摘要:
Systems and methods for in-line inspection of plastic blow molded containers. The inspection system may comprise a plurality of emitter assemblies arranged in a vertical array. Each emitter assembly may cyclically emit light energy in at least two different narrow wavelength bands at a container as the container passes through an inspection area. The system may also comprise a plurality of broadband photodetectors arranged in a vertical array, each photodetector facing at least one of the emitter assemblies with the inspection area therebetween such that the photodetectors are capable of sensing light energy that passes through the container when it is in the inspection area. The system may also comprise a processor in communication with the photodetectors for determining a characteristic of the container based on signals from the photodetectors.

Various embodiments are directed to systems and methods for measuring a thickness of a container. For example, a control device may receive data indicating a surface topology of the container and based on the surface topology of the container, instruct a multi-axis positioning system to position a sensor relative to a first point of the container such that: a distance from the sensor to a surface at the first point is about equal to a predetermined distance; and the sensor direction is about normal to the surface at the first point. Data indicating the thickness at the first point may be received from the sensor.
摘要:
A system and a method for controlling a container manufacturing machine include a thickness monitor (10) for determining an average wall thickness of containers produced by the machine. The system uses the average wall thickness to adjust machine control to change operation of the machine and adjust the quality of the containers being produced. The system also responds to feedback from pneumatic devices (104), heaters (103), mechanical devices and temperature sensors (108, 109) to determine corrections to be made to the machine operation.
