Definitions
- the present invention relates to a method of packaging a product in discrete units.
- a tubular bag material In the packaging of product which comprises a plurality of discrete units, it is common for a tubular bag material to be formed from sheet material, and the tubular bag material delivered to a filling head whereat the product is delivered to the interior of the tube material.
- the material is subsequently sealed at spaced intervals and discrete bags severed from the tubular material.
- the sheet material generally comprises a plastic film which is sealed by heat or other means to form the tubular material.
- the tube material is also sealed transverse of its longitudinal direction of extension, so as to form the discrete bag. This sealed area is also severed by a knife so that the discrete bags are separated from the tubular material.
- the speed of the film through the machine determines the period of time to which the plastic film is exposed to the sealing heads which form the discrete bags.
- the temperature of the sealing heads must be adjusted to match the speed of the film material so that proper sealing does take place.
- the invention relates a method of driving film material through a packaging machine which has means to supply said film material, means to bring the film into a tubular form and sealing means to engage intermittently and to seal transversely the tubular film to form discrete bags.
- a method is known for instance from GB-A-2056940.
- the method is characterised by driving the material continuously at a first velocity while the sealing means engage the film material and at another velocity independent of the first velocity to determine the production rate of the machine.
- the machine also comprises a pair of endless belts having generally parallel co-extensive portions engaging said bag material to move same through said machine, motor means drivingly attached to said endless belts to drive same so that said belt portions have the same velocities and are moving in the same direction, and control means to control said motor means to govern the speed of said endless belts so that said sealing means is engaged with said bag material for a predetermined fixed period of time.
- FIG. 1 there is schematically depicted a drive unit 10 of a packaging machine which unit 10 is operable on a continuous basis.
- the packaging machine includes means to deliver sheet film material 11 to former 12 which forms the sheet material 11 into a tubular configuration.
- the tubular material is moved through the packaging machine by a pair of endless belts 13 which are provided with a plurality of holes 14 which face the tubular material.
- Located at the rear of the belt 13 is a plennum chamber 15 to which there is delivered a vacuum by means of conduit 16.
- the chamber 15 is open to an inside surface of the belt 13 so that the vacuum is applied to the holes 14 so that the tubular material is held against the belts 13.
- the belts 13 pass around rollers 17 of which two at least are driven.
- rollers 17 could each be driven by a shaft 18 coupled to a worm drive unit 19.
- the drive unit 19 would be connected to an electric motor which would be controlled to vary the peripheral speed of the belt 13.
- the motor could be a stepping, servo, computer controlled or any other motor having suitable control characteristics.
- the speed of the belt 13 would be controlled so that the tubular material delivered to the sealing heads would be travelling at a predetermined velocity so that the sealing heads are in contact with the tubular material for a set period of time. Thereafter, the motors would increase the speed of the endless belts 13 to increase the production rate of the packaging machine or alternatively decrease the speed of the tubular material, to achieve a decrease in the output of the packaging machine. Accordingly, the speed of the endless belt 13 may be adjusted to accommodate different products and/or sheet packaging material 11.
- FIG 2 there is schematically depicted three graphs which illustrate typical velocity profiles of the endless belts 13.
- the period of time D is the period during which the sealing heads are in contact with the tubular film material. Thereafter, the speed of the film is decreased and subsequently increased.
- the period of time D is the same, and the speed of the film is only slightly decreased.
- the period of the interval D is the same with the speed of the film increased after the period D to increase the production rate of the machine. With the period of time D constant, the velocity is also held constant for that time.
- a drive roller 21 is provided around which the film 11 passes.
- the film 11 also passes around an idler roller 23 and is sandwiched between the film drive roller 21 and a further idler roller 22.
- the roller 21 is attached to a servo motor 22 which determines the velocity of the film 11 as required.
- the servo motor 22 could be driven so as to provide the velocity profile of any one of the velocity profiles depicted in Figure 2.
- FIG 4 wherein the tubular material 24 is more fully depicted relative to a backing bar 20 as provided in Figures 1 and 3.
- the tubular material 24 overlaps at portions 25, which portions 25, are heat sealed via heat provided by the sealing head 26.
- the sealing head 26 is located within the chamber 15.
- This particular arrangement in respect of sealingly tubular material 24 is particularly different from the prior art in that the overlap portions 25 are engaged by the belt 13 as well as the opposite side of the tubular material 24. Conventionally, the other two sides of the tubular material are generally engaged. This provides specific advantages in respect of the continuous sealing of the tubular material 24, which is driven in a continuous manner past the heating head 26.
