  Here, a binding operation example of the binding component 43 will be described. FIGS. 10A to 10C are state transition diagrams illustrating an example of the binding operation of the binding component 43. FIG. The binding component 43 shown in FIG. 10A is in a state where the ring portion 43b is unfolded, as seen from the arrow B in FIG. 8A. The binding component 43 shown in FIG. 10A has a ring portion 43b. The ring portion 43b includes a ring portion A43d, a ring portion B43c, and a ring portion C43e each having an arc shape. The ring part A43d and the ring part B43c are connected by a connecting part, and the ring part B43c and the ring part C43e are connected by a connecting part.

In this example, the connecting portion between the ring portion A43d and the ring portion B43c and the connecting portion between the ring portion B43c and the ring portion C43e are configured to be bendable. For example, as shown in FIG. 10A, from the state in which each end of each of the ring part A43d, the ring part B43c, and the ring part C43e is developed (aligned) on a substantially straight line,
10B, the ring part A43d and the ring part C43e are further bent to join the joint part A43g and the joint part B43h. Thereby, as shown in FIG.10 (c), the binding component 43 comprises a perfect ring shape.

  The coupling portion A43g and the coupling portion B43h can be coupled and detached many times, and the binding component 43 can be reused. Also, a plurality of binding components 43 described in FIGS. 8, 9 and 10 are different in the size of the ring portion 43b depending on the size of the paper 3 (paper width size) and the thickness of the paper bundle 3 ″. Each type is used, and each time the cartridge 42 is replaced or the binding component 43 is re-stored in the cartridge 42.

  FIG. 11 is a side view supplementing a configuration example of the cartridge loading mechanism 40. According to the cartridge loading mechanism 40 shown in FIG. 11, the cartridge 42 that houses (sets) the stacked binding components 43 (stacked binding ring) shown in FIG. 9 is loaded in the cartridge loading mechanism 40. In this example, the left frame 4L (front side in the figure) shown in FIG. 5 is removed from the cartridge loading mechanism 40 to make the structure of the upper part of the pusher 403 easier to see.

  In FIG. 11, the cartridge loading mechanism 40 has a first pusher link 411. For the pusher link 411, a long metal plate reinforced on both sides is used. An operation door 407 is rotatably engaged with the pusher link 411. For example, one end of the pusher link 411 and the operation door 407 are pivotally supported by the pivot pin 428.

  The operation door 407 is pivotally supported by a pivot pin 427 with respect to the bottom member 4b. One end of the operation door 407 is bent at 90 ° and is operated to transmit an upward force to the pusher link 411. A handle 4 e is provided on a predetermined surface side of the other end of the operation door 407. When the handle 4e is pulled to the right side in the drawing, the operation door 407 is opened, and the pusher link 411 is pushed upward with the pivot pin 427 as the center of rotation. On the other hand, when the handle 4e is pushed back to the left in the drawing from the state in which the operation door 407 is opened, the pusher link 411 is lowered downward with the pivot pin 427 as the center of rotation.

  The second pusher link 412 is rotatably engaged with the first pusher link 411. For example, the pusher link 411 and the pusher link 412 are pivotally supported in a T shape by the pivot pin 429 near one end of the pusher link 411 and the entire length of the pusher link 412. One end of the pusher link 412 is pivotally supported on a left frame 4L (not shown) by a pivot pin 442.

  A contact pin 441 is provided upright at the other end of the pusher link 412. The left frame 4L is provided with an arcuate slot 432 that guides the contact pin 441. In this example, the upper surface of the pusher link 412 on the contact pin 441 side is engaged with the pantograph structure 410 for moving the pusher 403 up and down. When the handle 4e is pulled to the right in the figure, the operation door 407 is opened, and the pusher link 411 pushed up with the pivot pin 427 as the pivot center moves the pusher link 412 with the pivot pin 442 as the pivot center. Push up. As a result, the pusher 403 can be forced upward through the pantograph structure 410.

  On the other hand, when the handle 4e is pushed back to the left in the figure from the state in which the operation door 407 is opened, the pusher link 411 pushed down with the pivot pin 427 as the center of rotation pushes the pusher link 412 downward. . As a result, the downward movement of the pusher 403 via the pantograph structure 410 is free.

  A first holder link 413 and a second holder link 414 are rotatably engaged on the left and right above the pusher 403. For example, for the holder link 413, a long metal plate reinforced on both sides is used, and a long hole portion 433 is provided at the center. One end of the holder link 413 is pivotally supported by a pivot pin 421 on the left side of the pusher 403. The holder link 414 is also made of a long metal plate reinforced on both sides, and has a long hole 434 at the center. One end of the holder link 414 is pivotally supported by a pivot pin 424 on the right side of the pusher 403.

  In this example, a long hole portion 437 is opened at a predetermined position on the right frame 4R (the back side in the drawing) in a straight line in the vertical direction. The long hole part 433 of the holder link 413 and the long hole part 434 of the holder link 414 are pivotally supported by the shaft support pin 427 with respect to the long hole part 437.

  Further, the fourth holder link 416 is rotatably engaged with the third holder link 413. For example, the other end of the holder link 413 and the other end of the holder link 416 are pivotally supported by the pivot pin 425. A long metal plate reinforced on both sides is also used for the holder link 416, and a long hole 436 is provided at the center.

  The holder link 415 is rotatably engaged with the above-described holder link 414. For example, the other end of the holder link 414 and the other end of the holder link 415 are pivotally supported by the pivot pin 422. A long metal plate reinforced on both sides is also used for the holder link 414, and a long hole 434 is provided at the center.

  The other end of the holder link 415 is pivotally supported on the right frame 4R by a pivot pin 426 at the upper right part of the right frame 4R (back side in the figure). The other end of the holder link 416 is pivotally supported on the right frame 4R by a pivot pin 423 at the upper left portion of the right frame 4R. The long hole part 435 of the holder link 415 and the long hole part 436 of the holder link 416 are pivotally supported by the long pin part 437 by a pivot pin 428.

  A pin 445 protrudes from a plate member provided with the shaft support pin 428 at a position below the shaft support pin 428, and the upper surface of the pusher link 412 is engaged with the pin 445, so that the operation door 407 is attached. By performing the opening operation, the pantograph structure 410 opens and closes, and the pusher 403 is pulled up.

  As a result, the pantograph structure 410 that holds the pusher 403 can be arranged in the upper region in the cart frame 401. According to the pantograph structure 410, the holder link 413, the holder link 414, the holder link 415, and the holder link 416 can be expanded and contracted in an X shape with reference to the elongated hole portion 437, and the pusher 403 is formed on the upper portion of the cart frame 401. Is made to lift. In the drawing, one end of the tension spring 406 is connected to the movable pin 404, but the other end shows a state in which the left frame 4L has been removed and is removed from the protrusion 4d.

  12 to 15 are side views showing an operation example of the cartridge loading mechanism 40. FIG. 12 is a side view showing a pressing example (No. 1) of the pusher 403. The binding component 43 is sequentially pulled out from the cartridge 42 shown in FIG. 11, and the binding component 43 remains in the cartridge 42.

  According to the pantograph structure 410 of the cartridge loading mechanism 40, the contact pin 441 of the pusher link 412 and the holder link 415 are brought into a non-contact state, and the holder links 413, 414, 415 are based on the long hole portion 437. , 416 are extended in an X shape extending vertically, and the pusher 403 is lifted from the upper portion of the cart frame 401.

  FIG. 13 is a side view showing a pressing example (No. 2) of the pusher 403. The pusher 403 shown in FIG. 13 is a state in which the binding component 43 is further consumed from the component consumption state shown in FIG. 12 and the last binding component 43 is pressed in the cartridge 42. According to the pantograph structure 410 at this time, the contact pin 441 of the pusher link 412 and the holder link 415 are brought into a non-contact state, and the holder links 413, 414, 415 are based on the straight long hole portion 437. , 416 are extended in an X shape extending vertically, and the pusher 403 is lifted from the upper portion of the cart frame 401.

  13 and 14 are side views showing an example of opening operation of the operation door 407 in the cartridge loading mechanism 40. FIG. When the handle 4e shown in FIG. 14 is pulled to the right side in the drawing, the operation door 407 opens, and the pusher link 411 pushed up with the pivot pin 427 as the pivot center moves the pivot pin 442 as the pivot center. Pusher link 412 is pushed upward. As a result, the pusher 403 can be forced upward through the pantograph structure 410.

  According to the pantograph structure 410 at this time, the abutment pin 441 of the pusher link 412 is abutted against the semicircular arc-shaped recess 445 of the holder link 415, and the holder links 413, 414, 415 are based on the long hole portion 437. , 416 are shortened into an X shape that is vertically packed, and the pusher 403 is lifted from the upper portion of the cart frame 401.

  At this stage, the movable pin 404 pushed up to the uppermost end of the long hole portion 405 maintains the posture of being fitted to the pin hooking portion 408, so that the cartridge 42 is continuously locked to the cart frame 401. (Upper end locking mechanism).

  When the cartridge 42 is strongly pulled out to the right from this state, the upper end lock mechanism is released. At this time, when an external force exceeding the mountain shape of the pin hooking portion 408 is applied to the movable pin 404, the lock can be released (upper end lock release mechanism). In addition, the movable pin 404 is biased by the tension spring 406 and moves to the lowermost end of the long hole portion 405.

  FIG. 15 is a side view showing a lock example of the pusher 403. According to the cartridge loading mechanism 40 shown in FIG. 15, the cartridge 42 is pulled out while the operation door 407 shown in FIG. 14 is open, and the operation door 407 is closed without being loaded. is there. In this case, when the handle 4e is pushed back to the left side in the drawing from the state where the operation door 407 is opened, the pusher link 411 pushed down with the pivot pin 427 as the rotation center pushes the pusher link 412 downward. As a result, the pusher 403 can freely move downward.

  However, in this example, as a safety measure, even if the operation door 407 is closed with respect to the cart frame 401 with the cartridge 42 removed, the movable pin 404 locks the pusher 403 as shown in FIG. It has become. This is because the tension spring 406 attached between the protrusion 4d of the left frame 4L and one end of the movable pin 404 urges the movable pin 404 toward the lowermost end of the long hole portion 405. Thereby, when the cartridge 42 is not loaded, the movable pin 404 can protrude into the guide groove portion 402, so that the pusher 403 can be prevented from dropping and the pusher pressing operation can be restricted (lower end lock mechanism).

  FIG. 16 is a block diagram illustrating a configuration example of a control system in the binding device 100. A control unit 50 is provided in the binding device 100 shown in FIG. As the control unit 50, a microcomputer provided with a CPU, RAM, ROM and the like (not shown) is used.

  For example, a paper feed sensor 111, paper detection sensors 114 and 118, and a consumable sensor 119 are connected to the input side of the control unit 50. To the output side, for example, motor drive units (not shown) of each of the paper transport unit 10, the punch processing unit 20, the paper alignment unit 30, the moving mechanism 41, and the discharge unit 60 are connected.

  The paper feed sensor 111 detects the leading edge of the paper 3 on the first transport path 11 and outputs a paper feed control signal S11 to the control unit 50. The paper detection sensor 114 detects the front and rear ends of the paper 3 and outputs a paper detection signal S14 to the control unit 50. The paper transport unit 10 transports the paper 3 drawn from the paper feed port 13 toward the discharge port 14 or the second transport path 12 based on the paper transport control signal S10. The paper transport control signal S10 is output to the paper transport unit 10 from the control unit 50 that has input the paper feed control signal S11, the paper detection signal S14, and the like.

  In the punch processing unit 20, the motor 22 shown in FIG. 1 is driven based on the punch control signal S20, and the punch blade 21 is reciprocated. The sheets 3 are punched one by one by a punch blade 21 driven by a motor 22. The punch control signal S20 is output from the control unit 50 to the punch processing unit 20. The paper detection sensor 118 detects the front and rear edges of the punched paper 3 ′ and outputs a paper detection signal S 18 to the control unit 50.

  The paper alignment unit 30 drives the paddle roller unit 32, the side jogger, etc. based on the paper alignment control signal S30 to align the plurality of paper bundles 3 ″. The paper alignment control signal S30 is a control unit 50. 16 is output to the paper alignment unit 30. A consumable sensor 119 shown in Fig. 16 detects the remaining amount of the binding component 43 in the cartridge shown in Figs. Is output.

  The moving mechanism 41 reciprocates between the binding component take-out position and the paper binding position based on the movement mechanism control signal S41. The movement mechanism control signal S41 is output to the movement mechanism 41 from the control unit 50 that has received the consumable item detection signal S19. Further, the moving mechanism 41 operates to take out the binding component 43 from the cartridge loading mechanism 40 and to bind one side of the sheet bundle 3 ″ with the binding component 43 in cooperation with the clamp moving mechanism 80 of the paper aligning unit 30. The sheet bundle 3 ″ bound with the component 43 becomes a booklet 90. The discharge unit 60 discharges the booklet 90 created by the bind processing unit 400 based on the discharge control signal S60. Thus, a control system in the binding device 100 is configured.

  Next, an example of handling the cartridge 42 in the binding device 100 will be described. FIG. 17 is a flowchart showing an example of handling the cartridge 42.

  In this example, when the cartridge 42 is loaded on the cart frame 401 in the cartridge loading mechanism 40 shown in FIG. 11, the lock function by the movable pin 404 is released. As a result, the pusher 403 presses the binding component 43 in the cartridge 42 from above.

  Under these handling conditions, the cartridge 42 is loaded into the cartridge loading mechanism 40 in step ST1 of the flowchart shown in FIG. At this time, the cartridge 42 is loaded into a loading area defined in the cart frame 401. In the cartridge loading mechanism 40, the movable pin 404 is pushed up by the surface on the insertion end side of the cartridge 42, and the movable pin 404 is retracted along the long hole portion 405.

  In this example, the movable pin 404 receives an external force from the side and loses the escape field, and overcomes the biasing force of the tension spring 406 and moves upward along the shape of the elongated hole portion 405 having a square shape. In this way, the movable pin 404 can be moved upward from the guide groove portion 402, so that the dropping operation of the pusher 403 can be released thereafter (see FIG. 11: lower end lock release mechanism).

  Next, it transfers to step ST2 and performs a binding process. For example, the bind processing unit 400 shown in FIG. 3 creates a booklet 90 by binding a plurality of sheet bundles 3 ″ aligned by the sheet aligning unit 30 with the binding component 43 in cooperation with the sheet aligning unit 30. To be made.

  At this time, at the position where the opening 41c of the moving mechanism 41 faces the cartridge 42 side, from the binding component 43 in the stacked state as shown in FIG. The binding component 43 is received. The moving mechanism 41 that has received the binding component 43 changes the form of the binding component 43 so as to be in a half-binding state as shown in FIG.

  Thereafter, the moving mechanism 41 shown in FIG. 4 rotates from the binding component take-out position to the paper binding position as indicated by an arrow A with reference to the moving mechanism rotation shaft 41d. The rotation control of the moving mechanism 41 is executed by driving a motor for rotating the moving mechanism based on a motor control signal by a control system (not shown). In the paper aligning unit 30, at a paper binding position, a clamping mechanism (not shown) binds the paper bundle with the binding component 43 in cooperation with the moving mechanism 41. At this time, as shown in FIG. 10C, the binding component 43 forms a complete ring shape (automatic bookbinding function).

  Further, in step ST3, it is determined whether or not all the binding components 43 have been used. The determination at this time is performed by the control unit 50 based on the consumable item detection signal S19 (remaining amount detection information) from the consumable item sensor 119 for detecting the remaining amount of the binding component 43 (not shown). Judgment is made whether or not all of them have been used. When all of the binding parts 43 are used, the control unit 50 may display the information. If a message to that effect is displayed, the process proceeds to step ST4, and the cartridge 42 is taken out from the cartridge loading mechanism 40. At this time, the movable pin 404 moves to the lower part along the shape of the guide groove portion 402 after the cartridge 42 is sequentially pulled out after passing the pin hooking portion 408 and the urging force of the tension spring 406. go. The movable pin 404 comes to support the pusher 403 at the place where it is lowered.

  Thereafter, the process proceeds to step ST5, where the binding component 43 is stored in the cartridge 42. At this time, the user stacks the binding components 43 as shown in FIG. 8 a as shown in FIG. 9 and stores them in the cartridge 42 having no top surface. Then, returning to step ST1, the cartridge 42 is loaded into the cartridge loading mechanism 40. At this time, in the cartridge loading mechanism 40, the movable pin 404 is pushed up on the surface on the insertion end side of the cartridge 42, and the movable pin 404 is retracted along the long hole portion 405. In this way, the movable pin 404 can be moved upward from the guide groove 402, so that the dropping operation of the pusher 403 can be released thereafter (lower end lock release mechanism). Thereafter, the above-described processing is repeated.

  As described above, according to the cartridge loading mechanism and the paper processing apparatus according to the present invention, when the plurality of binding components 43 are stacked and the binding components 43 are supplied from the bottom, the loading area is set by the cart frame 401. A left and right frame 4L, 4R to be defined is provided with a rectangular guide groove 402. The pusher 403 presses the binding component 43 along the guide groove portion 402 as the cartridge 42 is loaded. The movable pin 404 protrudes freely on the movement trajectory of the pusher 403 of the guide groove portion 402 and restricts the operation of the pusher 403.

  The pair of long hole portions 405 respectively have a square-shaped long hole path on two predetermined surfaces of the main body portion substantially parallel to the guide groove portion 402, and support the movable pin 404 movably at both ends. The tension spring 406 urges the movable pin 404 to one end of the long hole portion 405.

  Therefore, when the cartridge 42 is not loaded, the movable pin 404 can be kept protruding from the movement path of the pusher 403 in the guide groove 402, and the pusher 403 can be prevented from dropping. In the above-described example, since the pusher 403 that descends is received by the movable pin 404, even if the pusher 403 is accidentally touched during jam processing, It is possible to stop the pusher 403 that has started to descend toward the vicinity of the binding claw portion.

  As a result, it is possible to eliminate the trouble caused by the unintentional pusher descent during the jam processing. In addition, since the movable pin 404 can be pushed up by the front end surface of the cartridge 42 and retracted along the long hole portion 405, the dropping operation of the pusher 403 can be released after the cartridge 42 is loaded. .

  In the above-described embodiment, the case where the movable pin 404 moves along the long hole portion 405 has been described. However, the present invention is not limited to this, and an effective pusher lowering is performed when the cartridge 42 is removed from the cart frame 401. The structure which retracts the plate for prevention may be sufficient. With this structure, when the cartridge 42 is loaded, the plate may be retracted by being pushed by the cartridge 42.

  The present invention relates to a binding device for bundling a plurality of sheets output from a black-and-white or color copier, a printing device, or the like, and binding the sheet bundle with a ring-shaped binding component supplied from a cartridge. It is suitable for application to a pusher lowering prevention mechanism when the cartridge is not loaded.
