Definitions

  • the invention relates to a cutting machine with which bread, meat, sausage, cheese and the like food can be cut into any desired thick slices.
  • T2 From the DE 694 10 502 T2 is a bread slicer with variable slicing thickness known.
  • the loaf of bread to be sliced is advanced by a slider step by step and fed to a rotating or oscillating cutting blade.
  • the existing in the form of a cutting blade cutting knife is driven by a motor.
  • the cutting means of such a disc-like circular blade which is equipped with its own rotary drive.
  • the circular blade is mounted on a swing arm swinging back and forth.
  • the food to be cut is passed gradually past the cutting means.
  • a cutting device is known, with a support consisting of a flexible band. This edition need not be longer than the product to be cut.
  • a cutting means is mounted on a carriage and moved along the table. In this case, the cutting means immersed in a cutting slot, which is formed by a system of deflection rollers for deflecting the flexible band and thus can move synchronously to the cutting means.
  • the present invention seeks to provide an improved fully functional cutting machine of the type mentioned.
  • the cutting machine according to the invention is characterized in that not the food, but the cutting means is gradually adjusted during the cutting process.
  • the cutting table on which the food rests, is also moved synchronously. Since the cutting means must completely pass through the bread when cutting the bread, for example, the groove-like or slot-like depression in the feed direction in the region of the cutting plane below the food must also be present be moved stepwise to prevent that during the advancing movement of the cutting means the same cut into the table surface and thereby could hurt the table surface.
  • the table is not moved according to the Querverschubs of the cutting means, but it is only one between the table and the food placed, a longitudinal groove or a longitudinal slot having bar along.
  • This food support shelf has the required groove or slot in which the cutting means can dip when cutting the bread. Details of the two variants are given in the claims further specified features and the embodiments.
  • the transverse displacement of the cutting means has the advantage that the longitudinal extent of the cutting machine in the feed direction of the food needs to be substantially smaller than twice the length of the food.
  • a cutting machine for example, for cutting bread with a longitudinal extent of almost 60 cm, so that such a cutting machine fits into the 60 cm grid of a shelf wall.
  • a driver for the cutting means may be present so that in each position of the cutting means, the cutting means remains firmly connected to the table. This carrier device thus ensures a mechanical coupling of the cutting means to the cutting table.
  • the cutting means may then be mounted on a pivoting frame, which by means of a Pivoting device is pivotable about a pivot axis so that in a pivot end position, the cutting means is completely traversed across the food and that in the other pivoting end position, the cutting means is completely moved out of the food space occupied by the gauge. In the latter position, the food can then be either inserted into the cutting machine or removed from the same.
  • the respective pivoting device comprises a cantilever mounted on the frame and a rotary member having a cantilevered extension, which is motorized displaceable in rotation.
  • a hinge rod is also hinged at one end to the free cantilever arm of the frame and at its other end hinged to the extension of the rotary member.
  • the above-mentioned entrainment means may include a pawl mounted on the pivoting frame which always engages with structural parts of the table.
  • a band blade may be present.
  • the slicer for bread and the like uses the favorable properties of a band saw known per se in the art, for example in the field of woodworking.
  • the cutting means present as a band knife or circular blade and the cutting table on which the food to be cut rests are pivotable relative to each other.
  • FIG. 13 Another embodiment of a cutting machine shows the exemplary use of a circular blade. Also in this embodiment, the circular blade is moved along the resting loaf of bread intermittently. Within one movement cycle, one slice of the loaf of bread is cut, i. a corresponding cut carried out. Further details of such a cutting machine can be found in the dependent claims 13 and following and one of the embodiments.
  • a cutter 10 for bread in particular, has a housing 14 which can be moved on rollers 12.
  • a pivoting frame 16 In its interior, a pivoting frame 16 is pivotably mounted about a pivot axis 18 within an angular range of-in the present example-about 45 ° (degrees). The lower pivot end position of the pivoting frame 16 is drawn through. The upper pivot end position is indicated in phantom by the reference numeral 16a in FIG.
  • the pivoting frame 16 has an approximately rectangular base frame, in whose three corner regions in each case a deflection roller 20, 22, 26 and additionally two further deflection rollers 24, 25 are mounted. Around the five deflection rollers, a band blade 28 runs around endlessly (FIG. 2).
  • a cantilever 30 is attached on the underside of the pivoting frame 16.
  • a hinge rod 32 is pivotally connected at its one end to the cantilever 30 to form a joint 34. With its other end of the hinge rod 32 is hinged to form a further joint 36 on an extension 38 connected.
  • This extension 38 projects from a rotary part 40, which can be set in rotation by means of a motor drive 42.
  • a first motor drive 46 acts via a rotary shaft 48 on the drive of the band blade 28 and in this regard on one of the deflection rollers - in the present case on the deflection roller 26 - a.
  • the other motor drive 50 is used for the stepwise advancement of an existing on the pivot frame 16 cutting table 60 in the feed direction 54 and in the present case in the opposite rearward movement 56.
  • the cutting means - in this case, the two pulleys 24, 25th with the Bandmesserabrough 28.1 - gradually moved.
  • Disposed on the cutting table 60 is a loaf of bread 62 to be cut. During its cutting, the loaf 62 rests against a holding plate 58 to allow the cutting table 60 to slip underneath the loaf 62; namely, the loaf 62 must not move with the cutting table 60.
  • the pivot frame 16 is pivoted from the raised position 16a in its illustrated in Fig. 1 lower position 16 down.
  • the band knife 28 is mitverschwenkt together with the frame 16 and.
  • the frame 16 is pivoted together with the band blade 28 upwards in the position 16a.
  • the pulleys 24, 25 and the cutting table 60 are in turn moved by one step in the feed direction 54.
  • the loaf 62 does not move with it.
  • the cutting table 60 may be slightly inclined to the horizontal. At the back of the table 60 may be present a side system, which forms an angle of 90 ° (degrees) in the present example with the table surface. Due to the inclined, slightly tilted back into the machine 10 in the arrangement of the cutting table 60 can be achieved that the loaf of bread 62 is immovably in a kind of lateral funnel. If necessary, then could be dispensed with the arrangement of the holding plate 58.
  • the stepwise movable cutting table 60 and coupled to the cutting table 60 cutting means are driven by the motor drive 50.
  • the cutting table 60 is in the form of a link belt 78 with each other endlessly hanging lamellar links formed.
  • a tensioning device 84 installed in the link belt 78 provides the required tension in the link belt 78.
  • This cutting groove 86 extends in the longitudinal direction of the slats and thus parallel to the guide shafts 80, 82 of the link belt 78 across the cutting table 60 away.
  • the band portion 28.1 of the band blade 28 is positioned above the cutting groove 86.
  • the band knife 28 passes over the four deflection rollers 20, 22, 24, 26 and in addition via the deflection roller 25 which is present between the deflection rollers 24, 26.
  • the deflection rollers 24, 25 limit the saw band section 28.1.
  • the two Umlenkroll'en 24, 25 are mounted on a respective carriage 88, 90 parallel to each other in the directions 54, 56 movable.
  • the guide roller 25 dash-dotted lines indicated intermediate layers 25a, 25b and the other feed roller 24 corresponding layers 24a, 24b occupy.
  • the mutual alignment of the pulleys 24, 25 is such that the band portion 28.1 is always perpendicular to the directions 54, 56 is present.
  • the movement of the rollers 24, 25 takes place synchronously with the movement of the link belt 78. In this way, above the cutting groove 86, the band blade section 28.1 is always positioned.
  • the band blade 28 has a width 96 (FIG. 2) which is substantially narrower than the thickness 97 of a conventional loaf 62, a dividing wall 98 is fixedly attached to the pivot frame 16 in alignment with the band blade portion 28.1. The cutting plane within the loaf 62 is thus filled by a part of the partition wall 98 and the band blade section 28.1.
  • the length dimension 100 of the cutting machine 10 therefore need not be greater than about 1.2 to 1.5 times the length 102 of the loaf 62.
  • a cantilever pawl 106 is attached (Fig. 1).
  • This pawl 106 is always in engagement with a cam groove 108 which is fixedly attached to the cutting table 60. Also in the dash-dotted line position 16a, the pawl 106 is engaged with the cam groove 108. In this way it is ensured that the cutting means and the table or the cutting groove can only be moved together in the feed direction 54 or in the opposite direction 56 (backward movement) ,
  • the cutting machine 10.3 shown in Fig. 3 differs from the cutting machine 10 only in that their cutting table 60.3 does not consist of a link belt, but that it is stationary in the machine. Moving is not the cutting table 60.3, as is the case with the cutting table 60, but instead a cutting groove pad 112 which is positioned between a loaf 62 and the cutting table 60.3 so that the actual groove 114 of this pad 112 with the Band section 28.1 of a band blade 28 is always aligned.
  • the cutting groove support 112 is held laterally on a carriage 116 for this purpose.
  • the carriage 116 is guided parallel to the adjustment direction 54, 56 of the two deflection rollers 24, 25 and driven at a comparable speed.
  • the cutting machine 10.4 shown in FIGS. 4 and 5 is not the food such as the loaf 62, but the cutting means, here a circular blade 118, during the cutting process gradually (intermittently) adjusted.
  • the circular blade 118 is arranged along one - in the present case linear - guide track 122 in both directions of movement of the same adjustable. Along this guideway 122 and a carriage 120 is movable in both directions of movement. The adjustment direction and the adjustment variable of the circular blade 118 correspond to the respective adjustment direction and the adjustment variable of the carriage 120.
  • the guideway 122 is inclined to the horizontal, so that a U-shaped receptacle 124, within which a loaf of bread 62 can be sliced by means of the circular blade 118, inclined or tilted to the front 126 of the housing 14.4 of the cutting machine 10.4.
  • the depth 128 of the housing 14.4 can be kept desirably small.
  • the carriage 120 is adjusted by a motor drive 129 along the guide track 122 back and forth.
  • the carriage 120 has on the output side a deflection roller 130 and two offset laterally and above the same arranged pulleys 132 and 134.
  • a toothed belt 136 is guided around. The two ends of this toothed belt 136 are fixed immovably at the points 138, 140 relative to the carriage 120.
  • a pivot rod 32.4 is rotatably mounted in a hinge 142.
  • the other end of this joint rod 32.4 is rotatably mounted on a projection 146 via a hinge 144.
  • the extension 146 protrudes from a rotary part 148, which can be rotated by the motor drive 129 in rotation 150.
  • the geometry of the components between the carriage 120 and the motor drive 129 is such that upon a complete rotation of the rotary member 148, the carriage 120 passes completely through the entire guide track 122 in one direction and completely in the opposite direction. As a result, the circular blade 118 is moved back and forth between its two end positions 118.1 and 118.2 (shown here).
  • Various positions of the rotary member 148 with its extension 146 and the hinge rod 32.4 and the carriage 120 are indicated by dash-dotted lines.
  • the guide roller 130 rotates along the toothed belt 136.
  • the guide roller 130 is rotated counterclockwise along the toothed belt 136. Accordingly, the circular blade 118 is driven counterclockwise 118.3. In this direction of movement, which represents the cutting direction 152, the circular blade 118 is passed through the loaf of bread 62 and the latter thereby cut.
  • the circular blade 118 During the movement of the circular blade 118 in the opposite direction 154, ie at the movement of the circular blade 118 in the direction of its right end position 118.2, the circular blade 118 would be driven clockwise according to the corresponding rotational movement of the guide roller 130 also in a clockwise direction, if not between the guide roller 130 and the circular blade 118 a not shown in the drawing freewheel would be installed. As a result, the circular blade 118 is driven rotatably only during its movement in the cutting direction 152.
  • the above-described construction parts of the cutting machine 10.4 for transversing the circular blade 118 in the cutting direction 152 and in the opposite direction 154 are fixed to a frame 156 which is perpendicular to the directions 152, 154, i. in the feed direction 54 and in the opposite direction 56 (backward movement) can be moved.
