Abstract

PURPOSE:To perform partitioning operation reliably by inserting an partitioning/ receiving member into notes while matching with the timing for transferring the partitioned section of a row of notes windened more than average overlapping pitch to the stacked section. CONSTITUTION:In partitioning device of printed note stacker, a forked partitioning/receiving member 3 for partitioning every predetermined number is waited above the note colliding section of a guiding member crossed in fork then a classifying device comprised of a classifying board 7 and a classifying table 8 will perform damming operation to widen the classifying section of a row of notes more than average overlapping pitch. While matching with the timing for transferring the widened section to the stacked section, the waiting partitioning/receiving member 3 is transferred to the direction opposite from the discharging direction simultaneously with lowering of the notes 11 below the discharging level. Consequently, small bundle under stacking is partitioned and passed to a small bundle receiving member 4 then retreats from the guide member 5 and resets to next partitioning position.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an automatic processing device for printed documents ejected from a printing machine, and in particular to an apparatus for automatically processing printed documents discharged from a printing machine, and in particular, to create a small bundle of small documents by horizontally accumulating the printed documents. The present invention relates to a partition device for

``Prior art'' The printed matter printed by a printing machine is cut and folded into a predetermined size by a folding machine, and then it is further stacked by a stunker, and then paper is applied to the top and bottom of the paper. The tying machine applies the < nt. In order to hang the printed documents on a bat, the printed documents are almost always in a pinch and are thrown into pieces. b:, j: every day tzc
a4p+$'rh % r+ yle--1, In addition, when a certain number of printed documents are stacked 1M, the top surface is usually not horizontal and is folded closer to each other, as shown in Figure 10, for example. The parts are expensive,
When it is further folded into four, the eastern part of the fold becomes the highest. Therefore, in order to make a large bundle with a good packaging shape that is close to a rectangular parallelepiped, it is necessary to stack the small bundles with their orientation changed 180 degrees, and to make the small bundle, it is necessary to stack the small bundles of printed materials that flow in. It is necessary to divide it into a certain quantity suitable for

The conventional method used for this purpose is 1. For example, the printed signatures flow on a conveyor and are dropped one after another onto a partition plate, and when a specified quantity is reached, a stomper on the conveyor is activated to remove the signatures. After temporarily stopping the flow completely, the partition plate is retracted to partition the notebook, and then the partition plate is returned to its original position, and the stopper is also released with a force of 13+1. Occurs or is uneven 1
``Folded toothpicks occur, which is undesirable.

In addition, as an example of a pond, a stopper is not used and there is a stream of paper between two papers that flow continuously in the opposite direction to the flow of the papers.
There is a method of inserting a partition plate, but it is difficult to insert a partition plate between the documents that are sent in 4 to 5 squares at a speed of 10 parts to 20 parts per second.

Figures 6 and 7 are one of the conventional examples, and 5 in 1 drawing.
1 is a printed matter, and the printed matter 51 is a belt conveyor 52.5
3, 54, and 55, the printed matter 51 falls freely onto the printed matter receiver 58A, which serves to partition the printed matter 51, and is accumulated therein. When a predetermined number of printed matter 51' has been accumulated, the stopper 56 is activated, and the knot 51 upstream of the stopper 56 is stopped.
The printed material 51 is no longer transported from the brim to the flow and gradually accumulates on the upstream side, and edges are formed between the printed material 51 and the belt conveyor 54, resulting in scratches on the printed material 51.

On the other hand, the printed matter 51 downstream from the stop/pa 56 is conveyed as it is and is accumulated in the print tray 58A. When the specified quantity of printed matter 51 is stacked 4J, the printed matter receiver 58A is moved back, the small bundle 59 is transferred to the small bundle box 60, the partitioning is completed, and the process proceeds to the next step.

However, in the above case, a certain amount of time is required for the printed matter receiver 58A to retreat and return to its original position, and for this purpose the printed matter 51 on the conveyor 54 is near the front end of the conveyor 54.ivI! If we assume that the length of one copy of the printed matter 51 is 30 cm and the length of the sentence is 10 cm, the total will be 40 cm, and if the pitch is 4 cm as described above, then approximately 10 copies will be Counter stopper 56 must be stopped 311:.

For this reason, during this time, the printed matter 51 is scratched by the belt conveyor, and about 10 copies of the printed matter 51 are pitch-clogged upstream of the counter stopper 56, resulting in a dumpling-like shape 51', resulting in irregularities. . Also, Stoshiba 5
6 is released, the printed matter 51 in a dumpling shape falls freely onto the printed matter receiver 58A, resulting in irregularities, folded edges, and
This is extremely inconvenient as it has the drawback of causing undesirable phenomena such as creases. Then strike like the one above! l
] Also, one category has no equipment and other examples are I! rfl
! Explain.

In Figures 8 and 9, 61 is Conobear.

The printed matter 62 conveyed by the compero 1 advances while being pinched by the presser conveyor 63, hits a stopper 64, stops 1=L, and is stacked while being preloaded by the held of the presser cone hair 63, until it reaches a predetermined position on the partition receiver 65. When the printed matter 62 is piled up, the partition plate 66 moves down from the standby position G to the dividing position H, moves against the flow of the printed matter 62 to position 1, and divides the printed matter 62! 67 is ko/to 761. 63 printed material 6
This is a tk meter that detects 2.

In the above case, the pinch is the same as usual, so it is relatively narrow at 4 to 5 cm like the one in front, and the printed matter 62 is 1 second per second.
It flows at a fast speed of 0 to 20 parts. Therefore, the time lag for inserting the permission key into the predetermined sorting position is an extremely short time of about 57,100 seconds, and the multiple hook-shaped claws can cause the folded notebook to be separated into pieces and caught in the upper F. There was a drawback that the tip of the nail and the tip of the notebook could hit each other, causing trouble.

``Problems to be solved by the invention'' The invention has improved the above-mentioned drawbacks of the conventional technology, and although the section that serves as a stopper allows the device to sink once, the damming time is extremely short and it is cost-effective. In the 11th division, the part is expanded more than the average type or pitch, and the waiting partition receiving member is moved in the direction opposite to the direction of ejecting the signatures at the timing when this expanded part moves to the signature stacking part. The object of the present invention is to provide a partitioning device which partitions the small bundles that are being deposited by lowering them almost simultaneously.

"Configuration of the Present Invention" The present invention will be described in detail below with reference to embodiments of the drawings.

Figure 1, Figure 52 is a vertical sectional side view of the stacker for folded printed matter according to the present invention, where νJ!J?
1.1' is adapted to transport the signature 11 in synchronization with the printing machine. Reference numeral 6 denotes an upper conveyor, and the conveyor 6 is used to collect the documents 11 transferred on the upper surface of the carrier conveyor 1.1'.
to be transferred. The notebook 11 is sandwiched from above and below at the portion overlapping with the upper conveyor 6, and is placed on the upper surface 3 of the fork-shaped partition receiving member 3.
’.

Is 2 a classification? The device 2 consists of a section plate 7 and a section stand 8 for temporarily stopping the flow of the signature 11, and both of them 7.8 are fixed at one point by an air cylinder 9°10.
As shown by the line l11, the forces approaching each other (Q position 7',
8, the signature 11 is caught above the carrier conveyor 1 and temporarily stopped.

12 and 13 are the emitter and receiver of phototubes, both emitter and receiver 1
2.13 starts counting from the signal that is blocked by the leading end of the signature 11, and when a predetermined number of copies is reached, the air shilling 9. 10 is operated, and thereafter, the copies are divided into a predetermined number of copies.

14 is a space in which a predetermined number of copies of the signatures 11 are accumulated;
The notebook 11 is fed in by the partition receiving member 3, and is lowered at a controlled speed so as to keep the level of the top surface of the notebook almost constant.

4 is a small bundle receiving member; 5 is a guide body surrounding the space 14 on the front, back, left and right; the guide body 5 is a small bundle receiving member; the guide body 5 is a small bundle receiving member; the guide body 5 is a small bundle receiving member; It is composed of a guide body 16 at the rear end, a guide body 17 at the tip of the signature, and left and right guide bodies (not shown), and one end of the guide body 17 and at least one of the left and right guide bodies is a positive movement body (not shown). To correctly align the front, rear, left and right directions of the signatures that are swung and accumulated by a device.

Both the finishing paste receiving member 3 and the small bundle receiving member 4 are fork-shaped and can be inserted into the gap between them, and the guide member 16.
17 is also arranged in an appropriate space. While the partition receiving member 3 mentioned above descends to the position 3b, when the upper surface 3' of the partition receiving member 3 becomes lower than the upper surface 4' of the small bundle receiving member 4, the signatures accumulated up to the 111th point are separated into small bundles. It is delivered to the receiving member 4 without any support.

Then, when the partition receiving member 3 descends to the position 3b, it continues to retreat to the position 3c, and then rises to the position 3d δ and waits. Incidentally, when the operation is started and there are no receipts flowing, it is also possible to move forward to 3a and wait. Further, a detailed explanation of the movement from 1:T to 3b to 3d after passing the signature 11 to the small bundle receiving member 4 will be given later.

On the other hand, the small bundle receiving member 4, which has received the signatures 11 from the partition receiving member 3, continues to descend at a controlled speed so as to keep the level of the top surface of the signatures almost constant, and by the time it reaches the position of the flap 4a. , the said division is for air shilling 9. A sorting signal from the counting section is sent to ``to'', and the plate 71 for sorting and the stand 8 for sorting descend and rise, respectively, to suppress the slippage of the signature 11 from above and below and temporarily stop it. Although the pause time here is very short, the signature 11 is divided into sections, and the pitch between the tips of the signatures 11a and 11b is average or larger than a pinch.

When the tip of the signature 11a hits the guide body 17, the signature 1
1a and llb (because there is a large gap A in the nid,
While descending from the standby position 3d, the partition receiving member 3
iii a, and when it is inserted between the signatures 11a and llb at the position 3e, and the partition is performed further to the position 3f, the flow of the signatures 11 is temporarily stopped as described above. The small bundle receiving member 4 switches to rapid lowering and descends to the position 4b, and a little later, as mentioned above, the partition receiving member 3 moves downward and forward from the standby position 3d to the position 3f, and the air cylinder 9 and 10 release the temporary stop of the signature 11 and send the next signature.

The small bundle receiving member 4, which is rapidly switched to the position 4b described above and lowered, descends into the gap 718 to the conveyor for transferring small bundles provided below, and is slightly lowered from the upper surface of the belt of the conveyor [8]. At this time, the small bundle of signatures is transferred to the conveyor 18, and at the same time as this transfer is completed, the conveyor 18 is driven to transfer it to the right, and when the rear end of the small bundle of signatures passes the tip of the small bundle receiving member 4, The small and medium receiving member 4 is rapidly moved one time and returned to the samurai purchase of l↓C, and the small bundle of signatures thus dropped can be used in another process.

Next, the general structure of the vertical movement of the partition receiving member 3 will be explained with reference to FIG.

20 is e! J, the vertical shaft 20 is fixed to the frame 19, and a slide block 21 is loosely fitted to the vertical shaft 20 so as to be movable downward, and one end of the horizontal shaft 22 is fixed to the slide block 21. , and a 7-angle member 23 at the other end.
It is fixed. Piston rod 25 of air cylinder 24 whose lower end is supported by frame 19 and which can be stopped intermediately
Rank 26 to 1. ! The pinion 27 that meshes with the chain wheel 29 that is fixed to one end of the zero rotation shaft 28 that is attached to the rotation shaft 28 that is pivotally supported by the frame 19, and the upper and intermediate points of the vertical shaft 20 Intermediate chain wheel 30 installed in
．． 31 and the end of the roller chain 33 hung on the chain wheel 32 for tension adjustment is connected to a fixed piece 34 fixed to the slide pro 21, and the air cylinder 24 moves in the direction of extending the piston loaf. When activated, the slide block 21 and the horizontal shaft 22 fixed thereto
, the angle members etc. rise in a linear manner, and on the other hand, when the piston rod 25 is retracted, the slide block 21 etc. move downward.

The horizontal shaft 22 has l! so that the slide block 44 can move horizontally. ! Since the partition receiving member 3 is attached to the slide block 44, when the horizontal shaft 22 rises and falls, the partition receiving member 3 also moves up and down together.

In addition, the vertical shaft 20, the slide block 21. The horizontal shafts 22, etc. are symmetrical, and the power of the air cylinder 24 is transmitted from the rack 26. It is transmitted to the other side via the pinion 27 and the rotating shaft 28, and moves in the same manner on the left and right sides.6 Next, the structure of the horizontal movement of the partition receiving member 3 will be explained with reference to FIG.

44 is a slide block, and the slide pro, ri 4
Reference numeral 4 is an M-fitted member on the horizontal shaft 22 for horizontal movement. One end of an air cylinder 35 is connected to the slide pro 21 that moves up and down through a pin 36, and a chain wheel 39° 39' is rotatably provided at both ends of a sliding body 38 fixed to the bisto norot 37, and the pin Chain wheel 40 loosely fitted to 36
The roller chains 743 and 43' are hung on the chain wheel 42 fixed to the rotating shaft 41 provided on the upper surface of the angle member 23 as shown in the figure, and one end of the roller chains 43 and 43' is attached to the connecting piece 45 fixed on the slide block 44. connection,
The other end is connected to and tensioned by adjustment screws 46, 46'.

A chain wheel 42'' is fixed to the other end of the rotating shaft 41 as shown in FIG. 5, and this chain wheel 42' and a rotatable chain wheel 42'' provided on the slide block 21' Both ends of the hung roller chain 747 are connected to connecting pieces 45' fixed to the slide block 44'.

As mentioned above, the partition receiving member 3 is integrally attached to the slide blocks 44 and 44'.+In FIG. is moved towards the chain wheel 39' (sealed roller chain 743
' pulls the slide block 44 to l1 position. Then, when the slide pro 44 moves to the left, the roller chain 743 rotates the chain wheel F42 and the rotating shaft 41 clockwise.
When the chain wheel 42' in FIG. 5 is rotated clockwise by the rotating shaft 41, the roller chain 47 moves the slide block 44' to the left, and the partition receiving member 3 moves to the left. When the air/ring 35 operates in the direction of contracting the piston rod 37, the partition receiving member 3 moves to the right due to the circular action. With this configuration, the stroke of the piston rod 37 can be reduced to half of the horizontal movement distance of the partition receiving member 3, thereby making it possible to reduce the size. The mechanism for vertical movement of the small bundle receiving member 4 is the same as the mechanism for vertical movement of the partition receiving member 3, so a description thereof will be omitted.

Although not shown, a photo sensor is provided on either the left or right side of the guide body 5 at a position 4 to 5 depths below the top surface of the carrier conveyor 1'. Rear, partition receiver 1 casting material 3 or small bundle receiver member 4
descends, and when the level drops, the descent is stopped, and the level of the upper surface of the small east is always kept at a nearly constant position.

"For rl" Next, the operation of the trimming device according to the present invention will be explained.

The signature 11 taken out from the printing machine is conveyed in a constant pinch, and reaches the carrier controller 71.
When the tip of the notebook blocks the phototube 12.13, this signal is transmitted to the counter. The signatures continue to be advanced, and the counter starts counting the preset small bundle of 1 East worth of signatures using this signal as a reference point. Further, when the front end of the signature is shielded from light, the partition receiving member 3, which has been waiting at the position 3a, rapidly descends due to the operation of the signature receiving start position ff13f indicated by a solid line and the air nolling 24, and then stops. The signatures 11 conveyed from the carrier conveyor 1 to the carrier conveyor 1' are sent onto the partition receiving member 3 and are gradually deposited, and the deposited small bundles are detected by a photo sensor (path shown) provided on the guide body 5. After a certain period of time has elapsed, the partition receiving member 3 descends, and when the level drops, it stops and is lowered while keeping the level of the top surface of the notebook almost constant. When the upper surface 3' of the partition receiving member 3 coincides with the t-plane 4' of the small bundle receiving member 4, the partition receiving member 3 is moved from the position 3b to the position 30 by the operation of the flick 35 in response to a signal from a proximity sensor (not shown). Then, the signatures deposited on the partition receiving member 3 are transferred onto the small bundle receiving member 4. Furthermore, the partition receiving member 3 is continuously displaced from the position 3C to the standby position 3d where it is in operation by the operation of the cylinder 24.

The small bundle receiving member 4, which has received the signatures, descends while keeping the top surface of the signatures at a substantially constant level, similar to the bulk receiving member 3. They are aligned by swinging one of the left and right guide bodies. When the small bundle receiving member 4 descends to the position 4a indicated by the -jO line, a signal for ejecting the small bundle 1 east is transmitted from the counter μ to the control box, and at the same time, the air cylinders 9 and 1O are activated. The board 7 for the division and the platform 8 for the division are lowered and raised respectively to stop the signature 11 to the north of the carrier container 1 and temporarily stop it. Then, the small bundle receiving member 4 rapidly descends to the position 4b, and at a timing slightly delayed from the start of this descent, the partition receiving member 3 returns from its standby position 3d to the signature receiving start position 3f shown by the solid line. He was forced to rapidly descend and move to the left.

At the same time, the air cylinders 9 and 10 return the partition plate 7 and the partition table 8, and the once stopped signature 11 moves forward again. Although the above-mentioned temporary stop time is extremely short, the signature 11 is divided into sections, and the pitch of the tip portions of the signatures 11a and 11b is approximately two to three times the pitch of the average type.

By the time the tip of the signature 11 hits the guide body 17, the signature Lla has fallen slightly, and about half of the signature 11b remains on the carrier conveyor 1', so there is no space between the signature 11a and llb. Since a large gap A is created, the partition receiving member 3 descends from the standby position 3d as shown in BO I, moves to the left and rejects as shown by the arrow, and at the position 3e, the partition receiving member 3 is inserted into the signature 11a and ll.
b, and further advances to the starting position of 3f to perform partitioning.

As mentioned above, the damming time of Signature 11 is extremely short, so
There is no pitch jamming and accumulation of signatures 11 in the damming part, so no scratches occur.
Further, the small bundle receiving member 4 that has been lowered to the position 4b passes the small bundle of signatures to the conveyor 18, and then returns to the old position.

``Effects of the Invention'' As described above, the present invention provides transport carriers 1 and 1' for transporting the printed documents 11 that are shifted and overlapped from the printing machine almost in the water direction, and a section provided in the middle of the transport carriers 1 and 1', , a fork-shaped partition receiving member located opposite the end discharge portion of the conveyance carrier and movable in the horizontal direction and the vertical direction, and a small signature bundle receiving member 3 provided below the fork-shaped partition receiving member and movable in the I/F direction.
and a guide body 5 that guides the small bundle of signatures received by the partition receiving member 3 and the small signature bundle receiving member 4 and transferred downward. A fork-shaped partition receiving member for partitioning the eaves is placed on standby above the elimination colliding portion of the guide body that intersects with the fork-like elongation elongation receiving member in a fork-like manner. A damming operation is performed to make the portion wider than the average shape or pitch, and the partition receiving member 3, which is waiting, is moved in a direction opposite to the ejection direction of the signatures at the timing when this expanded portion shifts to the signature stacking area. The small bundles in the middle of being deposited are partitioned by operating almost simultaneously with the transition and the descending below the ejection level of the signature, and after passing the small bundles in the middle of being deposited to the small bundle receiving member waiting below, the guide body By evacuating from the room, rising, and returning to the next partitioning position, the time required for damming the device to be minimized in one section, and the partitioning operation can be performed while suppressing the condition of pitch clogging that occurs in the section of the e-book queue. This is to ensure that this is carried out reliably.

Therefore, in order to separate the documents that are conveyed in a staggered manner at a constant pitch into a certain number of units, this device is equipped with a device for separating the documents, but the damming time is extremely short, and the division of the document procession is very short. The area is expanded to about 2 to 3 times the average pitch, and a J-receiving member is inserted between the notebooks at the same time as the expanded section transitions to the stacked notebook section to create a partition. Conventional partitioning is much easier and more reliable than without the device.

In addition, conventional machines with long cutting times can be easily and reliably machined without causing dumpling-like pitch jams, irregularities in the paperbacks, folded edges, creases, etc. Partitions will be made.
