Definitions
- the invention relates to a product feed control of a roller mill, in particular a mill roller mill, with an electrical sensor, a product feed device with adjustable drive means for feeding.
- Such a speed control is described, for example, in DE-U-8614505.
- EP-B-38054 a segment adjustment is described.
- the invention is therefore based on the object of eliminating the disadvantages described and enable a structurally simple product entry in the inlet, and which can be easily integrated into an automatic food regulation.
- the product feed control according to the invention is characterized in that the measurement signal is generated by means of only one rod-shaped sensor arranged at the inlet, which is arranged transversely or perpendicularly to the direction of flow of the product.
- a strain gauge is preferably used.
- a control signal is generated which controls the engagement and disengagement of the grinding product feed. Due to the product flow, the sensor experiences a static and, depending on the nature and flow properties, in particular the flow rate of the product, a dynamic force component proportional to the product quantity above.
- the main advantage of the solution according to the invention is both technical simple product registration as well as an unproblematic adaptation into existing ones Food regulations, e.g. B. according to EP-B-515596. Furthermore there are none mechanically moving and contaminable parts available.
- the switch-on / switch-off point can be detected with just one sensor and with With the same signal received, the feed control can take place.
- a roller mill 1 as is usually used in the milling industry (e.g. according to EP-B-334919 or DE-C-2730166) contains, inter alia, a feed cylinder 2 with a product feed area 3, which in the lower part a distribution roller 4 and a feed roller 5, which via a gear 6 and drive means 7 in circular movement can be brought in the same direction.
- a sensor 8 is arranged on the feed cylinder 2, which is connected directly to a signal converter 9 is connected or can also be assembled as a unit.
- a weight F is transmitted as a signal to the signal converter 9.
- 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, also Strain gauges (DMS) can be used on or as rod 10.
- the signal converter 9 is connected directly or via a signal converter 14 to the feed device connected.
- the sensor 8, 10 can in principle at any point in the Feed cylinder 2 or product feed area 3 in front of distribution and feed roller 4, 5 be arranged. In individual cases it is conceivable to arrange a second sensor 8, e.g. with very high demands on the food regulation and / or complicated product flow conditions.
- the rod 10 of the sensor 8 is in a wall of the product feed area 3 dust-proof and articulated.
- a feed gap 11 is formed by a segment 12, with one schematically Segment adjustment device 13 is shown.
- Two basic settings are possible by starting from the signal of the sensor 8 and a signal converter 14 dashed lines 15 and 15 'either influence the speed of the feed roller 5 or on the position of the food segment 12 is taken.
- the material discharged in the feed roller 5 becomes one (arrow 16) Grinding roller pair, consisting of a fixed roller 18 and a loose roller 17 fed.
- the loose roller 17 is assigned an engagement and disengagement device 19, which depends controlled by a control signal from the sensor 8 via a control line 20 becomes.
- the loose roller 17 is also assigned a grinding gap adjustment device 21, which by handwheel 22 or via motor means 23 and an electronic memory computer unit 24 is adjustable. This depends on or as a function of specific grinding work, the grist quality or the throughput through the roller mill 1.
- the actual food control takes place e.g. B. on those known from EP-B-38054 Type of pneumatic or electrical adjustment of the food segment 12 or the feed gap 11 or a speed control.
- the indentation and indentation will pneumatically or electrically controlled.

Description
- eine gleichmässige Produktverteilung auf die ganze Länge der Mahlwalzen
- innerhalb zulässiger Toleranzen muss die jeweils dem Walzenstuhl zufliessende Produktmenge verarbeitet werden und Zuführschwankungen müssen möglichst ausgeglichen werden
- bei Unterbrechung der Produktzufuhr muss bei minimaler Verzögerung die Produktspeisung auf die Mahlwalzen gestoppt und gleichzeitig müssen die Mahlwalzen ausgerückt werden.
