[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a multi-vessel liquid flow processing machine fabric detail further relates the process liquid stream multi-vessel liquid stream processor capable of performing uniform liquid treatment without increasing the circulation speed of the fabric by In addition to the liquid dyeing process for dyeing a fabric, it can be used for fabric processing such as scouring and alkali weight loss.
[0002]
[Prior art]
Currently, liquid dyeing machines for dyeing fabrics while being conveyed in a dye liquor stream are frequently used for dyeing fabrics. This liquid dyeing machine dyes rope-like fabric while circulating it in the dyeing liquid, and the cloth is circulated using the dyeing liquid flow generated by jetting the dyeing liquid from the jet nozzle. Since the tension applied to the fabric can be reduced and the risk of wrinkles being fixed at the same position is small, there is an advantage that good dyeing without rope wrinkles can be performed.
[0003]
However, when the conventional liquid dyeing machine is intended to increase the dyeing capacity by increasing the capacity of the dyeing tank in order to improve its dyeing processing capacity, the stagnation time of the fabric in the dyeing tank becomes long, For example, there is a difficulty in disturbing leveling, such as dyeing spots easily occurring due to floating of the fabric in the dyeing tank.
[0004]
Of course, if the dye liquid flow rate is increased by using a large capacity pump to further increase the circulation speed of the fabric, the stagnation time of the fabric in the dyeing tank can be shortened, resulting in dyeing spots in the dyeing tank. It is also possible to deal with it. And the increase in the flow rate of this dyeing liquid is one of the improvement directions of the liquid flow dyeing machine which has been promoted in the industry together with the reduction in the bath ratio. However, the problem of dyeing spots due to the increase in the flow rate has the adverse effect of increasing the damage to the fabric, such as the fabric being distracted or disorganized due to an increase in the nozzle injection pressure of the dye solution, and the circulation speed of the fabric is improved. the leveling of by is there was a marginal.
[0005]
[Problems to be solved by the invention]
The present invention was made in view of the above-mentioned difficulties in conventional liquid flow dyeing, and is a multi-tank liquid that can perform uniform liquid treatment without increasing the circulation rate of the fabric. It is a technical problem to provide a flow treatment machine.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail based on embodiments shown in the accompanying drawings. 1 is a schematic cross-sectional view for explaining the configuration of the multi-tank liquid flow treatment machine according to the present embodiment, and FIG. 2 is a partial view showing another embodiment of the multi-tank liquid flow treatment machine according to the present invention. It is an abbreviated schematic diagram.
[0009]
The double-tank liquid flow treatment machine of this embodiment shown in FIG. 1 is embodied as a double-tank liquid flow dyeing machine that performs a predetermined dyeing process on a fabric W that is looped by connecting both ends.
[0010]
In FIG. 1, what is indicated by reference numeral 1 is a substantially cylindrical processing tank (dyeing tank) provided with a fabric entry / exit hatch 10 at the front part. In this embodiment, a total of two processing tanks 1 and 1 are provided. They are parallel to each other in the same direction on the same plane.
[0011]
In each of these two treatment tanks 1, 1, a dye liquor that is a treatment liquid L is accumulated, and the fabric W is floated and swayed in the accumulated treatment liquid L by causing the cloth W to float and sink. In a spread state, a relaxing liquid bath is used. In addition, what is indicated by reference numeral 11 in the figure is an auxiliary reel for guiding the fabric W bathed in the relaxation liquid in each treatment tank 1 to an injection nozzle 30 of each transfer pipe 2 described later.
[0012]
In FIG. 1, what is indicated by reference numeral 2 is connected to each of the two treatment tanks 1 and 1 in the vicinity of both ends thereof, and communicates with each other to form one cloth circulation circuit C. Two transfer pipes. Each of these transfer pipes 2 and 2 communicates the front part of one of the two processing tanks 1 and 1 with the rear part of the other processing tank 1. Thus, since the two treatment tanks 1 and 1 are arranged in parallel in the same direction, these transfer pipes 2 and 2 are crossed up and down to form one roughly 8-shaped cloth circulation circuit C.
[0013]
In each of these two transfer pipes 2 and 2, the dyeing liquid as the processing liquid L is rapidly flowed by the liquid jetting of the spray nozzle 30 described below, and the fabric is obtained by using the rapid processing liquid flow. W is guided in a rope state from the front part of each processing tank 1, and the guided fabric W is liquid-conveyed to the rear part of the adjacent processing tank 1. In this way, the cloth W is conveyed by the treatment liquid flow in the transfer pipes 2 and 2 and circulates in the cloth circulation circuit C.
[0014]
In the figure, what is indicated by reference numeral 3 is a liquid flow pump for generating a rapid processing liquid flow in each transfer pipe 2. The liquid flow pump 3 sucks the processing liquid L accumulated in each processing tank 1 through conduits 31a and 31b piped to the bottom of the tank, and pressurizes the sucked processing liquid L to supply pipes 32. Through the injection nozzle 30 disposed upstream of each transfer pipe 2. In addition, what is indicated by reference numeral 33 in the figure is a heat exchanger for raising and lowering the treatment liquid L to a desired temperature, and what is indicated by reference numeral 34 is for adjusting the injection flow rate of the injection nozzle 30. It is a nozzle valve.
[0015]
In the figure, what is indicated by reference numeral 4 is a sensor for detecting the magnetic material M previously attached to the joining portion of the loop-shaped fabric W. In this embodiment, the sensor is arranged at the front part of each treatment tank 1. It is installed. Based on the detection signals of these sensors 4 and 4, the circulation speed and stagnation time of the fabric W in each treatment tank 1 are measured, and when there is a difference in the fabric stagnation time between the left and right treatment tanks 1 and 1. The stagnation time of the fabric W in each treatment tank 1 is adjusted by adjusting the liquid spray of the spray nozzle 30 and the rotation speed of the auxiliary reel 11, respectively.
[0016]
Thus, in the multi-tank liquid flow treatment machine of the present embodiment, first, the cloth entrance / exit hatch 10 of one of the treatment tanks 1 is opened, and the leading end portion of the non-loop fabric W is moved into the transfer pipe 2. The leading end of the fabric W is made to make a round in the cloth circulation circuit C using the treatment liquid flow, and then the leading end of the fabric W returned to the vicinity of the fabric loading / unloading hatch 10 is connected to the end of the fabric W. The fabrics W are joined to form a loop, and the magnetic body M is attached to the joined portion. Thereafter, if the entire fabric W is fed into the cloth circulation circuit C, the loop-shaped fabric W is circulated through the cloth circulation circuit C while being conveyed by the treatment liquid flow, and the cloth W is subjected to liquid treatment (dyeing treatment). It is done.
[0017]
Thus, in the multi-tank type liquid flow treatment machine of this embodiment, the cloth circulation circuit C through which the cloth W circulates includes two treatment tanks 1 and 1 and two transfer pipes 2 and 2 that are alternately connected. Therefore, every time the cloth W circulates through the cloth circulation circuit C, the cloth W has two relaxing liquid baths in the expanded state by the treatment tank 1 and two times by the transfer pipe 2. The liquid flow conveyance in the rope state is repeated alternately. Therefore, even if the circulation speed of the fabric W is increased and the retention time of the fabric in each treatment tank 1 is not shortened, a uniform liquid treatment that does not cause dyeing spots can be performed.
[0018]
In other words, in the conventional textile processing industry, the improvement of the liquid dyeing machine has been repeated on the assumption that the relaxation liquid bath is performed in one treatment tank for one loop-shaped fabric, and the fabric can be circulated at high speed. However, in this embodiment, the relaxation liquid bath is divided into two treatment tanks 1 and 2 for one loop-shaped fabric W in two. Therefore, even if the amount of the processing liquid is increased to improve the liquid processing capacity, it is not necessary to increase the circulation speed of the fabric, and uniform liquid processing can be performed without damaging the fabric.
[0019]
In addition, the multi-tank liquid flow treatment machine of the present embodiment can be simply configured by simply changing the piping of each transfer pipe of two conventional single-tank liquid flow treatment machines. There is also an advantage that existing facilities can be used effectively.
[0020]
The embodiment which is a specific example of the present invention is generally configured as described above, but the present invention is not limited to this embodiment, and various modifications can be made within the scope of the claims. is there.
[0021]
For example, in the above-described embodiment, two processing tanks 1 and 1 are arranged in parallel in the same plane in the left and right directions in the same direction, and these two processing tanks 1 and 1 are crossed with each other. The cloth circulation circuit C having an approximately 8-character shape is formed by communicating with each other, but the present invention is not limited to this. For example, as shown in FIG. 1, 1... May be communicated by three or more transfer pipes 2, 2... To form one cloth circulation circuit C. In the double tank type liquid flow treatment machine shown in FIG. 2, the liquid flow pump 3, the conduit 31 , and the supply pipe 32 are not shown for the sake of simplicity . Various design changes can be made in consideration of the total amount of processing solution required.
[0022]
【The invention's effect】
As described above, according to the embodiment, in the present invention, the cloth circulation circuit in which the cloth circulates is an endless cloth circulation from a plurality of treatment tanks alternately connected to each other and a plurality of transfer pipes crossed in an approximately eight shape. Since the pipe line is formed, every time the cloth circulates through the cloth circulation circuit, the cloth passes alternately through the plurality of treatment tanks and the plurality of transfer pipes in order. On the other hand, the relaxation liquid bath can be applied in a plurality of times by a plurality of treatment tanks. Therefore, even if the amount of the treatment liquid is increased in order to improve the liquid treatment capacity, it is not necessary to increase the circulation speed of the fabric, and uniform liquid treatment can be performed without damaging the fabric.
[0023]
According to the second aspect of the present invention, as described in the paragraph [0015], the auxiliary reel capable of adjusting the rotation speed changes the fabric from the relaxed liquid bath state to the rapid flow state. The damage of the fabric can be alleviated, and it is possible to assist the pulling up when the fabric is pulled up from the relaxing liquid bath, and the liquid flow treatment can be performed smoothly.
