Description

[Detailed description of the invention] This invention fits two parts A and B according to their dimensions,
This relates to the device to be combined.

Let us now refer to the two mating parts as A part and B part.

The applicant has previously developed a device that measures the dimensions of part A, stores them in memory, selects a matching part from the measured values of part B, and combines A and B. The invention was filed under Application No. 51-143137 (Japanese Unexamined Patent Publication No. 5367179).

The present invention is an improvement on this device and relates to a device that is simple and easy to manage.

In the present invention, the measurement, storage, and assembly of parts A and B are performed on one upright board, which has the feature that operation, management, and repair are very simple.

In FIG. 1, the first conveyor disk 1 of part A is attached to the upright plate 21 on the lower right side.

The first conveying plate 1 is provided with a plurality of notches 2 at equal intervals on its outer periphery, so that the part A is inserted into the notches 2. Let it rotate.

When one notch 2 comes to position C, remove part A 1
Drop into it.

Next, when this rotates to the D position, the dimensions of the fitting portion of the parts are measured inside the first conveying disk 1.

Note that the dimensions are measured by a conventionally known method, so the explanation thereof will be omitted.

When it rotates one more time and reaches position E, part A is taken out by the first take-out device 3 and stored in position F of the storage magazine 5 for parts A attached to the upright plate 21.

In the storage magazine 5, a large number of storage locations 6 are provided at equal intervals on the same circumference, and the locations are numbered and stored together with the dimensions of the stored parts A.

In this way, the storage location 6 of the storage magazine 5 is completely filled with A parts.

At the bottom left side of the figure is a second transport disk 7 for transporting part B.
is attached to the upright plate 21.

The second conveyance disk 7 is provided with a plurality of notches 8 at equal intervals for receiving parts B, and, contrary to the first conveyance disk 1, the notches are intermittently rotated clockwise one by one. .

Then, at the G position, place the B part 1 for each notch.
After receiving the pieces, the dimensions are measured at the H position, and the assembly position I is reached.

Here, for the dimensions of part B that has come to position ■,
A part is selected from the storage magazine 5, and the storage magazine 5 is rotated so that the position where the part is stored comes to the F position.

A second take-out device 9 moves together with the first take-out device 3.
(The tip part is omitted in the figure), the A part at the F position is taken out and combined with the B part at the ■ position.

At the same time, part A at position E is placed in the empty storage area at position F, and the memory of the dimensions is updated.

Then, the second conveyance disk 7 rotates, and at the J position, A,
B The combined parts are ejected together and sent out as a set.

Note that both A and B parts that are outside the allowable dimensions are ejected at appropriate positions.

Note that the B parts that do not match the A parts in the storage magazine 5 may be discharged separately, or they may be left on the second transport disk 7 and the A parts that can be combined are stored in the storage magazine 5. It may be rotated a predetermined number of times.

FIG. 2 shows the mechanism of the storage magazine 5 described above.

The storage magazine 5 is mounted on the shaft of a pulse motor 10 mounted on an upright plate 21.

Then, according to the command, it is rotated by a fixed angle so that the storage position of the specified address is at the specific position F.

For this purpose, an address display plate 11 is attached to the storage magazine 5, and a reading device 12 pinches this plate to confirm the stop position.

Further, in the center of the lower part of FIG. 2, a shaft 13 on which the first and second take-out devices are attached is attached to the upright plate 21 at right angles, that is, horizontally, so that it can move forward and backward as well as rotate.

Here, forward movement and backward movement are performed by a mechanism of a cam 14 and a rod 15 on the back side of the upright plate 21, and rotation is performed by a gear train 16.

A bar 17 is attached to the front end of the shaft 13, and a first
, a second extraction device 3,9 is mounted parallel to the upright plate 21.

Then, as the shaft 13 moves forward, the first and second extraction devices 3 and 9
The chucks provided at the respective tips simultaneously hold part A and move it away from the E and F positions, and then, by rotational movement, the tip of the first take-out device 3 moves from the E position to the F position, and the second take-out device 9 moves from the E position to the F position. The tip turns from the F position to the ■ position, moves the A part to the storage magazine 50F position and the A part to the ■ position by a backward movement, and releases each chuck to store the A part, A, and B parts. Assemble parts.

The first and second ejecting devices 3 and 9 have a holding and releasing mechanism at the tip for holding the part A at the E position and the F position and moving it to the F position and the ■ position. A mechanism is used, which has a pair of claws that enter the hole to open it or grasp it from the outside, and opens and closes it according to commands, that is, what is generally called a chucking mechanism.

FIG. 3 shows an example of the mechanism, in which the first extraction device 3
, is attached to its tip at right angles to the plane of the paper in FIG.

As described above, the first and second take-out devices 3 and 9 are fixed to a bar 17 attached to a shaft 13 that rotates at a fixed angle.

In FIG. 3, the claws 22 and 23 at the tips are arranged close to each other, and their outer diameter is smaller than the inner diameter of the hole in component A.

Then, when the claws 22 and 23 enter the holes A as they move forward (in a downward direction perpendicular to the paper plane of FIG. 1) at position E, the cylinder 20 provided above the claws is activated.

Here, the pawls are each biased toward each other by a plate spring 24, 25.

Then, by the operation of the cylinder 20, the piston rod 2
6 moves, pushes the middle part of the two leaf springs 24, 25 with its tip, opens the claws 22, 23 outward, and holds A.

Then, the shaft 13 moves from the plane of the paper of FIG.

By means of an angular pivoting of the shaft 13, the holding part is then rotated to the left and is now advanced towards the storage magazine 5, placing A in its storage location 6 and discharging the pressurized air of the cylinder 20.

At this time, the rod 26 is moved backward by the spring built into the cylinder, and the claws 22 and 23 contract their outer diameters by the leaf springs 24 and 25, and are freed from A.

Then, it retreats from the storage magazine and turns further to return to position E.

The second take-out device has exactly the same mechanism as above, and opens by inserting a claw into A at position F, and inserts part A into part B at position ■ to reduce the size and assemble it.

By setting the turning angles of E-F and F-I to be the same, the two take-out devices 3 and 9 can be operated simultaneously by the turning movement and forward/backward movement of one shaft 13.

As explained above, in the present invention, the storage magazine 5
, first and second transport disks 1 and 7, first and second take-out devices 3,
9, the measuring section, etc. are all attached to the front of the upright plate 21, and the storage of the part A into the storage magazine and the insertion into the assembly position proceed at the same time by a fixed angle rotation movement of one axis, so the mechanism is simple. It can be operated efficiently.

All of the drive mechanisms are located on the back side of the upright plate.

Therefore, managing and repairing the device is simple and easy, and its operation can be easily checked.
