We claim:
1. A transport device for transporting containers each having at least two webs that run in parallel, the transport device comprising:
at least two parallel rows of a series of running rollers on which the webs of the containers can run;
at least one group of drive rollers transmitting a drive force to the webs of the containers, said drive rollers including a primary drive roller and at least one secondary drive roller, each of said drive rollers integrated in one of said rows of said series of said running rollers;
a motor driving said primary drive roller, and said drive rollers are coupled with one another in such a way that said primary drive roller drives said secondary drive roller; and
lateral bearers disposed in parallel and at a distance from one another, said running rollers and said drive rollers are attached to said lateral bearers.
2. The transport device according to claim 1, including a force transmission shaft coupling said drive rollers to one another.
3. The transport device according to claim 1, wherein said running rollers rotate freely in said lateral bearers.
4. The transport device according to claim 1, wherein said drive rollers are mounted in said lateral bearers so as to stand opposite one another.
5. The transport device according to claim 1, wherein in relation to the webs of the containers that can be transported on said running rollers, said running rollers form, at their circumference facing the containers, an imagined line, and in that said drive rollers extend past the imagined line in order to enable a transmission of the drive force to the webs.
6. The transport device according to claim 1, including drive wheels for a transmission of the drive force to the webs are disposed around said drive rollers.
7. The transport device according to claim 6, including rubber coatings, for assisting in the transmission of the drive force to the webs, are disposed on a circumference of said drive wheels.
8. The transport device according to claim 2, including two transmission wheels disposed on said force transmission shaft, a first of said transmission wheels stands in contact with said primary drive roller and transmits a rotation thereof to said force transmission shaft, and a second of said transmission wheels transmits the rotation of said force transmission shaft to said secondary drive roller.
9. The transport device according to claim 8, wherein said transmission wheels and said drive rollers each have rubber coatings disposed on a circumference thereof and a transmission of force between said drive rollers and said transmission wheels takes place through friction of said rubber coatings.
10. The transport device according to claim 8, including drive wheels disposed on a circumference of said drive rollers, said drive wheels and said drive rollers are each coated on a circumference with rubber coatings, and a transmission of force between said drive rollers and said transmission wheels takes place through friction of said rubber coatings of said drive wheels and of said transmission wheels.
11. The transport device according to claim 1, wherein said secondary drive roller is one of a plurality of secondary drive rollers each disposed spaced apart within one of said rows of said series of said running rollers.
12. The transport device according to claim 1, wherein said at least one group of drive rollers is one of a plurality of groups of drive rollers and said motor drives said plurality of groups of drive rollers.
13. The transport device according to claim 1, wherein said at least one group of drive rollers is one of a plurality of groups integrated into said rows of said series of said running rollers, said plurality of groups of drive rollers are spaced from one another in such a way that at all times at least one of said plurality of groups of drive rollers can drive the webs of the containers.
14. A method for transporting semiconductor wafers, which comprises the steps of:
providing a transport device for transporting containers each having at least two webs that run in parallel, the transport device includes:
at least two parallel rows of a series of running rollers on which the webs of the containers can run;
at least one group of drive rollers transmitting a drive force to the webs of the containers, the drive rollers including a primary drive roller and at least one secondary drive roller, each of the drive rollers integrated in one of the rows of the series of the running rollers;
a motor driving the primary drive roller, and the drive rollers are coupled with another in such a way that the primary drive roller drives the secondary drive roller; and
lateral bearers disposed in parallel and at a distance from one another, the running rollers and the drive rollers are attached to the lateral bearers; and
transporting the semiconductor wafers in the drive containers.
The claims below are in addition to those above.
