Therefore, when the new long body is drawn out and the next long body is joined to the terminal edge of the new long body, the new long body becomes the old long body, and the next long body becomes the new long body. Become.

  1 and 2, the long body positioning device 10 matches the extending directions (left and right directions) of the strip-like old long body RS1 positioned below and the strip-shaped new long body RS2 positioned above. In such a state, the overlapping areas WA are formed by overlapping those partial areas, and the old and new elongated bodies RS2 and RS1 are cut in the overlapping area WA, thereby forming the terminal edge RS1r in the old elongated body RS1. At the same time, a front edge RS2f is formed on the new elongated body RS2, and the terminal edge RS1r and the front edge RS2f are provided so as to be able to abut each other. The long body positioning device 10 feeds out the old long body RS1 wound in a roll shape and the guide means 11 that can be arranged on one surface (lower surface) side of the old and new long bodies RS2 and RS1 in the overlapping area WA. An old elongate body support means 13 composed of a support shaft that can be supported, a new elongate body support means 14 composed of a support shaft that supports the new elongate body RS2 wound in a roll shape, and a guide means. 11 is disposed on the upstream side (left side) and the downstream side (right side) of the long and long body cutting device 15 in the extending direction of the old and new long bodies RS2 and RS1. A pair of first and second regulating means 17 and 18 capable of regulating the movement of the old and new long bodies S1 and RS2 by sandwiching the old and new long bodies S1 and RS2 between the means 11 and each other.

  The guide means 11 is formed with a groove 11A extending in the front-rear direction and positioning holes 11B provided at four locations on the upper surface thereof. The guide means 11 is made of magnetizable iron, an electromagnet, a permanent magnet, or a material including them, or a member in which they are partially incorporated.

  The old elongate body support means 13 and the new elongate body support means 14 are supported by an arm AM that can be rotated by a rotation motor DM1 as a drive device.

  The long body cutting device 15 includes a holding means 21 capable of holding the old and new long bodies RS2, RS1 by sandwiching the old and new long bodies RS2, RS1 with the guide means 11 in the overlapping area WA, and the holding means 21. A cutting blade 22 as cutting means capable of cutting the old and new long bodies RS2 and RS1 held in the overlapping area WA, and a holding means 21, and a direction crossing the extending direction of the long bodies RS1 and RS2 ( By the moving means 23 capable of moving the cutting blade 22 in the front-rear direction, the inserting / extracting means 25 provided on the moving means 23, and capable of inserting and extracting the cutting blade 22 into and out of the old and new long bodies RS2, RS1. And an adjusting means 26 capable of adjusting the amount of insertion of the cutting blade 22.

  The holding means 21 is embedded in a pressing member 28 having a substantially concave shape in front view in which a slit 27 having a substantially same planar shape as the groove 11A of the guiding means 11 is formed in a plan view, and embedded in the lower surface side of the pressing member 28. 11 that sticks to iron 11, an electromagnet, a permanent magnet, or a material including them, or a magnetizing means 29 as an adhering means made of a member in which they are partially incorporated, and protrudes from the lower surface of the pressing member 28. , Positioning pins 32 as positioning means that can be fitted in the positioning holes 11B of the guide means 11, and handles 33 provided on both front and rear sides of the pressing member 28, respectively.

  The moving means 23 includes a pair of rails 37 provided along the slits 27 on the pressing member 28, and a slider 38 provided so as to be movable along the rails 37. The slider 38 is urged or temporarily fixed at a position indicated by a solid line on the left side in FIG. 2 by an urging means such as a spring or rubber (not shown), a magnet, a lock mechanism, or the like.

  The insertion / extraction means 25 is supported on each slider 38 and has a lower plate 40 provided with a through hole 40A through which the cutting blade 22 can pass, a pair of left and right shaft members 41 erected on the lower plate 40, An upper plate 42 that is slidably supported by the shaft member 41, an elastic member 44 that is provided around each shaft member 41 and includes a coil spring that urges the upper plate 42 upward, and any of the shaft members 41 The stopper 45 is provided so as to be fixed by a set screw (not shown) at the position and suppresses the rising of the upper plate 42, and the bracket 46 is provided on the lower surface of the upper plate 42 and supports the cutting blade 22. Accordingly, when the upper plate 42 is pushed down against the urging force of the elastic member 44, the cutting blade 22 projects from the lower surface side of the pressing member 28 through the slit 27. Therefore, the cutting blade 22 can be protruded from the holding member 28 only at the time of cutting, and the cutting blade 22 can be prevented from protruding from the pressing member 28 at other times. It becomes possible to reliably prevent the old and new long bodies RS2 and RS1 from being damaged by touching RS2 and RS1 and the worker, and the operator from being injured.

  The adjusting means 26 includes an adjuster 48 including a screw portion 48B screwed to the upper plate 42 and a knob portion 48A positioned on the upper portion 42, and an adjuster 48 screwed to the screw portion 48B and pressed against the upper plate 42. And a stopper 49 capable of suppressing the vertical movement of the. As a result, the lower end of the adjuster 48 comes into contact with the lower plate 40 when the upper plate 42 is pushed down. Therefore, the amount by which the cutting blade 22 protrudes from the presser member 28 is adjusted by moving the adjuster 48 up and down. Can do. Therefore, even if it changes to various cutting blades 22 of different sizes (particularly different in vertical length), the amount of insertion of the cutting blade 22 into the old and new long bodies RS2, RS1 is insufficient, or the groove 11A of the guide means 11 It is possible to prevent the bottom from touching the bottom. Further, if the cutting is repeated at the same location of the cutting blade 22, only one portion of the cutting blade 22 is deteriorated and the bending phenomenon is likely to occur. Therefore, the adjuster 48 is moved up and down periodically to cut the cutting blade 22. It is better to cut at another position.

  The first and second regulating means 17, 18 are linear motion motors 51, 52 as drive devices provided inside the guide means 11, and sandwiched so as to be movable up and down by the linear motion motors 51, 52. Members 53 and 54.

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

  As shown in FIG. 1 (A), the remaining amount of the old elongate body RS1 supported by the elongate body support means 13 positioned below is detected by visual detection by a detection means and an operator not shown. Then, the feeding of the old long body RS1 is stopped. Next, the new long body RS2 is pulled out from the new long body support means 14, and the new long body RS2 is passed between the old long body RS1 located on the guide means 11 and the holding members 53, 54, and overlapped. Region WA is formed. Next, the first and second restricting means 17 and 18 drive the linear motion motors 51 and 52, and the old and new long bodies RS2 and RS1 are sandwiched between the guide means 11 and the sandwiching members 53 and 54. Thereafter, the operator grasps the handle 33 of the elongated body cutting device 15 at an arbitrary position indicated by a two-dot chain line in FIG. 2 and cuts the elongated body so that the positioning pin 32 enters the positioning hole 11B. The device 15 is placed on the guide means 11. The elongated body cutting device 15 placed on the guide means 11 is magnetically attached to the guide means 11 with the old and new elongated bodies RS2 and RS1 sandwiched therebetween by the action of the magnetic attachment means 29. As a result, the elongated body cutting device 15 and the guide unit 11 are positioned, and the slit 27 of the holding unit 21 is overlapped with the groove 11A of the guide unit 11 in plan view.

  Thereafter, as shown in FIG. 2, the operator holds the knob 48A and pushes down the cutting blade 22, and the slider 38 is moved along the rail 37 while the lower end thereof is positioned in the groove 11A. Move in the middle right direction. As a result, 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 a terminal edge RS1r is formed on the right side of the cut portion in the old long body RS1. In addition, an unnecessary old long body portion RS1D is formed on the left side of the cutting portion, a tip edge RS2f is formed on the left side of the cutting portion in the new long body RS2, and an unnecessary new long body portion RS2D is formed on the right side of the cutting portion. Is formed. At this time, since the cutting start position (left edge position in FIG. 2) in the old and new long bodies RS2 and RS1 is sandwiched from above and below by the pressing member 28 and the guide means 11, the tension around the cutting start position is insufficient. The bending phenomenon due to the urging of the cutting blade 22 does not occur. In order to prevent the bending phenomenon, the width in the left-right direction of the slit 27 and the groove 11 </ b> A may be as close as possible to the width in the left-right direction of the cutting blade 22. Further, the force in the direction in which the guide means 11 and the long body cutting device 15 approach each other, in the case of this embodiment, it is preferable to increase the magnetizing force. Thereafter, the upper plate 42 and the cutting blade 22 are raised by the elastic force of the elastic member 44 by releasing the force that pushes down the knob 48A.

  After cutting the old and new long bodies RS2 and RS1, the operator holds the handle 33 and removes the long body cutting device 15 from the guide means 11. At this time, when the magnetizing means 29 is an electromagnet, the supply of power is stopped. When the magnetizing means 29 is a permanent magnet, the long body cutting device 15 is moved to the guide means after the permanent magnet is moved away from the guide means 11. If it removes from 11, it can remove easily. When the long body cutting device 15 is removed from the guide means 11, the movement of the old and new long bodies RS <b> 2 and RS <b> 1 is restricted by the first and second restriction means 17 and 18. In this state, the operator lifts up the new long body RS2 and the unnecessary old long body portion RS1D from the first restricting means 17 to the cut portion, and as shown in FIG. The connecting tape CP is stuck downward so as to protrude from the leading edge RS2f. Next, the operator lifts the old long body RS1 and the unnecessary new long body part RS2D from the second restricting means 18 to the cut portion, and the new long body RS2 and the unnecessary old long body to which the connecting tape CP is attached. After the portion RS1D is first placed on the guide means 11, the old long body RS1 and the unnecessary new long body portion RS2D from the second restricting means 18 to the cut portion are placed on the guide means 11. Thus, the leading edge RS2f of the new long body RS2 and the terminal edge RS1r of the old long body RS1 are joined to each other by the joining tape CP from the lower surface side. Thereafter, the operator lifts the unnecessary new long body portion RS2D and puts a connecting tape (not shown) on the leading edge RS2f region of the new long body RS2 and the terminal edge RS1r region of the old long body RS1 so as to straddle the cut portion. Affix to the top. Thus, since the movements of the old and new long bodies RS2 and RS1 are restricted by the first and second restricting means 17 and 18, the tip edge RS2f and the terminal end are in the process of connecting them. The relative position (butting position) with respect to the edge RS1r is not shifted. Then, the first and second regulating means 17 and 18 drive the linear motion motors 51 and 52 to release the old and new long bodies RS2 and RS1 between the guide means 11 and the holding members 53 and 54, and the operator The unnecessary old long body portion RS1D (including the portion supported by the old long body support means 13) and the unnecessary new long body portion RS2D are removed from the guide means 11. Thereafter, by driving the rotation motor DM1, the new long body support means 14 is positioned below, and the new long body support means 14 and the new long body RS2 are connected to the old long body support means and the old long body. It will be fed out sequentially. Further, the old long body support means 13 positioned above by the drive of the rotation motor DM1 becomes a new long body support means, and the next long body is supported as a new long body by the operator. Will be repeated.

  Therefore, according to such an embodiment, since the holding means 21 and the guide means 11 hold the overlapping area WA of the old and new long bodies RS2 and RS1 with each other, the cutting blade 22 is attached around the cutting start position. It is possible to suppress the occurrence of the bending phenomenon due to the force as much as possible. As a result, the cutting failure of the old and new long bodies RS2 and RS1 due to the bending phenomenon can be prevented as much as possible. In addition, since it is physically impossible for the operator to press and pick the vicinity of the cutting start position with a finger, safety for the operator can be ensured.
