Japanese Patent No. 2564877

JP-A 63-175143

The present invention relates to a method for inputting and setting various setting values in a loom.

In Japanese Patent Laid-Open No. 2-112449, a plurality of controllers, such as a timing controller for controlling the injection timing of the weft drawing nozzle and the like, and a delivery controller, are connected to transmit and receive information between the setter for control condition input. The operator inputs a setting value for each setting item, such as each injection timing of a plurality of weft drawing nozzles in a multi-color weft drawing loom and a target tension in the control of warp tension, and the setting device is set in each controller. Send the value.

According to the above technique, it is necessary to manually input a plurality of setting values every time the fabric variety is changed, and there is a problem of causing an input error or taking time to set up.

Japanese Patent Application Laid-Open No. 61-239057 discloses a fabric specification connected to a host computer that accumulates setting values corresponding to fabric specifications as a database and a setting machine of the loom so that the host computer can be sent from the setting machine of the loom. A technique for transmitting set value data corresponding to information to a setter and setting this as a set value is disclosed. Also, Japanese Patent No. 2564877 is a technique for transferring setting values between a plurality of looms, and Japanese Patent Application Laid-Open No. 63-175143 as a technique for transferring whole set value data between devices using a memory card as a medium. Etc.

As a technique of Japanese Patent Laid-Open No. 61-239057 and Japanese Patent No. 2564877, a technique for transmitting the whole set value between devices is known, but transfers between a plurality of set values in the setting items inside the device. It did not exist so far.

More specifically, in the multi-color weft draw-in air jet loom, a plurality of main nozzles corresponding to the kind of yarn, that is, the selection number of the weft and two or more sub-nozzles provided along the main lines of the weft are provided. At the time of selecting the weft, the main nozzle and the sub nozzle corresponding to the weft are relay-injected to draw in the weft. Therefore, the relay injection is performed by opening and closing the solenoid valve corresponding to the nozzle at the injection timing set for each nozzle in advance.

On the other hand, the same weft is set in two or more weft drawing devices so as to avoid the damage of the weft when measuring the length of the weft, and the weft selection of the two or more weft drawing devices and the two or more weft length measuring storage devices installed corresponding to the weft are selected. Alternating by the signal, wefts are introduced. In the apparatus acting on the same weft yarn of the same yarn type, the same value is set as a set value corresponding to the weft selection signal.

For the operator, weft selection signals are used while the same weft type is used for the set values such as the injection timing of the nozzle which is a setting item and the weft disengagement timing in the weft length measurement storage device. The simple setting operation of setting the same set value for the device in which the nozzle or the weft length measuring device selectively acts by the output of is cumbersome. In addition, since such set values are frequently adjusted according to changes in operating conditions, when changing a single set value, a portion where the same value is set also needs to be set similarly, and there is a risk of input error or time to reset all of them. There is a problem that this takes.

Accordingly, an object of the present invention is a loom for setting a plurality of setting values corresponding to setting items in accordance with a selection number, and the time and effort required for setting the same value to a plurality of setting values in the same setting item. To save.

For this purpose, the present invention, after inputting a setting value for one selection number in a certain setting item by input operation of a setting device by an operator, sets the same value as the setting value for another selection number. At this time, the setter enables the operator to set the inputted set value as the set value of the setting item corresponding to the selection number of the destination by the operator's transfer operation.

Specifically, the method for setting the set value in the loom of the present invention includes an indicator for displaying the information of the loom and an input device capable of independently numerically inputting the set value for the same setting item for each of two or more selection numbers. In the loom which has a setting device which has, and a controller which memorize | stores a setting value for every said selection number, and controls the electric actuator connected according to the said setting value corresponding to a selection number, an operator selects one to the said setting machine. After setting the setting value for the setting item in the number, and setting the same setting value to the setting value for the other selection number, the setter sets the input setting value by an operation of start of transmission performed by the operator. Is set as a setting value of another selection number.

When the selection number and the setting value thereof are explained, the weft pull-in control is given as an example of the storage form as follows. (1) The selection number is an identification number for selecting a set value for each weft inlet peak number, and is composed of a weft selection number that is information of a device number to be controlled, and the setting value for each setting item is a weft yarn that is a selection number. It is set for each selection number. Therefore, more specifically, the setter is determined corresponding to the type of weft and stores the set value of the injection timing and injection pressure for the weft draw nozzle for each weft select number, while setting the weft select number for each weft draw peak number. The information is stored in advance as a weft selection pattern, and the information is sent to the controller. On the other hand, during the loom operation, the controller updates the weft inlet peak number according to the rotation of the loom spindle, reads the weft selection number corresponding to the weft inlet peak number from the weft selection pattern, and reads out the set value corresponding thereto. The electric actuator can be driven. Enumerating the setting items in this example, there are injection start timing and injection end timing. In the setting device, when setting the same value as the setting value for one weft selection number to the setting value of another weft selection number, a screen allowing input of the weft selection number, which is the identification number of the destination, is displayed as the display information displayed by the setting unit. By executing the display step to be displayed, the setter transmits the set value in accordance with the destination information of the weft selection number input by the operator to the setter, and sets it as the set value of the selection number of the destination.

(2) The selection number constitutes the weft entry peak number itself as the selection number, and the setting value for each setting item is set for each weft entry peak number as the selection number. Further, for each weft inlet peak number, a specific number for specifying the weft selection mode, which is the selection mode on which the set value is based, is set and stored for each of the weft inlet peak numbers. Therefore, for each of the weft inlet peak numbers, the set value of the injection timing and injection pressure of the weft inlet nozzle for the selected weft and the specific number for specifying the weft selection mode of the stored set value are stored, while the controller controls these information. Send to. On the other hand, in the loom operation, the controller can update the weft draw-in pit number according to the rotation of the loom spindle, read the set value corresponding to the updated weft draw-in peak number, and drive the corresponding electric actuator. When setting the same value as the setting value for the setting item in one weft selection number to the setting value of the setting item in another weft selection number, the weft selection number, which is a specific number of the weft inlet peak number, as the transfer destination is read. On the other hand, each specific number in the remaining weft draw peak numbers is compared with that, and when it matches, the step of setting the input set value as a new set value of the weft draw peak numbers is executed.

Control of the control target device is performed by the following aspects. (1) A plurality of setting values are set for each selection number for the electric actuators of devices commonly used, and during loom operation, the controller reads the setting values corresponding to the peak numbers to be updated through the selection numbers to operate the electric actuators. To control. As a common apparatus, in the case of the weft drawing apparatus, for example, there are sub nozzles, and corresponding electric actuators include solenoid valves and pressure regulating valves for each sub nozzle. (2) For each electric actuator of a plurality of apparatuses selectively used during loom operation, the set values are set for the same setting items, for example, pressure values, and during loom operation, the controller updates the weft draw-in peak. The electric actuator selected corresponding to the number is controlled according to the corresponding set value. As the device selectively used, there are a main nozzle, a weft length measurement storage device, a weft brake device, and the like installed for each type of weft. As a specific electric actuator, the solenoid valve for the main nozzle, the pressure regulating valve, and the weft length measurement storage device are driven. Motors, manipulators such as solenoids of locking pins, and motors of weft brake devices.

The control of the loom executed corresponding to the weft pull-in peak number will be explained by (1) weft selection control, (2) type density control, and (3) warp opening control.

(1) The weft selection control switches the set values of the control means relating to the weft and the weft pulling in a multi-color weft pulling loom that selectively pulls the weft yarns in correspondence with the weft pulling-in peak numbers. As the setting values for the control means and the control means, the injection timing and the pressure value of the weft inlet nozzles (main nozzle and sub nozzle), the operation on-off timing and the operation amount of the weft brake device, the weft return device, the weft length measurement storage Measured lengths (drum diameter, number of turns per peak) in the device, parameters for retracting timing of the catch pins, winding control, catch control, eg rotational acceleration and deceleration speed of the rotary seal guide, mounting position information of the sensor Injection on-off timing and injection pressure of the weft tension device (stretching nozzle), injection on-off timing and injection pressure of the tuck-in device (needleless tuck-in device) to be.

(2) Type density control is a tuck-in device (needleless) in response to the conversion of the type density, in other words, the fabric structure, in a loom capable of converting the weft type density to a different value corresponding to the weft inlet peak number. The set values such as the injection on / off timing and the pressure of the tuck-in device) are switched in correspondence with the selection number of the type density.

(3) Warp opening control is performed by a motorized opening device which drives the heald frame by a motor provided for each harness frame. In the electric aperture device, a motion curve for the rotation angle of the main axis is generated according to the setting parameters (cross timing, aperture amount, movement stroke, etc.) input for each light frame, and the respective light frames are driven. To the set value of the other heald frame.

Next, the setting item to which each setting value belongs is demonstrated, and it can handle as a minimum unit for every electric actuator and each operation of an electric actuator. For example, in the case of the first group injection control of the sub-nozzle, two timings included by treating the injection timing (that is, including the injection start timing and the injection end timing) set for each electric actuator as one setting item May be sent together. Alternatively, each operation of the electric actuator, that is, the injection start timing and the injection end timing, may be treated as one setting item and transmitted independently of each other.

Further, it is also conceivable to use different setting values for the setting items depending on the operation state of the loom such as at the start of operation and during normal operation. For example, in the state of transient rotation (first peak, second peak) after starting the loom and in the state of normal rotation, when the injection timing is set to a different value and controlled, for example, in the state of excessive rotation or normal operation Each injection timing may be treated as one setting item and transmitted.

In addition, the selection number at the time of designating the selection number of the destination in the setting device is not limited to one of the remaining ones, but may designate two or more or all the remaining selection numbers and write them simultaneously. The setting items to be transmitted by one transmission operation are not limited to one, but two or more setting items (specifically, for each weft drawer and each loom state) may be transmitted together.

According to the present invention, when setting the same setting value as the setting value input for the setting item in any one selection number as the setting value for the setting item in another selection number, The numerical value input error that has occurred in the past due to manual input by the operator, because the set value for the data is written as the set value of the selected destination number of the designated destination by inputting a different selection number of the destination and performing a transfer operation. This prevents accidents that can occur and ensures reliable setting, and also reduces the time required for setting.

[Overview of the loom]

1 shows a fluid jet loom 1. The fluid injection loom 1 is, for example, in the form of two-color weft draw-in, and the two wefts 4 are drawn out from the respective thread feeders 3 supported by the holders 2, respectively, and the weft winding is performed. The rotating thread guide is guided to the rotating thread guide 6 of the drum type weft length measurement storage device 5 and is caught by the locking pin 8 on the thread winding surface by the outer circumferential surface of the drum 7 in a stationary state. The length is measured by winding on the thread winding surface of the drum 7 by the rotational motion of (6), and is stored until weft entry. The rotary chamber guide 6 is driven by the drive motor 43.

For the weft pull-in operation at the point of weft insertion, when the locking pin 8 is driven by the manipulator 9 and retracted from the thread winding surface of the drum 7, the weft thread wound on the thread winding surface of the drum 7 (4) is made on the drum (7) by the length necessary for one weft draw-in, through the two guides 36 and the weft brake device (40) by the traction force of the weft draw-in nozzle, weft main nozzle 10 Guided by).

The weft brake device 40 is disposed at a position between the weft length measurement storage device 5 and the main nozzle 10 for the weft draw-in, and the weft thread drawn out from the weft length measurement storage device 5 in the weft draw-in process ( For 4), in order to apply the braking force when the determined braking start timing is reached, the curved weft brake 42 and the brake driving motor 34 are provided as an example. The curved weft brake 42 holds the weft 4 in a tension state when the braking force is not applied to the weft 4 in a straight line, but when the braking force is applied to the weft 4, the weft brake ( By rotating 42) by a predetermined angle, the path of the weft yarn 4 is bent to increase the contact (friction) resistance between the bent portion of the weft yarn 4 and the weft brake 42, thereby making the resistance at this time a braking force.

The main nozzle 10 is required for one weft insertion by injecting the pressure air 15 into the opening 17 of the warp yarn 16 in the injection period from the start of injection to the end of the injection for the weft drawing operation. A weft 4 of length is introduced into the opening 17. Therefore, the weft yarns 4 run along the non-main passage in the opening 17 and are drawn into the opening 17. The pressure air 15 is injected from the pressure air source 11 via the pressure regulating valve 14, the air supply pipe 12, and the solenoid opening and closing valve 13 in the air supply pipe 12 to inject the weft yarn. Supplied during. The pressure regulating valve 14 is provided for setting the supply pressure of the pressure air 15 to the main nozzle 10 to a predetermined pressure value.

In the process of fertilization of the weft yarn 4, one or more groups of sub-nozzles 18 spray relays of the pressure air 15 in harmony with the fertilizer of the weft yarns in the direction of the warpage of the weft yarns 4. By pressing, the weft yarns 4 which are arranged in the opening 17 are pressed in the weft drawing-in direction. The pressure air 15 of the sub nozzle 18 passes from the pressure air source 11 through the pressure regulating valve 19, the air supply pipe 22, and the electromagnetic opening / closing valve 23 in the air supply pipe 22. It is supplied to the sub nozzle 18 of a group. The pressure regulating valve 19 sets the pressure air 15 with respect to the sub nozzle 18 to a predetermined pressure value.

The weft yarn 4 which is normally drawn in by the spraying operation of the main nozzle 10 and the plurality of groups of sub nozzles 18 is body by cloth 20 to a cloth fell 21a by a reed 20. After being beaten and woven into the woven fabric 21, it is cut by a yarn cutter 25 on the weft entry side.

At the time of drawing in the weft, whether or not the drawing of the weft is successful is detected by the weft filler 27 directed to the non-periphery path (body groove of the deformed body) of the weft 4. The weft filler 27 is provided at a position where the weft yarn 4 which has been normally inserted can reach the non-main tract of the weft yarn 4 in the vicinity of the weave end portion opposite to the weft penetration. The arrival of the weft 4 is detected within the detection period, the success or failure of the weft pulling is judged, and the weft arrival signal is output at the time of normal weft entry, and the weft stop signal is output at the time of weft entry failure, and these signals are outputted. Each peak is sent to the main control unit 32.

Electrons corresponding to the drive motor 43 of the weft length measurement storage device 5, the manipulator 9 of the weft length measurement storage device 5, the motor 34 of the weft brake device 40, and the main nozzle 10 The on-off valve 13, the electromagnetic on-off valve 23 and the pressure regulating valves 14 and 19 corresponding to the sub nozzles 18 are all electric actuators, and are controlled by the weft draw-in control unit 30.

The weft draw-in control unit 30 is 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, a driving signal S1 from the main control unit 32, a weft yarn. The drive motor of the weft length measurement storage device 5 corresponding to the weft yarn 4 selected according to the weft selection signal S2 from the selection signal generator 33 and various preset values set in advance by the setter 31. Rotation speed and rotation amount of the 43, the forward and backward movement of the locking pin 8 by the manipulator 9, the rotation speed and rotation amount of the motor 34 of the weft brake device 40, the solenoid valve 13, 23 ) The on / off (opening / closing) and the pressure adjusting units of the pressure regulating valves 14 and 19 are operated to control the pulling-in operation of the selected weft 4.

The weft draw-in control unit 30, the setter 31, the main control unit 32, and the weft selection signal generation unit 33 can communicate in both directions by the control bus 38. The setter 31 is connected to the touch panel, the CPU 46, and the CPU 46 having the functions of the display unit 45 for displaying loom information on the screen and the input unit 44 for inputting setting values. Memory 47, which is connected to the control bus 38 by a port 39. The weft draw-in control part 30, the main control part 32, and the weft selection signal generation part 33 comprise the controller 41. As shown in FIG.

As described above, the weft draw-in control unit 30 is wound around the drum 7 of the weft length measurement storage device 5 by the retraction of the locking pin 8 by the manipulator 9 at the time of weft entry. The weft 4 is stored, and the warp yarns 16 are introduced into the openings 17 by the spray action of the main nozzle 10 by the solenoid opening / closing valve 13. When the braking start timing with respect to the weft yarn is reached, the braking force is generated in the weft yarn 4 by rotating the weft brake 42 by a predetermined angle by the motor 34, and then by the manipulator 9. Withdrawal of the weft yarn 4 is prevented by the advancement of the locking pin 8, and the introduction of the weft yarn is terminated. During the weft draw-in, the weft draw-in control unit 30 injects the sub nozzle 18 by the on-off operation of the solenoid valve 23.

In this way, the control target of the weft draw-in control unit 30 is the drive motor 43 of the weft length measurement storage device 5, the manipulator 9, the motor 34 of the weft brake device 40, and the main nozzle 10. The solenoid on / off valve 13 of the sub-), the solenoid on-off valve 23 of the sub nozzle 18, and the pressure regulating valves 14 and 19 for setting the injection pressure are the electric actuators as described above. The controller 41 controls these electric actuators in accordance with the setting values input by the setter 31.

In the method for setting the set value in the loom according to the present invention, the indicator 45 for displaying the information of the fluid jet loom 1 as the loom and the set value for the same setting item are independently for each of two or more selection numbers. A setter 31 having an input unit 44 capable of numerical input, and a controller 41 for storing a set value for each of the selection numbers and controlling the connected electric actuator according to the set values corresponding to the selection numbers. It presupposes the loom (fluid injection loom 1) provided with this. After the operator inputs the setting value for one selection number, and sets the setting value for the same setting item of another selection number, the operator performs a transfer operation of the setter. At this time, the setter 31 sets the input setting value as a setting value for the same setting item of a different selection number.

[First Embodiment]

In the first embodiment, the selection number is an identification number for selecting a setting value for each weft inlet peak number, and is composed of a weft selection number that is also used as information of a device number to be controlled, and the setting value for each setting item is This is an example set for each weft selection number which is a selection number.

More specifically, for each weft selection number determined according to the type of weft, the set value of the injection timing and injection pressure as the setting item for the main nozzle 10 for weft draw-in, and the setting item for the locking pin 8 are described. The set value of the timing of the forward and backward movement is input to the input unit 44 of the setter 31, and each set value for each selection number in the setting item and the weft selection number for each of the weft entry peak numbers as the weft selection pattern in advance are preset. The memory 47 to be described later is stored. When the operator inputs the setting value for the setting item in a certain weft selection number and sets the same value as the setting value for the setting item in another weft selection number, By the start operation, a display step of displaying a screen that enables input of the weft selection number, which is the identification number of the destination, as the display information displayed by the setter is executed, and the operator sends the weft selection number to the setter in a form in response to this. Input, the setter transmits the setting value according to the input destination information, and sets it as the setting value of the selection number of the destination. The control conditions are set in the controller 41 by transmitting these setting values to the controller 41 in accordance with the destination information of the designated weft selection number. During loom operation, the weft selection number corresponding to the weft inlet peak number to be updated is specified based on the stored selection pattern, the corresponding set value is read out, and the locking pin of the weft length measurement storage device corresponding to the weft selection number is read. And an actuator 9, an electromagnetic shut-off valve 13, and a pressure regulating valve 14 as electric actuators of the main nozzle for weft drawing, and are controlled according to the set values read out. The main nozzle 10 as the weft drawing-in apparatus also includes an auxiliary main nozzle that is auxiliaryly installed thereon.

In particular, the first embodiment is for the color C1 input to the setter in the fluid injection loom 1 of the so-called alternate mixing two-color weft inlet, which alternately introduces two wefts 4 of the same color (same weft type). It is an example of setting the set value of the injection timing of one main nozzle 10 as the set value of the other main nozzle 10 for color C2 of the same weft type. In this example, each of the weft selection signal generators 33 to be described later uses the weft selection signal S2 in accordance with the weft selection pattern while updating the weft entry peak number each time the rotation angle θ = 0 ° of the main shaft 28 passes. By changing the two weft drawing device and the weft length measurement storage device selectively, the type of weft 4 is selected, but the order of the selection is that the first peak is C1, the second peak is C2, and the third is selected. The peak is C1, and the fourth peak is C2, .... In this example, the selection number is an identification number C1, C2 for selecting a set value for each of the weft inlet peak numbers (first peak, second peak, third peak, fourth peak ...).

FIG. 2 shows a process of inputting a set value and transmitting the set value in the first embodiment, and FIGS. 3 to 6 function as an input unit 44 and an indicator 45 of the setter 31. The display example of the input screen 54 in the touchscreen provided with this is shown. In FIG. 2, the operator inputs an input display screen of "main normal" of FIGS. 3 to 6 by the input of the input device 44 and the display device 45 at the first step p1 after the start of the process (start). 54), the color 1 " C1 " and the color 2 " C2 ", which are selected numbers of the weft yarns 4, are turned on for the locking pin 8, the main nozzle 10, and the auxiliary main nozzle as setting items. ON) Touch the input field 48 to input the OFF timing setting value. Then, as shown in FIG. 3, the operation key 24 is displayed on the screen 54 on the same screen.

In the next step p2, the operator touches the operation key 24 to numerically input the set value of the operation timing as the setting item by touching the numbers to be input in order and finally touching the "ENT" key, The displayed operation key 24 disappears from the screen. Subsequently, these input operations are repeated by touching the input field 48 not set. As a result, FIG. 4 shows 72 degrees of ON (retreatment and start timing), 260 degrees of OFF (forward and stop timing), and ON (injection) of the locking pin 8 as the set value of the timing of the forward and backward movement. The start timing) 82 °, the OFF (injection end timing) 172 °, the ON (injection start timing) 82 ° and the OFF (injection end timing) 162 ° of the auxiliary main nozzle are shown, respectively. The set value data of each timing as each setting item in color 1 ("C1") of the weft selection number at this time is written into the corresponding storage area in the memory 47.

Here, "C1" and "C2" refer to the weft yarns 4 of the color 1 and the color 2 as described above, and are a weft selection number preset for each weft entry peak, but the selection number in this first embodiment (Identification number). This selection number is a weft selection number set in advance for each weft inlet peak, and this weft selection number is the weft inlet control unit 30 for each weft inlet peak by the weft selection signal S2 as an output of the weft selection signal generation unit 33. Is given.

Although not shown, the auxiliary main nozzle is usually provided in series with respect to the main nozzle 10 on the upstream side of the main nozzle 10 in FIG. 1, and the main nozzle is sprayed by the injection of pressure air 15 at the time of weft entry. Help the nozzle 10. In addition, the display of the "1st peak" and the "2nd peak" on the screen points to the one-peak designation key 35 and the same two-peak designation key 37 to be in the transient operation state immediately after the start, By contacting the keys 35 and 37, setting values different from those in normal operation can be input to two peaks (one and two peaks) immediately after starting.

When the operator visually confirms the inputted setting value, in order to transfer the setting value between the weft colors, the operator proceeds to the next step p3 and touches the transmission start key 26 on the screen 54 so that the setter is The transfer mode 49 of the "set value transfer mode" is displayed on the same screen of the screen 54 as well as entering the transfer mode of the set value. The operator next contacts the key 50 of "C1", which is the weft selection number of "Destination", and the key 51 of "C2" of "Destination", and inverts the display in step p4. By contacting 52, the set values of the timings of the engaging pin 8, the main nozzle 10, and the auxiliary main nozzle, which are setting items, are set to the same values as the set values of the weft selection number "C1" input so far. Is transmitted and set as the set value of the other weft selection number "C2", and the display of the transfer menu 49 disappears. By this transfer, it progresses to step p5 like FIG. 6, and the data of the color 1 "C1" is as data of the color 2 "C2" as it is with respect to the locking pin 8, the main nozzle 10, and the auxiliary main nozzle. It is set and displayed. At the same time, the data of the color 1 "C1" and the data of the color 2 "C2" are stored in the memory 47, transmitted to the weft draw-in control unit 30, and stored as a readable state in its storage area. Is set.

As described above, the weft selection number set in advance for each selection number, i.e., the weft entry peak, is the introduction of two colors of alternate weft as described above, so that the first peak is the color 1 "C1" and the second peak is the color 2 ". C2 " The set value (data) is a device in which color 1 "C1" and color 2 "C2" as the weft selection number are selectively controlled and selectively controlled (locking pins 8 corresponding to color 1 and color 2 and main nozzle 10). And the auxiliary main nozzle) are input for each operation timing as a setting item and the pressure value of the nozzle. Although not shown, the sub nozzle 18 and other devices to be controlled are also inputted and set by other screens. For example, with respect to the injection control of the sub-nozzles common to all the weft yarns, it is also possible to vary the injection timing and the pressure depending on the types of the weft yarns, as in the case of the main nozzles. A setting value is input and set by the screen for every selected weft which is not shown in figure.

In this way, when control data as a necessary set value is set, the fluid-jet loom 1 is in an operable state. During operation of the fluid injection loom 1, the controller 41 (weft draw-in control unit 30) receives the weft draw in according to the weft select signal S2 corresponding to the weft pull-in peak number updated according to the rotation of the spindle 28. The first peak as the weft selection number assigned to each peak reads the setting values corresponding to the colors 1 and 2 based on the selection pattern of the color 1 "C1", the second peak, and the color 2 "C2", ... According to the set value read out, the locking pin 8 corresponding to the weft selection signal, the main nozzle 10, and the auxiliary main nozzle are alternately controlled, that is, selectively driven in response to the weft selection signal to drive the weft yarn. Pull in.

Second Embodiment

In the second embodiment, the weft pull-in peak number itself is a selection number, and the weft pull-in nozzles (main nozzle 10 and the sub-nozzle 18) are controlled. And an example of inputting a set value of the injection pressure.

More specifically, for each of the weft inlet peak numbers, the setting value of the injection timing and injection pressure as the setting item for the main nozzle 10 for weft drawing, and the setting of the timing of the forward and backward movement as the setting item for the locking pin 8 are described. A value is input to the input unit 44 of the setter 31, and the weft selection number as a specific number which is the basis of each set value in the setting item and the set value corresponds to the weft pull-in peak number and the memory 47 I make it possible to memorize). Then, when the operator inputs the setting value for the setting item in a certain weft selection number and sets the same value as this as the setting value for the setting item in another weft selection number, the transmission performed by the operator. When the weft selection number which is the specific number of the weft inlet peak number used as a transfer destination is read by the start operation of a while, each specific number in the remaining weft inlet peak number is compared with it, when the said input is matched, A step of setting the set value as a new set value of the corresponding weft draw peak number is executed. In this way, the same specific number is transmitted as the set value of the weft draw peak numbers recorded therein, and the controller 41 sets a control condition including the set value for each weft draw peak number. During loom operation, the set value corresponding to the updated weft inlet peak number is read, and the solenoid on-off valve 23 and the pressure regulating valve 19 as the electric actuators of the weft inlet sub-nozzle are controlled according to the read out set value. Yes. During operation of the loom, the controller 41 selects the locking pins of the corresponding weft length measurement storage device and the main nozzle for weft insertion according to the weft selection number as the specific number read out for each weft entry peak number. Similarly, selective control is performed in accordance with the read set values, but in this embodiment, detailed description of the transfer of the set values to them is omitted.

7 shows the configuration of the controller 31 and the like according to the second embodiment, and FIG. 8 shows an example of display of the screen on the setter 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 sets the set values of the injection timings and the set pressures of the injection timings of the main nozzle 10 and the sub nozzle 18 with respect to the selected numbers of the weft yarns 4 to be selected for each of the weft inlet peak numbers, and the settings thereof. Weft selection information as a selection number for specifying a value is stored.

In FIG. 8, the operator operated the touch panel as the input device 44, and shows the state which displayed the input screen on the screen 54, The sub nozzle from weft pull-in peak number "N" to "N + 2" The injection timing set value of the first group has already been input. Regarding the process until it reaches this, more specifically, when an operator inputs the setting value of the injection timing of the sub nozzle 18, in the first step p1 after the start of a process, By the input and the display 45, as shown in Fig. 8, by displaying the "first group" on the "sub-normal" input display screen 54, the four sub-nozzles belonging closest to the first group, that is, the weft draw-in side ( 18) specify a group. The operator operates the two scroll keys 55 scrolling in the vertical direction of the display screen to display the corresponding weft entry peak number N, and then the timing of injection of the sub nozzle first group, which is an input field for the setting item to be input thereafter. In the same manner as in the first embodiment, by displaying the operation key 24, the jet start timing ON 72 ° and the jet end timing OFF 180 ° of the sub nozzle 18 of the group are displayed. As the "weft selection number", the number 1 corresponding to the color 1 is input into the corresponding input field 48, respectively. Next, the weft inlet peak number N + 1 is specified, and the number 2 corresponding to color 2 as the jet start timing (ON) of the sub nozzle 18, the jet end timing (OFF) 172 °, and the "weft selection number" are shown. In the corresponding input field 48 in order. And the weft selection number as a specific number has already entered all the weft pulling peak numbers by the separate input screen which is not shown in figure. The setter 31 stores these input set values in the storage unit 53 in correspondence with the weft pull-in peak numbers.

After that, the operator sets the weft selection number "2" of the weft selection number "2" of the weft selection peak number N + 1 which has already been set, that is, the ON-off timing setting value, which is the same as this. Is set to one or more weft inlet peak numbers that are inputted, the two jet timing set values of the column 48 of the weft selection number in "N + 1" which is the weft inlet peak number of the transfer destination and the setting item of the transfer destination. The respective input fields 48 are touched, and their display is inverted or flashed, and the transmission start key 26 between the weft colors is pressed. As a result, the CPU 46 of the setter 31 selects the weft selection number, which is the specific number, sequentially from the storage unit 53, because "2" in the input field 48 of the weft selection number as the specific number is in a selected state. When reading and comparing, when the selected selection number is "2", the same value as the setting value of the two injection timings in the egg selection state is transmitted as the setting value corresponding to the weft pull-in peak number, The process of storing in (53) is performed for all the weft pull peak numbers. As a result, the CPU 46 compares the number 2 of the "weft selection number" of the weft entry peak number N + 2 to be set now with the number of the "weft selection number" already inputted, and matches the weft entry peak number. Screen 54 while setting the set value of N + 1 (injection start timing (ON) 82 °, injection end timing (OFF) 172 °) as a new set value in the input field 48 of weft entry peak number N + 2. In order to update the display of, the display shown in FIG. 8 is obtained.

"Normal" of [sub-normal] shown in FIG. 8 has shown that it is a screen which inputs the setting value in normal operation. This is not limited to the sub-nozzle, and it is possible to vary the set values for the main nozzle, the locking pins, etc. according to the operating state of the loom. On the other hand, the set values of the transient operation state at the time of starting the loom are input. In this case, by pressing any of the corresponding selection keys 35 and 37, respective input screens for "first peak" or "second peak" can be displayed, and corresponding setting values can be input.

Hereinafter, by the same operation, the operator inputs a new set value or transmits a set value already inputted to another subsequent weft entry peak number, and sequentially sets it. The "weft pull-in selection number" here is also a specific number for specifying a setting item, and can be input for every weft pull-in peak number. Although this specific number may be input for every said peak at the time of setting a certain weft inlet peak number, you may input previously all the weft inlet peak numbers collectively. On the screen, the weft pull-in peak number N or less and the weft pull-in peak number N + 4 or more can be displayed on the screen by the operation of the scroll buttons 55 on their left side.

Although not shown, the setting value of the injection pressure of the sub nozzle 18, the injection start timing of the main nozzle 10, the injection end timing, and the setting value of the injection pressure are similarly shown after displaying the respective input display screens 54. It is set by input. These setting values are stored in the memory 47 and transferred to the storage unit 53 of the controller 41.

Therefore, during operation of the fluid jet loom 1, the controller 41 (weft draw-in control unit 30) reads the set value corresponding to each of the updated weft draw-in peak numbers from the storage unit 53, and reads out. The control target is controlled according to the set value. The weft pull-in peak number becomes +1 every time the rotation angle θ = 0 ° passes when the loom main shaft 28 rotates in the forward rotation direction, and is sequentially updated.

[Modification]

The first embodiment in which the setting value is switched by the weft selection signal S2 described above is also applicable to other following setting items in the weft pull-in relationship. (1) It is effective in the specification which switches the weft drawing nozzle ie the pressure value of the main nozzle 10, the injection (ON / OFF) timing of the sub nozzle 18, and the pressure value (timing, pressure for each weft color, and the sub nozzle 18 (2) Weft brake device 40 (ON / OFF timing, stroke operation amount), (3) Other than the operation timing of the locking pin 8 of the weft length measurement storage device 5 (drum diameter, winding acceleration, according to the signal of the yarn from the sensor not shown in the weft thread 4). When the weft locking operation is performed, the mounting position of the seam sensor, that is, the information of the phase difference between the locking pins and the seam sensor, etc., (4) the weft stretching device (receives the weft 4 at the weave end opposite the weft entry, From the arrival end time until the body stroke is completed, For example, in applying tension to the weft yarn 4 by air flow, the timing of injection of the stretching nozzle, pressure, and (5) a needleless tuck-in device (retracting / bodying the weft yarn). Later, in the tuck-in ear forming apparatus which folds the end of the weft into the warp opening, the holding nozzle and the refolding are performed by performing airflow to hold the end of the weft until the body stroke and return the folding into the warp opening. Injection timing of the nozzle, pressure, and the like).

It is also applicable in addition to the weft pull-in relationship. As an example, an electric opening device for driving the heald frame in synchronism with the rotation of the loom is provided by a motor provided for each warp heald frame. As a setting parameter for the seedling frame, for example, a seedling frame created corresponding to the cross timing in the warp closing state, the frame height indicating the vertical position of the seedling frame at the time of the cross timing, and the main shaft angle of the loom. Motion curves (including, for example, a Dowel value indicating the period of time at which the state of rest is at the time of maximum opening), and the amount of opening at the time of maximum opening. Therefore, although a plurality of these setting parameters need to be set in advance for each weft inlet peak number or for each heald, the weft as the selection number is used to set the same setting value for one or more setting parameters as the setting items listed above. The set value may be transmitted between the incoming peak numbers or between each of the healds. In addition, the opening device is not limited to a style driven every frame of light, and can be applied to a device in which an electric actuator is provided for each harness cord, such as an electric jacquard device.

Although it is not a direct setting value for the electric actuator, in the weft inlet control, the timing of either the start of the injection or the end of the injection in accordance with the set value parameter (e.g., the amount of deviation from the target value of the weft arrival timing) corresponding to the type of weft. Alternatively, in the case of controlling the pressure, a target arrival timing, a set value of a correction amount (gain), a correction condition, and the like may be considered. In addition, as a technique for setting processing conditions for detecting a yarn, for example, a weft sensor (weft filler, sudden yarn breakage sensor, continuous pull-in detection, etc.) corresponding to the type of weft, the amplification degree of the signal of the yarn, Application to a set value such as a threshold value, a condition for determining abnormality of a thread, and the like may be considered. Also for these input values, the same values can be transmitted by the same method as 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 of the weft drawing nozzle and the set value of the pressure are different in the transient rotation state (first peak, second peak) immediately after the loom starts and the normal rotation state. 3 to 6, the input through the setting screen for the transient rotation state is transmitted. When starting the loom, select the set value of the transient state corresponding to each revolution, and when the normal operation is reached, select the set value for normal operation and control each.

When the selection control in each embodiment is described, for example, in addition to the weft selection control, for example, a switching signal (type density selection signal) of the fabric structure can be considered. Although the above setting values are set for each selection number of the weaving structure, for the loom which can change the setting values such as the number of revolutions of the loom, the density of the type, and the warp tension at the time of the change of the weaving structure, regardless of the difference in the selection number. In this case, the same setting value can be used for setting the same setting value.

Regarding the selection number, although it is "number" in the said embodiment, it may be in the form of other notation (symbol, character, code | symbol, etc.), and the thing substantially equivalent to "number" is included.

The present invention is also applicable to an automatic determination system of the set value, and instead of transmitting the set value itself, the parameter on which the set value is based may be transmitted. For example, the above-mentioned setting values are enumerated above for the function of automatically calculating and determining the injection timing pressure of the weft drawing nozzle according to parameters such as the weft tapping timing, the target arrival timing, the weft type information, the loom rotation speed, and the like. You can read it and change it as a parameter.

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

According to the present invention, when setting the same setting value as the setting value input for the setting item in any one selection number as the setting value for the setting item in another selection number, The numerical value input error that has occurred in the past due to manual input by the operator, because the set value for the data is written as the set value of the selected destination number of the designated destination by inputting a different selection number of the destination and performing a transfer operation. This prevents accidents that can occur and ensures reliable setting, and also reduces the time required for setting.
