DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE ART
The present invention relates to a paper jogging apparatus for stacking a multiplicity of paper sheets while aligning corners thereof.
BACKGROUND ART
When printing paper sheets on a printing machine at a prescribed position on the paper sheets under the same conditions, it is necessary that the corners of the paper sheets be aligned. For cutting paper sheets of different sizes to the same dimentions, it is necessary to align at least two edges of the paper sheets. Heretofore, since such a paper jogging process has entirely been effected manually, the process has been quite laborious and time-consuming, and it has been rather difficult to align paper sheets uniformly.
DISCLOSURE OF THE INVENTION
It is an object of the present invention to provide a paper jogging apparatus which will eliminate the above disadvantages and can pile paper sheets while automatically and uniformly aligning corners thereof simply by successively stacking the paper sheets downwardly.
BRIEF DESCRIPTION OF THE DRAWINGS
FIGS. 1 and 2 are perspective views showing the manner in which a paper jogging apparatus is in use;
FIG. 3 is a lefthand side elevational view of the paper jogging apparatus;
FIG. 4 is a righthand side elevational view of the paper jogging apparatus;
FIG. 5 is a schematic plan view;
FIG. 6 is a schematic view of a lifter;
FIG. 7 is a schematic view of a paper holder;
FIG. 8 is a perspective view of an arm;
FIG. 9 is a set of plan views of an arm;
FIG. 10 is a schematic view of another embodiment of a tiltable body;
FIG. 11 is a plan view of another embodiment of a means for lifting and lowering an up-down table; and
FIG. 12 is a front elevational view of the lifting and lowering means.
BEST MODE FOR CARRYING OUT THE INVENTION
Embodiments of the present invention will hereinafter be described with reference to the drawings.
As shown in FIGS. 1 through 4, a paper stacking and jogging apparatus according to the present invention comprises a base frame body 1, a tiltable body 2 supported on the base frame body 1 and tiltable with respect thereto, an up-down table 3 vertically movably attached to the tiltable body 2, and vibratory plates 4 mounted on an upper portion of the tiltable body 2 for jogging paper sheets.
As illustrated in FIGS. 1 through 5, the base frame body 1 has main frames 5 extending symmetrically horizontally at a prescribed angle and placed on a ground A or the like, a support post 6 extending upwardly at the center of the horizontally extending main frames 5 and supporting the tiltable body 2 in a tiltable manner, lifters 7 vertically movable on distal ends of the main frames 5 for lifting the opposite ends of the tiltable body 2 to tilt the same about the support post 6, and a tilting motor 8 for vertically moving the lifter 7.
The tiltable body 2 is tiltably supported on the support post 6 by means, for example, of a ball 6a mounted on the upper end of the support post 6, and a spherical bearing 2a mounted on the tiltable body 2 and holding the ball 6a therein, the tiltable body 2 being tilted when the spherical bearing 2a is tilted over the surface of the ball 6a. As shown in FIGS. 3 and 4, the tiltable body 2 is tiltably supported on the support post 6 in the vicinity of a substantially central portion of the tiltable body 2.
As shown in FIGS. 1 though 4 and FIG. 6, each lifter 7 is composed of a vertically movable rack 9 and a grooved roller 11 angularly movably mounted by a pin 10 on an upper end of the rack 9. The roller 11 is movably held in engagement with a ridge 12 mounted on each of ends of vertial frames of the tiltable body 2. The racks 9 are disposed parallel to the main frames 5 and held in mesh with gears 15, 16 mounted on distal ends of shafts 13, 14 rotatable by the tilting motor 8.
As shown in FIGS. 2 through 5, the tiltable body 2 comprises horizontal frames 17 extending parallel to the main frames 5, and a plurality of vertical frames 18 extending perpendicularly to the horizontal frames 17. Opposite ones 18a, 18b of the vertical frames 18 have the rid
