Task: Space-saving conveying of medical technology components to assembly machines

Medical-grade plastic parts are produced on two injection molding machines and are to be conveyed to an assembly machine (cleanroom).

The parts are transported lengthwise out of the machines on existing MTF conveyor belts and separated from the sprue using a separating attachment. The parts then pass over a vibrating feeder equipped with ionization units. At this point, the parts must be picked up.

Optionally, both machines should be able to buffer the parts in two boxes each.

There is very little space available and passageways between the machines must be maintained.

Solution: Steep conveyor belt - combination with cleats, covers and light barriers

Each machine has a reversible I-Tech small conveyor belt (items 2 and 5) which directs the parts either onto a pneumatically operated chute (items 3 and 6) or onto two NL special conveyor belts (items 1 and 4).

The conveyor belts have fixed 75° bends to allow for steep upward conveying and the creation of suitable passageways.

To largely prevent the parts from falling back, special cleats are attached to the belts (with an additional welded wedge strip on the cleat tips). Furthermore, fall arresters are installed in the steep sections of the belt.

The conveyor belts are completely covered from above with polycarbonate.

Material transfers are checked for material build-up using light barriers.

Special underframes for mounting the conveyor belts, tippers, and containers Stainless steel pipe system at the conveyor belt outlet (item 6) into the existing feed hopper

Siemens S7 controller including additional modules for on-site evaluation of a higher-level operational data acquisition system.

The upper sections of the inclined belt are attached to the hall ceiling using special brackets.
