Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a winding machine used for forming long wire splices.

[Conventional technology and its problems]

Long splices are commonly used as a means or method for splicing wire ropes in a straight or endless manner. This long splice is usually done by untwisting the ends of both wire ropes to be connected, dividing them into two groups of long and short strands, untwisting the short strands, and then replacing the other long strand, making both the long and short strands a fixed length. It is obtained by repeating the process of removing the core of the wire rope after cutting and straightening it, and inserting a strand into this part, but since the strand to be inserted has a smaller diameter than the core that was removed, The process involves closely wrapping thread or thin fiber rope around the outer circumference of the strand (seki-maki).

Regarding this side winding, in the past, after fixing one end of the thread or fiber rope for side winding (hereinafter referred to as the side winding strip) to the strand, the side winding strip was unwound from the bobbin and spirally wrapped around the outer periphery of the strand with the fingers. The method used was to wrap it in a shape.

However, this method is entirely manual, and requires considerable skill and precise coordination between multiple personnel to wrap the sekimaki strip closely around the outer periphery of the strand. Twisting occurs easily, and gaps and overlaps occur between the strips for winding, which requires time and effort to adjust.
Therefore, apart from small diameter wire ropes, when using large diameter wire ropes, there was a problem in that the workability and efficiency of side winding were very poor.

[Means for solving problems]

The present invention solves the above-mentioned problems and allows the winding work for long splices to be performed without the need for skill.
The aim is to provide a means that can be carried out reliably and easily even by one person, and its feature is that the bobbin of the strip for winding is attached to the outer periphery of the strand so that it can be moved in the axial direction of the strand. A hollow shaft to be fitted, a rotary operating handle fixed to the outer periphery of the end of the hollow shaft, a drawer guide attached at intervals to a support member extending from the rotary operating handle in parallel with the hollow shaft, and a side opposite to the supporting member. an alignment guide fixed to the alignment guide, a winding guide attached to the tip of the hollow shaft to guide the side winding strip aligned with the alignment guide to the strand, and a tension adjustment that presses the bobbin from the rear end side of the hollow shaft. The structure is equipped with members.

〔Example〕

Embodiments of the present invention will be described below with reference to the accompanying drawings.

Figures 1 to 3 show an embodiment of the winding machine for wire rope splices according to the present invention. In Figure 1, one strand has already been inserted in place of the core rope, and the remaining strand is It shows the state of performing sekimaki.

In the drawings, reference numeral 1 denotes a hollow shaft, which has an inner diameter that allows it to move in the axial direction of the strand b extending from the wire rope B, and an outer diameter that is sufficient to fit the bobbin 3 on which the side-wound strip a is wound. .

In order to be able to simultaneously wind multiple strips a, the hollow shaft 1 has a length equal to or longer than the sum of the lengths of multiple bobbin bodies, and a fixing nut is attached to the rear end. Male thread part 14 screwed into 13
However, a groove 17 is formed in the longitudinal direction for locking a push screw 16 of a spacing ring 15 interposed between the bobbins.

Reference numeral 2 denotes a rotating handle fixed to the front end of the hollow shaft 1. The rotating handle 2 is provided with a support member 4 parallel to the hollow shaft 1. Ring-shaped drawer guides 5, 5 are disposed at different angles.

Reference numeral 6 denotes an alignment guide fixed on the side opposite to the support member 4, and has a hole or groove 12 for guiding the side-wound strip a bent by the drawer guides 5, 5 in a direction perpendicular to the axis of the strand.

Reference numeral 7 denotes a cylindrical winding guide that guides the side-wound strips a aligned in parallel by the alignment guide 6 to the outer periphery of the strand, and is made of a material with a small coefficient of friction such as plastic and has dimensions according to the diameter of the target strand. , is removably attached to the mouth end 11 of the hollow shaft 1 via a fitting part 9, and a tapered slit 10 is formed in the peripheral part.

8 is a tension adjustment member for applying appropriate tension to the side winding strip a pulled out from the bobbin 3;
It is made of an elastic material such as a coil spring and is interposed between the spacing ring 15 and the fixing nut 13.

In other drawings, 18 is a sub-guide provided between the alignment guide 6 and the winding guide 7;
A cylindrical guide 9 is detachably fitted to the rear end of the hollow shaft 1 and has an inner diameter corresponding to the strand diameter.

Next, to explain how to use the present invention, first, the bobbin 3 on which the side-wound strip a of the required diameter has been wound is externally fitted from the rear end of the hollow shaft 1.
is positioned in contact with the rotary operation handle 2. When there are a plurality of bobbins 3, a spacing ring 15 is arranged between the bobbins 3, and the push screw 16 is rotated to engage the tip with the groove 17 of the hollow shaft 1.

Next, after fitting the tension adjustment member 8 into the hollow shaft 1, the fixing nut 13 is screwed into the male threaded portion 14 at the rear end of the hollow shaft 1, and the tension is applied so as to obtain a pressing force to the extent that the bobbin 3 does not rotate freely. Tighten the adjustment member 8. A winding guide 9 and a cylindrical guide 19 are attached to both ends of the hollow shaft 1 in accordance with the diameter of the strand to be applied.

As the assembly is completed above, next, pull out the side-wound strip a from the bobbin 3, guide it toward the rotating operation handle through the corresponding pull-out guide 5 of the support member 4, and lead it out via the alignment guide 6. do.

Then, the strand b inserted in place of the core of the wire rope B is passed through the inside of the hollow shaft 1 from the winding guide 7 side, pulled out from the rear end, and the strand end is fixed with a vise or the like. In this state, the hollow shaft 1 is moved along the strand b until the winding guide 7 reaches the position where the round winding is scheduled to start.

Next, the cross-wound strip a is further pulled out, passed through the slit 10 of the winding guide 7 in the order in which it was pulled out from the bobbin, and is wound an appropriate number of times around the outer periphery of the strand b near the winding guide 7, and then the end of the cross-wound strip is glued. Secure with tape.

The preparations are now complete, and all that is left to do is to move the entire machine along strand b while rotating the rotary operation handle 2 in the direction of feeding out the side winding strip a, and the side winding strip a is moved from the bobbin 3. The direction is changed by the drawer guide 5 and guided in the axial direction of the strand, and the direction is changed by the alignment guide 6 in a direction perpendicular to the axis of the hollow shaft 1, and the strands are aligned at regular intervals so as to be parallel to each other,
It passes through the winding guide 7 and is wound around the strand b, and is continuously and closely wound as it moves in the axial direction of the strand of the machine.

At this time, since the bobbin 3 is pressed by the tension adjustment member 8, even if there are a plurality of bobbins, a moderate and equal brake is generated on the rotation of each bobbin, and a good back tension is given to the side winding strip a. . Moreover, its strength can be adjusted at any time by tightening the fixing nut 5. Therefore, there is no loosening of the side-wound strip body a, which is supplied to the strand b in a moderately tensioned state, and can be tightly wound around the outer periphery of the strand b.

By changing the number of bobbins 3 installed, you can freely wind from single thread to multiple thread winding.
Furthermore, it is possible to accommodate various strand diameters simply by replacing the winding guide 7 and the cylindrical guide 19 on the hollow shaft 1.

[Effect of idea]

According to the present invention described above, the strips for cross-wrap are wound tightly around the outer periphery of the strands by simply rotating the strand while moving along the strand as a guide. It is possible to easily carry out cross winding work without requiring any skill, and in particular, it can facilitate and streamline this kind of work for large diameter wire ropes.It also has a simple structure and is simple. Excellent effects can be obtained, such as the ability to freely perform strip winding and double thread winding.
