Abstract

PROBLEM TO BE SOLVED: To reduce the size of an eye hole to secure the winding amount of a metal filament on a reel by raising the bridging part of a locking means from a fixed part, and projecting only a gripping part inward easily through the inside of a small eye hole to lock the terminal part of the metal filament. SOLUTION: A locking means A is formed by a plate spring material and comprises a fixed part 1, a bridge part 2 raised from the part, and a gripping part 3 obliquely suspended from the bridge part 2. The fixed part 1 is welded on the outer end face of a flange 4 of a reel R, and the gripping part 3 is opposite to a small eye hole 5 formed in the flange 4. When the gripping part 3 side of the bridge part 2 is slightly pressed F1, the gripping part 3 enters the eye hole 5. When the terminal part Wa of the metal filament wound round the winding drum part 6 is fitted to the gripping part 3, and pressing force is released, the terminal end part Wa of the metal filament is clamped by the gripping part 3 and the inner surface of the flange 4 and locked. Thus, the size of the eye hole 5 can be reduced so as to secure the winding amount of the metal filament on the reel.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reel on which a metal filament such as a steel cord or a wire is wound, and more specifically, to a terminal of a metal filament wound on a reel. It relates to a stop structure.

[0002]

2. Description of the Related Art Conventionally, as a general reel R mainly comprising a winding drum and a flange, as shown in FIG. 9, a metal wire W having been wound around a winding drum (not shown) is used. In order to lock the terminal portion Wa, a lead-out hole 12 of a striated body formed in the outer peripheral portion of the flange 11 with a diameter slightly larger than the diameter of the terminal portion Wa of the metal striated body W; And a clip-shaped locking member 14 fixed to the outer peripheral edge 13 of the outer end surface of the flange 11 close to the flange 11.

[0003] In the above-mentioned conventional reel R, the terminal Wa of the metal wire W wound around the winding drum is led out from the lead-out hole 12 and is locked by the locking member 14. The terminal part Wa is present outside the flange 11, and thus not only hinders the transportation and storage, but also removes the terminal part Wa from the locking member 14 when the wire is unwound, and the winding drum from the lead-out hole 12. Had to be moved to the department side, and the wire breaking work was troublesome.

[0004] In inserting a metal wire W such as a steel cord into the lead-out hole 12, the tip of the end portion Wa of the steel cord usually has many loose cases. It needs to be modified, so that the terminal unit W
It is difficult to automate the operation of guiding the leading end to the lead-out hole 12, and there is only a manual method, which is a large work load.

[0005] Further, using the above-described metal filament W wound on the reel R, an operation of pulling out the metal filament W from the reel R in a rolling process for producing a composite material such as rubber represented by a tire. In the above, when the terminal portion Wa of the metal wire W at the time of unwinding is passed through the inside of the lead-out hole 12, the metal wire W wound around the reel R continuous to the end of winding is wound by its elastic force. Are often loose. Therefore, the outlet hole 12
When the metal wire W passed through the wire R is pulled out from the reel R, there is a case where the metal wire W passes under the continuous loose metal wire W and is pulled out. In this case, the intersection, that is, the metal wire W They are entangled with each other and pulled out, and there is a problem that the metal wire W is disconnected in the rolling process.

[0006] A metal wire W wound around the winding body of the reel R
The technology for locking the terminal section Wa is proposed in, for example, Japanese Utility Model Laid-Open No. 3-62069. However, in such a technique, the terminal Wa of the metal filament W
A reel R in which a part of the long hole which can be extracted is perforated along the outer peripheral edge of the flange, and a locking piece is provided on the outer end face of the flange close to the long hole. Even if the required number of steps can be omitted, the metal wire has to be passed through the long hole as in the past when locking, and there is a disadvantage that the number of steps is still required. There is a disadvantage that the wound cord is easily loosened and the cord is easily detached from the locking piece.

[0007] The present applicant has proposed a reel for a metal filament that is completely new to this prior art (Japanese Patent Application No. Hei 3-353).
237). According to the invention, the metal wire can be easily locked without passing through the lead-out hole provided in the flange,
It is a reel that can be unwound, and is extremely convenient with greatly improved workability.

However, there is still a need for further improvement. FIG. 10 is a cross-sectional view of a previously proposed reel R for a metal filament, and FIG. 11 is a similar cross-sectional view showing its function. In the figure, 21 is a flange, and 22 is a peephole drilled there. And the locking tool is the fixing part 23, the grip part 24,
When the metal filament W is locked, the bridging portion 25 is integrally deformed together with the grip portion 24 so that the grip portion 24 projects from the viewing hole 22 to the inside of the flange. Will do. That is, the holding portion 24 of the locking tool is
At the time of winding the metal wire W, since the locking tool is not at least on the inner end surface of the flange 21, the metal wire W can be wound without contacting the locking tool. However, by integrally deforming the bridging portion 25, the deformation force is increased, and the shape of the viewing hole 22 must be increased. Further, as shown in FIG. 10, when the metal filament W is wound around the center of the viewing hole 22 or more, the bridge 2
5 becomes difficult to be deformed inward, and it becomes impossible to protrude the grip portion 24 inward. Therefore, the amount of winding of the metal filament must be reduced accordingly.

[0009]

SUMMARY OF THE INVENTION The present invention is a further practical improvement of the present invention, which can be operated with relatively small force, and has a very small viewing hole formed on the flange surface.
An object of the present invention is to provide a reel having a feature that a sufficient amount of winding of a metal wire around the reel can be ensured.

[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, a metal wire including a grip portion for locking the metal filament, a fixing portion fixed to the outer end surface of the flange of the metal filament reel, and a bridge portion rising from the fixing portion and connecting these. A locking member for locking the strip is provided with the fixing portion fixed to the outer end surface of the flange of the metal wire strip reel, and a peeping hole having a slightly larger shape facing the grip portion is formed outside the flange. Formed on the end face, the grip portion is elastically deformed inward from the outside of the flange outer end face,
A metal filament strip reel, characterized in that it has been made to be able to elastically move toward the winding drum section side through the viewing hole,
Preferably, the bridge portion rises from the fixing portion and extends in a direction away from the outer end surface of the flange to the outside. It is particularly preferable that the gripping portion is provided on a reel for a metal filament having a shape bent substantially perpendicularly to the flange from the bridging portion.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The most characteristic feature of the present invention is that the cross-linking portion is raised from the fixing portion.
The elasticity of the bridging portion is increased, and only the grip portion can be easily protruded inward from the inside of the viewing hole. Therefore, when winding the metal linear body, it is sufficient that only the viewing hole is not filled, and a sufficient winding amount can be secured. Especially,
In the case where the bridge portion extends toward the outside of the flange from the fixing portion, this elasticity is particularly large and is preferable.
