Optimizing Rigid Container Handling & Filling With Depalletizers

Optimizing Rigid Plastic Container Handling and Filling with Depalletizers

Plastic container manufacturers, known as blow molding suppliers, play a pivotal role in the packaging industry by supplying containers to countless businesses that package products in rigid plastic containers. From juice, to vitamins, to lotions, to automotive oils and beyond, the extent of the blow molder’s connection to the supply chain cannot be overstated. Additionally, how these blow molding facilities prepare these containers for use varies greatly; some containers are meticulously arranged on pallets, while others are packaged in boxes, requiring unscrambling upon arrival.

As businesses grapple with the diverse challenges posed by incoming containers – whether they arrive loose in boxes or bags, neatly stacked on pallets, or in constantly changing configurations – the choice of container handling approach becomes paramount. When it comes to optimizing the packaging of rigid plastic containers, depalletizers are the unsung heroes, capable of significantly enhancing the process. 

A depalletizer, as the name suggests, efficiently unloads containers from neatly stacked pallets. It takes charge of the initial stages of the packaging process by swiftly sweeping off rows of containers from pallets, ensuring a streamlined and efficient workflow. Depalletizers are the ideal choice for businesses that receive containers organized on pallets, providing a seamless transition from storage to production.

On the other hand, unscramblers specialize in sorting and orienting plastic containers that arrive in bulk. Unscramblers excel at handling the complex task of organizing containers that arrive in random orientations and configurations, ensuring a smooth transition into the production process.

Whether you choose to use a depalletizer alone or pair it with an unscrambler for your line, these machines offer a versatile solution to address various container handling challenges.

Depalletizers on the Line: Enhancing Production

The introduction of depalletizers to a production line offers the potential to boost overall throughput and uptime, providing a valuable asset for businesses. This flexibility is especially advantageous for companies uncertain about receiving plastic containers either palletized or boxed. Let’s delve into the advantages of utilizing depalletizers both independently and in conjunction with unscramblers with specific packaging topics in mind.

Efficiency and Space Optimization

Efficiency and space optimization are critical concerns in every operation. Depalletizers excel at both. They streamline the initial stages of packaging, ensuring a smooth transition from storage to production. Their space-efficient design allows them to operate within confined areas, making them suitable for facilities with limited space or where other equipment and processes exist. When combined with unscramblers, this efficiency extends to handling containers in diverse packaging.

Automation and Labor Efficiency

Automation is a driving force for efficiency in container handling. Depalletizers automate pallet unloading, reducing labor costs and minimizing the risk of human error. When utilized in tandem with unscramblers, this efficient use of labor resources contributes to cost savings and enhanced worker safety, freeing up skilled workers for more critical tasks within the production process. Many types of palletized containers do not need to be pushed into an unscrambler; these containers can be swept directly off of the depalletizer and onto the line to be filled.  For some containers where depalletizing a pallet makes sense prior to filling because of container geometry or other considerations, a bottle chute provides a means to provide a tapered transition from discharge height to the customer’s unscrambler.

Container Changeovers

Flexibility is crucial, especially when handling containers of varying sizes and shapes. Depalletizers simplify changeovers, allowing quick adaptation to different container specifications. This enhances production flexibility, minimizes downtime, and ensures a smooth transition between container types. The combination of depalletizers with unscramblers adds an extra layer of adaptability if one type of container arrives in bags and then next on a pallet.  

If a facility needs to switch between palletized plastic containers of different dimensions, the FHA 3000 Depalletizer, has 20 programmable “menu” presets. With one press of a button you can switch between container sizes, allowing for longer production runs without extensive downtime between container sizes.

Hygiene and Contamination Control

Industries with strict hygiene standards, such as food or pharmaceuticals, prioritize container cleanliness. Depalletizers help maintain container integrity before they enter the production line, particularly for palletized containers, by eliminating manual operator handling that can result in fingers being placed inside of containers When fed directly into a depalletizer, pallets of wrapped containers enter a controlled environment in which the containers move right into a rinse or ionized air system to be cleaned, and then are filled is a system that can reduce the overall risk of contamination.  

Freight and Storage Optimization

Depending on the specific design and geometry of containers, densely packaging them on a pallet can minimize wasted space and lead to more efficient storage and shipping. This high-density configuration directly translates to reduced shipping costs, as it allows for the transportation of more products in a single shipment. Additionally, it maximizes the utilization of available warehouse space, enabling the safe storage of a greater number of containers within a given storage area. This optimization in both shipping and warehousing contributes significantly to cost savings and operational efficiency, regardless of whether unscramblers are part of the configuration.

Container Integrity and Contamination Control

Leaking product, either through a damaged container body or a deformed cap/neck assembly, can result in costly cleanups and delays. Protecting plastic containers in shipping is a key driver for palletizing containers so they do not shift or damage neighboring containers in transit. Leaky containers can not only increase customer complaints, but also cause costly clean-ups and maintenance to the automated equipment in the packaging line.

Ensuring product integrity and minimizing the risk of contamination are benefits consistent in both depalletizer-only and depalletizer-unscrambler setups.
