Hello everyone,
I am a newbie in automation stuff and i wanted to do a simple thing with just a sensor, a blade and a plc.
My aim is this - The chocolate bar will come in and my sensor will see it. After my sensor sees the chocolate bar i will give a command in plc that will release(cut the bar) and bring it the blade up. This process will continue on until the chocolate bars are over. The conveyor will not stop at all so bars will keep on coming and the blades will keep on cuttin .
Now i have some big problems with this tho.
My first problem - I didnt work with any sensors before so i dont know how to make that happen. Both the sensor and the blade is digital signals so i dont need to work with any analog scaling or stuff like that. Thats why i said this will be a simple process. But i need some kind of reference or example. I am thinking of doing simple stuff like put a condition(sensor energized or not) and if its energized release the blade and pull it back up. I wont need any alarms or stuff like that since this will be for myself but in the future if i need stuff like that i would do upgrade the system :nodi: .
My second problem - I said
My third problem - What kind of sensor would i need? This is not that important since i have time to search up my sensors but if anyone used sensors for this type of stuff i would like to know
My last and probably biggest problem - How will the sensor be de-activated or reset? I have couple of options here. Let me put a hypothetical scenario to the table. Lets say i put my chocolate bar on the conveyor and turned it on. And my sensor sees the bar and my blade cuts the bar. Now the way i see it i can do two things. First is - dont do anything to the sensor. This will probably end up in chocolate bars getting cut to tiny pieces but to counter this maybe i can put a small delay to my blade going back up so my blade can hold the bars for a small amount of time so that my sensor has time to reset itself. My second option is - do not mess with the timers or stuff like that and just let it roll, the blade's up and down movement give brief openings for sensor to reset by itself and i wont need to do anything.
Can anyone help me?
Thanks for reading and for helping.

. Now this brings up another set of problems. How will i do that exactly? i mean i just put a condition and say like, hey if the sensor is 1 than just turn the blade 1 and than instantly make it 0? Or is there some sort of function block or smthng like that i can use for this type of thing? Maybe ONS- one shot? i do not now.I am thinking of doing simple stuff like put a condition(sensor energized or not) and if its energized release the blade and pull it back up.
