JPH0256383A - Spool for taking-up in aligned state - Google Patents

Abstract

PURPOSE:To obtain a take-up spool allowing itself to take-up a wire in an aligned state readily by providing a protrusion of the almost same height as a wire diameter for guiding the wire at the rear of a lock hole. CONSTITUTION:Going around the core of a spool provided with a protrusion 5 on a side wall 2A along a wire pilot groove 3A, a wire looked with one end thereof inserted into a lock hole 4 and bent is pushed to the opposite side of the side wall 2A by the diameter of the wire by the protrusion 5 as wire winding proceeds. As a result, the wire is guided to the groove 3B next to the groove 3A without going on the previous turn and sliding down into a separated groove therefrom. Thus, wire take-up can be proceeded to the second turn which is most important in the important first step coil without trouble, and after that, it can be readily taken-up in an aligned state.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an improvement in a take-up spool for winding a relatively large diameter wire such as a welding wire in an aligned manner.

[Prior Art] For example, a wire take-up spool for supplying welding wire to an automatic welding machine is often injection-molded from plastic such as HI polystyrene, and has disk-like shapes at each end of a cylindrical body. A shape with a side wall is used.

In order to unwind the wire smoothly, it is important that the wire is wound around the spool in an orderly manner, so the body is usually provided with a number of parallel grooves around which the wire guides the wire. The wire rows are arranged in an orderly manner, and the wire rows in the second and subsequent stages are also wound in an orderly manner.

However, even with such a take-up spool, it is still not easy to wind the wire in an orderly manner.

[Problems to be Solved by the Invention] An object of the present invention is to solve this problem and provide a take-up spool that allows wire to be easily wound in an aligned manner.

[Means for Solving the Problems] The aligned take-up spool of the present invention has disk-shaped side walls (2A, 2B) at both ends of a cylindrical body (1), as shown in FIGS. 1 and 2. ＞, and the barrel has a number of parallel wire guiding grooves (3A) around it.

3B,...) and has a wire end latching hole (4) at one end, as shown in FIGS. 3 and 4, the latching hole (4)
It is characterized in that a protrusion (5) with a height approximately equal to the diameter of the wire (7) is provided on the inner surface of the side wall (1A) of the sliding surface and behind the latching hole to serve as a guide for the wire.

In the illustrated example, the shape of the protrusion is a triangle whose height increases along the direction in which the wire is wound, which is optimal from the viewpoint of the mechanism of action described later, but a trapezoidal or curved shape may also be used. good. It will be easily understood that the width of the protrusion (the dimension in the radial direction of the spool) is sufficient if it is equal to the diameter of the wire.

[Function] The present inventor conducted research in search of a method for winding wire onto a winding spool in an orderly manner, and found the following fact. In other words, the first stage coil on the spool is important for aligned winding, and if this coil is wound in an orderly manner, the coils in the second and subsequent stages can also be wound in an orderly manner in many cases. Even in a stage coil, the most important point is when the first winding is completed and the next winding begins, and whether or not the wire can be wound in an orderly manner as a whole is determined by the success or failure of this winding.

Since you can easily agree with the former, I would like to add a supplementary explanation for the former.The wire, which is latched by inserting the wire end and bending it, is connected to the wire guide groove (3A) in Fig. 1. According to the above, when going around the body of the spool, it is only necessary to move to the adjacent wire guide groove (3B),
Often, people try to go around the wire (7A) in Figure 4 roughly, or they slip off the wire and end up in the third wire guide groove (3C) next to it, causing a gap. wire guide groove (3B)
A phenomenon was observed in which the winding proceeded with the space left open.

To prevent this, a worker must be present at the beginning of the winding process to help the wire move correctly into the second groove.

As shown in FIG.
In a spool equipped with a wire (

In this way, if the second turn, which is the most important of the important first stage coils, can be successfully wound as shown in FIG. 4, then aligned winding can be easily done from now on.

(Effect of the Invention 1) By using the aligned take-up spool of the present invention, it is possible to wind up a wire or the like in an orderly manner by leaving it to the machine without the need for manual intervention.

Therefore, the aligned take-up spool is ideal for winding welding wire, where smooth wire feeding to an automatic welding machine is paramount.
