In this state, the seal roll 98 is pressed firmly. push, forcible press}, crushing of pocket portion 95; crushing, collapse}, bending of the film general part between the pocket part 95, wrinkles in the cover film 97 which were taken, etc. There is a possibility that the situation or condition is bad. As a result, the occurrence of product defects may increase.

In general, the PTP sheet has a container film made of a resin material such as PP (polypropylene), and a cover film is made of a metal material such as aluminum, but in recent years, such as light shielding properties and moisture resistance It is also seen that even the container film was formed by aluminum etc. from a viewpoint of improving. Aluminum and the like have poor workability (ductility) as compared with the resin material, and it is necessary to design the pocket portion relatively large. In addition, aluminum and the like have no elasticity and are easy to be plastically deformed in comparison with the resin material. Therefore, aluminum or the like is difficult to restore to its original shape when deformed. As a result, there exists a possibility that the said defect may appear more remarkably.

This invention is made | formed in view of the said situation, and it is one of the main objectives to provide the PTP sheet manufacturing apparatus which can reduce generation | occurrence | production of a defective article in manufacturing a PTP sheet.

Hereinafter, each means suitable for solving the said subject is classified and demonstrated. In addition, specific effects are added to the corresponding means as necessary.

Means 1. with respect to the band-shaped container film, pocket portion forming means for forming a pocket portion for accommodating the contents;

Charging means for filling the contents into the pocket part;

Seal means for attaching a strip-shaped cover film to the container film in which the contents are filled in the pocket part so as to close the pocket part;

In the PTP sheet manufacturing apparatus provided with the sheet | seat punching means which punches the strip | belt-shaped PTP film in which the said cover film was carried to the said container film by PTP sheet unit,

The seal means,

To the film support roll which has a pocket support recess which can accommodate the pocket part of the said container film, and can convey the said container film by its rotation, engaging the said pocket part by the said pocket support recess, and the said film support roll. As a structure which attaches the said cover film with respect to the said container film by providing the sealing roll which can be crimped | bonded, and inject | pouring the said both films between the said rolls, and heat-welding,

The film support roll,

And an approximately polygonal pillar shape having a plurality of flat surfaces orthogonal to its radial direction on its outer circumferential surface, and having the pocket support recesses on each of the flat surfaces.

The term " approximately polygonal columnar shape " herein includes not only a perfect polygonal column shape in which a plurality of corners are sharp, but also rounded corners.

2. The length of each said flat surface in the circumferential direction of the said film support roll is a long side of the said PTP film. The PTP sheet manufacturing apparatus as described in the means 1 characterized by having a length corresponding to n pitch fraction (n is a natural number of 1 or more) of the sheet formation pitch of the said PTP sheet in a longitudinal direction.

Means 3. The seal roll has a columnar shape, characterized in that the PTP sheet production apparatus according to Means 1 or 2.

Means 4. The PTP sheet manufacturing apparatus according to any one of Means 1 to 3, wherein the pocket receiving recess is formed such that its inner circumferential side surface is perpendicular to the flat surface.

5. The said container film and the said cover film were formed using aluminum as a main material, The PTP sheet manufacturing apparatus in any one of the means 1-4 characterized by the above-mentioned.

Here, "it is formed with aluminum as a main material" is not only the case where it is formed by aluminum single body, but also includes the aluminum laminated film in which the resin film layer was interposed.

In addition, as described in the above-mentioned problems, defects such as dent deformation and the like of the pocket part are made of a material containing aluminum as a main component than when the container film is made of a resin material such as polypropylene (PP) or polyvinyl chloride (PVC). It tends to occur in the case of being made. Compared with the above resin material, it is considered that aluminum is more likely to be plastically deformed, and it is difficult to restore the original shape once it is deformed by stress.

[1] According to the said means 1, the pocket part formation means forms a pocket part for accommodating a content with respect to a strip | belt-shaped container film, and a cover film is taken out in a sealed state so that a pocket part may be closed by a sealing means. As a result, a strip-shaped PTP film is produced. The sealing means includes a film support roll having a pocket support recess that can accommodate the pocket portion, and a seal seal for heating. The attachment of the cover film heats the container film and the cover film with both rolls after the contents are accommodated in the pocket portion. By pressing. And a PTP sheet is punched out of a PTP film by a punching means.

And according to this means, the film support roll forms the substantially polygonal column shape which has the several flat surface orthogonal to the radial direction in the outer peripheral surface, and has the structure which has the said pocket support recessed part in each flat surface. Thereby, this container film can be appropriately hanged on a film support roll, without applying excessive stress to the pocket part of a container film, and the film general part around it. As a result, since the film general part around a pocket part can be sealed in a flat state, it can suppress that various defects generate | occur | produce, such as a distortion of a pocket part, the bending of the film general part between pocket parts, and the wrinkles in the cover film which were taken out. It is possible.

Moreover, in order to suppress the said defect, it is also conceivable to employ | adopt the apparatus of the structure which conveys a container film etc. in the state which extended | stretched straight, without using various rolls. At the same time, the entire line is intermittently sent to pocket molding or the like. feed; Conveying} operation, the production speed is hindered. Moreover, although it is also possible to enlarge the diameter of a film support roll, and to prevent the dent of a pocket part, etc., it is similarly worried about the enlargement of an apparatus. According to this point, according to this means, it is possible to increase the production speed and to suppress the enlargement of the device by the continuous sending operation using the roll.

In the case where the container film is made of a resin material, the container film is heated at the time of forming the pocket portion, and there is a possibility that curl may occur due to subsequent heat shrinkage. } Cooling is required. In other words, in the apparatus which conveys a film without using the various rolls mentioned above, it is difficult to manufacture a PTP sheet which a container film consists of a resin material. According to this point and this means, by using a roll, any case where a container film consists of a resin material, aluminum, etc. can be responded suitably.

[2] According to the said means 2, since each flat surface of a film support roll is formed in the range corresponded to n sheet | seat part of a PTP sheet, the whole area | region of each PTP sheet can be sealed in a flat state, The said The effect of the means 1 and the like can be made more reliable in PTP sheet units.

In particular, when the container film is made of a resin material, since the container film is heated at the time of forming the pocket portion, after the container film and the cover film are adhered to each other, there is a possibility that curling may occur due to a difference in these heat shrinkage rates. have. According to this point, this means can suppress generation of such curls.

In addition, about the part corresponding to the corner | angular part (non-flat part) of a film support roll, although there exists a possibility that bending may arise in a PTP film, since this bending part becomes a boundary part of PTP sheets, the said bending part at the time of sheet punching When the PTP sheet is punched in the range except for the warping, It is possible to obtain a PTP sheet without warping, warpage}.

In addition, the bent portion is marked. By using it as a target}, it becomes possible to perform a subsequent process (for example, a sheet punching process, etc.) more correctly.

[3] According to the above means 3, the container film and the cover film are sealed by press-contacting the substantially polygonal film supporting roll and the cylindrical seal roll. By setting it as such a structure, for example, both of a film support roll and a seal roll have a polygonal column shape, and rather than the structure which seals a container film and a cover film, pressing the flat surfaces of both, It is easy to absorb the assembly error of each roll, and can perform a stable seal at a more uniform pressure. Moreover, only the film support roll side is replaced without replacing the seal roll side, and it can respond to various varieties and can improve versatility.

[4] According to the above means 4, the inner peripheral side of the pocket receiving recess is formed to be orthogonal to the flat surface, whereby the flat surface at the end face of the film receiving roll orthogonal to the rotation axis of the film receiving roll. And the angle α formed by the radial line connecting the boundary between the pocket receiving recess and the rotation center of the film receiving roll and the flat surface, and the flat surface becomes smaller than 90 °.

In the past, generally, the inner circumferential side of the pocket support recess was formed along the radial direction of the film support roll. In other words, the inner circumferential side of the pocket receiving recess was perpendicular to the rotation direction of the film receiving roll. For this reason, the stress F was applied to the roll rotation direction with respect to the pocket part at the time of film conveyance, According to this means, the load applied to a pocket part can be reduced by Fxsin (alpha) minutes. As a result, generation | occurrence | production of the distortion of a pocket part, etc. can be suppressed.

The seal roll 19 can be press-bonded to the film support roll (sending roll) 18, and the container film 3 and the cover film 4 are let in between the rolls 18,19. And the cover film 4 adheres to the back surface side of the container film 3 by passing the container film 3 and the cover film 4 between the both rolls 18 and 19 in a hot pressing state, and the pocket part (2) is occluded with the cover film (4). Thereby, the PTP film 6 in which the tablet 5 was filled in each pocket part 2 is manufactured.

Downstream of the sealing device 10, along the conveyance path of the PTP film 6, a dotted line hole forming device 22, a stamping device 23, and a sheet punching device ( 24) is excreted in turn. The missing eye forming apparatus 22 has a function of forming a missing eye at a predetermined position of the PTP film 6. The marking device 23 has a function of adding 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 sheet punching means for punching the PTP film 6 in units of the PTP sheet 1.

On the downstream side of the sheet punching device 24, the cutting material 25 from the sheet punching device 24 is stored. A scrap hopper 26 for accumulate is provided. Moreover, the conveyor 28 for conveying the punched PTP sheet 1 is provided in the lower side of the sheet punching apparatus 24. As shown in FIG. The punched PTP sheet 1 is transferred to the finished product hopper 29 by the conveyor 28. Thereafter, the PTP sheet 1 accommodated in the finished product hopper 29 is set in such a manner that the pocket portions 2 face each other in a set of two sheets. It is accumulated and stacked one by one. Finally, it is guided by a band (binding) process or a bag manufacturing process, and box packing is carried out. However, when a defective article is determined by the inspection apparatus 17, the PTP sheet 1 which became the defective article determination is discharged separately by the defective sheet discharge mechanism not shown.

In addition, the container film 3 and the PTP film 6 are conveyed through several feed rolls 18, 30, 31, 32, 34, 36, 37, 38, as shown in FIG. It is supposed to be. In these sending rolls 18 etc., the pocket support recessed part 43 corresponding to the pocket part 2, such as the container film 3, is formed in the outer peripheral surface (refer FIG. 3). The formation space | interval of the pocket support recessed part 43 with respect to the circumferential direction, such as a feed roll 18, and the formation space | interval of the pocket part 2 with respect to the longitudinal direction, such as the container film 3, are equal. . Thereby, the feed roll 18 etc. rotate and drive by the predetermined drive means, accommodating the pocket part 2 to the pocket support recessed part 43, and the container 2 is not crushed, and a container is not crushed. Transfer of the film 3 etc. is performed.

However, in this embodiment, while the feed rolls 18 and 34 carry out a continuous sending operation (continuous rotation), the other feed rolls 30-32 and 36-38 are the pocket part forming apparatus 14 and a sewing machine. The intermittent operation (intermittent rotation) is performed in accordance with the operations of the eye forming device 22, the imprinting device 23, the sheet punching device 24 and the like.

For this reason, tension rolls 33 and 35 are provided between the feed rolls 32 and 34 and between the feed rolls 18 and 36, respectively, and between the feed rolls 32 and 34 and the feed roll 18, respectively. , Warpage of the container film 3 or the like due to a difference in conveyance operation between 36); deflection} is controlled, and the container film 3 or the like is kept and kept in a constant tension state at all times.

Although the outline of the PTP packaging machine 8 is as above, the structure of the sealing apparatus 10 is demonstrated in detail with reference to FIG. 3 below.

As mentioned above, the sealing apparatus 10 is comprised by the film support roll 18 and the seal roll 19. As shown in FIG.

The film support roll 18 of this embodiment forms the substantially octagonal column shape whose cross-sectional shape orthogonal to the rotating shaft 18a became substantially square octagonal shape. Thereby, eight flat surfaces 41 are formed in the film support roll 18 at the outer peripheral surface thereof orthogonal to the radial direction thereof and along the rotational axis 18a direction.

Each flat surface 41 has the length whose length S (refer FIG. 3) in the circumferential direction of the film support roll 18 is equivalent to the sheet formation pitch P (refer FIG. 4) of the PTP sheet 1, and have. Therefore, each of the flat surfaces 41 is provided with two rows of pocket support recesses 43 which can accommodate the pocket portions 2 such as the container film 3.

The film support roll 18 is rotationally driven by a predetermined motor, and is applied by its rotation while engaging the pocket 2 such as the container film 3 by the pocket support recess 43. The container film 3 etc. are conveyed continuously.

As shown in FIG. 5A, the pocket support recess 43 is formed such that its inner circumferential side surface 43a is perpendicular to the flat surface 41. Thereby, at the cross section of the said film support roll 18 orthogonal to the rotating shaft 18a of the film support roll 18, the boundary part A of the flat surface 41 and the pocket support recessed part 43, and the film support roll The angle α formed by the radial straight line L connecting the rotation center O of (18) and the flat surface 41 becomes smaller than 90 degrees.

As shown in FIG. 5B, in the conventional film support roll 70, the inner circumferential side surface 71a of the pocket support recess 71 was formed along the radial direction of the film support roll 70. . In other words, the inner circumferential side surface 71a of the pocket base recess 71 was perpendicular to the rotational direction K of the film base roll 70. For this reason, at the time of film conveyance, since the stress F was added to the roll rotation direction K with respect to the pocket part 2 of the container film 3 from the inner peripheral side 71a of the pocket support recessed part 71, this implementation According to the configuration of the aspect, the load applied to the pocket portion 2 can be reduced by F x sinα minutes. As a result, generation | occurrence | production of the distortion of the pocket part 2, etc. can be suppressed.

Returning to the description of FIG. 3, the seal roll 19 has a cylindrical shape in which the cross-sectional shape orthogonal to the rotation axis 19a becomes a circular shape. The seal roll 19 is configured to be heated to a predetermined temperature by a predetermined heating means. Moreover, in order to realize a firm seal, the grid | lattice-shaped mesh which was formed in the slightly convex shape on the outer peripheral surface of the seal roll 19; mesh, net} is formed (not shown).

The seal roll 19 is free to rotate at one end of the predetermined arm 51. freely}. The arm 51 is tilted by making its pivot shaft 52 a point. tilting}. On the other end side of the arm 51, the bias which consists of a cylinder, a spring, etc .; urging and energizing means 53 are provided. As a result, the seal roll 19 is always pressed to the film support roll 18 side. press}. And the seal roll 19 is driven by the movement of the film support roll 18 (cover film 4), and it rotates.

Under such a configuration, as described above, the container film 3 and the cover film 4 are fed between the rolls 18 and 19, and the film 3 and 4 heat between the rolls 18 and 19. By passing in the pressure contact state, the cover film 4 adheres to the back surface side of the container film 3.

In addition, as shown in FIG. 4, in the part corresponding to each part 45 (refer FIG. 3) of the film support roll 18 among the PTP films 6, the slightly bent part 6a is However, since the bent portion 6a serves as a boundary between the PTP sheets 1, the bent portion 6a becomes a cut member 25 so that the bent portion 6a is a range except the bent portion 6a at the time of sheet punching. By punching out the PTP sheet 1 at W, it becomes possible to obtain the PTP sheet 1 without warping in its entirety.

As described in detail above, according to the present embodiment, the film support roll 18 has a substantially octagonal pillar shape having a plurality of flat surfaces 41 orthogonal to its radial direction on its outer circumferential surface. In each of the flat surfaces 41, a pocket bearing recess 43 is provided. Thereby, the container film 3 can be appropriately hanged on the film support roll 18, without applying excessive stress to the pocket part 2 of the container film 3, and the film general part around it. . As a result, since the film general part around the pocket part 2 can be sealed in a flat state, the dent of the pocket part 2, the bending of the film general part between the pocket parts 2, and the cover film 4 which were taken out were carried out. The occurrence of various defects such as wrinkles can be suppressed.

Moreover, according to this embodiment, the continuous sending operation | movement using the film support roll 18 etc. can aim at speed up of a production speed, and can suppress the enlargement of an apparatus.

In addition, in the present embodiment, since the seal roll 19 is cylindrical, for example, both the film support roll 18 and the seal roll 19 are polygonal, and while the flat surfaces of the both are pressed together tightly. As compared with the structure which seals the container film 3 and the cover film 4, it is easy to absorb the assembly error of each roll 18 and 19, etc., and can perform a stable seal at a more uniform pressure. Moreover, only the film support roll 18 side can be replaced without replacing the seal roll 19 side, and it can respond to various varieties, and can improve versatility.

In addition, as for each flat surface 41 of the film support roll 18, the length S in the circumferential direction of the film support roll 18 becomes length corresponding to the sheet formation pitch P of the PTP sheet 1, Therefore, the whole area | region of the PTP sheet 1 can be sealed in a flat state, and the said effect can be made more certain by the PTP sheet 1 unit.

In addition, it is not limited to the description content of the said embodiment, For example, you may carry out as follows. Of course, other application examples and modifications which are not illustrated below are naturally possible.

(a) Although the content is specific about the case where the content is the tablet 5 in the said embodiment, it does not specifically limit about the kind, shape, etc. of the content, For example, even if it is a structure in which food, an electronic component, etc. are filled as the content, good. Of course, the shape, size, etc. of the pocket part 2 formed corresponding to these contents are not limited to the said embodiment, either.

(b) The material of each film 3 and 4 is not limited to the metal material which mainly uses aluminum, You may employ | adopt the thing of other materials, such as a resin material. Even when the container film 3 is formed of a resin material such as PP or PVC, when the shape of the pocket portion 2 is relatively large, the above-described various defects may occur, such as crushing of the pocket portion 2. .

(c) In the said embodiment, the film support roll 18 is made into the substantially octagonal pillar shape. Not only this but other structure may be employ | adopted as long as it is a polygonal column shape with a flat surface. Moreover, you may employ | adopt the structure which the each part 45 rounded instead of the sharp structure of the corner part 45 of the film support roll 18. As shown in FIG. In this way, generation | occurrence | production of the said bending part 6a in the PTP film 6 can be reduced.

(d) In the said embodiment, the inner peripheral side 43a of the pocket support recessed part 43 is formed so that it may orthogonally cross the flat surface 41. As shown in FIG. Not only this but the inner peripheral side 43a of the pocket receiving recessed part 43 is formed along the radial direction of the film receiving roll 18, and may be the structure inclined with respect to the flat surface 41, for example.

(e) It is good also as a structure provided with the heating apparatus in the upstream of the pocket part forming apparatus 14. By setting it as such a structure, the PTP packaging machine 8 not only makes the container film 3 aluminum but heat | fever which is comparatively hard, such as PP and PVC, and has predetermined rigidity. It becomes a packaging machine (combination machine) comprised so that manufacturing also with a plastic resin material is possible. Of course, when forming the container film 3 made from aluminum, a heating apparatus is not used.

(f) In the said embodiment, the length S of each flat surface 41 in the circumferential direction of the film support roll 18 is the sheet formation pitch P of the PTP sheet 1 in the longitudinal direction of the PTP film 6. Although it is set to the length equivalent to one pitch of, the forming range of the flat surface 41 is not limited to this. For example, the length S of each flat surface 41 may be set to the length corresponding to n pitch portion (n is a natural number of two or more) of the sheet formation pitch P of the PTP sheet 1.

Moreover, not corresponding to the PTP sheet unit, the pocket support recesses 43 for one row in the circumferential direction of the film support roll 18 correspond to each pocket support recess 43 in the circumferential direction of the film support roll 18. ) May be formed into a flat surface. However, when the container film 3 consists of a resin material, after the container film 3 and the cover film 4 are adhere | attached by the heating at the time of formation of the pocket part 2, the difference of these heat shrinkage rates is different. {違; Since curling may occur due to a misalignment or the like, the length S of each flat surface 41 is set to a length corresponding to n pitch fraction (n is a natural number of 1 or more) of the sheet formation pitch P of the PTP sheet 1. It is preferable.

(g) In the said embodiment, although the PTP sheet 1 is formed with respect to the width direction (direction of the rotation axis 18a of the film support roll 18) of the PTP film 6 by one sheet, it is this It is good also as a structure in which two or more PTP sheets 1 are formed in the width direction of the PTP film 6, without being limited to this. Of course, in this case, the length of each flat surface 41 in the direction of the rotation axis 18a of the film support roll 18 also corresponds to a plurality of sheets of the PTP sheet 1 (width of the PTP film 6). It has a length.

(h) In the said embodiment, although the angle which the container film 3 conveyed from the upstream of the film support roll 18, and the PTP film 6 conveyed from the downstream makes is perpendicular, it is not limited to this. For example, as shown to Fig.6 (a), the angle (beta) which the container film 3 conveyed from the upstream of the film support roll 18 and the PTP film 6 conveyed from the downstream side makes an acute angle. It may be set to {{}}, and may be set to an obtuse angle {{}}, as shown in FIG.

In the case where the container film 3 is made of aluminum as in the above-described embodiment, it is preferable to set the angle β to an obtuse angle as shown in FIG. Do. On the other hand, when the container film 3 is made of resin, the angle β is set at an acute angle as shown in Fig. 6A in order to prevent the occurrence of curl due to heating at the time of forming the pocket portion 2. And it is more preferable to lengthen the contact time of the film support roll 18 and the container film 3, and to make a cooling rate faster.
