Definitions
- the present invention relates to a method and machine for forming a sealed wrapping about an article, and to a package so formed.
- a sealed wrapping is formed about an article using a wrapping unit, which is fed with a succession of articles for wrapping, and with a continuous strip of normally airtight, heat-seal wrapping material.
- the sealed wrappings about the respective articles are normally formed by sealing the free longitudinal edges of the strip to define a tubular wrapping about the articles; transversely sealing the tubular wrapping at the ends of each article to form a respective "pillow pack"; and then separating the individual sealed wrappings.
- Figure 1 shows a schematic side view, with parts removed for clarity, of a machine in accordance with the present invention
- Figures 2 to 7 show successive steps in a method of forming a wrapping about an article in accordance with the present invention
- Figure 8 shows a schematic top plan view of parts of the Figure 1 machine in two different operating positions (indicated by a dash line and a continuous line);
- Figure 9 shows a schematic front view of parts of the Figure 1 machine in two different operating positions (indicated by a dash line and a continuous line);
- Figure 10 shows a schematic front view of parts of the Figure 1 machine
- Figure 11 shows a schematic side view of parts of the Figure 1 machine
- Figures 12 to 15 show schematically, with parts removed for clarity, a number of steps in forming the wrapping at part of the Figure 1 machine;
- Figure 16 shows the Figure 13 step from a different perspective
- Figure 17 shows a larger-scale portion of Figure 1.
- Number 1 in Figure 1 indicates as a whole a machine for forming a sealed wrapping 2 about a substantially parallelepiped-shaped article 3.
- article 3 comprises two opposite end walls 4 (only one shown in Figure 2); two opposite major lateral walls 5 (only one shown in Figure 2) crosswise (in particular, perpendicular) to end walls 4; and two opposite minor lateral walls 6 crosswise (in particular, perpendicular) to end walls 4 and major lateral walls 5.
- Machine 1 (in Figure 1) forms wrapping 2 from a sheet 7 of wrapping material in the steps shown in Figures 2 to 7, and as article 3 is fed along a path P.
- Sheet 7 is substantially rectangular and preferably made of airtight, heat-seal material.
- the wrapping 2 formed about article 3 substantially adheres to article 3, and comprises two major lateral portions 8; two minor lateral portions 9 crosswise to major lateral portions 8; and two end portions 10 crosswise to major lateral portions 8 and minor lateral portions 9.
- Wrapping 2 is sealed hermetically about article 3 along three sides by means of respective seals : one at a major lateral portion 8, and the other two at respective end portions 10.
- Wrapping 2 and article 3 together define a package that may either undergo further processing or be retailed as it is.
- major lateral portions 8 have a larger surface area than minor lateral portions 9.
- major lateral portions 8 have substantially the same surface area as minor lateral portions 9.
- machine 1 comprises a conveyor 11 for feeding article 3 to a folding device 12 comprising a push unit 13 and a wrapping wheel 14.
- Wrapping wheel 14 rotates in steps about an axis 15 perpendicular to the
- Figure 1 plane, and comprises a number of pockets 16 equally spaced about axis 15, and each for receiving a respective article 3 at a loading station 17, and conveying article 3 along a semicircular portion of path P to an unloading station 17'.
- Push unit 13 feeds article 3 in a direction A crosswise (in particular, perpendicular) to axis 15, so article 3 engages sheet 7 and is inserted together with sheet 7 inside respective pocket 16.
- sheet 7 is folded into a U, so that two pairs of flaps 18, at opposite ends of article 3, and a pair of flaps 19, 19' of sheet 7 project from the free sides of article 3.
- the flaps 18, 19 and 19' in each pair face each other and are substantially parallel ( Figure 2). Flaps 18 project, parallel to axis 15, from respective end walls 4 of article 3; flaps 19 and 19' project, crosswise to axis 15, from a minor lateral wall 6; and flap 19 is wider than flap 19'.
- Machine 1 ( Figures 1 and 17) also comprises a sealing device 20 for superimposing and sealing flaps 19 and 19' to form a substantially tubular partial wrapping 21 having two open ends 22, and a sealing flap 23 projecting outwards crosswise to partial wrapping 21 (Figure 3).
- Partial wrapping 21 comprises major and minor lateral portions 8 and 9, which are connected to one another by respective lateral edges 24; and sealing flap 23 projects outwards from, and extends along, a respective lateral edge 24.
- Sealing device 20 ( Figures 1 and 17) comprises a substantially fixed member 25 at loading station 17; and a member 26 which is movable, in a direction crosswise to direction A, between an open position (shown by the continuous line in Figure 17) and a closed position (shown by the dash line in Figure 17).
- At least one of members 25, 26 is a heat-seal member (i.e. for transferring heat to sheet 7 to seal flaps 19 and 19').
- both members 25, 26 are heat-seal members.
- Sealing device 20 also comprises a heat-seal member 27, downstream from loading station 17 and upstream from unloading station 17', for preferably fluidtight sealing flaps 19 and 19' to each other to form sealing flap 23.
- member 27 oscillates about a respective axis (not shown) substantially parallel to axis 15, to contact flaps 19 and 19' when wheel 14 is stationary.
- machine 1 comprises a number of members 27 arranged successively between loading station 17 and unloading station 17'.
- machine 1 has no member 27, and flaps 19 and 19' are sealed to each other by members 25 and 26 at loading station 17.
- Machine 1 also comprises a folding device 28 for folding sealing flap 23 onto a major lateral portion 8.
- Folding device 28 comprises a known fixed plate (not shown) located along the periphery of wheel 14 to fold sealing flap 23 crosswise (in particular, perpendicularly) to respective major lateral portion 8; and a pusher 29 to feed article 3 in a substantially radial direction with respect to axis 15, so sealing flap 23 is folded onto respective major lateral portion 8 by contrast with a fixed folding member 30.
- Pusher 29 is located at unloading station 17'; and folding device 28 also comprises a heating head 31 located at a stabilizing station 32 along path P, and which is movable crosswise to path P to engage and stabilize sealing flap 23 on major lateral portion 8.
- Machine 1 also comprises a conveyor 33 for feeding article 3 in direction A along a substantially straight portion of path P from stabilizing station 32; through a closing station 34 where open ends 22 of partial wrapping 21 are closed to form sealing flaps 35; to a folding station 36 where sealing flaps 35 are folded.
- Conveyor 33 comprises a belt (shown partly in Figure 1) having a work branch 37 and looped about two known pulleys (not shown) rotating about respective axes parallel to axis 15.
- Articles 3 are positioned on conveyor 33 with open ends 22, sealing flap 23, and minor lateral portions 9 crosswise to direction A.
- a retractor 38 deforms a respective open end 22 of partial wrapping 21 to form two facing flaps, and a sealing device 39 grips and preferably fluidtight seals the facing flaps to form respective closed end portion 10 and relative sealing flap 35, which projects from and defines a seal of end portion 10.
- Retractor 38 comprises two arms 40 movable between a closed rest position (shown by the dash line in Figure 8), and an open taut position (shown by the continuous line in Figure 8).
- Sealing device 39 comprises a gripper unit in turn comprising two heat-seal jaws 41 movable between an open rest position (shown by the dash line in Figure 8), and a closed sealing position (shown by the continuous line in Figure 8).
- machine 1 also comprises a folding device 42 at folding station 36, to fold sealing flaps 35 onto respective end portions 10.
- Folding device 42 comprises a conveyor 43 for feeding article 3 along a substantially straight portion of path P; and two substantially fixed plates 44 (only one shown) located on opposite sides of path P to fold sealing flaps 35 onto respective end portions 10 (as shown particularly in Figures 12, 13 and 16).
- conveyor 43 comprises an elevator 45 for moving article 3 crosswise to major lateral portions 8 in a direction, in particular a substantially vertical direction, crosswise to direction A.
- sealing flaps 35 are of such a length that, once folded, each extends up to a respective edge 24' connecting respective end portion
- sealing flaps 35 are shorter and fall short of respective edges
- each of sealing flaps 35 comprises two tabs 46 projecting from opposite sides of respective end portion 10.
- Folding device 42 also comprises four flip-over rails 47, each designed so that each tab, as it slides along respective rail 47, is folded roughly 180° onto respective end portion 10 (as shown particularly in the Figure 13 to 15 sequence). More specifically, each rail 47 comprises a first portion 48 for folding respective tab 46 roughly 90° into a position substantially perpendicular to respective end portion 10 ( Figure 14); and a second portion 49, after portion 48, for folding tab 46 onto end portion 10 ( Figure 15).
- Machine 1 also comprises a conveyor 50, downstream from folding device
- retractors 38 deform open ends 22; sealing devices 39 form end portions 10 and sealing flaps 35; and conveyor 33 feeds article 3 to folding device 42.
- conveyor 50 feeds article 3 between two known heating plates (not shown) to stabilize sealing flaps 35 and tabs 46 on respective end portions 10 and so obtain package 2.
- sealing flap 23 on major lateral portion 8 provides for particularly good sealing of open ends 22. If sealing flap 23 were to be located on one of minor lateral portions 9, deformation by retractor 38 and sealing by sealing device 39 would be more problematic, on account of the greater thickness of the wrapping material involved, and there would be more risk of sealing flap 23 becoming detached from respective minor lateral portion 9 (especially when deforming open ends 22).
- rails 47 for folding tabs 46 roughly 180° are particularly advantageous in terms of faster production and compactness.
