Definitions

  • the present invention relates to an air jet loom with a display device.
  • Japanese Unexamined Patent Application Publication No. 5-51842 discloses that the time of weft yarn release is detected by a weft release sensor provided in a weft measuring and storing device and the time of weft yarn arrival is detected by a weft arrival sensor provided on the side of the reed opposite from the main nozzle.
  • the weft release sensor and the weft arrival sensor detect the time of weft yarn release and the time of weft yarn arrival, respectively, in weft inserting operation for each of different sub-nozzle pressures, and a suitable sub-nozzle pressure is set on the basis of the difference between such times. Specifically, based on the relation between the sub-nozzle pressure and such time difference, the sub-nozzle pressure just before the time difference starts to change is selected and set as the suitable sub-nozzle pressure.
  • a major part of energy consumption in an air jet loom is the compressed air consumption by the main nozzle and the sub-nozzles, and more specifically, the compressed air consumption by the sub-nozzles is more responsible for the energy consumption.
  • selecting sub-nozzle pressure based on the relation between the sub-nozzle pressure and the time difference as disclosed in the above-cited publication No. 5-51842 is an effective method for reducing compressed air consumption while maintaining stable weft insertion.
  • the time difference does not necessarily change clearly depending on the weaving conditions and the fabric conditions.
  • a factor of such unclear change is, for example, the mounting position of the yarn release sensor on the weft measuring and storing device.
  • the time of weft yarn release may not be an actually detected value, but a calculated value. It can be thought that in the latter case the time of weft release tends to be varied and, therefore, the time difference occurs only in an inapparent manner, which makes it difficult to select a sub-nozzle pressure suitable for reducing the compressed air consumption and also may cause unstable weft insertion depending on the selected value of the sub-nozzle pressure.
  • the present invention is directed to providing a n air jet loom with a display device for selection of sub-nozzle pressure which offers stable weft insertion and reduced air consumption.
  • upstream and downstream appearing in the following description are used to denote directions or relative positions with respect to the direction in which a weft yarn is inserted into a warp shed and also in which compressed air supplied from an external source flows.
  • the air jet loom designated by 1 includes a weft insertion device 2, plural sub-nozzles 5 and end nozzles 6 disposed downstream of the weft insertion device 2 along a reed 4 having a number of reed dents 3.
  • compressed air supply line to the weft insertion device 2, the sub-nozzles 5 and the end nozzles 6 is also shown in the form of a block diagram.
  • the weft insertion device 2 has a main nozzle 7 and a tandem nozzle 8 disposed upstream of the main nozzle 7.
  • the main nozzle 7, the sub-nozzles 5, the end nozzles 6 and the reed 4 are disposed on a slay (not shown) and swing back and forth with the slay.
  • the tandem nozzle 8 is fixedly mounted to a frame (not shown) of the air jet loom 1 or to a bracket (not shown either) mounted on the floor.
  • a weft measuring and storing device 11 equipped with a movable pin 10 that is operable to engage with or disengage from a weft yarn Y.
  • the weft measuring and storing device 11 serves to measure a predetermined length of weft yarn Y, i.e.
  • the weft measuring and storing device 11 is equipped with a sensor 12 that detects a balloon formed by the weft yarn Y being released from the weft measuring and storing device 11, for the purpose of detecting the number of releases of weft yarn Y and the angular position of weft release completion, that is the angular position at which release of weft yarn Y from the weft measuring and storing device 11 is completed.
  • Another sensor 13 that detects the arrival of weft yarn Y at the side of the reed 4 opposite from the main nozzle 7, for the purpose of detecting the angular position of weft insertion completion, that is the angular position at which insertion of weft yarn Y is completed, or any failure in weft insertion.
  • the time of weft release completion and the time of weft insertion completion detected by the respective sensors 12, 13 are both recognized as an angular position of the air jet loom 1 which is detected by an encoder 14.
  • the air jet loom 1 in the present embodiment is intended to include two sets of the weft insertion devices 2 and their associated yarn supply packages 9 and weft measuring and storing devices 11, serving as a multicolor weft insertion device.
  • the multicolor weft insertion device may use not only weft yarns of different colors, but also weft yarns of the same color.
  • the sub-nozzles 5 and the end nozzles 6 are used commonly for such two sets of the weft insertion devices 2.
  • the main nozzle 7 is connected through a pipe 16 to a main valve 15 that allows or stops the supply of compressed air to the main nozzie 7.

  • the main air tank 20 is connected through a main pressure gauge 23, a main regulator 24, an initial pressure gauge 25 and a filter 26 to a common air compressor (not shown) installed in a weaving factory.
  • the initial pressure gauge 25 measures initial pressure of compressed air to be supplied from the factory air compressor to the air jet loom 1.
  • the compressed air supplied from the air compressor is regulated to a predetermined pressure by the main regulator 24 and stored in the main air tank 20.
  • the main pressure gauge 23 measures the pressure of compressed air to be supplied to the main air tank 20.
  • the main nozzle 7 is also connected to a breeze circuit 27 that is connected to the pipe 16 at a position downstream of the main valve 15 and bypasses the main valve 15.
  • the breeze circuit 27 has a throttle valve 28 and a breeze regulator 29 and is connected directly to a pipe 30 that connects between the main regulator 24 and the initial pressure gauge 25 both provided upstream of the main air tank 20.
  • the compressed air of initial pressure supplied from the air compressor is regulated by the breeze regulator 29 and the throttle valve 28 of the breeze circuit 27 so that a slight amount of low pressure compressed air is supplied constantly from the breeze circuit 27 through the pipe 16 to the main nozzle 7 and injected from the main nozzle 7.
  • the compressed air thus injected from the main nozzle 7 serves to hold the weft yarn Y remaining in the main nozzle 7 after the completion of weft insertion in an appropriate position.
  • the sub-nozzles 5 are divided into three separate groups.
  • the three groups of sub-nozzles 5 are connected through pipes 32 to respective sub-valves 31 which are fixedly mounted to a frame (not shown) of the air jet loom 1.
  • the sub-nozzles 5 need not necessarily be separated into three groups.
  • four or more groups of sub-nozzles 5 and their associated sub-valves 31 may be provided depending on the weaving width of the loom.
  • the sub-valves 31 are connected through pipes 33 to a common sub-air tank 34.
  • the sub-air tank 34 is connected to a sub-regulator 37 through a pipe 35 that is equipped with a sub-pressure gauge 36.
  • the sub-regulator 37 is connected through a pipe 38 to the pipe 30 that connects between the main regulator 24 and the initial pressure gauge 25.

  • the sub-air tank 42 is connected to a sub-regulator 45 through a pipe 43 that is equipped with a sub-pressure gauge 44.
  • the sub-regulator 45 is connected through a pipe 46 to the pipe 38 that is connected to the pipe 30.
  • the pressure of the compressed air supplied from the air compressor is regulated to a predetermined pressure by the sub-regulator 45 and stored in the sub-air tank 42.
  • the sub-regulator 45 regulates the pressure of the compressed air to be supplied to the sub-air tank 42 to a pressure that is below the pressure of compressed air regulated by the sub-regulator 37.
  • the sub-pressure gauge 44 measures the pressure of compressed air to be supplied to the sub-air tank 42.
  • the end nozzles 6 inject air whose pressure has been regulated below the injection pressure at the sub-nozzles 5, thereby controlling the flight speed of the weft yarn Y just before the completion of weft insertion and also reducing the consumption of compressed air.
  • the main valve 15, the tandem valve 17, the sub-valves 31, the sub-valve 40, the initial pressure gauge 25, the main pressure gauge 23, the sub-pressure gauge 36 and the sub-pressure gauge 44 are electrically connected to a controller 47 of the air jet loom 1 through electric wires 48, 49, 50, 51, 52, 53, 54, 55 and 56.

  • the air jet loom 1 of the present embodiment is so configured that the screen 62 of the display 61 shows a line graph 63 that is indicative of the main nozzle pressure for each of different predetermined sub-nozzle pressures, as shown in Fig. 2 .
  • the line graph 63 is made on the basis of the pressure of the main nozzle 7 when weft insertion is completed at a previously set angular position during weaving operation at various main nozzle pressures under a fixed sub-nozzle pressure.
  • weft insertion is performed for a plurality of times using different main nozzle pressures with the sub-nozzle pressure set at a predetermined value, and the main nozzle pressure with which weft insertion is completed at a previously set desired angular position is selected.

  • the vertical axis represents the main nozzle pressure or the pressure of air injected from the main nozzle 7.
  • Higher main nozzle pressure and sub-nozzle pressure lead to an increased air consumption and an increased energy consumption, while lower main nozzle pressure and sub-nozzle pressure lead to a reduced air consumption and an increased energy saving.
  • the main nozzle pressure is approximately constant at a low level in the range where the sub-nozzle pressure is higher than the pressure P at the point X (such range hereinafter being referred to as high pressure range A), but gradually increases in the range as the sub-nozzle pressure is decreased from the pressure P at the point X (such range hereinafter being referred to as low pressure range B).
  • high pressure range A where the sub-nozzle pressure is high, the flight of weft yarn Y is well assisted and, therefore, weft insertion is completed at the previously set angular position even when the main nozzle pressure is lowered.
  • the main nozzle pressure needs to be increased so as to compensate for less assist of the flight of weft yarn Y by the sub-nozzles 5.
  • weft insertion is completed at the previously set angular position without an increase of the main nozzle pressure.
  • the main nozzle pressure is increased in the low pressure range B, the pressure of the main nozzle 7 to insert weft yarn Y becomes too strong relative to the pressure of the sub-nozzles 5 to assist the fight of the inserted weft yarn Y, which may cause irregular flight of weft yarn Y and hence unstable weft insertion.

  • the controller 47 further has a program that makes the line graph 63 that represents the main nozzle pressure for each of the different predetermined sub-nozzle pressures and also the line graph designated by 65 indicative of the angular position where weft insertion is completed for each of the different predetermined sub-nozzle pressures, and then causes the screen 64 of the display 61 to show such line graphs 63, 65.
  • the operator of the loom can make the screen 64 to show the line graphs 63, 65 as shown in Fig. 3 .
  • the horizontal axis represents the sub-nozzle pressure or the pressure of air injected from the sub-nozzles 5

  • the display device of the second embodiment allows the loom operator to refer to the line graph 65 of the angular position of weft insertion completion and to select the pressure P at the point X or a pressure that is a little higher than the pressure P within the high pressure range A as the sub-nozzle pressure on the basis of the line graph 63. This allows the loom operator to select the optimum sub-nozzle pressure while making sure from the line graph 65 that the angular position of weft insertion completion is stable approximately at the level E, thereby offering stable weft insertion and reduced air consumption.
  • Fig. 4 shows the third embodiment of the display device according to the present invention.
  • the controller 47 has a program that stores a data of the pressure of the main nozzle 7 with which weft insertion is completed at the previously set angular position of the air jet loom 1 for each of the different predetermined sub-nozzle pressures, the angular position of weft insertion completion at such main nozzle pressure and the angular difference between the angular position of weft insertion completion and the angular position of weft release completion.
  • the controller 47 further has a program that makes the line graph 63 that represents the main nozzle pressure for each of the different predetermined sub-nozzle pressures, the line graph 65 of the angular position of weft insertion completion for each of the different predetermined sub-nozzle pressures and the line graph designated by 66 indicative of the above angular difference for each of the different predetermined sub-nozzle pressures, and then causes the screen 67 of the display 61 to show such line graphs 63, 65, 66.

  • the pressure of air injected from the main nozzle 7 or the tandem nozzle 8 is increased so as to increase weft insertion speed and hence to stabilize the angular position of weft insertion completion at the level of E.
  • Increasing the air injection pressure of the main nozzle 7 or the tandem nozzle 8 hastens the weft release completion, thereby increasing the angular difference, that is the difference between the constant angular position of weft insertion completion and the angular position of weft release completion. Excessive increase of the speed of weft insertion by the main nozzle 7 or the tandem nozzle 8 may result in unstable flight of the weft yarn Y and cause unstable weft insertion.

  • the display device of the present embodiment allows the loom operator to select the pressure P at the points X, X1 or a pressure that is a little higher than the pressure P within the high pressure range A as the sub-nozzle pressure on the basis of the line graphs 63, 66 while referring to the line graph 65 of the angular position of weft insertion completion. This allows the loom operator to select the optimum sub-nozzle pressure while checking that the angular position of weft insertion completion is stable approximately at the level of E from the line graph 65.
