  Next, a method for connecting the old and new long bodies RS2 and RS1 by the long body connecting apparatus 10 will be described.

  First, while the old elongated body RS1 is fed from the old elongated body support means 13 via the unillustrated feeding means, the sticking means 25 drives the linear motion motors 68 and 69, and the sliders 68A and 69A are moved forward or backward. Move. After that, when an operator or an adhesive sheet supply device (not shown) supplies the connection adhesive sheet SS, the sticking means 25 drives the suction means (not shown) and holds the connection adhesive sheet SS by the sliders 68A and 69A. The linear motion motors 68 and 69 are driven, and the sliders 68A and 69A are positioned on both the upper and lower sides of the old long body RS1. Further, the operator pulls out the lead end side of the new long body RS2 and arranges the lead end side between the gripping members 65A (see FIG. 1). Thereafter, the overlapping region forming means 23 drives the chuck cylinder 65 and holds the lead end side of the new long body RS2 by the gripping member 65A.

  Then, when the old long body RS1 is fed out, if the decrease of the old long body RS1 or the final end of the old long body RS1 is detected by a detection means (not shown), the feeding of the old long body RS1 is performed. Stop. Next, the overlapping region forming means 23 drives the linear motor 66 to pass the gripping member 65A holding the lead end side of the new long body RS2 from the left side to the right side of the passage ST. Then, the guide means 15 drives the linear motor 33 to lower the guide roller 31 so that the new long body RS2 is positioned substantially parallel to the old long body RS1 (see the two-dot chain line in FIG. 1). Thereafter, the first and second restricting means 21 and 22 drive the linear motion motors 59, 60, 59 ′, and 60 ′, and the first and second adsorbing portions 57, 58, 57 ′, and 58 ′ cause the old and new long bodies. RS2 and RS1 are sandwiched and held. Thereby, new long body RS2 is overlaid on the upper surface side of old long body RS1, and those overlap area | region WA is formed (refer FIG. 2). At this time, the 1st and 2nd control means 21 and 22 drive an adsorption | suction means, and adsorb | suck with respect to the elongate body RS1 and RS2 which contact | connect the 1st and 2nd adsorption | suction part 57,58,57 ', 58'. . Even after the overlapping area WA is formed, the lead end side of the new elongated body RS2 remains held by the gripping member 65A.

  After forming the overlap area WA, the cutting means 17 drives the linear motion motor 38 and lowers the cutting blade 36. At the same time, the receiving means 18 drives the linear motion motor 49 and raises the receiving member 48. Before and after this, the cutting means 17 and the receiving means 18 drive the suction means. Thereby, the overlapping area WA in the vicinity of both the left and right sides of the cutting blade 36 is sandwiched while the old and new long bodies RS2 and RS1 are sucked and held by the pressing member 42 and the receiving member 48, and the tip of the cutting blade 36 is placed in the groove 48A. Inserted. Then, the cutting means 17 drives the linear motor 37 to move the cutting blade 36 from the rear end side of the old and new long bodies RS2, RS1 to the front end side or from the front end side to the rear end side. Thereby, the old and new long bodies RS2 and RS1 are cut in the overlapping area WA in the front-rear direction, which is a direction intersecting the extending direction, and the terminal edge RS1r and the unnecessary old length are added to the old long body RS1 at this cutting position. The scale portion RS1D is formed, and the leading edge RS2f and the unnecessary new length portion RS2D are formed on the new long body RS2 (see FIG. 3).

  After cutting the old and new long bodies RS2, RS1, the cutting means 17 stops driving the suction means, and then drives the linear motor 38 to raise the cutting blade 36, and the second regulating means 22 is the linear motor. 59 'is driven, 1st adsorption | suction part 57' is raised, and unnecessary new elongate body part RS2D and old elongate body RS1 are spaced apart. After this separation, the overlapping region forming means 23 drives the linear motor 66, moves the gripping member 65A to the right, and separates the distal end edge RS2f from the unnecessary new elongated body portion RS2D. The separated unnecessary new long body portion RS2D is removed by a driving device or the like (not shown), and the end edge RS1r of the old long body RS1 and the front end edge RS2f of the new long body RS2 are abutted in plan view. In addition, while removing unnecessary new elongate body part RS2D, terminal edge RS1r area | region of old elongate body RS1 is 2nd adsorption | suction part 58 'of the 2nd control means 22 as a termination | terminus area holding | maintenance part, and the receiving member 48. Therefore, there is no inconvenience that the terminal edge RS1r moves.

  After the end edge RS1r and the front edge RS2f are abutted, the cutting means 17 drives the rotation motor 43 to rotate the L-shaped arm 41 so that the slider 68A and the connection adhesive sheet SS held on the slider 68A face downward. To do. After that, the cutting means 17 drives the linear motion motor 38 and lowers the slider 68A to press and attach it to the upper region straddling the terminal edge RS1r and the tip edge RS2f with which the connecting adhesive sheet SS is abutted (see FIG. 4). ).

  After this sticking, the receiving means 18 stops driving the suction means and then drives the linear motor 49. After lowering the receiving member 48, the rotating motor 52 is driven to rotate the L-shaped arm 51, The slider 69A and the connection adhesive sheet SS held by the slider 69A are set upward. In addition, after the receiving member 48 is lowered, the first regulating means 21 drives the linear motor 60 to lower the unnecessary old long body portion RS1D that is sucked and held by the second sucking portion 58, and the new long body RS2. Separate. The separated unnecessary old long body portion RS1D is removed by a driving device (not shown) or the like. In addition, while removing unnecessary old elongate body part RS1D, the front-end | tip edge RS2f area | region of new elongate body RS2 and the 1st adsorption | suction part 57 of the 1st control means 21 as a front-end | tip area | region holding | maintenance part, and connection adhesive sheet SS Therefore, there is no inconvenience that the tip edge RS2f moves by being attracted and held by the slider 68A.

  After removing the unnecessary old long body portion RS1D, the receiving means 18 drives the linear motion motor 49 to raise the slider 69A, and the lower region straddling the end edge RS1r and the end edge RS2f that are brought into contact with the connecting adhesive sheet SS To make it stick (see FIG. 5). As a result, the connection adhesive sheets SS are attached to both the upper and lower sides of the terminal edge RS1r and the tip edge RS2f, and the old and new long bodies RS2, RS1 are connected by the connection adhesive sheet SS. Then, after the first and second regulating means 21 and 22 and the sticking means 25 stop driving the suction means and release the suction holding of the suction portions 57 and 58 ′ and the sliders 68A and 69A, the guide means 15 and the cutting The means 17, the receiving means 18, the first and second restricting means 21, 22 drive the linear motion motors 32, 38, 49, 59, 60 ', the guide rollers 30, the sliders 68A, 69A, and the suction portions 57, 58'. Is separated from the old and new long bodies RS2, RS1. By driving the feeding means (not shown) in this state, the new long body RS2 can be fed out continuously from the old long body RS1.

  Thereafter, the new long body support means 14 and the new long body RS2 are sequentially fed out as the old long body support means and the old long body. Further, the old long body support means 13 from which the unnecessary old long body portion RS1D has been removed becomes a new long body support means, and the next long body is supported as a new long body by the operator, and the lead end After the side is gripped by the gripping member 63A, the linear motor 64 is driven to pass the lead end side from the left side to the right side of the passage ST, and the above operation is repeated thereafter. In this case, the end region holding portion described above is configured by the first suction portion 57 ′ of the second restricting means 22, and the tip region holding portion is configured by the second suction portion 58 of the first restricting means 21.

  Therefore, according to such an embodiment, by moving the gripping members 65A and 63A by the linear motors 66 and 64, the lead end side of the new elongated body RS2 can be passed through the passage ST, and is unnecessary after the passage. Until the new long body portion RS2D is removed, the lead end side of the new long body RS2 can be held by the gripping members 65A and 63A. As a result, it is not necessary to separately provide a means for passing the passage ST and a means for holding the new elongated body RS2 after passing, and it is possible to avoid an increase in the size of the apparatus and a complicated configuration.
