Abstract

PURPOSE:To automate processes by vertically inputting a magnetic ring material having a projection on the periphery of one side surface, in a shoot, judging whether it is front or back side based on the detection whether there is the projection or not, during its moving in the shoot, and by receiving the material in a vertical form from the shoot through an angle changing plate, so as to change directions based on the judging effect. CONSTITUTION:A magnetic ring material 61 in a hopper 1 is absorbed by a magnet 6 of a disc 4 rotated by a motor 7, and is supplied to a shoot 11, in a vertical position. A projected horn 23 is protruded to the end of the shoot 11, while the magnetic ring 61 is held between a pair of T-shaped projections 17, and the magnetic ring 61 in next position is held by a cylinder 20. Whether there is the projection of the head ring 61 or not is judged by a detector which is not indicated in the drawing. Cylinders 48, 48a are preferentially driven based on the detection signal, and the engagement of guide grooves 41, 41a of a circular guide rod 26 and rods 49, 49a, is selected. Front side and back side are fitted by rotating an angle changing plate 27 in the direction where the front side and the back side are fitted together. In this structure, automation can be achieved.

[Detailed Description of the Invention] (5 Industrial Application Fields) The present invention provides front and back sides of magnetic ring material! II''AIJ *Regarding the placement, place a magnetic ring material that is distinguished into the front and back sides by the presence or absence of protrusions vertically with a groove of about the thickness of the ring + 1) h
- Feed the magnetic ring material into the chute without aligning the front and back sides, detect the front and back sides by the end of the chute, and receive a piece of magnetic ring material with the angle conversion plate that becomes vertical at the forward position connected to the end of the chute. , the conversion plate is made horizontal in a retracted position where the clockwise rotation is retracted counterclockwise according to the front 2 detection signal, so that the front or back surfaces are aligned.

(Conventional technology and problems) For example, magnetic ring material formed at regular intervals of 1711 times has protrusions on one side circumference of a retainer that is pronoection welded to a fuel tank. If you don't have it, you can create two sides.

Traditionally, the standard of technology was to rely on the manual work of two people stacking a large number of pieces while visually checking the front and back sides.
This has the problem of poor work efficiency.

However, no device has been provided that allows ring materials to flow into a chute in a line without aligning the y2 back sides and automatically aligning the front or back sides.

(2ffi/object of the invention to be solved by the invention) The present invention distinguishes the front and back sides of a magnetic ring material in which several protrusions are formed on one side at approximately constant angular intervals, and automatically aligns the front or back sides.

At the same time as the chute 11 enters the part where the rod 20a is missing, the chute 11 instantaneously turns the rod 20a back, moves the magnetic ring material 61 that is pressed against the wall plate 12 onto the protruding beak 28, or presses it against the wall plate 12. When it hits 29, the cylinder 20 operates at the same time,
At that time, the next magnetic ring material 61 is placed on the rod 20a.
The operation of pressing against the wall plate 12 of the chute 11 to prevent the flow from flowing down is repeated.

(Operations and Effects) As has been made clear from the explanation of the above-mentioned embodiment, the present invention provides the front and back sides of the magnetic ring village 61 that is randomly and vertically supplied to the chute 11 without distinguishing between the front and back, and the flow of the chute. On the way, the angle conversion plate 27 is detected when the detection is completed, and is displaced vertically in the forward position, and in the horizontal force direction in the backward position.At the forward position Ii, the angle conversion plate 27 receives the magnetic ring material 61 from the end 15 of the chute 11, and retreats. 11.41 is a clockwise or counterclockwise guide groove provided in the axial direction of the circular tipper 2G that advances and retreats together with the angle conversion plate 27 in response to the above-mentioned detection signal.
In a, the engagement pin receives the front/back detection signal, t 9.49
Selectively fit one force of the engaging pin 49.49 of the signal receiving member such as the cylinder 48.43a into which any of the above is fitted, and attach the front or back surface of the received magnetic ring material 61 to the circular rotary rod 2.
Since it can be aligned by turning G by 90 degrees clockwise or counterclockwise, it has the effect of freeing up the work that used to be done manually.
