Definitions

  • the present device relates to a mispicked weft removing device for a jet loom, for removing a mispicked weft picked by a main picking nozzle.
  • Mispicked weft removing devices for a jet loom, for removing a mispicked weft from the cloth fell of a fabric being woven on the jet loom are disclosed in the Japanese Patent Publications No. (Sho) 56-27621 and (Sho) 62-62167 and Japanese Patent Laid-open No. (Sho) 62-177257.
  • JP No. (Sho) 67-27621 separates a mispicked weft from the cloth fell by the blowing action of a blow nozzle that travels along the cloth fell, and then sucks the floating mispicked weft with a suction pipe capable of entering the shed from the weft picking side to remove the mispicked weft.
  • JP No. (Sho) 62-62167 employs a hooked pushing member provided at its extremity with a nozzle and capable of sliding along the fabric toward the cloth fell.
  • the mispicked weft is separated slightly from the cloth fell by the blowing action of the nozzle before the hooked pushing member engages the mispicked weft to facilitate the hooked pushing member engaging the mispicked weft.
  • JP No. (Sho) 62-177257 employs weft extracting units disposed respectively on the weft picking side and weft arriving side of the loom to extract a broken weft from the both sides of the fabric.
  • JP No. (Sho) 56-27621 that extracts a mispicked weft by suction is not satisfactory in reliability.
  • JP No. (Sho) 62-62167 extracts a mispicked weft by pulling the yarn extending from a supply package and hence this device is effective only when the mispicked weft is continuous with the yarn extending from the supply package. Therefore, if the mispicked weft is broken in the shed, the mispicked weft can not perfectly be removed.
  • JP No. (Sho) 62-177257 is able to remove a mispicked weft even if the mispicked weft is broken in the shed.
  • the weft extracting unit disposed on the weft arriving side fails so suck the free end of the mispicked weft on the cloth fell because of the suction nozzle of the weft extracting unit is located above the cloth fell. That is, a shed must be formed to remove the mispicked weft and it is possible that the extremity of the mispicked weft is unable to reach the suction nozzle when a shed is formed because the reed is separated far from the cloth fell when a shed is formed.
  • the present device provides a mispicked weft removing device comprising a mispicked weft separating unit for separating a mispicked weft from the cloth fell of a fabric being woven on a jet loom, a mispicked weft extracting roller unit disposed on the weft arriving side of the jet loom at which a weft picked by a main picking nozzle arrives, and a leading air current generating unit for generating a leading air current for leading the free end of a mispicked weft into a gripping region in which the mispicked weft extracting roller unit is able to catch the free end of the mispicked weft.
  • the gripping region extends near the weft arriving range and outside the range of swing motion of the reed.
  • the leading end of the weft picked by the main picking nozzle reaches a position beyond a weft arriving position in the weft arriving side.
  • the free end of the weft remaining in the cloth fell is led to the gripping region of the mispicked weft extracting roller unit by the leading air current generated by the leading air current generating unit, and then the free portion of the weft is gripped by a pair of roller of the mispicked weft extracting roller unit. Then the mispicked weft is separated from the cloth fell by the mispicked weft separating unit when a shed that releases the mispicked weft from the warps is formed.
  • the mispicked weft extracting roller unit is actuated to extract the mispicked weft from the shed. Since the gripping region of the mispicked weft extracting unit extends near the cloth fell, the mispicked weft extracting unit is able to grip the leading end of the mispicked weft without fail regardless of the condition of the shed. Thus, the mispicked weft can surely be removed from the fabric.
  • a mispicked weft removing device in a preferred embodiment according to the present device will be discribed with reference to Figs. 1 to 10(b).
  • a weft is measured by and stored on a rotary weft measuring and storing unit 3.
  • the weft measuring and storing unit 3 feeds the weft stored thereon to a main picking nozzle 2 attached to one side of a sley 1.
  • the main picking nozzle 2 picks the weft into a shed at a predetermined point in a weaving cycle so that the weft runs along a path defined by the recesses 4a of a modified reed 4. As shown in Fig.
  • a solenoid 5 is controlled so as to bring a weft stopping pin 5a into contact with the yarn storage surface 3a of the weft measuring and storing unit 3 to stop feeding the weft Y or so as to separate the weft stopping pin 5a from the yarn storage surface 3a to allow feeding the weft Y.
  • the weft Y picked by the main picking nozzle 2 is assisted for running by auxiliary picking nozzles 6 which are actuated sequentially.
  • a first weft detector 7 disposed at a predetermined position, namely, a position between one of the salvages of the fabric W and a trimmed salvage W1, on the weft arriving side, detects if the picked weft Y has arrived at a position corresponding thereto in a predetermined angular range of the weaving cycle.
  • the first weft detector 7 gives information representing the result of detection to a controller C, and then the controller C determines to continue the operation of a main motor M or to stop the same on the basis of the information given thereto by the first weft detector 7.
  • the weft Y When the weft Y is inserted normally, the weft Y is beaten with the modified reed 4 into the cloth fell W2 of the fabric W. Then, the weft Y is cut by an electromagnetic cutter 8 disposed on the side of the main picking nozzle 2 and the weaving operation is continued.
  • the controller C gives a command to stop the main motor M.
  • the loom runs before stopping for about one weaving cycle by inertia after a mispick detection signal has been provided.
  • the mispick detection signal is provided while the sley 1 advances from a position corresponding to the back center toward the fabric W.
  • the sley 1 reciprocates once after driving the mispicked weft Y into the fabric W and stops slightly before the cloth fell.
  • the controller C makes the electromagnetic cutter 8 inoperative immediately after providing the mispick detection signal to keep the mispicked weft continuous with the weft extending between the main picking nozzle 2 and the weft measuring and storing unit 3.
  • the controller C upon the detection of the mispicked weft by the weft detector 7, the controller C gives a weft removal command signal to a mispicked weft removing unit 9 shown in Figs. 4 and 5. Then, a blowing nozzle 10 blows air to blow the weft Y1 continuous with the mispicked weft into a guide pipe 11. The weft Y1 flies through an air guide 12 into a suction pipe 13.
  • a pneumatic actuator 14 presses a driven roller 14a held on the driving rod thereof against a driving roller 15a operatively connected to a motor 15 to hold the weft Y1 between the driven roller 14a and the driving roller 15a. Then, the motor 15 is actuated to pull the weft Y1 and, consequently, the weft Y1 is tightened and is cut by a cutter 2a provided on the main picking nozzle 2, and the mispicked weft is extracted from the shed.
  • the controller C Upon the detection of the complete removal of the mispicked weft from the change of the level of the output signal of a yarn detector 16, namely, a detector consisting of a light projector and a light receiver, the controller C initializes the mispicked weft removing unit 9 and actuates the main motor M to restart the loom. If the removal of the mispicked weft is not completed within a predetermined time, the controller C provides a failure signal.
  • a second weft detector 17 is disposed outside the weft detector 7 disposed on the weft arriving side to detect a weft that runs beyond a weft arriving range near the trimmed salvage W1.
  • a blowing nozzle 18 is attached to the backside of the modified reed 4 at a position between the weft detectors 7 and 17 so as to blow air toward the cloth fell W2.
  • the flow nozzle 18 is connected through a solenoid valve V1 to a compressed air tank, not shown.
  • a suction pipe 19 is disposed beside the trimmed salvage W1 and near the cloth fell W2 with its suction opening on a line aligned with the blowing direction of the blowing nozzle 18. Air is blown by a blowing nozzle 19a connected to the suction pipe 19 to generate suction in the suction pipe 19.
  • the blow nozzle 19a is connected through a solenoid valve V2 to the compressed air tank.
  • a yarn detector 19b consisting of a light projector and a light receiver is provided in the suction pipe 19 at a position near the suction opening of the suction pipe 19.
  • a waste box 20 is provided opposite to the outlet of the suction pipe 19.
  • a motor 21 is disposed on one side of the suction pipe 19, on the side near the trimmed salvage W1, to drive a driving roller 22 through a belt 23.
  • a pneumatic actuator 24 is disposed on the other side of the suction pipe 19 with its longitudinal axis in alignment with the picking direction.
  • a driven roller 25 is supported on the driving rod of the pneumatic actuator 24.
  • the driven roller 25 and the driving roller 22 are disposed respectively on the opposite sides of a gripping region between the blowing nozzle 18 and suction opening of the suction pipe 19 and outside the range of swing motion of the modified reed 4.
  • the driven roller 25 When the driving rod of the pneumatic actuator 24 is projected, the driven roller 25 is moved across the gripping region between the blowing nozzle 18 and the suction opening of the suction pipe 19 and is pressed against the driving roller 22.
  • the driving roller 22 is disposed near the cloth fell W2.
  • the pneumatic actuator 24 is connected through a solenoid valve V3 to the compressed air tank.
  • Temples 26 and 27 are disposed near the cloth fell W1 to guide the salvanges of the fabric W and the trimmend salvage W1.
  • a blowing nozzle 28 is disposed directly above the temple 27 so as to blow air toward the cloth fell W2.
  • a pneumatic actuator 29 is disposed near the blowing nozzle 28.
  • a weft separating hook 29a is attached to the driving rod of the pneumatic actuator 29. When the driving rod of the pneumatic actuator 29 is projected, the weft separating hook 29a scratches the cloth fell W2.
  • the blowing nozzle 28 and the pneumatic actuator 29 are connected respectively through solenoid valves V4 and V5 to the compressed air tank.
  • the solenoid valves V1 to V5 are controlled by the controller C according to the detection signals of the second weft detector 17 and the yarn detector 19b, and the output signal of a rotary encoder 31 for detecting the angular phase of the loom.
  • the controller C executes a mispicked weft removing procedure shown in Fig. 10(a) and 10(b).
  • the leading end of the mispicked weft Y2 driven into the cloth fell W2 is not arrested by the warps of the trimmed salvage W1.
  • the controller C Upon the detection of the weft by the second weft detector 17, the controller C stops the main motor M and energizes the solenoid of the solenoid valve V2 to stop the loom and to make the suction pipe 19 operative. Subsequently, the solenoid of the solenoid valve V1 is energized for a predetermined time to blow air by the blowing nozzle 18 for the predetermined time, so that a leading air current is generated across the gripping region between the blowing nozzle 18 and the suction opening of the suction pipe 19 to lead the leading end Y3 of the mispicked weft Y2 into the suction pipe 19 by the leading air current.
  • the loom After blowing air for the predetermined time by the blowing nozzle 18, the loom is reversed to form a maximum shed to enable the mispicked weft removing unit 9 to carry out the mispicked weft removing operation.
  • This mispicked weft removing procedure is carried out in case a picked weft is broken within the shed, namely, in case one end of the picked weft is continuous with the weft extending within the main picking nozzle 2.
  • the controller C energizes the solenoid of the solenoid valve V5 upon the reception of a yarn detection signal provided by the yarn detector 19b to project the driving rod of the pneumatic actuator 29 so that the free end Y3 of the mispicked weft Y2 is held between the driving roller 22 and the driven roller 25 as shown in Fig. 7.
  • the controller C provides a command to make a threading unit 32 shown in Figs. 4 and 5 including the mispicked weft removing unit 9 carry out a threading operation.
  • a blowing nozzle 34 blows air to pull out the weft from a yarn package 33. Then, the weft is delivered to the weft measuring and storing unit 3 by the converging action of a converging funnel 35. The weft delivered to the weft measuring and storing unit 3 is blown from a weft winding tube 3b by the blowing action of a blowing nozzle 36, and then the weft is guided into an air path between a blowing nozzle 39 and a suction pipe 40 by the cooperative action of blowing nozzles 37 and a funnel 38. As shown in Fig.
  • the weft Y4 thus unwound from the yarn package 33 is transported by an air current flowing from the blowing nozzle 39 toward the suction pipe 40 and is sucked into the suction pipe 40.
  • An excessive portion of the weft Y4 held by the suction pipe 40 by suction is cutt off with a cutter 41.
  • a catching lever 42a which is driven by a motor 42 for swing motion between a position indicated by continuous lines and a position indicated by alternate long and two short dashed lines in Fig. 8 hooks the weft Y4 and takes the same to a position near the inlet of the main picking nozzle 2.
  • the main picking nozzle 2 sucks and picks the weft Y4 by its blowing action, and the weft Y4 is blown into the guide pipe 11 by air blown by the blowing nozzle 10.
  • the mispicked weft removing unit 9 carries out the mispicked weft removing procedure and the cutter 2a cuts the weft Y4 to complete the threading operation of the threading unit 32.
  • the solenoid of the solenoid valve V4 is energized for a predetermined time to separate the mispicked weft Y2 slightly from the cloth fell W2 by blowing air through the blowing nozzle 28 for the predetermined time.
  • the solenoid of the solenoid valve V5 is energized to project the driving rod of the pneumatic actuator 29 and, conseuqently, the weft separating hook 29a scratches the cloth fell W2 to separate further the mispicked weft Y2 slightly separated from the cloth fell W2 by tje blowing action of the blowing nozzle 28 from the cloth fell W2. Since the mispicked weft Y2 is separated beforehand by the blowing action of the blowing nozzle 28, the weft separating hook 29a is mispicked weft Y2 without fail.
  • the motor 21 is actuated to extract the mispicked weft Y2 from the fabric and to deliver the mispicked weft Y2 toward the suction pipe 19 by rotating the driving roller 22 and the driven roller 25.
  • the mispicked weft Y2 is sucked into the suction pipe 19 and is discharged into the waste box 20.
  • the yarn detector 29b gives a signal indicating the absence of yarn to the controller C, and then the controller C stops the motor 21 and provides a signal to de-energize the solenoids of the solenoid valves V2, V3 and V5. Consequently, the weft separating hook 29a is retracted to its standby position, the driven roller 25 is separated from the driving roller 22, and the suction of the suction pipe 19 is stopped.
  • the threading unit 32 carries out the foregoing threading operation.
  • the results of the threading operation of the threading unit 32 is evaluated from the output signal of the yarn detector to see if the threading operation has been successful. If the threading operation and the mispicked weft removing procedure have successfully been achieved, the loom is restarted. If either the threading operation or the mispicked weft removing procedure has not successfully been achieved, an alarm is provided.
  • the free end Y3 of the mispicked weft Y2 is very short. Accordingly, a region for the removal of a weft mispicked due to faulty yarn feed or the breakage of the weft in the shed can be expanded by disposing the second weft detector 17 close to the first weft detector 7 to increase remarkably the success probability of the weft removing operation.
  • the present device is not limited in its practical application to the foregoing embodiment.
  • the weft separating hook 29a may be disposed under the fabric W as shown in Fig. 11.
  • a suction nozzle 43a is fitted slidably on a suction pipe 43, a lever 44 having one end interlocked with the driving rod of a pneumatic actuator 24 and the other end interlocked with the suction nozzle 43a is supported for swing motion on a support shaft 45, a driving roller 22 to be driven by a motor 21 is disposed near the trimmed salvage, and a driven roller 25 is supported on the extremity of the driving rod of the pneumatic actuator 24.
  • the suction nozzle 43a When the driven roller 25 is advanced toward the driving roller 22, the suction nozzle 43a is moved away from a gripping region in which the rollers 22 and 25 grip the free end of a mispicked weft by the lever 44, and the suction nozzle 43a is advanced into the gripping region by the lever 44 when the driven roller 25 is moved away from the driving roller by the pneumatic actuator 24.
  • the suction nozzle 43a When the driven roller 25 is retracted from the gripping region as shown in Fig. 12, the suction nozzle 43a is loacted within the gripping region.
  • the suction nozzle 43a When the driven roller 25 is pressed against the driving roller 22 as shown in Fig. 13, the suction nozzle 43a is moved away from the gripping region.
  • the suction nozzle 43a can be advanced as near to the cloth fell W2 as possible in sucking the free end Y3 of a mispicked weft Y2 by the suction pipe 43 to ensure further the suction and mechanical gripping of the free end Y3.
  • the device for removing mispicked wefts in an air jet loom includes a weft separating unit 29, 29a for the separation of the mispicked, i.e. broken weft Y from the cloth fell W2.
  • the free end of the mispicked weft Y is blown into a so called gripping area or region where the end of the broken weft Y is caught e.g. by rollers 22, 25 of the weft extracting unit 19, 19a, 19b, 20, 21, 22, 23, 24, 25.
  • the gripping region of of the extracting unit extends close to the weft arriving side but outside the range of the motion of the reed 4 of the loom.
