  • a vane or impeller wheel driven by an indexing mechanism and equipped with a horizontal shaft, this impeller wheel serving as a portioning dosing device.
  • this impeller wheel serving as a portioning dosing device.
  • the present invention relates to a new and improved packing machine for the production, filling, and closing at all sides of sealed flat packages formed of a heat-sealable material and serves for the packaging of granulate and fibrous or foliated pourable materials.
  • the inventive packaging machine broadly is of the type comprising an infeed container, a quantity-dosing device as well as a sealing station for the formation of the packages from a continuous band, and further includes a cutting station for cutting the coherent band equipped with the sealing seams.
  • Packaging equipment is already known to the art which fulfills the aforementioned functions. Feeding of this equipment with the material to be packaged is undertaken from a filling container through the agency of a disk dosing device operating according to the volumetric principle and having a horizontally arranged dosing disk, with the dosing operation of this device being adjustable. Two sealing rolls draw off the package material from a supply roller, the material then traveling over a folding shoulder at that location being folded to possess a substantially V-shaped configuration.
  • the finished packages are severe by a rotating knife having a vertical axis of rotation, whereupon they fall onto a chute having a two exits and are thereafter automatically counted by a suitable counting mechanism.
  • Another, more specific object of the present invention relates to an improved packaging machine which considerably exceeds the inherent limitations which were otherwise present with such type of prior art equipment and, further, ensures for an extremely protective handling of the material to be filled.
  • Still a further significant object of the present invention relates to an improved packaging machine of the mentioned type which is relatively simple in construction, extremely reliable in operation, not readily subject to breakdown, provides for extensive protective handling of the material to be packaged, enables increased production speeds without damage to the material, affords a compact construction of equipment which results in saving of space, and wherein the operation of the machinery itself is not complicated and can be therefore serviced much more economically and quicker.
  • the inventive packaging machine of the aforementioned type is manifested by the features that the quantity-dosing device embodies at least one predosing mechanism and a continuously operating fine dosing mechanism, wherein a portion dosing mechanism is arranged after both the predosing mechanism and the fine-dosing mechanism.
  • the invention advantageously contemplates equipping the predosing mechanism with a pivotable vane or blade for adjusting the pour height of the material onto a fine-dosing impeller or wheel equipped with an infinitely variable drive mechanism.

  • the fine-dosing wheel 26 is snugly seated within'the housing 27 in order to maintain any possible material losses as small as can be. Further, this fine-dosing wheel 26 has a roughened surface extending along its peripheral region which improves the entrainment of the material to be filled. Roughening of this peripheral surface can be, for instance, effected by providing teeth which are conventional through the formation of serrations.
  • Fine-dosing Wheel or impeller 26 rotates, in this instance, in the direction of the arrow 28 and possesses a gate or closure 29 at the region of the infeed opening 25 in order to prevent losses of fillable material, this gate 29 being situated approximately diametrically opposite a further gate or closure 30.

Adjustment of this gap 37 only provides a coarse adjustment of the dosing of the material to e filled, whereas the fine dosing is undertaken by regulating the rotational speed of the fine-dosing wheel or impeller 26.
  • the predosing vane 35 and the fine-dosing wheel 26 there is provided the possibility of regulating extremely exactly the dosing of the fillable material with the most protective processing thereof.
  • cover member 38 can also advantageously be formed of transparent material, to thereby permit inspection and observation of the fine-dosing wheel 26 without necessitating removal of such cover member.
  • the impeller or vane wheel 40 Arranged at a small distance below the fine-dosing wheel 26 is the impeller or vane wheel 40 having a horizontal axle or shaft 45. Furthermore, the housing 41 enclosing the impeller wheel 40 possesses an opening 42 through which the fillable material arrives at the individual compartment or pockets 43 of the impeller wheel 40. Impeller wheel 40. Impeller wheel 40 is fixedly secured to the shaft 45 by a key 46 or equivalent structure. Further, this impeller wheel 40 is driven in the direction of the arrow 47 through the agency of a suitable indexing mechanism, for instance a Maltese cross or Geneva indexing mechanism, schematically shown at 101 in FIG. 2, and arranged in the housing 1.
  • a suitable indexing mechanism for instance a Maltese cross or Geneva indexing mechanism, schematically shown at 101 in FIG. 2, and arranged in the housing 1.
  • the impeller wheel 40 does not actually carry out any dosing function as such because of the previously arranged predosing mechanism 35 and the fine-dosing wheel 26. Rather, it performs the function of dividing the continuous stream of fillable material flowing from the fine-dosing wheel 26 into portions, and to empty the fillable material portions into infeed funnel 5. Depending upon the dosing of material which is regulated, the pockets or compartments 43 of the impeller wheel 40 are filled to a greater or lesser extent. The closing operation or the distribution of the stream of fillable material into portions therefore also occurs in an extremely protective manner.
