Abstract

PURPOSE:To prevent the shift between perforation and cutting positions of a blister pack material due to the shrinkage thereof resulting from the cooling during traveling, by arranging a feed roller for feeding the blister pack material, a perforating mechanism and a cutting mechanism close to one another. CONSTITUTION:A perforation mechanism 2 and a cutting mechanism 3 are arranged at right angle to each other with a feed roller 4 located therebetween and all these three members are located as close to one another as possible. Main shafts 16 and 17 are moved reciprocally by operating a drive shaft in conjunction with the feed roller 4, whereby blister pack material A is perforated and cut into a predetermined size while being moved by the rotation of the feed roller 4 to form a blister pack article. The blister pack material is intermittently moved by the feed roller at a predetermined pitch. Since the perforating mechanism and the cutting mechanism are both located close to the feed roller, a drop in the material temperature when passing between these three members is slight and, therefore, the film shrinking rate is small, thereby preventing a shift between the perforation and cutting positions.

and a depression for storing tablets (see Figure 12 and Figure 12 p).
, @ ) is carved, pulled out by the index roll 108 , and reaches onto the kite rail 110 .

A tablet feeder IQIII is disposed opposite to this roller to feed tablets into the recess a.

Reference numeral 112 denotes an aluminum foil roll, and the aluminum foil Aλ is supplied to a bottom seal roll 113 together with the film a, and is heated and welded by the roll to form a PRISTAPACK material A (hereinafter simply referred to as the material). This material A passes through a kite roller 114 and a tension roller 115 and reaches a perforation forming mechanism 116, where perforations C (see FIG. 12) are formed. The product is then fed out by the feeding roller 117 and punched out to a predetermined size by the punching mechanism 118.

The punched waste is stored in a storage box 121.

Note that the feed roller 117 forms a recess for accommodating a protrusion formed by a recess a formed in the film F, as will be described later.
, 1' A are sent intermittently at predetermined pitches, and the perforation mechanism 116 and punching mechanism 118 operate in synchronization with this, and normally both models 116 and 118
are provided on both sides with a common operating gate structure 122 in between, and are operated synchronously by left and right drive of the operating mechanism.

[Problem to be solved by the invention]

The feeding speed of the material A is quite high, so the residual heat heated by the heater 104, the bottom seal roll 113, etc. remains even after the final punching step n1118. When using a conventional PvC film, the degree of thermal expansion is small and there is no problem, but recently there is a tendency to use a polypropylene film. This polypropylene has a large degree of thermal expansion, and therefore shrinkage continues even after the perforation step, which may cause a misalignment between the delivery by the delivery roller 117, the perforation setting information, and the punching position. This is inconvenient in appearance and in cutting use, and the product l[ll1lllI
! There are problems such as inferior performance.

In view of this point, it is an object of the present invention to accurately form perforations and punching without being affected by the shrinkage that occurs during cooling.

[For production]

The material is transferred from the feed roller at predetermined pitches. The above-mentioned perforation carving mechanism and punching mechanism are both disposed close to the feed roller, 1 because the temperature drop during passing between these three parts is small, and therefore the shrinkage rate of the film is small, and the perforation and punching positions are This can prevent misalignment.
