Description
Technical Field
The present invention relates to a blister packaging machine and a method for manufacturing a blister package.
Background
In recent years, as packaging containers for pharmaceuticals, cosmetics, and the like, there have been widely used, for example, food such as jelly, jam, yogurt, milk for coffee, gum syrup (gum syrup), cream, and the like, and for example, a tear-open type blister package (blister pack) such as a single package (portion pack), a folding-open type blister package such as DISPEN PAK (registered trademark), and the like.
Such a blister package is composed of a container film having a bag portion formed therein for filling contents, and a cover film attached to the container film so as to seal the opening side of the bag portion.
In general, blister packages will be manufactured by the following procedure: a bag forming step of forming a bag while conveying the band-shaped container film; a filling step of filling the bag portion with a content; a sealing step of attaching a cover film to the container film so as to seal the opening side of the bag portion; and a die cutting step of die cutting a blister package to be a final product from a strip-shaped package (strip-shaped blister film) to which the two films are attached (for example, refer to patent document 1).

Disclosure of Invention
Problems to be solved by the invention
However, there is a problem that the content is adhered to a general portion of the container film outside the bag portion due to, for example, the overflow of the content from the bag portion in the filling process, or the falling of the content from the bag portion in the conveyance process until the subsequent sealing process, depending on the volume or type of the content filled in the bag portion.
In this case, in the subsequent sealing step, the band-shaped package produced by sealing the peripheral edge portion of the bag portion with the cover film is transported to the subsequent punching step while the content is held between the unsealed portion between the unsealed container film general portion and the cover film (see fig. 4).
The die cutting device used in the die cutting step includes an upper die disposed above the band-shaped package and a lower die disposed below the band-shaped package, and the two dies are configured to be movable relatively in a direction approaching each other or a direction separating from each other along the up-down direction.
Generally, the upper die is provided with: a punch for punching a blister pack from a strip-shaped package, a punch holder holding the punch, and a stripper for pressing the strip-shaped package from above when punching the blister pack; and the lower die is provided with: a die having an insertion hole into which a punch is inserted when punching a blister package.
In this configuration, the punching device is configured to punch the blister package by lowering the upper die (punch holder) and raising the lower die (die) and pressing the punch into the insertion hole of the die while pressing the strip-shaped package die with the stripper.
Therefore, when the blister package is die-cut in the die-cutting process, there is a risk that the content held in the unsealed portion of the tape-shaped package adheres to the die-cutting device (punch, die, or the like).
The content is left alone as it is attached to the die-cutting device, and there is a risk of various problems occurring due to deterioration of the attached content, etc., which may cause problems in hygiene, adhesion of the content, corrosion of the die-cutting device, etc., and failure of the die-cutting device. Thus, cleaning work of the punching device has been frequently performed.
The present invention has been made in view of the above circumstances and has an object to provide a blister packaging machine and a method for manufacturing a blister package capable of suppressing adhesion of contents and the like.
Means for solving the problems
The following will describe each means item applied to solve the above-described problems. The specific action and efficacy are noted in the corresponding means as needed.
Means 1. A blister packaging machine for manufacturing a blister package, the blister package comprising: a container film having a bag portion for filling the contents; and a cover film attached to the container film so as to close the bag portion,
the blister packaging machine is characterized by comprising:
a bag forming mechanism for forming the bag on the container film while conveying the container film in a belt shape;
a filling mechanism for filling the bag portion with the content;
a sealing mechanism for attaching the band-shaped cover film to the container film filled with the content in the bag portion so as to close the bag portion;
a punching mechanism for punching the blister package from a band-shaped package (band-shaped blister film) having the cover film attached to the container film; and
and a washing water supply mechanism for supplying washing water to the upper surface of the band-shaped package body with the cover film mounted on the container film before punching the blister package.
By the means 1, the blister pack is punched in a state in which the washing water is deposited on the strip-shaped package by supplying the washing water to the upper surface of the strip-shaped package before punching the blister pack.
Thus, the blister package is punched, and the contents held in the unsealed portion of the strip-shaped package or the contents adhering to the punching mechanism (punch, die, etc.) can be washed by the washing water flowing down from the upper surface side of the strip-shaped package.
As a result, the content is less likely to adhere to the die-cutting mechanism, and various problems caused by the adhesion of the content can be suppressed. Further, the frequency of cleaning operations and the like of the punching mechanism can be reduced.
The blister pack machine according to the means 1, wherein the washing water supply means is provided between the sealing means and the punching means.
The washing water supply mechanism is arranged at the same position as the punching mechanism or integrated with the punching mechanism, so that the structure of the packaging machine is complicated.
In contrast, by the means 2, the washing water is supplied to the band-shaped package on the upstream side of the die-cutting mechanism, and the washing water can be transported toward the die-cutting mechanism in accordance with the transportation of the band-shaped package. Further, the blister package can be die-cut in a state where the washing water is deposited on the tape-shaped package. As a result, the washing water supply mechanism can be provided without complicating the constitution of the packing machine.
Means 3. The blister packaging machine according to means 1 or 2, characterized by comprising a reverse flow restricting mechanism that restricts the flow of the washing water on the strip-shaped package toward the sealing mechanism side.
In general, in the punching step, an upper die and a lower die of a punching mechanism are clamped before punching of a blister package, and a band-shaped package is gripped by the upper die and the lower die (a stripper and a die).
Therefore, the washing water on the tape-shaped package is pushed away by the upper die (stripper) or the like, and there is a problem of the sealing mechanism facing the upstream side.
In particular, in the configuration of the means 2, the belt-shaped package is conveyed toward the punching mechanism in a state where the washing water is deposited, and in this case, even if the belt-shaped package itself is stopped, the washing water deposited on the belt-shaped package is strongly directed toward the punching mechanism side (downstream side) by inertia. Further, since the upper die (stripper) is clamped, the flow of the washing water is blocked, and a part of the washing water is rebounded in the opposite direction (upstream side), which causes a problem of the sealing mechanism.
When the washing water flows toward the sealing mechanism in this way, the sealing mechanism itself or the sealing portion of the package is cooled, and there is a risk of occurrence of poor sealing.
In contrast, by providing the means 3 with the reverse flow restricting means, the flow of the washing water to the sealing means side can be restricted, and the occurrence of the above-described problem can be prevented.
Means 4. The blister packaging machine according to means 3, wherein the reverse flow restricting means is an air injecting means provided between the sealing means and the washing water supplying means, and injects air (gas such as air) from an upstream side of the washing water supplying means toward the washing water on the strip-shaped package.
By the means 4, the reverse flow of the washing water deposited on the belt-shaped package can be restricted without contacting the package. Thus, it is expected to suppress degradation of product quality.
Means 5. A method for manufacturing a blister pack, the blister pack comprising: a container film having a bag portion for filling the contents; and a cover film attached to the container film so as to close the bag portion,
the method for manufacturing the blister package is characterized by comprising the following steps:
a bag forming step of forming the bag on the container film while conveying the container film in a belt shape;
a filling step of filling the bag portion with the content;
a sealing step of attaching a band-shaped cover film to the container film in which the bag portion is filled with the content so as to close the bag portion;
a die cutting step of die cutting the blister package from a strip-shaped package (strip-shaped blister film) having the cover film attached to the container film; and
and a washing water supply step of supplying washing water to the upper surface of the band-shaped package in a step subsequent to the sealing step and a step preceding to the punching mechanism.
By means 5 described above, the same operational effects as those of means 1 described above can be obtained.

Detailed Description
Hereinafter, an embodiment will be described with reference to the drawings. First, the blister package 1 to be manufactured will be described in detail.
As shown in fig. 2 (a) and (b), the blister pack 1 of the present embodiment includes: a container film 3 having one bag portion 2; and a cover film 4 attached to the container film 3 so as to close the opening of the bag portion 2.
The bag portion 2 is filled with a content 5 (see fig. 2 (b) and the like). Examples of the content 5 include: jelly, jam, yogurt, milk for coffee, gelatinous syrup, butter, etc. Of course, the bag 2 may be filled with other foods, not limited to the illustrated foods. The bag 2 may be filled with the contents of a medicine, a cosmetic, or the like, not limited to food.
The container film 3 of the present embodiment is made of a thermoplastic resin material such as PVC (polyvinyl chloride). Further, a flange portion 3a is formed on the container film 3, and the flange portion 3a is formed so as to extend outward from the peripheral edge of the opening portion of the bag portion 2.
On the other hand, the cover film 4 is formed by laminating another kind of synthetic resin film on an aluminum vapor deposited synthetic resin film, and is attached so as to be peelable from the container film 3 (flange portion 3 a).
In the blister package 1 of the present embodiment, the container film 3 (flange portion 3 a) and the lid film 4 are not adhered to each other at one portion of the peripheral edge portion thereof. Thus, the cover film 4 here is formed as a pinching portion 4a when the blister package 1 is opened.
Here, the opening sequence of the blister package 1 will be described. First, the container film 3 is held by one hand, and the pinching portion 4a of the cover film 4 is pinched by the other hand. Then, the lid film 4 is peeled off from the container film 3 while pinching the pinching portion 4a. This completes the opening of the blister package 1, and the contents 5 filled in the bag portion 2 can be taken out.
As will be described later, the blister pack 1 according to the present embodiment is manufactured by the following steps: the blister package 1 as a final product is die-cut from a blister film 35 (see fig. 3) as a strip-shaped package body constituted by attaching the strip-shaped container film 3 and the strip-shaped cover film 4. Further, in fig. 3, a scattering dot pattern is added to a portion of the blister film 35 for convenience.
Next, the constitution of the blister packaging machine 10 for manufacturing the blister package 1 will be described.
As shown in fig. 1, in the blister packaging machine 10, a band-shaped container film 3 drawn from a roll-shaped material is intermittently conveyed in a downstream direction by a chain nip conveyor (chain clipped conveyor) 11 or the like. The clip (clip) portion 11a (see fig. 3) of the chain clip conveyor 11 is configured to hold both ends in the film width direction (Y direction) of the container film 3 or the blister film 35.
On the downstream side of the roll of container film 3, first, a heating device 12 and a bag forming device 13 are provided. The heating device 12 and the bag forming device 13 constitute a bag forming mechanism according to the present embodiment.
The heating device 12 includes an upper die 12a and a lower die 12b which sandwich the container film 3 and are arranged vertically, and is configured to be capable of locally heating the formation range of the bag portion 2 of the container film 3.
The bag forming apparatus 13 includes an upper die 13a and a lower die 13b, and the upper die 13a has a pin (not shown) having a shape substantially similar to that of the bag 2 and smaller than that of the bag; the lower die 13b has a molding recess (not shown) corresponding to the shape of the bag portion 2.
Then, first, the upper die 13a and the lower die 13b are relatively moved in the approaching direction to each other in a state where the container film 3 is heated by the heating device 12 and is formed to be relatively soft. Next, the pins protrude from the upper die 13a to form the approximate shape of the bag portion 2. Finally, the bag portion 2 is formed at a predetermined position of the container film 3 by blowing air from the upper die 13a and pressing the container film 3 against the forming concave portion of the lower die 13 b. The formation of the bag 2 is performed during the interval (interval) between the conveyance operations of the container film 3.
A filling device 14 as a filling mechanism for filling the bag 2 with the content 5 is provided downstream of the bag forming device 13.
On the other hand, the roll of cover film 4 formed in a band shape is wound in a roll shape separately from the container film 3. The cover film 4 drawn out from the roll is guided to a receiving roller 15 provided on the downstream side of the filling device 14. The cover film 4 is guided to the receiving roller 15, and is formed to be stacked on the container film 3 so as to block the bag 2.
A sealing device 16 as a sealing mechanism is provided on the downstream side of the receiving roller 15. The sealing device 16 includes an upper die 16a and a lower die 16b, and both dies 16a and 16b are configured to be movable up and down and to be pressure-contacted, the lower surface of the upper die 16a itself is heated to a predetermined sealing temperature, and the lower die 16b is formed with a recess (symbol omitted) corresponding to the bag portion 2.
Then, the container film 3 and the cover film 4 are fed between the upper die 16a and the lower die 16b, and the two films 3 and 4 are pressure-bonded by the two dies 16a and 16b, whereby the cover film 4 is attached to the container film 3. Thereby, the strip-shaped blister film 35 is produced in a state where the bag portion 2 filled with the contents 5 is sealed with the cover film 4. However, in the present embodiment, only the sealing portion 4b (see the diagonal line portion in fig. 3) to which the cover film 4 is attached (sealed) is formed at the flange portion 3a corresponding to the periphery of the bag portion 2, and the unsealed portion 4c to which the cover film 4 is not attached is formed at other positions.
An air injection device 17 as a backflow restriction mechanism (air injection mechanism) and a washing water supply device 18 as a washing water supply mechanism are provided downstream of the sealing device 16. Hereinafter, the air injection device 17 and the washing water supply device 18 will be described in detail. However, for convenience, the washing water supply device 18 will be described.
The washing water supply device 18 is provided upstream of a die-cutting device 19 described later for supplying washing water H on the upper surface (the cover film 4 side) of the blister film 35 before die-cutting the blister package 1.
As shown in fig. 4, the washing water supply device 18 includes a washing water supply pipe 18a and a plurality of water discharge ports (water discharge ports) 18b, the washing water supply pipe 18a is connected to a not-shown washing water supply source extending in the film width direction (the inner direction in fig. 4) of the blister film 35, the plurality of water discharge ports (water discharge ports) 18b are provided at predetermined intervals in the extending direction of the washing water supply pipe 18a, and the washing water H supplied from the washing water supply source can be supplied substantially uniformly to substantially the entire film width direction on the upper surface of the blister film 35 through the washing water supply pipe 18a and the water discharge ports 18 b.
The water discharge ports 18b of the present embodiment are each slightly inclined downward toward the downstream side in the film conveying direction (X direction) than the vertically downward position, and the washing water H is configured to be discharged (spouted) toward the downstream side in the film conveying direction on the blister film 35. With this configuration, the flow of the washing water H on the blister film 35 toward the sealing device 16 can be restricted. That is, such a configuration may function as a backflow regulating mechanism in the present embodiment.
The air jetting device 17 jets air (gas such as air) E toward the washing water H supplied from the washing water supply device 18 to the upper surface of the blister film 35, restricts the flow of the washing water H to the sealing device 16 side, and is provided between the sealing device 16 and the washing water supply device 18.
The air jet device 17 includes an air supply pipe 17a and a plurality of air jet nozzles 17b, the air supply pipe 17a is connected to an unillustrated air blower (air blower) extending in the film width direction of the blister film 35, the plurality of air jet nozzles 17b are provided at predetermined intervals in the extending direction of the air supply pipe 17a, and the air E supplied from the air blower can be jetted substantially uniformly over substantially the entire film width direction on the upper surface of the blister film 35 through the air supply pipe 17a and the air jet nozzles 17 b.
The air-blowing nozzles 17b of the present embodiment are each configured to spray the air E on the blister film 35 so as to be directed toward the downstream side in the film conveying direction (X direction) while being slightly inclined downward toward the downstream side in the film conveying direction than the vertically downward position.

Below the punching device 19, a conveyor 21 is provided, which corresponds to the position where each blister pack 1 punched from the blister film 35 falls. By such a conveyor 21, the blister pack 1 is transferred to a product bin 22.
A receiving tray 23 as a washing water storage means for receiving the washing water H flowing down from the punching device 19 together with the blister pack 1 when the blister pack 1 is punched is provided below the conveyor 21.
A cutting device 25 for cutting a scrap (scrap) portion 35a remaining after die cutting the blister package 1 is disposed downstream of the die cutting device 19. Then, the scrap portion 35a is cut to a predetermined size by the cutting device 25, and is stored in the scrap box 27.
The outline of the blister packaging machine 10 is as described above, and the punching device 19 will be described in detail below with reference to fig. 4 and 5.
The punching device 19 includes an upper die 38 disposed above the blister film 35 (on the cover film 4 side) that is conveyed in the substantially horizontal direction (X direction), a lower die 39 disposed below the blister film 35 (on the container film 3 side), and a driving mechanism, not shown, that drives the two dies 38, 39. As the driving mechanism, a motor, a fluid pressure cylinder, a cam transmission mechanism, or the like may be employed. Thus, the dies 38 and 39 are configured to be relatively movable in the up-down direction (Z direction) in the direction approaching each other or in the direction separating from each other.
The upper die 38 includes: a punch 41 for punching the blister pack 1 from the blister film 35, a punch holder (punch holder) 42 for holding the punch, and a stripper 43 for pressing the blister film 35 from above when punching the blister pack 1.
The stripper 43 is mounted so as to be relatively displaceable in the up-down direction with respect to the punch holder 40 by a coil spring 44 as an elastic mechanism (elastic member), and is energized (biased) downward.
The lower die 39 is provided with a die (die) 45 formed with an insertion hole 45a into which the punch 41 is inserted when punching the blister pack 1.
The procedure for producing the blister package 1 by the blister packaging machine 10 configured as described above and the effects thereof will be described mainly with respect to the main steps after forming the blister film 35 for filling and sealing the contents 5 in the bag portion 2.
The blister film 35 formed by the bag forming step of forming the bag 2, the filling step of filling the bag 2 with the content 5, the sealing step of attaching the cover film 4 to the container film 3, and the like is transported to the air jetting device 17 and the washing water supply device 18, and the washing water supply step is performed.
In addition, in the process of conveying the content 5 from the bag portion 2 to the subsequent sealing step after the overflow of the content 5 from the bag portion 2, when the content 5 adheres to the general portion of the container film 3 outside the bag portion 2, the blister film 35 is conveyed to the next washing water supply step while the content 5 is held between the unsealed portion 4c of the lid film 4 and the general portion of the container film 3 that is not sealed in the subsequent sealing step (see fig. 4).
In the washing water supply step, the washing water H from the washing water supply device 18 is supplied to the upper surface of the blister film 35 before punching the blister pack 1.
Further, although not shown, when the washing water H is supplied to the upper surface of the blister film 35 holding both ends in the film width direction by the nip portion 11a, the blister film 35 is recessed in the vicinity of the center in the film width direction due to the weight of the washing water H, and is gently bent in the film width direction, so that the washing water H is less likely to flow down from both ends in the film width direction.
The washing water H is supplied from the washing water supply device 18 in this way, and the air E is sprayed from the air spraying device 17 located on the upstream side of the washing water supply device 18 toward the washing water H on the upper surface of the blister film 35.
However, in the present embodiment, the supply of the washing water H or the ejection of the air E is not intermittently performed in accordance with the intermittent operation of the blister film 35, but is constantly performed continuously. Of course, the supply of the washing water H or the ejection of the air E may be intermittently performed in accordance with the intermittent operation of the blister film 35.
Thereafter, the blister film 35 is conveyed to the punching device 19, and subjected to a punching process. When the blister film 35 is conveyed to the punching device 19, the washing water H supplied to the blister film 35 by the washing water supply device 18 located upstream of the punching device 19 is also conveyed to the punching device 19.
In the punching device 19, normally, that is, during conveyance of the blister film 35, the upper die 38 (punch 41, punch holder 42, stripper 43) is located at a standby position separated upward from the blister film 35, and the lower die 39 (die 45) is located at a standby position separated downward from the blister film 35.
When the intermittently conveyed blister film 35 stops at a predetermined position, the upper die 38 is lowered, the lower die 39 is raised, and the blister film 35 is pressed against the die 45 by the stripper 43 (see fig. 5 (a)).
At this time, the body of the blister film 35 is stopped, but the washing water H deposited thereon is strongly directed toward the punching device 19 side by inertia. Further, the stripper 43 of the blister film 35 is pressed, and the flow of the washing water H is blocked, and at the same time, a part of the washing water H is rebounded in the opposite direction and directed to the upstream side. In the present embodiment, the air E ejected from the air ejection device 17 restricts the arrival of the washing water H toward the upstream side at the sealing device 16.
Thereafter, the punch 41 is lowered, and the washing water H is deposited on the blister film 35, so that the punch 41 gradually enters the insertion hole 45a of the die 45 [ see fig. 5 (b) ]. Then, the punch 41 is pushed into the insertion hole 45a, whereby the blister pack 1 is punched out by the blister film 35 (see fig. 5 (c)). The punched blister package 1 falls into the insertion hole 45a, is guided to the conveyor 21, and is transferred to the finished product magazine 22.
Meanwhile, if there are the contents 5 held by the unsealed portion 4c of the blister film 35 or the contents 5 adhering to the punching device 19 (the punch 41, the die 45, or the like), these contents 5 are washed away by the washing water H flowing down from the upper surface side of the blister film 35.
Thereafter, the upper die 38 and the lower die 39 are separated from the blister film 35, and the washing water H remaining on the blister film 35 flows down through the punching holes 35b and the like formed in the blister film 35 after punching the blister package 1, passes around the die 45 or through the insertion holes 45a while flushing the upper surface of the die 45, flows down again, passes along with the washing water H flowing down at the time of punching the blister package 1, and is collected on the receiving tray 23 by the side of the conveyor 21 and the like.
Thus, when the punching process of the blister package 1 is completed, the manufacture of the blister package 1 is completed.
As described above in detail, according to the present embodiment, the washing water supply device 18 is provided, and the washing water H is supplied to the upper surface of the blister film 35 before the blister package 1 is punched, whereby the blister package 1 can be punched in a state where the washing water H is deposited on the blister film 35.
Accordingly, the washing water H flowing down from the upper surface side of the blister film 35 can wash away the content 5 held in the unsealed portion 4c of the blister film 35 or the content 5 adhering to the punching device 19 (such as the punch 41 or the die 45) simultaneously with punching the blister package 1.
As a result, the content 5 is less likely to adhere to the die-cutting device 19, and various problems caused by the adhesion of the content 5 can be suppressed. Further, the frequency of cleaning operations and the like of the die cutting device 19 can be reduced.
In the present embodiment, the washing water supply device 18 is provided upstream of the punching device 19 (between the sealing device 16 and the punching device 19). Thereby, the washing water H is supplied to the blister film 35 on the upstream side of the die-cutting device 19, and the washing water H can be transported toward the die-cutting device 19 in association with the transportation of the blister film 35. As a result, the washing water supply means 18 can be provided without complicating the constitution of the blister pack machine 10.
Next, in the present embodiment, a reverse flow restricting mechanism for restricting the flow of the washing water H on the blister film 35 to the sealing device 16 side is provided. Specifically, the air jetting device 17 jetting air E toward the washing water H on the blister film 35 is provided on the upstream side of the washing water supply device 18. As a result, the risk of poor sealing due to cooling of the sealing portion of the sealing device 16 or the blister film 35 can be reduced.
The present invention is not limited to the description of the above embodiments, and may be implemented, for example, as follows. Naturally, other application examples and modification examples not illustrated below may be implemented.
(a) The constitution of the blister pack 1 to be manufactured is not limited to the above embodiment.
For example, the blister pack 1 of the above embodiment is configured to have one pocket 2, but the present invention is not limited thereto, and a plurality of pockets may be formed in one blister pack. The size, shape, etc. of the blister pack 1 or the pouch portion 2 are not limited to the above embodiment, and may be configured differently.
In the above embodiment, the tear-open type blister package 1 is configured such that the container film 3 (flange portion 3 a) and a part of the lid film 4 are not adhered to each other and the pinch portion 4a is formed at the time of opening, but the present invention is not limited to this, and the pinch portion 4a may not be formed by removing a portion where the container film 3 (flange portion 3 a) and the lid film 4 are not adhered to each other. Further, a breaking line such as a half-cut line may be formed in advance in a part of the flange portion 3a, and the flange portion 3a may be bent along the breaking line to break a part of the outer edge portion at the time of unsealing, and the part may be pinched to peel off the cover film 4.
Further, the package is not limited to the tear-open type, and a fold-open type package such as DISPEN PAK (registered trademark) may be used.
(b) The material of the container film 3 or the cover film 4 is not limited to the above embodiment, and may have a different structure.
For example, in the above embodiment, the container film 3 is formed of PVC, but is not limited thereto, and may be formed of a resin material such as CPP (polypropylene without elongation) or PET, or may be formed of a metal material such as aluminum.
(c) The constitution of the blister film 35 is not limited to the above embodiment. For example, in the above-described embodiment, the blister pack 1 is configured to be manufactured in total of four in the film conveyance direction and the film width direction of the blister film 35, but it may be configured to be manufactured in one or three or more in the film conveyance direction or the film width direction of the blister film 35 instead.
(d) The configuration of the washing water supply mechanism is not limited to the washing water supply device 18 of the above embodiment, and may be different.
For example, in the above embodiment, the washing water supply device 18 is provided on the upstream side of the punching device 19 (between the sealing device 16 and the punching device 19). However, the present invention is not limited thereto, and the washing water supply mechanism may be provided at the same position as the die-cutting device 19, or may be provided integrally with the die-cutting device 19.
In the above embodiment, the water discharge ports 18b are each slightly inclined downward toward the downstream side in the film conveying direction, as compared with the vertically downward position, and the washing water H is so configured as to be discharged toward the downstream side in the film conveying direction on the blister film 35. However, the drain openings 18b may be configured to drain vertically downward at vertically downward positions.
(e) As in the above embodiment, the configuration of the reverse flow restricting mechanism is not limited to: the air jetting device 17 (air jetting means) jetting the air E from the upstream side of the washing water supply device 18 toward the washing water H on the blister film 35, or the structure in which the washing water H is discharged obliquely downward from the water discharge port 18b of the washing water supply device 18 toward the downstream side in the film conveying direction may be employed.
For example, as shown in fig. 6, an elastic member such as a rubber sheet 80 may be brought into contact with the upper surface of the blister film 35 on the upstream side of the washing water supply device 18 to restrict the flow of the washing water H toward the sealing device 16, instead of the air injection device 17.
As shown in fig. 7, at least one section between the sealing device 16 and the punching device 19 may be configured such that the conveyance path of the blister film 35 (the guide path of the chain portion of the chain conveyor 11) is inclined by guide gears 91, 92 (or guide rollers) or the like so that the downstream side is lower than the upstream side, thereby restricting the flow of the washing water H toward the sealing device 16.
