Description

  The present invention relates to a method for setting a control value of a weft insertion device in a multicolor weft insertion loom including a weft insertion device having a plurality of weft insertion sequences.

  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. In the present application, a set to which these weft insertion related devices belong is called a “weft insertion series”.

  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, a control value as a weft insertion condition is preset in the form corresponding to the selection number to the weft insertion controller by the setting device. The “control value” here 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 at the weft insertion nozzle And the operation timing and operation timing of the yarn winding arm driving motor in the length measuring storage device.

  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 unit, and weft insertion is performed in cooperation.

  By the way, setting of weft insertion conditions to the weft insertion control unit or the like is conventionally performed by transferring control values from an external storage medium such as a memory card storing the weft insertion conditions or a host computer connected to the loom. It is done in As an example of such a conventional technique, Patent Document 1 described later discloses a multicolor weft insertion loom entitled “setting method of setting values in a loom”. In this document, after a worker manually inputs a weft insertion condition (control value) for one weft insertion series (selection number), a control value is set for another weft insertion series using the copy function. It is disclosed.

  Further, conventionally, when weaving conditions including the weft insertion conditions of a previously woven fabric are stored in a storage medium, and the same woven fabric is then woven, the entire weaving conditions are read and set as they are. Sometimes. For example, when weaving different woven fabrics, there is a case where it is desired to set only a part of the weft insertion conditions in the previously used weaving conditions in the weft insertion control unit. In other words, one of a plurality of wefts to be inserted (hereinafter referred to as “weft A”) may be inserted under the same conditions (control values) as the same weft A in the previous weaving. In this case, there is a case where only the control value for weft insertion of the weft A is read from the weft insertion conditions used in the previous weaving and stored in the storage medium, and set in the weft insertion control unit. .

  Incidentally, as described above, the control value in the weft insertion condition set in the weft insertion control unit of the loom is set in correspondence with the selection number, and accordingly, the latitude stored in the storage medium or the like is set. The insertion condition is also set in such a manner that the control value and the selection number are associated with each other. Therefore, if the weft insertion sequence (selection number) for weft insertion of the weft A is the same between the current weaving and the previous weaving, only the control value can be read and set as it is from the storage medium or the like. Although it is possible, if the weft insertion sequence (selection number) for weft insertion of the weft A is different between the current weaving and the previous weaving, simply as in the case where the above selection numbers are the same It cannot be read and set, and the setting work becomes troublesome.

  Specifically, if weft A was inserted in the weft insertion series of selection number 1 in the previous weaving, the control value for weft insertion of weft A is stored in a storage medium or the like corresponding to selection number 1 Yes. Accordingly, when it is read as it is and set in the weft insertion control unit, the control value for inserting the weft A is set as the control value of each weft insertion related device in the weft insertion series of selection number 1. For this reason, in the present weaving, when weft A is inserted in a weft insertion sequence of selection number 3 different from the previous one, setting by reading from a storage medium or the like cannot be performed. For example, after reading from a storage medium or the like and setting it as it is in the weft insertion control unit, the control value is further set to the latitude of selection number 3 using the copy function of Patent Document 1 described above. It is necessary to perform an operation of setting the control value for the weft insertion sequence of selection number 1 after setting the insertion sequence.

JP 2006-70410 A

  An object of the present invention is to provide a specific weft insertion stored in a storage medium when a control value as a weft insertion condition is stored in the storage medium in a form corresponding to a selection number in a multicolor weft insertion loom. The condition control value can be easily set by the operator in a form corresponding to an arbitrary selection number for the weft insertion control unit.

  The present invention sets a control value for controlling the operation of a weft insertion device comprising two or more weft insertion sequences composed of a plurality of weft insertion related devices that operate at the time of weft insertion, and the weft insertion related devices belonging to each weft insertion sequence And a weft insertion control unit in which a control value is preset as a weft insertion condition in a form corresponding to a selection number assigned to each weft insertion series, and the operation of each weft insertion related device in the weft insertion series A multi-color weft insertion loom including a weft insertion control unit that performs weft insertion by each weft insertion related device by controlling according to the control value is assumed.

  And the setting method of the weft insertion condition in the multi-color weft insertion loom is the method of the weft insertion related apparatus which is the setting target among the control values corresponding to the selection number selected from the weft insertion conditions stored in the storage device. Weft insertion control as a control value for a weft insertion-related device to be set in a step of reading a control value and the control value read in the step upon generation of a setting command signal in a weft insertion series of a specified selection number The setting unit executes the step of setting the unit.

  Moreover, it does not ask | require whether the control value of the weft insertion related apparatus which is a setting object is preset. In order to make it easy for an operator to grasp such a setting target, it is desirable to do the following. In other words, such a weft insertion condition setting method is a control value setting target among the weft insertion related devices belonging to the weft insertion series before the step of reading the control value of the weft insertion related device which is the setting target. The operator selects the items individually or collectively.

  According to the weft insertion condition setting method of the present invention, the control value of each weft insertion related device stored in correspondence with the selection number in the storage device is sent to the weft insertion related device belonging to the weft insertion sequence having a different selection number. The control value can be easily set, and the time and labor for changing the weft insertion condition setting can be greatly reduced.

  Also, according to the weft insertion condition setting method of the present invention, among the weft insertion related devices belonging to the weft insertion series, devices for which control values are to be set are set in advance so that they can be selected from them. This facilitates the setting work. And in the selection, by making it possible to individually select each weft insertion related device to be set, it becomes possible to set only necessary control values. However, since there are many cases where the setting is basically performed in a lump, it is possible to select the weft insertion related devices to be set in a lump with the selection function as described above. In this case, 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 displayed on a setting display apparatus in order to set the weft insertion conditions of a weft insertion control part.

  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 is actually provided with four weft insertion sequences. To do. 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. Preferably switched selectively

  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 (hereinafter 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 determines a weft stop signal (hereinafter referred to as "second weft stop"). It is also referred to as a “signal”.) S3 is generated, and this 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 in 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 measurement storage device 15, a weft brake 20, a main nozzle 21, a sub nozzle 22, and first and second weft detection devices 31, 32. However, among these, the sub nozzle 22, the first and second weft detection devices 31 and 32 are commonly used in each weft insertion series.

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 an internal storage unit, a CPU 50 as a processing unit, and a card reader 51 for inserting a memory card 52 as a storage device (external storage unit). is doing. The port 48 receives data (including various signals) from the input display 47, the CPU 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 and data.

  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 memory card 52 and the requested display screen is displayed on the input display 47.

  In the memory card 52, among the weft insertion conditions used in the past weaving, the control values of the weft insertion related devices belonging to the weft insertion series used in the current weaving are selected to be assigned to each weft insertion series It is stored in a form associated with (associated with) the number. The weft insertion conditions stored in the memory card 52 are transferred to the memory 49 and the weft insertion control unit 44 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 configured to enable setting of entry conditions.

  FIG. 2 shows an example of a display screen displayed on the input display 47. The display screen 53 of FIG. 2 is a so-called touch panel type, and displays the display content for setting the weft insertion condition of the weft insertion control unit 44 on one screen. The display contents are display keys 54 to 62 for the operator to select and specify (touch operation). The display key (display button) includes a transfer source selection number, a transfer destination selection number, and a selection number (weft insertion series) designated as the transfer destination for each item (hereinafter referred to as “control value”) for which a control value is to be set. ")", And some items indicate execution and close. Hereinafter, each display key will be described in detail. The transfer source referred to here is the memory card 52 in the illustrated example, and the transfer source selection number is a selection number stored in the memory card 52 in association with the control value, and is used for past weaving. Is a selection number assigned to each weft insertion series in which the control value is used. The transfer destination is a weft insertion control unit 44 in the loom to which a control value is set, and the transfer destination selection number is a selection number assigned to each weft insertion sequence in the loom. This is a selection number set in the control unit 44.

  A plurality of transfer source and transfer destination selection number display keys 54 and 63 are collected to form a transfer source and transfer destination selection number display key group 54a and 63a. The display key groups 54 a and 63 a for the transfer source and transfer destination selection numbers are arranged in the upper part of the display screen 53. In FIG. 2, the display key group 54a of the transfer source selection number is displayed on the upper right side of the display screen 53, and “card side” is displayed in the vicinity thereof. On the other hand, the display key group 63a of the transfer source selection number is displayed on the upper left side of the display screen 53, and “setting side” is displayed in the vicinity thereof. One display key 54 can be selected (temporarily selected) from the display key group 54a of the transfer source selection number, and one display key 63 is specified (temporary specification) from the display key group 63a of the transfer destination selection number. It can be done.

  The transfer source selection number display key 54 is displayed in a form in which a yarn selection mark 54b and a different selection number 54c are associated with each other. This selection number 54 c is assigned (corresponding) to the control value of the weft insertion condition stored in the memory card 52.

  On the other hand, the transfer destination selection number display key 63 is also displayed in association with a selection number 63c different from the yarn feeder mark 63b. This selection number 63c is assigned to the weft insertion series controlled by the weft insertion control unit 44 of this multicolor weft insertion loom, and is assigned in a form corresponding to the control value of the weft insertion condition to be set. It is a thing.

  In FIG. 2, the display key groups 54a and 63a of the transfer source and transfer destination selection numbers are each composed of eight display keys 54 and 63 arranged in a form of 2 rows × 4 columns. That is, in the illustrated example, unlike the number of weft insertion series actually provided in the loom, weft insertion of wefts 14 of a maximum of eight colors (eight) is displayed so that it can be shared by various looms. This is compatible with possible weft insertion devices 11.

  In addition, the display screen clearly indicates that the transfer source selection number display keys 54 with the selection numbers 1 to 6 can be selected. In other words, this example shows that the weft insertion conditions stored in the memory card 52 are those used in the six-color weft insertion device 11. In addition, as for the transfer destination selection number display key 63, those with selection numbers 1 to 4 are clearly displayed, indicating that they can be designated. In other words, the loom including the weft insertion control unit 44 as a transfer destination includes the weft insertion device 11 including four weft insertion sequences. On the other hand, with respect to those with selection numbers 7 and 8 among the display key 54 of the transfer source selection number and those with selection numbers 5 to 8 of the display key 63 with the transfer destination selection number, the lightness Are dimmed to indicate that they cannot be selected or specified. Further, on the display screen, the display keys 54 and 63 of the transfer source and transfer destination selection numbers selected or designated by the operator are provided with displays (smudged, hatched, etc.) that are distinguished from those not selected or designated. ing.

  Display keys 55 to 60 for each item of the control value are displayed in the middle of the display screen 53, and are related to the weft insertion target for setting the control value (control value for controlling the weft insertion related device belonging to the weft insertion series). The device is shown. In the example shown in the figure, the weft insertion-related devices for which the control values are set are the main nozzle 21 and the sub nozzle 22, the weft brake 20 (display key: WBS 57), the length measuring storage device 15 (display key: feeder 58), the first And second weft detection devices 31, 32 (display key: feeler 59). However, with respect to the main nozzle 21 and the sub nozzle 22, electromagnetic on-off valves 37 and 39 (display key: main / sub 55) for controlling the injection timing, and pressure regulators 36 and 38 (display key: pressure) for adjusting respective pressures. 56) is a control value setting target.

  The control values of each weft insertion-related device displayed by the display key are as follows. In the case of the main / sub 55, the control value is the injection timing (= ON / OFF timing of the electromagnetic on-off valves 37, 39). In the case of the pressure 56, 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 the WBS 57, 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 58, the control value is an operation mode (operation amount (= winding amount), rotational 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 59, 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.

  Selection of the weft insertion related device to be set is performed by touching the display key 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 control value, there is one that collectively selects these key displays (display keys: all 60) below the key display of the above-described weft insertion related device. Is provided. When the display key 60 is touched, all the five items (the five weft insertion related devices) displayed on the upper side are selected.

  An execution display key (display: execution 61) is displayed in the lower part of the display screen 53. When this display key 61 is selected, selection and designation (temporary selection and provisional designation) for the display keys 54 and 63 of the transfer source and transfer destination selection numbers and the display key 55 for each item of control value performed before that. The selection (provisional selection) for ˜60 becomes valid (confirmed). Then, a control value corresponding to the selected transfer source selection number is read from the memory card 52 into the setting display device 46 as a control value for the selected weft insertion related device, and is set to the designated transfer destination selection number. The weft insertion control unit 44 is set in a corresponding manner.

  A close display key (display: close 62) is displayed in the lower part of the display screen 53. When this display key 62 is selected, the weft insertion condition (control value) of the weft insertion control unit 44 is used while using the memory card 52. The display screen 53 for setting is closed and another display screen is displayed. For example, it is a display screen for numerically inputting each item of the control value. Here, each item of the control value corresponding to the selection number can be input.

  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-injection loom that wefts 14 that are drawn from the four yarn supply bodies 13 are inserted in four weft insertion sequences corresponding to the respective yarn supply bodies 13. 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. (Hereinafter, the weft insertion series of selection numbers 1, 2, 3, 4 are also referred to as weft insertion series 1, 2, 3, 4) And the weft insertion control unit 44 includes each weft C1-C4. It is assumed that the control value of each weft insertion related device for inserting the weft is set in association with the selection numbers 1, 2, 3, 4 assigned to the weft insertion series to which each weft insertion related device belongs. Further, as described above, it is assumed that the control value is stored in the memory card 52 in association with the selection number (1 to 6) among the weft insertion conditions used for past weaving.

  In this example, for the four weft insertion sequences used in this weaving, the setting display device 46 reads the control value for each weft insertion related device in one of them from the memory card 52, and the weft insertion control unit 44 (however, the transfer destination selection number corresponding to the control value set in the weft insertion control unit 44 is different from the transfer source selection number corresponding to the control value read from the memory card 52). To do.)

  Based on the above assumption, the control value stored in correspondence with the selection number 3 is read from the weft insertion conditions stored in the memory card 52, and is used as the control value of each weft insertion related device in the weft insertion sequence 2. The case of setting in the weft insertion control unit 44 will be described in accordance with the following steps (1) to (6). The control value for each weft insertion related device belonging to other than the weft insertion series 2 (selection number 2) is, for example, read a weft insertion condition stored in another memory card or input by an operator ( It is set in the weft insertion control unit 44 by numerical input). (When reading from a memory card, for the weft insertion sequence 2 in the weft insertion control unit 44, the control value stored in correspondence with the selection number 2 is set for that card.

  (1) The memory card 52 in which a plurality of weft insertion conditions are stored is inserted into the card reader 51 in the setting display device 46.

  (2) The input display 47 of the setting display device 46 is operated, and the weft insertion condition (control value) of the weft insertion control unit 44 while using the memory card 52 as shown in FIG. A display screen 53 for setting is displayed.

  (3) The selection number 2 of the weft insertion series to be set in the weft insertion control unit 44 is designated. Specifically, from the display key group 63a of the transfer destination selection number displayed on the left side of the upper portion of the display screen 53, the selection number of the weft insertion series to be set (in the example shown, “2”). The operator touches the display key) and the selection number is designated (temporarily designated). Then, a temporarily designated signal by the touch is output from the input display 47 to the CPU 50 via the port 48.

  (4) Select selection number 3 corresponding to the control value to be read from the memory card 52. Specifically, the selection number corresponding to the control value to be read out of the display key group 54a of the transfer source selection number displayed on the upper right side of the display screen 53 (in the example shown, “3” is displayed). The operator touches the key), and the selection number is selected (temporarily selected). Then, a temporary selection signal by the touch is output from the input display 47 to the CPU 50 via the port 48.

  (5) A weft insertion related device controlled by a control value to be set is selected. Specifically, the operator touches the display keys 55-60 of the control value items corresponding to the respective weft insertion-related devices in the middle of the display screen 53, and the weft insertion-related device is selected. Note that, on the display screen 53 in the illustrated example, by touching the “all” display key 60, all the weft insertion related devices belonging to the selected weft insertion series (selection number) are selected at once. It becomes. In the following description, it is assumed that all are selected. Then, a temporary selection signal by the touch is output from the input display 47 to the CPU 50 via the port 48.

  (6) An execution operation that validates the selection operation and the designation operation so far is performed, a setting command signal is generated by the execution operation, and the control value to be set for the selected selection number 3 is read from the memory card 52. Thus, the control value corresponding to the selection number 2 is set in the weft insertion control unit 44. Specifically, when the operator touches the “execution” display key 61 displayed in the lower part of the display screen 53, a setting command signal by the touch is output from the input display 47 to the CPU 50 via the port 48. The The CPU 50 to which the setting command signal is input determines that the provisional selection and provisional designation signal input before that is valid (confirmed). The setting command signal also serves as a read command signal, whereby the control value is read from the memory card 52 to the CPU 50 and then set to the weft insertion control unit 44.

  The present invention is not limited to the above examples. For example, in the above-described example, the weft insertion related device controlled by the control value to be set is selected in step (5), but this is omitted, and (1), (2), (3) , (4), (6) may be used for the same setting. In this case, it is assumed that a device for reading a control value among the weft insertion related devices is set in the program as a setting target in advance.

  In the above example, the setting is performed in steps (1) to (6). However, steps (1), (2), (4), (5), (3), and (6) are performed. The setting may be made by.

In the above-described example, after specifying the weft insertion sequence for setting the control value read from the storage device and selecting the selection number corresponding to the control value read from the storage device, the setting command signal is generated and stored. The control value is read from the apparatus, and the control value is set in the weft insertion control unit 44 subsequent thereto. However, instead of this, for example, as in steps (01) to (05) below, reading from the storage device and setting to the weft insertion control unit 44 may be performed separately.
(01) The operator selects a selection number corresponding to the control value read from the storage device.
(02) With the generation of the read command signal based on the selection, the setting display device 46 reads the control value corresponding to the selection number selected from the storage device. (In this case, a dedicated display key (button) is provided.)
(03) The control value read in (02) is temporarily stored in the memory 49 such as the setting display device 46.
(04) The operator designates a weft insertion sequence (selection number) for setting the control value read from the storage device.
(05) With the generation of the setting command signal based on the designation, the setting display device 46 uses the control value stored in the memory at (03) as the control value of the selection number designated at (04). Set to.

  In this embodiment, the memory card 52 is used as a storage device, but the present invention is not limited to this example. For example, this multi-color weft insertion loom is connected to the host computer so as to be capable of two-way communication. The storage device according to the present invention is a memory of the host computer, and the weft insertion conditions stored in this memory are selected. A desired control value may be read. Further, a memory incorporated in the loom control device 42 of the multi-color weft insertion loom is used so that weft insertion conditions can be stored and read out, and a desired control value for the weft insertion conditions is selected and read from the memory. It is also good.

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