SEALING DEVICE AND MEDICINE PACKAGING APPARATUS
First Claim
1. A sealing device comprising:
- a pair of frames A, B each including a heating part attached thereto such that each of the heating parts are rotatable around a predetermined rotating shaft, the heating part generating heat by energization; and
an engaging mechanism configured to couple the frames A, B such that the frames A, B are not separated in a direction that widens a gap between the heating parts,wherein when the frames A, B are coupled by the engaging mechanism, a thermally bondable sheet is fusion-bonded while being passed through a clearance formed between the heating parts,wherein the engaging mechanism includes an engager and a receptor,wherein the engager is provided in the frame A and includes;
a first rotator rotatable around a first shaft; and
a second rotator rotatable around the first shaft in concomitance with a rotation of the first rotator, the second rotator eccentrically rotatable relative to the first shaft,wherein the receptor is provided in the frame B and the second rotator is engageable to the receptor,wherein the engaging mechanism is switchable to a first engagement state where the second rotator is engageable to the receptor in a position P1 by the rotation of the first rotator of the engager and to a second engagement state where the second rotator is pulled to a position P2 closer to the frame A than the position P1 engaging the receptor.

Abstract
A sealing device and a medicine packaging apparatus that includes the sealing device, wherein an engaging mechanism for coupling frames has good operability and the frames can firmly engage each other. The sealing device (10) can couple roller frames (20a, 20b) by an engaging mechanism (40) to integrate the roller frames. The engaging mechanism (40) has an engager (45) and a receptor (46) formed of a recess or the like. The engager includes a manipulation lever (50) and an engaging lever (51). The engager (45) is provided in the roller frame (20a), while the receptor (46) is provided in the roller frame (20b). When the manipulation lever (50) is pushed and pivoted toward the roller frame (20b), the engaging mechanism (40) can integrate the roller frames (20a, 20b). When the manipulation lever (50) is pulled and pivoted toward a front portion, the engaging mechanism can release the engagement caused by the engaging mechanism (40) to allow the roller frames (20a, 20b) to be separable from each other.
