As shown in FIG. 6, the label wrapping device 1A rotates the peeling roller 31 and the conveyance roller 32 by driving a motor 96A (see FIG. 34). The peeling roller 31 rotates in the direction of arrow Y31, and conveys the peeling paper 10B held between it and the driven roller 33 in the direction of arrow Y11. As a result, the label tape 10 is fed out from the roll 100 in the direction of arrow Y12.

The driven roller 35 guides the label tape 10 along the peeling plate 37 while rotating according to the movement of the label tape 10. By bending the release paper 10B at the peeling point 370 of the release plate 37, the label 10A is peeled off from the release paper 10B. The peeled label 10A is pushed out in the direction of arrow Y13. The label 10A is guided forward by the driven roller 36 and enters between the conveyance roller 32 and the driven roller 34 from behind. The conveyance roller 32 rotates in the direction of arrow Y32 and conveys the label 10A held between it and the driven roller 34 forward. The label transported by the transport roller 32 moves in the direction of arrow Y14 to a position above the winding mechanism 6 disposed in front of the transport table 120.

Hereinafter, the conveyance direction (direction of arrow Y14) of the label 10A conveyed by the rotation of the conveyance roller 32 will be simply referred to as the conveyance direction. The transport direction corresponds to the forward direction. The upstream side in the conveyance direction corresponds to the rear side in the label winding device 1A.

The opening surrounded by the construction part 22 and the pair of side walls 23B corresponds to the discharge part 2B from which the release paper 10B is discharged to the outside of the label winding device 1A.

A pair of mounting parts 24 are provided inside the side plates 11A and 11B of the frame 11 and above the transport surface 120B of the transport table 120. The pair of mounting portions 24 protrude inward from the inner surfaces of the side plates 11A and 11B. A groove 24A is provided at the center of each of the pair of mounting portions 24 in the front-rear direction.

<Correction member 4>
As shown in FIGS. 4 and 5, the correction member 4 is provided downstream of the conveyance roller 32 and driven roller 34 of the conveyance mechanism 3. As shown in FIGS. 12 and 13, the correction member 4 includes a rotating body 4A and a rib 4B. The rotating body 4A is arranged above the third transport path R3. The rib 4B is arranged on the lower side with respect to the third conveyance path R3.

As shown in FIGS. 9 and 13, the rotating body 4A includes rotating bodies 41A, 41B, 41C, 41D, 41E, and 41F arranged in the left-right direction. The rotating bodies 41A-41F are disc-shaped and have irregularities on their peripheral ends. A rotating shaft 410 shown in FIG. 13 is inserted into a hole provided at the center of the rotating body 4A. The rotating shaft 410 has a rod shape and extends in the left-right direction. The rotating body 4A is rotatably supported by the cover 13 by a rotating shaft 410. As shown in FIG. 12, an axis 410C extending along the center of the rotating shaft 410 extends in the left-right direction and is disposed above the conveyance surface 130A of the cover 13. The lower end of the rotating body 4A slightly protrudes downward with respect to the conveying surface 130A.

As shown in FIG. 13, the rotating bodies 41A to 41F form a set of rotating bodies 411, 412, and 413, each consisting of two rotating bodies 4A having equal distances from the center of the conveying surface 130A in the left-right direction. The details are as follows. The rotating bodies 41A and 41F form a combined rotating body 411 that is spaced apart from each other by a distance L1 in the left-right direction. The rotating bodies 41B and 41E form a combined rotating body 412 that is spaced apart from each other by a distance L2 in the left-right direction. The rotating bodies 41C and 41D form a combined rotating body 413 that is spaced apart from each other by a distance L3 in the left-right direction. Each of the separation distances L1-L3 is different. The separation distance L1-L3 is the length in the left-right direction (hereinafter referred to as the width of the label 10A) when the label 10A, which may be used in the label winding device 1A, is conveyed along the third conveyance path R3. ). That is, the separation distances L1-L3 are each determined depending on the type of label 10A that may be used in the label wrapping device 1A.

As shown in FIG. 10, the center positions X1 and X2 of the rotating bodies 41B and 41C in the left-right direction are located between the conveyance rollers 32A and 32B in the left-right direction. The center positions X3 and X4 of the rotating bodies 41D and 41E in the left-right direction are located between the conveyance rollers 32B and 32C in the left-right direction. Therefore, the respective center positions X1 and X2 of the rotating bodies 41B and 41C included in the combined rotating body 412 and the respective center positions X3 and X4 of the rotating bodies 41D and 41E included in the combined rotating body 413 are both , are arranged at different positions from the conveyance rollers 32A-32C in the left-right direction.

As shown in FIGS. 10 and 13, the rib 4B has ribs 42A, 42B, and 42C arranged in the left-right direction. Ribs 42A-42C each protrude upward from conveying surface 120A. As shown in FIG. 10, the ribs 42A, 42B, and 42C extend parallel to each other along the conveyance direction. As shown in FIGS. 10 and 12, the longitudinal position of the rear end of the rib 4B and the longitudinal position of the front end of the conveyance roller 32B coincide at position P42. That is, the rear end of the rib 4B is arranged at the same position as the front end of the transport roller 32 in the transport direction. The front ends of the ribs 42A, 42B, and 42C extend to the front end of the conveyance surface 120A.

As shown in FIG. 13, the upper end of the rib 4B is located slightly above the lower end of the rotating body 4A in the vertical direction. Therefore, the rotating body 4A and the rib 4B overlap in the vertical direction at their respective tips. Further, as shown in FIG. 12, the positions of the rotating body 4A and a portion of the rib 4B in the front-rear direction coincide with each other. Therefore, the rotating body 4A and the rib 4B overlap in the left-right direction.

The label 10A peeled off from the release paper 10B by the peeling plate 37 of the transport mechanism 3 is transported along the third transport path R3 by the transport roller 32, and guided to the correction member 4 located downstream of the transport roller 32. . When the label 10A passes between the rotating body 4A and the rib 4B of the correction member 4, the upper adhesive surface contacts the rotating body 4A, and the lower surface contacts the rib 4B. The label 10A is conveyed while being deformed into a wave shape in which mountain-like curved parts and valley-like curved parts are alternately continuous in the left-right direction by the rotating body 4A and the ribs 4B. Note that the label 10A has a bending tendency due to being held in the state of the roll 100. On the other hand, the correction member 4 corrects the curvature by deforming the label 10A into a wave shape.

As shown in FIG. 12, a virtual plane extending horizontally through the upper end of the rib 4B is defined as a virtual plane M2. The virtual plane M2 coincides with the virtual plane M1 (see FIG. 7), which is a virtual plane passing through the peeling point 370 of the peeling plate 37 and the upper end of the conveyance roller 32. Hereinafter, the virtual planes M1 and M2 will be collectively referred to as the virtual plane M. The lower end of the rotating body 4A is arranged below the virtual plane M2. Therefore, the lower end of the rotating body 4A is located below the upper end of the conveyance roller 32.

Note that although a portion of the virtual plane M substantially coincides with the third transport route R3, strictly speaking, the two are different. The reason for this is that while the virtual plane M is a plane, the third conveyance path R3 is defined as an area through which the label 10A passes, and is deformed into a wave shape at a portion where the correction member 4 is provided. Furthermore, since the conveyance of the label 10A is regulated by a regulating section 8B, which will be described later, the downstream end of the third conveying route R3 coincides with the position of the regulating section 8B. On the other hand, the virtual plane M extends to the front of the restriction portion 8B.

<Label detection sensor 46>
As shown in FIG. 10, the conveying surface 120A is provided with recesses 16A, 16B, 16C, 16D, 16E, and 16F. The recesses 16A, 16B, 16C, 16D, 16E, and 16F are provided at positions facing the rotating bodies 41A-41F, respectively, when the cover 13 is placed in the closed position, and are spaced from the rotating bodies 41A-41F by a predetermined gap. It is slightly depressed downward from the conveying surface 120A. A rectangular through hole 160 is provided at a position adjacent to the right side of the rib 42B.

As shown in FIG. 14, a label detection sensor 46 is provided below the through hole 160. The label detection sensor 46 is an actuator type sensor and includes an actuator 46A and a detection section 46B. The actuator 46A has a rod shape, and its base end is swingably supported by the detection section 46B. The tip of the actuator 46A protrudes from the through hole 160 above the conveyance surface 120A. Specifically, the actuator 46A is swingable between a state in which the distal end portion is disposed above the upper end portion of the rib 4B and a state in which the distal end portion is disposed below the upper end portion of the rib 4B.

The detection unit 46B detects the swinging state of the actuator 46A, and outputs a signal according to the detection result to the CPU 91A (see FIG. 34). More specifically, the detection unit 46B outputs an OFF signal when the tip of the actuator 46A is placed above the top of the rib 4B, and the tip of the actuator 46A is placed above the top of the rib 4B. It also outputs an ON signal when it is placed below.

Note that when the downstream end of the label 10A enters between the rotary body 4A of the correction member 4 and the rib 4B in the third conveyance path R3, the tip of the actuator 46A is positioned further than the upper end of the rib 4B. The tip portion swings from the upper position to the position lower than the upper end of the rib 4B. Furthermore, when the upstream end of the label 10A withdraws from between the rotating body 4A of the correction member 4 and the rib 4B, the actuator 46A moves from a state in which the tip end is located below the upper end of the rib 4B. , the tip is swung so that it is located above the upper end of the rib 4B. Therefore, the CPU 91A can detect both the downstream and upstream ends of the label 10A on the third conveyance path R3 at the position of the correction member 4 according to the output signal of the label detection sensor 46. Note that the label detection sensor 46 may be an optical reflection type sensor, for example, instead of an actuator type sensor.

<Opening/closing member 5>
As shown in FIGS. 4 and 5, the opening/closing member 5 is disposed downstream of the correction member 4 and above the third conveyance path R3 (see FIG. 6). The opening/closing member 5 includes a base 51, a rotating body 52, and a rib 53.

As shown in FIGS. 15 to 17, the base 51 includes a cylindrical portion 51A, an extending portion 51B, and a pair of side plate portions 51C.

The pair of side plate portions 51C are provided at both left and right ends of the extension portion 51B, and are perpendicular to the left-right direction.

The opening/closing member 5 is swingably supported by the side plates 11A and 11B by a rotating shaft 50. The base portion 51 is swingable about an axis 50C that passes through the center of the rotating shaft 50 and extends in the left-right direction in a direction in which the lower end of the extension portion 51B moves in the front-rear direction. The position of the opening/closing member 5 in a state in which the lower end of the extending portion 51B has moved forward is referred to as a first position. The position of the opening/closing member 5 in which the lower end of the extending portion 51B has moved rearward is referred to as a second position. In addition, the cover part 13 is similarly supported by the side plates 11A and 11B by the rotating shaft 50 so that it can swing. That is, both the covering part 13 and the opening/closing member 5 swing around the common axis 50C.

The rotating body 52 includes rotating bodies 52A, 52B, 52C, 52D, and 52E arranged in the left-right direction. The rotating bodies 52A to 52E are disc-shaped and have irregularities on their peripheral edges. The rotating bodies 52A-52E protrude outward from the extending portion 51B at the front side and lower end portions of the rotating bodies 52A to 52E from approximately the center in the longitudinal direction.

A rotating shaft 520 shown in FIG. 10 is inserted into a hole provided at the center of the rotating body 52. The rotating shaft 520 has a rod shape and extends in the left-right direction. Both left and right end portions of the rotating shaft 520 are supported by the extending portion 51B of the base portion 51. The rotating body 52 is rotatably supported by the base 51 by a rotating shaft 520. As shown in FIG. 6, an axis 520C extending along the center of the rotating shaft 520 extends in the left-right direction. The rotating body 52 is rotatable about an axis 520C. The axis 520C is close to the top of the third conveyance path R3 (see FIGS. 6 and 12). Further, with the opening/closing member 5 in the first position (see FIG. 12), the lower end of the rotating body 52 contacts the virtual plane M from above. As shown in FIG. 18, the positions of the axis 50C of the rotating shaft 50 of the opening/closing member 5 and the axis 520C of the rotating body 52 in the front-rear direction substantially coincide with each other.

As shown in FIGS. 15 and 16, the ribs 53 include ribs 53A (531A, 532A), 53B (531B, 532B), 53C (531C, 532C), 53D (531D, 532D), and 53E arranged in the left-right direction. (531E, 532E). The ribs 53A to 53E each have a plate shape and are perpendicular to the left-right direction. The rib 531A is adjacent to the right side of the rotating body 52A, and the rib 532A is adjacent to the left side of the rotating body 52A. The rib 531B is adjacent to the right side of the rotating body 52B, and the rib 532B is adjacent to the left side of the rotating body 52B. The rib 531C is adjacent to the right side of the rotating body 52C, and the rib 532C is adjacent to the left side of the rotating body 52C. The rib 531D is adjacent to the right side of the rotating body 52D, and the rib 532D is adjacent to the left side of the rotating body 52D. The rib 531E is adjacent to the right side of the rotating body 52E, and the rib 532E is adjacent to the left side of the rotating body 52E. The direction in which the ribs 53 are adjacent coincides with the direction in which the axis 50C corresponding to the center of rotation of the rotating body 52 extends.

The shapes of ribs 53A-53E are the same. The peripheral end portion of the rib 53 extends from the vicinity of the upper end cylindrical portion 51A of the extension portion 51B in a direction inclined forward with respect to the opening/closing surface 510. The rib 53 is curved at the lower end and extends rearward. As shown in FIG. 18, the rib 53 is arranged in front of a plane passing through the axis 50C of the rotating shaft 50 of the opening/closing member 5 and the axis 520C of the rotating body 52. As shown in FIG.

As shown in FIG. 15, when the opening/closing member 5 is placed in the first position, the rib 53 covers the portion of the rotating body 52 that protrudes forward from the extension portion 51B from the left and right directions. That is, the rib 53 is a portion of the rotating body 52 that protrudes forward from the extension portion 51B, more specifically, the rib 53 is a portion of the rotating body 52 that extends from the upper end, front end, and lower end of the rotating body 52. It protrudes outward from the radial end of 52 (see FIG. 10). Note that the lower end of the rib 53 is located slightly above the lower end of the rotating body 52 (see FIG. 12). That is, the lower end of the rotating body 52 protrudes lower than the lower end of the rib 53.

As shown in FIGS. 4 and 5, a biasing portion 56 is provided on the rear side of the base portion 51 of the opening/closing member 5. As shown in FIG. As shown in FIG. 10, the biasing section 56 includes biasing sections 56A and 56B arranged in the left-right direction. The biasing parts 56A and 56B are compression coil springs, and are interposed between the rear surface of the base part 51 of the opening/closing member 5 and the covering part 13. The biasing portions 56A and 56B apply a forward biasing force to the opening/closing member 5. The opening/closing member 5 is urged by the urging section 56 from the second position (see FIG. 17) to the first position (see FIG. 15).

The label 10A whose curvature has been corrected by the correction member 4 is further conveyed by the conveyance roller 32 and passes below the opening/closing member 5. At this time, the opening/closing member 5 brings the rotating body 52 into contact with the label 10A conveyed along the third conveyance path R3 from above. Thereby, the opening/closing member 5 corrects the upward curvature of the label 10A, and moves the label 10A along the third conveyance path R3.

<Guide member 8A>
As shown in FIG. 1, the guide member 8A is arranged downstream with respect to the opening/closing member 5 and above with respect to the virtual plane M (see FIG. 12). As shown in FIG. 1, the guide member 8A includes a first part 81 that is close to the downstream side with respect to the opening/closing member 5, and a pair of second parts 82 that are arranged on both left and right sides of the first part 81. have The length of the first portion 81 in the left-right direction is approximately the same as the length of the opening/closing member 5 in the left-right direction.

As shown in FIGS. 15 and 17, the first portion 81 has an inclined surface 81A at the rear. The pair of second portions 82 each have an inclined surface 82A at the rear. The inclined surfaces 81A and 82A extend diagonally downward from the front end toward the rear end. The front ends of the inclined surfaces 81A and 82A, that is, the uppermost end portions 811 and 821 of the inclined surfaces 81A and 82A are located at the positions of the rotating shafts 50 that rotatably support the opening/closing member 5 in the vertical direction. located below. As shown in FIG. 18, the rear end portion of the inclined surface 81A of the first portion 81, that is, the lower end portion 812 disposed lowest among the inclined surfaces 81A is close to the third conveyance path R3.

The lower end of the opening/closing member 5 is close to the lower end 812 of the guide member 8A when the opening/closing member 5 is placed at the first position (see FIG. 14). At this time, the rib 53 comes into contact with the lower end 812 of the guide member 8A. On the other hand, the lower end of the opening/closing member 5 is spaced backward from the lower end 812 of the guide member 8A when the opening/closing member 5 is placed in the second position (see FIG. 19).

A cable 19 for wrapping the label 10A is attached to the label wrapping device 1A from above the guide member 8A while extending in the left-right direction. In this case, as shown in FIG. 18, the cable 19 is guided backward and diagonally downward along the inclined surfaces 81A and 82A of the guide member 8A, and is directed toward an insertion recess 62A (see FIG. 23) of the winding mechanism 6, which will be described later. You will be guided.

Note that when the opening/closing member 5 is in the first position, the end of the rib 53 in the opposite direction (diagonally downward in the front) to the moving direction (diagonally downward in the rear) of the cable 19 guided by the guide member 8A is connected to the rotating body. It protrudes outward from the radial end of 52. Therefore, the cable 19 comes into contact with the rib 53 of the opening/closing member 5 in the process of being guided toward the insertion recess 62A of the winding mechanism 6 by the guide member 8A. An external force is applied to the lower end of the opening/closing member 5 from above by a cable 19. In this case, as shown in FIG. 19, the opening/closing member 5 moves from the first position to the second position by moving the lower end portion rearward against the urging force of the urging portion 56. As a result, the opening 620B of the winding mechanism 6, which will be described later, is switched from a closed state (see FIG. 18) to an open state (see FIG. 19) by the opening/closing member 5.

<Regulation part 8B>
As shown in FIGS. 18 and 19, a regulating portion 8B is formed below the lower end portion 812 of the first portion 81 of the guide member 8A. The regulating portion 8B has a recessed portion 85 that is recessed toward the front. The recess 85 extends linearly in the left-right direction. The recess 85 has regulating walls 86, 87, and 88 as inner walls.

The regulating wall 86 corresponds to the bottom wall of the recess 85 and is orthogonal to the front-rear direction. The regulating wall 86 is located on the downstream side with respect to the downstream end of the third conveyance path R3, and intersects with the virtual plane M. The regulating wall 87 is a portion of the side wall of the recess 85 that extends from the upper end of the regulating wall 86 . The regulating wall 87 intersects with the vertical direction and extends diagonally rearward and upward from the upper end of the regulating wall 86 toward the lower end 812 of the guide member 8A. The regulating wall 87 is arranged above the third conveyance path R3 and the virtual plane M. The regulating wall 88 is a portion of the side wall of the recess 85 that extends from the lower end of the regulating wall 86 . The regulating wall 88 is perpendicular to the vertical direction and extends horizontally from the lower end of the regulating wall 86 toward the rear.

The rotation shaft 671 is supported by the first bottom part 621 and the second bottom part 622 near the upstream side of the opening 620B of the insertion recess 62A. Therefore, the second base end portion 67A is arranged near the upstream side of the opening 620B of the insertion recess 62A. The distance in the stretching direction S from the opening 620B to the second base end 67A is shorter than the distance in the stretching direction S from the bottom 620A to the second base end 67A.

As shown in FIGS. 20 and 21, the side surface portion 63A is provided with a rib 630 that protrudes in a direction opposite to the insertion direction S1 and extends in the left-right direction. The rib 630 has a tapered surface that becomes thinner toward the tip. The rear surface of the lower end of the first arm member 66 is in contact with the front surface of the tapered surface of the rib 630 due to the urging force of the first springs 681 and 682. Similarly, the front surface of the lower end of the second arm member 67 is in contact with the rear surface of the tapered surface of the rib 630 due to the biasing force of the second springs 691 and 692.

As shown in FIG. 24, the first arm member 66 has a first convex portion 66E that protrudes toward the second arm member 67 side. The first convex portion 66E is adjacent to the first proximal end portion 66A side of the first opposing end portion 660 of the first arm member 66 with respect to the first inclined portion 66C. A straight line T1 is defined that connects the rotation axis 661 of the first arm member 66 and the connection point of the first inclined part 66C and the second inclined part 66D.

The second convex portion 67E is adjacent to the second proximal end portion 67A side of the second opposing end portion 670 of the second arm member 67 with respect to the first inclined portion 67C. A straight line T2 is defined that connects the rotation axis 671 of the second arm member 67 and the connection point between the first inclined part 67C and the second inclined part 67D. In this case, the protrusion amount Q2 of the second convex portion 67E is defined as the distance between the straight line T2 and the second convex portion 67E. In this case, the protrusion amount Q2 of the second convex portion 67E is larger than the protrusion amount Q1 of the first convex portion 66E.

As shown in FIG. 23, the cable 19 guided downward by the guide member 8A enters the insertion recess 62A from the opening 620B. At this time, the cable 19 follows the direction in which it is guided along the inclined surfaces 81A and 82A of the guide member 8A, and enters while moving diagonally rearward. Therefore, the cable 19 first contacts the second convex portion 67E (see FIG. 24) of the second arm member 67, and moves the second arm member 67 backward against the urging force of the second springs 691 and 692. move it. The cable 19 is guided downward by contacting the second convex portion 67E.

Next, the cable 19 contacts the first convex portion 66E (see FIGS. 24 and 25) of the first arm member 66, and moves the first arm member 66 forward against the urging force of the first springs 681 and 682. move it. Cable 19 moves further downward. As shown in FIGS. 24 and 25, the cable 19 is held between the inclined portion 662 of the first arm member 66 and the inclined portion 672 of the second arm member 67 from the front and back directions. Hereinafter, the position of the cable 19 held by the first arm member 66 and the second arm member 67 will be referred to as the winding position Pm. The longitudinal direction of the cable 19 disposed at the winding position Pm extends in the left-right direction and is orthogonal to the insertion direction S1 of the cable 19.

As shown in FIG. 24, a case is illustrated in which a cable 19A having a relatively small diameter is inserted into the insertion recess 62A. In this case, the cable 19A is held in a state where the first sloped portions 66C, 67C and the second sloped portions 66D, 67D of the first arm member 66 and the second arm member 67 are in contact with each other. When the cable 19A is held by the first arm member 66 and the second arm member 67, the axis 6A corresponding to the rotation center of the winding mechanism 6 and the center line C of the cable 19A substantially coincide with each other.

On the other hand, as shown in FIG. 25, a case is illustrated in which a cable 19B having a relatively large diameter is inserted into the insertion recess 62A. In this case, the cable 19B is held between the first inclined portions 66C and 67C of the first arm member 66 and the second arm member 67, and the bottom portion 620A of the insertion recess 62A. With the cable 19A held by the first arm member 66, the second arm member 67, and the bottom 620A of the insertion recess 62A, the axis 6A corresponding to the rotation center of the winding mechanism 6 and the center line C of the cable 19B It almost matches. In other words, the winding mechanism 6 can always hold the cable 19 in a state where the center line C of the cable 19 and the axis 6A substantially coincide with each other, regardless of the diameter of the cable 19. Note that since the label 10A is not shown in FIG. 25, there is a slight gap equal to the thickness of the label 10A between the cable 19 and the bottom 620A.

Further, as shown in FIG. 24, the cable 19 is inserted into the insertion recess 62A together with the label 10A. The label 10A is interposed between the first arm member 66 and the second arm member 67 and the cable 19 while the cable 19 is held at the winding position Pm. The label 10A is wrapped around and attached to approximately the lower half of the cable 19, that is, approximately the lower half of the outer peripheral surface of the cable 19. In this state, the label wrapping device 1A rotates the wrapping mechanism 6 by driving the motor 96B (see FIG. 34). The winding mechanism 6 rotates around the cable 19 around the axis 6A. In this case, the label 10A is guided to be wrapped around the cable 19 placed at the wrapping position Pm. As a result, the label 10A is wrapped around the cable 19 and attached.

<Wrapping sensor 69>
As shown in FIG. 20, a protrusion 69A that protrudes outward is provided near the front of the side surface 63A of the base 61. As shown in FIG. A wrap sensor 69 is provided diagonally below the front of the base 61 on the side plate 11B of the frame 11 (see FIG. 1). The winding sensor 69 is a contact type position sensor that can detect the proximity of the protrusion 69A. The winding sensor 69 outputs an OFF signal to the CPU 91A (see FIG. 34) when the protrusion 69A is in a separated state. The winding sensor 69 outputs an ON signal to the CPU 91A (see FIG. 34) when the protrusion 69A approaches. Therefore, the CPU 91A can detect the number of times the protrusion 69A is contacted by accumulating the number of times the winding sensor 69 outputs an ON signal, and can specify the number of rotations of the winding mechanism 6.

Note that the winding mechanism 6 is placed at the initial position with the protrusion 69A close to the winding sensor 69. Therefore, when the winding sensor 69 outputs an ON signal, the CPU 91A can determine that the winding mechanism 6 is located at the initial position.

The holding members 7A and 7B have a symmetrical structure with respect to a plane of symmetry that passes through the center of the label winding device 1A in the left-right direction and is perpendicular to the left-right direction.

The holding members 7A and 7B guide the cable 19 that has entered the insertion recess 62A (see FIG. 20) of the wrapping mechanism 6 downward to the wrapping position Pm (see FIG. 23) at two positions separated in the left-right direction. , holds the cable 19 at the winding position Pm.

The inclined portion 76A of the guiding portion 76 and the inclined portion 77A of the guiding portion 77 apply a downward force to the cable 19 in accordance with the urging force of the urging portion 73. Thereby, the cable 19 is guided toward the lower winding position Pm.

Until the cable 19 reaches the winding position Pm, the first pinching member 71 and the second pinching member 72 swing in the direction of returning to their original positions due to the biasing force of the biasing portion 73. Further, the inclined portion 76B of the guiding portion 76 and the inclined portion 77B of the guiding portion 77 restrict further downward movement of the cable 19. As a result, the cable 19 is sandwiched from the front and rear directions by the guide portions 76 and 77 of the first and second sandwiching members 71 and 72, and is held at the winding position Pm.

Here, the center line C of the cable 19 arranged at the winding position Pm is close to the straight line Z connecting the bending part 76C of the guiding part 76 and the bending part 77C of the guiding part 77. Therefore, the center line C of the cable 19 is The positions of are almost the same. Note that the position of the center line C of the cable 19 held by the first pinch member 71 and the second pinch member 72 is the axis 6A (see FIGS. 24 and 25) corresponding to the rotation center of the winding mechanism 6. Approximately matches the position.

On the other hand, when the cable 19 is detached from the label wrapping device 1A, an upward force is applied to the cable 19 at the wrapping position Pm. In the process of the cable 19 exiting from the insertion recess 62A of the winding mechanism 6, the cable 19 contacts the inclined portion 76A of the first pinching member 71 and the inclined portion 77A of the second pinching member 72 from below. The first pinching member 71 swings clockwise against the biasing force of the biasing portion 73 in response to the force applied from the cable 19 to the inclined portion 76A.

At this time, as shown in FIG. 31, the protrusion 71D of the first clipping member 71 contacts the protrusion 51D of the opening/closing member 5 from the front and pushes the opening/closing member 5 backward. As shown in FIG. 32, the opening/closing member 5 moves from the first position to the second position, and the opening 620B of the insertion recess 62A opens. The cable 19 passes through the open opening 620B and is taken out from the insertion recess 62A.

After the cable 19 is withdrawn, the first pinching member 71 is rotated counterclockwise by the urging force of the urging portion 73 and returns to its original position. At the same time, the opening/closing member 5 moves from the second position to the first position, and the opening 620B of the insertion recess 62A is closed by the opening/closing member 5. Further, the second pinching member 72 is rotated clockwise by the biasing force of the biasing portion 73 and returns to its original position.

<Detection unit 26>
As shown in FIG. 2, a detection section 26A is provided on the right side of the holding member 7A. A detection section 26B is provided on the left side of the holding member 7B. The detection units 26A and 26B are separated from each other in the left-right direction. The configurations of the detection units 26A and 26B are the same. Hereinafter, the detection section 26A will be explained, and the explanation of the detection section 26B will be omitted. The detection units 26A and 26B are collectively referred to as a detection unit 26.

As shown in FIG. 33, the detection unit 26A is arranged above the swing shafts 70 of the first and second pinching members 71 and 72, and is arranged on the right side of the cover 117A. The detection unit 26 is a contact type displacement sensor and includes a main body 27 and a movable piece 28 .

The main body portion 27 has a box shape and is fixed to the right side of the cover 117A. A cover 118A (see FIG. 26) provided on the right side of the cover 117A covers the main body portion 27 from the right side. The movable piece 28 has an elongated plate shape and extends rearward and diagonally upward from the main body portion 27. The movable piece 28 is arranged above the bottom of the recess 119A of the cover 117A. A lower end portion of the movable piece 28 is swingably supported by the main body portion 27 . The main body part 27 has a built-in switch that can detect that the movable piece 28 swings and its tip moves downward.

When the cable 19 is inserted into the insertion recess 62A of the winding mechanism 6, the cable 19 comes into contact with the movable piece 28 of each of the detection parts 26A and 26B. With the cable 19A disposed at the winding position Pm, the movable piece 28 is pushed from above by the cable 19 to swing, and its tip moves downward. The main bodies 27 of the detection units 26A and 26B detect that the movable piece 28 has moved, and output an ON signal to the CPU 91A (see FIG. 34). On the other hand, the main bodies 27 of each of the detection units 26A and 26B output an OFF signal to the CPU 91A with the movable piece 28 moved upward. Thereby, the CPU 91A can detect the cable 19A at the wrapping position Pm both on the right side of the holding member 7A and on the left side of the holding member 7B.

<Electrical configuration>
The electrical configuration of the label wrapping device 1A will be described with reference to FIG. 34. The label wrapping device 1A includes a CPU 91A, a ROM 91B, a RAM 91C, a flash memory 91D, and an input/output interface 91E, which are connected via a data bus 92. The CPU 91A centrally controls the label wrapping device 1A. The ROM 91B stores constants necessary when the CPU 91A executes various programs. The RAM 91C stores temporary data generated when the CPU 91A executes processing. The flash memory 91D stores programs executed by the CPU 91A, variables (first distance H1, second distance H2, diameter of cable 19), and the like.

A notification section 93A, an input section 93B, drive circuits 95A, 95B, detection sections 26A, 26B, a label detection sensor 46, a wrapping sensor 69, and an external interface (I/F) 94 are connected to the input/output interface 91E. . The notification section 93A is an LCD that can display a screen showing the status of the label wrapping device 1A. The input section 93B is a button for operating the label wrapping device 1A. Drive circuit 95A is an electronic circuit for driving motor 96A. Drive circuit 95B is an electronic circuit for driving motor 96B. The external I/F 94 connects to and communicates with an external terminal 94A (not shown). For example, the CPU 91A can update the program by storing the program received from the external terminal 94A in the flash memory 91D. The external terminal 94A is a general-purpose personal computer (PC) or a mobile terminal.

<Main processing>
The main processing will be explained with reference to FIGS. 35 and 36. The main process is started when the CPU 91A reads and executes a program stored in the flash memory 91D when an operation for starting the operation of wrapping the label 10A around the cable 19 is input via the input unit 93B. Ru.

As shown in FIG. 35, the CPU 91A first selects the first portion 103 of the label 10A (see first distance H1(B) in FIG. 37) and the second distance H2 of the second portion 104 (see FIG. 37(B)). ) is read and acquired from the flash memory 91D (S11). The first portion 103, the second portion 104, the first distance H1, and the second distance H2 are each defined as follows.

As shown in FIG. 37(B), after the conveyance of the label 10A by the conveyance roller 32 is completed, in the process of attaching the cable 19 to the label winding device 1A, the cable 19 is attached to the winding mechanism along the guide member 8A. A case where the user is guided downward toward 6 is illustrated. In this case, the cable 19 is attached to a part of the adhesive surface of the label 10A (hereinafter referred to as the attachment section 10C). Hereinafter, the state in which the cable 19 is attached to the attachment portion 10C of the label 10A will be referred to as an initial state. The position of the cable 19 in the initial state is located above the winding position Pm.

In the initial state, the first portion 103 corresponds to a portion between the downstream end of the label 10A (hereinafter referred to as the first end 101) and the sticking portion 10C. The first distance H1 corresponds to the distance of the first portion 103 in the front-rear direction. In the initial state, the second portion 104 corresponds to a portion between the upstream end of the label 10A (hereinafter referred to as the second end 102) and the sticking portion 10C. The second distance H2 is the distance of the second portion 104 in the front-rear direction. The first distance H1 is shorter than the second distance H2. In addition, in the initial state, each position of the pasting part 10C, the first end 101, and the second end 102 can be specified in advance as a predetermined position in the label winding device 1A. Therefore, the first distance H1 and the second distance H2 are stored in advance in the flash memory 91D as initial setting values of the label wrapping device 1A.

As shown in FIG. 35, the CPU 91A reads and acquires the diameter of the cable 19 from the flash memory 91D (S13). Note that, for example, the user may previously input the diameter of the cable 19 to the label wrapping device 1A via an external terminal 94A connected to the label wrapping device 1A. The CPU 91A may receive the diameter of the cable 19 via the external I/F 94 and store it in the flash memory 91D. When executing the process of S13, the CPU 91A may read and obtain the diameter of the cable 19 stored in advance in the flash memory 91D as described above.

The CPU 91A determines the first predetermined amount and the second predetermined amount based on the first distance H1 and the second distance H2 obtained in the process of S11 and the diameter of the cable 19A obtained in the process of S13 (S15). The first predetermined amount is the amount of rotation when the winding mechanism 6 is rotated in the clockwise direction (referred to as a first direction Y81, see FIG. 37(E)) in the process of S33 (see FIG. 36), which will be described later. The first predetermined amount indicates the rotation angle of the winding mechanism 6. The second predetermined amount is the amount of rotation when the winding mechanism 6 is rotated in the counterclockwise direction (referred to as a second direction Y83, see FIG. 37(F)) in the process of S35 (see FIG. 36), which will be described later. The second predetermined amount indicates the number of rotations of the winding mechanism 6. A method for determining the first predetermined amount and the second predetermined amount will be described later.

The CPU 91A determines whether the cable 19 is detected by either of the detection units 26A or 26B and an ON signal is output from either of the detection units 26A or 26B (S17). Note that in this state, peeling and conveyance of the label 10A have not been completed, and preparations for wrapping and pasting the label 10A around the cable 19 have not been completed. Therefore, when the CPU 91A determines that an ON signal has been output from either of the detection units 26A and 26B (S17: YES), the CPU 91A advances the process to S55 (see FIG. 36). As shown in FIG. 36, the CPU 91A displays a message on the notification section 93A to notify the user that the operation of wrapping the label 10A around the cable 19 cannot be started (S55). The CPU 91A ends the main processing.

On the other hand, when the cable 19 is not placed at the wrapping position, it is possible to start the operation of wrapping and pasting the label 10A around the cable 19. As shown in FIG. 35, when the CPU 91A determines that the OFF signal has been output from both the detection units 26A and 26B (S17: NO), the CPU 91A advances the process to S19.

The CPU 91A determines whether or not the winding mechanism 6 is placed at the initial position, based on the output signal from the winding sensor 69. When the winding sensor 69 outputs an OFF signal, the CPU 91A determines that the winding mechanism 6 is not located at the initial position (S19: NO). In this case, the CPU 91A controls the drive circuit 95B and rotates the motor 96B so that the winding mechanism 6 rotates (S21). The CPU 91A returns the process to S19 and continues to monitor the output signal from the winding sensor 69. When the winding sensor 69 outputs an ON signal, the CPU 91A determines that the winding mechanism 6 is located at the initial position (S19: YES). In this case, since the opening 620B of the insertion recess 62A of the winding mechanism 6 faces upward, the cable 19 can be inserted into the insertion recess 62A. The CPU 91A controls the drive circuit 95B to stop the rotation of the motor 96B and the rotation of the winding mechanism 6. The CPU 91A advances the process to S23.

The CPU 91A controls the drive circuit 95A to start rotating the motor 96A (S23). The rotational driving force of the motor 96A is transmitted to the peeling roller 31 via the plurality of gears 970 of the transmission section 97, and the rotation of the peeling roller 31 is started. As shown in FIG. 6, the peeling roller 31 rotates to convey the release paper 10B held between it and the driven roller 33 in the direction of arrow Y11, and feeds out the label tape 10 from the roll 100 in the direction of arrow Y12. . As the release paper 10B bends at the release point 370 of the release plate 37, the label 10A is peeled off from the release paper 10B. The peeled label 10A is pushed out in the direction of arrow Y13. The label 10A enters between the conveyance roller 32 and the driven roller 34.

Further, the rotational driving force of the motor 96A is transmitted to the conveyance roller 32 via the plurality of gears 980 of the transmission section 98 and the one-way clutch 98A, and the rotation of the conveyance roller 32 is started. The conveyance roller 32 rotates to convey the label 10A in the conveyance direction (direction of arrow Y14) along the third conveyance path R3.

The CPU 91A determines whether the label detection sensor 46 provided at the position of the correction member 4 on the third conveyance path R3 has output an ON signal (S25). When the label detection sensor 46 outputs an OFF signal, the first end 101 (see FIG. 37(B)), which is the downstream end of the label 10A peeled off from the release paper 10B, is at the position of the correction member 4. This means that it has not passed through. Therefore, when the CPU 91A determines that the OFF signal has been output from the label detection sensor 46 (S25: NO), the CPU 91A returns the process to S25 and continues to monitor the output signal of the label detection sensor 46.

On the other hand, in response to the first end 101 of the label 10A peeled off from the release paper 10B passing the position of the correction member 4, the label detection sensor 46 outputs an ON signal. When the CPU 91A determines that the ON signal is output from the label detection sensor 46 (S25: YES), the CPU 91A determines the timing for stopping the conveyance of the label 10A (S27).

More specifically, the CPU 91A calculates the transport time required for the transport roller 32 to transport the label 10A by the length in the front-rear direction from the actuator 46A of the label detection sensor 46 to the regulating portion 8B. The CPU 91A determines the timing after the transport time has elapsed from the current time as the timing to stop transporting the label 10A. As a result, the CPU 91A transports the label 10A after the first end 101 of the label 10A passes the position of the label detection sensor 46 until the first end 101 of the label 10A contacts the regulation wall 86, and then stops. Yes, it is possible (S27). When conveyance of the label 10A is stopped at this timing, the first end 101 of the label 10A is located downstream of the opening 620B of the insertion recess 62A of the winding mechanism 6.

The CPU 91A controls the drive circuit 95A in accordance with the transport stop timing determined in the process of S27, and stops the rotation of the motor 96A started in the process of S19 (S29). As a result, the rotation of the conveyance roller 32 is stopped. As shown in FIG. 36(A), the label 10A is conveyed to a position where it closes the opening 620B of the insertion recess 62A of the winding mechanism 6, and then stopped.

Further, in response to the rotation of the motor 96A being stopped, the rotation of the peeling roller 31 is also stopped. In this state, the second end 102, which is the upstream end of the label 10A, is located downstream of the peeling plate 37. In other words, the label 10A is already peeled off from the release paper 10B over the entire area from the first end 101 to the second end 102. Further, a part of the downstream end of the label 10A' next to the label 10A of the label tape 10 is peeled off by the peeling plate 37.

As shown in FIG. 36(A), the user places the cable 19 above the guide member 8A in order to attach the cable 19 for wrapping the label 10A to the label wrapping device 1A. As shown in FIG. 36(B), the user moves the cable 19 downward along the inclined surfaces 81A and 82A of the guide member 8A (arrow Y71). The cable 19 comes into contact with the rib 53 of the opening/closing member 5 while being guided toward the insertion recess 62A of the winding mechanism 6 by the guide member 8A. External force is applied to the lower end of the opening/closing member 5. The opening/closing member 5 moves from the first position to the second position against the urging force of the urging section 56 (arrow Y73). As a result, the opening 620B of the winding mechanism 6 is switched from the closed state (see FIG. 37(A)) to the open state (see FIG. 37(B)) by the opening/closing member 5. The cable 19 is attached to the attachment portion 10C of the label 10A.

As shown in FIG. 37(C), the user further moves the cable 19 downward. As a result, the cable 19 passes through the opening 620B and is inserted into the insertion recess 62A of the winding mechanism 6 from above (arrow Y75). As shown in FIG. 37(D), the cable 19 moves within the insertion recess 62A along the insertion direction S1 (see FIG. 22) from the opening 620B to the bottom 620A (arrow Y77). The cable 19 is held between the first and second pinch members 71 and 72 (see FIG. 26, etc.) of the holding member 7, and the first arm member 66 and second arm member 67 of the winding mechanism 6, and is not wound. It is held at position Pm. Further, since the label 10A is attached to the cable 19 at the attachment part 10C, the label 10A is also inserted into the insertion recess 62A of the winding mechanism 6 as the cable 19 moves. The second portion 104 of the label 10A moves downstream on the third conveyance path R3 and enters the insertion recess 62A. Note that the one-way clutch 98A of the transmission section 98 interrupts the connection between the motor 96A and the conveyance roller 32 when the conveyance roller 32 rotates while the motor 96A is stopped. Therefore, movement of the second portion 104 of the label 10A to the downstream side is not hindered by the motor 96A.

The label 10A is interposed between the first arm member 66 and the second arm member 67 and the cable 19 while the cable 19 is held at the winding position Pm. The label 10A is wrapped around and attached to approximately the lower half of the cable 19.

In response to the cable 19 being inserted into the insertion recess 62A of the winding mechanism 6, the force applied by the cable 19 to the lower end of the opening/closing member 5 is released. The opening/closing member 5 moves from the second position to the first position by the urging force of the urging section 56 (arrow Y79). Thereby, the opening 620B of the winding mechanism 6 returns to the state where it is closed by the opening/closing member 5.

As shown in FIG. 36, the CPU 91A determines whether both of the detection units 26A and 26B output an ON signal (S31). When both the detection units 26A and 26B output OFF signals, the cable 19 has not reached the bottom 620A of the insertion recess 62A and is not placed at the winding position Pm. Furthermore, when only one of the detection sections 26A and 26B outputs an OFF signal and the other outputs an ON signal, the cable 19 is inclined with respect to the left and right direction, and the cable 19 is normally placed at the winding position Pm. It means that it is not placed in the state.

Therefore, when the CPU 91A determines that at least one of the detection units 26A and 26B has output an OFF signal (S31: NO), the CPU 91A advances the process to S51. The CPU 91A determines whether only one of the detection units 26A and 26B is outputting an OFF signal (S51). When both of the detection units 26A and 26B output OFF signals (S51: NO), the CPU 91A returns the process to S27 and continuously monitors the signals output from the detection units 26A and 26B.

On the other hand, if the CPU 91A determines that only one of the detection units 26A and 26B is outputting an OFF signal (S51: YES), the CPU 91A first determines that only one of the detection units 26A and 26B is outputting an OFF signal. It is determined whether a predetermined time has elapsed from the determined timing (S53). If the CPU 91A determines that the predetermined time has not elapsed (S53: NO), the process returns to S31 and continues to monitor the signals output from the detection units 26A and 26B. On the other hand, if the CPU 91A determines that a predetermined period of time has elapsed since the timing at which it was first determined that only one of the detection units 26A and 26B outputs an OFF signal (S53: YES), the cable 19 is correctly attached. In order to notify the user that the information is not available, a message is displayed on the notification unit 93A to notify the user (S55). The CPU 91A ends the main processing.

On the other hand, when both the detection units 26A and 26B output ON signals, the cable 19 is placed at the winding position Pm at each of the two positions of the detection units 26A and 26B. It is normally located at Pm. When the CPU 91A determines that both the detection units 26A and 26B have outputted the ON signal (S31: YES), the CPU 91A advances the process to S33.

The CPU 91A controls the drive circuit 95B and rotates the motor 96B so that the winding mechanism 6 rotates in the first direction Y81 (see FIG. 37(E)) (S33). Further, the CPU 91A controls the drive circuit 95B so that the rotational speed of the winding mechanism 6 rotated by the motor 96B becomes the first speed. The CPU 91A rotates the winding mechanism 6 by the first predetermined amount (rotation angle) determined in the process of S15, and then stops the rotation of the winding mechanism 6 (S35).

As shown in FIG. 37(E), by rotating the wrapping mechanism 6 in the first direction Y81, the first portion 103 of the label 10A is wrapped and attached to the cable 19 by the first pinching member 71. Note that the first predetermined amount when the wrapping mechanism 6 rotates in the first direction Y81 corresponds to the amount of rotation required to wrap the first portion 103 of the label 10A around the cable 19. That is, through the process of S15 (see FIG. 35), the CPU 91A determines the rotation angle required to wrap the first portion 103 of the label 10A around the cable 19 in accordance with the diameter of the cable 19 and the length of the first portion 103. The distance is determined based on the first distance H1 (see FIG. 37(B)).

Next, the CPU 91A controls the drive circuit 95B to rotate the motor 96B so that the winding mechanism 6 rotates in the second direction Y83 (see FIG. 37(F)) (S37). Further, the CPU 91A controls the drive circuit 95B so that the rotational speed of the winding mechanism 6 rotated by the motor 96B becomes a second speed faster than the first speed.

The CPU 91A determines whether the winding mechanism 6 has rotated by the second predetermined amount (number of rotations) determined in the process of S15, based on the number of times the winding sensor 69 outputs an ON signal. When the winding sensor 69 outputs an ON signal, the CPU 91A accumulates the number of revolutions of the winding mechanism 6. If the cumulative number of rotations is less than the second predetermined number (S39: NO), the CPU 91A returns the process to S37 and continues controlling the winding mechanism 6 to rotate in the second direction Y83. When the cumulative number of rotations is equal to or greater than the second predetermined number (S39: YES), the CPU 91A controls the drive circuit 95B to stop the rotation of the winding mechanism 6 (S41). The CPU 91A returns the process to S11.

As shown in FIG. 37(F), as the wrapping mechanism 6 rotates in the second direction Y83, the second portion 104 of the label 10A is wrapped around the cable 19 by the first pinching member 71 and the second pinching member 72. and pasted. Further, the second predetermined amount when the winding mechanism 6 rotates in the second direction Y83 corresponds to the amount of rotation required to wind the second portion 104 of the label 10A around the cable 19. That is, through the process of S15, the CPU 91A calculates the number of rotations required to wrap the second portion 104 of the label 10A around the cable 19 by determining the second distance H2 corresponding to the diameter of the cable 19 and the length of the second portion 104. (See FIG. 37(B)).

The cable 19 to which the label 10A is wrapped and attached is moved upward from the wrapping position Pm in order to be detached from the label wrapping device 1A. In the process of the cable 19 exiting from the insertion recess 62A of the winding mechanism 6, the cable 19 comes into contact with the inclined portion 76A of the first clipping member 71 from below, and the first clipping member 71 swings clockwise. At this time, as shown in FIG. 31, the protrusion 71D of the first clipping member 71 contacts the protrusion 51D of the opening/closing member 5 from the front and pushes the opening/closing member 5 backward. As shown in FIG. 32, the opening/closing member 5 moves from the first position to the second position, and the opening 620B of the insertion recess 62A opens. The cable 19 passes through the open opening 620B and is taken out from the insertion recess 62A.

After the cable 19 exits, the first clipping member 71 is rotated counterclockwise by the biasing force of the biasing portion 73, and the second clipping member 72 is rotated clockwise by the biasing force of the biasing portion 73. Both return to their original positions. Further, the opening/closing member 5 moves from the second position to the first position by the urging force of the urging section 56, and closes the opening 620B of the insertion recess 62A of the winding mechanism 6.

<Actions and effects of this embodiment>
In response to the detection unit 26 detecting that the cable 19 is at the wrapping position Pm (S31: YES), the label wrapping device 1A wraps the label 10A around the cable 19 using the wrapping mechanism 6 (S33, S37). . Therefore, the label winding device 1A can prevent the winding mechanism 6 from winding the label 10A in a state where the cable 19 is deviated from the winding position Pm. Therefore, the label winding device 1A can drive the winding mechanism 6 while the cable 19 is appropriately placed at the winding position Pm, so that the label 10A can be wound around the cable 19 appropriately.

The label wrapping device 1A includes detection sections 26A and 26B. The detection units 26A and 26B can detect the cable 19 at two positions separated in the longitudinal direction of the cable 19. When the detection units 26A and 26B each detect the cable 19 (S31: YES), the label wrapping device 1A determines that the cable 19 is at the wrapping position Pm, and drives the wrapping mechanism 6 to wrap the cable 19. Wrap label 10A around it. On the other hand, the label wrapping device 1A does not drive the wrapping mechanism 6 when the longitudinal direction of the cable 19 is inclined with respect to the left-right direction and the cable 19 is not normally placed at the wrapping position Pm. Therefore, the label winding device 1A can more accurately detect that the cable 19 is at the winding position Pm using the detection units 26A and 26B, so that the label 10A can be wrapped around the cable 19 in a good manner.

The holding member 7 of the label wrapping device 1A guides the cable 19 in the insertion direction S1 to the wrapping position Pm, and holds the cable 19 at the wrapping position Pm. That is, the holding member 7 has a function of not only holding the cable 19 at the wrapping position Pm but also guiding the cable 19 to the wrapping position Pm. Therefore, in the label wrapping device 1A, the holding member 7 can facilitate the user's work of attaching the cable 19 to the wrapping position Pm.

The holding member 7 includes a first clipping member 71 and a second clipping member 72 that sandwich the cable 19, and a biasing portion 73 that biases the first clipping member 71 and the second clipping member 72. The holding member 7 guides the cable 19 in the insertion direction S1 and holds it at the wrapping position Pm using the gap between the first pinching member 71 and the second pinching member 72. That is, in the label wrapping device 1A, the functions of guiding and holding the cable 19 can be realized by the first clipping member 71 and the second clipping member 72. Therefore, the label wrapping device 1A can guide and hold the cable 19 to the wrapping position Pm with a simple configuration.

The first inclined portion 711 of the first pinching member 71 is inclined in a direction away from the second pinching member 72 as it goes toward the opposite side (upper side) of the insertion direction S1. Therefore, by bringing the cable 19 into contact with the first inclined portion 711, the user can correct the posture of the cable 19 so that the cable 19 can easily move in the insertion direction S1 to the wrapping position Pm. Therefore, the label wrapping device 1A can facilitate the user's operation of arranging the cable at the wrapping position Pm. Furthermore, the second inclined portion 721 of the second pinching member 72 is inclined in a direction away from the first pinching member 71 as it goes toward the opposite side (upper side) of the insertion direction S1. In this way, the label wrapping device 1A further facilitates the user's operation of arranging the cable 19 at the wrapping position Pm by providing the inclined portions in both the first pinching member 71 and the second pinching member 72. can.

Note that the distance in the insertion direction S1 between the first inclined portion 711 and the wrapping position Pm is larger than the distance in the insertion direction S1 between the second inclined portion 721 and the wrapping position Pm. That is, the first inclined part 711 is arranged above the second inclined part 721. In this case, when the user performs an operation to arrange the cable 19 at the wrapping position Pm, the cable 19 first comes into contact with the first inclined part 711 of the first pinching member 71, and then the second inclined part 711 of the second pinching member 72 The cable 19 contacts the inclined portion 721 . In this case, the attitude of the cable 19 is corrected in stages by the first inclined part 711 and the second inclined part 721. Therefore, the label wrapping device 1A can further facilitate the user's operation of arranging the cable 19 at the wrapping position Pm.

The inclined surface 82A of the guide member 8A guides the cable 19 toward the first inclined portion 711 of the first sandwiching member 71. The inclined surface 82A is inclined so that the distance between it and the first inclined part 711 increases as it goes toward the side opposite to the insertion direction S1. In this case, the inclined surface 82A can guide the cable 19 entering the insertion recess 62A toward the first inclined portion 711 of the first sandwiching member 71. Therefore, the label wrapping device 1A can facilitate the user's operation of moving the cable 19 toward the first pinching member 71 and the second pinching member 72 by using the inclined surface 82A.

The first sandwiching member 71 has a guide portion 76 on the first opposing portion 710 . The second sandwiching member 72 has a guiding portion 77 on the second facing portion 720 . The guiding parts 76 and 77 apply a force corresponding to the urging force of the urging part 73 to the cable 19 in the direction toward the winding position Pm. Therefore, the guiding parts 76 and 77 can efficiently apply the biasing force of the biasing part 73 to the cable 19 and guide the cable 19 to the wrapping position Pm.

The label wrapping device 1A has two holding members 7 (holding members 7A and 7B). The holding members 7A and 7B can guide the cable 19 at two positions separated in the longitudinal direction of the cable 19, and can hold the cable 19 at the winding position Pm. Therefore, the label wrapping device 1A uses the holding members 7A and 7B to guide the cable 19 at two positions spaced apart in the longitudinal direction, so that the cable 19 can be easily and stably placed at the wrapping position Pm and held. can.

The detection unit 26 is a contact type displacement sensor. The detection unit 26 includes a movable piece 28 that is displaced by contacting the cable 19 at the winding position Pm, and a switch that detects the displacement of the movable piece 28. Therefore, the label wrapping device 1A can detect that the cable 19 is at the wrapping position Pm with an existing simple configuration.

If only one of the detection units 26A and 26B detects that the cable 19 is at the wrapping position Pm (S51: YES), the label wrapping device 1A notifies that the cable 19 is not attached normally. (S55). Therefore, the user can easily recognize that the cable 19 is arranged in an inclined state with respect to the wrapping position Pm.

The winding mechanism 6 is rotatably supported by the frame 11 about an axis 6A. Further, in a state where the cable 19 is placed at the winding position Pm, the center line C of the cable 19 coincides with the axis 6A. Therefore, even if the wrapping mechanism 6 rotates to wrap the label 10A, the position of the cable 19 does not change. Therefore, the label winding device 1A can suppress the position of the cable 19 from shifting when the winding mechanism 6 winds the label 10A. Therefore, the label wrapping device 1A can wrap the label 10A around the cable 19 without wrinkles, and can improve the wrapping quality of the label 10A.

<Modified example>
The present invention is not limited to the above embodiments, and various modifications are possible. The wrapping mechanism 6 may wrap the label 10A around the cable 19 in a different way than rotating around the cable 19. For example, the label 10A may be wrapped around the cable 19 by rotating the cable 19 with one end of the label 10A attached to the cable 19. The label wrapping device 1A may include a member separate from the holding member 7 that guides the cable 19 to the wrapping position Pm. That is, the holding member 7 may have only the function of holding the cable 19 at the wrapping position Pm. The detection parts 26A and 26B may be provided inside the first bottom part 621 and the second bottom part 622 of the winding mechanism 6. Three or more detection units 26 may be provided in the longitudinal direction of the cable 19, or only one detection unit 26 may be provided. The detection unit 26 may be a sensor that detects the cable 19 using another method. For example, the detection section 26 may be an optical sensor that includes a light emitting section and a light receiving section at a position opposite to the wrapping position Pm.

The holding member 7 may be composed of only one of the holding members 7A and 7B. That is, the holding member 7 may be provided only on the left or right side of the winding mechanism 6. The first clipping member 71 and the second clipping member 72 may each be movable in the front-rear direction. Only one of the first clipping member 71 and the second clipping member 72 may be movable, and the other may be fixed to the frame 11. The positions of the upper end portions of the first pinching member 71 and the second pinching member 72 in the vertical direction may be the same. Alternatively, the upper end of the second clipping member 72 may be disposed higher than the upper end of the first clipping member 71. At least a portion of the first sloped portion 711 of the first clipping member 71 and the second sloped portion 721 of the second clipping member 72 may be arranged at the same position in the vertical direction. The first sloped portion 711 of the first clipping member 71 and the second sloped portion 721 of the second clipping member 72 may each be curved. Instead of the biasing portion 73, a link mechanism may be provided that brings the first pinching member 71 and the second pinching member 72 closer together in response to the cable 19 being placed at the winding position Pm. The holding member 7 may have a recess that is recessed toward the wrapping position Pm. The width of the recessed portion may gradually become smaller as it approaches the wrapping position Pm.

The slope direction of the slope 82A of the guide member 8A may be defined so that the cable 19 is guided toward the gap between the first clip member 71 and the second clip member 72. A plurality of rollers capable of guiding the cable 19 downward may be provided on the inclined surface 82A. A conveyance mechanism (such as a conveyance roller) for conveying the cable 19 toward the first inclined portion 711 of the first sandwiching member 71 may be provided in the guide member 8 . In this case, a series of operations for moving and holding the cable 19 to the wrapping position Pm may be automated.

The guiding portion 76 of the first sandwiching member 71 is composed of only the inclined portion 76A, and may not include the inclined portion 76B. The guiding portion 77 of the second pinching member 72 includes only the inclined portion 77A, and may not include the inclined portion 77B. In this case, the cable 19 may be guided downward by the inclined portions 76A and 76B, and then come into contact with the bottom portion 620A of the winding mechanism 6, thereby restricting its movement and may be held at the winding position Pm.

When the label wrapping device 1A detects that the cable 19 is present at the wrapping position Pm by only one of the detection sections 26A and 26B (S51: YES), the label wrapping device 1A determines the position of the detection section 26 that is not detected (left side or right side). A message indicating this may be displayed on the notification unit 93A to prompt the user to correct the arrangement of the cable 19.

The position of the center line C of the cable 19 disposed at the winding position Pm may be different from the position of the axis 6A corresponding to the rotation center of the winding mechanism 6.

The label wrapping device 1A may include a printing section that can print on the label 10A. The printing unit may print on the label 10A of the label tape 10. The label wrapping device 1A may wrap the label 10A printed by the printing device around the cable 19.
