Abstract

PURPOSE:To confirm the stop position of two or more trays using a single sensor by stopping the foremost tray of a group of trays just on the transport line at a certain specific point by a stopper, thereby stopping the other following trays, and by sensing the stop position of the trailing tray. CONSTITUTION:If this transport device is used, for ex., in an automatic mail treatment system, the device is installed behind a number of division boxes 6 of an automatic read-out division device in such an arrangement as to receive each group of mail 11 placed out of them, and a conveyor belt 8 is installed to place trays 10 upon in the number corresponding to the number of division boxes 6. A micro-switch 16 and a stopper 15 are arranged at the sides of this conveyor belt 8 in its close adjacency with a certain spacing. This switch 16 is installed in such an arrangement that each tray will front the division box 6 when a group of trays 10 have stopped and that the switch sense a dog 17 formed at the bottom of the trailing tray 10 when the size of accumulation has attained l. The automatic place-out mechanism for division box 6 is actuated at this time of sensing.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a paper sheet conveying device used in, for example, a FI1 automatic white goods processing system.

[Technical background of the invention and its problems]

The automatic mail processing system has one sorting machine, and this sorting JI
The IK is designed to sort and collect 114 pieces of mail based on their postal codes, and when the sorted and piled mail reaches a predetermined sound, it is automatically dispensed and transported to the next process by the mailbox itK. It has become so. The above-mentioned conveyance device is made up of a conveyance belt and a plurality of trays placed on the reversal belt to receive and receive the delivered mail.The above-mentioned trays ↑ move one pitch at a time from upstream to downstream and stop. While repeating this process, the trays are dispensed from the sorting boxes, but in order for the sorting boxes to start dispensing operations, it is necessary to confirm that the trays are stopped at the correct and current stop positions.

However, in the case of a normal sorting machine, the number of sections per section is 100
Since there are more than one tray, there is an inconvenience that if it is attempted to detect the stop position 1 of all the trays, the cost and CPU input required for this purpose will be enormous.

[Purpose of the invention]

The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to provide a conveying device for paper sheets that can confirm the stopping positions of a plurality of trays without having to detect all the stopping positions. This is what we are trying to provide.

[Summary of the invention]

In the present invention, the first tray of a group of toners placed on a conveyance path and passed through is stopped at a predetermined position by a stopper 4, so that the following trays are stopped continuously, and the ilk of this group of stopped trays is A detector detects the stopping position of the rear tray.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

1 in the figure is an automatic reading section molecule! The automatic reading and sorting device 1 has a supply section 3, a conveyance path 4, and a storage section 5 in one part of the main body 2, and a large number of parts arranged in multiple stages on the other side. Classification box 6... is cast. At the rear of the sorting device 1, a conveying device 7 for receiving and conveying the mail sent out from the sorting device t1 is arranged side by side as shown by the dotted line (in the drawing, for the sake of explanation, it is not practical). - is used for i11). As shown in Fig. 2, a plurality of conveyor belts 8 serving as a conveyor path running in the direction of the arrow are arranged in this feeder dF, and these conveyor belts 8

It is ejected by an ejection mechanism (not shown)! The 11th flight drama no is now under control. Further, a lift 12 for lowering the trays 10 is provided at one part of the conveyor belt 8, and the trays 10 lowered by this lift 11 are returned to the conveyor belt by JJK. 8 is conveyed to a return lift 14 provided on the other side. Incidentally, as shown in FIG. 3, the trays 10 on the conveyor belt 8 are conveyed in groups of a plurality of trays, for example, five trays. Stone 15 and micro switch 1# are placed with a distance of q. This microswitch 16 is connected to the group of trays 10 mentioned above.
When the trays 10 are stopped, each tray 10 is placed in the sorting box 9...
IIk when it faces correctly and its integrated size becomes J
Detection dock 11 formed on the bottom plate of the rear tray 100
It is designed to detect. At the time of this detection, the automatic dispensing mechanism of the sorting box 9 is activated.

The number of 4WAs for the above group of trays IO... is determined by the electrical combination of the accumulated sum of parts processing errors of the trays 10 and the difference in stop position detection d4 of the last tray 10.
・It is freely selected as long as it does not cause an obstacle due to the dispensing of the cord.
Granted in School 1 etc.! 11 pieces of mail 1l are supplied to the supply section J, where they are taken out one by one.Then, they are conveyed to the reading section 5 by the conveyance path 4, where 6 pieces of mail pieces 1 are taken out.
1 code mark is successively read and sorted into one of a plurality of sorting boxes 6... based on the reading result. On the other hand, the tray 10... of the transport Mi4e r is When the first tray 10 reaches the predetermined position and faces section 1!A6, the middle tray 15 is operated and stopped as shown in Figures 4 and 5. The trays 10 behind K then come into contact with the trays 10 in front and stop, as shown in Figure 4 ((
), when the micro-detection dock 1r of the acid trailing tray 10 is detected by the micro-switch 16, the automatic dispensing mechanism of the sorting box 6 operates to sort the mail 11 accumulated in a predetermined amount. Dispensed from S# and tray 10
It will be transferred to...

When this transfer is completed, the stone +15 is evacuated as shown in Figure 4 (B), and the conveyor belt 1 is run as shown in Figure 4 (C) to convey the tray 10 and transport it to a designated container. Then, it will be stopped again as shown in Fig. 4). By the way, when the trays 10 are stopped, if the intermediate tray 1o shifts from the normal stopping position and stops, the distance C from the front end to the rear end of the group of trays 10... will be -F*horizontal. size! , and the last tray 1
0 detection dock 18 is not detected by the microswitch IC. At this time, the dispensing mechanism of the sorting box 6 does not operate, and dispensing of the takumi saimono 11 is stopped.

As described above, the last tray 1 of the plurality of trays 10
By simply detecting the stop position of 0, the stop position of the intermediate tray 10 can be confirmed, so there is no need to detect each of the 41 trays 10 individually as in the past, and it is possible to check whether the stop position is correct or incorrect. can be determined.

Although the microswitch 16 is used as a detector in the above embodiment, a detector consisting of a photoelectric cell and a light beam passage hole may be used instead.

〔Effect of the invention〕

As explained above, the present invention stops the first tray of a group of trays placed on a conveyance path and conveyed at a predetermined position by using a stop analogy, thereby stopping the following trays, and stopping the following trays. Since the stop position of the tray at the rear of Rk is detected by the detector, it is possible to confirm the stop position of the intermediate tray without directly detecting it with the detector. Therefore, the stop positions of a plurality of trays can be recognized with four or more detectors, and the cost required for detection can be significantly reduced, as well as the number of input signals to the CPU can be reduced.
