The electronic component 50 is pushed by the subsequent electronic component 50 and is continuously transported toward the discharge unit 230 on the vibrating transport unit 211 .

The non-vibration conveying unit 220 is disposed between the vibrating conveying unit 211 and the discharge unit 230 . The electronic component 50 conveyed on the vibration conveyance part 211 is transferred to the non-vibration conveyance part 220 . As shown in FIG. 6 , three partitions 221 are provided at intervals from the upstream side to the downstream side on the upper surface of the non-vibration conveyance part 220 on which the electronic component 50 is transferred. Each of the partitions 221 blocks or opens the space above the non-vibrating conveying part 220 , that is, the path of the electronic component 50 by moving up and down or reciprocating sideways by an actuator not shown. FIG. 6 shows a state in which the electronic components 50 are stopped by the partitions 221 that block the passage on the non-vibration conveying portion 220 .

When the partition part 221 blocks the passage on the non-vibration conveyance part 220, the conveyance of the electronic component 50 is stopped by the partition part 221. One electronic component 50 that has stopped is detected by the conveyance component detection part 279 provided in parallel at the side of the non-vibration conveyance part 220 . The conveyed component detection unit 279 includes three component detection units corresponding to the three partitions 221 , that is, the first component detection unit 271 , the second component detection unit 272 , and the third component detection unit 273 .

The electronic component 50 passing through the drop hole 215 falls to the inside of the upper tube 233 , reaches the inside of the lower tube 234 , passes through the inside of the lower tube 234 , and falls. The electronic component 50 may slide down while being in contact with the inner surface 232 of the cylindrical member 231 .

In order to suppress electrical damage to the electronic component 50 due to static electricity generated by friction, it is preferable that at least the inner surface 232 of the cylindrical member 231 is made of a material containing a conductive material such as a conductive metal. Furthermore, it is preferable that the inner surface 232 of the cylindrical member 231 is a smooth low-friction surface so that the electronic component 50 can slide down smoothly. For example, it is preferable to process the surface on resin such as fluororesin.

The ejection part 230 is provided with a pressing pin 236 for forcibly dropping the electronic component 50 from the drop hole 215 . The pressing pin 236 is disposed above the drop hole 215 matching the passing hole 218 . The pressing pin 236 is a rod-shaped member extending in the vertical direction, and is driven in the vertical direction by an actuator (not shown) or the like. When the pressing pin 236 is driven downward, the electronic component 50 in the drop hole 215 is pressed downward and falls into the inside of the cylindrical member 231 . By pressing with the pressing pin 236 , the electronic component 50 is surely dropped from the drop hole 215 without being caught in the drop hole 215 .

Furthermore, an air flow generating portion 237 for dropping the electronic component 50 from the drop hole 215 by the flow of air may be provided in the discharge portion 230 instead of the pressing pin 236 or additionally. As such an airflow generator 237 , for example, one having a function of blowing air onto the electronic component 50 from above to drop it, or sucking air from the side to drop the electronic component 50 can be mentioned.

By sucking in the air through the cleaning part 238 , the inside of the drop hole 215 and the cylindrical member 231 , that is, the air of the path of the electronic component 50 is sucked. Thereby, debris, dust, and the like existing in the path are sucked into the cleaning unit 238 and cleaned. Furthermore, the cleaning part 238 can also be used to clean the path of the electronic component 50 by blowing out air and blowing away debris or dust. In this case, in order to prevent fragments or dust from entering the box body 1 , the door member 3 can be used to close the discharge port 6 .

The bottom plate portion 2D of the box body 1 is parallel to and opposite to the wall surface 241a with a gap.

In the wall portion 241, a recess 242 extending in the vertical direction and opening toward the wall surface 241a side is formed. Inside the recess 242, an opening and closing mechanism 260 for sliding the door member 3 is disposed. The opening and closing mechanism 260 has a drive pin 261 provided movably in the vertical direction along the bottom surface of the recess 242 . The front end of the driving pin 261 protrudes from the wall surface 241a. The driving pin 261 is vertically movably supported, for example, along a guide groove provided on the bottom surface of the recess 242, and is reciprocally driven vertically by an actuator or the like. In the recess 242 of the wall part 241, the reader-writer 243 which reads and writes information with respect to the RFID tag 5 non-contact is arrange|positioned. The reader/writer 243 is an example of the information read/write unit. Furthermore, the upper hook portion 251 and the lower hook portion 252 may not have the same shape.

On the other hand, the driving pin 261 moves upward. When the driving pin 261 is positioned upward, if the case body 1 with the discharge port 6 blocked by the door member 3 is held in the holding portion 250, the driving pin 261 is inserted into the lower opening 4c of the slider 4 shown in FIG. It is positioned between the front end plate portion 4d and the rear end plate portion 4e.

When the driving pin 261 is moved downward from this state in FIG. 9 , the driving pin 261 comes into contact with the rear end plate portion 4 e of the slider 4 , and the slider 4 is pressed downward and slides. As the slider 4 slides downward, the door blocking member 3 slides behind the box body 1 . In this way, as shown in FIG. 10, the protrusion 4b of the slider 4 fits into the recess 26b on the rear side, and the opening 3a of the door blocking member 3 coincides with the discharge port 6 of the box body 1, and the discharge port 6 opens. When the driving pin 261 returns upward from this state, the driving pin 261 comes into contact with the front end plate portion 4d of the slider 4, and the slider 4 is pushed upward and slides. As the slider 4 slides upward, the door blocking member 3 slides to the front of the box body 1 , as shown in FIG.

During the conveyance of the non-vibration conveyance part 220, the conveyance number of the electronic component 50 is counted by the 1st component detection part 271. In addition, the number of electronic components 50 dropped from the drop hole 215 and finally housed in the case 1 is counted by the fourth component detection unit 274 including the upstream passage detection unit 275 and the downstream passage detection unit 276 . When the number of electronic parts 50 accommodated in each box body 1 reaches a specified number, the conveyance of the electronic parts 50 by the conveying part 210 is interrupted, and after the setting part 240 is replaced with a new empty box body 1, the delivery of the electronic parts 50 to the box body 1 is resumed. Electronic components 50 are accommodated. Furthermore, in the above-mentioned continuous operation of the plurality of conveying lines, that is, the first conveying line 210A, the second conveying line 210B, and the third conveying line 210C, it is desirable to control each line independently, but it is also possible to control the plural conveying lines synchronously. action.

In the parts storage device 200 of the embodiment, when the cassette body 1 is set in the installation part 240, various information can be written on the RFID tag 5 of the cassette body 1 by the reader-writer 243.
