25kg Payload 1500mm Reach Collaborative Robot Palletizing Cell for Carton Stacking

Overview

This cobot palletizing cell is built on the Elite Robots CS625, the highest payload model in the CS series: 25kg payload, a 1500mm working radius and 0.08mm accuracy in a 58kg arm with a 240mm footprint. One 1500mm reach covers a pallet position, the conveyor infeed and a buffer stack, so a single cell replaces the manual lift-and-place step at the end of a packing line. Because the arm weighs only 58kg, the same collaborative robot palletizing cell can be moved to a second line on a pallet truck.

The 25kg payload matches a carton, tote or crate of up to 25kg together with a vacuum or finger gripper, which is the normal weight band on food, e-commerce and household goods lines. Cycle speed is supported by joint speeds of 125 to 210 degrees per second and a typical TCP speed of 2.0 m/s, so a 25kg payload 1500mm reach cobot keeps pace with a case packer running at moderate output. Where a line runs two shifts a day, that 25kg payload 1500mm reach balance removes the need for a second cell.

Accuracy of ±0.08 mm on a 25kg payload 1500mm reach cell is more than a carton placement task needs, and that margin is the point: the cell can also place interlayer sheets, slip sheets and label-side alignment without adding a second machine. Because the arm is a collaborative robot certified to ISO 10218-1, ISO/TS 15066 and ISO 13849, the guarding concept can often be reduced after a risk assessment instead of a fixed fence on every side. For a cobot palletizing cell this is the main cost saving, because fencing, gates and interlocks shrink with the arm.

Environment is handled by IP65 protection as standard with IP68 optional, an operating range of -10 °C to 50 °C, noise below 70 dB and cleanroom class 5 compliance to ISO 14644. That combination makes this collaborative robot suitable for chilled packing halls, dusty flour and feed bagging areas, and electronics cleanrooms where a standard industrial arm needs a cover. The cobot palletizing cell can be mounted at any angle, so the arm can sit on a pedestal, hang from a frame over the pallet build zone, or stand beside an existing conveyor.

Programming this collaborative robot is by free-drag teach, the graphical interface or Python script, and offline programming is supported for new pallet patterns. A 625W typical power draw keeps running cost low, and the standard controller (IP44, 15kg) or OEM controller (IP40, 7.5kg) both provide 24 DI/24 DO with 8 safety-configurable channels, 2 AI, 2 AO and RS485, Modbus TCP/RTU, Ethernet/IP slave and Profinet slave connectivity.

Key Specifications

Advantages

• A 25kg payload 1500mm reach cobot covers one pallet build position plus conveyor infeed from a single base position.
• 58kg arm weight and a Ø 240 mm footprint let the cell be bolted to a standard pallet frame or a movable trolley base.
• IP65 standard protection, IP68 optional, lets the collaborative robot work in wash-down halls, flour dust and chilled rooms from -10 °C.
• Cleanroom class 5 and SEMI-S2 compliance allow the same cobot palletizing cell in electronics and medical packaging areas.
• Free-drag teaching and Python scripting cut changeover time on the cobot palletizing cell when a new carton size reaches the line.
• Any-angle mounting supports overhead or wall-mounted layouts, so the collaborative robot can hang directly over the pallet build zone.
• 625W typical power draw keeps running cost far below a traditional 4-axis palletizer.
• Open fieldbus stack lets the cobot palletizing cell talk to existing PLC, conveyor and labelling equipment.

Applications

• Carton and case palletizing on a cobot palletizing cell at the end of food and household goods packing lines
• Tote and tray handling in e-commerce and distribution buffers
• Bag-in-box and sack palletizing in flour, feed and chemical plants
• Cleanroom palletizing of electronics trays and medical device packs
• Mixed SKU pallet builds with interlayer sheet placement
• Overhead or wall-mounted palletizing where floor space is limited

Frequently Asked Questions

Q: Why choose a 25kg payload 1500mm reach cobot for palletizing instead of a 4-axis palletizer?
A: A collaborative robot palletizing cell fits where a conventional palletizer cannot: low volume, mixed carton sizes, frequent pattern changes and limited floor space. The 25kg payload covers most case-packed goods, and the 1500mm reach covers a pallet plus infeed without a second machine.

Q: Does a collaborative robot remove the need for guarding?
A: No. Safety is still based on a risk assessment of the complete cell, including gripper, carton weight and approach speed. For a 25kg payload 1500mm reach cobot, gripper design and approach speed drive the assessment most. Compliance to ISO 10218-1, ISO/TS 15066 and ISO 13849 allows a reduced guarding concept in many layouts, and we confirm the final concept for your site.

Q: How fast can this palletizing cell run?
A: Joint speeds reach 210°/s on J4-J6 with a typical TCP speed of 2.0 m/s, and on a 1500mm reach cell the cycle time is dominated by travel between conveyor and pallet. Real throughput depends on carton weight, pattern and travel distance; for a 10 kg carton and a single pallet position, share your target rate and we will confirm cycle time.

Q: Can it work in a cold room or a dusty plant?
A: This collaborative robot is rated IP65 standard with IP68 optional and operates from -10 °C to 50 °C at humidity below 90%. That covers chilled packing halls and dusty areas such as flour or feed bagging.

Q: Is a cleanroom version available?
A: Yes. The CS625 is certified to ISO 14644 cleanroom class 5 and SEMI-S2, so the same cobot palletizing cell can be installed in electronics and medical packaging cleanrooms.

Q: How is the cell programmed for a new carton size?
A: Through free-drag teaching, the graphical interface or Python script, with offline programming for new pallet patterns. On the cobot palletizing cell a new pattern typically needs only a few waypoints and a sheet drop position.

Q: What is the lead time and shipping format?
A: Stock arms ship within 7 working days; cell builds with gripper and frame take 20 to 35 days. Each cobot palletizing cell ships in an export wooden crate with shock-proof foam and sea-worthy bracing.
