Tensioning rail applied by injection molding
View Patent ↗A device for checking ( 1 ) whether a first object ( 2 ) with an adhesive ( 4 ) affixed thereto is glued onto a second object ( 3 ) by means of the adhesive ( 4 ), including an excitation unit ( 5 ) for exciting luminescence of the adhesive ( 4 ) and a detection unit ( 6 ) for the selective detection of luminescence light of the adhesive ( 4 ). Also provided is a device for gluing a first object ( 2 ) with an adhesive ( 4 ) affixed thereto onto a second object ( 3 ) and having an applicator ( 8 ) for gluing on the first object ( 2 ) and a device for checking ( 1 ) Also provided is a method for checking whether a first object ( 2 ) with an adhesive ( 4 ) affixed thereto is glued onto a second object ( 3 ) by means of the adhesive, including excitation of the adhesive ( 4 ) to luminescence and the selective detection of the luminescence light generated in the adhesive ( 4 ). There is also a method for gluing a first object ( 2 ) onto a second object ( 3 ) where the first object is glued onto a second object by means of an applicator ( 8 ) and where a method for checking is performed.
1. A device for checking for the presence of an adhesive on a drink package to confirm whether a straw bag is affixed to the drink package at a predetermined position on the drink package, the device comprising an illumination unit constructed and positioned to illuminate the adhesive at the predetermined position and a detection unit constructed and positioned to detect the presence or absence of luminescence light that illuminates the adhesive at the predetermined position.
2. A device according to claim 1 , wherein the illumination unit is constructed and arranged to excite the adhesive.
3. A device according to claim 1 , wherein the detection unit is constructed and arranged to detect light in the visible spectral region.
4. A device according to claim 1 , wherein the detection unit generates a detection signal, the device further comprising an evaluation unit constructed and arranged to evaluate the detection signal of the detection unit.
5. A device according to claim 2 , wherein the illumination unit is constructed and arranged to illuminate the adhesive with UV light.
6. A device according to claim 3 , wherein the detection unit is constructed and arranged to detect luminescence light in the blue spectral region of the visible spectral region.
7. A device according to claim 1 , wherein the straw-bag is at least partly transparent.
8. A device according to claim 1 , wherein the drink package is a foil-bag.
9. A method for checking for the presence of an adhesive on a drink package to confirm whether a straw bag is affixed to the drink package at a predetermined position, the method comprising illuminating the adhesive at the predetermined position, and selectively detecting the presence of absence of a luminescence light illuminating the adhesive at the predetermined position.
10. A method according to claim 9 , wherein the illuminating the adhesive comprises exciting the adhesive with a light.
11. A method according to claim 9 , wherein the detection occurs in the visible spectral region.
12. A device according to claim 9 , wherein the adhesive contains a luminescence dye.
13. A method according to claim 10 , wherein the light is UV light.
14. A method according to claim 11 , wherein the detection occurs in the blue spectral region.
15. A method according to claim 8 , wherein the drink package is a foil-bag.
16. A device for affixing and confirming that a straw-bag having an adhesive is affixed to is affixed to a drink package at a predetermined position, the device comprising an applicator for affixing the straw-bag onto the drink package at the predetermined position, an illumination unit constructed and positioned to illuminate the adhesive at the predetermined position, and a detection unit for the selective detection of a presence or absence of luminescence light illuminating the adhesive at the predetermined position.
17. A device according to claim 16 , further comprising one of a rejection unit, constructed and positioned to reject a drink package without a straw bag affixed thereto, and an additional applicator, constructed and positioned to affix another straw-bag to the drink package, the rejection unit and the additional applicator being at or downstream from the device.
18. A method for affixing and confirming that a straw-bag is affixed onto a drink package at a predetermined position, the method comprising affixing a straw-bag onto a drink package at the predetermined position by an adhesive; illuminating the adhesive at the predetermined position until the adhesive generates a luminescence light; and selectively detecting the luminescence light generated in the adhesive at the predetermined position.
19. A method according to claim 18 , further comprising rejecting the drink package and affixing another straw-bag to the drink package.
