Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rod stacking device for blank sheets, printing books, and other laminated paper used in a printing machine, a bookbinding machine, etc. In addition to reducing the burden, the stacking paper is stacked with the outer peripheral end faces of the stacking paper properly aligned and set in the printing machine or bookbinding machine to improve the efficiency of printing work and bookbinding work. .

[0002]

2. Description of the Related Art Conventionally, a blank sheet or a printing book used in a printing machine or a bookbinding machine has been stacked on the upper surface of a table such as a pallet, and set in the apparatus together with the pallet. Then, in a printing machine or a bookbinding machine, the stacked paper such as the stacked white paper or the printed book is picked up one by one, and the printing work and the bookbinding work are performed while aligning them by a paper aligning mechanism or the like. In the work of stacking laminated paper used in these machines on sticks, an appropriate amount of the laminated paper stacked by a person is grasped by both hands and stacked on the upper surface of a pallet placed on a floor or the like.

[0003]

However, at the beginning of work when the amount of stacking paper on the pallet is small, the worker has to bend down and stack the laminated paper at a low position. On the contrary, when the stacking amount increased, heavier stacked papers were stacked at a high position with the waist and arms extended. In the work in such an irregular posture, there have been problems such as a worker injuring a lower back and an arm and a decrease in work efficiency.
In addition, stacking paper by hand is likely to cause misalignment of laminated paper, and if the misaligned state is set on the printing machine or bookbinding machine, paper jams and missing pages may occur, which may affect printing and bookbinding operations. It was Also, if the paper is uneven, it may collapse during transportation of the laminated paper, or the uneven edges may get stuck in the input port.
It may be difficult to set it on a printing machine or a binding machine.

In addition, when stacking sticks by manual work, an operator grips both ends of a certain amount of laminated paper and spins them by hand, and aligns them by inserting air between the papers. , It is possible to stack laminated paper with some alignment. However, it requires skill and time to arrange the finishes necessary for smooth work in a printing machine or a bookbinding machine, and also puts a heavy burden on the worker's body due to heavy labor.

The present invention is intended to solve the above-described problems, and sticks laminated paper such as a blank paper or a printing book used in a printing machine, a bookbinding machine, or the like, while roughly aligning the paper on two orthogonal sides. It is possible to stack and it is possible to perform this alignment work easily and efficiently. Further, the position of the paper placing table can be moved up and down according to the stacking amount of the laminated paper so that the operator can always stack the laminated paper at a fixed position. As a result, the worker can work in a comfortable posture, reduce the physical burden, and enable efficient work. In addition, by stacking the sheets in such an aligned state, it is possible to smoothly carry laminated paper and set it on a printing machine or a bookbinding machine, and at the same time, facilitate paper gripping and paper alignment work on these machines. In order to efficiently perform printing work and bookbinding work.

[0006]

In order to solve the above-mentioned problems, the present invention connects a stacking paper for stacking stacked sheets on the upper surface to a frame main body so that it can be moved up and down, and this frame main body Is rotatably supported by a tilting mechanism on at least one of the corners on the paper alignment side of the paper placing table to the base via a shaft support, and the corners on the paper aligning side of the laminated paper stacked on the paper placing table. Place the abutting parts of the laminated paper on the two sides that form the part,
A vibrator for applying vibration to the laminated paper and aligning the paper is provided so as to be in contact with the outer peripheral end surface of the laminated paper.

In the tilting mechanism of the frame main body, a plurality of shaft supporting portions of the frame main body are formed on a diagonal line of the paper placing table or at a position parallel to the diagonal lines, and the frame supporting body is driven by the driving force of the electric motor with the shaft supporting portions as fulcrums. May be tiltable.

In addition, the tilting mechanism of the frame main body supports a pair of cylinders provided in a rear surface of the frame main body on the rear surface of the frame main body, and at the same time, the lower end of the cylinder is pivotally supported on the base. The frame main body may be tiltable in the front-rear direction and the left-right direction via the shaft supporting portion.

Further, the abutting portion is movably arranged independently of the paper placing table on at least one of the two sides forming the corner of the paper placing table, and the abutting portion is attached to the paper placing table. It may be movable in the laminated paper direction.

Further, the vibrator is arranged on at least one of the two sides forming the corners of the paper placing table so as to be movable independently of the paper placing table, and the vibrator is laminated on the paper placing table. It may be movable in the laminated paper direction.

Further, a pressing body which is movable in the vertical direction is arranged on the frame main body so as to face the upper surface of the laminated paper, and the pressing body is moved up and down in accordance with the work of placing the laminated paper on the paper mounting table. Then, press the laminated paper of the part where the paper alignment is completed and fix it on the paper placing table, stack it on the top of this laminated paper, and then separate the laminated paper for the paper alignment and the laminated paper for which the paper alignment is completed Also good.

Further, the vibrator may be one that senses the placement of the laminated paper on the paper placing table by a sensor and applies vibration to the laminated paper for a certain period of time via the vibrator.

Further, the vibrator may use an electric vibration motor.

[0016]

The present invention is constructed as described above, and in order to stack stacked sheets such as blank sheets and printing books used in a printing machine, a bookbinding machine, etc. on the paper placing table while aligning them to some extent, first, The paper placing table connected to the frame body so as to be movable up and down is lifted and placed at a position where an operator who stacks the rods can easily perform the work. In this state, the vibrator for aligning the paper is arranged above the paper mounting table by the thickness of the laminated paper to be stacked. Next, by operating the tilting mechanism of the frame main body and inclining the frame main body via the shaft support, the corners of the paper tray on the paper alignment side are arranged below the other three corners. As described above, the paper placing table is tilted. Due to the inclination of the paper mounting table, it becomes possible to align the laminated paper on the abutting portion and the oscillator side which are arranged orthogonally.

When the inclination of the paper placing table is completed, an operator grasps an appropriate amount of laminated paper such as a white sheet for stacking a bar or a printing book with both hands and places it on the upper surface of the paper placing table. When the laminated paper is placed manually, the outer peripheral end surface of the laminated paper contacts the inner wall of the abutting portion and the vibrator. Further, when the laminated paper is placed, if the operator sags the laminated paper with both hands and introduces air between the papers, the friction resistance between the laminated papers is reduced and the next paper Alignment work becomes easier. However, since the aligning work is performed later at the abutting portion, it is not necessary to carefully perform the sabering work as in the conventional case.

Further, even when the laminated paper is placed on the slanted paper placing table, the two sides of the laminated paper aligned side hit the abutting portions arranged in the orthogonal direction, so that the laminated paper falls off from the placing table. There is nothing. After placing an appropriate amount of laminated paper in this way, the vibrator is operated to apply vibration to the laminated paper. Due to this vibration, the two orthogonal sides of the laminated paper are gradually aligned with each other.

When the paper alignment of the laminated paper is completed, the vibrator is stopped. And, by the height of stacked paper,
The paper placing table is lowered by the vertically moving means so that the outer peripheral end surface of the laminated paper to be placed next can come into contact with the vibrator. After this lowering, the operator next grasps the laminated paper to be aligned with an appropriate amount and places it on the top surface of the aligned laminated paper.
Then, by operating the vibrator again to give vibration to the laminated paper, the alignment work of the laminated paper placed this time can be performed well.

When this aligning work is completed, a series of operations such as stopping the vibrator, lowering the paper placing table, placing the next fixed amount of laminated paper, and operating the vibrator are repeated. By this operation, the laminated paper sheets are stacked on the upper surface of the paper placing table with a bar in a state where the two sides on the corner side of the paper placing table arranged below are aligned. After this stacking is completed, the tilting mechanism is operated to rotate the frame main body and restore the paper placing table to the horizontal state. And
The laminated paper stacked on the paper placing table is moved to a printing machine or a bookbinding machine, and the laminated paper is set in these devices.

As described above, by using the rod stacking apparatus of the present invention, it is possible to stack the stacked sheets of paper on the upper surface of the mounting table with high efficiency and in a properly aligned state. Further, since the paper placing table is lowered according to the stacking amount of the laminated paper, the operator can keep the stacking position of the laminated paper substantially constant. Therefore, the worker does not have to take an unreasonable posture such as bending his hips or raising his arms high, and it becomes possible to easily perform the stacking work of the laminated paper, the physical burden is reduced, and the work efficiency is reduced. Also improves. Also,
By stacking them in the aligned state, the stacking stability of stacking the laminated paper is also improved, and the stacking device can be smoothly transported to a printing machine, a bookbinding machine, or the like. Further, it is possible to favorably set the laminated paper on the printing machine or the bookbinding machine, prevent paper jams and missing pages, and efficiently perform the printing work and the bookbinding work.

As the tilting mechanism of the frame body, any mechanism may be used as long as the paper placing table can be tilted. For example, the tilting mechanism forms a plurality of shaft supporting parts of the frame main body on a diagonal line of the paper placing table or in a position parallel to the diagonal line, and forms the frame main body so that the frame main body can be tilted by the driving force of the electric motor with the shaft supporting parts as a fulcrum. . With this structure, the paper mounting table can be tilted in the direction of one corner on the paper alignment side, and the tilting mechanism can be formed at a low cost with a simple structure.

Further, in order to allow the paper placing table to be tilted not only at one corner side but also in any corner direction of the paper placing table, a pair of cylinders provided in a rear surface of the frame body in a V shape. To
A tilting mechanism is formed so as to be pivotally supported on the back surface of the frame main body and also the lower end of the cylinder is pivotally supported on the base, so that the frame main body can be tilted forward, backward, leftward, and rightward through the pivotal support of the frame main body. In such a tilting mechanism, for example, when the paper mounting table is tilted toward one of the corners on the back side, one of the pair of cylinders arranged in a V shape on the back surface of the frame body is positioned on the corner side to be positioned below. One cylinder is contracted largely and the other cylinder is contracted a small amount.

By this operation, the frame main body to which the paper placing table is connected pivots about the shaft supporting portion, and the paper placing table is tilted in the left-right direction in the direction of the largely contracted cylinder. Further, by contracting both of the cylinders, the paper placing table is attracted in the cylinder direction, so that it is also inclined in the rear direction. Due to the inclination in the left-right direction and the back direction, the paper mounting table is tilted in a state where one corner on the back side is arranged lower than the other three corners. In this way, by independently contracting the pair of cylinders and adjusting the amount of contraction, the paper placing table can be freely tilted in any corner direction, and the laminated paper can be arbitrarily You can arrange on two sides.

In addition, when stacking the laminated paper on a stick, it is usually preferable to place the laminated paper horizontally in the center of the paper placing table in consideration of the orientation when set in a printing machine or a bookbinding machine. However,
If the position of the abutting part that hits the laminated paper is fixed,
For small-sized laminated paper, laminated paper that is preferably placed vertically, and the like, it is unavoidable that the paper stacking table is bar-stacked not at the center but at a biased position. In order to eliminate this inconvenience, at least one of the abutting portions arranged on two sides of the laminated paper which intersect at right angles can be moved in the laminated paper direction independently of the paper placing table. Then, by moving the position of the abutting portion according to the size of the laminated paper and the mounting direction, the laminated paper can always be stacked on the center of the paper mounting table. Further, by appropriately moving the abutting portion, it is possible to stack the stacked sheets of paper not only at the center of the paper placing table but also at any position of the paper placing table.

The movable abutting portion may be arranged on one side surface of the paper placing table or on both sides thereof. By arranging them on both sides, it is possible to align the paper on either side of the laminated paper. Also, if the abutting part on the back side of the paper placing table can be moved, the laminated paper can be bar-stacked at any position in the front-back direction of the paper placing table according to the size of the laminated paper, the placing direction, and the purpose. You can do it.

As for the vibrator for vibrating the laminated paper, if it is arranged so as to be movable in the direction of the laminated paper in the same manner as the abutting part, the vibrator is always operated regardless of the size of the laminated paper and the mounting direction. It is possible to surely vibrate the laminated paper by bringing it into contact with the outer peripheral end surface of the laminated paper. Also, this vibrator may be formed only on one side of the side where the laminated paper is aligned, but if it is provided on two sides, the vibration is satisfactorily transmitted to the entire laminated paper, and even for large-sized laminated paper. You can arrange. Further, by disposing vibrators on both sides of the paper placing table and on three sides on the back side, the laminated paper can be aligned on either side of the paper placing table.

Further, on the upper surface of the laminated paper for which the paper alignment is completed,
Next, when the laminated paper for aligning the paper is placed, the laminated paper that has been carefully aligned may be disturbed by the wind pressure of the paper generated during the placement. In order to prevent this, a pressing body that can move in the vertical direction may be arranged so as to face the upper surface of the laminated paper. This pressing body moves up and down in accordance with the work of placing the laminated paper on the paper placing table, and presses the laminated paper at the portion where the paper alignment is completed to fix it on the paper placing table. It is possible to separate the laminated paper for which the paper alignment is completed and the laminated paper to be placed next, and it is possible to favorably prevent the disorder of the aligned laminated paper.

Further, it is preferable that the vibrator is not vibrated during the work of placing the laminated paper by the operator, and is vibrated when the stacking is completed and the papers are aligned. However, if the operator manually operates and stops the vibrator, the work efficiency is reduced. Therefore, if the vibrator senses the placement of the laminated paper on the paper placing table by the sensor and vibrates the laminated paper through the abutting portion for a certain period of time, and then stops the vibration, it is efficient. Work becomes possible.

Also, when the pressing body for pressing the laminated paper is pressed and released from the laminated paper by a manual operation or the like, there is a possibility that the work efficiency may be lowered and the work procedure may be complicated. Therefore, the pressing of the pressing body to the laminated paper is performed by detecting the end of the paper alignment work by the vibration of the vibrator with the sensor, and the release of the pressing to the laminated paper is performed by placing a new laminated paper on the paper mounting table. If the bar stacking device is formed so that the setting work is detected by the sensor, the paper alignment work can be performed efficiently.

Further, as the vibrator, any conventionally known one may be used, and for example, a ball member housed in the case may be eccentrically rotated by the introduction of air to generate vibration. In the case where the vibration is generated by the introduction of the air, it is easy to control the operation and stop of the vibrator, and even if the air leaks, the laminated paper is not affected at all. An electric vibration motor may be used as the vibrator, and the laminated paper can be satisfactorily vibrated.

By bringing the outer peripheral end face (24) of (2) into contact,
The vibration of (12) can be reliably transmitted to the laminated paper (2), and the laminated paper (2) abuts against the inner wall of the vibration transmission plate (25) while vibrating, so that the paper alignment effect is also enhanced. .

In order to stack stacked sheets of white paper, printing books, and other laminated paper used in a printing machine, a bookbinding machine, etc. by the stacking apparatus for stacked sheets of paper formed as described above, first, referring to FIGS. Drive the vertical movement mechanism (3), as shown in, and install the device (9).
Lower the paper table (1). Then, in order to facilitate the transportation of the laminated paper (2) and the setting in the printing machine or the bookbinding machine,
A pallet (27) having substantially the same size as the paper placing table (1) is placed on the upper surface of the paper placing table (1). Next, the paper placing table (1) is raised and the paper placing table (1) is arranged so as to face the vibration transmission plate (25) of the vibrator (12).

In this embodiment, laminated papers (2) having substantially the same size as the pallet (27) are stacked in bars, and the two sides of the laminated papers (2), which are orthogonal to each other on the left side and the back side, are directed toward the bar stacking device. Will be aligned with. Therefore, the corner portion (28) on the left rear surface of the paper placing table (1) is arranged below the other corner portions (30) (31) (32). To this end, one of the pair of cylinders (10) (11) arranged in a V shape on the back surface of the frame body (4) is greatly contracted in one cylinder (10) on the corner (28) side which is arranged below. ,
The other cylinder (11) is contracted by a small amount.
