Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garbage bag removing apparatus for removing cut-out garbage bags mixed with resource garbage such as aluminum cans and glass bottles from such resource garbage in a resource garbage sorting plant or the like. .

[0002]

2. Description of the Related Art In recent years, aluminum cans, glass bottles, and the like among refuse from general households have been collected as recyclable refuse and then sorted by type at a refuse sorting plant for recycling.

[0003] By the way, such resource refuse is generally
Collected in a garbage bag made of resin film such as vinyl. Therefore, in the resource garbage sorting plant, such a garbage bag is cut open using a bag breaking device to expose the resource garbage stored therein, and then the garbage bag cut open using the garbage bag removal device is removed from the resource garbage. Must be removed.

As an example of such a garbage bag removing device,
In the "preliminary sorting device for recyclable refuse" described in JP-A-8-103726, a garbage bag conveyed over a grizzly bar formed in a saw-tooth shape is scooped up using comb teeth. Air is blown out from the inside of the comb teeth that have been turned to remove the garbage bag entangled with the comb teeth.

[0005] In a "garbage bag breaking device" described in Japanese Patent Application Laid-Open No. 8-243425, air is sucked from a distal end opening of a rotary arm formed in a cylindrical shape, so that the distal end of the rotary arm is rotated. When the rotating arm rotates to a predetermined position while adsorbing the broken garbage bag,
This time, air is blown out from the opening at the tip of the rotating arm to separate and remove the garbage bag.

[0006] In a "bag removing apparatus" described in Japanese Patent Application Laid-Open No. 9-965, air is jetted upward from below a net conveyer for transferring refuse to form an upward airflow. The garbage bags conveyed above are lifted, and the lifted garbage bags are transported and removed by hooking on hooks while being suctioned by an upper conveyor provided above the net conveyor.

Further, in the "bag removing apparatus" described in Japanese Patent Application Laid-Open No. 9-966, when recyclable refuse is put into a tapered cylindrical scissor-shaped rotary drum, it is projected inside the rotary drum. The garbage bag caught by the hook and lifted upward is blown down into the tray by air jet and removed.

[0008]

However, the "preliminary sorting apparatus for recyclable refuse" described in Japanese Patent Application Laid-Open No. H8-103726 requires continuous reversal of comb teeth for picking up refuse bags. In addition, the efficiency of removing garbage bags is low, and a large number of comb teeth must be provided. In addition, compressed air must be supplied to the inside of the comb teeth, resulting in a complicated structure and expensive equipment.

Further, the "garbage bag breaking device" described in Japanese Patent Application Laid-Open No. 8-243425 has a structure capable of sucking and removing a garbage bag only when the opening end of the rotary arm approaches the garbage bag. And the efficiency of removing garbage bags is low. In addition, since it is necessary to rotate the rotary arm and to reverse the direction of the flow of the compressed air supplied into the rotary arm, the structure is complicated and expensive equipment is required.

The "bag removing apparatus" described in Japanese Patent Application Laid-Open No. 9-965 has a structure in which a garbage bag is lifted by an ascending airflow, and the lifted garbage bag is transported and removed while being suctioned. Therefore, a compressed air supply device and a suction device are required, and the structure is complicated and expensive. Further, the refuse bags pressed on the net conveyor by the resource refuse cannot be removed, and the efficiency of removing the refuse bags is low.

[0011] Further, in the "bag removing device" described in Japanese Patent Application Laid-Open No. 9-966, not only does a garbage bag fall from the gap of a rotating drum formed in a shape of a scale,
Since the garbage bag caught on the hook provided on the rotating drum falls before reaching the tray, the efficiency of removing the garbage bag is low.

That is, all of the above-mentioned conventional garbage bag removing apparatuses are inevitably inexpensive equipment having complicated structures, and the garbage bag removing efficiency is low. Therefore, an object of the present invention is to solve the above-mentioned problems of the prior art, and to provide a refuse bag removing apparatus that has a simple structure, can reduce operating costs, and can remove refuse bags with high efficiency.

[0013]

A garbage bag removing apparatus according to the present invention for solving the above-mentioned problem is an apparatus for removing the garbage bag from resource garbage mixed with a cut garbage bag,
A plurality of pins are protruded from the endless conveyor belt wound around the plurality of winding drums on the resource litter mounting surface, and an inclined portion for transporting the resource litter obliquely upward and the resource litter are horizontally oriented. A conveyor line having a horizontal portion to be conveyed forward, a first discharge port for discharging the resource refuse dropped below the inclined portion, and a second discharge port for discharging the garbage bag dropped below the horizontal portion. A housing provided around the conveyor line and having an outlet. Then, the conveyor line receives the resource waste in the inclined portion. Preferably, the pins are composed of long pins and short pins alternately arranged with a gap.

Further, the refuse bag removing apparatus of the present invention further comprises a first auxiliary means for guiding the input resource refuse to the conveyor line. The first auxiliary means is disposed in parallel with each other with an interval capable of passing the resource waste, and is fixed such that its tip faces the tip of the long pin with a gap. Are formed in a "sawdust" shape as a whole.

The garbage bag removing device of the present invention receives a garbage bag falling along the inclined portion,
A second auxiliary means for guiding the received garbage bag to the resource garbage mounting surface of the conveyor belt can be further provided.
Here, the second auxiliary means may be a chain or a wire suspended from the inner wall surface of the housing.

Further, at the front end of the horizontal portion in the conveying direction, the conveyor belt advances along the surface of the winding drum to reverse the traveling direction of the garbage bags conveyed on the horizontal portion of the conveyor line. The apparatus may further include third auxiliary means for displacing the portion toward the resource waste mounting surface of the portion. The third auxiliary means can also press the refuse bag against the resource refuse mounting surface. The third auxiliary means may be a chain or a wire suspended from the inner wall surface of the housing. Weights can also be attached to the lower ends of these chains or wires. Further, the third auxiliary means may be an air flow forming means for forming an air flow flowing toward the resource waste mounting surface.

Further, the waste bag removing device of the present invention is a fourth auxiliary means for guiding the resource waste discharged from the horizontal portion of the conveyor line forward in the transport direction toward a third discharge port formed in the housing. Can be further provided.

The garbage bag removing apparatus according to the present invention is further provided with a fifth auxiliary for engaging the garbage bag entangled with the pin below the horizontal portion of the conveyor line and detaching the garbage bag from the pin. Means can further be provided.

That is, the waste bag removing apparatus of the present invention has an extremely simple structure in which only the first to fifth auxiliary means are fixedly installed around the conveyor line. Further, the garbage bag removing device of the present invention only needs to continuously operate only the conveyor line, and it is not necessary to continuously operate the device for removing garbage bags or using a large amount of compressed air, The operation cost can be greatly reduced as compared with the conventional apparatus. In addition, since it is a type of transporting resource garbage on a conveyor belt,
As in the conventional apparatus using a conveyor line formed in the shape of a scale, the garbage bag does not fall together with the resource refuse and the two do not mix. In addition, it is a structure that receives resource garbage on the inclined part of the conveyor line and separates the heavy garbage and the light garbage bag by using the difference in the falling speed of the garbage bag. There is no need for a compressed air flow or any device for adsorbing or scooping up the garbage bag, and the structure is extremely simple. In addition, since the pins are protruded from the surface of the conveyor belt on which the waste is placed, while dropping heavy and highly rigid waste,
Only a light and flexible garbage bag can be hooked on the pin and easily removed.

Further, the second auxiliary means is used to receive the garbage bags that have fallen along the inclined portion of the conveyor line, guide the received garbage bags to the resource garbage mounting surface of the conveyor belt, and attach the garbage bags to the pins. Because of the hooking structure, the refuse bag can be reliably removed from the resource refuse.

Further, since the third auxiliary means is used to press the garbage bag against a portion where the traveling direction of the conveyor belt is inverted downward along the surface of the winding drum, heavy and highly rigid resources can be conveyed. While being separated from the belt, the light and flexible garbage bag can be kept in contact with the resource refuse mounting surface of the conveyor belt and the pins, and both can be reliably separated.

Further, since the fourth auxiliary means is provided, the third auxiliary means is provided.
By means of the auxiliary means, the refuse bag kept in contact with the resource refuse mounting surface or the pins of the conveyor belt can be more reliably separated from the other refuse refuse.

Further, since the fifth auxiliary means is provided, the garbage bags which are entangled with the pins of the conveyor belt and conveyed in a suspended state can be reliably detached from the pins.
