Definitions

  • the present invention relates to improvements to machines or devices for the ordered arrangement of products destined for packaging. More in particular, the present invention relates to a device for the formation of mutually superposed layers of products to be packaged, such as rolls of toilet paper, packs of napkins or the like.
  • a device for the formation of mutually superposed layers of products to be packaged such as rolls of toilet paper, packs of napkins or the like.
  • State of the art In the tissue paper converting industry, to produce for example toilet paper, kitchen towels, paper napkins and handkerchiefs or the like, there is frequently the need to produce packages of several products arranged according to superposed layers. A plurality of superposed layers of rolls, packs of napkins or the like are packaged with heat-sealable plastic films, to form packages destined for sale.
  • WO-A-2006/134622 discloses devices and methods for the production of groups of three layers of superposed products for packaging. In these devices alignment and compacting of the products formed in single layers is critical, as incorrect alignment of the products causes defects during subsequent packaging or even jamming of the packaging lines downstream of the layering device. Objects and summary of the invention
  • the invention provides measures to solve or alleviate the aforesaid problems.
  • the invention provides a device for the formation of mutually superposed layers of products to be packaged, comprising:
  • a compacting wall positioned approximately orthogonal to the direction of feed of the conveyors and thereunder, in a position such that the lowering movement of the moving surface carries the layer or layers deposited thereon approximately to the height of the compacting wall, so that the products interacting with the compacting wall are correctly ordered or compacted.
  • the compacting wall is provided with a movement towards and away from the moving surface, to facilitate lowering of the moving surface with the layers of products deposited thereon and subsequent compacting of said layers.
  • Figures 1 to 3 show an operating sequence in a simplified schematic representation of the device according to the invention in side view
  • Figure 4 shows a schematic front view according to IV-IV of Figure 3. Detailed description of embodiments of the invention
  • the present invention can be incorporated in a device designed and controlled as described in WO-A-2006/134622, which should be referred to for greater details, for the part not described in the present specification, which is limited to the innovative and characterizing aspects of the present invention.
  • the device indicated as a whole with 1 , includes a stacking surface 3 movable vertically according to the arrow f3 (Fig. 2).
  • a fixed stop wall 5 is associated with the stacking surface to define the position of complete insertion of layers S of products P, in the example illustrated formed by way of example of rolls of toilet paper or the like.
  • the device To stack the layers S1, S2, S3 on the vertically movable stacking surface 3 the device includes a pair of substantially superposed conveyors: a first lower conveyor 7 and a second upper conveyor 9.
  • a sliding surface 7A is associated with the lower. conveyor 7, along which the layers S of products P are pushed by means of the conveyor 7.
  • the conveyor 7 has transverse push bars 7B, 7C.
  • the conveyor 7 is formed by two endless flexible members substantially parallel and distanced by a degree sufficient to contain therebetween the layers to be stacked and which support the transverse push bars 7B, 7C.
  • the upper conveyor 9 has a similar structure, with a sliding surface 9A and with a single push bar 9B carried by two endless flexible members (for example a belt or a chain) which form the conveyor 9.
  • a compacting wall 11 extending substantially vertically, is arranged under the sliding surface 7A of the lower conveyor 7.
  • the compacting wall 11 is provided with a movement according to the arrow f11 ( Figure 2).
  • the device 1 comprises (see Figure 4) a separator element that serves to temporarily separate superposed layers of products P during the stacking process.
  • the separator element comprises two surfaces 13A, 13B carried by slides 15A, 15B movable according to the double arrows f15A and f15B along guides 17A and 17B.
  • the movements of the stacking surface 3, of the compacting wall 11 , of the conveyors 7, 9 and of the surfaces 13A, 13B are obtained with actuators of conventional type, not shown.
  • the operating cycle of the device described above is clearly understood by examining the sequences of Figures 1 to 3.
  • a first step the lower conveyor 7 pushes, by means of the pusher or push bar 7B, a first layer of products P onto the surface 3.
  • This surface is located at a height approximately corresponding to the height of the front edge of the sliding surface 7A.
  • the layer S1 has been placed on the stacking surface 3 the latter is lowered (arrow f3) to take the position in Figure 2.
  • Lowering of the stacking surface 3 preferably takes place with the compacting wall 11 in the position of Figure 1 , i.e. distanced from the volume inside which the stacking surface 3 moves.
  • the compacting wall 11 is not movable and is located in the position of Figure 2.
  • the two conveyors 7 and 9 Before, during or after lowering of the stacking surface 3 from the position of Figure 1 to the position of Figure 2, the two conveyors 7 and 9 have pushed a second layer S2 and a third layer S3 of products P into an intermediate position along the sliding surfaces 7A, 9A, by means of the transverse bar 7C of the conveyor 7 and the transverse bar 9B of the conveyor 9 respectively.
  • the layers of products are fed to the conveyors 7, 9 in a known manner by means of an oscillating conveyor belt or other suitable device, not shown.
  • the movement of the conveyors 7, 9 pushes the layers S2, S3 towards the stacking surface 3, obtaining superposing of the three layers S1 , S2, S3 on this surface.
  • the position of maximum feed of each of the three layers is defined by the wall 5.
  • the separator surfaces 13A, 13B are moved from an idle position (indicated with a dashed line in Figure 4) to an operating position, shown with a solid line in Figure 4.
  • the layer S2 is pushed by the bar 7C by means of the conveyor 7 onto the separator surface formed by the surfaces 13A, 13B moved towards each other, thereby preventing direct sliding of the layer S2 on the layer S1 below.
  • the two conveyors 7, 9 move in synchronism, no sliding occurs between the two layers S2 and S3, and therefore no separator surface is required therebetween.
  • the arrangement described above achieves the advantage of compacting the products P of the lower layer S1 and maintaining them in the ordered arrangement due to the fact that they are contained between the wall 5 and the compacting wall 11.
  • the products P of the layer S1 are held by lateral walls 19A, 19B ( Figure 4).
  • the products P of the layers S2, S3 above are retained laterally by containing walls 21 A, 21 B forming the continuation of the walls 19A, 19B.
  • the walls 19A, 21 A and 19B, 21 B respectively can be mutually integral, i.e. formed only by two opposite walls, each suitably interrupted or slotted to allow passage of the separator elements or surfaces 13A, 13B.
  • the separator elements or surfaces can have a comb structure to . penetrate through the lateral walls, which can therefore have a structural continuity between lower portion 19A, 19B and upper portion 21 A, 21 B.
  • the conveyors 7, 9 can be controlled with an alternating movement so that the push bars 7C, 9B oscillate around the end position shown in Figure 3.
  • these push bars 7C, 9B form a compacting element of the products P of the layers S1 , S2, S3 preventing the risk of accidental movement of the products P during the lifting steps towards the packaging position above.
  • the push bar 7B acts as compacting element at the moment (shown in Figure 1) in which the layer S1 is lowered to the lower level ( Figure 2) in contact with the compacting wall 11.
