Abstract
A drive assembly (10) to drive packaging film for delivery to a packaging machine. The assembly (10) includes an elongated endless flexible belt (11) with a plurality of teeth (16) that are used to drive the belt (11). The teeth (16) are arranged in rows along the longitudinal edges of the belt (11). Between the rows of teeth (16) is a row of apertures (23) that communicates with a gallery (20).
Description
- The present invention relates to vacuum drive assemblies and more particularly but not exclusively to vacuum drive assemblies used to move tubular bag material to a packaging machine.
- Described in U.S. Pat. No. 4,663,917 is a packaging machine. The packaging machine receives tubular bag material into which product is delivered, with the packaging machine then transversely sealing and transversely cutting the tubular bag material to provide bags of product. The tubular bag material is moved to the packaging machine by a vacuum drive assembly (film drive unit). Vacuum belt drive assemblies (film drive assemblies) are disclosed in U.S. Pat. Nos. 7,472,528 and 4,910,943.
- Film drive units include a gallery past which a belt is driven. A vacuum is applied to apertures in the belt so that the packaging film is moved into contact with the belt so as to be gripped by the belt. Accordingly as the belt is driven, the tubular bag material is moved with the belt for delivery to the packaging machine.
- A disadvantage of known film drive units is that as the belts wear air leaks into the galleries thereby reducing the vacuum applied to the apertures in the belt. This has the disadvantage that the packaging film is not securely engaged with the result that bags may not be correctly fanned by the packaging machine.
- 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 vacuum drive assembly including:
-
- a gallery to which reduced air pressure is to be applied, the gallery having at least one aperture;
- an endless belt engaged with the gallery so as to be movable past the gallery in a predetermined direction, the belt having a longitudinally extending inner surface and a longitudinally extending outer surface between which apertures extend, the apertures being located at longitudinally spaced locations along the belt and are to be aligned with the gallery aperture so that reduced air pressure is applied to apertures of the belt aligned with the gallery aperture, a plurality of drive teeth located at spaced locations along the inner surface to be engaged by a drive sprocket that is to drive the belt in said direction, the projections being arranged in a pair of parallel rows, the rows each extending longitudinally of the belt but being transversely spaced so that the belt apertures are located between the rows; and wherein
- said gallery has a pair of elongated guide projections located between the teeth and engaged with the inner surface to aid in sealingly connecting the inner surface to the gallery, with the teeth also engaging the projections so that the belt is guided thereby in passing the gallery.
- Preferably, said gallery aperture is a slot extending in said direction.
- Preferably, the drive teeth are arranged in pairs, each pair consisting of a tooth from each of the rows, with teeth of each pair being transversely aligned, with a belt aperture located therebetween.
- A preferred form of the present invention will now be described by way of example with reference to the accompanying drawings wherein:
-
FIG. 1 is a schematic parts exploded isometric view of a vacuum drive belt and a vacuum gallery; -
FIG. 2 is a schematic isometric exploded view of portion of the belt ofFIG. 1 ; -
FIG. 3 is a schematic side elevation of the gallery and belt ofFIG. 1 with drive sprockets; -
FIG. 4 is a schematic sectioned side elevation of the gallery and belt as shown inFIG. 3 sectioned along the line 4-4; and -
FIG. 5 is a schematic enlarged view of portion of the gallery and belt as shown inFIG. 4 . - In the accompanying drawings there is schematically depicted a
vacuum drive assembly 10. Typically theassembly 10 would drive packaging film to be delivered to a packaging machine. As a particular example, twoassemblies 10 could be provided, with theassemblies 10 being located on opposite sides of tubular bag material being delivered to the packaging machine. - The
assembly 10 includes an elongated endlessflexible belt 11. Thebelt 11 includes a longitudinally extendingbody 12 having an outerlongitudinal surface 13 and a longitudinally extendinginner surface 14. Extending between thesurfaces belt apertures 15. - Extending inwardly from the
surface 14 is a plurality ofdrive teeth 16. Theteeth 16 are arranged in a pair ofrows 17 that extend longitudinally of the belt and are transversely spaced so as to be adjacent the edge portions of thebelt 11. Theteeth 16 are arranged in pairs that are transversely aligned across the belt so that anaperture 15 is located therebetween. - The
belt 11 is driven in apredetermined direction 18 by a pair of drive sprockets (rollers) 19. Each of thedrive sprockets 19 has a plurality of teeth that engage theteeth 16 so as to drive thebelt 11 in thedirection 18. - Engaged with the
belt 11 is agallery 20. Thegallery 20 includes an enclosedchamber 21 that via aduct 22 is connected to an air pump that reduces the air pressure in thechamber 21. - The
gallery 20 also has a longitudinally extending slot (aperture) 23 that extends in thedirection 18. Theaperture 23 is located so as to communicate with a selected number of theapertures 15 that are aligned with theaperture 23. - Located on either side of the
aperture 23 are longitudinally extendingguide projections 24. Theguide projections 24 are located between therows 17 so as to slidably engage theinternal surfaces 25 of theteeth 16 to guide thebelt 17 in its movement past thegallery 20. - Each of the
projections 24 has a generally planar longitudinally extendingsealing surface 26 that slidably engages theinner face 14 of thebelt 11 to sealingly connect thegallery 20 to thebelt 11. In this regard it should be appreciated that theaperture 23 is closed at its end extremities. - An advantage of the above described preferred embodiment is that the
surfaces 26 engage thesurface 14 so that a reduced air pressure is applied to theapertures 15. This arrangement is more tolerant to wear of thesurfaces inner surface 14.
Claims (4)
