About electric palletizer

Types of electric palletizers

Generally speaking, an electric palletizer is a machine used to stack products on pallets automatically. In this way, the electric palletizer allows the automatic construction of piles of products on pallets or other bases, which are then used for the correct distribution of the products. Electric palletizers are one of the most crucial machines in the food, beverage, and pharmaceutical industries. An electric palletizer is the ideal machine to facilitate the stacking process in these industries.

According to the arrangement method, supply turret direction, and number of tiers forming/transfer method, there are several electric palletizer types.

Automatic Stack Cubing is one of the most popular types of electric palletizers. In Auto Stack Cubers, products are arranged into pre-defined patterns before being pushed onto a pallet. This method is effective for handling cartoned products, bags, and cases, among others.

Robotic Palletizers are another popular automatic palletizing system. These involve a robotic arm that picks up products and stacks them onto a pallet. They are flexible and can handle different product shapes and sizes.

In-line Palletiser Machines are automatic machines that stack cartons on pallets. They are commonly used in large-scale production facilities to streamline packaging and distribution processes. The automatic in-line palletizer works in conjunction with other automated systems to create a completely automated packaging and palletizing solution.

The floor> means that the entry point for goods to be stored will be at ground level. A floor entry palletizer will allow operator access at the same level. Tiered exit refers to a system where pallets of goods are unloaded vertically in a tiered fashion. Electric palletizers with a tiered exit will have up-speed conveyors that will release pallets of goods at a higher speed. A tiered entrance will also have in-conveyors that will be at a lower speed to receive the goods.

Seq/reen exit means the sequential and reverse exit of pallets. Robots are ideal for this kind of work as they can be programmed to release pallets of goods sequentially or in reverse order. Moreover, a drop/ grab means that the robot will drop or pick up goods from a particular location.

Floor Entry is another important electric palletizer type. It means that the entry point for goods to be stored will be at ground level. A floor entry palletizer will allow operator access at the same level.

Un-cornered pallets are also an important consideration when buying an electric palletizer. Some pallets are cornered, i.e., the corners are removed and formed into a square or rectangular shape. For example, in a grocery store, a partial pallet of products may be placed around the four corners of the pallet. This is ideal when there is limited space, and goods are placed on the shelves in a grocery store.

Specification and maintenance of electric palletizers

Specifications

  • Product size

    Common sizes for electric palletizers:

    Low-level: approximately 1,200 mm x 1,200 mm x 1,500 mm

    Mid-level: around 1,800 mm x 1,500 mm x 4,000 mm

    High-level: roughly 2,500 mm x 2,000 mm x 5,000 mm

  • Production capacity:

    The automated palletizer speeds up packing. It replaces manual work, saving time.
    Low-speed palletizers handle 300 to 600 cases per hour. Mid-speed ones do 600 to 1,200. High-speed palletizers work faster than 1,200 cases each hour.

  • Pallet type and size

    Electric palletizers work with many pallet kinds:

    Wood: Common sizes are 40 x 48 inches in North America and 1,200 x 1,000 mm in Europe.

    Plastic: Similar dimensions to wood pallets. Some have adjustable parts to change sizes.

    Metal: Frequently used in large industries. Normal measurements are 40 x 48 inches or 1,200 x 1,000 mm.

  • Machine weight

    Heavy-duty electric palletizers for big production may weigh over 7,000 kg. Lighter models used in small places might weigh around 3,000 kg.

Maintenance

  • Daily:

    Turn on the electric palletizer and check for part wear, damage, or loose components. Inspect and clean safety devices, sensors, and photoelectric switches. Verify pallet destination correctness and that the stacking pattern is accurate. Maintain adequate lubrication levels for moving parts.

  • Weekly:

    Check that electrical connections show no signs of wear or looseness. Ensure the compressed air system functions adequately by inspecting hoses, fittings, and connections for leaks.

  • Monthly:

    Examine fork assemblies and pallet pushers for damage and proper alignment. Clean the photoelectric sensors with a soft cloth. Conduct a thorough inspection of safety guards and covers to ensure they remain in place and undamaged.

  • Quarterly:

    Grease the pallet drops and other sliding parts according to the manufacturer's specifications. Verify that the limit switches are calibrated correctly and adjust them if necessary. Check the condition of the fuses and replace them if necessary.

Scenarios of electric palletizers

The usage scenarios for electric palletizers are many. The main one is in the logistics industry in all its branches. From supplying goods, and food and beverage products, to pharmaceuticals, cosmetics, and brewery industries, among others, electric palletizers stand as the backbone of efficient operations.

Modern production lines in various industries rely heavily on electric palletizers. Automation is key, and electric palletizers offer that, increasing the efficiency of how products are stacked.

Distribution centers and warehouses are constantly looking for ways to optimize space. An electric palletizer is the perfect machine to efficiently help stack goods and hence save space. It also makes it easy to retrieve stacked goods.

The retail industry makes a lot of use of palletizers. Products need to be stacked neatly in retail stores to optimize space and make goods easy to find and retrieve. Electric palletizers do this job easily and quickly.

Heavy industries that deal with big crates and boxes make use of automatic electric palletizers. These machines eliminate the need for manual work and ensure that stacking is done uniformly and perfectly. Automatic electric palletizers are highly efficient and can stack products with high volume.

Shipping and transportation industries deal with the heavy-duty requirement of stacking goods and pallets properly. Electric palletizers are the best solution for ensuring that goods are safely and securely stacked before being transported.

Small- and medium-sized businesses also use electric palletizers. While they may not be on a large scale, these businesses still require efficient and automated stacking solutions to help their goods be easily retrieved and stacked safely.

How to choose electric palletizers

Several factors should be considered when selecting an electric palletizer for a specific application.

  • Assess workload and dimensioning

    First, it's essential to identify workload characteristics such as pallet sizes, products that need to be handled, and quantities. This can help one understand the workloads and dimensions that the electric palletizer will handle. The workload assessment helps determine the capacities, dimensions, and design of the electric palletizer that meets specific needs.

  • Consider product-specific requirements

    Second, one should consider special product requirements. For instance, if one is handling fragile items, one's electric palletizer should have features that prevent product damage. Also, products with different shapes and sizes may require special handling attachments or procedures.

  • Consider integration with existing systems

    Third, the selected electric palletizer should have the ability to integrate with other existing systems, such as conveyors and sorting systems. Good integration can lead to a more fluid production line and workflow.

  • Consider safety and ergonomics

    Electric palletizers are designed with safety features, such as emergency stop buttons and protective covers, to ensure operator safety. Additionally, ergonomic design concepts should be considered to reduce manual handling and enhance operator comfort.

  • Consider maintenance and support services

    It's crucial to choose an electric palletizer with an adequate maintenance support network. The supplier should provide timely maintenance and repair services. Additionally, the supplier should provide technical support and spare parts to ensure the proper operation of the electric palletizer.
