A funnel-shaped hopper 3 for storing parts is arranged at the outlet of this guide member 43. It is fixed to the machine base 1 by a frame 2. Right below the outlet of hopper 3 is equipped with a vibrating supply chute 11 that transports parts falling from the hopper 3 forward. The front chute surface of this supply chute 11 is Alignment grooves 11a having an acute-angled cross section, for example, a triangular shape, are formed (FIG. 3). this supply The chute 11 is attached to the first vibrating part 12, and the first vibrating part 12 is supported by the machine base 1. It is attached to a support stand 4 which is provided with Directly below the tip of the supply chute 11 is a A loosening chute 21 is arranged so that the rear parts overlap, and this loosening chute The mute 21 is supported by a second vibrating section 22 and attached to the machine base 1. This loosening As shown in Fig. 2, the chutes 21 are arranged in two rows in parallel. A micro-volume chute 31 for supplying parts in small quantities is provided in parallel between the holes 21. This minute chute 31 is configured to be driven by a third vibrating section 32.

[0007] On the other hand, as shown in FIG. At the rear of the loosening chute 21, there is a substantially horizontal apex angle of the triangular alignment groove 11a. so that the ridgeline of the mountain is located below (that is, the alignment groove 11a of the supply chute 11 is A triangular cross-section (with ridgelines at positions that distribute the moving parts to both sides) It has a feed groove 21a. Continuing with and in front of this alignment groove 21a, the alignment groove 21a is The feed groove 23a has a shape in which the ridgeline of the mountain is located on an extension of the bottom apex angle of the feed groove 21a. In addition, there is an inclined chute section 23 slightly inclined forward and a tip of this inclined chute section 23. A deceleration shoe having an alignment groove 24a that is slightly inclined in the opposite direction and has the same shape. 24 is formed continuously. The front end of this deceleration chute section 24 has a is inclined downward and has a feed groove (not shown) having the same shape as the inclined chute portion 23. An auxiliary chute 33 having a The angle is set at such an angle that the parts that jump out from the seat part 24 and fall can slide down. child The tip of the auxiliary chute 33 is a packaging machine in which sliding parts are placed below the machine.

This imager 53 detects the auxiliary shoes within the effective range L. The number of parts falling from the tip of the tray 33 is counted.

[0009] Next, the operation of this embodiment will be explained. When the counting machine starts operating, the parts supplied to the bucket 42 of the parts input means 40 8 (for example, a threaded part) is conveyed upward by the lifting mechanism 41, and the guide member 43 into the hopper 3. After charging, the bucket 42 descends. screw parts The parts loading means 40 operates repeatedly until the parts 8 are sufficiently stored in the hopper 3. hopper The screw parts 8 stored in the hopper 3 are fed through the supply shoe from the outlet of the hopper 3, which is opened appropriately. Continuously slides down to 11. At the same time, the first vibrating section 12 operates, and the supply shoe The bolt 11 vibrates and the screw part 8 moves forward. Also, it is placed in front of this The second vibrating part 22 starts operating at the same time, and the screw part moving on the supply chute 11 The product 8 falls onto the loosening chute 21 from the alignment groove 11a at the tip as shown in FIG. Ru. At this time, the threaded part 8 is loosened by the triangular alignment groove 11a of the supply chute 11. The triangular top (ridgeline of the mountain) of the chute 21 overlaps the bottom of the alignment groove 11a. At this point, the threaded parts 8 are transferred to the alignment grooves 21a on both sides of the loosening chute 21. Separate yourselves appropriately. The screw parts 8 that are separated and fed forward in this way gradually separate from each other. The overlap between the two is loosened. This threaded part 8 is then tilted forward as shown in FIG. Moving to the chute part 23, the screw parts 8 are separated from each other, so the loosening chute The overlapping screw parts on 21 are removed and dispersed, and the deceleration chute 24 Then, it moves to the alignment groove of the auxiliary chute 33. In this way, it enters the alignment groove of the auxiliary chute 33. The screwed part 8 that has been removed falls along the slope of the auxiliary chute 33. fall at this time Since the screw part 8 is guided to the auxiliary chute 33 as shown in Fig. 5, there is no variation in the falling trajectory. The drop is small and falls in an almost constant trajectory. In this way, the effectiveness of the imager 53 is The screw part 8 falling from the tip of the auxiliary chute 33 within the counting width L is the light source 5 1 and the imager 53. The imager 53 detects the brightness of this light and The number of screw parts 8 falling from the tip of the auxiliary chute 33 is counted based on the signal. Then, the approach value A is set to a smaller number than the preset specified number B. Once reached, the supply chute 11 and the loosening chute 21 stop, and a small amount of shred is removed. Since only port 31 continues to operate, it will take a short time until the specified number B is reached. The number of pieces is supplied by a small amount chute 31. It is counted in this way and reaches the specified number B. Then, the supply of screw parts 8 from the minute chute 31 is stopped, and at the same time The shutter (not shown) closes. As a result, the screw part 8 is packed below this counting machine. By arranging the bags or boxes, the specified number B of screw parts 8 will be thrown in. Therefore, an accurate number of screw parts 8 can be packaged. Next, prepare the next bag or box. After that, the shutter opens and the vibrating parts 12, 22, and 32 operate, and the screw part 8 is rotated again. It is possible to accurately supply a predetermined amount by counting the amount.
