Description

  The present invention relates to a PTP sheet containing a tablet and a PTP sheet manufacturing apparatus for manufacturing the PTP sheet.

  Generally, a PTP sheet containing a tablet is composed of a container film in which a pocket portion filled with tablets is formed, and a cover film attached to the container film so as to seal the opening side of the pocket portion. Yes.

  In manufacturing the PTP sheet, an inspection regarding cracking of the tablet or the like is performed. In the PTP sheet, the container film is generally formed of a transparent resin material such as PP (polypropylene), and the cover film is formed of a metal material such as aluminum that does not have translucency. After the tablets are filled, an inspection using transmitted light has been performed at a stage before the cover film is attached. For example, the container film is irradiated with light from the irradiation means, and on the opposite side, the presence or absence of cracking of the tablet is determined depending on whether light transmitted between one tablet piece and the other tablet piece is detected. Can be inspected (see, for example, Patent Document 1).

  In recent years, from the viewpoint of improving light-shielding properties, moisture-proof properties, and the like, even container films are often formed of aluminum or the like (see, for example, Patent Document 2). In such a case, since inspection using transmitted light as in the prior art cannot be performed, inspection using reflected light is performed.

  However, as shown in FIG. 12, in the pocket part 70, when one tablet piece 75a of the cracked tablet 75 and the other tablet piece 75b stick together in the state immediately after molding, the reflected light is reflected. In the inspection used, since the cracked portion 76 of the tablet 75 is detected as a streaky dark portion, it is difficult to detect the cracked portion 76 of the tablet 75 as compared to the inspection using transmitted light.

  Furthermore, in the inspection using reflected light, not only the cracks of the tablet but also foreign matters such as hair attached to the tablet, and the pre-formed tablet secant are detected as streaky dark parts. It was difficult to determine whether the detected one was cracked or not.

  As a result, there is a possibility that the inspection accuracy is lowered.

  In addition, the said malfunction may occur not only when the container film is formed with metal materials, such as aluminum, but also when it is formed with the resin material etc. which have light-shielding property.

  The present invention has been made in view of the above circumstances, and has as one of its main purposes to provide a PTP sheet capable of improving inspection accuracy and a PTP sheet manufacturing apparatus for manufacturing the PTP sheet. Yes.

  Hereinafter, each means suitable for solving the above-described problem will be described separately. In addition, the effect specific to the means to respond | corresponds as needed is added.

  Hereinafter, an embodiment will be described with reference to the drawings.

  As shown in FIGS. 1A to 1C, the PTP sheet 1 is attached to the container film 3 having a plurality of pocket portions 2 and the back side of the container film 3 so as to close the pocket portions 2. And a cover film 4. Both the container film 3 and the cover film 4 in this embodiment are formed of an aluminum laminate film.

  The PTP sheet 1 is manufactured into a sheet shape by punching a strip-shaped PTP film 6 (see FIG. 1B) formed from the container film 3 and the cover film 4.

  As shown in FIG.1 (c), each pocket part 2 accommodates the tablet 5 one each. In the present embodiment, a lens lock having a substantially circular shape in plan view is accommodated as the tablet 5. Correspondingly, the pocket portion 2 is also formed in a substantially circular shape in plan view.

  Furthermore, the bottom part 2a of each pocket part 2 is provided with a convex part 2b projecting inward. The convex portion 2b in the present embodiment is formed in a substantially circular shape in plan view, and is curved and formed in a substantially arc shape in cross section.

  Next, the outline of the PTP packaging machine 8 as a PTP sheet manufacturing apparatus for manufacturing the PTP sheet 1 will be described.

  As shown in FIG. 2, on the uppermost stream side of the PTP packaging machine 8, the raw material of the strip-shaped container film 3 is wound in a roll shape.

  In the PTP wrapping machine 8, the container film 3 wound in a roll shape is intermittently transferred, and along the transfer path of the container film 3, a pocket part forming device as a pocket part forming means 14 is arranged.

  The pocket portion 2 is formed on the container film 3 by the pocket portion forming device 14. The pocket portion 2 is formed at intervals between the transfer operations of the container film 3 by cold working.

  Furthermore, along the transfer path of the container film 3 in which the pocket portion 2 is formed, a tablet loading device 16 as loading means, an inspection device 17 as inspection means, and a film receiving roller 18 are disposed.

  The tablet loading device 16 freely drops the tablet 5 by opening the shutter at predetermined intervals, and the tablet 5 is loaded into each pocket portion 2 in accordance with the shutter opening operation.

  The inspection device 17 includes an illumination device 17a as an illumination unit, a camera 17b as an imaging unit, and the like (see FIG. 9). As shown in FIG. 9, the illumination device 17a and the camera 17b are arranged on the opening side (upper side in FIG. 9) of the pocket portion 2. Under such a configuration, light emitted from the illumination device 17a illuminates the tablet 5 and the like, and light reflected from the tablet 5 and the like is imaged by the camera 17b. And the inspection apparatus 17 performs the test | inspection regarding the presence or absence of a crack of the tablet 5, mixing of a foreign material, etc. based on the image data imaged with the camera 17b.

  Moreover, the raw material of the cover film 4 formed in the strip | belt shape is wound by the roll shape in the most upstream side.

  The drawing end of the cover film 4 wound in a roll shape is guided toward the film receiving roller 18. A heating roller 19 can be pressed against the film receiving roller 18, and the container film 3 and the cover film 4 are sent between the rollers 18 and 19. Then, the container film 3 and the cover film 4 pass between the rollers 18 and 19 in a heated and pressed state, so that the cover film 4 is adhered to the back side of the container film 3 and the pocket portion 2 is closed with the cover film 4. Can be removed. Thereby, the PTP film 6 with which the tablet 5 was filled in each pocket part 2 is manufactured. The film receiving roller 18 and the heating roller 19 constitute attachment means in this embodiment.

  On the downstream side of the film receiving roller 18, a perforation forming device 22, a marking device 23, and a sheet punching device 24 are sequentially arranged along the transfer path of the PTP film 6. The perforation forming device 22 has a function of forming perforations at predetermined positions on the PTP film 6. The marking device 23 has a function of attaching a stamp indicating identification information such as a lot number to a predetermined position of the PTP film 6. The sheet punching device 24 has a function as a sheet punching unit that punches the PTP film 6 into one PTP sheet.

  A scrap hopper 26 for storing the end material 25 from the sheet punching device 24 is provided on the downstream side of the sheet punching device 24. In addition, a conveyor 28 for transferring the punched PTP sheet 1 is provided below the sheet punching device 24. The punched PTP sheet 1 is transferred to a finished product hopper 29 by the conveyor 28. After that, the PTP sheets 1 accommodated in the finished product hopper 29 are set so that two pockets 2 face each other and the pocket portions 2 face each other, and a plurality of sets are accumulated and stacked. Eventually, they are guided to a band (bundling) process or a bag making process and packed in a box. However, when a defective product is determined by the inspection device 17, the PTP sheet 1 that has been determined to be defective is separately discharged by a defective sheet discharge mechanism (not shown).

  The container film 3 and the PTP film 6 are conveyed through a plurality of rollers as shown in FIG. Among these rollers, the rollers 18, 31, 32, 33, 34, and 35 facing the bulging side of the pocket portion 2 have a positional relationship in which the roller surface and the pocket portion 2 face each other. Since the concave portion for accommodating the pocket portion 2 is formed on the surface of the roller 18 or the like, the pocket portion 2 is not basically crushed. Further, the feeding operation is performed while the pocket portion 2 is housed in each recess such as the film receiving roller 18, so that the intermittent feeding operation and the continuous feeding operation are reliably performed.

  Although the outline of the PTP packaging machine 8 is as described above, the pocket portion forming apparatus 14 will be described in detail below.

  As shown in FIG. 3, the pocket portion forming apparatus 14 includes a lower mold 41 as a first mold and an upper mold 42 as a second mold. A cylindrical lower mold chamber 44 is fixed on the support base 43 in a fixed state, and the lower mold 41 is fixed on the lower mold chamber 44. In the lower mold 41, a plurality of hole portions 45 are formed at positions corresponding to the positions of the pocket portions 2.

  A plurality of insertion holes are formed in the support base 43, and a rod-shaped slider 46 is inserted into the insertion holes through a bearing mechanism so as to be movable up and down. The slider 46 can be moved up and down between predetermined strokes by the cam mechanism 50. A plate 47 is fixed to the upper end of the slider 46, and a plug base 48 is placed and fixed on the plate 47.

  The plug base 48 has a molded plug 49 that can be inserted into the hole 45 and extends upward. The forming plug 49 constitutes the pocket forming die in this embodiment. The tip shape of the molding plug 49 is substantially the same as the inner shape of the pocket portion 2. That is, a forming concave portion 49 a for forming the convex portion 2 b of the bottom portion 2 a of the pocket portion 2 is formed at the tip portion of the molding plug 49. The forming concave portion 49a is formed in a substantially arc shape in cross section corresponding to the convex portion 2b.

  Further, the plate 47, the plug base 48, and the molded plug 49 can be moved up and down by the vertical movement of the slider 46 driven by the cam mechanism 50.

  On the other hand, an upper plate 51 is provided above the container film 3. A plate 52 is fixed to the lower surface of the upper plate 51, and the upper mold 42 is fixed to the plate 52.

  The upper plate 51, the plate 52 and the upper mold 42 can be moved up and down by a cam mechanism 54. And the container film 3 is clamped by both the molds 41 and 42 by lowering the upper mold 42 and bringing it into contact with the lower mold 41 in a fixed state.

  The upper mold 42 is also provided with a hole 53 similar to the lower mold 41. A pusher 55 is accommodated in each hole 53 so as to be movable up and down. The pusher 55 has a convex cross-sectional shape that protrudes downward.

  In addition, a restricting portion 53a that restricts the pusher 55 from falling off is formed in the vicinity of the opening of each hole 53 (see FIG. 4 and the like). A coil spring 56 as an elastic body is accommodated between the pusher 55 and the plate 52 in a contracted state. As a result, the pusher 55 is normally biased downward.

  Further, a forming convex portion 55 a for forming the convex portion 2 b of the bottom portion 2 a of the pocket portion 2 is formed at the tip portion of the pusher 55. The front end surface of the forming convex portion 55a is formed in a substantially circular arc shape corresponding to the convex portion 2b. The forming recess 49a of the molded plug 49 and the forming protrusion 55a of the pusher 55 constitute the protrusion forming means in this embodiment.

  Next, the process of forming the pocket portion 2 on the container film 3 will be described.

  During normal operation, that is, during conveyance of the container film 3, the upper mold 42 is separated from the lower mold 41 and is positioned above (see FIG. 4). In this state, the molded plug 49 is retracted in the hole 45 and is separated from the container film 3 downward.

  And when conveyance of the container film 3 is stopped, the upper mold | type 42 will descend | fall and the container film 3 will be clamped by the said upper mold | type 42 and the lower mold | type 41 (refer FIG. 5).

  Subsequently, the molding plug 49 starts to rise and presses the container film 3 (see FIG. 6). When the forming plug 49 is raised by a predetermined amount, the container film 3 is sandwiched between the forming concave portion 49 a of the forming plug 49 and the forming convex portion 55 a of the pusher 55. That is, the container film 3 has a shape along the molding surface of the tip portion of the molding plug 49, and portions corresponding to the bottom portion 2 a and the convex portion 2 b of the pocket portion 2 are formed.

  In this state, the molded plug 49 further rises while pushing up the pusher 55 against the urging force of the coil spring 56, and stops at a preset position (see FIG. 7). Thereby, the pocket part 2 having a predetermined depth is formed in the container film 3.

  Thereafter, after the upper die 42 is lifted and separated from the lower die 41, the molding plug 49 is retracted into the hole 45, and the formation process of the pocket portion 2 is completed (see FIG. 8).

  As described above in detail, according to the present embodiment, the convex portion 2 b is provided on the bottom portion 2 a of the pocket portion 2. Thereby, as shown in FIG. 9, the normal tablet 5 put into the pocket portion 2 from the tablet loading device 16 is supported by the convex portion 2b of the bottom portion 2a of the pocket portion 2 as shown in FIG. The vicinity is accommodated in the pocket portion 2 in a state where it floats from the bottom portion 2a. On the other hand, as shown in FIG. 10, when the cracked tablet 5 is put into the pocket portion 2, the tablet 5 is clearly defined for each tablet piece 5 a, 5 b in the pocket portion 2 by its own weight. Easy to be separated. Furthermore, in this embodiment, since the convex part 2b of the pocket part 2 becomes the shape curved in cross-sectional arc shape, the said effect can be improved more.

  As a result, when the inspection is performed in the inspection device 17, the cracks of the tablet 5 can be clearly distinguished from the foreign matter and the secant, and the inspection accuracy can be improved.

  In addition, the container film 3 made of aluminum is more likely to be plastically deformed and less likely to be restored to its original shape as compared to those formed from a resin material such as PP or PVC. By providing the convex portion 2b in the pocket portion 2 as in the embodiment, the strength of the pocket portion 2 can be improved. As a result, it is possible to prevent crushing deformation of the pocket portion 2 due to a pressure from the outside during the accumulation of the PTP sheet 1 or a difference in internal and external pressures of the pocket portion 2 after the cover film 4 is heated and stuck.

  Moreover, in the said embodiment, since the convex part 2b can be formed in the bottom part 2a simultaneously with formation of the pocket part 2, the improvement of production efficiency can be aimed at. Furthermore, since the pusher 55 is configured to be displaceable following the operation of the molding plug 49, manufacturing errors of the molding plug 49 and the pusher 55 can be absorbed, so that the convex portion 2 b of the pocket portion 2 is more appropriate. It can be formed in any shape.

  In addition, it is not limited to the description content of the said embodiment, For example, you may implement as follows. Of course, other application examples and modification examples not illustrated below are also possible.
