Description

  The present invention relates to a method and apparatus for supplying unprinted paper in a single-sided printing machine.

  Conventionally, a printing machine is composed of a double-sided printing machine and a single-sided printing machine. The former is extremely expensive, and the machine body is large, and therefore occupies a large place in the factory. On the other hand, the latter single-sided printing machine is lower in price than the former and occupies a relatively small space.

  However, in order to print both sides of the printing paper using this single-sided printing machine, that is, to perform double-sided printing, first, a large number of sheets on which one side of the paper is printed are waited on the discharge side of the single-sided printing machine. It is necessary to reverse a large number of sheets that have been waiting (up to 8000 to 10,000 sheets), turn the unprinted side up, and move again to the paper feed side of the printing machine to print the remaining unprinted side there were.

  However, there are a large number of sheets to be printed using a printing machine, and an appropriate number of sheets printed on the paper discharge side of this printing machine are bundled, and this paper is moved again to the paper feeding side of the printing machine and stacked. This operation is complicated because manual reloading is the mainstream.

  In particular, the large paper size, such as A version, Chrysanthemum version, 46 version, etc., and the weight increases further depending on the paper quality, and the work of reversing and moving these large paper sizes in large quantities requires physical strength, Even skilled workers were very hard labor.

  On the other hand, a technology of an apparatus for automatically feeding in a printing machine has been disclosed. For example, as in Patent Document 1.

  However, this disclosed Patent Document 1 is not related to a single-sided printing machine and does not feed printing paper.

  In addition, there is a printing press provided with a paper feeding device. For example, as in Patent Document 2.

  However, this disclosed technique is not used for a single-sided printing machine, and printing uses a paper feeding device that supplies a spare ticket for printing a missing number, and rotates. This relates to a table type printing machine, and the printing speed was only extremely slow.
