Pouch Filling System using UR3 & OnRobot RG2

Industry > Food·DrinkApplication > Packing·PackagingSector > Manufacturing

This application case features an automated grain filling process utilizing two Universal Robots UR3 units and OnRobot RG2 grippers. By positioning the compact UR3 robots on both sides of a pouch feeder, the system efficiently handles picking and opening pouches. The wide-stroke RG2 grippers allow for rapid and precise manipulation of flexible packaging, ensuring a streamlined flow from feeding to grain dispensing.

Components

Robot	Robot: Universal Robots UR3 (2 Units) Type: 6-axis articulated collaborative robot Payload: 3kg Reach: 500mm (Horizontal) Weight: 11.2kg Repeatability: ±0.1mm (Standard UR3 spec; provided as 0.3mm) Protection Rating: IP54 Gripper: OnRobot RG2 Feature: Wide-stroke collaborative gripper optimized for picking and holding flexible pouches.

Workflow

STEP 1.	Feeding: Pouches are supplied through a dedicated feeder.
STEP 2.	Picking: The dual UR3 robots pick up the pouches using RG2 grippers.
STEP 3.	Filling: Grain is accurately dispensed into the opened pouches.
STEP 4.	Discharge: The filled pouches are moved onto a conveyor for the next process.

Key Features

Maximize Space Utilization with Compact Cobots

Small Footprint: Utilizes 3kg-class compact collaborative robots (UR3) to minimize process layout changes, allowing for installation in confined or narrow spaces.

Increased Productivity with Multi-Purpose Grippers

Integrated Handling: Combines long-stroke scissor-type grippers (RG2) with vacuum grippers to simultaneously perform pouch picking and opening.
Minimized Downtime: Optimized gripper configurations reduce idle time during process transitions.

Implementation Results

ROI Period	2 years
Key Metrics	Reduction in labor required for repetitive manual tasks. Increased productivity through continuous production with minimized idle time.
Client Feedback	Productivity has significantly increased thanks to the robot's ability to perform continuous, uninterrupted operations.
