Definitions

  • the invention relates to an apparatus having a conveying means and supporting means for supporting an object to be shaped, for instance a filled bag, and two shaping means consisting of two driven guide belts, one at each side of the conveying and the supporting means, which belts have a converging portion adapted to shape an object supported by the conveying and supporting means and a means for discharging the object in a direction transverse to the direction of movement of the guide belts.
  • Such an apparatus is known from GB-A-1 054 738.
  • this known apparatus the object does not engage the guide belts when it is discharged by pushing it away with a pushing member. This way of handling may in many instances detoriate in a greater of lesser degree the shape of the object shaped by the guiding belts.Further this known device does not provide a means for filling the object into a box or container without antibiotic to loose its shape.
  • the invention aims to provide a simple apparatus which elimi­nates the above disadvantages, at least to a major extent.
  • the means for discharging the shaped object consists of a removable portion of the support means, which removable portion of the supporting means is located between the guide belts, which at that location are adapted to engage the object to take it along on said removable portion of the supporting means.
  • NL-A-7004838 shows a device for shaping objects by means of guide belts having a converging part.
  • the shaping of the object is here, however, secondary and the main purpose is to flatten, label or close the filling aperture of the bags, forming the objects. Further the objects are left alone on a conveyor and no means has been shown to remove the object without endangering its shape.
  • the object is conveyed by the guide belts when it is supported by the removable portion of the support means.
  • Practice has shown, that it can easily be obtained that the object is taken along by the guide belts but immediately falls down when its support is removed.
  • This behaviour is rather common for food materials and probably for very many others too and possibly due to the following:
  • the object for instance a bag containing food material is compressed in the direction perpendicular to the direction of movement of the belts. During this compressing, but certainly after ending it, the resiliency of the filled bag is rather small and in practice enough to take it along, but certainly insufficient to clamp the bag between the belts, forming a bridge instead of falling down.
  • the removable portion of the support means consists of two opposing flaps pivotable about horizontal shafts from a first or supporting position in which the flaps are mainly horizontal to a second downwardly pending position.
  • US-A-4 026 421 shows a device for dispending objects by shifting them on opposing retractable flaps
  • US-A-2 510 343 shows a corresponding device in which the objects come from a conveyor and push each other onto pivotable flaps.
  • each of the guide belts engages at least three rollers which are adjustable in a direction transverse to the direction of movement of the guide belts.
  • This feature allows for adjustment of the width between the guide belts and adjustment of the location in the direction transverse to the direction of movement of the guide belt.
  • a further advantage of this elaboration of the invention is, that it is possible to have a fixed supply conveyor and an adjustable dropping location of the object with an apparatus which is very little more complicated than an apparatus without this feature.
  • NL-A-7100584 shows an apparatus for dropping objects at an adjusted location by laying them on a pair of pivotable flaps and moving these flaps to the desired dropping location.
  • This known apparatus is provided with a secondary driving system to displace the flaps in a transverse direction, which is far more complicated.
  • Figure 1 shows schematically a side view of an apparatus according to the invention
  • Figure 2 shows schematically a plan view of the apparatus of fig. 1.
  • FIG. 1 indicates a horizontal cylinder over which a conveyor belt 2 runs.
  • This belt returns via a reverse cylinder 3 towards the cylinder 1 and moves with its upper web in the direction of arrow 4 (vide fig. 2).
  • a vertical guide belt 8 runs over three rollers 5,6 and 7.
  • a corresponding guide belt 9 has been mounted which runs over rollers 10, 11 and 12.
  • rollers 7,12 and 6,11 can be shifted transversely to the direction indicated with the arrow 4. Such a displaced position has been indicated with the same references, but provided with an accent, wherewith the belt portions between rollers 6′,7′ and 11′,12′ respectively are parallel to the direction of the movement of the conveyor belt 2.
  • a bag 17 on belt 2 is shaped between the guide belts 8 and 9 to a predetermined width, which is reduced to the distance between the rollers 6 and 11 after adjustment of these rollers for handling the concerned bag.
  • the guide belts 8 and 9 take over the transport of the bag, which at the end of belts 8 and 9 is more or less pinched between these belts.
  • the bag is moved further on the plates 13 and 14 until the desired position is attained, which possibly may be determined by a stop member (not shown), the flaps 13 and 14 respectively pivot downwardly about the horizontal shafts 15 and 16 respectively and the bag falls perpendicular down.
  • the bags come with the correct orientation and in the correct position in boxes, one of which has schematically been indicated with 18.
  • the guide belts 8 and 9 may slacken or tighten too strongly which can be countered with tensioning devices known per se.
  • the shown embodiment has the advantage, that it is not necessary to place the bags accurately centered on the conveyor belt 2 and that they are always taken along by the conveyor belt and shaped by the guide belts 8 and 9, without any transfer, which could give rise to failures.
  • the bags are sufficiently gripped by the belts 8 and 9 to be taken along with them.
  • practice has shown, that the bags straight-forwardly fall down and are not retained by the forces exerted by the belts 8 and 9 on the bags.
  • the location of the rollers 6,11 and 7,12 not only determines the mutual distance between the belts, but also the location in transverse direction where the bags are discharged. It is, however, also possible to let the box 18 move towards the position necessary to receive the next bag. It is also possible to displace the shafts 15 and 16 in the transverse direction in order to locate the slit formed between the flaps 13 and 14 in the centerline of the shaped bags.
