Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an apparatus for dyeing piece articles such as skein yarn and stockings.

[Conventional technology]

Conventionally, drum-type dyeing machines and jet-type dyeing machines are generally known as techniques for dyeing piece articles such as skeins and stockings.

Furthermore, a technique for dyeing by immersing and draining the dye solution and the object to be dyed without moving them is also known, as described in JP-A-58-104260.

A drum-type dyeing machine has a fixed outer dyeing tank and a perforated plate inside to form a drum, and the inside of the drum is partitioned into multiple chambers that allow the dye solution to flow through each other. It becomes more like a drum, and furthermore,
The outer dyeing tank is equipped with a means for supplying and draining water, a means for supplying the dye and an auxiliary agent, and a means for heating the dye liquor, which is a mixture of water, the dye and the auxiliary agent, with steam or the like. It is constructed so that it can be rotated by a deceleration motor or the like.

Then, the items to be dyed, such as stockings, are separated into one bag at a time, and one dyeing bag is placed in each chamber of the dyeing drum.
Several bags to dozens of bags are placed into the chamber in a well-balanced manner, and the dye liquid is poured into the dyeing drum up to the middle of the drum, which is then automatically turned over at regular intervals to allow the dye liquid to flow automatically.

In addition, a liquid jet dyeing machine separates the items to be dyed, such as stockings, into individual bags, and stores the bags by evenly pushing them into a basket containing at least several dozen bags, in a dyeing tank installed so that the liquid flow can circulate. The dyeing liquid flow is forcibly circulated through the dyed object in the basket to dye the dyed object in a stationary state.

Furthermore, the technique described in JP-A-58-104260 is a dyeing tank which is divided into a plurality of tanks and whose bottom part is openable and closable.
After pouring the dye liquid into the tank and immersing the dyed object, the operation of draining the dye liquid and draining the dyed object is repeated in sequence for at least one tank without moving the dye liquid and the dyed object. It is dyed by dipping and draining.

[Problem to be solved by the invention]

However, these techniques have the following problems.

Drum-type dyeing machines fill the dyeing liquid up to the middle of the dyeing drum and have a high bath ratio of 1:15 to 1:20, which consumes a large amount of energy to heat the dyeing liquid. At the same time, large amounts of used dye liquor are discharged, polluting rivers. Furthermore, as the dyeing drum rotates and the dyed material moves violently, the dyed material may be twisted, tangled, and the loops of the stitches may be disrupted.
In some cases, scratches may occur, causing quality problems.

In a jet dyeing machine, if the objects to be dyed are not pushed into the basket inserted into the dyeing tank and arranged evenly, 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 requires extra time.

In the dyeing technique described in JP-A No. 58-104260, since both the dyed object and the liquid flow do not move, the water permeability of the dye liquid is limited when dyeing objects with a small number of filaments (for example, shear type stockings). If it's too good, bubble problems tend to occur. Furthermore, since it has poor permeability (here, water permeability refers to the degree to which the dye solution passes from top to bottom, and permeability refers to the degree to which the dye solution spreads within the object), Spot unevenness (partial unevenness) occurs, which is unfavorable in terms of quality.

The present invention was developed with the aim of solving the various problems mentioned above.

Furthermore, it is linked to a conveyor F for carrying out which conveys the bag of the dyed article 1 to be discharged to a dehydrator.

The carrying-in device D is an insertion hopper 30 installed on the side of the dyeing tank 3, which collects the dyed articles 1 packed in bags one by one.
A carry-in conveyor 31 arranged to convey the article to the conveyor position, and the article 1 to be dyed conveyed to the conveyor position.
and an insertion means G for inserting the bag into the insertion hopper 30, and the insertion means is connected to the chain 3.
Insert the push member 33 attached to hopper 3
It is provided so that it can make linear reciprocating motion in the 0 direction, and although it is not shown in the drawings, a device that can make linear reciprocating motion, such as an air cylinder, can also perform this function.

The carry-out device E is the same as the carry-in device D except that the conveyor 31 and the insertion hopper 30 are removed, but the push-out member 34 is used to move the bag of the dyed material 1 on the shelf board 9 into the dyeing tank 3 as shown in FIG. The length is such that it can be pushed from one side to the other, and although not shown, an air cylinder capable of reciprocating linear motion can also perform this function. In addition, at this position, the guide member B and the dyeing tank 3 are open or provided so that they can be opened when necessary, and a discharge chute 35 is provided on the side of the dyeing tank 3 on the side from which the bag of the dyed object 1 is discharged. is installed.

A conveyor F for carrying out is arranged so as to be able to receive the bag of the dyed material 1 discharged from the discharge chute 35.

The operation will be explained using the above configuration.

First, piece articles 1 to be dyed, such as skeins and stockings, are divided into a number of bags and inserted one bag at a time. Then, the bags are transported one by one onto conveyor 3.
1 at appropriate intervals. conveyor 31
The bag with the object to be dyed 1 placed on it is inserted into the hopper 30
When the bag reaches the position, the inserting means G operates and the pushing member 33 inserts the bag containing the object 1 into the hopper 30.
The shelf board 9 is pushed into the position and is waiting in position.
Insert between.

Next, drive means A is operated to drive sprocket 5.
~ Move the shelf board 9 one pitch via the chain 8 and stop the driving means A. Although this positioning mechanism is not shown, it may be a combination of a cam attached to a rotating body and a limit switch, it may be a geneva stop mechanism, it may be a rotary encoder, or it may be a known technique.

Once the bag is positioned, the above-described operation of inserting the bag of the dyed object 1 is sequentially repeated until the bag is inserted between all the shelf boards 9, and the work of inserting the bag of the dyed object 1 is completed.

Next, as a pre-treatment for the pre-coloring process, a scouring operation of the dyed object is performed in the same manner as the dyeing operation described below. When the scouring operation is completed, the object 1 to be dyed between the shelf plates 9 attached to the chain 8 is operated following the refining operation and is moved forward and backward at regular intervals.

Next, the automatic valve 18 of the water supply port 17 in the dye solution supply means H shown in FIG. 24 is operated to mix the required amount of dye and auxiliary agent to create a dye liquor, and the dye liquor is supplied to the dyeing tank 3.

Here, the dyeing liquid is supplied to the dyeing tank 3 up to the X dimension position shown in FIG. However, it is preferable that the water level is set after the dyed object 1 has passed through the dyeing tank 3 once, and that at least four bags or more of the dyed object 1 are immersed in the water.

Next, the dye liquid supplied to the dyeing tank 3 is heated by the heating means C to a temperature necessary for dyeing, and is controlled to maintain the temperature.

By doing this, the dyed object 1 passes through the heated dye liquor one after another and is immersed, and then escapes from the dye liquor and rises. Since only one bag is inserted, and moreover, it is inserted so as to cover almost the entire surface of the shelf board 9, the dye liquid contained in the dyed object 1 is inserted into the dyed object 1.
Water is drained evenly over the whole area. As shown in FIG. 1, as the object 1 to be dyed moves upward, the dye solution sequentially flows down from above to below, and at the highest position, the speed of the driving means A is controlled so that sufficient drainage can be performed. .

Then, at the highest position, the dyed object 1 is reversed and turned over as shown in FIG. 1, and then the dyed object 1 is lowered.

Then, when it reaches the lower position, it passes through the dye liquor again, but at this time, the object 1 to be dyed moves to some extent due to the resistance of the dye liquor.

Subsequently, the object 1 to be dyed is raised and the above-described operation is repeated.

By rotating the driving means A forward and backward at regular intervals, the object 1 to be dyed is also reversely rotated at regular intervals to perform dipping and draining processes.

As a result, the object 1 to be dyed is reversed between the top dead center and the bottom dead center of the dyeing tank 3, and can be reversely reversed by the reverse rotation of the driving means A.

When the dyeing work is finished, the heating of the dye solution is stopped, and the automatic valve 15 of the drain port 16 is activated to drain the dye solution, and then the automatic valve 15 is reversely operated to close, and water is supplied from the water supply port 17 for washing. Do the work or
Alternatively, a fixing process is performed to complete one process.

Next, the driving means A is controlled to position the shelf board 9 at the insertion hopper 30 and ejection chute 34 positions and temporarily stop it. Then, the device E for discharging the dyed material shown in FIG.
As a result, two bags of the dyed material are simultaneously pushed out from the left to the right as shown in FIG. 5, and the bags are discharged to the discharge conveyor F through the discharge chute 34.

Next, the pushing member 35 is returned to its original position, the driving means A is operated, the shelf board 9 is moved by one pitch, the next shelf board 9 is positioned, and the carrying out device E is operated again to move the pushing member 35. The operation of discharging the bags of dyed material is performed sequentially.

Then, as described at the beginning, the discharged and empty shelf board 9 is loaded with the dyed articles 1 one bag at a time at the carry-in device D position to prepare for the next dyeing operation.

On the other hand, the dyed article 1 discharged onto the carrying-out conveyor F is conveyed to the dehydrator, which is the next step, and is automatically fed into the dehydrator.

〔Effect of the invention〕

Since the present invention is configured as described above, the articles to be dyed can be inserted one bag at a time into a plurality of shelf boards, and the articles to be dyed can be immersed one bag at a time in the dye solution.
Each bag can be drained uniformly, and the dyeing can be done while turning over the dyed bags one by one at regular intervals.
The object to be dyed can be dyed uniformly at a low bath ratio and in a short time.

Therefore, twisting, entanglement, disordered stitch loops, scratches, etc. of dyed objects, which conventionally occur due to violent movement of dyed objects in a drum dyeing machine, are eliminated.

Furthermore, uneven dyeing of the dyed objects due to variations in the flow of the liquid in the liquid jet dyeing machine is eliminated, and the need for skill in uniformly arranging the dyed objects in the basket is also eliminated.

Furthermore, spot unevenness that occurs when dyeing objects with a small number of filaments in dyeing techniques that do not move both the dyed object and the liquid flow is eliminated.

It is possible to solve problems that have traditionally been faced, such as, and provide high-quality products.
