Cross-sliding buffer in injection molding machine

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

The empty containers are fed in via a straight conveyor belt type GL along the machine's central axis and positioned at the end of the belt in the middle under the tool and the drop-out switch mounted there.

The number of pieces per container is determined via the machine impulses.

QS parts, start-up parts or reject parts can be diverted to the opposite side of the machine via the switch.

Once the target quantity is reached, the container is pushed sideways from 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 operator side.

At the end of the conveyor belt, a second transverse push takes place onto a roller conveyor, so that the filled containers roll back towards the point where the empty containers are fed in. This ensures the FIFO principle.

The operator can therefore handle the loading and unloading of containers at virtually one location. This saves time, space, and distance.

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 apart from the necessary safety devices (emergency stop button, etc.).
