This is a device that punches a recording sheet (hereinafter simply referred to as a sheet), then performs a binding process with a predetermined binding component, and discharges the recording sheet. The binding apparatus 100 is preferably used side by side with a copying machine, a printing apparatus (image forming apparatus), and the like, and has a height similar to that of a copying machine, a printing machine, or the like.

  A binding apparatus 100 illustrated in FIG. 1A includes an apparatus main body (housing) 101. A right door 70 and a left door 71 are provided on the front side of the apparatus main body 101. The right door 70 and the left door 71 are attached to the apparatus main body 101 so as to be openable and closable by hinges (not shown). The binding device 100 includes a stacker 63 below the left door 71. The stacker 63 is provided with a stacker tray 73. The stacker tray 73 receives a booklet in which a binding component is bound to a sheet bundle and is discharged, and adjusts the height according to the thickness and the number of booklets of the booklet and accumulates the booklet. Further, the stacker 63 is provided with a stacker window 72 for confirming the number of accumulated booklets on the front side of the apparatus main body 101.

  1B is a state in which the right door 70 and the left door 71 of the binding device 100 illustrated in FIG. 1A are opened. In the apparatus main body 101, a paper transport unit 10 is provided. The paper transport unit 10 includes a first transport path 11 and a second transport path 12. The conveyance path 11 conveys the paper 3 output from a copier or the like toward the conveyance path 12.

  The transport path 12 has a switchback function that can switch the transport path from the transport path 11. Here, the switchback function decelerates and stops the conveyance of the sheet at a predetermined position on the conveyance path 11, and then switches the conveyance path of the sheet from the conveyance path 11 to the conveyance path 12, and moves the sheet in the reverse direction. The function to send out.

  A punch processing unit 20 is disposed on the downstream side of the conveyance path 12. The punch processing unit 20 switches back from the conveyance path 11 and punches two or more binding holes at one end of the sheet conveyed by the conveyance path 12. A punch residue storage unit 26 is provided below the punch processing body so as to store punch scraps cut off by the punch processing unit 20.

  A binder paper alignment unit 30 is disposed downstream of the punch processing unit 20 so that the positions of the holes of a plurality of sheets discharged from the punch processing unit 20 are aligned and temporarily held (accumulated).

  The binder paper alignment unit 30 guides the paper to a predetermined position when the paper enters and prepares the rear end of the paper. Further, the binder paper aligning unit 30 guides the leading edge and the lateral edge of the sheet to an appropriate position by a multi-shaped rotating member for aligning the leading edge and the lateral edge of the sheet to the reference position.

  A bind processing unit 40 is disposed on the downstream side of the binder paper alignment unit 30. The bind processing unit 40 creates a booklet by binding a plurality of sheet bundles aligned by the unit 30 with binding components. The binding processing unit 40 includes a binding mechanism 41 and a binder (binding component) cassette 42. The binder cassette 42 is set with a plurality of binding parts 43 (see FIG. 9) of a predetermined size that are unfolded before processing and have an annular shape after processing. For example, the binding component 43 is injection-molded, and a plurality of types of diameters are prepared according to the thickness of the sheet bundle. The binding mechanism 41 constitutes an example of a binding unit, receives a binding component of a predetermined size from the binder cassette 42 in which the unfolded binding component 43 is accommodated, and binds the binding component into a hole punched at a predetermined position on the sheet. 43 is bound.

  In this example, the binding mechanism 41 moves so as to reciprocate between the paper conveyance direction of the binder paper alignment unit 30 and the binding component provision direction of the binder cassette 42. First, the binding mechanism 41 pulls out and holds one binding component 43 from the binder cassette 42 at a position orthogonal to the transport direction of the transport path 11, and in this state, a position where the paper transport direction of the binder paper alignment unit 30 can be seen. Rotate to. Next, at this position, the binding mechanism 41 receives the sheet bundle in which the punch holes are positioned from the binder paper aligning unit 30, and inserts the binding component 43 into the punch holes and fits them. After the fitting, the binding mechanism 41 releases the binding component 43. When the binding component 43 is bound to the sheet bundle and a booklet is created, the binder paper alignment unit 30 delivers the created booklet to the discharge unit 60.

  A discharge unit 60 is disposed on the downstream side of the bind processing unit 40. The discharge unit 60 receives the booklet created by the bind processing unit 40 and discharges it. The discharge unit 60 includes, for example, a first belt unit 61, a second belt unit 62, and a stacker 63.

  The belt unit 61 receives the booklet falling from the binder paper alignment unit 30 and switches the booklet sending direction. For example, after receiving the booklet, the belt unit 61 turns from a position where the binder paper alignment unit 30 can see the paper conveyance direction to a position where the stacker 63 can be seen.

  A belt unit 62 is disposed at a position where the stacker 63 can be seen. The belt unit 62 receives the booklet whose sending direction is switched by the belt unit 61 and relays the booklet, and delivers the booklet to the stacker 63. The stacker 63 accumulates booklets conveyed by the belt units 61 and 62. In this way, a booklet 90 shown in FIG. 2D is created.

  Next, a paper processing method according to the present invention will be described. 2A to 2D are process diagrams illustrating an example of functions of the binding device 100. FIG. The sheet 3 shown in FIG. 2A is fed from the upstream side (such as a copying machine) of the binding device 100 and has no punch holes. The sheet 3 is transported toward a predetermined position on the transport path 11 illustrated in FIG. 1, and is decelerated and stopped at a predetermined position on the transport path 11. Thereafter, the conveyance path of the sheet 3 is switched from the conveyance path 11 to the conveyance path 12 by the switchback function, and the sheet 3 is sent in the reverse direction and conveyed to the punch processing unit 20.

  In the punch processing unit 20, a predetermined number of binding holes are formed at one end of the sheet 3 as shown in FIG. The sheet 3 ′ with the binding holes punched is conveyed to the bind sheet aligning unit 30. When the number of sheets set in advance is reached, the bind sheet aligning unit 30 aligns the binding holes as in the sheet 3 ″ shown in FIG. 2C, for example, and cooperates with the bind processing unit 40. Then, the binding component 43 is inserted and fitted into the hole, whereby the booklet 90 shown in Fig. 2 (D) in which the binding component 43 is fitted can be obtained. It is discharged and accumulated in the stacker 63.

  FIG. 3 is a schematic diagram illustrating an arrangement example (part 1) of the binder paper alignment unit 30, the binding mechanism 41, and the binder cassette 42. The binding device 100 includes a binding mechanism 41 disposed downstream of the binder paper alignment unit 30 and the binder cassette 42 illustrated in FIG. 3, and the binder paper alignment unit 30 and the binder radially upstream from the binding mechanism 41. It has a substantially V-shaped arrangement structure in which the cassette 42 is arranged.

  The binding mechanism 41 has a binding mechanism rotation shaft 41d. The binding mechanism rotation shaft 41d is disposed in the vicinity of a region where the direction I for discharging the sheet bundle 3 ″ downstream from the binder paper alignment unit 30 and the direction II for discharging the binding component 43 downstream from the binder cassette 42 intersect. Is done.

  The binder paper alignment unit 30 and the binder cassette 42 are arranged on the left side and the right side in an arc shape (radially) on the upstream side with respect to the binding mechanism rotation shaft 41d. The binding mechanism 41 operates to reciprocate between the binder paper alignment unit 30 and the binder cassette 42. The binding mechanism 41 has an opening 41c at the top of the main body. The binding component take-out position (direction II) is a position where the opening 41c of the binding mechanism 41 takes a posture facing the binder cassette 42 side.

  An arrow Y <b> 1 shown in FIG. 3 is the rotation direction of the binding mechanism 41. In this example, when the above-described binding component take-out position (direction II) is set as the home position with reference to the binding mechanism rotation shaft 41d, the sheet is rotated counterclockwise from the home position to the paper binding position (direction I). On the other hand, it rotates from the paper binding position to the home position in the clockwise direction.

  For example, in the binding processing unit 40, the binding mechanism 41 moves to the downstream side of the binder cassette 42, receives a binding component 43 (see FIG. 9) of a predetermined size, and holds the binding component 43 received from the binder cassette 42. Rotating counterclockwise with reference to the binding mechanism rotating shaft 41d, moving to the downstream side of the binder paper alignment unit 30, and binding the sheet bundle 3 "shown in FIG. In this way, the booklet 90 shown in Fig. 2 (D) can be created by moving the binding component 43 received from the binder cassette 42 to the downstream side of the binder paper alignment unit 30 for binding processing.

  In this example, the binding mechanism 41 receives the binding component 43 from the binder cassette 42 when the binder paper alignment unit 30 aligns the paper 3 '. In this way, since the paper alignment process and the binding part 43 receiving process can be performed in parallel, the binding process can be speeded up and the throughput of the binding device 100 can be improved.

  FIG. 4 is a schematic diagram illustrating an arrangement example (part 2) of the binder paper alignment unit 30, the binding mechanism 41, and the binder cassette 42. The binding mechanism 41 shown in FIG. 4 has the binding mechanism 41 in the binding part take-out position (direction II) shown in FIG. 3 for the process of binding the binding part 43 onto the paper aligned by the binder paper alignment unit 30. In this state, the binding mechanism rotating shaft 41d is used as a reference, and it is rotated counterclockwise as indicated by the arrow Y1 and moved to the paper binding position (direction I). Here, the paper binding position is a position in which the opening 41c of the binding mechanism 41 takes a posture in which the binder paper alignment unit 30 faces the paper conveyance direction. According to the binding processing unit 40 shown in FIG. 4, the binding mechanism 41 creates a booklet 90 by binding the binding component 43 to the paper 3 ″ provided from the binder paper alignment unit 30 at the paper binding position (direction I). After that, the binding parts take out position (direction II).

  FIG. 5A is a perspective view illustrating a configuration example of the binding mechanism 41. FIG. 5B is a perspective view illustrating a configuration example of the upper end portion of the binding component gripping portion 41b. A binding mechanism 41 shown in FIG. 5A includes a main body portion 41a and a binding component gripping portion 41b inside the main body portion 41a. The binding component gripping portion 41b constitutes an example of a holding portion, and is configured to be movable up and down so that the front end portion is positioned inside and outside the main body 41a through the upper opening 41c of the main body 41a. The binding part 43 is held.

  5B, according to the enlarged configuration example of the upper end portion of the binding component gripping portion 41b, the upper end portion of the binding component gripping portion 41b includes a plurality of binding component gripping claws 41h, A gripping claw holder 41v and a holder fixing frame 41w are provided. In this example, the gripping claw holder 41v is fixed to the holder fixing frame 41w. The binding component gripping claws 41h are positioned inside the gripping claw holder 41v so that the upper end portion protrudes above the gripping claw holder 41v. In this way, the binding component gripping portion 41b that binds the binding component 43 is configured.

  FIG. 6A is a cross-sectional view illustrating an internal configuration example (No. 1) of the binding mechanism 41. A binding mechanism 41 illustrated in FIG. 6A illustrates a configuration example of related members on the cutting plane of the binding mechanism 41 illustrated in FIG.

  In this example, the binding mechanism 41 has a binding claw opening / closing function for binding the binding component 43. In order to operate this function, the binding mechanism 41 includes a fitting portion 41x. The fitting portion 41x includes a binding claw 41z, a binding claw link A41l, a binding claw link B41m, a binding portion link C41n, a spring 41o, a binding claw cam 41p, and a binding mechanism driving motor 45a (see FIG. 10). The fitting portion 41x inserts both ends of the binding component 43 held by the binding component gripping portion 41b into the hole of the paper and fits them.

  The binding claws 41z are provided on both sides of the opening 41c along the longitudinal direction of the opening 41c. Further, the binding claw 41z has a closing portion 41q, and the closing portion 41q contacts the binding component 43 when binding the binding component 43. Each binding claw 41z is rotatably connected to the upper end of a binding claw link A41l having an L-shape. Each binding claw link A41l is rotatably attached to the main body 41a at a binding claw link A rotation axis A41r located at a substantially central portion of each binding claw link A411.

  Further, the two binding claw links A41l are rotatably connected at a link coupling portion A46j located at the end opposite to the end to which the binding claw 41z is connected. Further, the upper end portion of the binding claw link B41m having a predetermined length in the vertical direction is rotatably connected to the two binding claw links A41l at the link coupling portion A46j.

  The binding claw link B41m constitutes an example of a link member, and has a long hole-shaped binding claw link B coupling hole 41s at the lower end. The binding claw link B coupling hole 41s constitutes an example of a switching hole for switching the binding stroke. The binding claw link B coupling hole 41s is fitted with a projection-shaped link coupling portion B46k of the binding portion link C41n, and the binding claw link B41m and the binding claw link C41n are rotatably connected. Further, the binding claw link B41m is attached to the main body 41a via a spring 41o at the center. An upward force is applied to the binding claw link B41m by the spring 41o.

  The binding claw link C41n is rotatably attached to the main body 41a on the binding claw link C rotating shaft 41t. Further, when the binding claw cam 41p rotates as indicated by an arrow F, the binding claw link C41n rotates around the binding claw link C rotation shaft 41t.

  With the above configuration, the opening and closing operation of the binding claw 41z is performed. In this example, the binding claw cam 41p rotates in the clockwise direction of FIG. 6 indicated by the arrow F, the binding claw link C rotates counterclockwise, and a downward force is applied to the binding claw link B41m. As a result, a counterclockwise force is applied to the binding claw link A41l shown on the right side of FIG. 6, a clockwise force is applied to the binding claw link A411 shown on the left side, and each binding claw 41z is indicated by an arrow E. The binding claw 41z is closed by moving in the direction. The binding claw 41z shown in FIG. 6A is in a substantially closed state.

  Further, the binding mechanism 41 has a function of adjusting a range in which the binding claw 41z is bound in accordance with the diameter size of the binding component 43. In order to operate this adjustment function, the binding mechanism 41 includes a stroke switching unit 41y. The stroke switching unit 41y includes a binding component adjustment cam 41u, a binding component adjustment unit 46l, and a binding component adjustment motor 45b (see FIG. 10), and switches the binding stroke in the fitting unit 41x. Here, the binding stroke refers to a process from the binding start position P to the binding completion position Q shown in FIG. In this example, the binding start position P is a position where the binding claw link B41m starts to move downward by the rotation of the binding claw cam 41p, and the binding completion position Q is the binding claw link after the cam 41p is rotated. This is the position when B41m moves to the bottom.

  The binding component adjustment cam 41u constitutes an example of a switching cam and is connected to the binding component adjustment portion 46l. The binding component adjusting portion 46l is attached so as to be movable left and right, and is coupled to the binding claw link B41m. Further, the binding component adjusting portion 46l is moved left and right by the cam 41u to switch the binding claw link B coupling hole 41s of the binding claw link B41m. For example, the binding claw link B41m coupled to the binding component adjusting unit 46l is rotated left and right around the link coupling unit A46j. The position of the binding claw link B coupling hole 41s of the binding claw link B41m is changed by the rotation of the binding claw link B41m. By changing the position of the coupling hole 41s, the coupling position of the projecting link coupling portion B46k is switched, and the binding stroke for binding the binding claw 41z described above is adjusted.

  Here, the binding mechanism 41 is locked in the binding claw link B coupling hole 41s in addition to the adjustment hole for adjusting the binding stroke for binding the binding claw 41z in accordance with the size of the diameter of the binding component 43. An avoidance hole R4 shown in FIG. 6B is provided. For example, when the operation of binding the leading end of the binding component 43 to a place other than the punch hole of the paper 3 and binding the binding claw 41z is interrupted by mistake, the protruding link coupling portion B46k is positioned in the avoidance hole R4. .

  FIG. 6B is an explanatory diagram illustrating a configuration example of the binding claw link B41m. The binding claw link B coupling hole 41s of the binding claw link B41m shown in FIG. 6B has adjustment holes R1 to R3 and an avoidance hole R4. Regarding the distance between each of the adjustment holes R1 to R3 and the link coupling portion A46j, the adjustment hole R1 is the shortest, the adjustment hole R3 is the longest, and the adjustment hole R2 is an intermediate length between the adjustment holes R1 and R3.

  As a result, the interval at which the left and right binding claws 41z approach in the E direction can be adjusted. Accordingly, the adjustment hole R1 is used when the small-diameter binding component is used because the left and right binding claws 41z are closest to each other in the E direction, and the adjustment hole R2 is used when the medium-diameter binding component is used. The adjustment hole R3 is used when a large-diameter binding component is used.

  Further, the distance H2 between the avoidance hole R4 and the link coupling portion A46j is set to be extremely longer than any of the adjustment holes R1 to R3 (the distance H1 in the drawing represents the distance of the adjustment hole R3). This is to make the process from the binding start position to the binding completion position substantially zero. That is, even when the binding claw cam 41p shown in FIG. 6 (A) rotates, the binding claw cam 41p idles because the link coupling portion B46k of the binding claw link C41n is set in the avoidance hole R4. No downward force is applied to the binding claw link B41m. Accordingly, no force is transmitted to the left and right binding claws link A41l, and the left and right binding claws 41z are not closed in the direction indicated by the arrow E. Thereby, when the no-load mode is set, the process of binding the binding claw 41z can be stopped, so that the binding component 43 bound by the binding claw 41z can be released halfway and the binding mechanism 41 is moved to the home position. It becomes possible to shift to the process for making it wait. Here, the no-load mode refers to an operation of setting the binding stroke in a state where the binding claw 41z is not moved in the E direction to substantially zero and waiting for the binding process.

  FIG. 7 is a cross-sectional view illustrating an internal configuration example (No. 2) of the binding mechanism 41. The binding mechanism 41 shown in FIG. 7 has the same configuration as the binding mechanism 41 shown in FIG. 6A, and is transitioned from the state of FIG.

  In this example, the binding component adjusting portion 46l is moved from the position shown in FIG. 6A to the right position shown in FIG. 7 by the rotated binding component adjusting cam 41u, and the adjusting portion 46l. The binding claw link B41m connected to the right side also moves to the right. At this time, the binding claw link B coupling hole 41s of the link B41m also moves in the same manner. As a result, the projecting link coupling to the avoidance hole R4 (see FIG. 6B) of the coupling hole 41s that sets the binding stroke to substantially zero. Part B46k is set.

  In this way, the link coupling portion B46k is set in the avoidance hole R4. After the setting, the distance between the avoidance hole R4 and the link coupling portion A46j becomes the distance H2 shown in FIG. 6B. As described above, the binding claw cam 41p idles and the left and right binding claws 41z are moved to the arrow E. It cannot be closed in the direction shown. Thereby, since the process which binds the binding claw 41z can be stopped, it becomes possible to shift to the subsequent process.

  FIGS. 8A and 8B are cross-sectional views showing an internal configuration example (No. 3) of the binding mechanism 41, and configuration examples and operation examples of related members in the binding component gripping portion 41b (when moving up and down). Indicates.

  Since the binding mechanism 41 shown in FIG. 8A moves the binding component gripping portion 41b up and down, for example, the gripping portion link 41f, the gripping portion cam 41g, the gripping portion link rotating shaft 41j, and the binding mechanism driving motor 45a. (See FIG. 10). In this example, the binding component gripping portion 41b is shown in the lowermost position.

  The binding component gripping portion 41b has a predetermined height, and the width in the horizontal direction and the vertical direction is slightly smaller than that of the opening portion 41c. In addition, a plurality of binding component gripping claws 41h for gripping the binding component are provided at the upper end of the binding component gripping portion 41b.

  Further, the binding component gripping portion 41b has a protruding gripping portion link coupling portion 41e on the side surface. The binding component gripping portion 41b and the gripping portion link 41f are in a state where the gripping portion link coupling portion 41e is fitted and coupled to the long hole-shaped gripping portion coupling hole 41I of the gripping portion link 41f. The grip portion link 41f is connected to the grip portion cam 41g, and is configured to be rotatable about the grip portion link rotation shaft 41j by rotating the grip portion cam 41g.

  The binding mechanism 41 shown in FIG. 8B shows a case where the binding component gripping portion 41b has moved from the state located at the lowermost part shown in FIG. 8A to the state located at the uppermost part. In this case, the gripping part link 41f rotates as the gripping part cam 41g rotates. As a result, the position and posture of the grip portion coupling hole 41I change, and as a result, the binding component grip portion 41b can be moved upward as indicated by the arrow D via the grip portion link coupling portion 41e. The

  As described above, the binding component gripping portion 41b is configured to be movable from the lowermost portion shown in FIG. 8A to the uppermost portion shown in FIG. 8B. Further, in the state where the binding component gripping portion 41b shown in FIG. 8A is positioned at the lowermost position, the binding component gripping claw 41h is positioned inside the main body portion 41a. Further, as shown in FIG. 8B, in a state where the binding component gripping portion 41b is positioned at the uppermost portion, the binding component gripping claw 41h is positioned outside the main body portion 41a.

  Next, a configuration example of the binding component 43 will be described. 9A to 9D are explanatory diagrams illustrating a configuration example of the binding component 43. FIG. A binding component 43 shown in FIG. 9A is a plan view showing a part of the binding component 43. The binding component 43 includes a spine portion 43a, a first split ring portion 43d, a second split ring portion 43c, a third split ring portion 43e, a pin 43f, a first connecting portion 43g, and a second connecting portion 43h. Have. The binding component 43 is a resin injection molded product in which ring portions 43b are arranged at regular intervals on a spine portion 43a having a length that matches the size of the standard paper.

  FIG. 9B is a diagram illustrating a state viewed from an arrow B in FIG. As shown in FIGS. 9A and 9B, the ring portion 43b includes a split ring portion 43c coupled to the spine portion 43a and a split ring portion 43d and a split ring portion 43e that are foldably connected to the left and right thereof. It is divided into three parts.

  A coupling portion 43g is provided at the tip of the split ring portion 43d, and a joint portion 43h is provided at the tip of the split ring portion 43e. The coupling portion 43g and the coupling portion 43h are coupled, so that the ring portion 43b is annular.

  FIG. 9C is a cross-sectional view taken along the line CC in FIG. The shape of the cross section of the spine 43a of the binding component 43 shown in FIG. 9C is a convex shape, and this convex shape is for making it easy to grip the binding component 43 with the binding component gripping claws 41h having an inverted L-shape. Shape.

  FIG. 9D shows a state in which a plurality of binding components 43 are stacked as viewed from an arrow B in FIG. Further, as shown in FIGS. 9A to 9C, the split ring portion 43c of the ring portion 43b has a protruding pin 43f. An insertion hole (not shown) corresponding to the pin 43f is provided on the opposite side of the split ring portion 43c provided with the pin 43f. As a result, the plurality of binding components 43 can be stacked by inserting the pins 43f into the insertion holes in a state where both end portions of the split ring portion 43d, the split ring portion 43c, and the split ring portion 43e are aligned. .

  Note that a plurality of types of binding components 43 are used in which the size of the ring portion 43b differs depending on the thickness of the sheet bundle 3 ″ shown in FIG. 2. Also, the binding portion 43 is divided into the ring portions 43b. Although the ring portion 43d, the divided ring portion 43c, and the divided ring portion 43e are divided into three locations, the ring portion 43b may be divided into n (n is a natural number) locations.

  FIG. 10 is a block diagram illustrating a configuration example of a control system of the bind processing unit 40. The control system shown in FIG. 10 includes a control unit 50, a motor drive unit 44a, and a signal processing unit 44b.

  The control unit 50 includes a system bus 55. The system bus 55 includes an I / O port 54, an EEPROM (Erasable Programmable Read Only Memory) 53, a RAM (Random Access Memory) 52, and a CPU (Central Processing Unit). ) 51 is connected. The EEPROM 53 has a program (binding component acquisition control program) for controlling the operation in which the binding mechanism 41 acquires the binding component 43 and binds the binding component 43 to a sheet, and the binding start of the binding mechanism 41 processing the binding component 43. The elapsed time (target time) from the time to the binding completion time is stored. The RAM 52 is used as a work memory when acquiring and controlling the binding component 43 based on the binding component acquisition control control program.

  The I / O port 54 is connected to a motor driving unit 44a and a signal processing unit 44b. A binding component size sensor 45f and an external terminal are connected to the signal processing unit 44b. For example, a reflective optical sensor is used as the binding component size sensor 45f. The binding component size sensor 45f detects the size of the lowermost binding component 43 stored in the binder cassette 42 and outputs the binding component size signal S45f to the signal processing unit 44b. The signal processing unit 44b receives the output binding component size signal S45f, digitizes the binding component size signal S45f, and outputs, for example, 3-bit detection data to the CPU 51. The method for detecting the size of the binding component 43 is, for example, detecting that a difference occurs in a location where the binding component 43 contacts the binder cassette 42 due to a difference in size of the binding component 43.

  In addition, a copy machine (not shown) is connected to the external terminal. For example, information on the number of sheets for one booklet printed by a copier combined with the binding apparatus 100 is output from the external terminal to the signal processing unit 44b as the specified number of sheets signal S45g, and the signal processing unit 44b outputs the information. The specified number signal S45g is binarized and the detection data Dp is output to the CPU 51.

  The CPU 51 constitutes an example of a control unit, inputs detection data Dp, and based on the detection data Dp, when a sheet 3 ′ of one booklet is accumulated in the paper alignment unit 30 shown in FIG. If it judges, motor control data Dm will be output to the motor drive part 44a, and it will control so that the binding mechanism 41 performs a binding process.

  The motor driving unit 44a is connected to the CPU 51 via the I / O port 54, and is further connected to a binding mechanism driving motor 45a and a binding component adjusting motor 45b disposed in the binding mechanism 41.

  The motor drive unit 44a receives the motor control data Dm output from the CPU 51, outputs a binding mechanism drive signal S45a obtained by decoding the motor control data Dm to the binding mechanism drive motor 45a, and drives the motor 45a. 8, the binding component gripping portion 41b shown in FIG. 8 is moved upward to a position where the binding component 43 of the lowest layer stacked on the binder cassette 42 can be acquired.

  After the binding component gripping portion 41b moves upward to a position where the binding component 43 can be acquired, the binding component gripping claw 41h is opened and closed to acquire the binding component 43. After acquiring the binding component 43, the binding component gripping portion 41b is moved downward.

  After moving downward, the CPU 51 inputs size information of the binding component 43 from a sensor (not shown) installed in the binder cassette 42 shown in FIG. The CPU 51 outputs motor control data Dm to the motor drive unit 44a based on the input size information. The motor drive unit 44a receives the output motor control data Dm, and outputs a binding component adjustment signal S45b obtained by decoding the motor control data Dm to the binding component adjustment motor 45b. The binding component adjustment motor 45b constitutes an example of a drive unit, receives a binding component adjustment signal S45b, and drives the binding component adjustment cam 41u shown in FIG. 6 in accordance with the diameter size of the binding component 43. The binding stroke of the binding claw 41z is adjusted.

  After adjusting the binding stroke, the motor 45a rotates the binding mechanism 41 from the direction II shown in FIG. 3 to the position in the direction I shown in FIG. After the rotation, by driving the motor 45a, the sheet 3 ″ shown in FIG. 2 is provided from the binder paper alignment unit 30 to the binding mechanism 41, and the binding pawl cam 41p shown in FIG. 6A is rotated. Then, the binding claw 41z is bound and the binding component 43 is bound to the punch hole of the paper 3 ". Thereafter, the binding mechanism 41 releases the binding component 43 and moves to the home position shown in FIG. In this way, the binding apparatus 100 creates the booklet 90 by binding the binding component 43 to the paper 3 ″ provided from the binder paper alignment unit 30.

  Further, the CPU 51 measures the processing time of the binding component 43 in the binding mechanism 41, compares the measured processing time with the set target time, and if the processing time exceeds the target time, the CPU 51 Set no-load mode. The processing time of the binding component 43 actually means an elapsed time from the binding start time when the binding mechanism 41 processes the binding component 43 to the binding completion time. As for the binding start time, for example, the CPU 51 determines that the sheet 3 'for one booklet will be accumulated in the paper aligning unit 30 shown in FIG. It is time to start processing. The binding completion time is the time when the binding component 43 is bound to the paper 3 ″ and returned to the home position.

  When the no-load mode is set, the CPU 51 outputs the motor control data Dm for setting the no-load mode to the motor driving unit 44a. The motor drive unit 44a receives the output motor control data Dm, and outputs a binding component adjustment signal S45b to the binding component adjustment motor 45b. The binding component adjusting motor 45b inputs the signal S45b and rotates the binding component adjusting cam 41u shown in FIG. The binding component adjusting cam 41u is rotated to move the binding component adjusting portion 46l to the right in FIG. 6, and the binding claw link B41m connected to the adjusting portion 46l is moved to the right. The At this time, the binding claw link B coupling hole 41s of the link B41m is simultaneously moved rightward, and the avoidance hole R4 shown in FIG. 6B of the coupling hole 41s that sets the binding stroke to substantially zero has a protruding shape. The link coupling part B46k is set. As a result, the binding claw cam 41p for binding the binding claw 41z shown in FIG.

  Thereby, since the binding process can be stopped while the no-load mode is set, the process can be shifted to a process for making the binding mechanism 41 stand by to the home position. Accordingly, the binding device 100 can be prevented from falling into a locked state. As a result, the user can easily remove the binding component 43 or the booklet with poor binding from the apparatus 100 using the period in which the no-load mode is set.

  The binding mechanism 41 returns the link coupling part B46k set in the avoidance hole R4 to the adjustment hole that was originally set after returning to the home position. For example, the CPU 51 outputs motor control data Dm for releasing the no-load mode to the motor driving unit 44a. The motor drive unit 44a receives the output motor control data Dm, and outputs a binding component adjustment signal S45b to the binding component adjustment motor 45b. The binding component adjusting motor 45b inputs the signal S45b and rotates the binding component adjusting cam 41u shown in FIG. The binding component adjustment portion 461 is moved leftward as viewed in FIG. 7 by the rotated binding component adjustment cam 41u, and the binding claw link B41m connected to the adjustment portion 461 is moved leftward. The At this time, the binding claw link B coupling hole 41s of the link B41m is also moved leftward at the same time, and the protruding link coupling part B46k is set in the adjustment hole shown in FIG. 6B of the coupling hole 41s. . As a result, the no-load mode can be canceled.

  Next, an example of taking out the binding component 43 by the binding mechanism 41 will be described. 11A to 11D are process diagrams illustrating an example of taking out the binding component 43 by the binding mechanism 41. FIG. In this example, an operation example of the related member on the cut surface of the binding mechanism 41 illustrated in FIG. 8 will be described. It is assumed that one binding component 43 is separated from the binder cassette 42 in a state where the binding mechanism 41 is in the binding component take-out position under the binder cassette 42, and the binding component 43 is taken out and put into the half-binding state. And In this step, rotation to the binder paper alignment unit 30 is not performed.

  The binding component gripping part 41b shown in FIG. 11 (A) is in a state of being located at the lowermost part. A binding component 43 is set in the binder cassette 42. 8A, the motor 45a shown in FIG. 10 rotates the gripping part cam 41g, and the gripping part link 41f rotates by the rotation of the gripping part cam 41g. As a result, the position and posture of the grip portion coupling hole 41I change, and as a result, the binding component grip portion 41b moves upward via the grip portion link coupling portion 41e.

  After moving upward, when the binding component gripping portion 41 b shown in FIG. 11B reaches the binding component 43, the binding component gripping claw 41 h is closed and the spine portion 43 a of the binding component 43 is gripped. At this time, the binding component gripping claw 41h is in a state where only one binding component 43 is gripped. In this state, the motor 45a rotates the gripping part cam 41g, and the gripping part cam 41g rotates to move the binding part gripping part 41b that grips the binding part 43 downward.

  After the binding component 43 is taken out from the binder cassette 42, when the binding component gripping portion 41b is moved downward, the binding component 43 comes into contact with the binding claw 41z as shown in FIG. At this time, the binding claw 41z is in an open state. Thereafter, the binding component gripping portion 41b is moved further downward with the binding claw 41z opened. At this time, as shown in FIG. 11D, when the split ring portions 43d and 43e (see FIG. 9) of the binding component 43 are pushed by the binding claw 41z, the binding component 43 is bent by a predetermined amount and half-bound. (This operation is referred to as first forming of the binding component 43).

  Subsequently, after the first forming, the binding component 43 is bound by the binding mechanism 41 on the paper 3 ″ provided from the binder paper alignment unit 30, and the tip of the binding component 43 is mistakenly punched by the punch hole of the paper 3 ″. An example of inserting and fitting in a place other than 3a will be described. As a possibility of inserting in a place other than the punch hole 3a, there are a case where the punch hole 3a of the sheet 3 ″ is not prepared or a case where a defect occurs during the first forming of the binding component 43.

  12A to 12D are process diagrams showing an operation example when the no-load mode is set. In this example, an operation example of the related member on the cut surface of the binding mechanism 41 illustrated in FIG.

  For example, when the binding mechanism 41 binds the binding component 43 to the punch hole 3a of the booklet 3 ″ to create the booklet 90, the component gripping claw 41h correctly aligns the spine 43a of the binding component 43 shown in FIG. It is assumed that there is a defect in the first forming, and the target time is usually set to 4 seconds when the processing time for processing the binding component 43 is about 1.5 seconds. The target time is set in the binding mechanism 41, and the target time is stored in the EEPROM 53. In this example, the processing time (1.5 seconds) is the state shown in FIG. ) To the home position (direction II) shown in FIG. 3 after the binding component 43 is bound to the sheet bundle 3 ″.

  As conditions for controlling the binding failure of the binding mechanism 41, first, the binding mechanism 41 shown in FIG. 11D is rotated to the paper binding position (direction I) of the binding mechanism 41 shown in FIG. Move. At this time, the CPU 51 starts measuring the processing time from the first forming until the binding component 43 is bound to the sheet bundle 3 ″ and returned to the home position.

  The binder sheet aligning unit 30 (not shown) lowers the sheet bundle 3 ″ and directs the sheet bundle 3 ″ toward the center of the binding component 43 in the half-bound state provided by the bind processing unit 40 as shown in FIG. Move. Thereafter, when the punch hole (hole 3a) of the sheet bundle 3 ″ reaches the fitting position of the front end portion of the binding component 43 in the half-stitched state, the binding mechanism 41 causes the binding claw as shown in FIG. 41z is closed, and the coupling portions 43g and 43h of the binding component 43 shown in FIG. 9B are bound to each hole 3a of the sheet bundle 3 ″.

  At this time, as described above, a defect occurred in the first forming, so that the coupling portions 43g and 43h of the binding component 43 were not partially fitted in the respective holes 3a of the sheet bundle 3 ″, and the binding claw cam 41p was In this case, the binding claw 41z cannot be completely bound, and the binding mechanism driving motor 45a shown in Fig. 10 rotates the binding claw cam 41p. The operation of binding the binding claw 41z is continued.

  At this time, the CPU 51 compares the processing time from the start of measurement with the target time (= 4 seconds), and outputs the motor control data Dm to the motor driving unit 44a when the processing time exceeds 4 seconds. The motor driving unit 44a outputs a binding mechanism driving signal S45a to the binding mechanism driving motor 45a. The motor 45a reversely rotates the binding claw cam 41p to return to the state before the binding claw 41z starts to move, and at the same time as releasing the load, the jammed binding component 43 is easily taken out.

  Subsequently, the CPU 51 outputs motor control data Dm for setting the no-load mode to the motor driving unit 44a. The motor drive unit 44a receives the motor control data Dm and outputs a binding component adjustment signal S45b to the binding component adjustment motor 45b.

  The binding component adjustment motor 45b receives the binding component adjustment signal S45b, and rotates the binding component adjustment cam 41u as shown in FIG. The binding component adjusting portion 461 moves rightward toward FIG. 12D by the rotated binding component adjusting cam 41u, and the binding claw link B41m connected to the adjusting portion 461 also moves rightward. Move to. At this time, the binding claw link B coupling hole 41s of the link B41m also moves in the same manner. As a result, the projecting link coupling to the avoidance hole R4 (see FIG. 6B) of the coupling hole 41s that sets the binding stroke to substantially zero. Part B46k is set.

  After setting the link coupling portion B46k in the avoidance hole R4, the motor driving unit 44a outputs the binding mechanism driving signal S45a to the binding mechanism driving motor 45a. The motor 45a rotates the binding claw cam 41p in the forward direction. At this time, since the link coupling portion B46k is set in the avoidance hole R4 that sets the binding stroke to substantially zero, the binding claw cam 41p rotates idly. Thereby, the process of binding the binding claw 41z can be stopped, and the binding part gripping claw 41h shown in FIG. 12D can be opened to release the spine 43a of the binding part 43. After the release, the binding mechanism 41 rotates with reference to the binding mechanism rotation shaft 41d shown in FIG. 3 and returns to the home position (direction II). After returning to the home position, the binding mechanism 41 sets the link coupling portion B46k to the adjustment hole originally set from the avoidance hole R4.

  The binder sheet aligning unit 30 pulls up the booklet 90 ′ with the binding component 43 bound halfway as shown in FIG. 12D to the upstream side and drops the booklet 90 ′ onto the belt unit 61. The belt unit 61 receives the booklet 90 'that has been dropped and ends the process. At this time, the message “Please remove the defective booklet on the discharge path” is displayed on the monitor of a copier (not shown) used side by side in the apparatus 100. The user who has confirmed this display removes the booklet 90 ′ dropped on the belt unit 61. As a result, the binding component 43 and the booklet 90 ′ with poor binding can be easily removed from the apparatus 100.

  As described above, according to the binding device 100 and the sheet processing method as the embodiment, a booklet is created by binding the binding component 43 into a hole punched in a predetermined position of each of a plurality of sheets, and is measured. The CPU 51 controls the binding mechanism 41 based on the result of comparing the processing time of the binding component 43 and the set target time. The CPU 51 is configured to control the binding mechanism 41 when the processing time exceeds the target time. Is set to no-load mode.

  Therefore, since the process of binding the binding claw 41z of the binding mechanism 41 can be stopped while the no-load mode is set, the binding mechanism 41 is made to stand by to the home position even when a binding process failure occurs. It becomes possible to shift to processing. As a result, the apparatus 100 can be prevented from falling into the locked state, so that the user can easily remove the binding component 42 and the booklet 90 ′ having poor binding from the apparatus 100.

  A lever that forcibly releases the binding component 43 may be provided. When the user releases the lever, the binding component gripping claws 41h and the binding claws 41z are forcibly opened. Further, the binding part gripping claws 41h and the binding claws 41z may be configured to operate by separate driving sources, and the control part 50 may control the opening of the binding part gripping claws 41h and the binding claws 41z in the no-load mode. . In this way, the binding component 43 can be released from the binding mechanism 41.
