When food is packaged hygienically and continuously in a plurality of rows in various forms of packaging, a complicated method is required for charging processed food into a packaging container or injecting a plurality of rows of food. In addition, there is a problem that the shape of the processed food is not broken and damaged. Therefore, in order to prevent these problems, processed foods are filled in a film bag container and sealed, and foods are generally added sequentially by a disk system. There is a demand for automatic packaging of processed foods continuously in multiple rows.

Other conventional methods for packaging processed food include applying pressure to the bag from outside the plastic film bag in which the processed food is placed in a cylindrical packaging container with a single film, and air in the bag. Extruding methods are known. However, in this method, there is a possibility that the processed food is pressurized and deformed and damaged.

In such a method, it takes an extra time for the processed food to be cooled to a certain temperature, so that the work efficiency is reduced, and an extra device is provided, resulting in an increase in manufacturing cost. There was a problem. Moreover, the conventional packaging machine is made into a cylinder with a single film and crimped to the bottom, and after filling, the top of the bag and the bottom of the upper cylindrical container are crimped. Because there is a single film, there is a limit to the capacity, and in order to increase production, it is better than increasing the number. Increasing the number of people increases the number of people, increasing costs such as location and capacity and increasing manufacturing costs.

The present invention has been made by paying attention to a packaged food in which such a conventional processed food can be automatically packaged in a plurality of rows using two sheets of film continuously and is in a packaging state in an appropriate packaging shape. When processing processed foods of raw noodles such as tofu, deep-fried udon, noodles, ramen, etc., it can be continuously packaged in multiple rows regardless of the temperature of the processed food, and hygiene without damaging the processed food The purpose is to provide a multi-row continuous automatic packaging device for processed foods that can be continuously packaged.

Place the food, cover the roll-shaped thermoplastic film sheet with the supplied film sheet at the film roll part from the top, make holes at both ends of both films so that the upper and lower film sheets are displaced and transferred, A film guide unit that allows the two sheets to be guided with high accuracy by being transferred by the claw unit, and a heating roll that continuously fuses the side surfaces into a plurality of rows in order to form the transported film sheet into a container shape. Heat-bonding part that melts the inlet part of the film container when a certain amount of processed food is filled in the film container. It has become and a trowel unit, and to allow quantitative continuous wrapped laterally.

The accuracy of the transfer could be improved by moving the two film sheets forward without any gaps, making holes at both ends of the film, and providing pawls. The size of the hole was about 1 to 5 mm, and the hole was completed by transferring it by 5 to 10 mm as an interval.

  Of the resin films having a thickness of 20 to 100 microns, a polyolefin film is often used as the material for the film sheet, and a polypropylene film is particularly preferable. The shape of the supply portion of the cylindrical can or the injection guide used to make this film sheet into a film container so that processed food can be filled in the container is cylindrical, conical and has an opening diameter of 30 mm to 150 mm, length is 30 mm to 300 mm, and the materials are stainless steel, aluminum and resin, and the multi-row continuous wrapping device for processed foods that can supply processed food from each cylindrical part It is.

  In the present invention, the supply portion of the cylindrical can or the guide for infusion that makes the film sheet a film container and can be filled with the processed food is a bag-like or cylindrical shape that can fill the processed food with a specified amount. , Conical, elliptical and trapezoidal.

The film guide section that can guide the two thermoplastic film sheets to be conveyed is located on the outer periphery of the cylindrical can and guides the supply of the two thermoplastic film sheets to be conveyed continuously. And a cylindrical or conical conveyance guide that can form a bag-like film container that can be filled with processed food.

  A heating roll or a bag-forming thermocompression stick that fuses two side-by-side thermoplastic film sheets into a plurality of rows in a continuous manner to form a container. In order to make it into a container, it consists of two thermocompression-bonding rolls or thermocompression-bonding rods that can heat-seal the film continuously.

  The piston-type pressing unit that fills a certain amount of food into the film container is filled with a prescribed amount by injecting processed food and sandwiched between the piston-type pressing tools on both sides, and the upper part of the film container is fused. It consists of a piston-type heat fusion iron part that can be made.

  In the present invention, a film container filled with processed food is placed 2 to 20 in the transverse direction by a heating roll or a bar-like crimping section that continuously fuses the side surfaces in parallel to form the film sheet being conveyed into a container. This is a multi-row continuous wrapping device for processed foods, which can be continuously produced by carrying various shapes of packaging in a plurality of rows.

Further, the multi-row packaging apparatus for processed food according to the present invention is the width of a thermoplastic film container formed into a film container opened upward in a multi-row continuous packaging apparatus for processed food that is automatically packaged from processed food.

As described above, according to the multi-row continuous packaging apparatus for processed food according to the present invention, the film bag containing the processed food is packaged by the adhesive means in the special packaging state of the film container. After that, since it is sealed with the upper film bag, it is not necessary to cool the processed food to a certain temperature as in the conventional example, and it can be automatically packed continuously in multiple rows, so that the work efficiency is significantly improved. It can be safe from the surface.

Moreover, the processed food with which the film bag container was filled can be stably sealed in the bag. In addition, the processed food can be continuously packaged in a plurality of rows in a sanitary manner in the film bag.
Since processed foods can be packaged with two different types of films, the air permeability and sealing performance of the film bag can be ensured, and the packaging productivity can be greatly improved.
Since conventional wrapping machines are individually packaged, it is necessary to increase the speed or the number of units in order to increase the capacity. For this reason, if the speed is increased, the heating is not performed unless the heating temperature is increased. Since the temperature is raised, there are many sealing errors due to film strength.
On the other hand, in the case of multiple rows, the capacity can be increased several times by increasing the rows, so the speed can be low. Because of its low speed, the crimping temperature is low and the film strength is reasonable.

  Since the conventional packaging machine is a single product packaging, transportation and movement after packaging is a conveyor or human power and costs money, but in the device of the present invention, heating, cooling, etc. are performed in a vertical and horizontal alignment after packaging. There are no complicated equipment such as cost and conveyor, production capacity is large, and manufacturing cost is very low.
