SK280043B6 - Space mechanism for pointing belts which is balanced by centripetal rolling of belts - Google Patents

Abstract

A space mechanism for pointing belts which is balanced by centripetal rolling of belts is provided for pointing said belts based on a passive, continual regulation that origins when a change of the center position of a belt's continuous load on the guide roll occurs. Said guide roll is rotary positioned on a tilting holder in such a manner that by its tilting in the scope of action of the force from the belt onwards it results in consequential forced centripetal rolling of the guide belt. The space mechanism, due the length offset of a left and right belt thereof, is preferably used as a twin so that the successive space mechanism swivels through 180° in relation to the previous mechanism, from the view of the direction of the belts.

Description

Technical field

The invention relates to the field of kinematics of automatic systems, enabling passive continuous regulation of belt routing by balancing the spatial mechanism, forced by centripetal belt rolling.

BACKGROUND OF THE INVENTION

Previously known belt guiding devices are not developed on the principle of passive continuous control, but they are controlled by various active devices, such as side roll baffles or actively operated guiding rollers, which are deflected in order to center the webs by belt deflection sensors. Active belt routing is adversely affected by belt wear, as well as investment and operating costs due to the necessity of using sensors and active routing devices.

SUMMARY OF THE INVENTION

These drawbacks are largely eliminated by the spatial belt-guiding mechanism counterbalanced by the centering of the belt-forming rollers, which is rotatably mounted on a pivot bracket and is rotatably mounted in a stator, the pivot axis intersecting with the pivot bracket support center in the center around which the pivoting bracket tilts, according to the change in the position of the center of the continuous load when the belt buckles, so that by its tilting it causes forced centering of the belt on the directional roller until balanced, which is carried out continuously from both sides. the influence of the position of the pivot bracket axis which, when viewed from the direction of belt travel with respect to the deflection roller, is on the lower left front side and on the upper right rear side. The axis of the directional roller can be aligned with the height of the horizontal block and the axis of the pivot holder can be aligned with the body diagonal of the horizontal block.

The advantage of the solution of the spatial belt guiding mechanism according to the invention in comparison with the prior art is that, with its design simplicity and small stopping space, it allows continuous regulation of the belt guiding with high accuracy of straight belt travel with minimal lateral stress of the strips passively. In order to compensate for the length of the belt on its left and right side, it is advantageous to use two sequentially arranged double mechanisms, with the following mechanism rotated 180 ° relative to the previous one, which affects the change of bearing positions of the pivot bracket on the downstream roller. cylinder.
