The raw material film supply unit 21 includes a bobbin 211 around which the raw material film F1 is wound, and a bobbin drive unit 212 that rotates the bobbin 211. The raw material film F1 is a transparent plastic film such as transparent polyvinyl chloride having a thickness of less than 0.1 mm. Further, the bobbin 211 is detachable from the bobbin driving section 212. This makes it possible to easily exchange the raw material film F1 for a different type.

  The heating device 31 has an upper mold 312 arranged vertically above the raw material film F1 and a lower mold 313 arranged vertically below the raw material film F1. The upper mold 312 and the lower mold 313 are formed in a plate shape from a metal having a high thermal conductivity, for example. Further, the heating device 31 drives the upper die 312 and drives the upper die 312 in the vertical direction, and the driving portion 315 that heats the lower die 313 and drives the lower die 313 in the vertical direction. And a device main body 311 supporting the parts 314 and 315. As shown by arrows AR11 and AR12 in FIG. 2A, the heating device 31 brings the heated upper mold 312 and lower mold 313 closer to the raw material film F1 from both sides in the thickness direction of the raw material film F1. Sandwich. As a result, the entire region P1 where the pocket Po1 is to be formed in the raw material film F1 is heated. Then, the heating device 31 heats the raw material film F1 for a preset time, and then separates the upper mold 312 and the lower mold 313 from the raw material film F1 as shown by arrows AR13 and AR14 in FIG. 2B. . Then, as shown by an arrow AR15 in FIG. 2B, the raw material film F1 is transported to the downstream side, and the formation-scheduled region P1 of the raw material film F1 moves into the forming device 32.

  The forming device 32 forms the band-shaped container film F2 by forming the pocket Po1 in the raw material film F1. The molding apparatus 32 has a first mold 324 arranged vertically above the raw material film F1 and a second mold 326 arranged vertically below the raw material film F1. The first mold 324 is provided with a plug (not shown) having an outer shape slightly smaller than the inner shape of the pocket Po1 to be formed in the raw material film F1 and a discharge hole (not shown) for discharging gas. There is. Here, the plug is arranged inside the discharge hole and can project to the outside of the discharge hole. Further, a heater (not shown) for suppressing the temperature decrease of the raw material film F1 is built in the plug. On the other hand, the second mold 326 is provided with a recess 326a corresponding to the outer shape of the pocket Po1 to be formed in the raw material film F1. Further, the molding device 32 includes a driving unit 322 that drives the first mold 324 in the vertical direction, a driving unit 325 that drives the second mold 326 in the vertical direction, and a gas supply unit that supplies gas (not shown). ) And a device main body 321 that supports the drive units 322 and 325 and the gas supply unit. The gas supply unit is connected to, for example, a compressor (not shown) provided in a factory in which a blister packaging machine is installed, and supplies gas to the discharge hole of the plug of the first mold 324. The first mold 324 and the second mold 326 may be appropriately changed depending on the depth of the pocket Po1 of the container film F2 to be generated and the area of the opening portion.

  The molding device 32 moves the second mold 326 vertically upward and moves the second mold 326 vertically upward as shown by an arrow AR17 in FIG. 3 in a state where the region P1 for forming the raw material film F1 is moved inside the molding device 32. The raw material film F1 is pressed against the first mold 324 by 326. As a result, the outer peripheral portion of the material film F1 that forms the pocket Po1 is clamped by the first mold 324 and the second mold 326. Then, the forming device 32 extends the raw material film F1 by causing the plug of the first mold 324 to protrude vertically downward by an amount of protrusion of, for example, more than 0% and less than 99% of the depth of the pocket Po1 to be formed. The amount of protrusion of the plug at this time may be appropriately adjusted according to the thickness distribution required for the pocket Po1 to be generated. For example, when the material film F1 is made of polyamide, polyethylene, or the like, the protrusion amount of the plug may be set to 70% ± 10% of the depth of the pocket Po1 to be generated. Then, the molding device 32 generates the container film F2 having the pocket Po1 by discharging gas from the discharge hole in a state where the plug is projected vertically downward.

  The first fixed chuck 43 includes a support portion 43a that supports the container film F2 from below vertically, a holding portion 43b that holds the container film F2 together with the support portion 43a from above vertically above the container film F2, and a holding portion 43b in the vertical direction.

This prevents movement of the container film F2 in the transport direction when the chuck portion 411 of the first chuck feed 41, which will be described later, does not sandwich the container film F2. Further, when the molding device 32 presses the raw material film F1 against the first mold 324 by the second mold 326, the portion P2 of the container film F2 located on the supply plate 51 is prevented from moving vertically upward.

  The supply plate 51 supports the container film F2 so that an operator can manually store the work in each of the pockets Po1 of the container film F2. The container film F2 is disposed above the upper flat portion of the supply plate 51. When the container film F2 is bent by the weight of the work when the worker supplies the work to the pocket Po1, the container film F2 is prevented from being excessively bent by coming into contact with the bottom of the pocket Po1 of the container film F2. There is.

  Returning to FIG. 1, the cover film supply unit 61 supplies the strip-shaped cover film F3. The cover film supply unit 61 includes a bobbin 611 around which the cover film F3 is wound and a bobbin drive unit 612 that rotates the bobbin 611. The cover film F3 is a metal sheet such as an aluminum sheet, a nonwoven fabric, a resin film, or the like. The cover film F3 supplied from the cover film supply unit 61 is superposed on the container film F2 at the receiving roller 64 so as to close the pocket Po1 of the container film F2. Further, the bobbin 611 is detachable from the bobbin drive unit 612. This makes it possible to easily replace the cover film F3 with a different type.

  The sealing device 71 seals the pocket Po1 by attaching the cover film F3 to the container film F2 while the work is accommodated in the pocket Po1 of the container film F2. The sealing device 71 is disposed on the downstream side of the receiving roller 64, is provided with a heating unit 713, and is disposed above the container film F2 and the cover film F3 in the vertical direction, and below the container film F2 and the cover film F3 in the vertical direction.

Further, when the punching device 81 presses the blister film F4 against the punch unit 812 by the die unit 813, the portion P3 of the blister film F4 located at the sealing device 71 is prevented from moving vertically upward.

  Returning to FIG. 1, the recovery unit 66 recovers the strip-shaped scrap F5 formed by punching out the blister pack BP from the blister film F4. The recovery unit 66 includes a bobbin 661 around which the scrap F5 is wound and a bobbin drive unit 662 that rotates the bobbin 661. The bobbin driving unit 662 attaches the bobbin 661 in the direction in which the scrap F5 is wound up with a force weaker than the force of holding the container film F2 by the first fixed chuck 43 and the force of holding the blister film F4 by the second fixed chuck 44. I am energetic.

  The first chuck feed 41 is disposed on the downstream side of the molding device 32, and holds the container film F2 from the thickness direction and intermittently conveys the container film F2 to the downstream side by a preset first reference distance. Further, the second chuck feed 42 is arranged on the upstream side of the punching device 81, and sandwiches the blister film F4 from the thickness direction to intermittently hold the blister film F4 downstream by a predetermined second reference distance. To move. Here, the second reference distance is, for example, the length of a region in the raw material film F1 in which the molding device 32 forms the pocket Po1 at one time, or the length of a portion of the blister film F4 corresponding to one blister pack BP. Set to equal distance. The first reference distance is set to 99% or more and less than 100% of the second reference distance. When the container film F2 is formed of a composite film of nylon and polyethylene, the first reference distance is preferably 99.85% ± 0.05% of the second reference distance.

  The first chuck feed 41 includes a chuck unit 411 that holds the container film F2, and a chuck moving mechanism 412 that moves the chuck unit 411 along the container film F2 feeding direction. As shown in FIG. 5A, the chuck portion 411 includes a support portion 411a that supports the container film F2 from below in the vertical direction, and a holding portion 411b that holds the container film F2 together with the support portion 411a from above in the vertical direction of the container film F2. , And a drive unit 411c that drives the sandwiching unit 411b in the vertical direction. The second chuck feed 42 has a chuck portion 421 that holds the blister film F4, and a chuck moving mechanism 422 that moves the chuck portion 421 along the feeding direction of the blister film F4. The chuck portion 421 drives the support portion 421a that supports the blister film F4 from below vertically, the holding portion 421b that holds the blister film F4 together with the support portion 421a from above vertically above the blister film F4, and the holding portion 421b in the vertical direction. And a drive unit 421c. The first chuck feed 41 and the second chuck feed 42 may sandwich a portion of the container film F2 and the blister film F4 over the entire width direction, or the container film F2 and the blister film F4 in the width direction. It is also possible to sandwich both ends of the. Alternatively, the first chuck feed 41 and the second chuck feed 42 may sandwich a part of the container film F2 and the blister film F4 in the width direction.

  Here, the operations of the first chuck feed 41 and the second chuck feed 42 will be described. First, it is assumed that the molding device 32 presses the raw material film F1 against the first mold 324 by the second mold 326, and at the same time, the punching device 81 presses the blister film F4 against the punch unit 812 by the die unit 813. In this case, the first fixed chuck 43 holds the container film F2 as shown by an arrow AR31 in FIG. 5 (A), and the second fixed chuck 44 as shown by an arrow AR33 in FIG. 5 (B). , Hold the blister film F4. At this time, the chuck portion 411 of the first chuck feed 41 appropriately moves to the upstream side of the container film F2 as shown by an arrow AR32 in FIG.

  Next, it is assumed that the molding device 32 separates the second mold 326 from the first mold 324, and at the same time, the punching device 81 separates the die unit 813 from the punch unit 812. In this case, the chuck portion 411 of the first chuck feed 41 clamps the container film F2 as shown by the arrow AR35 in FIG. 5B, and the chuck portion 421 of the second chuck feed 42 moves as shown in FIG. ), The blister film F4 is sandwiched. Thereafter, the first fixed chuck 43 releases the holding of the container film F2 as shown by an arrow AR34 in FIG. 5 (B), and the second fixed chuck 44 as shown by an arrow AR36 in FIG. 5 (B). Then, the holding of the blister film F4 is released.

  Subsequently, the chuck moving mechanism 412 of the first chuck feed 41 moves the chuck portion 411 to the downstream side at the first feeding speed as shown by an arrow AR38 in FIG. At the same time, the chuck moving mechanism 422 of the second chuck feed 42 moves the chuck portion 421 to the downstream side at the second feeding speed as shown by an arrow AR39 in FIG. Here, the movement distance of the chuck portion 411 is equal to the above-mentioned first reference distance, and the movement distance of the chuck portion 421 is equal to the above-mentioned second reference distance. As a result, the container film F2 and the blister film F4 are transported to the downstream side, as indicated by the arrow AR40 in FIG.

  After that, the first fixed chuck 43 holds the container film F2, and the second fixed chuck 44 holds the blister film F4. Next, the chuck portion 411 of the first chuck feed 41 releases the holding of the container film F2, and the chuck portion 421 of the second chuck feed 42 releases the holding of the blister film F4. Then, the chuck moving mechanism 412 moves the chuck portion 411 toward the upstream side of the container film F2, that is, in the direction toward the first fixed chuck 43. At the same time, the chuck moving mechanism 422 moves the chuck portion 421 toward the upstream side of the blister film F4, that is, toward the second fixed chuck 44.

  After that, the first chuck feed 41 and the second chuck feed 42 repeat the above-described series of operations, whereby the container film F2 and the blister film F4 are intermittently conveyed to the downstream side. Here, the second reference distance described above is longer than the first reference distance described above. Specifically, the ratio of the first reference distance to the second reference distance is 99% or more and less than 100%. As a result, in the supply plate 51 located between the first chuck feed 41 and the second chuck feed 42, it is possible to bring the container film F2 into a state in which an appropriate tension is applied.

  Returning to FIG. 1, the tension applying unit 23 supports the roller 231, an arm 232 that is long and has the roller 231 attached to one end in the longitudinal direction, and supports the arm 232 at the other end in the longitudinal direction of the arm 232.

As a result, the structure of the molding device 32, the sealing device 71, the punching device 81, etc. can be simplified as compared with a structure in which the container film, the blister film, etc. are conveyed by a chain clip conveyor, for example. The configuration of the entire packaging machine can be simplified. Further, since the container film F2 is conveyed in a state where both sides of the portion of the container film F2 located on the supply plate 51 are sandwiched between the first chuck feed 41 and the second chuck feed 42, the container film has a thickness of 0. Even if the film is softer than the polyvinyl chloride film of 1 mm, the occurrence of bending of the container film F2 in the supply plate 51 is suppressed. Therefore, it is possible to improve the workability of the worker who performs the work of filling the work into the pocket Po1 of the container film F2.

  By the way, for example, in a configuration in which a container film, a blister film, etc. are conveyed by a chain clip conveyor, a configuration in which the container film F2 and the blister film F4 are held by two chains from both sides in the width direction of the container film F2, the blister film F4. There is. In this configuration, elongation may occur in each of the two chains over time, and the amount of elongation may differ. In this case, there is a possibility that distortion may occur in the transport direction of the container film F2 and the blister film F4 due to the difference in the feed amount of the two chains. On the other hand, in the blister packaging machine according to the present embodiment, since the container film F2 and the blister film F4 are conveyed by the first chuck feed 41 and the second chuck feed 42, a chain including the two chains described above. Obstacles caused by the clip conveyor cannot occur.

  Further, the blister packaging machine according to the present embodiment has a simplified structure as compared with a configuration in which a container film, a blister film and the like are conveyed by a chain clip conveyor, for example. As a result, it is possible to relatively easily replace the various components that make up the blister packaging machine, for example, the first mold 324 and the second mold 326 of the molding device 32, and thus to manufacture a blister pack BP of a large variety in small quantities. Suitable for

  Further, the above-mentioned second reference distance according to the present embodiment is longer than the above-mentioned first reference distance. Accordingly, in the supply plate 51, it is possible to bring the container film F2 into a state in which an appropriate tension is applied. As a result, it is possible to improve the workability of the worker who fills the pocket Po1 of the container film F2 with the work on the supply plate 51.

  Further, the blister packaging machine according to the present embodiment is provided with the first fixed chuck 43, so that the upward movement of the portion P2 of the container film F2 located on the supply plate 51 is restricted. Therefore, it is possible to improve the workability of the worker who fills the pocket Po1 of the container film F2 with the work on the supply plate 51.

  Furthermore, since the blister packaging machine according to the present embodiment includes the second fixed chuck 44, the portion P3 of the blister film F4 located on the sealing device 71 is prevented from moving vertically upward. Therefore, it is possible to prevent the blister film F4 from unintentionally coming into contact with the upper mold 712 of the sealing device 71, so that damage to the blister film F4 is suppressed.

  Moreover, the blister packaging machine according to the present embodiment includes the tension applying units 23, 63, and 65. This maintains the tension applied to the raw material film F1, the cover film F3, and the blister film F4, so that the raw material film F1, the cover film F3, and the blister film F4 can be smoothly transported.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the configurations of the above-described embodiments. For example, as the raw material film F1 and the container film F2, a so-called hard film having a thickness equal to or harder than a polyvinyl chloride film having a thickness of 0.1 mm may be adopted.

  In the blister packaging machine according to the embodiment, the control device 90 allows the operator to appropriately change the ratio of the first reference distance to the second reference distance according to the type of the container film F2 (see FIG. (Not shown) may be included.

Is formed with a screw hole 23242c. Further, a groove 23242b communicating with the inside of the gas introduction pipe 23247 is formed at one end of the housing 23242.

  The connecting unit 23244 is a long rod and has a bar 23244b to which a pressing plate 23245 is attached at one end in the longitudinal direction, and a moving range of the bar 23244b which is arranged inside the housing 23242 and fixed to the other end of the bar 23244b. And a regulation plate 23244c that regulates. Further, the connection unit 23244 has a plurality of connection pins 23244a that connect the restriction plate 23244c and the fixed plate 23243. The plug 23249 has a plate-shaped plug body 23249a and a protruding portion 23249b protruding from the plug body 23249a. The projecting portion 23249b projects from the plug body 23249a in the thickness direction of the plug body 23249a. The plug 23249 is made of resin, for example, and is made using, for example, a 3D printer.

  The fixing plate 23243 is arranged in the housing 23242, and the plug body 23249a is detachably fixed to the other end of the housing 23242 in the cylinder axis direction, that is, the −Z direction side by the screw 23249c. The fixed plate 23243 is arranged so as to be relatively movable with respect to the housing 23242 in the cylinder axis direction of the housing 23242. The cover 23248 has a plate shape, and is detachably fixed to the other end of the housing 23242 in the cylinder axis direction with a screw 23248c. Further, the cover 23248 is provided with a through hole 23248a through which the tip of the projecting portion 23249b of the plug 23249 is inserted and a through hole 23248b through which the screw 23248c is inserted. The cover 23248 is inserted into the step portion 23242a of the housing 23242, and the shaft portion of the screw 23248c inserted into the through hole 23248b is screwed into the screw hole 23242c of the housing 23242, so that the housing 23242.

  The biasing member 23246 is, for example, a coil spring, and is interposed between the support portion 23241 and the pressing plate 23245. Then, when the pressing plate 23245 is moved in the −Z direction, the biasing member 23246 biases the pressing plate 23245 in the + Z direction, thereby connecting the fixing plate 23243 to the pressing plate 23245 via the connecting unit 23244. And the plug 23249 is biased in the + Z direction.

  Here, the operation of the molding apparatus including the plug unit 2324 will be described. The same components as those of the molding device 32 described in the embodiment will be described using the same reference numerals as in the embodiment. The forming device moves the plug 23249 vertically downward, that is, in the −Z direction to press the protruding portion 23249b thereof against the raw material film F1. At this time, the molding apparatus moves the second mold 326 vertically upward and arranges the second mold 326 in a position where it abuts on the plug unit 2324. Then, the molding apparatus discharges the compressed air in this state to generate the container film F2. Here, the driving unit 322 of the molding apparatus moves the pressing plate 23245 in the −Z direction to reduce the distance between the pressing plate 23245 and the supporting unit 23241. As a result, the fixed plate 23243 and the plug 23249 connected to the pressing plate 23245 via the connection unit 23244 move in the -Z direction, and the protrusion 23249b of the plug 23249 is in a state of protruding from the cover 23248. The drive unit 322 can change the protrusion amount of the protrusion 23249b of the plug 23249 by changing the distance between the pressing plate 23245 and the support unit 23241. Then, the tip portion of the protruding portion 23249b of the plug 23249 is in a state of protruding in the −Z direction from the through hole 23248a of the cover 23248. On the other hand, when the driving unit 322 releases the pressed state of the pressing plate 23245, the pressing plate 23245 moves in the + Z direction by the urging force of the urging member 23246. Along with this, the fixed plate 23243 and the plug 23249 connected to the pressing plate 23245 via the connection unit 23244 also move in the + Z direction. Then, the tip of the projecting portion 23249b of the plug 23249 is in a state of being sunk into the inside of the through hole 23248a of the cover 23248.

  Further, in the plug unit 2324 according to this modification, the cover 23248 can be removed from the housing 23242 by loosening the screw 23248c. Then, with the cover 23248 removed from the housing 23242, the plug 23249 can be removed from the fixed plate 23243 by loosening the screw 23249c. Therefore, for example, when manufacturing container films having different pocket shapes, it is only necessary to replace the plugs 23249 and the covers 23248 according to the different container films.

  According to this configuration, it is possible to produce a container film having different pocket shapes simply by exchanging the cover 23248 and the plug 23249. Therefore, for example, it is possible to reduce the load of replacement work of the plug unit 2324 when manufacturing a plurality of types of container films. Further, since it is not necessary to individually prepare the plug units 2324 corresponding to each of a plurality of types of container films, it is possible to reduce the management burden of the plug units 2324 and reduce the cost required for preparing the plug units 2324. You can

Further, through holes for removing the gas accumulated inside the recesses 23262a, 23263a, and 32264a in a state where the first mold and the second mold 2326 are abutted with the bottoms of the recesses 23262a, 23263a, and 23264a, respectively. 23262c, 23263c, and 23264c are formed. The sub molds 23262, 23263, and 23264 are arranged side by side along the Y-axis direction of the recess 23261e formed in the main body 23261. The sub metal molds 23262, 23263, and 23264 are fitted inside the recessed portion 23261e while being in contact with the outer peripheral portion of the recessed portion 23261d at the bottom of the recessed portion 23261e. A recess 23262b into which the protrusion 23261c of the main body portion 23261 is fitted is formed on both side walls in the Y-axis direction of the sub die 23262 arranged on the most −X direction side among the three sub die 23262, 23263, and 23264. ing. Accordingly, the sub molds 23263, 23264 can be accurately positioned with the sub mold 23262 as a reference. Note that the sub mold 23262 may be one in which the above-mentioned recess 23262b is not formed. The sub metal molds 23262, 23263, and 23264 are fixed by the screws 23265 that are screwed into the screw holes 23261b in a state where they are arranged inside the recesses 26261e. Then, the sub molds 23262, 23263, and 23264 can be detached from the main body portion 23261 by loosening the screw 23265. Note that at least one of the three sub molds 23262, 23263, and 23264 may be a block (not shown) in which the recess is not formed.

  A recess 23261d is formed on the bottom of the recess 23261e of the main body 23261. Then, in the state where the first mold and the second mold 2326 are butted against each other, among the gas discharged from the discharge holes of the first mold, the recesses 23262a, 23263a, 23264a of the sub molds 23262, 23263, 23264 are discharged. The gas accumulated inside collects in the recess 23261d through the through holes 23262c, 23263c, and 23264c. Further, the body portion 23261 is formed with a through hole 23261a having one end opening to the outer wall of the body portion 23261 and the other end communicating with the inside of the recess 23261d. As a result, the gas collected in the recess 23261d of the main body 23261 is discharged to the outside of the recess 23261e through the through hole 23261a.

  According to this configuration, a container film having different pocket shapes can be produced by simply replacing the sub molds 23262, 23263, and 23264. Therefore, for example, it is possible to reduce the load of replacement work of the second mold 2326 when manufacturing a plurality of types of container films.

  In the embodiment, a seal device having a lower mold including at least a main body and a sub lower mold detachable from the main body may be provided. For example, as shown in FIG. 9, the sealing device 2071 has a main body portion 27151 in which a concave portion 27151a is formed, and a sub lower mold 27152 in which a concave portion 27152a in which the pocket Po1 of the container film 2 is arranged is formed. .

A spacer 2719 is placed on the bottom surface 27151b of the recess 27151a of the main body 27151. By using the spacers 2719 having different thicknesses, the height H1 from the bottom surface 27151b of the recess 27151a to the upper surface 27152b of the sub lower die 27152 can be changed. Further, the inclination of the sub lower mold 27152 can be changed by changing the arrangement of the recess 27151a of the spacer 2719 on the bottom surface 27151b. The spacer 2719 may be, for example, a metal part such as a shim ring, or an elastic member made of an elastic material such as rubber. When the spacer 2719 is an elastic member, even if the height or the parallelism of the sub lower die 27152 is deviated, the spacer 2719 is elastically deformed so that the height or the parallelism of the sub lower die 27152 is not changed. It is possible to absorb the deviation.

  According to this configuration, the height H1 and the inclination of the sub lower mold 27152 can be changed by changing the thickness of the spacer 2719 and the arrangement of the recess 27151a on the bottom surface 27151b. Therefore, for example, when the container film F2 or the cover film F3 having different types of thickness is charged, only the thickness and arrangement of the spacer 2719 need be adjusted, and the load of the adjustment work of the sealing device 2071 is reduced.

The cutting unit 2812 has a Thomson blade 2812a having a U-shape in a plan view, as shown in FIG. Then, the punching device 2081 moves the cutting unit 2812 vertically downward with the blister film F2004 arranged between the lower die unit 2815 and the cutting unit 2812 so that the Thomson blade receives the tip end of 2812a. A blister pack (not shown) is punched from the blister film F2004 by pressing it against the plate 2815c. The shape of the Thomson blade 2812a included in the cutting unit 2812 is not limited to the above-described U-shape in plan view, but a shape having a plan view corresponding to the shape of the blister film F2004 punched out is adopted. . Here, the main body portion 2815b is made of resin, for example. In this case, the main body portion 2815b may be manufactured using, for example, a 3D printer. When the shape of the pocket Po2001 of the blister film F2004 is changed to a different shape, the body portion 2815b is changed to a different shape of the concave portion 2815d and the receiving plate 2815c is changed to a different shape of the through hole 2815e. It can be dealt with by changing to.

  According to this configuration, when the shape of the pocket Po2001 of the blister film F2004 is changed, only the main body portion 2815b and the receiving plate 2815c need be changed while leaving the base member 2815a as it is. Therefore, for example, it is possible to reduce the load required for exchanging the die unit 813 in the punching device 2081 when inserting various blister films F2004 having different shapes of the pockets Po2001.

Has been done. The recess 33262a is sized so that the head of the screw 33264 can be fitted therein. Then, as shown in FIG. 12A, the frame body 33262 is formed with a through hole 33262d penetrating from the bottom of the recess 33262a to the other surface side of the frame body 33262 and through which the shaft portion of the screw 33264 is inserted. There is.

  On one surface side in the thickness direction of the base member 33261, a recess 33261a into which any one of the plurality of frame bodies 33262 and the depth adjustment plate 33263 is fitted is formed. Further, a fixing hole 33261c for fixing the end of the positioning shaft 33265 and a screw hole 33261b with which the tip of the shaft of the screw 33264 is screwed are formed in the bottom of the recess 33261a in the base member 33261. There is.

  The depth adjustment plate 33263 has a flat plate shape and is arranged so as to overlap with the six frame bodies 33262, and by changing the positions of the six frame bodies 33262 in the stacking direction, portions corresponding to the openings 33262c of the frame body 33262. This is for adjusting the depth of the recess S3 formed in the. With the depth adjusting plate 33263 and the six frame bodies 33262 arranged in an overlapping manner, a recess S3 is formed on the side of the depth adjusting plate 33263 opposite to the base member 33261 side. A through hole 33263b is formed in the depth adjusting plate 33263 at a position corresponding to the through hole 33262b of the frame body 33262, which penetrates the depth adjusting plate 33263 in the thickness direction and into which the positioning shaft 33265 is inserted. . In addition, a recess 33263a having a size that allows the head of the screw 33264 to be fitted therein is formed at a position on the one surface side of the depth adjustment plate 33263 corresponding to the through hole 33262d of the frame 33262. Further, the depth adjusting plate 33263 is formed with a through hole 33263d penetrating from the bottom of the recess 33263a to the other surface side of the depth adjusting plate 33263 and into which the shaft portion of the screw 33264 is inserted.

  As shown in FIG. 12A, it is assumed that all of the six frame bodies 33262 are arranged on the side of the depth adjustment plate 33263 opposite to the base member 33261 side. In this case, a recess S3 having a depth equal to the thickness H21 when six frame bodies 33262 having a thickness H1 are stacked is formed on the side of the depth adjusting plate 33263 opposite to the base member 33261 side. However, the total thickness of the second die 3326 is a preset thickness H3. The thickness H1 can be set to 5 mm, for example. On the other hand, as shown in FIG. 12B, it is assumed that only three frame bodies 33262 out of the six frame bodies 33262 are arranged on the side of the depth adjustment plate 33263 opposite to the base member 33261 side. In this case, a recess S3 having a depth equal to the thickness H22 when three frame bodies 33262 having the thickness H1 are stacked is formed on the side of the depth adjusting plate 33263 opposite to the base member 33261 side. However, the total thickness of the second mold 3326 is equal to the preset thickness H3.

  As described above, in the second mold 3326 according to the present modification, by changing the position of the depth adjusting plate 33263 when the six frame bodies 33262 and the depth adjusting plate 33263 are overlapped, the depth of the recess S3 can be increased. Can be changed. Thereby, it is possible to change only the depth of the recess S3 while maintaining the thickness of the entire second die 3326 constant. As described above, by combining the six frame bodies 33262 and the depth adjusting plate 33263 with respect to one second mold 3326, the second mold 3326 having the recesses S3 of various depths can be prepared. That is, one second mold 3326 can be used to prepare the second mold 3326 having the recess S3 having a depth suitable for the size of the article to be packaged. Therefore, it is not necessary to prepare a plurality of types of second molds having different depths, and thus the preparation load of the second mold is reduced accordingly.

  According to this configuration, it is possible to change only the depth of the recess S3 while maintaining the overall thickness of the second mold 3326 constant, and thus the outer dimensions of the second mold 3326 having different recess depths. Can be shared. Therefore, there is an advantage that the mounting structure of the second mold 3326 in the molding device 32 can be simplified.

In the modification described above, the plurality of frame bodies 33262 and the depth adjustment plate 33263 are provided.
