Title of the invention

Device for moving and transporting tubular items

Field of application of the invention

The invention relates to a device for moving tubular or rundstabförmigera Behandlungsgut about its longitudinal axis (rotation) and to its transport transverse to its longitudinal axis, for example in plants for chemical or electrochemical surface treatment.

Characteristic of the known technical solutions

The. known principles for moving tubular or round rod-shaped material to be treated about its longitudinal axis are free rolling on inclined planes or curves (rocking movement of the Behandlungsgutauflage), guided rolling on inclined planes or curves (sliding movement of Behandlungsgutauflagen), guided rolling by pressing a moving element (friction wheel) and local rolling on rotating elements.

The known principles for the transport of tubular or rundstabförmigera Behandlungsgut transverse to its longitudinal axis are free or «guided rolling over inclined planes or curves, guided rolling by pressing a moving element (Reibradprinzip, pushing movement by means of forks or pawls, movement by means of conveyor belts or transport chains and in accordance with Federal Republic of Germany patent 15 4-6 movement by means of star wheels.

Although the principles of the rocking movement or the sliding movement of the Behandlungsgutauflagen and the pressing of a moving element can be combined relatively favorable with the corresponding transport port principle, however, have the disadvantage that the position of the material to be treated is not fixed during its movement about the longitudinal axis.

However, the fixed position of the material to be treated during movement about its longitudinal axis is of great importance for various chemical and electrochemical treatment methods, e.g. for internal pipe walls (flooding).

The principle of local rolling on rotating elements ensures the fixation of the material to be treated during its movement about its longitudinal axis; However, the transport must be in a known manner according to a separate, non-combinable principle, ζ; Β. by pushing movement by means of forks or pawls, done.

Object of the invention

The invention has for its object to provide a device both for moving tubular or round rod-shaped items to be treated around his. Longitudinal axis in a fixed position as well as to its transport transversely to 'its longitudinal axis on the basis of a uniform functional principle to create, which does not impair its high surface quality with optimum positional and transport safety of the material and which is suitable for use in chemical or electrochemical surface treatment ,

Explanation of the essence of the invention

According to the invention the object has been achieved by a device was created on the principle of local rolling of the material to be treated on rotating elements, which allows both the movement of the material to be treated and its transport.

On parallel, in-plane axes rotating elements are arranged so that each on adjacent axes

facing elements, i. e. the bearing radii R 1 of the elements are greater than half of the axial distance R 2. The material to be treated is in a fixed position in the "prisms" formed by the intersecting elements.

In a same direction, reversing rotational movement of the axes rotates the .Gehandlungsgut about its longitudinal axis. The contact pressure of the material to be treated on the elements is determined by its own mass, the profile or the crown of the bearing surfaces and the bearing radius R 1 of the element. In order to constantly displace the bearing surfaces or points of the material to be treated on the element circumference, this is e.g. formed in the form of a thread or offset in the direction of rotation, overlapping circular cutouts.

To transport the material to be treated from one point of support to the other, i. from power stroke to power stroke, each serves a one-way effective form of mating between the rotating element and items to be treated in a recess on the circumference of the element. This preferably occupies about 50 of the circumference of the element and is designed so that seen in the transport direction an outer radius R 3 (about 0.9 x R A-) in an inner radius R 5 (about 0.6 χ R 4) and after a straight piece a larger outer radius R 6 (about 2.6 χ R 4) follows and that its maximum depth is R * 8 (about 1.2 χ R 4).

After the material to be treated has been displaced by the reversing movement of the axes by 180 preferably for a corresponding time on a working cycle in local rolling motion, there is an additional movement of the axes and thus the elements by a single extension of the reversing angle to about 285th

The material to be treated is fixed or taken along during the additional forward movement at the lowest point of the recess and, shortly before the reversal of the movement process, rolls gently out of the recess into the next working cycle. During the additional backward movement, the material to be treated rolls over the recess. of the following element also gently and is then fixed again in the "prism" between the two elements or set in rotation by the normal Reversierbev / egung by 18O.
