Storage for Small Parts


In this section we seek to define the parameters that must be taken into account in order to achieve a nearly perfect store of small pieces. The means to achieve this premise in the most efficient and rational way possible is the automation of processes. However, it must never be forgotten that when designing a warehouse, especially if it is robotized, it must be borne in mind that the cost of the installation must be proportionate to the total cost of the operation. In other words, a balance between cost and utility must be achieved.

The man-to-product strategy

The principle of man to product is the most conventional and classic of the existing ones. In this mode, the products are stored in shelves placed in different ways depending on the chosen system. The maintenance of these elements is done manually - and the product is located piece by piece - or mechanized, for which full load units are handled, usually boxes or containers. The extraction of the units is usually carried out manually, for which the operator has to move on foot or mounted on a machine to the place where the reference to be found is located according to the order that has been placed. received.

Shelves on one floor

This type of shelves, which are generally of small load capacity, are distributed in the warehouse leaving a small corridor for the passage of the operator and the picking cart. Currently there are very sophisticated systems with drawers of many sizes and arrangements that adapt to all product volumes and all industrial activities. Usually low levels are dedicated to housing the heavier products and these shelves are usually not very high. This characteristic will depend on the needs of each industry and each warehouse, but it should be borne in mind that very high structures hinder rapid access to products located in the highest positions. In some cases, stairs or trolleys, usually manual, are needed, which slow down the process of taking and placing the units.

Multi-store shelves

This climate controlled storage units San Antonio, system responds to the same principles as the previous one since, in practice, it is two or more warehouses of a plant installed one on top of the other. With this a greater storage capacity is achieved by having higher shelves equipped with walkways. With this system, the need to use manual ladders or ladder carts is eliminated and, therefore, a relative decrease of the time used for each item collected or deposited is achieved. In the warehouses with this system it is impossible to use mechanical means, except in the lower floor or in the high resistance mezzanines (which have, however, a higher installation cost). However, forklifts or other means, such as elevators or hoists, can be used to feed the upper floors with complete pallets.

Mobile shelving

The system of mobile shelving saves a lot of space, since the number of aisles is reduced, generally, to only one. However, when the use of the shelves is very frequent or if the number of shelves is very large, systems can be designed with more than one aisle, by grouping the shelves in several blocks. The placement and collection of the products is carried out exclusively manually and, given that the distances that must be covered are much shorter than in the case of fixed shelving systems, the time needed to open the aisle is largely compensated

Narrow aisle warehouses

Within the systems that respond to the principle of man to product, storage structures with narrow corridors are those that present better indices in terms of land use, handling capacity and handling cost. On the other hand, the investment cost of this modality is higher than the previous ones, although it remains at acceptable levels. The space occupied on the surface is highly restricted with the arrangement of separation corridors between very small loads that can reach 1,000 mm. However, the most common is to enable corridors between 1,500 and 1,700 mm wide to be able to use full loads. This system allows to take advantage of the total height of the warehouse up to the same roof.
