Check Weighers
















Weight variations is a major concern for  bakery manufacturers
.It could be due to Dividers malfunction in bread , buns manufacturing  or Cutter /Moulders setting in  
biscuit production lines .It could be due to Dividers malfunction or Cutter /Moulders setting or
configuration . The major steps is to rectify the problem in the equipment first but  for detection
purpose bakery plants  install    in motion checkweighers after packing section  in biscuit
manufacturing and checkweighers at dividers end to measure the weight of the dough piece
.Installation of checkweighers  would   make the conventional table top scales obsolete   at some
places . These checkweighers helps bakery manufacturers in two ways.














Under weightYou can be  sure of the weights  products which comes through check   weighers  and its
legal requirement for all manufacturers to adhere to the declared weight with some tolerance s.

Over weightAny variation of weights whether Under weights or Over weights  does harm company
interests . Corrections can be done  at manufacturing areas to get the proper  weight of the product
Working Principle of CheckweigherWork on Pneumatic  applications,  pneumatic cylinders are used
for retraction or  folding of conveyors  for rejection of packets. Product s are put on the conveyors
which have load cells which gauge s weight and send signals to the  pneumatic cylinders  which  are
activated through  .valves  compressed air  then either retracts or pushes the folding conveyor or
some checkweighers have pneumatic nozzles on the conveyors surfaces which pushes the under
weights and overweights through blast of compressed air   .Which drops the under weight or over
weight packets . One has to check  the packing machine output to synchronize  with check  weigher
.Specification of Check weighersProducts/per minutes- packets/minSet Weights = +/- gmsTolerances
=+/- gmsAir Pressure = kg/cm2


Major manufacturers of  checkweighers

Mettler Toledo

Ishida

Lock Inspection

Sartorius

Wright Machinery


Check weighers now days  have data storage where all details of  weights of the product can be
stored and can be  retrieved analysis.Any variation of weights whether Under weights or Over weights  
does harm company interests . Corrections can be done  at manufacturing areas to get the proper  
weight of the product.
