Description

  • The present invention relates to a method of packaging a product, in particular a food product, such as for example a chocolate bar of substantially rectangular shape, in a sealed package, in which the product is brought continuously on a linear conveyor , we position a sheet of rectangular heat-sealable packaging material on the path of this product, we simultaneously drive the product and the paper on the linear conveyor by folding the sheet around the product so as to form two flaps of unequal lengths respectively adjacent to the large faces of the product, this coated product is then introduced into a housing of a rotary turning device which advances intermittently, the flaps are sealed one on the other along a longitudinal edge of said product, which has the effect of forming a flap disposed substantially in the extension of the large underside of the product.
  • It also relates to a device for packaging a product, in particular a food product, such as for example a chocolate bar of substantially rectangular shape, in a sealed package, for the implementation of the above method, this device comprising a linear conveyor for bringing the products to be continuously packaged and a device for positioning a sheet of substantially rectangular heat-sealable packaging material on the path of this product, means for simultaneously driving the product and the paper on the linear conveyor by folding the sheet around the product so as to form two flaps of unequal length respectively adjacent to the large faces of this product, a rotary turning device which advances intermittently comprising at least one housing for receiving a product thus coated, means for sealing the flaps one on the other along a longitudinal edge of said pro duit, which has for effect of forming a flap disposed substantially in the extension of the large underside of this product.
  • To meet health and safety standards in the presentation of food products such as for example chocolate bars, there is an increasing tendency to use leaktight packaging produced using heat-sealable packaging material. . In the automatic packaging lines, the product is brought by a linear conveyor and drives the packaging material placed on its path. After sealing the flaps of packaging material which are formed when the sheet is folded around the product, a flap of packaging material is obtained which must then be folded over the underside of the product after forming and folding down. side folds. However, this operation requires a reversal of the product, which generally results in difficult handling due to the existence of this flap which can prove to be troublesome.
  • A machine of this type is described in US Pat. No. 4,648,236 and comprises a turning device comprising members for taking up rectangular flat products with wrapping paper folded around two sides of these products and for turning them over. 180 ° and to seal the packaging during the inversion. This machine is not suitable for packaging chocolate bars because of the requirements which are specific to these products.
  • The present invention proposes to overcome this drawback by providing a succession of manipulations for which the existence of this flap does not constitute discomfort.
  • For this purpose, the method according to the invention is characterized in that the lateral folds and said flap are formed by means of a traditional folding box which is one of the fixed stations of the rotary turning device, in that that the partially wrapped product is extracted after it has been turned over, the turning device having rotated 180 °, in that the lateral folds are sealed in a position substantially perpendicular to the large faces of the product by a pressing element and an element support, in that the said flap is folded and the lateral folds on the underside of the product which moves continuously at the outlet of the turning device, this face being disposed above the product as a result of said turning, and in that this flap is sealed against said face lower.
  • According to a first embodiment, the side folds are first folded, then said flap over the side folds.
  • According to a second embodiment, the flap is first folded, then said lateral folds over said flap and a banner printed around the product is placed, this banner consisting of a rectangular sheet wrapped around the product, so as to form a sleeve open at its ends and so as to superimpose two edges of this sheet.
  • According to a particularly advantageous embodiment, the lateral folds are sealed by preheating the heat-sealable packaging material by means of two heating tapes arranged to advance parallel to the product placed on the linear conveyor, then by exerting pressure on the folds lateral heat-sealable material preheated by means of cooled pressing members, said plies being maintained in a position substantially perpendicular to the large faces of the product by at least one support and guiding element.
  • To seal the side folds, they are held by means of said support and guide element by moving this element parallel and at the same speed as the product, this element being positioned between the two folds and above the large upper face. of the product.
  • The packaging device according to the invention is characterized in that it comprises a traditional folding box for forming the lateral folds and said flap, this box being one of the fixed stations of the turning device, means for extracting the product partially wrapped, after being turned over, means for sealing the lateral folds in a position substantially perpendicular to the large faces of the product by a pressing element and a support element, means for bringing the product into abutment in at least one station arranged to fold said flap and the side folds on the underside of the product, and to glue this flap on the underside of the product, this face being disposed above the product as a result of said inversion.
  • According to a preferred embodiment, said means for sealing the lateral folds comprise two heating tapes arranged on either side of the product, means for advancing these tapes parallel to the products arranged on the linear conveyor, and at least two pressing members cooled to exert pressure on the side plies of preheated heat-sealable packaging material, said side plies being held in a position substantially perpendicular to the large faces of the product by at least one support and guide element.
  • This support and guide element for the side folds is preferably constituted by a pallet mounted on a transport chain arranged to move this pallet parallel to the product and at the same speed, this pallet having dimensions and a shape such that it can engage between the side folds arranged substantially vertically and provide support for said side folds, when subjected to the pressure of the pressing members.
  • The station arranged for folding up said flap preferably comprises a lifting device for lifting the product, lateral folders for folding down said lateral folds and movable folding stops for folding up said flap.
  • The present invention will be better understood with reference to the description of an exemplary embodiment and the appended drawing in which:
    • Fig. 1 represents a schematic view of the packaging device according to the invention,
    • fig. 2 represents a detailed view of the rotary turning device,
    • fig. 3 represents a schematic view of the station for folding the side folds and the flap,
    • fig. 4 represents a first form of folding of the packaging material on the product,
    • fig. 5 represents a second form of folding of the material on the product with the addition of a banner, and
    • fig. 6A and 6B respectively represent two perspective views illustrating the embodiment of the packaging of FIG. 4 and the embodiment of FIG. 5.
  • With reference to the figures, the device according to the invention comprises a linear conveyor 10 constituted by a conveyor belt, a chain or any other means known per se for bringing products 11 which are, in the example shown, chocolate bars. It should be noted that the chocolate bars are relatively delicate products which have a non-negligible thickness, and edges which are generally inclined because the product is molded and must be able to be extracted from the mold. The packaging material must be folded and sealed around the product and, due to the thickness of the product, the folds must be formed precisely using folding members. A device 12 makes it possible to distribute sheets 13 of substantially rectangular shape of a heat-sealable packaging material. These sheets are entrained by the product during its movement in the direction of arrow A and are folded around the front face of this product so as to form two flaps 14 and 15 of unequal lengths. This is how the product, partially packaged in the sheet of heat-sealable packaging material 13, is conveyed to a rotary turning device 16 comprising receiving cells 17 intended to receive the products and to rotate them 180 ° in the direction of arrow B, so as to turn them over. During this movement, the flap 15 is sealed against the flap 14 by means of a first clamp 18 intended to preheat the heat-sealable material and by means of a second clamp 19 arranged downstream of the clamp 18, and arranged to exert pressure on both flaps and to cool the heat sealable material previously heated.
  • The clamps 18, 19, which are of identical construction but one of which 18 includes heating members (not shown), and the other of which 19 includes cooling members (not shown), have two jaws 60 and 61 respectively integral with two levers 62 and 63 articulated relative to each other at 64.
  • Mechanical, pneumatic or hydraulic control members make it possible to open the two jaws 60 and 61 as shown more particularly in FIG. 2, to bring them into positions 60 ′ and 61 ′ illustrated in broken lines.
  • A folding box 20 mounted on a support 20 ′ forms the flap 21 in fact constituted by the part of the flap 15 beyond the flap 14 after the sealing of said flaps, at the same time as the lateral folds 9 adjacent to the short lateral sides of the product. The folding box, which is known per se and exists on all traditional machines for packaging chocolate bars, consists of two central reel 20a and two pairs of lateral folding ramps 20b which respectively have the function of initiating and then forming the side folds 9. The partially wrapped product is then extracted from the rotary inversion device. The product is now placed on its upper face, called a "mirror" in the case of a chocolate bar, which will allow the folds to be folded over and the flap 21 on its underside which is kept arranged above the product more during the turning maneuver. Before this last operation, the product passes through a device for sealing the lateral folds which is composed on the one hand of two lateral heating bands 22 driven in parallel and possibly at the same speed as the product placed on a linear conveyor. These two heating strips have the function of preheating the heat-sealable packaging material at the side pleats. This sealing device also consists of two pressing members 23, for example rollers designed both to exert lateral pressure on the side plies and to cool the preheated heat-sealable packaging material. It further comprises supporting and guiding elements for the lateral folds constituted by pallets 24 mounted on a chain 25 arranged to drive the pallets parallel and at the same speed as the product. These pallets have a shape and dimensions such that they can be positioned above the large upper face of the shelves, between the lateral folds held vertically, and serve as a support to oppose the pressure of the pressure rollers 23. It will be noted that the lateral folds are necessarily held vertically during this sealing operation since the two superimposed sheets which form each of the two folds move relative to each other when they are brought from the horizontal position into the vertical position. To avoid creases and wrinkling of the packaging material when the side pleats are folded against the underside of the product, these folds must be sealed in an upright position and therefore require an internal support resistant to the pressure exerted by the pressure rollers. This procedure guarantees regular preheating and correct and reliable sealing.
  • At the exit of this treatment station, the product is entrained towards a station, illustrated in more detail in FIG. 3, which allows both the side folds to be folded down and the flap 21 to be folded over the large face of the chocolate bar. This flap is preferably glued with a line of glue or dots of glue, and / or by sealing against the external surface of the packaging material already covering the underside of the product in a suitable station equipped with a gluing device and / or sealing 50.
  • This station 50 comprises a fixed support 51 and an arm 52 articulated on this support and preferably carrying several sealing heads 53 which can be heated to an adequate temperature to ensure spot sealing of the packaging material. The arm 52 can pivot in the two opposite directions illustrated by the double arrow C. This device ensures the sealing of the flap on the underside of the product 11.
  • It will be noted that the products are fed continuously to the rotary turning device 16. This device advances intermittently and brings the products successively opposite the clamps 18 and 19, and into the folding box 20. At the outlet of the rotary turning 16, the products are again taken up continuously and brought to the station for folding down the side folds 9 and the flap 21, then to the station for sealing this flap. Products advance intermittently in these two stations.
  • This continuous-intermittent path is due to the fact that certain stations (clamps 18, 19, folding 20, folding down the flap 21 and the side folds 9, sealing) are fixed, and the products must remain there for a predetermined period of time.
  • Referring to Figure 2, the rotary turning device 18 consists of a wheel at the periphery of which is formed a series of cells 17 oriented radially. Products 11 are pushed to the interior of a cell brought in front of the linear conveyor by means of a pusher 30 fixed to the end of an arm 31 associated with a drive mechanism (not shown) which has the function of moving this pusher according to a path 32 shown in broken lines. The products partially packaged in the sheet of heat-sealable packaging material are rotated to the station comprising the clamp 18 corresponding to the first preheating phase 19, the role of which has been defined above. They are then brought to the station comprising the clamp 19 corresponding to the second cooling phase which makes it possible to seal the two flaps 14 and 15. The folding box 20 is arranged to shape the side folds 9, which has the effect of raising the flap 21 which therefore consists of a central part and two raised ends forming lateral wings 33 formed on either side of the central part.
  • When the product has made a 180 ° rotation, it is supported by a finger 34 which pushes it out of the housing and drives it along a guide 35 to the last station described with reference to FIG. 3. The finger 34 is integral with a drive chain 36 and constitutes with the guide 35 a linear conveyor arranged to bring the product to the last processing station.
  • Figure 3 illustrates the station designed to fold the side folds and the flap 21. For this purpose, the finger 34 pushes the product in abutment against a stop 37 disposed at the end of a lifting device 38 arranged to lift the product. A stop 39 is fixed on a pivoting support 40 to stop the flap 21 and the lateral wings 33 arranged on either side of the flat part of this flap in a predetermined position. The support 40 also comprises two folding templates 41 arranged to form the folds at a perfectly determined location when a movable folding member 42 folds the flap 21 by moving from its position 42 shown in solid lines in its position 42 ′ shown in broken lines, while the lifting member 38 rises while carrying the product, and while movable lateral folders 44 advance to fold down the lateral folds 9. The flap 21 then forms an acute angle with the shelf and is folded over it by the fixed edge of the movable member 42 while the tablet is moved by the finger 34.
  • Depending on the presentation of the finished product that we want to obtain, we can proceed to fold the packaging material on the product in two different ways.
  • With reference to fig. 4, in a first folding phase, the lateral folds 9 of packaging material are folded over the underside 43 of the product 11, and in a second phase, the flap 21 is folded and fixed on the folded side pleats. This form of folding means that the side folds and the flap must be large enough for the packaged product to look like a finished product. Consequently, this operating mode results in a fairly large consumption of packaging material.
  • In the second folding method illustrated in fig. 5, in the first folding phase, the flap 21 of packaging material is folded and fixed on the underside 43 of the product 11. In the second phase, the side folds are folded and fixed 9 on the folded flap and, the product packaged by this method does not have an appearance of a finished product because the side folds remain visible, in a third phase we surround this packaged product with a banner 45 of paper printed. This form of folding allows a flap of dimensions smaller than those necessary in the other case and results in a saving of packaging material.
  • The flap is fixed in a manner known per se by means of one or more lines or dots of adhesive deposited on one of the two surfaces of the packaging material in contact with one another on the face lower 43 of the product, or by sealing, by means of the device of the station 50 described above.
  • Fig. 6A illustrates the packaging process corresponding to the packaging of FIG. 4. The products 11, which are chocolate bars, are brought in the direction of arrow A. The sheets 13 of packaging material coming from a supply device 70 with two rollers 71 and 72 are brought to the trajectory of the tablets, then arranged around these tablets.
  • These tablets are then introduced into the rotary turning device 16 which rotates intermittently in the direction of the arrow B. The clamps 18 and 19 (not shown in this figure) seal the two surfaces of packaging material to form a tubular packaging 73 around the shelf.
  • The folding box 20 (not shown) forms the side folds 9 and the flap 21.
  • The side heating strips 22 heat the heat-sealable material in the area of the side folds and the pressure rollers 23 seal these side folds.
  • Lateral folders 14, movable in the direction of the double arrows E, ensure the placement of these folds and a device (see fig. 3) folds the flap 21. This flap is then sealed by the device 50 (see fig. 1 ).
  • Turning members, known per se and not shown, turn the shelves 11 over before removing them.
  • Fig. 6B repeats the elements of FIG. 6A from the rotary turning device 16. The packaging is carried out as above until the lateral folds 9 are put in place and that of the flap 21.
  • These tablets are also intended to receive a banner 45. For this purpose, the packaging line comprises a supply station 80 with two rollers 81 and 82 of packaging material. It is usually a sheet of printed paper. This sheet 83, previously cut, is interposed on the path of the shelves, then is folded in a known manner to form a sheath around this product. The two longitudinal edges are superimposed and then glued to each other.
  • These various operations made it possible first of all to carry out a longitudinal sealing along one of the longitudinal edges of the product then to carry out a lateral sealing at the level of the lateral folds. In As a result, the product is tightly packed and meets current safety and hygiene requirements. It is understood that certain functions could be fulfilled by means somewhat different from those which have been used in the embodiment illustrated by the figures. Thus the turning device followed by a linear conveyor could be replaced by a larger turning device or by several devices of this type arranged one after the other and providing at their periphery a set of stations making it possible to perform all required operations.
