There is a difference in that it does. However, the same is true in that identification information 29 of the second content 25 is acquired to generate and transmit confirmation information.

In step S93, the classification unit 50 classifies the plastic bag 35 into the good product 35c and the defective product 35d by using the identified identification information. That is, the classification unit 50 classifies the plastic bag 35 manufactured according to the confirmation information received from the confirmation unit 40 into a good product 35c and a defective product 35d. The goods 35c of the plastic bag 35 are automatically collected in accordance with the movement of the movable worktable 10 to the goods storage box 60 installed close to the end in the traveling direction of the movable worktable 10. The defective part 35d of the plastic bag 35 is collected by the sorting unit 50 into the defective item collection box 70 disposed on one side of the distal end of the movable work bench 10.

Meanwhile, the defective items 35d collected in the defective item collection box 70 are collected and opened, and then performed again from step S81.

In the first embodiment, an example in which the confirmation unit 40 is installed in the loading unit 20 and the confirmation unit 40 in the second embodiment has been described is not limited thereto. That is, the verification unit 40 may be any place where it is possible to check the identification information 29 of the second contents 25 sequentially input. For example, the second contents 25 may be installed at an upper portion of the movable work platform 10 into which the second contents 25 are inserted.

Alternatively, the identification unit 40 may be installed together with the loading unit 20 and the classification unit 50 to double check the identification information 29 of the second contents 25.

In the first and second embodiments, the classifying section 50 discloses an example of directly classifying the defective article 35d, but is not limited thereto. For example, the classification unit 50 may output a warning sound or display a warning light when the defective product 35d moves according to the confirmation information received from the confirming unit 40 so that the operator may easily select the defective product 35d. .

In addition, the embodiments disclosed in the specification and the drawings are only presented as specific examples for clarity and are not intended to limit the scope of the present invention. It will be apparent to those skilled in the art that other modifications based on the technical idea of the present invention are possible in addition to the embodiments disclosed herein.
