Abstract

A divider arrangement, guide device, for guiding packages between at least two conveyor belts, and method of controlling the same is provided.

First claim

The invention claimed is:

1. A divider arrangement, arranged in connection to a package transporting conveyor belt, for moving incoming packages from a first conveyor belt to a second conveyor belt, wherein the first conveyor belt is arranged parallel and adjacent to the second conveyor belt, comprising:
a guiding device including a pair of lower guide rails between which the packages are transportable by the first conveyor belt and/or the second conveyor belt; and
wherein the guiding device is rigidly attached to a guiding belt being connected to two electric motors in an H-bot assembly for controllably moving the pair of lower guide rails over the first conveyor belt and second conveyor belt in a plane parallel to a top surface of the first conveyor belt and/or the second conveyor belt.

2. The divider arrangement according to claim 1 , wherein the two electric motors allows for the guiding device to move both longitudinally and laterally in view of direction of movement of the first conveyor belt and/or the second conveyor belt.

3. The divider arrangement according to claim 1 , wherein a sensor is positioned at a distance from the forwardmost end of the pair of lower guide rails, the sensor being configured to detect the presence of a package being transported between the pair of lower guide rails, wherein said distance is not larger than depth of the package in the direction of movement.

4. The divider arrangement according to claim 1 , wherein each of the two electric motors by way of the guiding belt is positioned such that when only one of the electric motors is operating the guiding device is moved in a 45 degree angle in view of the longitudinal axis of the first conveyor belt and/or second conveyor belt.

5. The divider arrangement according to claim 1 , wherein one of the two electric motors is arranged at a position in a forward part of the H-bot assembly, and the other electric motor is arranged in a backward part of the H-bot assembly.

6. The divider arrangement according to claim 1 , wherein the guiding device further comprises a pair of upper guide rails arranged to support the top of the packages and prevent them from tilting when transported on the first conveyor belt and/or second conveyor belt.

7. The divider arrangement according to claim 3 , wherein the guiding device is operable in a first mode, which is activated when the guiding device is positioned at a rearmost position and aligned with either the first conveyor belt or second conveyor belt, such that when the sensor detects a first package to be moved to the other of the first conveyor belt or second conveyor belt, wherein the two electric motors are arranged to accelerate the guiding device by the guiding belt, in a direction parallel to that of the first conveyor belt and/or second conveyor belt and in a forward direction, up to a speed being identical the speed of the first conveyor belt and/or second conveyor belt.

8. The divider arrangement according to claim 7 , wherein the guiding device is operable in a second mode, which is activated once the guiding device has been accelerated to the speed of the first conveyor belt and/or second conveyor belt, wherein the two electric motors are arranged to move the guiding device to the other of the first conveyor belt and/or second conveyor belt by the guiding belt, while maintaining the speed of the guiding device in the longitudinal direction.

9. The divider arrangement according to claim 8 , wherein the two electric motors are arranged to move the guiding device to the other of the first conveyor belt and/or second conveyor belt, while maintaining the speed in the longitudinal direction, before reaching the forwardmost end position of the guiding device.

10. The divider arrangement according to claim 8 , wherein the guiding device is operable in a third mode, which is activated once the guiding device has been moved to the other of the first conveyor belt and/or second conveyor belt, wherein the two electric motors are arranged continue moving the guiding device in a direction parallel to that of the first conveyor belt and/or second conveyor belt at the speed of the first conveyor belt and/or second conveyor belt.

11. The divider arrangement according to claim 10 , wherein the guiding device is operable in a fourth mode, which is activated following the third mode and at the latest once the guiding device has reached its forwardmost position, wherein the two electric motors are arranged move the guiding device in a direction parallel to that of the first conveyor belt and/or second conveyor belt and in a backward direction at a predetermined speed.

12. The divider arrangement according to claim 1 , further comprising a second pair of guide rails, along which the first pair of guide rails of the guiding device is slidable in a direction parallel to the first conveyor belt and/or the second conveyor belt, wherein the guiding device acts as a telescopic extension arm in view of the second pair of guide rails.

13. The divider arrangement according to claim 12 , further comprising a third pair of guide rails being rotatably attached at a forwardmost end to a rearmost end of the second pair of guide rails by a first attachment arrangement and attached at a rearmost end at either side of the package transporting conveyor belt by a second attachment arrangement.

14. The divider arrangement according to claim 13 , wherein each third guide rail of the third pair of guide rails at the position of the first attachment arrangement is provided with an angled slot being provided straight through each of the third guide rails, along which angled slot a rod shaped structure of the first attachment arrangement is slidable, thereby allowing for maintaining a constant distance between the third pair of guide rails when rotated in view of the second attachment arrangement.

15. The divider arrangement according to claim 13 , wherein each second attachment arrangement is configured to allow for a guide rail of the third pair of guide rails to rotate in a plane parallel to a plane of the upper side of the package transporting conveyor belt in relation to said attachment arrangement, thereby allowing a package to be moved move from the package transporting conveyor belt to either the first conveyor belt or the second conveyor belt by rotation of the third pair of guide rails around their respective second attachment arrangement.

16. The divider arrangement according to claim 1 , further comprising a control unit arranged to control the two electric motors and movement of the guiding device according to a desired movement scheme.

17. The divider arrangement according to claim 15 , comprising a control unit arranged to control the two electric motors and movement of the guiding device according to a desired movement scheme, and a sensor positioned at a distance from a forwardmost end of the pair of lower guide rails and configured to detect presence of a package being transported between the pair of lower guide rails, and wherein the control unit is arranged to receive an input signal from the sensor and control the operation of the two electric motors and thereby the movement of the guiding device based on the sensor input signal.

18. The divider arrangement according to claim 15 , wherein the control unit is arranged to receive an input signal comprising information about the speed of the first conveyor belt and/or the second conveyor belt, and control the operation of the two electric motors and thereby the movement of the guiding device based on this speed input signal.
