GBUETTER, 0F CLEVELAND, GHIO, ASSIGNOR TO THE LIQUID GARBONIC GOR- PORATION, OF CHICAGO, ILLINOIS, A CORPORATION OF DELAWARE BOTTLE CLEANING APPARATUS Application filed January 23, 1931.
This invention relates to apparatus for cleaning bottles and more particularly to ap paratus of the general type wherein the bottles are mounted on transverse carriers flexibly connected and constituting an endless conveyor by which the bottles are advanced intermittently th ough the apparatus and are subjected, during their transit thercthrough, to various interior and exterior treatments with liquid, tl eir exteriors and interiors also being subjected to the action of brushes, as part of the clea -ing treatment.
The particular invention disclosed herein relates more especially to the mechanism for brushing the outsides of the bottles while in transit through an,apparatus of the general character referred to. More limitedly, the invention relates to the means for centering the bottles on the carriers with respect to a series of lifting rods which serve to subject them to the action of cleaning means. An instance of apparatus of the general type to which this invention relates is disclosed in Patent No. 1,313,706 issued to Charles H. Loew and myself on August 19, 1919; also in Patent No. 1,719,8 l4. issued July 9. 1929 to Paul N. Loew and Robert E. McKechnie.
It is the general purpose and object of the invention to enable bottles, while being conducted through an apparatus of the general character aforesaid, to be brushed in a particularly eflicient manner; also to insure that the bottles in each transverse carrier shall be conveniently and effectively aligned with respect to the lifting rods or spindles by which they are lifted from their carriers into operative relation to cleaning mechanism located above the carriers and the conveyor of which the carriers form a part In the accompanying drawings, Fig. 1 represents a side elevation of a part of a bottle washing apparatus of the general type re ferred to, showing three of the transverse series of bottles, together with the brushing mechanisms and the means for lifting the bottles from their seats in the carriers into operative relation to the brushing mechanisms, the brushing mechanisms being shown in the positions occupied'thereby prior to lifting a series of bottles therebetween; Fig.
Serial No. 510,713.
2 is a view similar to Fig. 1, but taken from the opposite side of the apparatus and showing one series of bottles lifted between the brushing mechanisms and the positions of the brushes during this operation; Fig. 3 is a top plan view of a portion of the apparatus shown in Figs. 1 and 2; Fig. l is a sectional view corresponding to the line et l of Fig. 1; Fig. 5 is a longitudinal sectional view through the apparatus shown in the preceding views, the parts being in the positions which they occupy in Fig. 1; Fig. 6 is a view, similar to Fi 5, but showing the parts in the positions which they occupy in Fig. 2; Fig. 7 is a trans verse sectional view through the mechanism for rotating the bottle bottom clamps; and Fig. 8 is a sectional elevation showing the manner of rotating and oscillating the vertically rotating brushes.
In the operation of the portion of the apparatus disclosed herein, the bottle conveyor is moved intermittently along tracks and, when each series of bottles reaches the first brushing station, the mouths of the bottles are automatically centered above their respective lifting rods, the brushes which operate on the sides of the bottles being separated at this time to permit the passage of the bodies of the bottles therethrough; the bottles are then elevated between vertically rotating and horizontally rotating brushes, which are thereby moved toward each other, the brushes rotatin and operating on opposite sides of the bottles; the bottles are then lowered into the seats provided therefor in their transverse carrier, the brushes being separated during this movement; the conveyor is advanced another step, bringing the bottles just treated beneath the horizontally rotating brush and said bottles are then raised from their seats in the carrier a short distance to bring their bottoms into engagement with said brush, the series of bottles next adjacent to the rear being lifted meanwhile between the horizon tally rotating brush and the vertically rotating brushes to have their outer sides cleaned in the manner referred to hereinbefore.
The details of the mechanism by which the foregoing operations are accomplished will now be described.
It will be understood that the major portion of the complete apparatus is enclosed within a casing, a portion of which is indicated at Y, the said apparatus including longitudinally extending rails 1 on which the bottle conveyor, consisting of flexibly connected transverse carriers 2, is supported by rollers 3as is shown generally in the patent to Loew andmyself referred to hereinbefore. As the means for moving the conveyor intermittently along the rails 1 is well known to those skilled in this art, illustration of such mechanism is deemed unnecessary.
For the purpose of lifting the bottles 4 from their respective carriers when each carrier reaches its proper position with respect to the brushes thereabove, I have provided lifting rods A, one for each bottle on a carrier, extending upwardly from a cross-head B. Four bottles are shown in each transverse series and four lifting rods; but it will be understood that the number of bottles constituting each series and the number of lifting rods therefor may be varied in accordance with the capacity of a given apparatus. Each of these lifting rods has its upper end pointed, as indicated at A, and is provided with a tapered seat A therebeneath that engages within the mouth of a bottle thereabove. Opposite ends of the cross-bar B are connected by arms B and links B with a rock shaft X which extends transversely of the apparatus, being mounted in bearings provided therefor in opposite sides of the housing or casing T, as shown at X. B denotes guide brackets which are secured to each end of'the cross-head B and which are adapted to slide upon the vertical guide rods C.
Secured to and extending between the guide rods C is an angle iron member D having guide openings therethrough for the upper portions of the rods A (see Figs. 4 and 5). D denotes another angle iron member which is supported above and at the rear or right of the member D by means of a bracket D secured to the member D.
The bottle centering mechanism consists of laterally spaced angular guide members each having a portion E extending longitudinally of the apparatus and a vertical portion E secured to the vertical branch of the angle iron D, the longitudinal portion of each guide member having a downwardly projecting tongue E, between which tongues the necks of the bottles on a transverse carrier which has been moved above the rods A are positioned. These tongues serve to center the necks of the bottles in one direction with repeat to the corresponding rods A. Vertical tongues E which are mounted on a pair of transversely extending bars E project upwardly toward the portions E of the guide members and serve, when the bars E are moved as pointed out hereinafter, to complete the centering of the mouths of the bottles above the rods A, the tongues then forming in effect a temporary box-like structure around each bottle neck. When the bottle carrier and the bottles therein are being moved, the upwardly extending tongues E are out of the paths of the bottles, being in the position shown by dotted lines in Fig. 4. When a bottle carrier stops above the rods A, the bars E are moved in the following manner transversely of the apparatus to bring the tongues E into aligning relation to the mouths of the bottles, thereby to form with the tongues E a complete centering box for the mouth of each bottle on such carrier. The manner of supporting and moving the bars E whereby the tongues IE will also be moved into appropriate relation to the tongues E, will now be described:
The opposite ends of the bars E are pivotally connected to the downwardly extending arms E of a pair of hell cranks, the bell cranks being pivoted on brackets E projecting from the sides of the apparatus (see Fig. 4). A spring E is connected at one end to the horizontal arm of the bell crank carrying the arm E and at its other end to an eye bolt E which is secured to the guide rod C. A vertical rod E is connected at its upper end to the horizontal arm of the other bell crank and has its lower end slidably mounted in a bracket E carried by the guide bracket B therebeneath, the said rod having a nut E on the lower end thereof normally engaged by the said bracket.
When the cross-head B is in its lowered position, the spring E will be inoperative to rock the bell crank to which it is connected, andthe tongues IE will be in the positions shown in Fig. 4. lVhen the cross-head starts moving upwardly, however, the spring E is free to rock the bell crank to which it connected, thereby moving the bars E trans:- versely and bringing the tongues E into register with the spaces provided between the guide members E. This results in completing the alinement of the mouths of the bottles above the lifting rods A. WVhen the cross-head B is moved downwardly, the bracket E will engage the nut E and will pull downwardly on the rod E thereby moving the bars E to the position shown in Fig. 4, with the tongues E out of the paths of movement of the bottles.
The bottle rotating mechanism is of substantially the same character as that shown in the patent to Loew and myself referred to hereinbefore and in the patent to Loew and McKechnie No. 1,719,844 issued July 19, 1929. This mechanism consists generally of a series of vertically movable angular rods F corresponding in numberand position to ments by sleeves F within a. housing, indicated generally at F (see Figs. 4, 5 and 7 Each sleeve is provided with a spur gear F the gears intermeshing with one another and one of the final gears being provided with a beveled gear F integral therewith which meshes with a beveled gear F on one end of a shaft F which is mounted in an extension of the framework of the apparatus and which shaft is provided at its opposite end with a double spur gear consisting of a. hub havin on the outer end thereof a large gear F and on the lEOt y thereof a small gear F The shaft F 7 is driven by a shaft G extend ing transversely of the apparatus and mounted in brackets G secured to the housing F (see Figs. 1, 3, 5 and 8). To one end of the shaft is fastened a pulley G whereby the shaft is driven from any convenient source of power. On the opposite end of the shaft there is mounted a sprocket G and a gear The shaft G drives the shaft F by means of the G which meshes with the gear F Sprockets G and I are connected by a sprocket chain G H denotes a shaft which is supported on the opposite side of the housing from the shaft G by means of bearing brackets H extending from the said housing and in alignment with the brackets G. One end of the shaft H is provided with a spur gear H and its opposite end with a crank disk H I and 1 denote brackets which extend downwardly from the longitudinal members I located on opposite sides of the machine (see Figs. 1, 2, a and 5). A shaft 1 is mounted for rocking and reciprocatory movements in the said brackets. On one end of the shaft 1 there is loosely mounted a gear I carrying asprocket I Pinned to the shaft I between the brackets I and I, are arms J which extend upwardly and downwardly from the shaft and which are provided at their lower ends with journals l in which is mounted the shaft J carrying the horizontal brush J Secured to the shaft J is a wide gear J which meshes with the gear 1*. r
()n the opposite end of the shaft 1 from the gear 1* and sprocket I is a grooved collar 1 wnich is engaged by the pins on the forked arm of a bell crank I which is pivoted between lugs 1 carried by the bracket I (see Figs. 2 and 1 denotes a connecting rod which has its upper end connected to a crank pin H on the crank H and its lower end connected to the forked end of the other end of the bell crank 1 through. a universal joint connection 1 1 It will be evident that, as the shaft H is revolved, the shaft I will be. reciprocated in its bearings by the connections just described, thereby reciprocating the brush J which is being rotated through the gears 1* and J Mounted within the brackets G and extending inwardly therefrom are sleeves K, through which the shaft G also extends, and a hanger yoke K is rotatably mounted on the extensions K of said sleeves (see Fig. 8). Journal sleeves K extend downwardly from the yoke K and serve as bearings for vertical shafts K each of which has at its upper end a beveled gear and at its lower end a brush Kt. It will be noted that the brushes K are shaped to conform to the contours of the bottles which they engage and that they intermesh' with each other; also that the beveled gears K mesh with beveled gears K on the shaft G. It will be evident that, as the shaft G rotates, the brushes K are also rotated about substantially vertical axes.
Each journal sleeve K is provided with an apertured lug K each of which is adapted to receive one end of a link I The opposite ends of these links are connected respectively to the upper ends of the arms J by which the horizontal brush J is suspended from th shaft I (see Figs. 2, 5, 6 and 8). It will be seen from Figs. 5 and 6 that the arrangement is such that, when the brushes K are rocked, the brush J will be rocked in the opposite direction, due to the manner of pivoting the yoke K and the arms J and the manner of connecting the said yoke and arms by the links K. The manner in which the brushes are so rocked will now be described (see Figs. 1, 5 and 6).
L denotes a shaft extending transversely of the apparatus and mounted in bearings L on the members 1 Intermediate its ends, this shaft is provided with a downwardly projecting arm L and at one end thereof with a substantially horizontal arm L The arm L is connected to the yoke K by means of a link L having one end pivotally con nected to the lower end of the said arm and its opposite end connected to a lug L on the yoke. A vertical rod M is connected at one end to the outer end of the arm L the lower end of said rod extending through a sleeve M carried by one of the arms B. A stop M is secured to the rod M and is located above the arm B when the latter is in its lowered position. As the arms 13 move upwardly from the position shown in Fig. 1 to the position shown in Fig. 2, the sleeve M will engage the stop M and lift the rod M, thereby rocking the shaft L which, through the arms L and the link L, will rock the yoke K thereby moving the brushes K toward the bottles which have been lifted by the upward movement of th arms B, and this movement of the brushes K will in turn rock the brush J toward the brushes K, the brushes then occupying the positions shown in Figs. 2 and 6. As the arms B move downwardly, a spring L connected to the housing at L and to the yoke K at L (see Figs. 3 and 8) will rock the yoke in the opposite direction, bringing it into engagement with the adjustable stop N, which'is mounted in a cross bar N extending between the members 1 the stop providing means for adj ustably limiting the separation of the brushes J 2 and K.
Reference has been made hereinbefore to the raising of the bottoms of the bottles in successive transverse series against the brush J The manner in which this is accomplished will 110w be described.
Extending downwardly from the horizontal flange of the angle member D are guides 0 through which rods 0 extend (see Figs. 4, 5 and 6). The upper ends of the rods are connected to an upper bottle lifting bar 0 and the lower ends are connected to the horizontal flange of an angle bar 0 constituting a lower bottle lifting bar. The lower bar is yieldably supported by springs 0* connected at their lower ones to eye bolts 0 carried by opposite ends of said bar while their upper ends are connected to opposite sides of the frame of the apparatus, as shown at O. Rods Rextend through the horizontal flange of the angle bar O and are surrounded at their upper portions by springs R bearing at their lower ends against the horizontal flange of the angle bar 0 and at their upper ends against stops R on their respective rods. The lower ends of the rods It extend through brackets R carried by the crosshead B and are provided with nuts R thereon below said brackets. When the cross-head is in its lowered position, the springs R are under sufiicient compression to overcome the lifting effort of the springs O. However, as the cross-head B rises, the brackets R move away from the nuts R thus relieving the compression exerted on the springs R and allowing the springs O to elevate the lower lifting bar 0 and the upper lifting bar 0 and the bottles above the latter, bringing the bottoms of the bottles into contact with the brush J (see Fig. 6). When the cross-head B is lowered, the lugs R will engage the nuts R and pull the rods R and the bar 0 downwardly to the position shown in Figs. 1, 4 and 5, thus lowering the bottles into the seats provided therefor in their carrier. The springs R function as an additional cushion in the lowering movements of the bars 0 and 0 bus serving to lower the bottles into their carrier seats without injury.
From the foregoing detailed explanation, it is believed that the general operation of the apparatus will be readily understood. The conveyor will be operated to move the same intermittently along the rails 1. lVhen the carrier has been brought below the rotating spindles F, the brushes J 2 and K will bein the separated relation shown in Figs. 1 and 5, due to the action of the spring L and the connecting links K. As the crosshead B starts to move upwardly, the cross bars E are moved so that the tongues E carried thereby will cooperate with the tongues E carried by the bars E to center the mouths of the bottles in such series above the lifting rods A. The bottles, when lifted from their seats by the rods A, will engage the rotating clamps F on the bottoms of the rods F and will be rotated thereby. As the bottles move upwardly, the sleeve M engages the stop M and rocks the shaft L to bring the brushes J and K toward each other, thereby to operate upon the sides and necks of the bottles, as shown in Fig. 2. The brushes K" are rotating about vertical axes while the brush J 2 is rotating about a horizontal axis and is also being reciprocated by means of the shaft H, crank H and the connections between the crank and the shaft I hereinbefore described. When the arms B are lowered, the bottles are lowered with them, the clamps F remaining in contact with the bottles until the latter are nearly within their seats. movement of the bottles the sleeve M will move away from the stop M and the spring L? will move the brushes J and K apart, as shown in Figs. land 5.
The conveyor is then advanced another step, bringing the series of bottles just treated beneath the brush J and the succeeding series beneath the bottle bottom clamps F". The arms B are again rocked upwardly, lifting the succeeding series of bottles into engagement with the clamps F and between the brushes J 2 and K, which are moved toward each other in the manner described hereinbefore. As the cross-head B moves upwardly, the springs O are permitted to lift the upper and lower lifting bars 0 and O in the manner described, the upper bar engaging the mouths of the bottles of the series thereabove and lifting the bottoms of the bottles into engagement with the rotating and reciprocating brush J On the downward movement of the arms B, resulting in the downward movement of the crosshead B, the two series of bottles are returned to the seats in their respective carriers.
The manner of brushing the bottles disclosed herein has been found to be extremely efficient, the sides and necks of the bottles being subjected to the action of the intermeshing brushes K which are rotatable about substantially vertical axes, and to the action of the brush J which rotates about a horizontal axis and which at the same time is reciprocated along the sides and necks of the rotating bottles. Furthermore, the brush J 2 serves to clean the bottoms of the bottles most effectively, due to its rotary and reciprocatory movements; and the construction by which the foregoing results have been obtained has proved to be extremely practical and eflicient in operation.
