Abstract

PROBLEM TO BE SOLVED: To provide a method and a device of sorting into an article other than a spherical one and a large article, and a spherical and smaller article without clogging or the like.SOLUTION: In a method of sorting an object to be sorted which is close to a spherical shape, and an object to be sorted which is far from the spherical shape, the object to be sorted is input from a mouth on an upper side of a cylinder rotated diagonally downward, only the object to be sorted having a shape far from the spherical shape is made to arrive in a periphery of an upper surface by rotating in an inside of the cylinder by friction force or interference with an inner side surface or an inside protrusion of the cylinder, and the object to be sorted, which is peeled from the periphery of the upper surface and falls, is guided to a predetermined position outside the cylinder by an in-cylinder guide. A large object to be sorted is similarly guided.SELECTED DRAWING: Figure 1

Description

The present invention relates to a sorting method and a sorting apparatus. In particular, the present invention relates to a method and apparatus (such as a machine) for sorting metal shredder waste.

When shredding the thin steel plate scrap generated at the factory as a casting material (so-called “new shredder scrap”), depending on the state of the iron plate scrap to be input and the processing conditions, the “fist size” and “ping-pong size” are easy to manage in the subsequent process. "Spherical shredder scraps that are far from" spherical "(string, plate, jellyfish, etc.) may be generated. It has been.
In order to realize this, only those having a preferable size and "spherical shape" by a trommel having a configuration close to the following Patent Document 1 "Solid food size sorting apparatus" or a simpler filter screen plate. There is a method for sorting out from other sizes and shapes.
However, in these methods, the object is often clogged in the holes of the screen and the filter (only those having a suitable size and shape are passed). Further, when selecting metal, a cushion (spring or The mechanism for preventing clogging such as the adjuster) was immediately damaged.

Provided is an apparatus for selecting a selection target having a size less than a predetermined size and a selection target having a size not less than a predetermined size.
According to the present invention, the inner projection is formed in a mountain-like shape, a slope-like shape, or both in the direction of hitting the sorting target by rotating the cylinder, so that the “spheroid-shaped sorting target” 6 a It is possible to prevent jumping by meeting the protrusion.

Since this method does not have a hole in the first place, there is no worry about clogging, and there is no need for a cushion, and it solves the problems of the conventional method.

It is explanatory drawing explaining the method and apparatus of one Embodiment of this invention. However, the shredder waste (work) 6 to be selected and the in-cylinder protrusion 1d are not shown. Similarly, it is the perspective view seen from the mouth side which throws in the shredder waste which is a workpiece | work. The in-cylinder protrusion is also clearly shown. It is a perspective view which shows a mode after throwing the spherical non-standard shredder waste and the rod and plate-shaped non-standard shredder waste into the injection port side of a cylinder. It is a perspective view for demonstrating the motion of the workpiece | work inside and outside a cylinder from the exit side. It is a front view of one embodiment by the present invention. 1 is a side view of an embodiment according to the present invention.

FIG. 1 shows an exemplary embodiment according to the present invention.
Stainless steel cylinder 1a (horizontal inclination 30 degrees, thickness 22 mm, inner diameter 1000 mm, rotated counterclockwise (clockwise toward FIG. 2) by servo motor 1b whose structure and wiring are not shown, A flange 2 is provided so as to penetrate the cylinder 1 from a position close to the upper surface inside the roll bearings 1c and 1b and the servo motor drive 1b) with a length of 1000 mm and reinforcing the outer periphery of the entrance and exit. 2 exits from the lower opening of the cylinder 1 and comes out farther from the bottom of the cylinder 1 so that a “sorting object of a shape far from the spherical shape” (bar, plate, etc.) 6b can be sorted outside the partition plate 3.
Along the inner side of the cylinder 1 (depending on the amount of friction due to the shape and the ease of being carried by the inner projection (s)) than the “spherical shape selection target” 6a (spherical fist size etc.) The “sorting object of the shape far from the spherical shape” 6b (bar, plate, etc.) rotated to a higher position falls to this ridge 2 and is far from the lower mouth of the cylinder 1 along the ridge 2 (of the partition 3). It is possible to sort out to a position different from “a selection object having a shape close to a spherical shape” 6a (from the lamp 4 in front of the partition 3).
As shown in FIGS. 2, 3, 4 and 5, the wall on one side of the ridge 2 can be made high so that the “sorting object of a shape far from the spherical shape” 6b does not jump over the ridge (in the figure, it is made high). ing).
With respect to sorting by dimension, a sorting object having a large dimension is more susceptible to the center of gravity of the plurality of discrete protrusions 1d inside the cylinder and the sorting object 6b than a sorting object having a small dimension (interference frequency, The number of simultaneous interference sites, the interference area, etc.) interfere and rotate to reach a higher position, so that such selection is possible.
The selected shredder scraps (6a and 6b) can be managed by being separated into an industrial waste box placed under the discharge lamp 4 and an industrial waste box placed outside the partition plate 3.
Although not shown in the figure, the rotating in-cylinder stirring protrusion 1d has a mountain-like and slope-like direction in which it comes into contact with the selection target so that the surface that contacts the workpiece does not meet the spherical shape but easily meets the plate or bar shape. By adopting (the shape with a sharper ridge at the top of the mountain), it is possible to prevent the “spherical shape selection target” 6a from bouncing up like a plate or a bar, and hindering selection. I can do it.
