Description

TECHNICAL FIELD

[0001] The utility model relates to a drive unit for a false twist spindle device (hereinafter referred to as spindle device) in a single drive texturing machine, wherein each individual spindle device is driven by an individual drive unit. BACKGROUND

[0002] Spindle devices for texturing synthetic yarns are known from the applications DE 10 2005 002 392.8 A1, DE 10 2008 033 646.7, DE 10 2009 033 312.6, DE 10 2010 034 460.5, DE 10 2019 004 302.2 and DE 10 2019 008 783.6. In such devices, so-called false twist is introduced into the synthetic thread by the disc-shaped friction elements of the device. Here, the aim is to increase the overall volume and / or the elastic elongation of the ejected smooth yarn and to make the twist in the yarn as uniform as possible. In order to achieve this at all 240 or more locations in the texturing machine, it is absolutely necessary that all devices are operated precisely at the same speed and rotational speed, also depending on the varying thread tension in the spun synthetic material presented.

[0003] The highest possible precision is currently achieved with the devices according to DE 10 2010 034 460.5, DE 10 2019 004 302.2 and DE 10 2019 008 783.6, in which all 240 or more devices can be operated according to varying thread tension with a rotational speed deviation of more than 0.2% in a texturing machine with simultaneous correction of the rotational speed.

[0004] The most common application on the market is the application in which the spindle devices are driven by asynchronous or synchronous motors via toothed belts and additional toothed belts ensure the synchronous operation of the spindle devices. In this application, a spindle device lower part is required in order to enable the semi-automatic connection of the pinion gear mounted additionally on one of the spindles of the spindle device with the toothed belt from the pinion gear of the drive motor. SUMMARY

[0005] The task of the utility model is, on the spindle device lower part available to date, which is equipped with an individual asynchronous or synchronous motor and from which the electronic control and voltage conversion for the motor are branched off at one location in the texturing machine, not only to equip this with a unique motor with pulley, but to install only a unique drive unit consisting of a DC motor, an electronic control circuit board and a transformer unit. The drive toothed belt and the additional toothed belts for synchronizing the three spindles and the spindle device itself remain unchanged.

[0006] The task is solved by replacing the hitherto synchronous or asynchronous motor by a drive unit consisting of a DC motor, a PCB motor control and a transformer unit, which reduces the input voltage provided from the texturing machine to 48 V or another necessary voltage. The present solution uses the hitherto spindle device lower part and also requires two toothed belts to drive the three spindles in the spindle device and to synchronize them.

[0007] In the drive unit for a false twist spindle device in a single drive texturing machine according to the present utility model, the drive unit comprises an integrated DC motor, an integrated PCB motor control therein and an integrated transformer therein, the PCB motor control controls the rotational speed of the spindle device, and the transformer transforms the input voltage provided from the texturing machine to the voltage required for driving the DC motor.

[0008] In the drive unit for a false twist spindle device in a single drive texturing machine according to the present utility model, the drive unit can be mounted to the existing spindle device lower part of the texturing machine, replacing the asynchronous or synchronous motor, to drive the spindle device at the desired rotational speed, and in this way to reduce the energy consumption of the single drive of the spindle device by more than 30% by using a DC motor.

[0009] Preferably, the line tension of the texturing line is controlled by an existing line tension monitor in the texturing machine, which can be connected to the PCB control of the drive unit, and in this way the final product is produced on the texturing machine such that the different line tension values at each location are optimized with the change in the rotational speed of the spindle device, so that there are virtually no more quality differences between the locations of the texturing machine and the final product no longer has to be sorted and packaged in sections.

[0010] The present utility model is also particularly suitable for retrofitting existing texturing machines with single drive for energy saving. BRIEF DESCRIPTION OF DRAWINGS

[0011] Figure 1 A schematic diagram is shown according to one embodiment of the present utility model, in which the hitherto used asynchronous or synchronous motor has been replaced by a drive unit comprising an integrated DC motor, an integrated PCB control and an integrated transformer. All other components of the spindle device lower part remain unchanged. In Figure 1 The lower part shows a schematic diagram of the unchanged drive by toothed belts. DETAILED DESCRIPTION

[0012] Figure 1 The spindle device lower part 1 is shown together with the installed spindle device 2 and the installed drive unit 4, in which the DC drive motor, the PCB motor control and the transformer unit are integrated.

[0013] In order to connect the DC motor in the drive unit to the PCB motor control and transformer unit, no connection cables are needed outside the drive unit 4, only a plug cable for providing the necessary energy for the drive and a control cable to the computer of the machine. One of the spindles 3 of the spindle device 2 is driven via pinion 7 and second toothed belt 6, and the first toothed belt 5 synchronizes all three spindles of the spindle device 2.
