Description

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

Generally, when printing on paper using a printing machine,
In order to print at the same position on the paper under the same conditions, it is necessary to set the corners of each printing paper so that they are aligned.Also, to cut paper of different sizes to the same size, at least two sides of each paper must be set. It is necessary to align the paper, but in the past, all of this paper alignment work was done manually, which required a lot of effort and time, was extremely inefficient, and it was difficult to align the paper evenly. .

Therefore, for example, as in the paper aligning machine disclosed in Japanese Patent Publication No. 50-15175, an elevating table that can be moved up and down can be tilted at a predetermined angle, and
Conventionally, a vibrating device has been devised that automatically aligns the corners of the sheets by attaching a vibration means and placing the sheets one after another on an elevating table.

On the other hand, when sheets to be aligned are stacked in a so-called "high stack", their weight becomes quite large. Therefore, after completing the paper alignment work, it is necessary to use a transport means such as a forklift in order to move the stacked sheets to a distant location.

However, since the above-mentioned conventional paper alignment device is configured to push up the elevating table from below, various devices or parts must be placed below the elevating table, which makes it difficult to use when using a forklift. There is a risk that these devices, components, etc. may be damaged. In addition, in order to efficiently align paper in a "heavy stack" state where the weight increases, it is preferable to have a configuration that allows paper to be stacked as high as possible. Since the paper is moved in a horizontal direction, it is impossible to increase the stacking height of the sheets to a large extent. For these reasons, conventionally it has not been possible to realize a paper alignment device that automatically aligns large-sized sheets.

This invention was made in view of the above circumstances, and it is possible to increase the stacking height of paper as much as possible when performing the paper alignment work of large-sized paper with a simple configuration, and to To provide a high stack paper aligning device that can freely use a conveying means such as a forklift when moving paper.

An embodiment of the present invention will be described below with reference to the drawings.

As shown in FIGS. 1 to 4, the high stack paper aligning device according to the present invention includes a base frame 1, a tilting body 2 supported by the base frame 1, and tiltingly movable with respect to the base frame 1. , a lifting table 3 mounted to be movable up and down along the inclined body 2, and a vibrating ruler plate (hereinafter abbreviated as a vibrating plate) 4 provided on the upper part of the inclined body 2 for aligning paper. , and a lifting chain 23 which is a hanging member that suspends the lifting table 3.

It has a tilting motor 8 that moves the push-up part 7 up and down.

The inclined body 2 is above the base frame 1 and extends in the left-right direction so as to correspond to the base frame 1. and,
The tiltable support of the tilting body 2 by the pillar 6 is as follows:
For example, this is accomplished by tilting the surface of the sphere 6a by a sphere 6a provided at the upper end of the support column 6 and a sphere bearing 2a provided on the oblique body 2 so as to surround the sphere 6a. Further, tiltable support of the tilting body 2 by the support column 6 is performed at approximately the center of the tilting body 2, as shown in FIGS. 3 and 4.

Furthermore, as shown in FIGS. 1 to 4 and 6, the push-up part 7 has a rack 9 that is movable in the vertical direction, and a head of the rack 9 that is rotatably supported via a pin 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 meshes with gears 15 and 16 attached to the tips of shafts 13 and 14, respectively, which are rotated by a tilting motor 8, so that the rack 9 can be raised and lowered in the vertical direction. be moved. As shown in FIGS. 1 to 5, the inclined body 2 includes a horizontal frame 17 parallel to the main frame 5 extending left and right, and a plurality of vertical frames 1 substantially perpendicular to the horizontal frame 17.
8, and the rollers 1 of the push-up part 7 mentioned above are mounted on the vertical frames 18a and 18b at both ends of the vertical frame 18.
A plate-like protrusion 12 that engages with 1 is provided.

On the inner surface of the inclined body 2, an elevating table 3 for stacking sheets is disposed so as to be movable up and down. Predetermined vertical frames 18 are formed with, for example, hexagonal columns 18a and 18b that engage with the guide rollers 19 of the lifting table 3, so that even if a large number of papers are placed on the lifting table 3, the lifting table 3 can be reliably moved. It is designed to guide you.

Above the inclined body 2, a diaphragm 4 (a pair in this embodiment for aligning the corners of the paper from both sides) 4 is installed to align the paper. Each diaphragm 4 is in contact with the back surface, vibrates by the rotation of an eccentric roller (not shown) rotated by a vibration motor 20, and sequentially lightly touches the side edge of the paper stacked on the lifting table 3. It is attached so that the sides of the paper are evenly aligned by hitting it.

Further, a lifting motor 21 serving as a drive device for raising and lowering the lifting table 3 is attached to the upper end of the tilting body 2. Rotating shaft 22 of this motor 21
is arranged along one horizontal frame 17 of the inclined body 2, and this rotating shaft 22 has gears 24, 25 that directly mesh with lifting chains 23a, 23b as hanging members, which will be described later, and gears 24, 25 on the other side. A gear 28 is provided which meshes with a lifting chain 23c as a hanging member via gears 26 and 27 which are pivotally supported by the horizontal frame 17. In addition, limit switches 29 and 30 for upper and lower limits are installed on a predetermined vertical frame 18 of the tilting body 2 on the elevating path of the protruding piece 3a of the elevating table 3, and the protruding piece 3a of the elevating table 3 When it comes into contact with the switches 29 and 30, the lifting motor 21
The power supply circuit is opened, and the lifting table 3 is stopped at the upper limit point or the lower limit point. Furthermore, a micro switch 31 for aligning paper is installed above the elevating path of the elevating table 3, which functions as a paper height detecting means. When the sheets stacked on the lifting table 3 come into contact with the switch 31, the lifting motor 21 rotates forward by a predetermined amount to lower the lifting table 3 by a predetermined amount. Therefore, the lifting table 3
is lowered by a predetermined amount each time sheets are stacked on the lifting table 3, and this operation is repeated until the above-mentioned lower limit point is reached.

Further, above the tilting body 2, a blowing pipe having a blowing nozzle 32 is installed toward the direction of the lifting table 3, and the sheets stacked on the lifting table 3 receive the air ejected from the blowing nozzle 32.
Air enters each sheet of paper to prevent adhesion due to static electricity, and the paper alignment operation by the diaphragm 4 can proceed smoothly.

The elevating table 3 has elevating chains 23a to 23c, which are hanging members, fixed at positions (three points in this embodiment) where the elevating table 3 can be maintained horizontally, and the elevating chains 23a to 23c are raised and lowered by the elevating motor 21. The lifting table 3 is moved up and down by the. At this time, in order to ensure the lifting and lowering of the lifting table 3, the sides of the lifting table 3 are provided with vertical frames 18.
For example, the hexagonal column 18
A guide roller 19 is provided which has a groove that engages a.

Next, the operation of this embodiment will be explained.

To stack paper high, first turn the tilting motor 8.
is driven to push up the left and right push-up parts 7 as shown in FIGS. 2 to 4, and the tilting body 2 is tilted about the pillar 6. Here, the tilting body 2 is attached to the base frame 1 so as to be tiltable at its center, and is tilted by being pushed up a predetermined amount by the push-up portion 7 at both ends. Therefore, the situation is similar to applying the principle of a lever, and even though the tilting body 2 has a considerable weight, it can be tilted with as little driving force as possible.

Next, the lifting motor 21 is driven to wind up the lifting chains 23a to 23c and move them to the upper limit position where the upper limit switch 29 is activated. At this time, the elevating table 3 is smoothly and evenly raised by the guide rollers 19 and the vertical frame 18 that comes into contact with the elevating table 3. Therefore, the lifting table 3
As shown in FIGS. 2 to 4, the portion where the corners of the paper are aligned is at the lowest inclined position.

Next, an appropriate number of sheets of paper are stacked one after another on the elevating table 3. Each time the paper is piled up, the micro switch 31 is pressed by the paper, so the elevating table 3 is lowered by a predetermined amount, and the vibration plate 4 in an optimal state, and the corners are automatically aligned very effectively. At this time, the air ejected from the blower nozzle 32 enters between the sheets, preventing the sheets from adhering to each other due to static electricity, etc., and furthermore, the sheet alignment work is performed effectively.

The above-mentioned operations are sequentially repeated until the protruding piece 3a of the lifting table 3 comes into contact with the lower limit switch 30, and when the lifting table 3 descends to the lowest limit, it is stopped and the stacking of sheets is completed.

After the above operations are completed, the tilting motor 8 is driven again, the push-up part 7 is lowered, the tilting body 2 is returned to its original horizontal state, and the pallet is lifted from the front using a forklift (not shown) or the like. All you have to do is take out the high pile of paper each time and the whole job is completed.

By the way, when using a forklift to remove paper from a conventional paper alignment device,
Generally, there is a concern that the tip of the fork of the forklift or other parts may come into contact with any part of the paper aligning device, causing damage. However, as is clear from the above explanation,
In the paper aligning device according to the present invention, the lifting table 3 is suspended by the lifting chains 23a to 23c, and no equipment is provided below, so there are almost no accidents caused by contact with forklifts, etc. There is no need to consider anything. Furthermore, the paper is not moved horizontally by hand as in conventional devices, but is moved by a forklift or the like after the paper alignment work is completed, so that the paper stacked on the lifting table 3 is The stacking height can be made sufficiently high, making it possible to carry out efficient movement.

In addition, in the above series of operations, when there are few sheets to be arranged, the lower limit switch 30
Even when the lifting table 3 does not reach the forklift position, the tilting motor 8 and the lifting motor 21 can be operated simultaneously to return the lifting table 3 and the tilting body 2 to the forklift mounting position.

In addition, in actual use, in order to prevent paper from being damaged or entering the apparatus, a decorative board (not shown) or the like should be placed between the vertical and horizontal frames 17 and 18 of the tilting body 2 and between the base frame 1 and the like. is installed.

As described above, according to the present invention, a tilting body is tiltably attached to the center of the base frame having push-up parts at both ends, and a lifting table that can be raised and lowered is disposed on the inner surface of the tilting body, This includes hanging members, drive devices,
Since the configuration combines diaphragms, it is possible to increase the stacking height of paper as much as possible when aligning a large stack of paper, and it is also possible to use a fork when moving the stacked paper. This has the advantage that transport means such as lifts can be used freely.
