Definitions
- the invention relates to a method and an apparatus for Manufacture of bobbins in a wild winding using a Winding device which has a friction roller driving a cheese contains and the means for continuous recording and evaluating the angular speeds of the friction roller and has a bobbin, by means of a yarn application an initially empty bobbin tube during a winding trip Cheese is formed.
- a method and a device of the type mentioned at the beginning are known for example from DE 42 39 579 A1. There are the detected angular velocities of friction roller and cheese are evaluated to identify so-called image zones and trigger image disturbance methods to image wrap prevent or diminish.
- the invention has for its object a method of type mentioned in such a way that a statement about the quality of the cheese produced can and possibly already during the winding process Interventions in the winding process can be made to improve the quality.
- This object is achieved in that the angular velocities be evaluated in such a way that the course of the actual values the size of the yarn order continuously during a winding process is determined.
- the yarn order for example as a yarn order per revolution the bobbin or as a yarn order per time is an essential parameter for the quality of the cheese, since it gives a particular statement about the Winding density of the package can be obtained. Is the yarn order largely uniform and constant during a winding cycle, so this is a statement about the winding density since then the winding density is largely uniform.
- a cheese with uniform winding density during further processing Advantages for example in dyeing and in particular when unwinding. It should be noted here that despite a compensation of the contact force with which the cheese lies on the friction roller during the winding process, and despite a thread tension control to a constant Value still get relatively high density fluctuations especially in areas of image zones. Due to the Information about the course of the yarn application also in the area The image zones can also be based on the quality of the close the applied image interference method.
- the actual values of the yarn order as a curve during the winding trip recorded over time or over the coil diameter will. This can happen, for example, in that this Curve is printed parallel to the winding process. It is also possible to save this curve and print it out later or to display on a monitor to the quality to judge a package.
- the actual values of the size of the yarn order in at least one Area of an image zone continuously compared with target values and adjusted to these setpoints.
- the string (10) runs via an adjustable and / or adjustable thread tensioner (16) to a thread guide eyelet (17) and then to Reverse thread (15) of the friction roller (14).
- the cheese (13) is held by means of bobbins (18), which engage in the coil sleeve (12) and with the coil sleeve (12) and thus rotate with the cheese (13).
- the coil plate (18) are rotatable in a coil frame (19) stored that the cheese (13) with a predetermined bearing force rests on the friction roller (14).
- a control and / or regulating device belongs to the winding device (20).
- the control and / or regulating device (20) gives the speed of a drive motor (21) of the friction roller (14) before. This happens, for example, via a Inverter (22) on the trained as an asynchronous motor Drive motor (21) is connected.
- the tax and / or Control device (20) also acts only schematically illustrated, adjustable thread tensioner (16), so that the thread tension is adjusted and in particular to a constant Value is adjusted with which the thread (10) the cheese (13) is wound up.
- the coil frame (19) is shown only schematically Device (23) provided with the tracking force is adjustable with which the cheese (13) on the friction roller (14) rests.
- the device (23) can work autonomously, i.e. automatically over the coil diameter for one ensure at least approximately constant tracking force.
- the device (23) of the control and / or Control device (20) is set, for example a constant tracking force is set.
- a bobbin (18) and the shaft (26) of the friction roller (14) are assigned to angle encoders (24, 25) which are connected to the Control and / or regulating device (20) are connected.
- the invention is based on the consideration that an immediate Indications of the winding density of the yarn application per turn the cheese (13) or the yarn application opro time unit. Takes on the size of the yarn order at constant winding conditions, this corresponds to immediately an increase in the winding density. Conversely, an increase in the yarn application per turn or Time of winding density decrease.
- the course of the Actual values of the size of the yarn application via a winding trip, i.e. winding a yarn (or thread) onto an initially empty bobbin tube (12) until a finished package is produced (13) is therefore an important parameter for a package.
- the present invention therefore provides a method and a device available through which the course of the Actual values of the yarn application continuously during the winding process is determined.
- the yarn application ( ⁇ ) then corresponds to half the change in diameter after one turn. However, this calculation does not a usable result since the yarn application ( ⁇ ) per coil revolution in relation to the coil diameter is extremely low. Due to the noise of the measured values the yarn application ( ⁇ ) cannot be determined in this way.
- FIG. 3 Since the method and the device according to the invention can be used in the same way for cylindrical cross-wound bobbins (13) and for conical cross-wound bobbins (13 '), a conical cross-wound bobbin (13') is shown in FIG. 3 in connection with a friction roller (14) indicated.
- the angle transmitters (24, 25) deliver the angular velocity ( ⁇ sp ) of the cheese (13) and the angular velocity ( ⁇ FW ) of the friction roller (14).
- the diameter (d sp ) is calculated in an evaluation device (27) according to equation (1). In the case of a conical cheese, this is the driven diameter.
- the number of revolutions is counted in a revolution counter (28) on the basis of the angular velocity ( ⁇ sp ) of the cheese (13).
- the values of the revolution counter (28) and the evaluation device (27) are input into the mathematical filter (29), for example a Kalman filter, which has been developed from equation (2a).
- This filter provides the actual values ( ⁇ i ) for the yarn application.
- the filter also supplies the coil diameter (d 0 ) according to the last calculation.
- the diameter (d sp ) is calculated in a subsequent evaluation device (30) according to equation (2a), the value of the revolution counter (28) also being entered.
- the values (d sp ) and ( ⁇ i ) obtained in the above manner can be evaluated in several directions.
- the measured diameter (d sp ) can be compared in a comparison device (31) with a maximum value (d spmax ) which, if d sp corresponds to d spmax, outputs a signal for ending the winding process of the cheese bobbin (13) which has just been produced.
- the values (d sp ) and ( ⁇ i ) are further fed to a device (32) for recording, for example a memory in which the course of the yarn application ( ⁇ ) over the diameter (d sp ) of the cheese (13) is recorded. If required, the values recorded in the memory (32) can be forwarded to a printer (33) and printed out there. They can also be forwarded to a screen (34) and displayed there.
- a device (32) for recording for example a memory in which the course of the yarn application ( ⁇ ) over the diameter (d sp ) of the cheese (13) is recorded.
- the values recorded in the memory (32) can be forwarded to a printer (33) and printed out there. They can also be forwarded to a screen (34) and displayed there.
- the actual value ( ⁇ i ) of the yarn application can also be forwarded to a comparison device (35) which compares the actual value ( ⁇ i ) with a target value ( ⁇ soll ). If the actual value ( ⁇ i ) falls below the target value ( ⁇ soll ), this is a sign that the cheese (13) is being wound with too high a winding density.
- the comparison device (35) can trigger an engagement signal which acts on the thread tensioner (16) and / or the inverter (22) of the drive motor (21) in order to partially open the thread tensioner (16) and / or reduce the speed of the drive motor (22) to reduce the thread tension.
- the signal from the comparison device (35) can be supplied to the device (23) simultaneously or alternatively in order to reduce the contact force of the cheese (13) on the friction roller (14) and thus also to reduce the winding density again.
- the desired value ( ⁇ desired) may precede given or determined during the winding process, in particular in the area outside of image zones in which the Garnsmoked ( ⁇ ) is relatively constant. Since an intervention in the winding process is required in most cases only in the area of image zones, and only in image zones with larger bobbin diameters, the comparison device (35) expediently only operates in the area of such image zones. For this purpose it is possible to evaluate the signals of the rotary angle sensors (24, 25) in order to recognize the area of an image zone, as is known for example from DE 42 39 579 A1.
