A clad-rack warehouse for the Lakma chemicals company
Picking is one of the primary operations of the Lakma clad-rack warehouse
Picture a fully-automated, 32 m high clad-rack warehouse built key-in-hand, with all goods managed smoothly and efficiently by the Easy WMS of Mecalux; then, add storage capacity for 15,428 pallets. That is ‘Multisoft’ in a nutshell, the 4,400 m2 sophisticated logistics complex of Lakma Strefa –one of the most cutting-edge chemicals company of Poland–, located in the town of Warszowice, in the Southern region of the country.
Leader in chemical product manufacturing
Lakma Strefa is a Polish chemical products company, whose goods are used in different industrial sectors, such as in construction, household care, professional chemicals and thermal insulation.
In 1988, the company installed its first plant in the city of Cieszyn (close to Czechia), allocated to chemical products for the building sector, in addition to varnishes and paints. Only five years later, it expanded its business by offering household chemical products.
The 1998 construction of a new manufacturing centre in the town of Warszowice, Southern Poland, was explicitly done to deal with business growth.
“Our company is flourishing, and our customers demand faster and faster product distribution, not only nationally but also to foreign markets,” explained Maciej J. Paluch, President of Lakma Strefa. The business boasts a massive distribution network that stretches through the vast majority of countries within the European Union. As a result of this expansion, Lakma Strefa has updated its laboratories, manufacturing centre and warehouses, and has set up technology in as many processes as possible.
The firm reached out to Mecalux to build it a new 4,297 m2 fully-automated distribution centre. This project was dubbed ‘Multisoft’. Automating, in the words of Maciej J. Paluch, has allowed, “maximum optimisation of the supply chain, from the storage zone up to picking orders for our customers.”
Mecalux erected the Multisoft clad-rack structure over a period of eleven months. Situated on a tract of poor-quality land that could not support such a huge, heavy building like that one that was designed, it had to be built on top of 254 serially bored foundation piles.
A 50 cm thick concrete slab rests on 220 out of 254 foundation piles. Then, the racks that comprise the clad-rack installation were placed on top of this slab. A layer of fibre cement paves the remaining 31 piles, upon which a building was erected for pick tasks, entries and exits, business offices and the changing rooms.
Multisoft is a cutting-edge, high-tech project, which is why fire safety was a priority. For this reason, Maciej J. Paluch points out, “The design and construction of this warehouse required our involvement, as well as the collaboration of Państwowa Straż Pożarna (a fire suppression service provider in Poland) so that the building would comply with all safety standards.”
Multisoft: a modern logistics centre
Multisoft is an automated clad-rack warehouse featuring four aisles of double-deep racks on each side. These racks are 32 m high and 81 m long, with fourteen storage levels, and provided a 15,428-pallet storage capacity.
The business has directly benefitted from the technology, speeding up processes to do with storage, order picking and dispatching of goods. Thanks to this, Lakma Strefa has pulled off workflows of 162 pallets/hour.
A single-mast stacker crane circulates in each aisle, operating at a speed of 160 m/min and 38 m/min when raised. The equipment runs storage tasks that, in a traditional warehouse, would be done by operators on forklifts. Its job is to move goods between racking slots and the input and output conveyors set up at one end of the aisle. In-warehouse stacker cranes have telescopic forks to access the second pallet of each location.
The logistics centre is managed in its entirety by the Easy WMS warehouse management system of Mecalux. According to Grzegorz Stokłosa, Mecalux Sales Manager in Poland, “through radiofrequency devices, it lets us control all in-warehouse processes, from receipt orders to those for dispatches, as well as the stock of stored goods.”
Soaring productivity just next door
A shorter, 8 m tall building was constructed along one of the sides of the warehouse and occupies a 2,140 m2 surface area. It is allocated to incoming and outgoing goods and order prep.
This is a bustling zone and, as such, has been specially designed so that all operations are done in the most efficient manner.
Every day, the installation receives 70 pallets from other manufacturing centres or suppliers. Workers insert pallets onto the input conveyors and, soon after, the goods pass through a checkpoint where their size, weight and status are verified to see if they match the quality requirements laid down for the automated warehouse. Once the pallet is accepted, a double-capacity transfer car collects the load and takes it right up to the storage aisle assigned by Mecalux’s Easy WMS warehouse management software.
An entry point was also opened up for goods flowing directly from the plant (around 130 pallets/day), located in premises next to the warehouse. The two buildings are interconnected via a raised, roofed-in overpass.
Picking of goods is central to Multisoft’s operations. Dozens of orders are prepared each day in a specific warehouse area enabled with gently-inclined live channels, meaning pallet move via gravity from the highest to the lowest point.
Operators access pallets directly at the front of the channels, picking boxes listed in each order with the assistance of ground-level order picker equipment. Everything is done according to the instructions the Mecalux Easy WMS warehouse management system shows on the radiofrequency devices.
On a daily basis, an average of 180 pallets flows from the warehouse, although dispatches can swell to more than 600. Despite the fact that most orders require some prior preparation, entire unsplit pallets are also distributed.
For these cases, three fast response exit points were installed in the live picking channels. Operators collect pallets using forklifts and insert these pallets directly into the transport vehicle to be shipped out.
ADVANTAGES FOR LAKMA STREFA
