A CLEVER new trimmer switch which easily distinguishes between different work pieces has been released by SMC Pneumatics .
The D-RPK can be set to perform tasks based on three different user-determined parameters.
For example, it will detect whether a workpiece is small, medium, large - or non-existent - and then signal for it to be diverted, sorted or stacked depending on the size detected. The switch can detect differences as small as 0.5mm between work pieces.
The D-RPK is also able to judge the height of a work piece or confirm that other manufacturing operations have been performed for quality control purposes.
For example, it can detect that a hole has been drilled to the correct depth in a workpiece and reject it if it is not to specification.
Such functions are of particular importance in sorting applications or in quality control work where pieces may be rejected from final process or packaging based on their size or weight.
Simply mounted onto a standard cylinder either directly or through the use of a mounting rail, the new D-RPK is ideal for use in a variety of manufacturing operations including product transfer, quality control, gauging, assembly or stacking.
A two-colour LED screen enables operators to see at a glance how a piece has been grouped according to its size or weight.
Each of the two trimmers on the unit is easily adjusted for fast changes of detection parameters but is secure enough to ensure that settings can not be changed inadvertently.
