Abstract
The invention concerns a mono or twin-rail overhead chain conveyor (10', 12'), in particular for transporting heavy loads such as motor vehicle parts. The conveyor has a chain track (14) in the form of an I-shaped profile with running gear (18, 20) which can move along said track and has roller blocks (26, 28) for mounting rollers (30, 32) which are supported on the chain track. The roller blocks are connected to a traction means (42) for pulling the running gear. For a monorail overhead chain conveyor, the running gear is in the form of loading running gear and, for a twin-rail overhead chain conveyor, it is in the form of towing running gear which interacts with loading running gear (82) movable on a load rail (78) running below the chain track. In order to render wear-free, silent running possible, the traction means (42) is a rubber or plastics belt having a single-stranded metal, glass fibre or carbon fibre insert (46)
Description

In addition to the classic mono - ortwin - rail overhead chain conveyors, as illustrated and described in-for example-"Lueger Lexikon der Technik, Fordertechnik und Fabrikorganisation Vol. 1, p. 246 ff., published by Rowohlt Taschenbuch Verlag GmbH, Germany, a large number of suspension conveying devices are known with design features that can differ from those described at the outset. For example, in a hanger- type conveyor according to DE-AS l 230 354, a pulling belt running on edge is used, in which several pulling ropes parallel in the longitudinal direction are vulcanized in. A corresponding hanger - type conveying system is however suitable exclusively for use in a horizontal plane, since otherwise a tensile strain would be exerted on the pulling ropes arranged one above the other that varies widely enough to break these ropes.
Suspension devices intended for the transportation of garment products are described in DE 40 17 821 Al and DE 35 10 195 Al. Here a drive belt can interact with driving dogs of supporting brackets to move the latter along a guide track formed by a square section. Specially designed plastic rails are required for guidance of the drive frame.
In the case of load carriers according to DE 41 21 772 Al, DE 27 40 594 Al, US
26,78,718, US 2,980,958 or DE 25 45 676 Al, chain links are used that are drivable using friction wheels, for example. The chain links can be connected at their connection points to towing running gear.
The object underlying the present invention is to develop a mono - or twin - rail overhead chain conveyor of the type mentioned above such that an almost maintenance - free traction means can be used that is drivable without problem and which can be guided simply in respect of the route, however without the need fordesign changes to the mono- ortwin-rail overhead chain conveyor at least in respect of the chain track and loading track.
An endless conveyor is known from NL-A-7 914 018 in which a cable sheathed, for example with nylon, as corrosion protection is used as the traction means.
CA 02184987 1998-03-2~
The problem is substantially solved in accordance with the invention in that the traction means a belt comprising a rubber or plastic material a single - stranded insert of metal, glass fiber or carbon fiber. In particular, the belt is a rubber beltwithrectangularcross-section, hlto which is vulcanized a steel insert preferably concentrically to the longitudinal axis of the belt.
By the teachings in accordance with the invention, the drawbacks immanent in known mono - or twin - rail overhead chain conveyors because of the bolt- linked and flat-linked chains used are elimin:~tc-l, without the disadvantages obtained from a mono-or twin - rail overhead chain conveyor being dispensed with.
As a result of the fact that the mono - or twin - rail overhead chain conveyor in accordance with the invention differs from known ones only in that the bolt- linked and flat - linked chain is replaced by the rubber belt having a steel insert, the lubricants required for chains are not necessary. Wear is also prevented that would otherwise occur in the joints of the chain links. It is furthermore advantageous that the mono-or twin - rail overhead chain conveyor operates with little noise.
Nevertheless, tensile forces can be transmitted with the mono- ortwin-rail overhead chain conveyor that are known from bolt- linked and flat- linked chains, since the rubber belt contains the metal insert preferably designed as a steel rope.
Since the insert such as a metal insert is single - stranded and extends in particular coaxially to the longitudinal axis of the belt, ascending and descending sections can be traversed without problem. since the steel insert is always subjected to the same load and hence no differing tensile stresses occur.
The use of a belt permits a higher conveying speed compared with a mono - or twin -rail overhead chain conveyor with the conventional chain.
W09 il75056 2 ~ PCT/EP95/00923 The spced cnn be hlcleased hele by 50 to 100%.
I~urtherlllorc, fewer lensio~ lg stations are necessary, sincc wear on the Iraclion means occurs - as already mentioned - only to a negligible extent. By contrast, the chaill links of a pullhlg chaill are subject to ~v..~ ble wear.
By thc use of a belt comprising plastic and in particular rubber, it is furthcrmore possille lo use it hl tlle food rrocessing hldustry, since lubrication of the traction means is not necessauy, nor docs the traction mcans have poorly accessible areas.
To permit the usc of tlle traction means proposed in accordance witll the invention e-en willlout rundamenial challges to tlle towing runnulg gear and hence to Ille roller blocks, it is pro~ided in a fullller dev~lu~ t of the hlvelltion that the belt has latcral cutouts for .I--u~ lud.~ g roller block sides of the tOWillg running gcar.
The belt itself can have a widtll ~ull~uvn~ g to tbat of a bolt-lhlked or flat-linked chain used in a mollo- or h~in-rail o~erhead chain conveyor. Ilere too, it is emphasized that - witll tlle exception of the traction means - the teachings in accordance witll ~he hl~ention can be employed without design changes to know mono- or twill-lail o~erhead chain convcyors.
In order to permil dli~hlg of the tractioll means, for example by frictional grip, a furtller d.~.lu~ l..lt of the invelllion provides that the bclt runs in rcspcct of its lateral surraces llush or almost nush witll outer-surface sides of the rollcr blocks, so that tllo la~er do not impair ~he drive action.
If as a result of a fault the rubber or plastic belt is brokell, a repair can be effected hl shllple fashioll by exposhlg tlle metal inserts of the belt ends and connecting them using clamphlg elements to a wire rope rumling parallel to the ends.
~10951~S056 PCT/EP95/00923 ~ 5 2i84987 In accordance v~dth an independent invention proposal, tlle use of a belt comprising a ruobcr Ol plastic material witll steel inselt running coaxially to its central axis as a substitute for a bolt-linked or flat-linked chain of a mono- or twin-rail overhead chain conveyor is envisagcd that comprises a chain track in the foml of an l-shaped profile with running gear movable along the latter and interacting with loading running gear moving on a load rail running below Ihe chain track or itself dcsigned as loading running gear.
In a mono- or tv. hl-l ail overhead chahl conveyor in accordance with the invention the bclt can be guided betv.~een friction wheels used as the drive.
Altemativcly, it is possible for the belt to be guided betweell endless belts v~hich serve as ~hc dri-e. i~inally, it can be providcd that along onc sidc of the belt scveral pressulc rollers arc disposcd in a line, wllile on the opposite sidc and associated with Ihe prcssurc rollcrs an endless drive bclt is providcd. The belt is guided between the drive bclt and thc pressule rollers and is driven by frictional grip.
To form horizontal curves, it is only sullicient that the belt is guided along rollers v~hose axes are on an arc or circular section. Alternatively, the belt can be guided along a section of a rotata'oly mounted disk.
Iiowever, a vertical curve is also Feasible in simple fashion. In this way it is only necessaly tlnat betwcen rum1ing gear units com1ected directly or h~dircctly to a load support spacers arc disposed that extend from the track and are connected to the belt, thereby ensuring that the l~elt follows the route set by the track.

The bearing blocks (26) and (28) run with their lower vertical sections inside a chain Ih~k (38) whose longitudinal sides (40), (42) are shown hatched in Figs. 2 and 9. The outer distance bctweell the sides (40) and (42) is D.
Wilhout diverging from tl1e f, ' I design of the Iwin-lail overhead chain conveyor (10), it is proposcd in accordal1ce wilh the u1vcntion that thc traclion meal1s in the form of thc bolt-linkcd or nat-linked chain bc replaced by a lubber belt (42) prefcrably having a smooth oulcr surface and a metal insert in the form of a wire rope (46) running . ., f ~ lly to the longitudinal axis (44). This does not howcver generally cntail any changes in palticular in the dimcnsions of the palts used in thc twin-rail overl1cad chaill conveyol (10). For tnat reason, the reference numbers used in rigS. 3 and 4 are those aheady used in connection with the twin-rail overheadchain conveyor (10) according lo Figs. I and 2. Thc twin-rail overhead chain conveyor having ihe traction means (42) in accordance witl1 thc invenlion is furtllerl1lore identified with the reference number (10') to stress their similarity.
Instead of tl]c iraction means (24) h1 the form of the bolt-linked or nat-linked chain used according to the prior art, the lubbcr traction means (42) of rectangular cross-section and with ~ulcani~ed wire rope insert (46) is used in accordance with theinventiol1, witl1 the geometric dimensions of the traction means being retained to the extent that the widtll of the belt (42) corresponds lo the outer distance D of the chain Ih1k (3~) enclosing Ihe sides (36) and (38) of Ihe bearing blocks (26) and (28).ror tl1at reason the widlh of the belt (42) is also given as D in Fig. 10.
The heigl1t of the belt (42) is i~ itll Ille height H being preferably slightly smaller thal1 ~he widtl1 D. The ratio of D to El is preferably about 1.2:1.
In order for the bearing blocks 8Z6), (28) or thcir vertical sides (34), (36) not to impair the drivillg action of thc belt (42) by fiictional grip, thc belt has ~wlcai~ulld;.., cutouts to: ' the sides (34), (36), wllere before and behind the sides (34), (36) thc latcral or running surfaccs (58), (50) are fit flush into the lateral surfaces (54), (56~ of Ihe bearing blocks (26), (28).

Sincc a mollo-rail overhead chain conveyor diffcrs from a twin-rail overhead chain conveyor only in that the towing running gcar doubles as loading running gear in thc mono-rail overhcad chaill conveyors (12) and (12 ) of Figs. 5 - 8 have identicalreference numbers to Ihe ~ elements in Figs. I and 4 since as already mentioned the mono-rail overhead chain conveyor (12 ) hl accordance with the invention difrers from tlle prior art only to the extent that the traction means (24) in the rorlll of a bolt-linked chain is also replaced by one witll rectallgular rubber belt (42? witll vulcanized wire ropc insert.
By the use in accordancc with the invention of a rubber belt witll singlc-stranded metal inscrt advalltages accrue not only in respect of low noise operation and reduction of wear . ~ witll a reduction in the number of tensioninf stations but also from the repair in simple fashion of the traction means (42) as is made clear in Fig. 12.

In Ille embodhllellt in Fig. 14, the belt (42) is guided along rollers (74), (76) mounted on an arc or circular section.
To traverse vertical cul~es, it is necessary both for the twin-rail overhead chain conveyor (10') and for the mono-rail overhead chain conveyor (12') that spacers (20) extend to a sufGcient extent fiom thc respcctive tracks (14) between the towing and Ic,ading running gear (18), in order to hold the traction means (42) such Illat it cannot sag or drag on a Irack in ascending or descending sections.
Fig. 16 sho~vs a scction of a twin-rail ovcrhead chain conveyor where underneath the chain track (14) is a loading track (78) along which loading running gear (80) and (82) connccted by a cross-picce (84) can be moved. To do so, pawls (84) extending from the loading running gear (82) interact with the driving dog (22) of the towhlg runlling gcar (18).
Further drive means for the belt (42) are shown in Figs. 17 - 19.
The belt (42) can be clamped between endless drive belts (86), (88) to achieve the necessary frictional grip in this way.
According to thc ~Illbodil-~ in Fig. 18, the belt (42) passes between the endless belt (88) and along a line of friction v~heels (90), (92).
In accordance with the e",l,~ in Fig. 19, friction wheels (98), (100) are disposed along Ihles (94, 96), betwecn which friction wheels the belt (42) is pulled by frictional grip.
In the figures, in which idcntical elemcnts ale as a lule providcd with idcntical reference numbers, sections or detailed view of a mono- or twin-rail overhead chain conveyor are shown that from Illeir general design correspond to cu,-v.,-liu,,.,l . . .
O95/25056 i'CT/FP95/00923 8 21849~7 structules. ror Ihat rcason rigS. 1, 2 and 5, 6 show respectively a twin-rail overhead chain conveyor (10) and a mol-o-rail overhead chain conveyor (12) of standard desig m The tv~ raii ove:head chah1 conveyor (10) showll in section in Fig~ I (Power andFrec convcyol) tllclerole comprises in the normal manllcr a chain lrack (14) in the iorm of an l-shaped profile (16) ~ith runnh~g gear (18) and (20) along this track, said runnillg gear (18) being designed as towing runnhlg gear irom which projects a driving dog (22) that can be gripped by an indicated pawl of loading running gear, not showil, and also movable in loading running gear undcmeatll the chain track and also hl tlle form of an l-shaped profile. The load to be conveyed, such as a bodywork section or other molor vehicle component, is lhell suspendcd irom Ihe loading lunning gear or fiom a cross-piece connecting two successive rulming gear unils.
To move the rulming gear (18), (20), it is provided with a traction means (24) that can bc a bolt-linkcd or flat-linked chain. In the rll,l,olli,.. l. a bolt-linked chain (24) is sllo~
To rule out sagging of the traction means (24), running gear serving as spacers is plovidcd between tov~ing running gear (18) and corresponds to the running gear (20) ill its desigm Regardlcss oi whether the runnh~g gear is a towing running gear or a spacer, therumlhlg gear (18), (20) has bearing blocks (26), (28) ior wheels (30~, (32) that are movable aiong thc chain track (14), i.e. along the l-shaped profilc. (16).
The bearing blocks (26) and (28) run with their lower vertical sections inside a chain Ih~k (38) whose longitudinal sides (40), (42) are shown hatched in Figs. 2 and 9. The outer distance bctweell the sides (40) and (42) is D.
Wilhout diverging from tl1e f, ' I design of the Iwin-lail overhead chain conveyor (10), it is proposcd in accordal1ce wilh the u1vcntion that thc traclion meal1s in the form of thc bolt-linkcd or nat-linked chain bc replaced by a lubber belt (42) prefcrably having a smooth oulcr surface and a metal insert in the form of a wire rope (46) running . ., f ~ lly to the longitudinal axis (44). This does not howcver generally cntail any changes in palticular in the dimcnsions of the palts used in thc twin-rail overl1cad chaill conveyol (10). For tnat reason, the reference numbers used in rigS. 3 and 4 are those aheady used in connection with the twin-rail overheadchain conveyor (10) according lo Figs. I and 2. Thc twin-rail overhead chain conveyor having ihe traction means (42) in accordance witl1 thc invenlion is furtllerl1lore identified with the reference number (10') to stress their similarity.
Instead of tl]c iraction means (24) h1 the form of the bolt-linked or nat-linked chain used according to the prior art, the lubbcr traction means (42) of rectangular cross-section and with ~ulcani~ed wire rope insert (46) is used in accordance with theinventiol1, witl1 the geometric dimensions of the traction means being retained to the extent that the widtll of the belt (42) corresponds lo the outer distance D of the chain Ih1k (3~) enclosing Ihe sides (36) and (38) of Ihe bearing blocks (26) and (28).ror tl1at reason the widlh of the belt (42) is also given as D in Fig. 10.
The heigl1t of the belt (42) is i~ itll Ille height H being preferably slightly smaller thal1 ~he widtl1 D. The ratio of D to El is preferably about 1.2:1.
In order for the bearing blocks 8Z6), (28) or thcir vertical sides (34), (36) not to impair the drivillg action of thc belt (42) by fiictional grip, thc belt has ~wlcai~ulld;.., cutouts to: ' the sides (34), (36), wllere before and behind the sides (34), (36) thc latcral or running surfaccs (58), (50) are fit flush into the lateral surfaces (54), (56~ of Ihe bearing blocks (26), (28). For that rcason the distance of the lateral surfaces ~54), (56) is also idcntifed as D in Fig. I l.
~ 1095/~5056 rCT/EP95/00923 ~ ,o 2184987 To connect the r unning gear (18) (20) to the belt (42) ~OIl~al)ullL!lg cutouts can be providcd in Ihe belt (42) at the place of assembly of the twin-rail ovcrhead chain conveyor (10 ) This has the advantage Ihat a running gear unit can be positioned at evely lequired position which is an option not open wllen the traction means is a bolt-linked or nat-linked chain since the running gear has to be aligned wilh the chain Ihlks.
Sincc a mollo-rail overhead chain conveyor diffcrs from a twin-rail overhead chain conveyor only in that the towing running gcar doubles as loading running gear in thc mono-rail overhcad chaill conveyors (12) and (12 ) of Figs. 5 - 8 have identicalreference numbers to Ihe ~ elements in Figs. I and 4 since as already mentioned the mono-rail overhead chain conveyor (12 ) hl accordance with the invention difrers from tlle prior art only to the extent that the traction means (24) in the rorlll of a bolt-linked chain is also replaced by one witll rectallgular rubber belt (42? witll vulcanized wire ropc insert.
By the use in accordancc with the invention of a rubber belt witll singlc-stranded metal inscrt advalltages accrue not only in respect of low noise operation and reduction of wear . ~ witll a reduction in the number of tensioninf stations but also from the repair in simple fashion of the traction means (42) as is made clear in Fig. 12.
To connect separatcd sections (58) aod (60) of the traction means (62) a wirc rope 14G) is exposed at the ends thcn pcrmitth~g the free ends (62 (64) to be connectcd by clamps or clips (66) (68) to a wire rope section (70) running parallel to the free ends (62) (64) To drive the belt (42) it can be guided between friction wheels in contact with the runninC surfaces (48) (50) such that the belt (42) can be pulled simply along the track (14) To pel-mit the belt (42) to traverse a horizontal curve there are various ~~'O95/'50~6 : : PCT/EP95/00923 Il 2 1 84~87 possibilities as shown in lhe ~mbo~ ...lL~ in Fig. 13 and 14. For example, in the d;l,l. .a in Fig. 13 Ille belt (42) is guided along a seclion of a rotatably mounlcd disk (72).
In Ille embodhllellt in Fig. 14, the belt (42) is guided along rollers (74), (76) mounted on an arc or circular section.
To traverse vertical cul~es, it is necessary both for the twin-rail overhead chain conveyor (10') and for the mono-rail overhead chain conveyor (12') that spacers (20) extend to a sufGcient extent fiom thc respcctive tracks (14) between the towing and Ic,ading running gear (18), in order to hold the traction means (42) such Illat it cannot sag or drag on a Irack in ascending or descending sections.
Fig. 16 sho~vs a scction of a twin-rail ovcrhead chain conveyor where underneath the chain track (14) is a loading track (78) along which loading running gear (80) and (82) connccted by a cross-picce (84) can be moved. To do so, pawls (84) extending from the loading running gear (82) interact with the driving dog (22) of the towhlg runlling gcar (18).
Further drive means for the belt (42) are shown in Figs. 17 - 19.
The belt (42) can be clamped between endless drive belts (86), (88) to achieve the necessary frictional grip in this way.
According to thc ~Illbodil-~ in Fig. 18, the belt (42) passes between the endless belt (88) and along a line of friction v~heels (90), (92).
In accordance with the e",l,~ in Fig. 19, friction wheels (98), (100) are disposed along Ihles (94, 96), betwecn which friction wheels the belt (42) is pulled by frictional grip.
