Description
Technical Field
The invention relates to a spinning preparation machine, in particular a flat card or roller card, having an inlet side for fiber bundles, which is fed by means of rollers to a rotating cylinder and disintegrates into individual fibers between a stationary carding element and a surrounding flat bar and cylinder, orients and cleans the resulting web, and conveys the web from the cylinder to a doffer, downstream of which at least one separating device is provided for further processing or storage of the web, comprising a machine control device which is at least configured for processing and adjusting production data.
Background
In textile technology, it is known to use sensors in spinning preparation machines (e.g. flat cards or roller cards) for processing cotton, chemical fibers or the like, for example, to monitor the temperature of the individual components, the carding gap, the drive or regulating motor and the throughput of the fibers. The sensor data are transmitted via electrical lines to the control device of the carding machine, are evaluated there and used for adjusting the carding machine, either by signaling the operator of the desired change in settings or automatically by the control or adjustment circuit. These electrical lines are led from various points of the carding machine to the switch cabinet, where they are fitted to the wiring board by means of plugs and from there are connected to the inputs and outputs of the control device. The switch cabinet is usually arranged on the rear side of the carding machine in the region of the feed shaft, so that a total of several hundred meters of electrical lines are available due to the number of sensors, adjusting devices and drive motors. Because some of these electrical conductors still forward signals in analog form, they must be shielded from the high frequency and high current carrying motor conductors. Furthermore, the control device must process more and more input/output signals at the same or shorter intervals. In the event of a system failure, it is very costly to check all the terminals, wires and connected sensors. The cost of laying these electrical conductors and shielding the high frequency currents is quite expensive.
Disclosure of Invention
Accordingly, the object of the present invention is to improve a spinning preparation machine in such a way that the costs for laying and shielding the electrical conductors are reduced and the costs for eliminating possible faults are reduced.
The device according to the invention is used in a spinning preparation machine, in particular in the form of a flat card or roller card, which has an inlet side for the fibre bundle, which is fed by means of rollers to a rotating cylinder, and which breaks down into individual fibres between a stationary carding element and a surrounding flat bar and cylinder, orients and cleans the fibre web produced thereby, and which conveys the fibre web from the cylinder to a doffer, at least one separating means being provided downstream thereof for further processing or storage of the fibre web, the spinning preparation machine comprising a machine control device which is at least configured for processing and adjusting production data.
The technical teaching of the invention is that the spinning preparation machine has at least one pre-control device which is designed to process the data of the sensors and/or drives independently of the machine control device and to control at least the drives connected to the pre-control device. In particular, locally arranged sensors and drives are connected to the pre-control device, so that they are simpler and less prone to interference. The sensors and drives associated with the individual components are referred to as being arranged locally, i.e. for example in the region of the components (cylinder, revolving cover, side plate) or at this region, or for example sensors or drives which are of great importance for a specific function (carding gap adjustment or pitch adjustment of the tin Lin Yudao-f or foreign-body or nep detection behind the doffer, etc.). Thus, a possible fault in the control can be determined simply, since the data communication between the pre-control device and the machine control device can be limited.
In an advantageous development of the invention, the at least one pre-control device is arranged on at least one side plate in the region of the cylinder. Thus, for example, data of a temperature sensor arranged on the side plate or in the area of the cylinder or at the area of the cylinder can be entered into the pre-control device. Preferably, the pre-control device can be arranged on the side plate in the region of the axis of rotation of the cylinder. A short wire length and a simple wiring are thereby also obtained.
Preferably, the at least one pre-control device can process all relevant data of the sensor and the drive for the comb gap adjustment. The pre-control device can thus be operated independently of the production data of the machine control device, which reduces the burden on the machine control device and enables the use of different processors, for example.
For this purpose, the at least one pre-control device may have at least one processor for processing data. The processor may be programmable independently of the machine control and may be combined with additional memory into an electronic assembly, for example. The modular subfunction can thereby be programmed into the spinning preparation machine and modified according to customer requirements, independently of the basic functions stored in the machine control device.
Advantageously, the pre-control device may communicate with the machine control device using a bus system. The bus system may be made of a cable that is not susceptible to disturbances, which is easy to lay.
Preferably, the pre-control means is programmable independently of the machine control means. Thereby, the software update for the sub-functions may be independent of the intervention of the machine control means.
In an advantageous embodiment, the spinning preparation machine can have at least two pre-control devices, wherein each pre-control device is designed to process data for one or more individual sensors and drives and to control the associated drive. For example, a separate pre-control device can be arranged on each side plate, which processes the temperature and carding gap data separately for each side of the spinning preparation machine.
The functional range can be designed for the adjustment of the carding gap for each side of the carding machine, or for the adjustment of the distance between at least two components, or for the quality characteristics of the fibrous web.
Preferably, the communication of the pre-control device with the machine control device may be limited to exchanging input nominal and actual values for production data and/or to fault or readiness reporting. The data processing from the individual sub-functions thereby takes place independently of one another and speeds up the efficiency of the spinning preparation machine.

figure 2 shows a perspective view of a side plate of the carding machine.
Detailed Description
Preferred embodiments of the spinning preparation machine and method according to the invention are described with reference to fig. 1 to 2. Like features in the drawings are provided with like reference numerals. It is to be understood that the figures are only shown simplified, in particular not to scale.
The spinning preparation machine may be a flat card K, which is shown in fig. 1 in a schematic simplified side view. Alternatively, the spinning preparation machine may also be configured as a roller carding machine, not shown. The fibre bundle is guided through the shaft to the feed roller 1, the feed plate 2 and via a plurality of licker-in rollers 3a,3b,3c to the cylinder 4 or drum. On the cylinder 4, the fibers of the fiber bundle are parallel and cleaned by means of stationary and encircling carding elements (cover bars) 14, which are arranged on a revolving cover 13 revolving around cover turning rollers 13a,13 b. The resulting web is then transported by doffer 5, stripping roller 6 and several squeeze rollers 7, 8 to a web guiding element 9, which converts the web into fiber strands by means of a collecting bell 10, which are transferred by separating rollers 11, 12 to a subsequent processing device or a strand drum 15 with a coiler 16. The center (or bearing axis) of cylinder 4 is marked with M. Arrow a indicates the machine direction of the fibrous material or web. The direction of rotation of the individual rollers is indicated in fig. 1 by arcuate arrows, wherein arrow 4b shows the direction of rotation of cylinder 4. The direction of rotation of the revolving cover 13 in the carding position is marked with C and the direction of return of the revolving cover is marked with D. The area of the flat card K where the sliver is discharged and stored in the can 15 is called the front side of the flat card K. At the rear side of the carding machine, i.e. in the region of the incoming fibre bundle, a switch cabinet 25 is usually provided. The machine control 26 of the flat card K can likewise be arranged in the switch cabinet 25 or in the region of the switch cabinet 25 and can communicate with an input display, not shown here, which can be arranged laterally in the region of the flat card K from which the sliver is discharged. The machine control device 26 may also be provided in a common housing with the input display.
All data which are important for the production of the card, such as the fibre bundle feed, the rotational speed of the drive motor, the quality control of the fibres to be processed, the air pressure prevailing, the can filling situation and all options of the wear-related components, are processed in the machine control 26 of the flat card K. The machine control device 26 can communicate with the central control device of the spinning preparation machine, so that the data of all the machines of the spinning preparation can be summarized there and quality control and presetting of the different types of machines can be carried out.
The at least one pre-control device 24 according to the invention is preferably arranged in the region of the cylinder 4, for example on the side plate 17 or in the region of the axis of rotation of the cylinder 4, since there is a central point of the collection of electrical conductors to the sensors and servos arranged on the cylinder 4 or around the cylinder. The data from the locally arranged sensors are intelligently preprocessed and summarized by the at least one preprocessing unit 24, so that the electrical lines are formed shorter and the susceptibility to interference is significantly reduced. The advantage is that the signal flowing into this is preprocessed independently of the machine control 26, so that the load on the machine control 26 is reduced. For this purpose, the pre-control device 24 may have electronic components (processor and memory) which are configured as hardware and with which the pre-processing of the signals of the sensors and servo drives can take place, or alternatively be configured as a high-performance processor which is configured by software. In particular, the pre-control device 24 is configured to process all the data related to the adjustment of the carding gap, for example various temperature signals of the different components of the machine, various contact signals of the cylinder 4 with the adjacent components (such as licker-in, carding and rejecting elements, circumferential cover strip 14 and/or doffer 5), counting signals of the revolving cover 13 and cylinder 4, and/or control signals and feedback for driving the adjustment wedge strip and thus the carding gap. The pre-control device 24 can be configured to continuously process the signal so that the comb gap can be adjusted independently of the machine control device 26.
The contact signal can be evaluated at high frequency in the pre-control device 24, for example, in order to calibrate and adjust the carding gap between the clothing of the rotating cover 13 and the clothing of the cylinder 4. Alternatively or additionally, contact of the elements with the cylinder 4 outside the revolving cover 13 can be detected and processed in the pre-control device 24. The adjustment circuit of the servo drive of the wedge bar ensures that the preselected comb gap is adjusted and remains constant. In this case, data from temperature sensors are additionally included, so that the carding nip can be kept constant as the temperature of the machine changes. Communication of the pre-control device 24 with the machine control device 26 may be limited to exchanging nominal and actual values for inputs, fault or readiness reports, and may be via a digital bus system. Such a bus system may be made of a cable with a plurality of wires that is not susceptible to interference. The local functional integration of the sensors enables the operator of the machine to be specifically relieved of faults and controlled without having to laboriously identify the relevant components in the switchgear. LEDs may be arranged on the digital bus node, which LEDs indicate the basic functions of the individual components and their functional readiness.
According to fig. 2, the pre-control device 24 is arranged on the side plate 17, for example in the region of the axis of rotation of the cylinder 4. The pre-control device 24 can also be arranged reasonably in another central position in the area of the cylinder 4. Data from the servo drives and sensors concerning the temperature of the side plates 17, the ambient temperature 18, the feed monitoring 19, the temperature 21 of the cylinder cover and the comb gap adjustment 22 are conducted via some electrical leads 23 to a pre-control device 24. In the case of an electrical contact of the clothing of the revolving flat 13 with the clothing of the cylinder 4, the electrical short circuit is conducted as a signal to the pre-control device 24 via at least one contact arc 20 (here four) on each side of the carding machine. In particular, in the case of an automatic adjustment of the card nip, a software can be uploaded into the pre-control device 24, which software can determine the contact position more precisely by means of a statistical evaluation in the case of card clothing tip contact. The pre-control device 24 can thus be adapted specifically to the specific requirements of the carding run without having to intervene in the central machine control.
Advantageously, a plurality of pre-control devices 24 can also be used in order to evaluate the sensor data for adjusting the carding nip and for keeping the carding nip constant individually on each side plate 17, for example in a carding machine. The wedge bars on both sides of the cylinder 4 can thereby be independently controlled to adjust the carding gap when one side across the width of the carding machine is subjected to temperature. The two pre-control devices 24 may communicate with each other independently of the machine control device and their data forwarded to the machine control device 26 independently of each other. This also helps to simplify installation and troubleshooting.
A further pre-control device 24 may be arranged in the area of the doffer 5, on the one hand in order to adjust the card clothing distance between the doffer 5 and the cylinder 4, and on the other hand also in order to pre-process data from one or more nep sensors arranged in the area of the doffer 5.
As textile machines are further developed in technology, it is always unavoidable to use more and more sensors and servo drives, so that the signal can be systematically preprocessed by the preprocessing unit 24 according to the invention, and thus the complexity and error-prone nature of the overall system can be reduced. The mounting of the sensors and the servo drive becomes simpler, cheaper and less error-prone, since the electrical leads from the cylinder 4 or in the region of the side plates 17 only need to be connected to the pre-control device 24. Unlike existing and available bus systems of the accessory industry, the bus system used in the pre-control device 24 can be configured individually by software in order to be able to perform any possible control task independently of the machine control device 26, even if very complex.
