With a sheet presser equipped with a sheet presser that corrects in parallel by applying pressure to the processed sheet material that is discharged and stacked on the lifting / lowering tray. It relates to a flat plate punching machine.

  In this type of flat plate punching machine, for example, as in the flat plate punching machine 1 shown in FIGS. A sheet supply unit 1A is provided, and the sheet material 7a to be processed on the elevating sheet feeding table 2 is predetermined one by one from the upper end side of the elevating sheet feeding table 2 via a sheet feeding means by full-automatic, semi-automatic or manual feeding. The paper is sequentially fed to the start end side of the transport mechanism unit 1B at the timing.

  The transport mechanism unit 1B connects the main rotating body 10 and the driven rotating body 9 intermittently driven by a motor via a rotating shaft by the wrapping conduction means 6, and the wrapping conduction means 6 is connected in the transport direction. The latch holding means 11 for the sheet material is provided at predetermined intervals, and the latch holding means 11 is provided at least on the start side adjacent to the sheet supply unit 1A and the intermediate punching unit 1C and on the end side adjacent to the sheet discharge unit 1E. The winding conduction means 6 is caused to intermittently travel in a mode of resting at three places.

  The processed sheet material 7a is transported to the punching part 1C and temporarily stopped, and is fixedly punched by a fixed surface plate 3 having a molded wooden mold 5 attached to the lower surface and a movable surface plate 4 driven up and down by the lifting mechanism part 1D. After processing into a processed sheet material 7b by performing processing such as processing, the processed sheet material 7b is transported to the terminal end side of the transport mechanism unit 1B and sequentially discharged to the sheet discharge unit 1E having the lifting / lowering tray 8, and a predetermined number of sheets set in advance The processed sheet material 7b is stacked on the elevating / discharging tray 8 every time.

  The latch holding means 11 has a spike bar 12 installed between the outer surfaces of the winding conduction means 6, 6. A spike mounting plate 13 is provided on the spike bar 12 at a predetermined interval. 14 is protruded outward, and the spike bar 12 is provided at a plurality of locations (for example, 5 locations) for each intermittently fed pitch of the winding conduction means 6 that rotates endlessly. Cooperates with a holding plate (not shown) that rises in synchronization with the traveling movement toward the starting end side of the conveying mechanism section 1B, and the spike pin 14 is attached to the leading end side in the conveying direction of the processed sheet material 7a Lock and hold in a state where it is bitten.

  The processed sheet material 7a is sequentially conveyed to the punched portion 1C while being held and held by the spike pin 14 of the lock holding means 11, and the processed sheet material 7b processed by the punched portion 1C is also continuously spiked 14. In this state, the sheet is sequentially conveyed to the sheet discharge unit 1E side. However, on the sheet discharge unit 1E side, the spike pin 14 is removed from the processed sheet material 7b by the sheet removing mechanism 15 provided above the elevating / discharging tray 8. Are sequentially stacked on the elevating / discharging tray 8.

  The seat detaching mechanism 15 includes a rotating shaft 17 that is rotatably supported at both ends with respect to the main frame 16, a plurality of oscillating rotating arms 18 fixed to an intermediate portion of the rotating shaft 17, and a oscillating rotating arm 18. And the tip of the sheet removal plate 19 provided with a notch 19 a at a position aligned with the spike pin 14, the operation piece 20 attached to one end of the rotary shaft 17, and the operation piece 20. At the same time, it is composed of a connecting rod 21 that is moved forward and backward in conjunction with the lifting drive of the lifting mechanism 1D.

  In the sheet removing mechanism 15, the sheet removing plate 19 is normally held in a horizontal state at a position where the connecting rod 21 is retracted, and the processed sheet material 7 is conveyed above the lifting / lowering tray 8 and processed sheet material. When the connecting bar 21 moves forward and the operation piece 20 swings and rotates counterclockwise in synchronization with the timing at which the spike bar 12 that holds and holds 7 is aligned with the cutout portion 19a of the sheet removal plate 19. The sheet removing plate 19 is swung and rotated in a downward depression state via the rotating shaft 17 and the swinging and rotating arm 18, and the leading end side of the processed sheet material 7 b is pushed down by the sheet removing plate 19. The material 7b can be removed.

  The lifting / lowering tray 8 stands by at a preset uppermost position at the start of work, and thereafter, every time a predetermined number (for example, 10) of processed sheet materials 7b are stacked, the stacking thickness is increased. When the required number (for example, 100) of processed sheet materials 7b are stacked while repeating the lowering operation, the processed sheet materials 7b are lowered to a preset lowermost position, and these processed sheet materials 7b are bound or bound. In order to carry out this operation, an elevating drive control device 22 for the elevating / discharging tray 8 is provided.

  The elevating drive control device 22 is attached to the main frame 16 for guiding the lift material 23 connected to the upper surface of the elevating paper discharge tray 8, guide blocks 24 attached to both ends of the lift material 23, and the guide block 24. A guide shaft 25, a sprocket 26 attached to the main frame 16 and driven to rotate by a motor (not shown), one end connected to the lift member 23 or the guide block 24, and the other end connected to the counterweight 27 A chain 28 wound around the sprocket 26 and a control circuit (not shown) including a pair of projectors and light receivers attached to the main frame 16 to detect the uppermost processed sheet material 7b. Yes.

  The elevating drive control device 22 arranges a sensor (not shown) by a projector and a light receiver above the uppermost position of the elevating / discharging tray 8 and processes a predetermined number (for example, 10) on the elevating / discharging tray 8. When the sheet material 7b is stacked, it detects that the optical path of the projector and the light receiver is blocked by the uppermost processed sheet material 7b, generates a control signal, and rotates the motor with this control signal. The sprocket 26 is rotated, and the lift material 23 is lowered through the chain 28 by the predetermined number of thicknesses on the lifting / discharging tray 8 on which the processed sheet material 7b is stacked.

  However, when the sheet material 7 (the processed sheet material 7a and the processed sheet material 7b) is conveyed, if the spike pin 14 is inserted into the sheet material 7 and held, the outer periphery of the tip end side of the spike pin 14 is perforated. The cut end of the sheet material 7 bulges out, and this bulged portion remains on the outer peripheral edge of the perforation even after the spike pin 14 is removed from the sheet material 7. Since a thick portion of about 5 to 2 times is formed, if the sheet materials 7 are stacked one after another, as shown in FIG. There is a risk of disturbing work.

  In order to prevent this, conventionally, every time a predetermined number of processed sheet materials 7b are stacked, an operator presses the sheet to correct the deformation. However, it is difficult to correct it evenly by a manual pressing force. However, since it is performed while the flat plate punching machine is in operation, there is a risk that it may be dangerous, and it is necessary to always have a worker who performs correction work, so that labor costs are required.

  The present invention provides a flat plate punching machine with a sheet pressing device that can solve the problems of the prior art, and at the same time as the removal of spike pins without requiring manual labor, the processed sheet material is made uniform. It is possible to automatically perform a correction operation in a parallel state, and to perform the correction operation easily with a simple and inexpensive configuration.

  The flat plate punching machine with a sheet pressing device according to the present invention has a spike pin attached to a conveyance mechanism section that intermittently travels in an endless manner via a spike bar, and the spike pin is inserted into a processed sheet material on the sheet supply section side. After the processed and held sheet material is transferred to the punching portion and processed, the processed sheet material is transferred to the sheet discharge portion side and removed from the spike pin, and the processed sheet material is moved onto the lifting / discharging tray. The target is to implement a flat plate punching machine.

  In the flat plate punching machine, on the sheet discharge part side, the processed sheet material is pressed from above and removed from the spike pin, and the processed sheet material pulled out on the lifting / discharging tray is pressed from above, There is provided a sheet pressing device for correcting the bulging portion caused by the trace of the spike pin to be flat.

  In the prior art, the processed sheet material is simply removed from the spike pin by the sheet removing mechanism and pulled out onto the lifting / discharging sheet tray in the prior art, but the removed processed sheet material is pressed against the spike pin. The sheet correction function which corrects the bulging part by the trace of this to flat is newly added.

  The sheet pressing device can take a form including a lifting plate that descends in synchronization with the processed sheet material being intermittently transferred to the sheet discharge portion side by the transport mechanism. Can be lowered, and after removing the processed sheet material from the spike pin, the processed sheet material can be continuously lowered and pressed onto the lifting / discharging tray.

  In these forms, the processed sheet material can be removed from the spike pin by lowering the elevating plate, and the processed sheet material that has been dropped onto the elevating / discharging tray is pressed to flatten the bulging portion due to the trace of the spike pin. Although it is possible to correct the sheet removal function and the sheet correction function by using separate lifting plates, it is more desirable to use both functions with a common lifting plate.

  According to the flat plate punching machine with a sheet pressing device of the present invention, the sheet correction work that has been performed manually by an operator can be performed automatically and uniformly by the sheet pressing device, and the work efficiency is improved. It is possible to reduce labor costs, and the sheet removal work and the sheet correction work can be easily achieved by a simple and inexpensive means for moving the lifting plate up and down. By adopting a form in which both functions are combined, this can be achieved by a simpler and cheaper means.

  A flat plate punching machine with a sheet pressing device according to the present invention will be described in detail with reference to the accompanying drawings of FIGS. 4 to 8 showing a preferred embodiment to which the present invention is applied. FIG. 5 is a perspective view of the sheet pressing device, FIG. 6 is an enlarged front view of the main part of the sheet pressing device, and FIG. 7 is an enlarged side view of the main part of the sheet pressing device. FIG. 8 shows a sheet correction state by the sheet pressing device.

  The sheet pressing device in this embodiment uses a flat plate punching machine 1 having the same configuration as that of the prior art described with reference to FIGS. 1 to 3, and a sheet removing mechanism 15 provided adjacent to the sheet discharge unit 1E. The sheet correction function is newly added by changing the section, and the configuration of the main body side of the flat plate punching machine 1 is the same as in the case of the prior art. Therefore, detailed description will be omitted, and detailed description will be given of the changed and added components.

  As shown in FIG. 4, the rotary shaft 17 is mounted between the both side plates of the main frame 16 on the sheet discharge portion 1 </ b> E via a bearing member 29, and the connecting rod 21 is pushed and pulled at one end of the rotary shaft 17. The operating piece 20 that is swung and rotated by the motor is mounted, and the driven rotor 9 is connected to a main rotor 10 (not shown) that is intermittently driven by a motor by a winding conduction means 6 and both sides are wound. Between the conducting means 6 and 6, a locking holding means 11 composed of a spike bar 12, a spike mounting plate 13 and a spike pin 14 is mounted at predetermined intervals.

  FIG. 5 shows a sheet pressing device 30 that also serves as a sheet removal mechanism. The rotation shaft 17 is longer than the swing rotation arm 18 in the prior art so that the sheet can be corrected after the sheet is removed. As shown in FIGS. 6 to 8, the guide protrusion 32 having a cylindrical shape is provided on the distal end side of the swing rotation arm 31. 32 is engaged in a U-shaped guide groove 35 of a movable block 34 attached to the elevating plate 33.

  The sheet pressing device 30 is provided with a pressing piece 33a in which the lower end side of the elevating plate 33 is bent in an L shape, and the pressing piece 33a has a notch 33b at a position aligned with the spike mounting plate 13 on which the spike pin 14 is mounted. A lifting guide block 36 is attached to the lifting plate 33, and a lifting guide shaft 37 is inserted into the lifting guide block 36, and the upper and lower ends of the lifting guide shaft 37 are connected to the main through support plates 38 and 39. It is supported on both side plates of the frame 16.

  The sheet pressing device 30 is normally in a state in which the connecting rod 21 is pulled back as shown by the white arrow in FIG. 5, and in that case, as shown in FIG. 7, the lifting plate 33 has a preset lifting range. When the processed sheet material 7a, which is located at the upper limit but is locked to the spike pin 14 of the locking holding means 11, finishes the processing and is intermittently transferred to the sheet discharge portion 1E side as the processed sheet material 7b. In synchronism with this, the connecting rod 21 is pushed out as indicated by a black arrow and the rotating shaft 17 rotates counterclockwise, and the swinging rotary arm 31 swings and rotates in the same direction.

  As a result, the guide protrusion 32 provided on the distal end side of the swinging and rotating arm 31 pushes down the lifting plate 33 via the movable block 34. At this time, the lifting plate 33 is pushed down in the vertical direction so that the lifting plate 33 is pushed down in the vertical direction. The attached elevating guide block 36 is guided while sliding along the elevating guide shaft 37, and the elevating plate 33 is lowered while passing through the spike mounting plate 13 by the notch 33b, and the processed sheet material 7b is pushed by the pressing piece 33a. The processed sheet material 7b can be pulled down onto the lifting / lowering tray 8 by being pushed down and removed from the spike pin 14.

  Further, the elevating plate 33 continues to descend and presses the processed sheet material 7b that has been removed just before, and compression is performed between the processed sheet material 7b already stacked on the elevating / discharging tray 8. Therefore, it is possible to correct the deformation of the bulging portion caused by the trace of the punched hole of the spike pin 14 and to stack the processed sheet material 7b on the lifting / lowering delivery table 8 in a uniform parallel state. However, the sheet pressing device having the lifting plate 33 having both the sheet removal function and the sheet correction function as in the illustrated embodiment can be safely and automatically performed efficiently, and the structure is simple and inexpensive. Can be provided.

In addition, the sheet pressing device can take various modifications.

  For example, the sheet pressing device only needs to include a lifting plate that descends in synchronization with the processed sheet material when the processed sheet material is intermittently transferred to the sheet discharge portion by the transport mechanism, so that the lifting plate is moved up and down. As well as the conventional technology, the seat removal mechanism has a small lifting movement range so that it can take various known raising and lowering movements, and the seat removal function and the sheet correction function can be performed by separate lifting plates. The sheet correction mechanism can also take a form using a lift plate having a large lift movement range.
