The function of palletizing machine in automatic warehouse

In the production manufacturing development trend of the specific must and high and new technology level of the actual trend of development is very likely, the beginning of the 1950s gradually occurred automated three-dimensional warehouse. The occurrence and development trend of warehouse shelves in high-rise residential buildings is the result of the development trend of production technology after the Second World War. In 1950, the United Kingdom was the first to create manual bridge stacking machine lifting equipment, in addition to clearly put forward the definition of high-rise residential storage shelves, is considered to be the prototype of automated warehouse. After 1960, laneway palletizing machine slowly replaced bridge palletizing machine. Since then, the application scope and characteristics of palletizing machine have a very large development trend, especially in Japan, the development trend of automated three-dimensional warehouse is fast. At the present stage, Japan's automated warehouse technology and the volume of automated warehouse are stable in the global front end.

The development trend of automation technology in warehousing and logistics industry is divided into five links: manpower warehousing and logistics link, automated warehousing and logistics link, integrated warehousing and logistics link, intelligent system link and intelligent automation link. Equipment for automated stereoscopic warehouse and raw materials handling in China research and development is not late, 1963 research and development into the first bridge type stacker crane mechanical lifting conveying machinery research center, Beijing 1973 gradually development in our country, the first is controlled by a computer system of the automatic stereo warehouse smart meters high, mechanical lifting to. The bank became operational in 1980. Among them, intelligent automatic warehousing and logistics in the late 1990s and many years in the 21st century is the key development prospect of warehousing and logistics automation technology.

Palletizing machine is a key component of automatic three-dimensional warehouse system software, it is the implementation of all system software components, inventory goods will be accurate storage from the delivery platform into the storage, when the goods from the storage to return to the delivery platform. No matter what kind of palletizing machine, it is generally composed of leveling lifting mechanism, lifting organization, loading platform and cargo fork organization, sound card frame and electrical equipment. Although each manufacturer has originality, the structure form has some differences, but can be said to be the same, all palleting machine is nothing more than by sound card frame, loading platform, telescopic fork, rail and automatic control system and other parts of the composition. It is in the definition of high-rise housing, fast, dense storage.

The development trend of the early three-dimensional warehouse application of the palletizer to bridge crane as the basic, this kind of palletizer is a gantry suspension on the main beam of the lifting equipment, the use of gantry around and rotation to transport goods. In 1960 up and down in foreign countries, the roadway type palletizing machine, then the roadway type palletizing machine slowly replaced by the net weight and span limited bridge palletizing machine. In 1967, Japan installed a high-rise residential palletizing machine with a height and width ratio of 1015 meters. In 1969, there was a fully automated warehouse connected to the Internet. In China, it was a three-dimensional warehouse with laneway palletizing machine that was gradually studied scientifically in the early 1970s. At this stage, the palletizer technology has gained a major development trend, and the control system, accuracy level and operation speed have been greatly improved. The lifting speed of the laneway palletizer has long been able to do 90m/min, and the operation speed is 240m/min. In some three-dimensional warehouses, the upper and lower double layers are selected to carry out the transport work with the laneway palletizer to improve the working capacity of the warehouse.

According to the current standard machinery manufacturing specifications, rail train laneway type palletizing machine classification method many, such as according to the support method, main use, control method, structure, operation movement track classification. The key values of the indexes reflecting the dynamic characteristics of palletiering machine are: operation speed, increase speed, fork speed, stability, address precision and so on. No matter what kind of palletizing machine is generally composed of leveling lifting mechanism, lifting organization, loading platform and cargo fork organization, sound card frame and electrical equipment and other basic parts. With the continuous development of scientific and technological progress, the technical strength of automated three-dimensional warehouse and the dynamic characteristics of storage and logistics industrial equipment are also continuously improving. For example, the operation of palletizer has been promoted by the letter motor in the 1970s into variable frequency variable speed, the speed increased from 550m/min to 4160m/min, overseas small cargo palletizer maximum can reach 300m/min; The drive has been improved from the single-speed motor in the 1970s to the variable frequency variable speed, with the speed increased from 416m/min to 025m/min. The operation of the fork has also been improved from single speed motor to variable frequency variable speed, with the speed increased from 8m/min to 435m/min. At the level of automatic control system of palletizing machine, closed-loop control system variable frequency variable speed system software and Profibus system bus control are also selected. Even so, the current domestic palletizing machine operation speed is still maintained at the maximum of 160m/min; Increase the speed at 080m/min; The speed of the fork has been maintained at 030m/min; Address selection of optical detection, precision is not enough, high address error rate.
