Motion Control Sure Step Stepping System Video 5 of 5. Looking for help integrating industrial control components into your next Motion Control application? In this video (5 of 5) we show how an AutomationDirect SureStep Stepper System is used on a Rotary Index Table Station to rotate a slotted disk to dispense a combination of different colored glass marbles, brass balls, and steel balls, one at a time from a part hopper.
This LEARN video covers the Rotary Index Table Station that uses the Do-more H2 Series PLC. A C-more Touch Panel is used as the operator interface. Various sensors are also used with the Rotary Index Table to control operational functions.
The Rotary Index Table is the second stage of an overall application based on various Motion Control systems. The first and second stage are controlled with SureStep Stepper Systems using ADC products, with the final stage based on AutomationDirect’s SureServo Servo System.
Follow to the other videos in this 5 part series.
In this final video we will give a demonstration of how the Rotary Index Table operates. Let's take a look. Here is a list of the functions that will be demonstrated. Let's first start the Part Feeder. The Part Feeder was covered in another video on Motion Control. The input tube to the Rotary Index Table fills up with the marbles and steel/brass balls. We will refer to these, for the most part, as the parts. The laser distance sensor will detect when a part is loaded in position 1. Next the control system is placed in Auto Cycle and the Cycle Start pushbutton on the C-more is pressed. If everything is OK, the rotary disk will index 45 degrees. This operation will continue until no more parts are loaded, or the Cycle Stop pushbutton is pressed, or the system is taken out of Auto Cycle. If a Steel part is detected at position 2, a one bit is loaded into a shift register within the Do-more ladder logic, and then when indexed to position 3, the Steel part reject slide gate cylinder solenoid will energize, and the steel part will be dropped into the reject bin. Please note that position 4 is idle at this time with no operation taking place. Here we see a part indexed into Position 5 and the color detector is triggered to take a color reading. The results are stored into three shift registers to track the color until the part exits the system three positions later at Position 8. If a Brass part is detected at position 6, a one bit is loaded into a shift register within the Do-more ladder logic, and then when indexed to position 7, the Brass part reject slide gate cylinder solenoid will energize, and the steel part will be dropped into the reject bin. At Position 8, the part exits the system, with the color that just exited being displayed on the C-more Touch Panel. Here we put the control system into Manual Cycle, and by pressing the Table Index pushbutton on the C-more Touch Panel, we cause the rotary disk to move 45 degrees in a counter clockwise direction. Also in the Manual Cycle, we can use the one degree counter clockwise and one degree clockwise pushbuttons to jog the rotary disk to a known starting position. The Trigger Color pushbutton can be used at any time to take a reading from the Color Sensor. While in the Manual Cycle mode, we can operate either the Steel Ball reject slide cylinder or the Brass Ball reject slide cylinder as demonstrated here. Well, that wraps it up for this series of videos on Motion Control. Please visit www.automationdirect.com for all of your automation and control needs. Thank you for watching!
