In all areas, components were sought that would allow for lubrication-free operation with simple maintenance, minimal noise levels and low costs. Our linear and rotary plain bearings are used for various tasks at the four stations:
1. Conveyor bridge:
The miniature conveyor/discharge bridge with a roller surface of 65mm x 120mm was designed with a series of iglidur G plain bearings (GSM-0810-22), which run freely over fixed smooth stainless-steel rods with a diameter of 8mm. This reduced the roller conveyor's friction virtually to zero while making it very simple and free from both maintenance and corrosion. It could furthermore be mounted in the tightest of spaces.
2. Pusher:
The pusher is constructed using a drylin W profile guide in combination with a pair of the corresponding drylin W housing pillow blocks and a pair of adjustable pillow blocks. When moving forwards, this arrangement lowers the push rod so that it pushes a range of products sideways. During the return stroke, this arrangement lifts the rod above the products so that they can enter the pushing area even if the push rod still has to be retracted. This arrangement requires only one low-friction cylinder to perform both horizontal and vertical movements. This allows for a very fast and reliable mechanism.
3. Carton feed:
For the carton indexer, which ensures the feed in the system, a combination of drylin W profile guide, drylin W pillow block and an adjustable bearing variant was used in a similar way to achieve reliable operation.
4. Carton lifting:
The handling system for lifting the cardboard boxed was realised with a vertical guide system with two drylin W rails and only four drylin W pillow blocks, which are arranged in such a way that they fully accommodate the protruding load. This arrangement is light, with virtually no friction, quiet and cost-effective.
