pulleys

333 and 334 faces the rotary suction 32 from vertically below. Then, when the rotary suction 32 releases the chuck 322a of the chuck unit 322 arranged at the above-mentioned transfer position, the packaging pack BP held by the chuck unit 322 falls on the belt 331, and the pack transport device 33 Will be transferred to. As shown by the arrow AR41, the pack transport device 33 transports the package pack BP mounted on the belt 331 to the integration device 40 by moving the belt 331. At this time, the packaging pack BP is transported in a posture in which the pocket is vertically downward.

The integrating device 40 receives the reversing unit 49 and a plurality of (two in FIG. 16) packaging packs BP from the reversing unit 49 in an overlapping state, and transports the received bundles of the packaged packs BP to the sorting device 60. It has 34, 35 and. The reversing unit 49 includes an orbiting belt 41 in which transfer shelves 41a are projected at equal intervals on one surface side in the thickness direction, and a pulley 421 that is arranged inside the orbiting belt 41 and has the orbiting belt 41 wound around the peripheral surface.

pulleys

421 and 43. Further, the distance between two transfer shelves 41a adjacent to each other in the circumferential direction of the circulation belt 41 is set to be longer than the thickness of the packaging pack BP. As a result, the packaging pack BP is not sandwiched between the two transfer shelves 41a, and when the packaging pack BP is turned upside down, the packaging pack BP is sandwiched between the two transfer shelves 41a, so that damage to the packaging pack BP is suppressed. The pulley drive unit 422 includes, for example, a servomotor and a motor control unit that controls the servomotor, and the circumferential belt 41 has a distance corresponding to the length of two transfer shelves 41a adjacent to each other in the circumferential direction. The pulley 421 is driven so as to move intermittently.

The bundle transport unit 34 is preset with a belt 341 in which pin-shaped shaft bodies 341a are projected at equal intervals on one surface side in the thickness direction, and pulleys 342, 343, and 344 around which the belt 341 is wound. It has a pulley drive unit 345 that moves the belt 341 in the direction indicated by the arrow AR43 by rotationally driving the pulley 342 at a rotational speed. Here, at the timing when the two transfer shelves 41a of the reversing unit 49 are arranged at the preset transfer positions, the shaft body 341a is inserted into the slits of the two transfer shelves 41a of the reversing unit 49. Then, the bundle transfer unit 34 is a packaging pack placed on each of the two transfer shelves 41a by moving the belt 341 to the arrow AR43 in a state where the shaft body 341a is inserted into the slits of the two transfer shelves 41a. Push BPs out of them. At this time, the two packaging packs BPs placed on the two transfer shelves 41a are transferred to the belt 341 in a state of being overlapped with each other. Then, the bundle transport unit 34 transports the bundle composed of the two packaging packs BP in the direction indicated by the arrow AR43.

The bundle transfer unit 35 is a slider that collectively supports the arm 351 and the arm drive unit 352 that drives the arm in the vertical direction, the rail 354, the arm 351 and the arm drive unit 352, and is slidably suspended on the rail 354. It has 353 and. The rail 354 extends from the end of the bundle transfer unit 34 on the pulley 344 side to the sorting device 60 side. Here, when the bundle of the two packaging packs BP is conveyed vertically below the arm 351 by the bundle transport unit 34, the arm drive unit 352 moves the arm 351 vertically downward as shown by the arrow AR44. Insert the tip of 351 into the upstream side of the bundle of packaging pack BP. Then, with the arm 351 inserted into the upstream side of the bundle of the packaging pack BP, the slider 353 moves in the direction indicated by the arrow AR45, so that the bundle of the packaging pack BP is pushed out to the sorting device 60 side.

As shown in FIG. 17, the sorting device 60 receives a plurality of discs 61 having a circular shape in a plan view, a disc driving unit 62 for rotationally driving the discs 61, and a bundle of packaging packs BP loaded from the bundle transport unit 35 (FIG. 17). 17 has 8) baskets 63 and. Further, the sorting device 60 includes a stacking defect determination unit 65 that determines whether or not a stacking defect of the packaging pack BP has occurred based on the weight of the basket 63 in the received state of the bundle of the packaging pack BP, and a packaging pack BP. It has a recovery unit 64 for recovering a bundle or a packaging pack BP in which a poor accumulation of the above has occurred. The plurality of baskets 63 are arranged at equal intervals along the circumferential direction of the disc 61 at the peripheral portion of the disc 61, respectively. The accumulation defect determination unit 65 has a weight sensor (not shown), and when the weight of the basket 63 in the received state of the bundle of packaging packs BP is out of the preset reference weight range, the accumulation defect has occurred. Is determined. When the basket 63 has a function of holding a bundle of packaging packs BP received from the accumulating device 40 so that the stacking direction thereof is a preset direction, the accumulation defect determination unit 65 has a preset direction. Has a laser displacement meter that measures the thickness of the packaging pack BP in the above, and if the measured thickness of the bundle of packaging pack BP is outside the preset standard thickness range, it is determined that an accumulation defect has occurred. It may be.

The sorting device 60 receives a bundle of packaging packs BP extruded from the bundle transport unit 35 of the integrating device 40 as shown by an arrow AR45 at the transfer position Pos60. Then, the sorting device 60 moves the basket 63 that has received the bundle of the packaging pack BP to the delivery position Pos 61 that is delivered to the subsequent process by rotating the disc 61 in the direction indicated by the arrow AR61. Then, the bundle of the packaging pack BP is taken out from the basket 63 arranged at the delivery position Pos 61. On the other hand, when the sorting defect determination unit 65 determines that there is an accumulation defect, the sorting device 60 moves the basket 63 that has received the bundle of the packaging pack BP to the discharge position Pos 62 that discharges the bundle to the collection unit 64. Then, the sorting device 60 discharges the bundle of the package pack BP held in the basket 63 arranged at the discharge position Pos 62 or the package pack BP to the collection unit 64.

As described above, according to the packaging machine according to the present embodiment, in the work supply device 50, the gas discharge unit 55b directs the work W held inside the work feeder 53 toward the inside of the coil chute 54. Air is blown to the work W in the form of urging the work W. As a result, the work W held inside the work feeder 53 is smoothly introduced into the coil chute 54, so that the work W can be smoothly and quickly put into the pocket of the container film F2. As a result, the container film F2 can be transported to the downstream side at a relatively high speed, so that the production efficiency of the packaging pack BP in the packaging machine can be improved.

By the way, if the size or shape of the pocket of the packaging pack BP to be manufactured is different, the wheel 141a included in the transport portion 141 of the sealing device 14 needs to be replaced with the wheel 141a having the corresponding recess 141e. In this case, in the case of a structure in which the wheel 141a is fitted to the support shaft, the inner wall of the wheel 141a and the outer wall of the support shaft rub against each other every time the wheel 141a is replaced, and the inner wall of the wheel 141a or the outer wall of the support shaft is damaged. There is a risk. On the other hand, in the transport portion 141 of the sealing device 14 according to the present embodiment, as described above, between the side wall of the main body portion 1411c of the heat transfer member 141c and the inner wall of the cylindrical portion 1411a of the wheel 141a, P141. A gap is formed. As a result, when the wheel 141a is attached to and detached from the heat transfer member 141c, it is possible to prevent the inner wall of the wheel 141a from coming into contact with the side wall of the heat transfer member 141c, so that damage to the wheel 141a or the heat transfer member 141c can be suppressed. Further, in the transport portion 141 according to the present embodiment, since the region A141 in the heat transfer member 141c is kept watertight only from the main body portion 1411c and the lid portion 1412c fixed to the support shaft 141d, a sealing seal is unnecessary. be. Therefore, since it is not necessary to replace the sealing seal, the operating rate of the transport unit 141 can be increased accordingly, and the production efficiency of the packaging pack BP in the packaging machine can be improved accordingly.

Further, the head 1734 of the punching device 173 according to the present embodiment has a base 17341, a punching cutter 1735 erected on the base 17341, and a scrap cutting cutter 1737. The tip of the scrap cutting cutter 1737 extends in the + Y direction with respect to the tip of the punching cutter 1735. Then, when the portion of the pack film F4 facing the punching cutter is a non-defective product, the punching device 173 moves the head 1734 from the above-mentioned standby position Pos0 to the first position Pos1 to pack the packaging from the pack film F4. Punch out the BP and cut the scrap F5. On the other hand, when the portion of the pack film F4 facing the punching cutter 1735 is defective, the punching device 173 moves only the scrap F5 from the standby position Pos0 to the above-mentioned second position Pos2. Disconnect. Here, the distance ST1 from the standby position Pos0 to the first position Pos1 is longer than the distance ST2 from the standby position Pos0 to the second position Pos2. This eliminates the need for the process of sorting the packaging pack BP into non-defective products and defective products after punching the packaging pack BP from the pack film F4, thereby improving the production efficiency of the packaging pack BP in the packaging machine. Can be done.

Further, by using the punching device 173 according to the present embodiment, it is not necessary to provide a device for cutting the scrap F5 separately from the punching device 173, so that the packaging machine can be downsized accordingly. Can be done. Further, since the scrap F5 including the defective product of the packaging pack BP can be collected together with the other scrap F5 in the scrap collection unit 39, it is not necessary to separately provide a mechanism for collecting the defective product of the packaging pack BP. ..

Further, the rotary suction 32 according to the present embodiment is a drum 321 and a drum in which the chuck unit 322 for holding the packaging pack BP and the chuck unit 322 are arranged at any of the above-mentioned receiving position, imaging position and transfer position. It has a drive unit 323 and. Then, the imaging position and the transfer position are arranged in the vertical direction. As a result, for example, the imaging position for imaging the packaging pack BP by the visual inspection device 31 and the transfer position for transferring the packaging pack BP to the pack transfer device 33 are arranged in parallel in the Y-axis direction. The length of the packaging machine in the Y-axis direction can be shortened as compared with the above. Therefore, the size of the packaging machine can be reduced.

Further, according to the packaging machine according to the present embodiment, the film position changing portion 283 has a film guide 2831 arranged on the downstream side of the transport portion 281 to guide the pack film F4, and the pack film F4 of the film guide 2831. By changing the position of the pack film F4 in the width direction, the position of the pack film F4 in the punching device 173 in the width direction is changed. Further, the film position changing unit 26 changes the position of the pack film F4 in the slit forming device 171 by moving the guide roller 261 in the transport direction of the pack film F4 or the width direction of the pack film F4. Thereby, the slit position can be corrected in the transport direction or the width direction of the pack film F4 without providing a drive mechanism for moving the entire slit forming device 171 in the transport direction or the width direction of the pack film F4. .. Therefore, the packaging machine 1 can be downsized because it is not necessary to provide a drive mechanism for moving the entire punching device 173 or the slit forming device 171 in the transport direction or the width direction of the pack film F4.

Further, in the packaging machine according to the present embodiment, the position sensor 154 detects the amount of displacement of the mark provided on the cover film F3 from the preset reference position in the transport direction of the cover film F3, and adjusts the tension. The unit 153 adjusts the tension applied to the cover film F3 conveyed to the sealing device 14 based on the amount of misalignment detected by the position sensor 154. As a result, the occurrence of misalignment of the sticking position of the cover film F3 is suppressed, so that the appearance quality of the packaging pack BP can be improved.

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 shown in FIG. 18, the sealing device 2014 detects the temperature of the transport unit 141, the pressing unit 142, the preheating unit 2145 that preheats the cover film F3 immediately before the cover film F3 is transported to the transport unit 141, and the temperature detection. It may have a part 2146 and. In FIG. 18, the same reference numerals as those in FIG. 1 are attached to the same configurations as those in the embodiment. Further, the sealing device 2014 includes a roller 1441 and a roller 21442 that guides the cover film F3 supplied from the cover film supply unit 2015 to the preheating unit 2145. The cover film supply unit 2015 has a configuration in which a roller 21524 for guiding the cover film F3 delivered from the roller 1523 is added to the cover film supply unit 15 described in the embodiment.

As shown in FIG. 19, the preheating section 2145 includes a cylindrical heat transfer roller 2145a, a support member 2145b that supports the columnar heat transfer roller 2145a via two bearings 2145d, a support member 2145b, and a heat transfer. It has a heater 2145e that heats the roller 2145a and a heater 2145e. The heat transfer roller 2145a and the support member 2145b are each made of a material having high thermal conductivity such as metal. The support member 2145b is formed with a through hole 2145g that penetrates the inside of the support member 2145b along its central axis. The heater 2145e generates heat when an electric current is supplied from the control device 90. The heater 2145e is inserted into the through hole 2145g of the support member 2145b. Further, the preheating portion 2145 includes a lid portion 2145 c attached to one end portion of the support member 2145 b in the longitudinal direction, and a fixing member 2145 f attached to the other end portion of the support member 2145 b to fix the support member 2145 b to the packaging machine main body 99. , Have.

The temperature detection unit 2146 has, for example, a thermopile, detects the surface temperature of the heat transfer roller 2145a, and outputs a temperature detection signal indicating the detected surface temperature to the control device 90. Then, the control device 90 controls the current supplied to the heater 2145e so that the surface temperature of the heat transfer roller 2145a becomes a preset temperature based on the temperature detection signal input from the temperature detection unit 2146.

In the packaging machine according to this modification, when the cover film F3 does not need to be heated by the preheating unit 2145, the cover film F3 unwound from the roller 21524 is hung on the roller 1441 as shown by the alternate long and short dash line in FIG. , The cover film F3 is set to be conveyed directly to the conveying section 141 via the roller 1441. On the other hand, when it is necessary to heat the cover film F3 by the preheating section 2145, the cover film F3 unwound from the roller 21524 is hung around the roller 21442, so that the cover film F3 is conveyed after passing through the roller 21442 and the preheating section 2145. It is set to be transported by the route to the unit 141.

By the way, as a packaging pack BP, so-called childless packaging is provided in which the cover cannot be easily peeled off by infants, children, etc. In the production of such a packaging pack BP, a relatively thick cover film F3 is often used. Then, the temperature of the side of the cover film F3 to be attached to the container film F2 cannot be sufficiently raised only by heating by the heat transfer roller 1421 of the pressing portion 142, and the cover film F3 is attached to the container film F2. There is a risk of defects. On the other hand, it is conceivable that the temperature of the cover film F3 is raised by increasing the contact time between the cover film F3 and the heat transfer roller 1421 by lowering the transport speed of the container film F2 and the cover film F3. In this case, the time required for manufacturing the packaging pack BP becomes long, and the throughput decreases.

On the other hand, according to this configuration, since the cover film F3 is conveyed to the conveying unit 141 by the preheating portion 2145 and heated before being pressed by the pressing portion 142, it is attached to the container film F2 in the cover film F3. The temperature on the side can be raised sufficiently. Therefore, the occurrence of poor adhesion of the cover film F3 to the container film F2 is suppressed.

Further, according to this configuration, the transport path of the cover film F3 can be changed to a path that is heated by the preheating section 2145 and a path that is not heated by the preheating section 2145, so that there are many types of cover film F3 that can be used. There are also advantages.

In the embodiment, an example in which the packaging machine includes only the printing device 27 has been described. However, the present invention is not limited to this, and as shown in FIG. 20, for example, the packaging machine may include a printing device 27 and a laser marking device 3027 for printing on the pack film F4 using laser light. In FIG. 20, the same reference numerals as those in FIG. 1 are attached to the same configurations as those in the embodiment. In the packaging machine according to this modification, the laser marking device 3027 is installed on the + Z direction side of the packaging machine main body 99, and the portion of the packaging machine main body 99 where the laser marking device 3027 is installed is radiated from the laser marking device 3027.

Has. Further, in the packaging machine according to the present modification, the roller 3291 for guiding the pack film F4 unwound from the guide roller 261 of the film position changing portion 26 to the roller 3292 and the pack film F4 unwound from the roller 3293 are brought into the transport portion 281. It has a roller 3294 that guides the film feed roller 2811. Then, the laser marking device 3027 executes the marking process by irradiating the pack film F4 stretched between the two

rollers

3292 and 3293 with a laser beam. The packaging machine covers the entire portion including the two

rollers

3292 and 3293 on the −Z direction side of the laser marking device 3027 in the packaging machine main body 99, and the laser light emitted from the laser marking device 3027 and scattered by the pack film F4. A light-shielding cover (not shown) that blocks the light-shielding cover may be further provided.

In the packaging machine according to this modification, when printing on the pack film F4 by the printing device 27 is required, the pack film F4 unwound from the guide roller 261 of the film position changing portion 26 is fed as shown by the alternate long and short dash line in FIG. By directly hanging around the roller 1441 of the printing device 27, the pack film F4 is set to be transferred to the transport unit 281 after being printed by the printing device 27. On the other hand, when it is necessary to perform marking processing on the pack film F4 by the laser marking device 3027, the pack film F4 unwound from the guide roller 261 of the film position changing portion 26 is hung around the

rollers

3291, 3292, 3293, and 3294, respectively. , The pack film F4 is set to be transported to the transport unit 281 after being marked in a state of being stretched between the

rollers

3292 and 3293.

According to this configuration, the transport path of the pack film F4 can be changed to a path capable of printing by the printing device 27 and a path capable of marking processing by the laser marking device 3027, so that various packaging packs can be used. It has the advantage that it can be applied to the required use of BP.

In the embodiment, the gas discharge portion 55b communicates with the air flow path 55c of the fixing member 55 on one end side and opens in the through hole 55a of the fixing member 55 on the other end side, and is introduced into the air flow path 55c. An example of discharging the generated air into the through hole 55a has been described. However, the configuration of the gas discharge portion is not limited to this, and for example, the gas discharge portion communicates with the air flow path 55c on one end side and opens on the other end side in the through hole 55a of the fixing member 55. It may be composed of a plurality of flow paths. Alternatively, the gas discharge portion may have a nozzle (not shown) installed above the through hole 55a of the fixing member 55, and discharge the gas from the nozzle toward the inside of the through hole 55a.

In the embodiment, an example in which the packaging machine is provided with the rotary suction 32 has been described, but the imaging position and the pack transport device for imaging the packaging pack BP punched by the punching device 173 by the visual inspection device 31. A pack transfer device having another configuration may be used as long as it has a function of transferring to the transfer position to be transferred to 33. For example, the pack transfer device has an arm that is long and can be swiveled with one end as a fulcrum, a chuck provided at the other end of the arm, and an arm drive unit that swivels and drives the arm. You may. Then, the arm drive unit rotates the arm to punch the chuck, and the receiving position for receiving the packaging pack BP from the device 173, the imaging position for imaging the packaging pack BP by the visual inspection device 31, and the packaging pack. The BP may be arranged at any of the transfer positions for transferring to the pack transfer device 33.

In the embodiment, an example in which the visual inspection device 31 images the packaging pack BP while being held by the chuck unit 322 of the rotary suction 32 has been described, but the present invention is not limited to this, and is not limited to this, that is, the downstream side of the rotary suction 32, that is, , The packaging pack BP may be imaged during the period from the rotary suction 32 to the integration device 40. In this case, the visual inspection device 31 may image the packaging pack BP held on the image pickup stage having the chuck unit 4322, for example, as shown in FIGS. 21A and 21B. The imaging stage includes a stage main body 4321 and a chuck unit 4322 detachably fixed to the stage main body 4321. The chuck unit 4322 has a plurality of suction heads (six in FIG. 21B), a suction pad 4332 formed of an elastic material and attached to the tip of each of the plurality of suction heads 4333, and a plurality of suction pads in a rectangular box shape. It has a head support portion 4331 that collectively supports the head 4333 and is fixed to the stage main body 4321. Inside the suction head 4333, a tube 4333a that is maintained in a reduced pressure state when the packaging pack BP is sucked is provided. Further, inside the head support portion 4331, a pipe 4331a communicating with each of the pipes 4333a is provided. Further, a plurality of windows 4331b are provided on the side wall of the head support portion 4331. As a result, the workability of the operator who replaces the suction pad 4332 can be improved, and the weight of the head support portion 4331 can be reduced. Then, in a state where the chuck unit 4322 is fixed to the stage main body 4321, the pipe 4331a communicates with the exhaust pipe 4322b provided in the stage main body 4321 and connected to the vacuum pump (not shown). Further, at least a part of the suction pad 4332, the suction head 4333, and the head support portion 4331 is formed of, for example, resin.

By the way, the packaging pack BP may be delivered to the imaging stage in a warped state (curved state) as a whole. In this case, in the visual inspection device 31, the image pickup unit 311 is defocused, so that the captured image of the image pickup target portion in the package pack BP becomes unclear, and the mark provided on the package pack BP is recognized or packaged. There is a risk that the inspection for the presence or absence of foreign matter or dirt adhering to the pack BP cannot be performed accurately. Further, when measuring the length of the packaging pack BP using the photographed image captured by the visual inspection device 31, if the entire packaging pack BP is in a warped state, the length of the packaging pack BP can be accurately adjusted. Cannot be detected.

On the other hand, as shown in FIG. 21A, the chuck unit 4322 according to the present modification holds the packaging pack BP in a state of being sucked by a plurality of suction pads 4332. As a result, since the packaging pack BP can be flattened and then imaged by the image pickup unit 311, the sharpness of the photographed image obtained by the image pickup unit 311 can be improved. Therefore, it is possible to improve the accuracy of recognition of the mark provided on the packaging pack BP by the visual inspection device 31 or inspection of the presence or absence of foreign matter or dirt adhering to the packaging pack BP. Further, when the length of the package pack BP is measured using the photographed image captured by the visual inspection device 31, the length of the package pack BP can be detected with high accuracy.

In the embodiment, a laser displacement meter capable of measuring the three-dimensional shape of the surface of the packaging pack BP may be adopted instead of the visual inspection device 31.

Further, the control device 90 according to the embodiment may be arranged outside the packaging machine main body 99, or a part of the functions of the control device 90 is realized by the cloud server. You may.

In the embodiment, an example in which the position of the pack film F4 in the punching device 173 in the X-axis direction is changed by the film position changing unit 283 has been described. However, the present invention is not limited to this, and for example, the transport unit 281 changes the position of the pack film F4 in the X-axis direction by causing the film feed roller 2811 to move in the X-axis direction of the pack film F4 (not shown). ), And the transport unit 281 may function as a film position change unit. Then, in the printing device 27, when the pack film F4 is displaced in the X-axis direction in the transport unit 281, the position of the print head 272 may be moved in the X-axis direction accordingly.

According to this configuration, the number of parts can be reduced by omitting the film position changing portion 283, so that the packaging machine 1 can be simplified and downsized.

In the embodiment, the punching device can change the number of pockets Po1 contained in the packaging pack by changing the cutting position of the pack film after scrap punching in the direction orthogonal to the transport direction. May be good. In this case, the punching device performs an operation of punching the packaging pack after punching the scrap from the pack film.

For example, as shown in FIG. 22, the punching device 573 according to this modification has a die unit 5732 arranged on the + Y direction side of the pack film and a head 5734 arranged on the −Y direction side of the pack film. .. In FIG. 22, the same reference numerals as those in FIG. 12 are attached to the same configurations as those in the embodiment. The head 5734 includes a base 17341, a guide holding portion 17342, a punching cutter 5735 that is erected on the + Y direction side of the base 17341 and for punching scrap from the pack film, and a pack that cuts out a packaging pack by cutting the pack film. It has a film cutting cutter 5737 and. The pack film cutting cutter 5737 is arranged on the downstream side of the portion of the pack film on which the punching cutter 5735 faces, that is, facing the −Z direction side. That is, the pack film cutting cutter 5737 is erected on the + Y direction side of the base 17341 and on the −Z direction side of the punching cutter 5735. Here, the tip of the punching cutter 5735 extends from the tip of the pack film cutting cutter 5737 to the side opposite to the base 17341 side, that is, to the + Y direction side.

The die unit 5732 is a plate-shaped base 57321 having an opening 5732d formed in the center of the die unit 5732 for discharging scrap punched from the pack film in the + Y direction, and a guide member for guiding the pack film. It has 5739 and. An opening 5739d is also formed in a portion of the base 57321 facing the pack film cutting cutter 5737 of the head 5734. As a result, when cutting the pack film by bringing the pack film cutting cutter 5737 closer to the die unit 5732, the tip of the pack film cutting cutter 5737 is inserted inside the opening 5732b, and the pack film cutting cutter 5737 is inserted. It prevents the tip portion from coming into contact with the base 57321. The guide member 5739 has a U-shaped cross section like the guide member 1739 described in the embodiment, and has an opening 5739a through which a punching cutter 5735 of the head 5734 is inserted in the side wall, and a pack film cutting cutter 5737. An opening 5739d to be inserted is formed, and a groove (not shown) is provided on the + Y direction side. The groove side of the guide member 5739 is fixed to the base 57321, and a pack film is inserted between the groove of the guide member 5739 and the surface of the base 57321 on the −Y direction side. Further, a hole (not shown) through which the tip of the guide pin 1738 is inserted is bored in a portion of the guide member 5739 facing the guide pin 1738 of the head 5734.

As shown in FIG. 23, the sheet film F54 according to this modification is conveyed in the direction indicated by the arrow AR500. Then, the punching device 574 first punches the scrap portions at both ends of the sheet film F54 in the lateral direction by using the punching cutter 5735. After that, the punching device 574 cuts out the packaging pack by cutting the sheet film F55 from which the scrap has been punched along the lateral direction using the pack film cutting cutter 5737.

Here, the operation of the punching device 573 will be described with reference to FIGS. 24A to 25B. First, the punching device 173 moves the head 5734 from the preset standby position Pos0 to the third position Pos51, as shown by the arrow AR571 in FIG. 24A. Here, the standby position Pos0 is a position where the punching cutter 5735 and the pack film cutting cutter 5737 do not come into contact with the pack film F54. Further, the third position Pos51 is a position where the tip of the punching cutter 5735 is located on the + Y direction side of the pack film F54 and the tip of the pack film cutting cutter 5737 does not come into contact with the pack film F54. As a result, the scrap F55 is punched from the pack film F54 by the punching cutter 5735. Here, the punched scrap F55 is collected by a scrap collection unit (not shown). Next, the punching device 573 returns the head 5734 to the standby position Pos0 again as shown by the arrow AR572 in FIG. 24B, and the transport unit 281 connects the pack film F54 and the pack film F54 as shown by the arrow AR573. The film F56 is moved in the −Z direction. At this time, the transport unit 281 moves the pack film F54 so that the portion of the pack film F54 corresponding to the scrap F55 to be punched next is arranged on the + Y direction side of the punching cutter 5735 of the head 5734.

Further, when the packaging pack BP is cut out from the pack film F56, the punching device 573 moves the head 5734 from the above-mentioned standby position Pos0 to the fourth position Pos52 as shown by the arrow AR574 in FIG. 25A. Here, the second position Pos 52 is a position such that the tip end portion of the punching cutter 5735 and the tip end portion of the pack film cutting cutter 5737 are located on the + Y direction side of the pack film F54. As a result, the scrap F55 is punched from the pack film F54 by the punching cutter 5735, and the packaging pack BP is cut out from the pack film F56 by the pack film cutting cutter 5737. Here, the cut out packaging pack BP is transported to a subsequent process. Next, the punching device 573 returns the head 5734 to the standby position Pos0 again as shown by the arrow AR575 in FIG. 25B, and the transport unit 281 connects the pack film F54 and the pack film F54 as shown by the arrow AR576. The film F56 is moved in the −Z direction. At this time, the transport unit 281 moves the pack film F54 so that the portion of the pack film F54 corresponding to the scrap F55 to be punched next is arranged on the + Y direction side of the punching cutter 5735 of the head 5734.

Here, the punching operation of the punching device 574 according to this modification will be described with reference to FIG. 26. First, the transport unit 281 moves the pack film F54 by a distance Ls corresponding to the length of the scrap F55 in the transport direction in which the punching cutter 5734 can punch the pack film F54 at a time (step S501). ). Next, the moving distance of the pack film F54 immediately after the control device 9 starts transporting the pack film F54 or is cut by the pack film cutting cutter 5737 first is a distance Ls and a preset coefficient m (m is positive). It is determined whether or not it is equal to the distance corresponding to the product of (an integer of) (step S502). Here, the coefficient m corresponds to a number obtained by dividing the length of the pack films F54, 56 in the transport direction of the region corresponding to one packaging pack BP included in the pack films F54, F56 by the distance Ls. This coefficient m is changed according to the number of pockets Po1 contained in one packaging pack BP. When the control device 9 determines that the moving distance of the pack film F54 is shorter than the distance corresponding to the product of the distance Ls and the coefficient m (step S502: No), the punching device 574 moves the head 5734 by the distance ST51 in the + Y direction. (Step S503). As a result, only the scrap F55 is punched out from the pack film F54. On the other hand, when the control device 9 determines that the moving distance of the pack film F54 is equal to the distance corresponding to the product of the distance Ls and the coefficient m (step S502: Yes), the punching device 574 sets the head 5734 by the distance ST52 + Y. It is moved in the direction (step S504). As a result, the packaging pack BP is cut out from the pack film F54.

According to this configuration, packaging pack BPs of various lengths can be produced simply by changing the setting of the coefficient m. Therefore, for example, every time the length of the package pack BP to be produced changes, it is not necessary to replace the head and die unit according to the length of the package pack BP. Therefore, for example, it is possible to reduce the frequency of the work of exchanging the combination of the head and the die unit when manufacturing various packaging pack BPs having different lengths, so that the production efficiency of the packaging pack BP can be improved.

In the embodiment, the control device 9 changes the tension applied to the container film F2 by the tension adjusting unit 292 based on the image information obtained by imaging the packaging pack BP6 transmitted from the visual inspection device 31. The tension adjusting unit 292 may be controlled. Alternatively, the control device 9 controls the chuck feed 232 so as to change the feed amount of the container film F2 by the chuck feed 232 based on the image information obtained by imaging the packaging pack transmitted from the visual inspection device 31. It may be a thing.

For example, as shown in FIG. 27A, when the cover film F63 of the pack film F64 has a non-transparent seal portion CE1 and a transparent so-called non-seal portion NC1, when the pack film F64 is viewed in a plan view, The cover film F63 needs to be attached to the container film F2 so that the non-seal portion NC1 is located at the center of the pocket Po1. In this case, in the packaging pack BP6 punched out from the pack film F64, the non-seal portion NC1 is arranged in the central portion of the pocket Po1. On the other hand, for example, as shown in FIG. 27B, when the non-seal portion NC1 is displaced from the central portion of the pocket Po1 when the pack film F64 is viewed in a plan view, the non-seal portion is also in the packaging pack BP6 punched out from the pack film F64. NC1 shifts from the center of pocket Po1. In this case, there is a risk that the appearance may be judged to be poor in the process performed after the appearance inspection or the like. Therefore, the control device 9 according to this modification calculates the deviation amount and the deviation direction of the non-seal portion NC1 along the transport direction of the pack film F64 with respect to the pocket Po1 from the image information obtained by imaging the packaging pack BP6, and causes the deviation. When the amount exceeds a preset deviation amount, the feed amount of the container film F2 is changed so as to reduce the deviation amount.

Here, the container film feed amount adjusting process executed by the control device 9 according to this modification will be described with reference to FIG. 28. First, the control device 9 acquires a package pack image obtained by imaging the package pack BP6 transmitted from the visual inspection device 31 (step S601). Next, the control device 9 executes an edge detection process for detecting each of the peripheral portion of the non-sealed portion NC1 and the peripheral portion of the pocket Po1 based on the package pack image (step S602). Here, the control device 9 executes the edge detection process by using a well-known edge detection algorithm such as the Canny method or the Laplacian method.

Subsequently, the control device 9 shifts the non-seal portion NC1 with respect to the pocket Po1 along the transport direction of the pack film F64 based on the positions of the peripheral portion of the non-seal portion NC1 and the peripheral portion of the pocket Po1 detected by the edge detection process. The amount and the deviation direction are calculated (step S603). Here, the control device 9 specifies the position of the central portion of the non-seal portion NC1 from the position of the peripheral portion of the non-seal portion NC1 detected by the edge detection process, and the position of the peripheral portion of the pocket Po1 detected by the edge detection process. The position of the central portion of the pocket Po1 is specified from. Then, the control device 9 calculates the deviation amount and the deviation direction from the difference between the position of the central portion of the non-seal portion NC1 and the position of the peripheral portion of the pocket Po1. After that, the control device 9 determines whether or not the deviation amount | d6 | is equal to or greater than the preset deviation amount threshold value | d6 | th (step S604). Here, when the control device 9 determines that the deviation amount | d6 | is less than the deviation amount threshold value | d6 | th (step S604: No), the control device 9 executes the process of step S601 again. On the other hand, when the control device 9 determines that the deviation amount | d6 | is equal to or greater than the deviation amount threshold value | d6 | th (step S604: Yes), the deviation amount is reduced based on the calculated deviation amount and the deviation direction. The feed amount of the container film F2 to the transport section 141 is adjusted (step S605). Specifically, the control device 9 controls the tension adjusting unit 292 and adjusts the feed amount of the container film F2 to the conveying unit 141 by changing the tension applied to the container film F2 by the tension adjusting unit 292. do. Here, when the non-seal portion NC1 is displaced upstream with respect to the pocket Po1, the control device 9 controls the tension adjusting unit 292 so that the tension applied to the container film F2 is increased by the tension adjusting unit 292. Therefore, the feed amount of the container film F2 to the transport section 141 is reduced. On the other hand, when the non-seal portion NC1 is displaced to the downstream side with respect to the pocket Po1, the control device 9 controls the tension adjusting unit 292 so that the tension applied to the container film F2 is reduced by the tension adjusting unit 292. , Increase the feed amount of the container film F2 to the transport section 141.

Alternatively, the control device 9 may control the chuck feed 232 to adjust the feed amount of the container film F2 by the chuck feed 232 to the transport unit 141. In this case, when the non-seal portion NC1 is displaced upstream with respect to the pocket Po1, the control device 9 controls the chuck feed 232 so that the feed amount of the container film F2 by the chuck feed 232 becomes small. On the other hand, when the non-seal portion NC1 is displaced downstream with respect to the pocket Po1, the control device 9 controls the chuck feed 232 so as to increase the feed amount of the container film F2 by the chuck feed 232.

The image used by the control device 9 to calculate the deviation amount and the deviation direction of the non-seal portion NC1 with respect to the pocket Po1 along the transport direction of the pack film F64 is limited to the packaging pack image transmitted from the visual inspection device 31. It's not something. For example, an image pickup device (not shown) for imaging the pack film F4 is arranged at an arbitrary position on the downstream side of the seal device 14, and the control device 9 obtains a pack obtained by imaging the pack film F4 with this image pickup device. The film image may be used to calculate the amount of deviation and the deviation direction of the non-seal portion NC1 with respect to the pocket Po1 along the conveying direction of the pack film F64.

According to this configuration, in particular, when the cover film F63 of the pack film F64 has a non-transparent seal portion CE1 and a transparent so-called non-seal portion NC1, the pack film F64 is non-seal along the transport direction. The amount of deviation of the partial NC1 with respect to the pocket Po1 can be reduced. Therefore, the yield of the packaging pack BP6 punched out from the pack film F64 can be improved, and the production efficiency of the packaging pack BP6 can be increased accordingly.

In the embodiment, as shown in FIGS. 29A and 29B, for example, the molding apparatus 7012 attaches two

film detection sensors

7128A and 7128B at the outlet portion of the container film F2 to detect both ends of the container film F2 in the width direction. It may be provided. Then, on the upstream side of the molding apparatus 7012, a roller 71155 around which the raw material film F1 is wound and movable in the rotation axis direction thereof and a roller drive unit 71156 for driving the roller 71155 in the rotation axis direction are provided. You may. Here, the

film detection sensors

7128A and 7128B each emit a light source 71281 having a plurality of laser diodes or LEDs arranged in parallel in the width direction of the container film F2 and a photodiode radiated from the light source 71281 in parallel in the width direction of the container film F2. It has a light receiving unit 71282 that receives the light to be received. Further, the two

film detection sensors

7128A and 7128B are arranged at two locations separated by a preset distance in the width direction of the container film F2. This distance is set to be longer than, for example, the width of the container film F2 by a preset length. Further, the

film detection sensors

7128A and 7128B detect the amount of protrusion of the end portion of the container film F2 from the preset reference position, that is, the amount of deviation of the container film F2. Then, when the

film detection sensors

7128A and 7128B each detect the end portion of the container film F2, they transmit a film detection signal reflecting the amount of deviation of the container film F2 to the control device 9. On the other hand, when the film detection signal is input from either the

film detection sensor

7128A or 7128B, the control device 9 transmits the film detection signal from the film detection sensor (for example, 7128A) that does not transmit the film detection signal. The direction toward the sensor (for example, 7128B) is determined as the deviation direction of the container film F2, and the deviation amount of the container film F2 is determined based on the film detection signal. Here, when the film detection signal is input from the film detection sensor 7128A, the control device 9 determines that the deviation direction of the container film F2 is the + X direction, and when the film detection signal is input from the film detection sensor 7128B. , It is determined that the deviation direction of the container film F2 is the −X direction.

Further, the roller drive unit 71156 drives the roller 71155 around which the raw material film F1 conveyed to the molding device 7012 is wound based on the control signal input from the control device 9, thereby driving the raw material in the direction of the central axis thereof. The position of the raw material film F1 in the width direction of the film F1 with respect to the molding apparatus 7012 is changed. Here, the control device 9 determines the deviation direction and the deviation amount of the container film F2 based on the film detection signals received from the

film detection sensors

7128A and 7128B. Then, the control device 9 controls the roller drive unit 71156 so as to drive the roller 71155 in the direction in which the deviation amount of the container film F2 is reduced along the central axis direction thereof based on the determined deviation direction and the deviation amount. ..

According to this configuration, it is possible to suppress the occurrence of the misalignment of the pocket Po in the container film F2 due to the misalignment of the raw material film F1 in the width direction.

In the embodiment, an example in which the gas discharge unit 55b discharges the air supplied from the air source AG has been described, but the discharged gas is not limited to air, and other types such as nitrogen gas are used. It may be a gas of.
