DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to, for example, a copying machine for copying and a printing machine and a printing machine for printing. The present invention relates to a bin structure of a sorter that sequentially distributes a plurality of bins in a stack.

[0002]

2. Description of the Related Art In a conventional sorter, as shown in FIG. 5, a plurality of bins 1 are moved up and down at predetermined intervals and tilted so that the front side in the paper entry direction is higher than the front side. The moving frame 2 is also raised and lowered by raising and lowering the bin 1 that has received the paper by a raising and lowering mechanism (not shown) provided on the fixed frame 3 side so as to raise and lower the entire plurality of bins 1. are doing.

[0003] When the printed sheets are sorted by such a sorter, each bin 1 is inclined so that the front side in the paper entering direction is higher than the front side, and therefore the bins 1 receive the sheets. When the sheet is received, the sheet rises along the inclination of the bin 1 and is received, so that the leading edge of the received sheet slides on the printing surface of the already discharged sheet and is received.

[0004] However, at the time of sorting, even if the printing ink is not sufficiently dried, it is possible to shift the bin 1 and distribute the paper to each bin 1 in order to obtain a drying time before receiving the next paper. Yes, the next paper is accepted, and the printing inks do not stain each other.

[0005] However, in the case of non-sorting, that is, when the printed paper is not distributed but is received only in the uppermost bin 1a, the drying time of the printing ink cannot be sufficiently obtained. 1a, there is a problem that the leading edge of the received paper is rubbed with the undried printing ink of the already discharged paper, and the papers are stained with each other.

As a means for solving this, as shown in FIG. 6, a horizontal bin 1b dedicated to non-sorting is mounted on the uppermost portion of the sorter, and a fixed horizontal bin 1b dedicated to receiving non-distributed paper is mounted. Conceivable.

In this case, the sheets are not stained with each other due to the sliding of the sheets as described above. However, when such a fixed bin 1b is provided, the sheet receiving side of the sorter becomes bulky as shown by a virtual line at the time of sorting. For example, if a document feeder or other service mechanism is configured to protrude above the sorter at the upper side of the paper discharge side of a printing machine or a copying machine, the above-mentioned horizontal fixed bin 1b impedes this. There is a problem.

[0008]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems, and provides a bin dedicated to non-sorting of a sorter to prevent mutual contamination of paper due to sliding even when paper is accumulated. An object of the present invention is to provide a bin structure of a sorter in which a paper receiving side does not become bulky even if a bin dedicated to non-sorting is provided.

[0009]

SUMMARY OF THE INVENTION According to the present invention, a plurality of bins, which are tilted so that the front side in the paper entering direction is higher than the front side thereof and are held at predetermined intervals on the moving frame, are arranged along the fixed frame. A sorter for distributing and storing processed paper in each bin by sequentially moving the processed paper upward or downward, and a non-distribution bin for receiving processed paper that is not to be distributed in proximity to the top of the plurality of bins. Is pivotally attached to the moving frame so that the sheet receiving side can be tilted from the horizontal position to the lower position, and biased in the tilting direction, based on the movement of the moving frame. When the non-distribution bin is opposed to the sheet receiving position, a holding member for holding the non-distribution bin in a horizontal position at the position against the urging force is provided on the fixed frame side. And wherein the Rukoto.

[0010]

In the bin structure of the sorter according to the present invention, when all the bins are lowered to the lowermost position and the uppermost non-distribution bin is opposed to the sheet discharge position during non-sorting, the non-distribution bin contacts the holding member of the fixed frame. The paper ejected from the paper ejection position is received in the non-distribution bin without the leading edge sliding on the surface of the already ejected paper. In addition, when sorting, when the bin for sorting is opposed to the discharge position, the bin for non-distribution is tilted so that the paper receiving side is lower than the pivot point at the leading end side in the paper entry direction as a fulcrum. The upper part on the paper discharge side of the sorter becomes bulky.

[0011]

As described above, according to the present invention, in the case of non-sorting, the discharged paper is received in a horizontal non-distribution bin, so that even if the printing ink on the paper is not dried, the received paper can be received. Can be prevented from slipping on the undried printing ink of the already discharged paper, and the papers are not stained with each other, and the quality of the processed paper can be improved.

When the non-distribution bin is not used, the bin is inclined in the same manner as the inclined bin for sorting.
For example, even if a document feeder or other service mechanism is configured to protrude above the sorter at the upper side of the paper discharge side of a printing machine or a copier, the presence of the above-mentioned non-distribution bins hinders this. Is prevented, and the space can be used effectively.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to the drawings. The drawings show a bin structure of a sorter. In FIGS. 1 and 2, a sorter 10 is a processing machine 1 such as a copying machine or a printing machine.
1, an endless belt 14 is stretched between a discharge port 12 of the processing machine 11 and a receiving port 13 of the sorter 10, and the paper discharged from the processing machine 11 is sorted by the sorter 10. Leading to.

The sorter 10 holds the plurality of sorting bins 15 on the moving frame 16 while maintaining a predetermined interval vertically and inclining so that the front side in the paper entering direction is higher than the front side. The bins 15 facing the receiving ports 13 of the sorting bins 15 sequentially move the fixed frame 17 upward or downward by an elevating mechanism (not shown), so that the moving frame 16 also multiplies the fixed frame 17 and moves along the fixed frame 17. Move.

The upper part of the moving frame 16 described above,
A non-distribution bin 18 is pivotally attached to a shaft 19 at a position close to the uppermost bin 15 at the end on the front side in the sheet entry direction.

As shown in FIG. 3, the non-distribution bin 18 is provided with a plurality of abutting pieces 20 on the paper receiving side, and a plurality of abutting pieces 21 at the rear end. An extended extension plate 22 is continuously provided, and standing pieces 23 are provided on both sides of the center so as to be able to receive a sheet.

At the left and right sides of the rear end of the above-mentioned bottle 18, the vertical pieces 2 are provided.
4 and 24 are connected in series, and the above-mentioned shaft 1
9 is inserted. Further, a bottle 25 is planted on the side of the front end of the above-mentioned hanging piece 24, and a locking piece 27 is formed on a fixing plate 26 fixed to the inner side of the moving frame 16 described above. A spring 28 is stretched between the locking piece 27 and the locking piece 27 to urge the receiving side of the non-distribution bin 18 downward. A stop pin 29 interlocking with the vertical movement of the moving frame 16 is normally received in an inclined shape.

When the above-mentioned non-distribution bin 18 is at the paper receiving position, the holding members 30, 30 for holding the non-distribution bin 18 in a horizontal position are fixed to the fixing frame 17 by screws. By contacting a contact piece 31 continuously provided on the side edge of the non-distribution bin 18 with a contact piece 31 provided continuously to 30,
The posture is maintained.

At the time of non-sorting of the sorter constructed as described above, as shown in FIG. 1, the moving frame 16 is moved to the lowermost position and the sorting bins 15 are moved to the lowermost position. The ear 32 abuts against the contact piece 31 of the holding member 30 of the fixed frame 17, and the non-distribution bin 18 is held in a horizontal position against the spring 28 and faces the paper receiving port 13.

In this state, the paper discharged from the paper discharge port 12 of the processing machine 11 is guided to the sorter side through the endless belt 14 and is received from the receiving port 13 into the non-distribution bin 18. At this time, the leading edge of the sheet is not rubbed against the bottom of the non-distribution bin 18 at the time of receiving the sheet.
Even if the non-distribution bin 18 has already received, for example, sheets of paper that have not been dried with the printing ink, the sheets are not stained with the printing ink.

When the sorters are sorted, as shown in FIG. 4, when the sorting bins 15 are moved to the sorting position, that is, when the moving frame 16 is moved up to the sorting position, the sorting bins 15 are moved up. The non-distribution bin 18 is tilted downward by the spring 28 and abuts against the stop pin 29 to maintain the tilted posture.

For this reason, even if the moving frame 16 moves to the uppermost position, the bulk of the non-distribution bin 18 on the receiving side is reduced, and the document feeder 3 mounted above the non-distributing bin 18 is mounted thereon.
Even if 3 protrudes above the sorter 10, it does not come into contact with it.

The configuration of the present invention is not limited to the configuration of the embodiment. For example, a non-distribution bin 18
The extension plate 22 may be configured to be compact by rotating or sliding the extension plate 22 around the shaft 19 toward the upper surface of the non-distribution bin.
