BEST MODE FOR CARRYING OUT THE INVENTION As a package to be sorted by the apparatus of the present invention, a package obtained by sealing and packaging a fluid content using a packaging material such as a film can be mentioned. The present invention is very efficiently applied to body sorting, and the fluid content is a granular or liquid material. A package obtained by seal packaging is prepared by a so-called four-side seal in which two pieces of packaging material are abutted and sealed around four sides, a so-called three-way seal in which one piece of packaging material is folded in two and the other three sides are sealed. In general, they are prepared as strip-shaped packages that are integrally connected in the vertical and / or horizontal direction, and are cut as they are at a certain number of lengths into products. More generally, however, the strip-shaped package of the connected oxygen absorber is cut off individually with a cutter or the like to form a product. Individually separated packages may be sealed in containers that can be stored in a fixed number as they are to be used as product packages for sale.However, it is necessary to remove defective products and move them to the place where they are sealed in the containers. Therefore, they are conveyed by a belt conveyor or the like, inspected to detect an abnormality in the internal capacity or a defective seal, the defective products are removed, and the non-defective products are sealed in a storage container while counting the quantity. In the present invention, the transport is performed using a transporter such as a chain conveyor that can be transported while hanging with a holder such as a clip. In the course of transport, the package that is transported while hanging is inspected to detect an abnormal content or a defective seal, defective products are removed, and non-defective products are enclosed in a storage container while counting the number. However, the partition plate and the movable plate are used in the present invention in order to efficiently select defective products of the package and to sort non-defective packages for each packaging unit as a product.

Hereinafter, the present invention will be described with reference to the drawings. FIG.
