Description

  The present invention relates to a bookbinding apparatus, and more particularly to a bookbinding apparatus that performs a binding process on accumulated paper.

Various techniques are currently used for bookbinding and booklet production. As one of such bookbinding techniques, for example, a bookbinding apparatus has been proposed in which a solid paste is applied near a side edge of a sheet placed on a sheet placement table to form a belt-like paste application portion. (For example, refer to Patent Document 1). As another bookbinding technique, a bookbinding apparatus has been proposed that creates a saddle-stitched folded booklet by introducing a bundle of sheets subjected to a staple binding process between a pair of folding rollers using a folding knife. (For example, refer to Patent Document 2).

  In recent years, among such various bookbinding techniques, there is an increasing demand for creating a booklet using a bookbinding technique according to the application. For example, bookbinding technology is widely used to create a saddle stitched booklet by folding the paper bundle after it has been stapled, but in an environment where safety is required for the booklet, such as a school, a binding needle is used. In some cases, the bookbinding technique using glue is preferred over the bookbinding technique. However, if many bookbinding apparatuses are installed to use different bookbinding techniques depending on the purpose, the installation space may become enormous.

  Therefore, the present invention has been made to solve the above-described problems, and an object of the present invention is to enable a plurality of bookbinding techniques to be used while suppressing an increase in installation space.

  In order to solve the above-described problems, a bookbinding apparatus according to an aspect of the present invention includes a paper storage unit that stores paper, a staple binding unit that performs a staple binding process on paper stored in the paper storage unit, and a paper storage unit. Each of the staple binding unit and the glue binding unit is detachable so as to accommodate either one of the glue binding units for performing a crimping process for pressing the sheets glued to at least one of the opposing paper surfaces among the accumulated sheets. And a binding unit accommodating portion provided in the.

  According to this aspect, it is possible to execute both the staple binding process and the crimping process with one bookbinding apparatus. In addition, since either the needle binding unit or the gluing unit is attached, space-saving of the bookbinding apparatus can be achieved compared to the case where both are attached.

  The glue binding unit may perform the crimping process by gluing the paper accumulated at the top of the paper accumulation unit and pressing the paper accumulated at the top. According to this aspect, the gluing process can be performed together with the crimping process. For this reason, compared with the case where the gluing process is performed on the paper in another space, the space of the bookbinding apparatus can be saved.

  The bookbinding apparatus according to an aspect of the present invention may further include unit specifying means for specifying whether the unit mounted in the binding unit housing portion is a needle binding unit or a glue binding unit. According to this aspect, it is possible to execute control according to the unit attached to the binding unit housing portion.

  The bookbinding apparatus according to an aspect of the present invention further includes notification means for notifying a user whether the unit attached to the binding unit housing portion is a needle binding unit or a glue binding unit, using a specification result by the unit specifying means. Also good. According to this aspect, the user can easily grasp which unit is attached to the binding unit housing portion. For this reason, for example, when it is desired to execute the needle binding process, an erroneous operation such as erroneously executing the glue binding process can be suppressed.

  In the bookbinding apparatus according to an aspect of the present invention, when the attached unit is specified as the needle binding unit, the needle binding unit is driven when the needle binding process is executed, and the attached unit is the glue binding unit. If specified, it may further comprise a drive means for driving the glue binding unit when the crimping process is executed. According to this aspect, it is possible to smoothly execute the staple binding process and the crimping process using the identification result by the unit identification unit.

  The driving means may have a common drive source that drives the needle binding unit when the needle binding process is executed and drives the glue binding unit when the pressure bonding process is executed. According to this aspect, it is possible to reduce the space for installing the drive source and the like as compared with the case where the drive source for driving the staple unit and the drive source for driving the glue binding unit are provided separately.

  The bookbinding apparatus according to an aspect of the present invention may further include an attachment sensor that detects attachment of the staple binding unit and the glue binding unit to each binding unit housing portion. The unit specifying means specifies that the attached unit is a needle binding unit when the attachment of the needle binding unit is detected, and the attached unit detects the attachment of the glue binding unit when the attachment of the glue binding unit is detected. You may specify that it is a unit. According to this aspect, it is possible to easily specify whether the attached unit is a needle binding unit or a glue binding unit without requiring input by the user separately.

  The bookbinding apparatus according to an aspect of the present invention may further include an input unit capable of inputting by a user indicating whether the attached unit is a needle binding unit or a glue binding unit. The unit specifying means specifies that the attached unit is a needle binding unit when an input is made by the user indicating that the attached unit is a needle binding unit, and the attached unit is a glue binding unit. When the user indicates that the attached unit is specified, the attached unit may be specified as the glue binding unit. According to this aspect, it is possible to specify a unit that is mounted according to the user's will.

  The binding unit storage unit stores the paper at a position where the binding needle penetrates the binding needle from one surface of the paper accumulated in the paper accumulation unit to the other surface, and the position where the binding needle is penetrated by the needle binding unit. Each of the glue binding units that press one side of the paper accumulated in the unit is detachably provided, and the paper accumulation unit is a leg of the binding needle that is penetrated by the paper accumulated in the paper accumulation unit by the needle binding unit. A clincher that bends the portion and a receiving member that supports the other surface when one surface of the paper accumulated in the paper accumulation portion is pressed by the glue binding unit may be provided. The receiving member is provided so that the clincher can be advanced and retracted to a clinch position where the leg portion of the binding needle is bent. When the needle binding process is executed, the receiving member is retracted from the clinch position, and when the crimping process is executed, the clincher is advanced to the clinch position. Good.

  According to this aspect, it is possible to bind the same portion of the paper when performing either the staple binding process or the crimping process. For this reason, for example, the operation of aligning sheets performed before binding can be performed in the same manner regardless of which of the staple binding unit and the glue binding unit is mounted.

  The binding unit housing unit is configured to pass the binding needle from one surface of the paper accumulated in the paper accumulation unit to the other surface, and the position where the binding needle is penetrated by the needle binding unit. Each of the glue binding units that press one side of the paper accumulated in the accumulating unit is detachably provided, and the paper accumulating unit includes a binding needle penetrating the paper accumulated in the paper accumulating unit by the needle binding unit. A clincher that bends the leg, and a receiving member that supports the other side of the paper accumulated in the paper accumulating unit by the glue binding unit at a place where the other side is pressed by the glue binding unit. May be.

  According to this aspect, it is possible to easily avoid the interference between the paper support position and the clincher position when the paper is pressed during the crimping process. For this reason, even when a bookbinding apparatus in which both the needle binding unit and the glue binding unit are detachable is designed, the receiving member and the clincher can be easily designed.

  According to the present invention, it is possible to selectively use a plurality of bookbinding techniques while suppressing an increase in installation space.

  Hereinafter, embodiments of the present invention (hereinafter referred to as embodiments) will be described in detail with reference to the drawings.

(First embodiment)
FIG. 1 is an overall configuration diagram of a bookbinding apparatus 10 according to the first embodiment. The bookbinding apparatus 10 includes a paper feeding device 12, a saddle stitch folding device 14, a cutting device 16, a display 18, a control panel 20, and an electronic control unit 22. The electronic control unit 22 includes a CPU that executes various arithmetic processes, a ROM that stores various control programs, and a RAM that is used as a work area for data storage and program execution, and controls the bookbinding process by the bookbinding apparatus 10. .

  The sheet feeding device 12 includes an A tray 24A and a B tray 24B (hereinafter collectively referred to as “tray 24” as necessary). On the tray 24, sheets on which images are formed by an image forming method such as printing, electrophotographic method, and ink jet method are stacked. Instead of the paper feeding device 12, an image forming apparatus using, for example, a printing machine, an electrophotographic method, an ink jet method, or the like may be provided. A separate feeding mechanism 26 is provided for each of the A tray 24A and the B tray 24B. The separation feeding mechanism 26 separates and sends out the uppermost sheet among the sheets stacked on the corresponding tray 24. The separation and feeding mechanism 26 according to the first embodiment is an air suction type. Since the air suction type separation and feeding mechanism is known, its detailed description is omitted. Of course, a so-called friction type separation / feed mechanism may be provided instead of the air suction type separation / feed mechanism.

  In addition, the sheet feeding device 12 includes a lifting mechanism (not shown) that raises and lowers each of the trays 24 and a sheet height sensor (not shown) that detects the height of the sheets stacked on each of the trays 24. . The electronic control unit 22 stops the raising of the tray 24 when it is detected that the uppermost sheet among the sheets stacked on the tray 24 has reached the feedable height. In this way, the electronic control unit 22 maintains the height of the sheets stacked on the top of the tray 24 at a sheet feedable height, and enables the sheet feeding mechanism 26 to continuously feed the sheets. The common conveyance path 28 joins the sheet conveyance path for conveying the sheet sent out from the A tray 24A and the sheet conveyance path for conveying the sheet sent out from the B tray 24B.

  The saddle stitch folding device 14 includes a gluing mechanism 30 </ b> A and a folding mechanism 32. The gluing mechanism 30 </ b> A includes a transport plate 36, a transport roller 38, a pusher 40, a binding stopper 42, and a binding unit housing portion 44. The sheet fed from the common conveyance path 28 of the sheet feeding device 12 is fed to the sheet conveyance path 34 of the saddle stitch folding device 14. The transport plate 36 is provided on the downstream side of the paper transport path 34 in the paper transport direction (hereinafter referred to as “downstream side”). The transport plate 36 is arranged such that the upper surface is lower than the paper transport path 34. Each level difference at this time is made larger than the maximum thickness of the sheet bundle before the folding process of the saddle stitched booklet that can be created by the bookbinding apparatus 10.

  The pusher 40 is disposed in a boundary region between the paper transport path 34 and the transport plate 36. The pusher 40 is provided so as to protrude upward from the upper surface of the transport plate 36 in a region below the paper transport path 34. The pusher 40 is movable in parallel with the paper transport direction via a ball screw mechanism by operating a pusher moving motor (not shown).

  The binding stopper 42 is disposed on the downstream side of the pusher 40 and is provided so as to be able to advance and retract upward from the upper surface of the transport plate 36. The binding stopper 42 is movable in parallel to the paper transport direction via a ball screw mechanism by operating a binding stopper moving motor (not shown). Between the pusher 40 and the binding stopper 42, there is a side guide (not shown) that aligns the paper stacked on the transport plate 36 in a direction perpendicular to the paper transport direction (hereinafter referred to as “paper width direction”). A pair is provided so as to sandwich the transport plate 36. The pair of side guides are movable in the paper width direction so as to approach and separate from each other when a side guide moving motor (not shown) is operated by a so-called center distribution method. In this manner, the area above the transport plate 36 surrounded by the pusher 40, the binding stopper 42, and the pair of side guides is defined as the sheet storage unit 46. The paper accumulating unit 46 is used as an area for accumulating paper on which needle binding processing or glue binding processing is performed. In the upper part of the paper accumulating unit 46, a binding unit housing portion 44 is provided in which each of the needle binding unit and the gluing unit can be attached and detached so that either one of a needle binding unit and a gluing unit, which will be described later, is housed.

  The paper sent to the paper transport path 34 is sent to the paper storage unit 46 by a pair of transport rollers 38. The conveyance roller 38 is formed in a barrel shape whose center is swollen, and gives a firmness to the sheet fed to the sheet accumulation unit 46. As a result, even when the sheet glued by the gluing unit is accumulated in the sheet accumulation unit 46, the sheet accumulated in the uppermost position of the sheet accumulation unit 46 while the sheet is being fed into the sheet accumulation unit 46. Suppresses adhesion.

  FIG. 2 is a diagram illustrating a configuration of the gluing mechanism 30A when the staple binding unit 96 is accommodated in the binding unit accommodating portion 44 in the first embodiment. In the first embodiment, stapling processing is employed as the staple binding processing method, and the staple binding unit 96 allows the binding needle to penetrate from one surface of the paper accumulated in the paper accumulation unit 46 to the other surface. The binding needle penetrating the sheet is bent by a clincher described later, and the stapling process is completed. Therefore, the stapler is constituted by the needle binding unit 96 and the clincher. The needle binding unit 96 may employ a stitcher that pulls out one wire from the spool, cuts the wire into a predetermined length, and bends it into a U-shape.

  The needle binding unit 96 includes a main body 97, a pusher 98, a needle row 100, and a mounting member 102. The main body 97 can be attached to and detached from a needle binding unit mounting portion (not shown) provided in the binding unit housing portion 44. A needle row 100 is wound around the main body 97 to be supplied below the pusher 98. The pusher 98 is attached to the main body 97 so as to be lowered. The needle binding unit 96 is provided with a needle shape forming member (not shown) that takes out one needle from the needle row 100 and bends it into a U shape. The needle shape forming member lowers the pusher 98 and bends one needle at the tip of the needle row 100 into a U shape. The pusher 98 causes the bent needle to penetrate the paper stored in the paper storage unit 46. Since the stapler for passing the needle through the paper in this way is a known technique, further detailed description is omitted.

  The transport plate 36 is provided with an opening extending in the paper width direction, and the receiving unit 90 is disposed in the opening. The receiving unit 90 includes a receiving member 92 and a clincher 94. The receiving member 92 is formed in a thick plate shape, and is disposed so that one end surface thereof extends in the paper width direction and is flush with the upper surface of the transport plate 36. The receiving member 92 has a receiving surface 92 a that supports the lowermost sheet lower surface when the uppermost sheet upper surface stacked on the sheet accumulation unit 46 is pressed by the glue binding unit 110. The receiving member 92 is provided with an insertion hole, and the clincher 94 is inserted into the insertion hole. When the binding needle passes through the paper accumulated in the paper accumulating unit 46 by the staple binding unit 96, the clincher 94 can be advanced upward to bend the leg of the binding needle by the operation of a motor (not shown). Provided. Since the clincher that bends the leg portion of the binding needle is a known technique, the description thereof is omitted.

  A mounting member 102 is attached above the pusher 98. On the other hand, the gluing mechanism 30A includes a mounted member 104 and a drive mechanism (not shown) that moves the mounted member 104 up and down. A main body frame (not shown) constituting the binding unit housing portion 44 is provided with a mounted portion (not shown) for detachably supporting the needle binding unit 96. The needle binding unit 96 is also provided with a mounting portion (not shown) for mounting on the main body frame. The needle binding unit 96 is mounted on the bookbinding apparatus 10 by engaging the mounting portion of the needle binding unit 96 with the mounted portion of the binding unit housing portion 44. At this time, the mounting member 102 is mounted on the mounted member 104.

  A mounting sensor 106 is attached to the mounted member 104. For example, the attachment sensor 106 may include two terminals having different electrical continuity states when the needle binding unit 96 is attached and when the glue binding unit 110 is attached. The mounting sensor 106 is connected to the electronic control unit 22. The electronic control unit 22 uses the detection result of the mounting sensor 106 to specify whether the unit mounted in the binding unit housing unit 44 is a needle binding unit 96 or a glue binding unit described later. Therefore, the electronic control unit 22 functions as unit specifying means.

  When the attachment of either the staple binding unit 96 or the glue binding unit 110 is detected, the electronic control unit 22 detects whether the unit attached to the control unit 20 in the binding unit storage unit 44 is the needle binding unit 96 or the glue binding unit 110. Is displayed on the display 18 to notify the user. Therefore, the electronic control unit 22 and the display 18 function as notification means. For example, when the attachment of the needle binding unit 96 is detected, the mode may be shifted to the stapler mode, and when the attachment of the glue binding unit 110 is detected, the mode may be shifted to the glue binding mode. In the stapler mode, the user can input items related to the staple binding process using the control panel 20. Further, when the start button of the control panel 20 is pressed, the operation of each actuator in the gluing mechanism 30A is controlled so as to execute the needle binding process. In the glue binding mode, the user can use the control panel 20 to input items related to the glue binding process. Further, when the start button is pressed, the operation of each actuator in the gluing mechanism 30A is controlled so as to execute the gluing process.

  The drive mechanism has a cam mechanism (not shown) and a binding motor (not shown). By actuating the binding motor, the mounted member 104 is lowered or raised via the cam mechanism. For this reason, when the needle binding unit 96 is mounted in the binding unit housing portion 44, the needle is driven into the paper stored in the paper storage portion 46 by operating the binding motor. The clincher 94 operates in accordance with the driving operation of the needle to bend the leg portion of the needle protruding from the lower surface of the paper. In this way, the staple binding process for binding the paper with the needle is executed.

  The folding stopper 48 is disposed in the vicinity of the downstream end of the transport plate 36 so as to protrude above the upper surface of the transport plate 36. The folding stopper 48 is connected to a stopper moving motor (not shown) via a ball screw mechanism, and moves in the paper transport direction when the stopper moving motor is operated.

  FIG. 3 is a diagram illustrating the configuration of the gluing mechanism 30A when the glue binding unit 110 is accommodated in the binding unit accommodation portion 44 in the first embodiment. The glue binding unit 110 includes a glue cassette 112 and an intermediate unit 114. The glue cassette 112 includes a case 118, a glue sheet 120, a feeding reel 122, a take-up reel 124, a glue transfer roller 126, a take-up gear 128, a feed roller 130, a feed gear 132, and an idler gear 134. The case 118 has an opening on the lower surface, and an attachment portion 118a that protrudes from the upper surface and extends in the paper transport direction. For ease of understanding, the case 118 is shown in cross section in FIG.

  The glue sheet 120 as the glue member is configured such that glue is attached to one surface of a long flexible sheet. The supply reel 122 is rotatably attached to the case 118 in a state in which the glue sheet 120 is wound so that the glue-attached surface to which the glue is attached is on the outside. By pressing the side of the glue sheet 120 to which the glue is applied to the paper, the glue at the pressed part is peeled off from the sheet and transferred to the paper. Since such a glue sheet is publicly known, a detailed description of the configuration of the glue sheet 120 is omitted.

  The take-up reel 124 is rotatably attached to the case 118 so as to be arranged beside the supply reel 122. A glue transfer roller 126 as a glue transfer member is rotatably attached to the case 118 at a lower side opposite to the side where the feeding reel 122 is present when viewed from the take-up reel 124. At this time, the glue transfer roller 126 is disposed so as to protrude downward from the opening on the lower surface of the case 118. The glue sheet 120 wound around the supply reel 122 has the glue-attached surface on the back surface bonded to the outer surface of the glue transfer roller 126 and one end fixed to the outer surface of the take-up reel 124. When the take-up reel 124 rotates, the glue sheet 120 wound around the feed reel 122 via the outer surface of the glue transfer roller 126 is taken up by the take-up reel 124. The feeding reel 122 is fitted on the rotating shaft so as to generate appropriate friction. For this reason, even if the glue sheet 120 is taken up by the take-up reel 124, the contact portion between the supply reel 122 and its rotating shaft functions as a torque limiter, and an appropriate tension is maintained on the glue sheet 120. The glue transfer roller 126 is made of an elastic material so that the pressed portion is compressed to increase the glued area.

  The glue sheet 120 extending between the glue transfer roller 126 and the take-up reel 124 is sandwiched between a pair of feed rollers 130. A feed gear 132 is fixed to the lower feed roller 130 of the pair of feed rollers 130 so as to rotate coaxially. When rotational torque is applied to the feed gear 132, the lower feed roller 130 connected to the feed gear 132 rotates, and the upper feed roller 130 is driven accordingly. By rotating the pair of feed rollers 130 in this way, the glue sheet 120 is fed toward the take-up reel 124. Therefore, the pair of feed rollers 130 and the feed gear 132 function as a feed mechanism that feeds the glue sheet 120.

  An idler gear 134 is fixed to the upper feed roller 130 so as to rotate coaxially. A take-up gear 128 is fixed to the take-up reel 124 so as to rotate coaxially. The idler gear 134 meshes with the take-up gear 128. As the idler gear 134 is driven, the take-up gear 128 rotates, and the glue sheet 120 that is fed is taken up by the take-up reel 124. The take-up reel 124 is fitted on the rotating shaft so as to generate appropriate friction. In a state in which the take-up reel 124 and its rotation shaft do not slide, the take-up gear 128 and the idler gear 134 are provided so that the take-up speed by the take-up reel 124 is faster than the feed speed by the feed roller 130. Yes. With such a configuration, even if the glue sheet 120 is fed toward the take-up reel 124 by the feed roller 130, the contact portion between the take-up reel 124 and its rotation shaft functions as a torque limiter, and maintains an appropriate tension. In this state, the take-up reel 124 can take up the paste sheet 120.

  The intermediate unit 114 includes a shaft 152, a mounting member 154, a stopper 156, a moving member 158, and a coil spring 160. The moving member 158 is provided with a mounting portion 158 a that can be attached to and detached from the mounted member 104. Further, the moving member 158 is provided with an insertion hole having the same diameter as the shaft 152, and the shaft 152 is inserted into the insertion hole. A stopper 156 is fixed in the vicinity of the upper end of the shaft 152, and the downward movement of the shaft 152 is restricted by the stopper 156 coming into contact with the upper end of the moving member 158. An attachment member 154 is fixed to the lower end of the shaft 152. A coil spring 160 is disposed between the lower end of the moving member 158 and the upper end of the attachment member 154 so as to be wound around the shaft 152. The coil spring 160 applies a biasing force in a direction in which the moving member 158 and the mounting member 154 are separated from each other.

  The attachment member 154 is formed with an attachment groove 154a that extends in the paper transport direction and has the same cross section as the attachment portion 118a. The attachment portion 118a of the glue cassette 112 is inserted into the attachment groove 154a of the intermediate unit 114, and the glue binding unit 110 is configured. By making the glue cassette 112 removable from the intermediate unit 114 in this way, when the glue sheet 120 of the glue cassette 112 is used up, only the glue cassette 112 can be replaced. For this reason, consumables costs can be suppressed.

  The rack gear mounting unit 140 is configured with a rack gear 144 fixed to a mounting bracket 142. The main body frame constituting the binding unit housing portion 44 is provided with a mounted portion (not shown) for detachably supporting the mounting bracket 142. The mounting bracket 142 is also provided with a mounting portion (not shown) for mounting on the main body frame. The rack gear mounting unit 140 is mounted on the bookbinding apparatus 10 by engaging the mounting portion of the mounting bracket 142 with the mounted portion of the binding unit housing portion 44. As described above, in the first embodiment, the binding unit accommodating portion 44 is detachably provided so as to accommodate either the needle binding unit 96 or the glue binding unit 110. Thereby, space saving of a bookbinding apparatus can be achieved compared with the case where both a needle binding unit and a glue binding unit are provided in a bookbinding apparatus.

  The rack gear mounting unit 140 is mounted in front of the glue binding unit 110. When the mounting portion 158a is inserted into the mounted member 104 and the glue binding unit 110 is mounted while the rack gear mounting unit 140 is mounted, the feed gear 132 and the rack gear 144 mesh with each other so as to transmit the driving force.

  When the glue binding unit 110 is mounted in the binding unit housing portion 44, when the binding motor is operated and the mounted member 104 is lowered or raised via the cam mechanism, the glue cassette 112 is also lowered via the coil spring 160. Or rise. At this time, the glue is transferred to the upper surface of the uppermost sheet among the sheets in which the glue sheet 120 is accumulated in the sheet accumulation unit 46. In this way, the glue binding process is executed.

  When the glue cassette 112 descends, the feed gear 132 rotates while moving downward along the rack gear 144. As a result, the feed roller 130 rotates, and the paste sheet 120 until the non-transferred glue sheet 120 covers the outer periphery below the glue transfer roller 126 so that the portion of the glue sheet 120 to which no glue is transferred is pressed against the paper. Will be sent. The rack gear 144 drives the feed roller 130 by using the force that the intermediate unit 114 lowers the glue cassette 112 in this way.

  Note that the gear portion of the rack gear 144 may be deleted below the rack gear 144. Accordingly, it is possible to avoid the glue sheet 120 being fed even when the glue cassette 112 is lowered and the glue transfer roller 126 presses the glue sheet 120 against the upper surface of the sheet.

  The feed gear 132 is connected to the lower feed roller 130 via a one-way clutch (not shown). This one-way clutch transmits the rotational torque of the feed gear 132 to the feed roller 130 when the glue cassette 112 moves downward, and the rotational torque of the feed gear 132 to the feed roller 130 when the glue cassette 112 moves upward. Avoid being transmitted. Therefore, when the glue cassette 120 is raised after the glue sheet 120 is pressed against the uppermost sheet upper surface accumulated in the sheet accumulation unit 46, the feed gear 132 rotates by moving along the idler gear 134. The feed roller 130 is kept from rotating. Thereby, it can avoid sending the glue sheet 120 to a reverse direction.

  When two or more sheets are accumulated in the sheet accumulation unit 46, the glue sheets 120 are pressed against the upper surface of the uppermost sheet, whereby the sheets accumulated below are also pressed together. In this way, the glue binding unit 110 glues the paper accumulated at the top of the paper accumulation unit 46 and presses the paper accumulated at the top so as to press the sheets accumulated below to bond. Execute the crimping process to bind with

  The drive mechanism that raises and lowers the mounting sensor 106 drives the needle binding unit when the needle binding process is executed, and drives the glue binding unit 110 when the glue binding process is executed. At this time, the binding motor functions as a common drive source that drives the needle binding unit 96 when the staple binding process is executed and drives the glue binding unit 110 when the crimping process is executed.

  4 is a view of the glue binding unit 110 seen from the viewpoint P in FIG. On the front and rear side surfaces of the case 118, a pressing unit 180 is provided. The pressing unit 180 includes a guide portion 182, a shaft 184, a stopper 186, a sheet pressing member 188, and a coil spring 190.

  The guide portion 182 is integrally formed with the case 118 so as to protrude from the side surface of the case 118. The guide portion 182 is provided with an insertion hole extending in the vertical direction, and the shaft 184 is inserted into the insertion hole. The stopper 186 has a larger diameter than the shaft 184 and is integrally attached to the upper end of the shaft 184 so as to restrict the downward movement of the shaft 184.

  The display 18 is connected to the electronic control unit 22. The electronic control unit 22 generates display data to be displayed on the display 18. The control panel 20 is connected to the electronic control unit 22, and when the control panel 20 is operated by the user, an operation signal is output to the electronic control unit 22.

  The user can input the paper size using the control panel 20. The electronic control unit 22 acquires the paper size input by the user as size information. The electronic control unit 22 uses the acquired size information to set a folding line on the paper. Specifically, the electronic control unit 22 uses the information indicating the length in the transport direction of the paper included in the acquired size information, and uses a straight line that is a half of the length in the transport direction from the leading edge of the transported paper. Is set as the fold line. Note that the user can input the distance from the leading edge of the sheet to be conveyed as the position of the folding line on the setting screen. The electronic control unit 22 may set a straight line at a distance from the front end of the paper input by the user as the folding line.

  The electronic control unit 22 is connected to a solenoid that switches between suction and stop of air in the separation / feed mechanism 26 and a motor that drives a roller that meshes with the conveyance belt. The electronic control unit 22 controls the feeding of the sheet from the sheet feeding device 12 by controlling the operation of the solenoid and the motor to switch the suction and stop of the suction while driving the conveyance belt.

  The electronic control unit 22 is connected to the paper conveyance motor 202, the binding motor 204, the pusher movement motor 206, the binding stopper movement motor 208, the receiving unit movement motor 210, and the stopper solenoid 212 in the gluing mechanism 30A. Control the operation of The paper transport motor 202 drives the transport roller 38. The binding motor 204 moves the needle binding unit 96 or the glue binding unit 110 up and down. The pusher moving motor 206 moves the pusher 40 in the paper transport direction. The binding stopper moving motor 208 moves the binding stopper 42 in the paper transport direction. The receiving unit moving motor 210 moves the receiving unit 90 in the paper width direction. The stopper solenoid 212 moves the binding stopper 42 upward and backward from the transport plate 36.

  The electronic control unit 22 is connected to a folding stopper moving motor 214, a folding knife moving motor 216, and a folding roller driving motor 218 in the folding mechanism 32. The folding stopper moving motor 214 moves the folding stopper 48 in the paper transport direction. The folding knife moving motor 216 raises the folding knife 50 toward the pair of folding rollers 52. The folding roller drive motor 218 drives the pair of folding rollers 52.

  The electronic control unit 22 is connected to the cutting stopper moving motor 220 and the top and bottom cutting blade moving motor 222 in the cutting device 16. The cutting stopper moving motor 220 moves the cutting stopper 62 in the paper transport direction. The top and bottom cutting blade moving motor 222 moves the top and bottom cutting blades in the direction of approaching or separating from each other in the paper width direction.

  FIG. 6 is a flowchart illustrating a bookbinding procedure of the bookbinding apparatus according to the first embodiment. The processing in this flowchart is performed by a sheet feeding device until the conveyance of the total number of sheets obtained by multiplying the number of booklets input by the user and the number of sheets constituting one booklet after the start button is pressed by the user is completed. 12 is repeated at every sheet feeding timing.

  In the first embodiment, the glue binding unit 110 performs glue binding processing on one surface of the paper stacked on the paper storage unit 46 at a location overlapping the position where the staple is penetrated by the needle binding unit 96. Therefore, if the clincher 94 is present at the point where the glue sheet 120 is pressed, the crimping force at that part may be lower than at other parts. Therefore, the electronic control unit 22 determines whether or not the receiving unit 90 has been moved with reference to the receiving unit movement flag (S10). If the receiving unit 90 has not been moved (N in S10), the electronic control unit 22 uses the detection result of the mounting sensor 106 to determine whether or not the binding unit housing unit 44 is mounted on the staple binding unit 96. Determine (S12).

  When the unit attached to the binding unit housing portion 44 is the staple binding unit 96 (Y in S12), the electronic control unit 22 operates the receiving unit moving motor 210 to move the receiving unit 90 in the paper width direction. The clincher 94 is placed at the binding position (S14). The binding position in this case refers to a position where the binding needle is driven by the needle binding unit 96. When the unit attached to the binding unit housing portion 44 is the glue binding unit 110 (N in S12), the electronic control unit 22 operates the receiving unit moving motor 210 to move the receiving unit 90 in the paper width direction. The receiving surface 92a is arranged at the binding position (S16). The binding position in this case refers to the glue transfer position by the glue binding unit 110.

  In this manner, the receiving member 92 is provided so as to be movable in the paper width direction so that the receiving surface 92a advances and retreats at a clinching position where the clincher 94 bends the leg portion of the binding needle. The receiving member 92 moves so that the receiving surface 92a is retracted from the clinching position when the staple binding process is executed, and the receiving surface 92a is advanced to the clinching position when the crimping process is executed. When the movement of the receiving unit 90 is completed, the electronic control unit 22 sets the receiving unit movement flag to ON. If the receiving unit 90 has already been moved (Y in S10), the processes in S12 to S16 are skipped.

  The electronic control unit 22 refers to the binding stopper movement flag and the pusher movement flag, and determines whether or not the movement of the binding stopper 42 and the pusher 40 has been completed (S18). When the movement of the binding stopper 42 and the pusher 40 is not completed (N in S18), the electronic control unit 22 first refers to the acquired size information. The electronic control unit 22 binds so that the distance between the binding stopper 42 and the pusher 40 is the same as the length in the sheet conveyance direction of the sheet size indicated by the size information, and the folding line of the stored sheet is positioned at the binding position. The stopper 42 and the pusher 40 are moved (S20). When the movement of the binding stopper 42 and the pusher 40 is completed, the electronic control unit 22 sets the binding stopper movement flag and the pusher movement flag to ON. When the movement of the binding stopper 42 and the pusher 40 is completed (Y in S18), the process of S20 is skipped.

  Next, the electronic control unit 22 operates the separation feeding mechanism 26 to execute the paper feeding process (S22), and accumulates the paper in the paper accumulating unit 46 (S24). When sheets are accumulated in the sheet accumulation unit 46, the electronic control unit 22 uses the detection result of the attachment sensor 106 to determine whether the unit attached to the binding unit accommodation unit 44 is the staple binding unit 96 or not. (S26).

  When the unit attached to the binding unit accommodation unit 44 is the needle binding unit 96 (Y in S26), the electronic control unit 22 determines whether or not it is the last sheet of the booklet (S28). At this time, based on the number of sheets fed from the start of the bookbinding process and the number of sheets constituting one booklet input by the user, the electronic control unit 22 finally conveys the conveyed sheet among the sheets constituting the booklet. It is determined whether or not the sheet is conveyed. If it is not the last sheet of the booklet (N in S28), the processes in S30 to S38 are skipped, and the processes in this flowchart are once ended. When it is the last sheet of the booklet (Y in S28), the electronic control unit 22 operates the binding motor 204 to lower the pusher 98 of the staple binding unit 96, and binds the staples to the sheets stored in the sheet storage unit 46. Is executed (S30).

  When the staple binding process is completed, the electronic control unit 22 operates the folding stopper moving motor 214 and adjusts the position of the folding stopper 48 so as to contact the folding line when the folding knife 50 is raised (S32). Specifically, the electronic control unit 22 sets the distance from the position where the folding knife 50 contacts the paper to the folding stopper 48 to be half the length of the paper in the paper conveyance direction indicated by the acquired size information. Then, the folding stopper 48 is moved.

  Next, the electronic control unit 22 operates the pusher moving motor 206 to convey the bound sheet bundle toward the folding mechanism 32 by the pusher 40, and stops conveyance at the timing when the leading end of the sheet bundle contacts the folding stopper 48. (S34). When the sheet bundle is conveyed to the folding mechanism 32, the electronic control unit 22 operates the pusher moving motor 206 again to return the pusher 40 to the original position.

  When the sheet bundle is sent to the folding mechanism 32, the electronic control unit 22 executes a folding process (S36). Specifically, the electronic control unit 22 operates the folding knife moving motor 216 to raise the folding knife 50 while operating the folding roller driving motor 218 to drive the pair of folding rollers 52. As a result, the folding line of the sheet bundle is wound around the folding roller 52, the sheet bundle is folded, and a half-folded booklet is created.

  When the folding process is completed, the electronic control unit 22 sends the created booklet to the three-way cutting mechanism 60 through the belt conveyance mechanism 54, and executes the cutting process (S38). The user can input the finished size, which is the final size of the booklet to be created, using the control panel 20. The electronic control unit 22 acquires the finished size thus input as finished size information. The electronic control unit 22 operates the cutting stopper moving motor 220 to adjust the cutting position of the fore edge and adjusts the cutting position of the top and bottom by operating the top and bottom cutting blade moving motor 222 so that the acquired finished size is obtained. The booklet fed into the three-way cutting mechanism 60 is pressed down by the sheet pressing portion 64 with the leading end positioned by the cutting stopper 62. In this state, the electronic control unit 22 sequentially lowers the small edge cutting blade 66 and the top and bottom cutting blades to cut the three sides of the booklet.

  When the unit attached to the binding unit accommodation unit 44 is not the staple binding unit 96 (N in S26), the electronic control unit 22 determines whether or not the fed sheet is the last sheet of the booklet (S40). When it is the last sheet of the booklet (Y in S40), the electronic control unit 22 presses the uppermost sheet while avoiding transfer of glue to the uppermost sheet stacked on the sheet storage unit 46. (S42), the process proceeds to S32. Specifically, the electronic control unit 22 adjusts the driving pulse supplied to the binding motor 204 to lower the glue cassette 112 to a position where the sheet pressing member 188 presses the sheet but the glue sheet 120 does not contact the sheet. Let Since the sheet pressing member 188 does not directly press the glue transfer position on the lower sheet but presses the periphery thereof, the uppermost sheet may have lower adhesive pressure than other sheets during the binding process. . However, since it is strongly clamped by the pair of folding rollers 52 during the subsequent folding process, it is strongly pressed at this point.

  If it is not the last sheet of the booklet (N in S40), the electronic control unit 22 operates the binding motor 204 to lower the glue cassette 112 and transfer the glue to the uppermost sheet stored in the sheet storage unit 46 ( S44). At this time, the electronic control unit 22 may change the speed and stroke amount of the mounted member 104 up and down depending on whether the unit mounted in the binding unit housing unit 44 is the needle binding unit 96 or the glue binding unit 110. Good. For example, in the staple binding process, it is necessary to lower the pusher 98 at a high speed in order to penetrate the binding needle into the paper. On the other hand, when the glue is transferred to the upper surface of the sheet, a large lowering speed of the mounted member 104 is not required. For this reason, the electronic control unit 22 lowers the mounted member 104 so that the lowering speed of the glue cassette 112 is slower than the lowering speed of the pusher 98 of the needle binding unit 96 by changing the drive pulse supplied to the binding motor 204. You may let them.

  In S42 and S44, the electronic control unit 22 avoids driving the clincher 94 because it is not necessary to bend the leg portion of the binding needle by the clincher 94. When the transfer of glue to the paper is finished, the processing in this flowchart is once finished.

Arranged to do. Specifically, the glue binding unit 110 transfers the glue by pressing the glue sheet 120 against the upper surface of the paper on the upstream side of the position where the binding needle penetrates the paper by the pusher 98 of the needle binding unit 96. In the second embodiment, a clincher 252 and a receiving member 254 are provided instead of the receiving unit 90. The receiving member 254 is provided on the upstream side of the clincher 252, and the receiving member 254 and the clincher 252 do not move in the paper width direction. In this way, the clincher 252 can be easily designed by preventing the clincher 252 from moving in the paper width direction.

  The moving member 250 of the intermediate unit 114 is formed longer in the paper transport direction than the moving member 158 in the first embodiment, and a mounting portion 250a is provided at the downstream end. In the second embodiment, the glue cassette 112 is arranged on the upstream side of the first embodiment. By providing such a long moving member 250, the mounting portion 250a is mounted on the mounted member 104. Thus, it is possible to interlock the elevation of the glue cassette 112 with the elevation of the mounted member 104.

  FIG. 8 is a flowchart illustrating a bookbinding procedure of the bookbinding apparatus according to the second embodiment. The processing in this flowchart is performed by a sheet feeding device until the conveyance of the total number of sheets obtained by multiplying the number of booklets input by the user and the number of sheets constituting one booklet after the start button is pressed by the user is completed. 12 is repeated at every sheet feeding timing.

  The electronic control unit 22 refers to the binding stopper movement flag and the pusher movement flag, and determines whether or not the movement of the binding stopper 42 and the pusher 40 has been completed (S60). When the movements of the binding stopper 42 and the pusher 40 are not completed (N in S60), the electronic control unit 22 uses the detection result of the mounting sensor 106 to determine whether the unit mounted in the binding unit housing unit 44 is stapled. It is determined whether or not the unit 96 (S62).

  When the unit attached to the binding unit housing unit 44 is the needle binding unit 96 (Y in S62), the electronic control unit 22 arranges the binding stopper 42 and the pusher 40 at the position for the needle binding process (S64). . Specifically, the electronic control unit 22 refers to the acquired size information, and the interval between the binding stopper 42 and the pusher 40 is the same as the length in the sheet conveyance direction of the sheet size indicated by the size information, and is accommodated. The binding stopper 42 and the pusher 40 are moved so that the sheet folding line is positioned at the staple position. The staple position is a position where the staple is driven by the staple binding unit 96.

  When the unit attached to the binding unit accommodating portion 44 is not the needle binding unit 96, that is, when the unit is the glue binding unit 110 (N in S62), the electronic control unit 22 sets the binding stopper 42 and the position at the position for the glue binding process. The pusher 40 is arranged (S66). Specifically, the electronic control unit 22 refers to the acquired size information, and the interval between the binding stopper 42 and the pusher 40 is the same as the length in the sheet conveyance direction of the sheet size indicated by the size information, and is stored. The binding stopper 42 and the pusher 40 are moved so that the paper folding line is positioned at the glue binding reference position. The glue binding reference position refers to the center position in the paper transport direction of glue transferred by the glue binding unit 110. When the movement of the binding stopper 42 and the pusher 40 is completed, the electronic control unit 22 sets the binding stopper movement flag and the pusher movement flag to ON. When the movement of the binding stopper 42 and the pusher 40 has been completed (Y in S60), the processing of S62 to S66 is skipped. The processing of S68 to S90 is the same as S22 to S44 in FIG.

Various modifications such as design changes can be added to each embodiment based on the knowledge of those skilled in the art, and embodiments to which such modifications are added can also be included in the scope of the present invention. Here are some examples.

  In a modification, instead of a glue sheet for transferring glue, a glue binding unit that applies liquid glue to a sheet by spraying liquid glue with a glue jet nozzle is used, and this glue binding unit is a binding unit housing portion. 44 is configured to be detachable. In this case, a binding mechanism for pressing around the portion where the liquid glue is attached is provided in the binding unit housing portion 44. The electronic control unit 22 presses the uppermost sheet and presses the lower sheets after the sheet is fed to the uppermost position in the sheet accumulation unit 46 and before or after the glue is applied to the sheet by the glue injection nozzle. Let In this case as well, the electronic control unit 22 controls the ejection of glue so as to avoid the glue from adhering to the upper surface of the last sheet of the booklet. In this way, a booklet using liquid glue can be created by detachably configuring the glue binding unit that uses liquid glue.

  In another variation, the user can input whether the unit attached to the binding unit housing portion 44 is the needle binding unit 96 or the glue binding unit 110 using the control panel 20. When there is an input from the user indicating that it is the needle binding unit 96 that is attached to the binding unit accommodation unit 44, the electronic control unit 22 is the unit that is attached to the binding unit accommodation unit 44 is the needle binding unit 96. Is determined. When there is an input from the user indicating that it is the glue binding unit 110 that is attached to the binding unit accommodation unit 44, the electronic control unit 22 is the unit that is attached to the binding unit accommodation unit 44 is the glue binding unit 110.

  In another variation, the glue binding unit 110 performs a crimping process for pressing the sheets stacked on the sheet storage unit 46 by pressing the uppermost sheet stacked on the sheet storage unit 46. No glue is transferred to the upper surface of the uppermost sheet. In this case, a glue transfer mechanism is provided on the upstream side of the glue binding unit 110 to transfer glue to the upper surface of each sheet fed from the paper feeding device 12. By avoiding the transfer of glue to the paper accumulated in the paper accumulation unit 46 as described above, it is possible to transfer the glue to the upper surface of the paper at a stable location such as on the paper transport plate. Also in this case, instead of using the glue sheet to transfer the glue to the paper, the liquid glue may be ejected and adhered to the paper by the glue jet nozzle.
