The Research And Manufacture Of The Pallet Transfer In The Automatic Joint Lifter

The automatic cabinet is a new-style automatism store equipment. On the basis of its working principle, the automatic cabinet is divided into two types:one is automatic carousel, the other is automatic lifter. The automatic joint lifter discussed in this paper is the outspread application of the second type of production. It doesn’t simply stack with several single lifters physically. Based on the centralized control system, the automatic joint lifter can be moved in three-dimensional direction. In addition, the store capacity of the automatic joint lifter is several times larger than the single lifer due to the space be completely utilized.This article first introduces the classifying of the automatic cabinets and their basic principles and characteristics. Secondly, it analyses and contrasts various pallet transferring technologies, illuminates the characteristics of all kinds of forks, and points out that the core technology of the joint lifter lies in the fork designing. Thirdly, the article introduces the design concept of the joint lifter, and deeply discusses the principle, structure and actualization way of the three-dimensional movement of the pallet. Then it gives a detail account of the principle, mode, action process and position control of the fork pulling and pushing the pallet out of or into the shelf location, and explains the lifting structure, pointing out that the difference between the vertical lift and the joint lifter is the lifting guiding technology. The joint lifter adopts the elevator’s guiding technology and adds a balance weight system which is calculated in the article. Moreover, the article makes a force analysis about the extractor frame and a type selection calculation about the lifting motor. Then it illuminates the transverse traveling structure of the carrier. Finally, the article describes some problems which may occur during the equipment debugging process and their respective solutions.The automatic joint lifter saves the production cost and enhances the space storage capacity due to its rational design. It also improves the work efficiency by the optimized program. It helps to popularize the application of the automatic cabinets and must bring in huge market benefits.
