Meanwhile, the upper surface of the carrier 180 passing through the second scanner 150 is scanned on the tray 184, and the scan information thereof is input to the main server and stored.

At this time, if there is no information about the item scanned by the second scanner 150 , the normal state is obtained, and when the information about the item is scanned, the item is classified as an abnormally classified item.

That is, the tray 184 of the carrier 180 passing through the second scanner 150 is rotated in one direction by the fixed discharge guide block 160a provided in the transport conveyor 100 at the rear of the second scanner 150, As the product is tilted, the articles existing on the tray 184 are all discharged to the abnormal classification discharge chute 130a behind the second scanner 150 and are classified as abnormally classified articles.

And, after the classification of the abnormally classified article, the tray 184 of the carrier 180, which was inclined in one direction by the position guide block 170, is erected in the correct position, and in this state, by the transfer conveyor 100 It moves repeatedly while drawing an infinite orbit.

In addition, the abnormally classified goods classified as abnormal are collected by the operator and re-inserted into the transfer conveyor 100 or manually sorted.

On the other hand, when the normally classified article is classified and the accommodated member is in a full state, the full load detection sensor 141 provided in the lower part of the corresponding discharge chute 130 detects it, and the corresponding discharge chute 130 by its detection signal. ), the article is not discharged and classified, but passes through the corresponding discharge chute 130 as it is, and is classified as an abnormally classified article in the abnormally classified discharge chute 130a at the rear of the second scanner 150.

And, when the full detection sensor is operated, the main server can automatically block the discharge of the product to the corresponding discharge chute 130, or the worker presses the unused switch provided in the corresponding discharge chute 130 to semi-automatically discharge the product can be blocked with

In this state, the full accommodating member is separated from the cradle 140 and the opened entrance is bundled, and then a bar code label of the area is attached to the discharging conveyor 190 under the transfer conveyor 100 to the accommodating member in the full state. is put in and discharged.

At this time, if the accommodating member discharged by the discharge conveyor 190 is not transported for reasons such as jamming and remains in a stopped state for a certain period of time, the accommodating member detection sensor 191 provided in the discharge conveyor 190 detects it Accordingly, the main server discharges the accommodating member by continuously operating the discharging conveyor 190 of the operated accommodating member detection sensor 191 rear (the rear end side of the transfer conveyor 100) to discharge the accommodating member detection sensor 191 ) The discharge conveyor 190 in the front can be maintained while preventing the accumulation of the receiving member by stopping the operation.

Although the present invention has been described in detail through specific examples, this is intended to describe the present invention in detail, and the present invention is not limited thereto, and by those of ordinary skill in the art within the technical spirit of the present invention. It is clear that the modification or improvement is possible.
