System Description

The figure shows a simple sorting system for cubes of different dimensions $.$ Where the

cubes are loaded into the magazine. The decision of the cube size is done via two sensors

S$1$ and S$2$ at the magazine lower part $($just before pushing the box out$).$

The sorting algorithm is as follows;

$$ If S$1$ AND S$2$ detect the cube then it is defined as long length cube as the distance

between the two sensors adjusted equal to the length of the long cube. Cylinder B

$($Normally extended$)$ is retracted to direct the conveyor to position $1.$

$$ If sensor S$1$ only detects the cube, then the system defines it as the small cube, and

it is directed to to position $2.$

Operating Problem

The small cubes should be aligned to the direction of the S$1$ otherwise; no action will be

taken by the sorting station. As the position of the small cube is not guarantee to be

aligned towards S$1,$ it could be slightly moved away towards S$2($other direction$).$

Required

$1.$ Show on the given figure a pneumatic proposal configuration to solve this problem by

using only one pneumatic component to align the small cubes towards S$1.$

$2.$ Draw the Pneumatic circuit for the proposed solution.
