Abstract

In order to be able to plan and control the movement of a transportation unit of a conveying device along a conveying line more easily and more quickly, provision is made so that at least part of the conveying line (2) is assigned at least one logical sector (LSi), wherein the at least one logical sector (LSi) is allocated to one or more conveying segments (FSi) or parts thereof, a movement profile for the transportation unit (TEi) is allocated to the at least one logical sector (LSi), the transportation unit (TEi) is moved in accordance with the specified movement profiles along the at least one logical sector (LSi) and in doing so a new setpoint (S) of the movement is ascertained in each cycle step of the setpoint selection, and the setpoint (S) is transferred via the allocation to one or more conveying segments (FSi), or parts thereof, to the allocated conveying segment(s) (FSi) for adjustment.

First claim

The invention claimed is:

1. A method for controlling the movement of a transportation unit of a conveying device, which is formed as a long-stator linear motor, the method comprising:
moving the transportation unit along a conveying line, which comprises a number of conveying segments;
assigning at least part of the conveying line, along which the transportation unit is moved, at least one logical sector;
allocating the at least one logical sector to one or more conveying segments or parts thereof;
allocating a movement profile for the transportation unit to the at least one logical sector;
moving the transportation unit in accordance with the specified movement profile along the at least one logical sector to ascertain a setpoint of the movement in a setpoint selection cycle step; and
transferring the setpoint to the one or more conveying segments, or parts thereof,
wherein the movement of the transportation unit, which is controlled on the basis of the logical sectors, is independent of underlying hardware of the conveying device.

2. A method for controlling the movement of a transportation unit of a conveying device, which is formed as a long-stator linear motor, the method comprising:
moving the transportation unit along a conveying line, which comprises a number of conveying segments;
assigning at least part of the conveying line, along which the transportation unit is moved, at least one logical sector;
allocating the at least one logical sector to one or more conveying segments or parts thereof;
allocating a movement profile for the transportation unit to the at least one logical sector;
moving the transportation unit in accordance with the specified movement profile along the at least one logical sector to ascertain a setpoint of the movement in a setpoint selection cycle step; and
transferring the setpoint via the allocation to the one or more conveying segments, or parts thereof,
wherein the logical sector comprises a starting point, an end point, and a length.

3. The method according to claim 2 , wherein any position between the starting point and the end point of the logical sector corresponds to a unique position on an allocated conveying segment or a number of allocated conveying segments.

4. The method according to claim 1 , further comprising allocating to the logical sector a movement profile, which is run through by each transportation unit on the logical sector.

5. The method according to claim 1 , further comprising allocating to the logical sector different movement profiles for different transportation units.

6. The method according to claim 1 , wherein the allocation between the logical sector and a conveying segment also contains information regarding a necessary switch position of a switch.

7. The method according to claim 2 , further comprising allocating to the logical sector a movement profile, which is run through by each transportation unit on the logical sector.

8. The method according to claim 2 , further comprising allocating to the logical sector different movement profiles for different transportation units.

9. The method according to claim 2 , wherein the allocation between the logical sector and a conveying segment also contains information regarding a necessary switch position of a switch.

10. The method according to claim 2 , wherein the moving of the transportation unit in accordance with the specified movement profile along the at least one logical sector ascertains a new setpoint of the movement in each cycle step of the setpoint selection.

11. The method according to claim 2 , wherein the movement of the transportation unit is achieved without knowledge of underlying hardware of the conveying device.

12. The method according to claim 11 , wherein the underlying hardware of the conveying device comprises the conveying segments.

13. The method according to claim 1 , wherein the moving of the transportation unit in accordance with the specified movement profile along the at least one logical sector ascertains a new setpoint of the movement in each cycle step of the setpoint selection.

14. The method according to claim 1 , wherein the movement of the transportation unit is achieved without knowledge of the underlying hardware of the conveying device.

15. The method according to claim 14 , wherein the underlying hardware of the conveying device comprises the conveying segments.
