Abstract
A take-off arm is provided for a bale opener for taking off fiber flocks from fiber bales. The take-off arm includes a housing, and a take-off unit having an axial length within the housing. A pressing element is connected to the housing via only load cells such that a contact force (F) of the take-off arm on the fiber bales is continuously measured by an evaluation of the load cells situated between the pressing element and the housing.
Claims6
A take-off arm for a bale opener for taking off fiber flocks from fiber bales, the take-off arm configured to be controllably raised and lowered on the bale opener, comprising:
- a housing;
- a take-off unit having an axial length, the take-off unit comprising a detaching roller having take-off teeth;
- a pressing element connected to the housing via only load cells such that a contact force of the pressing element on the fiber bales is directly and continuously measured by the load cells, the pressing element comprising a grid configured with hold-down plates;
- wherein the grid is situated below the detaching roller, and the take-off teeth of the detaching roller engage with the fiber flocks through the grid;
- and
- wherein a height of the take-off arm on the bale opener is controlled based on the measured contact force.
