BACKGROUND OF THE INVENTION
The present invention relates to a paper piece peeling device, and more particularly, to a paper piece peeling device that favorably peels and collects a paper piece such as a slip attached to a cargo such as a large capacity product.
[0002]
[Prior art]
Paste slips, instructions, and other paper pieces on the cargo or other cargo that is being transported or stored in such a way that it can be peeled off at a part of the center, etc., and peels it off and collects and discards it when receiving and collecting cargo. This is a common practice.
However, the separation and collection of these sticky paper pieces must also be complicated when a large number of objects are processed continuously. Smooth processing is required for collection and delivery.
[0003]
For example, when canned beverages are shipped, a predetermined number of beverage cans are shrunk in parallel, stacked in multiple layers and fastened with a tightening band such as polypropylene, and a slip is attached to the surface of the tightening band. Yes.
In consideration of the convenience of separation and collection at the time of receipt of these slips, only the substantially central part is stuck with hot melt so that the separation is possible. However, it is not always easy to orderly separate, collect, and discard slips while securing a quick and smooth work process in handling a large amount of continuously collected products.
[0004]
[Problems to be solved by the invention]
When looking at this type of work in the past, slips that were peeled off from the tightening band and slip pieces that had failed to peel off dissipated, creating a great burden of collection and disposal, and they were further left behind in the resin tightening band. Separation and disposal of slip pieces and tightening bands is practically impossible, leading to undesirable results in terms of environmental conservation.
[0005]
In this respect, the efficiency of the peeling work itself has been considered conventionally, and the adhesive surface of the gum tape, which is superior to hot melt in terms of adhesive strength, is pressed against the slip surface attached to the tightening band and peeled off. There is also a method of winding and collecting.
However, in this method, the gummed tape that has been peeled off and collected is inevitably large, and the workability is poor and the subsequent processing load is increased. In addition, a method of cutting the tightening band with the slips attached is proposed, but this method only has the meaning of skipping the slip peeling during the receiving operation and postponing the subsequent work. In addition, it is extremely difficult to separate and collect the slips from the tightening band pieces that are left in large quantities in a mixed state, compared to the slip peeling at the time of receiving work placed in a peelable state, I have to say that it is virtually impossible.
[0006]
SUMMARY OF THE INVENTION The present invention has been made in view of such a problem, and the object of the present invention is to remove a piece of paper that regularly removes and collects a piece of paper such as a slip attached to a large capacity product or cargo so as to be peeled off. The device is on offer.
