Definitions

  • the present invention relates to an apparatus for extracting articles, especially pharmaceutical tablets, from blister packs.
  • Blister packs are a very common means of packaging pharmaceutical tablets. Such packs generally comprise a sheet of initially flat clear plastics material in which are formed a series of wells. A tablet is inserted into each of the wells, the open ends of which are sealed by means of a sheet of aluminium foil which is attached to the plastics material sheet. Each tablet is thus sealed in its own well until use, when the clear plastics blister is depressed by finger pressure and the tablet is forced out through the foil backing.
  • an apparatus suitable for extracting articles from a blister pack which apparatus comprises a first member having a recess defined by a first recess defining portion and a second recess defining portion, the first recess defining portion being translationally movable with respect to the second recess defining portion, and a second member, the first and second members being adapted to hold a blister pack and the second member being adapted to bear on one or more blisters of a blister pack when so held so as to displace an article, when enclosed by one of said blisters, out of the blister pack towards the recess.
  • the first and/or second member(s) may be plates, but it is preferred that the first and second members both be parallel rollers.
  • the recess defining portions which may be serrated, are desirably formed from one or more dogs or collars of the first roller and it is preferred that the position of at least one of the recess defining portions be movable, with respect to the second roller, in a direction parallel with axes of rotation of the rollers.
  • Means may therefore be provided for moving the or a recess defining portion.
  • the moving means may comprise an electromagnetically operable device but preferably comprises a manually operable lever, the lever conveniently being provided with locking means for locking it in one of a plurality of positions and advantageously being operable against and/or with the action of spring biasing means.
  • means for collecting de-blistered blister packs and/or articles extracted from blister packs is provided.
  • the collecting means may comprise an outlet in a casing for the apparatus and/or one or more receptacles.
  • Sorting means such as an appropriate sieve, may also be provided for sorting articles extracted from blister packs from de-blistered blister packs.
  • the apparatus may comprise guide-means for guiding a blister pack to a position where the blister,pack can be gripped by the first and second rollers.
  • the guide-means may enable a blister pack to be guided to different positions along a line parallel with the axis of rotation of the first roller.
  • the first and second members be spring biased towards one another.
  • an apparatus 1 in accordance with the present invention which comprises a base 3, and an essentially cubic housing 5 having a front wall 7, a back wall (not shown), a left-hand side wall 9, a right-hand side wall 11 and an upper surface 13.
  • the upper surface 13 comprises an opaque, metal rear portion, 13a, covering approximately the rear three quarters of the upper surface, and a transparent plastics material front portion 13b, covering the front quarter of the upper surface.
  • a transverse slit 15 through which a blister pack to be deblistered can be inserted.
  • Located approximately centrally on the upper surface 13 is a guide means 17 for guiding the feeding of a blister pack through the slit.
  • the guide means 17 is generally similar to a lathe turret feed and comprises a cuboid structure 19 rotatable about a centrally located vertical axis in such a way that any of the four lateral sides of the cuboid may lie along the slit between the front portion 13b and the rear portion 13a of the upper surface.
  • a locking screw 21 On top of the cuboid structure 19 is located a locking screw 21 on the axis of rotation of the guide means 17. The locking screw 21 can be loosened manually for the guide means 17 to be rotated, and then tightened, also by hand, when the guide means 17 is in the desired orientation. It will become apparent later why it is desirable to have different lateral faces of the guide means 17 adjacent the slit 15.
  • first roller 23 has a horizontal axis of rotation and is journalled into the left and right hand side walls 9 and 11 of the housing 5.
  • the first roller 23 may be caused to rotate by rotating a belt gear 25 located outside the left hand side wall on a shaft 27 which is formed as an extension of the first roller 23.
  • first gear wheel 29 which meshes with a second gear wheel 31 mounted on a second roller 33 lying adjacent the first roller 23 and joumalled in a left hand mounting block 35 and a right hand mounting block 37 affixed to the inside of the left and right hand side walls 9 and 11 respectively by means of respective bolts 39 and 41.
  • the second roller 33 constitutes a second member.
  • the journalling of the second roller 33 may be such as to spring-bias the second roller 33 against the first roller 31 but, whether this feature is present or not, the second roller 33 will, in use of the apparatus 1, route in an opposite sense to that of the first roller 23.
  • the second roller 33 has a smooth surface 43 and is of uniform diameter.
  • the left hand half of the first roller 23, that is the portion adjacent the first gear wheel 29, is the same diameter as the second roller 33, and, apart from a radial serrated band 45 at the right hand end of this half of the first roller 23, has a smooth surface 47.
  • the right hand half of the first roller 23 has only about two thirds the diameter of the left hand half.
  • a fixed dog 49 is mounted on the right hand half of the first roller 23 a short distance from the centre of the roller.
  • the radius of the fixed dog 49 is the same as the radius of the left hand half of the roller, and the edge is serrated.
  • To the right of the fixed dog 49 a slidable collar 51 is mounted.
  • the slidable collar 51 comprises two serrated radial dogs 53 and 55 having the same diameter as the left hand half of the first roller 23 and a neck 57 joining these two dogs.
  • the neck 57 has a wider bore, of course, than the diameter of the right hand half of the first roller 23 (so as to be able to fit over it), but a narrower diameter than the left hand half.
  • the right hand end of the slidable collar 51 is a smooth-surfaced anchoring portion 59, which has a diameter the same as the diameter of the left hand end of the first roller 47.
  • the left hand end of the slidable collar 51 is serrated.
  • the anchoring portion 59 has a radial circular hole 61 spanning its entire diameter for accomodating a plug 63 ( Figure 3).
  • the plug 63 is located in a diametrical slot 65 in the first roller 23, by virtue of which the plug 63, and hence the entire slidable collar 51, can move axially with respect to the remainder of the first
  • a blister pack is fed between the first and second rollers 23 and 33 with the blisters directed towards the second roller 33, which has a smooth surface along its entirity, the blister pack being so positioned that articles contained within the blisters can be pushed out of the blisters through the back of the blister pack into the recess defined by two dogs of the first roller 23 or by a wide diameter portion of the first roller 23 and a dog which thereby constitute recess-defining portions of the first roller. It will be understood that by varying the axial position along the rollers at which the blister pack is fed into the apparatus, differently sized blister packs may be accomodated and de-blistered.
  • blister packs of differing sizes may be deblistered by the apparatus.
  • Articles forced out of a blister pack being deblistered are collected in a drawer 67 ( Figure 1) which slides on the base 3 into the front of the apparatus 1 through an appropriately shaped hole in the front surface 7 of the housing 5.
  • the position of the slidable collar 51 is determined by a selector mechanism 69, details of which are apparent from Figures 3 and 4.
  • the slideable collar 51 is, as has already been described, mounted on the right hand half of the first roller 23, that is, the half with the narrower diameter.
  • a bore 71 is formed along the axis of the first roller 23 from the right hand end and terminates in the slot 65 within which the plug 63 may move axially along the first roller 23.
  • a rod 73 is inserted into the bore 71 and terminates within the plug 63, which is also provided with a bore 75, where it is retained by a pin 77.
  • the other end of the rod 73 is jouralled in a bearing 79, where it is fastened by a nut 81 and bolt 83 to a selector arm 85 extending upwardly at right angles to the axis of the first roller 23.
  • the free end of the selector arm 85 is provided with a handle 87 for ease of manual manipulation and extends through a casing 89 for the selector mechanism 69. Lateral movement of the selector arm 85 causes the rod 73 to move axially with respect of the first roller 23 and will cause the position of the slidable collar 51 to be altered with respect to the first roller 23.
  • a gate may be provided in the casing 89 of the selector mechanism 69 so that the selector arm 85 can be locked in one of a plurality of axial positions by appropriate rotary movement of the selector arm 85 about the axis of the first roller 23.
  • the selector mechanism 69 may incorporate a spring so that the slidable collar 51 is spring-biased to the left hand end of the first roller 23.
  • blister packs may be deblistered with relative ease.
  • the position of the recesses and recess-defining dogs of the first roller 23 may be altered by means of the selector mechanism 69, and, in addition, the blister packs themselves may be fed to the apparatus at different axial positions by means of the guide means 17 comprising the lathe type turret feed.
  • the arrangement in Figure 1 shows two faces of the turret feed, there being a channel for accommodating the blisters of a blister pack at a different relative position on each face. This enables blister packs to be fed between the first and second rollers 23 and 33 at different axial positions along the first roller. A clear plastics material sheet covers each channel, the better to guide the blister packs between the first and second rollers 23 and 33.
