Definitions

  • the present invention relates to a washing machine that are used for the wet, dry, physical or chemical treatments which is generally called “chemical washing” and “stone washing” that applied to give textile garments a worn appearance, comprising a shaft positioned horizontally or having an angle with the horizontal axis, a bearing system, a perforated drum, an outer drum tank outside the inner drum wherein the water coming out of the drum is collected, movable parts placed inside or outside the drum in order to aid the working of the machine and/or increase the performance of the machine and/or provide economy of resources used by the washing machine such as water, energy, chemicals and time, mechanical motion systems placed inside or outside the drum that are connected to said movable parts for moving said movable parts in a controlled manner.
  • the appliances described by this invention are generally referred to as "washing machines” because they can be used for a variety of purposes and can have different capacities. Appliances of this kind having a capacity between 100 to 500 kg are used in industry. These appliances are most widely used in washing and stone washing. Even though they are mostly used for wet treatments, they can also be used for dry treatments in special applications such as abrasion. There are 3-4 lifter ribs on the perforated cylindrical surface of the drum to ensure that the material moves along with the rotation of the drum. The physical effect is realized by this movement caused by the rotation of the drum.
  • One of the treatments requiring the physical effect is the "stone washing" treatment that was first used on denim jeans in the 1970s and became more widespread in the 1980s to impart an aged, used and worn appearance to textiles.
  • Pumice stone is a natural volcanic stone and is light in addition to being abrasive so it is advantageous in abrasion treatments because it can float in water. However, it gets crumbled in the treatment water and loses its floating ability and causes serious pollution in the environment starting with the waste water system.
  • Some of the problems caused by the utilization of pumice stone are as follows: transportation from volcanic mines where they are produced to areas where they are used, storage, environmental issues such as transportation and dusting in the production areas, emptying the machine after abrasion treatment to clear textile of pumice stone, clearing textile of pumice stone, reloading and rewashing of textile to clear away pumice dust and transport of pumice waste to safe waste areas where it won't cause environmental pollution.
  • different materials were tested and different methods were evaluated for abrasion applications. All mechanical abrasive materials cause environmental pollution. Bleach, corroding and dye stripping chemicals are used along with mechanical abrasive materials or by themselves during washing.
  • a natural material is also commonly used by itself or along with stones during washing. As it is a natural material, it is accepted to be the least harmful chemical used in denim washing. Even though different materials, methods, techniques and chemicals have been used, very few changes have occurred in the past 30-40 years in terms of industrial type stone washing machines having perforated cylindrical drums. During the abrasion treatment, mechanical abrasive materials wear down areas they come in contact with such as the drum and the ribs and the chemicals used cause chemical corrosion. In order for the drum to be resistant to chemical corrosion, the inner surface of the drum is covered by stainless steel; however, no method has been able to provide a satisfactory solution to this problem.
  • the textile is both abased and works as an abrasion agent.
  • the abrasion effect is only realized when the textiles that come in contact with the abrasive drum surface. If a drum having a diameter of 1500 mm and a depth of 1000 mm is used for abrasion 50 pairs of pants, and each pair of pants is assumed to have a surface area of 1 m 2 ; while the abrasion surface using pumice stone is 50 m 2 , the drum area is only 3 m 2 .
  • grindstones in the shape of rollers rotating at 200-500 rpm would be able to increase the speed of abrasion imparted onto the textiles by hundreds of times.
  • the textile will move across the abrasive movable parts during the rotation of the drum and therefore the desired abrasion result will be achieved hundreds of times faster.
  • Parts that are movable in ways other than rotation will create a dynamic movement that will increase the physical effect obtained only by the rotation of the drum by tens and hundreds of times and decrease treatment time and as a result increase efficiency and decrease costs by providing savings in time, energy, manpower and resources and provide a more environmentally friendly process.
  • Movable parts placed within the drum will increase the physical effect provided by laundry washing appliances and therefore increase the quality of the treatment while reducing treatment time and chemical consumption.
  • One of these effects is rubbing the laundry against each other.
  • Fraser US2002029594, 2002-02-07
  • This system had some issues due to its mechanical structure and coupled with its costs, it had limited application. Its mechanical structure makes it even more difficult to adapt to industrial size appliances than to household appliances.
  • Movable parts rotating or vibrating on the drum surface will increase the rubbing effect and the quality of washing.
  • a machine having rotating brushes will be able to clean floor mats and other hard material much faster.
  • rollers having plastic protrusions will create rubbing effect on the laundry by rotating slowly.
  • Movable parts can be moved using a wheel system placed outside of the drum. Movable parts placed outside of the drum can also eliminate the imbalance caused by the uneven distribution of the laundry within the drum during the spin cycle and the resulting vibration of the machine.
  • front-loaded horizontal washing machines providing a spin cycle have a balance system that can be summed up by two principles. The most commonly used balance system utilizes ball that are free to move within a circular tube or channel placed at the rotation axis of the drum, wherein these marbles can be displaced to provide a counterweight to the imbalance. Many application options are suggested for this system and some of these have been applied to the front, the rear or the front and the rear of the drum.
  • the system is based on the principle of the marbles being displaced by the eccentric motion of the drum in a manner to provide a counterweight to a possible imbalance in the drum.
  • Another balancing system known and used in the art is addition of external weights to provide a counterweight.
  • Obtaining a counterweight by adding a weight was first proposed by Kahn in 1945 (US2534267, 1950-12-19) and then developed further in 1946 and 1948 (US2534268 and US2534269). This technique was further developed by Starr in 1958 (US3117926, 1964-01-14 and US3214946, 1965-11-02) and by Pellerin in 1992 (US5250660, 1994-01-25).
  • Simsek developed a water-balance system that presents an improvement over systems providing balance by adding water to three carrier ribs in the drum by adding water to water compartments placed in the front and the rear of the drum (US6510715, 2003-01-28).
  • the proposed system provides a much more sensitive balance system because the imbalance is balanced from the front and the rear. From 2000 onwards, this system has been successfully utilized in high capacity industrial washing machines having spin cycles.
  • the water-based balance system proposed by Simsek is very successful in terms of providing balance, addition of water is required constantly because it is not possible to remove the water added during the spin cycle. Balance water is transferred to the balance cells by the opening and closing of the valves so the balancing process takes time. Another problem is water consumption.

For example depicting small scale machines for household use, the drum has a diameter of approximately 575 mm and a depth of approximately 4500 mm, having a gross volume of 110 L and net volume of 100 L. the difference between gross and net volumes is a feature of the invention and will be explained below.

  • Movable parts inside the drum creates physical effects in addition to those created by the rotation of the drum and are used to increase the physical and chemical performance inside the drum. Said movable parts are placed inside the drum, which increase the desired physical effects on the materials placed within for treatments such as washing, dyeing, abrasion, polishing and brushing.

This is good for washing conditions, but if same machine is also use for washing without abrasive conditions running of the rollers must be stopped. Also same conditions need during extraction. High spinning speed during extraction is not good for mechanical wheel system. It is also not good if textile still have contact with abrasive roller surface during extraction. So we have to stop movements in the drum. This is possible to move wheel path pieces (405) away from the wheels (404).

Even if the brush rollers have indented surfaces, the indentations of the fixed brushes will be placed in-between the indentations of the brush rollers to prevent the materials from getting tangled.
  • Brush rollers (203) will be especially useful for washing heavily stained and dirty materials such as work uniforms and table cloths. Using brushes having a special surface structure along with chemicals will provide faster and more effective cleaning.
  • rollers (201) Another feature of rollers (201) is that said rollers can be mounted to and dismounted from roller bearings (205). Therefore, the changes required by different types of treatments can be realized quickly.
  • eccentric rollers (204) When the rotation axis of rollers (201) is offset from the central axis of the cylinder, the rotation of said roller (201) will be eccentric. Rotation of eccentric rollers (204) will provide a beating effect to the materials in addition to the friction effect. The same effect may be obtained by elliptical rollers as well. In conclusion, when eccentric rollers (204) whose surfaces rotate eccentrically are used in washing machines, they will provide a rubbing effect on the laundry.
  • a stone washing machine is explained below. Stone washing treatments constitute a significant portion of treatments performed in industrial washing machines. And industrial stone washing machines are the most widely sold type of industrial washing machines. Generally pumice stone is used as the abrasive material in stone-washing, which is known to be the most problematic type of washing. The reasons for that can be summarized as: the problems associated with obtaining, transporting, storing, loading and disposal of pumice stone residuals and environmental issues caused by waste water containing pumice stone sand; and health issues caused by dust and debris buildup in the facility. The present invention eliminates these downsides of stone-washing.
  • pumice stones in size that will pass through the drum holes and the pumice sand will be pumped through the same circulation system and pumped back to the drum by means of the pump.
  • the pumice particles also wear the pump propeller while passing through the pump.
  • pumice particles tend to accumulate in areas where water flow is weak and tend to over time.
  • cyclone separation and circulation system (500) that explained later have to be applied. So all that abrasive particles separate before pump and inject circulation water after pump.
  • abrasive materials also abrade the surfaces they come in contact with and in time render some of the parts unusable.
  • Abrasive materials used in the drum will render the drum sheet unusable in 2 to 3 years.
  • the present invention eliminates this problem. If the surfaces of the movable parts placed in the drum contain the required abrasiveness, it will be possible impart the desired abrasion effect to the textiles being treated.
  • a stone washing machine having additional abrasive particles according to the present invention is explained below. It is possible to use different types of abrasive materials in stone washings. When abrasive particles comprised of different sizes such as granules, pieces, particles and dust are rotated in the drum along with textiles, they will wear down the surface of the textiles and create the desired abrasion effect. However, as with pumice stone, these abrasive materials cause cleaning and environmental issues after being discharged from the machine along with water.
  • Figure 3 demonstrates a schematic view of a stone-washing machine wherein abrasive particles (501) enter the drum along with water and mix in-between the textiles and function as abrasive agent while a fraction of abrasive particles (501) is drained from the drum (104).
  • Both the drum and water tub (101) should be designed to prevent long-lasting and durable abrasive particles (501) from settling at certain spots. Long-lasting and durable abrasive particles (501) tend to settle and collect at spots where water flow is slow. When sedimentation starts at a certain spot, the amount of settled material increases rapidly and hardens over time to form a structure that is very hard to clean.
  • Abrasive particles (501) in sizes of granules, pieces, particles or dust that can be carried by water in the circulation system are transferred to water tub (101) via the drum holes along with water. Water needs to be cleared of long-lasting and durable abrasive particles (501) before it is pumped back into the drum from tub (101). It is possible for long-lasting and durable abrasive particles (501) to be pumped back into the drum along with water; however, this has two drawbacks. When long-lasting and durable abrasive particles (501) pass through the pump, they will quickly wear down the pump propellers and therefore it will be inevitable that pump problems arise frequently. Additionally, the abrasive quality of long-lasting and durable abrasive particles (501) will decrease due to their contact with pump propellers.
  • One of the most practical among the conventional methods of separating particles of a size float by a fluid from said fluid is a cyclone system (500).
  • One or multiple abrasive particle separation cyclones (502) placed in parallel will be suitable for continuous and low-maintenance separation.
  • Water draining from water collection tank (501) will enter said abrasive particle separation system (502) before being pumped back into the drum.
  • Pump (112) draws water out of cyclone water outlet (503) and helps clear the water of abrasive particles in the cyclone.
  • Long-lasting and durable abrasive particles (501) exit the cyclone from cyclone particle outlet (504) under the cyclone and water exits from cyclone water outlet (503) connected to pump inlet largely free of solid particles.
  • Long-lasting and durable abrasive particles (501) separated from water in the cyclone are collected in particle collection tank (506) to be reused.
  • a particle injection-feed screw (507) system placed under particle collection tank (506) will enter circulation line (113) at the pump (112) outlet from particle inlet to circulation line (508) to mix the particles into water and injects abrasive particles (501) into the pipeline at the pump (112) outlet with the rotation of the feed screw driven by screw motor (505). In this way, abrasive particles (501) are returned to the drum along with water.
  • abrasive particles (501) are collected in particle collection tank (506) to be used in the next stone-washing treatment.
  • particle collection tank (506) After injection of abrasive particles (501) into drum (104) is over, the water circulation is continued to collect the particles remaining in the drum and ensuring that the drum and the materials undergoing treatment are completely cleared of abrasive materials. While abrasive particles (501) are being cleared, the required chemical washing will also be performed. Therefore, the time needed for the drum and textiles to be cleared of particles will not be wasted.
  • a stone-washing machine comprising a drum covered with abrasive sheets (264) according to the present invention is explained below.
  • a drum wherein stone washing operation is performed with abrasive particles (501) may have inner surfaces having abrasive character.
  • the inner surfaces of the drum are covered with abrasive materials (264).
  • the drum will wear down the material that is being stone-washed therein by its rotation.
  • abrasive sheets There are two advantages to covering the inner surfaces of the drum with abrasive sheets (264). Abrasive materials are produced to be resistant to abrasion due their function and production methods. While abrasion treatment with abrasive particles (501) is ongoing within the drum, said abrasive particles (501) together with the materials undergoing treatment will come in contact with drum interior (104-n) and wear down the surface of said drum interior (104-n). Whereas, if the inner surfaces of the drum are already covered with abrasive material (264), the material constituting the drum sheet will not be worn down and it will take a long time for the abrasive covering to be worn down and said covering can be replaced when needed.
  • abrasive sheets (264) placed on drum interior (104-n) will also provide abrasive effect to the textile coming in contact with said surfaces and therefore will shorten the time needed for the treatment operation.
  • covering drum interior (104-n) surfaces with abrasive materials will be an advantageous embodiment.
  • Figure 6 shows covering of the drum surface in a reversible manner, using different types of covering materials. Said embodiment may be applied along with other stone-washing features of the invention.
  • a drum having abrasive movable parts mounted within may also be covered with abrasive material as discussed above. All embodiments having abrasive features disclosed herein may be used together, simultaneously.
  • Movable parts inside drum (200) having abrasive character make the systems described by the present invention most suitable for stone-washing applications.
  • the desired abrasion effect on the textile can be achieved even if there are no additional abrasive materials inside the drum by covering the surface of movable abrasive parts (260) mounted on drum interior (104-n) with abrasive materials, mechanically or chemically treating the material constituting the surface of said movable abrasive parts (260) to impart abrasive character or choosing an abrasive material such as grindstone as surface material for said movable abrasive parts (260).
  • Mechanical abraders added to drum (104) along with textiles will provide wearing down of textiles by the friction created by the textiles rubbing against each other with the rotation of the drum. In the case where movable parts are abrasive, abrasion by friction will take place between the textiles and said movable parts inside the drum.
  • Rollers (201) having grindstone pieces (207) mounted thereon according to the present invention are explained below.
  • One of the most important embodiments of the invention is having movable abrasive parts (260) mounted on drum interior (104- n) be in the form of abrasive rollers (202).
  • stone-washing of denim jeans is done in multiple steps.
  • the first step is stone-washing with abrasive materials to impart a base design onto the jeans.
  • the pants are dry-treated to impart the desired shapes thereon to.
  • One of these treatments is an application where fold marks are created on desired sections of the pants.
  • This treatment application may entail creation of lines or marks on the jeans using laser technology or small grindstones rotating at high speeds. Abrasive grindstone rollers (206) rotating inside the drum will have the same effect on the jeans.
  • FIG. 7-10, 13-18 and 20 show different examples of abrasive rollers (202) mounted on drums (104) of industrial stone washing machines (153). It is preferable for abrasive rollers (202) to have a grindstone surface; however, it is not required. It is also possible to use abrasive rollers (202) produced by methods to obtain abrasive materials known in the art, such as covering by an abrasive material other than grindstone and shaping metal to have an abrasive surface.
  • rollers (201) may be produced from solid grindstone (206). Cylindrical abrasive grindstone rollers (206) having support materials added during the production stage to make them more durable may be mounted in the drum. Rollers (201) do not have to be produced from solid grindstone. Rollers (201) may comprise cylindrical (210) or spherical/buckled (211) grindstone pieces (207) mounted on a mechanical structure.
  • Spherical/buckled grindstones (211) may be preferred in order to prevent formation of different levels of abrasion at the folds of the textiles contacting the rollers and to impart different designs to the textile. Spherical/buckled grindstones (211) may be preferred even though treatment time increases because abrasion in desired shapes can be obtained.
  • Figure 12-14 shows cylindrical abrasive grindstone rollers (206), rollers comprising cylindrical grindstone pieces (210), rollers comprising spherical/buckled grindstone pieces (211) and abrasive rollers (202) covered by protrusions such as brushes (203) for use as abrasion agent.
  • Figure 12 also exemplifies different abrasive pieces that can be used on the rollers.
  • Mounting cylindrical abrasive rollers (202) that are bed housing from two ends by roller bearings (205) and that can rotate around its axis into the drums of stonewashing machines will speed up the stone-washing process and provide many advantages to the textile industry.
  • Factors such as the number of rollers (201) inside the drum, the degree of abrasiveness of the abrasive material on the surface of the rollers and the surface speed depend on the wheel pulley and roller diameters provide a wide variety of options that allow for customization of the treatment based on the type of material being treated, the stone-washing effect desired and the target quality of the end product.
  • An embodiment of an industrial stone washing machine comprising abrasive grindstone roller (206), abrasive and felting brush rollers (203), fixed grindstone pieces (216) mounted on drum interior (104-n) and a circulation system with abrasive particles (500) along with smooth or indented abrasive sheets (264) covering the drum surface will provide the user with many options with which to customize treatment formulas compared to treatments performed using pumice stone only.
  • An exemplary embodiment of a stone washing machine of the invention as shown in detail in Figure 14 comprises abrasive rollers (202) comprising cornered grindstone carriers (212) serving as a shaft between roller frontal bearing (205-f) and roller rear bearing (205-r) having abrasive grindstone rollers (206) of measurement and shape suitable for said grindstone carriers (212) mounted thereon to or covered by grindstone pieces mounted side by side to cover the surface of said shaft.
  • the reason why grindstone carriers (212) carrying and realizing the rotation of the grindstones have a cornered structure is to facilitate the rotation of the grindstones.
  • Quadrangular grindstone carriers (212-4) and hexagonal grindstone carriers are preferable due their suitability for grindstone production methods and their ability to function as a wedge. However, it should be understood that any known techniques for facilitating the rotation of grindstones along with said carriers may be utilized.
  • the grindstone mounted onto said carriers through the central hole therein is a single piece, it is preferable that they be in multiple parts. As the different sections of grindstones covering the drum interior (104-n) surface from rear to front will be worn down at different rates, the whole part will need to be replaced based on the most worn down section. However, if pieces of grindstone are used, it is possible to only change the most worn down grindstones. As abrasive grindstone rollers (206) are made of long single pieces, they are not durable against bending and have high risk of breaking which requires them to be produced using special techniques. Additionally, a single piece of grindstone will be harder to mount that multiple grindstone pieces (207). For these and similar reasons, it is preferable to use multiple grindstone pieces (207) to form abrasive grindstone rollers (206).
  • Grindstone carriers (212) may be quadrangular grindstone carriers (212-4) as shown in Figures 12 and 14 or hexagonal grindstone carriers as well as any polygonal shape acting as a wedge for the holes in the grindstones.
  • Movable parts in the form of rollers (201) are reversibly mounted on roller bearings (205) located at drum rear section (110) on the drum shaft (103) side and at drum frontal section (109) on the cover side in the drum, parallel to the drum axis where they can rotate around the axis of said bearings. It is advantageous for the rollers to be mounted and dismounted by a practical mechanism. Therefore, it is possible to use any mechanism known in the art for practically mounting and dismounting rollers from two roller bearings (205).
  • Roller frontal bearing shafts (213) providing the connection between roller bearings (205) located at drum rear section (110) drum frontal section (109) can be mounted into roller bearings (205) by the force extended by roller frontal bearing pressure springs (215) in roller frontal bearing shaft housing (214) and rotatable lock abrasive grindstone rollers (206) between the bearings.
  • Grindstone pieces on roller (207) may be cylindrical, spherical, buckled, conical, eccentric or indented.
  • Fixed grindstone pieces (216) located inside the drum according to the present invention are explained below. Abrasive character can be imparted to the inner surface of the drum by methods other than covering said drum with abrasive sheets (264). One such method is covering the drum with fixed grindstone pieces (216). As shown in Figures 7-10 and 13 covering the area of the drum in-between abrasive grindstone rollers (206) with fixed grindstone pieces (216) instead of abrasive sheets (264) as shown in Figures 6 will have different advantages. Fixed grindstone pieces (216) having an indented structure possess a larger abrasive surface area to come in contact with the textile than abrasive sheets (264). Also, it is possible to only change the parts that have been too worn down to function.
  • Stone washing treatment in the drum may be performed dry or generally with the addition of water and chemicals.
  • Abrasive rollers (202) may be placed on the cylindrical surface of the drum side by side in the manner that no space is left between them. This way the whole area of cylindrical drum sheet (106) will be movable and abrasive and it will be possible to decrease the time needed for the stone washing treatment by adjusting the speed of the rollers.
  • abrasive rollers (202) In order for abrasive rollers (202) to wear down the surface of the material, there needs to be friction between said material and rollers. If abrasive rollers (202) placed side by side are all rotated in the same direction, the materials sitting thereon would be carried by the rollers in the direction of rotation. In this case, wearing down of materials decreases significantly.

  • Fixed grindstone pieces (216) placed between abrasive rollers (202) may be of different sizes depending on the space between said abrasive rollers (202). When abrasive rollers are placed close together, only a fixed grindstone rod (217) can fit between them. But when abrasive rollers are placed farther apart, larger fixed grindstone pieces (216) can fit there between. Like the grindstones on the abrasive rollers, fixed grindstone pieces (216) are mounted to be replaceable. If they are large in size, it would be advantageous for them to have coarse fixed grindstone (219) structure.

  • Placing water channels (220) in large fixed grindstone pieces (216) so that excess water can be discharged during impact of textile to decrease the buffer effect of water will provide faster and stronger contact between the textile and the abrasive surface and therefore increases the wearing down effect.
