Abstract:
A continuous bag supply device, in a continuous-filling packaging system, for converting a movement of empty bag supplied intermittently in a plurality of rows into a continuous movement of a single row, wherein said device is provided with:a bag holding member conveying device in which a plurality of bag holding members disposed at equal intervals are moved in one direction along a ring-form track that is on a horizontal plane and that has a pair of parallel sections, so that said bag holding members are moved intermittently a certain distance on a first side of said parallel sections and moved continuously at a constant speed on a second side of said parallel sections, said certain distance being equal to an attachment pitch of said plurality of bag holding members multiplied by a number of bags supplied simultaneously by a bag supply device; and said bag supply device which is on said first side of said parallel sections simultaneously supplies empty bags to said plurality of bag holding members so that one empty bag is supplied to each of said plurality of bag holding member; and wherein empty bags are supplied in a plurality of rows to said plurality of bag holding members, which are stopped, by said bag supply device on said first side of said parallel sections, and said empty bags are successively extincted and supplied from said plurality of bag holding members, which are continuously moving, on said second side of said parallel sections; and a rotary type transfer device which has a plurality of transfer means which hold said empty bags by vacuum suction and are disposed at equal intervals is provided on said second side of said parallel sections, and said rotary type transfer device continuously receives empty bags from said bag holding members by said transfer means which continuously rotate and continuously supply said empty bags to a device used in a next process.
