Arrangement and method for positioning cartridges for a rock grouting equipment

1. An arrangement ( 10 ) for a rock grouting equipment for positioning at least one cartridge ( 11 ), wherein the arrangement comprises:

at least one storehouse ( 12 ) arranged around a substantially horizontally arranged axis ( 15 ) for holding a plurality of said cartridges ( 11 ), said storehouse ( 12 ) comprising at least one compartment ( 13 ), wherein said at least one compartment is adapted to receive a plurality of said cartridges ( 11 ) placed therein,

at least one catching organ ( 3 , 14 ) extending in a radial direction relative to the horizontally arranged axis ( 15 ), wherein said catching organ ( 3 , 14 ) is arranged to perform a rotating movement around the horizontally arranged axis ( 15 ), and wherein said catching organ ( 3 , 14 ) is arranged and formed such that the catching organ, during said rotating movement, catches at least one of said cartridges between the catching organ ( 3 , 14 ) and an inner surface ( 4 ) of the storehouse body ( 12 ).

2. The arrangement according to claim 1 , wherein said catching organ ( 3 , 14 ) is arranged to place at least one cartridge ( 11 ) in a predetermined position.

3. The arrangement according to claim 2 , further comprising an actuator ( 42 ) arranged to move said at least one cartridge ( 11 ) from said predetermined position to an adjacent to the storehouse ( 12 ) arranged firing arrangement.

4. The arrangement according to claim 3 , wherein the actuator ( 42 ) is arranged to act linear in a direction substantially in parallel with the axis ( 15 ).

5. The arrangement according to claim 3 , wherein said actuator ( 42 ) is arranged to seal the opening of the firing arrangement which is turned towards the storehouse ( 12 ).

6. The arrangement according to claim 3 , further comprising a sensor ( 44 ) arranged to indicate the presence of a cartridge ( 11 ) in said firing arrangement.

7. The arrangement according to claim 1 , further comprising a rotor ( 22 ) provided with at least one in relation to the axis ( 15 ) radially extending rotor blade ( 23 ), wherein said rotor ( 22 ) is arranged to be placed inside the storehouse ( 12 ).

8. The arrangement according to claim 7 , wherein said rotor ( 22 ) comprises several rotor blades ( 23 ), wherein the rotor blades ( 23 ) form delimitations for a plurality of trays ( 13 ) for placing cartridges ( 11 ).

9. The arrangement according to claim 7 , wherein the catching organ ( 3 , 14 ) comprises one or several conveyors ( 14 ) arranged in the periphery part of one or several of the rotor blades ( 23 ) for catching one or more of said cartridges ( 11 ).

10. The arrangement according to claim 9 , wherein the position in radial direction of the one or several conveyors ( 14 ) is adjustable.

11. The arrangement according to claim 1 , wherein said catching organ comprises one or several ridges ( 3 ) extending in parallel with the axis ( 15 ) and arranged in the inner surface area ( 4 ) of the storehouse.

12. The arrangement according to claim 11 , wherein the storehouse ( 12 ) is arranged to rotate around the axis ( 15 ).

13. The arrangement according to claim 1 , wherein the storehouse ( 12 ) is substantially cylindrically shaped.

14. A method in an arrangement ( 10 ) for a rock grouting equipment, wherein said arrangement comprises at least one storehouse ( 12 ) arranged around a substantially horizontally arranged axis ( 15 ) for holding a plurality of cartridges ( 11 ), said storehouse ( 12 ) comprising at least one compartment ( 13 ), wherein said at least one compartment is adapted to receive a plurality of said cartridges ( 11 ) placed therein, and at least one catching organ ( 3 , 14 ) extending in a radial direction relative to the horizontally arranged axis ( 15 ), wherein the method comprises the steps of:

rotating ( 101 ) said catching organ ( 3 , 14 ) around the substantially horizontally arranged axis ( 15 ), and

catching ( 102 ) at least one of said cartridges ( 11 ) during said rotating movement by the at least one catching organs ( 3 , 14 ) between the catching organ and the inner surface ( 4 ) of the storehouse body ( 12 ).

15. The method according to claim 14 , further comprising the step of:

positioning ( 103 ) said at least one caught cartridge ( 11 ) in a predetermined position.

16. The method according to claim 15 , wherein the catching organ ( 3 , 14 ) comprises one or several conveyors ( 14 ) for catching one or more of said cartridges ( 11 ), said method further comprising the step of adjusting the position of said one or several conveyors in a radial direction, wherein the positioning ( 103 ) of said at least one caught cartridge ( 11 ) is tuned by said adjusting of the position of the one or several conveyors in said radial direction.

17. The method according to claim 15 , wherein the arrangement ( 10 ) further comprises an actuator ( 42 ), the method further comprising the step of:

moving ( 104 ) said at least one cartridge ( 11 ) from said predetermined position to an adjacent to the storehouse ( 12 ) arranged firing arrangement.

18. The method according to claim 17 , wherein said moving ( 104 ) occurs linear in a direction substantially in parallel with the axis ( 15 ).

19. The method according to claim 14 , wherein the arrangement ( 10 ) further comprises a sensor, the method further comprising the step of:

indicating ( 105 ) the presence of a cartridge ( 11 ) in said firing arrangement.
