Abstract

The present disclosure describes a storage and distribution unit for a container filling plant and a method for storing and distributing the containers. A store is provided, which comprises storage areas for containers, the storage areas being distributed in a grid pattern, a container feed for connection to a discharge line section of a filling line, and a container outlet for connection to inspection units. The storage and distribution unit comprises a robot for putting filled containers into storage by transferring them from the container feed to the storage areas as well as for taking the containers out of storage by transferring them from the storage areas to the container outlet. Making use of a programmable control unit, the robot can be controlled for selectively taking the containers out of storage independently of the moment in time at which and/or the sequence in which they have been put into storage.

First claim

What is claimed is:

1. A storage and distribution unit for a container filling plant, comprising:
a store comprising:
a plurality of storage areas for storing a plurality of individual containers, the plurality of storage areas being distributed in a grid pattern;
a container feed for connection to a discharge line section of a filling line; and
a container outlet for connection to a plurality of inspection units; and

a robot operatively coupled to a programmable control unit to:
according to an electronically stored sampling plan, put a plurality of filled containers into the store by transferring the plurality of filled containers from the container feed to the plurality of storage areas; and
according to an electronically stored inspection plan, selectively take the plurality of filled containers out of the store independently of at least one of: a moment in time at which the plurality of filled containers were put into the store, or a sequence in which the plurality of filled containers were put into the store.

2. The storage and distribution unit according to claim 1 , wherein the container feed comprises a conveyor belt for successively providing containers according to a sequence of the electronically stored sampling plan.

3. The storage and distribution unit according to claim 1 , wherein the plurality of storage areas comprises at least eight storage areas.

4. The storage and distribution unit according to claim 1 , wherein the store further comprises at least one replaceable storage insert for providing the plurality of storage areas.

5. The storage and distribution unit according to claim 1 , wherein the container outlet comprises at least one transport path for connection to at least one inspection unit of the plurality of inspection units.

6. The storage and distribution unit according to claim 1 , wherein the container outlet comprises at least one transport path for connection to at least two inspection units of the plurality of inspection units.

7. The storage and distribution unit according to claim 1 , further comprising at least one of a disposal store or a disposal conveyor, wherein the robot is to selectively distribute a faulty container to at least one of the disposal store or the disposal conveyor.

8. The storage and distribution unit according to claim 1 , further comprising a feedback device to provide data feedback between at least one of the plurality of inspection units connected to the container outlet and an inline inspection unit formed upstream of the discharge line section.

9. The storage and distribution unit of claim 1 , wherein the plurality of storage areas comprises at least sixteen storage areas.

10. The storage and distribution unit of claim 1 , wherein:
the electronically stored sampling plan specifies at least one of: a specific number of containers per unit time, a specific number of containers per production batch, or a specific number of containers per number of containers filled; and
the electronically stored inspection plan specifies at least one of: a capacity of the plurality of inspection units, a time required for inspections performed by each inspection unit of the plurality of inspection units, or an availability of each inspection unit of the plurality of inspection units.

11. A container filling plant, comprising:
a storage and distribution unit comprising:
a store comprising:
a plurality of storage areas for storing a plurality of individual containers, the plurality of storage areas being distributed in a grid pattern;
a container feed for connection to a discharge line section of a filling line; and
a container outlet for connection to a plurality of inspection units;

a robot operatively coupled to a programmable control unit to:
according to an electronically stored sampling plan, put a plurality of filled containers into the store by transferring the plurality of filled containers from the container feed to the plurality of storage areas; and
according to an electronically stored inspection plan, selectively take the plurality of filled containers out of the store independently of at least one of: a moment in time at which the plurality of filled containers were put into the store, or a sequence in which the plurality of filled containers were put into the store; and

the plurality of inspection units is to perform at least one of: checking the plurality of filled containers, or checking a filling product contained in the plurality of filled containers, wherein the plurality of inspection units check at least one of the plurality of filled containers or the filing product by at least one of measuring a Brix value of the filling product, measuring a CO 2 content of the filling product, measuring a diet concentration of the filling product, measuring a weight of the filled containers or measuring a closing force of the filled containers.

12. The container filling plant according to claim 11 , wherein the storage and distribution unit and the inspection units are arranged under a protective atmosphere in a laboratory area, which is spatially separated from the filling line.

13. A method for storing and distributing containers in a container filling plant, comprising:
putting, by a robot according to an electronically stored sampling plan, a plurality of filled containers discharged from a filling line into a store by transferring the plurality of filled containers from a container feed to a plurality of storage areas for individual containers, the plurality of storage areas being distributed in a grid pattern; and
selectively taking, by the robot according to an electronically stored inspection plan, the plurality of filled containers out of the store and forwarding the plurality of filled containers taken out of the store to a plurality of inspection units, wherein the containers are selectively taken out of the store independently of at least one of: a moment in time at which the plurality of filled containers were put into the store, or a sequence in which the plurality of filled containers were put into the store.

14. The method according to claim 13 , wherein the electronically stored sampling plan specifies at least one of a specific number of containers per unit time, a specific number of containers per production batch, or a specific number of containers per number of containers filled.

15. The method according to claim 13 , wherein, according to the electronically stored sampling plan, the plurality of filled containers are purposefully discharged from the filling line and made available with an electronic mark and put into storage.

16. The method according to claim 13 , wherein putting the plurality of filled containers into the store further comprises storing and assigning a set of information to the plurality of storage areas, the set of information comprising: a) information for identifying at least one of: the plurality of filled containers, a filling product or a product batch, and b) information for identifying at least one of: time stamps, associated filling unit numbers or associated capping unit numbers.

17. The method according to claim 13 , wherein, according to at least one of the electronically stored inspection plan or an availability of associated inspection units, the plurality of filled containers are taken out of storage and, in so doing, are distributed to at least one of parallel transport paths or parallel inspection units.

18. The method according to claim 13 , further comprising:
inspecting at least one of the plurality of filled containers or a fi
