The automatic line and coil packing

The confectionery company Wilh.-Schmitz Scholl GmbH makes and processes a broad selection of chocolates for his clientele. Until finally just lately, a one piping program was used which inevitably required extended down-times for the alter-above to a various chocolate mass, since comprehensive rinsing of all pipelines is vital. In get to reduce these down-instances to a least, a 3-7 days halt in manufacturing was utilised to install a new pipeline program which allows separation of the various colors of chocolate. The update concerned integration of a new method advice program and the addition of new measuring and handle tools.

The up grade involved integration of a new procedure assistance program and the addition of new measuring and management gear. DTA DELTA TECHNIK projected and launched the automatization of the new principle of mass. Even though nonetheless in the proposal phase, DTA DELTA TECHNIK experienced already commenced mapping out a idea which produced it feasible to total the conversion inside 3 weeks of a plant shut-down.

The installation was divided into 5 locations, each and every with 1 Simatic S7-300 manage program. The grouping was primarily based on hierarchy as properly as on generation traces. Benefits of decentralization (preserving on wiring expenses, smaller sized handle cupboards, shorter assembly routes) had been mixed with the advantages of distributed intelligence (autarkical execution of method cycles).

The Siemens operator management- and monitoring program Simatic WinCC was installed in a centrally positioned production workplace.

Visualization was also carried out on 5 ranges but it was primarily based on the circulation route of the mass, not on the control techniques. All visualization photographs have the same body with a defined keypad location, although a variable keypad part is linked with each impression. Changing products parameters requires password authorization.

Profibus-tP engineering was utilised in the implementation of all phases of automation, providing for elevated communication demands in parallel with really quick response moments (visualization, S7-300 automation gear, frequency converters, and so on.).

The installation is binary actuators and sensors are activated via the AS- interface networking program. Pneumatic user modules are employed to activate the around two hundred pneumatic flap gates. The consumer modules have two digital entry ports to connect the position opinions messages, and two pneumatic exits. The two pneumatic exits are understood through two pilot-operated three/two-way seated valves with shared strain source and shared exhaust air. Both pneumatic exits of the module can be operated by hand employing different slide bars.

The complete concept is rounded off by software of Endress + Haumans industrial measurement technology. 35 fill-degree measurements, 38 temperature measurements and seven Coriolis mass-throughput measuring units, (Promass) are recorded through Profibus-PA. All measuring-technologies discipline units can be parameterized from a central position in the Commuwin II running system.

The new principle of mass was productively applied at the restart of on-plan production of the most-utilized mixes, followed by the remaining item mixes inside of the 1st two manufacturing weeks.
