Abstract
The present system provides a means to record an image of an item which is extremely difficult to inspect because of its peculiar shape or because the person who is inspecting it cannot come in close proximity thereto, such as red hot glass being measured for form and size immediately upon being formed into a bottle. The present system employs a television camera and logic circuitry to electronically compare the profile of said image against a standard item whereby the item being inspected or measured can either be rejected or accepted.
Claims10
A system for monitoring three dimensions of an item which is being fabricated and which has an irregular shape including a plurality of critical width dimensions and critical length dimensions and requiring a particular depth characteristic and which item is initially difficult to physically inspect comprising in combination:
- means to effect an image of said item which image can be seen and recorded by a TV camera means;
- TV camera means disposed to see and temporarily record each of said item images whereby each of said item images can be scanned to translate said recorded images into electronic signals related thereto;
- first electronic circuitry means connected to said TV camera means to receive said electronic signals and in response thereto to generate first signals representing different width dimensions of said item image;
- second electronic circuitry means connected to said TV camera means to receive said electronic signals and in response thereto to generate second signals representing different lengths of said item image;
- third electronic circuitry means connected to receive said first and second signals and to perform arithmetic operations thereon to generate third signals representing said particular depth characteristic and to generate fourth signals representing critical width dimensions of said item and to generate fifth signals representing critical length dimensions of said item;
- fourth electronic circuitry means into which electronic signals can be stored to represent a standard item image, said fourth electronic circuitry means being formed to provide sixth signals representing critical width dimensions and critical length dimensions of said standard item image;
- fifth electronic circuitry means connected to said third and fourth electronic circuitry to monitor said particular depth characteristic signal for detection of an error thereof and to compare said fourth and fifth signals with said sixth signals to detect an error therebetween, whereby said item is either rejected or accepted as an approved item.
