Definitions

• the invention relates to a device for slicing food products, such as ham, sausage, cheese and the like, with a rotatingly driven and / or planetary rotating cutting knife, the cutting plane of which is perpendicular to a product support surface of a product feed device, the end of the product support surface on the cutting knife part of a cutting edge is formed, which forms a cutting gap together with the cutting knife.
• Devices of this type which are usually also referred to as slicers and work at very high cutting speeds, require clean and flawless cuts even at these very high working speeds and in particular also more difficult to cut products.
• Influential on the cutting quality has, in particular the quality or accuracy of the formed between the bearing surface for the respectively fed product and the rotating both around its own axis as' also planetary rotating cutting blade cutting gap.
• the object of the present invention is to design a device of the type mentioned at the outset in such a way that deviations from the desired cutting gap which degrade the cutting quality are eliminated and thus an optimal and constant cutting gap is ensured regardless of the knife used and also regardless of the respective operating conditions can.
• this object is achieved in that the cutting edge part is slidably mounted perpendicular to the cutting plane and is elastically biased against a stop, and that the stop is positioned and the cutting edge part is designed such that the cutting edge part against the applied bias of the knife with each knife pass at least touched and in particular slightly deflected against the bias.
• the cutting edge part which forms the cutting gap together with the cutting knife, is minimally displaced from its basic position with each knife pass, the size of this displacement being in the range of a few tenths of a millimeter.
• the cutting edge part is equipped in the entry area of the cutting knife with at least one guide surface, which ensures that the cutting knife hits a slightly inclined surface section of the cutting edge part, whereby disturbing friction and undesired wear are practically eliminated.
• Fig. 1 shows schematically a product feed unit cooperating with a cutting knife in a partially sectioned side view
• FIG. 2 is a front view of the arrangement of FIG .. 1
• the product feed unit 1 arranged in a machine housing 10 comprises a product support surface 2, along which the product to be cut in each case is transported in the direction of the cutting gap formed between the knife 4 and the front end of the product support surface 2.
• the product support surface 2 has three receptacles arranged side by side for three products to be cut simultaneously, as shown in FIG. 2.
• the front end of the product support surface 2 - as shown in Fig. 1 - is formed by a cutting edge part 3, which is preferably made of a suitable plastic material.
• the cutting edge part 3 is mounted in the product feed device 1 so as to be displaceable perpendicular to the cutting plane or to the orbit of the cutting knife 4, for which purpose the product feed device 1 has suitable guides tion surfaces 7. 2 shows two flight circles 9 of different cutting knives 4, for example.
• the displaceability of the cutting edge part 3 in the direction of the cutting plane is limited by a stop 6, which ensures that the cutting edge part 3 can protrude a maximum of only a few tenths of a millimeter into the cutting path of the knife 4.
• the cutting edge part 3 is prestressed in the direction of the cutting plane, specifically by at least one spring element 5.
• the cutting edge part 3 is equipped with a slightly inclined guide surface 8 in the area of the knife entry.
• a slightly inclined, short guide surface 8 is sufficient, the uppermost point of which is set back, for example, by about 1 mm with respect to the end face of the cutting edge part, and which then changes into a vertical course.
• an actively controlled cutting edge part can also be provided according to a further embodiment of the invention.
• Such a cutting edge part is controlled as a function of the movement of the knife and, if appropriate, also as a function of knife characteristics.
• Actuators for the movement of the cutting edge part are, for example, piezoelectric elements or other actuating elements which ensure sufficiently rapid and short-term movements of the cutting edge part over short distances, for example in the millimeter range.
