Abstract

A method of preparing compounds comprising a plurality of components, the method comprising providing a modular dye meter, introducing component into one or more than one modular batching member of the modular dye meter, where the compound to be prepared comprises the one or more than one component, activating the internal rotor of one or more than one of the batching and delivering devices, thereby causing the internal rotors to rotate in the first direction, where rotation of the internal rotor moves component through the progressive recesses of the batching and delivering device through the corresponding delivery duct and through the dispenser, and thereby into a vessel for containing the compound, causing the rotation of the internal rotor in the first direction to cease, causing the internal rotor to rotate in a second direction, where the second direction is opposite to the first direction, thereby moving component back through the delivery duct into the corresponding batching and delivering device, and causing the rotation of the internal rotor in the second direction to cease.

Claims

1. A modular dye meter comprising:

a) one or more than one modular batching member, where each modular batching member comprises a container for storing a component of a compound and comprises a batching and delivering device for moving the component stored in the container, the batching and delivering device comprising a second fluid connecting means and a second electric connecting means;

b) a dispenser comprising a delivery head equipped with a plurality of delivery nozzles;

c) a delivery duct corresponding to each batching and delivering device, and connecting each batching and delivering device to the dispenser, each delivery duct being able to be disconnected from the modular batching member; and

d) a supporting structure equipped with a plurality of seats, each seat being adapted to operatively house one modular batching member and comprising a first fluid connecting means for an operative connection to the second fluid connecting means and a first electric connecting means for an operative connection to the second electric connecting means, the first electric connecting means being quick-connection electric connectors or pins;

where each batching and delivering device comprises a pump comprising an inlet end connected to the container, and comprises an outlet end connected to the delivery duct;

where each modular batching member is connected to one of the plurality of seats by a mechanical connector;

where each pump comprises an external stator housing and an internal rotor within the external stator;

where the internal rotor has an axis of rotation, and where the internal rotor is capable of rotating in a first direction around the axis of rotation, and is capable of rotating in a second direction that is around the axis of rotation, where the first direction is opposite of the second direction;

where each external stator housing comprises progressive recesses and each internal rotor is shaped as a worm screw and comprises progressive recesses; and

where rotation of the internal rotor relative to the external stator housing moves component inside the pump through the progressive recesses and toward the delivery duct corresponding to the batching and delivering device and therefore toward the dispenser when the internal rotor rotates in the first direction, or away from the delivery duct of the corresponding batching and delivering device and therefore toward the container when the internal rotor rotates in the second direction.

2. The modular dye meter of claim 1, where the container for storing one component of the compound comprises a tank.

3. The modular dye meter of claim 1, where the container for storing one component of the compound comprises a stirring blade driven by an actuating motor.

4. The modular dye meter of claim 1, further comprising managing means for controlling the modular batching members.

5. A dye metering machine comprising the modular dye meter of claim 1.

6. The dye metering machine of claim 5, where the dye metering machine comprises a containing structure;

where the containing structure comprises removable coating panels, of the modular dye meter; and

where the containing structure further comprises a height-adjustable plate for supporting at least one vessel under the dispenser.
