Definitions

  • the invention particularly relates to container filling machines of the type useful in the environment designated in U.S. patent 3,800,400 and more particularly relates to improvements in machines of the type disclosed in U.S. patent 3,601,288. While not limited to the dispensing of charges of material into plastic containers, the machine is particularly useful in dispensing a predetermined quantity of fluid, or semi-fluid product from a supply which is contained in a tank or the like, and typical products may include yogurt and milk.
  • One of the prime objects of the present invention is to design an extremely sanitary machine which dispenses only metered volumes of material to the containers, and is capable of readily dispensing different metered charges to containers of different size, with only a simple and convenient pump stroke varying mechanism.
  • Still another object of the invention is to provide a filling machine of the character described which positively prevents the dispensing of product to a container pedestal to which no container has, in fact, been delivered in a most reliable and economical manner.
  • Still another object of the invention is to provide a construction which can be readily cleaned, and readily reassembled.
  • a sanitary filling machine with a carrier for individual containers and surrounding a central supply tank is rotated with the tank and rotary valves are provided which in one position feed material from tank outlet passages to a plurality of positive displacement pistons, and in another position permit the pumping of material by the pistons through dispensing openings to the containers, a cam track for determining the lower position of each pump piston in the suction stroke is swingable to various adjusted positions to meter material to the container according to the volume of the containers being filled.
  • the mechanism is constructed to facilitate cleaning.
  • the machine is shown as having a frame F supporting an upstanding sleeve 10 which has a flange 10a bolted to the frame at 11.
  • Bearings 12 and 13 mounted by sleeve 10 journal a central shaft 14 which is adapted to be driven by a spur gear 15 connected with any suitable source of rotary power.
  • a tank mounting orbiting assembly supports a liquid-filled tank 16 for rotation with the shaft 14. Also mounted for rotation with the assembly are a plurality of pump housing assemblies A, pins 17 being provided to secure the housings A in place surrounding the outlet portion 16a of tank 16 as shown. It is to be understood that the outlet portion 16a has an outlet passage 18 and that the number of assemblies A depend on how many containers are to be supported on the machine and filled during the revolution of shaft 14.
  • the passages 18 are in radial alignment with passages 18a provided in the pump housing assemblies A, which, as Figure 2 indicates, are sandwiched between the tank outlet portion 16a and a plurality of valve mounting and material dispensing housing assemblies 19 which are mounted outboard radially of each pump housing assembly A.
  • seal rings 20 are provided around outlet portion 18 in slots 21 provided in each housing A to seal passages 18 and 18a at the juncture of housings A and 16a, and circular seal rings 22 are provided in slots 23 in the housing assemblies 19 to seal the passages 18a and passages 19a provided in the assemblies 19 at the juncture of the housings 19 and A.
  • Each pump assembly housing A includes a dependent cylinder 24 within which a piston pump 25 (which is designated 25a) being slotted to receive a sealing O-ring 26 as shown.
  • Each assembly 19 is provided with a frustoconically shaped recess R communicating with an associated passage 19a to receive a rotary frustoconical valve 27 which later will be more particularly described, and it will be seen that a pump cylinder 24 is positioned opposite each recess R and valve 27..
  • Springs 27b retained by removable retainers 27a secured in the outer ends of the recesses R urge valves 27 inwardly and a sealing ring 27d is provided as shown.
  • Openings 29 are provided in the radial outer wall of each pump cylinder 24, so that when a valve 27, with its port system 30, is in the position shown in Figure 2, it communicates the passage 19a with the filling passage 31 above piston 25a via a port 29.
  • Each port system 30 includes ports 30a and 30b, and a port 30e perpendicular to port 30b, and in the Figure 2 position, ports 30a and 30b communicate passage 19a with pump housing 24.
  • Each pump assembly housing A carries a container supporting pedestal 32 having a partly enclosing side wall 32a for supporting an open-topped yogurt container y which is in position to be filled through a dispensing opening 33 provided above each pedestal 32 in communication with each valve recess R.
  • valve 27 when the valve 27 is rotated approximately 90° from the suction position in which it is shown in Figure 2, port 30e of angle shaped passage system 30 will communicate with the dispensing opening 33 and deliver material ejected by the pump piston 25a through port 29 and the portion 30b of passage system 30 to dispensing opening 33 via port 30e.
  • valve housings 19 Mounted below valve housings 19 are a pair of semi-circular,detachable, orbiting, condensate collecting and spill trays 34, each having passages 34a beneath each opening 33 formed by riser walls 35 which are of greater height than the tray outer lips 36.
  • each pump plunger 25 includes an upper stem part 25b and a lower stem part 25c, joined by a coupling 37.
  • the rotatable tank-supporting annulus frame or cage C which is journaled by a bearing 39, includes a top plate 41 to which an under plate 42 is bolted as at 43. Under plate 42 is bolted to the annular cage C as at 44. Depending from plate 42 is the flange 40 which is welded to shaft 14 and may be bolted to plate 42 as at 45.
  • a pin 46 centrally disposed in openings 47, 48 and 49 in members 42, 41, and a bottom plate 16b for tank 16, respectively, is provided as shown to aid in locating the parts for assembly.
  • a guide ring 50 bolted to the cage C intermediate its length as at 51, mounts slide bearings 52 for the pump piston lower parts 25c, and a further guide ring 53 with slide bushings 54 for the piston stem parts 25c is also provided.
  • Figure 1 shows a pump piston 25 in both an upper and lower position.
  • a follower roller 55 received within a recessed guideway 56 formed in cage C.
  • Each roller 55 is mounted on a threaded stem 55a received in a threaded opening 57 provided in a block 58 fixed to the lower stem part 25c of each piston 25.
  • each piston 25 at any time is determined by the vertical position of a cam follower roller 59 which is mounted in a block 60 dependent from each block 58.
  • the vertical position of each roller 59 is influenced by either an upper arcuate cam part 61 or a lower annular cam part 62, dependent on its orbital position.
  • the lower cam part 62 is fixedly secured to an angle plate 64 which is fixedly secured to frame F.
  • the upper cam part 61 is pivotally secured as at 65 to a brace 66 projecting inwardly from frame F and mounted for vertical swinging movement upwardly and downwardly relative to fixed cam part 62 to vary the lower limit position of each plunger 25 and determine the volume of liquid dispensed according to the size of the container being filled.
  • a gear 71 on the lower end of screw 69 is in mesh with a worm gear 72 fixed on an adjusting shaft 73 which is fixed against axial movement journaled by frame F.
  • a hand wheel 74 may be provided on shaft 73 to permit its manual rotation or, if desired, the shaft 73 could be motor driven.
  • the lowermost positions of cam 61 and roller 59 are indicated at 61' and 59' respectively in Figure 8.
  • Figure 3 schematically depicts the positions of the cam parts 61-62 and the valve 27 control or actuation abutments 75 and 76. These abutments are provided in the rotary path of the levers or handles 77 which are pinned as at 77a to the stem portion 27a of each valve 27, handles 77 having stems 77b received in bores 27e provided in the outer end of each valve 27.
  • the abutment 75 is fixed in position and arranged to rotate the valves 27 approximately 90 degrees when the ends of the handles 77 strike them, to a suction position in which the port systems 30 is in communication with passages 19a and out of communication with openings 33. This occurs after the charge of material has been delivered to the container at a time when the pump pistons 25 are in "up" position.
  • Abutment 76 normally reverses each valve 27 because it is at a different level in position to engage the opposite upper end of each handle 77 and cause it to swing in the opposite direction. It is to be observed however, that the abutment 76 is retractable from normal position to a position in which it is radially out of the path of the handles 77 and will not activate them to move the valve bodies 27 to a dispensing position. For this reason, abutment 76 is mounted on a bar 78 ( Figure 4) having stems 78a received in bushings 79 provided in a solenoid casing 80. The stems 78a are in surrounding relation with a solenoid core 81 and spring 82 is provided to normally force bar 78 to outer normal position.
  • FIGS. 5 through 7 particularly indicate the manner in which the assemblies 19 and A are supported by the tank housing 16b in the manner which permits them to be easily dis-assembled. It will be observed that the outer perimeter of part 16b is a fourteen-sided polygon and it will further be observed that threaded openings 83 are provided in the tank part 16b at the junctures of the mounting walls of the portions 16b to accommodate mounting stud members 84.
  • the housings A in front elevation are substantially T-shaped and include converging sockets 85 from which the assemblies A are suspended on studs 84.
  • the assemblies 19, which also are generally T-shaped in front elevation have converging sockets 86 to similarly suspend the assemblies 19 on the studs 84.
  • Clamp washers 87 provided on the studs 84 may be secured by nuts 88 within recesses formed by shouldering the assemblies 19 as at 19c, and as will be seen have wedge walls 87a which engage with similarly inclined walls 89 on the assembly portions 19 to clamp the housings 19, and thereby the housings A, securely in position.
  • each plug 90 includes a shoulder portion 90a snugly fitting into opening 91 and has an 0-ring or other suitable seal 92, as shown.
  • outboard walls 93 thereon have bayonet slots 94 for receiving pins 95 provided on the assemblies 19 and the plugs 90 are twisted to engage the pins 95 in the slots as the plugs 90 are moved >to position.
  • a passage 96 Leading upwardly from each assembly 19 from plug receiving chamber 91, is a passage 96 leading to a tube 97. Tube 97, as indicated in Figure 1 leads back into tank 16.
  • each of the recesses 91 in each housing 19 is fitted with a plug 90 and water introduced through the tube 98 into the interior of tank 16 is then re-circulated through the assemblies A and 19 back to the tank 16 via ports 96 and hoses 97.
  • Only one hose 97 has been shown in Figure 1 but it is to be understood that each of the housings 19 may have a hose 97 or that a manifold (not shown) can be provided to which ports 96 lead and that a single hose may then lead from it back into tank 16.
  • a water flush has been accomplished, one of the parts 27 can be removed to drain the water from the system. Thereafter the process can be repeated with a sanitized cleaning solution, and suitable water and cleaning solution flushes can be alternated until the desired sanitary cleaning has been accomplished.
  • a star wheel 99 is provided to deliver containers to each pedestal 32 as the pedestals move past the pockets 99a in the star wheel.
  • abutment 75 has been engaged by the handle 77 of the particular assembly 19 to rotate the particular valve 27 through substantially 90° to the "fill" position.
  • the piston 25 is in its lowermost position, riding on the lower fixed cam 62.
  • fixed cam 62 see Figure 8 moves the piston 25 upwardly to dispense fluid to the container and by the time fixed abutment 75 is reached, the dispensing operation has been completed.
  • valve 27 When the opposite end of handle 77 contacts abutment 75, the valve 27 is reversed to bring the valve 27 to the Figure 2 position, and the suction stroke of the pump piston 25 can begin. By the time a container reaches the star wheel 100 and is removed by it, valve 27 has completely closed and the position of star wheel 100 is such that its pockets 100a engage and remove the container from each pedestal 32 at a point slightly downstream from the fixed abutment 75.
  • cam 61 which moves the piston 25 downwardly in the suction stroke indicated in Figure 3.
  • the pivotal position of cam 61 determines the length of the suction stroke within certain predetermined limits to handle the volume requirements of various containers.
  • the two extreme bottom positions of the follower rollers 59 are shown at 59 and 59' respectively.
  • the roller 59 When the roller 59 is in the position indicated in solid lines in Figure 8, it can move across to the cam surface of cam 62 in the path x and bypasses part of the cam surface 62.
