As a result, the wire locking body exposed portion 93 passes through the cut portion 6A and passes the wire W sent between the center hook 70C and the first side hook 70R, and between the center hook 70C and the first side hook 70R. The wire W fed to the curl forming section 5A, the wire W that is curled in the curl forming section 5A and fed between the center hook 70C and the second side hook 70L, and the center hook 70C and the second side hook. 70L and through which the wire W abutted against the feed restricting portion 90 passes.

<Example of operation of bundling equipment according to the present embodiment>
7A and 7B are operation explanatory diagrams showing an example of the operation of binding the reinforcing bars with the reinforcing bar binding machine in the binding facility. The operation of bundling with the wire W will be described.

The tying equipment 100A moves the reinforcing bars S so that the intersecting portion of the reinforcing bars S to be bound faces the curl forming section 5A of the reinforcing bar binding machine 1A, and the curl guide 50 and the guiding guide 51 of the curl forming section 5A are moved. The reinforcing bar binding machine 1A is moved so that the binding target portion of the reinforcing bar S is included between the

The reinforcing bar binding machine 1A drives a feed motor (not shown) in the forward rotation direction, and feeds the wire W in the forward direction indicated by the arrow F by the wire feeding section 3A. In the wire feeding section 3A, two wires W are fed in parallel along the axial direction of the loop Ru formed by the wires W. As shown in FIG.

The wire W sent in the forward direction passes between the center hook 70C and the first side hook 70R and is sent to the curl guide 50 of the curl forming section 5A. As the wire W passes through the curl guide 50, the wire W is curled around the reinforcing bar S by the guide members 53a and 53b.

The wire W that has been curled by the curl guide 50 is guided to the guiding guide 51, and further fed in the forward direction by the wire feeding section 3A, so that the guiding guide 51 guides the wire W between the center hook 70C and the second side hook 70L. is induced to Then, the wire W is fed until its tip abuts against the feed restricting portion 90 . By restricting the feeding path of the wire W fed by the wire feeding section 3A by the curl forming section 5A, the trajectory of the wire W forms a loop Ru as indicated by the dashed line in FIG. is turned. When the tip of the wire W is fed to a position where it abuts against the feed restricting portion 90, the driving of the feed motor (not shown) is stopped.

After stopping the feeding of the wire W in the forward direction, the motor 80 is driven in the forward rotation direction. In the motion range where the rotation restricting portion 74 restricts the rotation of the sleeve 71 interlocked with the rotation of the rotating shaft 72, the rotating motion of the rotating shaft 72 is converted into linear movement, and the sleeve 71 moves upward in the arrow A1 direction. Moving.

When the sleeve 71 moves upward, the opening/closing pin 71 a passes through the opening/closing guide hole 73 . As a result, as shown in FIG. 6B, the first side hook 70R rotates about the shaft 71b and moves toward the center hook 70C. When the first side hook 70R is closed with respect to the center hook 70C, the wire W sandwiched between the first side hook 70R and the center hook 70C is pulled between the first side hook 70R and the center hook 70C. is locked in such a way that it can move.

In addition, the second side hook 70L moves toward the center hook 70C by rotating with the shaft 71b as a fulcrum. When the second side hook 70L is closed with respect to the center hook 70C, the wire W sandwiched between the second side hook 70L and the center hook 70C is pulled between the second side hook 70L and the center hook 70C. It is locked in such a way that it does not come off.

After the sleeve 71 is moved to the end position of the motion range where the wire W is locked by the closing motion of the first side hook 70R and the second side hook 70L, the rotation of the motor 80 is temporarily stopped, and the feed motor (not shown) is moved. in the opposite direction of rotation. As a result, the pair of feed gears 30 are reversed. Therefore, the wire W sandwiched between the pair of feed gears 30 is fed in the opposite direction indicated by the arrow R.

The wire W wound around the reinforcing bar S and locked by the wire locking body 70 has a portion on the tip side sandwiched between the second side hook 70L and the center hook 70C, which is the second side hook. It is locked in such a manner that it cannot be pulled out from between 70L and center hook 70C. In addition, the wire W locked by the wire locking body 70 has a portion that is sandwiched between the first side hook 70R and the center hook 70C. It is locked in such a manner that it can move in the circumferential direction of the loop Ru along the feed path of W.

As a result, the wire W wound around the reinforcing bar S is wound around the reinforcing bar S by sending the wire W in the opposite direction indicated by the arrow R, as shown in FIG. 7B. The wire W is not fed in the reverse direction by the wire feeding mechanism 2A by the operation of feeding the wire W in the reverse direction by the reinforcing bar binding machine 1A. Therefore, the wire W is loosened between the reinforcing bar binding machine 1A and the second wire guiding section 24 by the operation of feeding the wire W in the opposite direction by the reinforcing bar binding machine 1A.

When the wire W is pulled back to the position where the wire W is wound around the reinforcing bar S, the drive of the feed motor (not shown) in the reverse rotation direction is stopped. move in the direction The motion of moving the sleeve 71 upward is transmitted to the cutting portion 6A, whereby the movable blade portion 61 rotates, and the wire W locked by the first side hook 70R and the center hook 70C moves to the fixed blade portion. 60 and the movable blade portion 61 are cut.

When the wire W is cut, the bent portions 71c1 and 71c2 move toward the reinforcing bar S. As shown in FIG. As a result, the tip side of the wire W locked by the center hook 70C and the second side hook 70L is pressed toward the reinforcing bar S by the bending portion 71c1, and bent toward the reinforcing bar S using the locking position as a fulcrum. As the sleeve 71 moves further upward, the wire W locked between the second side hook 70L and the center hook 70C is held in a state of being sandwiched between the bent portions 71c1.

Further, the end side of the wire W, which is locked by the center hook 70C and the first side hook 70R and cut by the cutting portion 6A, is pressed toward the reinforcing bar S by the bending portion 71c2, and the reinforcing bar is bent using the locking position as a fulcrum. Bend to the S side. As the sleeve 71 moves further upward, the wire W locked between the first side hook 70R and the center hook is held in a state of being sandwiched between the bent portions 71c2.

After the tip side and the terminal side of the wire W are bent toward the reinforcing bar S, the motor 80 is further driven in the forward rotation direction to move the sleeve 71 further upward. When the sleeve 71 moves to a predetermined position and reaches a motion range in which the wire W locked by the wire locking body 70 is twisted, the rotation restriction of the sleeve 71 by the rotation restriction portion 74 is released, and the rotation axis The sleeve 71 rotates in conjunction with the rotation of 72 .

As a result, the motor 80 is further driven in the forward rotation direction, and the wire locking body 70 rotates in conjunction with the rotating shaft 72 to twist the wire W and bind the reinforcing bar S with the wire W. When it is detected that the load applied to the motor 80 reaches a predetermined value, for example, the maximum load, the forward rotation of the motor 80 is stopped at a predetermined timing.

By rotating the motor 80 in the reverse direction after stopping the forward rotation of the motor 80, the first side hook 70R opens with respect to the center hook 70C, and the second side hook 70L opens with respect to the center hook 70C. The sleeve 71 is moved downward to the open position, and the wire bundle 70 is returned to the standby position. When the wire W that binds the reinforcing bars S is separated from the wire binding body 70, the reinforcing bar binding machine 1A is moved to the standby position.

The wire feeding mechanism 2A feeds the wire W in the reverse direction and winds it around the reinforcing bar S in the binding operation of the reinforcing bar binding machine 1A described above, and then feeds the wire W in the forward direction in the next binding operation. An operation of pulling out a predetermined amount of wire W from the reel 20 is performed.

The wire feed mechanism 2A rotates the motor 22c forward to lower the drawing roller 22a from the upper limit position P1. The wire drawing mechanism 22 is arranged such that the drawing roller 22a is positioned at the upper limit position P1 along the direction intersecting the wire W between the roller 23a of the first wire guide portion 23 and the roller 24a of the second wire guide portion 24. to the lower limit position P2.

When the pull-out roller 22a starts to descend from the upper limit position P1, the wire W between the roller 23a of the first wire guide portion 23 and the roller 24a of the second wire guide portion 24 is pulled downward, so that the reel 20 and the wire W between the first wire guide portion 23 and the wire W between the reinforcing bar binding machine 1A and the second wire guide portion 24 are connected to the first wire guide portion 23 and the second wire guide portion 24. Therefore, the wire W between the reinforcing bar binding machine 1A and the second wire guide portion 24 and the wire W between the first wire guide portion 23 and the reel 20 housed in the reel housing portion 21 The wire is fed between the roller 23 a of the second wire guiding portion 23 and the roller 24 a of the second wire guiding portion 24 .

As described above, the load applied to the wire W guided by the first wire guide portion 23 is greater than the load applied to the wire W guided by the second wire guide portion 24, and the first load > the second load. configured to be a load.

Further, in the reinforcing bar binding machine 1A, the wire W is wound around the reinforcing bar S by feeding the wire W in the opposite direction in the operation of binding the reinforcing bar S with the wire W. The wire W is not fed in the reverse direction by the wire feeding mechanism 2A by the operation of feeding the wire W in the reverse direction by the reinforcing bar binding machine 1A. Therefore, the wire W is loosened between the reinforcing bar binding machine 1A and the second wire guiding section 24 by the operation of feeding the wire W in the opposite direction by the reinforcing bar binding machine 1A.

As a result, in the operation of pulling the wire W by the pull-out roller 22a of the wire pull-out mechanism 22, the surplus wire W loosened in the wire W feeding path 26 between the reinforcing bar binding machine 1A and the second wire guide section 24 is first pulled. The wire is drawn between the roller 23 a of the first wire guide 23 and the roller 24 a of the second wire guide 24 .

When the surplus of the wire W between the reinforcing bar binding machine 1A and the second wire guide section 24 is fed and the slack in the wire W is eliminated, the pair of feed gears 30 of the wire feeding section 3A are stopped and do not rotate. As a result, the wire W cannot be fed in the wire W feeding path 26 between the reinforcing bar binding machine 1A and the second wire guiding section 24. FIG. As a result, the feed gear 30 acts as a load to increase the tension applied to the wire W between the reinforcing bar binding machine 1A and the second wire guide portion 24, and the load from the feed gear 30 is added to the second load, Second load+feed gear load>first load.

When the second load+the load of the feed gear>the first load, the wire W is pulled out from the reel 20 accommodated in the reel accommodation portion 21, and the roller 23a of the first wire guide portion 23 and the second wire guide It is sent between the rollers 24a of the section 24 and the rollers 24a. When the pull-out roller 22a moves to the lower limit position, the slackness of the wire W in the feeding path 26 of the wire W between the reinforcing bar binding machine 1A and the second wire guiding part 24 is eliminated, and the reinforcing bar S is pulled by the reinforcing bar binding machine 1. The amount of movement of the pull-out roller 22a is set so that the amount of wire W required for binding can be pulled out from the reel 20. As shown in FIG.

When the pull-out roller 22a descends to the lower limit position P2, the wire feed mechanism 2A switches the rotation direction of the motor 22c from forward rotation to reverse rotation to raise the pull-out roller 22a. When the pull-out roller 22a reaches the upper limit position P1, the rotating direction of the motor 22c is stopped. As a result, between the roller 23a of the first wire guide section 23 and the roller 24a of the second wire guide section 24, the amount of wire W necessary for binding the reinforcing bar S with the reinforcing bar binding machine 1A is loosened. state.

In the next binding operation performed by the reinforcing bar binding machine 1A, the wire feed unit 3A feeds the wire W in the forward direction so that the roller 23a of the first wire guide unit 23 and the roller 24a of the second wire guide unit 24 The wire W slackened between and is fed toward the reinforcing bar binding machine 1A.

In this way, depending on the magnitude of the load applied to the wire W guided by the first wire guide portion 23 and the load applied to the wire W guided by the second wire guide portion 24, the first wire guide portion 23 side , or the wire W on the second wire guiding portion 24 side is switched.

As a result, in order to wind the wire W around the reinforcing bar S, the wire W is fed in the opposite direction by the reinforcing bar binding machine 1A, and the wire W feeding path 26 between the reinforcing bar binding machine 1A and the second wire guide section 24 The generated slackness of the wire W can be eliminated by the operation of drawing out the wire W by the wire drawing mechanism 22 . In addition, the amount of wire W required for binding the reinforcing bars S by the reinforcing bar binding machine 1A can be pulled out from the reel 20 by pulling out the wire W with the wire pulling mechanism 22 .

As described above, in the binding facility 100A, the reinforcing bar binding machine 1A is configured so that the curl forming portion 5A faces upward, and the opening 82 of the wire locking body exposed portion 93 faces upward. For this reason, in the binding equipment 100A, when the reinforcing bar S is put into the curl forming part 5A of the reinforcing bar binding machine 1A and the reinforcing bar S is hit against the abutting part 91, the reinforcing bar S and the abutting part 91 rub against each other. There is a possibility that foreign matter adhering to the reinforcing bar S may drop and enter the wire locking member exposed portion 93 through the opening 92 .

Further, when the wire W passes between the center hook 70C and the first side hook 70R, and between the center hook 70C and the second side hook 70L, the wire W is attached to the wire locking body. Foreign matter such as shavings generated by rubbing with 70 falls on the bottom surface forming wall portion 93 a inside wire locking body exposed portion 93 . Furthermore, there is a possibility that the cut end of the wire W may drop to the bottom surface forming the wall portion 93a inside the wire locking body exposed portion 93 due to the operation of cutting the wire W at the cutting portion 6A.

Therefore, the reinforcing bar binding machine 1A includes a discharging section 94 for discharging the foreign matter in the wire locking body exposed section 93 to the outside of the main body section 10A. The discharge part 94 is configured by providing openings communicating with the wire locking body exposed part 93 on both sides of the main body part 10A.

Further, the discharge portion 94 is provided with a discharge guide portion 94a which is flush with the bottom surface of the wall portion 93a constituting the wire locking body exposed portion 93, so that the sides of the discharge portion 94 and the bottom surface of the wire locking body 93 are aligned. In this configuration, there is no convex portion that hinders the discharge of foreign matter.

As a result, foreign matter in the wire locking body exposed portion 93 can be discharged from the discharge portion 94 to the outside of the main body portion 10A. In addition, by providing the discharge portion 94 with the discharge guide portion 94a, it is possible to prevent foreign matter from accumulating in the side portions of the opening that constitutes the discharge portion 94 .

Further, the discharge guiding portion 94a is formed not only on the bottom surface of the wall portion 93a constituting the wire locking body exposing portion 93, but also on the wall portions 93a other than the bottom surface. are connected on the same plane, it is possible to prevent foreign substances from accumulating in the portions on each side of the opening that constitutes the discharge portion 94 .

In the reinforcing bar binding machine 1A, in the operation of binding the reinforcing bars S described above, the wires W wound around the reinforcing bars S are twisted by rotating the wire locking body 70, and the wires W are cut off carelessly. Sometimes. A wire W cut carelessly is called a wire piece. The wire piece has a length of about 10 mm to 15 mm. The wire piece cut by the operation of rotating the wire locking body 70 is inserted into the wire locking body exposed portion 93 by opening the first side hook 70R and the second side hook 70L with respect to the center hook 70. It may fall.

Therefore, the width of the opening of the discharge portion 94 is made larger than the radial dimension of the wire locking body 70 . Specifically, when the length of the wire piece is LW, the openings forming the discharge portion 94 are arranged along one direction and another direction orthogonal to the one direction, as shown in FIGS. 3D and 3E. The length is LW, in this example, a shape that has a portion that is equal to or greater than the diameter of the virtual circle C1 having a diameter of 10 mm or more in at least a part between the opposing sides, and the diameter of the virtual circle C1 having a diameter of 10 mm A shape that includes a portion in any two directions.

For example, the opening constituting the discharge portion 94 has a length L1 in the direction along the axial direction of the rotating shaft 72 and a length L2 in the direction perpendicular to the axial direction of the rotating shaft 72, which is equal to or greater than the length LW of the wire piece. That is, it is preferable that they are 10 mm or more and 50 mm or less, respectively. From the relationship between the dischargeability of the wire pieces and the configuration of the reinforcing bar binding machine 1A, it is more preferable that each of the above dimensions is 13 mm or more and 15 mm or less. It should be noted that the opening forming the discharge portion 94 does not have to be substantially rectangular as shown in FIG. Even in this case, the length L1 of the rotating shaft 72 in the direction along the axial direction and the length L2 of the rotating shaft 72 in the direction orthogonal to the axial direction are each the length LW of the wire piece or more, and in this example, 10 mm or more. , the wire piece can be discharged from the discharge portion 94 regardless of the direction of the wire piece. Thereby, the discharge portion 94 can be configured with an opening having a necessary and sufficient area for discharging the foreign matter.

Note that the reinforcing bar binding machine 1A vibrates when the reinforcing bars S are moved in and out of the curl forming section 5A, when the reinforcing bars S are tied, and the like. Vibration of the reinforcing bar binding machine 1A promotes the discharge of foreign matter in the wire locking body exposed portion 93 from the discharge portion 94 to the outside.

Therefore, a mode for discharging the foreign matter is set as the discharging means, and the reinforcing bar binding machine 1A is vibrated by elevating the reinforcing bar binding machine 1A by the elevating mechanism 111A or the like at a predetermined timing when the binding operation is not executed, and the wire is It is also possible to promote the discharge of foreign matter in the locking body exposed portion 93 to the outside from the discharge portion 94 .

As another discharging means, a foreign matter discharging mode is set, and the bottom surface of the wall portion 93a constituting the wire locking body exposed portion 93 is inclined in a direction downward from the hole portion 93b toward the discharging portion 94. In this way, the foreign matter in the wire locking body exposed portion 93 may be promoted to be discharged from the discharge portion 94 to the outside.

Further, the reinforcing bar binding machine 1A is provided with a discharge section 31 for discharging foreign substances in the wire feeding section 3A in the body section 10A to the outside of the body section 10A. In the wire feeding section 3A, the wire W is sandwiched between a pair of feeding gears 30, and foreign matter such as shavings generated by the wire W rubbing against the feeding gear 30 is removed by the wire feeding section 3A. Fall into the space you enter. Therefore, by configuring the discharge portion 31 with an opening that communicates with the space in which the feed gear 30 and the like enter, foreign matter in the wire feed portion 3A can be discharged from the discharge portion 31 to the outside of the main body portion 10A.
