Description

  The present invention relates to a liquid flow type fabric processing apparatus for performing various processes on a fabric.

  2. Description of the Related Art Conventionally, there has been known a liquid-flow type cloth processing apparatus for performing various processing such as dyeing and washing on cloth (see Patent Document 1). As shown in FIG. 2, the liquid-flow type cloth processing apparatus has an inlet section 102 and an outlet section 103, and a processing tank 101 in which the processing liquid W stays, an inlet section 102 and an outlet section 103 of the processing tank 101. And a transfer pipe 110 that forms a circulation path through which the fabric C can circulate, and a liquid supply system 120 that supplies the processing liquid W from the processing tank 101 to the outlet 103. Here, the processing liquid W is a liquid for processing a fabric such as a dyeing liquid and a cleaning liquid, and is a liquid obtained by diluting components according to the processing content of the cloth with water or the like.

  Specifically, the processing tank 101 is a tank that is long in the horizontal direction, and has an inlet 102 at one end in the longitudinal direction and an outlet 103 at the other end. The outlet 103 includes a nozzle 104 for discharging a processing liquid (a dyeing liquid or a cleaning liquid) W, and a reel 105 for transferring and guiding the cloth C.

The liquid supply system 120 has a plurality of discharge units 121 connected to a lower part of the processing tank 101 to discharge the processing liquid W from the processing tank 101, and the processing discharged from the processing tank 101 through the plurality of discharge units 121. The liquid W is supplied to the nozzle 104 of the outlet 103. Each discharge unit 121 is provided with a valve or the like (not shown) capable of adjusting the discharge amount of the processing liquid W.

  Further, the liquid supply system 120 includes a pump 125 that sends out the processing liquid W in the processing tank 101 toward the nozzle 104, and a heat exchanger 126 that can heat or cool the processing liquid W. After heat exchange (heating or cooling), it can be supplied to the nozzle 104.

  In the liquid-flow type cloth processing apparatus 100, when processing the cloth C, the long cloth C is inserted into the processing tank 101 and the transfer pipe 110, and both ends thereof are connected. Thereby, the cloth C becomes a loop shape that can circulate through the circulation path formed by the processing tank 101 and the transfer pipe 110. At this time, the cloth C is hung on the reel 105 at the outlet 103 of the processing tank 101.

  In this state, at the outlet 103 of the processing tank 101 of the liquid flow type cloth processing apparatus 100, the nozzle 104 pulls up the cloth C in the processing liquid W while the nozzle 104 applies the processing liquid W to the cloth C hanging down from the reel 105. By discharging, the cloth C in the processing tank 101 is sequentially sent to the transfer pipe 110. In the transfer pipe 110 of the liquid flow type cloth processing apparatus 100, the fabric C in the transfer pipe 110 is sequentially processed by the flow of the processing liquid W flowing through the transfer pipe 110 (the processing liquid W from the nozzle 104). It is sent to the inlet 102 of the tank 101. Further, in the processing tank 101, a predetermined liquid level (liquid level position) is maintained, so that the fabric C floats in the processing liquid W in the processing tank 101, and is downstream of the processing tank 101 (on the reel 105 side). ). Thereby, in the liquid-flow type cloth processing apparatus 100, the loop-shaped cloth C is circulated in the processing tank 101 and the transfer pipe 110 (circulation path). In this circulation, the cloth C passes through the processing liquid W in the processing tank 101 while staying in the processing liquid 101, thereby performing the cloth processing such as dyeing and washing.

JP-A-2002-105842

  In the above-mentioned liquid-flow type cloth processing apparatus 100, at the time of starting operation, the operator checks the state of retention of the cloth C inside from the viewing window 106 provided on the outlet 103 side of the processing tank 101 while checking the valve of each discharge section 121. , The discharge amount of the processing liquid W from each discharge unit 121 is adjusted, whereby the cloth C staying in the processing tank 101 is biased toward the inlet 102 or the outlet 103 of the processing tank 101. That is, the cloth C is adjusted so as to stably circulate in the circulation path (in the processing tank 101 and the transfer pipe 110).

  However, the state of staying of the cloth C and the state of the processing liquid W in the entire processing tank 101 is checked through the viewing window 106, and adjustment of each valve for stably circulating the cloth C requires skill. . For this reason, when an inexperienced operator operates the liquid-flow type cloth processing apparatus 100, the cloth capacity to be processed is reduced, or the amount of the processing liquid W is increased, and stable operation is performed. It could not be done efficiently without trouble.

  Therefore, an object of the present invention is to provide a liquid flow type cloth processing apparatus capable of performing efficient cloth processing regardless of the skill of an operator.

  The inventors of the present invention have conducted intensive studies in order to solve the above-mentioned problems, and as a result, have found the following.

  Analysis of a large number of data (past performance data, newly collected data, etc.) on the processing liquid and the staying state (behavior) of the cloth in the processing tank revealed that the cloth was found to be running during the operation of the liquid-flow cloth processing apparatus. When circulating stably (stable running), the level of the processing solution staying in the processing tank is higher at the inlet side than at the outlet side of the processing tank (in other words, the cloth in the processing tank is (The rear side is higher than the front side in the traveling (moving) direction of the vehicle). The inclination angle of the liquid level when the cloth runs stably changes when the shape and size of the processing tank, the type of the cloth, and the processing content of the cloth change. Of the same type and the processing content of the cloth), the processing becomes almost the same each time.

  In addition, if the inclination (angle) of the liquid surface of the processing liquid changes during the operation of the liquid-flow type cloth processing apparatus, the running state of the cloth changes. Furthermore, if the amount and temperature of the processing liquid are changed during the operation of the liquid-flow type cloth processing apparatus, the processing liquid stays in the processing tank due to the change in the properties of the cloth and the processing liquid accompanying the change in the liquid amount and temperature. Of the liquid level changes, and the running state of the cloth changes. Even in this case, the stable running (stable circulation) of the fabric is maintained by adjusting the valve or the like of each discharge unit so that the inclination of the liquid level does not change.

  Therefore, based on these findings, the inventors paid attention to the inclination of the liquid surface of the processing liquid staying in the processing tank when performing the cloth processing, and created a liquid flow type cloth processing apparatus having the following configuration.

  The liquid flow type fabric processing apparatus of the present invention is provided with a first end portion, a second end portion opposite to the first end portion, and disposed between the first end portion and the second end portion for processing. A processing tank having a main body for retaining the liquid, a transfer pipe connecting the first end and the second end to form a circulation path through which the cloth can circulate, A liquid supply system for supplying to the first end or the transfer pipe; and a liquid level detection unit for detecting a liquid level of the processing liquid staying in the main body, wherein the liquid supply system is provided at a lower part of the main body. At least one pair of discharge units connected to positions spaced apart in the movement direction of the cloth and configured to discharge the processing liquid from the main body unit, and an adjustment unit that adjusts a discharge amount of the processing liquid by the pair of discharge units. Wherein the adjusting unit is configured to process the processing liquid in the main body based on the liquid level detected by the liquid level detecting unit. The level of the second end side is higher than the liquid level or the first end side, and so that the fabric becomes a reference surface of an inclination such that the cloth stably circulates in the circulation path, the pair of discharge units The discharge amount of the processing liquid discharged from at least one of the discharge units is adjusted.

  According to this configuration, during operation (during processing of the fabric), the processing liquid from at least one of the discharge units is adjusted by the adjusting unit such that the liquid level of the processing liquid staying in the processing tank (main body) becomes the reference surface. Is adjusted, the cloth runs stably (circulates stably). Thereby, regardless of the skill of the operator (that is, even if the operator does not have the skill, it is not necessary to operate with a small cloth volume to be processed and a large amount of the processing liquid), so that efficient cloth processing can be performed. It becomes possible.

  In this case, in the liquid-flow-type cloth processing apparatus, the adjustment unit may perform processing in the main body unit in a state where at least one of the property of the cloth, the property of the processing liquid, and the amount of the processing liquid in the processing tank is changed. It is preferable to adjust the discharge amount of the processing liquid discharged from the at least one discharge unit so that the liquid level of the liquid becomes the reference surface.

  When at least one of the property of the cloth, the property of the treatment liquid, and the amount of the treatment liquid in the main body is changing based on the temperature of the treatment liquid, the inclination of the liquid surface of the treatment liquid staying in the treatment tank changes. Therefore, at least in a state where the properties and the amount of the liquid are changing, the inclination of the liquid surface of the processing liquid is controlled so as to be the reference surface, so that the cloth can be easily run stably.

  In addition, the adjusting unit may be configured to perform the processing discharged from the at least one discharging unit such that a liquid level of the processing liquid in the main body part becomes the reference surface when the processing liquid is at least at a temperature at which the fabric softens. The discharge amount of the liquid may be adjusted.

  Since the softening (change in properties) of the cloth most affects the inclination of the liquid level of the processing liquid, the inclination of the liquid level is controlled so that the liquid level of the processing liquid becomes the reference plane at least in a state where the cloth is softened. This makes it easier for the fabric to run more stably.

  Further, in the liquid-flow type cloth processing apparatus, the liquid level detecting unit has a pair of liquid level gauges for detecting the liquid level of the processing liquid at positions spaced in the moving direction of the cloth in the main body. The adjustment unit may adjust the discharge amount of the processing liquid from at least one of the discharge units based on a difference between the liquid level positions detected by the liquid level meters.

  Thus, a simple configuration utilizing the fact that the inclination of a straight line including these two points with respect to the horizontal plane can be obtained from the difference between the horizontal distance and the height of the two points, that is, in the moving direction (running direction) of the cloth A simple configuration, such as providing a pair (two) of liquid level gauges so that two liquid level positions spaced apart can be detected, accurately detects the inclination of the processing liquid level in the processing tank. Can be.

  As described above, according to the present invention, it is possible to provide a liquid flow type cloth processing apparatus capable of performing efficient cloth processing regardless of the skill of the operator.

The liquid supply system 4 may be connected to supply the processing liquid W to the transfer pipe 3 (for example, an end of the transfer pipe 3 on the first end 21 side).

  The pair of discharge portions 41 and 42 are connected to positions below the main body portion 23 at intervals in the moving direction of the fabric C (the left-right direction in FIG. 1). Hereinafter, the discharge part 41 connected to one end of the main body 23 is referred to as a first discharge part, and the discharge part 42 connected to the other end of the main body 23 is referred to as a second discharge part.

The processing liquid W is discharged. By connecting the first discharge pipe 411 to the position where the processing liquid W that has passed through the second guide member 26 flows in this way, when the processing liquid W in the main body 23 flows into the first discharge pipe 411, the cloth C can be prevented from flowing into the first discharge pipe 411 together with the processing liquid W.

When flowing into the discharge pipe 421, the fabric C can be prevented from flowing into the second discharge pipe 421 together with the processing liquid W.

  The adjusting unit 43 adjusts the liquid level Ws of the processing liquid W in the processing tank 2 (the main body unit 23) based on the liquid level Ws of the processing liquid W in the processing tank 2 detected by the liquid level detecting unit 5. Alternatively, the processing liquid discharged from at least one of the pair of discharge units 41 and 42 such that the other end side (the second end 22 side) is higher than the one end side (the first end 21 side) as a reference surface. Adjust W emission. Here, the reference surface is a surface that the liquid surface Ws of the processing liquid W in the processing tank 2 aims at (targets) during the processing of the fabric C, and the liquid surface Ws of the processing liquid W is defined as the reference surface. If the surfaces are coincident or substantially coincident with each other, the surface is such that the fabric C stably circulates in the circulation path. This reference plane is a plane determined from past performance data, simulation, or the like.

  Specifically, the adjusting unit 43 changes (adjusts) the opening degrees of the first motor-operated valve 412 and the second motor-operated valve 422, thereby adjusting the discharge amount of the processing liquid W discharged from each of the discharge units 41 and 42. I do. Thereby, the adjustment unit 43 can adjust (change) the inclination of the liquid surface Ws of the processing tank 2.

  In the adjusting unit 43 of the present embodiment, a set of opening degrees (for example, the first motorized valve 412) when the opening degree of each of the motor-operated valves 412 and 422 is set to seven stages (full opening is 7 and fully closing is 1). A set of an opening degree (first valve opening degree) of 3, an opening degree of a second electric valve 422 (second valve opening degree) of 7, a first valve opening degree of 4, and a second valve opening degree of 7, A plurality of sets of the first valve opening 4 and the second valve opening 6 are set.

By changing the opening of the first motor-operated valve 412 and the opening of the second motor-operated valve 422 so as to have any one of the sets, the inclination of the liquid surface Ws of the processing liquid W in the processing tank 2 can be reduced. Adjust so that it is the same plane as the reference plane. This “set of opening degrees” is a processing device similar to the liquid-flow type cloth processing device 1 (for example, without the adjustment unit 43 and the valves of the discharge units 41 and 42 (the first motor-operated valve 412 and the second motor-operated valve). Data obtained by previously processing the fabric C under various conditions using a processing device or the like that can manually change the opening of the valve corresponding to the valve 422) (when the fabric C stably travels along the circulation path). The data is set based on data such as the opening degree of a valve) or simulation.

  The supply unit 44 includes a supply pipe 441 connecting the first and second discharge pipes 411 and 421 and the first end 21, and a processing liquid discharged from the first and second discharge pipes 411 and 421 in the supply pipe 441.

The temperature control unit 443 of this embodiment is a heat exchanger, and controls (changes) the temperature of the processing liquid W by heating or cooling the processing liquid W flowing through the supply pipe 441.

  The liquid level detection unit 5 detects the inclination of the liquid level Ws of the processing liquid W staying in the processing tank 2. The liquid level detection unit 5 of the present embodiment is configured to detect a liquid level position Wp of the processing liquid W at a position spaced in the advancing (moving) direction (left-right direction in FIG. 1) of the cloth C in the main body 23. Of the processing liquid W based on the difference (the difference in the vertical liquid level position) ΔH between the liquid level positions Wp detected by the respective liquid level meters 51 and 52. Detect tilt. Specifically, since the interval (horizontal interval) between the detection positions of the liquid level Ws by the first liquid level meter 51 and the second liquid level meter 52 is determined, the liquid level detection unit 5 From the difference ΔH of the liquid surface position Wp, the inclination of the liquid surface Ws of the processing liquid W in the processing tank 2 is detected.

  Hereinafter, the liquid level gauge 51 for detecting the liquid level position Wp at one end of the main body 23 is referred to as a first liquid level gauge, and the liquid level gauge 52 for detecting the liquid level Wp at the other end of the main body 23 is referred to as a first liquid level gauge. This is referred to as a second level gauge. The first liquid level gauge 51 of the present embodiment detects the liquid level position Wp at or near the connection position of the first discharge section 41 to the main body section 23 in the traveling direction of the fabric C, and the second liquid level gauge 52 The liquid surface position Wp at or near the connection position of the second discharge portion 42 to the main body portion 23 in the traveling direction of the cloth C is detected. Note that the liquid level detection position of the first liquid level meter 51 may be inside the second guide member 26 (cloth side). Further, the detection position of the liquid level of the second liquid level gauge 52 may be inside the first guide member 25 (cloth side).

  In the liquid-flow-type cloth processing apparatus 1 described above, the processing of the cloth C (dyeing in the example of the present embodiment) is performed as follows.

  A long fabric C is carried into the processing tank from the first end 21 in the open state where the opening / closing door 213 is open. The loaded fabric C is inserted into the transfer pipe 3 and connected at both ends to form a loop that can circulate in a circulation path formed by the processing tank 2 and the transfer pipe 3. At this time, the cloth C is wound around the reel 214 of the first end 21.

  When the cloth C is arranged to be able to circulate in the circulation path, the opening / closing door 213 is closed, and the operation (cloth processing) of the liquid-flow type cloth processing apparatus 1 is started. That is, while the pump 442 starts to drive, the reel 214 starts to rotate, whereby the cloth C starts to circulate in the circulation path. At this time, the temperature of the processing liquid W is maintained at, for example, 30 ° C. by the temperature control unit 443.

  The adjusting unit 43 sets the opening degree to be the same as the first set (for example, the first valve opening degree is 3 and the second valve opening degree is 7) among the preset opening degree sets. Then, the opening degree of the first electric valve 412 and the opening degree of the second electric valve 422 are respectively changed (adjusted). Here, the inclination of the liquid level Ws in the processing tank 2 is adjusted so that the cloth C runs stably, and this is set as a reference plane.

  In this state, a chemical or the like is introduced, and the liquid amount increases accordingly. With this change, the inclination of the liquid surface Ws of the processing liquid W tends to change (that is, the cloth C staying in the processing liquid W in the processing tank 2 is biased forward (first end 21 side) or backward ( (The second end 22 side). After that, when the first time (time preset according to the processing content of the cloth C) elapses, the temperature control unit 443 heats the processing liquid W, and sets the temperature of the processing liquid W to, for example, 130 degrees in polyester dyeing. Increase to ° C. Due to the temperature rise of the processing liquid W, at least one of the property of the cloth C, the property of the processing liquid W, and the amount of the processing liquid W stored in the processing tank 2 changes (for example, the softening of the cloth C or the The generation of bubbles (bubbles) in the processing liquid W) causes the inclination of the liquid surface Ws of the processing liquid W to further change (that is, the cloth C staying in the processing liquid W in the processing tank 2). Is biased forward (first end 21 side) or backward (second end 22 side).

  When the inclination of the liquid level Ws starts to change in the processing tank 2, this change is detected by the liquid level detection unit 5, and accordingly, the adjusting unit 43 adjusts the inclination of the liquid level Ws detected by the liquid level detection unit 5. Based on this, the opening of the first motor-operated valve 412 and the opening of the second motor-operated valve 422 are changed so that the liquid level Ws is maintained at the reference surface. In the liquid-flow type cloth processing apparatus 1 of the present embodiment, when the temperature of the processing liquid is increased to, for example, 130 ° C. in the case of polyester dyeing, the adjustment unit 43 sets the second set (for example, , The opening degree of the first motor-operated valve 412 and the opening degree of the second motor-operated valve 422 are respectively changed so as to be the same as the first valve opening degree and the second valve opening degree. . Thereby, even if at least one of the property of the cloth C, the property of the processing liquid W, and the amount of the processing liquid W in the processing tank 2 changes due to the temperature rise, the liquid level Ws of the processing liquid W in the processing tank 2 Is maintained on the reference plane, and stable running of the fabric C is maintained.

  For example, when the temperature of the treatment liquid W rises to 130 ° C. in the case of polyester dyeing and a second time (time preset according to the treatment content of the cloth C) elapses, the temperature control unit 443 subsequently performs processing. The liquid W is cooled to lower the temperature of the processing liquid W to 80 ° C. The inclination of the liquid surface Ws of the processing liquid W also changes due to the change in the property of the cloth C, the property of the processing liquid W, and the amount of the processing liquid W in the processing tank 2 due to the temperature drop of the processing liquid W. try to. Also in this case, when the inclination of the liquid surface Ws starts to change in the processing tank 2, this change is detected by the liquid surface detection unit 5, and the adjusting unit 43 outputs the inclination of the liquid surface Ws detected by the liquid surface detection unit 5. , The opening of the first motor-operated valve 412 and the opening of the second motor-operated valve 422 are changed so that the liquid level Ws is maintained at the reference surface. In the liquid flow type cloth processing apparatus 1 of the present embodiment, when the temperature of the processing liquid is lowered to 80 ° C., the adjusting unit 43 sets the third set (for example, the first valve opening degree) of the opening degree sets. The opening degree of the first motor-operated valve 412 and the opening angle of the second motor-operated valve 422 are respectively changed so that the opening degree becomes the same as the opening degree of the second valve set. Thereby, even if the property of the cloth C, the property of the processing liquid W, and the amount of the processing liquid W in the processing tank 2 change due to the temperature drop, the liquid level Ws of the processing liquid W in the processing tank 2 is set as a reference. Surface, and the stable running of the fabric C is maintained.

  When a third time (time preset according to the processing content of the cloth C) has elapsed since the temperature of the processing liquid W dropped to 80 ° C., the cloth processing ends.

  According to the above-described liquid flow type cloth processing apparatus 1, during operation (during processing of the cloth C), the liquid level Ws of the processing liquid W staying in the processing tank 2 (the main body section 23) is adjusted by the adjusting unit 43 to the reference level. The discharge amount of the processing liquid W from each of the discharge units 41 and 42 is adjusted so that the cloth C stably runs (stably circulates). Thereby, regardless of the skill of the operator (that is, even if the operator does not have the skill, it is not necessary to operate with a small cloth volume to be processed and a large amount of the processing liquid W), so that efficient fabric processing is possible. Becomes possible.

  In the liquid-flow type cloth processing apparatus 1 of the present embodiment, the adjusting unit 43 uses the processing liquid W from each of the discharging units 41 and 42 based on the difference ΔH between the liquid surface positions Wp detected by the pair of liquid level gauges 51 and 52. Emissions are adjusted individually. As described above, the fact that the inclination of a straight line including these two points with respect to the horizontal plane can be obtained from the difference between the horizontal distance and the height of the two points (the liquid level detection positions by the liquid level gauges 51 and 52). A simple configuration, that is, a simple configuration in which a pair (two) of liquid level gauges 51 and 52 are provided so that two liquid level positions Wp spaced apart in the traveling direction (moving direction) of the cloth C can be detected. With the configuration, the inclination of the liquid level Ws of the processing liquid W in the processing tank 2 can be detected with high accuracy.

  In addition, in the liquid-flow type cloth processing apparatus, if the discharge amount of the processing liquid W from each of the discharge units 41 and 42 is not appropriate, the liquid surface balance of the processing liquid W in the processing tank 2 is greatly disturbed. When the liquid level Ws at the connection position with the discharge units 41 and 42 in the inside 2 becomes very low, the discharge units 41 and 42 suck air and the pump 442 does not operate normally. As a result, the cloth C can be circulated. The problem of disappearing occurs. However, in the cloth processing apparatus 1 of the present embodiment, the inclination of the liquid surface Ws is controlled such that the discharge amount of the processing liquid W from the discharge units 41 and 42 is adjusted so that the liquid surface Ws becomes the reference surface. The liquid surface balance in the processing tank 2 is maintained (that is, the liquid surface Ws at the connection position with the discharge units 41 and 42 in the processing tank 2 is prevented from becoming too low), and as a result, the discharge is performed. The portions 41 and 42 can be prevented from sucking air.

  In addition, the liquid-flow-type cloth processing apparatus 1 is not limited to the above-described embodiment, and it is needless to say that various changes can be made without departing from the scope of the present invention. For example, the configuration of one embodiment can be added to the configuration of another embodiment, and a part of the configuration of one embodiment can be replaced with the configuration of another embodiment. Further, a part of the configuration of an embodiment can be deleted.

  In the liquid flow type cloth processing apparatus 1 of the above embodiment, the liquid level detection unit 5 always detects the liquid level Ws from the start to the end of the cloth processing (in the entire range from the low temperature to the high temperature of the processing liquid W). Although the adjustment unit 43 adjusts the discharge amount of the processing liquid W from each of the discharge units 41 and 42 based on this, the present invention is not limited to this configuration. For example, the adjusting unit 43 changes the state of at least one of the property of the cloth C, the property of the processing liquid W, and the amount of the processing liquid W in the processing tank 2 (for example, when the cloth C softens or In a state in which bubbles are generated in W and the fluidity is increased, or in a state where the fluid amount is increased and the fluidity is increased), the liquid surface Ws of the processing liquid W in the processing tank 2 becomes the reference surface. As described above, the configuration may be such that the discharge amount of the processing liquid W from each of the discharge units 41 and 42 is adjusted. As described above, when at least one of the property of the cloth C, the property of the processing liquid W, and the amount of the processing liquid W in the processing tank 2 changes based on the temperature of the processing liquid W, the processing liquid W Since the inclination of the surface Ws is easily changed, the cloth is controlled by controlling the inclination of the liquid surface Ws so that the liquid surface Ws of the processing liquid W becomes the reference surface at least in a state where the properties and the liquid amount are changed. C is easily circulated stably.

  In addition, the adjusting unit 43 discharges the processing liquid W from each of the discharging units 41 and 42 such that the liquid surface Ws of the processing liquid W in the processing tank 2 becomes a reference surface at least at a temperature at which the cloth C softens. The discharge amount of the processing liquid W to be performed may be adjusted. Since the softening (change of properties) of the cloth C most affects the inclination of the liquid level Ws of the processing liquid W, the liquid level Ws of the processing liquid W is set to be the reference plane at least in a state where the cloth C is softened. By controlling the inclination of the liquid surface Ws, the cloth C can be more easily run more stably. Here, the softening (change of properties) of the cloth C is likely to occur when the temperature of the cloth C reaches the glass transition point. For example, when the fabric C is polyester, the property change occurs at about 70 ° C., and when the fabric C is nylon, the property change is about 50 ° C.

  Further, in the liquid flow type cloth processing apparatus 1 of the above embodiment, the opening degree of each of the electric valves 412 and 422 is changed (adjusted) a plurality of times during the processing of the cloth C, but is not limited to this configuration. During the processing of the cloth C, the adjustment unit 43 changes the inclination of the liquid surface Ws (that is, changes in the properties of the cloth C, the properties of the processing liquid W, and the amount of the processing liquid W in the processing tank 2). A configuration in which the degree of opening of each motor-operated valve 412, 422 is changed only once may be used.

  In the liquid flow type cloth processing apparatus 1 of the above embodiment, the opening degree of the first motor-operated valve 412 and the second motor-operated valve 422 is changed (adjusted) in seven stages, but is not limited to this configuration. Each of the motor-operated valves 412 and 422 may have a configuration in which the degree of opening is changed steplessly (continuously).

  In the liquid flow type cloth processing apparatus 1 of the above embodiment, the adjusting unit 43 is configured to perform the first operation so that the opening of each of the motor-operated valves 412 and 422 is the opening of one of a plurality of sets of openings. Although the opening degree of each of the first motor-operated valve 412 and the second motor-operated valve 422 is changed, the present invention is not limited to this configuration. The adjustment unit 43 may be configured to change the opening of each of the motor-operated valves 412 and 422 without using a set of the opening.

  Further, in the liquid-flow type cloth processing apparatus 1 of the above embodiment, the valves provided in the first discharge unit 41 and the second discharge unit 42 are the electric valves 412 and 422, but are not limited to this configuration. The valves provided in the first discharge part 41 and the second discharge part 42 may be any automatic control valves (valves operated by electric signals) such as pneumatically operated automatic valves.

  Further, in the liquid-flow-type cloth processing apparatus 1 of the above embodiment, the discharge amount of the processing liquid W of each of the first discharge unit 41 and the second discharge unit 42 is adjusted, but the present invention is not limited to this configuration. The discharge amount of the processing liquid W in one of the pair of discharge units 41 and 42 may be adjusted. For example, specifically, it is as follows.

  In a state where the opening of the valve 422 of the second discharge unit 42 is fixed (for example, the opening is fixed to 4), the adjusting unit 43 detects the processing liquid W in the processing tank 2 detected by the liquid level detecting unit 5. By adjusting the opening degree of the valve 412 of the first discharge part 41 based on the liquid level Ws (for example, adjusting the opening degree between 1 (fully closed) to 7 (fully open)), the inclination of the liquid level Ws is reduced. Adjustment (control) may be employed. In a state where the opening of the valve 412 of the first discharge unit 41 is fixed, the adjusting unit 43 performs the second operation based on the liquid level Ws of the processing liquid W in the processing tank 2 detected by the liquid level detecting unit 5. The inclination of the liquid level Ws may be adjusted (controlled) by adjusting the opening of the valve 422 of the discharge unit 42.

  In the liquid flow type cloth processing apparatus 1 of the above embodiment, the liquid level detection unit 5 has a pair (two) of liquid level gauges 51 and 52, but the distance is set in the traveling (moving) direction of the cloth C. May be provided with three or more liquid level gauges spaced apart from each other. Thus, the inclination of the liquid surface Ws can be detected with higher accuracy.

  Further, the specific position at which the liquid level meters 51 and 52 detect the liquid level position Wp is not limited. Any position may be used as long as it can detect the inclination of the liquid surface Ws of the processing liquid W in the processing tank 2.

  Further, in the liquid level detection unit 5 of the above embodiment, the difference ΔH between the liquid level positions Wp of the processing liquid W is detected by the liquid level meters 51 and 52, but is not limited to this configuration. For example, the liquid level detection unit 5 may be configured to detect the difference ΔH between the liquid level positions Wp using a pressure sensor or a differential pressure sensor.

  Further, in the liquid-flow type cloth processing apparatus 1 of the above embodiment, when the liquid level Ws detected by one of the two liquid level gauges 51 and 52 is decreased, the other liquid level gauge 52 is set. (Or 51) has a relation that the liquid level Ws detected increases. That is, when the amount of the processing liquid W does not increase or decrease, if one liquid surface Ws is maintained, the other liquid surface Ws is determined, and the reference surface is maintained. For this reason, when the increase and decrease of the processing liquid W in the processing tank 2 is not large, the adjustment unit 43 simply sets the liquid level Ws detected by one liquid level meter 51 or 52 based on the height of the liquid level Ws. The discharge amount of the processing liquid W from each of the discharge units 41 and 42 may be adjusted so that the liquid surface Ws becomes the reference surface.

  Further, in the liquid-flow type cloth processing apparatus 1 of the above embodiment, the set reference plane (the inclination of the liquid level Ws of the processing liquid W) is kept constant during the processing of the cloth C, but is limited to this configuration. Not done. A configuration in which the reference surface changes with time or a temperature range (the inclination of the liquid surface Ws of the processing liquid W changes) may be employed.

  Further, in the liquid-flow type cloth processing apparatus 1 of the above embodiment, a pair (two) of discharge units 41 and 42 are connected to the processing tank 2, but the main body is spaced apart in the traveling (moving) direction of the cloth C. It may have three or more outlets connected to the part 23.

  Further, the specific position where the discharge units 41 and 42 are connected is not limited. Any position can be used as long as the inclination of the liquid surface Ws of the processing liquid W in the processing tank 2 can be adjusted.
