(Prior Art) When packaging hot and humid items to be packaged, a seal is made by the temperature difference between the packaging film and the item to be packaged, for example, the temperature of rice immediately after cooking and the steam (steam) produced by the rice itself. Moisture that has reached saturation is condensed on the inner surface of the film including the surface. When an adhesive seal is made by hot pressing with a hot plate or the like while the dew is condensed, the seal is not perfect and the seal becomes defective, which may cause various problems. Therefore, hot and humid foods such as rice immediately after being cooked could not be sealed. Therefore, it is necessary to make a line to secure a cooling time, and there is a problem that bacteria in a sterilized state are likely to enter bacteria during the cooling and easily propagate.

(Means for Solving Problems) In order to solve the above-mentioned conventional problems, the present invention sends out a film from a roll film, continuously feeds a hot and humid object to be wrapped onto the film, and wraps and adheres the film. In a continuous automatic packaging machine for sealing, the film is warmed immediately before receiving the supply of the object to be packaged, and hot air is blown onto the film formed in the U-shaped groove to warm the film and vapor the U-shaped gas. It is characterized in that a dew condensation preventing means is provided to expel it from the groove film.

(Working) By such means, the temperature of the film itself being sent is not warmed up, so that the moisture such as steam from rice etc. does not reach saturation and condenses on the inner surface of the film. By the dew condensation prevention means of blowing warm air, an air curtain is created in the U-shaped groove, and hot air is blown out in the supply direction of the packaged object, so vapor from the packaged object is discharged from the U-shaped groove, In the process after the dew condensation preventing means, the dry air state is maintained and the sealing surface is sealed in a dry state, so that the sealing is completed.

FIG. 1 is a diagram showing one embodiment of a continuous automatic packaging machine of the present invention. In the figure, reference numeral 1 denotes a roll film obtained by winding the film 6 in a roll shape, which is supported on two support rolls 21 and is provided at the bottom of the continuous automatic packaging machine. The continuous strip-shaped long film 6 is guided to the rear end of the conveyor 9 via the tension roll 2, the feed roll 3, and the guide roll 19. The tension roll 2 is constantly urged from the position indicated by the broken line to the position indicated by the solid line in order to eliminate the slack of the film 6 between the roll film 1 and the delivery roll 3. Reference numeral 4 denotes a photoelectric tube, for example, by detecting black marks or the like provided at equal intervals on the edge of the film so that the object to be packaged 8 is positioned at a predetermined position on the film 6 (a central portion between the black marks). It is for controlling.

A support (not shown) is provided between the conveyor 9 and the lower conveyor 12, and the articles 8 to be packaged from the conveyor 9 are sent.
In this example, the object to be packaged 8 is cooked rice that is hot and humid so that steam comes out. On the conveyor 9, a certain amount has already been weighed by a weighing device, and then sent in the form of a flat rectangular parallelepiped. . A homer 7 is provided on the upstream side of the support base (not shown), and the filmer 6 sent from the lower side between the conveyor 9 and the support base (not shown) is provided by the homer 7 as shown in FIG. Both sides of the film 6 can be raised as shown in FIG. Therefore, the article 8 to be packaged thereafter is supplied onto the film 6 from the support table (not shown), is surrounded by the film 6, and is sent. The article-to-be-packaged supply portion F is provided with dew condensation preventing means 5 and 10 for warming the film 6 before and after receiving the article-to-be-packaged 8.
It is preferable that the dew condensation preventing means 5 and 10 blow out warm air, such as an electric dryer, to blow warm air to the flat film 6 or the film 6 that has started to be wrapped as shown in FIGS. 2 and 3 to warm the film. I have to. In particular, in the case as shown in FIG. 3, the dew condensation preventing means 10 that blows out warm air creates an air curtain and blows off the steam generated from the high-temperature and high-humidity object to be packaged 8. Therefore, little moisture is sent to the subsequent process side. . The dew condensation preventing means 5 and 10 are not limited to this, and may be means for contact heating at a necessary portion of the film 6, for example, a sealing portion.

Above the rear part of the supporting base (not shown), there are two rollers that seal the film 6 that has been raised by putting both ends together.
11 is provided, and the film 6 is formed into a tubular shape as shown in FIG. A pair of a lower conveyor 12 and an upper conveyor 13 is provided downstream of this, and air in the tubular film 6 is evacuated, and further downstream, a lower horizontal seal hot plate 14 and a lower horizontal seal hot plate 14 are provided. Horizontal cutter 16 on top
An upper horizontal seal heat plate 15 is provided on the upstream side and the downstream side with the sandwiched therebetween. The product sealed by the upper and lower horizontal seal hot plates 14 and 15 and sealed by the horizontal cutter 16 for each package is received by the conveyor 17.

Immediately before being sent to the hommer 7, the dew condensation preventing means 5 blows hot air, for example, to raise the temperature of the film 6, and the hommer 7, which is the article 8 to be packaged, is hot and humid cooked rice. To be supplied. Even after this, the dew condensation preventing means 10 raises the temperature of the film 6 with warm air and expels steam or the like so that dew does not particularly condense on the sealing surface. More specifically, hot air is blown to the U-shaped groove-shaped film 6 to form an air curtain, and the hot air is blown to the supply side of the article 8 to be packaged and the heat roller 11 side to package it. Vapors emitted from the object 8 are removed before reaching the position of the dew condensation preventing means 10. After passing through the dew condensation preventing means 10, the removed steam does not flow backward due to the air curtain and becomes a dry air region. In this air region, the vapor emitted from the article to be packaged 8 is very small and is absorbed by the dry air and does not cause dew condensation. It is sent to the heat roller 11 without dew condensation and is adhesively sealed in a tubular shape. Further, after the air inside has been expelled by the upper and lower conveyors 12 and 13, the front and rear of the object to be packaged 8 are adhesively sealed by the lower horizontal seal hot plate 14 and the upper horizontal seal hot plate 15, and at the same time the horizontal cutter 16
Are separated into individual packages and sent out as a product 18 to the conveyor 17.

(Effects of the Invention) As described above, according to the present invention, steam is removed up to the sealing area even in a hot and humid packaged object by warming the film with warm air by dew condensation prevention means.
The dew point can be prevented from being reached, and therefore, sealing can be performed without dew condensation, and the continuous packaging with such a continuous film, which has not been possible in the past, can be completely sealed. Further, since the defective sealing is eliminated, it can be applied to foods and the like, and the effect to be exerted is great.
