Abstract

PURPOSE:To prevent collapse of the wire strip wound round takeup reel near its flanges by giving the reel a form with thcikner middle part with reducing diameter toward the flanges on both sides and by making uniform the thickness of winding throughout the length. CONSTITUTION:The drum part 5 of a takeup reel is given such a form that its diameter is largest in the middle reducing gradually toward the ends adjoining the flanges 6 on both sides. Accordingly if any material, wire or strip, is wound up, a time lag is generated when the material is turned over in winding at one of the flanges 6. Even though the material is wound in extra in the neiborhood of the flange owing to this time lag, this part of drum can house more material than the central part because its diameter is thinner than that of the central part, so that these two parts of drum 5 are not much different in thickness of winding. Thus material is wound approx. uniformly throughout the length of drum 5 to prevent the material wound near the glange 6 from collapsing over the portion of same material wound nearer the central part.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a reel for winding up a metal material such as two long wire rods.

Generally, when winding a long wire rod (hereinafter simply referred to as material) made of metal material, flanges 2 are provided on both end faces of the body l as shown in FIG. use,
It is mainly wound around the body 1 using an automatic winding machine.

By the way, when the entire material is wound up using such a reel 3, since the body part 1 is flat, a time gap occurs when the material is turned back and wound up at the 7th lunge 2.
As shown in the figure, the amount of material 40 wound up is small near the center of the body 1, and as it approaches the flange 2, the amount of material 40 wound up increases.
There was a tendency for the winding condition to become drum-shaped.

If the material 4 is wound onto the reel 3 in the state shown in FIG.
The material near the flange 2 collapses and overlaps the material 4 around the center of the body. If the material 4 is pulled out in such a state, the material 4 will be scratched, which may cause contact failure, especially if the material 4 is an electrical contact material.The present invention has been made to solve this problem. It is an object of the present invention to provide a reel which prevents the material from being wound into a drum shape even when the material is wound up using an automatic winding machine.

Hereinafter, the take-up reel according to the present invention will be described with reference to FIG. 3. Seven lunges 6 are provided on both end surfaces of the body 5, and the diameter of the body 5 is increased from the center of the body 5 to both ends in contact with the seven flange 6. The body 5 is formed into a spindle shape by gradually decreasing the diameter.

When the winding reel 7 having such a structure is used to wind up many materials on an automatic winding machine, a time lag occurs when the material is folded back and wound around the flange 6. Even if extra material is wound up in the vicinity, the diameter of that part is smaller than the diameter of the central part, so more material can be wound up than the central part, and therefore a predetermined amount of material 4 can be wound up as shown in FIG. reel 7
Even when wound up, the thickness of the material 40 can be wound without much difference between the central part of the body 5 and the vicinity of the 7 flange 6.

In this way, the material can be wound up at approximately the same speed over the entire length of the body 5, so that unlike the conventional take-up reel 3, the material near the 7 lunges 2 collapses due to vibration etc., and the material around the center part collapses. As a result, when the material 4'f is pulled out from the reel 7 for use, it can be smoothly pulled out and the material 4 will not be scratched.

Further, if a predetermined amount of material is not wound on the winding reel 7, the wound state will be spindle-shaped, but since the material 4 is wound evenly around the center, it will not collapse.

The difference in the diameter of the body 5 between the central part and the vicinity of the 7-lunge 6 depends on the dimensions of the material to be wound.

It is determined appropriately depending on the shape and winding t.

Next, in order to clarify the effects of the take-up reel of the present invention, specific examples and conventional examples thereof will be described. [Example] In FIG. 50 friends.

7 The diameter of both ends in contact with the flange 6 is k 40 lU, and the inner material is 4 t 50 (after 1 roll, the material 4 is
The winding thickness of □ is almost the same in the center and near the 7 lunge 6.
There was no difference.

[Conventional example]

As shown in FIG.
When the material 4 was wound at 500V, as shown in Fig. 2, the winding thickness of the material 4 was thicker near the 7 lunges 2 and thinner at the center, and the material 4 was wound into a drum shape as a whole. When the material 4 was pulled out from the wound reels 7 and 3, the material 4 could be pulled out smoothly with the reel 7 of the embodiment without any problems, but with the reel 3 of the conventional example. Due to the vibration during conveyance, the material 4 near the 7 langes 2 collapsed to some extent and overlapped the material 4 around the center, so the material 4 could not be pulled out smoothly, and when it was pulled out forcibly, the material 4 collapsed. I got some scratches.

As described in detail above, the wire rod/strip winding reel of the present invention has a body whose diameter is thick at the center and gradually becomes thinner as it approaches the 7 lunges on both end faces, so it is suitable for automatic winding machines. When material is wound up with can be made almost uniform over the entire length of the body, and therefore the material near the 7 lunges will not fall down and pile up on the material in the center during conveyance, so the material can be smoothly pulled out from the reel without any hindrance. It has the excellent effect of not causing scratches on the material.
