  Reference numeral 60 denotes a motor, and 61 denotes an output shaft of the motor 60. The output shaft of the motor 60 is rotatably supported by a bracket 71 provided on the frame 70 via bearings 72a and 72b. A shaft 63 (hereinafter referred to as an eccentric shaft) is provided, and the eccentric shaft 63 is rotatably connected to the upper portion of the arm 55 via a bearing 64.

Next, the operation of the sheet punching device 20 configured as described above will be described.
When the motor 60 rotates, the disc 62 provided on the output shaft 61 rotates, and the eccentric shaft 63 provided on the disc rotates along the outer peripheral edge of the disc 62. When the eccentric shaft 63 is directed to the top dead center (upward stroke), the arm 55, the punch joint 50, the punch holder 26, the punch 41, and the sheet presser 35 that are connected to the eccentric shaft 63 are also lifted. When the top dead center is reached, as shown in FIG. 3, the punch holder 26 is positioned at the uppermost position, and a gap G is formed between the punch base 21 and the sheet presser 35.

When the eccentric shaft 63 moves from the top dead center to the bottom dead center (lowering stroke), the arm 55, the punch joint 50, and the punch holder 26 are lowered. First, the sheet presser 35 comes into contact with the punch base 21, and then, When the eccentric shaft 63 reaches the bottom dead center, the lower portion of the punch 41 inserted into the elongated hole 36 of the sheet presser 35 enters the opening 22 of the punch base 21.
When the punch 41 enters the opening 26 of the punch base 21 or slightly before that, the compressed air sent from the compressed air pressure source is ejected from the nozzle holes 43 through the air holes 30.

  Now, when the pocket 15 is filled with tablets or the like, the aluminum film 7 is stuck, and the continuous PTP sheet 14 is fed onto the punch table 21 from the direction of arrow a (the direction perpendicular to the paper surface in FIG. 3), the punch 41 Stop right under. On the other hand, the motor 60 is driven in synchronism with the feeding of the PTP sheet 14, and the eccentric shaft 63 moves to the lowering process, and the punch holder 26 is lowered.

  First, the periphery of the PTP sheet 14 is pressed by the sheet presser 35, and then the punch 41 is lowered to punch the PTP sheet 14 into a predetermined shape (see the cut line 17 in FIG. 2). At this time, the pocket 15 of the PTP sheet 14 is located in the recess 42 of the punch 41 and is not damaged. In synchronism with the punching of the PTP sheet 14, the compressed air is injected from the nozzle holes 43 provided in the punch 41, and the punched PTP sheet 14 a is moved in the direction of the arrow b from the opening 22 of the punch table 21 as it is. It is forcibly dropped onto the transfer line 19.

  When the punching of the PTP sheet 14 is finished, the eccentric shaft 63 moves to the ascending stroke, the punch holder 26, the punch 41, and the sheet presser 35 are raised, and a gap G is formed between the punch table 21 and the sheet presser 35, and the punch 41 The PTP sheet 14 is again fed directly under and punched out. Thereafter, this operation is repeated.

  As described above, the sheet punching apparatus according to the present invention forces each PTP sheet 14a punched by the punch 41 to remain in the punched posture by the compressed air sprayed from the nozzle hole 43 provided in the punch 41. In particular, it is made to fall on the conveying line 19. In order to drop the punched PTP sheet 14a without changing the posture, it is necessary to blow the compressed air from the nozzle hole 43 onto the surface of the PTP sheet 14a in a balanced manner. It is desirable to provide one at the center of 41 or a plurality at a symmetrical position in the front-rear or left-right direction.

Next, the operation of a packaging device such as a tablet provided with the sheet punching device 20 as described above will be described with reference to FIG.
The film 2 fed out from the paper tube 1 is fed to the heating roll 4 and heated, and a plurality of pockets are formed at predetermined positions by the molding drum 3.

  The film 2 provided with the pocket is conveyed onto the guide plate 11 through the idler 5, and tablets or the like are dropped from the outlet 13 of the hopper 12 into each pocket of the film 2 and filled. A mechanism for aligning a predetermined number of tablets and sequentially filling the pockets is provided between the hopper 12 and the film 2, but the description thereof is omitted.

On the other hand, the aluminum film 7 fed out from the stock roll 6 is superposed on the surface where the tablet etc. of the pocket of the film 2 conveyed on the guide plate 11 is exposed at the position of the idler 8, and the seal drum 9 and the seal roll 10 are overlapped. To form a continuous PTP sheet 14.
The continuous PTP sheet 14 is perforated by a slitter 18, and then punched into individual PTP sheets 14 a by the punching device 20 and dropped onto the transport line 19 as it is and transported. . Inspected in the inspection process, defective products are automatically discharged, and a predetermined number of non-defective products are stacked and bundled, and are shipped in a box as necessary. In addition, the process after the PTP sheet 14 is punched with the punching apparatus 20 is not limited to the above, and may be another process.

  According to the present invention configured as described above, the PTP sheet 14a punched by the punching device 20 is placed on the transport line 19 that moves in the same posture by the compressed air blown from the nozzle hole 43 provided in the punch 41. Since it falls in an orderly manner, it is not necessary to correct the posture in the subsequent steps as in the prior art, so that productivity can be improved.

In the above description, the case where the present invention is implemented in the illustrated packaging device such as a tablet is shown, but the present invention can also be implemented in packaging devices such as tablets having other structures.
Moreover, although the case where this invention was implemented to the packaging apparatus of one row of PTP sheets was shown in said description, the punching apparatus which concerns on this invention can be implemented also to the PTP sheet provided in multiple rows in the width direction of the sheet | seat. it can. In such a case, for example, a punch base, a punch holder, a sheet presser, a punch, etc. are formed long in the vertical direction (width direction) of the paper surface of FIG. 3, or each sheet presser corresponding to a row of PTP sheets, What is necessary is just to change suitably, such as providing a punch etc.

It is explanatory drawing of packaging apparatuses, such as a tablet which concerns on one embodiment of this invention. It is explanatory drawing of the continuous PTP sheet. It is a longitudinal cross-sectional view of the sheet punching device of FIG. FIG. 4 is a left side view of FIG. 3. FIG. 2 is an exploded perspective view of FIG. 1 with a part thereof omitted.
