Definitions

  • the present invention relates to a conveyor-wrapper unit for an automatic packaging machine of the so-called "sleeve" type.
  • the present invention comes within the specific context of automatic machines which are designed to package objects such as boxes or batches of products (for example casks, cans, bottles etc.), by means of pieces or sheets of packaging material, such as sheets of heat-shrink material, in which the said pieces are wrapped individually in the form of a "sleeve" around the objects, which are translated with continuous motion along a packaging path, in order then to pass the individual object/piece assemblies obtained into a heat-shrink oven, in order to heat to a specific temperature the pieces wrapped, which, when they cool, are heat-shrunk onto to the objects, and thus consolidate the packaging.
  • packaging material such as sheets of heat-shrink material
  • the segmented line for translation of objects comprises a series of mechanical units, and more particularly a conveyor belt, which is surmounted by longitudinal guides which form longitudinal ducts for the products, and is designed to supply the said products in longitudinal rows, in which the transverse ends of the said conveyor are secured to, and supported by, the said walls; a multiple-belt conveyor, along which the batches are formed, the transverse ends of which are secured to, and supported by the said walls; a batch former, disposed beneath the said multiple-belt conveyor, which is designed to form and supply in the downstream direction the batches of products, in which the said former has its transverse ends secured to, and supported by, the said walls; a first conveyor for supply of objects, which is oriented longitudinally, and is designed to supply the batches longitudinally along a first section of the packaging path, in which the said first conveyor has its transverse ends secured to, and supported by, the said walls; a second wrapping conveyor, which is oriented longitudinally, disposed downstream, and is slightly spaced relative to the said first
  • the unit wrapper substantially consists of two frames, which extend longitudinally and vertically, and are disposed respectively on both sides of the said second conveyor, with their respective lower ends resting on, and supported by, the said two lateral walls of the machine.
  • the said two frames additionally, each have respective guides for chains, in which the latter are wound in a closed path in two separate vertical-longitudinal planes, disposed on two opposite longitudinal sides of the second conveyor, and in which the said chains are designed to support the opposite ends of one or more wrapping bars, oriented transversely, which move through the said first and the said second aperture, along a closed orbital path which circumscribes the said second conveyor, such as to transport and wrap the pieces of packaging material around the objects.
  • the unit supplier is substantially disposed beneath the line for translation of the objects, and in the vicinity of the said first aperture, and supplies pieces of packaging material from the base upwards, via the said first aperture, and onto the initial portion of the said second conveyor.
  • the said machines are preferably assembled on the site of their future use, such that initially the base with the lateral walls is formed and/or positioned, and the operations of preparation-completion of the walls are then carried out (for example attachment of supports), and then the above-described mechanical units of the packaging machine are assembled on the said completed walls.
  • the said machines have different configurations, i.e. different completion of the walls in order to support different mechanical units, in which, for example, according to a first operative configuration, the first conveyor can consist of an inert sliding plate, on which there are translated batches of bottles thrust by suspended bars, and, according to a second configuration, the above-described first conveyor can consist of a belt conveyor which is wound around a closed path.
  • the object of the present invention is to eliminate the above-described disadvantages.
  • the object of the present invention is a conveyor-wrapper unit for a packaging machine of the "sleeve" type, which extends longitudinally, and is provided with a base comprising a first, longitudinal lateral upright and a second, longitudinal lateral upright, which are spaced transversely, between which there are disposed various conveyors, which are designed to translate from upstream in the downstream direction the objects to be packaged, along a segmented straight packaging path, in which there are provided wrapping means, which are designed to wrap around the objects pieces of packaging material, whilst the said objects are being translated from upstream in the downstream direction along the said segmented straight translation path, in which the said conveyor-wrapper unit is characterised in that it comprises two suspended plates which extend longitudinally and vertically; in that the said two suspended plates are supported respectively in a detachable manner, one from the said first upright and the other from the said second upright, by means of securing/release means; in that the said suspended plates support two or more conveyor means, which are oriented longitudinally,
  • first advantage of the present invention consists in the fact that the completion and assembly of some mechanical units of the machine is quick and easy, and does not require execution of difficult operations between the walls of the machine, with a consequent reduction in the execution times, and thus a corresponding reduction of the final production cost of the machine.
  • the packaging machine consists of a frame formed from longitudinal members and cross members which substantially form two lateral frame-uprights indicated as 1a and 1b.
  • each of the said securing clamps 77a, 4a, 5b, 4b, 5b consists of a square jaw 9, which is perforated in the vicinity of the four vertices, and is disposed against the outer side of the longitudinal member 3b, in which the said holes support in a through manner four screws 10, 11, 12 and 13, which are oriented transversely, disposed two above, and two below, the said longitudinal member 3b, the shanks of which extend transversely, and pass through holes provided in the suspended plate 6b, which is disposed against the inner side of the longitudinal member 3b itself, in which the said screws 10, 11, 12 and 13 support at their inner end four clamping nuts, of which only two, 11d and 10d can be seen in figure 4b, in order to form a parallel clamp, which clasps the said longitudinal member 3b.
