Roller conveyors

Flow racks are similar to drive-through racks in that they are loaded from one end and unloaded from the opposite end. However, the truck does not enter the rack. Rather, each lane in the rack is equipped with a conveyor (roller, wheel, or belt, depending on pallet characteristics) which both supports the pallet and transports it (by... [Pg.1979]

Hence, several types of equipment can be used to move materials, such as conveyors, rollers, self-powered monorails, carts, forklift trucks, and various devices and manipulators. Automated guided vehicles (AGV) are used extensively as they have high flexibility and they are capable of random delivery to different workstations. AGV are guided automatically along defined pathways, and their routing can be controlled so that the system optimizes the movement of materials and parts in case of congestion, machine breakdown, etc. [Pg.833]

Roller Conveyors Roller conveyors consist of a series of rollers positioned with their axes perpendicular to the direction of movement (Fig. 5). The movement is obtained by the friction generated by the rotation of the rollers powered by electric motors. The parts to be moved must present a flat bottom surface with a size able to cover a distance equal at least of three or four adjacent rollers. In some cases, and for short paths, the movement can be obtained by gravity, using slightly inclined paths (3-5 %) and unpowered rollers, free of rotating. [Pg.847]

Conveyors are used to carry a flow of goods or materials, and can present a number of hazards. There are two broad types of conveyor roller conveyors and belt conveyors. A common hazard is that of trapping, either between adjacent rollers or under the belt. [Pg.224]

ASME B29.4 double-pitch conveyor roller chain, with small diameter rollers, shown with A-2 attachments in Figure 2-11. [Pg.24]

The ASME B29.4 series of double-pitch conveyor roller chains, with either small or large diameter rollers, have the same pin and bushing diameters as the ASME B29.1 standard series chains, but have straight-edged link plates of twice the pitch. [Pg.24]

Many standard attachments are available for conveyor roller chains and those are listed in the ASME standards B29.1 and B29.4. Many more special attachments are made for conveyor roller chains and those may be found in manufacturers catalogs. [Pg.25]

Double-pitch conveyor roller chains are often preferred for conveyor service because of lighter weight and lower eost. A further advantage is that the longer pitch provides space for the large diameter carrier-type rollers shown in Figure 2-12. [Pg.25]

FIGURE 2-20 Straight sidebar engineering steel conveyor roller chain with flanged rollers and K-2 attachments. [Pg.31]

Large-diameter conveyor rollers are not subjected to large impaet forces because conveyor chains run at much slower speeds than drive chains. Thus large-diameter conveyor rollers may be somewhat harder, with less impact resistance, than small-diameter rollers for drive chains. [Pg.59]

Rollers must be strong enough to withstand these forces without distorting or breaking, and rollers must be hard enough to resist wear from engaging the sprocket teeth. Conveyor rollers are... [Pg.75]

Usually the ends are welded to the die-formed sections of apron conveyor pans. Chain attachments are specifically chosen to allow the apron flights to be easily mounted. EingineCTing steel conveyor roller chains are mostly used for apron conveyors. However, some steel bushed rollerless chain with outboard rollers is used on heavy-duty conveyors. [Pg.241]

Double-pitch conveyor roller chains are also used in conveyors. These chains, and standard attachments for them, are hsted in ASME B29.4. Double-pitch conveyor roller chains have straight-edged link plates and come with either small- or large-diameter rollCTs. Chains with small-diameter rollers are normally used in vertical conveyors or short conveyors where the chain slides on the edges of the hnk plates. Chains with large-diameter rollers are normally used in longer conveyors where it is important to reduce the drag caused by friction. [Pg.271]

Standard conveyor roller chains do not work very well in very abrasive conditions. Special conveyor chains designed to keep abrasive matmal out of the bearing areas usually work much better. Consult an ACA roller chain manufacturer for help with selecting a chain for use in abrasive conditions. [Pg.279]

STRESSES, SLIP AND ABRASION OF RUBBER COVERED CONVEYOR ROLLERS A REVIEW... [Pg.52]

Aspects of pressure, shear stress, friction and abrasion in mbber covered conveyor rollers are reviewed. A model is presented for predicting the effect of belt pressure on the deformation of the lagging, and equations are developed for predicting stresses, slip and abrasion. Experimental results are compared with theoretical predictions. Guidelines are given for the design of rollers with longer service life. 111 refs. [Pg.52]
