[0002]

[Prior art]

 An inclined conveyor type sorting machine used for separating and collecting non-combustible lumps (concrete pieces, stones, etc.) and combustibles (wood chips, paper chips, etc.) in industrial waste is generally an incline type sorting machine (see 61-501685, etc.) and has a function of separating and recovering heavy objects (mainly non-combustible lumps) and light objects (mainly combustibles).

The structure of a conventional incline type sorting machine is, as shown schematically in FIG. 4, a belt conveyor 1 inclined in the width direction and the longitudinal direction, and arranged in a row or a plurality in a slightly oblique arrangement in the width direction of the conveyor. It has a row of motor driven rotating chain curtains 2 and has a structure in which a weight group 3 is hung at the lower part of the chain, and a resin or aluminum pipe 3-1 is used for the weight. There is. The waste is loaded from the side of the longitudinal end of the belt conveyor 1 and vibrates by a shaker (not shown) provided inside the belt conveyor. On the upper surface of the belt, heavy objects move in the conveyor width direction. After passing through the rotating chain curtain 2, it falls from the belt side end (lower part of the slope) and is collected, and the lightweight items are directly conveyed by the conveyor and collected at the end.

[0004]

[Problems to be solved by the device]

 However, the conventional incline type sorting machine has the drawbacks described below. (a) The gap a between the pipes hanging as a weight at the bottom of the rotating chain curtain is large, and a sufficient sorting effect cannot be obtained particularly for objects having a small grain size. (b) If a large amount of objects to be processed come into contact with the chain curtain at one time, the heavy objects in the objects may pass through the chain curtain when the gap between the pipes is expanded. , Light items such as combustibles are mixed in the sorted heavy items. (c) The impact after dropping the object to be processed adversely affects the sorting action.

This invention has been improved in order to solve the above-mentioned drawbacks of the prior art, and prevents an object to be processed having a small particle size or a lightweight object from coming out from the gap between the pipes and an object to be processed. It aims to provide an inclined conveyor type sorter that ensures the separation and recovery of heavy and light items by twisting the means for mitigating the impact after dropping.

[0006]

[Means for Solving the Problems]

 This invention comprises a belt conveyor inclined in the width direction and the longitudinal direction, and a motor driven rotating chain curtain arranged in a row or in a row slightly inclined in the conveyor width direction. Among the wastes introduced on the belt conveyor, the heavy goods pass through the rotating chain curtain and are discharged in the width direction of the conveyor, and the light weight goods are carried out by the conveyor. In order to prevent objects of small particle size or lightweight objects from passing through the rotating chain curtain, a flexible brush that contacts the upper surface of the belt is installed at the tip of the rotating chain curtain weight group in a divergent manner. An air injection pipe that injects air slightly upward to the inclined surface of the belt conveyor In addition to the flexible brush and the air injection pipe, in addition to the flexible brush and the air injection pipe, the upper surface of the belt is located inside the rotating chain curtain above the belt conveyor in order to reduce the impact after dropping. It is characterized in that a fixed type flexible brush which comes into contact is attached in the longitudinal direction of the conveyor.

[0007]

[Action]

 By installing a flexible brush that contacts the upper surface of the belt at the tip of the weight group of the rotating chain curtain, the gap between the pipes used as weights is completely filled, and the tip parts of all the pipes are connected. Exhibit a state of As a means for attaching the brush, for example, the bristles may be directly planted on the pipe itself, or a brush which is planted on a member separate from the pipe may be attached to the pipe.

The air injection pipe has a large number of air injection holes or slit-like injection holes on its side surface, and is arranged so that predetermined air is supplied from the air supply system, and is directed from the outside to the inside of the rotary chain cart. The air is installed near the contact area between the brush and the upper surface of the belt so that the air is sprayed upward. As the air to be injected, compressed air such as a compressor can be used.

The object to be processed that rolls or slides on the inclined surface of the belt conveyor is stopped by the rotating chain curtain disposed in the middle of the object, and is conveyed by the belt conveyor. At that time, since the lower part of the pipe of the rotating chain curtain is closed by the brush, the object to be treated or the lighter product smaller than the gap between the pipes is stopped by this brush and conveyed by the belt conveyor. On the other hand, heavy objects push the pipe or brush to spread, pass through the chain curtain, and fall from the bottom of the inclined surface of the conveyor. Also, if a large amount of material to be processed is thrown in at one time, there is a risk that a lightweight object will pass through the gap created by the brush or pipe being expanded by a heavy object, but it will be blocked by the air injected from the air injection pipe. It is transported by the belt conveyor without passing through the chain curtain.

Further, the fixed type flexible brush is hung inside the rotating chain curtain at an appropriate interval, and has a cushioning action to mitigate a drop impact of an object to be treated put on the belt conveyor. In other words, the object to be processed on the belt conveyor inside the fixed brush comes into contact with the fixed brush to mitigate the drop impact, and then reaches the rotating chain curtain. The drop impact of will not be directly applied to the rotating chain curtain. Therefore, it is possible to increase the vibration of the belt conveyor by using the fixed brush together, and it is possible to further improve the sorting accuracy and the collection rate of heavy and light objects.

 FIG. 1 is an enlarged front view of an essential part showing an example of an incline type sorting machine according to the present invention, FIG. 2 is a side view of the same sorting machine, 3-2 is a flexible brush, 4 is an air injection pipe, 5 Is a fixed flexible brush. The case where the rotary chain curtain is applied to an in-line type sorting machine with one row will be described.

That is, according to the present invention, a divergent flexible brush 3-2 is provided at the tip of each pipe 3-1 of the weight group 3 of the rotating chain curtain 2, and the gap between the pipes is filled with this brush. Form a wall. The flexible brush 3-2 is attached directly to the pipe itself, or is attached to the pipe 3-1 by a brush attached to another member. Each pipe 3-1 is suspended from a motor-driven chain 2-1 by a bolt 2-3 via a chain 2-2.

The air jet pipe 4 is arranged along the rotary chain curtain 2 so that air is jetted slightly upward in the vicinity of the contact portion between the flexible brush 3-2 and the upper surface of the belt of the belt conveyor 1. The air injection pipe 4 has a large number of air injection holes or slit-shaped air injection holes on its side surface, and one end thereof is connected to a compressed air supply pipe 5 such as a presser.

The fixed type flexible brush 5 has a structure in which it is attached to an L-shaped member 5-1 via a contact plate 5-2 with a bolt and nut 5-3, for example. It is hung from the inside of 2 by a hanging rod 5-4 at an appropriate interval.

In the above-mentioned incline type sorting machine, a process in which an object to be treated put on the belt conveyor 1 which is vibrated by a shaker (not shown) is conveyed by the conveyor. Are divided into those that roll or slide on the inclined surface (heavy objects, those that are light and easy to roll, etc.), and those that are transported as they are (such as those that are light and flat), of which the inclined surface What rolls or slides through, while passing through the fixed flexible brush 5 disposed in the middle of the inclined surface, moves further downward. When it reaches the rotating chain curtain 2 on the way, the lower part of the pipe of the chain curtain is closed by the flexible brush 3-2. It is conveyed by the belt conveyor 1 without being blocked by the curtain and passing through the curtain. On the other hand, the heavy object spreads the pipe 3-1 or the flexible brush 3-2, passes through the curtain, and drops downward. In addition, when the objects to be processed are collected or fall into a large lump, even if the weight of the chain curtain pushes the chain curtain to create a gap, the air injection pipe will be placed below the chain curtain. Since air is jetted from 4, the lightweight object is conveyed by the belt conveyor 1 without being blocked by the air and passing through the gap.
