Roller conveyor is a continuous conveying machine, mainly used to complete the conveying of finished items, and has a long history of application in modern production. In the second half of the twentieth century, all walks of life have developed by leaps and bounds, and the degree of production mechanization and automation has also been continuously improved. In particular, the widespread use of continuous production lines has injected new ideas into the widespread application and development of roller conveyors. New energy.
In the transportation of finished goods, the roller conveyor is the most commonly used conveying machinery. It not only has a simple structure and is easy to maintain, but also has flexible layout, reliable operation, and less equipment investment than other finished goods conveyors. At the same time, it can be used alone or in conjunction with other conveying machinery systems, so it has a wide range of applications and strong adaptability. In the past two decades, due to the boom in home appliance and other industries, various production lines and assembly lines composed of roller conveyors have emerged. Therefore, roller conveyors are widely used in production lines in the fields of machine manufacturing, automobile manufacturing, home appliance manufacturing, food and beverage industry, and postal and telecommunications departments to complete processing, assembly testing, packaging, storage and transportation, Various process operations such as sorting.
Due to the application of new technologies and new materials, as well as the clever use of various supporting auxiliary mechanisms, the functions of roller conveyors have been greatly extended and developed. The operating characteristics of modern roller conveyors are as follows:
- 1) It has many kinds of conveying properties, such as straight conveying, right-angle conveying, curve conveying, and gravity conveying, etc.
- 2) The height difference due to process and equipment requirements can be made up by using a lifting platform to connect the production lines into one; a hoist can also be used to connect the production lines on different floors into one, thus forming a three-dimensional production line.
- 3) During operation, the workpiece can be paused in a controlled manner to complete the processing of a certain process or wait for the next process. It can also be stored and released at regular intervals.
- 4) The roller conveyor can rotate horizontally or reversely to correct the workpiece required by a certain process.
The development of roller conveyors and the preparation of standards in our country started later than those in industrialized countries. Before the 1980s, roller conveyors were only used on a large scale in mechanized production lines in production and processing workshops (such as casting, steel rolling, engine assembly, etc.), but most of the roller conveyors used were based on Specialized or non-standard equipment is mainly used, and mass production of general-purpose products is far from forming. By the mid-1980s, my country’s industry had developed by leaps and bounds, especially the rise and drive of some emerging industries (such as automobiles, home appliances, etc.), which began to use a large number of mechanized and automated production lines, and they were gradually popularized in other industries. . The roller conveyor has also been widely used, so it has shown vigorous vitality, and its production and manufacturing scale and level have also entered a new stage. Mainly manifested in the following aspects:
- 1) The application range of roller conveyors continues to expand, and has almost spread to production lines in various industries.
- 2) The application scale of roller conveyors is gradually expanding. In the flow production line system, the range of its conveying length is constantly expanding, the conveying speed can be from less than 0lm/s to several meters per second, and the weight of transported items can be from hundreds of grams to tens of grams. Several tons, and the overall width of the item can also reach several meters.
- 3) The specialized production of roller conveyors is gradually formed. At present, there are many roller conveyor manufacturers in my country, which can produce general-purpose roller conveyors with relatively complete specifications and varieties.
- 4) The production technology level and manufacturing quality of roller conveyors have been greatly improved.
- 5) A lot of useful basic work has been done in the standardization, generalization and serialization of roller conveyors. my country’s roller conveyor industry standards were applied for project approval in November 1991, and were officially included in the “Machinery Industry Standards” of the Ministry of Mechanical and Electrical Engineering in January 1992. Formulate and revise the plan”, which was completed in early 1993.
The new roller conveyor is a new type of roller conveyor developed based on the basic theory of three-phase AC linear motors. This new type of roller conveyor is mainly used to transport relatively heavy objects such as strips and blocks. It is a kind of transportation equipment in which the roller serves as both a traction mechanism and a load-bearing mechanism. In the metallurgical industry, hot rolling and hot continuous casting steel billets, rolled steel pipes, steel plates and profiles, etc., in the building materials industry, flat glass, wood and plates, etc., in the logistics industry, airport luggage transportation lines, and in the machinery industry, engines, Roller conveyors are widely used in the assembly lines of mechanical equipment such as gearboxes, reducers, and motorcycles.
Domestic literature has reported on the research and application of raceway (roller conveyor) conveyors and the development and application of linear induction motors. Among them, there are also reports on the specific application of linear induction motors in conveyors. Relevant reports are as follows:
Design and application of curved power roller conveyors, types and selection of roller conveyors, telescopic roller conveyors, turntable roller conveyors, multi-channel right-angle turn roller conveyors, linear motor driven plate conveyors, straight Driven belt conveyor, etc.
