Definitions

  • the invention relates to a thread storage and delivery device of the type specified in the preamble of claim 1.
  • the threading device has directional blowing nozzles and air guide surfaces. If a thread break occurs, e.g. in a predetermined position, with the drive stopped, the free thread end of the broken thread or a reserve thread is brought into the guide opening by activating all directional blowing nozzles from the inlet into the thread storage and delivery device, through the take-up device and then along a diversion with respect to the normal thread path along the storage drum . In the event of a partial accident with a thread break between the inlet and the storage drum, it is ignored that there may still be a proper supply of thread on the storage drum, from which the thread runs properly into the feed opening. The threading process involves unnecessary and time-consuming additional work. Continuous threading is only necessary if the thread supply on the storage drum is used up in the event of a total accident with a broken thread.
  • the invention has for its object to provide a thread storage and delivery device of the type mentioned, in which unnecessary extra work can be avoided in the event of an accident and a partial accident with yarn breakage can be remedied more quickly than a total accident.
  • a thread storage and delivery device which is intelligent with regard to the elimination of an accident is to be created, which is able to classify the respective accident and to correct it in an accident-specific manner with minimal expenditure of time and, if appropriate, automatically.
  • the new thread end is only blown out a little from the outlet of the take-up device so that it can be knotted with the free end on the storage drum, if necessary by an automatic one Knotting device.
  • the other existing directional blowing nozzles are not activated, so that the thread supply present on the storage drum is not destroyed, confused or eliminated and there is also no impairment of the thread in the further thread path downstream of the storage drum.
  • the elimination of the partial accident can be carried out in a short time and without wasting or time for the removal of the existing thread supply.
  • Thread storage and delivery devices that have already been in operation with a compressed air threading device can be easily converted without serious structural modifications.
  • the operating control device either decides which directional blowing nozzles are activated either on the basis of its accessible signals or, for example, by remote control or by the operation of an operator, in order to remedy a partial accident or a total accident.
  • a particularly advantageous automatic embodiment is set out in claim 6.
  • This training takes into account the acute endeavor to largely automate the operation of thread storage and delivery devices.
  • the classification device uses signals which are still present during operation of the device and also after its shutdown, in order to classify the fault and to distinguish whether the thread end only has to be brought to the storage drum or immediately to the guide opening.
  • the troubleshooting is specific to the accident and takes minimal time and automatically.
  • the embodiment according to claim 7 is particularly advantageous because the accident classification device uses existing signals or signals generated in the event of an accident that e.g. show whether the storage drum is empty or still full.
  • the winding element only needs to be placed in the total flow incidence threading position in the event of a total accident. At In the event of a partial accident, the winding member remains in a different position, which is favorable for this accident. For both cases, an intelligent system is created that is able to differentiate between the accidents and to fix each incident in the simplest way, saving time.
  • the embodiment according to claim 9 is structurally simple, wherein the capacity of the microprocessor of the operation control device or of the operation control device itself is used for this additional purpose.
  • a thread storage and delivery device 1 according to FIG. 1, for example for delivering a weft a rapier or projectile weaving machine, not shown, has a base body 4, which supports a drive motor for a hollow shaft 6. At the inlet end (inlet Z) of the base body 4, a cover 7 is fixed. A concentric ring 10 is arranged on the hollow shaft 6. A channel-shaped winding member 9 leads from the inside of the hollow shaft 6 to an outlet 11.
  • permanent magnets 13 are aligned with permanent magnets 15, which are mounted in a storage drum 14 coaxial with the hollow shaft 6. This is rotatably mounted on the hollow shaft 6 (bearing 46) and is blocked by the permanent magnets 13, 15 against rotating.
  • the storage drum 14 defines a storage area 17 for a thread supply V, which consists of adjacent, possibly separated turns of the thread Y applied by the winding element 9.
  • An arm 20 of the base body 4 extends longitudinally and at a distance from the storage drum 14. It holds a central guide opening 22 and is used to accommodate thread sensors, not shown, which are used for operating control and monitoring and generate signals for a control device, not shown.
  • the guide opening 22 can be a closed or slotted thread eyelet or the inlet of a main nozzle (not shown) of the weaving machine.
  • the guide opening 22 can also be arranged on a holder separate from the base body 4.
  • a compressed air transport system is used as the threading device E.
  • a pressure source 25 for example a blower or a compressed air reservoir, is provided for the compressed air supply and is activated via an activation device A and supply lines 26. 27, 28, and optionally 76, in which, for example, quantity or pressure control valves 30 are arranged, can be connected to a plurality of stationary directional blowing nozzles 32, 33, 37, 73 along the thread path.

  • the drive motor (not shown) is rotated forwards or backwards in the crawl gear by the operating control device until the extended locking pin 61 engages.
  • a plurality of recesses 62 can be provided in the ring 10 in order to keep the outlet 11 in at least one predetermined position in the event of a total accident, even in the event of a partial accident.

Furthermore, the activation device A includes inhibition valves 16, 21 in the supply lines 28, 27. In position I, the valves 8, 16, 21 are switched to passage. In position II only the valve 8 is switched to passage, the valves 16, 21, however, are blocked.
  • the activation device A can be operated manually in FIG. 1. It is possible to operate the activation device A remotely. Furthermore, it could also be operated by the operating control device, not shown.
  • the thread Y runs from the inlet Z through the winding member 9, into the supply V and from the supply through the thread brake F and the guide opening 22 to the consumer.

  • Thread sensors If a thread break occurs, which is indicated by not shown Thread sensors are reported, then the thread storage and delivery device 1 and the downstream consumer are shut down and the malfunction is reported.
  • An operator checks whether the thread supply V is still present on the storage area 17 or not. In the event that the supply V is still present, it is a partial accident. To remedy this, the activation device A is switched to position I. By means of the directional blowing nozzle 32, the thread end of the broken thread or a reserve thread is blown over the outlet 11 and then linked to the thread end of the supply V, for which purpose an automatic splicing device is optionally provided. Then the activation device A is switched back to the neutral position N and operation is resumed.
  • the partial accident can be remedied in any rotational position of the winding element 9.
  • the winding member 9 is expediently positioned, for example by the locking pin 61, in a predetermined partial accident threading position.
