Abstract

A strapping apparatus (10) for packages, has a packing table (11) on which the package (13) to be strapped lies. The apparatus has vertically oriented supports (17) which are arranged laterally on the packing table (11), a horizontally oriented pressing plate (18) which is arranged on the vertical supports (11) and which is movable in a vertical direction, and a device, situated on the pressing plate (18), for the arrangement of an edge protection means on the package (13) lying on the packing table (11). The device for the arrangement of the edge protection means can be moved from an initial position remote from the package into an arrangement position close to the package (13). The device includes at least one magazine (19), arranged on the pressing plate (18), for the supply of edge protection means and has a first clearance outline profile which is delimited by the packing table (11), the vertical supports (17), the pressing plate (18) and the at least one magazine (19). The magazine (19) has a normal position which, for the transfer of an edge protection means, corresponds to the initial position of the arrangement device, and the magazine (19) is a part of a first clearance outline profile. The magazine (19) has a deflected position into which it can be moved from the normal position and in which the magazine (19) is part of a second, wider clearance outline profile. A method for strapping packages in a strapping apparatus is also disclosed.

First claim

The invention claimed is:

1. A strapping machine comprising:
a packing table having vertically oriented supports arranged laterally on the packing table;
a horizontally oriented pressing plate arranged on the vertical supports and movable in a vertical direction;
an arrangement device, situated on the pressing plate, for the arrangement of an edge protector on a package positioned on the packing table, wherein the arrangement device is movable horizontally from an initial position remote from the package into an arrangement position closer to the package, and
a magazine arranged on the pressing plate and configured to supply edge protectors;
wherein a first clearance outline profile is delimited by the packing table, the vertical supports, the pressing plate and the magazine,
wherein the magazine has a normal position which, for the transfer of an edge protector, corresponds to the initial position of the arrangement device, and said magazine is a part of the first clearance outline profile, and wherein the magazine is movable relative to the arrangement device from the normal position to a deflected position in which said magazine is part of a second, wider clearance outline profile.

2. The strapping apparatus of claim 1 , wherein the magazine is movable vertically from the normal position into the deflected position.

3. The strapping apparatus of claim 1 , wherein the magazine is movable by way of a spindle drive from the normal position into the deflected position.

4. The strapping apparatus of claim 1 , wherein the magazine is, in its deflected position, arranged behind or in front of one of the vertical supports in relation to a movement path of the package through the strapping apparatus.

5. The strapping apparatus of claim 1 , wherein the magazine, in its deflected position, is arranged vertically above a package contact surface of the pressing plate.

6. A method for strapping packages in a strapping apparatus, the method comprising:
a) arranging the package under a pressing plate;
b) transferring an edge protector from the magazine to an arrangement device that is at an initial position;
c) moving the arrangement device horizontally from the initial position into an arrangement position;
d) moving the magazine relative to the arrangement device from a normal position into a deflected position; and
e) lowering the pressing plate onto the package and holding the edge protector between the pressing plate itself and the package; and
f) applying a strap around the package.

7. A strapping machine comprising:
first and second side supports;
a packing table at least partially between the first and second side supports;
a pressing plate mounted on the first and second side supports and movable relative to the first and second side supports toward and away from the packing table;
first and second magazines supported by the pressing plate and each configured to store multiple edge protectors, the first and second magazines movable between a first configuration in which a first horizontal distance separates the first and second magazines and a second configuration in which a second horizontal distance greater than the first horizontal distance separates the first and second magazines;
a first arrangement device configured to receive an edge protector from the first magazine and later discharge the edge protector, wherein the first arrangement device is horizontally movable between a first initial position and a first arrangement position; and
a second arrangement device configured to receive an edge protector from the second magazine and later discharge the edge protector, wherein the second arrangement device is horizontally movable between a second initial position and a second arrangement position,
wherein the first and second magazines are movable relative to the first and second arrangement devices between the first and second configurations.

8. The strapping machine of claim 7 , further comprising a drive operably connected to the first and second magazines to move the first and second magazines between the first and second configurations.

9. The strapping machine of claim 8 , wherein the drive is operably connected to the first and second magazines to translate the first and second magazines horizontally outward to move the first and second magazines from the first configuration to the second configuration.

10. The strapping machine of claim 8 , wherein the drive comprises a spindle drive.

11. The strapping machine of claim 7 , wherein when the first and second magazines are in the first configuration and the first and second arrangement devices are in their first and second initial positions, the first and second arrangement devices are positioned to receive an edge protector from the first and second magazines, respectively.

12. The strapping machine of claim 11 , wherein the first and second arrangement devices are movable horizontally inwardly from their initial positions to their arrangement positions to discharge the edge protectors onto a load.

13. The strapping machine of claim 7 , wherein the first and second arrangement devices are supported by the pressing plate.

14. The method of claim 6 , further comprising moving the magazine from the normal position into the deflected position after transferring the edge protector to the arrangement device.

15. The method of claim 14 , further comprising moving the magazine horizontally from the normal position into the deflected position.

16. The method of claim 14 , further comprising moving the magazine from the normal position into the deflected position before the pressing plate engages the edge protector.
