Description
1 The present invention relates -to a conveyor belt comprising angled entraining bars, commonly referred to in the art as "cleats", ~or vertlcally conveying b~lk or loose material at a steep angle, and comprising corrugated side walls and cleats o~ elastomeric material aligned transversely thereto and arranged at substantial]y equal 1 mutual longitudinal spacings which in each instance have ! a foot or base secured to the conveyor belt and/or are laterally secured to the crests of the ccrrugations of the corrugated side walls of the conveying space, and which in each case in cross-æection incorporate a first straight lower branch approximately perpendicular to the conveyor belt plane and a second straight branch in continuation of the first and which is inclined with respect thereto.
An earlier conveyor belt of this kind has cleats located between the lateral corrugated margînal bars (corrugated sides~ and having an angular cross-section which are in each case formed by two straight branches, in cross~section. Of theseg a lo~er one ex-tends approx-imately at right angles to the conveyor belt~ whereas the æcond upper branch is inclined with respect to the first branch. The height of the cleats measured at right angles to the conveyor belt plane corresponds approY~imately to the height of the corrugated sides. The conveyor belt is installed in such manner that the sloping second branches of the cleats point in the upward direction of the conveying path. The lateral corrugated sides and the cleats between them delimit individual "boxes" for reception of the loose material which is to be conveyed.
The conveyor belt is normally charged or loaded in a horizontally extending section. In the steeply angled or vertical conveying section, the second inclined branches of the cleats prevent the loose material dropping sideways out of the "boxes". The conveying capacity of ~`
,~
1 the conveyor belt depends, ~yar-t from -the conveyor bolt speed which cannot be increascd at wlll, on the mutual longitudinal spacirlg of the clea-ts, that is the number of cleats per unit of length, and on the quantity of loose m~terial which can be retained in the steep or vertical conveying section by each indi~idual cleat -obviously in conjunction wi-th the lateral corrugated sides. Limits are imposed in this case on the conveyor belt ~described, with its singly angled cleats.
It is an object of the invention to provide a conveyor belt of the ~ind hereinabove referred to but whose conveying capacity is increased in an ~ncomplicated manner.
Accordingly the invention consists in a conveyor belt for vertical conveying loose material at a steep angle, comprising corrugated side walls and cleats of elasto- .
meric material aligned transversely thereto and arranged at substantially equal mutual longitudinal spacings, which in each case have a foot or base secured to the conveyor belt and/or ~a~erally secured to the crests of the corrugations of the corrugated side walls of the conveying space, and which in each case in cross-section incorporate a first lower straight branch approximately perpendicular to the conveyor belt plane and a second straight branch in continua-tion of the.first and which is inclined with respect thereto, wherein said second branch of each cleat is followed by a straight third branch which, in cross-section; is inclined with respect to said second branch in the same direction as the latter is inc~ned with respect to said first ~ranch and has a shorter length than said second branch, said second branch subtending an angle within the range of 40 - 65 with the plane of the conveyor belt and sa~id third branch subtending an angle within the range of 28 - 53 with the plane of the conveyor belt~ and wherein the length of ~ t~
l sa;d secolld brarlcll amounts to ~5~0 - 7~,0 of -the l~ngth of said firs-t branch, arld -the length of said third branch amoun-ts to 23'io ~ ~7'Jo o:f -th~ length ol said first branch.
~ conveyor belt according to the invention has cleats which are angled twicc in cross-section under retention of a particul~r cross-sectional shape deter-mined by the angles of lnclination and relative lengths of the three branches of each cleat. This construction enables a particularly great conveying capacity of the conveyor belt to be obtained in two respects, firstly each cleat by i-tself can hold a very large volume of loose material in -the steep or vertical conveying section due to its cross-sectional shape, and secondly, the mutual longitudinal spacing of the cleats on the conveyor belt may be reduced distinctly as compared to earlier constructions, without impairing the loadability of the conveyor belt in the horizontal charging section. A very pronounced slope of the cleats in the upward direction would inhe~ntly increase the reception volume of each individual cleat, but would simultaneously reduce the aperture width of the individual "boxes" in the longi-tudinal direction of the conveyor belt and thereby impair adequate filling of the individual conveying boxes in the horizontal charging section, which would then again have to be balanced by an increase of the longitudinal spacing and thereby a reduction of the overall conveying volume. An excellent compromise between these two opposed parameters influencing the conveying capacity is realised by means of the cleats of particular cross-sectional shape, in the case of a conveyor belt accordingto the invention. ~urthermore, cleats of the inventive conveyor belt have a high degree of morphological stability because of their shape, so that they may also be constructed with a compar~tively great height of 400 mm for example, which evidently also benefits the conveying t)'7 1 c~p~city.
The conveying capacity of the inventive conveyor belt reaches an optimum lf the mutual longitudinal spacing of the cleats amounts to 60 to 10~/o of their ver-tical height. The quantity o~ loose material which may still be loaded in controllable manner into the space between two consecutive cleats, that is into a "box", even at the quite high conveyor belt speeds of for example 3 ms -1 which have become customary nowadays, then corresponds very largely to the reception volume of the individual cleat in the vertical conveying path section. In particular, the choice of -the longitudinal spacing clearly depends on the nature of the loose material, in particular on its granulometry and heaping angle.
In the case of large grain size, but also in that of a great heap apex angle - because it leads to a higher reception capacity of the indivîdual cleat - the longitudinal spacing will be preferably Ghosen at the upper end of the range specified.
In cross-section each cleat may ha~e a curvature at the junctions between the first and second branches and between the second and third branches, and has an increased wall thickness in the area of the curvatures.
This construction gives the cleats a particularly great morphological stability and at the same time improves the delivery of ma-terial at the cleats by virtue of the curvatures. The morphological stability may be raised even more by means of reinforcing webs formed on each cleat in the obtuse angle'between the first branch and the second branch. Two inserts in each cleat may also be used to reinforce ~he same and thereby improve its durability, the inserts preferably consisting of steel cords.
In order that the invention may be more clearly understood; reference will now be made to the accompanying -6- ~ 2~ ~
1 drawings which show one embodiment thereof by way of exa~ple and in which:-~ igure 1 shows an isometric view of an excislonfrom a conveyor belt for steep and vertic~l conveying of loose material, ~ igure 2 shows a cross section through -the conveyor belt according to Figure l, and Figure 3 shows a longitudinal cross-sec-tion through the conveyor belt according to ~igure 1.
Referring now to the drawings according to ~igures 1 and 2, a conveyor belt l of rubber or analogous ma~terial and of conventional structure has each of its two edges occupied by a corruga-ted marginal bar of rubber or the like, constituting a corrugated side 2, which edges protrude at approximately right angles. Cleats 5 of rubber or the like aligned transversely to -the longi-tudinal. direction of the conveyor belt, which subdivide the space between the corrugated sides into separate conveying boxes are fitted at substantially equal mutual . 20 longitudinal dlstances on the conveyor belt (see Figure 3). Each cleat 5 has a wide approximately T-shaped foot or base 6 which is formed by two angular base bars 6a and 6b. The pair of base bars 6a,6b is firmly jolned to the conveyor belt 1 by bonding. The ac-tual cleats are connected to the pair of base bars 6a 7 6b by means of screws 8 so that they may be replaced if need be.
Each cleat 5 has a double-curvature cross-section comprising three straight branches 10, 11 and 12.
first lower branch lO is joined to the foot or base 6 and extends approximately at right angles to the plane of the conveyor belt l. A second middle branch 11 is inclined in the longitudinal direction of the conveyor belt with respect to the firs-t branch and subtends an angle of approxima~tely 53 w.ith the conveyor bel-t plane.
~ ~626~
1 A -third u~per branch 12 .is :inc~lined even more in the same direc-tiorl as the second branch and subtends an angle of approximately 41 with the conveyor bel-t plane.
The lengths of the second and third branches 11 and 12 respectively, measured in cross-section, amount -to approximately 57% and 35~o respectively of the length of the first branch. The height of each cleat measured at ri~ht angles between the conveyor belt plane and the free extremity of the third branch 12 is approxi~ately 10 8% smaller than the height of the corrugated sides 2, so that the cle~ts may rise a little under load without at the same time projecting above the corrugated sides.
The mutual longitudinal spacing of the cleats 5 amounts to approximately 68~o of their heightA Typical dimensions are a corrugated side height of 400 mm and a mutual longitudinal spacing of the cleats 5 of approximately 250 m~.
~ ach cleat is so arranged on the actual conveyor belt 1 that it has the lower perpendicular branch 10 positioned precisely between two mutually opposed and inwardly facing crests 15 of the corrugations of the two corrugated sides 2. In addition to the fas~ening to the foot or base 6, it is laterally secured to these crests 15 by means of bolts 16 which are anchored in the lower branch 10 of the cleat 5 and.bol-ted to the corrugated sides.
Three reinforcing webs ~8 extending at right angles to the actual cleat are formed on each cleat 5 in the obtuse angle between the lower ~irst branch 10 and the middle second branch 11, whereby the bending strength of the cleats 5 is increased. Two areal inserts 19 of steel cords which as seen in cross-section are embedded in each cleat wlth Mutual spacing and extend throughout from the lower branch 10 up to close ~5 to the free extremity of the upper branch 12 fulfil 1 the sarne purpos~
~ t the -transi,tions from the :first to the second and from the second to the third branches, each clea-t 5 has curvatures 20 and 21 respectively. Furthermore~ the clea-ts have an increased wall thickness in the area of the curvatures which equally distinctly improves the morphological stability.
The theoretical reception volume of each separate cleat is proporti~ al to the area, see ~igure 3, which is bounded by the cleat and the conveyor belt as well as by the line 25 or 26, the line 25 being applicable for loose material having a heap apex angle of 10 and the line 26 for loose material having a heap apex angle of 0 - both relating to vertical conveying. A charging aperture is present between adjacent cleats in each case, the width 27 of which determines the loadability of the conveyor belt and of its individual conveying boxes.
In the case of the inven-tive conveyor belt, the cross-sectional shape or form of the cleats is optimised in such manner that a great reception volume of each cleat is the result on the one hand, but that on the other hand the width 27 of the charging aperture is adequa,te despite comparatively small longitudinal spacings of the cleats to allow of full utilisation o~' the reception volume of the cleats by appropriate charging.
An earlier conveyor belt of this kind has cleats located between the lateral corrugated margînal bars (corrugated sides~ and having an angular cross-section which are in each case formed by two straight branches, in cross~section. Of theseg a lo~er one ex-tends approx-imately at right angles to the conveyor belt~ whereas the æcond upper branch is inclined with respect to the first branch. The height of the cleats measured at right angles to the conveyor belt plane corresponds approY~imately to the height of the corrugated sides. The conveyor belt is installed in such manner that the sloping second branches of the cleats point in the upward direction of the conveying path. The lateral corrugated sides and the cleats between them delimit individual "boxes" for reception of the loose material which is to be conveyed.
The conveyor belt is normally charged or loaded in a horizontally extending section. In the steeply angled or vertical conveying section, the second inclined branches of the cleats prevent the loose material dropping sideways out of the "boxes". The conveying capacity of ~`
