Abstract

The present disclosure provides a strapping apparatus for strapping articles to be packaged with a strapping band. The strapping apparatus includes a band detection device configured to indicate that the band is in a non-positionally correct and/or a positionally correct position, depending on the embodiment.

First claim

The invention claimed is:

1. A strapping tool comprising:
a tensioning device comprising a tensioning element rotatable to tension a loop of strapping band;
a connecting device actuatable to connect two regions of the loop of strapping band together; and
a band-detection device comprising a contact portion and a signaling portion, wherein the band-detection device is movable between a rest position and a signaling position, wherein the band-detection device is positioned so positioning the strapping band in a non-positionally-correct position causes the strapping band to contact the contact portion, which causes the band-detection device to move to the signaling position and cause the signaling portion of the band-detection device to signal that the strapping band is in the non-positionally-correct position.

2. The strapping tool of claim 1 , wherein the band-detection device is pivotable between the rest position and the signaling position.

3. The strapping tool of claim 2 , wherein the contact portion partially defines a band channel that defines a positionally-correct position of the strapping band.

4. The strapping tool of claim 3 , wherein the band channel extends longitudinally through the tensioning device and the connecting device, and wherein the contact portion is positioned to define a lateral extent of the band channel.

5. The strapping tool of claim 1 , wherein the signaling portion of the band-detection device comprises a marking that is hidden when the band-detection device is in the rest position and that is visible when the band-detection device is in the signaling position.

6. The strapping tool of claim 5 , further comprising a housing at least partially enclosing the tensioning device, the connecting device, and the band-detection device, wherein the housing defines an opening sized and positioned so the marking of the signaling portion of the band-detection device is visible through the opening when the band-detection device is in the signaling position and not visible through the opening when the band-detection device is in the rest position.

7. The strapping tool of claim 1 , further comprising a housing at least partially enclosing the tensioning device, the connecting device, and the band-detection device, wherein the tensioning device is positioned at a front end of the housing, the connecting device is positioned rearward of the tensioning device, and the contact portion of the band-detection device is positioned rearward of the connecting device.

8. The strapping tool of claim 7 , further comprising a base plate supporting the tensioning device and the connecting device, wherein the contact portion of the band-detection device engages the base plate when the band- detection device is in the rest position.

9. The strapping tool of claim 1 , wherein the signaling portion of the band-detection device is laterally offset from the contact portion of the band-detection device.

10. The strapping tool of claim 9 , wherein the contact and signaling portions of the band-detection device extend in different directions.

11. The strapping tool of claim 1 , further comprising a base plate, wherein the band-detection device further comprises a lever portion pivotably mounted to the base plate so the band-detection device is pivotable between the rest position and the signaling position.

12. The strapping tool of claim 11 , wherein the contact portion of the band-detection device extends toward the base plate and the signaling portion of the band-detection device extends away from the base plate.

13. The strapping tool of claim 12 , wherein the contact portion of the band-detection device engages the base plate when the band-detection device is in the rest position.

14. The strapping tool of claim 11 , further comprising a housing at least partially enclosing the tensioning device, the connecting device, and the band-detection device, wherein the tensioning device is positioned at a front end of the housing, the connecting device is positioned rearward of the tensioning device, and the contact portion of the band-detection device is positioned rearward of the connecting device.

15. The strapping tool of claim 14 , wherein the contact portion partially defines a band channel that defines a positionally-correct position of the strapping band.

16. The strapping tool of claim 15 , wherein the band channel extends longitudinally through the tensioning device and the connecting device, and wherein the contact portion is positioned to define a lateral extent of the band channel.

17. The strapping tool of claim 11 , wherein the signaling portion of the band-detection device comprises a marking that is hidden when the band-detection device is in the rest position and that is visible when the band-detection device is in the signaling position.

18. The strapping tool of claim 17 , further comprising a housing at least partially enclosing the tensioning device, the connecting device, and the band-detection device, wherein the housing defines an opening sized and positioned so the marking of the signaling portion of the band-detection device is visible through the opening when the band-detection device is in the signaling position and not visible through the opening when the band-detection device is in the rest position.

19. The strapping tool of claim 11 , wherein the base plate comprises a carrier, wherein the lever portion of the band-detection device is pivotably mounted to the carrier.

20. The strapping tool of claim 11 , wherein the band-detection device further comprises a connecting portion transverse to the lever portion and extending between the contact portion and the signaling portion, wherein the band-detection device is pivotably mounted to the base plate at a first end of the lever portion, and wherein the contact portion is connected to a second free end of the lever portion that is opposite the first end of the lever portion.
