Description

[0001]
BACKGROUND OF THE INVENTION
  The present invention is provided in a printing machine such as a rotary press, and a bundle of printing papers printed by this printing machine.The present invention relates to a delivery device for a bundle of printed papers that is left as it is or folded and delivered to the next process.
[0002]
[Prior art]
  In general, printing paper printed by a printing machine such as a rotary press is bundled and packaged and delivered to a predetermined delivery destination. As an example of such printing paper, FIG. 6 shows a procedure from a rotary press to shipping in newspaper.
  The newspaper printed in the printing press S1 of the rotary press is fed into the counter stacker CS through a newspaper carrier. In this counter stacker CS, the number of newspapers is counted in the counting division step S2, and a bundle of newspapers called a batch is created in the next small bundle creating step S3 based on the counting result. The batch created in the small bundle creating step S3 is transferred to the rotating basket in the large bundle creating step S4, where the batches are alternately reversed and overlapped to form a large bundle of newspaper bundles called a stack. Created.
[0003]
  The stack is sent out of the counter stacker CS through the sending step S5 and delivered to the underlaying step S6. In this underlaying step S6, in order to prevent the newspaper in the lowermost layer of the stack sent out from the counter stacker CS from being soiled during conveyance, a patron paper-like underlaying paper is placed under the stack, and the next step is loading the address paper. Delivered to step S7.
  In this address sheet loading step S7, an address sheet preprinted with a stack destination, number of copies, newspaper company name, barcode, etc. is attached to the stack.
  The stack to which the address paper is attached is a track gate which is packed and bound in the packaging and binding process S8, and a predetermined delivery truck stands by on the basis of the shipping destination information read from the address paper in the address reading process S9. It is conveyed to a certain shipping process S10.
[0004]
  By the way, in the dispatch of newspapers, the number of newspaper copies is adjusted according to the shipping destination, but depending on the shipping destination, not only a large number of stacks but also a small number of newspaper bundles called fractions may be shipped. is there. Further, it is necessary to wrap and bind such a small number of newspaper bundles with an address sheet.
  However, such a small number of newspaper bundles has a problem that the conveyance behavior becomes unstable in current packaging machines and binding machines that require a certain level of newspaper strength during conveyance. For this reason, the underlay used in the underlay portion is replaced with, for example, a corrugated cardboard having strength, or the strength of the newspaper bundle is improved by manually folding the fractional newspaper bundle into eight. Currently.
[0005]
  However, manual folding has a problem that the working efficiency is remarkably poor and the work burden on the worker is large. Further, since the eight-folding device is large, there is no space for arranging the eight-folding device between the current counter stacker CS and the address sheet mounting step S7, and it is placed after the address sheet mounting step S7. Is the current situation.
  However, when folding in eight, it is extremely difficult to fold the address sheet supplied earlier so that it is located at a predetermined position of the folded newspaper bundle. The address sheet may be once taken out from the newspaper bundle, and the address sheet may be mounted again at a predetermined position of the newspaper bundle after the eight-fold operation is completed. However, there is a problem that the configuration of the apparatus becomes extremely complicated and expensive. In addition, when the newspaper bundle is carried into the eight-folding apparatus and when the newspaper bundle is sent out from the eight-folding apparatus, there is also a problem that the address sheet is easily displaced from the predetermined position of the folded newspaper sheet.
[0006]
  Furthermore, in the above-described conventional newspaper route, the distance between the counter stacker and the eight-folding device is long, and the information sorted by the counter stacker is directly used as a criterion for determining whether the newspaper bundle should be folded in eight. There is a problem that it is difficult to use. Therefore, the height of the newspaper bundle carrying the address paper is detected to determine whether or not to fold it in eight. The height of the newspaper bundle is detected by, for example, a beam sensor or an air sensor from the top or side of the newspaper bundle.
  However, since detection by these sensors is performed while moving on the conveyor when being sent out from the counter stacker, there is a problem that height detection becomes unstable. Also, the height detection becomes unstable due to the amount of air contained in the newspaper bundle, the curl of the newspaper on the top, the number of pages per piece of newspaper, the quality of the newspaper, the ink and moisture content, etc. There is.
[0007]
[Problems to be solved by the invention]
  The present invention has been made in view of the above problems,Judgment whether to fold the printing paper bundle according to the number of pages of the printing paper bundle, and if it is judged not to be folded, it is passed to the next process as it is, and if it is judged to be folded, the printing paper can be folded and delivered to the next process An object is to provide a bundle delivery device.
  Also, when folding is required,Printing paper bundles can be folded automatically and can be placed at any position in the process with a compact structure.Delivery deviceProvided, particularly in newspaper printing, can be provided before the address loading step, preferably immediately after the counter stacker, and has a compact configuration that can stably load the address at a predetermined position after folding in eight. bundleThe purpose is to provide a delivery device.

The direction perpendicular to the Z-axis and the Y-axis) is “left and right”.
[0020]
  FIG. 1 illustrates the present invention.Delivery deviceFIG. 2 is a perspective view of an eight-fold device.
  The eight folding device 100 is provided between the rotating basket 200 of the counter stacker CS and the address paper mounting device 400 of the address paper mounting unit. That is, as shown in FIG. 1, the eight-fold device 100 is provided between the counter stacker CS and the address sheet mounting step S7 (address sheet mounting device 400) among the processes from the printing step S1 to the shipping step S10. That is why.
  Of the newsprint bundles created by the counter stacker CS, those that need to be folded in eight are delivered to the eight-folding device 100, and are folded into eight by the eight-folding device 100, and then addressed by a conveyor or the like. It is sent to the paper loading device 400. In addition, for those that do not need to be folded in half, a newspaper bundle is placed on the underlay 351 supplied from the underlay device 350 as in the past.
[0021]
  As shown in FIG. 1, the eight-fold device 100 is arranged below the counter stacker CS. The eight-fold device 100 is disposed below the counter stacker CS so as to be able to be taken in and out of the counter stacker CS, and is disposed below the rotating basket 200 so as to be tiltable up and down on the base 101. A table 110 for receiving and placing the newspaper bundle P supplied from the hopper, a hopper 130 which is attached to the base 101 and into which the newspaper bundle P is inserted when the table 110 is tilted, and a predetermined number of the newspaper bundle P in the hopper 130. A folding plate 120 that pushes and folds the portion, a newspaper paper bundle P that is folded by the folding plate 120, a driving belt portion 150 that delivers the newspaper paper bundle P to the next process in a state where the newspaper paper bundle P is pressurized from both sides, and the driving belt The hopper 13 is provided between the portion 150 and the hopper 130 and is bent by the folding plate 120. And a guide portion 140 for guiding to a newspaper bundle P drive belt 150 extruded from.
[0022]
  The base 101 may form a space below the counter stacker CS and may be disposed in the space. For example, in the ED-10 type counter stacker manufactured by Gos Graphic Systems Japan, the base 101 is below the counter stacker CS. It can be arranged using the space that originally exists.
  In addition, by making the base 101 movable, it is possible to install the eight-fold device 100 at an arbitrary position, not just below the counter stacker CS.
  Hereinafter, the details of the above-described parts will be described with reference to the perspective view of FIG.
[0023]
[table]
  A table 110 which is a mounting table is attached to the main body of the counter stacker CS above the base 101 (see FIG. 1) of the eight-fold device 100 via a rotation shaft 111 parallel to the X axis so as to be tiltable. . That is, support portions 114 and 114 are provided on the left and right sides of the table 110, and the rotation shaft 111 is provided through the support portions 114 and 114. The support portions 114 and 114 and the rotating shaft 111 can be rotated together by a key or the like, and both ends of the rotating shaft 111 are rotatably supported by bearings (not shown) provided on the main body.
  Further, an arm 112 is provided at an intermediate position between the support portions 114 and 114. One end of the arm 112 is attached to the rotating shaft 111 by a key or welding or the like, and can be rotated together with the rotating shaft 111. The arm 112 is not limited to the rotating shaft 111 and may be fixed to the lower surface of the table 110.
[0024]
  The other end of the arm 112 is connected to the tip of a telescopic piston rod C1a of a cylinder C1 that is swingably attached to the main body. Accordingly, when the piston rod C1a is retracted by driving the cylinder C1, the arm 112 swings in the clockwise direction in the drawing, and the table 110 is tilted together with the rotating shaft 111 to a position inclined by a predetermined angle α from the horizontal position. To do. The upper surface of the table 110 on which the newspaper bundle P is placed is smooth so that the newspaper bundle P can be slid down from the table 110 as a lump when the restriction by the stopper 110 described below is released. It is preferably finished. For example, the upper surface of the table may be plated to reduce the coefficient of friction with the newspaper bundle P so that the newspaper bundle P is bundled and dropped onto the hopper 130.
  In the main body of the counter stacker CS, a cylinder C4 for feeding the newspaper bundle P from the horizontal table 110 is disposed above the table 110. When the cylinder C4 is driven, the piston rod C4a is retracted, and a push plate 117 attached to the tip of the piston rod C4a moves forward in the direction of the arrow in the drawing to push out the newspaper bundle P from the table 110.
[0025]
[Stopper]
  At the front end of the table 110, there is provided a stopper 115 that can be protruded and projected from the upper surface of the table 110. The stopper 115 aligns the paper ends of the newspaper bundle P on the table 110 and protrudes from the upper surface of the table 110 while the table 110 tilts from the horizontal position to the position of the predetermined angle α, so that the newspaper bundle P becomes the table 110. This is to prevent it from falling off. The stopper 115 is formed from a plate-like member having a width dimension substantially equal to the width dimension of the newspaper bundle P. The height of the stopper 115 protruding from the table 110 is at least eightfold so that the newspaper bundle P placed on the table 110 does not fall over the stopper 115 during the tilting of the table 110. It has a height greater than the height dimension of the newspaper bundle P to be made.
[0026]
  The stopper 115 is connected to an extendable piston rod C2a of one or a plurality of cylinders C2 attached to the lower front side of the table 110. When the piston rod C2a expands and contracts as the cylinder C2 is driven, Invade from the top.
  Although not specifically illustrated, the stopper 115 can be quickly lowered when the table 110 is tilted to the predetermined angle α to release the regulation of the newspaper bundle P, and the newspaper bundle P can be reliably delivered to the hopper 130. As described above, movement is guided by a guide (not shown) provided on the table 110.
[0027]
[controlapparatus]
  Whether the table 110 is tilted and whether the stopper 115 is operated, that is, whether the newspaper bundle P is to be sent to the eight folding device 100 or to the underlay process, which is the next process, is determined by the counter stacker CS. This is performed based on information set in advance as to whether or not to make a newspaper bundle to be folded. This information is based on the number of copies for the building page determined in advance by the newspaper company, and is input to the counter stacker CS before the start of printing as preparation for shipping work.
  When printing is started, an instruction for the number of copies of the newspaper bundle P is transmitted from the address paper loading device 400 as a number of copies signal based on the information of the address paper to be loaded next. In the counter stacker CS, it is determined whether or not the sheet should be folded based on the number of copies signal.
[0028]
  For example, when the information that folding into eight is performed in advance when the total number of pages of the newspaper bundle P is less than 120 pages, the number of newspaper pages carried into the counter stacker CS from the rotary press, and the address The total number of pages of the newspaper bundle P is obtained from the number of copies transmitted from the paper loading device 400. If the total number of pages is 120 or more, it is determined that there is no need to fold the paper into eight, and the newspaper bundle P is sent to the conveyor 300 without tilting the table 110. When the total number of pages is less than 120, it is determined that it is necessary to fold the page into eight, the table 110 is tilted, and the newspaper bundle P is put into the hopper 130.
[0029]
  Note that the total number of newspaper pages for determining whether or not to fold in eight is not limited to the above 120 pages, and can be arbitrarily set by a newspaper company.
  Like thisEmbodimentIn this case, it is determined whether the paper should be folded based on the number of newspaper pages and the number of newspapers that make up the newspaper bundle, not the thickness of the newspaper bundle. There is an advantage that accurate determination can be made without being affected by variations in the amount of ink.
[0030]
[Hopper]
  The hopper 130 is attached to the base 101 in a state where it is slightly tilted back and forth from the vertical axis. The hopper 130 has an inlet 131 for the newspaper bundle P at the upper end, and is formed in a box shape wider than the width of the newspaper bundle P in the left-right direction. An inclined surface 135 as shown in the figure may be formed at the insertion port 131 so that the newspaper bundle P sliding down from the table 110 can be smoothly inserted into the hopper 130.
  The inclination angle β of the hopper 130 with respect to the vertical axis is preferably about 15 degrees. Of course, an angle other than this angle can also be selected. In the hopper 130, when there is a possibility that the newspaper bundle P may be in a so-called crushed state due to impact or its own weight at the time of dropping, the fall speed is reduced or the newspaper bundle P is supported by using a leaf spring, a roller or the like. Thus, these inconveniences can be prevented.
[0031]
  Of the front and rear side walls of the hopper 130, the side wall on the address paper loading step S7 side is the portion where the newspaper paper bundle P in a folded state is folded in eight (Bending part) Is formed in a window-like opening 132. Usually mentioned aboveBending partIs substantially at the center of the newspaper bundle P, the opening 132 is preferably formed at a height corresponding to the center of the newspaper bundle P.
  The opening 132 has at least a width in the left-right direction that is slightly larger than the width in the left-right direction of the newsprint bundle P, and the newsprint bundle P folded by a folding plate 120 described later is pushed out of the hopper 130. As shown in the figure, it has at least a vertical width that is larger than the height of the folded newspaper bundle P.
[0032]
  On the other side wall, a folding plate entrance / exit 133 is formed at a position facing the opening 132, through which a later-described folding plate 120 for folding the newspaper bundle P is entered and exited. The folded plate entrance 133 is formed to have a horizontal width and a vertical width that are approximately equal to the horizontal width and the vertical width of the folded plate 120.
  The position of the folded portion of the newspaper bundle P is delicately determined by the rigidity of the newspaper bundle P caused by the number of newspapers constituting the newspaper bundle P, the thickness of the newspaper, the loading speed from the table 110 to the hopper 130, and the like. Change. It also changes as the size of the newspaper page changes. Therefore, it is preferable that the height of the bottom of the hopper 130 is adjustable so that the relative positions of the opening 132 and the folding plate doorway 133 with respect to the folded portion can be changed with the change in the position of the folded portion. .
  For example, the bottom portion may be formed separately from the main body of the hopper 130, and the bottom portion may be attached to the main body with a bolt through a vertical hole formed in the main body.
[0033]
[Folded plate]
  The folding plate 120 for folding the newspaper bundle P is formed from a plate material having a width dimension substantially the same as the width of the newspaper bundle P. The front end edge 121 is formed in a comb blade shape in this embodiment in order to make the contact area with the newspaper bundle P as small as possible and prevent the newspaper bundle P from being scratched or soiled. A partial enlarged view of the front edge 121 is shown in FIG.
  4A is a partially enlarged plan view of the front end edge 121, and FIG. 4B is a cross-sectional view in the II direction of FIG. 4A.
  As shown in FIG. 4A, the front edge 121 of the comb blade shape is finished in a smooth arc shape at each corner of the blade portion 121a of the comb blade. Further, as shown in FIG. 4B, the entire front end 121b of the front end edge 121 is finished in a smooth arc shape when viewed from the side.
  In this way, by eliminating the corners from the blade portion 121a and the tip 121b, the newspaper bundle P can be folded without scratching or soiling the newspaper bundle P.
[0034]
  The folding plate 120 having the above-described configuration is connected to an extendable piston rod C3a of a cylinder C3 that is swingably attached to the base 101. Then, the folding plate 120 enters and exits the hopper 130 from the folding plate doorway 133 by the expansion and contraction of the piston rod C3a accompanying the driving of the cylinder C3. The folding plate 120 is preferably arranged so as to press the newspaper bundle P from a substantially right angle direction, and although not particularly illustrated, the folding plate 120 is guided so that the folding plate 120 can smoothly move forward and backward. It is preferable to provide a guide to be provided on the base 101 or the hopper 130.
[0035]
  When the newspaper bundle P is inserted into the hopper 130, the folding plate 120 having the above-described configuration is retracted to a position where it does not interfere with the newspaper bundle P to be inserted. Projects from 133 into hopper 130.
  The cylinder C3 may be an air cylinder or a hydraulic cylinder as long as it can generate a pressing force sufficient to push and fold the newsprint bundle P. The pressing force can be adjusted by adjusting the pressure of fluid such as air or oil for driving the cylinder C3.
[0036]
[guide]
  Outside the opening 132, a guide 140 is provided that guides the newspaper bundle P that is bent by the folding plate 120 and pushed out from the opening 132.
  FIG. 3 shows a partial cross-sectional side view for explaining the configuration and operation of the guide portion 140.

  Furthermore, in the above description, the newspaper bundle P can be moved between the position where the newspaper bundle P is delivered to the hopper 130 and the position where the newspaper bundle P is delivered to the conveyor 300 by tilting the table 110. However, the newspaper bundle P may be moved at the above two positions by rotating the table 110 around the vertical axis (Z axis) in a horizontal plane.
[0057]
  Further, in the above-described embodiment, by adjusting the biasing force of the spring 141 of the guide part 140 and adjusting the pressing force of the guide roller 142, the newspaper bundle P pushed out from the opening part 132 has a stable shape. Although it can be folded, folding means other than the guide roller 142 may be provided. For example, the drive belt unit 150 may be used for folding.
  Further, the upper belt and the lower belt constituting the driving belt unit 150 may be any shape as long as they can transport the newspaper bundle P, and for example, a grooved round belt, a spring wire, or the like can be used.
[0058]
  The front edge 121 of the folded plate 120 has been described as being formed in a comb blade shape, but the shape of the front edge 121 is not necessarily formed in a comb blade shape. It is good also as a form formed over.
