Design and implementation of a dynamic weighing system

Project objective

Design and implementation of a dynamic weighing system, with an option of rejecting cargo, the weight of which does not fit within the specified value.

Task description by the customer - "Alkogolnaya Sibirskaya Gruppa"

Разработать и внедрить на предприятиях “Омсквинпром” и “Рузский

Developing and implementing a dynamic weighing system at “Omskvinprom” and “Ruzsky Kupazhniy zavod” factories. The system must operate according to the following algorithm:

  1. The goods are delivered to the weighing conveyor;
  2. Weighing takes place during which there should be one unit on the weighing conveyor;
  3. If the weight is within the specified value, then it passes further, and a signal is sent from the controller that the weight is normal;
  4. When the weight is not within the set value, the load passes further, and a signal is sent from the controller that the weight is not normal (overweight/underweight);
  5. When the goods pass the receiving (roller) conveyor, the rejector is triggered;
  6. The load is rejected onto a non-driven roller conveyor;
  7. If the non-driven roller conveyor is full, a light is triggered and the line stops.
Solution key features
  • Controlling the speed of conveyor motors, feeding and weighing set automatically or manually;
  • Ensuring a run-up between product samples for a more accurate weighing;
  • Weighting the product;
  • Controlling emergency situations;
  • Rejecting products that have not passed weight control.
Project implementation stages
  1. Preparing technical specifications;
  2. Determining the system’s main components;
  3. System production;
  4. Delivery to the place of installation;
  5. Installation, testing. Putting the system into operation. Putting the system into operation. Commissioning works are being carried out to set up the interaction of electrical equipment systems in various modes.

These works include:

  • ensuring intercouplong, adjusting and setting the characteristics and parameters of individual devices and functional groups in order to ensure the specified operating modes;
  • testing equipment at idle speed and under load in all operating modes to prepare for operation.
Software and hardware system
  • Simatic S7-1200 controller;
  • In-house SCADA system;
  • In-house weighing system;
  • Operator panel.
