Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a rotary press for printing newspapers, books and the like, and more particularly to a device for collecting paper pieces, signatures and paper dust accumulated below a folding machine.

[Conventional technology]

"Newspaper Printing, Printing Edition, Revised Edition" edited by The Japan Newspaper Association (No. 104
According to (Page), the places where paper dust is generated in the rotary press are the cutting part, the slitter part and the take-up brake belt part of the folding machine, and the paper dust generation amount is large in the folding machine cutting part.

As a conventional technique for removing such paper dust, there is a "dust collecting suction head in a folding machine of a rotary printing machine" described in Japanese Utility Model Publication No. 54-12403. The conventional technology is that a dust collection suction head that sucks paper dust generated when the printed running paper is cut by the saw blade of the rotary press folding machine is directly attached to the paper dust generation point in the rotary press. There is.

In addition, when starting the printing operation, when the paper is threaded, the paper runs out, and in particular, the paper fragments that fall and accumulate in the hopper located at the bottom of the folding machine, or the folded paper that falls out of the regular flow, are conventionally made of paper dust. When the machine is stopped for the first time after it has fallen into the hopper and left as it is, and the machine is stopped for a considerable amount, or when maintenance, inspection, and maintenance after the work is completed, first manually remove large pieces of paper and signatures. After removal, the medium-sized piece of paper is cleaned with a portable vacuum cleaner along with fine dust.

[Problems to be solved by the device]

The above-mentioned conventional dust collecting suction head does not hinder the traveling of the printed matter and does not sacrifice the operating space of the folding machine, but the mounting position is extremely limited spatially, and the approaching position is approached. Is a narrow area where the folding cylinder and the like rotate at high speed in the vicinity, so it is very dangerous not only during operation but also during maintenance, inspection and maintenance.

Moreover, the main purpose is to collect paper dust, and it is not suitable for suction removal of paper pieces and signatures as described above.

Thus, the conventional work of removing pieces of paper or the like is easy at a place where humans or the tip of an electric vacuum cleaner can enter, but of course not only removing the signature but also the lower part of the folding machine with a narrow structure. It is difficult to remove pieces of paper accumulated in the back of the hopper. Moreover,
It is said that even small pieces of paper cannot be completely removed, and when a considerable amount of paper pieces are left, or when paper dust is collected, the paper pieces are once adsorbed by the suction port of the electric vacuum cleaner and taken out, and then manually removed. There are times when extremely inefficient work is being done.

[Means for Solving the Problems]

A device for collecting paper pieces, signatures and paper dust of a rotary press according to the present invention includes a hopper space in which paper dust, signatures and paper dust of a rotary press fall, and an upper stage position of the hopper space.
A movable member that can reciprocate along the guide in the upstream and downstream directions, is placed on the bottom surface of the hopper space, and the upstream edge is taken out by the movable member or a winding device provided in the movable member. The downstream edge is composed of a bottom surface on the downstream side of the hopper space or a flexible sheet taken out near the bottom surface. In some cases, a dust collection bucket is installed adjacent to the downstream side of the downstream edge attachment location of the flexible sheet.

[Action]

First, usually, the moving member is placed at the upstream end, the flexible sheet is spread on the bottom surface of the hopper space, and small-sized paper powder or large-sized paper pieces dropped from the folding machine of the rotary press are used. Furthermore, the folded sheets that have not been properly carried out from the delivery unit of the folding machine and have fallen are accumulated on the flexible sheet.

When collecting and removing the accumulated paper pieces, signatures and paper dust, the moving member moves from the upstream side to the downstream side, and the flexible sheet folds the accumulated paper pieces, signatures and paper dust, and folds them back together. Be done.

As the movement of the moving member progresses, the flexible sheet becomes a bag shape, and eventually, the paper pieces, the signatures, and the paper powder are collected and wrapped in the downstream side. Paper pieces, signatures, and paper dust collected on the flexible sheet at the downstream end are easily collected and removed by an appropriate means.

When the work of collecting and removing the paper pieces, the signatures, and the paper dust is completed, the lower moving member moves from the downstream end to the upstream side. Thus, the flexible sheet returns to the original state in which it is spread on the bottom surface of the hopper space.

When the upstream edge of the flexible sheet is attached to the flexible sheet winding device of the moving member, the accumulated paper pieces,
When the moving member moves from the upstream side to the downstream side when collecting and removing the signature and the paper dust, the flexible sheet winding device moves to the downstream side together with the moving member while winding the flexible sheet.

Therefore, the paper pieces, signatures, and paper dust accumulated on the flexible sheet are gradually gathered toward the downstream side.

Then, when the moving member moves to the downstream end, the flexible sheet is wound around the flexible sheet winding device without slack and becomes substantially upright. If it reaches the downstream end of the bottom surface of the space and a dust collecting bucket is installed, it is removed in the dust collecting bucket.

And the downstream edge is attached to the bucket rim position on the bottom surface of the hopper space 1.

In the third embodiment, as shown in FIGS. 9 and 10, a net bottom bucket 20 having a net-like bottom is used in place of the bucket 19 in the second embodiment, and a bucket installation recess is provided at the bottom of the suction pipe. The second embodiment has the same configuration as that of the second embodiment except that it is formed as a dust collecting hopper 22 to which 21 is connected and the suction pipe 21 is connected to a vacuum dust collector (not shown).

The operation and action of the paper pieces, signatures, and paper dust collecting and collecting device of each of the above embodiments will be described.

In the first embodiment, first, normally, the sliding blocks 9 and 10 are
Is placed at the upstream end (right end in the drawing), the flexible sheet 12 is spread on the bottom surface of the hopper space 1, and a large piece of paper A dropped from the folding machine of the rotary press into the hopper space 1.・ Folder B and small paper dust C are flexible sheets 12
Deposit on top (see FIG. 2). Then, the paper piece A, the signature B, and the paper powder C that have fallen around the hopper space 1 are not stopped by the eaves-like inclined plate 13 and at least the flexible sheet.
12 falls on.

When collecting and removing the accumulated paper pieces A, signature B, and paper dust C, the lower traveling side of the endless rope 4 is manually operated to travel from the upstream side to the downstream side (or the upper traveling side to the downstream side to the upstream side). Run the endless rope 4. Then, the sliding blocks 9 and 10 slide by being guided by the guide lines 7 and 8, and the frame bar 11 moves to the downstream side together, so that the flexible sheet 12 includes the accumulated paper pieces A, signatures B and paper dust. It is folded back while gathering and collecting C (see FIG. 3).

As the endless rope 4 travels, that is, as the sliding block 9 moves, the flexible sheet 12 becomes a bag-like shape, and eventually the paper piece A,
The signature B and the paper dust C are gathered together and collected in the downstream side, and the sliding blocks 9 and 10 come into contact with the brackets 6 and 6 on the downstream side (fourth part).
See figure).

The paper pieces A, the signatures B, and the paper powder C gathered together on the downstream end on the flexible sheet 12 are easily collected and removed by an appropriate means.

After the work of collecting and removing the paper piece A, the signature B, and the paper dust C is completed, the downward traveling side of the endless rope 4 moves from the downstream side to the upstream side until the sliding blocks 9 and 10 come into contact with the upstream brackets 5 and 5. Alternatively, the endless rope 4 is run so that the upper running side runs from the upstream side to the downstream side. Thus, the flexible sheet 12
Returns to its original state (see FIG. 2) when it is spread on the bottom surface of the hopper space 1.

In the second embodiment, first, the sliding blocks 9 and 10 are usually placed at the upstream end (right end in the drawing) as in the first embodiment.

Are deposited on the flexible sheet 12 (see FIG. 6).

When collecting and removing the accumulated paper pieces A, signatures B and paper dust C, the lower traveling side of the endless rope 4 is manually operated to travel from the upstream side to the downstream side (or the upper traveling side is traveled from the downstream side to the upstream side). Run the endless rope 4. Then, the sliding blocks 9 and 10 slide by being guided by the guide lines 7 and 8, and the rotating shaft 14
Since they both move to the downstream side, the timing pulley 16 whose lower peripheral surface meshes with the timing belt 18 rotates counterclockwise in FIG. As a result, the take-up roller 15
Rotate in the counterclockwise direction together with the rotating shaft 14, and the flexible sheet 12
It moves to the downstream side while being rolled up.

Therefore, the paper pieces A, the signatures B, and the paper powder C deposited on the flexible sheet 12 are gradually gathered toward the downstream side (see FIG. 7).

Then, the sliding blocks 9 and 10 are attached to the brackets 6 and 6 on the downstream side.
When it moves until it comes into contact with, the take-up roller 15 is positioned ahead of the fixed edge on the downstream side of the flexible sheet 12, and the flexible sheet 12 is wound around the take-up roller 15 without slack. Therefore, the paper piece A, the signature B, and the paper dust C collected on the flexible sheet 12 at the downstream end are collected in the bucket 19
Are excluded (see FIG. 8).

After the collection and removal of the paper piece A, the signature B and the paper dust C are completed, until the sliding blocks 9 and 10 come into contact with the upstream brackets 5 and 5,
The endless rope 4 is run so that the lower running side of the endless rope 4 runs from the downstream side to the upstream side (or the upper running side from the upstream side to the downstream side). Then, the operation opposite to the above is performed, and as a result, the winding roller 15 rotates counterclockwise together with the rotating shaft 14 and moves to the downstream side while rewinding the flexible sheet 12. Thus, the flexible sheet 12 is returned to the original state (see FIG. 6) when it is spread on the bottom surface of the hopper space 1.

Paper pieces A, signatures B and paper dust C accumulated in the bucket 19 are
The bucket 19 is taken out from the bucket setting recess and then discarded.

In the third embodiment, the paper pieces A, the signatures B and the paper dust C deposited on the flexible sheet 12 are removed in the net bottom bucket 20 in the same manner as in the second embodiment. Then, the large-sized paper piece A and the signature B are received by the mesh bottom of the mesh bottom bucket 20 and stay there, and the small size paper powder C passes through the mesh of the mesh bottom and is further collected in the dust collecting hopper 22. Falls to the bottom,
It is sucked and removed through the suction pipe 21 by a vacuum dust collector (not shown) (see FIG. 11). The paper pieces A and signatures B retained in the net bottom bucket 20 are discarded in the same manner as in the second embodiment.

The movement of the sliding blocks 9 and 10, that is, the traveling of the endless rope 4 in each of the above-described embodiments is performed manually, but an appropriate drive device is used, and further, the brackets 5 on the upstream side and the downstream side, Instead of using 6 as a mere stopper, the upstream side bracket 5 may be used as the stop position sensor mounting portion of the drive device, and the downstream side bracket 5 may be used as the inversion position sensor mounting member of the drive device, and may be automated. . The sensor may be a well-known one, and its installation location can be appropriately selected other than the brackets 5 and 6 depending on the moving range of the sliding blocks 9 and 10.

As the drive device, for example, one of the pulleys 2
(3), or a motor or the like that directly or indirectly rotationally drives the rotary shaft 14.

The moving mechanism of the sliding blocks 9 and 10 is, in each embodiment,
Although it is an endless rope / pulley mechanism, it may be a fluid pressure cylinder mechanism.
