Binding device

1 . A binding device configured to bind an intersection of reinforcing bars arranged in a grid shape with a plurality of wires, the binding device comprising:

a main body part; and

a traveling part configured to travel the main body part along an arrangement surface of the reinforcing bars,

wherein the main body part includes:

one or more binding mechanisms including a pair of feeding gears configured to sandwich and feed the plurality of wires around the reinforcing bars, a hook configured to twist and bind the plurality of wires fed around the reinforcing bars, and a first motor configured to drive the hook,

a binding mechanism moving part including a binding machine bracket to which the binding mechanism is mounted, an actuator configured to move the binding machine bracket, and a second motor configured to drive the actuator, the binding mechanism moving part configured to move the binding mechanism between a binding position where binding of the reinforcing bars is performed and a retreat position away from the reinforcing bars,

a reel holder configured to accommodate a plurality of reels on each of which one wire is wound in an arrangement that the reels are aligned in a left-right direction or an upper and lower direction, when the left-right direction is a direction intersecting a moving direction of the main body part and being along the arrangement surface, and the upper and lower direction is a vertical direction with respect to the arrangement surface, and

a path induction member configured to form a feeding path of wires pulled out from the plurality of reels accommodated in the reel holder between the binding mechanism and the reel holder, and which is attached to the main body part by a support member and provided at the feeding path and which is configured to collect each of the wires pulled out from the plurality of reels in the reel holder and to guide the collected wires to one of the one or more binding mechanisms.

2 . The binding device according to claim 1 , wherein the reel holder is configured to accommodate the plurality of reels in an arrangement that the reels are aligned right and left with respect to a moving direction of the main body part that is moved by the traveling part.

3 . The binding device according to claim 1 , wherein the reel holder is configured to accommodate the plurality of reels in an arrangement that the reels are left-right symmetrical to each other with respect to a moving direction of the main body part that is moved by the traveling part.

4 . The binding device according to claim 1 , wherein the reel holder is configured to accommodate the plurality of reels in an arrangement that the reels are overlapped and rotation axes of the reels are along a vertical direction.

5 . The binding device according to claim 4 , wherein, in the reel holder, the plurality of reels are accommodated in an arrangement that the reels are vertically overlapped.

6 . The binding device according to claim 1 , wherein the binding mechanism includes a binding part configured to twist the wires by a rotating operation, and

wherein the reel holder is configured to accommodate the plurality of reels in an arrangement that the reels are symmetrical to each other with respect to an imaginary line passing through a rotation axis of a rotating operation of the binding part.

7 . The binding device according to claim 6 , wherein, in the reel holder, the plurality of reels are accommodated in an arrangement that the reels are left-right symmetrical to each other with respect to the imaginary line.

8 . The binding device according to claim 6 , wherein an imaginary center line, extending in a traveling direction of the main body part by the traveling part, of the main body part in a left-right direction of the main body part crosses the imaginary line.

9 . The binding device according to claim 1 , wherein the reel holder is configured to accommodate the plurality of reels in an arrangement that the reels are symmetrical to each other with respect to an imaginary line extending from a path induction member closest to the reel holder among a plurality of path induction members.

10 . The binding device according to claim 1 , wherein the reel holder is configured that a difference between a path length of the feeding path of wire from one reel to the binding mechanism and a path length of the feeding path of wire from another reel to the binding mechanism is set shorter than a length of the wire required for the binding mechanism to perform one binding of the reinforcing bar.

11 . The binding device according to claim 1 , wherein the reel holder is configured that a difference between a path length of the feeding path of wire from one reel to the binding mechanism and a path length of the feeding path of wire from another reel to the binding mechanism is set shorter than a circumferential length of a core winding portion on which the wire of the reel is wound.

12 . The binding device according to claim 1 , wherein an imaginary center line, extending in a traveling direction of the main body part by the traveling part, of the main body part in a left-right direction of the main body part does not cross the path induction member.

13 . The binding device according to claim 1 , wherein the binding mechanism includes a binding part configured to twist the wires by a rotating operation, and

wherein the reel holder is configured to accommodate the plurality of reels in an arrangement that the reels are symmetrical to each other with respect to an imaginary line passing through a rotation shaft of the binding part.

14 . The binding device according to claim 1 , wherein the path induction member has an annular shape.
