Abstract

The invention provides a livestock feed-displacing device and system, with a grab bucket which can be positioned above a feed kitchen with feed positions by a control unit, wherein the control unit is designed to compose an amount of animal feed from feed material provided in the feed kitchen by positioning the grab bucket at a grabbing position, grabbing livestock feed underneath said grabbing position, positioning the grab bucket at a desired feed-unloading point, such as in a feed wagon, and unloading the grabbed livestock feed at the feed-unloading point, wherein the control unit is designed to earmark, if at least one predetermined clearing-up criterion has been met, livestock feed in the feed kitchen as waste to be removed and to make the device carry out a clearing-up operation, wherein the clearing-up operation comprises the removal of the livestock feed at said feed position by displacing it to another position in the feed kitchen.

First claim

The invention claimed is:

1. Device for displacing livestock feed, comprising:
a feed gripping device, and
a control unit for the feed gripping device,
wherein the feed gripping device comprises a grab bucket which can be operated by the control unit and can be positioned with a vertical and at least one horizontal degree of freedom above a feed kitchen, wherein the feed kitchen comprises at least one feed position on which at least one type of livestock feed is provided,
wherein the control unit is designed to receive a feed order, comprising information for composing an amount of animal feed from one or more types of livestock feed provided in the feed kitchen, and for carrying out the following one or more times on the basis of the feed order:
positioning the grab bucket at a desired grabbing position with respect to the feed kitchen,
operating the grab bucket to make the grab bucket grab at least a part of the livestock feed situated underneath said grabbing position,
positioning the grab bucket at a desired feed-unloading point for composing the amount of animal feed to be composed which is to be fed to animals, and
operating the grab bucket to make the grab bucket unload the livestock feed which the grab bucket has grabbed at the feed-unloading point,

wherein the control unit is furthermore designed to earmark, if at least one predetermined clearing-up criterion has been met, the livestock feed for a clearing-up operation at least at part of at least one feed position in the feed kitchen which does not form part of a feed order, and to make the device carry out a clearing-up operation,
wherein the clearing-up operation comprises the removal of at least part of the livestock feed on the part of said feed position by displacing said part of the livestock feed to another position in the feed kitchen.

2. Device according to claim 1 , wherein the clearing-up operation comprises a combining operation, comprising grabbing at least a part of the livestock feed on the part of said feed position and displacing the grabbed livestock feed either to another part of said feed position or to another feed position on which livestock feed of the same type as the grabbed livestock feed is provided.

3. Device according to claim 1 , wherein the clearing-up operation is a cleaning operation and removing the livestock feed comprises grabbing, displacing and unloading the livestock feed at a feed-waste collecting position.

4. Device according to claim 3 , wherein the cleaning operation comprises the removal of a predetermined upper part of the livestock feed at a feed position.

5. Device according to claim 1 , wherein the another position in the feed kitchen is a feed-waste collecting position which is different from the feed-unloading point.

6. Device according to claim 1 , wherein the at least one clearing-up criterion includes that the device is not busy carrying out a feed order.

7. Device according to claim 1 , wherein the at least one clearing-up criterion includes that the control unit does not contain any unfinished feed order, and/or that the control unit only contains one or more feed orders which do not have to be started within a predetermined time.

8. Device according to claim 1 , wherein the at least one clearing-up criterion includes that the control unit has not received a feed order for at least a predetermined time period.

9. Device according to claim 1 , wherein the at least one clearing-up criterion includes that the control unit contains a clearing-up instruction which is still to be carried out.

10. Device according to claim 1 , wherein the at least one clearing-up criterion includes a removal condition, and wherein the device further comprises a measuring device which is designed to detect, at least for one feed position, whether said feed position meets the removal condition.

11. Device according to claim 10 , wherein the removal condition includes that a value of a predetermined parameter of the livestock feed at said at least one feed position, or a part thereof, meets a predetermined removal criterion.

12. Device according to claim 11 , wherein the predetermined parameter comprises an average height or maximum height of the livestock feed at the feed position, or a part thereof, and wherein the removal condition includes that the parameter value is smaller than a first threshold height.

13. Device according to claim 11 , wherein the parameter comprises a residual amount of livestock feed at the feed position, or a part thereof, and wherein the removal condition includes that the parameter value is smaller than a first threshold amount.

14. Device according to claim 11 , comprising a measuring device designed to measure the value of the predetermined parameter for one or more feed positions.

15. Device according to claim 14 , wherein the measuring device is provided on the feed gripping device.

16. Device according to claim 14 , wherein the measuring device comprises a height-measuring and/or distance-measuring device.

17. Device according to claim 16 , wherein the measuring device comprises a laser distance-measuring device, an ultrasound distance-measuring apparatus and/or a 3D-camera.

18. Device according to claim 14 , wherein the measuring device is designed to scan a feed position, preferably during displacement of the feed gripping device.

19. An assembly comprising:
a feed kitchen, and
a device for displacing livestock feed, the device further comprising:
a feed gripping device, and
a control unit for the feed gripping device,

wherein the feed gripping device comprises a grab bucket which can be operated by the control unit and can be positioned with a vertical and at least one horizontal degree of freedom above a feed kitchen, wherein the feed kitchen comprises at least one feed position on which at least one type of livestock feed is provided,
wherein the control unit is designed to receive a feed order, comprising information for composing an amount of animal feed from one or more types of livestock feed provided in the feed kitchen, and for carrying out the following one or more times on the basis of the feed order:
positioning the grab bucket at a desired grabbing position with respect to the feed kitchen,
operating the grab bucket to make the grab bucket grab at least a part of the livestock feed situated underneath said grabbing position,
positioning the grab bucket at a desired feed-unloading point for composing the amount of animal feed to be composed which is to be fed to animals, and
operating the grab bucket to make the grab bucket unload the livestock feed which the grab bucket has grabbed at the feed-unloading point,

wherein the control unit is furthermore designed to earmark, if at least one predetermined clearing-up criterion has been met, the livestock feed for a clearing-up operation at least at part of at least one feed position in the feed kitchen which does not form part of a feed order, and to make the device can out a clearing-up operation,
wherein the clearing-up operation comprises the removal of at least part of the livestock feed on the part of said feed position by displacing said part of the livestock feed to another position in the feed kitchen, and
wherein the feed kitchen comprises at least one feed position for grabbing material provided in the feed kitchen.

20. An assembly according to claim 19 , furthermore comprising an autonomous clearing device, which is designed to remove at least part of the material in the feed kitchen under the control o
