Abstract

For a flexibly configurable and easily expandable transport route of a long stator linear motor with transport route modules, it is provided that, in a two-sided route section with a transport route module on both sides, an intermediate space is provided between two transport route modules in transverse direction, and the transport unit is arranged at least partially in this intermediate space. In this way, a movement path is formed midway of this intermediate space in transverse direction that the transport unit follows during movement in longitudinal direction by the guidance on the transport route modules, and the movement path is arranged by the arrangement of the transport route module in transverse direction at a distance of (r·a) from the starting point and ending point, where r is an odd, whole number.

First claim

What is claimed:

1. A transport route of a long stator linear motor along which a transport unit of the long stator linear motor is movable in a longitudinal direction, comprising:
at least two transport route modules that are arranged adjacent to each other in longitudinal direction, wherein each of the at least two transport route modules forms a guiding side on a side of the transport route module lying in a transverse direction oriented transverse to the longitudinal direction and the transport unit is mounted in a guided manner on the guiding side and is arranged to be movable in the longitudinal direction on the guiding side, and
at least one of a single-sided route section having transport route modules on only one side or a two-sided route section having transport route modules on both sides, wherein, in the two-sided route section, the guiding sides of transport route modules are arranged on the two sides facing each other,
wherein the at least two transport route modules each have on a respective guiding side a starting point and an ending point, which are situated on grid corner points of an (a×a) grid having a predetermined grid length a and grid coordinates (p, q), wherein p, q are whole numbers,
wherein, in the two-sided route section, in a transverse direction between the at least two transport route modules, an intermediate space is provided and the transport unit is arranged at least partially in the intermediate space, whereby midway of the intermediate space in the transverse direction, a movement path is formed which the transport unit follows when moving in the longitudinal direction by the guidance on the transport route modules and the movement path is arranged by the arrangement of the transport route modules in the transverse direction at a distance of (r·a) from the starting point and ending point, wherein r is an odd, whole number,
wherein at least one transport route module is designed as a straight transport route module with a length (L·a) having a predetermined whole, positive number L≠0.

2. Transport route according to claim 1 , wherein, on the transport route modules, a plurality of drive coils are arranged adjacent to each other in longitudinal direction, and an installation width of a drive coil in the longitudinal direction corresponds to the grid length a.

3. A transport route of a long stator linear motor along which a transport unit of the long stator linear motor is movable in a longitudinal direction, comprising:
at least two transport route modules that are arranged adjacent to each other in longitudinal direction, wherein each of the at least two transport route modules forms a guiding side on a side of the transport route module lying in a transverse direction oriented transverse to the longitudinal direction and the transport unit is mounted in a guided manner on the guiding side and is arranged to be movable in the longitudinal direction on the guiding side, and
at least one of a single-sided route section having transport route modules on only one side or a two-sided route section having transport route modules on both sides, wherein, in the two-sided route section the guiding sides of transport route modules are arranged on the two sides facing each other,
wherein the at least two transport route modules each have on a respective guiding side a starting point and an ending point, which are situated on grid corner of an (a×a) grid having a predetermined grid length a and grid coordinates (p, q), wherein p, q are whole numbers,
wherein, in the two-sided route section, in a transverse direction between the at least two transport route modules, an intermediate space is provided and the transport unit is arranged at least partially in the intermediate space, whereby midway of the intermediate space in the transverse direction, a movement path is formed which the transport unit follows when moving in the longitudinal direction by the guidance on the transport route modules and the movement path is arranged by the arrangement of the transport route modules in the transverse direction at a distance of (r·a) from the starting point and ending point, wherein r is an odd, whole number,
wherein at least one transport route module is designed as a 90° curve with one of an outward guiding side, with a starting point or ending point at the grid coordinates p=q=0 and the ending point or starting point at the grid coordinates p=(L−r) and preferably q≠0 or an inward guiding side, with a starting point or ending point at the coordinates p=q=0 and the ending point or starting point at the grid coordinates p=(L+r) and q≠0.

4. The transport route according to claim 3 , wherein at least one of:
for the outward guiding side, the starting point or ending point is at the grid coordinates p=q=0 and the ending point or starting point is at the grid coordinates p=(L−r) and q=(L−r), or
for the inward guiding side, the starting point or ending point is at the coordinates p=q=0 and the ending point or starting point is at the grid coordinates p=(L+r) and q=(L+r).

5. A transport route of a long stator linear motor along which a transport unit of the long stator linear motor is movable in a longitudinal direction, comprising:
at least two transport route modules that are arranged adjacent to each other in longitudinal direction, wherein each of the at least two transport route modules forms a guiding side on a side of the transport route module lying in a transverse direction oriented transverse to the longitudinal direction and the transport unit is mounted in a guided manner on the guiding side and is arranged to be movable in the longitudinal direction on the guiding side, and
at least one of a single-sided route section having transport route modules on only one side or a two-sided route section having transport route modules on both sides, wherein, in the two-sided route section, the guiding sides of transport route modules are arranged on the two sides facing each other,
wherein the at least two transport route modules each have on a respective guiding side a starting point and an ending point, which are situated on grid corner of an (a×a) grid having a predetermined grid length a and grid coordinates (p, q), wherein p, q are whole numbers,
wherein, in the two-sided route section, in a transverse direction between the at least two transport route modules, an intermediate space is provided and the transport unit is arranged at least partially in the intermediate space, whereby midway of the intermediate space in the transverse direction, a movement path is formed which the transport unit follows when moving in the longitudinal direction by the guidance on the transport route modules and the movement path is arranged by the arrangement of the transport route modules in the transverse direction at a distance of (r·a) from the starting point and ending point, wherein r is an odd, whole number,
