An electromechanical actuating drive () for a bulk-goods shut-off element, comprising an electric motor () and a control and drive electronics unit () associated with the electric motor (), wherein the electromechanical actuating drive () comprises a mechanism for storing energy.

Electromechanical actuator for a bulk-goods shut-off element

A dosing and weighing device () comprising a housing () having an inlet opening () and an outlet opening (), and a weighing surface (), which is operatively connected to at least one weight sensor (), a mechanism () for detecting a pressure difference between a pressure in the housing upstream and a pressure in the housing downstream of the weighing surface (). Via a control unit (), the detected pressure difference is used to correct the weight detected by the weight sensor ().

The apparatus () according to the invention for packing bulk material into a container () comprises a provisioning device () for the container (). The container () has a filling side with a filling opening arranged therein. The apparatus () further comprises a gripping device () for gripping of the substantially closed and empty container () by the provisioning device (). The apparatus optionally comprises a conveying device () for conveying the container () to a packing device (). The apparatus further optionally comprises a container-opening device () for opening the container (). The gripping device () has a detection device () for detecting the position of the container on and/or in the provisioning device (). The apparatus () additionally has a positioning device for positioning the container on the basis of said detected position.

Apparatus and method for packing bulk material into a container

The device () according to the invention for metering and in particular compressing bulk material () comprises a conveyor for metering the bulk material. The device () further comprises a measuring device for measuring a measuring variable and a receiving device () for receiving a container, in particular a bag (). The conveyor has an outlet () for the bulk material (). The container has a filling opening (). The receiving device () and the outlet () can be positioned relative to each other dependent on the measuring variable during the metering of the bulk material () into the filling opening (). In particular, the outlet () and the receiving device () can be positioned in a manner that can be controlled and/or regulated.

The invention relates to a yarn-tensioning device for producing a specific thread pull on a thread () that is unwound from a winding point () of a creel () and is guided to a warping machine arrangement (). Said yarn-tensioning device comprises a rotating body () which is at least partially wound round by threads and an electric motor () which is connected to the rotation body. Said motor () is equipped with at least one brake transistor () for discharging excess energy produced when the generator of the motor is operated, said brake transistor being able to convert generator energy, arising when the generator is operated, into heat.

Yarn-tensioning device and arrangement and method for operating a creel

The invention concerns a creel () comprising a plurality of winding heads () from which several yarns of the same type or of different types are drawn simultaneously by means of a winding machine (). Said creel comprises at least one dynamic yarn tension device () which is associated with each winding head and at which a variable braking force is applied to the yarn to produce a predetermined yarn tension. Each yarn tension device () can be activated by means of an associated drive motor (). Said creel () comprises a control device for controlling the yarn tension based on the angular speed or the yarn speed during a start-up and/or an interruption of the winding machine (), as well as a regulator () for regulating the yarn tension during the normal stationary phase of the winding machine (). The control device and the regulator () are designed such that the yarn tension or the output tension of each yarn can be maintained at a substantially constant level relative to a setpoint value. In order to determine a quantity of regulation () of the braking force required to control the yarn tension device (), a precompensation of the disturbing quantity is implemented. Said precompensation calculates from the yarn speed (v) as input quantity a compensated correction quantity () of at least the inertia of the motor and a friction coefficient of the drive motor ().
