Shifting belt buffer with small conveyor belt

Details MTF Technik Hardy Schürfeld GmbH & Co. KG

Task: Buffering of metal rings using a conveyor system

Up to 150 metal rings per minute are produced in a special mechanical press.

The manufactured parts are blown out of the tool and "fly" out of the system.

The parts must be picked up by the conveyor system and slowed down.

The ejection of parts must be controlled at the interface to the buffer system (tool safety).

The produced parts are to be fed into different containers.

QS parts must be removed separately from each container.

The system must be able to accommodate different types and sizes of containers.

A control system is intended to monitor the system status and document the distribution of parts to the various containers.

Solution: Small conveyor belt with discharge duct and diverter valves

Stable welded frame with insertion option for four container holders

Docked closed stainless steel discharge duct as interface to the press with integrated small conveyor belt

Flexible flaps are installed in the discharge duct to slow down the parts.

A light curtain is integrated at the transition to the press for tool safety (presence control of the ejected parts).

Integrated access flaps for maintenance and cleaning purposes on the discharge duct

Linearly movable, reversible small conveyor belt type IL in the frame with pneumatic diverters attached on both sides

The pneumatic linear drive allows access to various dispensing points in the respective containers, in order to largely avoid cone formation.

Quality control parts are dispensed at a defined position in each container.

Buffer frame fully covered with polycarbonate. On the operator side, two hinged covers with gas spring support for cleaning or maintenance purposes.

Entry aids on the buffer frame for simplified positioning of the container wagons

Presence monitoring of the containers using light barriers

Each container position is equipped with an operator terminal that displays information such as the item number, target quantity, actual quantity, and other system statuses. The operator must acknowledge the container change on the terminal.
