Design and implementation of a system for weight and size determination

Project objective

Design and implementation of a system for goods’ weight and size determination, with the option to automatically scan barcodes on the parcels’ top or side. Development and assembly of control cabinets.

Task description by the customer - "Major Express"

Developing and implementing a conveyor control system at the Major Express warehouse, with the option to automatically determine the dimensions of goods and their weight. Providing automatic barcode reading. Installing an operator’s workstation with a monitor in the system’s vicinity.

Solution key features
  • The operator puts the parcel onto the conveyor;
  • The parcel passes through the measuring system, its dimensions and weight are determined, the barcode is automatically read, all data is entered into the local database;
  • The data is transferred to the WMS system;
  • The parcel is sent to the main conveyor;
  • Should there occur a barcode reading error, the parcel is rejected and the operator manually reads the departure code;
  • The operating modes change is carried out by the operator via a computer with a monitor and a control system located in the vicinity of the system.
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;
  • Sick barcode scanning and dimensioning equipment set;
  • Industrial computer.
Result

Benefits obtained:

  • reducing the human factor role;
