DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bookbinding line transfer device for transferring a booklet discharged from a bookbinding machine to a cutting machine.

[0002]

2. Description of the Related Art Paper printed by a printing machine or a copying machine (a bundle of sheets and a cover) is carried into a binding machine via a paper supply device and subjected to a predetermined binding process. As the binding machine, a bookbinding machine that performs a perfect binding process and a paper binding machine that performs a binding process using a wire or a thread are used. Generally, a binding machine is used for a thick bundle of paper for one book.
If the sheet is relatively thin, bookbinding is performed using a paper binding machine.

[0003] The perfect binding process by the bookbinding machine is a milling process of aligning a bundle of sheets of paper, clamping the bundle with a clamper, flushing the back surface of the bundle, and cutting with a milling cutter, and a subsequent gluing process using hot melt glue. After these processes, a process of attaching a cover using a nip plate is performed. The booklet bound by the bookbinding machine is conveyed by a conveyor and is trimmed by a trimming machine.

FIG. 3 is a schematic plan view showing an example of a bookbinding line in which a booklet bound by a bookbinding machine is conveyed to a trimming machine and finish trimming is performed. In FIG. 3, reference numeral 1 denotes a bookbinding machine, 2 denotes a discharge unit of the bookbinding machine, 3 denotes a booklet bound by the bookbinding machine 1, 4 denotes a discharge conveyor of the booklet 3, and 5 denotes a bookbinding block forming apparatus. The bookbinding block forming apparatus 5 stacks the required number of booklets 3 and presses the obtained bookbinding block 3a with a press device so that the bookbinding block 3a can be stably transported.
The transport direction of a is changed.

[0005] The bookbinding block 3a conveyed from the bookbinding block forming apparatus 5 includes first and second connecting devices 6a and 6b.
The material is carried out to the conveyor 7 through the b. The first connection device 6a is constituted by a lifter, and lifts the placed bookbinding block 3a to the plane of the conveyor 7 arranged above the bookbinding block forming device 5. Reference numeral 8 denotes a driving device of the conveyor 7 using, for example, a three-phase induction motor, and reference numeral 9 denotes a speed control device of the driving device 8 provided with an inverter or the like. The speed control device 9 receives the input control signal Ca
, The input voltage Cb is applied to the three-phase induction motor by controlling the frequency or voltage to a predetermined value, and the speed is controlled.

[0006] Reference numeral 10 denotes a direction changing device which changes the conveying direction of the bookbinding block 3a conveyed from the conveyer 7 by 90 degrees and discharges it to the unloading conveyer 11. Reference numeral 12 denotes a three-way cutting machine connected to the unloading conveyor 11, and a bookbinding block 3a.
Finish cutting out the other three sides, leaving the back side where the glue is attached. Reference numeral 13 denotes an accumulation unit of the bookbinding block 3a after cutting.

A booklet bound by a bookbinding machine has hot-melt glue adhered to the back surface when it is glued. If the attached glue is finished in a semi-dry state and cut by a cutting machine, the required bookbinding strength cannot be obtained, so take a certain amount of time on the bookbinding line until it is transported from the bookbinding machine to the cutting machine. The glue is hardened. For this purpose, the length L of the transport conveyor 7 is extended or a turn-back portion is provided to increase the transport distance by the transport conveyor, and the transport time of the bound booklet by the transport conveyor is adjusted. It is conceivable that the glue adhered to the surface is hardened by natural cooling.

[0008]

However, in a bookbinding machine for small lots, which targets several thousand booklets, it is required to reduce the space of the bookbinding line from the bookbinding machine to the cutting machine. For this reason, as described above, the adhesive attached to the back surface of the bound booklet is hardened by natural cooling by extending the length of the transport conveyor or providing the folded portion, as the installation space of the transport conveyor increases. There was a problem that implementation was difficult. Further, if the transport speed of the bound booklet is adjusted by lowering the transport speed of the transport conveyor, there is a problem that the processing efficiency of the bookbinding line is reduced.

In view of the above problems, the present invention provides a time required for hardening the glue adhered to the back surface of a booklet glued by a bookbinding machine by natural cooling, and
An object of the present invention is to provide a transfer apparatus for a bookbinding line that does not reduce the processing efficiency of the bookbinding line.

[0010]

SUMMARY OF THE INVENTION The object of the present invention is to provide a bookbinding line transfer device for transferring a bookbinding block formed by stacking a predetermined number of booklets glued by a bookbinding machine to a cutting machine. A sorting device that sorts and binds the bookbinding blocks conveyed in one row in a plurality of rows in the conveying direction, and a conveying conveyor that is connected to the sorting device and that is driven at a lower speed than the conveying speed of the sorting device. This is achieved by a configuration in which the transport time of the bookbinding blocks sorted by the sorting device and placed in a plurality of rows on the transport conveyor corresponds to the time required for the glue adhering to the back of the booklet to harden by natural cooling. You.

With this configuration, the conveyor is connected to the sorting device that sorts the bookbinding blocks into a plurality of rows. Therefore, the space for installing the conveyor provided on the bookbinding line is not increased so much. While the bookbinding block is transported by the transport conveyor, the glue adhering to the back of the booklet can be hardened by natural cooling. Further, since the bookbinding blocks are transported in a plurality of rows by the transport conveyor, even if the transport speed of the transport conveyor is reduced, the processing efficiency of the bookbinding line is not reduced as compared with the conventional one.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a bookbinding line transfer device according to the present invention will be described below with reference to FIGS. FIG. 1 is a schematic plan view showing an example of a bookbinding line according to the present invention. In FIG. 1, the same portions as those in the conventional example of FIG. 3 are denoted by the same reference numerals, and detailed description will be omitted.
In the present invention, a sorting device 14 for sorting the bookbinding blocks 3a into row A and row B is connected to the lifter 6a. In addition, a two-row conveyor 15 that transports the bookbinding blocks 3 a in two rows, row A and row B, is connected to the sorting device 14.

FIG. 2 is a schematic perspective view of the sorting device 14. As shown in FIG. 2, the sorting device 14 includes first, second, and third feed belts 14a, 14b, and 14c, a moving plate 14d, a pusher 14e, a support base 14f, first and second feed belts.
Are constituted by the mounting members 14g and 14h. When the pusher 14e operates, the support 14f connected to the tip of the pusher 14e moves, and the movable plate 14d attached to the support 14f via the first and second attachment members 14g and 14h is viewed in the direction X1. , X2 direction.

With the moving plate 14d moving in the direction of arrow X1, the bookbinding block 3a raised to the surface of the first feed belt 14a of the sorting device 14 by the lifter 6a.
Are the second and third feed belts 14b and 14c in the row A direction.
And is conveyed to the two-row conveyor 15 via. The bookbinding block 3a raised to the surface of the first feed belt 14a of the sorting device 14 by the lifter 6a at the next timing.
When the moving plate 14d moves in the direction of arrow X2, the moving plate 14d is pulled in parallel to the row B position on the feed belt 14a.

The moving plate 14d moves in the direction of arrow X2 and stops at an intermediate position between the first to third feed belts 14a to 14c, and the bookbinding block 3a located at the row B moves laterally to the row A. Acts as a partition to prevent
The bookbinding block 3a at the row position is conveyed to the two-row conveyor 15 in the B-row direction via the second and third feed belts 14b and 14c.

The bookbinding block 3a discharged from the bookbinding machine 1 and continuously raised to the surface of the first feed belt 14a of the sorting device 14 by the lifter 6a via the first direction changing device 5 is sorted. The pusher 14e of the device 14 operates to alternately move the moving plate 14d with the arrow X.
By moving in the X1 and X2 directions, the two rows of the row A and the row B are placed on the two row conveyor 15.

Here, the transfer speed of the two-row transfer conveyor 15 depends on the first to third positions of the bookbinding block 3a of the sorting device 14.
Is set lower than the transport speed of the feed belts 14a to 14c. For this reason, the two-row conveyor 15
Bookbinding block 3a placed in two rows, row and row B
Is transported in the direction of the direction change device 10 in a state where the front and rear intervals in the transport direction are narrowed according to the speed difference between the transport speed of the sorting device 14 and the transport speed of the two-row transport conveyor 15.

When the length of the two-row conveyor 15 is set to L, which is the same as that of the conventional example shown in FIG. 3, the two-row conveyor 15 having two rows A and B has a larger dimension in the width direction. Since the bookbinding blocks 3a are placed on the second row, the number of bookbinding blocks 3a conveyed by the two-row conveyor 15 can be doubled as compared with the conventional example when the conveying speed is the same. At this time, the transfer speed of the two-row transfer conveyor 15 is lower than the transfer speed of the bookbinding block 3a of the sorting device 14, and the time required for naturally cooling the glue adhering to the back surface of the bound booklet. It is set so that it can be obtained.

The length L of the double-row conveyor 15 is a known value, and the time required for naturally cooling the glue adhering to the back surface of the bound booklet 3 is obtained by actual measurement. The transport speed of the two-row transport conveyor 15 is set using these known values, and the number of rotations of the driving device 8 is controlled.

As described above, in the examples shown in FIGS. 1 and 2, the double-row conveyor 15 uses the bookbinding block without increasing the space of the entire bookbinding line by only slightly increasing the width of the conveyor. While the 3a is being conveyed, the glue adhering to the back surface of the bound booklet can be naturally cooled. Further, since the bookbinding blocks 3a are placed in a plurality of rows and transported by the two-row transport conveyor 15, even if the transport speed of the two-row transport conveyor 15 is reduced, the processing efficiency of the bookbinding line is reduced as compared with the conventional example. Can be suppressed.

The direction changing device 10 takes out, for example, a feed belt connected to the double-row conveyor 15 and bookbinding blocks 3a conveyed by the double-row conveyor 15 from the feed belt alternately in row A and row B. A take-out unit that changes the direction by 90 degrees and carries out the product is provided. The take-out unit may be provided with a delivery plate on a conveyor that reciprocates in the carry-out direction.

[0022]

As described above, in the present invention,
Since the conveyor is connected to the sorting device that sorts the bookbinding blocks into multiple rows, the booklet can be transferred while the bookbinding blocks are being conveyed by the conveyor without significantly increasing the installation space of the conveyor provided on the bookbinding line. The glue adhering to the back surface can be hardened by natural cooling. Further, since the bookbinding blocks are transported in a plurality of rows by the transport conveyor, even if the transport speed of the transport conveyor is reduced, the processing efficiency of the bookbinding line is not reduced as compared with the conventional one.
