Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a supply device for supplying a web to a rotary printing press.

2. Description of the Related Art Conventionally, web feed to a rotary printing press has been usually performed manually by hand. That is, a worker rolls and transports a packaged roll of paper from a roll paper warehouse, mounts it on a printing press, unpacks the packing material, and prepares for paper splicing preparation.

In recent years, the transport of webs has been automated by conveyors and the like. In addition, very few newspaper companies have introduced an automatic splicing and tailoring apparatus that automatically performs tailoring in preparation for splicing.

Regarding the removal of the packing material, a device for removing the packing material at the end face portion of the packing material in which the roll paper is packed has been developed by the present applicant, and is proposed in Japanese Patent Application Laid-Open No. 1-1103293.
Regarding the removal of the packing material from the peripheral surface of the web, an automatic device has recently been developed by the present applicant and a patent application has been filed (Japanese Patent Application No. 1-89117).

[Problems to be Solved by the Invention] In the above-mentioned prior art, it is very heavy labor to carry a web of nearly 1 ton in manual labor. Also,
When unpacking the packaging material, cutting only the packaging material with a blade without damaging the contents is a task that requires considerable skill and is nervous. Since the tailoring work is directly related to the success or failure of the splicing, it is a very nervous and time-consuming work. As described above, there are various problems in the method of manually supplying the web.

Also, in the prior art, some processes are automated, such as transporting and tailoring the web, or removing the packing material from the end surface of the web, but in these processes, the other processes must rely on humans. The number of workers cannot be reduced significantly.

[Means for solving the problem]

The present invention is intended to solve such a conventional problem.
A roll paper storage for storing the roll paper with its peripheral surface and the end face packed in a packing material, an end face removing device for removing the packing material on the roll edge from the rolled paper taken out of the roll paper storage, A peripheral surface removing device that removes the packaging material on the peripheral surface from the web after removing the packaging material on the end surface, a tailoring device that performs tailoring in preparation for splicing the web; By arranging the device and the transport device that transports between rotary printing presses,
The gist of the present invention is to completely eliminate the supply of web paper to a printing press.
