Description

[Detailed description of the device]

[0001]

[Industrial applications]

 In order to continuously supply metal wires to a binding machine or the like that uses metal wires to bind the intersections of reinforcing bars or the like, a long metal wire can be wound and housed and a holding portion of the binding machine or the like can be provided. The present invention relates to a metal wire reel that is detachably configured.

[0002]

[Prior art]

 For example, Japanese Patent Publication No. 3-60989 discloses a reinforcing bar binding tool for binding a crossing of reinforcing bars arranged at a construction site of a reinforced concrete structure with a metal wire. In this type of binding tool, a metal wire reel containing a long metal wire wound therein is rotatably mounted on, for example, a holding portion formed at the rear end of the reinforcing bar binding tool to continuously connect the metal wire to the binding machine. I supply it. This type of binding tool is made lightweight to improve workability, and it is not possible to install a large reel around which a large amount of metal wire is wound on the tool. Therefore, it is necessary to mount a relatively small reel around which a metal wire of a predetermined length is wound on the tool, and replace the reel when the reel metal wire is used up.

Generally, a reel is spring-biased from one holding portion side to the other holding portion side so that the reel is rotatably supported between a pair of holding portions protruding from the tool. And is configured to be supported by the other fixed bearing. On the other hand, a reel containing a metal wire or the like wound around it is provided with a reinforcement that is radially and circumferentially connected to the outer surface of the flange in order to prevent the flange from being deformed by pressure when the wire is wound. Ribs are formed, and the reinforcing ribs, in particular, the reinforcing ribs extending in the circumferential direction and the shaft rods biased by the spring are engaged with each other to prevent the reel from being mounted or removed. For this reason, a knob for retracting and operating the shaft rod is integrally formed at the outer end of the shaft rod, and the operator operates the knob against the spring force to completely move the reel to the tool holding portion. It required a great deal of annoyance that it had to be inserted.

[0004]

[Problems to be solved by the device]

 The present invention solves the above-mentioned problems of the prior art and provides a reel for a metal wire which can be mounted by simply pushing the reel between the holding portions of the tool and can be easily removed from the reel. The challenge is to provide.

[0005]

[Means for Solving the Problems]

 A cylindrical winding drum formed of a synthetic resin and having boss portions formed with shaft holes at both ends, and a disc formed with reinforcing ribs formed on both ends of the winding drum and extending at least in the circumferential direction on the outer surface. A reel for a metal wire comprising a flange portion, wherein a gentle inclined surface is formed between the boss portion and the outer surface of the collar portion, and a part of the outer surface of the collar portion is formed from the outer peripheral edge of the collar portion. The lack of a circumferential reinforcing rib that hangs in the radial direction toward the boss is formed, and an inclined surface is formed between the outer surface of the flange and the circumferentially extending reinforcing rib. It is a feature.

[0006]

[Action]

 The outer part of the outer surface of the collar of the reel is formed with a lack of circumferential reinforcing ribs, and an inclined surface is formed between the outer surface of the flange and the boss. The shaft rod provided in the shaft portion is automatically retracted by the mounting operation of the reel and is engaged with the shaft hole formed in the boss portion. Even when the shaft rod comes into contact with the outer surface of the inner rib of the reinforcing rib in the circumferential direction by spring force even when the reel is removed, it is formed between the reinforcement rib and the outer surface of the rib by the reel take-out operation. The inclined surface forcibly retracts the rod, allowing the reel to be taken out.

[0007]

[Effect of device]

 When mounting the reel, it is not necessary to retract the shaft rod, and the mounting is completed simply by pushing the reel with the reinforcing rib lacking part facing the shaft rod. In addition, at the time of disengagement, it is only necessary to first retract the shaft rod to disengage it from the shaft hole, and then to remove the reel from the support part, so that the shaft rod and the reinforcing rib can be prevented from getting caught. Therefore, the operation of mounting and withdrawing the reel from the tool is easy and the workability can be improved.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. 1, 2 and 3 show the entire reel 1 for metal wire of the present invention, which is a cylindrical winding drum portion 2 and a disk-shaped collar portion integrally formed at both ends of the winding drum portion 2. It is composed of 3 and 3. Shaft holes 4 and 4'for rotatably supporting a tool such as a reinforcing bar binding machine by a holding portion are formed on the end surfaces of boss portions formed on both end surfaces 2'of the winding barrel portion 2. Further, a drive hole 5 for rotating the reel when winding the metal wire around the reel is formed on one end surface.

Reinforcing ribs 6 and 6 extending substantially radially from the shaft hole 4 and reinforcing ribs 7 formed along the outer peripheral edge of the collar portion 3 are formed on the outer surface of the collar portion 3 on the outer diameter side end of the reinforcing rib 6. And the reinforcing ribs 7 are formed so that the ends thereof are continuous. As shown in FIG. 2, the reinforcing rib 7 formed along the outer peripheral edge of the collar portion 3 has a notch portion 7 ′ that is lacking at a part of the circumference and is arranged substantially in parallel. The outer surface of the collar portion 3 in this portion sandwiched between the reinforcing ribs 6 and 6 extends from the outer peripheral edge to the outer end of the winding drum portion 2 at a surface of the same height. In this embodiment, the absent portions 7'are provided in four radial positions centering on the shaft hole 4, but the objective can be achieved if they are formed in at least one spot.

The outer end surface 2 ′ of the winding barrel portion 2 is formed by bulging slightly outward from the outer surface of the collar portion 3, and the outer end surface 2 ′ and the outer surface of the collar portion 3 are loose. It is formed continuously by the inclined surface 8. Further, on the inner peripheral side of the reinforcing rib 7 formed along the outer peripheral edge of the collar portion 3, a gentle inclined surface 9 is formed between the outer surface of the collar portion 3 and the top surface of the reinforcing rib 7 and the collar. The outer surface of the portion 3 is continuous by the inclined surface 9. In the embodiment shown in the drawing, the lacking portion 7 ′ of the reinforcing ribs in the circumferential direction and the inclined surface 8 and the inclined surface 9 are formed only on the outer surface of one of the collar portions 3, but both of the collar portions 3 are formed. It may be formed on the outer surface.

Next, a state in which the reel 1 of the present invention is mounted on the tool 13 such as a reinforcing bar binding machine will be described with reference to FIGS. 5 and 6. Arms 14 and 14 are formed on the tool 13 as reel holding portions so as to face each other. The arms 14 and 14 ′ are rotatably supported at the tips of the arms 14 and 14, respectively. Bearings 15 and 16 are provided. One bearing 15 is formed integrally with the arm 14, but the other bearing 16 is a shaft rod 17 which is spring-biased in the direction of the one bearing 15 and a knob 18 for retracting the shaft rod 17. It is configured.

When the flange portion 3 ′ of the reinforcing rib in the circumferential direction of the reel 1 is made to correspond to the bearing 16 and the flange portions 3 are inserted between the bearings 15 and 16, the shaft rod 17 causes the flange portion 3 of the flange portion 3 to move. It comes in contact with the side surface and is slightly retracted to retreat. When the reel 1 is further pushed in this state, the shaft rod 17 engages with the inclined surface 8 and is further retracted so that the shaft rod 17 and the shaft hole 4 are engaged. At this time, at the same time, the bearing 15 and the shaft hole 4'engage with each other so that the reel 1 is supported by the tool.

When the reel 1 is detached from the support portion of the tool, the knob 18 connected to the shaft rod 17 is pulled to retract the shaft rod 17 against the spring force, and the shaft rod 16 and the shaft hole 4 rod are engaged. And the engagement between the bearing 15 and the shaft hole 4'is disengaged, and the reel 1 is moved in an arbitrary direction from between the bearings 15 and 16. Even if the knob 18 is released after this movement, the shaft rod 17 engages with the outer surface of the collar portion 3 by a spring biasing force. For example, even if the shaft rod 17 is inside the reinforcing rib on the outer peripheral side, The inclined surface 9 formed on the inner side of the outer peripheral reinforcing rib 7 by pulling out 1 allows the shaft rod 17 to easily get over the outer peripheral reinforcing rib 7.

As shown in FIGS. 1, 3 and 4, one of the flanges 3 has a radial slit 10 extending from the outer peripheral edge of the flange 3 toward the shaft hole 4 to the outer peripheral surface of the winding drum 2. The circumferential slit 11 is formed continuously from the inner diameter side end of the radial slit 10 along the outer peripheral surface of the winding drum 2. The width of the radial slit 10 is equal to or slightly wider than the diameter of the metal wire wound around the reel 1, and the width of the circumferential slit 11 is smaller than the diameter of the metal wire. . Further, at the end of the circumferential slit 11, a through hole 12 having a diameter slightly larger than the diameter of the metal wire is formed so as to be continuous with the circumferential slit 11.

When the metal wire is wound on the reel, the winding start end (use end) of the wire is inserted from the outer peripheral side of the radial slit 10 to advance in the radial slit 10 in the inner diameter direction of the collar portion 3. Then, it is further moved in the circumferential direction of the winding drum along the circumferential slit 11 and moved to the through hole 12. At this time, since the width of the circumferential slit 11 is set smaller than the diameter of the metal wire, the resistance increases, but since the material forming the reel 1 is synthetic resin, the circumferential slit 11 is deformed due to the deformation of the material. Can be passed. After moving to the through hole 12, the end portion of the metal wire is appropriately bent along the outer surface of the collar portion 3, and then the long metal wire is wound around the outer circumference of the winding drum 2 of the reel 1. Let it house.
