Description

  The present invention relates to a rotary printing press.

In the folding part of the rotary printing press, the printed web is folded in two vertically by a triangular plate, cut to a predetermined length, and made into a folded book. The folded book is formed in a predetermined configuration by parallel folding (with the width direction as a fold) or right-angle folding (with the conveyance (top / bottom) direction as a fold). This signature is decelerated by the impeller and the conveyance direction is adjusted, and is carried out of the machine.
When the web transport speed is slow, such as when printing is started or stopped, the web tension becomes unstable, causing the paper to meander (paper flow) in the width direction or vary the transport speed. . As a result, the folding position of the origami has shifted from the folding position of the triangular plate, and the width of the vertically folded paper is not uniform, deformed, or wrinkled.

The folded folding book may be clogged in a downstream portion such as an impeller. When a paper jam occurs in this way, the printing operation of the rotary printing press is once stopped, and after the paper jam is removed, the printing operation is resumed, so that the printing work efficiency is lowered.
In particular, as shown in Patent Document 1, two or more impellers are equipped, and origami that is continuously conveyed is distributed alternately for each predetermined number of copies, and each impeller is used for division processing. Since the paper is nipped by the belt and conveyed, the folding timing is likely to be shifted and the paper jam tends to occur.

That is, since a non-folded signature has a non-uniform force acting on the signature in the width direction, it tends to be inclined. In addition, when one end portion of the signature is greatly protruding from the path, the conveyance posture or the conveyance speed may change due to contact with a peripheral member or an increase in air resistance on the side.
As described above, when the conveyance speed or conveyance posture of the signature is changed, the timing of entering the impeller is shifted, so that the signature may be clogged at the impeller.
In order to maintain the printing work efficiency, at the start or stop of the printing work, an operator monitors the conveyance state of the origami and removes an origami that may be clogged from the conveyance path.

JP 7-125900 A

By the way, in what is shown by patent document 1, since it is necessary to arrange | position an operator in order to monitor the presence or absence of a signature which may be clogged at the time of the start or stop of a printing operation, it will cost that much Become.
In addition, there is a risk of injury because the signatures that may be jammed by the worker are manually removed from the transport path.
For example, if the worker is not arranged, a paper jam may occur at the impeller, so that the work efficiency is reduced due to the recovery work in the case where it occurs.

  In view of the above problems, an object of the present invention is to provide a rotary printing press capable of suppressing the occurrence of a paper jam by allowing a folded sheet being conveyed to be discharged out of a path.

In order to solve the above problems, the present invention employs the following means.
That is, the rotary printing press according to the present invention is arranged in the folding unit, and the sorting device that sorts the continuously fed folding books in two directions alternately every predetermined number of copies, and is sorted by the sorting device. A first transport path that transports one of the signatures to the first impeller, and a second transport path that transports the other signatures distributed by the sorting device to the second impeller. A rotary printing press that includes a sorting direction fixing device that fixes the distribution of the signature in the sorting device to the first transport path unit side, and is provided in the middle of the first transport path unit, And a branching portion that selectively directs the conveyance direction of the folding book to the outside of the path.

According to the present invention, the signatures processed from the printed web and continuously conveyed are distributed to the first conveyance path unit or the second conveyance path unit by the sorting device every predetermined number of copies. It is conveyed to the impeller or the second impeller.
For example, when the printing speed is slow and the web tension is unstable, such as at the start or stop of the printing operation, the sorting direction fixing device transfers the signatures in the sorting device to the first transport path section. While being fixed to the side, the branch part in the first transport path part is positioned so that the transport direction of the folding book goes out of the path.

As a result, all the signatures are sent to the first conveyance path section and discharged through the branch section to the outside of the path, so that the signatures that may be clogged are discharged to the outside of the path. Become. Since the signature that may be clogged is discharged out of the path, it is possible to prevent the signature from being clogged in the first impeller or the second impeller.
In this case, if the printing speed is increased to a certain extent and the web tension is stabilized, there will be no broken folding book, so that the sorting direction fixing by the sorting direction fixing device is stopped and the branching portion is directed to the first impeller. To. Thereby, the continuously conveyed origami is distributed to the first conveyance path part or the second conveyance path part for each predetermined number of copies by the sorting device, and conveyed to the first impeller or the second impeller. Processed normally.

Note that if the cutting register adjustment is not completed at this point, a booklet whose cutting position does not match the pattern (not a product) is sent to the first impeller or the second impeller. The book is discharged at the downstream side of the first impeller or the second impeller because there is no possibility of clogging the first impeller or the second impeller. In this case, the return of the sorting direction fixing device and the branching portion may be stopped, and the signature whose cutting position does not coincide with the pattern may be continuously discharged at the same position.
Thus, since it becomes unnecessary to arrange an operator in order to prevent the first impeller or the second impeller from being clogged, the operating cost can be reduced accordingly. Further, since the moving origami is not removed by hand, it is possible to prevent a worker from being injured.

  Moreover, in the said invention, said 1st conveyance path part is comprised by the 1st conveyance belt which clamps both surfaces of the said folding book, and said 2nd conveyance path part is the 2nd conveyance belt which clamps both surfaces of the said folding book. The sorting device is a pair of facing the first transport path section or the second transport path section on the downstream side of the separation position of the first transport path section and the second transport path section. A guide member having a guide surface is provided, and the signature is sorted by moving at least an upstream portion of the guide member to the first transport path portion side or the second transport path portion side. .

According to the present invention, when at least the upstream part of the guide member is moved to the first transport path part side, the folded book is guided to the second transport belt side by the guide surface facing the second transport path part of the guide member. , Sandwiched by the second conveyor belt and conveyed to the second impeller. On the other hand, when at least the upstream part of the guide member is moved to the second transport path part side, the folded book is guided to the first transport belt side by the guide surface facing the first transport path part of the guide member, and the first transport It is pinched by the belt and conveyed to the first impeller.
Therefore, it is possible to sort the signatures by moving at least the upstream portion of the guide member to the first conveyance path portion side or the second conveyance route portion side for each predetermined number of signatures.

  Further, in the rotary printing press according to the present invention, the sorting device sorts the signature by the operation of a cam that rotates in synchronization with a printing speed, and the sorting direction fixing device operates the cam. The distribution direction of the guide member can be set independently.

In this way, the sorting device sorts the signatures by the operation of the cam that rotates in synchronization with the printing speed. Therefore, when the printing speed is slowed, the sorting timing is also slowed, and conversely, when the printing speed is fastened. The distribution timing is also faster. Therefore, since the distribution timing automatically follows even when the printing speed changes, it is possible to distribute the origami for each predetermined number of copies without adjustment.
Further, since the distribution direction fixing device can set the distribution direction of the guide member independently of the operation of the cam, the operation of the cam is not transmitted to the guide member, for example, the operation of the cam is transmitted. The cam follower can be fixed in the sorting direction in which the signature is discharged by setting the sorting direction of the guide member to the first transport path portion side so that the cam follower does not contact the cam.
In this case, since the cam switching position is the boundary between the predetermined number of copies, if the distribution direction fixing by the distribution direction fixing device is released at this position and the distribution by the cam is performed, the folding is performed. It is possible to reliably distribute the book every predetermined number of copies.

  Further, in the rotary printing press according to the present invention, the branching portion is capable of swinging around the upstream end portion in the intersecting direction intersecting the plane of the folding book at least the downstream end portion of the first transport path portion. It is characterized by comprising.

In this way, the branch portion is configured such that at least the downstream end portion of the first transport path portion can swing around the upstream end portion in the intersecting direction intersecting the plane of the folded book, That is, when at least the downstream end portion of the first transport path portion is swung around the upstream end portion, the downstream end of the first transport path portion, that is, the position where the exit of the folding book faces the first impeller , It is possible to switch to a position not facing the first impeller.
When the sorting direction fixing device fixes the sorting direction of the signature on the first transport path part side, the branching part is swung, and the downstream end position thereof is switched to a position not facing the first impeller. Thereby, the signature which passes a 1st conveyance path | route part can be discharged | emitted out of the path | route different from a 1st impeller.
In addition, it is suitable for a branch part to be provided in the downstream end part of a 1st conveyance path | route part. In this way, since a long distance from the sorting device to the branching section can be secured, it is possible to earn time for moving the branching section, and to cope with an increase in the conveyance speed of the signature.

  The rotary printing press according to the present invention includes a timing detection device that detects a timing at which an end portion of the predetermined number of the origami reaches the guide member.

  When the fixing of the sorting direction by the sorting direction fixing device is released at the timing at which the end of the predetermined number of folding books detected by the timing detection device reaches the guide member, the sorting device is moved at the end of the predetermined number of folding books. Since the minutes are restored, the origami can be reliably distributed for each predetermined number of copies.

Moreover, in the said invention, it is desirable for the said timing detection apparatus to detect the switching position of the said cam.
Since the cam switching position is the boundary of the signature for each predetermined number of copies, detection of this position can reliably detect the boundary for each predetermined number of copies of the signature.

  According to the present invention, the distribution direction fixing device for fixing the distribution of the signature in the distribution device to the first conveyance path portion side and the middle of the first conveyance route portion are provided, and the conveyance direction of the signature is selected. For example, when the printing speed is slow and the web tension is unstable, such as when printing is started or stopped, the distribution direction is fixed. The device locks the distribution of the signature in the distribution device on the first conveyance path section side and positions the branch portion in the first conveyance path section so that the conveyance direction of the signature is directed out of the path. It is possible to suppress the feared signatures from being discharged out of the path and clogging the signatures in the first impeller or the second impeller.

A plurality of, for example, three distribution guides 165 are provided at intervals along the swing shaft 167, and their downstream end portions are fixedly attached to the swing shaft 167.
The sorting guide 165 swings as the swinging shaft 167 reciprocates and rotates so that the lower guide surface 173 or the upper guide surface 175 is selectively positioned on the conveyance path K of the signature 67.

The sorting cam follower 169 is fixedly attached to one end of the swing shaft 167. The distribution cam follower 169 is always urged to move toward the distribution cam 171.
The sorting cam 171 is a plate member that is disposed so that the surface portion is substantially orthogonal to the transport path K. The distribution cam 171 is attached to a frame (not shown) so as to be rotatable in its plane.
The distribution cam 171 is provided with a large-diameter portion 177 having a substantially semicircular shape with a large radius and a small-diameter portion 179 having a substantially semicircular shape with a small radius.

Since the distribution cam follower 169 is pressed against the distribution cam 171, the distribution cam 169 moves from the large diameter portion 177 to the small diameter portion 179 or from the small diameter portion 179 to the large diameter portion 177 as the distribution cam 171 rotates. In this case, the position is changed. The swinging shaft 167 is rotated by the change in the position of the sorting cam follower, and the sorting guide 165 is swung.
When the distribution cam follower 169 is engaged with the small diameter portion 179, the upper guide surface 175 is positioned in the transport path K (see FIG. 6), and when the distribution cam follower 169 is engaged with the large diameter portion 177, the lower guide surface 173 is It is located on the transport path K (see FIG. 7).

The distribution device 49 is provided with a distribution direction fixing device 181 that fixes the distribution direction. The sorting direction fixing device 181 includes an operation plate 183 and a fixed air cylinder 185.
The operation plate 183 is a substantially rectangular plate member, and is attached so that one end thereof is fixed to the swing shaft 167. A substantially semicircular groove 187 is provided in the upper part of the other end of the working plate 183.

The fixed air cylinder 185 is fixedly attached to a frame (not shown). A pair of attachments 189 are attached to the end of the rod of the fixed air cylinder 185 so as to sandwich the operation plate 183. The attachment 189 is provided with a long hole 191 that extends in the direction of expansion and contraction of the rod. The pin 193 is disposed so as to penetrate the long hole 191 of both attachments 189. The pins 193 are attached so as to be movable outside the respective attachments 189 and are movable along the long holes 191.
As the position of the distribution cam follower 169 is changed by the distribution cam 171, the operating plate 183 swings up and down, and the groove 187 moves the pin 193.

The shape of the long hole 191 is set so as to allow the movement of the pin 193 when the rod of the fixed air cylinder 185 is extended.
On the other hand, when the rod of the fixed air cylinder 185 is contracted, the movement of the pin 193 is restricted as shown in FIG. 8 and the operation plate 183 is forcibly swung (clockwise in FIG. 8). This swinging causes the swinging shaft 167 to rotate clockwise in FIG. 8, and the sorting cam follower 169 is positioned at a position where it does not engage with the sorting cam 171. At this time, as shown in FIG. 8, the lower guide surface 173 is positioned on the transport path K, and the transport path K of the folding book 67 is fixed to the lower transport path portion 69 side.

The sorting cam 171 is configured to rotate in synchronization with the plate cylinder 19 so that the rotation of the plate cylinder 19 also makes one rotation. The timing at which the distribution cam follower 169 moves from the large diameter portion 177 to the small diameter portion 179 of the distribution cam 171 or from the small diameter portion 179 to the large diameter portion 177 is made to coincide with the leading position or the intermediate position of the printed pattern. Yes.
For example, if the cut-off 67 is 187 mm, the conveyance path K is switched every 6 copies if the cut-off is 187 mm and every 374 mm.

The distribution cam 171 includes a timing detection device 195 that detects this timing.
The timing detection device 195 includes a pair of detection pieces 197 attached to the rotation shaft of the sorting cam 171 and a proximity switch 199 that detects passage of the detection piece 197.
The distribution direction fixing device 181 includes an operation unit 201 that expands and contracts the fixed air cylinder 185, and a fixing control unit 203 that controls the operation of the operation unit 201 (see FIG. 8).
The fixed control unit 203 is configured to receive the operation speed of the rotary printing press 1 from a main control unit (not shown), and operates the operation unit 201 until the operation speed reaches a predetermined speed, for example, 15 rpm, so that the fixed air cylinder 185 is operated. Is set so that the conveyance path K of the folding book 67 is fixed to the lower conveyance path 69 side.

The operation of the rotary printing press 1 according to the present embodiment described above will be described.
When the printing operation is started, the web 15 is unwound from the paper feeding device 3. The tension of the web 15 is adjusted by the infeed device 5 and supplied to the printing unit 7.
In the printing unit 7, the image formed on the printing plate attached to the peripheral surface of the plate cylinder 19 by supplying dampening water and ink is transferred to the blanket cylinder 21. This is transferred and printed on both sides of the web 15 passing between the blanket cylinders 21 and 21.
With the rotation of the plate cylinder 19 and the blanket cylinder 21, 12 pages are printed on the web 15 in the transport direction H and 8 pages in the width direction, so 192 pages are printed on both the front and back sides. At this time, on the web 15, pages 1 to 96 are printed in that order in the first half, and in the second half, the top and bottom are printed in the order of 192 to 97 pages.

The web 15 printed by the printing unit 7 is heated by the drying device 9 to dry the ink.
Next, the web 15 passes so as to contact the peripheral surface of each cooling drum 23 of the cooling device 11, is cooled by each cooling drum 23, and is supplied to the folding portion 13.
The web 15 guided to the folding portion 13 is divided into two parts by a slitter 25 having a substantially central portion in the width direction cut vertically. The web 15 divided into two is tensioned by the first drag roller 27 and introduced into the middle triangular plates 29a and 29b.

The webs 15 introduced into the middle triangular plates 29a and 29b are each folded in two vertically and guided by the first lead-in rollers 31a and 31b. The web 15 is fold-pressed by the first nipping rollers 33a and 33b, is given tension, and is sent to the downstream side.
The two folded webs 15 fed from the first nipping rollers 33a and 33b merge and overlap each other. The overlapped web 15 is processed with a perforation that becomes a crease at a substantially central portion in the width direction by the vertical perforation blade 35.

The overlapped web 15 is given a tension by the second drag roller 37, is introduced into the small triangular plate 39, is folded at a substantially central portion where the perforation is processed, and is folded in two vertically. Thereby, the web 15 is folded to one-eighth of the original width, that is, one page width.
The web 15 is guided by the second lead-in roller 41, the crease is pressed by the second nipping roller 43, tension is applied, and the web 15 is fed downstream.
The web 15 folded in the width direction is cut, for example, in units of 187 mm by the cutting blade 63 of the cutting device 45, and a folded book 67 is formed. That is, page 1 to page 192 are divided into 12 copies of origami 67.

The origami 67 is nipped and conveyed by the lower outer conveyor belt 73 and the upper outer conveyor belt 77 and reaches the sorting device 49.
The fixed control unit 203 contracts the rod of the fixed air cylinder 185 by the operating unit 201 when the initial printing speed is low. When the rod of the fixed air cylinder 185 is contracted, the movement of the pin 193 is restricted, and the pin 193 further swings the operating plate 183 clockwise in FIG.
The swinging shaft 167 rotates clockwise in FIG. 8 due to the swinging of the operation plate 183, so that the sorting guide 165 swings to the right and the lower guide surface 173 is positioned in the transport path K.
At this time, since the distribution cam follower 169 is positioned at a position where it does not engage with the distribution cam 171, the conveyance path K of the folding book 67 is fixed to the lower conveyance path 69 side.
The conveyance path K of the folding book 67 is fixed to the lower conveyance path unit 69 side.

At this time, the rod of the air cylinder 159 is contracted to move the connecting frame 157 upward. By the movement of the connecting frame 157, the swing frame 153 swings upward about the guide roller 90, and the moving frame 155 moves upward.
By the movement of each frame, the lower transport path 69 is bent at the downstream end of the transport path at the guide roller 90, and is positioned at the out-path discharge position shown in FIG.
As a result, one end of the discharge guide plate 161 is positioned at the extended position of the lower transport path portion 69.

Therefore, the signature 67 is guided by the lower guide surface 173 of the distribution guide 165 and introduced between the lower outer conveyor belt 73 and the lower inner conveyor belt 75. The signature 67 that is nipped and conveyed by the lower outer conveyor belt 73 and the lower inner conveyor belt 75 is discharged from the downstream end onto the discharge guide plate 161, guided there, and discharged into the discharge box 163.
When the printing speed is low, all the signatures 67 are sent to the lower conveyance path 69 and discharged through the branching section 151 to the discharge box 163 outside the path, which may cause clogging. The signature 67 is discharged out of the path.
As described above, since the signature 67 that may be clogged is discharged out of the path, it is possible to prevent the signature 67 from clogging the lower impeller 51 or the upper impeller 53.

When the printing speed is increased, the web tension is stabilized, and the folded or broken signature 67 disappears.
For example, when the printing speed reaches 15 rpm, the fixed control unit 203 operates when the timing detection device 195 detects the timing at which the distribution cam follower 169 moves from the large diameter portion 177 to the small diameter portion 179 of the distribution cam 171. The rod of the fixed air cylinder 185 is extended by the part 201. When the rod of the fixed air cylinder 185 is extended, the pin 193 can move freely. Since the distribution cam follower 169 is constantly urged toward the distribution cam 171, the distribution cam follower 169 is engaged with the small diameter portion 179 of the distribution cam 171.

When the sorting cam follower 169 is engaged with the small diameter portion 179, the upper guide surface 175 is positioned in the transport path K as shown in FIG. For this reason, the signature 67 is guided by the upper guide surface 175 of the distribution guide 165 and is introduced between the upper / lower conveying belt 77 and the upper / inner conveying belt 79.
At this time, since the distribution cam 171 rotates in synchronization with the plate cylinder, for example, one page is printed at the timing when the distribution cam follower 169 moves from the large diameter portion 177 to the small diameter portion 179 of the distribution cam 171. The folded book 67 reaches the sorting device 49 and is sorted first.
In this way, six copies 67 of pages 1 to 96 are sequentially conveyed to the upper impeller 53 by the upper conveyance path 71.

As described above, when the distribution direction fixing device 181 releases the fixing in the distribution direction at a predetermined number of copies detected by the timing detection device 195, for example, at the timing when the end portion of the six copy books 67 reaches the distribution guide 165, Since the sorting of the sorting device is restored at the end portion of the predetermined number of folding sheets 67, the folding sheets 67 can be reliably sorted every six copies.
That is, the switching position of the large-diameter portion 177 and the small-diameter portion 179 of the sorting cam 171 that rotates in synchronization with the plate cylinder 19 is the boundary of the folding book 67 every six copies. , It is possible to reliably detect the boundary of every six copies of the signature 67.

When the six-fold folding book 57 passes, the distribution cam follower 169 is moved to the large-diameter portion 177 from the small-diameter portion 179 of the distribution cam 171 by the rotation of the distribution cam 171. At this timing, for example, the folding book 67 on which 192 pages are printed reaches the sorting device 49.
When the distribution cam follower 169 moves to the large diameter portion 177, the swing shaft 167 swings, and the lower guide surface 73 of the distribution guide 165 is positioned in the transport path K. The signature 67 is guided by the lower guide surface 173 of the distribution guide 165 and is introduced between the lower outer conveyor belt 73 and the lower inner conveyor belt 75.
In this way, six copies 67 from page 192 to page 97 are sequentially conveyed to the lower impeller 51 through the lower conveyance path unit 69.

The rod of the air cylinder 159 is extended and the connecting frame 157 is moved downward until the leading end of the folding book 67 conveyed by the lower conveyance path 69 reaches the guide roll 90. By the movement of the connecting frame 157, the swing frame 153 swings downward about the guide roller 90, and the moving frame 155 moves downward.
By the movement of each frame, the lower conveyance path portion 69 is positioned at a position where the conveyance path at the downstream end can be discharged to the lower impeller 51 shown in FIG.

  Thus, since the branching part 151 is provided in the downstream end part of the lower conveyance path | route part 69, the distance from the sorting apparatus 49 to the branching part 151 can be ensured long. Therefore, it is possible to earn time for moving the branching portion 151, and to cope with an increase in the conveyance speed of the signature 67.

Thereafter, the distribution direction of the distribution device 49 is alternately distributed to the upper conveyance path portion 71 and the lower conveyance path portion 69 by the rotation of the distribution cam 171 that rotates in synchronization with the plate cylinder 19.
As described above, the sorting device 49 sorts the signature 67 by the operation of the sorting cam 165 that rotates in synchronization with the printing speed. Therefore, when the printing speed is slowed, the sorting timing is also slowed. As the printing speed increases, the sorting timing also increases. Therefore, since the distribution timing automatically follows even when the printing speed changes, it is possible to distribute the origami 67 for each predetermined number of copies without adjustment.

Folds 67 transported by the lower transport path 69 are sequentially discharged from the lower impeller 51 and stacked on the lower table 133 to form a folded bundle 149. The folded book bundle 149 is, for example, in order from page 192 to page 97 in order from the bottom.
The folded bundle 149 is discharged in the discharge direction HH by the pusher 141 of the lower first carry-out conveyor 135, the pusher 143 of the lower second carry-out conveyor 137, and the pusher 145 of the lower third carry-out conveyor 139.

On the other hand, the signatures 67 conveyed by the upper conveyance path 71 are sequentially discharged from the upper impeller 53 and stacked on the upper table 125 to form a signature bundle 132. The folded bundle 132 is, for example, in order from the first page to the 96th page from the bottom.
The folded bundle 132 is conveyed by the pusher 129 of the upper carry-out conveyor 127, reversed by the reversing impeller 123, and stacked on the folded bundle 149 conveyed by the pusher 145 of the lower third discharge conveyor 139.
The stacked origami bundles 132 and 149 are in the order of 192 pages to 1 page in order from the bottom, and in this state, are sent to the next process such as collation.

  Note that if the cutting register adjustment is not completed at the time when the distribution by the distribution cam 171 is started, the folding book 67 whose cutting position does not match the pattern (not a product) is the lower impeller 51 or the upper impeller 53. However, since these folding sheets 67 are not likely to clog the lower impeller 51 or the upper impeller 53, they should be discharged downstream of the lower impeller 51 or the upper impeller 53. That's fine. In this case, the fixing control unit 203 stops the return of the sorting direction fixing device 181 and the branching unit 151 until the cutting registration adjustment is completed, and continues to discharge the signature 67 whose cutting position does not match the pattern to the discharge box 163. It may be.

In this way, the fixed control unit 203 automatically discharges the signature 67 at the low speed when the folding accuracy is not stable out of the path, thereby preventing the signature 67 from clogging the lower impeller 51 or the upper impeller 53. Therefore, it becomes unnecessary to arrange a worker, and the operation cost can be reduced accordingly.
Further, since the moving origami 67 is not removed by hand, it is possible to prevent a worker from being injured.

In addition, the fixed control unit 203 is operated according to a predetermined sequence. However, a manual sequence is added, and the sorting direction fixing device 181 and the branching unit 151 are operated even when the state of the signature 67 is observed. You may do it.
Furthermore, the fixed control unit 203 includes a detector that detects a signature that may be clogged with the impeller, for example, a detector that detects that the end in the width direction of the signature 67 is located outside the conveyance path. You may make it operate the distribution direction fixing device 181 and the branch part 151 with the detection signal of a detector.

In addition, this invention is not limited to this embodiment, In the range which does not deviate from the summary of this invention, it can change suitably.
For example, in the present embodiment, the present invention is applied to the rotary printing press 1 that stacks and discharges a plurality of folding sheets 67. However, the present invention is not limited to this, and is disclosed in JP-A-63-208468. It may be applied to a rotary printing machine in which such a folded book is partly sorted, tiled and discharged.
Further, although the timing detection device 195 detects a portion where the shape of the sorting cam 171 changes, the timing detection device 195 may be configured to track the conveyance position of the signature 67.
