Description

  The present invention relates to a reel for a metal line body such as a steel cord and a wire, and more particularly, to a reel for a metal line body that can easily lock a reel of a large diameter metal line body.

  Conventionally, a typical reel for a metal wire body mainly composed of a winding drum and a flange has a metal wire Wa that has been wound on a winding drum (not shown) as shown in FIG. In the outer periphery of the flange 104 with a diameter slightly larger than the diameter of the metal filament Wa, and the outside of the flange 104 adjacent to the observation hole 105. The clip-shaped locking tool 110 fixed to the outer peripheral edge at the end face was provided.

  In the above-described prior art reel, the end portion of the metal wire body Wa wound around the winding drum portion is led out from the peep hole 105 and locked by the locking tool 110, so that the locking operation takes time. In addition, the metal wire body Wa exists on the outside of the flange 104. Therefore, the metal wire body Wa is not only obstructed during transportation and storage, but also when the wire wire is disconnected from the locking tool 110. It has to be removed and moved from the peep hole 105 to the winding drum (not shown) side, which requires a lot of work for the wire breaking work.

  The present applicant has proposed a completely new reel for metal filaments in Patent Documents 1 and 2 etc. with respect to this prior art. FIG. 7 is a cross-sectional view of a locking tool according to a reel for a metal filament described in Patent Document 2. The locking tool 120 includes a fixing portion 112, a gripping portion 111, and a bridging portion 113 that connects the fixing portion 112. When the metal wire is locked, the gripping portion 111 protrudes from the peeping hole 115 to the inside of the flange 114. The front end portion of the grip portion 111 has a semicircular U shape in cross-sectional shape, and is used for locking the end portion of the metal filament. According to such a locking tool 120, the end portion of the metal wire wound around the reel can be locked inside the flange 114 of the reel, and the metal is inserted into the lead-out hole provided in the flange as in the prior art. It can be easily locked and disconnected without passing through the wire. This makes it extremely easy to lock and disconnect the metal filaments, greatly improving workability, and a metal filament reel that can be achieved with a very simple device even in automation of these operations. I was able to get it. In addition, as a technique related to the improvement of the reel for the metal wire body, Patent Document 3 discloses a metal wire provided with a gripping stabilizing part together with a gripping part so that the metal wire body is not detached when the reel is transported or stored. A strip reel is disclosed.

However, in the reels for metal filaments described in Patent Documents 1 to 3, there is still room for improvement when locking a metal filament having a large diameter. As described above, when the metal linear body is locked, the bridging portion 113 is integrally deformed together with the grip portion 111, and the grip portion 111 is protruded from the peep hole 115 to the inside of the flange 114. However, the height h ₁ from the outer end surface of the flange 114 of the locking member in the state that does not grip the metal striatum, and it need not exceed the height h ₀ of the outer peripheral bent portion 114 ₀ of the flange 114 Become. That, and when the height h ₁ from the outer end surface of the flange 114 of the fastener is to be stored is higher than the height h ₀ of the outer peripheral bent portion 114 ₀ of the flange 114 and staked reel in horizontally, reel There is a possibility that the locking tool 120 may be caught and damaged when the roll is conveyed on the rail.

  Further, when winding the filament, it is a design restriction that the grip portion 111 does not protrude to the inner end surface of the flange 114. This is because if the grip portion 111 protrudes to the inside of the inner end face of the flange 114, the metal wire body being wound is caught, and there is a concern that the metal wire body may be broken or the locking tool 120 may be damaged.

Due to the above restrictions, it has been difficult to design a metal wire reel that locks a metal wire with a large diameter. That is, when the locking tool 120 is pushed so that the bridging portion 113 is in contact with the outer end surface of the flange 114, the metal wire body has a diameter larger than the gap between the tip of the gripping portion 111 and the inner end surface of the flange 114. The wire cannot be fitted into the grip portion 111, and the metal wire cannot be locked. On the other hand, when the gap between the tip of the gripping part 111 and the inner end surface of the flange 114 is made larger than the wire diameter of the metal strip, the height h ₁ from the outer end surface of the flange 114 of the locking tool 120 is the outer periphery of the flange 114. becomes higher than the height h ₀ of the bent portion 114 _0, failure occurs in the transportation and storage.

Incidentally, it is conceivable to prevent problems transportation and storage by improving the flanges of the reel metal striatum, for this purpose, fastener height h ₀ of the outer peripheral bent portion 114 ₀ of the flange 114 120 it is necessary to flange 114 from the outer end surface height h ₁ or more height. In this case, the outer width of the reel must be increased or the inner width of the reel must be decreased. When the outer width of the reel is increased, all the equipment that uses the reel must be reviewed and modified. When the inner width of the reel is reduced, the winding amount of the metal wire must be reduced accordingly. This is not preferable.

  Therefore, an object of the present invention is to provide a reel for a metal wire body that can easily carry out the reel locking of a large-diameter metal wire body, which has been difficult in the past.

  As a result of intensive studies to solve the above-mentioned problems, the present inventor can solve the above-mentioned problems by making the reel for metal filaments, in particular, the locking device for the metal filaments a specific structure. As a result, the present invention has been completed.

That is, the reel for metal filaments of the present invention has a gripping part for latching the metal filaments, a fixing part fixed to the flange of the reel for metal filaments, and rising from the fixing part. A locking device comprising a bridging portion to be connected is fixed to the outer end surface of the flange of the reel for a metal filament with the fixing portion, and a peeping hole is formed on the outer end surface of the flange so as to face the grip portion. In the reel for a metal striated body that is formed and elastically deformed from the outer side of the outer end surface of the flange toward the inner side so as to be elastically moved to the winding drum side through the peep hole,
When the bridging portion is in contact with the outer end surface of the flange, the gripping portion can be elastically deformed to lock the metal filament, and in a state where the metal filament is not locked, The gripping part does not protrude to the inside of the inner end surface of the flange part,
The grip portion is curved so that a distance between a tip of the grip portion and an inner end surface of the flange is widened, and the inner end surface of the flange does not have a depression. As a result, it is possible to provide a reel for a metal filament that can easily perform reel locking of a large-diameter metal filament that has been difficult in the past. In addition, since the end of the gripping part and the inner end face of the flange are curved so as to be widened, the end part of the metal filament can be easily fitted into the gripping part, and the bending rigidity of the metal filament can be increased. Can be prevented from coming off.

  In this invention, it is preferable that the cross section of the connection part of the said holding part and the said bridge | crosslinking part continues with a curve. Thereby, the stress added to a holding part can be relieve | moderated and durability with respect to elastic deformation can be improved. Moreover, it is preferable that the bridging portion extends in a direction away from the outer end surface of the flange toward the outside as it goes from the fixed end to the gripping portion.

  ADVANTAGE OF THE INVENTION According to this invention, the reel for metal filaments which can perform the reel latching of a large diameter metal filament can be provided easily.

Hereinafter, the present invention will be described in detail with reference to the drawings.
FIG. 1 is a partial side view of a preferred embodiment of a reel for a metal filament according to the present invention, and FIG. 2 is a cross-sectional view of a preferred example of a locking tool according to the present invention. The reel for a metal striated body of the present invention rises from a holding part 1 for locking the metal striated body, a fixing part 2 fixed to a flange 4 of the reel for a metal striated body, and a fixed part. A locking tool 10 composed of a bridging portion 3 to be connected is fixed to the outer end surface of the flange 4 of the reel for a metal linear body with the fixing portion 2, and the peeping hole 5 is provided outside the flange 4 so as to face the grip portion 1. Formed on the end face, the gripping part 1 is elastically deformed from the outer side of the outer end face of the flange 4 toward the inner side so that it can be elastically moved to the winding drum side through the peephole 5.

  In such a locking tool 10, only the gripping part 1 can easily enter the peephole 5 by lightly pressing (F) the bridging part 3, preferably the gripping part 1 side, toward the flange 4. 4, the end portion of the metal wire body wound around the winding body portion 6 is engaged with the grip portion 1 to be locked.

  FIG. 3 is a schematic cross-sectional view when the metal filament is locked by the locking tool according to the present invention. In the present invention, when the bridging portion 3 is in contact with the outer end surface of the flange 4, the grip portion 1 is shown. It is important that can be elastically deformed to lock the metal wire Wb. The conventional locking device grips the metal wire body by elastic deformation of the fixing portion and the bridging portion. As shown in FIG. 7, the grip portion 111 has a U-shaped cross-section at the tip. Since it has a shape and a size of about 3 mm, it is impossible for the operator to elastically deform the grip portion 111 manually. In the present invention, the tip of the grip portion 1 is not U-shaped, but the grip portion 1 is L-shaped, or the tip is curved so that the distance from the flange inner end surface is widened. It is possible to fit the end portion of the metal wire Wb between the flange 4 and the tip of the grip portion 1. Therefore, the grip portion 1 is elastically deformed and locked by the force for pushing the end portion of the metal wire Wb. That is, when the gripping portion 1 moves to the reel drum portion 6 due to elastic deformation of the fixing portion 2 and the bridging portion 3, and the bridging portion 3 contacts the outer end surface of the flange 4, the gripping portion 1 is further elastically deformed. Thus, the metal wire Wb having a large diameter can be locked.

Following the above, when installing the fastener 10 without changing the height of the outer peripheral bent portion 4 ₀ of the flange 4, the gap of the inner end surface of the grip portion 1 of the tip and the flange 4 is the diameter of the metal striatum Wb It may not be satisfied. However, according to the present invention, since the grip portion 1 is elastically deformed, even if the gap between the tip of the grip portion 1 and the inner end surface of the flange 4 is less than the diameter of the metal wire body Wb, This gap can be widened by elastically deforming the gripping part 1 with a force pressed against the gripping part 1. Thus, without changing the height of the outer peripheral bent portion 4 ₀ of the flange 4, it is possible to lock the metal striatum Wb of large diameter. Moreover, since the holding | grip part 1 elastically deforms, it also has the advantage that it can respond to the metal filament Wb of several wire diameter. Furthermore, the locked metal wire Wb is pressed by the elastic force of the gripping portion 1, and the locking is ensured without detachment from the gripping portion 1 due to the bending rigidity of the thick metal wire Wb. It is supposed to be.

  FIG. 4 is a cross-sectional view of a locking tool 20 according to another embodiment of the reel for metal filaments of the present invention. The locking tool 20 extends in a direction away from the outer end surface of the flange 4A toward the outside as the bridging portion 3A moves from the fixed portion 2A toward the grip portion 1A. Even with such a structure, the effects of the present invention can be obtained satisfactorily.

  FIG. 5 is a cross-sectional view of another preferred embodiment of a locking tool according to the present invention. In the present invention, as shown in FIG. 5, it is preferable that the cross section of the connection portion between the gripping portion 1B and the bridging portion 3B is continuous with a curve. By connecting the connecting portion between the grip portion 1B and the bridging portion 3B with a curved surface, the stress applied to the grip portion 1B can be relaxed and the durability against elastic deformation can be improved. Moreover, since the shape of the connection part of the holding part 1B and the bridge | crosslinking part 3B is not sharp, it also has the effect of improving a worker's safety. Furthermore, as shown in FIG. 5, the cross-sectional shape of the grip portion 1 </ b> B is preferably a curved shape that wraps around the metal filament. Thereby, a metal wire body can be latched favorably.

  Further, in the present invention, as shown in FIG. 5, it is preferable that the tip of the gripping portion 1B is curved so that the distance from the inner end surface of the flange 4B is widened. With such a structure, it is possible to easily fit the end portion of the metal striated body into the gripping portion 1B, and to obtain an effect of preventing the metal striated body from coming off due to the bending rigidity.

  In the metal wire reel of the present invention, the size of the locking tool can be appropriately designed according to the size of the metal wire reel used, the wire diameter of the metal wire to be gripped, etc. it can.

  The reel for the metal striated body of the present invention is a reel that locks the metal striate terminal inside the conventional reel, by elastically deforming the gripping part without changing the height of the reel outer circumferential bent part, A large-diameter metal wire body can be locked. The metal wire reel of the present invention eliminates inconvenience at the time of storage and transportation, so that it is possible to automate the reel locking of a large-diameter metal wire, which was difficult with conventional reels. It has the effect of doing.
