Abstract
Abstract The invention relates to a loading and unloading station for commercial vehicles and containers consisting of a travelling unit, a roller conveyor or chain conveyor, and a transport conveyor, wherein, in accordance with the invention, the transport conveyor and the roller conveyor or chain conveyor are swivel-mounted on the travelling unit and are designed to slide in transverse direction and can be adjusted in transverse and vertical direction. In this case, the travelling unit can be mounted on a stationary or a supporting structure to move in the direction of transport and transversely thereto. The travelling unit may also be equipped with a lifting mechanism to adjust the height of the chain and transport conveyor. Furthermore, the transport conveyor may be provided with support rollers that run transversely to the direction of transport. Finally, a height equalizer may be mounted on the supporting structure.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
51 words
A loading and unloading station for commercial vehicles and containers comprising: a supporting structure, a travelling unit independently movable longitudinally and radially on the support structure, a first drivable conveyor, and a second drivable transport conveyor both being swivel-mounted on the travelling unit and being adjustable in transverse and vertical directions.
Claim 2
Dependent Claim
51 words
A loading and unloading station for commercial vehicles and containers comprising: a supporting structure, a travelling unit independently movable longitudinally and radially on the support structure, a first drivable conveyor, and a second drivable transport conveyor both being swivel-mounted on the travelling unit and being adjustable in transverse and vertical directions.
Claim 3
Dependent Claim
40 words
The loading and unloading station for commercial vehicles and containers as recited in claim 1, wherein the travelling unit includes rollers which engage the supporting structure for moving the travelling unit in the direction of transport "X" and transversely thereto.
Claim 4
Dependent Claim
34 words
The loading and unloading station for commercial vehicles and containers as recited in claim 1, wherein the travelling unit further includes a lifting mechanism for adjusting the height of the first and second conveyors.
Claim 5
Dependent Claim
42 words
The loading and unloading station for commercial vehicles and containers as recited in claim 1, further comprising support rollers connected to the second transport conveyor and running transversely to the direction of transport "X", for supporting the second conveyor in a container.
Claim 6
Dependent Claim
33 words
The loading and unloading station for commercial vehicles and containers as recited in claim 1, further comprising a height equalizer mounted on the supporting structure for adjusting the height of the second conveyor.
Claim 7
Dependent Claim
34 words
The loading and unloading station for commercial vehicles and containers as recited in claim 2 wherein the travelling unit further includes a lifting mechanism for adjusting the height of the first and second conveyors.
Claim 8
Dependent Claim
42 words
The loading and unloading station for commercial vehicles and containers as recited in claim 2 further comprising support rollers connected to the second transport conveyor and running transversely to the direction of transport "X", for supporting the second conveyor in a container.
Claim 9
Dependent Claim
42 words
The loading and unloading station for commercial vehicles and containers as recited in claim 3 further comprising support rollers connected to the second transport conveyor and running transversely to the direction of transport "X", for supporting the second conveyor in a container.
Claim 10
Dependent Claim
33 words
The loading and unloading station for commercial vehicles and containers as recited in claim 2 further comprising a height equalizer mounted on the supporting structure for adjusting the height of the second conveyor.
Claim 11
Dependent Claim
33 words
The loading and unloading station for commercial vehicles and containers as recited in claim 3 further comprising a height equalizer mounted on the supporting structure for adjusting the height of the second conveyor.
Claim 12
Dependent Claim
33 words
The loading and unloading station for commercial vehicles and containers as recited in claim 4 further comprising a height equalizer mounted on the supporting structure for adjusting the height of the second conveyor.
Claim 13
Dependent Claim
153 words
A loading and unloading station for moving pallets into and out of a container having a floor and a rear, comprising: a supporting structure having a distal end movable into a fixed position adjacent the rear of the container; a travelling unit movably mounted on the supporting structure for movement in a longitudinal direction towards and away from the vehicle, and transversely to the longitudinal direction; a first conveyor and a second, transport conveyor mounted on the travelling unit, for moving pallets into the container, the second conveyor having a proximal end connected to the travelling unit and a distal end supported on and slidable over the distal end of the support structure, and being slidable into the container by longitudinal movement of the travelling unit, the travelling unit being slidable away from the container by the conveying action of the second conveyor when a pallet reaches its inner-most position in the container.
Claim 14
Dependent Claim
153 words
A loading and unloading station for moving pallets into and out of a container having a floor and a rear, comprising: a supporting structure having a distal end movable into a fixed position adjacent the rear of the container; a travelling unit movably mounted on the supporting structure for movement in a longitudinal direction towards and away from the vehicle, and transversely to the longitudinal direction; a first conveyor and a second, transport conveyor mounted on the travelling unit, for moving pallets into the container, the second conveyor having a proximal end connected to the travelling unit and a distal end supported on and slidable over the distal end of the support structure, and being slidable into the container by longitudinal movement of the travelling unit, the travelling unit being slidable away from the container by the conveying action of the second conveyor when a pallet reaches its inner-most position in the container.
Claim 15
Dependent Claim
45 words
A loading and unloading station as recited in claim 12, wherein the travelling unit further includes a lifting mechanism for adjusting the height of the first conveyor and the proximal end of the second conveyor to be substantially aligned with the floor of the container.
Claim 16
Dependent Claim
33 words
A loading and unloading station as recited in claim 12, further comprising support rollers connected to the second conveyor for supporting the second conveyor on the floor of the container when disposed therein.
Claim 17
Dependent Claim
46 words
A loading and unloading station as recited in claim 12, further comprising a height equalizer mounted on the distal end of the supporting structure for adjusting the height of the distal end of the second conveyor to be substantially aligned with the floor of the container.
Claim 18
Dependent Claim
40 words
A loading and unloading station as recited in claim 12, wherein the second conveyor is pivotal about a first, vertical axis and a second, horizontal axis, the horizontal axis being transverse the longitudinal direction of movement of the travelling unit.
Claim 19
Dependent Claim
32 words
A loading and unloading station as recited in claim 12, wherein the second conveyor has a distal end portion which is sloped to facilitate separation of a pallet from the second conveyor.
