- the process and apparatus of the present invention have particular utility in the packaging of a semi-fluid dairy product; such as, for example, yogurt, cottage cheese and sour cream, although it will be appreciated from the ensuing detailed description that the process and apparatus of the present invention have general utility in the packaging of other fluid and semi-fluid food products.
- Semi-fluid food products such as those mentioned above are conventionally packaged in wax coated paper or plastic containers of various sizes. Such containers are usually generally frusto-conically shaped, and are transported to a dairy in a carton containing a plurality of stacks of containers nested within one another.
- a still further problem that is prevalent in the semifluid food packaging art is the difficulty of providing a product filling mechanism that will accurately meter a selected quantity of product into the container without splashing and spillage of the product, and without dripping when containers are being moved into and out of product filling relationship with respect to the filling means.
- the problem of drippage from the container filling means is very severe in the packaging of a semifiuid dairy product of the type mentioned above.
- the present invention provides a novel container dispensing mechanism and product pumping mechanism which cooperate to produce a high speed multiple line packaging arrangement for semi-fluid food products.
- the container dispensing assembly guarantees continuous operation of the machine, by providing an arrangement where the lowermost containers are simultaneously stripped from a plurality of stacks of nested containers in a magazine assembly.
- the stripping action is provided by positioning a blocking plate above the lowermost container in each stack of containers during a container dispensing step, and lifting the remaining containers in the stacks to positively dislodge the lowermost container therefrom.
- the lowermost container of each stack is supported upon a platform member, and vacuum is applied to the lowermost container to positively retain the same on the platform means.
- the platform means is subsequently lowered to positively transport and accurately position the lowermost containers on a conveyor, which moves the containers to a filling station.
- each product dispensing nozzle is a positive displacement piston pump that is controlled by a spool valve.
- the spool valves insure that a precise volume of product will be pumped into each container, and the spool valves are arranged to create a suction on the nozzles after the containers have been filled, to prevent drippage from the nozzles when a further group of containers are moved into position at the filling station.

- a pin 380 extends rearwardly (as viewed in FIG. 14) from block 354 and fits within a slide block 382 that is positioned within a horizontal slot in a motion transmitting arm 384.
- Vertical guide rods 386 are fixed to the machine frame, and guide blocks 388 on member 384 slide along rods 386 to confine arm 384 for vertical movement. It will be appreciated that the maximum arc of block 354, and therefore the maximum vertical movement of arm 384, will take place when the block 354 is spaced the maximum distance from pivot 360, as shown in FIG. 14.
- motor 340 is energized to move block 354 to the left, as viewed in FIG. 14, the
- Links 390 are connected at the outer ends of member 384, and are pivotally connected tothe upper end of links 310.
- the adjusting motor 340 is energized to position the block 354 at an appropriate position on shaft 352 to locate pin 380 relative to the slot in member 384 in a position that will provide the appropriate volume of product for the particular size containers 58 carried by the conveyor 22.
- arms 316 are pivoted in a clockwise direction, as viewed in FIG. 2A, to move the pistons 230 to the right, as viewed in FIG. 12, as spools 246 are moved downwardly by cams 280 to move O-rings 254 into sealing relationship within chambers 26 and to move reduced diameter portions 256 into chamber portions 224.
- Valve spool portions 248 act as plungers to force the product within chamber portions 242, sleeves 244 and the portion of passage 210 therebelow into the respective cylinders 228. During the latter portion of the downward movement of spool 256, the product within chamber portions 226 is forced outwardly through noz-' zles 234 into the containers 58 that have previously been partially filled by the leftward movement of pistons 230. As was previously mentioned, during the entire product discharge portion of the filling cycle, the containers 58 are retained in an elevated position by platform 288. After the appropriate amount of product has been discharged into each container, cam portion 278a moves into engagement with follower 276 and spool 246 is moved slightly upwardly to the broken line position of FIG. 12. This applies a suction to the nozzles 234 while the containers 58 are being lowered by the platform 288 and while subsequent containers are moved to the filling station, thereby preventing product from dripping from the nozzles 234.
- cam 280 begins to move spools 246 upwardly, while platform 288 elevates the empty containers 58.
- arms 316 are pivoted in a counterclockwise direction as viewed in FIG. 2A, to move cylinders 230 to the left as viewed in FIGS. 11 and 12 to pump the product contained within cylinders 228 outwardly therefrom, and outwardly of the chambers 220 through nozzles 234.
- the rows of filled containers are brought to the lidding station 42, where a closure is applied to each container by a shuttle feeding mechanism, not shown.
- a coding mechanism also not shown, may be provided between the lidding station 42 and the take away station 44, if desired, for the application of date, price, product identification and other information to the containers.
- the filled containers are transferred to a discharge conveyor, not shown, for subsequent packaging and easing.
