Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a novel method for collating interleaf sheets onto a base sheet being conveyed.

The present invention provides an optimal interleaf paper collation method for sequentially collating interleaf sheets such as spines while feeding a constant number of stacked paper units such as booklets at intervals.

Conventionally, when collating the cover of a book that is being transported,
For example, as shown in Utility Model Publication No. 34-3710,
The cover is fed diagonally to the bottom surface of the book using a conveyor that runs diagonally from below the book, and at the end of the oblique conveyor for supplying the cover, the top of the front end of the book is overlapped with the top of the front end of the cover, and the top of the front end of the book is overlaid. The front edges of the front covers are aligned and the driving force of the diagonal conveyor for supplying the covers is used to transport them forward and collate them. In addition to the risk that some parts of the cover may slip and slide further forward, the fact that the cover is a single leaf and flexible is also a problem, as the weight of the book is placed on the cover and it becomes difficult to move. As a result, there is a drawback that proper collation cannot be achieved due to misalignment, inclination, or wrinkles.

In addition, since the covers are kept on standby on the diagonal conveyor, there is a risk of them slipping off, and it is difficult to set the timing between sending out from the standby position and loading the books, and the front edge of the covers overhangs excessively at the overlapping position. It is easy to cause deviation and wrinkles due to alignment.
In addition, the conveyor for conveying books has a wide gap between the front stage and the rear stage, and the front end of the oblique conveyor for supplying covers must be placed in the space, and an alignment device, etc. must be installed. The transport of books has to depend on rollers, etc., making the movement of books very unstable.If the books are unbound, they tend to be stacked misaligned, and there is a limit to the feeding speed. cormorant.

Furthermore, since the cover feeding device is installed in a hidden position below the book transport path, it is difficult to manage the feeding of the cover from above, and it is difficult to quickly deal with troubles that occur.

In general, the above conventional equipment requires several stages of conveyor equipment, multiple butting devices, etc., resulting in a complicated structure.
It has problems such as lack of reliability.

Therefore, the present invention solves the problems of the conventional collating device and provides a new method that allows interleaving sheets such as covers to be easily and reliably collated onto the bottom surface of base sheets of books etc. do.

The drawings show an example of an implementation mechanism of the present invention.

1 indicates a unit base paper that is conveyed along a fixed trajectory.

As mentioned above, the base paper is a book or a single sheet of paper loaded with a constant number of sheets.

Reference numeral 2 denotes a flat conveyance path constituted by a straight rail plate, and 3 a pusher which runs longitudinally within the conveyance path 2.

As is known, the pusher 3 is an endless driving body 4 such as a chain, which is provided so as to run in parallel below the conveyance path 2.
They are attached at regular intervals to the conveyance path 2, are inserted in the conveyance groove formed in the longitudinal direction of the conveyance path 2, and are made to protrude above the conveyance path 2.

The pusher 3 is preferably driven intermittently,
Non-stop driving may be used as long as each base sheet 1 has a conveying interval and speed that are compatible with the slip sheet supply timing described later.

The base paper 1 is conveyed forward along the conveyance path 2 while its rear end is propelled by the pusher 3 as described above. A slip sheet storage space 5 is provided in the path of the conveyance path 2 at a position below the conveyance path.

The interleaving paper storage space 5 is separated from the mother paper supporting surface of the conveyance path 2, that is, the conveyance path surface, by a rail plate 2a forming the conveyance path 2, and opens onto the conveyance path surface on the mother paper discharge side. 6 indicates a slot which is the opening thereof.

The interleaving paper is inserted into the interleaving paper storage space from the slot 6 before the base paper 1 reaches the slot 6.

FIG. 2 shows an example of the interleaving paper supply device. In the figure, reference numeral 7 denotes a rack for stocking interleaf sheets 8 provided above the conveyance path, and when the rack 7 is tilted forward, the interleaf sheets 8 loaded on the rack are regulated by a front stopper 9, and the rack is tilted forward. An interleaving paper extraction port 10 that opens downward is formed at the end.

Reference numeral 11 denotes a suction device for separating the end of the lowermost interleaving paper 8 from the interleaving paper extraction port 10 one by one at a constant cycle, and 12 the separated interleaving paper 8. A feed roll provided below the extraction port 10 that is reversely fed into the opening space of the storage space, 13 a slip paper feed belt provided extending from the feed roll, and 14 synchronized with the paper sorting operation of the suction member 11. This is a pull-out wheel that operates to pinch the paper end of the separated paper 8 between it and the paper feed roll 12, and forcibly guide the paper drawer toward the circumferential surface of the feed roll.

The figure shows an example in which a cam is used as a motion source for each of the above-mentioned elements, where 15 is a cam for timing operation of the suction element 11, and 16 is a cam for timing operation of the paper puller wheel 14.

The paper 8 separated by the suction member 11 is drawn out to the circumferential surface of the feed roll 12 by the pull-out wheel 14, and then is fed out toward the bottom dead center of the feed roll 12 while being held between the feed belts 13. ,
The end of the paper is turned over and fed toward the corresponding slot 6 at the feeding end.

The interleaving paper 8 has a feed roll 12 and a feed belt 13
The sheet is inserted into the interleaf storage space 5 at a position away from the sheet. In order to maintain the proper insertion position of the inserted slip paper 8, a slip paper stopper 17 is provided at the back of the slip paper storage space 5.

As a result of the above, the interleaf paper 8 is positioned below the conveyance path 2 and is kept on standby without interfering with the base paper 1.

In the standby state of the interleaf paper 8, the rear end of the base paper 1 is propelled by the pusher 3, and the base paper 1 is transported forward while being supported by the transport path 2.

In this way, the base paper 1 is conveyed onto the conveyance path 2 above the interleaving paper storage space 5, and the propelling action of the pusher 3 is placed in the non-interfering state at the position where the base paper 1 and the interleaf paper 8 correspond vertically. It also extends to the interleaf sheets 8 in the interleaf sheet storage space 5, and aligns the sheets by pressing the rear ends of both 1 and 8 with the shared pusher 3 in the non-interfering state. By the subsequent propulsion of the common pusher, the interleaving paper 1 is carried out from the opening of the interleaving paper storage space 5 onto the front conveyance path, and at the same time, the base paper is carried out onto the front conveyance path of the opening.

Along with this conveyance, the base paper 1 and the interleaf paper 8, whose relative positions for collation have already been set in a non-interfering state, are gradually overlapped on the conveyance path 2, and the entire length of the interleaf sheet 8 is brought out onto the conveyance path. In this position, the two are completely collated.

By repeating the above operations, collation of each unit base paper with the base paper 1 on top and the interleaf paper 8 on the bottom can be continuously obtained while the base paper 1 is being conveyed.

According to the present invention, it is possible to extremely easily and accurately collate interleaf sheets for each unit base sheet, and it is possible to rationalize and simplify the interleaf sheet collation mechanism and the book processing line.

That is, according to the present invention, the collation position of both sheets can be set in advance by pressing the common pusher in a non-interfering state before stacking the base paper on the interleaf paper and applying weight, and then the collating position of the two sheets can be set in advance by pressing the common pusher. Complete collation can be achieved by propulsion, which eliminates the problem of poor collation such as wrinkles, slanting, and misalignment of the leading edge of the interleaving paper, which is the case with the conventional method of stacking the base paper on the interleaving paper and applying weight to them and aligning them. can be effectively resolved and reliable collation can be achieved.

In addition, by simply inserting the interleaving paper into the interleaving paper storage space and leaving the rest to the promotion of the common pusher, the intended purpose of collation can be achieved with a very simple and rational means.

In addition, the interleaving paper can be placed in the interleaving paper storage space and left undisturbed to prepare for collation before the base paper reaches the base paper.
There is no need for difficult timing settings as in the conventional example in which interleaving sheets are sent out at the overlapping timing via an oblique conveyor, and the fear of slippage of interleaving sheets and troubles caused by this, which would occur when using an oblique conveyor, can be eliminated.

Further, according to the present invention, automatic collation can be achieved during the movement of the pusher that propels the base paper without performing any special operations such as butting, and a significant improvement in processing speed can be expected.

Furthermore, according to the present invention, the interleaving paper is inserted from the upper side of the conveyance path into the interleaving paper storage space that opens on the conveyance path surface, so the feeding management of the interleaving paper is very easy, and It has many advantages, such as being able to quickly discover and deal with problems.

In the present invention, the above-mentioned interleaving paper feeding device has shown an example in which the interleaving paper is reversed and inserted from above, but it may also be inserted from the diagonal front of the opening slot of the interleaving paper storage space without inverting the interleaving paper. Various paper feeding methods can be applied, such as a method of feeding paper from above a stack of paper, or a method of feeding paper from the side of vertically stacked interleaf sheets.
