Description

  The present invention facilitates a weft insertion condition setting change operation when a correspondence relationship between a weft and a weft insertion series is changed in a multi-color weft insertion loom equipped with a weft insertion device having a plurality of weft insertion series. , Regarding the setting method.

  In a recent general loom, a plurality of weft insertion-related devices (length measuring storage device, main nozzle, sub nozzle, etc.) operate in cooperation to realize one weft insertion. The group to which these weft insertion related devices belong is called “weft insertion series” in this application.

  In addition, the multi-color weft insertion loom includes a plurality of weft insertion sequences, and a different selection number is assigned to each weft insertion sequence. For example, in the case of a six-color weft insertion loom, one of selection numbers 1 to 6 is assigned to each weft insertion series. Then, the weft insertion control device specifies a weft insertion sequence that operates according to the selection number.

  In general, the correspondence between each weft insertion related device and the weft insertion sequence to which each weft insertion related device belongs is fixed. Specifically, when the loom is a six-color weft insertion loom having six length measuring storage devices f1 to f6 and six main nozzles n1 to n6, the length measuring storage device f1 and the main nozzle n1 are inserted. Correspondence between each weft insertion related device and weft insertion series, corresponding to series 1 (selection number 1), length measuring storage device f2 and main nozzle n2 corresponding to weft insertion series 2 (selection number 2) The relationship is fixed. In other words, the length measuring storage device in the weft insertion series 1 of selection number 1 is the length measuring storage device f1, the main nozzle is the main nozzle n1, and only the main nozzle is changed to the main nozzle n2. Is not done.

  In such a multi-color weft insertion loom, the weft insertion pattern and the control value are preset in the weft insertion control device by the setting device. The “weft insertion pattern” here refers to a pattern in which the operation order for each pick in the weft insertion series is determined by a selection number. The “control value” refers to a value for controlling the weft insertion related device belonging to each weft insertion series, and is set in a form corresponding to the selection number. For example, the injection pressure and the injection timing at the weft insertion nozzle These are the operation amount and operation timing of the yarn winding arm driving motor in the length measuring storage device. These control values (including selection numbers) and weft insertion patterns are collectively referred to as “weft insertion conditions”.

  The control value is determined in accordance with the type of weft thread inserted in each weft insertion series, and is set in a form associated with the selection number assigned to the corresponding weft insertion series. The operation of each weft insertion-related device in each weft insertion series is controlled according to the weft insertion conditions set in the weft insertion control device.

  By the way, in a multi-color weft insertion loom having a plurality of weft insertion sequences as described above, if the result is not as expected as a result of actual weft insertion according to the set weft insertion conditions, weft insertion is performed. The correspondence between the weft and the weft insertion series may be changed. Specifically, for example, in a multi-color weft insertion loom having two wefts C1 and C2 and two weft insertion lines 1 and 2, one weft C1 is inserted by one weft insertion line 1 and the other It is assumed that the correspondence is established so that the other weft C2 is inserted by the weft insertion series 2. As a result of actual weft insertion, if the result is not expected, for example, when there are many stops at the time of weft insertion of one weft C1, the other weft C2 is weft-inserted by one weft insertion series 1, and the other The weft insertion sequence 2 may change the correspondence so that one weft C1 is inserted.

  When the correspondence is exchanged in this way, it may be necessary to exchange the weft insertion conditions set in the weft insertion control device.

  For example, in a multi-color weft loom that wefts different types of wefts in two weft insertion series, the weft insertion conditions are set in the weft insertion control device according to the type of weft, so It is necessary to replace the weft insertion conditions with the replacement. Conventionally, in order to replace the weft insertion conditions, the operator displays the setting values of the weft insertion conditions of each weft insertion series on the display screen of the setting device, and changes the thread type among the setting values. For the corresponding part (part or all), set (input) again to change the setting value of the weft insertion condition in one weft insertion series to the setting value of the weft insertion condition in the other weft insertion series, and the other weft The setting value of the weft insertion condition in the insertion series was similarly set to the setting value of the weft insertion condition in one weft insertion series.

  Also in a multi-color weft insertion loom that wefts the same type of weft in two weft insertion series, each weft has a slightly different physical property of the weft and the winding pressure of the yarn supply, etc. In some cases, different weft insertion conditions are set for the insertion series. In this case as well, it is necessary to change the weft insertion conditions in accordance with the exchange of the corresponding relationship as in the case where the types are different.

  In any of the cases described above, the operator re-enters the set values of the respective weft insertion conditions, and much time and effort are required for the input work.

  Patent Document 1 described later discloses a multicolor weft insertion loom entitled “Setting Method of Setting Values in Loom”. In this document, there is no description regarding exchanging the weft insertion conditions of the two weft insertion sequences as described above. However, in this document, a control value for a weft insertion condition is set in the weft insertion control device, and a control value set for one weft insertion series is copied and set as a control value for another weft insertion series. It is described.

JP 2006-70410 A

  An object of the present invention is to facilitate a setting change operation of a weft insertion condition when a correspondence relationship between a weft thread to be inserted and a weft insertion series is changed in a multicolor weft insertion loom.

  The present invention relates to a weft insertion device comprising two or more weft insertion sequences composed of a plurality of weft insertion-related devices operating at the time of weft insertion, and a selection number assigned to each weft insertion sequence is determined as a selection order for each pick of weft insertion. A setting device that sets control values for controlling the operation of the weft insertion related devices belonging to each weft insertion pattern and each weft insertion series, and a weft insertion pattern and a plurality of control values are preset by the setting device as weft insertion conditions In addition, a weft insertion control device in which a control value is set in a form corresponding to the selection number, and controls the operation of each weft insertion-related device in the weft insertion sequence selected according to the weft insertion pattern according to the control value. A multi-color weft insertion loom including a weft insertion control device for executing weft insertion by a weft insertion related device is assumed.

  And the setting method of the weft insertion conditions in the multi-color weft insertion loom includes a first step in which the operator selects two weft insertion sequences corresponding to the wefts to be replaced in the setting device, and a replacement command signal based on the first step. In accordance with the occurrence of the above, the replacement of the control values of the weft insertion-related devices to be replaced for the two weft insertion sequences selected in the first step includes the second step executed by the setting device. And

  Further, it does not matter whether or not the weigh insertion related devices belonging to the weft insertion series are preset for control value replacement. In order to make it easier for an operator to grasp such a replacement target, it is desirable to do the following. In other words, in the first step, the setting method of the weft insertion condition is that the operator selects the weigh insertion related devices belonging to the weft insertion series individually or collectively for the control value replacement target. is there.

  When the control values are exchanged between two weft insertion sequences, a pattern failure occurs unless the selection numbers defined as the selection order are also exchanged in the weft insertion pattern. This replacement of the selection numbers may be performed manually by the operator, one by one. However, in order to simplify the work, the weft insertion pattern as a replacement target must be set in advance, or it must be selected later if it is not set in advance. Then, the setting work can be simplified as follows. That is, in this second setting method of weft insertion conditions, in the second step, when the replacement command signal is generated, the selection number of the weft insertion pattern to be replaced is set for the two weft insertion sequences selected in the first step. Replacing is performed by the setter.

  According to the setting method of the weft insertion condition of the present invention, when the correspondence between the weft and the weft insertion series is exchanged as described above, the weft insertion for every two weft insertion series that is inevitably caused by the exchange is performed. The change of the control value (setting value) of the condition is not set again by the worker, but by the replacement of the control value that has already been set, and the operator in the first step of generating the replacement command signal Since it can be automatically performed in the second step by the selection operation, the time and labor for changing the setting of the weft insertion condition is greatly reduced.

  Further, according to the setting method of the weft insertion condition of the present invention, among the weft insertion related devices belonging to the weft insertion series, those for which control values are to be replaced are set in advance, and selected from them in the first step By making it possible, the setting work is facilitated. And in the selection, it becomes possible to replace only the necessary control values by making it possible to individually select the respective weft insertion-related devices. However, since there are many cases where they are basically replaced at a time, it is possible to select many weft insertion-related devices to be replaced in a batch with a selection function as described above. In some cases, the work can be further simplified.

  According to the weft insertion condition setting method of the present invention, the weft insertion condition is set by associating the control value of each weft insertion related device with the selection number assigned to each corresponding weft insertion series. However, when the control value is exchanged while the correspondence between the weft insertion series and the selection number is fixed, it is necessary to also exchange the selection number in the weft insertion pattern. The replacement of the selection number is also automatically performed in the second step, so that the work can be further simplified.

It is explanatory drawing of the principal part of the weft insertion apparatus of an air injection type loom. It is explanatory drawing of the display screen for replacement of the weft insertion conditions of a setting display apparatus. It is explanatory drawing which shows the weft insertion pattern in a weaving pattern.

  FIG. 1 shows a main part of a fluid injection type (air injection type) multicolor weft insertion loom as a multicolor weft insertion loom to which the present invention is applied. Although only two weft insertion sequences are shown in FIG. 1, it is assumed that the four-color weft insertion device 11 actually has four weft insertion sequences, and will be described below based on that assumption. In the weft insertion device 11 of FIG. 1, the wefts 14 of the collars C1, C2,... Are pulled out from the yarn feeder 13 supported by the yarn feeder stand 12, and are, for example, a drum type length measuring storage device 15. The yarn is wound around the outer peripheral surface of the drum 17 by the rotational movement of the yarn winding arm 16 while being guided to the inside of the yarn winding arm 16 and being locked by the locking pin 18 on the outer peripheral surface of the drum 17 in a stationary state. Accordingly, the weft 14 having a length necessary for one weft insertion is wound around the outer peripheral surface of the drum 17 and stored until the weft 14 is inserted.

  The length measuring storage device 15 (the rotational movement of the yarn winding arm 16 and the forward and backward movement of the locking pin 18) and the main nozzle 21 for weft insertion described later are inserted into the weft insertion control device 43 in the loom control device 42. The controller 44 operates based on the selection order of the wefts 14 defined in the weft insertion pattern (also referred to as “weft selection pattern”).

  At the weft insertion start timing, the locking pin 18 corresponding to the weft 14 selected by the weft insertion control unit 44 is driven by the operating device 19 and retracted from the outer peripheral surface of the drum 17 to be wound around the outer periphery of the drum 17. The weft 14 having a length necessary for one weft insertion can be unwound on the drum 17. The weft 14 passed from the drum 17 through the weft brake 20 to the main nozzle 21 for weft insertion is unwound from the drum 17 and inserted by the main nozzle 21 performing an injection operation.

  In the weft brake 20, a pair of fixed guides 20a, 20a for guiding the weft 14 are disposed apart from each other, and a movable guide 20b for bending the weft 14 is provided between the fixed guides 20a, 20a so as to be able to advance and retreat. The movable guide 20b is driven back and forth by the actuator 20c. In the weft brake 20, the actuator 20 c operates at the end of weft insertion and the movable guide 20 b advances between the fixed guides 20 a and 20 a, thereby bending the weft 14 and applying a braking force to the weft 14. This prevents the weft 14 from being broken due to the weft 14 being restrained by the engagement pin 18 at the end of the weft insertion.

  The main nozzle 21 corresponding to the selected weft 14 starts jetting of pressurized air toward the opening 25 of the warp 24 at the set weft insertion start timing, and continues jetting for the set jetting period. Thus, the weft 14 having a predetermined length is inserted into the opening 25. By this weft insertion operation, the weft 14 flies along the weft flying path in the opening 25. The pressure air is supplied from a pressure air source 35, adjusted to an appropriate air pressure for weft insertion by a pressure regulator 36, and then supplied to the main nozzle 21 via an electromagnetic on-off valve 37. The electromagnetic open / close valve 37 operates based on the weft selection order determined in the weft insertion pattern under the control of the weft insertion control unit 44.

  As described above, the weft insertion device 11 shown in FIG. 1 is compatible with four-color weft insertion, but in the case of two or more colors weft insertion, the yarn feeder 13, the length measuring storage device 15, the main nozzle 21 and the like are The weft inserting operation is performed according to the weft selection order set according to the number of multicolors (the number of wefts) and set in the weft insertion pattern.

  In the process in which the wefts 14 inserted in the weft travel along the travel path in the opening 25, the plurality of groups of sub-nozzles 22 perform simultaneous injection of the compressed air toward the travel direction of the weft 14 along the weft travel path. Relay injection is performed to urge the flying weft 14 in the weft insertion direction. The pressure air is supplied from the pressure air source 35, adjusted to an appropriate air pressure by the pressure regulator 38, and then supplied to the sub nozzles 22 of each group through the electromagnetic on-off valves 39 corresponding to the groups. Each electromagnetic on-off valve 39 is under the control of the weft insertion control unit 44 at the time of weft insertion, supplies pressurized air to the sub nozzles 22 of the corresponding group at the set timing, and causes the sub nozzles 22 to inject the pressure air. The flying weft 14 is urged in the weft insertion direction.

  The pressure regulator 38 for the sub nozzle described above may be a pressure regulating valve. However, since there is a problem in terms of responsiveness, the pressure regulator 38 uses a switching valve to set a plurality of paths according to the number of weft insertion series each having a pressure regulating valve or the number of pressure values to be switched. It is preferable to selectively switch.

  When the weft yarn 14 is normally inserted by the injection operation of the main nozzle 21 and the sub nozzles 22 of the plurality of groups, the weft yarn 14 is beaten on the pre-weaving 29 of the woven fabric 28 by the hammering motion of the collar 27, After being woven into the woven fabric 28, it is cut by the yarn feeding cutter 30 on the weft insertion side, and is cut off from the weft 14 inside the main nozzle 21.

  Whether or not weft insertion has been performed normally is determined by the first weft detection device (feeler) 31 and its sensor (feeler head) 33 (hereinafter also referred to as “first sensor”) and the second weft detection. It is detected by a device (feeler) 32 and its sensor (feeler head) 34 (hereinafter also referred to as “second sensor”). The sensor 33 of the first weft detection device 31 faces the weft runway in the vicinity of the woven end portion of the woven fabric 28 on the side opposite to the weft insertion side, and is provided at a position where the weft 14 inserted normally can reach. Therefore, the front end of the weft 14 that is normally inserted is detected. This detection is performed by comparing the level of the detection signal generated in the sensor 33 and the reference signal level within the normal arrival time (set detection period) of the weft 14. Therefore, according to the sensor 33 of the first weft detection device 31, a weft insertion failure in which the tip of the weft 14 does not reach the position of the first sensor 33 despite the weft insertion (show topic, ben topic, etc.) Is detected. The detection period is normally set on the rotation angle of the main shaft 40.

  In the detection period, when the first sensor 33 detects the arrival of the weft yarn 14, it generates an output signal corresponding to the arrival. At that time, the first weft detection device 31 generates a yarn signal S1 corresponding to normal weft insertion based on the output signal from the first sensor 33, and this yarn signal S1 is subjected to main control in the loom control device 42. Send to device 42a. The main control device 42a continues the operation (weaving) of the loom on condition that the yarn signal S1 corresponding to normal weft insertion exists.

  In the detection period, when the yarn signal S1 is not generated, that is, when the weft insertion failure has occurred and the first sensor 33 cannot detect the arrival of the weft 14, the first weft detection device 31. Determines that the weft insertion is abnormal, outputs a weft stop signal (also referred to as “first weft stop signal”) S2, and sends this weft stop signal S2 to the main controller 42a.

  When receiving the weft stop signal S2, the main control device 42a immediately executes stop control to stop the loom at a predetermined angle.

  The sensor 34 of the second weft detection device 32 is located further away from the first sensor 33 in the weft insertion direction than the first sensor 33 on the opposite weft insertion side, that is, the weft thread that has been normally inserted. It faces the weft flight path at a position where 14 does not reach, and is provided to detect a weft insertion failure such as blowout of the weft 14 or a long pick. This detection is performed by comparing the level of the detection signal generated in the second sensor 34 with the level of the reference signal at the abnormal arrival time (arrival angle) of the weft 14 within the detection period. The detection period is normally set on the rotation angle of the main shaft 40. During this detection period, when the second weft detection device 32 receives the output signal from the second sensor 34, the second weft detection device 32 determines that the weft insertion is abnormal, and a weft stop signal ("second weft stop signal"). (S3) is generated, and the weft stop signal S3 is sent to the main controller 42a.

  When receiving the second weft stop signal S3, the main control device 42a immediately stops the loom at a predetermined angle in the same manner as when the first weft stop signal S2 is received.

  The loom control device 42 controls the loom in a state synchronized with the rotation of the main shaft 40 of the loom and performs other necessary control, and the main control device 42a and the weft insertion control device 43 (the weft insertion control unit 44). And the weft selection signal generator 45). In order to detect the rotation angle θ of the main shaft 40, an encoder 41 is connected to the main shaft 40, and during the weaving, the encoder 41 generates a signal of the rotation angle θ of the main shaft 40, and outputs this signal to the main controller 42a, and This is sent to the weft insertion control unit 44 and the weft selection signal generation unit 45 of the weft insertion control device 43.

  The main control device 42a performs control of the main movement of the loom and control at the time of stopping based on the signal of the rotation angle θ of the main shaft 40. The weft selection signal generator 45 of the weft insertion control device 43 detects the amount of rotation of the main shaft 40 from the rotation angle θ, selects the weft 14 based on the weft selection order preset in the weft insertion pattern, and selects that A weft selection signal S8 corresponding to the weft 14 thus generated is generated, and this weft selection signal S8 is sent to the weft insertion control unit 44. The weft insertion control unit 44 selects an appropriate rotation angle θ according to control values set for the operations of the weft insertion series length measuring and storage device 15 corresponding to the selected weft 14, the weft brake 20, the main nozzle 21, the sub nozzle 22, and the like. And the weft insertion operation of the weft 14 selected by the corresponding weft insertion sequence is executed.

  In the description so far, the weft insertion pattern has been set as the weft selection order. To be precise, the weft insertion pattern has a weft insertion sequence ("selection number assigned to the weft insertion sequence"). The selection order is set.

  The “weft insertion series” refers to a group to which a plurality of weft insertion related devices that operate to realize one weft insertion in cooperation. The “weft insertion-related device” is a device that is involved in the weft insertion of the weft 14 drawn from the yarn supply body 13 and is an apparatus that exists downstream from the yarn supply body 13. The weft-related devices include a length measuring storage device 15, a weft brake 20, a main nozzle 21, a sub nozzle 22, and first and second weft feelers 31, 32. However, among these, the sub nozzle 22, the first and second weft feelers 31, 32 are used in common in each weft insertion series.

  The loom control device 42 described above is configured as a combination of functional blocks. The loom control device 42 may be realized by combining devices composed of blocks, or by installing predetermined software on a computer and executing the software, the computer's input / output means, storage means, arithmetic control It is also possible to configure each block in which the means and software cooperate and to realize the block.

  Further, a setting display device 46 as a setting device is provided so as to be capable of bidirectional communication in order to exchange data of weaving conditions and the like with the main control device 42a and the weft insertion control device 43.

  The setting display device 46 includes an input display 47, a port 48, a memory 49 as a storage unit, and a CPU 50 as a processing unit. The port 48 receives data (including various signals) from the input display 47, the processing unit 50, and the loom control device 42, and transmits and receives data among them.

  The memory 49 is rewritable. The memory 49 stores a program for controlling the touch panel type input display 47 and other necessary software, as well as weft insertion condition data and other necessary data. The weft insertion condition data is transferred to the weft insertion control unit 44 and the weft selection signal generation unit 45 via the CPU 50 and stored (set) by an operation on the setting display device 46.

  The input display 47 is a display device, and a part of the display screen also serves as a touch panel type input device. By a touch operation on a display key (display button) on the display screen, a display request, various commands, and latitudes are displayed. It is possible to change the insertion conditions.

  The CPU 50, a so-called microprocessor, controls input / output at the port 48 according to predetermined software stored in the memory 49, controls the input display 47, and responds to a screen display request from the input display 47. The predetermined data is read from 49 and the requested display screen is displayed on the input display 47.

  FIG. 2 shows an example of a display screen displayed on the input display 47. The display screen 51 of FIG. 2 is a so-called touch panel type, and displays the display contents for changing the weft insertion conditions on one screen. The display contents are display keys 52 to 61 for the operator to select (touch operation). There are display keys (display buttons) indicating items of weft insertion series and weft insertion conditions, execution, and close. Hereinafter, each display key will be described in detail.

  The weft insertion series display key 52 is displayed in the upper part of the display screen 51, and a selection number 52b assigned to each weft insertion series is displayed in a form attached to the yarn feeder mark 52c. In the illustrated example, the selection number 52b is displayed in the yarn feeder mark 52c. Further, the display keys 52 of the weft insertion series are collectively displayed for the number of colors of the weft yarns 14 that can be inserted by this multicolor weft insertion loom. Two sets of such display keys 52a of weft insertion series are provided apart from each other on the left and right. The two sets of display keys 52a for the weft insertion series can select the display keys 52 for the weft insertion series one by one from each group, and two display keys 52 for the two weft insertion series corresponding to the wefts 14 to be replaced. Select from a pair.

  The display key group 52a of each set of weft insertion series can correspond to the weft insertion device 11 capable of inserting wefts 14 of up to eight colors (eight) in the illustrated example, and has a form of 2 rows × 4 columns. The weft insertion display key 52 is displayed with selection numbers 1 to 8 in order. Here, in order to insert a weft in four weft insertion series, the ones with selection numbers 1 to 4 among the display keys 52 of the weft insertion series are clearly displayed to indicate that they can be selected. In addition, the display key 52 of the weft insertion series selected by the operator in order to change the weft insertion conditions is provided with a display (smugging, hatching, etc.) to distinguish it from those not selected. On the other hand, for the remaining four display keys of the weft insertion series (those with selection numbers 5 to 8), the brightness is displayed lightly, indicating that selection is impossible.

  Display keys 53 to 59 for each item of the weft insertion condition are displayed in the middle of the display screen 51, and weft insertion to be replaced with a control value (control value for controlling a weft insertion related device belonging to a weft insertion series). It is divided into related devices and weft insertion patterns. In the example shown in the drawing, the weft insertion-related devices whose control values are to be replaced are the main nozzle 21 and the sub nozzle 22, the weft brake 20 (display key: WBS55), the length measuring storage device 15 (display key: feeder 56), the first And second weft detection devices 31, 32 (display key: feeler 57). However, with respect to the main nozzle 21 and the sub nozzle 22, electromagnetic on-off valves 37 and 39 (display key: main / sub 53) for controlling the injection timing, and pressure regulators 36 and 38 (display key: pressure) for adjusting respective pressures. 54) is a target for replacement of control values.

  The control values of each weft insertion-related device displayed by the display key are as follows. In the case of the main / sub 53, the control value is the injection timing (= ON / OFF timing of the electromagnetic on-off valves 37, 39). In the case of the pressure 54, the control value is the injection pressure of the main / sub nozzles 21 and 22 (= adjusted amounts by the pressure regulators 36 and 38). In the case of WBS 55, the control value is an operation mode of the actuator 20c for moving the movable guide 20b back and forth. In the case of the feeder 56, the control value is an operation mode (operation amount (= winding amount), rotation speed, acceleration / deceleration, etc.) of a drive motor for driving the yarn winding arm 16 in the length measuring storage device 15. In the case of the feeler 57, the control value is a control gain for yarn signal processing in the first and second weft detection devices 31 and 32, a threshold value (reference signal level) for determining whether weft insertion is normal or abnormal, and the like. These control values are set in the weft insertion control unit 44.

  In this embodiment, since the control value is replaced while the selection number assigned to the weft insertion series is fixed, it is also necessary to replace the selection number in the weft insertion pattern. Accordingly, in the illustrated example, the selection number of the weft insertion pattern (display key: pattern 58) is also a replacement target. The weft insertion pattern is set in the weft selection signal generator 45.

  Selection of the weft insertion related device and the weft insertion pattern to be replaced is performed by touching the display keys corresponding to each. However, the selection here is a provisional selection.

  In addition, in the example shown in the figure, as a display key for each item of the weft insertion condition, these key displays are collectively selected below the key display of the weft insertion related device and the weft insertion pattern (display key). : All 59) are provided. When the display key 59 is touched, all six items (5 weft insertion related devices and weft insertion patterns) displayed on the upper side are selected.

  An execution display key (display: execution 60) is displayed in the lower part of the display screen 51. When this display key 60 is touched, the selection (provisional selection) for the display key 52 of the weft insertion series and the selection (provisional selection) for each item of the weft insertion condition 53 to 59 are effective. (Confirm), and the weft insertion conditions are replaced for the two weft insertion series. Then, according to the selection state at that time, the control value is switched and set in the predetermined storage area of the weft insertion control unit 44 for the selection numbers of the two selected weft insertion series, or the weft selection signal is generated. In the predetermined storage area of the unit 45, the selection numbers of the two selected weft insertion sequences are replaced and set in the weft insertion pattern.

  A close display key (display: close 61) is displayed at the bottom of the display screen 51. When this display key 61 is selected, the display screen 51 for changing the weft insertion condition is closed and another display screen is displayed. For example, this is a display screen for numerically inputting each item of weft insertion condition. Here, each item of weft insertion condition can be input.

  FIG. 3 shows the display contents when the weaving pattern set in the weft selection signal generator 45 via the setting display device 46 is displayed on the display screen of the input display 47 of the setting display device 46. In this display content, numbers are arranged vertically below the characters “color”, which corresponds to the weft insertion pattern P (also referred to as “weft selection pattern”). Color means herein a selection number assigned to a weft insertion series. In the illustrated example, the weft sequences to which the selection numbers are assigned operate in the order of selection numbers 1, 2, 3, and 4 from the bottom to the top. It should be noted that the color usually means each weft 14 to be wefted in a multicolor weft loom.

  Table 1 shows that when we replace the correspondence between two wefts 14 and the two weft insertion series in which these wefts 14 are inserted, weft insertion related devices belonging to each weft insertion series achieve normal weft insertion. This is to understand which one of the weft insertion conditions (control value, weft insertion pattern, and selection number) needs to be replaced.

  In the example of Table 1, before the replacement, the weft insertion line 1 (predetermined weft insertion-related device belonging to the weft insertion line 1) is used for weft insertion (= weft) C1 in the weft insertion line 1 The weft thread C1 is passed through and selection number 1 is assigned, and a control value for C1 is preset in a form dependent on selection number 1. A weft thread C2 is passed through the weft insertion series 2 and a selection number 2 is assigned, and a control value for C2 is preset in a form dependent on the selection number 2. Similarly, the weft insertion series 3 and 4 are preset in the same manner. The control values for C1 to C4 are control values of all the weft insertion related devices in each weft insertion series. Further, weft insertion patterns are set in the selection order of selection numbers 1, 2, 3, and 4, and the wefts are inserted in the order of wefts C1 to C4.

  In the four-color weft insertion device 11 that has been set in advance before replacement, the weft insertion line 2 is passed through the weft insertion line 2 in order to change the correspondence between the weft insertion lines C2 and C3 and the weft insertion line. The series 3 is replaced by passing the weft C2. In this case, if the setting of the weft insertion series 2 and the weft insertion series 3 is not changed, in the weft insertion series 2 in which the selection number 2 is set, the weft C3 is inserted with the control value for C2, and the selection number 3 is set. In the weft insertion series 3, the weft C2 is weft-inserted with the control value for C3, which may cause a weft insertion failure. Moreover, since the weft insertion pattern remains the same, the wefts C1, C3, C2, and C4 are inserted in this order, resulting in a pattern defect. Therefore, it is necessary to change the setting.

  The first example after replacement is a replacement method when the selection number set for each weft insertion series is fixed. In this case, it is necessary to exchange the C3 control value and the C2 control value so that the selection number 2 corresponds to the C3 control value and the selection number 3 corresponds to the C2 control value. Also, the selection numbers of the weft insertion patterns need to be exchanged, and the weft insertion patterns are set in the selection order of selection numbers 1, 3, 2, and 4, and the wefts C1 to C4 are inserted in this order.

  The second example after the replacement is a method of switching the selection number 2 assigned to the weft insertion series 2 and the selection number 3 assigned to the weft insertion series 3. Since the control value is dependent on the selection number, the control value for C3 subordinate to the selection number 3 is automatically set in the weft insertion sequence 2 simply by exchanging the selection numbers 2 and 3, and the weft insertion is performed. For the series 3, the control value C2 subordinate to the selection number 2 is automatically set. In this case, the weft insertion pattern may remain the same.

  A method for setting the weft insertion conditions in the above-described multicolor weft insertion loom will be described based on the following assumptions. The multi-color weft insertion loom is a four-color air jet loom that wefts are drawn in four weft insertion series corresponding to each yarn supply body. The wefts used are the wefts C1, C2, C3, C4, and the selection numbers preset for the weft insertion sequences corresponding to the wefts are 1, 2, 3, 4. In the weft insertion control unit 44, the control value of each weft insertion related device for weft insertion of each weft C1 to C4 is associated with the selection number assigned to the weft insertion series to which each weft insertion related device belongs in advance. Is set. As described above, the selection number of the weft insertion series when the correspondence between the two wefts C2, C3 and the two weft insertion series 2, 3 in which the wefts C2, C3 are separately inserted is changed. An example is given in which the control values corresponding to the weft insertion series are replaced while 2 and 3 are fixed.

  First, the operator switches the position (position relative to the yarn feeder stand 12) between the yarn feeder 13 of one weft C2 and the yarn feeder 13 of the other weft C3. Subsequently, the operator removes both the wefts C2 and C3 from the length measuring and storage devices 15 of the corresponding weft insertion series 2 and 3, the weft brake 20, the main nozzle 21 and the like, and removes one weft C2 to the other. The weft insertion series 3 length measurement storage device 15, the weft brake 20, the main nozzle 21 and the like are exchanged, and the other weft C3 is exchanged to one weft insertion series 2 length measurement storage device 15 and the like.

  Next, the replacement operation of the weft insertion conditions of each weft insertion related apparatus set in correspondence with each selection number is performed according to the following procedures (steps) (1) to (4).

  (1) The display screen for replacement shown in FIG. 2 is displayed on the input display 47 of the setting display device 46.

  (2) Select the weft insertion series 2 and 3 corresponding to the wefts C2 and C3 whose correspondences are changed. Specifically, the display keys that are clearly shown among the yarn feeder marks shown in the upper part of the display screen 51 correspond to the weft insertion series 1 to 4. By touching the display key 52 corresponding to the weft insertion series to be selected one by one from the two display key groups 52a, 52a in which the display keys of the weft insertion series are gathered, a desired weft insertion series (2 in the figure) is displayed. And 3) are selected (provisionally selected). When the operator touches, a signal for temporary selection by touch is output from the input display 47 to the CPU 50 via the port 48.

  (3) Select the replacement of the selection number in the weft insertion pattern, and select the weft insertion-related device whose control value is to be replaced. Specifically, the display keys 53 to 57 corresponding to the respective weft insertion related devices in the middle stage of the display screen 51 are touched to make a selection state. The selection number in the weft insertion pattern is changed by touching the display key of the pattern 58 on the display screen 51. Further, the display screen 51 in the illustrated example includes an “all” display key 59. By selecting this, replacement of the selection numbers in the weft insertion related devices and weft insertion patterns to be replaced is selected at once. In the following description, it is assumed that “all” is touched. Similarly, a temporary selection signal by touch is output from the input display 47 to the CPU 50 via the port 48.

  (4) Perform an execution operation to validate the selection operation so far, generate a replacement command signal by the execution operation, and set the control value set in the weft insertion control unit 44 and the weft selection signal generation unit 45 The setting display device 46 performs replacement for the selection number of the weft insertion pattern. Specifically, by touching the “execute” display key 60 shown in the lower part of the display screen 51, a replacement command signal is output from the input display 47 to the CPU 50 via the port 48. The CPU 50 to which the replacement command signal is input, selects the provisional selection signal (selection for the weft insertion series display key 52 (temporary selection) and selection of the display keys 53 to 59 for the weft insertion condition items). (Tentative selection)) is determined to be valid (confirmed), and the weft insertion conditions are automatically replaced for the two weft insertion sequences. The selection until the execution display key 60 is selected corresponds to the first step in the present invention, and the subsequent steps correspond to the second step.

  By performing the replacement as described above, each weft insertion-related device in the weft insertion series 2 is driven according to the control value for controlling the weft C3 at the timing of weft insertion of the weft C3. Each of the weft insertion-related devices is driven according to a control value for controlling the weft C2 at the timing when the weft C2 is inserted.

  The present invention is not limited to the above examples. For example, in the above-described example, in (3), the operator performs the operation of selecting the replacement of the selection number in the weft insertion pattern and selecting the weft insertion-related device whose control value is to be replaced. The same replacement may be performed only by 1), (2), and (4). In this case, it is assumed that the selection number in the weft insertion pattern and the weft insertion related device whose control values are to be replaced are set in advance as replacement targets.

  In the above example, the selection number of the weft insertion pattern and the control value of the weft insertion related device are adopted as the replacement target. However, the selection number may be adopted. In this case, it is assumed that the selection number is set as a replacement target in advance.

  The input device of the input display 47 is not a touch panel type, and may be another input device such as a keyboard.
