DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reel for winding a metal wire such as steel cord or wire, and more specifically, to a metal wire wound around a reel. The present invention relates to a fastener for a strip.

[0002]

2. Description of the Related Art Conventionally, as a general reel R mainly composed of a winding drum portion and a flange, as shown in FIG. 10, a metal wire strip which has been wound around a winding drum portion (not shown). In order to lock the terminal portion of the body W, a lead-out hole 12 of the metal wire W drilled with a diameter slightly larger than the diameter of the terminal portion of the metal wire W near the outer edge of the flange 11; The clip-shaped locking tool 14 fixed to the outer edge folded-back portion 13 is provided on the outer end surface of the flange 11 near the lead-out hole 12.
In the reel R of the above-mentioned conventional technique, the end portion of the metal filament W wound around the winding drum portion is led out from the lead-out hole 12, and the locking tool 14 is provided.
Since it is locked at, the terminal portion exists outside the flange 11, and therefore, it not only interferes with transportation and storage, but also disengages the terminal portion from the locking tool 14 when breaking the wire,
Furthermore, it has to be moved from the lead-out hole 12 to the winding drum portion side, which requires a lot of work for the wire unwinding work.

Further, when inserting a twisted metal filament W such as a steel cord into the lead-out hole 12, the end of the end portion of the steel cord is usually separated, In this case, it is necessary to correct the tip. Therefore, it is difficult to automate the guiding and guiding of the tip of the terminal portion to the guide hole 12, and there is only a manual method, which is a heavy work load. It was

Further, by using the metal filament W wound up by the reel R as described above, the metal filament W from the reel R in the rolling process for producing a composite such as rubber represented by a tire. When the end portion of the metal wire W when unwinding is passed through the outlet hole 12, the metal wire W wound around the reel R that is continuous at the winding end end has an elastic force. In many cases, the winding is loose.

Therefore, when the metal wire W passed through the lead-out hole 12 is pulled out from the reel R, there is a case where the metal wire W passes below the continuous loose metal wire W and is drawn out. In this case, in this case, the metal wires W intersect, that is, the metal wires W are entangled and pulled out, and there is a problem that the metal wires W are disconnected in the rolling process.

The applicant of the present invention has proposed a reel for a metal striatum that is completely new from the prior art in Japanese Patent Application No. 3-353237. According to this invention, the metal wire strip is a reel that can be easily locked and released without passing the metal wire strip through the lead-out hole provided in the flange as in the prior art. Since it can be locked and released while tension is applied to the metal wire, the metal wire wound around the reel does not loosen, so the metal wire is not entangled and wire breakage can be prevented. It has a very convenient structure with greatly improved performance.

FIG. 11 is a sectional view of the previously proposed reel R for a metal filament body, and FIG. 12 is a similar sectional view showing its function. In the figure, 21 is a flange, and 22 is a peephole drilled in the flange 21. The locking device 20 includes a fixing portion 23, a grip portion 24, and a bridging portion 25 connecting the grip portion 24. The bridging portion 25 is elastically deformed together with the grip portion 24 only when the metal filament W is locked. Then, the gripping portion 24 is projected from the peep hole 22 to the inside of the flange. That is, when the metal wire W is wound up, the locking tool 20 is not on the inner end surface of the flange 21, so that the metal wire W does not contact the locking tool 20. It can be wound up.

However, there is a case where further improvement is necessary, and by integrally deforming the bridge portion 25,
The force required for the elastic deformation becomes large, and further, when the metal filament W is wound up to the center or more of the peephole 22 as shown in FIG. 11, the elastic deformation of the bridge portion 25 to the inside does not occur. Since it becomes difficult and the grip portion 24 does not protrude inward, the metal wire W cannot be locked. Therefore, the winding amount of the metal filament W on the winding drum portion must be reduced by that much. Even when the metal wire strip is unlocked (when the wire is released), the locking direction of the metal wire strip and the fixing direction of the locking tool are substantially at right angles, so the locking tool is Some point out that it is easily deformed.

[0009]

SUMMARY OF THE INVENTION The present invention is a further practical improvement of the present invention, and the ease of locking and unwinding and the amount of metal wire wound around the reel are reduced. In addition to providing a sufficient security, the present invention provides a reel in which the locked metal filament does not come off during transportation or storage.

[0010]

In order to achieve the above object, a reel for a metal filament according to the present invention has the following structure. That is, the gist of the present invention is to provide a metal wire strip reel.
A fixing portion fixed to the flange of the metal shell, a bridging portion rising from the fixing portion, and a locking member having a hanging portion formed at the tip of the bridging portion. It is fixed near the outer edge of the end face in a substantially tangential direction of the outer edge of the reel, and a slightly larger peep hole is formed on the outer end face of the flange facing the hanging part of the locking tool. Elastically deform from the outside of the outer end face toward the inside,
A gripping portion is formed on the hanging portion so as to be able to resiliently move toward the winding drum portion side through the peephole, and to lock the metal filament in the longitudinal direction of the locking tool by locking. A reel for a metal filament is provided.

A specific example of the technical concept will be described in detail. A fixing portion fixed to the outer end face of the flange of the metal wire strip reel, a bridge portion rising from the fixing portion, A hanging part is formed at the tip of the part, and a horizontal cutting part facing inward from one edge of the hanging part, and a vertical cutting part facing the vertical direction of the hanging part inside the horizontal cutting part, At least one of the hanging portions facing the horizontal cutting portion is bent to form a grip portion of the metal filament, and the locking tool is provided near the outer edge of the outer end surface of the metal filament reel with the fixing portion. The rail is fixed approximately in the tangential direction of the outer edge, and a slightly larger peep hole is formed in the flange outer end surface so as to face the hanging part of the locking tool, and the hanging part is located inside the outside of the flange outer end surface. It can be elastically deformed toward, and can be elastically moved to the winding drum side through the peep hole. The present invention relates to a reel for a metal striated body, characterized in that the hanging parts facing the horizontal cutting part are formed with slightly opened gripping parts on opposite sides. It is possible to use a locking tool that uses a stopper and, in some cases, has a recess formed in at least one edge of the hanging part facing the horizontal cutting portion to insert the metal filament. In some cases, the fixing part of the locking tool may be inserted between the flange of the reel and the outer edge folded-back part to fix the locking tool.

As another specific example, a fixed portion fixed to the outer end surface of the flange of the metal wire reel, a bridge portion rising from the fixed portion, and a J-shaped cross section at the tip of the bridge portion. A hanging tool having a downwardly extending hanging portion and a lower curved portion of the hanging portion forming a gripping portion of the metal filamentary body, and the fixing portion being used to hold the outer end surface of the metal filamentary reel. The reel is fixed near the outer edge in a direction substantially tangential to the outer edge of the reel, and a slightly larger viewing hole is formed on the outer end surface of the flange so as to face the bent portion of the locking tool. A metal filament reel is characterized in that it is elastically deformed from the outer side of the outer end surface toward the inner side so that it can elastically move to the winding barrel side through the peep hole. It is provided.

In the above specific example, the hanging portion is formed integrally with the bridging portion and the tip thereof is bent or formed by attaching a bracket material to the tip of the bridging portion. .

[0014]

According to the present invention, since the locking member is fixed near the outer edge of the reel, the amount of winding of the metal filament increases, and when the metal filament is gripped, it is fixed. Since the metal filament is gripped in the longitudinal direction of the locking device, the disadvantage that the direction of the locking device moves or is deformed by the external force applied during use, especially when breaking the wire, is eliminated. It was decided to be done. Explaining with a specific example, the hanging part at the tip of the locking tool is divided into upper and lower parts, which are provided for gripping the metal striated body. The structure is simple and the metal striated body is provided. Can be securely grasped in a predetermined direction, and since the locking tool of the present invention can be fixed in the vicinity of the outer edge of the flange of the reel, the metal linear member The amount of winding around the winding drum is also sufficient. To further characterize the above example,
A narrow, so-called slit-shaped peephole may be formed at a right angle to the winding direction of the metal filament, so that the end of the metal filament may be located closer to the outer end face of the reel flange than the peephole. It will no longer stick out.

The end portion of the metal filament is locked by the above-mentioned locking tool and is 10 to 20 more than the locking portion of the metal filament.
By cutting at a position longer by cm, workability and automation of locking and unwinding become easy. However, this 10 to 20 cm
The long metal filaments protrude from the outer edge of the reel, and in handling such as transportation and storage, when the external force is applied to the protruded metal filaments, the metal filaments may come off from the locking member.
This is because the locking of the metal linear member by the locking device has a structure that is easily disengaged along the flange wall, and in order to solve this problem, in the present invention, along the flange wall, The metal linear body is elastically gripped from above and below (left and right) so as to be hard to come off.

In order to fix the locking tool to the outer end face of the flange of the reel, the fixing portion of the locking tool is welded, spot welded, screwed to the outer end face, or the locking tool is fitted to the folded portion of the flange outer edge. You may be able to combine. When the locking tool is made removable, it can be replaced with a locking tool that fits the diameters of the metal filaments wound around the reel. Further, the color of this locking tool may be the same as the color of the flange, or may be a different color so as to make it easy to visually recognize the position when locking and releasing. Further, in automation, it is possible to provide electromagnetic characteristics different from those of the flange for position detection. It is important that the maximum height of the bridging portion of the locking device from the flange surface is lower than the folded portion of the outer edge of the flange, and if it is higher than that, the gripping force of the gripping portion when the reels are stacked is increased. May become loose and the lock may loosen.
