Solution for Lifting and Moving Sheet Metal Blanks for Laser Cutting Machines

During sheet metal processing with a laser cutting machine, lifting and moving metal sheets from the pallet to the machine table is a process that requires significant manual labor, precision, and safety. For materials with large dimensions or heavy weight, manual handling is not only difficult but also increases the risk of collisions, scratches, and safety hazards.

Vietmani provides Industrial Manipulators and Vacuum Lifters with suitable fixture options, helping you lift, move, and position metal sheets more gently and accurately. Depending on the material, dimensions, weight of the workpiece, and production process, Vietmani can advise on a solution suited to the actual needs of the factory.

Requirements for sheet lifting equipment for laser cutting machines

To lift and move metal sheets safely, the equipment must not only meet the load capacity but also suit the material characteristics, workpiece dimensions, and machine layout in the workshop. When choosing a solution, you should consider several important factors below:

Lifting capacity

• First, it is necessary to accurately determine the maximum weight of the workpiece to be lifted, while also taking into account the weight of the fixture. Choosing equipment with an appropriate load capacity ensures a stable lifting process and guarantees safety during operation.

Dimensions and shape of the workpiece

• Metal sheets can come in various sizes, thicknesses, and shapes. Large but thin sheets are often prone to bending when lifted, so the equipment and fixtures need to be designed to distribute the load-holding force appropriately.

Material surface characteristics

• For Vacuum Lifters, the surface condition of the workpiece is a factor that must be checked before selection. Flatness, roughness, oil, or dust on the surface can affect the ability to create and maintain a vacuum.

Movement requirements

• Depending on the production process, the equipment may need to perform multiple operations such as lifting, lowering, lateral moving, or rotating the workpiece. Therefore, it is essential to clearly determine the stroke and movement direction from the pallet to the machine table to select the suitable configuration.

Safety and workpiece protection

• Besides load lifting capacity, the equipment must help operators control the workpiece well during movement, limiting collisions and reducing the risk of scratching the material surface. This is also a crucial factor when handling workpieces with high requirements for surface quality.

Based on factors such as load capacity, workpiece dimensions, material, operation frequency, and actual layout, Vietmani advises on Industrial Manipulators, Vacuum Lifters, and suitable fixture options for each application.

• Reduce manual labor: Minimizes manual lifting of workpieces.
• Protect surfaces: Reduces direct contact and friction with the workpiece, limiting the risk of scratching.
• Flexibility for various workpieces: Suction units can be designed to match the dimensions and characteristics of the material.
• Increase operational safety: Helps operators gain better control over the workpiece during lifting and moving.

With vacuum lifting solutions designed for each application, Vietmani helps you optimize the picking – moving – positioning stages for laser cutting machines, especially for workpieces with surfaces suitable for vacuum suction technology.

Case Study: Lifting sheet metal from pallet to laser cutting machine

The real-world problem

During workpiece preparation for a laser cutting machine, picking large steel plates from the pallet and placing them on the machine table requires precise lifting, moving, and positioning operations. If done manually, this process can be exhausting, difficult in controlling the load, and carries hidden safety risks.

In addition, the steel plate needs to be kept stable during movement to limit shifting or dropping of the load.

VIETMANI's Solution

Vietmani implemented an Industrial Manipulator combined with a pneumatic vacuum suction fixture cluster specifically designed for steel plates.

The fixture cluster uses suction pads spread across the surface, helping to distribute the holding force and increase stability when lifting steel plates. The equipment is simultaneously equipped with safety mechanisms to control the load and limit the risk of dropping the workpiece during movement.

How the solution works

The operation process is carried out simply:

Approach workpiece → Activate suction pads → Check load-holding condition → Lift workpiece → Move → Position on machine table → Release workpiece

The suction pads contact the workpiece surface and create a suction force to hold the steel plate. Once the load-holding condition is ensured, the operator uses the Industrial Manipulator to lift and move the workpiece to the required position.

Throughout the operation, safety mechanisms assist in controlling the load-holding status, contributing to minimizing the risk of dropping the workpiece during movement.

Effectiveness of the solution

The solution helps optimize the lifting and feeding process for the laser cutting machine:

• Reduce manual labor: Operators do not have to directly lift heavy steel plates.
• Hold workpiece securely: The distributed suction pad system helps keep the steel plate stable.
• Increase flexibility: The Industrial Manipulator supports convenient lifting, moving, and positioning of the workpiece.
• Enhance safety: Safety mechanisms help control the load and limit the risk of dropping the workpiece during operation.
• Optimize feeding process: Assists in moving workpieces from the pallet to the machine table faster and more conveniently.

This is an example showing that an Industrial Manipulator is not just lifting equipment, but can be combined by VIETMANI with specialized fixture clusters to specifically solve each workpiece lifting and moving problem in the factory.
