Abstract

For a long stator linear motor comprising a switch and secure guidance of the transport vehicles in the direction of movement along the transport track, it is provided that the transport vehicle (Tn) is force-guided, at least in sections, in the direction of movement (x) outside the switch (W), and at least one one-sided track section (2d) is provided on the transport track (2), along which a vehicle guide element (7) only on one side of the transport track (2) interacts with the track guide element (6) on the assigned side of the transport track (2) for the mechanical forced guidance in the direction of movement (x), and the forced guidance in the direction of movement (x) in the transverse direction (y) is canceled in the region of the switch (W).

First claim

The invention claimed is:

1. A long stator linear motor, comprising:
a transport track along which at least one transport vehicle is movably arranged in a direction of movement, the transport track comprising a track guide element;
a vehicle guide element located on opposite sides of the at least one transport vehicle so as to be separated in a direction transverse to the direction of movement;
at least one vehicle guide element interacting with the track guide element to guide the transport vehicle along the transport track; and
the transport track further comprising at least one switch, which connects a first track section of the transport track to a second track section of the transport track, the switch being structured to allow the transport vehicle, in a region of the switch, to switch, in the direction traverse to the direction of movement, from the first track section to the second track section, or from the second track section to the first track section,
wherein, outside of the switch, the at least one transport vehicle is moved via mechanical forced guidance, at least in sections, in the direction of movement,
wherein the transport track further comprises at least one one-side track section, along which the vehicle guide element only on one side of the at least one transport vehicle interacts with the track guide element on an assigned side of the transport track for the mechanical forced guidance in the direction of movement,
wherein, the first track section and the second track section diverge at the least one switch and, in the region of the at least one switch, track guide elements interact with the vehicle guide elements on the opposite sides of the at least one vehicle, and the mechanical forced guidance in the direction of movement is canceled in the transverse direction.

2. The long stator linear motor according to claim 1 , wherein the first track section in the direction of movement of the transport vehicle in front of and/or after the switch is designed as a one-sided track section.

3. The long stator linear motor according to claim 2 , wherein the second track section is designed as a second one-sided track section.

4. The long stator linear motor according to claim 1 , wherein the track guide element for guiding the transport vehicle in the transverse direction is removed in the region of the switch.

5. The long stator linear motor according to claim 1 , wherein the vehicle guide element for guiding the transport vehicle in the transverse direction is adjustable in the region of the switch, so as to cancel the interaction between the vehicle guide element and the assigned track guide element for guiding the transport vehicle in the transverse direction.

6. The long stator linear motor according to claim 1 , wherein the second track section is designed as a one-sided track section.
