Week #4: (10/30-11/3) Ladder Diagrams, Visio, Ch. 7 & 8.

Post by rjagodowski »

Monday, 10/30: Discuss ladder diagrams and problems from Week #3 handouts.

IMPORTANT: The second "quiz pack" was distributed in class today (10/30) and will be due before noon on Monday, 11/6. If you did not pick up a copy, please see me on Wednesday, 11/1.

Wednesday, 11/1:
Basic Hydraulic & Pneumatic Symbols and components. We'll start the discussion by working through this tutorial Comparing Hydraulics and Pneumatics.

In-Class Visio Assignment:
The second half-of the class we will work on a Visio Drawing Ladder Diagram Assignment which will be distributed in class. A pdf of the assignment is attached here for your convenience:

Friday, 11/3: We will continue with some discussions on pneumatic and hydraulic components & diagrams. We will also look at MS Visio again to create a simple fluid power diagram.

In-Class Visio Assignment: Here is the assignment to create a Pneumatic Dual Acting Cylinder Diagram in Visio. NOTE: The control valve was created out of the Visio symbol library and then "Grouped" into a single component. See the assignment sheet below. This assignment will be distributed in class on Friday, 11/3, and is due no later than 4:00 p.m. on Thursday, 11/9. A pdf is attached for your convenience:

As an FYI, Here are a few tutorials on Pneumatic Components:

Pneumatic Directional Control Valves

Pneumatic Schematic Symbols & Flashcards

Control of a Reciprocation Circuit.

To put some perspective on the technical diagrams and content we're learning, I thought this might be a good time to show a recent senior project.

Here is a YouTube video of the Spring 2015 Senior Advanced Automation Bottle Filling Project. Note the use of electrical, pneumatic, robotic, microcontroller and PLC (programmable logic control) components in their project. An electric screw-drive motor feeds the empty bottles. Pneumatic cylinders are used to push & position the bottles into the proper position. A microcontroller is used for table rotation control. An electrically controlled fill valve is used to control the fill of the bottles. A robot is used to screw on the caps. The end-effectors of the robot were made in-house with a Makerbot 3D printer. Pneumatics control the bottles as they drop into carriers. The entire process is controlled by a Click PLC.
