Description

  The present invention relates to a stacker device for a printer, and more particularly to a stacker device in which printing sheets are formed in a single-leaf shape and stacked.

The stacker device is installed on the downstream side of the printer, and sequentially stacks the single-leaf printed material on which predetermined information is printed by the printer and cut into a predetermined length, thereby facilitating the subsequent handling.
The single-leaf printed matter sequentially discharged from the printer discharge port is drawn by the pulling mechanism of the stacker device, and the side edge is brought into contact with the side plate supported on the bottom plate. As a result, the single-leaf printed material is laminated on the bottom plate.
By the way, when taking out the laminated single-leaf printed matter, in general, various functions of the printer are stopped and the pull-in mechanism of the stacker device is stopped, and then the bottom plate of the stacker device and the top of the laminated single-leaf printed matter are stopped. A finger is put between the lower part and the single-leaf printed matter is lifted and taken out.
In addition, in a stacker device for cutters of large printed products, in which the stacker table on which the printed products are stacked moves up and down, a fall prevention bar is installed at the bottom of the stacker table, and the stacked printed products are (See Patent Document 1).

  FIG. 2 is a perspective view of the stacker device 4 with the side plate 32 removed from the bottom plate 31 of the stacker device 4. Refer to FIG. 1 and FIG. 2 below.

  The entrance portion 15 of the stacker device 4 is provided with an upper drawing roller 40, a lower drawing roller 20 that is rotationally driven by the drive motor 21, and an endless belt 22 that is wound around the lower drawing roller 20.

  As shown in FIG. 3, the weight member 33 presses the stacked single-leaf printed material 10 from above, and includes a weight 33a and a pressing plate 33b fixed to the lower portion of the weight 33a. The weight 33a is fitted with a pin or the like into the slit 23 formed in the stacker housing 24 in the vertical direction.

  FIG. 4 is a schematic cross-sectional view of the stacker housing 24 illustrating the printed matter lifting mechanism 30, and the alternate long and short dash line portion indicates a case where the printed matter lifting member 30 c moves upward.

  The printed matter lifting mechanism 30 includes an operating rod 30a, an operation knob 30e, an operation shaft 30b, and a printed matter lifting member 30c. The operating rod 30a is installed so as to be movable in the vertical direction on the side surface of the stacker housing 24, for example, and an operation knob 30e is attached to the vicinity of the upper end of the operating rod 30a via a connecting member 35. The operation shaft 30b is connected to a first end portion 30b1 on one end side of the operating shaft 30b so that the lower end of the operating rod 30a is rotatable, and a printed material lifting member 30c is connected to a second end portion 30b2 on the other end side.

The operation shaft 30b is supported by a support portion 34 installed on the stacker housing 24 below the bottom plate 31 so as to be rotatable in a vertical plane. The support portion 34 has, for example, a main body attachment portion 34a attached to the bottom of the stacker housing 24 by welding or the like, and a rotation support portion 34b integrally formed with the attachment portion 34a.
More specifically, the operation shaft 30b has a substantially intermediate position in the longitudinal direction and a rotating portion at the first end portion 30b1, and a fulcrum 30d that is a rotating portion at the approximately intermediate position in the longitudinal direction has the rotation point. The moving support portion 34b is pivotally supported by a rotation pin 36 so as to be rotatable in a vertical plane.

  A first long hole 25 and a second long hole 26 are formed in the side surface portion of the stacker housing 24 so that the connecting member 35 and the operation shaft 30b can be moved up and down.

  The guide 37 is provided on the side surface portion of the stacker housing 24, and the operation rod 30a is inserted therethrough.

  As shown in FIG. 2, the bottom plate 31 is formed with a through hole 41 through which the printed material lifting member 30c can protrude. The stacked single-leaf printed material 10 is lifted by the protrusion of the printed material lifting member 30c. The position where the through hole 41 is formed, that is, the protruding position of the printed material lifting member 30c is located between the side plate 32 and the weight member 33 at the side plate 32 side, between the side plate 32 and the weight plate 33.

Below, operation | movement of the stacker apparatus 4 is demonstrated.
The single-leaf printed matter 10 sequentially discharged from the printer main body 3 is drawn in the direction of the side plate 32 that is sandwiched between the upper drawing roller 40 and the endless belt 22 and is erected on the bottom plate 31. The drawn single-leaf printed material 10 is inserted between the bottom of the single-leaf printed material 10 already stacked on the bottom plate 31 and the bottom plate 31, and the side edge at the leading end side in the drawing direction comes into contact with the side plate 32. In this way, the single-leaf printed matter 10 printed by the printer main body 3 is sequentially stacked on the bottom plate 31.

The operation of the printed matter lifting mechanism 30 will be described with reference to FIGS.
First, the operation knob 30e installed on the side surface portion of the stacker housing 24 is lowered downward from the upper end of the first long hole 25. As a result, the operating rod 30a connected by the operating knob 30e and the connecting member 35 descends, and the first end 30b1 of the operating shaft 30b connected to the lower end of the operating rod 30a moves downward.

  The operation shaft 30b is pivotally supported by a support portion 34 so that a fulcrum 30d at a substantially intermediate position can be rotated in a vertical plane. With this configuration, the second end of the operation shaft 30b opposite to the first end 30b1 is supported. The portion 30b2 is moved upward against the tension of the tension spring 38 installed in the vicinity of the second end. The printed material lifting member 30c is connected to the second end portion 30b2, so that the printed material lifting member 30c protrudes through the through hole 41 from below the bottom plate 31 to lift the stacked single-leaf printed material 10 on the bottom plate 31. . As a result, a gap is formed between the bottom of the laminated single-leaf printed material 10 and the bottom plate 31.

  In the state shown in FIG. 3 in which the printed material lifting member 30c protrudes from the upper portion of the bottom plate 31, a case where a single-leaf printed material 10 is issued or only one sheet is removed from the bottom of the stacked single-leaf printed material 10 is issued. These can be easily performed even in the take-out.

  The weight 33a is fitted to the slit 23 formed in the stacker housing 24 in the vertical direction with a pin or the like. Thereby, the weight member 33 can move along the slit 23 according to the stacking height of the single-leaf printed material 10, and the collapse of the stacked single-leaf printed material 10 can be prevented.

  A first long hole 25 and a second long hole 26 are formed in the side surface portion of the stacker housing 24 so that the connecting member 35 and the operation shaft 30b can be moved up and down. As a result, the operation rod 30a and the operation shaft 30b operate according to the operation of the operation knob 30e. A tension spring 38 is installed in the vicinity of the second end 30b2 of the operation shaft 30b, with the bottom and one end connected to the stacker housing 24. Thereby, when the operation knob 30e is not operated, the operation rod 30a and the operation shaft 30b are forcibly pulled back to the positions indicated by the solid lines in FIG.

  Since the guide 37 is provided on the side surface of the stacker housing 24, the vertical movement of the operating rod 30a is stabilized.

  Since the formation position of the through hole 41, that is, the protruding position of the printed material lifting member 30 c is located between the side plate 32 and the position where the weight member 33 contacts the bottom plate 31 and on the side plate 32 side, the vertical surface of the weight member 33 And the single-leaf printed material 10 can be lifted with a small force. Further, even when the single-leaf printed material 10 is taken out after the weight member 33 is placed on the slit 23, the weight member 33 is lifted with a small force similarly to the above because it is out of the center of gravity of the laminated single-leaf printed material 10. It is done.

  For example, when the second end portion 30b2 of the operation shaft 30b is configured to protrude from the through hole 41 by the series of operations, the same action as described above can be performed without installing the printed matter lifting member 30c. And effects are obtained.

  Further, for example, the printed material lifting member 30c may be installed in the lower portion of the through hole 41 so as to be vertically movable without being connected to the second end 30b2 of the operation shaft 30b. In this case, by the series of operations, the second end 30b2 of the operation shaft 30b pushes up the lower end of the installed printed matter lifting member 30c. And the same effect as the above is acquired because the upper end of the printed matter lifting member 30c protrudes from the through-hole 41. Furthermore, since the printed material lifting member 30c does not move in the lateral direction, the risk of damaging the printed material during lifting is reduced.

  FIG. 5 shows an embodiment in which the printed material lifting member 30c is installed in the vicinity of the standing position of the side plate 32. When installed at such a position, a portion close to the end side of the laminated single-leaf printed material 10 is lifted, so that it is more convenient to take them out.

  By the way, in FIG. 1 thru | or FIG. 5 which shows embodiment of this invention, the operation knob 30e is installed in the upper part inner side of the right side stacker housing 24 seeing the stacker apparatus 4 from the printer main body 3 side. However, the installation position of the operation knob 30e is not limited to this position. For example, the operation knob 30e may be installed outside the side surface of the left stacker housing 24 when the stacker device 4 is viewed from the printer body 3 side. When installed at this position, the operation knob 30e can be operated in front of the stacked single-leaf printed material 10, so that the lifting operation is facilitated.

  The various shapes, dimensions, and the like of the constituent members shown in the embodiment are merely examples, and various changes can be made based on design requirements, and such changed structures are also within the scope of the present invention. This will be understood by those skilled in the art.
