Application device designed to apply a seal to a body element of a vehicle and method
View Patent ↗An application device for applying a seal to a body element of a vehicle, comprising a guiding apparatus to feed continuous material to an outlet apparatus. The application device has a first sensor apparatus to check a predefined end portion of the continuous material for the presence of at least one predefined defect mark. The outlet apparatus has a second sensor apparatus wherein, in the event that the at least one predefined defect mark is present in the predefined end portion, the second sensor apparatus senses an end position of the predefined at least one defect mark along a longitudinal direction of the continuous material. In the event that the at least one predefined defect mark is present in the predefined end portion, the outlet apparatus cuts off a rejection portion of the fed continuous material and feeds said rejection portion to a rejection apparatus.
1 . An application device for applying a seal to a body element of a vehicle, the application device comprising:
a guide to supply continuous material to an outlet of the application device;
a first imaging sensor or device to check a predetermined end portion of the continuous material for the presence of at least one predetermined defect marking; and,
a second imaging sensor or device positioned adjacent the outlet and disposed immediately upstream of a cutting blade of the outlet installation which, in the presence of the at least one predetermined defect marking in the predetermined end portion, detects an end position of the predetermined at least one defect marking along a longitudinal direction of the continuous material, the end position being determined based on a descending flank of a detection signal corresponding to the presence of the defect marking;
wherein in the absence of the predetermined defect marking in the predetermined end portion, a cutting blade associated with the outlet severs the predetermined end portion of the supplied continuous material for application to the body element;
wherein in the presence of the at least one predetermined defect marking in the predetermined end portion, the cutting blade severs an elimination portion of the supplied continuous material for supply to an elimination installation, the elimination portion comprising (i) a defective portion which is delimited by a material start of the supplied continuous material and the end position of the predetermined defect marking along the longitudinal direction of the continuous material and (ii) a safety margin portion extending from the end position of the predetermined defect marking to a cutting location having a predetermined safety margin spacing from the end position.
2 . The application device according to claim 1 , wherein in the presence of at least two predetermined defect markings, the defective portion is delimited by a material start of the supplied continuous material and the end position of a last one of the predetermined defect markings along the longitudinal direction of the continuous material.
3 . The device according to claim 1 , wherein the elimination portion comprises a safety margin portion extending from the end position of the predetermined defect marking to a cutting location having a predetermined safety margin spacing from the end position of the predetermined defect marking.
4 . The device according to claim 3 , wherein the predetermined safety margin spacing has a length of 120 mm to 200 mm.
5 . The device according to claim 3 , wherein the predetermined safety margin spacing has a length of 130 mm to 190 mm.
6 . The device according to claim 3 , wherein the predetermined safety margin spacing has a length of 140 mm to 180 mm.
7 . The device according to claim 3 , wherein the predetermined safety margin spacing has a length of 150 mm to 170 mm.
8 . A method for operating an application device for applying a seal to a body element of a vehicle, the method comprising:
supplying continuous material to an outlet of the application device by way of a guide;
checking a predetermined end portion of the continuous material for the presence of at least one predetermined defect marking by a first imaging sensor or device;
severing the predetermined end portion from the supplied continuous material and applying it to the body element, in the absence of the predetermined defect marking;
detecting an end position of the defect marking along a longitudinal direction of the continuous material, in the presence of the at least one predetermined defect marking in the predetermined end portion, by a second imaging sensor or device positioned adjacent the outlet and disposed immediately upstream of a cutting blade of the outlet installation, wherein the end position is determined based on a descending flank of a detection signal corresponding to the presence of the defect marking; and,
severing an elimination portion of the supplied continuous material, in the presence of the at least one predetermined defect marking, and supplying the elimination portion to an elimination location;
wherein the elimination portion comprises (i) a defective portion delimited by a material start of the supplied continuous material and the end position of the predetermined defect marking along the longitudinal direction of the continuous material and (ii) a safety margin portion extending from the end position of the predetermined defect marking to a cutting location having a predetermined safety margin spacing from the end position.
9 . The method according to claim 8 , wherein severing is performed by a cutting blade.
10 . The method according to claim 8 , wherein in the presence of at least two predetermined defect markings, the defective portion is delimited by a material start of the supplied continuous material and the end position of a last one of the predetermined defect markings along the longitudinal direction of the continuous material.
11 . The method according to claim 8 , wherein the elimination portion comprises a safety margin portion extending from the end position of the predetermined defect marking to a cutting location having a predetermined safety margin spacing from the end position of the predetermined defect marking.
12 . The method according to claim 11 , wherein the predetermined safety margin spacing has a length of 120 mm to 200 mm.
13 . The method according to claim 11 , wherein the predetermined safety margin spacing has a length of 130 mm to 190 mm.
14 . The method according to claim 11 , wherein the predetermined safety margin spacing has a length of 140 mm to 180 mm.
15 . The method according to claim 11 , wherein the predetermined safety margin spacing has a length of 150 mm to 170 mm.
