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.

Abstract: A device and method for regulating pressure in a flock feed include a storage device disposed for receipt of fiber flocks, an exhaust air fan having a drive, and a controller in communication with the drive. A filling level measurement device and a pressure measurement device are provided in the storage device. The controller is configured to regulate the drive to achieve a target pressure as sensed by the pressure measurement device that is based on a filling level of the fiber flocks determined by the filling level measurement device.

Abstract: A system and corresponding method are provided for controlling production in a blow room, the blow room including a controller, a supplying machine having a supplying part, and a machine to be supplied that has a filling level measurement. The supplying machine and the machine to be supplied are connected to the controller. A production area is defined for the supplying machine and includes a minimum production and a maximum production. Production of the supplying part of the supplying machine is determined based on a filling level of the filling level measurement. When production of the production area drops below the minimum production, the supplying part of the supplying machine is shut down, the shutdown taking place independently of the filling level of the machine to be supplied.

Abstract: A process for calibrating the loading force of a breaker element of a bale opener on a bale group includes: (a) setting a force sensor used to measure the loading force at no load; (b) lowering the breaker element onto the bale group until reaching a loading force that is at least twice as high as an upper loading force at which the breaker element receives a lift command during normal breaking operation; (c) relieving the load on the breaker element; (d) setting the loading force at a negative value which includes signal distortion influences; and (e) lowering the breaker element until the loading force measured by the load sensor reaches at least the level of the upper loading force.

Abstract: 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.

Abstract: The invention relates to a method for operating a bale opener (1) having a stripping element (3) and a safety device for protection against penetration into a hazardous zone of the stripping element (3), said safety device consisting of sensory safety means, wherein a monitoring region (13, 131, 132, 133) at the front beneath the stripping element is detected and wherein the stripping element (3) is mounted on a stripping tower (2). According to the invention the safety device is at least one two-dimensional laser scanner (12), on which at least one monitoring region (13, 131, 132, 133), which is adjustable and variable over time, is monitored. The invention also relates to a corresponding bale opener (1).

Abstract: The invention relates to a process for calibrating the loading force of a breaker element (3) of a bale opener (1) before the breaking process of a bale group (4) and on a corresponding bale opener (1). In doing so, the breaker element (3) is calibrated so as to exclude any signal distortion influences and to ensure a stable and reliable scanning of the bale groups (4) by measuring the loading force. During the longitudinal movement of the breaker element (3) along the bale group (4), the force is measured continuously with the calibrated force sensor (12) and there is a lowering movement of the breaker element (3) when a lower loading force is reached, and there is an upward lifting movement when an upper loading force is reached.
