Abstract

A conveying apparatus for goods comprises at least one goods source which provides the goods by means of conveyor containers, a plurality of goods sinks to which the goods are conveyed, and an endless conveyor which connects the at least one goods source and the goods sinks in terms of conveying technology and has a first conveyor strand and a second conveyor strand which follows the first conveyor strand along a goods conveying direction in the endless conveyor, wherein only the first conveyor strand has a fixed conveyor container entrainment.

Claims (36)

1 . A conveying apparatus for goods comprising:

at least one source of goods configured to provide goods via conveyor containers;

a plurality of sinks; and

an endless conveyor coupling the at least one source of goods and the plurality of sinks, the endless conveyor including a first conveyor strand and a second conveyor strand following the first conveyor strand along a goods conveying direction, wherein only the first conveyor strand has a fixed conveyor container entrainment, and wherein the second conveyor strand is built without a fixed conveyor container entrainment such that the conveyor containers and the conveyor container entrainment are decoupled along the second conveyor strand.

2 . The conveying apparatus according to claim 1 , wherein the sinks of the plurality of sinks are designed as goods dispatching points.

3 . The conveying apparatus according to claim 1 , wherein the sinks of the plurality of sinks are designed as packing places.

4 . The conveying apparatus according to claim 1 , wherein the first conveyor strand has a first conveyor length and the second conveyor strand has a second conveyor length shorter than the first conveyor length.

5 . The conveying apparatus according to claim 1 , wherein the second conveyor strand is in the form of a gravity conveyor.

6 . The conveying apparatus according to claim 1 , wherein the second conveyor strand is in the form of an inclined conveyor rail.

7 . The conveying apparatus according to claim 1 , wherein the first conveyor strand is in the form of an overhead conveyor for suspended conveyance of the conveyor containers.

8 . The conveying apparatus according to claim 1 , wherein the first conveyor strand is connected to the at least one source of goods and the plurality of sinks.

9 . The conveying apparatus according to claim 8 , wherein the first conveyor strand is connected directly to the at least one source of goods and the plurality of sinks.

10 . The conveying apparatus according to claim 1 , wherein the first conveyor strand has a conveyor drive for fixed conveyor container entrainment.

11 . The conveying apparatus according to claim 10 , wherein the conveyor drive is in the form of a drive chain operable in a conveyor rail and cooperating holding members, each of which is couplable to a conveyor container.

12 . The conveying apparatus according to claim 1 , wherein the at least one source of goods is one of a warehouse, a sorting unit, or a circulating storage unit.

13 . The conveying apparatus according to claim 12 , wherein the sorting unit is a matrix sorter.

14 . The conveying apparatus according to claim 1 , wherein each sink of the plurality of sinks has an unloading unit for unloading goods from the conveyor containers and a discharge unit for discharging conveyor containers from the endless conveyor.

15 . The conveying apparatus according to claim 14 , wherein the unloading unit is an automatic unloading unit.

16 . The conveying apparatus according to claim 1 , further including a discharge line coupled to the endless conveyor for discharging unloaded conveyor containers from the endless conveyor.

17 . The conveying apparatus according to claim 16 , wherein the discharge line is coupled to the first conveyor strand.

18 . The conveying apparatus according to claim 16 , wherein the discharge line is coupled to the first conveyor strand along the goods conveying direction between the sinks of the plurality of sinks and the second conveyor strand.

19 . The conveying apparatus according to claim 1 , wherein the endless conveyor is in the form of an overhead conveyor for the suspended conveyance of the conveyor containers.

20 . The conveying apparatus according to claim 19 , wherein the overhead conveyor is operable vertically above the plurality of sinks.

21 . The conveying apparatus according to claim 19 , wherein the conveyor containers are each in the form of conveyor bags.

22 . The conveying apparatus according to claim 21 , wherein the conveyor bags are each configured to be unloaded individually and/or in an automated manner.

23 . A conveying method for goods, the method comprising:

providing goods via conveyor containers at at least one source of goods; and

conveying goods along a goods conveying direction to one sink of a plurality of sinks via a closed endless conveyor having a first conveyor strand and a second conveyor strand following the first conveyor strand in a goods conveying direction, wherein goods are conveyed only along the first conveyor strand with fixed conveyor container entrainment, and wherein the goods are accumulated in the second conveyor strand.

24 . The conveying method according to claim 23 , further comprising returning goods from the second conveyor strand into the first conveyor strand.

25 . The conveying method according to claim 24 , wherein returning goods is prioritized over an insertion of goods from the source of goods.

26 . The conveying method according to claim 23 , further comprising unloading at least one good from the conveyor containers at the sinks of the plurality of sinks and discharging the conveyor containers from the endless conveyor.

27 . The conveying method according to claim 26 , wherein the unloading is an automated unloading.

28 . A conveying apparatus for goods comprising:

at least one source of goods configured to provide goods via conveyor containers;

a plurality of sinks; and

an endless conveyor coupling the at least one source of goods and the plurality of sinks, the endless conveyor including a first conveyor strand and a second conveyor strand following the first conveyor strand along a goods conveying direction, wherein only the first conveyor strand has a fixed conveyor container entrainment, and wherein the second conveyor strand is in the form of an accumulation conveyor.
