Definitions

• the invention relates to a device for slicing food products such as sausage, cheese, ham and the like, with a product feeder which feeds a product to be sliced to a cutting plane in which a cutting blade moves in a circulating manner adjacent to a cutting edge forming the end of the product feeder ,
• cutting devices which are also referred to as slicers
• food products of different consistency can be cut with high cutting sequence.
• the cutting devices must be able to carry out so-called idle cuts in which no slice is separated from the product.
• the product is briefly stopped or moved in the opposite direction to get safely out of reach of the cutting blade and so avoid unwanted chips.
• the product depending on its consistency and texture, tends more or less to "stick" with its front end to the product-carrying surfaces of this stationary section. A short-term reversal of the direction of the product required for the execution of blanks is thereby made more difficult or is only possible with insufficient accuracy. In addition, there may be a loosening of the product holder when it repeatedly performs retraction movements and this is counteracted by the "stuck" front end of the product.
• the object of the invention is to develop a device of the type mentioned in the simplest possible way such that disturbing adhesion and friction effects are eliminated as far as possible in the region of the product feed immediately upstream of the cutting plane.
• a termination region of the product delivery that encompasses the cutting edge is provided with means that stimulate vibrations at least one product-carrying contact surface and / or contact surface of the termination region.
• vibrations of the product-carrying surfaces lie in the ultrasound range.
• the use of other frequencies or sources of vibration is possible according to the invention depending on the particular circumstances.
• piezoelectric elements can be provided as vibration exciters.
• an oscillating mechanism for example driven electrically or pneumatically, which is used to generate vibrations of the product-conveying surfaces, e.g. includes rotating eccentric elements.
• the up and / or contact surface is formed on a separate, the cutting edge defining end piece of the product supply, which is coupled to at least one vibration source, the piece from the final piece as a whole in vibration.
• the end piece is preferably formed rectangular and in particular cuboid.
• the end piece may also be designed in the manner of a molded shell completely or partially enclosing the product to be sliced.
• the termination region is formed by two separate end pieces whose product-guiding surfaces and cutting edges are arranged at a particular right angle to each other and which are each set in vibration by exactly one vibration source.
• the end pieces are preferably each formed cuboid or have a cuboid basic shape.
• Fig. 1 shows schematically a plan view of a cutting device according to an embodiment of the invention
• FIG. 2 is a side view of the cutting device of FIG. 1.
• FIG. 2 is a side view of the cutting device of FIG. 1.
• the product feeder comprises an endless conveyor 29 on which a product to be sliced (not shown) rests and which feeds the product in the direction of the arrow to a cutting plane 11 in which an unillustrated cutting blade moves to slices from the front product end in a high cutting sequence Separate predetermined thickness.
• a driven endless conveyor belt for example, a free-running conveyor belt or a roller conveyor may be provided on which the product rests and is advanced in the direction of the cutting plane 11 with a product holder engaging eg in the rear product end.
• the conveyor 29 terminates at a distance in front of the cutting plane 11, which is for example 20 mm.
• a stationary horizontal end piece 17 is arranged, which reaches up to the cutting plane 11 and immediately adjacent to the cutting plane 11 defines a horizontal cutting edge 13, which cooperates in the cutting operation as a counter-blade with the cutting blade.
• the provided as a separate component end piece 17 is of cuboid shape.
• a lying substantially at the same height as the conveyor 29 horizontal bearing surface 25 of the horizontal end piece 17 forms the horizontal completion of the product feed.
• the horizontal end piece 17 is coupled on its underside with a vibration source 21, which is designed in particular as an ultrasonic source.
• a vibration source 21 which is designed in particular as an ultrasonic source.
• the ultrasonic generator 21 is positioned centrally with respect to the width of the product feed.
• the product feeder also comprises a lateral or vertical end piece 19, which also extends to the cutting plane 11 and defines a vertical cutting edge 15 which defines together with the horizontal cutting edge 13 a parallel to the cutting plane 11 extending cutting edge plane.
• the separate, also cuboid vertical end piece 19 provides a vertical bearing surface 27 for the front product end ready, which extends in this embodiment over a greater distance in the product conveying direction than the horizontal support surface 25 and, for example, has a length of 40 mm.
• the vertical end piece 19 is coupled on its rear side with a vibration exciter 23, which is of the same type as the vibration source 21 for the horizontal support surface 25 and in particular with this identical.
• the double arrows in FIGS. 1 and 2 indicate that the vibration exciters 21, 23 are oriented and oriented relative to the end pieces 17, 19 to be vibrated so that the main vibration direction is perpendicular to the bearing surface 25 or contact surface 27.
• the horizontal support surface 25 thus oscillates in the vertical direction, while the vertical contact surface 27 oscillates in the horizontal direction.
• FIGS. 1 and 2 The exemplary embodiment of the invention illustrated in FIGS. 1 and 2 is therefore distinguished by the fact that two product guide blocks 17, 19 extending at right angles to each other extend at right angles to each other for the front product end of a product to be sliced be provided, in each case with exactly one vibration generator 21, 23 are provided and can be excited with this as a whole to vibrations which are oriented at least predominantly perpendicular to these product-carrying surfaces 25, 27.
• the coupling of the vibration generators 21, 23 on outer sides of the final pieces 17, 19 according to the embodiment shown in FIGS. 1 and 2 is not the only way.
• the generators 21, 23 can also be integrated into the end pieces 17, 19. LIST OF REFERENCE NUMBERS
