The warehouse is where the goods are simply stored? Obviously not, in the warehouse, every link from unloading, putting on the shelf to leaving the warehouse is very particular. A seemingly simple shelf has university questions hidden inside. In the same space, how the one shelf can carry the most goods and maximize the use of space is a problem that the warehousing industry has been paying more attention to.
In recent years, with the surge in storage demand and the tight land area, the concept of dense storage has become popular. The shuttle racking system came into being as one of the solutions. It is a racking system used by racks, shuttles and forklifts. This kind of shelf can not only save storage space greatly, but also store goods efficiently and flexibly.
First, the characteristics of shuttle shelves
Dense: The highest density of goods is stored, the warehouse space is fully utilized, the warehouse construction cost is significantly reduced, and the space utilization rate is more than 80%;
Flexibility: The goods can be freely selected in first-in first-out and first-in first-out, so that the goods can be accessed more flexibly;
Efficient: The forklift does not need to drive in, saving operation time and improving the safety of personnel and goods;
Safety: The anti-seismic safety performance is much higher than other forms of shelves, the structure is more stable, and the safety factor is higher.
2. Design principles
1. Planning size
L is the clear width of the channel;
W is the width of the tray (into the fork direction);
H is the height of the first layer: 340 mm (gasket type), 430 mm (adjustable foot type);
h is the reserved height of about 100 mm from the top of the cargo to the bottom of the upper beam.
2. Number of shuttles
According to the number of pallets entering and leaving the warehouse every day and working hours, the round-trip time of the forklift operation, the depth of the roadway (the best efficiency is 20 pallet depth, the deeper the roadway, the longer the access time, the number of shuttles and forklifts to be matched Increase) Three points to confirm the length of the guide rail, the number of shuttles and the number of forklifts.
3. Common shuttle car parameters
Shuttle speed: normal load speed: 0.6~0.8 m/s adjustable;
Normal speed of empty shuttle: 0.7~0.9m/s adjustable;
Slow speed before stopping the shuttle: 0.1-0.2m/s adjustable;
Shuttle car manual advance and retreat speed: 0.1-0.2m/s adjustable;
The maximum rated load of the shuttle: 1500 kg.
Shuttle shelves have very obvious advantages in traditional production enterprises. Taking the shuttle rack as a prototype and combining with the specific needs of users, a shuttle three-dimensional warehouse system, a multi-layer shuttle system, etc. are derived, with a height of more than 20 meters. The benefits created by the space saving of the shuttle rack system are increasing year by year. Therefore, how to use the shuttle racking system reasonably in the future will become a topic of great value.
The Hegerls shuttle system increases the SKU of the goods, and greatly reduces the accident rate of forklift impacts. The damage to the shelves is almost negligible. According to the needs of customers, the shuttle system can realize semi-automatic and fully automated storage. It is an efficient alternative to short-term storage and drive-in shelves. It is widely used in the following areas: cold storage, food and beverage industry, meat processing industry, etc.
Hegerls Shuttle System was awarded the Shuttle Vehicle Patent Certificate issued by the State Intellectual Property Office as early as 2014. It has a unique proprietary technology, especially at the international leading level in large-tonnage lifting.
In recent years, Chilean OSCAR, UAE ALLM, Thailand JM, Thailand LSP and other high-density shuttle intelligent storage projects have been completed.
