Task: Efficient conveying of sheet metal parts into containers

Sheet metal parts measuring approximately 15x15x10mm are produced in a press at a cycle rate of approximately 150 parts/minute and must be conveyed into containers.

Container dimensions: 470x320x200mm

A buffer solution for 6 containers is to be created.

The container volume should be utilized as efficiently as possible, and pile cones should be avoided as much as possible.

Solution: Conveyor belt combination with movable discharge belt

A straight GL-type machine discharge conveyor with a durable polyester running surface transports the parts into a container provided on a buffer conveyor.

A roof-shaped metal plate is mounted under the outlet of the machine discharge conveyor belt to distribute the parts to the left and right in the container in the direction of conveyance.

The machine discharge conveyor is pneumatically movable in the longitudinal direction and mounted on a base frame in order to move to a second position when the container is half full, thus avoiding pile cones as much as possible.

Filled containers are buffered on a roller conveyor.

Various functions are checked using light barriers on the buffer belt and the subsequent roller conveyor (no empty containers present, containers in filling position, buffer full).

The evaluation is performed using a Siemens S7 controller.

The operating states are indicated by a 3-color signal light.
