A paper stacking apparatus for printing device
[9] The present invention relates to a discharge paper stacking device for a printing press, and more particularly, to a discharge paper stacking device for a printing press having an improved structure for sorting the discharged paper.
[10] Generally, a printer 12 such as a printer or a copying machine is provided with a tray 12 as a discharge paper stacking device for stacking paper discharged through the discharge port 11, as shown in FIG. That is, the paper pushed out by the discharge roller 13 in the printer 10 is stacked on the tray 12 in turn, and the user arranges the paper loaded on the tray 12 after the printing operation is finished. By the way, since it is quite cumbersome to arrange the discharged paper every time a print job is performed, conventionally, the rotation bar 14 as shown in the drawing is used in addition to the discharge paper stacking device in order to automatically align it. The rotation bar 14 is driven by a drive unit (not shown) installed in the printer 10 and rotates along an arc of the drawing. In this case, the paper loaded on the tray 12 is rotated on one sidewall ( 12a). Therefore, if the rotation bar 14 is rotated once each time the paper is discharged, the stacked paper is stacked while being aligned with respect to one side wall 12a of the tray 12, so that there is no need to arrange it later. .
[11] By the way, in order to employ such a rotation bar 14, the drive unit for driving it must be installed in the printer 10, and also the sensor for confirming discharge completion must be provided, so that the number of parts increases a lot. There is a disadvantage that the structure of the earth 11 side becomes very complicated. And since the rotation bar 14 is rotated every time paper is discharged, energy consumption at the time of a printing operation will also increase.
[12] Therefore, there is a need for a discharge paper stacking device capable of stacking and arranging papers with a simpler structure.
[13] SUMMARY OF THE INVENTION The present invention has been made in view of the above necessity, and an object thereof is to provide an output paper stacking device of a printing press that has a simple structure without using power and can be loaded evenly.

[15] Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
[16] 2 and 3 show the discharge paper stacking apparatus of the printing press according to the first embodiment of the present invention.
[17] As shown, the discharge paper stacking apparatus of the present embodiment, first, the tray 121 is installed below the discharge port 110 of the printer 100, the paper discharged through the discharge port 110 is sequentially stacked thereon ). In addition, guide levers 123 and 124 having one end protruded upward through the through slot 121a formed in the tray 121 are provided, and the guide levers 123 and 124 are provided on the bottom surface of the tray 121. It is rotatably supported by the shaft 122, and on the other end side, center weights 123a and 124a are provided integrally for balancing weight. The guide levers 123 and 124 are balanced by the center weights 123a and 124a in the protruding state above the tray 121 to maintain balance. Therefore, even though the guide levers 123 and 124 are intentionally pushed into the through slot 121a, after the external force is removed, the guide levers 123 and 124 are returned to their original state by the weight of the center weights 123a and 124a. However, the guide levers 123 and 124 rotate into the through slot 121a while being rotated whenever a load is applied. The pair of guide levers 123 disposed inside of the guide levers 123 and 124 is used when a small size of paper is discharged, and the pair of guide levers 124 disposed on the outside of a paper of a large size Is used when is discharged. That is, the two guide levers 123 and 124 are set at intervals so as to correspond to the widths of the standard papers, and the two guide levers 123 and 124 guide the papers to a predetermined stacking position so that the papers are stacked. Reference numeral 130 denotes a discharge roller which pushes the paper through the discharge port 110.
[18] In the above configuration, in the case of printing and discharging the small-size paper S1 from the printer 100, as shown in FIG. 2, the two pairs of guide levers 123 and 124 are placed on the tray 121. Protruding and balancing. When the paper S1 is discharged through the discharge port 110 in this state, both sides of the paper are guided between the guide levers 123 of the guide levers 123 and 124 and are seated on the tray 121. Therefore, since all the paper S1 discharged from the outlet 110 of the printer 100 is guided and seated between the protruding ends of the guide lever 123, it is always maintained neatly aligned.
[19] In addition, when discharging the large size paper S2 from the printer 100, as shown in FIG. 3, the outer guide lever 124 guides the paper S2. That is, when the paper S2 having a large size is discharged through the discharge port 110, both sides of the paper are guided between the outer guide levers 124 to be seated in an aligned state on the tray 121. At this time, when the paper S2 is loaded on the tray 121, the inner guide lever 123 is pressed by the weight of the paper to enter the through slot 121a. Therefore, the inner guide lever 123 is naturally entered by the weight of the paper without any additional work to insert into the through slot (121a).
[20] As described above, the discharge paper stacking apparatus of the present invention can guide and align the paper with a guide lever meeting the paper standard without using any power.
[21] 4 and 5 show a discharge paper stacking apparatus according to a second embodiment of the present invention.
[22] This embodiment is basically the same as that of the first embodiment described above. However, the directions of the guide levers 223 and 224 rotatably supported by the shaft 222 and the center weights 223a and 224a are different from those of the first embodiment. In this case, the guide levers 223 and 224 may be in equilibrium with the guide slots 221a protruding upward from the tray 221.
[23] In the above configuration, in the case of printing and discharging the small-size paper S1 from the printer 100, as shown in FIG. 4, the two pairs of guide levers 223 and 224 are placed on the tray 121. Protruding and balancing. When the paper S1 is discharged through the discharge port 110 in this state, both sides of the paper are guided between the guide levers 223 inside the guide levers 223 and 224 and are seated on the tray 221.
[24] In addition, in the case of discharging the paper S2 having a large size from the printer 100, as illustrated in FIG. 5, the outer guide lever 224 guides the paper S2. That is, when the paper S2 having a large size is discharged through the discharge port 110, both sides of the paper are guided between the outer guide levers 224, and are seated in an aligned state on the tray 221. At this time, the inner guide lever 223 is pushed by the leading end of the paper (S2) discharged from the discharge port 110 into the through slot (221a). Of course, even if the paper S2 is not exactly pushed into the front end, when the paper is loaded on the tray 221, the paper enters the through slot 221a by its weight. Therefore, even if the positions of the guide lever and the center weight are arranged opposite to those of the first embodiment, it can be seen that the sheets can be guided and aligned smoothly.
[25] 6 and 7 show a discharge paper stacking apparatus according to a third embodiment of the present invention.
[26] In the present embodiment, the shaft 322 rotatably supporting the guide levers 323 and 324 is installed inside the printing machine 100, so that the center weight 323a for holding the center of the guide levers 323 and 324 is provided. ) 324a is also arranged to enter the printer 100, and accordingly, the guide levers 323 and 324 protruding through the through slot 321a also have a rotating direction through the through groove 100a. It is configured to rotate in and out of 100. In general, the tray 321 inclines the discharge port 110 side lower than the opposite side to prevent the paper from falling to the bottom. Therefore, the paper stacked thereon is slid down toward the discharge port 110 side to be stacked, and the present embodiment is configured to rotate the inner guide lever 323 using it.
[27] First, in the case of printing and discharging the small size paper S1 from the printer 100, the paper is disposed between the inner guide levers 323 of the two pairs of guide levers 323 and 324 as shown in FIG. Both sides of S1 are guided.
[28] On the other hand, when discharging the large size of paper (S2) in the printer 100, as shown in Figure 7, the outer guide lever 324 guides both sides of the paper (S2). However, since the paper S2 discharged from the discharge port 110 exits in the direction of arrow A and slides down in the direction of arrow B along the inclination of the tray 321, the inner guide lever 323 is It is pushed out of the tray 321 by the rear end of the paper coming down in the arrow B direction. Therefore, the paper S2 is guided and loaded by the outer guide lever 324 in a state where the inner guide lever 323 does not interfere.
[29] Therefore, by arranging the guide lever of the simple structure which keeps a balance by the center weight in this way, it is possible to smoothly guide the paper without using power.
[30] On the other hand, in the present embodiment, the size of the paper discharged from the printing machine has been exemplified in two types, small and large, according to the specification of the printable paper can also be installed by corresponding to the guide lever of course.
[31] As described above, the discharge paper stacking device of the printing press according to the present invention guides and sorts the paper discharged from the printing press with a guide lever of a simple structure, thereby simplifying the structure and using no power at all. It has the effect of reducing energy consumption.
[32] It is to be understood that the invention is not limited to that described above and illustrated in the drawings, and that more modifications and variations are possible within the scope of the following claims.
