  As described above, in a device in which the cutting waste cut by the cutting means is carried out of the device by a conveyor or the like and stored in a waste box or a plastic bag prepared by an operator, the device is large and installation space increases. In addition, waste boxes, plastic bags, etc. are exposed to the outside of the apparatus, which is not preferable in terms of the appearance of the apparatus, and there has been a problem in apparatus design. On the other hand, there is also a device that has a box for storing cutting waste inside the cutting device. Either an operator takes out the waste from the box inside the device or a plastic bag prepared by the operator is taken out. Because of its configuration, it is forced to do very dangerous work. In particular, if the internal cutting waste is carelessly removed while the device is operating, there is a risk of injury to the fingers with the operating cutting blade. Similarly, the cutting blade protrudes into the path even when the device is not operating. In this state, there is a risk of injury when removing the debris. This is because the waste box for storing the cutting waste is installed in the path where the cutting blade is arranged in the apparatus, and there is a possibility that the cutting blade may be touched when removing the waste.

  Therefore, a device configuration in which the waste box is pulled out from the inside of the device is also conceivable. However, in this case, the space for fingers to enter the inside of the device is opened when the waste box is pulled out to the outside of the device. For example, it is equally dangerous to try to remove the swarf that is scattered in the device, and it is very dangerous if done carelessly while the device is in operation. In view of the above problems, the main object of the present invention is to provide a sheet bundle cutting device that can safely and easily remove the cutting waste when sequentially cutting sheet bundles.

And the said waste storage box is provided with the waste storage tray which accommodates a cutting waste, and the said waste storage tray is comprised so that it can detach | leave from the said housing in the said scrap extraction position. Further, the waste storage box includes a base frame and a waste storage tray that is detachably attached to the base frame, and the base frame is movably supported by a guide member provided in the housing. It is characterized by that.

Further, the cutting means is movable between the cutting position and a home position as the retracted position, and the home position is configured such that the cutting means is isolated from the outside, and the cutting means is the home position. Sensor means for detecting whether or not it is located at a position, and the control means releases the lock means when the cutting means is located at the home position by a signal from the sensor means. It is said. The waste storage box is provided with an open / close switch operated when moving from the waste storage position to the waste removal position, and the control means is configured such that when the open / close switch is operated, the cutting means is in the home position. In this case, the lock means is released. Further, a flapper member that guides the cutting waste from the cutting means to the waste storage box is disposed in the transport path so as to be movable between an operating position in the transport path and a position outside the path. The position outside the path is set to a position that isolates the cutting means from the outside, and the flapper member is provided to the shift means so that it is located at the position outside the path when the waste container box is located at the waste removal position. It is characterized by being connected.

In the present invention, cutting waste when cutting a bundle-like sheet fed into a path by a cutting means is stored in a waste storage box disposed in a housing forming an apparatus exterior, and the waste storage box is stored in waste. movably configured between a position the housing outside the debris removal position, by which to be able to leave the waste receiver tray detachably attached to the waste receiver box this debris removal position outside the apparatus, the operator must In each case, the waste storage box can be pulled out to the waste removal position, and the waste storage tray can be removed from the waste storage box for processing. Therefore, since only the waste storage tray can be removed and processed, the processing of cutting waste is simplified.

  In addition, when the cutting means such as a cutting blade is located at the retracted position outside the path isolated from the outside, the waste container tray is configured to be movable to the waste removal position, so that the operator can touch the cutting means during the waste removal operation. It has remarkable effects such as ensuring safety without being injured.

  The present invention will be described in detail below based on the preferred embodiments shown in the drawings. FIG. 1 is an explanatory diagram showing an overall configuration of a sheet bundle cutting apparatus A employing the present invention, and FIG. 2 is a flowchart showing an operation flow thereof.

  In FIG. 1, in a housing 10 formed of an outer casing, a conveyance path 11 having a receiving port 11a for a bundled sheet S and a discharge port 11b is constituted by an appropriate paper guide. In the conveyance path 11, a carry-in roller 12, a rotary table unit 20, and a cutting unit 30 are sequentially arranged on the downstream side in this order. A paper discharge roller 40 is disposed at the exit end of the transport path 11, and a storage stacker 45 and a waste storage box 50 are disposed below the discharge roller 40. In the figure, the conveyance path 11 is configured in a substantially vertical direction, and a sheet bundle from the paper discharge roller 40 is stored in an inverted posture in a storage stacker 45, and cutting waste generated by the cutting means 30 disposed in the conveyance path 11 is It arrange | positions so that it may be fall-accommodated by the waste storage box 50 located below a path | route.

  In the receiving port 11a of the cutting apparatus A arranged in this way, a bundled sheet S bound in a bookbinding state is bound, for example, the front and back of a saddle stitched sheet bundle is wrapped with a cover sheet and the back is bound with adhesive glue ( It is carried in a case binding (bookbinding) state, or is carried in a state where the back of the sheet bundle is stapled. A carry-in roller 12 is provided downstream of the receiving port 11a, and a pair of rollers are arranged so as to approach and separate from each other according to the thickness of the sheet bundle, and are connected to the conveyance motor M1. The carry-in roller 12 is connected to a sheet bundle thickness detecting unit 13 for detecting the thickness of the sheet bundle, and detects the thickness by detecting the distance between the pair of rollers (the amount of movement of the rollers). Further, a sheet sensor S1 that detects the leading edge of the bundled sheet S is disposed at the receiving port 11a, and detects the carry-in of the sheet bundle. The detection of the thickness of the sheet bundle and the leading edge of the sheet bundle is used for subsequent control, for example, setting of a standby position of the cutting unit 30 described later. 10a is an opening / closing cover disposed at the receiving port 11a.

  A rotary table unit 20 that deflects the direction and orientation of the bundled sheet S is disposed in the transport path 11 on the downstream side of the carry-in roller 12. The turntable unit 20 includes a turntable 21 and a gripper 22, and is configured to be able to move downward in the rotation and conveyance path direction while holding the bundled sheet S therebetween. For this reason, the gripper 22 is supported by the unit frame 23 so as to be movable in the direction perpendicular to the conveyance path, and is connected to the gripper motor MG. Further, the rotary table 21 is supported by the unit frame 23 so as to be able to turn and is connected to a turning motor MT. The unit frame 23 is supported by a guide rail (not shown), is movably supported in the vertical direction in FIG. 1, and is connected to the lifting motor MS.

  Accordingly, the bundled sheet S from the carry-in roller 12 is sent to the rotary table unit 20 and is sandwiched between the rotary table 21 and the gripper 22, and the direction of the bundled sheet S is deflected by the rotation of the rotary table 21. That is, it becomes possible to make the top part, the ground part, and the fore edge part of the bundled sheet S face the cutting means 30 on the downstream side. At the same time, the rotary table unit 20 is moved to the downstream cutting position X along the transport path 11 by the elevating motor MS, and the cutting width is set by the feed amount.

  A cutting means 30 is disposed at a cutting position X on the downstream side of the rotary table unit 20. The illustrated cutting means 30 includes a flat blade-shaped cutter blade 31, a press means 32, and a die member 33, and the die member 33, the press means 32, and the cutter blade 31 are disposed to face each other with the conveyance path 11 interposed therebetween. The press means 32 includes a press member 32 a and a press motor MP that presses and moves the press member 32 a toward the die member 33. The press member 32 a sandwiches the bundled sheet S between the die member 33 by driving the press motor MP. Press. As a result, the bundled sheet S is held at the cutting position X. Further, the flat blade-shaped cutter blade 31 is supported by the apparatus frame so as to be movable in the illustrated horizontal direction, and is connected to the cutter motor MC.

  Accordingly, the bundled sheet S sent from the rotary table 21 is held by the pressing means 32, and the edge is cut by the cutting means 30 in this state. After cutting one end surface of the sheet bundle, for example, the top portion, the posture is deflected by the rotary table 21, and then, for example, the ground portion is cut, and then the fore edge portion is cut. After the predetermined edge portion is cut in this way, when the nipping of the rotary table 21 is released, the bundled sheet S falls onto the downstream discharge roller 40. A storage stacker 45 and a waste storage box 50 are disposed downstream of the paper discharge roller 40. The paper discharge roller 40 is composed of a pair of rollers and is connected to a drive motor (not shown). A storage stacker 45 and a waste storage box 50 are provided downstream of the paper discharge roller 40 at a position continuous with the transport path 11.

  A flapper member 41 is provided downstream of the paper discharge roller 40 and is disposed so as to guide the cutting waste falling from the cutting position X to the waste storage box 50. The flapper member 41 is supported at its base end so as to be swingable, and is connected to shift means such as a shift motor MF. Details thereof will be described later.

  Therefore, the operation of the above-described apparatus will be described with reference to FIG. 2. The bundled sheet S is subjected to, for example, bookbinding binding processing as a pre-process or binding processing from a bookbinding binding apparatus connected to the upstream side of the receiving port 11a. The sheet bundle is set in the receiving port 11a (St100). Although not shown in FIG. 1, gate means for abutting and restricting the front end of the sheet bundle such as a gate stopper and a registration roller is disposed downstream of the carry-in roller 12. The sheet sensor S1 detects the bundled sheet S set in this way, and drives the conveyance motor M1 of the carry-in roller 12 to nip the bundled sheet S (St101). At this time, the sheet bundle thickness detection means 13 detects the bundle thickness. The bundle thickness information is sent to, for example, the control CPU of the apparatus, and the subsequent operation is controlled based on this information.

  Next, the carry-in roller 12 is activated and rotated by the conveyance motor M <b> 1, and sends the bundled sheet S to the rotary table 21 on the downstream side. In the rotary table 21, the gripper 22 holds the bundled sheet S with the gripper motor MG (St102). Therefore, the rotary table 21 is rotated by a predetermined angle, for example, 90 degrees by the turning motor MT to deflect the posture of the sheet bundle (St103). After the sheet bundle is thus changed to a preset posture, the rotary table unit 20 is lowered along the transport path 11 by the lifting motor MS. At this time, the leading edge detection sensor S2 is disposed at the cutting position X of the conveyance path 11 to detect the leading edge of the bundled sheet S (St104). When a predetermined amount is conveyed from this detection signal, the preset cut line of the bundled sheet S coincides with the cutting position X (St105). Therefore, the press motor MP of the press means 32 is activated, and the press member 32a holds the bundled sheet S with high pressure on the die member 33 (St106).

  Next, the cutter motor MC is activated by a signal (press end signal) from the press end sensor disposed on the press member 32a, and the cutter blade 31 moves from the standby position WP shown in FIG. 3 to the left side in FIG. In this state, the lower edge of the sheet bundle is cut (St107). The cutter blade 31 moves from the home position indicated by HP in FIG. 3 to the standby position WP based on the bundle thickness information from the sheet bundle thickness detecting means 13 described above and stands by. The standby position WP is set at a distance according to the bundle thickness at a position close to the home position HP when the sheet bundle is thick, and at a far position when the sheet bundle is thin. This is because the cutting operation is performed quickly. Therefore, the cutter blade 31 is provided with a sensor flag 31a. Position sensors Sc1 and Sc2 for detecting the sensor flag 31a are arranged as shown in FIG. 4, and the position sensor Sc1 sets the home position HP to the position of the position sensor Sc1. The sensor Sc2 detects the cutting position CP. Accordingly, the position sensor Sc1 constitutes sensor means for detecting whether or not the cutting means 30 is located at the home position.

  Simultaneously with the cutting of the bundled sheet S, the cut waste is stored in the waste storage box 50 (St108). During the sheet bundle cutting operation, the aforementioned flapper member 41 is moved from the solid line position in FIG. 3 to the solid line position in FIG. 4, and the shift motor MF (shift is performed so as to guide the falling cutting waste to the waste storage box 50 side. Means).

  Next, after the cutting operation is finished, the press motor MP of the press member 32a rotates in the reverse direction to release the pressing of the sheet bundle (St109). Before and after this, the cutter blade 31 returns to the home position HP by the reverse rotation of the cutter motor MC (St110). Accordingly, it is determined whether or not the above-described cutting of the lower edge of the sheet bundle has been set in advance, for example, in three directions (top portion, ground portion, fore edge portion) (St111), and when all scheduled cutting ends, the storage stacker is finished. It is carried out to 45 (St112). If the scheduled cutting is not completed, the turntable 21 backs the transport path 11 by a predetermined amount (St113) to secure an area for rotating the bundled sheet S. Thereafter, the bundled sheet S is rotated (St114), and the process returns to step 104 described above. For carrying out the bundled sheet S to the storage stacker 45, the flapper member 41 is moved to the position indicated by the chain line in FIG. 3 by the shift motor MF to open the conveyance path 11, and then the discharge roller 40 is driven to rotate. Then, the bundled sheets S fed out by the paper discharge roller 40 are carried into the storage stacker 45 and sequentially stacked in an inverted posture as shown in FIG.

Therefore, the present invention employs the following configuration in the above-described apparatus.
First, the housing 10 described above forms an apparatus outer casing with an outer case or the like, and the illustrated one is configured in a substantially box shape. Each mechanism described above is built in the housing 10. The housing 10 is equipped with a storage stacker 45 for the bundled sheets S and a waste storage box 50 so that they can be pulled out to the front side of the apparatus (front side in FIG. 1). First, the storage stacker 45 has a box-shaped storage tray 47 mounted on a guide rail 46 provided on the housing 10 side so that it can be pulled out by a guide roller 48.

  On the other hand, the waste storage box 50 includes a base frame 51 and a waste storage tray 54, and has a shape shown in FIGS. As shown in FIG. 8A, the base frame 51 is configured by a frame frame having a guide rail 53b integrated with the front door 52, and a rail 53b is provided on a guide member provided on the apparatus housing 10 side, for example, a guide roller 53a. It is fitted and slidably supported. A waste storage tray 54 is detachably supported on the base frame 51. As shown in FIG. 5B, the waste storage tray 54 is configured by a box-shaped tray member that stores cutting waste, and a guide wall 54a and a handle 54b that guide the cutting waste are integrally formed. In addition, Sf1 shown to Fig.5 (a) is a full detection sensor, and Sf2 is a near full detection sensor. A waste storage box 50 is configured by detachably supporting the waste storage tray 54 on the base frame 51. The front door 52 is provided with an open / close switch 52a. When the front door 52 is pulled out of the housing, the open / close switch 52a is operated.

  The waste storage box 50 configured as described above is slidably supported by the housing 10 between a waste storage position indicated by a chain line in FIG. 7 and a waste removal position indicated by a solid line. At the waste storage position, the sensor flag 55 formed on the waste storage tray 54 is detected by a position detection sensor Se1 provided on the housing 10 side. Therefore, the position detection sensor Se1 detects that the waste storage tray 54 is set on the base frame 51 and that the base frame 51 exists at the waste storage position.

  Therefore, locking means 56 for locking the base frame 51 at the waste storage position is provided on the housing 10 side. FIG. 8 illustrates a case where the locking means is constituted by a lock pin 57a and an operating solenoid 58 connected to the lock pin 57a via a connecting lever 57b. A biasing spring (not shown) is applied to the lock pin 57a so as to be fitted into a locking groove 51a formed in the base frame 51 of the waste container box 50. Accordingly, when power is supplied by the control means 59 and the operating solenoid 58 is electromagnetically attracted, the lock pin 57a changes from the locked state in FIG. 8B to the unlocked state in FIG. In the operating state, the lock pin 57a engages with the locking groove 51a to hold the waste container box 50 in the housing 10 and prohibit it from being pulled out of the housing.

  Next, the following consideration is given to the cutting means 30 described above. The cutter blade 31 constituting the cutting means 30 is configured to reciprocate between the home position HP and the cutting position CP as described above. However, when the apparatus is not operated, the cutter blade 31 has a cutting edge. The retracted position is set to the retracted position from the transport path 11. That is, as shown in FIG. 6A, the cutter blade 31 is configured to be isolated from the outside of the apparatus when it is located at the home position HP (retracted position). In addition, isolation | separation from the outside means isolating so that a user's finger | toe etc. cannot enter from the housing exterior which forms an apparatus exterior here. This is because when the storage stacker 45 and the waste storage box 50 are pulled out to the take-out position outside the housing, a space for the user's fingers to enter the apparatus through the opening of the outer case is formed.

  Accordingly, in the illustrated example, the home position HP of the cutter blade 31 is set to the retracted position retracted from the conveyance path 11 and at the same time, a partition wall 60 is further provided inside the housing 10 to take out the waste storage box 50. The user's fingers are guarded against touching the cutter blade 31 when the door is opened to the position. Further, a shutter piece 41a is formed at the tip of the flapper member 41, and the flapper member 41 is set to the home position in FIG. 3 by the control of the shift motor MF. When the cutting waste is guided to the waste storage box 50, the movement is controlled to the solid line position in FIG. 4, and when the sheet bundle is carried out to the storage stacker 45, the movement is controlled to the broken line position in FIG. Accordingly, the flapper member 41 prevents the user's fingers from entering the transport path 11 when the apparatus is not operating. In the present invention, in order to isolate the cutting means 30 from the outside of the apparatus, the configuration of the partition wall 60, the shutter piece 41a of the flapper member 41, etc. is not necessarily provided, and appropriate safety measures are taken depending on the apparatus configuration. Just give it.

  Next, the operation of the above configuration will be described. FIG. 9 is a block diagram showing the control of the locking means 56. First, the apparatus performs the operation described with reference to FIG. 2 in a normal state. In the course of this operation, the waste storage box 50 is locked by engaging the locking groove 51a of the base frame 51 with the operating solenoid 58 inoperative. The cutter blade 31 of the cutting means 30 repeats the above operation among the home position HP, the standby position WP, and the cutting position CP, and is positioned at the home position HP when the apparatus is not operating. Similarly, the flapper member 41 is also moved between the solid line position in FIG. 4 for guiding cutting waste from the home position at the solid line position in FIG. 3 and the broken line position in FIG. 3 for carrying out the sheet bundle.

  Therefore, when the user operates the open / close switch 52a of the front door 52 with a full detection signal from the detection sensors Sf1 and Sf2 of the waste storage tray 54 (St01), the control means 59 uses the signal from the open / close switch 52a to cut the cutter blade 31. Is determined to be at the home position HP (St02). This determination is made based on the signal from the position sensor Sc1 described above. When the sensor is "ON", the control means 59 supplies power to the operating solenoid 58 to lock the lock pin 57a in the state shown in FIG. Release (St03). Therefore, the user can pull out the front door 52 in the direction of the arrow in FIG. On the other hand, when the sensor is “OFF”, the lock pin 57a is kept in the engagement groove 51a and the pull-out operation of the front door 52 is prohibited (St04).

  After the lock pin 57a is unlocked, the user pulls out the waste storage box 50 to the take-out position, separates the waste storage tray 54 from the base frame 51, and performs waste disposal. After the waste disposal, the waste storage tray 54 is mounted on the base frame 51 and set at the storage position. When this setting is completed, the position detection sensor Se1 confirms that the waste storage tray 54 is located at the initial storage position (St05), and issues a signal for restarting the apparatus. Then, the energization to the operating solenoid 58 is turned off, and the lock pin 57a is returned to the state shown in FIG.

  In the course of such an operation, the cutter blade 31 is positioned at the home position HP during the scrap processing operation in which the scrap storage box 50 is pulled out to the take-out position, and the cutting edge of the cutter blade 31 as described above at this position. Is isolated so as not to allow the user's fingers to enter the position retracted from the transport path 11 to ensure its safety. In the present invention, the waste container tray 54 is a box-shaped tray, but it is needless to say that it may be a bag-shaped tray.
