Gripping device

1. A gripping device comprising:

two grippers disposed in opposed relationship with one another and adapted to be moved towards one another, each of said grippers including a holder and a gripping jaw attached thereto, wherein for each gripper, the holder has a C-shaped portion that exhibits a two-directional elasticity to allow a horizontal as well as a vertical movement of the gripping jaw;

wherein each of said holders of said grippers include a first end and a second end, the first end of each of said holders operably connected to one of said gripping jaws and the second end of at least one of said holders being coupled to a linear actuator to move said gripper in at least a substantially horizontal direction.

2. A gripping device according to claim 1 wherein each holder is implemented as an integral component.

3. A gripping device according to claim 1 wherein each holder is made of polyoxymethylene.

4. A gripping device according to claim 1 wherein each holder is provided with a stop for limiting the horizontal movement and/or the vertical movement.

5. A gripping device according to claim 1 wherein each holder has a spring constant, and the spring constants are the same.

6. A gripping device according to claim 1 wherein, for each gripper, the gripping jaw is adapted to be adjusted relative to the holder.

7. A gripping device according to claim 1 wherein each gripping jaw has a substantially perpendicularly oriented contact surface, and the gripping jaws act relative to one another for picking up a product by means of frictional engagement.

8. A gripping device according to claim 1 wherein the linear actuator is a pneumatic cylinder for moving the grippers away from and towards one another.

9. A gripping device according to claim 8 wherein displacement speed and/or power of the pneumatic cylinder can be adjusted.

10. A gripping device according to claim 1 further comprising a handling unit on which the grippers are supported.

11. A gripping device according to claim 10 wherein the handling unit is a two-, three- or four-axis robot.

12. A gripping device according to claim 1 wherein said C-shaped portion includes a first end section and a second end section wherein said first and second end sections are substantially parallel prior to any horizontal or vertical movement of said gripping jaw.

13. A gripping device comprising:

a support body; and

two grippers supported by the support body and disposed in opposed relationship, wherein at least one of the grippers is adapted to be moved toward another of the grippers, and each of the grippers includes a holder and a gripping jaw attached to the holder, and wherein for each gripper, the holder has a C-shaped portion that provides a two-directional elasticity to allow movement of the gripping jaw in two perpendicular directions relative to the support body;

wherein each of said holders of said grippers include a first end and a second end, the first end of each of said holders operably connected to one of said gripping jaws and the second end of at least one of said holders being coupled to a linear actuator to move said gripper in at least a substantially horizontal direction.

14. A gripping device according to claim 13 wherein each holder is provided with at least one stop for limiting movement of the respective gripper jaw in at least one of the two directions.

15. A gripping device according to claim 13 wherein, for each gripper, the gripping jaw is adapted to be adjusted relative to the holder.

16. A gripping device according to claim 13 wherein each gripping jaw has a substantially planar contact surface and an angled portion extending from a lower end of the contact surface, and the gripping jaws act relative to one another for picking up a product.

17. A gripping device according to claim 13 further comprising a handling unit on which the support body is supported.

18. A gripping device according to claim 17 wherein the handling unit is a two-, three- or four-axis robot.
