Description

Detailed Description of the Invention This invention supplies base paper from a base paper stocker to a mill roll stand (base paper hanger) of a corrugator, and supplies used residual base paper (hereinafter referred to as residual base paper) removed from the mill roll stand. ).

The current supply and conveyance of new base paper from the base paper warehouse or base paper stocker to the mill roll stand of the corrugator and the removal of remaining base paper from the stand move forward and backward on the guide rails laid down to the mill roll stand. It is carried out using a single trolley that can be mounted freely.

In other words, when the base paper that was hung on the mill roll stand is used up and you want to replace it with new base paper, first move the trolley empty to the center line of the mill roll stand, and remove the remaining base paper from the mill roll stand. Place it on the trolley, then move the trolley backwards and unload the remaining paper at the remaining paper outlet.
The empty trolley is moved to the base paper warehouse or base paper stocker, loaded with new base paper, and moved forward again to the mill roll stand, where the new base paper is hung on the base paper rack from which the remaining base paper has been removed. After that, the truck was moved backwards.

Therefore, the entire process from discharging the remaining base paper to supplying and transporting new base paper requires one cart to be moved back and forth to the mill roll stand twice, which takes a considerable amount of time and reduces the work load. There are problems in improving performance and productivity.

Also, load new base paper onto one trolley and move it forward to the mill roll stand, unload the new base paper from the trolley and place it near the mill roll stand, remove the remaining base paper from the mill roll stand, and place it on the empty trolley. and then onto the empty mill roll stand.
It is also conceivable that the new paper that has been unloaded first is carried and hung, and then the trolley carrying the remaining paper is moved backwards, but in this case, it would be very labor-intensive to replace the new paper, and it would be difficult to remove the new paper. A place is also required to temporarily store the material after it is unloaded from the cart, and as a result, the current situation is that one cart is used to supply and transport the material twice.

Therefore, the present invention solves the above-mentioned conventional problems and can significantly shorten the supply and transportation time of base paper.
This paper is designed to improve workability and productivity, and its base paper supply and transportation method connects two carts for transporting new base paper and used leftover base paper.
When the carts move forward, one cart is loaded with new base paper for supply and moved forward, and the other empty cart is stopped on the line of the mill roll stand holding the remaining base paper,
Remove the remaining base paper from this stand and place it on an empty trolley, then move those trolleys, stop the new base paper loading trolley on the center line of the empty mill roll stand from which the remaining base paper was removed, and then remove the new base paper from that trolley. After unloading the paper and hanging it on the empty mill roll stand, both carts are moved backwards, and the remaining paper loading cart is placed at the remaining paper discharge device, and the empty cart after unloading the new paper is placed at the paper stocker. stop each,
The purpose is to unload remaining paper and load new paper.

Hereinafter, one embodiment of the present invention will be explained based on the drawings in order from the supply conveyance device used to carry out the present method. In the first and seventh figures, 1 is a mill roll stand of a corrugator, 2 is a base paper conveyance path. 3 is a base paper stocker installed near the middle of the guide rail 2; 4 is a remaining base paper discharge device installed near the middle of the guide rail 2; It is installed at an appropriate distance from the stock stocker 3, and its installation position may be on the opposite side of the guide rail 2 as the paper stocker 3, or on the same side as the paper stocker 3. The position may be either on the side closer to the mill roll stand 1 or on the opposite side.

On the above-mentioned guide rail 2, connected carts 5 and 6 are attached so as to be able to move forward and backward.

The connection interval between the carts 5 and 6 is equal to the mounting interval between the paper stocker 3 and the remaining paper discharge device 4, and the center position of one of the carts 5 is placed on the center line of the paper stocker 3. When combined,
The center position of the other cart 6 is the remaining paper discharge device 4
so that the matching position is on the center line of

Further, for the forward and backward movement of the carts 5 and 6, it is conceivable to connect them to a driving chain, or to make them self-propelled by integrally attaching a driving source to the carts themselves.

Next, to explain this method using the above-mentioned device, first, the trolley 5 is moved to the base paper stocker 3.
new base paper 7 on the trolley.
(Fig. 3), and then the carts 5 and 6 are moved forward and stopped when the cart 6 is located on the center line of the mill roll stand 1 (Fig. 4).

In this state, remove the remaining base paper 8 from the mill roll stand 1 and place it on the trolley 6 (Fig. 5), and after completion,
The carts 5 and 6 are moved forward, the rear cart 5 on which the new paper paper 7 is placed is stopped on the center line of the empty mill roll stand 1 (Fig. 6), and the new paper paper 7 on the cart 5 is lowered. and hang it on the mill roll stand 1 (Figure 7).

After completing the work of hanging new paper 7, carts 5 and 6
is moved backward, and the cart 6 carrying the remaining paper 8 is stopped on the center line of the remaining paper discharge device 4, and the cart 5 is stopped on the center line of the paper stocker 3 (FIG. 8). The remaining base paper 8 on top is unloaded onto the remaining base paper discharge device 4, and new base paper 7 necessary for the next base paper exchange is loaded onto the cart 5 and waited until the next time for base paper exchange.

Therefore, supplying and transporting new base paper and discharging remaining base paper can be completed in one round trip of two connected carts, and the transport time is half that of the conventional system, improving workability and productivity. It is.

Furthermore, on the left and right sides of the guide rail 2 on the center line of the mill roll stand 1, and on the sides of the guide rail 2 on the center line of the remaining paper discharge device 4, there are paper sheets loaded on carts 5 and 6, respectively. By installing an automatic sorting device (not shown) that distributes and unloads the materials to the left and right sides of the guide rail 2, work efficiency can be further improved.

Furthermore, by attaching a stopper 9 to the guide rail 2 in order to restrict the movement range of the carts 5 and 6,
The carts 5 and 6 can always be stopped at a fixed position.

The present invention uses the conveying method as described in detail above, so that the feeding and conveying of new base paper and the carrying out of remaining base paper can be carried out.
This can be completed in one round trip of two connected trolleys, reducing the transport time to half compared to the conventional two round trips, and improving workability and productivity. .
