Abstract

A workstation for cutting glass into panes includes a personal computer having a board for receiving signals from a transmitter and a video board for controlling a second display in addition to and independently of a first display. The first display is for quantitative data concerning the cut pattern, e.g. the dimension of a cut, and the second display is for qualitative data concerning the cut pattern, e.g. a graphic image illustrating the cut. The worker signals the computer by means of the transmitter to indicate that a cut has been completed. The cut pattern is displayed as a series of individual cuts. Only after the worker has signaled that a cut is completed does the computer display the next cut.

Claims

1. A process for providing computer assistance to a person at a manual workstation for manufacturing goods, the process comprising the steps of:

a) defining a task for the manufacture of the goods and storing data representative of the task in the memory of the computer as task data;

b) displaying the task data on a video monitor for viewing by the person by;

(i) separating the task data into qualitative data and quantitative data;

(ii) displaying the qualitative data on a first video monitor; and

(iii) displaying the quantitative data on a second video monitor;

c) awaiting an input from the person to the computer indicating that the task was completed; and

d) after the input is received, either returning to step a) or terminating the process.

2. The process as set forth in claim 1 wherein the computer includes a keyboard and said step of awaiting an input includes the step of:

interrupting said process when a predetermined key in the keyboard is actuated.

3. A process for providing computer assistance to a person at a manual workstation for manufacturing goods, the process comprising the steps of:

a) defining a task for the manufacture of the goods and storing data representative of the task in the memory of the computer as task data;

b) evaluating the subjective preferences of the person at the manual workstation, wherein the preferences are stored as preference data in the memory of the computer;

c) optimizing the task data for the person at the manual workstation;

d) displaying the task data on a video monitor for viewing by the person;

e) awaiting an input from the person to the computer indicating that the task was completed; and

f) after the input is received, either returning to step a) or terminating the process.

4. A computer assisted, manual workstation comprising:

a computer including a microprocessor, memory, a first video monitor and a second video monitor, and I/O circuitry;

at least one tool for use in the manufacture of goods;

said computer being programmed

(a) to display a task to be executed by a person using said tool as quantitative information on said first video monitor and as qualitative information on said second video monitor; and

(b) to wait for a response from said person through said I/O circuitry indicating that the task was correctly executed, whereupon the computer displays the next task for the person.

5. The computer assisted, manual workstation as set forth in claim 4 and further comprising a transmitter remote from said computer for sending a signal from said person to the I/O circuitry of said computer.

6. The computer assisted, manual workstation as set forth in claim 5 wherein said transmitter is portable and is carried on said person.

7. A process for providing computer assistance to a person at a manual workstation for cutting glass, said process comprising the steps of:

defining a cut pattern in which the desired panes optimally fit a sheet from which the panes will be cut and storing said cut pattern in the memory of a computer;

defining a cut sequence for said cut pattern by comparing said cut pattern with predetermined criteria stored in the memory of said computer;

causing said computer to re-define said cut pattern if said criteria are not met, else displaying a cut from said cut pattern on at least one video monitor for said person to see;

causing said computer to wait for a signal from said person, said signal indicating that the cut has been completed;

displaying the next task in said cut sequence when said signal is received.

8. The process as set forth in claim 7 wherein said cut pattern is re-defined after each cut.

9. The process as set forth in claim 7 wherein said displaying steps each include the steps of:

displaying the cut qualitatively on a first video monitor; and

displaying the cut quantitatively on a second video monitor.

10. The process as set forth in claim 9 wherein the cut is displayed qualitatively as a graphic image including an image of said sheet and an image of the cut pattern.

11. The process as set forth in claim 10 wherein said cut pattern is displayed qualitatively by displaying visually distinct panes, cutoffs, and scrap.

12. The process as set forth in claim 7 and further including the steps of:

storing data representative of stock inventory, data representative of cutoff inventory, and data representative of product inventory in said computer; and

revising said data representative of stock inventory, data representative of cutoff inventory, and data representative of product inventory when said signal is received.

13. The process as set forth in claim 12 and further including the step of;

displaying a unique storage location for a pane as each pane is completed, wherein the storage location for each pane is determined in accordance with an operation subsequent to cutting.
