Description

[Detailed description of the invention] Industrial application field The present invention supplies a button fastening part such as a rivet having two claws spaced apart from each other on one side of the base from a hopper to a chute while maintaining it in a predetermined direction. This invention relates to a button stopper supply device.

BACKGROUND TECHNOLOGY A device for supplying a button stopper having two claws spaced apart from each other on one side of a base consists of a hopper provided with a pick-up plate for the part, and the pick-up plate is used to pick up the part. It is known to have an upwardly opened inclined guideway at the upper edge of the base to accommodate the base, and to feed the component into the chute while rotating it along the base surface of the inclined guideway.

In this type of device, the rotational state of each of the parts fed from the hopper to the chute is not uniform (that is, both claws are not located parallel to the part transfer direction), and the claws of the parts are Since the claw guide path of the chute for receiving and guiding the chute is relatively wide, the parts sliding in the chute also fall onto the transport table in various rotational states. As a result, in order to supply a button stopper having two claws with a directional pattern etc. to the die in a predetermined rotation state, a wavy edge is used as disclosed in Japanese Patent Application Laid-Open No. 52-13943. A pair of guide blocks having a plurality of sections are elastically attached by a compression spring in a parallel and spaced state, and a meandering conveyance passage (labyrinth passage) whose width gradually becomes narrower toward the die is provided.

Problems to be Solved by the Invention As described above, in this type of button stopper supply device, the button stopper is delivered to the chute while rotating within the inclined guide path of the pick-up plate. It is necessary to provide the above-mentioned labyrinth mechanism on the table, and therefore there is a problem that many structural members are required and the structure becomes complicated.

Therefore, the present invention makes it possible to supply the button stopper to the chute while maintaining it in a predetermined direction by skillfully utilizing the two claws of the lead stopper to prevent the part from rotating. The object of the present invention is to provide a parts supply device for button fastening parts.

Means for Solving the Problems In order to solve the above problems, in the button stopper supplying device according to the present invention, the upper edge of the pick-up plate provided in the hopper has an inclined upper edge that is inclined in the chute direction. a flange portion is formed by cutting out the rear cover side along the upper edge, and between the flange portion and the rear cover side,
A guide path for accommodating the base of the component is formed, and the height of the flange is at least equal to a straight line connecting one side of both claws of the component and a peripheral surface of the one side of the base of the component. It is larger than the distance to the tangent.

Embodiments Hereinafter, the present invention will be explained based on embodiments shown in the drawings.

Fig. 1 shows a fixing part A such as a rivet having two claws spaced apart on one side of the base, which is maintained in a predetermined direction and fed to a die (not shown) with the claws facing upward. The figure shows a stopper supply device for the purpose.
The parts supply device includes a hopper 1 and a hopper 1.
It consists of a chute 2 for sliding down the stopper part A supplied from the chute 2, and a conveyance table 3 for receiving the stopper part A that has fallen from the chute 2 and transferring it to the die. The chute 2 and the transport table 3 are provided with claw guide paths 4 and 5 for slidingly guiding both sides of each claw of the stopper part A during transport. The pawl guide path 4 of the chute 2 is
The upper part is curved in an arc toward the hopper 1,
A lower portion is curved in an arc toward the die.
Note that reference numeral 6 indicates a pusher that engages with the base of the stopping part A that has fallen onto the conveyance table 3 and pushes the part A toward the die.

As shown in FIG. 2, the hopper 1 includes a parts tray 9 that forms a hopper bottom that is inclined toward the rear cover 7 side and is also inclined toward the outer cover 8 side, and the rear cover 7 and the parts tray 9. A pick-up plate 10 is disposed between the hopper 1 and the pick-up plate 10 for picking up the stopper part A in the hopper 1. The pick-up plate 10 can be slid up and down along the lower leg portion 9a of the parts tray 9 via an arm 11 connected to a drive lever (not shown). 12 is the lowest corner of the parts tray 9.

The pick-up plate 10 is arranged between the outer cover 8 and the inner cover 1 adjacent to the chute 2.
3, the upper edge thereof has an inclined upper edge surface 14 inclined in the direction of the chute 2, and the rear cover 7 side is notched to the same depth along the upper edge surface 14. A flange portion 15 is formed.
In this way, as shown in FIGS. 2 and 3, an inclined guide path 17 having a base surface 16 parallel to the inclined upper edge surface 14 is provided between the flange portion 15 and the rear cover 7. is formed. Furthermore, as shown in FIG. 4, the height h of the flange portion 15 is defined by at least a straight line connecting one side (lower side) of both claw portions of the component A and the lower side of the base of the component A. It is larger than the distance d from the tangent on the peripheral surface. With such a configuration, the stopper part A picked up by the pick-up plate 10
slides toward the chute 2 with the lower sides of both claws in contact with the inclined upper edge surface 14 and the lower peripheral surface of the base separated from the base surface 16.

Next, the operation of the parts supply device according to the present invention will be explained.

First, by actuating a drive lever (not shown),
The pick-up plate 10 is lowered until the highest part of its inclined upper edge surface 14 reaches the position of the lowest corner part 12 of the parts tray 9, and the base of the stopper part A is accommodated in the inclined guide path 17. Then, pick up a plurality of stop parts A. As the pick-up plate 10 rises, the stopper A picked up in this way is brought into contact with the lower side of the base end of both claws and the inclined upper edge surface 14, and the lower peripheral surface of the base is brought into contact with the inclined guide. By sliding along said sloping upper edge surface 14 away from the base surface 16 of channel 17 , the most distal end stop part A engages said inner cover 13 .
reach. When the pick-up plate 10 is raised further, the stop part A falls into the chute 2 through a feed opening (not shown) formed in the inner cover 13 to the chute 2. At this time, both claws of the component A slide into the claw guide path 4 of the chute 2 from the inclined upper edge surface 14 in a state parallel to the component transfer direction. Next, the part A
is rotated gradually as both sides of each claw are guided along the upper curved portion of the claw guide path 4, and then maintained in a constant direction by the straight portion of the claw guide path 4. It reaches the lower part of the chute 2.
In the lower part of the chute 2, the part A is guided with both sides of each claw part along the downward curved part of the claw part guide path 4, rotates gradually again, and then falls onto the conveying table 3. Finally, the part A is supplied to a die (not shown) while being maintained in a predetermined direction with both sides of each claw being guided by the claw guide path 5 of the conveying table 3.

Effects of the invention As described above, according to the invention, the rear cover of the hopper exists within the range in which the pick-up plate moves up and down, and the component has two claws, so the base of the component is always located within the rear cover. and the above-mentioned pick-up plate, and both claws are easily arranged on the upper edge surface of the flange portion. As a result, if there is a directional pattern, etc. on the surface of a part, the direction of the pattern, etc. will be constant, and therefore a device that rotates the part by a predetermined angle to make the pattern, etc. face in a certain direction is required. It will be simple.
