Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention separates light and flexible objects such as vinyl bags and paper bags from garbage in which relatively heavy substances such as glass bottles and empty cans are mixed. The present invention relates to an apparatus for performing the above.

[Conventional technology]

Conventionally, as a device for separating and sorting materials having different specific gravities as described above, a wind force sorting device using wind power is generally used.

Such a wind power sorting device faces an air outlet and a suction hood that sucks air, and a light substance that is sucked together with air by passing a substance to be sorted during this time.
It separates heavy substances that are not sucked.

In this case, a means for dropping the substance to be sorted by its own weight or sending it substantially horizontally by a vibrating conveyor or the like is used.

[Problems to be Solved by the Invention] In the conventional wind separation apparatus as described above, in the method of dropping the substance to be sorted by its own weight, the passing speed of the substance is high, and the mass of the substance to be sorted is not loosened. If a vibrating conveyor is used, the material to be sorted passes directly over the air outlet, resulting in clogging of the air outlet and heavy materials falling into the air outlet. There is. Also, from the supply and discharge sections of the substances to be sorted,
Since unnecessary air is sucked in the sorting, the amount of air sucked from the suction hood must be increased.

In addition, there is a problem that the garbage in the vinyl bag cannot be separated by air flow as it is, so that it is necessary to break the bag to make the contents.

The present invention takes into consideration the various problems described above, and uses light weight and heavy trash mixed together by its own weight, and when both are lumped together, it is necessary to disassemble the trash and put it in a garbage bag. An object of the present invention is to provide a collected garbage separation apparatus which can surely separate garbage, even if not contained in a garbage bag, and which can be manufactured at a economical cost as a simple mechanism.

[Means for solving the problem]

In order to solve the above-mentioned problems, the present invention fixes a plurality of rows of protruding pieces in which a plurality of protruding pieces are linearly arranged at appropriate intervals on an outer side of an endless belt arranged obliquely upward with a predetermined width, and An apron conveyor having a transport side running diagonally upward on the upper side thereof, and a roll feeder provided on the apron conveyor and having a plurality of claws protruding in a multi-row radial pattern on the outer periphery of the drum and provided in each row of the roll feeder The pawls are disposed so as to be located between the protruding piece rows of the apron conveyor, and the roll feeder is rotationally driven so that the lower pawls move in a direction opposite to the conveying direction of the apron conveyor. An object of the present invention is to provide a collected waste separating apparatus configured to separate waste dropped from an input port located above a roll feeder into a heavy load and a light load.

[Action]

The collected garbage separation apparatus of the present invention having the above-described configuration separates both bulk garbage and garbage in a garbage bag into heavy objects such as bottles and cans and light objects such as garbage bags and paper. Acts to be. The thrown garbage is separated into heavy and light objects by the weight difference using the inclined surface of the apron conveyor.

Among the input waste, heavy objects such as bottles and cans fall by their own weight even if the rotation of the endless belt is in the reverse direction, with the space between the protruding pieces as guide grooves. Conversely, a light weight object such as a garbage bag is pierced by a protruding piece and broken, and after the heavy object falls, is lifted upward by an endless belt and separated from the heavy object.

Regardless of whether the garbage is in the garbage bag or not, the garbage may be thrown into a lump with heavy materials mixed with the light-weight material. In some cases, the garbage cannot be sufficiently separated into heavy and light objects just by dropping the waste. In such a case, the input refuse is pressed by the roll feeder and the refuse bag is broken by a row of protruding pieces of the apron conveyor, and if the refuse is lump, the lump is loosened by the claw of the roll feeder. For this reason, the heavy object is separated from the light object and the heavy object falls under its own weight, and the light object is lifted upward by the conveyor and sufficiently separated from each other, so that the refuse in any state can be separated, and the separation efficiency is improved.

Driving means 9 is provided, and the output shaft and the pulley 4 are linked by an endless transmission chain 10 to drive the belt 6 in the direction of the arrow in FIG.

The upper ends of the left and right frames 1 are inclined forward and downward, and the upper front ends thereof and the lower front ends of the left and right support frames 3 are connected by left and right hydraulic cylinder mechanisms 11 so that the inclination angle of the support frames 3 can be freely adjusted. To do.

In FIG. 1, reference numeral 12 denotes a roll feeder mounting frame, and lower ends of support legs 13 at lower left and right sides thereof are rotatably mounted by a shaft 14 near rear portions of the left and right support frames 3.

The roll feeder B mounted on the mounting frame 12 has a plurality of claws 18 protruding in multiple rows and radially on the outer periphery of a drum 17, as shown in FIG.

The drive means 20 is composed of a motor and a speed reducer, and has a variable speed. The output shaft and the drum 17 are linked by a transmission chain 21.

The front ends of both sides of the mounting frame 12 and the lower ends of the both arms 8 are connected by a hydraulic cylinder mechanism 23 to form a roll feeder B.
And the distance between the apron conveyor A and the apron conveyor A can be freely adjusted.

C is a feeding device comprising a conveyor 25 and a sorting device 26. In this device 26, a pair of left and right sorting plates 28 swinging about a shaft 27 and an interlocking mechanism 29 'for linking the two plates 28 are provided.
And a switching means 29 for switching the distribution plate 28 to the right or left. A lid 30 that can be opened and closed is provided at the lower end opening.

Further, a discharge chute 32 of a light substance such as vinyl or paper is integrally provided at the front end of the apron conveyor A, and a fixed chute for dropping the discharge material falling from the chute 32 onto the discharge conveyor 33 at the front of the frame 1. 34 will be provided.

Behind the frame 1, a garbage bag is broken on the apron conveyor A, or a bottle and cans for discharging jars and cans from which light and heavy mixed garbage are unraveled and dropped.
A fixed chute 36 to be dropped onto 35 is provided.

As shown in FIG. 3, the belt 6 is provided with a number of rollers 38 on the back side, and the rollers 38 are supported by guide rails 39 arranged on the transport side. On the return side, only the rollers 38 on both sides are guided by the guide rails. Supported by 39.

Next, the operation of the above embodiment will be described. For convenience of explanation, the garbage shown in FIG. 4 is described as being in a garbage bag. However, in this embodiment, separation processing can be performed even if the garbage is not necessarily in a garbage bag. While the lid 30 is opened, the apron conveyor A and the roll feeder B are driven in the direction of the arrow in FIG. 4 while a relatively bulky material such as a vinyl bag or a paper bag is used. As shown in FIG. 4, waste containing a substance having a high specific gravity is fed from the conveyor 25 to the roll feeder B via the sorting device 26.

If the input garbage is in a bag, put it in a garbage bag
At 37, the bag is torn by the claw 18 of the roll feeder B and the projection 7 of the conveyor A. In this case, the claw 18 of the roll feeder B presses the garbage bag to facilitate tearing the garbage bag. As a result, the light-weight substance 40 such as a garbage bag is caught by the protruding piece 7 and transported upward, and is carried out by the conveyor 33 via the chutes 32 and 34,
A heavy substance 41 such as a bottle or a can which has come out of the garbage bag is guided between the projecting pieces 7 as guide grooves, slides down on the conveyor A, passes through the gaps, and is carried out by the conveyor 35 via the chute 36.

If the garbage is not in a garbage bag but light and heavy persons are entangled with each other and are in a lump, or the lump is still lumped out of the litter bag, the lump is in the roll feeder B. When hit by its own weight, claw 18 of roll feeder B
Is rotated and unraveled, and light and heavy objects are broken apart. Therefore, the heavy substance and the light substance do not remain mixed with each other, and both are separated more reliably.

In addition, the cylinder mechanisms 11 and 23 are expanded and contracted according to the size of the refuse to adjust the inclination angle of the apron conveyor A and the interval between the apron conveyor A and the roll feeder B, and also adjust the speed of the belt 6 and the drum 17. It is good to be in the optimal state.

〔The invention's effect〕

As described above, the present invention has an apron conveyor having a large number of protruding pieces arranged outside an endless belt arranged obliquely upward, and a plurality of claws located on the apron conveyor and having a large number of claws radially around the drum. It consists of a roll feeder, and the claws of each row of the roll feeder are arranged between the protruding rows of the apron conveyor, and the roll feeder is rotated in the opposite direction to the apron conveyor. If non-recyclable garbage is thrown in from the slot on the roll feeder, the garbage bag is torn by the conveyor's protruding piece moving in the opposite direction and the roll feeder's claw. The contents and the bag are separated. In the case of a garbage bag, or a mixture of light and heavy objects that are not in a garbage bag but are mixed together, the garbage is disentangled by the claw of the roll feeder, and the light and heavy objects are separated apart. Among the separated waste, bottles and cans with relatively high specific gravity, such as bottles and cans, slide down between the projecting pieces of the conveyor and are discharged downward, while bulky and lightweight ones such as vinyl bags and paper bags are used as the projecting pieces of the conveyor. And is transported upward and discharged. Therefore, light waste and heavy waste can be separated without using a large facility such as a blower as in a conventional wind separation device.
