During the production of offset pressure plates, the plates need to be assembled and packaged. In the process, large plates are cut through lengthwise to produce two small plates. These plates then have to be guided to a packaging machine. A conveyor system that sets the two plates at a specific distance and aligns them parallel to each other is now required.
To spread out the two plates, a belt conveyor combination consisting of two parallel belt conveyors with a vacuum function was developed in collaboration with the customer. The vacuum is designed to fix the plates on the conveyor while still allowing for relative movement. The conveyors can be set at an angle to each other. This allows the plates to be spaced correctly over the course of the conveying path.
To then align the plates in parallel again, another belt conveyor combination consisting of three belt conveyors with a vacuum function was designed. Each conveyor line has its own drive. The middle conveyor line has a constant speed. The speed of the two outer conveyor lines can be controlled independently of each other through their own drives. A camera detects the tilted position of the plates. The speed of the relevant conveyor line is then adjusted accordingly to turn the plate by the required number of degrees. Once the tilted position has been accurately corrected, the conveyor speed is set to match the middle line again and the plate is supplied to the packaging system with the correct alignment. A low-friction fleece belt was used to enable the relative movement of the plates.
