The present invention relates generally to systems and methods for securing goods during transportation and storage. More specifically, it pertains to a retrofit system for conventional pallets, incorporating adjustable strapping mechanisms and complementary components to enhance load stability and protection. The invention addresses the need for improved securing solutions for pallets used in various industries, including logistics, warehousing, and shipping, offering adaptable and efficient methods for maintaining the integrity of goods throughout the supply chain.
The present invention relates to methods and systems for securing goods on pallets to ensure stability and protection during transportation and storage. Ensuring that goods remain intact and undamaged during transit is essential for maintaining product quality and customer satisfaction. One widely used method for securing goods on pallets is pallet wrapping, also known as stretch wrapping, which involves enveloping the goods with a stretch film to stabilize and protect them. Pallet wrapping can be conducted manually or with automated machinery, depending on the scale and requirements of the operation.
In addition to pallet wrapping, several other methods are employed to secure goods on pallets. Strapping involves using metal or plastic straps tensioned and sealed with a tool or machine, suitable for heavy loads. Ratchet straps use a ratcheting mechanism for excellent load stability, ideal for heavy or bulky items. Bungee cords provide a flexible and adjustable means of securing lighter loads quickly. Netting and mesh cover and secure goods, offering versatility for various load shapes, while adhesive and non-slip pads increase friction and stability, and corner boards and edge protectors distribute tension and prevent damage.
Specialized pallets with integrated strapping technology have also been developed to enhance load security. These pallets are designed with built-in straps that can be easily adjusted and tensioned, providing a secure hold on the goods without the need for additional wrapping or external strapping tools. The integrated strapping system simplifies the securing process, reduces handling time, and ensures consistent tension across the load. This innovative solution is particularly beneficial for industries requiring quick and reliable palletization, offering a streamlined approach to load stabilization and protection.
Despite the advantages of specialized pallets with integrated strapping technology, several issues limit their widespread adoption. These include higher initial costs, the need for regular maintenance and potential repairs, limited flexibility for various load types, compatibility issues with existing material handling equipment, increased pallet weight impacting transportation costs and handling efficiency, complexities in recycling and disposal due to the mix of materials used, and additional training requirements for effective and safe use. Addressing these challenges, the present invention aims to provide an improved solution for securing goods on pallets, enhancing load stability and protection while mitigating the drawbacks of current technologies.
The present invention provides a pallet retrofit system and method that is operable to improve a pallet with a pallet wrapping system that is operable to secure goods. The system may enhance the stability and protection of loads (e.g., goods, boxes, parcels, etc.) during transportation and storage by incorporating a series of strategically positioned blocks and adjustable straps. The blocks may be mounted on the pallet to form a stable structure for attaching a plurality of straps, which apply a uniform tension across the load. The retrofit system of the present invention is operable to transform a standard pallet into a secure transport platform, reducing the risk of damage to goods while maintaining ease of use and adaptability.
In some embodiments, the system may include a plurality of blocks, each featuring a substantially rectangular body with a cutout that may include a securing plate and centered anchor. These blocks are strategically positioned around the perimeter of the pallet, adjacent to its vertical support columns, to provide optimal balance and strength, and to allow the forks of a forklift to engage with a top deck of the pallet when in transport. In such implementations, the blocks allow for the distribution of pressure across the entire load, preventing individual items from shifting during transit. The blocks may be secured to the pallet using various fastening methods, such as bolts, screws, adhesives, clamps, or brackets, depending on the material and design of the pallet.
In some embodiments, pallets may be constructed from various materials, and the blocks may be constructed of a complementary material to ensure optimal performance and compatibility. For example, and not limiting the invention, for a wood pallet, blocks may be constructed from hardwood or plywood, which can be securely attached using screws or nails, providing a strong and durable connection. For plastic pallets made from materials such as high-density polyethylene (HDPE), blocks may also be made from similar plastics, and can be fastened using self-tapping screws or plastic welding techniques to ensure a robust bond. For metal pallets, such as those made from aluminum or steel, blocks constructed from the same metals are ideal and can be secured with bolts or rivets for high-strength attachment. In applications where mixed materials are used, adhesives such as epoxy or construction-grade glue may provide additional security, especially when drilling into the pallet is not feasible. Clamps or brackets may also be employed for quick installation and removal, offering flexibility and adaptability for scenarios requiring dynamic loading and unloading.
In some embodiments, the strap may be adjustable and may have two strap pieces connected through a ratcheting mechanism. This mechanism enables precise tensioning of the straps, allowing the user to securely fasten goods to the pallet with ease. The straps are equipped with cable fasteners that engage the anchors on the blocks, ensuring a firm hold on the load. The strap material may be selected for its flexibility and durability, being resistant to tearing and abrasion, thus ensuring the goods remain stable under various transportation conditions.
In some embodiments, the strap system may incorporate a net that provides an additional layer of security. The net may be operable to envelop the goods completely, distributing pressure evenly across the load and minimizing the risk of movement during transit. Made from durable materials like nylon or polyester, the net is reinforced at its edges and corners to withstand the rigors of transport. This feature is particularly useful for securing irregularly shaped or delicate items, offering protection against external impacts, and ensuring the integrity of the palletized load.
In some embodiments, the straps may include alternative securing mechanisms and configurations to accommodate a variety of pallet designs and load requirements. These alternatives may include the use of bungee-style cables with elastic properties for added flexibility, or different types of fasteners and securing plates to suit specific applications. By providing a versatile and adaptable solution, the invention addresses the limitations of existing pallet securing systems, offering enhanced load stability and protection while being easy to implement and cost-effective.
In one aspect, the invention relates to a pallet retrofit system designed to secure goods on a pallet. The system may include a pallet with a top deck, a bottom deck, and a series of vertical support columns that interconnect these decks to maintain structural integrity. A plurality of blocks, each with a substantially rectangular body, may be symmetrically positioned around the perimeter of the pallet. These blocks may have a first side, a second side, a top surface, a bottom surface, and a front surface with a cutout containing an anchor. A strap with two ends may be used, where each end secures a cable fastener that can be removably engaged with the anchor. This strap may extend over goods placed on the pallet, providing tension and stability to the load during transportation and storage. The blocks are symmetrically arranged between the top and bottom decks, adjacent to at least one of the vertical support columns.
In another aspect, each block may be symmetrically positioned and fastened to the top deck using various fasteners or adhesives. Each block may also have a corresponding block on the opposite side of the pallet, forming a block pair. These block pairs can receive cable fasteners attached to the strap, allowing the strap to exert linear and uniform pressure on the goods. The strap may consist of a first strap piece and a second strap piece, each equipped with a cable fastener at one end. A ratcheting mechanism may connect the two strap pieces, allowing incremental tightening to secure the goods to the pallet effectively. The system may also include a net secured to each strap, covering the goods entirely and providing an additional layer of security by distributing pressure evenly across the surface to prevent shifting and damage during transit. The strap may be constructed from a flexible, durable material that resists tearing and abrasion, ensuring reliable securing of goods under various transportation conditions.
In a further aspect, the pallet retrofit system may involve integrating an adjustable strapping system into a pallet. This includes a block with a substantially rectangular body positioned at a corner of the pallet, featuring a top surface, a bottom surface, and at least two sides aligned with the pallet's edges. The block may have a front surface with a cutout containing a securing plate and a centered anchor for engaging a cable fastener. A strap with a first strap piece and a second strap piece, each having a cable fastener at one end, may be incorporated, with a ratcheting mechanism operably connected between the strap pieces to allow incremental tightening. The system may include fastening mechanisms like bolts, screws, adhesives, clamps, or brackets to secure the block between the top and bottom decks adjacent to at least one vertical support column. A net secured to the straps may cover the goods entirely, providing additional security and distributing pressure evenly.
In yet another aspect, the invention provides a method for incorporating a retrofit system into a pallet and securing goods. This involves providing a pallet with a top deck, a bottom deck, and vertical support columns. A plurality of blocks, each with a rectangular body and a front surface having a cutout with a securing plate and a centered anchor, may be symmetrically positioned around the pallet's perimeter. The blocks may be secured to the pallet using a fastening mechanism, ensuring they are fixed between the decks. Goods are placed on the pallet, and a strap with a first and second piece, each with a cable fastener, may be attached to anchors on opposite sides of the pallet. Engaging a ratcheting mechanism between the strap pieces allows for incremental tightening and securing of the goods. A net secured to the straps may provide additional protection and distribute pressure evenly across the goods, preventing shifting and damage. Fastening mechanisms may include bolts, screws, adhesives, clamps, or brackets, selected based on the pallet's material. The net may be made from materials like nylon, polyester, or Kevlar, with reinforced edges and corners to enhance durability. Each block may have a corresponding block on the opposite side of the pallet, forming pairs that receive cable fasteners, with the strap applying linear and uniform pressure on the goods. The net may be adjustable to conform to various load sizes and shapes, further enhancing security.
