A textile machine producing take-up packages, comprising a storage area for wound take-up packages, a detecting element for measuring the weight of each take-up package to be placed on the tray, a summing element for adding up the measured weights of the take-up packages to be placed on the storage area, and an output element for outputting an output signal if the sum of the measured weights of the take-up packages exceeds a predefined threshold value.

A device for rewinding yarns from a feed bobbin onto a bobbin tube includes a controller, a machine frame, and a bobbin mandrel held in a rotationally fixed manner in the machine frame to receive the feed bobbin. A winding device includes a thread brake to set a yarn tension in the yarn rewound from the feed bobbin onto the bobbin tube. A holder for the bobbin mandrel includes a weighing system in communication with the controller, wherein an adjustment of the thread brake is provided by the controller based on a weighing of the feed bobbin.

A winding device for winding a yarn onto a package tube has a spindle that holds and rotationally drives the package tube. A support roller abuts against a peripheral surface of the yarn winding package during winding of the yarn. The spindle is supported by a pivotably mounted swivel arm so as to swivel relative to the support roller. A contact-force control device is provided and includes an actuator disposed to actuate the swivel arm, and a control device configured with the actuator. A bending beam load cell is configured on the swivel arm to determine an actual value of a contact force between the yarn package and the support roller. The contact force is regulated to a predetermined target value via control of the actuator by the control device.

A reel weight measurement system is shown and described herein. In some embodiments, the reel weight measurement system comprises strategically placed position and load sensors for measuring an orientation of a reel-carrying unit and measuring loads in the reel-carrying unit. The loads may be indicative of forces due to the weight of the reel when the reel is supported by a carriage of the reel-carrying unit. The weight of the reel may be determined by summing the forces and moments in the system while the carriage is in motion or static. Further, the weight of the reel may be determined by comparing the force measurements and orientation of the carriage to stored calibration data.

The invention relates to a winding device (16) for winding a yarn (20) onto a package tube (22) in order to form a yarn winding package (24). The winding device comprises a spindle (34) for holding and rotationally driving the package tube (22) about its longitudinal axis (30) and a support roller (40) that abuts against the peripheral surface of the yarn winding package (24) during winding of the yarn (20). The spindle (34) with the yarn winding package (24) can be swiveled relative to the support roller (40) by means of at least one pivotably mounted swivel arm (46). The winding device has a contact-force control device (54) with an actuator (56) for the swivel arm (46), with a control device (58) for controlling the actuator (56), and with a bending beam load cell (60) associated with the swivel arm (46). This is used to determine a respective actual value of the contact force F.sub.A of the yarn winding package (24) against the support roller (40) with which the contact force F.sub.A can be regulated to a predetermined target value by means of the control device (58) through appropriate controlling of the actuator (58). The invention further relates to a yarn processing machine (10) with an aforementioned winding device (16).

A device for processing threads or yarns of textile fibers includes a supporting structure for at least one spool for feeding a thread or a yarn of textile fibers and at least one textile machine, associated with a control panel, which uses the thread or yarn unwound from the at least one feeder spool. The device also includes a supporting structure for weighing the feeder spool, which is functionally connected to a control and actuation device. The weighing device is associated with protection elements adapted to avoid excessive stresses of the weighing device during the operations for loading and/or unloading the feeder spool onto and/or from the supporting structure.

Methods for determining that a consumable welding package has been, or may have been, replenished in a high production welding environment and that a tracked weight value of the consumable welding package should be reset. An operator of a welding system can be notified that a consumable welding package may have been replenished and, therefore, that the weight value of the consumable welding package may need to be reset in the welding system. Alternatively, the weight value of the consumable welding package in the welding system may be automatically reset when the welding system has determined that the consumable welding package has been replenished.

A textile machine producing take-up packages, comprising a storage area for wound take-up packages, a detecting element for measuring the weight of each take-up package to be placed on the tray, a summing element for adding up the measured weights of the take-up packages to be placed on the storage area, and an output element for outputting an output signal if the sum of the measured weights of the take-up packages exceeds a predefined threshold value.

A device that feeds an elongated workpiece to a forming machine includes a reeling unit with a frame and a reel carried by the frame and accommodates a workpiece supply formed as a coil of workpiece material. The reel is mounted rotatably about a reel axis relative to the frame. The device has a weight-distribution sensing device set up to sense a lateral distribution of a reel weight with respect to the reel axis, the reel weight representing a weight of the reel with or without an accommodated coil.

Provided is a yarn spindle coding method including: when determining that yarn spindles are fully wound, sleeving the yarn spindles in the winding machine sequentially outside a yarn connecting rod of a doffer, and updating the number of unloading times of the winding machine and recording first doffing time of each yarn spindle; generating a first information code of each yarn spindle based on identification information of the winding machine, the updated number of unloading times, the first doffing time and position information of each yarn spindle; and sending each first information code to the doffer, so that the doffer determines a corresponding target yarn spindle among the yarn spindles according to a matching degree between the first doffing time and second doffing time of each yarn spindle recorded by the doffer and code the information code on a corresponding target yarn spindle.
