[0001]
BACKGROUND OF THE INVENTION
The present invention provides a relatively small size printed matter having a certain level of strength, such as cards, postcards, envelopes, etc., to be discharged after printing from the paper discharge portion of the printing apparatus, and a belt-like receiving portion on the outer peripheral surface in a spiral shape. The present invention relates to a small-size printed matter discharge storage device that rotates and transfers a formed spiral body to a storage unit.
[0002]
[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 the set-off, the printed matter discharged earlier is dried by feeding the printing drum of the printing apparatus every several times to several tens of times instead of printing every rotation. There is an intermittent paper feed type in which the next printing is performed later, but in such a printing apparatus, the printing drum is idled and printing is not performed until the ink is dried, so the printing time is long. There was a problem that it took.
[0004]
Therefore, in a device for storing printed matter, as described in, for example, Japanese Patent Laid-Open No. 8-25736, a belt-shaped receiving portion (sheet support surface) is spirally formed continuously on the outer peripheral surface of the base shaft in the longitudinal direction. A plurality of projecting spiral bodies (lead screws) are provided, and by rotating the spiral bodies while holding the both side edges of the sheet-like printed material with the receiving portions by the plurality of spiral bodies, the intervals are maintained without overlapping the printed materials. There is a transfer device that prevents the set-off by transferring the ink in an open state over time and drying the ink in the meantime and storing it in a storage portion.
[0005]
[Problems to be solved by the invention]
As described above, in the case of a spiral transfer device that transfers the printed matter to the storage unit by rotating each helical member with both side edges of the sheet-like printed matter placed on each receiving portion of the opposing spiral member. The distance between the spirals is extremely important.
That is, if the distance between the spirals facing each other is made too small with respect to the width of the printed material to be transferred, the printed material cannot be well received between the spirals, which causes a jam.
[0006]
On the other hand, if the distance between the spirals is set too large, both side edges of the printed product will be separated from the receiving portions of the opposing spirals when the printed product is received between the spirals. It becomes a conveyance defect.
Therefore, if the band-shaped receiving part formed spirally on the outer peripheral surface of each spiral body is made to increase the amount of protrusion from the base axis (the band width of the receiving part is widened), the distance adjustment between the spiral bodies facing each other is adjusted. Each spiral body can be set relatively easily at a position where a jam or a conveyance failure does not occur even if the accuracy is not so high.
[0007]
However, when the spiral body is formed by integrally molding the base shaft and the spiral receiving portion with resin in consideration of cost, the amount of protrusion of the receiving portion from the base shaft cannot be increased as in the case of cutting. Therefore, the protrusion amount is generally about 4 to 5 mm.
[0008]
Therefore, in the case of a helical transfer device that sends a printed material between a plurality of spiral bodies in which a spiral receiving portion is formed integrally with the base shaft by molding in this way, the distance adjustment between the spiral bodies is adjusted. This is extremely important, and if it is not performed with high accuracy, jamming and poor conveyance will occur, and there is a problem that the distance adjustment is troublesome.
[0009]
Therefore, it is also conceivable that the positions between the opposing spiral bodies are preliminarily provided with a scale corresponding to several kinds of standard-size printed matter, and the position can be adjusted according to the scale.
However, even if this is done, the above-mentioned problems occur when the scale is misplaced when the scale is adjusted, or when there is a large error in the set position even at the proper scale position. As a result, there was a problem with reliability.
In addition, when an irregular size is used, there is no scale to match it, so in this case the set is matched to the actual product, so there is a problem that the distance adjustment between the spirals is very troublesome. It was.
[0010]
The present invention has been made in view of the above-described problems, and even in a printed matter discharge and storage device using a spiral body that transports a printed matter to a storage portion while being held between opposing spiral bodies. It is an object of the present invention to be able to adjust the distance between spirals having a high height, and to easily adjust the distance between the spirals even for printed matter of an irregular size.
[0011]
[Means for Solving the Problems]
In order to achieve the above object, the present invention includes a plurality of spiral bodies that can hold both side edges of a printed material discharged from a paper discharge portion of a printing apparatus in a position moved in the apparatus body according to the size of the printed material. The printed matter is stored in the outer circumferential surface of each spiral body by rotating in a state where the printed matter is respectively held by a belt-shaped receiving portion formed in a spiral shape with a predetermined interval in the rotation axis direction of each spiral body. A small-size printed material discharge storage device that transports the image to the stack and stores it in a stacked state is configured as follows.
[0012]
The upper end portion of the rotating shaft of each spiral is protruded to the upper surface side of the apparatus body, and the upper end portion of the rotating shaft of the spiral body that holds one side edge of the printed material is placed at a predetermined position on the upper surface of the apparatus body. Attach one of a pair of side edge guides to be in contact with one side edge of a sheet of the same size as the set printed material, and attach the above paper to the upper end of the rotating shaft of the spiral that holds the other side edge of the printed material The other of the pair of side edge guides to be brought into contact with the other side edge of the sheet is attached, the attachment position of the pair of side edge guides to the rotation shaft of each spiral body, When the contact is made, the position of each helical body is set to a position for holding both side edges of the printed material transferred to the storage portion by the strip-shaped receiving portion.
[0013]
In this way, if the paper of the size to be printed is set at a predetermined position on the upper surface of the apparatus main body, and the pair of side edge guides are moved to the positions where they are in contact with both side edges of the paper, The spiral bodies are automatically in the ideal positions for holding the side edges of the printed material that are fed between the spiral bodies by the strip-shaped receiving portions whose positions are spirally formed.
[0014]
Further, in the small-size printed material discharge storage device, the rear end guide that is brought into contact with the rear end edge of the same size paper as the printed material set at the predetermined position is discharged from the paper discharge unit on the upper surface of the apparatus main body. It is preferable that the rear end fence for restricting the position of the printed material by fixing the rear end of the printed material stored in the storage portion in the rear end guide is fixed.
[0015]
Then, if the trailing edge guide is brought into contact with the trailing edge of the sheet set at a predetermined position on the upper surface of the apparatus main body, the trailing edge fence is brought into contact with the trailing edge of the printed material stored in the storage unit. The position of the printed matter is regulated.
Therefore, since the trailing edge fence can prevent the misalignment of the printed material stacked in the storage portion in the storage unit, even if the ink is in a dry state, the back of the ink is rubbed when the ink surface is rubbed due to the misalignment. Dirt is likely to occur, but it can be prevented.
[0016]
Further, in any one of the small-size printed matter discharge and storage apparatuses, the pair of side edge guides is provided with a protrusion that prevents the paper set on the upper surface of the apparatus main body from entering below the side edge guide. In addition to extending along the surface to be contacted, it is preferable to form a recess or a long hole into the upper surface of the apparatus main body so that the protrusions are movably fitted along the moving direction of the side edge guides.
[0017]
Then, when the pair of side edge guides abut against the both side edges of the paper set on the upper surface of the apparatus main body, the projections formed on the side edge guides become the side edge guides of the paper. By preventing entry into the lower side, the setting position of each side edge guide is determined to be an accurate position corresponding to the printed matter, so that each spiral body can be accurately set at an ideal position.
[0018]
Furthermore, in any one of the small-size printed matter discharge and storage devices, the first main abutment and the second abutment for causing the front end of the paper to abut and setting the predetermined position are provided on the apparatus main body. The upper surface of the apparatus main body and the apparatus main body are rotatably attached to the downstream side in the discharge direction of the printed matter, and the upper end is exposed to the upper surface of the apparatus main body one by one, or the upper surface or the rear cover of the apparatus main body Abutting and a second abutting are provided, and the first abutting is positioned downstream of the second abutting in the discharge direction of the printed matter and substantially positioned at the center of discharging the printed matter. Is positioned outside in the width direction of the printed matter with respect to the first butting.
[0019]
Further, the first printed matter front end restricting portion for restricting the position of the front end of the printed matter transferred to the storage unit in the apparatus main body and the first printed matter front end restricting portion are located outside in the width direction of the printed matter. A second printed matter front end restricting portion that is configured to substantially match the position of the printed matter restricting surface of the first printed matter front end restricting portion in the discharge direction with the printed abutment surface of the first abutment. The position in the discharge direction of the printed material regulating surface of the printed material leading edge regulating portion is made to substantially coincide with the printed material abutting surface of the second abutment.
[0020]
In this way, the first abutting is used for small-size paper such as a postcard size, and the second abutting is used for a relatively large size paper such as an envelope outside the fixed form. can do.
Therefore, even when the relatively large size paper is used, even when the spirals on both sides holding both side edges of the paper move away from each other and move upstream in the discharge direction. The paper set by being abutted against the second abutment on the upper surface of the apparatus main body is located at a position where the set position is shifted to the upstream side in the discharge direction from the first abutment. Since the second printed material front end restricting portion is provided so as to substantially coincide with the ejection direction in the butting of 2, the printed material fed between the plurality of spiral bodies is the first butted and second butted The position is shifted to the upstream side in the discharge direction of the printed matter by the difference in the discharge direction.
As a result, both side edges of the printed matter can be held in a balanced manner by the plurality of spiral bodies, so that drooping of the printed matter on the front end side can be prevented.
[0021]

The spiral bodies 25A and 25B and 26A and 26B have the same shape. The spiral bodies 25A and 25B are shown in FIG. 9A, and the spiral bodies 26A and 26B are shown in FIG. 9B (FIG. 9). (A) and (b), both shaft portions 25a and 26a are not shown), and the outer peripheral surface of the member formed in a cylindrical shape (may be a columnar shape). The belt-shaped receiving portions 25b and 26b formed in a spiral shape with a predetermined interval along the longitudinal direction (rotational axis direction) are formed in a projecting manner, and are 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.

It is preferable to set the interval as short as possible so that the printing sheets in the state where they are not in contact with those adjacent to each other in the vertical direction can reduce the height of the apparatus.
[0033]
However, since the interval between the lower receiving portions 25b and 26b on the receiving side of the printing paper needs to prevent the receiving printing paper from being jammed, each pitch of the receiving portions 25b and 26b in the intermediate portion is required. The pitch P2 is larger than P1.
Further, the interval between the receiving portions 25b and 26b in the rotation axis direction, and the pitch (interval) P3 of the final portion on the upper side for feeding the printing paper to the storage portion are also intermediate portions of the spiral bodies 25A, 25B, 26A and 26B.

Then, the first intermediate gear 34 that meshes with the gear portion 32a of the intermediate pulley 32 that rotates clockwise in FIG. 14 rotates in the direction of the arrow. Accordingly, since the pulley gear 37 that meshes with the first intermediate gear 34 rotates in the clockwise direction indicated by the arrow, the double pulley 66 rotates by the timing belt 63 that rotates in the same direction, and the spiral body 26B rotates in the clockwise direction. .
[0053]
Further, as the first intermediate gear 34 rotates in the direction indicated by the arrow, the second intermediate gear 35 meshing with the first intermediate gear 34 rotates in the clockwise direction, and the pulley gear 38 meshing with the second intermediate gear 35 rotates in the counterclockwise direction indicated by the arrow. 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.
[0054]
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. 7, 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.
[0055]
In addition, the helical body rotating device 90 shown in FIG. 14 can move the second intermediate gear 35 and the pulley gear 38 even if the helical bodies 25B and 26B are moved toward and away from each other by rotating around the support shafts 75 'and 79', respectively. 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. As shown in FIGS. 10 and 12, the small-size printed matter discharge and storage device 2 is provided with a belt conveying device 95 at an entrance portion for receiving printing paper on the bottom plate 45.
[0056]
In the belt conveying device 95, when the belt driving motor 91 shown in FIG. 10 rotates the timing belt 92, the pulleys supporting the conveying belts 96 and 97 are rotated, and the two conveying belts 96 and 97 are indicated by arrows F. Rotate in the direction.
Then, due to the conveying force of the conveying belts 96 and 97, the printing paper P is conveyed between the spirals 25A and 26A and between the spirals 25B and 26B as shown in FIG. I hit it.
A sensor 19 for detecting printing paper passing therethrough is disposed between the conveyor belts 96 and 97, and a sensor 19 ′ for detecting the presence of printing paper is also provided in the vicinity of the rear lower cover 52. It is arranged.
[0057]
A pair of inlet guide plates 21 and 22 are provided on both sides of the belt conveying device 95, and the inlet guide plate 21 is fixed to the inner surface of the unit support 53 of the spiral unit 50 shown in FIG. The guide plate 22 is fixed to the inner surface of the unit support 58 of the spiral unit 60 with screws (see also FIG. 10).
Further, as shown in FIG. 12, an intermediate guide plate 23 is disposed between the spiral bodies 25A and 25B, and an intermediate guide plate 24 is disposed between the spiral bodies 26A and 26B. The intermediate guide plate 23 is shown in FIG. The inner guide plate 24 is screwed and fixed to the inner surface of the unit column 59 of the spiral unit 60 as shown in FIG.
[0058]
On the other hand, above the spiral bodies 25A, 25B and 26A, 26B, a storage section 5 is provided for storing printing paper raised by the spiral bodies.
The storage portion 5 is a space portion formed at the upper part of each of the spiral unit 50 and 60 described in FIG. 6, and is stored on the upper inner surfaces of the unit columns 58 and 59 of the spiral unit 60 as shown in FIG. The guide plate 6 is fixed with screws, and similarly, a storage guide plate (not shown) corresponding to the storage guide plate 6 is also screwed onto the upper inner surfaces of the unit columns 53 and 54 on the spiral unit 50 side in FIG. It is fixed. In addition, as shown in FIG. 11, the small-size printed matter discharge and storage device 2 has a top plate that constitutes the main body of the upper ends of the shaft portions 25a and 26a, which are the rotation shafts of the spiral bodies 25A, 25B, 26A and 26B. Projected to the upper surface side of 46.
[0059]
Then, as shown in FIG. 1, the upper end portion of each shaft portion 25a of the spiral body 25A, 25B that holds one side edge Pa of the printing paper P is placed on the top plate 46 to form the exterior portion of the apparatus main body. On the upper surface of the upper exterior cover 49, the front end portion is abutted against the abutting portion 51a which is the first abutting portion formed on the rear upper cover 51 with a predetermined width so as to substantially coincide with the discharge center of the printing paper P. As a result, one side edge guide 101 that is brought into contact with one side edge Psa of the printing paper Ps set at a predetermined setting position (paper having the same size as the printing paper P and before printing) is attached.
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.
[0060]
The paired side edge guides 101 and 102 are linked to the left side spiral guides 25A and 25B in FIG. 1 and the side edge guide 102 is linked to the right side spiral guides 26A and 26B, respectively. Separate.
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 contacting the side edges Psa and Psb of the printing paper Ps set at the set position (the position shown in FIG. 1), the positions of the spiral bodies 25A, 25B, 26A and 26B are the strip-shaped 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. 10).
[0061]
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 and 26A shown in FIGS. 25B and 26B 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.
[0062]
Specifically, as shown in FIG. 1, 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.
[0063]
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.
[0064]
As shown in FIG. 3, the side edge guides 101 and 102 are guide grooves 111, 112, 113 formed in an arc shape on the upper surface of the upper exterior cover 49 along the moving direction of the spiral bodies 25A, 25B, 26A and 26B. 2 and 114, projections 101c, 101d and 102c, 102d respectively projecting from the lower surfaces of both ends in the longitudinal direction are movably fitted, as shown in FIG.
[0065]
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 formed on the lower surfaces of the respective convex portions 101c, 101d, 102c and 102d, and the spiral bodies 25A, 25B, 26A and The shaft portions 25a and 26a of 26B are respectively fitted.
[0066]
Further, as shown in FIG. 1, the side edge guides 101 and 102 also have 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.
[0067]
Then, the projections 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.
[0068]
As described above, the side edge guide 101 is provided with the projection 103 as shown in FIG. 1, 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.
[0069]
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.
Further, as shown in FIG. 5, the small-size printed matter discharge and storage device 2 forms a long hole 46e in the top plate 46 along the conveyance direction of the printing paper, and a rear end fence 7 as shown in FIG. Is slidable in the direction of arrow G.
[0070]
Also, as shown in FIG. 3, the top end of the upper exterior cover 49 is set to a predetermined position by abutting the leading end of a sheet of the same size as the sheet to be printed (see printing sheet Ps in FIG. 1). A pair of butting protrusions 49c and 49c that serve as a second butting for projecting are provided.
Then, the abutting portion 51a of the rear upper cover 51 serving as the first abutting described above is positioned downstream of the pair of abutting protrusions 49c and 49c in the discharge direction of the printing paper (left side in FIG. 3). ing.
[0071]
Further, the pair of abutting protrusions 49c and 49c are positioned outside the abutting portion 51a in the width direction of the printing paper, and are arranged symmetrically with respect to the discharge center of the printing paper. A distance WL is set between the pair of butting protrusions 49c and 49c.
Therefore, the small-size printed matter discharge and storage device 2 has a butting portion 51a when the width WPs of the printing paper (see printing paper Ps in FIG. 1) set on the upper surface of the upper exterior cover 49 is “WPs ≦ WL”. When the width WPs is “WPs> WL”, a pair of abutting protrusions 49c and 49c are used.
[0072]
Further, the top surface of the upper exterior cover 49 abuts against the rear edge of the printing paper set at a predetermined setting position by the front end being abutted against the abutting portion 51a or the pair of abutting projections 49c, 49c. The trailing edge guide 105 to be moved is provided so as to be movable along the discharge direction (arrow J direction) of the print paper discharged from the paper discharge portion of the stencil printing apparatus.
[0073]
Then, the rear end fence 105 that abuts the rear end (right end side in FIG. 10) of the printing paper stored in the storage unit 5 described in FIG. 10 and regulates the position of the printing paper is fixed to the rear end guide 105. are doing.
As shown in FIG. 3, the rear end guide 105 is provided with a protrusion 105a that fits into the long hole 49b of the upper exterior cover 49 and is fixed to the rear end fence 7. Therefore, the rear end edge of the printing paper is the rear end. It does not enter the lower surface of the guide 105.
[0074]
According to the small-size printed matter discharge storage device 2, the rear end guide 105 is slid in the direction indicated by the arrow G in FIG. If the trailing edge of the printing paper set in the set position is brought into contact with the trailing edge of the printing paper, the trailing edge fence 7 comes into contact with the trailing edge of the printing paper stored in the storage unit 5 to be a position for regulating the printing paper.
[0075]
Therefore, since the trailing edge fence 7 can prevent the printing paper stacked in the storage portion 5 from being stacked, the ink surface of the printing paper is generally rubbed due to the stacking error even when the printing paper is dried to some extent. However, it is possible to prevent the ink from becoming dirty.
In particular, when envelopes are stacked, the rear upper cover 51 side is stacked higher than the upstream side in the conveyance direction in the storage unit 5 because the envelope is conveyed with the folded side of the envelope, that is, the thick side as the front end. In other words, the rear end fence 7 is effective because the rear end fence 7 is liable to be loaded.
[0076]
By the way, the small-size printed material discharge storage device 2 is transferred to the storage unit 5 (FIG. 10) in the main body frame (device main body) 40 so as to show a cross-sectional shape along the line KK in FIG. The first printed matter leading edge regulating portion 52a that regulates the position of the leading edge of the printed paper P to be printed, and the second that forms a pair positioned on the outside in the width direction of the printing paper P with respect to the first printed matter leading edge regulating portion 52a. The printed matter front end regulating portions 52b and 52b are provided.
[0077]
And the position of the discharge direction (left-right direction in FIG. 16) of the printed matter regulating surface 52c of the first printed matter leading edge regulating portion 52a is set to the position of the abutting portion 51a formed on the rear upper cover 51 as shown in FIG. The printed product abutting surfaces 51b are substantially coincided with each other, and the positions of the printed matter regulating surfaces 52d and 52d of the second printed matter leading edge regulating portions 52b and 52b in the discharge direction are set to the printed matter abutting surfaces of the pair of abutting projections 49c and 49c. 49d and 49d.
[0078]
When the small-size printed material discharge storage device 2 is used by being mounted on a stencil printing apparatus 1 as shown in FIG. 4, for example, it is first placed on the discharge tray 17 of the stencil printing apparatus 1 as shown in the figure. Set to a predetermined position.
Next, in order to reliably support 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. 12, the knob 83 shown in FIG. 13 is rotated, As shown in FIG. 1 (showing a case where the printing paper Ps is set against the abutting portion 51a), the pair of side edge guides 101 and 102 are in contact with both side edges Psa and Psb of the printing paper Ps. To move.
[0079]
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. Optimum distance suitable for transporting the printing paper P in which both side edges Pa and side edges Pb of the paper P are held about 2/3 (about 3 mm) by the receiving portions 25b and 26b of the spiral bodies 25A, 25B and 26A, 26B, respectively. become.
Further, according to the size of the printing paper to be used, the position of the rear end fence 7 shown in FIG. 10 is changed to a predetermined set position on the upper exterior cover 49 shown in FIG. The printing paper Ps set on the printing paper Ps is adjusted so as to come into contact with the rear edge of the printing paper Ps so that the printing paper stored in the storage unit 5 does not shift.
[0080]
In this state, when the power switch of the small size printed material discharge storage device 2 shown in FIG. 3 is turned on, the small size printed material discharge storage device 2 enters a standby state.
Here, when a document to be printed is set on the document reading device of the stencil printing apparatus 1 shown in FIG. 4 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.
[0081]
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.
Next, plate printing is performed on a sheet for printing (the same size as the postcard), and the first printed material (hereinafter referred to as a printed material) is sent to the small size printed material discharge storage device 2 by the discharge conveyance belt 16. . Note that this printing with printing is printing performed to familiarize the first sheet with ink because the ink is not sufficiently familiar with the stencil master.
[0082]
As shown in FIG. 12, the printing material is conveyed by a belt conveying device 95 until the tip abuts against the inner surface of the rear lower cover 52, and at that time, both side edges are the receiving portions of the spiral bodies 25A, 25B, 26A and 26B. It is supported in the state accepted by 25b and 26b.
When the sensor 19 detects the passage of the plate-printed material and the sensor 19 ′ detects that the plate-printed material has arrived, the pulse motor 29 described with reference to FIG. 14 is driven, and the spiral bodies 25A, 25B, 26A and 26B are moved. The plate-printed printed material is conveyed upward by a distance corresponding to one stage of the receiving portions 25b and 26b by rotating once.
[0083]
At that time, the rotating directions of the rotating spiral bodies 25A, 25B, 26A and 26B are respectively opposite to each other as shown in FIG. 12, with the opposing spiral bodies 25A and 26A and 25B and 26B being respectively rotated. Accordingly, the plate-printed printed matter rises along the rear lower cover 52 while the front end is pressed against the rear lower cover 52.
[0084]
Next, the operator first opens the rear upper cover 51 in the direction of arrow B in FIG. 3, and then opens the rear lower cover 52 in the direction of arrow C (see also FIG. 10). Remove and check the image and print position. And if necessary, what plate is installed in the stencil printing device when correcting the ink density or the printing section deviation with respect to the printing paper, or when printing again after a while after printing. Make a proof print to see what is being done.
[0085]
Here, if there is no problem with the printing and test printing, the printing and trial printing paper placed on the upper part 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 that is 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.
[0086]
The printing paper P is transported between the spirals 25A and 26A and between 25B and 26B shown in FIG. The edges Pa and Pb are supported in a state of being received by the receiving portions 25b and 26b, respectively.
When the printing paper P passes through the belt conveying device 95, the sensor 19 detects it, and each time the sensor 19 'detects that the printing paper P has arrived, the pulse motor 29 detects the spiral bodies 25A and 25B. , 26A and 26B are rotated by one rotation, and the printing paper P is sequentially conveyed upward by a distance corresponding to one stage of the receiving portions 25b and 26b.
[0087]
Such operations are sequentially repeated, and when printing on the predetermined number of set printing papers P is completed, as shown in FIG. 15, the uppermost receiving portions 25b of the spiral bodies 25A, 25B, 26A, and 26B, respectively. , 26b is stacked on the last receiving portion 25b ', 26b' of the final part to be sent to the storage unit 5 provided above, and the other printing paper P is placed at each stage of the spiral body. It will be in the state supported by the receiving parts 25b and 26b.
[0088]
Here, when the printing is ended, a printing end switch provided in the operation unit 8 (FIG. 3) of the small-size printed material discharge storage device 2 is pressed. Then, the pulse motor 29 of FIG. 10 rotates and the spiral bodies 25A, 25B, 26A and 26B rotate, so that all the printing paper P supported by the receiving portions 25b and 26b of the respective stages is stored in the storage portion 5. Is raised and stacked there.
[0089]
Therefore, when the rear upper cover 51 shown in FIG. 15 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. 3 and the top plate 46 shown in FIG. Therefore, if a finger is put there and a bundle of printing paper P stacked in the storage unit 5 is pulled out from the top and bottom, it can be easily taken out.
[0090]
As described with reference to FIGS. 9 (a) and 9 (b), the pitch P3 of the final portion for sending the printing paper of the receiving portions 25b and 26b of the helical bodies 25A, 26A, 25B and 26B to the storage portion is set to each of the pitches P3. Since it is larger than the pitch P1 of the middle part of the spiral body, as shown in FIG. 15, it is held by the printing paper P stacked in the storage part 5 and the respective receiving parts 25b and 26b of the spiral body adjacent in the vertical direction. Since the space between the printing paper P that is still in the transfer process is widened, the printing paper P stacked in the storage unit 5 is taken out together with the fingers placed under the printing paper P and held. Can do.
[0091]
By the way, as described with reference to FIG. 3, the small-size printed matter discharge and storage device 2 changes the setting position of the printing paper set on the upper exterior cover 49 in accordance with the size of the printing paper to be used. For example, when using printing paper of a small size such as a postcard, the abutting portion 51a of the rear upper cover 51 is used.
Further, when using a relatively large size printing paper such as a non-standard envelope, a pair of butting protrusions 49c and 49c are used.
[0092]
Therefore, when using a relatively large size printing paper as in the latter case, the small-size printed matter discharge and storage device 2 has a spiral body 25A on both sides that holds both side edges of the printing paper as described in FIG. 26A and 25B and 26B are rotated around the support shafts 76, 80, 75 and 79 while being separated from each other so as to move to the upstream side (lower side in FIG. 13) in the printing paper discharge direction. Therefore, the printing paper in which both side edges are held by the respective spiral bodies tends to sag at the leading end side, but the sag can be prevented.
[0093]
That is, in the case where the printing paper is always abutted against the abutting portion 51a shown in FIG. 10, as described above, the spirals 25A and 26A and 25B and 26B are spaced apart from each other while rotating in an arc. As the paper moves to the upstream side in the paper discharge direction, the holding positions of the spiral bodies 25A and 26A and 25B and 26B with respect to the printing paper P are biased to the right in FIG. Therefore, the printing paper P is likely to hang down on the leading end side (left side in the figure).
[0094]
However, in the small-size printed material discharge storage device 2, as described above, a relatively large size, that is, a printing paper whose width WPs is larger than the distance WL between the pair of abutting protrusions 49c and 49c in FIG. Since the abutting projections 49c and 49c are used, the printing paper is a small size printing paper by the distance L between the abutting projection 49c and the abutting portion 51a as shown in FIG. The setting position is shifted to the right in FIG.
[0095]
The printed material abutting surfaces 49d and 49d of the pair of abutting protrusions 49c and 49c are positioned on the printed material regulating surfaces 52d and 52d of the second printed material leading edge regulating portions 52b and 52b in the discharge direction of the printing paper as described above. Is almost the same.
Accordingly, as shown by the solid line in FIG. 17, the larger-size printing paper PL is shifted by the distance L to the upstream side (right side in the figure) in the discharge direction, so that the spiral bodies 25A, 26A and 25B are printed after printing. And 26B can be held from both sides in a balanced manner by the spiral bodies 25A and 26A and 25B and 26B. Accordingly, the leading edge of the printing paper PL can be prevented from sagging so that no rubbing occurs between the papers, so that no settling occurs.
[0096]
【The invention's effect】
As described above, according to the small-size printed matter discharge and storage device according to the present invention, even a device using a spiral body that transports a printed matter to a storage unit while being held between opposing spiral bodies, By simply bringing a pair of side edge guides into contact with both side edges of the same size paper as the printed material set at a predetermined position on the upper surface, each side of the printed material that is automatically fed between the spirals is held. It can be the ideal position possible.
Therefore, it is possible to adjust the distance between the spirals with high reliability, and even when printing using an irregular size paper, each spiral can be easily set at an ideal position. It is possible to prevent non-feeding from occurring.
