Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a device for removing bubbles in a flanged container when the container is filled with liquid and sealed with a film.

Conventionally, it has been known to remove bubbles that occur when a container is filled with egg tofu, pudding, or other liquid by passing the top surface of the container through a foam removal roller. In some cases, bubbles remain on the flange, and these bubbles enter the container when the tape-like film is attached to the flanged container, degrading the quality or causing defects in the fusion sealing of the film to the flange. .

The present invention is an attempt to improve such defects with an extremely simple configuration.The present invention is designed to improve such defects with an extremely simple configuration.The upper part of the conveyance device is equipped with a container support member that supports the flange of the container, and a film guide is arranged sequentially in the conveyance direction. The gist is that a presser frame bent into a mountain shape and an iron for heat-sealing the film to the container flange are provided, and an air blowing nozzle is installed diagonally toward the opening of the container in the film guide portion at the rear of the film guide. It is something to do.

An embodiment of the present invention will be described with reference to the drawings. A conveying device 2 consisting of a pair of chains 1, 1 can fit a flanged container A onto its upper surface, and container supporting members 3 supporting flanges B are attached at regular intervals. It is configured to sequentially and continuously transfer a flanged container A filled with liquid while being fitted and supported by a container support member 3.

Above the conveying device 2, there is a film guide 5 that guides the strip film C in the traveling direction of the conveying device 2 via a guide roller 4, and a film guide 5 that is swingably suspended from the guide roller 4 and guides the strip film C through the guide roller 4. A presser frame 6 bent forward into a substantially mountain shape is attached to the upper surface of the flanged container A, and the attached film C is moved up and down in synchronization with the conveying device 2 at the rear of the holding frame 6 to be attached to the flange B. A film adhesion device 8 consisting of an iron 7 for welding the film to A oriented air blowing nozzle 9 is installed obliquely through a mounting frame 10.

Since the embodiment of the present invention is constructed as described above, when the conveying device 2 is driven and the flanged container A fitted and supported by the container support member 3 is filled with liquid such as egg tofu or pudding and transferred. , the container A is sequentially transferred below the film guide 5 of the film adhesion device 8 with the bubbles rising above the flange surface, and the strip-shaped film C guided by the film guide 5 is pressed against the flange by the presser frame 6. Immediately before the film is deposited on film B, clean compressed air is injected from the air blowing nozzle 9 to eliminate bubbles on the upper part of the liquid, and at the same time, the remaining bubbles are removed from both sides by the refracted jet of air to both sides by the film C and the holding frame 6. Then, the film C is heat-sealed to the flange B using an iron 7 to seal the container A, and the film is removed by cutting between each film using a cutting device (not shown).

In the above embodiment, the conveying device 2 is composed of a pair of chains, but it is not limited to this. For example, the belt is provided with a hole into which a flanged container fits, and the upper peripheral edge of the hole is provided with a hole. It is also possible to provide a container support 3.

The present invention heat-seals a film guide sequentially in the transport direction on the top of a transport device equipped with a container support member that supports the flange of the container, a presser frame bent into a substantially mountain shape toward the front, and a film to the container flange. In addition to providing an iron, an air blowing nozzle was installed obliquely toward the opening of the container in the film guide section at the rear of the film guide, so that clean compressed air sprayed from the nozzle was applied to the flange from the diagonal rear of the container just before the film was applied. At the same time as removing the bubbles that are rising above the surface, the remaining bubbles are removed by changing the direction of the compressed air jet to both sides of the container using the film that is to be applied. Foam can be smoothly and reliably removed from the container and flange.

Therefore, it has excellent features and practicality in that it can prevent the conventional defects of quality deterioration due to bubbles remaining in the container and poor film fusion due to bubbles adhering to the flange, thereby improving work efficiency.
