Description

Textile machine
Technical Field
The invention relates to a textile machine having a plurality of workstations with at least one consumer, in particular an electric drive, and having a supply unit for supplying the at least one consumer with electrical energy, comprising at least two power sources, wherein the power sources are designed in such a way that each power source supplies electrical energy to a workstation independently of one another and is connected in parallel in order to jointly supply the consumer.
Background
A number of designs of textile machines of the type mentioned in the introduction have been disclosed from the prior art. Thus, for example, DE102015014177a1 describes a textile machine having a power supply unit consisting of a plurality of power supplies, by means of which some power-consuming users of the workstations are supplied with power as required.
In textile machine design, the power supply unit is designed accordingly taking into account the expected energy consumption, wherein a plurality of power supplies are provided in order to ensure the power supply in view of the expected energy requirement of the power supply unit.
Practice has shown that the theoretically determined energy requirement of the textile machine is usually higher than the actual energy requirement, or that the available energy cannot be used for a long time. This results in the power supply for the station power generally operating in an operating range in which the power supply has only low efficiency, which generally results in high operating costs for the textile machine.
Disclosure of Invention
Since textile machine energy consumption is becoming increasingly significant, the invention is based on the task of providing a textile machine which allows energy-efficient operation.
The invention accomplishes this task with a textile machine.
The textile machine according to the invention is characterized by a control unit which is designed to adjust the number of power supplies used for power supply as a function of energy consumption in order for the power supplies of the power supply unit to operate in an efficiency-optimized manner.
According to the invention, the control unit can select the number of power supplies required for the power supply depending on the actual energy consumption of the textile machine, wherein, in addition to the number of power supplies, the control unit is also preferably designed to specifically select the power supply used for the power supply. This allows the power supplies to be used to supply energy requirements to operate in their respective efficient operating ranges with high efficiency. In addition to the low energy consumption, the corresponding operation of the power supply also ensures a long service life of the power supply, as a result of which the textile machine according to the invention has a low failure rate and low downtime costs.
The control of the power supply unit, in particular the number of power supplies used for power supply, can in principle be carried out in any way by the control unit. In a very simple embodiment of the invention, however, it is provided that the number of power supplies used for supplying power is dependent on the energy consumption of the textile machine determined by the control unit, wherein for this purpose corresponding data are stored in the control unit which indicate the number of power supplies to be used as a function of the energy consumption.
However, according to a particularly advantageous embodiment of the invention, it is provided that the control unit is designed to store an efficiency curve of the power supplies and to select the number of power supplies used for supplying power using the efficiency curve. According to this refinement of the invention, the efficiency curves are stored in the control unit for each power supply of the power supply unit, from which the optimum operating range of the respective power supply can be determined. According to this development of the invention, the control unit is designed to select the power supplies used and the particular power supplies to be used in an optimum manner as a function of the energy consumption and taking into account the efficiency curves of the individual power supplies, so that the supply energy is adapted to the energy requirements of the textile machine in a very advantageous manner, thereby resulting in a very cost-effective operation of the textile machine.
The specific selection and number of power supplies used for the power supply can in principle be carried out only taking into account the power supply data stored in the control unit and the energy requirements, without requiring extensive communication with the power supplies for this purpose. However, according to a very advantageous embodiment of the invention, it is provided that the power supplies are designed to acquire and transmit their power data and/or operating temperature to the control unit.
The acquisition and transmission of power data and/or operating temperature of the control unit allows the selection and the number determination of the power sources used for the power supply to be carried out according to the data transmitted by the respective power sources. In this case, the operating temperature and also the power data are used to determine in real time which operating range or with which efficiency the respective power supply is operated, so that a very reliable selection and control of the power supply is possible, which is suitable for the textile machine to operate optimally for the respective energy consumption. The selection of the power supply by the control unit is advantageously carried out by taking into account not only the power data but also the determined operating temperature.
The data required for the operation of the power supply unit can be stored in the control unit, in particular the preferably set efficiency curves can in principle be stored in any way, for example by the user simply entering the data when setting up the textile machine or via a suitable data interface. By means of the respective input, the advantageously set efficiency curve can also be stored in the control unit afterwards. However, according to a very advantageous embodiment of the invention, it is provided that the control unit is designed to determine the efficiency curve.
By means of the development of the invention, in which different data of the power supplies are made available by the control unit during the operation of the textile machine, it is possible for the control unit, in particular taking into account the power data, to determine specific efficiency curves for the individual power supplies, which allow the textile machine to be operated in a very efficient manner by means of the control unit, and to determine the number and selection of the power supplies to be used for the power supply taking into account the very accurate data determined by means of the control unit for each power supply.

Detailed Description
Fig. 1 shows a schematic view of a textile machine 1 with two workstations 2 arranged next to one another. The station 2 can be designed, for example, as a winding station in a manner known per se. Fig. 1 shows only one consumer 3 at each work station 2 by way of example. The power consumer 3 is preferably designed as an electric drive.
Textile machine 1 has a direct-voltage bar 9 along the machine length, to which consumers 3 and possibly other consumers not shown in workstation 2 are connected for supplying electrical energy.
A plurality of, in the present exemplary embodiment three, power supplies 4 are provided over the length of the textile machine 1, which together form a power supply unit for the textile machine 1. The power supply 4 is designed in the exemplary embodiment shown as a rectifier with a downstream dc intermediate circuit. The input terminals 4.1 of the power supply 4 are each connected to an ac power supply network 8. The outputs 4.2 of the power supply 4 are each connected to a dc bus 9. The power supplies 4 are therefore connected in parallel at the output 4.2 and jointly supply the consumers 3 of the stations 2.
Textile machine 1 also has a central control unit 6, which is connected via a data bus 5 to the not shown position controllers of stations 2 and to power supply 4.
The interconnected power supplies 4 are connected to a central control unit 6 via a data bus 5, so that the power supplies 4 permanently transmit their power data and operating temperature to the control unit 6.
Based on the power data and the operating temperature, the control unit 6 determines for each power supply 4 an individual efficiency curve which allows the power supply unit to operate within an optimized operating range. To this end, the number and selection of power sources 4 to be used in the most efficient manner for the power supply of the stations 2 is determined by the control unit 6 depending on the energy requirements of the stations 2.
It is thus possible to provide a very efficient supply of power depending on the current energy demand of the textile machine 1, wherein the power supply 4 always operates in a range in which the power supply has a very high efficiency. The efficiency curve is determined here by the control unit 6 for each power supply 4 as a function of the determined efficiency data and the operating temperature.
Fig. 2 shows a further embodiment of a textile machine, which essentially corresponds to the textile machine of fig. 1. The only difference is that the power supply 4 is not distributed on the textile machine 1, but is mounted in the same switch cabinet 7 at the end of the textile machine 1.
