Patent ES-389392-A1 (ES)
Title: Impact simulator method and apparatus
IPC: G01N3/00
Filed: 1971-03-20
Abstract: The testing of glass containers for structural defects, principally in the side wall surfaces thereof, is provided wherein bottles are conveyed in succession at spaced-apart intervals through the testing device. The testing device takes the form of a wheel having a substantial thickness mounted to rotate about a vertical axis, with the periphery of the wheel extending over a portion of the width of the conveyor belt. A pressure plate having a vertical surface facing in the direction of the wheel and positioned and supported from the opposite side of the conveyor has a surface configuration closely paralleling that of the curvature of the wheel. The pressure plate and wheel are positioned relative to each other such that a container, in order to pass between the wheel and the pressure plate, is subjected to a lateral compressive force. Because of the contour of the wheel and length of the pressure plate, at least 180 DEG of the bottle circumference finds itself being compressed by the wheel during the precessing motion of the container through the testing device. The force applied by the wheel to the bottle or container is applied by a fluid motor whose output piston acts upon the movable axis of the wheel to bias the wheel in the direction of the pressure plate. Thus it can be seen that every container may be physically stressed and if a defective bottle is present, it will be broken by the compressive force. Both the wheel and pressure plate bottle-engaging surfaces are lined with a plastic material having the characteristic that it does not readily retain glass fragments.
