Abstract
Abstract An installation for assembling and/or machining parts manually and/or automatically, the installation comprising a plurality of stations or modules through which part-carrying platens move along a path comprising successive horizontal path portions extending at right angles to one another. The platens are driven along successive path portions by successive belts which at least partially support the platens, the improvement being that each module has as many belts (93, 99, 118) as it has perpendicular path portions, with each belt comprising an endless loop having a driving portion (95) and a return portion (94). The portions extend between a pair of vertical axis pulleys (88, 94') located in the vicinity of the ends of each path portion, with successive perpendicular endless loops being at different horizontal levels, whereby successive loops within a module share a common pulley having two loop-receiving grooves (94, 102) at the different levels, thereby enabling a single motor to drive all the endless loops within any one module.

An installation according to claim 4, wherein said groove in the top of a guide rail rises at the end of a straight path portion to so lift the platen that a strip portion for drive in the following perpendicular direction is lifted above the belt for drive in said direction, said rising portion ending in a transverse groove enabling the platen to drop onto said drive belt under the effect of its own weight.
Claim 7
Dependent Claim
48 words
An installation according to claim 4, wherein a guide rail having a groove in its top surface also includes an upwardly projecting flange at the intersection of two perpendicular path portions to help keep the platen in place by means of the guide block co-operating with the flange.
Claim 8
Dependent Claim
39 words
An installation according to claim 1, wherein drive zones are provided on two different levels on the undersides of the platens, the drive zones on one level being at right angles to the drive zones of the other level.
Claim 9
Dependent Claim
73 words
An installation according to claim 7, wherein the platens gave first strip zones running along parallel margins of the underside of the platens, guide blocks running perpendicularly to said first strip zones and having strip zones for drive at right angles to said first strip zones, and studs located at the ends of said guide blocks, said studs having ball bearings projecting down therefrom providing means for positioning the platen during handling thereof.
Claim 10
Dependent Claim
25 words

Claim 11
Dependent Claim
51 words
An installation according to claim 1, wherein crossing points are provided where a platen may take one or the other of two perpendicular exit directions, with the endless loop belts for each of the exit directions leaving a gap for an endless loop to drive the platens into the crossing point.
Claim 12
Dependent Claim
37 words
An installation according to claim 10, wherein the endless loop belts for longitudinal drive are at a higher level than the belts for transverse drive, and wherein said gap between the belts extends in the transverse direction.
