Description

  The present invention relates to a rotary press used for printing newspapers and the like.

  For example, as described in Patent Document 1, a rotary press includes a paper feeding unit that continuously feeds paper, a printing unit that prints on paper fed from the paper feeding unit, and paper printed by the printing unit. And a folding part that forms a cloth shape as a printed matter.

  In these rotary presses, in order to increase printing efficiency, the use of double-width paper (4 pages width in newspapers) has become the mainstream in recent years. Since the width is almost the same, the width of the paper used in the rotary press is also constant. Therefore, the conventional rotary press has been designed exclusively for a specific paper width.

However, when looking overseas, there are various page widths even if it is a newspaper, and media other than newspapers may be printed, and the width of paper used in a rotary press is not constant. For this reason, a rotary press designed and manufactured in Japan may not be used overseas, and in that case, it was necessary to separately design and manufacture a rotary press exclusively for the paper width.

  Embodiments of the present invention will be described below based on examples shown in the drawings.

  FIG. 1 is a diagram of an entire rotary press according to the present invention as viewed from the operation side.

  The rotary press shown in FIG. 1 processes newspaper paper having a width of 4 pages, and includes three sets of paper feeding units A1 to A3 and printing units B1 to B3. That is, the paper fed from the paper feeding unit A1 is the printing unit B1, the paper fed from the paper feeding unit A2 is the printing unit B2, and the paper fed from the paper feeding unit A3 is the printing unit B3. Each is printed. Among these, the printing unit B1 is for full-color printing and includes an eight-couple printing roll set. The printing sections B2 and B3 are for printing one black color or two colors, black and single color, and include four couples of printing roll sets.

  Each of the printing sections B1 to B3 is provided with an outfeed paper pressing device 10 that applies tension to the printed paper. The paper exiting the outfeed paper pressing device 10 of each printing unit B1 to B3 is conveyed to the folding unit D via the rail frame unit C.

  In the rail frame portion C, a slitter (reference numeral 20 in FIG. 3 to be described later) that slits the center of a four-page width paper into two to divide it into two pages and a paper that is divided into two by this slitter are overlapped. A turn bar 30 for changing the traveling direction of the paper is provided. Three sets of these slitters and turn bars 30 are provided so as to correspond to the printing sections B1 to B3. Then, the six strips of paper that are two pages wide by the three sets of slitters and turn bars 30 are adjusted in phase in the direction of travel by the transport roll group 40 and overlapped immediately before the folding portion D to form one strip of two pages wide. Paper. In some cases, the slitter of the turn bar 30 portion may not be used. In this case, three sheets of four pages wide are stacked just before the folding portion D to form one sheet of four pages wide.

  The folding part D is provided with a wallis 50 that draws the paper from the rail frame part C into the folding part D and a slitter 60 that slits the paper from the wallis 50. In addition, the slitter 60 may not be used similarly to the slitter of the above-mentioned turn bar 30 part.

  The paper drawn by the wallis 50 is vertically folded by the former 70, and the vertical folding portion is sandwiched by the nipping roller device 80, so that a crease is reliably attached. Thereafter, the paper is cut into one page length and folded into a distribution shape (printed newspaper style) as a printed matter. The newspapers are then transferred to the delivery belt one by one and carried to a predetermined location.

  The rotary press shown in FIG. 1 has a position adjustment mechanism that adjusts the position of the member that contacts the paper in the printing parts B1 to B3, the rail frame part C, and the folding part D in response to a change in the width of the paper to be used. Is provided. Specifically, there are four types of paper widths, 1640 mm, 1562 mm, 1440 mm, and 1360 mm, which are referred to as “A roll”, but it can also be applied to A rolls of 1702 mm and 1280 mm. Moreover, about C volume and D volume, it can be used by the setting of A volume.

  Hereinafter, the position adjusting mechanism of each part will be described.

  2A and 2B show a position adjustment mechanism in the outfeed paper pressing device 10 of the printing units B1 to B3. FIG. 2A is a front view thereof, and FIG. 2B is a view taken along the line AA in FIG.

  The outfeed paper pressing device 10 is a device that applies tension to the printed paper as described above, and includes a paper pressing roll 11 for that purpose. The paper pressing roll 11 is disposed so as to contact the non-printing portion of the paper. Accordingly, when printing with a width of four pages as in the embodiment, five paper pressing rolls 11 are arranged. These paper presser rolls 11 are provided so as to be movable along the axial direction (paper width direction) of the roll support shaft 12, and the positions of the paper presser rolls 11 in the paper width direction are adjusted according to the width of the paper to be used. In order to enable this, a clamp lever 13 is provided as a position adjusting mechanism. That is, by loosening the clamp lever 13, the paper pressing roll 11 can be moved in the paper width direction, and after moving to a predetermined position suitable for the width of the paper to be used, the clamp lever 13 is tightened to fix the predetermined position. . The paper pressing roll 11 is movable in the axial direction with respect to the roll support shaft 12 and has a structure that does not rotate around the axis.

  In FIG. 2, the position of the paper pressing roll 11 corresponding to the maximum width (1640 mm) of the paper used in this embodiment is indicated by a solid line, and the position of the paper pressing roll 11 corresponding to the minimum width (1360 mm) is indicated by a broken line. Show. Even if the width of the paper to be used is changed, the central position of the paper does not change. Therefore, it is not necessary to adjust the position of the central paper pressing roll 11.

  3A and 3B show a position adjusting mechanism in the turn bar 30 of the rail frame portion C. FIG. 3A is a plan view thereof, FIG. 3B is a partial arrow view in the A direction of FIG. It is a partial arrow line view of B direction.

  In the rail frame part C, the four-page paper is divided into two pages × two sheets by the slitter 20, and one of these two sheets (the driving side GS) is attached at an angle of 45 degrees. The turn direction of the turn bar 30 including the two inclined bars 30a and 30b changes the traveling direction so as to overlap the other (operation side HS) paper. In the case of volume C, it is divided into two pages having a width of two pages and a width of one page.

  At this time, even if the width of the paper to be used is changed, the position of the center is not changed, so that the position of the slitter 20 is fixed. On the other hand, when the width of the paper to be used is changed, the paper width of the turn bar 30, that is, the inclined bars 30a and 30b, is changed in order to change the traveling direction of the paper on the driving side GS to overlap the paper on the operation side HS. It is necessary to adjust the position of the direction. Therefore, in the example of FIG. 3, the inclined bars 30 a and 30 b are provided so as to be movable along the axial direction (paper width direction) of the inclined bar support shaft 31, and the position adjustment mechanism of the inclined bar 30 a on the entry side (drive side GS). By providing a motor 33 as a position adjusting mechanism for the manual knob 32 and the outlet (operating side HS) inclined bar 30b, the position of the inclined bars 30a, 30b in the paper width direction can be adjusted according to the width of the paper to be used. Yes.

  In this embodiment, as shown in FIGS. 3B and 3C, a scale plate 34 with a scale corresponding to the width of the paper to be used is fixed to the frame F side, and the indicator needle 35 is attached to the tilt bar. It is fixed on the 30a, 30b side. Then, by operating the manual knob 32 and the motor 33, the inclined bars 30a and 30b are moved in the paper width direction, and the position of the indicating needle 35 that moves with the inclined bars 30a and 30b is adjusted to the scale position corresponding to the width of the paper to be used. The positions of the inclined bars 30a and 30b can be adjusted to predetermined positions suitable for the width of the paper to be used.

  Further, with respect to the inclined bar 30b on the operation side HS, fine adjustment of the position is also performed when fine adjustment of the paper overlapping position is performed during operation. The fine adjustment of the position of the inclined bar 30b during operation is performed by operating the motor 33 while confirming the overlapping state of the paper on the exit side of the turn bar 30. Note that such fine adjustment of the position of the inclined bar 30b has been performed conventionally, but this conventional fine adjustment is only for fine adjustment of the overlapping position of the paper, It is not for dealing with a change in the width of the paper to be used, and the conventional fine adjustment cannot cope with a change in the width of the paper to be used.

  FIG. 4 is a front view showing a position adjusting mechanism in the wallis 50 of the folding part D. FIG.

  The wallis 50 is a roller member for drawing the paper from the rail frame part C into the folding part D, and is arranged so as to contact the non-printing part of the paper. In the present embodiment, eight Wallis 50 are provided so that not only the width of 4 pages but also the width of 2 pages and tabloid paper can be handled.

  In the case of paper with a width of 4 pages, the wallis 50 excluding the wallis 50 at both ends are adjacent to each other. These wallis 50 are provided so as to be movable along the axial direction (paper width direction) of the wallis support shaft 51 via the wallis arm 50a, and each wallis 50 (wallis arm 50a) corresponds to the width of the paper to be used. In order to make it possible to adjust the position in the paper width direction, a lock bolt 52 and a clamp lever 53 are provided as a position adjustment mechanism. That is, by loosening the lock bolt 52 and tightening the clamp lever 53, the hole diameter of the wallis arm 50a is expanded, and the wallis 50 can move smoothly in the paper width direction. Then, after moving the wallis 50 to a predetermined position suitable for the width of the paper to be used, the clamp lever 53 is loosened and the lock bolt 52 is tightened to fix the wallis 50 to the predetermined position. Even if the width of the paper to be used is changed, the central position of the paper does not change. Therefore, it is not necessary to adjust the positions of the two central Wallis 50. In the case of paper having a width other than 4 pages, the unused wallis 50 is expanded by expanding the wallis arm 50 a and rotating it around the wallis support shaft 51.

  In the embodiment, the stopper 54 is provided so that the wallis 50 can be easily positioned at a position suitable for the maximum width (1640 mm) of the paper to be used, and the wallis at a position suitable for the minimum width (1360 mm) of the paper to be used. A stopper 55 is provided so that 50 can be easily positioned. When the width of the paper to be used is the maximum width (1640 mm), a wallis 50 other than the two central wallis 50 is abutted against the stopper 54 side, and when the width of the paper to be used is the minimum width (1360 mm), the center The wallis 50 other than the two wallis 50 are abutted against the stopper 55 side. When the paper width is between the maximum width and the minimum width, the position of the wallis 50 is adjusted according to the paper width using a gauge or the like with reference to the position of the stopper 54 or the stopper 55.

  FIG. 5 is a front view showing a position adjusting mechanism in the slitter 60 of the folding part D. FIG.

  In FIG. 5, three slitters 60 are provided so that paper of 4 pages width can be divided into 1 page width. These slitters 60 are provided so as to be movable along the axial direction (paper width direction) of the slitter support shaft 61 via the bracket 60a, and each slitter 60 (bracket 60a) corresponds to the width of the paper to be used. In order to adjust the position in the paper width direction, a lock bolt 62 is provided as a position adjustment mechanism. That is, the slitter 60 can be moved in the paper width direction by loosening the lock bolt 62. After the slitter 60 is moved to a predetermined position suitable for the width of the paper to be used, the lock bolt 62 is tightened to the predetermined position. Fix it. Even if the width of the paper to be used is changed, the center position does not change, and therefore there is no need to adjust the position of the center slitter 60.

  In the embodiment, a stopper 63 is provided at a position suitable for the maximum width (1640 mm) of the paper to be used so that the slitters 50 at both ends can be easily positioned, and a position suitable for the minimum width (1360 mm) of the paper to be used. A stopper 64 is provided so that the slitters 60 at both ends can be easily positioned. When the width of the paper to be used is the maximum width (1640 mm), the slitters 60 at both ends are abutted against the stopper 63 side. When the width of the paper to be used is the minimum width (1360 mm), the slitters 60 at both ends are Hit it. When the paper width is between the maximum width and the minimum width, the position of the slitter 60 is adjusted according to the paper width using a gauge or the like with the position of the stopper 63 or the stopper 64 as a reference.

  FIG. 6 is a view of the position adjustment mechanism in the former 70 of the folding part D as viewed from the operation side of the folding part D. FIG.

  As shown in the figure, in this embodiment, two formers 70 are provided adjacent to each other in parallel so that two sheets of two pages wide can be vertically folded along the running direction. Each former 70 is provided so as to be movable along the paper width direction, and each former 70 is adjusted as a position adjustment mechanism so that the position in the paper width direction can be adjusted according to the width of the paper to be used. A handle 71 is provided. By rotating the adjustment handle 71, the former 70 is moved to a predetermined position suitable for the width of the paper to be used.

  Further, in the embodiment, the sub-plate 72 is detachably provided on the side surface on the adjacent side of each former 70 so as to secure a large movement allowance of each former 70 in the paper width direction. In the embodiment, the sub plate 72 is attached when the paper width is 1562 mm or more, and the sub plate 72 is removed when the paper width is 1440 mm or less. That is, when the paper width is small, by removing the sub plate 72, the formers 70 can be moved greatly in the direction approaching each other. Note that the sub-plate 72 can be attached and detached by, for example, a bolt.

  FIG. 7 is a front view showing a position adjusting mechanism in the nipping roller device 80 of the folding part D. FIG.

  The nipping roller device 80 includes one roller set 80a and the other roller set 80b opposite to the roller set 80a. As described above, the paper folded vertically by the former 70 is sandwiched between the roller sets 80a and 80b, and the folds are formed. It is an apparatus for attaching securely, and in the embodiment, it is provided at three places as shown in FIG.

  One roller set 80a includes a nipping roller (diamond roller) 81 for sandwiching a paper fold as shown in FIGS. 7A to 7D, and a nippin for sandwiching the free end of the paper opposite to the fold. A grawler (diamond roller) 82 is provided, and a split collar 83 that is in light contact with the paper is provided between the nipping rollers 81 and 82 and outside the nipping roller 82. Of these, the split collar 83 adjacent to the outside of the nipping roller 82 is integrated with the nipping roller 82, and the split collar 83 adjacent to the nipping roller 81 is integrated with the nipping roller 81. At least the nipping roller 81 and the split collars 83 on both sides thereof are provided to be movable along the axial direction (paper width direction) of the roller support shaft 84, and adjust the position in the paper width direction according to the paper width. Therefore, a lock bolt 85 is provided as a position adjustment mechanism. By loosening the lock bolt 85, the nipping roller 82 and the split collar 83 can be moved in the paper width direction. After moving to a predetermined position suitable for the width of the paper to be used, the lock bolt 85 is tightened to the predetermined position. Fix it.

  7A shows a case where the paper width is 1640 mm, FIG. 7B shows a case where the paper width is 1562 mm, FIG. 7C shows a case where the paper width is 1440 mm, and FIG. 7D shows a case where the paper width is 1360 mm. When the paper width is 1440 mm or less, one split collar 83 is removed as shown in FIGS. 7C and 7D.

  FIG. 7E shows the other roller set 80b. The other roller set 80b includes a nipping roller 81a facing the nipping roller 81 of one roller set 80a and a nipping roller 82 of one roller set 80a. And a wide nipping roller 82a corresponding to the moving width thereof, and a split collar 83 similar to the one roller set 80a.

  The paper (vertically folded paper) that has passed through the nipping roller device 80 is cut into one page length by the jaw folder 100 shown in FIG. 6, and is folded into a distribution shape (printed newspaper style) as a printed matter.

  The jaw folder 100 includes a saw cylinder 101, a folding cylinder 102, and a holding cylinder 103. In a newspaper rotary press, the circumference ratio of these three cylinders is 2: 3: 3. Since the configuration of these three cylinders is well known, the detailed configuration is not shown in the figure, but the saw cylinder 101 has two sets of saws, and the folding cylinder 102 has three sets of rubber bases, a needle mechanism and a tucker blade. It has been incorporated. The holding body 103 is provided with three sets of holding devices (a fixed jaw plate and a movable jaw plate having a spring).

  The paper is pulled by the needle mechanism of the folding cylinder 102, moves along the surface of the folding cylinder 102, is cut by contact with the saw table of the saw cylinder 101, and then contacts between the folding cylinder 102 and the holding cylinder 103. Then, the tucker blade protrudes from the folding cylinder 102, and the holding device of the holding cylinder 103 holds the central portion of the paper. At this time, the needle mechanism of the folding cylinder 102 comes out of the paper with good timing. The paper folded horizontally by the holding device advances in the rotation direction of the holding cylinder 103, leaves in the vicinity of the delivery fan 90, and is dropped by the delivery fan 90.

  FIG. 8 is an explanatory diagram showing the relationship between the needle placement and the paper width in the needle mechanism of the folding cylinder 102 described above. As shown in the figure, the needle 102a is arranged so as to be able to handle any paper width from the maximum width (1640 mm) to the minimum width (1360 mm) of the paper used in this embodiment. In addition, in this needle mechanism, since it is folded in 1 page width (1/4 width of A volume) of each paper, it is the paper width shown in figure. A broken line needle 102a corresponds to a case where the width of the paper to be used is 1702 mm.

  FIG. 9 is an explanatory view showing a fan position adjusting mechanism in the delivery fan 90. As shown in the figure, the delivery fan 90 receives one copy of the paper folded into a distribution shape (the appearance of the newspaper to be delivered) by the above-described jaw folder 100 one by one, and the fan 91 is used to hold the paper. Prepare. The fan 91 is provided with an interval in the circumferential direction of the delivery fan 90 as shown in FIG. 6, and is provided with an interval in a direction orthogonal to the circumferential direction of the delivery fan 90 as shown in FIG. It is done.

  Here, when the width of the paper to be used changes, the width of the printed matter to be held by the fan 91 of the delivery fan 90 also changes. Therefore, in order to hold this reliably, the direction orthogonal to the circumferential direction of the delivery fan 90 That is, it is preferable that the distance between the fans 91 in the width direction of the printed material can be adjusted. Therefore, in the present embodiment, of the four fans 91, the two fans 91 on the driving side of the folding part D can be moved along the direction perpendicular to the circumferential direction of the delivery fan 90 (the left-right direction in FIG. 9). The position (interval) can be adjusted. Specifically, a fan moving boss fixing bolt 92 is provided as a position adjusting mechanism, and by loosening the fan moving boss fixing bolt 92, the two fans 91 on the driving side FGS can be moved together with the fan moving boss 93 and used. After moving to a predetermined position suitable for the width of the paper (the width of the printed matter), the fan moving boss fixing bolt 92 is tightened to fix the predetermined position.

  In the present embodiment, when the paper to be used has a minimum width (1360 mm), the interval between the fans 91 is narrowed as the position shown in FIG. 9A, and other than that, the position of the fan 91 is set as the position shown in FIG. Increase the spacing.

  Further, in this embodiment, a stopper is provided so that the fan 91 can be easily positioned at the positions shown in FIGS. That is, in order to reach the position shown in FIG. 9B, the fan moving boss 93 is moved until it hits the stopper 94. To move to the position shown in FIG. 9A, the stopper 94 is moved until it comes into contact with a stopper (not shown in the drawing) on the opposite side of the stopper 94.

  The printed matter partially held by the fan 91 of the delivery fan 90 is discharged from the delivery fan 90 by engaging with the engaging member while the delivery fan 90 is rotating once.

  FIG. 10 is an explanatory diagram showing the positional relationship between the fan 91 of the delivery fan 90 and the engaging member 95. As shown in the figure, the engaging member 95 is disposed so as to be able to enter between the fans 91, and the printed material is discharged from the delivery fan 90 by engaging with the printed material supported by the fans 91. For this reason, if the position of the fan 91 is adjusted as described with reference to FIG. 9, the position of the engaging member 95 needs to be adjusted accordingly.

  Therefore, in this embodiment, the engagement member 95 on the drive side of the folding portion D can be moved along the engagement member support shaft 96, and the position thereof can be adjusted. Specifically, a fixed lever 97 is provided as a position adjusting mechanism, and by loosening the fixed lever 97, the engagement member 95 on the drive side of the folding portion D can be moved, and a predetermined position corresponding to the position of the fan 91 is obtained. Then, the fixing lever 97 is tightened to fix it in the predetermined position. That is, when the paper to be used has a minimum width (1360 mm) (in the case of FIG. 9A), the position indicated by a broken line in FIG. 10 is used, and in the other cases (in the case of FIG. 9B), the position indicated by a solid line. And

  In this embodiment, a stopper is provided so that the engaging member 95 on the drive side of the folding portion D can be easily positioned at the above-described positions. In FIG. 10, the engagement member 95 is abutted against the stopper 98a to be positioned at the solid line position, and is abutted against the stopper 98b to be positioned at the broken line position.

  The printed matter discharged from the delivery fan 90 is dropped onto the delivery belt 110 shown in FIG.

  Here, in this embodiment, as shown in FIG. 9, a guide side plate 120 is provided for guiding both side portions of the printed matter received by the delivery fan part by part. The interval between the guide side plates 120 can be adjusted. Specifically, when the paper to be used has a minimum width (1360 mm), the distance between the guide side plates 120 is narrowed as the position shown in FIG. 9A, and the guide is used as the position shown in FIG. 9B otherwise. The interval between the side plates 120 is increased. Although a position adjustment mechanism for adjusting the interval between the guide side plates 120 is not shown, a known mechanism such as an operation handle can be appropriately employed.

  As described above, according to the present invention, it is possible to cope with a change in the width of the paper to be used by providing a position adjustment mechanism for adjusting the position of the member in contact with the paper in response to the change in the width of the paper to be used. Thus, a plurality of paper with different widths can be processed with a single rotary press.

  If the center of each of the two divided papers cannot be aligned with the center of the former, the traveling direction of the two sheets of paper can be shifted horizontally by combining multiple turn bars (inclined bars) on the rail frame. The center of each paper can be aligned with the center of the former. Of course, since one page width of the paper folded by the former is narrow, each mechanism of the folding portion needs to be adjusted to this paper width.

  In the above embodiment, the rotary press including the rail frame portion C has been described. However, the rail frame portion C is not an essential configuration, and the paper may be conveyed from the printing portion to the folding portion.

  In the embodiment, each position adjustment mechanism is individually operated. However, the position adjustment by each position adjustment mechanism responds to an input of a change in the width of the paper to be used by using a known control mechanism. Can be executed automatically.

  The present invention is not limited to newspaper printing, but can be used for printing various printed materials such as booklets and magazines.
