[0002] In the machinery industry, a loading mechanism is required to transport workpieces to designated workstations for production or cleaning. The commonly used loading mechanisms on the market are generally chain conveyors combined with robotic arms to transport workpieces. However, this loading method is suitable for bulk workpieces.

After the chain conveyor mechanism transports the workpieces into place, the robotic arm grabs the workpieces and transfers them to the designated workstations for subsequent processing. However, some workpieces are stacked together on pallets. If a chain conveyor mechanism is used, the workpieces need to be removed from the pallet and then placed.

[0023] During use, the gap loading mechanism for stacking workpieces described in the present invention is used in conjunction with a robotic arm, and the two are controlled by the same central control device.
