At the same time, the read numerical values of the five items are set in the control device (40).

As long as the warp type (yarn type) and thickness (yarn thickness) is a warp gluing machine for spun yarns, short fibers are targeted, and examples include the following.
Warp type (yarn type)
・ C …… Cotton ・ P / C (65/35) …… Polyester (65%) and cotton (35%) blend ・ P / C (50/50) …… Polyester (50%) and cotton (50%) ) Blends ・ P / R …… Polyester and rayon blends ・ P …… Polyester ・ R …… Rayon ・ W …… Wool Thickness of warp (thickness of yarn)
Specify from 5 to 160, depending on the count (the higher the count, the thinner the thread)

  The stretch ratio of the warp is the ratio of the peripheral speeds of the two actively driven rollers and can be expressed as [(the peripheral speed of the downstream roller / the peripheral speed of the upstream roller) −1] × 100 [%]. This value is obtained empirically and experimentally in consideration of the elongation during running of the sheet-like warp and the shrinkage due to drying. It is more stable than tension control by detecting warp tension, and obtains almost optimum tension. For example, when the stretch rate is increased and the warp tension is increased between the gluing device and the drying device, the warp yarn elongation is lost and the quality is deteriorated. Between the drying device and the winding device, the stretch ratio is increased, the warp tension is increased, and the warp sheet is easily divided using the yarn separating rod after drying.

  The drying device temperature is the temperature of the drying cylinder in the spun warp gluing machine. The temperature of the drying cylinder is controlled to a set temperature value by repeatedly supplying and stopping the high-temperature steam by on / off control of the electromagnetic on-off valve. In the filament yarn sizer (gluing machine), there are a hot air drying device and a drying cylinder in which a heat exchanger using high-temperature steam or an electric heater is provided on the hot air circulation path. Therefore, both or at least one of them is set temperature. Controlled by value.

  In addition, the temperature of the paste liquid is controlled to the optimum setting temperature by repeatedly turning on and off the electromagnetic on-off valve and repeatedly supplying and stopping the high-temperature steam that is put into the paste liquid in the paste liquid tank, similar to the drying device temperature. Controlled by value.

  The squeeze pressure is a force that acts between the rollers when the driven pressure is pressed against the driving roller by the fluid pressure cylinder and the paste is infiltrated into the yarn and the excess paste is squeezed out. The force is related to the adhesion amount (water content) of the paste liquid. The driven roller is usually covered with a high-friction elastic material such as rubber. Depending on the type of yarn and the thickness of the yarn, the amount of glue applied will decrease even if the squeeze pressure is increased by a predetermined value or more. In some cases, it is not necessary to set the squeeze pressure high. By setting an appropriate squeeze pressure according to the type of warp yarn and the thickness of the yarn, an appropriate amount of glue is adhered, and harmful effects and wasteful power caused by making the squeeze pressure higher than necessary are eliminated. In the embodiment, the squeeze pressure is set only for the second squeeze roller, but the squeeze pressure of the first squeeze roller may be set.

  As described above, the numerical values of the five items stored for each warp specification can be read out, displayed, corrected, and input with other numerical values, and can be controlled without changing or changing according to the setting command. It is set in the apparatus (claim 3). The numerical values of the five items stored for each warp specification are read and displayed and set in the control device (claim 4).

  According to the method of claim 1, the reference values for the five operating conditions are displayed on the display (43), and the reference values for the five operating conditions can be corrected and changed as necessary. Since the numerical value is stored in the storage device (42) separately from the reference value for each warp specification including the type, thickness, and number of the warp (2), the reference value and past numerical values are accumulated. Utilization makes it easy to set operating conditions thereafter.

  According to the method of claim 2, in addition to the effect of claim 1, the numerical values of the five items after correction / change are set in the control device (40). Thus, the control of the warp gluing machine (1) according to the above setting can be easily executed.

  According to the method of claim 3, in addition to the effect of claim 2, the numerical values of five items once stored for each warp specification are displayed, and after the numerical values are corrected and changed as necessary, the control device Since it is set to (40), it is possible to set new numerical values of five items in the control device (40) while referring to the numerical values of the past five items.

  According to the method of claim 4, since the numerical values of the five items stored for each warp specification are read from the storage device (42) and displayed, the read numerical values of the five items are set as they are in the control device (40). The numerical values of the past five items can be used effectively for the next control.

  FIG. 1 shows a main part of a warp gluing machine 1 for spun yarn as an example. In FIG. 1, a large number of warp yarns 2 are fed out as a sheet from a yarn feeding beam 3, and are guided to a gluing device 5 through, for example, four guide rollers 4. The beam shaft 3a of the yarn feeding beam 3 is braked by a brake pad 6 and a tension cylinder 7 for the brake pad 6. As a result, each warp 2 is pulled out under a predetermined warp tension on the delivery side. The warp tension on the delivery side can be detected by a tension detector 8 such as a load cell at the position of the third guide roller 4.

  In the gluing device 5, the warp yarn 2 is immersed in the gluing liquid 11 in the gluing tank 10 by the immersion roller 9, between the first sizing roller 12 and the first squeeze roller 13, and between the second sizing roller 14 and the second squeeze. After passing between the rollers 15 and being glued, they are divided into two parts and enter the first drying device 18. Both the first sizing roller 12 and the second sizing roller 14 are driven to rotate by a sizing motor 16 and a single chain (not shown) wound around them. In this example, the squeeze pressure of the first squeeze roller 13 is initially set by a fluid cylinder (not shown) and cannot be changed. However, the squeeze pressure of the second squeeze roller 15 is set to a predetermined value. Later, the squeeze cylinder 17 can be adjusted.

  In the first drying device 18, the warped yarns 2 divided into two are in contact with the outer peripheral surfaces of the drying cylinder 20 and the drying cylinder 21, respectively, are dried by receiving heat, merged via the guide roller 22, and then (2) Final drying is performed in contact with the outer peripheral surfaces of the drying cylinders 23 and 24 of the drying device 19. In the first drying device 18, the drying cylinders 20 and 21 are both driven by the drying motor 25 and one chain (not shown) wound around them and are rotated at the same peripheral speed. In the second drying device 19, the drying cylinders 23 and 24 are both driven by the drying motor 25 and one chain (not shown) wound around them, and rotate at the same peripheral speed as that of the drying cylinders 20 and 21. doing.

  After the gluing step and the drying step, the warp 2 is guided to the winding device 30 through the guide roller 26 and the dividing rod 27, and between the take-up roller 28 and the press roller 29, between the tension roller 31 and the guide roller 46. After that, it is taken up by the take-up beam 32. The take-up roller 28 and the take-up beam 32 are driven by a take-up motor 33 and a take-up motor 34, respectively. The rotational speed of the take-up roller 28 is substantially constant, but the rotational speed of the take-up beam 34 decreases as the winding diameter increases.

  The take-up beam 32 is removed from the take-up device 30 after the completion of the take-up, and is fed into the loom as a loom beam for supplying the warp yarn 2 on the loom. In the winding process, the warp tension on the winding side of the warp 2, that is, the winding tension of the warp 2 can be detected by a tension detector 35 such as a load cell at the position of the tension roller 31.

  Next, FIG. 2 shows the control device 40 of the warp gluing machine 1. The control device 40 controls the stretch rate, the paste temperature, the drying device temperature, the squeeze pressure and the warp tension, and the operation conditions such as a reference value of the operation condition from the operation condition setting device 41 or a numerical value corrected / changed from the reference value. Value data is received, and on / off control of the high-pressure steam 45 is performed by the electromagnetic on-off valves 36, 37, 38 based on the data of the operating condition value, and the sizing motor 16, drying motor 25, take-up motor 33, take-up motor are controlled. The number of rotations (rotational speed) 34 is controlled, and the adjustment control of the pressure fluid 44 in the tension cylinder 7 and squeeze cylinder 17 is further performed.

  The storage device 42 is provided with a product number storage unit and a reference value / arithmetic expression storage unit. The product number storage unit stores the product number for each warp specification including the type (yarn type), yarn count, and number of warps 2, and stores the product number and the operating condition value for each item of the product number. The arithmetic expression storage unit stores a reference value of the operating condition based on the yarn type and the count, and an arithmetic expression of the reference warp tension calculated from the yarn type, the count and the number of yarns. Corresponding data can be read.

  The operator inputs the warp specification consisting of the yarn type, yarn count and number, or if the part number of the warp specification or the part number of the warp specification similar to the warp specification can be found from the part number / warp specification comparison table, etc. Input to the device 39. When the operating condition setting device 41 receives the data of the yarn type, the count, the number, or the product number from the input device 39, the operating condition setting device 41 reads the reference value and the calculation expression of the reference warp tension from the reference value / calculation expression storage unit, The operating condition value corresponding to the product number is obtained from the product number storage unit or obtained, and the operating condition value is displayed on the display 43.

  Next, the operator operates the input device 39 to determine the operating condition value as it is, or after correcting / changing it as necessary. Further, the operator operates the input device 39 as necessary, performs product number registration by a storage command from the input device 39, and stores the product number to be registered in the product number storage unit and the operation condition value for each item of the product number. . The operating condition setting device 41 sends and sets the determined operating condition value to the control device 40 based on a setting command from the input device 39 by the operator's operation, and the determined operating condition value is displayed on the display 43. indicate.

  The control device 40 compares the warp tension (feed tension) on the delivery side detected by the tension detector 8 on the delivery side of the warp 2 with the target warp tension on the delivery side, and based on the deviation between them, The supply of the pressure fluid 44 is controlled. By this control, the tension cylinder 7 adjusts the friction force between the beam shaft 3a of the yarn feeding beam 3 and the brake pad 6 to thereby adjust the warp tension (feed tension) on the delivery side of the warp 2 to the target warp tension. Move closer to

  Further, the control device 40 compares the warp tension (winding tension) detected by the tension detector 35 on the winding side of the warp 2 with the target warp tension on the winding side, and based on the deviation between the two, The number of rotations (rotation speed) of the take-up motor 34 is controlled, whereby the warp tension (winding tension) on the winding side of the warp 2 is brought close to the target warp tension. Since the take-up motor 33 is rotated at a constant rotational speed (rotational speed), the control device 40 performs only on / off control accompanying the start or stop of the operation.

  The sizing motor 16 and the drying motor 25 basically cause the sheet-like warp 2 to travel at a predetermined speed in the gluing process and the drying process, and the rotation speed (rotational speed) of the sizing motor 16 is determined by the gluing device 5. This relates to the stretch ratio between the (second sizing roller 14 and second squeeze roller 15) and the second drying device 19 (drying cylinder 24). The rotational speed (rotational speed) of the drying motor 25 is determined by the stretch ratio between the gluing device 5 (second sizing roller 14 and second squeeze roller 15) and the first drying device 18 (drying cylinder 20), and the first. This is also related to the stretch ratio between the drying device 18 (drying cylinder 20) and the winding device 30 (take-up roller 28 / press roller 29). For this reason, the control device 40 receives the data of the operation condition value from the operation condition setting device 41, and based on each target stretch rate in the operation condition value, the rotation speed (rotation speed) of the sizing motor 16 and the drying motor 25. And adjust each stretch rate.

  The paste temperature (paste solution temperature) is controlled by repeatedly supplying and stopping the supply of the high-temperature steam 45 by the on / off control of the electromagnetic on-off valve 36. Further, the drying device temperature of the first drying device 18 (drying cylinders 20 and 21) and the drying device temperature of the second drying device 19 (drying cylinders 23 and 24) are high-temperature steam by ON / OFF control of the electromagnetic on-off valves 37 and 38, respectively. It is controlled by repeating 45 supply / supply stop. For this temperature control, the control device 40 detects the temperature of the paste (the paste temperature), the temperature of the drying cylinders 20 and 21, and the temperatures of the drying cylinders 23 and 24 using the temperature sensors 47, 48, and 49, and the detected temperatures. And on / off control of the electromagnetic on-off valves 36, 37, and 38 based on deviations from the target temperatures in the operating condition values from the operating condition setting device 41.

  In the warp gluing machine 1 described above, the storage device 42 has at least four reference values of stretch rate, paste temperature, drying device temperature, and squeeze pressure, and a calculation formula for the warp tension, and the type and thickness of the warp 2 It is stored accordingly.

  As described above, when operating the warp gluing machine 1, the operator inputs the type and thickness of the warp 2 and the number of warps 2 constituting one sheet via the input device 39, and the operating condition setting device A setting command is given to 41. At this time, the operating condition setting device 41 reads out the reference values in the above four items corresponding to the type and thickness of the warp 2 from the storage device 42, and uses the corresponding arithmetic expression and the number of the warp 2 that has been input, A reference value of (warp feed tension / warp take-up tension) is calculated, and the reference values of these five operating conditions are displayed on the display 43.

  The reference values of these five operating conditions can be corrected and input, or can be changed by inputting another numerical value. Therefore, the operator looks at the display screen of the display unit 43 and confirms the reference values of the five operating conditions, and partially corrects or changes the reference values as necessary. Later, a storage command is given to the operating condition setting device 41 by operating the input device 39. At this time, the operating condition setting device 41 registers the product number for each warp specification including the type, thickness, and number of warps 2 and stores them in the storage device 42 separately from the reference value of the operating conditions.

  Thereafter, when the operator operates the warp gluing machine 1, the product number is designated, and the numerical values of the five items corresponding to the warp specifications are read from the storage device 42 and displayed on the display 43, and the read five items are displayed. The numerical value is corrected / changed as necessary, and a setting command is given to the operating condition setting device 41 by operating the input device 39. At this time, the operating condition setting device 41 sets numerical values of at least five operating conditions in the control device 40 as final target values for the respective controls. With this setting, the control device 40 executes the above-described control using the five items, that is, the stretch rate, the paste temperature, the drying device temperature, the squeeze pressure, and the values of the warp tension on the delivery side and the take-up side as the target values for the respective controls. It will be ready.

  As described above, the numerical value of the operating condition for each warp specification, that is, for each product number, is stored in the storage device 42 one after another based on the reference value of the initial operating condition, and is accumulated as past usable data. After that, it can be used as it is, or while being modified or changed. Accordingly, when the operator operates the warp gluing machine 1 from the next time onwards, the warp specification, that is, the product number, of the warp 2 to be glued is designated, and the numerical values of the five items corresponding to each product number are read from the storage device 42 and displayed. The display unit 43 displays the five items of numerical values directly in the control device 40, or corrects / changes them as necessary, and stores the corrected / changed numerical values of the five items in the storage device 42. At the same time, it is stored in the control device 40.

  3, 4 and 5 show examples of the display screen 1, the display screen 2 and the display screen 3 of the display device 43, respectively. In these examples, the display device 43 is a touch panel system, and some functions of the input device 39 are provided on the display screen.

  First, on the display screen 1 of FIG. 3, by touching the “input” key on the display screen, function keys in addition to the numeric keypad appear on the display screen as the input device 39, and numbers and the like can be input. Use the “↑” and “↓” function keys to move the input position in the thread specification table on the display screen, and use the numeric keypad to enter the thread number and thread number (the thread number table is displayed. Is automatically displayed.) Enter the number of warps (number of yarns). When all the items in the thread specification table have been input, touching the “END” key of the function key and then touching the “EXECUTE” key on the display screen switches to the display screen 2 in FIG.

  Next, in the display screen 2 of FIG. 4, each reference value is displayed in a table of squeeze pressure, a table of tension (warp tension), a table of stretch rate, and a table of temperature (glue temperature / drying device temperature). Yes. All the reference values can be corrected and changed by the input device 29 on the screen. When the reference value is to be changed, by touching the “input” key, a function key appears in addition to the numeric keypad and can be input. . Use the “↑” and “↓” keys to move the input position of each table, and use the numeric keypad to enter a numerical value at each input position. When all the reference values are as desired, touch the “End” key. Touch the “Part number registration” key and enter the part number in the part number field using the numeric keypad. When the “end” key is touched, the product number for each warp specification is stored, and the numerical value of the last displayed content is used as the operating condition value to store each reference value in the storage device 42 and the storage area of the arithmetic expression, that is, the reference value / calculation It is stored in a storage area different from the expression storage unit, that is, the product number storage unit.

  Finally, when the key of “Part number table screen” is touched, the screen is switched to the screen 3 in FIG. On the display screen 2, when the value of the display content is set as it is as the actual operation setting condition value, the “setting” key is touched. When changing a part of the value of the display content, touching “Input” causes a numeric keypad to appear, and a number to be changed can be input. When all the displayed values are the desired values, the “end” key is touched, and then the “setting” key is touched.

  In the display screen 3 of FIG. 5, only the stored product number and its yarn (yarn type and yarn count) are displayed in the product number table. No. of the part number you want to see Touching the number in the field and touching the “Details” key switches to the display screen 2.

  In addition to the above-exemplified items, the moisture content may also be stored, displayed, and set. The moisture content is a value indicating the degree of drying of the warp 2 after gluing and drying, and is represented by the formula: moisture content [%] = (100 × moisture weight) / (warp weight + glue weight + moisture weight). At the time of measuring the moisture content, a moisture content measuring device is provided in the vicinity of the winding device 30, and the moisture content of the warp 2 is measured at that position. Then, the control device 40 controls the traveling speed of the warp 2 based on the deviation between the measured moisture content and the operating condition value (target moisture content), or sets the drying device temperature or the squeeze pressure as the operating condition. Control is performed within a predetermined amount range from the value.

  Furthermore, the operating conditions for low-speed operation can also be stored, displayed, and set. The low speed operation is an operation when the yarn breakage processing or the like is performed without stopping the warp gluing machine 1 at an operation speed of about 10% of the normal operation. For example, two operating condition values for the stretch rate and the squeeze pressure are provided for normal operation and low-speed operation. In actual control, the squeeze pressure is lowered because the paste 11 is well squeezed out at low speed, and the stretch rate is lowered because it is often dried and contracted at low speed.

  In this embodiment, the product number is registered for each warp specification including the yarn type, yarn count, and number of warps 2, and the storage device 42 stores the product number and the operating condition value for each item of the product number. The operation condition value for each warp specification stored in the storage device 42 can be easily read out, but the product number does not necessarily have to be registered for each warp specification. Only the operating condition value may be stored.

  Further, when the operation condition value is read from the storage device 42 by the product number and set in the control device 40, the operation condition value is corrected and changed as necessary and set in the control device 40, but is read from the storage device 42. At the same time, the operating condition value may be set in the control device 40. By doing so, the operation of the input device 39 by the operator can be reduced.

  Furthermore, in the display screen 2 of FIG. 4 of the present embodiment, the display part for the reference value of the operating condition and the reference value correction / change part that is the input part of the operating condition value are provided as the same, The value is rewritten to the desired value as the operating condition value. However, when the operating condition reference value display section and the operating condition value input section correction / change section are provided on separate screens or on the same screen, they must be installed at different positions. In addition, it is possible to input a numerical value to the correction / change unit while referring to the reference value, and it is possible to eliminate an input error of the operating condition value.

  The method of the present invention is used for the control of the warp sizing machine 1, but the operating condition data of the warp sizing machine 1 is fed back to the previous process of the warp sizing machine 1 and is used for the control in the subsequent weaving process. Can also be used.

It is a side view of a warp gluing machine. It is a block diagram of the control system of the warp gluing machine 1. 4 is an explanatory diagram of a display screen 1. FIG. It is explanatory drawing of the display screen. It is explanatory drawing of the display screen.
