Description

Detailed Description of the Invention [Industrial Field of Application] The present invention relates to pantaste towing and underwear, in which articles to be dyed are equally stored one bag at a time in a plurality of dyeing tanks, and dyeing is carried out by sequentially inverting the dyeing tanks. This invention relates to a method and apparatus for dyeing knit products such as sweaters.

BACKGROUND ART Conventionally, drum dyeing methods and jet dyeing methods are generally known as methods for dyeing knit products such as pantyhose socks.

The drum dyeing method consists of a fixed outer dyeing tank and a dyeing drum inside which is formed into a drum shape with a perforated plate and partitioned into a plurality of chambers through which the dye solution can flow through each other. The dyeing drum is rotated by a motor, and the dyeing drum is loaded with a plurality of bags of items to be dyed, such as pantries, in each chamber in a well-balanced manner. After the liquid is injected into the middle of the dyeing drum, it is automatically reversed at regular intervals to allow the dye liquid to flow.During dyeing, both the object to be dyed and the dye liquid move, ensuring that the dye liquid is uniform. It penetrates into the dye and dyes the dyed object evenly.

In the liquid jet dyeing method, a basket containing a large number of bags to be dyed is pushed uniformly into a dyeing tank that is designed to circulate the liquid flow, and the liquid flow of the dye solution is circulated around the dyed items in the basket. The object to be dyed is dyed in a stationary state.

Problems to be Solved by the Invention However, the conventional methods have the following drawbacks.

In the drum dyeing method, (1) the dyeing drum is filled up to the middle with dye liquor and has a high bath ratio of 15:1 to 20:1, so a large amount of energy is required to heat the dye liquor; consume.

(2) As the dyeing drum rotates and the dyed object moves, the dyed object may be pulled, tangled, scratched, etc.

In the liquid dyeing method, (1) If a large number of bags to be dyed are not arranged uniformly in a basket inserted into a dyeing tank, the flow of the dye solution will vary and uneven dyeing will occur. Furthermore, in order to prevent uneven dyeing, the objects to be dyed must be arranged uniformly within the basket, which requires skill and extra time.

Furthermore, in all conventional dyeing methods, the objects to be dyed are placed in bags and stacked or gathered together and stored in a dyeing tank, so the penetration of the dye solution into the objects to be dyed is uneven, and in order to obtain a uniform dyeing effect, it is necessary to Requires considerable staining time (usually 2-3 hours).

The object of the present invention is to provide a method and apparatus for dyeing knit products which eliminates the various drawbacks mentioned above.

Means for Solving the Problems The method and device for dyeing knit products of the present invention includes a circulation member that circulates a plurality of dyeing tanks inside an outer dyeing tank in which a dye solution can be stored at the bottom. A plurality of dyeing tanks are arranged around the circulation member so as to go around the circulation member at appropriate intervals, and the dyeing tank is rotated eccentrically between two discs of the circulation member. It is provided so that it can be freely supported and always maintained in a horizontal state, and the dyeing tank is fixed at the top position of the circulation member by a clutch mechanism attached to the dyeing tank.
Furthermore, by providing the plurality of dyeing tanks so as to allow the dye solution stored at the bottom of the outer dyeing tank to be circulated by sequentially passing through the dye solution stored at the bottom of the outer dyeing tank by rotating the circulation member, , the articles to be dyed are evenly accommodated in one bag at a time, and as the circulation member is operated at low speed, the dyeing tank is released from its fixation and, while maintaining a horizontal state, is sequentially submerged into the dye solution stored at the bottom of the outer dyeing tank. , then the operation of sequentially escaping from the dye liquor, and the operation of fixing the dyeing tank at the top position of the circulation member, sequentially submerging it into the dye liquor while maintaining the fixed state, and then sequentially escaping from the dye liquor. Each time the dyeing tank is repeatedly fixed and released, the dyed object is turned over and the dyed object is immersed and drained.

A particular feature of the present invention is that the object to be dyed is divided into a plurality of equal parts and placed in bags, one bag is placed in each dyeing tank, and each dyeing tank is released from its fixation and placed in a horizontal state. The dyeing tank is fixed at the top position of the circulation member, and the dyeing tank is fixed at the top position of the circulation member, and the dyeing tank is fixed at the top position of the circulation member, and the By repeating the process of sequentially submerging the object into the dye solution and then allowing it to escape from the dye solution, each object to be dyed is sequentially reversed and slowly turned over to ensure that the state of contact between the object and the dye solution is the same on the top and bottom. The point is that the dyeing effect has been increased.

23 is a disk constituting the circulation member B, and 24 is an arm that connects the shaft 12 and the disk 23 and supports the disk.

The above discs are spaced two times apart as shown in Figure 2.
A plurality of dyeing tanks C, C are arranged between the respective disks 23, 23 so as to go around the outer periphery of the disk 23 shown in FIG. 1 at equal intervals, It is rotatably supported by a shaft 25.

The dyeing tank C has a box shape as shown in Fig. 3, and the upper surface of the box has a lid 26 made of a perforated plate into which the dyed object 1 can be inserted and closed, and the lower surface has a lid 26 for draining the dyed object. A porous plate 27 is fixed.

Further, as shown in FIG. 3, the dyeing tank C is rotatably supported by a shaft 25 between the two discs 23, 23 of the circulation member B, and its attachment position is the fourth one.
As shown in the figure, the dyeing tank C is eccentrically located above the center position by a dimension E, so that the center of gravity is located below, and the dyeing tank C is always in a horizontal state regardless of the presence or absence of dyed material.

Next, the clutch mechanism will be explained.

The clutch mechanism D is constructed integrally with the shaft 25 by fitting a brake wheel 30 to one end of the shaft 25 supporting the dyeing tank C with a key 31, as shown in FIGS. 5 to 7. It is rotatably supported by a bearing 32.

On the other hand, the two sets of split annular holding frames 33, 33 have their respective lower ends implanted in the disc 23 with pins 34, and are supported so as to be able to open and close using the pins as fulcrums.

A brake piece 35 is fixed to the inner peripheral surface of the holding frame so that the brake wheel 30 can be gripped from the outside.

Further, a substantially egg-shaped cam 36 with a shaft is interposed above the holding frame 33 and between the two sets of holding frames,
As shown in FIG. 7, one end of the cam is inserted and held in the bearing 37 of the disc 23, and the other end of the cam 36 is fitted with a lever 38 so that the cam 36 can be tilted at an angle of about 90 degrees. It is set up in

Further, at a position slightly below the cam 36 in the holding frame 33, a bolt 39 is inserted into the holding frames 33, 33, as shown in FIG. There is. When the cam is brought down to the state shown in FIG. 5, the action of the spring 40 causes the two sets of holding frames 33, 3 to
3 is operated in the closing direction, and the brake piece 35 of the holding frame is pressed against the brake wheel 30 to fix the shaft 25, thereby fixing the dyeing tank C integrally formed with the shaft.

Further, when the cam 36 is tilted to the state shown in FIG. 6, the cam 36 resists the action of the spring 40,
The gap between 3 and 33 is widened, and the brake piece 35 is connected to the brake wheel 30.
The dyeing tank C can be freely rotated by releasing the restraint.

The operation will be explained using the above configuration.

First, a dyeing bag is prepared by inserting, for example, 10 decals of dyed items such as pantyhose into each bag. Next, the dyeing solution is supplied to the outer dyeing tank A and heated to the dyeing temperature.

On the other hand, the motor 10 is driven to rotate the circulation member connected to the motor by the chain 14, thereby rotating the dyeing tank C at a low speed (for example, several rotations) in the direction of the arrow in FIG.

Although the dyeing tank C moves in a circle around the shaft 12, the dyeing tank C itself is supported so that the center of gravity of the box is downward, as described above, so that it is always transported in a horizontal state.

The object to be dyed 1 is placed in one bag at a time by opening the lid 26 of the dyeing tank C from the door 8 of the outer dyeing tank A, and then closing the lid.

When all the dyeing tanks C contain the objects 1 to be dyed, the door 8 is closed and the dyeing work is started.

When the circulation member B rotates, the dyeing tank C shown on the right side of FIG. 1 is lowered in a horizontal state and submerged into the dye solution, and the dyed article 1 is immersed therein. Subsequently, the dyeing tank C is raised and lifted out of the dye solution, but the dye solution in the immersed dyed object flows out uniformly from the bottom perforated plate 27 of the dyeing tank shown in FIG. 3, and is drained.

When the dyeing tank C has completed one cycle and the dyeing tank C is located at the top as shown in FIG. 1, the air cylinder 41
is activated, the piston rod part tilts the lever 38 to the right, and as mentioned above, the cam 36 is brought into the state shown in FIG.
5 is fixed to the disc 23.

By sequentially performing this operation for each dyeing tank, the dyeing tanks are fixed in the state shown by the two-dot chain line in FIG. 1 and sequentially moved in the direction of the arrow.

Then, at the lowest position, the staining tank C is inverted from the staining tank C at the top.

That is, the lid 26 of the dyeing tank is at the top at the top position, but at the bottom at the bottom position, and therefore,
This means that the object 1 to be dyed in the dyeing tank C has been rotated approximately 180 degrees and turned over.

The object 1 to be dyed is immersed in the dye solution in an upside-down state and subjected to immersion treatment.

Next, the dyeing liquid in the immersed dyed object flows out from the perforated plate of the lid 26 shown in Fig. 3 and is drained, and then the dyeing tank C is shown in Fig. 1. When it moves to the top position, the right air cylinder 42 is actuated, the piston rod part tilts the lever 38 to the left, and the clutch mechanism D is reversely operated as described above to release the fixation of the staining tank C and rotate it. By making it movable, the dye tank C is allowed to submerge and pass through the dye solution while always maintaining a horizontal state.
The above-mentioned soaking and draining processes are performed.

At this time, the state of the dyeing tank C has moved to the state shown by the solid line in FIG. 1, and therefore the object to be dyed is not turned over.

By repeating the above operations, the dyed object will be inverted when the dyeing tank C is fixed, and will not be inverted when it is freely rotatable, so that the immersion and draining processes of the dyed object can be performed evenly from the top and bottom under the same conditions. It can be done with

When the dyeing is completed, the automatic valve 4 is opened to discharge the dye solution.

Next, the automatic valve 4 is closed and water is supplied to perform the washing process, and then the fixing agent is supplied to perform the fixing process. When the entire process is completed, the automatic valve 4 is opened and all of the liquid in the outer dyeing tank A is drained. It is discharged, and then the dyed articles are taken out one by one to complete one process.

Although not shown, the dyeing tank can be rotated by operating the clutch mechanism D when the dyeing tank is at the lowest position or at a position raised above the dye solution depending on the type of material to be dyed and the state of bagging. It is possible to change the state in which the dyed object is immersed and drained in the dyeing tank C.

Effects of the Invention As described above, according to the present invention, the following effects are achieved.

The articles to be dyed are equally stored one bag at a time in a plurality of dyeing tanks which are supported at appropriate intervals around the circulation member so as to maintain a horizontal state, and which are fixed and removable at the top position. With the low-speed circulation operation of the circulation member, the dyeing tank is released from its fixation, and while maintaining a horizontal state, the dyeing tank is sequentially submerged into the dye liquid stored at the bottom of the outer dyeing tank, and then sequentially released from the dye liquid; Each time the dyeing tank is fixed and released, the dyeing tank is fixed at the top position of the circulation member, and the dyeing tank is sequentially submerged in the dye solution while maintaining the fixed state, and then released from the dye solution in sequence, each time the dyeing tank is fixed and released. Since the dyed objects are turned over at the same time and immersed and drained, the dyed objects stored in the dyeing tank are turned over and turned inside out at a timely and slow pace for immersion and draining. The conditions of contact between the dyed object and the dye solution in the tank are the same on the top and bottom,
Therefore, it is possible to prevent the dyed material from being tangled, tangled, scratched, etc. which conventionally occurred in the drum dyeing method, and the yield of the product is improved.

Furthermore, unlike the conventional flow dyeing method and drum dyeing method, the dyed objects are not stacked or collected in a dye tank, so that the dyeing is uniform and the dyeing time can be significantly shortened.

In addition, since dyeing can be done with the dye liquid stored at the bottom of the outer dyeing tank, the bath ratio is lower than that of conventional liquid flow and drum dyeing machines.
