  • Patent number: 7412809
    Abstract: A medicine envelope feeder capable of feeding a sufficient quantity of medicine envelopes while preventing injection medicine containers from leaking out of the medicine envelopes even if the shape of a bucket is of a general type. One face of the medicine envelope (3) is supported by a support member (5), excluding a tolerance for bending starting from an upper end opening part. The other face of the medicine envelope (3) is guided by a guide part (26) of a vertically movable holding member (6), and the medicine envelope (3) is folded along the support member (5) and pressed by lowering a vertically movable pressing part (27) along the guide part (26). Since the coefficient of friction of the pressing part (27) is larger than that of the support member 5, only the medicine envelope (3) can be raised while being held between the guide part (26) and the pressing part (27) when the holding member (6) is raised.

  • Patent number: 7322162
    Abstract: The bag top folder and labeler includes bottom and side conveyor assemblies for conveying a filled bag to extend between a pair of folder subassemblies wherein, with the bag top extending above the subassemblies, a second subassembly is operable to in cooperation with a first subassembly reversely fold the bag top relative to the second subassembly center folder and flap tuckers to form a generally Z-shaped bag top closure including ears extending outwardly in opposite directions and elevator mechanism for elevating the bag relative to the first subassembly to compensate for different densities of product in filled bags. Thereafter labeler mechanism applies labels to the folded bag top including to the ears, folds the ears downwardly along the end walls and wipes the labels to adhere to the ears and the bag front and rear end walls below the ears.
