Petri Dish (Challe) Packaging through Cartesian Robots

Industry > Metal·PlasticsApplication > Packing·PackagingSector > Manufacturing

This is an automated packaging solution that replaces the manual process of stacking and bagging Petri dishes with a system powered by three Cartesian (Gantry) robots.

By utilizing a combination of three Cartesian robots, the system performs continuous operations at high speeds. The linear design of these robots allows for a compact installation, making it ideal for facilities with limited floor space while maintaining high throughput.

Components

Robot	Robot: 3 Cartesian Robots (Multi-Axis Linear Systems) Robot 1: Product infeeding and precision stacking. Robot 2: Packaging material (poly bags/sleeves) feeding. Robot 3: Transferring the stacked products into the packaging unit. Sealing Unit: High-speed thermal or ultrasonic sealer for airtight finishing. Gripper System: Vacuum-based or soft-touch grippers designed to prevent scratches on transparent plastic.

Workflow

STEP 1.	Stacking: Products are stacked to a predefined count.
STEP 2.	Alignment: Ensuring the stack is perfectly vertical and centered.
STEP 3.	Material Infeed: Feeding the packaging film or sleeve.
STEP 4.	Positioning: Moving the product stack to the exact packaging coordinates.
STEP 5.	Opening: Automatically opening the mouth of the packaging material.
STEP 6.	Insertion: Pushing the product stack into the packaging sleeve.
STEP 7.	Sealing: Hermetically sealing the entrance of the package.
STEP 8.	Discharge: Moving the finished package onto the outfeed conveyor.
