Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for mounting a washer, particularly a flat washer, to a predetermined location, and a device for mounting the same.

Conventionally, washers attached to the rotating shaft of tape recorders were attached one by one by hand, but the work efficiency was very poor, especially when the washer had an inner hole with a smaller diameter than the outer diameter of the shaft. This was especially true since it had to be pushed in from above.

However, since there are so many different models, it has been difficult to use large-scale mounting devices from a financial standpoint.

The present invention improves these problems, and provides a washer mounting method and device with very good workability by operating the washer by applying the suction force of air. .

DESCRIPTION OF THE PREFERRED EMBODIMENTS A washer mounting method and its mounting device according to the present invention will be described below with reference to the drawings.

1 to 3, the washer mounting device of the present invention consists of a round rod-shaped gripping body 1, and a suction part 3 of a smaller diameter is removably installed at the lower end 2 of the gripper by means of a screw type or the like. .

This suction part 3 is made up of an outer cylinder 4 and a core 5 fitted into the outer cylinder 4.

The outer periphery of the lower end of the core 5 is thinned and has a stepped portion 6, and this portion and the inner periphery of the outer cylinder 4 form a cylindrical groove 7.

Also, on the outer periphery of the thick portion of the core 5, a plurality of vertical grooves extend to both the upper and lower ends.

Reference numeral 9 denotes a recessed hole for accommodating the washer mounting portion, and is formed to have the same diameter as the inner hole of the washer.

The ventilation holes 8 made up of the plurality of longitudinal grooves are aggregated at the top and become one, and the air holes 1 open at the lower end of the gripping main body 1.
It is connected to 0.

This air hole 10 is also opened on the side surface of the gripping body 1, and a rubber elastic membrane 12 is fixed around the gripping body 1 at the top and bottom with metal crimp bands 13, etc., surrounding the opening 11. It has been installed.

The elastic membrane 12 has a swollen central portion and normally contains an air layer therein.

The washer mounting operation using the mounting device according to the present invention is performed as follows.

That is, the tip of the suction part 3 having a cylindrical groove 7 formed in advance according to the inner and outer diameters of the washer 15 is pressed against the washer 15 in the washer container 14 in accordance with the size of the washer 15. At this time, the washer 15 is attracted to the lower surface of the suction part 3 and lifted when the elastic membrane 12 of the mounting device is once grasped to vent the air inside and then the grip is loosened.

In that state, insert the washer 1 onto the specified washer mounting part.
After fitting the washer 15, when the elastic membrane 12 is grasped again, an air flow is generated in the discharge direction, and the washer 15 is easily removed from the suction section 3, completing the attachment to the washer mounting section.

The washer mounted by the method of the present invention can be operated while always keeping the washer horizontal, which reduces mounting errors, and since no hot wire is required, the work efficiency has dramatically increased.

The mounting device of the present invention may be one in which an elastic membrane is formed on the top of the gripping body, and therefore the end of the air hole is also formed on the top of the gripping body, and if the washer is heavy, etc. Alternatively, the air hole may be connected to an air hose, a switch may be provided on the gripping body, and the switch may be used to switch between air intake and air supply.

Furthermore, by preparing several types of suction parts 3 in advance, changes in models can be quickly dealt with.

In addition, not only the suction part 3 but also the outer cylinder 4 and the core 5 of the suction part 3
By making each of the parts removable, it is possible to efficiently replace parts due to wear and the like.

Next, examples of washer containers are shown in FIGS. 4 and 5.

The washer container 14 shown in FIG. 4 has a large-diameter stabilizer plate 16 at the bottom, and consists of a cylindrical body 17 that stands upright above the stabilizer plate 16.

A finger hole 19 penetrating vertically is formed in the portion of the stabilizing plate 16 located inside the cylindrical body 17, and a vertical groove-shaped opening 18 extending over almost the entire length of the cylindrical body 17 is formed on the side surface of the cylindrical body 17. The inside of the shaped main body 17 is formed to be open.

On the other hand, a large number of washers 15 housed in this washer container 14 are stacked in advance and connected by adhesive tape 20 affixed to the side surfaces. In front is the adhesive tape 2
0 is peeled off by inserting a finger into the longitudinal groove-shaped opening 18 of the cylindrical body 17 and pulling out one end thereof.

By undergoing such operations, the washer 15 can be put to use in an organized state immediately after the manufacturing process.

Therefore, the working environment has been improved and work efficiency has also been significantly improved.

FIG. 5 shows another example of a washer container.

This washer container 21 has a cylindrical body 23 whose inner circumferential surface 22 has a rectangular cylindrical shape, and the washer 15 is attached to a rectangular case 2 in this case.
4 is housed in the cylindrical main body 23 with the hole still in place.

25 is a finger hole for ejecting the case 24.

In both cases of Fig. 4 and Fig. 5, the distance from the upper end of the cylindrical body to the top of the washer 15 accommodated is adjusted to have a constant depth, and the mounting device does not cover this washer 15 during actual use. It can be placed upright inside the container.

As described above, according to the method and apparatus of the present invention, since the washer is attached and detached by letting air in and out, there is no risk of the washer becoming bent, and workability is greatly improved.

It is also now easier to attach it in places where it is difficult to attach it with your fingers.
