Description

[Detailed description of the invention] The present invention relates to a device for winding and transferring between an upper floor and a lower floor, and in particular combines a hook that moves up and down or swings, a traverser having a drive mechanism, and a lifting mechanism. The present invention relates to a device that can be used to transport the winding very efficiently without damaging the outer surface of the winding.

Conventionally, in paper factories, textile factories, etc., in order to transfer the rolled up spool between the upper and lower floors, the spool of the spool is lifted up by a lifting device such as a crane, There are several methods for transporting the material, such as passing it through a loading port, rolling it by hand, or using a floor conveyor or kick device to transport it to a lift device such as an elevator or bucket conveyor, and then transporting it by the lift device. It has been adopted. However, when using a lifting machine, a large number of workers are required, which places a heavy burden on the workers. Also, when using lift equipment or floor conveyors,
Although the number and burden of workers are reduced, the outer surface of the winding is easily damaged, causing a decrease in yield. especially,
When the roll to be transported is pressure-sensitive recording paper, a new problem arises: the occurrence of scratches and stains.

In view of the current situation, the inventors of the present invention have conducted extensive research to develop a transfer device that can solve the above-mentioned problems, and as a result, they have found a transfer device that does not damage the outer surface of the winding material and places only a small burden on the operator. We have developed a device that is capable of extremely efficient winding and transfer. That is, the present invention provides a traverser that moves on a rail that can be connected to an elevator in a device for vertically transferring winding.
Both ends of the vertical lever are equipped with a vertical cylinder device and a swing cylinder device, and the tip of the rod of the vertical cylinder device and the upper end of the hook rotate around the axis of the block fixed to the frame of the traverser. The hook is moved up and down by sliding the rod, and the tip of the rod of the swinging cylinder device and the center of the hook form a swinging lever with the axis of the block as the center of rotation. It is connected via a link plate, and by sliding the rod, the hook swings to lift, hold, and release the winding, and the drive mechanism moves back and forth to a desired position. A device for vertically transporting a winding material, characterized in that the traverser is configured to be vertically movable between an upper floor and a lower floor by means of an elevator.

The apparatus of the present invention will be explained in more detail based on the drawings. FIG. 1 is a schematic diagram showing an embodiment of a traverser 1 that forms the main part of the present invention. In FIG. 1, only one hook 2 is shown, but there is another hook on the opposite side of the hook, and the hook 2 is composed of a pair. The spacing between the hooks is adjusted to be suitable for lifting the take-up spool. The hook 2 is operated by a hydraulic signal issued from the hydraulic unit 4 based on a signal from the control section 3.
By sliding the rod 6 of the vertical hydraulic cylinder 5, the tip of the rod 6 and the upper end of the hook 2 rotate vertically around the shaft 8 of the plummer block fixed to the frame 7 of the traverser 1. Since it is connected to both ends of the lever 9 for
moved up and down. In addition, the hook 2 is configured by swinging the rod 11 of the swinging hydraulic cylinder 10 so that the tip of the rod 11 and the center of the hook 2 are rotated about the axis 8 of the plummer block. Since it is connected via the swinging lever 12 and the link plate 13, it can swing left and right in the figure.

The traverser 1 has wheels 15 and drive wheels 16 on the bottom, and is driven back and forth on the rail 14 by the operation of a wheel drive motor 17 that is driven based on a signal from the control section 3. Also, hook 2
The movement of the traverser 1 is detected by a sensor such as a phototube or a limit switch, and is based on a program input in advance to the control unit 3 by inputting a signal to the control unit 3.
Automatic control is also possible.

As shown in FIG. 1, by providing at least a pair of appropriately shaped recesses 18 in the upper part of the traverser 1, an empty spool can be placed on the recesses 18 when the traverser 1 is transported.

FIG. 2 is a schematic diagram showing a case in which the winding 19 that has descended to the reel part of the paper machine is unloaded from the second floor to the first floor by the device of the present invention. Lifting mechanism 20 on the second floor
is in a standby state with traverser 1 on board. When the reel 19 is placed on the reel table 21 by a reel crane or the like, the control unit 3 issues a "reel hoist" signal based on a program input in advance. The traverser 1 advances to the winding delivery position, lifts the winding 19 from the winding table 21 by operating the hook 2, and
The lifting mechanism 20 returns to the standby position again.

To explain this lifting operation in detail, first, the swinging hydraulic cylinder 10, which is a swinging cylinder device, is operated to swing the hook 2 to the left in the figure in preparation for the transfer of the winding, and then the traverser 1 is Hook 2 in a swinging state after advancing to the delivery/delivery position
By returning the hook 2 to its original position, it can be brought securely to the bottom of the winding shaft.Next, the vertical hydraulic cylinder 5, which is a vertical cylinder device, is activated to lift the hook 2 upward in the figure and wind it. can be kept in a non-contact state.

Subsequently, the lifting mechanism 20 descends to the first floor in response to the "lifting mechanism lowering" signal from the control unit 3, and the traverser 1 lowers the loading and unloading of the chain conveyor 2 in response to the "winding loading/unloading" signal. Move forward to position and hook 2
The winding 19 is lowered onto the chain conveyor 22 by the operation.

To explain this lifting and lowering operation in detail, first, the vertical hydraulic cylinder 5, which is a vertical cylinder device, is activated to lower the hook 2 to lower the winding to the winding and delivery position, and then the swinging cylinder device is activated. When the swinging hydraulic cylinder 10 is operated to swing the hook 2 to the left in the figure, the hook 2 can be reliably removed from the winding shaft.

Thereafter, in response to a "traverser standby" command from the control section 3, the traverser 1 returns to the standby position within the lifting mechanism 20 and becomes standby for the next winding.

According to the winding vertical transfer device of the present invention, as described above, the vertical movement of the hook 2 during the lifting and unloading operations of the winding is combined with the left and right swinging movement, so that high quality printing paper can be obtained. It is possible to transfer the winding very efficiently without damaging the outer surface of the winding, which is extremely susceptible to scratches, and the number of workers and the burden on the workers can be greatly reduced. In particular, the effect can be further enhanced by automating the process.
