Abstract

A method and apparatus for managing the supply of liquid color to a process machine utilizes an electronic memory device connected permanently to a container of liquid color and an electronic memory controller that interacts with the electronic memory device, preferably wirelessly over the Internet.

Claims

1. ) Apparatus for transport and dispensing liquid color comprising:

a) a container;

b) an electronic memory device connected to the container; and

c) a liquid color pump connected to the container.

2. ) Apparatus of claim 1 wherein the electronic memory device is physically connected to the container.

3. ) Apparatus of claim 2 wherein the electronic memory device is permanently connected to the container.

4. ) Apparatus of claim 1 wherein the electronic memory device is built into the container.

5. ) Apparatus of claim 3 wherein the electronic memory device is selected from the group comprising flash drives, thumb drives, memory chips, and integrated circuit chips.

6. ) The apparatus of claim 1 wherein the electronic memory device comprises a read/write memory.

7. ) A method for furnishing liquid color to a plastic resin process machine to fabricate finished or semi-finished plastic parts of a prescribed color from a liquid color container having an electronic memory, comprising:

a) loading the electronic memory with information relating to the liquid color in the container, the information including the weight of the container when full and when empty, and the pounds per gallon density for the liquid color in the container;

b) metering a predetermined weight of liquid color, on a machine cycle-by-machine cycle basis, from the liquid color container to a process machine;

c) continuously sensing weight of the liquid color container from which the liquid color is being drawn;

d) computing the average loss of weight of liquid color by the container per process machine cycle;

e) adjusting the predetermined weight in step “

b”

on the basis of average loss of weight of the liquid color container for each process machine cycle.

8. ) A method for managing the supply of liquid color to a process machine, comprising:

a) providing a container of liquid color having an electronic device physically connected to the container;

b) loading the electronic device with information relating to liquid color in the container, the information including identification of the color, the quantity of liquid color in the container, weight of the container when empty and when full, and the weight density of the liquid color in pounds per gallon;

c) providing liquid color to a process machine from the container as the process machine produces plastic parts;

d) weighing the container when supply of liquid color to the process machine has concluded;

e) computing the quantity of liquid color consumed by the process machine by subtracting the weight of the container when supply of liquid color has concluded from the container weight stored in the electronic memory device and converting such weight difference to pounds of liquid color consumed.

9. ) The method of claim 8 further comprising prior providing liquid color to the process machine, comparing the identification of color in the electronic device with a preselected color specified for the plastic parts, and rejecting the container if the identification of color in the electronic device differs from the preselected color.

10. ) The method of claim 9 wherein the comparison is performed electronically by the electronic device.

11. ) The method of claim 8 wherein the electronic device comprises an electronic memory and an electronic controller.

12. ) The method of claim 8 further comprising providing the pounds of liquid color consumed information to a central facility computer.

13. ) Apparatus for storage, shipment and dispensing liquid color, comprising:

a) a portable container for liquid color, the container comprising;

(i) an electronic memory device and;

(ii) a liquid color pump connected to the container with at least a portion of the pump being at least partially within the container; and

b) an electronic controller operatively connected to the electronic memory device for reading data, respecting any liquid color in the container, from the electronic memory device and comparing that data to specifications for the liquid color to be dispensed from the container.

14. ) The apparatus of claim 13 wherein the electronic memory device comprises read/write memory.

15. ) The apparatus of claim 13 wherein the electronic controller further reads data from the electronic memory device and dynamically maintains corrected inventory data for the liquid color as the liquid color is consumed from the container by a manufacturing process.

16. ) A method for verifying a shipment of liquid color vis-à

-vis an order for liquid color having specifications therefor, comprising;

a) loading a container with a batch of liquid color of a given hue;

b) downloading information respecting that batch of liquid color into an electronic memory device affixed to the container;

c) reading the information from the electronic memory device;

d) comparing the information read from the electronic memory device with the liquid color specifications and verifying that the liquid color furnished for the order is correct if the information matches the specifications.

17. ) The method of claim 16 wherein the information and the specifications both include hue identification.

18. ) The method of claim 16 wherein the information and specifications both include color number, container contents weight, manufacturer lot number and date of manufacturer of the liquid color.

19. ) The method of claim 16 where in reading is performed using a portable, handheld device.

20. ) The method of claim 16 further comprising:

a) dynamically reading the container contents weight from the electronic memory device;

b) recording the dynamically read container contents weight;

c) computing rate of usage of the liquid color from the dynamically recorded container weights; and

d) adjusting inventory of liquid color containers based on computed rate of liquid color usage.
