Abstract

A container discharge apparatus for discharging containers from a mass flow conveyor and for separating the containers, the apparatus comprising the following: adjoining a mass flow conveyor, a first group of a plurality of first conveyors arranged in parallel which can be driven in a first direction transverse to the transport direction of the mass flow conveyor and are designed to separate containers and to convey them in the first direction; adjoining the first group so as to be parallel therewith, a second group of a plurality of parallel second conveyors arranged in parallel which can be driven in a second direction and are designed to convey the separated conveyors in the second direction opposite the first direction; one or more third conveyors, the third conveyor(s) being designed to transport away the separated containers. The invention also relates to a method for operating the container discharge apparatus.

First claim

1 . A container discharge apparatus for discharging containers from a mass flow conveyor and for separating the containers, wherein the container discharge apparatus comprises:
downstream of the mass flow conveyor, a first group of a plurality of first conveyors arranged in parallel, which can be driven in a first direction transverse to a transport direction of the mass flow conveyor and are designed to separate containers and to convey them in the first direction, following in parallel the first group of the plurality of first conveyors arranged in parallel, a second group of a plurality of second conveyors arranged in parallel, which can be driven in a second direction and are designed to convey the separated containers in the second direction, which is opposite the first direction, and one or more third conveyors, wherein the one or more third conveyors are designed to transport the separated containers.

2 . The container discharge apparatus according to claim 1 , wherein a concave railing is provided at an end of the plurality of first conveyors arranged in parallel and at a beginning of at least some of the plurality of second conveyors arranged in parallel above transport surfaces, wherein, for example, the concave railing comprises a curve that describes an angle in an angular range of 135° to 195°.

3 . The container discharge apparatus according to claim 2 , wherein a straight railing is provided above the transport surfaces between the first group and the second group, which railing is designed in such a way that there is a transition region for containers between the first group and the second group.

4 . The container discharge apparatus according to claim 3 , wherein the transition region is divided by a further concave railing into a first partial transition region and a second partial transition region, wherein, for example, the further concave railing is arranged partially above at least some of the plurality of first conveyors arranged in parallel and at least some of the plurality of second conveyors arranged in parallel, wherein for example the further concave railing is also designed to taper in triangular fashion on a surface opposite a concave surface.

5 . The container discharge apparatus according to claim 3 , wherein a further railing is provided above the transport surfaces of the plurality of second conveyors arranged in parallel, wherein for example the further railing leaves the transition region free, wherein for example the straight railing merges into the further railing, wherein for example the further railing is straight or comprises steps.

6 . The container discharge apparatus according to claim 1 , wherein the plurality of first conveyors arranged in parallel each comprise individual transport surfaces which are arranged without steps in adjacent regions, wherein the individual transport surfaces enclose angles of 0° to −30°, inclusive, with a plane perpendicular to a direction of action of gravity.

7 . The container discharge apparatus according to claim 6 , wherein the plurality of second conveyors arranged in parallel each comprise transport surfaces which are arranged without steps in adjacent regions, wherein the individual transport surfaces enclose angles of 0° to −30°, inclusive, with a plane perpendicular to the direction of action of gravity.

8 . The container discharge apparatus according to claim 6 , wherein the plurality of second conveyors arranged in parallel each comprise transport surfaces which are arranged without steps in adjacent regions, wherein the individual transport surfaces enclose angles of 0° to +30°, inclusive, with a plane perpendicular to the direction of action of gravity.

9 . The container discharge apparatus according to claim 1 , wherein a first number of the plurality of second conveyors arranged in parallel each comprise individual first transport surfaces which are arranged without steps in adjacent regions, wherein the individual first transport surfaces enclose angles of 0° to −30°, inclusive, with a plane perpendicular to a direction of action of gravity, and wherein a second number of the plurality of second conveyors arranged in parallel each comprise individual second transport surfaces, which are arranged without steps in adjacent regions, wherein the individual second transport surfaces enclose angles of 0° to +30°, inclusive, with a plane perpendicular to the direction of action of gravity, wherein for example at least one of the plurality of second conveyors arranged in parallel is provided with its transport surface between the first number and the second number of the plurality of second conveyors arranged in parallel, and its transport surface encloses an angle of 0° with a plane perpendicular to the direction of action of gravity.

10 . The container discharge apparatus according to claim 1 , wherein the container discharge apparatus comprises at least one ejection device for containers that comprises for example at least one flexible element and at least one collecting device for ejected containers, wherein the at least one flexible element is provided spaced above at least some of the plurality of first conveyors arranged in parallel and/or above at least some of the plurality of second conveyors arranged in parallel, wherein for example the at least one collecting device is provided below at least some of the plurality of first conveyors arranged in parallel and/or below at least some of the plurality of second conveyors arranged in parallel, wherein for example the at least one flexible element is designed to be adjustable in height.

11 . The container discharge apparatus according to claim 1 , wherein, between the second group of the plurality of second conveyors arranged in parallel and the one or more third conveyors, following in parallel the second group of the plurality of second conveyors arranged in parallel, there is provided a further group of a plurality of fourth conveyors arranged in parallel, which can be driven in the first direction and are designed to convey containers in the first direction.

12 . The container discharge apparatus according to claim 1 , wherein, between the second group of the plurality of second conveyors arranged in parallel and the one or more third conveyors, there is provided at least one intermediate conveyor which is arranged transversely to the second direction.

13 . The container discharge apparatus according to claim 1 , wherein a number of the third conveyors is smaller or larger than a number of the second conveyors, or wherein the number of the third conveyors is equal to the number of the second conveyors.

14 . A method for operating the container discharge apparatus according to claim 1 .
