Medicine packing apparatus

摘要

A device for individually packaging medication comprises: a conveyance member for conveying a long packaging sheet, the packaging sheet being folded in two along the longitudinal direction thereof with a fold line disposed on the lower side; and a sealing member for sealing the packaging sheet. The sealing member is configured by integrating longitudinal and lateral sealing units. The longitudinal sealing unit being adapted to seal the edge of the packaging sheet, located on an opposite side of the fold line, and the lateral sealing unit being adapted to seal the packaging sheet at predetermined intervals in the longitudinal direction. The device further comprises: a support member for supporting the sealing member; and a control unit causing the sealing member to rotate idle while separating the longitudinal sealing unit from the packaging sheet and thereafter causing the longitudinal sealing unit to come into contact again with the packaging sheet.

主权项

1. A medicine packing apparatus, comprising:
a sheet feeder for feeding a packaging sheet, which is folded along a longitudinal direction of the packaging sheet and oriented so that the fold faces downwardly; a medicine supplier for supplying a medicine onto the packaging sheet from an upward direction; a pair of sealers for letting the packaging sheet between the sealers by rotating and for heat-sealing portions of the packaging sheet to pack the medicine in the packaging sheet, wherein each of the sealers comprises:
a longitudinal sealer for sealing an edge portion of the packaging sheet in the longitudinal direction, the edge portion being opposed to the fold of the packaging sheet, anda transverse sealer for sealing portions of the packaging sheet in a transverse direction of the packaging sheet so that the transversely sealed portions are spaced apart from each other by a predetermined width,wherein the longitudinal sealer and the transverse sealer are integrated in the sealer as one body; a support member for supporting at least one of the sealers so that at least the longitudinal sealer of said at least one of the sealers is attachable to and detachable from the packaging sheet; a conveyance roller provided downstream of a conveying direction from the pair of sealers, and for holding and conveying the packaging sheet; and a controller for controlling the rotations of the sealers and the conveyance roller, as well as the movement of said at least one of the sealers, wherein one of the pair of sealers is fixed to tilt on a fulcrum relative to the other of the pair of sealers, such that a first portion of the one of the pair of sealers is movable away from the other of the pair of sealers while a second portion of the one of the pair of sealers remains in contact with the other of the pair of sealers; wherein the controller adjusts the width between the transversely sealed portions by arranging at least the longitudinal sealer of said at least one of the sealers to rotate at a state detached from the packaging sheet; and, wherein the controller stops rotation of the conveyance roller when the at least one of the sealers are in the state detached from the packaging sheet.
