  FIG. 20 is a conceptual diagram in which the drive shaft 54a and the driven shaft 54b are separated from each other, and is a diagram for explaining the mutual relationship between the sheet feeding roller 51, the pressing roller 53, the endless belt 57, and the pulleys 58a and 58b. .

  Note that the interval between the three pairs of the sheet feeding rollers 51 and the interval between the two pressing rollers 53 should be different depending on the width of the target PTP sheet 90 and the arrangement of the sealing portion 93. Accordingly, these intervals can be adjusted. For example, the method proposed by the present applicant shown in Patent Document 1 is the method.

  The guide portion 52 has a slope shape toward the sandwiched portion where the two rollers 51a and 51b of the sheet feeding roller 51 overlap each other, and is divided into two vertically at the center of the width of the slope. It is divided into parts 52a. This is to adjust the width of the left and right half halves 52a in accordance with the width of the PTP sheet 90.

  Further, the half halves 52a are respectively provided with side walls 59a of the stacker 59 with the tops thereof extended. A bottom plate 59b that receives a group of PTP sheets stacked on the stacker 59 is provided below the side wall 59a (the bottom of the stacker 59) so as to be flush with the slope surface of the guide portion 52. Further, on the side of the side wall 59a on the guide portion 52 side, a restricting portion 59c is provided that restricts the PTP sheet 90 from falling from the stacker 59 in the forward inclined posture toward the guide portion 52 side. The regulating portion 59c and the bottom plate 59b are spaced apart so that the lowermost PTP sheet 90 of the stacker 59 can pass therethrough.

  One of the pair of pulleys 58 a and 58 b around which the endless belt 57 is wound is provided above the guide portion 52. As for the other pulley 58b, as shown in FIGS. 19 to 21, the driven roller 51b at the center of the three pairs of sheet feeding rollers 51 also serves as the other pulley 58b.

  The roller 51b, which also serves as the pulley 58b, has a belt groove 62 for an endless belt formed on the peripheral surface (see FIG. 18), and the hook-like portions 63 on both sides of the belt groove 62 are sandwiched between the opposite rollers. It is a polymerization surface. Even when the belt 57 and the claw portion 56 are accommodated, the belt groove 62 has a depth that does not protrude from the top of the collar portion 63. Even if it reaches (see FIG. 19), it will be stored in the belt groove 62 and will not be pinched and crushed.

  Further, depending on the position of the upper pulley 58a, the front side 57a of the endless belt 57 in FIG. 17 is arranged so as to be able to travel between the guide portions 52 divided into left and right and the bottom portion of the stacker 59. In other words, the upper pulley 58a is arranged on the bottom PTP sheet 90 located at the bottom of the stacker 59 so that the endless belt 57 is stretched at a position where the claw portion 56 of the endless belt 57 can be locked. is there.

  Next, the usage method of the tablet extraction apparatus of Example 3 is demonstrated.

  First, the width of the guide portion 52, the interval between the sheet feeding rollers 51, and the intervals between the pressing rollers 53 are adjusted to be wide or narrow according to the width of the PTP sheet 90.

  When the adjustment is completed, the PTP sheets 90 are stacked on the stacker 59. After stacking, the handle 55 is manually turned in the direction of arrow K in FIG. When rotated in this manner, the drive roller 51a of the drive shaft 54a rotates, and the driven roller 51b rotates accordingly.

  When the driven roller 51b rotates, the endless belt 57 wound around the central roller (51b, 58b) travels, and the claw portion 56 provided on the endless belt 57 is engaged with the PTP sheet 90 at the bottom of the stacker. It can be stopped and fed out to the guide part 52.

  The PTP sheet 90 fed out to the guide section 52 slides down the slope of the guide section 52 that is a steep slope, falls to a sandwiching position where the sheet feed rollers 51 overlap, and is sandwiched by these sheet feed rollers 51 and is moved backward as it rotates. Will be sent to.

  As the PTP sheet 90 is fed, the tablet encapsulating portion 93 near the portion where the PTP sheet 90 is sandwiched is also sequentially pressed by the pressing roller 53, so that the pressed tablet 100 is made of aluminum on the back side of the PTP sheet 90. The foil is broken and removed as if it were ejected.

  The number of claw portions 56 provided on the endless belt 57 is not limited to one, and a plurality of claw portions 56 can be provided at an appropriate interval. This can be determined by comprehensively considering the speed of the PTP sheet taking-out processing or the distance between the stacker and the sheet feeding roller.
