Definitions

  • the present invention generally relates to vacuum skin packaging of products.
  • the present invention relates to a machine and a method for vacuum skin packaging of a product arranged on a support.
  • Vacuum packaging is a well known process for packaging a wide variety of products, in particular food products.
  • vacuum skin packaging is commonly employed for packaging food products such as fresh and frozen meat and fish, cheese, processed meat, ready meals and the like.
  • Vacuum skin packaging is described for instance in FR 1 258 357, FR 1 286 018, AU 3 491 504, US RE 30 009, U.S. Pat. No. 3,574,642, U.S. Pat. No. 3,681,092, U.S. Pat. No. 3,713,849, U.S. Pat. No. 4,055,672, and U.S. Pat. No. 5,346,735.
  • Vacuum skin packaging is basically a thermoforming process.
  • the product is typically placed on a rigid or semi-rigid support (such as a tray, a bowl or a cup).
  • the support with the product placed thereon is put in a vacuum chamber, where a film of thermoplastic material, held by vacuum in a position above the product placed on the support, is heated to soften it.
  • the space between the support and the film is then evacuated and finally vacuum above the film is released to cause the film to drape down all around the product and seal to the surface of the support not covered by the product, thus forming a tight skin around the product and on the support.
  • US 2007/0022717 discloses a machine for gastight packaging an object using a film material.
  • the machine has a lower tool for supporting two trays and an upper tool having cutting devices and facing the lower tool.
  • a film is interposed between the upper tool and the lower tool.
  • the film is firstly cut to the size of the peripheral rims of the trays, and is applied subsequently and/or simultaneously to the peripheral rim in a gastight manner.
  • a vacuum is situated in the surrounding region of the tray to cause deep-drawing of the film in response to the formation of a pressure drop.
  • US 2005/0257501 discloses a machine for packaging a product arranged in a tray.
  • the machine has a lower tool for supporting the tray and an upper tool with a cutting device.
  • the film is clamped along an edge surrounding the tray and is deformed by the upper tool in a direction extending away the product.
  • the space surrounding the product is then evacuated, the film and the edge of the tray are sealed and the film is then cut by the cutting device.
  • U.S. Pat. No. 3,481,101 discloses a method for making skin packages using a support provided with a plurality of apertures in a lip thereof. According to this method, after the tray is filled, a heated cover film is draped upon the tray and vacuum is applied so that the air within the package is drawn from the package and the film is drawn into heat sealing condition with the tray to form a hermetic seal of the cover to the tray lip. Additional apertures may be provided in the upper sidewalls of the tray whereupon the heated film is not only drawn into sealing contact with the lip of the tray, but also is drawn down partially into the cavity.
  • EP 320294 discloses a skin packaging method wherein a product loaded tray provided with a vent in its sidewall is placed on a vacuum platen, an excess of the thermoplastic film is held over the tray by a frame and heated until it starts to sag over the product, then vacuum is applied from below the tray to pull the film to conform to the surface of the product and over and around the rim of the tray in a thermally set crimp seal. The excess film is then trimmed.
  • the film is cut to the size of the support within the chamber formed by the upper tool and the lower tool, by means of the cutting devices provided on the upper tool.
  • the Applicant has faced the problem of providing a machine for vacuum skin packaging of a product arranged on a support that (similarly to the skin packaging methods of U.S. Pat. No. 3,481,101 and EP 0320294) reduces the risk of leaving air pockets in the package and that at the same time overcomes at least one of the aforesaid drawbacks of the machines of US 2007/0022717 and US 2005/0257501, i.e.: it is simpler and more compact than these machines and minimizes excess film that is cut from the package and scrapped during or at the end of the packaging process.

  • Vacuum is released from below the support 7 and then the fourth piston 54 preferably pushes the inner slidable element 531 of the base unit 53 in the vertical direction indicated by the arrow A 7 of FIG. 3 , until the inner slidable element 531 is again substantially aligned with the sliding plane 20 (see FIG. 5 h ).
  • the support 7 may continue sliding step-by-step along the sliding plane 20 in the horizontal direction indicated by the arrow A 1 under effect of the conveyor belt 21 .
  • the film cutting assembly 4 cuts a further film sheet as described above (the backing block 42 is pushed upwardly until the backing element 422 faces the cutting device 40 , the cutting device 40 is horizontally pushed against the backing element 422 thus cutting the further film sheet, the cutting device 40 is moved away from the backing element 422 and the backing block 42 is pulled downwardly until the backing plate 421 faces the film transfer plate 51 a ), the film transfer plate 51 a is pushed against the backing plate 421 with the further film sheet arranged between them, vacuum is applied between the heatable surface of the film transfer plate 51 a and the further film sheet so that the film transfer plate 51 a holds the further film sheet, and the film transfer plate 51 a holding the further film sheet is moved away from the backing plate 421 .
  • the film transfer plate 51 b is preferably moved away from the base unit 53 ( FIG. 5 g ) and the support 7 is raised at the level of the sliding plane 20 ( FIG. 5 h ). Then, with a single step of the stepping motor unit 22 , the conveyor belt 21 removes the support 7 from the base unit 53 and brings a further support with a further product on the inner slidable element 531 of the base unit 53 . The further support is brought on the inner slidable element 531 and said element 531 is lowered, while the rotating cylinder 50 preferably rotates by an angle of about 180° about its axis X, thereby exchanging the positions of the film transfer plates 51 a , 51 b .
  • the heating surface 510 is then lowered to engage the rim of the support 7 carried by the outer fixed element 530 of the base unit 53 . Consequently, the film transfer plate 51 a holding the further film sheet is now above the further support.
  • the operations shown in FIGS. 5 d to 5 h are then repeated to provide for a further product packaged according to the vacuum skin package technique.
  • the operation of the machine 1 cyclically repeats according to the above synchronism, thereby implementing vacuum skin packaging on a number of supports 7 with respective products 8 loaded thereon that are sequentially provided onto the sliding plane 20 .
  • providing the holes 70 in the support 7 advantageously allows removing air from within the support 7 underneath the film sheet 61 even after the paper film 61 is brought into airtight contact with the rims of the support 7 .
  • This advantageously allows removing more air from within the support 7 , thereby minimizing the amount of residual air left in the support 7 at the end of the vacuum skin packaging process, and accordingly minimizing the risk of forming air pockets.
  • this allows continuing removing air from the support 7 even after the film sheet 61 is released from the heatable surface 510 of the film transfer plate 51 b .
  • This advantageously allows reducing the residual amount of air inside the package at the end of the vacuum skin packaging process.
  • the film sheet 61 may be air tightly fixed to the rims of the support 7 before starting extracting air from within the support 7 .
  • the film transfer plate 51 and the outer fixed element 530 form a “vacuum chamber”.
  • the film transfer plates 51 a , 51 b advantageously allows firstly cutting the film sheet 61 and subsequently transferring the film sheet 61 into the position above the product 8 and the support 7 . In this way, no excess film is required to allow the film to be pulled from the film roll 6 and to be held in place above the product 8 . Further, this advantageously allows providing a film cutting assembly 4 separated from the packaging assembly 5 .
  • the film cutting assembly 4 is advantageously very simple, since it performs the cuts at environment temperature and pressure. No complicated solutions are required for performing the cuts in extreme conditions such as very high temperatures or very low pressures.
  • the packaging assembly 5 is advantageously very simple and compact, since it does not have to integrate any cutting device. The resulting machine 1 is therefore simpler and more compact then the known machines.
  • the presence of two alternating film transfer plates 51 increases the heating time of the film sheet 61 (i.e. the time during which the film sheet 61 is in contact with the heatable plate of a film transfer plate 51 a , 51 b ).
  • heating of the film sheet 61 starts when a film transfer plate (e.g. 51 b ) holds the film sheet 61 by adhesion, it continues while the film transfer plate 51 b is moved away from the backing plate 421 , while the rotating cylinder 50 rotates thus exchanging position of the film transfer plates 51 a , 51 b , while the film transfer plate 51 b is pushed into contact with the base unit 53 and while air is extracted from within the support 7 .
  • This time is much longer than the heating time allowed by the known machines. Therefore, advantageously, the predefined temperature at which the heatable surfaces 510 of the film transfer plates 51 a , 51 b are heated may be lower than in prior art machines.
  • the base unit 53 ′ preferably comprises an outer element 530 ′, a fixed baseplate 531 ′ and an adapter 532 ′ with four levelling feet 533 ′.
  • the fixed baseplate 531 ′ is connected to a fixed stem 540 of the third piston 54 and has four passing holes (not visible in the drawings).
  • the adapter 532 ′ leans on the fixed baseplate 531 ′ with the four levelling feet 533 ′ engaging the passing holes and projecting on the lower side of the fixed baseplate 531 ′.
  • the adapter 532 ′ may be configured so that, when it leans on the fixed baseplate 531 ′, the four levelling feet 533 ′ are external to the fixed baseplate 531 ′ and they project on the lower side of the fixed baseplate 531 ′.
  • the fixed baseplate 531 ′ and the adapter 532 ′ engage the aperture 20 a of the sliding plane 20 so that upper surface of the adapter 532 ′ is aligned with the sliding plane 20 .
  • the outer element 530 ′ has a base and a sidewall defining a central cavity.
  • the base has one or more vacuum holes (not shown in the drawings) suitable for connecting the central cavity with the vacuum pump.
  • the central cavity of the outer element 530 ′ is preferably dimensioned to allow the fixed baseplate 531 ′ and the adapter 532 ′ to slide in the central cavity.
  • the base of the outer element 530 ′ is preferably connected to a movable cylinder 541 of the third piston 54 .
  • the heatable surface 510 of the film transfer plates 51 a , 51 b is heated to a predefined temperature.
  • the film cutting assembly 4 preferably starts cutting film sheets 61 from the unrolled portion of film 60 as described above (before each cut, the backing block 42 is pushed upwardly until the backing element 422 faces the cutting device 40 , the cutting device 40 is horizontally pushed against the backing element 422 thus cutting a film sheet 61 , the cutting device 40 is moved away from the backing element 422 and the backing block 42 is pulled downwardly until the backing plate 421 faces the film transfer plate 51 b ).
  • the film transfer plate 51 b is pushed against the backing plate 421 with the film sheet 61 arranged between them, vacuum is applied between the heatable surface of the film transfer plate 51 b and the film sheet 61 so that the film transfer plate 51 b holds the film sheet 61 , and the film transfer plate 51 a holding the film sheet 61 is moved away from the backing plate 421 .
  • one of the supports 7 with a product arranged thereon (not visible in FIG. 6 a ) is sliding along the sliding plane 20 under effect of the conveyor belt 21 (not shown in FIG. 6 a ), until it reaches the aperture 20 a engaged by the base unit 53 ′ and is accordingly arranged on the adapter 532 ′.
  • the rotating cylinder 50 preferably rotates by 180° about is axis X, so that the positions of the film transfer plates 51 a , 51 b are exchanged. Accordingly, the third piston 52 b has now its axis vertically oriented and the film transfer plate 51 b holding the film sheet 61 is now above the support 7 and the product 8 (see FIG. 6 b ).
  • the outer element 530 ′ is then moved upwardly in the vertical direction indicated by the arrow A 7 of FIG. 3 by the moving cylinder 541 of the fourth piston 54 , until the outer element 530 ′ touches the rim of the support 7 and the levelling feet 533 ′ of the adapter 532 ′ rests on the base of the outer element 530 ′ (see FIG. 6 c ).
  • the outer element 530 ′ is further moved upwardly in the vertical direction indicated by the arrow A 7 of FIG. 3 by the moving cylinder 541 of the fourth piston 54 , thus raising the adapter 532 ′ (and the support 7 resting on it) and detaching it from the fixed baseplate 531 ′.
  • the stroke of the outer element 530 ′ ends when the fixed baseplate 531 ′ leans against the base of the outer element 530 ′ (see FIG. 6 d ).
  • the film transfer plate 51 b holding the film sheet 61 is pushed downwardly until the film sheet 61 covers the aperture of the support 7 (as shown in FIG. 6 e ), the edges of the film sheet 61 being fixed to the rim of the support 7 in a airtight manner.
  • the film transfer plate 51 b is pulled in the vertical direction indicated by the arrow A 5 of FIG. 3 by the third piston 52 b , thereby moving it away from the base unit 53 (see FIG. 6 f ), and vacuum in the outer element 530 ′ is released.
  • the outer element 530 ′ is moved downwardly in the vertical direction indicated by the arrow A 7 of FIG. 3 by the moving cylinder 541 of the fourth piston 54 , thus lowering the adapter 532 ′ (and the support 7 resting on it) and bringing it again into contact with the fixed baseplate 531 ′ (see FIG. 6 g ).
  • the outer element 530 ′ is then further moved downwardly in the vertical direction indicated by the arrow A 7 of FIG. 3 by the moving cylinder 541 of the fourth piston 54 , until the outer element 530 ′ disengages the aperture 20 a of the sliding plane 20 and the support 7 (see FIG. 6 h ). In this way, the support 7 may continue sliding along the sliding plane 20 in the horizontal direction indicated by the arrow A 1 under effect of the conveyor belt 21 .
  • the two film transfer plates 51 a , 51 b . may be operated according to the synchronism described above.
  • the machine 1 incorporating the base unit 53 ′ according to the second variant has the same advantages as the machine 1 incorporating the base unit 53 ′ according to the first variant, i.e.: minimization of the risk of forming air pockets, minor amount of residual air inside the pack at the end of the vacuum skin packaging process, the use of a simpler vacuum chamber, no excess film required to allow the film to be pulled from the film roll 6 and to be held in place above the product 8 , simplicity of the film cutting assembly 4 and of the packaging assembly 5 , increased productivity, and increased heating time of the film sheet 61 .
  • the base unit 53 ′ according to the second variant advantageously allows adapting the machine 1 to the use with a variety of supports of different types in a very simple way.
  • the packaging assembly 5 incorporating the base unit 53 ′ properly operates if the overall height of the adapter 532 ′ with the levelling feet 533 ′ and the support 7 equals the height of the central cavity of the outer element 530 ′. Therefore, in case the machine is firstly used for packaging first products on a first type of supports having a first height, and successively the machine should be used for packaging second products on a second type of supports having a second height, the machine 1 can be adapted to the use with the supports of the second type by simply changing the adapter 532 ′ with a new adapter having levelling feet with the suitable height.
  • the levelling feet 533 ′ of the adapter 532 ′ are adjustable, adaptation is performed by simply adjusting the levelling feet 533 ′. Both operations (changing the adapter or adjusting the levelling feet thereof) are advantageously very simple, since the adapter is merely resting on the fixed baseplate 531 ′, and accordingly may be removed from the base unit 53 ′ and mounted in the base unit 53 ′ in a very easy way.
  • pre-cut film sheets of the suitable dimensions may be stacked and taken up, one at a time, by the film transfer plates 51 a and 51 b and used in the packaging process described above.
  • a suitable configuration of the packaging assembly 5 may foresee that the film transfer plates 51 a , 51 b are arranged parallel to the base unit 53 and they are moved vertically by relative pistons that allow said film transfer plates 51 a , 51 b to be raised and lowered as needed.
  • the pistons may be connected to a cylinder rotating about a vertical axis, so as to horizontally displace the pistons with the film transfer plates 51 a , 51 b .
  • This alternative packaging assembly may run the following steps: lowering a first film transfer plate (designed as 51 a above) over the stack of pre-cut film sheets, applying vacuum through the first film transfer plate 51 a to take up the top film sheet of the stack, raising the first film transfer plate 51 a with the pre-cut film sheet adhered thereto, rotating the cylinder by a suitable angle to bring said first film transfer plate 51 a over a base unit 53 and at the same time a second film transfer plate 51 b above the stack of pre-cut film sheets, and lowering the first film transfer plate 51 a to carry out a vacuum skin packaging process as described above.
