Abstract

A surge suppressor 13 for a whipper motor 1 in a drink vending machine prevents electrical surges being fed back to a VMC (Vending Machine Controller) or I/O board. Surges from a whipper motor may cause random energising of outputs and general corruptions. The surge suppressor may comprise capacitors 5 and a resistor 6 in parallel with the capacitors. The surge suppressor may be connected to earth. It may be mounted internally to the motor, or externally.

Description

Whipper motor surge suppressor for vending machines This invention relates to motors used for mixing drinks in vending machines commonly referred to as a whipper motor.
When water and powder or granules are mixed together in a vending machine to produce a drink, a whipper motor is used. This helps to achieve the following:- 1. Mix the drinks to ensure all powder and granules are dissolved in to the drink.
This helps to ensure product and taste consistency.
2. It can be used to present a drink differently.
3. Ensure large amounts of powder can be mixed with the smaller amounts of water without the mixing bowls and associated chambers and pipes becoming blocked.
Over time the seals used to protect the motor from the drink during whipping can wear, allowing moisture to seep back in to the motor. Also, during times when there are large amounts of powder being added to the whipping chamber, this puts the motor under sudden stress and greater load. These conditions may cause the motor to send an electrical surge back to the Vending Machine Controller (VMC) or the Output (I/O) board causing the VMC or I/O board to behave abnormally and energise random outputs when they should not be energised.
The most common problems are, but not restricted to: 1. Premature cup transfer, causing the cup turret to try and load the next stack of cups before the current cup stack is empty. The turret jams the current stack of cups preventing any further cups from the current stack to fall down in to the splitting area. Also known as over indexing.
2. Premature powder dispense, causing random ingredient motors to energise and dispense dry powder in to mixing bowls. The next time water is added to the mixing bowl during a normal vend cycle, the bowl or chamber will block.
3. Otherwise unexplained boiler overflow.
4. Random cup dispense of a single or multiple cups.
5. Audit corruptions.
6. General operating system corruptions.
To overcome this, this invention proposes to add a surge suppressor to each whipper motor.
The surge suppressor will ensure that all power surges generated by the motors will be absorbed by the surge suppressor, and then discharged back into the motor during normal operation ensuring the power surge will not affect the VMC or 110 board.
Preferably the surge suppressor will be fitted as close to the motor as possible although it may be fitted anywhere between the motor and the VMC or 110 board.
This may be added to the motor internally or externally.
Preferably the surge suppressor will be connected to earth if the motor is earthed.
This invention will now be described solely by way of example and with reference to the accompanying drawings in which: Figure 1 Shows the current standard whipper motor configuration.
Figure 2 Shows the whipper assembly including the surge suppressor which could be used.
In figure 1, a whipper assembly (12) in which a whipper motor (1) drives an impellor (9) on the motor shaft (11) through a back plate (10) in a whipping chamber (8) to mix the water and powder coming in from the mixing bowl (7). The motor is connected to the VMC or 110 board via the live or line (2), Neutral or Common (4) and the Earth (3). The earth connection is optional depending on the motor supply voltage and voltage type either AC or DC.
Figure 2 shows the whipper assembly with the surge suppressor (13) fitted. There may be 1 or more capacitor/s (5) fitted to a surge suppressor. The capacitor/s may either connect across live and neutral or connect across live and earth, and neutral and earth.
This will usually be dictated by the motor configuration in relation to the vending machine. An example of this would be if the motor is earthed or not. There may or may not be a resistor (6) fitted. If there is, this would usually connect in parallel to the capacitor/s. This will usually be dictated by the motor configuration in relation to the vending machine. An example of this would be if the motor is earthed or not.
The type of surge suppressor to be fitted will depend solely on the motor type and voltage used for the specific vending machine it is being added to.
The surge suppressor may be any shape or colour. The surge suppressor may be mounted internally or externally. The surge suppressor may be manufactured into a single unit or component for ease of fitting, but this is not essential.
Ideally the surge suppressor will be fitted with piggy-back terminals for ease of fitting and replacement of whipper motor or surge suppressor on site without the need to break the wiring loom. The surge suppressor should be fitted as close to the whipper motor as possible for best results, although anywhere between the whipper and VMC or 110 board is possible. Maybe the surge suppressor could be integrated in to the VMC or I/O board.
