2. Description of the Related Art Conventionally, as shown in FIG. 6, a required number of printing sheets 31 conveyed by a conveyor 30 from a printing machine (not shown) are divided into small bundles for a predetermined number of sheets, and then a belt. The sheets are temporarily received in a stacked state on the temporary receiver 33 via the conveyor 32. Then, the small bundled printing book 31 stacked on the temporary receiver 33 is
After being handed over the small bundle-shaped stack of books stacked on the pedestal 34,
It descends again and is transferred by the pusher 35 onto the lifting table 37 directly below the large bundle-shaped stacking section 36.
The small bundle-shaped printing book 31 that is raised by 37 is stacked thereon is held in a stack by the holder 38 of the large-bundle stacking portion 36 and stacked in a large bundle.

[0003]

By the way, in the above-mentioned conventional apparatus, when the small bundle-shaped printing book 31 on the elevating table 37 is lifted up to the large bundle-shaped laminating portion 36 at the upper position and stacked, it is formed into a small bundle. Since the uppermost layer portion of the stacked brushes 31 is in a free state, when it is raised up to that point, when the uppermost layer of the brushes 31 comes into contact with the lower surface of the holder 38 of the large bundle-shaped laminated portion 36, 31
In addition, there is a problem in that the paper misalignment occurs, and especially in the case of a half-folded book, the paper misalignment easily occurs.

In order to prevent misalignment of the printed book and its paper, the timing of opening and closing the holder 38 of the large bundle-shaped stacking portion 36 is set according to the type and stacking height of the printed book stacked in a small bundle. There is a problem that it is necessary to make adjustments each time, and the adjustment work requires a lot of trouble. The present invention has been made in view of the above circumstances, and an object of the present invention is to prevent misalignment of a printing book and its sheets at the time of stacking, and to adjust opening / closing timing of a holder of a large bundled printing book stacking section. An object of the present invention is to provide a collection device of unnecessary printed books.

[0005]

In order to achieve the above object, the present invention takes the following technical means. That is, the present invention includes a laminated base for stacking the small bundles book blocks, a lifting body for supplying to the large bundle book blocks stacked portion is raised the small bundle book blocks on said stacking bases, on the lifting body Installed on the side of the stacking table so that the small bundled book is lifted together with the lifting body while being pressed from above.
It is characterized in that a freely pressing body vignetting opening and closing rotation.

[0006]

According to the present invention, in the small bundled printing book stacked on the stacking table, the uppermost layer portion is pressed by the closing rotation of the pressing body, and the elevating body rises up to the pressed state. The pressing body rises together. At the time when the small bundled book approaches the upper large bundled book on the way up (the upper limit of the pressing body), it temporarily stops, and the pressing body first opens and rotates outward to release the press of the book. Subsequently or at the same time, the holder of the large bundled printed book stacking portion is opened and rotated outward, and when the lifting body is further raised in the holder open state and reaches the upper limit, the holder is closed and rotated inward. The large bundle of books accumulated by the lowering of the elevating body is held by the holder, and the small bundle of books is stacked on the large bundle of book stacks in this manner. Then, the elevating body descends until the upper surface thereof becomes substantially flush with the stacking stand, waits for the next stack of small bundled prints, and when the small bundled prints are stacked again on the stacking stand, The pressing body is closed and rotated to press the small bundled book, and the above-described operations are sequentially performed. Therefore, when the holder is opened and rotated, the small bundled book in the uppermost layer is not scraped by the holder to cause paper misalignment, and the stacking is performed in an orderly manner.
