After being crushed, it is transported to various sorters in order to make it recoverable as a resource. If a long object is present in the transport process, the long objects are entangled with each other, and there is a problem that good transport cannot be performed. Therefore, it has been proposed to provide a length sorting device including a rotating shaft, a rotating plate, a long object engaging rod, and a long object engaging claw at a discharge portion of a conveyor that conveys an object to be sorted (practical use). See new model registration No. 3031853).

[0003]

The above-described length sorting apparatus has a problem that the construction is complicated and the manufacturing cost is high, and that it is not possible to adjust how long a long object is excluded.

SUMMARY OF THE INVENTION An object of the present invention is to provide a length sorting apparatus which has a simple structure and can surely sort an object to be sorted into two long and short levels.

[0005]

SUMMARY OF THE INVENTION A length sorting apparatus according to the present invention comprises a vibrating conveyor for transporting an object to be sorted in which a long object having a predetermined length or more and a short and granular material having a length less than a predetermined length are mixed, A long object receiver provided with a short / granular object falling gap at a discharge part of the conveyor, and a long object aligning recess extending in the conveying direction is provided on a conveying surface of the vibrating conveyor. .

[0006] The objects to be sorted placed on the vibrating conveyor are gradually conveyed by vibration. At this time, the long objects that have been directed in a separate direction are aligned with the long objects arranged on the conveying surface of the vibrating conveyor. The recesses are aligned in the length direction. In addition, the entangled long objects are also loosened by the vibration, and aligned in the length direction of the long object alignment concave portion. Therefore, the long object is transferred to the long object receiver without falling from the short / granular object drop gap, while the short object / particle object is dropped from the same gap and received by the belt conveyor or the like to be collected. Then, it is sent to the valuables sorting device in the next process.
The long object accommodated in the long object receiver can be easily cut into a short length by a cutter, or may be returned to the crusher.

The long object receiver is in the form of a discharge chute or discharge conveyor. The long object aligning concave portion is obtained by forming the conveying surface of the vibrating conveyor into a U-shape, a V-shape, an inverted V-shape, a waveform, or the like.

[0008] The long object receiver is preferably movable so that the gap between the short and granular objects can be adjusted.
In this way, the short / granular object falling gap can be changed as required, and the length of the long object can be freely set. In order to move the long object receiver, for example, a rack and pinion mechanism is used.

It is preferable that the conveying surface of the vibrating conveyor has a V-shaped cross section and the opening angle thereof is adjustable. In this way, when the entangled long object gets stuck, the jam on the conveyor can be released by increasing the angle of the V-shape.

At this time, the long objects (L) facing in the separate directions are replaced with the long object alignment recesses. (7a) It is aligned in the length direction. Further, the entangled long object (L) is also loosened by the vibration and aligned in the longitudinal direction of the long object aligning concave portion (7a). Therefore, all the long objects (L) are transferred to the long object receiver (3) without falling from the short / granular object falling gap (G). On the other hand, the short / granular material (S) falls from the short / granular material falling gap (G). Sorted objects dropped from the belt conveyor (1) onto the vibrating conveyor (2) may form a large lump,
Since this large lump is broken by vibration, it is not necessary to separately provide a leveling plate for leveling the large lump to a uniform height. In addition, there is a case where the long object (L) is not loosened while being intertwined, but even in this case, the short object and the granular material (S)
Is dropped from the short / granular object falling gap (G), and the long object (L) is transferred to the long object receiver (3) while being entangled.

A short / granular material collecting belt conveyor (12) is provided below the short / granular material falling gap (G), and the short / granular material (S) is conveyed by the belt conveyor (12). It is sent to the valuables sorting device in the next step.
