Description

  The present invention relates to a conveyance device that conveys a booklet discharged from a perfect binding machine to a cutting machine.

The body that is being transported is inserted and clamped in a clamper that moves around, and as the clamper moves, the back of the body that is clamped by the clamper is trimmed flush with a milling cutter, and hot on the back of the trimmed body 2. Description of the Related Art A perfect binding bookbinding machine that performs pasting with melt glue and then attaches a cover to the back of the glued body is known. In addition, a booklet bound by a perfect binding machine is usually finished by trimming the three sides of the edge, top, and ground with a three-way cutting machine.

In order to carry out a series of processes from bookbinding to three-sided cutting without any hassle, the bookbinding machine and the three-way cutting machine are connected by a booklet transport device, and the booklet ejected from the booklet binding device is sent to the three-way cutting machine by this booklet transporting device. May be sent. FIG. 5 is a schematic plan view showing an example of a bookbinding system in which a booklet with a cover attached by the perfect binding machine in this case is transported to a three-sided cutting machine to perform finish cutting. In FIG. 5, 1 is a perfect binding machine, 2 is a booklet discharge conveyor of the perfect binding machine, 3 is a lifting platform, 4 is a first transport conveyor, 5 is a transport direction changing conveyor, and 6 is a second transport conveyor. , 7 is a three-way cutting machine.

In this bookbinding system, the booklet discharged from the bookbinding machine 1 to the booklet discharge conveyor 2 is placed on the lifting platform 3 with the back as the head, and a predetermined number (for example, two) of booklets are stacked. 1 is sent out onto one conveyor 4. A predetermined number of stacked booklets conveyed by the first conveyor 4 are moved to the conveyance direction conversion conveyor 5, where the conveyance direction of the booklet is changed by 90 degrees, moved to the second conveyor 6, and the second It is conveyed by the conveyance conveyor 6 to the carry-in entrance of the three-way cutting machine 7. The booklet conveyed to the carry-in port of the three-way cutting machine 7 is moved and positioned inside the three-sided cutting machine 7 surrounded by the small edge cutting blade 7a and the top / ground cutting blades 7b and 7c, and then the small edge cutting blade 7a, By driving the top and ground cutting blades 7b and 7c, the booklet is cut out in three directions, the top, the top, and the ground.

By the way, the back of the booklet discharged from the saddle stitching machine is coated with a semi-cured hot melt glue, and cannot be cut in this state. The glue should be almost completely cured. For this purpose, in the bookbinding system described above, a predetermined number of booklets discharged from the saddle stitching bookbinding machine (thickness that can be cut, for example, two books) are stacked and sent onto the first conveyor 4. By this stacking, the booklet transport speed by the first transport conveyor 4, the transport direction changing conveyor 5 and the second transport conveyor 6 can be reduced as compared with the case of transporting the booklets without stacking them. The distance can be shortened.

Then, in the speed reduction, the number p of booklets stacked, the length x in the booklet transport direction, the interval A between booklets on the transport conveyor, the maximum number of cuts per hour M, and the operation rate e of the perfect binding machine , P · e · M is determined by the equation e · M (x + A) / 3600 (mm / sec) on condition that the maximum number of bookbindings of the perfect binding bookbinding machine is n or more, and the conveyor is moved at the determined speed. I try to drive it.

  By the way, in the bookbinding system as described above, there is a case where bookbinding is performed by manually inserting the body into the clamper. In this case, the bookbinding speed varies, the bookbinding body is prepared at a position where it can be easily inserted, and the operation rate of the saddle stitching machine is not stable, and it is difficult to adjust the operation rate. The speed of the conveyer cannot be obtained by the equation, and the speed of the conveyer must be adjusted to the maximum speed to be manually fed. For this reason, a conveyor having a long conveying distance is inevitably required, which increases the size of the entire bookbinding system.

The problem to be solved by the present invention is to enable manual binding with a short conveyor to eliminate such a problem in a bookbinding system in which a perfect binding and cutting machine are connected by a conveyor.

In order to solve the above-described problems, the present invention includes a lifting platform that stacks and sends out a predetermined number of booklets discharged from the saddle stitch binding machine, and a conveyor that receives the booklets sent from the lifting platform and transports them to a cutting machine. In the booklet transport apparatus for bookbinding system provided, a booklet dimension input means for inputting a dimension in the transport direction of the booklet transported by the conveyor, an inter-booklet input means for inputting a booklet interval transported by the transport conveyor, and the booklet dimensions Calculation means for calculating the operation time of the conveyor based on input values inputted by the input means and the input means between the booklets, a memory for storing the calculation result of the calculation means, and the number of booklets stacked on the lifting platform A booklet number setting means for setting, and each time the number of booklets set in the booklet number setting means is stacked, the transport controller stored in the memory is stored. The conveyor is driven during the operation time of the booklet, and the booklet sent on the conveyor is sequentially moved by the booklet dimension inputted by the booklet dimension input means and the dimension inputted by the inter-booklet input means. And

In the present invention, a predetermined number of booklets discharged from the saddle stitching machine are stacked, and the booklet discharged from the saddle stitching machine is intermittently fed, so that the number of booklets discharged from the saddle stitching machine is larger than the transport distance until the booklet reaches the cutting machine. Time, that is, a long cooling time can be ensured, whereby the transport distance by the transport conveyor can be shortened even when manual bookbinding is performed.

It is a block diagram of the operation control apparatus of the booklet conveyance apparatus for bookbinding systems which concerns on the Example of this invention. It is a display screen figure of the operation panel of the operation control apparatus shown in FIG. It is operation | movement explanatory drawing of the operation control apparatus shown in FIG. It is operation | movement explanatory drawing of the booklet conveyance apparatus in the operation control apparatus shown in FIG. It is a top view of a bookbinding system.

Hereinafter, a booklet conveying apparatus for a bookbinding system according to an embodiment of the present invention will be described with reference to the drawings. As for the configuration of the bookbinding system in which the binding machine and the cutting machine are connected by a conveyor, the booklet discharged from the bookbinding machine 1 to the booklet discharge conveyor 2 moves up and down with the back at the top. A predetermined number (for example, two) of booklets are stacked on the table 3 and sent out onto the first conveyor 4. A predetermined number of stacked booklets conveyed by the first conveyor 4 are moved to the conveyance direction conversion conveyor 5, where the conveyance direction of the booklet is changed by 90 degrees, moved to the second conveyor 6, and the second It is conveyed by the conveyance conveyor 6 to the carry-in entrance of the three-way cutting machine 7. The booklet conveyed to the carry-in port of the three-way cutting machine 7 is moved and positioned inside the three-sided cutting machine 7 surrounded by the small edge cutting blade 7a and the top / ground cutting blades 7b and 7c, and then the small edge cutting blade 7a, This is the same as the configuration in which the booklet cutting edge 7b, 7c is driven to cut out the booklet's small edge, top, and ground, and eject it.

Here, the transport direction changing conveyor 5 is used to change the direction of the booklet sent to the three-way cutting machine 7 and is not necessarily required. Therefore, the first transport conveyor 4 and the transport direction changing conveyor 5 are used. The second conveyor 6 is collectively referred to as a conveyor C. A sensor 3 a for detecting a booklet is installed at the entrance of the lift 3. Reference numeral 11 denotes an operation panel for inputting various setting values.

The booklet conveying apparatus for bookbinding system according to the present invention is provided with an operation control apparatus 8 shown in FIG. The operation control device 8 includes a CPU (Central Processing Unit) 9 and a memory 10 for storing calculation results and set values. As shown in FIG. 2, the booklet size (the dimension between the top and the bottom of the booklet, that is, the dimension in the direction in which it is conveyed by the conveyor C) 11a and the conveyor are discharged from the operation binding 11 in advance. The distance 11b between booklets on C is input. Note that the size of the booklet may be calculated in the operation control device 8 by inputting a sensor on a line through which the booklet passes as appropriate, and by inputting a detection signal of the sensor. You may make it acquire from.

When this dimension is input, the CPU 9 calculates (booklet size + interval between booklets + (acceleration time × set speed)) / set speed, and performs one step (one cycle) of the conveyor C shown in FIG. ) And the calculation result is stored in the memory 10. In the present embodiment, the number of booklets to be stacked on the lifting platform 3 is input from the operation panel 11 and 11c (FIG. 2), and the number of booklets is stored in the memory 10. The set speed referred to here is the speed at which the booklet is discharged from the elevator 3.

At the time of bookbinding, as shown in FIG. 3, the booklet ejected from the saddle stitch binding machine 1 and sent to the lifting platform 3 is detected by the sensor 3 a and sent to the CPU 9. In the CPU 9, the number of booklets sent from the sensor 3a is counted by a counter, and when the count value reaches the number of booklets stored in the memory 10, the booklets stacked on the lifting platform 3 are discharged to the conveyor C (shown in FIG. 1). This works when the booklet discharge motor is discharged to the conveyor C.), resets the counter. At the same time as the booklet is discharged to the conveyor C, the CPU 9 reads the operation time stored in the memory 10, starts the operation of the conveyor C as shown in FIG. 4, and stops the operation of the conveyor C when the operation time elapses. .

The booklet discharged to the conveyor C from the start to the stop of the operation of the conveyor C is located at a position separated from the size of the booklet and the distance between the booklets from the elevator 3, and at that position, the next elevator is moved up and down. Wait until the vehicle 3 is discharged. In this state, when a predetermined number of stacked booklets set on the lifting platform 3 are discharged to the conveyor C, the CPU 9 simultaneously reads the operation time stored in the memory 10 and starts the operation of the conveyor C. When has elapsed, the operation of the conveyor C is stopped. It waits until the next discharge from the elevator 3 at that position. In this case, the subsequent booklet is located at a position separated from the previous booklet by the distance between the booklets. Of course, if the interval between the booklets is set to 0, the subsequent booklet will continue without overlapping the previous booklet. Note that the interval between booklets is set to an appropriate size in consideration of cutting processing and the like. The booklet discharged from the perfect binding apparatus 1 by repeating the above operation is sequentially conveyed to the three-way cutting machine 7.
