Definitions

  • the present invention relates to a device intended for wrapping fruit, having as one of its essential characteristics a double head, which makes it possible to achieve much greater utilization of the operating time of the wrapping machine.
  • the machines of known type have different systems for feeding the tubular mesh element to the bag closure region, which is customarily constituted in the lower part of a metal tube on which is inserted the tubular mesh element mentioned above.
  • the feed assemblies have rollers which make contact on the tubular mesh element situated on the cylindrical body, causing it to advance by the amount required to produce the different bags in succession.
  • GB 2087338 discloses an apparatus intended for packing sausages or cheese.
  • This apparatus is a double-headed wrapping device comprising a carrier disc as a common support for two parallel hollow mandrels. These mandrels are used for feeding tubular film onto the article to be wrapped. In one preparatory position, one mandrel may be stocked with a new film, whereas in the second position the mandrel serves for filling the tubular film with products.
  • the axis of rotation of the common support for the mandrels is preferably horizontal.
  • the apparatus of GB 2087338 is disadvantageous, in particular with respect to the operating time during the wrapping process.
  • the present invention provides a double-headed device as described in claim 1, so that each of the said heads or units has a tubular body intended to occupy two positions in succession, one of which is a working position in which it will receive on the outside the tubular mesh element which will be withdrawn successively by the rollers for the filling and separation of the individual bags, and the other a position in which the said tubular element is separated towards the outside of the machine, allowing the placing in position of a new tubular mesh element which will be used at the appropriate moment when the one which is being used has run out. All that is required for the said change is the rotation, through a predetermined angle, of a frame assembly for supporting both tubular elements, so that the loss of useful working time on the machine is insignificant.
  • the device which is the subject of the present invention has a single plate or frame which carries the two tubular bodies for guiding the tubular mesh element, including an independent motor unit intended to effect the rotation of the carrier plate through a predetermined angle, which may be 180°, in order to permit the change.
  • Each of the cylindrical elements for supporting and guiding the tubular mesh element has an assembly of drive rollers located on the upper or lower part of the cylinder, including the corresponding gear trains for driving from a main motor, and the said rollers being mounted on rocker arms or linear systems actuated by cylinder and piston assemblies of the hydraulic or pneumatic type, which are independent of one another, in order to allow the said rollers to tilt or move linearly between an operating position, in contact against the mesh element arranged on the cylindrical guide element, and an open position, directed towards the outside, in which the said rollers cease to make contact with the mesh element so that the latter can be introduced, corresponding to the position for the exchange of the said tubular mesh element.
  • the said rollers may also be separated for other operational purposes.
  • the device has a single filling station integrated with the corresponding entry hopper for the pieces of fruit and also the corresponding closure and transverse cutting mechanisms.
  • FIGS 1 to 7 represent various diagrammatic views of arrangements of feed rollers of the type known at present.
  • Figure 8 is a diagrammatic plan viewof the carrier plate for the two stations or heads of the device.
  • Figure 9 is a diagrammatic view in which can be seen the relative position of the tubular element and the rollers for withdrawal of the latter.
  • FIGS 10 and 11 are simplified views which show different operating positions of the apparatus.
  • Figure 12 is a diagrammatic view of a variant with the rollers located in the lower part.
  • Figure 13 is a view in side elevation of one of the units of the device, a detail thereof being shown in Figure 14.
  • Figure 15 is a plan view of the device, in which the arrangement of the two heads is shown diagrammatically.
  • Figure 16 is a view in elevation corresponding to Figure 15.
  • Figures 17 and 18 are respectively views in side and front elevation of the device in the variant of application of the rollers in the lower part.
  • rollers 17 and 18 act on a covering 19 of the tubular element, which causes marked concave regions of pinching of the tubular mesh element.
  • Figure 6 which corresponds to a plan view of Figure 5, there can be observed the arrangement of the rollers with respect to the covering of the tubular element.
  • the variant in Figure 7 shows two rollers 22 and 23 of a resilient material which, by means of a pressure P, forms a concave profile, which rollers adapt to the periphery of the cylindrical body 24 in order to effect the withdrawal of the tubular mesh element.
  • the device which is the subject of the present invention has two units 25 and 26, each of which carries a tubular body to receive a fragment or section of the mesh element, and the respective drive rollers, the two units being incorporated in the same rotary frame or plate 27 driven, in a form which is not shown in detail, by a motor 28.
  • each of the cylindrical elements will receive on the outside the tubular mesh element 29, Figure 9, which will be fed in an upward direction by means of the rollers 30 and 31 which will occupy the active position shown in the said Figure 9 in which they are at a tangent to the tubular mesh element 29 in order to feed it to the upper part of the rigid tubular guide body, and another position shown by means of the numbers 30' and 31', in which the said rollers are separated from the working position, allowing the placing in position of a new mesh element or permitting any other manipulation to be carried out.
  • Figure 10 can be observed the arrangement of the two tubular bodies 32 and 33, one of which is shown in a working position in which the upper rollers 34 feed the mesh to the upper part of the tube 32, in order to receive the pieces of fruit from the single hopper 35, while the other position shows the arrangement of the outer tubular mesh element 36 prepared for subsequent use.
  • the bags are subject to closure at both ends 37 and 38, each closure being complemented by a conventional cutting operation.
  • FIG. 12 a variant is shown in which the plate 39 which carries the two units of the machine is arranged in the upper part with the tubular bodies arranged towards the bottom and the feed rollers 40 and 41 likewise arranged in the lower part.
  • Figure 11 shows the two corresponding tubular bodies 42 and 43, as well as the single upper hopper 44.
  • the plate or frame which carries the two heads is driven by means of a motor 45 with a transmission, not shown in detail, for driving the plate through a predetermined angle, usually 180°, necessary for the changing of the working unit.
  • the upper rollers are driven by means of a motor 46 which, by means of a gear-wheel 47, transmits its drive to the intermediate gears 48 and 49 corresponding respectively to one or other of the two units of the double machine which in turn transmit their rotation by means of the gearwheels 50 and 51 and the corresponding belts or chains 52 and 53 to the upper rollers 54 and 55 intended to feed the tubular mesh element to the upper mouth of the rigid tubular body 56.
  • rollers 54 and 55 are mounted on individual rocker arms, not shown in detail, in order to allow them to assume the positions shown previously in Figure 9, for which purpose cylinder and piston devices 57 and 58 are provided, preferably hydraulic, which make it possible to tilt the said rollers from the working positions to the positions intended for filling and other manipulations.
  • Another, upper, cylinder and piston assembly 59 makes it possible to tilt the plate 60 which carries the transmission elements associated with the main motor.
  • Figures 17 and 18 show a version in which the single motor 61, by means of the wheel 62, drives the gears 63 and 64 which transmit their motion to the rollers 65 and 66, arranged on the lower part of the rigid cylindrical body 67.
  • the cylinder and piston elements equivalent to those described previously are shown by the numbers 68, 69 and 70.
