  With the above configuration, the following effects can be achieved.

  According to the first technical solution of the present invention, while the rotating shaft is rotating, the beam around which the workpiece is wound rotates together with the rotating shaft, so that a centrifugal force is generated by pushing the staining solution, and the staining solution is removed from the beam. The dyeing liquid is held in a ring shape along the inner peripheral surface (inner wall) of the staining container. In addition, one end is connected to the peripheral wall, the other end is connected to the rear wall, and a circulation path is provided for flowing the staining solution from the peripheral region along the peripheral wall to the central region of the staining container, so that staining is performed by centrifugal force.

On the right.

  As shown in FIGS. 1-5, the dyeing machine of this invention consists of the cylindrical dyeing container 2 which stores the beam 1 which is a cylindrical winding frame, and the dyeing | staining liquid. The beam 1 has a cylindrical beam body 11 that is long in the front-rear direction. The beam body 11 includes a large number of first holes 13 formed on the peripheral surface. The first hole 13 penetrates the circumferential surface of the beam body 11 in the radial direction of the beam body 11. The beam 1 has front and rear flanges 12 provided at the front end and the rear end of the beam main body 11 and extending in the radial direction of the beam main body 11. Further, the beam 1 has a projection 14 provided on the front flange 12 and projecting forward. An object to be processed is wound around the peripheral surface of the beam body 11. The flange 12 serves as a wall so that the object to be processed does not come off the front end portion and the rear end portion of the beam body 11. Two protrusions 14 are arranged at 180 ° intervals in the circumferential direction of the beam 1. The dyeing solution is dyed into the workpiece through the first hole 13. The object to be treated is a textile product. In the case of the present embodiment, as an example of the object to be processed, a fastener chain F in which fastener elements are fixed along the edge of the tape is given.

  The staining container 2 has a peripheral wall 5 that is long in the front-rear direction, and a rear wall 4 that closes the rear end of the peripheral wall 5 on one end side in the axial direction. A rotating shaft 3 extending in the front-rear direction is disposed inside the staining container 2. The rotating shaft 3 is disposed so as to penetrate the rear wall 4 and rotate in a watertight manner with respect to the rear wall 4. A circular lid 8 is attached to the front end portion on the other axial end side of the peripheral wall 5 so as to be opened and closed by sliding in the vertical direction. The rear wall 4 has a cylindrical convex portion 41 extending in the diametrical central region on the side opposite to the peripheral wall 5. The convex portion 41 has a cylindrical portion 41a that is long in the front-rear direction and an end portion 41b that closes the rear end portion of the cylindrical portion 41a. The rotating shaft 3 passes through the end 41b. The dyeing vessel 2 is provided with a circulation path 30 that connects the peripheral wall 5 and the rear wall 4. The circulation path 30 includes a pipe 31 having one end penetrating watertightly through the center in the front-rear direction of the upper peripheral wall 5 of the staining container 2 and the other end penetrating watertightly through the cylindrical portion 41 a above the convex portion 41. Details of the circuit will be described later.

  Inside the staining container 2, a cylindrical beam accommodating member 7 having a diameter larger than that of the beam 1 and accommodating the beam 1 is disposed. The beam housing member 7 has a cylindrical body 71 that is long in the front-rear direction and a rear plate 72 that closes the rear end of the body 71. The rear plate 72 serves as a stopper that comes into contact with the beam 1 and stops the beam 1 from moving toward the rear of the staining container 2 when the beam 1 is accommodated in the beam accommodating member 7. The rotating shaft 3 passes through the rear plate 72. The beam accommodating member 7 has a rear plate 72 fixed to the rotating shaft 3 and rotates with the rotation of the rotating shaft 3.

  A disc-shaped pressing member 15 that connects the beam 1 and the rotating shaft 3 is attached to the front side of the rotating shaft 3 so that the beam 1 rotates together with the rotating shaft 3. A center hole 16 into which the tip of the rotary shaft 3 is inserted is provided at the center of the pressing member 15. In addition, two elongated holes 17 into which the protrusions 14 provided on the beam 1 are inserted are provided in the disc portion of the pressing member 15. After the beam 1 is accommodated in the beam accommodating member 7 and the pressing member 15 is installed on the rotating shaft 3, the beam 1 is fixed to the rotating shaft 3 with a stopper (not shown) such as a screw. In this embodiment, the beam accommodating member 7 and the pressing member 15 are formed with fixing means for fixing the beam 1 to the rotating shaft 3. When the rotating shaft 3 rotates, the presser member 15 fixed to the rotating shaft 3 also rotates. At this time, the inner surface of the elongated hole 17 of the pressing member 15 pushes the protrusion 14 of the beam 1 in the rotation direction, so that the beam 1 rotates. As the beam 1 rotates, a centrifugal force is generated by pushing the staining liquid, and the staining liquid flows in a direction away from the beam 1 so that the staining liquid is held in a ring shape along the peripheral wall 5 of the staining container 2. .

  The long hole 17 is formed long in the radial direction of the pressing member 15. The reason for this is that when the amount of winding of the fastener chain F is small, the beam 1 uses another beam in which the diameter of the beam main body 11 (the portion around which the fastener chain is wound) is increased. May shift. Even in such a case, the protrusion 14 can be inserted into the elongated hole 17.

A first roller 21 is connected to the rear end of the rotating shaft 3. When the first roller 21 rotates, the rotary shaft 3 connected to the first roller 21 also rotates. A second roller 22 connected to the first roller 21 via the belt 23 is connected to the drive shaft 24 of the motor M. When the drive shaft 24 rotates, the second roller 22 connected to the drive shaft 24 also rotates. When the second roller 22 rotates, the first roller 21 connected to the second roller 22 through the belt 23 rotates. Thereby, the rotating shaft 3 is rotated by driving the motor M. The motor M is connected to a control unit C that sets the amount of the dyeing liquid and the number of rotations of the rotary shaft 3 based on the amount of the fastener chain F wound around the beam 1. Specific examples of settings in the control unit C are shown in the following table.

  Based on the amount of the fastener chain F wound around the beam, the control unit C can set the amount of the staining liquid and the number of rotations of the rotation shaft. As shown in the above table, when the weight of the object to be processed is small, the amount of the staining liquid is small and the number of rotations of the rotation shaft is set to be small. And when the weight of a to-be-processed object is large, the quantity of dyeing | staining liquid is large and the rotation speed of a rotating shaft is set many. Specifically, when the weight of the object to be processed is smaller than 400 g, the amount of the staining liquid is increased and the number of rotations of the rotation shaft is increased as the amount of the object to be processed increases. Thereby, it is possible to control the amount of the dyeing solution most suitable for the amount of the fastener chain F and the number of rotations of the rotary shaft 3, and the dyeing solution and the power consumption are not wasted. That is, by setting in the control unit C, even with a small amount of dyeing liquid, the dyeing liquid can be ring-shaped, and the dyeing liquid can easily penetrate into the fastener chain F wound around the beam 1, and the fastener chain F can be dyed beautifully.

  In addition, when the weight of the object to be processed is equal to or greater than a predetermined amount, the control unit C sets the amount of the staining liquid and the number of rotations of the rotation shaft to be constant. Specifically, when the weight of the object to be processed is 400 g or more, the amount of the staining liquid and the rotational speed of the rotating shaft are made constant at a larger value than when the weight of the object to be processed is smaller than 400 g. It is set. The reason for this is that even if the weight of the object to be processed increases to a predetermined weight or more, if there is a certain amount of dyeing liquid and a certain number of rotations, the dyeing liquid can be ring-shaped and the dyeing liquid penetrates into the fastener chain F. It is because it is made to do.

  A number of second holes 26 are formed in the peripheral surface of the beam housing member 7. The second hole 26 penetrates the peripheral surface of the beam housing member 7 in the radial direction of the beam housing member 7. The second hole 26 is a hole through which the dyeing solution having passed through the first hole 13 and the fastener chain F is passed. Further, there is a gap 27 between the beam housing member 7 and the peripheral wall 5 of the staining container 2.

  In order to dye as many fastener chains F as possible by one dyeing, it is necessary to wind a long fastener chain F around the beam 1. Thereby, the layer of the fastener chain F wound around the beam 1 is thickened, and the layer of the fastener chain F is approaching the beam accommodating member 7 as shown in FIG. The beam accommodating member 7 is disposed close to the inner wall of the staining container 2 in order to avoid contact with the fastener chain F. Thereby, the gap 27 between the beam accommodating member 7 and the staining container 2 becomes small. When the gap 27 becomes small, the fluidity of the dyeing liquid in the dyeing vessel 2 is lowered, and color unevenness occurs in the object to be dyed.

  In order to prevent the above-described problem, the present invention is provided with a circulation path 30 having one end connected to the peripheral wall 5 and the other end connected to the rear wall 4. More specifically, one end of the circulation path 30 communicates with the gap 27 at the middle portion in the front-rear direction of the peripheral wall 5 on the upper side of the peripheral wall 5, and the other end of the circulation path 30 extends from the diametrical central region of the rear wall 4 to the peripheral wall. 5 communicates with the inside of the staining container 2 through a cylindrical convex portion 41 extending in the direction opposite to the direction 5.

  When the beam 1 rotates together with the rotating shaft 3, the circulation path 30 automatically and automatically removes the staining liquid existing in the gap 27 along the inner surface of the peripheral wall 5 of the staining container 2 from one end by centrifugal force. It can be continuously received in the circulation path 30 and returned from the other end to the central region in the convex portion 41. In the interior of the staining container 2, since the staining solution is directed from the central region to the peripheral region by centrifugal force, the central region is slightly negative pressure. Therefore, the dyeing liquid that has entered one end of the circulation path 30 is likely to be discharged from the other end to the negative pressure center region. The circulation of the dyeing liquid from the peripheral region to the central region can increase the fluidity of the dyeing solution in the dyeing vessel 2, thereby making the fastener chain F dyeing more uniform.

  An injection path 9 for inserting the staining solution into the staining container 2 is connected to the cylindrical portion 41 a of the convex portion 41. The injection path 9 is installed on the upper side of the convex portion 41. As shown in FIG. 1, the other end of the pipe 31 and the injection path 9 are connected to the cylindrical portion 41 a of the convex portion 41 so as to be lined up and down. In addition, a discharge path 10 for discharging the staining liquid from the staining container 2 is connected to the peripheral wall 5. The discharge path 10 is installed on the lower side of the staining container 2.

  Next, dyeing by the dyeing machine of the present invention will be described. When the beam 1 is inserted into the staining container 2, the rotating shaft 3 is inserted into the beam 1, and the beam 1 is accommodated in the beam accommodating member 7.

  FIG. 12 is a schematic diagram showing a state in which the staining liquid flows in the staining container 2 when the rotating shaft 3 rotates. First, the beam 1 around which an appropriate amount of the fastener chain F is wound is inserted into the staining container 2 and the lid 8 is closed. After injecting a predetermined amount of staining solution as shown in FIG. 12A from the injection path 9 into the staining container 2 by a valve (not shown), the injection path 9 is closed. Next, the rotating shaft 3 is rotated by the motor M. Thereby, the beam 1 around which the fastener chain F is wound also rotates, and at this time, the dyeing liquid is in a state shown in FIG. After the dyeing liquid passes through the first hole 13 of the beam 1 and penetrates into the fastener chain F, the dyeing liquid passes through the second hole 26 of the beam accommodating member 7 and is between the beam accommodating member 7 and the peripheral wall 5 of the staining container 2. It circulates through the gap 27, passes through the state shown in FIG. 12 (c), and finally becomes a ring shape as shown in FIG. 12 (d). In the state of FIG. 12D, the staining liquid present in the gap 27 is circulated into the convex portion 41 of the rear wall 4 through the circulation path 30. That is, the staining solution is held in a ring shape along the peripheral wall 5 of the staining container 2 while the rotating shaft 3 is rotated. This staining solution is circulated by the circulation path 30 using centrifugal force. Returned to the center side of the staining container 2.

  Since the injection path 9 is provided on the convex portion 41 extending to the side opposite to the peripheral wall 5 of the staining container 2, when the centrifugal force is applied to the staining liquid, the staining liquid is prevented from entering the injection path 9. ing.

  Further, the staining liquid along the peripheral wall 5 of the staining container 2 in a ring shape passes through the circulation path 30 connected to the convex portion 41 from one end of the circulation path 30 connected to the central portion in the front-rear direction of the peripheral wall 5 of the staining container 2. After flowing to the other end of the dye, it returns to the center of the staining container 2. Then, the staining liquid flows from the center of the staining container 2 toward the inner wall side of the staining container 2.

  Since the circulation path 30 is connected to the central portion in the front-rear direction of the peripheral wall 5, it is possible to suppress the circulation of the staining liquid in the front-rear direction of the staining container 2, and the circulation path 30 is formed in the diameter direction of the rear wall 4. Since it is connected to the cylindrical portion 41a of the convex portion 41 formed in the central region, the staining liquid along the peripheral wall 5 of the staining container 2 in a ring shape is surely returned to the center of the staining container 2, Furthermore, the fluidity of the dyeing liquid is improved, and the dyeing liquid can easily penetrate the fastener chain F wound around the beam 1. And after such dyeing | staining is performed for the predetermined time, rotation of the rotating shaft 3 by the motor M is stopped. The discharge path 10 was opened by a valve (not shown) to discharge the dyeing solution, and the dyeing was completed.

  The beam 1 is accommodated in the beam accommodating member 7 and can be rotated together with the beam accommodating member 7. Further, by providing the second hole 26 in the beam accommodating member 7, the staining liquid passes from the first hole 13 of the beam 1 through the second hole 26 of the beam accommodating member 7, so that the flow path of the staining liquid is determined. Thereby, the generation | occurrence | production of the spot which arises because the flow of the dyeing liquid is disturbed can be prevented.

  The dyeing machine of this embodiment allows the dyeing solution to penetrate into the object to be processed without using a pump, and even with a small amount of dyeing liquid, the dyeing to the object to be processed is free of spots and is beautiful. And cost can be reduced.

  Next, a dyeing machine according to a modification of the present invention will be described. The description of the modified example will be described centering on differences from the above-described embodiment, and the same members as those in the above-described embodiment will be denoted by the same reference numerals, and redundant description will be omitted.

Further, as shown in FIGS. 7 and 9, the rotating body 6 has a plurality of wings 28 extending in the radial direction with respect to the rotating shaft 3. The wings 28 are arranged at predetermined angles in the circumferential direction around the rotation axis 3. In the illustrated example, eight wings 28 are arranged at 45 ° intervals. When the beam 1 is inserted into the staining container 2, the rotating shaft 3 and the rotating body 6 are inserted into the beam 1, and the beam 1 is accommodated in the beam accommodating member 7.

  FIG. 10 is a cross-sectional view showing a state after inserting the beam of the dyeing machine of Modification 2 according to the present invention into the dyeing vessel. In FIG. 10, compared with the first modification, there is no beam accommodating member. Instead, a disk-like stopper 25 attached to the rear side of the rotary shaft 3 and a disc-like presser attached to the front side of the rotary shaft 3. The beam 1 is sandwiched and fixed by the member 29. The stopper 25 is in contact with the beam 1 when the beam 1 is accommodated inside the staining container 2, and the beam 1 is moved to the rear of the staining container 2 when the beam 1 is accommodated inside the staining container 2. Stop moving towards. The stopper 25 and the pressing member 29 are rotatable with the rotary shaft 3 so that the beam 1 rotates with the rotary shaft 3. That is, in the second modification, the stopper 25 and the pressing member 29 constitute a fixing means for fixing the beam 1 to the rotating shaft 3. Even when the beam 1 is inserted into the staining container 2, the rotating body 6 is inserted into the beam 1.
