Summary of the Invention
Problems to be Solved by the Invention
[0005] However, in International Publication No. 2022 / 255197, the position of the pressing body relative to the fabric when pressing the fabric is always the same, and a constant pressing force is always applied to the fabric from the pressing body. As a result, depending on the type of fabric, the load on the fabric may become too great, and improvement is desired. Furthermore, in the case of delicate types of fabric, if the pressing force is too great, processing defects (scratches caused by processing) may occur on the surface of the fabric, which is undesirable.
[0006] This invention was made to solve the above-mentioned problems, and one objective of this invention is to provide a liquid flow type fabric processing device and fabric that can change the load on the fabric when pressing the fabric with a pressing body, depending on the type of fabric. [Means for solving the problem]
[0007] The first aspect of this invention is a liquid-flow type fabric processing apparatus that processes fabric with a processing liquid and then washes it with a washing liquid, wherein the processing liquid is retained. ru stagnantA processing tank with a retaining section, a transfer section connected to the processing tank and forming a circulation path for the fabric to circulate together with the processing tank, a turning section in the circulation path that changes the direction of movement of the fabric to face the transfer section, a first pressing body positioned on one side of the fabric moving along the circulation path and pressing the fabric between the retaining section and the turning section to separate the processing liquid contained in the fabric from the fabric, a second pressing body positioned on the other side of the fabric moving along the circulation path and pressing the fabric between the retaining section and the turning section to separate the processing liquid contained in the fabric from the fabric, and during a washing operation in which washing is performed with a washing solution, the first pressing body and The washing machine includes a switching mechanism that moves at least one of the first pressing body and the second pressing body to switch the pressing position for pressing the fabric to multiple positions, wherein when the first pressing body is moved, the pressing positions of the first pressing body include a first pressing position in which the fabric is in contact with the first pressing body and separated from the second pressing body, and a second pressing position in which the fabric pressed by the first pressing body is also brought into contact with the second pressing body so that the fabric is also pressed by the second pressing body, and the switching mechanism is configured to switch the pressing position between the first pressing position and the second pressing position during washing operation by adjusting the position of the first pressing body.
[0008] In the liquid flow type fabric processing apparatus according to the first aspect of this invention, as described above, a first pressing body and a second pressing body are provided to separate the processing liquid contained in the fabric from the fabric by pressing the fabric between a retention section and a deflection section, and a switching mechanism is provided that, during a washing operation in which washing is performed with a washing liquid, moves at least one of the first pressing body and the second pressing body relative to the fabric, thereby switching the pressing position that presses the fabric to multiple positions. This makes it possible to switch the pressing position of at least one of the first pressing body and the second pressing body relative to the fabric according to the type of fabric, such as delicate fabrics that are easily damaged or durable fabrics that are not easily damaged. As a result, the pressing force is not made too large in the case of delicate fabrics, and the occurrence of processing defects (scratches caused by processing) on the surface of the fabric can be suppressed. As a result, the load applied to the fabric when pressing it with the pressing body can be changed depending on the type of fabric. Furthermore, the switching mechanism allows the pressing position of the first pressing body to be switched between the first and second pressing positions. This makes it possible to switch between a state where a large load is applied to the fabric by two pressing bodies and a state where a small load is applied to the fabric by only one pressing body. Therefore, in the case of delicate types of fabric, the pressing force is not made too large, and the occurrence of processing defects (scratches caused by processing) on the surface of the fabric can be further suppressed. As a result, the load on the fabric when pressing it with the pressing bodies can be changed more effectively depending on the type of fabric.
[0010] In the liquid flow type fabric processing apparatus according to the first aspect described above, preferably, when moving the first pressing body, the switching mechanism includes a support arm that supports the first pressing body and a switching drive unit that applies rotational force to the support arm, and is configured to switch the pressing position to multiple positions by rotating the first pressing body via the support arm using the switching drive unit. With this configuration, the pressing position of the first pressing body can be easily switched by rotating the support arm that supports the first pressing body using the switching drive unit to rotate the first pressing body.
[0011] In this case, preferably, the switching drive unit includes an electric cylinder that applies rotational force to the support arm by extending and retracting, or an electric motor configured to have an adjustable output that applies rotational force to the support arm. With this configuration, the electric cylinder or electric motor can be used to easily adjust the pressing position of the first pressing body when switching to multiple positions.
[0012] In a configuration in which the above-described switching drive unit has an electric cylinder or an electric motor, preferably the switching drive unit has an electric cylinder, and the switching mechanism includes an air cylinder connected to the first pressing body that switches the position of the first pressing body from a pressing position to a separated position where the first pressing body is separated from the fabric. With this configuration, vibrations that are applied from the fabric to the first pressing body due to the unevenness of the fabric thickness can be absorbed by having the air cylinder function as an air-type damper.
[0013] In the configuration in which the above-described switching mechanism switches the pressing position between a first pressing position and a second pressing position, preferably, when the first pressing body is moved, the second pressing body is fixed in position so as not to move, and the first pressing body is configured to press the fabric toward the second pressing body when it is in the first pressing position, and to sandwich the fabric between itself and the second pressing body when it is in the second pressing position. With this configuration, the switching mechanism can switch between a state in which the fabric is sandwiched and pressed between the first and second pressing bodies, and a state in which the fabric is pressed only by the first pressing body. As a result, it is possible to switch between a state in which a very large load is applied to the fabric and a state in which a small load is applied to the fabric. As a result, the load on the fabric when it is pressed by the pressing body can be changed more effectively depending on the type of fabric.
[0014] In the above-described switching mechanism, which includes a support arm and a switching drive unit, preferably, the support arm is configured to support both the first and second pressing bodies, the support arm is provided with a pivot axis between the first and second pressing bodies, and the switching drive unit is configured to rotate the first and second pressing bodies simultaneously around the pivot axis by rotating the support arm. With this configuration, both the first and second pressing bodies can be rotated by a simple mechanism consisting of the support arm and the pivot axis.
[0015] In the liquid-flow type fabric processing apparatus according to the first aspect described above, preferably, at least one of the first pressing body and the second pressing body includes a roller member that rotates about a central axis extending in the width direction of the fabric by contacting the moving fabric. With this configuration, the fabric can be moved while the roller member in contact with the fabric is rotated, so that the fabric does not slide against the roller member, and thus damage to the fabric due to sliding resistance can be suppressed. [Effects of the Invention]
[0018] According to the present invention, as described above, depending on the type of fabric, the load on the fabric when pressing the fabric with the pressing body can be changed.

Mode for Carrying Out the Invention
[0020] Hereinafter, embodiments embodying the present invention will be described based on the drawings.
[0021] (First Embodiment) Referring to FIGS. 1 to 10, the configuration of the liquid flow type fabric treatment apparatus 100 according to the first embodiment will be described.
[0022] The liquid flow type fabric treatment apparatus 100 shown in FIG. 1 is an apparatus that performs washing with a cleaning liquid after performing treatment on the fabric C with a treatment liquid. The liquid flow type fabric treatment apparatus 100 is a so-called dyeing machine, and is configured to dye the fabric C with a dyeing liquid as the treatment with the treatment liquid. Specifically, the liquid flow type fabric treatment apparatus 100 impregnates the fabric C with the treatment liquid and places it in a high-temperature state for a certain period of time to dye the fabric C with the dye. The fabric C is a broad concept including woven fabrics, knitted fabrics, non-woven fabrics, and the like.
[0023] Furthermore, the liquid-flow type fabric processing device 100 is configured to wash the fabric C with a washing solution using fresh water, which is unused washing solution. The washing solution may be a washing solution in which a predetermined washing agent is dissolved in fresh water. As a result of washing, any remaining processing solution that has not stained the fabric C is removed from the fabric C.
[0024] The liquid-flow type fabric processing apparatus 100 has an annular circulation path R for circulating fabric C inside. The liquid-flow type fabric processing apparatus 100 is configured to sequentially dye and wash the fabric C while circulating it within the circulation path R. The circulation path R is formed by a processing tank 1 and a transfer pipe 3, which will be described later.
[0025] In each figure, the vertical direction is indicated by the Z direction. Within the Z direction, the upward direction is indicated by the Z1 direction, and the downward direction is indicated by the Z2 direction. In each figure, the longitudinal direction of the liquid-flow type fabric processing device 100, which is perpendicular to the Z direction, is indicated by the X direction. Within the X direction, the direction of movement of the fabric C within the processing tank 1 is indicated by the X1 direction, and the opposite direction is indicated by the X2 direction. Therefore, the X1 direction side is the downstream side of the direction of movement of the fabric C within the processing tank 1, and the X2 direction side is the upstream side of the direction of movement of the fabric C within the processing tank 1. In each figure, the depth direction of the liquid-flow type fabric processing device 100, which is perpendicular to the Z direction and the X direction, is indicated by the Y direction. In each figure, the direction along the inclined surface 122a inside the processing tank 1, which will be described later, is indicated by the A direction.
[0026] As shown in Figure 1, the liquid flow type fabric processing device 100 comprises a processing tank 1, a deflection unit 2, a transfer pipe 3, a washing liquid supply system 4, and a pressing mechanism 5 including a first pressing body 6, a second pressing body 7, and a switching mechanism 8. The transfer pipe 3 is an example of the "transfer unit" of the claims.
[0027] The switching mechanism 8 of the liquid-flow type fabric processing device 100 of the first embodiment is configured to move the first pressing body 6 relative to the fabric C during a washing operation in which washing is performed with a washing solution, and to switch the pressing position P for pressing the fabric C to multiple positions. Details will be described later.
[0028] (Configuration of the treatment tank) As shown in Figure 1, the processing tank 1 includes a first end portion 10, a second end portion 11, and a main body portion 12.
[0029] The first end 10 is the downstream end (X1 direction side) of the fabric C in the direction of movement within the processing tank 1. The second end 11 is the upstream end (X2 direction side) of the fabric C in the direction of movement within the processing tank 1. The main body 12 is the portion between the first end 10 and the second end 11.
[0030] The main body 12 has a cylindrical first inclined portion 121 that slopes slightly downward from the second end 11 toward the first end 10, and a cylindrical second inclined portion 122 that slopes significantly upward from the first inclined portion 121 toward the first end 10. That is, as shown in Figure 1, the main body 12 has a downwardly convex corner 1a between the first inclined portion 121 and the second inclined portion 122 when viewed from the side (from the Y direction). Therefore, the lower part of the second inclined portion 122 of the processing tank 1 is provided with an inclined surface 122a that slopes upward from the corner 1a toward the first end 10 (X1 direction).
[0031] The main body 12 is provided with a retention section 13 for retaining the processing liquid in the processing tank 1. The retention section 13 is generally the portion from the corner 1a towards the second end 11 (towards the X2 direction).
[0032] The processing tank 1 is formed into a hollow structure by connecting multiple members aligned in the X direction. More specifically, as shown in Figure 1, the processing tank 1 includes a main body member 14, a header 15 detachably attached to the main body member 14 from the downstream side (X2 direction side) in the direction of movement of the fabric C, and an additional mounting member 16 that can be attached between the main body member 14 and the header 15. A deflection section 2 is installed in the header 15. Each of the main body member 14, the header 15, and the additional mounting member 16 has a flange portion F that protrudes outward, and is configured to be detachably attached to each other by the flange portion F. In short, the processing tank 1 is formed by the so-called flange connection of the main body member 14, the header 15, and the additional mounting member 16 to each other. The flange portions F are fixed to each other by fixing members (not shown), such as bolts.
[0033] The main body member 14 is located at the uppermost (X2 direction side) of the processing tank 1 in the direction of movement of the fabric C, and has the retention portion 13 and the second end portion 11. The header 15 is located at the lowermost (X1 direction side) of the processing tank 1 in the direction of movement of the fabric C, and has the first end portion 10. The additional attachment member 16 is located between the retention portion 13 and the header 15 in the direction of movement of the fabric C.
[0034] The header 15 is detachably attached to the main body member 14 from the downstream side in the direction of movement of the fabric C. The additional mounting member 16 is configured to be attached between the main body member 14 and the header 15 after the connection between the header 15 and the main body member 14 at the flange portion F is released. This additional mounting member 16 is equipped with a pressing mechanism 5 including a first pressing body 6 and a second pressing body 7. Details of the attachment of the additional mounting member 16 will be described later.
[0035] As shown in Figure 1, a discharge section 17 is provided at the bottom of the processing tank 1. The discharge section 17 is an outlet for discharging the liquid from the processing tank 1 to the outside of the processing tank 1. The discharge section 17 is located between the corner section 1a (stagnation section 13) and the first pressing body 6 and the second pressing body 7. Therefore, the discharge section 17 is located below the first pressing body 6 and the second pressing body 7 in the direction along the inclined surface 122a (direction A).
[0036] The discharge section 17 is configured to discharge the processing liquid separated from the fabric C by the first pressing body 6, preventing it from mixing with other liquids in the processing tank 1. Specifically, the discharge section 17 is positioned closer to the first pressing body 6 and the second pressing body 7 than to the retention area 13. Therefore, the discharge section 17 is configured to discharge the processing liquid outside the processing tank 1 before the processing liquid separated from the fabric C by the first pressing body 6 and the second pressing body 7 reaches the retention area 13. In addition, a wall section 17a is provided between the discharge section 17 on the inclined surface 122a and the retention area 13. The wall section 17a partitions the area of the processing tank 1 between the retention area 13 and the area on the discharge section 17 side, thereby preventing the processing liquid separated from the fabric C from flowing into the retention area 13, and preventing the liquid (mainly cleaning liquid) from the retention area 13 from flowing into the discharge section 17.
[0037] The first end 10 is provided with an openable / closable door 18. The openable / closable door 18 is used when introducing fabric C into the processing tank 1 and when taking fabric C out of the processing tank 1. The openable / closable door 18 is kept closed during dyeing and washing operations of fabric C by the liquid flow type fabric processing device 100.
[0038] The first end 10 is provided with a cylindrical connecting portion 19 that extends downward from the lower part of the first end 10. One end of the transfer pipe 3 (the first upright portion 31, described later) is connected from below to the lower end of the connecting portion 19 provided on the first end 10. The other end of the transfer pipe 3 (the second upright portion 32, described later) is connected from below to the lower part of the second end 11.
[0039] (Structure of the conversion section) The deflection unit 2 is configured to change the direction of movement of the fabric C in the circulation path R so that it faces the transfer pipe 3. In short, the deflection unit 2 is configured to guide the fabric C moving within the processing tank 1 to the transfer pipe 3. The deflection unit 2 is located directly above the connection unit 19. The deflection unit 2 is also located within the processing tank 1 between the opening / closing door 18 and the first pressing body 6 and the second pressing body 7.
[0040] The deflection unit 2 includes an electric motor 20 and a reel 21 that is rotationally driven by the electric motor 20. The reel 21 is configured to pull the fabric C in from the first pressing body 6 and the second pressing body 7 by rotating around a central axis 2a that extends in the width direction of the fabric C while in contact with the fabric C, and to feed the pulled-in fabric C towards the transfer pipe 3 directly below. The reel 21 is composed of a plurality of rod-shaped bodies arranged at equal angular intervals.
[0041] (Configuration of the transfer pipe) The transfer pipe 3 is connected to the main body 12 of the processing tank 1 and, together with the main body 12, forms a circulation path R through which the fabric C can circulate. The transfer pipe 3 is a U-shaped pipe having a main pipe section 30, a first upright section 31, and a second upright section 32.
[0042] The main pipe section 30 extends horizontally (in the X direction) along the processing tank 1 below the processing tank 1. The first upright section 31 extends upward from one end (the end in the X1 direction) of the main pipe section 30 and is connected to the lower part of the connecting section 19 (the first end 10). The second upright section 32 extends upward from the other end (the end in the X2 direction) of the main pipe section 30 and is connected to the lower part of the second end 11.
[0043] (Configuration of the cleaning fluid supply system) The cleaning fluid supply system 4 includes a pump 40 and a pipe 41 for carrying fresh water. The cleaning fluid supply system 4 also includes a fresh fluid supply nozzle 42. The fresh fluid supply nozzle 42 is located inside the connection section 19. The fresh fluid supply nozzle 42 is configured to supply unused cleaning fluid, which is fresh water, to a position downstream of the first and second pressing bodies 6 and 7 in the direction of movement of the fabric C in the circulation path R of the fabric C. The fresh fluid supply nozzle 42 is configured to discharge the unused cleaning fluid at high speed toward the first upright section 31 located diagonally downward from the center inside the connection section 19. The fabric C in the processing tank 1 moves downward toward the transfer pipe 3 along with the unused cleaning fluid discharged at high speed. The fresh fluid supply nozzle 42 is configured to discharge the unused cleaning fluid from almost the entire circumference around the central axis extending vertically in the connection section 19.
[0044] (Configuration of the pressing mechanism) As shown in Figures 1 and 2, the pressing mechanism 5 includes a first pressing body 6, a second pressing body 7 provided separately from the first pressing body 6, and a switching mechanism 8 for switching the position of the first pressing body 6.
[0045] (Configuration of the first pressing body of the pressing mechanism) The first pressing body 6 is positioned below one side of the fabric C as it moves within the processing tank 1. The first pressing body 6 is configured to move by rotating (revolving around a pivot center member 82, described later) within the processing tank 1 via a switching mechanism 8. As shown in the enlarged view of Figure 2, the first pressing body 6 moves by the switching mechanism 8 to contact and separate from the fabric C. The first pressing body 6 is configured to separate the processing liquid contained in the fabric C by pressing the fabric C between the stagnant portion 13 and the deflection portion 2. The processing liquid separated from the fabric C during the washing operation flows down the inclined surface 122a towards the lower discharge portion 17 and is discharged outside the processing tank 1 from the discharge portion 17 of the processing tank 1.
[0046] The first pressing body 6 includes a first rotational central axis 61 and a first roller member 60. The first rotational central axis 61 has a central axis 61a extending in the width direction (Y direction) of the fabric C. The first roller member 60 has a circular outer shape and is supported by the first rotational central axis 61. The first roller member 60 is configured to rotate (rotate) around the central axis 61a by contacting the moving fabric C. That is, the first pressing body 6 is configured to be passively rotated by the moving fabric C. The first pressing body may also be configured to rotate actively by a drive source such as a motor to impart a propulsive force to the fabric to move along a circulation path. The first roller member 60 is an example of the "roller member" in the claims.
[0047] The first roller member 60 has a constant outer diameter at any position in the width direction (Y direction) of the fabric C. However, the first roller member may have a shape different from a constant outer diameter, such as having enlarged diameter sections at both ends in the width direction (Y direction) of the fabric. The first roller member 60 is made of stainless steel (SUS). However, the first roller member may be made of a metal material other than stainless steel, a resin material, or an elastomer material.
[0048] The first roller member 60 is configured to allow the processing liquid to pass through. For example, the first roller member 60 is formed in a porous manner with multiple holes through which the processing liquid separated from the fabric C by pressing can pass. As another example, the first roller member may be formed in an uneven manner that allows the processing liquid to pass through. The first roller member may also have a hollow portion that allows the processing liquid to pass through. Note that the first roller member does not necessarily have to be configured to allow the processing liquid to pass through.
[0049] (Configuration of the second pressing body of the pressing mechanism) The second pressing body 7 is positioned above the other end of the fabric C as it moves within the processing tank 1. Unlike the first pressing body 6, the second pressing body 7 does not rotate (revolve) and its position is fixed so that it does not move within the processing tank 1. The second pressing body 7 is configured to separate the processing liquid contained in the fabric C from the fabric C by pressing the fabric C between the stagnant portion 13 and the deflection portion 2.
[0050] The second pressing body 7 includes a second rotational central axis 71 and a second roller member 70. The second rotational central axis 71 has a central axis 71a extending in the width direction (Y direction) of the fabric C. The second roller member 70 has a circular outer shape and is supported by the second rotational central axis 71. The second roller member 70 is configured to rotate (rotate) around the central axis 71a by contacting the moving fabric C. That is, the second pressing body 7 is configured to be passively rotated by the moving fabric C. The second pressing body may also be configured to rotate actively by a drive source such as a motor to impart a propulsive force to the fabric to move along a circulation path. The second roller member 70 is an example of the "roller member" of the claims.
[0051] Since the second roller member 70 of the second pressing body 7 is formed with the same shape and material as the second roller member 70 of the first pressing body 6 described above, no further explanation of the second pressing body 7 will be provided.
[0052] Here, flange portions 62 (see Figure 9) are provided at both ends of the first roller member 60 in the direction (Y direction) in which the central axis 61a extends from the first roller member 60, projecting radially outward from the first roller member 60. The flange portions 62 (first pressing body 6) are configured to contact an internal stopper 72 (see Figure 9) located in the processing tank 1, thereby restricting their movement. As a result, direct contact between the first roller member 60 and the second roller member 70 is prevented. The internal stopper 72 is provided on the second rotational central axis 71. Further details will be described later.
[0053] (Configuration of the switching mechanism for the pressing mechanism) The configuration of the switching mechanism 8 will be explained with reference to Figures 2 to 8. As described above, the switching mechanism 8 is configured to move the first pressing body 6 relative to the fabric C and switch the pressing position P for pressing the fabric C to multiple positions. The pressing position P of the first pressing body 6 includes a first pressing position P1 (see Figures 5 and 6) and a second pressing position P2 (see Figures 7 and 8). The first pressing position P1 is the position of the first pressing body 6 that separates the fabric C from the second pressing body 7. The second pressing position P2 is the position of the first pressing body 6 that brings the fabric C, which has been pressed by the first pressing body 6, into contact with the second pressing body 7 so that the fabric C is also pressed by the second pressing body 7.
[0054] The switching mechanism 8 is configured to switch the pressing position P of the first pressing body 6 between the first pressing position P1 and the second pressing position P2 during the washing operation. Note that "during the washing operation" is a broad concept that includes the timing before (immediately before) and after (immediately after) the washing operation. Furthermore, the switching mechanism 8 is also configured to switch the position of the first pressing body 6 from the pressing position P to the separated position S (see Figures 3 and 4) where the first pressing body 6 is separated from the fabric C.
[0055] At the first pressing position P1, only the first pressing body 6 presses against the fabric C. At the second pressing position P2, both the first pressing body 6 and the second pressing body 7 press against the fabric C. At the separated position S, both the first pressing body 6 and the second pressing body 7 move away from the fabric C.
[0056] The switching mechanism 8 switches the position of the first pressing body 6 from the separated position S to the pressed position P (first pressed position P1 or second pressed position P2) before (immediately before) the start of the cleaning operation. During the execution of the cleaning operation, the position of the first pressing body 6 is maintained at the pressed position P. In principle, the switching mechanism 8 does not switch the position of the first pressing body 6 from the pressed position P to any other pressed position P during the cleaning operation. In other words, the electric cylinder 84, which will be described later, does not extend or retract during the cleaning operation. Then, after (immediately after) the end of the cleaning operation, the switching mechanism 8 switches the position of the first pressing body 6 from the pressed position P to the separated position S. As stated above, "before the start of the cleaning operation" and "after the end of the cleaning operation" are included in "during the cleaning operation". The specific configuration of the switching mechanism 8 will be described below. The electric cylinder 84 is an example of the "switching drive unit" in the claims.
[0057] As shown in Figure 2, the switching mechanism 8 includes an air cylinder 80 and an electric cylinder 84 that generate a driving force (rotational force) to move the first pressing body 6, a link member 81, a pivot center member 82, and a support arm 83 that supports the first pressing body 6.
[0058] The air cylinder 80 is connected to the first pressing body 6 via a link member 81, a pivot center member 82, and a support arm 83. The driving force of the air cylinder 80 is transmitted to the first pressing body 6 in the order of link member 81, pivot center member 82, and support arm 83. The air cylinder 80 is configured to switch the position of the first pressing body 6 from a pressing position P to a separated position S. The air cylinder 80 is also configured to switch the position of the first pressing body 6 from the separated position S to a pressing position P.
[0059] The pivoting center member 82 extends from the outside to the inside of the processing tank 1 along the width direction (Y direction) of the fabric C. That is, the pivoting center member 82 penetrates the side wall of the processing tank 1. The pivoting center member 82 is installed so as not to move relative to the processing tank 1, while being rotatable around a central axis 82a extending in the width direction (Y direction) of the fabric C. In a side view (viewed from the Y direction), the pivoting center member 82 is positioned closer to the corner 1a (towards the X2 direction) (see Figure 1) than the first pressing body 6 and the second pressing body 7.
[0060] The air cylinder 80, the electric cylinder 84, and the link member 81 are located outside the processing tank 1. The support arm 83 is located inside the processing tank 1. One end of the link member 81 is rotatably connected to the tip (upper end) of the cylinder rod 80a of the air cylinder 80. The air cylinder 80 is located below the link member 81 so that the extension of the cylinder rod 80a pushes the link member 81 upward from below. Conversely, the electric cylinder 84 is located above the link member 81 so that the extension of the cylinder rod 84a pushes the link member 81 downward from above.
[0061] The air cylinder 80 is configured to extend and retract its cylinder rod 80a in a direction perpendicular to the width direction (Y direction) of the fabric C. The air cylinder 80 is configured to extend and retract in two stages: an extended state and a retracted state. When the air cylinder 80 is in the extended state, the first pressing body 6 is positioned at the pressing position P (first pressing position P1 or second pressing position P2). When the air cylinder 80 is in the retracted state, the first pressing body 6 is positioned at the separated position S.
[0062] As shown in Figure 4, the air cylinder 80 is installed in the processing tank 1 via bracket B. More specifically, the body of the air cylinder 80 is installed in a rotatable manner relative to the processing tank 1 by bracket B, and its orientation relative to the processing tank 1 changes in a side view as the cylinder rod 80a extends and retracts (as the link member 81 rotates around the central axis 82a).
[0063] The tip (lower end) of the cylinder rod 84a of the electric cylinder 84 is maintained in contact with the upper surface of the link member 81 (see Figures 5 to 8) when the air cylinder 80 is extended. That is, the tip of the cylinder rod 84a is maintained in contact with the upper surface of the link member 81 when the first pressing body 6 is in the pressing position P. Also, when the air cylinder 80 is retracted, the tip of the cylinder rod 84a is maintained in a state separated from the upper surface of the link member 81 (see Figures 3 and 4). That is, the tip of the cylinder rod 84a is maintained in a state separated from the upper surface of the link member 81 when the first pressing body 6 is in the separated position S.
[0064] As shown in Figure 2, the electric cylinder 84 is configured to apply rotational force (torque) to the support arm 83. The switching mechanism 8 is configured to switch the pressing position P to multiple positions by rotating the first pressing body 6 via the support arm 83 using the electric cylinder 84. The electric cylinder 84 is configured to restrict the extension of the air cylinder 80 located below the link member 81 from above the link member 81. The electric cylinder 84 is configured to switch the pressing position P to multiple positions by extending and retracting, thereby changing the limit on the stroke length of the extended air cylinder 80.
[0065] The phrase "switching the pressing position P to multiple positions" above means not only switching between the first pressing position P1 and the second pressing position P2, but also switching so that the distance between the first pressing body 6 and the second pressing body 7 changes at the first pressing position P1. Specifically, by changing the protruding length L1 of the cylinder rod 84a when the first pressing body 6 is located at the first pressing position P1, as shown in Figure 6, to a range greater than the protruding length L2 of the cylinder rod 84a when the first pressing body 6 is located at the second pressing position P2, as shown in Figure 8, it is possible to switch the first pressing position P1 of the first pressing body 6 to multiple positions.
[0066] Thus, the electric cylinder 84 functions as a stopper that determines the maximum stroke length of the air cylinder 80 by limiting the stroke length of the air cylinder 80 when it is extended. When the air cylinder 80 is extended, as the electric cylinder 84 extends and its protruding length L1 (see Figure 6) increases, the distance between the first pressing body 6 and the second pressing body 7 gradually increases, but the position of the first pressing body 6 does not switch from the pressing position P to the separated position S.
[0067] The link member 81 extends linearly outside the processing tank 1 in a direction perpendicular to the width direction (Y direction) of the fabric C. The other end of the link member 81 is fixed to the outer end of the pivot center member 82, which is located outside the processing tank 1.
[0068] One end of a support arm 83 is fixed to the inner end of a pivot center member 82 located inside the processing tank 1. The support arm 83 extends linearly inside the processing tank 1 in a direction perpendicular to the width direction (Y direction) of the fabric C. The other end of the support arm 83 supports the first pressing body 6. The first rotational axis 61 of the first pressing body 6 is fixed to the support arm 83. The support arm 83 is provided at least on one end of the first pressing body 6 in the width direction (Y direction) of the fabric C so as not to interfere with the fabric C. The link member 81, the pivot center member 82, the support arm 83, and the first rotational axis 61 of the first pressing body 6 are fixed to each other and are configured to operate as a single unit.
[0069] With the first pressing body 6 in the separated position S as shown in Figures 3 and 4, the switching mechanism 8 extends the air cylinder 80 upward and presses one end of the link member 81 upward (changing from a retracted state to an extended state). This converts the pressing force of the air cylinder 80 into rotational force (torque) that rotates the first pressing body 6 via the link member 81, the pivoting center member 82, and the support arm 83. As a result, the first pressing body 6 rotates around the central axis 82a of the pivoting center member 82 to approach the second pressing body 7 (rotating in the direction of the black-colored arrow shown in Figure 2), and the position of the first pressing body 6 switches from the separated position S to the pressing position P.
[0070] As shown in Figures 5 to 8, when the first pressing body 6 is in the pressing position P (when the air cylinder 80 is extended), the stroke length of the air cylinder 80 is limited and determined by the electric cylinder 84 located above the air cylinder 80. In this state, the electric cylinder 84 is configured to switch the pressing position P, including the first pressing position P1 and the second pressing position P2, to multiple positions by extending and retracting and changing the amount of limitation on the stroke length of the air cylinder 80. When the first pressing body 6 is in the first pressing position P1, it is configured to press the fabric C against the second pressing body 7 by itself, and when it is in the second pressing position P2, it is configured to sandwich the fabric C between itself and the second pressing body 7.
[0071] With the first pressing body 6, as shown in Figures 5 and 7, in the pressing position P, the switching mechanism 8 retracts the air cylinder 80 and pulls one end of the link member 81 downward (from extended to retracted), thereby rotating the first pressing body 6 around the central axis 82a of the pivoting center member 82 so that it moves away from the second pressing body 7 (rotating in the direction of the white-painted arrow shown in Figure 2), and switching the position of the first pressing body 6 from the pressing position P to the separated position S. The air cylinder 80 is driven by operating a switch provided on the control panel (not shown) of the liquid-flow type fabric processing device 100, or by automatic control.
[0072] (Configuration to prevent contact between the first roller member and the second roller member) Next, referring to Figure 9, a configuration for preventing contact between the first roller member 60 of the first pressing body 6 and the second roller member 70 of the second pressing body 7 will be described. Prevention of contact between the first roller member 60 and the second roller member 70 is achieved by a flange portion 62 provided on the first roller member 60 and an internal stopper 72 provided on the second rotational central axis 71.
[0073] In the first embodiment of the liquid-flow type fabric processing device 100, the internal stopper 72 has a cylindrical shape and the second rotational central axis 71 is inserted through it. The flange portion 62 is positioned in the width direction (Y direction) of the fabric C, corresponding to the internal stopper 72. When the fabric C is not installed in the liquid-flow type fabric processing device 100, if the user accidentally extends the air cylinder 80 and switches the position of the first pressing body 6 from the separated position S to the pressing position P, the flange portion 62 and the internal stopper 72 come into contact with each other, separating the first roller member 60 and the second roller member 70 by a minimum gap D, thereby restricting the movement of the first roller member 60 (first pressing body 6). As a result, contact between the first roller member 60 and the second roller member 70 is avoided. Therefore, the surfaces of the first roller member 60 and the second roller member 70 that press the fabric are not damaged.
[0074] The liquid-flow type fabric processing apparatus 100 described above produces fabric C that has been processed with a processing solution (dyeing solution) and washed. Specifically, it comprises a processing tank 1 equipped with a retention section 13 (see Figure 1) for retaining the processing solution of fabric C, a transfer pipe 3 connected to the processing tank 1 and forming a circulation path R through which fabric C can circulate together with the processing tank 1, a deflection section 2 in the circulation path R that changes the direction of movement of fabric C to face the transfer pipe 3, and a first press positioned on one side of fabric C moving along the circulation path R that presses fabric C between the retention section 13 and the deflection section 2 to separate the processing solution contained in fabric C from fabric C. A liquid-flow type fabric processing apparatus 100 is provided, comprising a pressure body 6, a second pressure body 7 positioned on the other side of the fabric C moving along the circulation path R, which presses the fabric C between the stagnant portion 13 and the deflection portion 2 to separate the processing liquid contained in the fabric C from the fabric C, and a switching mechanism 8 that, during a washing operation in which washing is performed with a washing liquid, moves the first pressure body 6 relative to the fabric C to switch the pressing position P for pressing the fabric C to multiple positions. Through this apparatus, a fabric C that has been processed with a processing liquid and washed is produced.
[0075] The installation of the additional mounting member 16 will be explained with reference to Figures 1 and 10. Figure 10 shows a device configuration without the additional mounting member 16, while Figure 1 shows a device configuration with the additional mounting member 16. In the device configuration shown in Figure 10, the header 15 and the main body member 14 are directly connected via a flange portion F. The connection between the header 15 and the main body member 14 via the flange portion F is then released, and the additional mounting member 16, which is provided with the first pressing body 6 and the second pressing body 7, is inserted between the header 15 and the main body member 14. As a result, it is possible to change from the device configuration shown in Figure 10 to the device configuration shown in Figure 1, which includes the additional mounting member 16 provided with the first pressing body 6 and the second pressing body 7. Therefore, if a user is using a liquid-flow type fabric processing device that does not have a pressing mechanism 5, it is possible to add the function of the pressing mechanism 5 to the liquid-flow type fabric processing device 100 by retrofitting the additional mounting member 16 between the main body member 14 and the header 15.
[0076] (Effects of the first embodiment) In the first embodiment, the following effects can be obtained.
[0077] In the first embodiment, as described above, a first pressing body 6 and a second pressing body 7 are provided to press the fabric C between the retention portion 13 and the deflection portion 2 to separate the processing liquid contained in the fabric C from the fabric C, and a switching mechanism 8 is provided that, during a washing operation in which washing is performed with a washing liquid, moves at least one of the first pressing body 6 and the second pressing body 7 relative to the fabric C to switch the pressing position P for pressing the fabric C to multiple positions. This makes it possible to switch the pressing position P for at least one of the first pressing body 6 and the second pressing body 7 relative to the fabric C according to the type of fabric C, such as a delicate fabric C that is easily damaged or a durable fabric C that is not easily damaged. Therefore, in the case of a delicate type of fabric C, the pressing force is not made too large, and the occurrence of processing defects (scratches caused by processing) on the surface of the fabric C can be suppressed. As a result, the load applied to the fabric C when it is pressed by the pressing body can be changed depending on the type of fabric C.
[0078] In the first embodiment, as described above, when the first pressing body 6 is moved, the pressing position P of the first pressing body 6 includes a first pressing position P1 that separates the fabric C from the second pressing body 7, and a second pressing position P2 that brings the fabric C pressed by the first pressing body 6 into contact with the second pressing body 7 so that the fabric C is also pressed by the second pressing body 7. The switching mechanism 8 is configured to switch the pressing position P between the first pressing position P1 and the second pressing position P2 during the washing operation. As a result, the switching mechanism 8 can switch the pressing position P of the first pressing body 6 between the first pressing position P1 and the second pressing position P2, so that a state in which a large load is applied to the fabric C by two pressing bodies and a state in which a small load is applied to the fabric C by only one pressing body can be switched. Therefore, in the case of delicate types of fabric C, the pressing force can be kept from being too large, thereby further suppressing the occurrence of processing defects (scratches caused by processing) on the surface of fabric C. As a result, the load on fabric C when pressing it with the pressing body can be changed more effectively depending on the type of fabric C.
[0079] In the first embodiment, as described above, when moving the first pressing body 6, the switching mechanism 8 includes a support arm 83 that supports the first pressing body 6 and a switching drive unit (electric cylinder 84) that applies rotational force to the support arm 83. The switching drive unit rotates the first pressing body 6 via the support arm 83, thereby switching the pressing position P to multiple positions. This makes it possible to easily switch the pressing position P of the first pressing body 6 by rotating the support arm 83 that supports the first pressing body 6 with the switching drive unit, thereby rotating the first pressing body 6.
[0080] In the first embodiment, as described above, the switching drive unit has an electric cylinder 84 that applies rotational force to the support arm 83 by extending and retracting. This makes it easy to adjust the pressing position P of the first pressing body 6 when switching to multiple positions using the electric cylinder 84.
[0081] In the first embodiment, as described above, the switching mechanism 8 includes an air cylinder 80 connected to the first pressing body 6, which switches the position of the first pressing body 6 from a pressing position P to a separated position S in which the first pressing body 6 is separated from the fabric C. This allows vibrations applied from the fabric C to the first pressing body 6 due to the uneven thickness of the fabric C to be absorbed by having the air cylinder 80 function as an air-type damper.
[0082] In the first embodiment, as described above, when the first pressing body 6 is moved, the second pressing body 7 is fixed in position so as not to move. The first pressing body 6 is configured to press the fabric C toward the second pressing body 7 when it is located at the first pressing position P1, and to sandwich the fabric C between the first pressing body 6 and the second pressing body 7 when it is located at the second pressing position P2. This allows the switching mechanism 8 to switch between a state in which the fabric C is sandwiched and pressed between the first pressing body 6 and the second pressing body 7, and a state in which the fabric C is pressed only by the first pressing body 6. As a result, it is possible to switch between a state in which a very large load is applied to the fabric C and a state in which a small load is applied to the fabric C. As a result, the load on the fabric C when it is pressed by the pressing body can be changed more effectively depending on the type of fabric C.
[0083] In the first embodiment, as described above, at least one of the first pressing body 6 and the second pressing body 7 includes a first roller member 60 and a second roller member 70 that rotate around a central axis extending in the width direction of the fabric C by contacting the moving fabric C. This prevents the fabric from sliding against the first roller member 60 and the second roller member 70, thereby preventing damage to the fabric C due to sliding resistance.
[0084] (Second Embodiment) Next, with reference to Figures 11 to 15, the liquid flow type fabric processing apparatus 200 of the second embodiment will be described. Unlike the configuration of the first embodiment described above, in which only the position of the first pressing body 6 is switched by the switching mechanism 8, the second embodiment will describe an example in which the positions of both the first pressing body 6 and the second pressing body 7 are switched by the switching mechanism 208. In the second embodiment, components similar to those of the first embodiment are denoted by the same reference numerals and their description is omitted.
[0085] The liquid-flow type fabric processing apparatus 200 of the second embodiment includes a switching mechanism 208 for switching the positions of the first pressing body 6 and the second pressing body 7. The switching mechanism 208 is configured to move (rotate) the first pressing body 6 and the second pressing body 7 relative to the fabric C during the washing operation, thereby switching the pressing position P for pressing the fabric C to multiple positions.
[0086] The switching mechanism 208 includes an electric motor 284 having an output gear 284a and a support arm 283 that supports both the first press body 6 and the second press body 7. The electric motor 284 is an example of the “switching drive unit” of the claims.
[0087] The support arm 283 is a rod-shaped member that extends vertically perpendicular to the direction along the inclined surface 122a (direction A). A first pressing body 6 and a second pressing body 7 are fixed to one end and the other end of the support arm 283, respectively. The support arm 283 is provided with a pivot axis 282 between the first pressing body 6 and the second pressing body 7. The pivot axis 282 has a driven gear 282a that meshes with the output gear 284a. When the output gear 284a rotates, the pivot axis 282 also rotates together with the driven gear 282a.
[0088] The electric motor 284 is located on the outside of the processing tank 1. The pivot axis 282 extends from the outside to the inside of the processing tank 1 along the width direction (Y direction) of the fabric C. That is, the pivot axis 282 penetrates the side wall of the processing tank 1. A driven gear 282a is located at the outer end of the pivot axis 282, which is located on the outside of the processing tank 1. A support arm 283 is fixed to the inner end of the pivot axis 282, which is located on the inside of the processing tank 1.
[0089] The electric motor 284 is configured to have an adjustable output and to impart rotational force to the support arm 283. For example, the electric motor 284 is configured as a stepping motor. The electric motor 284 is configured to rotate the support arm 283, thereby simultaneously rotating the first pressing body 6 and the second pressing body 7 around the pivot axis 282.
[0090] In detail, in Figures 11 and 12, the first pressing body 6 and the second pressing body 7 are spaced apart from the fabric C. The first pressing body 6 is positioned above the fabric C, and the second pressing body 7 is positioned below it. From this state, as shown in Figures 12 and 13, the electric motor 284 can rotate the first pressing body 6 and the second pressing body 7 simultaneously to switch to a state where only the first pressing body 6 is in contact with the fabric C. In this state, the pressing force exerted by the first pressing body 6 on the fabric C is relatively small.
[0091] As shown in Figure 14, the electric motor 284 can further rotate the first and second pressing bodies 6 and 7 to switch to a state where both the first and second pressing bodies 7 are in contact with the fabric C. In this state, the pressing force exerted by the first and second pressing bodies 6 and 7 on the fabric C is relatively large. In the first embodiment, it was not possible to move the first pressing body 6 with the electric cylinder 84 while maintaining the state in which both the first and second pressing bodies 6 and 7 were in contact with the fabric C, but in the second embodiment, it is possible to further move the first pressing body 6 with the electric motor 284.
[0092] In detail, the electric motor 284 can move the first and second pressing bodies 6 and 7 to a position where the fabric C is in a Z shape by further rotating them. In this state, the pressing force exerted by the first and second pressing bodies 6 and 7 on the fabric C becomes even greater.
[0093] (Effects of the second embodiment) In the second embodiment, the following effects can be obtained.
[0094] In the second embodiment, as described above, a first pressing body 6 and a second pressing body 7 are provided to press the fabric C between the retention portion 13 and the deflection portion 2 to separate the processing liquid contained in the fabric C from the fabric C, and a switching mechanism 208 is provided that, during a washing operation in which washing is performed with a washing liquid, moves at least one of the first pressing body 6 and the second pressing body 7 relative to the fabric C to switch the pressing position P for pressing the fabric C to multiple positions. This makes it possible to change the load on the fabric C when the fabric C is pressed by the pressing body, according to the type of fabric C, as in the first embodiment.
[0095] In the second embodiment, as described above, the switching drive unit has an electric motor 284 that is configured to have an adjustable output and provides rotational force to the support arm 283. This makes it easy to adjust the pressing position P of the first pressing body 6 when switching to multiple positions using the electric motor 284.
[0096] In the second embodiment, as described above, the support arm 283 is configured to support both the first pressing body 6 and the second pressing body 7. The support arm 283 is provided with a pivot axis 282 between the first pressing body 6 and the second pressing body 7, and the electric motor 284 is configured to rotate the support arm 283, thereby simultaneously rotating the first pressing body 6 and the second pressing body 7 around the pivot axis 282. This allows both the first pressing body 6 and the second pressing body 7 to be rotated by a simple mechanism consisting of the support arm 283 and the pivot axis 282.
[0097] [Differentiation] It should be noted that the embodiments disclosed herein are illustrative and not restrictive in all respects. The scope of the present invention is indicated by the claims rather than by the description of the embodiments above, and further includes all modifications (exceptions) within the meaning and scope of the claims.
[0098] For example, the first embodiment described above shows an example in which the position of the first pressing body in the pressing position is moved by an electric cylinder, but the present invention is not limited thereto. In the present invention, as in the first modified example liquid flow type fabric processing device 300 shown in Figure 16, the position of the first pressing body 6 (see Figure 1) in the pressing position P may be moved by an adjustment bolt 384. The adjustment bolt 384 is installed in the processing tank 1 above the link member 81. The processing tank 1 is provided with an installation part 384a having a screw hole for installing the adjustment bolt 384. When the first pressing body 6 is in the pressing position P, the lower end of the adjustment bolt 384 is in contact with the upper surface of the link member 81. The adjustment bolt 384 is configured to switch the pressing position P of the first pressing body 6 to multiple positions by adjusting the amount of screwing into the installation part 384a, thereby pressing and rotating the link member 81 from above.
[0099] Furthermore, while the first and second embodiments described above show an example in which the processing tank is composed of three components: a main body component, a header, and an additional mounting component, the present invention is not limited thereto. In the present invention, the processing tank 401 may be composed of two components: a main body component 14 and a replaceable mounting component 415, as shown in the second modified example of the liquid flow type fabric processing device 400 in Figure 17. In this second modified example, as shown in Figure 17, the replaceable mounting component 415 is equipped with a deflection section 2 and a pressing mechanism 5 (first pressing body 6 and second pressing body 7). This replaceable mounting component 415 corresponds to a configuration in which the header 15 and the additional mounting component 16 of the first embodiment are combined into a single component. The replacement mounting member 415 is configured to be attached to the main body member 14 from the downstream side in the direction of movement of the fabric C, instead of the header 15 (see Figure 10), which includes a deflection section 2 and is detachably attached to the main body member 14 from the downstream side in the direction of movement of the fabric C. This makes it possible for a user to equip the liquid-flow type fabric processing device 400 with the function of the pressing mechanism 5 simply by replacing the header 15 with the replacement mounting member 415, when the user is using a liquid-flow type fabric processing device that does not have a pressing mechanism 5.
[0100] Furthermore, while the first embodiment described above shows an example in which a flange is provided on the first roller member of the first pressing body and an internal stopper is provided on the second rotational axis of the second pressing body, the present invention is not limited thereto. In the present invention, the flange and internal stopper may be omitted, as in the third modified example liquid flow type fabric processing device 500 shown in Figure 18. In this case, the stroke length of the air cylinder 80 can usually be limited by the electric cylinder 84 to avoid contact between the first roller member 60 and the second roller member 70, but in cases such as when the electric cylinder 84 is not adjusted, the first roller member 60 and the second roller member 70 may come into contact. For this reason, the liquid flow type fabric processing device 100 of the first embodiment described above is preferred over the third modified example liquid flow type fabric processing device 500.
[0101] Furthermore, although the first embodiment described above shows an example in which the first pressing body is moved on the underside of the fabric, the present invention is not limited to this. In the present invention, the first pressing body may be moved on the upper side of the fabric.
[0102] Furthermore, although the first embodiment described above shows an example in which only the first pressing body is moved, the present invention is not limited thereto. In the present invention, only the second pressing body may be moved.
[0103] Furthermore, in the second embodiment described above, an example was shown in which the first pressing body, located above the fabric, was brought into contact with the fabric first, starting from a state in which both the first and second pressing bodies were separated from the fabric. However, the present invention is not limited to this. In the present invention, starting from a state in which both the first and second pressing bodies were separated from the fabric, the second pressing body, located below the fabric, may be brought into contact with the fabric first. Alternatively, starting from a state in which both the first and second pressing bodies were separated from the fabric, the first and second pressing bodies may be brought into contact with the fabric simultaneously.
[0104] Furthermore, although the first embodiment described above shows an example in which the first pressing body is moved by an electric cylinder and an air cylinder, the present invention is not limited thereto. In the present invention, the first pressing body may be moved by an electric cylinder alone. In addition, the first pressing body may be moved by a stepping motor or the like.
[0105] Furthermore, although the first embodiment described above shows an example in which the first and second pressing bodies are moved by an electric motor, the present invention is not limited to this. In the present invention, the first and second pressing bodies may be moved by an electric cylinder or the like. [Explanation of Symbols]
