【正文】 gravity feeds when possible. You can substitute gravity for power conveyor in the right situation, creating both equipment cost reductions and energy savings. Mixing power and gravity units to conserve energy and reduce costs is usually possible.Design with energy savings in mind. Use long, straight runs with fewer drives. If possible, power the entire system with one drive. Use highefficiency speed reducers. Replace wornout conveyor. Modern conveyors designed more efficiently, with appropriate controls, deliver significant returnon investment based on energy savings alone.(5) Correctly select and integrate vertical and horizontal conveyorsWhen elevation changes are necessary, choosing the right vertical transport device can make or break system performance. You have to take into account system throughput requirements, product characteristics, elevation change, number of charge/discharge points, manual or automated charge/discharge, interface with horizontal transport devices, proximity to workers, safety devices, environment, and future system requirements. Analysis of the above criteria will result in an optimum solution. In the unit handling world of a typical distribution center, examples might include vertical reciprocating conveyors (VRC), continuous vertical conveyors, incline belt conveyors, spiral conveyors, chutes, and scissor lifts.(6) Test for performance You have installed a new conveyor system, and you are ready to get into production. Not so fast. It may be tempting to turn your system loose, but you be money ahead if you allow time for adequate testing. If you do a cursory checkout, you miss the opportunity to finetune controls and detect hidden mechanical issues. Conveyor systems can have millions of moving parts designed to work in concert. Due to that plexity, a new system may need adjustments to perform. An outline of testing procedures: Inspection: Visually inspect the entire system. This is about safety. Are all the guards in place? Are the pullstops accessible? Are the safety stickers easy to see and read? The mechanical and junction boxes should be closed. Function testing: Place a small number of items on the conveyor from the various infeed points. This small amount allows for a controlled evaluation process. Look for obvious flaws。 Those in general material handling such as those moving boxes along inside a factory and bulk material handling such as those used to transport industrial and agricultural materials, such as grain, coal, ores, etc. generally in outdoor locations. Generally panies providing general material handling type belt conveyors do not provide the conveyors for bulk material handling. In addition there are a number of mercial applications of belt conveyors such as those in grocery stores.The belt consists of one or more layers of material they can be made out of rubber. Many belts in general material handling have two layers. An under layer of material to provide linear strength and shape called a carcass and an over layer called the cover. The carcass is often a cotton or plastic web or mesh. The cover is often various rubber or plastic pounds specified by use of the belt. Covers can be made from more exotic materials for unusual applications such as silicone for heat or gum rubber when traction is essential.Material flowing over the belt may be weighed in transit using a belt weight. Belts with regularly spaced partitions, known as elevator belts, are used for transporting loose materials up steep inclines. Belt Conveyors are used in selfunloading bulk freighters and in live bottom trucks. Conveyor technology is also used in conveyor transport such as moving sidewalks or escalators, as well as on many manufacturing assembly lines. Stores often have conveyor belts at the checkout counter to move shopping items. Ski areas also use conveyor belts to transport skiers up the hill. A wide variety of related conveying machines are available, different as regards principle of operation, means and direction of conveyance, including screw conveyors, vibrating conveyors, pneumatic conveyors, the moving floor system, which uses reciprocating slats to move cargo, and roller conveyor system, which uses a series of powered rollers to convey boxes or pallets.The longest belt [conveyor system] in the world is in Western Sahara. It is 100 km long, from the phosphate mines of Bu Cr to the coast south of ElAaiun. The longest single belt conveyor runs from Meghalaya in India to Sylhet in Bangladesh. It is 17 miles long and conveys limestone and shale. The Conveyor belt was manufactured in about 300 meter lengths and was joined together and installed on the conveyor at site. The job was carried out by NILOS India Pvt. Ltd. in Chennai Indian .The Idlers or Rollers for this very special Conveyor was produced and supplied by Kali BMH Systems (P) Ltd, Kumbakonam, India. The Idler Rollers were unique for the project that they were designed to acmodate both Horizontal and Vertical Curves along the terrain.Conveyors are used as ponents in automated distribution and warehousing. In bination with puter controlled pallet handling equipment this allows for more efficient retail, wholesale, and manufacturing distribution. It is considered a labor saving system that allows large volumes to move rapidly through a process, allowing panies to ship or receive higher volumes with smaller storage space and with less labor expense.10 Ways to Optimize Conveyor Operations and Productivity(1) Keep your ax sharp maintain your conveyorThere is an old story about a treecutting contest that you should know if you are running a conveyor operation. The contest was to cut the most wood in a one day. One lumberjack relentlessly swung his axe, working as fast as he could. The other stopped to sharpen his ax every hour and despite the downtime, he won. To avoid breakdowns and optimize performance, conveyor needs to be sharp ,as well. Since conveyor downtime
