The present invention relates to dispensers, and more specifically to a mechanism for dispensing objects from an array-type package inside individual containers thereof, and to a cutting mechanism for cutting individual containers of the array-type package.
There are many types of food objects, goods or pellets packages provided with a plurality of independent or individual small containers connected to one another at a common top surface thereof. Each individual container contains a predetermined quantity and/or selection of objects, pellets or goods such as, but not limited to, medications, pills, vitamins, candies, coffee beans, tea, seeds or the like. More specifically, when used with medication pills, each set of a predetermined individual container needs to be taken a specific day, and at a predetermined time by the patient. These type of packages are usually prepared in advance by a pharmacist or other health professional and it is the responsibility of the patient to take each set of pills, or a caregiver thereof (as a relative, spouse, visiting health professional, etc.), to administer each set of pills at the right time, the right day, and not to make any mistake on the specific individual container it is time to open.
Accordingly, there is a need for getting the content of any individual container at any time, irrespective of the location of the container within the array. Even manually, such an operation often gets difficult, considering the fact that such array-type packages are usually made out of a common top surface typically made out of coated paper or the like material covering the containers typically made out of plastic (PVC—polyvinyl chloride) material or the like. First, the patient needs to properly locate the individual container among the multiple containers, and typically tear it off from the package. Second, to access the pills of the specific individual container, the patient typically needs to either peel off or perforate the top cover of the container using a sharp tool or the like. Known dispensers are not capable of dispensing the content of any selected individual container within an array, especially not dispensing the content into its original container.
Accordingly, there is a need for an improved cutting mechanism for selectively dispensing pea-size objects, pills or the like from individual containers of an array-type package.
According to an aspect, a mechanism for dispensing pills in an individual container is provided, the individual container being one of a plurality of individual containers in an array-type pill package in which the individual containers are attached to one another in an arrangement of rows and columns and have a common top surface, the plurality of individual containers extending from the common top surface on a same side thereof. The mechanism includes: a chassis; a package holder supported by the chassis for supporting the array-type pill package; a cutting mechanism supported by the chassis and configured to cut a sidewall of the individual container adjacent the common top surface in order to separate the individual container from the array-type pill package; a dispensing mechanism supported by the chassis and configured to receive and dispense a cut individual container therein; and a control system operatively connected to at least one of the package holder and the cutting mechanism, the control system being configured to control a relative position of the cutting mechanism and the package holder along at least two degrees of freedom.
In an embodiment, the package holder and the cutting mechanism are movably mounted to the chassis and the control system is configured to control the relative position of the package holder and the cutting mechanism along a first of the at least two degrees of freedom by displacing the package, and along a second of the at least two degrees of freedom by displacing the cutting mechanism.
In an embodiment, the control system includes a first motor configured to displace the package holder along the first degree of freedom, and a second motor configured to displace the cutting mechanism along the second degree of freedom.
In an embodiment, the package holder has a cylindrical shape with a periphery and a longitudinal axis, the first motor being configured to rotate the package holder about the longitudinal axis, and the second motor being configured to actuate the cutting mechanism in a plane generally tangent to the periphery of the package holder.
In an embodiment, the second motor is configured to actuate the cutting mechanism along a displacement axis in the plane generally tangent to the periphery of the package holder, the displacement axis being generally parallel to the longitudinal axis of the package holder.
In an embodiment, the dispensing mechanism includes a guiding slide and a dispensing tray, the guiding slide being configured to receive the cut individual container and displace it towards the dispensing tray.
In an embodiment, the guiding slide and dispensing tray are operatively connected to the cutting mechanism and displaceable therewith along the displacement axis.
In an embodiment, the periphery of the package holder includes an axial zone without any individual containers, said axial zone being sized to allow the cutting mechanism to displace therealong without contacting any of the individual containers.
According to an aspect, a cutting mechanism for opening and releasing a selected individual container from an array-type pill package is provided, the individual container being one of a plurality of individual containers in the array-type pill package attached to one another and having a common top surface, the plurality of individual containers extending from the common top surface on a same side thereof, the array-type package being mounted onto a package holder supported by a chassis. The cutting mechanism includes: a cutter base movably mounted to the chassis and displaceable relative to the package holder; a cutting tool mounted to the cutting base, the cutting tool being adapted for cutting a side wall of the selected individual container adjacent the common top surface to entirely detach the predetermined individual container from the array-type package; and a cutter motor operatively connected to the cutter base configured to displace the cutting tool in a plane generally tangent to the package holder.
In an embodiment, the cutting mechanism further includes a controller system configured to control a displacement of the cutting tool relative to the package holder along a displacement axis in the plane generally tangent to the package holder.
In an embodiment, the cutting tool includes a cutting blade extending transversely relative to the displacement axis.
In an embodiment, the cutting tool has a transverse length chosen such that the cutting blade simultaneously intersects with opposite side walls of the selected individual container upon displacement of the cutting tool along the displacement axis.
In an embodiment, the cutting blade has a width chosen such that the cutting blade fits within a smallest space between two adjacent individual containers in the array-type pill package.
In an embodiment, the cutting tool is rotatable relative to the cutter base.
In an embodiment, the cutting mechanism further includes a cutter vibration motor operatively connected to the cutter base configured to vibrate the cutting blade transversely.
In an embodiment, the cutting mechanism further includes a worm screw operatively connected to the cutter motor and meshing with a threaded bore extending through the cutter base, the worm screw extending along the displacement axis.
In an embodiment, the cutting mechanism further includes a cutter guide mounted to the chassis and generally parallel to the worm screw, the cutter guide slidably guiding the cutter base therealong.
In an embodiment, the controller system includes limit switches defining first and second end positions of the cutter base along the displacement axis.
In an embodiment, the cutter base includes a dispensing tray below the cutting tool, the dispensing tray being configured to receive the selected individual container after being cut from the array-type package.
According to an aspect, a method for dispensing pills from a selected individual container of a plurality of individual containers of an array-type pill package is provided, the individual containers being attached to one another in an arrangement of rows and columns and having a common top surface, the array-type pill package being mounted in a dispensing system including a chassis, a cylindrical package holder mounted on the chassis rotatably about a longitudinal axis thereof and holding the array-type pill package thereon with the individual containers projecting radially away from said cylindrical package holder, and a cutting mechanism movably mounted to the chassis and displaceable along a displacement axis tangent to the cylindrical package holder. The method includes the steps of: a) rotating the package holder to align an axial zone of the package holder without any individual containers with the cutting mechanism; b) positioning the cutting mechanism along the displacement axis between a column or row of individual containers adjacent the selected container; c) rotating the package holder to position the cutting mechanism adjacent the selected container; d) actuating the cutting mechanism along the displacement axis so as to cut through the sidewalls of the selected container; e) receiving the cut selected container in a dispensing tray connected to the cutting mechanism; f) positioning the cutting mechanism along the displacement axis between a second column or row of individual containers; g) rotating the package holder to align the axial zone of the package holder without any individual containers with the cutting mechanism; and h) actuating the cutting mechanism to displace the dispensing tray to an exterior of the chassis, thereby dispensing the pills while inside the selected individual container.
Further aspects and advantages of the present invention will become better understood with reference to the description in association with the following Figures, in which similar references used in different Figures denote similar components, wherein:
With reference to the annexed drawings the preferred embodiment of the present invention will be herein described for indicative purpose and by no means as of limitation.
Referring to
Although the term pill is used throughout the following description, one skilled in the art would readily understand that the present invention is not limited to the dispensing of medication pills (not shown), but also encompasses the dispensing of any type of objects, and preferably pea-size (small) objects, goods or pellets (such as candies, coffee, tea, seeds or the like) contained in individual containers 14 of the array-type package 12, as shown in dotted lines in the dispensed container 14″ of
The individual containers of the array-type pill package 12 are typically attached to one another in an arrangement of rows and columns and having a common top surface 16. The common top surface 16 is generally flexible and has all of the individual containers 14 extending therefrom on a side thereof. Although seven rows and four columns are shown in the example illustrated in
The dispenser 11 has a main chassis 20 supporting all the other components of the dispenser. A package holder 22 is mounted on the chassis 20 and typically rotates about its longitudinal axis 23 relative to the chassis 20. The holder 22 typically receives and supports at least one, preferably two packages 12 thereon, such that one package can be removed and replaced with another one while the other package is installed to allow a timely dispensing of the pills (not shown) therefrom to the patient.
The dispensing mechanism 10 includes a cutting mechanism 30 operatively connected to the chassis 20 for cutting a side wall 18 of a selected one of the individual containers 14′. Preferably, the side wall 18 is cut adjacent the top wall 16 using a cutting tool 33 mounted to a cutter base 32. In this fashion, the selected individual container 14′ can be entirely detached from the array-type package 12, with the pills remaining inside the original container 14′. A controller system 40 controls a displacement of the cutter base 32 relative to the package holder 22 and the pill package 12. Preferably, the displacement is along at least two degrees of freedom, and can be a two-axis (planar) displacement for example. In this fashion, the controller system 40 can position the cutter base 32 adjacent the selected individual container 14′. In order to achieve a relative displacement of the cutter base 32, the controller system 40 can displace at least one of the cutting tool 33 and the package holder 22 relative to the chassis 20. A dispensing member 60 is operatively connected to the chassis 20 to receive and dispense the cut selected individual container 14′.
In the present embodiment, the holder 22, being typically cylindrical in shape, is typically movably mounted onto the chassis 20 to rotate about its longitudinal axis 23, and thereby as indicated by arrow B in
The cutting mechanism 30 typically includes a cutter base 32 supporting on posts 33′ the cutting tool 33. In the illustrated embodiment, the cutting tool 33 is a sharp cutting blade adapted to entirely cut through the side wall 18 of a selected container 14′ adjacent the top wall 16. The cutting tool 33 and at least the upper portions of posts 33′ are adapted to fit into the smallest space between two adjacent containers 14 of adjacent columns. Any other cutting tool can be considered without departing from the scope of the present invention, such as, but not limited to, a laser beam, a heated wire, etc. The cutter base 32 typically moves along a first axis A, or displacement axis, of the chassis 20, typically linearly, preferably rectilinearly, along a cutter guide 34, as a guiding rod or the like, mounted to the chassis 20 and oriented generally parallel to the longitudinal axis 23, as seen in

Referring still to
Typically, the controller system 40 is also electrically connected to a cutting vibration motor 50 connected to the cutter base 32 to transversally vibrate the cutting tool 33 at the beginning of the cutting operation and facilitate the penetration of the cutting tool 33 into the plastic side wall 18.
In some implementations, the cutter base 32 may include a dispensing member 60 typically including a guiding slide 36 adapted to receive the cut individual container 14′ (with the pills therein) falling thereon. The cutter base 32 may also include a dispensing tray 38, typically located at the front of the cutter base 32 just behind the cutting tool 33, to receive the cut container 14′ sliding from the guiding slide 36 for the selective extraction and dispensing of the pills located into a selected individual container 14′. The guiding slide 36 typically slopes downward towards the dispensing tray 38. To ensure that the cut container 14′ actually reaches the dispensing tray 64 without being stuck on its way, a sweeper arm (not shown) or the like can be connected to the cutter base 32 for pushing the cut container 14′ down to the dispensing tray 38. The sweeper arm or the like may also be activated periodically, at predetermined time intervals, as a cleaning mechanism, to ensure that the guiding slide 36 is free of any object, contamination or debris that could prevent the next cut container 14 from being properly dispensed. After the predetermined container 14′ has been cut and then received into the dispensing tray 38 or receptacle, the cutter motor 46 moves the cutter base 32 towards the front of the chassis 20 with the dispensing tray 38 extending through a dispensing opening 28 formed into the front wall 29 of the chassis 20 to dispense the container 14′ to the user, as shown in
In the present embodiment, the controller system 40 rotates the package holder 22 about longitudinal axis 23 to properly align the cutter base 32 with an axial zone of the holder periphery without any individual containers 14, to then allow the cutter base 32 to move about the first axis A at a predetermined position adjacent the column of the package 12 containing the selected container 14′. The controller system 40 then rotates again the package holder 22 about longitudinal axis 23 to properly align the row containing the selected container 14′ with the cutter base 32 (as illustrated in
Referring back to
Furthermore, in some embodiments the controller system 40 may be connected to a display 54, such as a large interactive touch screen or the like, an external communication device (not shown), such as a port for wire or an antenna for wireless communication with an internet server to send and receive information (to and from a cloud for example), as well as a sound receiver/microphone (not shown) for sound communication, and a light device (not shown) for visual communication, and the like.
Obviously, although not illustrated herein, it would be obvious to anyone skilled in the art, without departing from the scope of the present invention, that, for example, the holder 22 could be generally planar (either curved or flat) and fixed relative to the chassis 20 and that the cutter base 32 could be displaced relative to the holder and the package 12 by two or three different motors along two or three respective axis or along two or three degrees of freedom. Inversely, the cutter base 32 could be fixed relative to the chassis 20, and the motors could displace the holder 22 and the package 12 relative to the chassis 20 and the cutter base 32.
Although the present invention has been described with a certain degree of particularity, it is to be understood that the disclosure has been made by way of example only and that the present invention is not limited to the features of the embodiments described and illustrated herein, but includes all variations and modifications within the scope of the invention as hereinafter claimed.
