Linear buffers for extrusion parts

Details MTF Technik Hardy Schürfeld GmbH & Co. KG

Task: Counting and buffering of extrusion parts

Plastic profiles are produced on an extruder. The profiles are cut into 150mm long pieces. Approximately 12 parts are produced per minute.

The products should be taken over by suitable conveyor belts and then counted and buffered in containers

The extruder runs continuously. Container changes must not affect the extruder.

An exact counting result should be achieved

Necessary maintenance access to the production machine should be taken into account

Solution: Linear buffer with foldable roller conveyor and intermediate storage for container changes

Installation of a transfer conveyor belt that takes over the products after the cutting device of the extruder

The belt speed of the transfer belt can be continuously controlled via a frequency converter and adapted to the feed rate of the extruder

Transfer hood at the outlet of the transfer belt with integrated frame light barrier for counting the products

Pneumatic rocker with rear wall for parts routing into the containers or optionally for intermediate storage when changing containers

Feed belt including the necessary sensors for empty containers. Empty containers are provided under the rocker.

Divided gravity roller conveyor with integrated gas spring and pivot mechanism to allow a portion of the roller conveyor to be folded vertically when needed. This allows easy access to necessary maintenance routes.

Siemens S7 for controlling the entire process including interface to the extruder
