Description

one

The invention relates to the vibration transport of goods and can be used, for example, for supplying piece blanks to the working area of various machines, counting machines, assembly machines and control machines.

Vibrating feeders with independent torsional and axial vibrations of the working member are known, including working and reactive masses, interconnected by elastic systems of torsional and axial vibrations.

However, the known feeders do not provide a constant level of the working body relative to the supporting surface of the feeder, as they are installed on the ground by means of shock absorbers.

The aim of the invention is to maintain a constant level of the working body relative to the support surface of the feeder.

For this, the proposed vibrating feeder is provided with an intermediate mass, which is connected by one side with elastic elements to the working and reactive masses of axial vibrations, and the other side with elastic elements to the reactive mass of torsional vibrations, the elastic system of torsional vibrations being rigidly fixed on the supporting surface of the feeder .

FIG. 1 is a schematic diagram of a feeder; in fig. 2 - feeder, longitudinal section. Working body 1, intermediate mass 2

and the reactive mass of 3 axial oscillations are successively connected by elastic elements 4 and 5 (plastic springs), while the mass of the working body and the reactive mass of axial oscillations, as well as the stiffness of elastic

elements are selected in such a way that the intermediate mass remains stationary.

The intermediate mass 2 by the elastic system 6 of torsional vibrations is connected to the reactive mass of 7 torsional vibrations. By the nondeformable parts 8 of the elastic system of torsional vibrations, the entire structure is rigidly fixed to the supporting surface of the feeder. The working body 1 nitatel (see Fig. 2) is made in the form of tea, bonded with bark 9

vibrator vertical oscillations of a pair of spaced apart flat springs 4, and is connected to an intermediate mass 2, made in the form of a flange. The reactive mass of 3 axial oscillations is an electromagnet of a vertical vibrator connected to the flange by a pair of flat springs spaced apart 5. Intermediate mass 2 by an elastic system 6 in the form of a white squirrel torsion with a reactive mass of 7 torsional vibrations. Torsional vibrations are excited by two electromagnetic vibrators located symmetrically with respect to the axis of the feeder. The electromagnets 10 are fixed on the reactive mass of 7 torsional vibrations, and the core 11 on the intermediate mass 2.

In the non-deformable parts of the torsiop, protrusions are made, with which the entire structure rests on the base 12. Thus, the feeder is attached to the base absolutely rigidly, which ensures a constant level of the working body relative to the supporting surface of the feeder.

The feeder works as follows. With the help of electromagnets 3 and 10 vibrators, axial and torsional vibrations are excited in the system. By changing the magnitude of the disturbing forces and introducing a phase shift between axial and torsional vibrations, a non-separable mode is provided.
