Belt conveyors are suitable for conveying all kinds of bulk materials, as well as for conveying finished items with low unit mass on assembly, inspection, and testing production lines. According to the different flexible conveyor belts, it can be divided into: fabric core tape, fabric core PVC belt, steel belt, mesh belt and so on. The fabric core can be divided into cotton canvas, nylon canvas (blN), polyester nylon interwoven canvas (tian) and so on. The shape of the upper roller on the belt conveyor can be trough and flat. When conveying bulk materials, the trough upper roller is often used, and the groove angle can be 20 degrees, 30 degrees, 35 degrees, embroidery, etc. The flat top roller can also transport bulk materials, but it is relatively small, and is mainly used to transport pieces of goods. The belt width of the general belt conveyor has 6 standard specifications: 500 mm, 650 mm, 800 mm, 1000 mm, 1200 mm and l400 mm. The belt speed is usually 1.25~5.0 m/s. Sometimes belt conveyors are also connected with other types of conveyors to form a mixed transportation system. 2. Roller Conveyor Roller conveyor is a conveyor that uses the rotation of rollers to convey articles. It can be transported along a horizontal or curved path, has a simple structure, is convenient to install, use, and maintain. Irregular items can be transported on pallets or pallets. According to the driving mode, it can be divided into: unpowered roller conveyor, power roller conveyor (chain drive, friction drive). According to the curve section of the unpowered roller conveyor, it can be divided into: cylindrical roller type, tapered roller type, differential roller type, short roller differential type, etc. According to the form of the switch device, it can be divided into: curve section switch, branch road diversion, plane diversion, trolley switch, right angle switch, turntable switch, roller conveyor lifting device switch and so on. 3. Roller Conveyor Roller conveyor is a conveyor that uses rollers instead of rollers. Its simple structure is generally used for unpowered drive, and is suitable for short-distance transportation of packaged goods or materials on the entire bottom surface. (This article was originally created by Guangzhou to Baoshan Logistics, and edited from Guangzhou to Lijiang Logistics). 4. Chain Conveyor Chain conveyors are hauled and carried by chains, or carried by slats, metal nets, rollers, etc. installed on the chain. Conveyor for materials. According to the different bearing surfaces installed on the chain, it can be divided into: chain type, chain plate type, chain net type, slat type, chain bucket type, pallet type, trolley type, in addition to other conveyors, lifting devices, etc. Form a production line with various functions. 5. Suspension conveyor Suspension conveyor is a chain (or steel cable) traction type continuous conveyor. Suspended conveyors are widely used in mass production enterprises, as mechanized continuous transportation equipment on the internal assembly line of the workshop or between the workshop and the workshop to transport the rough, semi-finished products and other packaged crystals. Suspended conveyors have been widely used in automobiles, home appliances, clothing, slaughter, postal services, etc. Ordinary suspension conveyor system generally consists of a closed circuit consisting of a driving device, a tensioning device, a traction member, a carrying trolley and a safety device, and its track generally uses rolled steel. When the load is heavier, cold-pushed detachable chains or forged detachable chains are used for the traction parts, and double hinges can be used when the load is lighter. Ordinary suspended conveyors can realize horizontal or vertical transportation, turning, etc., and are suspended under the factory building frame or floor beam to save floor space. Suspended conveyors can also realize long-distance transportation, from tens of meters to hundreds of meters or even thousands of meters, and the speed range can be from a few tenths of a meter per minute to 50 meters per minute. According to the different connection methods of traction parts and load-bearing parts, it can be divided into: general suspension conveyor (lift suspension conveyor), push suspension conveyor, drag suspension conveyor, accumulation suspension conveyor; according to the load-bearing parts Different support methods can be divided into: aerial hanging type, ground support type, etc. 6. Monorail trolley conveyor The monorail trolley conveyor is an electric trolley running on a specific aerial track, which can form a load-bearing and fully automatic material handling system. It is different from the suspension conveyor. It is not driven by chains and other traction parts, but each trolley has its own separate driving device, so that it has great flexibility and is not restricted by chains and other traction parts. In the past 10 years, the monorail trolley conveyor has developed rapidly. In addition to the advantages of air transportation, reduced floor space, and full use of plant space, it also has the following characteristics. 1) Each car in the system is driven independently. 2) The material is composed of rails, translation switches, turntables, elevator sections, etc., forming a three-dimensional transportation network. 3) A variety of control methods can be used, such as centralized control, decentralized control, and distributed control. The trolley performs fully automatic operation according to the set program. 4) It can be used as a random material supply system. The station requesting a car can be applied randomly, and the characteristic address code of the requesting station can be written randomly through the car, and the material can be supplied directly to the requesting station. 5) It can be used as a sorting and distribution system. The loading trolley carries the characteristic address code according to the different types of goods carried, and the address reading station is set up on the ground, which can realize automatic sorting and distribution operations. It is widely used in the automobile, post and telecommunications industries, as well as factories The assembly line, inspection line and so on. The monorail electric trolley does not need towing the chain and the running track of the chain, and the expansion and modification of the line are more convenient. The longest monorail electric trolley line is several kilometers long. It can move forward and backward, and achieve a variety of operating speeds. The speed of the straight line can reach 100 meters per minute, and it will decelerate to a few meters per minute before reaching the station, and the parking accuracy can reach 10 mm. The monorail electric trolley conveyor is suitable for transportation and storage between factories, transportation between factories and workshops, distribution centers, single-story, high-rise buildings and other internal multi-point and multi-level transportation. 1540
