Stopper Cylinders and Feed Separators

Festo Stopper Cylinders and Feed Separators

Festo’s stopper cylinders and feed separators are essential components for controlled part flow in automated systems. They are designed to stop, accumulate, position, or release workpieces traveling along conveyors or feeding tracks. These cylinders withstand high impact loads, offer precise stopping actions, and ensure smooth, repeatable material flow in production environments.

The product range includes pneumatic stopper cylinders, shock-absorbing versions, and feed separating mechanisms that release items individually or in timed intervals—perfect for high-speed assembly, packaging, and handling lines.

⭐ Important: These actuators are built for high-impact durability, precise part control, and smooth separation of fast-moving workpieces, making them indispensable in conveyor-based automation.

Design & Functionality

• Stopper cylinders extend a robust plunger or stop gate that halts moving parts on a conveyor or indexing track.
• Available damping types include:
  • Elastic cushioning for lighter loads
  • Hydraulic shock absorbers for high-impact conditions
  • Metallic/rigid stop designs where maximum strength is required
• Feed separator models use a controlled lifting or blocking mechanism to release products one at a time, preventing jams and ensuring proper spacing.
• Integrated position sensing options allow real-time monitoring of stop or release position.
• Heavy-duty housings and reinforced shafts ensure long-term reliability even under repeated impact cycles.

⭐ Important: Shock-absorber variants dramatically reduce mechanical wear and allow high-speed stopping without damaging workpieces or equipment.

Total Crossed Beams

(Interpreted as complete control across the workflow)

• Ensures full-cycle control over stopping, blocking, buffering, and separation tasks.
• Maintains stable motion flow and prevents workpiece collisions or misalignment.
• Guarantees consistent performance even in continuous-duty automated lines.

Beam Pitch Options

(Translated as load ranges, stroke options, and force variants)

• Multiple stroke lengths are available to suit different conveyor heights and stop-point requirements.
• Versions designed for light, medium, and heavy loads.
• Optional reinforced designs for very high stopping forces and harsh industrial environments.
• Feed separators feature different lifting heights and timing configurations depending on part geometry and flow rate.

⭐ Important: The wide choice of stroke, load capacity and damping types makes these cylinders ideal for customized conveyor automation.

Intrinsic Synchronism

• Piston and stop gate movement is precisely synchronized for repeatable stop positions.
• Damping systems ensure smooth motion, preventing part bounce or rebound.
• Feed separators maintain consistent, isolated part release with each pneumatic actuation.

Operational Advantages

• High impact resistance for demanding conveyor applications
• Smooth part flow through effective stopping and release strategies
• Protective damping systems to reduce shock forces
• Compact designs to fit standardized conveyor layouts
• Suitable for high-speed automation thanks to fast response times
• Applications: Intralogistics, packaging lines, material feeding systems, palletizing, assembly stations, automated conveyors, accumulation lines.
