[Conventional technology]

As shown in FIG. 5, the E-shaped clip 1 is a small part made of a thin plate of spring material, which has a partially open annular shape, and is often used to prevent small particles from being removed. When assembling the E-shaped clip 1 to a shaft or the like, it is inconvenient to handle with fingers, so it is held in a holder 2, which is a special holding tool. The Hollug 2 has a circlip holding part 4 made of a metal plate fixed to the tip of a grip part 3 made of synthetic resin or the like. The circlip holding part 4 is divided into two halves at the distal end, right and left, and a U-shaped set part 5 at the distal end is slightly expanded left and right to hold the E-shaped clip 1. 6th
The figure shows a state in which an E-shaped clip 1 is clamped.

Generally, a large number of E-shaped clips 1 are stacked and supplied in a state where they are easily separated and joined together. In order to take out a large number of stacked and joined E-shaped clips 1 one by one and hold them in the holder 2, a stand 7 having an alignment guide 6 as shown in FIG. 7 has conventionally been used. A large number of joined E-shaped clips 1 are placed on the reference surface 8 of the stand 7 while being guided by the alignment guide plate 6, and the lower surface of the circlip holding part 4 of the holder 2 is placed along the reference surface 8. At the same time, the set part 5 is pressed against the E-shaped clip 1, and the lowest E-shaped lip 1 is held and taken out.

However, the E-shaped clip 1 is an extremely thin small elastic plate with a thickness of about 0.4 mm, and as shown in FIG.
There was a ffi point in that holding the circlip with the circlip holding part 4 required skill, increased working time, and became a major factor hindering improvement in productivity.

[Problem that the invention seeks to solve]

The present invention has been made in order to solve the above problems, and it is possible to very easily take out one circlip from a large number of stacked and joined circlips by properly holding it in a holder. An object of the present invention is to provide a circlip extraction device.

[Means for solving the gap]

For this reason, the present invention includes a stand equipped with an alignment guide plate that guides a large number of circlips stacked on a reference surface, and a stand that is slidable on approximately the same plane as the reference surface;
A slide jig having an engaging portion on an upper surface, a driving means for reciprocating the slide jig from a predetermined position to a predetermined position, and a circlip holding portion for holding a circlip, and a circlip holding portion for holding a circlip, A circlip comprising: a holder that engages with a mating portion and is reciprocated on a reference surface of the stand integrally with a slide jig; and a guide member that guides a circlip holding portion of the holder. The extraction device is criticized.

[Effect]

According to the above configuration, the circlip is guided by the alignment plate to maintain a constant position on the reference plane.

On the other hand, the holder is engaged with the engaging portion of the slide jig and is sent over the reference surface integrally with the slide jig.

Then, the holder is guided in the left and right directions by the guide member, and is accurately sent to a predetermined position e by the drive means and pressed against the circlip, so that the circlip can be reliably and appropriately clamped, and the operator's skill can be improved. I don't have to rely on anyone.

Further, a band-shaped rubber material 16 is fixed to the upper surface of the slide jig 13 near the pin 14. The band-shaped rubber material 16 is placed slightly in front of the holder 2 which is attached to the slide jig J413.
This is a member for making the A microswitch 17 is attached below the slide jig 13 to detect that the holder 2 is mounted on the slide jig 13.

FIG. 4 is a perspective view of the holder 2, which is a special tool for holding the E-shaped clip 1 one by one.

A thin plate-shaped magnet 18 is mounted near the base of the circlip holding portion 4 of the holder 2 using J[material].

Further, an id bush 19 is embedded near the center of the grip portion 3 to form a positioning hole 20. When attaching the holder 2 to the slide jig 13, the positioning hole 20
is fitted into the protruding pin 14 of the slide jig 13 to determine its position in the front-back direction, and the magnet 18 attracts the magnet 15 of the slide jig 13 to determine the approximate left-right direction. At this time, the holder 2 is slightly tilted forward by the band-shaped rubber material 1G on the upper surface of the slide jig 13, and the front #1 portion of the circlip holding portion 4 comes into close contact with the reference surface 8.

An air cylinder 721 is fixed inside the stand 7, and its piston rod 22 passes through the stand and the stay 12 and projects forward. The slide jig 13 is attached to the piston rod 22 and is reciprocated by the stroke of the air cylinder 21. Inside the air cylinder 21, cylinder auto switches 23 and 24 that detect the forward end of the stroke and f&''Aya are built in.
Driven by idle valve 25, separately placed electric control box 2
Controlled by signals from 6. Inside the electric control box 26, an electric circuit is constructed which is activated by a signal from the microswitch 17 that detects attachment of the holder 2 and causes the air cylinder 21 to reciprocate once.

Two block members 31 and 32 are fixed on the stay 12 and guide both sides of the grip part 3 of the holder 2. Also,
Guide plates 33 and 34 that are open upward are fixed to the upper surfaces of the left and right block members 31 and 32, respectively, and guide the movement of the holder 2 in the vertical direction. Furthermore, stand 7
A vertically shaped t-id plate 35 is provided upright on the reference plane 8 . Therefore, the holder 2 is moved by the sliding jig 13.
When attaching the holder 2 to the guide plate 33., press the tip of the circlip holding portion 4 of the holder 2 against the guide plate 35.
34 and lower the positioning hole 20 of the holder 2 and the magnet 18 to the pin 14 of the slide jig 13.
It also has the advantage that it matches the position of the magnet 15 and can be easily attached. Needless to say, the lower end of the γ-id plate 35 has a gap through which the circlip holding portion 4 is inserted.

Plate-shaped guide members 36 and 37 are fixed on the reference surface 8 of the stand 7. The guide members 36 and 37 guide both gA surfaces of the circlip holding part 4 of the holder 2, go up the pin 14 and the positioning hole 2o, and closely determine the direction of the holder 2, which is positioned by one-point support, so that the tip of the holder 2 set n5 of E
Shape - precisely guide the clip 1 into position.

The operation will be explained based on the above configuration.

First, the operator presses the tip of the circlip holding part 4 of the holder 2 against the vertically shaped guide plate 35 and lowers the holder 2 by letting the guide plates 33 and 34 guide the left and right sides, and then lowers the holder 2 onto the slide jig 13. Attach to. At this time, the positioning hole 2o of the holder 2 and the pin 14 of the slide jig 13 are inserted into the positioning hole 2o of the holder 2 under the guidance of the guide plate 35 and the guide plates 33 and 34, and the position of the holder 2 is determined. Then, the holder 2 is placed on the slide jig J413 with a slight FR by the rubber material 16, and is attracted by the magnetic force of the magnet 18 and 1/15, so that the tip i part of the circlip holding part 4 of the holder 2 is attached to the stand 7.
is pressed onto the reference surface 8 of

When the holder 2 is mounted on the slide jig 13, the grip part 3 of the holder 2 presses the micro switch 17 and gives a signal to the electrical control box 26 - this signal automatically starts the sequence. The cylinder 21 is driven and the slide A-13 and the holder 2 start moving forward. The holder 2 is guided by guide members 36 and 37 on both sides of the tip of the circlip holding part 4, and moves forward with the direction precisely regulated.

The holder 2 moves forward with its position and direction regulated by the pin 14 on the slide jig 4:13, the reference surface 8 of the stand 7, and the left and right guide members 36.37, so that the U-shaped set portion 5 at the tip is aligned. The set portion 5 is inserted through the guide plate 6 and pressed against the lowest one of the stacked E-shaped clips 1, and the set portion 5 is slightly expanded left and right to sandwich the E-shaped clips 1. When the slide jig 13 reaches the forward end, the auto switch 23 operates, the solenoid valve 25 is switched, and the slide jig 13 starts moving backward. At this time, the slide jig 13
The forward end position of the holder 2 is precisely determined by the air cylinder 21, and as shown in FIG. It is possible to set a gap that is as small as a gap and hold it in the set part 5. Note that due to the gap, only the lowest one of the circlips 1 can be separated from the aligned id 4!6.

When the slide jig 13 returns to the rear end, it stops at that position.6 The operator holds the E-shaped holder 2 with the clip 1 held therein.
can be grasped and moved on to assembly work.

Further, the E-shaped clips 1 inserted through the alignment guide plate 6 fall due to their own weight, and the one at the lowest level contacts the reference surface 8 and waits to be taken out next.

As mentioned above, the series of operations for holding one E-shaped clip in the holder 2 and taking it out from a large number of stacked E-shaped clips are all performed automatically.
Since the operator is not required to be skilled and the operator's movements are extremely simple, the number of man-hours can be significantly reduced.

Furthermore, since the E-shaped clip 1 is accurately held in the holder 2 without variation, the number of steps in the assembly process can be reduced, and productivity can be greatly improved.

In the above explanation, the operation was explained as being performed manually by the operator, but by using the take-out device according to the present invention, it becomes easy to operate the holder 2 with a simple robot or manipulator, and it is possible to operate the holder 2 with a simple robot or manipulator. This makes it possible to manufacture an assembly machine.

〔Effect of the invention〕

As explained above, since the circlip dispensing device of the present invention has the above-mentioned groove configuration, it has the excellent effect of automatically allowing the circlip to be accurately and appropriately held in the holder and taken out. Therefore, a large ripple effect can be obtained in that the working time can be significantly reduced.
