Definitions

  • the invention relates to cutting machines in which slices are to be cut from a strand-shaped or loaf-shaped material to be cut.
  • the material to be cut is often guided in a guide tube, with the portion of the material to be cut protruding from the front of the guide tube on the cutting side being cut off as a disc by a rotating knife, for example, directly on the cutting-side end face of the guide tube.
  • this guide tube can only consist of an axially very short so-called cutting goggle, which partially or completely surrounds that end of the material to be cut from which the slices are to be separated and the knife moves along its end face. In the following, however, only one guide tube is used throughout.
  • the present application also includes solutions in which a single knife of two or more loaves guided in adjacent guide tubes simultaneously separates one slice, and / or solutions in which the guide tube is part of one around its central axis rotatable guide tube turret, around which a plurality of guide tubes are arranged.
  • the knife should always cut through the material to be cut at the same, precisely defined axial distance, in particular the distance zero, to the end face of the guide tube, because this is the only way to produce slices with a defined thickness and thus also with a defined weight.
  • the rotating knife for example, is supported on the side of the guide tube by the guide tube itself, on the opposite side a support that requires axial installation space - be it due to the correspondingly large thickness of the knife itself or an additional support device there - is necessary, but disadvantageous because this makes it more difficult for the knife to penetrate the material to be cut.
  • an optimally thin knife would be the best solution, as it penetrates the material to be cut the easiest, but such a knife often does not have sufficient dimensional stability and, above all, insufficient positional stability, namely close to the end face of the guide tube.
  • the uneven cross-section of the meat loaf is expanded to the uniform cross-section of the guide tube, so that the material to be cut has a uniform cross-section in the form of a strand or caliber, but this also causes the material to be cut under a There is increased pressure and that outside the guide tube there should be a longitudinal stop for the end of the material to be sliced that is pushed out of the guide tube.
  • the knife Since the knife is not guided in a cutting gap on both sides, but only slides on one side along the end face of the guide tube, without additional measures there is a great risk that the knife will not be tight, in particular contacting, due to deformation, the irregular resistance of the material to be cut or other effects the end face of the guide tube slides along, but at a small distance therefrom, which undesirably changes the thickness and thus the weight of the disc produced.
  • edge of the pane is usually frayed, which is undesirable for optical reasons.
  • a grown piece of meat is surrounded by a so-called silver skin, a tendon-like material that is difficult to cut.
  • a clean cutting instead of tearing through this silver skin is only possible if the cutting edge of the knife rests against the end face of the guide turret or form turret, especially when the knife emerges from the material to be cut, i.e. the guide tube cross-section.
  • the knife In a cutting machine of the generic type , in which the knife is held on the end face of the guide tube by means of holding magnets, it is irrelevant whether the knife is a bar-shaped knife, a rotating circular disk-shaped knife or a rotating sickle-shaped knife or the knife of a band saw.
  • the holding magnet (s) are arranged in the penetration direction only near the exit side of the guide tube cross section and outside the guide tube cross section, and not near the entry side.
  • the direction of penetration is understood to mean the perpendicular to the knife edge which lies in the knife plane defined by the knife edge and / or the main plane of the knife. If the knife edge is curved, the perpendicular starts at the middle of the length of the knife edge.
  • the knife is only subjected to magnetic force in the last part of the passage section of its knife edge through the material to be cut, i.e. through the guide tube cross-section, in the direction of the end face of the guide tube and thereby usually also brought into contact with the end face.
  • this offers the advantage that before the magnetic force acts on the knife, i.e. in the first part of the passage of the cutting edge along the penetration path, there is no application of magnetic force to the knife in the direction of the end face of the guide tube and the knife does not or only the end face contacted with a very low contact force, so that there is hardly any heating of the knife and guide tube and hardly any increase in the cutting force to be applied.
  • the holding magnet or magnets are only arranged in the last third of the penetration path of the knife edge in the penetration direction.
  • the at least one holding magnet is arranged as close as possible to the outer circumference of the guide tube cross-section in order to apply magnetic force to the knife in the area of the guide tube cross-section in the direction of the end face.
  • the holding magnet is preferably arranged transversely to the penetration direction, i.e. in the radial direction of the guide tube cross section, closer than 30 mm, better closer than 20 mm, better closer than 10 mm to the circumference of the guide tube cross section.
  • the one or more holding magnets are arranged so close to the longitudinal position of the front, cutting-side face that the tensile force of the holding magnet on the knife at the longitudinal position of the cutting-side face still reaches or exceeds a predetermined minimum tensile force.
  • the longitudinal position of the holding magnet is preferably adjustable for this purpose.
  • the minimum tensile force of the individual magnets mounted in the machine at the longitudinal position of the cutting-side face should be at least between 100 N and 10 N, better between 70 N and 20 N, better between 50 N and 30 N, especially in relation to the knife used -Material.
  • the sum of the minimum tensile forces of all holding magnets present on a guide tube should be between 400 N and 40 N, better between 280 N and 160 N, better between 200 N and 120 N, especially compared to the knife material used. All holding magnets present on a guide tube should in particular be those holding magnets which, when a pane protruding from this guide gate is cut off, at most all of them act together on the cutting knife.
  • So-called knife steel is preferably used as the material for the knife, which is usually defined in such a way that its grade number starts with 1.40 - 1.46, preferably 1.40.
  • the nickel content should be a maximum of 2.5% by weight and the carbon content a maximum of 1.2% by weight, while the chromium content should be at least 10.5% by weight, better still 13-15% by weight. If molybdenum is contained, its proportion should not be higher than 1.0% by weight.
  • the counter number following in the type number is preferably between 16 and 34 and is preferably 21.
  • the subsequent last two digits of the type number for the steel production process and the treatment state are preferably 3 for the steel production process and / or 4 for the treatment state.
  • a steel of the grade number 1.4021.34 is therefore preferably used as the knife steel.
  • the steel used for the knife must of course be able to be acted upon by magnetic force, i.e. it must be a soft magnetic material.
  • the knife is preferably positioned with respect to the end face of the guide tube in the axial direction in such a way that the one facing the guide tube On the side of the knife without application of magnetic force, a narrow cutting gap of no more than 0.5 mm, better no more than 0.3 mm, better no more than 0.2 mm to the guide tube.
  • the knife In order to pull the knife by means of the magnetic force of the at least one holding magnet until it makes contact with the end face - if the knife does not contact the end face without being applied by magnetic force - the knife should have a thickness of at most 10 mm, in particular at most 8 mm, in particular at most 6 mm, in particular have a maximum of 4 mm, in particular a maximum of 3 mm.
  • the knife should have an extension of at least 10 mm, in particular at least 30 mm, in particular at least 50 mm, in the penetration direction.
  • the extent from the cutting edge to the bearing block in which the knife is mounted is to be measured.
  • the knife consists of a soft magnetic material, that is, a material on which a force can be exerted by means of a magnet.
  • the knife is preferably made of stainless steel, that is to say a mostly high-alloy steel which does not rust under the conditions of use of such a cutting machine, but which at the same time has soft magnetic properties.
  • the knife is preferably a knife that is only sharpened on one side, the sharpened side preferably being on the side of the knife facing away from the guide tube. Therefore, regardless of the exact dimensions of the knife, that is, its regrinding state, no changes to the positioning of the magnets, in particular in the axial direction, have to be made.
  • the base frame of the cutting machine is stored.
  • the guide tube openings 1.1-1.5 are used to receive a loaf 100 to be cut into slices, which in the initial state has a has an elongated but irregular shape, so that, corresponding to the cross-section of the loaf 100 in the initial state, it can optionally be introduced into a guide tube opening 1.1-1.5 with the best cross-section from above, from the loading end 1b, which of course does not apply to this the cutting position 12 may be, since there the longitudinal press drive 6 prevents the insertion from above.
  • That angular position or angular segment with respect to the axis of rotation 1 'of the guide tube turret 1 which is swept over by the knife in use is referred to as the cutting position 12.
  • the cutting position 12 is the angular position at which the penetration direction 2 is located.
  • a rotating, circular disk-shaped knife 3 is arranged, which is driven to rotate around a knife axis 3 ', which is preferably parallel to the switching axis 1', the axis of rotation of the Guide tube turret 1 is located.
  • the rotating knife 3 can be moved back and forth in a 1st transverse direction 11.1 to the longitudinal direction 10, which corresponds to the direction of the indexing axis 1 'of the guide tube turret 1, radially to the guide tube opening in the cutting position 12, e.g. 1.1 to cut off slices 101 of the product to be cut 100.
  • the severed disc 101 falls onto the discharge conveyor 8 arranged below and is moved by this, for example, in the direction of view of the Figure 1c transported away.
  • FIG Figure 2c thus shows the state immediately before the severed disc 101 fell onto the discharge conveyor 8, while in FIG Figure 1c the disk 101 is already on the discharge conveyor 8.
  • the knife axis 3 ′ can also perform an arcuate, oscillating, or circular movement in order to cut off one disc 101 at a time.
  • a longitudinal pressing drive 6 is arranged above the guide tube turret 1 at the so-called cutting position 12, viewed in the direction of the indexing axis 1 'and lying within the circumference of the guide tube turret 1, on the base frame of the machine.
  • the longitudinal press drive 6 consists of a working cylinder, preferably a hydraulic cylinder, the piston rod of which can be moved in the longitudinal direction 10 6a when the working medium is applied from the lower, open end of the cylinder 6b increasingly extends and with its front end a longitudinal ram 4.1, which fits into the cross-section 1.1 'of the guide tube opening 1.1 below, pushes it into it until it rests on the loaf 100 and this presses down in the longitudinal direction 10 against a stop.
  • a working cylinder preferably a hydraulic cylinder
  • the stop serves as a stop Figure 1d Stop plate 14 that is moved up to the lower end face of the guide tube opening 1.1 located in the cutting position 12 and held, preferably completely covering this guide tube opening 1.1 before the start of the cutting process.
  • longitudinal press rams 4.1 - 4.5 are arranged in a circular manner around its axis of rotation 13 ', the cross sections of which correspond to one of the cross sections 1.1' - 1.5 'of the guide tube openings 1.1 - 1.5 and are thus arranged in the press ram turret 13 are that they fit exactly and preferably liquid-tight into one of the guide tube openings 1.1-1.5 when they are in the cutting position 12 above this matching guide tube opening.
  • the ram turret 13 can be rotated about the likewise upright, parallel to the indexing axis 1 ', but offset in a transverse direction, the indexing axis 13' so that with a certain guide tube opening 1.1 at the cutting position the same cross section 4.1 ' having longitudinal ram 4.1 can be positioned over this guide tube opening 1.1 by rotating the press ram turret 13 accordingly.
  • the coupling parts 9a located on the upper side of the longitudinal ram 4.1-4.5 lie on a circular path around the switching axis 13 'of the press ram turret 13. If the corresponding longitudinal ram 4.1 is in alignment and above the cutting position 12, exactly in the path of movement of the another, complementary coupling part 9b arranged at the front end of the piston rod 6a.
  • the longitudinal press ram 4.1 moves against a ram stop 15 when it reaches the corresponding recess in the press ram turret 13 or in this recess, so that when the piston rod 6a is retracted further, the coupling 9 solves and automatically releases the corresponding longitudinal ram 4.1, which is now held again in the ram turret 13 in the recess provided for the longitudinal ram 4.1, for example magnetically or by suitable locking elements there.
  • Switching axis 1 means that the guide tube turret 1 can be rotated, but can also be locked in certain angular positions so that it is possible to switch from one to the next of the defined angular positions.
  • the 1st transverse direction 11.1 is always spoken of, without restricting the invention to this, although the direction of displacement 2 is also a different transverse to the longitudinal direction 10 of the guide tube turret 1 can be direction.
  • the knife 3 is mounted rotatably about its knife axis 3 ′ on a slide 19, which can be moved in this direction of displacement 2 with respect to the cutting base frame 18.
  • the stop plate 14 is also carried by the slide 19, but is adjustable with respect to it at least in the axial direction 10, possibly also in the radial direction.
  • knife 3 and stop plate 14 move preferably synchronously in penetration direction 2, preferably 1st transverse direction 11.1, so that the resulting disc 101 is increasingly pushed through the gap between cutting edge 3a of knife 3 and the functional edge 14a of stop plate 14 facing the knife .
  • the functional edge 14a is - in the axial direction 10, for example viewed from below - preferably concavely curved and runs in alignment or slightly radially outward in this viewing direction, in particular at a constant distance over the length of the functional edge, compared to the circular circumference of the cutting edge 3a .
  • the stop plate 14 and thus its functional edge 14a can additionally according to FIG Figure 1a can be adjusted in the 1st transverse direction 11.1 with respect to the carriage 19 and thus the cutting edge 3a of the knife 3, preferably also during the cutting process.
  • Figure 1d shows a state of the cutting machine in which two processes are shown at the same time, but in practice they do not have to occur simultaneously: On the one hand, the stop plate 14 is raised so far that it rests directly on the lower end face of the guide tube turret 1, the cutting end 1a, as may be necessary as a stop for the longitudinal pressing of the loaf 100 at the cutting position 12.
  • the knife 3 is shifted so far away from the indexing axis 1 'of the guide tube turret 1 that, viewed in the longitudinal direction 10, it is completely outside the cross section of the guide tube turret 1, so that the knife 3, which is on its underside from the slide 19 is supported, is freely accessible from the top over its entire surface and can be removed upwards after loosening a quick-release fastener 20 and exchanged for another knife.

  • Figure 4 shows - again viewed in the longitudinal direction 10, usually the longitudinal pressing direction - the arrangement of the holding magnets 7 with two guide tube openings 1.1, 1.2 running parallel next to one another, which additionally in a 1st transverse direction to the longitudinal direction 10 by means of a transverse pressing of the loaf inserted therein of a cross press ram. Since in this case the penetration direction 2 often coincides with the transverse compression direction, the length of the penetration path 2 ', which the knife edge 3a has to cover through the cross section of the guide tube opening, also changes with the extent of the transverse compression.
