The commonly used automatic telescopic forks of stacker can be divided into two categories: 1. Single depth telescopic forks; 2. Double depth telescopic forks, which can also be simply understood as three section automatic telescopic forks or four section automatic telescopic forks (or three section automatic telescopic forks or four section automatic telescopic forks).Because the volume of the goods carried by the fork has a certain size, the relative fork body with large volume will be longer. If the fork body of the three section or three section telescopic fork (single depth telescopic fork) is too long, the lower deflection will increase, which will lead to the instability of the transferred goods and directly affect the offset between the warehouse location and the goods.Therefore, to increase the telescopic length, one section or one section of fork is used, which becomes a four section or four section fork, which is called double depth telescopic fork.
The basic structure of single depth telescopic fork (three section or three section type) is a complete telescopic mechanism composed of front fork, middle fork, fixed fork and guide roller (double depth telescopic fork is composed of front fork, upper middle fork, lower middle fork, fixed fork and guide roller).The fixed fork is installed on the loading platform, the middle fork can move outward about half of its own length under the drive of gear and rack, and the front fork extends outward from the middle point of the middle fork.
As we all know, the telescopic fork of stacker is divided into single deep telescopic fork teeth and double (multiple) deep telescopic fork teeth, and there are many working forms of telescopic fork teeth: single plate fork teeth or double combined fork teeth, multiple combined fork teeth.The specific number of forks to be used is determined by the materials and pallets stored in the stereoscopic warehouse. For small materials and pallets, single fork or single plate fork is generally used. On the contrary, multiple combined forks are configured.
At present, automated warehouse is widely used in automobile, electronics, medicine, tobacco, building materials, posts and telecommunications and many other industries. It is the key to realize the rationalization of logistics system and is of great significance to speed up logistics, improve labor productivity and reduce production costs.Among them, the stacker is an important handling, lifting and stacking equipment in the three-dimensional warehouse, which has an important impact on the efficiency of the three-dimensional warehouse.Compared with foreign technology, there is a gap in technical parameters, product coverage, technical stability and industrial scale of the fork teeth of stacker in China.
