Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention is suitable for use in extracting a part of a book from a continuous book transport line such as a delivery section for discharging a book from a rotary printing press. Unprinted book extracting device.

[Conventional technology]

In a rotary printing machine or the like, the printing paper of the printing machine is cut and folded to form a book, which is discharged to the next step by a conveyor. In the delivery section that discharges the copybook,
It is necessary to pull out the defective part or the inspection book from the continuously ejected books, which is conventionally done manually by an operator.

[Problems to be Solved by the Invention]

However, in such a conventional method, it is necessary for a worker to be attached to each extraction, which is a major obstacle to unmanned operation of a printing machine or the like. As a method of coping with this, it is conceivable to install a commercially available sampling device, but for that purpose, it is necessary to remodel the book transport line drastically.
There was a problem that it could not be modified or installed if the space was small.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a print take-out device having a simple structure that can be easily attached to an existing print feed line.

[Means for Solving the Problems]

In order to achieve the above object, the present invention provides a push-up roller movably so as to push up a printed book from below a carrying conveyor for carrying a printed book in a delivery section of a rotary printing machine and above the carrying conveyor. Is provided with a feed roller that nips and sends the print book between the raised push-up roller and a discharge unit that discharges the print book sent by the feed roller. Further, downstream of the push-up roller,
A guide device is provided so that the end on the push-up roller side in the same direction as the transfer conveyor moves up and down in conjunction with the vertical movement of the push-up roller, and the guide means is provided so that the push-up roller is located below the transfer conveyor. However, when the push-up roller rises, the end on the push-up roller side moves upwards above the transport conveyor in conjunction with the rise of the push-up roller, In this structure, a slope having a downward slope is formed from the vicinity of the push-up roller at the elevated position toward the conveyor.

[Action]

In the apparatus having the above-mentioned configuration, the push-up roller and the guide device are usually located at the lower standby position where there is no hindrance to the transfer of the book by the transfer conveyor. When necessary, the push-up roller is projected upward from below the transport conveyor while the print conveyor is continuously transported by the transport conveyor. As a result, a part of the printed book is pushed up from the conveyor by the push-up roller, then nipped by the feed roller and the push-up roller, sent out to the discharging means, and taken out to a predetermined position by the discharging means. At this time, the peripheral speed of the feed roller should be set faster than the transfer speed of the transfer conveyor.
This is suitable for removing a printed book. By the way, if the peripheral speed of the feed roller is made higher than the transfer speed of the transfer conveyor,
Among the print sheets sent by the nip between the push-up roller and the feed roller, the print sheet before being sent to the discharging means is sent on the transport conveyor at a speed higher than the transport speed of the transport conveyor, overtaking the previous print sheet. In some cases, the wrap may be reversed, and if the cup is reversed in this way, the binding form may be unfavorable due to the folding of the book in the binding machine. However, in the present invention, since the push-up roller side of the guide device rises in conjunction with the rise of the push-up roller and forms the slope of the descending slope from the vicinity of the push-up roller in the raised position toward the conveyor, it is nipped and sent. This slope causes the previous copy of the incoming copy to move forward quickly and not be overtaken by the subsequent copy. In this way, it is possible to prevent the wrap from being reversed and causing a packaging defect when binding. After pulling out a specified book by the nip between the push-up roller and the feed roller and the ejecting means, the push-up roller and the guide device are returned to the original state to return to the original state, and the normal convey of the book is performed by the conveyor. Be seen.

Since the part of the book 35 that is sent toward the push-up roller 7 on the belt 2a is in an overlapped state, the print book 35 is lifted by the rise of the push-up roller 7 and sent to the discharge conveyor 23. When the printing is started, subsequent printing sheets are also supplied to the nip portion of the push-up roller 7 and the feed roller 11, and are sequentially sent out onto the discharge conveyor 23. Here, since the speed of the feed roller 11 is set to be higher than the transfer speed of the transfer conveyor 2 and the speed of the discharge conveyor 23 is set to be higher than the speed of the feed roller 11, the picked-up copy is halfway. It can be pulled out without clogging. Further, since the feed roller 11 is provided with the one-way clutch 13, there is no problem even if the discharging conveyor 23 is set to a higher speed than the feed roller 11. The printed sheets on the discharging conveyor 23 are stored in the boxes 31A and 31B by the discharging slope 30. At this time, the movable plate 33 at the lower end of the discharging slope 30 is switched depending on whether the extracted copy is a defective copy or a sample copy for inspection, and the extracted copy 35 is placed in the desired box 31A or Store in 31B.

When the necessary removal of the printing plate 35 is completed, the push-up roller 7 is lowered below the belt 2a as shown in FIG. 5C, and returns to the normal state.
