This project (hopefully the first of many), will be based on making an alternative designed 'check weigher' for my very small factory. I need to take a minimum of 50 bottles per day off of my conveyor belt, weight them on a load cell, then have that weight automatically recorded and alert me if it is out of tolerance. The bottle must then be put back on to the conveyor belt.
For the initial prototype I would need a simple Bill Of Materials to be created using [login to view URL], and assistance with the PLC programme. I will be using a Siemens Logo 8 most likely, but Arduino or other alternative systems would be OK too. We are looking to strike the best compromise between price and functionality.
I would ask you to look at my initial ideas, make them better where possible, and then help me to design the hardware set up that is needed to operate it. If you think that there is a better way of doing what I'm aiming for then we can start from scratch!
It is quite simple stuff (in my opinion). My initial (untested) thoughts were that I could set up a couple of pneumatic pistons to act as gates on the conveyor, (running 1,000 to 2,000 bottles per hour) then push a bottle on to a load cell adjacent to the conveyor (while releasing the gates to allow the other bottles down the line), have the load cell record the weight and alert me if it is outside of tolerances, then push it back on to the conveyor. As we would only be needing to weigh 50 bottles per day the requirements of the hardware should be quite low.
Some parts will undoubtedly have to be hand fabricated here in-house.
Alternative ideas are most welcome.

Dear Sir,
This is Ahmed Hamdy, a Product designer and manufacturer. I have a wonderful experience in the field. I made many products before but the good news that I can either design and manufacture all plastic enclosures. I'm a Sr. Lecturer at the American University in Cairo and I have my own factory where I can manufacture everything. this is why I hope to be selected for this wonderful project. Thank you sir in advance

Hi. Interesting project. I congratulate you on your initiative. I understand what you want to do and I think your initial idea is very good. However, based on your idea using a load cell and pneumatic actuators, I have a proposal that could perhaps work. I am not so concerned about the automation part and the electronic design, but rather the mechanical and pneumatic part because I do not know the variables of the process. You mentioned that you could work with a speed of up to 2000 bottles per hour (1 bottle every 2 seconds), well! It is not so fast, and we can use the pneumatic systems to extract the bottle from the tape without problem (of course with certain mechanism so that the bottle does not fall). A system of two conveyor belts with different speeds can be used using frequency variators to guarantee a certain distance between bottles and facilitate the extraction and then the incorporation of the same.
Questions:
1. Are the bottles full or empty? Is the content liquid or solid?
2. In case of being full of some liquid ... have you thought about the possibility of using sensors to detect the height of the liquid? and from there calculate the weight.
I would like to ask some other questions, but I have limited characters.
If you have any comments or have questions please let me know.

Hi i saw that you need a great design for your company and i am ready to make an awesome looking design
for you. i will give u some options as well please message me so we can proceed
we have Experience of 10+ years in Graphic Designing logo designing
send me a message so we can discuss further
i think your concept is good. but for the improvement, i prefer to use photoelectric sensor for product detection 'cause it's more accurate and stable to detect product. for gate actuators it's called escapement mechanism.
for industrial use i prefer to use smart relay (siemens logo, schneider electric zelio, or omron zen) rather than arduino. because it's actually cheaper to use and it use 24vdc as industrial standard. arduino use 5vdc so you must add another relay.

Hey, how are u? I really interested about project like your. I am looking for something like this for now. I am experienced in industrial automation for global know companies. I have experience with supplying full solutions for factories as well. I know many systems from Siemens, including Logo, S7, Braumat, etc. I know another PLCs, which could be cheaper, but I prefer Siemens for my customers. Let me know, I can send you more informations about me and my work. Cheers!
Hello, if you`re ok with Allen Bradley programming we can discuss about the solution. Other than that I have 8 years experience in pneumatic and electropneumatic systems (using FESTO equipment), and I could surely present a valid solution. Looking forward to hear some more about the project. Kind regards.
