Abstract

A strapping apparatus ( 10 ) for packages ( 16 ) has a frame-like strapping channel which is composed of an upper and a lower channel section ( 19 ) which are connected by way of a first and a second vertical section ( 18, 20 ). A first diverting device connects ( 21 ) the first vertical section to the lower channel section, and a second diverting device ( 22 ) connects the lower channel section to the second vertical section. A bayonet ( 24 ) which can be inserted along a movement path alternative to the lower channel section ( 19 ) into the strapping channel, in which the insertion movement is directed from the first to the second diverting device. The first diverting device is mounted on a pivot axle ( 27 ) by means of which the first diverting device can be moved from a normal position, which connects the first vertical section and the lower channel section, into a deflected position, in which the connection is eliminated. A guide element is arranged on that end of the bayonet which is averted from the bayonet tip, which guide element connects the first vertical section to a channel section formed by the bayonet.

First claim

The invention claimed is:

1. A strapping apparatus comprising:
a packing table;
spaced-apart upper and lower channel sections connected to each other by spaced-apart first and second side channel sections, wherein the upper and lower channel sections and the first and second side channel sections form a strapping channel encircling the packing table;
a first diverting device which connects the first side channel section to the lower channel section, wherein the first diverting device comprises a base part and a back part transverse to the base part, wherein the first diverting device is mounted on a pivot axle and is pivotable between a normal position and a deflected position, wherein when the first diverting device is in the normal position the back part is generally aligned with the first side channel section and the base part is generally aligned with the lower channel section so the first diverting device connects the first side channel section and the lower channel section, wherein when the first diverting device is in the deflected position the back part is not aligned with the first side channel section and the base part is not aligned with the lower channel section so the first diverting device does not connect the first side channel section and the lower channel section;
a second diverting device which connects the lower channel section to the second side channel section;
a bayonet comprising a bayonet channel section, wherein the bayonet can be moved along a movement path directed from the first diverting device to the second diverting device such that, after the bayonet has reached the end of the movement path, the bayonet channel section, the upper channel section, and part of the first and second side channel sections form an alternative strapping channel,
wherein the pivot axle is positioned underneath the bayonet such that movement of the bayonet along the movement path causes the bayonet to force the first diverting device to pivot so the back part pivots toward the packing table and the base part pivots away from the packing table as the first diverting device pivots from the normal position to the deflected position; and

a guide element arranged on an end of the bayonet which is spaced-apart from a bayonet tip, which guide element connects the first side channel section to the bayonet channel section after the bayonet has reached the end of the movement path.

2. The strapping apparatus of claim 1 , wherein the pivot axle is oriented parallel to the packing table and transverse to the movement path of the bayonet.

3. The strapping apparatus of claim 1 , wherein the first diverting device is equipped with a spring configured to return the first diverting device from its deflected position into its normal position.

4. The strapping apparatus of claim 1 , wherein the bayonet tip is equipped with a lug which forms part of a base of the bayonet channel section, wherein the base is curved in an upward direction pointing away from the packing table.

5. The strapping apparatus of claim 4 , wherein a guide tongue is arranged above the lug so as to form a gap.

6. The strapping apparatus of claim 4 , wherein the second diverting device is arranged in the movement path of the bayonet and has a receptacle for the bayonet tip.

7. The strapping apparatus of claim 4 , wherein, after the bayonet has reached the end of the movement path, the lug of the bayonet tip forms a transition between the bayonet channel section and a channel section of the second diverting device.

8. A strapping machine comprising:
first and second side components defining respective first and second side strapping channel sections;
a lower component at least partially between the first and second side components and defining a lower strapping channel section;
a first diverting device pivotable between: (1) a normal position in which the first diverting device connects the first side strapping channel section and the lower strapping channel section; and (2) a deflected position in which the first diverting device does not connect the first side strapping channel section and the lower strapping channel section; and
a bayonet that defines a bayonet strapping channel section and that is movable relative to the first and second side components, the lower component, and the first diverting device between a retracted position and an inserted position,
wherein the first diverting device is pivotable about a pivot axis of a pivot axle such that movement of the bayonet from the retracted position to the inserted position causes the bayonet to contact the first diverting device to force the first diverting device to pivot from the normal position into the deflected position, wherein the pivot axis is positioned underneath the bayonet, is transverse to the bayonet strapping channel section, and is transverse to the first and second side strapping channel sections,
wherein when the bayonet is in the inserted position, the bayonet strapping channel section is connected to the first and second side strapping channel sections.

9. The strapping machine of claim 8 , further comprising an upper component supported by the first and second side components and defining an upper strapping channel section that connects the first and second side strapping channel sections.

10. The strapping machine of claim 9 , wherein the upper component comprises a press plate movable relative to the first and second side components and the lower component between an upper position and a lower position.

11. The strapping machine of claim 8 , further comprising a second diverting device that, when the bayonet is in the retracted position, connects the lower strapping channel section and the second side strapping channel section.

12. The strapping machine of claim 11 , wherein when the bayonet is in the inserted position, the second diverting device connects the bayonet strapping channel section and the second side strapping channel section.

13. The strapping machine of claim 12 , wherein the second diverting device defines a receptacle configured to receive a front end of the bayonet.

14. The strapping machine of claim 13 , wherein the front end of the bayonet comprises an upwardly curved lug.

15. The strapping machine of claim 8 , wherein the first diverting device comprises a roller, wherein the roller is positioned to engage the underside of the bayonet when the first diverting device is in the deflected position and the bayonet is in the inserted position.

16. The strapping machine of claim 15 , further comprising a biasing element that biases the first diverting device to the normal position.

17. The strapping machine of claim 8 , wherein the first and second side components are vertical supports, wherein the lower component is horizontal.

18. The strapping machine of claim 8 , wherein the first diverting device comprises a base part and a back part oriented transverse to one another,
wherein when the first diverting device is in the normal position, the back part is generally aligned with the first side strapping channel section and the base part is generally aligned with the lower strapping channel section,
wherein when the bayonet is in its inserted position and the first diverting device is in its deflected position, the base part and the back part of the first diverting device are both entirely beneath the bayonet.

19. A strapping machine comprising:
first and second side components defining respective first and second side strapping channel sections;
a lower component at least partial
