Abstract

A method for storing cardboard tubes ( 2 ) in a storing unit according to the present invention comprising the following steps: providing a storage unit with an input section for the tubes ( 2 ), a storage section (AC) comprising a plurality of storing planes ( 13 ), an output section for the tubes ( 2 ), transfer means ( 3 ) for transferring the tubes ( 2 ) from the input section to the storage section, and discharge means for conveying the tubes ( 2 ) from the storing section to the output section; providing a plurality of cardboard tubes ( 2 ) in the input section (E) of said storage unit; transferring the tubes ( 2 ) from the input section of the storage unit to the storage section; storing a plurality of tubes ( 2 ) in said storage section (AC); transferring the tubes ( 2 ) from said storage section (AC) to said output section. The step of transferring the tubes ( 2 ) from said input section to said storage section involves more tubes ( 2 ) simultaneously, whereby a plurality of tubes ( 2 ) are transferred from said input section simultaneously on a plurality of storing planes ( 13 ) of the storage section (AC).

First claim

The invention claimed is:

1. A method for storing cardboard tubes in a storage unit, the method comprising the following steps:
providing a storage unit comprising an input section for the cardboard tubes, a storage section comprising a plurality of storing planes on which the cardboard tubes are stored, an output section for the cardboard tubes, a transfer means for transferring the cardboard tubes from the input section to the storage section, and a discharge means for conveying the cardboard tubes from the storage section to the output section;
providing a plurality of the cardboard tubes in the input section of said storage unit;
transferring the cardboard tubes from the input section of the storage unit to the storage section;
storing a plurality of the tubes in said storage section;
transferring the cardboard tubes from said storage section to said output section, wherein transferring the cardboard tubes from said input section to said storage section involves transferring more cardboard tubes simultaneously, whereby a plurality of the cardboard tubes are transferred from said input section simultaneously on a plurality of storing planes of said storage section.

2. A method according to claim 1 , wherein transferring the cardboard tubes from said input section to said storage section is executed with lower speed compared to a previous step in which the cardboard tubes are carried by the input section of the storage unit to a predetermined transferring position, and transferring the cardboard tubes from said input section to said storage section takes place by actuating said transfer means when a speed is lowered.

3. A method according to claim 1 , wherein the cardboard tubes are conveyed sequentially to said transfer means.

4. A storage unit for storing cardboard tubes, the storage unit comprising:
an input section for the cardboard tubes;
a storage section comprising a plurality of storing planes on which the cardboard tubes can be stored;
an output section for the cardboard tubes;
a transfer means for transferring the cardboard tubes from the input section to the storage section;
a discharge means for conveying the cardboard tubes from the storage section to the output section; and
a programmable unit for controlling at least said transfer means, said programmable unit being programmed to automatically perform a method comprising:
providing a plurality of the cardboard tubes in the input section of said storage unit;
transferring the cardboard tubes from the input section of the storage unit to the storage section;
storing a plurality of the tubes in said storage section;
transferring the cardboard tubes from said storage section to said output section, wherein transferring the cardboard tubes from said input section to said storage section involves transferring more cardboard tubes simultaneously, whereby a plurality of the cardboard tubes are transferred from said input section simultaneously on said plurality of storing planes of said storage section.

5. A storage unit according to claim 4 , wherein said transfer means comprises a plurality of levers that can be positioned in an extracted or operative position and respectively in a retracted or inoperative position.

6. A storage unit according to claim 4 , wherein said storage section comprises a plurality of inclined tube storing planes, said inclined planes having a higher input side and a lower output side.

7. A storage unit according to claim 4 , wherein the discharge means comprises a plurality of blade structures mounted to a support structure and an actuator for moving the support structure, wherein each of the blade structures moves from one of a raised position and a lowered position to another one of the raised position and the lowered position upon the actuator moving the support structure in a vertical direction.

8. A storage unit according to claim 4 , wherein the discharge means comprises a plurality of blade structures mounted to a support structure and an actuator for moving the support structure, wherein each of the blade structures moves from one of a raised position and a lowered position to another one of the raised position and the lowered position upon the actuator moving the support structure.

9. A storage unit according to claim 4 , wherein the transfer means comprises a plurality of levers, a lever support structure and an actuator, each of the levers being connected to the lever support structure, each of the levers being simultaneously moved from one of a retracted position to an operative position to another one of the retracted position and the operative position via the actuator.

10. A storage unit according to claim 9 , wherein each of the levers bridges a space between the transfer means and the storage section in the operative position.

11. A method according to claim 1 , wherein the discharge means comprises a plurality of blade structures mounted to a support structure and an actuator for moving the support structure, wherein each of the blade structures moves from one of a raised position and a lowered position to another one of the raised position and the lowered position upon the actuator moving the support structure in a vertical direction.

12. A method according to claim 1 , wherein the discharge means comprises a plurality of blade structures mounted to a support structure and an actuator for moving the support structure, wherein each of the blade structures moves from one of a raised position and a lowered position to another one of the raised position and the lowered position upon the actuator moving the support structure.

13. A method according to claim 1 , wherein the transfer means comprises a plurality of levers, a lever support structure and an actuator, each of the levers being connected to the lever support structure, each of the levers being simultaneously moved from one of a retracted position to an operative position to another one of the retracted position and the operative position via the actuator.

14. A method according to claim 13 , wherein each of the levers bridges a space between the transfer means and the storage section in the operative position.

15. A storage unit for storing cardboard tubes, the storage unit comprising:
an input section for the cardboard tubes;
a storage section comprising a plurality of storing planes on which the cardboard tubes can be stored;
an output section for the cardboard tubes;
a transfer device, the transfer device comprising a plurality of levers connected to a lever support structure and a lever actuator comprising an actuator transmission mechanism, the actuator transmission mechanism being connected to the lever actuator and each of the plurality of levers, wherein each of the levers simultaneously moves from one of an operative position and a retracted position to another one of the operative position and the retracted position via the lever actuator, each of the levers in the operative position bridging a gap between the input section and the storage section, wherein a plurality of the cardboard tubes are transferred from the input section simultaneously on the plurality of storing planes of the storage section when the levers are in the operative position;
