Description

  The present invention relates to a document processing apparatus.

  In recent years, with the progress of OA, business-related paper waste has increased rapidly, and its disposal has become a problem. Among them, in order to prevent leakage of the information, it is usual to process the document by cutting it into a strip with a shredder and then incinerating it or receiving it by a processing company.

By the way, for the purpose of protecting the global environment, there is an active movement to recycle used paper. However, the conventional paper processing method using a shredder has a problem in that a high-quality pulp raw material cannot be obtained even if the paper fiber is finely divided because the paper fibers are finely divided.

Then, it travels so that it may return through the upper part. The plurality of thin belt-like endless belts 47 are arranged at intervals so that the punching holes 43 of the holding plate 42 are not blocked by the endless belts 47. Air is allowed to pass through the punching hole 43 in the space between the two.

  Although not shown in detail, the holding device frame F is attached to the device housing 10 so as to be movable up and down. When the document processing device 1 is not in operation, the single wafer conveyed from the conveyance device 20 is used. A position where the paper P can be conveyed along the lower surface of the holding plate 42, in other words, a position where the height of the lower surface of the holding plate 42 is aligned with the height of the lower end of the driving roller 23 (hereinafter referred to as “feeding position”). ”).

  A frame upper limit switch 48 is provided inside the apparatus housing 10 and above the holding apparatus unit 41 in the feeding position. The frame upper limit switch 48 includes a transmissive photoelectric sensor, and detects that the holding device unit 41 has been raised to a predetermined position and stops the rise. Therefore, the arrangement height of the frame upper limit switch 48 may be a position slightly lowered from the lower ends of various equipment such as the supply table 11 and the delivery roller 15 existing above the holding device unit 41.

  Below the holding device unit 41, a stock table 50 and an elevating device 51 for raising and lowering the stock table are provided.

One of the pair of chains 54, 54 is a drive chain 54A, and a motor 55 is connected to a sprocket 53A around which the drive chain 54A is bridged. Then, the drive of the motor 55 is transmitted to the drive chain 54A, so that the stock table 50 is moved up and down. When the document processing apparatus 1 is not in operation, the stock table 50 stands by at a standby position spaced below the lower surface of the holding plate 42 in the holding device unit 41 at the feeding position.

  Inside the apparatus housing 10, a side sensor 56 is provided at a position slightly above the upper surface of the stock table 50 in the standby position. The side sensor 56 is a reflective photoelectric sensor, and detects reflected light from the side of a bundle of sheets P (sheet group P ′) that are bonded to each other and stocked on the stock table 50. This is to know that the sheet group P ′ has become a certain amount. Therefore, the arrangement height of the side sensor 56 only needs to be higher than the upper surface of the stock table 50 by the height when the sheet group P ′ reaches a predetermined amount.

  A drive system such as a motor of the transport device 20 and the lifting device 51, the paper detection sensor 14, the frame upper limit switch 48, the side sensor 56, and the air supply / exhaust device 44 are not shown provided inside the device housing 10. Connected to and controlled by the controller.

2. Processing of Sheet Paper by the Apparatus Next, a procedure for processing the sheet P using the document processing apparatus 1 described above will be described with reference to flowcharts (FIGS. 3 and 4) and FIGS. To do.

1) Single-sheet feeding operation Before the document processing apparatus 1 is operated, one protective sheet having the same size as the sheet P to be processed is placed on the stock table 50. Then, a bundle of sheets P to be processed is placed on the supply table 11, and a start switch on the operation panel is pressed.

  When the start switch is turned on, the feeding roller 15, the drive roller 23 of the transport device 20, the transport belt unit 45, and the air supply / exhaust device 44 are operated by a command from the controller, and a single sheet feeding operation is performed (step) S2).

  First, the lowermost one of the bundles of sheets P placed on the supply table 11 is separated from the other sheets P by the feed roller 15, passes through the slits 13, and the drive roller unit in the apparatus housing 10. 21 is fed. The fed sheet P is sandwiched between the driving roller 23 and the driven roller 26, and the traveling direction is reversed in a U shape along the arc of the surface of the driving roller 23 according to the rotational driving of the driving roller 23. (See FIG. 6). Further, as described above, the glue application roller 26A rotates in synchronization with the rotation of the drive roller 23. When the sheet P reaches the glue application roller 26A, the glue is applied to the lower surface of the sheet P. 31 is applied (see FIG. 7).

  The coated sheet P is discharged from the transport device 20 and sent to the holding device unit 41 (see FIG. 8). In the holding device unit 41, the endless belt 47 circulates and the conveying belt portion 45 is operated, and the intake fan of the air supply / exhaust device 44 is operated. Air is sucked from the lower side to the upper side. Thus, the sheet P is conveyed by the endless belt 47 while being adsorbed to the lower surface of the holding plate 42 with the surface on which the adhesive 31 is applied facing downward.

  When it is detected that the sheet P has been transported to a position almost directly above the stock table 50 in the standby position, the circulation of the endless belt 47 is stopped by an instruction from the controller (FIGS. 9 and 10). reference).

2) Lamination process When the sheet P has advanced to a position just above the standby position of the stock table 50, a lamination process (step S3) is performed. First, the lifting device 51 is actuated by an instruction from the controller, and the stock table 50 is raised (step S31). When the stock table 50 reaches the holding plate 42, the stock table 50 continues to rise while pushing up the holding plate 42, and pushes up the entire holding device unit 41 to which the holding plate 42 is fixed to a position (stacking position) above the feeding position. (See FIG. 11). As a result, the sheet P adsorbed on the holding plate 42 is overlapped with the protective paper placed on the stock table 50 and bonded via the glue 31. At this time, the sheet P on the stock table 50 and the protective paper are press-bonded by the weight of the holding device unit 41.

  When the frame upper limit switch 48 detects that the holding device unit 41 has been raised to a predetermined position, the information is sent to the controller (step S32). More specifically, when the holding device unit 41 is pushed up to a certain position, a light shielding plate (not shown) provided on the holding device frame F includes an optical axis of a transmissive photoelectric sensor in which the frame upper limit switch 48 is provided. By entering the inside and blocking the light, it is detected that the holding device unit 41 has reached a predetermined position. Then, the intake fan of the air supply / exhaust device 44 is stopped by the instruction from the controller, and the exhaust fan is activated (step S33). At the same time, the driving direction of the chain 54 in the lifting device 51 is reversed. As a result, the stock table 50 is lowered, and the sheet P is released from the suction to the holding plate 42 and lowered together with the stock table 50 (see step S34, FIG. 12).

  The laminated body of the sheet P and the protective paper placed on the stock table 50 once enters the optical axis of the light projected from the side sensor 56 when the stock table 50 is lowered, and further the stock table 50. Falls off the optical axis again. Thus, the side sensor 56 detects that the stock table 50 has been lowered to the standby position. When this information is sent to the controller, the operations of the lifting device 51 and the air supply / exhaust device 44 are stopped by an instruction from the controller.

3) Processing of the second and subsequent sheets and discharging of the processed sheet group P ′ As described above, when the processing of the first sheet P is completed, the paper detection sensor 14 It is detected whether or not the sheet P to be processed exists on the supply table 11 (step S4). When the presence of the sheet P on the supply table 11 is detected, the information is sent from the paper detection sensor 14 to the controller, and the one-sheet feeding operation and the stacking process described above are repeated according to instructions from the controller. In the stacking process, when the second and subsequent sheets P are processed, a sheet group P ′, which is a bundle of sheets P that have been previously bonded, is placed on the stock table 50. Thus, the newly supplied sheet P is stacked on the sheet group P ′. By repeating such an operation, the plurality of sheets P are sequentially bonded and stacked so as not to be separated from each other.

  Now, when the processed sheet group P ′ reaches a certain amount, even if the stock table 50 is lowered to the lowest standby position, the height of the sheet group P ′ above it is the side sensor 56. The presence of the sheet group P ′ is detected by the side sensor 56 without falling below the installation position (step S35). In such a state, the information is sent to the controller, and a display for prompting discharge of the sheet group P ′ is made on the operation panel according to an instruction from the controller. An extraction door is provided on the side surface of the apparatus housing 10, and the operator can open the door and take out the sheet group P ′ from the stock table 50.

4) Summary As described above, according to the document processing apparatus 1 of the present embodiment, a plurality of sheets P are bonded to each other to be difficult to separate, so that each sheet P is described. Confidential information is hidden. Thereby, leakage of information can be prevented. Further, since the paper is not cut finely as in the case of using a shredder, the sheet P can be recycled as a raw material for high-quality recycled paper.

  Furthermore, according to the present embodiment, the glue application roller 26A is separated from the drive roller 23 in the parallel direction (direction intersecting with the drive shaft 22 and the shaft portion 25A), that is, in the direction intersecting with the conveyance direction of the sheet P. Arranged in position. According to such a configuration, the glue application roller 26 </ b> A to which the glue 31 is attached does not contact the drive roller 23, so that the drive roller 23 is not soiled by the glue 31. Thereby, the maintenance burden can be reduced.

  Here, when the positions of the driving roller 23 and the glue application roller 26A are shifted, the sheet P sandwiched between the rollers 23 and 26A is wavy or wrinkled. Since the sheet P processed by the document processing apparatus 1 of the present embodiment is used for recycling, some undulations and wrinkles are allowed, but if the undulations and wrinkles become too large, the glue application roller There is a risk that the contact area between 26A and the sheet P will be reduced and adhesion failure will occur due to poor gluing, and prevention of information leakage will be hindered. In addition, if the arrangement position of the glue application roller 26A is biased, the gluing area on the sheet P is biased, and there is a possibility that the prevention of information leakage is hindered due to poor adhesion. Therefore, by adopting a structure in which the drive roller 23 and the plurality of glue application rollers 26A are alternately arranged, the waviness is minimized and the arrangement bias of the glue application roller 26A is eliminated. As a result, the sheet P can be reliably adhered and information leakage can be reliably prevented.

  Further, in the document processing apparatus 1 of the present embodiment, a holding device unit 41 that receives and holds the sheet P from the conveying device 20 after the glue application is provided, and the holding device unit 41 holds the punched processed holding. A plate 42 and an endless belt 47 circulated and driven in contact with the lower surface of the holding plate 42 are provided. The endless belt 47 is arranged with a plurality of narrow belts spaced apart so that the punching holes 43 of the holding plate 42 are opened between the adjacent endless belts 47. Furthermore, an air supply / exhaust device 44 is provided on the upper portion of the holding plate 42. According to such a configuration, the sheet P after the glue application is conveyed to a predetermined position by the endless belt 47 while being sucked and held by the holding plate 42 by the suction operation of the air supply / exhaust device 44. According to such a configuration, the paste 31 attached to the sheet P before bonding after the glue application does not contaminate other places in the apparatus housing 10 during the conveyance. Thereby, the maintenance burden can be reduced.

  A stock table 50 is disposed below the holding plate 42, and the stock table 50 is raised and lowered between a stacking position and a standby position by an elevating device 51. According to such a configuration, when the sheet P is bonded, the stock table 50 is lifted by pushing up the holding plate 42 by the operation of the lifting device 51. At this time, the entire holding device unit 41 held by the holding device frame F together with the holding plate 42 is pushed up, and the sheet P held by the holding plate 42 is loaded on the stock table 50 by its own weight. It is press-bonded to the protective paper placed or the processed sheet group P ′. As a result, the sheets P can be adhered to each other satisfactorily and information leakage can be reliably prevented.
