Panel Turnover Frame Auxiliary

1. Definition

A panel turnover frame (panel flipper / inverter auxiliary) is material-handling equipment that rotates flat sheets or formed panels — commonly about 90° or 180° — so the opposite face can be processed, inspected, stacked, or packed without manual crane flipping.

It is an auxiliary device beside roll-forming or fabrication cells. Internal evidence is photo / video level; public capacity, cycle time, and power remain blocked.

2. Role in a plant

• Between cutting / forming and double-sided finishing
• Ahead of inspection when both faces must be checked
• Inline with roller conveyors, stackers, or robotic load/unload
• Beside press-brake or panel cells where heavy sheets are unsafe to flip by hand

Industry panel flippers emphasize clamping or vacuum hold-down, protective padding for coated sheets, and interlocking so a power loss does not drop the load.

3. Typical motion

1. Panel enters on conveyor or is placed on the flipper table
2. Clamps / vacuum secure the workpiece
3. Frame rotates to the programmed angle
4. Release and exit to the next conveyor or station

Drive may be hydraulic, pneumatic, or electromechanical depending on mass and duty. Exact drive package follows the proposal.

4. Parameter status

5. Boundaries

• Not a roll-forming host
• Not a press brake or shear
• Not a full robotic palletizing cell (may interface with one)
• Not interchangeable with coil tippers / upenders without checking load geometry

6. Inquiry checklist

• Max panel length × width × thickness and weight
• Coated / painted surface protection needs
• Required flip angle (90° / 180°)
• Infeed / outfeed conveyor height and line speed interface
• Safety package (light curtains, self-lock, e-stop layout)

7. Buyer FAQ

Can you publish a standard kW / tonnage?

No. Capacity is panel-specific. Send size and weight so engineering can size the frame.

Will it match my roof-panel line speed?

The flipper is an auxiliary with its own cycle. Do not assume the host’s m/min rating transfers.

Is this the same as a stacker?

No. Stackers accumulate finished parts; turnover frames change orientation. Some projects buy both.

Why is this in the roll-forming encyclopedia?

Because many panel plants inquire for it next to forming lines. Treat it as auxiliary handling, not as a forming mill.
