Description

Bubble drum packaging machine

The present invention relates to a blister packaging machine for manufacturing a blister sheet containing contents such as tablets.

PTP (Press Through Package) sheets are known as bubble sheets generally used in fields such as pharmaceuticals and foods. The PTP sheet is provided with: a container film (film) having a pocket portion for storing contents such as tablets; and a cover film (cover film) attached to the container film to seal the opening side of the pocket portion. .

PTP tablets are manufactured using a PTP packaging machine, which is a type of bubble packaging machine. The PTP packaging machine is equipped with bag forming means, filling means, sealing means and punching means, etc. The bag forming means is attached to the belt-shaped container film to form the bag. The filling method is to fill the contents into the bag. The sealing means is to attach a film to the container film so as to block the opening of the bag. The punching method is a strip-shaped PTP film formed by die-cutting and coating the container film. PTP sheets are obtained by die-cutting the PTP film.

In addition, the portion of the PTP film located on the downstream side of the punching means, that is, the scrap portion (for example, the unnecessary portion left after punching) is cut by a predetermined scrap cutting means. In recent years, an apparatus integrating a punching means and a scrap cutting means has been proposed (see, for example, Patent Document 1 below).

The apparatus of Patent Document 1 is equipped with a head, which has a cutter for sheet punching and is arranged downstream of the cutter for sheet punching in the conveyance direction of the PTP film and further than the sheet punching cutter. a scrap cutting knife that protrudes sufficiently toward the PTP film side; and a base that has a punching hole (opening) through which the sheet punching knife can be inserted and is disposed on The PTP film bag is sandwiched between the aforementioned cutter head. In this device, by adjusting the movement amount of the blade toward the substrate side, it is possible to selectively punch the PTP film and cut the waste portion, or cut only the waste portion without punching the PTP film.

More specifically, the cutter head is moved so that the sheet punching cutter is inserted into the punching hole, whereby the PTP film is punched out by the sheet punching cutter and the scrap cutting cutter is used. The knife cuts off the scrap part. On the other hand, by moving the cutter head to a position where the scrap cutting knife penetrates the PTP film without inserting the punching knife into the punching hole, only the scrap is processed without punching the PTP film. Partial cutting. [Prior technical literature] [Patent Document]

[Problem to be solved by the invention]

In addition, in the above-mentioned apparatus, as shown in FIG. 16 (for convenience of illustration, the PTP film 6 is shown thicker than actually in FIG. 16 ), the PTP film 6 is conveyed along the surface of the base 101 . Therefore, as shown in FIG. 17 , among the portions of the PTP film 6 (scrap portion 7 ) where the holes 8 (holes corresponding to the PTP sheet 1 ) are formed, particularly the portion facing forward in the forward direction is caught in the base 101 Among the edge portions corresponding to the punched holes 102 , there is particularly a downstream edge portion 103 located downstream in the conveyance direction of the PTP film 6 . When jamming occurs as described above, the manufacturing of the PTP sheet 1 may fail.

The present invention was developed in view of the above situation, and aims to provide a blister packaging machine that can more reliably prevent the blister membrane from getting stuck on the die-cut blister membrane. [Means used to solve problems]

Below, each of the best means to solve the above problems will be explained item by item. In addition, if necessary, annotate the corresponding means with their unique effects.

Means 1. A bubble packaging machine that manufactures bubble sheets by punching out a strip-shaped bubble membrane in units of sheets, wherein the strip-shaped bubble membrane is a strip-shaped container containing contents in a bag portion. The film is formed by attaching a strip-shaped covering film to seal the bag part, and is characterized by: The transporting means is to transport the aforementioned tympanic membrane intermittently; and The slice cutting means is to cut off the temporarily stopped tympanic membrane; The sheet cutting means includes a first component and a second component located at a position sandwiching the tympanic membrane; The aforementioned first component consists of: The sheet punching knife is a blade having a shape corresponding to the outer edge shape of the aforementioned bubble sheet; and The waste material cutting knife is provided on the downstream side of the conveying direction of the aforementioned bubble membrane than the aforementioned sheet punching knife; The aforementioned second component includes: The sheet punching support part is configured to transport the bubble membrane along a flat surface, and has a shape corresponding to the outer edge shape of the bubble sheet and a punching hole opened on the surface; and The scrap cutting support part is provided on the downstream side in the conveying direction than the sheet punching support part; It is configured that the sheet punching blade is inserted into the sheet punching blade by moving the first component part from the retracted position in which the sheet punching blade and the scrap cutting blade are separated from the bubble membrane to two predetermined cutting positions. The bubble membrane is punched through the punching hole by the sheet punching knife and the sheet punching support part, and the position in the bubble membrane is cut by the scrap cutting blade and the scrap cutting support part. A scrap portion located downstream of the sheet punching blade in the conveying direction; On the other hand, the first component is moved from the retracted position to a predetermined cutting position, and the scrap cutting blade and the scrap cutting support part are used without cutting the bubble membrane. Cut off the aforementioned waste portion; A guide means is provided between the sheet punching support part and the scrap cutting support part in the second component part to guide the scrap part through a path close to the scrap cutting knife, at least during the first step. A component is disposed in the retracted position so that the bubble membrane floats from a downstream edge portion located downstream in the conveyance direction among the edge portions of the sheet punching support portion corresponding to the punching hole. status; At least the portion of the scrap cutting support portion that cooperates with the scrap cutting knife to cut the scrap portion is farther toward the scrap cutting portion than the surface of the sheet punching support portion along the moving direction of the first component. The broken blade side protrudes.

According to the above-mentioned means 1, the scrap portion is guided by the guide means through a path close to the scrap cutting blade, and at least in a state where the first component is arranged in the retracted position, the bubble membrane is formed from the downstream side of the sheet punching support portion The edge is floating (leaving away). Therefore, the bubble membrane can be conveyed in a state where it floats from the downstream edge portion. Therefore, it is possible to effectively suppress the occurrence of the blister membrane catching on the downstream edge portion where there is a concern that the blister membrane may get stuck, and to more reliably prevent the blister membrane from getting stuck on the sheet punching support part (a device for punching the blister membrane). . Thereby, the bubble membrane can be conveyed more smoothly, and the operational stability of the device can be improved.

In addition, the portion of the scrap cutting support portion that cooperates with the scrap cutting blade to cut the scrap portion protrudes toward the scrap cutting blade side from the surface of the sheet punching support portion. Therefore, even if the first component is formed in such a manner that the scrap cutting blade does not protrude slightly or not at all from the sheet punching blade in the moving direction of the first component, the first component is disposed at one cutting position (only cutting When cutting the scrap part), it is still possible to more reliably prevent the sheet punching knife from contacting the bubble tympanic membrane. Thereby, while miniaturizing the first component part, it is possible to stably cut only the scrap part by moving the first component part to one cutting position. In addition, the degree of design freedom regarding the positional relationship between the scrap cutting blade and the sheet punching blade can be further improved.

Means 2. The blister packaging machine of means 1, wherein the first component has a pressing part capable of sandwiching the bubble membrane and the surface of the sheet die-cut support part and having a predetermined buffering means; When the first component part moves from the retracted position to the two cutting positions, the pressing part and the sheet punching part are configured to cut the supporting part before the sheet punching blade contacts the bubble membrane. The surface clamps the bleb membrane, and after clamping the bleb membrane, the buffering means is used to avoid hindering the movement of the first component to the two cutting positions.

According to the above means 2, when the first component is moved from the retracted position to the two cutting positions in order to punch the blister membrane, the sheet punching blade is not in contact with the blister membrane (before reaching the two cutting positions). The surface of the die-cut supporting part and the pressing part sandwich the tympanic membrane. Thereby, the bubble membrane originally raised from the surface of the sheet punching support part by the guide means comes into contact with the surface of the sheet punching support part. In addition, in this state, the first component moves to two cutting positions, thereby punching out the tympanic membrane. Therefore, it is possible to more reliably prevent the punching position from being shifted than by directly punching the bubble membrane in a state where it floats from the surface of the sheet punching support portion. As a result, the product quality of the produced bubble sheet can be improved.

In addition, the bubble membrane can be clamped by the pressing part before the sheet punching blade contacts the bubble membrane, and the buffering means provided by the pressing part can also allow further movement of the first component after clamping. Move.

Means 3. The blister packaging machine of means 2, wherein when the first component moves from the retreat position to the two cutting positions, the waste material is cut before the pressing part contacts the bubble membrane. The cutting blade and the scrap cutting support part cut the scrap part.

According to the above-mentioned means 3, when the scrap portion is cut, no force in a direction that interferes with the movement of the first component is exerted from the pressing portion. Therefore, it is possible to suppress an increase in the load (moment force, etc.) applied to the driving means (eg, motor, etc.) for moving the first component.

In addition, it may be configured such that "when the first component part moves from the retracted position to the two cutting positions, before the pressing part clamps the bubble membrane with the surface of the sheet punching support part, , the scrap portion is cut by the scrap cutting blade and the scrap cutting support portion." In this configuration, it is also possible to suppress an increase in the load applied to the driving means for moving the first component.

Means 4. The blister packaging machine according to any one of means 1 to 3, wherein the scrap cutting knife is configured not to cut the scrap further than the sheet punching knife in the moving direction of the first component part. The support portion side protrudes.

According to the above-mentioned means 4, the size of the first component in the moving direction can be further reduced. This makes it possible to more reliably achieve downsizing of the device. In addition, it is possible to more effectively suppress increases in various costs.

Means 5. The blister packaging machine according to any one of means 1 to 4, wherein the guide means is an inclined surface that guides the waste portion by sliding the waste portion.

According to the above means 5, the guide means is a simple inclined surface, so the structure of the guide means can be simplified. This makes it possible to more effectively suppress increases in various costs.

Means 6. The blister packaging machine of means 5, wherein the angle θ1 of the smaller angle among the angles formed by the inclined surface with respect to the imaginary surface including the sheet punching support part is 10° or more and 20° or less. .

According to the above-mentioned means 6, the angle θ1 is configured to be 10° or more, so that the tympanic membrane can be lifted up from the downstream edge portion more reliably.

On the other hand, since the angle θ1 is configured to be 20° or less, it is possible to more reliably prevent the scrap cutting support portion from excessively protruding (height) from the surface (imaginary surface) of the sheet punching support portion. Therefore, it is possible to more reliably prevent the stroke of the first component when moving from the retreat position to the two cutting positions compared to the stroke of the first component when moving from the retreat position to the one cutting position. The amount increases extremely. Thereby, it is possible to more effectively reduce the size of the device, and to more effectively suppress an increase in the load applied to the driving means (eg, motor, etc.) for moving the first component.

Means 7. The bubble packaging machine according to means 5 or 6, wherein a cross section passing through the downstream edge portion is orthogonal to an imaginary plane including the surface of the sheet die-cut support portion and parallel to the conveyance direction of the bubble film. Among the angles formed by an imaginary line extending from the most downstream portion of the inclined surface in the conveyance direction of the bubble membrane to the downstream edge portion with respect to the imaginary surface, the smaller angle θ2 is 5°. Above 20° below.

According to the above-mentioned means 7, the angle θ2 is configured to be 5° or more, so that the bubble membrane can be lifted up from the downstream edge portion more reliably.

On the other hand, since the angle θ2 is configured to be 20° or less, it is possible to more reliably prevent the scrap cutting support portion from being excessively protruded (height) relative to the surface (imaginary surface) of the sheet punching support portion. Thereby, the stroke amount of the first component when moving from the retreat position to the two cutting positions can be made small. Therefore, it is possible to more reliably achieve downsizing of the device, and to more effectively suppress an increase in load applied to a driving means (for example, a motor, etc.) for moving the first component.

Means 8. The blister packaging machine according to any one of means 5 to 7, wherein the height H of the scrap cutting support portion relative to the surface of the sheet punching support portion along the moving direction of the first component is: Above 3mm and below 8mm.

According to the above means 8, the height H is configured to be 3 mm or more, so that the bubble membrane can be more reliably raised from the downstream edge portion.

On the other hand, the height H is configured to be 8 mm or less. As a result, the stroke amount of the first component when moving from the retreat position to the two cutting positions can be made small. This makes it possible to more reliably achieve downsizing of the device. In addition, it is possible to more effectively suppress an increase in load applied to a driving means (for example, a motor, etc.) that moves the first component.

Means 9. The blister packaging machine according to any one of means 1 to 8, wherein the surface of the sheet punching support part is a horizontal flat surface.

When the surface of the sheet punching support portion is a horizontal flat surface as described in the above means 9, the bubble membrane conveyed along the horizontal flat surface may easily loosen toward the sheet punching support portion side due to its own weight. Therefore, there is a risk that the tympanic membrane may get caught on the downstream edge more easily.

In this regard, by employing the above-described means 1 and the like, it is possible to more reliably prevent the blister membrane from getting stuck even in a configuration in which the bleb membrane is prone to get stuck as described in the above-described means 9. In other words, it can be said that the above-mentioned means 1 and the like are particularly effective in the configuration of the above-mentioned means 9.

[Form used to implement the invention]

Hereinafter, an embodiment will be described with reference to the drawings. First, the structure of the PTP sheet in the form of a "bubble sheet" will be explained.

As shown in FIGS. 1 and 2 , the PTP sheet 1 has a container film 3 having a plurality of pockets 2 and a covering film 4 attached to the container film 3 so as to block the pockets 2 .

The container film 3 of this embodiment is made of a transparent thermoplastic resin material such as PP (polypropylene) and PVC (polyvinyl chloride), and has light transmittance. On the other hand, the coating 4 is made of an opaque material (for example, aluminum foil, etc.) with a sealant made of polypropylene resin or the like provided on the surface. Of course, the materials of each membrane 3 and 4 are not limited to the above, and other materials can also be used.

The PTP sheet 1 is produced by punching a strip-shaped PTP film 6 (see FIG. 3 ) formed of a strip-shaped container film 3 and a strip-shaped cover film 4 into a sheet, and is formed into a substantially rectangular shape in plan view. . In this embodiment, the PTP membrane 6 constitutes the "bubble membrane". The PTP film 6 is configured such that the portions to be the PTP sheets 1 are continuously arranged in the longitudinal direction of the PTP film 6 without gaps.

In the PTP sheet 1 , two rows of pockets composed of two pocket portions 2 arranged along the longitudinal direction are formed in two rows along the short side direction of the PTP sheet 1 . That is, four pocket portions 2 are formed in total. Each bag portion 2 stores one tablet 5 as "content".

Next, the schematic structure of the PTP packaging machine 10 for manufacturing the PTP sheet 1 will be described. In this embodiment, the PTP packaging machine 10 constitutes a "bubble packaging machine".

As shown in FIG. 4 , on the most upstream side of the PTP packaging machine 10 , the roll of the strip-shaped container film 3 is wound into a roll. The pulled-out end side of the container film 3 wound into a roll is guided to a guide roll 13 . The container film 3 is hung on the intermittent feed roller 14 on the downstream side of the guide roller 13 . The intermittent feed roller 14 is connected to a motor that rotates intermittently, and intermittently transports the container film 3 .

Between the guide roller 13 and the intermittent feed roller 14, a heating device 15 and a bag forming device 16 are sequentially arranged along the conveyance path of the container film 3. In addition, when the container film 3 is heated by the heating device 15 and becomes a relatively soft state, a plurality of pockets 2 are formed at predetermined positions of the container film 3 by the pocket forming device 16 . The bag portion 2 is formed during an interval between the conveyance operations of the container film 3 by the intermittent feed roller 14 .

The container film 3 fed out from the intermittent feed roller 14 is hung on a tension roll 18, a guide roller 19 and a film support roller 20 in this order. The film support roller 20 is connected to a motor that rotates at a constant speed, so the container film 3 is continuously transported at a constant speed. The tension roller 18 is configured to stretch the container film 3 toward the side that is elastically stretched by elastic force, thereby preventing the container film 3 from loosening due to the difference in the conveying actions of the intermittent feed roller 14 and the film support roller 20 . , and the container membrane 3 is always kept in a tight state.

A filling device 21 and an inspection device 22 are sequentially arranged between the guide roller 19 and the film support roller 20 along the conveyance path of the container film 3 .

The filling device 21 fills each bag portion 2 with the tablet 5 by, for example, opening a shutter at predetermined intervals to allow the tablet 5 to fall freely.

The inspection device 22 performs inspections, for example, on whether the tablet 5 is reliably filled into each bag 2 , whether there is any abnormality in the tablet 5 , whether there is foreign matter mixed in the bag 2 , and the like. The inspection results of the inspection device 22 are sent to the control device 61 described later.

On the other hand, the roll of the coating film 4 formed in a strip shape is wound into a roll shape on the most upstream side. The pulled-out end of the coating film 4 wound into a roll shape is guided to the heating roller 25 by the guide roller 24 .

The heating roller 25 is configured to be press-contacted with the film support roller 20 and to feed the container film 3 and the coating film 4 between the two rollers 20 and 25 . In addition, the container film 3 and the coating film 4 pass between the two rollers 20 and 25 in a heated and pressure-bonded state, whereby the coating film 4 is attached to the container film 3 and the bag portion 2 is blocked with the coating film 4 . Thereby, the belt-shaped PTP film 6 in which the tablet 5 is accommodated in each bag part 2 is manufactured.

The PTP film 6 sent out from the film support roller 20 is hung on the tension roller 27 and the intermittent feed roller 28 in order. The intermittent feed roller 28 is connected to a motor that rotates intermittently, so the PTP film 6 is intermittently transported. The tension roller 27 is configured to stretch the PTP film 6 toward the side that is elastically stretched by elastic force, thereby preventing the PTP film 6 from loosening due to the difference in the conveying actions of the film support roller 20 and the intermittent feed roller 28 . , and the PTP membrane 6 is always kept in a tight state.

The PTP film 6 fed out from the intermittent feed roller 28 is hung on the tension roller 31 and the intermittent feed roller 32 in order. The intermittent feed roller 32 is connected to a motor that rotates intermittently, so the PTP film 6 is intermittently transported. The tension roller 31 is configured to stretch the PTP film 6 toward the side that is elastically stretched by elastic force, thereby preventing the PTP film 6 from loosening between the intermittent feed rollers 28 and 32 . In this embodiment, the intermittent feed roller 32 constitutes the "conveying means".

A slit forming device 33 and a marking device 34 are sequentially arranged between the intermittent feed roller 28 and the tension roller 31 along the conveyance path of the PTP film 6 . The slit forming device 33 has a function of forming a cutting slit at a predetermined position of the PTP film 6 . The marking device 34 has a function of marking a predetermined position (for example, a tag portion) of the PTP film 6 . In addition, illustrations of the cutting slits and the markings are omitted in FIG. 1 and the like.

The PTP film 6 fed out from the intermittent feed roller 32 is sent to the sheet cutting device 37 . In this embodiment, the sheet cutting device 37 constitutes a "sheet cutting means". The sheet cutting device 37 is configured to punch out the outer edge of the single PTP sheet 1 from the PTP film 6 during the period between the conveying operations of the PTP film 6 by the intermittent conveying roller 32, that is, when the PTP film 6 is temporarily stopped. function and the function of cutting the scrap portion 7 described below.

The PTP sheet 1 punched out of the PTP film 6 by the sheet cutting device 37 is conveyed by a conveyor 39 and stored in a finished product hopper 40 . On the other hand, the waste portion 7 cut by the sheet cutting device 37 is stored in the waste hopper 43 and then separately disposed of. In addition, when the inspection device 22 makes a defective determination, the portion of the PTP film 6 that is relevant to the defective determination and corresponds to the PTP sheet 1 is not punched but is cut by the sheet cutting device 37 as the waste portion 7 .

Next, the sheet cutting device 37 will be described in more detail. The sheet cutting device 37 is provided with a first component part 51 and a second component part 52 provided at a position sandwiching the PTP film 6 (conveyance path of the PTP film 6) up and down.

The first component part 51 is disposed above the PTP film 6 and includes a base 511, a sheet punching blade 512, a scrap cutting blade 513 and a pressing part 514 as shown in FIGS. 5 to 7 . On the other hand, the second component part 52 is provided below the PTP film 6 and includes a sheet punching support part 521, a scrap cutting support part 522, and a film guide part 523. In this embodiment, the film guide part 523 constitutes "guiding means".

First, the first component 51 will be described. The base 511 is a base on which a sheet punching blade 512, a scrap cutting blade 513, and the like are provided. The base 511 is configured to be reciprocally movable in the up and down direction by a predetermined driving means (eg, motor, etc.) not shown in the figure.

In addition, the base 511 is provided with a hole portion 511a that opens toward the PTP film 6 side and in which the pressing portion 514 is inserted (see FIG. 7 ). The hole portion 511a is provided at a position facing a surface of the surface 5212 (the surface facing the PTP film 6 side) of the sheet punching support portion 521 that is located further downstream in the conveyance direction of the PTP film 6 than the punching hole 5211 described later. There are two locations. The two cavity portions 511a are respectively present at positions facing the width direction edge side portions of the PTP film 6 (that is, the portions of the PTP film 6 that remain after punching).

In addition, when the first component part 51 reciprocates up and down along with the movement of the base 511, the first component part 51 can move from a predetermined retreat position to two predetermined cutting positions. In addition, it can also move from the aforementioned retreat position. Move to a predetermined cutting position.

Here, the “retracted position” refers to a position in which the sheet punching blade 512 , the scrap cutting blade 513 and the pressing part 514 are separated from the PTP film 6 . On the other hand, the so-called "two cutting positions" means that the sheet punching blade 512 is inserted into the punching hole 5211 described later and the front end (lower end) of the scrap cutting blade 513 exceeds the PTP film 6 ( transport path) location. In addition, the so-called "one cutting position" refers to a position where the sheet punching blade 512 is not inserted into the punching hole 5211 and the tip of the scrap cutting blade 513 exceeds (the conveyance path of) the PTP film 6 .

The sheet punching knife 512 is used to cooperate with the sheet punching support part 521 to punch the PTP film 6 . A sharp blade 512a having a shape corresponding to the outer edge shape of the PTP sheet 1 is provided at the front end of the sheet punching blade 512 (the end on the PTP film 6 side) (see FIG. 6 ).

The waste material cutting knife 513 cooperates with the waste material cutting support part 522 to cut the waste material part 7 . The scrap cutting blade 513 is provided on the downstream side of the sheet punching blade 512 in the conveyance direction of the PTP film 6 .

In addition, the scrap portion 7 refers to a portion of the PTP film 6 located downstream of the sheet punching blade 512 in the conveyance direction of the PTP film 6 . Therefore, the so-called waste portion 7 basically refers to the portion of the PTP film 6 that remains after being punched by the sheet punching knife 512 etc., but the PTP film 6 is not punched and is directly transported to a location closer to the sheet punching knife 512. The portion on the downstream side in the conveyance direction is also included in the scrap portion 7 .

In addition, the scrap cutting blade 513 is configured not to protrude further toward the scrap cutting support portion 522 than the sheet punching blade 512 in the moving direction of the first component 51 (see FIG. 10 ). In this embodiment, the front end (lower end) of the scrap cutting blade 513 and the front end (lower end) of the sheet punching blade 512 are arranged at the same height along the movement direction of the first component part 51 . In addition, the scrap cutting blade 513 may be configured to retreat further away from the scrap cutting support part 522 than the sheet punching blade 512 in the moving direction of the first component part 51 . In addition, the scrap cutting blade 513 may be configured to protrude somewhat toward the scrap cutting support part 522 side than the sheet punching blade 512 in the moving direction of the first component part 51 .

The pressing part 514 is used to sandwich the PTP film 6 with the surface 5212 of the sheet punching support part 521 when the PTP film 6 is cut. In this embodiment, two pressing parts 514 are provided, and each pressing part 514 is respectively provided in the aforementioned hole part 511a. Each pressing part 514 is equipped with a spring 514a and a pressing pin 514b (see FIG. 7). In this embodiment, the spring 514a constitutes a "buffering means".

The spring 514a is constituted by a coil spring that is elastically deformable in the moving direction of the first component part 51, and is inserted into the hole part 511a. The spring 514a is fixed between the base 511 and the pressing ejector pin 514b. Thereby, the pressing part 514 can elastically deform in the moving direction of the first component part 51 .

The pressing ejector pin 514b is a rod-shaped part whose front end surface (lower end surface) is flat and whose base end (upper end) is inserted into the hole 511a. The pressing ejector pin 514b is configured to be guided in movement by the base 511 (especially the portion where the hole portion 511a is formed) when the spring 514a is elastically deformed. In addition, by configuring the hole portion 511a as described above, the pressing ejector pin 514b is provided at a position corresponding to the conveyance path of the width direction end edge side portion of the PTP film 6, and the front end surface of the pressing ejector pin 514b is formed to be The surface 5212 of the sheet punching support portion 521 is in a state in which the surfaces located on the downstream side in the conveyance direction from the punching holes 5211 described later are facing each other.

In addition, the front end surface of the pressing ejector pin 514b protrudes toward the sheet punching support portion 521 rather than the sheet punching blade 512 in the moving direction of the first component portion 51 . Thereby, when the first component part 51 moves toward the second component part 52 side, the front end surface of the pressing ejector pin 514b contacts the PTP film 6 before the sheet punching blade 512 contacts the PTP film 6 .

In addition, when the first component 51 is arranged in the retracted position, the distance from the front end surface of the pressing ejector pin 514b to the conveyance path of the PTP film 6 in the moving direction of the first component 51 is configured such that It is sufficiently larger than the distance from the waste material cutting blade 513 to the waste material cutting support part 522 (especially the waste material support blade 522a mentioned later) in the same moving direction. Thereby, when the first component part 51 moves to the second component part 52 side, the waste material part 7 can be removed by the waste material cutting blade 513 and the waste material supporting blade 522a before the front end surface of the pressing ejector pin 514b comes into contact with the PTP film 6 of cutting off.

Next, the second component part 52 will be described. The sheet punching support part 521 is disposed at a position facing the sheet punching blade 512 across the PTP film 6 and has a punching hole 5211 having a shape corresponding to the outer edge shape of the PTP sheet 1 . The punched hole 5211 is opened on the surface 5212 of the sheet punched support portion 521 (the surface located on the PTP film 6 side). In this embodiment, the surface 5212 of the sheet punch support portion 521 is a horizontal flat surface, and the PTP film 6 is conveyed along the surface 5212 in a substantially horizontal direction by the intermittent feed roller 32 .

In addition, the sheet punching support portion 521 has an edge portion 5213 corresponding to the punching hole 5211 on the surface 5212 side. The edge portion 5213 has a rectangular shape corresponding to the outer edge shape of the PTP sheet 1 . In this embodiment, the edge portion 5213 has a downstream edge portion 5213 a located on the downstream side in the aforementioned conveyance direction and extending in a direction intersecting the conveyance direction of the PTP film 6 when the PTP film 6 is viewed from above.

The scrap cutting support part 522 is provided on the downstream side of the sheet punching support part 521 in the conveying direction, and has a scrap supporting blade 522a that cooperates with the scrap cutting blade 513 to cut the scrap part 7 . In this embodiment, the scrap support blade 522a is formed by connecting the end surface of the scrap cutting support portion 522 on the most downstream side in the conveyance direction (a surface parallel to the moving direction of the first component portion 51) and the scrap cutting support portion 522. It is formed on the surface (the surface located on the PTP film 6 side) and has a square shape. In addition, the scrap supporting blade 522a may have a shape that becomes tapered toward the PTP film 6 side.

Furthermore, the scrap cutting support portion 522 is configured such that at least the scrap supporting blade 522a protrudes toward the scrap cutting blade 513 side in the moving direction of the first component 51 rather than the surface 5212 of the sheet punching support portion 521 . In this embodiment, the height H (see FIG. 8 ) of the scrap cutting support portion 522 relative to the surface 5212 of the sheet punching support portion 521 along the moving direction of the first component 51 is set to 3 mm or more and 8 mm or less. In addition, in FIG. 8 , part of the hatching is omitted for convenience of illustration.

The film guide 523 is provided between the sheet punching support part 521 and the waste cutting support part 522 , and guides the waste part 7 through a path close to the waste cutting blade 513 . In this embodiment, the film guide part 523 is composed of an inclined surface 523a connected to the aforementioned surface 5212 of the sheet punching support part 521 and sliding through the waste part 7 to guide the waste part 7 .

In addition, as shown in FIG. 8 , the smaller angle θ1 among the angles formed by the inclined surface 523 a with respect to the imaginary surface VS including the surface 5212 is set to be 10° or more and 20° or less (more The best is above 10° and below 15°).

In addition, in a cross section that is orthogonal to the aforementioned virtual plane VS and parallel to the conveyance direction of the PTP film 6 and passes through the downstream edge portion 5213a, from the most downstream portion Mp of the inclined surface 523a along the conveyance direction of the PTP film 6 toward the downstream edge Part 5213a draws an imaginary line VL. At this time, it is set so that the smaller angle θ2 among the angles formed by the imaginary line VL with respect to the imaginary surface VS is 5° or more and 20° or less (more preferably 5° or more and 15° or less). In addition, for the convenience of illustration, the angles θ1 and θ2 are shown in the drawings as angles larger than the above-mentioned respective ranges.

In addition, in the present embodiment, the PTP packaging machine 10 is equipped with a control device 61 capable of controlling the operations of various devices (for example, the intermittent feed roller 32 and the sheet cutting device 37, etc.) constituting the PTP packaging machine 10 (see Figure 4). The control device 61 is composed of a computer system including a CPU (Central Processing Unit) for calculation, ROM (Read Only Memory), RAM (Random Access Memory), etc. for data storage.

The control device 61 controls the operation of the sheet cutting device 37 so that the first component 51 is placed in the retracted position when the PTP film 6 is conveyed by the intermittent feed roller 32 . On the other hand, the control device 61 temporarily punches the portion of the PTP film 6 that is to be punched by the sheet cutting device 37 (the sheet punching blade 512 and the like) (the portion that becomes the PTP sheet 1 ). When the knife 512 and the sheet punching support part 521 are stopped (see FIGS. 9 and 10 ), the operation of the first component part 51 is controlled so as to perform an operation corresponding to the inspection result sent from the inspection device 22 .

More specifically, when the inspection device 22 determines that the portion of the PTP film 6 to be punched by the sheet cutting device 37 is defective, the control device 61 moves from the retreat position to the one cutting position. The operation of the first component 51 is controlled in a manner (see FIG. 11 ). Thereby, the waste part 7 is cut by the waste cutting blade 513 and the waste cutting support part 522 (the waste support blade 522a) without punching the PTP film 6. Then, the control device 61 controls the operation of the first component 51 so as to move back to the retreat position.

On the other hand, when the inspection device 22 determines that the portion of the PTP film 6 to be punched by the sheet cutting device 37 is good, the control device 61 moves from the retreat position to the two cutting positions. The mode controls the operation of the first component 51. At this time, the first component part 51 first reaches the aforementioned cutting position, whereby the waste part 7 is cut by the waste cutting blade 513 and the waste cutting support part 522 before the pressing part 514 contacts the PTP film 6 ( Refer to Figure 11).

Then, the first component part 51 further moves toward the second component part 52 side, whereby before the sheet punching blade 512 contacts the PTP film 6, the pressing part 514 (pressing ejector pin 514b) and the sheet punching support part 521 The surface 5212 of the PTP film 6 is sandwiched (refer to Figure 12). Thereby, the PTP film 6 that was originally lifted from the surface 5212 by the film guide 523 comes into contact with the surface 5212 around the punched hole 5211 .

Then, the first component part 51 further moves toward the second component part 52 side and reaches the aforementioned two cutting positions. Thereby, the sheet punching blade 512 (blade portion 512a) is inserted into the punching hole 5211, and the sheet punching hole 5211 is cut. The punching blade 512 and the sheet punching support part 521 punch out the PTP film 6 (see FIGS. 13 and 14 ). In addition, after the PTP film 6 is clamped by the pressing portion 514 and the like, the elastic deformation of the spring 514 a does not hinder the movement of the first component 51 toward the two cutting positions.

Then, the control device 61 controls the operation of the first component 51 so as to move back to the retreat position. As the first component part 51 moves to the retracted position, the pressing part 514 separates from the PTP film 6, and the PTP film 6 returns to a floating state from at least the downstream edge part 5213a (see FIG. 15). Then, the control device 61 controls the operation of the intermittent feed roller 32 so that the PTP film 6 is conveyed by a certain amount. At this time, the PTP film 6 is conveyed in a state of floating at least from the downstream edge portion 5213a.

Thereafter, the first component 51 is controlled to perform an operation corresponding to the inspection result of the inspection device 22 every time the PTP film 6 is temporarily stopped. As a result, the PTP film 6 is selectively cut without punching and only the waste material is cut. Part 7 or die-cut the PTP film 6 and cut off the waste part 7. In addition, each time the waste portion 7 is cut and the PTP film 6 is punched, the PTP film 6 is transported by a certain amount in a state of floating from the downstream edge portion 5213a.

As described in detail above, according to this embodiment, at least when the first component part 51 is arranged in the retracted position, the PTP film 6 is floated (separated) from the downstream edge part 5213a by the film guide part 523 . Therefore, the PTP film 6 can be conveyed in a state where the PTP film 6 floats from the downstream edge portion 5213a. Therefore, it is possible to effectively suppress the PTP film 6 from being caught on the downstream edge portion 5213 a where the PTP film 6 is particularly likely to be caught, and to more reliably prevent the PTP film 6 from being caught on the sheet punch support portion 521 . Thereby, the PTP film 6 can be conveyed more smoothly, and the operation stability of the PTP packaging machine 10 can be improved.

In addition, especially in this embodiment, among the corner corresponding portions 9 (see FIG. 15 ) that remain after punching and correspond to the outer edge corners of the PTP sheet 1, particularly the portions facing forward in the forward direction are caught in the However, according to this embodiment, the corner corresponding portion 9 can be more reliably prevented from being caught on the downstream edge portion 5213a.

In addition, the portion (scrap support blade 522a) of the scrap cutting support portion 522 that cooperates with the scrap cutting blade 513 to cut the scrap portion 7 is further toward the scrap cutting than the surface 5212 of the sheet punching support portion 521. The 513 side of the broken knife protrudes. Therefore, even if the first component part 51 is configured so that the scrap cutting blade 513 does not protrude from the sheet punching blade 512 in the moving direction of the first component part 51 , the first component part 51 is arranged at one cutting position (only position when cutting the scrap portion 7 ), it is still possible to more reliably prevent the sheet punching blade 512 from contacting the PTP film 6 . This makes it possible to reduce the size of the first component part 51 and to stably cut only the scrap part 7 by moving the first component part 51 to one cutting position. In addition, the degree of design freedom regarding the positional relationship between the scrap cutting blade 513 and the sheet punching blade 512 can be further improved.

In addition, when the first component 51 is moved from the retreat position to the two cutting positions in order to punch out the PTP film 6, before the sheet punching blade 512 contacts the PTP film 6 (before reaching the two cutting positions), The surface 5212 of the sheet punch support part 521 and the pressing part 514 sandwich the PTP film 6 . Thereby, the PTP film 6 originally lifted from the surface 5212 by the film guide 523 comes into contact with the surface 5212 . In addition, in this state, the first component 51 moves to two cutting positions, thereby punching out the PTP film 6 . Therefore, compared with directly punching the PTP film 6 while the PTP film 6 is floating from the surface 5212, it is possible to more reliably prevent the punching position from being displaced. As a result, the product quality of the produced PTP sheet 1 can be improved.

At the same time, according to this embodiment, the PTP film 6 can be clamped by the pressing part 514 and the like before the sheet punching blade 512 contacts the PTP film 6, and the spring 514a of the pressing part 514 can also clamp the PTP film 6 before the sheet punching blade 512 contacts the PTP film 6. After that, the first component 51 is allowed to move further.

In addition, before the pressing part 514 contacts the PTP film 6, the waste cutting blade 513 and the waste cutting support part 522 are used to cut the waste part 7. Therefore, when the waste part 7 is cut, there is no impact on the first part from the pressing part 514. The component part 51 exerts a force in a direction that interferes with its movement. Therefore, it is possible to suppress an increase in the load (moment, etc.) applied to the driving means for moving the first component 51 .

In addition, the scrap cutting blade 513 is configured not to protrude further toward the scrap cutting support portion 522 than the sheet punching blade 512 in the moving direction of the first component 51, so it is possible to further reduce the size of the first component 51 along its direction. The size in the direction of movement. Thereby, the sheet cutting device 37 can be more reliably reduced in size. In addition, it is possible to more effectively suppress increases in various costs.

In addition, since the film guide part 523 is a simple inclined surface 523a, the structure of the film guide part 523 can be simplified. This makes it possible to more effectively suppress increases in various costs.

In addition, by setting the angle θ1 to 10° or more, the angle θ2 to 5° or more, or the height H to 3 mm or more, the PTP film 6 can be more reliably lifted from the downstream edge portion 5213a.

On the other hand, by configuring the angles θ1 and θ2 to be 20° or less respectively, or the height H being 8 mm or less, it is possible to more reliably prevent the scrap cutting support part 522 from cutting the surface 5212 (imaginary surface) of the sheet punching support part 521 The protrusion (height) of VS) is too large. Therefore, the stroke of the first component 51 when moving from the retreat position to the two cutting positions can be more reliably prevented than the stroke amount of the first component 51 when moving from the retreat position to one cutting position. A situation in which the quantity increases extremely. This makes it possible to more effectively reduce the size of the sheet cutting device 37 . In addition, it is possible to more effectively suppress an increase in the load applied to the driving means for moving the first component part 51 .

In addition, the technical matter for floating the PTP film 6 from the downstream edge portion 5213a is as described in this embodiment. The surface 5212 of the sheet punching support portion 521 is a horizontal flat surface and the PTP is conveyed along the horizontal flat surface. It is particularly effective in the constitution of membrane 6 . In this structure, the PTP film 6 tends to loosen toward the sheet punch support portion 521 due to its own weight, so the PTP film 6 is more likely to get caught on the downstream edge portion 5213a.

In addition, the invention is not limited to the description of the above embodiment, and may be implemented as follows, for example. Needless to say, other application examples and modification examples not illustrated below can also be implemented.

(a) In the above embodiment, the pressing part 514 is configured to sandwich the PTP film 6 with the surface 5212 of the sheet punching support part 521 and is located downstream of the punching hole 5211 in the conveyance direction of the PTP film 6 between the side faces. On the other hand, the pressing part 514 may be configured so that the PTP film 6 is sandwiched between the surface 5212 of the sheet punching support part 521 and the surface exists at a position including the punching hole 5211 in the width direction of the PTP film 6 and It is located between the surfaces on the downstream side in the conveying direction from the center of the punched hole 5211.

In addition, the pressing part 514 does not necessarily have to include the spring 514a and the pressing ejector pin 514b. For example, the pressing part may have only the spring 514a, and the PTP film 6 may be clamped by the spring 514a. In addition, as the buffering means, parts that can be elastically deformed in the moving direction of the first component part 51 (for example, cushioning parts and air cushions made of foamed resin, etc.) may also be used. An air cylinder capable of telescopic deformation in the moving direction may also be used. In addition, the pressing ejector pin 514 b may be replaced by a plate-shaped or rod-shaped component extending in the width direction of the PTP film 6 .

(b) In the above embodiment, the film guide part 523 is composed of the inclined surface 523a, but the film guide part only needs to be able to guide the waste material part 7 through a path close to the waste material cutting blade 513, forming the PTP The state in which the membrane 6 floats from the downstream edge portion 5213a can be appropriately changed. Therefore, for example, the film guide portion may be configured by a step portion protruding toward the scrap cutting blade 513 side from the surface 5212 of the sheet punching support portion 521, a rotatable roller, or the like. In addition, the film guide part may have a stepped shape, for example.

(c) In the above embodiment, the PTP film 6 is configured to be conveyed in a substantially horizontal direction along the horizontal surface 5212 at the location where the sheet punching support portion 521 is arranged. However, the PTP film 6 may also be transported along the horizontal surface 5212 of the sheet punching support portion 521 . The conveyance direction of the PTP film 6 at the placement location is appropriately changed. For example, the surface of the sheet punch support part may be designed as a flat vertical surface, and the PTP film 6 may be conveyed in a substantially vertical direction along this surface.

(d) The structure of the PTP sheet 1 exemplified in the above embodiment is only an example. For example, the number and arrangement of the pockets 2 included in the PTP sheet 1 may be appropriately changed.

(e) In the above embodiment, the PTP film 6 is configured such that the number of pocket portions 2 corresponding to one piece is arranged along the width direction thereof, but the structure of the PTP film 6 is not limited to this. For example, the PTP film 6 may be configured such that the number of pockets 2 corresponding to two or more sheets is arranged along the width direction thereof.

In addition, in the above-mentioned embodiment, the PTP film 6 is configured so that the portions that become the PTP sheet 1 are continuously arranged without gaps along the longitudinal direction of the PTP film 6 . However, it may also be configured such that the portions that become the PTP sheet 1 are arranged along the longitudinal direction of the PTP film 6 . The PTP films 6 are arranged at certain intervals in the longitudinal direction.
