The chip resistor R is not a good chip resistor. If it is mixed in the resistor R, it will cause supply trouble, so it will be automatically discharged when supplying. There is a need to.

[0009] Next, the automatic feeding device of the present invention will be explained. Figures 1 to 5 show an automatic supply device for chip-shaped workpieces according to an embodiment of the present invention. Fig. 1 is a partially cutaway plan view of the main part, Fig. 2 is a partially cutaway side view of the main part, and Fig. 3 is a partially cutaway side view of the main part. The A-A arrow view in Fig. 1, and Figs. 4(a) and (b) show the removal of chipped chip-like workpieces, respectively. A partially cutaway plan view for explaining the ejecting operation, Figures 5(a) and (b) are each a broken chip. FIG. 3 is a partially cutaway plan view for explaining the ejection operation of a shaped workpiece.

0010 As shown in Figures 1 to 3, the disk 1 is centered around a vertical rotation axis (not shown). It is rotatably supported. The disk 1 has an annular protrusion 2 formed on the upper outer periphery. A large number of storage grooves 3, which are supplied portions, are formed at equal intervals in this protruding portion 2, and each storage groove 3 is formed at equal intervals. A vertical suction hole 4 is formed in the center of the bottom of the groove 3. Disk 1 is a drive device ( (not shown) intermittently rotates in the direction of arrow X.

[0011] In order to sequentially supply the chip resistors R to each storage groove 3 of the disk 1, A supply path 5 for linearly transporting R is provided. That is, the pair of guide members 6 , 7 and a top plate 8, a supply path 5 is formed. In this supply route 5 The chip resistor R is continuously supplied by a linear feeder (not shown). Supplement A part of the side wall of the supply path 5 at a position closer to the disc 1 side is constituted by a discharge gate 9, This discharge gate 9 is operated by a transmission mechanism (not shown) driven by a solenoid (not shown). The opening is closed at the solid line position in FIG. 1 and opened at the chain line position in FIG. discharge The gate 9 is set to be slightly wider than the length of the chip resistor R.

0012 A stopper 10 is provided on the side of the disk 1, and this stopper 10 closes the supply path. positioning the chip resistor R supplied from 5 to the storage groove 3 at a predetermined position; I can do it. The chip resistor R stored in the storage groove 3 is supplied as the disk 1 rotates. When the passage 5 is transferred slightly downstream in the rotational direction, the suction device ( (not shown) and held in the storage groove 3.

[0013] Above the tip of the stopper 10, there is a stopper 10 and a hole that can be properly supplied to the supply groove 3. A fiber sensor 11 is installed so as to straddle both the chip resistor R and the chip resistor R. The rear end of the fiber sensor 11 faces the emitter and receiver (not shown). . Then, the light is emitted from the light emitter via the fiber sensor 11, and the reflected light is sent to the optical fiber. The light is received by a light receiver via the sensor 11. At this time, the stopper 10 and the chip resistor If the reflection from both resistors R indicates that the supply condition of the chip resistor R to the storage groove 3 is good, If it is reflected only from the stopper 10, the chip resistor R against the storage groove 3 supply condition is poor, or the chip resistor R supplied to the storage groove 3 is missing. It is possible to detect that the The top plate 7 has holes 12 corresponding to the supply passages 5. is formed, and a fiber sensor 13 is provided above the hole 12. The rear end of 13 faces an emitter and a light receiver (not shown). These holes 12 and The base sensor 13 is directly connected to the discharge gate 9 in the transfer direction of the chip resistor R. When the chip resistor R located in front and the chip resistor R in front of it are normal It is set in such a position that it straddles them. Then, connect the fiber from the emitter. The light is emitted through the fiber sensor 13, and the reflected light is received by the light receiver through the fiber sensor 13. Ru. At this time, if it is reflected from both the chip resistors R that follow before and after, the discharge gate There is no crack in the chip resistor R located right in front of the chip resistor R, and there is only one chip resistor R. There is a crack in the chip resistor R located just before the discharge gate 9. can be detected.

[0014] On the disk 1, air is directed toward the chip resistor R supplied to the storage groove 3. An air ejection pipe 14 is provided for ejecting air, and an air ejection pipe 14 is provided on the guide member 6 and positioned at the discharge gate 9. Air is ejected from the side toward the discharge gate 9 side against the chip resistor R that is placed. An air jet pipe 15 is provided for this purpose. The other end of each air jet pipe 14, 15 is It is connected to a compressor (not shown). The sole that opens and closes the above discharge gate 9 The noid and the compressor are detected by a detection means using fiber sensors 11, 13, etc. It is designed to be driven by results.

[0015] The operation of the above configuration will be described below. As shown in FIGS. 1 and 2, the chip resistor R is placed in the supply path 5 by a linear feeder. is continuously supplied and transported linearly within the supply path 5. Meanwhile, disk 1 is rotated intermittently. Then, the arbitrary storage groove 3 is stopped facing the supply path 5. This will cause the first The chip resistor R is pushed by the rear chip resistor R and stored in the storage groove 3. Then, it comes into contact with the stopper 10 and its position is regulated. After regulating the position, rotate disk 1 intermittently. When the next storage groove 3 is placed opposite the supply path 5, a chip is inserted into this storage groove 3 in the same way as above. The chip resistor R in the storage groove 3 is inserted through the suction hole 4. and is held in the storage groove 3 by a suction device. During this time, use the fiber sensor 11, etc. The detection means detected indicates that the supply condition of the chip resistor R to the storage groove 3 is good. , detects that there is no chipping in the chip resistor R, and also detects the fiber sensor 13 etc. When the detection means used detects that there is no crack in the chip resistor R, the above operation is performed. By repeating the process, chip resistors R are sequentially supplied to the storage groove 3 of the disk 1, processed and inspected. It can be transported for etc.

If so, this is detected by a detection means using a fiber sensor 11 or the like, Stop the drive of the linear feeder (use air to assist in supplying the chip resistor R) If used, the drive of this supply auxiliary means is also stopped. ),solenoid As shown in FIG. 4(b), the discharge gate 9 is opened. Along with this, The presser is driven to blow out air from the air blowing pipes 14 and 15, respectively. child Accordingly, first, the chip resistor R located at the discharge gate 9 is connected to the supply path 5. Eject the chip resistor R to the outside through the open part of the side wall, and then put the chip resistor R into the storage groove 3. from the supply path 5 and forcibly discharged to the outside from the open part of the side wall in the supply path 5. put out Therefore, it is possible to prevent supply problems from occurring. Ru.

[0017] In addition, as shown in FIG. 5(a), the chip resistor R supplied to the supply path 5 If this is the case, this is detected by a detection means using a fiber sensor 13 or the like. , when the broken chip resistor R is transferred to the position of the discharge gate 9, the linear feeder (If using an auxiliary means for supplying the chip resistor R using air) In this case, the drive of this supply auxiliary means is also stopped. ), by driving a solenoid. As shown in FIG. 5(b), the discharge gate 9 is opened. Along with this, the compressor is to blow out air from the air blowing pipe 15. Along with this, the position at discharge gate 9 has been increased. Place the cracked chip resistor R to the outside through the open part of the side wall of the supply path 5. Forcibly eject. Therefore, prevent supply problems from occurring. be able to. Note that the opening and closing of the air jet pipes 14 and 15 is controlled by one valve. In such a case, air jets from the air jet pipes 14 and 15 may cause chips inside the storage groove 3 to The resistor R can be moved back diagonally and discharged to the outside through the opening in the side wall. .

[0018] Also, if a chip resistor R with a defective shape etc. gets mixed in and ends up in the storage groove 3 of the disk 1, 4(a) and 4(b), even if a portion remains on the supply path 5 side. This chip-shaped resistor R is detected by a detection means using a fiber sensor 11 or the like. Then, the drive of the linear feeder etc. is stopped, the discharge gate 11 etc. is opened, and the air jet pipe 14 is opened. , 15, and the chip resistor R at the position of the discharge gate 9 and the supply. Remove the chip resistor R that is causing the trouble from the open part of the side wall of the supply path 5. be forcibly discharged to the outside. Therefore, we can prevent supply problems from occurring. can be prevented.

[0019] In the above embodiment, storage units formed at equal intervals on the outer periphery of the disk 1 serve as the supplied parts. Although the case where groove 3 does not have a back wall has been explained, it is also carried out when it has a back wall. In this case, the stopper 10 is not required. In addition, there is a storage groove 3 in the disc 1. It can be applied not only to the case of forming a line but also to the case of transferring it in a straight line. Book The invention may be subject to various other design changes without departing from its basic technical concept. I can do it.
