Description

  The present invention relates to a post-processing apparatus, and more particularly to a post-processing apparatus that performs post-processing on a folded sheet bundle.

For example, saddle stitch folding is known in which a booklet is created by binding a bundle of sheets at approximately the center and folding the bound portion. The sheet bundle folded in this way tends to bulge in the thickness direction around the back portion, and tends to be poor in appearance. Further, when the sheet bundle swells around the back portion, when the sheet bundle is stacked in the same direction, it becomes easier to tilt as the number of stacked sheets increases, and it becomes difficult to stack a large number of sheet bundles. For this reason, for example, Patent Document 1 discloses a booklet processing apparatus that includes a molding unit that is movable in the length direction of the protruding portion and that imparts sufficient pressure to the back to flatten the curvature of the back of the folded sheet material. Proposed. On the other hand, for example, Patent Document 2 proposes a sheet cutting apparatus that cuts the edge of a booklet that has been subjected to saddle stitching processing and half-folding processing.

  In recent years, it has been desired to further improve the productivity of such post-processing applied to folded sheets.

  Accordingly, the present invention has been made to solve the above-described problems, and an object of the present invention is to improve the productivity of post-processing applied to folded sheets.

  In order to solve the above-described problem, a post-processing apparatus according to an aspect of the present invention includes a forming unit that flattens a back portion of a folded sheet bundle in a state where the folded sheet bundle is in a predetermined position, and the folded sheet. Cutting means for cutting the sheet bundle in a state where the bundle is in a predetermined position.

  According to this aspect, it is possible to perform both the process of flattening the back of the sheet bundle and the process of cutting the sheet bundle while the folded sheet bundle is in a predetermined position. For this reason, it is possible to reduce the time for positioning the sheet bundle for performing each processing, and it is possible to improve the productivity of the post-processing.

  The cutting unit may cut the sheet bundle after the back portion of the sheet bundle is flattened by the forming unit. When the process of flattening the back part of the folded sheet bundle is performed, the edge of the sheet bundle may be slightly pulled in the back direction or pushed out in the opposite direction. It may not be neatly arranged. In order to suppress such pull-in and push-out of paper, it is necessary to take measures such as holding the paper bundle with a large force, which may increase the size and cost of the apparatus. According to this aspect, even when such sheet pull-in or push-out occurs, the sheet bundle can be cut after that, and the end of the sheet bundle can be visually improved while suppressing the increase in size and cost of the apparatus. It is possible to suppress the decrease.

  A cutting nipping unit may be further provided for nipping the sheet bundle in the vicinity of the cut portion in a state where the folded sheet bundle is in a predetermined position. The cutting clamping unit may clamp the sheet bundle after the back portion of the sheet bundle is flattened by the forming unit, and the cutting unit may cut the clamped sheet bundle. According to this aspect, even when the sheet is pulled or pushed out at the end of the sheet bundle due to the process of flattening the back of the sheet bundle, the sheet bundle is sandwiched in the vicinity of the edge thereafter. Can be trimmed. For this reason, it is possible to suppress a decrease in the appearance of the end portion of the sheet bundle by performing the process of flattening the back portion of the sheet bundle.

  The cutting unit may cut the sheet bundle so that at least a part of the step of cutting the sheet bundle is parallel to at least a part of the step of flattening the back of the sheet bundle by the forming unit. According to this aspect, these steps can be performed in a shorter time than when the step of cutting the sheet bundle and the step of forming are performed separately, and post-processing productivity can be improved.

  The cutting unit may cut the sheet bundle during the process of flattening the back of the sheet bundle by the forming unit. The process of cutting a paper bundle is performed in a short time by the blade, whereas the process of flattening the back of a paper bundle can take longer than the cutting process, such as applying pressure to the back using any method. High nature. According to this aspect, since the cutting process can be performed while the molding process is being performed, the post-processing productivity can be improved.

  The forming unit may include a pressing member that is pressed against the back part of the sheet bundle, and a pressing member moving unit that moves the pressing member against the back part of the sheet bundle while moving the pressing member against the back part. The cutting means may cut the sheet bundle while the pressing member is moving. In this way, the molding process of moving the pressing member along the back portion is likely to take time compared to the cutting process. According to this aspect, since the cutting process can be performed when the pressing member is moving as described above, the productivity of post-processing can be improved.

  In the state where the folded sheet bundle is in a predetermined position, the molding clamping means for sandwiching the sheet bundle in the vicinity of the back part, and in the state where the folded sheet bundle is in the predetermined position, the sheet bundle is formed in the vicinity of the cut portion. And a cutting clamping means for clamping. The forming unit may flatten the back portion of the sheet bundle in a state where the sheet bundle is clamped by the molding clamping unit and the cutting clamping unit. According to this aspect, it is possible to perform the forming process while strongly pinching the sheet bundle as compared with the case where the sheet bundle is sandwiched only by the forming clamping means. For this reason, it is possible to suppress a decrease in the appearance of the end of the sheet bundle after the post-processing.

  In the case where the length of the sheet bundle between the flattened back portion and the end portion opposite to the back portion formed by cutting is the post-processing paper bundle length, the forming means or the cutting means is the post-processing paper It may be provided so as to be movable in the paper length direction after processing so as to change the bundle length.

  There are various requirements for the post-processing sheet bundle length. For this reason, in the case where the forming process and the cutting process are performed in a state in which the sheet bundle is in a predetermined position as in the post-processing apparatus according to this aspect, it is considered that various post-processed sheet bundle lengths are supported. There is a need. According to this aspect, since the forming unit or the cutting unit can be moved in accordance with the post-processed paper bundle length, the paper bundle is in a predetermined position corresponding to various post-processed paper bundle lengths. Thus, it is possible to carry out the molding process and the cutting process.

  You may further provide the mounting part which mounts the paper bundle in the state in which the folded paper bundle exists in a predetermined position. The placement unit may change the length in the post-processing sheet bundle length direction according to the movement of the forming unit or the cutting unit. According to this aspect, it is possible to suppress a decrease in the sheet bundle conveyance performance by moving the forming unit or the cutting unit.

  A plurality of rollers may be further provided that are arranged side by side in the length direction of the sheet bundle after processing and form a placement portion on the outer periphery of the belt by attaching the belt to the outer periphery. Any of the plurality of rollers may change the length of the stacking unit in the post-processing sheet bundle length direction by moving in the post-processing length direction according to the movement of the forming unit or the cutting unit. According to this aspect, the length of the post-processing sheet bundle length direction of the stacking unit can be changed with a simple configuration.

  According to the present invention, the productivity of post-processing applied to a folded sheet can be improved.

  Further, two rollers 134 are provided in the vicinity of the molding unit rear frame 138 at positions similar to the two rollers 134 provided in the vicinity of the molding unit front frame 136 in the conveying direction and the vertical direction. Two rollers 134 in the vicinity of the molding unit rear frame 138 are fixed to the molding unit rear frame 138 so as to be rotatable together by a shaft (not shown). The two rollers 134 arranged in the vicinity of the forming unit rear frame 138 are arranged behind the apparatus from the sheet bundle passage area.

The outer periphery of the first conveying surface F ₁ from above and the front of the apparatus of the roller 134, and the first conveying surface F ₁ from above and rear of the device of the roller 134, the roller moving belt 126 is mounted. The first conveying surface F ₁ from below and the front of the apparatus of the roller 134, and also outer periphery of the first conveying surface F ₁ from below and the rear of the device of the roller 134, another roller moving belt 126 is mounted.

  The second support member 116 of the roller unit 110 is disposed between two roller moving belts 126 arranged side by side in the vertical direction of the roller moving unit 124, and is fixed to the two roller moving belts 126 so as to move together. . At this time, the roller unit 110 is fixed to the upstream linear portion of the two linear portions of the roller moving belt 126 extending in the longitudinal direction of the apparatus. Further, the roller unit 110 is attached to the roller moving belt 126 so that the forming roller 112 faces the upstream side and the central axis of the forming roller 112 faces the vertical direction. At this time, the outer periphery of the most upstream side of the forming roller 112 is upstream of the abutting surface of the stopper 166 and downstream of the most downstream side surface of the upper surface pressing member 92. Is configured.

  The roller unit 110 is normally in a standby position in front of or behind the sheet bundle passage area. When the motor 130 is actuated, the roller unit 110 is moved in the front-rear direction of the apparatus, enters the sheet bundle passage area from outside the sheet bundle passage area, and is moved out of the sheet bundle passage area on the opposite side of the apparatus front-rear direction. At this time, the forming roller 112 moves in the longitudinal direction of the apparatus along the back of the sheet bundle while applying pressure to the back of the sheet bundle positioned by the stopper 166. Therefore, the forming roller 112 functions as a pressing member that is pressed against the back of the sheet bundle, and the roller moving unit 124 functions as a pressing member moving unit that moves the forming roller 112 along the back while pressing the forming roller 112 against the back of the sheet bundle. To do. The forming unit 125 functions as a forming unit that flattens the back portion of the sheet bundle. By this forming process, the back portion of the sheet bundle is flattened to a plane substantially perpendicular to the side surface of the sheet bundle.

A conveyance guide 140 is provided between the collating devices 12 arranged above and below. Conveying guide 140 is formed in a plate shape, its upper surface is positioned so as to be located below the parallel and the first conveying surface F ₁ and the first conveying surface F _1. A rack gear 142 is fixed to the transport guide 140. The gear portion of the gear 144 meshes with the gear portion of the rack gear 142. Further, the gear portion of the gear 144 meshes with the gear portion of the gear 144. The gear 146 is fixed to the motor shaft of the motor 148 so as to be rotatable. When the motor 148 operates, the conveyance guide 140 moves in parallel with the conveyance direction. The motor 130 is connected to the electronic control unit 100. The electronic control unit 100 performs the molding process by operating the motor 130. Therefore, the electronic control unit 100 also functions as a molding control unit that performs the molding process.

  The conveyance guide 140 is disposed on the most downstream side while the molding process by the molding unit 125 is being performed. At this time, the transport guide 140 is arranged such that the position of the upstream end in the transport direction is substantially the same as the position of the downstream end of the second support member 116 in the transport direction. This suppresses the roller unit 110 from moving downstream due to the roller moving belt 126 being bent during the molding process. Accordingly, the conveyance guide 140 functions as a roller unit locking unit that suppresses the movement of the roller unit 110 in the direction opposite to the direction in which the pressure is applied to the back of the sheet bundle by the roller unit 110.

  When the molding process by the molding unit 125 is completed, the conveyance guide 140 is moved upstream until the upstream end approaches the downstream side surface of the molding pressing unit 80. Therefore, the transport guide 140 also functions as a guide when transporting the sheet bundle subjected to the forming process and the cutting process downstream. A motor 148 is also connected to the electronic control unit 100. The electronic control unit 100 controls the movement of the conveyance guide 140 by controlling the operation of the motor 148.

  The forming unit frame including the forming unit front frame 136 and the forming unit rear frame 138 is configured to be movable in a direction parallel to the conveying direction with respect to the main body frame including the front frame 88 and the rear frame 90. A molding pressing unit 80, a stopper 166, a molding unit 125, and a conveyance guide 140 are attached to the molding unit frame. As the forming unit frame moves, these components also move, and the position of the back of the sheet bundle after the forming process changes. As a result, when the length of the sheet bundle between the flattened back portion and the cut end formed on the side opposite to the back portion is defined as the post-processing sheet bundle length, the post-processing sheet bundle length is Change.

  The electronic control unit 100 is also connected to a control panel (not shown) that can be input by the user. The control panel is configured so that the user can input the post-processing sheet bundle length. Therefore, the control panel functions as a post-processing sheet bundle length input unit. Information indicating the post-processing sheet bundle length input by the user is output to the electronic control unit 100.

  The molding unit frame is connected to a motor (not shown) via a gear. Hereinafter, this motor is referred to as a molding position moving actuator. The molding position moving actuator is connected to the electronic control unit 100. The electronic control unit 100 moves the forming unit frame in a direction parallel to the transport direction using the input information indicating the post-processing sheet bundle length. As a result, the molding pressing unit 80, the molding unit 125, the stopper 166, and the like attached to the molding unit frame are moved. Accordingly, the electronic control unit 100 functions as a control unit that controls the position of the back of the sheet bundle after flattening by controlling the operation of the forming position moving actuator, and controls the post-processing sheet bundle length.

  There are various sizes of paper bundles to be subjected to the forming process and the cutting process. Further, the length from the back portion of the sheet bundle before the forming process positioned by the stopper 166 to the back portion of the sheet bundle after the forming process varies depending on the thickness of the sheet bundle. For this reason, it is required to change the position of the back portion after the forming process depending on the thickness of the sheet bundle.

  When the movable blade 52 and the forming unit 125 perform processing on a sheet bundle at different positions, various post-processed sheet bundle lengths can be handled by controlling the stop position and stop timing of the sheet bundle. Is possible. However, when the forming process and the cutting process are performed in a state where the sheet bundle is in a predetermined position positioned by the stopper 166 as in the forming / cutting unit 50 according to the present embodiment, the process is performed according to the stop position and stop timing of the sheet bundle. It is difficult to cope with the rear sheet bundle length.

  The forming and cutting unit 50 according to the present embodiment can move the forming unit 125 in the post-processing sheet bundle length direction in accordance with the post-processing sheet bundle length. Therefore, even when the forming process and the cutting process are performed on the sheet bundle at the same predetermined position, it is possible to cope with various post-processed sheet bundle lengths.

The second roller 66 to the fifth roller 72 are attached to the molding unit frame. Accordingly, the lengths of the first transport surface F ₁ and the second transport surface F ₂ formed on the transport belt 62 change in the transport direction, that is, the post-processing sheet bundle length direction, according to the movement of the forming unit 125. . For example, if the molding unit 125 is moved toward the movable blade 52, the length of the first conveying direction of the conveying surface F ₁ is shortened. If molding unit 125 conversely moves in a direction away from the movable blade 52, the length of the first conveying direction of the conveying surface F ₁ becomes longer.

And configuring short fixed in the length direction of the first conveying surface F ₁ of the previously processed sheet Tabacho direction in consideration of the movement of the molding unit 125, a first conveying surface when molding unit 125 is moved to the downstream side F ₁ range of the sheet bundle is not placed is increased over, there is a possibility that the sheet bundle is bent. In forming the cutting unit 50 according to the embodiment contrast, by the length of the first conveying direction of the conveying surface F ₁ is changed according to the movement of the molding unit 125, to be stably placed on sheet bundle It becomes possible.

  A plurality of wire rollers 84 are provided on each of the shafts to which any one of the first roller 64, the second roller 66, the sixth roller 74, the seventh roller 76, and the eighth roller 78 is fixed. Three wire rollers 84 are provided between two rollers fixed to each shaft, two are provided in front of the rollers on the front side of the apparatus, and two are provided on the rear side of the rollers on the rear side of the apparatus.

The wire 86 is drawn around the outer periphery of these wire rollers 84, and both ends are connected to the lower surface pressing member 94 and the conveyance guide 140, respectively. Wire 86 supports the portion of the sheet bundle is not placed by the first conveying surface F ₁ and the second conveying surface F _2. A spring 154 is interposed in the middle of the wire 86. The spring 154 expands and contracts as the transport guide 140 moves in a direction parallel to the transport direction. Thereby, the looseness of the wire 86 due to the movement of the conveyance guide 140 is suppressed.

  FIG. 5 is a flowchart showing an operation procedure of the forming and cutting apparatus 16 according to the first embodiment. A conveyance sensor that detects conveyance of the sheet bundle is provided in the conveyance path of the sheet bundle to the forming and cutting unit 50. The processing in this flowchart starts when the electronic control unit 100 determines that the sheet bundle that has undergone saddle stitching and folding processing has been transported to the forming trimming unit 50 by the transport sensor.

  When the sheet bundle is conveyed to the forming and cutting unit 50, the electronic control unit 100 conveys the sheet bundle to the inside of the forming and cutting unit 50 by the conveying unit 57 (S11). At this time, the sheet bundle is conveyed so that the back portion is located on the downstream side. The electronic control unit 100 operates the transport unit 57 until the back of the sheet bundle is abutted against the stopper 166. As a result, the back of the sheet bundle is positioned (S12). When the back of the sheet bundle is abutted against the stopper 166, the electronic control unit 100 stops the operation of the conveyance unit 57 and stops conveyance of the sheet bundle.

When the sheet bundle is positioned at a predetermined position by the stopper 166, the electronic control unit 100 operates the molding pressing unit 80 to sandwich both side surfaces of the sheet bundle near the back (S13). When the sheet bundle is nipped by the forming pressing unit 80, the electronic control unit 100, the power has been supplied to the solenoid 162 is stopped, thereby leaving the lower stopper 166 from the first conveying surface F ₁ (S14).

  When the stopper 166 is withdrawn, the electronic control unit 100 performs a molding process by the molding unit 125 (S15). Specifically, the roller unit 110 is moved along the back part of the sheet bundle while pressing the back part of the sheet bundle by the roller unit 110.

  When the forming process is completed, the electronic control unit 100 operates the cutting press actuator in the cutting press unit 55 to move the fore edge pressing member 54 downward, thereby holding the vicinity of the part to be cut (S16). As a result, even when the sheet is pulled or pushed out at the end of the sheet bundle due to the forming process, the sheet bundle can be nipped and cut in the vicinity of the cut portion along the edge. For this reason, it is possible to suppress a decrease in the appearance of the end portion of the sheet bundle due to the forming process.

  When the sheet bundle is clamped in the vicinity of the part to be cut by the cutting press unit 55, the electronic control unit 100 performs a cutting process by the movable blade 52 (S17). Specifically, the electronic control unit 100 operates the cutting actuator, moves the movable blade 52 downward, and cuts the edge protruding upstream from the cutting press unit 55. When the sheet bundle is cut, the electronic control unit 100 operates the cutting actuator to pull the movable blade 52 back to the upper reference position.

  As described above, the forming and cutting unit 50 according to this embodiment performs the forming process of flattening the back portion of the sheet bundle in a state where the sheet bundle subjected to the saddle stitching and folding process is in a predetermined position positioned by the stopper 166. And a cutting process for cutting the sheet bundle. As a result, the time required for positioning the sheet bundle can be reduced, and post-processing productivity can be improved.

  Further, as described above, in the forming and cutting unit 50 according to the present embodiment, the cutting pressing unit 55 holds the sheet bundle near the cut portion of the sheet bundle after the forming process by the forming unit 125 is completed. The movable blade 52 cuts the sheet bundle after the molding process by the molding unit 125 is completed.

  When the forming process for flattening the back part of the folded sheet bundle is performed, if the force for holding the sheet bundle by the forming pressing unit 80 is weak, the sheet is slightly pulled in the back direction at the end of the sheet bundle, There is a possibility of being pushed out in the opposite direction. For this reason, if the cutting process is performed before the forming process, the ends of the sheet bundle may not be neatly aligned.

  In order to suppress such pull-in and push-out of the paper, it is necessary to take measures such as holding the paper bundle with a large force. However, such a measure may lead to an increase in size and cost of the apparatus. By performing the cutting process after performing the forming process in this way, even when the sheet is pulled or pushed out by the forming process, the sheet bundle can be cut after that. Accordingly, it is possible to suppress a decrease in the appearance of the end portion of the sheet bundle while suppressing an increase in size and cost of the apparatus.

  When the cutting process is finished, the electronic control unit 100 operates the molding pressing actuator to release the holding of the sheet bundle by the molding pressing unit 80. Further, the electronic control unit 100 operates the cutting actuator to release the holding of the sheet bundle by the cutting pressing unit 55 (S18).

When the holding by the molding press unit 80 and the cutting press unit 55 is released, the electronic control unit 100 operates the motor 148 to move the transport guide 140 to the upstream side (S19). When the movement of the conveyance guide 140 to the upstream side is completed, the electronic control unit 100 operates the conveyance unit 57 to convey the sheet bundle and discharge it from the discharge port to the stacker 18 (S20). When the sheet bundle is conveyed from the forming cutting unit 50, the electronic control unit 100, the moved again to the downstream side working Well conveying guide 140 of the motor 148 (S21), the stopper 166 above the first conveying surface _{F 1} Advance (S22). The forming and cutting unit 50 stands by in this state until the forming process and the next sheet bundle to be subjected to the cutting process are conveyed to the forming and cutting unit 50.

(Second Embodiment)
FIG. 6 is a flowchart showing an operation procedure of the forming and cutting apparatus 16 according to the second embodiment. In addition, the shaping | molding cutting unit 50 which concerns on 2nd Embodiment has the structure similar to the shaping | molding cutting unit 50 which concerns on 1st Embodiment. Similarly to the flowchart shown in FIG. 5, the processing in this flowchart also starts when the electronic control unit 100 determines that the sheet bundle that has undergone saddle stitching and folding processing has been transported to the forming trimming unit 50 by the transport sensor.

  The processing in S31 and S32 is the same as S11 and S12 shown in FIG. When the sheet bundle is positioned at a predetermined position by the stopper 166, the electronic control unit 100 operates the cutting actuator and the cutting press actuator to hold the sheet bundle in the vicinity of the back by the forming press unit 80. The sheet bundle is clamped by the pressing unit 55 in the vicinity of the part to be cut (S33).

Then, the electronic control unit 100, stops the supply of power to the solenoid 162 to exit the stopper 166 below the first conveying surface _{F 1} (S34). When the stopper 166 is retracted, the electronic control unit 100 performs the molding process by the molding unit 125 and the cutting process by the movable blade 52 (S35). At this time, the electronic control unit 100 performs the cutting process by the movable blade 52 during the molding process in which the molding process by the molding unit 125 is performed.

  Specifically, the electronic control unit 100 moves the movable blade 52 downward to cut the sheet bundle while the roller moving unit 124 moves the roller unit 110 along the back of the sheet bundle. In the molding process in the present embodiment, the back unit is flattened by moving the roller unit 110 along the back while applying pressure to the back of the sheet bundle by the roller unit 110. For this reason, the molding process takes longer than the cutting process of moving the movable blade 52 downward by a short distance. By performing the cutting process when the forming process is performed in this way, the time for performing the cutting process can be suppressed, and the productivity of the post-processing can be improved.

  Further, the electronic control unit 100 performs the forming process by the forming unit 125 and the cutting process by the movable blade 52 in a state where the sheet bundle is sandwiched between the forming pressing unit 80 and the cutting pressing unit 55. As a result, the sheet bundle can be held with a stronger force than in the case where the sheet bundle is held only by the forming pressing unit 80 or only by the cutting pressing unit 55. For this reason, it is possible to suppress the drawing and extrusion of the sheet at the end of the sheet bundle due to the forming process or the cutting process, and it is possible to suppress the deterioration of the appearance of the end of the sheet bundle after the forming process or the cutting process is performed. be able to.

  When the molding process and the cutting process are finished, the electronic control unit 100 operates the molding pressing actuator and the cutting actuator to release the holding of the sheet bundle by the molding pressing unit 80 and the cutting pressing unit 55 (S36). Note that the processing in S37 to S40 is the same as the processing in S19 to S22 in FIG.
