Description

  The present invention relates to a gluing device that transfers a glue by pressing a glue sheet to which a glue for transfer is attached to a sheet.

  2. Description of the Related Art Conventionally, as a simple binding method for binding a plurality of sheets in a bookbinding system to form a booklet, a method in which a U-shaped wire is driven and its leading end is bent and bound is widely used. However, when such a method is adopted, it is necessary to devise so that the tip of the wire exposed on the booklet surface does not cause injury. Further, when the booklet is discarded, the wire has to be removed in order to separate the paper and the metal, which requires a complicated operation. In view of this, instead of such a binding method, a bookbinding system was devised in which a gluing device for spraying liquid glue from the nozzles and applying it to the paper surface was devised, but there was a problem that the entire apparatus was large and expensive. In addition, since the adhesive solidifies when exposed to air, there is a problem in maintainability especially when the use is stopped for a long time.

  In order to solve such problems, a new bookbinding system equipped with a gluing device that brings a glue sheet on a long base material sheet into contact with the paper, transfers the glue to the paper, and pastes it. It has been proposed (see, for example, Patent Document 1). In this bookbinding system, the pressing portion is lowered and the glue sheet is pressed against the paper to transfer the glue, and then the pressing portion is raised. Since there is a mechanism for sending the glue sheet in conjunction with the raising and lowering operation of the pressing portion, the glue sheet is automatically fed in conjunction with the glueing operation, and an efficient glueing process is realized.

JP 2007-216677 A

  However, in such a gluing device, in order to ensure the reliability of the subsequent gluing process, the feeding amount of the glue sheet after transfer is set to be slightly larger, and the vicinity of the front end of the non-glued portion is the pressing range by the pressing portion. It was sent to the extent that (transfer area) was exceeded. For this reason, the paste non-transferred portion beyond the transfer region is discarded without being used, and there is a problem that material is wasted. In addition, depending on the type of paper and its target product, it may be necessary to change the transfer length of the glue. To achieve this in the gluing device described in Patent Document 1, a pressing portion having a plurality of types of lengths is prepared. However, this has to be exchanged as necessary, and there is a problem that a complicated operation is required.

  The present invention has been made in view of such problems, and an object of the present invention is to provide a gluing device that can efficiently use the gluing of a gluing sheet for transfer, and more preferably, a gluing size that can be changed by a simple method. It is to provide.

  In order to solve the above-described problems, a gluing device according to an aspect of the present invention is a pressure-receiving surface disposed opposite to a gluing position of a paper in a gluing device for bookbinding in which a part of a glue sheet is pressed against the paper to transfer the glue. And a pressure surface that is disposed opposite the pressure-receiving surface and is pressed against the pressure-receiving surface so as to sandwich the gluing position of the paper when the glue is transferred to the paper, and each time the glue is transferred to the paper, the pressure surface and the pressure-receiving surface. A feeding means for feeding the glue sheet interposed between the two in one direction and stopping so that the boundary between the glue-transferred part and the glue-untransferred part of the glue sheet is included in the pressing range of the pressing surface and the pressure-receiving surface; Is provided.

  The “glue” here means a broad sense of glue and may include various synthetic resin adhesives. For example, the gluing device may constitute a part of a system such as a bookbinding system, in which sheets are sequentially introduced by a predetermined conveyance unit, and the sheet is led out downstream in the conveyance direction after the gluing process. The “pressing range” corresponds to a length range in the feeding direction of the glue sheet in which the pressing surface and the pressure receiving surface are pressed. When the pressing surface is smaller in the feeding direction than the pressure receiving surface, the length range of the pressing surface in the feeding direction can be the pressing range. Conversely, when the pressing surface is larger in the feeding direction than the pressure receiving surface, the length range of the pressure receiving surface in the feeding direction can be the pressing range.

  According to this aspect, when the glue sheet is sent every time the glue is transferred to the paper, the boundary between the glue-transferred part and the glue-untransferred part of the glue sheet (also referred to as “transfer boundary” for convenience) is the pressing surface. It stops so that it may be contained in the press range with a pressure receiving surface, and the next transcription | transfer process is performed in the state. That is, since the amount of glue sheet fed is adjusted so that the tip of the glue non-transferred part following the glue transferred part is always included in the pressing range, the glue on the glue sheet can be used without waste. As a result, the running cost of the glue sheet can be reduced. In order to secure a large transfer width of the glue, the glue sheet may be set so that the transfer boundary is positioned in the vicinity of the front end of the pressing range. In addition, when starting to use for the first time after replacement with a new unused glue sheet, a means for detecting the tip of the glue untransferred portion of the unused glue sheet is provided, and the tip is sent to the pressing range at the start of use. If this is done, the glue on the glue sheet can be used up almost completely.

  Specifically, a guide member having the pressure receiving surface, a pusher having the pressing surface, and a drive mechanism that drives the pusher to advance and retract relative to the guide member may be provided. The feeding means feeds the glue sheet so as to guide the glue sheet along the pressure receiving surface of the guide member while the glue-attaching surface of the glue sheet faces the pusher side, and the drive mechanism moves the sheet between the guide member and the pusher. By driving the pusher in an intervening state and pressing the pressing surface against the pressure receiving surface of the guide member, the portion sandwiched between the pressure receiving surface and the pressing surface of the adhesive adhering surface of the adhesive sheet is brought into contact with the paper to transfer the glue. You may let them.

  In that case, a supply reel on which an untransferred glue sheet is wound, a take-up reel that takes out the transferred glue sheet drawn out from the supply reel and passed through the guide member, and feeds the glue sheet by a predetermined length as a feeding means. On the other hand, a feed mechanism that winds the take-up reel and an actuating mechanism that actuates the feed mechanism as feed means may be provided. The supply reel, guide member, take-up reel, and feed mechanism are housed in a cartridge that can be attached to and detached from the main body of the gluing device separately from the pusher, drive mechanism, and operation mechanism, and the cartridge is fixed to the main body. The pusher may be configured to advance and retract with respect to the guide member.

  According to this aspect, when the glue of the glue sheet is used up, it can be replaced with a new glue sheet in cartridge units, and the replacement work of the glue sheet as a consumable item becomes easy. In addition, since the cartridge itself is fixed to the main body of the gluing device and the pusher is driven to perform the transfer process, it is not necessary to regulate the size of the cartridge in consideration of the durability of the transfer mechanism. That is, in the case of a transfer mechanism that drives the cartridge itself, it is necessary to limit the weight of the cartridge to some extent in consideration of the durability of the transfer mechanism. As a result, the length of the glue sheet incorporated in the cartridge is restricted. However, according to this aspect, since the pusher is driven with the cartridge side fixed, the cartridge can be formed large, and as a result, a long glue sheet can be used, and the cartridge usage period is extended. Can keep. In particular, when the gluing device is applied to a device that automatically performs gluing, such as a bookbinding system, it is possible to reduce the work burden due to frequent replacement of the cartridge.

  You may further provide the feed amount adjustment means which enables adjustment of the feed amount of the glue sheet by a feed means. According to this aspect, the transfer length of the glue, that is, the glue size can be changed by a simple control of adjusting the feed amount of the glue sheet. As a result, a complicated structure in which the size of the pressing surface and the pressure receiving surface can be switched stepwise, and a complicated operation such as switching of the pressing surface and the pressure receiving surface by the operator is not involved.

  Furthermore, a stopper that protrudes onto the paper conveyance path, engages the leading edge of the conveyed paper and positions the paper with respect to the pressure receiving surface, and makes the gluing position of the paper face the pressure receiving surface based on the size information of the paper. And a stopper moving means for moving the stopper in the paper transport direction. Then, the feed amount adjusting means is configured so that the center position in the sheet conveyance direction of the paste non-transferred portion sandwiched between the pressure receiving surface and the pressing surface of the glue sheet coincides with the center position in the sheet conveyance direction of the range to be glued. Position adjustment information for determining the position is sent to the stopper moving means, and the stopper moving means determines the position of the stopper based on the paper size information and the position adjustment information and moves the stopper to the determined position. Good.

  Here, the “paper gluing target range” corresponds to the gluing position of the paper and may be provided at the center position in the length direction of the paper or may be provided at the end of the paper. It can be set as appropriate according to the form of the target product of the paper.

  According to this aspect, even if the feed amount of the glue sheet is changed as described above, the paper transfer of the glue to be transferred is adjusted by adjusting the position of the stopper, that is, the stop position of the paper according to the feed amount. The center position in the direction can be matched with the center position in the sheet conveyance direction of the range to be glued. As a result, the glue can be accurately transferred to the gluing position set on the paper.

  According to the gluing device of the present invention, the paste of the paste sheet for transfer can be used efficiently.

  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 system 10 according to the first embodiment. The bookbinding system 10 includes a paper feeding device 12, a saddle stitch folding device 14, a cutting device 16, a stacker 18, and a management device 20.

  The sheet feeding device 12 includes an A tray 22A and a B tray 22B (hereinafter collectively referred to as “tray 22” as necessary). The tray 22 is loaded with paper on which an image is formed by an image forming method such as printing, electrophotographic method, and ink jet method.

  The sheet feeding device 12 is provided with a sheet feeding control unit 110 having 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. . A separate feeding mechanism 24 is provided for each of the A tray 22A and the B tray 22B. The separation feeding mechanism 24 separates and sends out the uppermost sheet among the sheets stacked on the corresponding tray 22. The separation feeding mechanism 24 employs 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.

  The paper feeder 12 also has a lifting mechanism (not shown) that raises and lowers each of the trays 22 and a paper height sensor (not shown) that detects the height of the paper stacked on each tray 22. . The paper feed control unit 110 stops raising the tray 22 when it is detected that the uppermost paper among the papers stacked on the tray 22 has reached the paper feedable height. In this way, the paper feed control unit 110 maintains the height of the paper stacked on the top of the tray 22 at a paper feedable height, and allows the paper to be continuously fed by the separation and feeding mechanism 24.

  The paper feeding device 12 has a switchback reversing mechanism 26. When the user designates reversal in the management device 20, the switchback reversing mechanism 26 reverses the paper sent out from the A tray 22A and returns it to the paper transport path. The common conveyance path 28 joins the sheet conveyance path for conveying the sheet sent out from the A tray 22A and the sheet conveyance path for conveying the sheet sent out from the B tray 22B.

  The saddle stitch folding device 14 includes a glue transfer mechanism 30 and a folding mechanism 70. The paper sent out from the paper feeding device 12 is sent to the glue transfer mechanism 30 through the common transport path 28 and the paper transport plate 34. Conveying rollers 32 are arranged so as to face each other with the sheet conveying plate 34 interposed therebetween, and the sheet fed onto the sheet conveying plate 34 is conveyed to the glue transfer mechanism 30. The glue transfer mechanism 30 transfers the glue by stopping the fed paper at a specified position. Details of the gluing device constituting the glue transfer mechanism 30 will be described later.

  The glue transfer mechanism 30 is provided with one side guide (not shown) for restricting the movement of the sheet in the sheet width direction, one on the front side and one on the rear side of the apparatus. Each of the pair of side guides has a sheet regulating surface facing each other. In the first embodiment, the pair of side guides is configured to be movable so that the distance from the center in the sheet width direction to the sheet regulating surface is equal by a so-called center distribution method. Each of the pair of side guides is connected to a motor through a gear mechanism, and by operating this motor, it becomes possible to change the distance between the opposed sheet regulating surfaces according to the width of the sheet. ing.

  The saddle stitch folding device 14 is provided with a gluing control unit 112. The gluing control unit 112 includes a CPU, a ROM, and a RAM, and controls the transfer of glue to the paper by controlling the operation of an actuator provided in the glue transfer mechanism 30. The sheet glued by the glue transfer mechanism 30 is conveyed to the folding mechanism 70 by the suction conveyance mechanism 40 and the conveyance roller 42. The suction transport mechanism 40 includes a suction belt, a driving roller, and a suction chamber. The suction belt may be a belt in which a plurality of belts are arranged in parallel in the width direction, or may be a belt in which a plurality of holes are formed in a wide belt. The suction chamber sucks air with a fan provided inside the suction belt, thereby bringing the paper into close contact with the belt. When the suction conveyance mechanism 40 is driven, the paper is conveyed downstream in a manner in which the paper is in close contact with the suction belt.

  The folding mechanism 70 includes a paper conveyance plate 72, a folding stopper 74, a folding knife 76, a folding roller 78, and a belt conveyance mechanism 80. The paper transport plate 72 is provided at a position one level lower than the paper transport plate 34 on the glue transfer mechanism 30 side. Therefore, the plurality of sheets conveyed from the glue transfer mechanism 30 to the folding mechanism 70 are accommodated so as to be stacked on the sheet conveying plate 72 to form a sheet bundle. After the set number of sheets are stacked, the folding mechanism 70 folds the glued sheets while bonding the centers, and conveys the sheets toward the three-way cutting mechanism 90. That is, the folding mechanism 70 simultaneously executes a binding process for binding a plurality of sheets and a folding process for folding the sheet bundle into a booklet.

  The folding stopper 74 is arranged in the vicinity of the end of the sheet conveying plate 72 on the downstream side in the sheet conveying direction (simply referred to as “downstream side”) so as to protrude above the upper surface of the sheet conveying plate 72. The folding stopper 74 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 operates. The sheets sequentially fed from the glue transfer mechanism 30 onto the sheet conveying plate 72 are positioned in the sheet conveying direction when the front end of the sheet abuts against the folding stopper 74. A side guide (not shown) that restricts the position of the paper in the width direction is also provided on the paper transport plate 72. Then, the sheets sequentially stacked at the determined position form a sheet bundle. The folding stopper 74 has been moved in advance in the sheet conveying direction so that the folding line of the sheet bundle is in a position where it abuts against the folding knife 76. In the bookbinding system 10, a direction perpendicular to the paper conveyance direction (referred to as “paper width direction”) is a direction parallel to the folding line.

  Above the paper transport plate 72, a pair of folding rollers 78 are juxtaposed in the paper transport direction so that the axial direction is in the paper width direction. The folding knife 76 is raised between the pair of folding rollers 78 by operating a folding knife drive motor (not shown), and can be lowered below the sheet conveying plate 72. By raising the folding knife 76 in a state where the sheet bundle is positioned in the sheet conveyance direction by the folding stopper 74, the stacked sheets are securely attached, and the sheet bundle is interposed between the pair of folding rollers 78. It is caught and folded.

  The pair of folding rollers 78 is connected to a folding roller drive motor via a gear mechanism or the like. By operating the folding roller driving motor, the pair of folding rollers 78 is driven so as to convey the rolled up sheet bundle while being folded. The booklet folded by the pair of folding rollers 78 is sent to the belt conveyance mechanism 80 through the binding folded booklet conveyance path 82 that extends upward from the nip portion of the pair of folding rollers 78. The belt conveyance mechanism 80 sends the created booklet to the paper conveyance path 92 of the cutting device 16.

  The saddle stitch folding device 14 is provided with a folding control unit 116. The folding control unit 116 includes a CPU, a ROM, and a RAM, and controls the position of the folding stopper 74 in the sheet conveyance direction, the raising and lowering of the folding knife 76, and the driving of the folding roller 78.

  The cutting device 16 has a three-way cutting mechanism 90. The three-way cutting mechanism 90 includes a fore-edge cutting blade 98, a sheet pressing portion 96, a stopper 94, a side guide (not shown), and a pair of top and bottom cutting blades (not shown).

  The stopper 94 can be moved forward and backward in the paper conveyance path 92 by turning on and off a solenoid (not shown). When the booklet edge is cut, the three-way cutting mechanism 90 protrudes the stopper 94 upward from the paper conveyance path 92 before each booklet is fed. The stopper 94 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.

  The booklet conveyed to the three-way cutting mechanism 90 is stopped at the timing immediately after the spine abuts against the stopper 94. The top of the booklet is positioned by a pair of side guides (not shown) before coming into contact with the stopper 94. The sheet pressing portion 96 is lowered toward the booklet in contact with the stopper 94 when a motor (not shown) is operated.

  The fore edge cutting blade 98 is provided above the sheet conveyance path 92 on the upstream side in the sheet conveyance direction (hereinafter referred to as “upstream side”) from the sheet pressing unit 96 and is lowered when a fore edge cutting motor (not shown) is operated. . Each of the top and bottom cutting blades is provided above the paper transport path 92 with the paper pressing portion 96 interposed therebetween, and is lowered by operating a top and bottom cutting motor (not shown). The pair of top and bottom cutting blades can be moved in a direction away from or close to each other by a center distribution method. When a top and bottom cutting blade moving motor (not shown) is operated, the pair of top and bottom cutting blades can be moved to each other via a gear mechanism or the like. Move away or closer.

  By passing between the side guides, the top and bottom positions are aligned, and the sheet pressing portion 96 is lowered and the booklet is pressed while the stopper 94 is positioned in the paper transport direction. In this state, the fore edge cutting blade 98 first cuts the fore edge, and then the pair of top and bottom cutting blades cut the top and the bottom of the booklet. In this way, a final saddle stitch booklet is created. The booklet that has been subjected to the cutting process is conveyed onto the stacker 18. Instead of the three-way cutting mechanism 90, a fork cutting mechanism that cuts only the fore edge may be provided.

  The cutting device 16 is provided with a cutting control unit 118. The cutting control unit 118 includes a CPU, a ROM, and a RAM, and controls the cutting of the booklet by the position of the stopper 94 in the paper conveyance direction, the position of the top and bottom cutting blade in the paper width direction, the small edge cutting blade 98 and the top and bottom cutting blade.

  The management apparatus 20 includes a management PC (Personal Computer) 100, a display 102, a keyboard 104, and a mouse 106. The management PC 100 includes a CPU, a ROM, a RAM, a hard disk, and the like, and is connected to the paper feeding device 12, the saddle stitch folding device 14, and the cutting device 16 so as to be able to transmit and receive data. The display 102, the keyboard 104, and the mouse 106 are connected to the management PC 100.

  The management PC 100 displays a setting screen on the display 102 so that various settings can be input by the user. The user can input various settings using the keyboard 104 and the mouse 106 while the setting screen is displayed. When the user clicks the start button displayed on the display 102, the management PC 100 sends a start signal indicating that the bookbinding process is started together with information indicating the setting contents to the paper feed control unit 110, the gluing control unit 112, and the folding. The data is transmitted to the control unit 116 and the cutting control unit 118.

Here, the detail of the gluing apparatus which makes the principal part of 1st Embodiment is demonstrated. FIG. 2 is a cross-sectional view schematically showing the configuration of the glue transfer mechanism 30.
The glue transfer mechanism 30 includes a glue sheet unit 120, a feed drive mechanism 122, a transfer operation mechanism 124, and a stopper drive mechanism 126.

  The glue sheet unit 120 is disposed above the paper transport plate 34 between the transport roller 32 and the suction transport mechanism 40. A main body casing of a gluing device (not shown) is fixed to the paper transport plate 34, and the glue sheet unit 120 is in the form of a cartridge that is detachably fixed to the main body casing. The glue sheet unit 120 transfers glue to the upper surface of the paper conveyed on the paper conveying plate 34 in cooperation with the transfer operation mechanism 124. In the first embodiment, two glue sheet units 120 are juxtaposed in the paper width direction. The number of glue sheet units 120 is not limited to two. For example, when the paper size is small, one may be used. Of course, for example, when the paper size is large, three or more may be provided.

  FIG. 3 is a cross-sectional view schematically showing the configuration of the glue sheet unit 120. FIG. 4 is a perspective view of the glue sheet unit 120 as viewed from below. FIG. 5 is a perspective view of the glue sheet unit 120 as viewed from above. FIG. 5 shows a state where one side surface of the frame 200 is removed for convenience.

  As shown in FIG. 3, the glue sheet unit 120 includes a frame 200, a supply reel 202, a take-up reel 204, a guide member 206, a feed roller 208, and a near-end detection member 210. One end of the glue sheet 212 is wound around the supply reel 202, and the other end of the glue sheet 212 is wound around the take-up reel 204.

  The supply reel 202 is rotatably attached to one half (the right side in the figure) of the frame 200. The glue sheet 212 is configured by adhering glue to one surface of a flexible long base sheet, and wound around the supply reel 202 so that the glue adhering surface to which the glue is attached is on the outside. It has been turned. By pressing the side of the glue sheet 212 on which the glue is applied to the paper, the glue of the pressed part is peeled off from the base material sheet and attached to the paper. A specific configuration of the glue sheet 212 will be described later.

  The take-up reel 204 is rotatably attached to the upper center of the frame 200, and a take-up gear 214 is fixed so as to rotate coaxially. The guide member 206 is fixed to the lower center of the frame 200. An idler gear 216 that meshes with the winding gear 214 is rotatably provided between the winding gear 214 and the guide member 206. The reduction ratio between the winding gear 214 and the idler gear 216 is set to an appropriate value in consideration of the feed amount of the glue sheet 212. The feed roller 208 is rotatably attached to the half of the frame 200 opposite to the supply reel 202. A guide roller 218 is disposed between the supply reel 202 and the guide member 206, and a guide roller 220 is disposed between the guide member 206 and the feed roller 208. Disc-shaped flanges are provided at both ends in the width direction of the guide roller 220 to restrict the movement of the glue sheet 212 in the width direction.

  The pressure receiving surface 240 at the lower end of the guide member 206 is exposed from the lowermost part of the frame 200, and abuts against the back surface of the adhesive adhesion surface of the adhesive sheet 212 while maintaining a certain tension. The glue sheet 212 drawn from the supply reel 202 is taken up by the take-up reel 204 through the guide member 206, the feed roller 208, and the like, and is guided by the guide rollers 218 and 220 in the process.

  When the take-up reel 204 rotates, the glue sheet 212 wound around the supply reel 202 is drawn out and taken up by the take-up reel 204 via the pressure receiving surface 240 of the guide member 206. The supply reel 202 is fitted on the rotating shaft so as to generate appropriate friction. Even when the glue sheet 212 is wound up by the take-up reel 204, an appropriate tension is maintained in the glue sheet 212.

  A pulley 222 that rotates coaxially is fixed to the feed roller 208, and a pulley 224 that rotates coaxially to the idler gear 216 is also fixed. A rotation transmission belt 226 is stretched between the pulley 222 and the pulley 224, and the rotation of the feed roller 208 is transmitted to the take-up reel 204 through the idler gear 216 and the take-up gear 214. ing. On the other hand, the feed roller 208 is connected to the lever 228 via a one-way clutch (not shown). The lever 228 has a rotation shaft coaxial with the rotation shaft of the feed roller 208 at one end thereof, and the other end extends to the outside of the frame 200. A rotation roller 229 is provided at the other end of the lever 228.

  When the lever 228 rotates in the forward direction (clockwise in the figure), the rotation is transmitted to the feed roller 208 via the one-way clutch. Then, the rotation of the feed roller 208 is transmitted to the take-up reel 204 via the belt 226, the idler gear 216 and the take-up gear 214. As a result, the glue sheet 212 is fed by the rotation of the feed roller 208 and the glue sheet 212 is wound by the rotation of the take-up reel 204. On the other hand, even if the lever 228 rotates in the reverse direction (counterclockwise in the figure), the rotation is not transmitted to the feed roller 208 by the one-way clutch. Accordingly, the glue sheet 212 once taken up by the reverse rotation of the feed roller 208 and the take-up reel 204 is not loosened.

  The rotation of the lever 228 is realized by a feed driving mechanism 122 (see FIG. 2) installed outside the glue sheet unit 120. That is, the feed drive mechanism 122 includes a rotary shaft 130 rotatably attached to the main body casing of the gluing device, an eccentric cam 132 fixed to the rotary shaft 130, and a feed drive motor (not shown) that rotationally drives the rotary shaft 130. It is comprised including. The number of eccentric cams 132 corresponding to the plurality of glue sheet units 120 (two in the first embodiment) is provided, and each of the eccentric cams 132 is disposed at a position corresponding to the lever 228 of each glue sheet unit 120. The outer circumferential surface of the eccentric cam 132 is in contact with the rotating roller 229 of the lever 228 and supports the lever 228 from below. The lever 228 is biased by a spring (biasing member) (not shown) so that the rotating roller 229 contacts the eccentric cam 132. Each time the eccentric cam 132 rotates once, the lever 228 reciprocates once. The one-time feed amount of the glue sheet 212 is determined by the rotation angle of the lever 228.

  In order to adjust the feed amount of the glue sheet 212, a feed amount adjustment cam 230 is provided below the lever 228. The feed amount adjusting cam 230 is rotatably provided on an eccentric shaft 232 attached to the frame 200, and restricts the rotation range of the lever 228 by contacting the lever 228. In the first embodiment, the feed amount adjusting cam 230 is manually rotated by the operator so that the bottom dead center of the rotation of the lever 228 can be adjusted. Thus, by changing the rotation range of the lever 228, the rotation amount of the feed roller 208 changes, and as a result, the feed amount of the glue sheet 212 changes.

  Further, a driven roller 234 is provided so as to sandwich the glue sheet 212 with the feed roller 208. The driven roller 234 is made of an elastic body such as rubber and is urged toward the feed roller 208 by a spring 236 to apply an appropriate frictional force to the glue sheet 212 to assist the glue sheet 212 to be stably fed. .

  As shown in FIGS. 2 and 3, the guide member 206 has a rectangular pressure receiving surface 240 extending in the paper width direction on the lower surface thereof, and abuts against the back surface of the glue sheet 212 at the pressure receiving surface 240. A peeling member 242 is disposed below the guide member 206. As shown in FIGS. 4 and 5, the peeling member 242 is obtained by molding a metal plate material, and has a large slit 244 in a rectangular plate-shaped main body. From the slit 244, the pressure receiving surface 240 of the guide member 206 and the glue sheet 212 are exposed downward. The peeling member 242 is provided with pressing surfaces on both sides of the guide member 206 in the width direction, and the pressing surface is provided on the upstream side of the guide member 206 in the sheet conveying direction over the entire width.

  The peeling member 242 is for peeling off the paper attached to the glue sheet 212 after the transfer process to the paper is performed. A fulcrum shaft 246 is detachably fitted in a slit (not shown) opened toward the upstream side of the peeling member 242 on the upstream side in the sheet conveyance direction (simply referred to as “upstream side”). A support shaft 248 and a fulcrum shaft 246 are detachably fitted into a slit 245 opened toward the downstream side at the end of the peeling member 242 on the downstream side in the sheet conveying direction (simply referred to as “downstream side”). ing. Both ends of the fulcrum shaft 246 are respectively supported by slits 250 formed on opposite side surfaces of the frame 200. The slit 250 extends in the lateral direction and is inclined so that the downstream end is slightly lower than the upstream end. A spring 252 is attached to each end of the fulcrum shaft 246 protruding from the slit 250. The other end of the spring 252 is fixed to the frame 200 on the downstream side of the slit 250.

  In the state shown in the drawing, the fulcrum shaft 246 is fitted so as to be pressed against the upstream slit of the peeling member 242 by the urging force of the spring 252, and the downstream slit 245 of the peeling member 242 is pressed against the support shaft 248. Are fitted. For this reason, the peeling member 242 is stably supported by the fulcrum shaft 246 and the support shaft 248. When the fulcrum shaft 246 is moved away from the peeling member 242 against the urging force of the spring 252 from this state, the fitting between the peeling member 242 and the fulcrum shaft 246 is released. And if the peeling member 242 is moved further upstream, the fitting between the peeling member 242 and the support shaft 248 can be removed, and the peeling member 242 can be detached from the frame 200. Thereby, the installation or replacement of the glue sheet 212 in the frame 200 can be easily performed.

  A leaf spring 253 having a predetermined width is provided so as to extend from the downstream side wall of the frame 200 toward the upper surface of the support shaft 248. The leaf spring 253 biases the peeling member 242 downward, that is, away from the guide member 206 via the support shaft 248.

  On the other hand, both ends of the support shaft 248 are also supported by slits 254 formed on opposite sides of the frame 200, respectively. The slit 254 extends in the vertical direction, and allows the support shaft 248 to be displaced in the vertical direction. At each tip of the support shaft 248 projecting from the slit 254, a falling-off disc 256 is attached. The width of the slit 244 is set to be slightly larger than the length of the pressure receiving surface 240 positioned above and smaller than the width of the paper fed downward. The peeling member 242 is positioned at the bottom dead center in the drawing by the urging force of the leaf spring 253 in the standby state, but is pushed upward together with the paper disposed on the lower surface when the transfer operation mechanism 124 is operated. That is, the peeling member 242 is pushed upward in a manner of rotating about the fulcrum shaft 246 in the transfer process, but when the transfer process is completed, the peeling member 242 is pushed downward by the urging force of the leaf spring 253 and returns to the standby position. . In that process, the paper adhered to the glue sheet 212 is surely and quickly peeled off.

  The near-end detection member 210 has a rotation shaft 260 provided in the vicinity of the lower end corner of the frame 200 and a detection lever 262 that rotates about the rotation shaft 260. The detection lever 262 includes an arm portion 264 that extends from the rotation shaft 260 toward the supply reel 202, and a detection portion 266 that extends from the rotation shaft 260 to the opposite side of the arm portion 264. A roller 268 is provided at the tip of the arm portion 264. A spring 270 is interposed between the lower end portion of the detection lever 262 and the frame 200, and urges the detection lever 262 toward the supply reel 202, that is, clockwise in the drawing. For this reason, the roller 268 always maintains a state in which the roller 268 is in contact with the outer peripheral surface of the glue sheet 212 wound around the supply reel 202.

  As the glue sheet 212 of the supply reel 202 is consumed and decreased, the arm portion 264 rotates in the direction of the arrow in the figure. As a result, when the glue-untransferred portion of the glue sheet 212 approaches the near-end where there is little remaining, the detection unit 266 protrudes from the frame 200 as shown, and the optical sensor 272 (see FIG. 2) installed outside the frame 200 To detect. The optical sensor 272 is configured as a transmissive sensor having a light emitting element that emits light and a light receiving element that receives light reflected by the conveyed paper, and the light emitting element and the light receiving element are two glue sheets. Oppositely arranged near the upstream end of the unit 120. Then, when the near-end detection member 210 of any glue sheet unit 120 blocks the light, the occurrence of near-end is detected. In the modification, a reflective sensor may be employed as the optical sensor 272, and the near-end detection member 210 of any glue sheet unit 120 may reflect the light to detect the near-end. .

  When the near end is detected in this manner, the winding process of the glue sheet 212 and the entire bookbinding process are temporarily stopped. The optical sensor 272 is installed as a sensor common to a plurality of glue sheet units 120 (two in the first embodiment), and is detected when one of the glue sheet units 120 becomes near-end. That is displayed on the display 102. The operator sees the display and replaces the glue sheet unit 120 that has become near-end by visually confirming the display. In the modification, an optical sensor or the like may be provided corresponding to each glue sheet unit 120 to explicitly notify which glue sheet unit 120 has become near-end.

  The stopper driving mechanism 126 includes a stopper 290 and its driving mechanism 292. The stopper 290 is provided in parallel with the suction conveyance mechanism 40, and engages the leading edge of the conveyed paper P to position the paper P at the time of glue transfer. The drive mechanism 292 includes a stopper drive solenoid and a spring that project or retract the stopper 290 on the upper surface of the paper transport plate 34 (transport path), and a stopper movement motor that moves the stopper 290 in the paper transport direction. The paper P sequentially fed from the paper feeding device 12 side is positioned in the paper transport direction when the front end of the paper P comes into contact with the stopper 290.

  The transfer operation mechanism 124 includes a pusher 280 and its drive mechanism 282. The pusher 280 has a pressing surface 284 facing the pressure receiving surface 240 of the guide member 206 at its upper end, and has a rectangular shape extending in the paper width direction. The pressing surface 284 is sufficiently larger than the pressure receiving surface 240 in the paper transport direction. For this reason, the pressing range by the pressing surface 284 and the pressure receiving surface 240 corresponds to the size of the pressure receiving surface 240 side. Further, the width of the peeling member 242 is larger than the width of the slit 244 in the paper width direction. For this reason, when the pusher 280 is raised, the peeling member 242 is pushed from below and raised. The pusher 280 has at least the pressing surface 284 and its vicinity formed of an elastic material so that the pressing surface 284 can be in close contact with the paper.

  The drive mechanism 282 includes a pusher drive solenoid that applies a force in a direction to bring the pusher 280 close to the guide member 206 and a spring that applies a biasing force in a direction to move the pusher 280 away from the guide member 206. In the glue transfer process, the pusher drive solenoid is energized, and the pusher 280 is driven to the guide member 206 side by the suction force. At this time, the pusher 280 is pressed against the pressure receiving surface 240 after the pressing surface 284 pushes up the paper P and the peeling member 242 by a predetermined height. At this time, the adhesive sheet 212 is pressed between the pressure receiving surface 240 and the pressing surface 284 to the adhesive position of the paper P, and the adhesive is transferred.

  When the glue transfer process is completed, the power supply to the pusher drive solenoid is turned off, and the pusher 280 returns to the original standby position by the biasing force of the spring. At this time, the peeling member 242 also returns to the standby position, which is the bottom dead center, by the urging force of the leaf spring 253, and the paper P is peeled off from the glue sheet 212 in the process.

Next, the detail of the gluing method of 1st Embodiment is demonstrated.
FIG. 6 is a partially enlarged view showing details of the glue sheet 212. (A) shows one example, (B) shows another example, and (C) shows a comparative example that is not adopted in the first embodiment. The vertical direction in the figure is the longitudinal direction (feeding direction) of the glue sheet 212.

  The glue sheet 212 is formed by arranging a large number of circular dot-like glue segments 302 on one side of a long base sheet 300 having peelability. The glue segment 302 is formed such that the arrangement direction (see the alternate long and short dash line) connecting the glue segments closest to each other in the base sheet 300 is inclined with respect to the longitudinal direction. Here, “tilt” means a state that is neither parallel nor perpendicular. FIG. 2A shows an example in which the closest adhesive segments form a triangular lattice. FIG. 4B shows an example in which the closest adhesive segments form a square lattice.

  In both of the embodiments shown in FIGS. 4A and 4B, the arrangement directions of the closest glue segments are inclined, so even the glue segments 302 arranged in the same arrangement direction are within the transfer range ( Whether or not it is transferred depends on whether or not it is substantially present in the two-dot chain line). If transfer is performed when the area within the transfer range is larger than the area outside the transfer range, the same glue segment 302 is transferred in both the continuous transfer ranges a and b. In the figure, for convenience of explanation, one glue segment 302 is greatly exaggerated, but if its size is set appropriately, its uniformity can be improved. In the first embodiment, since the pressing surface 284 of the pusher 280 is sufficiently larger than the pressure receiving surface 240 of the guide member 206, the end boundary e on the upstream side in the sheet conveying direction of each transfer range is It coincides with the end edge line on the upstream side of the pressure receiving surface 240 (see the end edge line 241 in FIG. 7). That is, the arrangement direction of the closest adhesive segments is also inclined with respect to the end boundary line e, that is, the end ridge line on the upstream side of the pressure receiving surface 240.

  On the other hand, in the comparative example of FIG. 6C, the arrangement direction of the closest glue segments is not inclined, so that the number of glue segments 302 in the transfer range a is as shown in the figure. There are more cases where the number is larger than 302. For this reason, the transfer length of the glue for each transfer may be non-uniform. In other words, as in the first embodiment, by tilting the arrangement direction of the glue segments, it is possible to improve the cutting of the glue, and as a result, the amount is almost equal to the feed amount of the glue sheet. The paste can be transferred, and the quality of the glued portion of the paper can be kept good.

FIG. 7 is a diagram schematically illustrating the glue transfer process.
In the first embodiment, the transfer method is devised so that the paste sheet 212 can be consumed efficiently without waste. That is, when the process proceeds to the transfer process, the boundary (referred to as “transfer boundary”) 314 between the glue-transferred portion 310 and the paste-untransferred portion 312 of the glue sheet 212 is a pressing range A between the pressing surface 284 and the pressure receiving surface 240. In this state, the next transfer process is performed. In the first embodiment, since the pressure receiving surface 240 is configured to be smaller than the pressing surface 284, the pressing range A is substantially equal to the width of the pressure receiving surface 240. That is, the pressing range A is a region sandwiching the upstream end ridge line 241 and the downstream end ridge line 243 of the pressure receiving surface 240. However, in order to secure the transfer length l of the glue, the transfer boundary 314 is set in the vicinity of the downstream end of the pressure receiving surface 240 (in the vicinity of the end ridge line 243). Thus, by setting the transfer boundary 314 within the pressing range A, the glue sheet 212 can be used without waste.

  The glue transfer length l can be changed by adjusting the glue feed amount by the feed amount adjusting cam 230. At this time, the transfer boundary 314 in the pressing range A moves. In the first embodiment, in order to ensure the accuracy of the gluing position with respect to the paper P, the position of the stopper 290 is such that the center position of the glue transfer portion (see the alternate long and short dash line) is located at the center of the paper P in the paper conveyance direction. Adjustments are made. In the first embodiment, a position sensor (position detecting means) (not shown) for detecting the rotation phase of the feed amount adjusting cam 230 (see FIG. 2) is provided, and the position sensor rotates the position (position) of the feed amount adjusting cam 230. Adjustment information) is detected. The management PC 100 calculates the rotation angle of the lever 228 from the rotation position, and hence the feed amount of the glue sheet 212, and calculates the transfer length l from the feed amount. The management PC 100 holds the upstream end position (upstream edge position) of the guide member 206 in advance, and sets the position away from the upstream end position by a distance of 1/2 of the transfer length l. It can be calculated as the center position of the transfer portion. From the calculated center position of the glue transfer portion and the size information of the paper P, the stop position of the stopper 290 is determined so that the center position of the glue transfer portion is located at the center of the paper P in the paper transport direction. Can do.

  FIG. 8 is a functional block diagram of the bookbinding system 10. In FIG. 8, functional blocks realized by cooperation of hardware such as CPU, ROM, RAM, and software are depicted. Therefore, these functional blocks can be realized in various forms by a combination of hardware and software.

  The management PC 100 includes a size information acquisition unit 150 and a fold line setting unit 152. The size information acquisition unit 150 acquires size information including information indicating the conveyance direction length of the sheet and information indicating the width direction length in the sheet width direction. The size information acquisition unit 150 may acquire information indicating the paper size input or selected by the user as size information. For example, when a paper size sensor is provided in the tray 22, the detected paper size may be acquired as size information.

  The fold line setting unit 152 sets a fold line on the paper using the acquired size information. Specifically, the folding line setting unit 152 uses the information indicating the length in the transport direction of the paper included in the acquired size information, and is at a distance half the length in the transport direction from the leading edge of the paper to be transported. Set a straight line as a 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 fold line setting unit 152 may set a straight line at a distance from the front end of the paper input by the user as the fold line.

  The sheet feeding control unit 110 is connected to a solenoid that switches between suction and stop of air in the separation feeding mechanism 24 and a motor that drives a roller that meshes with the conveyance belt. The sheet feeding control unit 110 controls the feeding of the sheet from the sheet feeding device 12 by switching between air suction and suction stop while the transport belt is driven.

  The gluing control unit 112 is connected to a pusher drive solenoid 154, a stopper drive solenoid 156, a stopper movement motor 158, a feed drive motor 160, and a transfer interval adjustment motor 162. Based on the paper size information and the folding line position information, the gluing control unit 112 calculates the paper transport position so that the paper gluing position is positioned on the folding line. Also, based on the center position of the glue transfer portion calculated based on the adjusted feed amount information and the paper size information, the center position of the glue transfer portion is positioned at the center of the paper in the paper transport direction. The stop position of the stopper 290 is determined. Then, the stopper drive solenoid 156 is energized to cause the stopper 290 to protrude onto the paper transport plate 34, and the stopper moving motor 158 is driven to move the stopper 290 to the paper transport tip position. Further, each time the glue transfer process is completed, the feed drive motor 160 is driven to rotate the eccentric cam 132, and the glue sheet 212 is fed by a predetermined amount. That is, as described above, the glue sheet 212 is fed so that the transfer boundary 314 stops at the set position within the pressing range.

  The gluing control unit 112 operates the pusher drive solenoid 154 to raise the pusher 280 when the conveyance of the paper is stopped, thereby transferring the glue to the upper surface of the paper. The gluing control unit 112 also outputs a drive pulse to the transfer interval adjustment motor 162 to adjust the interval between the plurality of glue sheet units 120, that is, the interval between the glue transfer locations on the paper by the glue sheet unit 120. The gluing control unit 112 also controls the driving of the suction conveyance mechanism 40 in order to convey the paper, for which the gluing process has been completed by the gluing transfer mechanism 30, to the folding mechanism 70 side.

  The folding control unit 116 is connected to a stopper moving motor 164 that moves the folding stopper 74 in the transport direction, a folding knife drive motor 166 that moves the folding knife 76 up and down, and a folding roller drive motor 168 that drives the folding roller 78. The folding control unit 116 moves the folding stopper 74 to a predetermined position before the sheet is fed from the glue transfer mechanism 30 side to the folding mechanism 70. As a result, the sheets are sequentially stacked while abutting and engaging with the folding stopper 74 to form a sheet bundle. Thereafter, the folding control unit 116 operates the folding knife driving motor 166 and the folding roller driving motor 168 to raise the folding knife 76 to bind the stacked sheets, and hold the sheet bundle between the folding rollers 78 to fold the booklet. Create

  The management PC 100 acquires the finished size input by the user as finished size information. Note that the management PC 100 may acquire a size obtained by further subtracting the cutting margin from the size obtained by folding the paper of the size indicated by the paper size information acquired by the size information acquisition unit 150 in half, as the finished size of the booklet. . The management PC 100 transmits the acquired finish size information to the cutting control unit 118.

  The cutting control unit 118 is connected to the stopper moving motor 170 and the top and bottom cutting blade moving motor 172. The cutting control unit 118 specifies the cutting position of the fore edge and the cutting position of the top and bottom based on the received finish size information. The cutting control unit 118 operates the stopper moving motor 170 to move the stopper 94 so as to cut the fore edge at the specified position. The cutting control unit 118 operates the top and bottom cutting blade moving motor 172 to move the top and bottom cutting blades so as to cut the top and bottom at the specified position.

  FIG. 9 is a flowchart showing the bookbinding procedure of the bookbinding system 10. 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 management PC 100 transmits a signal indicating the paper feed timing to the paper feed control unit 110 so that the bookbinding process proceeds smoothly in the saddle stitch folding device 14 and the cutting device 16. Upon receiving a signal indicating the paper feed timing, the paper feed control unit 110 performs a paper feed process for feeding one sheet from the tray 22 (S14).

  The management PC 100 transmits information indicating whether or not the sheet is the last sheet of the booklet to the gluing control unit 112 at the timing when the sheet is sent to the glue transfer mechanism 30. Based on the information, the gluing control unit 112 determines whether or not the sheet to be fed is the last sheet in the booklet (S16).

  When it is determined that the booklet is not the final sheet (N in S16), the gluing control unit 112 stops the suction conveyance mechanism 40 and drives the stopper 290 to adjust it to the set position (S30). As a result, the position in the sheet conveyance direction where the pressure receiving surface 240 of the guide member 206 is pressed is set as the gluing position, and the sheet is stopped so that the folding line is positioned at the gluing position. When the paper stops, the glue control unit 112 raises the pusher 280 to transfer the glue to the upper surface of the paper (S32). By transferring the glue in a state where the fold line is positioned at the gluing position in this way, gluing can be performed around the fold line.

  At this time, the folding control unit 116 adjusts the position of the folding stopper 74 so that the pasting position of the sheet conveyed thereafter is positioned at the folding line (S34). When the transfer process is completed, the gluing control unit 112 drives the suction conveyance mechanism 40 after retracting the stopper 290 to the standby position, and conveys the sheet on which the glue is transferred to the folding mechanism 70 (S36). In this way, the sheets are sequentially stacked on the sheet conveying plate 72 of the folding mechanism 70.

  If it is determined that the booklet is the final sheet (Y in S16), the glue control unit 112 avoids glue transfer (S18) and transports the final sheet to the folding mechanism 70 (S20). Thus, by not gluing the final sheet of the booklet to the sheet, it is possible to avoid gluing on the upper surface of the sheet bundle before the folding process.

  The folding control unit 116 raises the folding knife 76 at the timing when the final sheet is conveyed and the sheet bundle is formed, and the sheet bundle is sandwiched between the folding rollers 78 to be folded. At this time, the folding knife 76 comes into contact with the folding line to which the glue has been transferred, and further, this portion is sandwiched between the folding rollers 78, so that the portions to which the glue has been transferred are pressed against each other and bonded together ( S22). The saddle stitched booklet created by folding is sent to the cutting device 16. The cutting control unit 118 performs a cutting process for cutting three sides of the sent booklet (S24). The saddle-stitched booklet created in this way is stacked on the stacker 18.

(Second Embodiment)
FIG. 10 is a diagram illustrating a configuration example of a bookbinding system 400 according to the second embodiment. Hereinafter, the same parts as those in the bookbinding system 10 according to the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

  The bookbinding system 400 includes a collation device 410, a saddle stitch folding device 414, a cutting device 16, and a management device 20. The collating device 410 functions as a paper feeding device that feeds paper out of the paper container. Specifically, the collating apparatus 410 includes a main body part 430 and a transport part 432. The main body 430 includes a plurality of paper feed trays 434 (10 in the second embodiment) that are paper storage units, a paper feed mechanism 436 provided for each of the paper feed trays 434, and a common transport path. 438.

Corresponding to each of the paper feed trays 434, a lifting mechanism (not shown) for raising and lowering the paper feed tray 434, and a paper height for detecting the height of the uppermost paper among the papers stacked on the paper feed tray 434 A sensor (not shown) is provided. The height of the sheet feed tray 434 is adjusted by the elevating mechanism so as to maintain the height of the uppermost sheet detected by the sheet height sensor.

  The paper feed mechanism 436 separates and sends out the uppermost paper among the papers stacked on the paper feed tray 434. The paper feeding mechanism 436 is an air suction type. Since the air suction type paper feeding device is known, its detailed description is omitted. Needless to say, a so-called friction type paper feeding device may be provided instead of the air suction type paper feeding device. The common conveyance path 438 is provided so as to extend in the vertical direction, and the sheet fed from the sheet feeding tray 434 by each of the sheet feeding mechanisms 436 is conveyed downward through the common conveyance path 438.

  The collating device 410 is provided with a paper feed control unit 422 that controls the paper feed operation by the paper feed mechanism 436. The paper feed control unit 422 adjusts the paper feed timing of the paper feed mechanism 436 so that the papers fed from the plurality of paper feed trays 434 are overlapped and conveyed, or the papers alone are not overlapped with other papers. Control the paper conveyance. The transport unit 432 transports the paper transported from the main body unit 430 upward.

  The saddle stitch folding device 414 includes a binding device 450, a folding device 480, and a folding reinforcement device 482. The binding device 450 has a crimping process for crimping and binding a plurality of sheets arranged in a predetermined position in a superposed state when at least one of adjacent sheets is glued, and driving a binding needle. And the needle binding process of binding in the above are alternatively executed.

  Specifically, the binding device 450 includes a device mounting portion 452, a mechanism housing portion 454, a belt transport mechanism 456, a stopper 458, and a bag jogger 460. The belt transport mechanism 456 transports paper placed on the top surface of the transport belt. The stopper 458 is provided so as to be able to advance above the upper surface of the conveyor belt in the belt conveyor mechanism 456. The bag jogger 460 presses the trailing edge of the paper stacked on the upper surface of the conveying belt of the belt conveying mechanism 456 toward the downstream side, thereby pressing the leading edge of the paper against the stopper 458 to align the edge of the paper. Since the configurations of the belt transport mechanism 456, the stopper 458, and the bag jogger 460 are known, detailed description thereof is omitted.

  The device mounting portion 452 is provided with a gluing device, which will be described later, and a collating device 410 that sends out paper from the paper storage portion and superimposes a plurality of papers and carries them out to the binding device 450 so that they can be attached alternatively. . Specifically, the device mounting portion 452 has a common mounting mechanism that can mount both the gluing device and the collating device 410. Note that a mounting mechanism for mounting the gluing device and a mounting mechanism for mounting the collating device 410 may be provided separately.

  In addition, the binding mechanism housing portion 454 is provided so that a crimping mechanism, which will be described later, and a needle binding mechanism 470 that executes a needle binding process can be alternatively mounted. The gluing device is provided so as to allow gluing to the paper. The crimping mechanism is provided so that a crimping process can be performed. By providing the apparatus mounting portion 452 and the mechanism housing portion 454 as described above, it is possible to realize the bookbinding system 400 that can alternatively execute the glue binding processing for gluing and pressing the paper and the needle binding processing. . FIG. 10 illustrates the bookbinding system 400 when the collation device 410 is attached to the device attachment portion 452 and the needle binding mechanism 470 is attached to the mechanism housing portion 454.

  The saddle stitch folding device 414 is provided with a binding control unit 424 that controls the operation of the binding device 450. The binding control unit 424 controls the operation of the crimping mechanism when the mechanism housing unit 454 is mounted, and controls the operation of the needle binding mechanism 470 when the needle binding mechanism 470 is mounted.

  The folding device 480 folds the paper loaded from the binding device 450 at the center and conveys it as a half-fold booklet. The folding device 480 is provided with a pair of belt conveyance mechanisms 484 in place of the paper conveyance plate 72, and is arranged so as to be inclined so as to move downward on the whole as a whole. The configuration is the same as that of the mechanism 70. The booklet folded and created by the folding device 480 is conveyed to the folding strengthening device 482 by the belt conveyance mechanism 80.

  The folding strengthening device 482 is provided so as to sandwich the back portion of the booklet again in order to suppress the swelling of the half-folded booklet folded by the folding device 480. Since the configuration of the folding strengthening device 482 is known, detailed description thereof is omitted. A paper sensor 490 is provided on the upstream side of the folding strengthening device 482. The belt conveyance mechanism 80 temporarily stops the conveyance of the booklet at a timing at which a predetermined time has elapsed after the back of the sent booklet is detected by the paper sensor 490 so that the back can be clamped by the folding strengthening device 482. The folding reinforcement device 482 presses the back of the booklet that has been temporarily stopped.

  The saddle stitch folding device 414 is provided with a folding control unit 426. The folding control unit 426 controls the operations of the folding device 480 and the folding strengthening device 482 to execute a folding process for folding a sheet to create a center folded booklet. The created booklet is carried out to the cutting device 16 and then subjected to a cutting process.

  Each of the paper feed control unit 422, the binding control unit 424, the folding control unit 426, and the cutting control unit 118 is connected to the management PC 100. The management PC 100 functions as a system control unit 420 that gives commands to these control units so as to appropriately control each device.

  As shown in FIG. 10, when the collating device 410 is mounted on the device mounting portion 452 and the needle binding mechanism 470 is mounted on the mechanism housing portion 454, the user clicks the bookbinding process start button in the management device 20. Then, the collating device 410 first superimposes a plurality of sheets and carries them out to the binding device 450. The binding device 450 is a belt conveyance mechanism that moves a position of the stopper 458 in the paper conveyance direction before carrying in the paper so that the binding needles are driven into the center in the conveyance direction for a plurality of papers carried in a superimposed state. 456 is disposed on the conveyor belt. Next, the needle binding mechanism 470 executes a needle binding process on the plurality of sheets.

  The plurality of sheets thus subjected to the staple binding process are folded by the folding device 480 and the folding strengthening device 482, and the three sides are cut by the cutting device 16 and are accumulated in the stacker 18 as a saddle stitched booklet. Note that only the fore edge or the top and bottom may be cut by the cutting device 16.

  FIG. 11 is a diagram illustrating another configuration example of the bookbinding system 400 according to the second embodiment. FIG. 11 illustrates a bookbinding system 400 in which the gluing device 500 is mounted on the device mounting portion 452 and the crimping mechanism 510 is mounted on the mechanism housing portion 454. The operation of the gluing device 500 is controlled by the gluing control unit 504.

  The gluing device 500 has a glue transfer mechanism 30 and a paper reversing mechanism 502, and glues the paper carried in from the collating device 410 and carries it out to the binding device 450. When there is a paper reversal request, the paper reversing mechanism 502 reverses the paper transported by the suction transport mechanism 40 and carries it out to the saddle stitch folding device 414. Note that the configuration of the sheet reversing mechanism 502 is well known, and thus the description thereof is omitted.

  The crimping mechanism 510 includes a pusher 512 and a cradle 514. The crimping mechanism 510 has a lifting mechanism (not shown) provided with a cam mechanism and a motor. By operating this motor, the pusher 512 moves up and down via the cam mechanism.

  The crimping mechanism 510 operates the lifting mechanism to push the uppermost sheet downward by the pusher 512 when the last sheet among the sheets included in one booklet is stacked. As a result, the sheets stacked on the transport belt are sandwiched and pressed by the pusher 512 and the receiving tray 514.

  FIG. 12 is a perspective view showing the shape of the pusher 512. The pusher 512 is formed in a square plate shape. The pusher 512 is disposed above the belt conveyance mechanism 456 so as to extend in the vertical direction. On the lower surface of the pusher 512, a pressing surface 512a for pressing the paper is formed.

  A recess extending in the paper width direction may be formed at the center of the pressing surface 512a. By forming such a recess, it is possible to press the periphery of the paper while avoiding pressing the pusher 512 to the glue transfer location on the upper surface of the paper. Note that the pressing surface 512a of the pusher 512 may be subjected to a process in which glue is difficult to transfer, such as a fluororesin coating process or a fluororesin-containing nickel plating process. As a result, the pusher 512 can be directly pressed against the glue transfer portion of the paper.

  Returning to FIG. When the gluing device 500 is mounted on the device mounting portion 452 and the crimping mechanism 510 is mounted on the mechanism housing portion 454, when the user clicks the bookbinding start button in the management device 20, the collating device 410 First, each of a plurality of sheets included in a booklet to be created is carried out one by one to the gluing device 500 without being overlaid. Next, the gluing device 500 applies a gluing process to each sheet so that when a plurality of sheets included in the booklet to be created are overlapped, at least one of the adjacent sheets can be glued. Specifically, the gluing device 500 avoids the transfer of the glue only for the paper that is finally transported to the binding device 450 among the plurality of papers included in the booklet, and the pusher 280 is raised and glued to the other paper. The sheet is pressed against the glue sheet 212 of the sheet unit 120, and the glue is transferred to the upper surface thereof. At this time, the gluing device 500 adjusts the gluing position on the paper so as to transfer the gluing to the center in the paper transport direction by controlling the stop position of the paper.

  The binding device 450 moves the position of the stopper 458 in the paper conveyance direction before carrying in the paper, thereby conveying each conveyed paper so that the pusher 512 can press the center in the conveyance direction by the belt conveyance mechanism 456. Load on the belt. The crimping mechanism 510 performs a crimping process on the plurality of sheets stacked in this way. The plurality of sheets subjected to the glue binding process are folded by the folding device 480 and the folding strengthening device 482, and three sides are cut by the cutting device 16 and accumulated in the stacker 18 as a saddle stitch folded booklet.

  The binding device 450 includes a mechanism detection sensor 462 that detects which one of the crimping mechanism 510 and the needle binding mechanism 470 is attached to the binding mechanism housing 454. The mechanism detection sensor 462 is configured by a switch that is turned on by a protrusion provided on the crimping mechanism 510 only when the crimping mechanism 510 is mounted. Note that another type of switch may be employed for the mechanism detection sensor 462. The binding control unit 424 controls the crimping mechanism 510 or the needle binding mechanism 470 attached to the binding mechanism storage unit 454 based on the detection result of the mechanism detection unit. Specifically, in the second embodiment, the needle binding mechanism 470 and the crimping mechanism 510 are driven by a common motor (not shown) and a driver and a pusher 512 for driving the binding needle, respectively.

  For example, when the attachment of the needle binding mechanism 470 to the mechanism housing unit 454 is detected, the binding control unit 424 transports a plurality of sheets onto the transport belt of the belt transport mechanism 456 and aligns the end by the bag jogger 460. The driver is driven by operating the motor so that the binding needle is driven immediately after being received. For example, when the attachment of the pressure-bonding mechanism 510 to the mechanism housing unit 454 is detected, the binding control unit 424 activates the motor at a timing when the sheets are fed one by one onto the conveyance belt of the belt conveyance mechanism 456. Then, the pusher 512 is driven. By providing the mechanism detection sensor 462 in this manner, the pressure bonding process or the needle binding process can be appropriately executed regardless of which mechanism is mounted on the mechanism housing portion 454.

  The management device 20 is provided so that the user can select the needle binding mode and the glue binding mode. The system control unit 420 acquires the mode selection request input by the user in this way. For example, when the selection of the glue binding mode is acquired despite the detection of the attachment of the needle binding mechanism 470 to the mechanism housing unit 454, the system control unit 420 displays a warning on the display 102 to the user. This is notified and the transition to the glue binding mode is avoided. At this time, the system control unit 420 disables various setting inputs to the management apparatus 20 by the user for executing the glue binding process.

  For example, when the selection of the stitch binding mode is acquired even though the attachment of the crimping mechanism 510 to the mechanism housing unit 454 is detected, the system control unit 420 displays a warning on the display 102 and displays the user. To that effect and to avoid shifting to the staple binding mode. At this time, the system control unit 420 disables various setting inputs to the management apparatus 20 by the user for executing the staple binding process. As a result, the user can be prompted to select the correct mode, and the user's setting man-hours can be reduced.

  Note that the device mounting portion 452 is provided with a device detection sensor 464 that detects which of the collating device 410 and the gluing device 500 is mounted, or neither of which is mounted. The device detection sensor 464 includes a switch that is turned on by a protrusion provided on the gluing device 500 only when the gluing device 500 is mounted. Note that other types of switches may be employed for the device detection sensor 464.

  For example, when the attachment of the needle binding mechanism 470 to the mechanism housing unit 454 is detected, but no attachment of any device to the device attachment unit 452 is detected, the system control unit 420 warns the display 102. Display this and inform the user accordingly. Further, for example, when the attachment of the collating device 410 to the device attachment portion 452 is detected even though the attachment of the crimping mechanism 510 to the mechanism accommodating portion 454 is detected, any of the attachment to the device attachment portion 452 is detected. In the case where the installation of the device is not detected, the system control unit 420 displays a warning on the display 102 and notifies the user to that effect.

  In these cases, the system control unit 420 avoids the transition to both the glue binding mode and the needle binding mode when any selection request of the glue binding mode and the needle binding mode is acquired. In addition, when the start request for the bookbinding process in which the start button is clicked by the user is acquired, the system control unit 420 avoids the bookbinding process. Thereby, malfunction of the bookbinding system 400 can be avoided.

(Third embodiment)
FIG. 13 is an overall configuration diagram of a bookbinding system 600 according to the third embodiment. Hereinafter, the same parts as those in the bookbinding system according to the above-described embodiment are denoted by the same reference numerals and description thereof is omitted.

  The bookbinding system 600 includes a collating device 410, a gluing device 500, a saddle stitch folding device 602, a cutting device 16, and a management device 20. The saddle stitch folding device 602 includes a binding device 604, a folding device 480, and a folding reinforcement device 482. In the third embodiment, the binding device 604 includes both a crimping mechanism 510 that performs a crimping process and a needle binding mechanism 470 that performs a needlebinding process. The crimping mechanism 610 includes a pusher 612 and a cradle 614. The binding control unit 620 is provided to control the operation of the binding device 604.

  The crimping mechanism 610 has a lifting mechanism (not shown) provided with a cam mechanism and a motor. By operating this motor, the pusher 612 moves up and down via the cam mechanism.

  The crimping mechanism 610 operates the lifting mechanism to push the uppermost sheet downward by the pusher 612 when the last sheet among the sheets included in one booklet is stacked. As a result, the sheets stacked on the transport belt are sandwiched and pressed by the pusher 612 and the receiving table 614.

  FIG. 14 is a perspective view of the needle binding mechanism 470 and the pressure bonding mechanism 610. The needle binding mechanism 470 is provided with two drivers 472 for driving the binding needle into the paper in the paper width direction. Three pushers 612 are provided, two are arranged on both sides of the two drivers 472, and one is arranged between the drivers 472.

  The pusher 612 is formed in an elongated rectangular plate shape. The pusher 612 is disposed above the belt conveyance mechanism 456 so as to extend in the vertical direction. A pressing surface 612a for pressing the paper is formed on the lower surface of the pusher 612. In order to press the paper on which the glue has been transferred, a concave portion extending in the paper width direction may be formed at the center of the pressing surface 612a, and the pressing surface 612a of the pusher 612 may be coated with fluorine resin or fluorine. The point that the paste is difficult to transfer, such as resin-containing nickel plating, may be the same as described above.

  FIG. 15 is a diagram illustrating a relative positional relationship between the glue transfer mechanism 30, the needle binding mechanism 470, and the pressure bonding mechanism 610. The three pushers 612 are arranged so as to fit in the width direction of the paper 2. The cradle 614 is disposed below the pusher 612. Two conveyor belts of the belt conveyance mechanism 456 are provided, and each is arranged between the pusher 612 and the driver 472 so as to extend in the sheet conveyance direction.

  In the third embodiment, the glue transfer mechanism 30 is provided with three glue sheet units 120. Each of the glue sheet units 120 is disposed on the upstream side of each of the three pushers 612. As a result, the glued portion by the glue sheet unit 120 can be appropriately crimped by the pusher 612.

  Returning to FIG. The management device 20 is provided so that the user can select the needle binding mode and the glue binding mode. The system control unit 420 acquires the mode selection request input by the user in this way. When the start button is clicked by the user in the state where the glue binding mode is selected, the system control unit 420 acquires the input as a glue binding bookbinding request. The glue binding bookbinding request is used by the binding control unit 620 as a request for executing the crimping process. When the start button is clicked by the user while the staple binding mode is selected, the system control unit 420 acquires the input as a staple binding request. The staple binding bookbinding request is used by the binding control unit 620 as an execution request for staple binding processing. Therefore, the system control unit 420 functions as an execution request acquisition unit that acquires these execution requests.

  In the third embodiment, the folding device 480 performs a crimping and folding process in which a plurality of sheets, to which at least one of adjacent sheets is glued, is crimped while being sandwiched by a pair of folding rollers 78. Provided possible. The system control unit 420 is provided so as to be able to acquire a glue binding bookbinding request by this crimping and folding process.

  Specifically, the management device 20 executes the crimping and folding process in the folding device 480 and performs the bookbinding separately from the “first glue binding mode” for performing the crimping process and binding in the binding device 604. The user can select a “second glue binding mode” for this purpose. When the user clicks the start button in the state where the second glue binding mode is selected, the system control unit 420 acquires the input as a glue binding bookbinding request for executing the crimping and folding process. The glue binding bookbinding request is used in the folding device 480 as an execution request for the crimping and folding process. Hereinafter, the bookbinding request for executing the crimping process in the binding device 604 is referred to as a “first glue binding bookbinding request”, and the bookbinding request for executing the crimping and folding process in the folding device 480 is referred to as a “second glue binding bookbinding request”.

  In the management apparatus 20, a special mode in which only the cover is glued and the remaining body is stapled may be provided so as to be selectable by the user. When the user clicks the start button of the management apparatus 20 with the special mode selected, the system control unit 420 acquires the input as an execution request for the special bookbinding process.

  When the execution request for the special bookbinding process is acquired, the collating apparatus 410 superimposes only the sheets to be included in the body and carries them out to the gluing apparatus 500, and then carries out the cover sheet alone to the gluing apparatus 500. The gluing device 500 avoids gluing of the real paper and carries it out to the binding device 604. The gluing device 500 performs a gluing process on the cover and reverses it by the paper reversing mechanism 502, and then carries it out to the binding device 604.

  First, the staple binding mechanism 470 executes a staple binding process on a real sheet. The pressure-bonding mechanism 610 performs a pressure-bonding process when a glued cover is stacked on the stapled paper. Thereafter, the folding process and the cutting process are executed in the same manner as other bookbinding processes. In this way, by applying a gluing process only to the cover and press-bonding it to the main body, it is possible to create a good-looking booklet in which the binding needle is not visually recognized from the outside.

  FIG. 16 is a flowchart showing the operation of the bookbinding system 600 according to the third embodiment. The processing in this flowchart starts when the bookbinding system 600 is powered on, and is then repeatedly executed every predetermined time.

  The system control unit 420 determines whether a staple binding bookbinding request has been acquired (S10). When the needle binding bookbinding request is acquired (Y in S10), the system control unit 420 executes the needle binding bookbinding process (S12).

  When the staple binding bookbinding request has not been acquired (N in S10), the system control unit 420 determines whether or not the first glue binding bookbinding request has been acquired (S14). When the first glue binding bookbinding request is acquired (Y in S14), the system control unit 420 executes the first glue binding bookbinding process (S16).

  When the first glue binding bookbinding request has not been acquired (N in S14), the system control unit 420 determines whether or not the second glue binding bookbinding request has been acquired (S18). When the second glue binding bookbinding request is acquired (Y in S18), the system control unit 420 executes the second glue binding bookbinding process (S20). If the second glue binding bookbinding request has not been acquired (N in S18), the processing in this flowchart is temporarily terminated.

  FIG. 17 is a flowchart showing the procedure of the staple binding process in S12 in FIG. When the staple binding bookbinding request is acquired, the collation device 410 first superimposes one sheet of paper and carries it out to the gluing device 500 (S40). The gluing device 500 carries out the plurality of loaded papers to the binding device 604 without gluing (S42). The binding device 604 arranges a plurality of loaded papers on the transport belt of the belt transport mechanism 456 with the ends aligned so that the binding needle is driven in the center of the paper transport direction. The crimping mechanism 610 executes a staple binding process on the plurality of sheets (S44).

  The folding device 480 executes a folding process for folding the plurality of sheets fed in at a portion bound by the binding needle (S46). The cutting device 16 executes a cutting process for cutting the three sides of the booklet carried in from the saddle stitch folding device 414 (S48).

  FIG. 18 is a flowchart showing the procedure of the first glue binding process in S16 in FIG. When the first glue binding book acquisition request is acquired, the collation apparatus 410 first carries out the sheets to be included in the booklet to be created one by one to the gluing apparatus 500 (S60). The gluing device 500 executes a gluing process on the loaded paper so that at least one of the adjacent papers is glued when a plurality of papers included in the booklet to be created are overlapped (S62).

  Specifically, the gluing device 500 avoids transfer of glue only to the paper that is finally transported to the binding device 604 among the plurality of papers included in the booklet to be created, and raises the pusher 280 for other papers. Then, the sheet is pressed against the glue sheet 212 of the glue sheet unit 120, and the glue is transferred to the upper surface thereof. At this time, the gluing device 500 adjusts the gluing position on the paper so as to transfer the gluing to the center in the paper transport direction by controlling the stop position of the paper.

  The binding device 604 stacks the paper carried from the gluing device 500 while aligning the ends so that the center of the paper in the conveyance direction can be crimped. At this time, the pressure-bonding mechanism 610 operates the bag jogger 460 so as to press the rear end of the paper stacked on the upper surface of the conveyance belt of the belt conveyance mechanism 456 toward the downstream side every time the paper is carried in. As a result, the leading edge of the paper is pressed against the stopper 458 to align the edges of the paper. The pressure-bonding mechanism 610 performs a pressure-bonding process on the sheets stacked in this way (S64).

  The folding device 480 performs a folding process for folding the plurality of loaded sheets at the center in the transport direction (S66). The cutting device 16 performs a cutting process for cutting the three sides of the booklet carried from the saddle stitch folding device 414 (S68).

  FIG. 19 is a flowchart showing the procedure of the second glue binding bookbinding process of S20 in FIG. When the second glue binding bookbinding request is acquired, first, the collating apparatus 410 carries out the sheets to be included in the booklet to be created one by one to the gluing apparatus 500 (S80). The gluing device 500 performs a gluing process on the loaded paper so that at least one of the adjacent papers is glued when a plurality of papers included in the booklet to be created are overlapped (S82). The gluing method at this time is the same as S62 in FIG.

  The binding device 604 carries out the sheets carried in from the gluing device 500 one by one to the folding device 480 without stacking or pressure bonding (S84). The folding device 480 adjusts the position of the folding stopper 74 in the conveyance direction, and stacks the paper loaded from the binding device 604 while aligning the ends so that the center in the conveyance direction can be folded. The folding device 480 performs a crimping and folding process for crimping the sheets stacked in this manner while folding (S86). The cutting device 16 performs a cutting process for cutting the three sides of the booklet carried from the saddle stitch folding device 414 (S88).

  Note that the management device 20 is provided so that the user can input the number of sheets of paper that make up the booklet to be created. The system control unit 420 acquires the number of sheets input by the user in this way. Therefore, the system control unit 420 also functions as a number acquisition unit that acquires the number of sheets of a plurality of sheets constituting the booklet to be created.

  The system control unit 420 avoids performing the crimping and folding process by the folding device 480 when the obtained number of sheets is equal to or greater than the predetermined number. Specifically, a setting input screen in the management apparatus 20 is provided so that the second glue binding mode cannot be selected when the number of acquired sheets is equal to or greater than a predetermined number. When the second glue binding mode is selected, when the user inputs a number of sheets equal to or larger than a predetermined number of sheets constituting the booklet to be created, the system control unit 420 displays the number on the display 102. A warning is displayed and further acquisition of the number of input sheets is avoided. As the number of sheets increases, it may become more difficult to crimp the sheets in the crimping and folding process. Thus, by avoiding the crimping and folding process when the number of sheets is equal to or greater than the predetermined number, it is possible to avoid a situation where the sheets are not properly crimped.

(Fourth embodiment)
FIG. 20 is an overall configuration diagram of a bookbinding system 700 according to the fourth embodiment. Hereinafter, the same parts as those in the bookbinding system according to the above-described embodiment are denoted by the same reference numerals and description thereof is omitted.

  The bookbinding system 700 includes a collating device 410, a gluing device 500, a saddle stitch folding device 702, a cutting device 16, and a management device 20. The saddle stitch folding device 702 includes a binding device 704, a folding device 480, and a folding reinforcement device 482. In the fourth embodiment, the binding device 704 is provided with a multi-function binding mechanism 710. The multi-function binding mechanism 710 is provided so that both the crimping process and the needle binding process can be executed. The binding control unit 720 is provided to control the operation of the binding device 704.

  FIG. 21 is a diagram illustrating a configuration of the multi-function binding mechanism 710. The multi-function binding mechanism 710 includes a driver 712, a clincher 714, and a receiving member 716. The driver 712 drives the binding needle into the paper while moving toward the paper. The clincher 714 bends the binding needle at the point where the binding needle penetrates the paper.

  A pressing surface 712 a for pressing the paper is provided on the lower surface of the driver 712. The receiving member 716 has a driver 712 and a receiving surface 716a for gripping paper. The receiving member 716 is fixed so that the receiving surface 716 a is positioned on the upper surface of the conveying belt of the belt conveying mechanism 456.

  When the staple binding bookbinding request is acquired, the multi-function binding mechanism 710 drives the binding needles onto a plurality of sheets by the driver 712 and the clincher 714 and binds them. When the first glue binding book acquisition request is acquired, the multi-function binding mechanism 710 presses and binds a plurality of sheets by being sandwiched between the pressing surface 712a of the driver 712 and the receiving surface 716a of the receiving member 716. The operation of the bookbinding system 700 when acquiring the staple binding bookbinding request, when acquiring the first glue binding bookbinding request, and when acquiring the second glue binding bookbinding request is the same as the flowcharts of FIGS. .

  Further, a buffer member that can advance between the pressing surface 712a of the driver 712 and the paper may be provided. In this case, the buffer member is formed of an elastic member such as rubber. The buffer member is driven by an actuator such as a solenoid. When the first glue binding bookbinding request is acquired, the multi-function binding mechanism 710 performs the crimping process by lowering the driver 712 with the buffer member advanced between the pressing surface 712a of the driver 712 and the paper. To do. By interposing the buffer member in this way, it is possible to suppress the influence on the paper such as the trace of the pressing surface 712a of the driver 712 remaining on the paper.

  22A to 22C are diagrams illustrating the operation of the multi-function binding mechanism 710. FIG. 22A to 22C are views when one of the two multi-function binding mechanisms 710 is viewed from the viewpoint Q of FIG.

  FIG. 22A is a diagram illustrating a state of the multi-function binding mechanism 710 when the needle binding process is executed. The multi-function binding mechanism 710 further includes a needle feed mechanism 730 and a switching mechanism 732. The needle feed mechanism 730 includes rollers 736 and 738 that are in contact with each other. The roller 736 is driven by a motor (not shown), and the roller 738 follows the roller 736. The binding needle 734 is sandwiched between the rollers 736 and 738 and is fed to the tip of the driver 712 by driving the roller 736.

  The switching mechanism 732 allows the binding needle to be fed to the tip of the driver 712 so as to drive the binding needle into the paper when executing the staple binding process, and disables the binding needle from being driven into the paper when performing the crimping process. Therefore, feeding of the binding needle to the tip of the driver 712 is avoided. Specifically, the switching mechanism 732 includes a swing rod 740, a cam follower 744, a cam 746, a support member 748, and a coil spring 750. One end of the swing rod 740 supports the rotation shaft of the roller 736 so as to be rotatable, and the other end is supported by the housing of the multi-function binding mechanism 710 so as to swing about the swing shaft 742. At the center of the swing rod 740, a disc-shaped cam follower 744 is rotatably supported. The cam 746 is disposed so as to contact the cam follower 744. The cam 746 is provided so as to be driven by a motor (not shown).

  The coil spring 750 biases one end of the swing rod 740 away from the support member 748 fixed to the housing of the multi-function binding mechanism 710. As a result, the roller 736 is pressed against the roller 738 and the binding needle 734 can be fed. When executing the staple binding process, the binding control unit 720 rotates the rollers 736 and 738 to feed the binding needle 734 to the tip of the driver 712, and then lowers the driver 712 to cut the binding needle 734 and to the sheet. The multi-function binding mechanism 710 is operated to drive the cut binding needle 734.

  FIG. 22B is a diagram illustrating an initial state of the multi-function binding mechanism 710 when performing the crimping process. When performing the crimping process, the binding control unit 720 retracts the binding needle 734 from below the driver 712 by rotating the roller 736 in the reverse direction.

  FIG. 22C is a diagram illustrating a state of the next multi-function binding mechanism 710 of FIG. The binding control unit 720 swings the swing rod 740 by rotating the cam 746 and releases the binding of the binding needle 734 between the roller 736 and the roller 738. As a result, the feeding of the binding needle 734 accompanying the lowering operation of the driver 712 can be avoided. When the cam 746 is rotated, the binding controller 720 lowers the driver 712 to crimp the paper.

  When the multi-function binding mechanism 710 is in the state shown in FIG. 22 (c), the next time the needle binding process is executed, the reverse process is executed. In other words, the binding control unit 720 first rotates the cam 746 to swing the swing rod 740 to the original position, so that the binding needle 734 is held between the roller 736 and the roller 738. Next, the roller 736 is rotated to feed the binding needle 734 below the driver 712, and finally the driver 712 is lowered to drive the binding needle 734 onto the paper.

  FIG. 23 is a diagram illustrating a relative positional relationship between the glue transfer mechanism 30 and the multi-function binding mechanism 710. Two drivers 712 are juxtaposed in the paper width direction. Two belts of the belt conveyance mechanism 456 are provided, and each is arranged to extend in the paper conveyance direction outside the driver 712. In the fourth embodiment, the glue transfer mechanism 30 is provided with two glue sheet units 120. Each of the glue sheet units 120 is disposed on the upstream side of each of the two drivers 712. Thereby, the pasting location by the glue sheet unit 120 can be appropriately crimped by the driver 712.

(Fifth embodiment)
FIG. 24 is an overall configuration diagram of a bookbinding system 800 according to the fifth embodiment. The bookbinding system 800 is configured in the same manner as the bookbinding system 600 according to the third embodiment except that a sheet feeding device 802 is provided instead of the collating device 410.

  The sheet feeding device 802 is configured in the same manner as the sheet feeding device 12 according to the first embodiment except that an image sensor 804 is provided corresponding to each of the A tray 22A and the B tray 22B. The image sensor 804 includes a CCD (Charge Coupled Device) image sensor. A CMOS (Complementary Metal Oxide Semiconductor) image sensor may be used. Each of the image sensors 804 captures an image recorded in a predetermined area of the paper stacked on each of the A tray 22A and the B tray 22B. The paper feed device 802 is provided with a paper feed control unit 806 that executes control of an internal actuator and the like. The paper feed control unit 806 transmits image data captured by each of the image sensors 804 to the system control unit 420.

  For example, when all the sheets to be included in the booklet to be created are sent out from the A tray 22A, a plurality of sheets of sheets are stacked on the A tray 22A in the reverse order from when the sheets are stacked. At this time, among the sheets included in one booklet, the A tray 22A has an image indicating that on the upper surface of the sheet sent last. In this case, an image indicating that the sheet is to be sent out last is attached to the cover sheet.

  The system control unit 420 uses the image data captured by the image sensor 804 to determine whether it is the last sheet for one book. If it is determined that the last sheet is a glue binding process, the gluing device 500 avoids gluing to the sheet, and the crimping mechanism 610 executes the crimping process when the sheet is stacked. To control. If it is a staple binding process, the staple binding mechanism 470 executes the staple binding process when the sheets are stacked. Other operations are the same as those in the third embodiment.

  For example, when only the cover sheet is sent out from the B tray 22B and other sheets are sent out from the A tray 22A, the A tray 22A has an upper surface for the last sheet to be included in one booklet. An image indicating that is attached. In this case, an image indicating that the sheet is finally sent out is attached to the sheet arranged under the cover. In the binding device 604, after the cover sheet fed from the B tray 22B is stacked, the sheet is pressed. Processing or needle binding processing is executed.

  As described above, even when the paper feeding device 802 is used, the staple binding process and the glue binding process can be alternatively executed. In the bookbinding system according to the second embodiment or the fourth embodiment, a paper feeding device 802 may be used instead of the collating device 410. Further, instead of the paper feeding device 802 and the collating device 410, an image forming apparatus that forms a print image on a sheet such as an ink jet recording apparatus may be provided.

  The present invention is not limited to the above-described embodiments, and an appropriate combination of the elements of each embodiment is also effective as an embodiment of the present invention. 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 the above embodiment, an example in which the operator manually rotates the feed amount adjustment cam 230 for adjusting the feed amount of the glue sheet 212 has been described. In the modification, the feed amount adjusting cam 230 may be rotated by driving means such as a stepping motor, and the rotation command signal may be output from the management PC 100. By adjusting the rotation amount of the stepping motor, it is possible to adjust the rotation position of the feed amount adjusting cam 230, the rotation position of the lever 228, and eventually the glue feed amount. Further, since the feed amount can be calculated from the rotation amount of the stepping motor, the transfer length l can be calculated from the feed amount, and the center position of the glue transfer portion can be calculated. The management PC 100 determines the stop position of the stopper 290 so that the center position of the glue transfer portion is located at the center in the sheet transport direction of the paper P from the calculated center position of the glue transfer portion and the size information of the paper P. Can be determined.

  In the above embodiment, as shown in FIG. 3, the configuration example in which the detection lever 262 of the near-end detection member 210 is supported by the frame 200 of the glue sheet unit 120 is shown. In the modification, the detection lever 262 is supported outside the glue sheet unit 120, that is, by the main body casing of the gluing device, and the roller 268 at the tip thereof is brought into contact with the glue sheet 212 wound around the supply reel 202. It is good. If the detection lever 262 can be inserted by providing a slit below the frame 200 and the detection lever 262 is installed below the glue sheet unit 120 so that the roller 268 contacts from below, the main body of the glue sheet unit 120 There is no hindrance to the attachment to the casing.

  In the above embodiment, the configuration example of the glue sheet 212 is shown in FIGS. 6A and 6B. However, the paste segments 302 having various shapes and sizes may be arranged in addition to the illustrated embodiment. Of course it is good. Moreover, in the said embodiment, the arrangement | positioning direction which connects the glue segments which adjoin most is inclined with respect to the longitudinal direction of the base material sheet 300, and the example which can take the uniformity of transfer of glue was shown. In the modification, the glue sheet 212 itself may be installed so as to be inclined with respect to the pressure receiving surface 240. For example, the supply reel 202 and the take-up reel 204 may be assembled to the frame 200 such that the respective rotation shafts are inclined with respect to the paper transport direction. Alternatively, the glue sheet unit 120 itself may be attached to the main casing of the gluing device in a manner that it is inclined with respect to the paper transport direction.

  In the above-described embodiment, one specific configuration example of the bookbinding system is shown, but it goes without saying that various configurations other than that can be adopted. In the above-described embodiment, an example of an apparatus that binds a saddle-stitched booklet has been shown. However, the above-described configuration of the gluing apparatus can be effectively applied even to a bookbinding system that binds the edge of a sheet. The gluing device of the present invention is not limited to a bookbinding system, and can be applied to any device provided with a gluing mechanism that transfers a glue by pressing a part of a glue sheet against a sheet.
