AE-PLC-SLB 球体选择工作站

The Ball Selection Workstation, "AE-PLC-SLB", designed by EDIBON, is a ball selection system commanded by a PLC. The workstation detects balls that arrive to the collect position and, according to the color and material, a cylinder guides the balls to the correct container. The system is equipped with different sensors in order to identify the balls.

The "AE-PLC-SLB" workstation is designed as a modular system to facilitate the understanding.

The main components are:

• The PLC: is composed of the CPU unit and all additional modules needed to ensure the correct operation of the workstation.
• The Control Panel: with start/stop button, emergency pushbutton, reset button, light indicators to show the current state of the process, etc.
• The Pneumatic Circuit: contains the required solenoid valves, pressure components, filters, and regulators to ensure the proper functioning of the unit.
• The Workstation: is composed of real industrial components used by rotary table systems such as reed sensors, presence sensors, DC motor, inductive sensors, rotary table with 8 positions, etc.

The pneumatic circuit and the workstation are distributed in the following sections:

• Air Treatment System: contains a filter-regulator block with a water trap and shut-off valve to control the air pressure input to the unit. Includes a dual-scale pressure gauge to visualize the pressure level supplied to the unit.
• Parts Feeding Section: contains a sloped ramp for storing the parts. The parts are supplied to the unit one by one through a double-acting cylinder. Each of the two inputs of the double-acting cylinder has an adjustable airflow valve with a bypass to regulate the cylinder speed.
• Parts Verification Section: designed to classify the parts, the four parts with different characteristics will be classified into four storage areas by activating three actuators. The three sorting actuators are double-acting and each has an adjustable airflow valve with a bypass and a pilot-operated check valve to regulate the cylinder speed and block its position in case there is no air input in the double-acting cylinder.
• Parts Sorting Section: designed to classify the parts, the four parts with different characteristics will be classified into four storage areas by activating three actuators. The three sorting actuators are double-acting and each has an adjustable airflow valve with a bypass and a pilot-operated check valve to regulate the cylinder speed and block its position in case there is no air input in the double-acting cylinder.
• Signaling Tower: contains green, yellow, and red LED lights to indicate the system’s status.
• Solenoid Valve Block: it is a distributor block of pneumatic valves with twelve solenoid valves, two of which function as 3/2 monostable solenoid valves, six as 5/2 monostable solenoid valves, and four as 5/2 bistable solenoid valves.
• Electrical Terminal Block: contains all accessible and identified unit signals for manual unit checking. The electrical terminal block has color-coded terminals to help the user identify the type of each signal, and it also contains the name of each signal.
