Definitions
- the invention relates to a product feed control of a roller mill, in particular a milling roller mill with an electrical sensor, a product feed device with adjustable drive means for the feed, and a method for controlling such a roller mill.
- the invention is therefore based on the object of eliminating the disadvantages described and of enabling a structurally simple product entry in the inlet, and which can be easily integrated into an automatic food regulation.
- Another object of the invention is to develop a method for regulating a roller mill, in particular the product feed.
- the product feed control according to the invention is characterized in that the measurement signal is generated by means of only one sensor arranged at the inlet.
- a strain gauge is preferably used.
- a control signal is generated which controls the engagement and disengagement of the grinding rollers or basic settings of the product feed.
- the sensor learns due to the product flow proportional to the product quantity above, a static and, depending on the nature and flow properties (especially flow rate) of the product a dynamic force component.
- the main advantage of the solution according to the invention consists both in a technically simple product registration and in an unproblematic adaptation into existing food controls, e.g. B. according to EP-B-515596. Furthermore, there are no mechanically moved and contaminable parts.
- the switch-on switch-off point can be detected with just one sensor and the feed control can be carried out with the same signal received.
- Fig. 1 schematically the basic elements of grinding by means of a roller mill
- Fig. 2 the arrangement of the sensor at the inlet (product inlet)
- a roller mill 1 as is usually used in milling (e.g. according to EP-B-334919 or DE-C-2730166), contains, among other things, a feed cylinder 2 with a product feed space 3, which has a distribution roller 4 in the lower part such as has a feed roller 5, which can be brought into the same direction by a gear 6 and drive means 7.
- a sensor 8 is arranged on the feed cylinder 2, which is connected directly to a signal converter 9 or can also be assembled as a unit.
- a weight force F is transmitted as a signal to the signal converter 9 by means of the sensor 8.
- the weight force F itself acts on the rod 10 of the sensor 8.
- the sensor 8 measures this force and passes this information on to the signal converter 9, whereby strain gauges (strain gauges) can also be used on the rod 10.
- the signal converter 9 is connected directly or via a signal converter 14 to the feed device.
- the sensor 8, 10 can be arranged anywhere in the feed cylinder 2 or product feed area 3 in front of the distribution and feed roller 4, 5. In individual cases it is conceivable to arrange a second sensor 8, e.g. with very high demands on the food control and / or complicated product flow conditions.
- the rod 10 of the sensor 8 is dust-proof and articulated in a wall of the product dining area 3.
- a feed gap 11 is formed by a segment 12, a segment adjustment device 13 being shown schematically.
- Two basic settings are possible, by starting from the signal of the sensor 8 and a signal converter 14 via dashed connections 15 or 15 ', either influencing the speed of the feed roller 5 or the position of the feed segment 12.
- the material discharged in the feed roller 5 is fed (arrow 16) to a pair of grinding rollers consisting of a fixed roller 18 and a loose roller 17.
- the loose roller 17 is assigned an engagement and disengagement device 19 which is controlled as a function of a control signal from the sensor 8 via a control line 20.
- the loose roller 17 is also assigned a grinding gap adjustment device 21 which can be adjusted by means of a handwheel 22 or by means of a motor 23 and an electronic storage computer unit 24. This depends on or as a function of specific grinding work, the quality of the regrind or the throughput of material through the roller mill 1.
- the actual food control takes place e.g. B. on the known from EP-B-38054 type of pneumatic or electrical adjustment of the feed segment 12 or the feed gap 11 or a speed control.
- the engagement and disengagement is controlled pneumatically or electrically.
