Detailed Description of the Invention
The invention will be more clearly understood by the following description of an embodiment thereof, given by way of example only, with reference to the accompanying drawing which is a schematic illustration of pouch manufacturing apparatus according to the invention.
Referring to the drawings there is illustrated pouch manufacturing apparatus according to the invention indicated generally by the reference numeral 1. The apparatus 1 has a ground engaging support frame which has been omitted from the drawing for the sake of clarity on which the various components of the apparatus to be described later are mounted.
A pair of supply reel supports, namely an upper supply reel support 10 and a lower supply reel support 11 are mounted on the support frame for rotatably supporting supply reels 12,13 carrying webs 14,115 of a front panel forming material and a rear panel forming material respectively. In this casethe front panel web 14 is of clear thermo-plastics material and the rear panel web 15 is of a paper material to which the web 14 can be joined.
A complementary pair of draw rollers 20,21 mounted on the support frame are operable to pull both webs 14,15 from their associated supply reels 12,13, at the same time overlapping the webs 14,15 prior to delivery of the overlapped webs to a sealing station 22, described later. A second set of draw rollers is mounted downstream of the sealing station 22 and is drivably linked to the first draw rollers.
Each web 14,15 as it is drawn off its associated reel 12,13 is delivered through a web cleaner 26,27 which essentially comprises a pair of rollers between which the web 14,15 is passed, the rollers having a tacky surface to pick up any dirt and loose material from the surface of the web 14,15.
Downstream of each web cleaner 26,27 the web 14,15 passes through a web tensioner 30,31. Each web tensioner comprises two associated sets of rollers, namely an upper fixed roller set having a number of spaced-apart in-line rollers 32 and a complementary lower movable roller set comprising a number of rollers 33 mounted between a pair of spaced-apart pivot arms 34 on the support frame. As shown in the drawing the web 14,15 is alternately wound about upper rollers 32 and lower rollers 33 to define a tortuous path about which the web 14,15 is drawn.
The movable rollers 33 are mounted on the pivot arms 34 which are pivotally mounted on a carrier on the support frame for pivotal movement towards and away from the fixed rollers 32 to alter the length of the tortuous path. The draw rollers 20,21 are operable to incrementally feed the webs 14,15 to the sealing station 22.
When the draw rollers 20,21 are engaged they pull the webs 14,15 from the tensioners 30,31, the arms 34 pivoting upwardly to release the webs 14,15 on demand to the draw rollers 20,21. When the draw rollers 20,21 are stopped in between feeding steps each pair of arms 34 drops downwardly moving the rollers 33 away from the fixed rollers 32 to store up the web prior to the next delivery step.
In this way the webs 14,15 can be-fed continuously from the supply reels 12,13 for a smooth delivery of the webs 14,15 from the supply reels 12,13 and through the tensioners 30,31. It will be noted that the arms 34 carrying the movable rollers -33 may be biased away from the fixed rollers 32 by any suitable means to apply a desired tension to the webs 14,15.
Each of the web tensioners 30,31 is mounted on a carriage which is laterally movable on the support frame for independent sideways movement of the webs. A web edge sensor 40 is provid ed for each web 14,15. Each web sensor 40 is connected to a controller for the web tensioner carriage for adjustment of the carriage position in response to the sensed web edge positions for maintaining the web edge positions in a preset desired alignment as the webs 14,15 are delivered through the apparatus. This way the webs 14,15 are maintained accurately in alignment and are delivered through the draw rollers 20,21 in accurate overlapping alignment. The webs are aligned relative to the sealing station 22 to ensure accurate sealing of the webs.
The overlapped aligned pair of webs are delivered to the sealing station 22. The sealing station 22 has a die 45 and associated anvil plate 46 on an upper surface of which is located a silicone mat 47. The webs are delivered between the die 45 and the mat 47. The die 45 is vertically movable on the support frame by means of rams 48 between a raised disengaged position spaced-apart from the mat 47 and a lowered extended mat engaging position for clamping the webs between the die 45 and the mat 47. The die 45 incorporates heating elements to heat the die to a preset desirable sealing temperature for sealing the webs together to provide open ended pockets forming pouches in the overlapped webs. When the die 45 is raised into the retracted position the webs are again fed on one step and the next pouch configuration is formed in the webs.
The silicone mat is typically about 6 mm thick and has a hardness in the range 55 shore A. The mat has a smooth surface and is preferably compression moulded to ensure uniform density.
Downstream ofthe sealing station 22 the sealed webs are delivered past vertical edge trimming blades 50 which engage and part excess material 52 from the side edges of the joined webs. Such excess material 52 is delivered into extraction conduits 54'mounted adjacent each trimming blade 50 for reception and removal of off-cut material. Each conduit 54 terminates in a waste bin having associated means for applying a vacuum to the bin and the extraction conduit 54 for drawing the off-cut material into the bin.
It will be noted that the blades 50 are not fixed, but can move vertically so that the whole of the blades are used and evenly worn down when cutting the web material.
The webs with the formed pouches are then delivered through a guillotine which cuts the joined webs transversely to separate each pouch from a leading end of the joined webs. The pouches are delivered by a take-off conveyor 62 for packaging.
Alternatively, the pouches can be wound up on a roll and later separated.
The invention is not limited to the embodiments hereinbefore described but may be varied in both construction and detail within the scope of the appended claims.
