All About Roller Conveyors - Types, Design, and Uses

Simply put, roller conveyors are a form of conveyor belt that utilizes rollers - evenly-spaced rotating cylinders - to allow objects to skate across its surface. They move material from one place to another destination, and often leverage gravity or implement small motors to do so. The transported material must have a rigid riding surface that is supported by a minimum of three of the rollers ...

An Introduction to Conveyor Fundamentals

roller conveyor; however, the difference is that instead of using a drive pulley to move the conveying surface, each roller is powered to rotate, thus moving the material. Roller rotation is generated either by a conveyor belt (Figure 7) riding underneath the rollers, or by each roller being driven by its own drive belt. Figure 7. Live Roller Conveyor. Live roller conveyors are relatively ...

Structure Design of the New Roller Conveyor Scientific.Net

Based on the basic theory of three-phase AC Linear Induction Motor (LIM), this paper has designed a new structure of the roller conveyor. The device mainly consists of three parts, such as rollers, LIM and control-power unit. The roller serves not only as driving and load-bearing mechanism, but also as the secondary structure of LIM. The new roller conveyor is a new structure form of the ...

Understanding Conveyor Systems - Types, Applications

24/03/2021  Live roller conveyors can be furnished with pop-out rollers that disengage from their drive belts if a person’s hand or foot slips between rollers. Crossovers can be used to permit people to pass over long sections of belt conveyors. Roller style conveyors often use manual or powered gate sections to accomplish this. Conveyors often incorporate some type of soft starter or clutch mechanism ...

Conveyor rollers driven by grooves are basically designed to be antistatic. The charge is conducted with low ohm resistance from the tube to the shaft by means of an antistatic element. The profile opening, into which the roller is laid or screwed, has to have uncoated surfaces in order to conduct the charge without sparking into the earthed side profile. This is the responsibility of the ...

Belt Tracking - hdg-enterprises

Conveyor bed sections (slider or roller) must be properly aligned with no vertical off-set between sections. A taut line should be stretched over the top surface of the bed and adjustments made so that all points are in contact. The entire bed (and each section) must be horizontal (across the width). If they are not, the belt will be pulled by gravity and will “drift” toward the low side ...
