Pneumatic Torque Limiter

Sandeep,

"Some times its nozzle never match with the jar necks still its come down and spillage of oil occurred on machine and conveyor"

Are all six of the bottles sometimes not lining up with the fill head? Are a few of the six bottles at a time not lining up with the fill head? Is the device that sets the spacing between the bottles on the conveyor functioning properly?

Is this a new conveyor line? Did this problem just start recently on an existing conveyor line?

Assuming that the conveyor moves the bottles to the fill position and the fill head assembly is stationary except for up/down/up (pre-fill/fill/post-fill), are the prox sensors on the conveyor set properly to detect the bottle position at the fill head assembly?

Are there provisions available on the conveyor rail and spare PLC inputs to install more prox sensors to provide "bottle misaligned with fill head <no fill>" and "belt micro jog adjust<align bottle to fill head>" signals if the bottles are not lined up with the fill head assembly properly?

"Is there any torque limiter system or something which can make machine nozzles to go back if its stuck to the neck of jar"

If the case is that the nozzle(s) are getting stuck in the neck(s) of the jars (too much down stroke), adjust the down stroke on the filler head, either through the PLC or mechanically.

Who is the manufacturer of the filling line?

Provide more information. Someone may then be able to help you.

Why not just fix the conveyor to stop at the right place?

As KJK/USA said, more information.

The system logic should be arranged so that oil flow doesn't begin until the nozzles are fully down. Assuming that they are hitting the bottle necks before reaching full stroke, there should be no flow (I'd expect the system to stop with some alarm signal and error message).

Make sure that the sensor for "nozzles down" isn't being triggered until they are in the correct position - this should stop some spillage.

You still have to fix the more fundamental problem of the misalignment, though.

Dear all,

JohnDG is right.

I have to make sure even sensor is there or not.

Also I have to fix the more fundamental problem of the misalignment.

Even whatever posibilities KJK/USA said all are there.

Once KJK/USA said all those possibilities means he knows the solution for it.

Please tell me.

Please tell me one example of machine so that i can compare and tell my management

My machine manufacturer is Spanpack.

May be manufacturer dont have problem our management choose cheap machine so they avoid more synchronization and safety.

Thanking you.

Please reply.

Do you have an engineer on site?

No

But I think if I fix reed switch on down position of Pneumatic Cylinder and get the signal from it for filling. Then oil will not start to fall when nozzle stuck to neck.

Will it work?

Please suggest.

That should fix it. Can you locate the switch? Is it the type that has an indicator to show when it's on? Makes life a lot easier if it is, especially if you can manually lower the nozzle assembly (with the air off!).

Just re-read - maybe I've misunderstood. Is there already a switch, or do you intend to fit one?

I intend to fit one

Do you have circuit diagrams? Do you know where to wire the switch in?

I talk to their Engineer. He said its possible.

Let him try. then I will contact you.

I think its just to fix reed switch and programm the PLC.

Thank you.

Consider the AMC Pinspotter machine for bowling alleys, an American pastime. There is one part of the machine that aligns the bottom of the pins for proper placement, and another that picks up/replaces the pins. I'm sure it's a lot of micro-switches and logic circuits.

Sometimes it takes two machines in concert to accomplish a task. One machine makes sure the bottles are in place, and the other fills them when it gets the OK.
