Definitions
- the invention relates to a method for controlling the Walzenanpressung in Walzen ⁇ peelers, especially in KunststoffwalzenClem for peeling rice or other cereal grains.
- roller contact pressure in roller peelers is usually controlled by pressure regulators of pneumatic cylinders of the roller press, wherein the manipulation of the manipulated variable takes place manually, as well as the regulation of the feed quantity of the grains to be peeled, in particular paddy.
- the operator must observe various dependencies with regard to roll pressure and feed quantity, for example between the roll pressure, the degree of skiving, the amount of feed and the current consumption of the motor, whereby a maximum motor current must not be exceeded.
- PN cylinders have considerable friction whose influence falsifies the roll pressing, i. Due to the friction, the pressure force does not correspond exactly to the set pressure values.
- the invention is based on the object to develop a method for controlling the Walzen ⁇ pressing in roller peelers, which allows a more accurate and largely au ⁇ tomatinstrumente control of Walzenanpressung.
- the solution is carried out with the features of claim 1.
- the roller pressure is decisive for the peeling effect in rubber roller peelers. Therefore, the peeling pressure must be very precisely adjustable.
- the roll contact pressure is controlled as a function of a preselected current consumption of the peeling motor in order to give the rolls, in particular rubber rolls, the initial impression of optimal peeling pressure. This can be done by specifying a target pressure, so that the manual operation can be limited to default values, for example, recipes for different types of rice.
- an automatic pressure control on the current consumption of the drive motor for the rollers is possible.
- the control can be done via a PLC / PPS, previously customary contactors omitted. Even at pre- set current value, the Walzenanpressung can still be changed. When the maximum current value is reached, the roller pressure can no longer be increased.
- the pressing of the rollers can be done by means of pneumatic pressure cylinder, but in a further embodiment can be dispensed with pressure cylinder and the Anstel ⁇ development of the rollers done with a servomotor whose stroke is controlled by the current consumption of the drive motor.
- Another object of the invention is to provide a suitable roller peeler thereto. This object is achieved with the features of claim 10.
- Preselection of a recipe is used to read recipe settings on a PLC for the preselection of a starting pressure of a roller press pneumatics of a rubber roller peeler, such as the desired motor current or the minimum and maximum pressure values of the pneumatic system. Possibly. error messages can be displayed on the display.
- the desired pressure force can be preselected.
- the rollers via solenoid valve and pressure regulator with the prescribed in the recipe start pressure or force and the peeler starts with the start of the feed.
- control and regulation functions such as:
- an independent regulation of pressure and / or feed quantities takes place as a function of the motor current or force measurement.
- the current may e.g. be kept constant at a rice variety and a mass flow rate to the peeling degree.
- a coupling of the feed e.g. by means of vibrating chute and the target current at the drive of the roller peeler.
- Parameters such as setpoint current, PN pressure, contact pressure and supply can be changed during operation.
- the setting takes place via the current consumption or via the force value at the force sensor and no longer via the PN pressure, especially as this does not accurately represent the peeling pressure.
- the idler roller 5 of the peeling rollers 5, 6 can be readjusted to adjust the roller wear, so that the roller wear can be detected at the same time, and e.g. the time of roll change over a maximum achieved Walzenandruckwert can be done and no longer on the measured displacement of the Loswalze. 5
- roller peeler 1 can then be completely driven with only one energy form, including the vibro feed 2 ⁇ / ibrorinne 3.
- Expensive pressure regulator and solenoid valve for pneumatic devices can be omitted.
- the spring support (spring 10) of the tension roller 8 is independent of the adjustment by a servomotor 11, a PN cylinder o. A. acting.
- the spring 10 only has to complete the difference of the required length compensation.
- the spring 10 for the tension roller 8 is supported on the rocker 9 and the fulcrum of the tension roller 8 is preferably located in the pivot point of the rocker 9 or in its vicinity on the rocker 9 or on the housing of the WalzenC ⁇ lers first
