Accurate Positioning
Dear manikandan
Please tell us your requirement in detail. So that proper system can be suggested
instead of servo motor belt can be correctly stoped at axect position by sensors.
YOu may use ball screw type lieanea drive in case your length of conveying is less than 3 meters and very accurat positioning is required

Re: Conveyor With Servo
Dear Mr.Singh,
Small slits will come on that conveyor. I need to place the slits on pallet. second set of slit will be placed 50mm right to the left tip of first set. it will goes on for 5 sets. again it will start from the startin point.(as a first set).
for this I'm looking for belt with grooves. if grooves are there, I can push the slits to the pallet with separate pushing arrangements.
Thank you.

Re: Conveyor With Servo
Hello Manikandan..
Not terribly sure what you are trying to do, but I get the feeling you need to index your conveyor.
This you can do with a one way coupling on the drive pulley shaft with an arm on it so it acts like a holdback.
The end of the arm on the one way coupling is connected to a crank shaft via a connecting rod.
As the crank rotates, the connecting rod alternately pushes and then pulls on the end of the arm on the one way coupling.
Since it is a one way coupling, the belt will move forwards for 180 degrees of the cranks rotation and will stop dead for the other 180 degrees of crank rotation.
By adjusting the effective length of of the arm on the one way coupling, you can adjust how far the belt moves each revolution.
Hope this is in some way vaguely relavent.
Regards

Re: Conveyor With Servo
Without knowing a lot about the details of your project it is difficult for us to give anything more than general replies.
What is the belt speed?
Can it be slowed down just prior to stopping at the correct point?
If so you could look at a VFD on your conveyor drive and utilize 2 sensors - 1st one to detect material coming into the zone and slow down the conveyor and the 2nd to stop the conveyor at the exact point that you want. Adjustments can be made by the timers in the VFD or in the locations of the sensors.
Good luck,
Gary ■

Re: Conveyor With Servo
Hi,
This project is the automation slit collection system in a Transformer industry.
Existing system:
Cut to length machine. after the shearing operation, the slits are travelling on a Flat belt conveyor and to the collecting table.
now one operator collect the slit from the collecting table and place it on the pallet as I said already.
//First set of slits placed in a exact center of the pallet.second set of slit will be placed 50mm right to the left tip of first set. it will goes on for 5 sets. again it will start from the startin point.(as a first set)//(slit lengths also continously varying by +5mm each).
Proposed one:
by automatic collecting system, man power can be reduced also accurate positioning is possible there.
//for this I'm looking for belt with grooves. if grooves are there, I can push the slits to the pallet with separate pushing arrangements.//
Thankyou Mr.Singh, Mr.Graham and Mr.Gary.

Re: Conveyor With Servo
Dear Manikandan,
A servo motor, such as Siemans, can be used for this application. Also, you would be well served to use a toothed belt against a corresponding toothed pulley to guard against slippage. There are a number of suppliers of this type of equipment (such as Bosch).
If you require greater control and the travel distance is relatively low, consider using an encoder to control the movement.
Good Luck with your project. ■

Conveyor with servo
Is it possible to use servo motor for flat belt conveyor (very accurate position stopping is needed)? how to arrest the slip? or any other belt can I use? like timing belt....if so please let me know the design procedure. ■
