Description

"DYEING TOOL" BACKGROUND OF THE INVENTION 1. FIELD OF THE INVENTION This invention relates to an apparatus for dyeing, for dyeing a narrow fabric, such as a closure tape for a slide fastener, a detachable hook and loop fastener, etc. at a low bath ratio or low liquid ratio. 2. DESCRIPTION OF THE PREVIOUS TECHNIQUE The machine for dyeing for a narrow ribbon which as disclosed in the Japanese Patent Publication Number 6-63,170, for example, implements the dye by laterally suspending a rotary arrow in the dyebath inside a pressure vessel, winding the narrow ribbon transversely in the rotary arrow and rotating the narrow ribbon wound in a dye liquid of the dyeing machine of a low bath ratio that as disclosed in the Patent Application Japanese published KOKAI (Early Publication) Number 56-112,555, for example, made the dyeing of a particular article by laterally suspending a perforated tube in a dyeing container, winding the article in the perforated tube, placing the blades of the hydraulic wheel one each on the opposite end portions of the tube perforated, allowing the dyeing vessel during rotation to pick up the dye liquid from the bottom of the dyeing vessel and transfer it to the perforated tube and causing the dye liquid in the perforated tube to discharge outward through the holes formed in the perforated tube due to the centrifugal force generated by the rotation, thus dyeing the rolled article in the perforated tube, have already been known up to now. The first dyeing machine is capable of dyeing the narrow ribbon only unevenly or inducing the narrow ribbon to become entangled because it requires the narrow ribbon to be wound transversely on the rotary shaft in preparation for dyeing. The last dyeing machine due to its inability to vary the amount of the coloring liquid in proportion to the quantity of the item to be dyed, has a tendency to consume the dye liquid and the heating energy excessively involve the problem of high production cost.

SUMMARY OF THE INVENTION An object of the present invention, therefore, is to provide an apparatus for dyeing that uniformly dyes an article such as a narrow fabric or a low bath ratio without involving problems such as uneven fabric dyeing and entanglement of fabric. the fabric, while using the coloring liquid in an amount in proportion to the amount of the fabric that is being dyed. To achieve this object, the present invention provides an apparatus for dyeing comprising a dyeing vessel adapted to contain a dye liquid therein, a rotary arrow rotatably positioned, laterally suspended in the dyeing vessel, a propeller adapted to flow the dye. dye liquid in a direction parallel to the rotary arrow, and a reel to allow an article to be dyed to be wound therein, the propeller and the reel being fixed to the rotary arrow. The dyeing of the article wound on the reel is effected by causing the coloring liquid to pass through the article from the lateral end part thereof by means of the rotation of the propeller. Due to the construction described above, it is possible to dye the article at a low bath ratio by a simple structure and not using means such as a circulation pump. Particularly in the dyeing of the narrow fabric whose rolled layer has a thickness greater than the width thereof, the dyeing apparatus in the present invention is an advantage for effecting the dyeing uniformly and quickly because the coloring liquid is made passing through the permeate through the funnel layer of the narrow fabric having a smaller thickness from the lateral terminal part thereof. In a preferred embodiment of the present invention, the dyeing apparatus comprises at least one reel and at least two propellers. The thrusters are positioned on both sides of the spool as fixed to the rotary shaft, and the rotary shaft is adapted to rotate reversibly during the course of dyeing. By periodically inverting the rotation of the rotary arrow to which the reel having the article to be dyed rolled therein and the propellers are mounted while the dyeing is in process, the direction of the flow of the coloring liquid can be changed and the liquid coloring by it can therefore be made to pass through the article from the opposite lateral end portions thereof by means of permeation. In addition, the periodic change of the direction of rotation of the rotary arrow allows the article to be quickly and uniformly dyed because it improves the permeation of the coloring liquid towards the article, causing the article wound on the reel to be tightened by rotation normal and loosen by reverse rotation. In another preferred embodiment of the present invention, the propeller and the spool are provided with the internal cylindrical parts for attaching to the rotary shaft, and the internal cylindrical parts are provided on the peripheral portions thereof with openings adapted to interconnect in order to form flow paths for the circulation of the coloring liquid. By providing the openings around the internal cylindrical parts of the precursor and the spool and thus forming the return paths for the circulation of the coloring liquid as described above, it becomes possible to standardize the circulation of the coloring liquid and effect the dyeing needed quickly and evenly. It is also permissible for the propeller and the spool to be replaceable on the rotary shaft. This arrangement allows the use of propellers and reels having the sizes and opening in the winding positions varied in proportion to the amount of the article to be dyed and allows a reduction to the cost of production. Suitably, the protective members which are permeable to the coloring liquid and capable of preventing the rolled narrow web from being laterally crushed, can each be placed on the opposite end pieces of the spool attached to the rotary shaft. They allow a forceful addition of the coloring liquid jet caused by the propellant and the intensity of the passage of the coloring liquid towards the article being dyed and, therefore, allows the dyeing to be carried out uniformly and quickly.

DETAILED DESCRIPTION OF THE PREFERRED MODALITIES Now, the present invention will be described below with reference to the modalities thereof illustrated in the drawings. With reference to Figure 1 and Figure 2 illustrating the first embodiment of the present invention, the dyeing apparatus of this embodiment comprises a container 1 for dyeing, a rotary arrow 3 rotatably placed in the container 1 so that it extends laterally therein, a pair of propellers or screws 4a and 4b, a pair of protective members 5a and 5b and a spool 6 removably attached to the rotating shaft 3, a feeding line 70 and a discharge line 71 for a coloring liquid and a heating portion 74 fixed separately to the container 1 for dyeing. The container 1 for dyeing takes the form of a hollow cylinder formed of a cylindrical wall 11 and a side wall 12 formed integrally at one end thereof. A closure or cap 13 is fixed to the other end of the container 1 for dyeing in order to open and close freely. The thrusters 4a and 4b, the protective members 5a and 5b and the carretre 6 to be attached to the rotary arrow 3 which is suspended laterally in the center of the interior of the container 1, therefore, are allowed to be inserted around and they are extracted from the rotating arrow 3 through this closure 13. The closure 13 has a sunken part 14 formed in the central part of the inner surface thereof in order to fit around and hold in position the free end part of the arrow 3 rotationally suspended laterally within the container 1. The lower part of the container 1 forms a chamber 2 for dyeing to preserve or preserve the coloring liquid. Even though the container 1 is provided with a sealing mechanism as is usual, this is omitted from the illustration. To the cylindrical wall 11 of the container 1 defining the chamber 2 for dyeing, the dye liquid feed line 70 and the dye liquid discharge line 71 are connected as shown in Figure 2.

By properly manipulating the valves 72 and 73 provided in these pipes, the coloring liquid is fed into the chamber 2 for dyeing or discharging therefrom. The container 1 is provided on one side of the bottom of the cylindrical wall 11 thereof with the heating portion 74 for heating the coloring liquid. A supply pipe 75 for the heating means serves for the purpose of feeding a heating means, such as steam, to the heating part 74. The rotary arrow 3 is rotatably attached to the side wall 12 so as to be positioned along the line of the central axis of the container 1 for dyeing. It forms in a terminal thereof a free end adapted to allow the replacement of the thrusters 4a and 4b, the protective members 5a and 5b and the spool 6. The leading terminal of this free end is adjusted in and supported by the sunken part 14 of the closing 13. The other terminal of the rotary arrow 3 protrudes laterlalente from the container 1 for dyeing. An impeller arrow 8 of a motor 7 is connected to the terminal part through the middle of a coupling 9 to impart a reversible rotation to the rotary arrow 3. On one side of the periphery of the arrow 3 rotary, a groove 31 is formed parallel to the axis. The shoulders 41, 51 and 61, which as will be specifically described below, rise from the internal surfaces of the internal cylindrical parts 40, 50 and 60, respectively of the thrusters 4a and 4b, the protective members 5a and 5b of the The reel 6 is sequentially adjusted within the slot 31. A threaded portion 32 is formed in the front terminal of the free end of the rotary arrow 3. A stop member or nut 33 is fastened to the threaded portion 32 of the rotary arrow 3 to fix the thrusters 4a and 4b, the protective members 5a and 5b and the spool 6 that have been fixed to the rotary arrow 3. Figure 2 is a perspective view showing the sequence of the fixation of the propellers 4a and 4b, the protective members 5a and 5b and the spool 6 on the rotary arrow 3. The pair of protective members 5a and 5b and the pair of thrusters 4a and 4b are separated through the spool 6 as the center are placed in sequence in the order mentioned, on opposite sides of the spool 6. The thrusters 4a and 4b are provided in the central parts thereof with the internal cylindrical parts or the cylindrical adjustment parts. The cylindrical parts 40 are provided on the internal surfaces thereof with the shoulders 41 and adapted to fit within the slot 31 of the rotary arrow 3. Outwardly of the cylindrical adjustment parts 40, the external cylindrical parts or basic parts 42 respectively of the propellers 4a and 4b having a plurality (four in the illustrated embodiment) of vanes 41 fixed thereon, are placed through a means of connecting arms 43 so that the coloring liquid in the dyeing chamber 2 is released and circulated in a direction as indicated by the signal of an arrow in Figure 1. The connecting arms 43 which serve to connecting the cylindrical adjustment parts 40 with the basic parts 42 of the thrusters 4a and 4b, are separated with the openings 44. These openings 44 communicate with the openings 54 and 64 that are formed in the protective members 5a and 5b and the spool 6 as will be specifically described below to form return paths for the coloring liquid in circulation, as shown in Figure 1. The protective members 5a and 5b are set to approximate closely to the opposite end portions of the spool 6 and formed from the internal cylindrical parts or cylindrical adjustment portions 50 and the outer cylindrical parts or basic parts 52 equal in diameters respectively to the cylindrical adjustment parts 40 and the basic parts 42 of the propellers 4a and 4b, and support rods 55 projecting radially from the peripheries of the basic portions 52 and each adapted to form a void reticular space. The shoulders 51 adapted to fit within the slot 31 of the rotary arrow 31 are formed within the cylindrical adjustment portions 50. The cylindrical setting parts 50 and the basic parts 52 are interconnected with a plurality of connecting arms 53. The connecting arms 53 are mutually separated with intervention openings 54. These openings 54 communicate with the openings 44 and 64 in the propellers 4a and 4b and the spool 6 so as to form return paths for the coloring liquid being circulated. The protective members 5a and 5b constructed as described above are seated on the opposite end portions of the spool 6 and are positioned in order to prevent the roll of an article 100 to be dyed from being laterally crushed by the impact of the jets of the coloring liquid formed by the rotation of the propellers 4a and 4b. The protective members 5a and 5b can be formed as two separate pieces as illustrated in Figure 2. Otherwise, they can be formed on the opposite lateral end portions of the spool 6 integrally therewith in the form of tabs that are provided with rods of support that form an empty reticular space. In this case, the blades 45 of the propellers 4a and 4b and the tabs should be placed as separate layers through a distance marked to protect the jets of the coloring liquid against any turbulence.

The spool 6 is intended to allow the article 100 to dye such as a closure tape for a zip fastener or a hook and loop fastener that is made of narrow fabric, has been wound thereon. The manner in which the central part thereof with the internal cylindrical part or cylindrical adjustment part 60 is adapted to fit around the rotary arrow 3 is provided. On the internal surface of the cylindrical part 60, the shoulder 61 is formed in the same manner as in the thrusters 4a and 4b and the protective members 5a and 5b and fits within the slot 31 of the rotary arrow 3. Several connecting arms 63 are projected from the periphery of the cylindrical adjustment portion 60 and connected with an outer cylindrical portion or a basic portion 62 where the dyeing article 100 is to be wound. The connecting arms 63 are mutually separated with openings 64. These openings 64 communicate with the openings 44 and 54 in the thrusters 4a and 4b and the protective members 5a and 5b, to form return paths for the coloring liquid that is being made circular. Figure 3 illustrates the spool 6 placed in a state having therein wound a hook and loop fastener as a concrete example of the narrow fabric of the article 100 for dyeing. Since the hook-and-loop fastener has hooks and / or hooks raised as the coupling elements from the surface of the basic fabric thereof, these coupling elements have a tendency in particular to deform during the course of dyeing. In the dyeing apparatus of the present invention, since the roll of the hook and loop fastener is dyed causing the jet of colored liquid to penetrate the rolled closure from the side side thereof, the dyeing is achieved without crushing the hooks and / or loops. Therefore, the dyeing apparatus can provide the optimum method for dyeing for the hook and loop closure. The thrusters 4a and 4b, the protective members 5a and 5b and the spool 6 are replaceable so that those having openings that fit just for the specific amount of the dyeing article 100 to be wound on the spool 6 can be selected. for service. When the article 100 for dyeing is present a small amount, for example, the spool 6 which is constructed in such a way as to provide large volumes of the opening 64 namely for inserting large intervals between the cylindrical adjustment part 60 and the 62, and the propellers 4a and 4b and the protective members 5a and 5b that are constructed to have their respective openings 44 and 54 enlarged to conform to the opening 64 of the spool 6 are used so that the article 100 for dyeing can be tightly wound in the outer perimeter of the spool 6 and can consequently be dyed with a small amount of the coloring liquid near the bottom of the chamber 2 for dyeing as illustrated in Figure 4. By preparing several sets of thrusters 4a and 4b, members 5a and 5b guards and reel 6 having openings thereof varied in proportion to the varying amounts in perspective of the article for dyeing and using the As properly replaced, therefore, the dyeing apparatus of the present invention can dye a particular article with the coloring liquid of an amount that simply fits the quantity of the article and consequently can lower the cost of production. The first embodiment described above represents the case where a reel 6 is fixed on the rotary arrow 3. By placing two reels 6a and 6b fixed on a rotating arrow 3a inside the container for dyeing as illustrated in Figure 4, fabrics of different widths can be dyed simultaneously. It is also permissible to divide the interior of a vessel Ib for dyeing with partitions 20a and 20b in a plurality of chambers 2a, 2b and 2c for dyeing to place through them a rotary arrow 3b to fix the propellers 4a and 4b, the protective members 5a and 5b and a spool 6 on the common rotational arrow 3b separately within the dyeing chambers, as illustrated in Figure 5, and dye the articles with the coloring liquids of different colors in the plurality of dyeing chambers. Figure 4 and Figure 5 respectively represent the second and third embodiments of the dyeing apparatus of the present invention. The dyeing apparatus illustrated in Figure 4 differs from the first embodiment described above with respect to two reels 6a and 6b, two pairs of (a total of four) protective members 5a and 5b placed separately on opposite sides of the reels and three thrusters 4a, 4b and 4c placed two on the outside and one between the reels 6a and 6b that are fixed to the common rotating arrow 3a and further that a cover 16 that can be freely opened and closed to an opening part 15 formed as extending is fixed through the space between the reels 6a and 6b above the cylindrical wall of the container the to dye. The component members of the dyeing apparatus, however, are identical in basic structure to those of the first embodiment. In the case of the dyeing apparatus of the present embodiment, since the reels different in length from one another as illustrated in Figure 4 have been used, two articles 100a and 100b differing in width can be dyed at the same time. When the dyeing apparatus is constructed to use a plurality of reels of equal length, it can dye a plurality of items equal in width at the same time. The operation of the winding of the articles 100a and 100b on the reels 6a and 6b and that of the unwinding thereof from the reels 6a and 6b can be carried out directly through the opening part 15 as indicated by the alternative line of a dash and two dots in Figure 4 after lid 16 has been opened. Otherwise in the same manner as in the first embodiment, these operations can be carried out after the closure 13 has been opened and the reels 6a and 6b have been removed or removed from the rotary arrow 3a. In the dyeing apparatus illustrated in Figure 5, a container Ib for dyeing a closed cylinder is formed comprising a cylindrical wall 11b and side walls 12a and 12b each fixed to the opposite end portions of the cylindrical wall 11b. The container Ib for dyeing has within it divided with two partitions 20a and 20b in three chambers 2a, 2b and 2c for dyeing. In each part of the common rotational arrow 3b placed within each of the dyeing chambers, a spool 6 and two protective members 5a and 5b and two thrusters 4a and 4b placed separately on opposite sides of the spool 6, are fixed from the same way as in the first modality. Then, the opening parts 15a, 15b and 15c are formed in the cylindrical wall 11b respectively above the dyeing chambers 2a, 2b and 2c and the lids 16a, 16b and 16c are also fixed in the respective opening parts mentioned above to open and close freely. In this case, since the container Ib for dyeing is kept in a closed state without being provided with a closure as shown in Figure 1, respectively communication openings 21a and 21b are formed in the upper parts of the partitions 20a and 20b so that uniform pressure is retained within the dyeing chambers while dyeing is being carried out therein. In the dyeing apparatus constructed as described above, the operation of winding the articles 100 on the reels 6 thereof from the unwinding thereof from the reels 6 is achieved after the covers 16a, 16b and 16c, placed respectively above the cameras 2a, 2b and 2c for dyeing have been opened in the same manner as in the embodiment of Figure 4. In the dyeing chambers 2a, 2b and 2c, the dyeing pipes 71a, 71b and 71c that are respectively provided are connected respectively. with valves 73a, 73b and 73c and dye liquid supply pipes (not shown). Now, the dyeing by use of the dyeing apparatus of the present invention will now be described with reference to Figure 1. First, the article 100 for dyeing is wound on the reel 6 which conforms to the quantity of the article 100. Then, the propellers 4a and 4b and the protective members 5a and 5b having openings 44 and 54 that conform to the abatement 64 of the spool 6, are fixed in the sequence illustrated in Figure 2 on the rotary arrow 3 in the container 1 for dyeing. After the leading end of the rotary shaft 3 has been closed by screwing the stop member 33 into it, the closure 13 of the dyeing container 1 is closed and the valve 72 in the dyeing liquid feed line 70 is opened to to supply the coloring liquid until it reaches the level indicated in L_, shown in Figure 1. Then, a heating means such as steam is supplied through the supply pipe 75 of the heating medium to the heating portion 74 for raising the temperature of the dye liquid, and the rotary arrow 3 is rotated in the motor 7. As a result, the dye liquid in the dyeing chamber 2 of the dyeing container 1 is driven by the front propeller 4a in the direction of the dye signal. the arrow shown in Figure 1 is passed through the protective member 5a and is caused to collide against the lateral end portion of article 100 to dye what has been enrobed On the reel 6, it is passed to the article, discharged from the opposite side thereof, is propelled backwards by the rear propeller 4b and returned to the front through the flow paths formed by the openings 44. , 54 and 64 of the thrusters 4a and 4b, the protective members 5a and 5b and the spool 6 fixed to the rotary arrow 3, thus forming a circulation stream of the coloring liquid for dyeing. After the article has been dyed at a stated temperature through a duration mentioned by the above-described coloring liquid circulation stream, the valve 73. in the discharge line 71 of the coloring liquid connected to the bottom of the container 1 for dyeing is open to discharge the coloring liquid and the closure 13 is opened to allow the removal of the spool 6 together with the propellers 4a and 4b and the protective members 5a and 5b from the rotary arrow 3. The item dyed as a final product is unwound from reel 6 to complete the dyeing. During the dyeing operation, the rotation of the rotating arrow 3 can be periodically reversed to change the flow of the dye liquid in the direction opposite to the direction indicated by the arrow in Figure 1, and causes the dye liquid to penetrate the article 100. for dyeing or winding on the spool 6 from the lateral end part on the opposite side. Since changing the direction of periodic rotation of the rotary arrow 3 causes the article wound on the spool to be tightened by normal rotation and loosen by reverse rotation, the penetration of the coloring liquid into the article will be improved and the article It will stain quickly and evenly. In this way, the dyeing apparatus of the present invention can dye a particular article at a low bath ratio or a low liquid ratio because the operating mechanism thereof is to use the propellers 4a and 4b to force the liquid colorant to circulate, collide with the article in the lateral direction and pass through termination through it. further, since the dyeing is implemented by the collision of the coloring liquid against the lateral end part of the roll of the article for dyeing, and particularly since the coloring liquid is made, to pass by penetration through the rolled layer of the narrow fabric that has a smaller thickness from the lateral end portion, the dyeing towards which it is directed can be effected more quickly and uniformly than when the coloring liquid is caused to penetrate the rolled layer from the side of the peripheral surface having a thickness of greater layer. In the case of the dyeing apparatus shown in Figure 4, even though the article for dyeing is present in a small amount since the rolled part of the article is closely next to the periphery of the reel 6 as shown in Figure 4, the coloring liquid in this small quantity has the level of same indicated by the signal L2 is sufficient to achieve the desired dyeing. Further, since the openings 44, 54 and 64 of the propellers 4a, 4b and 4c, and the protective members 5a and 5b and the reels 6a and 6b are formed in large sizes, they form ample flow paths for the circulation of coloring liquid and they present no impediment to the flow of the coloring liquid. Two reels 6a and 6b different in width to allow the articles to be dyed to be wound therein can be fixed as placed parallel to the rotary arrow 3a and as illustrated in Figure 4. Alternatively, the same size reels used to wind the articles can be fixed as placed parallel to the rotary arrow. It is also permissible to divide the interior of the dyeing container into various chambers 2a, 2b and 2c for dyeing and to allow a plurality of the reels 6 placed separately in the different dyeing chambers to be fixed on the common rotational arrow 3b as illustrated in FIG. Figure 5, to dye the articles in different colors in the different dyeing chambers. Lids 16, 16a, 16b and 16c can be fixed to open and close freely in the upper parts of the dyeing containers as illustrated in Figure 4, and in Figure 5, so that these dyeing articles can be rolled up and unwound. from the reels 6, 6a and 6b which remain fixed in the meantime in the rotating arrows 3a and 3b. Although several preferred embodiments of the invention have been shown and described, it will be clearly understood that the invention is not limited thereto but can be encompassed in different ways and practiced in another way. Although the first embodiment shown in Figure 1 represents a case where the propellers are positioned on each of the opposite sides of the reel, a propeller can be placed on one side of the reel. In the same way, the numbers of reels and propellers that are to be mounted on the rotary arrow can be selected arbitrarily. The embodiments described, therefore, should be considered in all respects as illustrative and not restrictive, the scope of the invention having been indicated by the appended claims rather than by the foregoing description, and all changes remaining within the scope of the invention. meaning and scale of equivalence of the claims, therefore, are intended to be covered in this.
