Description

  The present invention relates to a blister packaging machine, and more particularly to a blister packaging machine configured so that both sides of a belt-shaped packaging film are conveyed by a clip chain conveyor.

  Generally, a blister packaging machine is used when manufacturing a blister pack (blister sheet). On the most upstream side of the blister packaging machine, a strip-shaped packaging film is wound into a roll. The packaging film wound in a roll shape is conveyed toward the downstream side, and along the conveyance path of the packaging film, the pocket portion forming means, the filling means, the sealing means, the punching / Cutting means are arranged in order. In the pocket portion forming means, a pocket portion for accommodating an object to be filled (workpiece) is formed. In the subsequent filling means, the work is put in and filled in the pocket portion. Further, in the sealing means, a cover film made of aluminum or the like is attached to a region (flange portion) where no pocket portion is formed in the container film. In the punching / cutting means, the blister pack as the final product is cut off by punching or cutting.

  By the way, the blister pack has a relatively small pocket portion such as a PTP sheet filled with tablets, and a relatively large pocket portion such as an electronic component, electronic device, food, medical device or the like. There is a great difference in the configuration of the blister packaging machine from the case of having it. That is, in the former case, since the pocket portion is relatively small, the packaging film is conveyed by the belt-shaped packaging film being hung on various conveying rollers and then being rotated. In this case, an accommodation recess for accommodating the pocket portion is formed on the outer peripheral surface of the roller, and it is possible to prevent a situation in which the pocket portion is crushed by accommodating the pocket portion in the accommodation recess, It is also used for detecting the position of the pocket.

On the other hand, in the latter case, that is, when a blister pack having a relatively large pocket portion is to be manufactured, a so-called chain clip conveyor is often used due to a situation in which an accommodation recess cannot be formed in the roller. The chain clip conveyor includes an endless chain and clips provided at predetermined intervals with respect to the chain. Then, the packaging film is transported by moving the chain in a state where both sides of the belt-like packaging film are held by clips (see, for example, Patent Document 1).
JP-A-11-147512

  By the way, in the blister packaging machine of the type which conveys the packaging film by the chain clip conveyor described above, the various processing means such as the pocket part forming means, the sealing means, and the punching / cutting means described above include a mold. . The mold is composed of an upper mold and a lower mold so as to sandwich a packaging film, and various processes are performed by moving at least one of them up and down. More specifically, the pocket portion is formed by the pocket portion forming means, the cover film is attached by the sealing means, and the blister pack is punched or cut by the punching / cutting means. And when a kind changes, a metal mold | die will be exchanged for another thing.

  However, conventionally, when replacing the mold, the space for attaching and detaching the upper mold and the lower mold is limited, and the upper mold and the lower mold must be lifted from above using a large lifter or the like. . For this reason, it takes a long time to replace the mold, resulting in a decrease in work efficiency. In particular, as represented by the punching / cutting means, when accuracy of alignment between the upper mold and the lower mold is required, the upper mold and the lower mold are assembled in a die set state. Some are installed. In this case, an operation for dividing the upper mold from the lower mold is also required. Further, once divided, it takes a considerable amount of time and skill to perform the positioning (assembly) operation again.

  The present invention has been made to solve the above-described problems, and the object thereof is required for a mold replacement operation in a blister packaging machine configured to transport a packaging film by a chain clip conveyor. An object of the present invention is to provide a blister packaging machine capable of shortening time and dramatically improving work efficiency.

  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 the means to respond | correspond as needed are added.

Means 1. A chain clip conveyor capable of transporting the packaging film in the longitudinal direction in a state where both sides of the belt-shaped packaging film are gripped,
A wall-like frame located on the front side and the back side of the chain clip conveyor;

On the other hand, by opening the opening / closing cover 27, the upper mold 31 and the lower mold 32 can be exposed at least on the near side.

  A support frame 35 is supported and fixed to the lower surfaces of the frames 18 and 19 in a suspended state by bolts or the like (not shown). The support frame 35 can be slid in the longitudinal direction of the chain clip conveyor 11 by loosening bolts and the like, and the position of the punching means 15 in the blister film 16 conveyance direction can be adjusted according to the product. ing. Four guide cylinders 36 are erected on the support frame 35, and support columns 37 are inserted along the guide cylinders 36 so as to be movable up and down. A lower plate 38 is connected to the lower end of the column 37, and an upper plate 39 is connected to the upper end of the column 37. On the lower surface of the upper plate 39, the upper die 31 having the above-described punching blade 33 is fixed with a bolt 41. On the other hand, an upper die driving cylinder 42 is mounted on the lower surface of the support frame 35. A rod 43 can be moved in and out of the upper mold driving cylinder 42, and the tip of the rod 43 is connected to the lower plate 38. Under such a configuration, when the rod 43 is in an immersive state, the lower plate 38, the support column 37, and the upper plate 39 are moved upward, whereby the upper die 31 is moved upward (standby state). On the other hand, when the rod 43 is in the protruding state, the lower plate 38, the support column 37, and the upper plate 39 are moved downward, whereby the upper mold 31 is moved downward and the blister pack 1 is punched out. The punched blister pack 1 is conveyed by a conveyor 17 provided on the lower side of the lower mold 32.

  A lower mold support plate 51 is supported via two links 52 and 53 above the center of the support frame 35. The lower link 52 is rotatably supported and fixed at the lower end portion thereof, and is connected to the lower end portion of the upper link 53 so as to be relatively rotatable by a connecting shaft 54 provided at the upper end portion. An upper end of the upper link 53 is connected to the lower mold support plate 51, and a rod (not shown) extending from a lower mold driving cylinder (not shown) is connected to the connection shaft 54.

  On the upper end surface of the lower mold support plate 51, the lower mold 32 having the above-described opening 34 is attached and fixed with a bolt (not shown). In the present embodiment, the conveyor 17 is also attached to the lower mold support plate 51. However, the present invention is not necessarily limited to such a configuration, and the conveyor 17 is the lower mold support plate 51. It may be independent.

  Guide cylinders 56 having guide holes 55 are formed to protrude at two locations on the front side of the lower mold 32. Further, a guide post 57 is fixed to the upper mold 31 in a suspended state. The lower end side of the guide post 57 is inserted into the guide hole 55 of the guide tube 56. A ball retainer (not shown) is provided between the inner peripheral surface of the guide hole 55 and the guide post 57. As a result, the relative sliding between the guide post 57 and the lower mold 32 is performed smoothly.

  On the other hand, guide cylinders 62 having guide holes 61 are formed to protrude at two locations on the back side of the lower mold 32. Further, a location pin 63 constituting a positioning pin is fixed to the upper mold 31 in a suspended state. The tip of the location pin 63 is tapered. The lower end side of the location pin 63 can be inserted into the guide hole 61. However, when the punching means 15 is stopped, that is, when the upper die 31 and the lower die 32 are separated (= standby state), the location pin 63 and the guide hole 61 (guide cylinder 62) are separated from each other. The chain clip conveyor 11 is configured to be positioned exactly at the height position (gap) between the location pin 63 and the guide hole 61.

  Under such a configuration, the rod of the lower mold driving cylinder (not shown) is in a protruding state, whereby the connecting shaft 54 is moved to the left side of the figure, and the pair of links 52 and 53 are bent in a dogleg shape as a whole. . As a result, the lower mold support plate 51 is moved downward, and the lower mold 32 is moved downward (standby state). On the other hand, when the rod of the lower mold driving cylinder is in an immersive state, the connecting shaft 54 is moved to the right side of the figure, and the pair of links 52 and 53 extend substantially linearly as a whole. As a result, the lower mold support plate 51 is moved upward, the lower mold 32 is moved upward, and the blister pack 1 is punched out. Of course, the lower mold 31 and the lower mold 32 are moved in synchronization.

  By the way, at the time of the punching, the upper mold 31 moves down and the lower mold 32 moves up, that is, both molds 31 and 32 move in a direction close to each other. The guide post 57 fixed in the suspended state slides relatively smoothly along the guide hole 55 of the guide tube 56 of the lower mold 32. At this time, the location pin 63 and the guide hole 61 that have been separated from each other approach each other, and the location pin 63 is inserted into the guide hole 61 from the tip side. Thus, while the guide post 57 and the location pin 63 are guided along the guide holes 55 and 61, the upper mold 31 moves down and the lower mold 32 moves up. As a result, accurate punching without positional deviation is performed.

  Next, regarding the punching means 15 configured as described above, a procedure for exchanging the upper mold 31 and the lower mold 32 will be described. When exchanging the upper mold 31 and the lower mold 32, the operation of all the means 12 to 15 including the punching means 15 as well as the chain clip conveyor 11 is stopped. When the punching means 15 is stopped, that is, when the upper mold 31 and the lower mold 32 are separated from each other, the location pin 63 and the guide hole 61 (guide cylinder 62) are separated from each other as described above. The chain clip conveyor 11 is located exactly at the height position (gap) between 63 and the guide hole 61. In this state, as shown in FIG. 5, the opening / closing cover 27 is opened, and the hand lifter 71 is positioned opposite the punching means 15. The hand lifter 71 is a lifter dedicated to mold replacement, and includes a carriage part 72, a mast part 73 erected from the carriage part 72, an elevating part 74 provided so as to be movable up and down with respect to the mast part 73, A pair of lifter arms 75 projecting forward from the elevating unit 74 and an operation unit 76 provided on the back side of the mast unit 73 are provided.

  Here, for convenience of explanation, although not described above, the upper mold 21 is formed with an insertion hole 81 as an attaching / detaching means that opens to the front side so as to correspond to the lifter arm 75 (FIG. 4). 6). Furthermore, a bolt hole 84 (for fastening and fixing a connecting post 82 (see FIG. 6) as a connecting means with a bolt 83 or the like is provided at an intermediate position between the pair of guide posts 57 on the near side of the upper die 31 and the lower die 32. Etc.) are provided.

  When the replacement is performed, first, as shown in FIG. 6, a connection support 82 is interposed between the upper mold 31 and the lower mold 32 and is fastened and fixed with a bolt 83 or the like. Thereby, the upper mold | type 31 and the lower mold | type 32 will be fixed by the connection support | pillar 82, and the relative movement of both 31 and 32 will be controlled reliably.

  Then, the lifter arm 75 is inserted into the pair of insertion holes 81 and inserted (see FIG. 5).

  Further, the bolt 41 that connects the upper plate 39 and the upper mold 31 is removed, and the bolt (not shown) that connects the lower mold support plate 51 and the lower mold 32 is removed. As a result, the upper mold 31 and the lower mold 32 can move relative to the upper plate 39 and the lower mold support plate 51 that have been supported so far. At the same time, the load of the upper mold 31 and the lower mold 32 is applied to the lifter arm 75.

  Then, as shown in FIG. 7, the hand lifter 71 is moved to the near side. At this time, since the upper surface 18a of the frame 18 on the near side is configured to be positioned below the lower surface of the lower mold 32, the lower mold 32 and the like do not hit the frame 18. In this way, the upper mold 31 and the lower mold 32 connected to each other by the connection support 82 and the like are easily removed from the front side. In addition, when attaching another upper mold | type and a lower mold | type, what is necessary is just to follow the procedure reverse to the above, and, thereby, a series of metal mold | die replacement | work operations are completed.

  As described above in detail, according to the present embodiment, when the upper mold 31 and the lower mold 32 are to be replaced, the frame 18 does not get in the way, and the upper mold 31 and the lower mold 32 are taken in and out from the front side. It becomes possible. For this reason, unlike the prior art in which the upper die and the lower die must be lifted from above using a large lifter or the like, the working time can be significantly shortened and the working efficiency can be dramatically improved. . In addition, since the replacement work can be performed at a relatively low position, it is not necessary to be aware of the space above. Therefore, there is a great merit in terms of space and a great contribution to safety.

  On the front side of the chain clip conveyor 11, the upper die 31 and the lower die 32 are connected by the guide post 57 and the connecting column 82, whereas on the far side of the chain clip conveyor 11, the location pin 63 and A guide hole 61 is provided. Then, the location pin 63 and the guide hole 61 are separated from each other, and the chain clip conveyor 11 is positioned exactly at the height position (gap) between the location pin 63 and the guide hole 61. For this reason, without removing the chain clip conveyor 11, the upper die 31 and the lower die 32 can be taken in and out while being connected. Therefore, the upper mold 31 and the lower mold 32 can be exchanged together. For this reason, the operation | work which divides | segments the upper mold | type 31 and the lower mold | type 32 apart, and the operation | work which assembles conversely can be eliminated. In particular, the upper die 31 is provided with a punching blade 33, and the lower die 32 has an opening 34, and skillful skills are required to assemble both dies 31, 32 once separated. In this embodiment, such a concern is useless.

  Furthermore, in this embodiment, the wall-shaped frames 18 and 19 are continuously extended along the longitudinal direction. That is, unlike the case where the frame is configured by erecting the support columns at predetermined intervals, the stability is further increased. In particular, in the present embodiment, the various means 12 to 15 are supported by the frames 18 and 19, but each means 12 to 15 can be more stably supported even in such a case. In particular, the punching means 15 is supported and fixed in a suspended state with respect to the frames 18 and 19. For this reason, the punching means 15 can be supported and fixed at a position as low as possible as compared with the case where it is placed and fixed on the frame. As a result, it is possible to suppress problems when the punching means 15 is located high (for example, it becomes difficult to perform maintenance work or a device for safety is required), and the lower space is effectively used. Can do.

  Further, the various means 12 to 15 and the chain clip conveyor 11 can be substantially isolated from the outside by the frames 18 and 19 and the opening / closing cover 27. For this reason, entry of foreign matter such as dust can be suppressed as much as possible. On the other hand, when separation is possible in this way, the space for exchanging the upper mold 31 and the like tends to be limited, but in the present embodiment, by opening the open / close cover 27, it is easy. The upper and lower molds 31 and 32 can be taken in and out. In this sense, it is possible to improve the workability at the time of changing the mold while suppressing the intrusion of foreign matters.
