Description

PACKAGING MACHINE FOR FORMING ULTI-COMPARTMENTAL PACKS
Field of the Invention
The present invention relates to packaging machines including packaging machines for use in producing high integrity packaging used, for example, for medical and pharmaceutical goods, and for general packing of foods and consumer goods.
Background to the Invention
Packaging used to protect certain medical products, for example, syringes, dressings or replacement organs such as skin, during transit and storage, needs to be of sufficient integrity in order that the contents are maintained in a locally sterile environment.
The nature of the contents of the packaging and their use, means that a zero percent failure rate of the packaging must be achieved. Furthermore, the process by which the packaging is formed must also be capable of full validation. Quality control to ensure that this standard is achieved cannot be carried out by the use of a destructive sampling procedure. The process therefore is carried out using such strict control of the values of a number of parameters, the values for the parameters being known to give a package of a suitable quality.
The need for the parameters to be closely monitored and maintained within strict limits means that the production of the packages is often slow.
Prior art machines suffer from the drawback that when production needs to be switched from one type and/or size of packaging to another, converting the machine appropriately is time consuming and often labour intensive. Furthermore, the act of changing over can affect the consistency and accuracy of the seal
One such prior art machine available for packaging goods is that marketed by the present Applicant under the designation "MT 2500" Using this machine, a base material having a plurality of compartments is passed to a loading station where product is loaded into individual pre-formed compartments From the loading station, the base material is passed to a sealing station where an upper layer is then sealed to the base material over the product-bearing compartments by means of a single sealing platen Changing the base material configuration and the pattern used for applying adhesives for the sealing platen is slow, with a resulting loss in production time Tooling changes associated with this pattern are also expensive
It is an object of the present invention to provide a packaging machine which alleviates the above disadvantages and which allows the sealing station replacement to be eliminated for example when change-over from one product to another is required
It is a further object of the invention to provide a process for sealing a product in multi-compartmental packs which alleviates the above problems

control means for controlling the speed, position and seal parameters of the packaging apparatus, said means controlling a further seal mechanism or mechanisms to seal the sealing material to the packaging material to form compartments within the peripheral seal of the packaging
Advantageously, the packaging apparatus comprises at least one further seal member which seals in a direction which is perpendicular to the feed direction of the packaging material
The further seal member is preferably moveable across the surface of the pack to produce a number of spaced seals within a pack
The position of the seals is conveniently controlled using control means which control the motion of the packaging relative to the sealing members The control means controlling the motion of the packaging is conveniently a servomechanism

Detailed Description of the Invention
In a known apparatus, such as that shown in Figure 1. a base-material 10 is unfurled from a mill roll 1 1 From the mill roll 1 1, the base-material 10 is passed through a thermoforming station 12 where compartments adapted to receive products are formed in the base-material 10 by a combination of the use of a forming tool (not illustrated) and pressure differential across the two surfaces of the base-material 10.
The base-material 10 is passed to a product loading area 13, where the product is placed into the compartments in the base-material 10 The upper top-material 14 is unfurled from the upper mill roll 15 and is guided over guide rollers 17 and 18 so that the upper top-material 14 flows co-directionally just above the base- material 10
The base-material 10 and the upper top-material 14 are sealed together at the sealing station 19 The sealing station 19 comprises a bottom die 20 which is guided on tooling grade pillars and bushes (not illustrated) to ensure correct alignment The heated sealing platen 21 is pressed down onto the upper surface of the upper top-material 14, the heat from the sealing platen 21 being sufficient to seal the upper top-material 14 to the base-material 10 The bottom die 20 and the sealing platen 21 are so configured that both the seals parallel and perpendicular to the longitudinal axis of the base-material 10 are applied to complete the sealing of an individual compartment The sealed packaging is passed to the knife station 22 and the slitting station 23 to cut the assembled products into the final individual packs
When production needs to be switched to a different product having a different individual compartment and pack size, the forming tool, sealing platen 21 , and bottom die 20 need to be replaced with ones having the appropriate shape and size Although replacement of the forming tool is normally a simple and quick operation, replacement of the sealing platen is not Moreover, specific sealing platens need to be formed for each product
With reference to the drawings embodying the invention, the first embodiment of the packaging machine, generally referenced 30, as illustrated in Figure 2, includes fhermo-forming members, for forming the base material 3 1 which thermoforming members are substantially identical to those known in the prior art and as exemplified in the machine of Figure 1
Also substantially identical is the mechanism by which the thus formed base- material 31 is brought together with the upper top-material 32 In the machine 30 however, the sealing station 33 seals the upper top-material 32 to the base- material 31 simply about the periphery of the thermo-formed material as illustrated in Figure 3 The seal, shown as the shaded area 50 in Figure 3 isolates the products in compartments 51 from the environment although not from one another This isolation allows the control maintained over contact between the products in the compartments 5 1 and the environment to be relaxed for the subsequent steps and allows savings in terms of instrumentation and running costs, to be realised
Once the peripheral seal 50 has been formed, the sealed product passes to a secondary sealing region, the secondary sealing station 34 A sealing bar (not illustrated), orientated perpendicularly to the flow, indicated by the arrow in Figure 3, on the packaging material, seals by the use of heat and pressure the upper-material 32 to the base-material 31 along seal 52 Once the seal 52 has been formed, the sealing bar is lifted from the upper top-material 32 and the packaging material moved via a servomechanism to ensure that the sealing bar is positioned over the next area to be sealed Again the sealing bar is lowered onto the upper top-material 32 and forms a further seal This process is repeated until all the required individual seals have been formed The individual compartments are thereby isolated and the products contained therein sealed in
The packs are then passed to the knife station 35 and the individual compartments separated from one another
In use the base material 31 having pre-formed compartments therein is presented to a product loading area 13, where the product is loaded into said base material ' 3 1 Upper top material 32 is then moved on to the base material 31 such that the upper top-material 32 overlays the base material 3 1 The upper top material 32 is sealed to the base material 3 1 about their periphery A sealing bar is then used to form further seals between the upper top-material 32 and the base material 31 to subdivide the pack into compartments
According to a further embodiment of the method, further sub-dividing seals may be applied by the application of a further sealing member which applies seals which are substantially perpendicular to those applied by the first sealing bar
Advantageously heat is supplied to seal the first packaging material to the second packaging material
In a further embodiment of a packaging apparatus, generally referenced 60, according to the invention, shown in Figure 4, a further series of seals, perpendicular to those illustrated in Figure 2 are introduced at a third sealing station 61 Sealing is achieved in a manner corresponding to that illustrated in Figure 2 A second sealing bar (not illustrated), oriented in the direction of flow (indicated by the arrow in Figure 5) of the packaging material is pressed against the upper top-material 62 The upper top-material 62 is sealed to the base- material 63 by heat and pressure applied by the sealing bar The sealing bar is lifted from the formed seal, and the packaging material, under the control of the servomechanism moved by a pre-set amount A further seal 53 is formed between the upper top-material 62 and the base-material 63 As shown in Figure 5, repeated sealing by the sealing bars forms a matrix-like series of seals to form individual compartments containing the product
The formed products are then passed to a knife station 64 and a slitting station 65 to cut the product into individual packs
In a yet further embodiment of the invention, relative motion between the packaging material and the or each sealing bar is achieved by controlled motion of the sealing bar relative to the packaging material The motion can be controlled by a servomechanism
It will of course be recognised that individual seals parallel to the packaging material can be formed first, followed by any perpendicularly oriented seals, where these are required As an alternative to a sealing bar, a sealing roller or wheel could be used When such a roller is used, sealing is achieved by apph ing pressure to the roller to maintain it in contact with the packaging material The roller is then moved linearly along the region to be sealed
In a yet further embodiment of the invention (not illustrated), the sealing bar may be rotatable in the plane of the packaging material. In this embodiment once the sealing bar has produced a number of parallel compartmental seals it may be rotated through 90° to allow a further series of seals to be provided perpendicular to the first set of seals
Where the seal is produced thermally, the sealing member has means to maintain the surface in contact with the packaging material at the necessary elevated temperature It also has means to record the temperature which is monitored Should the temperature move outside pre-set values then the packaging process is temporarily halted to allow the correct temperature to be reached Once this temperature has been reached then the process can be restarted
Using the machine described above a 400 x 400mm pack is sealed at sealing station 33 By use of the sealing bar in the second sealing station 34, the initially sealed pack is subdivided into two 400 x 200mm packs By suitable setting of the servomechanism driving the packaging material the 400 x 400mm pack described above could easily be subdivided into three 400 x 133mm packs, four 400 x 100mm packs or five 400 x 80mm packs etc. The further sealing bar oriented perpendicularly to the first sealing bar in the secondary sealing station could then subdivide these packs further.
It will of course be understood that the invention is not limited to the specific details described herein, which are given by way of example only, and that various modifications and alterations are possible within the scope of the invention.
