Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a stack of sheets re-loaded from a sheet feeding stand to a sheet aligning machine.
It is used in the technical field of high stacking paper aligning device that aligns two sides and one corner with a bar, and specifically, when stacking a stack of sheets on a paper tray or a aligner, The present invention relates to a paper transposing device capable of reversing the sides of a sheet and transposing.

[Conventional technology]

When transferring a stack of paper from the paper feed tray to the paper aligner, if you want to move the paper stack straight forward without turning it over, hold the stack of paper and move it sideways in the direction of the paper aligner. They are transposed by sliding on a transfer plate that is installed between the paper table and the paper aligner.

On the other hand, if you want to reverse the front and back of the stack of paper
It may be directly inverted by hand, or the inventor of the present application may first apply for a patent.
A reversing device as disclosed in the reversing method and reversing mechanism for a sheet aligning device proposed in 61-215352 (Japanese Patent Laid-Open No. 63-71053) is used.

In the above-mentioned conventional reversing device, a reversing shaft (spreading roller) is horizontally installed in a cantilever state on a transfer plate provided between a paper feed table and a paper aligning machine so as to be orthogonal to the paper feeding direction, and The reversing shaft is configured to rotate in the direction opposite to the paper feeding direction. In order to reverse the surface of the sheet bundle, first, an appropriate sheet bundle is slid and moved from the paper feed table to the delivery plate. After that, the rear end of the sheet bundle is manually lifted to be wound around the reversing shaft, and then the rear end side is guided so as to be pressed downward. , The mechanism is such that it can be fed on the paper aligning machine side in an inverted state by sliding on the transfer board.

[Problems to be Solved by the Invention]

As described above, according to the above-described conventional reversing device, it is possible to extremely easily and easily transfer the sheet bundle to be transferred from the sheet feeding table to the sheet aligning machine.
It is possible to reverse without causing problems such as wrinkles and folds.However, this reversing device, when transposing a stack of paper from the paper feed tray to the paper aligner, uses a lift for straight-line transposition. It is necessary to slide and move the stack of sheets of paper that rises up to the position of the transfer board. Also, when reversing and transposing, the stack of sheets of paper that also rises up on the lift should be moved from the top of the paper feed tray each time It is necessary to slide the reversing shaft laterally to the position of the above-mentioned bridging plate and to wind the rear end side of the moved sheet bundle at the time of reversing, which is a troublesome task for the worker. There is also a problem that a large amount of exercise is required and it takes a long time to carry out a single transshipment, which greatly increases the time effect on the entire paper alignment work (bar stacking work).

Further, in the case of the above-mentioned conventional reversing device, regardless of the size of the paper to be reversed, the paper must always be slid to a position where the rear end can be wound around the reversing shaft.
In the case of a paper having a large paper width, there have been many problems that the reversing work is time-consuming, the work time is delayed more than necessary, and wrinkles or folds occur in the paper.

Further, in the conventional paper transposing device, a stack of sheets is stacked on a paper plate, and the stack is stacked on a lift in a plurality of stages.
The stacks of paper that are lifted up by the lift are transferred in sequence, but in addition to the above-mentioned paper reversal work, the used paper plate is taken out from the upper surface of the paper feed tray each time it is transferred. This work was very troublesome, and the above-mentioned reversing work was made more and more complicated.

Therefore, the technical problem of the present invention is that the sheet bundle is turned over to the sheet aligning machine very easily from the top of the sheet feeding table without sliding the sheet bundle to the position of the transfer plate. It is possible to re-load it with and to arrange the paper board easily.

[Means for Solving the Problems]

Means taken in the present invention to solve the above technical problems are as follows.

A stack of paper stacks is stacked on the lift of the paper feed stand in multiple stages, and the paper stack pushed up by the lift is slid on the transfer plate and moved to one side of the paper feed stand. In a high stacking paper aligning device configured to be stacked on a side of a paper aligning machine arranged side by side and stack the stacked stacks of paper so that two sides and one corner are aligned, (1) The separating roller should be configured to rotate in the direction opposite to the paper feeding direction so as to be orthogonal to the paper feeding direction.

(2) A guide screw shaft, which can be rotated forward and backward by a motor, is installed in parallel on one side of the paper feed table, and the root of the separation roller is mounted on a mounting table configured to reciprocate according to the rotation of the guide screw shaft. Support the ends in a cantilevered state.

(3) On the other side of the paper feed table, a board trimming machine that takes in the above-mentioned paper placing board is installed in parallel, and between the board trimming machine and the paper feeding tray,
A lift configured to provide a guide roller for feeding the paper placing plate taken out from the paper feed table into the inside of the plate removing machine, and to be lowered by one step each time the fed paper placing plate is stacked on the plate removing machine. Be provided.

[Action]

 The above means operate as follows.

The element of (1) above is such that when a sheet bundle is placed on a separating roller that rotates in a direction opposite to the paper feeding direction,
While the stack of paper can be moved straight in the direction of the paper aligner, the rear end of the stack of paper (the end side opposite to the feeding direction) can be lifted up and wound around the sorting roller to move the stack of paper to the front and back. It is possible to turn it over and feed it in the direction of the paper aligner.

When it is desired to move the sheet bundle straight without inverting the sheet bundle, the element of the above (2) rotates the guide screw shaft in one direction by the motor to move the separating roller to the straight transposing position on the sheet aligner side, and then , If the leading end side of the sheet bundle is passed under this sorting roller or placed on it, the sheet bundle can be moved straight and reloaded from the transfer board to the sheet aligner side. If you want to transship
Similarly, the guide screw shaft is rotated in the other direction by the motor to move the separating roller to the reverse position to the side opposite to the paper aligning machine, and then the trailing end side of the sheet bundle is wound around this separating roller to form the sheet bundle. It can be fed and moved in the direction of the paper aligning machine according to the rotation of the separating roller so that it can be reloaded. Therefore, in the case of reverse transposition, it is not necessary to move the stack of sheets to the position of the transfer plate, This makes it possible to easily transfer the rollers by simply moving the rollers with the guide screw shaft.

The element of the above (3) is capable of feeding the empty paper placing plate, which has undergone the transposition of the sheet bundle, to the adjacent plate removing machine side by using the guide roller, and placing the taken-up paper placing plate. Since the lift lifts one step each time one paper stack is stacked, it is possible to pick up used paper stacks one by one on top.

As described above, the technical problems described above can be solved by the above means, and the problems of the conventional technology can be solved.

In the case of a straight line, a separating roller described below is used. In the case of reversing on the left side in FIG. 4, that is, out of the plane of the paper P and not disturbing, the separating roller is also moved to the reversing position in the right direction in FIG. .

Next, the construction of the paper transposing apparatus of the present invention used in the high stacking paper aligning apparatus configured as described above will be described with reference to the drawings.

In the figure, reference numeral 30 denotes a separating roller (reversing roller) horizontally installed in a cantilever state on the upper surface of the paper feed table 1 so as to be orthogonal to the paper feeding direction, which is a main member of the paper transposing apparatus of the present invention. The roller 30 is configured to be rotated by a motor, which will be described later, in the direction opposite to the paper feeding direction, that is, in the counterclockwise rotation direction in FIGS.

Further specifically explaining the configuration of the above-mentioned paper transposing device,
In FIG. 3, 30T is a supporting base that supports the above-mentioned separating roller 30 rotatably in a cantilever manner, and 30M is a drive gear 3
