DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wetting apparatus for immersing a warp in a sizing solution in which sizing is dissolved in water to paste the warp, and wetting the warp with water before sizing the warp. The present invention relates to a sizing solution concentration control method and apparatus in a sizing machine provided with a sizing solution concentration adjusting means for adjusting the concentration.

[0002]

2. Description of the Related Art A sizing process in which a warp is wetted with water before sizing is performed on a warp increases the sizing effect and reduces the amount of sizing material. Generally, 8 stored in a water tank
It is known that after passing a warp through hot water at 0 ° C. to 90 ° C., it is effective to glue the warp after dewatering the warp wetted with water to a predetermined moisture content.

[0003] As a wetting device for wetting the warp, a water storage tank storing water for wetting the warp, an immersion roller immersed in the water in the water storage tank, and a water surface in the water storage tank are provided. Above this, a configuration is generally provided which includes a squeezing roller rotatably pressed against the peripheral surface of the immersion roller via a warp wound around the peripheral surface of the immersion roller.

[0004] The wet warp is passed through a sizing liquid in a sizing tank that stores a sizing liquid for sizing the warp. The warp thread that has passed through the size liquid in the sizing tank releases water into the sizing tank, and the size liquid in the sizing tank is diluted by the water released from the warp threads. The warp passed through the size liquid in the size tank is
In order to pick up the sizing liquid from the sizing tank, it is necessary to supply the sizing liquid to the sizing tank. In order to replenish the sizing liquid in the sizing tank and to control the sizing liquid concentration in the sizing tank to the target concentration, a sizing liquid having a higher concentration than the target concentration is supplied to the sizing tank.

However, the concentration of the replenishing size liquid is determined by the moisture pick-up rate of the warp (the value obtained by dividing the weight of water picked up from the water tank by the unit weight of the warp by the unit weight), or the moisture rate of the warp before sizing. It does not correspond exactly to etc. For this reason, if the size liquid of a certain concentration is continuously supplied, the density of the size liquid in the size tank gradually deviates from the target concentration, and proper sizing is impaired.

In order to always control the size concentration in the size tank to the target concentration, the size concentration in the size tank is measured every time the size solution is replenished, and the concentration of the size solution to be supplied is measured. The electric feedback control of adjusting according to is performed. Actually, a high-density sizing liquid and a low-density sizing liquid are prepared, or a high-concentration sizing liquid and water are prepared. The mixing ratio or the mixing ratio of the high concentration size liquid and water is adjusted to adjust the concentration of the size liquid to be replenished.

[0007]

In the state where the size concentration in the size tank is at the target concentration, control conditions relating to the size concentration adjustment (for example, mixing of a high-size size solution and a low-size size solution). Ratio or mixture ratio of high concentration paste liquid and water)
Is in a stable state with very little fluctuation. However, if the operating conditions of the gluing machine, for example, the operating speed that directly affects the moving speed of the warp (that is, the motor rotation speed) is changed, the control condition relating to the size liquid density adjustment is out of the stable state. That is, after changing the operating condition of the gluing machine, the control condition regarding the size liquid density adjustment starts from the unstable state which is out of the stable state. As described above, when the control condition starts from an unstable state, it takes time to obtain the optimum control condition. That is, it takes time before proper gluing is performed after the start of operation.

It is an object of the present invention to shorten the time required for the control condition regarding the size liquid concentration adjustment in a sizer equipped with a wetting device to reach a stable state.

Since the sizing liquid is circulating between the sizing tank 17 and the sizing liquid tank 24, the concentration of the sizing liquid in the sizing tank 17 and the concentration of the sizing liquid in the sizing liquid tank 24 can be regarded as the same. Then, main controller C1 controls the adjustment of the water squeezing amount by water pickup ratio adjusting means 55 so that the estimated concentration of the size liquid approaches target concentration Do.

The estimation of the concentration D (%) of the size liquid is based on the following equation (1). D = (DS / PS) × (A-PW) × [1- {M / (100 × L)} × (A-PW-PS)] (1) DS is supplied from the size liquid supply source 25. The PS represents the concentration (%) of the size liquid supplied to the size liquid tank 24, and PS represents the size liquid pickup ratio (%) of the size liquid picked up by the warp T passing through the size liquid in the size tank 17.

Assuming that the moisture content released into the sizing tank 17 is PWA (%) and the moisture content retained by the warp T without being released into the sizing tank 17 is PWB (%), 2) holds. However, the moisture content that the warp T normally has before wetting is excluded from the moisture content PW.

PW = PWA + PWB (2) Immediately after the size liquid is supplied from the size liquid supply source 25 to the size liquid tank 24, the warp size pasted becomes M, that is, from the size liquid supply source 25. Assuming that the sizing liquid concentration in the sizing tank 17 immediately before the sizing liquid is newly supplied to the sizing liquid tank 24 is DD, the sizing liquid concentration DD
Is represented by the following equation (3) regarding the amount of pure paste in the paste liquid.

(D / 100) × L = (DD / 100) × {L + (PWA / 100) × M} (3) The left side in the equation (3) is the size of the glue tank 17 and the size liquid tank 24. Represents the amount of pure paste contained in the paste liquid when the total amount of paste liquid is the management capacity L. The right side in the equation (3) represents the amount of pure paste contained in the paste liquid when the amount of water (PWA / 100) × M released from the wet warp T into the paste tank 17 is added.

Equation (3) is rewritten into the following equation (4). DD = 100 × D × L / (100 × L + PWA × M) (4) At this time, the pure paste amount of the paste liquid to be supplied to the paste liquid tank 24 is represented by SS
(Kg), the pure size SS is represented by the following formula (5) which is the product of the total size (PS / 100) × M of the size liquid picked up by the warp T and this concentration DD.

SS = (DD / 100) × (PS / 100) × M = {100 × L × D / (100 × L + PWA × M)} × PS × M = (1/100) × L × D × PS × M / (100 × L + PWA × M) (5) Assuming that the volume of the size liquid to be replenished is LL (kg), the replenishment size liquid LL is the amount of size liquid picked up by the warp T from the size tank 17. Is the value obtained by subtracting the moisture released from the warp T into the sizing tank 17 and is represented by the following equation (6).

LL = PS / 100) × M− (PWA / 100) × M = (M / 100) × (PS−PWA) (6) The concentration DS (%) of the size liquid to be replenished is Net glue amount SS to be replenished
Is divided by the replenishment size liquid volume LL, and is expressed by the following equation (7).

DS = 100 × SS / LL = PS × D {[(PS−PWA) × {1 + PWA × M / (100 × L)}] (7) When the warp T is pasted without being wetted in advance Glue tank 1
7 are the size liquid pickup rate PS from the sizing tank 17 when wet and sizing in advance, and the moisture rate PW retained without releasing to the sizing tank 17.
This is the sum with B and is expressed by the following equation (8).

A = PWB + PS (8) By substituting equation (2) into equation (8), the following equation (9) is obtained. PWA = PW-A + PS (9) By substituting equation (8) into equation (7), the following equation (10) is obtained.

DS = PS × D {[(A−PW) × [1− {M / (100 × L)} × (A−PW−PS)] (10) The size liquid density D Equation (1) is obtained from Equation (10).

D = (DS / PS) × (A-PW) × [1- {M / (100 × L)} × (A-PW-PS)] (1) Glue in the formula (1) The liquid pick-up rate A is a constant that can be expressed by actual data when the warp T is pasted without being wetted beforehand, and the size liquid management capacity L is also a constant of the equipment condition. Also, the replenishing size liquid concentration DS is a constant if measured in advance as long as the resized size liquid is the same, and the warp amount M can be easily obtained as the output during the sizing. Therefore, by measuring the current moisture pickup rate (hereinafter, referred to as PWx) and the current size liquid pickup rate (hereinafter, referred to as PSx), the size density D can be estimated using the equation (1). .

Assuming that the amount of size liquid newly replenished after the last size liquid replenishment is MS (kg), the current size liquid pickup rate PSx is obtained by dividing the size liquid amount MS by the amount of warp M glued during this time. And is represented by the following equation (11).

PSx = (MS / M) × 100 (11) The water newly replenished after the last replenishment of the size liquid is expressed by MW (k
g), the current moisture pickup rate PWx is a value obtained by dividing the moisture MW by the warp amount M, and is expressed by the following equation (12).

PWx = (MW / M) × 100 (12) The water pickup rate PW is expressed by the following equation (13) derived from the equation (1) for estimating the size D of the size liquid.

PW = A− (M / 2) × [(100 × L + M × PS) − {(100 × L + M × PS) ² −4 × M × 100 × L × (D / DS) × PS} ^{1 / 2} ] (13) When the target concentration Do is adopted as the size liquid concentration D in the expression (13) and the size liquid pickup ratio PS is measured, the water pickup ratio PW represented by the expression (13) becomes The target moisture pickup rate PWo is expressed by the following equation (14).

PWo = A− (M / 2) × [(100 × L + M × PS) − {(100 × L + M × PS) ² −4 × M × 100 × L × (Do / DS) × PS} ^{1 / 2} ] (14) Accordingly, the current moisture pickup rate PWx represented by the equation (12) is changed to the target moisture pickup rate represented by the equation (14).
When deviating from PWo, the current moisture pickup rate
If PWx is controlled so as to approach the target moisture pickup rate PWo, the size density D estimated by the equation (1) becomes the target density.
Get closer to Do.

When the warp amount M is sufficiently smaller than the control capacity L, that is, when the size liquid replenishment time interval is close to the continuous replenishment, the equation (1) indicates that the control capacity L and the warp amount M Regardless, it can be approximated by the following equation (15).

D = (DS / PS) × (A−PW) (15) The water pickup rate PW can be approximated by the following equation (16) derived from the equation (15).

PW = A− (D / DS) × PS (16) The replenishment size DS is calculated by the following equation (1) derived from the equation (15).
7) can be approximated. DS = D × PS / (A−PW) (17) Expressions (11) and (13) are input to the main control device C1 by the input device 32 before the operation of the gluing machine. or,
The replenishing size liquid concentration DS, the size liquid pickup rate A, the target concentration Do, and the management capacity L are also input to the main controller C1 by the input device 32 before the operation of the sizer. Supply size liquid concentration DS
Is approximated using equation (17). In equation (17), the sizing solution concentration D is the size solution concentration actually measured before operation, the sizing solution pickup rate A is a constant as data based on the actual results, As the size pick-up rate PS and the moisture pick-up rate PW, values that temporarily assume values during operation are used.

The replenishment size DS which has been set higher in advance is obtained by an approximate calculation, and there are other condition changes during the operation of the sizer. Therefore, if the replenishing of the sizing solution is continued with the operation of the sizing machine, the actual sizing solution concentration D deviates from the sizing solution concentration before operation, that is, the target concentration Do, and proper sizing is impaired. Therefore, the size liquid density D during the operation of the sizer is
You need to know. Equation (1) indicates that the current size liquid concentration D can be estimated by measuring the current water pickup rate PWx and the current size liquid pickup rate PSx. Equation (13) derived from Equation (1) is a mere modification of Equation (1) and is the same as Equation (1). Therefore, equation (13) indicates that the current size liquid concentration D can be estimated by measuring the current water pickup rate PWx and the current size liquid pickup rate PSx. Equation (13)
Represents the target moisture pickup rate PWo, where the size D is the target concentration Do. Therefore, the current moisture pickup rate
By performing control to make PWx close to the target moisture pickup rate PWo, the current size liquid concentration D can be made close to the target concentration Do.

Now, when the operation of the gluing machine is started in a state where the auxiliary control device C2 is in the first execution standby mode, the main control device C1 supplies the size liquid from the size liquid supply source 25 to the size liquid tank 24. The following calculation is performed every time. First, the main controller C1
Calculates the warp amount M based on the measurement information obtained from the rotation number integrator 31. Then, main controller C1 calculates expression (11) based on the calculated warp amount M and the measurement information (ie, the replenishing size liquid amount MS) obtained from level sensor 27, and calculates the current size liquid pickup rate PSx Is calculated. The level sensor 27 serves as a size liquid pick-up rate measuring means for measuring the size liquid pick-up rate of the size liquid picked up by the warp passing through the size liquid. Further, main controller C1 includes measurement information (that is, replenishing size liquid amount MS) obtained from level sensor 27, the calculated warp yarn amount M, the calculated size liquid pickup ratio PSx, and the previously input size liquid pickup. Formula (13) is calculated based on the rate A, the pre-input management capacity L, the pre-input target density Do, and the pre-input replenishment liquid density DS to calculate the target moisture pickup rate PWo. . That is, main controller C1
Calculates the target moisture pickup rate PWo by updating the size liquid pickup rate PS and the warp amount M in equation (13) every time the size liquid is supplied from the size liquid supply source 25 to the size liquid tank 24.

After calculating the target water pickup rate PWo, the main controller C1 compares the measurement information obtained from the flow meter 44, that is, the current water pickup rate PWx, with the calculated target water pickup rate PWo. Perform The flow meter 44 serves as a moisture content measuring means for measuring the moisture content of the wet warp yarn before immersion in the size liquid. If the current size liquid concentration D is lower than the target concentration Do, the current water pickup rate PWx is higher than the target water pickup rate PWo. Conversely, when the current size liquid concentration D is higher than the target concentration Do, the current water pickup rate PWx is lower than the target water pickup rate PWo. Current moisture pickup rate PWx is the target moisture pickup rate PWo
When the difference | PWx−PWo | is beyond the allowable range, main controller C1 performs control to decrease the degree of pressure reduction in pressure controller 43 and increase the pressure of the compressed air. By this control, the pressing force of the squeezing roller 16 against the immersion roller 15 is increased, and the current water pickup rate PWx is reduced to approach the target water pickup rate PWo. If the current moisture pickup rate PWx is lower than the target moisture pickup rate PWo and the difference | PWx−PWo | is outside the allowable range, the main controller C1 sets the pressure controller 4
In step 3, control is performed to increase the degree of pressure reduction to reduce the pressure of the compressed air. By this control, the pressing force of the squeezing roller 16 against the immersion roller 15 is weakened, and the current moisture pickup rate PWx increases to increase the target moisture pickup rate PW.
approach o.

Making the current water pickup rate PWx close to the target water pickup rate PWo means that the current size liquid concentration D approaches the target concentration Do. When the difference | PWx−PWo | between the current moisture pickup rate PWx and the target moisture pickup rate PWo is within the allowable range, main controller C1 does not perform control to change the degree of pressure reduction in pressure controller 43. .

The main controller C1 for controlling the current size liquid concentration D to approach the target concentration Do has two modes, when the gluing machine starts operating, when the auxiliary control device C2 is in the first execution standby mode, Different control is performed when the apparatus is in the standby mode. When the auxiliary control device C2 is in the first execution standby mode, when a registered product number is specified by the input device 49 and operating conditions are input, the auxiliary control device C2 registers the specified registered product number (hereinafter, referred to as N). The operating condition is stored in the operating condition storage device 46 in association with the designated registered product number N while being stored in the product number storing device 45.
Then, the auxiliary control device C2 instructs the main control device C1 to start the size liquid concentration control, and starts the operation of the gluing machine. Main controller C1 performs the above-described concentration control based on a command for starting the size liquid concentration control.

The state where the difference | PWx−PWo | between the current moisture pickup rate PWx and the target moisture pickup rate PWo is within the allowable range will eventually become steady. After a lapse of time expected to reliably bring this steady state, the auxiliary control device C2 converts the pressure information of the compressed air obtained by the pressure detector 53 into the control condition in association with the registered product number N. It is stored in the storage device 47. That is, the auxiliary control device C2 determines whether or not the expected time has elapsed,
A function is provided for determining whether or not the estimated size concentration has reached the target concentration.

When the auxiliary control device C2 is in the re-execution standby mode, the registered product number stored in the registered product number storage device 45 is displayed on the display device 50. When pasting the registered product number N, it is assumed that the registered product number N to be pasted is displayed on the display device 50. In this case, the input device 49
When the registered part number N is designated by the central processing unit 48, the central processing unit 48 reads out the operating conditions and control conditions (that is, the pressure information of the compressed air) stored in relation to the registered part number N. Then, the auxiliary control device C2 instructs the main control device C1 to start the size liquid concentration control based on the control condition (that is, the pressure information) stored in relation to the registered product number N. Further, the auxiliary control device C2 starts the operation of the gluing machine under the operating conditions stored in relation to the registered product number N. Main controller C1
Performs the density control under the control conditions stored in relation to the registered product number N based on the size liquid density control start command.
That is, the auxiliary control device C2 controls the density via the main control device C1 under the control conditions stored in relation to the registered product number N.

When the difference | PWx−PWo | between the current moisture pickup rate PWx and the target moisture pickup rate PWo falls within the allowable range, main controller C1 determines that the estimated size concentration has reached the target concentration. to decide. Based on this determination, the main control device C1 performs density control by normal feedback control instead of the density control by the auxiliary control device C2.

In the first embodiment, the following effects can be obtained. (1-1) When the pasting of the registered part number N stored in the registered part number storage device 45 is started, if the registered part number N is designated, the auxiliary control device C2 stores the information related to the registered part number N. The operation of the gluing machine is controlled by operating conditions. Further, the auxiliary control device C2 starts the control of the sizing liquid concentration adjustment by the water pickup ratio adjusting means 55, which is the sizing liquid concentration adjusting means, under the control conditions stored in relation to the registered product number N. Adoption of past operating conditions and control conditions obtained when the size concentration estimated in the registered product number N is the target concentration reduces the time required for the control conditions relating to size concentration adjustment to reach a stable state. Ideal for

(1-2) Main Control Unit C1 as Main Control Means
Has a function of determining whether or not the estimated size concentration has reached the target concentration. It is assumed that the main control device C1 determines that the estimated size concentration has reached the target concentration while the auxiliary control device C2, which is the auxiliary control means, controls the size concentration adjustment. Then, the control of the size liquid concentration adjustment by the auxiliary control device C2 is switched to the feedback control of the size liquid concentration adjustment by the main control device C1. After the estimated size concentration reaches the target concentration, the feedback control of the size control by the main control device C1 is more effective than the control of the size control by the auxiliary control device C2 with the control conditions fixed. It becomes proper control.

(1-3) A certain registered product number Z is glued to the electric motor Mo at a rotation speed that provides a yarn speed of 100 m / min, which is an operating condition, and the electric motor Mo is driven at a yarn speed of 50 m for the same new registered product number Z. / Min. Then, the control of the size concentration adjustment by the moisture pickup rate adjusting means 55 is affected by the change in the rotation speed, and the pressure of the compressed air in the moisture pickup rate adjustment means 55 is reduced when the control of the size density adjustment is stabilized again. Will change. For this reason, the registered part number N is different from the registered part number N only under the operating conditions.
When the same kind of warp is pasted, it is necessary to assign a registered product number different from the registered product number N. If a different registered product number is assigned to each of the gluing targets having different operating conditions, it is easy to re-execute the operating conditions even if the operating conditions are changed.
