Method for operating a conveyor for successive goods, and corresponding conveyor system
A method for operating an overhead conveyor for successive goods is disclosed, in which the goods are loaded onto the overhead conveyor one by one by means of an inward transfer means and are transferred outward at a predefined point of the overhead conveyor by means of a switch, the distance between successive goods on the overhead conveyor either being minimised if said successive goods are to be transferred outward at the same switch, or the distance between the successive goods on the overhead conveyor being increased in such a way that said distance corresponds to the minimum outward transfer distance if the successive goods are not to be transferred outward at the same switch.
1. A method for operating a conveyor, wherein the conveyor is an overhead conveyor having a chain and a chain drive, the chain defining fixed divisions and the distance between the goods is fixed by the goods cooperation with the chain, the method comprising the steps of:
feeding the goods onto the conveyor one after another;
discharging the goods at a predetermined location of the conveyor via a switch point; and
minimizing a distance between successive goods on the conveyor when successive goods are to be discharged at the same switch point or enlarging the distance between the successive goods on the conveyor such that it corresponds to a minimum discharge distance when the successive goods are not to be discharged at the same switch point,
wherein the goods having the same destination are introduced within a small distance of each other as a batch, whereas goods having a different destination are spaced apart from each other such that they can be discharged in a targeted manner and then together as a batch.
2. The method for operating a conveyor as claimed in claim 1 , wherein said minimizing the distance between the successive goods on the conveyor when the successive goods are to be discharged at the same switch point is further based on the successive goods belonging to a shared order and/or destination.
3. The method for operating a conveyor as claimed claim 1 , further comprising adjusting the distance between the successive goods on the conveyor for further optimisation using a thickness measuring device.
4. The method for operating a conveyor as claimed in claim 1 , further comprising providing a conveyor with gathering path having a plurality of introduction means and a plurality of switch points.
5. The method for operating a conveyor as claimed in claim 1 , further comprising identifying the goods and/or the properties thereof when the goods are feed to the conveyor are determined.
6. The method for operating a conveyor as claimed in claim 1 , further comprising determining thickness of the goods in the conveying direction, when the goods are feed to the conveyor.
7. A method for operating a conveyor, wherein the conveyor is an overhead conveyor having a chain and a chain drive, the chain drive defining fixed divisions and the distance between the goods is fixed by the goods cooperation with the chain, the method comprising the steps of:
feeding the goods onto the conveyor one after another;
discharging the goods at a predetermined location of the conveyor via a switch point;
minimizing a distance between successive goods on the conveyor when the successive goods are to be discharged at the same switch point or enlarging the distance between the successive goods on the conveyor such that it corresponds to a minimum discharge distance when the successive goods are not to be discharged at the same switch point,
wherein the goods having the same destination are introduced within a small distance of each other as a batch, whereas goods having a different destination are spaced apart from each other such that they can be discharged in a targeted manner and then together as a batch; and
determining the minimum discharge distance based on the distance between the successive switch points in the conveying direction.
8. A method for operating a conveyor, wherein the conveyor is an overhead conveyor having a chain and a chain drive, the chain drive defining fixed divisions and the distance between the goods is fixed by the goods cooperation with the chain, the method comprising the steps of:
feeding the goods onto the conveyor one after another;
discharging the goods at a predetermined location of the conveyor via a switch point;
minimizing a distance between successive goods on the conveyor when the successive goods are to be discharged at the same switch point or enlarging the distance between the successive goods on the conveyor such that it corresponds to a minimum discharge distance when the successive goods are not to be discharged at the same switch point,
wherein the goods having the same destination are introduced within a small distance of each other as a batch, whereas goods having a different destination are spaced apart from each other such that they can be discharged in a targeted manner and then together as a batch; and
wherein said feeding includes fixing the distance between the successive goods upon introduction of the goods onto the conveyor.
9. A conveying system comprising:
an overhead chain conveyor for goods following one behind the other;
at least one feed unit to feed the goods onto the overhead chain conveyor one after another;
the overhead chain conveyor having at least one switch point in order to discharge goods at a predetermined location of the overhead chain conveyor via the switch point;
a controller which is configured to minimise the distance between successive goods on the overhead chain conveyor when said goods are to be discharged at the same switch point, or to enlarge the distance between the successive goods on the overhead chain conveyor such that it corresponds to a minimum discharge distance when said goods are not to be discharged at the same switch point.
10. The conveyor system as claimed in claim 9 , wherein the overhead conveyor includes a chain and a chain drive, the chain defining fixed divisions, and the distance between the goods is fixed by the goods cooperation with the chain.
11. The conveyor system as claimed in claim 9 , wherein the controller is configured to introduce goods having the same destination within a small distance of each other as a batch, whereas goods having a different destination are spaced apart from each other such that they can be discharged in a targeted manner and then together as a batch.
