2.2 Canisters (Figure 2) The canisters (1) are of different capacities and are suitable for containing the product to be dispensed. The canister is equipped with one stirrer with slanted blades (2), powered by one d.c. motor (3) attached beneath the canister itself. The 5-liter canisters contain two stirrers controlled simultaneously. According to the type of canister, one or two filters (4) are present, that serve to trap any impurities that may be present in the product.
If the volume required for dispensing is less than the maximum volume of the bellow pump (approx. 10 cc), a fraction of a dispensing stroke (compression of the bellow pump) is sufficient to dispense the requested amount. If the volume requested for dispensing is greater than the maximum volume of the bellow pump, it will be necessary to: carry out a complete dispensing stroke (compression of the pump) –...
2.5 SAPS on-board electronics Each SAPS is equipped with an electronic board, attached in the lower part. The control electronics differs based on the type of circuit: sequential or simultaneous. CBModule (sequential circuit) CBSlave (simultaneous circuit) Figure 7 Figure 8 The CBModule board is connected to the CBMono The CBSlave board is connected to the CBMaster board and to the CBMB board.
3 CONTROL ELECTRONICS 3.1 Introduction COROB™ automatic dispensers are managed and operated via a a dispensing application software installed on the management computer. The management computer sends high level commands to the machine firmware installed in the different control boards. The presence of some electronic boards depend on the type of dispensing circuits and optional the machine is equipped with.
3.2 CBMaster The CBMaster board is the interface between the computer and the machine and generates the signals necessary for the built-in machine electronics to execute commands. The board receives the commands from the computer via serial port. The commands are interpreted by the management firmware.

For bellow pump dispensers, it is necessary to use Standard (Bellow) as pump type. It is also necessary to enable the option Automatic change recalculation. To create a different pump type, suggested only if you need to dispense quantities lower than 0.1 ml, refer to the CorobTECH user’s manual for more specific information.
5-10 Using the Dispenser commands… window in CorobTECH, check that: • all the circuits are working properly; • the Autocap, if present, opens and closes smoothly; • the Shelf is moving up and down and the punching, if present, is working. In case of errors during this checks, refer to the section “Troubleshooting”.

5-11 finish refilling the canister, by pouring at least 1 liter of colorant. – From CorobTECH, send the command to expand all the bellows pumps of the machine: use the Reset or the Bellows > Down command. Repeat Bellows > Up and Bellows > Down commands at least 3 times. During this operation: - double check that all the colorants are filling the pipes and flowing out of the nozzle - double check the absence of leaking in FEDV area...
5-12 5.8 Moistening the cap sponge Installation now requires that you insert the sponge in the humidifier cap and moisten it for the first time. The sponge is available among the material supplied. The sponge serves to keep the dispensing nozzle center at a moisture level to prevent the colorant from drying out.
6 CALIBRATION 6.1 Concept Calibration is the procedure for determining the parameters needed to regulate the dispensing process, thus granting machine accuracy. The aim of calibration is to obtain a correlation chart between the volumes that we want to dispense and a parameter that can be regulated by the machine.

9000 8000 7000 6000 5000 4000 3000 2000 1000 Offset Dispensed volume (ml) For bellow pumps technology, the Offset is always a positive value and it is mainly related to the rheological characteristics of the fluid and to its elasticity. This model still supposes that, once the colorant flow has begun, the volumetric efficiency is constant, whereas in real working conditions we have to consider that this is not always true;...
Page 59
The model used is complicated a little more by the fact that we need to use different speeds to dispense different quantities. The definition of different speeds is necessary to obtain a good accuracy on small quantities (using a low speed) and an acceptable dispensing time on big quantities (using a high speed). Normally we use low speed up to 1 ml and high speed for quantities higher than 1 ml.
As understood from the previous considerations the model is quite complicated and it is strictly connected to the firmware developed for this machine; therefore it is kindly suggested not to change the above shown file. This calibration file has to be used for both 2.5 l and 5 l circuits. The only value that can be necessary to change is the minimum volume dispensed.
The CorobTECH program allows you to automatically calibrate the machine starting from theoretical calibration parameters. The main steps are: Connect the scale and place it on the machine shelf, under the nozzles, taking care that it is in stable conditions (no draught or wind). Place an empty can on the scale, as for normal dispensing.

The following are the most important parameters to check during the calibration or right after: Volume dispensed at 8000 steps Flow chart 1 Standard deviation values Flow chart 2 Offset at low speed When calibration is over, send the command Dispensing test to verify the calibration just carried out.
