Description

Vibration device for conveyors vibrant.

Object of the invention

The present invention relates to a Vibration device for vibrating conveyors. The end of the vibration generated is the transport of parts or particles to bulk that are transported along the conveyor channel vibrant.

The device comprises a reactive mass attached  to a means of producing vibrations that in turn joins a vibrating surface, the reactive mass also being connected and the vibrating surface by elastic means.

Characterizes the invention the fact that the vibration production medium comprises an electromagnet variable in frequency and voltage, the direction of understanding of the elastic means located at an angle sharp with respect to the vibrating surface thereby reducing the damping with a lower vertical amplitude which prevents the pieces move on the conveyor in big jumps, and  that due to the inclination of the elastic means is introduced a horizontal component of vibration that minimizes the vertical component

Background of the invention

Vibrating conveyors are known whose  surface on which the pieces to be transported move vibrates so that this vibration is transmitted to the pieces themselves that advance on it by jumping.

These vibration devices comprise essentially a source that produces the vibrations that is attached on the one hand to a reactive or fixed mass and on the other to its own vibrating mass Between both masses a vibration medium is established elastic that can be a spring or an elastomer that enters resonance with the vibrations produced by the source of vibrations so that the vibrating mass vibrates with an amplitude determined.

This vibration produced normally has a vertical component, in the case of low weight parts, this causes the jumps produced by it to be high which It can damage the parts and increase the noise.

The present invention solves the problem previous technician using a device that allows to achieve a horizontal component of the vibration so that the vertical component getting the jumps to finally be they cause the pieces to be smaller in height, so that take advantage of the speed of advance.

Description of the invention

The present invention relates to a Vibration device for vibrating conveyors. The end of the vibration generated is the transport of moving parts on the vibrating conveyor.

The device comprises a reactive mass attached to a means of producing vibrations that in turn joins a vibrating mass, in this case a surface by which move the pieces to be transported. The vibrating dough and the dough reactive are also connected by an elastic means, which would resonate with the vibrations produced.

The invention is characterized by the fact that the direction of understanding of the elastic means is located forming an acute angle to the vibrating surface achieving thus a damping with a smaller vertical amplitude what which prevents parts from moving on the conveyor vibrant at large jumps, because due to the inclination of the elastic means a horizontal component of the vibration that minimizes the vertical component.

With this position of the springs you get a  low damping as well as lower vertical amplitude when flexing parallel to the horizontal plane.

The pieces depending on the amplitude of adjustment they manage to move by defining a kind of parables with a greater horizontal component and a smaller vertical component.

Preferred Embodiment of the Invention

In figure 1 the device shown comprises  a reactive mass (1) attached to an electromagnet (10) which in turn joins the vibrating mass (5) that corresponds to a support of the guides between which the pieces to be transported run.

Therefore the means of production of vibrations comprises an electromagnet (10) variable in frequency and voltage.

Operation is achieved with the connection to the alternating or rectified pulsed electrical current adapting the frequency to the degree of rigidity of the system, varying the voltage of input to the electromagnet (10) or the frequency so that tune the system to the resonance point, getting the adequate amplitude of vibration.

The reactive mass (1) comprises elastic shock absorbers (11) in their connection to the floor or platform so that it is isolated from it.

The joining means between the reactive mass (1) and  the springs (12) comprise a side plate (2).

In the figure the springs (12) are placed in three  supports (3) thereof (12). The number of supports (3) comes determined according to the length of the conveyor.

Each support (3) is joined by one of its ends to the side plate (2), that is, to the reactive mass, and by another to the vibrating mass (5).

The electromagnet (10) is placed on a support (6) which is attached to the reactive mass (1). The support (6) is Adjustable and fixed electromagnet (10).

Additionally the supports (3) of the springs (12) are pivoting by varying the angle of the springs (12) with respect to the vertical, which allows to find the angle more suitable with respect to the vertical.

The guides or channels are fixed to the guide support (5)  through which the pieces or particles of solids move.

Finally both between each support (3) and the side plates (2) are placed at a distance (4) and on the Electromagnet (10) a protection plate (9) is placed.

It also includes a strap (7) that allows regulate and place a ballast that allows to find the center of gravity to achieve uniform amplitudes.
