Definitions
- the invention relates to a rubber roller peeler, in particular for peeling rice or the like. Grains, preferably for separating the raw shell.
- the invention further relates to a method for controlling such a rubber roller peeler, in particular for controlling the roller speed.
- Generic rubber roller peelers are e.g. B. from DE-C-2705334 and DE-C-2838518 known. These have a pair of rubber rollers with pneumatically adjustable contact pressure. The paddy rice is fed centrally into the roller gap. The rollers are overhung and easy to change.
- By means of a belt running around the drive roller both rollers (belt pulleys) and a compensating roller, a constant belt tension is achieved without tensioning until the rubber rollers wear out.
- the drive speed is constant so that the faster running roller is subject to higher wear.
- they In order to achieve uniform wear on both rollers, they have to be exchanged several times, which results in a high level of maintenance and downtimes. Due to the wear, the roller diameter decreases differently, so that the differential and peripheral speeds also change to the disadvantage of the peeling process.
- the invention is therefore based on the object of designing a generic rubber roller peeler in such a way that even wear of both rubber rollers of a pair of rollers is achieved, the feed device can thus be formed independently of the grinding gap and interim downtimes due to roller exchange are avoided.
- the object is achieved on the basis of the characterizing features of claim 1.
- the rubber rollers are driven by separate motors and can be operated and controlled independently of one another.
- Another object of the invention is to develop a method for controlling a rubber roller peeler.
- This object is achieved by drives, the speed of which is preferably adjustable, for. B. by frequency converter. At intervals, each rubber roller runs alternately faster or slower in order to achieve even wear on both rubber rollers of the pair of rollers. The previous assignment of rollers (driven and entrained rollers, among others) is thus effectively canceled.
- the speed of the rubber rollers can be adjusted to different diameters in order to achieve the optimum peripheral and differential speeds for a peeling process.
- the roller or grinding gap is therefore independent of the accuracy of the grinding material feed, the grinding gap remains almost constant in its position, so that a tracking of the feed device or the like. is not necessary, but with high accuracy of the feed.
- the invention is described in more detail in an exemplary embodiment with reference to a drawing.
- the drawing shows the rubber roller peeler according to the invention in a schematic form.
- a rubber roller peeler has a frame and housing assembly 1, with a feed device 2, a pair of movable rubber rollers 3, 4 and a product outlet 5.
- the rubber rollers 3, 4 are provided with an engagement and disengagement device 6.
- the contact pressure of the rubber rollers 3, 4 is pneumatically controllable, the rollers 3, 4 are overhung.
- Each rubber roller 3, 4 is assigned a motor 7, 8, the motors being mounted in the frame and housing assembly 1.
- the power transmission takes place by means of toothed belts 9 on pulleys 10, 11 of the rubber rollers 3, 4.
- a direct drive of the rollers 3, 4 without a belt drive is also possible.
- Each motor 7, 8 has a frequency converter for stepless speed control.
- the engagement and disengagement device 6 acts on both rubber rollers 3, 4 together. It is also used for column adjustment, if necessary in conjunction with a separate fine adjustment. Separate, synchronously acting engagement and disengagement devices would also be possible.
- the speed control can also be carried out by means of an infinitely variable belt drive, but then the automation advantage that the frequency converter offers does not apply.
- the cereals to be peeled here rice, are already largely supplied to the roller nip 13 via a metering element 12 of the feed device 2.
- the peeled rice leaves the rubber roller peeler through the product outlet 5, together with the peeled peels, which are separated in a known manner in the further course.
