Description

Container recycling unit

The present invention relates to a recycling apparatus for a container, and more particularly, to automate a heat-shrinkable film sealed at the outer circumference of a container to recover and recycle a glass container or a plastic container of various sizes or shapes. By cutting and separating with a laser irradiator on the line, the process of removing the heat shrinkable film can be mechanized and automated, and the economical efficiency can be secured by drastically reducing the cost of removing the heat shrinkable film from the outer periphery of the packaging container. And a recycling apparatus for a new type of container.

Containers such as packaging containers are molded of glass or synthetic resin, and the outer periphery of these packaging containers is to be printed and printed with a label, design, and a simple instruction manual indicating the contents stored in the packaging.

These packaging containers can be printed and marked directly on the outer periphery of the container, as examples, such as trademarks and various designs on heat-shrinkable films (PET film, PP film, PE film, PVC film, OPS film). In some cases, the product manual, precautions for use, safety precautions, quality markings, barcodes, etc. may be printed on the outer periphery of the packaging.

Recently, the printing of a separate heat-shrinkable film on the outer circumference of the container is more mainstream than the direct printing on the outer circumference of the packaging container.

Looking at the manufacturing process of the heat-shrinkable film printed as described above, while supplying a transparent film sheet to the printing device, after printing a trademark and instruction manuals with various patterns and colors on the surface of the film, and then adhesive on both ends of the printed film It is glued into a cylindrical roll.

Then, the roll-shaped printed film is installed in the film feeder, and the printed film is cut at regular intervals through the film feeder. Then, the cut film is inserted into the outer periphery of the packaging container, and the packaging container passes through the heater. The printed film is heat-shrinked on the outer circumference of the packaging container to be tightly sealed.

The packaging container for storing various contents is made of synthetic resin or glass, but most of the packaging container is made of synthetic resin for the convenience of use and transportation and storage of the packaging container.

The packaging containers made of synthetic resin are composed of a main body of the container, a cap that opens and closes the opening of the container, and a heat shrinkable film sealed to the outer periphery of the main body.

In general, the packaging container of synthetic resin material is formed of the same material as the body and the cap of the container, the heat-shrinkable film sealed on the outer periphery of the body is formed of a different material than the body of the container.

On the other hand, certain fields in which packaging containers cannot be made of synthetic resin materials, such as shochu bottles, beer bottles, various food and beverage bottles, medicine bottles, pesticide bottles, etc., are excellent in synthetic resins. I use it.

The glass container is sealed with a heat-shrinkable film on the outer circumference of the container, and product information such as a trademark and various instructions of the corresponding product is printed on the outer surface of the heat-shrinkable film.

Therefore, the producer recovers the empty bottles to recycle such glass containers, separates and removes the heat-shrinkable film sealed on the outer circumference of the glass container, and then washes the inside of the glass container and reloads the contents into the glass container. The container will go through a recycling process.

Recently, with increasing interest in environmental pollution, energy saving, product cost reduction, and recycling of resources, synthetic resin packaging containers that are disposed of after being used once are not recycled by separating the container body and labels, or collected and damaged. In the technical field of removing the heat-shrinkable film sealed on the outer circumference of the glass container, and then cleaning the glass container and recycling it, there is an increasing trend.

Looking at the recycling process of the used plastic packaging container,

Packaging containers made of synthetic resin such as PET bottles must first be recycled after cutting and removing the heat-shrinkable film (label) sealed at the outer periphery of the body.

Therefore, the packaging container made of synthetic resin is collected, and the worker removes the heat-shrinkable film sealed on the outer periphery of the container by hand, or the collected packaging container is shredded with a shredding device and soaked in water, and then the container body is shredded by specific gravity. It uses a method of separating the flakes and the heat shrinkable film.

Therefore, the recycling of packaging materials made of synthetic resins caused excessive labor costs by separating the heat-shrinkable film by manual labor, and the recycling cost increased.In case of recycling the packaging containers, the equipment for crushing the packaging containers is expensive and wide installation. It had the disadvantage of requiring space.

On the other hand, if you look at the recycling process of the glass packaging container used and collected,

It is to recover the glass container, break it into a certain size, wash the foreign matter, and then melt it to a temperature above the melting point and use it as a material.

As above, a device for crushing and melting a glass container is required for recycling, but this was not economical because of too much cost and process for recycling.

Recently, in order to solve such a problem, methods for removing the internal foreign substances in the glass container and using them immediately have been developed.

In other words, a technology for incineration by heating above a temperature at which a sticker can be burned by an incineration device, which is a device for removing a sticker attached to a glass container, has been developed.

However, such an incineration technique is a problem that the glass container is damaged or the shape of the glass container is deformed due to uneven thickness of the glass container due to the uneven thickness of the glass container if the heat treatment according to the temperature is incorrect. When the glass container is sufficiently preheated, there is a problem in that the productivity of the glass container is deformed, as well as the increase in processing time and the heat consumption amount are high.

Therefore, in order to solve this disadvantage, various techniques have been developed to detach the heat shrinkable film heat-shrunk sealed on the outer periphery of the glass container.

Since the heat-shrinkable film is closely adhered to the heat shrinkage on the outer periphery of the glass container, it is very difficult to detach it. As an example of the prior art, a worker cuts the shrinkage film in the longitudinal direction with a knife and peels off the glass containers recovered by wholesalers. However, the work of separating the shrink film was cumbersome and complicated, which resulted in inefficient work efficiency and the inability to automate the recycling process.

As another example of the prior art, an operator for recycling the glass container used by forming two lines of cutouts in the longitudinal direction in advance in the longitudinal direction of the glass container, and then sealing them on the outer periphery of the glass container by heat shrinkage. The film was cut along the cut line of the shrink film to separate the shrink film from the glass container. However, when sealing the shrink film in the glass container, the shrinkage line of the shrink film was damaged due to the high temperature, which resulted in a defect.

As another conventional technology, glass containers such as Korean Utility Model Registration No. 428045 have been developed.

The structure of the glass container is a glass container consisting of a glass container, a cap sealed to the upper neck of the glass container, and a heat shrinkable film sealed to the outer periphery of the glass container,

It is made by attaching a film heating tape in the longitudinal direction to the rear surface of the heat-shrinkable film sealed on the outer circumference of the glass container.

Therefore, when the glass container passes through the high frequency generator on the conveying device to recover and reuse the glass container, high heat is generated on the film heating tape by the high frequency wavelength, and the heat shrinkable film portion that contacts the melt melts the heat shrinkable film on the outer periphery of the glass container. It was to be separated.

However, when the glass container with the above structure is recovered for the reuse of the glass container and passed through the high frequency generator on the conveying device, the heat shrinkable film part in contact with the film heating tape is perfectly in accordance with the outer periphery of the glass container. It did not melt and eventually the heat shrinkable film could not be removed cleanly and completely from the outer periphery of the glass container.

Therefore, with all the conventional glass container recycling apparatus, an economical and automated method was not possible to recycle used glass containers, and even if the producer wanted to print more and more variously, the heat-shrinkable film covered on the outer periphery of the glass container. There was no proper means to remove the heat-shrinkable film from the outer periphery of the glass container, so the outer periphery of the glass container could not be printed in various and colorful ways.

Therefore, the conventional glass container recycling apparatus is mostly to crush the glass containers and melt them in the smelter to rebuild the glass containers, rather than recover the used glass containers and recycle them. It was very uneconomical.

The present invention was developed to solve the above conventional problems, the recycling apparatus of the container of the present invention,

By transporting recycled glass containers to conveyor belts on an automated line, cutting the heat-shrinkable film sealed on the outer periphery of the glass container with a laser irradiator to safely and completely separate the heat-shrinkable film from the outer periphery of the container, and to various sizes and shapes. Not only can the containers of the present invention be recycled through the container recycling apparatus of the present invention, but also the process of removing the heat-shrinkable film sealed on the outer circumference of the glass container can be mechanized and automated, and the heat-shrinkable film is removed from the glass container. The present invention provides a recycling apparatus for containers that can significantly reduce costs and ensure economic feasibility.

In order to achieve the above object, the recycling apparatus of the container of the present invention,

A device for recycling a container,

A main body;

A pair of side conveyor belts installed on one side of the main body to sequentially lay down containers for recycling;

A brush roller which is transported by the side conveyor belt and shakes off foreign substances attached to the heat-shrinkable film sealed in the container;

A laser irradiator for cutting the heat-shrinkable film sealed at the outer circumference of the container by a predetermined width while being transported by the side conveyor belt;

It consists of a plurality of air spraying devices and brush rollers that open and shake the openings of the heat-shrinkable film cut by the laser irradiator to separate the heat-shrinkable film from the container.

As described above, according to the recycling apparatus of the container of the present invention,

By cutting the heat-shrinkable film sealed on the outer circumference of the container with a laser irradiator through the container recycling device of the glass or synthetic resin material by the laser irradiator to completely separate from the outer circumference of the container,

Regardless of the size or shape of the container, the container can be recycled by safely separating the heat-shrinkable film sealed on the outer periphery, and the mechanization and automation of the process of removing the heat-shrinkable film from the container can be achieved. Economics can be achieved by drastically reducing the cost of removing the film, and it is also possible to meet the national interest of recycling resources while preventing waste of resources.

In addition, even if the thickness of the heat-shrinkable film is increased by double triple sealing of various types of heat-shrinkable films on the outer circumference of the container, the heat-shrinkable film is heated by a constant width by irradiating infrared rays with a laser irradiator by the container recycling apparatus of the present invention. It can be cut and recycled to prevent waste of resources, and product producers can also reduce the production cost of products by recycling containers.

Hereinafter, a recycling apparatus for a container according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

The containers described below are heat-shrinkable films (PET film, PP film, PE film, PVC film, OPS film) sealed on the outer circumference of the container 1, and heat shrink sealed on the outer circumference of these packaging containers. The film can be completely separated through the container recycling apparatus of the present invention.

Container recycling apparatus of the present invention, as shown in Figure 1 to 10,

A main body 100;

A pair of side conveyor belts 200 which are installed at one side of the main body and sequentially lay down containers 1 to be recycled;

A brush roller 300 which is transported by the side conveyor belt and which shakes off foreign substances attached to the heat-shrinkable film sealed in the container;

A laser irradiator 400 which is transported by the side conveyor belt and cuts the heat-shrinkable film sealed at the outer circumference of the container by a predetermined width;

It consists of a plurality of air spraying device 500 and brush roller 600 to open and shake the opening of the heat-shrinkable film cut by the laser irradiator to separate the heat-shrinkable film from the container.

The main body 100 supports each of the components while fixing the components.

The side conveyor belt 200 is installed to face each other on one side of the main body 100, as shown in Figures 2 and 4, rotated by a motor and a plurality of interlocking rollers, by lying down the containers (1) to be recycled It is conveyed sequentially.

Containers (1) introduced into the side conveyor belt (200) is transported by inverting the container so that the inlet of the container (1) is located in the rear so that it is easy to remove the heat-shrinkable film and then blow it with air and shake it off with a brush. Preferably, but not limited to.

The pair of side conveyor belts 200 are transfer lines of the container 1 to protect the conveyor belts when the heat-shrinkable film of the container introduced into the main body 100 is cut by the laser irradiator 400 described later. It is preferable to install side conveyor belts 200 located on both sides of the image.

The laser irradiator 400 cuts the outer circumferential heat shrinkable film of the container transported by the side conveyor belt by a predetermined width, and the laser irradiator 400 irradiates infrared rays to the heat shrinkable film sealed at the outer circumferential edge of the container. Thus, the heat-shrinkable film sealed at the outer circumference of the container is cut by a predetermined width.

The laser irradiator 400 damages the human body or other parts of the whole system by absorbing infrared rays passing through the body of the container 1 which is transported along the side conveyor belt 200 by installing the copper plate 401 directly below. It was not allowed to.

The laser irradiator 400 heats and cuts a heat-shrinkable film attached to the outer circumference of the container 1 using an infrared laser that is invisible. The laser irradiator 400 is a gas laser among various types of lasers used for industrial purposes. Corresponding Co ₂ lasers are preferred, but are not limited thereto.

The laser irradiator 400 may use a high power laser of 100 Watt or more according to the thickness of the heat shrinkable film, and in general, since the outer circumferential shape of the container 1 is bent, the heat shrinkable film is cut by an infrared laser. In order to minimize the damage to the physical properties, the lens with the long focal length was used to give the effect of irradiating the laser beam twice and to disperse the energy.

The container 1 in which the heat-shrinkable film is cut by the laser irradiator 400 may be applied to both a glass container or a plastic container.

In the case of the glass packaging container, the heat-shrinkable film of the outer periphery may be cut by heating by a predetermined width by the laser irradiator 400, and then the glass packaging container may be washed and recycled.

In the case of the synthetic resin packaging container, the heat-shrinkable film sealed at the outer periphery of the synthetic resin material has a problem in recycling the synthetic container material and the material.

Therefore, the packaging container made of synthetic resin should remove the heat-shrinkable film sealed on the outer periphery, and then recycle the container. When the heat-shrinkable film is cut by heating the laser irradiator 400, the packaging body of the synthetic resin melts together. Even if cut, there is no problem in recycling the packaging.

Smoke generated when the laser irradiator 400 heats and cuts the outer peripheral heat-shrinkable film of the container 1 by installing an air suction device 402 operated by a compressor at a point adjacent to the laser irradiator 400. Inhaled and discharged to the outside to maintain a pleasant workplace.

The air spraying device 500 and the brush roller 600 which install the air spray nozzle 403 operated by a compressor at the back adjacent point of the laser irradiator 400 and describe the heat shrinkable film cut by the laser irradiator later. Before desorption by sintering, it was made to open first at the outer periphery of the container 1.

The air spray nozzle 403 is not an essential component of the container recycling apparatus constituting the present invention, but is a technical configuration that can be selectively installed according to the type and working conditions of the container to be recycled.

The plurality of air spraying apparatus 500 and the brush roller 600 are organically configured with each other as shown in FIGS.

The plurality of air injectors 500 are fixed on the bracket 501 directly above the transfer line of the containers 1 in which the heat-shrinkable film is cut by the laser irradiator 400, so as to be attached to the upper surface of the container by an external compressor. Infuse air intensively.

Therefore, the opening of the heat-shrinkable film cut by the laser irradiator 400 is opened by injecting a high-pressure air directly above the container 1 in which the heat-shrinkable film is cut by the air spraying device 500.

On the other hand, the brush roller 600 is installed adjacent to the air spraying device 500, these brush rollers 600 are radially installed on four shafts 601 driven by a motor.

Therefore, the plurality of brushes are opened at the same time as opening the openings of the heat-shrinkable film cut by the laser irradiator 400 by injecting a high pressure air directly from the container 1 passes by the plurality of air injectors 500. The rollers 600 remove the heat-shrinkable film from the outer circumference of the container 1 to remove it safely and completely, and then discharge it to the outside.

Meanwhile, as shown in FIGS. 2 and 4, the structure for transferring the container 1 into the recycling apparatus of the container of the present invention is a container 1 to be recycled by both side side conveyor belts 200 in front of the main body 100. ) Are laid down and transferred sequentially into the device.

9 and 10, a support 602 in which a container is placed on the lower portion of the brush roller 600 and a plurality of container transfer ports 603 are provided on the left and right sides of the main body.

The container conveying port 603, the ball bearing 605 which is supported by a spring on the inner upper end of the cylinder 604, rolling operation of the ball bearings recycled containers (1) is made, the front side conveyor belt The pushing force of 200 is to transport the vessels backward.

The recycling apparatus of the container of the present invention can be applied to all glass containers or synthetic resin containers of various sizes and shapes, and the entire system for recycling of containers can be automated and mechanized. Higher economic benefits can be achieved compared to the destruction of recycling bins and recycling them, and the recycling of discarded resources can prevent national waste.

In addition, even if the thickness of the heat-shrinkable film is increased by double triple sealing of various types of heat-shrinkable films on the outer circumference of the container, the heat-shrinkable film is heated by a constant width by irradiating infrared rays with a laser irradiator by the container recycling apparatus of the present invention. It can be cut and recycled to avoid waste of resources, and product producers can reduce the production cost of products by recycling containers.

As described above, the recycling apparatus for a container according to the present invention has been described with reference to the illustrated drawings. However, the present invention is not limited thereto by the embodiments and the drawings disclosed herein, and by those skilled in the art within the technical scope of the present invention. Of course, various modifications may be made.
