Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention has a function of storing copies and printed matter of the same original or the same plate in the same bin in a copying machine or printing machine, and a function of storing the copies and printed matter from each bin. The present invention relates to a sheet sorting and collating device that has a function of taking out printed matter one by one and sequentially creating a group of sheets.

[Prior art]

Recently, especially in the field of office copying and printing,
In addition to improving the processing capacity of the copying machine or printing machine itself, it also saves labor and speeds up the creation of manuscripts or printing plates, and when viewed comprehensively, it improves copying,
A major factor is improving the efficiency of sorting and collating work as post-processing of the printing process.

Conventionally, for example, in the case of a copying machine, in order to sort sheets copied from the same original to create a group of multiple copies, it is necessary to (1) store copies from the same type of original in the same bin; Alternatively, the sheets are sorted using a zigzag collator, and when all the originals have been copied, the same copies are manually stored in each bin of the sorter, and then the sorter is driven to arrange the sheets in page order. (2) Means for forming a group of sheets arranged in page order by sequentially sorting and storing copies from the same original into each bin of a sorter one by one.

However, with the method (1) above, it is necessary to combine a sorter in addition to a collator for sorting, which not only requires a large installation space and work space for the device, but also requires a separate sheet for each bin. This method requires a lot of work time because it is necessary to move the group manually, and has the disadvantage that workability is extremely poor. In addition, method (2) requires more bins than the required number of copies.
The disadvantage is that the device itself becomes extremely large, requires a large installation space, and is expensive. on the other hand,
Commonly supplied sorters are typically 20 bins (20
As a result, there are problems such as making it unsuitable for creating a large number of documents.

〔the purpose〕
