Description
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 plurality of power supplies for supplying the at least one consumer with electrical energy, wherein the power supplies are designed such that each supplies at least a part of the workstations with electrical energy independently of one another and are connected in parallel on the output side for the common supply of the consumers.
Background
A number of design solutions for textile machines of the type mentioned in the introduction are known from the prior art. Thus, DE102015014177a1 has shown a textile machine with a plurality of side-by-side stations, each station having a plurality of power consumers, which are, for example, electric drives for winding shafts, thread traversing devices and sensors.
In order to supply the consumers of the workstations with electrical energy, the textile machine has a power supply unit with a plurality of power supplies, the outputs of which are connected in parallel in order to jointly supply the consumers of the workstations with electrical energy. By means of a supply unit which is connected on the input side to the supply network, the magnitude or frequency of the voltage or current supplied by the supply network can be adjusted as required, so that the consumers at the various stations can be operated at the required supply voltage. The parallel connection of several power sources of the power supply unit on the output side allows the power consumers of the workstations to be supplied as required, wherein the energy fed back by one or more power consumers of the workstation can also be distributed to the power consumers of another workstation by the parallel connection.
However, known textile machines of the type mentioned in the introduction have the disadvantage that the power supply unit for supplying these workstations is only inadequately monitored, so that a complete shutdown of the textile machine and a consequent production stoppage occurs in the event of a failure of one or more power supplies.
Disclosure of Invention
In view of this, the invention is based on the object of providing a textile machine which has a high level of failsafety.
The invention accomplishes this task by means of a textile machine.
The textile machine according to the invention is characterized in that the power supply of the power supply unit is designed to detect and transmit its power data and/or operating temperature to the control unit. The power data here refer in particular to the power consumption of the individual power supplies, wherein the power data are not only detected intermittently, but also continuously and transmitted to the control unit.
The possibility for detecting the power data and the operating temperature of these individual power supplies allows the operation of the textile machine to be controlled by the control unit when the power supply allows power or its temperature to be exceeded, in such a way that the load on the power supply is reduced, so that a stoppage of the textile machine due to a failure of the power supply unit can be prevented. The detection of the power data and/or the operating temperature of the power supply allows appropriate measures to be taken by the control unit in advance of an imminent disturbance in order to maintain the operation of the textile machine (or with a reduced power) in a stable manner, thereby effectively preventing the textile machine from completely stopping production. The power data and/or the operating temperature of the power supply are reliable indicators of the long-term operability of the power supply and therefore allow a very reliable monitoring of the supply of power to workstations of a textile machine overall.
The processing of the power data and/or the operating temperature of the power supply unit by means of the control unit can in this case take place in principle in any way, wherein the control commands of the control unit resulting from the respective power data and/or operating temperature can in principle be freely selected. A particularly advantageous embodiment of the invention provides, however, that the control unit is designed such that it reduces its energy consumption by changing the operating parameters of one or more work stations when the operating temperature and/or the power consumption of one or more power supplies exceeds a predetermined first threshold value.
According to a further embodiment of the invention, the control unit stores a first threshold value for the power consumption and/or the operating temperature, wherein, when the power supply or power supplies are above the first threshold value, a change of the operating parameters of the workstation or workstations is carried out by the control unit in order to reduce the power consumption thereof in order to avoid a disturbance of the power supply of the workstation, whereby the load on the power supply unit is reduced. In this case, the control unit makes it possible to adapt the power consumption of the consumer to the power supplied by the power supply, so that operating states which endanger the power supply of the power supply unit and lead to malfunctions of the textile machine are effectively avoided. In this case, by means of a freely selectable number of work stations, the energy consumption of which is reduced by changing the operating parameters, it is possible to reliably ensure that harmful operating states are avoided. As a first threshold value, for example, a defined operating temperature or a power consumption of the individual power supplies can be stored in the control unit, which should not be exceeded in principle (temperature) and/or for a defined period of time (power consumption).
In a further embodiment of the invention, the control unit is designed to shut down the supply of electrical energy to a part of the workstations if the operating temperature and/or the power consumption of the one or more power supplies exceeds a predetermined second threshold value. This embodiment of the invention reliably ensures that the operating state of the power supply is prevented from being endangered after the entire power consumption of the power supply unit has been effectively reduced as a result of the complete switching off of the electrical energy supply to a part of the workstations and the operating state of the power supply unit has thus been improved.
The design of the control unit according to this development of the invention is then preferably provided as a supplement to the design of the control unit which is advantageously set such that, above the first threshold value, a change in the operating parameters of one or more work stations is carried out in order to reduce the energy consumption thereof. In this preferred embodiment, the control unit therefore has a two-stage safety system for ensuring the operation of the textile machine. If the first threshold value is exceeded, a reduction of the energy consumption of the plurality of workstations takes place first, in order to obtain therefrom the power data and/or the reduction of the operating temperature to less than the first threshold value. If this does not bring about the desired effect, perhaps also because of a change in the operating parameters of the other work stations, according to this refinement of the invention, a further pressure relief of the power supply unit can be achieved in the second stage by shutting down the power supply to a part of the work stations stored in the control unit, in order thereby to reduce their power data and/or operating temperature below a first threshold value preset for reliable operation. With this embodiment of the invention, a complete stoppage of the textile machine due to a failure of the power supply unit can be avoided in a particularly advantageous manner.
Increasing the station energy consumption as a result of the operating temperature and/or the power consumption being below the first threshold value after the previously performed energy consumption reduction can in principle be done in any way, for example by an operator. An advantageous embodiment of the invention provides, however, that the control unit is designed such that, after the operating temperature and/or the power consumption has risen above a predetermined first threshold value and subsequently the operating temperature and/or the power consumption has fallen below a predetermined third threshold value, the energy consumption of the one or more workstations is increased by changing the operating parameters.
According to this embodiment of the invention, the control unit is designed to automatically increase the power supply to the workstations (whose power supply was previously reduced above the first threshold value) again in order to thereby operate the textile machine again at a higher power. The third threshold value is in this case lower than the first threshold value, so that a change of the operating parameters of one or more workstations is carried out in order to reduce the energy consumption and a renewed change of the operating parameters to the values which existed before the reduction of the energy consumption is carried out in a delayed manner, whereby a permanent change of the switching state in the case of the single first threshold value is effectively prevented.
In a further embodiment of the invention, the control unit is designed to supply electrical energy to a part of the workstations which are shut down after the operating temperature and/or the power consumption has risen above a predetermined second threshold value and subsequently has fallen below a predetermined fourth threshold value.
According to this embodiment of the invention, the control unit automatically performs a renewed supply of power to the workstations which were disconnected from the power supply by exceeding the second threshold value after a fourth threshold value which is lower than the second threshold value which is important for the shutdown of the power supply in order to guarantee the hysteresis function. The control unit design according to the overall development of the invention ensures in particular that the textile machine is automatically operated in the set state before the power reduction by the control unit after a lower operating state of the power supply unit which is important for operation, so that the textile machine is operated only at reduced power in the event of an imminent power supply unit failure.
The threshold value can in principle be selected in any way, wherein the operating parameters predetermined by the manufacturer for the interference-free operation of the power supply are preferably taken into account as frame conditions. The operating temperatures for the first and second threshold values should preferably be lower than the operating temperature preset by the manufacturer for the power shutdown. With regard to the power data to be used as the threshold, monitoring of power consumption over a prescribed time is particularly applicable. If the power consumption should therefore be greater than the value preset by the prescribed power consumption, measures for reducing the power consumption and the temperature of the power supply unit power supply can be taken by the control unit. In this case, according to a particularly advantageous embodiment of the invention, it is provided that the threshold value and/or the station proportion which should not be supplied with power above the second threshold value is adjustable. This design of the invention allows the operator of the textile machine to adjust the threshold value as a function of the operating conditions, in order to thereby ensure optimum textile machine operation.
In principle, the ratio of workstations to be shut down above the second threshold value can be freely selected, wherein a considerable portion of the workstations should no longer be supplied with power above the second threshold value in order to avoid a complete stoppage of the power supply unit and a complete stoppage of the textile machine. In this case, according to a particularly advantageous embodiment of the invention, it is provided that the proportion of workstations to be shut down above the second threshold value is 5% to 25%, preferably 10% to 20%, particularly preferably 15%. The occupation of the service station to be shut down ensures very reliable protection against damage to the load of the power supply unit.

Detailed Description
Fig. 1 shows a schematic view of a textile machine 1 according to the invention. The textile machine 1 comprises a plurality of side-by-side stations 2. The station 2 can be designed, for example, in a manner known per se into a winding position. Fig. 1 shows only one consumer 3 per workstation 2 by way of example. The power consumer 3 is preferably designed as an electric drive. The textile machine 1 is provided with a Direct-voltage rail 9 along the machine length. The consumers 3 and perhaps other consumers of the workstation 2, not shown, are connected to the dc voltage rail in order to supply electrical energy.
Distributed over the length of the textile machine 1 are a plurality of, in the present exemplary embodiment three, power supplies 4, which together form a power supply unit of the textile machine 1. The power supply 4 is designed in the embodiment shown as a rectifier with a post-dc voltage intermediate circuit. The input terminals 4.1 of the power supply 4 are each connected to an ac power supply network 8. The output terminals 4.2 of the power supply 4 are connected to dc voltage rails 9, respectively. These power supplies 4 are therefore connected in parallel at the output 4.2 and together supply the consumers 3 of the stations 2.
Textile machine 1 has a central control unit 6, which is connected via a data bus 5 to the not shown station controllers of stations 2 and to power supply 4.
The station controller allows individual operation of station 2. By means of the central control unit 6, different operating parameters can be set for each work station 2. Furthermore, the power supplies 4 are connected to each other and to the central control unit 6 by means of a data bus 5, so that the power supplies 4 permanently transmit their power data as well as the operating temperature to the control unit 6.
When the load on a power supply 4 is too high, this can be recognized by a first threshold value stored in the control unit 6, for example an operating temperature of 85 ℃ or too high a power consumption, for example greater than 7.5kw for more than 20 seconds, by means of the control unit 6, a number of previously determined operating parameters of the workstation 2 being changed in such a way that their power consumption and thus the load on the power supply 4 are reduced.
If the power has previously been reduced above the first threshold value, the power consumption can be increased again by the control unit 6 after the third threshold value has been undershot, wherein for this purpose the operating parameters of the workstation 2, for which the previous energy consumption has been reduced, are correspondingly adjusted.
Via the data bus 5 the control unit 6 is informed of the onset of the change of the operating parameter. If a change in the operating parameters should not lead to a desired relief of the power supply, a number of stations, for example 15%, can be shut down, i.e. disconnected from the power supply, by the control unit 6 above a second threshold value, which is greater than the first threshold value.
Similarly, when the power data and/or the operating temperature of the power source 4 have fallen below a fourth threshold value, which is lower than the second threshold value, the control unit 6 switches on again the station 2 previously switched off by being above the second threshold value.
As a second threshold value causing a part of the shutdown of the station 2, for example, a temperature of 85 ℃ of the power source 4 and a power consumption higher than 7.5kW for more than 20 seconds can be used. As a fourth threshold value for the renewed switching on of the shut-down station, for example, a supply temperature of 75 ℃ and/or a power consumption of less than 6.5 kw for more than 40 seconds can then be used.
The threshold value can be freely selected by the operator at the control unit 6.
Fig. 2 shows a second embodiment of the textile machine 1, which essentially corresponds to the textile machine 1 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.
