EN ISO 21183-1:2006 (E) 2 1 Scope This part of ISO 21183 describes the principal characteristics and applications of li
16、ght conveyor belts. This description is necessary either for limiting the validity of certain standards to light conveyor belts or for excluding light conveyor belts from the validity of certain standards. 2 Description 2.1 Applications 2.1.1 General applications Light conveyor belts are predominant
17、ly used for the indoor transport of unit loads (for example, parcels, boxes, cans, containers, luggage, industrial goods of all kinds and foodstuffs). In many cases, light conveyor belts are incorporated into a machine as an integral machine element. They are then called machine belts (also known as
18、 machine tapes). In that function, they perform either just as a conveying element that additionally participates in a manufacturing action or in a manufacturing process. In such applications, machine belts sometimes get special names. EXAMPLE 1 Machines using machine belts with a pure conveying fun
19、ction: paper processing machinery (printing, cutting, etc.), letter sorting/cancelling machines, ticket vending/defacing automats, packaging machines. EXAMPLE 2 Machines using machine belts participating in a manufacturing action or in a manufacturing process: newspaper folding machines, processing
20、machinery for dough, chocolate and sweets, special processing machines for paper and plastic foil, cigarette manufacturing machines. EXAMPLE 3 Machine belts with special names: folder-gluer belts, tube-winder belts, printing blankets; processing belts in drying, coating, par ticle board manufacturin
21、g and other uses. 2.1.2 Other applications Bulk foods conveying with light conveyor belts can be found in the chemical, pharmaceutical, cosmetic, food, agricultural, wood and tobacco industry. However they are almost always in indoor applications or outdoors under cover. EXAMPLE Granular or powdered
22、 materials, corn, rice, fruits, vegetables, wood chips, tobacco. Outdoor applications of light conveyor belts are seldom encountered but are increasing for example, agricultural equipment, particularly some harvesting machines. EN ISO 21183-1:2006 (E) 3 2.2 Construction The tensile strength of light
23、 conveyor belts is normally provided by mainly synthetic fabric plies (polyamide, polyester, etc.) connected with each other either by bonding agents or by means of intermediate layers of different thickness, usually of thermoplastic material. The covers on both sides are function-related in materia
24、l, thickness and texture. All combinations are possible, from no coating via thin impregnation to thick coating and from ultra smooth to very rough surface. Coating materials may be thermoplasts (PVC, TPU, etc.), cross-linked synthetics (rubbers, PUR, etc.) and many others, all in very different har
25、dness and other varieties of formulation. Highly specialized constructions are found with machine belts very elastic belts, monolithic foils, surfaces with very high or low friction characteristics, etc. 2.3 Dimensions Light conveyor belts are almost exclusively manufactured in large widths (up to a
26、 few metres) and then are cut to any required dimension. The dimensions of light conveyor belts are not standardized. Standardization would not be suitable as the light conveyor belts are predominantly used on non-standardized installations. The overall thicknesses vary from a few tenths of a millim
27、etre to several millimetres, depending on the specific application (e.g. 10 mm or more in the case of light conveyor belts for the paper processing industry). The widths vary from about 10 mm (machine belts) to a few metres (processing belts). The lengths vary from about 500 mm to about 100 m. 2.4 P
28、roperties The ultimate tensile strengths vary from less than 100 N/mm of belt width to several hundred newtons per millimetre of belt width (e.g. to about 1 000 N/mm of belt width in highly specialized belt constructions with aramid fabrics). The maximum admissible working load is about 1/10 of the
29、ultimate tensile strength. As mentioned in 2.2, the properties vary within a broad range and are function-related and, in the case of many types, are designed to meet highly specific application demands. EXAMPLE 1 Special light conveyor belts for the electronics industry have highly conductive cover
30、s with very small electric surface resistances and produce no measurable electric field strength when running. These light conveyor belts are highly antistatic. EXAMPLE 2 Normal light conveyor belt covers are mostly insulators which usually generate high electric field strengths. Nevertheless, with some belts, no significant electric field strength is produced when the belt is running because of an electrically conductive layer inside the belt. These belts are antistatic in the sense of light conveyor belt technology. EN ISO 21183-1:2006 (E) 4
