The downstream end (the other end) moves until it reaches directly below the winding drum 27 of the take-up reel 26. The aforementioned swing frame 33, cylinder 35, rodless cylinder 38, and conveyor 39 as a whole are conveyed while guiding the starting end of the liner 15 unwound from the unwinding roll 13 to the winding drum 27 of the take-up reel 26. The guiding means 32 is configured. Since the guiding means 32 is configured as described above, when the conveyor 39 is retracted to the swing frame 33 until it overlaps vertically, a wide space can be formed in the vicinity of the take-up reel 26. Thus, the winding operation of the liner 15 and the replacement operation of the winding reel 26 can be facilitated.
[0010]

On the other side of the support post 45, a guide rail 46 extending in the vertical direction is laid. 47 is an elevating body that is slidably supported by the guide rail 46, and a pass roller 48 that changes the direction of the liner 15 is rotatably supported by the elevating body 47. 49 and 50 are pulleys rotatably supported by the upper end and the lower end of the support post 45, respectively. Between these pulleys 49 and 50, a belt 51 connected to the elevating body 47 is hung at one place. Has been passed. As a result, when the belt 51 travels, the lifting body 47 and the pass roller 48 move up and down while being guided by the guide rail 46, and this lifting path intersects the traveling path of the liner 15. 52 is a motor attached to the upper end of the support post 45, and a belt 54 is stretched between the pulley 53 and the pulley 49 fixed to the output shaft of the motor 52, whereby the motor When 52 is activated, the belt 51 travels. Reference numeral 55 denotes a lock mechanism attached to the upper end of the support post 45. The lock mechanism 55 has a lock arm 56 whose central portion is rotatably connected to the support post 45.

[0011]
65 is one of the rectangular locking members attached to the inner end side of the liner 15 of the unwinding roll 13 which is fully wound, and 66 is the entire outer periphery of the winding drum 27 of the take-up reel 26. It is the other locking body which is attached over the above and constitutes the locking means 67 with the one locking body 65. Here, as one locking body 65, for example, either the male or female side fastener of the planar fastener can be used, and the other of these can be used as the other locking body 66. It is preferable to use one of a thin plate-like ferromagnetic sheet and a thin plate-like magnet sheet as the locking body 65 and the other of them as the other locking body 66. The reason is that both the locking members 65 and 66 can be made thin to the extent that they do not affect the winding, can prevent the generation of fine fragments, and can be used repeatedly for a long time. Because. In the above-described case, it is more preferable that the ferromagnetic sheet is one locking body 65 and the magnet sheet is the other locking body 66. The reason is that the magnet sheet is less susceptible to bending and more susceptible to cracking than the ferromagnetic sheet, so the magnet sheet should not be subjected to repeated bending and should be provided on the winding drum 27 having a large bending radius of curvature. This is because it is advantageous in strength. Here, as the ferromagnetic body, steel, nickel, cobalt, or an alloy of the above-described ones, for example, stainless steel can be used, and both the locking bodies 65 and 66 are attached to the liner 15 and the winding drum 27. For example, an adhesive can be used. The other locking body 66 may be attached by being embedded in the winding drum 27.
[0012]
Next, the operation of one embodiment of the present invention will be described.
In order to unwind the liner 15 from the unwinding roll 13 and wind it onto the take-up reel 26, first, the full-winding unwind roll 13 and the empty take-up reel 26 are loaded and mounted on the support frames 12 and 25, respectively. However, one locking member 65 is attached to the inner surface side start end of the liner 15 of the unwinding roll 13, and the other locking member 66 is attached to the winding drum 27 of the take-up reel 26. At this time, the conveyor 39 is retracted to one end and overlaps with the swing frame 33, and the lifting body 47 and the pass roller 48 are lowered to the lower limit and stand by, and the detection roller 18 is separated from the unwinding roll 13. .
[0013]
In this state, the unwinding roll 13 is rotated by the drive mechanism, and the liner 15 is unwound from the unwinding roll 13. At this time, the liner 15 unwound from the unwinding roll 13 hangs down from the unwinding roll 13. . Simultaneously with the unwinding, the conveyor 39 is operated to run the conveyor 39 toward the other side. When the unrolled liner 15 falls on the running conveyor 39, the liner 15 is moved by the conveyor 39. It is conveyed toward the other side (the take-up reel 26). When the start end of the liner 15 reaches the downstream end of the conveyor 39 (the other end close to the take-up reel 26) and the start end is detected by a photoelectric sensor (not shown), the conveyance of the liner 15 is stopped. In addition, the rodless cylinder 38 is operated to move the conveyor 39 along the guide rail 37 to the other side (toward the take-up reel 26). At this time, the rotational speed (unwinding speed) of the unwinding roll 13 and the moving speed of the conveyor 39 are controlled so that the position of the starting end of the liner 15 with respect to the conveyor 39 does not change. The movement of the conveyor 39 is stopped when the downstream end portion of the conveyor 39, in other words, the start end portion of the liner 15 is conveyed to just below the winding drum 27.
[0014]
Next, the piston rod 36 of the cylinder 35 is retracted, and the swing frame 33 and the conveyor 39 are integrally swung around the hinge 34 so that the other end (downstream end) of the conveyor 39 rises. As a result, the start end portion of the liner 15 approaches the winding drum 27, and the one locking member 65 attached to the starting end portion of the liner 15 is the other locking member 66 attached to the outer periphery of the winding drum 27. For example, it is locked by suction, and the starting end portion of the liner 15 is fixed to the winding drum 27 of the take-up reel 26. Thus the starting end of the liner 15 without troubling the operator's hand can be easily and reliably fastened to the winding drum 27, labor saving is Ru is achieved.
[0015]
Next, the piston rod 36 of the cylinder 35 is projected to swing the swing frame 33 and the conveyor 39 to the initial substantially horizontal position, and then the rodless cylinder 38 is operated to move the conveyor 39 to the swing frame 33. Move one side to the overlapping initial position. Thereafter, the motor 52 is operated to cause the belts 54 and 51 to travel, and the elevating body 47 and the pass roller 48 are raised along the guide rail 46. In the middle of this rise, the pass roller 48 contacts the liner 15 that bridges between the unwinding roll 13 and the take-up reel 26, so that a part of the liner 15 is pulled up by the pass roller 48 and bent into an inverted V shape. . At this time, the liner 15 is unwound from the unwinding roll 13 so that the starting end portion of the liner 15 does not come off from the winding drum 27. When the elevating body 47 and the pass roller 48 reach the ascending limit, the piston rod 58 of the cylinder 57 protrudes, the lock arm 56 swings, and the engagement recess 59 is engaged with the elevating body 47. Thereby, the elevating body 47 and the pass roller 48 are locked to the ascending limit. Only in this manner increases the path rollers 48, after contacting one after another to pass rollers 61,60,48 can easily form formed the pass line of the liner 15 leading to the winding drum 27 of the take-up reel 26. Next, the piston rod 20 of the cylinder 19 is protruded, and the arm 17 is swung until the detection roller 18 is brought into rolling contact with the outer periphery of the liner 15 of the unwinding roll 13, and the unwinding roll 13 and the take-up reel are driven by the drive mechanism. Both are rotated several times, and the liner 15 is wound around the winding drum 27 several times.
[0016]
Next, the unwinding roll 13 and the take-up reel 26 are rotated together by the drive mechanism to cause the liner 15 to travel along the aforementioned pass line, and the supply conveyor 28 is operated to move the belt-like member 29 downstream of the supply conveyor 28. It is fed between the liner 15 just before being wound from the end (one side end) and the winding drum 27, and the liner 15 and the belt-like member 29 are wound around the winding drum 27 one after another in a state where they are overlapped. At this time, the detection roller 18 detects the unwinding speed of the liner 15 and detects the feeding speed of the belt-like member 29 by a detection sensor (not shown). Based on the detection results of the detection roller 18 and the detection sensor The rotational speed of the take-up reel 26 is controlled.
[0017]
When all the belt-like members 29 to be taken up are taken up on the take-up reel 26 in this way, the liner 15 remaining on the take-up roll 13 is taken up on the take-up reel 26. Next, the cylinder 57 is operated to release the lifting body 47 and the pass roller 48 from being locked by the lock arm 56, and then the motor 52 is operated to move the lifting body 47 and the pass roller 48 to the lower limit, and the piston of the cylinder 19 The detection roller 18 is separated from the reel 14 by retracting the rod 20. Thereafter, the reel 14, the liner 15, and the take-up reel 26 on which the belt-like member 29 is taken up are removed from the support frames 12 and 25 and carried to the next process. The above is one cycle of the operation of this embodiment, and this cycle is repeated thereafter.
[0018]
In the above-described embodiment, both the unwinding roll 13 and the take-up reel 26 are rotated by the driving mechanism when the liner 15 is taken up on the take-up reel 26. The take-out roll may be freely rotated, and the take-up reel may be rotated by a drive mechanism.
[0019]
