Description

Detailed Description of the Invention The present invention provides a flat spring electric wire reel for unwinding only the required length of electric wire from a reel and for preventing sagging due to unwinding of unnecessarily long electric wire. This invention relates to a stopper device.

Electrical wiring used in aircraft, space (tables, etc.)

With the development of electronics, the area has been rapidly occupied in recent years. Therefore, processing work for the 7L line (measurement of the 'fli line Jk.

Cutting, identifying markings, and terminal processing (RF) are also on the rise. The labor involved in this process is increasing and automation is becoming necessary. When automation is used, the speed at which wires can be processed is of course important. If it is too slow, there is no point in automating it.

In order to increase this speed, it is possible to shorten the entire series of processing operations, but a factor that greatly affects speed is the time it takes to unwind the wire from the reel for wire processing. Traditionally, the simplest method for rewinding is shown in Figures 1 and 2.
It is applied in the manner shown in the figure.

In FIG. 1, the electric wire 1 is simply pulled out from the reel 2.

In FIG. 2, a yo-yo (idler) 5 is installed between the reel 3 and the idler 4 in order to keep the tension of the electric wire 6 as constant as possible.

Next, the drawbacks of the unwinding device shown in FIGS. 1 and 2 will be explained.

In the device shown in Fig. 1, when the wire l is suddenly pulled in order to improve the wire unwinding speed, the inertia of the reel 2 causes
1! Excessive tension is often applied to line 1. This can damage the wires and may cause them to break.

In the apparatus of Figure 2, to avoid excessive tension.

This is the addition of 5 yo-yos (idlers).

In this case, excessive tension in the electric wire 6 would be avoided, but it would become a problem when stopped. In other words, even after the wire rewinding is stopped, the reel 3
The reel 3 rotates due to the rotational inertia of. For this reason, the electric wire becomes slack as shown by the one-dot line 7, and the IT wire becomes tangled or falls off.

The present invention has been made to improve the above-mentioned drawbacks and to prevent problems and accidents when unwinding electric wires.

A brake disk fixed to the rotating shaft of the electric wire reel and rotating integrally with the electric wire reel, a brake body attached to the brake shaft and fixed integrally with the brake shaft, and a brake disc rotatably attached to the brake shaft. Maintain the idler and brake shaft.

When unwinding the electric wire, the electric wire tension via the idler releases the contact between the brake body and the brake disc, allowing the electric wire reel to rotate, and when the electric wire reel is finished and the electric wire tension disappears, the brake body and a plate spring mechanism for restoring contact between a brake disc and a plate spring type glans line reel stopper device.

An embodiment of the flat spring WE wire reel stopper device of the present invention will be described.

FIG. 3 is a perspective view showing the structure of the device of the present invention.

Reference numeral 11 indicates an electric wire, and reference numeral 12 indicates an electric wire reel, which is rotatably attached to a reel support member 1o on a support base 2° via a shaft 19. Reference numeral 13 is a brake disc 4p fixed to the wire reel 12 and formed into a single piece, with a plate spring 1sa.

15b via the brake shaft 18.

A primary idler 6 is connected to the reel support section 4 via the shaft 21.
It is attached to ito. A secondary idler 17 is attached to the brake shaft 18.

Next, the operation of the device having the above structure will be explained.

This device is one of the generally developed "automatic wire processing devices" that can be used to unwind wires from a wire reel stocker.
This is a device to prevent accidents caused by walnuts on electric wires.

Current wire reel stockers are equipped with idlers.

'4! If the line tension is strong, it is impossible to control the rotation of the lane reel.

In the device with the above structure, the leaf springs 15&, 151)...
-Ya□4 Wow. Yoyoyo, line. 22. 'Mi can be prevented. The electric wire 11 is passed from the electric wire reel 12 to the primary idler 16
, and is pulled via the secondary idler 17. By pulling the electric wire 11.

The leaf springs 15a and 15b are deformed to form a leaf spring 15a.

Brake 14 is coaxially fixed with zsb.

The contact of the brake disc 13 fixed to the mold sand luer 2 is released, the wire reel 12 rotates, and the required length of wire is rewound.

As a result of the required amount of wire being unwound, the tension in the ``c wire''
When set to 0', the force of the leaf springs 15a and 15b causes the return brake disk 13 and the brake 14 to come into contact, and this resistance stops the rotation of the wire reel 12 and at the same time, the unwinding of the wire is also stopped. Walnuts can be prevented.

The brake 14, the brake shaft 18, and the leaf spring 15 are either rigidly fixed or adjusted so that they can rotate with appropriate frictional force, so if the brake 14 and the brake disk 13 come into contact, the reel 12 rotations can be controlled.

FIG. 4 is a different embodiment from that shown in FIG. 3, and the structures indicated by numbers 12 to 15, 17, 18, and 19 are the same as the device in FIG. 3. The difference is that the wire reel 12 is a reel support member 22.
However, the primary idler of the device shown in FIG. 3 is removed, and a floating rotating top (yo-yo) 9 is provided in its place. The idea was to do pull-ups. This is a combination of the conventional device shown in FIG. 2 and the effects of the leaf spring and brake of the present invention, and it is possible to keep the tension of the Ii wire 11 almost constant and prevent the wire from loosening.

According to the plate spring type electric wire reel stone bar device according to the present invention described above, by providing a brake that utilizes a plate spring, the braking action is released when unwinding the electric wire from the electric wire reel.

After unwinding the wire to the required length, the brake can be applied to control the rotation of the wire reel to prevent the wire from curling. Furthermore, this effect eliminates tangles and falling off of wires when unwinding the wires, shortens wire processing time, and enables highly efficient work.
