Description

PARTS SUPPLYING APPARATUS AND PARTS ARRAY
~;IELD OF THE INVENTION
The present invention relates to a parts supplying a~paldtlls, a parts array used in such an apparatus, and a process for forming a parts array. More 5 specifiç~lly, the present invention pertains to an apparatus for supplying resin molded parts such as pouring attachments that are to be used on containers, an array of resin molded parts such a pouring ~tt~chments, and a process for forming such an aLrray.

l~ACKGROIJND OF lHE ~VENTION
Liquid ho]ltling containers that are made of paper, plastic or the like are typically providecl with a pouring ~tt~chmçnt or pouring spout through which theliquid contents can be dispensed from the container. These pouring attachments are oftentimes molded from plastic m~t~ri~l and subsequently attached to the 15 container. Once attached, the pouring ~tt~hm~nt can then be opened to pour the contents from the c-)nt:~in~r.
An automatic attachment device is utilized to automatically attach the molded resin pou~ing ~tt~rhment to the cont~inçr. These automatic att~t hm~nt devices are de~igned to continuously advance the containers along a conveying 20 path with the pouring att~ hments being secured or attached one by one to the continuously moving containers.
A parts supplying apparatus is typically used to feed the pouring attachments to the automatic attachment device. The parts supplying apparatus isclesigned to align and continuously feed the pouring attachments one by one to 25 the automatic ~tt~ltmçnt device. Conventional parts supplying apparatus are mainly of the vibIating type in which the parts such as the pouring attachments are aligned and fe~ one by one.
Vibrating parts feeders or supplying apparatus include a rail arranged in a spiral shape at a fixed sloping angle. Vibration is applied to the rail while the 30 parts are supplied at one time to the center portion of the rail. The vibration CA 02226764 l998-0l-l3 causes the parts to vibrate and thus align in a row and grA~ ally move down the sloping rail.
However, with the vibrating parts feeder described above, problems exist in that a subst~nti~lly long rail must be used in order for the parts to align in a 5 single row. Additionally, due to the complexity of the shape of the rail and the structure of the overall app~rAtl~, it is difficult, if not impossible, to reduce the size of the apparatus and the costs are prohibitive.
Furthermore, in the case of containers for holding liquids contents for ~lrinking, the pouring attachment to be Att~hçd to the container must be in a 10 hygienic or sterile state. However, when utili7ing a vibrating parts feeder such as that described above for feeding the pouring attachments for subsequent ~tt~chmçnt to the container, it is possible for foreign objects to cling to the pouring Att~chmPnts as the pouring attachments gr~ lly move down the rail.
These foreign objects on the pouring ~tt~chmçnt~ can adversely affect the sterility 15 of the containers when the pouring ~tt~chmçnt~ fed by the vibrating parts feeder are subsequently Att~hed to the containers.
In addition to the problems i~lçntifiecl above, vibrating parts feeders of the type described above suffer from the disadvantage that although the feeders can align the parts to some extent, situations arise where the vibratory action is not 20 entirely effective to produce a well formed row of parts. Also, problems havearisen in the context of using the feeders to feed parts having different shapes.
In this regard, portions of the vibratory parts feeder may not be well suited to the particular shape of the parts being fed and so difficulties arise in properly ~ligning the parts in a row, Thus, it has been found necessary in some instances25 to perform tests and effect design alterations in the feeder to address such problems.

WO 97/03884 PCTI'US96~;1997 SUMMARY OF THE INVENTION
In light of the folegoillg, a need exists for a parts supplying apparatus as well as a parts array that permits realization of cost re~luctiQn~ and size reductions of apparatus suitable for feeding parts.

DETAILED DESCRIPrIQN OF THE INVENTION
With reference initially to FIG. 1, the parts supplying apparatus according to the present invention is designed to feed a parts array 10 in the form of a 30 plurality of pouring spouts or pouring attachments 11. The pouring attachments WO 97/03884 PCrJUS96~11997 are attached to a pair of wires 31 and 33 that are disposed generally parallel to one another. The pouring ~tt~hmPnt~ 11 are molded articles and are ~tt~,hçd to the wires 31, 33 in a row to form an elongated strip or parts array of pouring ~tt~chmP,nt~ 11. As can be sen in FIGS. 1 and 2, the pouring ~tt~hmPnt~ 11 are S disposed in the parts array 10 in subst~nti~lly the same vertical orient~tion with respect to one another.
As seen with reference to FIG. 4, the pouring ~tt~c,hments 11 each include a base 167 an opening portion 15 that is adapted to effect opening of the container to whichl the ~tt~hment is secured, and a lifting part 13 that causes the 10 opening part 15 to perform the opening operation throu,gh lifting action. Theunderside of each of the pouring attachments 11 is attached to the two parallel wires 31 and 33. The wires 31 and 33 are preferably integrally attached and formed with the resin molded pouring ~ttachmçnt~ 11 when the attachments 11 are molded by pla,cing the wires 31, 33 into the molding die. The wires 31, 33, 15 which can be made of plastic or metal such as steel, constitute a carrier forcarrying the pouring attachments 11 and forming the pouring ~tt~,hment array 10.
The wires 31, 33 are ~tt~chPd in the vicinity of the exterior underside surface of the pouling attachments 11 so that the wires 31, 33 can be removed 20 from the pouring :ltt~çhmP,ntc 11 by pulling the wires away from the pouring ~ttaçhments. The wires 31, 33 ~ttaçhPd to the pouring ~ttaçhmçnts are spaced apart and preferably positioned adjacent opposite ends of the pouring attachments as shown in FIG. 4.
FIG. S illustrates the pouring ~tt~hment 11 separated from the wires 31, 25 33 and attached to the top of a container 20 formed from paper, plastic or the like. FIG. 8 also illustrates the pouring spout 11 attached to the top of a container. The pouring attachment can be secured to the container 20 by an automatic setting a,pparatus which is not specifically shown. More specifically,the pouring attachment 11 is ~tt~ched to a sealing sheet (not speçif;ç~lly shown in 30 the drawing figures) that has been previously adhered to the container 20 to close or seal the container opening 21 formed in the top of the container 20. The opening 21 in the container 20 is then opened by pulling up on the lifting part 13 of the pouring ~tt~chmPnt 11 as shown in FIG. 5. This causes the opening part 15 to pivot down into the container opening 21, thus breaking the sealing sheet 5 extending over the container opening 21.
Turning once again to FIG. 1, the parts supplying a~aldlus includes a winder arrangement 40 that is comprised of a motor 41, a winding drum 43, a winding position adjuster 45, two spaced apart guide rollers 47, 49, and two spaced apart guide plates 51, 53. The motor 41, the winding drum 43, the winding position adjuster 45, the pair of guide rollers 47, 49, and the pair of guide plates 51, 53 are all generally vertically ori~nte~l and disposed substantially parallel to one another. The motor 41, the winding drum 43 and the winding position adjuster 45 extend through respective openings in a first plate member 42 while the pair of guide rollers 47, 49 and the pair of guide plates 51, 53 are lS disposed on a second plate member 44 that is spaced above the first plate member 42.
The motor 41 possessec a rotary axle 55 that is coupled to the rotary axle 59 of the winding drum 43 via a horizontally disposed belt 57. The winding position adjuster 45 includes a rotary body or shaft 65 whose end is provided with a gear 63. The end of the rotary axle 59 is also outfitted with a gear 61.
The gear 61 on the rotary axle 59 and the gear on the rotary body 65 engage one another. In this way, rotary movement of the motor 41 is transferred to the winding drum 43 and to the rotary body 65 of the winding position adjuster 45.
In addition to the rotary body 65, the winding position adjuster 45 is comprised of a generally vertically oriented support member 67 which supports and permits free rotation of the rotary body 65 and a vertically movable arm member 69 that is movable along the length of the rotary body 65. The support member 67 is provided with a groove 73 extending along the surface of the support member 67 that faces the rotary body 65.

WO 97/1)3884 PCT/US96~11gg7 The outer peripheral surface of the rotary body 65 is provided with spiral grooves 71 that are engaged by a pin (not specifically shown) which is located in a through hole in the movable arm member 69. The arm member 69 in~hldes a generally horizont~lly erten~ling projecting portion 69a having a free end that S engages the vertical groove 73 of the support member 67 in such a way that the projecting portion 69a is guided over a vertical movement path. The projecting portion 69a is also formed with a generally horizontally elongated hole 75 through which is ,adapted to pass the pair of wires 31, 33.
As shown in FIG. 3, the first guide plate 51 is formed with two small holes 77, 77 and Ithe second guide plate 53 is similarly formed with two small holes 79, 79. The holes 77, 77, 79, 79 are adapted to permit the passage of the pair of wires 31, 33 with the wires 31, 33 initially passing through the first guide plate 51 and subsequently through the second guide plate 53 located downstream of the first guide ]plate 51 with respect to the direction of travel of the wires 31, 33. The distance between the pair of holes 79, 79 in the second guide plate 53 is smaller than that between the pair of holes 77, 77 in the first guide plate 51, thereby causing th.e wires 31, 33 to approach one another as they pass from the first guide plate 51 to the second guide plate 53.
As shown .in FIG. 2, the ~paldtlls further includes an array guide member 80 for guiding the array 10 of interconnected pouring ~tt~chments 11.
The guide membe.r 80 is an P1ong~ted, slender box-shaped element provided with a guide hole or guide passage 81 that extends along the length of the guide member 80. The guide hole 81 is sized to accommodate therein the pouring attachment array ]Ø
As can be seen from FIG. 3, the guide member 85 is provided with a pair of outlet holes 85 ~hat communicate with the guide hole 81. The outlet holes 85 t extend through the guide member side wall 84 that faces towards the first guide plate 51. The inside surface of the guide member side wall through which the outlet openings extRnd con~titutes the guide surface 83 for the guide member 80.
-As shown in FIGS. 2 and 3, the two outlet holes 85, 85 serve as a drawing arrangement through which are drawn the two wires 31, 33 from the pouring attachment array 10 passing through the guide hole 81 in the guide member 80. Furthermore, on the side wall 86 of the guide member 80 opposite the side wall 84 in which are located the outlet holes 85, 85 is provided with agenerally horizontally elongated hole 87. This elongated hole 87 is adapted to receive a portion of the outer periphery of a rotary array advancing body 89 that is positioned adjacent the guide member 80.
The pouring attachments 11 on the array 10 are introduced into the longit~l~lin~lly extending hole 87 and are pushed against the guide surface 83 of the guide member 80 by the rotary body 89 that is adapted to freely rotate aboutan axle 91. The rotational axis of the rotary body 89 is generally vertically oriented and the rotary body 89 lies in a plane that is generally perpendicularly oriented to the plane of movement of the array 10. The outer peripheral surface of the rotary body 89 is provided with projections 93 that are spaced apart fromone another by a pitch that is approximately the same as the spacing between adjacent pouring attachments 11 on the array 10.
The wires 31, 33 that are separated from the pouring attachments 11 and fed through the outlet holes 85, 85 in the guide member 80 are fed to the winder40 by way of the pair of guide rollers 47, 49 that are positioned downstream of the first guide plate 51 and the second guide plate 53 with respect to the direction of advancement of the array 10. The two guide rollers 47, 49 are mounted for free rotation on the second plate member 44. The rotational axes of the guide rollers 47, 49 are substantially parallel to one another and to the rotational axis of the array advancing rotary body 89.
The following is an explanation of the operation of the parts supply apparatus. When the motor 41 is rotatably driven, the winding drum 43 starts to rotate via the belt connection 57. At the same time, the rotary body 65 rotates through the interenp~ging gears 61, 63. The rotation of the rotary body 65 causes the arm member 69 to move axially up and down along the length of the -WO 97/03884 PC~/US96J11997 rotary body 65 through the engagement between the pin (not specifically shown) on the arm member 69 and the spiral grooves 71 on the rotary body 65.
Due to the rotation of the winding drum 43, the wires 31, 33 are pulled through the holes 85 in the guide member 80 in the direction indicated by arrow 5 A in FIG. 2. This causes the pouring attachment array 10 to moves through the guide passage 81 of the guide member 80. At the same time, the portion of the peripheral surface of the rotary body protruding through the opening 87 of the guide member 80 and into the guide passage 81 presses the array 10 into contacting engage:ment with the guide surface 83 of the guide member 80.
The foregoing operation also effects separation of the wires 31, 33 from the pouring ~tt~rhm~nts 11. With the rotary body 89 pushing the pouring attachment array L0 against the guide surface 83 of the guide member, the wires 31, 33 ~tt~ched to the pouring ~tt~chment.~ 11 peel away from the ~tt~chments 11and are drawn out through the outlet holes 85, 85 on the guide surface 83. The separation of the wires 31, 33 from the pouring attachments can proceed rather easily because the array 10 is pushed against the guide surface 83 by the rotarybody 89.
Once separated from the wires 31, 33, the pouring attachments 11 are discharged from the guide member 80 to the outside and are fed one by one to an automatic setting apparatus (not specifically shGwn) by a feeding device (not specifically shown)l such as a chute or a manipulator arm. All of the separated pouring attachments 11 face in the same direction or are oriented in the same manner, and there is no possibility that any of them will be turned upside down.For this reas~n, it is possible to accurately attach the pouring attachments 11 to the proper place on a container such as shown in FIG. 5 As the two wires 31, 33 are drawn out from the outlet holes 85, 85 and are passed through the small holes 77, 77, 79, 79 provided in the two guide plates 51, 53, the wires 31, 33 converge together as shown in FIG. 3 by virtue of the smaller spacing between the holes 79, 79 in the second guide plate 53.
The wires 31, 33 are then conveyed over the guide rollers 47, 49 and are CA 02226764 l998-0l-l3 directed to the winding position adjuster 45 where the converged wires 31, 33 pass through the opening 75 in the projecting portion 69a of the mounting arm '-69. The wires 31, 33 are then finally wound around the winding drum 43 as shown in FIG. 1. The mounting arm 69 which is moving vertically along the 5 winding drum to produce generally even wound layers of wires.
The parts array 10 according to the present invention can be delivered to the parts supply apparatus as shown in FIG. 1 in a sterile condition since the pouring ~tt~hments 11 and the wires 31, 33 are simultaneously molded as one unit and due to the array 10 being in a sealed box. Moreover, only the guide member 80 and the rotary body 89 contact the parts array 10, and so it is only necess~ry to sterile these two elements. Thus, it is possible to easily keep thepouring ~tt~chmçnts 11 in a hygienic or sterile condition without great difficulty.
Fig. 6 illn$trates an ~ltPrn~tive embodiment of the pouring ~tt~chment or parts array 10' . The pouring ~tt~hmPnt 11 is of the same general type as that described above, but in this alternative, the carrier on which the ~tt~chments 11 are disposed is in the form of a tape 131. The tape 131 preferably possesses a width sufficiently wide that the entire ~tt~hmçnt is positioned on the tape 131.The tape 131 is rather thin so that the thicknP-ss of the tape is much less than the width of the tape 131.
The pouring ~ttachment~ 11 are att~ch~d or secured to one surface of the tape 131 preferably by inle~ tly injecting thermoplastic resin at spaced apart locations on the tape 131 corresponding to the locations of the atta~hm~nt~ 131.For e~r~mple, the portion of the carrier (e.g., tape 131) corresponding to the location of the pouring ~st~hm~nt is placed on a flat wall of a first molding die.
The portion of the carrier is then placed between the wall of the first molding die and a second molding die which is pushing from above the surface of the carrier.Thereafter, thermoplastic resin is injected onto the carrier to mold or form an ta-~hmPnt After the injection step, the second mold is removed from the attachment that has been molded on the carrier, and the carrier is shifted with the integrally molded ~tt~ hment by the mP~ec~ry spacing between ~tt~chmPnt~ so wo 97/a3884 PCT/US96/11997 that the next pouring ~tt~chm~nt can be molded. This process is advantageous as it l~ sellts a reLatively efficient manner of making an aseptic parts array.
FIG. 7 is aL perspective view of a portion of the parts supplying a~aldLus used in conjunction with the parts array 10' shown in FIG. 6. As can be seen, 5 the apparatus is ~uite similar to the apparatus described above, except that several parts of the al~pa,~ s are modified to accommodate the tape carrier shown in FIG. 6 rather than the plural wire calTier shown in FIG. 4. In particular, the first and second guide plates S1 ', 53' are each provided with an opening that is elongated in the vertical direction to accommodate the shape of the tape 131. It is also envisioned that the guide rollers 47', 49' need not be provided with a groove for receiving the tape as in the case of the embodiment of the apparatus shown in FIG. 3. Rather, the guide rollers 47', 49' can possess a cylindrical outer surface as generally shown in FIG. 7. Finally, although not specifically shown in FIG. 6, the elong~tt-d slot 75 in the projecting portion 69a of the mounting arm 69 (see FIG. 1 should preferably be oriented in the verticaldirection to once a~ain accommodate the configuration of the tape 131. The operation of the embodiment of the apparatus depicted in FIG. 7 is the same as that described above.
The presenl: invention provides a parts supplying apparatus and parts array po~sessing a variety of advantages and desirable attributes. For example, a reduction in the size and cost associated with the parts supply apparatus can berather easily achie~ed. Also, the design of the apparatus is well suited to ensuring minim~l contact with the parts array so it is possible to m~int~in the sterility of the parts. Further, the parts supply apparatus of the present invention helps ensure accurate orientation of the.parts removed from the parts array.
It is unders~:ood that variations with respect to the above described embodiments may be employed. For example, the present invention is applicable to resin molded parts other than the pouring spout or pouring attachment used inconjunction with containers. Also, in the above described embodiment, the guide hole 81 is providecl in the guide member 80 and the guide surface 83 is provided wo 97t03884 PCT/US96/1 l 997 to one surface of the guide hole. In the context of the present invention, as long as the guide surface 83 is present, the guide hole 81 is not neceSs~ry. The structure need only be such that at least one surface of the parts array is in contact with a guide surface that guides the movement of the parts array and a 5 drawing means is provided at a fixed position on the guide surface to draw thewires for a parts array in a direction away from the pouring ~tt~chments or other molded parts. Additionally, it is envisioned that the carrier illustrated in FIG. 4 is not limited to two wires, but can be in the form of three or more wires.
The principles, preferred embodiments and modes of operation of the 10 present invention have been described in the foregoing specification. However, the invention which is intended to be protected is not to be construed as limited to the particular embodiments disclosed. Further, the embodiments described herein are to be regarded as illustrative rather than restrictive. Variations and changes may be made by others, and equivalents employed, without departing 15 from the spirit of the present invention. Accordingly, it is expressly intended that all such variations, changes and equivalents which fall within the spirit and scope of the present invention as defined in the claims be embraced thereby.
