Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for charging powder into a dye liquor blending machine and a powder charging device used in this method.

[Prior Art] The dye liquid supplied to a dyeing machine such as a continuous pad dyeing machine is prepared using dyes of various colors, dyeing aids, and water as raw materials. As the dye, sometimes a liquid dye is used, and sometimes a powder dye is used. As for dyeing aids such as surfactants and finishing pastes, liquid urea, starch paste, succinol, sodium alginate, etc., and powdered sodium chloride, soda ash, etc. are used.

Regarding the liquids prepared in each specialized tank, that is, liquid dye, liquid auxiliary agent, and water, for example,
As shown in Japanese Patent No. 12386, a dispenser having a cylinder and a piston can be controlled by a microcomputer to automatically feed a predetermined amount to a liquid preparation tank.

However, for powder dyes and powder auxiliaries, it has been difficult to automate powder handling, so conventionally,
After feeding the liquid into the liquid preparation tank, the only option was to manually add the weighed powder directly into the container.

[Problems to be Solved by the Invention] In the conventional method of adding powder dyes and powder auxiliary agents as described above, the powder to be added was placed directly into the container, so the powder in the container was subject to moisture absorption. There was a problem of deterioration or scattering resulting in contamination of other powders to be measured or contamination of the surrounding environment.

In addition, human errors such as adding the wrong powder or forgetting to add the powder occurred, and the desired dye solution could not be obtained. If dyeing is performed without obtaining the desired dye solution in this manner, it becomes necessary to dye the fabric or the like again after dyeing has been completed, resulting in a decrease in the efficiency of the dyeing process.

SUMMARY OF THE INVENTION An object of the present invention is to provide a method for introducing powder into a dye liquor mixer that solves the above problems by automating the introduction of powder necessary for dyeing, and a powder introduction device used in this method.

[Means for Solving the Problems] In order to achieve the above-mentioned object, the method for introducing powder into a dye liquor blending machine according to the present invention includes packaging the powder with a water-soluble film 79 and transporting the powder into a transport container 78. The conveying container 78 is placed on the belt conveyor 76 in the order of dye solution preparation and conveyed, and then the conveying container 78 is held and tilted to convey the powder packaged with the aqueous solution film 79. The liquids are sequentially poured into the liquid preparation tank 2.

Further, the powder feeding device of the dye liquor blending machine according to the present invention includes a belt conveyor 76 on which transport containers 78 containing powder wrapped in a water-soluble film 79 are placed in the order of dye liquor blending, and A dropping means 80 holds the transport container 78 transported by the transport container 76 and tilts the transport container 78 to drop the powder wrapped in the water-soluble film 79 and the liquid preparation tank 2 one after another.
The dropping means 80 has a bucket 108 whose one end is pivotally supported on a horizontal axis, and a bucket 108 in which the transport containers 78 conveyed by the belt conveyor 76 are sequentially loaded onto the bucket 10.
8, a pusher 116 for holding the transport container 78 by holding it therein, and a drive means for rotating the bucket 108 around the horizontal axis by pushing up the lower surface of the bucket 108. 11 were established.

In order to introduce powder into a designated one of the plurality of liquid preparation tanks 2, a bucket 1 is supported on a turntable 102 rotatable around a vertical axis and a bucket 1 is placed on a horizontal axis.
The driving means 118 can be constituted by an air cylinder, one end of which is pivotally supported on the lower surface of the bucket 108, and the other end of which is supported by the turntable 102.

[Function] The transport containers 78 containing the powder packaged with the water-soluble film 79 are placed on the belt conveyor 76 in the order of dye solution preparation. At this time, the water-soluble film 79
prevents powder scattering, moisture absorption and foreign matter contamination. The dropping means 80 tilts the transport container 78 transported by the belt conveyor 76 while holding it, and sequentially throws the powder wrapped in the water-soluble film 79 into the liquid preparation tank 2 as it is. The water-soluble film 79 dissolves in the liquid preparation tank 2, making it possible to dissolve the powder. Furthermore, even if the water-soluble film is torn during transportation, the leaked powder can be caught in the transportation container, so the conveyor will not be contaminated.

A conveyor 92 constituting the dropping means 80 is used to transport containers 78 transported by the belt conveyor 76.

The powder feeding device 24 includes a belt conveyor 76 and a dropping device 80.

On the belt conveyor 76, plastic tray-shaped transport containers 78 containing weighed powder dyes wrapped in a water-soluble film 79 made of PVA, for example, are placed in the order of dye solution preparation. The transport containers 78 are sequentially transported to the locations where the two liquid preparation tanks 2a and 2b are provided.

Reference numeral 92 denotes another conveyor disposed above and perpendicularly to the belt conveyor 76 and supported by columns 94. A transfer lever 96 is provided on the lower surface of the conveyor 92 and projects downward. The transport container 78 containing the powder dye is moved to just below the conveyor 92. The transfer lever 96 is movable back and forth along the conveyor 92 as well as vertically, and sequentially transfers the transfer containers 78 to the bucket 108 . However, in FIG. 1, the conveyor 92 is drawn with a two-dot chain line.

The guide 98 extends along the conveyor 92 at the same height as the top surface of the belt conveyor 76 to guide the liquid preparation tanks 2a, 2b.
It stretches towards. The tip of the guide 98 is in contact with a side surface of a circular top plate 104 of a cylindrical turntable 102 that is rotatably supported around a vertical axis on a base 100 . The liquid preparation tanks 2a, 2b, which are cylindrical containers, and the turntable 102 have a common plane passing through their center line, and are arranged so that this common plane is perpendicular to the direction in which the conveyor 92 is disposed. However, the top plate 104 of the turntable 102 is positioned higher than the upper ends of the liquid preparation tanks 2a and 2b. An oval opening 106 is formed approximately in the center of the top plate 104.

A bucket 108 is arranged on the upper surface of the top plate 104 so as to close the opening 106. Bucket 108
has a bottom plate and three U-shaped side plates, and two side plates 109 parallel to the direction in which the conveyor 92 is disposed have protrusions 110 formed toward the front, respectively. A horizontal shaft 114 passes through the protrusion 110, and both ends of the horizontal shaft 114 are connected to the turntable 102.
Support piece 1 provided upward on top plate 104 of
It is supported by 12. A pusher 116 is provided on one of the two side plates 109, and the transport container 78 can be held between the pusher 116 and the other side plate 109 facing the pusher 116.

Reference numeral 118 denotes an air cylinder disposed inside the cylindrical turntable 102, which drives the rotation of the bucket 108 about the horizontal axis 114. The tip of the piston rod of the air cylinder 118 is rotatably supported by a shaft 122 on a support piece 120 formed downward on the bottom plate of the bucket 108, and the other end of the air cylinder 118 is
It is rotatably supported by a support piece 124 provided on the inner surface of the turntable 102 with a shaft 126 . Note that the turntable 102 has 2 liquid preparation tanks 2
128 in either the left or right direction so that the powder dye can be poured into the specified one of a and 2b.
130 can also be rotated 90 degrees around the vertical axis.

The powder feeding device 24 described above is controlled by a computer (not shown). This computer is
Considering that two large and small liquid preparation tanks 2a and 2b are provided, the order of dye liquid preparation is determined along with the liquid preparation tanks to be used so that liquid preparation can be carried out most efficiently.

The worker wraps the weighed powder dye in a water-soluble film 79 and transfers it to the transport container 7 in the order of dye liquid preparation.
Place it on 8. Due to packaging, powder dyes scatter,
Moisture absorption and foreign matter contamination are prevented.

The belt conveyor 76 transports the transport container 78 loaded with the powder dye to a position where the dropping means 80 is provided. After supplying the hot water and liquid auxiliary agent to the liquid preparation tank 2a or 2b, the dropping means 80 is
is driven, and the powder dye placed in the transport container 78 is put into the selected liquid preparation tanks 2a, 2b in the following manner.

The transport container 78 containing the powder dye and moved to just below the conveyor 92 is pushed by the transport lever 96, passes over the guide 98, and is transported onto the bottom plate of the bucket 108. Thereafter, the transfer lever 96 is raised to the position shown by the two-dot chain line in FIG. Next, the pusher 116 operates to hold the transport container 78 in the bucket 108. After this holding, the turntable 102 is rotated 90 degrees in the right direction 128 around the vertical axis when the powder dye is to be put into the liquid preparation tank 2a, and to the left when the powder dye is to be put into the other liquid preparation tank 2b. Rotate 90 degrees to 130. After the turntable 102 is rotated, the piston rod of the air cylinder 118 is extended as shown in FIG. When this angle of inclination exceeds a certain value, the powdered dye held in the transport container 78 falls into the designated liquid preparation tank while being wrapped in the water-soluble film 79.

After this input, the turntable 102 and the air cylinder 118 are returned to their original positions, and the pusher 11
6 is released to free the transport container 78. Then, after the transfer lever 96 moves forward by a certain distance, it descends and reaches the inside of the empty transfer container 78.
This transport container 78 is pulled back onto the belt conveyor 76 by retraction. Then, the empty transport container 78 is transported by the belt conveyor 76 toward the weighing position, and the transport container 78 containing the powder dye to be added next is moved to just below the conveyor 92. Note that the film 79 in the liquid preparation tanks 2a and 2b dissolves in water, and the powder dye dissolves in the liquid.

[Effects of the Invention] In the present invention, since the powder in the transport container 78 is packaged with the water-soluble film 79, moisture absorption and scattering of the powder can be prevented. Moreover, this packaging
Since it is composed of a water-soluble film 79, it dissolves in the liquid preparation tank 2 and does not interfere with the dissolution of the powder in this tank.

In addition, by simply placing the conveyor container 78 containing the powder packaged with the water-soluble film 79 on the belt conveyor 76 in the order of dye liquid preparation, the belt conveyor 76 can
The powder is conveyed by the drop means 80, and the powder is sequentially thrown into the liquid preparation tank 2 by the dropping means 80, so it is possible to prevent the wrong powder from being thrown in or forgetting to put it into the dyeing process. can improve work efficiency. Moreover, the powder packaged with the water-soluble film 79 can be thrown into the liquid preparation tank 2 without coming into contact with it.

Furthermore, even if the film is torn during conveyance, the leaked powder is caught by the conveyor container, so the conveyor will not be contaminated, and cleaning can be done by just using the conveyor container, and there is no need to clean the conveyor.

Further, if the transport container 78 is transferred to the bucket 108 by the conveyor 92 and the lower surface of the bucket 108 is pushed up and tilted by the driving means 118, the powder wrapped in the water-soluble film 79 is transferred into the liquid preparation tank 2. Fall easily.
