[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a sheet cutting mechanism.
[0002]
[Prior art]
As one of the bookbinding products, there is one in which the central portion of the booklet is bound with a wire and the bound portion is folded in two. When creating such a bookbinding product, for example, a paper stacking machine that stacks and stacks one sheet of paper printed on each page (hereinafter referred to as paper including this paper), and a bundle of sheets stacked for one book. Paper binding machine that binds paper with a wire, paper folding machine that folds a bundle of paper after binding, a cutting machine that trims the edges (small edges and top and bottom) of the folded paper bundle, and a booklet receiver that receives and stores the cut paper bundle Are prepared and passed through each of these machines in sequence.
[0003]
In this case, if these machines are arranged in a row in close proximity to the discharge port of the printing press, and the paper discharged from the printing press is sequentially passed through each machine, the paper and booklet can be transported. It is convenient, but it takes a lot of space to arrange each machine in a row, and if the space is small, each machine must be placed separately, and it takes time and trouble to transport paper and booklets between them. There is a problem that.
[0004]
In order to solve this problem, a bookbinding apparatus has been developed in which each machine is miniaturized as much as possible, and each machine is installed in one box while reducing useless space. FIG. 5 shows a schematic configuration of a bookbinding apparatus (not known) developed in this manner. In this figure, 1 is a printing machine and 2 is a bookbinding apparatus. In the bookbinding apparatus 2, the sheet binding mechanism 3 is arranged at the uppermost position, and in the lower stage, in this bookbinding apparatus, two-stage sheet feeding mechanisms 4 and 5 for supplying cover sheets and insertion sheets are arranged. A cutting mechanism 8 and a booklet receiving mechanism 6 for receiving and storing the cut sheet bundle are disposed below the lower sheet feeding mechanism 5, and a sheet folding mechanism 7 extending in the vertical direction is disposed at the end. A paper feed mechanism 11 for supplying auxiliary paper and the like is disposed at the paper carry-in position.
[0005]
The paper binding mechanism 3 includes a stitcher 3a that binds paper with a binding needle and a stopper 3b that stops and positions the incoming paper. The stitcher 3a binds flatly (binding one edge of the paper) and corner binding (paper). The position of the sheet is movable (the figure shows the case where the sheet is in the saddle stitching position), and the stopper 3b is bound to the sheet to be bound. Depending on the size of the paper, it can be moved forward and backward in the paper conveyance direction, and can be retracted from the conveyance path when carrying out the bound paper bundle.
[0006]
That is, when sheet binding is performed, the stopper 3b is projected on the conveyance path at a position corresponding to the sheet size, the stitcher 3a is set at the binding position, and is sent from the printing machine 1 to the stopper 3b. When the paper 9 conveyed via the feed roller 10b and the paper conveyed via the feed roller 10b from the paper feeding mechanisms 4, 5, and 11 are contacted and positioned appropriately, and one sheet of paper is accumulated, the stitcher 3a is driven to bind a bundle of sheets for one book.
[0007]
After binding, the stopper 3b is retracted from the conveyance path, and the bound sheet bundle, that is, the booklet 9a, is carried out to the sheet folding mechanism 7 while changing the conveyance direction to the vertical direction. When the folding process is not performed, for example, when the binding process is not performed, or when the flat binding and the corner binding are performed at different locations, the direction is not changed, and the sheet is directly carried out to the next process.
[0008]
The sheet folding mechanism 7 is arranged in a vertical direction for guiding and holding a folding blade 7a movable to the left and right, a pair of pressure conveying rollers 7b, a movable stopper 7c that moves up and down according to the folding position, and a booklet 9a. A pair of guide plates 7d is provided, guided between the pair of guide plates, carried in, and placed between the pair of pressure-conveying rollers 7b by applying the folding blade 7a to the folding position of the booklet 9a positioned in contact with the stopper 7c. The booklet 9a is bent by press-fitting into the sheet. The folded booklet 9 a is carried out to the cutting mechanism 8.
[0009]
The cutting mechanism 8 extends along a conveyance path along which the folded booklet 9a is conveyed, a cutting table 8b that straddles the conveyance path and touches the lower surface of the booklet 9a, and an edge corner of the cutting table 8b. The booklet 9a is arranged on the upper surface of the booklet 9a, and includes a movable cutting blade 8a that moves up and down, and a drive mechanism that drives the cutting blade 8a (not shown). Then, the cutting blade 8a is driven downward, and the booklet 9 cuts out the edge of the booklet 9a. The cut booklet 9 a is carried out to the booklet receiving mechanism 6. The booklet receiving mechanism 6 includes a loading table 6b on which the carry-in roller 6a and the booklet 9a are placed, and stores the booklet 9a that has been loaded vertically or horizontally on the placement table 6b. In addition, the figure has shown the case where it puts vertically.
[0010]
In the bookbinding apparatus configured as described above, one sheet of paper loaded from a printing machine or the like is collected at the binding position, so that a separate paper stacking machine for that purpose can be omitted. In addition, since the booklet transport direction after binding is reversed to the paper carry-in direction by using a folding function at the paper folding position, cutting and storing are performed, so that space can be used efficiently and the machine required for bookbinding (binding folding) Installation space can be greatly reduced.
[0011]
