No. 25, there is a vacuum gas replacement method in a food packaging machine and Japanese Patent Application Laid-Open No. 8-169416 discloses a method of degassing a packaging bag of a bag packaging machine. The former describes that a rotary table having a vacuum chamber is provided adjacent to a rotary table type filling machine, and the remaining air in the packaging bag after filling the contents is sucked together with the vacuum chamber. The latter describes that steam is used to replace the air in the bag with steam, and then the mouth is sealed.

Therefore, there is a problem that it takes a lot of power and a lot of time to evacuate the packaging bag. In the latter, since the opening of the bag is closed after the steam blowing nozzle is withdrawn, there is a problem that air flows into the bag again.

ある。SUMMARY OF THE INVENTION According to the present invention, a packaging bag to be conveyed is suspended and faced sequentially at each work station provided around a circular table. In an intermittent rotary filling and packaging machine in which the opening of the packaging bag is closed by heat sealing and carried out, an air suction nozzle is inserted into the packaging bag through the opening of the packaging bag filled with the contents. A sponge-like flexible holding bar presses and closes the opening together with the air suction nozzle from both sides to suck air in the packaging bag, and then pulls up the tip of the air suction nozzle to a position between the holding bars. Thus, the lower end of the nozzle is closed by pressing and closing the opening, and the opening below the pressing bar is sealed by heat sealing to solve the problem.

よって実行される。As shown in FIG. 1, a non-rotating cam disk 11 is mounted on the center of the circular table 2 in a replaceable manner.
The cam disk 11 is provided with an endless cam groove 12 that extends and shortens the distance from the center so that an eccentric circle is drawn on the upper surface.
Fourteen cam rotators 14a are fitted. When the other end of the sliding bar 14 is connected to the element 17 and the distance from the center of the cam rotator 14a running in the cam groove 12 becomes longer, the sliding bar 14 is pushed and the support member 18 is connected to the air suction nozzle 6. The nozzle clamp 13 is gradually oriented vertically, and the cam rotator 14a gradually returns to the horizontal direction as it approaches the center. Each support member
By adjusting the eccentric circular shape of the cam groove 12, the lengthwise state can be maintained over a plurality of work stations. The vertical sliding of the air suction nozzle 6 in the vertical state of the support member 18 and the rotation and opening and closing of the nozzle clamp 13 are performed by well-known power means provided separately.

As shown in (a), at the position of the work station A, the upper and lower ends of the packaging bag 1 successively made and conveyed by the clamp claws 3a and 3b are held in a suspended state. A plurality of work stations B, C,... I are suspended and held by the intermittent rotation of the circular table 2.
After making a full circle while stopping at the position in order, at the stage where the circuit has made a full circle, it is successively dropped onto a conveyor (not shown) provided with one end below the circular table 2 and carried out. At the work station B, as shown in FIG. 2 (b), both sides of the packaging bag 1 are suctioned by the suction pipes 4a and 4b to expand the packaging bag 1, and
As shown in FIG. 2C, the contents N are charged and filled by the filling machine 5 at the position of the work station C. The filling of the contents N may be performed over a plurality of adjacent work stations.

As shown in FIG. 7, the air suction nozzles 6 facing each other are vertically oriented and descend into the packaging bag 1 through the opening 1a, and the clamps 3a and 3b are moved outwardly so that the opening 1a is brought into tension. At the same time, the nozzle clamp 13 is closed, and the sponge-like flexible holding bars 7a, 7b open the opening 1a from both sides.
To close the gap between the opening 1a of the packaging bag 1 and the air suction nozzle 6, and suck the air in the packaging bag 1 to create a vacuum. Numerals 19a and 19b denote holding members which flexibly sandwich the side surface of the contents N filling portion of the packaging bag 1 to promote air suction and prevent deformation of the packaging bag 1 such as bending. The air suction nozzle 6 intermittently rotates with the circular table 2 while straddling a plurality of preset work stations and continuously sucks air in the packaging bag 1 to completely and surely evacuate the packaging bag 1. .

する熱シールはさらに第三次を行うこともある。Next, the packaging bag 1 reaches the work station F while the air suction nozzle 6 is inserted, and performs the first heat seal 8c with the narrow heat seal bars 8a and 8b. At this time, as shown in FIGS. 6 and 7, the opening 1a and the air suction nozzle 6 are sandwiched and held by the sponge-like flexible holding bars 7a and 7b, and the tip of the air suction nozzle 6 is held down by the holding bar 7.
The nozzle 6 is pulled up so as to stay at an intermediate position between the air suction nozzles a and 7b, the lower end of the air suction nozzle 6 is closed by the contact surface of the opening 1a, and the opening is formed immediately below the holding bars 7a and 7b. 1a is closed by heat sealing 8c. That is, when the air suction nozzle 6 is pulled up to a distant position on the opening to perform the heat seal 8c, the external air enters the packaging bag 1 for a short time until the opening 1a is closed again by the pressing bar. Therefore, the air suction nozzle 6 is pulled up so that the tip of the air suction nozzle 6 stays at an intermediate position in the holding bars 7a, 7b, and the opening 1a is held in the holding bars 7a, 7b.
Is closed by the return push of the lower half, and the opening 1a is closed by heat sealing. Thus, the inflow of the external air including the return of the suction air into the packaging bag 1 during the heat sealing 8c is reliably prevented. The packaging bag 1 in which the opening 1a is heat-sealed and closed releases the holding press by opening the holding bars 7a and 7b, and moves the air suction nozzle 6 upward through the opening 1a and pulls out to reach the work station G position.
As shown in (a), the second wide heat seal 9c is formed by the wide heat seal bars 9a and 9b to more securely close the opening 1a. The heat seal for closing the opening 1a may further perform a third order.

にエアーを吸引されることとなる。Since the air suction nozzles 6 are provided in the same number as the number of work stations, all the packaging bags 1 suspended and held by the clamp claws 3a and 3b and filled with the contents N are supplied to the air suction nozzles 6 facing each other. As a result, air is sucked without a waiting blank.

ととなる。When it is desired to further lengthen or shorten the air suction time in the bag depending on the size of the packaging bag 1 or the filling amount of the contents N, the disc 11 having the eccentric shape of the cam groove 12 is replaced and mounted. It is. The duration of the air suction nozzle 6 entering the packaging bag 1, that is, the length of the range between the work stations depending on the vertical state of the air suction nozzle is lengthened and shortened, and the air in the packaging bag 1 is reliably sucked without excess. Will be removed.

よい熱シールを形成し得るという効果を生ずる。The air suction nozzle, which has finished sucking the air in the packaging bag, is pulled up so as to stay at a position between the sponge-like flexible press bars whose tips are closed and closed, and the press bar is provided below the tip of the nozzle. Is closed by the pressing contact surface of the opening by heat sealing the opening just below the holding bar, so that the external air generated by pulling up and separating the air suction nozzle flows into the packaging bag. In addition, there is an effect that the return inflow of the suction air can be reliably prevented. Since the end of the air suction nozzle is raised to the position between the holding bars and the opening is closed with a heat seal, the effect that a good-looking heat seal can be formed without providing a hole for air suction on the side of the bag. Occurs.
