Definitions

• the present invention relates to a procedure for packaging articles.
• Articles packed in boxes are usually more protected than articles packed in bags.
• the bags in fact, usually consist of a flexible packaging sheet which, folded on itself, covers the articles.
• the bag can be crushed and hit in such a way that even small strokes can jeopardize the integrity of the articles inside it.
• the article contained in the bag consists of a so-called “surprise product”, that is, an object that is distributed on the market so as not to be immediately recognizable from its packaging and that is discovered only after purchasing once the bag has been removed.
• the flexibility of the packaging sheet allows any purchaser to crush the bag without breaking it, folding it with the fingers for the purpose of touching the article inside.
• the main aim of the present invention is to provide a procedure for packaging articles that allows to pack articles so that they can be transported and distributed under greater safety conditions for their integrity and, in the case of "surprise products", so as to avoid that potential buyers can recognize the article without removing the package.
• Another object of the present invention is to provide a procedure for packaging articles which can overcome the above mentioned drawbacks of the prior art in the ambit of a simple, rational, eas and effective to use as well as low cost solution.
• Figure 1 is a schematic and partial axonometric view of the machine that realizes the procedure according to the invention
• Figure 2 is a longitudinal sectional view, on enlarged scale, of a detail of the machine of Figure 1 ;
• Figure 3 is a cross sectional view along the track plane III - III of Figure 1 ;
• Figure 4 is a cross sectional view along the track plane IV - TV of Figure 1 ;
• Figure 5 is a cross sectional view along the track plane V - V of Figure I ;
• Figure 6 is a side view, on enlarged scale, of a detail of the machine of Figure 1.
• reference numeral 1 globally indicated by reference numeral 1 is a machine that implements the procedure according to the invention.
• the machine 1 has a base frame, not shown in detail in the figures, carrying a packaging sheet 2 intended for the packaging of a series of articles 3.
• the packaging sheet 2 has a longitudinal extension and two longitudinal edges 4; in practice, the packaging sheet 2 has a length considerably greater than its width, and this allows to define the longitudinal direction of the packaging sheet 2 along which extend the aforesaid longitudinal edges 4.
• the packaging sheet 2 is initially wound in a reel 5 from which it is unrolled, carried on a worktop 6 and made to move along a direction of forward movement A substantially parallel to its longitudinal extension.
• the direction of forward movement A is substantially horizontal.
• the worktop 6 has side boards 7 which allow to fold the packaging sheet 2 so that the longitudinal edges 4 are slightly raised with respect to the central part of the sheet itself, causing it to take on a shape which, in cross section, is in the form of a U.
• the machine 1 can have an automatic dispenser that releases the articles 3, but alternatively it is not ruled out that this operation can be carried out manually.
• a first component of the machine 1 when it is stated that a first component of the machine 1 is arranged upstream of a second component, it means that the packaging sheet 2, which moves forward along the direction of forward movement A, first intercepts the first component and then the second one;
• a first portion of the packaging sheet 2 when it is stated that a first portion of the packaging sheet 2 is arranged upstream of a second portion of the packaging sheet 2, it means that the first portion is substantially closer to the reel 5 than the second one.
• the stretching apart bodies 8 are arranged at the longitudinal edges 4, on their inner side.
• two moving close bodies 9 Downstream of the stretching apart bodies 8 are provided two moving close bodies 9 that are arranged at the longitudinal edges 4, on their outer side.
• the stretching apart bodies 8 and the moving close bodies 9 mutually cooperate to approach a longitudinal edge 4 to another.
• the moving close bodies 9, are very close to one another and provide that, once the stretching apart bodies 8 are surpassed, the longitudinal edges 4 approach to one another, leaving the central part of the packaging sheet 2 under them.
• the reciprocal approach of the longitudinal edges 4, in practice, leads to the formation of a substantially tubular section 10 of the packaging sheet 2 having an open extremity 1 1, defined in the proximity of the moving close bodies 9, and the articles 3 inside.
• a compressed air duct 12 that blows air through the open extremity 1 1 of the substantially tubular section 10.
• the machine 1 Downstream of the moving close bodies 9, the machine 1 has a forward moving unit 13, 14, 15 that drives the packaging sheet 2 along the direction of forward movement A.
• the forward moving unit 13, 14, 15 comprises a first conveyor belt 13 on which rests the central part of the packaging sheet 2.
• the forward moving unit 13, 14, 15 also comprises at least a pair of driving rollers 14, 15, which are motorized and arranged on opposite sides of the juxtaposed longitudinal edges 4.
• the driving rollers 14, 15 press on the longitudinal edges 4, by gripping on them and driving them forward along the direction of forward movement A.
• the forwai'd moving unit 13, 14, 15 comprises two pans of driving rollers 14, 15, of which a first pair 14 and a second pair 15, arranged in succession above the first conveyor belt 13.
• a sealing unit 16 which seals the longitudinal edges 4 between them forming a sealed longitudinal edge 17.
• the machine 1 Downstream of the forward moving unit 13, 14, 15, the machine 1 is equipped with two opposite rotating members 18, which rotate around rotation axes R parallel to one another and transversal to the direction of forward movement A.
• the rotation axes R are arranged substantially horizontal, but alternative embodiments cannot be ruled out wherein the rotation axes R are vertical or oblique.
• the opposite rotating members 18 have at least a sealing surface 19, 20 and at least a cutting profile 21 able to come into contact with the substantially tubular section 10 on opposite sides of the same to seal it transversally upstream and downstream of each article 3 to form a plurality of closed packages 22 containing the articles 3 and have a first transversal sealing line 23 and a second transversal sealing line 24.
• each opposite rotating member 18 comprises two hammers 26 arranged at 180° with respect to the relative rotation axis R.
• Each hammer 26 has a first sealing surface 19 and a second sealing surface 20, between which is arranged a cutting profile 21.
• the hammers 26 are in contact with the substantially tubular section 10 first of all at the first sealing surfaces 19, that seal transversally the first transversal sealing line 23 of the closed package 22 arranged immediately downstream of the opposite rotating members 18.
• the subsequent rotation of the opposite rotating members 18 carries the second sealing surfaces 20 on the packaging sheet 2, by sealing it transversally at the second transversal sealing line 24 of the packaging sheet 2.
• the machine 1 Downstream of the opposite rotating members 18 the machine 1 has a moving away unit 28 that collects the closed packages 22 and moves them away; the moving away unit 28, e.g., consists of a second conveyor belt.
• the packaging procedure which can be realized by means of the machine 1 comprises the steps of: providing the packaging sheet 2 which, as already mentioned, has a longitudinal extension and two longitudinal edges 4. This step of the procedure consists in unrolling the packaging sheet 2 from the reel 5;
• the articles 3 are placed on the packaging sheet 2 at substantially regular intervals.
• the reciprocal distance D of the articles 3 on the packaging sheet 2 substantially con-esponds to the dimensions of the closed packages 22 in the direction corresponding to the direction of forward movement A;
• This step is performed by the machine 1 by means of the sealing unit 16;
• the air introduced into the substantially tubular section 10 through the open extremity 1 1 inflates the section itself and keeps it inflated even during the transversal sealing.
• the closed packages 22 obtained at the end of the procedure therefore, have two transversal sealing lines 23, 24 and are substantially swollen.
• Such closed packages 22 allow to package the articles 3 within an air cushion which ensures storage and transport under conditions of great safety for their integrity and which, in the case of "surprise products", prevents the packaging sheet 2 from being crushed so as to touch and recognize the articles 3 without removing the closed packages 22.
• the packaging sheet 2 is made of a heat-sealable material and the steps of sealing longitudinally and sealing transversally occur hot;
• this cutting step occurs at the same time as the sealing transversally.
• the sealing transversally and the cutting consist in making the substantially tubular section 10 pass between the two opposite rotating members 18, which rotate around the rotation axes R and which have the sealing surfaces 19, 20 and the cutting profiles 21 able to come into contact with the substantially tubular section 10 on opposite sides of same.
