Advantages of Dynamic Storage
Dynamic technology is considered, in short, the “state of the art” in terms of storage systems due to several advantages
According to Balduir Carletto, Professor of Logistics at Faculdade Santana, in Ponta Grossa, Paraná, “dynamic storage structures are racks with rollers, which facilitate the controlled movement of loads, taking advantage of the force of gravity.” Such structures typically have multiple floor-to-ceiling planes. Each storage plane is designed with a slight slope, which allows the gradual sliding of the box or pallet where the goods are stored.
In other words, we can say that it is a system characterized by the application of inclined roller tracks in the different storage levels of the structure, which allow the positioning of the pallets at one of the ends. By gravity, these units move to the other end with constant acceleration, thanks to a device called a speed regulator, installed one at each pallet position under the tracks and in direct contact with the rollers. Its actuation, by means of centrifugal force, provides the necessary braking to keep the acceleration of the load units constant. Thus, the speed is controlled, preventing the impact and the fall of products when the pallet arrives at the other end or when it accumulates, along the storage tunnels.
This movement, made only with the action of gravity, demonstrates the efficiency and sustainability of the system, which, in addition to not using any type of external energy to move the pallets within the structure (thus representing a great saving of energy and fuel of forklifts), it demands little or no maintenance throughout its useful life, thus representing the lowest operational cost existing among the storage and cargo handling systems.
Finally, dynamic technology is considered the “state of the art” in terms of storage systems, due to the characteristics already described and also because it has the function of moving palletized goods in the same system, with efficiency and sustainability.
Efficiency is also evidenced by the operation, considering that there is an entry position and an exit position, which guarantees FIFO (First In, First Out, in Portuguese, PEPS, Primeiro que Entra, Primeiro que Sai), in addition to the immediate availability of the storage position as soon as the pallet is removed from the exit position, thus characterizing 100% occupancy during the work, without the harmful “hive effect”.
- EXPLAINING: “beehive effect” or honycomb” is a synonym for inefficiency in the storage operation (in–out), caused by not using the total available cubic capacity, which generates up to 45% loss of storage space in the structures. Simply put, the available space is not fully utilized.
The Dynamic System guarantees the best use of the internal space of a warehouse without the higher costs of an automated version. In addition, it allows for the intelligent handling of products, in an organized way, reducing internal paths and facilitating the loading and unloading process, which generates substantial savings for the company that adopts it.
The speed regulation system was created in the 1950s by inventors Shultz and Begger, who developed and patented the product, industrializing it for several years. They ended up selling the company and a few years later, when the patent expired, several other manufacturers made the invention available on the market. It is based on a reduction system by means of gears connected from the outer cap of the roller to the shaft and increases the rotation of the central shaft by activating, by centrifugal action, a system of expansive inserts that rub against the outer cap, which in turn is in contact with the rollers of the tracks through which the pallets slide. There are therefore two corridors around the structure (minimum). In one of them the goods are deposited. In the other, the withdrawal of what was stored takes place. This model is suitable for those who work with high turnover products, such as the food sector, for example. FIFO (or PEPS) offers many advantages to adopters:
- Versatile system, as it can be applied to any type of product;
- Provides greater control over the stock, as the movement of products follows a logical order of entry and exit;
- Greater safety in the operation, since the inflow and outflow is organized with a defined and mandatory direction.
- It promotes great economy in the handling of forklifts, considering that much of the movement that would be done with forklifts, will be done with the action of gravity.
- It facilitates the management of self life (expiration), since products with an expiration date close to expiry must leave before the dynamic structure;
- It provides better volumetric use of the warehouse space due to the high storage density. Also due to the fact that when removing a pallet, the storage position becomes available simultaneously.
- It does not require the use of any energy, being totally sustainable, the movement within the structure by the action of gravity.
- Extremely low maintenance cost, tending to zero if the use is adequate to its dimension and care is taken in the operation of the forklifts.
- Extremely safe as the movement is always controlled by speed reducers built into the tracks.
In the Intralogistics sector, dynamic structures are also used in the Push Back model, combined with the LIFO (Last In, First Out) system. It generates savings in the layout of the internal space of the warehouse, as the same aisle is used to place and remove products from the storage structure. However, it is not suitable for goods with a very short expiration date. Items such as home appliances could be stored in this mode without any problems. We, at Águia Sistemas, also have this type of product to offer, with the following characteristics:
- Made with steel roller tracks and precision bearings
- Produced within the necessary safety standards;
- Better use of spaces;
- Allows the creation of several levels, taking advantage of the available height and depth space;
- It uses the action of gravity, not requiring automation.
Among the dynamic storage structures, we also have the Flow Rack configuration, which, according to the website aguiasistemas.com, “is an efficient system for the manual storage of boxes and packages that allows the so-called FIFO (First In – First Out) operation. queue form, which helps in the organization of small volumes. They are rotating systems, which work by the action of gravity, making the replacement and handling of stocked items even easier and more practical. Flow Racks can be used in conjunction with Conveyor Systems in picking areas, making the operator’s work more organized. Its plans are adjustable according to the operational height and box storage needs. They can also be used in conjunction with the mezzanine structure in order to provide better vertical use. In addition, they can be used integrated with pick-to-light or pick-by-light systems in order to reduce operational error”.
It is important to note that dynamic structures are practically perfect in terms of storage and cargo handling systems. Firstly, because they combine the two basic functions of Intralogistics, that is, storage and movement of goods. Secondly, due to the intelligent use of gravity, allowing the movement and accumulation of pallets in a safe and free way. To summarize, to this day it is the most sustainable system available on the international market.
In short, using the force of gravity in favor of the storage system presents operational and financial advantages for the entrepreneur, facilitating the daily life of the Logistics sector. Águia Sistemas has decades of experience in the construction of dynamic storage structures, always developing the best project for each client, in a personalized way.
