Definitions
- the present invention relates to a method and a device for winding a thread onto a bobbin.
- Such winding devices are used in textile machines of various types, for example end spinning machines, rewinding machines or dishwashers.
- the bobbin and the bobbin case are rotatably supported between two holding arms.
- the two holding arms in turn are held in a common swivel arm with a swivel axis.
- the bobbin tube rests on a support roller and is set in rotation via a drive, as a result of which a thread or yarn fed between the support roller and the bobbin tube is wound onto the bobbin tube and a bobbin is formed.
- the bobbin tubes can be designed with or without side flanges.
- the thread is moved back and forth with a traverse along a longitudinal axis of the bobbin tube, whereby different types of windings are formed in structure and shape.
- the bobbin tube is driven directly via a motor which sets at least one of the tube receptacles in rotation or indirectly via a friction roller arranged parallel to the bobbin tube.
- the distribution roller also serves as a back-up roller.
- the distribution roller can be designed as a so-called grooved drum.
- the grooved drum is provided with a yarn guide which is guided in slots by the rotation of the grooved drum in such a way that the thread is moved back and forth.
- the traversing of the thread is to be provided by a separate laying unit and the bobbin tube is to be supported by a separate support roller.
- the thread is clamped between the support roller and the bobbin tube or the thread already on the bobbin tube and is thereby deposited on the bobbin tube.
- the thread running into the clamp runs through a thread brake beforehand, which causes the thread running onto the bobbin to have a constant thread tension applied to it.
- Winding devices are known from the prior art which are equipped with a swivel drive for this movement. It is also known that swivel drives can be equipped with an angle measurement, so that a corresponding control always knows in which position the swivel drive is.
- WO 2019/00729 A1 also discloses a winding device in which the contact force is measured and regulated by moving the swivel drive of the swivel arms. After the winding process has ended, the finished bobbin must be lifted off the support roller or the friction roller in order to be able to remove the bobbin from the holding arms and insert a new bobbin tube. This lifting of the bobbin is brought about by a swiveling process of the swivel arm.
- the disadvantage of the known versions of the winding devices is that a quality feature that is decisive for further processing, consisting of the diameter and weight of a bobbin, cannot be determined by the winding devices themselves and therefore has to be determined manually after the winding process.
- the weight and diameter of the bobbin are important in further processing, for example, to the effect that several bobbins are used simultaneously on a machine in further processes and it must be ensured that several threads or games can be unwound from the bobbins in the same way and also have the same length.
- Gam is also regularly used in Units of importance are traded, which means that knowing the weight of the spool is also of economic importance.
- the object of the present invention is therefore to propose a method and a device for winding a thread onto a bobbin, which enables bobbins to be produced with predetermined properties.
- Another object of the invention is to provide a method which enables the winding process to be regulated while taking into account certain qualitative specifications, such as the density of a bobbin.
- an empty bobbin case is inserted and the bobbin case is rotatably held between two holding arms, each with a receptacle, and the two holding arms are held non-rotatably on a common swivel arm provided with a swivel drive, at least one of the holding arms being made in two parts and the two parts are connected via a load cell and the swivel drive has an angle measurement.
- a bending force acting on the holding arm is measured, the bending force being regulated by a swivel movement of the swivel arm in a predetermined range by the control system and a diameter by an evaluation device provided in the control of the winding device and a diameter after lifting the bobbin a weight of the bobbin can be calculated by the support roller.
- a magnitude of the bending force is determined.
- the bending force, which acts on the load cell in one of the holding arms of the swivel arm is determined by the weight of the bobbin and the contact pressure of the bobbin on the support roller, which is exerted by the swivel arm or the swivel drive assigned to it.
- the holding arm on the coil side of the bending force measurement is pushed away from the support roller and at the same time held in its angular position by the pivot drive on the opposite side of the holding arm or at least prevented from pivoting.
- the intended control compares the measured actual size of the bending force and corrects the angular position of the swivel arm by pivoting the swivel arm so that the measured actual size of the bending force corresponds to a specified target size of the bending force. This ensures that the thread is always placed on the bobbin with the same contact pressure over an entire winding cycle.
- the current diameter of the bobbin is known at all times in the event of a fault in bobbin operation, so that before resumption of operation, based on the diameter, it can be decided whether flushing should continue with the existing bobbin or whether the bobbin should be replaced with an empty bobbin case is advantageous. It is also advantageous if the bending force and the diameter of the bobbin are recorded by the evaluation device during the winding process. The recording of the values over the winding cycle is important for further processing of the wound thread or game. Subsequent processes can thus be matched to the known features, such as, for example, the unwinding speed in a subsequent game-processing process. The quality of the individual bobbins can also be individually verified through the recording. The possibility of determining the weight of the bobbin with the help of the bending force measurement enables the bobbin to be lifted briefly from the support roller and the current weight of the bobbin measured in the event of an interruption in operation, for example.
- the angle measurement and the bending force measurement are calibrated.
- different bobbin tubes can be used which differ in their weight and dimensions.
- the control has an input field via which the operator can determine a type of bobbin case. The basic data for force measurement and angle measurement are stored in the control accordingly.
- the control it is also conceivable for the control to recognize the bobbin case or for the bobbin case to be given data which is recorded and processed by the control system.
- the bobbin is lifted off the support roller and a final weight of the bobbin is measured.
- the bending force is measured with the aid of the swivel drive. It depends on the angular position of the swivel arm the weight of the bobbin is calculated from the bending force measurement using trigonometric calculations. This enables the weight of the bobbin to be determined in any angular position of the swivel arm, for example even if the swivel arm is swiveled into a position of the winding device opposite the support roller in order to remove or deposit the bobbin.
- a thread tension is measured in front of the winding device.
- Thread tension measurements are known from the prior art and are often combined with a control to keep the thread tension constant.
- EP 1 318097 A1 discloses a method and a device for regulating the thread tension and thus the thread tension.
- the thread tension can be kept constant by mechanical means as well as with the aid of actuators in that the thread entering between the support roller and the bobbin is more or less braked beforehand.
- a coil is characterized by its density.
- the density indicates how tightly packed a bobbin was wound up and depends on the thread tension and the clamping force which is exerted on the incoming thread by the bobbin in cooperation with the support roller.
- the density of the bobbin is preferably determined from the thread tension and the bending force during the winding process. By measuring the thread tension, operational fluctuations in the thread tension control are recorded and a real determination of the density over the course of a winding cycle is possible.
- the thread tension to be provided during a winding cycle is generally dependent on the material, quality and thickness of the thread or yarn to be wound up.
- a quality index is preferably entered into the control, which determines a tolerance range of the density of the coil.
- the quality achieved by a bobbin is measured by the fluctuations in density with which the bobbin was created. If the quality is high, only a slight fluctuation in density is permitted over the entire winding process. If a very high quality index is specified, it is possible that, due to the low permissible tolerance range of the density of the bobbin, a correspondingly precise control of the bending force and thus a lower bobbin speed will result. If, on the other hand, a larger tolerance range is accepted, the coils can be manufactured more quickly.
- the bending force is preferably regulated during a winding trip at a constant thread tension on the basis of a specified setpoint density of the bobbin within the tolerance range. This procedure makes it possible to manufacture coils which exactly meet the requirements for size and weight as well as the necessary quality for further processing.
- the final weight of the bobbin or a density profile over the winding process of the bobbin is output by the control or given to the bobbin.
- the data can be output in a memory which, for example, can be associated with the corresponding coil via an identification. Alternatively, a data record of the bobbin is given when it is removed from the winding device.
- the data can be printed on the spool or written into a chip attached to the spool. Corresponding color coding of the finished spool according to the various quality classes is also possible.
- the corresponding information can also be printed on a label that is stuck onto the spool.
- a winding device for winding a thread onto a bobbin tube, the winding device having a control, a swivel arm with a swivel axis, a swivel drive with an angle measurement for moving the swivel arm around the swivel axis, two rotatably arranged on the swivel arm and at a distance parallel to each other holding arms, each having a rotatably arranged at the end of the holding arms facing away from the swivel arm for the bobbin tube and a support roller for supporting the bobbin tube.
- at least one of the holding arms is designed in two parts and the two parts are connected via a load cell.
- the load cell is a bending beam load cell for measuring a bending force acting on the holding arm.
- An evaluation device in the control system provides for a calculation of a diameter of the bobbin and, after the bobbin has been lifted off the support roller, a weight of the bobbin.
- the load cell can be designed, for example, as a load cell or load cell; various types of so-called load cells can be used.
- force transducers is known in which the force acts on an elastic spring body and deforms it. The deformation of the spring body is converted into an electrical change via strain gauges, the electrical resistance of which changes with the expansion
- the electrical voltage and thus the change in strain are recorded via a measuring amplifier. This can be converted into a force measurement value due to the elastic properties of the spring body. Bending bars, ring torsion springs or other designs are used as the spring body. Piezoceramic elements are used in a further type of load cell. The directional deformation of a piezoelectric material creates microscopic dipoles within the elementary cells of the piezoelectric crystal. The summation of the associated electrical field in all unit cells of the crystal leads to a macroscopically measurable electrical voltage, which can be converted into a force measurement value. Load cells are known from the prior art and are now widely used in force and weight measurement. The load cell is preferably a bending beam load cell.
- the two parts of the holding arm are each attached to the bending beam load cell, whereby the bending beam load cell becomes part of the holding arm.
- a measurement of a thread tension is advantageously provided in front of the winding device.
- the combination of the above-described measuring device with a thread tension measurement makes it possible to determine the density of the bobbin.
- a specification of a quality index for determining a range of regulation of the bending force is preferably provided in the control.
- the quality of a coil is determined by its evenness. If the bending force is regulated in a narrow range or with a low tolerance, the result is a coil of higher quality.
- an input device is provided on the control, by means of which an operator can set the desired quality level for the subsequent flushing.
- the winding device has a writing device for transmitting data to the bobbin or the bobbin case, the transmission being provided by printing or electronic transmission.
- the data In order to make the data obtained on the properties and quality of the manufactured coil usable for subsequent processes, these must be given to the coil. Also with regard to the fact that the further processing of the bobbin is carried out in another factory or by another company.
- the data can also be applied to the reels or the reel sleeves in the form of codes (for example barcodes or QR codes).
- An alternative is to transfer the information to a memory chip (for example an RFID chip) built into the coil or the coil sleeve.
