Abstract
A returning system for rail-borne transporting carts without self-driving means is provided with an auxiliary drive system which has an auxiliary drive wheel in the form of a friction wheel. The friction wheel clamps, for transporting a cart and cooperating with a contact pressure part with suitable parts of the transporting cart and transfers the latter from a transporting track to a return track located under the transporting track.
Claims26
A returning system (1, 1', 1") for transporting carts (3, 3', 3") born on running rails without self-driving means, the transporting carts being moved by a first common main drive system (I, I", III") on a transporting track (2, 2', 2") an auxiliary drive system (4, 4', 4") for transferring the transporting carts (3, 3', 3") to an inverted position by moving the carts over a vertical curve (5, 5', 5") onto an end of a return track (6, 6', 6") located parallel to and under the transporting track, the return track being provided with a second common main drive system (II, II', III");
- the auxiliary drive system (4, 4', 4") having an auxiliary drive wheel (8, 8', 8") with a friction surface in juxtaposition with the vertical curve (5, 5', 5") which is driven to be rotatable about a horizontal axis and a contact pressure part (10, 10', 10") arranged concentrically with the auxiliary drive wheel (8, 8', 8"), which contact pressure part (10, 10', 10" ) engages each of the transporting carts in turn and urges the transporting carts (3, 3', 3") into frictional engagement with the auxiliary drive wheel (8, 8', 8") resulting in a non-positive transfer of the transporting cart over the vertical curve (5, 4', 4").
A system for returning transport carriages, the system comprising:
- external driving means for driving the carriages only to transverse a first horizontal path in one direction and a second horizontal path, beneath the first path, in the opposite direction;
- direction-reversing, vertically oriented, drivers at the beginning and end of each path, the vertically oriented drivers being independent from the external driving means:
- driver-engaging means on each carriage for engaging the reversing drivers at the beginning and end of each path;
- means for urging the driver-engaging means into engagement with the reversing drivers;
- and
- a wheel comprising each reversing driver, the wheels each having a circular peripheral surface for frictional engagement with the driver-engaging means when the means for urging the driver-engaging means urges the driver-engaging means into contact with the reversing drivers.
