Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a winding mechanism for a wire material, and particularly to a suitable method for holding the winding start end of a wire material.

[Background of the invention]

When supplying long wire materials to equipment for the purpose of storing them or performing various wire treatments such as attaching terminals or forming, most wire materials are wound onto reels due to the drawback that the shape of the wire materials cannot be determined. ing.

When winding, the winding start end is held with a clamp attached to the reel before winding begins, thereby making it possible to wind the wire material without slipping.

However, the transfer work, such as moving the end of the wire material to the clamp on the reel and gripping it, and then gripping the end again at the final stage of unwinding, is difficult because the other party is a flexible wire material. Currently, various mechanisms and time are required for positioning and handling, and it is difficult to handle them.

On the other hand, when pulling out a wire material wound on a reel, it is extremely often necessary to pull it out with a constant tension. Normally, the necessary tension is provided by applying a brake to the rotation of the reel, but if there is a distance between the reel and the unit that pulls out and processes the wire, the wire will be pulled out of the clamp on the reel. The disadvantage is that once you leave, you are in a free state and cannot maintain the tension until the end.

The hand that grips the end of the reel is still holding the reel itself.
Alternatively, it is generally installed on a shaft that rotates with the reel, but it supplies the power source to the hand of the rotating part,
Difficulties arise, such as an increase in the inertia of the rotating part.

[Purpose of the invention]

An object of the present invention is that when winding a wire material on a reel, the hand that grips the end of the wire material at the position where the wire material is supplied to be wound onto the reel becomes the winding end on the reel and rotates. The objective is to provide a reel and a hand with a mechanism that allows for

[Summary of the invention]

In the present invention, a clamp for gripping the end of the wire material to be wound onto a reel is attached to the tip of the elongated slide rod.

In addition to sliding, this rod has a structure that allows it to rotate around an axis that is perpendicular to the sliding direction and parallel to the rotation axis of the reel.

The entire slide rod having this structure is referred to as a hand here, and the wire material is transferred with this hand.

The hand is installed near the reel, and the axis of rotation of the reel is placed on the trajectory drawn by the clamp at the tip of the hand as the slide rod rotates.

In this way, the clamp can be moved to the winding core of the reel by the rotational movement of the hand, and the clamp can be temporarily held there if there is a groove provided in the winding core of the reel.

Furthermore, if the clamp and the slide rod are coupled in a rotatable structure, a mechanism can be obtained in which the clamp can rotate integrally with the reel while gripping the wire while imparting sliding and swinging motion to the slide rod.

[Embodiments of the invention]

An embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 is an overview diagram of the present wire material winding mechanism. This figure shows a mechanism that is intended to be attached to a wiring machine, and is mounted on a base plate 1 by using holes 2 and fixing it to the head of the wiring machine with screws.

A reel rotation shaft 3 is installed on the pace 1, and a reel 5 for winding a wire 4 is attached to the tip of the reel rotation shaft 3.

Note that the reel rotation shaft 3 can be connected to an external motor (not shown), and the reel 5 can be rotated thereby.

A hand rotating shaft 6 is installed near the reel 5, and a rotating plate 7 at the tip thereof is attached with a linear bearing 9 that receives a slide rod 8 that is slidable in a direction orthogonal to the rotating shaft. The slide rod 8 has two stoppers 10 that sandwich the rotary plate 7, and a compression spring 11 is inserted between the stopper 10 and the rotary plate 7. As a result, the position of the slide rod 8 usually settles at a position balanced by the two compression springs 11.

The tip of the slide rod 8 is bent into an L-shape and is connected to a clamp 12 that holds the wire 4, but the clamp 12 and the slide rod 8 are connected to each other by a bearing 13 structure that allows them to rotate freely. The slide rod 8, clamp 12, etc. attached before the rotary plate 7 are collectively called a hand.

Now, when this hand having the clamp 12 is rotated together with the rotary plate 7 by the rotary actuator 19, the wire rod 4
If the clamp 12 is gripped, and the axis 3 of one rotation of the reel 5 is placed on this trajectory, the clamp 1
2 can be moved to the vicinity of the winding core 14 of the reel 5.

Further, as shown in the figure, if the reel 5 is provided with a slit 15 and the winding core 14 is provided with a groove 16, the clamp 12 can be housed in the winding core 14 by the rotational movement of the slide rod 8.

The end portion of the wire rod after winding is drawn into the straightening roller 17 of the wire rod 4, a forming unit, etc., and set.

Next, referring to FIG. 2, the operation of the hand section and reel during winding of the wire will be explained.

In FIG. 2(a), the clamp 12 is housed in the groove 16 of the winding core 14 of the reel 50 at the position after gripping the wire 4 at the position by the rotation of the gripping section described above. The clamp 12 can be easily fixed by a gripping mechanism (not shown) of the winding core 14.

As shown in FIG. 2(b), when the reel 5 is rotated to wind up the wire 4, the clamp 12 rotates together with the reel 5, so that it can be wound around the wire 4 without slipping.

At this time, the slide rod 8 connected to the clamp 12 is supported by the linear bearing 9 on the rotary plate 7, and slides by expanding and contracting the compression spring 11. Perform a rotational movement.

In this way, winding is performed with the clamp 12 holding the wire 4 in the first place.

When the wire rod 4 is unwound, the end portion of the wire can be reliably supplied to the next wire rod processing unit by the knot.

In addition, by applying the hand brake 20 to the hand brake 20 on the no-end rotating shaft 6 of the rotary plate 7 shown in Fig. 1 at this time, it is possible to apply the same tension as that applied with the reel brake 21 until just before the next unit. Therefore, it is very effective in drawing out the wire rod 4.

〔Effect of the invention〕

According to the present invention, the wire end is taken out again when the wire end is supplied for winding the wire onto the reel, when the reel is rotated to take up or unwind the wire, and furthermore, when the reel is finished winding, the wire end is taken out again. The end portion is always held by the same clamp, and the wire rod can be delivered quickly and reliably using the reel.
