Positioning Arm for Lid Handling Systems

Product Specifications

Technical details and manufacturing context for Positioning Arm

Definition

The Positioning Arm is a critical component of the Lid Positioning & Feeding Mechanism, responsible for accurately grasping, transporting, and placing lids onto containers or workstations. It ensures precise alignment and controlled movement during the lid handling process. The arm is typically actuated by pneumatic, servo, or stepper motor systems, receiving positional commands from a control system to execute its tasks. It extends, retracts, or rotates to pick up a lid from a feeder or stack, moves along a programmed path, and precisely places the lid at the target location before returning to its home position. Constructed from aluminum alloy (6061-T6, anodized) or stainless steel, the arm is designed for durability and precision in industrial environments. Key parameters include an operating pressure of 1.0–1.6 MPa, a stroke length of 50–200 mm, positioning accuracy of ±0.05 mm, load capacity of 5–20 kg, operating temperature of -10 to 60 °C, cycle rate of 30–60 cycles/min, supply voltage of 24 V DC (±10%), power consumption ≤50 W, protection rating IP54–IP65 (IEC 60529), weight of 3–8 kg, and a mounting interface per ISO 9409-1-50-4-M6. These values are reference ranges and must be verified for the specific model and application. The arm is intended for use in automated lid handling systems, where precise positioning is essential. It is not a standalone product but a component that integrates with a control system and other mechanical parts. For procurement, verify that the arm meets the required specifications and standards for your specific application. Regular maintenance includes checking for wear, ensuring proper lubrication, and verifying alignment. Failure to operate within specified parameters may lead to reduced accuracy or mechanical failure. Always consult the manufacturer for detailed technical documentation and installation guidelines.

Working Principle

The Positioning Arm operates through a combination of actuation and control. It receives positional commands from a control system, which triggers pneumatic, servo, or stepper motors to move the arm. The arm extends, retracts, or rotates to grasp a lid from a feeder or stack, then moves along a programmed path to the target location. Sensors provide feedback to ensure precise placement. After placing the lid, the arm returns to its home position. The movement is controlled to achieve the required positioning accuracy of ±0.05 mm, with a cycle rate of 30–60 cycles/min. The arm's operation is dependent on the supply voltage (24 V DC) and operating pressure (1.0–1.6 MPa) for pneumatic versions. The control system must be properly programmed to ensure smooth and accurate motion.

Frequently Asked Questions

What is the typical operating pressure for the positioning arm?

The operating pressure is listed as 1.0–1.6 MPa. However, this is a reference range; the exact requirement depends on the specific model and application. Always verify with the manufacturer.

Can the positioning arm handle different lid sizes?

The arm has a stroke length of 50–200 mm and a load capacity of 5–20 kg, which can accommodate various lid sizes within these ranges. Customization may be possible, but confirm with the supplier for your specific needs.

What materials are used in the construction?

The arm is available in aluminum alloy (6061-T6, anodized) or stainless steel. The material choice affects weight and corrosion resistance. Verify the material grade with the manufacturer for your application.

What is the positioning accuracy of the arm?

The positioning accuracy is ±0.05 mm, which ensures precise placement. This is a reference value; actual performance may vary based on installation and maintenance. Confirm with the manufacturer for your specific setup.
