Tablet filling device, PTP packaging machine, and method for manufacturing a PTP shee

Abstract

The present invention addresses the problem of providing a tablet filling device, a PTP packaging machine, and a method for manufacturing a PTP sheet, with which it is possible to suppress a decreasein the appearance quality of a tablet printed on both surfaces. The tablet filling device (21) is provided with: a first rotating cylinder (47) that sucks and holds tablets (5) supplied from a supply / dispensing unit (46) and transports the tablets; a first printing mechanism (50) that prints on one surface of the tablet (5) conveyed by the first rotating cylinder (47); a second rotating cylinder (48) capable of transferring the tablets (5) that have been printed on one surface thereof by the rotating cylinder (47), holding the tablets (5) by suction, and conveying the tablets (5); a second printing mechanism (51) that prints on the other surface of the tablet (5) conveyed by the second rotating cylinder (48); and a third rotating cylinder (49) that inverts the tablet (5), which has been transferred by the second rotating cylinder (48) and printed on both surfaces, so as to fill the bag section (2) of the container film (3) with the inverted tablet (5) in such a manner that the other surface printed by the second printing mechanism (51) is positioned on the upper side.

Description

technical field [0001] The present invention relates to a tablet filling device for printing on both sides of a tablet, a PTP packaging machine having the same, and a method of manufacturing PTP tablets. Background technique [0002] Generally, a PTP (bubble pack) sheet is known as a blister pack sheet used in the field of pharmaceuticals and the like. [0003] The PTP sheet is constituted by a container film forming a bag portion in which the tablet is accommodated, and an overcoat film attached to the container film so as to seal the opening side of the bag portion. [0004] This PTP sheet is produced through the following steps, etc., and the steps include: a step of forming a bag portion on a container film conveyed in a belt shape; a step of filling the bag portion with tablets; A step of installing a cover film on the container film by side sealing; a step of stamping a strip-shaped PTP film composed of a container film and a cover film according to the PTP sheet unit...

AI Technical Summary

Problems solved by technology

[0006] However, with a tablet printer such as Patent Document 1, there are many pre-printed tablets, which are put into the hopper (tablet storage unit) of the PTP packaging machine, and are sequentially filled in the container from there. In the case of producing PTP sheets in the bag part of the film, for example, in the inside of the hopper or the inside of the supply and injection part, before the tablet is filled in the bag part, the printed surface of the tablet may be scratched or chipped, and the printing will not be correct. clear danger

Especially in the case of a brittle tablet such as a chewable tablet in the oral cavity, there is a more significant risk of such adverse conditions.
