  1. Hi

    Thank you for your answer.
    The first day produced only one product in multiple cycles (20-30) so that rest does not affect the composition of the recipe.
    The problem I solved by, the actual value of scale (ML0) stored in the variable ML25 ,when finished the cycle, the value of ML0 record as a "rest" in a separate variable ML36 (pressing the "discharge ends") and subtract it from the variable ML25 and stored in a new variable that we show on the display (ML44). All the time weighing variable "rest" is subtracted from the Variables ML25 and the end of the cycle recording real value scale (ML0) in variable "rest". I hope that I managed to explain my decision. Excuse the bad English

  2. Thank you for expressing their desire to help

     
    Mixer is set directly on the scale (cell), sets the weight of the mixer, a backlog of dust and waste are zeroed. In one day mixer produces one type of product. After each cycle, which lasts for one hour, re-charging according to the same recipe.
    The following day it is another product and other recipes.
     

    The rest of the product is less than 25 kg workers are not inserted in the bag, he remains in the mixer. When you initiate power-up the next charging cycle, the rest of the weight scale continues to read, automatically the first component will be less of the weight of the rest
    for example:
    at the start of scale is 0
    From the first tank is dosed 150 kg according to recipe
    When the scales show the 150, starting the dosing tank 2
    From the second tank 145 kg
    When the scales show 295 (150 + 145), starting the dosing tank 3, etc.
    From the third tank 220 kg
    From the fourth 20 kg
    From the fifth 10 kg
    Total 545 kg - when mixer complete mixing is packed in bags of 25 kg
    545/25 = 21.8 - bag - the rest of us 20 kg
    Start the next cycle on the scale shows 20 kg and should be zero
    From the first tank will be filled up only 130 kg, and should be 150 kg

    I hope that is clearer

    I tried to add sequences that surplus (example: 150 + 20) or at the end of the cycle we say the rest of the 15 kg (25 kg bag filling has a tolerance of + -2%, the rest is not always the same) again have to bring balance to zero.

    best regards

    maybe from wood can not see the forest

  3. Hi,
    I work program for the mixer of powder adhesives and mortars, capacity is 2 tons, complete mixer is set to weight load cell, the mixer is filled from five silos, scales I set the two points, I set the zero and tare, program works very well .PLC (v570)more I have not installed, all functions of trying on the desk and scales I adjusted in grams to be easier to work with simulations of charging and discharging.
    So I came to a problem because workers empty mixer in 25 kg bags.

    In the first case: Mixer can not throw out the entire material, remains undetermined amount of material of less than 25 kg.
    in the latter case: In a mixer remained quantities of less than 25 kg (23,16,18,5 kg) which is insufficient for filling bags.
    I'm interested in, in any way solve this problem, because the residual quantity in the mixer affects the recipe of the product.
    How do automatic "tara" after every discharge mixer. I had some ideas that were not correct. The requirement for "start" I chose to value the balance is enough for about zero
    I ask for a little help

  5. Hello everyone

    I'm working to improve on old machines with upgrading PLC

    No objections, I found an excellent solution price / possibility / requests Orderer
    I built a couple of models V570, users have a very solid approach to use, given the conditions in which they are used.
    Here is a positive story, the paper cutter that was destroyed in the floods in Bosnia in 2014, removed the complete original electronics and set V570.
    The machine successfully rescued.
