Description

[Detailed explanation of the idea] The present invention relates to a sorter in a copying machine, a printing machine, etc.

2. Description of the Related Art Sorters or collators conventionally installed in copying machines, printing machines, and the like have complicated mechanisms and are therefore expensive.

The present invention has been developed in consideration of the above-mentioned problems, and aims to simplify the control means for the paper conveyance device and indexer (distributor) of the sorter, thereby providing a compact and inexpensive sorter.

The structure will be explained below based on the embodiment shown in the drawings.

In the figure, 1 is a main body of a copying machine or a printing machine, etc., 2 is a discharge roll for discharging copied or printed paper, and conveyance guides 4 and 5 of a sorter 3 according to the present invention are opposed to this.

Reference numerals 6 and 7 are conveyance rolls and driven rolls that convey the paper inserted into the conveyance guides 4 and 5.

Reference numeral 8 denotes a conveyance belt for conveying the paper along each bin opening of the tray 9, and a conveyance auxiliary member 11 in which a large number of spheres 10 are rotatably embedded and provided along the front edge of the ceiling plate of each bin opening. are in contact with each other, and the paper is conveyed while being sandwiched between the conveyance belt 8 and the conveyance auxiliary member 11.

Reference numeral 12 denotes an indexer, which is provided so as to move along each bin opening of the tray 8, and feeds the paper conveyed by the conveyor belt 8 into each bin.

This indexer 12 is constructed as shown in FIGS. 2 and 3, and includes a back plate 13, a front plate 14, and a deflecting plate 15 fixed to the back plate 13 for deflecting the paper into the bin. A conveyor belt 8 passes between the back plate 13 and the front plate 14.

The back plate 13 and the front plate 14 each have a guide bell extending upward.} 16. 17 are attached, and these bells}16.17 are attached to the rolls 18. 19 is involved.

The indexer 12 is stretched downward by a spring member 20 via a wire 21.

Roll 1 involving guide bell) - 16 and 17
8 and 19 are connected to a rotary solenoid 23 via a one-way clutch 22, and this rotary solenoid 23 connects the indexer 1 by a distance corresponding to one opening of the bottle.
It is designed to wind up 2.

This winding timing is determined by installing a lamp 23 and a photocell 24 through holes penetrating appropriate parts of all the bins, and receiving a signal that the paper has entered the bin. When the indexer 12 is released, the indexer 12 is returned to its original position by the tensile force of the spring member 23.

There are various ways to determine the timing for releasing the clutch 22, but each bottle is provided with a protrusion for driving the microswitch in a tiltable manner, and the operator raises the predetermined protrusion to engage the microswitch of the indexer 12. to be done by.

If one of these protrusions is not raised, it will not be possible to start.

In addition, in the unlikely event that after a certain period of time has passed after paper has been placed in one bin, there is no signal indicating that paper is in the next bin, the sorter's conveyance function is temporarily stopped, and at the same time, the paper conveyance guide 4 , 5 are flipped upwards using a solenoid as shown by chain lines 4' and 5' in Figure 1.

In this way, the conveyance guides 4, 5 themselves function in place of an overflow bin.

If a paper jam occurs in the vertical conveyance system using the conveyor belt 8, the sorter is opened along the chain line 25 in the figure using the bin 24 as a fulcrum, and the jammed paper is discharged.

Note that the mechanism for winding up the indexer 12 is not limited to the rotary solenoid, but may be a structure that converts reciprocating motion into rotational motion using a retractable solenoid 26 as shown in FIG.

Further, the conveyance auxiliary member 11 may be a roller array instead of a ball array, or may be a fixed friction material as long as it has a small friction coefficient.

In the above structure, the paper discharged from the main body 1 of the copying machine or the like passes through the conveyance guides 4 and 5 of the sorter 2, is sent by the conveyance roll 6 and the driven roll 7, is turned over, and is transferred to the conveyance belt 8.
From there, it is sandwiched between the conveyor belt 8 and the conveyance auxiliary member 11, and is conveyed downward by the frictional force of the conveyor belt 8,
The indexer 12 distributes the data to each bin.

The paper conveyed by the conveyor belt 8 passes between the back plate 13 and the front plate 14 of the indexer 12, so that the paper is transported by the guide bell attached to the indexer 12}16.1
7 and between the back plate 13 and the front plate 14.
At step 5, the liquid is smoothly poured into each bottle.

Also, at this time, since the conveyance belt 8 passes between the back plate 13 and the front plate 14, the conveyance auxiliary member 11 that is in rolling contact with the conveyance belt 8 only interferes with the front plate 14 of the indexer 12. By making the front plate 14 thin, it does not interfere with paper conveyance at all.

The present invention is as described above, and the paper is conveyed by sandwiching the paper in contact with the conveying auxiliary member 11, which has a small coefficient of friction and is made of a rolling member, etc., provided along the front edge of the ceiling plate of each bin opening. It has a conveyor belt 8, a back plate 13 having a deflection plate 15 for selectively feeding paper into each of a plurality of bins, and a front plate 14 opposite to the back plate 13. The belt 8 passes through the indexer 12, and the indexer 12 is provided to be movable back and forth along each of the bins, and the indexer 12 is provided with a spring member 20 that biases the indexer 12 in one direction of movement. Since the guide bells H6 and 17 that move the inserter and the hook 12 against the spring member 20 are connected, and the intermittent drive device is connected to the rolls 18 and 19 that wind the guide bells H6 and 17, the paper of the sorter is moved. The conveyance device and the control means for the indexer 12 can be simplified, thereby making it possible to obtain a compact and inexpensive sorter.

According to the present invention, there is provided a spring member 20 that urges the indexer 12 in one direction of its movement, and a guide bell l that moves the indexer 12 against the spring member 20.
-16 and 17 are connected, and a drive device is connected via a one-way clutch 22 to the roll 18.19 that winds up the guide belt 16.17.
The driving device for driving the indexer 12 only needs to be a driving device for moving the indexer 12 in one direction, and the driving device can be simplified.
