Therefore, there is a problem that the device having the higher operation capacity cannot operate at the maximum operation rate of the device, so that the efficiency is low, and the efficiency of the entire production line is low.

Further, since the primary packaging device and the cartoner must be operated at the same time, there is a problem that the degree of freedom in setting a production schedule of the PTP sheet is low. As a method of solving such a problem, there is a method of providing a temporary storage step between the two steps.

[0005] This temporary storage step means that the primary packaged P
The TP sheet is not sent to the carton process immediately, but is stored in a container such as a container and temporarily stored. After the temporary storage, when desired, the final packaged PTP sheet is taken out of a container such as a container and sent to a carton process to produce a final product.

By providing such a temporary storage step, the primary packaging apparatus and the cartoner can be operated separately and independently, so that each apparatus operates at the maximum operation rate of the apparatus. be able to. As a result, the operation rate of the entire production line is also improved. In addition, since the two devices can be operated separately and independently, the operation schedule of each device can be freely set.
