BACKGROUND OF THE INVENTION
This invention relates to Shi equipment unwinding unwinding by switching a reel winding the belt-shaped member with the liner.
[0002]
[Prior art]
Conventionally, the switching unwinding of the belt-shaped member includes, for example, a separation roll that individually separates the belt-shaped member and the liner that are overlapped with each other, a winding roll that winds the liner separated from the belt-shaped member by the separation roll, and a separation roll An unwinding station immediately before a fixed frame to which a feed roll for feeding a strip-shaped member separated from the liner by a roll and a servicer for supplying the strip-shaped member fed from the feed roll to the forming drum while forming a festoon are attached. In addition, the reel having the belt-shaped member wound with the liner a number of times is conveyed from the storage station to the unwinding station by a low lift and is rotatably supported by the support base.
[0003]
Next, the liner is manually guided to the take-up roll through the separation roll while unwinding from the reel, and then the take-up roll is rotated, and the liner is wound until the beginning of the belt-like member appears (cues). Take up the roll. Next, the feeding roll and the take-up roll are rotated to unwind the belt-like member and the liner from the reel. At this time, the belt-like member and the liner are individually separated by the separating roll, and the belt-like member is formed to form a festoon. While sending it out to the servicer, the liner is wound on a winding roll. At this time, the belt-shaped member fed to the servicer is supplied to the forming drum while being cut into a predetermined length, and is wound around the periphery thereof.
[0004]
When the type of the belt-like member wound around the forming drum is changed, the belt-like member is cut with a knife in the festoon, and then the reel is reversely rotated to rewind the belt-like member and the liner onto the reel. Here, since the liner is used repeatedly, it cannot be cut. Therefore, it is necessary to rewind all the liners wound on the winding roll onto the reel.
[0005]
Thereafter, the reel is removed from the support and transported to the storage station by a low lift, and the reel on which the next strip member to be unwound is wound is transported from the storage station to the unwind station by a low lift. Switching and unwinding.
[0006]
[Problems to be solved by the invention]
However, in the switching unwinding Shi equipment of such a conventional strip, each time the belt-shaped member switch, the unwinding station, a liner take-up for cueing strip, and unwinding However, there is a problem in that the work efficiency is lowered because the winding operation on the forming drum must be stopped during such work.
[0007]
This invention aims at providing a Shi output switching winding of the belt-shaped member which can improve the working efficiency by reducing downtime of the forming drum at the time of switching of the belt-shaped member equipment.
[0008]
[Means for Solving the Problems]
Such object is achieved by a movable frame for rotatably supporting the reel are belt-like member taken many times wound with the liner, provided to the movable frame individually separated strip and liner unwound from the reel Separating means, a winding roll that is rotatably supported by the movable frame and that winds the liner separated from the belt-like member by the separating means, and is rotatably supported by the movable frame and separated from the liner by the separating means. A feeding roll for feeding the strip-shaped member toward the downstream side,
At the standby station away from the unwinding station, the reel is rotated to rewind the liner, and the belt-shaped member is cueed. When the movable frame is transferred from the standby station to the unwinding station, the take-up roll and the feed The roll is rotated to unwind the belt-like member and liner from the reel, and these are separated by the separating means so that the liner is wound on the take-up roll and the belt-like member is sent downstream, while the reel is movable. In the switching and unwinding device for the belt-shaped member that can be exchanged for the frame,
The reel is composed of a pair of disc-shaped flanges, and a cylindrical winding drum that connects the flanges and protrudes from the flanges at both ends. Three pairs of support rollers for supporting at three points are provided to support the rotation of the reel, and among the support rollers, a pair of support rollers located on one side can be retracted from the reel loading / unloading path. More can be achieved.
[0009]
First, in the standby station, by rotating the feed roll and the take-up roll, the belt-shaped member and the liner are unwound from the reel so that the starting end of the belt-shaped member appears (performs cueing) and the cueing is performed. The liner is rolled up on the winding roll. Next, the belt-shaped member, the reel on which the liner is wound, and the movable frame are transferred from the standby station to the unwinding station. Next, the take-up roll and the feed roll are rotated to unwind the belt-like member and liner from the reel, and these are separated by a separating means, and the liner is wound on the take-up roll, and the belt-like member is fed by the feed roll. Deliver downstream.
[0010]
Next, for example, when the type of the belt-shaped member to be unwound is changed, after the unwinding of the belt-shaped member is finished, the movable frame is transferred from the unwinding station to the standby station. Thereafter, at the standby station, the reel is rotated to rewind the long liner onto the reel. Here, corresponding to the type change of the belt-shaped member in the state that still remains strip the reel, the belt-shaped member, for example, by cutting the festoon, but to transfer the movable frame to the waiting station, the waiting station In this case, the liner need not be rewound onto the reel. However, if necessary, the liner may be rewound onto the reel at the unwinding station or the standby station to such an extent that the belt-like member is hidden.
[0011]
In this way, at the standby station away from the unwinding station, the liner winding for cueing the belt-like member as the outer setup and the rewinding operation to the reel of the long liner are performed, or the reel to the liner is performed. Thus, the belt-shaped member can be unwound immediately after the movable frame is transferred to the unwinding station, and the reel is wound together with the movable frame immediately after the strip-shaped member is unwound. The next reel and the movable frame can be carried into the unwinding station after unloading from the unloading station. As a result, the stop time of the apparatus at the time of switching the belt-like member is shortened, and the work efficiency can be improved.
[0012]
Further, it is possible to reduce the required number of the variable dynamic frame, while made reliable rolling support of Li Lumpur, loading and unloading of the reel with respect to the movable frame can be facilitated.
Furthermore, if it comprises as described in Claim 2 , the carrying in / out operation | work of a reel will become still easier.

[0028]
Next, the operation of one embodiment of the present invention will be described.
Assume that the movable frame 14 that supports the reel 17 of the belt-like member B that performs unwinding is waiting at the standby station T. At this time, in the standby station T, the operator pulls out the liner R from the reel 17 and hangs around the guide roller 53, the separation roll 51, and the guide roller 52 one after another, and then the start end is fixed to the winding roll 56. .
[0029]
Next, the drive motor 60 is operated with the clutch connected, and the take-up roll 56 and the feed roll 57 are rotated. As a result, the liner R is taken up and the reel 17 rotates. At this time, the liner R is wound around the winding roll 56 one after another. In this way, when the entire portion of the liner R alone is wound on the winding roll 56, the strip member B and the liner R are unwound from the reel 17 while being overlapped with each other, and the strip member B appears. Then, when the starting end of the belt-like member B is unwound to the vicinity of the feed roll 57, the belt-like member B is cueed. At this time, the operation of the drive motor 60 is stopped.
[0030]
In this way, when the belt-like member B is being cued at the standby station T, at the unwinding station M, the drive motor 60 is operated with the clutch connected, and the winding roll 56 and the feeding roll 57 are moved. Rotate. As a result, the belt-like member B and the liner R that overlap each other are unwound from the reel 17, and the belt-like member B and the liner R are individually separated by the separation roll 51. Then, one liner R is wound around the winding roll 56, and the other belt-like member B is fed to the downstream side, that is, the servicer 11 by the feeding roll 57 while forming the festoon 58. The belt-like member B sent out to the servicer 11 in this way is then supplied to a molding drum (not shown) while being cut to a predetermined length, and is wound around the periphery thereof.
[0031]
Next, when the belt-like member B is completely unwound from the reel 17 and the type of the belt-like member B is changed, the operation of the drive motor 60 in the unwinding station M is stopped to wind the belt-like member B. After the unloading is finished, a low lift fork is inserted into the insertion portion 15, and then the movable frame 14 is lifted by the fork, and the reel 17 and the movable frame 14 in the above-described state are unloaded from the unwinding station M to the standby station T. Transport. On the other hand, the movable frame 14 that has been waiting at the standby station T in the state where the head has been positioned is transferred from the standby station T to the unwinding station M by a low lift in the same manner as described above.
[0032]
Next, in the unwinding station M, the start end of the band-shaped member B that has been cued is joined to the terminal end of the band-shaped member B waiting on the servicer 11, and then the drive motor 60 is operated to operate the winding roll 56. Then, the feeding roll 57 is rotated, and the belt-like member B and the liner R unwound from the reel 17 are individually separated and sent to the servicer 11 and wound on the take-up roll 56.
[0033]
On the other hand, at the standby station T, the piston rod 48 of the cylinder 47 is protruded, and the swing arm 38 is swung downward until the drive roller 44 is pressed against the protrusion 20 of the reel 17. Next, the clutch of the drive motor 60 is released to allow the winding roll 56 and the delivery roll 57 to rotate freely, and then the drive motor 39 is operated to rotate the drive roller 44. At this time, the rotation of the drive roller 44 is transmitted to the protruding portion 20 of the reel 17 by friction, and the reel 17 is rotated in the direction opposite to that at the time of unwinding. As a result, all of the long liner R unwound from the reel 17 and wound on the take-up roll 56 is rewound onto the reel 17. Next, the piston rod 48 of the cylinder 47 is retracted to separate the drive roller 44 from the reel 17, and the clutch of the drive motor 60 is connected.
[0034]
Further, when changing the type of the belt-like member B in a state where the belt-like member B still remains on the reel 17, after the unwinding of the belt-like member B is finished in the same manner as described above, the belt-like member B is moved in the festoon 58. Cut in the width direction with a knife. Next, while the reel 17 and the movable frame 14 in the above-described state are transferred from the unwinding station M to the standby station T, the movable frame 14 whose head has been positioned is transferred from the standby station T to the unwinding station M. . At this time, the liner R does not necessarily have to be rewound onto the reel 17 at the standby station T, but the liner R is unwound at the unwinding station M or the standby station T to such an extent that the short strip member B being unwound is hidden as necessary. The reel 17 may be rewound in the same manner as described above.
[0035]
In addition, when there is no reel 17 on which the belt member B of the type to be unwound next is wound at this standby station T, the cylinder 27 of one of the movable frames 14 is operated to move the piston rod 28. Retract and swing the swing link 29 to the position indicated by the phantom line to retract the swing link 29 and the support roller 32 from the carry-in / out path of the reel 17 and rotate the support roller 32 from the rear side of the reel 17 End support.
[0036]
Next, the reel 17 is moved toward the rear side while rolling on the floor surface, and is carried out of the movable frame 14. At this time, since the protruding portion 20 of the reel 17 is guided by the rail 35, the reel 17 The unloading work becomes easy. Thereafter, the reel 17 around which the belt-shaped member B of the type to be unwound next is wound is carried into the movable frame 14 from the rear side, and the protruding portion 20 of the reel 17 is also guided by the rail 35 at this time. The carrying-in work of the reel 17 becomes easy. Next, the piston rod 28 of the cylinder 27 is protruded, and the swing link 29 is swung downward until the support roller 32 contacts the protrusion 20 of the reel 17, and the reel 17 is rotated from the rear side by the support roller 32. To support.
[0037]
In this way, in the standby station T away from the unwinding station M, in addition to winding the liner R for cueing the belt-like member B as an external setup, and rewinding the liner R to the reel 17 as necessary. Since the reel 17 is exchanged, the belt-like member B can be unwound immediately after the movable frame 14 is transferred to the unwinding station M, and immediately after the unwinding of the belt-like member B is completed. The reel 17 can be carried out together with the movable frame 14 from the unwinding station M, and the next reel 17 and movable frame 14 can be carried into the unwinding station M. As a result, the stop time of the apparatus such as the forming drum at the time of switching the belt-like member B is shortened, and the work efficiency can be improved. Such switching is the same when the reel 17 becomes empty and is replaced with a full reel 17.
[0038]
In the above-described embodiment, the movable frame 14 is provided with the reel drive mechanism 49 that drives the reel 17, the take-up roll 56, and the drive motor 60 that drives the feed roll 57. However, in the present invention, the reel The drive mechanism and winding mechanism that drives the drive roll and the drive mechanism that drives the delivery roll are installed in the standby station and the unwind station, respectively.When the movable frame is transferred to each station, these drive mechanisms are reeled, wound, A driving force may be applied by being connected to a delivery roll.
[0039]
