Palletizer using robotics

A palletizer or palletiser is a machine which provides automatic means for stacking cases of goods or products onto a pallet.

Contents

Manually placing boxes on pallets can be time consuming and expensive; it can also put unusual stress on workers. [1] The first mechanized palletizer was designed, built, and installed in 1948 by a company formerly known as Lamson Corp.

There are specific types of palletizers including the row-forming which were introduced in the early 1950s. In row-forming palletizing applications loads are arranged on a row forming area and then moved onto a different area where layer forming takes place. This process repeats until a full layer of goods and products are configured to be placed on a pallet.

The in-line palletizer was developed in the 1970s when higher speeds were needed for palletizing. This palletizer type utilizes a continuous motion flow divider that guides the goods into the desired area on the layer forming platform.

Robotic palletizers were introduced in the early 1980s and have an end of arm tool (end effector) to grab the product from a conveyor or layer table and position it onto a pallet. [2] Both conventional and robotic palletizers can receive product at a high elevation, typically 7–10.33 feet (2.13–3.15 m), or low "floor level" elevation of 2.5–3.0 feet (0.76–0.91 m). The end of arm tooling has evolved in recent years to accommodate a variation of pack pattern and package types.

Mixed case palletizing

Mixed case palletizing is a real-world application variant of the 3D Bin packing problem, where the goal is to stack mixed size cases onto a pallet in such a way it optimizes the space utilization i.e., stack as many cases onto a minimum amount of pallets. Although widespread applications in logistics exist, it remains a challenging problem, and stacking of mixed size products still largely involves manual labour.

Mixed case palletizing is subject to additional challenges as it not only requires robotics to grab the oncoming item i.e., determine the position of the product and robot kinematics to actually pick it up, but also to determine the size and optimal placement position on the pallet. [3] In recent years, some research has utilized Deep Reinforcement Learning, where robotic agents aim to learn an optimal placement position by stacking many pallets in simulation. Some works apply there learned model in real-world environments. [4]

In transportation, freight refers to goods conveyed by land, water or air, while cargo refers specifically to freight when conveyed via water or air. In economics, freight refers to goods transported at a freight rate for commercial gain. The term cargo is also used in case of goods in the cold-chain, because the perishable inventory is always in transit towards a final end-use, even when it is held in cold storage or other similar climate-controlled facilities, including warehouses.

Packaging is the science, art and technology of enclosing or protecting products for distribution, storage, sale, and use. Packaging also refers to the process of designing, evaluating, and producing packages. Packaging can be described as a coordinated system of preparing goods for transport, warehousing, logistics, sale, and end use. Packaging contains, protects, preserves, transports, informs, and sells. In many countries it is fully integrated into government, business, institutional, industrial, and for personal use.

A pallet is a flat transport structure, which supports goods in a stable fashion while being lifted by a forklift, a pallet jack, a front loader, a jacking device, or an erect crane. Many pallets can handle a load of 1,000 kg (2,200 lb). While most pallets are wooden, pallets can also be made of plastic, metal, paper, and recycled materials.

<span class="mw-page-title-main">Distribution center</span> Building stocked with goods for delivery

A distribution center for a set of products is a warehouse or other specialized building, often with refrigeration or air conditioning, which is stocked with products (goods) to be redistributed to retailers, to wholesalers, or directly to consumers. A distribution center is a principal part, the order processing element, of the entire order fulfillment process. Distribution centers are usually thought of as being demand driven. A distribution center can also be called a warehouse, a DC, a fulfillment center, a cross-dock facility, a bulk break center, and a package handling center. The name by which the distribution center is known is commonly based on the purpose of the operation. For example, a "retail distribution center" normally distributes goods to retail stores, an "order fulfillment center" commonly distributes goods directly to consumers, and a cross-dock facility stores little or no product but distributes goods to other destinations.

Pallet rack is a material handling storage aid system designed to store materials on pallets. Although there are many varieties of pallet racking, all types allow for the storage of palletized materials in horizontal rows with multiple levels. Forklift trucks are usually required to place the loaded pallets onto the racks for storage. Since the Second World War, pallet racks have become a ubiquitous element of most modern warehouses, manufacturing facilities, retail centers, and other storage and distribution facilities. All types of pallet racking increase storage density of the stored goods. Costs associated with the racking increases with increasing storage density.

<span class="mw-page-title-main">Unit load</span> Size of assemblage into which individual items are combined for ease of storage & handling

The term unit load refers to the size of an assemblage into which a number of individual items are combined for ease of storage and handling, for example a pallet load represents a unit load which can be moved easily with a pallet jack or forklift truck, or a container load represents a unit for shipping purposes. A unit load can be packed tightly into a warehouse rack, intermodal container, truck or boxcars, yet can be easily broken apart at a distribution point, usually a distribution center, wholesaler, or retail store for sale to consumers or for use.

A shipping container is a container with strength suitable to withstand shipment, storage, and handling. Shipping containers range from large reusable steel boxes used for intermodal shipments to the ubiquitous corrugated boxes. In the context of international shipping trade, "container" or "shipping container" is virtually synonymous with "intermodal freight container", a container designed to be moved from one mode of transport to another without unloading and reloading.
