Monitoring and rejection system and apparatus
First Claim
1. An adhesive monitoring system for monitoring the application of adhesive to an item, wherein the system includes means for determining the position of the item on a production line, camera means for taking an image of a monitored item, means for triggering the camera means to take an image of the item at one or more set item positions, and processing means for analysing the images produced and for determining the correct application of adhesive from this analysis.

Abstract
A monitoring system checks for correct application of adhesive tracks 6 to e.g. the flap 2 df a cardboard blank 1 on a conveyor system. It includes sensors 14,15 for detecting the position of the blank 1, and a central controller 18 for triggering a camera 16 to take one or more images of the blank 1 at suitable times after the blank 1 is detected, e.g. using the output of an encoder 17. The images may be taken at the expected start, middle and end of the tracks 6, and are analysed by the controller 8 to check for correct application of the tracks 6. The controller 8 and sensors 14,15 can also be used to initially set the dimensions of the blank 1, and the controller 8 can also track a failed blank 1 and reject it later in the conveyor system.

32. An method of monitoring the application of adhesive to an item on a production line, including the steps of determining the position of the item on the production line, triggering a camera to take an image of a monitored item at one or more set item positions, and analysing the images produced to determine whether adhesive has been correctly applied to the item.
- 33. A monitoring system for monitoring items on a production line, the system including camera means for providing one or more images of an item to be monitored, means for determining one or more dimensions of the item to be monitored, and means for controlling the camera means dependent on the determination of these dimensions.
-
38. A system for rejecting an item from a production line, the system including monitoring means for determining whether an item is defective or not, means for rejecting a defective item, and means for monitoring the movement of the defective item and for issuing an instruction to the rejecting means to reject the item when the defective item reaches the rejection means.
-
39. A tab monitoring system for monitoring the removal of a tab from an item, wherein the system includes means for determining the position of the item on a production line, camera means for taking an image of a monitored item, means for triggering the camera means to take an image of the item at one or more set item positions, and processing means for analysing the images produced and for determining the correct removal of a tab from this analysis.
