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

Medical plastic parts are produced on two injection molding machines and are to be conveyed to an assembly machine (clean room)

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

Optionally, the parts should be buffered in two boxes each on both machines

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

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

One reversible I-Tech small conveyor belt per machine (items 2 and 5), which guides the parts either to a pneumatically operated chute (items 3 and 6) or to two NL special conveyor belts (items 1 and 4)

The conveyor belts have fixed 75° bends to convey as steeply as possible upwards and to create appropriate passages

To prevent the parts from falling back as much as possible, special cleats are mounted on the belts (with additional welded wedge bars on the cleat tips). In addition, fall brakes are installed in the steep belt sections.

The conveyor belts are completely covered from above with polycarbonate

The material transfers are checked for material jamming processes using light barriers

Special base frames for supporting the conveyor belts, rockers, and containers. Stainless steel pipe system at the belt outlet of conveyor belt item 6 into the existing on-site feed hopper.

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

The upper parts of the steep band are attached to the hall ceiling with special brackets
