Machine for winding pairs of tubes parallel to an advancing direction and independent of each other

摘要

A machine for winding pairs of tubes which are parallel to an advancing direction (Y-Y) and independent of each other in the longitudinal direction (X-X) of rotation of a reel connected to the machine comprising an apparatus for feeding and guiding the pair of tubes, formed by: a suitable pulling device arranged upstream of the reel in the direction of advancing movement of the tubes and intended to feed the two tubes in the transverse direction (Y-Y) as far as the point of entry thereof onto the winding reel; a tube-guiding device which is arranged in-line and downstream of the pulling device in the direction of advancing movement of the tubes and the internal seat of which is able to contain the two tubes arranged alongside each other in the advancing direction (Y-Y) and guided in the radial direction (Z-Z).

主权项

1. A machine for winding pairs of tubes which are parallel in an advancing direction (Y-Y) and independent of each other in a longitudinal direction (X-X) of a rotation of a reel connected to the machine, the machine comprising:
an associated motor arranged upstream of the reel relative to the direction of advancing movement of said tubes; a pulling device comprising a pair of belts each endlessly wound onto an idle roller and onto a motor-driven roller, the pair of belts being rotationally driven by the associated motor, the pulling device being configured to feed said tubes in the transverse direction (Y-Y) as far as the point of entry thereof onto the winding reel; a tube-guiding device that is arranged in-line and downstream of the pulling device, relative to the direction of advancing movement of said tubes, the tube-guiding device including an internal seat that is able to contain said tubes arranged alongside each other in the advancing direction (Y-Y) and guided in the radial direction (Z-Z); an engaging device configured to grip free ends of said tubes when said tubes enter onto the reel and i) retain said ends during winding and ii) release said tubes once winding has been completed; and a computer configured to control, synchronize, and perform the movements of the different parts and the machining sequences, wherein the pair of belts are configured with concavities corresponding to the convexities of the tubes.
