SU465233A1 - Device for sorting and sorting according to the length of parts from ferromagnetic material - Google Patents

Description

one

The invention relates to a measuring technique, in particular to control and sorting devices for sorting parts such as a rod with a head (nails, screws, rivets, etc.).

A device is known for grading and sorting along the length of parts made of ferromagnetic material, for example nails, containing I1, its vibroboucker, tray, sorting and sorting unit and receiving bins.

In order to increase the productivity, the screening and sorting unit is made in the form of a drum with a brush and combs with teeth, the drum consisting of a set of multiply magnetized discs separated by diamagnetic spacers, and the tooth of the combs is inserted into the gaps between the discs at various levels.

FIG. 1 shows the proposed device, side view; in fig. 2 - the same plan view; in fig. 3 shows a section along A-A in FIG. 2 and a drum reamer with combs.

A device for sorting along the length of parts made of ferromagnetic material consists of a vibrating hopper 1, a trap tray 2 for orienting and transporting parts, a drum 3 containing a set of magnetized disks 4 between which there are diamagnetic gaskets 5 having a smaller diameter than magnetized drives. The grooves 6 are located along the forming surface of the drum, the depth of which is equal to or more than the diameter of the core of the part. In the course of the rotation of the drum, a brush 7 is installed, in contrast to removing parts protruding beyond the limits of the drum forming the surface of the drum, i.e., bent products, and the comb 8 with the teeth 9 located between the discs at different levels. In rotation, the drum with the brush is driven by an electric motor 10. Underneath each comb are receiving hoppers And for sorted parts of the same size.

The device works as follows.

Parts from vibrator-bumper I enter the inclined chute 2, where they hang on the heads and slide to the drum 3 in the orientation groove. The gap between the inclined chute 2 n forming the surface of the rotating drum 3 is 1/3 of the diadeter of the core of the part, which prevents them stick anywhere on barabaia. Parts made of ferromagnetic material, inserted into the grooves 6 of the drum, are held in the npx due to the magnetic field formed by the magnetized disks 4, and rotate together with the machine r driven by the electric motor 10. The diamagnetic pads 5 are placed between the bottoms with different polarity. The intact part passes by the brush 7 (the deformed part is removed) and enters the zone where the combs 8 with the teeth 9 are located. The tooth 9 is located between the magnetized disks 4 at different levels. The number of combs with teeth and gaps between the disks is equal to the number of sizes of the sorted parts. First, parts of greater length are removed (the first comb along the rotation of the drum with a tooth located in the lower gap between the drum disks), then the parts of the next size are removed, etc. The sorted parts fall into the receiving bins 11.

Subject of inventions

A device for sorting and sorting along the length of parts made of ferromagnetic material, such as nails, containing a vibrating hopper, a tray, a sorting and sorting unit and receiving bins, characterized in that, in order to increase its performance, the sorting and sorting unit is made in the form of a drum with a brush and a comb with teeth, the drum consisting of a set of oppositely magnetized discs separated by diamagnetic spacers, and the tooth of the comb entering the spaces between the discs.
