Hanger Bars x2 Hanger Plate x2 The Load cell Top Box Assembly houses a precision load cell mechanism The load cell is a precision electronic weighing instrument and provides all the fundamental weight signals to the machine controls It incorporates an integral overload facility that helps to avoid accidental damage due to excessive loading The overload system is factory set but may require future adjustment This is largely dependent on the loading exerted on the weighpan and should only be adjusted by an Trained Engineer The overload system will not protect against shock loading therefore the Load cell unit should be treated with care The Load cell is a sealed unit no user adjustments are required for the Load cell Mechanism Always ensure that prior to moving the machine the Weighpan Assembly is removed from the Hanger Plates Failure to do so can result in shock loading on the load cell component which will severely impair the machines performance COTSWOLD MECHANICAL LTD Unit 4 Chancel Close Eastern Avenue Gloucester GL4 3SN TEL 01452 309944 FAX 01452 306644 http www cotsmech co uk Email enquiries Ocotsmech co uk 17 COTSWOLD MECHANICAL LID Weigh pan Assembly Weighpan Body x1 Weighpan Spacer a x4 Rose End Bearing x2 SA LI a Pr Weighpan Lid af ei Strap x2 LV 2 fe Cylinder Rod jie A E A DAA Extension x2 RS Wes Pneumatic oo IN Connector y W j Weighpan Lid o A

The overall spring thickness needs to be decreased by either removing changing the spring thickness combinations If the tray amplitude decreased when the bolts were slackened then the vibrator springs are too weak and the overall spring thickness needs to be increased again by adding changing the spring combinations Step 6 Vibrator springs are available in three thicknesses 7 9 amp 11 ply Adding or replacing springs should take place one at a time When a spring combination has been altered check that the M8 retaining bolts are tight and repeat the amplitude measurement test again return to step 2 as many times as necessary until the correct amplitude is achieved Step 7 Once the correct amplitude has been achieved reduce the vibrator load speed in increments of 10 in the machine controls If the speed of the vibrator experiences a larger than 10 decrease in speed when a 10 speed reduction is inputted via the machine controls the vibration range needs altering This is achieved by altering the combination of springs used to that of a slightly thinner combination 1 e remove one 11 ply spring and add two 7 ply or one 7 and one 9 ply Essentially having previously achieved good amplitude of vibration the vibrator is now being restricted or de tuned in its overall performance in order to gain good linear range of control Overall tray speed is therefore a trade off over good linear range of control Be aware that below 40 load spe

71. r Tuning The V1 Vibrator Unit will have been tuned prior to leaving the factory and should not require adjustment However over a period of time the performance of the Vibratory V2 feed unit may diminish This is usually after a period of eight months or more and is more noticeable on applications requiring high vibration speed and amplitude to move the product Leaving the vibrators running at full load speed when a machine is empty or during a wash down can also exacerbate the condition Tuning is a relatively simple process and basically involves selecting the correct combination of fiberglass springs to replace those already on the unit The springs are supplied in three varying thicknesses 7 9 and 11 ply The object of successful tuning is twofold 1 To obtain approximately 4 5mm 5 0mm of displacement movement on the top plate of the vibrator unit WHEN A TRAY IS LATCHED IN POSITION and the unit is running at 100 2 To obtain good linear vibration range This is determined by reducing the vibrator speed in the machine controls in intervals of 10 from the full load speed of 100 If the speed of the vibrator experiences a larger than 10 decrease in speed when a 10 speed reduction is inputted via the machine controls the vibration range is deemed as bad However often there is little vibration below 40 and these low end values are largely ignored The procedure for tuning the vibrator units are as follows M8 PLAIN WASHER STAINLE
