Definitions
- the invention relates to a method for monitoring the weft insertion in Air jet looms according to the features of the generic term of the independent Claims 1 and 4.
- the invention further relates to a device for performing the method according to Claim 1 with the features of the preamble of claim 9 and a device for performing the method according to claim 4 with the features of the preamble of claim 12.
- the task is essentially solved by the fact that in the respective level of Weft stretching and detection device available and for detecting a Weft thread breaker provided in the main body of the Device can be moved translationally. This advantageously avoids that an undesired excess length of one in the weft insertion channel of the weft inserted a missing weft break detected.
- DE 195 45 839 C1 discloses a method and a weaving machine for Handling a weft.
- the subject of DE 195 45 839 C1 is the Task based on the formation of catch strips in the fabric production with To avoid inserting edge on air jet looms.
- the task is in essentially solved in that a device for suctioning the weft end section is provided, that of the weft end section to be inserted is cut off. For this is between the insertion device and a first Weft monitor and one arranged after the first weft monitor A suction device is provided for the weft stretching nozzle.
- DE 198 02 254 C1 discloses a weft stretching and detection device for jet looms with two thread guide channels which end in different arrangement levels, the task of which is to minimize the expenditure on weft monitors.
- the task is solved in that both thread guide channels are assigned a weft monitor to detect a long weft or a weft burst.
- EP 0 493 847 A1 and EP 0 645 485 A1 for stretching and detecting one in the entry channel of the reed one Air jet weaving machine of registered weft.
- the correct entry of the Weft thread is checked by a weft guard before the start of the Stretching process detected.
- the object is characterized by the features of the independent Claims 1 and 4 solved.
- the arrival of the free end of the predetermined length of a weft thread inserted, in a manner known per se, after its entry is signaled by a first weft thread monitor, is pneumatically directed from the plane of the weft thread insertion channel to another plane and in which another level, the presence or absence of the end of the predetermined length is detected by an additional weft monitor and, depending on the detection, the weaving process is interrupted or continued.
- the arrival of the free end of the weft thread is therefore not detected by the additional weft thread monitor.
- the missing detection leads to the interruption of the weaving process.
- the free end of the predetermined length of the inserted weft thread is pneumatically steered in a manner known per se from the plane of the weft thread entry into another plane and in the other plane the presence or absence of the end of the predetermined length from a first Weft monitor is detected.
- the weaving process is interrupted according to the feature of claim 6.
- the weaving process is not interrupted if the free end of the weft reaches the first weft monitor and there is no weft break.
- the device for carrying out the method according to claim 1 consists of a first weft monitor 3 arranged on the output side in the plane of the weft insertion channel 2 of the reed 1 of an air jet weaving machine, not shown.
- a so-called auxiliary reed 1a adjoins the weft thread monitor 3 to form a so-called catch bar 8a.
- the auxiliary reed 1a is followed by a weft detection device 6, which establishes a connection deflecting the weft by means of a weft stretching channel 11 to a second weft monitor 4, as is known per se from DE 198 02 254 C1.
- the purpose of the at least one weft monitor 4.5 is disclosed in the previously known document, so that further explanations are not required.
- a second or additional weft monitor 10 is arranged downstream of the weft extension device 6. This rearrangement can take place in the case that the free end of the weft thread is stretched, in a level different from the insertion level of the weft thread, or in the case that the free end of the weft thread is stretched in the insertion level, in the insertion level itself. If there is no loop 9, the free end 7a of the weft thread 7 reaches the thread monitor 10, which triggers a signal to continue the weaving process.
- FIG. 2 shows that the free end 7a of the inserted weft thread 7 passes through the weft monitor 3 was detected, but one at the end of the weft 7 trained sling has not been recognized. Further weft entries were made a defective tissue, as indicated in Figures 2 and 5, arises.
- the weft monitor 10 has recognized that the free end 7a of the Weft 7 is designed as a loop.
- the weaving process is interrupted; Further Weft entries were not made until the error was corrected.
- FIG. 4 shows an alternative solution to the solution disclosed in FIG. 1.
- the first weft thread monitor 3, which according to the invention is arranged between the weft thread stretching device 6 and the weft thread monitor 4, determines whether the weft thread itself has been correctly inserted by the free end 7a of the weft thread 7 reaching or not reaching the weft thread monitor 3 during the stretching process. Failure to reach is an indication of the presence of a loop 9, as shown in FIG. 6; the weaving process is interrupted.
- FIGS. 7 and 8 show possible configurations of the weft monitor 3.4, and 10 shown.
- the weft monitor according to Figure 7 a U-shaped shape 8
- the weft monitor is ring-shaped, with the advantage the low pollution caused by fiber flying.
