Abstract
A loading system (10) for loading packaging cards (14) with blister cards (22), which system comprises a magazine (15) for holding a supply of blister cards and operable controllably to release sequential blister cards onto a stationary runner (32) disposed around a portion of a feeder wheel (24), at an input position of the feeder wheel, the feeder wheel having means (30) to convey the blister cards in sliding contact with said runner to a transfer position of the feeder wheel, and means (26) sequentially to transfer conveyed blister cards for loading onto packaging cards during synchronized movement between the transfer means and the packaging cards.
Description
- The present invention relates particularly though not exclusively to a system for loading blister cards onto packaging cards, and more particularly though not exclusively to a loading system that minimises damage to the surface of the blister card during a loading process, and still more particularly though not exclusively to a loading system that comprises a gate mechanism and feeder wheel to carry out the loading process whilst minimising dame to the surface of the blister card.
- Current commercial blister card loading systems transfer successive blister cards from a magazine, or other known storage system, into contact with a corresponding packaging card. The packaging cards often comprise an adhesive element with which the packaging cards and the blister card are secured to one another. These adhesive elements may be applied to the packaging card in an activated form, or alternatively, heated such that preapplied adhesive becomes activated. Thus the time between the adhesive being heated, or applied to the packaging card, and the location of the blister cards upon the packaging card must be kept to a minimum so as to limit the exposure of the active adhesive to the air, during which time it will lose part of its adhesive qualities. The means of transferring the blister cards from the magazine to a position of contact with the packaging card are therefore high speed mechanisms that often subject the blister card to potentially damaging levels of friction.
- Examples of known loading systems are those that feed blister cards onto a rotating feeder wheel that transfers successive blister cards to a position proximate the packaging, ready for a final accurate transfer mechanism to perform the final loading action. However, such systems often result in damage being caused to the blister cards as they are brought into contact with the revolving surface of the feeder wheel. Such damage not only lowers the aesthetic appeal of the blister card, but also risks rupturing the blisters and loss of, or damage to, the any contents thereof.
- There is, therefore, a need for a loading system that may transfer blister cards from a magazine to a position proximate the packaging cards, into which they are to be loaded, which avoids bringing the delicate blisters of the blister cards into contact with a rotating surface, and yet will quickly transfer the blister cards, so as to minimise the risk of the adhesive portions of the packaging cards losing their adhesive qualities.
- The present invention described herein seeks to overcome or at least mitigate these problems highlighted in the loading systems of the prior art.
- A first aspect of the present invention provides a loading system for loading packaging cards with blister cards, which system comprises a magazine for holding a supply of blister cards and operable controllably to sequentially release blister cards onto a stationary runner disposed around a portion of a feeder wheel, at an input position of the feeder wheel, the feeder wheel having means to convey the blister cards in sliding contact with said runner to a transfer position of the feeder wheel, and means sequentially to transfer conveyed blister cards for loading onto packaging cards during synchronized movement between the transfer means and the packaging cards.
- Preferably, a guide rail is provided to cooperate with said stationary runner and thereby to retain the blister card within a working reach of a feeder wheel as they are conveyed by the feeder wheel.
- Preferably, the means by which the feeder conveys the blister cards comprises lugs that protrude from the surface of the feeder wheel, and which are brought into abutment with a trailing edge of the blister cards by rotation of the feeder wheel, and through which abutment subsequent conveyance of the blister card is achieved.
- Preferably, the magazine comprises protrusions that abut a proximate surface of a blister card of the magazine, thereby preventing any blister cards from being released, which protrusions may be controllably moved out of abutment with said proximate surface, by displacement of the protrusion and said surface relative to one another, and thereby releasing a blister card from the magazine.
- Preferably, the magazine comprises pivotable hooks, the terminal ends of which form said protrusions.
- Alternatively, the magazine may comprise Archimedean screws that release the successive blister cards from the magazine through rotation of the Archimedean screws.
- Another alternative being that the magazine comprises star wheels which may be rotated to release successive blister cards from the magazine.
- Preferably, the loading system is arranged such that two or more blister cards may be released onto runners of the feeder wheel, and thereafter loaded onto the same packaging card, simultaneously.
- A second aspect of the present invention provides a method of loading a packaging card a blister card, which method comprises the steps of controllably releasing blister cards sequentially, from a magazine for holding a supply of blister cards, onto a stationary runner disposed around a portion of a feeder wheel, at an input position of the feeder wheel, conveying the released blister cards, in sliding contact with said runner, to a transfer position of the feeder wheel, using a conveying means of the feeder wheel, and sequentially transferring conveyed blister cards for loading onto packaging cards during synchronized movement between the transfer means and the packaging cards.
- Preferably, the blister cards are controllably released from the magazine by moving protrusions out of abutment with proximate surfaces of the blister cards.
- Preferably, the protrusions comprise the end of pivotable hooks and the protrusions are moved out of abutment with said proximate surfaces by pivoting those hooks.
- Alternatively, the protrusions comprise the thread of Archimedean screws and the protrusions are moved out of abutment with said proximate surfaces by rotating the Archimedean screws.
- A further option being that the protrusions comprise the lugs of rotatable star wheels and that the protrusions are moved out of abutment with said proximate surfaces by rotating the star wheels.
- Preferably, two or more blister cards are released onto the runners of the feeder wheel simultaneously, and are thereafter loading onto the same packaging card simultaneously.
- A preferred embodiment of the invention will now be described, by way of example only, with reference to the accompanying drawings in which:
-
FIG. 1 shows a perspective view of a loading system according to preferred embodiment of the invention; and -
FIG. 1A shows a schematic side view of the loading system ofFIG. 1 . - The present invention provides a
loading system 10 which comprises agate mechanism 40 for intermittently releasingblister cards 22 from amagazine 15. As theblister cards 22 are released, they are transferred to locate upon respective packaging cards 14 that are disposed upon apackaging conveyor 28. The packaging cards 14 comprise a series ofapertures 11 that accommodate blisters 21 that are disposed upon one side of theblister card 22. - Referring to
FIG. 1 , the preferred embodiment of theloading system 10 comprises amagazine 15, containingblister cards 22, positioned vertically above afeeder wheel 24 that is in turn positioned above arotary suction arm 26. This assembly is positioned overpackaging conveyor 28 and may advantageously be positioned proximate an exit end of aheating hood 12. In the illustrated embodiment, themagazine 15 comprises two adjacent stacks ofblister cards 22 so as to allow simultaneous loading of twoblister cards 22 upon each packaging card 14. It is, however, contemplated that the number of stacks ofblister cards 22 may be higher or lower than the two shown in this exemplary embodiment. - The
magazine 15 is fitted with agate mechanism 40 which can be controlled to intermittently release thelowermost blister cards 22 of each stack in themagazine 15, ontorunners 32 of afeeder wheel 24. Thegate mechanism 40 comprises, in a preferred embodiment, a pair of hooks 44 (best shown inFIG. 1A ), hinged upon either side of themagazine 15. The terminal ends of each hook 44 are disposed inwardly of themagazine 15 so as to come into abutment with a lowermost surface of thelowermost blister cards 22 of each stack in themagazine 15, which abutment retains all theblister cards 22 in themagazine 15. - The hooks 44 may be brought out of abutment with the
lowermost blister cards 22 by pivoting the hooks 44 about pivots 42 a sufficient amount to allow thelowermost blister card 22 to pass between the terminal ends of the those hooks 44. After the release of thelowermost blister card 22 of each stack, the hooks 44 pivot back to their original orientation to prevent the release ofsuccessive blister cards 22 from themagazine 15. Alternatively, it may be that dual pairs ofgate mechanisms 40 are employed such that a first gate mechanism retains thepenultimate blister cards 22 of each stack, whilst thesecond gate mechanism 40 retains only thelowermost blister card 22 of each stack. - It is also conceived that the same gate mechanism function may be achieved using Archimedean screws or star wheels (not shown) as alternatives to the hooks 44 described above. For example, the Archimedean screws could convey the
blister cards 22 down through themagazine 15 in a controllable fashion and would release the lowermost blister cards as they reach the terminal free end of the screw. Likewise, star wheels may be positioned such that lugs, disposed around the periphery of each star wheel, come into contact with the free edges of theblister card 22. The star wheels may then be controlled so as to free thelowermost blister cards 22 of themagazine 15 at controllable intervals. - Once the
lowermost blister card 22, of each stack, has been freed from restraint by thegate mechanism 40, it will descend, under gravitational attraction, to a position of rest uponrunners 32 of thefeeder wheel 24. Therunners 32 are provided in pairs for each blister card, so as to support theblister card 22 in a stable condition, and the number of pairs ofrunners 32 corresponds to the number of stacks contained in the magazine, so that theblister cards 22 may be accommodated side by side on therunners 32. - The
runners 32 follow a path proximate to but offset from the perimeter offeeder wheel 24, as is more clearly illustrated inFIG. 1A . Thefeeder wheel 24 further comprisesguide rails 33, that similarly follow a path proximate the perimeter of thefeeder wheel 24, although offset therefrom by a greater distance than that of therunners 32. The releasedblister cards 22 drop onto therunners 32 directly beneath themagazine 15 and remain in place until alug 30 is brought into contact with their trailing edges. Theblister cards 22 are disposed upon therunner 32 with the blisters 21 protruding toward thefeeder wheel 24, therunners 32 being shaped and arranged so as to contact a flat underside of theblister card 22 rather than the blisters 21 themselves. Thus, at the point at which theblister cards 22 are brought into contact with thefeeder wheel 24, the blister cards are only subject to the forces of their own weight resting upon therunners 32. - The
lugs 30 protrude radially from the surface of thefeeder wheel 24 and thereby follow an annular path as thefeeder wheel 24 is rotated. In the preferred embodiment, thelugs 30 are provided in pairs, eachlug 30 of each pair being aligned with theother lug 30 of that pair. There are provided four such pairs oflugs 30 around the periphery of thefeeder wheel 24. If a different number of stacks ofblister cards 22 were being used, the number oflugs 30 in each set would be adapted accordingly from the exemplary pairs. Once in abutment with an aforementioned trailing edge of ablister card 22, thelugs 30 convey theblister cards 22 around a portion of the periphery of thefeeder wheel 24. A terminal end of the guide rails 33 is positioned proximate the location at which theblister cards 22 are initially positioned upon therunners 32, such that, once theblister cards 22 are conveyed by thelugs 30, theblister cards 22 quickly become disposed intermediate aguide rail 33 and therunners 32. Theguide rail 33 prevents theblister cards 22 from separating from therunners 32. Thus theblister cards 22 are conveyed by thelugs 30 around a portion of thefeeder wheel 24 in direction Tc until they reach a lowermost point of thefeeder wheel 24, at which point eachblister card 22 is released from thefeeder wheel 24 as a result of the termination of the guide rails 33. As eachblister card 22 is released, it comes into contact with acorresponding suction head 34 of arotary suction arm 26, with which a seal is created. Theblister cards 22 are thereby secured to the rotarysuction arm unit 26, and are orientated such that the blisters 21 are protruding away from therotary suction arm 26. - In the preferred embodiment, the rotary
suction arm unit 26 comprises two pairs of diametricallyopposed arms 35 each comprising asuction head 34. It is contemplated that the number of pairs may be varied according to the requirements of the system, wherein three pairs of arms may, for example allow for quicker withdrawal ofblister cards 22 from thefeeder wheel 24. Similarly, the number of arms in each set may be varied from the illustrated pair to correspond to the number of stacks ofblister cards 22 in themagazine 15. - Once a seal has been created between the rotary
suction arm unit 26 and eachblister card 22, theblister cards 22 are displaced out of abutment withlugs 30 by pivoting the rotarysuction arm unit 26 about its central axis in direction Ta. Thelugs 30 are thereby freed to follow the return path of thefeeder wheel 24. The rotation of the rotarysuction arm unit 26 is synchronised with that of thefeeder wheel 24, such that asuction head 34 is correctly positioned proximate the lowermost point on thefeeder wheel 24, as eachsuccessive blister card 22 is released from thefeeder wheel 24. - The rotary
suction arm unit 26 conveys theblister cards 22 about an annular path that brings them into a correct position upon a packaging card 14 that is disposed upon thepackaging conveyor 28. At this point, the blisters 21 of theblister cards 22 are disposed toward the packaging card 14 and are each aligned in registry with a correspondingaperture 11 in the packaging card 14. - Once
blister cards 22 are positioned correctly with respect to a packaging card 14, the seal between thoseblister cards 22 and the respective suction heads 34 is broken, by virtue of, for example, the removal of a negative pressure between thesuction head 34 and a surface of theblister card 22. As the seal is broken, theblister cards 22 are freed from the rotarysuction arm unit 26 and are conveyed upon the packaging cards 14, by packagingconveyor 28. - The
packaging conveyor 28 conveys the packaging cards 14, loaded withblister cards 22, betweencompression rollers 18 and 20. Thecompression rollers 18 and 20 are spaced apart and eachcompression roller 18, 20 comprises at least one shaped pad, such aspad 36 illustrated inFIG. 1 . In the preferred embodiment, thepads 36 are each sized and shaped to accommodate twoblister cards 22 disposed adjacent one another and to protect the blisters 21 from damage whilst compressing the packaging card 14 against a flat underside surface of theblister card 22. The compression ensures a good contact between adhesive portions of the packaging card 14 and the flat underside surface of theblister cards 22, thereby providing a good seal between the two. Additionally,compression rollers 18, 20 are synchronised with thepackaging conveyor 28 such that thepads 36, upon eachcompression roller 18,20, simultaneously come into contact with both an uppermost surface of theblister cards 22 and a lowermost surface of the packaging card 14, and avoid coming into contact with adhesive portions of packaging card 14 that are not covered by theblister cards 22. - The loaded packaging card 14 is, thereafter, passed to further mechanisms whereby the packaging process is completed. For example, a further roller system may be employed to fold a separate panel of the packaging card 14 over the uppermost surfaces of the
blister cards 22. - It is contemplated within the scope of the invention that the exact nature of the non essential features of the loading system may be altered whilst not departing from the scope of the present invention. For example, the rotary suction arms 20, may be replaced with mechanical gripping assemblies which perform the function of transferring the
blister cards 22, down into position of alignment with the packaging 14. Additionally, the exact orientation of themagazine 15, is not a limiting feature of this invention and it is entirely contemplated that the magazine may be at any angle; not only vertical or horizontal, as shown inFIGS. 1 and 1A . Further, the exact arrangement ofrunners 32 andguide rails 33, illustrated inFIG. 1 , is not a limiting feature of the invention and it is contemplated that the paths along which theblister cards 22 are conveyed may be adapted to suit the exact requirements of the loading system as necessary. As described above, numerous alternatives to the use of pivotable hooks 44 may be employed to achieve thecontrollable gate mechanism 40. - Any directional references used in the above description, such as “uppermost”, “lowermost”, “upper”, “lower” are not limiting features and are incorporated purely for the benefit of clarity and ease of reference.
