The packaging machine demarcates upper and lower boundaries about the item such that the enclosed item may be separated from a continuously produced strand of packages. The packaging machine includes a selectively operable hole punch portion disposed adjacent the strand of packages for providing a hole in a portion of each package. The hole punch portion includes a punch driving member which is disengable responsive to unexpected resistance encountered by the punch. A cutter/stacker portion adjacent the strand of separable packages separates the strand into individual packages and stacks the packages in a removable magazine. The magazine has a rod member onto which the packages are inserted with the rod member extending through the hole in each package. A printer can be included for printing indicia on one side of one of the continuously fed strips of packaging material to provide information regarding the enclosed item.
Description




BACKGROUND




This invention relates generally to packaging machines which enclose items between strips of material and, more particularly, to a packaging machine for enclosing medicine in packages which can be separated and stored in a removable magazine.




Bulk packaging machines which can separate and individually package a quantity of items and produce individual packages are known in the art, particularly bulk packaging machines which have been heretofore used to package medicine, such as capsules, caplets and tablets. One such prior art pill packaging machine can be used to separate and individually package large quantities medicines such as tablets or capsules. This bulk packing machine includes components demarcating upper and lower boundaries of packages, such as by scoring or perforating, such that a strand of individually separable packages are produced which can later be manually separated. Such a bulk packaging machine includes a top tray portion for separating a quantity of loose capsules, tablets, or other solid items, into individualized compartments and feeding each capsule individually, such as through a chute, into a position where it can be individually enclosed in a sealed package. Of course, the tray portion could also be configured to separate the loose capsules into pairs, or larger groups. Generally, two rolls of packaging material are positioned at opposite ends of the bulk packaging machine and are fed towards each other into an adjacent relationship at a packaging portion of the bulk packaging machine. At the packaging portion, the two strips of material are brought together in an adjacent position and joined together about a perimeter of the item to create an individual package. The packaging portion has a closure member, which is a generally horse-shoe shaped fixed frame on one side of the packaging portion and a correspondingly shaped movable frame positioned opposite the fixed frame for movement against the fixed frame. Either or both the fixed frame or the movable frame can be heated. When the movable frame is moved into contact with the fixed frame, with the two strips of packaging material sandwiched therebetween, the packaging material will be joined together by pressure and heat. The bulk packaging machine can further include a control unit for operating the device and a printer for printing information on one side of one of the strips of packaging material which is indicative of the type of medicine enclosed.




A disadvantage of the prior art bulk packaging machines is that the individual packages must be manually separated from the continuous strand of packages produced. Furthermore, packages made on such machines have been sealed around the edges having little room to punch a hole through the package without opening the pocket containing the pill or capsule, or being too close to the edge. Consequently, such packages are not suitable for punching and hence, cannot be stored on a rack. Therefore, they cannot be handled by an automated pharmacy such as is disclosed in U.S. Pat. No. 5,593,267. In an automated pharmacy there is also a need for the hole to be in an accurate location with reference to the formatted barcode. Accordingly, there is a need for a bulk packaging machine which can simultaneously produce a strand of enclosed packages, punch a hole through each individual package in an accurate location with reference to formatted barcode, separate the individual packages from the strand, and store separated packages in a magazine. Moreover, this packaging machine should be designed so that if the pill or other object being packaged does not fall completely into the package and is struck by the by the punch, components of the punch driving mechanism will release preventing damage to the punch. Should this occur, the punch driving mechanism should be easily reset to avoid a lengthy shut down of the machine.




SUMMARY




A packaging machine is provided for enclosing items in a package and then separating and storing the packages in a magazine. The packaging machine delivers individual items, such as medicine, through a feeder that disposes the item between two strips of packaging material. A closure member then joins the two strips of packaging material together around the item, thus sealing the item in an individual package. The packaging machine also has a demarcating member which demarcates upper and lower boundaries about the item such that the enclosed item may be separated from a continuously produced strand of packages. The packaging machine also includes a magazine for storing individual separated packages, a hole punch member, a separator member, a stacker member, and a magazine wherein the separated packages are stored. The hole punch member is disposed adjacent the strand of packages for punching a hole in a portion of each package. The hole punch member preferably includes a driving arm portion which is frictionally engaged with a member that drives the punch. The frictional engagement is designed such that if the punch encounters a certain degree of resistance, such as from striking a relatively hard object, disengagement of the driving arm and the member that drives the punch will occur without damage to any components. Operation can then be more quickly resumed since the only repair necessary is to re-engage the disengaged members. The separator member is located adjacent the strand of separable packages and the stacker member. The separator member separates the strand into individual packages which are then placed in the magazine by the stacker member. The magazine, which is preferably removable, includes a rod member on which the stacker member inserts the packages, with the rod member extending through the hole provided in each package by the hole punch member. A printer and a printer control unit can also be included for printing indicia on one side of one of the continuously fed strips of packaging material to provide information regarding the enclosed item.




Other details, objects, and advantages of the invention will become apparent from the following detailed description and the accompanying drawings figures of certain embodiments thereof.

DETAILED DESCRIPTION OF CERTAIN EMBODIMENTS




To aid in understanding the presently preferred embodiments it will be helpful to first describe a prior art bulk packaging machine and, more particularly, a bulk packaging machine which has been heretofore used to package medicine, such as capsules and tablets. Referring to

FIG. 1

, there is shown such a prior art bulk packaging machine


1


for enclosing items, such as capsules and tablets, in separately enclosed packages which may be produced in bulk. The bulk packaging machine


1


can score, or perforate, upper and lower boundaries of the enclosed items such that a continuous strand of individually separable packages is produced. The packaging machine


1


also has a top tray portion


3


for separating a quantity of loose items into individualized compartments


4


to thereby separately feed each item, such as through a chute, into a position where it can be individually enclosed in a sealed package. The tray portion


3


could also be configured to separate the loose items into pairs, or larger groups. Also shown are two supplies of packaging material, such as the rolls of packaging strips


5


,


7


positioned at opposite ends of the bulk packaging machine


1


. The two strips of packaging material


5


,


7


are fed towards each other into an adjacent relationship at a packaging portion


9


of the bulk packaging machine


1


. At the packaging portion


9


, the two strips of packaging material


5


,


7


are brought together into an adjacent relationship and then sealed together to enclose the items in individual packages. The packaging portion


9


typically includes a closure member, such as a generally horse-shoe or A-shape fixed frame on one side of the packaging portion


9


and a correspondingly shaped movable frame positioned opposite the fixed frame for movement thereagainst. Either the fixed frame or the movable frame, or both, can be heated so that when the movable frame is moved into contacts with the fixed frame, with the two strips of packaging material


5


,


7


sandwiched therebetween, the two strips of packaging material


5


,


7


will be joined together along the edges which are pressed together and heated by the two frame members. In this manner, the two strips of packaging material


5


,


7


are joined together along a perimeter and across the center thereby enclosing the item in a package.




The bulk packaging machine


1


can also include a printer and a control unit (neither shown). The control unit may be programmable and may be used to control one or both of the bulk packaging machine


1


and the printer. The printer can be employed to print information on a side of one of the strips of packaging material


5


,


7


. Information regarding the packaged item can be stored in the control unit, or in printer memory if available, and the printer


13


can print such information on the side of one of the strips of packaging material


5


,


7


. The bulk packaging machine


1


can also include a cutter or a demarcating portion


15


, which can cut, perforate or score the joined together strips of packaging material at upper and lower boundaries of the enclosed items. Scored or perforated strips of packages of enclosed items may be manually separated into individual packages by tearing the continuously produced strand of packages along the perforations or score lines. Although the bulk packaging machine


1


may have various other features or modifications, those features described above are typical of the primary components of prior art bulk packaging machines.




Referring now to

FIGS. 2 and 3

, there is shown a presently preferred embodiment of a packaging machine


20


which, in addition to several new features, may include most, or all, of the conventional components of the prior art bulk packaging machine


1


described in connection with

FIG. 1

, such as a display and control unit


26


, which may be programmable, and a printer


29


. Additionally, the packaging machine


20


includes a top tray portion


23


which separates a quantity of loose items to be enclosed in individual packages. The items are separated, by vibrating the top tray portion


23


or manually placing the items into individual compartments


24


of the top tray


23


, which individually deliver the items, for example, through chutes communicating with the underside of compartments


24


, to a packaging portion


41


. It should be understood that the items can also be separated into groups of two, or more, instead of individually. Typically, two supplies of packaging material, such as rolls


32


and


35


containing strips of packaging material, are fed towards the packaging portion


41


, such as by a series of rollers, including rollers


42




a


,


42




b


. The packaging machine


20


may also include a feeder portion


38


, having roller


43




a


and


43




b


, which may be powered. The rollers, including


43




a


,


43




b


,


42




a


, and


42




b


, draw and guide the two strips of packaging material


32


,


35


into an adjacent relationship through the packaging portion


41


. The packaging portion


41


further includes a closure portion


45


having die set members


70


and


76


, shown in

FIG. 4

, and a heater unit


47


shown in FIG.


2


. The movable die


70


is shown in more detail in FIG.


4


. The bulk packaging machine also includes a hole punch portion


46


, having a hole punch


80


and hole punch driving portion


100


, shown in

FIGS. 5 and 6

respectively. The printer


29


prints indicia on at least one side of at least one of the strip of packaging material


32


. This indicia usually would include a bar code and other information about the item which is enclosed in the package.




The packaging portion


41


shown also includes a demarcating member


50


which preferably is designed to cut, but can also be suitably designed to score or perforate, the joined together packaging material at upper and lower boundaries of the enclosed item. The packages can thus be separated automatically, or a strand of individually separable packages of enclosed items can be produced. The packaging machine


20


shown also includes a cutter/stacker portion


44


and an associated magazine


200


. The cutter/stacker portion


44


is positioned along the feed path of the strand of enclosed items, at a location subsequent to the demarcating member


50


. The cutter/stacker portion


44


separates the strand into individual packages. The demarcating member


50


can simply be a blade which cuts, such as by a scissor-type action, the joined together packaging material about upper and lower boundaries of the enclosed item. The cutter/stacker portion


44


then stacks the separated packages in the magazine


200


. The cutter/stacker portion


44


, although shown as a single portion


44


at the same location, could also be separate members and could be positioned at different locations. The magazine


200


is shown and described in more detail in FIG.


7


and is preferably removable such that when the magazine


200


is filled it can be removed and replaced with an empty magazine.




A rear view of the bulk packaging machine


20


is shown in

FIG. 3

, illustrating a main drive motor


58


which operates a feed drive


61


. The feed drive


61


controls the delivery of each item to be enclosed by the packager portion


41


. Also shown are a pair of control boards, including a main circuit board


54




b


and a printer circuit board


54




a,


associated with the control unit


26


and the printer


29


, respectively. A power supply connector


51


is provided for connecting the bulk packaging machine


20


to an AC power source. At the lower left portion of

FIG. 3

, the rear portion of the magazine


200


can be seen extending upwardly towards the cutter/stacker portion


44


.




Referring to

FIGS. 2 and 4

, the closure portion


45


includes a die set such as fixed die or seat member


76


and movable die or closure head


70


, which are employed to join the two strips of packaging material


32


,


35


together about the item, thereby enclosing the item in a package. Each die


70


and


76


can be fashioned with an intermediate portion


73


as shown on die


70


in FIG.


4


. As can be seen in

FIG. 2

, the dies


70


and


76


are disposed opposite each other with a gap therebetween through which the two strips of packaging material


32


,


35


are fed in an adjacent relationship in order to be sealed together by the closure portion


45


. The dies


70


and


76


are appropriately sized such that when the movable die


76


is moved against the fixed die


70


, the dies


70


and


76


contact each other along mating surfaces thereof. When the two strips of packaging material


32


,


35


are placed between the mating surfaces they are thereby joined together along the generally horse shoe shape of the dies


70


and


76


. To accomplish the joining together of the two strips of packaging material


32


,


35


, moveable die


76


is heated by heater


47


and the two strips of packaging material


32


,


35


are selected such that the heat causes the two packaging strips to be joined together. Preferably, the stationary die


70


is not heated. We prefer to provide a cavity


71


in die


70


that receives a gasket


77


. The strip of packaging material is pressed against the gasket


77


as movable die


76


closes against die


70


.




The closure member is selectively configurable to enclose a single packaged item in a larger package


220


with a hole


224


punched in the package, shown in

FIG. 8

, or generally twice as many smaller packages


230


which do not have a hole, as shown in FIG.


9


. Essentially, the larger package


220


is two smaller packages, one filled and one empty, and the hole is punched in the empty package. The selection is made by making an adjustment to a portion of the hole punch driving mechanism


100


in a manner described in detail below in connection with the description of FIG.


6


. Additionally, operation of tray


23


is adjusted to control the rate at which product is fed between the packaging material


32


,


35


positioned within the closure portion


41


. Initially, the packaging material


32


,


35


is fed through the closure portion and the die set


70


,


76


are operated to seal the material together. At this point no item has been dispensed yet. Thus, only the bottom side of the next package has been sealed. In the next step, an item is dispensed between the packaging material


32


,


35


and the packaging material


32


,


35


is then fed a certain distance. The dies


70


and


76


are closed, this time sealing the other three sides of the package thereby completely enclosing the item. The distance the packaging material


32


,


35


is fed depends on whether or not it is desired to produce the large package


220


or the small package


230


. If small packages are being filled, the distance the packaging material


32


,


35


is fed after the item is dispensed therebetween is only the distance required to position the item in an upper enclosure region


72


, between the top of the die set


70


,


76


and the intermediate portion


73


. When the dies


70


,


76


are then brought together, the top of the dies and the sides thereof completely enclose the item within the upper enclosure region


72


shown in FIG.


4


. However, if a hole is to be punched in the package, the packaging material


32


,


35


is fed farther, generally twice the distance as the material was moved to create the small package, such that the dispensed item is positioned below the intermediate portion


73


in a lower enclosure region


74


. In this case the intermediate portions


73


and the side of the dies


70


,


76


below the intermediate portions


73


will seal completely around the item in the lower enclosure region


74


. Moreover, the top of the dies


70


,


76


and the sides thereof above the intermediate portions


73


will also seal about the upper enclosure region


72


. In this case, a hole will be punched in upper region


72


by the hole punch portion


80


. The distance the packaging material


32


,


35


is moved, in relation to dispensing the items and operation of the closure portion


41


, can be controlled by the speed at which the packaging material


32


,


35


is fed.




In addition to the conventional hole punch portion, a hole punch portion


80


according to the invention, as shown in

FIG. 5

, preferably includes a linkage in the drive mechanism


100


, shown in

FIG. 6

, which prevents damage to components of the punch portion


80


and drive mechanism


100


if resistance is encountered by the punch


82


member. The hole punch portion


80


of the packaging portion


41


can also include a punch guide block


88


and a plate


94


containing slug tube


93


which receives the punched out portion of the package. The sealed adjacent strips of packaging material


32


,


35


are fed between block


88


and tube


93


. The punch


82


is aligned with a guide hole


90


in a punch guide block


88


for driving movement therethrough in order to punch a hole though the portion of the two strips of packaging material


32


,


35


as they are fed past the punch guide block


88


. A sleeve


84


and return spring


86


may be positioned over the punch


82


in order to retract the punch


82


once it has been driven through the guide hole


90


to punch a hole in a package. Additionally, a die plate


92


can be provided in the opening


89


in alignment with a second guide hole


91


to further facilitate the punching of the hole through the two strips of packaging material


32


,


35


.




The punch driving mechanism, shown in

FIG. 6

, includes a drive arm


107


which has seat


113


that engages the head of the punch


82


shown in FIG.


5


. The main drive arm


107


is attached to moving mounting block


108


by bolt


111


and through slot


114


. The mounting block


108


is connected to one of the sealing dies. The pin


110


captured in the slot


106


of the clip portion


105


attaches driving arm


102


to arm


107


. Arm


102


has two slots


103


and


104


either of which can be used to connect arm


102


to pin


112


. As pin


112


reciprocates arm


102


moves back and forth causing arm


107


to reciprocate. When arm


102


is engaged to pin


112


through slot


104


, seat


113


will engage punch


82


pushing to forward as arm


107


advances. As arm


107


moves backward, spring


86


returns the punch to its original position. According to a preferred embodiment of the invention, arm


102


is made of a plastic such as Delrin plastic. The slot


106


and clip portion


105


are designed to flex and permit the pin


110


to disengage, by spreading the clip portion


105


enough to release the pin


110


from the slot


106


, in the event that a certain degree of resistance is met by the punch


82


during the hole punching operation. In this manner, instead of any components breaking, the arm


107


driving punch


82


simply disengages from the punch driving arm


102


. The only repair necessary to resume packaging is to reengage the pin


110


with the driving arm


102


by reinserting the pin


110


into the slot


106


in the clip portion


105


. The setting in slot


104


is used when making the large package shown in

FIG. 8

which is punched.




To make the small package of

FIG. 9

, one moves arm


102


so that pin


112


is in slot


103


in the forward portion of the punch driving arm. As a result, the bottom of arm


102


will have been moved rearward such that seat


113


will not contact driving punch


82


. By positioning pin


112


in slot


103


, the seat


113


on arm


107


either never engages the punch


82


, or if it does engage the punch, the result is that the punch


82


is not moved forward sufficiently to reach the package when it is operated and thus no hole will be punched through the package.




A presently preferred embodiment of a magazine


200


is shown in

FIG. 7

having a rod


202


adapted to removably receive a rod tube


204


thereover. The rod tube


204


can have a specially configured tip member


208


which is designed to facilitate the insertion thereover of individual packages, such as packages


216


,


218


,


220


, via a hole


224


punched in each package


216


-


220


. The magazine


200


includes a housing


206


and a handle


210


. The housing


206


is received in a tray


212


which is attached to the bulk packaging machine


20


. A plurality of packages, such as packages


216


-


220


, can be disposed into the magazine


200


over the configured tip member


208


and stored on the rod tube


204


. When filled with packages, the rod tube


204


, with the packages held thereon, can be removed from the magazine


200


simply by slipping the rod tube


204


off of the rod


202


. An empty rod tube


204


may then be placed over the rod


202


and the magazine


200


can then be refilled with packages. In this manner, the bulk package machining


20


can enclose, separate and stack multiple packages of items almost continuously, multiple packages of items almost continuously, while storing them in the magazine


200


on the rod tube


204


which can be removed when filled and replaced with an empty rod tube


204


.




Additionally, a linkage


214


is preferably provided which attaches the tray


212


to the bulk packaging machine


20


. The linkage


214


is designed to permit the tray


212


, which holds the magazine housing


206


, to pivot allowing the packages to drop from the machine rather than be loaded onto tube rod


204


. This is particularly useful during set-up of the machine. These packages could be left over from the previous packing run and are the ones between printer


29


and cutter


44


. This makes it faster and easier to remove the rod tube


204


, with the packages thereon and to replace an empty rod tube


204


back over the rod


202


so that the magazine


200


may be refilled. In addition, this action allows a number of packages to be purged.




Although the strips of bulk packaging material


32


,


35


are shown as being generally flat, it should also be understood that one or both of the strips of packaging material


32


,


35


could have contours or raised portions. Accordingly, packages produced by the bulk packaging machine


20


could be blister packages having sloped raised formations as described in U.S. Pat. No. 5,878,885. Furthermore, the height of the blister or raised portion surrounding the pill or capsule within the package will vary among different medications. For example, an 800 mg Ibuprofen tablet is much larger than a 200 mg Ibuprofen tablet. Accordingly, the number of packages that can be held on the rod tube


204


may differ according to what is being packaged. We prefer to provide software within the control unit


26


having a selector such as knob


16


that allows the operator to enter or select the type of medicine being packaged. Once that selection is made, the software will determine the number of packages of that medicine that can be held on the rod tube. That determination is based upon the thickness of each package which depends upon the thickness of the selected medicine and the length of the tube rod


204


. The software can also determine the size package to use. The information may be in a look-up table. The software further enables the controller to count the packages as they are being made, signal when the tube rod


204


is full or nearly full and stop the packages when sufficient packages have been made to fill the tube rod. Then, the operator removes the packages from the tube rod or replaces the filled rod with an empty rod and restarts the packager.




Although certain embodiments of the invention have been described in detail, it will be appreciated by those skilled in the art that various modifications to those details could be developed in light of the overall teaching of the disclosure. Accordingly, the particular embodiments disclosed herein are intended to be illustrative only and not limiting to the scope of the invention which should be awarded the full breadth of the following claims and any and all embodiments thereof.
