Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] In the present invention, cut sheets sequentially fed along a cut sheet supply line are respectively placed on the left and right sides of the cut sheet supply line and in parallel with this line. The present invention relates to a cut sheet sorting device for selectively sorting and feeding one of the left row, the right row, and the cut sheet supply row.

[Prior Art] For example, as a cut sheet allocating device for allocating cut sheets sequentially fed along a cut sheet supply row to three rows or two rows and sequentially feeding the cut sheets, the cuts that are sequentially fed are conventionally used. It has been proposed to sort and feed the paper in three rows or two rows by one carrier or a conveyor belt.

However, in such a conventional apparatus, the first cut sheet to be supplied is placed on a carrier or a conveyor belt, moved to a predetermined row and fed, and then the second cut sheet is fed out. This carrier or conveyor belt must be returned to the original cut sheet supply line before it arrives, so that the next cut sheet is placed in the sorting position until the carrier or conveyor belt is returned to the cut sheet supply line that supplies the cut sheets. The feed speed of the cut sheet had to be limited so that it would not reach the limit, and there was an inevitable drawback that the processing speed could not be increased.

[Problems to be Solved by the Invention] The present invention eliminates the above-mentioned drawbacks of the conventional cut sheet allocating apparatus, and can significantly improve the feed rate of the cut sheet and improve the work efficiency. The purpose is to provide.

[Means for Solving the Problems] In order to achieve the above-mentioned object, a cut sheet distribution device according to the present invention is configured so that cut sheets sequentially fed along a cut sheet supply line In a cut sheet allocating device that selectively distributes and feeds to the left and right rows or the cut paper supply row, which are respectively positioned on the left and right in parallel to the cut paper supply row, is supported by a guide shaft. A cut that is guided parallel to a plane including the cut sheet supply row, the left row, and the right row and movably in a direction orthogonal to each row, and is fed along the cut paper supply row. A first carrier and a second carrier each having an opening for receiving a paper and having a floor part which is controlled by an operating means and which can be opened and closed so as to receive and discharge a cut sheet; and the first carrier. Always above The first carrier is held at a position aligned with the left row, but at a predetermined time, the first carrier is moved from a position aligned with the left row to a position aligned with the cut sheet supply row via first transmission means. , The first drive means for reciprocating so as to return to the left column after receiving the cut sheet, and the second carrier are always held at a position aligned with the right column, but at a predetermined time. And moving the second carrier from a position aligned with the right row to a position aligned with the cut sheet supply row via the second transmission means, and returning to the right row after receiving the cut sheet. It is characterized by comprising a second driving means for reciprocating.

[Operation] Since the cut sheet sorting apparatus of the present invention is configured as described above, when the cut sheets to be fed are to be fed along the cut sheet feed line, If the first and second carriers are held in the positions aligned with the left and right columns, respectively, the cut sheet is fed along the cut sheet supply column without being interfered by any carrier. Can continue.

When the cut sheets are distributed to the left row and fed, the first drive motor is first driven to move the first carrier from the left row to a position aligned with the cut sheet supply row, and the cut sheet is passed through the opening. After receiving the sheet, the drive motor is driven again to return to the position aligned with the left column, the operating means is activated to open the floor, and the cut sheet received inside the carrier is discharged to the left. It can be fed along the line.

If the next cut sheet is distributed to the right row and is fed, while the first carrier is returned to the left row after receiving the cut sheet at the position of the cut sheet supply row, Then, the second carrier is moved by the second drive motor to a position where it is aligned with the cut sheet supply row to receive the cut sheet, and after receiving the cut sheet, it is returned to the position where it is aligned with the right row by the drive motor again. After that, the actuating means can be actuated to open the floor portion to eject the cut sheet and feed it along the right row.

If the cut paper is sorted into the left row or the right row and the next cut paper is continuously fed along the cut paper supply row, the first or second carrier cuts the cut paper. Discharge the paper and keep it in the left or right row with the floor closed, or hold it in the left or right row with the floor open, It may be closed when it is moved to the cut sheet supply line to receive the cut sheets.
As a result, the cut sheet supply line is not interfered by the first and second carriers, and the cut sheet continues to be fed along the cut sheet supply line.

As described above, when only the conventional carrier or conveyor belt is used, the carrier or conveyor belt is moved to distribute one sheet of cut paper to a desired row and then fed, and then the carrier or conveyor belt. According to the present invention, the feeding speed of the cut sheet must be limited so that the next cut sheet does not reach the sorting position until the sheet is returned to the position aligned with the cut sheet supply line. Such a limitation of the feed speed is not necessary at all, and the desired carrier is fed to the next desired row immediately after the delivery of one sheet of the cut sheet to start feeding. Since it is possible to perform the movement for aligning in one line, it is possible to significantly improve the feed speed of the cut sheet.

Further, even if the cut sheet is supplied at a high speed, the respective movements of the carrier itself may be relatively slow.

If you want to feed cut sheets to different rows alternately,
The carrier need only be moved to the receiving position once every three sheets.

Therefore, for example, when the cut sheet is sent once every 3 seconds, it only needs to be done once every 9 seconds, so when the cut sheet is received, it will take time to calm down even if it bounces in the carrier. You can do it.
