Abstract
The device automatically clears high elongation test samples with long tails after breakage from a materials testing device after the testing has been performed. A robotic arm engages the tested specimen and brings it to a specimen clearing device which includes a slot leading to a nip between an opposed drive wheel and driven wheel. A motor drives the drive wheel to move the tested specimen through the specimen clearing device into a scrap bin or similar repository.
Claims10
A method for clearing tested samples from a materials testing machine, including the steps of:
- providing an engaging device for engaging materials testing samples in a materials testing machine and transferring the materials testing samples to a sample clearing device, wherein the sample clearing device includes:
- first and second engaging surfaces for engaging the testing sample, wherein the first and second engaging surfaces are respectively a first opposed wheel on a fixed axle and a second opposed wheel on a floating axle biased toward the fixed axle, wherein the floating axle has a first end and a second end, and wherein a nip is formed between the first and second opposed wheels;
- a driver for at least one of the first and second opposed wheels, thereby activating at least one of the first and second opposed wheels and transporting the materials testing sample;
- and
- a housing including an upper opening for receiving the testing sample, a lower opening through which the testing sample is ejected, and first and second side slots through which respective first and second ends of the floating axle extend.

A system including:
- a materials testing machine for performing tests on testing samples;
- a sample clearing device;
- wherein the sample clearing device includes:
- first and second engaging surfaces for engaging the testing sample, wherein the first and second engaging surfaces are respectively a first opposed wheel on a fixed axle and a second opposed wheel on a floating axle biased toward the fixed axle, wherein the floating axle has a first end and a second end, and wherein a nip is formed between the first and second opposed wheels;
- a driver for at least one of the first and second opposed wheels, thereby activating at least one of the first and second opposed wheels and transporting the materials testing sample through the sample clearing device to a repository;
- and
- a housing including an upper opening for receiving the testing sample, a lower opening through which the testing sample is ejected, and first and second side slots through which first and second ends of the floating axle extend.
