Japanese Patent Laid-Open No. 2-112449 JP-A 61-239057 Japanese Patent No. 2564877 JP-A-63-175143

  Although the technique of transferring the whole setting value between machine bases like the technique of patent documents 2-patent documents 3 is known, what is transferred between a plurality of setting values in the setting items inside the machine base is , Never existed so far.

  More specifically, the multi-color weft insertion air jet loom is provided with a plurality of main nozzles corresponding to the thread type, that is, the selection number of the weft, and two or more sub nozzles provided along the weft flight path. The main nozzle and sub-nozzle corresponding to the weft are jetted by relay injection. For this reason, the relay injection is performed by opening and closing the solenoid valve corresponding to the nozzle at an injection timing set in advance for each nozzle.

  On the other hand, in order to avoid weft damage during weft measurement, the same weft is set in two or more weft insertion devices, and two or more weft insertion devices provided corresponding to the wefts and two or more weft length measurement storage devices are selected. The weft insertion is performed alternately according to the signal. The same value is set as the setting value corresponding to the weft selection signal in the devices that operate on the wefts of the same yarn type.

  For the operator, regarding the set values such as the nozzle injection timing and the weft unwinding timing in the weft length measuring storage device, the nozzle and weft are output by outputting the weft selection signal while the same weft type is used. A simple setting operation such as setting the same set value for a device to which the length measuring device is selectively operated is troublesome. In addition, since such setting values are frequently adjusted due to changes in the operating status, it is necessary to reset the same set values every time one setting value is changed. There is a problem that it takes time and minutes to reset everything.

  Therefore, an object of the present invention is to save labor in setting the same value to a plurality of setting values in the same setting item in a loom in which a plurality of setting values corresponding to the setting item are set corresponding to the selection number. is there.

  Based on the above object, the present invention sets the same value as a setting value for another selection number after inputting a setting value for one selection number in a setting item by an input operation of a setting device by an operator. In doing so, the setting device can set the same setting value as the setting value of the setting item corresponding to the transfer destination selection number by using the transfer operation of the operator.

  More specifically, the setting value setting method in the loom according to the present invention is an input that allows the setting value for the same setting item as the display device displaying the loom information to be input numerically independently for each selection number of 2 or more. In a loom comprising a setting device having a control device and a controller for storing a setting value for each selection number and controlling a connected electric actuator based on the setting value corresponding to the selection number, After setting a setting value for a setting item in one selection number to the setting device, when setting the same setting value as a setting value for another selection number, the setting device performs the transfer start operation performed by the operator. The input set value is set as a set value of another selection number.

If the weft insertion control is taken as an example with respect to the selection number and the set value for it, it is given as the following storage form. (1) The selection number is composed of a weft selection number, which is information on a device number to be controlled, as an identification number for selecting a setting value for each weft insertion pick number. The setting value for each setting item is a selection number. Is set for each weft selection number. Therefore, more specifically, for each weft selection number determined corresponding to the weft yarn type, the set values of the injection timing and the injection pressure for the weft insertion nozzle are stored, while the weft for each weft insertion pick number. A selection number is stored in advance as a weft selection pattern, and a weft selection number corresponding to a weft insertion pick number that is updated as the loom spindle rotates during loom operation is specified based on the weft selection pattern, and the corresponding number is selected. Read the set value. As an example, the injection timing of a weft insertion nozzle as a setting item is an injection start timing and an injection end timing. When setting the same value as the setting value for a certain weft selection number to the setting value of another weft selection number, the weft selection number that is the transfer destination identification number can be input as display information displayed by the setting device. The display step for displaying the screen is executed, and the operator transfers the set value according to the transfer destination information of the weft selection number input to the setter, and sets it as the set value of the transfer destination selection number.
(2) The selection number is composed of the weft insertion pick number itself as the selection number, and the setting value for each setting item is set for each weft insertion pick number as the selection number. Furthermore, for each weft insertion pick number, a specific number for specifying the weft selection mode, which is a selection number that is the basis of the setting value, is set and stored for each weft insertion pick number. For this reason, a specific number for specifying the weft selection number of the set value stored together with the set values of the injection timing and injection pressure of the weft insertion nozzle for the weft selected for each weft insertion pick number is stored. Accordingly, during operation of the loom, the set value corresponding to the updated weft insertion pick number can be read to drive the corresponding electric actuator. Then, when setting the same value as the setting value for the setting item in a certain weft selection number to the setting value of the setting item in another weft selection number, the weft selection number that is the specific number of the weft insertion pick number as the transfer source is set. On the other hand, each specific number in the remaining weft insertion pick numbers is compared with it, and if they match, the step of setting the input set value as a new setting value for the weft insertion pick number is executed.

  Control of the device to be controlled is performed in the following manner. (1) A plurality of setting values are set for each selection number for the electric actuators of the devices used in common, and the controller sets the setting value corresponding to the updated pick number during the loom operation. To control the electric actuator. As a common device, in the case of a weft insertion device, for example, there is a sub nozzle, and a corresponding electric actuator includes an electromagnetic valve and a pressure control valve for each sub nozzle. (2) During the loom operation, the same setting item, for example, the pressure value, is set for each electric actuator of a plurality of devices that are selectively used. During the loom operation, the controller is updated. The electric actuator selected corresponding to the selected weft insertion pick number is controlled according to the corresponding set value. For the selectively used devices, there are main nozzles, weft length measuring and storage devices, weft brake devices, etc. provided for each weft yarn type. Specific electric actuators include solenoid valves for main nozzles, pressure control valves, There are drive motors for length measuring and storage devices, operating devices such as solenoids for locking pins, motors for weft brake devices, and the like.

  The loom control executed corresponding to the weft insertion pick number includes (1) weft selection control, (2) driving density control, and (3) warp opening control.

  (1) Weft selection control is a multi-color weft insertion loom that selectively inserts wefts corresponding to the weft insertion pick number, and switches setting values of control means related to wefts and weft insertion. The set values for the control means and the control means include the injection timing and pressure value of the weft insertion nozzle (main nozzle and sub nozzle), the operation on / off timing and operation amount of the weft brake device and the weft retracting device, and the weft length measurement storage device. Length measurement (drum diameter / number of windings per pick), advancement / retraction timing of locking pin, parameters related to winding control, unwinding locking control, such as rotation acceleration / deceleration of rotating thread guide, attachment of unwinding sensor The position information and the like are the injection on / off timing and injection pressure of the weft tension device (stretch nozzle), the injection on / off timing and injection pressure of the tack-in device (needle restuck-in device), and the like.

  (2) The driving density control is a weaving machine that can switch the weft driving density to a different value corresponding to the weft insertion pick number. In other words, the tuck-in corresponding to the switching of the driving density, in other words, the switching of the fabric structure. The setting values such as the injection on / off timing and pressure of the device (needleless stack-in device) are switched in accordance with the selection number of the driving density.

(3) The warp opening control is executed by an electric opening device that drives the reed frame by a motor provided for each reed frame. In the electric opening device, a motion curve for the rotation angle of the spindle is created according to the setting parameters (cross timing, opening amount, motion stroke, etc.) input for each collar frame, and each collar frame is driven. The value is transferred to the setting value of the other frame.

  Next, the setting item to which each setting value belongs can be grasped as a minimum unit for each electric actuator and for each operation of the electric actuator. For example, in the case of the first group injection control of the sub nozzle, the injection timing set for each electric actuator (that is, the one including the injection start timing and the injection end timing) is regarded as one setting item, and the two included timings are summarized. May be transferred. Alternatively, each operation of the electric actuator (that is, the injection start timing and the injection end timing may be regarded as one set item and transferred independently).

  Also, different setting values may be used for the setting items depending on the operating state of the loom at the start of operation and during steady operation. For example, when the injection timing is set to a different value in the transient rotation state (1st pick, 2nd pick) after starting the loom and during steady rotation, for example, each injection timing during the transient rotation state or steady operation is set respectively. It may be transferred as a single setting item.

Furthermore, the selection number for specifying the transfer destination selection number with the setting device is not limited to one of the remaining numbers, but two or more or all the remaining selection numbers may be specified and written simultaneously to these. . In addition, the number of setting items transferred by one transfer operation is not limited to one, but two or more items related to the setting items (specifically, for each weft insertion device and each loom state) are transferred collectively. May be.

  According to the present invention, when setting the same setting value as the setting value input for the setting item in one selection number as the setting value for the setting item in another selection number, the specific selection number already input The setting value for the destination is selected as the setting value for the specified transfer destination selection number by another transfer destination selection number and the transfer execution operation. In addition, the time required for setting can be shortened.

[Outline of loom]
FIG. 1 shows a fluid jet loom 1 as a loom. The fluid jet loom 1 is, for example, a two-color weft insertion type, and the two wefts 4 are pulled out from the respective yarn feeders 3 supported by the holders 2 and drums are used as the weft winding type. The drum is guided by the rotational movement of the rotary yarn guide 6 while being guided to the rotary yarn guide 6 of the weft length measuring and storage device 5 and locked by the locking pin 8 on the yarn winding surface by the outer peripheral surface of the drum 7 in a stationary state. It is measured by being wound around the thread winding surface 7 and stored until weft insertion. The rotating yarn guide 6 is driven by a drive motor 43 .

  For the weft insertion operation at the time of weft insertion, when the locking pin 8 is driven by the operating device 9 and retreats from the yarn winding surface of the drum 7, the weft 4 wound around the yarn winding surface of the drum 7 is once. The length required for the weft insertion is unwound on the drum 7 and is guided to the main nozzle 10 for weft insertion through the two guides 36 and 36 and the weft brake device 40 by the traction force of the weft insertion nozzle.

The weft brake device 40 is arranged at a position between the weft length measuring storage device 5 and the main nozzle 10 for weft insertion, and is determined for the weft 4 drawn from the weft length measuring storage device 5 in the weft insertion process. In order to apply a braking force when the braking start timing is reached, a bending type weft brake 42 and a brake driving motor 34 are provided as an example. The bending type weft brake 42 holds the weft 4 in a straight line when no braking force is applied to the weft 4, but when the braking force is applied to the weft 4, the weft brake 42 is set to a predetermined value. By rotating only the angle, the path of the weft 4 is bent, the contact (friction) resistance is increased between the bent portion of the weft 4 and the weft brake 42, and the resistance at this time is used as a braking force.

  The main nozzle 10 has a length necessary for one weft insertion by injecting the pressurized air 15 into the opening 17 of the warp 16 during the injection period from the start of injection to the end of injection for the weft insertion operation. The weft 4 is inserted into the opening 17. As a result, the weft yarn 4 flies along the flying path in the opening 17 and is inserted into the opening 17. The pressure air 15 is supplied from the pressure air source 11 through the pressure adjustment valve 14, the air supply pipe 12, and the electromagnetic on-off valve 13 in the air supply pipe 12 during the injection period for weft insertion. . The pressure regulating valve 14 is provided to set the supply pressure of the pressurized air 15 to the main nozzle 10 to a predetermined pressure value.

  During the weft 4 travel process, one or more groups of sub-nozzles 18 are opened in the direction of travel of the weft 4 by relay injection while harmonizing the pressure air 15 with the travel of the weft 4. The weft 4 flying in the direction 17 is urged in the weft insertion direction. The pressure air 15 of the sub nozzle 18 is supplied from the pressure air source 11 to the sub nozzles 18 of each group through the pressure regulating valve 19, the air supply line 22, and the electromagnetic opening / closing valve 23 in the air supply line 22. The pressure regulating valve 19 sets the pressure air 15 for the sub nozzle 18 to a predetermined pressure value.

  The weft yarns 4 that have been normally weft-inserted by the injection operation of the main nozzle 10 and the plurality of sub-nozzles 18 are beaten on the pre-weaving 21a by the reed 20 and woven as a woven fabric 21, and then supplied on the weft insertion side. It is cut by the cutter 25.

  At the time of weft insertion, the success or failure of the weft insertion is detected by the weft feeler 27 directed to the flying path of the weft 4 (the ridge groove of the deformed kite). The weft feeler 27 opposes the flight path of the weft 4 in the vicinity of the weft end portion on the side opposite to the weft insertion side, and is provided at a position where the weft 4 that has been normally inserted can reach, and within the predetermined detection period, the weft 4 Is detected, the success or failure of the weft insertion is judged, a weft arrival signal is output when normal weft insertion, and a weft stop signal is output when the weft insertion is defective, and these signals are output to the main control unit for each pick. 32.

The drive motor 43 of the weft length measuring and storing device 5, the operation unit 9 of the weft length measuring and storing device 5, the motor 34 of the weft brake device 40, the electromagnetic on-off valve 13 corresponding to the main nozzle 10, and the electromagnetic on-off valve 23 corresponding to the sub nozzle 18. The pressure regulating valves 14 and 19 are both electric actuators and are controlled by the weft insertion control unit 30.

The weft insertion control unit 30 receives a signal of the rotation angle θ of the main shaft 28 from the angle detector 29 connected to the main shaft 28 of the fluid jet loom 1, an operation signal S1 from the main control unit 32, and a weft selection signal generation unit 33. The weft selection signal S2, the rotation speed and the amount of rotation of the drive motor 43 of the weft length measuring and storing device 5 corresponding to the weft 4 selected based on various setting values preset by the setting device 31, and the operation device 9. The locking pin 8 is moved forward and backward, the rotational speed and amount of the motor 34 of the weft brake device 40, the electromagnetic on-off valves 13 and 23 are turned on and off (open / closed), and the pressure adjusting parts of the pressure adjusting valves 14 and 19 are operated. The weft insertion operation of the selected weft 4 is controlled.

  The weft insertion control unit 30, the setting device 31, the main control unit 32, and the weft selection signal generation unit 33 can communicate bidirectionally via the control bus 38. The setting device 31 includes a touch panel having the functions of a display 45 for displaying loom information on the screen and an input device 44 for inputting set values, a CPU 46, and a memory 47 connected to the CPU 46. To the control bus 38. The weft insertion controller 30, the main controller 32, and the weft selection signal generator 33 constitute a controller 41.

As described above, the weft insertion control unit 30 unwinds the weft yarn 4 stored in the wound state around the drum 7 of the weft length measuring storage device 5 by the retraction of the locking pin 8 by the operating device 9 at the time of weft insertion. Then, the unwound weft 4 is inserted into the opening 17 of the warp 16 by the injection action of the main nozzle 10 by the electromagnetic on-off valve 13, and when the braking start timing for the weft 4 is reached, the weft brake 42 is driven by the motor 34. Is rotated by a predetermined angle to generate a braking force on the weft 4, and then the pulling-out of the weft 4 is prevented by the advancement of the locking pin 8 by the operating device 9, thereby completing the weft insertion. During this weft insertion, the weft insertion control unit 30 causes the sub-nozzles 18 to be ejected by an on / off operation of the electromagnetic on-off valve 23.

As described above, the control target of the weft insertion control unit 30 is the drive motor 43 of the weft length measuring storage device 5, the operating device 9, the motor 34 of the weft brake device 40, the electromagnetic on-off valve 13 of the main nozzle 10, and the electromagnetic of the sub nozzle 18. The on-off valve 23 and the pressure adjusting valves 14 and 19 for setting the injection pressure are the electric actuators as described above. The controller 41 controls these electric actuators based on the set value input by the setting device 31.

  Now, the setting method of the set value in the loom according to the present invention is independent for every selection number where the set value for the same setting item as the display 45 displaying the information of the fluid jet loom 1 as the loom is 2 or more. A setter 31 having an input device 44 capable of inputting a numerical value; and a controller 41 for storing a set value for each selection number and controlling a connected electric actuator based on the set value corresponding to the selection number. It is assumed that the loom is provided (fluid jet loom 1). The operator inputs the setting value for one selection number, and then sets the setting value for the same setting item of another selection number, the operator performs a transfer operation of the setting device. At this time, the setting device 31 sets the input setting value as a setting value for the same setting item of another selection number.

[First embodiment]
In the first embodiment, the selection number is configured as an identification number for selecting a setting value for each weft insertion pick number, and a weft selection number that is also used as device number information to be controlled. Is an example that is set for each weft selection number that is a selection number.

More specifically, for each weft selection number determined corresponding to the type of weft yarn, setting values for injection timing and injection pressure as setting items for the main nozzle 10 for weft insertion, setting items for the locking pin 8 The set value of the timing of the forward / backward movement as is input to the input unit 44 of the setter 31, and the set value for each selection number in the setting item and the weft selection number for each weft insertion pick number as the weft selection pattern are selected as the weft selection pattern. Are stored in advance in a memory 47 described later. Then, after an operator inputs a setting value for a setting item at a certain weft selection number, when the same value is set as a setting value for a setting item at another weft selection number, start of transfer performed by the operator By the operation, a display step for displaying a screen that allows the input of a weft selection number that is a transfer destination identification number is displayed as display information displayed by the setting device, and the operator responds to this by displaying the screen on the setting device. The selection number is input, and the setting device transfers the setting value according to the input transfer destination information and sets it as the setting value of the transfer destination selection number. By transferring these set values to the controller 41 according to the transfer destination information of the designated weft selection number, the control conditions are set in the controller 41. During the loom operation, the weft selection number corresponding to the updated weft insertion pick number is specified based on the stored selection pattern, the corresponding setting value is read, and the weft length measuring storage device corresponding to the weft selection number is read. This is an example in which the operating device 9, the electromagnetic on-off valve 13, and the pressure adjusting valve 14 as the electric actuators of the locking pin and the main nozzle for weft insertion are selected and controlled according to the read set value. The main nozzle 10 as a weft inserting device includes an auxiliary main nozzle provided as an auxiliary thereto.

  Particularly, in the first embodiment, in the fluid jet loom 1 of so-called alternating mixing two-color weft insertion in which two wefts 4 of the same color (same weft yarn type) are alternately inserted, the color C1 input to the setting device is used. This is an example in which the setting value of the ejection timing of one main nozzle 10 is set as the setting value of the other main nozzle 10 for the color C2 of the same weft type. In this example, the weft selection signal generator 33 described later changes the weft selection signal S2 according to the weft selection pattern while updating the weft insertion pick number every time the rotation angle θ = 0 ° of the main shaft 28 passes. The two weft insertion devices and the weft length measuring and storage device are selectively operated to select the yarn type of the weft yarn 4. The selection order is C1 for the first pick, C2 for the second pick, and the third pick. Is C1, and the fourth pick is C2,. In this example, the selection number is an identification number (C1, C2) for selecting a set value for each weft insertion pick number (first pick, second pick, third pick, fourth pick,...).

  FIG. 2 shows a process from inputting a set value and transferring the set value in the first embodiment. FIGS. 3 to 6 show the functions of the setter 31 as the input unit 44 and the display unit 45. The example of a display of the input screen 54 in the provided touch panel is shown. In FIG. 2, the worker displays the “main / normal” input display screen 54 of FIGS. 3 to 6 by the input of the input device 44 and the display 45 at the first step p 1 after the start of the process (start). As a result, the on / off timing of the locking pin 8, the main nozzle 10 and the auxiliary main nozzle as setting items for the collar 1 “C1” and the collar 2 “C2” which are selection numbers of the weft 4 is set. Touch the input field 48 to be input the set value. Then, the operation keys 24 are displayed on the same screen on the screen 54 as shown in FIG.

  In the next step p2, the operator touches the operation key 24 to input the operation timing setting value as a setting item in order, and then touches the “ENT” key to enter a numerical value. The displayed operation key 24 disappears from the screen. Thereafter, these input operations are repeated by touching the unset input field 48. As a result, FIG. 4 shows ON (reverse unwinding start timing) 72 °, OFF (forward unwinding stop timing) 260 ° as the set values of the timing of the forward and backward movement of the locking pin 8, and ON (injection) of the main nozzle 10. This shows a state in which start timing (82 °), OFF (injection end timing) 172 °, auxiliary main nozzle ON (injection start timing) 82 °, and OFF (injection end timing) 162 ° are respectively input. The set value data of each timing as each set item in color 1 (“C1”) of the weft selection number at this time is written in the memory 47.

  Here, “C1” and “C2” indicate the wefts 4 of the color 1 and the color 2 as described above, and are the weft selection numbers preset for each weft insertion pick. In this first embodiment, Selection number (identification number). This selection number is a weft selection number preset for each weft insertion pick, and this weft selection number is given for each weft insertion pick by the weft selection signal S2 as the output of the weft selection signal generator 33.

The auxiliary main nozzle is not shown, typically, is provided in series with the main nozzle 10 upstream of the main nozzle 10 in FIG. 1, help the main nozzle 1 0 by the injection operation of the pressure air 15 during the weft insertion. In addition, the display of “1st pick” and “2nd pick” on the screen indicates a 1-pick designation key 35 that is in an excessive operation state immediately after startup, and a similar 2-pick designation key 37. By touching the keys 35 and 37, setting values different from those in the steady operation can be input for two picks (1 pick and 2 picks) immediately after startup.

When the operator visually confirms the input set value, the operator proceeds to the next step p3 to transfer the set value between the weft colors, and touches the transfer start key 26 on the screen 54. The transfer mode 49 of “setting value transfer mode” is displayed on the same screen of the screen 54 as shown in FIG. Then, in step p4, the operator touches the “C1” key 50 which is the “transfer source” weft selection number and the “C2” key 51 of the “transfer destination” to invert the display, and then transfers the transfer. When the execution key 52 is touched, the setting values of the setting items of the locking pin 8, the main nozzle 10, and the auxiliary main nozzle are set to the same values as the setting values of the weft selection number “C1” input so far. The other weft selection number “C2” is transferred and set, and the transfer menu 49 disappears. Then, the process proceeds to step p5, and by this transfer, the color 1 “C1” data is set as the color 2 “C2” data as it is for the locking pin 8, the main nozzle 10 and the auxiliary main nozzle as shown in FIG. Is done. At the same time, the color 1 “C 1” data and the color 2 “C 2” data are stored in the memory 47 and transmitted to the weft insertion control unit 30 and stored in a readable state in the storage area. Is set.

  In this way, the selection number, that is, the weft selection number preset for each weft insertion pick is the alternate weft insertion of two colors as described above, so that the first pick is color 1 “C1”, the first Two picks become color 2 “C2”,. The set value (data) is a device in which color 1 “C1” and color 2 “C2” as weft selection numbers are specified and selectively controlled (locking pin 8 corresponding to color 1 and color 2, main pin Nozzle 10 and auxiliary main nozzle) are input for each operation timing and pressure value of the nozzle as setting items. Although not shown, the sub-nozzles 18 and other devices to be controlled are also input and set on another screen. For example, for the sub-nozzle injection control, as with the main nozzle, it is also possible to vary the injection timing and pressure depending on the weft yarn type. In such a case, those set values for the sub-nozzle are not selected. Input and set on the screen for each weft.

  When the control data as the necessary set value is set in this way, the fluid jet loom 1 is ready for operation. During the operation of the fluid jet loom 1, the controller 41 (weft insertion control unit 30) gives each weft insertion pick with a weft selection signal S2 corresponding to the weft insertion pick number updated as the main shaft 28 rotates. The set values corresponding to the color 1 and color 2 are read out based on the selection pattern of the first pick as the selected weft selection number as color 1 “C1”, the second pick as color 2 “C2”,... Based on the value, the weft insertion is performed by alternately controlling the locking pin 8, the main nozzle 10, and the auxiliary main nozzle corresponding to the weft selection signal.

[Second Embodiment]
In the second embodiment, the weft insertion pick number itself is used as the selection number, and the weft insertion nozzles (main nozzle 10 and sub nozzle 18) are controlled, and the setting values of the injection timing and the injection pressure are set for each weft insertion pick number. This is an example of input.

More specifically, for each weft insertion pick number, setting of injection timing / injection pressure as setting items for the main nozzle 10 for weft insertion, and advance / retreat movement timing as setting items for the locking pin 8 are set. A value is input to the input device 44 of the setting device 31, and each setting value in the setting item and a weft selection number as a specific number based on the setting value can be stored in the memory 47 in correspondence with the weft insertion pick number. Keep it. Then, after an operator inputs a setting value for a setting item in a certain weft selection number, and the same value is set as a setting value for a setting item in another weft selection number, start of transfer performed by the operator The operation reads out the weft selection number which is the specific number of the weft insertion pick number as the transfer source, and compares each specific number in the remaining weft insertion pick numbers with it. The step of setting as a new set value of the input pick number is executed. As described above, the same specific number is transferred as the setting value of the weft insertion pick number, and the control condition including the setting value for each weft insertion pick number is set in the controller 41. In this example, the set value corresponding to the updated weft insertion pick number is read during loom operation, and the electromagnetic on-off valve 23 and the pressure regulating valve 19 as the electric actuators of the weft insertion sub-nozzles are controlled according to the read setting values. During the operation of the loom, the controller 41 sets the corresponding weft measuring length storage device locking pin and the weft insertion main nozzle according to the weft selection number as a specific number read for each weft insertion pick number. As in the first embodiment, control is selectively performed according to the read set values. However, in this embodiment, the detailed description of the transfer of the set values for these is omitted for convenience.

  FIG. 7 shows the configuration of the controller 31 and the like according to the second embodiment, and FIG. 8 shows a display example of the screen on the setting device 31.

  In FIG. 7, the controller 31 has a storage unit 53 instead of the weft selection signal generation unit 33. The storage unit 53 specifies, for each weft insertion pick number, the setting value of the injection timing and the setting value of the injection pressure and the setting value of the main nozzle 10 and the sub nozzle 18 for the selection number of the weft 4 of the selected yarn type. And the weft selection information as the selection number.

FIG. 8 shows a state in which the operator operates the touch panel as the input device 44 to display the input screen on the screen 54. The sub nozzles from the weft insertion pick numbers “N” to “N + 2” are shown. The injection timing set value of the first group is already input. More specifically, in the process up to this point, when the operator inputs the set value of the injection timing of the sub nozzle 18, the input of the input device 44 is performed at the first step p1 after the start of the process. The display 45 displays the “first group” on the “sub / normal” input display screen 54 as shown in FIG. 8, so that the four sub nozzles 18 belonging to the first group, that is, the most weft insertion side, are displayed. Specify a group. Then, the operator operates the two scroll keys 55 for scrolling in the vertical direction of the display screen to display the corresponding weft insertion pick number N, and then the sub-nozzle first group injection timing which is an input field for the setting item to be input next. By touching the column and displaying the operation key 24 in the same manner as in the first embodiment, the injection start timing (ON) 72 ° and the injection end timing (OFF) 180 ° of the sub nozzles 18 of the group are further changed to “ respectively input a number 1 corresponding to the color 1 as weft selection number "to each entry field 48 corresponding. Next, the weft insertion pick number N + 1 is specified, and the sub-nozzle 18 injection start timing (ON) 82 °, injection end timing (OFF) 172 °, and the number 2 corresponding to color 2 as the “weft selection number” is a corresponding input field. 48 are entered in order. The weft selection numbers as specific numbers have already been entered for all weft insertion pick numbers on a separate input screen (not shown). The setter 31 stores these input set values in the storage unit 53 in association with the weft insertion pick numbers.

  Thereafter, the operator sets the injection timing set value of the weft selection number “2” of the weft insertion pick number N + 1 that has already been set, that is, the ON (OFF) timing setting value, and the same weft selection number is set. In order to set one or more weft insertion pick numbers that have been input, the weft selection number field 48 in the transfer source weft insertion pick number “N + 1” and the two injection timing setting values of the transfer source setting item Are touched to press the transfer start key 26 between the weft colors. As a result, the CPU 46 of the setting device 31 sequentially reads out the weft selection number, which is the specific number, from the storage unit 53 for comparison because “2” in the input field 48 of the weft selection number as the specific number is selected. When the read selection number is “2”, the same value as the setting value of the two injection timings whose columns are selected is transferred as the setting value corresponding to the weft insertion pick number and stored in the storage unit 53. The process to be performed is performed on the all weft insertion pick numbers. As a result, the CPU 46 compares the number 2 of the “weft selection number” of the weft insertion pick number N + 2 that is about to be set with the number of the “weft selection number” that has already been input, and the matching weft insertion pick number N + 1. In order to update the display on the screen 54 while setting the set values (injection start timing (ON) 82 °, injection end timing (OFF) 172 °) in the input field 48 of the weft insertion pick number N + 2, The display shown in FIG.

In addition, “normal” of [sub / normal] shown in FIG. 8 indicates a screen for inputting a set value during steady operation. This is not limited to sub-nozzles, and the set values for the main nozzle, locking pins, etc. can be made different depending on the operating state of the loom. The user can press and touch one of the corresponding selection keys 35 and 37 to display each input screen for “1st pick” or “2nd pick” and input a corresponding set value.

  Thereafter, by the same operation, the operator inputs a new set value for other subsequent weft insertion pick numbers, or transfers the set values that have already been input and sets them sequentially. The “weft insertion selection number” here is also a specific number for specifying a setting item, and can be input for each weft insertion pick number. The specific number may be input for each pick when setting a certain weft insertion pick number, or may be input in advance for all weft insertion pick numbers in advance. On the screen, the weft insertion pick number N or less and the weft insertion pick number N + 4 or more can be displayed on the screen by operating the scroll buttons 55 on the left side thereof.

  Although not shown, the setting values of the sub-nozzle 18 injection pressure, the main nozzle 10 injection start timing, the injection end timing, and the injection pressure are also input and set in the same manner after the respective input display screens 54 are displayed. The These set values are stored in the memory 47 and transferred to the storage unit 53 of the controller 41.

  Therefore, during the operation of the fluid jet loom 1, the controller 41 (weft insertion control unit 30) reads the set value corresponding to each updated weft insertion pick number from the storage unit 53, and sets the read setting value. Based on this, the control object is controlled. When the loom main shaft 28 rotates in the forward rotation direction, the weft insertion pick number is set to +1 every time it passes through the rotation angle θ = 0 °, and is sequentially updated.

[Modification]
The first embodiment in which the setting value is switched by the above-described weft selection signal S2 can also be applied to the following setting items related to weft insertion. (1) Weft insertion nozzle, that is, the pressure value of the main nozzle 10, the injection (ON / OFF) timing of the sub nozzle 18, and the pressure value (effective when the timing and pressure are switched according to the weft color. (2) Weft brake device 40 (ON / OFF timing, stroke operation amount), (3) Weft length measurement storage device Other than the operation timing of the locking pin 8 of 5 (when the weft locking operation by the locking pin is performed based on the drum diameter, the winding acceleration, and the yarn signal from the unillustrated unwinding sensor of the weft 4 is attached to the unwinding sensor. position clogging locking pin and unwinding Sen information of the phase difference of Sa) receives the weft yarn 4 in (4) weft stretch device (counter-weft insertion side selvedge, From the end of the insertion until the completion of the beating, for example, in the case where tension is applied to the weft 4 by airflow action, the injection timing of the stretch nozzle, the pressure), (5) Needle restuck-in device (after weft insertion / beating, Tack-in ear forming device that folds back the weft end into the warp opening, which holds the weft end until beating and folds back into the warp opening by airflow. Holding nozzle, jetting timing of return nozzle, pressure, etc.), etc. There is.

  Further, the present invention can be applied to other than the weft insertion relationship. As an example, an electric opening device is assumed in which a warp frame is driven in synchronization with the rotation of the loom by a motor provided for each warp warp frame. As setting parameters for the heel frame, for example, a cross timing for setting the warp closing state, a frame height indicating the vertical position of the heel frame at the cross timing, and a motion curve of the heel frame created corresponding to the loom spindle angle (for example, And a dwell value indicating a period during which the stationary state is maintained at the maximum opening), and an opening amount at the maximum opening. For this reason, it is necessary to set a plurality of these setting parameters in advance for each weft insertion pick number or for each frame, but the same setting value is set for one or more setting parameters as the setting items listed above. In order to do this, the set value may be transferred between weft insertion pick numbers as selection numbers or between each frame. Further, the opening device is not limited to a mode driven for each rib frame, but can be applied to a device in which an electric actuator is provided for each thread, such as an electric jacquard device.

  Although it is not a direct set value for the electric actuator, in the weft insertion control, a set value parameter corresponding to the type of weft yarn (for example, either injection start or injection end based on the deviation amount from the target value of the weft arrival timing) When timing or pressure is controlled, target arrival timing, correction amount (gain), setting values such as correction conditions, etc.) can be considered. Further, as a technique for setting processing conditions for yarn detection, for example, for a weft sensor (weft feeler, yarn feed sensor, take-in detection, etc.) corresponding to a weft yarn type, a yarn signal amplification degree, a threshold It can be applied to set values such as a determination condition for yarn abnormality. Also for these input values, the same values can be transferred by the same method as in the above two embodiments.

  In each embodiment, in addition to the weft selection control, a switching signal corresponding to the rotational state of the loom (fluid jet loom 1) may be used in combination. That is, the injection timing and pressure setting values of the weft insertion nozzle are different between the transient rotation state (1st pick, 2nd pick) immediately after the loom is started and the steady rotation state. As in FIGS. 3 to 6, the data is input and transferred via the setting screen for the transient rotation state. When the loom starts up, the set value for the transient state corresponding to each rotation is selected, and when the steady operation is reached, the set value for the steady operation is selected and controlled.

  Regarding the selection control in each embodiment, in addition to the weft selection control, for example, a woven fabric switching signal (indentation density selection signal) is also conceivable. The above set values are set for each selection number of the fabric structure for the loom capable of switching the setting values of the loom rotation speed, driving density, warp tension, etc. at the time of switching the fabric structure. It can also be used when the same set value is set as the set value.

  The selection number is “number” in the above-described embodiment, but may be in other forms (symbols, letters, symbols, etc.), and substantially the same as “number” is included.

  The present invention can also be applied to a system for automatically determining a set value, and instead of transferring the set value itself, a parameter based on the set value may be transferred. For example, the above set values are listed above for the function of automatically calculating and determining the injection timing pressure of the weft insertion nozzle based on parameters such as weft launch timing, target arrival timing, weft yarn type information, and loom rotation speed It may be read as a parameter.

  The present invention is not limited to the air jet loom but can be used for a water jet loom.
