The Different Types Of Palletizing Systems
Palletizing Systems are tools used for the safe loading, moving and storing of pallets prior to shipping and during storage as well. Most manufacturing and warehousing facilities employ automated palletizing systems, robotic palletizing systems or semi-automated palletizing systems for safe, rapid unloading and pallet loading. These systems increase productivity and decrease the cost of managing the pallets by reducing the labor costs. The most popular form of automated palletizing is Rotary Table Palletizing. It is considered as the most economic, productive and versatile palletizing method.
Rotary Table Palletizing System involves the use of a rotary conveyor that moves the pallets at pre-determined speeds on the face of a ramp, reducing the level of manual labor required. This system has the ability to level the pallets quickly and easily without any interference with the goods or products. Rotary palletizing systems have various other advantages, such as reduced energy consumption, reduction in OSHA regulations, automated loading & unloading, reduction of transport time and cost. Moreover, the mechanical design of a rotary pallet rack reduces rack damage and hence, makes the system economical. The system can be easily customized for varying customer requirements.
Rotary palletizing systems are available in different types. The first one is the Single compartment palletizer system, which is a self contained unit that offers the best of palletizing efficiency and flexibility. This type of system uses one continuous conveyor belt, which means no secondary conveyors are needed. Underneath this belt, are several parallel steel belts, which are attached to the innermost roller stack.
The second type is the High level palletizing systems, which offer maximum usage of space. This is used in industries where the maximum weight and volume are needed. However, in order to use high level palletizing systems, a number of steps are required in the process. These include loading & unloading, stacking & leveling, and breaking down of finished pallets. For this, a number of high level palletized racks are required, which are attached to the in-line palletizer systems.
The third type of palletizing is the direct line palletizing, which uses a robotic arm tool to load and unload the pallets. It is highly effective, as compared to the eoat system, as it does not require any secondary moving parts, and the pallets can be moved very easily. In the case of the eoat system, the conveyor belts have to be manually adjusted, which makes them very slow, and sometimes faulty.
The fourth type of palletizing is the indirect line palletizing, which uses an overhead criss-cross layer, to hold top frames, and also requires a support structure for leveling. The top frames are placed on an inflatable structure, which is then raised to the desired height. The inflatable structure is deflated, and the frame is then lifted off from the inflatable structure. This process takes a long time in comparison to the direct line palletization system, and there are many chances of the bottom frame getting damaged. However, the indirect line palletizing system is highly effective and provides great efficiency. Hence, all types of palletizing systems need to be thoroughly researched, in order to find the best solution.
