Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a high-pile paper aligning device that can stack a large number of sheets of paper in high piles (stacks) with their corners aligned.

For example, when printing on paper using an automatic printing machine, in order to print under the same conditions, it is necessary to align the corners of each sheet of printing paper and set it, and paper of different sizes must be set to the same size. In order to cut, it is necessary to align at least two sides of each sheet of paper, but in the past, all of this paper alignment work was done manually, which required a lot of manpower and time. There was a problem that the efficiency was poor and it was difficult to align the paper evenly.

Therefore, as a method for automating the above-mentioned paper alignment, the paper alignment machine described in Utility Model Application Publications No. 53-50985 and 53-50986 has already been proposed by the present applicant. The paper aligner is configured to simply position and stack the sheets one by one on an inclined table, so it is only possible to stack a certain number of sheets, and it is not possible to stack many sheets of paper in a high pile (stick stacking). ) could not be done.

The present invention was developed in view of the above-mentioned points, and its purpose is to automatically and uniformly align the edges of the stacked papers by simply stacking the papers sequentially from above. To provide a high stack paper aligning device devised so that high stacks of paper can be stacked in high condition.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view of sheets P piled up in a high pile with the corners aligned on a pallet F for a fork lift according to the present invention, and the sheet P of the present invention can be stacked in a high pile in this way. The alignment device is constructed as shown in FIGS. 2-5.

That is, what is generally indicated by the reference numeral 1 in FIGS. 2 to 4 is the machine frame body made vertically as a whole, and this machine frame body 1 includes a bottom plate 2 and the left and right sides of this bottom plate 2. It is composed of a plurality of pillars 3 (actually 6 in total) erected upward on both sides at intervals, and a sky frame body 4 attached to the top end of each of these pillars 3. The entire top frame body 4 is made up of left and right frame plates 4a,

Reference numerals 18, 19, and 20 are vibration motors attached to the left and right front and side surfaces of the machine frame 1, respectively. Eccentric rollers 17... are attached.

Further, 21 is a pipe (rubber hose) for blowing air arranged inside the above-mentioned ceiling frame body 4, and a plurality of air blowing pipes (actually 6 pieces in total) are installed at appropriate positions of this pipe 21 in the direction of the lifting table 8. Nozzles 22... are attached, and the sheets P stacked on the lifting table 8 are prevented from adhesion due to static electricity by receiving the air ejected from these blowing nozzles 22...
In addition, the alignment work by the diaphragms 16 can proceed smoothly. Furthermore, in the drawing, 23 and 24
are limit switches for upper and lower limits provided on the lifting path of the lifting table 8;
When these switches 23 and 24 come into contact, the power supply circuit of the lifting motor 14 is opened, and the lifting table 8 can be stopped at the upper limit point or the lower limit point. Further, reference numerals 25 and 25 are micro switches for paper alignment provided on the left and right upper portions of the elevating passage of the elevating table 8. When the paper P stacked on the elevating table 8 contacts this switch 25 and turns on, the motor 14 is activated. Rotate slightly forward and lift table 8
It is designed so that it can be lowered by a predetermined width.

Next, the structure of the tilting means that supports the machine frame 1 from below and can tilt it diagonally backward as shown by the imaginary lines in FIGS. 2 and 4 will be described.

In the figure, 26 is a board placed directly on the floor surface, and the tilting means configured on this board 26 is
As shown in Figures 2, 4, and 5A and B,
A pair of left and right tilting motors 27, 28, interlocking gears 29, 30 that mesh with and rotate in conjunction with drive gears 27a, 28a of the motors 27, 28, and eccentric gears 29, 30 that are eccentric to the sides of the interlocking gears 29, 30. The left and right eccentric disks 32, 33 are configured with bolts 31...
The upper peripheral surface of 33 is configured to support support rollers 34 and 35 attached to the left and right bottom surfaces of the bottom plate 2 from below. The detailed structure of the support rollers 34 and 35 will be explained based on FIG. 5A and FIG. 5B. One of the support rollers 34 is as shown in FIG. 5A.
Flange pieces 3 sandwiching the periphery of the eccentric disk 32 from both sides.
4a and 34b, and the spherical portion 3 of the roller shaft 36a is horizontally suspended on a bearing 36 fixed to the bottom plate 2.
It is attached to the part 6b so that it can rotate freely and also swing freely from side to side. The other support roller 35 is provided with collar pieces 35a and 35b on both sides as shown in FIG. 5B, and has a bearing 3 fixed to the bottom plate 2.
A slide roller shaft 36a' which is horizontally movably mounted on the spherical part 36b' of the slide roller shaft 36a' is rotatably mounted on the spherical part 36b' of the slide roller shaft 36a'
Moreover, it is attached so that it can swing freely from side to side,
It is configured to move laterally together with the slide roller shaft 36a'. Moreover, 37 and 38 are the above-mentioned left and right interlocking gears 29, 30 and eccentric disks 32, 33.
39, 40 are the shafts 37, 38
, and 41 and 42 are interlocking gears 2.
When the eccentric disks 32 and 33 rotating together as 9 and 30 reach the lowest point, the limit switch is pushed to stop the tilting motors 27 and 28.

The reason why the support rollers 34 and 35 are universally supported as described above is to prevent the support rollers 34 and 35 from coming off the eccentric disks 32 and 33 when the machine frame 1 is tilted. In the present invention, it is possible to freely tilt the machine frame 1 in either the left or right direction.

Further, 43 is a flexible support that supports the center of the bottom plate 2 on the base plate 26, and when this flexible support 43 is connected to the installation points of the left and right eccentric disks 32 and 33, a triangle is formed. . Support rods 44 and 45 stand on the upper front surface of the base plate 26, and support the front bottom surface of the bottom plate 2 when the machine frame 1 is in a horizontal state as shown.

In FIG. 2, 46 and 47 are loading tables provided on both sides of the machine frame 1, and 48 and 49 are used to restart the tilting motors 27 and 28, and the vibration motors 18 and 19. , 20 for operation, and 50 indicates a blower for supplying air to the air blowing pipe 21.

Next, an example of the operation of the present invention will be explained based on the drawings.

In use, first use the tilting means to tilt the machine frame 1.
Tilt the entire body diagonally rearward to either the left or right. That is, if you want to tilt the machine frame 1 diagonally backward to the left in FIG. When rotated by 180 degrees, the fulcrum of the support roller 34 gradually descends, so that the entire machine frame 1 tilts backward as shown by the imaginary line in FIG. 3 and to the left in FIG. The angle of inclination in this case is, for example, about 12 degrees. The entire machine frame 1 tilted in this way is supported by the right support roller 3.
5 and the engagement action of the eccentric disk 33, and the flexible receiver 4
Tilting is prevented at two points in 3.

Once the machine frame 1 has been tilted to the left as described above, the user can then step onto the left stand 46 and stack an appropriate number of sheets P on the pallet F placed on the lifting table 8. When stacking, the positioning pillar 15 attached to the left frame plate 4a of the ceiling frame body 4...
The positioning pillars 15, which are also attached to the rear frame plate 4c, position each side of the left side and rear side of the paper P according to the inclination of the machine frame 1, that is, the lifting table 8, and therefore, The corners of the paper P on the lifting table 8 are naturally aligned. In this case, it goes without saying that the vibration caused by the diaphragm 16 and the air blown out from the blower nozzles 22 further promote the alignment effect.

When the above-mentioned stacking of paper continues and the top surface of the stacked paper touches the micro switches 25, 25, the lifting motor 14 is driven and the screw rod 1
1 to lower the lifting table 8 a little.
After repeating the stacking of sheets P in this manner several times, the elevating table 8 finally presses the lower limit switch 24 to stop the descent, thereby completing the high stacking of sheets P.

When the above work is completed, operate the switch panel 48 again to drive the tilting motor 27, return the machine frame 1 to its original horizontal state, and use a forklift from the front to lift the pallet F together with the pallet F as shown in Figure 1. All the work is completed by taking out the stacked sheets of paper P. It goes without saying that even when the machine frame 1 is tilted to the right by driving the right tilting motor 28, a similar high stack of sheets P can be obtained.

Since the present invention is as described above, all that is required is to tilt the machine frame obliquely backward and load sheets of paper one after another on the tilted elevating table.
It is possible to stack the sheets while aligning them, but in the present invention, in particular, it is possible to stack the sheets while aligning the sheets according to the inclination of the machine frame and the interval lowering of the elevating table. It is possible to stack paper sheets at approximately the same height, which is different from the conventional method of stacking paper sheets by manually aligning them one by one, or by tapping the sides with a board or the like. Compared to the high stacking method, the work is much simpler, and anyone can easily and accurately arrange and stack a large number of sheets in a high stack, contributing to labor savings in the high stacking process.
