Abstract

The invention pertains to a device for loading goods into and/or unloading goods from a loading space 25, particularly a container, with a conveyor arm 1 that features a transfer station 5, 7, 9 for receiving the goods in the region of its proximal end and a transfer station 21, 23 for delivering the goods in the region of its distal end, wherein the conveyor arm 1 features a transport section 13, 15, 17, 19, 21 for transporting the goods from the transfer station 5, 7, 9 to the transfer station 20, wherein the transfer station 20 is realized in the form of a transfer and/or removal head 21, 23 that automatically deposits the goods at a predefined position in the loading space (25) and/or automatically picks up the goods from a predefined position in the loading space (25), and wherein the conveyor arm 1 is able to continuously transport the stream of successive goods to and/or from the predefined position.

Claims

1. A conveyor arm for transferring goods along a path to or from a predefined position within a loading space, the conveyor arm including:

(a) a proximal end transfer station at a proximal end of the conveyor arm, the proximal end transfer station for moving goods along a proximal end portion of the path;

(b) a transfer head at a distal end of the conveyor arm, the transfer head comprising a distal end rotary conveyor which is rotatable about a vertical axis located at the center of the distal end rotary conveyor, the transfer head for automatically depositing the goods at the predefined position within the loading space or automatically picking up the goods from the predefined position in the loading space and for moving the goods along a distal end portion of the path;

(c) a transport section located between the proximal end transfer station and the transfer head, the transport section for transporting the goods along an intermediate portion of the path between the proximal end port of the path and the distal end portion of the path; and

(d) wherein the proximal end transfer station, the transfer head, and the transport section are operable to continuously transport a stream of the goods to or from the predefined position within the loading space.

2. The conveyor arm of claim 1 wherein the transfer head is moveable vertically with respect to the transport section.

3. The conveyor arm of claim 1 wherein the proximal end transfer station includes a proximal end rotary conveyor which is arranged to allow a lateral pivoting motion of the transport section about a central axis of rotation of the proximal end rotary conveyor.

4. The conveyor arm of claim 3 wherein at least one of the distal end rotary conveyor and the proximal end rotary conveyor is configured to assume a controllable angular position during the reception of the goods in order to allow an alignment of an individual object relative to a desired end position for the good in the loading space.

5. The conveyor arm of claim 4 wherein at least one of the distal end rotary conveyor and the proximal end rotary conveyor comprises an altogether rotatable device with a plurality of individual belts that can be separately controlled independently of one another so as to affect the alignment of an object situated thereon.

6. The conveyor arm of claim 1 wherein the distal end rotary conveyor comprises an altogether rotatable device with a plurality of individual belts that can be separately controlled independently of one another so as to affect the alignment of an object situated thereon.

7. The conveyor arm of claim 1 wherein the distal end rotary conveyor is configured to assume a controllable angular position during the reception of the goods in order to allow an alignment of an individual object relative to a desired end position for the good in the loading space.

8. The conveyor arm of claim 1 further including at least one collision avoidance or position determining sensor arranged on the transfer head.

9. The conveyor arm of claim 1 wherein at least one of orientation in space and speed and final position of an object to be deposited in the loading space can be calculated by means of a sensor positioned on the transfer head and an evaluation device.

10. The conveyor arm of claim 1 wherein the transport section includes a telescopic conveyor operable to vary the overall length of the transport section.

11. The conveyor arm of claim 1 wherein the transport section and transfer head are positionable in an idle position at half the height of the loading space.

12. The conveyor arm of claim 1 wherein the transfer head includes a frame that protrudes over the end of a conveyor belt included on the transfer head.
