Filed Ang. 2li, 1959, Ser. No. 835,048 12 Claims. (Cl. 531-281) yThis invention relates to improvements in apparatus for packaging uent materials.

It is a general object of this invention to provide an improved apparatus for dispensing a measured quantity of fluent material into a container, which apparatus is of simple and economical construction and which can be readily disassembled for cleaning without the use of tools.

Another object of this invention is to provide a packaging apparatus including a piston type measuring device, a control valve for controlling flow to and from the measuring device, a cap dispensing apparatus, and a cap applying device, together with an improved common actuator connected to the several elements for operating the same in timed relation to each other to dispense a measured quantity of material into the container and thereafter apply a cap to the container.

A more particular object of this invention is to provide a dispensing apparatus including a measuring cylinder having a plunger therein and a three-way valve movable between intake and discharge positions to control the flow of material to and from the cylinder, which apparatus has a single actuating lever operative during movement of the lever in one direction to initially move the valve to its intake position and thereafter retract the plunger to draw a charge into the cylinder and operative during movement of the lever in the other direction to initially move the valve to its discharge position and thereafter extend the plunger and discharge a measured quantity of material from the cylinder.

An additional object of this invention is to provide a dispensing apparatus in accordance with the foregoing object and including a cap magazine and a cap applying device and a slide for removing a cap from the magazine and for carrying the same with a container to the cap applying device, together with mechanism connected to the common actuating lever for operating the slide and capping apparatus in response to movement of the actuating lever.

These, together with various ancillary objects and advantages of this invention will be more readily appreciated as the same becomes better understood by reference to the following detailed description when taken in connection with the accompanying drawings wherein:

FIG. 9 is a fragmentary sectional view taken on the plane B-B of FiG. 3 and illustrating the position of the cap dispenser and cap applying apparatus when the actuating lever is in its lowered position.

The packaging apparatus of the present invention is generally adapted for use in dispensing measured quantities of fluent materials into containers and, in general, includes a piston type dispenser 10; a valve 11 for controlling the ilow of material to and from the piston dispenser; a cap dispensing mechanism 12, and a cap applying mechanism 13. The several instrumentalities are operated 4by a common actuator which, in the embodiment illustrated, is arranged for manual operation and includes a lever 14 movable from a iirst position to a second position and back.

The dispenser 10 comprises an elongated generally horizontally extending body 15 which defines a measuring cylinder or chamber r16. The body 15 is removably supported on a base and, as best shown in FIG. 7, has a depending lug 17 thereon which is removably received in a block 18 and retained in position thereon by a set screw 19. The block 1S is supported on a plurality of legs 21-23 which extend outwardly and downwardly from the block to support the same on a supporting surface such as a counter-top Y24. A piston 25 is slidably ydisposed in the cylinder and has a collector groove 26 extending therearound at its inner end. For reasons set forth more fully hereinafter, an elongated slot 27 is formed in the outer end of the piston 25. The valve 11 is formed in the body 15 at the forward end of the cylinder 16 and includes a valve chamber 29 which communicates through a passage 31 with the measuring cylinder 16. The valve also includes inlet and discharge passages 32 and 33 and a rotary plug type valve 34 having a flow passage 35 operative in one position of Athe valve member to communicate the passage 31 with the inlet 32 and, in the other position thereof shown in FIG. 7, to communicate the passage 31 with the outlet 33. The valve chamber 29 and plug 34 are preferably axially tapered as shown in FIG. 6 to maintain Aa close working fit between the parts. The material may bev supplied to the inlet passage 32 in any desired manner and, as herein shown, a hopper 37 is formed with a spout 38'on its lower end which is detachably received in a counterbore 39 formed in the upper side of the body 15.

The valve 11 and piston type dispenser 10 are operated in timed sequence by a common actuator. The actuator includes a shaft 41 mounted in the body 15 for rotation about an axis parallel to the axis of the rotary valve member 34. The operating lever'14 is connected to the left hand end of the rod and extends outwardly'and forwardly and terminates in a knob 43 (see FIG. 5);v A valve operator is connected to one end of the shaft and includes the sector plate 45 which is supported on'one end of the shaft 41 for rotation relative thereto. The sector plate is formed with teeth 46 on one end thereof which mesh with the teeth 47 formed on the outer end of the valve member 34. Preferably, the teeth 47 on the valve member are located inwardly of the periphery of the valve member to form a shoulder 34a yon the valve member against which the teeth 46 of the vsector plate abut to maintain the valve member in assembled relation on the body 15. The angular movement of the valve member 34 between its intake and discharge positions is limited by means of a stop pin 49 on the body 15 and which extends into an arcuate slot 51 in the sector plate. The pin 49 engages the sector plate 45 at one end of the slot, when the valve member is in its intake position shown in FIG. l, and engages the pin 49 at the other end of the slot when the valve member is in its discharge position shown in FIG. 7.

The sector plate 45 is moved from one limiting position to the other by means of an arm 53 which is connected to the shaft 41 for turning movement therewith and for limiting tilting movement at the direction transverse to the shaft. As best shown in FIG. 6, the shaft 41 is formed with a flat blade portion 54 at its end which defines a shoulder 55. The -blade portion has a notch 56 formed therein and the arm 53 has an elongated slot 57 having a length only slightly greater than the depth of the `blade portion between the base of the notch 56 and the underside thereof. The underside of the blade portion is beveled at 59 at a point spaced outwardly from the shoulder 55 to permit the arm 53 to pivot about the notch 56 in a direction transverse to the shaft. A hub 61 is provided on the arm and engages opposite sides of the blade 54 to guide the arm during the aforedescribed pivotal movement. The arm is yieldably urged in a counterclockwise direction as vewed in FIG. 6, in a manner hereinafter described, to releasably retain the arm in position on the shaft 41 and to also urge the arm to- 0 ward the sector plate 45. A dog 62 is formed on the inner facepof the arm 53 and is arranged to engage a shoulder 45a on the sector plate 45, when the operating lever 14 is moved in a clockwise direction as viewed in FIGS. 1 and 5, and to engage a second shoulder 45b on the sector plate when the arm is moved in a counterclockwise direction.

When the dog 62 engages the shoulders 45a or 45h it moves the sector plate 45 with the shaft 41 and therebymoves the valve 34 from one position to the next. In order to interrupt movement of the valve member after it reaches its succeeding position, a cam member herein shown in the form of a beveled nose 63 on the valve member 34, is arranged to engage the end of the arm 53 and cam the same outwardly to disengage the dog 62 from the sector plate. As is apparent from FIGS. and 6, the earn is arranged to tilt the arm 53 away from the sector plate, at about the time the pin 49 engages one end or the other of the slot 51. Thus, during the initial movement of the lever 42 from its raised position shown in FIG. 1 'toward its lowered position, the dog 62 en- 'gages the sector plate to rotate the valve member 34 to its discharge position. When the valve member reaches its discharge position, the cam nose 63 cams the lever v53 outwardly and disengages the same from the sector plate. In accordance with the present invention, provision is made for thereafter operating the piston to discharge a measured quantity of material from the measuring cylinder 16. The upper edge of the sector plate is preferably beveled as indicated at 64 (see FIG. 6) to facilitate the aforedescribed tilting of the arm 53 relative tothe sector plate.

The piston 25 is extended and retracted by means of a pair of

arms

65 and 66 connected to the shaft 41 for rotation therewith. The arm 65 is herein shown rigidly attached to the shaft 41 at one side of the body 15, and the arm 66 is conveniently formed integrally with the arm 53 to extend from the side of the shaft opposite the arm 53. A generally U-shaped bail 67 has the web portion 67a thereof disposed in the elongated slot 27 in the piston. Pintles 68 are formed on the free ends of the bail and are adapted to he received in apertures 69 formed in the

arms

65 and 66. A plurality of sets of openings or apertures 69 may be provided in each of the arms 65, to 'enable adjustment of Athe stroke of the piston in fixed increments, and a set screw 71 is threaded into the piston 25 and intersects the slot 27 therein to adjust the lost motion between the bail and the piston. The bail is formed of a resilient wire material and is bent so as to yieldably press the outer ends thereof apart. This urges the arm 66 and hence the arm 53 in a counterclockwise direction as viewed in FIG. 6 to yieldably maintain the dog in engagement with the sector plate and also to retain the arm 53 in assembled relation on the shaft. When the operating handle or lever 14 is in its raised position shown in FIG. l, the piston 25 is retracted and, during the initial movement of the lever toward its lowered position, the bail 67 moves along the slot 27. The slot i's advantageously made sufficiently long so that the bail does not engage the inner end of the slot until after the `valve 34 has been moved to its discharge position shown in FIG. 7. Thereafter, further movement of the lever toward its lowered position will extend the piston to discharge material from the measuring cylinder. Similarly, when the lever is in its lowered position, the bail is at the inner end of the slot 27 and, during the initial movement of the lever to its raised position, the bail merely moves along the slot and does not engage the adjusting Screw 71 until yafter the valve member 34 has been moved to its intake position shown in FIG. 1.

The containers 96 to be filled are advanced to a position below the outlet 33 along a platform 73 having guide anges along opposite sides thereof. The platform is conveniently formed with an upwardly inclined portion 73a (see FIG. l) so that the containers are urged by gravity to a position below the valve outlet. The platform 73 is conveniently supported on the block 18 and for this purpose has 4a mounting plate 74 along the rear edge thereof which is supported on pins 75 carried by the block. As best shown in FIG. 7, the body 15 has a depending rib 76 which overlies the upper edge of the mounting plate 74 to aid in retaining the same in position on the pins. With this arrangement, the platform can be removed by lifting the Same upwardly to pivot the plate 74 about its upper edge until it clears the pins 75 at which time it can be lowered away from the lip 76. For reasons set forth hereinafter, the platform 73 is formed with a transversely extending portion 73b which extends forwardly from the main platform 73 and terminates in a downwardly inclined portion 73C which guides the containers onto the counter top 24.

The cap dispensing mechanism 12 is also detachably mounted on the body 15 and includes a generally dat slide bracket 81 having depending ears 82 at one end which are pivotally mounted by a pin 83. The pin 83 extends through a boss 84 formed at the underside of the body 15. The plate 81 has an opening 85 adjacent the free end thereof and a cap magazine 86 is attached to the plate 81 `and extends upwardly Varound the opening 85 to Support a plurality of caps 87. Spaced guide strips 89 are attached to the plate 31 and are spaced therebelow by bars 91 to dene a guideway for the cap ejector slide 92. The caps 87 in the magazine move downwardly by gravity and the lowermost cap rests upon the strips 89. The forward end of the ejector plate 92 is formed with a concave recess 92a (see FIG. 4) which engages the lowermost cap and removes the same from the stack as the slide is extended. A container ejector plate 93 is attached to the cap ejector plate 92 and is spaced therebelow by a bar 94. The container ejector plate has an arcuate recess 93a in its nose portion arranged to engage the upper end of the container 96 to advance the same with the cap. As is apparent from FIG. 8, the recesses 92a and 93a are arranged so as to advance the cap in registry withthe open top of the container 96 whereby the cap drops onto the container after the cap moves beyond the ends of the guide strips 89. The

slides

92 and 93 are ment of the lever 14 from its raised position to its lower position and back. For this purpose, an arm 97 is attached to the shaft 41 for rotation therewith yand as herein shown is formed integrally with the arm 65 at the left hand end of the shaft y41. The arm has a pintle 98 yat its outer end which extends into a vertically extending slot 99 formed in a slide operating plate 101. As best shown in FIG. 3, the slide plate 101 is connected to the container ejector plate 93 along one side edge of the latter. When the slide 93 is extended, the plate 101 projects into the path of movement of the containers 96 along the platform 73 (see FIG. 3) `and is advantageously so arranged with respect to the outlet 33 of the valve as to stop `a container in filling position below the valve. When the slide 93 is retracted, the container can be advanced to a position adjacent the cap magazine 816. As will be noted from FIG. 4, the cap magazine is positioned slightly in advance of the outlet 33 ofthe valve so that the container ejector plate engages the container slightly before the cap ejector plate engages a cap in the magazine to remove the latter.

The cap applying mechanism 13 comprises a head 105 which -is positioned yalong the path of movement of the containers and caps -as they are advanced by the

slides

92 and 93. The head 105 is supported at the free end of a plate 106 which is pivotally mounted at its other end by means of laterally extending ears 107 which are supported on the pin 83. A spacer sleeve 108 (see FIGS. 3 and 4) is provided on the pin to maintain the proper spacing between -the plate 106 and the body. A spring 109 is interposed between the plate 106 and the plate 81 to yieldably urge the plate and head 105 to a raised position in which the head is above the path of movement of the `caps and containers. As is apparent from FIG. 3, the plate 106 is cut away as indicated at 106:1 to extend around the cap magazine S6 to permit free vertical movement of the cap applying device. A cam plate 111 is attached to one side of the plate 108 and terminates in `a laterally extending ear 112 (see FIG. 3). A further arm 114 is connected `to the shaft for rotation therewith, which arm is also conveniently formed integrally with the arm 65. The arm 114 extends outwardly and is angularly related with respect to the arm 97 so as to engage the earr 112. and press the head 105 downwardly to seat the cap on the container, as the lever 14 is moved to its lowered position. Stops 115 `and 116 are provided on the hub `formed by the

levers

65, 97 and 114 and are arranged to engage a stop pin 117 to limit the angular movement of the lever between preselected upper and lower positions.

From the foregoing it is thought that the operation of the device will be readily understood. Briefly, when the operating lever 14 is in its raised position, the Valve 11 will be in its intake position and the piston 25 4fully retracted as shown in FIG. l, and the cap applying mechanism 13 will be in its depressed position while the slides will be extended, as shown in FIG. 2. As the operating lever is moved downwardly, the dog 62 on the arm 53 engages the shoulder 45u on the sector plate to rotate the sector plate and hence the valve 34 toward its discharge position. As the valve approaches its discharge position, the arm 53 r-ides over the cam nose 63 and disengages the dog from the sector plate. During this time, the bail 67 has moved along the slot 27 in the piston. As the lever is moved further downwardly, the piston is extended 4and the arm 53 rides across the face of the sector plate until it drops behind the other shoulder 45b. As the piston is extended, it discharges a measured quantity of material through `the outlet 33 into ya container on the platform 73 therebelow. When the lever 14 is in the raised position previously described, the

slides

92 and 93 are extended. The plate 101 along the edge of the slide projects into the path of movement of the containers on the platforml 73 and is spaced from the delivery outlet 33 a dis-tance less than the diameter of the container so as to stop the same in proper lling position. As the lever 14 is moved downwardly, the slides are retracted and, as the lever appreaches its lower position, the arm 114 engages the plate 111 to move the cap lapplying anvil 105 downwardly to seat the cap on the mouth of the container as shown in FIG. 9.

When the lever 14 is returned to its raised position, the dog 62 initially engages the shoulder 4511 to rotate the cam plate in a counterclockwise direction as viewed in FIGS. l and 5. When the valve reaches its intake position, the cam nose 63 swings the arm 53 outwardly to disengage the `dog `62 from the sector plate. During this time, Ithe bail 46'7 has been moving along the slot 27 and about the time the valve reaches its intake position, the bail strikes the adjustable thumb screw 71 whereby further movement of the lever will retract the piston to draw a charge of material into the measuring cylinder. During the aforedescribed raising of the lever 14 the arm 114 rst disengages the cam plate 111` to permit the anvil 105 to raise. The arm 97 then moves the

slides

92 and 93 to their extended position to simultaneously advance -a cap and the container 96 to a position below the anvil 105.

The device can be readily disassembled for cleaning by merely bowing the bail 67 inwardly to release the pintles 68 from the apertures 69. The piston 25 can then be retracted. in addition, the arm 53 can be swung outwardly and then disengaged from the notch 56 on the shaft 41. This enables removal of the arms 53 and sector plate 45. The valve is retained in position by the sector plate engaging the shoulder 34a on the end thereof so that the valve can also be removed after the sector plate has been removed. The

arms

65, 97 and 114 are formed integrally with the `shaft 41 and lever 42 and are removed as a unit therewith. By withdrawing the pin 83, the cap dispensing and cap rejecting mechanisms can be removed from the body 15 and disassembled from each other.
