Description

Automatic binding equipment and its method for food packing bag}

The present invention relates to an automatic food packaging bag binding device and method, and more specifically, to a device and method for sequentially moving a plastic film packaging bag containing contents and having an open opening portion and tying the opening portion of the packaging bag. will be.

Unless otherwise indicated herein, the material described in this section is not prior art to the claims of this application, and is not admitted to be prior art by inclusion in this section.

In general, food packaging bags used for food packaging are inexpensive, do not deteriorate, have excellent hygienic properties, and are flexible and easy to seal, so plastic bags using plastic films such as vinyl are widely used. In particular, the plastic bag is mainly used to package fermented foods such as kimchi, and even if the volume of the contents increases and expands due to gases generated during the fermentation process of the packaged fermented food, it can respond to a certain extent due to its flexible characteristics. There was an advantage.

However, the plastic bag cannot be sealed by itself, and a separate means for sealing the opening is required. In other words, a packaging bag made of plastic film has a configuration in which the contents are introduced inside through the opening portion and then sealed packaging is completed by binding the opening portion, but at this time, a separate binding means was needed to bind the opening portion.

The binding means at the opening part of the plastic bag as described above must be tightly bound to prevent the contents from leaking, especially for fermented foods such as kimchi or foods containing liquid such as raw oysters and salted seafood. To this end, heat compression method, Binding strings and clips with built-in wire were being used.

Prior art related to binding the opening portion of the packaging bag includes “Kimchi packaging method” in Publication Patent Publication No. 10-2018-0120331 (published on November 6, 2018), which involves cutting dried kimchi into a cylindrical shape and packaging it into a pouch. It describes a method of packaging in a type film bag or tray type container. However, this technology has a structure in which packaging is completed by inserting kimchi into a film bag with an open top, then fusion and cutting both ends of the open packaging material. Although the above prior art sealing is achieved by heat-sealing the opening of the film bag, it has the problem of not being able to respond significantly to changes in the volume of contents, such as gases, generated by fermented foods such as kimchi.

In particular, when the opening part is sealed by heat fusion, the internal volume expands due to the fermentation product gas, and the expansion pressure applied to the sealing part is transmitted directly to the fused part, causing the package to burst or the contents to leak through the opening part. problems could occur.

As a prior art to prevent the above problems, the "container for packaging fermented food" of Registration Patent Publication No. 10-1861085 (announced on June 25, 2018) is a gas that can emit carbon dioxide gas generated from fermented food. It describes a packaging container that forms an exhaust hole and includes a membrane filter that allows gas to pass through the gas discharge hole and blocks liquid.

However, the packaging container as described above is capable of discharging the gas generated during the fermentation process to a certain extent, but is configured to discharge only the gas using the membrane filter, so the amount of packaged contents is large, so the gas generated is vented through the membrane filter. If the capacity is exceeded, there is still a problem that the contents may leak or the packaging bag may swell and burst, making it unusable for packaging large quantities of food.

Public Patent Publication No. 10-2018-0120331 (published on November 6, 2018) Registered Patent Publication No. 10-1861085 (announced on June 25, 2018)

The present invention was devised to solve the problems of the prior art described above. In the technology for packaging food using a food packaging bag made of plastic film, the food is packaged by firmly binding the opening portion of the packaging bag in two stages. The primary purpose is to prevent damage and at the same time prevent leakage of contents, and also to respond to volume changes due to gases generated during the fermentation process over time after packaging of foods, including fermented foods. The secondary purpose is to package food in bulk units, and at the same time, when packaging food using plastic film bags, it is possible to package food through an automatic binding device that sequentially processes multiple packaging bags containing food.
