Definitions

  • the invention relates to a device for slicing food products, in particular high-performance slicers. Furthermore, the invention relates to a system with such a slicing device and with at least two differently shaped cutting blade carriers, which are each releasably attachable to a rotor shaft.
  • Such slicing devices are basically known and serve to slice food products such as sausage, meat and cheese into slices at high speed. Typical cutting speeds are between several hundred to several thousand cuts per minute.
  • Modern high-performance slicers differ, inter alia, in the design of the cutting blade and in the manner of the rotary drive for the cutting blade. So-called sickle or spiral cutters merely rotate around a knife axis, whereby this knife axis itself does not perform any additional movement.
  • the circular blade rotating about a knife axis circulate in a planetary manner in addition to this self-rotation about a further axis spaced apart from the knife axis-here called a rotation axis.
  • Which blade type or type of drive is to be preferred depends on the respective application.
  • the invention relates to slicing with a planetary rotating circular blade.
  • Typical cutting speeds are in the range of about 350 to 800 revolutions per minute, ie with such a slicer about 350 to 800 discs per minute can be separated from a product.
  • the circular blade containing cutting head has a relatively complex structure and is axially adjustable as a whole.
  • the cutting head has a non-rotatable axis, wherein about this rotationally fixed axis of a rotational drive rotationally driven hub, which simultaneously represents the blade holder, can be rotated.
  • This known circular knife slicer discloses a general basic problem, which in principle precludes a tactile design of a circular blade slicer, namely the requirement not only to circulate the circular blade planetary, but also to provide a self-rotation. Consequently, the circular blade not only has to be driven in a planetary orbit, but also has to be set in rotation around its own knife axis. This results in an already complex drive technology, which requires a much higher design effort, if in addition the circular blade should be adjusted quickly and precisely axially in order to perform idle cuts can.
  • Circular knife slicers are thus, in principle, significantly less time-critical in terms of axial adjustment. However, so far has hardly been trying to develop practical concepts for tactile circular knife slicer.
  • the object of the invention is to provide a slicing device, which is based on the principle of a planetary rotating circular knife and is capable of a blank cutting operation, which also should be given a simple, compact and hygienic design and in particular the full functionality of modern high-performance slicer ,

  • the invention is based on the idea, in departure from the above-explained concept according to WO 2008/034513 Al not to adjust the entire cutting head in the axial direction, but to axially displace a rotor shaft supporting the cutting blade via a rotor, ie to provide an axially adjustable rotor shaft.
  • This concept makes possible, surprisingly, a simple, almost minimalistic design of a tactile circular blade slicer, which is also compact, meets the highest hygiene requirements and, in particular, in certain specific embodiments, as explained in more detail below. despite omitting components of comparable performance on other high performance slicers - yet fulfilling a very high level of functionality.
  • the concept according to the invention also and indeed allows a concentration on an optimal axial adjustment of the knife, whereby important functions such as e.g. the cutting gap setting can be taken over, so that e.g. no axially adjustable cutting edge is needed. It is also not necessary to retract the product since the blade can be adjusted axially for a blank cutting operation. Finally, for this reason, even expensive tractors or conveyor belts for the product can be omitted.
  • a peculiarity of the invention is that a circular-slicer, which actually requires no Messeraxialver ein due to the cutting speed, is nevertheless optimized in terms of Messeraxialvergna, since it was recognized that in a clever basic design and a circular knife slicer with a fast and reliably functioning axial adjustment are provided for the knife and this axial adjustment can also take over essential functions, which in turn otherwise necessary components can be omitted, which - and so closes the circle - the optimization of the axial adjustment at least relieved.

  • the axle 39 or shaft 40 extends through the hollow shaft 13 and into the rotor 15.
  • the axle 39 carries a toothed belt wheel 41, which is also fixed with respect to rotation and on which, when the rotor 15 rotates, a toothed belt 43 rolls, which cooperates with a toothing 45 which is formed on the blade shaft 35 carrying the circular blade 17.
  • the planetary orbital motion of the blade shaft 35 due to the rotational movement of the rotor 15 relative to the fixed toothed belt wheel 41 is thus used to set the blade shaft 35 and thus the circular blade 17 in rotation about the blade axis 19 relative to the rotor 15.
  • the rotor 15 is formed in two parts. This also applies to the embodiment of FIG. 9.
  • the hub 23, including the combined axial and rotary bearing 21 for the rotor shaft 13 designed as a hollow shaft, is located within a housing, ie is not open to the outside.
  • the hub 23 is fixed to a wall 31 of the housing.
  • the rotor shaft 13 is provided with a Anlenkabêt 65 for a turn again only indicated axial drive 71, which serves to axially adjust the rotor shaft 13 together with the rotor 15 and circular blade 17. This is again indicated by double arrows.
  • the fixed axis 39 is not axially adjustable as a whole, but telescopically formed, so that the toothed belt 41 bearing front portion of the shaft 39 can be adjusted axially together with the rotor shaft 13, in particular to carry out idle cuts or make a cutting gap setting.
  • the hub 23 is formed by a fixed housing wall 31, wherein alternatively the hub 23 may be formed as a separate component which is fixed to the housing wall 31.
  • the drive shaft 40 extending through the rotor shaft 13 designed as a hollow shaft is provided with a toothed belt wheel 67 at its rear end and can be set in rotation by means of a toothed belt 69 by a separate drive motor, not shown, independently of the rotary drive 33 for the rotor shaft 13.
  • the transmission of the rotational movement of the drive shaft 40 to the blade shaft 35 takes place within the rotor 15 via a toothed belt 43 which cooperates with a toothing 45 of the cutter shaft 35 and with a toothed belt wheel 41 of the drive shaft 40.
  • a common drive motor be provided with intermediate gear, whereby the belts 53 and 69 are driven.
  • a common axial adjustment of the rotor shaft 13 and the drive shaft 40 is effected by an axial drive 71, again not shown, which acts on an articulation section 65 of the rotor shaft 13.
  • the balancing concept explained above in the introductory part and in connection with the embodiment of FIGS. 1 to 7 is also realized in the embodiments according to FIGS. 8 and 9:
  • the rotor 15 is in each case provided with a first balancing mass 47, while a second balancing mass 49 each integrated into the drive pulley 51 of the rotary drive 33 for the here designed as a hollow shaft rotor shaft 13.
  • the belt drives for the rotor shafts 15 and for the drive shaft 40 of the axial adjustment does not oppose, since in this case only relatively short axial travel are required and consequently the drive belt 53, 69 can be deflected accordingly.

Abstract

L'invention concerne un dispositif pour découper en tranches des produits alimentaires, en particulier un trancheur à haute performance, comprenant un arbre de rotor axialement déplaçable, tournant en service autour d'un axe de rotation, en particulier pour effectuer des coupes à vide et/ou pour régler la fente de coupe, un rotor entraîné par l'arbre de rotor, une lame portée par le rotor, en particulier une lame circulaire, qui tourne de manière planétaire autour de l'axe de rotation et tourne en outre autour d'un axe de lame s'étendant parallèlement décalé de l'axe de rotation par rapport au rotor, et un entraînement rotatif pour l'arbre de rotor.
