Description

one

The invention relates to the field of transportation of piece objects and can be applied in the engineering industry.

A known method of supplying parts to the working position is by means of a vertically arranged discharge chute or pipe, which is reported to vibrate, directed perpendicularly to the movement of the parts 1.

A disadvantage of the known method of transportation is the impossibility of supplying the parts upwards, since this method of drying only allows the release of the pieces.

The closest technical solution to the invention is the method of vibratory transport of piece objects by directed oscillations of the load-bearing surfaces 2. The drive of the machine communicates oscillatory movements to its load-bearing organ, creating a potential, which overcomes the loads of the mixed, the object and the internal resistances, as well as the forces of inertia oscillating their masses or restoring, and the strength of elastic connections.

The disadvantage of this method of transportation is low speed due to insufficient contact of the objects being moved with the cargo carrier, the body.

Devices are known for drying, the method of vibrational transporting, including a pipe or chute working body driven in an oscillatory motion by vibrators with two coaxial unbalances associated with electric motors mounted on a mobile

plate, connected to the working body by springs and with non-idol base by means of a rod 3.

However, these devices are not productive enough due to the small amplitudes

oscillations of the transported material.

The closest technical solution to this invention is a device for implementing a method of vibratory transport, including

vibro drive and carrying tray 4.

In the known vibrating conveyor, the load-carrying body consisting of two parallel-arranged trays moving relative to each other, form a common overpass for the material being transported. An equilibrating frame is installed along the trays, connected to each of the trays by elastic connections, and the direction of the elastic connection of the frame to one

the tray forms an angle in the longitudinal plane with the direction of the elastic connection of the frame with another tray.

The disadvantage of this device is the low transport speed due to insufficient contact of the materials being transported with the load-carrying body.

The aim of the invention is to increase the speed of transportation due to the elastic throw.

This is achieved by subjecting subjects to elastic pinching by the vibrating surfaces and then releasing them from being pinched at the moments when the maximum speed is reached. At the same time, the load carrying tray is provided with parallel guides for transported objects, fixed on the tray by means of springs with the possibility of elastic clamping of the guides of the transported objects.

FIG. 1 shows the movement pattern of the transported object; in fig. 2 - oscillation trajectories of the carrying body; in fig. 3 — the subject was pinched by cargo carrying surfaces; in fig. 4 is a device for transporting piece objects, a general view; in fig. 5 shows section A-A in FIG. four.

The vibro-transport of the soft objects is carried out as follows.

Item 1 to be transported is fed into the slot formed by the load carrying surfaces 2, which make elliptical vibrations from the vibrating actuator 3. The transported object, touching at points B with load carrying surfaces, from point B to B receives an elastic pinch with the message of maximum acceleration flight with the subsequent release of pinching.

At points B, the object receives an additional impetus due to the elastic throw of the load-carrying surfaces - see FIG. 1, where RI is the force of elasticity carrying

surfaces;

RZ is the force imparted to the object by the oscillating load-carrying surface; R is the resultant force;

T - the flight path of the object; a is the angle of oscillations of load-carrying surfaces; Р-Р - the plane of the pinched objects;

Р-Р - the plane of the release of objects from pinching. A device for carrying out the method consists of a base 4 of the active part, on which, by means of racks 5 and flat springs 6 attached under a sharp fragile p to the base, guides 7 are mounted, which serve as load carrying surfaces.

The invention allows to significantly increase the speed of vibro-transport of piece objects and the productivity of transport installations.
