Description

  The present invention relates to a book having a hinge.

  In a general book, when the page is opened, a portion connecting the upper and lower pages or the left and right pages (hereinafter referred to as a spread portion) is curved.

  On the other hand, a book represented by an album or a photo book is required to be a book having a wide spread property without curving a spread part, from the viewpoint of commercial property that a large number of people may simultaneously view it. A book having a hinge is known as a book represented by such an album or a photo book. Patent Document 1 describes that when forming one page, a gap is formed between an image portion on which an image is formed and a binding margin portion, and the gap is connected by a film hinge. .

JP, 2009-286104, A

  A book composed of pages as described in Patent Document 1 has better spreadability compared to a book composed of pages having no hinge because the hinge made of a film bends flexibly.

  However, according to the study of the present inventors, it has been found that even such a book may not have sufficient spreadability as described below.

FIG. 2 shows a book in which pages of the same size are arranged as usual using pages described in Patent Document 1. As shown in FIG. In FIG. 2 (a), the binding margin portion 50b, a hinge 51 b, and an image portion 50a on which an image is formed, a book 53 which is constructed by arranging a plurality of pages with the rear side in this order shown It is done.

A state in which the page near the center of the book shown in FIG. 2 (a) is opened is shown in FIG. 2 (b). As shown in FIG. 2 (b), the hinge 51b is flexibly bent on the page near the center, and the spreadability is good.

On the other hand, FIG. 2C shows a state in which the page at the end of the book shown in FIG. 2A is opened. In the state in FIG. 2 (c), the hinge 51 b spreads more than necessary, large gap facing portion has occurred. Therefore, there is a problem in the spreadability such that the continuity of the images formed on both sides through the spread portion is reduced. Conversely, in order to enhance the spread of in the state of FIG. 2 (c), for example, shortening the length of the hinge 51 b, this time without the hinge 51 b is function well in the state of FIG. 2 (b), the central The spreadability of the nearby pages is reduced.

  Therefore, the present invention aims to provide a book having a hinge and having a wide spread on the end pages and the center page.

The above problems are solved by the present invention described below. That is, the present invention is a book having a plurality of pages having a binding margin portion, a hinge, and an image portion on which an image is formed in this order from the back side, the binding margin portion of the plurality of pages; When the hinge and the image portion are linearly arranged in each page, and the back side is the lower side, and the opposite side to the back side is the upper side, the position of the end on the image portion side of the hinge is an end The center page is located on the upper side of the page, and the position of the end on the image portion side of the hinge is a mountain shape in the whole book, and the length of the hinge of the center page is The book is characterized in that it is longer than the hinge length of the end page, and the length of the binding margin portion of the central page is the same as the length of the binding margin portion of the end page.

  Hereinafter, the book of the present invention will be described in detail.

  FIG. 1 (a) shows an example of a book of the present invention. The book 53 shown in FIG. 1A is in a closed state, and includes a plurality of pages having a binding margin portion 50b, a hinge 51a, and an image portion 50a on which an image is formed, from the back side. ing. That is, one page has a binding margin portion 50b, a hinge 51a, and an image portion 50a on which an image is formed. The back surface is a surface on the lower side of the book 53 in FIG. 1A, and is a surface on which a cover (back cover) is formed, for example. In FIG. 1A, the binding margin portion, the hinge, and the image portion are linearly arranged for each page.

  The image portion 50a is a portion where an image is formed. Examples of the image portion 50a include plain paper, coated paper having a receptive layer for receiving ink and the like, a film and the like.

  The binding margin portion 50b may be a binding margin, but is preferably formed of the same material as the image portion 50a from the viewpoint of manufacturing. That is, if coated paper is used for the image portion 50a, it is preferable that the binding margin portion 50b also be coated paper. In such a case, although it will be described later, for example, one coated paper can be cut to form the image portion 50a and the binding margin portion 50b.

  The hinge 51a is a portion connecting the binding margin portion 50b and the image portion 50a. The hinge 51a is preferably flexible and is preferably formed of, for example, an adhesive tape. Examples of the pressure-sensitive adhesive tape include a pressure-sensitive adhesive tape constituted of a PET (polyethylene terephthalate) substrate and a pressure-sensitive adhesive layer containing an epoxy-based adhesive. The hinge may be formed by bonding a plurality of such adhesive tapes. For example, one hinge can be formed by overlapping two adhesive tapes so that the adhesive layers face each other. The thickness of the hinge 51a may be appropriately designed in consideration of flexibility and mechanical strength contributing to the spread of the book, but for example, the thickness of the base material is 5 μm to 25 μm, and the thickness of the adhesive layer is 5 μm or more It is preferable to set it as 40 micrometers or less. The thickness of the hinge means the thickness of the hinge in the direction orthogonal to the extension direction of the hinge (arrangement direction when the hinge and the image portion are linearly arranged).

  The hinge 51a may be formed by extending an adhesive tape that covers the surface of the image portion 50a (on the image portion) and the surface of the binding margin portion 50b (on the binding margin portion). At this time, it is preferable that the length 55 of the adhesive tape on the image portion be uniform among a plurality of pages. For example, the length of the adhesive tape on the image portion in each page is preferably within ± 1.0 mm with respect to the average length of the adhesive tape on the image portion in a plurality of pages. By doing this, the visibility of the image formed in the image portion can be made uniform among a plurality of pages. Further, from the viewpoint of production, it is preferable to make the length 56 of the entire adhesive tape uniform among a plurality of pages. For example, the entire length of the adhesive tape in each page is preferably within ± 1.0 mm from the average length.

  As shown in FIG. 1 (a), the present invention is characterized in that the position of the end 54 on the image portion side of the hinge is located on the center page above the end page. In FIG. 1A, the end 54 on the image portion side of the hinge is a portion where the hinge 51a and the image portion 50a are connected. The end 54 on the image portion side of the hinge is located on the upper side of the center page than the end page, and the book 53 as a whole is shaped like a mountain.

  With such a configuration, it is possible to increase the spread on both the end page and the center page. Further, it is easy to set the image position in the image portion 50a to a position to be aligned on all pages.

  In FIG. 1A, by changing the length of the hinge 51a, the position of the end 54 on the image portion side of the hinge is located on the center page above the end page. The length of the binding margin portion 50b is the same for all pages. That is, the length of the hinge 51a on the center page is made longer than the length of the hinge 51a on the end page.

  The length of the hinge 51a is preferably determined in accordance with the thickness of the binding margin portion. It is also preferable to design according to the thickness and the number of image portions. For example, when the image portion is 10 sheets or more and 100 sheets or less and the thickness of one image portion is 0.1 mm or more and 0.5 mm or less, the hinge length of the end page is 0.3 mm or more and 1.0 mm or less Preferably, the hinge length of the central page is 0.5 mm or more and 4.0 mm or less. The length of the page hinge between the end page and the center page is preferably between the length of the end page hinge and the length of the center page hinge. The length of the hinge is the length of the portion connecting the binding margin portion 50b and the image portion 50a, and in the case of FIG. 1A, it is the same as the length between the binding margin portion 50b and the image portion 50a. It is.

  Although FIG. 1A shows a diagram in which the length of the hinge always changes from the end page to the center page for simplification, it is possible to continue the pages having the same length hinge. Good. For example, with respect to the length of the hinge, 0.5 mm from the first to fifth sheets at the end, 1.0 mm from the sixth to tenth sheets, 1.5 mm from the eleventh to fifteenth sheets in the center The tenth to twenty-th sheets are 1.0 mm, and the twenty-first to twenty-fifth sheets are 0.5 mm. From a manufacturing point of view, it is preferable to continue the pages having the same length hinges in this way. The position of the end on the image portion side of the hinge is a mountain-like and step-like shape throughout the entire book. On the other hand, from the viewpoint of further improving the spreadability, it is preferable to make the pages having hinges of the same length not be as continuous as possible.

  The method of binding such a book will be described below.

  FIG. 3A is a diagram for conceptually explaining the processing procedure. First, one print sheet is divided into an image portion 50a on which an image is printed and a binding margin portion 50b serving as a binding margin in bookbinding. When generating a print sheet by the printing apparatus, a margin is also provided together with a desired image in anticipation of a binding margin in advance. Then, the cut sheets are accurately positioned so as to provide a gap having a desired dimension in parallel between the image portion 50a and the binding margin portion 50b. Then, on the gap, the transparent adhesive tape 51a is attached from both sides of the sheet. Thus, a flexible hinge of adhesive tape is formed between the image portion and the binding margin portion. As described below, these processing steps can be performed by an automated apparatus without the hands of the operator.

  FIG. 3B shows a completed state in which a plurality of processed print sheets are bundled and bound. The binding margin portions 50b of the respective sheets are overlapped and fixed inside the cover 52 by a known method such as yarn binding, staple binding, bond consolidation and the like. Each sheet can be bent and opened by a hinge 51a formed of a flexible adhesive tape. Since the hinge made of the adhesive tape is more easily bent than the sheet itself, even if the left and right pages are opened, the spread between the pages becomes flat by 180 °, and so-called lay flat bookbinding is performed.

  Next, details of the sheet processing apparatus that automatically performs the above-described processing steps will be described.

  FIG. 4 shows the appearance of the sheet processing apparatus 1. 11 is a second slide door for the operator to load the print sheet to be processed, 12 is a second slide door for the operator to take out the processed print sheet, and 13 is a second for the operator to supply adhesive tape for processing There are three doors.

The first adhesive tape is attached to the front surface (first surface) of the sheet, and the second adhesive tape is attached to the back surface (second surface) of the sheet. Reference numeral 43 denotes a pressure plate provided on the supply arm 32. When the supply arm 32 is positioned on the processing table 30, the pressing plate 43 presses the end of the sheet from above onto the processing table 30 to make the sheet conform to the plane of the table, thereby correcting the warp of the sheet. It is to do.

  FIG. 15 is a top view conceptually showing the configuration of FIG. In FIG. 15A, the supply tray 31, the processing table 30 (the first stage 33, the second stage 40), and the discharge tray 36 are arranged side by side. The tape supply unit 60 supplies two adhesive tapes. The guide 41 a guides the movement of the processing unit 41 in the left-right direction.

The discharge arm 37 has two arms that support the four suction pads 37c, 37d, 37e and 37f (sucking portions). The supply arm 32 and the discharge arm 37 move integrally by the drive unit 34.

  The sheets stacked on the supply tray 31 are transported one by one onto the processing table 30 by the supply arm 32, the discharge arm 37 and the drive unit 34, and the sheets on the processing table 30 are transported to the discharge tray 36. The sheet transfer unit is configured.

  FIG. 6 shows the detailed configuration of the sheet transfer unit. The sheet supply side supply arm 32 includes a plurality of sub arms and a plurality of suction pads. The supply arm 32 has a first sub arm 32a and a second sub arm 32b, and moves in the directions of arrows A and B. The first sub arm 32a supports the suction pad 32c, and the second sub arm 32b supports the suction pads 32d and 32e. The suction pads 32c, 32d, 32e are connected by a tube to a negative pressure source to hold the surface of the printing sheet by suction. The second sub arm 32 b is structured such that it can be positionally adjusted in the longitudinal direction of the supply arm 32 according to the size of the printing sheet. In addition, each suction pad has a structure that can be adjusted in the longitudinal direction of each sub arm according to the size of the printing sheet to be suctioned.

  On the other hand, the sheet discharge side discharge arm 37 includes a plurality of sub arms and a plurality of suction pads. The discharge arm 37 has a first sub arm 37a and a second sub arm 37b, and moves in the directions of arrows A and B. The first sub arm 37a supports the suction pad 37c, and the second sub arm 37b supports the suction pads 37d and 37e. The suction pads 37c, 37d, and 37e are connected by a tube to a negative pressure source to hold the surface of the printing sheet by suction. The second sub arm 37 b is structured such that it can be adjusted in the longitudinal direction of the supply arm 37 according to the size of the printing sheet. In addition, each suction pad has a structure that can be adjusted in the longitudinal direction of each sub arm according to the size of the printing sheet to be suctioned.

  FIG. 7 is a diagram for explaining the details of the processing table 30. As shown in FIG. The processing table 30 has independent first and second stages 33 and 40. The first stage 33 holds the image portion of the sheet by its holding surface 33a, and the second stage 40 holds by suction the portion which becomes the binding margin of the sheet by its holding surface 40a. The relative positions of the first stage 33 and the second stage 40 can be changed with respect to the direction (direction of arrow J) orthogonal to the direction in which the sheet is cut by the cutter unit. In this apparatus, each of the first stage 33 and the second stage 40 has a mechanism for moving the stage independently in the arrow C direction and the arrow D direction, and the interval between the two can be changed. The first stage 33 may be fixed so that only the second stage can move.

  The inside of the first stage 33 is a negative pressure chamber connected to a negative pressure source. A plurality of holes 33b communicating with the internal negative pressure chamber are formed in the holding surface 33a, and the print sheet is held by suction via the holes 33b. Similarly, the inside of the second stage 40 is a negative pressure chamber connected to a negative pressure source. A plurality of holes 40b communicating with the internal negative pressure chamber are formed in the holding surface 40a, and the print sheet is held by suction via the holes 40b.

  The second stage 40 is provided with a positioning surface 40 c which abuts on a piece of the printing sheet placed on the processing table and performs positioning (alignment of inclination) of the printing sheet. The positioning surface 40c has a flat surface parallel to the direction in which the cutter portion cuts the sheet (arrow K direction). The positioning surface 40c abuts one side of the sheet serving as a binding margin of the sheet placed on the processing table so that the cutter unit pushes in a direction (arrow J direction) orthogonal to the direction of cutting the sheet. The second stage 40 is moved in the direction opposite to the arrow J direction. Thus, the sheet is positioned such that the direction of one side of the sheet is parallel to the direction in which the cutter unit cuts (the direction of the arrow K).

  FIG. 7A shows a state in which the first stage 33 and the second stage 40 are in contact with each other. In this state, the sheet holding surface 33a of the first stage 33 and the sheet (binding margin) holding surface 40a of the second stage 40 are connected to form a continuous flat surface. FIG. 7B shows a state in which the first stage 33 and the second stage 40 are separated.

  The positional relationship of these two stages is the process of positioning the sheet, the process of cutting the sheet by the cutter unit, the process of adjusting the gap between the cut sheets, the process of supplying the tape, the process of sticking the tape through the pressure roller. , Is set to suit each. Details will be described later.

  FIG. 8 shows an internal configuration of the tape supply unit 60 which is a part of the taping unit. The adhesive tape supplied from the first tape supply unit 38 is guided to the processing table by the guide rollers 61a, 61b, 61c, 61d. The adhesive tape supplied from the second tape supply unit 39 is guided to the processing table by the guide rollers 62a, 62b and 62c. The upper and lower adhesive tapes are held by the movable chuck 63 in the vicinity of the leading end of the sheet which has been pulled out, with the adhesive surfaces facing each other. The tape supply unit 60 and the processing unit 41 constitute a taping unit.

  FIG. 9 is a system block diagram of the sheet processing apparatus as viewed from the control system. The control unit 100 includes a CPU 101 that performs control and calculations, a ROM 102 that stores programs, constants, and table data of numerical values, and a RAM 103 that stores temporary data. Furthermore, various drivers for driving various motors, pumps, solenoid valves and the like are provided.

  The control unit 100 is connected to various motors, pumps, solenoid valves, and the like to be controlled. The motor 104 is a drive source for moving the supply arm 32 and the discharge arm 37, and the motor 105 is a drive source for reciprocating the processing unit 41 along the guide 41a. The pressurizing pump 106 is a pump for storing high pressure compressed air for driving various cylinders in a high pressure tank, and for storing negative pressure air serving as a negative pressure source for sheet adsorption in a negative pressure tank. The blower 70 is a fan that blows for sheet separation.

  The solenoid valves 107, 108, 109, 110 and 111 respectively move the first stage 33, move the second stage 40, raise and lower the supply tray 31, raise and lower the supply arm 32 and the discharge arm 37, and extend and retract the supply arm 32.

  The sensors 120 are a plurality of sensors that detect the pressure inside the high pressure tank and the negative pressure tank. The sensor 121 is a sensor that detects the presence or absence of a sheet placed on each of the supply tray 31, the first stage 33, and the discharge tray 36, and a stacked amount. The sensor 122 is a position sensor that detects positions of the supply arm 32 and the discharge arm 37 in the height direction, the supply / discharge direction, and the depth direction. A sensor 123 is a position sensor that detects the position in the processing unit movement direction.

  Next, an operation procedure of each process in the sheet processing apparatus having the above-described configuration will be described. First, a schematic sequence when processing a single print sheet will be described using the flowchart of FIG.

  In step S <b> 1, the uppermost one of the unprocessed printing sheets placed on the supply tray 31 by the operator is picked up by the supply arm 32. In step S2, the print sheet picked up is transferred onto the processing table 30 by the sheet transfer unit. In step S3, the printing sheet placed on the processing table 30 is positioned with its inclination corrected. In step S4, the cutter unit cuts the positioned sheet so as to generate a portion that becomes a binding margin at the time of bookbinding. In step S5, the adhesive tape is supplied from the tape supply unit to the processing table. In step S6, the sheets are positioned so that the gaps between the cut sheets are parallel and have a predetermined size. In step S7, in the taping section, the pressure-sensitive adhesive tape is pressed and attached from both sides of the cut sheets with a pressure roller to bond the sheets together. In step S8, the bonded adhesive tape is cut in the vicinity of both ends of the sheet. In step 9, the processed sheet is transferred from the processing table 30 to the discharge tray by the sheet transfer unit. At this time, when the unprocessed sheet still remains, at the same time as discharging, the next sheet is transferred from the supply tray 31 to the processing table 30. The above operation is repeated until all printing sheets placed on the supply tray 31 have been processed.

  Hereafter, the further detail of each process is demonstrated. FIG. 11 is a diagram showing a state of transition in which the positional relationship between two stages changes in accordance with the processing operation in the processing table. This is a cross-sectional view of the first stage 33 and the second stage 40 as viewed in the direction of arrow K in FIG.

  FIG. 11A shows the positional relationship between the first stage 33 and the second stage 40 when the sheet 50 is placed on the processing table from the supply tray. A small gap is provided between the two stages. The supplied sheet 50 is placed so as to straddle the holding surface 33 a of the first stage 33 and the holding surface 40 a of the second stage. The sheet 50 is placed such that a slight gap is opened between the end which is one side of the sheet and the positioning surface 40 c provided on the second stage 40. In this state, neither the first stage 33 nor the second stage 40 generates an adsorption force due to negative pressure, and the sheet is merely placed on each holding surface without adsorption.

Next, as shown in FIG. 11B, the second stage 40 is moved in a direction (arrow E direction) approaching the stationary first stage 33. One side of the sheet 50 is pushed by the positioning surface 40c, and even if the sheet is inclined, the inclination is corrected and positioning is performed. (Step S3 in FIG. 10)
Subsequently, the pressing plate 43 is lowered to a position indicated by a dashed dotted line in FIG. 11B, and the end of the sheet 50 is pressed against the holding surface 33a and the holding surface 40a. In the pressed state, negative pressure is supplied to the negative pressure chambers of the first stage 33 and the second stage 40, and the sheet 50 is adsorbed by the holding surface 33a and the holding surface 40a. Since the sheet is pressed with no gap by the pressing plate and the sheet is not warped and adsorption is started, the sheet can be reliably adsorbed and held in a short time.

Subsequently, while the negative pressure chamber of the first stage 33 is maintained at a negative pressure, only the negative pressure chamber of the second stage 40 is communicated with the atmosphere to eliminate the negative pressure. The sheet 50 is attracted and held only by the holding surface 33a. In that state, the second stage 40 is moved in the arrow F direction while the first stage 33 is stationary. When the distance between the first stage 33 and the second stage 40 becomes a predetermined width suitable for cutting the sheet by the cutter unit, the movement of the second stage 40 is stopped. Next, a negative pressure is supplied to the negative pressure chamber of the first stage 33, and the sheet 50 is adsorbed and held by both the holding surface 33a and the second holding surface 40a. In this state, as shown in FIG. 11C, the sheet is cut while running the cutter portion 42a in the direction perpendicular to the paper surface. (Step S4 in FIG. 10)
After cutting the sheet, as shown in FIG. 11D, the first stage 33 and the second stage 40 are moved in the direction in which the first and second stages move away from each other. The first stage 33 is moved in the arrow E direction, and the second stage 40 is moved in the arrow F direction by a predetermined distance. As a result, a large gap is provided between the image portion 50 a held by the first stage 33 and the binding margin portion 50 b held by the second stage 40. When the adhesive tape is supplied to the processing table by the taping unit, this gap is for preventing interference with the supplied sheet.

After the tape is supplied, as shown in FIG. 11E, the first stage 33 is moved in the direction of arrow F and the second stage 40 in the direction of arrow E, so that the space between the image portion 50a and the binding margin portion 50b is Make it a desired gap. (Step S6 in FIG. 10)
This desired clearance requires close control as it will be the final hinge dimensions. Since the suction holding is maintained while moving the two stages after cutting the sheet, the sheet does not shift on the holding surface.

In this manner, adhesive tapes 51a and 51b are attached from both sides as shown in FIG. 11 (E) in a state where the gaps between the cut sheets are strictly managed. Then, as shown in FIG. 11F, the pressure rollers 44a and 44b are run along the top of the tape to firmly fix the tape. (Step S7 in FIG. 10)
FIG. 12 shows the procedure of an operation (step S4 in FIG. 10) of cutting the sheet by the cutter unit. This is processing performed in the state shown in FIG.

  In the initial state of FIG. 12A, the first adhesive tape 51a guided by the guide roller 61d and the second adhesive tape 51b guided by the guide roller 62c have their adhesive surfaces facing each other. It is held by the first chuck 63a. The processing unit 41 is stopped on the opposite side to the supply side of the adhesive tape. In the processing unit 41, an upper round blade 42a and a lower round blade 42b are provided as a cutter unit. The upper circular blade 42a and the lower circular blade 42b can move up and down by an actuator, and can take a state in which they are separated from each other and a state in which the cutting edges are in contact with each other.

  As shown in FIG. 12B, the processing unit 41 moves in the arrow F direction when cutting the sheet. FIG. 11C shows a state in which the cutting is completed, and the processing unit 41 rests on the supply side of the adhesive tape. When the cutting is completed, the leading end of the adhesive tape is held by the moving chuck 63 provided in the processing unit 41, and the first chuck 63a is retracted.

  FIG. 13 shows a procedure of an operation (step S6 in FIG. 10) of supplying the adhesive tape to the processing stage in the taping unit. This is processing performed in the state shown in FIG.

  FIG. 13A shows a state in which the processing unit 41 is moving in the arrow E direction from the state of FIG. 12C. The first adhesive tape 51a and the second adhesive tape 51b are supported at three points of the moving chuck 63, the guide roller 61d, and the guide roller 62c to form a wedge-shaped sharp gap. Here, in the initial state of FIG. 13A, the guide roller 61d is positioned upward and the guide roller 62c is positioned downward, and the first adhesive tape 51a and the second adhesive tape 51b are largely separated. There is. Therefore, the acute angle of the wedge-shaped gap is large. Since the pressure-sensitive adhesive tape thus stretched passes through the large gap between the sheets cut as shown in FIG. 11D, the pressure-sensitive adhesive tape does not contact the sheet. FIG. 13B shows a state in which the movement of the processing unit 41 proceeds and the leading end of the adhesive tape is pulled out to a position where it can be held by the fixed second chuck 63b.

  Next, as shown in FIG. 13C, the leading end of the adhesive tape is held by the second chuck 63b, and the movable chuck 63 retracts. Next, the guide roller 61d is moved downward, and the guide roller 62c is moved upward, until the both are almost in contact. Then, the first adhesive tape 51a is located on the upper surface side of the gap between the image portion 50a of the sheet and the binding margin portion 50b, and the second adhesive tape 51b is located on the lower surface side of the gap between the sheets. The acute angle of the wedge-shaped clearance decreases. This state is a state shown in FIG. Here, the upper pressure-bonding roller 44a and the lower pressure-bonding roller 44b provided in the processing unit 41 are moved to clamp the adhesive tape therebetween.

  FIG. 14 shows the procedure of the operation (steps S7 and S8 in FIG. 10) of attaching and cutting the adhesive tape in the taping section. This is processing performed in the state of FIG. 11 (E) and FIG. 11 (F).

FIG. 14A shows a state in which the processing unit 41 is moving in the arrow F direction. The upper pressure-bonding roller 44a and the lower pressure-bonding roller 44b roll and travel while pressing the sheet with the upper and lower adhesive tapes. By this pressing, the adhesive tape is firmly fixed from both sides of the sheet. As shown in FIG. 14B, when the processing unit 41 is moved to the opposite end, the upper pressure contact roller 44a and the lower pressure contact roller 44b are separated. Then, one side of the adhesive tape is cut by a tape cutting cutter 45 provided in the processing unit 41. Subsequently, as shown in FIG. 14C, the processing unit 41 returns in the direction of the arrow E, and cuts the adhesive tape at the other end. (Step S8 in FIG. 10)
FIG. 15 is a top view for explaining an operation in which supply of an unprocessed sheet and discharge of a processed sheet are performed in parallel by the sheet transfer unit. By performing the two operations of supply and discharge in parallel, the processing throughput of the apparatus is improved as compared to serial processing.

  FIG. 15A shows a state when processing of one sheet 501 is completed and the next raw sheet 502 is supplied. Each suction pad of the supply arm 32 sucks the sheet 502, and each suction pad of the discharge arm 37 sucks the sheet 501. The feed tray 31 moves upward so that the top sheet contacts the suction pad during suction. When the two sheets are held by suction, the supply arm 32 and the discharge arm 37 ascend together. Next, as shown in FIG. 15B, the sheet 501 is moved in the direction of the arrow N, and the processed sheet 501 and the unprocessed sheet 502 are transferred above the discharge tray 36 and the first stage 33, respectively. Then, the first stage 33 is moved in the arrow M direction, and the second stage 40 is moved in the arrow L direction, so that the distance between the two is narrowed. At this stage, both sheets have not been placed on the stage or tray yet and have floated up.

  Next, as shown in FIG. 15C, the two arms 32g and 32h of the supply arm 32 are stretched in the arrow P direction by the actuator, and the unprocessed sheet 502 is straddled over the first stage 33 and the second stage 40. Position as. Then, the supply arm 32 and the discharge arm 37 are lowered so that the processed sheet 501 and the unprocessed sheet 502 are placed on the discharge tray 36, the first stage 33, and the second stage 40, respectively. When the negative pressure of each suction pad is cut off and suction holding is released, the supply arm 32 and the discharge arm 37 are raised, and the two arms 32g and 32h of the supply arm 32 are contracted by the actuator. Then, as shown in FIG. 15 (D), the supply arm 32 and the discharge arm 37 move in the arrow Q direction and are returned to the original state.

  From here, each process of positioning, sheet cutting, gap formation between sheets, taping, and tape cutting is sequentially performed on the sheet 502 on the processing table. During processing, the supply tray 31 is raised to cause the next green sheet 503 to be adsorbed to the suction pad of the supply arm 32, thereby preparing for the next supply. When the processing of the sheet 502 is completed, as shown in FIG. 15E, the first stage 33 is moved in the arrow L direction, and the processed sheet 502 is positioned below the discharge arm 37. This state is the same as that of FIG. 15A, and the same processing is repeated thereafter.

  FIG. 16 shows the structure of a suction pad (suction part) provided in the supply arm 32. As shown in FIG. Here, although the suction pad 32c is described as an example, the plurality of suction pads all have the same structure. The suction pad of the discharge arm 37 also has the same structure.

  The suction pad 32 c includes a negative pressure chamber 322 partitioned by a circumferential outer peripheral wall 324. As shown in FIGS. 16A and 16B, concentric ribs 323 having substantially the same height as the outer peripheral wall are formed inside the negative pressure chamber. The negative pressure chamber 322 is connected to a negative pressure source via the tube 321, and the sheet is held by suction by the supplied negative pressure.

  If there is no rib 323, as shown in FIG. 16C, the uppermost sheet 501 swells under negative pressure inside the rib 323, and a negative pressure is generated between the uppermost sheet 501 and the second sheet 502. A space 325 is formed. When the sheet 501 is lifted by this negative pressure space, the second sheet 502 is also lifted together and the separation performance is degraded. On the other hand, by providing the concentric rib 323, the front end of the rib is held in contact with the sheet, and the sheet is prevented from being lifted by the negative pressure, thereby achieving good separation performance. That is, the adsorbing portion has concentric ribs formed inside the outer peripheral wall, and when the sheet is held by suction, the outer peripheral wall and the tips of the ribs contact the sheet.

  In this device. In order to further improve the separation performance of the sheets stacked on the supply tray, a blower 70 as shown in FIG. 17A is provided. The blower 70 blows air from the side of the sheet stacked on the supply tray 31 when picking up the sheet. The air flow intrudes between the first sheet 501 and the sheet therebelow to assist the separation of the first sheet 501. As shown in FIG. 17B, since the first sheet 501 abuts against the height regulation member 71 of the stack sheet, an air flow 73 is generated between the first sheet 501 and the sheet therebelow. It is hard to enter. Therefore, as shown in FIG. 17C, a dedicated suction pad 32k (sucking portion) is provided which lifts the vicinity of the end portion of the sheet 501 near the blower 70. Before the other suction pads 32c, 32d, 32e, 32f lift the sheet 501, lift the end of the sheet 501 with the suction pad 32k, blow air from the side to the lifted end, and the second sheet To facilitate the separation of the sheet.

  According to the present invention, when the binding margin portion, the hinge, and the image portion of a plurality of pages are linearly arranged in each page, and the back side is the lower side and the back side is the upper side, It is characterized in that the position of the end on the image portion side is located on the center page above the end page. As such a book, an example shown in FIG. 1B will be described.

  In FIG. 1B, the end 54 on the image portion side of the hinge is a portion where the hinge 51a and the image portion 50a are connected. The position of the end 54 on the image portion side of the hinge is located on the center page above the end page. In FIG. 1B, such a shape is realized by changing the length of the binding margin portion 50b. The length of the hinge 51a is the same on all pages. That is, the length of the binding margin portion 50b of the center page is made longer than the length of the binding margin portion 50b of the end page.

  The length of the binding margin portion 50b is preferably determined according to the thickness of the binding margin portion, the thickness of the image portion on which the image is formed, and the number of sheets. For example, when the image portion is 10 sheets or more and 100 sheets or less and the thickness of one image portion is 0.1 mm or more and 0.5 mm or less, the length of the binding margin portion of the end page is 5.0 mm or more. It is preferable that the length of the binding margin portion of the center page is set to 5.2 mm or more and 18.0 mm or less. It is preferable that the length of the binding margin of the page between the end page and the center page be a length between the length of the binding margin of the end page and the length of the binding margin of the center page.

  Although FIG. 1B shows a diagram in which the length of the binding margin always changes from the end page to the center page for simplification, the page having the same length of the binding margin is shown. It may be continuous. For example, with regard to the length of the binding margin portion, the first to fifth sheets at the end are 10.0 mm, the sixth to tenth sheets are 10.5 mm, and the eleventh to fifteenth sheets are eleventh .0 mm, the 16th to 20th sheets are 10.5mm, and the 21st to 25th sheets are 10.0mm. From a manufacturing point of view, it is preferable to continue the pages having the same length of the binding margin portion in this manner. In such a case, the joint portion of the binding margin portion with the hinge and the end of the hinge 51a far from the back surface both have a mountain-like and step-like shape in the entire book. From the manufacturing point of view, it is preferable to form a step-like shape in which pages having binding margins of the same length are continuous. On the other hand, from the viewpoint of improving the spreadability, it is preferable to form a shape in which pages having a binding margin portion of the same length are not continuous.

  When covering the surface of the image portion 50a with adhesive tape and stretching the adhesive tape to form the hinge 51a, the length of the hinge 51a is limited by the number of pages of a book, etc., and the length of the hinge 51a is sufficiently controlled. It can be difficult to do. On the other hand, if it is a method of changing the length of the binding margin portion 50b, it is hard to receive such a restriction.

  Regarding the method of bookbinding such a book, the details of the apparatus and the like are basically the same as the contents described with reference to FIG.

  The present invention may change both the length of the hinge 51a and the length of the binding margin portion 50b as the page advances. Such a book will be described with reference to FIG. 1 (c).

The book shown in FIG. 1C has the same length up to three from the leftmost page, the longest next to the leftmost page in terms of the length of the binding margin portion 50b, and the next page (rightmost page) is the length between them. . On the other hand, the length of the hinge 51a gradually increases from the left end to the center, and the hinges of the center and the right end are short. As a result, the position of the end 54 on the image portion side of the hinge 51a is located on the center page above the end page. More specifically, for example, the image portion on which the image is formed is When the thickness of one image portion is 0.1 mm or more and 0.5 mm or less at 10 sheets or more and 100 sheets or less, the length of the binding margin portion is 10.0 mm from the first sheet to the 15th sheet at the end The sixth to twentieth sheets are 11.0 mm, and the twentieth to twenty-fifth sheets are 10.5 mm. In addition, regarding the length of the hinge, 0.5 mm from the first to fifth sheets at the end, 1.0 mm from the sixth to tenth sheets, 1.5 mm from the eleventh to fifteenth sheets in the center , And the 16th to 25th pieces are 0.5mm.

  When both the length of the hinge 51a and the length of the binding margin portion 50b are changed, it is preferable in that bookbinding is easy even if the distance from the hinge side end of the image portion 50a to the printed image is uneven. For example, with respect to the image part where the distance from the end on the hinge side of the image part to the printed image is the longest, if the distance is shorter than that, the difference of the binding margin part 50b and the position of the page are taken into consideration The length can be adjusted. Therefore, for example, page replacement and page order change can be easily performed regardless of the distance from the end on the hinge side of the image portion 50a to the print image.
