The paper feed unit 16 supplies the printing paper P stacked on the paper feed tray 17 to the transport device 9 of the printer main body 1 one by one from the top. The paper size sensor 24 detects the horizontal width WS and the vertical width WL of the paper P on the paper feed tray 17.

  In the printing machine main body 1, a printing unit 5 is provided at a substantially middle portion in the front-rear direction, a plate making device 6 is provided above the printing unit 5, and a plate discharging device 7 is provided above the printing unit 5. A conveyance device 9 and a timing roller 26 are provided between the paper feeding device 2 and the printing unit 5, and a paper discharge device 8 is provided between the printing unit 5 and the paper receiving device 3. .

  The printing unit 5 includes a printing plate cylinder 11 in which an ink supply roller 10 is inscribed and rotationally driven in the direction of an arrow R, and a vertically movable pressing roller 12 that faces the printing plate cylinder 11 so as to come into contact with the printing plate cylinder 11 from below. And printing is performed on the upper surface of the printing paper P between the printing plate cylinder 11 and the pressing roller 12.

  The paper discharge device 8 includes an air suction belt conveyance mechanism 27, a U-shaped width guide mechanism 28 disposed at the front of the air suction belt conveyance mechanism 27, and a paper passage sensor 29. The air suction type belt conveyance mechanism 27 is composed of a plurality of rows of paper discharge belts 30, a suction box 31, and a suction fan 32 in the left-right direction, and the printing paper P is fed by the air suction action of the suction fan 32. It is adsorbed on the paper discharge belt 30 and is conveyed in the conveyance direction F. The paper passage sensor 29 detects the presence or absence of paper that passes through the U-shaped formation width guide mechanism 28.

  The paper receiver 3 includes a paper receiver 40, a U-shaped state holding member 49 provided on the paper receiver 40, and a pair of width guides 50 disposed on both sides in the left-right direction above the paper receiver 40. 60, and longitudinal guides 70 and 80 disposed on both sides in the front-rear direction above the paper tray 40.

  The operation panel 120 includes a display output unit 121 and an operation input unit 122. The display output unit 121 is a display. The operation input unit 122 includes a key and a dial. The user can input various set values and print commands to the stencil printing machine via the operation input unit 122.

  In FIG. 2, the center line between the left and right lateral width guides 13 on the sheet feeding device 2 is denoted by reference numeral O1, and the center line of the left and right width of the printing plate cylinder 11 in the printing machine body 1 is denoted by reference numeral O2. In addition, a center line between the left and right U-shaped holding members 49 of the paper receiving apparatus 2 is indicated by a symbol O3, and a horizontal center line of the paper P is indicated by a symbol OP. The center lines O1, O2, and O3 in the stencil printing machine are aligned on the same straight line. In particular, the sheet P is transported so that the left and right center line OP of the sheet P coincides with the center lines O1, O2, and O3 in the stencil printing machine.

  The paper P is rectangular and has a vertical width WL and a horizontal width WS. In the paper feeder 2, the paper P is kept flat. The vertical width WL of the paper P is defined with reference to the direction in which the paper P is conveyed. That is, the vertical width WL is the length of the paper P in the front-rear direction of the paper feeder 2, and the horizontal width WS is the length of the paper P in the left-right direction of the paper feeder 2. The horizontal width WS may be longer than the vertical width WL.

  In the paper feeding device 2, the interval between the left and right lateral width guides 13 is D0. The interval D0 matches the horizontal width WS of the paper P. That is, the paper P between the lateral width guides 13 is kept flat. The paper P is conveyed in a flat state until it reaches the U-shaped formation width guide mechanism 28. On the other hand, the paper P is bent in the width direction by the U-shaped width guide mechanism 28 and bent into a U-shape when viewed from the front. Hereinafter, a state in which the sheet P is bent in a U shape when viewed from the front-rear direction is referred to as a “U-shaped state”. In the paper receiving device 3, the distance between the left and right width guides 50, 60 is D1. The interval D1 is smaller than the interval D0. That is, the paper P between the lateral width guides 50 and 60 is kept in a U-shape. The U-shaped formation width guide mechanism 28 and the paper receiving device 3 will be described in detail below.

  FIG. 3 shows an example of the U-shaped formation width guide mechanism 28 of the paper discharge device 8. The U-shaped formation width guide mechanism 28 is provided on a pair of left and right lifting width guide portions 33 disposed along the upper surface (paper conveyance surface) of the paper discharge belt 31 and on both sides of each lifting width guide portion 33 in the left and right direction. And a pair of left and right narrowing width guide portions 34 provided. The narrowing width guide portion 34 can be omitted.

  The lifting width guide portion 33 is formed in a triangular pyramid shape, and when viewed from the side, the lifting width guide portion 33 becomes higher at a predetermined angle from the rear end 33a having a height substantially matching the upper surface of the paper discharge belt 21 toward the front side. The end side front end 33b is the highest. Further, when viewed from the front, the height increases from the central front end 33c toward the side end front end 33b. Further, the lifting width guide portion 33 is formed so that the left and right widths increase toward the front when viewed from above.

  For this reason, when the paper P passes through the U-shaped width guide mechanism 28, the left and right end portions of the paper P are gradually lifted by the lifting width guide portion 33 while the central portion of the paper P is sucked by the suction belt 31. Lifted to. Accordingly, the sheet P is discharged forward (F) from the U-shaped width guide mechanism 28 in a state where the entire sheet P is deformed into an upward U-shape. By passing through the U-shaped formation width guide mechanism 28, the paper P is bent so as to be U-shaped when viewed from the front-rear direction.

  The sheet P is U-shaped after passing through the U-shaped formation width guide mechanism 28. For this reason, the lateral width of the paper P bent into a U-shape is different from the lateral width WS of the paper P in a flat state. Hereinafter, the width WS refers to the length in the left-right direction of the paper P in a flat state (a state in a single plane). In other words, the horizontal width WS in a flat state corresponds to the length of a curve drawn by the U-shaped paper P viewed from the front-rear direction.

(Configuration of the first embodiment)
FIG. 4 is a front view of the paper receiving device 3 of the first embodiment. The paper receiving device 3 of the first embodiment is a paper receiving table type. The paper receiving tray type means a paper receiving apparatus of a type in which width guides 50, 60, and 70 that are movable in the horizontal direction are supported by the paper receiving tray 40. In the paper cradle type, the vertical position of the paper cradle 40 is fixed. That is, the paper tray 40 does not move in the vertical direction with respect to the movable width guides 50, 60, and 70. For this reason, the paper P can be stacked within the range of the vertical width of the width guides 50, 60 and 70.

  The paper receiver 3 generally stacks the paper P on the paper receiver 40 as follows. The paper P discharged from the stencil machine main body 1 (U-shaped formation width guide mechanism 28) starts dropping from above the paper tray 40, and then a pair of left and right lateral guides 50, 60 and a pair of front and rear longitudinal guides. It passes between 70 and 80 and reaches the upper surface of the paper tray 40 and the U-shaped state holding member 49. When the paper P falls one after another, the laminated body A of the paper P is formed on the paper cradle 40 and the U-shaped state holding member 49.

  The paper receiving device 3 includes drive motors 51 and 61 and transmission mechanisms 52 and 62 as lateral drive devices for moving the movable width guides 50 and 60 in the left-right direction, respectively. The paper receiving device 3 includes a drive motor 71 and a transmission mechanism 72 as a vertical drive device that moves the movable vertical guide 70 in the front-rear direction. The paper receiving device 3 includes a control unit 301, a storage unit 302, and a connection device 303.

  The lateral width guides 50, 60 in the left-right direction are erected in a substantially vertical posture with respect to the upper surface of the paper tray 40, and are movable in the left-right direction, and are driven motors via transmission mechanisms 52, 62, respectively. 51 and 61, and can be moved individually in the left-right direction.

  The longitudinal width guides 70, 80 in the front-rear direction are erected in a substantially vertical posture with respect to the upper surface of the paper tray 40. The vertical width guide 80 is fixed, but the vertical width guide 70 is movable in the front-rear direction. The vertical width guide 70 is connected to the drive motor 71 via a transmission mechanism 72 and can move in the front-rear direction.

  The control unit 301 can control the positions of the horizontal width guides 50 and 60 and the vertical width guide 70 independently by controlling the drive motors 51, 61 and 71. In particular, the control unit 301 controls the positions of the width guides 50, 60, and 70 based on the horizontal width WS and vertical width sL of the paper P and the occurrence of a new paper P falling.

  The storage unit 302 includes a reference horizontal adjustment width AS0, a first horizontal adjustment width AS1, a second horizontal adjustment width AS2, a first horizontal fluctuation width VS1, a second horizontal fluctuation width VS2, a reference vertical adjustment width AL0, and a first vertical adjustment width. AL1, first longitudinal fluctuation range VL1, first frequency f1, second frequency f2, and third frequency f3 are stored. These values are set values used in controlling the movable width guides 50, 60, and 70.

  The set value can be changed by the following configuration. The user can input a setting value change command by operating the operation input unit 22. The change command is a command for changing at least one set value. The input change command is transmitted to the control unit 301 via the control unit 100 and the connected device 303. The control unit 301 changes each set value stored in the storage unit 302 based on the change command. Here, the connected device 303 corresponds to a “change command acquisition unit” that acquires a change command for changing at least one of all set values in the paper receiving device 3.

  The storage unit 302 can store a plurality of set value sets. Each set value set is a set of all set values and includes a reference lateral adjustment width AS0, a first lateral adjustment width AS1, a second lateral adjustment width AS2, a first lateral fluctuation width VS1, and a second lateral fluctuation width VS2. , A reference vertical adjustment width AL0, a first vertical adjustment width AL1, a first vertical fluctuation width VL1, a first frequency f1, a second frequency f2, and a third frequency f3. Each set value set is set for each of different types and / or different widths. The type means a type of the paper P that is different in terms of rigidity, and indicates a difference in thickness and material of the paper P. The user can input a setting value set designation command by operating the operation input unit 22. The designation command is a command for specifying a set value set used in the control of the width guides 50, 60, and 46. The input designation command is transmitted to the control unit 301 via the control unit 100 and the connected device 303. The control unit 301 specifies a set value set used in the next control based on the designation command. The designation command includes the width WS of the paper P and the type information. Here, the connected device 303 corresponds to a “type information acquisition unit” that acquires information on the type of the paper P in the paper receiving device 3.

  The control unit 301 can acquire information that a new sheet P has dropped toward the sheet receiving tray 40 with the following configuration. As described above, the paper passage sensor 29 can detect the paper P passing through the U-shaped width guide mechanism 28. Here, the detection of the paper P by the paper sensor 29 means that the paper P newly falling toward the paper receiving tray 40 has occurred. A detection signal from the paper passage sensor 29 is transmitted to the control unit 301 via the control unit 100 and the connected device 303. Here, the connection device 303 corresponds to a “fall information acquisition unit” that acquires information that a new sheet P has dropped toward the paper tray 40 in the paper receiver 3. Note that the fall information acquisition unit can be a sensor that can detect the fall of a new paper P in the paper receiver 3. In this case, the sensor is disposed on the paper P dropping path in the paper receiving device 3.

  The control unit 301 can acquire information on the horizontal width WS and the vertical width WL of the paper P with the following configuration. The paper P supplied to the paper receiver 3 is a paper that has been supplied from the paper feeder 2 and has undergone a printing process in the stencil machine body 1. As described above, the paper size sensor 24 can detect the widths WS and WL of the paper P in the paper feeder 2. A detection signal from the paper passage sensor 29 is transmitted to the control unit 301 via the control unit 100 and the connected device 303. Here, in the paper receiving apparatus 3, the connected device 303 includes a “width information acquisition unit” that acquires information about the width of the paper P, and a “length information acquisition unit” that acquires information about the height WL. Equivalent to.

  The U-shaped state holding member 49 is arranged symmetrically with respect to the center line O3, and is arranged with a space in the front-rear direction. The U-shaped state holding member 49 is formed in a triangular shape that rises outward from the center line O3 in the left-right direction.

  In FIG. 5, each U-shaped state holding member 49 is rotatably supported at the end on the center O3 side in the left-right direction by the paper receiving tray 40 via a rotation shaft 49a. Each U-shaped state holding member 49 can change an inclination angle θ <b> 1 with respect to the upper surface of the paper receiving tray 40 by rotating around a rotation shaft 49 a. That is, the inclination angle θ1 can be reduced when stacking thick paper with high rigidity, and the inclination angle paper θ1 can be set large when stacking thin paper with low rigidity.

(Operation of the first embodiment)
With the operation of the stencil printing machine, the paper receiving device 3 is also operated. Specifically, the following procedure is executed. First, the user inputs a print command to the control unit 100 of the stencil machine body 1 through the operation of the operation panel 120. At this time, the user also inputs the size and orientation of the paper P to be printed, such as the standard A4 size side. The size and orientation mean the horizontal width WS and the vertical width WL. For this reason, the control unit 100 can specify the horizontal width WS and the vertical width WL for the paper P specified in the print command. Further, the control unit 100 can detect the size and orientation of the paper P on the paper feed tray 17 of the paper feed device 2 using the paper size sensor 24. The control unit 100 confirms whether the paper P specified in the print command and the paper P on the paper feed tray 17 are the same in terms of size and orientation.

  If the designated paper P and the paper P on the paper feed tray 17 are the same, the control unit 100 starts the printing process. In addition, the control unit 100 transmits the confirmed horizontal width WS and vertical width WL of the paper P to the control unit 301.

  When the printing process is started, the paper feeding device 2 supplies the paper P to the printer main body 1. The paper P is supplied to the paper receiving device 3 after being printed by the printer main body 1. When the print command instructs a plurality of print processes, when one print process is completed, the next one print process is started.

  Since the paper P supplied to the paper receiving device 3 passes through the U-shaped width guide mechanism 28, the paper P falls to the paper receiving device 3 while being bent in a U shape when viewed from the front-rear direction. After passing through the U-shaped width guide mechanism 28, the U-shaped paper P reaches between the left and right width guides 50 and 60 and between the front and rear width guides 70 and 80. Then it falls down.

  On the other hand, before the printed paper P is supplied to the paper receiving device 3 with the start of the printing process, the control unit 301 adjusts the interval between the left and right horizontal guides 50 and 60 according to the paper P, and the front and rear. The distance between the vertical width guides 70 and 80 is adjusted.

  As shown in FIG. 5, the control unit 301 moves the horizontal width guides 50 and 60 to the horizontal reference positions P50 and P60, respectively, so that the distance between the left and right horizontal width guides 50 and 60 becomes the reference distance D1. Here, the positions of the lateral width guides 50 and 60 accurately indicate the positions of the guide surface 50a of the lateral width guide 50 and the guide surface 60a of the lateral width guide 60. The guide surfaces 50a and 60a are vertical surfaces with which the paper P contacts in the lateral width guides 50 and 60. The reference interval D1 is an interval smaller than the acquired lateral width WS by the reference lateral adjustment width AS0 (D1 = WS−AS0). That is, the interval between the lateral width guides 50 and 60 is slightly smaller than the lateral width WS. For this reason, the paper P falling between the lateral width guides 50 and 60 is maintained in a U shape.

  As shown in FIG. 6, the control unit 301 moves the vertical width guide 70 to the vertical reference position P <b> 70 so that the interval between the front and rear vertical width guides 70 and 80 becomes the vertical width WL. The positions of the vertical width guides 70 and 80 also accurately indicate the positions of the guide surface 70 a of the vertical width guide 70 and the guide surface 80 a of the vertical width guide 60.

  In FIG. 5, the control unit 301 executes the catch prevention control during the execution of the printing process. The catch prevention control is control for preventing the sheet P from being caught on the lateral width guides 50 and 60.

  In the catch prevention control, the control unit 301 vibrates the lateral width guides 50 and 60 at the second frequency f2 within the range of the second lateral variation width VS2 including the lateral reference positions P50 and P60.

  In FIG. 5, the second lateral fluctuation width VS2 in the lateral width guide 50 is set with the lateral reference position P50 and the outer position P502a as both ends. The second lateral variation width VS2 in the lateral width guide 60 is set with the lateral reference position P60 and the outer position P602a as both ends. The outer position P502a is located on the left side of the horizontal reference position P50, and the outer position P602a is located on the right side of the horizontal reference position P50. Further, the second lateral fluctuation width VS2 is described with a relatively large width for convenience of illustration. However, the second lateral fluctuation width VS2 is, for example, about 0.5 mm. Accordingly, the second lateral fluctuation width VS2 is considerably smaller than at least the reference interval D1 by about several tens of centimeters. The second frequency f2 is, for example, 20 Hz (times / second). At this time, the lateral width guides 50 and 60 reciprocate 20 times within the range of the second lateral variation width VS2 per second.

  Further, the control unit 301 executes horizontal jogger operation control and vertical jogger operation control each time the paper P is supplied to the paper feeding device 3 during execution of the printing process. The horizontal jogger operation control and the vertical jogger operation control are controls for aligning the left and right positions and the front and rear positions of the laminate A, respectively.

  In the lateral jogger operation control, the control unit 301 moves the lateral width guides 50 and 60 within a range of the first lateral variation width VS1 including the lateral reference positions P50 and P60 for a predetermined time according to the occurrence of the falling paper P. The reciprocating motion is performed at the first frequency f1.

  In FIG. 5, the moving range of the lateral width guide 50 is the first lateral variation width VS1 having both the lateral reference position P50 and the outer position P501a as both ends. The moving range of the lateral width guide 60 is the first lateral variation width VS1 having the lateral reference position P60 and the outer position P601a as both ends. The outer position P501a is located on the left side of the horizontal reference position P50, and the outer position P601a is located on the right side of the horizontal reference position P50. Further, the first lateral fluctuation range VS1 extends to the outside of the lateral width WS. When the first lateral variation width VS1 extends to the outside of the lateral width WS, the lateral width guides 50 and 60 for suppressing the paper P instantaneously expand beyond the lateral width WS. For this reason, the first lateral fluctuation range VS1 may be set only inside the lateral width WS. Further, the first lateral fluctuation range VS1 is sufficiently larger than the second lateral fluctuation range VS2.

  In the vertical jogger operation control, the control unit 301 moves the vertical width guide 70 within a range of the first vertical fluctuation width VL1 including the vertical reference position P70 for a predetermined time according to the occurrence of the falling paper P. Reciprocating at frequency f3.

  In FIG. 6, the moving range of the vertical width guide 70 is the first vertical fluctuation width VL1 having both the vertical reference position P70 and the outer position P701a as both ends. The outer position P701a is located on the front side of the vertical reference position P70.

  The horizontal jogger operation control and the vertical jogger operation control may be executed every time a new sheet P is added to the laminate A. For this reason, the execution start timing of the jogger operation control can be set to an arbitrary timing as long as it is between the previous occurrence time of the fall of the paper P and the next occurrence time of the fall of the paper P.

  The number of times the width guides 50, 60, and 70 reciprocate in the horizontal jogger operation control and the vertical jogger operation control is, for example, one. This number of times may be two or more. In addition, after the end of execution of the jogger operation control, the width guides 50, 60, and 70 always return to the initial positions (P50, P60, P70).

  The lateral width guides 50 and 60 are shared in lateral jogger operation control and catch prevention control. For this reason, the execution time and execution timing of the lateral jogger operation control can interfere with the execution time and execution timing of the catch prevention control. Therefore, the execution time of the lateral jogger operation control is set so as to be always shorter than the time width from the previous drop time to the current drop time. In this way, the execution time of the hook prevention control is secured. Therefore, accurately, the catch prevention control is executed except during execution of the lateral jogger operation control during execution of the printing process. Further, due to the difference in properties between the lateral jogger operation control and the catch prevention control, the second lateral fluctuation width VS2 is smaller than the first lateral fluctuation width VS1, and the second frequency f2 is larger than the first frequency f1.

  When a predetermined time elapses after all the printing processes are completed in the printer main body 1, the control unit 301 ends the catch prevention control.

  When the storage unit 302 stores a plurality of setting value sets, if the user designates the width WS and the type of the paper P, the corresponding setting value set is determined according to the designated width WS and the type of the paper P. Automatically selected. Then, based on the set values (AS0, AS1, AS2, VS1, VS2, AL0, AL1, VL1, f1, f2, and f3) included in the set value set, the lateral jogger operation control and the catch prevention control are executed. Is done. Here, the width WS is inevitably specified when the user inputs a print command. When the user wants the paper receiving apparatus 3 to perform control corresponding to the type of the paper P, the user needs to input the type of the paper P when inputting the print command.

  Further, the user can arbitrarily change each set value (AS0, AS1, AS2, VS1, VS2, AL0, AL1, VL1, f1, f2, and f3) by inputting a set value change command. Therefore, the user can appropriately change one or a plurality of setting values according to, for example, difficulty in bending the paper due to a difference in paper type.

  As a case where the type of the paper P is different from normal, the paper P may be a thick paper. In this case, since the rigidity of the paper P is higher than usual, a stronger force can be applied to the laminate A in the jogger operation. As the horizontal jogger operation corresponding to the thick paper, for example, the movement range of the horizontal width guides 50 and 60 in the jogger operation is changed.

  FIG. 7 shows a case where the lateral width guides 50 and 60 are moved to the inside of the lateral reference positions P50 and P60 in the lateral jogger operation. The movement range of the lateral width guide 50 is the first lateral variation width VS1 having both the inner position P501b and the outer position P501a as both ends. The inner position P501b is a position that is on the inner side by the first lateral adjustment width AS1 than the lateral reference position P50. Similarly, the moving range of the lateral width guide 60 is the first lateral variation width VS1 having both the inner position P601b and the outer position P601a as both ends. The inner position P601b is a position that is on the inner side by the first lateral adjustment width AS1 than the lateral reference position P60. In other words, the movement range of the horizontal width guides 50 and 60 in FIG. 7 is set as a whole inside the movement range of the horizontal width guides 50 and 60 in FIG. In addition, the movement range of the width guides 50 and 60 in FIG. 5 is a case where AS1 = 0.

  By changing the set value, the moving range of the horizontal width guides 50 and 50 in the catching prevention control and the moving range of the vertical width guide 70 in the vertical jogger operation can also be changed.

  In FIG. 7, the movement range of the lateral width guide 50 in the catching prevention control is the first lateral variation width VS2 having both the inner position P502b and the outer position P502a as both ends. The inner position P502b is a position that is on the inner side by the second lateral adjustment width AS2 than the lateral reference position P50. Similarly, the movement range of the lateral width guide 60 in the catching prevention control is the second lateral variation width VS2 having both the inner position P602b and the outer position P602a as both ends. The inner position P602b is a position that is on the inner side by the second lateral adjustment width AS2 than the lateral reference position P60. When AS2 = 0, the inner positions P502b and P602b are equal to the lateral reference positions P50 and P60, respectively.

  In FIG. 8, the moving range of the vertical width guide 70 in the vertical jogger operation is the first vertical fluctuation width VL1 having both the inner position P701b and the outer position P701a as both ends. The inner position P701b is a position that is on the inner side by the first vertical adjustment width AL1 than the vertical reference position P70. When AL1 = 0, the inner position P701b is equal to the vertical reference position P70.

(Operation and effect of the first embodiment)
In 1st Embodiment, the laminated body A can be aligned in the left-right direction by horizontal jogger operation control. Further, since the pair of lateral width guides 50 and 60 vibrate due to the hooking prevention control, the paper P is reliably dropped without being caught between the pair of lateral width guides 50 and 60. For this reason, the fall of the following paper P is not stopped by the paper P in which the fall was interrupted. Therefore, it is possible to prevent defects in the stacking of the sheets P.

  In the first embodiment, the set values (AS0, VS1, VS2, AL0, VL1, f1, f2, and f3) can be changed. For this reason, depending on the width WS of the paper P and the type of the paper P, the paper P can be appropriately prevented from being caught, and the stacked bodies A can be appropriately aligned in the left-right direction.

  In the first embodiment, set values (AS 0, VS 1, VS 2, AL 0, VL 1, f 1, f 2, and f 3) are set for each horizontal width WS of paper P and / or each type of paper P. Therefore, the jogger operation and the catch prevention control suitable for the width and type suitable for the width WS and type can be executed only by specifying the width WS and type.

  In 1st Embodiment, the laminated body A can be arrange | equalized in the front-back direction further by vertical jogger operation control.

(Second Embodiment)
The paper receiving device 3 according to the second embodiment is different from the first embodiment in the shape of the width guides 50 and 60. In other respects, the second embodiment and the second embodiment are the same.

  As shown in FIG. 9, the left and right lateral width guides 50 and 60 have lower guide surfaces 50a and 60a and upper guide surfaces 50b and 60b, respectively. The upper guide surfaces 50b and 60b are on the inner side (center line O3 side) of the lower guide surfaces 50a and 60a in the left-right direction. The paper P can be stacked in a range from the upper ends of the lower guide surfaces 50a and 60a to the upper surface of the paper tray 40.

  In the lateral width guides 50 and 60 of the second embodiment, the target site for position control is the position of the lower guide surfaces 50a and 60a. In the second embodiment, the distance between the lower guide surfaces 50a and 60a and the position of the lower guide surfaces 50a and 60a are controlled in the same manner as in the first embodiment.

(Third embodiment)
FIG. 10 is a front view showing the paper receiving device 3 of the third embodiment. The paper receiving device 3 of the third embodiment is a top plate type. The top plate type means a paper receiving device of a type in which movable width guides 50, 60 and 70 are supported by a top plate 90 arranged above the paper receiving tray 40. Here, the vertical position of the top plate 90 is fixed. In the top plate type, the vertical position of the paper tray 40 can be changed. That is, the paper tray 40 moves in the vertical direction with respect to the movable width guides 50, 60, and 70. For this reason, the paper P can be stacked within a range exceeding the vertical width of the width guides 50, 60 and 70. When the height of the stacked body A exceeds the vertical width of the width guides 50, 60, and 70, the width guides 50, 60, and 70 restrict only the upper part of the stacked body A in the horizontal direction.

  The paper receiving device 3 of the third embodiment is the first in the presence of the top plate 90, the point where the top plate 90 supports the width guides 50, 60, 46, and the point where the paper receiving table 40 moves up and down. It differs from the paper receiving device 3 of the embodiment. In other respects, the third embodiment and the first embodiment are the same.

  The paper receiver 3 of the third embodiment includes a drive motor 41, a transmission mechanism 42, and a level sensor 43 in order to control the paper receiver 40 (height of the laminate A). The paper tray 40 is connected to a drive motor 41 via a transmission mechanism 42. Further, the level sensor 43 detects the presence or absence of the laminate A below the predetermined distance H from the bottom surface of the top plate 90. When the level sensor 43 detects the stacked body A, the control unit 301 controls the drive motor 41 so that the paper tray 40 is lowered by a predetermined width. In this way, as the stacked body A becomes higher, the paper tray 40 is lowered, and the distance between the stacked body A and the bottom surface of the top plate 90 is always kept at a predetermined distance H or more.

(Operation and effect of the third embodiment)
In the third embodiment, the level sensor 43 is provided to control the vertical movement of the paper tray 40, but the catch of the paper P between the lateral width guides 50 and 60 is prevented by the catch prevention control. . Here, if the paper P caught by the level sensor 43 is detected, the detection state by the level sensor 43 continues even if the paper receiving tray 40 is lowered accordingly. In such a case, the paper receiving tray 40 continues to descend, or the control unit 100 that regards the continued detection state as jam detection interrupts the printing process. In the third embodiment, since the level sensor 43 is prevented from detecting the paper P that is caught, there is no problem that the paper tray 40 continues to descend or the printing process is interrupted.

(Fourth embodiment)
FIG. 10 is a front view showing the paper receiving device 3 of the fourth embodiment. The paper receiving device 3 of the fourth embodiment is the same as that of the third embodiment except for the shape of the lateral width guides 50 and 60. The shape of the width guides 50 and 60 of the fourth embodiment is the same as the shape of the width guides 50 and 60 of the second embodiment.

The paper receiving device 3 of the fifth embodiment is also a top plate type. Hereinafter, the same reference numerals are given to the same parts and portions between the fifth embodiment and the first embodiment.

  In particular, the paper receiving device 3 of the fifth embodiment is the same as the paper receiving device 3 of the third embodiment except for the differences in the width guide. The paper receiving device 3 of the third embodiment includes a set of horizontal width guides (a set of 50 and 60), whereas the paper receiving device 3 of the fifth embodiment includes two sets of horizontal width guides (a set of 150 and 160).

Each of the four lateral width guides 150, 160, 250, and 260 is configured to be movable in the horizontal direction. The first lateral guides 150 and 160 are used in lateral jogger operation control, and the second lateral guides 250 and 260 are used in catch prevention control.

  As shown in FIG. 14, the paper receiving device 3 of the fifth embodiment includes a drive motor 151, 161, 251, and 261, a transmission mechanism 152, and a control unit for controlling the width guides 150, 160, 250, and 260. 162, 252 and 262. The control unit 301 can independently control the positions of the width guides 150, 160, 250, and 260 by controlling the drive motors 151, 161, 251, and 261. The position of the width guides 150, 160, 250, and 260 accurately refers to the position of the guide surfaces 150a, 160a, 250a, and 260a of the width guides 150, 160, 250, and 260.

  FIG. 15 is a perspective view showing a drive mechanism of the first lateral width guide 160 in the fifth embodiment. The transmission mechanism 162 includes a linear guide mechanism using a lateral guide rail 163, a belt transmission mechanism 164, and a belt type speed reduction mechanism 165. The first lateral guide 160 is supported by the linear guide mechanism so as to be movable in the left-right direction with respect to the top plate 90. The power of the drive motor 161 is decelerated by the belt type reduction mechanism 165 and then transmitted to the belt transmission mechanism 164 to move the first lateral guide 160 in the left-right direction.

  FIG. 16 is a perspective view showing a drive mechanism of the second width guide 260 in the fifth embodiment. The transmission mechanism 262 includes a linear guide mechanism using a lateral guide rail 263, a belt transmission mechanism 264, and a belt type speed reduction mechanism 265. The second lateral width guide 260 is supported by the linear motion guide mechanism so as to be movable in the left-right direction with respect to the top plate 90. The power of the drive motor 261 is decelerated by the belt type reduction mechanism 265 and then transmitted to the belt transmission mechanism 264 to move the second lateral guide 260 in the left-right direction.

  As shown in FIG. 17, the second lateral width guides 250 and 260 have lower guide surfaces 250a and 260a and upper guide surfaces 250b and 260b, respectively. The upper guide surfaces 250b and 260b are on the inner side (center line O3 side) of the lower guide surfaces 250a and 260a in the left-right direction. In addition, the guide surfaces 150a and 160a of the first lateral guides 150 and 160 are below the guide surfaces 250b and 260b of the second lateral guides 250 and 260. The guide surfaces 150a, 160a, 250a, 250b, 260a, and 260b are all surfaces on which the paper P comes into contact and are vertical surfaces.

(Operation of the fifth embodiment)
The operations of the stencil machine main body 1 and the paper feeder 2 are the same in the fifth embodiment and the first embodiment. Therefore, the operation of the paper receiving device 3 in the fifth embodiment will be mainly described below.

  The control unit 100 of the stencil machine main body 1 specifies the horizontal width WS and the vertical width WL of the paper P to be printed based on the print command input by the user. For this reason, the control unit 100 transmits the horizontal width WS and the vertical width WL of the paper P to be printed to the control unit 301 via the connection device 303.

The control unit 301 adjusts the interval between the left and right first width guides 150 and 160 according to the paper P before the printed paper P is supplied to the paper receiving device 3 with the start of the printing process. The interval between the second horizontal guides 250 and 260 and the interval between the front and rear vertical guides 70 and 80 are adjusted.

  As shown in FIG. 17, the control unit 301 moves the first lateral guides 150 and 160 to the lateral reference positions P50 and P60, respectively, so that the spacing between the left and right guide surfaces 150a and 160a becomes the reference spacing D1. . In addition, the control unit 301 moves the second lateral guides 250 and 260 to the lateral reference positions P50 and P60, respectively, so that the spacing between the left and right lower guide surfaces 250a and 260a becomes the reference spacing D1.

  Similarly to FIG. 8, the control unit 301 moves the vertical width guide 70 to the vertical reference position P70 so that the distance between the front and rear guide surfaces 70a and 80a becomes the vertical width WL.

  In FIG. 17, the control unit 301 executes the catch prevention control during the execution of the printing process. The catch prevention control is control for preventing the sheet P from being caught on the second lateral guides 250 and 260. In the catch prevention control, the control unit 301 vibrates the second lateral width guides 250 and 260 at the second frequency f2 within the range of the second lateral variation width VS2 including the lateral reference positions P50 and P60.

  Further, the control unit 301 executes horizontal jogger operation control and vertical jogger operation control each time the paper P is supplied to the paper feeding device 3 during execution of the printing process. The horizontal jogger operation control and the vertical jogger operation control are controls for aligning the left and right positions and the front and rear positions of the laminate A, respectively. In the lateral jogger operation control, the control unit 301 moves the first lateral width guides 150 and 160 within a range of the first lateral variation width VS1 including the lateral reference positions P50 and P60 for a predetermined time according to the occurrence of the falling paper P. The reciprocating motion is performed at the first frequency f1. Similarly, in the vertical jogger operation control, the control unit 301 moves the vertical width guide 70 within a range of the first vertical fluctuation width VL1 including the vertical reference position P70 for a predetermined time according to the occurrence of the falling paper P. The reciprocating motion is performed at the third frequency f3.

  In the fifth embodiment, the first lateral guides 150 and 160 are in charge of lateral jogger operation control, and the second lateral guides 250 and 260 are in charge of catching prevention control. For this reason, the execution time and execution timing of the lateral jogger operation control never interfere with the execution time and execution timing of the catch prevention control. Therefore, there is no problem even if the catch prevention control is executed during the execution of the lateral jogger operation control.

  When a predetermined time elapses after all the printing processes are completed in the printer main body 1, the control unit 301 ends the catch prevention control.

  Also in the fifth embodiment, the movement range of the width guides 150, 160, 250, 260, and 70 in the jogger operation control and the catch prevention control can be changed by changing the set value.

  FIG. 18 shows the movement range of the first lateral guides 150 and 160 in the lateral jogger operation control suitable for thick paper. The moving range of the horizontal width guides 150 and 160 in FIG. 18 is set inside as a whole than the moving range of the horizontal width guides 50 and 60 in FIG.

(Operations and effects of the fifth embodiment)
In 5th Embodiment, the laminated body A can be aligned in the left-right direction by horizontal jogger operation control. Further, since the pair of second width guides 250 and 260 vibrate due to the hook prevention control, the paper P reliably falls without being caught between the pair of second width guides 250 and 260. For this reason, the fall of the following paper P is not stopped by the paper P in which the fall was interrupted. Therefore, it is possible to prevent defects in the stacking of the sheets P. Furthermore, since there are two independent pairs of left and right guides, that is, the first lateral guides 150 and 160 and the second lateral guides 250 and 260, the lateral jogger operation control and the catch prevention control can be set independently.
