Abstract

PURPOSE:To feed a very bulky article to be compressed, such as sliced-dried radish, dried wakame seaweed, etc., after its volume is satisfactorily reduced, by a method wherein a second step compression-pusher pushes the article out of a compression casing after a pusher member performs third step compression and a shutter is opened. CONSTITUTION:A shutter cylinder 2b is stretched and an article (w) to be compressed is placed in a compression casing 1. A first step compression cylinder 3b is stretched to compress the article (w) for the first step. A second step compression rodless cylinder 4d is stretched to compress the article (w) for the second step. A third step compression cylinder 5b is stretched to compress the article (w) for the third step. A pusher cylinder 4c is stretched to lower a pusher member 4b in two steps so that the article (w) after compressed for the third step is pushed into a feeding drum B through a lower opening 1a of the compression casing 1. The pusher cylinder 4c is immediately pulled back, and a cycle of compression operation finishes when the first step compression cylinder 3b, the second step compression rodless cylinder 4d and the third step compression cylinder 5b are pulled back.

In order to isolate the outside space from the inside space of the hopper, the first vertical compression plate 3a is provided with an upper sealing plate 3e and a side sealing plate 3f. The piston of the second-stage compression rodless cylinder 4d is designed to extend at a timing before and after the end of the extension action of the first compression cylinder 3b. and the extrusion member 4b are lowered together, and the horizontal compression plate 4a and the extrusion member 4b enter the compression casing internal space narrowed by the first vertical compression plate 3a substantially without any gap. Then, the material to be compressed W in the compression casing is compressed in a second stage. Note that the hole and hole C have a slit in the side wall to avoid interference with the piston table of the rodless cylinder 4d.

The piston of the third-stage compression cylinder 5b is designed to extend at a timing around the end of the extension operation of the second-stage compression rodless cylinder 4d. The internal space of the compression casing, which is narrowed in two stages by the vertical compression plate 3a and the horizontal compression plate 4a, is entered from both sides in the horizontal direction with virtually no gap, and the compressed object W housed in the compression casing 1 is It is designed to be compressed in three stages.
