- a motor 51 that rotates the second rotating shaft 49 is provided in the axial center of the second rotating shaft 49.
- the motor 51 is an example of a first drive unit.
- the motor 51 is provided to correspond to each of the pair of link members 42A, 42B.
- the second link 43 has a bearing portion that is approximately U-shaped, and the bearing portion supports the wheel 17 so that it can rotate freely.
- the wheel 17 has a disk-shaped flange portion 17A on both sides in the width direction to prevent it from falling off the vertical bars X2, X3.

- the reinforcing bar binding device 10 is provided with a motor 52 that corresponds individually to each of the four wheels 17, making it possible to control the rotation of each wheel 17 individually.
- the motor 52 may be built into each wheel 17.
- the second link 43 rotates relative to the first link 42 around the second rotating shaft 49 in conjunction with the rotation of the second rotating shaft 49.
- the second link 43 rotates in the clockwise direction shown in FIG. 8 around the second rotating shaft 49, and the second link 43 rotates relative to the first link 42 so that the angle at which the first link 42 and the second link 43 intersect increases.
- the displacement mechanism 41 is configured to be displaceable with the first end connected to the base 40 as a fixed end and the second end opposite the first end as a free end, so that the second rotating shaft 49 moves in the X-axis direction toward the base 40.
- the displacement direction of the wheel 17 provided at the tip of the displacement mechanism 41 is restricted by the restricting link mechanism 45. Therefore, when the motor 51 is driven, the wheel 17 at the tip of the displacement mechanism 41 rises or falls in the vertical direction.
- the main body 11 has a through-hole 60 that penetrates the main body 11 in the Z-axis direction.
- the through-hole 60 opens on the top surface of the main body 11, and the binding mechanism 70 is inserted from above.

- the holding section 71 is provided in the center of the longitudinal direction of the binding mechanism 70.
- the holding section 71 holds a roll of metal wire wound around it.
- the binding section 73 has a configuration in which two arms 73A, 73B cross in a roughly V-shape, and with the opposing directions of the two arms 73A, 73B aligned in a direction that crosses the binding site diagonally, the wire unwound from the holding section 71 is wound between one arm 73A and the other arm 73B to perform the binding process on the binding site using the wire.
- the bundling unit 73 performs bundling processing on the bundling area using wire by winding the wire around the bundling area, winding the wire wound around the bundling area so that it is tightly attached to the bundling area, and twisting the wire wound around the bundling area.
- the binding mechanism 70 has a disk-shaped engagement portion 74.
- the planar shape of the engagement portion 74 is larger than the opening shape of the through-hole 60. Therefore, when the binding mechanism 70 is inserted into the through-hole 60, the engagement portion 74 engages with the opening edge of the through-hole 60 in the Z-axis direction to position the binding mechanism 70.
- the binding mechanism 70 has a binding portion 73 provided on one side in the longitudinal direction based on the engagement portion 74 (in this example, the lower side).
- the binding mechanism 70 includes a lifting unit 72 that raises and lowers the binding part 73 in the Z-axis direction.
- the lifting unit 72 raises and lowers the binding part 73 in the Z-axis direction, so that the binding part 73 is accurately lowered to the binding location, and the binding process using the wire is performed accurately on the binding location.
- the binding portion 73 of the binding mechanism 70 protrudes downward from the underside of the main body 11.
- the rebar binding device 10 then runs following the vertical bar X1.
- the binding portion 73 of the binding mechanism 70 is positioned above and spaced apart from the vertical bar X1.
- the two arm portions 73A, 73B of the binding portion 73 face each other in a direction that intersects obliquely with the longitudinal direction of the vertical bar X1.
- the rebar binding device 10 travels following the vertical bar X1, and when the rebar binding device 10 reaches a position facing the horizontal bar in the Z-axis direction, the binding part 73 of the binding mechanism 70 is lowered to a position where the distance from the vertical or horizontal bar is a predetermined distance with the extension and contraction of each leg 15 of the main body 11, and the binding part 73 of the binding mechanism 70 is aligned with the binding part in the Z-axis direction.
- the two arms 73A and 73B of the binding part 73 face each other in a direction that crosses the binding part diagonally.
- the binding part 73 wraps the wire from one arm 73A to the other arm 73B, thereby performing the binding process of the binding part using the wire.
- the binding mechanism 70 When inserted into the through-hole 60, the binding mechanism 70 is configured to be rotatable in the circumferential direction about a rotation axis passing through the center of the opening of the through-hole 60. In this case, the binding mechanism 70 may be rotated manually or may be rotated based on a driving force from a motor, which is an example of a rotation drive unit. When the binding mechanism 70 rotates in the circumferential direction about the rotation axis, the orientation of the two arm portions 73A, 73B of the binding portion 73 is changed. Therefore, the binding mechanism 70 can use the wire to perform the binding process on the binding portion not only when the vertical and horizontal bars intersect at right angles, but also when the vertical and horizontal bars intersect diagonally.

- the main body 11 approaches the vertical bar X4 that is adjacent in the Y-axis direction to the vertical bar X3 on which the leg 15 is placed.
- the reinforcing bar binding device 10 contracts each leg 15 constituting the leg structure 12, lowering the height of the main body 11 relative to the vertical bars X1 and X3. Then, the reinforcing bar binding device 10 abuts the support frame 13 connected to the main body 11 against the vertical bars X1 and X3. In this case, the support frame 13 is placed so as to straddle two vertical bars X1 and X3, including the vertical bar X1 along which the reinforcing bar binding device 10 runs and the vertical bar X3 adjacent to the vertical bar X1 in the Y-axis direction.

- each leg 15 constituting the leg structure 12 is positioned to face the vertical bars X1 and X4 in the Z-axis direction.
- the rebar binding device 10 extends each leg 15 constituting the leg structure 12, and abuts each leg 15 against the vertical bars X1, X4 (corresponding to the third process). Then, when the rebar binding device 10 further extends each leg 15 constituting the leg structure 12 from the state in which each leg 15 abuts against the vertical bars X1, X4, the support frame 13 connected to the main body 11 moves upward away from the vertical bars X3, X4.
- the rebar binding device 10 drives the lateral movement rollers 33 in the forward direction, and moves the main body 11 in the Y-axis direction relative to the leg structure 12 while supporting the leg structure 12 by bringing each leg 15 constituting the leg structure 12 into contact with the vertical bars X1 and X4 (corresponding to the fourth process). This returns the relative positions of the main body 11 and the leg structure 12 in the Y-axis direction to their initial states.
- the reinforcing bar binding device 10 of this embodiment repeats a process of moving the leg structure 12 in the Y-axis direction relative to the main body 11 while the support frame 13 is abutting against the vertical bars X1, X3 or the vertical bars X3, X4 to support the main body 11, and a process of moving the main body 11 in the Y-axis direction relative to the leg structure 12 while the leg structure 12 is abutting against the vertical bars X2, X3 or the vertical bars X1, X4 to support the leg structure 12.
- the reinforcing bar binding device 10 can move in the Y-axis direction efficiently by moving in stages in the Y-axis direction.
- the reinforcing bar binding device 10 can lighten the weight of the object moved in one movement and reduce the driving load of the lateral movement rollers 33 by moving in stages in the Y-axis direction.
- the rebar binding device 10 by moving the rebar binding device 10 in the Y-axis direction in stages, the generation of rotational moment with the legs 15 supported by the vertical bars X2 and X3 or the vertical bars X1 and X4 as fulcrums is suppressed compared to when the movement in the Y-axis direction is performed all at once, and the lateral movement process can be performed stably.
- each leg 15 constituting the leg structure 12 has a restricting link mechanism 45 that restricts the movement direction of the wheel 17. Therefore, the wheel 17 can be stably moved in a direction approaching or moving away from the vertical bars X2, X3 or the vertical bars X1, X4. Therefore, the reinforcing bar binding device 10 is prevented from accidentally colliding with the vertical bars X2, X3 or the vertical bars X1, X4 when the wheel 17 moves in the Y-axis direction away from the vertical bars X2, X3 or the vertical bars X1, X4, and the lateral movement process of the reinforcing bar binding device 10 can be stably performed.
- the reinforcing bar binding device 10 when performing the lateral movement process, if the reinforcing bar binding device 10 detects that the wheel 17 has collided with the vertical bars X2, X3 or the vertical bars X1, X4 based on the motor load of the motor driving the lateral movement rollers 33, it further drives the lateral movement rollers 33 in the direction to move the wheel 17 away from the vertical bars X2, X3 in the Y-axis direction. This allows the reinforcing bar binding device 10 to perform the lateral movement process even more stably.
- the leg 15 that is located in front of the reinforcing bar binding device 10 among the multiple legs 15 that make up the leg structure 12 drives the motor 51 that controls the extension and contraction movement of each leg 15 so that the connection part between the first link 42 located at the first end and the second link 43 located at the second end is positioned in front of the reinforcing bar binding device 10 in the displacement mechanism 41.
- the reinforcing bar binding device 10 judges whether the reinforcing bar binding device 10 has collided with an obstacle based on the change in the load of the motor that moves the reinforcing bar binding device 10 forward. Therefore, the reinforcing bar binding device 10 can judge whether the reinforcing bar binding device 10 has collided with an obstacle when moving forward without providing a new sensor.
- the reinforcing bar binding device 10 drives a motor 51 that controls the extension and contraction movement of the leg 15 so that, when the reinforcing bar binding device 10 accelerates or decelerates forward, the leg 15 that is located in front of the reinforcing bar binding device 10 among the multiple legs 15 that make up the leg structure 12 is positioned such that the connection portion between the first link 42 located at the first end and the second link 43 located at the second end of the multiple links that make up the displacement mechanism 41 is positioned in front of the reinforcing bar binding device 10 in the displacement mechanism 41.
- the reinforcing bar binding device 10 drives a motor 51 that controls the extension and contraction movement of the leg 15 so that, when the reinforcing bar binding device 10 accelerates or decelerates forward, the leg 15 that is located in front of the reinforcing bar binding device 10 among the multiple legs 15 that make up the leg structure 12 is positioned such that the connection portion between the first link 42 located at the first end and the second link 43 located at the second end of the multiple links that make up the displacement mechanism 41 is positioned in front of the reinforcing bar binding device 10 in the displacement mechanism 41. Therefore, when the rebar binding device 10 accelerates or decelerates forward, the height of the main body 11 can be prevented from fluctuating due to the extension and contraction of each leg 15 that constitutes the leg structure 12.
- the coil spring 50 applies a biasing force in a direction that extends the legs 15 and moves the wheels 17 closer to the vertical bars X1, X2, and X3. Therefore, even if the center of gravity of the main body 11 moves up and down as the wire used for binding is consumed as the reinforcing bar binding process progresses, the biasing force from the coil spring 50 acts in response to the movement of the center of gravity of the main body 11, so the main body 11 can maintain the desired position and the reinforcing bars can be bound accurately.
- the rebar binding device 10 applies a biasing force from the coil spring 50 in the direction that extends the legs 15, thereby reducing the power consumption when driving the motor 51 in the direction that extends the legs 15 to support the weight of the main body 11 by the amount of the biasing force of the coil spring 50.
- the power consumption when the rebar binding device 10 performs horizontal control can be further reduced.
- the binding mechanism 70 is inserted into the through-hole 60 provided in the main body 11, and the binding mechanism 70 is configured to be rotatable in the circumferential direction around the center of the opening of the through-hole 60 relative to the main body 11. Therefore, when performing binding processing on a binding portion where vertical and horizontal bars intersect, the reinforcing bar tying device 10 is configured to be able to change the orientation of the two arm portions of the binding portion 73 of the binding mechanism 70. Therefore, the reinforcing bar tying device 10 can use wires to perform binding processing on a binding portion not only when the vertical and horizontal bars intersect at right angles, but also when the vertical and horizontal bars intersect diagonally, and can perform binding processing with high versatility.
- the reinforcing bar binding device 10 performs the lateral movement process when moving to the vertical bar X4 adjacent to the vertical bar X3 on which the leg 15 is supported.
- the reinforcing bar binding device 10 may perform the lateral movement process in other ways. For example, when the reinforcing bar binding device 10 reaches the binding portion, if the position of the binding portion 73 of the binding mechanism 70 does not match the position of the binding portion in the Y-axis direction, the position of the binding mechanism 70 may be fine-tuned in the Y-axis direction in the same manner as the above-mentioned lateral movement process.
- the reinforcing bar binding device 10 may fine-tune the position of the binding mechanism 70 in the Y-axis direction by repeating the process of moving the leg structure 12 in the Y-axis direction relative to the main body 11 with the support frame 13 abutting against the vertical bars X1 and X3 to support the main body 11, and the process of moving the main body 11 in the Y-axis direction relative to the leg structure 12 with the leg structure 12 abutting against the vertical bars X2 and X3 to support the leg structure 12.
