Abstract
Official abstract text for this publication.
A bale opener for the take-off of fiber tufts from fiber bales includes a take-off tower, which is arranged on a horizontal drive or a rotating frame, and a take-off arm. The take-off arm is held on the take-off tower in a guide so as to be vertically adjustable. A single lifting spindle having a longitudinal axis in the movement direction of the take-off arm is provided for the vertical adjustment of the take-off tower. The lifting spindle is fastened on the take-off tower and the take-off arm is connected to the lifting spindle via a nut.
First claim
Opening claim text (preview).
The invention claimed is: 1. A bale opener for take-off of fiber tufts from fiber bales, comprising: a take-off tower arranged on a horizontal drive or a rotating frame; a take-off arm held on the take-off tower in a guide so as to be vertically adjustable along the take-off tower; a single lifting spindle fastened on the take-off tower for vertical adjustment of the take-off arm, the lifting spindle having a longitudinal axis in the movement direction of the take-off arm; the lifting spindle fastened on the take-off tower at an upper end of the lifting spindle, wherein a lower end of the lifting spindle is not held in the take-off tower; the take-off arm connected to the lifting spindle via a recirculating ball nut; and the nut provided with the drive and the lifting spindle held in a rotationally locked manner. 2. The bale opener according to claim 1 , wherein the take-off arm is engaged with the guide such that the lifting spindle is loaded with forces only in a direction of the longitudinal axis of the lifting spindle. 3. The bale opener according to claim 1 , wherein the guide comprises at least two mutually spaced guide rails fastened on the take-off tower in a direction of the longitudinal axis of the lifting spindle, the guide rails comprising opposite parallel legs and a closed end. 4. The bale opener according to claim 1 , wherein the lifting spindle is located on the take-off arm at a position to generate a predetermined tilt on the take-off arm. 5. The bale opener according to claim 1 , further comprising rollers or gliding elements installed on the take-off arm and engaged against the guide in the take-off tower to provide play-free guidance of the take-off arm. 6. The bale opener according to claim 1 , wherein the drive is a synchronous servo-motor. 7. The bale opener according to claim 6 , wherein the drive comprises sensors that determine the vertical position of the take-off arm and are used to perform a defined vertical adjustment of the take-off arm as a function of sensed revolutions of the nut. 8. The bale opener according to claim 1 , wherein the lifting spindle is fastened on the take-off tower via a load cell at an upper end of the lifting spindle. 9. The bale opener according to claim 1 , wherein the guide comprises at least two mutually spaced guide rails fastened on the take-off tower in a direction of the longitudinal axis of the lifting spindle, and a plurality of transverse and longitudinal combination rollers engaged against the guide rails, the guide rails comprising opposite parallel legs and a closed end.
