Definitions
- the invention relates to a device for the continuous treatment of endless textile material, such as. B. fabric webs, with several rotatably mounted in a housing, connected in two rows one behind the other, partially individually electrically driven deflection rollers and an upstream and / or downstream, from a pneumatically or hydraulically via a pressure cylinder or electrically loaded with a predetermined pressure voltage control device, such as Dancer roller, pair of press rollers controlled at the speed of rotation for the transport of the textile goods.
- a predetermined pressure voltage control device such as Dancer roller, pair of press rollers controlled at the speed of rotation for the transport of the textile goods.
- a shrinking material web is also placed in a wet treatment device of the type mentioned, the textile material contracts more and more during the treatment, with a shrinkage curve characteristic of this textile material.
- This fact means that each deflecting roller following in the transport direction must rotate at a different speed than the previous one. It is true for such a treatment that no, or at least a uniform fabric tension is generated in the textile material over the entire working process. Otherwise the shrinking process would be adversely affected.
- the regulation of the speed of passage of the textile goods, d. H. the take-off speed is generally done by the known dancer roller control.
- the height of the dancer roll is used to feed the take-off unit, such as a pair of press rolls at the outlet of the machine, via a potentiometer, which ensures the desired passage of the goods.
- a special regulation of the power supply is referred to in DE-C-856 290.
- the invention has for its object to further develop a device of the type mentioned in such a way that the deflection rollers provided with a direct drive within the device are driven differentially, in comparison to the product tension prevailing there with the aim that at each deflection roller by actuation of a exactly the same torque, the additional longitudinal tensile forces that arise on the respective deflection rollers, as a result of a shrinking process occurring, the respectively changing coefficients of friction or the absorbed drag water, etc., are now canceled out again to the value “zero”.
- the invention provides that the electric drive is electrically connected to at least two of the deflecting rollers, each with a force measuring device, the measured values of which are compared in a differential amplifier and converted there into a positive or negative control signal for correcting the actual torque.
- a force measuring device the measured values of which are compared in a differential amplifier and converted there into a positive or negative control signal for correcting the actual torque.
- the first and last driven deflecting roller of this treatment device with the force measuring devices are provided.
- the weight of the dancer roller which determines the tension in the textile material due to its active weight and is also a deflection roller, is measured and used to adjust the torque of the deflection roller drives within the treatment device, or where more than just two , possibly all driven deflection rollers, are compared and controlled in terms of their drive value.
- the setpoint torque for driving the deflection rollers is expediently determined by the active weight of the dancer roller or the like.
- the invention is explained using an exemplary embodiment on a wet treatment device. It consists of a completely closed housing 1 with an inlet and outlet provided on the end faces, in which deflection rollers 2, 2 'are rotatably mounted in two rows for the meandering transport of a textile material 3.
- the deflection rollers 2 'of the lower row rotate within a liquid with a level 4. They are not driven, while the rollers 2 of the upper row are each individually electrically driven.
- a pair of squeeze rollers 5 is arranged, which exerts a certain longitudinal tension on the textile goods 3 for the uniform transport thereof.
- the transport speed, the speed of rotation of the press rolls 5 determines the dancer roll 6 arranged upstream of the device, which acts on the press roll drive via a potentiometer 7.
- the dancer roller 6 is pneumatically or hydraulically loaded by a pressure cylinder 8. However, it is also possible to arrange an electrical voltage regulating device here.
- the setpoint torque is fixed on the roller drives 10.
- This dancer roll is preceded by a further pair of press rolls 9, which basically can be assigned to the preceding machine parts, not shown, between which, however, the transport speed of the textile goods 3 is controlled by their respective direct current drive.
- the web tension S that is determined by the transport of the textile material through the treatment device from the press rolls 5, 9.
- this web tensile force S on the other side of the roller corresponds to the force S '.
- the frictional resistance W acts counter to the circumferential force and the roller weight G W acts vertically downwards.
- the deflecting rollers must be driven with a certain size of a torque.
- load cells M 1 and M 2 are used , by means of which the first and last deflection roller are supported on their bearing shaft in relation to the housing of the device.
- These electrical units measure the web tensile forces F N at the assigned deflecting rollers 2 and pass them on according to FIG. 3 to a differential amplifier, which converts them into a control signal: depending on the sign of the resulting signal used for torque control, the torque of the deflecting roller drives then changes.
- the optimum setting is achieved when the two load cells M 1 and M 2 are subjected to the same forces F N.
- the dancer roller 6 can also be used to adjust the torque on the last deflecting roller (M 2 ), since this is the desirable target torque due to its weight or due to the longitudinal tension it causes in the textile material pretends. M i can therefore be omitted and M 3 can work together with M 2 .
- the device is shown again in cross section in FIG. 4, with the upper driven deflecting roller 2 and the lower loose-rotating deflecting roller 2 '.
- the electric motor 10 drives the upper deflection roller 2, and the load cells M 1 and M 2 (or M 3 ), which are assigned to the respective shaft on the other longitudinal side of the device, are used for the longitudinal traction train which actually acts on this deflection roller.
