Definitions
- THIS INVENTION relates to the prevention of bounce occurring when small objects are loaded into pockets into which they may be subsequently sealed.
- the invention is particularly well-suited, although not exclusively so, to preventing solid medication doses, such as tablets, from bouncing when falling into a pocket formed by the cavity of a blister of a blister sheet.
- the provision of prescribed medication to a patient by means of a pre-loaded blister package is commonly used to enable the patient to carry several days supply of prescribed doses of medication.
- the doses are prescribed by a doctor and appropriately packaged by a pharmacist to provide the patient with a sealed blister sheet having individual blisters marked with the days and times at which the doses in each blister are to be administered to the patient.
- the program determines which blister of the blister sheet is to be loaded at a particular moment with a particular prescribed medication.
- the blister sheet is normally loaded while inverted and has its blisters extending downwardly into respective openings provided in a horizontal support table.
- the table can be indexed horizontally in its own plane by a mechanism to bring each blister in turn to a pre-arranged loading position at which the appropriate medication dose selected from one of the containers can be released into its cavity.
- the blister sheet is normally made from a plastics material which has a natural resilience, and it is convenient to rely on gravity to transfer a dose from a selected storage container to the blister cavity.
- the natural resilience of the blister sheet can cause a dose to bounce back out of the blister cavity if it is the first dose to be placed in it, and there is also a risk that the descending dose will impact on a dose already in the cavity and damage one or both doses as a consequence.
- the distance through which the dose drops from the underside of the container should be made as small as is practical. However there is a limit to the reduction of this distance if there is to be no risk of a dose bouncing out of the cavity interfering with the operation of the indexing mechanism.

- US 3,775,941 discloses an article packaging machine particularly suitable for use in depositing capsules into rows of pockets formed in a web. As the web pockets are formed by separate apparatus, the web is periodically advanced a predetermined distance.
- the packaging machine includes a depositer which oscillates over the web pockets, the depositer moving forward with the advancing web. Shortly after the web movement stops, the depositer reaches the end of its forward stroke where the first capsules are discharged. Remaining capsules are sequentially discharged during the return stroke, the capsules being arranged in columns in vertically arranged passageways formed in the depositer. A plurality of vertically arranged pin gates in each passageway hold the capsules therein until the depositer reaches the proper discharge zone.
- a top pin gate opens and a bottom gate closes in each of the passageways. This allows a column of capsules to drop within each of the passageways, and be held therein by the bottom gate.
- the depositer is thus ready to repeat the cycle when the web is once again advanced.
- a stationary transition member is mounted between the depositer and web, this member having a plurality of openings extending therethrough which openings are located over the web pockets to be filled; because the openings are suitably shaped, this member accepts the discharged capsules so as to allow them to clear the moving depositer, and at the same time guides the discharged capsules into the web pockets.

Description
- THIS INVENTION relates to the prevention of bounce occurring when small objects are loaded into pockets into which they may be subsequently sealed. The invention is particularly well-suited, although not exclusively so, to preventing solid medication doses, such as tablets, from bouncing when falling into a pocket formed by the cavity of a blister of a blister sheet.
- For convenience and ease of understanding, the description of the invention which follows has been limited to its use in loading medication doses into blister cavities of a blister sheet but it is to be understood that the invention is applicable to a much wider range of usage than this particular activity.
- The provision of prescribed medication to a patient by means of a pre-loaded blister package is commonly used to enable the patient to carry several days supply of prescribed doses of medication. The doses are prescribed by a doctor and appropriately packaged by a pharmacist to provide the patient with a sealed blister sheet having individual blisters marked with the days and times at which the doses in each blister are to be administered to the patient.
- It is convenient to mechanize the loading of the blister sheet with the prescribed doses to save time and apparatus to achieve this has been devised which relies on a large number of storage containers having bottom openings from which tablets are released into the cavities of blisters in accordance with a computerized program. The program determines which blister of the blister sheet is to be loaded at a particular moment with a particular prescribed medication. The blister sheet is normally loaded while inverted and has its blisters extending downwardly into respective openings provided in a horizontal support table. The table can be indexed horizontally in its own plane by a mechanism to bring each blister in turn to a pre-arranged loading position at which the appropriate medication dose selected from one of the containers can be released into its cavity.
- The blister sheet is normally made from a plastics material which has a natural resilience, and it is convenient to rely on gravity to transfer a dose from a selected storage container to the blister cavity. However the natural resilience of the blister sheet can cause a dose to bounce back out of the blister cavity if it is the first dose to be placed in it, and there is also a risk that the descending dose will impact on a dose already in the cavity and damage one or both doses as a consequence.
- To reduce the risk of damage occurring when a dose is dropped into a blister, the distance through which the dose drops from the underside of the container should be made as small as is practical. However there is a limit to the reduction of this distance if there is to be no risk of a dose bouncing out of the cavity interfering with the operation of the indexing mechanism.

US2006/0076077 discloses a method and an apparatus that serve to place tablets into pockets of thermoformed bottom foil. The tablets are accumulated as they are located in their flat position. The tablets are rotated in an erecting station such that they reach an approximately upright position. A plurality of lines of approximately upright tablets is formed. The approximately upright tablets are rotated back into their flat position by a transfer unit including a plurality of channels. The tablets are then placed into the pockets of the bottom foil by the transfer unit. - None of the above references recognizes nor solves the problems that occur when objects are allowed to free-fall into a cavity under action of gravity. In particular there is a risk a fast moving object bouncing out of a cavity and when two or more objects are being loaded into the same cavity, the impact of a falling object can damage or dislodge an object previously loaded into the same cavity.
- An object of this invention is to reduces the risk of problems occurring during loading of doses or other hard objects into a blister cavity.
- In accordance with the present invention, there is provided an apparatus for loading individual cavities of a blister sheet with doses that are formed by small hard objects released into the cavities from above, including: dose-storage containers and first means for locating the individual dose-storage containers holding the objects at a level above the position of a blister cavity to be loaded; second means for releasing an object from the respective dose-storage container so that it falls down a path leading downwards towards the cavity; and third means located in the path of descent of the object and configured to retard its rate of descent to an acceptable level before it. reaches the cavity, wherein an acceptable level is a level at which the object will not bounce back out of the cavity, the third means including deflectors provided by the internal surfaces of respective axially parallel cylindrical bores formed through a horizontal plate located between the level of the blister sheet and the level of the dose-discharge position of the containers, wherein the fall height and the deflectors are configured with respect to the objects such that a falling object is deflected by the respective deflector laterally towards a side-wall of the selected blister such that it impacts the side wall.
- The portion of the lower end-portion of the bore opposite the side first struck by a descending tablet may be rebated to avoid the risk of tablets stacking up against one side of the cavity and possibly interfering with the correct operation of the apparatus.
- When a particular dose is to be loaded into a selected blister cavity, an indexing mechanism of the table may be operated to bring the cavity of the blister to be loaded and its associated deflector, to a position at which the deflector is located beneath the lower end of a storage container from which the dose is to be released. The dose then strikes the deflector during its descent, and its momentum is reduced as a consequence. The deflection also deflects the descending dose towards a side-wall of the selected blister. Impact with the side wall slows down the descent still further so that the risk of the descending dose damaging itself or other doses which may already be in the blister is reduced still further.
- The invention will now be described in more detail, by way of examples, with reference to accompanying partly-diagrammatic drawings, in which:
-
-
FIGURE 1 is a perspective view from above of a relatively thick plate penetrated by an array of axially-parallel bores inclined to the plane of the plate and providing one form of deflecting means; -
FIGURE 2 is a diagrammatic plan view of the plate offigure 1 ; -
FIGURE 3 is a side view of the plate offigure 2 ; -
FIGURE 4 is an end view of the plate offigure 2 ; -
FIGURE 5 shows diagrammatically, and to a greatly enlarged scale, the path of descent of a dose through one bore of the plate, the dose being released from a dose-storage container above the plate and striking against a deflecting surface provided by the interior wall of the bore so that the dose is deflected towards the upper internal wall of a blister cavity beneath; and, -
FIGURE 6 shows a modification offigure 5 and where identical parts bear identical reference numerals but they are primed, and the lower end of the bore is rebated. - For convenience the example of the invention now to be described is designed to be used in conjunction with apparatus of the general design described in
United States Patent Specification Nos. 7,225,597 B1 ;7,426,814 B2 ; and,7,510,099 B2 . These specifications are hereby inserted by way of reference to enable the reader to understand how the apparatus works and to avoid burdening the present specification with unnecessary detail well known in the art. In the first two of the above-numbered prior art patent specifications a blister support table is identified inFigure 1 by the reference number 'thirty' and the same reference numeral is used infigure 5 of the present specification to denote a like part. The support table 30 offigure 5 is provided withopenings 14 for the reception ofrespective blisters 15 of aninverted blister sheet 12 moulded from a resilient plastics material and placed blistered-side down on the table 30. -
Figures 1 to 4 show a flat thick nylon plate 1 formed with an array of identical cylindrical and axially-parallel bores 2 inclined at an angle to the plane of the plate of about sixty degrees. The plate 1 is slightly less than two centimetres thick. The diameter of each hole is slightly more than sixteen millimetres. None of these dimensions or angles is critical and are only given as one example of the invention. -
Figure 5 shows one of a number of dose-storage containers 6 located at a level spaced above theplate 3 and at a dose-discharge position vertically above the upper end of abore 2. A mechanism (not shown) at the lower end of thecontainer 6 and controlled by a computerized control system (also not shown) allows a dose to be released from thecontainer 6 in response to a control signal generated by the system and controlling operation of the apparatus. - A dose in the form of a hard solid medication tablet or pill, shown at 4 in
figure 5 , is dropped from the lower end of thecontainer 6 into the upper end of thebore 2 immediately beneath, and descends along the fall line indicated by a broken line infigure 5 . As the axis of thebore 2 is at thirty degrees to the vertical, the dose strikes against the inside wall of the bore intermediate its ends, at a location 7. The distance through which the dose falls before striking the location 7 is found empirically and ensures that the momentum of the dose 4 is insufficient to cause damage to I when impacting on the location 7. This fall distance may be varied in the apparatus to achieve this result and it will be found empirically and changed to suit different types of dose. The contact of the dose with the location 7 acts to reduce the vertical momentum of the dose 4 and deflects it down theinclined bore 2 towards its lower end. The dose leaving the lower end still has a horizontal component of velocity so that it impacts on the side wall of the blister cavity positioned beneath the lower end of thebore 2 and associated with it.. - Were the dose 4 allowed to fall vertically onto the floor of the cavity, there would be a risk that the resilience of the material from which the blister sheet is made, might bounce the dose 4 back out of the cavity. It might then cause damage to an indexing mechanism used to move the table 30. There is also risk that a dose descending vertically into the blister cavity from the
bore 2 could have sufficient momentum to impact against, and possibly damage itself and/doses already in the blister cavity. - In the modification of
figure 5 shown infigure 6 , arebate 100 is provided on the side of the lower portion of thebore 2 opposite the location 7. Thisrebate 100 serves to accommodate overflow of doses within the cavity of a blister being loaded, and also to prevent doses from stacking up at one side of the blister and possibly blocking the lower end of thebore 2. - Although the invention has been specifically described in the above examples with reference to medication doses being loaded into blister cavities, it is to be understood that its usage is not limited to this application. The invention is capable of being used in any apparatus where it is required to reduce the velocity of descent of hard solid objects which might otherwise free-fall with an undesirably high velocity. The deflecting bores of such apparatus may, for example, be used to reduce the velocity with which tablets or other solid medication doses are inserted into respective single dose blisters, or to orientate the dose to a desired position required for entry into a blister.
