Abstract

A drug filling machine having a plurality of feeders containing a plurality of different kinds of drugs. A plurality of the drugs are discharged from one or some of the feeders into a vial. A sealing unit is provided for sealing the mouth of the vial with a transparent sheet. The sealing unit includes a sheet presser for pushing the transparent sheet into the mouth of the vial to form a sealing sheet having a tray-shaped section, a cutter for cutting the transparent sheet into a predetermined shape, and a heater for fusing the transparent sheet to the top end of the vial to seal the mouth of the vial. A method of inspecting the drugs contained in the vial includes preparing the transparent sheet a sealing portion for covering the mouth of the vial, and a printed portion that protrudes outwardly of the mouth of the vial. After inspecting the drugs in the vial, the printed portion is separated from the sealing portion, and a cap is secured on the mouth of the vial.

Claims

1. A drug filling machine comprising:

a printing unit for selecting an envelope of a desired size from among a plurality of envelopes of different sizes, and printing necessary information on the selected envelope;

an envelope opening unit for receiving the envelope selected and printed by said printing unit, and opening a mouth of the envelope by applying a suction force to the envelope; and

a device for delivering at least one vial into the envelope through the open mouth of the envelope,

wherein said envelope opening unit comprises;

a pivot table for receiving the envelope and pivoting between a first inclined position and a second inclined position;

a vacuum arm movable relative to said pivot table; and

a vacuum device in communication with said pivot table and said vacuum arm to provide a vacuum to said pivot table and said vacuum arm.

2. The drug filling machine as claimed in claim 1, wherein said pivot table is adapted to receive the selected and printed envelope from said printing unit in the first inclined position.

3. The drug filling machine as claimed in claim 2, wherein said pivot table is adapted to hold the envelope on a support surface of said pivot table by a suction force supplied by said vacuum device.

4. The drug filling machine as claimed in claim 3, wherein a tip portion of said vacuum arm is located adjacent the support surface of said pivot table while in the second inclined position such that a suction force can be applied to the envelope held on said pivot table, and a mouth of the envelope can be opened by moving said vacuum arm away from said pivot table to receive at least one vial from the vial delivery device.

5. The drug filling machine as claimed in claim 4, wherein, after receiving at least one vial into the opened mouth of the envelope, said vacuum device can be deactivated to permit the envelope to slide down from said pivot table.

6. The drug filling machine as claimed in claim 1, wherein said printing unit is operable to feed the selected and printed envelope to an upper surface of said pivot table while in the first inclined position.

7. The drug filling machine as claimed in claim 1, wherein said printing unit comprises an envelope storage area for storing a number of different-sized envelopes.

8. The drug filling machine as claimed in claim 1, wherein said printing unit is operable to feed the selected and printed envelope to said envelope opening unit.
