DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a reel for winding a metal wire (hereinafter simply referred to as "reel") for winding a metal wire such as a steel wire, a steel cord and an electric wire, and more particularly to a steel cord for reinforcing a tire. And a reel suitable for winding the reel.

[0002]

2. Description of the Related Art Conventionally, as a structure for winding a metal wire on a reel and fixing the end of the metal wire when it is fully wound, as shown in FIG. Hole 34
And a reel 31 provided with a stopper 35 made of a steel wire or a leaf spring on the outer surface of the flange in the vicinity of the small hole 34
There is a general, this was wound around a metal striatum W to the reel 31, is sandwiched between the fastener 35 and the flange outer surface of the metal striatal end W _0, derived from the small holes 34 I was doing it. The flange 32 is provided with a large number of reinforcing ribs 33 formed by pressing. In addition, the outer periphery of the flange is bent outwardly in a round shape so that the outer peripheral edge portion 32a
Are formed.

[0003] In the reel 31, troublesome with the work through the small hole 34 of the metal striatal end W ₀ during the locking, it is troublesome to work to take out the end even at the time of the solution lines. Also, when the metal wire is a stranded wire such as a steel cord or a wire rope, the ends are separated,
There is a problem that it is difficult to pass the wire through the small hole 34. Therefore, it is necessary to wind the end portion with a tape or to melt and fuse the element wires, and the operation is very complicated.

[0004] In a rubber coating step (calendering step), which is one of the intermediate steps of tire production,
Usually, a steel cord is fed from 500 or more reels. At that time, the work of unwinding the ends of the steel cords from the fasteners is performed simultaneously. Therefore, at the time of wire breaking, it is required to shorten the working time in seconds.
The reel 31 could not meet this demand.

Japanese Patent Laid-Open Publication No. Hei 6-107377 discloses a reel aiming at eliminating the above-mentioned complicated operations of the locking operation and the wire breaking. The reel 41 disclosed in this publication is
As shown in FIGS. 9 (a) and 9 (b), an end locking device 45 is provided which has a grip portion 44 having a grip portion 44 at the front end thereof, the grip portion 44 being able to protrude and retract into a viewing hole 43 formed in the flange 42. 45
Is elastically deformed by pressing inward from the outside of the outer end face of the flange, and the
Of the metal wire end W ₀
Then, the pressing force is released to lock the end of the metal filament.

However, in the reel 41, since the end locking member attached to the outer end face of the flange protrudes more than the outer end face of the flange, the reel 41 is used for handling such as packing / transportation of product reels or for stacking. In this case, when the operator's hand or the flanges of the reels come into contact with each other, the end locking member is pushed, and an accident occurs in which the end of the metal filament comes off from the end locking member. Also, as a locking operations when fully wound, while "pushing the end fastener 35 'with one hand, cooperative operation of" the metal striatal end W ₀ fitted to the grip portion "on the other hand It is inevitable and the workability is poor.

In view of the above, the present applicant has proposed a new type of reel as disclosed in Japanese Utility Model Registration No. 30034040 with respect to the above-mentioned conventional technology. This reel 51
As shown in FIGS. 10 (a) and (b),
In a reel having flanges 53 fixed to both ends of the reel, mounting grooves 54 are provided on the inner surface of the flange in the radial direction to the outer peripheral edge of the flange, and end locking members 55 made of a flat metal plate are installed in the mounting grooves 54. The base end of the end locking member 55 is integrally fixed at the fixing portion B, and the end of the metal filament is sandwiched between the mounting groove 54 and the end locking member 55. .

However, according to the structure of the reel 51, FIG.
As shown in 1, when the gap between the mounting groove 54 and the end fastener 55 draws deep end W ₀ of the metal striatum, end fastener 55 is warped greatly in the direction of the arrow, the plastic deformation Resulting in. In this case, the reel cannot be used repeatedly, and the life of the reel is shortened.

[0009]

SUMMARY OF THE INVENTION The present invention has been made to solve the problems of the various conventional reels described above, and the end of the metal wire can be easily formed without shortening the life of the reel. It is an object to provide a reel that can be locked and unwound.

[0010]

In order to solve the above-mentioned problems, a reel for winding a metal wire according to the present invention is further improved based on a reel 41 (utility model registration No. 30034040) shown in FIG. That is, in at least one location on the inner surface of the flange provided at both ends of the winding drum, a mounting groove is provided in the radial direction to the outer peripheral edge of the flange, and the mounting groove is formed of an end portion made of a metal elastic body. In the reel in which the locking tool is fitted and the base end of the end locking tool is fixed to the flange, a restricting portion projecting above the end locking tool is drilled in the mounting groove. An end locking member is provided so as to be loosely inserted into the insertion hole and protrude outside the flange.

With the above configuration, the following operation is produced. First, since the restricting portion of the end locking member protrudes outside the flange from the insertion hole of the mounting groove, when the end of the metal filament is sandwiched between the mounting groove and the end locking device, The restricting portion serves as a so-called stopper, and the end of the metal filament is not drawn deep into the gap between the mounting groove and the end locking member. In addition, since the end locking device is provided on the inner side of the flange, when the metal wire is fully wound around the reel, the center of the end locking device is hidden by the winding surface, Even if the restricting portion is pushed by an external force, the end locking member comes into contact with the winding of the metal filament, and the movement of the tip of the end locking member into the reel is suppressed to some extent. Furthermore, if the restricting part is pushed in from the outside of the flange with a finger or a jig, a gap is formed between the tip of the end locking tool and the mounting groove. Is locked.

Further, since the end locking member is made of a metal elastic body, it is subjected to a deformation action within a range not exceeding the elastic limit at the time of locking and releasing the end of the metal filament. For this reason, when the metal filament is fully wound, the end of the metal filament is sandwiched between the end locking member and the flange so that the end of the metal filament is elastically deformed by the end locking member. Fixed by the pressing force of Further, at the time of wire breaking, the edge of the metal wire is easily broken by simply pulling the edge of the metal wire slightly upward.

In the reel having the above-mentioned structure, it is preferable that the end of the end locking member bend outwardly along the outer peripheral edge of the flange. This is because, at the time of reel winding or reeling out, the metal filament does not rub or catch on the end locking member. Further, it is preferable to provide a slight gap between the front end of the end locking member and the flange. This is because the end of the metal filament can be more easily sandwiched between the end locking member and the flange. By the way, it is sufficient that the length of the restricting portion has a length that can protrude from the insertion hole to the outside of the flange, but the tip of the restricting portion is positioned at the same position as or slightly inside the contour of the outer peripheral edge of the flange. By doing so, unnecessary contact with the regulating portion during handling of the reel is prevented.

[0014]

BEST MODE FOR CARRYING OUT THE INVENTION The end locking member is made of a highly elastic metal and has a thickness of about 0.4 to 1 mm and a width of 5 to 10 mm.
A flat plate having a thickness of about mm is preferable. And if you want to change the pressing force according to the type and diameter of the metal filament
The thickness, width, and material of the flat plate may be appropriately changed. Also, the mounting groove may be provided by extending one of the reinforcing ribs radially provided on the flange to the outer peripheral edge of the flange, or may be provided at a location different from the reinforcing rib. The depth of the mounting groove needs to be larger than the thickness of the end locking member. In addition, the fixing between the base end of the end locking member and the mounting groove is usually performed by spot welding, but other fixing means such as fixing with a metal adhesive, bolts and nuts, fixing with screws, and the like are also used. be able to.

If the tip of the end locking member is rounded by chamfering or is tapered by pointing, the end of the metal filament does not catch on the end locking member. Locking and unwinding can be performed more smoothly. Further, if the tip of the end locking member is subjected to a suitable plastic processing or deformation processing such as a projection or a small wave shape, the locking of the end of the metal wire body is further ensured.

It is also conceivable that the shape of the mounting groove is devised to smoothly introduce and lead out the end of the metal filament. For example, it is preferable to expand the groove shape above the mounting groove in the outer peripheral edge of the flange in a fan shape to be a guide portion, or to provide a means for inclining the mounting groove so that a gap between the end portion of the end locking tool and the mounting groove becomes large. It is.

Further, the present applicant has disclosed in Japanese Patent Application Laid-Open No. 9-263360.
As disclosed in Japanese Patent Laid-Open Publication No. H06-32, a mounting hole is provided at the end of the mounting groove, the base end of the end locking tool projects from the mounting hole to the flange outer surface, and the base end and the flange outer surface are abutted and fixed. May be. With this configuration, when the end portion of the end locking member is bent, the contact portion between the mounting hole and the end locking member becomes a fulcrum and is bent, so that the life of the fixing portion can be extended. .

As the material of the reel (winding drum and flange), carbon steel for general structure, special steel, cast steel or the like can be used as appropriate. The mounting groove and the guide portion of the flange can be formed by pressing or grinding.

[0019]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a reel according to the present invention will be described below with reference to the drawings. (Example 1) As shown in the sectional views of FIGS. 1 and 2, a reel 1 was produced by providing flanges 3 and 3 at both ends of a winding drum 2. A large number of reinforcing ribs 4 are radially provided on the flange 3 by press working. The reinforcing ribs 4 are raised on the outer surface of the flange, and conversely, recessed on the inner surface of the flange. The outer periphery of the flange is folded round to form a flange outer peripheral edge 3a for reinforcement. Then, one of the reinforcing ribs was extended to the outer peripheral edge of the flange by press working to form the mounting groove 5. An end locking member 6 for locking the end of the metal filament is installed in the mounting groove 5.

As shown in FIG. 2, an insertion hole 7 penetrating through the flange is provided above the mounting groove 5 near the outer periphery of the flange.
Was provided by press punching. Further, a restricting portion 8 having a length capable of bending a part of the end locking member and protruding to the outside of the flange is provided above the end locking member 6. Then, the restricting portion 8 is loosely inserted into the insertion hole 7 with the flange protruding outside the flange, and the base end portion 6b of the end locking member and the flange are fixed at the fixing portion B by spot welding, and a desired reel is formed. Was configured.

FIG. 3 is a perspective view of the end lock 6. Width 1
A flat steel wire for a spring having a thickness of 0 mm and a thickness of 0.5 mm is used, and a tip portion 6a is subjected to a sharpening process so as to be tapered. Also,
The restricting portion 8 was formed by bending a flat steel wire at a position near the distal end portion 6a. After all these processes were completed, the whole was subjected to heat treatment to impart elasticity and strength.

FIG. 4 shows the operation of the end locking device. When the restricting portion 8 protruding outward from the flange is pushed in with the finger F, the end locking member bends inward with its base end 6b as a fulcrum, and the gap S between the distal end 6a and the flange outer peripheral edge 3a increases. As a result, the end of the metal filament can be easily introduced. Thereafter, when the finger is released, the end locking member is restored by elasticity, and the end of the metal filament is securely fixed. FIG. 5 shows a state in which the metal wire W is actually wound up using the reel 1 described in detail with reference to FIGS. 1 to 4, and the end W ₀ is sandwiched between the end locking members 6.

Example 2 An end locking member 9 as shown in FIGS. 6A and 6B was manufactured. This has a structure in which the regulating portion 11 is separately manufactured and combined with the end locking member 9. This end locking member 9 is formed by using a flat steel wire for a spring similar to that of the first embodiment, and is tapered at one end so as to have a curved tip 9a.
And a fitting hole 10 is provided at a position close to the distal end portion 9a. A fitting portion of the metal regulating portion 11 having a head portion 11a and a fitting portion 11b at both ends in the fitting hole 10 is provided. 11b was formed so as to be fitted and fixed. Then, the end locking member 9 is set in the mounting groove of the reel, and the restricting portion 11 is loosely inserted into the insertion hole 13 provided in the flange 12, so that the base end portion 9b of the end locking member and the flange 12 are connected. Is fixed by spot welding B
To form a desired reel. In this embodiment, if the head 11a of the restricting portion 11 is made larger than the diameter of the insertion hole 13, the head hits the flange and stops. Therefore, the end locking member 9 does not warp more than necessary, and the life of the end locking member can be extended.

(Embodiment 3) In the reel 14 shown in FIGS. 7 (a) and 7 (b), the shape of the mounting groove 16 provided in the flange 15 and the shape of the end locking member 17 are further devised. This is an example in which a means for fixing the base end of the locking tool is devised. That is, a guide portion 16a is formed in the mounting groove 16 so as to expand in a fan shape at the flange outer peripheral edge portion 15a. Further, a projection 21 is formed on the tip end portion 17a of the end locking member 17. Further, a mounting hole 18 was formed at the end of the mounting groove 16. Then, the base end portion 17b of the end locking device was exposed to the flange outer surface through the mounting hole 18, and the base end portion 17b was brought into contact with the flange outer surface and fixed at the fixing portion B by spot welding. In addition,
In the figure, 19 is an insertion hole, and 20 is a regulating portion.

[0026]

According to the reel of the present invention, the end of the metal wire can be easily and quickly locked to the end locking member. Accordingly, work efficiency is remarkably improved, and this is particularly effective when a large number of reels are locked and unwired simultaneously. In addition, since the restricting portion provided on the end locking member serves as a stopper, there is no possibility that the end portion of the metal wire body will bite into the end locking member, and the end locking member may be damaged due to a work error. Disappears. Therefore, the life of the reel can be extended. Furthermore, if the tip of the end locking member is slightly bent outward along the outer peripheral edge of the flange, the metal wire body may be rubbed or caught by the end locking member during winding or unwinding. Not
