Depalletizing System With Vision - Midwest Engineered Systems

The Challenge

Midwest Engineered Systems was challenged to design and build a fully automated robotic depalletizing cell for boxed spray heads that reduces need for human operators while increasing throughput.

 The Requirements

  • Automation System must supply parts to two (2) lines
  • Convey full or partial pallet loads to the depalletizing robot
  • Dynamically pick full boxes from pallets
  • Automatically cut top of box tape
  • Empty box contents into production line feed hoppers
  • Break down corrugated boxes for reuse
  • Automatically stack pallets and send out full stacks for pickup

The Solution

  • The following methods, components and technologies were implemented and integrated to provide a comprehensive solution:
  • MWES developed a custom, compliant end-of-robotic-arm tool with integrated robotic vision system to recognize individual shipping boxes and their configuration
  • The automation system can also dynamically detect partial pallets and various pallet patterns using integrated robotic vision
  • Custom integrated chain driven live roller (CDLR) conveyor system
  • Dynamic box pallet picking and orientation was achieved using robotic automation system combined with machine vision
  • MWES developed a custom box tape cutting system that could be integrated into the automated production system
  • Custom corrugated box breakdown and stacking machine was designed to facilitate reuse of packaging materials
  • Integrated pallet handling with MWES Model PS1200 pallet stacking machine

Impact to the Customer

The MWES developed and installed automated production system offered a number of benefits to the customer that had a large impact on overall production efficiency including:

  • The applied robotic integration achieves a depalletize rate of 1 box every 30 seconds
  • The Robotic depalletizer feeds two bottling lines
  • Complete “lights out” automation system operation requiring far less operations staff
  • Used boxes are broken down and stacked for reuse, supporting customer’s Green manufacturing initiatives
