JPS58196942A - Inserting device of disk-like ring - Google Patents

Abstract

PURPOSE:To insert disk-like rings separately one by one into a preset pin automatically and to confirm the presence of a disk-like ring by providing a pilot pin, an air intake hole, and discharge hole at the tip of an inserting head so as to provide the detection function to confirm the insertion. CONSTITUTION:A fitting base 3 is provided on an X-Y table 2. The rotation of a motor 4 is tranmitted to a cam shaft 6, which is fitted with a cam 7 for moving a head up and down and a cam 9 for sliding a separating slider 8 back and forth. A frame 10 concurrently serves as the bearing of an up-and-down slide shaft 14, which is fitted with an inserting head 18 being held by a connecting plate 21. The inserting head 18 has a pilot pin 22, intake hole 23b, and discharge hole 23c, and the head 18 is lowered following the cam 7. The pin 22 regulates the inner diameter and the head 18 is stopped descending at the position where the end face of a holder 23 is brought into contact with the slider 8. During this time, the intake air to the slider 8 is cut off and the intake air is fed to operate the holder 23, thus transferring works.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an insertion device that separates flat disc-shaped rings one by one and automatically inserts them into a predetermined bin, and that is capable of confirming the presence or absence of disc-shaped rings. It is something.

゛ Conventionally, as an insertion device for inserting a disk-shaped ring having a flat surface as shown in FIG. 1, there have been roughly two types of head mechanisms. That is, the first method is mechanical, which uses the inner diameter of the ring to
It is mechanically pushed out and held by frictional resistance, or a mechanical chuck is also used. The second method is
The disc-shaped ring is directly punched out from the hoop shape using a press method and then inserted.

However, each of these has the following drawbacks. In other words, in the case of the first method, there is a risk of damage to the inner diameter wall surface of the ring, differences in holding force occur due to variations in inner diameter tolerance, and insertion errors are likely to occur, and furthermore, it is only used for thick items. For this reason, in the case of washers made of resin materials used for mechanical parts of electrical appliances, deformation may occur in one direction or the other, immediately leading to product defects. Unfortunately, in many cases, it is necessary to separately prepare a device for confirming insertion due to functionality.
There was a problem in that it led to an increase in the total cost of equipment. Furthermore, in the second method, the mold for punching the hoop needs to be structurally strong and hold the mounting position accurately, so it lacks adaptability to changes in the insertion point, etc., and also shortens the life of the mold and makes maintenance difficult. However, it has drawbacks such as ease of processing of chips and concentricity of the inner diameter and outer diameter.

The present invention eliminates the above-mentioned drawbacks of the conventional device.It can be made into a small and lightweight unit, and an x-y table can be used in conjunction with the workpiece to reliably deliver one piece to any point without damaging the workpiece. An object of the present invention is to provide a disk-shaped ring insertion device that can insert rings one at a time and detect insertion at the same time.

An embodiment of the present invention will be described below with reference to FIG. 2 and the subsequent drawings.

Reference numeral 1 denotes a main body frame, a two-piece X-Y table, and a mounting base 3 is provided on the table. Insertion head unit 3a
Attach and detach using the mounting base 3. The rotation of the heptad 4 is transmitted to a camshaft 6 via a chain 6, and a cam 7 for vertically moving the head and a cam 9 for sliding the separation slider 8 back and forth are mounted on the camshaft 6. A part of the stopper 10a is attached to the frame 1o that supports the camshaft 6. A height switching pulse motor 11 is attached and selects a predetermined stopper bolt 13 position via a gear 12. The frame 1o on the east also serves as a bearing for the vertical slide shaft 14. The slide shaft 14 is connected to the roller 1 at the tip of the lever 15 which is interlocked with the shape of the vertical cam 7.
6 and its guide 17 so that it can be lowered by -1. The insertion head 18 shown in FIG. 7 is attached to the vertical slide shaft 14 while being held by the connecting plate 21. As shown in FIG.

The insertion head 18 has a holder 23. which guides the pilot bin 22. A contact portion 24 that serves as a stopper and a spring receiver for the pilot bin 22. and a compression spring 23 that presses the pilot bottle 22. Furthermore, there is an L holder 24 that serves as an intake and exhaust path that also serves to hold down the compression spring 23, and the holder 23a is provided with an intake hole 23b and an air extraction hole 23c.

Further, the separation slider 8 is slid by a connecting rod 19, with a lever 18a following the outer circumference of the cam 9 for longitudinal sliding. The separation slider 8 is regulated by a guide holder 25 and a holding part 26, and a separation adsorption block 27 is provided on the separation slider 8 so as to be set with a bolt. The separation adsorption block 27 is provided with a
An intake hole 27a is provided. A workpiece stock magazine 28 is attached to the holding part 26, and 29 is a photoelectric switch for stocking a certain amount of workpieces.

Next, these related effects will be explained using the timing table shown in FIG. The timing table shows one cycle of the insertion device.

First, at the start position, the X-Y table 2 is stopped at a preset first point of the work base to be inserted. The height control whistle unit is also set in advance.
It stops F'- at the position that matches the point. A flat washer as an insertion work is prepared in the stock magazine 28 by a separate feeding device 30. After the work base has arrived and the workpiece has been properly positioned, the unit receives a start signal. First, the motor 4 rotates, and the head up/down cam 79 and the front/rear slide cam 9 rotate.

Following the outer periphery of the front-back sliding cam 9, the separation slider 8 separates one inserted washer from the magazine section 28 while adsorbing it, and transports it in the direction of the arrow X. next,
The insertion head 18 descends following the head up/down cam 7. First, the pilot bottle 22 adjusts its inner diameter, and then stops lowering for a certain period of time at a position where the holder 23 of the insertion head contacts the separation slider 8. In the meantime, the air intake of the separation slider 8 is turned off, and the air intake in the holder 23 of the insertion head is operated to ensure the transfer of the workpiece. Next, the separation slider 8 moves back and the insertion head 18 descends until it hits a predetermined stopper bolt 13. At the lowering limit, the pilot bin 22 of the insertion head has a spring 23 inserted so that it is knocked out by the pin of the work base, so the flat washer may come off during its descent.

There are no missing pages. In order to further increase reliability, at the lower limit, immediately before switching from suction to blow, it is detected whether an IV-washer has been inserted based on the suction pressure. After a certain timing, the insertion head is raised to . A start signal for moving the X-Y table 2 is received at the timing of 1 nike 1, and the table moves to a preset second point. At the timing of the start of movement, the pulse motor of the height regulation unit is set to 11 and the stopper bolt is 1.
Select 3.

Thereafter, the same insertion operation is repeated for the number of insertion points, and when a predetermined number of points are completed, the workpiece regulation is removed. One cycle is performed in this way.

As is clear from the above description, the disk-shaped ring insertion device of the present invention can be used at multiple points with different insertion heights at high speed and with a detection function.
