Abstract

A device arranges an edge protector on a package. The device includes a drive wheel for moving the device along a guiding rail from a point of departure to the package and from the package to the point of departure. A motor is carried by the device and drives the drive wheel. A clamp mount includes a movable clamping jaw and a counter bearing for taking up the edge protector in an open position of the clamping jaw and to hold it in a closed position of the clamping jaw. The motor drives the drive wheel and acts on a power transmission assembly to induce opening and closing of the clamping jaw. A device for strapping packages having the edge protector applicator includes a frame carrying a press plate above a vertically movable packing table. The press plate has running rails on which the edge protector applicator is movably mounted. The applicator device is mounted below the press plate.

First claim

The invention claimed is:

1. A device for arranging an edge protector on a package, the device comprising:
a chassis;
at least one drive wheel mounted to the chassis and configured to rotate relative to the chassis and move the chassis along a rail from a point of departure to the package and from the package to the point of departure;
a motor operably connected to the at least one drive wheel and configured to rotate the at least one drive wheel;
a counter bearing mounted to the chassis; and
a clamping jaw mounted to the chassis, wherein the motor is operably connected to the clamping jaw via at least one power transmission device and is configured to move the clamping jaw relative to the counter bearing between an open position and a closed position.

2. The device of claim 1 , wherein the at least one power transmission device is configured to move the clamping jaw to the closed position when the motor causes the at least one drive wheel to rotate to move the chassis along the rail toward the package and is configured to move the clamping jaw to the open position when the motor causes the at least one drive wheel to rotate to move the chassis along the rail back toward the point of departure.

3. The device of claim 1 , wherein the clamping jaw is part of a pivotable lever that is pivotable around a swivel axis.

4. The device of claim 3 , further comprising a first end stop positioned to stop the lever from moving when the clamping jaw reaches the open position.

5. The device of claim 4 , wherein the at least one power transmission device includes a first gear positioned on an axis of the at least one drive wheel via a slipping clutch configured to discard overload and hold a defined torque when the clamping jaw reaches the open position or the closed position.

6. The device of claim 4 , further comprising a second end stop positioned to stop the lever from moving when the clamping jaw reaches the closed position.

7. The device of claim 3 , wherein the at least one power transmission device includes a first gear positioned on an axis of the at least one drive wheel.

8. The device of claim 7 , wherein the at least one power transmission device further comprises a second gear rotatable around the swivel axis, wherein the first drive gear drivingly engages the second gear.

9. The device of claim 7 , wherein the first gear is positioned on the axis of the at least one drive wheel via a slipping clutch configured to discard overload and hold a defined torque when the clamping jaw reaches the open position or the closed position.

10. The device of claim 1 , wherein the chassis is part of the motor.

11. A device for strapping packages, the device comprising:
a frame;
a press plate movably mounted to the frame and including a rail;
a packing table positioned below the press plate and at least partially within the frame; and
a device for arranging an edge protector on a package positioned on the packing table, the device for arranging the edge protector comprising:
a chassis;
a drive wheel mounted to the chassis and bearing on the rail of the press plate, wherein the drive wheel is configured to rotate relative to the chassis and move the chassis along the rail from a point of departure to the package and from the package to the point of departure;
a motor operably connected to the drive wheel and configured to rotate the drive wheel;
a counter bearing mounted to the chassis; and
a clamping jaw mounted to the chassis, wherein the motor is operably connected to the clamping jaw via at least one power transmission device and is configured to move the clamping jaw relative to the counter bearing between an open position and a closed position.

12. The device of claim 11 , further including a lifting device configured to lift the device for arranging the edge protector on the package such that the drive wheel does not contact the rail.

13. The device of claim 12 , wherein the lifting device comprises an electromagnet configured to be charged with an electric current to induce a magnetic force that acts on a metallic part of the device for arranging the edge protector on the package to lift the device for arranging the edge protector on the package such that the drive wheel does not contact the rail.

14. The device of claim 1 , wherein the lifting device comprises a lifting arm configured to engage a lifting element of the device for arranging the edge protector on the package to lift the device for arranging the edge protector on the package such that the drive wheel does not contact the rail.
