CONSTITUTION:A carrier vehicle 5 is moved to the position of a roll paper wind-up core 1a on service which will be soon emptied, by rotating a handle 14, and hooks 9 are moved by rotating a handle 12 to stand by at positions direct below both ends of the roll paper wind-up core 1a which will be soon emptied. When the roll paper is completely paid out from the wind-up core 1a, the handle 12 is at once rotated to take up the emptied wind-up core 1a by means of the hooks 9 from a bearing section of a carrier bed. Then, the handle 14 is rotated to move the carrier vehicle 5, and then a handle 13 is rotated to lower a full wind-up core 1b which has been held on hooks 9' to set the same onto the bearing section of the carrier bed, thereby the replacement between the emptied wind-up core 1a and the full wind-up core 1b is completed.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is directed to a roll paper winding shaft on which wrapping paper is wound into a roll, and a roll paper winding shaft in which wrapping paper is wound into a roll so that wrapping paper can be continuously supplied when automatically wrapping coils. This is a device that allows you to quickly replace a worn-out winding shaft.

[Prior art] Since the length and width of coil wrapping paper vary depending on the coil diameter and the size of the coil, a roll paper winding shaft with various types of wrapping paper wound into rolls is mounted on a support shaft on a stand, and the coil A roll paper having a width corresponding to the width of the roll paper is pulled out and fed to the coil wrapping position. However, when replacing the empty winding shaft after pulling out the roll paper with the actual winding shaft wrapped with roll paper, ,
First, the empty winding shaft is removed from the mount using a crane and transported to the stockyard, and then the actual winding shaft is brought in from the stockyard using a crane and mounted on the mount. It takes a long time, about 15 minutes, for multiple workers to mount the actual winding shaft suspended by a crane in a predetermined position on the stand because the suspended winding shaft swings in the air. Was.

Therefore, there is no paper roll on the take-up shaft.

Problems to be Solved by the Invention As mentioned above, when all the roll paper on the winding shaft is pulled out, the packaging operation has to be interrupted for about 15 minutes until a new roll paper winding shaft is placed on the supply shaft. Therefore, the efficiency of the packaging operation (it was difficult to do it quickly).

Furthermore, when attempting to quickly mount the actual winding shaft in a suspended state on a support shaft, not only a large number of workers are required, but also the danger of the shaft mounting operation increases.

Means for Solving the Problems The present invention provides a roll paper winding shaft exchange cart that runs in a direction perpendicular to the winding shafts on a pedestal on which a large number of roll paper winding shafts are supported in parallel. A hook that pulls out the roll paper and removes the empty take-up shaft from the stand, and a hook that pulls down the new take-up spindle with rolled paper onto the stand and hangs it on the stand, are each attached so that they can be raised and lowered. This is a take-up shaft exchange device.

Operation: A rotating crane installed on the side of a pedestal on which many take-up shafts wrapped with roll paper are arranged side by side and supported by the support shafts is installed. A new roll paper winding shaft is supported on one hook of the winding shaft exchange cart based on prior consideration for replenishing the paper roll.

When a specific roll paper in a drawer, which is mounted on a support shaft on a stand, becomes empty, the hook that receives the empty winding shaft of the exchange trolley that moves to that position and waits pulls up the empty winding shaft, The exchange cart is moved so that the hook supporting the empty winding shaft is directly above the bearing on which the empty winding shaft is mounted, and the hook is immediately lowered to remove the empty winding that has already been pulled up. By supporting the take-up shaft on the support shaft mounting device, the empty and real take-up shafts can be quickly exchanged and supported.

Embodiment A swing crane 3 is attached to a support installed on the side of a pedestal 2 of an automatic wrapping paper feeder in which a large number of roll paper winding shafts 1 are supported in parallel. A hoist 4 for lifting and transporting is provided.

The frame 2 is provided with a pair of rails 6.6 for guiding a roll paper take-up shaft exchange cart (hereinafter simply referred to as a cart) 5 to run above the take-up shaft 1 in a direction perpendicular to the take-up shaft 1. A plurality of wheels 7 are mounted which run on rails 6.6.

The roll paper P wound around the take-up shaft 1 has a large weight of about 200 kg, and a pair of pinch rollers R provided below the take-up shaft 1
, R' and pulled out from the winding shaft l, and conveyed to the coil packaging position by the clamping conveyor belt devices c and c', but this is not the gist of the present invention, so a description thereof will be omitted. (
(See Figures 1 and 2) Reference numerals 5a and 5b are handrails erected on both sides of the truck 5, and 5C is a ladder for workers to get on and off the truck.

As shown in FIG. 3, the bogie 5 has a pair of sprockets 8a, 8b and 13 spaced up and down, respectively, in the front and back of the bogie running direction.
chains c and 3d are disposed, and chains c and c' are vertically suspended from each pair of sprockets;
A hook rod 10 with hooks 9 and 9' provided on a part of c'.
10' is tied together, and the hook rod 10.10' is raised and lowered by the reciprocating rotation operation of the chain C1C' along the upright guide column 11.11'.

One hook rod 10 drives the sprocket 8a by rotating a handle 12 attached to the trolley 5 to raise and lower the chain C, and the other hook rod 10' drives the sprocket 8C by rotating a handle 13 attached to the trolley. By driving the chain C' and raising and lowering the chain C', each chain C' can be raised and lowered independently.

A handle 14 attached to the truck 5 drives the wheels 7.7 of the truck by a chain transmission to move the truck forward and backward.

In FIG. 3, an empty winding shaft la is supported on a hook 9, and a real winding shaft 1b is supported on a hook 9'.

Therefore, the handle 14 is manually rotated to move the cart to the position of the take-up shaft in use where the roll paper on the take-up shaft is likely to be empty, and the handle 12 is rotated to move the hook 9. The winding shaft is placed on standby immediately below both ends of the winding shaft.

When the roll paper on the winding shaft runs out, that is, the winding shaft becomes empty, the handle 12 is immediately rotated to pull up the empty winding shaft from the stand bearing, and then the handle 14 is pulled up.
The hook 9', which previously supports a new take-up shaft (actual take-up shaft) on which the roll paper is wound, is positioned directly above the pedestal bearing part from which the empty take-up shaft was lifted. like 1
Move the trolley, then rotate the handle 13 to lower the hook 9', support the actual winding shaft on the frame bearing from which the empty winding shaft has been pulled up, and connect the empty winding shaft with the actual winding shaft. Finish replacing the actual winding shaft.

Then, the empty winding shaft supported by the hook 9 is suspended by a hoist of a rotating crane and transported to the empty winding shaft stockyard, and then the next full winding shaft is hung by the hoist. The work is completed by supporting it on the foot 7' of the truck and leaving the truck on standby.

Effects of the Invention The present invention comprises a traveling carriage placed on a frame on which a large number of roll paper winding shafts are mounted, and an empty winding shaft supporting hook and a real winding shaft supporting hook that are independently raised and lowered on the trolley. The actual take-up shaft, which is to be replaced with the empty take-up shaft, is carried in and supported by the actual take-up shaft support hook in advance by a rotating crane, so that all the roll paper is pulled out and the empty take-up shaft is supported. When it comes to the shaft, the actual winding shaft supported on the trolley can be immediately replaced with the empty winding shaft, and the rotating crane allows
It took several workers approximately 15 minutes to directly replace the empty winding shaft on the stand with a real winding shaft, but in the present invention, the empty winding shaft and the real winding shaft can be replaced by a trolley. The replacement work could be completed in about 2 minutes by one worker.

Therefore, when the roll paper is continuously fed to the packaging work position, the winding shaft can be replaced in a short time, so the packaging work can be performed continuously with almost no interruptions. Moreover, since the danger of replacing the winding shaft is eliminated, the packaging work can be carried out smoothly and efficiently, and the effect is significant.
