The roots of the toilet may go back into the Minoans of Crete that is ancient, but whoever invented the toilet will be astonished to see that the innovation is becoming. To maintain the generation of commodes, Phoenix Automation a Norcross assembled an automatic machine which builds around 24,000 finished 40 seats weekly, or even bathroom seats each 10 hours.
The whole system includes 23 motion control servo drives, 2 cameras, nine 16-valve atmosphere banks, greater than 300 photocell and proximity detector inputs, and four Siemens HMIs (Fig. 11), all controlled by a Siemens S7-318 programmable controller (PLC) and most of communication via Profibus.
The challenge
Our engineers recognized that one key to this assembly procedure was supposed to utilize vision systems to find coordinates to have the ability to place the parts after a system integrator, Phoenix Automation, won the contract for the project. The next obstacle was to obtain a vision system which couldn't just take care of the production rates involved, but also integrate with this automation system's remainder--such as the controller along with motion-control servo drives. The vision system was that the Siemens VS710. It had a Profibus interface, but also fulfilled with our performance and precision specifications.https://medium.com/@toiletszones/how...t-1297a73dd4df

Locating the holes
The toilet seat's assembly necessitated two sided pallet conveyors that move the covers and seats. The task was supposed to put bumpers into holes which are molded to chairs and the bathroom covers.
The grid finds the bumper holes, as one point travels down. The vision system describes the positioning of the holes using blob investigation in combination with the pixel matrix of the system. The holes are redrilled to clean the paint out since the holes fill paint. The procedure demanded the grid also to coordinate a method to find drilling heads over every hole and also to discover the holes then place servo controlled grippers to set the bumpers to the holes that were redrilled.
Simultaneously, its line travels down where a vision system finds the chair holes, and the other movement control system puts bumpers from the pockets.
Since a toilet seat isn't a accuracy thing, the vision system must takes into consideration a specific quantity of variance in gap positioning. The data for every hole organize is sent at 12MBaud within Profibus system into the management system. The information packet includes simple information which makes it possible for the movement control systems to index-Click Best flushing toilet (Best flushing toilet - Facebook).
Each conveyor system has channels that perform tasks like bumpers, attaching hinges drilling screw holes, setting parts for assembly inspecting ethics, and marrying of the parts.
Technical help a must
The assembly system involves these elements: a Siemens S7-318 programmable logic control (Fig. 12), two eyesight technology channels configured for notebook computers, a mobile operator port which could plug into any place in the machine, multiple motion control drives and motors, and two vision systems, the above Profibus technology and information system that connects each these elements in addition to the I/O systems.
Control Corporation of America (CCA) at Norcross, GA aided with all the configuration, support and specification of their PLC-based management gear. Phoenix Automation had not used Siemens' equipment. Significant from the selection procedure has been the capability to provide aid of the distributor. At this project's beginning phases, Phoenix requested CCA to help examine the camera. The evaluation was setup by CCA within a quarter hour with an algorithm at the camera.

An integrated solution
The toilet seat procedure that is automatic employs an option from CCA, Phoenix and Siemens. Operator interface has been achieved using all the Windows CE-based MP270 HMI. The vision system was integrated to offer an reliable and accurate system that was targeting. Performance Model 1FK6 servomotors and 6SE70MC movement control servo drives united to get a movement system that is responsive and strong. All movement functions were coordinated into the 6SE70MC Masterdrives across the community from the S7-318 PLC. The result was a really impressive manufacturing option, which has revolutionized the art of toilet seat(Website:Toiletszones.com) meeting for the client of Phoenix Automation.
Greater productivity
Together with the manual assembly platform, it required a change of at least a hundred assemblers functioning at work stations and drill presses to create the number of components the system generates with just ten operators in the period of time.
After obtaining customer consent using a manufacturing run-off and staging the system, the system has been sent to the plant of the bathroom seat manufacturer. Startup issues were minimal since it was tested before sending.
The system is cranking out.
