assiguors to Bartelt Engineering Company, 1112., Rockford, 113., a corporation of Delaware Filed July 16, 1962, Ser. No. 218,699 7 Claims. (Cl. 137-440) This invention relates to valves adapted for use in automatic packaging machines to fill successive containers advanced step by step by a conveyor which carries each container into a position under the valve to be filled when the valve is opened. More particularly, the invention relates to a valve for dispensing measured amounts of at least partially liquid material.
The object of the present invention is to provide novel and relatively simple means for preventing delayed dripping of liquid from a valve of the above character after the valve is closed and during indexing of the conveyor thereby to avoid spattering of the packages, the packing machine, and the adjacent work area.
Other objects and advantages of the invention will become apparent from the following detailed description taken in connection with the accompanying drawing, in which,
FIGURE 1 is a fragmentary side elevation of a portion of a packaging machine embodying the novel features of the present invention with parts broken away and shown in section.
FIG. 2 is a fragmentary sectional view taken along the line 2-2 of FIG. 1 with the parts in different positions.
As shown in the drawings for purposes of illustration, the invention is embodied in a valve 10 constituting part of an automatic packaging machine (not shown) and operable to dispense measured amounts of at least partially liquid material such as strawberries and their juice to be packaged in bags 11 and frozen. The material is stored in a suitable hopper or tank (not shown) and delivered to the valve through a tube 12 leading into the upper end of the valve body or housing 13, the valve being alternately opened and closed to permit a timed flow of material through an orifice forming a discharge port 14 in the underside of the housing. The bags 11 are advanced step by step in timed relation with the operation of the valve by a conveyor (not shown) which carries successive bags through a filling station in which the open upper ends of the bags are disposed below the discharge port to receive the charges of material.
In this instance, the product is guided into the bags through a spout 15 comprising two so-called clam-shell buckets 17 of channel-shaped cross-section opening toward each other and secured adjacent their upper ends to parallel rock-shafts 18 journaled in a block 19 sup- I ported above the conveyor on a slide 20. The latter is slidable vertically on rods 21 to raise and lower the spout between an upper position in which the spout is above the level of the bags on the conveyor and a lowered position in which the tips of the buckets are inserted in the open end of a bag as shown in FIG. 1. When the spout is in the lowered position and the buckets are spread apart to guide the material into the bag, the tips hold the bag open and protect the seal aeras 22 of the bag against contamination resulting from splattering of the product during filling.
After one bag is filled, the buckets are closed in a manner well known to those skilled in the art and are raised out of the bag for movement of the next bag into a position to be filled. For faster filling, banks of spouts and valves may be used so that a plurality of bags are filled after each indexing of the conveyor. In some applications, the material may be released directly into the packages from the discharge port of the valve without passing through a spout.
The valve 10 herein includes a cylindrical barrel or plug 23 journaled in the housing 13 for back and forth oscillation and formed with a passage 24 extending through the plug and opening radially outwardly through inlet and outlet ports 25 and 27 angularly spaced around the plug. The lower wall 28 of the housing is curved to fit closely against the underside of the plug. In one angular position of the plug, the outlet port 27 is alined with the discharge port 14 and the inlet port 25 is alined with a feeding port comprising the lower end 29 of a passage 30 communicating with the supply tube 12. Thus, in this position of the plug, the valve is open and material flows through the discharge port and into the bag positioned below the valve. To close the valve, the plug is turned in one direction or the other far enough to swing the ports 25 and 27 out of alinement with housing ports 14 and 29.
In the present instance, the housing comprises a block formed with a cylindrical bore 31 in which the plug is journaled with stub shafts 32 and 33 projecting from the ends of the plug and into bearings 34 and 35 in end plates 37 and 38 fastened to the sides of the block by screws 39. The feeding and discharge ports 29 and 14 are disposed above and below the plug, and the passage 24 is a diametrical bore through the plug. A nozzle 40 fastened to the underside of the housing is formed with a bore 41 encircling the discharge port to direct the flow from the discharge port into the spot 15.
To oscillate the plug 23 back and forth in timed relation with the advance of the bags 11, the stub shaft 33 is projected through the end plate 38 and an arcuate gear segment 42 is mounted on the projecting end to be engaged by a rack 43 operated by a reciprocating power actuator 44. Herein, the actuator takes the form of a piston (not shown) guided in an air cylinder 45 with the rack 43 fast on the piston rod 47 for back and forth movement therewith. On O-ring 48 encircling the stub shaft 33 within a sleeve 49 intgeral with the plate 38 prevents leakage of liquid from the housing around the shaft.
As the piston rod moves endwise back and forth, the rack 43 oscillates the segment 42 and the plug 23 through an arc corresponding to the length of the stroke of the stroke of the piston, this stroke being sufiiciently long to turn the outlet port out of communication with the discharge port as shown in FIG. 2. The actuator preferably operates with a snap action for precise control of the dispensed amounts. It will be evident that one actuator and one rack are capable of operating a plurality of similar valves mounted in a line.
When a solid material such as strawberries is included in the product being dispensed, it is desirable to provide a positive cutting action in the closing of the valve. For this purpose, a knife edge is formed on the plug around the outlet port 27 and the housing edge 46 defining the discharge port 14 is shaped to cooperate with the knife edge in chopping off any solid material disposed between the edges when the valve snaps closed.
The present invention contemplates the provision of novel means for preventing delayed dripping of liquid from the valve after the fiow through the valve is stopped and during indexing of the package conveyor thereby to prevent contamination of the seal areas 22 of packages moving under the valve and also avoiding spattering of the packaging machine and the area around the machine. For this purpose, a jet 50 is provided on one side of the discharge port 14 to direct flow of gas, usually air, across the port immediately after closing of the valve. Accordingly, all loose material clinging to the exposed portion of the plug 23 or the adjacent portions of the housing is wiped away from the valve to fall into the package below the valve, before the package or the spout is moved, instead of dropping onto the floor, collecting on parts of the machine, or fouling one of the surfaces of the packages moving under the valve.
In the present instance, two air jets 50 are provided and each comprises a duct opening at one end into a tapped bore 51 in the outer side of the housing and at the otherend into the discharge port 14 just above the wall 28 below the plug. Fittings 52 are threaded into the bores 51 and connected to lines 53 communicating with a suitable source (not shown) of air under pressure. Preferably, air is supplied continuously through the lines 53 and the two ducts are positioned directly opposite each other to provide a balanced air flow out through the nozzle. Air pressure of five to fifteen p.s.i. has been found to be satisfactory for strawberries in juice.
To insure thorough cleaning of the entire exposed area of the plug 23, the ducts 50 open into the discharge port 14 as close to the periphery of the plug as is possible without breaking the edge 46. Thus, the air flow passes across and close to the portions of the plug just above the ducts as well as the portion in the middle of the port 14.
The nozzle bore 41 comprises a downwardly tapering conical wall terminating in a lower knife edge 54. With this form, there are no surfaces within the nozzle to cause a product build-up therein, and the balanced air flow through the nozzle is effective to wipe it free of all drops that may tend to cling to the wall when the valve is closed. This flow also cleans knife edge 54.
From the foregoing, it will be seen that a valve constructed as described herein is wiped clean of any loose material as soon as the valve is closed so that the drops fall While the bags 11 are positioned to catch them. Thus, there is no delayed dripping from the valve and all spattering is avoided in a relatively simple and inexpensive manner.
