CONSTITUTION:In the procedure for forming a certain number of batches (e.g. 20 batches), the first dividing plate 3 is lowered in projection state to a dividing level, and then the preceding parts of the printed articles M which are transported into a piling hopper from the terminals of conveyors 2a and 2b are divided at the twentieth part, and the succeeding parts to the first part are piled on the first dividing plate 3, and the preceding printed articles up to the twentieth part are piled on the first receiving plate 45, and the preceding batch is formed. The plate 3 is gradually lowered at the speed corresponding to the increase of the piling height of the succeeding piled printed-articles M piled on the plate 3. Accordingly, the printed articles M which are transported into the piling hopper from the terminals of the conveyors 2a and 2b are successively piled with a small fall.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is designed to reduce the number of stacked items that have been completely folded in the folding section of a rotary press and are carried out to a predetermined number by linking with an appropriate counting device. Separate and collect the separated items to create small batches (batches), and then collect these small batches to create large batches (batches).
The present invention relates to a series of automatic processing machines, that is, stackers, for creating and discharging stacks, and particularly to stackers capable of high-speed processing.

It was completed. In other words, the configuration of counter stacker 2.”
The second feature is that the sorting mechanism B is placed in the middle of the carrier of the counting and sorting device, as shown in FIG.
As shown in the figure, the table rotation mechanism and the stack creation/unloading mechanism E are integrated (see Figure 1 of Published Practical Application No. 63-93363 and October 31, 1980). ``Shinkai Printing/Printing Edition Revised Edition'' published by the Japan Newspaper Association, p. 354, Figure 8!'I).

[Prior Art] A so-called counter stacker Z, as shown in FIG. 15, is known as a device for sorting and stacking objects carried out from a rotary press into a predetermined number of pieces. This counter stacker 2 consists of a counting and sorting device consisting of a counting mechanism A and a sorting mechanism B, and an accumulating and carrying out device consisting of a small bundle (batch) accumulating mechanism C, a table rotation mechanism (2) and a large bundle creating and carrying out mechanism E. [Problem to be Solved by the Invention J] Regarding the classification of the objects to be accumulated, conventionally, a dividing plate was provided in the middle of a carrier, and the objects to be accumulated (hereinafter referred to as "to be accumulated" It was a composition that separated the "sequence of objects"). Therefore, not only does the length of the carrier become long and it is difficult to shorten it, but also traffic jams occur in the subsequent rows of objects separated by the dividing plates, and the pitch of the rows of objects becomes clogged, resulting in lump-like formations. , which caused a paper jam. In particular, when handling printed matter with a large number of pages per copy, the above-mentioned disadvantages occur frequently, so that it has conventionally been impossible to process printed matter of 40 pages or more, for example. Furthermore, the subsequent rows of items to be accumulated resulting from separation by the dividing board are not subject to overlapping conditions due to traffic jams, such as overtaking where the front and rear printed sheets are reversed, and are accumulated in that condition, so the accumulation is difficult. The packaging of the bodies was uneven, which caused problems with the cargo being disorganized during subsequent processing.

Next, regarding the accumulation of large bundles (stack), conventionally, the rotary table part and the Daito preparation/unloading part have a body structure, so alternate rotations of 180 degrees are required each time a small batch is stacked. Since the small bundles were forced to wait at the fork until the previous small bundles had been turned around, no improvement in processing capacity could be expected. Furthermore, with regard to the production of small fractional bundles, conventional devices have been realized with a decrease in printing speed. A fractional bundle of 140,000 copies and 4 to 7 copies, also 137j' copies of 3 to 5 copies.
It is impossible to create a small fractional bundle, such as three copies, while maintaining high speed.

Means for Solving 1 Problem] The present invention provides the following means for solving the above problem.

In the stat crab equipped with a sorting mechanism, a small bundle (batch) accumulation mechanism, a table rotation mechanism, a large bundle (stack) creation and delivery mechanism, and a control mechanism, the sorting mechanism described in iii. Batch) is arranged directly above the stacking mechanism, and the sorting material belonging to the sorting mechanism can be adjusted to the height of the materials to be stacked that are sequentially carried into the stacking hopper according to a command from the control mechanism. (-1) is provided.

A side plate forming an accumulation hopper in the sorting mechanism,
A bi-precision jogger is attached for aligning paper rows.

A plurality of sorting materials belonging to the sorting mechanism are installed together. Furthermore, a temporary support material is attached to the lowest part of the partition material.

The table rotation mechanism and the Daito (stack) creation/unloading mechanism are arranged vertically and independently, and the former allows a table, a rotation means for the table, and a small bundle provided at the center of the table to fall. It is equipped with an opening and a receiving material that can be opened and closed on the opening, and the latter includes an accumulation hopper, a receiving material that can be opened and closed in the middle of the hopper, and a receiving material that can be opened and closed above and below the collecting hopper. A pusher and a gate for carrying out divided into two stages, and carrying out means provided below the hopper are provided.

[Function] Conventionally, the sorting mechanism provided in the middle of the carrier is disposed in the present invention directly to the small bundle accumulating mechanism in the accumulating hopper, and the sorting mechanism is arranged directly in front of the small bundle accumulating mechanism in the accumulating hopper. Then, the dividing material is displaced to a level slightly lower than the carry-in position, and the dividing material intervenes between the pitches of the objects to be stacked, dividing the row of objects to be stacked, and changing the accumulated thickness of the objects to be carried in. Since the sorting material is removed in accordance with the increase in the number of objects, the subsequent accumulated objects are not blocked at all, and therefore, the subsequent accumulated objects are smoothly separated from the preceding accumulated objects without causing any traffic congestion.

In addition to arranging the sorting mechanism in the accumulation hopper, joggers that can be pipe plated are attached to the four side plates forming the accumulation hopper, thereby eliminating irregularities in the appearance of the accumulated cargo of the objects to be accumulated. Ru.

Next, in the present invention, since the rotary table mechanism and the delivery mechanism are provided vertically and independently, the small bundles on the delivery mechanism can be moved by simply rotating the destination daple once for every two small bundles. The cargoes are all oriented 180 degrees from each other.

Furthermore, in the present invention, a receiving material that can be opened and closed is provided in the middle stage of the hopper of the carry-out mechanism, and the hopper of the carry-out mechanism is partitioned into two stages, upper and lower, and the buttons and gates are also independently divided into the two upper and lower stages in accordance with the above. Because it is attached to the building, the height is, for example, 20
Only the lower mechanism operates when a bundle with a height of less than 0 mm is carried out, and both the upper and lower mechanisms operate simultaneously when a bundle with a height greater than 0 mm is carried out.

Furthermore, it is comprised of a driving means formed by connecting two rods of fluid cylinders 22 and 23 installed in the middle part of the belt 21.

Of the two fluid syringes installed, the shorter fluid shilling 22 produces the effect of descending over a short distance, so it rapidly moves when separating the leading needle and the trailing bone of the printed matter being carried into the collection hopper. In operation, the longer fluid shilling 23 is speed controllable during the lowering and raising of the dividing plate, ie it operates according to the speed of increase in the stacking height of the printed products. However, when the partition plate rises, it quickly returns to its original state.

and 50b, and the other long plate is fixed to the intermediate portion of the belt 49 between the pulleys 50b and 51b. Slider 5
2 is connected to the rod tip of the fluid cylinder 54. Therefore, due to the extension of the rod, the slider 52
is displaced downward in FIG. 4, and along with this, the pair of pulleys 51a and 51b on the slider 52 are also displaced downward by the same distance. Therefore, this displacement is transmitted to the belt 49, and the pulley 50a is moved to the left. As it rotates, one long plate approaches the frame Q on the side plate 56 side, and the pulley 50
b also rotates to the left, and the other long plate approaches the frame Q of the side plate 9 57. In other words, both long plates are separated from each other and the space between them is open, the stack of printed matter P is allowed to fall in the open position, and the stack of printed matter P is stopped from being received in the non-open position. In addition, 53 is a guide bar of the slider 52, and the bar is connected to the bracket 55.
It is constructed between a55a.

Rotating Table Mechanism As shown in FIG. 5, the rotating table mechanism includes a table 60, means for rotating the table 180°, and a mechanism large enough to allow the passage of the accumulated printed matter P provided at the center of the table. an opening 61 and a fourth opening that can be opened and closed over the opening 61;
It consists of a receiving plate 62°62 and a means for opening and closing the fourth receiving plate.

Although the table 60 may have a rectangular outer shape, it is circular in the illustrated embodiment, and the intermediate portion of the belt 100 is wrapped around the outer circumference of the circular table.
0 causes the Q0 pull 60 to alternately rotate 180'' clockwise and counterclockwise.

Its rotation mechanism is as follows. That is, plate 1
06" Eight pulleys 101a, 1o1 pivoted on
b, 101c, 101d01e, 101f, 101g,
101h, and six pulleys 102a, 102b, 102c, 102d, ]02 pivotally supported on the slider 103.

5 is connected to the end of the slider 103. Note that the slider 103 has a pair of guide bars 10.
Slide along 4°104. In this configuration, when the fluid cylinder 105 is stretched, the slider 103 is displaced downward, and the belt 100 is pulled toward the pulley 101d and pulled out from the pulley 101e, so that the table 60 is rotated counterclockwise by 180 degrees.
° Rotate.

1 Similarly, when the rod of the fluid Schilling-105 is shortened, the table 60 rotates 180 degrees clockwise.

The opening/closing means of the fourth receiving plate 62.62 is
are slidably supported by guide bars 63a, 63b, respectively, while the ends of the receiving plates 62, 62 are connected to rods of fluid sills 64a, 64b, respectively. Therefore, due to the expansion of the pair of fluid shillings 84a, 64b, the pair of receiving plates move far away from each other and open the opening 61, so that the accumulation P of printed matter thereon is allowed to fall, while the rod of fluid shilling 105 As a result of the shortening of the pair of receiving plates 62, 62, they approach each other to the position shown in FIG. 5, so that the stack of printed matter P remains placed on the receiving plates. 65a, 65b, 66a, and 66b are side plates.

The means for driving the table 60 to rotate clockwise and counterclockwise by 180 degrees can operate effectively even if the drive source is a motor and the power transmission section is turned on by a rack vinyl 2. Of course.

It was divided into parts and configured to allow each drive to operate independently. Therefore, the large bundle (stack) accumulation/unloading section E according to the present invention can selectively use either individual unloading of only the lower tier or simultaneous unloading of -23 of the upper and lower tiers, depending on the situation.

As shown in FIG. 6, the fifth receiving plate 70.70 has L-shaped members whose upper ends are fixed to shafts 71 and 74, and is installed facing each other, with arms 72.70 projecting from both shafts 7174, respectively. The respective free ends of the arms 72a are connected to each other by a link 73, while a second arm 75 is connected from the shaft 74.
is provided protrudingly, and the free end of the arm is connected to the rod tip of the fluid cylinder 76. Therefore, fluid cylinder 76
The extension of the rod causes the free ends of the fifth receiving plate 70, 70 to open together and move out of the side plates 81 and 82, so that the batch of printed matter placed thereon is removed.
On the other hand, due to the shortening of the rod of the fluid cylinder 76 (solid line position in Figure 6), each free end of the fifth receiving plate 70, 70 approaches each other, and the batch is not placed on the receiving plate. He is stopped and detained.

Description of Sorting Operation (1) The procedure for creating a constant batch (for example, a batch of 20 copies) is as follows.

First, as shown in FIG. 9A, when the first sorting plate 3 is lowered to the sorting level in the protruding position, the preceding portion of printed matter M carried into the accumulation hopper from the terminals of the conveyors 2a and 2b is 20 copies. The subsequent first and subsequent copies are accumulated on the first sorting plate 3, while the preceding 20 copies of printed matter are accumulated on the first receiving plate 45, forming the preceding batch.

The first dividing plate 3 is removed at a speed corresponding to an increase in the stacking height of subsequent printed matter M stacked thereon. Therefore, the printed matter M carried into the accumulation hopper from the terminals of the conveyors 2a and 2b is accumulated one after another with a small head difference (9th
(See Figure B).

6. When the first dividing plate 3 to be discharged falls close to the temporary receiving plate 5, the temporary receiving plate 5 protrudes, and after the protrusion is completed, the first dividing plate 3 retreats. Therefore, the printed matter accumulated on the first dividing plate 3 is transferred onto the temporary receiving plate 5 (see FIG. 9C).

The batch of 20 preceding needles is transferred onto the second receiving plate 46 by the opening operation of the first receiving plate 45, and is further transferred onto the second receiving plate 46.
is moved onto the third receiving plate 47 by the opening operation (see FIG. 1 for the second receiving plate 46 and the third receiving plate 47).

The printed matter transferred onto the temporary receiving plate 5 is transferred onto the first receiving plate 12ii45 by the retreating movement of the temporary receiving plate 5, while the first dividing plate 3, which has completed its retreat first, remains in the standby position in its retreated position. (See Figure 9C).

In the above-described operation, the transfer of printed matter or batches on the first dividing plate 3, temporary receiving plate 5, first receiving plate 45, second receiving plate 46, and third receiving plate 47 is carried out from the receiving side to the preceding one. This is done after waiting for the printed matter or batch to run out.

7 In addition, due to the alternate operation of the first dividing plate 3 and the second dividing plate 4, the
It is also possible to sort by 0 copies.

Explanation of sorting operation (2) The procedure for creating fractional batches (for example, three copies) is as follows.

First, as shown in FIG. 10A, when the first sorting plate 3 is lowered to the sorting level by a predetermined value, the printed matter M carried into the accumulation hopper from the terminals of the conveyors 2a, 2b is sorted, and the subsequent The first and subsequent copies are accumulated on the first dividing plate 3, while the final printed matter of the preceding bone is accumulated on the first receiving plate 45 to form a preceding batch.

Next, as shown in FIG. 10B, the second sorting plate 4 is lowered to the sorting level by the protruding value, and the fourth and subsequent sets of printed matter are placed on the second sorting plate 4.

Therefore, the first division board 3 is removed while accumulating three copies of printed matter on it, and the removal is completed when it is directly above the temporary receiving board 5.

8 After completing the discharge, the first division plate 3 waits for the temporary receiving plate 5 to complete protrusion and then retreats. Therefore, the batch of 3 parts is
It is transferred from above onto the temporary receiving plate 5 (see FIG. 10C).

On the other hand, the subsequent printed products continue to accumulate on the second dividing plate 4, while the temporary receiving plate 5 is retracted and the batch of three parts thereon is transferred onto the first receiving plate 45 (first receiving plate 4). (See diagram 10).

In FIG. 10E, in order to transfer the subsequent printed matter from the second division plate 4 to the temporary receiving plate 5, the latter is protruded and then the former is retreated. During this time, due to the opening operation of the first receiving plate 45,
The batch of three parts is transferred onto the second receiving plate 46, and further transferred onto the third receiving plate 47 by the opening operation of the second receiving plate 46 (
(See FIG. 1 for the second receiving plate 46 and third receiving plate 47).

In FIG. 1O, F, the temporary receiving plate 5 is retracted, and the subsequent printed matter thereon is transferred onto the first receiving plate 45, while the first dividing plate 3 and the second dividing plate 4, which have been completely retracted, are rapidly raised. , returns to the original position.

In the above-described operation, the first partition plate 3, the temporary plate 5, the first plate 45, the second plate 46, and the third plate 47
The transfer of printed matter or batches is carried out after waiting for the previous printed matter or batch to be removed from the receiving and stopping side.

Explanation of overall operation (1) The operation for continuous unloading of a 4-layer stack of 25 batches is as follows.

The sorting mechanism B repeats the sorting of 25 copies by setting the number of printed matter for each sort to 25 by the operation described in the explanation (1) of the sorting operation.

The batch accumulation device C accumulates the printed matter sorted by the sorting mechanism B into each category using a first receiving plate 45 or, as will be described later, a first receiving plate 45 and a second receiving plate 46. The batches are sequentially transferred from the first receiving plate 45 to the third receiving plate 47. The difference in the operation timing of the upstream sorting mechanism B and the downstream table rotation mechanism is adjusted by having the batches stand by on each receiving plate, and by opening the third receiving plate 47, each batch is It is transferred onto the fourth receiving plate 62 of the full rotation mechanism.

In batch production, if the space in the height direction is small and the printed matter cannot be accumulated to a predetermined number using only the first receiving plate 45, the second receiving plate 45 is moved from the first receiving plate 45 onto the second receiving plate 46, and then the second receiving plate 45 is used. A batch is created by accumulating printed matter up to a predetermined number on a board 46.

The table rotation mechanism can load up to two batches on the fourth receiving plate 62''. In normal cases, when the first batch is transferred onto the fourth receiving plate 62, the fourth receiving plate 62
The rotating table supporting the first batch rotates 180" to change the orientation of the first batch, and waits for the next batch to be transferred onto it. Therefore, in this case, the fourth batch After the first batch is transferred to the plate 2 and before the second batch is transferred, the rotary table 60 that supports the fourth receiving plate 62 is rotated 180 degrees to rotate the fourth receiving plate 62. The first batch and the second batch are stacked on the top in reverse directions.Then, every time two batches are stacked, the first and fourth receiving plates 62 are opened, and the two batches are transferred to Daito ( The stack) is transferred onto the delivery belt 96 of the creation mechanism E. At this time, the fifth receiving plate 70 is open.

However, in the following special case, that is, when the large bundle (stack) creation and delivery mechanism E on the downstream side creates and delivers a stack consisting of an odd number of batches, the foremost batch is transferred onto the fourth receiving plate 62. In this case, the preceding batch is directly transferred onto the fifth receiving plate 70 or the carry-out belt 96 of the Daito (stack) creation mechanism E without waiting for the next batch.

The carry-out belt 96 is operated every time four batches are loaded thereon, and the pushers 83, 84 and the gates 77, 78 are operated simultaneously on the upper and lower sides to carry out the four batches as one stack.

In the above-described operation, the transfer of printed matter or loose pieces from the first sorting plate 3 of the sorting mechanism B to the carrying out belt 96 of the large bundle (stack) making and carrying out mechanism E is carried out from the receiving end to the preceding printed matter or batch. This is done after waiting for 2 to run out.

Explanation of overall operation (2) Unloading a fractional batch (3 copies) and then stacking 20 batches in 3 layers The operation for unloading the stack is as follows.

Sorting mechanism B performs the sorting of three copies by the operation described in the explanation (2) of the sorting operation, and then repeats the sorting of 20 copies by the operation described in the explanation (1) of the sorting operation.

The small bundle (batch) accumulating device C is based on the above-mentioned overall operation description (1).
), create a batch of 3 copies and a batch of 20 copies, and sequentially transfer them to the fourth batch of the table rotation mechanism.
Transfer it onto the receiving plate 62.

Since the third batch transferred to the fourth receiving plate 62 is the first batch in the stack consisting of odd numbered batches, the opening operation of the fourth receiving plate 62 causes the Daito (stack) creation/export mechanism E to be unloaded. It is transferred onto the belt 96. At this time, if there is a preceding batch on the delivery belt 96, it is transferred to the -5th receiving plate 730 and waits there. When there is no preceding batch on the carry-out belt 96, the fifth receiving plate 70 is open.

When the three batches of the carry-out belt 96 are transferred, the lower pusher 84 and the lower gate 78 operate in unison.
Carry this out.

Subsequently, the first 20-part batch (the lowest 20-part batch) is transferred to the fourth receiving plate 62. Since this first batch of 20 parts is the leading batch of the stack consisting of odd-numbered batches, the table 60 does not rotate, and the opening operation of the fourth receiving plate 62 causes the batch of first 20 parts to be transferred to the fifth receiving plate. 70
The preceding batch of three parts is transferred to the delivery belt 96.
After waiting for the batch to be carried out by the above operations, the 20-copy batch at the lowest stage is further transferred onto the carry-out belt 96 by the opening operation of the fifth receiving plate 70.

Further, when the second 20-part batch (middle 20-part batch) is transferred onto the fourth receiving plate 62, the table 60 is
After rotating 80 degrees, the third 20-part batch (top 20-part batch) is added to the middle 4-stage 20-part batch.
Then, by opening the fourth receiving plate 62, the middle and upper 20-part batches are transferred onto the lower 20-part batches. At this time, the fifth receiving plate 7
0 is open.

When the 20-part batches in the upper, middle, and lower stages are loaded on the second stage of the delivery belt 96, the upper and lower pushers 83.
84 and the upper and lower gates 77 and 78 operate simultaneously to transport them out as one stack.

In the above-described operation, when the printed matter or batch is transferred from the first sorting plate 3 of the sorting mechanism B to the conveyance belt 96 of the large bundle (stack) creation and conveyance mechanism E, the preceding printed matter or batch disappears from the receiver stop side. Wait for it to be done.

Explanation of overall operation (3) The operation for continuously discharging 20 batches is as follows.

5 Sorting mechanism B repeats the sorting of 20 copies by the operation described in the explanation (1) of the sorting operation.

The small bundle (batch) accumulating device C has the above-mentioned overall operation description (
]) A batch of 20 copies is created by performing the same operation as in case 1), and these batches are sequentially transferred onto the fourth receiving plate 62 of the table rotating mechanism.

In this case, all the batches transferred onto the fourth receiving plate 62 are
Since this is the first batch in a stack consisting of odd numbered batches, the rotation of the rotary table 60 is not used at all, and the fourth receiving plate 6
The batch of 20 copies of "2" is transferred onto the fifth receiving plate 70 by the opening operation of the fourth receiving plate, and the preceding batch is carried out by the operation of the carrying-out belt 96, etc., as will be explained later. After waiting, the fifth receiving plate 70 is opened and transferred onto the carry-out belt 96.

When the 20-part batch is transferred onto the carry-out belt 96, the lower pusher 84 and the lower gate 78 operate simultaneously, and one batch is repeatedly carried out.

In the above-described operation, when the printed matter or batch is transferred from the 16th sorting plate 3 of the 1-sorting mechanism B to the delivery belt 96 of the large bundle (stack) creation/delivery mechanism E, the preceding printed material or batch disappears from the receiver stop side. Wait for it to be done.

Explanation of overall operation (4) Fractional (3 copies) batch, Fractional (18 copies) batch, 25
The operation for successively carrying out the 4-level batch stack is as follows.

Sorting mechanism B performs the sorting into 3 parts by the operation described in the explanation of the sorting operation (2), then similarly sorts the 18 parts, and then further as described in the explanation of the sorting operation (]). By operation, the number of printed matter for each category is 25, 2
Do not repeat the division in Part 5.

The small bundle (batch) accumulating device C has the above-mentioned overall operation description N)
A batch of 3 parts, a batch of 18 parts, and a batch of 25 parts are created by performing the same operation as in the case of 1, and these are sequentially transferred onto the fourth receiving plate 62 of the table rotating mechanism.

7 Since the three batches transferred onto the fourth receiving plate 62 are the first batches in the stack consisting of odd-numbered batches, the fourth receiving plate 62 is subsequently opened, and the large bundle (stack) creation/export mechanism E is unloaded. It is transferred onto the belt 96. At that time, if there is a preceding batch on the carry-out belt 96, the fifth receiving plate 7
It is moved to 0 and waits there. When there is no preceding batch on the carry-out belt 96, the fifth receiving plate 70 is open. When the three batches are transferred to the carry-out belt 96, the lower pusher 84 and the lower gate 78 operate simultaneously to carry out the batches.

The batch of 18 copies transferred to the fourth receiving plate 62 is also carried out in the same manner as the batch of 3 copies described above.

The 25-part batch transferred to the fourth receiving plate 62 is created in the Daito (stack) creation and delivery mechanism E as a 4-tier stack of 25-part batches, and is transported out.
It is carried out by the same operation as described in the description of the overall operation (]).

8 In the above-described operation, the transfer of printed matter or batches from the first sorting plate 3 of the sorting mechanism B to the carrying out belt 96 of the large bundle (stack) making carrying out mechanism E is carried out from the receiving side to the preceding printing unit or batch. It is carried out after waiting for it to disappear.

Above, we have described two examples of segmental operations and four examples of overall operations, but it goes without saying that there are many examples of both segmental and overall operations other than those shown here, and all of these operations is performed in cooperation with the counting device A via the control mechanism F according to a command from the control mechanism F.

The present invention is not limited to the above-described embodiments, but extends to all modifications within the scope of the technical idea described in the claims.

[Advantageous Effects of the Invention 1] As detailed above, in the present invention, the sorting mechanism that was conventionally provided in the middle of the carrier is placed directly above the small bundle accumulating mechanism in the accumulating hopper. Since it can be shortened to, for example, 1/29 of the mold, the entire device can be made compact.

Furthermore, in the present invention, the sorting mechanism is disposed in the accumulation hopper, and the sorting material is removed in accordance with the increase in the thickness of the accumulation of printed matter that is successively carried into the hopper, so that the accumulation of subsequent printed matter is not disturbed. Not only is this not possible, subsequent printed matter is not blocked at all, so there is no risk of paper jams due to blockage due to traffic jams, and smooth sorting and stacking can be achieved.

Furthermore, in the present invention, as a result of eliminating paper jams caused by traffic jams during sorting, it is possible to increase the number of pages per copy of printed matter, even for multi-page printed matter, for example, 48-page printed matter. It is now possible to sort and process items smoothly.

On the other hand, the present invention eliminates paper jams caused by congestion in the sorting process and arranges a vibration jogger in the hopper of the sorting mechanism, so that the stacked loads are now aligned, which eliminates inconveniences in subsequent processing, such as 0 disturbances were also eliminated.

Furthermore, in the present invention, an opening is provided in the rotary table, and the unloading section is separately provided directly below the opening, so that the table can be rotated once for each bundle in the past.
According to the present invention, since it is possible to reduce the number of bundles by half every two bundles at a time, the processing capacity for preparing and transporting the paper has been greatly improved. Furthermore, in relation to the above, in the present invention, since the unloading section is non-rotating,
It has also become possible to simplify the unloading mechanism.

Furthermore, in the present invention, a receiving material that can be opened and closed is provided in the middle stage of the hopper of the carry-out mechanism to partition the carry-out hopper into two upper and lower stages, and accordingly, the button and the gate are also separated and independent into two upper and lower stages. The height of the large bundle, for example, 2
When unloading a bundle of less than 0.00mm, only the lower mechanism is operated, and when unloading a large bundle with a height higher than that, both the upper and lower mechanisms are operated simultaneously. can be dealt with efficiently.

1 Finally, the present invention solves paper jams using a sorting mechanism;
The separation of the unloading mechanism from the rotary table increases the overall throughput, without any reduction in print speed, e.g.
It is now possible to create and export fractional bundles of parts.
