The role of palletisers in automated warehouses

Under the specific necessity of the development trend of manufacturing and the actual possibility of the development trend of high technology level, the automated three-dimensional warehouse occurred gradually in the early fifties. The development of the automated three-dimensional warehouse was the result of the development of the production process after the Second World War. 1950 in Britain, the first manually operated bridge palletizer lifting equipment was created, and the definition of the high-rise residential storage rack was clearly presented, which is considered to be the prototype of automated warehouses. 1960 and onwards, alleyway palletizers slowly replaced bridge palletizers, and since then, the range of applications and characteristics of palletizers has been very wide. After 1960, the bridge-type palletizer slowly replaced the bridge-type palletizer, and since then the application scope and characteristics of the palletizer have a very big development trend, especially in Japan, the development trend of automated three-dimensional warehouses is fast, and at this stage, Japan's automated warehousing technology and automated warehouses have a stable position at the front end of the world.

The development trend of automation technology in the warehousing and logistics industry is divided into five links: human warehousing and logistics links, automated warehousing and logistics links, integrated warehousing and logistics links, intelligent system links and intelligent automation links. In China's automated three-dimensional warehouse and raw materials and equipment handling research and development is not late, developed into the first bridge stacking crane in 1963, the Ministry of Machinery, Beijing lifting and transporting machinery research laboratory, 1973, gradually developed in China's first computer system controlled by the automated three-dimensional warehouse height clever meters, the Ministry of Machinery, lifting and lifting the undertaking, the library of funds put into operation in 1980. In which intelligent automated warehousing and logistics in the mid to late nineties and its twenty-first century, many years, is the key development prospects for the automation of warehousing and logistics technology.

Palletizer is the key component of automated three-dimensional warehouse system software, it is the implementation of all the system software components, inventory goods from the inbound and outbound platform to store goods accurately into the storage space, picking up goods from the storage space to take the goods back to the inbound and outbound platform. Regardless of the type of palletizer, it is generally composed of a level lifting mechanism, a lifting organization, a loading table and fork organization, a sound card frame and electrical equipment. Although each manufacturer has originality and there are some differences in the structure form, it can be said that all the palletizers are nothing more than a part of the sound card rack, loading table, telescopic forks, road track and automatic control system. It is a substance under the definition of frankly high-rise housing, fast, high density storage.

The development trend of the palletizer pre three-dimensional warehouse application of the palletizer to the bridge crane as the basic, this kind of palletizer is to lifting equipment on the main beam suspension of a gantry, the use of gantry left and right and rotation to transport goods. 1960 up and down in foreign countries occurred in the alley type palletizer, then the alley type palletizer slowly replaced by the net weight and the distance between the limitations of the bridge type palletizer. 1967 Japan installed the In 1967, Japan installed a high-rise residential palletizer with a height-to-width ratio of 1015 meters, and in 1969, a networked fully automated warehouse occurred, and in China, a three-dimensional warehouse with alley-type palletizers was gradually selected for scientific research in the early 1970s. At the present stage, the technology of palletizers has gained a significant development trend, and the control system, accuracy level, and operation speed have all gained a very large level of improvement. The lifting speed of aisle-type palletizer has long been able to reach 90m/min, and the operation speed has reached 240m/min. In some three-dimensional warehouses, the upper and lower double floors are transported by aisle-type palletizers, which improves the ability to enter and exit the warehouses.

According to the current standard machinery manufacturing norms, there are many ways to categorize the rail-train-aisle palletizers, such as categorizing them according to the support method, the main purpose, the manipulation method, the structure, and the operation trajectory, etc. The research on palletizers' dynamic characteristics reflects the fact that they have a good performance. The key index values reflecting the good or bad dynamic characteristics of the palletizer are: operation speed, increase speed, fork speed, stability, address precision, etc. Regardless of the type of palletizer, it is generally composed of a level lifting mechanism, lifting organization, loading table and fork organization, sound card frame and electrical equipment and other basic parts. Along with the continuous development of scientific and technological progress, the technological strength of automated three-dimensional warehouses and the dynamic characteristics of warehousing and logistics industrial equipment continue to improve. For example, the operation of the palletizer has been changed from the letter motor of the 1970s to the frequency conversion type variable speed, and the speed has been increased from 550m/min to 4160m/min, and the palletizer with small load capacity overseas can reach 300m/min at the most; the increase of the promotion has been improved from the single-speed motor of the 1970s to the frequency conversion type variable speed, and the speed has been increased from 416m/min to 025m/min; the fork operation has also been improved from the single-speed motor of the 1970s to the frequency conversion type variable speed, and the speed has been increased from 416m/min to 025m/min.
