Abstract

A transport system for containers in the beverage industry, with a first container conveyor including a conveyor belt for conveying the containers, and a lubrication system including an applicator for applying a lubricant to the conveyor belt of the first container conveyor, wherein the transport system comprises a second container conveyor with a further conveyor belt for conveying the containers, and the lubrication system includes a mobile robot which has the applicator arranged thereon and a floor-supported undercarriage, for applying the lubricant in an automated selectively to the conveyor belt of the first container transporter or the conveyor belt of the second container conveyor.

First claim

The invention claimed is:

1. A transport system for containers in the beverage industry, with
a first container conveyor including a conveyor belt for conveying the containers, and
a lubrication system including an applicator for applying a lubricant to the conveyor belt of the first container conveyor,
wherein
the transport system comprises a second container conveyor with a further conveyor belt for conveying the containers,
the lubrication system includes a mobile robot, wherein the mobile robot has the applicator arranged thereon and a floor-supported undercarriage for applying the lubricant in an automated manner selectively to the conveyor belt of the first container conveyor or the conveyor belt of the second container conveyor, and
the mobile robot includes a control unit for controlling both the floor-supported undercarriage and the applicator, and wherein the mobile robot is configured to both move autonomously in the transport system via the floor-supported undercarriage and to autonomously move the applicator for applying the lubricant, wherein the lubrication system includes a friction coefficient measuring device arranged on the mobile robot and used for ascertaining a friction coefficient of the conveyor belts of the first and second container conveyors, wherein the friction coefficient measuring device communicates with a database for retrieving nominal friction coefficients of different container types therefrom and/or for determining the nominal friction coefficient on a basis of similar container types.

2. The transport system according to claim 1 , wherein the mobile robot includes a controllable articulated arm for the applicator so as to move the applicator relative to the first and second container conveyors in various application directions and/or to various application positions.

3. The transport system according to claim 2 , wherein a friction coefficient measuring device includes a contact element arranged on the controllable articulated arm and/or wherein the controllable articulated arm and/or the friction coefficient measuring device is configured to press the contact element with a predetermined force against the respective conveyor belts of the first and second container conveyors by using control currents for controllable joints of the articulated arm.

4. The transport system of claim 2 , wherein the controllable articulated arm is connected at its base to a box-like structure, wherein the floor-supported undercarriage is arranged on a lower end of the box-like structure.

5. The transport system according to claim 1 , wherein the applicator includes at least one nozzle for distributing the lubricant on the conveyor belts of the first and second container conveyors.

6. The transport system according to claim 1 , wherein the lubrication system includes a storage tank and/or a feed pump for the lubricant, which are arranged on the mobile robot.

7. The transport system of claim 1 , wherein the lubricant is a dry lubricant.

8. The transport system of claim 1 , wherein the floor-supported undercarriage of the mobile robot is steerable, so that it can move along curved paths of movement on a floor.

9. The transport system of claim 1 , wherein the floor-supported undercarriage includes wheels, rollers, track and/or crawler chains.

10. A lubrication method for a transport system for containers in the beverage industry, wherein the containers are conveyed with a conveyor belt of a first container conveyor, and wherein a lubricant is applied to the conveyor belt of the first container conveyor by means of an applicator of a lubrication system,
wherein
by means of a floor-supported undercarriage, the applicator is moved in an automated manner from the first container conveyor to a second container conveyor through a mobile robot, so as to apply the lubricant by the applicator to a conveyor belt of at least a second container conveyor, wherein the mobile robot includes a control unit for controlling both the floor-supported undercarriage and the applicator, and wherein the mobile robot is configured to both move autonomously in the transport system via the floor-supported undercarriage and to autonomously move the applicator for applying the lubricant, wherein the lubrication system includes a friction coefficient measuring device arranged on the mobile robot and used for ascertaining a friction coefficient of the conveyor belts of the first and second container conveyors, wherein the friction coefficient measuring device communicates with a database for retrieving nominal friction coefficients of different container types therefrom and/or for determining the nominal friction coefficient on a basis of similar container types.

11. The lubrication method according to claim 10 , wherein an application direction and/or position of the applicator is changed by a controllable articulated arm.

12. The lubrication method according to claim 11 , wherein a contact element of the friction coefficient measuring device is pressed against the conveyor belt of the first container conveyor and/or against the conveyor belt of the second container conveyor with a predetermined force, and at least one friction coefficient for the first and/or second container conveyor is determined in this way, and wherein it is determined on the basis of the at least one friction coefficient whether lubrication of the first and/or second container conveyor will be necessary.

13. The lubrication method according to claim 12 , wherein friction coefficients for the conveyor belt of the first container conveyor and/or the second container conveyor are determined sectionwise with the contact element, and wherein, depending thereon, the lubricant is applied to the conveyor belt of the first container conveyor and/or the second container conveyor by the applicator with dosages varying from one section to a next section.

14. The lubrication method of claim 12 , wherein if it is determined by the control unit on the basis of the at least one friction coefficient that lubrication of the first and/or second container conveyor will be necessary, further determining by the control unit when the lubrication of the first and/or second container conveyor will be necessary on the basis of the friction coefficient.

15. The lubrication method of claim 11 , wherein the controllable articulated arm is connected at its base to a box-like structure, wherein the floor-supported undercarriage is arranged on a lower end of the box-like structure.

16. The lubrication method according to claim 10 , wherein the lubricant is a dry lubricant.

17. The lubrication method of claim 10 , wherein the floor-supported undercarriage of the mobile robot is steerable, so that it can move along curved paths of movement on a floor.

18. The lubrication method of claim 10 , wherein the floor-supported undercarriage includes wheels, rollers, track and/or crawler chains.
