Abstract
A packaging machine former apparatus 10 through which a film 11 passes to be
formed into a tube 12. The apparatus 10 includes a shoulder 15 over which the film 11
passes, the shoulder 15 including an approach member 16 that leads to a crown 17. The
member 16 includes a passage 20 terminating in an aperture 21 to which a gas under
pressure is delivered so as to create an "air cushion" over which the film passes, thereby
aids in movement of the film 11 over the surface 18 of the approach member 16.
Description
- The present invention relates to packaging machines and more particularly to former shoulders which receive film from a roll to transform the film into a tubular configuration for delivery to a machine which forms discrete packages containing product.
- Packaging machines such as those described in USA Patents 4663917, 4423858, 4391081, 3070931 and 3850780 employ formers which transform plastic film (strip) into a tubular configuration. The film is pulled through the former by means of a film drive unit. Typically the film drive unit will engage the tubular material by means of rollers and belts such as that discussed in USA Patent 4910943. It is also known to move the tubular bag material through the packaging machines by means of engagement with the jaws of the packaging machine.
- A former includes a forming shoulder over which the film passes. Problems are often encountered with this relative movement which can result in a variation in the force required to move the film over and through the former. Preferably the force required is constant and is not excessive. These problems are exacerbated in the case of heavy gauge film as well as film that may be relatively stiff. Humidity and static charge also influence the force required to be applied to the film.
- A further problem to the above is that frequently formers will smudge any printed material applied to the film.
- It is the object of the present invention to overcome or substantially ameliorate at least one of the above disadvantages.
- There is disclosed herein a shoulder for a packaging machine former, said shoulder including:
- a crown over which film passes to be arranged in a tubular configuration; and
- an approached member extending to said crown and having a surface past which the film moves in approaching said crown, said member having a passage extending to said surface through which a gas under pressure is delivered to deliver said gas to an area between said surface and said film.
-
- Preferably the said passage terminates with an aperture located generally centrally in said surface.
- A one preferred form there is a plurality of said passages extending to said surface through which said gas is delivered so that said gas is delivered to an area between said surface and said film.
- Preferably said shoulder further includes a valve to deliver said gas to said passage, said valve being adapted to govern the pressure of said gas delivered to said surface.
- A preferred form of the present invention will now be described by way of example with reference to the accompanying drawings wherein:
- Figure 1 is a schematic perspective view of a former apparatus of a packaging machine;
- Figure 2 is a schematic perspective view of film passing through the apparatus of Figure 1;
- Figure 3 is a section schematic side elevation of the apparatus and film of Figures 1 and 2;
- Figure 4 is a further schematic perspective view of the film and apparatus of Figures 1 and 2;
- Figure 5 is a further schematic perspective view of the apparatus and film of Figures 1 and 2; and
- Figure 6 schematically depicts a modification of the apparatus of Figures 1 to 5.
-
- In the accompanying drawings there is schematically depicted a
former apparatus 10 through which a web offilm 11 passes to be formed into atube 12. Thetube 12 passes through a packaging machine and receives a product which is to be packaged by the packaging machine. The product to be packaged is delivered to theupper aperture 13 of thetube 12, with thetube 12 being subsequently scaled along the back seam and at spaced locations to form discrete packages. - The
apparatus 10 includes abase 14 which supports ashoulder 15 over which thefilm 11 passes. Theshoulder 15 includes anapproach member 16 which leads to acrown 17 over which thefilm 11 passes to be configured to form thetube 12. Themember 16 has anupper surface 18 past which thefilm 11 moves in its passage to thecrown 17. - The
film 11 is removed from a roll and first engages aroller 19 before delivery to thesurface 18, - The
member 16 is provided with apassage 20 terminating at its end with a generally centrally locatedaperture 21. Theaperture 21 is in thesurface 18. Extending from thepassage 20 is aduct 22 communicating with anairflow control valve 23. Thevalve 23 receives a gas (typically air) under pressure. Thevalve 23 governs delivery of air to thepassage 20 and therefore theaperture 21. Air leaving theaperture 21 enters anarea 24 between thesurface 18 andfilm 11. This aids movement of thefilm 11 over thesurface 18 by creating an "air cushion" over which thefilm 11 passes. This reduces frictional engagement between thesurface 18 and thefilm 11. As best seen in Figures 4 and 5, the air escapes laterally relative to thelongitudinal direction 25 of movement of thefilm 11. - If so required, there may be a plurality of the
passages 20 and associatedapertures 21, with the apertures distributed over thesurface 18. - Extending from the
valve 23 is aduct 26 which attaches theapparatus 10 to a supply of gas under pressure. - In respect of the delivery of gas to the
valve 23, it should be appreciated that the flow of gas could be pulsed if so required. Still further, the gas could be heated or chilled to increase or decrease the stiffness of thefilm 11. Still further, heating of thefilm 11 may aid in the drying of ink. - In a further embodiment (as shown in Figure 6), one or
more apertures 21 are formed in thesurface 18, each with an associatedpassage 20 extending from theduct 22
