Gantry Robotic Arm

TheGantry Robotic Armt is an automated loading and unloading system made for a single CNC machine. It combines automatic storage, picking, loading, unloading, and machine connection. With a multi-layer storage magazine and a gantry three-axis system, it can run a single machine for long hours without any operator.

This system uses one gantry robot dedicated to one CNC machine. This one-to-one mode has clear advantages: simple motion logic, no machine conflicts, and no need for material splitting. The machine and robot signals are deeply connected. Door opening, clamping, processing, and unloading are all in one closed loop. Response is fast and coordination is precise.

Zhejiang Luban has many years of experience with gantry robots. Our one-to-one series is widely used for batch processing of shafts, discs, flanges, and precision hardware parts. We have successful cases from single-machine automation to multi-machine linked production.

For a single CNC machine, the most important thing is stability and simplicity. The system does not need complex functions. But it must be reliable – no frequent alarms, no constant adjustments.

TheGantry Robotic Armt is made for this need. It serves only one machine. The motion logic is simple. There is no coordination problem with other machines. The robot knows exactly when the machine opens its door, when to clamp, and when to process. There is no timing conflict or waiting. One customer told us that after using this unit, their single machine's operation rate went from 65% to over 85%. Because the system is stable and needs almost no manual help, one worker can watch several machines at the same time.

The gantry robot uses three-axis servo coordination – X-axis for horizontal travel, Y-axis for front-back movement, and Z-axis for reach. It takes parts from the multi-layer magazine and moves to the machine door to wait. When the machine finishes and opens the door, the robot removes the finished part and loads the new one. Then it returns to standby.

The multi-layer magazine uses 5 to 10 layers. Each tray feeds independently. When a layer is empty, the system switches to the next one. This gives long continuous feeding. Workers can reload empty layers while the machine runs. No need to stop. The control uses a Delta gantry system with a 7-inch touch screen teach pendant. The system connects to the machine through standard signals. It supports automatic picking, empty alarm, and fault stop.

The body uses a heavy steel structure. It is rigid and does not deform easily. The three axes use precision linear guides with servo motors. Running is stable and repeat positioning is accurate. Speed can be adjusted to match the part and machine cycle. The multi-layer magazine uses a modular design. Layer spacing can be adjusted for different part sizes. The tray repeat positioning accuracy is within ±0.25 mm. The working temperature range is -10°C to 45°C. Safety features include a fence, emergency stop, sound and light alarms, and motion interlocks with the machine. During automatic operation, the robot cannot hit the machine door, parts, or fixtures. If there is a problem, it stops and alarms immediately.
