Description

  The present invention collects containers and packaging, foods, and articles from various kinds of garbage including food waste discarded from convenience stores, supermarkets, food manufacturing factories, etc., respectively, into waste plastic resources, livestock feed, or agricultural organic fertilizers. Recyclable technology.

Traditionally, foods such as lunch boxes, rice balls, noodles, prepared dishes, milk, bread, etc., sold at convenience stores and supermarkets, are discarded after a predetermined time to ensure freshness, and are collected by a dust collector. Incinerated at the landfill.
In addition, in food manufacturing factories that manufacture foods for bakery factories and convenience stores, unnecessary foodstuffs, unsold foods, and the like that are generated during manufacturing are discarded.
However, these food wastes are fresh and nutritious from the viewpoint of resources for livestock feed and agricultural organic fertilizers, and it is a valuable resource to incinerate them without using them effectively. Will be wasted.
Therefore, various proposals for effectively using these food wastes have been made. In any case, first, it is necessary to separate the food waste into food itself and containers and packaging.

The most common conventional technology for separating food waste into food itself and containers and packaging is subdivided by crushing food waste together with food and containers and subdividing them into pieces, followed by screening and specific gravity sorting. Containers and packaging debris are collected from the food body.
However, if food waste is crushed together with the container and packaging, it is inevitable that the plastic pieces constituting the container and packaging will be mixed into the food body, so that it cannot be used for livestock feed for the consumption of livestock such as pigs. .

Along with this, several techniques for separating food waste into food and containers and packaging without crushing have been proposed.
For example, in “a food waste separation method and apparatus for packed food” described in Patent Document 1 below, garbage and plastic containers are pressed by pressing a rotating flat blade, a hot wire, and a heated rotating roll against the packed food. Or it is separated into packaging.

  In addition, in the “Food Food and its Packaging Separation Device” described in Patent Document 2 below, the food and the package are separated from each other by pressing a rotary blade against the food sandwiched by the conveyor belt. Yes.

  Furthermore, in the “method for breaking bag of plastic garbage bag” described in Patent Document 3 below, the plastic bag is broken by irradiating the garbage bag containing the garbage taken from the home with a laser beam. In addition, the garbage contained in it can be easily removed.

JP 2001-62438 A JP 2002-1290 A JP 2002-28520 A

However, since the techniques described in Patent Document 1 and Patent Document 2 all press rotating blades, heat rays, heated rotating rolls, and the like against the outer surface of food, the shape of food waste to be processed Depending on the situation, the rotary blade or the like does not come into contact with the outer surface of the food, and there is a possibility that the container packaging cannot be cut, and the food main body and the container packaging cannot be reliably separated.
In addition, the mechanism for moving the rotary blade or the like along the outer surface of the food waste is complicated, and the equipment cost is increased.

Moreover, since the technique described in the said patent document 3 uses a laser beam, it cannot irradiate a laser beam to the back side of the food waste to process, and can isolate | separate a food main body and a container packaging. It becomes difficult.
Further, the laser beam irradiation apparatus is expensive, and not only the equipment cost increases, but also maintenance cannot be easily performed.

Furthermore, in recent years, many items such as cosmetics sold at convenience stores and supermarkets are packaged in packages made of polymer materials.
However, when these items are disposed of as garbage without being used, there has been no method for efficiently separating the packages from these items. Not only was it impossible to reuse resources, but it also led to increased air pollution and carbon dioxide emissions.

  Therefore, the object of the present invention is to solve the above-mentioned problems of the prior art, and can be widely applied to various forms and shapes of article garbage including food waste, and reliably separate containers and packaging from these article garbage. It is another object of the present invention to provide a container / packaging separation apparatus that can be carried out easily and that can be easily maintained with low equipment costs.

The means described in claim 1 for solving the above problem is as follows.
A container / packaging separating device for separating the container / package from an article waste in which the article is wrapped by a container / package manufactured from a polymer material,
High-temperature fluid ejecting means for ejecting a jet of high-temperature fluid having a temperature higher than the melting point of at least the polymer material toward the container and packaging;
And a container packaging fusing mechanism for fusing the container packaging by relatively moving the outer surface of the container packaging and the high-temperature fluid ejecting means.

That is, the container / packaging separation device of the present invention is a container / packaging of various article waste including food waste discarded from a convenience store, a supermarket, a food manufacturing factory, etc., a film or thin plate made of a polymer material, or a polymer material. It is made of a paper material or the like that is laminated or impregnated and can be easily melted by a jet of high-temperature fluid higher than its melting point.
For example, the melting point of polypropylene (PP) generally used as a material for packaging containers of articles is about 110 ° C. to 165 ° C., the melting point of polyethylene (PE) is about 110 ° C., and polyethylene terephthalate (PET) Has a melting point of about 260 ° C.
Therefore, since the container packaging can be blown by injecting a jet of a high-temperature fluid having a temperature higher than the melting point of these materials toward the container packaging, it is easy to separate the container packaging from various article wastes. Can be done.
The high-temperature fluid that is sprayed toward the container and the packaging can increase the pressure and also the fusing efficiency and the fusing accuracy of the container and the packaging by spraying from the injection port having an extremely small inner diameter.
In the case of food waste, since the food itself contains a large amount of water, the food itself does not easily ignite.
Further, since the high-temperature fluid sprayed toward the article garbage can freely fluctuate or be deformed, the complicated shape of the article garbage can be easily followed to be surely fused.
In addition, unlike a rotating blade which is a solid object, the container and packaging are melted using a fluid, and therefore it is not necessary to keep the distance between the article and the container packaging constant.
Further, since expensive and complicated equipment such as a laser beam oscillator is not required, it can be made inexpensive and simple, and its maintenance is easy.
Separation of the container and packaging from the food can be performed by natural dropping of the food after the container and packaging are melted, manual work by an operator, or using a machine.
In addition, containers and packaging made of polymer materials can be used for high-temperature, high-pressure, high-speed fluid jets, such as paper materials impregnated with polymer materials, or paper materials laminated or lined with films of polymer materials. Includes materials that can be melted or cut.

The means described in claim 2 is characterized in that the temperature of the high-temperature fluid in the container / packaging separation apparatus described in claim 1 is lower than the ignition point of the polymer material.
That is, the ignition points of the container and packaging material described above are about 440 ° C. for polypropylene (PP), about 350 ° C. for polyethylene (PE), and about 510 ° C. for polyethylene terephthalate (PET).
Therefore, by spraying a high-temperature fluid having a temperature lower than these ignition points toward the container and packaging, the container and packaging can be melted while preventing the container and packaging from firing.

The high-temperature fluid injected toward the container and packaging can be a combustion gas obtained by burning a combustible gas.
Specifically, for example, a high-temperature combustion gas obtained by burning propane gas itself or a flame itself can be used.
In addition, a high-temperature fluid having a predetermined temperature can be obtained by mixing the atmosphere with a high-temperature combustion gas obtained from a high-temperature combustion gas supply source such as a burner or a boiler.
The high-temperature fluid obtained in this way can be pressurized by a compressor or a pump, and can be injected from a small-diameter nozzle toward a container package.

Moreover, the high-temperature fluid injected toward the container and packaging can be heated carbon dioxide gas.
That is, when a container package is blown using a high-temperature, high-pressure jet of carbon dioxide (such as carbon dioxide gas) heated to a temperature higher than the ignition point of the material of the container package, Because it is covered with carbon dioxide, it will be extinguished immediately.
An inert gas can be used instead of carbon dioxide.

Furthermore, the high-temperature fluid sprayed toward the container and packaging can be steam.
That is, when the container packaging is melted using steam having a temperature higher than the ignition point of the material of the container packaging, even if the container packaging ignites, the surroundings are covered with water vapor, and Since water is produced by contact with the water, the fire is immediately extinguished.

In addition, the container and packaging separation device according to claim 1 or 2 can further include a fire extinguishing mechanism that supplies a fire extinguishing fluid toward a portion of the container and packaging that is melted by the high-temperature fluid. The fire extinguishing mechanism can spray water on a portion of the container package that has been melted by a high-temperature fluid, or spray water in a mist form.
Alternatively, the surface of the container package wrapped with the high-temperature fluid wets the surface of the table that slides on it or the roller that rolls on it with water, and the surface wetted with water is heated by the high-temperature fluid of the container package. It can also be set as the structure which extinguishes fire by making the melted part contact.
Furthermore, a fire-extinguishing gas, for example, carbon dioxide gas such as carbon dioxide, an inert gas, or the like can be injected into a portion of the container package that is melted by a high-temperature fluid.
In addition, water, carbon dioxide gas, or the like can be continuously sprayed toward the container and packaging, or can be configured to inject only when the container and packaging are ignited by an optical monitoring device, for example.
Therefore, even if the container / package is ignited when the container / package of the article waste is melted by the high-temperature fluid, it can be extinguished immediately.

The container packaging fusing mechanism is:
Suspension means for rotating around the vertical axis in a state where the article waste is suspended;
Contact / separation means for contacting / separating the high-temperature fluid ejecting means with respect to the outer surface of the rotating article waste.
That is, when the bottom of the container packaging of the suspended article garbage is melted, the article wrapped in the container packaging naturally falls, so that the food from the article garbage can be easily collected.
Further, by using the high temperature fluid contacting / separating means, the high temperature fluid can be immediately separated from the container packaging when the melting of the container packaging is completed, and therefore the possibility that the container packaging will ignite can be minimized. .
In addition, instead of fusing the container packaging over the entire circumference of the garbage and separating the container packaging into two parts, the container packaging is integrated by preventing a part of the container packaging in the circumferential direction from being fused. Can be recovered.

The container packaging fusing mechanism is:
A rotating table that rotates around a vertical axis in a state where the article waste is placed;
Contacting / separating means for contacting / separating the high-temperature fluid ejecting means to / from the outer surface of the article garbage rotating on the rotary table.
As a result, it is possible to easily melt and separate the container packaging from the foods that cannot be hung and those that are damaged when dropped.

The container packaging fusing mechanism is:
The article waste is conveyed forward while sliding on the upper surface thereof, and a supporting means in which a groove extending in the left-right direction is recessed in the upper surface;
Moving means for moving the high-temperature fluid ejecting means in the left-right direction inside the groove;
Can have.
That is, the bottom of the container package is melted and cut by the high-temperature fluid by moving the high-temperature fluid ejecting means in the left-right direction in synchronization with the article waste moving forward while sliding on the upper surface of the support means. Therefore, the container and packaging can be easily separated from the article waste.
Also, by wetting the upper surface of the support means with water in front of the groove, the melted portion of the container package can be wetted with water to prevent ignition or extinguish.

The container packaging fusing mechanism is:
A pair of rotating bodies that rotate in the same direction around axes that extend horizontally and parallel to each other, and on which the article waste can be placed;
Contacting / separating means disposed between the pair of rotating bodies for contacting and separating the high-temperature fluid ejecting means with respect to an outer surface of the article waste that is placed and rotating on the pair of rotating bodies;
Can have.
That is, by bringing a high-temperature fluid into contact with article garbage rotating on a pair of rotating bodies, the container package of the article garbage can be melted over the entire circumference, so that the container package can be easily separated from the article garbage. Can be done.
At this time, the surface of the rotating body on the rear side in the rotation direction with respect to the high-temperature fluid is wetted with water, so that the melted portion of the container and packaging can be wetted with water to prevent ignition or extinguish.

The container packaging fusing mechanism is:
A support member comprising a pair of opposing portions that oppose each other so as to receive the article waste therebetween and support the high-temperature fluid ejecting means;
A support member driving means for reciprocating the support member between an advanced position where the high temperature fluid melts the container package and a retracted position where the high temperature fluid is separated from the container package;
Can have.
That is, in the case of garbage such as rice balls and flat lunch boxes, etc., which are relatively thin, by reciprocating a support member having a pair of upper and lower opposed parts and receiving such article garbage in the meantime, The upper and lower side surfaces of the container package of the article waste can be blown at a time by the high-temperature fluid ejected from the high-temperature fluid ejecting means provided in the pair of upper and lower opposing portions.
At this time, since the high-temperature fluid contacts not only the upper and lower surfaces of the container package, but also the vertical wall surface of the container package, the container package is melted over the entire circumference of the article garbage, and the container package is easily separated from the article garbage. Can do.

In this case, the container packaging fusing mechanism is
A first support member for reciprocating vertically and fusing the left and right side surfaces of the container packaging;
And a second support member for reciprocating in the left-right direction and fusing both the upper and lower side surfaces of the container package.
In other words, in the case of bowl-shaped article waste such as udon or chilled Chinese soba noodles, the left and right side surfaces of the container package are melted by the first support member that reciprocates in the vertical direction and reciprocates in the horizontal direction. The upper and lower side surfaces of the container package can be fused by the moving second support member.
At this time, since the high-temperature fluid is in contact with the inclined left and right sides of the bowl-shaped container packaging, the container packaging is blown over the entire circumference even when the container packaging is bowl-shaped garbage. In addition, it is possible to reliably separate the container and packaging from the garbage.

Further, the high temperature fluid ejecting means includes
A first set of nozzles for injecting the high-temperature fluid, which are respectively provided on the front end sides of a pair of opposed portions of the support member and face each other;
A second set of nozzles for injecting the high-temperature fluid, which are provided on the base end sides of the pair of opposing portions of the support member and face each other.
That is, by providing a plurality of high-temperature fluid ejecting means on the mutually opposing portions of the support member, the high-temperature fluid can be brought into contact with the side surface of the container packaging a plurality of times with one reciprocation of the support member. It is possible to reliably melt the container and packaging of garbage.

In addition, the first set of nozzles injects the flow of the high-temperature fluid inclined toward the proximal end side of the support member, and the second set of nozzles inclines toward the distal end side of the support member. A flow of hot fluid can be injected.
Accordingly, for example, when the support member reciprocates in the vertical direction to melt the left and right side surfaces of the container package, the upper surface of the container package is melted by the first set of nozzles, and the container package is sealed by the second set of nozzles. Since the lower surface can be melted, the container and packaging can be melted more reliably.

The means described in claim 15 for solving the above problem is as follows:
A container / packaging separating device for separating the container / package from an article waste in which the article is wrapped by a container / package manufactured from a polymer material,
A body portion biased toward the article waste;
A roller that rolls on the outer surface of the article litter and is rotatably supported by the body portion;
High-temperature fluid ejecting means supported by the main body portion for ejecting a jet of high-temperature fluid having a temperature higher than at least the melting point of the polymer material toward the container package;
And a fire extinguishing mechanism supported by the main body for supplying a fire extinguishing fluid toward a portion of the container package that is melted by the high temperature fluid.

That is, in the container / packaging separating apparatus according to claim 15, the roller can be brought into contact with the outer surface of the article garbage by urging the main body portion toward the article garbage. And the high temperature fluid ejecting means can always be kept at an appropriate value.
Moreover, since the fire extinguishing mechanism is provided in the main body portion, it is possible to reliably prevent the portion melted by the high-temperature fluid in the container and packaging of the garbage from being ignited.
Since the main body portion, the roller, the high-temperature fluid ejecting means and the fire extinguishing mechanism are integrated together, the structure is extremely simple and the maintenance can be easily performed.

According to the present invention, the present invention can be widely applied to various types and shapes of article garbage, and the container and packaging can be reliably separated from the article garbage. Furthermore, the equipment cost is low and maintenance is easily performed. It is possible to provide a container and packaging separation apparatus that can perform the above-described process.
This makes it possible to reliably separate containers and packaging from various goods including food waste discarded from convenience stores, supermarkets, food manufacturing plants, etc. The main body can be collected and recycled into organic livestock fertilizer or nutrient-rich agricultural fertilizer that has high nutritional value and is not contaminated with plastic pieces.
Further, since the container and packaging can be collected without crushing, the collected container and packaging can be effectively used as a waste plastic resource or a resource for recycled paper.

Hereinafter, with reference to FIG. 1 thru | or FIG. 15, each embodiment of the container packaging separation apparatus which concerns on this invention is described in detail.
In the following description, the same reference numerals are used for the same parts, and redundant descriptions are omitted, and the direction in which food waste as an example of article waste is conveyed is the front-rear direction, and the vertical direction is the up-down direction. The direction that is perpendicular and horizontal to both directions is called the left-right direction.

First Embodiment First, a container / packaging separation apparatus according to a first embodiment will be described with reference to FIGS. 1 to 3.

The container / packaging separating apparatus 100 according to the first embodiment separates a container / packaging 1a from a food waste 1 in which a large number of foods discarded from a convenience store, a supermarket, a food manufacturing factory, etc. are stored in a container / packaging 1a such as a plastic bag. Is to do.
The food waste 1 is suspended by a guide rail 2 that extends horizontally in the conveying direction (arrow A), a roller 3 that rolls on the guide rail 2, and a suspension member 4 that hangs down from the roller 3. It is conveyed in the state where
When the roller 3 stops at a predetermined position on the guide rail 2, the spur gear 7 that is rotationally driven by the motor 6 meshes with the spur gear 5 that is fixed to the upper end of the suspension member 4.
Then, the food waste 1 is rotationally driven by the motor 6 and rotates around the vertical axis as indicated by the arrow B.

A nozzle 9 for injecting the high-temperature fluid 8 toward the container package 1 a of the food waste 1 is provided on the linear guide 10 obliquely below the food waste 1.
The linear guide 10 moves the nozzle 9 toward and away from the food waste 1 by rotating the motor 11 forward and backward, and its operation is controlled by the control device 12.

In addition, the high temperature fluid 8 injected toward the container packaging 1a is made of, for example, a polymer material constituting at least the container packaging 1a by mixing the atmosphere with high temperature combustion gas obtained by burning propane gas. A gas adjusted to a temperature higher than the melting point can be pressurized by a high-pressure pump (not shown) and supplied via a pipe (not shown).
The high temperature fluid 8 can also be heated carbon dioxide or water vapor.

  Further, as shown in FIG. 2, the hot fluid in the container package 1 a of the food waste 1 is located behind the nozzle 9 for injecting the hot fluid 8 in the direction in which the food waste 1 rotates (arrow B). Nozzle 13 is provided for spraying water in a mist shape toward the part melted by 8.

  When the container package 1a of the food waste 1 is melted by the high-temperature fluid 8, the control device 12 operates the motor 6 to rotate the food waste 1 about the vertical axis, and the control device 12 operates the motor 11. Thus, the nozzle 9 is advanced so that the high-temperature fluid 8 comes into contact with the container package 1a of the food waste 1, and at the same time, the control device 12 operates the nozzle 13 to spray the mist-like water 14.

At this time, the control device 12 does not melt the container packaging 1a of the food waste 1 over the entire circumference, but retracts the nozzle 9 of the high-temperature fluid 8 so as not to melt a portion 1b in the circumferential direction.
Thereby, as shown in FIG. 3, the container packaging 1a of the food waste 1 is connected in the circumferential part 1b and is not separated into two parts.

That is, the container / packaging separating apparatus 100 according to the first embodiment melts the container / package 1a of the food waste 1 conveyed in a suspended state by jetting the high-temperature fluid 8, and thus is accommodated in the container / package 1a. The food S that has been used can be dropped naturally, and the container packaging 1a of the food waste 1 and the food S can be separated very easily.
Moreover, since the mist-like water 14 is sprayed from the nozzle 13 to the part melted by the high-temperature fluid 8 in the container package 1a, the container package 1a can be prevented from being ignited or the ignited container package 1a can be extinguished. In addition, the amount of water adhering to the food S can be minimized.
Furthermore, although the outer surface of the food waste 1 has irregularities, the high temperature fluid 8 can be freely fluctuated or deformed. Therefore, by appropriately setting the ejection length of the high temperature fluid 8 ejected from the nozzle 9, the container packaging can be performed. 1a can be surely fused.
In addition, the position of the outer surface of the food waste 1 is measured by an optical sensor, and the control device 12 controls the advance / retreat amount of the linear guide 10 based on the measurement result, so that the high-temperature fluid 8 is surely provided on the surface of the container package 1a. It can also be made to contact.

2nd Embodiment Next, with reference to FIG. 4 and FIG. 5, the container packaging separation apparatus of 2nd Embodiment is demonstrated.
