Definitions

  • the present invention relates to a method and a device for wrapping products.
  • the invention finds application to advantage in the continuous packaging of edible products such as chocolates, sweets and the like, to which reference is made explicitly in the following specification albeit with no limitation in general scope implied.
  • Conventional devices generally comprise a wrapping drum with peripheral carrier units such as grippers or pockets by which the products, partly enveloped in respective leaves of wrapping material bent to a "U" profile around each one, are caused to advance along a set path and through dedicated folding stations.
  • peripheral carrier units such as grippers or pockets by which the products, partly enveloped in respective leaves of wrapping material bent to a "U" profile around each one, are caused to advance along a set path and through dedicated folding stations.
  • Each leaf bent thus to a "U" profile must undergo further folding steps in order to produce a closed wrapper, including a first step whereby the two parts of the leaf projecting from the side corner edges of the relative product are bent inward to form a semifinished tubular wrapper about the product. The open ends of the tubular wrapper are then secured, for example by fashioning twist closures.
  • EP 0816229 which relates to a device for packaging small objects in respective wrappers with gathered ends.
  • the preamble of claim 1 is based on this prior art.
  • the patent device is designed to envelop a product partially in a leaf of wrapping material, forming an intermediate wrap folded about the product and presenting what is substantially a "U" profile.
  • the product thus appears with one edge of the leaf of wrapping material projecting from each of two opposite faces, extending parallel and beyond the dimensional outline of the part-enveloped product. Thereafter, one only of the two edges is bent and flattened against a sealing area of the other edge, to which it remains attached.
  • the folding method briefly outlined is somewhat complex, given that the two edges projecting from the product must be bent in opposite directions. This means that the device by which the folding steps are performed must necessarily be equipped with elements capable of alternating motion, operating in different directions and orientations, a factor that tends both to complicate the structure and to impact negatively on the cost of building and maintaining the device.
  • the object of the present invention is to provide a method and a device of the type in question, such as will be unaffected by the drawbacks described above.
  • a further object of the invention is to provide a device for wrapping products that can be rendered structurally simple, and therefore economic and efficient.
  • numeral 1 denotes a product wrappable by the method according to the present invention.
  • Such a product 1 might for instance be a chocolate, toffee or similar item of confectionery appearing parallelepiped in shape, albeit the shape in question is indicated by way of example and with no limitation implied.
  • the product 1 might also be a sweet or candy of spherical or oval shape.
  • the product 1 is first enveloped partially in a leaf 2 of wrapping material, in such a way as to form an intermediate wrap presenting a first flap 3 and a second flap 4 projecting from the product 1 on opposite sides of a free face 5 presented by the selfsame product 1.
  • the free face 5 is the one side face of the product 1 that will remain unassociated or at least not in direct contact with the leaf 2, when this first step of the method has been completed.
  • the leaf 2 assumes a configuration presenting a substantially U-shaped profile, partly enveloping the product 1, with the free face 5 and the two opposite end faces 6 of the product 1 left exposed, albeit one only of these same faces is visible in the drawings ( figures 1a and 2a ).
  • the leaf 2 is associated with three side faces of the product 1, leaving the fourth side face exposed.
  • the leaf appears, on completion of the partial enveloping step ( figure 1a ), with the first flap 3 and second flap 4 extending away from one another in opposite directions, departing from respective opposite corner edges of the product 1 and occupying substantially the same plane as that occupied by the free face 5 of the product 1.
  • the leaf appears, on completion of the partial enveloping step ( figure 2a ), with the first flap 3 and second flap 4 extending away parallel one to another and substantially perpendicular to the free face 5.
  • the first flap 3 only is bent in a predetermined direction F1 (rotated anticlockwise as seen in figures 1a-1c and 2a-2d ) toward the free face 5 of the product 1 and toward the second flap 4, and offered flush to the second flap 4, thereby establishing an area 7 of contact between the first and second flaps 3 and 4.
  • the area 7 of contact might be sealed with hot melt glue, or welded.
  • the first flap 3 is rotated approximately 180° about a line parallel and adjacent to one corner edge of the product 1, to the point of covering the free face 5 of the product and uniting with the second flap 4 ( figure 1b ).
  • a proximal portion of the first flap 3 is at first rotated through approximately 90° about the line parallel and adjacent to the corner edge, whilst a distal portion of this same flap 3 is united and thereupon rotated together with the second flap 4 into the same configuration as shown in figure 1b ( figure 2c ).
  • first flap 3 and the second flap 4 will preferably be pressed one against the other along the area 7 of contact to complete the longitudinal seal.
  • the pressing step is effected while the two flaps 3 and 4 lie in flush contact with one another and parallel to the free face 5 ( figure 1b ), or rather on completion of the step whereby the first flap 3 is folded against the second flap 4.
  • the pressing step can be effected when the first flap 3 enters into contact with the second flap 4 ( figure 2b ), or after the second flap 4 has been rotated finally into a position that produces the same configuration as in figure 1b ( figure 2c ) .
  • first flap 3 and second flap 4 are bent further in the predetermined direction F1 and flattened against the product 1, so as to form a tubular wrapper 8 ( figure 3a ).
  • first and second flaps 3 and 4 are bent together and flattened against a flank face 5a of the product 1 lying substantially perpendicular to the free face 5.
  • tubular wrapper 8 presents two ends 9 projecting longitudinally beyond the end faces of the product 1, which are pinched and sealed with cold glue or hot melt adhesive or by a welding operation, preferably with the formation of twist type closures 10 ( figure 3b ), employing a familiar procedure not described further.
  • the device 11 comprises a conveyor 12 presenting a plurality of slots 13 ordered in succession and caused to advance along a predetermined feed path 14 in a predetermined feed direction F2.
  • the conveyor 12 consists in a wrapping wheel carried by a bulkhead 15 of the packaging machine, set in rotation at a substantially constant angular velocity about a horizontal axis 16 normal to the bulkhead 15 and turning clockwise (as seen in the accompanying drawings) in the feed direction F2 aforementioned.
  • the predetermined feed path 14 describes an arc to a circle. In alternative embodiments of the device (not illustrated) the feed path 14 might describe a different trajectory, for example rectilinear.
  • Each slot 13 is designed to admit a product 1 partly enveloped in the leaf 2 of wrapping material, and with the first flap 3 and the second flap 4 projecting from the slot 13.
  • each of the single slots 13 is created between the pincer ends 17 of a respective main gripper 18.
  • the main grippers 18 are mounted in angularly equispaced positions around the wrapping wheel 12, radiating from the axis 16 of rotation.
  • the single slot 13 is afforded by a pocket 19 formed in the cylindrical surface of revolution presented by the wrapping wheel 12.
  • the pockets 19 are angularly equispaced.
  • the device 11 is equipped with a loading station 20 located on the predetermined feed path 14.
  • the loading station 20 comprises a push rod 21 set in motion transversely to the feed path 14 between a position distanced from the path 14 and a position close to the selfsame path 14, in such a way that each successive product 1 can be directed against a relative leaf 2 of wrapping material lying parallel to the feed path 14, occupying a position radially outside the compass of the slots 13 and facing one respective slot 13, then propelled into the slot 13.
  • the leaf 2 of wrapping material is driven forward and forced to wrap around three faces, remaining pinned between the product and the inside walls of the slot 13.
  • the flaps 3 and 4 projecting from the slot 13 remain parallel to the predetermined feed path 14 and lie at least in part against peripheral bearing faces 22 of the wheel 12 interposed between the slots 13 and substantially parallel likewise to the path 14 aforementioned.
  • This configuration of the "product 1 and leaf 2" assembly is as indicated in figure 1a .
  • the bearing faces 22 are afforded by terminal portions of the grippers 18, whilst in the alternative embodiment of figures 5a-5d , the bearing surfaces 22 consist in portions of the conveyor 12 proper, or rather of the cylindrical surface of revolution presented by the wrapping wheel 12, interposed between the pockets 19.
  • the device 11 also comprises a fixed restraint 23 positioned close to the predetermined feed path 14, such as will intercept the two flaps 3 and 4 of each leaf 2 in succession, bending the first flap 3 in a predetermined direction F1 opposite to the feed direction F2, toward the free face 5 of the product 1 and into contact with the second flap 4.
  • the restraint 23 is embodied as a plate presenting a curved surface 24 breasted closely with the bearing surfaces 22, and combining thus with these same surfaces 22 to delimit a passage 25 for the flaps 3 and 4.
  • the plate 23 also presents a locating edge 26 positioned close to the bearing surface 22 and directed toward the loading station 20. The distance between the edge 26 and the bearing surfaces 22 is such that the first flap 3 of the leaf will be intercepted by the selfsame edge 26, bent back and flattened against the product 1 and the second flap 4 ( figure 4c ).
  • This configuration of the "product 1 and leaf 2" assembly is as indicated in figures 1b and 2c .
  • the device 11 is equipped with retaining means 27 operating on the endmost edges of the leaf 2 before it is bent and folded.
  • the device 11 further comprises ducts 29 connected to a vacuum pump 29a (illustrated schematically) and opening onto a top surface 30 of the plate 23 adjacent to the locating edge 26.
  • the top surface 30 is substantially flat and disposed parallel to the predetermined feed path 14 followed by the products 1 taken up at the loading station 20.
  • the first flap 3 of the leaf 2 is held by the flat surface 30 before and during the insertion of the product 1 into the slot 13 together with the leaf 2.
  • the top surface 30 and the curved surface 24 of the plate 23 converge toward the locating edge 26.
  • a sealing station 31 located along the feed path 14, at a point beyond the fixed restraint 23.
  • the function of this station 31 is to secure the two flaps 3 and 4 one to another longitudinally, along the area 7 of mutual contact.
  • the flaps 3 and 4 are also pressed together at this same station 31.
  • the sealing station 31 comprises a pair of presser tools 32 and 33 capable of movement toward or away from one another in a direction transverse to the predetermined feed path 14 and engaging the two flaps on opposite sides of the area 7 of contact ( figure 4d ).
  • the presser tools 32 and 33 move in a radial direction, relative to the axis 16 of rotation of the wrapping wheel 12, and are positioned in such a way that the two united flaps 3 and 4 will pass between them.
  • the device 11 might be equipped, for example, with a plurality of inboard presser tools 32 mounted to the wrapping wheel 12, each alongside a respective gripper 18, and just one radially outboard presser tool 33 located at the sealing station 31.
  • the sealing station 31 incorporates a presser tool 34 associated with the bearing surfaces, such as will force the area 7 of mutual contact against one of the bearing surfaces 22, and the two flaps 3 and 4 one against the other.
  • the presser tool 34 comprises a roller 35 installed preferably within a housing 36 afforded by a portion 37 of the plate 23 at the end remote from the locating edge 26 ( figure 5c ).
  • the roller 35 is also anchored to the plate 23 through the agency of spring means 38, by which it is biased toward the bearing surface 22. Retained by one of the surfaces 22, the two flaps 3 and 4 are caused by the rotation of the wrapping wheel 12 to pass under the roller 35, which presses them one against the other.
  • a folding station 39 where the first flap 3 and the second flap 4 are bent together in the direction denoted F1, that is to say in the original folding direction of the first flap 3, and flattened against the product 1.
  • the folding station 39 is equipped with an auxiliary gripper 40 such as will retain the product 1 momentarily when released by the main gripper 18 during the folding step.
  • the auxiliary gripper 40 is disposed transversely to the main gripper 18 and presents two pincer ends 41, one only of which is illustrated in figure 4e , placed so as to engage the end faces 6 of the product 1.
  • the auxiliary gripper 40 is capable of movement between an operating position of close proximity to the main gripper 18, when the main gripper is in the folding station 39, and a non-operating position distanced from the wrapping wheel 12 so as not to interfere with the movement of the selfsame wheel.
  • the jaws 41a of the auxiliary gripper 40 straddle one pincer end 17 of the main gripper 18 with sufficient clearance to ensure there is no interference with this same end 17 when the pincer ends 41 close on the product 1.
  • Numeral 42 denotes a folder capable of movement in a radial direction, transversely to the feed path 14, and penetrating between the open pincer ends 17 of the main gripper 18, in such a way as to engage the area 7 of contact and flatten it against one flank face of the product 1.
  • the product is taken up by the auxiliary gripper 40 and released by the main gripper 18.
  • the folder 42 can then slip between the product 1 and the pincer end 17 of the main gripper 18 situated on the side remote from the auxiliary gripper 39, engaging the flaps 3 and 4 and skimming the flank face of the product 1, with the result that the flaps 3 and 4 are flattened against the selfsame flank face.
  • the product 1 is taken up again by the main gripper 18 and released by the auxiliary gripper 39 ( figure 4f ).
  • the product 1 is carried into a further station equipped with means of conventional type, not illustrated, by which the two ends 9 of the tubular wrapper 8 are secured.
  • Such means will be designed preferably to form the ends into twist closures 10.
  • the folding station 39 is equipped with a take-up gripper denoted 43, indicated in figure 5d , which operates in conjunction with an auxiliary push rod 44 housed slidably in the pocket 19.
  • the auxiliary push rod 44 is capable of movement between a retracted position, lying at the back of the pocket 19, and an extended position occupying the mouth of the pocket 19.
  • Each pocket 19 is equipped with a respective auxiliary push rod 44 which, when the pocket 19 draws into alignment with the loading station 20, moves from the extended position to the retracted position so as to accompany the movement of the product 1 into the pocket 19, and when the pocket 19 is aligned with the folding station 39, moves from the retracted position to the extended position so as to ease the product 1 out of the pocket 19 and between the jaws 45 of the take-up gripper 43.
  • one of the jaws 45 will operate as a folder, engaging the flaps 3 and 4 and flattening them against one flank face of the product 1.
  • the folding station 39 lies next to the sealing station 31, immediately beyond the end portion 37 of the plate 23.
  • This same end portion 37 presents a projection 46 extending radially away from the axis 16 of the wrapping wheel 12 and furnished with radial grooves 47 shaped to match corresponding members 48 presented by one jaw 45 of the take-up gripper 43 ( figure 6 ).
  • the take-up gripper 43 is capable of movement between a position distanced from the projection 46, and a position of engagement in which the members 48 are inserted in the grooves 47 to provide a uniform bearing surface for the product 1 wrapped partially in the leaf 2 of wrapping material.
  • the projection 46 also combines with the members 48 to bend and flatten the flaps 3 and 4 against the product 1.
  • the gripper will close firmly on the wrapper 8 and transfer the product 1 to a further station equipped with means designed to secure the two ends 9 of the tubular wrapper 8, for example by forming a twist closure 10 on each one.
  • the first and second flaps 3 and 4 are disposed mutually parallel and perpendicular to the free face 5 of the product.
  • the leaf 2 thus assumes a configuration substantially of "C" profile, leaving one face 5 of the product 1 exposed ( figure 7a ) as in the examples described previously.
  • the two flaps 3 and 4 are then folded one toward the other, by rotating the first flap 3 clockwise and the second flap 4 anticlockwise, as viewed in figure 7a , at least partially, to the point at which the flaps 3 and 4 can be united and secured one to another by a hot or cold sealing step, along an intermediate area adjacent to the free face 5 and lying between an adjoining face 5b equivalent to the face 5a mentioned previously, and the face of the product 1 parallel and opposite to this same face 5b ( figure 7b ).
  • the first flap 3 is then bent together with the second flap 4 in the same clockwise direction as previously, to the point at which the second flap 4 lies parallel to the formerly free face 5, between this same face 5 and the first flap 3 ( figure 7c ).
  • the outermost portions of the flaps 3 and 4 can be bent further in the same clockwise direction as previously, into a position parallel with the adjoining face 5b of the product 1 ( figure 7d ).
  • the flaps 3 and 4 can be sealed one to another not only at the step illustrated in figure 7b but also during the step illustrated in figure 7c or even the final step illustrated in figure 7d .
