Cross-sliding buffer in injection molding machine

A combination of two straight conveyor belts, two cross-shifting units and a roller conveyor for the filled containers

The empty containers are fed via a straight conveyor belt type GL along the machine center axis and are placed at the end of the belt centrally under the tool and the drop-out switch mounted there.

The number of pieces per container is determined via the machine pulses

QA parts, start-up parts or reject parts can be ejected via the switch to the opposite side of the machine

Once the target quantity has been reached, the container is pushed across the belt onto a second belt conveyor by means of a pneumatic cross-shifting unit

The second conveyor belt transports the containers in the machine bed to the operating side

At the end of the belt, a second transverse shifting process takes place onto a roller conveyor, so that the filled containers roll back towards the empty container drop-off point. This ensures the FIFO principle.

The operator can thus load and unload the containers virtually in one position. This saves time, space, and travel.

The U-shaped design, including the use of the machine bed for empty containers and the machine overhang on the operator side for filled containers, allows for almost complete integration into the machine's footprint. There are virtually no protruding components other than the necessary safety devices (emergency stop buttons, etc.).
