Definitions

• confectionery products such as chocolate pralines, sugared almonds, etc.
• confectionery products such as chocolate pralines, sugared almonds, etc.
• an apparatus and a method for packaging items provide that the wrapping is pre-formed before the insertion of the item, so that the latter does not itself serve as the forming element of the wrapping (as in the case of wrapping by "bunch wrapping"), thereby preventing damage to the item due to handling.
• the two wheels carry a plurality of respective assemblies, provided with complementary forming members and forming seats, which are periodically brought into mutual engagement by the rotation of the wheels.
• the assemblies of the two wheels, oscillating around axes parallel to the rotation axes of the respective wheels, are configured so that the forming members (carried by one wheel) are periodically aligned with corresponding forming seats (carried by the other wheel). In this position, the aligned forming member and forming seat (between which a wrapping sheet is interposed) interpenetrate, drawing the wrapping sheet, which assumes a concave shape so as to define an open cavity into which the item can be inserted.
• a conveyor device may be provided, cooperating with the forming wheel to insert the item into a respective drawn wrapping sheet, and/or a sealing station, preferably arranged downstream of the forming wheel and configured to receive (preferably from said forming wheel) the wrapping sheets containing the respective items and to apply respective sealing elements to said sheets, which, together with the wrapping sheets, define respective closed cavities containing the items.
• the diagram in Figure 1 relates to a packaging apparatus according to the invention, which allows, for example, the production of a package C of the type illustrated by way of example in Figures 2 and 3 .
• Such a package C comprises an item P, specifically a praline of substantially spherical shape, wrapped in a packaging comprising a first and a second wrapping sheet 1, 2 and an optional cup-shaped container 3 (paper ramekin).
• the first wrapping sheet 1, which encloses the praline P, is shaped in an omega-like configuration, so as to define a cavity that includes the item and a terminal flange or rim 4;
• the second wrapping sheet 2 is in the form of a disc and is connected, for example, by sealing or gluing to the flange 4, thus forming a closed wrapping which, as shown in Figure 2 , is inserted into a cup-shaped container 3, whose bottom wall 5 is preferably adhered to the second wrapping sheet 2 in the form of a disc.
• the ⁇ -shaped configuration of the first sheet 1 which features a necking of the sheet and results in a narrowed opening and improved adhesion of the sheet to the external surface of the item, is purely optional.
• the packaging apparatus according to the invention may actually also be used to obtain packages wherein the first wrapping sheet is configured in a U-shape, wherein the head portion is complementary to the external surface of the item, whatever its shape may be, such as a hemispherical or flattened cap.
• the forming wheel continuously rotates around its own rotation axis, preferably horizontal, and comprises a plurality of forming assemblies 12, arranged near the peripheral edge of the wheel 10 and angularly spaced.
• Each forming assembly 12 comprises a forming seat 14, which forms the wrapping sheet into a configuration adapted to receive the item.
• a drawing wheel 16 is also present, continuously rotating around an axis parallel to the axis of rotation of the forming wheel 10, and comprising a plurality of peripheral drawing assemblies 18, articulated to the drawing wheel 16 in angularly spaced positions and oscillating about an axis parallel to the rotation axis of the drawing wheel 16.
• Each drawing assembly 18 comprises: a wrapping sheet holding member 20; and a punch drawing member 22. At least one of the holding member 20 of the wrapping sheet and the punch drawing member 22 is movable relative to the other, between: a passive configuration, wherein the punch drawing member 22 does not protrude radially from the holding member 20; and an active configuration, wherein the punch drawing member 22 protrudes radially from the holding member 20.
• a method for producing a wrapping defining a cavity suitable for containing an item may comprise the steps of providing an apparatus according to any of the embodiments described above; continuously feeding wrapping sheets to respective holding members 20 on the forming assemblies of the rotating forming wheel 10; in a condition wherein a forming seat 14, due to the rotation of the forming and drawing wheels 10, 16, is positioned facing and coaxial with a respective drawing member 22, transferring the wrapping sheet by relative movement of the forming seat 14 with respect to the drawing member 22, so that said drawing member 22 inserts into the forming seat 14 and draws the wrapping sheet.
