Abstract

<P>PROBLEM TO BE SOLVED: To solve problems in the prior art, that placement of a to-be-treated bag in a proper alignment and setting of cutting position for the bag are difficult, in the case of cutting a packing material by a laser beam emitted from a laser beam apparatus. <P>SOLUTION: Packages 3 of contents hermetically sealed with a packaging material are put in a tank 1 for water 2, and floated on the water. A unidirectional swirl-flow is caused in the water to allow the packages 3 to flow in the stream in order to align side by side along the periphery of the tank. The packages 3 are scooped and aligned one by one on a conveyor 5 and carried to the underside of a cutting device 7. The package 3 is cut in its upper surface with the laser beam cutter 9. The packaging material is thermally cut linearly, or in a letter X, or O, etc., by scanning a laser beam on its upper surface. <P>COPYRIGHT: (C)2003,JPO

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bag breaking device for opening a large number of airtightly packed relatively small packages. 2. Description of the Related Art Products such as foods and daily necessities are distributed in the market by sealing the product in a transparent or opaque plastic bag and printing the product name, product content and the like. Conventionally, when opening a large number of sealed bags such as foods, a person manually cuts the bag with a blade, or breaks the package containing the contents with a rotating body attached to a crusher. After bagging, a method has been used in which the packaging material is blown off by wind power or separated by utilizing the difference in specific gravity between the contents and the packaging material. However, it is time-consuming to break the bag by hand when the strength of the packaging material is high, and the load on the operator is large when the contents are deteriorated. In many cases, it is necessary to separate the packaging materials from the contents after breaking the bag.Also, when using foodstuffs as feed for the effective use of resources, it is necessary to avoid mixing the packaging materials. When used, sufficient separation was difficult. [0004] For the reasons described above, a large number of packages can be broken quickly, efficiently and safely, and the contents can be easily separated from the packaging material. The challenge was to do it. Another problem is that when the bag breaking operation is cut by a laser device, the processing objects are aligned and the cutting position is set accurately. [0005] In particular, expired or waste packages such as noodles and ready-to-eat foods are desirably reused as feed for livestock for effective use of resources. In order to reuse it for feeds, it is necessary to take a method that can minimize the incorporation of plastic in packaging materials into feeds. SUMMARY OF THE INVENTION The present invention is intended to mechanize a portion of the bag breaking operation and to avoid intermingling when separating the contents of the package and the packaging material. is there. That is, put the contents sealed with the packing material in the tank filled with water, float on the water surface and give a rotating flow of water in a certain direction,
The packages are made to flow according to the water flow so as to be arranged along the periphery of the tank, the packages are scooped up one by one on a conveyor, aligned and transported under the cutting device, and the packaging material on the upper surface of the package is laser-cut by the laser cutting device. It is made to cut. [0007] Cutting for bag breaking is performed by scanning a laser beam so that the upper surface of the packaging material is linear, X-shaped,
Cut into a circular shape. In order to perform cutting accurately, it is necessary that the packaged goods be properly lined under the laser cutter. In order to arrange and supply packages under a laser cutter, it is necessary to arrange the packages on a conveyor for conveyance in order. As a method of arranging the processed products, there is a method of arranging while applying vibration like a parts feeder, or a method of picking up and arranging by a robot. However, the method using a parts feeder is suitable for a material having high rigidity, but has a drawback that it is not possible to arrange large items and soft noodles and other packaged products. In addition, the method of arranging using a robot has a drawback that the processed product is often treated in a random direction and position, so it takes time to detect the position to determine the position to be grasped, so it is not suitable for quick work. . Therefore, in the present invention, a water tank filled with water is used as a medium for arranging the packaged goods, and the packaged goods floating on the water are floated on the water, and a water flow rotating in a certain direction is given to the water, and the packaged goods are arranged along the edge of the water tub. The packaged products are scooped up by a conveyor and transported under a laser cutter for cutting. For example, when the screw is rotated at the center of the water tank, the floating processing material floats and rotates according to the rotation direction of water. Therefore, a guide suitable for the shape of the packaged product is provided at the portion of the conveyor where the packaged product is pulled up in a line, and the guided packaged product can be continuously transported to the cutter unit if the packaged product is pulled up by the conveyor. As the laser cutter, polyethylene,
A carbon dioxide laser is suitable for cutting plastic packaging materials such as polypropylene. If the output is adjusted according to the type and thickness of the packaging material, the laser light will melt the packaging material, so there will be no fine-powder plastic fragments unlike cutting with a rotary blade. It is avoided. The package cut by the laser in this manner can be easily separated from the contents and the packaging material by a separator or a human hand in a later step. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The bag breaking device of the present invention comprises a water tank, an alignment conveyor, a conveyor for transportation, and a laser device. Using the apparatus of the present invention, the package is put into a water tank, aligned by an alignment conveyor, transported under a laser device by a transport conveyor, and cut by a laser beam to cut the contents and the packaging material in a later step. Can be separated.
In the bag breaking device according to the present invention, the shape of the water tank can be circular, polygonal, or the like. Embodiment 1 An embodiment of the present invention will be described below with reference to the drawings. 1 and 2, a water tank 1 contains water 2, and a package 3 is floating on the water. The packaged product is flowed in a rotating direction because water flows in a certain direction by the stirring blade 4 or a water flow pump. The packages arranged along the wall are conveyed to the upper part by an alignment conveyor 5 and transported by a conveyor 6.
Thereby pass below the carbon dioxide laser device 7. At this time, the upper surface of the packaging material is cut into a linear shape, a cross shape, a circular shape, or the like by scanning a laser beam according to the shape of the packaged product. The package from which the packaging material has been cut is completely separated into contents and packaging in a later step. In the present apparatus, the size of the water tank can be appropriately determined according to the size of the packaged product and the amount of bag breaking, and the tank is made of a plastic material such as vinyl chloride or FRP or a metal material such as stainless steel. In addition, a carbon dioxide laser is suitable for the laser device, and if the output irradiating is too large, the contents will be thermally affected. Therefore, it is desirable to use the minimum output that dissolves the packaging material. The type is appropriate. According to the present invention, if the packaged product can be floated on water, the bag can be broken quickly, and the packaging material can be melted and cut by laser light. As a result, there is no debris of the packaging material, so that the contents and the packaging material can be separated so as not to be mixed in the subsequent process.
