Definitions

  • the invention relates to an article wrapping machine with extensible film, the obvious purpose of which is to wrap an article by means of a portion of film that is finally sealed in closure, and which has means for supplying film from a reel towards the article to be wrapped, with means that make the correct positioning between the article and the film to be wrapped, as well as the folding and final sealing of the film once the article is wrapped.
  • the machine is of the type in which the entry and exit of the items to be wrapped is carried out on the same front, in order to be able to integrate in said wrapping machine, if necessary, weighing and labeling equipment.
  • Some types of wrapping machines of articles or products with extensible film are known, being able to cite among them the one described in the patent US 4501106, intended to wrap trays containing certain products, so that in said machine the tray to be wrapped accesses through a feeding car that has it in a fixed position on an elevator, regardless of the size of the tray and the dimensions of the product contained in it.
  • This elevator then moves vertically upwards with the tray, until reaching the film sheet destined to wrap said tray, sheet that is supplied from a coil and pulled, for delivery, by means of an extraction clamp, said machine having Folders of the film to wrap the tray laterally and inferiorly and then move on to a band where the final closure takes place by hot sealing, preferably.
  • the portion of film that is extracted by the extraction clamp is always the same, regardless of the size of the tray and the height reached by the product contained in it. This causes that, when packing trays that present a lot of height on the opposite side of the feed reel, as the amount of film available on that side is fixed, the film must be stretched so that a very elastic and high micron film must be used to prevent it from being possible to break.
  • the folder removes the long part of the film, that is, the one that will cover the base of the article, stealing directly from the reel but, while the folder pushes the stolen film under the tray, at the same time it pushes said tray against the stop thereby increasing the pressure of the film against the tray and against the articles contained therein, in such a way that it can sometimes cause damage to the tray itself and even in the articles without being sufficiently delicate.
  • this overpressure of the film forces the use of films with an oversized weight.
  • the film cutting blade acts at a fixed point in the machine cycle, regardless of the size of the article, since the movement of said blade comes from the general camshaft of the machine, so that whatever means of folding provided in this machine always steal an amount of film from the coil, this sometimes represents an unnecessary waste of film.
  • the recommended machine has been designed to solve all this problem to full satisfaction, based on the fact that the different movements and operational phases of it are programmed, depending always of the dimensions of the article, controlling both the placement of said article to be wrapped, as well as the size of the portion of film to be used, as well as the movements of the extraction clamp, of the folding elements and of the blade itself. cut, so that all this will be based on the dimensions of the article and the film used.
  • one of the characteristics of the invention is that the article will be arranged on the corresponding elevator in a position determined by the microprocessor, depending on the dimensions thereof, so that the distribution of the film in the envelope will achieve closure by superposition on its lower base.

  • the bolus body is expected to It is made of flexible plastic material and that it is opportunely coupled to a head, also made of plastic, through a neck designed to produce the precise folding and recovery movements for the normal operation of the folding blades.
  • the film extraction clamp is provided with a variable longitudinal movement to extract a portion of film proportional to the transverse perimeter of the article to be wrapped, the necessary amount of film being extracted in each case to perform optimally, with the precise amount of film, the last folding or subsequent folding.
  • the extraction clamp has a variable movement in the direction of the product exit, moving below the sealing strip. This movement is very important because thanks to it it is possible to control the stretching of the film in the final folding.
  • the extraction clamp will make a stretch of the film that will be proportional to the degree of flexibility of the film and the necessary cutting tension.
  • Another novel feature of the wrapping machine of the invention is that it includes lateral clamps that hold the film when it is fully extended and tensioned in the longitudinal direction, these clamps being laterally movable to make a stretch of the film in a transverse direction, which It will be programmable to the width of the film used and the length of the article to be wrapped.
  • These lateral clamps have a movement of approach to the variable film, in order to be able to hold the film by its external edges, whatever the width of the film feeding reel.
  • the displacement of the lateral clamps is fixed, in order to always achieve the same degree of stretching, independent of the width of the film.
  • the corresponding film feeding reels have a brake whose activation and deactivation occurs in a programmed way depending on the item to be wrapped. This brake remains activated until the lifting of the article causes contact with the film, at which time the brake is deactivated and the article continues its ascent by stealing an additional amount of film from the reel, the brake being connected again before the elevator race is completed, to obtain the tension in the film necessary to facilitate its subsequent cutting.
  • the exact moment of braking is determined by the programmer, depending on the product to be wrapped and, therefore, the specific film needs, managing to optimize the use of the least amount of film possible in each wrap, also avoiding breakage of the film by exceeding the elastic limit of the film, making the wrap with an optimal tension for the best presentation of the wrapped item.
  • the wrapping process begins with the introduction of side folding blades and a rear folding blade, so that to make the lateral folds the tension of the film will be maintained and the machine control will order the deactivation of the film clamping system at the exact moment when the side presser presses the film and starts folding.
