Abstract

The drying unit (30) of the tablet printing device has a blower fan (81) for forming an air flow, a heater (82) for heating the gas, and a plurality of ejection ports (31) for ejecting the heated air to the tablet . A plurality of ejection ports (31) are respectively provided at positions facing the conveyed tablets (9). In this way, it is possible to suppress blowing of the heated gas laterally to the tablet (9) being conveyed. Therefore, it is possible to suppress the blowing of the tablet (9) being conveyed, and to strengthen the gas blown to the tablet. As a result, the ink adhering to the surface of the tablet (9) can be dried efficiently.

Description

technical field [0001] The present invention relates to a drying unit for drying ink adhering to the surface of a tablet, a tablet printing apparatus having the drying unit, and a drying method. Background technique [0002] A character or a serial number for identifying a product is printed on the surface of a tablet which is one form of a drug. Such characters and numbers may be printed by engraving, but the engraving has a problem of low visibility. In particular, in recent years, the spread of generic drugs has led to the diversification of the types of tablets. Therefore, in order to easily identify the tablet, a technique of clearly printing the surface of the tablet by an inkjet method is attracting attention. [0003] In the inkjet tablet printing apparatus, ink droplets (hereinafter, simply referred to as “ink droplets”) are ejected from a plurality of nozzles onto the tablet while the tablet is being conveyed. Then, by drying the ink adhering to the surface of t...
