What is the Difference Between Truss Destacking Stamping Line and Top Suction Destacking Stamping Line

Automated stamping production lines typically combine a destacking system with a multi-station transfer system, commonly including truss destacking stamping lines and top suction destacking stamping lines. Next, we will explore their differences.

Destacking System

1. Appearance

(Appearance of the truss type and top suction type.)

The truss destacking system adopts an open gantry structure with functional components distributed throughout. The top suction destacking system adopts a modular integrated structure with functional components tightly arranged.

2. Stack Position

(The stack position of the truss type and the top suction type.)

The truss destacking system requires manual installation of positioning rods on the trolley for positioning. The top suction destacking system has positioners on both sides of the trolley, enabling automatic positioning, and is suitable for stacks of various shapes.

3. Magnetic Separation

(The magnetic separation of the truss type and top suction type.)

The magnetic separation device in the truss destacking system requires manual installation and position adjustment. The magnetic separation device in the top suction destacking system automatically adjusts its position and has a parameter memory function, allowing for one-button recall for different products.

4. Sheet Pickup

(The sheet pickup of the truss type and top suction type)

In a truss destacking system, the suction cup positions are fixed and require manual adjustment, with no parameter memory function. In a top-suction destacking system, each suction cup is independent and controlled by its own cylinder. The suction cup positions can be adjusted automatically, and the system includes parameter memory, allowing flexible use for products of different shapes.

5. Sheet Convey



The truss destacking system has only a lower conveyor. The top suction destacking system has both an upper and a lower conveyor.

6. Dual-Sheet Removal

(The dual-sheet removal about the truss destacking system. It can remove dual-sheet.)

The truss destacking system stops and triggers an alarm if double sheets are detected, or a short section of the conveyor belt runs in reverse to eject the sheets. The top suction destacking system has the double-sheet detection device on the upper conveyor. If double sheets are detected, the sheets are directly released into the collection box. If the sheets pass the detection, they continue forward and are released onto the lower conveyor for further transfer.

7. Sheet Position

For different sheet sizes, the truss destacking system requires manual replacement of the appropriate tapping device. The top-suction destacking system has tapping devices installed at different positions on the upper and lower conveyors, allowing it to effectively handle sheets of various sizes.

Multi-Station Transfer System

In a truss destacking stamping transfer system, the main and auxiliary manipulators are installed on the same horizontal plane as the press, resulting in weaker vibration resistance. It uses a gear-and-rack transmission, and the clearance between the gear and the rack requires manual adjustment. In a top suction destacking stamping transfer system, the manipulator uses a box-type structure, which provides higher strength, better rigidity, and stronger vibration resistance. It uses a ball-screw transmission, which offers higher accuracy during repeated movements.

(Here is the box-type structure. The main operating units at the front and rear are installed on different horizontal planes, making the structure more robust and more resistant to vibrations generated by stamping.)
