Description

[Detailed description of the invention] "Industrial application field" This invention is about a device that stacks a certain number of printed signatures in a counter stacker to form a bundle of signatures, and then presses and binds the bundles. This invention relates to an improvement in a paper feeding device that applies paper to the upper and lower surfaces of a bundle of signatures.

``Prior art'' When a signature printed by a rotary press is cut and folded into a predetermined size by a folding machine,
First, a certain number of sheets are piled up by a counter stacker to form a bundle of signatures.Next, on the transfer route from the counter stacker to a binding machine, the paper is applied to the top and bottom of the bundle of signatures, and then it is pressed and the paper is pressed. Generally, they are tied together in a state. The purpose of applying this paper to the top and bottom of the bundle of signatures is to prevent damage during binding, and to prevent damage and dirt from occurring during subsequent transport. be. The method conventionally used in devices that supply paper to the top and bottom surfaces of a stack of signatures is to suck up the paper using separate suction tools for the bottom paper and the top paper, respectively.
The lower sheet was sandwiched between two rollers and sent upwards, applying it to the bundle of signatures as it progressed along the transport path, while the upper sheet was applied to the top surface of the bundle of signatures on the binding machine by the paper transfer device. .

FIGS. 9 and 10 show an embodiment of the conventional upper and lower paper supply and binding device. That is, the ninth
The figure is an explanatory view of the operation of an embodiment of a conventional base paper feeding device. In the figure, 101 is a base paper receiving plate on which the base paper S' is placed, and it is raised by a receiving plate lifting device 102. , descending is possible. Reference numeral 103 is a suction tool for sucking and lifting the bottom paper S', and can be moved up and down by the operation of a cylinder 104. A pressure roller 105 comes into pressure contact with a charge roller 106 by the operation of a cylinder 107, and pinches the bottom paper S'. 108, 108 are free rollers on the transfer path, and P is a bundle of signatures. Next, to explain the operation of the bottom paper supply device constructed as described above, first, the cylinder 104 is operated to lower the suction tool 103 downward, and the bottom paper S' is sucked by the suction tool 103. Then, by operating the cylinder 104, the suction tool 103 is raised upward, and the suctioned paper is exposed between the charge roller 106 and the pressure roller 105. Next, the cylinder 107 is operated to bring the pressure roller 105 into pressure contact with the charge roller 106.
S' is pinched, the charge roller 106 is rotated to slightly feed out the base paper S', and the suction of the suction tool is stopped. When the stack of signatures P approaches, the charge roller 106 is rotated at an appropriate timing.
The bottom paper S' is sent upward and is moved to the free roller 108,
It is fed while hitting the bottom surface of the bundle of signatures P that has just advanced after coming out between 108 and 108. When the lower sheet S' is consumed and its height decreases, the receiving plate elevating device 102 is activated and the sheet receiving plate 101 is raised, so that there is no problem with subsequent paper feeding.

On the other hand, FIG. 10 is an explanatory diagram of the operation of an embodiment of a conventional overlapping paper feeding device. In the figure, 109 is the paper receiving plate on which the upper paper S'' is placed.

In addition, 6 in the figure is a binding machine. To explain this overlay paper supply device, first, the press device 112 is lowered, the suction device 111 is brought into close contact with the overlay sheet S'', and the press device 112 is raised.Next, the press device 112 is raised. The transfer device 113 is actuated by the signal that P is conveyed onto the binding machine 6, and the transfer device 113 moves to the right, and the upper paper that is sucked by the suction tool 111
When S'' is also fed to the right and is above the signature bundle P, the press device 112 is lowered, and the upper sheet S'' is moved to the top of the signature bundle P.
applied on top of. When the upper sheet S'' is consumed and its height becomes lower, the receiving plate elevating device 110 is activated and the upper sheet receiving plate 109 is raised, so that there is no problem with subsequent paper feeding.
As described above, after the top sheet S and the bottom sheet S' are applied to the signature bundle P, the signature bundle P is pressed by the press device and bundled in this state by the binding machine 6.

``Problems to be solved by the invention'' The conventional upper and lower stacking paper supply device for a stack of signatures is a conventional method in which devices for lower stacking paper and upper stacking paper are installed separately in a row, and each is applied separately and sequentially. According to this method, two sets of paper feeding devices are required, and the equipment such as a paper transfer device and a device for lifting a paper receiving plate as the paper is consumed is complicated and costs a lot of money. Furthermore, even if paper runs low, it is not possible to replenish it mid-way, and when it runs out, the machine must be stopped and replenished. Since there are two locations where this is necessary, it becomes necessary to stack as many as possible at one time, which makes the device occupy a large space and become complex.

If you run out of paper as mentioned above, you will have to stop the machine and replenish paper, but it is not possible to stop the rotary press while it is running.
When you run out of paper, compress it without the paper, tie it up, untie it manually, wrap it again, and use a separate bundling machine or the machine's bundling machine to tie it again. This requires the operation of tying, which is a huge waste of effort.

``Means for Solving the Problems'' This invention attempts to eliminate the above-mentioned drawbacks of the conventional technology, and is designed to integrate a paper feeding device that feeds the paper one sheet at a time using rubber rollers, and a lifting device for compression. A paper transfer device assembled to the paper transfer device, a base paper supply device that feeds the base paper from below in the middle of the signature bundle transport route, and a signature bundle installed at the tip of the signature bundle transport route. In the upper and lower paper supply and bundling device for a signature bundle, the device includes a signature bundle transfer device that transports the signature bundle to a binding position, a press device that compresses the signature bundle at the binding position, and a signature bundle binding device. The above-mentioned paper feeding device is installed on the upper part of a frame that is set up from the machine body, and consists of a paper loading shelf and a paper feeding rubber roller that is driven intermittently. The above-mentioned paper transport device is a pair of opposing endless belts integrally attached to a compression lifting device that is attached to the frame so as to be able to rise and fall freely, and has a drive mechanism. The paper is held and transferred between the endless belts. They are arranged facing each other so as to have a driving force, and before the bundle of signatures is transferred to the bundling position, the rollers are reversely rotated to receive the paper from the paper transport device.
The press device, which is configured to be sent out from below as a base paper by normal rotation of the rollers and which compresses the signature bundle, is transferred to the bundling position by the signature bundle transfer device, and at this position, the elevating device for compressing the signature bundle is lowered. A press plate that can move up and down and a biasing spring are installed in the center of a beam installed between the frames of the machine to transfer the bundle of signatures to the paper transfer device. During the process, both the upper and lower sheets are fed from the paper transport device and the bottom paper feeder at appropriate timings, and after the transfer is stopped at a predetermined position, they are compressed by a press device and folded by a binding device. By bundling the stacks, it is possible to supply top paper and bottom paper with one feeding device, which is simpler than conventional equipment.
Furthermore, the paper feeding device does not move up and down, and the present invention provides a top and bottom paper supply and binding device for a stack of signatures, which allows paper to be replenished even when the machine is in operation when the paper runs out.

"The action of invention" Next, the effect of this invention will be explained.

In FIG. 6, when the paper transfer device 2 is in the middle of the stroke of the cylinder 35, when the cylinder 35 is operated in the upward direction, the cylinder 3
The upper end of the beam 5 is connected to the beam 8 by a pin 34 and a bracket 33, so that the beam 8 rises.
The pinion gears 37 at both left and right ends of the beam 8 are engaged with the racks 38 and move up and down, so the beam 8 rises at the same height on both sides. There are guide rollers 39 above and below the bracket 33, which run in guide grooves 40 so that they do not swing back and forth. When the beam rises, the paper transport device 2 and press device 5 fixed to the beam 8 also rise and reach the uppermost end.

Next, in FIG. 4, when the motor M ₁ is activated and the paper feeding rubber roller 10 and the auxiliary rubber roller 11 are rotated by driving the chain 15 and the belt 16, the paper S placed on the paper stack number 9 is rotated.
The paper is fed out one by one while being sandwiched between the feed rubber roller 10 and the rubber plate 12, passes over the guide roller 17, and is seen between the guide rollers 19 and 20.

On the other hand, when the motor _M2 of the paper transfer device 2 is activated to drive the chain 30 in the direction of the arrow, the guide roller 19 rotates while being in pressure contact with the guide roller 20, and the holding base end roller 21
and 22, and the holding and guiding rollers 23 and 24 rotate while being pressed against each other, so that the polycord belt 31 is fed in the direction of the arrow. Now, among the sheets S sent out from the paper feeder 1, the one used as the bottom sheet is S', and the one used as the top sheet is S''.The bottom sheet seen between the guide rollers 19 and 20 When S' is caught between the guide rollers 19 and 20, the cylinder 35 is actuated and the paper transport device 2 starts to descend, but the lower paper S' continues to be held between the holding base rollers 21 and 22. The paper is then fed while being sandwiched between the polycord belt 31. After the bottom paper S' is sandwiched between the guide rollers 19 and 20, the feeding rubber roller 10 and the auxiliary rubber roller 11 are driven. Even if the paper feeding rubber roller 10 and the auxiliary rubber roller 11 are stopped,
has a built-in one-way clutch, so
The bottom paper S' is fed while being sandwiched between the guide rollers 19 and 20 and the polycord belt 31, and hangs down from between the holding end rollers 23 and 24, and the paper transport device 2 is moved as shown in FIG. Stop at the position shown in Figure 8. Next, it will be explained with reference to FIG. Before the paper transfer device 2 does not reach the lower end, the cylinder 51 of the lower paper feed device 3 is actuated so that the guide plate 47 is erected on the transfer path surface as shown in FIG. Further, the chain 45 is driven as shown by the arrow in FIG. 8 by the operation of the motor _M3 , and the lower paper supply roller and the pressing roller 43 are rotated. After the paper transfer device 2 has descended to the position shown in FIG. 8, the lower paper S' is further guided by the guide plate 47 and sent downward, and is sandwiched between the lower paper supply roller 42 and the presser roller 43. When the upper side of the lower sheet S' reaches the vicinity of the transport path surface, the rotation of the lower sheet supply roller 42 is stopped and the sheet is temporarily on standby. After the bottom paper S' is caught between the bottom paper supply roller 42 and the presser roller 43, the paper transport device 2 moves upward, but since the holding end roller 23 has a built-in one-way latch, The paper S' can be fed downward by being sandwiched between the base paper supply roller 42 and the presser roller 43. Next, the guide plate 47 operates the cylinder 51 to bring it into the state shown in FIG. 7, so that the guide plate 47 is on the same surface as the transfer path surface of the signature bundle P. After the paper transport device 2, which is moving upward, reaches the top as shown in Fig. 1, feed the upper paper S'' in the same manner as before and move it to the paper transport device 2.
The paper transport device 2 descends while feeding the paper. Since the height of the signature bundle P is determined in advance, the holding tip rollers 23, 2 at the lower end of the paper transport device 2
4 approaches the height of the signature bundle P, the descent stops,
The top paper S'' is slightly protruded from the lower end of the paper transfer device 2, and paper feeding is stopped and it is temporarily on standby.The signature bundle P is sent by the signature bundle transfer device 4 and transferred to the conveyor device 54 of the binding machine 6. At the timing when the paper is about to be transferred, the bottom paper supply roller 42 is reversed as shown in FIG. 2 works as a top sheet feeding device to feed out the top sheet S'' and apply it to the top surface of the signature bundle P. Since the advancing speed of the signature bundle P and the unwinding speed of the bottom sheet S' and the top sheet S'' are the same, the sheets are placed on the binding machine 6 while touching the top and bottom surfaces of the signature bundle P. (No. (See Figure 3).

The completed signature bundle P is compressed by a press device 5, and in this state is bound by a binding machine 6. Even if the height of the stack of signatures P changes, since the cylinder 35 uses a rod grip type air cylinder, it can be stopped at a desired position. The series of actions is
Control equipment such as photoelectric switches eliminates wasted time and is performed continuously.

It consists of a paper loading shelf and a paper feed rubber roller that is driven intermittently, and is configured so that the paper feeding rubber roller feeds sheets one by one from the paper loading shelf, and the paper transport device can be raised and lowered along with the frame. It is a pair of opposing endless belts that are integrally attached to the compression lifting device attached to the machine, and has a drive mechanism, so that the paper from the paper feeder is held and transferred between the endless belts.

A press that compresses the bundle of signatures by receiving the paper from the paper transport device by rotating the rollers in reverse before the bundle of signatures is transferred to the position, and sending out the paper from below as the bottom paper by rotating the rollers in the normal direction. The device is transported to a bundling position by a signature bundle transfer device, and at this position, the signature bundles that have been transferred by lowering of the signature bundle compression lifting device are placed vertically in the center of a beam installed between the frames of the machine body. It is configured by providing a movable press plate and a biasing spring, and when the bundle of signatures is being transferred to the paper transfer device, the paper transfer device and the lower paper feed device are pressed both above and below at an appropriate timing. After supplying the paper, the paper is transferred and stopped at a predetermined position, compressed by a press device, and the bundle of signatures is bound by a binding device.

Therefore, it is possible to supply the top paper and the bottom paper with one feeding device, which can be simpler than conventional devices. Furthermore, since the paper feeding device does not move up and down, even if the paper runs out, it is possible to replenish the paper without stopping the machine even if the machine is in operation.
