Description

  The present invention extracts a bundle of a set of sheets in order from the top from a stack of a plurality of sets of sheets stacked up and down through each process of printing, cutting, and collating, The present invention relates to an apparatus that supplies the bookbinding apparatus and the like one by one.

  As a method of manufacturing a booklet such as a calendar, first, a paper sheet constituting each page of the booklet is manufactured by performing a printing and cutting process on the base paper, and then, the paper sheets are continuously arranged in the page order. Further, as shown in FIG. 7, a stack 30 is formed by stacking a number of paper sheets 31 in the vertical direction with the direction and the position of each side aligned, and the binding margin side of the stack 30 After the glue is applied to the entire side surface 30a of the paper and the glue is dried and solidified, a bundle of sheets 31 (sheet bundle 32) constituting one booklet is sequentially extracted from the stack 30 from the top. Then, there is a method of supplying one set at a time to an apparatus (bookbinding apparatus or the like) that executes the next process.

  In this method, the application of the glue to the side 30a on the binding margin side of the stack 30 is performed for the purpose of transporting the sheet bundle 32 extracted from the stack 30 to the next process in a bundled state. However, when glue is applied as it is to the entire side surface 30a on the binding margin side of the stack 30, the lowermost paper sheet 31 (the paper sheet 31 constituting the final page) in each sheet bundle 32 and the lower side thereof Adhesion is also performed with the uppermost paper sheet 31 (the paper sheet 31 constituting the first page) in the next stacked sheet bundle 32. For this reason, when the sheet bundle 32 is to be extracted from the stack 30 one by one, a process of peeling off the adhesion with the next sheet bundle 32 positioned at the lower stage is required, which hinders the smoothness of the work. It becomes a factor.

  Accordingly, only the uppermost paper sheet 31 in each paper sheet bundle 32 among the paper sheets 31 is predetermined on the upper surface (printing display surface) along the binding margin side edge portion 33a using ink having a property of repelling glue. Measures have been taken to perform a special band-shaped print (print the separation band 34). In this case, the paper sheet 31 on which the separation band 34 is printed and the paper sheet 31 stacked on the paper sheet 31 (the lowermost paper sheet 31 in the paper sheet bundle 32 thereon) are the side surfaces on the binding margin side of the stack 30. Bonding with the glue applied to 30a can be preferably avoided, and the sheet bundle 32 can be extracted smoothly from the stack 30.

JP 2000-351288 A

  When the separation band 34 is printed on the uppermost sheet 31 in each sheet bundle 32 and then glue is applied to the side 30a on the binding margin side of the stack 30 to bond the sheets 31, the separation Compared with the case where the belt 34 is not printed, the sheet bundle 32 can be extracted more smoothly. However, the condition of each sheet 31 constituting the stack 30 is not necessarily uniform, and this extraction operation is performed by a machine. It is very difficult to automatically execute it by a typical means (to realize an apparatus that automatically executes the extraction work). For this reason, conventionally, the extraction of the sheet bundle 32 from the stack 30 has been performed manually.

  Specifically, for example, when 50 sheets of calendars are stacked on a horizontal table to form a stack, the binding margin side edge of the uppermost sheet is not necessarily a horizontal straight line. However, there is often a difference in height or distortion between the left and right ends, or between the ends and the middle. When such a height difference or distortion occurs, it becomes difficult to accurately extract a bundle of paper sheets for one set constituting a booklet in an apparatus that automatically performs an extraction operation, As a result, there is a problem that defective products such as missing pages and irregular pages frequently occur.

  In addition, as a continuous supply device for a bundle of paper sheets that can extract a bundle of a set of paper sheets 31 from the stack 30, the paper sheets 31 are sucked and lifted one by one by an adsorption unit in order from the top of the stack 30, By counting one by one on a rotating pin that rotates in a predetermined direction, the position of the last page of the sheet bundle 32 to be extracted is grasped, and a separator is inserted between the sheet bundle 32 of the next stage. Finally, there is known an apparatus configured to sandwich the uppermost sheet bundle 32 and extract it from the stack 30. However, this apparatus requires a considerable time to extract one sheet bundle 32. In other words, compared with the case where it is executed manually by a skilled person, it cannot show superiority in terms of time required, and there is a problem in the accuracy (reliability) of extraction, There is a problem with missing pages There is a problem in that.

  The present invention is intended to solve such a problem of the prior art, and a bundle of sheets capable of extracting a set of bundles of sheets from a stack at a high speed and with extremely high accuracy. An object of the present invention is to provide a continuous supply apparatus.

  The continuous supply device for a bundle of paper sheets according to the present invention extracts a bundle of paper sheets for a set from the stack formed by stacking up and down printed paper sheets for a number of books, and proceeds to the next process. A device that continuously feeds one set at a time, and can be moved up and down to regulate the movement of paper sheets other than the stage on which the stack is placed and the bundle of paper sheets for one set at the top of the stack Stopper, a liftable positioning elevator that sets the extraction stopper at an appropriate height position, and a push that pushes a bundle of sheets at the top of the stack horizontally to extract it from the stack And a transfer clamp that clamps and pulls a bundle of sheets pushed out by the pusher and moves the region from the region above the stack to the region outside the stack. ,stack It descends until it touches the upper surface of the uppermost paper sheet. At that time, the upper edge of the upper surface of the sheet is lower than the height position of the upper surface of the paper sheet by the thickness dimension of the bundle of sheets. The extraction stopper is positioned so that the position of the extraction stopper is positioned, and the extraction stopper is positioned every time a bundle of paper sheets is extracted from the stack and transferred. It is characterized by being.

  One extraction stopper is arranged along each of the left and right ends of the side of the stacking margin side of the stack, and one positioning elevator is arranged above each extraction stopper. preferable. The positioning elevator is composed of a block having a horizontal bottom surface and an adjuster pin that can adjust the amount of protrusion downward from the bottom surface of the block. By adjusting the amount of protrusion of the adjuster pin, the extraction stopper It is preferable that the dimension from the upper end of the positioning elevator to the bottom surface of the block of the positioning elevator can be matched with the thickness dimension of a bundle of paper sheets to be extracted.

  Further, the pusher is constituted by a flap and a block, and the block abuts on the free side edge of a set of paper bundles located at the top of the stack and pushes the paper bundles vertically. And the vertical dimension of the vertical plane matches the thickness dimension of the bundle of paper sheets to be extracted, and the flap extends from the upper edge of the vertical plane to the binding margin side of the paper sheet. It is preferable that it is comprised so that it may protrude toward.

  In addition, it has an air nozzle that injects air toward the boundary between a bundle of a set of paper sheets positioned at the top of the stack and a bundle of sheets of a second set of paper, and air is injected from the air nozzle. It is preferable to have a shutter that abuts against the upper surface of the uppermost paper sheet of the stack and presses it from above and prevents the air jetted from the air nozzle and flowing in between the paper sheets.

  The sheet bundle continuous supply device of the present invention can extract and transfer a set of sheet bundles from the stack in order from the top, and can continuously supply the bundle to a bookbinding device or the like. In addition, since the positioning of the extraction stopper is accurately performed with respect to the height position of the upper surface of the uppermost sheet bundle to be extracted for each process, the uppermost sheet bundle of the stack is positioned. Even if there is a difference in height or distortion at the binding margin side edge, it is possible to accurately extract a bundle of paper sheets constituting a set of booklets without excess or deficiency. The frequency with which such defective products are generated can be extremely reduced.

  Also, in this continuous sheet bundle supply device, when an air nozzle that injects air toward the boundary between the uppermost sheet bundle of the stack and the second sheet bundle is attached, When extruding the sheet bundle, the frictional resistance with the second stage sheet bundle can be reduced, and the extraction of the sheet bundle can be executed more smoothly. Furthermore, when a shutter that prevents the flow of air flowing between the sheets is attached, the air flowing between the sheets reaches the binding margin side edge and is applied to the binding margin side surface of the stack. It is possible to suitably avoid the situation where the adhesive between the paper sheets due to the glue is peeled off.

  Embodiments of the “sheet bundle continuous supply device” of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a diagram showing the structure of the main part of a continuous supply apparatus 1 for sheet bundles according to the present invention, and FIGS. 2 to 6 show the operation modes of the continuous supply apparatus 1 for sheet bundles shown in FIG. It is explanatory drawing of the reference position before operation | movement, the time of positioning, the time of extrusion, and the time of transfer). As shown in the figure, the continuous supply device 1 for a sheet bundle includes a stage 2, a guide 3, an extraction stopper 4, a positioning elevator 5, a shutter 6, a pusher 7, an air nozzle 8 (see FIG. 1 above), and And a transfer clamp 9 (see FIG. 2).

  The stage 2 is for placing a stack 30 in which a large number of paper sheets 31 are stacked, and is configured to be movable up and down. In addition, on the stage 2, a large number of paper sheets 31 manufactured by performing a printing and cutting process on the base paper are collated so as to be continuous in the order of the pages, and the direction and the position of each side are aligned. The stack 30 is formed by stacking up and down, and as shown in FIG. 7, each of the first pages is formed in a bundle (sheet bundle 32) of sheets 31 (one set) constituting one booklet. Only the uppermost paper sheet 31 to be printed is printed with the separation band 34 along the binding margin side edge portion 33a on the upper surface, and paste is applied to the entire binding margin side surface 30a and solidified. To do.

  The guide 3 is for holding the placed stack 30 at an appropriate position on the stage 2, and is arranged at a position for pressing the side 30a on the binding margin side of the stack 30, as shown in FIG. In addition, it is also arranged at a position where both side surfaces of the stack 30 are pressed (not shown).

  The extraction stopper 4 is for restricting the movement of the paper sheet bundle 32 other than the paper sheet bundle 32 positioned at the uppermost stage of the stack 30 (that is, the second or lower stage from the top), and is shown in FIG. As described above, one (a total of two) is arranged along each of the left and right end portions of the side 30a of the binding margin side of the stack 30, both of which can be moved up and down by an actuator not shown, and any It is comprised so that the state stopped at the position of can be maintained. As shown in FIG. 2, the upper surface 4a of each extraction stopper 4 is formed with a claw 4b protruding upward.

  When the positioning elevator 5 extracts the uppermost sheet bundle 32 from the stack 30, the positioning stopper 5 allows the extraction stopper 4 to move to an appropriate height position (the uppermost sheet bundle 32 is moved, and two stages from the top. This is for setting at a position where the movement of the sheet bundle 32 below the eyes can be regulated. As shown in FIG. 2, the positioning elevator 5 includes a block 5a having a horizontal bottom surface, and an adjuster pin 5b that penetrates the block 5a up and down and can accurately adjust the amount of protrusion downward from the bottom surface. As shown in FIG. 1, one is disposed above each extraction stopper 4, and each is configured to be movable up and down by an actuator (not shown).

  The pusher 7 pushes out the sheet bundle 32 positioned at the uppermost stage of the stack 30 in the horizontal direction (extension direction on the binding margin side of the sheets 31, leftward in FIGS. 2 to 6), and extracts from the stack 30. For this purpose, as shown in FIG. 2, the flap 7a and the block 7b are used. The block 7b has a vertical surface 7c that abuts against a free side edge 33b of the paper sheet 31 (an edge of the paper sheet 31 opposite to the binding margin side) and pushes the paper sheet bundle 32, and the flap 7a. Is configured to project forward from the upper edge of the vertical surface 7c (to the binding margin side of the paper sheet 31, left side in FIG. 2). The height dimension of the vertical surface 7c (the dimension from the lower surface of the block 7b to the lower surface of the flap 7a) is almost the same as the thickness dimension of one paper sheet bundle 32 (a bundle of paper sheets 31 for one booklet). Match. The pusher 7 is supported so as to be movable in the vertical direction together with an actuator (not shown) for pushing the pusher 7 in the horizontal direction, and is urged downward by gravity.

  The air nozzle 8 is for reducing the frictional resistance with the second-stage paper bundle 32 when the uppermost paper-sheet bundle 32 is pushed out by the pusher 7 so as to realize smooth extrusion. As shown in FIG. 4, the stack 30 is disposed in the vicinity of the free side surface 30b (on the left and right sides of the two pushers 7) and in the vicinity of the intermediate positions on both sides of the stack 30. Air is jetted at an appropriate timing toward the boundary between the sheet bundle 32 and the second-stage sheet bundle 32.

  The shutter 6 is configured such that the air jetted from the air nozzle 8 passes between the paper sheets 31 stacked one above the other and escapes from the binding margin side edge portion 33a, and the binding margin side surface 30a of the stack 30. In order to prevent the paper sheets 31 from being peeled off due to the glue applied to the paper sheet, the paper sheet 31 is positioned above the stack 30 and closer to the binding margin side than the intermediate position in the vertical direction of the paper sheets 31. It is arranged so that it can be moved up and down from this position by an actuator (not shown).

  The transfer clamp 9 sandwiches the binding margin side portion of the uppermost sheet bundle 32 of the stack 30 pushed out by the pusher 7 in the extending direction on the binding margin side of the paper sheet 31, and further pulls in the same direction. 2 for completely moving from the region on the stack 30 to the region outside the stack 30. As shown in FIG. 2, the upper nail 9a and the lower nail 9b can be freely opened and closed, and the paper sheets 31 are bound. It is configured to be movable in the extension direction on the substitute side and in the opposite direction.

  Here, the operation | movement aspect of the continuous supply apparatus 1 of the paper sheet bundle of this embodiment is demonstrated. Each component (the transfer clamp 9, the extraction stopper 4, the positioning elevator 5, the shutter 6, the pusher 7 and the like) of the continuous supply device 1 of the sheet bundle is set at the reference position shown in FIG. 2 before the operation. It is localized.

  More specifically, the transfer clamp 9 has the upper nail 9a and the lower nail 9b opened (expanded state), and the uppermost sheet bundle 32 of the stack 30 is on the binding margin side of the sheet 31. When pushed out in the extending direction, the binding margin side portion of the sheet bundle 32 can be received between the upper nail 9a and the lower nail 9b (a height corresponding to the height of the uppermost sheet bundle 32). The extraction stopper 4 is localized at positions along the left and right end portions of the side surface 30a on the binding margin side of the stack 30.

  Further, the positioning elevator 5 and the shutter 6 are positioned at a predetermined distance above the stack 30, and the pusher 7 has a lower surface of the flap 7 a on the uppermost sheet 31 of the stack 30. It is placed on the side edge portion 33 b and the vertical surface 7 c is positioned at a position facing the free side surface 30 b of the stack 30. The amount of protrusion of the adjuster pin 5b in the positioning elevator 5 (the amount of protrusion downward from the bottom surface of the block 5a) is the extraction stopper when the lower end of the adjuster pin 5b is in contact with the upper surface 4a of the extraction stopper 4. 4 is the thickness of the upper end of the claw 4b projecting upward from the upper surface 4a of the sheet 4 and the bottom surface of the block 5a of the positioning elevator 5 is the thickness of one sheet bundle 32 (the bundle of sheets 31 of one booklet). Adjustment is made so as to match the dimensions (match within an error range equal to or less than the thickness dimension of one sheet of paper 31).

  When the sheet bundle continuous supply device 1 executes the operation of extracting the sheet bundle 32, the extraction stopper 4 is first positioned. Specifically, as shown in FIG. 3, the extraction stopper 4 first rises. Then, when the upper surface 4a of the extraction stopper 4 comes into contact with the adjuster pin 5b of the positioning elevator 5 stopped above the extraction stopper 4, the upward movement of the extraction stopper 4 stops, and this time the positioning elevator 5 starts to descend. Then, the extraction stopper 4 is lowered while being pushed down.

  When the positioning elevator 5 descends while pushing down the extraction stopper 4 and the bottom surface of the block 5a of the positioning elevator 5 comes into contact with the top surface of the uppermost sheet 31 of the stack 30, as shown in FIG. The elevator 5 stops descending. At this time, the amount of downward protrusion of the adjuster pin 5b in the positioning elevator 5 is such that the size of the gap between the upper end of the claw 4b protruding upward from the upper surface 4a of the extraction stopper 4 and the bottom surface of the block 5a of the positioning elevator 5 is determined. Since the thickness of the sheet bundle 32 is adjusted so as to coincide with the thickness dimension of one sheet bundle 32, the upper end of the claw 4b is accurately positioned from the upper surface of the uppermost sheet 31 of the stack 30. The sheet is positioned at a position lower by the thickness of one sheet bundle 32, that is, at the same height as the upper surface of the uppermost sheet 31 in the second sheet bundle 32 of the stack 30. As a result, the extraction stopper 4 allows the movement of the uppermost sheet bundle 32 and restricts the movement of the second and subsequent sheet bundles 32 from the top.

  The positioning elevator 5 comes into contact with the upper surface of the uppermost sheet 31 of the stack 30, stops descending, and immediately completes the positioning of the extraction stopper 4, and returns to the reference position shown in FIG. At the same time or before and after this, as shown in FIG. 4, the shutter 6 descends, abuts against the upper surface of the uppermost paper sheet 31 of the stack 30, and presses the paper sheet 31 from above. It is provided for the injection of air from the air nozzle 8 (see FIG. 1).

  In this state, air is jetted from the six air nozzles 8 shown in FIG. 1 toward the boundary between the uppermost sheet bundle 32 and the second sheet bundle 32. If it does so, air will flow in between the paper sheets 31 piled up and down, and the frictional resistance between the paper sheets 31 will be reduced. The air flowing between the paper sheets 31 is prevented from advancing between the paper sheets 31 by the shutter 6 that presses the paper sheets 31 from above, and the air that has flowed in reaches the binding margin side edge portion 33a and stacks. A situation in which the adhesion between the paper sheets 31 due to the glue applied to the side surface 30a on the binding margin side 30 is peeled off is avoided.

  When the frictional resistance between the paper sheets 31 is reduced as described above, the pusher 7 moves from the reference position toward the binding margin side as shown in FIG. 32 is pushed out to the binding margin side. At this time, the vertical surface 7c of the pusher 7 that contacts the free side edge portion 33b of the paper sheet bundle 32 coincides with the thickness dimension of one paper sheet bundle 32, and the extraction stopper 4 is As a result of positioning by the positioning elevator 5, the stack 30 is configured because the uppermost sheet bundle 32 is allowed to move and the movement of the second and lower sheet bundles 32 from the top can be regulated. Only a bundle of paper sheets 31 (paper sheet bundle 32) for one booklet from a large number of paper sheets 31 is pushed out accurately from the uppermost position in the extending direction on the binding margin side.

  The shutter 6 that has been in contact with the upper surface of the uppermost paper sheet 31 of the stack 30 and pressed the paper sheet 31 from above starts the movement of the pusher 7, and the uppermost sheet bundle 32 moves. Ascending just before starting, the paper sheet 31 or the paper sheet bundle 32 is released. In addition, the air nozzle 8 that ejects air toward the boundary between the uppermost sheet bundle 32 and the second sheet bundle 32 ends the ejection when the shutter 6 starts to rise or immediately after that. Even after the air injection by the air nozzle 8 is completed, the air flowing in between the paper sheets 31 remains, so that the frictional resistance between the paper sheets 31 is still reduced. The uppermost sheet bundle 32 can be pushed out smoothly.

  When the uppermost sheet bundle 32 is pushed out in the extending direction on the binding margin side by the pusher 7, the binding margin side portion is localized in the expanded state in the vicinity of the same direction as shown in FIG. The transfer clamp 9 enters between the upper and lower claws 9a and 9b. At this point, the pusher 7 stops moving and retreats toward the original position as shown in FIG. The pusher 7 slides on the second-stage sheet bundle 32 when moving backward, but the pusher 7 (and its actuator) can be moved in the vertical direction. Since the vertical surface 7c passes through the position of the free side edge portion 33b of the second-stage paper bundle 32, it is supported and urged downward by gravity. The sheet is lowered (dropped) by the thickness dimension, and the lower surface of the flap 7a is placed on the free side edge portion 33b of the second-stage sheet bundle 32.

  On the other hand, when the binding margin portion of the uppermost sheet bundle 32 enters the transfer clamp 9, the upper claw 9 a and the lower claw 9 b are closed, and the sheet bundle 32 is clamped by the transfer clamp 9. As shown in FIG. 6, the transfer clamp 9 moves in this state in the extending direction on the binding margin side of the paper sheet 31, and the sandwiched paper sheet bundle 32 is completely transferred from the area on the stack 30 to the outer area. Move.

  When the transfer clamp 9 pulls the paper sheet bundle 32 to a predetermined position and completes the transfer, the upper claw 9a and the lower claw 9b are expanded, and the paper sheet bundle 32 that has been sandwiched is opened, to a bookbinding apparatus or the like. Supply. Thereafter, the transfer clamp 9 moves in the opposite direction and returns to the original position (reference position shown in FIG. 2). At the same time as or before and after the movement of the transfer clamp 9, the stage 2 is raised by the thickness dimension of one sheet bundle 32, and all the components other than the stage 2 are restored to their original positions. It returns to the state (state shown in FIG. 2).

  The continuous supply apparatus for the sheet bundle according to the present embodiment repeats these series of operations and continuously executes the above operation to raise the bundle of sheets 31 (sheet bundle 32) from the stack 30. Can be extracted and transferred in order, and continuously supplied to a bookbinding apparatus or the like at high speed. In addition, the positioning of the extraction stopper 4 is performed so that the upper surface of the uppermost sheet bundle 32 to be extracted (the most of the stack 30) is extracted every time one process (the process of extracting and transferring one sheet bundle 32). This is a case where there is a difference in height or distortion in the binding margin side edge portion 33a of the uppermost sheet bundle 32 of the stack 30 because it is accurately performed with reference to the height position of the upper surface of the upper sheet 31). However, it is possible to accurately extract a bundle of paper sheets constituting one booklet without excess or deficiency, and it is possible to extremely reduce the frequency of occurrence of defective products such as missing pages or irregular pages.
