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.

Face to the station position sequentially,
After filling the contents and bleeding air, in an intermittent rotary type filling and packaging machine in which the opening is closed by a number of heat seals, the number of work stations is intermittently rotated together with the circular table and one or more. This problem is solved by evacuating the air inside the packaging bag after filling the contents with an air suction nozzle that is configured to continue sucking the air inside the packaging bag across the work stations. I tried to solve it.

確実に真空にする。[0010] The packaging bag 1 in which the contents N have been filled reaches the work station D while being opened, and there is shown in FIG.
The air suction nozzles 6 facing each other are vertically oriented and descend into the bag 1 through the opening 1a as shown in FIG.
The opening 1a is brought into tight contact with each other by outward movement, and at the same time, the nozzle clamp 13 is closed and the opening 1a is pressed and closed from both sides by the flexible holding bars 7a and 7b, and the inner surface of the packaging bag 1 is closed. The air in the bag 1 is sucked and vacuumed by closing the gap between the air bag and the air suction nozzle 6. Reference numerals 19a and 19b denote holding members which flexibly press 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. .

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 holding bars 7a and 7b, and the tip of the air suction nozzle 6 is positioned between the holding bars 7a and 7b. And heat seal 8c just below the holding bars 7a, 7b to open
Block 1a. That is, the primary heat seal 8c is performed while the inside of the bag 1 is kept in a vacuum state without generating a gap into which air flows. Heat seal 8c at opening 1a
The closed packaging bag 1 releases the pinching and holding by the opening of the holding bars 7a and 7b, and at the same time, pulls the air suction nozzle 6 upward from the opening 1a to reach the work station G position, where as shown in FIG. 8 (a). The second wide heat seal 9c is formed by the wide heat seal bars 9a and 9b to more reliably and firmly close the opening 1a. Note that 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.

ができるという効果を生ずる。Since the present invention is constructed as described above, packaging in an intermittent rotary type filling machine that reliably and fully bleeds air according to the filling amount of the packaging bags and contents in a small-scale facility. There is an effect that a bag vacuum method and apparatus can be provided.

を順に吸引することができるという効果を生ずる。Since only the air in the packaging bag is sucked, the equipment such as the vacuum pump can be miniaturized, the time required for vacuum can be remarkably shortened, and the air suction nozzle is frequently rotated by intermittent rotation. Since the same number of work stations are provided, the air in all the packaging bags can be sucked in order.

を施すことができるという効果を生ずる。While the opening sandwiching the air suction nozzle is pressed and closed by the holding bar, the first heat sealing is performed immediately below the holding bar to close the opening, so that the air generated at the time of the heat sealing is closed. This has the effect of preventing return inflow of water. The air suction nozzle once penetrated deeply into the packaging bag, and then the nozzle tip was raised to the space between the holding bars, so that vacuuming around the contents can be promoted and the upper part of the bag looks good and reliable. This produces the effect that heat sealing can be performed.
