  Next, in the other prescription B, the transport speed of the belt conveyor 70 is returned to the reference transport speed, and in the same manner as in one prescription A, for “after breakfast”, “after lunch” and distributed based on the other prescription B and Each of the predetermined amount of medicine for “after dinner” is sequentially supplied to the sheet 300, and the sheet 300 is sequentially sealed in the same size as in the case of the one prescription A so that each “after breakfast” is individually divided. , “After lunch”, “after dinner” and “empty” packages h are sequentially formed along the longitudinal direction X, and the sheet 300 containing the medicine supplied based on the other prescription B For the package group Hb consisting of four package bodies h for “empty”, “after breakfast”, “after lunch” and “after dinner”, and for “after breakfast”. , “After lunch”, “After dinner” and “Empty” packages Continue to sequentially cut the body group Hb, as shown in B in FIG. 6 (A), the continue to transport the package group Hb of two days, which is the cut at reference transportation speed at the conveyor 70.

  In the predetermined prescription, as shown in FIG. 6 (B), the sheet 300 containing the medicine is packaged as a group of packages Ha1, Hb1, consisting of two packages h for “empty” and “after breakfast”. From a package group Ha2, Hb2 consisting of one package h for "after breakfast", "after lunch" or "after dinner", from two packages h for "after dinner" and "empty" Each of the package groups Ha3 and Hb3 is cut, and the cut package groups Ha1 to Ha3 and Ha1 to Ha3 are conveyed at the reference conveyance speed by the conveyor 70, and one prescription A and the other prescription B of the next stage In the meantime, the belt may be conveyed at a conveyance speed faster than the reference conveyance speed by the belt conveyor 70.

  In one prescription A, the width da in the longitudinal direction X of the package h formed on the sheet 300 is, for example, 90 mm, and in the other prescription B, the width db in the longitudinal direction X of the package h formed on the sheet 300. For example, as shown in FIG. 7, the cut package group is conveyed at a reference conveyance speed according to the width da in the longitudinal direction X of the package h during one prescription A as shown in FIG. 7. And between one prescription A and the other prescription B of the following stage, it conveys at a conveyance speed faster than the fastest standard conveyance speed of the standard conveyance speed corresponding to the width of longitudinal direction X of package h. In addition, during the other prescription B, it is possible to return to the reference conveyance speed corresponding to the width db in the longitudinal direction X of the package h.

  As described above, according to the medicine packaging device 100, the package group cut by the cutter device 60 is conveyed at the reference conveyance speed by the conveyor 70 during one prescription A, and one prescription A and the other of the next stage. Since it conveys with the conveyance speed faster than a reference | standard conveyance speed with the conveyor 70 between prescription B, and also returns to a reference | standard conveyance speed during another prescription B, about the package group conveyed by the conveyor 70, FIG. ) And FIG. 7, the distance R3 between the package group Ha in one prescription A and the package group Hb in the other prescription B is the distance R1 between the package group Ha in one prescription A and the other In the example of FIG. 6B, the distance between the package group Ha3 in one formulation A and the package group Hb1 in the other formulation B is larger than the distance R2 between the package groups Hb in the formulation B. The distance R3 is a group of packages (Ha1, Ha2), (Ha2, Ha2), ( Packaging with one prescription A is greater than the distance R1 between a2, Ha3) and the distance R2 between the package groups (Hb1, Hb2), (Hb2, Hb2), (Hb2, Hb3) in the other prescription B The body group Ha, (Ha1, Ha2, Ha3) can be easily distinguished from the package group Hb, (Hb1, Hb2, Hb3) in the other prescription B. Therefore, the mistakes in the package group can be sufficiently suppressed, and the patient The correct package can be provided.
