Tire transport and storage system in an automated warehouse

A company in the tire industry entrusted MPL Techma with the design and construction of an intralogistics system for storing raw tires. The central component of this system is an automated high-storage warehouse.

The investor presented us with several challenges, including:

  • Ensuring a tire flow of 3200 units per day.
  • Integrating the system into the existing architecture of the production hall.
  • Coordinating with management and production systems.
  • Planning the tire layout in the warehouse to maintain access to all tire types during preventive maintenance on one module.
  • Improving energy efficiency through the use of an energy return system.
  • Automating the reception and dispatch processes from the warehouse.
  • Allowing for service works on specific parts of the warehouse without stopping the entire system.
As a result, we implemented a system consisting of four sub-warehouses, each served by an independent stacker crane.

This layout allows for the selective shutdown of a chosen sub-warehouse for preventive maintenance on one machine, without halting the others.

The warehouse accommodates tires on 1600 allocation positions in a single-deep storage system. The tires are stored on specially designed carriers or plastic pallets measuring 1200x1200x300mm.

In addition to the storage system, we provided a robotic tire loading system.

This system retrieves a single tire from the assembly trolley, identifies it through barcode scanning, changes its orientation from vertical to horizontal, and transfers it to the technological socket.

From there, the tire is placed on a storage pallet with a QR code and transported into the warehouse via roller conveyors.

The warehouse serves two additional functions dictated by the subsequent technological process. Firstly, it acts as a buffer, pairs and lays tires flat.

Secondly, it includes a robotic unloading system at the warehouse's exit. Tires are transferred from storage pallets to the technological oven trolleys. Additionally, the unloading system collaborates with an automated queue and trolley shifting system.

As part of this project, we executed, implemented, and integrated the entire control system, safety system, and WCS (Warehouse Control System) in cooperation with the production management database.

As a result, the client received an efficient system entirely designed and executed by our company, tailored to their specific needs.

Thanks to the open system and the use of commercial components, the client's maintenance services can independently diagnose and service the warehouse, minimizing downtime and maintenance costs.
