Abstract

An automatic dissolving device for dyes or the like according to the present invention comprises:

(1) an electromagnetic valve situated midway in a pipeline from a medium or stock solution tank to a dissolving or mixing vessel,

(2) a turntable with a number of holes around the circumference to accept a number of dissolving or mixing vessels,

(3) an electronic type balance below the turntable to weigh the dissolving or mixing vessels and one or more magnet-type stirring devices arranged below the turntable so as to stir the solution in the dissolving or mixing vessel, and

(4) a mathematical operation control device, so as to enable the solution of dyes or the like accurately and automatically and under a sufficiently stirred state without requiring much time and skill.

Claims

1. An automatic dissolving device comprising:

at least one tank for receiving a liquid,

a turntable containing a plurality of holes disposed along the circumference thereof;

a plurality of vessels, each arranged in the holes for receiving a material to be mixed,

a pipeline connected at one end to the tank for discharging said liquid therefrom, and at the other end to said plurality of vessels for transferring said liquid discharged from the tank through said pipeline to said vessels,

an electromagnetic valve disposed on the pipeline,

an electronic type balancing means arranged at a first predetermined position and below a passageway through which the holes pass in rotation of the turntable for weighing a tare of the vessel to thereby deliver a first signal indicating the tare and for weighing the vessel in which the material is received to thereby deliver a second signal corresponding to the weight of the material,

rotating means connected to the turntable for rotating the turntable,

a magnet-type stirring device arranged below the passageway and at a second predetermined position to perform the mixing of the material with the liquid by rotating a magnet disposed in the vessel by magnetic force through the bottom wall of the vessel, and

a control device for delivering respectively, third and fourth signals at the first predetermined position and a third predetermined position to the rotating means to rotate the turntable to thereby move the vessel from the first predetermined position to the third position and from the third position to the second position;

means for determining the weight of the material as such received in the vessel based on the first and second signals;

means for delivering a fifth signal to the electromagnetic valve to open the valve for a time interval determined from the thus determined weight when the vessel reaches the third predetermined position, and

means for delivering a sixth signal to the magnet-type stirring device to operate the magnet-type stirring device when the vessel reaches the second predetermined position.

2. The device according to claim 1 wherein a plurality of the tanks are provided together with a corresponding number of pipelines and electromagnetic valves.

3. The device according to claim 1 wherein the tank is provided with an immersing type electrical heater for maintaining the temperature of the liquid constant, a thermostat for controlling the temperature, and a blade-type stirring device for stirring the liquid.

4. The device according to claim 1 wherein the turntable is fixed, but means are provided for moving the electronic type balance and the magnet-type stirring device in the vertical direction.

5. The device according to claim 1 wherein the electronic type balance and the magnet-type stirring device are fixed, and means are provided for moving the turntable in the vertical direction.

6. The device according to claim 1, which further comprises air supplying means for accelerating the flow of the liquid through the electromagnetic valve by adding air pressure to the inside of the tank, and a magnet-type stirring device for stirring the liquid in the tank.

7. The device according to claim 1 which further comprises a pan for holding the vessel so that a rotating magnet of the magnet-type stirring device can be situated just below the vessel.

8. The device according to claim 1, in which a plurality of the magnet-type stirring devices are arranged with equal angular distance from each other below the passageway defined by a one-half rotation of the turntable from the second predetermined position.
