Definitions

  • the invention relates to a dividing apparatus for dosin a plastically deformable mass, in particular dough, in equal quantities comprising a supply tank, a collection chamber with first piston and a closing device movable therein, a dividing chamber placeable in the line of the collection chamber and adjacent thereto and having a second piston movable therein fo successively drawing in mass out of the supply tank into the collection chamber, closing off the collection chamber from th supply tank, pressing mass out of the collection chamber into the dividing chamber, enclosing mass in the dividing chamber a transferring this mass therefrom onto a transporting device.
  • a dividing apparatus is known.
  • the collection chamber i a space of rectangular cross section under a supply hopper. Th collection chamber connects onto a dividing chamber likewise o rectangular cross section.
  • the pistons movable in the collecti and dividing chambers which hereinafter will be designated respectively as pressure piston and dividing piston, have a shape of rectangular cross section which fits into the relevan chamber and are usually manufactured from bronze.
  • a flat plate movable in lengthwise directio is situated between the top of the piston in the collection chamber and the upper wall of the collection chamber. This fla plate, also called knife, functions as closing device between the supply hopper and the collection chamber and also function as upper surface of the collection chamber along which the top surface of the rectangular cylinder can be moved.
  • Lubrication of moving parts in the dividing apparatus is an essential condition for the good operation thereof even when it is manufactured in accordance with the most stringent norms, but represents in practice a source of disturbances and delays ' , because, depending on the nature of the product, for instance dough, for processing in the apparatus, lubrication is subject to limitations. Cleaning of the known dividing machine is time-consuming. A high level of wear is inherent to the use of the materials applied in the machine and necessitates a periodic and costly overhaul.
  • the object of the invention is to provide a dividing apparatus not having these drawbacks.
  • the collection chamber comprises a cylinder-shaped first space
  • the closing device comprises a movable cylinder jacket fitting into this first space
  • the first piston comprises a movable cylinder-shaped part fitting into this cylinder jacket
  • the dividing chamber comprises a cylinder-shaped second space
  • the second piston comprises a cylinder-shaped part fitting into this second space.
  • the movable cylinder jacket functions as slide closing between the collection chamber and the supply hopper, while the inner surface of the cylinder jacket forms the surface along which the pressure cylinder is moved.
  • the cylinder-shaped collection and dividing chambers and the cylinder-shaped pistons offer the advantage that they can be manufactured by simple and thus inexpensive machining operations.
  • Another advantage compared to the known dividing apparatus is the better sealing between the pistons and the slide closing, for instance using piston rings received in peripheral grooves on one side and the parts along which these are movable on the other, whereby the chance of disturbance is smaller and it is possible to suffice with significantly less lubricant for the moving parts.
  • a machine according to the invention does not necessarily have to be assembled from relatively heavy components for good operation thereof, components other than those mentioned above, for instance the drive, can be manufactured more simply and inexpensively.
  • the costs of repair and/or overhaul of a machine according to the invention are considerably lower than those for a known machine because repair and overhaul are less often necessary and becaus it is for instance possible to refurbish the inner walls of the collection chamber and the dividing chamber by using a replaceable cylinder lining.
  • An apparatus according to the invention is particularly suitable for dosing equal quantities of dough, but can also be used for a great variety of other plastically deformable masses, for instance cheese curd.
  • the dividing chamber of a dividing apparatus is movable in operating conditions along a vertical guide between a first end position in which the dividing chamber is placed in the line of the collection chamber and a second end position in which the dividing chamber debouches above the transporting device.
  • the pistons in the collection and dividing chambers and the movable cylinder jacket, which functions as knife, are provided with a drive suc that the following successive steps can be performed.
  • the hopper filled for instance with dough is completely separated from the collection chamber by the knife, the pressing and dividing piston are pushed as fa as possible into respectively the collection and dividing chambers and the dividing chamber is not placed in line with th collection chamber but is situated at a level below the collection chamber.
  • a suction stroke first the knife and the the pressure piston are retracted, as a result of which dough i drawn out of the hopper into the collection chamber.
  • the knife is moved in a movement opposed to the preceding one, as a result of which the collection chamber is closed off again from the hopper and a separated quantity of dough is located in the collection chamber.
  • the knife now once again forms the peripheral surface of a cylinder-shaped chamber in which the pressure piston can b driven.
  • the dividing chamber an the dividing piston movable therein are placed in alignment wit and adjacent to the collection chamber.
  • the pressure piston is pressed in forward direction, as a resul of which the dough is pressed out of the collection chamber int the dividing chamber, wherein the dividing piston is pressed in rearward direction until it is stopped in an adjusted end position and the drive force exerted on the pressure piston has reached a determined preset value.
  • a measured quantity of dough which is pressed therefrom by the dividing piston to land on a transporting device.
  • the transporting devic normally ends at the entrance to a shaping machine, that is, a device in which the desired shape is given to the measured doug quantity.
  • the inner diameters of the movable cylinder jacket an of the cylinder-shaped second space are at least practically th same.
  • dough drawn into the collection chamber can be pressed into the dividing chamber in a manner wherein it is. subjected to minimum resistance.
  • At least one piston consists at least partly of plastic material.
  • a cylindrical plastic piston is simpler to make, is lighter, runs with less friction in an associated cylinder housing and is easier to drive than the corresponding rectangular bronze piston of the known dividing apparatus.
  • Plastic materials suitable for a piston are for instance high molecular polyethylene (HmPE), polyethylene (PE), polypropylene (PP) and polyamides (PA) .
  • a dividing apparatus is characterized by a driving of the movable cylinder jacket derived from the drive of the first cylinder.
  • Such a derived drive makes a direct driving of the movable cylinder jacket unnecessary, which results in a further simplification of the dividing apparatus and a further lowering of the purchase and operational costs thereof.
  • this latter dividing apparatus during forward movement of the first piston the movable cylinde jacket is coupled under spring tension to a piston rod of this piston.
  • the movable cylinder jacket coupled under spring tension is also moved in forward direction, that is, in the direction of the dividing chamber, until the cylinder jacket is stopped at the end of the separation stroke, whereupon the cylinder is pushed further in counter to an increasing spring pressure (the press stroke) .
  • the first piston is retracted until it i stopped against a fixed point on the movable cylinder jacket, for instance a rear surface, whereafter the movable cylinder jacket is likewise retracted and dough can be drawn out of the supply hopper into the collection chamber.
  • a dividing apparatus is preferably characterized by a driving of the first piston derived from the drive of the movable cylinder jacket.
  • Such an apparatus offers the advantage of a marked reduction in the volume required for the drives of the movable cylinder jacket and the first piston.
  • a piston rod for instance of the first piston is coupled under spring tension to this cylinder jacket.
  • the forward movement of the cylinder jacket (the separation stroke, wherein the supply hopper is closed off from the collection chamber) is followed with some time delay by the forward movement of the first cylinder.
  • the time delay occurs because in the coupling between the movable cylinder jacket and the first piston a pressure must first be built up that is sufficiently great to overcome the pressure of the dough mass present in the collection chamber.
  • the separation stroke and the press stroke transpose gradually as it were into one another.
  • the dividing apparatus is advantageously used when the transporting device comprises a conveyor belt disposed along a side wall, the carrying surface of which rises from this side wall at a determined angle in cross section perpendicularly of the transporting direction.
  • the shape of the measured quantities of dough ejected from the dividing chamber by the second piston onto the conveyor belt is of course determined by the shape of this dividing chamber. Depending on the shape of the dough quantities these must be further processed until a form suitable for baking is obtained.
  • a shaping machine is a prerequisite for shaping the dough, a shaping machine. It has now been found that with use of a dividing apparatus according to the invention a processing in a separate shaping machine can be omitted when the transporting device in the dividing apparatus has the above described feature.
  • the angle between the conveyor belt and the side wall in such a transporting device is adjustable.
  • An adjustable angle is for instance obtained with conveyor belt tiltable on a lengthwise axis or a side wall tiltable on a lengthwise axis.
  • figure 1 shows a cut away perspective view of a dividing apparatus according to the invention
  • figure 2 shows a schematic longitudinal section through part of another apparatus
  • figure 3 is a schematic longitudinal section through a part of yet another apparatus
  • figure 4 shows a schematic front view of a transporting device.
  • Figure 1 shows a dividing apparatus, for instance for dough, with supply hopper 1 above a cylindrical collection chamber 2 having a first piston 4 movable therein, designated hereinafter as pressure piston 4, and a movable cylinder jacket 3. Situated in the line of the cylindrical collection chamber 2 is a cylindrical dividing chamber 5 having therein a second piston 6 (dividing piston 6). In the ejecting position 51 the dividing chamber 6 is situated above a conveyor belt 7 which is fixed by rollers 9 in an adjustable roller support 8 along a concave side wall 10 which can be displaced relative to a side wall guide 12 using hand wheels 11. The apparatus is driven by drive shaft 13 which is provided with curve discs 14, 15, 16 connected to drive rods 18, 19, 26 respectively.
  • Two drive rods 18, 19 are connected to lever rods 20, 21 respectively which ar tiltable on a rocker shaft 17 and which are also connected via connecting shafts 22, 23 respectively to the piston rod 24 of pressure piston 4 and the jacket rod 25 of cylinder jacket 3.
  • Drive rod 26 is connected via a guide 52 connected to the frame to dividing chamber housing 27 and provides the downward movement of this housing in the direction of arrow 28.
  • Dividing piston 6 is received in dividing chamber 5 under bias which is exerted via piston rod 29, wheel 30 and guide 31 by springs 33 supporting on the frame. The spring pressure can be adjusted with adjusting screws 34 in the direction indicated by double arrow 35.

As a result of the rotation of drive shaft 13 piston 4 and cylinder jacket 3 are retracted, while dividing chamber 5 is driven downward as soon as drive rod 26 no longer co-acts with segment E of curve disc 16.
  • Figure 2 shows a schematic longitudinal section through part of another apparatus with supply hopper 201 above a cylindrical collection chamber 202 in which a movable piston 20 in a likewise movable cylinder jacket 203 is derived from the drive of pressure piston 204 by means of a spring 241 which is enclosed round piston rod 224 between a rear surface 238 of cylinder jacket 203 and a spring cup 239 connected to the pisto rod 224.
  • Spring cup 239 can be connected into piston rod 224 with different adjusting holes 240 so that the bias exerted by spring 241 on cylinder jacket 203 can be varied.
