- an LED 20 is provided which, for example, indicates a grinding phase (red) and a rest phase or a ground state (after the grinding phase) of the knife 2 (green).
- one or two cleaning brushes 22 or the like arranged on both sides for cleaning the knife 2 from grinding dust etc. and / or a holding element for the Knife backs are provided.
- an automatic, mechanical process can be used instead of a manual activity, i.e. sharpening the knife blade of a high-quality kitchen knife 2 by hand.
- the kitchen knife 2 used is inserted into a knife block 3 with an automatically running grinding unit 9.
- One or more advantageous sensors 6 recognize the inserted knife 2 and the automatic grinding system is carried out, for example, once, but preferably several times. This eliminates the tedious re-sharpening of kitchen knives 2 that have been stored for different periods of time.
- An automatic knife sharpening block 3 or a grinding unit 9 is advantageously provided for each knife 2.
- a basic knife block 3 or so-called “master” with a power supply 16 is preferably provided, to which all further knife blocks 3 or so-called “slaves” are electrically adapted / coupled.
- a knife 2 can be removed from any knife block 3 and put back again in order to advantageously initiate or carry out an at least one-time grinding process at this sharpening station or knife magazine 4.
- Frequently used knives 2 are thus always usable and sharp according to the invention; as well as the rarely used knives.
- a positive side effect here is the order in the kitchen or in the entire or modular knife storage unit 1 and always sharp knives 2.
- the fourth variant according to the Figures 6, 7 has a transport carriage 13, the two, each with Cutting elements 24 or ceramic rods 24 which are acted upon by springs 25 or are adjustably mounted along an adjustment direction 32 and are preferably releasably fixed to a lever mechanism or lever 28, in particular by means of screws or the like, in order to be replaced if necessary or when worn.
- the transport slide 13 can be moved up and down on a toothed rack 14 or guide rail 14 or the like with a motor 12.
- the grinding elements 24 are mounted on a lever mechanism with several axes of rotation 33, 34, 35 and can be adjusted transversely to the transport path 11 by means of the springs 25.
- the adaptation to the curved blade contour takes place here or can generally also be advantageously implemented in other variants in such a way that the adjustable or resilient transverse adjustment and an angular arrangement of the grinding elements generate a contact force and thereby the cutting element 24 is pressed against the cutting edge.
- differently curved / curved edges can also be traversed or "followed”.
- a pivotable mounting of the rack 14 or guide rail 14 can thereby be omitted.
- An advantageous mode of operation of the automatically sharpening knife block is, for example: The knife 2 is inserted into the knife block 1, 3 for storage.
- the internal sensor 6 e.g. reflective light barrier
- the internal sensor 6 in the end of the knife block detects the inserted knife 2.
- a motor-operated transport slide 13 moves up and down along the knife edge contour or the transport path 11 as soon as the sensor 6 has recognized the inserted knife blade 10 of the knife 2.
- the grindstones 24 are pressed / pressed against the blade 10 during the grinding process and are spaced or removed from the blade 10 by means of the adjusting device 31 in freewheeling or reverse motion, so that the blade 10 is not grinded / pulled off in freewheeling mode, ie no material is removed or removed no chip formation is realized.
- a rotating and spring-loaded grinding wheel 10 moves in a likewise resiliently mounted rocker arm or the toothed rack 14 along the blade.
- the spring-mounted rocker arm with the grindstones 24 and the adjusting device 31 sit together on an advantageous drive motor support or transport slide 13.
- the drive motor 12 with pinion 15 and drive motor carrier transports the grinding unit 9 along a rack 14.
- the toothed rack contour is similar to the contour of the knife blade, so that the grinding stones 24 always grind along the blade with the same spring force as possible, which leads to a uniform grind.
- the toothed rack 14 has, for example, a shape that determines the sliding path curve.
