Abstract

An apparatus for bundling containers includes a linear conveyor, a guide element, conveying elements, and application elements, each of which applies adhesive to a portion of a container surface, The conveying elements are driven and controllable to travel along the conveyor and to circulate along the guide element. Each conveying element has a container guide that rotates relative to the conveying element. The guide element has a feed strand with central, transition, and end sections that merge into each other. The central section is further from the central axis than the end section. The distance from end section to central axis is such that containers circulating on the end section are brought into contact with adhesive on a surface of an adjacent container.

First claim

Having described the invention, and a preferred embodiment thereof, what is claimed as new, and secured by Letters Patent is:

1. An apparatus for making bundles of containers from containers that have arrived in a wide container stream that has been converted into multiple one lane container streams by formation of lanes, said bundles of containers being formed by combining partial bundles into subsequent bundles using at least one separating-and/or-compacting unit for separating and compacting a predetermined number of said containers as said containers move along a conveying direction, said apparatus comprising a first linear conveyor, a guide element, conveying elements, and coating elements, wherein each coating element is configured to apply adhesive to a portion of a container surface, wherein said conveying elements travel along said first linear conveyor, wherein said conveying elements are driven and controlled to circulate along said guide element, wherein each conveying element comprises a container guide, wherein said container guide is rotatable relative to said conveying element, wherein said guide element comprises a feed strand, wherein said feed strand comprises a central section, a transition section, and an end section, wherein said central section merges into said transition section, wherein said transition section merges into said end section, wherein said central section is separated from a central axis by a first distance, wherein said end section is separated from said central axis by a second distance, wherein said second distance is less than said first distance, wherein said second distance is selected such that containers circulating on said end section are brought into contact with adhesive on a surface of an adjacent container, and wherein said surface has a normal vector that crosses a direction in which said adjacent container is moving.

2. The apparatus of claim 1 , wherein each of said conveying elements comprises a vertically oriented chute.

3. The apparatus of claim 1 , wherein each of said conveying elements can be controlled and driven separately from other conveying elements.

4. The apparatus of claim 1 , further comprising a linear drive, wherein each of said conveying elements can be driven and controlled by said linear drive.

5. The apparatus of claim 4 , wherein said linear drive comprises an electromagnetic direct drive.

6. The apparatus of claim 1 , wherein said guide element comprises a rear strand, and wherein said apparatus further comprises a deflection section that is arranged between said rear strand and said feed strand.

7. The apparatus of claim 1 , wherein each of said conveying elements moves a single vertically-oriented container.

8. The apparatus of claim 1 , wherein each of said conveying elements is configured to move a container by holding on a top thereof such that said container sways freely.

9. The apparatus of claim 1 , wherein each of said conveying elements is configured to move a container by holding on a top thereof such that said container stands upright on a conveyor along at least a partial section thereof.

10. The apparatus of claim 1 , wherein each of said conveying elements comprises a top guide and a contact device for a container, wherein said top guide and said contact device are controllable independently of each other, and wherein said contact device is rotatable relative to said conveying element.

11. The apparatus of claim 10 , wherein said contact device comprises a rotary plate.

12. The apparatus of claim 1 , wherein said transition section comprises a domed transition section.

13. The apparatus of claim 12 , wherein said transition section is domed in a manner such that said transition section approaches said axis.

14. The apparatus of claim 1 , further comprising a second linear conveyor, wherein said second linear conveyor is identical in structure to said first linear conveyor, wherein said first and second linear conveyors are arranged opposite each other relative to said central axis, and wherein said coating elements are arranged opposite each other between central sections of said first and second linear conveyors.

15. The apparatus of claim 14 , wherein said first and second linear conveyors are movable relative to each other.
