Abstract

In a drug packaging device which can shorten the drug packaging time. The opening of a bag is sealed with a transverse sealing unit and a longitudinal sealing unit. The time when the sealing is started and the sealing speed are varied according to the type of drug to be packaged in the bag. For drugs that take a longer time to be fed into the bag and settle in the bag, the seal starting time is delayed and the sealing speed is slowed. As a whole, it is possible to shorten the packaging time, while eliminating the possibility of incomplete packaging.

Claims

1. A drug packaging device for packaging predetermined drugs in bags by feeding said predetermined drugs into said bags through their openings and sealing the openings to close said bags, characterized in that the sealing speed at which the opening of each bag is sealed is varied according to the type of drug to be packaged in said each bag.

2. A drug packaging device as claimed in claim 1 wherein the time when the sealing of the mouth of each bag is started is varied according to the type of drug to be packaged in said each bag.

3. A drug packaging device as claimed in claim 1 wherein said seal starting time and said sealing speed are determined based on drug information supplied from a computer.

4. A drug packaging device as claimed in claim 1 wherein said seal starting time and said sealing speed are determined based on externally supplied information on the shape of the drug to be packaged.

5. A drug packaging device as claimed in claim 1 wherein said seal starting time and said sealing speed are determined based on drug information supplied from a drug stocker.

6. A drug packaging device as claimed in claim 1 wherein said seal starting time and said sealing speed are determined based on drug information recorded on a prescription and read by a scanner or a bar code reader.

7. A drug packaging device as claimed in claim 1 wherein if a plurality of kinds of drugs are fed into a single bag, the opening of said single bag is sealed at the latest of seal starting times or the slowest of sealing speeds set for said plurality of kinds of drugs.

8. A drug packaging device as claimed in claim 7 wherein if a plurality of kinds of drugs are to be continuously packaged, a seal starting time and a sealing speed are set for each of said plurality of kinds of drugs, and wherein the sealing of the opening of each bag is started at said seal starting time and carried out at said sealing speed.

9. A drug packaging device as claimed in claim 2, wherein said seal starting time and said sealing speed are determined based on drug information supplied from a computer.

10. A drug packaging device as claimed in claim 2, wherein said seal starting time and said sealing speed are determined based on externally supplied information on the shape of the drug to be packaged.

11. A drug packaging device as claimed in claim 2 wherein said seal starting time and said sealing speed are determined based on drug information supplied from a drug stocker.

12. A drug packaging device as claimed in claim 2 wherein said starting time and said sealing speed are determined based on drug information recorded on a prescription and read by a scanner or a bar code reader.

13. A drug packaging device as claimed in claim 2 wherein if a plurality of kinds of drugs are fed into a single bag, the opening of said single bag is sealed at the latest of seal starting times or the slowest of sealing speeds set for said plurality of kinds of drugs.

14. A drug packaging device as claimed in claim 3 wherein if a plurality of kinds of drugs are fed into a single bag, the opening of said single bag is sealed at the latest of seal starting times or the slowest of sealing speeds set for said plurality of kinds of drugs.

15. A drug packaging device as claimed in claim 4 wherein if a plurality of kinds of drugs are fed into a single bag, the opening of said single bag is sealed at the latest of seal starting times or the slowest of sealing speeds set for said plurality of kinds of drugs.

16. A drug packaging device as claimed in claim 5 wherein if a plurality of kinds of drugs are fed into a single bag, the opening of said single bag is sealed at the latest of seal starting times or the slowest of sealing speeds set for said plurality of kinds of drugs.

17. A drug packaging device as claimed in claim 6 wherein if a plurality of kinds of drugs are fed into a single bag, the opening of said single bag is sealed at the latest of seal starting times or the slowest of sealing speeds set for said plurality of kinds of drugs.

18. A drug packaging device as claimed in claim 2 wherein if a plurality of kinds of drugs are to be continuously packaged, a seal starting time and a sealing speed are set for each of said plurality of kinds of drugs, and wherein the sealing of the opening of each bag is started at said seal starting time and carried out at said sealing speed.

19. A drug packaging device as claimed in claim 3 wherein if a plurality of kinds of drugs are to be continuously packaged, a seal starting time and a sealing speed are set for each of said plurality of kinds of drugs, and wherein the sealing of the opening of each bag is started at said seal starting time and carried out at said sealing speed.

20. A drug packaging device as claimed in claim 4 wherein if a plurality of kinds of drugs are to be continuously packaged, a seal starting time and a sealing speed are set for each of said plurality of kinds of drugs, and wherein the sealing of the opening of each bag is started at said seal starting time and carried out at said sealing speed.

21. A drug packaging device as claimed in claim 5 wherein if a plurality of kinds of drugs are to be continuously packaged, a seal starting time and a sealing speed are set for each of said plurality of kinds of drugs, and wherein the sealing of the opening of each bag is started at said seal starting time and carried out at said sealing speed.

22. A drug packaging device as claimed in claim 6 wherein if a plurality of kinds of drugs are to be continuously packaged, a seal starting time and a sealing speed are set for each of said plurality of kinds of drugs, and wherein the sealing of the opening of each bag is started at said seal starting time and carried out at said sealing speed.

23. A drug packaging device as claimed in claim 7 wherein if a plurality of kinds of drugs are to be continuously packaged, a seal starting time and a sealing speed are set for each of said plurality of kinds of drugs, and wherein the sealing of the opening of each bag is started at said seal starting time and carried out at said sealing speed.
