That is, the measuring means 62 (1) measures the distance L (see FIG. 13A) from the end 125B of the binding assembly 125 to the binding position of the binding wire 127 in the longitudinal direction of the binding assembly 125. And (2) in the circumferential direction of the binding assembly 125, a gap H (see FIG. 14B) formed between the outer surface of the binding object 126 constituting the binding assembly 125 and the binding wire 127. Used for position recognition.

  The measuring means 62 is a non-contact sensor device that does not come into contact with the binding objects 126 and the binding wire 127 of the binding assembly 125, and a laser scanner type non-contact sensor is employed in the embodiment. As shown in FIG. 12, the measuring means 62 includes a laser irradiation unit 100 that irradiates a laser beam, and a measurement object irradiated from the laser irradiation unit 100 (in the embodiment, a binding assembly 125 and a binding wire 127).

A lens 103 or the like for guiding the unit 101 is provided. Such a measuring means 62 is reflected by utilizing the fact that when the distance between the laser irradiation unit 100 and the measurement object is different, the reflection angle of the laser light is different and the light receiving element that receives the reflected laser light is different. The distance is measured by which light receiving element in the light receiving unit 101 receives the laser light.

  Regarding the measurement of the distance L according to the above (1), as shown in FIG. 13A, along the outer circumferential portion 125A from the end 125B side of the binding assembly 125, along the longitudinal direction of the binding assembly 125. By continuously measuring the distance from the laser irradiation unit 100 to the outer peripheral part 125A while moving the measuring means 62, the outer surface shape in the longitudinal direction of the outer peripheral part 125A is acquired. The outer surface shape of the outer peripheral portion 125A of the body 125 is measured. At this time, as shown in FIG. 13B, since the binding wire 127 protrudes outward from the outer peripheral portion 125A of the binding assembly 125, the measured outer shape is as shown in FIG. 13C. It becomes the shape which protruded in the part of the binding wire 127, Thereby, the said distance L from the edge part 125B to the binding wire 127 can be measured. When the distance L is measured, the hook 123 of the identification marker wire 120 gripped by the identification marker wire mounting device 12 is attached to the binding wire 127 of the binding assembly 125 positioned in the set unit 11. When hooked, the control means 14 can recognize the position in the left-right direction (longitudinal direction) where the tip of the second hooking portion 123B of the hooking portion 123 arrives.

The distance from the laser irradiation unit 100 to the outer peripheral part 125A is continuously measured while moving the measuring means 62 along the direction. By measuring the distance in this way, the outer surface shape in the circumferential range of the outer peripheral portion 125A of the binding assembly 125 is acquired, and the outer shape of the outer peripheral portion 125A of the binding assembly 125 by each binding object 126 is measured. Is done. At this time, since the bound objects 126 are arranged in the circumferential direction on the outer peripheral portion 125A of the bound assembly 125, as shown in FIG. The portion of the object 126 is convex, and the portion between the binding objects 126 and 126 adjacent in the circumferential direction is concave.

  Therefore, based on the measured outer shape of the outer peripheral portion 125A of the binding assembly 125, the binding object 126 positioned on the outer periphery of the binding assembly 125 and adjacent in the circumferential direction is interposed between the binding wires 127. The formation position of a certain gap H can be calculated. That is, in the embodiment, as shown in FIG. 14C, in the outer surface shape of the outer peripheral portion 125A measured by the measuring means 62, the first vertex P1 protruding from the outer peripheral portion 125A of the bundle assembly 125, and the first vertex P1 A second vertex P2 protruding from the outer peripheral portion 125A adjacent to the circumferential direction of the bundling assembly 125 is extracted from one vertex P1. Then, a tangent line 106 connecting the binding object 126 in which the first vertex P1 appears and the binding object 126 in which the second vertex P2 appears is calculated, and the outer peripheral portion 125A side of the tangential line 106 is placed on the gap H. It is calculated as a formation position.

  In addition, as shown in FIG.14 (c), when the said binding object 126 is a long round bar, in the said clearance gap H, the binding object 126 and the said 2nd vertex P2 in which the said 1st vertex P1 appears The tangent line 106 that connects the binding object 126 has a substantially triangular shape that has the maximum distance from the binding wire 127 on the extension line of the perpendicular 107 that is perpendicular to the tangent line 106 at the intermediate position between the contact points of the binding objects 126 and 126. There is no. Therefore, in the direction of the perpendicular 107 perpendicular to the tangent line 106 from the intermediate position of the tangent line 106, and at a position separated from the tangential line 106 by a size corresponding to the radius of the second hooking portion 123B or more. It is desirable to set so that the 2nd latching part 123B of the wire 120 is inserted. Accordingly, when the hooking portion 123 of the wire for identification sign 120 held by the wire attaching device for identification mark 120 is hooked with the binding wire 127 of the bundle assembly 125 positioned on the set portion 11, the hooking portion 123 is hooked. The front and rear direction (circumferential direction) and the vertical direction position at which the tip of the second hooking portion 123B in the portion 123 arrives can be accurately recognized by the control means 14.

  Therefore, in the embodiment, the measuring means 62 recognizes the shape of each of the outer peripheral portions 125A in the longitudinal direction and the circumferential direction of the bundling assembly 125, so that the identification marker wire 120 gripped by the identification marker wire mounting device 12 is used. When hooking the binding wire rod 127 of the binding assembly 125 positioned on the set portion 11, the position of the gap H at which the leading end of the second hooking portion 123 </ b> B arrives at the hooking portion 123 is determined.

By displacing and moving the first slide body 75 of the locking means 61 further to the left and moving the second slide body 76 up and down appropriately, the second latching portion is moved relative to the first latching portion 123A. 123B is bent leftward about the bent portion 123C, and the second hooking portion 123B is wound around the binding wire 127. Further, at this time, the first hooking portion 123A of the hooking portion 123 is pulled rightward by appropriately moving the identification mark wire attaching device 12 to the right as a whole. The part 123A and the second hooking part 123B are wound around the binding wire 127 so as to tighten the binding wire 127. Further, when the second hooking portion 123B is bent, as shown in FIG. 16 (b), the identification sign wire attaching device 12 is moved only in the clockwise direction in the plan view with the bending portion 123C as the center. By rotating, the first hooking portion 123A and the second hooking portion 123B are twisted in the horizontal direction, so that no gap is formed between the hooking portions 123A and 123B.

(Wire marking molding process for identification signs)
When the rotated identification sign wire attaching device 12 is returned to the original posture and the identification sign wire holding process is completed, the identification sign wire attaching forming process is executed. In this identification marker wire attaching and forming step, first, as shown in FIG. 17A, the distance L from the end portion 125B of the binding assembly 125 measured by the measuring means 62 to the binding position of the binding wire 127 is set. Based on this, the deformation means 63 is positioned in the left-right direction. That is, the gripping position of the gripping means 60 with respect to the identification marker wire 120 by the gripping portions 70, 70 is constant, but the binding position of the binding member 127 is different for each binding assembly 125. Based on the measured distance L, the restricting mechanism 71 is set as a restricting position, and the gripping portions 70 and 70 are changed to the semi-holding positions so that the position for gripping the identification marker wire 120 can be changed. The position where the gripping portions 70, 70 of the gripping means 60 are gripped with respect to the marker wire 120 is adjusted so that the deforming means 63 is at an appropriate position with respect to the end 125B of the bundle assembly 125.

  When the positioning of the deformation means 63 with respect to the bundling assembly 125 is completed, the gripping portions 70, 70 of the gripping means 60 are held at the semi-grip position and the first slide body 75 of the locking means 61 is moved to the left. It is made to move and the latching of the 2nd latching part 123B and the latching | locking part 77 is cancelled | released. Then, as shown in FIG. 17A, the deforming means 63 is operated to move the elevating body 85 downward, and the first and second pressing levers 92 and 93 of the deforming portion 86 are used to identify the identification marker wire. It pushes down to 120 linear main-body part 121 from upper direction. As a result, as shown in FIG. 17B, the first pressing lever 92 presses the first portion 121A of the linear main body 121 against the outer peripheral portion 125A of the binding assembly 125, so that the deforming portion 86 is a rotating support shaft. It rotates clockwise in FIG. And since the 2nd press lever 93 pushes down the 2nd part 121B of the linear main-body part 121, this 2nd part 121B adjoins the edge part 125B of the bundling assembly 125, and this linear main-body part 121 is 1st. It bends between the part 121A and the second part 121B. Accordingly, the wire 120 for identification signs is formed into a shape along the end portion 125B from the outer peripheral portion 125A of the bundle assembly 125 by deforming the linear main body portion 121 into a substantially L shape.

  When the forming of the identification marker wire 120 by the deforming means 63 is completed, as shown in FIG. 18, after the gripping of the identification marker wire 120 is released with the gripping portions 70, 70 of the gripping means 60 as the release positions, The pressing means 64 is actuated to move the pressing portion 111 downward, and the first hooking portion 123A and the second hooking portion 123B of the hooking portion 123 floating from the outer peripheral portion 125A of the bundle assembly 125 are The pressing part 111 is pressed from above. Accordingly, the first hook portion 123A and the second hook portion 123B of the hook portion 123 are pressed against the outer peripheral portion 125A of the bundle assembly 125 and are formed along the outer peripheral portion 125A.

  Since the identification mark wire 120 of the embodiment formed by the identification mark wire forming apparatus 10 has the identification mark mounting portion 122 formed in an annular shape, the identification mark T attached to the identification mark mounting portion 122 is It can be prevented from falling off from the identification marker wire 120. Further, since the latching portion 123 is formed in a hook shape from the first latching portion 123A and the second latching portion 123B folded back at an acute angle with respect to the first latching portion 123A, the first latching portion The binding wire 127 constituting the binding assembly 125 is positioned on the inner peripheral surface side of the bent portion 123C located between the 123A and the second hooking portion 123B, and the second hooking portion 123B is attached to the identification mark. By bend | folding to the opposite side to the part 122, the latching part 123 can be appropriately wound around this binding wire 127, and can be latched. As a result, the identification marker wire 120 can be held without dropping from the binding assembly 125. Further, since the bent portion 123C is formed by bending into an inner peripheral surface shape that matches the outer peripheral surface of the binding wire 127, the first hook portion 123A and the second hook portion 123B are bent portions 123C. Can be easily wound when the hooking portion 123 is in close contact with the binding wire 127, and rattling between the hooking portion 123 and the binding wire 127 can be minimized.

The clearance H can be calculated. That is, as in the example, the measurement means 62 acquires measurement data of the outer surface shape in the circumferential direction of the outer peripheral portion 125A of the bundle assembly 125, and from the measurement data of the outer surface shape obtained by the measurement means 62, As shown in FIG. 19, a portion P <b> 1 (hereinafter referred to as “vertex”) P <b> 1 protruding from the outer peripheral portion 125 </ b> A of the bundle assembly 125 is extracted. Since the maximum width D of the binding object 126 is known in advance, a position separated in the circumferential direction by 1/2 (0.5D) of the maximum width D of the binding object 126 is defined as the gap H. Calculate the formation position. In the embodiment, since the binding object 126 is a round bar, the maximum width D is the diameter of the binding object 126, and at a position separated from the apex P1 in the circumferential direction by a radius (0.5D). A gap H is formed so as to be recessed from the apex P1 toward the outer peripheral portion 125A. Therefore, also in the gap position measuring method of the modified example, the position of the gap H formed between the outer peripheral portion 125A of the binding assembly 125 and the binding wire 127 is accurately calculated, and the hooking portion of the identification marker wire 120 is obtained. 123, the tip of the second hooking portion 123B can be accurately positioned and inserted into the gap H, and the identification marker wire 120 can be hooked to the binding wire 127 accurately and reliably.
