[0001] Device and method for treating textiles or leather
[0002] The present invention relates to a device suitable for use in treating textiles or leather, and to a method for treating textiles or leather that can be carried out using the device. The method can be the washing and / or dyeing of textiles or leather. The textiles or leather treated by the method can be clothing, which can be finished or semi-finished, or uncut or web-shaped or cut textiles or leather. The textiles can comprise cotton, wool, synthetic fiber, flax, or a combination of at least two of these, and the leather can be raw or at least partially tanned. The method can comprise the tanning and / or dyeing of leather.
[0003] It is generally known to rotate a perforated drum in a container around a horizontal axis in order to treat textiles or leather with liquids contained in the container. DE 10 2013 109 482 A1 describes a drum for the wet treatment of textiles that is driven to rotate around a vertical axis. A conduit is attached to the drum. One end of the conduit opens into an annular channel attached to the drum, which radially surrounds the drum, and the other end opens closer to the axis.
[0004] US 1 981 453 A describes the conveying of liquid through textiles that are in contact with the wall of a rotating container, whereby the liquid is fed centrally into the container and, after passing through the textiles, exits through openings in the container wall.
[0005] WO 98 / 07057 A1 describes mixing by moving a container along a movement path with two regions of strong path curvature or two reversal points.
[0006] DE 10 2018 215 084 A1 describes the back and forth movement of a container containing the components of the mass along two axes, each with a different frequency, in order to produce a mass which has a continuous homogeneous phase.
[0007] The object of the invention is to provide an alternative device and a method for treating textiles or leather that can be carried out using a small volume of liquid.
[0008] The invention solves the problem with the features of the claims and in particular with a device for use in the treatment of textiles or leather with liquid, wherein the device comprises a container with an optional inner wall having through holes and surrounded by a spaced outer wall, wherein the inner wall is preferably firmly connected to the outer wall, with lids that cover the terminal cross-sectional openings of the container, optionally with at least one movable line connected to the container, which is connected to at least one of the lids, optionally to the intermediate space formed between the inner wall and the outer wall spaced therefrom, a drive that is configured to drive the container along a trajectory curve to a reciprocating movement, wherein the plane in which the trajectory curve extends and in which the container is moved is preferably parallel to the cross section of the container,- and the drive is designed to move the container with a maximum acceleration of at least 20 m / s, 2 , preferably at least 30 m / s 2 or at least 50 m / s 2 or at least 100 m / s 2 , e.g. up to 600 m / s each 2 or up to 500 m / s 2 to move along the trajectory curve, wherein optionally the device is arranged not to rotate the container during the movement along the trajectories, in particular not to rotate it about an axis perpendicular to the plane of the trajectories,
[0009] - wherein optionally the device is arranged, when the drive for movement along the trajectory does not move the container, to drive the container, e.g. by a second drive, for rotation about an axis perpendicular to the plane of the trajectory, has or consists thereof.
[0010] The inner wall is preferably cylindrical, with its cross-section parallel to the plane of the trajectories; optionally, the inner wall has a hexagonal, octagonal, decagonal, dodecagonal, or polygonal cross-section. The inner wall defines the container interior. The terminal cross-sectional openings of the container interior, preferably including the terminal cross-sectional openings of the outer wall, are closed with lids, which are preferably parallel to the plane of the cross-section defined by the inner wall.
[0011] The distance between the outer wall and the inner wall is preferably 1 to 20 mm, more preferably 1 to 10 mm or up to 5 mm, e.g. 2 to 4 mm. The small distance between the inner and outer walls results in a small dead volume into which liquid can enter through the through-holes in the inner wall. From this dead volume, which is limited by the distance between the inner and outer walls, liquid can be withdrawn through an optionally connected line, the container can be evacuated, or liquid or air, in particular air heated to e.g. 50 to 90°C, can be pumped into the container through the line.
[0012] Preferably, the cross section spanned by the inner wall has a diameter that is 0.5 times to 2 times the extension along the longitudinal axis that is perpendicular to the cross section.
[0013] Textiles and leather are also referred to as fabrics here. The cross-section results in a relative movement of the materials filled into the container against the container wall during the reciprocating movement along a trajectory curve, which can be achieved, for example, by reciprocating along at least two axes that are at an angle to each other and in the plane of the container's cross-section. It is assumed that the intensive and effective penetration of the materials with liquid during the process is due to the fact that the movement of the container accelerates the materials contained therein relative to the inner wall by more than 1 xg (gravitational acceleration).
[0014] The container is driven to reciprocate along at least one trajectory curve, which can be generated by superimposing the reciprocation along at least two axes that are at an angle to each other, wherein preferably two of the axes lie in the plane of the cross-section of the container, wherein the reciprocation along each axis occurs at different frequencies and / or with a phase offset.The trajectory curve can be generated by superimposing the reciprocating motion along two or three axes at different frequencies and / or with a phase shift, and comprises a sequence of trajectory segments, of which at least one, preferably each, comprises or consists of exactly one complete reciprocating motion along the axis along which the reciprocating motion occurs at the lower frequency, wherein the superimposed reciprocating motions at the higher frequency or the same frequency, each optionally with a phase shift, are included along the other axis or axes. The lower frequency of the complete reciprocating motion forms the frequency of the sequence of trajectory segments.For each track segment, a frequency ratio of the reciprocating movement along two axes of a maximum of 1:20 or a maximum of 1:15 or a maximum of 1:10, a maximum of 1:4 or a maximum of 1:3 is preferred, more preferably between 1:1 and 1:2, even more preferably greater than 1:1 and up to 1:2 or up to 1:1.5, e.g. with a frequency ratio of 1:1.001 and up to 1:2 or up to 1:1.5.
[0015] For a trajectory that can be generated by superimposing the reciprocating motion along two axes at different frequencies and / or with a phase shift, the axes preferably lie in the plane of the cross-section of the container. For a trajectory that is formed by superimposing the reciprocating motion along three axes, two of the axes preferably lie in the cross-sectional plane of the container, and the third axis is at an angle to this cross-sectional plane. The lowest frequency of the complete reciprocating motion along one of the three axes forms the frequency of the sequence of trajectory segments. In general, the linear motion axes are preferably at right angles to one another.
[0016] Generally, the device is configured to drive the container along a trajectory formed by the superimposition of the reciprocating motion of at least two superimposed linear axes arranged at an angle to one another, wherein the reciprocating motion along the linear axes occurs at different frequencies and / or with a phase offset. The linear axes, along which the superimposed reciprocating motions occur at different frequencies and / or with a phase offset, form the trajectory along which the reciprocating motion of the container occurs, for which the device is configured.
[0017] By moving the container along the trajectory curve, the device is designed to accelerate the substances relative to the container so that substances contained in the container are intensively contacted with liquid or air by the acceleration against the container wall.
[0018] Because the trajectory can be adjusted or predetermined by the different frequencies and / or the phase shift of the superimposed movements along the linear axes, the device is designed for the reciprocating movement of the container along the trajectory and for the relative movement of the substances therein with respect to the container.
[0019] The trajectory, which can be adjusted or predetermined by the different frequencies and / or phase shift of the overlapping movements along at least two linear axes, accelerates the substances relative to the container. The reciprocating movement of the container drives the substances and the liquid contained therein toward the inner wall of the container.
[0020] Optionally, the container is not rotationally driven, at least during the movement along the trajectory, and more preferably is not or not fully rotatable, e.g., guided so as to be rotatable by a maximum of 30° or a maximum of 20° or 10° around its longitudinal axis. Generally, the container is preferably driven exclusively for a reciprocating movement along a trajectory, optionally additionally drivable for rotation when the container is not moved along the trajectory, in particular optionally driven exclusively for rotation with a time offset to the reciprocating movement along the trajectory. Optionally, the container is mounted so as to be freely rotatable about an axis perpendicular to the plane of the trajectory and is not rotationally driven about its longitudinal axis.
[0021] The trajectory allows the angle of incidence and reflection of the substances against the container wall to be determined. Furthermore, the device is optionally configured to move the container along the trajectory at an adjustable or predetermined acceleration and speed. Because the device is configured for an adjustable or predetermined trajectory and / or an adjustable or predetermined acceleration and / or an adjustable or predetermined speed along the trajectory of the container's reciprocating movement, the substances and liquid contained in the container are propelled relative to the container at an adjustable or predetermined maximum acceleration and / or an adjustable or predetermined speed, allowing a predetermined or continuous adaptation of the process to the substances to be treated.
[0022] In general, a trajectory can be formed by at least two superimposed individual oscillations. Preferably, a trajectory resembles the trajectory generated by superimposing reciprocating movements along at least two linear axes of motion, each at different frequencies and / or by a phase shift. A reciprocating movement along a trajectory that resembles a reciprocating movement along superimposed linear axes of motion exhibits different frequencies and / or a phase shift. Optionally, the trajectory can be a circular path or exclude circular paths.
[0023] The difference in frequencies can be, for example, at least 0.01 Hz and / or 0.01% to 900%. The phase offset of the reciprocating movements along the linear axes can be, for example, from 0.01° to 180°, preferably 1 to 179° of 360°, which corresponds to a complete reciprocating movement. 0.01 to 180° of a complete reciprocating movement of 360° is equal to 0.0028% to 50% of a complete reciprocating movement, and 1 to 179° of 360° is equal to 0.28% to 49.7% of a complete reciprocating movement. The linear movement axes are, for example, perpendicular or at another angle, e.g., 5° to 85° to one another, in particular in the plane of the cross-section of the container or perpendicular to a longitudinal axis of the container. Optionally, the trajectory curve contains trajectory segments with at least one straight section, the end of which is, for example, a vertex at which the substances are accelerated relative to the container wall.
[0024] To set different frequencies and / or a phase shift of the superimposed reciprocating movements along at least two linear axes of motion, these reciprocating movements can be coupled to one another by a gear or a guide rail and driven by a motor. A motor-driven gear that adjusts the reciprocating movement along the trajectory curve can have a fixed gear ratio between the superimposed movements along each axis or an adjustable gear ratio, e.g., a continuously or stepwise shiftable gear. Optionally, the gear can be subject to slip, e.g., a belt drive or a friction gear.
[0025] The output speed of the gear that drives the reciprocating movement of the container is preferably at least 0.5 Hz, more preferably at least 2.5 Hz, at least 5 Hz, e.g. up to 10 Hz, e.g. 4 Hz up to 40 Hz, up to 30 Hz, up to 20 Hz or up to 10 Hz. The output speed of the gear is equal to the frequency of the reciprocating movement.
[0026] Alternatively, the reciprocating motion along each of the linear motion axes can be driven by a separate motor, with the lower output speed being the frequency of the reciprocating motion and constituting the frequency of the sequence of path segments. In either embodiment, the speed of each drive motor can be controlled, fixed, or variable over the duration of the process.
[0027] The device allows the trajectory to accelerate the substances in a defined direction towards a specific location on the inner wall of the container. The geometry of the container in conjunction with the trajectory can support the washing process so that the trajectory can be adjusted depending on the shape and size of the container cross-section. Optionally, the device is designed to change the trajectory of the reciprocating movement and / or the acceleration and / or speed of the reciprocating movement during the process, e.g. in a first phase the reciprocating movement can be set along a first trajectory and with a first acceleration and speed and in a subsequent second phase the reciprocating movement can be set along a changed trajectory and / or changed acceleration and / or speed.
[0028] Another option is for the reciprocating movement to be a linear reciprocating movement in a first phase and a reciprocating movement along merging trajectories in a second phase. The trajectory can be determined, for example, by a gear that drives the movement of the container.
[0029] The device allows a predetermined or dynamically variable and directed acceleration of the substances relative to the container by adjusting the trajectory and acceleration of the reciprocating movement of the container.
[0030] In an embodiment in which the container can be driven in a controlled manner to a linear reciprocating movement in a first phase, the device is designed to move substances and optionally liquid perpendicularly against the container wall with a controllable acceleration that is significantly greater than the acceleration due to gravity and therefore essentially independent of the acceleration due to gravity, e.g. with a maximum acceleration of at least 15 m / s 2 , preferably 25 m / s 2 , preferably at least 50 m / s 2 or at least 100 m / s 2 or at least 200 m / s 2 or at least 350 m / s 2 e.g. up to 500 m / s 2 .
[0031] In general, the device can be designed to accelerate the container with a maximum acceleration of at least 15 m / s 2 , 20 m / s 2 , or at least 25 m / s 2 , e.g. at least 50 m / s 2 , preferably up to 100 m / s 2 , preferably 200 m / s2 , e.g. up to 300 m / s each 2 or 450 m / s 2 , up to 260 m / s 2 or up to 250 m / s 2 to accelerate along the trajectory curve, e.g. at a vertex of the trajectory curve.
[0032] The container is preferably designed for a back and forth movement with a maximum acceleration of at least 0.5 m / s 2 or at least 1 m / s 2 or at least 2 m / s 2 at least 3.5 m / s 2 , preferably at least 60 m / s 2 , preferably at least 100 m / s 2 , at least 150 m / s 2 , at least 160 m / s 2 , at least 200 m / s 2 , e.g. up to 300 m / s each 2 or 450 m / s 2 , up to 260 m / s 2 or up to 250 m / s 2driven along each of two axes. Generally, the container is preferably driven along one of the axes, preferably along each axis, in combination with the acceleration to an average speed of at least 0.5 m / s, preferably at least 2 m / s, more preferably at least 3.5 m / s, e.g., up to 10 m / s or up to 20 m / s or up to 6 m / s, e.g., 3 to 4 m / s. The path of movement along at least one axis, preferably along each axis, is, e.g., 0.1 cm to 24 cm.
[0033] The container can, for example, be driven to move back and forth over a distance of at least 1 mm or 2.5 mm, at least 1 cm, more preferably at least 2 cm or at least 5 cm, at least 10 cm or at least 15 cm, e.g. up to 100 cm, up to 50 cm, up to 30 cm or up to 20 cm, along each axis. More preferably, the move back and forth of the container is harmonic. The move back and forth of the container can be linear in a first phase; in general, the trajectory is non-linear and can, for example, be sinusoidal, triangular, loop-shaped, pretzel-shaped or arc-shaped, e.g. run along a so-called Lissajous figure or hypocycloid, which preferably lies in the plane or is two-dimensional, optionally three-dimensional.Preferably, the reciprocating movement is linear in a first phase and, in a second phase, is formed into a trajectory curve along at least two non-linear path segments, each of which contains at least one vertex. This is because, in general, a non-linear trajectory curve, e.g., a movement along a trajectory curve whose path segments each have at least one vertex, promotes the impact of materials perpendicularly against the inner wall of the container, as well as, optionally, a uniform and intensive rolling or sliding of the materials, at least in sections, along the optionally structured inner wall.
[0034] The back and forth movement preferably comprises the back and forth movement along merging trajectories, which comprise at least two, preferably at least three, more preferably at least four different trajectories that merge into one another in a sequence-controlled manner. Each of the movement axes along which the movements overlap to form a trajectory can be linear or arcuate, so that the non-linear movement of the container is generated from the superposition of the movements along two movement axes. The container wall is the circumferentially closed wall of the container, which extends around a longitudinal axis and between respective end-opposite cross-sections or lids attached thereto. The container has an optionally circular cross-section that extends around a longitudinal axis and is spanned by the container wall.Generally, the terminal cross-sectional openings of the container are each preferably covered by a lid, of which optionally at least one has a through opening.
[0035] In general, it is preferred that the trajectory has at least one, preferably at least two or at least three trajectory segments, each having at least one apex at which it changes its direction by at least 90°, more preferably by at least 120°, even more preferably by at least 180°. In general, it is preferred that at least one trajectory segment has an apex at which the direction of the trajectory segment changes by at least 90°, more preferably by at least 120°, even more preferably by at least 180° or at least 210°, e.g. within a maximum of 24.5%, a maximum of 24%, a maximum of 23%, a maximum of 22%, a maximum of 21%, a maximum of 20%, a maximum of 15% or a maximum of 10%, more preferably a maximum of 5% or a maximum of 3%, a maximum of 2% or a maximum of 1% of the length of a trajectory segment. This is because a apex of the trajectory leads to a strong relative acceleration of the substance against the container.The vertices and intermediate sections of a path segment are determined by the frequency difference and / or the phase position of the superimposed reciprocating movements along at least two axes. In general, the device can be configured to change the frequency difference and / or the phase position during the reciprocating movement.
[0036] The control of the drive of the container is optionally controlled depending on the signal from a sensor, preferably an acoustic sensor, which records vibrations, in particular noises of the container during the back and forth movement, in particular during the first and / or during the second phase. The acoustic sensor can, for example, be attached to the outer surface of the container or fixed at a distance from the container in a position past which the back and forth movement of the container passes. Preferably, the acoustic sensor is fixed at a short distance, e.g. 0.5 to 5 cm, from the apex of the back and forth movement, e.g. fixed to a frame relative to which the container is moved along the trajectory. The acoustic sensor can be a vibration sensor, e.g. a microphone.In this embodiment, the control of the reciprocating movement can be set up to allow the reciprocating movement to run at a changed speed and / or with a changed phase offset and / or to control from a linear movement to a trajectory curve, in particular to control from a first phase to a second phase of the reciprocating movement, when the signal emitted by the acoustic sensor changes by a predetermined deviation within a predetermined time of the reciprocating movement, and / or when a predetermined signal emitted by the acoustic sensor is reached.
[0037] The sensor can also be an optical sensor attached to the container, e.g. a turbidity sensor.
[0038] Optionally, a device for generating electrical voltage is attached to the container, in particular a device with a magnet and a coil arranged so as to be movable relative to the magnet, which are configured to generate electrical voltage when moved relative to one another. This device is preferably connected by means of an electrical line to a transmitter attached to the container in order to supply the transmitter with electrical voltage. The transmitter is preferably connected by means of a data line to at least one of the sensors in order to receive sensor signals. The transmitter is configured, for example, to transmit received sensor signals. Furthermore, the sensor can be connected to the device for generating electrical voltage by means of an electrical line.In this embodiment, the device is configured so that a sensor and a transmitter attached to the container can be energized by the device for generating electrical voltage as soon as the container is moved along the trajectory curve. Accordingly, the device can be designed without an electrical cable extending between a frame, relative to which the container is moved, and the container.
[0039] In general, the path of movement is along at least one axis, preferably along each axis, e.g. 5 cm to 24 cm.
[0040] The inner wall and the outer wall can be made independently of each other, different or the same, from metal, preferably stainless steel, plastic or ceramic.
[0041] Optionally, a line for supplying air, preferably at a temperature of 30 to 90 °C or up to 60 °C, is connected to the container to dry substances in the container while the container is moved along merging trajectories or while the container is moved back and forth linearly. An outlet line, which can be, for example, the line connected to the space between the inner and outer walls, is preferably connected to the container to remove moist air from the container.
[0042] The through holes in the inner wall can be round holes or elongated holes that extend parallel or perpendicular to the cross-section of the interior, or that extend at an angle of >0° to <90° to the cross-section of the interior. Optionally, additionally or alternatively, the through holes can extend along the radial lines or at an angle of 10 to 45° to radial lines emanating from the longitudinal axis of the cross-section spanned by the inner wall. Optionally, the through holes have a constant cross-section or a cross-section that widens with increasing distance from the longitudinal axis. Generally speaking, the through holes preferably have a chamfer, preferably arcuate, in order to avoid sharp edges adjacent to the cross-section. In a simple embodiment, the inner wall can be a grid whose webs form the through holes between them.
[0043] The inner wall can be connected to the outer wall by supports that extend across the space between the inner and outer walls. The inner wall can be connected to the outer wall by the inner wall resting against supports that extend across the distance between the inner and outer walls. Supports between the inner and outer walls can be formed integrally with the outer wall or the inner wall or can be connected to one or both of them, e.g. soldered, welded or glued. Alternatively, supports can only be arranged in a form-fitting manner between the inner and outer walls, e.g. as at least one separate element. The supports can be designed as webs that extend parallel to the cross-section of the container interior, e.g. annular or angular like the container interior, or as webs that are at an angle to the cross-section of the container interior, e.g.spirally, preferably as webs which extend perpendicular to the cross-section of the container interior, so that channels are formed between them which open at a distance in front of at least one, preferably both end cross-sectional areas of the space between the inner and outer walls. Furthermore, the supports can be formed by a grid in which, for the passage of liquid and air, a proportion of the webs has a lower height than the distance between the inner and outer walls. Generally, supports, in particular designed as webs, form the dead volume between them through which liquid, optionally air, can be supplied and / or discharged separately from the laundry, e.g. during vacuuming or drying, in particular by means of lines which are connected to the space between the inner and outer walls.
[0044] The method carried out using the device has the advantage that when the container moves along merging trajectories, especially at high acceleration maxima of substances relative to the container or the inner wall, the substances contained therein are intensively contacted with the liquid, e.g. are milled, and can roll off the inner wall, so that the substances preferentially rub against each other and rub less against the inner wall of the container.
[0045] In addition, fine air bubbles are created which accelerate the cleaning process when the fibers are rinsed.
[0046] The invention will now be described in more detail by way of example with reference to the figures which are shown schematically in
[0047] - Fig. 1 shows an exemplary container and Fig. 2 shows the container of Fig. 1 in section AA.
[0048] In the figures, the same reference numbers denote functionally identical elements.
[0049] Fig. 1 shows a container 1 which, as is generally preferred, has a circular cross-section, with a first access opening 4 arranged along the longitudinal axis 2 on a first lid 3 and a second access opening 6 arranged along the longitudinal axis 2 on the opposite second lid 5. Lines can be connected to the access openings 4, 6, e.g. for supply air and exhaust air during drying. The first lid 3 and the second lid 5 each cover an end cross-section of the container 1. These lids 3, 5 run in a funnel shape, alternatively in the plane of the container cross-section, from the container 1 to one of the access openings 4, 6. Alternatively, the container 1 can have only one access opening 4, 6, which is arranged in one of the lids 3, 5, so that the filling and emptying of the container 1 can take place through only one common access opening 4, 6.Preferably, one of the lids 3, 5 is detachably attached to the container 1 in order to be able to fill textiles or leather into the container and remove them therefrom.
[0050] A sensor 30, attached to the container 1, is connected via an electrical line 31 to a voltage generating device 32, which is attached to the container 1 and has a magnet movable relative to a coil. A transmitter 33 is connected to the sensor 30 via a data line 34 and to the voltage generating device 32 via an electrical line 35.
[0051] The longitudinal section through the container 1 shown in Fig. 2 shows the through holes 10 in the inner wall 11. The inner wall 11 is enclosed by the outer wall 12. The outer wall 12 is spaced from the inner wall 11 by the supports 13. The connection 14 opens into the space between the inner wall 11 and the outer wall 12, e.g., for introducing liquid or for removing liquid or air.
[0052] Example: Treating fabrics
[0053] As an example of materials, 5 kg of cotton fabric were placed in a container with a cylindrical inner cross-section of 50 cm in diameter and a longitudinal extension of 80 cm. The inner wall was made of stainless steel sheet and featured chamfered holes of 2 mm in diameter, spaced 2 cm apart. The outer wall was a stainless steel cylinder spaced 3 mm apart, with supports formed by plastic webs inserted into the space approximately parallel to the longitudinal axis of the container.
[0054] The end cross-sectional areas were closed with clamped lids, one of which had a connected hose for supplying water and detergent. A nozzle with a hose was attached to the outer wall, which connected to the space between the inner and outer walls.
[0055] Two liters of water containing detergent were poured into the container through the hose connected to the lid. The container was then moved back and forth for 10 to 30 minutes along trajectories, each 30 cm long. The trajectories were generated by moving back and forth along a first linear axis at 4 Hz and along a second linear axis, offset by 90° to the first axis, at 5 Hz. In another experiment, dye was distributed in the water instead of detergent to dye the fabric. Before filling the container with water, the container was vacuumed using a vacuum pump connected to the hose.
[0056] The back and forth movement was then stopped and liquid was drawn through the hose; optionally, the container was moved along a circular path so that the laundry rolled along the inner wall and liquid was pressed out of the fabric into the space between.
[0057] Then, clear water was filled into the container twice and, each time while moving the container in a circular path, water was drawn off through the hose to rinse the fabric in two steps.
