The present invention relates to an automatic sorter for automatically classifying tubular metal materials used in automobile manufacturing according to diameter and length, as shown in FIGS. 1 to 11.

As a preferred configuration, the tubular metal material automatic sorter 100 of the present invention includes a cylindrical main body 110 in which a predetermined space is formed on the upper surface to accumulate the tubular metal material 10; A conveying path 120 spirally formed from the center of the body 110 toward the edge in order to guide the tubular metal material 10 scaled inside the body 110 to the edge side; It is formed at a predetermined height along the circumference of the body 110 at the edge of the body 110 to prevent the metal material 10 moved to the edge of the body 110 along the spiral transfer path 120 from falling to the outside. fence 130; A length sorting unit 140 and a diameter sorting unit 150 are configured in which the tube-shaped metal material 10 moving along the edge side circumference of the main body 110 is classified by length or diameter size and discharged. have.

At this time, the lower part of the main body 110 is configured with a rotation and vibration device for inducing the tubular metal material 10, which is scaled in the center of the main body 110, to move toward the edge along the transfer path 120. .

Accordingly, the tubular metal material 10 scaled on the upper part of the main body 110 by the driving of the rotation and vibration device installed on the lower side of the main body 110 moves along the spiral transfer path 120 to the main body 110. As it moves to the edge side of the body 110 in turn, it passes through the length selection part 140 and the diameter selection part 150 mounted on the edge of the main body 110 in turn, and the tubular metal material 10 is sorted at the designated position. will be.

In particular, the length sorting unit 140 selects the length of the tube-shaped metal material 10 discharged to the fence 130 so that the length smaller than the designated length among the tubular metal materials 10 can be discharged to the outside and sorted. A dragon selector 141 is formed.

More specifically, vertical brackets 142 are installed on both sides of the sorting tool 141 for length sorting, and a bar 143 for sorting length is installed horizontally between the pair of vertical brackets 142. It is configured so that both ends are bolted to the vertical bracket 142 so as to be placed in a straight line.

Accordingly, the height of the sorting tool 141 for length sorting is adjusted by varying the bolt fastening height of the horizontal sorting bar 143 according to the length conditions of the tube-shaped metal material 10 to be sorted.

The bottom surface of the transfer path 120 in contact with the fence 130 is inclined downward from the center of the main body 110 toward the fence 130, so that the sorting tool 141 for length selection formed on the fence 130 is formed.

In addition, the diameter sorting unit 150 has a plurality of diameter sorting units on the bottom surface of the transfer path 120 in contact with the fence 130 so that the tube-shaped metal material 10 is sorted according to the diameter size and discharged to the outside. Yong selection spheres 151 are formed to be spaced apart at regular intervals.

In particular, the sorting hole 151 for diameter screening has a wider width as it goes along the conveying path 120, so that the tubular metal material 10 having the smallest diameter is sorted first, and the next In the sorting tool 151 for diameter sorting, the second tube-shaped metal material 10 having a small diameter is sorted out.

In addition, a pair of horizontal brackets 152 are installed toward the outside of the main body 110 in the sorting tool 151 for diameter sorting, and a rod 153 for diameter sorting is installed between the pair of horizontal brackets 152. It is configured to be placed horizontally across and both ends are bolted to the horizontal bracket 152.

Accordingly, the width of the sorting tool 151 for diameter sorting is adjusted by varying the bolt fastening position of the rod 153 for diameter sorting in a horizontal state according to the size of the diameter of the tube-shaped metal material 10 to be sorted.

On the other hand, since the central portion of the upper surface of the main body 110 is formed in a predetermined groove shape in order to scale the tubular metal material 10, the transfer path 120 should be formed to be inclined upward gradually from the center to the edge side. will be.

In addition, a feeder 200 for supplying the tubular metal material 10 to the main body 110 of the classifier 100 is installed on one side of the classifier 100 .

More specifically, the feeder 200 of the present invention includes a hopper 210 in which the tubular metal material 10 is accumulated; One surface is in contact with the hopper 210 and is formed upright, and an inlet 221 is formed on the surface in contact with the hopper 210 to receive the tubular metal material 10 accumulated in the hopper 210 into the inside. And a transfer device unit 220 for transferring the tube-shaped metal material 10 introduced into the inside through the inlet 221 to the top by an upper transfer means installed therein ; A supply unit 230 having a discharge port 231 formed on one surface of the upper end of the transfer unit 220 toward the classifier 100 toward the top of the main body 110 of the classifier 100, through which the tube-shaped metal material 10 is discharged. );

At this time, the upper transfer means (not shown) mounted or installed in the transfer unit 220 can be implemented in various ways such as a transfer screw or an escalade method, which is a well-known technology, so that detailed descriptions are omitted in the present invention. do.

Inside the hopper 210 of the present invention, when the inclined surface 211 is formed inclined toward the inlet 221 of the transfer device 220 to contain the tube-shaped metal material 10 in the hopper 210, the tube-shaped metal material (10) was naturally driven toward the input port 221 of the transfer unit 220.

In addition, a control plate 222 for adjusting the amount of the metal material 10 introduced into the transfer unit 220 through the inlet 221 is mounted on the inlet 221 .

A pair of long holes 222-1 parallel to each other in the vertical direction are formed in the control plate 222, and bolts (reference numerals not shown) are bolted to the transfer unit 220 through the long holes 222-1. The height of the inlet 221 is adjusted by adjusting the vertical position of the control plate 223, so that the tube-shaped metal material driven into the inlet 221 by the inclined surface 211 inside the hopper 210 (10) It is possible to adjust the amount injected into the group transfer unit 220.

A handle (reference numeral not shown) that can be gripped by a worker may be formed at an upper end of the control plate 222 so that the operator can easily grip the handle, thereby increasing work efficiency.

In addition, a sensor 300 for measuring and detecting the amount of the tubular metal material 10 accumulated on the main body 110 is installed in the main body 110 of the classifier 100, and the sensor 300 When it is detected that the number of the tubular metal materials 10 accumulated in the body 110 is small, the upper transfer means mounted in the transfer device 220 is driven to remove the tubular metal materials 10 accumulated in the hopper 210. The tube-shaped metal material 10 is accumulated on the upper surface of the main body 110 through the supply unit 230 connected to the upper end of the transfer device unit 220 by moving the upper part.

At this time, the guide surface 232 is formed at the lower end of the outlet 231 to be inclined toward the upper surface of the main body 110 so that the tubular metal material 10 naturally falls of the main body 110 through the outlet 231. In addition, a 'L'-shaped blocking film 233 is formed at the upper end of the outlet 231 to prevent the tubular metal material 10 from protruding outward.

Since the sensor 300 controls the driving of the upper conveying means installed in the conveying unit 220, the mechanical actuating means and the electromagnetic means are also well-known and common means, so detailed descriptions thereof will be omitted in the present invention.

Therefore, the tubular metal material automatic sorter of the present invention can simultaneously classify tubular materials by length or diameter size within one device, and thus, it is cost-effective because a separate device is not required. It also has a significant effect from an economic point of view.
