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 aligning machine has a structure that only stacks paper one after another on an inclined table, so it can only stack a certain number of sheets, and it is difficult to stack many sheets of paper in high piles (stack). I couldn't do it.

In addition, simply tilting the table will not properly align the corners of the sheets, so it may be possible to vibrate the stacked sheets to ensure that the corners are perfectly aligned.
The former publication also discloses that vibration means are provided.

However, with the vibrating means described in this publication, since the vibrating plate moves horizontally forward and backward to vibrate the stacked sheets, as the number of sheets increases, the load increases and corner alignment cannot be performed reliably. It was hot. In addition, there was a problem in that static electricity was generated due to friction between the stacked sheets, and even when vibrated with a diaphragm, the sheets stuck to each other and were not aligned.

The present invention has been developed in view of the above-mentioned points, and its purpose is to simply load sheets of paper onto an elevating table in sequence from above, and then move the stacked sheets of paper by tilting the elevating table. The object of the present invention is to provide a high stack paper aligning device that is devised so that high stacks of paper can be stacked automatically and uniformly with the corners aligned by the vibration action of a diaphragm and the blowing action from a nozzle. .

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, in FIGS. 2 to 4, the symbol 1 indicates the machine frame as a whole, and this machine frame 1
consists of a bottom plate 2 and a plurality of rods (actually a total of 6) installed vertically at intervals on both left and right sides of the bottom plate

In addition, the left and right rear ends 4d and 4e of this ceiling frame body 4
Angles 5 and 6, which have guide grooves 5a and 6a vertically recessed in the opposing inner surfaces, are respectively fixed between the bottom plate 2 and both rear surfaces of the bottom plate 2. It has an approximately U-shaped cross section with the top and front sides open. 7 is a cover plate installed between the above-mentioned angles 5 and 6, and is actually a cover plate attached to the left and right columns 3...
A cover can also be attached to the outside of...

Next, reference numeral 8 denotes an elevating table mounted inside the machine frame 1 so as to be movable up and down.
A female screw 9 is provided at the center of the supporting portion 8a continuous to the rear surface side, and inside the female screw 9, there are provided the center portion of the rear side frame plate 4c of the top frame body 4 and the bottom plate 2.
A threaded rod 1 rotatably installed vertically between the bearing 10 of the
1 are inserted in a screwed state, and a pair of upper and lower guide rollers 12, 12 and 13, 13 are respectively attached to the upper and lower surfaces of both rear ends of the lifting table support section 8a.
However, each guide groove 5 of the left and right angles 5 and 6
a, 6a so as to be vertically movable. The entire lift table 8 configured in this manner is supported in a substantially cantilevered structure at three points at the support portion 8a by a threaded rod 11 and left and right guide rollers 12, 13, with the threaded rod 11 attached to the bottom plate. When rotated by a lifting motor 14 attached to the machine frame 1, the machine frame 1 moves up and down parallel to the machine frame 1. In the drawing, 11a is a bearing that supports the upper end of the screw rod 11, 11b is an interlocking gear attached to the screw rod 11, and 1
2a and 13a are bearings for the guide rollers 12 and 13, and 14a is a drive gear for the lifting motor 14.

Furthermore, in the figure, 15... are a plurality of positioning columns (actually 9 in total) vertically installed at intervals between the ceiling frame body 4 and the bottom plate 2 so as to surround the elevating passage of the elevating table 8. The paper P loaded onto the lifting table 8 is positioned by these positioning pillars 15 and the corners are aligned. Boards 4a and 4b
Three of them are attached to each of the rear frame plate 4c, but the number can be increased or decreased as desired. 16
. . . are diaphragms whose lower ends are rotatably supported on the positioning columns 15 . By vibrating the upper end side forward and backward (reciprocating) using the section as a fulcrum and sequentially lightly hitting the side edges of the sheets P loaded on the elevating table 8, the side surfaces of the sheets P can be uniformly aligned. 18,
Reference numerals 19 and 20 denote vibration motors attached to the left and right front and side surfaces of the paper machine frame 1, respectively. Eccentric rollers 17... are attached.

The structure of the diaphragm 16 will be explained in more detail based on the description in FIGS. 6 and 7. In the figure, 16
16b is a pressure plate attached to the upper rear surface of the diaphragm 16. Further, 16c is a swinging arm similarly attached to the back of the diaphragm 16, and the eccentric roller 17 has its left and right sides sandwiched between the pressure plate 16b and the pressure groove 16d formed at the tip of the swinging arm 16c. Therefore, when the eccentric roller 17 starts rotating, the entire diaphragm 16 vibrates finely in the horizontal direction in the drawing with the mounting shaft 16a at the lower end as a fulcrum, thereby aligning the sheets. There is a system in place to do this.

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. In addition, FIG. 5 shows the above-mentioned diaphragm 16...
. . , and the arrangement of the blower nozzles 22 . 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, and when the lifting table 8 comes into contact with these switches 23 and 24, the lifting motor 14 is turned off. By opening the power supply circuit, the lifting table 8 can be stopped at the upper limit point or the lower limit point. Also, 2
Reference numerals 5 and 25 are micro switches for paper alignment provided on the left and right upper portions of the elevating path of the elevating table 8.
5, the motor 14 rotates slightly in the forward direction, allowing the lifting table 8 to be lowered by a predetermined amount.

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 bottom surface, and the tilting means configured on this board 26 is
As shown in FIG. 2, FIG. 4, and FIG. 5, a pair of left and right tilting motors 27, 28, and this motor 2
Interlocking gears 29 and 30 that mesh with and rotate in conjunction with drive gears 27a and 28a of No. 7 and 28, and eccentric discs 32 and 33 that are eccentrically bolted to the sides of these interlocking gears 29 and 30 with bolts 31... These are left and right eccentric disks 32, 33.
The upper peripheral surface is configured to support support rollers 34 and 35 from below, which are rotatably and oscillatably attached to the left and right bottom surfaces of the bottom plate 2.

Further, 37 and 38 are gear shafts, 39 and 40 are bearings, and 43 is a flexible receiver that supports the center of the bottom plate 2 on the base plate 26. When tied together, they form a triangle. 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 addition to using the above-mentioned eccentric disk as the tilting means, for example, a plurality of hydraulic cylinders may be mounted on the base plate 26, and the entire machine frame 1 may be tilted by a piston rod that expands and contracts with these cylinders. , it may be possible to configure it so that it moves horizontally, but this selection is optional. In FIG. 2, 46 and 47 are provided on both sides of the machine frame 1 for loading, 48 and 49 are switch panels for operation, and 50 is for supplying air to the air blowing pipe 21. A blower, 51 is a control valve, and 52 and 53 are cocks.

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 is 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 side frame plate 4a of the ceiling frame body 4...
The positioning columns 15, which are also attached to the rear side 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 also prevent eccentricity. Since the diaphragm 16 vibrated by the roller 17 hits the side edges of these sheets of paper P, the corners of the sheets of paper P on the lifting table 8 are naturally aligned, and the air blown from the aforementioned blower nozzles 22... further promotes the above-mentioned alignment effect. still,
The vibration of the diaphragm 16 is performed by advancing and retracting the upper end using the shaft support 16a at the lower end as a fulcrum, so the diaphragm 16 only hits and vibrates the stacked upper layer of paper P. The diaphragm 16, in conjunction with the air blowing from the air blowing nozzle 22, can efficiently align the sheets P.

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.

As described above, the present invention includes the following steps: tilting the machine frame obliquely backward and loading sheets of paper one by one onto the tilted elevating table.
By simply repeating the action of lowering the lifting table by a certain width, the sheets are aligned according to the inclination of the machine frame, the vibration of the diaphragm that vibrates around the bottom end, and the air blowing from the nozzles. It is a type of paper that can be stacked high by hand, and the conventional method of stacking the paper in high stacks involves manually aligning the sheets one by one, or using a board or the like to strike the sides to align the sheets. In comparison, the work is much simpler and has the advantage that anyone can easily and accurately arrange a large number of sheets and stack them in high piles, contributing to labor savings in the work of arranging large piles.
