Definitions

  • the present invention relates to a device for transferring a product and partially covering it with a packaging sheet.
  • the product is made translate along a conveyance line until it encounters (with its foremost surface with respect to the direction of conveyance) a wrapping sheet. Once the product has encountered the sheet, a further translation of the product determines the entry of its foremost surface, and of the sheet abutting on it, into a hopper which folds the remaining portions of the sheet onto the faces of the product that are contiguous with the foremost surface).
  • the sheet is constituted by a permanently deformable material (such as for example sheets of aluminum or sheets that comprise such material), this will settle on the faces of the product in a stable manner, when passing through the hopper, ready for subsequent operations for folding and/or heat-sealing and/or adhesive bonding. But if the sheet comprises materials that exhibit an elastic return after the folding imposed by the hopper, this will complicate the successive steps of packaging the product, and may even compromise the quality of the corresponding results.
  • a permanently deformable material such as for example sheets of aluminum or sheets that comprise such material
  • materials that have an elastic return may also result in relative movements between the product and the sheet that may impede (or in any case complicate) the subsequent packaging operations.
  • the aim of the present invention is to solve the above-mentioned drawbacks, by providing a device for transferring a product and partially covering it with a packaging sheet that ensures the stable juxtapositioning of the flaps of the sheet against respective faces of the product.
  • an object of the invention is to provide a device for transferring a product and partially covering it with a packaging sheet that prevents relative movements between the product and the sheet.
  • Another object of the invention is to provide a device for transferring a product and partially covering it with a packaging sheet that prevents the sheet from being damaged during the passage through the hopper.
  • Another object of the invention is to provide a device for transferring a product and partially covering it with a packaging sheet that prevents the formation of wrinkles on the sheet during the passage through the hopper.
  • Another object of the invention is to provide a device for transferring a product and partially covering it with a packaging sheet that ensures an arrangement of the sheet on the product that is ideal for the subsequent operations to complete the packaging.
  • Another object of the present invention is to provide a device for transferring a product and partially covering it with a packaging sheet which is of low cost, easily and practically implemented, and safe in use.
  • a device for transferring a product and partially covering it with a packaging sheet of the type arranged so as to operate on a conveyance line for products and comprising an assembly for supplying packaging sheets and a folding hopper for folding at least one said sheet onto at least one corresponding product, characterized in that it comprises grip means which are configured to clamp said product and said sheet which is partially juxtaposed against a face thereof, said grip means being functionally associated with respective actuators for transferring the product and the sheet clamped together from a first position, upstream of said hopper, to a second position, downstream of said hopper, said sheet, in said second position, being partially juxtaposed against at least two faces of said product.
  • the reference numeral 1 generally designates a device for transferring a product P and partially covering it with a packaging sheet A.
  • the device 1 according to the invention can conveniently be arranged to operate on a conveyance line of products P.
  • the device 1 can advantageously comprise an assembly for supplying packaging sheets A (the assembly can be an integral part of the device 1 or be associated with it in any manner) and a folding hopper 2 for folding at least one sheet A onto at least one corresponding product P.
  • the folding hopper 2 is substantially of the type known in the packaging sector: the product P, advancing toward (and through) the hopper 2, abuts against the sheet A and pushes it into the hopper 2.
  • the passage through the hopper 2 (which will have an opening with shape and dimensions complementary to those of the product P, optionally increased in order to allow the passage also of the sheet A overlaid thereon and suitable play) will result in the sheet A being placed in juxtaposition against faces of the product P, thus constituting the first operation to cover the product P with the sheet A that takes place in the process of packaging it.
  • the device 1 comprises grip means 3 which are configured to clamp a product P and the sheet A which is partially juxtaposed against a face P 1 thereof.
  • the grip means 3 are profitably functionally associated with respective actuators for transferring the product P and the sheet A clamped together from a first position, upstream of the hopper 2, to a second position, downstream of said hopper 2.
  • the sheet in this second position (shown by way of non-limiting example in the accompanying Figure 4 ), is partially juxtaposed against at least two faces P 1 , P 2 and P 3 of the product P.
  • the grip means 3 can advantageously comprise a pusher 4, which is adapted to abut against a face P 4 of the product P which is opposite to the face P 1 that is proximate to the wrapping sheet A.
  • the pusher 4 will advantageously be actuated by a respective first controlled actuator, along a preset stroke, of which a section coincides substantially with the path traveled by the product P between the conveyance line and a delivery station 5, arranged downstream of the hopper 2, at the aforementioned second position.
  • the grip means 3 can conveniently comprise a contrast pusher 6, which is adapted to abut against the face P 1 of the product P that is proximate to the wrapping sheet A.
  • This contrast pusher 6 will advantageously be actuated by a respective second controlled actuator, along a preset stroke, of which a section coincides substantially with the path traveled by the product P between the conveyance line and the delivery station 5, arranged downstream of the hopper 2 at the aforementioned second position.
  • the product P will pass through the hopper 2 while it is clamped between the pusher (which abuts against its face P 4 ) and the contrast pusher 6 (which abuts against its face P 1 ): it should be noted that the sheet A is interposed between the face P 1 and the contrast pusher 6.
  • the grip means 3 pushher 4 and contrast pusher 6
  • the delivery station 5 can conveniently comprise clamping means which are configured to keep the sheet A juxtaposed against respective faces P 1 , P 2 and P 3 of the product P.
  • the clamping means can positively comprise at least one jaw 7 for clamping the mutually opposite faces P 2 and P 3 of the product P that are contiguous with the faces P 1 and P 4 against which the grip means 3 abut (during the transfer of the product P and the sheet A from the first position to the aforementioned second position).
  • the at least one jaw 7 can usefully comprise a terminal tooth 7a protruding toward the face P 4 of the product P against which the pusher 4 was resting.
  • the tooth 7a will therefore be conveniently configured to force a portion of the sheet A onto the face P 4 against which the pusher 4 is placed, even after the respective distancing of the pusher from such face P 4 .
  • the pusher 4 can advantageously comprise a contoured lever 8 with an initial end 9 which is adapted to abut against a respective face P 4 of the product P.
  • the lever 8 will be functionally associated with at least one movement element by way of at least one pusher linkage 10, 11 hinged thereto.
  • the pusher linkages 10, 11 can profitably be two in number: a first pusher linkage 10 will conveniently be hinged substantially at a terminal end of the lever 8 and keyed to a respective controlled motor; a second pusher linkage 11 will instead advantageously be hinged at a central part of the lever 8, and an articulated pusher arm 12 will be interposed between the second pusher linkage 11 and a respective controlled motor.
  • the contrast pusher 6 can also positively comprise a contoured bar 13 with an initial end 14 which is adapted to abut against a respective face P 1 of the product P.
  • the bar 13 will, in turn, be functionally associated with at least one movement element by way of at least one contrast pusher linkage 15, 16 which is hinged thereto.
  • the contrast pusher linkages 15, 16 will preferably be two in number: a first contrast pusher linkage 15 will efficiently be hinged substantially at a terminal end of the bar 13 and keyed to a respective controlled motor, while a second contrast pusher linkage 16 will be hinged at a central part of the bar 13. An articulated contrast pusher arm 17 will usefully be interposed between the second contrast pusher linkage 16 and a respective controlled motor.
  • the device 1 ensures that the correct relative positioning between the product P and the wrapping sheet A obtained in the hopper 2 (that draws the wrapping sheet A) is maintained right up until arrival inside the delivery station 5.
  • the two independent kinetic mechanisms (the lever 8, the linkages 10 and 11, the arm 12 and respective controlled motors for the pusher 4 and the bar, the linkages 15 and 16, the arm 17 and respective controlled motors for the contrast pusher 6) move in a complementary manner, first by bringing the product P (with its face P 1 ) into contact with the wrapping sheet A in their correct relative position (as illustrated by way of non-limiting example in Figure 2 ), and then clamping them respectively (as illustrated by way of non-limiting example in Figure 3 ). Once the relative engagement of the sheet A on the product P is achieved, the sheet A can conveniently be cut to the desired length.
  • the pusher 4 and the contrast pusher 6 move in perfect synchrony, transporting the assembly constituted by the product P and the sheet A through the drawing hopper 2 which will draw the covering sheet A so as to conveniently cover the product P on three sides (so covering the faces P 1 , P 2 and P 3 , as shown by way of non-limiting example in the accompanying Figure 4 ).
  • the at least one jaw 7 can be closed, clamping them; only after this closure the pusher 4 and the contrast pusher 6 will abandon the assembly constituted by the product P and the sheet A, thus effecting a proper handover to the next stage (the assembly of product P and sheet A is never left and this constitutes an assurance of the correct positioning of the sheet A with respect to the product P).
  • the adoption of the pusher 4 and the contrast pusher 6 brings the following advantages:
  • the present invention solves the above-mentioned problems, by providing a device 1 for transferring a product P and partially covering it with a packaging sheet A that ensures the stable juxtapositioning of the flaps of the sheet A against respective faces P 1 , P 2 and P 3 of the product P.
  • the device 1 according to the invention prevents relative movements between the product P and the sheet A.
  • the device 1 prevents the sheet A from becoming damaged during the passage through the hopper 2.
  • the device 1 prevents the formation of wrinkles on the sheet A during the passage through the hopper 2.
  • the device 1 according to the invention ensures an arrangement of the sheet A on the product P that is ideal for the subsequent operations to complete the packaging.
  • the device 1 according to the invention is easily and practically implemented and is of low cost: such characteristics make the device 1 according to the invention an innovation that is safe in use.
  • the materials employed, as well as the dimensions, may be any according to requirements and to the state of the art.
