Abstract

PURPOSE:To prevent a reel from rotating excessively and prevent a wire or the like from loosening in winding, by a method wherein rollers bearing a reel thereon are pressed by spring forces at the time of drawing out a wire from the reel, in a device for drawing out a wire from a reel. CONSTITUTION:The wire 11 is drawn out in Y-direction, the reel 10 is moved to the position indicated by dot-dash lines against the frictional force wirking between the reel 10 and a rod form member 3, and is mounted on the first and second rollers 2, 6. When further drawing out the wire 11, the reel 10 is rotated together with the rollers 2, 6 to enable the wire 11 to be drawn out. In this case, the first roller 2 is pressed by a spring force, and the second roller 6 is pressed by springs 7, thereby preventing the reel 10 from rotating excessively and the wire 11 from being drawn out excessively from the reel 10. When the drawing- out of the wire 11 is completed, the reel 10 is remounted on the rod form member 3 and the second roller 6 to return to the initial condition.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a wire rod supply device that can draw out a wire rod only when the wire rod is pulled out from a reel with a certain force or more.

This is a wire feeding device that feeds more than a conventional reel.

A shaft was attached to the reel and the wire was pulled out and supplied, but the tensile force of the wire generated inertia on the reel, causing wires that were longer than the desired length to be pulled out, causing the wire to dangle and get dirty. Otherwise, the wire may become entangled with other equipment, causing a failure and causing a good wire to be cut, which may have a sudden impact on the next process.

So, clutch.

Although a brake or the like is used to forcibly stop the rotation of the reel, there is a drawback that the device itself becomes complicated and extremely expensive.

In addition, the conventional configuration in which the shaft is passed through the reel has drawbacks such as the time required to attach and detach the reel and the need for a tool for attaching and detaching the reel.

The present invention was developed in view of the above-mentioned drawbacks, and the reel can be easily attached and detached, the wire can be pulled out only when the wire is pulled out with a certain force or more, and the inertial force can be braked. The purpose of the present invention is to provide a wire feeding device.

An embodiment of the present invention shown in the drawings will be described below.

In Figures 1, 2 and 3, l is a frame;
2 is a roller that is rotatably taught to this frame 1 and has a franchim; 3 is made of a material with a large coefficient of friction;
A rod-like member fixed to the frame 1 at an appropriate distance from the roller 2; 4 a spring inserted into the support shaft 5 and pressing the roller 2 toward the center; The small diameter roller 7 is a spring inserted into the support shaft 8 and pressing the roller 6 toward the center.

Next, the operation of the present invention will be explained.

First, the reel 10 is placed on the rod-shaped member 3 and the roller 6. Therefore, unless a force is applied to the wire rod 11 wound around the reel 10 in the Y direction in FIG. 1, the braking force is applied and the wire rod 11 does not rotate because of its large friction coefficient with the rod member 3.

However, when the wire 11 is pulled out in the Y direction, this pulling force causes the 13-ru 10 to reach the 1st rI! JK Move to the position indicated by the one-dot chain line. That is, when the reel 10 is piled up on the rollers 2 and 6 and the wire 11 is pulled out, the reel 10 rotates together with the rollers 2 and 6, and the wire 11 can be pulled out. Here, the roller 2 is pressed by the butterfly spring 4, and the roller 6 is pressed by the spring 7, so the reel 10 rotates more than necessary, and the wire rod 11 is rotated more than necessary. Prevent rotation.

When the drawing of the wire rod 11 is finished, the reel 10 rides on the rod member 3 and the roller 6 again. i.e. original state) II
Move tK.

This means that when the roller 6 moves over the rollers 2 and 6, an appropriate angle is set from the center of the reel 10 (δ in Fig. 1).
) Since it is installed in an inclined position, reel 1
This is because the weight of zero always acts downward, and therefore when the pulling force in the Y direction disappears, it comes into contact with the rod-shaped member 3.

In this state, as described above, since the friction with the reel 1O is large, the reel does not rotate, and braking is applied, resulting in a good state.

In the above description, the rod-shaped member 3 is used, but other shapes may be appropriately selected as long as they can increase the friction.

Since the present invention is configured as described above, it brakes the inertial force generated when pulling out the wire rod from the reel, and prevents the #a material etc. from sagging, thereby preventing contaminated equipment and other equipment. No more getting tangled in water. As a result, failures caused by sagging of the wire rod and effects on the next process are eliminated, and the apparatus can be made inexpensive because there is no need for a position. In addition, the conventional method of passing the shaft through the reel takes a long time to attach and detach, and also requires tools, which is dangerous. Reel i removal time can be significantly reduced.

This has the advantage of not requiring the use of tools.
