180kg Payload 3195mm Reach 5-Axis Palletizing Robot Arm High-Speed Robotic Palletizer

The KR 180 R3200-2 PA is a five-axis palletizing robot arm purpose-built for end-of-line stacking, depalletizing and layer forming. A rated payload of 180 kg and a maximum reach of 3195 mm let one palletizing robot arm cover a full pallet plus the infeed conveyor, so bag, carton and pail lines run without an intermediate transfer station.

The PA kinematic layout deliberately omits a fourth axis. That saves one gear unit and one servo drive, shortens the moving mass and gives the arm the stiff, upright posture that stacked loads demand. Pose repeatability of plus/minus 0.07 mm to ISO 9283 keeps layer patterns square even after a full shift of high-speed cycles.

Quality control follows the load path. The 754 mm x 754 mm base casting and the arm sections are machined in a single setup, gear units are matched to the measured backlash of each axis, and the assembled arm is laser-tracked for alignment before sealing. Every 180kg payload 3195mm reach unit then completes a 72-hour continuous motion test at rated payload, and the torque, temperature and repeatability curves are shipped as its test report against the published technical data.

Energy use is part of the specification rather than an afterthought. Five axes mean five drives to feed instead of six, which lowers standby and partial-load consumption on multi-shift palletizing lines. Powder coating is low-VOC, gear units are sealed for life so lubricant is neither topped up nor disposed of in normal service, and energy-optimised motion profiles flatten the current peaks drawn during high-inertia layer moves.

Stability comes from the structure and from the palletizing software stack. A wide cast base resists the reaction torque of a 180 kg load swinging at 3195 mm, and IP65 protection on both arm and wrist keeps dust from cardboard, flour or cement out of the joints. The KR C5-2 or KR C5 controller contributes integrated safety functions, open fieldbus interfaces, remote diagnostics and ready-made palletizing technology packages with pattern generators.

• 180kg payload at rated duty, expandable to 230 kg, covers bag, carton, pail and drum formats.
• 3195mm reach serves a full pallet and its infeed conveyor from one floor position.
• Five-axis PA kinematics on this palletizing robot arm remove one drive and one gear unit.
• Plus/minus 0.07 mm repeatability keeps stack layers aligned through a full shift.
• IP65 protection on arm and wrist tolerates dusty carton, flour and cement environments.
• 754 mm x 754 mm footprint fits inside existing end-of-line layouts without civil work.
• Palletizing technology packages generate patterns without custom robot programming.
• Five drives instead of six reduce standby power on multi-shift palletizing lines.

• Bag, carton and pail palletizing at end-of-line stations
• Depalletizing and layer forming before stretch wrapping
• Beverage and food case stacking on high-speed lines
• Building material and cement bag stacking cells
• Drum and pail handling in chemical filling plants
• Truck loading and warehouse transfer of unit loads

• Why does this palletizing robot arm use five axes instead of six?
  Palletizing needs position and orientation about a vertical axis, not a fourth wrist rotation. Dropping that axis removes a gear unit and a servo drive, reduces moving mass and lowers cost while keeping the 180kg payload 3195mm reach envelope operators actually use.
• What load can the arm stack in continuous duty?
  It is rated at 180 kg continuous duty at the flange, with up to 230 kg available when load centre distances are short and supplementary loads stay inside the published limits. Gripper weight and centre of gravity are checked against the payload diagram before the cell is fixed.
• How far can one robot reach in a palletizing cell?
  The maximum reach is 3195 mm, which normally covers a pallet position plus the infeed conveyor, so no linear track is needed and the layout keeps its transfer points to a minimum.
• What does IP65 mean in a dusty plant?
  IP65 seals the arm and the wrist against dust ingress and water jets, which covers carton dust, cement powder, flour and routine wash-down around the 180kg payload 3195mm reach palletizing station.
• How is stacking accuracy maintained at speed?
  Pose repeatability is plus/minus 0.07 mm to ISO 9283 with rated payload, and the palletizing packages compensate pattern offsets in the controller, so layer alignment holds while axis speeds reach 321 degrees per second on A6.
• How is the unit shipped and supported?
  Each arm ships on a wooden pallet case with shock-proof foam, desiccant and export strapping, together with axis data and test reports. Commissioning guidance, spare gear units and servo parts are available after delivery.

Share the product format, layer pattern, stack height and cycle target, and our engineers will confirm whether the 180kg payload 3195mm reach palletizing robot arm fits the line, together with gripper interface, safety layout and delivery schedule.
