If the next prescription is started without completing the predetermined prescription (step S14), the process proceeds to step S1 and the operations of steps S1 to S12 are repeated, while the predetermined prescription is completed. Then, the medicine packaging operation ends (step S13). Thus, the reference conveyance in which the conveying speed of the conveyor 70 is read from the storage means M by the means P7 when it is detected that the sheet 300 that has not been cut by the cutter device 60 by the means P8 has moved to the belt conveyor 70. After the sheet 300 is cut by the means P6, the means P7 sets the conveyance speed to be faster than the reference conveyance speed, and the means P8 detects that the next uncut sheet 300 has moved to the conveyor 70. On the other hand, it is returned to the reference transport speed by means P7.

  In the medicine packaging device 100 described above, for example, in one (patient) prescription A, it is instructed to take powder for 3 days “after breakfast”, “after lunch”, and “after dinner” In the other patient's prescription B, if you are instructed to take powder and tablets for 2 days after breakfast, after lunch, and after dinner, first dispense according to prescription A By sequentially supplying a predetermined amount of medicine for “after breakfast”, “after lunch” and “after dinner” to the long packaging sheet 300, and sequentially sealing the long packaging sheet 300, Is formed in order along the longitudinal direction X for “after breakfast”, “after lunch”, “after dinner”, and “empty”, which are individually divided, and further based on one prescription A The packaging sheet 300 containing the supplied medicine is continuously used by the cutter device 60. Further, a package group Ha consisting of four packages h for “empty”, “after breakfast”, “after lunch” and “after dinner”, “after breakfast”, “after lunch” and “dinner” A package group Ha composed of three package bodies h for “after”, and a package group Ha composed of four package bodies “for breakfast”, “after lunch”, “after dinner” and “empty” After sequentially cutting and cutting the sheet 300 as in the transport state of the package group Ha shown in A in FIG. 6A, the conveyor 70 of the R1 between the package groups (Ha, Ha) is transported. The speed is set to a transport speed faster than the reference transport speed.

  Further, even after the medicine is packaged by one prescription A, similarly, the transport speed of the conveyor 70 in the R3 between the package groups (Ha, Hb) is set to a transport speed faster than the reference transport speed.

  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 After sequentially cutting into body groups Hb and cutting the sheet 300 as in the transport state of the package group Hb shown in B in FIG. 6 (B), the conveyor R2 between the package groups (Hb, Hb) The conveyance speed of 70 is set to a conveyance speed faster than the reference conveyance speed.

  Note that in a predetermined prescription, the sheet 300 containing the medicine is made up of a package group consisting of two package bodies h for “empty” and “after breakfast” (in the example of FIG. 7A, the package group Ha1, In the example of FIG. 7B, a package group Hb1), a package group consisting of one package h for “after breakfast”, “after lunch” or “after dinner” (of FIG. 7A) In the example, the package group Ha2, in the example of FIG. 7B, the package group Hb2), and the package group consisting of two package bodies h for “after dinner” and “empty” (example of FIG. 7A) Then, as in the conveyance state of the package group Ha3, and in the example of FIG. 7B, the package group Hb3), after cutting the sheet 300, R1 between the package groups (Ha1, Ha2), the package groups (Ha2, Ha2). ) R1, between the package groups (Ha2, Ha3), R2 between the package groups (Hb1, Hb2), R2 between the package groups (Hb2, Hb2) Package group (Hb2, Hb3) while R2, or the conveying speed of the package group (Ha3, Hb1) between conveyors 70 R3 is sometimes made faster transport speed than the reference transport speed.

  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. Even when the sheet is set to 60 mm, for example, before the sheet 300 is cut by the cutter device 60, the conveying speed of the conveyor 70 is set to the reference conveying speed corresponding to the width in the longitudinal direction X of the package h, and FIG. ) And FIG. 8B, after the sheet 300 is cut, the transport speed is set to be faster than the fastest reference transport speed among the plurality of reference transport speeds according to the width in the longitudinal direction X of the package h. Thus, the conveying speed of R1 between adjacent package groups (Ha, Ha), R2 between package groups (Hb, Hb) and R3 between package groups (Ha, Hb) after the sheet 300 is cut, Reference conveyance before the sheet 300 is cut It can be faster than the degree.

  As described above, according to the medicine packaging device 100, when the sheet 300 that has not been cut by the cutter device 60 is transferred to the conveyor 70, for example, at the timing of supplying the medicine to the sheet 300 or the timing of sealing the sheet 300. In order to match, the conveyance speed of the conveyor 70 is set to a predetermined reference conveyance speed. After the sheet 300 is cut, the conveyance speed is set to be higher than the reference conveyance speed, and the next uncut sheet 300 is transferred to the conveyor 70. Since it returns to the reference conveyance speed when the transition is made, between the adjacent package groups after the sheet 300 is cut, in the example of FIGS. 6 and 8, R1 between the package groups (Ha, Ha), (Hb, Hb). ) Between R2, (Ha, Hb) between R3, and in the example of FIG. 7, between the package groups (Ha1, Ha2), (Ha2, Ha2), (Ha2, Ha3) 1, the transport speed of R2 between (Hb1, Hb2), (Hb2, Hb2), (Hb2, Hb3), and R3 between (Ha3, Hb1) is faster than the reference transport speed before the sheet 300 is cut, Thereby, the time required for the transport operation of the package group cut by the cutter device 60 can be shortened, and the time until the package group is discharged out of the medicine packaging device 100 by the conveyor 70 is shortened accordingly. Can do. Furthermore, according to the medicine packaging device 100, not only the time required for the transport operation of the cut package group is shortened, but also adjacent package groups (for example, the package group (Ha, By separating Ha)), it is possible to prevent the conveyors 70 from interfering with each other. In addition, since the next packaging body group (the top of the next divided packaging sheet) continues to be conveyed by the conveyor 70 until it reaches the conveyor 70, the next packaging body group has reached the conveyor 70. It is possible to enter the conveyor 70 smoothly. In this way, the packaging body group smoothly enters the conveyor 70, so that clogging of the packaging body group, wrinkles and breakage in the conveyor 70 can be suppressed.
