arrow/5x3 United States Patent Office Patented Sept. 29, 1970 3,530,971 CONTAINER RINSING AND COMBINING APPARATUS Momir Babunovic, Des Peres, Mo., assignor to Barry- Wehmiller Company, St. Louis, Mo., a corporation of Missouri Filed Mar. 4, 1968, Ser. No. 710,141 Int. Cl. B65g 47/24 US. Cl. 198-33 9 Claims ABSTRACT OF THE DISCLOSURE Apparatus for handling containers at high speed and in which the containers are run through a rinsing operation prior to filling and are then combined so that several rinsing operation stations can be utilized to make up the capacity of a high speed filler. The apparatus is constructed to allow time for the rinsing phase which includes injecting draining and flinging the rinsing fluid, all in conveyors having a relatively long run that is doubled back on itself for conserving floor space.

This invention relates to apparatus for rinsing a large volume of containers in a plurality of stations and collecting the rinsed containers in a combined stream sufiicient to supply the capacity of high speed processing equipment such as fillers.

Some of the problems that are associated with glass containers are care required to prevent breakage, and maximum speed of handling in a crowd to minimize breakage, scuffing and chipping. There is also the further problem with certain containers that the restricted necks limit the rinsing speed which could be greatlyimproved if the necks were larger. This latter problem is especially true of the prevailing types of beverage bottles in use.

It is, therefore, a general object of this invention to provide apparatus that can avoid the above recited and other problems while handling containers at greatly increased speeds.

An important specific object of this invention is to provide novel means to rinse containers in a compact path of travel so that space conservation is achieved.

Another important object of this invention is to improve the operation of rinsers so that certain motions and forces can be utilized to result in simplification of the apparatus.

A further object of this invention is to provide a compact rinser apparatus in which containers are handled in continuous single file order and are loaded and unloaded from carrier pockets by an improved and novel arrangement of swinging the pockets transversely to the line of travel.

Still another object of the present invention is to provide a compact and simplified container rinser apparatus which is arranged to receive and discharge containers at high speeds, to quickly and surely invert the containers for rinsing and draining and to quickly restore the containers to normal upright position prior to discharge.

Other and further objects of the present invention will be set forth in connection with the disclosure of a preferred embodiment which is shown in the drawings.

The preferred embodiment of this invention includes a high speed single line conveyor having container holding pockets articulated so as to be able to swing about an axis parallel to the direction of motion between erect and pendent positions, whereby pocket position controlling means can be relied upon to retain the pockets in either the erect or pendent positions as well as to smoothly and rapidly swing the pockets between the pendent and erect positions. The preferred apparatus also includes rotary means for loading and unloading containers during movement of the conveyor pockets, together with means for elevating the containers into the pockets at the loading station and to lower the containers out of the pockets at the discharge station. The preferred embodiment of the present invention also includes a system for utilizing a plurality of rinsers, each having the above general characteristics, in which the rinsers cooperate to deliver the rinsed containers to high speed conveyor means which will combine the discharge of all of the rinsers into a high speed flow suitable for continuously supplying processing equipment such as high speed fillers.

The rinsing of containers is a necessary operation in order to be sure that foreign matter is not in the containers fed to a filling machine. This operation is especially desirable with new containers arriving from the manufacturing source so that foreign matter can be eliminated. The containers C arrive in mass lots and are collected by the conveyor 15 of FIG. 14 and moved into slots 16 formed by the angularly related walls 17. The slots feed the containers C onto table top conveyors 18, one of which is best seen in FIGS. 1 and 2 with guide rails 19 and 20. The conveyors 18 direct the containers C onto a rotary table 21 from which they enter the rinseI apparatus R. The system of FIG. 14 includes a multiple arrangement of rinsers R which are essentially the same, and which discharge the rinsed containers onto a transfer table 22 where the direction of movement is changed and the flow is combined into conveyors 23 and 24 which operate at a speed sufiicient to combine the flow from two of the rinsers R. The conveyors 23 and 24 may feed any suitable apparatus, such as fillers (not shown), or they may feed a third conveyor which operates at a speed suflicient to combine the output from conveyors 23 and 24. The combining function of conveyors 23, 24 and 25 is more particularly set forth in the application for patent of Momir Babunovic, John C. Kay and Jerome F. Shea, Ser. No. 685,838, filed Nov. 27, 1967.

Each rinser R of FIG. 14 is essentially the same and, therefore it will not be necessary to describe the details of more than one, as it may be assumed that the other rinsers are the equivalent in all essential matters. Attention will now be directed to FIGS. 1 and 2, and to other views as is deemed important for a description of a typical rinser R.

As has been pointed out, the containers brought in on conveyor 18 are displaced by guides 19 and 20 on the rotary table 21 which is suitably mounted on a drive shaft 27 driven by a sprocket chain 28 on sprocket 29 located below the frame structure 30 which makes up the support for the various components. Part of the frame consists of a longitudinal beam 31 extending lengthwise of the apparatus and supported by legs 32. The beam also operatively supports a driven shaft 33 at one end and an idler shaft 34 at the other end. A prime mover M delivers power at M to drive shaft 33 and also delivers power at M" to a third shaft 35 (FIG. 1). The shaft 35 has a sprocket 36 which through chain 28 drives sprocket 29 for shaft 27 (FIG. 2). As will appear presently the shaft 33 has sprocket 37 (FIG. 12) which by chain 38 drives sprocket 39 on shaft 40 (see (FIG. 9). The shaft 40 is bearinged in an arm 41 of the frame structure 30 and has a bevel gear 42 meshed with a similar gear 43 which drives shaft 44 and this results in rotation of a loading cam member 45 later to be referred to.

In FIGS. 1 and 2 the containers C reaching the rotary table 21 are aligned in the peripheral recesses 47 of a starwheel 48 secured to the upper end of shaft 27. The guide fence 20 continues about the starwheel 48 to retain the containers in the recesses until they are brought into the loading zone of the rinser R.

The rinser R has a driven sprocket 50 on the upper end of shaft 33 which meshes with a conveyor chain 51 (FIG. 12) trained about an idler sprocket 52 mounted on the idler shaft 34 (FIG. 1). The main longitudinal beam 31 of the frame 30 carries longitudinal fixed channel guides 53 and 54 (FIGS. 1 and 2) in which the chain 51 is guided. The chain links are articulated by vertically directed pins 55 (FIG. 10) and each pair of such pins 55 carries a. slide bracket 56 having an upper horizontal portion 56' (FIG. 8) which engages in the chain guides 53 and 54 except where the chain is supported by the sprockets 50 and 52. The lower portion 57 of each slide bracket 56 forms a pivot journal for an arm 58 having a roller 59 on its outer end (best seen in FIGS. 6, 7, 9, l1 and 12). The arms 58 pivot about the bracket portions 57 such that the container pockets 60 mounted on the arms 58 may pivot therewith, as is best illustrated in FIGS. 6, 7, 8 and 9.

Control over the pivoting action of the pockets 60 is achieved by fixed rails extending about the beam 31. For example, in FIG. 2 where the pockets 60 are vertically erect rails 61 and 62 holds the rollers 59 therebetween such that the pivot arms 58 are horizontal. The rails 61 and 62 are carried by U-shaped elements 63 fixed by brackets 64 carried on the frame 30. The elements 63 and brackets are spaced at suitable intervals about the frame to allow the rails to be bent in suitable ways such that the container pockets may be pivoted outwardly and downwardly to a pendant position in which the containers are inverted. This arrangement is best seen in FIG. 4 where the pockets 60 move leftwardly. The right hand portions of the rails 61 and 62 are arranged with the rail 61 under rail 62 (as in FIG. 9). As the rails enter the twist area, rail 61 is first bent down and then is reversed to emerge at the left above rail 62, and rail 62' is bent down and emerges below rail 61. The spacing between rails is, of course, maintained so no binding occurs on the rollers 59. The progressive twist of the rails can be seen by viewing FIGS. 9, 6,7 and 8, in order, and following the rollers 59. In this progression of views, when related to FIG. 4 it is revealed that the pockets 60 of FIG. 4 swing out away from the viewer and then become pendent. This action is confirmed in the plan view of FIG. 1.

As the pockets 60 pivot outwardly and finally reach the pendent atttiude the containers are moved by gravity and the pivoting action of the pockets into the pocket neck 60:: which is closed so that the containers open ends emerge and are in position to pass directly over the rinser fluid manifold 65 (FIGS. 4 and 8). The manifold 65 is provided with a plurality of upwardly directed nozzles 66 to deliver the rinse fluid into and over the outside of the containers C. The containers, once they become inverted, remain inverted during the travel outwardly from the loading station and about the idler sprocket 52 and for a substantial part of the travel back toward sprocket 50.

Turning now to FIGS. 1, 2 and 9 it can be seen that as the containers C are delivered by the starwheel 48 to the successive pockets 60 arriving from the sprocket 50 on the out travel of the pockets 60 toward sprocket 52, the pockets present the outwardly open sides 60b to the containers. The pockets are held somewhat above the containers so the necks C pass under the closed pocket necks 60a and are captured in the pockets 60. After being captured by the pockets 60 the containers C are transferred to a fixed bar 67 which engages the bottom surfaces. The bar 67 is best seen in FIGS. 4 and 9, and the transfer is effected by the loading cam 45. The cam 45 has a disc body formed with lifting lobes 45a which move in the direction of container motion (counterclockwise as seen in FIG. 4). The successive lobes push the containers upwardly in the pockets 60 and the elevating action deposits the containers upon the upper edge of the bar 67 where they remain supported. The bar 67 is twisted in appropriate fashion to match the twist of the rails 61 and 62 (FIGS. 4, 5, 6, and 7) so that the neck portion C of the containers remain captured by the pockets 60 until the outward pivoting of the pockets has gone sufficiently far to cause the containers to slide fully into the pocket necks 60a. The action of the loading cam 45 and bar 67 is greatly assisted by the high speed travel of the pockets 60 so that the outward pivoting (FIG. 6) of the pockets 60 from the base ends of the containers flings the containers fully into the closed neck portion 60a of each pocket. Complete control of each container is thus assured.

Having moved out to the idler sprockets 52 and returned on the inward pass of the conveyor chain 51, the pendent pockets 60 (FIG. l3) are again swung to the vertically erect attitude by a second twisted arrangement of the rails 61 and 62 which guide the rollers 59 back to horizontal positions (FIG. 2, at the left side). During the reverse twist in rails 61 and 62, the bottoms of the containers engage on a cam bar which has an upwardly directed portion 68 effective to retain the containers fully in the respective pockets 60 until the pockets are fully erect. The cam bar includes a container lowering ramp 69 (FIG. 2) which coincides with guard rails 70' carried on stanchions 71 attached to the frame 30. The lowering ram 69 has a horizontally directed portion 72 which has its upper edge at the same level with the rotary table 22 mounted on shaft 35.

The pockets 60 move the containers into registery with peripheral recesses 73 of a pair of starwheels 74 carried by shaft 35 so as to rotate with the table 22. The guard rails 70 curve over a portion of the table 22 until the containers rest thereon. The curved travel of the pockets 60 at the table 22 cause the containers to move out toward the starwheel recesses 73 such that a pick-off rail 75 (FIG. 1) can operate to cause the containers to leave the pockets 60 and move circularly with the table 22 and starwheels 74. The final operation of the table 22 and starwheels 74 is to register the containers with alternate pockets 76 carried on the discharge conveyor 23.

The operation of the rinser apparatus R described in FIGS. 1 to 13 is understood to be typical of each rinser R shown in FIG. 14. To review the important aspects of the rinsers R, it can be understood now that containers C are fed to each rotary loading table 21 and are caused to traverse a curved path to bring the speed up to that of the rinser conveyor 51 so the containers are smoothly deposited in the pockets 60. A cam 45 at each loading station raises the containers into successive pockets 60 and a fixed cam bar 67 holds the containers in the pockets during the outward and downward pivoting action of the pockets to invert the containers over the rinser spray nozzles 66. The containers are thoroughly rinsed and then remain pendent during the outward and return travel so that sufiicient time is provided for drainage. The pendent pockets then go through a rapid reinverting pivoting action at the erecting station, which action throws off the rinse fluid in a flinging motion due to the high speed, and keeps the containers securely in the pockets until the fixed cam bar 68 engages the container bottoms to control the same. Thereafter the cam bar ramp 69 lowers the containers to the level of the rotary discharge table 22 and the now rinsed containers are transferred from the table 22 to the discharge conveyor 23 (or conveyor 24 as the case may be) for combining with containers from adjacent rinsers R. In such an apparatus layout the rinsers can be greatly compacted and run at high speed to match the capacity of the combining conveyors 23 and 24. The components of each rinser R are arranged to promote rapid and secure loading and unloading of the containers. The flinging action of the swinging pockets 60 cause the containers to stay in the pockets during the inverting and erecting phases, and this is a significant improvement in rinsers as it allows the use of simple means to achieve the good results evident in this embodiment. This flinging action is assisted by providing closed neck portions 60a on each pocket 60.

Turning now to FIGS. 15 to 22 inclusive there is disclosed a modification which may also be a preferred embodiment of the apparatus. The apparatus R includes a suitable general frame 77 having a bearing housing 78 for a shaft 79 driven by a prime mover PM of any convenient character. The shaft 79 drives a rotary plate 80 similar to plate 22 in FIG. 1, and peripherally recessed star wheels 81 are also driven by the shaft 79. An arm 77' of the general frame 77 operatively supports a shaft 82 (FIG. 16) which drives a rotary plate 83 similar to plate 21 in FIG. 1. The shaft 82 also drives a pair of peripherally recessed star wheels 84 (like starwheels 48 in FIG. 1) which regulate the feeding of the containers C between the delivery conveyor 85 and the conveyor means in the present apparatus. Shaft 82 is provided with a sprocket 86 connected by chain 87 to a sprocket 88 on shaft 79.

The shaft 89 in FIG. 15 is driven from the prime mover PM and operates a conveyor sprocket (not shown but similar to sprocket 50 in FIG. 1) which moves the container pockets 60. The individual pockets 60 are mounted on selected links 90 (FIG. 16) of a suitable roller chain which runs in a guide channel 91 having marginal flanges 92 and 93 at top and bottom to guide the links 90 of the roller chain by the link ears 94. The link ears carry a pivot bracket 95 which is provided along its lower margin with a bearing boss 96 for a pivot pin 97. The boss 96 (FIG. 21) is bifurcated to receive therebetween the bifurcations of a yoke bracket 98 (FIGS. 15 and 21) which carries at its lower end a roller element 99. The roller 99 is made to follow a rail 100 suitably supported from the general frame 77 (not necessary to show). The bracket 98 also is part of a container control leaf 101 which moves with the motion of the bracket roller 99 on the rail 100. The control leaf 101 isnormally positioned in a substantially horizontal attitude as the conveyor chain traverses the end turn (FIG. 15) about the axis of shaft 89, and the leaf is caused to pass just beneath the rotary table (FIG. 15) as well as the table 83 (FIG. 16).

Each pocket 60 is formed with an extension 102 (FIG. 21) that forms a bearing hub 103 mounted on pin 97. The hub 103 is provided with an arm 104 which carries a roller 105 adapted to cooperate with rails 106 and 107 suitably supported in spaced relation by bracket means 108 (FIG. 16). It is understood that bracket means 108 and the rails 106 and 107 vary in shape and location about the apparatus in order to control the position of the pockets 60, and the rail also varies its position to regulate the control means 101 relative to the pockets 60.

The shape and relationship of the rails 106 and 107, as seen in FIGS. 17, l8, l9 and 20, causes the roller to tilt the arm 104 which swings the pocket 60 clockwise about pivot pin 97 from the erect position of FIG. 15 to the inverted position of FIG. 20. This action occurs in a relatively short time and thus the container C is forced or flung fully into the pocket. During the pocket swing, the rail 100 also curves about and holds the control leaf 101 against the bottom of the container so that in the jet rinse position of FIG. 20 the force of the jet cannot lift the container. However, prior to reaching the position of FIG. 18 the rail 100, seen in FIG. 16, holds the leaf 101 in a position to receive the bottom of the container and thereby support the container. A guard rail 109 (FIGS. 16 and 17) aids in holding the container until the curve of the rail 100 causes the leaf 101 to lift the container fully into the closed neck portion of the pocket 60.

The apparatus of FIGS. 15 and 21, is arranged to swing the pockets with the containers therein to an inverted rinse and drain position (FIG. 15) and, after a period of drain time, to swing the pockets to the erect position (FIG. 22) in preparation for discharging the rinsed containers from the pockets 60 and reloading from the table 83 (FIG. 16). The rinsed containers are discharged onto rotary table 80 (FIGS. 15 and 22) where with the aid of guide rails 81 they are placed on a high speed conveyor represented by the skid bars 80a and the chain actuated pockets 81a. The pockets 81a work in conjunction with guide rails 110 to retain the containers in transport position. The lowering of the containers onto table 80 is effected by the control leaf 101 being moved as its arm 98 and roller 99 follows the rail 100 in the manner disclosed in FIG. 22.

The operation of the modified apparatus of FIGS. 15 to 22 is substantially like that for the apparatus of FIG. 1 and no detailed description is deemed necessary. The difference in apparatus is that the control leaf 101 of FIG. 17 acts throughout the loading, rinsing, draining and unloading phases to maintain engagement with the container in each pocket. It is understood, of course, that the container rinser apparatus R of FIGS. 15 to 22 may be used in place of the apparatus R in the system shown in FIG. 14.

The foregoing description of the preferred embodiment is not to be interpreted as unduly limiting the scope of apparatus which will achieve the end result sought herein. Furthermore, having read and understood the foregoing description in connection with the accompanying drawings, it will become evident to those skilled in this art that changes and modifications might be made in the operating components.
