Blister packaging machine

Abstract

The present application aims to provide a blister packaging machine which can more reliably prevent the blister film from being caught in a device for punching the blister film. The PTP packaging machine has a film guide portion (523) between the sheet punching support portion (521) and the waste cutting support portion (522), which guides the waste portion (7) through a path close to the waste cutting knife (513) side, and enables the PTP film (6) to float up from the downstream edge portion (5213a) in the conveying direction downstream side of the PTP film (6) among the edge portions (5213) corresponding to the punching holes (5211) in the sheet punching support portion (521). Thus, the situation of the PTP film (6) being caught on the downstream edge portion (5213a) where the PTP film (6) is particularly prone to being caught is effectively suppressed, and the PTP film (6) can be more reliably prevented from being caught in the sheet punching support portion (521), a device for punching the PTP film (6).

Description

Technical Field

[0001] This invention relates to a blister packaging machine for manufacturing blister sheets containing tablets or the like. Background Technology

[0002] For blister packs commonly used in pharmaceuticals and food, PTP (Press Through Package) packs are known. A PTP pack comprises: a container film having a pouch portion for containing the contents such as tablets; and a cover film that seals the container film to the open side of the pouch portion.

[0003] PTP sheets are manufactured using a type of blister packaging machine, namely a PTP packaging machine. The PTP packaging machine includes a bag forming mechanism, a filling mechanism, a sealing mechanism, and a punching mechanism. The bag forming mechanism forms a bag portion from a strip of container film. The filling mechanism fills the bag portion with the contents. The sealing mechanism applies a film to the container film to seal the opening of the bag portion. The punching mechanism punches the strip of PTP film formed by applying the film to the container film. PTP sheets are obtained by punching the PTP film.

[0004] Furthermore, the portion of the PTP film located downstream of the punching mechanism, namely the scrap portion (e.g., the unwanted portion after punching), is cut off by a predetermined scrap cutting mechanism. In recent years, devices integrating the punching mechanism and the scrap cutting mechanism have been proposed (see, for example, Patent Document 1 below).

[0005] The apparatus in Patent Document 1 includes: a sheet punching cutter; a cutter head having a waste cutting cutter disposed downstream of the sheet punching cutter in the conveying direction of the PTP film and protruding sufficiently towards the PTP film side than the sheet punching cutter; and a substrate having a punching hole (opening) through which the sheet punching cutter can be inserted and disposed in a position to clamp the PTP film between the substrate and the aforementioned cutter head. In this apparatus, by adjusting the amount of movement of the cutter head toward the substrate side, it is possible to selectively punch the PTP film and cut off the waste portion, or to cut off only the waste portion without punching the PTP film.

[0006] More specifically, the blade head is moved such that the sheet-cutting cutter is inserted into the aforementioned cutting hole, thereby cutting the PTP film with the sheet-cutting cutter and cutting off the waste portion with the waste cutting cutter. On the other hand, by moving the blade head to a position where the waste cutting cutter penetrates the PTP film without inserting the cutting cutter into the aforementioned cutting hole, only the waste portion is cut off without cutting the PTP film.

[0009] Patent Document 1: International Patent Publication No. 2021 / 225112 Summary of the Invention

[0010] [The problem the invention aims to solve]

[0011] Furthermore, in the aforementioned device, such as Figure 16 (For ease of illustration, Figure 16 As shown in the diagram (where the PTP film 6 is displayed as thicker than it actually is), the PTP film 6 is conveyed along the surface of the substrate 101. Therefore, as... Figure 17 As shown, there is a risk that a portion of the PTP film 6 (waste section 7) in which the hole 8 (the hole corresponding to the PTP sheet 1) is formed, particularly the portion facing forward in the forward direction, may become stuck in the downstream edge 103 of the substrate 101 corresponding to the punching hole 102, particularly in the downstream direction of the PTP film 6. If this sticking occurs, the manufacturing of the PTP sheet 1 may malfunction.

[0012] The present invention was made in view of the above circumstances, and its object is to provide a blister packaging machine that can more reliably prevent blister film from getting caught on the device for cutting blister film.

[0013] [Technical solution used to solve the problem]

[0014] The following sections provide a detailed explanation of each technical solution addressing the aforementioned issues. Additionally, if necessary, the specific effects of each technical solution will be noted.

[0015] Technical Solution 1. A blister packaging machine, which manufactures blister sheets by punching and cutting strip-shaped blister film in units of sheets, wherein the aforementioned strip-shaped blister film is formed by attaching a strip-shaped container film containing contents in a bag portion to the bag portion by sealing the bag portion, characterized in that it comprises:

[0016] The conveying mechanism intermittently conveys the aforementioned blister film; and

[0017] A sheet-cutting mechanism that cuts the aforementioned blister film that has been temporarily stopped;

[0018] The aforementioned sheet cutting mechanism includes a first component and a second component located at the position where the aforementioned blister film is clamped;

[0019] The aforementioned first constituent part has:

[0020] A sheet cutting blade having a blade portion with a shape corresponding to the outer edge shape of the aforementioned blister sheet; and

[0021] The waste cutting blade is located downstream of the aforementioned blister film conveying direction, which is further downstream than the aforementioned sheet cutting blade.

[0022] The aforementioned second component has:

[0023] A sheet-cutting support portion, configured to convey the aforementioned blister film along a flat surface, and having a punching hole with a shape corresponding to the outer edge shape of the aforementioned blister sheet and opening onto the aforementioned surface; and

[0024] The waste cutting support is located further downstream of the aforementioned conveying direction than the aforementioned sheet punching support;

[0025] The blister packaging machine is configured such that the aforementioned first component moves from a retracted position where the aforementioned sheet cutting blade and the aforementioned waste cutting blade are separated from the aforementioned blister film to two predetermined cutting positions, whereby the aforementioned sheet cutting blade is inserted through the aforementioned cutting hole and the aforementioned sheet cutting blade and the aforementioned sheet cutting support cut the aforementioned blister film, and the aforementioned waste cutting blade and the aforementioned waste cutting support cut the waste portion of the aforementioned blister film located downstream of the aforementioned conveying direction than the aforementioned sheet cutting blade;

[0026] On the other hand, the first component is configured such that it moves from the retraction position to a predetermined side cutting position, thereby cutting the waste portion by the waste cutting blade and the waste cutting support without cutting the blister film.

[0027] A guide mechanism is provided between the aforementioned sheet punching support and the aforementioned waste cutting support in the aforementioned second component. The waste part is guided through a path that approaches the aforementioned waste cutting blade. At least when the aforementioned first component is arranged in the aforementioned retraction position, a state is formed in which the aforementioned blister film floats up from the downstream edge of the edge portion corresponding to the aforementioned punching hole in the aforementioned sheet punching support, which is located downstream of the aforementioned conveying direction.

[0028] At least the portion of the aforementioned waste cutting support that works in conjunction with the aforementioned waste cutting blade to cut the aforementioned waste portion protrudes further toward the aforementioned waste cutting blade side than the aforementioned surface of the aforementioned sheet cutting support in the moving direction of the aforementioned first component.

[0029] According to the above-described technical solution 1, the guide mechanism guides the waste section through a path approaching the waste cutting blade, at least in the first component, to a retracted position, forming a state where the blister film floats (departs) from the downstream edge of the sheet-cutting support. Therefore, the blister film can be transported in a state where it floats from the downstream edge. This effectively suppresses the blister film from getting stuck on the downstream edge, which is particularly problematic, and more reliably prevents the blister film from getting stuck on the sheet-cutting support (the device for cutting the blister film). Consequently, the blister film can be transported more smoothly, improving the operational stability of the device.

[0030] Furthermore, the portion of the waste cutting support that works in conjunction with the waste cutting blade to cut the waste portion protrudes further towards the waste cutting blade than the surface of the sheet-cutting support. Therefore, even if the first component is formed such that the waste cutting blade does not protrude much or not at all from the sheet-cutting blade along the moving direction of the first component, when the first component is positioned in a one-sided cutting position (the position when only the waste portion is cut), it is still possible to more reliably prevent the sheet-cutting blade from contacting the blister film. Thus, both miniaturization of the first component and stable cutting of only the waste portion by moving the first component to a one-sided cutting position are achieved. Furthermore, the design freedom related to the positions of the waste cutting blade and the sheet-cutting blade can be further increased.

[0031] Technical Solution 2. The blister packaging machine according to Technical Solution 1, wherein the aforementioned first component has a pressing part that can clamp the aforementioned blister film between the aforementioned surface of the aforementioned sheet punching support part, and has a predetermined buffer mechanism.

[0032] The blister packaging machine is configured such that, when the aforementioned first component moves from the aforementioned retracted position to the aforementioned two cutting positions, the aforementioned blister film is clamped by the aforementioned pressing part and the aforementioned surfaces of the aforementioned sheet cutting support part before the aforementioned sheet cutting blade contacts the aforementioned blister film, and after the blister film is clamped, the aforementioned buffer mechanism is used to avoid obstructing the movement of the first component to the aforementioned two cutting positions.

[0033] According to the above-described technical solution 2, when the first component moves from the retracted position to the two cutting positions for punching the blister film, the blister film is clamped between the surface of the sheet-cutting support and the pressing part before the sheet-cutting blade contacts the blister film (before reaching the two cutting positions). Thus, the blister film, which was originally floating off the surface of the sheet-cutting support by the guide mechanism, is now in contact with the surface of the sheet-cutting support. Furthermore, in this state, the first component moves to the two cutting positions, thereby punching the blister film. Therefore, compared to directly punching the blister film while it is floating off the surface of the sheet-cutting support, it is more reliable to prevent the punching position from shifting. As a result, the quality of the manufactured blister sheets can be improved.

[0034] Furthermore, the blister film can be clamped by the pressing part before the blister cutter contacts it, and the cushioning mechanism of the pressing part also allows for further movement of the first component after clamping.

[0035] Technical Solution 3. A blister packaging machine according to Technical Solution 2, wherein the blister packaging machine is configured such that, when the aforementioned first component moves from the aforementioned retracted position to the aforementioned two cutting positions, the aforementioned waste material is cut off by the aforementioned waste material cutting blade and the aforementioned waste material cutting support before the aforementioned pressing part contacts the aforementioned blister film.

[0036] According to the above-described technical solution 3, when the waste section is cut, no force is applied to the first component from the pressing section in a direction that would hinder its movement. Therefore, it is possible to suppress the increase of the load (torque, etc.) on the drive mechanism (e.g., a motor) used to move the first component.

[0037] Alternatively, it can be configured such that "when the aforementioned first component moves from the aforementioned retracted position to the aforementioned two cutting positions, before the aforementioned pressing portion clamps the aforementioned blister film between the aforementioned surface of the aforementioned sheet cutting support portion, the aforementioned waste cutting blade and the aforementioned waste cutting support portion cut off the aforementioned waste portion." In this configuration, it is also possible to suppress the increase in load applied to the drive mechanism that moves the first component.

[0038] Technical Solution 4. A blister packaging machine according to any one of Technical Solutions 1 to 3, wherein the aforementioned waste cutting blade is configured such that, along the moving direction of the aforementioned first component, it does not protrude further toward the aforementioned waste cutting support than the aforementioned sheet cutting blade.

[0039] According to the above-described technical solution 4, the dimension of the first component along its moving direction can be further reduced. This allows for more reliable miniaturization of the device. Furthermore, it enables more effective suppression of various cost increases.

[0040] Technical solution 5. A blister packaging machine according to any one of technical solutions 1 to 4, wherein the aforementioned guiding mechanism is an inclined surface that guides the waste section by sliding through the aforementioned waste section.

[0041] According to the above technical solution 5, the guide mechanism is a simple inclined surface, which simplifies the construction of the guide mechanism. Therefore, it is possible to more effectively suppress the increase in various costs.

[0042] Technical Solution 6. The blister packaging machine according to Technical Solution 5, wherein the angle θ1 of the angle formed between the aforementioned inclined surface and the imaginary surface containing the aforementioned sheet punching support portion is 10° or more and 20° or less.

[0043] According to the above technical solution 6, the angle θ1 is configured to be 10° or more, so that the blister film can be floated more reliably from the downstream edge.

[0044] On the other hand, since the angle θ1 is configured to be 20° or less, it is possible to more reliably prevent the protrusion (height) of the waste cutting support relative to the surface (imaginary surface) of the sheet punching support from being too large. Therefore, it is possible to more reliably prevent the stroke of the first component when moving from the retracted position to both cutting positions from an extreme increase compared to the stroke of the first component when moving from the retracted position to one cutting position. As a result, it is possible to more effectively achieve miniaturization of the device and to more effectively suppress the increase in load applied to the drive mechanism (e.g., a motor) used to move the first component.

[0045] Technical Solution 7. A blister packaging machine according to Technical Solution 5 or 6, wherein, in a cross section orthogonal to the aforementioned surface containing the aforementioned sheet cutting support portion and parallel to the aforementioned blister film conveying direction and passing through the aforementioned downstream edge portion, the angle θ2 of the imaginary line drawn from the most downstream portion of the aforementioned inclined surface along the aforementioned blister film conveying direction to the aforementioned downstream edge portion relative to the aforementioned imaginary surface is 5° or more and 20° or less.

[0046] According to the above technical solution 7, the angle θ2 is configured to be 5° or more, so that the blister film can float more reliably from the downstream edge.

[0047] On the other hand, since the angle θ2 is configured to be 20° or less, it is possible to more reliably prevent excessive protrusion (height) of the waste cutting support relative to the surface (imaginary surface) of the sheet punching support. As a result, the stroke of the first component when moving from the retracted position to the two cutting positions can be reduced. Therefore, it is possible to achieve more reliable miniaturization of the device and to more effectively suppress the increase in load applied to the drive mechanism (e.g., a motor) that moves the first component.

[0048] Technical Solution 8. A blister packaging machine according to any one of Technical Solutions 5 to 7, wherein the height H of the aforementioned waste cutting support relative to the aforementioned surface of the aforementioned sheet punching support along the moving direction of the aforementioned first component is 3 mm or more and 8 mm or less.

[0049] According to the above technical solution 8, the height H is 3mm or more, so the blister film can be reliably floated from the downstream edge.

[0050] On the other hand, with a height H of 8mm or less, the stroke of the first component when moving from the retracted position to the two cut-off positions is smaller. This allows for more reliable miniaturization of the device. Furthermore, it enables more effective suppression of the increase in load applied to the drive mechanism (e.g., a motor) that moves the first component.

[0051] Technical Solution 9. A blister packaging machine according to any one of Technical Solutions 1 to 8, wherein the aforementioned surface of the aforementioned sheet punching support is a horizontal flat surface.

[0052] When the surface of the sheet-cutting support portion is a horizontal, flat surface as described in technical solution 9 above, the blister film transported along this horizontal, flat surface is prone to loosening towards the sheet-cutting support portion due to its own weight. Therefore, there is a greater risk that the blister film may get caught on the downstream edge.

[0053] In this respect, by adopting the above-described technical solution 1, even in a configuration where blister film snagging is prone to occur as described in technical solution 9, blister film snagging can be prevented more reliably. In other words, the above-described technical solution 1 can be said to be particularly effective in the configuration of technical solution 9. Attached Figure Description

[0071] The following description focuses on one embodiment, with reference to the accompanying drawings. First, the structure of the PTP sheet in the form of a "bubble sheet" will be explained.

[0072] like Figure 1 , Figure 2 As shown, the PTP sheet 1 has: a container film 3 having a plurality of bag portions 2; and a covering film 4 installed on the container film 3 in such a way as to block the bag portions 2.

[0073] The container membrane 3 in this embodiment is formed, for example, from a transparent thermoplastic resin material such as PP (polypropylene) and PVC (polyvinyl chloride), and is translucent. On the other hand, the coating 4 is formed, for example, from an opaque material (such as aluminum foil) with a sealant made of polypropylene resin or the like on its surface. Of course, the materials of each membrane 3 and 4 are not limited to the above, and other materials may be used.

[0074] PTP sheet 1 is a strip-shaped PTP film 6 formed by a strip-shaped container film 3 and a strip-shaped coating film 4 (see reference). Figure 3 It is manufactured by punching into sheets, and when viewed from above, it is roughly rectangular in shape. In this embodiment, the PTP film 6 constitutes a "bubble film". The PTP film 6 is configured such that the portions that become the PTP sheet 1 are arranged continuously without gaps along the long side of the PTP film 6.

[0075] In the PTP tablet 1, two rows of pouches 2 arranged along its long side are formed along the short side of the PTP tablet 1. That is, a total of four pouches 2 are formed. In each pouch 2, one pouch contains one tablet 5 as the "contents".

[0076] Next, the general configuration of the PTP packaging machine 10 used to manufacture the aforementioned PTP sheet 1 will be described. In this embodiment, the PTP packaging machine 10 is a "blister packaging machine".

[0077] like Figure 4 As shown, on the upstream side of the PTP packaging machine 10, a roll of strip-shaped container film 3 is wound into a cylinder. The pull-out end of the wound container film 3 is guided to guide roller 13. The container film 3 is hung on intermittent feed roller 14 on the downstream side of guide roller 13. Intermittent feed roller 14 is connected to an intermittently rotating motor, which intermittently transports the container film 3.

[0078] A heating device 15 and a bag-forming device 16 are sequentially arranged between the guide roller 13 and the intermittent feed roller 14 along the transport path of the container film 3. Furthermore, when the container film 3 is heated by the heating device 15 and becomes more flexible, the bag-forming device 16 forms multiple bags 2 at predetermined positions on the container film 3. The formation of the bag 2 occurs during the transport operation of the container film 3 performed by the intermittent feed roller 14.

[0079] The container membrane 3, fed from the intermittent feed roller 14, is sequentially mounted on the tension roller 18, guide roller 19, and membrane support roller 20. The membrane support roller 20 is connected to a motor rotating at a constant speed, thus continuously and at a constant speed conveying the container membrane 3. The tension roller 18 is configured to stretch the container membrane 3 towards the taut side using elastic force, preventing slack in the container membrane 3 caused by the difference in conveying action between the intermittent feed roller 14 and the membrane support roller 20, and keeping the container membrane 3 in a taut state at all times.

[0080] A filling device 21 and an inspection device 22 are sequentially arranged between the guide roller 19 and the membrane support roller 20 along the conveying path of the container membrane 3.

[0081] The filling device 21 fills the tablets 5 into each bag section 2 by opening the shutter at predetermined intervals to allow the tablets 5 to fall freely.

[0082] The inspection device 22 performs checks, for example, on whether the tablets 5 are reliably filled into each bag portion 2, whether the tablets 5 are abnormal, and whether foreign matter has been mixed into the bag portion 2. The inspection results of the inspection device 22 are sent to the control device 61, which will be described later.

[0083] On the other hand, the roll of film 4, which is formed into a strip, is wound into a cylinder on the upstream side. The pull-out end of the film 4, which is wound into a cylinder, is guided to the heating roller 25 by the guide roller 24.

[0084] The heating roller 25 is configured to press against the aforementioned film support roller 20, thereby feeding the container film 3 and the coating film 4 between the two rollers 20 and 25. Furthermore, the container film 3 and the coating film 4 pass between the two rollers 20 and 25 in a heated and pressed state, thereby attaching the coating film 4 to the container film 3 and sealing the bag portion 2. This produces a strip-shaped PTP film 6 that houses the tablets 5 in each bag portion 2.

[0085] The PTP membrane 6 fed from the membrane support roller 20 is sequentially mounted on the tension roller 27 and the intermittent feed roller 28. The intermittent feed roller 28 is connected to an intermittently rotating motor, thus intermittently conveying the PTP membrane 6. The tension roller 27 is configured to stretch the PTP membrane 6 towards the taut side using elastic force, preventing the PTP membrane 6 from slackening due to the difference in conveying action between the membrane support roller 20 and the intermittent feed roller 28, and keeping the PTP membrane 6 in a taut state at all times.

[0086] The PTP film 6 fed from the intermittent feed roller 28 is sequentially mounted on the tension roller 31 and the intermittent feed roller 32. The intermittent feed roller 32 is connected to an intermittently rotating motor, thus intermittently conveying the PTP film 6. The tension roller 31 is configured to stretch the PTP film 6 to a taut side using elastic force, preventing the PTP film 6 between the intermittent feed rollers 28 and 32 from slackening. In this embodiment, the intermittent feed roller 32 constitutes a "conveying mechanism".

[0087] A slit forming device 33 and an marking device 34 are sequentially arranged along the conveying path of the PTP film 6 between the intermittent feed roller 28 and the tension roller 31. The slit forming device 33 has the function of forming a cutting slit at a predetermined position on the PTP film 6. The marking device 34 has the function of applying marking at a predetermined position (e.g., the label section) on the PTP film 6. Additionally, in Figure 1 The diagrams of the slits and engravings used for cutting are omitted from the text.

[0088] The PTP film 6 fed 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 mechanism". The sheet cutting device 37 has the function of punching the outer edge of a single PTP sheet 1 of the PTP film 6 during the conveying operation of the PTP film 6 by the intermittent conveying roller 32, that is, when the PTP film 6 is temporarily stopped, and the function of cutting off the waste portion 7 described later.

[0089] The PTP sheet 1 obtained by punching the PTP film 6 using the sheet cutting device 37 is conveyed by the conveyor 39 and stored in the finished product hopper 40. On the other hand, the waste portion 7 cut by the sheet cutting device 37 is disposed of separately after being stored in the waste hopper 43. In addition, when the inspection device 22 determines that the object is unqualified, the portion of the PTP film 6 corresponding to the unqualified PTP sheet 1 is not punched but is cut as waste portion 7 by the sheet cutting device 37.

[0090] Next, the sheet cutting device 37 will be described in more detail. The sheet cutting device 37 includes a first component 51 and a second component 52 provided at positions that clamp the PTP film 6 (the transport path of the PTP film 6) from above and below.

[0091] The first component 51 is disposed above the PTP membrane 6, such as Figures 5 to 7 As shown, the device includes a substrate 511, a sheet cutting blade 512, a waste cutting blade 513, and a pressing part 514. On the other hand, a second component 52 is provided below the PTP membrane 6 and includes a sheet cutting support 521, a waste cutting support 522, and a membrane guide 523. In this embodiment, the membrane guide 523 constitutes a "guide mechanism".

[0092] First, the first component 51 will be described. The base 511 is a platform on which a blanking cutter 512 and a waste cutting cutter 513 are mounted. The base 511 is configured to be able to reciprocate in the vertical direction by a predetermined drive mechanism (e.g., a motor) not shown.

[0093] In addition, the substrate 511 has a cavity 511a with an opening facing the PTP membrane 6 and into which the pressing part 514 is inserted (see reference). Figure 7 The cavity 511a has two locations on the surface 5212 (the surface facing the PTP film 6) of the sheet punching support 521, which are located downstream of the PTP film 6 in the conveying direction, more so than the punching hole 5211 described later. These two cavities 511a are respectively located opposite to the width-direction edge portion of the PTP film 6 (i.e., the portion remaining after punching in the PTP film 6).

[0094] Furthermore, when the first component 51 moves up and down as the base 511 moves, the first component 51 can move from a predetermined retraction position to two predetermined cutting positions, and can also move from the aforementioned retraction position to a predetermined one-sided cutting position.

[0095] Here, the term "retreat position" refers to a position where the sheet cutting blade 512, the waste cutting blade 513, and the pressing part 514 are disengaged from the PTP film 6. On the other hand, the term "two-point cutting position" refers to a position where the sheet cutting blade 512 is inserted through the cutting hole 5211 (described later) and the front end (lower end) of the waste cutting blade 513 extends beyond the PTP film 6 (the transport path). Furthermore, the term "one-sided cutting position" refers to a position where the sheet cutting blade 512 is not inserted through the cutting hole 5211 and the front end of the waste cutting blade 513 extends beyond the PTP film 6 (the transport path).

[0096] The sheet cutting blade 512 is used in conjunction with the sheet cutting support 521 to cut the PTP film 6. At the front end of the sheet cutting blade 512 (the end on the PTP film 6 side), there is a sharp blade portion 512a with a shape corresponding to the outer edge shape of the PTP sheet 1 (see reference). Figure 6 ).

[0097] The waste cutting blade 513 works in conjunction with the waste cutting support 522 to cut the waste section 7. The waste cutting blade 513 is located downstream of the PTP film 6 in the conveying direction, which is further downstream than the sheet punching blade 512.

[0098] Furthermore, the so-called waste section 7 refers to the portion of the PTP film 6 located downstream of the PTP film 6 in the conveying direction, which is closer to the sheet-cutting blade 512. Therefore, the so-called waste section 7 basically refers to the portion of the PTP film 6 remaining after being cut by the sheet-cutting blade 512, etc., but the portion of the PTP film 6 that is not cut and is directly conveyed to the downstream side of the aforementioned conveying direction, which is closer to the sheet-cutting blade 512, is also included in the waste section 7.

[0099] Furthermore, the waste cutting blade 513 is configured such that it does not protrude further toward the waste cutting support portion 522 than the punching blade 512 in the direction of movement of the first component portion 51 (see reference). Figure 10 In this embodiment, the front end (lower end) of the waste cutting blade 513 and the front end (lower end) of the punching blade 512 are positioned at the same height along the moving direction of the first component 51. Alternatively, the waste cutting blade 513 may be configured to retract further away from the waste cutting support portion 522 than the punching blade 512 along the moving direction of the first component 51. Furthermore, the waste cutting blade 513 may also be configured to protrude further towards the waste cutting support portion 522 than the punching blade 512 along the moving direction of the first component 51.

[0100] The pressing part 514 is used to clamp the PTP film 6 between itself and the surface 5212 of the sheet punching support part 521 when cutting the PTP film 6. In this embodiment, two pressing parts 514 are provided, each of which is respectively provided in the aforementioned cavity 511a. Each pressing part 514 includes a spring 514a and a pressing pin 514b (see reference). Figure 7 In this embodiment, the spring 514a constitutes a "buffer mechanism".

[0101] Spring 514a is a coil spring capable of elastically deforming along the movement direction of the first component 51, and is inserted into the cavity 511a. Spring 514a is fixed between the base 511 and the pressing pin 514b. Thus, the pressing part 514 can elastically deform along the movement direction of the first component 51.

[0102] The pressing pin 514b is a rod-shaped part with a flat front end face (lower end face) and its base end face (upper end face) inserted into the cavity 511a. The pressing pin 514b is configured to guide the movement of the spring 514a through the base 511 (particularly the part forming the cavity 511a) when the spring 514a is elastically deformed. In addition, according to the cavity 511a as described above, the pressing pin 514b is provided at a position corresponding to the transport path of the end edge portion in the width direction of the PTP film 6. Furthermore, the front end face of the pressing pin 514b is formed to be opposite to the surface 5212 of the sheet punching support portion 521, which is located further downstream in the aforementioned transport direction than the punching hole 5211 described later.

[0103] In addition, the front end face of the pressing pin 514b protrudes further toward the sheet-cutting support portion 521 than the sheet-cutting blade 512 in the moving direction of the first component portion 51. As a result, when the first component portion 51 moves toward the second component portion 52, the front end face of the pressing pin 514b contacts the PTP film 6 before the sheet-cutting blade 512 contacts the PTP film 6.

[0104] In addition, the structure is configured such that, when the first component 51 is positioned in the aforementioned retracted position, the distance from the front end face of the pressing pin 514b to the conveying path of the PTP film 6 along the moving direction of the first component 51 is sufficiently larger than the distance from the waste cutting blade 513 to the waste cutting support portion 522 (particularly the waste support blade 522a described later) along the same moving direction. Therefore, when the first component 51 moves to the second component 52 side, the waste portion 7 can be cut by the waste cutting blade 513 and the waste support blade 522a before the front end face of the pressing pin 514b contacts the PTP film 6.

[0105] Next, the second component 52 will be described. The sheet-cutting support 521 is positioned opposite the sheet-cutting blade 512, separated from the PTP film 6, and has a punching hole 5211 with a shape corresponding to the outer edge shape of the PTP sheet 1. The punching hole 5211 opens onto the surface 5212 of the sheet-cutting support 521 (the surface located on the PTP film 6 side). Furthermore, in this embodiment, the surface 5212 of the sheet-cutting support 521 is a horizontal, flat surface, and the PTP film 6 is configured to be conveyed along this surface 5212 in a substantially horizontal direction by the aforementioned intermittent feed roller 32.

[0106] Furthermore, the sheet punching support portion 521 has an edge portion 5213 on the surface 5212 side that corresponds to the punching hole 5211. 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 5213a located downstream in the aforementioned transport direction and extending in a direction intersecting the transport direction of the PTP film 6 when viewed from above.

[0107] The waste cutting support portion 522 is located further downstream in the aforementioned conveying direction than the die-cutting support portion 521, and includes a portion, namely the waste support blade 522a, that works in conjunction with the waste cutting blade 513 to cut the waste portion 7. In this embodiment, the waste support blade 522a is formed by the end face (the surface parallel to the moving direction of the first component 51) of the waste cutting support portion 522 in the aforementioned conveying direction and the surface of the waste cutting support portion 522 (the surface located on the PTP film 6 side), and has a square shape. Alternatively, the waste support blade 522a may also have a shape that tapers towards the PTP film 6 side.

[0108] Furthermore, the scrap cutting support portion 522 is configured such that at least the scrap support blade 522a protrudes further toward the scrap cutting blade 513 side than the aforementioned surface 5212 of the sheet-cutting support portion 521 along the moving direction of the first component portion 51. In this embodiment, the height H of the scrap cutting support portion 522 relative to the surface 5212 of the sheet-cutting support portion 521 along the moving direction of the first component portion 51 (refer to...) Figure 8 The setting is 3mm to 8mm. Additionally, in... Figure 8 For ease of illustration, some of the shading lines have been omitted.

[0109] A membrane guide portion 523 is provided between the sheet punching support portion 521 and the waste cutting support portion 522, guiding the waste portion 7 through a path approaching the waste cutting blade 513. In this embodiment, the membrane guide portion 523 is constructed by an inclined surface 523a that is connected to the aforementioned surface 5212 of the sheet punching support portion 521 and slides through the waste portion 7 to guide the waste portion 7.

[0110] In addition, such as Figure 8 As shown, the angle θ1 of the angle between the inclined surface 523a and the imaginary surface VS containing the aforementioned surface 5212 is set to be 10° or more and 20° or less (more preferably 10° or more and 15° or less).

[0111] Furthermore, in a cross-section that is orthogonal to the aforementioned imaginary surface VS, parallel to the transport direction of the PTP membrane 6, and passing through the downstream edge portion 5213a, an imaginary line VL is drawn from the downstreammost portion Mp of the inclined surface 523a along the transport direction of the PTP membrane 6 to the downstream edge portion 5213a. At this time, it is set that among the angles formed by the imaginary line VL and the imaginary surface VS, the smaller angle θ2 is 5° or more and 20° or less (more preferably 5° or more and 15° or less). Additionally, for ease of illustration, angles θ1 and θ2 are shown in the accompanying drawings at angles larger than the aforementioned ranges.

[0112] Furthermore, in this embodiment, the PTP packaging machine 10 includes a control device 61 (see reference 1) capable of controlling the operation of various devices constituting the PTP packaging machine 10 (e.g., intermittent feed roller 32 and sheet cutting device 37, etc.). Figure 4 The control device 61 is configured based on a computer system equipped with a CPU (Central Processing Unit) for arithmetic operations and ROM (Read-Only Memory) and RAM (Random Access Memory) for data storage.

[0113] The control device 61 controls the operation of the sheet cutting device 37 in a manner that the first component 51 is positioned in the aforementioned retracted position during the transport of the PTP film 6 by the intermittent feed roller 32. On the other hand, the control device 61 controls the operation of the sheet cutting device 37 in a manner that the portion of the PTP film 6 that is to be cut by the sheet cutting device 37 (sheet cutting blade 512, etc.) (the portion that becomes the PTP sheet 1) is temporarily stopped between the sheet cutting blade 512 and the sheet cutting support portion 521 (see reference). Figure 9 , Figure 10 The operation of the first component 51 is controlled in a manner that corresponds to the inspection results sent from the inspection device 22.

[0114] More specifically, when the inspection device 22 determines that the portion of the PTP film 6 that is to be cut by the sheet cutting device 37 is defective, the control device 61 controls the operation of the first component 51 by moving it from the aforementioned retracted position to the aforementioned side-cutting position (see reference). Figure 11 Thus, the waste section 7 is cut off by the waste cutting blade 513 and the waste cutting support section 522 (waste support blade 522a) without punching the PTP film 6. Then, the control device 61 controls the operation of the first component 51 in a manner that moves back to the previously mentioned retracted position.

[0115] On the other hand, when the inspection device 22 determines that the portion of the PTP film 6 that is to be cut by the sheet cutting device 37 is qualified, the control device 61 controls the operation of the first component 51 in such a way that it moves from the aforementioned retraction position to the aforementioned two cutting positions. At this time, the first component 51 first reaches the aforementioned one-sided cutting position, thereby cutting the waste portion 7 (see reference 513) by the waste cutting blade 513 and the waste cutting support 522 before the pressing part 514 contacts the PTP film 6. Figure 11 ).

[0116] Then, the first component 51 moves further toward the second component 52, thereby clamping the PTP film 6 by the pressing part 514 (pressing pin 514b) and the surface 5212 of the cutting support part 521 before the cutting blade 512 contacts the PTP film 6 (see reference). Figure 12 As a result, the PTP membrane 6, which was originally floating above the surface 5212 due to the membrane guide section 523, is now in contact with the surface 5212 located around the punch hole 5211.

[0117] Then, the first component 51 moves further towards the second component 52, reaching the two aforementioned cutting positions. Thereby, the sheet-cutting blade 512 (blade portion 512a) is inserted into the cutting hole 5211, and the sheet-cutting blade 512 and the sheet-cutting support portion 521 cut the PTP film 6 (see reference). Figure 13 , Figure 14 Furthermore, after the PTP film 6 is clamped by the pressing part 514, the spring 514a deforms elastically, so as not to hinder the movement of the first component 51 toward the two aforementioned cut positions.

[0118] Then, the control device 61 controls the operation of the first component 51 in a manner that moves back to the previously retracted position. As the first component 51 moves to the previously retracted position, the pressing part 514 disengages from the PTP film 6, and the PTP film 6 returns to a state in which it is at least suspended from the downstream edge 5213a (see reference). Figure 15 Then, the control device 61 controls the operation of the intermittent feed roller 32 in a manner that conveys a certain amount of PTP film 6. At this time, the PTP film 6 is conveyed in a state in which it is at least floating from the downstream edge 5213a.

[0119] Subsequently, the first component 51 is controlled to perform actions corresponding to the inspection results of the inspection device 22 each time the PTP membrane 6 is temporarily stopped. As a result, selectively, the waste portion 7 is cut without punching the PTP membrane 6, or the PTP membrane 6 is punched and the waste portion 7 is cut. Furthermore, after each cutting of the waste portion 7 and punching of the PTP membrane 6, a certain amount of the PTP membrane 6 is conveyed in a state where it floats from the downstream edge portion 5213a.

[0120] As detailed above, according to this embodiment, at least when the first component 51 is positioned in the aforementioned retracted position, the PTP film 6 is lifted (departed) from the downstream edge 5213a by the film guide 523. Therefore, the PTP film 6 can be transported while lifted from the downstream edge 5213a. This effectively suppresses the PTP film 6 from getting stuck on the downstream edge 5213a, which is particularly problematic, and more reliably prevents the PTP film 6 from getting stuck on the sheet cutting support 521. Consequently, the PTP film 6 can be transported more smoothly, improving the operational stability of the PTP packaging machine 10.

[0121] Furthermore, especially in this embodiment, there is a corner-corresponding portion 9 (see reference) that remains after punching and corresponds to the outer corner of the PTP sheet 1. Figure 15 The risk of the portion facing forward in the forward direction getting stuck on the downstream edge 5213a is eliminated, but according to this embodiment, the corner portion 9 can be more reliably prevented from getting stuck on the downstream edge 5213a.

[0122] In addition, the portion of the waste cutting support 522 that works in conjunction with the waste cutting blade 513 to cut the waste portion 7 (waste support blade 522a) protrudes further toward the waste cutting blade 513 than the surface 5212 of the sheet punching support 521. Therefore, even if the first component 51 is configured such that the waste cutting blade 513 does not protrude from the sheet punching blade 512 along the moving direction of the first component 51, when the first component 51 is positioned in a one-sided cutting position (the position when only the waste portion 7 is cut), it is still possible to more reliably prevent the sheet punching blade 512 from contacting the PTP film 6. Thus, both miniaturization of the first component 51 and stable cutting of only the waste portion 7 can be achieved by moving the first component 51 to a one-sided cutting position. Furthermore, the design freedom related to the positional relationship between the waste cutting blade 513 and the sheet punching blade 512 can be further improved.

[0123] Furthermore, when the first component 51 moves from the retracted position to the two cutting positions to punch the PTP film 6, the PTP film 6 is clamped by the surface 5212 of the sheet punching support 521 and the pressing part 514 before the sheet punching blade 512 contacts the PTP film 6 (before reaching the two cutting positions). Thus, the PTP film 6, which was originally floating from the surface 5212 via the film guide 523, becomes in contact with the surface 5212. In this state, the first component 51 moves to the two cutting positions, thereby punching the PTP film 6. Therefore, compared to directly punching the PTP film 6 while it is floating from the surface 5212, it is possible to more reliably prevent the punching position from shifting. As a result, the product quality of the manufactured PTP sheet 1 can be improved.

[0124] At the same time, according to this embodiment, the PTP film 6 can be clamped by the pressing part 514 before the cutting blade 512 contacts the PTP film 6, and the first component 51 can be allowed to move further after clamping by the spring 514a provided in the pressing part 514.

[0125] Furthermore, the waste portion 7 is cut by the waste cutting blade 513 and the waste cutting support portion 522 before the pressing portion 514 contacts the PTP film 6. Therefore, when cutting the waste portion 7, no force is applied from the pressing portion 514 to the first component 51 in a direction that would hinder its movement. Thus, it is possible to suppress the increase of the load (torque, etc.) applied to the aforementioned drive mechanism that moves the first component 51.

[0126] Furthermore, the waste cutting blade 513 is configured such that it does not protrude further toward the waste cutting support portion 522 than the sheet cutting blade 512 in the direction of movement of the first component 51, thus allowing for a further reduction in the size of the first component 51 in its direction of movement. This enables more reliable miniaturization of the sheet cutting device 37. Furthermore, it allows for more effective suppression of various cost increases.

[0127] In addition, the membrane guide section 523 is a simple inclined surface 523a, which simplifies the structure of the membrane guide section 523. As a result, it is possible to more effectively suppress the increase of various costs.

[0128] Furthermore, 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 membrane 6 can be made to float more reliably from the downstream edge portion 5213a.

[0129] On the other hand, by setting angles θ1 and θ2 to 20° or less, or height H to 8 mm or less, it is possible to more reliably prevent excessive protrusion (height) of the waste cutting support 522 relative to the surface 5212 (imaginary surface VS) of the sheet cutting support 521. Therefore, compared to the stroke of the first component 51 when moving from the retracted position to a one-sided cutting position, it is possible to more reliably prevent an extreme increase in the stroke of the first component 51 when moving from the retracted position to two cutting positions. As a result, miniaturization of the sheet cutting device 37 can be achieved more effectively. Furthermore, it is possible to more effectively suppress the increase in load applied to the aforementioned drive mechanism that moves the first component 51.

[0130] Furthermore, as described in this embodiment, the technical aspect of causing the PTP film 6 to float from the downstream edge 5213a is particularly effective in a configuration where the surface 5212 of the sheet-cutting support 521 is a horizontal, flat surface, and the PTP film 6 is transported along this horizontal, flat surface. In this configuration, the PTP film 6 tends to sag towards the sheet-cutting support 521 due to its own weight, thus making it more likely that the PTP film 6 will get stuck on the downstream edge 5213a.

[0131] Furthermore, the implementation is not limited to the above-described embodiments; for example, the following may also be implemented. Needless to say, other application examples and modifications not illustrated are also possible.

[0132] (a) In the above embodiment, the pressing part 514 is configured to clamp the PTP film 6 between the surfaces of the sheet punching support part 5212 and the sheet punching support part 521, located downstream of the PTP film 6 in the transport direction, more so than the punching hole 5211. Alternatively, the pressing part 514 may be configured to clamp the PTP film 6 between the surfaces of the sheet punching support part 5212 and the surfaces that enclose the punching hole 5211 in the width direction of the PTP film 6, located downstream of the center of the punching hole 5211 in the transport direction.

[0133] Furthermore, the pressing part 514 does not necessarily need to have both a spring 514a and a pressing pin 514b. For example, the pressing part may only have a spring 514a, which is used to clamp the PTP film 6. In addition, regarding the cushioning mechanism, a part that can elastically deform along the moving direction of the first component 51 (e.g., a cushioning part made of foamed resin or an air cushion) may be used, or a cylinder that can extend and retract along the moving direction may be used. Furthermore, the pressing pin 514b may be replaced with a plate-shaped or rod-shaped part that extends along the width direction of the PTP film 6.

[0134] (b) In the above embodiment, the membrane guide portion 523 is formed by an inclined surface 523a. However, the membrane guide portion can be appropriately modified as long as it can guide the waste portion 7 through a path close to the waste cutting blade 513, forming a state in which the PTP membrane 6 floats from the downstream edge portion 5213a. Therefore, for example, the membrane guide portion can also be formed by a stepped portion that protrudes further towards the waste cutting blade 513 than the aforementioned surface 5212 of the sheet punching support portion 521, and a rotatable roller, etc. In addition, the membrane guide portion can also be stepped, for example.

[0135] (c) In the above embodiment, the PTP film 6 is configured to be conveyed in a generally horizontal direction along the horizontal surface 5212 at the location of the sheet-cutting support 521. However, the conveying direction of the PTP film 6 at the location of the sheet-cutting support 521 can also be appropriately changed. For example, the surface of the sheet-cutting support can be designed as a flat vertical surface, and the PTP film 6 can be conveyed in a generally vertical direction along this surface.

[0136] (d) The configuration of the PTP sheet 1 described in the above embodiments is only an example. For example, the number and arrangement of the pocket portions 2 of the PTP sheet 1 can also be appropriately changed.

[0137] (e) In the above embodiment, the PTP film 6 is configured to have a number of bag portions 2 arranged along its width direction corresponding to the amount of one sheet, but the configuration of the PTP film 6 is not limited to this. For example, the PTP film 6 may also be configured to have a number of bag portions 2 arranged along its width direction corresponding to the amount of two or more sheets.

[0138] Furthermore, in the above-described embodiment, the PTP film 6 is configured such that the portions that become PTP sheets 1 are arranged continuously without gaps along the long side direction of the PTP film 6, but it can also be configured such that the portions that become PTP sheets 1 are arranged at certain intervals along the long side direction of the PTP film 6.

[0139] (f) The above-described embodiment is specifically designed for the case where the contents are tablets 5, but there are no particular limitations on the type or shape of the contents. For example, it may also be constructed to contain food and electronic components as contents.
