Conveyors have different classifications and different titles according to different purposes and functions. We will come to you today to learn about intermittent conveyors.

Intermittent conveyors are mainly used for conveying pallets, bags or other fixed-size container units. They are essential transportation equipments for logistics distribution centers and warehouses, with horizontal and vertical transportation. According to the presence or absence of power source of the conveyor, it can be divided into two categories: gravity type and power type. Gravity conveyors can be divided into three types: roller type, drum type and ball type depending on the rolling elements. Power conveyors are generally powered by electric motors. According to different driving media, they can be divided into chain conveyors, roller conveyors, flat belt conveyors and overhead conveyors. The following describes the commonly used gravity conveyors and power conveyors.
Gravity Conveyor The so-called gravity conveyor uses the gravity of the conveying object itself as the power to slide from top to bottom on a tilted conveyor. The inclination of the gravity conveyor is related to the friction of the rolling element, the inertia of the cargo and rolling elements and the speed of the sliding, especially the weight of the cargo, the packaging material and the flatness of the bottom surface of the package. The slope is generally 2 % to 5%. In order to control the speed of the goods on the inclined conveyor not too high, the large inclined conveyor is generally equipped with a brake roller. Gravity conveyors have the advantage of low cost and ease of installation and expansion. According to the different rolling elements, it can be divided into roller type, drum type and ball type. Among them, drum type conveyors are generally used in the food and beverage industry and casting workshops, rolling mills, wood processing plants, warehouses, distribution centers and post offices. Roller and ball are mostly used in distribution centers and handicraft industries. The main features of the gravity roller conveyor are light weight, easy handling and convenient loading and unloading. For items with a soft surface, such as a cloth bag, the roller type has better conveyability than the drum type, but for a container with a hole at the bottom, it is not suitable to use a roller conveyor. In order to smooth the delivery of the item, at any time an item should be supported by at least 5 wheels distributed over three axes. The application range of gravity roller conveyors is much larger than that of roller conveyors. Generally not applicable to the goods of the roller conveyor, such as plastic baskets, barrels, etc. are applicable to the drum conveyor. When the gravity roller conveyor transports the goods, when transporting the hard substrate, at least 3 rollers support the articles to ensure the normal conveying work, while the flexible materials need at least 4 rollers to ensure the normal transportation.
Power conveyor power conveyor is mainly used in high-level logistics automation, and is an important part of logistics automation, mechanization and operation consistency. Power conveyors can be divided into roller conveyors, belt conveyors, chain conveyors and overhead conveyors depending on the driving medium. If the goods have irregular surfaces, such as postal parcels, belt conveyors can be used; goods with regular shapes, such as cartons, pallets, roller conveyors and chain conveyors can be used; but if the spacing and precise positioning of the goods are controlled, Belt conveyors are used; for heavy goods, roller conveyors should be used; if it is required to save floor space, shorten transportation distance and improve space utilization, hanging conveyors can be used.
1. The chain conveyor chain conveyor is a conveyor that uses a chain as a transmission element and a conveying element. The chain of the conveyor is supported by the guide rails and the goods are conveyed in a supporting manner. The most used conveyor elements are the sliding chain and the rolling chain. Therefore, such conveyors can be classified into two types, a sliding chain type and a rolling chain type, depending on the chain used.
2. Roller conveyor Roller conveyor is a widely used conveyor machine. The roller rotates in an active state, which can strictly control the running state of the article. Accurate, smooth, chain conveyors deliver goods reliably at the specified speed, facilitating automation of the conveying process. The requirements for the cargo support surface are the same as those for the gravity roller conveyor. Due to the relatively high price, roller conveyors are generally used for applications such as accumulation, diversion, confluence and sorting. According to the classification of rotation, the roller conveyor can be divided into three types: belt drive, chain drive and gear transmission.
