Description

technical field

[0001] The invention relates to a film heating forming method of a blister packaging machine. Background technique

[0002] Conventionally, in a blister pack for packaging tablets such as medicines using a film such as a PVC film, a long film that is released continuously intermittently is sandwiched between a flat plate that is arranged facing each other and moves in the contact / separation direction. Heating the space between the discs and performing desired heating, using a molding die to form pockets for accommodating one or more tablets on the heat-softened film, and then supplying tablets to each pocket, by having the pocket The aluminum film is attached to the film to seal the pockets, and a sheet is cut in such a way that the desired number of pockets are present to form a product.

[0003] In addition, the forming of the film in the above-mentioned conventional blister packaging machine generally utilizes a roll formed by winding a sheet-shaped PVC f...

Embodiment Construction

[0028] Hereinafter, embodiment of the thermoforming apparatus of the film in the blister packaging machine of this invention is demonstrated based on drawing.

[0029] Figure 1 ~ Figure 3 An example of the film thermoforming device of the blister packaging machine of the present invention is shown.

[0030] The blister packaging machine as figure 1 As shown, the film F that is sequentially released from the film roll R1 formed by winding a film F such as a polypropylene film passes through the film connecting device 1 and is released by the discharge roller 2. After the tension is adjusted by the constant tension roller 3, it is released by the guide roller 4. It is intermittently supplied to the next thermoforming device 5. Here, after forming the required pockets, the tablets are supplied to each pocket by the tablet supplying device 8 via the guide roller 6 and the forming film conveying roller 7. After tableting, the aluminum film roll R2 formed by winding the sheet-sh...
