Recycling, PET Bottle, Aluminum Can, Steel Can

Description

Aluminum Cans, Steel Cans, PET Bottles, Automatic Sorting, Small Volume Reducers {APPARATUS FOR AUTOMATICALLY SELECTING AND COMPRESSING ALUMINUM CAN, STEEL CAN AND PET BOTTLE FOR BEVERAGE}

The present invention compresses aluminum cans and steel cans of drank drinks sold in vending machines, convenience stores, supermarkets, etc., while dividing the cans into two buckets, storing the aluminum cans and steel cans in each bucket, and dividing the PET bottle into three parts. The compressed pet is crushed into a chip shape of 8 mm in diameter and stored in a bucket. The present invention dramatically improves the recovery efficiency by reducing the volume rather than directly recovering each empty container. The drainage left after drinking is recovered by the drainage reservoir. The present invention relates to a small volume reduction device for installation indoors and in the street.

In recent years, with the rise of petroleum fuel, recycling technologies have been fought to private companies for the purpose of recycling resources on a global scale. The domestic recycling processing apparatus is a plant apparatus by a combination of a crusher, a crusher, a cutting machine, and the like. Private machines are all large and have a high initial cost and high maintenance cost. The distribution is not good because this price is converted to recycled products. In addition to this point, the information of the mass comb also shows that the cost of collecting transportation, labor, etc. is enormous. In the compact processing apparatus, Japanese Patent No. 3000457 is only a crushing device for cans, and there is no countermeasure against drinking and leaving. The empty can volume reduction device of Japanese Patent No. 2784133 is a can dedicated machine. The empty can recovery device of Japanese Patent No. 3208572 is a can-only machine that sorts aluminum cans and steel cans by a deposition method, counts cans, and displays quantities.

Although Japanese Unexamined Patent Publication No. 3220017 beverage container collecting device is a can-only collecting device, the opening / closing mechanism of the compression mechanism is composed of a rack gear and pinion of a crank or cam moved directly from the reducer. The opening / closing mechanism is connected to the casing movable panel so that, during compression, the fixing panel absorbs shock from the spring, and is composed of a guide bar that eliminates the shock at that time. As a press mechanism, the compression force is structurally small. In any case, there are only a few items on the market in a can-only sorting machine or a small processing device equipped with a function of removing a bottle. It is almost nothing to see in the street, the side of the vending machine, or elsewhere.

Currently, PET bottles and empty cans have been increasingly discussed as environmental recycling issues, including local governments, due to increased collection, transportation, disposal, and labor costs associated with them.

Instead of being processed in an existing full-time factory, anyone can simply put a PET bottle and an empty can at the installation place, and they separate these into one. It is very small and there is no device that can simultaneously handle PET bottles, aluminum cans and steel cans. The present invention automatically deals with both low cost and high safety. In addition, the appearance can be produced in a plastic bottle or can shape, etc. as the user's request, and can be used in various ways as a advertising medium such as a beverage maker or a public notice board by attaching a liquid crystal display to the front of the main body.

When the person having the object of claim 1 is in close proximity, the photoelectric switch attached to the front of the main body reacts, and the control power is turned on, and when the aluminum can, steel can or PET bottle is placed on the inlet shutter, a metal sensor or a PET bottle sensor Is detected, and the shutter is opened and falls between the movable panel and the fixed panel of the compression press through the guide pipe. The movable panel is equipped with two cut knives made of two stages in the horizontal direction. Compresses while moving plate approaches fixed plate The ejector rod fixed to the fixed plate returns the stop plate, and the stop plate is opened.After the compression is completed, the stop plate is dropped and the compressed material of the divided bottle is divided from the gap to the next. Let's do it. In order to reduce the size of the main body, the cans to be processed are characterized by a small toggle compression press that divides the bottles into two parts and the PET bottle into three parts.

Detection by the metal sensor or the PET bottle sensor provided in the inlet shutter of Claim 2, Even if a thing other than a can or a PET bottle is placed on an inlet shutter, a sensor does not respond, an alarm sounds, and it notifies by a liquid crystal display and a voice. It is characterized by not mixing in the main body other than the designated processing material. The belt conveyor installed in the lower part of the shutter plate moves to the center of the lower part of the press and stops. The compressed can is dropped onto a belt conveyor provided with an aluminum sensor, and when the aluminum can is detected, the belt conveyor rotates left and is stored in a bucket for aluminum through a shooter. In the case of a steel can, since there is no detection reaction from the sensor for aluminum, the belt conveyor rotates right by a time lug and is stored in a steel bucket through a shooter. When the PET bottle is detected by the inlet shutter, the belt conveyor retracts, and the PET compressed in the stationary state falls to the inlet of the pulverized product of the pulverizer provided directly below the belt conveyor and pulverized. The sorting of the two divided aluminum cans and the steel cans is characterized by sorting on a small conveyor.

The compressed aluminum can and the compressed steel can which are divided into two parts and compressed into the storage bucket are stored in the bucket, respectively. The three-part compressed pet is crushed by a miniaturized compactor, and the three-part compressed pet in the grinding chamber is plate-shaped, which makes it easy to penetrate the rotary knife when it is dropped. If the digging is bad, avoid this by bouncing in, or moving around in, the grinding chamber. In addition, it is characterized in that forcibly pushed into the rotary knife by installing a pusher synchronized with the rotary knife in order to easily penetrate the rotary knife. Compression pipe and crushed PET are divided into two buckets and piled up in a stacked state like mountains. The uniform plate is pressed evenly by a uniform device to efficiently store the workpieces stored in the bucket of limited space. Repeat. Furthermore, a punched plastic bag with a diameter of 5 mm to 8 mm is covered so that the discharged liquid left in the storage bucket can easily leak and be easily collected. The discharged liquid is stored in the discharge tray installed under the bottom of each bucket, and is then transferred from the discharge tray to the discharge liquid reservoir by an absorption pump for storage. This device considers environmental hygiene and beautification. In addition, it is a compact volume reducer for aluminum beverage, steel tube, and PET bottle automatic sorting according to Claims 1 and 2, which is displayed on a liquid crystal display by a CCD camera provided with processing procedures of an inlet and a press / crusher, respectively.

The camera of the CCD1 provided in the front of the main body notifies with an alarm when placing an object other than a designated processing object on the inlet shutter plate, and recognizes an error by taking out the person on the liquid crystal display. The cameras of the CCD2 and CCD3 are devices aimed at drawing up the flow of processing conditions of the compression press and the pulverizer to improve the user's awareness of recycling.

The present invention is very compact and simultaneously handles PET bottles, aluminum cans, steel cans,

The cost is low and the safety is high. In addition, the appearance can be produced in a plastic bottle or can shape, etc. as the user's request, and can be used in various ways as a advertising medium such as a beverage maker or a public notice board by attaching a liquid crystal display to the front of the main body.
