Abstract

Method for adjusting a transport vehicle for a container handling system, where the transport vehicle comprises two oppositely disposed secondary parts which can be driven electromagnetically as an armature by way of a linear motor system of the container handling system, wherein in a device for adjusting, a first magnetic force of the first secondary part is determined with a sensor, in that a second magnetic force of the second secondary part is determined with the sensor; and in that the first magnetic force and the second magnetic force are compared with one another and/or with at least one reference force, and the two secondary parts are adjusted based thereon at the transport vehicle in such a way that the first magnetic force and the second magnetic force are of the same magnitude.

First claim

The invention claimed is:

1. A method for adjusting a transport vehicle for a container handling system, where said transport vehicle comprises two oppositely disposed secondary parts which are electromagnetically drivable as an armature by way of a linear motor system of said container handling system, the method comprising:
determining a first magnetic force of a first secondary part of said two oppositely disposed secondary parts with a sensor,
determining a second magnetic force of a second secondary part of said two oppositely disposed secondary parts with said sensor, and
comparing the first magnetic force and the second magnetic force with one another and/or with at least one reference force and said two oppositely disposed secondary parts are adjusted based thereon at said transport vehicle such that the first magnetic force and the second magnetic force are of a same magnitude.

2. The method according to claim 1 , where said transport vehicle is turned around after the first magnetic force has been determined and the second magnetic force is then determined.

3. The method according to claim 1 , where a respective magnetic field of said first and said second secondary part acts upon said sensor over a distance when the first and the second magnetic forces are determined.

4. The method according to claim 1 , where a position of said first and/or said second secondary part on said transport vehicle is changed by removing or adding at least one spacer element when said transport vehicle is adjusted.

5. The method according to claim 1 , where said transport vehicle is placed in a stationary manner against a measuring table of said device for adjusting when the first and the second magnetic force is determined.

6. The method according to claim 5 , where said transport vehicle is placed against said measuring table such that said first secondary part faces said sensor when the first magnetic force is determined, and said transport vehicle is then turned around and placed against said measuring table such that said second secondary part faces said sensor.

7. The method according to claim 5 , where said transport vehicle is placed against said measuring table such that said first secondary part is oriented towards a contact surface of said measuring table for said transport vehicle when the first magnetic force is determined, and said transport vehicle is then turned around and placed against said measuring table such that said second secondary part is oriented towards said contact surface of said measuring table for said transport vehicle.

8. A device for adjusting a transport vehicle for a container handling system, where said transport vehicle comprises at least one secondary part, which is movable electromagnetically as an armature by way of a linear motor system of said container handling system, wherein
said device comprises a sensor and a measuring table for stationary placement of said transport vehicle relative to said sensor, and
said sensor is configured to determine magnetic forces in order to determine a magnetic force of a first secondary part of said at least one secondary part.

9. The device according to claim 8 , where said sensor comprises a Hall element for determining the magnetic forces by way of Hall effect.

10. The device according to claim 8 , where said measuring table for the stationary placement of said transport vehicle comprises at least one contact surface which interacts with rollers and/or contact elements of said transport vehicle when the magnetic forces are determined.

11. The device according to claim 10 , where a force sensor is arranged separately from a magnetic element of said sensor and a force introduction point of said force sensor is firmly connected to said at least one contact surface.

12. The device according to claim 8 , where said sensor comprises a magnetic element for interaction with said at least one secondary part and a force sensor.

13. The device according to claim 12 , where said magnetic element is firmly connected to a force introduction side of said force sensor.

14. The device according to claim 8 , wherein said at least one secondary part comprises two oppositely disposed secondary parts.

15. The device according to claim 14 , wherein said sensor is configured to determine the magnetic forces in order to determine a magnetic force of a second secondary part of said two oppositely disposed secondary parts.
