Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a device for separating and conveying coil springs that are continuously supplied in a continuous contact state by a parts feeder or the like.

(Prior art) Conventionally, as shown in Japanese Utility Model Application Publication No. 59-149824,
A separating and conveying device that separates coil springs supplied in one row one by one is known.

(Problems to be Solved by the Invention) However, a slide deck is used to transport the separated coil springs, and this slide deck is driven by an air cylinder rod.

In addition, since the jaw is opened and closed by an air cylinder in order to grip the coil spring, the structure is complicated and expensive.

(Means for solving the problem) In order to solve the above-mentioned problem, the present invention aims to reduce the distance between the lower end position of the coil spring supply chute where the coil springs are continuously dropped in one line and the position of the coil spring take-out chuck placed at a predetermined position. A swing arm is disposed to swing, and a support rod is protruded from the tip of the swing arm to be inserted into the lowest coil spring in the coil spring supply chute and supports the coil spring. The rod is shorter than the length of the coil spring, and when the support rod stops at the lower end of the coil spring supply chute, it is located coaxially opposite to the lower end of the coil spring supply chute and moves in the axial direction of the coil spring supply chute when rotated; The tip of the support rod is prevented from contacting the coil spring supply chute, and a holding means is provided for temporarily holding the next coil spring that comes into contact with the coil spring supplied to the support rod.

Hereinafter, a detailed explanation will be given based on the illustrated embodiment. 1 is a coil spring supply chute arranged diagonally, with the upper coil spring supply port 1
The coil spring 2 is continuously supplied in a connected state from a. Reference numeral 3 denotes a coil spring take-out chuck disposed at the cut-out position, which can swing to the right to the working position. Reference numeral 4 denotes a rotating shaft capable of reciprocating at a certain angle, to which a swinging arm 5 is fixed, and a coil spring support rod 6 is provided protruding from the upper end of the rotating shaft in a perpendicular direction. The swing arm 5 reciprocates between the lower end position of the coil spring supply chute 1 and the cut-out position, and can be stopped at each position by stoppers 7 and 8. 9 is air cylinder 1
The coil spring presser activated by 0 presses the coil spring next to the coil spring that fell from the support rod 6. Support rod 6
is at such a height that when the coil spring 2 falls, its upper end protrudes from the upper end of the support rod 6.

Next, the effect will be explained. The rotating shaft 4 rotates to the left, and the swinging arm 5 engages and stops with the upper stopper 7, as shown by the solid line in FIG. At this time, support rod 6
is located coaxially with and opposite to the lower end of the coil spring supply chute 1. The coil springs 2 are continuously supplied in a connected state from the coil spring supply chute 1, and the lowest coil spring 2 falls onto the support rod 6, with its upper end protruding from the upper end of the support rod 6. The next coil spring 2 is pressed by a coil spring presser 9 operated by an air cylinder 10.

Next, when the rotating shaft 4 rotates to the right, the support rod 6 moves in the axial direction of the coil spring supply chute 1, and the swing arm 5 engages with the lower stopper 8 and stops at the cutting position. At this time, support rod 6
are separated in the axial longitudinal direction of the coil spring supply chute 1, so that the upper end of the moving coil spring 2 and the lower end of the next fixed coil spring 2 do not come into contact with each other, and the support rod 6 is connected to the coil spring supply chute 1. It does not come into contact with the bottom edge of the

Next, the coil spring take-out chuck 3 takes out the coil spring 2 of the support rod 6, slides to the working position, and returns to the original position after the work is completed. Repeat this action.

(Effects) The present invention has a swinging arm that swings between the lower end position of the coil spring supply chute that continuously drops the coil springs in one line and the position of the coil spring take-out chuck located at a predetermined position.
A support rod that is inserted into the lowest coil spring in the coil spring supply chute and supports the coil spring is protrudingly provided at the tip of the swing arm, and the support rod is shorter than the length of the coil spring. When the support rod stops at the lower end of the coil spring supply chute, it is located coaxially opposite the lower end of the coil spring supply chute, and when it rotates, it moves in the axial direction of the coil spring supply chute, and the tip of the support rod comes into contact with the coil spring supply chute. A holding means is provided to temporarily hold the next coil spring that comes into contact with the coil spring supplied to the support rod, so even if an external force is applied during rotational transportation of the swing arm, the workpiece will not be It is possible to reliably prevent it from falling, and it can be dropped onto the lowest coil spring support rod while in continuous contact, so the cutting time can be shortened.

Further, the number of cylinders disposed in the coil spring supply chute can be reduced by one compared to the conventional device, and the overall structure can be simplified and manufactured at low cost.
