. 3), which is located on the tip side of the support shaft 31, is engaged. When the core body 61 is attached to the support shaft 31 from the one end side, the other end side hooking recessed portion 6152 is hooked by the spring-biased projecting/retracting portion 316. When the core body 61 is attached to the support shaft 31 from the other end side, the one end side hooking concave portion 6151 is hooked by the spring-biased projecting/retracting portion 316. For this reason, when the core body 61 is mounted on the outer periphery of the support shaft 31, the projecting/retracting portion 316 is caught in the hooking recess 615, so that the core body 61 moves relative to the support shaft 31 at the base end portion of the support shaft 31. The deviation from the direction toward the tip is prevented. Therefore, the winding body 6 can be reliably attached to the support shaft 31. On the other hand, since the projecting/retracting portion 316 is biased by the spring, for example, when the core body 61 is removed from the support shaft 31, if the core body 61 is moved in the axial direction by a force that overcomes the biasing force of this spring, 61 moves with respect to the support shaft 31. Therefore, when the core body 61 is pulled out from the support shaft 31, the work can be performed without any trouble. By the way, during the mounting of the core body 61 on the support shaft 31, before the protruding/retracting portion 316 engages with the step portion 615a, the protruding/retracting portion 316 is in contact with the inner peripheral surface portion 617 of the core body 61. At this time, since the projecting/retracting portion 316 is pushed by the inner peripheral surface portion 617, it is moving in the radial inward direction.

At least one (two in the present embodiment) guide projection 317 as a second projection is formed at the tip of the support shaft 31 (main shaft 311). When a plurality of guide protrusions 317 are formed, the plurality of guide protrusions 317 to 317 are provided at a constant distance (spaced) in the circumferential direction. In this embodiment, the angle is 180 degrees apart. Each of the guide projections 317 projects radially outward from the outer peripheral surface of the tip end portion of the support shaft 31. Each guide protrusion 317 projects at the same position as a part (two in four in this embodiment) of the plurality of hooking protrusions 313 to 313 in the circumferential direction. Specifically, the packaging material out detection pin 314 and the hooking protrusion 313 having no notch 315 project at the same position in the circumferential direction. Further, each guide protrusion 317 has a smaller amount of protrusion outward in the radial direction with respect to the outer peripheral portion of the support shaft body 31A than each hook protrusion 313.

As shown in FIG. 2, the guide protrusion 317 includes a main body portion 3171 having a constant width and a tapered portion 3172 which is provided on the distal end side of the main body portion 3171 and whose width dimension is reduced toward the distal end. Prepare for one. The tapered portion 3172 has an inclined surface at the end in the width direction. In the present embodiment, the inclined surface is formed in a linear shape as viewed in the radial direction, but the present invention is not limited to this, and may be another shape such as a curved linear shape. Further, although the slope is symmetrical with respect to the axial direction in the present embodiment, it may be asymmetric.

A sub-guide protrusion 318 as a third protrusion, which is an outer peripheral portion of the support shaft 31 and is located at an intermediate position between the base end portion and the tip end portion of the support shaft 31, and which projects outward in the radial direction, is formed. There is. At least one sub-guide projection 318 (one in the present embodiment) is formed on the main shaft portion 311 and is continuous to the proximal end side of the guide projection 317. As described above, since two guide protrusions 317 are formed in this embodiment, one of the guide protrusions 317 (the guide protrusion 317 appearing in FIG. 2) extends axially on the proximal end side. The auxiliary guide protrusions 318 are arranged on the line. A hooking protrusion 313 is located on the base end side of the auxiliary guide protrusion 318.

The sub-guide projection 318 is provided at the same position as the guide projection 317 in the circumferential direction around the central axis, and the amount of projection of the support shaft 31 outward in the radial direction with respect to the outer peripheral portion of the support shaft 31 is the same as that of the guide projection 317. It is the same. The sub-guide projection 318 maintains the state in which the hooking projection 313 and the hooking recess 615 are aligned in the circumferential direction around the central axis when the core body 61 is mounted on the outer circumference of the support shaft 31. , And is guided by the guide portion 6161.

With the insertion of the core body 61 into the support shaft 31, the inner peripheral surface portion 617 of the core body 61 comes into contact with the guide protrusions 317, so that the core body 61 is aligned in the circumferential direction with respect to the support shaft 31. It can be performed (positioning of the core body 61 will be described later). This is shown in FIG. Incidentally, in order to facilitate understanding in FIG. 5, the guide protrusion 317 (two-dot chain line) is shown to move in the axial direction with respect to the core body 61, but actually it is the reverse of the illustration. The core body 61 moves in the axial direction with respect to the guide protrusion 317. At this time, the support shaft 31 and the core body 61 relatively rotate in the circumferential direction and are aligned. In the present embodiment, when the core body 61 is inserted into the support shaft 31 and the inner peripheral surface portion 617 of the core body 61 does not come into contact with the guide protrusion 317, the sub guide protrusion 318 continues to be inserted. By contacting the circumferential edge of the inner peripheral surface portion 617 of the core body 61, the circumferential alignment of the core body 61 with respect to the support shaft 31 can be continued. Therefore, stable positioning is possible during insertion of the core body 61. At the time of alignment, the support shaft 31 does not move in the circumferential direction, and the core body 61 may rotate in the circumferential direction with respect to the support shaft 31, or the core body 61 does not move in the circumferential direction. The support shaft 31 may rotate in the circumferential direction with respect to the core body 61. Both the support shaft 31 and the core 61 may rotate in the circumferential direction.

As shown in FIG. 2, the core body 61 of the wound body 6 has a tubular shape (cylindrical shape) or a tubular shape (circular tubular shape) having a circular radial cross section. The core 61 has a cylindrical inner peripheral portion. As shown in FIG. 1, the packaging material 62 is wound around the outer peripheral surface of the core body 61. The outer diameter dimension of the core body 61 is constant in the axial direction. Therefore, no step appears on the outer peripheral surface of the core body 61, so that the packaging material 62 can be wound without making a crease. The core body 61 is axially moved with respect to the outer periphery of the support shaft 31 in the packaging material supply unit 3 to be attached/detached (mounted and removed). The core body 61 is aligned in the circumferential direction of the support shaft 31 and mounted on the outer periphery of the support shaft 31. The core body 61 has one end and the other end. The one end is a portion near the support shaft 31 (left rear portion) in FIG. 2, and the other end is a portion far from the support shaft 31 (right front portion) in FIG. However, the core body 61 of the present embodiment has the same shape at one end and the other end except for the plurality of magnet holding portions 614 to 614, and has a symmetrical shape with respect to the axial center. There is. With the symmetrical shape, the core body 61 can be attached to the support shaft 31 from one end side or the other end side. Therefore, the permanent magnets (magnets 613 to 613) attached to the plurality of magnet holding portions 614 to 614 can distinguish which one of the one end and the other end is to be attached to the support shaft 31. One core body 61 having the same shape can correspond to at least two types of packaging materials 62. Therefore, management when manufacturing the wound body 6 is easy.

The core body 61 is attached to the support shaft 31 from one end side and is attached to the support shaft 31 from one end side according to the type of the packaging material 62 to be wound, as a regular orientation (attachment direction). May be done. At the time of mounting, the core body 61 is moved in the axial direction from the front end portion to the base end portion of the support shaft 31. The core body 61 is provided with notches 611 at both ends. The cutout portion 611 is provided at a position corresponding to the packaging material cutout detection pin 314 that projects radially outward from the support shaft 31 when the core body 61 is mounted on the support shaft 31. The cutout portion 611 has a space that penetrates the core body 61 in the radial direction and is open to an end surface of the core body 61. In this space, the packaging material breakage detection pin 314 can move in the axial direction of the support shaft 31. This movement is performed after the packaging material 62 is pulled out from the winding body 6 and is lost (FIG. 4 shows a state after the movement).

The core body 61 has a plurality of magnets that hold a combination of permanent magnets (magnets 613 to 613) corresponding to a magnetic detection unit such as a magnetic sensor that the packaging material supply unit 3 has for identifying the wound body 6. Holding units 614 to 614 are provided. In the present embodiment, the two magnet holding portions 614 and 614 are provided at one end of the core body 61 with an interval of 90 degrees in the circumferential direction. Then, at the other end of the core 61, two magnet holding portions 614 and 614 are provided 180 degrees apart in the circumferential direction. As described above, in the present embodiment, the position where the magnet holding portion 614 is provided differs between the one end portion and the other end portion. Therefore, when the permanent magnets (magnets 613 to 613) are arranged in all of the plurality of magnet holding portions 614 to 614, the positional relationship of the permanent magnets (magnets 613 to 613) arranged at the respective end portions becomes different.

Permanent magnets (magnets 613 to 613) may be arranged in a predetermined number of selected magnet holders 614 to 614 among the plurality of magnet holders 614 to 614. The "identification of the wound body 6" specifically means identifying the material of the packaging material 62, which is related to the sealing temperature at which the packaging material 62 is appropriately bonded when the packaging material 62 is bonded by heat sealing. Is. In the plurality of magnet holding units 614 to 614, the magnetic detection unit determines the number of magnet holding units 614 in which the permanent magnets (magnets 613 to 613) are arranged, the polarity of the permanent magnets (magnets 613 to 613), the strength of magnetic force, and the like. You may detect and identify. It should be noted that the medicine package configured to identify the wound body 6 by means other than magnetism, such as electromagnetic detection by an RFID tag capable of wireless identification such as an IC chip and optical detection by a two-dimensional code. The magnet holding unit 614 is not necessary in the device or the medicine packaging device in which the magnetic detection unit is removed or invalidated by modification. In the configuration for performing the electromagnetic detection, for example, an RFID tag or the like is arranged in the inner space of the core body 61. An RFID tag or the like may be arranged on the inner peripheral surface or the outer peripheral surface of the core body 61.

A plurality of one end side magnets 6131 are provided at one end of the core body 61 in the first positional relationship in the circumferential direction of the core body 61. On the other hand, at the other end of the core 61, a plurality of other end side magnets 6132 are provided in the circumferential direction of the core 61 in a second positional relationship different from the first positional relationship. The medicine packaging device 1 detects at least one of the plurality of one end side magnets 6131 and the plurality of other end side magnets 6132 by the magnetic detection unit in a state where the core body 61 is mounted on the outer periphery of the support shaft 31. The sealing temperature when heat-sealing the packaging material 62 is set.

The core body 61 includes a hooking recess 615 as a first recess, a guide recess 616 as a second recess, and an inner peripheral surface portion 617 on the inner periphery. A plurality of sets of the hook recess 615, the guide recess 616, and the inner peripheral surface 617 are provided in the circumferential direction. These can be provided at equal intervals in the circumferential direction. In the present embodiment, four sets of hook recesses 615 are provided at equal intervals in the circumferential direction, and two sets of guide recesses 616 and the inner peripheral surface portion 617 are provided at equal intervals in the circumferential direction. However, it is possible to provide only one set or a plurality of sets at unequal intervals. Further, these portions 615 to 617 are provided symmetrically in the axial direction (with reference to the center in the axial direction), as shown in FIGS. 2 and 3.

The hooking recess 615 is provided on the inner circumference on the one end side of the core body 61 and on the one end side hooking recess 6151 as the one end side first recess and the inner circumference on the other end side of the core body 61. The other end side hook recess 6152 is formed as the other end side first recess. A portion of the hooking concave portion 615 located on the base end side in a state of being attached to the support shaft 31 is fitted to a hooking protrusion 313 provided on the support shaft 31 to thereby rotate in a circumferential direction with the support shaft 31. To convey. That is, when the core body 61 is mounted on the outer periphery of the support shaft body 31A, the hooking protrusion 313 and the hooking recess 615 are fitted to each other, so that the support shaft body 31A and the core body 61 are connected to each other. It is possible to rotate integrally around the central axis of the outer peripheral portion of the. The number of hooking recesses 615 corresponds to the number of hooking protrusions 313 on the support shaft 31. The number of sets of the guide concave portion 616 and the inner peripheral surface portion 617 is equal to the number of the guide protrusions 317 on the support shaft 31. However, the number of hooking recesses 615 can be larger than the number of hooking protrusions 313 on the support shaft 31. Further, the number of sets of the guide concave portion 616 and the inner peripheral surface portion 617 can be larger than the number of the guide protrusions 317 on the support shaft 31.

The guide recess 616 is provided on the inner circumference of the core 61 along the axial direction. The guide recess 616 has an inner diameter larger than the outer diameter of the support shaft 31. The guide recess 616 has an inner peripheral portion (more specifically, an inner peripheral surface, more specifically, an inner peripheral surface) of the core body 61, as compared with the hooking recess 615 (the one end side hooking recess 6151 and the other end side hooking recess 6152). The amount of dents outward in the radial direction with respect to the surface portion 617 or the inner peripheral surface of the thick portion 619) is small. Therefore, it is possible to prevent the strength of the core body 61 from decreasing due to the depression. The guide recess 616 is formed over the entire circumference in the circumferential direction of the core 61 at the positions of one end and the other end of the core 61 (portions 6162a, 6163a shown in FIG. 3). For this reason, when the core body 61 is extrapolated to the support shaft tip body 31B, it is not necessary to align the support shaft tip body 31B and the core body 61 around the central axis line, and the work can be facilitated. .. When the core body 61 is mounted on the support shaft 31, the guide recess 616 engages with the guide protrusion 317 and the sub guide protrusion 318 to perform circumferential positioning with respect to the support shaft 31. That is, when the core body 61 is mounted on the outer periphery of the support shaft main body 31A, the guide projection 317 and the sub guide projection 318 and the guide recess 616 engage with each other, so that the guide projection 317 and the sub guide The projection 318 and the guide recess 616 are aligned in the circumferential direction around the central axis of the outer peripheral portion of the support shaft body 31A. The guide recess 616 is located at the center in the axial direction and is continuous with the positioning portion 6161 having a constant width dimension (circumferential dimension) and extending in the axial direction and one end side or the other end side of the positioning portion 6161. And a guide portion that extends in the axial direction and that has a width dimension (circumferential dimension) that increases from the center in the axial direction toward the one end side or the other end side. The guide portion includes one end side guide portion 6162 provided at a position near one end of the core body 61 and another end side guide portion 6163 provided at a position near the other end portion of the core body 61. .. The width dimension of the positioning portion 6161 is substantially the same as the width dimension of the guide protrusion 317. Specifically, it is larger (slightly larger) than the width dimension of the guide protrusion 317 so that the movement of the core body 61 in the axial direction with respect to the guide protrusion 317 can be allowed.

Since the circumferential dimension of each of the guide portions 6162 and 6163 decreases from the one end side or the other end side toward the center in the axial direction, the core body 61 can be moved in the circumferential direction according to these reductions ( Refer to FIG. 5 regarding the one end side guide portion 6162, but FIG. 5 shows the movement and immovability of the core body 61 and the guide protrusion 317 in the opposite manner to the actual state. Then, the hooking recess 615 of the core body 61 is aligned with the hooking protrusion 313 of the support shaft 31. In this way, the core body 61 rotates with respect to the support shaft 31 and is aligned in the circumferential direction.

As described above, each of the guide portions 6162 and 6163 is centered on the hooking protrusion 313 and the one end side hooking concave portion 6151 or the other end side hooking concave portion 6152 when the core body 61 is mounted on the outer periphery of the support shaft 31. The guide protrusion 317 is guided so that the guide protrusion 317 is aligned in the circumferential direction around the axis (in reverse view, the guide portions 6162 and 6163 are guided by the guide protrusion 317).

In the inner peripheral portion of the core body 61, the portions 6162a and 6163a (see FIG. 3) corresponding to the positions of the one end portion of the core body 61 and the other end portion of the core body 61 (see FIG. 3) are referred to as the guide protrusion 317. The action of moving the core body 61 in the circumferential direction due to the contact of is not exerted. The respective portions 6162a and 6163a act to facilitate the attachment of the core body 61 to the support shaft 31. That is, the inner diameter of each of the portions 6162a and 6163a is larger than the outer diameter of the support shaft 31. That is, the inner diameters of the respective portions 6162a and 6163a are in a loose relation with the outer diameter of the support shaft 31. Therefore, the winding body 6 (core body 61) can be easily inserted into the support shaft 31 as compared with a configuration in which there is no dimensional allowance. Incidentally, since the winding body 6 in which the packaging material 62 is wound around the core body 61 is heavy (especially, the new winding body 6 is particularly heavy because the packaging material 62 is not consumed at all). The ease is a great advantage for the user of the medicine packaging device 1. Incidentally, this action is also the action of the thin portion 618 described later.

Here, each of the portions 6162a and 6163a can also be said to be a “free area” that allows rotation of the core body 61 without restriction. Further, the positioning portion 6161 prevents the rotation of the core 61 substantially (specifically, the guide recess 616 of the core 61 with respect to the guide protrusion 317 and the sub guide protrusion 318 of the support shaft 31). (There is only a play in the circumferential direction to the extent that A is shifted in the axial direction). Further, it can be said that each of the guide portions 6162 and 6163 is a “transition region” in which the rotatable range of the core 61 is smaller on the axial center side than on the axial one end side and the other end side. The guide recess 616 extends from one end in the axial direction toward the center in the axial direction and is continuous in the order of the free region, the transition region, and the restricted region. Further, it extends from the center in the axial direction to the other end side in the axial direction and is further continuous with the transition region and the free region.

The inner peripheral surface portion 617 is a portion that is adjacent to the guide recess 616 in the circumferential direction. The inner peripheral surface portion 617 is thicker (having a larger radial dimension) than the guide recess 616. The inner peripheral surface portion 617 is provided at the center of the core body 61 in the axial direction, does not reach the end edges of the core body 61 on both axial side ends, and the tip is located between the axial center and the end edges on both axial side ends. To do. The tip portion of the inner peripheral surface portion 617 has a shape corresponding to the shape of each of the guide portions 6162 and 6163, the circumferential dimension increases from the one end side toward the axial center, and the axial center portion to the other end portion. The circumferential dimension is reduced toward the side. The shape of the inner peripheral surface portion 617 is symmetrical with respect to the center in the axial direction in the axial direction.

The surface of the inner peripheral surface portion 617 is a curved surface that curves in the circumferential direction with a constant curvature. The circumferential curvature of the surface of the inner peripheral surface portion 617 is the same (substantially the same) as the circumferential curvature of the outer peripheral surface of the support shaft 31. Since the surface of the inner peripheral surface portion 617 is a curved surface having a spread, the inner peripheral surface portion 617 makes surface contact with the outer peripheral surface of the support shaft 31 when the core body 61 is mounted. Here, for example, in a configuration in which a plurality of protrusions extending in the axial direction are formed on the inner peripheral surface of the core body, the linear contact is made with the outer peripheral surface of the support shaft. Here, a phenomenon called "winding tightness" may occur due to the stress (force to shrink in the longitudinal direction) remaining in the packaging material after winding and the surrounding temperature or humidity during the manufacture of the wound body. Due to this “winding tightness”, there is a possibility that deformation (distortion) will occur in the main body of the core body that is in a state of floating with respect to the support shaft. On the other hand, in the present embodiment, the surface of the inner peripheral surface portion 617 is in surface contact with the outer peripheral surface of the support shaft 31, so that it is possible to reduce the possibility that the above-described deformation (distortion) occurs in the core body 61.

Since the inner peripheral surface portion 617 is thick and the guide concave portion 616 is thin, a step is formed between the inner peripheral surface portion 617 and the guide concave portion 616. That is, the circumferential end edges of the positioning portion 6161 of the guide recess 616 and the guiding portions 6162 and 6163 are defined by the inner peripheral surface portion 617. The inner peripheral surface portion 617 has a core side slant surface 6171 that defines the width direction (circumferential direction) end edges of the guide portions 6162 and 6163 of the guide recess 616 (see FIG. 3 ).

When the core 61 having the hooking recess 615, the guide recess 616, and the inner peripheral surface 617 is to be mounted on the support shaft 31 from one end side, first, the core 61 is attached to the guide protrusion 317 of the support shaft 31. The guide part 6162 of is located. When the core body 61 is further moved in the axial direction, it changes so that the positioning portion 6161 of the core body 61 is positioned with respect to the guide protrusion 317 (see the position change indicated by the arrow in FIG. 5).

The positioning portion 6161 is also a guide portion that guides the guide protrusion 317. The positioning portion 6161 as the guide portion is provided at the center position in the axial direction of the core body 61, that is, between the one end side guide portion 6162 and the other end side guide portion 6163, and the guide portions 6162 and 6163 are provided. When the core 61 is attached to the outer periphery of the support shaft body 31A, the hooking protrusion 313 and the hooking recess 615 (the one end side hooking recess 6151 or the other end side hooking recess 6152) are connected to the outer circumference of the support shaft body 31A. The guide protrusion 317 is guided so that the state of being aligned in the circumferential direction around the central axis of the portion is maintained. According to this, when the core body 61 is attached to the support shaft body 31A, it is not necessary to intentionally maintain the state in which the support shaft body 31A and the core body 61 are aligned about the central axis. The work can be facilitated.

In addition, the one end side guide portion 6162 has a width dimension (circumferential dimension) reduced from one end portion to an axial center portion as it goes in a direction from one end portion to the other end of the core body 61. When the core body 61 is mounted on the outer periphery of the shaft body 31A, the guide protrusions 313 and the hook recesses 615 are aligned in the circumferential direction around the central axis of the outer peripheral portion of the support shaft body 31A. Induce 317. According to this, when the core body 61 is attached to the support shaft main body 31A, it is not necessary to intentionally align the support shaft main body 31A and the core body 61 around the central axis line, which facilitates the work. it can. The auxiliary guide protrusion 318 guides the core body 61 from the central portion to the other end portion in the axial direction as the core body 61 moves from one end to the other end.

Here, when the guide protrusion 317 is located at the circumferential end of the one end side guiding part 6162, the edge of the one end side guiding part 6162, that is, the core side slant surface 6171 on the one end side is the guide protrusion 317. Abut. As a result, the positioning portion 6161 of the core body 61 is guided so as to coincide with the guide protrusion 317. Then, when the core body 61 is further moved in the axial direction, the guide protrusion 317 comes off from the positioning portion 6161 of the core body 61. Then, instead of the guide protrusion 317, the positioning portion 6161 is guided so as to match the sub guide protrusion 318 formed continuously on the proximal end side of the guide protrusion 317 (see FIG. 5 ). As a result of the guidance by the guide protrusion 317 and the auxiliary guide protrusion 318, the hook protrusion 313 and the hook recess 615 are fitted together. When the core body 61 is further moved in the axial direction, a part of the guide projection 317 is projected from the other end portion of the core body 61, the hooking projection 313 and the hooking recess 615 are completely fitted, and finally, as shown in FIG. The state becomes as shown in.

The end edge of the one-side guide portion 6162 (the core-side inclined surface 6171) may come into contact with the inclined surface of the tapered portion 3172 of the guide projection 317 (see FIG. 5 ). Here, the slopes in the axial direction of the core side slanting surface 6171 that is the end edge of the one end side guiding portion 6162 and the slanting surface of the tapered portion 3172 of the guide projection 317 are substantially the same. Therefore, the contact is made smoothly. The other end side guide part 6163 is also the same.

According to the core body 61 of the present embodiment, the guide recess 616 facilitates attachment to the support shaft 31, and the inner peripheral surface portion 617 ensures the strength of the core body 61.

Further, the core body 61 includes a thin portion 618 and a thick portion 619. The thin portion 618 is provided on the inner circumference on the one end side and the other end side in the axial direction. Further, the thin portion 618 is fitted to the base end shaft portion 312 of the support shaft 31 in a state where the core body 61 is attached to the support shaft 31. The thick portion 619 is fitted to the main shaft portion 311 of the support shaft 31 in a state of being attached to the support shaft 31. The thick portion 619 is thicker than the thin portion 618. The thin portion 618 corresponds to the guide recess 616, and the thick portion 619 corresponds to the inner peripheral surface portion 617. The thin portion 618 has a purpose different from that of the guide recess 616 described above, but the forming range of the inner periphery of the core 61 is the same as that of the guide recess 616. The thin-walled portion 618 and the guide recess 616 can be formed in different ranges. The thick portion 619 has a purpose different from that of the inner peripheral surface portion 617 described above, but the forming range of the core body 61 is the same as that of the inner peripheral surface portion 617 described above. The thick-walled portion 619 and the inner peripheral surface portion 617 can be formed in different ranges.

-Reuse of used core-
The core 61 can be reused many times by reusing it after the packaging material 62 is used up. This can contribute to resource savings, for example. Reuse is performed by winding a new packaging material 62 around the used core body 61 collected from the user of the medicine packaging device 1. By winding the new packaging material 62 around the core body 61 to be reused, the new winding body 6 is manufactured. In order to facilitate recovery, the core body 61 of the wound body 6 delivered to the user is lent to the core body 61 so that the user returns the core body 61. Can be promoted.

For winding the new packaging material 62 around the used core body 61, for example, the new packaging material 62 is formed on a separate core body (paper tube or the like) 63 having an inner diameter dimension larger than the outer diameter dimension of the core body 61. Alternatively, a pre-fabricated packaging material roll (replacement winding body) may be attached to the used core body 61 by winding (FIG. 19). When this method is adopted, by interposing a spacer such as a rubber ring between the used core body 61 and the separate core body, the outer diameter dimension of the core body 61 and the inner diameter dimension of the separate core body are You can also adjust the difference.

The new wound body 6 may be manufactured by a supplier of the wound body 6, or the user of the wound body 6 may instruct the user to perform the manufacturing-related work. Can also In the latter case, the used core 61 is not collected but kept in the user's hand. The instructions from the supplier of the winding body 6 to the user may be explicit or implicit. The latter implied instructions also include the act of simply transferring the replacement winding to the user.

-Possibility of changing the form-
Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications can be made without departing from the scope of the present invention.

The support shaft 31 may have a form as shown in FIGS. 6 and 7, for example. The support shaft 31 shown in FIG. 6 and FIG. 7 is basically the same as the support shaft 31 of the above-described embodiment, but the third embodiment (the auxiliary guide protrusion) 318 is not provided in the above-described embodiment. The support shaft 31 of FIG. That is, the support shaft 31 may not be provided with the third protrusion 318.

The support shaft 31 in this form is, for example, a modification of the support shaft included in the existing drug packaging device. The support shaft included in the existing drug packaging device includes a support shaft main body 31A and a tip lid. The tip cover is attached to the tip of the support shaft body 31A and closes the tip of the support shaft body 31A. The support shaft 31 shown in FIGS. 6 and 7 has a support shaft main body 31A with a distal end lid removed from the support shaft main body 31A, and a support shaft distal end body (attachment aid) 31B attached to the front end portion of the support shaft main body 31A. Is. Such a support shaft 31 can be realized without significantly modifying the support shaft included in the existing medicine packaging device. Therefore, the combination of the wound body 6 of the present embodiment and the medicine packaging device 1 can be realized at low cost.

Further, the core body 61 may have a form such as a modified example shown in FIGS. That is, at least one (here, one) third recess 6172 may be further formed on the inner peripheral portion of the core body 61. The third recess 6172 engages with the projecting/retracting portion 316 of the support shaft 31 when the core body 61 is mounted on the outer periphery of the support shaft 31. The third recess 6172 is provided at an intermediate position between one end of the core 61 and the other end of the core 61, and is recessed radially outward. The third concave portion 6172 has a radial direction with respect to the inner peripheral portion of the core body 61 (specifically, the inner peripheral surface of the core body 61) in comparison with the first concave portion 6151 on the one end side and the first concave portion 6152 on the other end side. The amount of dents outward is small. Therefore, it is possible to prevent a decrease in strength of the core body 61 due to the formation of the third recess 6172.

The third recess 6172 is provided at a predetermined angular position in the circumferential direction of the core 61. In the present embodiment, the third recess 6172 is provided at an angular position deviated by 90° with respect to one second recess 616 of the two second recesses 616 in the circumferential direction of the core body 61. There is.
When the core body 61 is viewed from one end side, in the circumferential direction of the core body 61, assuming that the angular position of the first one end side first recessed portion 6151 is 0°, the angular position of the third recessed portion 6172 is 270°.

Such a third concave portion 6172 has a structure in which the first protrusion 313 and the first concave portions 615 (specifically, the above-mentioned, when the worker moves the wound body with respect to the support shaft 31 in the mounting direction). The projecting/retracting portion 316 is guided so that the one end side first recessed portion 6151 or the other end side first recessed portion 6152) is maintained in the state of being aligned in the circumferential direction of the support shaft 31. Therefore, even if the support shaft 31 is not provided with the above-described third protrusion 318, the operator only has to move the winding body 6 with respect to the support shaft 31 in the mounting direction. The operator does not need to intentionally position the support shaft 31 and the core body 61 in a state where they are aligned in the circumferential direction of the support shaft 31. Therefore, the work of mounting the winding body on the support shaft 31 becomes easy.

The shape of the portion of the core body 61 according to this modification closer to the center in the axial direction is not limited to the shapes shown in FIGS. 8 to 18, but may be various shapes. Further, the magnet holding portion 614 may be omitted. Further, although the inner peripheral surface portion 617 is provided at two places as described above, the shape of the inner peripheral surface portion 617 on which the third recess 6172 is not provided may be various shapes.

The magnet 613 may not be provided in the core body 61 regardless of the presence or absence of the magnet holding portion 614. In this case, the medicine packaging device 1 may set the sealing temperature by using another means. Further, in this case, the orientation of the core body 61 with respect to the packaging material 62 may be either direction. Either one of the one end of the core body 61 and the other end of the core body 61 may be on the fold side of the packaging material 62. In this case, the winding body 6 is easily manufactured.
