Definitions

  • the present invention relates to machines designed to produce packs of rolls of products, for example, packs of rolls of toilet paper, consisting of at least two layers of products.
  • Such machines have a line which feeds the products on various parallel rows, a station in which layers of the products are prepared, consisting of rows of products positioned side by side, a station in which at least two of the layers are stacked one on top of the other to form a pack, and a station in which the packs prepared in this way are wrapped in a sheet of synthetic material.
  • the machine must preferably also be able to produce a pack consisting of a single layer.
  • the wrapping station comprises an elevator plate designed to receive at least one layer forming the pack, and preferably at least two layers already positioned one on top of the other, and to place said pack on the worktable of the unit designed to wrap the sheet around it.
  • Each layer consists of at least two products which normally have an almost cylindrical shape and which must be on top of two identical products with the axis horizontal. Therefore, the two layers, placed one on top of another, are characterised by a very unstable equilibrium basically because the individual products are of a soft consistency and so are deformed and slightly flattened at their contact surface.
  • the layers move forwards on said surfaces, pushed by pushers which keep them precisely one on top of the other, and are unloaded onto the elevator, forming the desired multi-layer pack of products on the elevator.
  • the aim of the present invention is to overcome the above-mentioned disadvantages by providing a simple, reliable and economical solution which does not include an oscillating surface.
  • the machine disclosed comprises, in the direction of product feed, a first fixed horizontal surface, a second fixed horizontal surface coplanar with the first and set at a distance from the first which will be defined below, a third fixed horizontal surface below the second fixed horizontal surface and set at a distance from it equal to at least the maximum thickness of the layer of products, and a fourth fixed angled surface which connects the first fixed surface to the third fixed surface.
  • the distance which separates the first and second fixed surfaces must be sufficient to allow each layer to slide from the first to the fourth fixed surfaces without interfering with the second.
  • the above-mentioned surfaces although defined as fixed surfaces, and remaining fixed once correctly positioned, may preferably be adjustable to adjust their distance to the thickness of the layers to be stacked.
  • the present invention also comprises first thrust means which act upon the layers supported by the first and second surfaces, second thrust means which act upon the layers supported by the third surface, and third thrust means which act upon the layers supported by the angled or fourth surface.
  • the first, second and third thrust means consist of pairs of chains bearing horizontal cross-members at right angles to the chains.
  • the step between the cross-members of the first thrust means is half the step between the cross-members of the second and third thrust means.
  • the cross-members of the first and third thrust means are perfectly synchronised, whilst the cross-members of the second thrust means are out of phase by half a step relative to the cross-members of the second thrust means.
  • first and second fixed surfaces there are two more side chains which between them support a slat conveyor with at least one slat section and at least one empty section whose size is at least equal to the maximum size of the layers in the direction of feed.
  • the slat conveyor will preferably have two equal slat sections, separated by empty spaces of the same size.
  • Movement of the slat conveyor is synchronised with the thrust means, the rear edge of the slat section synchronised with the cross-members of the thrust means in the direction of feed.
  • a mobile surface driven into position as a continuation of the first fixed surface, its size, in the direction of feed, being at least equal to the distance between the first and the second surfaces minus the size of the slat section in the direction of feed.
  • the first layer intended to form the pack is fed forwards on the first fixed surface, reaches the empty area of the slat conveyor and slides onto the fourth angled surface and then onto the third fixed surface.
  • the next layer intended to form the pack reaches the edge of the first fixed surface together with a slat section, goes onto the latter and is accompanied as far as the second fixed surface.
  • the layers positioned on the second and third fixed surfaces are then simultaneously pushed onto the elevator device downstream.
  • the figures illustrate the surface 1 on which the single layers 2 arrive, each layer consisting of six rolls 21.
  • first thrust means 6 consisting of a pair of chains 61 stretched between pulleys from 63 to 68, and having equidistant horizontal cross-members 62.
  • Second thrust means 9 similar to the means 6 and comprising chains 91 and cross-members 92 are attached to the surface 8 and third thrust means 10, similar to the previous ones and comprising chains 101 and cross-members 102 are attached to the surface 7.
  • the step of the cross-members 92 and 102 of the thrust means 9 and 10 is double the step of the cross-members 62 of the thrust means 6.
  • cross-members of the thrust means 6 and 9 are perfectly synchronised with one another, in the sense that the cross-members of the means 9 are positioned at every other cross-member of the means 6, whilst the cross-members of the means 10 are out of phase by half a step relative to the cross-members of the means 9.
  • Two identical slat sections 104 and 103 are supported between the chains 11. Said sections are preferably separated from one another by a distance equal to the distance separating the surfaces 4 and 5, having a size in the direction of layer feed at least equal to the size of the layers.
  • the chains 111 are driven at the same speed, and are perfectly synchronised with the thrust means 6, 9 and 10.
  • a mobile surface 400 driven by a piston cylinder unit 401 into position as a continuation of the first fixed surface 4, having a size, in the direction of feed, at least equal to the distance between the first 4 and the second 5 fixed surfaces minus the size of the slat section 103/104 in the direction of feed.
  • the invention operates as follows.
  • the surface 400 is moved forwards to guarantee the continuity of the supporting and sliding surface for the layer 2 from the surface 4 to the surface 5, from which the layer is thrust onto the elevator plate, not illustrated, by the cross-member 62.
  • a first layer 2 arrives at the end of the surface 4 with the slat section 104 positioned as illustrated in Figure 2, and continues moving onto the angled surface 8 as far as the surface 7, accompanied by the second thrust means 9 which receive it on the surface 8 and push it forwards to the surface 7.
  • the next, second layer intended to form the pack reaches the edge of the surface 4 together with the slat section 104, is received by the latter and accompanied to the surface 5.
  • the first thrust means When the second layer is on the surface 5, the first thrust means continue pushing it until it is on the elevator device located downstream.
  • the first layer lying on the surface 7 below is collected by the third thrust means 10 and pushed onto the elevator, on which it is positioned precisely below the second layer.
  • the step between the cross-members 102 of the thrust means 10 is double the step between the cross-members 62 of the first thrust means, allowing the first layer to remain stationary on the surface 7 until the second layer arrives.
  • each slat section 103/104 in the direction of feed, is synchronised with one out of every two cross-members 62.
  • the cycle is repeated in an identical manner.
  • the first, second and third pusher means, the slat conveyor 11, and the piston cylinder unit 401 are controlled in a synchronised fashion by a single programmable processor.
  • elevator means such as a plate which moves vertically, onto which the two layers on the surface 5 and 7 drop without sliding one on top of the other.
  • all of the thrust means and the slat conveyor may be driven, in such a way that they are synchronised with one another, by a single motor.
