Product mix

Commercials in A4 format

Configuration

The complete post press system behind a Goss Sunday 3000 consists of a central waste ejection system, four overhead conveying systems with heavy-duty upward and downward conveying towers, four RS 2804 double squeeze rollers, four RS 51 lift stackers as well as two RS 400 palletizing robots with double A4 grippers and two palletizing build zones per robot.

Each shingled stream of the four folder deliveries of the Goss Sunday 3000 runs through a conveying and stacking line before it runs into one of the two palletizing robot cells. From the folder delivery the A4 products are directed to a central waste ejection system where start-up, blanket wash and splice waste is ejected. A flexible divert gate system enables switching the shingled stream of two folder deliveries. So, production with two of four folder deliveries is ensured even if there is a malfunction or maintenance on one of the palletizers.

Good copies are transported into the RS 2804 double squeeze rollers via four space-saving overhead conveying lines, each consisting of two RS 300 heavy-duty upward and downward conveying towers and RS 28 horizontal conveying belts. The double squeeze rollers help to flatten the folds of the products to prevent the build-up of the spines and to ease further processing. The flattened products are directed into the RS 51 lift stacker which turns the shingled stream into perfect and stable bundles without strapping or electrostatic charging. An additional height adjustable waste ejector in the infeed of the RS 51 allows for diverting of waste papers before running into the palletizers.

Finished stacks are ejected and directed via accumulation conveyors to the RS 400 palletizing robot. The palletizer picks up the stacks with its double gripper and puts them gently onto the automatically delivered empty pallet
