Packaging device

Abstract

Provided is a packaging device capable of conveying packaging paper while maintaining the tension thereof but without applying an excessive load thereto. A packaging device according to the present invention is a packaging device configured to package a medical drug loaded from a loading hopper. The packaging device is configured to supply the medical drug into a packaging strip through an opening provided by folding the packaging strip in half and to close the packaging strip by sealing the opening. The packaging device includes a packaging-strip holder around which the packaging strip is wrapped and held; a plurality of rollers around which a portion of the packaging strip that is drawn from the packaging-strip holder is wrapped; a feed roller configured to repeatedly pull out the packaging strip in units of a length for a single package; and a tension adjustment mechanism provided on a downstream side relative to the packaging-strip holder and on an upstream side relative to the feed roller, the tension adjustment mechanism being configured to keep a tension of the packaging strip that is pulled out by a feed roller constant. The tension adjustment mechanism includes a mobile roller and an urging member, the mobile roller being supported such that a rotation axis of the mobile roller is allowed to move in a direction orthogonal to the rotation axis, the urging member pulling the mobile roller toward a reference position with a predetermined force. The mobile roller moves upon detection of the packaging strip receiving a tensile force greater than or equal to the predetermined force.
