Abstract

A transport system for containers includes a plurality of vehicles configured to be driven independently of each other. A guiding device is configured to guide the vehicles in a circulating manner. A plurality of mold shells are configured to encompass a side wall of the containers about a partial circumferential area of the side wall, the plurality of mold shells being mounted on respective ones of the plurality of vehicles so as to receive the containers between adjacent mold shells of adjacent vehicles and transport them.

Claims

1. A transport system for containers comprising:

a plurality of vehicles configured to be driven independently of each other;

a guiding device configured to guide the vehicles in a circulating manner;

a plurality of mold shells configured to encompass a side wall of the containers about a partial circumferential area of the side wall, the plurality of mold shells being mounted on respective ones of the plurality of vehicles so as to receive the containers between adjacent mold shells of adjacent vehicles and transport them; and

active driving devices for the plurality of vehicles disposed on the guiding device,

wherein the plurality of vehicles include reactive driving devices cooperating with respective ones of the active driving devices, and

wherein the active driving devices include linear motor modules cooperating with permanent magnets of the reactive driving devices.

2. The transport system according to claim 1, wherein the containers are plastic bottles and the plurality of vehicles include slides.

3. The transport system according to claim 1, wherein the guiding device is longer than the plurality of vehicles so as to form at least one non-circulating gap between respective ones of the plurality of vehicles for at least one of introducing and withdrawing the containers during the circulating of the plurality of vehicles.

4. The transport system according to claim 1, wherein two of the plurality of mold shells are mounted on each one of the plurality of vehicles, the two of the plurality of mold shells being opposed to each other relative to a transport direction of the containers.

5. The transport system according to claim 1, wherein the plurality of vehicles are configured to be movable against each other so as to encompass a full circumference of a respective one of the containers between two of the plurality mold shells of adjacent ones of the plurality of vehicles.

7. The transport system according to claim 1, wherein the plurality of mold shells are configured to externally support the encompassed containers against a filling pressure for the purpose of carbonation.

8. The transport system according to claim 1, wherein the plurality of mold shells are each formed as a blow mold half.

9. The transport system according to claim 1, wherein the plurality of mold shells are configured to laterally hold the encompassed containers underneath a neck portion of the containers.

10. A method for the transport of containers using transport system according to claim 1, the method comprising:

encompassing, by respective ones of the plurality of mold shells, a side wall of the containers about a partial circumferential area of the side wall;

transporting the encompassed containers between the respective ones of the mold shells disposed on adjacent ones of the plurality of vehicles; and

moving the adjacent ones of the plurality of vehicles apart so as to remove the containers from the transport system.

11. The method according to claim 10, further comprising at least one of blow molding, filling and closing the containers during the transporting.

12. The method according to claim 10, wherein the transporting is performed with a speed of circulation of the plurality of vehicles that is varied relative to leading and following ones of the plurality of vehicles so as to form a non-circulating gap between respective ones of the plurality vehicles into which the containers are at least one of loaded and unloaded.

6. A transport system for containers comprising:

a plurality of vehicles configured to be driven independently of each other;

a guiding device configured to guide the vehicles in a circulating manner;

a plurality of mold shells configured to encompass a side wall of the containers about a partial circumferential area of the side wall, the plurality of mold shells being mounted on respective ones of the plurality of vehicles so as to receive the containers between adjacent mold shells of adjacent vehicles and transport them; and

a locking device disposed on each of the plurality of mold shells configured to secure the encompassed containers against rotating about their main axis.

13. A method for the transport of containers using the transport system according to claim 6, the method comprising:

encompassing, by respective ones of the plurality of mold shells, a side wall of the containers about a partial circumferential area of the side wall;

transporting the encompassed containers between the respective ones of the mold shells disposed on adjacent ones of the plurality of vehicles; and

moving the adjacent ones of the plurality of vehicles apart so as to remove the containers from the transport system.
