Description

Description: TECHNICAL FIELD The present invention relates to a method and an apparatus for supplying a printing book coming out of a printing process to a bookbinding process.

[Prior art] Printed materials such as magazines and catalogs are formed by printing a cover, a table of contents, a pictorial image, a body of text, etc. in a printing process, and then transporting these to a bookbinding process, where the saddle stitcher or a wireless stapler is used. It is produced by being bundled as one printed matter by a bookbinding machine such as a machine. Here, the printing book must be transported from the printing process to the bookbinding process.However, conventionally, a predetermined number of printing books are accumulated on a stacker, and a sheet or a plate is applied to both ends, and the periphery thereof is bundled with a band, This was manually stacked on a wooden pallet and transported to a bookbinding machine by a forklift or a self-propelled transporter. And
In the bookbinding process, the bundle was unwound manually and placed on a feeder of a bookbinding machine to be supplied.

[Problems to be Solved by the Invention] However, in such a conventional method, since the transport operation is performed in a state in which the periphery of the bundle of prints is bound by a band, the prints located near both ends of the bundle are handled. Damage or twisting of the bundle can occur. For this reason, when setting the conveyed bundle of printing books in the feeder of the bookbinding machine, there is a problem that it is necessary to remove the damaged printing sheets at both ends and to correct the twist. Further, in the case where the backing plate was applied to both ends and tied with a band, there was no damage at both ends, but twisting during handling was inevitable.

In addition, when the folded book is aligned in the same direction, the back bag part overlaps and becomes bulky. When setting, there was a problem that it was necessary to return to the original direction.

The present invention is intended to solve such a problem, and an object of the present invention is to bind a printing book coming out of a printing process without causing damage and without manual labor. It is intended to provide a method and a device for feeding to a machine.

[Means for Solving the Problems] In order to achieve the above object, a method for supplying a bookbinding machine to a bookbinding machine according to the present invention is characterized in that a predetermined number of bookbindings coming out of a printing process are accumulated in the same direction. After forming the large bundle, the large bundle is stored in a transport cassette, and then the transport cassette is transported to a location adjacent to the bookbinding machine, and the large bundle in the transport cassette is taken out from the transport cassette. It is characterized by being supplied to.

In addition, the supply device of the present invention includes a unit that forms a large bundle by stacking a predetermined number of prints from the printing process in the same direction, a unit that stores the large bundle in a transport cassette, Means for transporting the cassette to a location adjacent to the bookbinding machine, removing the large bundle from the transport cassette, and supplying the large bundle to a feeder of the bookbinding machine.

[Operation] In the method and apparatus for supplying a bookbinding book to a bookbinding machine configured as described above, the printing books continuously discharged from the printing process are first formed into a large bundle in the same direction, and then are transported. It is stored in a cassette. Then, after the cassette is conveyed to a location adjacent to the bookbinding machine, a large bundle of prints is taken out of the cassette and set in a feeder of the bookbinding machine.

[Examples] Hereinafter, the present invention will be described based on examples shown in the drawings.

First, a description will be given of a process of stacking a large number of print books coming out of the printing process in the same orientation in a predetermined number. FIGS. 1A to 1E show this step.

In FIG. 1 (a), reference numeral s indicates a book which is discharged in a folded state from a rotary press or which comes out through a folding machine after being printed on a sheet-fed printing press. . As shown in the figure, the print book s is continuously discharged while being placed on a belt conveyor 11 of a rotary press or a folding machine,
It is accumulated on the elevator 12 at the accumulation position. Since the printed book s is a signature and has a back bag on one side, if a large number of copies are accumulated, the back bag portions overlap and easily collapse. Let it be t. 13
Is a cut-off plate, which is lowered when a predetermined number of prints s pass, and stops the flow of the prints s for a short time. Then, a small bundle t composed of a predetermined number of copies s
The elevator 12 with the lowers in this short time,
Instead of this, the skewer blade 14 extends. When the skewer blade 14 is extended, the cut-off plate 13 rises and the printing book s flows out again, and starts to accumulate on the skewer blade 14. On the other hand, the elevating platform 12 is lowered to the extruding position, and then pushed rightward by the extruding plate 16 operated by the small bundle conveying cylinder 15 to reach the lifting platform 21 which is the starting position of the next large bundle forming step. Be transported. Thereafter, the elevating platform 12 returns to the stacking position, and at the same time, the skewer blade 14 is retracted, and the printing books s accumulated on the skewer blade 14 are replaced on the elevating platform 12, and a predetermined number of copies are obtained from above. Until the book s is collected. By repeating this series of operations, small bundles t accumulated to such an extent that they do not collapse during movement are sequentially formed and sent to the next large bundle forming step.
