BOTTLE CAPPING AND LABELING MACHINE Filed March 23, 1956 4 Sheets-Sheet 4 B 862 Rl emei" ATTORN EY Patented Oct. 26, 1937 UNITED STATES PATENT. OFFiCE 4 Claims.

This invention relates to machines for capping bottles and more particularly to milk bsorttle capping machines which, in addition to placing the cap onto the bottle, simultaneously install a ribbon under the bottle cap with the ends of the ribbon projecting from either side of the bottle neck to present a conspicuous label to identify the contents of the bottle.

The general object of my invention is to provide a capping machine adapted particularly for the sealing of milk bottles, the novel arrangement of the mechanism of which assures the continuous operation of the machine at high speeds such, for example, as capping 200 bottles per minute.

A further object of my invention is to provide a machine of the character indicated which may be readily adapted by a simple adjustment to the handling of the several standard sizes of milk bottles, such as half-pints, pints and quarts.

Another object of my invention is to provide a bottle capping machine which will readily accommodate bottles of the same capacity but varying slightly in their dimensions, the capping '25 unit of my machine being so constructed and mounted as to assure against any breakage of the bottles.

A more specific object of my invention is to provide in a machine of this character, means by which a supplementary ribbon-like label may be installed simultaneously with the capping of the bottle, the ribbon installing means being so arranged as to readily permit its disconnection so that the machine may function toinstall the usual bottle cap without the supplementary label.

The invention will be fully and comprehensively understood from a consideration of the following detailed description when read in connection with the accompanying drawings which form part of the application, with the understanding, however, that the improvement is capable of extended application and is not confined to the exact showing of the drawings nor to the precise construction described and, therefore, such changes and modifications may be made therein as do not affect the spirit of the invention nor exceed the scope thereof as expressed in the appended claims.

To facilitate a thorough understanding of the functioning of my machine in the capping and aflixing of a ribbon-like label to the bottle a general description of the operation of my machine now follows. It will be observed after a detailed description of the apparatus is had that my machine is arranged for rotary operation around a common center and comprises a series of cappingunits adapted to be revolved co-- ordinately with the revolution of the bottles to be capped, the units being operated progressively during one revolution of the machine to accomplish in one revolution the complete operation of capping the bottle and affixing the label.

Each of the mentioned capping units is provided with a paper ribbon feed mechanism by which the required amount of paper is fed in such manner as to be disposed in a projected position over the bottle to be capped prior to the capping operation. Consequently, during the functioning of the capping unit in installing the cap into the bottle the mentioned paper ribbon is engaged between the bottle cap and the recess of the bottle. At the completion of the operation the paper ribbon thus afiixed onto the bottle is severed from the paper stock and thebottle is thereafter delivered to a receiving table.

The bottles to be capped and labeled are delivered to a table or platform II) where they are disposed in upright position and urged by suitable means in the general direction of a star feeder wheel II. The feeder wheel H is mounted for horizontal rotation, being carried on a vertical shaft 12 and comprises a series of radial arms l3, the ends of which are arcuately formed to fit the periphery of the bottles to be handled. The radial disposition of the arms-l3 presents a series of pockets into each one of which a single bottle is delivered. Consequently, as the wheel I I is rotated in the direction of the arrow shown in Fig. 2, a bottle to be capped is engaged by each of the arms l3 and conveyed in an arcuatepath to be delivered to the capping machine proper.

The table ID at one side thereof is provided with a suitably shaped fence I4 by which to guide the bottles in the desired path of travel.

As aforeindicated, the capping and labeling operation of my machine is accomplished by revolving each of the bottles in the machine, the capping and labeling operation being actuated by axially raising the bottle bodily into the capping unit. To effect these motions of the bottle a turn-table I5 is provided, as shown more clearly in Figs. 2 and 4. The turn-table I5 is equipped with an annularly arranged series of platforms l6 onto each of which a bottle is delivered by means of the star wheel I I. When the complete operation has been attained the capped and labeled bottle is delivered from the machine by means of an arcuately formed rail l6a against which the capped bottles engage during their annular travel so that same are caused to be guided off the platforms l6 and the turn-table l5 to be delivered onto a suitable receiving table.

The turn-table I5 is carried and rotationally driven by a main vertical shaft l1 disposed centrally in the machine, which shaft is journaled in a base frame l8 in which frame suitable drive mechanism is arranged. The entire machine is driven by suitable means such as an electric motor operatively connected to a drive shaft IS, the latter being journalled in a bearing 20. Onto the shaft I9 is affixed a worm gear 2| which meshes with a spur gear 22, the latter being fixedly mounted on the main shaft H. The star wheel I l is rotated in synchronized relation to the rotation of the main shaft IT by means of the spur gearing 23, one gear of which is secured to a de pending portion of the shaft l2, the other gear being fixedly mounted on the main shaft H. The star wheel shaft I 2, being arranged for vertical rotation, is journaled in a bracket 24.

Below the turn-table I5 is arranged a guide frame 25 comprising 'a series of guide bearings 26 by which each of the platforms 16 are guidedin their vertical motion. The platforms 16 are each slidably mounted in suitable apertures in the turn-table l5 and are provided with a depending cylindrical apron 21 by which to assure the maintenance of this portion of the machine in a sanitary condition. A guide rod28 projects from each of the platforms I6 within the apron 21 to be journaled in the guide bearing 26." Onthe lower end of each of the guide rods'28 is mounted a roller 29. The function of the platforms l6 and their associated rods 28 and rollers 29 is to raise the bottle into the capping unit at one point during the revolution of the bottle, by which action the capping unit is actuated to accomplish the operations of capping the bottle'and affixing the ribbon label. The rollers 29 normally ride on thetop .plate of the base [8 and atthe de- -engaged to rotate the gear 39.

sired point in the cycle of operation a cam 30 is provided presenting an inclined plane over which the rollers 29 may ride to effect the desired raising of the platforms IS.

The main drive shaft ll terminates at its upper end in a threaded portion 3|, at which point the shaft I1 is slidably coupled to a tubular shaft 32, the latter being keyed to the shaft I! to permit axial movement only relative to the same. The tubular shaft 32 extends thru the top of the machine Where same is journalled in a spider frame 33 comprising a plurality of radial arms. -From each of the mentioned arms slide tubes 34 depend, the latter being arranged to telescope with vertical rods 35. The rods 35 are supported onsuitable brackets 36 extending radially from the base frame I8 and together with the rods 35 afford a'guiding structure for the upper portion of the machine. The telescoping of the rods 35 into the tubes 34 permits of adjusting the upper portion of the machine so that same may be set to suitthe particular size of bottle to be capped. Specifically, the mentioned adjustment effects the desired vertical distance betwen the bottom of the series of capping units and the turn-table IS.

The means effecting the elevation of the upper 'portion of the machine isillustrated in detail in Figs. 2 and 4 and comprises a threaded nut 31 threadedly engaged on the portion 3| of the shaft I7. bevel gear 38, the latter being in mesh with a pinion 39. The pinion 39 is fixed to a shaft 40, the inner end of which is journalled in a recess formed in the tubular shaft 32, the opposite end being journalled in a bracket 4|. The shaft 40 projects beyond the bracket 4| to provide a squared end 42 onto which a suitable tool may be In the lower end of the shaft 32 is cut an annular groove 43 in which a circular key 44 integral with the nut 31 is,

disposed,thereby retaining the shaft 32 in operable relation tothe nut 31. By rotating the gear 39 the nut 3'! is turned on the shaft ll, of which the threaded portion 3| causes the elevation or lowering of the nut 31 and the corresponding regulation of the upper portion of the machine, particularly the capping units thereof.

The general arrangement of the capping and labeling units will now be described, during which attention is directed particularly to Figs. 1, 3 and 5. Asuitable number of capping units indicated by numeral 45 are annularly arranged about the center of the machine and are supported for vertical sliding on a turret frame 46, the latter being telescope into guide tubes 5! depending from the upper portion of the turret frame 46. Suitable compression springs 52 are disposed in the tubes 5[ to urge therods downwardly, A capping plunger 53 slides within the casing 48 of the capping unit 45 and is provided with an axially extending plunger rod 54 around which a compression spring 55 is arranged. The upper end of the plunger rod 54 is slidably journalled in the upper portion of the turret frame 46. The spring 55 is arranged to urge the plunger 53 downwardly and should be somewhat stronger than the combined pressure of the springs 52 for reasons herefinafter described.

Integral with the nut 31 is formed a ing 48.

Attention is now directed to Figs; to 9, inelusive, for a detail description of the capping and label affixing units 45. The primary functions of these units, as aforeindicated, is to feed a single bottle cap from a suitable magazine into position below the capping plunger, the. relative lowering of which pushes the cap into the recess in the neck of the bottle. The mentioned bottle caps, indicated by numeral 56, are retained in a vertical stack in the tubular magazine 51, the latter being disposed adjacent the tubular casing 48 of the capping unit. The interior of the magazine 51 is of amp-1e size at its upper portion to permit the convenient placement of an adequate stack of bottle cap-s 56, which interior diminishes at the shoulder 58 toa diameter suitable to support the lower caps 56 in substantial Vertical alignment.

The lowermost bottle cap- 56 is moved into position below the capping plunger 53 by means of a reciprocating ejector plate 59 which is supported on and actuated by a reciprocating cross head 60. The blade 59 and the cross head 66 are slidably mounted on a slide frame 6|, the latter being retained on the bottom of the capping'unit 45 by a tongue 62 engaged in a' slot formed in a bracket 63 extending'from the body of the magazine 5'1. The opposite end of the slide frame 6| is removably secured to the capping unit 45 by a screw and wing nut 64, the screw being pivoted to lugs 65 integral with the slide frame 6|, the nut engaging with a flange 65a projecting from the cas- Integral with the slide frame 6| and disposed to depend from the casing 48 is arranged a guide bell 66, the function of which is to align a bottle during the raising of the latter into position' below the capping plunger 53.

The actuation of the cross head 68 and the corresponding feeding of the bottle caps 56 is ac complished by means of a bell crank lever 61 which is fulcrumed on suitable stud screws 68 affixed to the casing 48. A pin 69 extends transversely thru the center of the plunger 53 to project from each side thereof thru suitable slots 16 in the casing 48. An arm I! forming part of the lever 61 is provided with cam shoulders 12 so arranged that by the lowering of the pin 69 relative to the casing 48 the lever 61 actuates the cross head 66 to a retracted position so that the ejector blade 59 carried thereon is disposed behind the lowermost of the bottle caps 56 in the magazine 57. This motion is transmitted thru an arm 13 forming part of the bell crank lever 61 and a link 14, the latter flexibly connecting the end of the arm 73 with ears 15 formed on the cross head 60.

It is also to be noted that the capping units 45 accomplish the installation of a ribbon-like 1abel coactively with the placement of the bottle cap into the bottle. The paper stock forming the mentioned labels is fed from rolls 88 suitably supported on the top of the turret frame 46, as shown in 'Fig. 1, on spindles 8|, which spindles are provided with frictional means for retarding the free rotation of the rolls 80. The strip of paper stock extending from the rolls 88 is fed downwardly thru suitable guide-ways formed in the turret frame 46 and passes thru feed rollers 82. The support for the feed rollers 82 and their associated drive mechanism is accomplished by means of a horizontal wheel-like frame 83, shown more clearly in Fig. 3. The frame 83 comprises a hub 84 secured to the tubular shaft 32 and a series of radial arms or spokes 85, the ends of the latter being joined by a circular band 86.

Each set of feed rollers 82 comprises an upper roller 81 and alower'roller 88, the respective shafts of which are journalled in the spokes 85.

The upper roller 81 is preferably convex on its periphery, the periphery of the lower roller 88 being concave to conform to the roller 81, see Fig.

6. Preferably, I employ the upper roller 61 as the drive roller. correspondingly, the lower roller 88, being constructed of a resilient material,

acts as a contact roller to effect the secure gripping of the paper during the feeding thereof. The shaft of the roller 81 is therefore extended beyond the periphery of the band 86, at which make up the ribbon-like label is fed to a suitable length to project over the bottle to be capped, see Fig. 8, which'feeding is accomplished during one complete revolution of the machine, specifically during the arc of rotation defined by the sector of an arcuate gear rack 9! shown in Fig. 3. The gear rack 9!, with which the idler' gears 90 mesh, is suitably supported from brackets 92 extending from the vertical tubes 34 and is so oriented from the capping operating pointas to effect the feeding of the desired amount of paper previous to the actuation of the capping operation, so that just before the bottle to be capped is to be raised by the cam 30 the paper for the label is projected over the bottle, as shown in Fig. 8. To assure that the projecting portion of the paper be held in a straight projecting line, the same is caused to assume a transversely concave form by the joint effect of thefeed rollers 82.

A detail description of the simultaneous capping and labeling operations will now be had,

during which attention is directed particularly to Figs. 6 to 9, inclusive. For purposes of clarity we may assume that one of the bottles being rotated in the machine has arrived at the position where its respective lifting roller 29 is about to engage the incline 0f the cam 36. This position may be taken as the beginning of the capping and labeling operation, it being noted however that in this position the labeling paper is projected over the bottle, as shown in Fig. 8. Accordingly, it is to be observed that one of the bottle caps 56 has been fed to position below the capping plunger 53 by the previous actuation of the ejector blade 59 and the associated mechanism including the bell crank 61.

From this point the mentioned bottle rotates a predetermined angular distance, during which the respective roller 29 is riding up the cam 36 and the bottle is therefore being raised axially on its platform l6. During the raising of the bottle to be capped the rim of same comes into contact with the projected label stock and is thereafter inserted into the depending bell 66, the tapered interior of which effects an accurate centering of the bottle in relation to the capping plunger 53. To assure the unobstructed action of the label stock during the succeeding portion of the operation the rim of the bell 66 is grooved out at diametrically opposite portions forming recesses 66a of a width adequate to permit the entrance of the paper stock. As the bottle continues to rise, the casing 48 of the capping unit 45 is caused to be raised against the pressure of the springs 52, the capping plunger 53 however remaining stationary. As the raising of the casing 48 continues the bottle cap 56 disposed thereincomes in "contact with the capping plunger 53 and is thereby inserted into the recess of the bottle neck.- Coactively with this operation the ribbon label being disposed between the cap 56 and the bottle is caused to be engaged between these members as the cap 56 is completely installed in the bottle. As this operation attains completion the ribbon label is severed from the paper stock by the engagement of same with a stationaryknife 94, which knife is secured to the spoke 85 being disposed in front of the feed rollers 82. The cutting edge of the knife 94 is inclined horizontally so that the cutting of the paper stock is gradually effected to assure against the tearing of same.

To avoid breakage of the bottles during the capping operation, such as caused by the variations in the height of the bottle, the capping plunger 53 is resiliently mounted so that when a bottle of excessive height is being capped the plunger spring 55 is accordingly compressed.

The complete capping operation having been accomplished, the capped bottle is then lowered on its platform 16 as the respective roller 29 rides down the cam 30. During this lowering the capping unit 45 resumes its former low position. Accordingly, as the casing 45-is lowered the pin 69, see Fig. 6, is relatively raised since the capping plunger 53 on which the pin 69 is carried remains substantially stationary. This relative motion of the pin 69 engaging in the cammed surfaces 12 of the bell crank 61 effects the preliminary feeding of a bottle cap 56 into position below the capping plunger 53, specifically by causing the forward motion of the blade 59 which engages with the lowermost cap 56 in the magazine 51 and slides same to the mentioned position. This position of the associated capping feed mechanism is illustrated in Fig. 6, in which position the mechanism remains until the'accomplishment of the capping operation.

The continued rotation of the turn-table l5 causes the capped bottle to come into engagement With the arcuate rail Ilia bywhich the capped bottle is discharged from the machine to a suitable platform provided for this purpose.
