【Example】

 A first embodiment of the present invention will be described below with reference to the drawings. As shown in FIG. 1, the stacking device includes a base 13, a hopper 1, a supply tray 2, a guide body 3, pins 4 as receiving members, sensors 5a and 5b, a vibrator 8 and the like.

As shown in FIG. 1, a metal back plate 10 is provided at one end of a metal plate-shaped base 13 so as to stand slightly obliquely toward the inside of the base 13. On the other hand, on the table 13, on the opposite side of the back plate 10 is provided a case 15 whose front and upper surfaces are open.

A funnel-shaped guide body 3 is provided at the upper opening of the case 15. The inner diameter of the cylinder 3a provided at the lower end of the guide body 3 is set to be the same as or slightly larger than the outer diameter of the gasket 12 as a ring-shaped member.

On the table 13, a block 4 a having pins 4 standing upright is placed directly below the cylinder 3 a of the guide body 3. That is, the pin 4 is arranged so that the axis of the pin 4 and the axis of the tube 3a of the guide body 3 are the same. The outer diameter of the pin 4 is slightly smaller than the diameter of the hole provided at the center of the gasket 12. Therefore, the gasket 12 can be inserted into the pin 4. Further, the tip of the pin 4 is provided so as to be thinner toward the tip so that the gasket 12 can be easily inserted.

A light projecting sensor 5a and a light receiving sensor 5b are provided so as to face each other on inner surfaces of the case 15 which face each other. The height of both the sensors 5a and 5b is H shown in FIG. 1, that is, the height from the base 13 to the substantially tip of the pin 4 is provided. Further, as shown in FIG. 2, the light projected from the light projecting sensor 5a is provided so as to pass inside the outer circumference of the gasket 12 outside the outer circumference of the pin 4.

A supply tray 2 having a low friction coefficient is provided between the upper end of the back plate 10 and the upper end of the case 15. The bottom plate 16 of the supply tray 2 is provided so as to be lower on the case 15 side than the upper end of the back plate 10. The pair of partition pieces 2a of the supply tray 2 are provided so as to gradually become thinner from the upper end of the back plate 10 to the upper end of the case 15. The space between the partition pieces 2a is set to be slightly larger than the outer diameter of the gasket 12. Corresponding to the tip of the partition piece 2a, the bottom plate 16 is provided with a guide tongue piece 11 extending obliquely downward for guiding the gasket 12 to the tube 3a of the guide body 3.

A hopper 1 is provided at the upper end of the back plate 10 so that its length direction is horizontal. That is, both sides of the hopper 1 are supported and fixed. One side surface 1a of the hopper 1 projects above the supply tray 2, and a discharge port 9 through which the gasket 12 discharges is provided at the lower end of the side surface 1a.

A vibrator 8 is attached to the back side of the bottom plate 16 of the supply tray 2 near the case 15 so that the supply tray 2 and the hopper 1 are horizontally vibrated.

A control box 14 is provided on the table 13. The control box 14 contains a control circuit including a delay timer. Further, a buzzer 7 is provided on one side surface of the box 14. A switch 6 for turning on / off a control circuit and the like is provided on the box 14.

The control circuit including the delay timer performs a detection operation by the delay timer when the light projected onto the light projecting sensor 5a and the light receiving sensor 5b is temporarily blocked by the falling gasket 12. It is supposed not to do. Further, when the laminated gasket reaches a predetermined height, the light emitted from the light emitting sensor 5a is always blocked, so that the detection operation is performed.

Next, the operation of the present invention configured as described above will be described. When the switch 6 is turned on, the vibrator 8 and both sensors 5a and 5b start operating. That is, light is emitted from the light projecting sensor 5a toward the light receiving sensor 5b. Further, when the vibrator 8 starts operating, the supply tray 2 and the hopper 1 vibrate in the horizontal direction. As a result, the gaskets 12 pop out from the hopper 1 one by one onto the supply tray 2. Then, slide on the supply tray 2 in the direction of the guide body 3. Then, as the distance between the pair of partition pieces 2a becomes narrower as it approaches the guide body 3, when the gasket 12 falls onto the guide body 3, each gasket 12 regularly falls on the guide tongue piece 11 and falls onto the guide body 3.

The gasket 12 that has fallen onto the guide body 3 falls through the tube 3 a from the tip of the pin 4 and is inserted into the pin 4. When the gasket 12 is inserted into the pin 4 and falls toward the base 13, the gasket 12 temporarily blocks the light projected from the light projecting sensor 5a. However, the delay timer does not start the detection operation because the light was only temporarily blocked.

By repeating the above, the gasket 12 is inserted into the pin 4 and laminated. When the gaskets 12 are stacked up to the height H, the light receiving sensor 5b is always prevented from receiving the light projected from the light projecting sensor 5a. Therefore, the sensor detects that the light is blocked. The delay timer starts the detection operation based on this detection result. That is, the delay timer starts counting time. Then, when counting the preset time, the control circuit outputs a control signal to the vibrator 8 and the buzzer 7. Then, based on this signal, the vibrator 8 stops operating and the buzzer 7 sounds.

Therefore, according to the embodiment of the present invention, unlike the prior art, there is an excellent effect that the gasket 12 can be automatically laminated on the pin 4. The present invention is not limited to the above embodiment, but may be as follows, for example. That is, in the above-described embodiment, the surface of the base 13 on which the pins 4 are erected, that is, the bottom surface of the case 15 may be concave so that the missing gaskets 12 are naturally gathered at one place. .

Further, the gasket 12 may be automatically supplied to the supply tray 2, and the vibrator 8 may vibrate only the supply tray 2. Also, any changes may be made without departing from the spirit of the invention.
