Document Type and Number:
WIPO Patent Application WO/2018/091533
Kind Code:
A4
Abstract:
The invention relates to a portioning device for packaging of food products (3) in a portion carrier, comprising positioning device and gripping device (1), which gripping device comprises first and second articulating jaws (12a, 12b) having first and second ends that together with a belt or table (5) for a food product (3) define an opening between said jaws (12a, 12b) arranged to grip the food product laying on the belt or table (5), wherein said first and second jaws (12a, 12b) are articulately arranged in order to be movable between at least two relative positions, one holding position and one open position, wherein the portioning device also comprises a cutting device (2) arranged at said first and/or second ends of said first and second articulating jaws (12a, 12b), and wherein said cutting device (2) is arranged to use the belt/table (5) as support for cutting. The invention also relates to a method for packaging of food products by use of the portioning device.

AMENDED CLAIMS

received by the International Bureau on 11 May 2018 (11.05.2018)

1. A portioning device for packaging of food products (3) in a portion carrier, comprising positioning device and gripping device (1), which gripping device comprises first and second articulating jaws (12a, 12b) having first and second ends that together with a belt or table (5) for a food product (3) define an opening between said jaws (12a, 12b) arranged to grip the food product laying on the belt or table (5), wherein said first and second jaws (12a, 12b) are articulately arranged in order to be movable between at least two relative positions, one holding position and one open position, characterized in that the device also comprises a cutting device (2) arranged at said first and/or second ends of said first and second articulating jaws (12a, 12b), and wherein said cutting device (2) is arranged to use the belt/table (5) as support for cutting.

2. A portioning device according to claim 1, characterized in that said cutting device (2) comprises a knife blade (22) arranged to cut along a plane that is substantially parallel to a side edge (120) or corner edge (121, 122) of at least one of said jaws (12a, 12b).

3. A portioning device according to any of the preceding claims, characterized in that said cutting device (2) is arranged to cut in a direction at an angle (a) to the plane of said belt or table (5), preferably at an angle of about 30-60°, even more preferred 40-50° and most preferred about 45°, to the plane of said belt or table.

4. A portioning device according to any of the preceding claims, characterized in that said cutting device (2) is pivotally arranged around a vertical axis of rotation (C) that is perpendicular to the plane of said belt or table (5), up to an angle of about 30-60°, even more preferred 40-50° and most preferred about 45° in relation to said opening between said jaws (12a, 12b).

5. A portioning device according to claim 3 or 4, , characterized in that said cutting device (2) is releasably fixedly adjustable by means of mechanical means (25) in different positions.

6. A portioning device according to any of the preceding claims, characterized in that said cutting device (2) is mounted at and operable by a push rod (21) to perform a linear motion.

7. A portioning device according to any of claims 1-3, characterized in that said cutting device (2) comprises a pair of cutting scissors (22a, 22b) mounted at said first and second jaws (12a, 12b), which cutting scissors is open in said open position of said first and second jaws and closed in said holding position of said first and second jaws.

8. A portioning device according to any of the preceding claims, characterized in that said positioning device is arranged to position said gripping device (1) in relation to a portion carrier such that at least parts of said gripping device are at a level below the top surface of at least one first food product which has already been placed at said portion carrier.

9. A method for packaging of food products (3) comprising:

i. gripping the food product (3) laying on a belt or table (5), by a gripping device (1) having first and second articulately arranged jaws (12a, 12b) having first and second ends that together with said belt or table (5) define an opening between said jaws

(12a, 12b), in order to hold said food product (3) in a holding position;

ii. raising said food product (3) to be moved to a portion carrier by said gripping device iii. moving said food product (3) to the selected portion carrier and

iv. releasing said food product (3) to the portion carrier;

characterized in that, in conjunction with step "I" or step "ii", a piece (3A) of said food product (3) is cut off by a cutting device (2) arranged at said first and/or second ends (120) of said first and second jaws (12a, 12b) to better fulfil a target weight of said portion carrier.

10. A method according to claim 9, characterized in that said food product (3) is cut in a direction transversal to said first and second jaws (12a, 12b).

11. A method according to claim 9 or 10, characterized in that said food product (3) is cut in a direction at an angle (a) to the plane of said belt or table (5), preferably at an angle of about 30-60° and even more preferred 40-50° to the plane of said belt or table.

12. A method according to any of claims 9-11, characterized in that before cutting off said piece (3A) of said food product (3), said cutting device is pivoted around an axis of rotation (C) that is perpendicular to the plane of said belt or table (5).

13. A method according to any of claims 9-12, characterized in that said cutting device (2) comprises one knife blade (22).

14. A method according to any of claims 9-11, characterized in that said cutting device (2) comprises a pair of cutting scissors (22a, 22b) that closes as said first and second jaws (12a, 12b) move into said holding position.

15. A method according to any of claims 9-14, characterized in that said cut off-piece (3A) of said food product (3) is portioned to another portion carrier to fulfil the target weight of that portion carrier.
