GLEASON ATTORNEY United States Patent 3,148,762 APPARATUS FDR ORIENTING ELONGATED TAlLEl) GBEECTS Fred C. Gleason, Cannondale, (101111., assignor to American Home Products Corporation, New York, N.Y., a

corporation of Delaware Filed Mar. 12, 1962, Ser. No. 178,996 23 Claims. ((1. 198-33) This invention relates generally to apparatus for orienting objects of substantially similar configuration. More particularly, the invention relates to apparatus for automatically orienting a series of elongated objects each consisting essentially of a structural enlargement at one end and a tail portion extending from said enlargement.

Although not restricted thereto, the invention is particularly useful for orienting aerosol-valves comprising a cap and a dip tube dependent therefrom, preparatory to automatic insertion of said valves into aerosol cans or containers conveyed on a feed line. With the ever-widening acceptance of the packaging of fluid products in aerosol containers, it has become an increasingly greater problem to provide dependable, rapidly operating, substantially fully automatic means for such preparatory orienting of large quantities of aerosol valves, to replace conventional laborious, time-consuming and costly manual operations. Moreover, increasing proportions of aerosolvalves that are entirely of non-ferrous material are supplanting the formerly conventional aerosol-valves comprising a cap of ferrous material and a non-ferrous dip tube and finger valve. Hence, the use of the action of a magnetic field on the ferrous material cap during the orienting process, as has been taken advantage of in prior object-orienting machinery generally, is not now always available. Gther elongated tailed objects of, for example, plastic materials, such as integral dauber and stopper assemblies, dropper-cap units, and the like, present similar problems of orienting prior to insertion by appropriate machinery into the containers the objects are destined for.

With the foregoing in view, it is a primary object of the present invention to provide a simple, highly efficient and economic apparatus for automatically orienting a plurality of elongated tailed objects preparatory to use of such objects.

It is another object of the invention to provide apparatus of the character refer-red to above and which is of particular utility for orienting aerosol valves and similar objects preparatory to positioning such valves or objects in a series of structures such as aerosol cans or other containers.

it is another object of the invention to provide such apparatus which performs the desired orienting operation regardless of the nature of the materials from which the objects are made.

It is another object to provide apparatus of the charac ter referred to above wherein the objects may be dumped haphazardly into a hopper and are thereafter automatically properly oriented at the discharge end of the apparatus.

It is another object of the invention to provide such apparatus which positively assures orienting of the objects at the discharge end and ejects from the system for recycle therein unoriented objects prior to the arrival thereof at the discharge end of the apparatus.

Yet another object of the invention is to provide compact apparatus of the nature described which has the various com onents thereof coactively and spatially related to each other whereby the orienting function is positively assured and performed within a minimum space.

Another object is to provide means for continuously lifting objects from a hopper in which they are in haphazard relationship and feeding them substantially singly to an initially orienting movable surface.

It is yet another object to provide an initially orienting assembly that is capable of furnishing initially oriented elongated tailed objects at a rate upwards of objects per minute.

Another object is to provide such initially orienting assembly which comprises an upwardly moving surface and a slotted chute having its upper receiving end in objectreceiving relationship with the upper discharge end of said upwardly moving surface.

Another object is to provide metering means which assure discharge of oriented objects from the orienting assembly at predeterminable substantially constant intervals.

Another object is to provide an aligning assembly for positively assuring that any unoriented objects received thereby are forceably ejected from the assembly prior to delivery at the discharge end thereof.

Other objects and advantages of the invention will become apparent as a result of a better understanding thereof upon reference to the following description.

Generally, the invention resides in apparatus comprising a hopper adapted to contain the elongated tailed objects described which are to be oriented; a tail-aligning conveyor comprising a movable surface having an objectreceiving region and an objective-discharging end; a second conveyor operatively associated with the hopper and the tail-aligning conveyor and adapted to withdraw elongated tailed objects from the hopper and to deliver the objects seriatim to the object-receivins region of the movable surface; a tail-aligning chute having its object-receiving end positioned adjacent the object-discharging end of the movable surface and adapted to receive objects discharged from the end of the movable surface, the chute having discharge means at the lower end thereof adapted to discharge objeets therefrom; a horizontal aligning device having one end thereof located adjacent the discharge end of the chute in object-receiving relationship therewith, the horizontal aligning device having discharge means at its other end; an aligned-object accumulator, the accumulator being positioned in object-receiving association with the discharge means of the horizontal device; and diverting means operatively associated with the horizontal aligning device and comprising an object-engaging member and a chute having one end thereof in receiving communication with the horizontal aligning device and the other end thereof in discharge communication with the hopper, the object-engaging member being adapted to force unaligned objects from the horizontal aligning device into said one end of the chute. i v

In a preferred embodiment of a hopper conveyor assembly, particularly useful in the apparatus just described, the hopper, which is adapted to contain elongatedtailed objects, is provided with inclined wall means adapted to direct the objects in the hopper towards a predetermined bottom region thereof. The'conveyor is preferably an inclined elevating conveyor which has the bottom portion thereof in operative association with the predetermined bottoznregion of thehopper and comprises horizontally arranged flight bars adapted to fengage'beneath the en? largemen'ts-of the objects in said region? of the hopper and to convey them upwardly out of the hopper. A downwardly inclined plane is locatedbeneath the upper end of the elevating conveyor and is adapted to receive objects dropping from the upper end of the elevating conveyor. A horizontally disposed, rotatably mounted worm feed is preferably positioned adjacent the lower region of the inclined plane and is adapted to intercept the objects which move downwardly on the inclined plane. Driving means are provided for rotating the worm feed whereby objects intercepted thereby are caused to move horizon- 3 tally toward one end of the feed and finally to drop oif said end.

A preferred embodiment of the tail-aligning assembly referred to above comprises an orienting conveyor which has an upwardly-inclined, movable, upwardly-facing surface adapted to receive the tailed elongated objects to be oriented. Directing means are operatively associated with the surface of the conveyor and are adapted to direct the elongated objects carried upwardly by the surface to an upper predetermined region located on the longitudinai axis of movement of the surface. An orienting chute is provided which has a slot extending longitudinally along the bottom thereof. The chute has at least its upper end open and this upper open end is positioned adjacent to and facing the upper predetermined region of the movable surface with the slot of the chute remote from and in substantial alignment with said predetermined region. The tail-aligning chute extends downwardly from adjacent said region of the movable surface and is inclined in the same general direction as is said surface, whereby the chute is adapted to conduct objects discharged from predetermined region of the movable surface downwardly, with the tails of the objects in said slot.

In a preferred embodiment, the horizontal aligning means for the orienting apparatus comprises two opposed, substantially vertically disposed, substantially horizontally movable belts. Means are provided for supporting said belts in predetermined spaced relationship with each other with the lower edges of the belts closer together than are the upper edges thereof, whereby the belts are adapted to hold between them the enlarged ends of objects with the tails thereof depending through the space defined between the lower edges of the belts. A region of the opposed movable belts is provided where at least one of the belts is unsupported and means are provided for driving the belts in a common direction from. one end of the aligning means toward the other end. Feeding means are operatively associated with said one end of the aligning means and are adapted to discharge objects onto the belts. Compression means are located above the horizontal aligning means at least in the region of said unsupported section of said belt and are adapted to permit properly oriented objects to be conveyed between the belts toward the other end of the aligning means and to force unoriented objects downwardly out of the unsupported section.

The driving assembly comprises an electric motor 6 affixed to and suspended from

rails

14 and 17 by a pair of shallow U-shaped brackets 119. Electric motor 6 is supplied with a cable 121 for connection to a source of electric current and is provided with the usual on-otf switch and speed control (not shown). The drive shaft 171 of motor 6 extends to the right (as viewed in FIG. 2) beyond the vertical plane of

rails

8 and 9 and is provided near its end with a pulley 172 afiixed thereto for rotation therewith. The portion of shaft 171 extending to the left (FIG. 2) is provided short of its end with a pulley (not visible). A shallow U-shaped rail 123 is mounted by its ends on

rails

14 and 17. A pair of rods 124, attached to rail 123 and dependent therefrom, furnish bearings for the shaft 125 of a pulley 176 (FIG. 2). Attached to the extreme left end of shaft 125 is a bevel gear 127. A pair of bearing

rods

128 and 129 supported on and extending horizontally from standard 11 has rotatably' mounted therein shaft 146 which at its right end (as viewed in FIG. 1) has a bevel gear 141 meshing with bevel gear 127. The left end of shaft 149 has affixed thereto a pulley 142. Driving belt 143 is looped over

pulleys

142 and 52.

A pair of standards 144, each of which is respectively mounted on one of

rails

13 and 16, supports a drive shaft 145 which (as seen in FIG. 2) extends beyond the vertical plane of

standards

8 and 9. Fixedly mounted on said extension of shaft 145 for rotation therewith are

pulleys

146 and 147. A smaller pulley 148 is affixed to shaft 145 interiorly of the plane of

standards

8 and 9. A triple pulley 153 (only the proximate sheave of which is shown in FIG. 1) is mounted on said shaft 145 substantially midway of the portion of shaft 145 extending between standards 144. A driving belt 149 is looped over pulley 172 of electric motor 6 and over pulley 146 on shaft 145. Endless belt 159 drivingly connects pulleys 147 and while endless belt 151 drivingly connects

pulleys

148 and 164. As best seen in FIG. 1, a driving belt 152 is looped over the proximate sheave of triple pulley 153 on horizontal shaft and after a half twist is looped around front pulley 95 atlixed to the upper end of vertical shaft 91. Similarly, a second half-twisted endless belt 154 is looped over the remote sheave of triple pulley 153 and rear pulley 95 (FIG. 2). The middle sheave of triple pulley 153 is drivingly connected with pulley 135 by an endless belt 155. Endless belt 156 drivingly connects pulley 51 with pulley 126. Another endless belt 156 drivingly connects the pulley (not visible) on the extension of shaft 171 to the left, as viewed in FIG. 2, to pulley 126.

The operation of the above apparatus will now be described with respect to its use for orienting aerosol dip tubes as an example of the elongated tailed objects for which said apparatus is particularly adapted. As shown in FIG. 10, these dip tubes 159 conventionally comprise a valve head 169, which may be of metal or plastic material, an elongated tube or stem 161, and a shorter tube 162 which functions as valve actuator and discharge conduit when the dip tube is positioned in an aerosol container.

A plurality of dip tubes 159 are dumped into hopper 30 in haphazard relationship. Motor 6 is started and through the driving

system comprising belts

156 and 143 and the associated

pulleys including pulleys

126, 142 and 52 described hereinbefore, elevating conveyor belt 40 moves in the direction of the arrow (FIG. 2). As cleats 53 on belt 40 move upwardly through the mass of dip tubes in hopper 30 (which dip tubes are directed against elevating conveyor belt 40 by inclined wall 37), the valve heads 160 of various dip tubes 159 are engaged by said cleats and lifted upwardly with the stems 161 of the valves depending as shown in FIG. 2 at 11. Other dip tubes may be picked up in lateral position on cleats 53 as shown at b. When the dip tubes 159 reach the upper discharge end of endless belt 40 they slide downwardly on inclined plane 54 until they reach the substantially V-shaped area defined between the bottom region of inclined plane 54 and the adjacent periphery of worm feed 121. As worm feed 121 rotates in the direction of the curved arrow (FIG. 3), helical cleat 125 engages the valve heads 160 and/or the ends of stems 161 of the dip tubes 159 and moves the latter towards the left end of worm feed 121 as viewed in FIGS. 1 and 3 until they drop off said end into the receptacle 66 formed by

walls

67 and 70 on the upper surface of upwardly moving endless belt57. As will be apparent upon inspection of FIG. 3, if perchance a dip tube 159 on worm feed 121 falls from the periphery thereof remote from plane 54; due to the relationship of parts, the dip tube will still drop to the upwardly moving surface of endless belt 57. As the dip tubes 159 move upwardly they are caused by diverters 72 to be directed to a limited location at the upper end of endless belt which is in substantial alignment with the inverted funnel-shaped mouth of the upper curved portion of chute 4 defined by walls 77.

Because the valve heads 160 of dip tubes 159 have a greater mass than do the tails 161 thereof, the frictional efiect of the upwardly moving surface 66 of belt 57 (which in this case was of rubberized canvas, inclined at an angle of approximately 30 and driven at a linear speed of approximately 5 feet per second) is to cause most of the dip tubes 159 to orient as they move upwardly to assume the position where the heavier valve end 160 is leading (as shown at 159a in FIGS. 2 and 3), since the 9 tail 161, being lighter tends to slip rearwardly as the belt moves forwardly and upwardly.

Hence, in the more usual or normal situation, the dip tubes 159 are caused to orient themselves on endless belt 57 to the extent that the heavier valve ends 160 lead the lighter tail ends as they move upwardly on said endless belt. When the tubes reach the upper end of the belt 57 and begin to fall off the belt as they move outwardly due to the momentum imparted them, the valved ends 1641 coming oif endless belt 57 first begin to drop to assume position 1591) in FIG. 5. Then as the tubes move outwardly and downwardly, the leading periphery of the valve head 160 engages and is checked by the narrowing area defined by walls 77 of chute 4 with the result that the tail portion 161 continues to move forwardly and is directed by the converging sides of the walls 77 so that tail 161 then extends through slot 78 as illustrated at 15% (FIG. 5). Gravity then predominates so that the dip tubes are then oriented to position where the lower surface of the valve heads engage the converging surface of walls 77 and the tail protrudes through slot 78 as the tubes continue their descent in chute 4 in oriented relationship as at 159d and 159:2.

In the rare case where the tail is leading as at 159 (FIG. 2), as the dip tube 159 reaches the upper region of endless belt 57 Where it turns downwardly over upper roller 58, gravity causes the tail 161 of dip tube 159 to begin to tilt downwardly while the momentum of the entire dip tube 159 causes it to move forwardly into the open mouth of chute 4. The funnel-shaped cross-sectional configuration of the walls 77 towards slot 78 directs the tail 161 into said slot in all these cases. Hence, the dip tube 159 enters upper region of chute 4 in the position shown in FIG. 1 in dotted lines and designated 159g. The dip tube 159 continues to move forwardly due to its momentum and downwardly due to gravity until it is positioned in the chute with the under surface of valve head 16% abutting the interiorly lower surface of chute 4 and with the tail 161 protruding through the slot 78 as shown in dotted outline designated 15911.

As the upper valve stems 162 of dip tubes 159 move down in chute 4 as at 1591' (FIG. 1), and are contacted by metering wheel 132, due to the high peripheral speed of said wheel 132, the tubes are caused to be accelerated downwardly one by one to the discharge end 136 of chute 4. After they fall from the discharge end 136 of chute 4, the dip tubes 159 alight in the V-shaped area between

endless belts

93 and 94 which are moving in the direction of the arrows. If the dip tube is properly oriented at this time it rides through the V-shaped area with the lower surface of valve head 169 resting at two opposite points on its periphery between the opposed surfaces of

endless belts

93 and 94. The tail 161 of the dip tube extends downwardly between the opening or slot provided at the bottom of the V-shaped area, and the upper stem 162 rides within the slot 112 of U-shaped member 119 (FIG. 7). The dip tubes are moved by

endless belts

93 and 94 to the left as viewed in FIG. 1 until said tubes approach beyond left bearing surface 193 Where the convergence of the bottom edges of

belts

93 and 94 begins to diminish. At this point the oriented dip tubes 159, no longer retained by the bottom edges of

belts

93 and 94, move downwardly and forwardly until they alight upon accumulator chute 166 with the tails of the dip tubes 159 extending downwardly through slot 197. The dip tubes 159 are then urged along on accumulator chute 106 by the metering wheel 1&5 toward automatic machinery for inserting dip tubes into aerosol containers therefor, for example (not shown).

In the event a dip tube 159 is not properly oriented when carried between

endless belts

93 and 94 beneath U-shaped member 110, bottom reach 111 thereof then functions as a pressure bar to push the unoriented dip converging bottom edges of

endless belts

93 and 94 in the region of U-shaped member are unsupported, the dip tubes move downwardly as they urge the resilient edges of the belts outwardly until the tubes fall free of the belts and into the open mouth 115. The dip tubes then slide downwardly via

conduits

116 and 117 until they enter hopper 30 through aperture 118 for recycling through the orienting apparatus. As will be understood, the dip tubes 159 may be improperly oriented in various ways such as by being inadvertently disposed longitudinally of the V- shaped area between belt surfaces 105, as illustrated in dotted outline in FIG. 8; or by being vertically disposed, but bunched together so that the valve 160 of one dip tube 159 rides atop the valve 160 of an adjacent dip tube 159, whereupon reach 111 of pressure bar 110 will perform its function of forcing such unoriented dip tubes downwardly between the unsupported convergent sections of the

belts

93 and 94 and into return hopper 113.

It will be understood that the above-described embodiment of the invention is merely illustrative thereof. Thus, numerous other arrangements and modifications of the components of the apparatus may be readily devised by those skilled in the art which will embody the principles of the invention and fall within the spirit and scope thereof. Merely by way of example, chain and sprocket drives may be substituted for the belt and pulley drives shown, more than a single motor or other prime mover means may be utilized as driving means, other diverting means may be provided for the inclined endless orienting belt than those shown, the inclination, material and speed of said inclined endless belts may be varied, the metering wheels may be substituted by endless belts, etc.
