BACKGROUND OF THE INVENTION
  According to the present invention, a relatively small size printed matter such as a card, a postcard, an envelope or the like having a certain level of stiffness is placed at a predetermined interval into a storage portion provided at the upper portion of the apparatus main body while holding both side edges. Transfer and store while openingPrinted paper discharge storage device suitable forAbout.

[Prior art]
  2. Description of the Related Art A stencil printing apparatus that optically reads an original, performs digital perforation on a thermal stencil master with a thermal head, and wraps the master made on a printing drum to perform printing is well known. When a printed material on which an image has been printed by such a stencil printing apparatus is stacked on a paper discharge tray, the printed material discharged next is superimposed on the image surface of the previously discharged printed material. When the sheets are stacked in a state, a so-called set-off phenomenon in which the ink on the image surface of the printed matter that has been discharged first adheres to the back surface of the printed matter that has been discharged later easily occurs.
[0003]
  Therefore, in order to prevent this set-off, printing is not performed every time the printing drum of the printing apparatus is rotated once, but is fed every several to several tens of times, so that the previously discharged printed matter is dried. There is an intermittent paper feed type in which the next printing is performed after this, but in such a printing apparatus, the printing drum is idled and printing is not performed until the ink is dried. There was a problem that it took a long time. For this reason, the prints are prevented from being set off by transporting and stacking them in the storage unit provided above the apparatus over a period of time without overlapping each other.Printed paper discharge storage deviceThe applicant has previously filed Japanese Patent Application Laid-Open No. 8-175734.
[0004]
  thisPrinted paper discharge storage deviceThe two sides of the printed matter that is printed and discharged by a stencil printing machine or the like are held by receiving portions that are respectively formed on each of four upright coil spring-like conveyance bodies with predetermined intervals in the vertical direction. By rotating the respective conveying members in the state, the printed matter is transferred and stacked in a storage unit above the apparatus. Accordingly, since the printed materials are respectively held in the receiving portions of the respective transport bodies and are sequentially stacked on the storage portion with an interval in the vertical direction, it is possible to prevent set-off.
[0005]
  thisPrinted paper discharge storage deviceWhen a printed matter discharged from the stencil printing apparatus is received, if it is in an unsuitable conveyance position, it can be detected by a sensor. When this unsuitable transport position is detected,Printed paper discharge storage deviceThe control means provided in the system stops each drive system.
[0006]
[Problems to be solved by the invention]
  However, such conventionalPrinted paper discharge storage deviceIn this case, when the printed material received from the stencil printing apparatus is in the unsuitable conveyance position, each drive system is stopped, so that it is possible to prevent subsequent printed materials from continuing to be poorly conveyed. I could not immediately know what caused the conveyance failure.
[0007]
  That is, in a state where both side edges of the printed material are held by the receiving portions of the plurality of coil spring-shaped conveying members and spiral bodies, the printed matter is moved in the vertical direction by rotating the conveying members and spiral members.Printed paper discharge storage deviceIn this case, the distance between the conveyance bodies on both sides that hold the edges on both sides of the printed matter and between the spirals is extremely important. If the distance adjustment is inappropriate and too wide, the printed matter conveyed to the vertical transfer position will be conveyed. Each drive system is stopped because it is not transferred in the vertical direction by the body or the spiral. However, at this time, the operator can immediately determine whether the cause of the conveyance failure is due to the jam of the printed matter or the setting position failure due to the misadjustment of the distance between the conveyance bodies or between the spiral bodies. There wasn't.
[0008]
  For example, when using paper that is considerably wider than the postcard size and then printing using postcard size paper, the distance between the transport and the spirals should be reduced according to the width of the paper used. Is forgotten, the printed material is not conveyed upward by the conveying body or the spiral body although the respective conveying body and the helical body are normally rotated.
[0009]
  Even in such a case, since the operator does not know the cause of the conveyance failure from the outside of the device, if the cause is thought to be the cause of the jam, it will try to handle the jam, so the true cause However, there is a problem in that it is delayed to notice the distance adjustment failure (setting position failure) of the transport body and the spiral body, which may waste time.
The present invention has been made in view of the above problems. When a conveyance failure occurs, it is immediately determined whether the cause is a jam of a printed matter or a setting position of a conveyance member or a spiral member. The purpose is to be able to judge.
[0011]
[Means for Solving the Problems]
  In order to achieve the above-mentioned object, the present invention is provided so as to be able to approach and separate from each other so that both side edges of the printed material conveyed to the vertical transfer position can be held by a plurality of receiving portions provided at predetermined intervals in the vertical direction. A plurality of spiral bodies and a transport device that transports the printed matter held by the receiving section to a storage section provided at an upper portion of the apparatus body by rotating each of the spiral bodies, and is transported toward the vertical transport position. A first sensor and a second sensor for detecting a printed matterPrinted paper discharge storage deviceIs configured as follows.
[0012]
  That is, the second sensor is disposed at a position where the printed material conveyed to the vertical transfer position can be detected, and the first sensor is spaced from the second sensor upstream in the conveyance direction of the printed material. If the second sensor does not detect the printed matter within a predetermined time after the first sensor detects the printed matter, the jam is detected and the second sensor detects the printed matter. In addition, when the second sensor continues to detect the printed matter even after a predetermined elapsed time from the start of rotation of each spiral body, a conveyance failure determination means for determining a setting position failure of the spiral body is provided,Printed paper discharge storage deviceConfigure.
[0013]
  In this way, when the printed matter is jammed after being detected by the first sensor, the printed matter is not detected by the second sensor within a predetermined time after being detected by the first sensor. It is determined that a jam has occurred. In addition, when the distance between the spirals is too large with respect to the width of the printed matter to be used, even if the printed matter is conveyed to the vertical transfer position and detected by the second sensor, and each spiral starts to rotate, Since the distance adjustment between the spirals is inappropriate, the printed matter is not transported upward by the spirals. Therefore, the second sensor continues to detect the printed matter even when a predetermined elapsed time has elapsed since each helical body started to rotate, so that a defective setting position of the helical body is determined.
[0014]
  In addition, the abovePrinted paper discharge storage deviceIn this case, a display unit for displaying various warnings and the like is provided in a portion that can be seen from the outside of the apparatus, and when the conveyance failure determination unit determines a jam of the printed matter, the display unit displays a notification for the jam, When it is determined that the setting position is defective, the display unit may be provided with means for displaying a notification of the setting position defect of the spiral body.
[0015]
  By doing so, when a jam of the printed matter is determined, a display for notifying the jam is displayed on the display unit, and when a defective setting position of the spiral is determined, a display for notifying the display unit of the defective setting position of the spiral is displayed. Therefore, when a conveyance failure occurs, the operator can know at a glance from the outside whether the cause is a jam or a setting position failure of the spiral.
[0016]
  In addition, a display for notifying the jam is a warning display for turning on a warning light provided on the display unit, and a display for notifying the setting position failure of the spiral is a warning display for blinking the warning light, or It is recommended that the warning display be turned on and off. By doing so, the warning lamp on the display unit can be used both as a display for notifying a jam and a display for notifying the setting position failure of the spiral body, so that the display unit can be made compact. In the case of a warning display that blinks a warning light, the warning effect is further enhanced because it is more noticeable than when the warning light is simply turned on.
[0017]
  Furthermore, it comprises a plurality of conveyance bodies provided so as to be able to approach and separate from each other so that both side edges of the printed material conveyed to the vertical transfer position can be held by a plurality of receiving portions provided at predetermined intervals in the vertical direction, A transporting device for transporting the printed matter held by the receiving unit to a storage unit provided at the upper part of the apparatus main body by rotating each of the transport bodies so that the receiving unit moves in the vertical direction, and a vertical transporting position. Provided with a first sensor and a second sensor for detecting printed matter conveyed towardPrinted paper discharge storage deviceMay be configured as follows.
[0018]
  That is, the second sensor is disposed at a position where the printed material conveyed to the vertical transfer position can be detected, and the first sensor is spaced upstream of the second sensor in the conveying direction of the printed material. When the second sensor does not detect the printed matter within a predetermined time after the first sensor detects the printed matter, the jam of the printed matter is judged, and the second sensor detects the printed matter and Provided with a conveyance failure judgment means for judging the set position failure of the conveyance body when the second sensor continues to detect the printed matter even after a predetermined elapsed time has elapsed since the conveyance body started to rotate. ,Printed paper discharge storage deviceIt is good to configure.
[0019]
  Even if it does in this way, when the printed matter is jammed after being detected by the first sensor, the printed matter is not detected by the second sensor within a predetermined time after being detected by the first sensor. It is determined that a jam has occurred. In addition, when the distance between the transport bodies is too large with respect to the width of the printed material to be used, the printed materials are transported to the vertical transfer position, which is detected by the second sensor, and each transport body starts to rotate. However, since the distance adjustment between the conveyance bodies is inappropriate, the printed matter is not transferred upward by the conveyance body. Accordingly, the second sensor continues to detect the printed matter even after a predetermined elapsed time has elapsed since each conveyance body started to rotate, and therefore, a defective setting position of the conveyance body is determined.

To be able to.
[0026]
  In the main body frame 40 shown in FIG. 4, the spiral units 50 and 60 constituting the transfer device as shown in FIG. 5R> 5 are shown in FIG. As shown in FIG. 2, the sheet is opposed to each other across a sheet conveyance path at the center of the apparatus. As shown in FIG. 5, the spiral units 50 and 60 are formed symmetrically with respect to the sheet conveyance path, and the spiral unit 50 includes a unit support 53 formed in a U-shaped cross section. The connecting plate 55 is fixed to the upper end of the 54 and the U-shaped connecting plate 56 having a U-shaped cross section is fixed to the lower end by screwing or the like, and the U-shaped connecting plate 56 is arranged so that the U-shaped open side faces inward. ing.
[0027]

Similarly, the helical unit 60 also has a connecting plate 64 fixed to the upper ends of unit pillars 58 and 59 each having a U-shaped cross section, and a U-shaped connecting plate 62 having a U-shaped cross section fixed to the lower end by screwing or the like. The U-shaped connecting plate 62 is arranged so that the U-shaped open side faces inward. Then, between the connecting plate 64 and the U-shaped connecting plate 62, the spiral bodies 26A and 26B are arranged at intervals in the printing paper conveyance direction, and the upper and lower shaft portions 26a are respectively connected via bearings 57. It is supported rotatably.
[0028]
  The spiral bodies 25A and 25B and 26A and 26B have the same shape. The spiral bodies 25A and 25B are shown in FIG. 8A, and the spiral bodies 26A and 26B are shown in FIG. 8B (FIG. 8). As shown in (a) and (b), the shaft portions 25a and 26a are both omitted), the longitudinal direction (axial direction) is formed on the outer peripheral surface of the member formed in a cylindrical or columnar shape. The belt-shaped receiving portions 25b and 26b formed in a spiral shape with a predetermined interval along the projecting body are projected and formed by integral molding with resin. And the protrusion amount H of the strip | belt-shaped receiving parts 25b and 26b projected in the spiral form on the outer peripheral surface is set to 4.5 mm, for example.
[0029]
  The spiral bodies 25A, 25B and 26A, 26B differ only in that the spiraling directions of the receiving portions 25b and 26b are reversed, and the spiral body 25A faces the spiral body 26A as shown in FIG. The spiral body 25B faces the spiral body 26B. The spiral winding direction of the receiving portions 25b and 26b of each of the spiral bodies 25A, 25B, 26A and 26B is such that the printing paper P inserted between the receiving portions 25b and 26b adjacent to each other above and below is inserted into the spiral bodies 25A, 25B and 26A. And 26B are formed in directions in which force is applied in the direction of pressing against the rear lower cover 52 shown in FIG.

The lower driving force transmission gear 84 meshes with the sector gear 73 of the lower approach / separation mechanism 72.
[0045]
  As described with reference to FIG. 5, the spiral bodies 25 </ b> A and 25 </ b> B are integrally formed by the connecting plate 55 and the U-shaped connecting plate 56, and the spiral bodies 26 </ b> A and 26 </ b> B are also connected to the connecting plate 64 and the U-shaped connecting plate 62. Therefore, when the knob 83 in FIG. 10 is rotated in the clockwise direction in FIG. 10, the sector gear 73 is rotated in the counterclockwise direction, and the sector gear is rotated along with the rotation. The sector gear 77 rotates in the clockwise direction by the same amount as the rotation amount of the sector gear 73 via the interlocking gears 81 a and 81 b meshing with the 73.

Therefore, the double pulley 66 is rotated by the timing belt 63 rotating in the same direction, and the spiral body 25B is rotated counterclockwise.
[0055]
  Thus, when the spiral bodies 25B and 26B rotate in directions opposite to each other, the spiral bodies 25A and 25B are interlocked by the timing belt 61 as described in FIG. 6, and the spiral bodies 26A and 26B are also connected to the timing belt. Accordingly, the four spiral bodies 25A, 25B and 26A, 26B are all rotated by one pulse motor 29 in the directions indicated by arrows in FIG.
[0056]
  Further, even if the helical body rotating device 90 shown in FIG. 13 moves the helical bodies 25B and 26B toward and away from each other by rotating about the supporting shafts 75 'and 79', respectively, the second intermediate gear 35 and the pulley gear 38 are provided. Since the distance between the rotation centers and the distance between the rotation centers of the first intermediate gear 34 and the pulley gear 37 are both constant, the spiral bodies 25B and 26B and 25A and 26A always rotate smoothly at any position. thisPrinted paper discharge storage deviceAs shown in FIGS. 9 and 11, the belt transport device 95 is disposed at the entrance portion for receiving the printing paper P on the bottom plate 45.
[0057]
  The belt conveying device 95 is a conveying device that conveys the printing paper P to the vertical transfer position shown in FIG.

As shown in FIG. 9, the intermediate guide plate 24 is fixed to the inner surface of the unit support 59 of the spiral unit 60 with screws.
[0062]
  On the other hand, above the spiral bodies 25A, 25B and 26A, 26B, a storage section 5 for storing the printing paper P raised by the spiral bodies is provided. The storage portion 5 is a space portion formed at the upper part of each of the spiral unit 50 and 60 described with reference to FIG. 5, and on the inner surface of the upper portion of the unit support 58, 59 of the spiral unit 60, as shown in FIG. A storage guide plate (not shown) corresponding to the storage guide plate 6 is similarly attached to the upper inner surfaces of the unit columns 53 and 54 on the spiral unit 50 side of FIG. Is fixed with screws.
[0063]
  Also thisPrinted paper discharge storage deviceAs shown in FIG. 10, the upper ends of the shaft portions 25a and 26a of the spiral bodies 25A, 25B, 26A and 26B are protruded from the top surface side of the top plate 46, respectively. Then, as shown in FIG. 15, on the upper surface of the upper exterior cover 49 that covers the top plate 46 on the upper ends of the shafts 25 a of the spiral bodies 25 </ b> A and 25 </ b> B that hold one side edge Pa of the printing paper P, One of the printing paper Ps (the same size as the printing paper P and before printing) set at a predetermined setting position by abutting the leading end against an abutting portion 51a formed with a predetermined width on the rear upper cover 51 One side edge guide 101 to be brought into contact with the side edge Psa is attached.
[0064]
  Further, the printing paper Ps set at the predetermined set position on the upper surface of the upper exterior cover 49 is formed at the upper end of each shaft portion 26a of the spiral body 26A, 26B on the side holding the other side edge Pb of the printing paper P. The other side edge guide 102 to be brought into contact with the other side edge Psb is attached.
[0065]
  Note that the print paper Ps set on the upper surface of the upper exterior cover 49 is set at a position where the leading end of the print paper Ps is pushed by the rear upper cover 51 as described above when the print paper Ps is a small size. The position where it abuts against the abutting portion 51a is the set position, and as shown in FIG. 2, the distance between the inner sides of the abutting projections 49c, 49c provided near the rear upper cover 51 on the upper surface of the upper exterior cover 49 is larger than the distance WL. When printing paper having a large paper width is used, the position where the leading edge of the printing paper abuts against the abutting protrusions 49c, 49c is the setting position, but the portion related to the setting position of the printing paper is not directly related to the present invention. Detailed description thereof will be omitted.
[0066]
  The side edge guides 101 and 102 are paired with the side edge guide 101 in conjunction with the left side spiral bodies 25A and 25B in FIG. 15, and the side edge guide 102 is linked with the right side spiral bodies 26A and 26B. To do. Then, the mounting positions of the pair of side edge guides 101 and 102 to the respective shaft portions 25a and 26a of the respective spiral bodies 25A, 25B, 26A and 26B are determined. When the spirals 25A, 25B, 26A and 26B are brought into contact with the side edges Psa and Psb of the printing paper Ps set at the set position (the position shown in FIG. 15), the receiving portions 25b, A position 26b holds the side edges Pa and Pb of the printing paper P transferred to the storage unit 5 (see FIG. 9).
[0067]
  That is, when the side edge guides 101 and 102 are brought into contact with the both side edges Psa and Psb of the printing paper Ps as described above, the spiral bodies 25A, 26A and 25B shown in FIGS. 26B, the distance W between the valley bottoms is set to a distance obtained by adding α to the width Pw between the side edges Pa and Pb of the printing paper P.
[0068]
  Specifically, as shown in FIG. 15, when the side edge guides 101 and 102 are brought into contact with both side edges Psa and Psb of the printing paper Ps, the side edges of the printing paper P transferred to the storage unit 5. Pa is held in a state of about 2/3 (about 3 mm) on each receiving portion 25b of the spiral bodies 25A and 25B, and the side edge Pb side is similarly about 2/3 on each receiving portion 26b of the spiral bodies 26A and 26B. Make sure it is held on the surface.
[0069]
  When the side edge guides 101 and 102 are brought into contact with or separated from the both side edges Psa and Psb of the printing paper Ps, the spiral bodies 25A, 25B, 26A and 26B are rotated by rotating the knob 83 described in FIG. , Thereby interlocking the side edge guides 101 and 102.
[0070]
  As shown in FIG. 2, the side edge guides 101 and 102 are guide grooves 111, 112, 113 formed on the upper surface of the upper exterior cover 49 in an arc shape along the moving direction of the spiral bodies 25A, 25B, 26A, and 26B. 16 and 114, projections 101c, 101d and 102c, 102d respectively projecting from the lower surfaces of both end portions in the longitudinal direction are movably fitted, as shown in FIG.
[0071]
  Each of the convex portions 101c, 101d and 102c, 102d is formed with an E-ring groove, and by fitting the E-ring 115 there, the side edge guides 101, 102 are respectively attached to the upper exterior cover 49. The guide grooves 111 to 114 are prevented from falling off. In addition, shaft insertion holes 116 for inserting the shaft portions 25a and 26a of the respective spiral bodies are respectively formed on the lower surfaces of the respective convex portions 101c, 101d, 102c and 102d, and the respective spiral bodies 25A, 25B, 26A and The shaft portions 25a and 26a of 26B are respectively fitted.
[0072]
  Further, as shown in FIG. 15, the side edge guides 101 and 102 are provided with lower surfaces 101 a and 102 a of the side edge guides 101 and 102 of the printing paper Ps set at a predetermined setting position on the upper exterior cover 49. Protrusions 103 and 104 that prevent entry into the lower side are extended along the surfaces 101b and 102b that contact the side edges Psa and Psb of the printing paper Ps.
[0073]
  Then, the protrusions 103 and 104 are formed in the recesses 106 and 107 formed in an arc shape along the moving direction of the side edge guides 101 and 102 on the upper surface of the upper exterior cover 49 as shown in FIG. It is inserted so that it can move along the moving direction of 102. The recesses 106 and 107 may be arcuate long holes.
[0074]
  In this way, the side edge guide 101 is provided with the projection 103 as shown in FIG. 15 and the side edge guide 102 is provided with the projection 104, so that the side edge guides 101 and 102 are arranged at the upper portion as shown in FIG. When the two side edges Psa and Psb of the printing paper Ps set at a predetermined set position on the exterior cover 49 abut each other, the both side edges Psa and Psb enter below the side edge guides 101 and 102. Each protrusion 103, 104 can prevent this.
[0075]
  Accordingly, it is possible to prevent the distance between the side edge guides 101 and 102 from becoming narrower than the width of the printing paper Ps. Therefore, the distance between the spiral bodies 25A and 26A and the distance between the spiral bodies 25B and 26B are set respectively. It can be accurately set at an ideal position corresponding to the printing paper P. In addition, thisPrinted paper discharge storage device4, as shown in FIG. 4, a long hole 46 e is formed in the top plate 46 along the conveyance direction of the printing paper, and a rear end fence 7 as shown in FIG. 9 is provided so as to be slidable in the arrow G direction. ing.
[0076]
  Further, as shown in FIG. 2, a stencil printing apparatus is provided with a rear end guide 105 which is brought into contact with the rear end edge of the printing paper Ps set on the upper surface of the upper exterior cover 49 at the predetermined setting position described above. 9 is provided so as to be movable along the discharge direction (arrow J direction) of the print paper P discharged from one paper discharge portion 3, and stored in the storage portion 5 described in FIG. A rear end fence 7 that abuts the rear end (right end side in FIG. 9) and regulates the position of the printing paper P is fixed.
[0077]
  thisPrinted paper discharge storage device2, the trailing edge guide 105 is slid in the arrow G direction in accordance with the size of the printing paper P to be used, and the printing paper Ps set at a predetermined setting position on the upper exterior cover 49 If the trailing edge is brought into contact with the trailing edge, the trailing edge fence 7 comes into contact with the trailing edge of the printing paper P stored in the storage unit 5 to be a position for regulating the printing paper P.
[0078]
  Therefore, since the rear end fence 7 can prevent the stacking deviation of the printing paper P stacked in the storage portion 5 in the stacked state, the ink surface of the printing paper P generally in a state where the ink is dried to some extent is misaligned. When it is rubbed, the back side of the printing paper tends to be stained, but it can be prevented.
[0079]
  FIG. 17 is a plan view showing the operation unit 8 described in FIG. The operation unit 8 also serves as a display unit for displaying various warnings and the like. The operation unit 8 receives the spiral bodies 25A, 25B, 26A and 26B each time the printing paper P is received in the receiving units 25b and 26b. The interval stack key 141, the reset key 142, and the receiving portions 25b and 26b of the spiral bodies 25A, 25B, 26A, and 26B that are operated when changing the predetermined amount of rotation from one rotation to two rotations. A paper up key 143 and a start / stop key 144 that are pressed when all the printing paper P is transferred to the upper storage unit 5 are provided.
[0080]
  In addition, the operation unit 8 includes a jam display unit 171 that also serves as a display unit for notifying a printing paper jam and a spiral setting position failure, and a cover open that notifies the release when the rear lower cover 52 is opened. A display unit 172, a full display unit 173 that informs the storage unit 5 that the printing paper is full, and an interval stack display unit that informs that the interval stack mode is selected when the interval stack key 141 is pressed. 174 is also provided.
[0081]
  Lamps as warning lights (not shown) are respectively arranged below the display units. When the lamps are turned on, the display units are lit in red, for example. In this embodiment, the jam display unit 171 lights up the lamp continuously when the printing paper is jammed, and there is a setting position defect in the distance between the spirals, and the printing paper is in the vertical transfer position described above. A warning is displayed in which the lamp blinks when there is a conveyance failure that does not rise. The warning display may be such that the lamp blinks when the printing paper is jammed, and that the lamp is continuously lit when the setting position of the spiral is defective.
[0082]
  thisPrinted paper discharge storage device2 is used by being mounted on a stencil printing apparatus 1 as shown in FIG. 3, for example, first, it is set at a predetermined position on a discharge tray 17 of the stencil printing apparatus 1 as shown. And although illustration is omitted,Printed paper discharge storage device2 is connected to a plug (not shown) provided on the stencil printing apparatus 1 side correspondingly.
[0083]
  Next, in order to reliably hold the side edges Pa and Pb of the printing paper P between the spiral bodies 25A and 26A and 25B and 26B shown in FIG. 11, the knob 83 shown in FIG. As shown in FIG. 15, the pair of side edge guides 101 and 102 are in contact with both side edges Psa and Psb of the printing paper Ps (same size as the printing paper P) set at a predetermined setting position on the upper exterior cover 49. Move to position.
[0084]
  By doing so, the spiral bodies 25A, 25B, 26A and 26B interlocked with the side edge guides 101 and 102 also move, so that printing between the spiral bodies 25A and 26A and between 25B and 26B is transferred to the storage unit 5. The distances Pa and Pb on both sides of the paper P are optimum distances suitable for the transfer of the printing paper P holding about 2/3 (about 3 mm) of the receiving portions 25b and 26b of the spiral bodies 25A, 25B and 26A and 26B, respectively. .
[0085]
  Further, according to the size of the printing paper P to be used, the position of the rear end fence 7 shown in FIG. 9 is set to a predetermined set on the upper exterior cover 49 shown in FIG. 15 by sliding the rear end guide 105. Adjustment is made so that the trailing edge of the printing paper Ps set at the position is brought into contact with the printing paper P stored in the storage unit 5 so as not to be misaligned.
[0086]
  In this state, as shown in FIG.Printed paper discharge storage device2 is turned on and the start / stop key 144 is pressed to turn it on. Here, when a document to be printed is set on the document reading device of the stencil printing apparatus 1 shown in FIG. 3 and the printing paper P to be printed is a postcard, the number of sheets to be printed on the paper feed tray 12 is set. Place a postcard and several sheets of paper of the same size on the postcard.
[0087]
  After that, when a plate making start key is pressed on the operation panel 4 of the stencil printing apparatus 1, reading of the original is started after the used stencil master is peeled off from the surface of the printing drum 11 and discarded by a plate discharging apparatus (not shown). At the same time, the stencil master is punched by a thermal head, and the stencil master after the stencil is wound around the outer peripheral surface of the printing drum 11.
[0088]
  Next, plate printing is performed on a sheet for printing (the same size as the postcard), and a first printed material (hereinafter referred to as a printed material) is transferred by the paper discharge conveyor belt 16.Printed paper discharge storage device2 is sent. The plate printing performed here is printing performed to familiarize the stencil master because the ink is not yet sufficiently familiar to the stencil master.
[0089]
  In the same manner as the position indicated by the printing paper P in FIG. 11, the printed material with plate is conveyed by the belt conveying device 95 to the illustrated vertical transfer position where the leading end abuts against the inner surface of the rear lower cover 52. Is held in a state of being received by the receiving portions 25b and 26b of the spiral bodies 25A, 25B, 26A and 26B. When the first sensor 19 detects the passage of the printed material with the plate and the second sensor 18 detects that the printed material with the plate has reached, the pulse motor 29 described with reference to FIG. 13 is driven, and the spiral bodies 25A, 25B. , 26A and 26B are rotated once, and the printed material with plate is conveyed upward by a distance corresponding to one stage of each receiving portion 25b, 26b.
[0090]
  At that time, the rotational directions of the rotating spiral bodies 25A, 25B, 26A and 26B are respectively opposite to each other as indicated by arrows in FIG. 11 as opposed to the spiral bodies 25A and 26A and 25B and 26B, respectively. The Therefore, the printed matter with a plate ascends along the rear lower cover 52 while the front end is pressed against the inner surface of the rear lower cover 52.
[0091]
  Next, the operator first opens the rear upper cover 51 in the direction indicated by the arrow B in FIG. 2, and then opens the rear lower cover 52 in the direction indicated by the arrow C (see also FIG. 9). Check the image and print position. If necessary, when the operation of correcting the density of the ink or the deviation of the printing portion with respect to the printing paper is performed, or when printing is performed again after a period of printing, the stencil printing apparatus 1 is used. Since it is necessary to see what version is installed, test printing is performed.
[0092]
  Here, if there is no problem with the printing and test prints, the printing and trial printing paper placed on the top of the printing paper P set on the paper feed tray 12 in FIG. The printing start key on the operation panel 4 is pressed to start printing on the printing paper P as a postcard. Then, the printing paper P on the paper feed tray 12 is continuously conveyed to the printing drum 11 and an image is printed there.
[0093]
  The printing paper P is fed between the spirals 25A and 26A and 25B and 26B shown in FIG. 11, and the leading end of the printing paper P abuts against the rear lower cover 52, as in the case of the printed matter with plate described above. To the vertical transfer position, and the side edges Pa and Pb are held in a state of being received by the receiving portions 25b and 26b, respectively.
[0094]
  Then, when the printing paper P passes through the belt conveying device 95, the first sensor 19 detects the printing paper P, and when the second sensor 18 detects the printing paper P, the pulse motor 29 described in FIG. Driven to rotate the spiral bodies 25A, 25B, 26A, and 26B once in the normal mode, and sequentially convey the printing paper P upward by a distance corresponding to one stage of each receiving portion 25b and 26b.
[0095]
  Such operations are sequentially repeated, and when printing on the set number of print sheets P is completed, as shown in FIG. 14, the uppermost receiving portions of the spiral bodies 25A, 25B, 26A, and 26B, respectively. The printing paper P that has passed 25b and 26b is stacked on the last receiving portions 25b 'and 26b' of the final portion to be sent to the storage portion 5 provided thereabove. As shown in FIG. 1, it is held in the receiving portions 25b and 26b of the respective stages of the spiral bodies 25A, 25B, 26A and 26B with a space in the vertical direction.
[0096]
  Here, when the printing is finished, the paper up key 143 provided in the operation unit 8 (FIG. 17) is pressed. Then, the pulse motor 29 shown in FIG. 1 rotates continuously by rotating the respective spiral bodies 25A, 25B, 26A and 26B a predetermined number of times. Therefore, all the printing papers P that are being stored and transferred to the storage unit 5 and held by the receiving units 25b and 26b of the respective stages of the spiral bodies 25A, 25B, 26A, and 26B are raised to the storage unit 5, Stacked there.
[0097]
  Therefore, if the rear upper cover 51 shown in FIG. 14 is opened in the direction indicated by the arrow B, U-shaped grooves 49a and 9 are formed in the upper exterior cover 49 shown in FIG. 2 and the top plate 46 shown in FIG. Therefore, it is possible to draw out a bundle of printing paper P stacked in the storage unit 5 by putting a finger in the storage unit 5 so as to be picked up in the vertical direction, and to easily take it out.
[0098]
  As described with reference to FIGS. 8A and 8B, the pitch P3 of the final portion for sending the printing paper P of the receiving portions 25b and 26b of the spiral bodies 25A, 26A, 25B and 26B to the storage portion 5 is as follows. Since it is larger than the pitch P1 of the intermediate part of each spiral body, as shown in FIG. 14, the printing paper P stacked in the storage part 5 and the respective receiving parts 25b, 26b of the spiral body adjacent in the vertical direction thereof. Since the space between the printing paper P and the printing paper P that is still being transferred is widened, the printing paper P stacked in the storage unit 5 is gathered together with a finger placed under the printing paper P and held. It can be taken out.
[0099]
  Further, when the sheet raising key 143 in FIG. 1 is pressed, the predetermined number of times that the spiral bodies 25A, 25B, 26A, and 26B are continuously rotated by rotating the pulse motor 29 is, for example, the receiving portion of each spiral body. The number of times (for example, 65 rotations) until the printing paper Pe held last in 25b and 26b is transferred to the storage unit 5 and stored. For example, an encoder (not shown) mounted on any one of the four spiral bodies 25a or 26a is used to detect the rotational speed of each of the spiral bodies 25A, 25B, 26A and 26B. .
[0100]
  By the way, thisPrinted paper discharge storage device2, when the second sensor 18 does not detect the print paper within a predetermined time T after the first sensor 19 detects the print paper, the jam of the print paper is determined. When the second sensor 18 continues to detect the printing paper even if a predetermined elapsed time t has elapsed since the detection of the printing paper and the spiral bodies 25A and 26A and 25B and 26B started to rotate, the helical body 25A. 26A and the control device 10 functioning as a conveyance failure judgment means for judging the setting position failure of the spiral bodies 25B and 26B.
[0101]
  When the control device 10 determines a jam of the printed matter, the control device 10 displays on the jam display unit 171 to notify the jam. When the control device 10 determines that the setting position of the spiral is defective, the control unit 10 displays the setting position failure of the spiral on the jam display unit 171. It also functions as a means for displaying for notification.
[0102]
  The control device 10 includes a microcomputer 30. The microcomputer 30 has a central processing unit (CPU) having various determination and processing functions, a ROM storing each processing program and fixed data, and processing data. It consists of a RAM, which is a data memory to be stored, and an input / output circuit (I / O), and also has a timer 120.
[0103]
  The control device 10 inputs an on / off signal from the interval stack key 141, the reset key 142, the paper up key 143, and the start / stop key 144 of the operation unit 8 when they are pressed. Further, when a full detection signal is detected from the full detection sensor 126 that detects the fullness of the print paper P provided in the storage unit 5 and the print paper P is detected from the first sensor 19 and the second sensor 18, respectively. Input the detection signal to be output. Further, the cover open detection sensor 125 inputs a cover open signal that is output when the rear lower cover 52 is opened.
[0104]
  The control device 10 outputs a drive signal for rotating the pulse motor 29 and the belt driving motor 91 of the belt conveying device 95 at a predetermined timing, and a jam display portion 171, a cover open display portion 172, Various display signals are output to various display units of the full display unit 173 and the interval stack display unit 174, and each warning lamp provided therein is turned on at a predetermined timing.
[0105]
  FIG. 18 is a flowchart showing a conveyance failure processing routine performed by the microcomputer 30 of the control device 10. When the routine of FIG. 18 starts, the microcomputer 30 first resets the timer 120 included in the microcomputer 30 in step 1.
[0106]
  Next, in step 2, it is determined whether or not the first sensor 19 has detected the printing paper and turned on. If it has not been turned on, the printing paper has been conveyed to the position of the first sensor 19. Since it does not exist, it waits as it is, and when it becomes ON, it progresses to step 3, the timer 120 is started, and time measurement is started.
[0107]
  In the next step 4, it is determined whether or not the second sensor 18 has detected the printing paper and turned on. That is, whether or not the transported printing paper has reached the vertical transfer position indicated by the printing paper Pe in FIG. 1 is determined based on whether or not the second sensor 18 is turned on.
[0108]
  If it is not ON, it is determined in step 5 whether or not 1.5 seconds (predetermined time T) have passed since the first sensor 19 was turned ON. If not, the process returns to step 4 to determine whether or not the second sensor 18 is turned on again. Then, when the second sensor 18 is turned on, the process proceeds to Step 6 to rotate the pulse motor 29 to rotate each of the spiral bodies 25A, 26A, 25B, and 26B once.
[0109]
  In the next step 7, it is determined whether or not the second sensor 18 is ON for 0.7 seconds (predetermined elapsed time t). The printing paper Pe transported to the vertical transfer position shown in FIG. 1 by one rotation of the spiral is raised by a height corresponding to one stage of the receiving portions 25b and 26b of the spirals 25A, 26A, 25B and 26B. As a result, it has been raised to the position of the printing paper Pe ′, and since normal transfer has been performed, the routine returns to the main routine.
[0110]
  If the second sensor 18 is ON for 0.7 seconds or more and the process proceeds to step 8 in step 7, the pulse motor 29 and the belt drive motor 91 are stopped in step 8. ,thisPrinted paper discharge storage deviceThe driving of the transport system 2 is stopped.
[0111]
  At this time, a signal for stopping the printing operation may be sent to a control device (not shown) on the main body side of the stencil printing apparatus 1, and the printing operation of the stencil printing apparatus 1 may be stopped based on this signal. Then, in the next step 9, the lamp of the jam display section 171 is blinked to issue a warning notifying the defective setting position of the spiral body, and then the process returns to the main routine.
[0112]
  On the other hand, if the second sensor 18 is not ON in the determination of step 4, the process proceeds to step 5, and even if 1.5 seconds have elapsed after the first sensor 19 is turned ON, the second sensor 18 Is not turned ON, the printing paper has not been conveyed to the vertical transfer position due to some conveyance trouble, so the process proceeds to step 10 to stop the pulse motor 29 and the belt drive motor 91, therebyPrinted paper discharge storage deviceThe driving of the transport system 2 is stopped.
[0113]
  At this time, a signal for stopping the printing operation may be sent to a control device (not shown) on the main body side of the stencil printing apparatus 1, and the printing operation of the stencil printing apparatus 1 may be stopped based on this signal. In the next step 11, the lamp of the jam display unit 171 is turned on to issue a warning notifying that a jam has occurred, and then the process returns to the main routine.
[0114]
  Like thisPrinted paper discharge storage device2, when a jam occurs after the printing paper is detected by the first sensor 19, the printing paper is a predetermined time T after the detection by the first sensor 19 (in this embodiment, 1. Since the second sensor 18 does not detect within 5 seconds), it is determined that a jam has occurred, and the lamp of the jam display portion 171 is turned on to display a warning.
[0115]
  When the distance between the spirals 25A and 26A and 25B and 26B is too large with respect to the width of the printing paper to be used, the printing paper is conveyed to the vertical transfer position (position where the printing paper Pe in FIG. 1 is present). Even if each of the spiral bodies makes one rotation by being detected by the second sensor 18, the distance between the spiral bodies 25A and 26A and 25B and 26B is not suitable, so the printing paper is transported upward. Not.
[0116]
  Therefore, even if a predetermined elapsed time t (0.7 seconds in this embodiment) elapses after each spiral body 25A, 26A, 25B and 26B starts rotating, the second sensor 18 detects the printing paper. Therefore, the setting position of the spiral is determined to be poor, and the lamp of the jam display unit 171 blinks to display a warning.
[0117]
  Therefore, when the printing paper becomes jammed, a display for informing the jam display unit 171 is made by lighting the lamp, and when it is judged that the setting position of the spiral is poor, a warning display different from that at the time of jamming is displayed on the jam display unit 171. Since the lamp blinks, the operator can know at a glance from the outside whether the cause of the conveyance failure is a jam or the setting position of the spiral body is defective.
[0118]
  If there is a means to determine whether the printing paper conveyance failure is caused by printing paper jam or the spiral setting position failure, a warning is issued in response to the conveyance failure cause. This method is not limited to the lighting and blinking of the lamp provided in the jam display unit 171 according to the above-described embodiment, but may be a warning message recorded on a buzzer or a recording tape.
[0119]
  In addition, as the spiral body, if the receiving portion is formed on the outer peripheral surface in a spiral shape with a predetermined interval in the axial direction of the spiral body, the receiving portion protrudes in a belt shape as described in FIG. You don't have to be limited to that. For example, the receiving portion may be spirally formed by a coil spring, or a spiral holding groove is formed on the outer peripheral surface of a cylindrical or columnar rotating member at a predetermined interval in the axial direction thereof. Depending on the situation, a receiving portion may be provided.
[0120]
  Further, in the above-described embodiment, the belt conveyance device 95 that conveys the printed matter to the vertical conveyance position is provided in addition to the conveyance device constituted by the helical units 50 and 60 and the helical rotation device 90.Printed paper discharge storage device2 has been described, the present invention can also be applied to a configuration in which such a belt conveying device 95 is not provided.
[0121]
  For example, the printed matter is directly discharged from the paper discharge portion of the printing apparatus to the inlet portions of the spiral units 50 and 60 constituting the transfer device, the first sensor 19 is provided at the inlet portion, and the first sensor The spiral unit 50 and 60 is operated at a predetermined timing in response to a signal detected by the printed matter 19, and the printed material conveyed to the vertical transfer position is transferred to the storage unit 5 while being held by the receiving portions 25b and 26b of each helical body. You may make it do. Further, a conveying device such as a belt conveying device 95 (a roller conveying method or the like is not limited to belt driving), and the stencil printing apparatus 1Printed paper discharge storage deviceYou may make it arrange | position separately between.
[0122]
  In FIG. 19, an endless belt is used as a transport body for transferring printing paper held in the receiving section to the storage section.Printed paper discharge storage deviceIt is a perspective view which shows only this embodiment only the belt vicinity. thisPrinted paper discharge storage deviceRespectively, endless belts 325A, 325B, 325C, and 325D, which are transport bodies, are disposed on both side edges Pa of printing paper P discharged from a paper discharge portion of a printing apparatus such as the stencil printing apparatus 1 described in FIG. Pb is disposed at a position that can be held by a plurality of receiving portions 325b provided over the entire circumference at predetermined intervals in the vertical direction.
[0123]
  The belts 325A and 325B and 325C and 325D are supported by the side plates 401 and 402 on both sides so as to be movable toward and away from each other via the support shafts 326, 327, 328, and 329 (the support portion is the same). Simplified illustration). Then, the endless belts 325A, 325B, 325C, and 325D are rotated in conjunction with the respective arrow directions shown in FIG. 19 by simultaneously rotating the support shafts 326, 327, 328, and 329 by a motor (not shown). Each receiving part 325b moves up and down.
[0124]
  Each of the endless belts 325A, 325B, 325C, and 325D has a predetermined amount, for example, one receiving portion 325b, in the direction of the arrow each time the printing paper P is received by each receiving portion 325b at the printing paper receiving position provided at the lower portion thereof. The printing paper P is rotated by an amount that moves up and down by steps, and the printing paper P is transferred to the storage portion 5 '(only the position is shown), and stored in a stacked state there.
[0125]
  In this way, a belt was used for the carrier.Printed paper discharge storage deviceAlso used the aforementioned spiral bodyPrinted paper discharge storage device2, as described in FIG. 1, the second sensor 18 is arranged at a position where the printing paper Pe conveyed to the vertical transfer position can be detected, and the first sensor 19 is replaced with the second sensor 18. The second sensor 18 detects the printing paper P within a predetermined time after the first sensor 19 detects the printing paper P. If not, a jam of the printing paper P is judged, and the second sensor 18 detects the printing paper P, and a predetermined elapsed time has elapsed since the belts 325A, 325B, 325C and 325D started to rotate. However, when the second sensor 18 continues to detect the printing paper P, it is preferable to provide a conveyance failure judging means (corresponding to the control device 10 in FIG. 1) for judging the belt setting position failure.
[0126]
  In this way, when the print paper P is jammed after being detected by the first sensor 19, the print paper P is in the second time within a predetermined time after being detected by the first sensor 19. Since it is not detected by the sensor 18, it is determined that a jam has occurred.
[0127]
  If the distance between the belts 325A and 325B and the distance between 325C and 325D shown in FIG. 19 is too large for the width of the printing paper P to be used, the printing paper P is shown in FIG. Even if the belts 325A, 325B, 325C, and 325D start to rotate after being transported to a position corresponding to the vertical transfer position indicated by the position and detected by the second sensor 18, the distance between the belts Therefore, the printing paper Pe is not transported upward by the belts. Accordingly, the second sensor 18 continues to detect the printing paper Pe even after a predetermined elapsed time has elapsed since the belts 325A, 325B, 325C, and 325D started to rotate. A belt setting position failure is determined.
[0128]
