DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a paper aligning device capable of stacking a large number of sheets of paper in a bar with their corners aligned.

For example, when printing on paper using a printing machine, it is necessary to set each printing paper with the center of the paper aligned in order to print at the same position on the paper under the same conditions). In order to cut paper to the same size, it is necessary to align at least two sides of each paper, but in the past, this paper alignment work was all done manually, which required a lot of effort and time, and was extremely inefficient. There were drawbacks such as the difficulty in aligning the paper evenly on the outside.

The present invention solves the above-mentioned drawbacks and provides a paper aligning device that can stack stacked papers in a bar with their corners automatically aligned evenly by simply stacking the stacked papers one after another in an appropriate manner (from above). The purpose is to

As shown in FIGS. 1 to 5, the base frame 1 includes a main frame 5 extending left and right with a predetermined negative angle and placed on the ground A, etc., and a main frame 5 extending left and right. a pillar 6 which is erected upward at the center of the tilting body 5 and supports the tilting body 2 in a freely tiltable manner;
A push-up part T that moves vertically at each tip of the main frame 5, pushes up both ends of the tilting body 2, and tilts around the support 6, and a tilting motor 8 that moves the push-up part 7 up and down are installed.

The tiltable support of the tilting body 2 by the pillar 6 includes, for example, a sphere 6a provided at the upper end of the pillar 6, and a spherical bearing 2a provided on the tilting body 2 so as to surround this sphere 6a. This is done by tilting the spherical 68 surface of the spherical bearing 2a. As shown in FIGS. 3 and 4, tiltable support of the tilting body 2 by the support column 6 is provided approximately in the vicinity of the center of the tilting body 2.

As shown in FIGS. 1 to 4 and 6, the push-up part 7 includes a rack 9 that is movable in the vertical direction, and a groove that is rotatably supported on the head of the rack 90 via a bottle 10. The roller 11 is movably engaged with plate-like protrusions 12 protruding from both ends of the vertical frame of the inclined body 2, which will be described later.

The rack 9 is disposed parallel to the left and right main frames 5, and is moved vertically by meshing with gears 15 and 16 attached to the tips of shafts 13 and 14, respectively, which are rotated by the tilting motor 8.

As shown in FIGS. 1 to 5, the inclined body 2 is composed of a horizontal frame 17 parallel to the main frame 5 extending left and right, and a plurality of vertical frames 18 substantially perpendicular to the horizontal frame 1T. The vertical frame 18 at both ends of this vertical frame 18.

18b is provided with a plate-shaped protrusion 12 that engages with the roller 11 of the push-up portion 7 described above. In addition, predetermined vertical frames 18 are formed with, for example, hexagonal columns 19a and 18b that engage with the guide rollers 19 of the lifting table 30, so that the lifting table 3 can be reliably guided even if a large number of papers are placed on the lifting table 3. It is formed like this.

A diaphragm 19 (-N in this embodiment for aligning the corners of the paper from both sides) 19 is installed above the inclined body 2 to align the paper. Each diaphragm 19 is in contact with the back surface, vibrates by the rotation of an eccentric roller (not shown) that is rotated by a vibration motor 20, and sequentially vibrates the side edge of the paper P loaded on the elevating table 3. The sides of the paper P are formed so as to be evenly aligned by being lightly beaten.

Furthermore, a lifting motor 21 for raising and lowering the lifting table 3 is installed at the upper end of the tilting body 2.

The rotation axis 22 of this Tanabata 21 is connected to one horizontal frame 1 of the tilting body 2.
At 7? There are nine lifting chains y23a, which will be described later.
Gear 24j25 that meshes directly with 73b, and the other horizontal frame 1
Elevating chain 2 via gears 26 and 27 pivotally supported by T
A gear 28 that meshes with 3c is provided.

In addition, with a predetermined vertical frame 18 of the inclined body 2, the elevating table 3
Limit switches 29 and 30 for upper and lower limits are installed on the elevating group path of the protrusion 3a, and when the protrusion 3a of the elevating table 3 comes into contact with these switches 29 and 30, the elevating member 21 The power supply circuit is opened, and the lifting table 3 is stopped at the upper limit point A or the lower limit point.

Furthermore, a micro switch 31 for paper alignment is installed above the lifting path of the lifting table 3.
When the stacked sheets of paper P come into contact with this switch 31, the elevating motor 21 rotates forward by a predetermined amount to lower the elevating table 3 by a predetermined amount. Therefore, the elevating table 3 is lowered by a predetermined amount TL every time sheets P are stacked on the elevating table 3, and this operation is repeated until the above-mentioned lower limit point.

Further, above the tilting body 2, a blowing pipe 33 having a blowing nozzle 32 is installed toward the direction of the lifting table 3, and the sheets P stacked on the lifting table 3 receive air ejected from the blowing nozzle 32. As a result, air enters each sheet of paper P and adhesion due to static electricity is prevented, and the diaphragm 19
Paper alignment work can proceed smoothly.

The elevating table 3 has elevating chains 23a to 23'e fixed at positions (three points in this embodiment) where it can be maintained horizontally, and the elevating chains 23a to 23'e are raised and lowered by the elevating motor 21. The lifting table 3 is moved up and down. At this time, in order to ensure that the lifting table 3 is raised and lowered, the side surface of the lifting table 3 is in contact with the vertical frame 1B, and a guide roller 19 having a groove that engages with, for example, a hexagonal column 18 is provided in an opposing state. There is.

Next, the operation of this invention will be explained.

To stack sheets, first drive the tilting motor 8, push up the left and right push-up parts 7 as shown in FIGS. 2 to 4, and tilt the tilting body 2 around the support 6. .

Here, since the support column 6 is positioned at a predetermined height near the center of the tilting body 2, the range of movement of the tilting body 2 can be minimized during tilting, and reliable and smooth operation can be achieved. In particular, the plate-shaped protrusion 1 that comes into contact with the roller 11 of the push-up part 7
Since the amount of movement of roller 2 can be suppressed to a minimum, the tilting operation can be performed smoothly while reliably engaging the roller 11.

Next, the lifting motor 21 is driven, and the lifting chain 23a is
23c is wound up and moved to the upper limit position where the upper limit switch 29 is activated. At this time, lift table 3
is raised smoothly and evenly by the guide row 219 and the vertical frame 18 that comes into contact with the lifting table 3. Therefore, as shown in FIGS. 3A and 3B, the portion of the elevating table 3 where the corners of the sheets P are aligned is located at the lowest inclined position.

Next, an appropriate number of sheets of paper P are stacked one after another on the elevating table 3, but each time the paper P is stacked, the microswitch 31 is pressed by the paper P, so the elevating table 3 is lowered by a predetermined amount, and the corner of the paper P is just above the diaphragm. 19 in an optimal state, and the corners are automatically aligned very effectively. At this time, the air ejected from the blower nozzle 32 is
This can prevent the paper P from adhering due to static electricity, etc.
Furthermore, paper alignment work can be performed effectively.

The above-mentioned operation is repeated one after another until the protruding piece 3a of the lifting table 3 comes into contact with the lower limit switch 30, and is stopped when the lifting table 3 descends to the lowest limit, thereby completing the stacking of the sheets P.

, After completing the work on L-J, turn the tilting motor 8 again.
, the push-up part 7 is lowered, the tilting body 2 is returned to its original horizontal state, and the paper P stacked on each pallet is taken out using a shifter lift (not shown) or the like from the front. work is completed.

In the above-described series of operations, when the number of sheets P to be aligned is small, the tilting morph 8 and the lifting motor 21 are operated simultaneously even when the lifting table 3 does not reach the lower limit switch 30. It is also possible to return the elevating table 3 and the tilting body 2 to one lift mounting position.

Also, during actual use, paper P may be damaged.

In order to prevent entry into the apparatus, a decorative plate (not shown) or the like is attached between the vertical and horizontal frames 17 and 18 of the inclined body 2 and on the base frame 1 and the like.

As described above, according to the present invention, by simply tilting the tilting body and loading appropriate sheets of paper onto the tilted elevating table,
The vibrating action of the diaphragm automatically stacks the bars, dramatically improving efficiency compared to the conventional method that relied on human power, and it also has extremely excellent effects such as allowing anyone to align the sheets accurately. be.
