Definitions

  • This invention concerns apparatusfor sectionali'zing or dividing materials into smaller discrete portions by a series ofy cutting operations.
  • the invention is susceptible of embodiment in 4a machine particularly well adapted forrcuttingvegetables, pitted or cored fruits, meats and the like, into slices, strips, cubes and 'flat-squares or rectangles.
  • One important object of the invention is the 20 provision of an' 'improvedl slicing constituent wherein the material to be slicedis propelled centrifugally about aY chamber wall icyclically lacross a wall opening .and against the cutting edge of a rotating disc knife Awhich slices; portions" from “the material :and facilitates their discharge outwardly through the wall opening.
  • Such :an arrange ment is fast in operation sin-ce the material can be fed into thechamb'er' without ypre-arrangement and also in View of the high speed With which the materialis propelled into -the slicing knife.
  • another object is the provision in s sectionalizing ⁇ cutting machine, of an improved'arrangenient Vwherebyfthe materialV in the'ou-rse of proc? essiiigis eaused te fon-ewa substantienystrelght 'th so the operating speed need not be limited by the necessity of changing the direction of ow for the material. This is accomplished by discharging the sliced material -onto a straight conveyor belt flight placed substantially parallel to the trajectory of the discharged slices and leading directly toa plane cutting block surface flush therewith and comprising an element of an assembly for cutting the slices into strips.
  • the arrangement is also such that the straight course lcontinues from the strip cutting assembly into an'assembly for cutting the strips into shorter pieces.
  • Straight line passage of the material through the machine between the cutting inf strumentality assemblies as well as within the assemblies themselves has been found to materially increase the speed attainable Without iinminence of misoperation and clogging.
  • Another object isthe provision in a strip-cutting assembly of a bank of disc knives having their cutting edges serrated to improve their cutting eiiiciency and to augment their tendency to pull the material which is to be cut into the assembly, This is an additional factor contribut ⁇ .x ing'to the high ope-rating speed of the machine embodiment herein described of the invention.
  • a further object is the provision of a cutting block surface with narrow grooves for receiving edge portions of the strip-cutting disc knives for cooperating therewith in completely severing the material into separate strips.
  • a further object is the provision of a new compressing roller structure with axially spaced circumferential ribs cooperable with thel belt 'i flight for compressing and feeding the sliced material into the strip-cutting assembly and said ribs being meshed with the strip-cutting knivesr toreduce the spacing therebetween
  • This feature has special utility when operating upon a matted layer of loose material such las spinach leaves and stalks.
  • Fig. 1 is a plan view of a machine constituting' a preferred embodiment of the invention

  • This pulley drives a belt 35 which is in driving relation with a pulley 36 rotatively fixed to the rear end of the shaft I2, A second pulley, 31, fixed.
  • the shaft 33 is driven by a belt 38 and a pulley 36 which rotates with the .motor armature shaft 4I.

  • Fig. 7 is a sectional view taken on the line IQ-1 ⁇ of Fig. 5.
  • the apparatus is adapted to operate upon large pieces of material such as those designated P, P and P in Fig. 3. These pieces of material may be any cuttable substancev such as fruit or vegetable articles or pieces of meat. Briefly, in
  • impeller blades direction of the arrow appearing just above said belt flight
  • the material, as fruit, vegetables and meat, operated upon is usually of a crushable nature and the feeding roller I 6 will be removed so as not to press against the slices.
  • contemplated for use most generally when the belt flight is loaded with a layer of compressible Roller assembly I6 is f bunchy material such as spinach or other leafy l material with stems and stalks and not necessarily issued from they slicing complement. Therefore, assuming the roller I6 to be absent, the belt night will slide the slices as S' onto the upper surface of a transfer plate I'I ⁇ which col operates with a bank of slicing knives I8' for cutting the Yslices into a series of strips ST.
  • Knives I9 cooperate with a cutting edge 2e of a stripper plate 23 in cuttingv the strips ST into ldice-like cubes CU.
  • the apparatus is mounted upon a plate 24, which is preferably the top of a bench or table, and receives driving force from an electric motor M suitably secured to said plate.
  • a standard 25 which supportsy the casing C.
  • a portion 25 of the casing wall I3 is hingedly connected at 2l to the remainder of the circular wall and is supported by means not shown in an adjustable manner whereby the distance of the lower or free end 28 of this wall portion radially of the circular wall from the edge of the slicing knife I5 may be selectively determined.
  • a bearing 29 projects axially from the rear wall of the casing to which it is secured. This bearing contains and provides a journal for the shaft I 2.
  • Bearing 29 is connected with the upper end of the standard 25.
  • the standard 25! in addition to supporting the bearing 29 and the casing C also supports a vertical bearing 3l, Figs. 3 and 4, and a horizontal ybearing 32, Fig. 1,
  • the wall I3 Adjacently to its edge 52 the wall I3 has'a beveled face 53 which adapts the upper i'lat face of the slicing knife to occupy the position of contiguity with the Wall edge 52.A It will also be observed that the vupper face of the slicing knife I5 continuesy as a plane surface al1 the Way to its circular cutting edge E while the lower fac-.l of this knife is beveled at 547 to lform the cutting edge. This arrangement minimizes any tendenc;7 for the knife to deect and disturb the position of the uncut portions. of j the'articles as P relaA tively to the circular wall I3', while. providing .clearance at the lower edge of lthe knife for the slices as S to ydischarge tangentially onto the ben flight F.

  • a further expedient employed for improving -the'ability' of the slicing discs lrto cut the strips ofmaterial into slices is the formation of serrated cutting-edges upon-thesediscsas illustrated.v in Figs. 5, 6 and 7; rOne'lside of each disc is provided with a pluralityof radial grooves 14S which intersect the sharpened-cutting edge 8I,-thereby providing vradially projecting sharpened vedge portions -82 -and radially receding sharpened edge portions 83 alternately withfthe portions 82.

This also necessitates re-l moval of the driving belts 36 and 38, but the time involved for effecting'such adaptation of the machine is normally insignificant when considering that many tons of material may be treated thereby before changing the adaptation.
  • the bulky material will be deposited on the belt iiight in a sufficiently thin stream or matted layer to pass between the roller and the belt iiight incident to being compressed into a relatively compact mass.
  • Positive traction of the roller with the material is enhanced by the peripheral apices 59, and 'downward deection of the belt flight beneath the roller is resisted by an idler roller R, Fig. 3.
