2. Description of the Related Art As one of bookbinding products, there is a booklet in which a central portion of a booklet is bound with a wire, and the bound portion is folded in two. In the case of creating such a book, for example, a paper stacking machine that aligns and stacks one sheet of paper printed on each page (hereinafter, referred to as a sheet including this sheet), and a sheet bundle that is stacked for one book. A paper binding machine that binds with wire, a paper folding machine that bends a bundle of bound paper, a cutting machine that trims the edges (edges and tops) of the folded bundle, and a booklet receiver that receives and stores the cut bundle of paper The book is prepared and sequentially passed through each of these machines for bookbinding.

In this case, these machines are arranged and arranged in a row in close proximity to the discharge port of the printing press, and the discharged paper of the printing press is sequentially passed through each machine for bookbinding.
It is convenient to transport paper and booklets, but a large space is required to arrange each machine in a line, and if the space is narrow, each machine must be placed separately, and the paper and booklet between There is a problem that the transfer is troublesome and troublesome.

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 with a reduced useless space. FIG.
FIG. 1 shows a schematic configuration of a bookbinding apparatus (not known) developed in this manner. In FIG.
Is a bookbinding device. In the bookbinding apparatus 2, a paper binding mechanism 3 is arranged at the uppermost position, and in the lower part of the bookbinding apparatus, two-stage paper feed mechanisms 4 and 5 for supplying a cover and an insertion sheet are arranged. A cutting mechanism 8 and a booklet receiving mechanism 6 for receiving and storing the cut sheet bundle are arranged below the lower sheet feeding mechanism 5, and a sheet folding mechanism 7 extending in the vertical direction is arranged at an end. Further, a paper feed mechanism 11 for supplying auxiliary paper or the like to the paper carry-in position is arranged.

The paper binding mechanism 3 includes a stitcher 3a for binding the paper with a binding staple and a stopper 3b for stopping and positioning the incoming paper. The stitcher 3a binds flat (to bind one edge of the paper) and a corner. In accordance with the binding (binding at one corner of the sheet) and the saddle stitching (binding at the center of the sheet), the position can be changed (the figure shows a case where the sheet is at the saddle stitching position).
b is configured to be movable back and forth in the paper transport direction according to the size of the paper to be bound, and to be able to retreat from the transport path when unloading the bound paper bundle.

That is, when performing sheet binding, the stopper 3b is projected onto the conveyance path at a position corresponding to the size of the sheet, the stitcher 3a is set at the binding position, and is sent from the printing machine 1 to the stopper 3b and is carried in. Roller 10a

The saddle-stitched booklet has a bulge on the back surface and has elasticity even when pressed down, so that it is difficult to vertically align the booklet. For this purpose, a method of discharging a saddle-stitched booklet exclusively in a pinch-like manner (semi-overlapping state) on a transport belt or, in a simpler case, discharging the booklet on a bucket is adopted. However, when all the machines required for binding and folding are stored in one box as in the above-described bookbinding apparatus, the space for storing the booklets is narrow, and a large number of booklets are discharged in the form of being stacked on a mounting table (see FIG. 4). There is a problem that it cannot be stored. Further, if the booklets are arranged vertically and aligned, a larger number of booklets can be stored, but there is a problem that work for the booklet is required and it takes time and effort.

SUMMARY OF THE INVENTION The present invention has been made in view of such a problem, and enables a booklet folded in a saddle-stitched state to be arranged vertically without any trouble. It is an object of the present invention to provide a booklet vertical alignment device capable of storing a booklet.

According to a second aspect of the present invention, in the first aspect, the guide plate is capable of holding one end of the booklet carried on the mounting table, and releases the holding when the pusher plate is pushed out of the booklet. It is characterized by the following.

In the present invention, when a booklet conveyed horizontally is loaded and aligned vertically on the mounting table, the backup plate is positioned at a position separated from the pusher plate by the pushing movement distance of the pusher plate. The plate is moved downward to change the horizontal direction of the booklet to the vertical direction, and the booklet is loaded between the pusher plate and the backup plate. After being carried in, the pusher plate pushes out the booklet and presses the booklet against the backup plate, and the pusher plate together with the backup plate returns to the original position after reaching the maximum moving distance position.

The backup plate retreats from the position of the maximum movement distance of the pusher plate by the thickness of the booklet and stops, and holds one side of the booklet at that position. When the pusher plate returns to the original position, the holding plate (projecting and retracting at the position where the pusher plate is pushed to the maximum movement distance) protrudes and holds the other side of the booklet. This operation is repeated each time the booklet is carried in, whereby the booklet can be vertically arranged and aligned.
Further, at the time of loading, if one end of the booklet is held by the guide plate, it is possible to prevent the booklet from being opened at the time of loading.

Further, according to the present invention, a booklet conveyed in a horizontal direction can be carried in and stacked on the mounting table as it is. In this case, the guide plate is moved upward and placed, the holding plate is kept in the retracted state, the movement of the pusher plate is stopped and fixed, and the backup plate is moved backward to move between the backup plate and the pusher plate. And throw out the booklet that is transported sideways.
