Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a core supply device for winding a winder, and relates to a core supply device for automatically supplying a winder with a core to be used when winding paper cut into a predetermined width by a winder. is there.
[0002]
[Prior art]
Conventionally, in order to supply a core to a winder, it is necessary to remove the core from the bottom of the storage device, put it in a core basket separately attached by a conveyor or the like, and manually transfer the core from the transported core basket to the storage device. there were. There is also a device that places the transported core cage in a fixed position, lifts the core upward by vacuum, and then moves it horizontally to transfer it to the core insertion device. It is shaped and difficult to suck with vacuum. Moreover, when the surface of the old core is scratched, the core cannot be reliably sucked and held by the vacuum, and the core may be dropped during transfer. In addition to the above-mentioned method, there is also a device that sandwiches the core with a pair of claws. In that case, there is a disadvantage that the core must be stored by making a space for the claws to enter, and the amount of storage is reduced. It was.

It is said that. As shown in FIG. 4, the main body beam 41 of the traversing slide device 4 is attached to the slide bearing 55.
[0014]
Further, as shown in FIG. 9, in the traveling slide device 6, a slide bearing 62 is slidably attached to a base 61 positioned horizontally, and a motor 64 and a pinion 65 directly connected to the motor 64 are mounted on the slide bearing 62. The slide bearing 62 can be moved forward and backward along the base 61 via the guide rail 63 by forward or reverse rotation of the motor 64. Further, the lower end of the main column 51 of the elevating slide device 5 is mounted on the slide bearing 62, and the chucking device 3, the transverse slide device 4, and the elevating slide device 5 are accompanied by the traveling of the traveling slide device 6 as shown in FIG. It is possible to move.
[0015]
As shown in FIG. 1, the base 61 of the traveling slide device 6 is arranged orthogonal to the transfer device 7 that supplies the core to the winder W, and has a plurality of core baskets 3 with the front face positioned toward the base 61. The positioning device 2 is installed in parallel. In FIG. 1, reference numeral 71 denotes a tray attached to the transfer device 7. The operations of the chucking device 3, the transverse slide device 4, the lifting slide device 5 and the traveling slide device 6 are not shown, but the core can be held, traversed, moved up and down, and moved by computer control. it can.
[0016]
In the core supply device having the above-described configuration, the motors 57 and 64 of the elevating slide device 5 and the traveling slide device 6 are driven, and the chucking device 3 is designated on the uppermost front surface of the core cage 1 specified from a reference position described later. Move it in front of the core axis. Next, the motor 47 of the traverse slide device 4 is driven to advance the chucking device 3 so that the pipe 32 is inserted into the hollow portion of the core and the air cylinder 33 is operated to hold the core. The motor 57 of the lifting / lowering slide device 5 is driven to move to the upper part of the core basket 2.
[0017]
Next, the motor 64 of the traveling slide device 6 is driven to move the slide bearing 62 along the base 61 to move the core held by the chucking device 3 onto the tray 71 head of the transfer device 7, and further to the traveling slide. The motor 57 of the device 5 is driven to lower the chucking device 3, and immediately before the held core is landed on the tray 71, the air cylinder 33 of the chucking device 3 is operated to release the holding of the core, The motor 47 of the traverse slide device 4 is driven to retract the chucking device 3 and the pipe 33 is pulled out of the hollow portion of the core. At the same time, the lowering of the chucking device 3 is stopped, and the pipe 32 is completely pulled out of the core. The transfer of the book core is completed.
[0018]
Using the retracted position of the chucking device 3 as a reference position, the motors 57 and 64 of the elevating slide device 5 and the transverse slide device 6 are driven again to raise the chucking device 3 in the order of ascending, running and descending. Move the chucking device 3 to the front of the axis of the designated single core for the next removal, and then repeat the same procedure as above to sequentially take out the cores one by one and transfer them. It is supplied to the tray 71 of the apparatus 7.
[0019]
There are various lengths of cores, such as 3/4, 2/3, 1/2, etc., where the longest length is 1, but each core has a different length. If necessary, a core having a desired length can be selected and taken out as required. Further, when the cores having different lengths are loaded on the core car 1, the core holding by the chucking device 3 is easy if the core front end position is always the same. However, as an exception, in the case of a ½ length core, the two on the front side and the back side are loaded as a series. Therefore, when the core on the back side is taken out, the pipe 32 of the chucking device 3 moves forward and backward. It is necessary to extend the working distance in order to pull out the moving distance and the held core to the position of the front end of the front core.
[0020]
Further, the operations of the chucking device 3, the traverse slide device 4, the lifting slide device 5 and the traveling slide device 6 are not shown, but are driven by the air cylinder 33, motors 47, 57, 64, etc. by a computer control system. By the cooperative operation, the core can be automatically moved from the core basket 1 to the tray 71 of the transfer device 7 and finally the target core can be supplied to the winder W.
[0021]
【The invention's effect】
As described above, in the present invention, when supplying a winding core to be used in a winder to the winder, the core is previously loaded on the core basket, and the cores are taken out one by one by the chucking device as they are, and then the traverse slide device. Since the elevating slide device and the traveling slide device are assembled and the cores can be automatically supplied to the winder by the cooperative operation of these devices, there is no need to manually transfer to the storage device, and the efficiency of core supply work is increased. The width can be improved.
