Description

one

The invention relates to the field of machine tool construction, in particular, to discharging devices for dispensing parts processed in a vibratory installation.

A discharging device is known, which provides for the delivery of parts processed in a vibratory installation, which contains a magnetic drum with a belt conveyor clinging to it and equipped with a de-magnetizer at the outlet.

However, in this device, due to the cylinder-shaped magnetic drum, contact with the conveyor belt surrounding the drum occurs at the line or at a point depending on the shape of the part, which does not ensure reliable adhesion of the latter with the drum.

The proposed device differs from the known one in that the magnetic drum is made in the form of a multi-sided prism, along the side surface of which, through one face, horseshoe-shaped magnets with the width equal to the width of the drum face are installed with opposite poles.

This provides an increase in the strength of the detailing effect on the surface of the magnetic drum.

FIG. 1 shows schematically a vibratory installation with the proposed unloading device; on fng. 2 - located magnets along the edge of the drum.

The device includes a housing J, on which magnetic 2 and leading 3 drums are connected, connected by a belt conveyor 4, a drive consisting of an electric motor, a gearbox and a coupling (not shown), tensioning rollers 5 and orienting guide elements made in prism-shaped 6. Magnetic drum 2 is made in the form of a multifaceted prism, along the edges of which, with an interval of one face, horseshoe-shaped magnets 7 are fixed, filled with a hardening composition on a base

epoxy resin. The working planes of the magnets 7 form the faces of the drum 2 and are located opposite each other to one another, and the width of the magnet is equal to the width of the face. At the exit from the conveyor 4 unloading

the device is weakly inclined tray 8, made of a diamagnetic material, such as PCB, and mounted on the body with the ability to change the angle of inclination. On the tray 8, the coil of the demagnetizer 9 is fixed so that the plane of sliding of the part passes inside the coil.

On the frame 10 vibratory installation with a vibrator // along the working chamber 12 is fixed two racks 13, each nz which

coaxially located cylindrical rod

14 with a rack in the middle part, interacting with the gear 15. The rod 14 in the upper part is made in the form of a supporting prism, the taper of the groove and dimensions correspond to the taper and the dimensions of the prisms 6 fixed to the body of the discharge device. The distance between the rods 14 is equal to the distance between the prisms 6.

After the end of the machining cycle, the unloading device with the aid of: a telpher is guided to the working chamber 12, orient the magnetic drum 2 relative to the chamber 12, and are mounted with conical trims 6 on the support prisms of the rods 14, which are in the extreme upper position before unloading. Then, if necessary, the hoist is retracted from the axis of the vibration unit (or the suspension cable is loosened) and the device power supply cable is connected to the electrical equipment of the installation using a plug connector. The unloading is carried out with the installation vibrator operating. Turn on the rotation of the magnetic drum 2 and lower the discharge device into the working chamber 12. Machined parts, nP

moving on the surface of the medium, attracted by permanent magnets 7 to the drum 2, are removed from the working chamber 12 and dropped along the conveyor 4 to the tray 8.

With the passage of parts on the tray, they are demagnetized by means of a demagnetizer 9 fed by alternating current. The unloading device can be transported by a hoist to service a number of vibration installations.

Subject invention

A removable unloading device for dispensing parts processed in a vibratory installation, the magnetic drum of which is enclosed by a belt conveyor equipped with a de-magnetizer at the outlet, characterized in that, in order to increase the force of adhesion of the parts to the surface of the magnetic drum, it is designed as a polyhedral prism along the the surfaces of which, through one facet, are attached by opposite poles to one another, horseshoe-shaped magnets whose width is equal to the width of the drum face.
