Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sheet material handling device that sorts and accumulates sheet materials such as copy paper, transfer paper, and recording paper discharged from image forming apparatuses such as copying machines, printing machines, and recording equipment. be.

Conventionally, this type of apparatus includes a plurality of trays arranged only on one side of a conveyance path for sheet materials carried out from an image forming apparatus, and - sorts the sheet materials conveyed along the conveyance path into each tray; configured to accumulate. Therefore, to increase the number of trays, two such units can be used.
It was customary to arrange two units side by side and distribute the sheet materials to these units for classification and accumulation. Placing two units side by side in this way increases the overall size of the machine and therefore requires a large amount of floor space;
Furthermore, the classification operation of sheet materials becomes complicated.

In order to improve the shortcomings of such sheet material handling devices, a plurality of trays are arranged on both sides of the conveyance path for the sheet material carried out from the image forming apparatus, and the sheet materials carried out from the image forming apparatus are transported along the conveyance path. A sheet material handling device has been developed that transports sheets along a transport path and sorts and accumulates them on trays arranged on the left and right sides of a transport path. In such a sheet material handling device, if the sheet materials accumulated on the left tray are loaded onto the 78th Atsuzo, the sheet materials accumulated on the right tray will be shoved face down. In order to load either the left or right tray in either the 7-eighth-up or face-down format, a reversing unit is provided to reverse the sheet material being delivered from the image forming apparatus, and the sheet material is loaded in either the left or right tray. It is necessary to invert the sheet material when loading it into the tray.

Also, a deflector for guiding the sheet material conveyed along the conveyance path toward the tray in order to load the sheet material onto one of the trays in the rows of left and right trays, and the relative position of this deflector and the tray. However, the moving unit in the above-mentioned sheet material handling device is, for example, sequentially larger than the left tray, and if there is no reversing unit, the moving unit is
If there is a reversing unit, the configuration is such that the reversing unit is then used to load onto the right tray, but this requires time to switch from left to right, and the moving unit only needs to be loaded once. You will have to go back and fill the trays one by one starting from the bottom tray. However, as the machine becomes faster, this margin is no longer available, and it becomes necessary to interrupt paper feeding.

The present invention aims to provide a sheet material handling device that eliminates such drawbacks, and is intended to obtain information on the number of sheet materials to be sorted from an image forming device such as a copying machine, and to determine the number of sheet materials to be sorted. To provide a sheet material handling device in which when the number of sheets exceeds the number of trays on one side, a reversing unit is turned on and off to first put the sheet materials alternately into the left and right trays. In other words, the moving unit is moved after accommodating two sheets. For example, when making 20 copies, the tray is moved to one on both the left and right.
At the time of 5, the process proceeds while appropriately using the 5-copy reversing unit for each of the left and right trays, and the remaining sheets are processed without using the 1-sheet reversing unit.

Hereinafter, the present invention will be described in detail with reference to the drawings.

The illustrated embodiment uses an electrophotographic copying device capable of double-sided copying as an image forming apparatus. shows a sheet material handling device according to the present invention,
The copying apparatus M may be of a well-known type, and after copying an image onto a sheet material fed through a sheet material inlet 1, carries out the copied sheet material from an outlet 2. The duplex unit B transfers the sheet material carried out from the outlet 2 to the sheet material handling device C.
A conveyance system 3 that conveys the sheet material up to the point where the sheet material is conveyed, a reversing device knit 4 provided in the middle of the conveyance system that inverts the sheet material, and a reversing device 4 that inverts the sheet material carried out from the conveyance port and then feeds the sheet material into the copying machine again. It has a double-sided recording system 5 for performing Ryomaki Kama.

A discharge port 26 for discharging the sheet material to the outside and a discharge port 27 for transmitting the sheet material to the device C are arranged at the sheet material discharge port of the double-sided unit) H. , a deflector 8 are provided.

The sheet material carried out from the carry-out port 2 of the image recording apparatus A passes through the double-sided conveyance system 3) and is sent to the discharge port 56 and discharged outside by the deflector 8, or is discharged to the outside through the discharge port 7. and is thereby sent to device C.

When the sheet material is reversed and sent, the sheet material is introduced into the reversal slot 10 by the deflation (5) lid 9 provided in the middle of the conveyance system 3, and
Thereafter, it is returned to the conveyance system 3 by the rollers 11. When double-sided recording is performed, the sheet material recorded on the first side is introduced into the image forming apparatus A again through the double-sided recording system 5, recorded on the second side, and then passed through the above-mentioned conveyance system 3. Sent.

The sheet material handling device IC has one conveyance path 15 for conveying the sheet material that is conveyed upward by the above-mentioned discharge roller 7, and is conveyed by an id 12, a conveyance roller 13, and an id 14; comprising rows 16, 17 of trays arranged in parallel on both sides for receiving sheet materials, and deflectors selectively guiding the sheet materials conveyed along the transport path to the rows 16 or 17 of trays on either side thereof. There is.

The conveying path 15 includes a row of driving rollers 18 and driven rollers 19, and conveys the sheet material upward.

In the illustrated example, the rows of trays 16, 17 are trays 16a arranged vertically next to each other.

16b,...16n and 17ae17b,...
...Constructed by 1711. Although not shown in the figure (6), the deflector deflects the sheet material carried by the conveyance path 15 to I9.
It is configured to deflect to the right or left at the desired tray. Thus, the sheet materials are deflected to the left or right and are sequentially sorted and stored in the trays 16m, 16b, . . . 16n, and 17m, 17b, = 17mK.

In the case of the duplex unit 30, the tray 16 is
m + 16 b + =・”・i 6 When entering m, face down, tray 17m, 17b,・
...When entering 17n, it will be face-up.

Conversely, when entering the reversing slot 10 of the duplex unit B, passing through the rollers 11 and exiting to the normal path, the tray 16 m +
16 b + =” 16 m is stored face up, tray 17 m, 17 b, = 1
It is stored face down at 7m. Therefore, by using one vertical conveyance path and inserting an inverted arm, it is possible to double the classification accumulation and obtain the desired shape on both sides.

According to the present invention, when the information on the number of copies is obtained from the electrophotographic copying device and the number of copies exceeds the number of trays 1 and 17, sheet materials are placed alternately in the left and right trays 16 and 17. , the deflector and the mobile unit are controlled. In this case, when the sheet material is placed in a tray on either the left or right side, the sheet material is sent via the reversing unit 4.

The moving unit is moved after two sheets of sheet material have been placed in the left and right trays. For example, when the left and right trays are 150 o'clock for 20 copies, the reversing unit for 5 copies each is placed in the left and right trays. Proceed by using it as appropriate, and the remaining sheets can be advanced without using the single-sheet reversing unit. In this way, sheet materials can be sorted and accumulated at high speed without requiring time for returning the moving unit once.
