The following is a description of the implementation form of the present invention.

Figures 1 to 4 are diagrams of a housing 1 in an implementation form. Figures 5 to 10 are diagrams of a parts storage device 200 in an implementation form. The parts storage device 200 is a device for automatically storing a plurality of parts in the housing 1. First, the housing 1 is described.

FIG. 1 is a three-dimensional view of the housing 1 viewed from the upper side. The housing 1 accommodates the electronic component 50 (shown in FIG. 2 ) as a component in a separated state. The housing 1 is detachably mounted on the feeder 100. In addition, the feeder 100 is a device that discharges the electronic component 50 from the housing 1 by vibration and supplies the electronic component 50 to an unillustrated mounting device. The electronic component 50 of this embodiment is, for example, a tiny rectangular electronic component with a length of 1.2 mm or less in the longitudinal direction. As such an electronic component, capacitors or inductors are listed, but this embodiment is not limited to them.

Figures 2 and 3 are three-dimensional views showing the internal state of the housing 1 after the second component 22 described later is removed. Figure 2 shows the state in which the outlet 6 for discharging the electronic component 50 is open, and Figure 3 shows the state in which the outlet 6 is closed. The outlet 6 is an example of an opening. Figure 4 is a three-dimensional view of the housing 1 viewed from the oblique lower side.

The housing 1 includes a housing body 2, a barrier member 3, a slider 4 integrated with the barrier member 3, and an RFID (Radio Frequency Identification) tag 5.

The housing body 2 has a first component 21 and a second component 22. The housing 1 is a container in which a storage space S is formed by combining the first component 21 and the second component 22. The housing body 2 has a top plate 2U, a bottom plate 2D, a front wall 2F, a rear wall 2B, a right wall 2R on the side of the first component 21, and a left wall 2L on the side of the second component 22. A plurality of electronic components 50 are stored in a separated state inside the housing 1.

In addition, in this specification, when the housing 1 is set on the feeder 100, the up-down direction of the lead vertical direction is set as the up-down direction of the housing 1. In addition, the side of the housing 1 where the discharge port 6 is set is set as the front, and the opposite side is set as the rear. The left and right directions of the left and right sides are set as the left and right directions when the housing 1 is observed from the front. The first component 21 is located on the right side, and the second component 22 is located on the left side. The housing 1 has a flat box shape that is longer in the front-back direction and thinner in the left-right direction.

Each of the front wall portion 2F, the rear wall portion 2B, the right wall portion 2R, and the left wall portion 2L is a wall portion extending in the vertical direction, i.e., the up-down direction. Each of the top plate portion 2U and the bottom plate portion 2D is a plate portion extending in the horizontal direction, i.e., the front-back direction (length direction).

As shown in FIG. 1 and FIG. 4 , the housing 1 is formed by combining the first component 21 and the second component 22 which are symmetrically formed on the left and right and joining them together. That is, each of the first component 21 and the second component 22 is a half body divided into left and right parts.

The housing body 2 has a discharge port 6 on the lower side of the front wall portion 2F. The discharge port 6 is a quadrilateral opening in the embodiment. In addition, the discharge port 6 is not limited to a quadrilateral, and may be an opening with a circular or elliptical outline, for example.

As shown in FIG. 2 , a plate member 7 extends between the first member 21 and the second member 22 in the storage space S. The upper surface of the plate member 7 extends from the rear to the lower edge 6a of the discharge port 6 in the front, and forms an inclined surface 7a that is inclined in a manner such that the lower edge 6a side becomes the lowest side. The inclination angle θ of the inclined surface 7a is preferably 3° to 10° relative to the horizontal direction when the housing 1 is set on the feeder 100, and is more preferably 5° to 7°.

As shown in FIG. 2 , the barrier member 3 for opening and closing the discharge outlet 6 extends continuously from the bottom plate portion 2D to the front wall portion 2F. The barrier member 3 opens and closes the discharge outlet 6 by sliding along its own extension direction. The barrier member 3 can extend continuously from the bottom plate portion 2D to the front wall portion 2F and slide along its extension direction. The barrier member 3 is a thin and long strip-shaped film member. The barrier member 3 includes, for example, PET (Polyethylene terephthalate) and other materials that have a certain degree of rigidity and can be bent. The width of the barrier member 3 is slightly larger than the width of the discharge outlet 6, and has a width that can cover the discharge outlet 6 without a gap.

The gate member 3 has an opening portion 3a at its front end that is roughly the same shape as the discharge port 6. If the opening portion 3a matches the discharge port 6, the discharge port 6 is open. When the gate member 3 covers the discharge port 6, the discharge port 6 is closed by the gate member 3. In addition, the opening portion 3a does not need to be the same shape as the discharge port 6, as long as it has a shape and size that allows the discharge port 6 to open.

A recessed portion 61 is provided on the upper side of the discharge port 6 in the front side wall portion 2F of the housing body 2, which is recessed from the outside of the housing body 2 to the inside. A pair of guide grooves 62 extending in the vertical direction are provided in the thickness direction, i.e., the left-right direction, of the front side wall portion 2F where the discharge port 6 and the recessed portion 61 are provided. Each of the two side portions extending in the length direction of the barrier member 3 is inserted into the left and right guide grooves 62. The barrier member 3 is guided by the guide grooves 62 and slides in the vertical direction on the front side wall portion 2F.

As shown in FIG2 and FIG3, a circular hole 3b is provided at the rear end of the gate member 3. The slide 4 is installed in a manner of being integrated with the gate member 3 by using the hole 3b. The slide 4 is a rectangular member, and as shown in FIG4, has a lower side opening portion 4c opened at the bottom, and has a front end plate portion 4d and a rear end plate portion 4e.

As shown in FIG. 2 and FIG. 3 , the slider 4 has flanges 4a extending in the left and right directions at its upper end. The slider 4 has a convex portion 4b on its upper surface. The convex portion 4b is engaged with the hole 3b of the gate member 3 and protrudes upward, whereby the slider 4 and the gate member 3 become one body.

As shown in FIG4 , a recess 23 that is recessed upward and is longer in the front-to-back direction is provided on the bottom plate portion 2D of the housing 1. A slit 24 is provided on the front surface of the recess 23. The rear end of the barrier member 3 is inserted through the slit 24. The rear end of the barrier member 3 extends along the lower surface of the recess 23 through the slit 24. On the lower surface of the recess 23, the recess 26a and the recess 26b are provided in a front-to-back pair. The protrusion 4b of the slider 4 can be fitted into each of the recess 26a and the recess 26b.

On the left and right sides of the bottom plate 2D where the recess 23 is provided, grooves 25 extending forward and backward are provided. The left and right flanges 4a of the slider 4 are inserted into the left and right grooves 25, respectively. The slider 4 slides forward and backward by sliding the flanges 4a along the grooves 25. At this time, the sliding range of the slider 4 is between the position where the projection 4b is engaged with the recess 26a on the front side and the position where the recess 26b is engaged with the rear side.

As shown in FIG3, when the protrusion 4b of the slider 4 is engaged with the recess 26a on the front side, the opening 3a of the gate member 3 is located in the recess 61 and does not match the discharge port 6. At this time, the entire discharge port 6 is closed by the gate member 3, and the electronic component 50 is not discharged from the discharge port 6 to the outside. On the other hand, when the gate member 3 slides to the rear, as shown in FIG2, the protrusion 4b is engaged with the recess 26b on the rear side, and the opening 3a of the gate member 3 matches the discharge port 6. At this time, the discharge port 6 is open, and the electronic component 50 can be discharged from the discharge port 6.

As shown in FIG. 1 and FIG. 2 , the housing body 2 has an upper gripping portion 10A and a rear gripping portion 10B. The upper gripping portion 10A is a pair of grooves disposed at the front and rear ends of the upper side of the housing body 2. The rear gripping portion 10B is a pair of grooves disposed at the upper and lower ends of the rear side of the housing body 2. Each of the upper gripping portion 10A and the rear gripping portion 10B is gripped by a robot when the housing 1 is carried by the robot, for example.

As shown in Figures 1 and 2, a through hole 9 is provided at the lower part of the housing body 2 and roughly corresponding to the above-mentioned recess 23. The through hole 9 is a slit-shaped hole extending in the front-back direction. A strip-shaped RFID tag 5 that is longer in the front-back direction is attached to the upper surface of the inner part of the through hole 9. The RFID tag 5 is a well-known structure having a transceiver, a memory, and an antenna. As shown in Figure 1, a reader/writer 105 for reading and writing information on the RFID tag 5 is arranged on the feeder 100.

As shown in Figures 1 to 4, the housing body 2 further has a claw portion 8 and a T-groove portion 13 extending from the outer surface of the bottom plate portion 2D to the bottom.

The claw portion 8 includes a front claw portion 8A and a rear claw portion 8B. The front claw portion 8A and the rear claw portion 8B are of the same shape, that is, a plate extending from the top to the bottom, with the lower end bent approximately 90 degrees to the rear, and in a side view, in an L-shaped shape. In addition, the front claw portion 8A and the rear claw portion 8B may not be of the same shape.

The T-groove portion 13 includes a front T-groove portion 13A and a rear T-groove portion 13B. Both the front T-groove portion 13A and the rear T-groove portion 13B are inverted T-shaped protrusions when viewed from the front. The front T-groove portion 13A has a tapered tapered portion 13c formed at the front end.

The feeder 100 has a claw portion 8 and a T-slot portion 13 that can be detachably engaged, and the housing 1 can be set on the unillustrated engaging portion of the feeder 100. The claw portion 8 and the T-slot portion 13 are engaged with each other on the engaging portion, and the housing 1 is detachably set on the feeder 100. In this way, in the housing 1 set on the feeder 100, the feeder 100 is vibrated with the discharge port 6 opened, so that the electronic component 50 falls along the inclined surface 7a and is discharged from the discharge port 6. The discharged electronic component 50 is supplied to the mounting device as described above.

Next, the parts storage device 200 of the embodiment will be described with reference to FIGS. 5 to 10.

FIG. 5 is a top view showing the outline of the parts receiving device 200, and FIG. 6 is a partial cross-sectional view corresponding to the VI-VI line of FIG. 5 .

The component storage device 200 is a device that automatically stores a plurality of electronic components 50 in the housing 1 through the discharge port 6 into the storage space S. As shown in FIG. 5 and FIG. 6 , the component storage device 200 in the embodiment includes: a conveying part 210 that conveys the electronic components 50; a discharge part 230 that causes the electronic components 50 to fall from the conveying part 210 and be discharged; a setting part 240 that sets the housing 1; and a component detection part 270.

The conveying section 210 continuously conveys a plurality of electronic components 50 to the discharge section 230. The conveying section 210 of the embodiment has: a linear feeder 211, which continuously conveys a plurality of electronic components 50 in a straight line; and a turntable 212, which receives the plurality of components conveyed by the linear feeder 211 one by one, and intermittently conveys the electronic components 50 by rotating the electronic components 50 through a rotating action.

A plurality of electronic components 50 are transported to a turntable 212 in a row by a linear feeder 211 arranged approximately horizontally. The linear feeder 211 is vibrated, for example, by a vibrator not shown, and the electronic components 50 are transported to the turntable 212 in sequence in the direction of arrow F by the vibration. The electronic components 50 are pushed by the subsequent electronic components 50 while being transported on the linear feeder 211. The linear feeder 211 extends toward the rotation center of the turntable 212, and its terminal end reaches near the outer periphery of the turntable 212.

The turntable 212 is a horizontally arranged disc-shaped rotating component. The material of the turntable 212 includes ceramics, epoxy glass resin, etc. The turntable 212 is rotatably arranged on the base 214 via the rotating shaft 213 extending in the vertical direction. The turntable 212 is rotated intermittently in the direction of the arrow R in Figure 5 with the rotating shaft 213 as the center by the driving source 217 that drives the rotating shaft 213. On the outer periphery of the turntable 212, a plurality of notches 215 opening on the outer peripheral side are arranged at equal intervals in the circumferential direction. Inside one notch 215, one electronic component 50 is accommodated. In addition, the rotation direction of the turntable 212 is not limited to the R direction in Figure 5, and can also be the opposite direction of the R direction.

As shown in FIG6 , the turntable 212 is disposed on the upper surface 216 of the base 214. The notches 215 are opened on the outer peripheral surface side and the upper and lower surfaces of the turntable 212. The turntable 212 has an air suction passage (not shown) inside thereof that leads to each notch 215. The air suction passage opens on the deep side surface of each notch 215. The air suction passage is connected to a suction source such as a vacuum pump, and the air in the notch 215 is sucked to the deep side surface by the actuation of the suction source to form a negative pressure state. In this way, the electronic component 50 accommodated in the notch 215 is adsorbed on the deep side surface by the negative pressure action and is kept in the notch 215.

The electronic components 50 transported by the linear feeder 211 to the vicinity of the turntable 212 are received one by one from the side in each of the plurality of notches 215 of the intermittently rotating turntable 212, and are adsorbed and held on the deep side surface as described above. The electronic components 50 received and held in the notches 215 are intermittently transported to the discharge portion 230 in the direction of arrow R by the rotation of the turntable 212. The electronic components 50 received in the notches 215 move on the upper surface 216 of the base 214.

The discharge section 230 is arranged corresponding to the turntable 212. Specifically, the discharge section 230 is arranged in a circular conveying path corresponding to the rotation track of the notch 215 of the turntable 212. The discharge section 230 is arranged at a rotation angle position of approximately 270° relative to the portion moved from the linear feeder 211 to the turntable 212. The discharge section 230 is a portion that allows the electronic components 50 conveyed by the turntable 212 to fall one by one by their own weight to the discharge port 6 of the housing 1 provided in the setting section 240.

In addition, the discharge portion 230 can be arranged at any position of the turntable 212, for example, it can also be arranged at the deepest position observed from the linear feeder 211, that is, the rotation angle position of 180° relative to the part moved from the linear feeder 211 to the turntable 212.

As shown in FIG. 7 , the discharge section 230 includes a cylindrical member 231 and a pressing pin 236. In the discharge section 230, a through hole 218 corresponding to the notch 215 of the turntable 212 is provided at the portion directly below the turntable 212. The through hole 218 has a size for the electronic component 50 to pass through. In addition, the discharge section 230 is provided with a suction release mechanism (not shown) for releasing the electronic component 50 from being attracted and held by suctioning air into the notch 215. As the suction release mechanism, for example, a mechanism for ejecting air to stop or weaken the flow of the attracted air can be used. If the turntable 212 rotates and the notch 215 is aligned with the through hole 218, the electronic component 50 held in the notch 215 is released by the above-mentioned suction release mechanism, and the electronic component 50 that has been moving on the upper surface 216 of the base 214 at that time falls from the notch 215 to the through hole 218, and then falls through the through hole 218 to the inside of the cylindrical component 231.

The electronic component 50 that falls through the through hole 218 is guided to the discharge port 6 of the housing 1 by passing through the inside of the funnel-shaped cylindrical member 231. The cylindrical member 231 has an upper cylindrical portion 233 with an inverted cone shape whose inner diameter increases as it goes upward, and a lower cylindrical portion 234 that extends downward from the center of the lower end of the upper cylindrical portion 233. The upper cylindrical portion 233 and the lower cylindrical portion 234 are integrated. The electronic component 50 that passes through the through hole 218 falls from the inner side of the upper cylindrical portion 233 to the inside of the lower cylindrical portion 234, and falls through the inside of the lower cylindrical portion 234. The electronic component 50 sometimes slides down while contacting the inner surface 232 of the cylindrical member 231.

In addition, it is preferred that the inner diameter of the upper tube portion 233 is larger than the lengthwise dimension of the electronic component 50, and the inner diameter of the lower tube portion 234 is larger than the lengthwise dimension of the electronic component 50 and smaller than the inner diameter of the upper tube portion 233.

In order to prevent the electronic component 50 from being electrically damaged by static electricity generated by friction, at least the inner surface 232 of the cylindrical component 231 is preferably made of a conductive material including a conductive metal. In addition, in order to allow the electronic component 50 to slide smoothly, the inner surface 232 of the cylindrical component 231 is preferably a smooth low-friction surface, for example, preferably surface-processed by a resin such as a fluorine resin.

A pressing pin 236 is provided in the discharge portion 230 to force the electronic component 50 to fall from the notch 215. The pressing pin 236 is arranged at the upper position of the notch 215 that matches the through hole 218. The pressing pin 236 is a rod-shaped component extending in the up-down direction, and is driven in the up-down direction by an actuator not shown. When the pressing pin 236 is driven downward, the electronic component 50 in the notch 215 is pushed downward, so that it passes through the through hole 218 and falls into the inside of the cylindrical component 231. By pressing with the pressing pin 236, the electronic component 50 is surely separated from the notch 215 and falls without being stuck in the notch 215.

In addition, an air flow generating unit 237 that causes the electronic component 50 to fall from the notch 215 by the flow of air may be provided in the discharge unit 230 instead of or in addition to the pressing pin 236. Examples of such an air flow generating unit 237 include a unit that has the function of blowing air from above to cause the electronic component 50 to fall, or a unit that sucks air from the side to cause the electronic component 50 to fall, etc.

Furthermore, the discharge section 230 is provided with a cleaning section 238 for cleaning the path of the electronic component 50 passing through the discharge section 230. Specifically, the cleaning section 238 is arranged above the pressing pin 236 and is composed of an air suction mechanism for sucking air. By sucking air through the cleaning section 238, the air in the path of the electronic component 50, which is the inside of the notch 215, the through hole 218 and the cylindrical member 231, is sucked in. In this way, the debris or dust existing in the path is sucked into the cleaning section 238 and cleaned.

In addition, the cleaning part 238 can also clean the path of the electronic component 50 by blowing away debris or dust by spraying air. In this case, in order to prevent debris or dust from entering the housing 1, the discharge port 6 is closed by the blocking member 3.

FIG8 shows a state where the housing 1 is installed in the installation part 240. The housing 1 is installed in the installation part 240 in a state where the electronic component 50 discharged from the discharge part 230 falls to the discharge port 6. The housing 1 is installed in the installation part 240 in a state where the front-back direction of the housing 1 is along the lead vertical direction, that is, in a longitudinal state.

The installation portion 240 has a wall portion 241, a holding portion 250 that holds the housing 1 in a vertical position on the wall portion 241, and an opening and closing mechanism 260 that opens and closes the shutter member 3 of the housing 1.

The wall portion 241 has a surface along a substantially vertical direction, namely, a wall surface 241a.

The holding portion 250 includes a pair of hooks protruding from the wall surface 241a, namely, an upper hook portion 251 and a lower hook portion 252. The upper hook portion 251 and the lower hook portion 252 are of the same shape, that is, a plate having an L-shaped shape in side view with the front end bent upward at approximately 90 degrees. As shown in FIG. 9 , the front claw portion 8A of the housing 1 is detachably engaged with the upper hook portion 251 from above, and the rear claw portion 8B of the housing 1 is detachably engaged with the lower hook portion 252 from above. In this way, the housing 1 is detachably held in the holding portion 250 in a longitudinal state with the discharge port 6 facing upward and the front-rear direction, i.e., the length direction, extending in the vertical direction along the wall surface 241a. The bottom plate 2D of the housing 1 has a gap and faces the wall surface 241a in parallel. In addition, the upper hook 251 and the lower hook 252 may not be of the same shape.

A recess 242 extending in the vertical direction and opening on the side of the wall surface 241a is formed in the wall portion 241. An opening and closing mechanism 260 for sliding the gate member 3 is arranged in the recess 242. The opening and closing mechanism 260 has a driving pin 261 movably arranged in the vertical direction along the bottom surface of the recess 242. The front end portion of the driving pin 261 protrudes from the wall surface 241a. The driving pin 261 is supported movably in the vertical direction along a guide groove arranged on the bottom surface of the recess 242, for example, and is reciprocated in the vertical direction by an actuator or the like. A reader/writer 243 that can write information to the RFID tag 5 in a non-contact manner is arranged in the recess 242 of the wall portion 241.

As shown in FIG9 , the driving pin 261 is engaged with the slide 4 of the housing 1 held in the holding portion 250. The gate member 3 of the housing 1 shown in FIG9 slides to the front (upward in FIG9 ), the protrusion 4b of the slide 4 is engaged with the recess 26a on the front side, and the discharge port 6 is closed by the gate member 3. On the other hand, the driving pin 261 moves upward. When the driving pin 261 is located at the upper side, if the housing 1 whose discharge port 6 is closed by the gate member 3 is held in the holding portion 250, the driving pin 261 is inserted into the lower side opening 4c of the slide 4 shown in FIG4 , and is positioned between the front end plate 4d and the rear end plate 4e.

In FIG. 9 , if the driving pin 261 moves downward from this state, the driving pin 261 contacts the rear end plate 4e of the slider 4, pressing the slider 4 downward to slide. As the slider 4 slides downward, the barrier member 3 slides to the rear in the housing 1. Thus, as shown in FIG. 10 , the protrusion 4b of the slider 4 fits into the recess 26b on the rear side, the opening 3a of the barrier member 3 aligns with the discharge port 6 of the housing 1, and the discharge port 6 opens. When the driving pin 261 returns upward from this state, the driving pin 261 contacts the front end plate 4d of the slider 4, pressing the slider 4 upward to slide. By sliding the slider 4 upward, the gate member 3 slides to the front of the housing 1, as shown in Figure 9, the protrusion 4b is engaged with the recess 26a on the front side, and the opening 3a is closed by the gate member 3.

The component detection unit 270 detects the electronic component 50 at any position of the path of the electronic component 50 between the conveying unit 210 and the discharge port 6 of the housing 1 provided in the installation unit 240. The component detection unit 270 of the implementation form includes a first component detection unit 271 arranged at a specific position on the side of the linear feeder 211 shown in FIG5, a second component detection unit 272 and a third component detection unit 273 arranged on the turntable 212, and a fourth component detection unit 274 provided in the discharge unit 230 shown in FIG7.

The first part detection unit 271 detects the electronic part 50 conveyed by the linear feeder 211 at a fixed position. The second part detection unit 272 is arranged on the upstream side of the conveying path of the turntable 212. The third part detection unit 273 is arranged on the downstream side of the second part detection unit 272 in the conveying path of the turntable 212.

Each of the first part inspection unit 271, the second part inspection unit 272, and the third part inspection unit 273 inspects any item related to the electronic component 50. The first part inspection unit 271, for example, has the function of a counter that detects the passage of the electronic component 50 and counts the number of electronic components 50 that have passed. The second part inspection unit 272 is, for example, an image sensor that detects the shape of the electronic component 50 and detects whether the electronic component 50 has a shape defect based on the detected shape. The third part inspection unit 273, for example, functions as a performance inspection unit that detects the performance of the electronic component 50. The performance inspection unit, for example, when the electronic component 50 is a capacitor, is used as an electrostatic capacitance sensor that functions to detect whether the electrostatic capacitance has a specified value.

The fourth part detection section 274 includes an upstream side passage detection section 275 and a downstream side passage detection section 276 disposed at respective positions of the upstream side and the downstream side of the cylindrical member 231. The upstream side passage detection section 275 is located at the upstream side of the cylindrical member 231 and has a function as a counter for counting the number of electronic parts 50 passing through the passage hole 218 and entering the cylindrical member 231. The upstream side passage detection section 275 uses a well-known photo sensor composed of a light-emitting element 275a and a light-receiving element 275b. The downstream side passage detection section 276 is located at the downstream side of the cylindrical member 231 and has a function as a counter for counting the number of electronic parts 50 passing through the cylindrical member 231 and entering the discharge port 6 of the housing 1. The downstream side passing detection unit 276 also uses a well-known photo sensor composed of a light emitting element 276a and a light receiving element 276b, similarly to the upstream side passing detection unit 275. In addition, as a photo sensor, it is a form that receives the reflection of the light emitted from the object, and it can also be a light emitting element and a light receiving element that are not separated and are integrated.

According to the component storage device 200 of the above embodiment, the electronic component 50 is stored in the housing 1 as shown below.

The electronic components 50 are transported one by one to the turntable 212 by the linear feeder 211. The electronic components 50 are detected by the first component detection unit 271. In the first component detection unit 271, for example, the number of electronic components 50 transported is counted. One electronic component 50 is received in the notch 215 of the turntable 212 which is rotating intermittently from the linear feeder 211. During the intermittent rotation of the turntable 212, the electronic component 50 in the notch 215 is detected by the second component detection unit 272 and the third component detection unit 273.

In the second component inspection section 272, for example, the shape of the electronic component 50 is inspected, and whether the electronic component 50 has shape defects is inspected based on the inspected shape. In the third component inspection section 273, for example, the performance of the electronic component 50 is inspected. If the electronic component 50 is judged to be defective by inspection in the second component inspection section 272 and the third component inspection section 273, the electronic component 50 is removed from the turntable 212.

The electronic components 50 are transported to the discharge section 230 one by one by the turntable 212. In the discharge section 230, when the notch 215 is aligned with the through hole 218, the pressing pin 236 descends to press the electronic component 50 downward. The electronic component 50 falls from the notch 215 to the through hole 218, and then enters the inside of the cylindrical component 231 through the through hole 218, falls in the cylindrical component 231, and falls from the discharge port 6 of the shell 1 and is received in the shell 1. At this time, the electronic component 50 falling from the notch 215 enters the cylindrical component 231 through the detection section 275 on the upstream side of the fourth component detection section 274, and the electronic component 50 falling from the cylindrical component 231 enters the shell 1 through the detection section 276 on the downstream side.

The above actions are performed continuously to accommodate multiple electronic components 50 in the housing 1. During the conveying process on the linear feeder 211, the first component detection unit 271 counts the number of electronic components 50 conveyed. In addition, the fourth component detection unit 274, which includes the detection unit 275 on the upstream side and the detection unit 276 on the downstream side, counts the number of electronic components 50 that fall from the notch 215 and are finally accommodated in the housing 1. When the number of electronic components 50 accommodated in the housing 1 reaches a specific number, the conveying unit 210 stops conveying the electronic components 50, replaces the setting unit 240 with a new empty housing 1, and then restarts the accommodation of electronic components 50 in the housing 1.

According to the above-described implementation form of the parts storage device 200, the following effects are achieved.

(1) The component storage device 200 of the embodiment is a rectangular parallelepiped having a longitudinal direction, having a discharge port 6 as an opening at one end of the longitudinal direction, and having a shutter member 3 for opening and closing the discharge port 6 by sliding, and is provided with a plurality of electronic components 50 from the discharge port 6, and has: a conveying portion 210 for continuously conveying the plurality of electronic components 50; a discharge portion 23 0, which makes the electronic components 50 transported by the transporting part 210 fall one by one by their own weight; and the setting part 240, which sets the housing 1 in a positioned state in a manner that the electronic components 50 discharged from the discharge part 230 fall to the discharge outlet 6; and the setting part 240 has: a holding part 250, which can hold the housing 1 with the discharge outlet 6 facing upward; and an opening and closing mechanism 260, which opens and closes the gate member 3.

In this way, multiple electronic components 50 can be automatically accommodated in the housing 1.

Since the housing 1 is held in the holding portion 250 of the setting portion 240 with the discharge port 6 facing upward, the electronic components 50 can be smoothly accommodated in the housing 1 from the discharge port 6, and the electronic components 50 are not discharged from the discharge port 6 due to gravity, and a specific number of electronic components 50 are surely accommodated.

The discharge port 6 of the housing 1 can be easily opened and closed by sliding the barrier member 3 through the opening and closing mechanism 260 while being held in the holding portion 250. By disassembling from the holding portion 250 and the housing 1 while the discharge port 6 is closed by the barrier member 3, the electronic component 50 can be prevented from accidentally spilling out of the discharge port 6 during disassembly.

(2) In the part storage device 200 of the embodiment, it is preferred that the retaining portion 250 can retain the housing 1 in a longitudinal position with its length direction substantially in the vertical direction.

Thus, since the electronic component 50 can be housed in the housing 1 without any gaps due to gravity, the electronic component 50 can be housed quickly without vibrating or shaking the housing 1.

(5) In the part storage device 200 of the embodiment, it is preferred that the slider 4 is integrally provided on the gate member 3, and the opening and closing mechanism 260 includes a driving pin 261 that is engaged with the slider 4 and opens and closes the gate member 3 by reciprocating movement.

In this way, the gate member 3 can be actuated to open and close the outlet 6 with a simple structure. By disassembling from the retaining portion 250 and the housing 1 in a state where the outlet 6 is closed by the gate member 3, the electronic component 50 can be prevented from accidentally spilling out of the outlet 6 during disassembly.

Next, other embodiments are described with reference to FIGS. 11 to 14. The other embodiments are different from the above-mentioned embodiments in that the housing 1 is set in the setting portion 240, but the other structures are the same. Therefore, in the description of other embodiments, the same symbols are marked for the same components as the above-mentioned embodiments, and the related descriptions are omitted or simplified, and the differences are mainly described.

In other embodiments, the housing 1 is not directly disposed on the wall 241, but is disposed on the wall 241 via the retaining portion 300 shown in FIG. 11. The retaining portion 300 is disposed on the wall 241 to accommodate the housing 1 therein, and constitutes a part of the parts accommodating device 200 of other embodiments.

As shown in FIG. 11 , the holding portion 300 includes a bottom plate portion 301, a pair of side walls 302 and 303 that stand upward from the bottom plate portion 301 and face each other, and an upper plate portion 305. Inside the holding portion 300, there is a housing receiving portion 300a surrounded by the bottom plate portion 301, the side walls 302, the side walls 303, and the upper plate portion 305. In the embodiment, the bottom plate portion 301, the side walls 303, and the upper plate portion 305 are integrated, and the side walls 302 have the function of a cover that can be attached and detached relative to the bottom plate portion 301 and the side walls 303. The side walls 302 are opened and closed at an opening portion 300b that is opened on the side. The housing 1 is inserted into the holding portion 300 from the opening 300b in a horizontal direction with the discharge port 6 facing upward and the front-rear direction along the up-down direction, and is accommodated in the housing accommodation portion 300a. Thereafter, the side wall portion 302 is closed. In addition, the holding portion 300 may also omit the side wall portion 302 as a cover. In this case, the housing 1 is inserted into the holding portion 300b in a horizontal direction and accommodated in the holding portion 300, and the opening portion 300b is in an open state.

A hole 300c is provided on the upper plate 305, which passes through the inside and outside of the retaining part 300. The cylindrical component 231 of the discharge part 230 is arranged in the hole 300c with the upper cylindrical part 233 facing upward. The upper end opening of the upper cylindrical part 233 of the cylindrical component 231 protrudes above the upper plate 305, and the lower end of the lower cylindrical part 234 is arranged on the inner side of the discharge port 6 of the shell 1.

The retaining portion 300 has an upper hook portion 251 and a lower hook portion 252 on the inner surface of one side wall portion 303, which are the same as those in the above-mentioned embodiment. In addition, a recess 304 is formed between the upper hook portion 251 and the lower hook portion 252 on the inner surface of the side wall portion 303. An opening and closing mechanism 260 having a driving pin 261 is arranged in the recess 304. The driving pin 261 is arranged to be movable in the up-down direction along the bottom surface of the recess 304. A reader/writer 243 for reading and writing information on the RFID tag 5 is arranged in the recess 304. The retaining portion 300 can be rocked in the direction of arrow G in FIG. 11 via the rotating shaft 310, and can be installed on the wall portion 241 of the above-mentioned embodiment so as to stop at any rocking angle position.

As shown in FIG. 11 , the front claw 8A is detachably engaged with the upper hook 251 from above, and the rear claw 8B is detachably engaged with the lower hook 252 from above, and the housing 1 is held inside the side wall 303. The housing 1 is held in a longitudinal state with the discharge port 6 facing upward and the front-rear direction, i.e., the length direction, extending in the vertical direction along the side wall 303. The bottom plate 2D of the housing 1 is spaced apart and faces the side wall 303 in parallel. The lower end of the lower side cylinder 234 in the cylinder member 231 disposed on the upper plate 305 is disposed inside the discharge port 6 of the housing 1. The rotation axis 310 of the retaining portion 300 is arranged at a position where its axis passes through the vicinity of the opening center of the upper side cylinder portion 233 of the cylindrical member 231.

In this way, the RFID tag 5 of the housing 1 held in the holding portion 300 is read and written by the reader/writer 243. In addition, although the reader/writer 243 of the embodiment is arranged in the pit 304 near the bottom plate portion 301 provided on the side wall portion 303, the position of the reader/writer 243 is not limited thereto. For example, it can also be arranged at a position close to the upper plate portion 305 on the inner surface of the side wall portion 303 (the position shown in 243B of FIG. 11). In addition, it can also be arranged at a position close to the upper plate portion 305 on the inner surface of the other side wall portion 302 (the position shown in 243C of FIG. 11), or at a position close to the bottom plate portion 301.

In this embodiment, for example, the rotation angle position of the holding portion 300 centered on the rotation axis 310 is set to a state where the length direction of the housing 1 is along the up-down direction as shown in FIG. 11, and similarly to the above-mentioned embodiment, the electronic component 50 dropped from the discharge portion 230 drops from the discharge port 6 through the cylindrical member 231 and is received in the housing 1.

Furthermore, as shown in FIG. 12 , the housing 1 can be used as follows: the holding portion 300 is rotated to hold the housing 1 in an inclined state in which the longitudinal direction thereof is inclined at a specific angle relative to the vertical direction, and in this state, the electronic component 50 is dropped from the discharge port 6 and stored in the housing 1. In this way, by holding the housing 1 at an angle, the electronic component 50 can be dropped onto the inclined inclined surface 7a at the initial stage of storage, thereby reducing the impact of the electronic component 50 being dropped and preventing damage to the electronic component 50.

Furthermore, in this embodiment, as shown in FIG. 13(a), the following method of use can be adopted: the electronic components 50 are first accommodated in a state where the housing 1 is tilted to a certain extent by the holding portion 300, and then, as shown in FIG. 13(b), the housing 1 is gradually moved closer to the longitudinal position as the number of accommodated components increases, and finally, as shown in FIG. 13(c), the accommodation is completed in the longitudinal position. In this way, the impact on the electronic components 50 can be further weakened, and the electronic components 50 can be prevented from overflowing from the discharge port 6.

In addition, the housing 1 with the rotation axis 310 as the center can be tilted not only toward one side (the left side in FIG. 13 ) as shown in FIG. 13 , but also toward the other side, and can also be rocked in the left and right directions in FIG. 13 .

Furthermore, it can also be set so that the housing 1 is rocked and tilted on both sides in a plane along the width direction of the housing 1 (the front and back directions of the paper in FIG. 13 ) with the position of the rotation axis 310 as the center.

In addition, regardless of whether the housing 1 is placed vertically or obliquely, the intersection angle (θ2 in FIG. 12 ) between the inclined surface 7a in the housing 1 and the gravity direction extending downward from the terminal end of the inclined surface 7a is always a sharp angle. Since θ2 is a sharp angle, the electronic component 50 supplied from the discharge port 6 is also affected by gravity and is easily accommodated in the housing 1. On the other hand, as shown in FIG. 1 , in the use state of the housing 1 in which the housing 1 is placed horizontally and the electronic component 50 is supplied from the discharge port 6, the intersection angle (θ1 in FIG. 2 ) between the inclined surface 7a and the gravity direction extending downward from the terminal end of the inclined surface 7a is a blunt angle. By making θ1 a blunt angle, the electronic component 50 housed in the housing 1 is also affected by gravity and is easily discharged out of the housing 1. In addition, in the housing 1 of the embodiment, it is desired that θ2 is a sharp angle, but even if it is not a sharp angle, as long as θ1>θ2. In this way, the electronic component 50 supplied from the discharge port 6 to the housing 1 can be suppressed from being discharged from the discharge port 6 again. In addition, it is desired that θ2>0°. In this way, the electronic component 50 supplied from the discharge port 6 temporarily collides with the inclined surface 7a, which can shorten the falling distance of the electronic component 50. Therefore, the impact of the falling of the electronic component 50 can be weakened.

(3) In the embodiment of the parts storage device 200, it is preferred that the other embodiments described above are used, and the retaining portion 300 as a retaining portion can retain the housing 1 in a tilted state in which its length direction is tilted at a specific angle relative to the vertical direction of the lead.

By accommodating the electronic component 50 while the housing 1 is tilted, the impact of the electronic component 50 being dropped can be reduced, and damage to the electronic component 50 can be suppressed.

(4) In the embodiment of the parts storage device 200, it is preferred that the other embodiments described above be used, and the holding portion 300 as a holding portion can maintain the housing 1 from a tilted state at a specific angle relative to the vertical direction of the lead in its length direction to a longitudinal state substantially along the vertical direction of the lead.

This can further reduce the impact on the electronic component 50 and prevent the electronic component 50 from overflowing from the outlet 6.

In addition, the holding portion 300 may be provided on the wall portion 241 in a horizontally extending state with the side wall portion 302 and the side wall portion 303 as shown in FIG14. In this case, as shown in FIG14, the side wall portion 303 provided with the upper hook portion 251, the lower hook portion 252 and the opening and closing mechanism 260 is disposed on the upper side, and the side wall portion 302 is disposed on the lower side. A groove-shaped member 306 may be provided in the discharge portion 230 so as to supply the electronic component 50 dropped from the turntable 212 to the inside of the cylindrical member 231 so that the electronic component 50 is accommodated in the housing 1. In this way, when the housing 1 is placed horizontally, the inclined surface 7a is arranged at the top, and the electronic components 50 to be accommodated are accommodated so as to be retained on the inner side of the top plate portion 2U of the housing 1.

Although the implementation forms have been described above, the present invention is not limited to such implementation forms, and changes and improvements within the scope that can achieve the purpose of the present invention are included in the present invention.

For example, instead of arranging the housing 1 vertically, it can be arranged horizontally as shown in FIG. 1 , and the electronic component 50 falling from the discharge portion 230 by its own weight can be received in the housing 1 from the discharge port 6 .
