Zipper manufacturing device

The present invention relates to a zipper processing technique, and more particularly to a zipper manufacturing apparatus.

The zipper manufacturing apparatus of the prior art includes a frame and a conveying portion and a processing portion provided on the frame. In the manufacturing process of the zipper, the zipper chain in which a plurality of zippers are connected by a connecting member is transported to the processing portion of the zipper manufacturing apparatus, and the corresponding processing is performed. In this processing, as an example, there is a process of removing a plurality of fastener elements on the fastener chain to form a blank portion on the fastener chain. Specifically, the transport unit provided in the zipper manufacturing apparatus is configured such that the zipper chain is carried in from the loading side of the zipper manufacturing apparatus, and is discharged from the manufacturing apparatus after the processing operation of the zipper chain is completed. Move out. In this process, it is necessary to ensure the continuity and integrity of the chain for the zipper to be processed. However, during the processing, sometimes the connecting members of the chain for the zipper are located at the processing position. That is, the connecting member is directly processed by the processing unit. As a result, not only the connection member is damaged, but also the zipper chain is broken, and there is a case where the processing portion is damaged to some extent. In this case, it is necessary to stop the machining operation, repair the broken chain for the zipper, or restart the zipper manufacturing device after replacing the processing portion. It will also lead to increased costs and reduced efficiency.

The present invention has been made in view of the above disadvantages, and an object thereof is to provide a joint member capable of automatically recognizing a chain for a slide fastener and avoiding a joint structure A zipper manufacturing device that contacts the processing portion.

In order to achieve the above object, the present invention is characterized in that a zipper manufacturing apparatus has a passage for moving a chain for a slide fastener, and a processing portion for performing a specific processing on a chain for a zipper is provided on the passage, and processing is performed. The zipper chain includes a connecting member that moves the zipper chain and moves the zipper chain on the passage, and the zipper chain includes a connecting member for connecting the interrupting portion on the chain, the zipper manufacturing device further includes a detecting portion provided at The processing unit detects the connection member attached to the fastener chain on the upstream side of the passage, and the control unit controls the conveyance so that the machining operation of the machining unit avoids the connection member based on the detection result in the detection unit. Department or processing department.

According to the present invention, when the detecting unit detects the connecting member, for example, the control unit can control the processing operation of the processing unit to avoid the connecting member as follows. In other words, the control unit performs control such that the processing unit does not operate when the current operation is to be performed, and continues the normal operation cycle after the transfer unit transports the connection member to a position beyond the machining position. Alternatively, the conveyance unit is accelerated to move, and when the machining unit performs the machining operation, the connection member has been controlled to reach the position beyond the machining position. Alternatively, the control unit controls the decelerating movement of the conveying unit so that the connecting member does not reach the machining position when the machining unit performs the machining operation. That is, the connection member is controlled so as to avoid the machining operation of the machining portion. Thus, the zipper manufacturing apparatus of the present invention can automatically recognize the connecting member on the chain for slide fasteners, thereby controlling so that the processed portion and the connecting member are not in contact with each other, and the connecting member is not damaged. Making zipper manufacturing When the device is processed, the device will not be stopped due to the breakage of the chain for the zipper or the damage of the processed portion, thereby greatly improving the production efficiency and reducing the cost.

The detecting unit includes a detector, and the detector is a light reflection type detector or a light transmission type detector.

The light reflection type detector detects the reflectance of the connecting member on the fastener chain and other parts (for example, the chain for slide fasteners) with respect to the light reflectance, and outputs a change in the reflectance to the control unit to determine whether or not the light reflectance detector is present. Link the component. Further, since the connecting member is a portion that is opaque to the zipper, when the light transmitting type detector detects the opaque portion, the control unit outputs a signal for detecting the connecting member.

The detecting portion includes a first member and a second member disposed opposite to each other, and has a gap between the first member and the second member for passing the chain for the zipper, on at least one of the first member and the second member The above detector is provided.

With this design, when the chain for the zipper passes the gap between the first member and the second member, the chain for the zipper is disposed such that the front surface and the back surface face the first member and the second member, respectively.

Hereinafter, an example in which the detector is a light transmission type detector will be described. At least one first detector is disposed on the first member, and a second detector is disposed on the second member corresponding to the first detector.

With such a design, one of the first detector and the second detector is a light-emitting element, and the other is a light-receiving element. Moreover, the light emitted from the light-emitting element toward the light-receiving element is transmitted through the fastener tape but is not transmitted. By connecting the members, the presence or absence of the connecting members can be reliably detected.

The zipper manufacturing apparatus further includes a length measuring unit that is disposed on the upstream side of the passage between the processing unit and measures a movement amount of the chain for moving the zipper that is moving in the passage, and the detecting unit is provided in the measurement unit. Long section.

The length measuring portion detects the displacement of the chain for the zipper on the passage, thereby making the control portion easy to control.

The zipper manufacturing device includes a tension applying portion that is provided on the upstream side of the passage of the processing portion, and that applies tension to the fastener chain that is moving in the passage, and the detection portion is provided in the tension applying portion. .

When the tension applying portion is not disposed, when the speed of the chain for the slide fastener changes, one of the chains for the slide fastener may be accumulated due to inertia, which may adversely affect normal processing. However, by providing the tension applying portion on the upstream side of the processing portion, the zipper chain is immediately applied to the tension in the forward direction, and even when the moving speed is rapidly changed, it is not used for the zipper. Stacking occurs on the chain.

The control unit is controlled such that when the detecting unit detects the connecting member, the operation of the processing unit is temporarily stopped, and the connecting member is moved to a position beyond the processing position of the processing unit.

According to this design, when the detecting unit detects the connecting member, the control unit controls the amount of movement of the chain for the slide fastener to avoid contact between the chain for the slide fastener and the processed portion.

Further, when the detecting unit detects the connecting member, the control unit accelerates the movement of the fastener chain to cause the connecting member to reach the super stage when the processing unit is actuated. The conveyance unit is controlled such that the position of the machining position of the machining unit is controlled, or the conveyance unit is controlled such that the fastener chain is decelerated to move the machining unit when the machining unit is not moved to the machining position.

According to this design, when the detecting unit does not detect the connecting member, the control unit directly processes the slide fastener. When the detection unit detects the connection member, the control unit controls the conveyance speed of the conveyance unit to accelerate the movement of the fastener chain 1 so that the connection member reaches the position beyond the machining position, or the chain fastener 1 is decelerated to be connected. The member does not reach the processing position or the like, thereby avoiding contact of the zipper chain with the processing portion.

The present invention has the following advantages and advantageous effects as compared with the prior art.

In the present invention, since the detecting portion is provided in the zipper manufacturing device, the connecting member on the chain for pulling can be automatically recognized. Further, when the connecting member is detected, the conveying unit is controlled such that the connecting member is accelerated to a position beyond the processing position, or the processing unit is temporarily stopped, and the connecting member is moved beyond the processing unit. The way the machining position is controlled. Thereby, the processed portion and the connecting member are not in contact with each other, and the connecting member is not damaged. When the zipper manufacturing device is processed, the zipper chain is not broken or the processed portion is damaged, so that the device stops running, thereby greatly improving production efficiency and reducing cost.

The zipper manufacturing apparatus uses a processing unit to process a fastener chain. In the following, the slide fastener chain 1 to be processed by the present zipper manufacturing apparatus will be described before the zipper manufacturing apparatus of the present invention is described.

In this modification, as shown in the drawing, the coupling member 15 can be replaced with the metal member 18 that connects the front portion 11 and the rear portion 12 of the chain 1 for the fastener. The metal member 18 includes a first metal member 18a that connects the left side chain cloth 16 of the front position portion 11 and the left side chain cloth 16 of the rear position portion 12, and a right side chain that connects the right side chain cloth 16 and the rear position portion 12 of the front position portion 11. The second metal piece 18b of the cloth 16. The metal member 18 has a pair of claw hooks 19, 19' that penetrate the front and back sides of the chain cloth 16. One claw hook 19 penetrates the chain cloth of the front portion 11, and the other claw hook 19' penetrates the chain cloth of the rear portion 12. The claw hooks 19, 19' are bent after passing through the chain cloth 16. Thereby, the connecting member 15 is prevented from coming off the chain cloth 16.

Fig. 4 is a partially enlarged front elevational view of the chain 1 for zipper processed by the processing section. As shown in the figure, the zipper chain 1 is in a specific interval in the length direction. A blank portion 10 formed by removing the fastener elements 17 is formed. The blank portion 10 is formed by punching a sprocket with a punch as a processing portion. That is, the processing portion of the present invention is processed in the following manner. That is, the processing for removing a plurality of fastener elements is performed by the punch in the longitudinal direction of the chain for the zipper to form the blank portion 10 at a specific distance.

<Example 1>

Hereinafter, a zipper manufacturing apparatus according to the present invention will be described with reference to Figs. 5 to 14 . Of course, the zipper manufacturing apparatus can process the zipper chain 1 of each of the above forms.

Figure 5 is a front elevational view of the zipper manufacturing apparatus of the present invention. As shown in Fig. 5, the zipper manufacturing apparatus of the present invention comprises a frame 4 and a passage 6 for moving the chain 1 for zipper. A length measuring portion 5 for measuring the amount of movement of the fastener chain 1 , a processing portion 2 for performing specific processing on the fastener chain 1 , and a chain for moving the fastener chain 1 to the above-mentioned passage are sequentially provided on the passage 6 from the upstream side. 6 transport unit 3.

Further, the passage 6 is provided with a detecting portion 7 which is located on the upstream side of the processing portion 2 and detects the connecting member 15 attached to the fastener chain 1; and the control portion 8 based on the detection result in the detecting portion 7, The conveying unit 3 or the processing unit 2 is controlled so that the machining operation of the processing unit 2 is avoided, and the guide roller 9 is guided further upstream than the length measuring unit 5 and further downstream than the conveying unit 3 The zipper moves with the chain 1.

Hereinafter, each member will be described in detail.

A, length measuring section 5

In the passage 6, the length measuring portion 5 is disposed on the upstream side of the processing portion 2. The length measuring portion 5 includes a bracket 51 fixed to the upper surface of the frame 4, and a length measuring roller 52 supported by the bracket 51. The length measuring roller 52 is in surface contact with one of the front and back sides of the fastener chain 1. Further, the length measuring unit 5 includes a pressing roller 53 that is disposed to face the length measuring roller 52. The pressing roller 53 comes into contact with the other surface of the front and back sides of the fastener chain 1 and presses the fastener chain 1 toward the length measuring roller 52. That is, the fastener chain 1 is sandwiched by the length measuring roller 52 and the pressing roller 53. In a specific operation, frictional resistance is generated between the length measuring roller 52 and the zipper chain 1. Thereby, the length measuring roller 52 rotates together with the movement of the fastener chain 1. The length measuring roller 52 is configured to measure the amount of movement of the fastener chain 1 in accordance with the angle of rotation thereof. Further, the length measuring unit has been described by taking a length measuring unit of a roll type as an example, but a photoelectric measuring unit may be applied. For example, a detected point (for example, a black dot) may be provided on the chain 1 for the zipper, and the number of the detected portions may be counted by the camera as a detecting unit, thereby detecting the transport length of the chain 1 for the zipper.

B, detection department 7

The detecting unit 7 in the present embodiment includes a detector, and the detector is a light reflection type detector or a light transmission type detector. As shown in Fig. 6, in the first embodiment, the detecting portion 7 is a light transmitting type detector. In the drawing, the detecting portion 7 includes a first member 72 and a second member 73 that are disposed opposite to each other. A gap 74 through which the fastener chain 1 passes is provided between the first member 72 and the second member 73. When the zipper chain 1 passes through the gap 74, the first member 72 faces the front side of the zipper chain 1. Further, the second member 73 faces the back surface of the fastener chain 1. Further, the detecting unit 7 includes a base portion 71. The first member 72 and the second member 73 protrude in parallel from the single side of the base portion 71. The base portion 71 is fixed to the bracket 51 (described later) of the length measuring portion 5. The first member 72 and the second member At least one of the 73 is provided with a detector. In the present embodiment, the detector includes a first detector 75 and a second detector 76, and at least one first detector 75 is disposed on a surface of the first member 72 opposite to the second member 73. On the second member 73, a second detector 76 is provided corresponding to the first detector 75 described above. In the present embodiment, the first detector 75 is a light-emitting element, and the second detector 76 is a light-receiving element as an example. The first detector 75 and the second detector 76 are disposed toward the front and back sides of the chain fabric 16 when the fastener chain 1 passes through the gap 74 between the first member 72 and the second member 73. The first detector 75 and the second detector 76 detect the fastener chain 1 or the connecting member 15 that is passing through the gap 74. Here, the number of the first detectors 75 and the number of the second detectors 76 may be one, two or plural. In the present embodiment, two cases will be described as an example. That is, two first detectors 75a, 75b are disposed on the first member 72 in such a manner as to leave a certain distance in the extending direction of the first member 72, and the first detector 75a is disposed on the second member 73. Further, 75b is provided with two second detectors 76a, 76b in such a manner as to leave a certain distance. In addition, the extending direction coincides with the width direction (left-right direction) of the fastener chain 1 . One of the first detectors 75a and one of the second detectors 76a detect the chain cloth 16 on the left side of the fastener chain 1. The other first detector 75b and the other second detector 76b detect the chain cloth 16 on the right side of the fastener chain 1. Further, the detection signal of the detecting unit 7 is transmitted to the control unit 8. Further, as shown in FIG. 5, the detecting unit 7 is attached to the bracket 51 of the length measuring unit 5. Needless to say, the mounting position is not limited thereto, and may be disposed at any position between the length measuring unit 5 and the processing unit 2.

In addition, FIG. 7 is an enlarged view of a main part showing a state in which the detecting unit 7 detects the connecting member 15. As shown in the drawing, the connecting member 15 passes through the gap 74 between the first member 72 and the second member 73 of the detecting portion 7 together with the fastener chain 1. In the case where the chain for zipper is a chain for zipper through which light can pass, the detecting portion 7 may also be a light transmitting type detector. In this case, the light transmitting type detector is attached to one of the first member and the second member. The first detector is set and the second detector is set to the other. Further, either of the first member and the second member is referred to as a light-emitting element, and the other is referred to as a light-receiving element. The light-emitting element emits light, and if it is a chain cloth 16, light is transmitted, and light is received by the light-receiving element. On the other hand, in the case of the connecting member 15, light is not transmitted, and light is not received by the light receiving element. Accordingly, when the detecting unit 7 detects that the light does not pass, the detection unit 7 transmits a detection signal to the control unit 8. Further, in the case where the chain for the zipper is a chain for zipper which is opaque, the detecting portion 7 can be applied with a light reflection type detector, and in this case, the detecting portion 7 detects the reflection from the chain cloth 16 and the connecting member 15. The rate is transmitted to the control unit 8 based on the difference in reflectance. In the case of a reflective detector, the detector is disposed only in one of the first member and the second member.

In addition, FIG. 8 is an operation explanatory diagram (at the time of detection) in which the detecting unit 7 detects the state of the connecting member 15. As shown in FIG. 8, when the detecting unit 7 detects that the connecting member 15 has entered the gap 74 of the detecting unit 7, the detecting unit 7 transmits a signal to the control unit 8, and the control unit 8 activates the transport unit 3 or the processing unit 2 based on the signal. The way to control. The specific operation will be described in detail below.

C, processing department 2

The processing unit 2 for performing specific processing on the zipper chain 1 is erected on The upper surface of the frame 4. In the present invention, the processing unit 2 can be utilized for various processes in accordance with actual requirements. For example, the processing unit 2 includes a punch for forming a blank portion 10 (not shown) in which a plurality of fastener elements 17 are removed at regular intervals in the longitudinal direction of the fastener chain 1. In another example of the processed portion 2, a stopper is attached at every predetermined interval in the longitudinal direction of the fastener chain 1. Alternatively, the cutting is performed at regular intervals in the longitudinal direction of the chain for the slide fastener. Although only a few examples of the processing unit 2 have been described above, the processing unit 2 of the present invention is not limited thereto, and may be configured other than the above-described examples.

D, the transport part 3

In the passage, the conveyance unit 3 that introduces the fastener chain 1 toward the processing unit 2 and discharges the fastener chain 1 from the processing unit 2 is disposed on the downstream side of the processing unit 2 . The conveying unit 3 includes a bracket 31 fixed to the upper surface of the frame 4 and a conveying roller 32 supported by the bracket 31. The conveyance roller 32 is in surface contact with one of the front and back sides of the fastener chain 1, and is rotated by a motor (not shown). Further, the conveying unit 3 further includes a pressing roller 33 that is disposed to face the conveying roller 32. The pressing roller 33 comes into contact with the other surface of the front and back sides of the fastener chain 1 and presses the fastener chain toward the conveying roller. That is, the fastener chain 1 is sandwiched by a conveyance roller and a pressing roller.

In a specific operation, the conveyance roller 32 is driven to rotate by the motor, and the conveyance roller 32 moves the fastener chain 1 by the friction with the fastener chain 1. Thereby, the rotational motion of the motor is changed to the linear movement of the chain 1 for the slide fastener.

E, control unit 8

The control unit 8 of the present embodiment receives the detection signal from the detector 7, and the root According to the detection result in the detecting unit, the conveying unit 3 and/or the processing unit 2 are controlled such that the machining operation of the processing unit 2 avoids the connecting member 15.

Specifically, the control unit 8 has a mode in which the first mode and the second mode in which the transport unit 3 transports the fastener chain 1 are set in the control unit 8 . The first mode is a mode in which the detecting unit 7 does not detect the connecting member 15. The first mode is set as follows. In other words, the transport unit 3 transports the fastener chain 1 to rotate the length measuring roller 52, and the amount of movement of the fastener chain 1 is measured based on the rotation (rotation angle) of the length measuring roller 52. When the predetermined amount of movement is reached, the control unit 8 stops the transport unit 3. Then, the processing unit 2 is actuated. The punch of the processing portion 2 removes the fastener element 17 located directly below the punch from the fastener chain 1. The second mode differs from the first mode in the control of the amount of movement of the chain 1 for the slide fastener. When the detecting unit 7 detects the connecting member 15, the control unit 8 activates the transport unit 3 in the second mode. Specifically, the second mode is set such that the conveyance unit 3 does not measure (rotate) the length measuring roller 52, and conveys the fastener chain 1 by an amount larger than the movement amount in the first mode. In other words, when the detecting unit 7 detects the connecting member 15, the control unit 8 controls the processing unit 2 to temporarily stop, and the connecting member 15 moves to a position beyond the processing position of the processing unit 2, and then the processing is performed. The machining operation of the part 2 is resumed. Moreover, the control unit 8 controls the operation of the transport unit 3 to transport the fastener chain 1 until the connecting member 15 moves to a position beyond the processing position of the processing unit 2. Therefore, the processing operation of the processing unit 2 is avoided by the connecting member 15. Needless to say, the control method of the mode 2 is not limited to this, and may be a control method that changes the conveyance speed of the conveyance unit 3 or less. In other words, the detecting unit 7 detects the connected structure on the premise that the control method of the processing unit 2 is not changed. In the case of the member 15, the conveying unit 3 accelerates the movement of the fastener chain 1 until the connecting member 15 moves to a position beyond the processing position of the processing unit 2. Alternatively, when the detecting unit 7 detects the connecting member 15, the conveying unit 3 decelerates the chain 1 so that the connecting member 15 does not reach the processing position of the processing unit 2. In addition, the processing position is a position immediately below the punch when the processing unit 2 includes a punch.

FIG. 9 is an explanatory view (after detection) of the state in which the detecting unit detects the state of the connecting member. As shown in the figure, when the detecting unit 7 detects the connecting member 15, the connecting member 15 is transported by the conveying unit 3 to a position beyond the conveying roller 32, thereby avoiding the machining operation of the processing unit 2. Of course, in this case, the distance between the connecting member 15 and the processing portion 2 is not limited thereto, and may be other positions as long as the processing operation of the processing portion can be avoided.

Next, the operation of the zipper manufacturing apparatus of the present embodiment will be described. As shown in FIG. 5, the conveyance roller 32 is driven to rotate by the motor, and the conveyance roller 32 moves the fastener chain 1 in the passage 6 by the friction with the fastener chain 1. The length measuring unit 5 measures the moving distance of the fastener chain 1 , and the control unit 8 temporarily stops the fastener chain 1 based on the displacement state of the fastener chain 1 , whereby the processing unit 2 performs the chain 1 for the fastener at its position. machining. Alternatively, when the length measuring unit 5 is not provided, the control unit 8 controls the slide chain 1 to be displaced in the passage 6 at a specific speed, so that the punch of the processing unit 2 is at a specific time. (That is, corresponding to the "zipper chain 1 at a specific distance"), the zipper chain 1 located at the processing position of the processing unit 2 is processed. When the detecting unit 7 does not detect the connecting member 15, the control unit 8 causes the zipper manufacturing device to The above control mode (ie, the first mode) is operated in a manner of control. However, when the detecting unit 7 detects the connection member 15, the control unit 8 operates in the second mode. In other words, the control unit 8 controls the machining unit 2 to temporarily stop the operation, and restores the machining operation of the machining unit 2 after the connection member 15 moves to a position beyond the machining position of the machining unit 2. Thereby, the processing of the processing part 2 is avoided by the connection member 15. Alternatively, the conveyance unit 3 accelerates the movement of the fastener chain 1 without changing the control method of the processing unit 2. Alternatively, the conveying unit 3 decelerates the chain 1 for the slide fastener. As a result, in the zipper manufacturing apparatus, the following operation process is repeated according to the specific situation. In other words, when the detecting unit 7 does not detect the connecting member 15, the control unit 8 controls the processing unit 2 to perform a normal machining operation on the fastener chain 1 . However, when the detecting unit 7 detects the connecting member 15, the control unit 8 controls the processing unit 2 or the conveying unit 3 so that the machining operation of the processing unit 2 avoids the connecting member 15. In this way, the automatic identification of the connecting member 15 on the chain 1 for the zipper can be realized, and the contact of the connecting member 15 with the processed portion 2 can be avoided.

<Example 2>

The present embodiment is similar to the first embodiment, and therefore the same members or components as those of the above-described embodiment are denoted by the same reference numerals. The present embodiment differs from the first embodiment in that, in the zipper manufacturing apparatus, the tension applying unit 100 is further provided on the upstream side of the length measuring unit 5 as shown in FIG. The tension applying portion is supported by a bracket 101 fixed to the upper surface of the frame 4. The detecting unit 7 is provided on the tension applying unit 100. Here, the tension applying unit 100 applies tension (the pulling force in the opposite direction to the conveying direction) to the fastener chain 1 introduced into the processing unit 2, and causes the fastener chain 1 to be free from slack, thereby improving the length measuring unit. Configured for length measurement accuracy.

Hereinafter, the tension applying unit 100 of the present embodiment will be described with reference to Figs. 11 and 12 . The tension applying unit 100 includes a first member 102 and a second member 103 that are opposed to each other in order to sandwich the fastener chain 1 . A gap 111 through which the fastener chain 1 passes is provided between the first member 102 and the second member 103. The tension applying unit 100 and the detecting unit 7 share the first member 102 and the second member 103. That is, the first member 102 of the tension applying portion 100 is also the first member of the detecting portion 7. Further, the second member 103 of the tension applying portion 100 is also the second member of the detecting portion 7. The two first detectors 75a, 75b and the two second detectors 76a, 76b are respectively disposed on the first member 102 and the second member 103, opposite to the second member 103 of the first member 102. Further, a groove portion 104 that extends in the width direction of the first member 102 and that passes the fastener element 17 without interfering with the fastener element 17 of the fastener chain 1 is further provided. Here, the fastener element is disposed only on the front side of the chain 1 for the slide fastener. Thereby, the groove portion 104 is provided only on the first member 102. The groove portion 104 may be formed in the first member 102 and the second member 103 when the fastener elements 17 are disposed on the front and back sides of the fastener chain 1 (in the case of being disposed across the front and back sides of the fastener fabric 16). Both. Moreover, the specific configuration of the tension applying unit 100 is as follows. Further, two through holes are formed in the first member 102 and the second member 103, and the tension adjusting pin 105 is inserted through the through hole (in the present embodiment, the two through holes are taken as an example, but are not limited to two , can also be one or a plurality of through holes). A nut 106 is screwed to one end of the tension adjusting pin 105, and the other end is a large-diameter head 107. A compression spring 108 is further disposed between each of the heads 107 and the first member 102 or between the nut 106 and the second member 103 (preferably Coil spring). Thereby, the first member 102 and the second member 103 are biased such that the first member 102 and the second member 103 are close to each other. Further, at the outer ends of the first member and the second member, a slope which is thinned toward the thickness of the self-zipper chain 1 is formed on the opposing faces of the first member 102 and the second member 103, respectively. Thereby, the opposing faces of the first member 102 and the second member 103 have inclined faces that are inclined toward the direction in which the front ends of the members are gradually separated. By the tilting, the zipper chain 1 can be easily sandwiched between the first member 102 and the second member 103 or the zipper can be pulled from between the first member 102 and the second member 103 during maintenance of the manufacturing apparatus. Use the operation of chain 1.

Further, an adjustment means for adjusting the axial position of the tension adjusting pin 105 (the distance between the head portion 107 and the outer surface of the first member 102) on the upper surface of the head portion 107 of the tension adjusting pin 105 (adjusting member) is provided. (Hexagonal wrench) embedded recess 110 (hexagonal groove). The adjustment tool is embedded in the recess and the adjustment member is rotated, thereby changing the distance between the head 107 of the adjustment member and the outer surface of the first member 102. Thereby, the compression posture of the compression spring 108 is changed, and the force by which the compression spring 108 presses the first member 102 can be adjusted.

In a specific operation, the zipper chain is clamped between the first member 102 and the second member 103 such that the sprocket 17 is located in the groove portion 104. If the position of the nut 106 screwed into the adjustment pin 105 is adjusted, The degree of compression of the compression spring 108 disposed between the head 107 and the first member 102 or between the second member 103 and the nut 106 can then be adjusted. In other words, the magnitude of the clamping force of the tension applying unit 100 to the fastener chain 1 is changed.

<Example 3>

The present embodiment is slightly modified based on the above-described technical solutions of the first embodiment or the second embodiment. Therefore, the same members or components as those of the above-described first embodiment are denoted by the same reference numerals. The difference between the present embodiment and the respective configurations described in the first embodiment or the second embodiment is that a gripper 201 is used as the conveying unit 3 without using the conveying roller 32. As shown in Figs. 13 and 14, in the present embodiment, the configuration of the length measuring unit 5 is omitted. The transport unit 3 includes a left gripper 202 and a right gripper 203 which are respectively disposed on the left side (inside of the paper) and the right side (inside of the paper) of the passage 6, and are provided separately on the left gripper 202 and the right gripper 203. To clamp the zipper chain 1 upper jaw portions 204, 205 and the lower jaw portions 206, 207. In the specific operation, the left gripper 202 and the right gripper 203 respectively hold the zipper chain 1 from both sides in the width direction of the zipper chain 1. That is, the left gripper 202 grips the chain cloth 16 on the left side of the chain 1 for the zipper. Further, the right grip 203 grips the chain cloth 16 on the right side of the chain 1 for the zipper.

Unlike the configuration of the conveyance unit 3 having the above-described configuration, it is necessary to move the conveyance unit 3 from the upstream side position to the downstream side position in the operation (the imaginary line of FIG. 10). The position shown) moves the fastener chain 1 in the direction of the processing part 2. Thereby, the fastener chain 1 is moved from the upstream side to the downstream side. In other words, the transport unit 3 holds the chain 1 for the zipper while continuously holding the chain 1 of the zipper. After the state reaches the specific position on the downstream side (that is, after the chain 1 for the zipper of a certain length is transported), the chain for holding the zipper is released, and the position is returned to the starting position on the upstream side, and the method is continuously repeated in this manner. Do this. Further, when the detecting unit detects the connecting member, the control of the conveying unit is similar to that of the first embodiment, and thus the overlapping description will be omitted.
