Description
Conveying installation having an impact-absorption-5 resistant conveying belt
The invention relates to a conveyor with a conveyor belt comprising a loadbearing-side outer sheet and drive-side outer sheet and, between loadbearing-side 10 outer sheet and drive-side outer sheet at least one further, i.e. additional, layer composed of at least one polymeric material, and also with drums, carrier rollers, and carrier frames, where the conveyor forms a material-conveying upper web with an application site 15 for the material to be conveyed, and a mostly material-free lower web. However, there are also conveyors where the lower web is also loaded. A conveyor of this generic type is described in detail 20 in particular in DE 36 06 129 A, EP 1 187 781 Bl, DE 36 12 765 Al, EP 1 222 126 Bl, DE 43 33 839 B4, WO 2005/023688 Al, EP 0 336 385 Bl, WO 2008/034483 Al, EP 1 053 447 Bl and US 7 178 663 B2.
The loadbearing-side outer sheet and drive-side outer 25 sheet of a conveyor belt as main constituent of a conveyor are mostly composed of a foil or of a woven fabric, or preferably of a rubber mixture, comprising at least one rubber component or one rubber component blend, at least one crosslinking agent or one 30 crosslinking system, comprising a crosslinking agent and an accelerator, and also mostly other mixture ingredients, in particular at least one filler and/or at least one processing aid and/or at least one aging inhibitor and/or at least one plasticizer and/or other 35 additional substances (e.g. fibers, color pigments).
The vulcanization of the rubber mixture gives the conveyor belt the required resilient properties.
8429515_1 (GHMatters) P98471.AU 2 2013258262 24 Nov 2016
These resilient properties particularly of the loadbearing-side outer sheet (loadbearing side) of a conveyor belt serve inter alia for the absorption of 5 the energy of impact of the conveyed goods on the conveyor belt (shock absorption). This shock absorption, i.e. the reduction of the energy of impact, is an essential feature for the lifetime of the conveyor belt, in particular of the loadbearing-side 10 outer sheet.
For the purposes of a further development, it would be advantageous if the present invention would provide a conveyor of which the conveyor belt features a further 15 improvement in respect of reduction of the energy of impact, and in respect of the resultant increased lifetime .
The present invention provides a conveyor with a 20 conveyor belt comprising a loadbearing-side outer sheet and a drive-side outer sheet, and also with drums, carrier rollers, and carrier frames, where the conveyor forms a material-conveying upper web with an application site for the material to be conveyed, and a 25 mostly material-free lower web. Between the loadbearing-side outer sheet (loadbearing side) and the drive-side outer sheet (drive side) of the conveyor belt there is at least one further, i.e. additional, layer, which is composed of a foamed polymer mixture. 30
Surprisingly, it has been found that an additional layer of this type made of a foamed polymer mixture has an advantageous effect on shock absorption without impairing the other properties of the conveyor belt and 35 therefore of the entire conveyor.
On the contrary, the presence of at least one foamed additional layer results in a weight reduction which
8429515_1 (GHMatters) P98471.AU 3 2013258262 24 Nov 2016 has an advantageous effect on costs and on energy consumption.
The expressions polymer mixture and rubber mixture are used synonymously. 5
The invention is in principle suitable for all conveyors and conveyor belts.
Particular mention may be made here of steel cord conveyor belts and woven fabric conveyor belts. Further 10 advantages of the invention are apparent in particular in the case of high-temperature conveyor belts, which can take the form of steel cord conveyor belts or of woven fabric conveyor belts, and which have to convey goods to be conveyed at high temperatures (mostly 15 > 250°C). These belts have hitherto been composed of solid rubber layers, which have significantly increased susceptibility to failure when exposed to the thermal stress mentioned, because of the attendant destruction of the carcass, in particular the woven-fabric carcass. 20 The presence of at least one foamed additional layer of at least one polymeric material here reduces heat transmission and prevents destruction of the adherent rubberization of the skim rubber and of rubber/tension member adhesion, in particular rubber/woven fabric 25 adhesion, the overall effect of this being a significant lifetime increase.
The invention can moreover advantageously be used for specific conveyor belts, for example filter belts, which are known inter alia from DE 42 03 359 A1. 30 Filter belts convey and separate solids and liquids, as is necessary by way of example in the treatment of minerals, ores, chemicals, dyes, foodstuffs, coal, and paper, etc. Here again, good chemical, thermal, and mechanical robustness is required, alongside reduced 35 energy of impact.
8429515_1 (GHMatters) P98471.AU 4 2013258262 24 Nov 2016
The loadbearing-side outer sheet and/or drive-side outer sheet can take the form of foil or woven fabrics. It is preferable that the loadbearing-side outer sheet and drive-side outer sheet are respectively composed of 5 at least one polymeric material. It is preferable that the polymeric material is a rubber selected from the group consisting of natural rubber (NR) and/or butadiene rubber (BR) and/or chloroprene rubber (CR) and/or styrene-butadiene rubber (SBR) and/or nitrile 10 rubber (NBR) and/or butyl rubber (HR) and/or ethylene-propylene rubber (EPM) and/or ethylene-propylene-diene rubber (EPDM) and/or polyacrylate rubber (ACM) and/or epichlorohydrin rubber (ECO) and/or chlorosulfonated polyethylene rubber (CSM) and/or silicone rubber (MVQ) 15 and/or fluororubber (FPM).
The rubbers mentioned can be used here alone or in a blend. CR has hitherto been a particularly important material, featuring high flame resistance, weathering resistance, and aging resistance, in particular for 20 conveyor belts used in underground mining. Use of CR provides, in particular in the case of filter belts, an additional weight saving. Other materials that have achieved relatively high importance in open-cast mining are NR, and also the abovementioned blends 25 (DE 10 2009 043 904 Al). If the loadbearing-side outer sheet and/or drive-side outer sheet is a foil or a woven fabric, the materials mentioned can equally be used here. 30 It is particularly preferable that the foil is based on at least one fluoropolymer. In this case, additional optimized media resistance is ensured.
The two outer sheets can moreover comprise, alongside 35 the rubber component, at least one crosslinking agent or one crosslinking system, comprising a crosslinking agent and an accelerator, and also mostly other mixture
8429515_1 (GHMatters) P98471.AU 5 2013258262 24 Nov 2016 ingredients, in particular at least one filler and/or at least one processing aid and/or at least one aging inhibitor and/or at least one plasticizer and/or other additional substances (e.g. fibers, color pigments) 5
The conveyor belt mostly also has an embedded tension-member system. Tension-member systems used are steel cords running parallel in the longitudinal direction of the conveyor belt. However, the tension-member system 10 can also be a single- or multilayer woven fabric structure, in particular in the form of a woven fabric, preferably composed of cotton and/or polyamide and/or polyester and/or aramid and/or glass and/or basalt and/or steel. The materials mentioned can be used alone 15 or in the form of hybrid tension-member systems composed of at least one of the materials mentioned. A woven polyamide-polyester fabric is of particular importance here. In particular in conjunction with steel cord conveyor belts, a transverse reinforcement 20 system made of synthetic cords, for example of polyamide, in the loadbearing-side outer sheet and/or drive-side outer sheet, is also used in order to prevent splitting; see by way of example also WO 2008/034483 A1. 25
There can moreover also be the following components embedded into the loadbearing-side outer sheet and/or drive-side outer sheet: conductor loops, transponders, barcodes, a polymer matrix with, mixed into the 30 material, detectable particles, or other detectable elements .
The conveyor belt can also have an additional part, for example an impeller part, a guide part, and also edge and sidewall profiles. Additional parts of this type 35 are composed of a polymeric material (elastomer, thermoplastic elastomer, thermoplastic), the bases of these being adhesive-bonded and/or vulcanized to the
8429515_1 (GHMatters) P98471.AU 6 2013258262 24 Nov 2016 loadbearing-side surface of the resilient conveyor belt.
Other components of a conveyor can be: 5 - deflector rollers or deflector drums - hold-down rollers, in the case of tubular conveyor-belt systems - correction rollers, in particular in the case of tubular conveyor-belt systems 10 - chutes at the application site for the material to be conveyed - monitoring equipment.
It is essential to the invention that the conveyor belt 15 comprises, between the two outer sheets, at least one further, i.e. additional, layer made of at least one polymeric material, this layer being composed of a foamed polymer mixture.
The qualitative and/or quantitative composition of the 20 foamed polymer mixture here, other than the blowing agents required, can be the same as or different from the compositions of loadbearing-side outer layer and/or drive-side outer layer. In one particularly preferred embodiment, the qualitative and/or quantitative, in 25 particular the qualitative, composition, other than the blowing agents required, is the same as the composition of the rubber mixture of loadbearing-side outer layer and/or drive-side outer layer. This avoids increasing complexity in the production process, and other 30 advantages are obtained in respect of time and costs. The rubber for the foamed polymer layer is selected from the group consisting of natural rubber (NR) and/or butadiene rubber (BR) and/or chloroprene rubber (CR) and/or styrene-butadiene rubber (SBR) and/or nitrile 35 rubber (NBR) and/or butyl rubber (HR) and/or ethylene-propylene rubber (EPM) and/or ethylene-propylene-diene rubber (EPDM) and/or polyacrylate rubber (ACM) and/or
8429515_1 (GHMatters) P98471.AU 7 2013258262 24 Nov 2016 polyurethane (PU) and/or epichlorohydrin rubber (ECO) and/or chlorosulfonated polyethylene rubber (CSM) and/or silicone rubber (MVQ) and/or fluororubber (FPM). The use of CR provides an additional weight saving in 5 particular in the case of filter belts.
The rubbers mentioned can be used here alone or in a blend. The foamed polymer layer can moreover comprise the usual quantities of at least one filler. Any of the 10 fillers known to the person skilled in the art can be used here, for example silica, carbon black, mica, carbon nanotubes, silicates, aluminum hydroxide, talc, chalk, etc.
It is moreover possible to use any of the other 15 additional substances known to the person skilled in the art, for example pigments, plasticizers, antiozonants, and aging inhibitors. The vulcanization of the foamed layer is generally achieved by using peroxide, e.g. when EPDM is used as rubber component, 20 or else in the form of sulfur vulcanization when NR, BR, or SBR is used, or else by using bisphenol when, by way of example, FPM is used.
The foamed polymer layer also comprises at least one blowing agent. The expression blowing agents is usually 25 used to mean pore-forming blowing gases, e.g. azo and diazo compounds, which eliminate gases (e.g. N2 or CO2) on exposure to heat or to catalysts, and which therefore serve for the production of foamed polymer mixtures. The blowing agents decompose here at a 30 particular temperature during processing with formation of gas or in the case of addition of volatile solvents during polymerization or vulcanization. The foaming then takes place either on discharge from the extrusion die, i.e. via vulcanization in a UHF (microwave) hot-35 air system, or injection molding, or in open molds.
It has been found to be preferable to use blowing agents, in particular blowing agents based on at least
8429515_1 (GHMatters) P98471.AU - 8 - 2013258262 24 Nov 2016 one acrylonitrile polymer, obtainable inter alia with trademark Expancel®.
It is also possible if necessary to add foam stabilizers . 5 The invention will now be illustrated by taking an embodiment with reference to diagrams. The invention is not restricted to the drawings shown.
