On the other hand, the other ends of the upper and lower lever members are freely rotatably connected to the central lever member. the

And as shown in Figure 10, the other end of the suction port support shaft 57 located below is fixedly connected to one end of the cam follower 61, and the cam follower provided at the other end of the cam follower 61 then follows the shape of the cam. In the cam groove 62 of the plate 63. the

Cam plate 63 is installed on the frame freely movable on the vertical direction relative to packaging machine frame 15, and cam plate 63 is connected with the piston rod of displacement cylinder device 64 that is installed on packaging machine frame 15, displacement cylinder device The expansion and contraction of the piston rod 64 drives the cam plate 63 to be displaced in the up and down direction (the up and down directions in FIGS. 9 and 10 ). The distance between the pair of suction ports 55 is adjusted by moving the cam plate 63 up and down. the

The mouthpiece holding member 58 is mounted on the upper guide rail (predetermined path) 59 of the packaging machine frame 15 so as to be movable in the left-right direction (the left-right direction indicated by the arrow in FIG. 7 ). the

In addition, a servomotor 65 for a suction port connected to a driving wheel 66 and a driven wheel 67 are attached to the packaging machine frame 15 , and a belt 68 is wound between the driving wheel 66 and the driven wheel 67 . The driving wheel 66 connected to the suction port with the servo motor 65 drives the belt 68 connected to the upper end of the suction port holding part 58, and the suction port holding part 58 can move in the left and right direction along the guide rail 59. the

The mode of operation of the bag hanging device 11 of the packaging machine according to the embodiment of the present invention will be described. the

First, the cam plate 63 is moved downward by the operation of the displacement cylinder 64. At this time, the pair of suction ports 55 of the bag hanging device 11 changes from the combined state shown in R in FIG. The status of the location. In this state, the mouthpiece holder 58 stops moving (initial stop position). the

In the initial state where there is a predetermined gap between the pair of suction ports 55, the packaging bag 18 manufactured by the bag making device (1-7) is fed by the extraction and cutting device 7 so that the opening end of the bag 18 is located at the pair of suction ports. 55 for the position between the gaps. the

Then, the displacement cylinder device 64 is operated to move the cam plate 63 upwards, and the pair of suction ports 55 are displaced to the combined state shown in R in FIG. The state of the orientation clamp. In this state, the bag 18 is sucked from the upper and lower sides by the pair of suction ports 55 . the

Then, the suction nozzle servo motor 65 is operated to move the suction nozzle holding member 58 forward along the guide rail 59, and the pair of suction nozzles 55 are driven to move forward along the moving track T in FIGS. 7 and 10 . In this way, as the pair of suction ports 55 are shifted along the moving locus T from the combined state R to the separated state F, the packaging bag 18 supplied in the closed state is smoothly opened. the

The packaging bag 18 in the opened state is hung on the cylindrical type 38 of the cylindrical type replacement device 10 at the position F in FIG. 10 and remains on the cylindrical type 38 in the open state. the

Then, the suction operation of the pair of suction ports 55 is stopped and the displacement cylinder device 64 is operated to move the cam plate 63 downward, so that the pair of suction ports 55 are separated from the upper and lower sides of the bag 18 . In this state, the mouthpiece holding member 58 also stops at the forward movement position (movement stop position). the

Then, the suction port is operated with the servo motor 65, and the suction port holding member 58 is retracted along the guide rail 59, and the pair of suction ports 55 retreats along the moving track T, and the pair of suction ports 55 changes from the separated state to the combined state and returns to the original position. state, a cycle process of the bag hanging device 11 ends like this. the

As mentioned above, the bag hanging device of the packaging machine involved in the present invention moves the suction mouth holding part 58 back and forth along the predetermined path (59) and drives the cam plate through the displacement cylinder device 64 at the stop position of the suction mouth holding part 58. 63 is displaced, so that a pair of suction ports 55 can be switched between the combined state R and the far away state F, so that poor contact and wear can be reduced so that the bag 18 can be opened smoothly. the

Finally, the overall working method of the packaging machine involved in the present invention will be described. the

Each device of the packaging machine according to the present invention operates in the following process order to manufacture a packaged product 19 filled with a predetermined number of products 17 . the

(1) First, in the bag-making device (1-7) of the packaging machine, the tubular synthetic resin film 1A derived from the film roll 1, after winding around the dancer roller 3, is corrected by the bending correction device 4. The meandering of the film 1A is corrected, and finally, it is sent to the saddle forming device 5 . the

(2) In the bridging seam forming device 5, a bridging seam is processed on the film 1A for the convenience of tearing the packaged product 19 filled with a predetermined number of products 17. Riding the seam is processed along the conveying direction of the film 1A. the

(3) Next, send the film 1A processed with a seam to the bag-making heat-sealing device 6, and pass through a pair of heat-sealing components installed up and down in the bag-making heat-sealing device 6, on the film 1A and on the film 1A. The heat-sealed part is processed in the direction perpendicular to the conveying direction. There is a certain distance between the seal portions of the film 1A, that is, the interval of one bag is required to be formed. the

(4) Then, the film 1A processed with the seam and the sealing part is sent to the extraction and cutting device 7, and the film 1A is cut into the packaging bag 18 according to a predetermined length near the processed heat-sealed part. the

The cutting device 7 is pulled out to pull out the film 1A at predetermined intervals (intervals of one bag), and the film 1A processed with a bridging seam and a sealing portion is cut into a packaging bag 18 in which the upstream side is sealed and the downstream side is opened. the

(5) After that, the packaging bag 18 formed into a predetermined length by the extraction and cutting device 7 is sent to the bag hanging device 11, and then is supplied to the cylindrical type replacement device 10 by the bag hanging device 11. the

(6) At the same time, a predetermined quantity of products 17 for filling in the bag 18 is supplied to the cylindrical type replacement device 10 through the supply conveying device 8, the lifting device 10 and the cylindrical type replacement device 12, and the products are filled into the hanging sleeve In the packaging bag 18 on the cylindrical type 38 of the cylindrical type replacement device 10. the

(7) Then, the packaging bag 18 filled with a predetermined number of products 17 is pushed out by the pushing device 12 to the final heat-sealing device 13, and the final heat-sealing device 13 seals the opening side of the bag 18 containing a predetermined number of products 17 to Complete packaging product 19 . the

The packaged product 19 can be filled into the bag 18 by filling a predetermined number of products 17 stacked in the front-back direction as shown in FIG. 11 , or by filling a predetermined number of products 17 stacked in the up-down direction as shown in FIG. 12 to bag 18 for manufacture. the

(8) The packaged product 19 produced through the above steps is then discharged from the packaging machine through the discharge conveyor 14 . the

The packaging machine involved in the utility model is basically constituted as described above, however, it is not completely limited to the above-mentioned working method, and the various devices constituting the packaging machine can be appropriately changed according to needs, and the changed devices and work content are also included in this document. within the scope of protection of utility models. the
