Description

[Detailed description of the invention] This invention allows a predetermined number of piston rings to be suspended from a pair of chute and continuously fed along the chute using their own weight from one piston ring processing device. The present invention relates to a piston ring constant separation and supply device that intermittently supplies piston rings to a piston ring processing device for the next processing step.

According to this invention, a stopper is provided on one side, and the movement of the piston ring that is fed along the pair of shoots is stopped by the stopper, and a brake shoe is provided on the other side. When the user holds the piston ring and raises the stopper, a predetermined number of piston rings located between the stopper and the brake shoe are supplied to the next processing device, and the stopper is lowered and the brake shoe removes the piston rings. A piston ring constant separation and supply device is provided which arranges a predetermined number of piston rings between the times when the clamp is released, and an embodiment of this invention will be described with reference to the accompanying drawings.

The piston ring 1 has a pair of chutes 2 and 3 arranged to be inclined downward so that the piston ring 1 can be moved by its own weight. The pair of chute 2, 3 are spaced apart, each chute 2, 3 is provided with a passage 4, and a guide plate 5 is provided between the pair of chute 2, 3.
will be arranged. The guide plate 5 extends vertically through the abutment of the piston ring 1, and when the piston ring 1 is about to rotate clockwise, for example, when the piston ring is being supplied, the abutment passes through the guide plate 5. The rotational movement of the hit is regulated. Therefore, the portion of the piston ring 1 near the abutment always enters the passage 4, and the piston ring 1 can be suspended in the correct posture relative to the chute 2, 3. A piston ring constant separation and supply device 6 is disposed at a suitable location on the conveyance path of the piston ring 1.

The piston ring constant separation and supply device 6 has an upper substrate 7 and a lower substrate 8 which are spaced apart from each other.
are connected by a centrally located central block 9 and fixed to a stationary member. Furthermore, both substrates 7 and 8 are connected by a supply block 10 and a delivery block 11. Block 9, 10, 1
1 has the same thickness as the guide plate 5;
It is arranged so that it is on the same plane as the A slider 12 is slidably disposed between the supply block 10 and the central block 9. The slider 12 has upper and lower parts 13 that move up and down along the inner walls of the paired chute 2 and 3.
14 and a web 15 between them. web 1
5 is on the same plane as the supply block 10 and the central block 9. A pair of lower brake shoes 17 are fixed to the lower end portion 16 of the slider 12, and a pair of upper brake shoes 18 and lower brake shoes 17 are attached to opposing shoots 2 and 3, so that they are normally spaced apart from each other. Allotted. The top surface of the upper portion 13 of the slider 12 and the lower surface of the upper substrate 7 are spaced apart from each other to allow the slider 12 to move up and down. A spring 21 is interposed between the upper end of the rod 19 and the plate 20. When the plate 20 is moved upward by a drive device (not shown), the slider 12 rises while receiving the urging force of the spring 21, the lower brake shoe 17 approaches the upper brake shoe 18, and the piston between the two moves. Ring 1 is clamped and its movement is restricted. At this time, the spring 21 prevents the piston ring 1 from being clamped more strongly than necessary and being damaged by the brake shoes 17 and 18.

A stopper 22 is arranged between the delivery block 11 and the central block 9. The stopper 22 is a guide piece 2 having the same thickness and the same plane as the central block 9.
3 and a stopper surface 24 perpendicular to the guide piece 23. Normally, the stopper surface 24 has a lower portion located below the passage 4 of the chute 2, 3, and the piston ring 1 moves along the passage 4 under its own weight.
and stops the movement of piston ring 1. The upper part of the stopper 22 is spaced apart from the upper substrate 7, and a rod 25 fixed to the upper part passes through the upper substrate 7, extends upward, and is fixed to the plate 20. plate 20
When moved upward by a drive device (not shown),
The stopper 22 rises along the side edge of the central block 9, and the lower end of the stopper surface 24 moves above the passage 4 of the chute 2, 3, freeing the movement of the piston ring 1 and sending it out by its own weight. . At this time, the slider 12 also rises and the piston ring 1 is held between the brake shoes 17 and 18, so that the movement of the piston ring 1 in this portion is restricted. When the plate 20 is lowered again and the lower part of the stopper surface 24 is below the passage 4 of the chute 2, 3, the brake shoe 17, 1
8 is released, the piston ring 1 from the supply side moves toward the stopper surface 24, and the stopper surface 24 and the slider 1
A predetermined number of piston rings 1 are arranged between the piston rings 1 and 2.

The guide plate 5 is replaced with the supply side and delivery side blocks 10 and 11 by the slider 12 and the stopper 22.
It may be made to come into contact with. It is preferable to provide a piston ring attitude control device using a lever or the like below the stopper 22.

As is clear from the above, in this invention, a predetermined number of piston rings are arranged between the vertically movable stopper and the slider, and when the lower part of the stopper surface of the stopper is located above the chute passage, the slider When the brake shoe applies braking force to the piston ring between both brake shoes, and only the piston ring between the stopper surface and the slider is delivered, and the lower part of the stopper surface is located below the chute passage, the brake shoe With a simple configuration in which power is released, a predetermined number of piston rings can be delivered at all times. That is, by pinching the piston ring between the two brake shoes, the piston ring can be braked more reliably. Also, the spring cooperating with the slider provides proper braking force to the piston ring and prevents it from being damaged by the brake shoe.
