Definitions

  • the invention relates to a yarn processing system according to the preamble of patent claim 1 and a yarn feeding device according to the preamble of claim 13.
  • accessory devices are provided along the yarn path from the yarn supply to the exit side from the shed, which serve the yarn control, the yarn treatment, the yarn monitoring, the Fadenabtastung, the yarn conveying, and the like .
  • At least some accessory devices are in signal-transmitting connection with the control device of the yarn feeding device so that feedback or commands can be transmitted or settings of functional parameters are to be made. This means a considerable amount of cabling, generates acute sources of error, and requires a complex equipment and tuning of the communicating components.
  • thread processing systems (weaving machine with yarn feeding devices and accessory devices) in which a fast communication main bus system is provided for serial data transmissions over which communicates, for example, a higher-level control device or the control device of the textile machine with the yarn feeding device and optionally the accessory devices.
  • main bus system information about the speed or angle of rotation of the textile machine and / or the drive of the yarn feeding device may also be transmitted. Since in the operation of the yarn processing system, a plurality of data often have different priorities to be transferred, and modern thread processing systems are extremely complex, the inclusion of accessory devices can overwhelm the capacity of the main bus system or suffers communication with the accessory devices under the dominance of higher-level communications.
  • the intelligence of the main bus system useful for the accessory devices is limited, for example, when the main bus system has to associate a plurality of yarn feeding devices with accessory devices and a jacquard weaving machine. It requires the communication over the main bus system a complex and costly equipment of accessory devices. The data volume to be transmitted may possibly become too large for the main bus system.
  • the invention has for its object to provide a yarn processing system of the type mentioned above and a yarn feeding device for such a yarn processing system in which the above-mentioned disadvantages are avoided and targeted for the communication with accessories devices tailored intelligence is available.
  • the local bus system only connected accessory devices communicate at least with the control device of the yarn feeding device. Parent or higher-level communications do not affect or restrict the accessory data exchange.
  • the local bus system can be tuned with reduced effort to the functions to be performed by the accessory devices and designed with an intelligence that specifically meets accessory devices and provides them with optimum performance Thread control, thread monitoring or thread treatment possible. Serial data transmission in the local bus system provides sufficient speed and reliability.
  • the autonomous design of the local bus system makes this independent of possibly higher-level communication processes of the yarn feeding device in a main bus system.
  • the yarn feeding device operates independently of the textile machine even only depending on the thread consumption, to which the yarn feeding device with the accessory devices in the local bus system automatically monitoring and controlling responding.
  • the local bus system has the advantage of being tailor-made for communication with the accessory devices and therefore easier, for example, in terms of cabling effort, even if they should have a low cost, not directly compatible with a main bus system. This can save costs. Furthermore, accessory devices can be added or removed at any time because the local bus system is very flexible in this respect.
  • each delivery device is a node of a fast communication main bus system through which the yarn delivery devices communicate with each other or with a higher level control device and / or control device of the textile machine, receive commands or information, or provide feedback.
  • a different type of data transmission may take place than in the local bus system.
  • the local bus system of the yarn feeding device for the connected accessories can be a complementary subsystem for the main bus system. Since the requirements for the operation and monitoring or adjustment of accessory devices are lower than for the communication between the textile machine and the yarn feeding devices, the local bus system is slower compared to the fast main bus system, which can reduce the cabling and the cost of the electronic equipment.
  • the yarn feeder with its local bus system for the accessory devices, is able to optimally adapt to the operating conditions and to communicate with the accessory devices with high reliability.
  • the control device of the yarn feeding device is informed about the processes in and at the accessory devices, they can accurately control, adjust, activate or deactivate. Thanks to serial data transmission, even complex data can be transmitted quickly and reliably.
  • the local bus system can be designed to be flexible, so that any number of accessory devices of different types can be connected or disconnected without this having any influence on any higher-level data transmission operations in an optionally existing main bus system.
  • the local bus system usually comes with two conductors, possibly even with only one single conductor connection. Corresponding interface processors or simple microcontrollers or PC boards enable a simple outlay on equipment of the accessory device and in the local bus system.
  • a fast main bus system is considered here to be a CAN bus system with a bit transmission rate greater than 20 kbps, while the slower local bus system only has to be designed for a bit transmission rate of less than 20 kbps (kilobits per second).
  • the local bus system is expediently an introductory subsystem which is complementary to the fast main bus system and which is based on a UART standard equipment of the control of the yarn feeder (Universal Asynchronous Receiver and Transmitter). Because UART ports are by far the easiest way to implement serial communication, and are already available as on-chip peripherals in virtually all reasonably modern microcontrollers. In the UART standard, messages are transferred as a byte-level character.
  • the initiator connection is wired-or-configured and allows bidirectional half-duplex communication. Messages are output by the bus master as a frame. Their specification defines a simple identifier that can be used, for example, to form 60 differently defined messages. Cost-effective low-end microcontrollers can be connected to the UART-standard-based initiator connection, that is to say that only low hardware requirements apply, so that overall a cost-effective, yet reliable local bus system can be created.

  • a simple local bus system with the SYNC line results in relatively high intelligence for operating the accessory devices.
  • a pulse train proportional to the speed can be transmitted on the SYNC line.
  • the accessory device may associate this information with the content of communication in the local bus system without, for example, claiming the control device of the textile machine or the main bus system.
  • the sensor system and / or the drive motor and / or parameter setting devices and / or thread control devices of the delivery device itself can additionally be connected to the local bus system.
  • local bus systems of several yarn feeding devices can be connected to each other at least selectively to a cross-communication. Then data can be transferred from one local bus system to another local bus system, suitably monitored by the control device of a yarn feeding device, which then acts as a master. It is possible to have accessory devices communicate directly with one another, for example, to transmit or query function parameters that apply to several similar accessory devices within the thread processing system.
  • a selectively activatable interface between the main bus system and at least one local bus system may be provided, for example, in or at the control device of the respective yarn feeding device.
