Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is directed to the end of a metal wire in a reel for winding a metal wire, which is used to secure the end of a metal wire such as a stranded wire wound on a reel to a reel. The present invention relates to a locking device.

[Prior Art] For example, manufacturers of metal wire such as steel cord wind the manufactured metal wire on a reel and ship it, and the starting end of the metal wire is inserted into a hole drilled in the shaft of the reel. At the same time, the reel is rotated and wound up, and a predetermined length of metal wire is wound onto the reel shaft. It is pulled out to the outside and secured with a clip provided on the outer edge of the flange.

FIG. 6 shows a metal wire end locking device in a conventional metal wire winding reel. As shown in the figure, a hole 33 through which the metal wire is inserted is bored in the outer circumference of the flange 32 of the reel 31, and the winding end portion 34 of the metal wire that has been wound around the reel 31 is inserted into this hole 33. and pull out the winding end portion 34 to the outside of the flange 32.
It is secured to a clip 36 attached to a folded part 35 formed by folding back the end of the flange 32 at its outer surface. This clip 36, as shown in FIG.
A pair of fixing pieces 38 are provided by bending both ends of the base of a U-shaped locking piece 37 at right angles, and the fixing piece 3 is made of an elastic metal wire such as a piano wire.
8, 38 and the proximal end portion of the locking piece portion 37 are fixed by being sandwiched between the folded portion 35 of the flange 32. In this state, the locking piece 37 is attached to the flange 32.
Pressed against the outer surface.

Note that a rising portion 39 inclined diagonally upward is formed at the tip of the locking piece portion 37.

To lock the winding end portion 34 of the metal wire, the winding end portion 34 is passed under the rising portion 39 at the tip of the locking piece portion 37 of the clip 36, and the locking piece portion 37 and the flange are locked. It was inserted between the outer surfaces of the locking piece 32, sandwiched between the two, and locked by the elasticity of the locking piece 37.

[Problems to be Solved by the Invention] However, the above-mentioned conventional device has various drawbacks.

That is, metal wires have different wire diameters, and the clip 36 has a large spring force to cover these diameters. There is a problem in that the spring of the clip 36 is so strong that it is difficult to clip the clip 36 when it is inserted between the portion 37 and the outer surface of the flange 32, resulting in poor workability.

In addition, although the reel 31 is used repeatedly, the spring of the clip 36, which was initially strong, quickly weakens as it is used. If a small item is locked, the locking force may not be sufficient and the reel 31 may become unusable, and even though the reel itself can be used, the clip 36 becomes defective and the reel 31 becomes unusable.

Further, since the spring of the clip 36 is strong as described above, there is a problem in that it crushes the winding end portion 34 of the stranded wire such as the steel cord to be locked, thereby damaging the product.

Further, the end portion 34 of the winding of the metal wire is connected to the clip 36 of the metal wire and the flange 32 of the planar reel 31.
Since it is sandwiched between the outer surface of the metal wire, when tension is applied to the winding end portion 34 of the metal wire, the flange 32
Because the outer surface is flat, it is easy to slip, and the clip 3
Although the spring 6 is strong, there is a problem in that the locking and holding is not always reliable. This becomes noticeable when the spring force of the clip 36 weakens during the process of reusing the reel 31.

In addition, in the conventional device, a rising portion 39 facing diagonally upward is formed at the tip of the locking piece 37 of the clip 36, which has the problem of damaging the packaging materials used during packaging. When the metal wire wound on the reel 31 is visually inspected, the metal wire is conveyed on a roller conveyor in the inspection process, and the winding end portion 34 of the metal wire is stopped when the rising portion 39 collides with the roller conveyor. There is a problem with it coming out.

The present invention solves the various drawbacks of the conventional devices, and it is easy to lock the winding end of the metal wire, and once locked, it is difficult to come off, and it can withstand repeated use. To provide a device for locking the end of a metal wire in a reel for winding a metal wire, which does not damage the metal wire of a product to be stopped and can stably lock regardless of the wire diameter.

[Means for Solving the Problems] The configuration for achieving the above object will be explained using FIGS. 1 to 5 corresponding to the embodiments.
In the metal wire end locking device of the metal wire winding reel of the present invention, an elastic metal wire is wound once to form a first winding portion 8 with one side 10 serving as a mounting portion 9. Then, following the first winding part 8, one side 14 is overlapped on the other side 11 and the metal wire is wound once, so that the other side 15 protrudes on the side opposite to the attachment part 9. The clip 7 having the second winding part 12 protruding as a part 13 is arranged with the first winding part 8 in contact with the outer surface of the flange 3 of the metal wire winding reel 1, and the mounting part 9 is It is characterized in that it is sandwiched in a folded part 6 which is folded back toward the outer surface of the flange 3 at the outer edge of the flange 3.

[Function] In the metal wire end locking device of the metal wire winding reel of the present invention configured as described above, the first winding portion 8 is installed on the outer surface of the flange 3 of the reel 1, and the first winding portion 8 is installed on the outer surface of the flange 3 of the reel 1. Since the second winding part 12 is stacked on the first winding part 8 and the protruding part 13 protrudes from the first winding part 8, a gap 18 is formed between the outer surface of the flange 3 and the protruding part 13. Therefore, the end portion 24 of the winding of the metal wire is inserted through the gap 18 and is locked by being sandwiched between the overlapping portion 19 of the first winding portion 8 and the second winding portion 12.

In conventional devices, the end of the winding of the metal wire is sandwiched between the clip and the outer surface of the flange, and the clip is attached so that it presses strongly against the outer surface of the flange. It was too strong and difficult to insert. In the device of the present invention, the first winding part 8 and the second winding part 12 are continuous, and are like one rigid coil spring, and the first winding part 8
Since the metal wire is sandwiched between the second winding part 12 and the second winding part 12, it is relatively easy to insert the winding end part 24 between the second winding part 12 and the first winding part 8. By determining the elasticity of the clip 7 to the extent that it can be inserted into the winding end portion 2 of the metal wire 23,
4 can be easily locked. Furthermore, since the end portion 24 of the winding of the metal wire 23 is held between the first winding portion 8 and the second winding portion 12, the clip 7 is locked so that it is difficult to come off even if the spring pressure of the clip 7 is not very strong. will be done.

In addition, since the metal wire is not sandwiched between separate members as in the past, but rather the metal wire is sandwiched between a series of coil springs, the locking force decreases to the point that it becomes unusable even if it is reused repeatedly. There's nothing to do.

[Example] Hereinafter, an example of the present invention will be described based on the drawings.

FIG. 1 is a perspective view of a reel provided with a metal wire end locking device according to an embodiment of the present invention, and FIG. 2 is a partial front view thereof. In these figures, 1 is a reel on which a metal wire such as a steel cord is wound, and flanges 33 are formed on both sides of the shaft portion 2. Each of these parts is manufactured by forming steel plates into a predetermined shape and welding them to make them sturdy.

A hole 4 is formed in the shaft portion 2 of the reel 1 for inserting the winding end portion of the metal wire, and a hole 5 is formed in the outer peripheral portion of the flange 3 through which the winding end portion of the metal wire is inserted. A folded part 6 is formed on the outer edge of the flanges 3, 3, and the folded part 6 is formed by curling the end edge toward the outer surface of the flange 3.
A clip 7 is attached to the outer surface of the flange 3 by being clamped between the flange 3 and the flange 3.

As shown in FIG. 3, the clip 7 is made by bending and forming an elastic metal wire such as stainless steel wire or piano wire. 10 forms a first winding part 8 which is used as a mounting part 9, and following this first winding part 8, one side 14 is overlapped on the other side 11, and the metal wire is arranged in approximately one plane. Wrap it around once and attach the other side 15 to the opposite side from the mounting part 9.
forms a second winding portion 12 that protrudes as a protruding portion 13.

That is, the first winding part 8 and the second winding part 12
The first winding part 8 is rectangular and the second winding part 12 is trapezoidal or triangular. Further, following the second winding part 12 , the intermediate part of the first winding part 8 is arranged along the outer end of the second winding part 12 at right angles to the opposing direction of the mounting part 9 and the protruding part 13 . A cross section 16 is provided that crosses over the top, and a bent section 17 is formed at the tip of this cross section 16.

The clip 7, as shown in FIG.
The attachment part 9 is inserted between the folded parts 6 formed outward on the outer edge of the flange of the reel 1, the folded parts 6 are caulked, and the attachment parts 9 are crimped onto the folded parts 6 to be fixed. In this installed state, a gap 18 is formed between the outer surface of the flange 3 of the reel 1 and the protrusion 13 of the clip 7, as shown in FIG. 〓Insert from the gap 18 and insert the first winding part 8 and the second winding part 1
Insert between the overlapping parts 19 of the two. As a result, the winding end portion 24 of the metal wire 23 is locked at two locations in the overlapping portion 19. At this time, the transverse portion 16 and the bent portion 17 act as a stopper to prevent the winding end portion 24 of the metal wire 23 from passing past the overlapping portion 19.

However, the transverse section 16 and the bent section 17 or the bent section 17 are not necessarily required.
Even without these, the end portion 24 of the winding can be sufficiently locked with the 19 turns of the overlapping portion.

In addition, although the clip 7 is attached to the right side of the hole 5 in FIG. 4, it may be attached to the left side, and the winding direction of the clip in the embodiment may also be reversed from that shown. That is, the bent portion 17 may be on the right side.

Further, the shapes of the first winding portion 8 and the second winding portion 12 are not limited to those in the embodiment, but may be circular, oval, rectangular, or various other shapes.

[Effect of the invention] As described above, the metal wire end locking device in the metal wire winding reel of the present invention sandwiches the metal wire between the first winding part and the second winding part. Therefore, by determining the elasticity of the clip to the extent that the end of the winding can be relatively easily inserted between the second winding part and the first winding part, the metal wire The end of the winding can be easily locked, resulting in good workability.

In addition, since the end of the winding of the metal wire is held between the first winding part and the second winding part,
Even if the spring pressure of the clip is not very strong, it is possible to lock the wire so that it does not come off easily regardless of the wire diameter.

In addition, since the metal wire is not sandwiched between separate members as in the past, but instead the metal wire is sandwiched between a series of coil springs, the locking and holding force is so strong that it becomes unusable even if it is reused repeatedly. It does not deteriorate and can be used for a long time, making it economical.

Furthermore, by winding the first and second winding parts on a flat surface, they do not protrude onto the reel flange surface as in the conventional case, which can damage packaging materials or cause clips to collide during transportation during the inspection process. There are no inconveniences such as metal wires falling out, and the practical effects are great.
