Precise counting of falling small parts

The counting unit SPW 40 LI 70 counts and separates small parts up to the dimensions 50 x 50 x 50 mm as the largest component and can detect components of 5 x 5 x 5 mm. A conveyor belt transports the components into the separator. Counting happens via passing through a photocell. The target quantity is a free customer parameter.

The counted components fall into a custom buffer. Two buffers are stored in the unit. When the target quantity of the first buffer reached, the counting unit automatically switches to the second production buffer. The unit displays full Production buffer. A reporting of this message via OPC UA to a higher-level ERP system is possible. Replacing, empty through full buffer, must acknowledged manually.

In case that both production buffers are full an alarm appears. The system switches off and the production machine may stop via alarm signal. If both production buffers are fully switched off the system. The production buffers always contain the correct quantity.

The unit is currently available in two variants:

- for components in the dimensions 5 x 5 x 5 mm up to 50 x 50 x 50 mm

- for components in the dimensions 20 x 20 x 20 mm up to 150 x 150 x 150 mm

Features:

• Separate components 
• Components counting / storing components 
• Variant 1 for components from 5 - 50 mm (H / W / D) 
• Variant 2 for components from 20 - 150 mm (H / W / D) 
• 2 production buffers per unit
• Shutdown by full production buffer 

Custom design – adaptable to virtually any customer specifications.
