Abstract

A device and a method for removing objects from a moving transport device having objects standing in a row thereon, including a removing device for pushing and thus removing selected objects at a right angle or any other angle with respect to the direction of travel of the transport device. The removing device is formed by a position-controlled linear actuator.

Claims

1. A device for removing objects from a moving transport device having objects standing in a row thereon, comprising:

at least one removing line; and

a removing device for pushing and thus removing selected objects in a lateral direction with respect to a direction of travel of the transport device, the transport device being a conveyor, the removing device including a position-controlled linear actuator and a pusher to push the selected objects in the lateral direction from the conveyor onto the at least one removing line, the at least one removing line including a first removing line returning the objects to a cleaning machine if the objects are soiled and a second removing line serving to collect all objects no longer suitable for further processing.

2. The device as recited in claim 1 wherein the linear actuator includes a position-controlled electric linear motor.

3. The device as recited in claim 1 wherein the linear actuator is coupled to a controller allowing presetting of various movement parameters of the linear actuator.

4. The device as recited in claim 3 wherein the controller controls total travel, speed of travel and/or acceleration of the linear actuator.

5. The device as recited in claim 3 wherein the controller varies the movement parameters of the linear actuator during movement of the linear actuator.

6. The device as recited in claim 3 further comprising a sensor coupled to the controller, the sensor for detecting parameters concerning weight and/or center of gravity of the objects.

7. The device as recited in claim 1 wherein the linear actuator is initializable prior to start-up and/or on the fly.

8. The device as recited in claim 1 wherein a following error of the linear actuator is detectable.

9. The device as recited in claim 1 wherein a position of the linear actuator is adjustable during operation.

10. The device as recited in claim 9 wherein the positional adjustment is controllable by a controller, depending on detected sensor values with respect to parameters of the objects depending on weight and/or center of gravity and/or size.

11. The device as recited in claim 1 wherein the objects comprise beverage containers and/or bottles pushable in the lateral direction from the transport device.

12. A device for removing objects from a conveyor having objects standing in a row thereon, comprising:

a controller;

a sensor connected to the controller for selecting objects to be removed from the conveyor;

a first removing line and a second removing line; and

a position-controlled linear pusher connected to the controller for pushing selected objects in a lateral direction with respect to a direction of travel of the conveyor onto the first and second removing lines, the first removing line returning the objects to a cleaning machine if the objects are soiled and the second removing line serving to collect all objects no longer suitable for further processing.

13. The device as recited in claim 12 wherein the first and second removing lines are arranged parallel to the conveyor at the pusher.

14. The device as recited in claim 12 wherein the controller allows presetting of various movement parameters of the linear actuator.

15. The device as recited in claim 12 wherein the controller controls total travel, speed of travel and/or acceleration of the linear actuator.

16. The device as recited in claim 12 wherein the controller varies the movement parameters of the linear actuator during movement of the linear actuator.

17. The device as recited in claim 12 wherein the sensor detects parameters concerning weight and/or center of gravity of the objects.

18. The device as recited in claim 12 wherein the linear actuator is initializable prior to start-up and/or on the fly.

19. The device as recited in claim 12 wherein a following error of the linear actuator is detectable.

20. The device as recited in claim 12 wherein the objects comprise beverage containers and/or bottles pushable in the lateral direction from the transport device
