(Cl. 141-140) This invention relates to machines for filling containers with liquid materials and is more particularly concerned with improvements in an automatic filling machine of the rotary mul-ti-station type for sequentially filling containers with a measured volume of liquid as the containers successively pass through the machine.
It is a general object of the invention to provide a rotary multi-station container filling machine which operates automatically upon delivery of a succession of containers thereto to deliver a pre-measured volume of liquid into each successive container as the containers move in a circular path beneath a plurality of peripherally spaced, valve controlled measuring heads which are operated by elevating the containers into engagement with the heads.
It is a more particular object of the invention to provide a rotary multi-station filling machine for dispensing into successive containers .a pre-measured volume of liquid wherein a plurality of measuring cups are mounted for vertical reciprocation in apertures in the bottom of a circular bowl or tank which is filled with a liquid to a predetermined level, the cups being open at the top and being reciprocated, by engagement with the containers, be-
tween a cup filling position where the open top is below the level of the liquid in the bowl and a discharge position where the top of the cup is above the liquid level in the bowl and each cup having a discharge valve in the bottom thereof which is operated to drain'the contents of the cup into the container which is in engagement therewith.
It is another object of the invention to provide a multistation rotary type filling machine for dispensing liquid into a series of successive containers which are moved into position beneath a plurality of measuringcups which are mounted in a rotating supply tank in which the liquid is maintained at a constant predetermined level and the cups are reciprocated between an immersed position below the level of the liquid in the tank and a container filling position where the opentop of the cup is above the level of the liquid inthe tank, with each cup having is opened, so as to drain the contents of the cup into a container, by a segmental circular ca-rn at the top of the tank which is engaged by a cam follower on a valve lifting stem.
1 It is a further object of the invention toprovide an automatic liquid filling apparatus comprising a rotatably mounted, upwardly opening, cylindrical tank having vertically disposed spaced Walls extending about the periphery with the'inner wall being of lesserheight than the outer Wall sothat a supply of liquid may be maintained at a constant level in the tank with excess liquid spilling over the inner wall into a collecting receptacle, the tank having a plurality of measuring cups mounted in spaced apertures in the bottom wall thereof which are each vertically reciprocable between a cup filling position where the top of the cup is below the level of the liquid in the tank and a container filling position where the cup is elevated to bring the top above the level of the liquid in the "tank by engagingthe open top of a container to be filled with the lower end of the cup and raising the container to a predetermined position, each cup having a valve opening in the bottom thereof and a ball valve which is supported on a vertically disposed stem which stem has a cam follower on its upper end for engagement with a fixed opmembers 15 are mounted.

These and other objects and advantages of the invention will be apparent from a consideration of the machine which is shown by way of illustration in the accompanying drawings wherein:
FIGUREI is a plan view of the filling machine which incorporates the principles of the invention, with portions of the machine being broken away;
FIGURE 2 isa partial vertical section taken on the line 2-2 of FIGURE 1, to a larger scale;
FIGURE 3 is a partial vertical section taken on the line 22 of FIGURE 1, to a still larger scale; and
FIGURE 4 is a fragmentary side elevational view taken on the line 4-4 of FIGURE 1.
Referring to the drawings, there is illustrated a liquid dispensing machine which is particularlyadapted for use in connection with the filling of liquid products into The apparatus is, however, not limited to the filling of any particular type of container or to the dispensing of any particular liquid material.
The apparatus comprises a hollow base assembly 10 (FIGURES 1 and 2) of generally cylindrical shape having a vertically disposed central hub 11 on which there is rotatably mounted, by means of vertically spaced bearings :12 and 12, a ring-like platform support 13. The platform support 13 has 'an upwardly facing, horizontally disposed annular surface 14 on which a'plurality of circumferentially spaced container receiving platform support support ring 13 also carries a bowl-like liquid supply tank or reservoir 16 and associated valve assemblies 17 disposed above the platform support members 15. The platform support ring 13 is provided with a ring gear 18 which is driven by a pinion vertical drive shaft 20. The drive shaft 20 is mounted in the bearing formation 21 in the base assembly 10 and at its lower end has a shear pin connection 22 with a motor 23 mounted on a bracket 24 within the base 10. This provides a direct drive forrotating the turret-like support member 13.
The base assembly 10 supports at one side of the machine an infeed and outfeed conveyor assembly 25 (FIGURE 1) for delivering the empty containers C to the platform support members 15 at the entry side of the for removing them at the discharge side of the turretafter they traverse the circular path of the turret and receive a charge of liquid. The
The platform members or assemblies 15 each comp-rise a horizontally disposed container supporting plate 54 having a depending stem 55 which is slidably mounted in one of a plurality of vertically disposed bearing forming bores 56 spaced about the outer margin of the turret member 13. The stems 55 each carry a cam follower roller 57 on the lower end thereof which cam follower 57 is adapted to ride on the track formed by the top edge of a cylindrical platform cam 58. The cam 58 is mounted in fixed position on the edge of the top face 59 of the base assembly 10. A guide rod 60 depends from an inner end of each of the plates 54 and is received in sliding relation in a vertically disposed guide forming bore 61 in the turret member 13.
The bowl or tank forming assembly 16 has a circular aperture 64 in the center and an outer liquid receiving annular trough 65 extending about the peripheral margin which opens upwardly. The bowl assembly 16 is connected to the turret forming support member 13 by a series of depending pins 66 which are received in sliding relation in hollow vertical posts 67, the latter projecting upwardly of the surface 14 of the turret member 13. The bowl or tank assembly 16 has an outer wall 68 which rises a predetermined distance above the top edge 70 of an inner wall 71. An inwardly extending, downwardly inclined rim section 72 extends from the inner wall edge 70 to the center opening 64 so that when liquid in the trough 65 rises above the edge 70 of the inner wall 71 it will spill over the edge 70 and down the inclined rim surface 72 for discharge through the opening 64 into the top of a funnel-like collecting member 73 which is supported on the top edge of a vertically disposed tubular post 74. The post 74 extends upwardly from the base 13 with its upper end received in the hub 11 and with its lower end closed by a plate 75 having secured on its inner face an upstanding nut-like member 76 in which a supporting rod 77 is threadedly received. The rod 77 is adapted to be rotated to raise and lower the post 74 so as to adjust the upper edge of the funnel member 73 relative to the lower edge of the flange 72 of the bowl assembly 16. The support rod '77 is supported at its lower end in a bearing box 78 and has a gear connection with a linkage 79 extending to the wall of the base assembly 10 and receiving a handle 80 for manually rotating the same so as to turn the support rod 77 and raise and lower the post 74. The funnel member 73 has a discharge opening 81 at the bottom end thereof to which a discharge hose '82 is connected for draining off the liquid which spills over into the funnel member 73 and returning it to the liquid supply. A top cover member 83 is provided for the assembly 16 which has a depending hub-like sleeve forming section 84 at the center for mounting the same on the upper post forming portion 85 of a supporting bracket 86. The bracket 86 has a plurality of outwardly and downwardly inclined legs 87 with the lower ends thereof seated on a shelf forming flange 88 defining a cylindrical section 89 at the lower center of the funnel member 73. The cover member 83 has a series of removable sections 90 providing ready access to the inside of the bowl assembly 16. The post forming portion 85 of the bracket 86 is hollow and accommodates a conduit 91 through which fluid is delivered to the trough 65 in the bowl assembly 16.
The bowl assembly 16 is provided around its periphery with a series of measuring cup and valve assemblies 17 each of which comprises a cylindrical cup member 92 having an open upper end and a plug-like member 93 in the lower end. The plug forming member 93 constitutes a part of a cap assembly 95 which is provided with a pair of oppositely disposed, radially extending protuberances 96 each having a vertical bore 97 for receiving a guide forming pin 98. The guide pins 98 depend from the bottom wall 100 of the assembly *16. The cup 92 is mounted for vertical movement within a sleeve 101 which is fixed in an aperture 102 in the bottom wall 100. A bellows forming member 103 has its lower edge clamped in the aperture 102 by the sleeve 101. The upper edge of the bellows 103 is secured about the top margin of the cup 92. The bellows member 103 may lbfi formed of any suitable material which is resistant to the liquids with which the apparatus is employed and which is adapted to form an impervious, expansible shield between the top edge of the cup 92 and the bottom wall of the trough so that the cup 92 may be raised and lowered without liquid escaping through the aperture 102. The plug member 93 at the lower end of the cup 92 is provided with an axially extending discharge opening 104 terminating at a valve seat formation 105 for a ball valve 106 which is mounted on the bottom end of a vertically disposed rod 107. The rod 107 extends upwardly through an aperture 108 provided in the top wall forming member 83 and carries on its upper end a block M0 on which a cam follower roller 111 is mounted. The block is provided with an aperture 112 for receiving a vertically disposed guide rod 113 which extends upwardly of the top surface of the cover member 83 and which carries a compression spring 114 for limiting the upward movement of the block 1 10. The cam follower roller 111 is adapted to ride on the track forming top edge 115 of a cylindrical plate cam 115 which is mounted on the upper end of the bracket 86. When the cam roller 111 is engaged with the cam plate 115 the ball valve member 106 is raised so as to open the discharge passageway 104 at the bottom of the measuring cup 92. When the cup assembly is not raised the cam roller 111 passes beneath the cam plate i115 and there is no valve operation so that the contents of the cup is not discharged. The valve rod 107 is provided with a sleeve member 116 which encompasses an upper portion of the rod 107 and has a threaded connection with the same so that rotation of the sleeve 116 moves the same axially on the rod 107 or raises and lowers the same thereon. The sleeve 116 functions as a fine adjustment for varying the volume of liquid which is tredeived in the cup 92 when it is lowered to bring the upper edge below the level of the liquid in the trough 65. Preferably, removable inserts 117 are provided for the cup 92 so as to permit the volume of the cup to be adjusted by insertion or removal of the inserts 117, the latter, of course, being cylindrical in shape and permitting discharge of the liquid through the axial passageway 1-18 therein when the rod 107 is raised to open the valve 104.
The cam track forming plate member 115 at the top of the machine extends circumferentially of the turret from a point just beyond the entry point of the containers from the star wheel 27 to a point short of where the containers are removed by the star wheel 31. The upper edge 1.15 of the cam plate 115 is at a level'sufficient to raise the valve lball 106 for opening the valve after the valve assembly has been elevated by upward movement of the platform member 15 and engagement of the mouth of the container C with the plug member 93 or cap 95, so as to empty the contents of the cup 92 into the container C while all the elements are in the raised position.
In using the apparatus, liquid is supplied to the trough 65 through the conduit 91 so as to fill it level with the upper edge 70 of the inner wall 71 and to maintain it in form members 15 are raised and the container C beneath the same.
