Abstract

A transporting device transports objects in a transport direction from a loading region to an unloading region. The device includes a first conveying unit and a second conveying unit which are arranged one behind the other in the transport direction. Efficient unloading of the objects from the transporting device is achieved by providing a separating device between the first and second conveying units. The separating device is configured to separate the objects into at least two object groups dependent on at least one object property.

First claim

The invention claimed is:

1. A transporting device for transporting objects in a transport direction from a loading region to an unloading region, the transporting device comprising:
a first conveying unit and a second conveying unit disposed one behind another in the transport direction; and
a separating device disposed between said first conveying unit and said second conveying unit, said separating device being configured for separating the objects into at least two object groups in dependence on at least one object property;
said separating including an input switch disposed in the transport direction behind said first conveying unit and an output switch disposed in the transport direction before said second conveying unit and configured to assume a first position and a second position, and wherein, in the first position of said output switch, the objects of the first object group are conveyed to the second conveying unit and, in the second position of the output switch, the objects of the second object group are conveyed to the second conveying unit.

2. The transporting device according to claim 1 , wherein said separating device includes an input switch disposed in the transport direction behind said first conveying unit and configured to assume a first position and a second position, and wherein, in operation, the objects are separated into the first object group in the first position of said input switch and into the second object group in the second position of said input switch.

3. The transporting device according to claim 1 , which comprises at least two storage regions each assigned to a respective object group, and into which the objects are to be separated.

4. The transporting device according to claim 3 , wherein said storage regions are disposed vertically above one another.

5. The transporting device according to claim 1 , which comprises at least two storage regions each assigned to a respective object group, and into which the objects are to be separated, and wherein the input switch and/or the output switch and/or the first and second storage regions are mutually separate conveying units configured for transporting the objects in the transport direction.

6. The transporting device according to claim 3 , wherein one or both of said first and second storage areas include a plurality of conveying units disposed one behind another.

7. The transporting device according to claim 1 , which further comprises a control device configured for controlling said conveying units and said separating device.

8. The transporting device according to claim 7 , wherein said control device includes a measuring device configured for detecting the at least one object property, and wherein said control device controls said separating device as a function of the at least one object property.

9. The transporting device according to claim 7 , wherein said control device includes a counting device for counting a number of objects of the first and second object groups, and wherein said control device controls the separating device as a function of the counts.

10. The transporting device according to claim 1 , wherein said second conveying unit is configured to assume a first position and a second position, and wherein each said position is assigned to a respective one of the object groups.

11. A method for transporting objects along a transport direction from a loading region into an unloading region, the method comprising:
providing a first conveying unit, a second conveying unit, and a separating device with an input switch disposed in a transport direction behind said first conveying unit and output switch disposed in the transport direction before the second conveying unit;
while conveying the objects from the loading region to the unloading region, separating the objects with the separating device, in dependence on at least one object property, into at least two object groups including a first object group and a second object group; and
subsequently, first conveying the objects of the first object group and then conveying the objects of the second object group to the unloading region, by causing the output switch to selectively assume a first position wherein the objects of the first object group are conveyed to the second conveying unit and a second position wherein the objects of the second object group are conveyed to the second conveying unit.
