Linear buffers for extruded parts

Details MTF Technik Hardy Schürfeld GmbH & Co. KG

Task: Counting and buffering of extruded parts

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

The products should be transferred to suitable conveyor belts and then counted and buffered in containers.

The extruder runs continuously. Changing the container must not affect the extruder.

The goal is to achieve an exact counting result.

Necessary maintenance access points on 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 adjusted to the feed rate of the extruder.

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

Pneumatic rocker with back panel for feeding parts into containers or optionally for temporary storage during container changes.

Conveyor belt including necessary sensors for empty containers. Empty containers are positioned under the rocker.

Split gravity roller conveyor with integrated gas spring and swivel mechanism to allow a section of the conveyor to be folded vertically upwards when needed. This provides easy access for necessary maintenance.

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