Title:
CHEMICAL BAG FEEDER
Document Type and Number:
WIPO Patent Application WO/2003/059744
Kind Code:
A1
Abstract:
A chemical bag feeder capable of feeding sufficient quantity of chemical bags while preventing injection from leaking out of the chemical bags even if the shape of a bucket is of general type, wherein one face of the chemical bag (3) storing injection is supported by a support member (5) excluding a tolerance for bending starting from an upper end opening part, the other face of the chemical bag (3) is guided by the guide part (26) of a vertically movable holding member (6) at least in a specified range exceeding the tolerance for bending starting from the upper end opening part, and the chemical bag (3) is pressed along the support member (5) and pressed by vertically moving a vertically movable pressing part (27) along the guide part (26), whereby, since the coefficient of friction of the pressing part (27) is made larger than that of the support member (5), only the chemical bag (3) can be raised, when the holding member (6) is raised, by holding between the guide part (26) and the pressing part (27).
