Description

  The present invention relates to a PTP sheet manufacturing apparatus and a manufacturing system for manufacturing a PTP sheet, and more particularly to processing of a film end material after a PTP sheet is punched from a long PTP film by a punching apparatus.

  A PTP sheet in which tablets and the like are accommodated is manufactured by a PTP packaging machine (blister packaging machine). Specifically, a tablet is filled in a pocket portion formed in a long packaging film, and a cover film made of aluminum or the like is adhered to form a long PTP film. Then, after a slit or the like for separating the PTP sheet into small pieces is formed, the PTP sheet is manufactured by punching out the sheet unit by a punching device.

  As described above, according to the manufacturing method in which the PTP sheet is punched from the long film, it is necessary to process the film edge material generated after the PTP sheet is punched.

  For example, as shown in FIG. 3 (a), when punching is performed while slightly overlapping the punching position in the longitudinal direction (film transport direction) of the PTP film 21, a punching hole as shown by a two-dot chain line in the same figure. (Opening) 61 is formed, and the film end material 29n becomes three elongated strip-like films.

  Hereinafter, such a strip-shaped film edge material is described as a first type.

By the way, since a film end material is bulky, there existed the manufacturing apparatus of the PTP sheet conventionally equipped with the cutting device for cutting a film end material (for example, refer patent document 1). According to such a manufacturing apparatus, the film edge material is cut and processed relatively short in the film transport direction.
Japanese Patent Laid-Open No. 7-76306

  Incidentally, some of the PTP sheets are provided with V notches (V-shaped cuts) 7 on the side portions thereof, as in the PTP sheet 1v shown in FIG. The V notch 7 is provided in correspondence with the slit 6 for cutting the PTP sheet 1v into small pieces. Thereby, there exists a merit that isolation | separation in the slit 6 part becomes easy. In addition, the corners of the paired pieces after being cut off are rounded (not at right angles).

  However, when the PTP sheet 1v provided with the V notch 7 is punched, the punching position cannot be overlapped in the transport direction, unlike the case described above. Therefore, as shown in FIG. 3B, a punched hole 62 as shown by a two-dot chain line is formed in the film end material 29v after punching the PTP sheet 1v. The film as an end material remains not only in the width direction) but also in the left-right direction (film transport direction).

  Hereinafter, the film edge material in which the film remains on the top, bottom, left, and right of the punching hole will be described as a second type. The second type film edge material is generated not only when punching a PTP sheet provided with a V-notch, but also when the punching position is not overlapped in the film transport direction.

  And since the cutting device which the said conventional manufacturing apparatus comprises is a structure which cuts a film substantially perpendicular | vertical to a conveyance direction, it could not cut | judge the said 2nd type film end material finely. Therefore, the second type film edge material has a problem that it is bulky and difficult to handle.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a manufacturing apparatus and a manufacturing system for a PTP sheet capable of appropriately processing a film end material generated after punching a PTP sheet. And

  In the following, each means suitable for solving the above-mentioned purpose will be described in terms of items. In addition, the effect etc. peculiar to a corresponding means are added as needed.

Means 1. A punching means for punching a PTP sheet from a long PTP film in which a tablet is filled in a pocket portion formed in a packaging film and a cover film is attached so as to cover the opening of the pocket portion is provided. In the PTP sheet manufacturing equipment,
Conveying means for conveying a film end material which is the remaining part of the PTP film after the PTP sheet has been punched by the punching means;
An apparatus for producing a PTP sheet, comprising winding means for winding up the film edge material conveyed by the conveying means.

  In the PTP sheet manufacturing apparatus described in Means 1, the PTP sheet is punched from the long PTP film by the punching means. The long PTP film is formed by filling a tablet in a pocket portion formed in a packaging film and attaching a cover film so as to cover the opening of the pocket portion.

  In the means 1, in particular, the film end material generated after sheet punching is conveyed by the conveying means, and the film edge material is taken up by the winding means. Here, the film edge material is the remaining part of the PTP film after the PTP sheet is punched by the punching means (the same applies to the following means).

  When the punching position is not overlapped in the transport direction, a second type film edge material is generated in which the film remains on the top, bottom, left and right of the punching hole. In particular, when manufacturing a V-notch type PTP sheet, the punching position cannot be overlapped in the transport direction, so that this second type film edge material is always generated. And this 2nd type film edge material was not able to be cut finely with the conventional cutting device.

  In this regard, according to the means 1, since the film end material generated after the sheet punching is conveyed and wound up, the second type film end material can be wound and processed. Therefore, even if the second type film edge material is generated, the film edge material is not bulky. As a result, the second type film edge material can be appropriately processed.

Mean 2. Punching means for punching a PTP sheet from a long PTP film in which a tablet is filled in a pocket portion formed in a packaging film and a cover film is attached so as to cover the opening of the pocket portion;
In a PTP sheet manufacturing apparatus comprising a cutting means for cutting a film end material that is a remaining part of the PTP film after the PTP sheet is punched by the punching means,

In the cutting stop state by the cutting stop means, the film end material supplied to the cutting means passes through the cutting means and transports to the downstream side of the cutting means;
An apparatus for manufacturing a PTP sheet, comprising: a winding unit that winds up the film edge material conveyed by the conveying unit.

  Also in the PTP sheet manufacturing apparatus described in the means 2, the PTP sheet is punched out of the long PTP film by the punching means as in the case of the means 1 described above. Moreover, in the means 2, the film end material can be cut by the cutting means.

  When the punching positions are overlapped in the transport direction, a strip-shaped first-type film edge material is generated. Such a film end material can be wound up, but can be made into a relatively thin film piece by cutting it substantially perpendicularly to the conveying direction. In this regard, according to the means 2, the first type film edge material can be appropriately processed by providing the cutting means.

  In addition, in the means 2, the cutting stop means stops cutting by the cutting means, and in the cutting stop state, the conveying means passes the film end material supplied to the cutting means through the cutting means, and the cutting means To the downstream side. And a film end material is wound up by the winding-up means.

  When the punching position is not overlapped in the transport direction, as described above, a second type film edge material is generated in which the film remains on the top, bottom, left and right of the punching hole. And this 2nd type film edge material could not be cut | judged finely by the cutting means. In this respect, according to the means 2, the cutting by the cutting means is stopped, and in the state where the cutting is stopped, the film end material supplied to the cutting means is transported to the downstream side of the cutting means and wound. Therefore, the second type film edge material can be wound and processed, and the film edge material is not bulky. As a result, the second type film edge material can be appropriately processed.

  Since the cutting means and the winding means can be selectively operated in this way, the PTP sheet is produced by overlapping the punching positions up to the middle of the PTP film, and the first type film end material produced thereby The PTP sheet is manufactured without changing the punching position by changing the die and pitch for punching from the middle of the PTP film. It can be wound up and processed. On the other hand, until the middle of the PTP film, the PTP sheet is manufactured without overlapping the punching holes, the second type film end material is wound up, and the punching holes are overlapped from the middle of the PTP film. It is also possible to cut the first type film edge material.

  Moreover, the fact that the first and second types of film edge materials can be processed means that there is no restriction on the punching pitch, and there is a restriction on the die for punching that can be a factor of the pitch restriction. Means that there will be no more. That is, various types of PTP sheets can be manufactured by the same manufacturing apparatus. As a result, the user can enjoy extremely great advantages in terms of economy.

Means 3. In the PTP sheet manufacturing apparatus according to Mean 2,
The cutting means comprises a moving blade driven by a predetermined drive source,
The apparatus for producing a PTP sheet, wherein the cutting stop means comprises clutch means capable of connecting / disconnecting power from the drive source for driving the movable blade.

  According to the means 3, on the premise that the cutting means includes a moving blade driven by a predetermined drive source, the power from the drive source for driving the moving blade is generated by the clutch means included in the cutting stop means. Connected / disconnected. Therefore, it is not necessary to stop the drive source itself such as a motor, for example, and the drive source can be used for driving another mechanism (drive such as a punching means). As a result, since the number of drive sources can be reduced, the configuration of the manufacturing apparatus is simplified. Further, since control over the drive source is not required, the control configuration of the manufacturing apparatus is simplified.

Means 4. In the PTP sheet manufacturing apparatus according to any one of means 1 to 3,
In the manufacturing apparatus of the PTP sheet according to any one of claims 1 to 3,
The winding means is
A winding roller for winding up the film edge material;
A dancer roller capable of temporarily storing the film edge material conveyed intermittently on the upstream side of the winding roller;
An apparatus for manufacturing a PTP sheet, comprising: a feeding roller that feeds the film edge material stored by the dancer roller to the winding roller.

  In a manufacturing apparatus, usually, a film is intermittently conveyed in order to realize formation of a pocket portion or punching of a PTP sheet. For this reason, it is conceivable to take up the film edge material in accordance with the conveyance of the film, but the control for winding may be complicated. In this regard, according to the means 4, in the winding means, the film end material conveyed intermittently is temporarily stored by the dancer roller on the upstream side of the winding roller. Here, “storage” may be replaced with words such as stopping, stocking, and buffering. The same applies to the following means.

  Then, the stored film edge material is fed to the take-up roller by the feeding roller. In this way, it is not necessary to synchronize with the film transport timing on the upstream side, the configuration of the winding means is simplified, and the film edge material can be reliably wound.

  The following configuration may be adopted as a specific configuration when such a dancer roller and a feeding roller are provided.

Means 5. In the PTP sheet manufacturing apparatus according to any one of means 1 to 3,
A winding roller for winding up the film edge material;
A dancer roller provided to be movable in a predetermined direction in order to temporarily store the film edge material that is intermittently conveyed on the upstream side of the winding roller;
A feeding roller that feeds the film edge material stored by the dancer roller to the winding roller;

An apparatus for producing a PTP sheet, comprising: a feeding control means for stopping driving of the feeding roller and stopping feeding of the film end material when moved to a position.

  According to the means 5, the dancer roller moves in a predetermined direction so as to temporarily store the film end material intermittently conveyed on the upstream side of the winding roller. Then, the stored film edge material is fed to the take-up roller by the feeding roller. At this time, when the dancer roller moves to the first position due to the storage of the film edge material by the feeding control means, the feeding roller is driven to feed the film edge material. Further, when the dancer roller moves to the second position due to the feeding of the film edge material by the feeding roller, the driving of the feeding roller is stopped and the feeding of the film edge material is stopped. In this way, the feeding roller control by the feeding control means is based on the position of the dancer roller, and there is no need to synchronize with the film transport timing on the upstream side. As a result, the configuration of the winding means becomes relatively simple, and the film edge material can be reliably wound.

Means 6. In the apparatus for producing a PTP sheet according to means 4 or 5,
The winding roller includes a roller unit for winding the film edge material, and a driving force transmission unit that is driven by power from a predetermined driving source and rotationally drives the roller unit,
The driving force transmission unit constantly generates a torque necessary for winding up the film edge material fed by the feeding roller to the roller unit, and causes the roller unit to respond to a rotation state of the roller unit. An apparatus for manufacturing a PTP sheet, wherein the apparatus is configured to be relatively rotatable.

  According to the means 6, the driving force transmission part of the take-up roller is driven by power from a predetermined drive source, and the roller part for taking up the film end material is rotationally driven. The drive transmission unit constantly generates torque necessary for winding up the film edge material fed by the feeding roller to the roller unit. Further, it rotates relative to the roller portion according to the rotation state of the roller portion. That is, when the feeding of the film edge material is stopped, the roller portion cannot be rotated. In this case, only the drive transmission portion rotates. This eliminates the need for control over the drive source. In addition, since a constant torque is always generated in the roller portion, the film end material is hardly slackened, and the film end material can be wound more reliably.

Mean 7 In the PTP sheet manufacturing apparatus according to any one of means 1 to 6,
The transport means includes a non-rotatable fixed roller disposed so that a central axis thereof forms a predetermined angle with respect to a transport direction of the film edge material,
An apparatus for manufacturing a PTP sheet, wherein the film end material folded back along the circumferential surface of the fixed roller can be slid to change the transport direction of the film end material.

  Conventionally, in a manufacturing apparatus, a PTP sheet is punched while being conveyed in a predetermined direction, and a conveyor or the like is arranged in the predetermined direction in order to convey the punched PTP sheet to a subsequent process. Therefore, in the predetermined direction, it may be difficult to secure a space for arranging the winding means.

  In this regard, in the means 7, the conveying means includes a non-rotatable fixed roller disposed so that the central axis forms a predetermined angle with respect to the film edge material conveying direction. Then, the film end material folded back along the circumferential surface of the fixed roller is slid, and the conveyance direction of the film end material is changed. Therefore, an empty space such as a side portion of the manufacturing apparatus can be used effectively, and it is relatively easy to secure a space for arranging the winding means and the like.

Means 8. In the PTP sheet manufacturing apparatus according to means 7,

  The pockets filled with tablets are punched in sheet units by the punching means. However, the pocket portion located near the seam portion of the film is not filled with the tablet, and this portion is not punched. Therefore, a pocket part remains partially in a film end material. According to the means 8, since the film end material is hung on the circumferential surface of the fixed roller so that the surface of the film end material on the cover film side is in contact, there is a pocket portion remaining on the film end material. It is advantageous in that the pocket portion does not adversely affect the sliding of the film edge material and the conveyance direction can be appropriately changed.

  The above has been described as an invention of a manufacturing apparatus for a PTP sheet having a winding means, but can also be realized as an invention of a manufacturing system comprising a manufacturing apparatus and a film processing apparatus as shown below.

Means 9. PTP sheet provided with punching means for punching a PTP sheet from a long PTP film in which a tablet is filled in a pocket portion formed in a packaging film and a cover film is adhered so as to cover the pocket portion Manufacturing equipment,

That is, by providing the cutting means, the first type film edge material can be appropriately processed by the cutting means, and the second type film edge material can be wound and processed by the winding means. The second type film edge material can be appropriately processed. Further, during the production, the processing of the film edge material can be changed from cutting to winding, and conversely, from winding to cutting. Furthermore, since both the first and second types of film edge materials can be processed, various types of PTP sheets can be manufactured by the same manufacturing apparatus. As a result, the user can enjoy extremely great advantages in terms of economy.

  Of course, in the manufacturing system described in the means 9, the same configuration as that of the manufacturing apparatus shown in the means 3 to 8 can be adopted.

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

  First, two types of PTP sheets 1 and 1v that can be manufactured in the present embodiment will be described. FIG. 1A shows a normal type PTP sheet 1, and FIG. 1B shows a V notch type PTP sheet 1v provided with V notches 7 on both sides. FIG. 1C is an enlarged partial cross-sectional view common to both PTP sheets 1 and 1v.

  As shown in FIG. 1, each of the PTP sheets 1 and 1 v is formed on the container film 3 as a “packaging film” having a plurality of pocket portions 2 and the container film 3 so as to close the opening of the pocket portions 2. And a sealing film 4 as an attached “cover film”. The container film 3 is made of PP and has light transmittance (here, it is transparent). The sealing film 4 is made of aluminum.

  Each pocket portion 2 contains one tablet 5. The container film 3 of the PTP sheet 1 is formed with a plurality of horizontal slits 6 so as to be separated into, for example, a pair of small pieces including two pocket portions 2. Here, the V-notch type PTP sheet 1 v shown in FIG. 1B is provided with a V-notch 7 corresponding to the horizontal slit 6. Therefore, the V notch 7 facilitates separation at the horizontal slit 6 portion. Further, the corner portions of the paired pieces after being cut off are rounded (not at right angles) by the V notch 7.

  Next, the configuration of the PTP packaging machine (blister packaging machine) 10 as the “PTP sheet manufacturing apparatus” will be described.

  As shown in FIG. 2, on the most upstream side of the PTP packaging machine 10, a strip-shaped container film 3 is wound in a roll shape. The container film 3 wound in a roll shape is intermittently transported, and a heating device 12 and a pocket forming device 13 are sequentially arranged along the transport path of the container film 3. . The heating device 12 and the pocket forming device 13 constitute a pocket portion forming device 14. Then, the container film 3 is partially heated by the heating device 12, and the pocket portion 2 is formed on the container film 3 by the pocket forming device 13 in a state where the container film 3 becomes relatively flexible. The pocket portion 2 is formed at intervals between the container film 3 transport operations.

  A filling device 16, an appearance inspection device 17, and a sealing device 18 for automatically filling the tablet 5 with the tablet 5 are arranged along the transfer path of the container film 3 in which the pocket portion 2 is formed.

  The filling device 16 includes a rotary drum, and puts the tablet 5 into the pocket portion 2 formed in the container film 3.

  The appearance inspection device 17 is for inspecting whether or not the tablets 5 are filled in the respective pocket portions 2, whether there are any abnormalities in appearance such as chipping or cracking of the tablets 5, and the presence or absence of foreign matter. is there. The appearance inspection device 17 performs an inspection from the opening side of the pocket portion 2.

  On the other hand, the sealing film 4 formed in a belt shape is wound in a roll shape on the most upstream side. The drawing end of the sealing film 4 wound in a roll shape is guided toward the sealing device 18. The sealing device 18 includes a film receiving roll 19 and a heating roll 20, and the heating roll 20 can be pressed against the film receiving roll 19. And the container film 3 and the sealing film 4 are sent between both the rolls 19 and 20, and the container film 3 and the sealing film 4 pass between both the rolls 19 and 20 in a heating press-contact state. Thus, the sealing film 4 is adhered to the container film 3, whereby the band-shaped PTP film 21 in which the tablets 5 are filled in the pocket portions 2 is manufactured. At this time, a mesh-like protrusion for sealing is formed on the surface of the heating roll 20, and a strong seal is realized by strongly pressing it.

  An appearance inspection device 23 for detecting an abnormality of the tablet 5 or the like from the pocket portion 2 side is provided downstream of the sealing device 18. In addition, when a defective product is determined by the appearance inspection devices 17 and 23, a defective product signal is sent to a defective sheet discharge mechanism (not shown), and the PTP sheet 1 (1v) that has been determined to be defective is transferred by the defective sheet discharge mechanism. It is discharged separately and transferred to a defective hopper (not shown).

  A slit forming device 24 and a sheet punching device 26 as “punching means” are arranged in this order along the PTP film 21 transfer path downstream of the appearance inspection device 23. The slit forming device 24 has a function of forming the horizontal slit 6 at a predetermined position of the PTP film 21. The sheet punching device 26 has a function of punching the PTP film 21 in units of PTP sheets 1 (1v).

A conveyor 27 for transferring the punched PTP sheet 1 (1v) is provided below the sheet punching device 26, and the PTP sheet 1 (1v) is transferred to the finished product hopper 28. It has become so.

  By the way, although it has already been described that two types of PTP sheets 1 and 1v can be manufactured in the present embodiment, two types of film edge materials 29 are generated depending on which of the PTP sheets 1 and 1v is manufactured.

  In the present embodiment, as shown in FIG. 3, the PTP sheets 1 and 1v are punched two by two in the width direction of the PTP film 21, but in the case of the normal type PTP sheet 1 (FIG. 1 (a )), And punching is performed so that the punching positions slightly overlap in the film transport direction. Therefore, after the punching of the normal type PTP sheet 1, the film remains only in the vertical direction (film width direction) of the punching hole 61 indicated by a two-dot chain line in FIG. 3A, and a strip-shaped film end material 29n is generated. This is referred to as a first-type film edge material 29n.

  On the other hand, in the case of the V-notch type PTP sheet 1v (see FIG. 1B), since the V-notch 7 is formed, the punching positions cannot be overlapped in the film conveyance direction. Therefore, after the punching of the V-notch type PTP sheet 1v, the film in which the film remains in the up-down direction (film width direction) and the left-right direction (film transport direction) of the punching hole 62 shown by a two-dot chain line in FIG. End material 29v is generated. This is referred to as a second type film edge material 29v.

  Which type of PTP sheets 1 and 1v is manufactured can be obtained by exchanging the punching pitch by the sheet punching device 26 and the die for punching.

  The present embodiment is characterized by the processing of the first type or second type film edge material 29n, 29v after the PTP sheet 1 (1v) is punched out.

Further, FIG. 6 is an explanatory diagram showing a schematic configuration of the transport direction changing device 40. In addition, although the punched hole 62 (refer FIG.3 (b)) of PTP sheet 1v should exist in the film edge material 29v shown in FIG.4 and FIG.6, it omitted in order to avoid a figure becoming complicated. .

  The cutting device 30 is provided at the end of the PTP packaging machine 10 so as to correspond to the sheet punching device 26. In FIG. 4, the fixing mechanism of the cutting device 30 is omitted, but is fixed to the casing of the PTP packaging machine 10 using a bolt or the like. As shown in FIGS. 4 and 5A, the cutting device 30 includes a roller 31, a fixed blade 32, a moving blade 33, a motor 34 as a “drive source”, a clutch device 35, and a clutch lever 36. Yes.

  The fixed blade 32 is arranged on the downstream side of the roller 31 with a slight gap between the fixed blade 32 and the film end material 29. The movable blade 33 is disposed so as to face the fixed blade 32, and is configured to reciprocate in the contact / separation direction with respect to the fixed blade 32. With this configuration, when the movable blade 33 moves to a position close to the fixed blade 32, the film end material 29 is cut between the fixed blade 32 and substantially perpendicular to the transport direction.

  The motor 34 is for driving the roller 31 and the moving blade 33. Further, the clutch device 35 is interposed between the motor 34 and the movable blade 33 so that power for driving the movable blade 33 from the motor 34 can be connected / disconnected. The clutch lever 36 is for operating the clutch device 35 from the outside. When the power from the motor 34 is connected by the clutch device 35 by the operation of the clutch lever 36, the movable blade 33 performs the reciprocating motion. On the other hand, when the power from the motor 34 is cut by the clutch device 35, the movable blade 33 stops at a position separated from the fixed blade 32. Therefore, the clutch device 35 and the clutch lever 36 constitute “cutting stop means”, and the clutch device 35 constitutes “clutch means”.

  In the present embodiment, the strip-shaped first-type film end material 29n is processed by connecting the power from the motor 34 with the clutch device 35 by operating the clutch lever 36 and driving the movable blade 33 to cut it. To do. The cut film pieces are stored in a hopper (not shown).

  On the other hand, with respect to the second type film edge material 29v, the power from the motor 34 is cut by the clutch device 35 by the operation of the clutch lever 36, the moving blade 33 is stopped at the separated position, and the inside of the cutting device 30 Is passed as it is and conveyed downstream. A drawing roller 37 guides the second type film edge material 29v from the cutting device 30 and guides it to the downstream side. And the 2nd type film end material 29v is wound up by the winding device 50 through the conveyance direction change apparatus 40, as shown in FIG.

  Next, the winding device 50 will be described.

  As shown in FIGS. 4 and 5B, the winding device 50 includes a plate-like base portion 50a that is fixed and installed horizontally, and a back surface portion 50b that is erected on the back side of the base portion 50a. Become. A feeding motor 51, a winding motor 52, a feeding roller 53, a winding roller 54, a dancer roller 55, a lower sensor 56, and an upper sensor 57 are mainly disposed on the back surface portion 50b.

  The feeding motor 51 and the winding motor 52 are disposed on the back surface portion 50b so as to correspond to the transport path of the film edge material 29v. Each of the motors 51 and 52 is for driving a feeding roller 53 and a winding roller 54, which will be described later.

  The feeding roller 53 is rotatably supported at both ends by a pair of plate-like side wall portions 53a disposed and fixed at a predetermined distance. The rotating shaft of the feeding roller 53 protrudes toward the back side of the side wall 53a. The belt 51a of the feeding motor 51 is hung on the protruding portion.

  The winding roller 54 is disposed on the downstream side of the feeding roller 53, and a roller base end portion is supported on the back surface portion 50b. The winding roller 54 includes a roller portion 54a for winding the film edge material 29v, and a disk-like driving force transmission portion 54b disposed on the back side of the roller portion 54a. The driving force transmission unit 54b rotates about the same central axis as the roller unit 54a, and rotationally drives the roller unit 54a. A shaft portion 54c that is supported by the back surface portion 50b and rotates integrally with the driving force transmission portion 54b protrudes from the back surface side of the driving force transmission portion 54b. A belt 52a of the winding motor 52 is hung on the shaft portion 54c.

  The dancer roller 55 is disposed on the upstream side of the feeding roller 53, and both ends thereof are rotatably supported by the support portion 55a. The support portion 55a is slidably attached to a guide rail 55b that hangs in a substantially vertical direction from the side wall portion 53a. Thereby, the movement of the dancer roller 55 in the vertical direction along the vertical movement of the support portion 55a is derived.

  As shown in FIG. 5B, the lower sensor 56 and the upper sensor 57 are arranged corresponding to the movement path of the dancer roller 55. The lower sensor 56 is for detecting that the dancer roller 55 has been moved to the lower position as the “first position”, and the upper sensor 57 is that the dancer roller 55 has been moved to the upper position as the “second position”. It is for detecting.

  When the movement of the dancer roller 55 to the lower position is detected by the lower sensor 56, the feeding motor 51 drives the feeding roller 53 to feed the film end material 29v to the winding roller 54 side. It is configured as follows. On the other hand, the feeding motor 51 is configured to stop driving the feeding roller 53 when the upper sensor 57 detects the movement of the dancer roller 55 to the upper position. In this sense, the feeding motor 51 and the sensors 56 and 57 constitute “feeding control means”.

  Further, the winding motor 52 drives the driving force transmitting portion 54 b via the shaft portion 54 c of the winding roller 54. And the driving force transmission part 54b rotationally drives the roller part 54a. At this time, the driving force transmission portion 54b always causes the roller portion 54a to generate a torque necessary for winding the film end material 29v fed from the feeding roller 53. As a result, the film end material 29v fed from the feeding roller 53 is taken up. In addition, when the feeding of the film end material 29v from the feeding roller 53 is stopped and the roller portion 54a cannot rotate, the driving force transmission portion 54b rotates relative to the roller portion 54a.

  With this configuration, when the second type film end material 29v is supplied to the winding device 50, the dancer roller 55 is lowered, and the film end material 29v is stored (stocked) on the upstream side of the feeding roller 53. When the movement of the dancer roller 55 to the lower position is detected by the lower sensor 56, the stored film end material 29 v is fed to the winding device 50 side by driving the feeding roller 53 by the feeding motor 51. . Then, the fed film end material 29v is wound up by driving the roller portion 54a via the drive transmission portion 54b by the winding motor 52.

  When the film end material 29v is fed by the feeding roller 53, the dancer roller 55 is raised. When the upward movement of the dancer roller 55 is detected by the upper sensor 57, the driving of the feeding roller 53 by the feeding motor 51 is stopped. Then, the roller portion 54a cannot rotate, the drive transmission portion 54b rotates relative to the roller portion 54a, and the winding of the film end material 29v is interrupted.

  In this manner, the dancer roller 55 is repeatedly raised and lowered, and the film end material 29v temporarily stored by the dancer roller 55 is fed out. It is done.

  Next, the conveyance direction changing device 40 will be described.

  As shown in FIGS. 4 and 6, the transport direction changing device 40 is configured by a non-rotatable fixed roller 41. The fixed roller 41 has at least a surface made of polyacetal resin (may be a metal) and is arranged so that its central axis forms an angle of 45 degrees with respect to the conveying direction of the film end material 29v. The film end material 29v is hung on the fixed roller 41 from the lower side to the upper side of the fixed roller 41 so as to be folded along the circumferential surface of the fixed roller 41. Therefore, during conveyance, the roller slides on the circumferential surface of the fixed roller 41, whereby the conveyance direction of the film end material 29v is changed by 90 degrees. In addition, as described above, the sealing film 4 is adhered to the container film 3 by the sealing device 18 to produce the band-shaped PTP film 21, but the contact surface of the film end material 29 v with respect to the fixed roller 41 is It is the surface on the sealing film 4 side.

  As described in detail above, according to the present embodiment, by providing the cutting device 30, the strip-shaped first-type film edge material 29n (see FIG. 3A) is made substantially perpendicular to the film conveyance direction. It can be cut and processed into fine film pieces. Therefore, it can process appropriately, without making the 1st type film end material 29n bulky.

  On the other hand, the second type film edge material 29v (see FIG. 3B) is passed as it is without being cut by the cutting device 30, and is passed to the winding device 50 arranged on the downstream side of the cutting device 30. Can be rolled up. Therefore, the second type film edge material 29v can be appropriately processed without being bulky.

  As described above, according to the present embodiment, the cutting device 30 can function according to the type of the film edge material 29, or the winding device 50 can function by passing the cutting device 30.

  Therefore, until the middle of the PTP film 21, a normal PTP sheet 1 (see FIG. 1A) is manufactured, and the first type film edge 29n (see FIG. 3A) generated thereby is cut by the cutting device 30. The VTP notch type PTP sheet 1v (see FIG. 1B) is manufactured from the middle of the PTP film 21, and the resulting second type film edge 29v is processed by the winding device 50. It is also possible to do. Of course, on the contrary, until the middle of the PTP film, the second type film end material 29v is processed by the winding device 50, and from the middle of the PTP film, the first type film end material 29n is processed by the cutting device 30. It is also possible to do.

  Further, since the two types of film end materials 29n and 29v can be processed, both the normal type PTP sheet 1 and the V-notch type PTP sheet 1v can be manufactured by the same PTP packaging machine 10. Thereby, for example, because the second type film end material 29v cannot be processed, it is possible to avoid a situation where a dedicated packaging machine is newly purchased when the V-notch type PTP sheet 1v is manufactured. As a result, the user can enjoy extremely great advantages in terms of economy.

  Further, according to the present embodiment, the clutch device 35 is interposed between the motor 34 and the moving blade 33 in the configuration of the cutting device 30, and the power from the motor 34 for driving the moving blade 33 is connected. / Can be cut. For this reason, even when cutting by the cutting device 30 is stopped, it is not necessary to stop the driving of the motor 34, and the motor 34 can be used for driving another mechanism (driving the roller 31 in the present embodiment), for example. it can. Thereby, since the number of motors as a drive source can be reduced, the configuration of the PTP packaging machine 10 is simplified. Moreover, since the control with respect to the motor 34 becomes unnecessary, the control structure of the PTP packaging machine 10 becomes simple.

  Furthermore, according to the present embodiment, the film edge material 29 v supplied to the winding device 50 is temporarily stored using the dancer roller 55. Thereby, the film end material 29v can be reliably wound up without synchronizing with the conveyance timing of the film end material 29v. Further, at this time, the feeding control by the feeding motor 51 is based on the position of the dancer roller 55, and the control configuration of the winding means 50 is simplified, so that the winding device 50 can be configured relatively easily. .

  In addition, in the winding roller 54 on the downstream side of the feeding roller 53, when the roller portion 54a cannot rotate, the driving force transmission portion 54b rotates relative to the roller portion 54a. Thereby, control of the winding motor 52 becomes unnecessary, and the winding device 50 can be configured relatively easily in this respect. Further, the driving force transmitting portion 54b constantly generates torque necessary for winding on the roller portion 54a. As a result, the film end material 29v is less likely to be loosened, and the film end material 29v is reliably wound.

  By the way, in a PTP packaging machine, in order to punch a PTP sheet while transporting a PTP film in a predetermined direction and further transport the punched PTP sheet to a subsequent process, a conveyor or the like is arranged in the predetermined direction. Therefore, it is often difficult to secure an extra space in the predetermined direction.

  In this regard, according to the present embodiment, the conveyance direction of the film edge material 29v is changed by 90 degrees after passing the cutting device 30 by the conveyance direction changing device 40 (see FIGS. 4 and 6). Thereby, even if the winding device 50 is added to the configuration, it is relatively easy to secure the space, and there is no need to change the upstream configuration at all.

  Moreover, since the contact surface of the film end material 29v with respect to the fixed roller 41 of the transport direction changing device 40 is the surface on the sealing film 4 side, the pocket portion 2 that is not filled with the tablet 5 and not punched out is the film end. Even if it remains in the material 29v, the conveyance direction is reliably changed without being affected by the pocket portion 2 remaining in the film end material 29v.

  Although one embodiment has been described above, the present invention is not limited to such an embodiment, and various embodiments can be implemented without departing from the spirit of the present invention.

It is because it is also possible to provide only a film processing apparatus for the film end material processing of the conventional PTP packaging machine.

  (B) In the above embodiment, the second-type film edge material 29v is processed on the assumption that the V-notch-type PTP sheet 1v is manufactured, but the punching position in the film conveying direction regardless of the sheet shape. If the film is not overlapped, a film end material similar to the second type in which the film remains on the top, bottom, left and right of the punched hole is generated. The structure of the said embodiment is applicable also to such a film end material.

The driving force transmitting portion 54b is configured to always generate a torque necessary for winding at the roller portion 54a, so that the film end material 29v is less likely to be loosened. Further, when the roller portion 54a cannot rotate, only the driving force transmission portion 54b is configured to rotate, and the control of the winding motor 52 is unnecessary.

  On the other hand, the winding motor 52 directly drives the roller portion 54a without interposing the driving force transmission portion 54b, and the winding motor 52 is adjusted in accordance with the feeding of the film end material 29v by the feeding roller 53. Winding by the winding roller 54 may be performed in a controlled manner.

  (E) In the above embodiment, the film edge material 29v supplied to the winding device 50 by the dancer roller 55 is temporarily stored. However, the dancer roller 55 is not used and the intermittent conveyance timing of the film edge material 29v is used. The film edge material 29v may be wound up in synchronization.
