Further, if the injection period of the air flow 32 (32a, 32b) is shortened, the continuous injection time of the first airflow 30 can be shortened, thereby preventing an air pressure of a pressure air source 20 from being lowered temporarily.
- the closing valve controller 25 opens the closing valve 22 of the gripping nozzle 12 during the opening of at lest the closing valves 23, 24 of the tuck-in nozzles 18, 19 in response to the instruction from the loom 1 based on the stoppage cause of the loom 1 (weft stoppage), even if the air flow 32 (32a, 32b) is formed, the weft end 37 stays in the airflow entrance port 14 and an operator rotates the loom 1 in reverse to perform the pick finding, thereby extracting the defective weft 16, which is not tucked in the shedding 34 of the warp 33, from the woven cloth 5 with ease.
- the operation to prevent the weft end 37 from being tucked in the shedding 34 of the warp 33 by the injection of the air flow 32 (32a, 32b) by keeping the gripping of the weft end 37 by the first airflow 30 is performed by taking over the operation state of the first airflow 30 at the normal time so that the weft end 37 is prevented from being tucked in the shedding 34 of the warp 33 not owing to the delay of the operation of a control system because the operation itself is not changed.
- the operation to prevent the weft end 37 from being tucked in the shedding 34 of the warp 33 by the injection of the air flow 32 (32a, 32b) while gripping the weft end 37 by the first airflow 30 does not always continue from the operation to pull in and grip the weft end 37 in the airflow entrance port 14.
- the operation to prevent the weft end 37 from being tucked in the shedding 34 of the warp 33 may be interrupted in the middle of the operation thereof.
- the operation to prevent the weft end 37 from being tucked in the shedding 34 of the warp 33 by the injection of the air flow 32 while gripping the weft end 37 by the first airflow 30 is performed by taking over the operation state of a normal airflow, and the closing valve 22 is not operated in the middle of the operation, and hence there is an advantage that the weft end 37 is prevented from being tucked in the shedding 34 of the warp 33 not owing to the delay of the operation.
- the airflow to fold back the weft end is not injected in response to the instruction from the loom, so that the weft end is not tucked in the shedding of the warp, thereby removing the defective weft from the woven cloth with ease.
- the state for gripping the weft end by the first airflow is effected during the injection of at least airflow, so that the weft end is not tucked in the shedding of the warp, thereby removing the defective weft from the woven cloth with ease.
- the gripping operation for preventing the weft end from being tucked in the shedding of the warp by the injection of the airflow among the weft end gripping operations by the first airflow is made after the normal gripping operation by the first airflow, and hence it is possible to cope with the instruction from the loom in good time, thereby reliably preventing the weft end from being tucked in the shedding of the warp.

InFig. 3 , theairflow supply device 4 comprises apressure air source 20,pressure regulators closing valves closing valve controller 25. Thepressure air source 20 is connected to thegripping nozzle 12 via thepressure regulator 21 a, theclosing valve 22 and thegripping pipe 15. Air supplied from thepressure air source 20 is branched at thepressure regulator 21 b. Thepressure air source 20 is connected to the first tuck-innozzle 18 via thepressure regulator 21 b, theclosing valve 23 and the first tuck-inpipe 26, and also connected to the second tuck-innozzle 19 via thepressure regulator 21 b, theclosing valve 24, the second tuck-inpipe 27. Theclosing valve controller 25 opens and closes theclosing valves encoder 29 connected to amain shaft 28 of the loom based on an injection timing set by amain controller 35, and controls injection of air to be supplied to the grippingnozzle 12, the first tuck-innozzle 18 and the second tuck-innozzle 19. - The
main controller 35 performs control necessary for stopping a tuck-in operation in the manner of changing opening and closing control of theclosing valves weft detection sensor 36. Theweft detection sensor 36 is disposed on the side end of areed holder 38 for detecting theweft end 37 of theweft 16, and generating a weft stoppage signal at the time of defective picking, and supplying this weft stoppage signal to themain controller 35. - When picking, the
weft 16 is picked in theshedding 34 of thewarp 33 and theweft 16 is beaten by thereed 8 and is beaten in a cloth fell 6 of thewoven cloth 5. At this time, theweft 16 enters theslit 9 and it is cut by the cutter 7 at its tip. The cut weft end of theweft 16 is drawn by theejector 39 and subjected to a discard process. Thereafter, at the next picking time, the tuck-indevice 2 sequentially injects air through the grippingnozzle 12, the first tuck-innozzle 18, and the second tuck-innozzles 19, whereby a tuck-in operation is performed by an airflow produced at this time to fold back theweft end 37 of theweft 16 together with the airflow in theshedding 34 formed at the next picking time. -
Fig. 4 is a timing diagram showing an air injection timing of respective nozzles relative to the main shaft rotary angle of the loom at the time of normal tuck-in operation. At the time of normal tuck-in operation, the grippingnozzle 12 injects air toward theairflow entrance port 14 for a given period of time to form afirst airflow 30 so that theweft end 37 of theweft 16 cut by the cutter 7 is pulled in theairflow entrance port 14 inside theslit 9 and gripped at the locations of theslit 9 and theairflow entrance port 14. - Then, the first tuck-in
nozzle 18 injects air toward thereed 8 upon elapse of a given period of time from the start of injection by the gripping nozzle 12 (formation of the first airflow 30) to form anair flow 32a as a part of the air flow 32, while the second tuck-innozzle 19 injects air toward theshedding 34 of thewarp 33 upon elapse of a given period of time from the start of injection by the first tuck-in nozzle 18 (formation of theair flow 32a) to form anair flow 32b as a part of the air flow 32, thereby folding back theweft end 37 inside theshedding 34 of thewarp 33. In such a manner, the tuck-indevice 2 performs a tuck-in operation by folding back theweft end 37 inside theshedding 34 of thewarp 33. - The
first airflow 30 is not only formed by the airflow injected from thegripping nozzle 12 but also may be formed by an airflow drawn in the drawing pot of theairflow entrance port 14 and by a plurality of different airflows. - The air flow 32 is formed by only the airflow injected from the injection port and is not formed by the airflow drawn in the drawing port. The air flow 32 is preferable to be formed by the plurality of
airflows -
Fig. 5 is a timing diagram showing air injection timings of respective nozzles relative to the main shaft rotary angle of the loom at the time of non tuck-in operation caused by the weft stoppage. When theweft 16 does not reach theweft detection sensor 36 due to defective picking, for example, due to short picking, theweft detection sensor 36 can not detect theweft 16 so that it outputs a weft stoppage signal to themain controller 35 as a cause of the weft stoppage. Themain controller 35 outputs a valve opening inhibition signal of theclosing valves closing valve controller 25 upon reception of the weft stoppage signal. At this time, although theclosing valve controller 25 allows the grippingnozzle 12 to inject air, it keeps theclosing valves nozzle 18 and the second tuck-innozzle 19 to inject air. Further, the injection by thegripping nozzle 12 may last longer than that during the normal period of time, for example, it may continue or last, for example, until the completion of injection of air by the second tuck-innozzle 19 at the normal time. Meanwhile, the cutter 7 cuts theweft 16 inside theslit 9 after beating in the same manner as the normal picking time. -
Figs. 6(a) and 6(b) show the behavior of theweft 16 in theslit 9 of theblock body 3 at the time of non tuck-in operation. Theweft end 37 advanced inside theslit 9 by the beating of thereed 8 is cut by the cutter 7, then it is inserted in theairflow entrance port 14 by thefirst airflow 30 from the grippingnozzle 12, and thereafter pulled inside and gripped by theairflow entrance port 14. Thereafter, themain controller 35 stops the injection of air by the grippingnozzle 12. - In such a manner, the
closing valve controller 25 breaks off the opening of theclosing valve 23 of the first tuck-innozzle 18 and theclosing valve 24 of the second tuck-innozzle 19 in response to the instruction from the loom 1 based on the weft stoppage causing the stoppage of the loom 1, thereby not forming the air flow 32 (32a, 32b) so that theweft end 37 stays in theairflow entrance port 14 and hence it is not tucked in theshedding 34 of thewarp 33. Meanwhile, ever if thefirst airflow 30 from the grippingnozzle 12 is stopped, theweft end 37 is held in theairflow entrance port 14. - Although the non tuck-in operation is reliably performed by allowing both the
airflows airflows weft end 37 is not folded back in the shedding 34 by the other airflows (e.g., 32a) alone so that the entire air flow 32 is substantially rendered inoperative. Accordingly, "non-operation of the air flow 32 (32a, 32b)" has to be construed to include the case where the air flow 32 is formed of the plurality of airflows, the case where all the airflows are rendered inoperative and the case where only a part of the airflows is rendered inoperative. - Owing to the non tuck-in operation, after the loom 1 is stopped, an operator performs pick finding of the cloth fell 6 by rotating the loom 1 in reverse, thereby extracting a
defective weft 16, which is not tucked in the shedding 34, from the cloth fell 6 of thewoven cloth 5. - If a defective weft removing device is provided on a picking side, not shown, the defective weft removing device receives an instruction from an operator or an instruction from the loom 1, thereby taking the
defective weft 16 therein to automatically remove thedefective weft 16 from the cloth fell 6 of thewoven cloth 5. Thedefective weft 16 is displaced outside a cutting area by the airflow from an exclusive nozzle between a picking nozzle, not shown, and thewoven cloth 5 at the picking side, so as to facilitate the extraction of thedefective weft 16 or a cutter is rendered inoperative, and hence thedefective weft 16 remains to be connected to theweft 16 inside the picking nozzle. - Further, in this embodiment, the tuck-in
device 2 performs the injection of thefirst airflow 30 by the grippingnozzle 12, the injection of the air flow 32 (32a,32b) by the first and second tuck-innozzles Fig. 4 as made as usual, thereby performing the tuck-in operation in the case of the other stoppage cause of the loom 1, for example, a warp stoppage and a manual stoppage of the loom 1. -
Fig. 7 is a timing diagram showing air injection timing of respective nozzles relative to a main shaft rotary angle of a loom at the time of non tuck-in operation according to another embodiment of the invention. A method of performing non tuck-in operation of a shuttleless loom according to the embodiment inFig. 7 is characterized in that aweft end 37 in aslit 9 is not folded back inside a shedding 34 of awarp 33 by injecting afirst airflow 30 from a grippingnozzle 12 during the injection of at least an air flow 32 (32a, 32b) by a first tuck-innozzle 18 and a second tuck-innozzle 19 in response to an instruction from a loom 1 based on a stoppage cause of a loom 1. - A
main controller 35 outputs a valve opening continuation signal to aclosing valve controller 25 upon reception of a weft stoppage signal, and the closingvalve controller 25 keeps the closingvalve 22 in the opening state during a period of time longer than a normal operation time, and injects thefirst airflow 30 from the grippingnozzle 12 during the injection of at least the air flow 32 (32a, 32b) by the first tuck-innozzle 18 and the second tuck-innozzle 19. Meanwhile, the opening of the closingvalve 23 of the first tuck-innozzle 18 and the opening of the closingvalve 24 of the second tuck-innozzle 19 are respectively performed for a period of time in the same manner as the normal tuck-in operation, thereby forming the air flow 32 (32a, 32b). -
Fig .8 shows a behavior of aweft 16 at aslit 9 of ablock body 3 at the time of non tuck-in operation in the embodiment shown inFig. 7 . Theweft end 37 which advanced in theslit 9 by the beating of thereed 8 is cut by the cutter 7, then it is inserted in anairflow entrance port 14 by thefirst airflow 30 from the grippingnozzle 12, and thereafter pulled in and griped by theairflow entrance port 14. Since the injection of thefirst airflow 30 from the grippingnozzle 12 continues until the completion of the injection of the air flow 32 (32a, 32b) from the first tuck-innozzle 18 and the second tuck-innozzle 19, theweft end 37 is pulled in and griped by thefirst airflow 30 and stays in theairflow entrance port 14, and it is not tucked in the shedding 34 of thewarp 33 even if the air flow 32 (32a, 32b) is formed. - At this time, the injecting pressure of the
first airflow 30 from the grippingnozzle 12 is increased compared with that at the normal time to prevent theweft end 37 from being tucked in the shedding 34 of thewarp 33 when theweft end 37 bows to the injection pressure of the air flow 32 (32a, 32b), or the injection pressure of air flow 32 (32a, 32b) is decreased so that theweft end 37 is allowed to stay in theairflow entrance port 14 with assurance to prevent theweft end 37 from being tucked in the shedding 34 of thewarp 33. Further, if the injection period of the air flow 32 (32a, 32b) is shortened, the continuous injection time of thefirst airflow 30 can be shortened, thereby preventing an air pressure of apressure air source 20 from being lowered temporarily. - Since the closing
valve controller 25 opens the closingvalve 22 of the grippingnozzle 12 during the opening of at lest the closingvalves nozzles weft end 37 stays in theairflow entrance port 14 and an operator rotates the loom 1 in reverse to perform the pick finding, thereby extracting thedefective weft 16, which is not tucked in the shedding 34 of thewarp 33, from the wovencloth 5 with ease. - In this embodiment, the operation to prevent the
weft end 37 from being tucked in the shedding 34 of thewarp 33 by the injection of the air flow 32 (32a, 32b) by keeping the gripping of theweft end 37 by thefirst airflow 30 is performed by taking over the operation state of thefirst airflow 30 at the normal time so that theweft end 37 is prevented from being tucked in the shedding 34 of thewarp 33 not owing to the delay of the operation of a control system because the operation itself is not changed. - The operation to prevent the
weft end 37 from being tucked in the shedding 34 of thewarp 33 by the injection of the air flow 32 (32a, 32b) while gripping theweft end 37 by thefirst airflow 30 does not always continue from the operation to pull in and grip theweft end 37 in theairflow entrance port 14. In the case where the injection of the air flow 32 (32a, 32b) starts while delayed from the completion of thefirst airflow 30 at the normal time or in the case where the injection of the air flow 32 (32a, 32b) is temporarily interrupted, the operation to prevent theweft end 37 from being tucked in the shedding 34 of thewarp 33 may be interrupted in the middle of the operation thereof. The manner of operation shown inFig. 7 is a preferable example for continuing the formation of thefirst airflow 30 until the completion of the air flow 32 (32a, 32b). In this case, the operation to prevent theweft end 37 from being tucked in the shedding 34 of thewarp 33 by the injection of the air flow 32 while gripping theweft end 37 by thefirst airflow 30 is performed by taking over the operation state of a normal airflow, and the closingvalve 22 is not operated in the middle of the operation, and hence there is an advantage that theweft end 37 is prevented from being tucked in the shedding 34 of thewarp 33 not owing to the delay of the operation. - According to the first aspect of the invention, in the case where the defective weft is required to be extracted from the cloth fell of the woven cloth owing to the stoppage cause of the loom such as the weft stoppage and the like, the airflow to fold back the weft end is not injected in response to the instruction from the loom, so that the weft end is not tucked in the shedding of the warp, thereby removing the defective weft from the woven cloth with ease. Particularly, since (1) the operation per se for folding back the weft end in the shedding of the warp is rendered inoperative, there is no likelihood that the weft end is erroneously tucked in the shedding of the warp, (2) since the injection of airflow is made after the gripping of the weft, it is possible to cope with the instruction from the loom in good time, and (3) since the non- operation of injection of the airflow is performed by continuing the inoperative state of the injection, and the state of the injection is not changed during that period of time, so that the weft end is not tucked in the shedding 34 of the warp not owing to the delay of the changing operation, and hence the weft end is not reliably tucked in the shedding of the warp.
- According to the second aspect of the invention, when it is required to extract the defective weft from the cloth fell of the woven cloth owing to the stoppage cause of the loom such as the weft stoppage and the like, the state for gripping the weft end by the first airflow is effected during the injection of at least airflow, so that the weft end is not tucked in the shedding of the warp, thereby removing the defective weft from the woven cloth with ease. Particularly, the gripping operation for preventing the weft end from being tucked in the shedding of the warp by the injection of the airflow among the weft end gripping operations by the first airflow is made after the normal gripping operation by the first airflow, and hence it is possible to cope with the instruction from the loom in good time, thereby reliably preventing the weft end from being tucked in the shedding of the warp.
- According to the apparatus of the third aspect of the invention, it can reasonably realize the method of the first aspect of the invention, thereby obtaining the same effect as the method of the first aspect of the invention.
- According to the apparatus of the fourth aspect of the invention, it can reasonably realize the method of the second aspect of the invention, thereby obtaining the same effect as the method of the first aspect of the invention.
- According to the fifth aspect of the invention, since the slit, the gripping nozzle, the first tuck-in nozzle, and the second tuck-in nozzle are respectively disposed in the block body in a reasonable state, a normal tuck-in operation is sequentially effected by airflows, and also non tuck-in operation of the weft can be reliably executed when the first tuck-in nozzle and the second tuck-in nozzle are not operated.
