18 Claims. (Cl. 226-88.!)

UNITED STATES PATENT OFFICE This invention relates to mechanism or apparatus for increasing the speed of the single delivery of separate articles to a container or bottle mouth to be capped or covered thereby.

Thus, the invention particularly includes means and apparatus for intermittently serving objects from multiple supply means to a common delivery chute and to an apparatus and means for selectively discharging the same.

This invention contemplates the provision of mechanism for selectively serving caps or closures to bottles or other receptacles with great rapidity and without injury to the cap or coating thereon, subsequent to the filling operation.

Moreover, the invention contemplates the provision of such apparatus wherein the entire process of selectively delivering and applying the closures to the bottles is entirely automatic.

This invention embraces the provision of mechanism of this character for selectively manipulating closures or other objects from a dual or multiple source of supply. whereby the same are subsequently and automatically fed to and through a single or common delivery device,

seriatim.

This invention further embraces the provision of a mechanism of this character in which the presence of a closure or predetermined number of closures in the common serving device will automatically temporarily prevent the delivering of additional closures from one or all of the supply means to the serving means, pending a subsequent disposition of one or more of the 3.3 closures in the serving device.

A further object is the provision of a machine of the character which is adapted and readily adjustable for use in applying closures to various' types and sizes of bottles.

40 Further objects and advantages are within the scope of this invention such as relate to the arrangement, operation and function of the related elements of the structure, to various details of construction and to combinations of parts, elements per se, and to economics of manufacture 55 outline;

I have illustrated one form of my invention particularly adapted for use in serving or applying skirted caps or closures which may be 01 paper, fibre. transparent cellulose material or other suitable material for milk bottles or other containers, but it is to be understood that my invention is susceptible of use with any mechanism where it is desired to selectively or periodically deliver one or more objects for various other purposes, and that the embodiment herein shown and described is illustrative only of one use to which my invention may be employed.

Referring to the drawings in detail, my invention is preferably constructed as an adjustable unit and comprises a pedestal ll) secured to a vertically moving cylindrical member or post II which is the support for the complete structure,

The post I I is slidable vertically in a tubular supporting pillar l2 and held in place by means of locking bolt l3. This adjustment is particularly desirable for rendering the machine adaptable for use in capping containers of various heights.

Mounted upon an arm I4, forming an integral part of frame I5, is a motor 35 which is preferably electrically operated and furnishes the source of power to actuate mechanism to be hereinafter described. The motor 35 is provided with a shaft 3| upon which is mounted a pulley 32 adapted to be connected by means of a flexible belt 33 to drive a pulley 34, the latter being mounted on a shaft to operate a pneumatic or vacuum producing pump 35 which is used for purposes to be later explained, the pump 35 having suction and discharge pipes 35 and 31 respectively.

Mounted upon an arm I5, preferably forming an integral part of member I5, is a bracket 4| which forms a suitable support for a cap delivery or serving chute 42 and dual magazine or cap supplying chutes 43 and 44 respectively. Said magazines which are particularly illustrated in Figures I to VII inclusive are preferably channel shaped and inclined as illustrated in Figures I and XIII. The caps designated are positioned in nested formation as particularly illustrated in Figures VII and XIII, the uppermost cap in each chute being engaged by substantially cylindrical weights 45 and 45, having guiding members 41 and 45 respectively to prevent relative rotation thereof in the channels 43 and 44, these weights serving to force the caps downwardly into engagement with the cap manipulating or withdrawing mechanism to be hereinafter described.

Positioned adjacent the lower extremities of the chutes 43 and 44, and embracing the same, are common irregular shaped sleeve like members 55, shown in Figures V and VII, which support a pinrality of resilient fingers 52 fixedly secured at their upper ends by means of clamps 53 held in place by screws 54, the lower ends of the fingers flaring inwardly and having serrated extremities adapted for engagement with the lowermost caps in the channels 43 and 44. The tension or inherent flexure in the fingers 52 serves to urge them to their innermost position toward the axis of movement of the caps 5, the inward movement of the members 52 being limited by means of stop members 55 engageable with adjustable screws 55.

If it is desired to adjust the innermost limited movement of the arms 52, it is only necessary to change the relative positions of screws 55 to effect such an adjustment. Certa n of the strips or fingers 52 are of different length, as shown in Figure VII, which diflerence in length serves a very important function in the successive feeding of caps to the chute or cap server 42, as the lowermost cap of the series will be engaged by the longest of fingers 52, thus leaving the shorter fingers to engage the next succeeding cap to prevent a withdrawal of more than one cap with each operation of the cap withdrawal plunger 55.

I have provided novel and effective means for selectively and periodically withdrawing caps from the chutes 43 and 44 to be deposited in the inclined serving chute 42. This mechanism comprises a pair of reciprocable plurrgers 55 and 5|, the upper extremity of each being provided with fittings 52 and 53, which support conically shaped flexible or yielding members 54 and 55, best shown in Figure VII, said members being formed of rubber or other suitable material and utilized in a r manner to be hereinafter explained. The fittings 52 and 53 are provided with communicating bores 55 and 51 respectively. Said bores communicating with bores 55 and 59 which in turn communicate with transverse openings 15 and H which are adapted to periodically register with openings 12 and 13 in the wall of the plunger guiding means 14 and 15, as shown in Figures V and VII, the openings 12 and 13 being connected to the common suction line 35 of the pump 35 by dual connection lines.

Fixed to the plunger 5| is a transversely projecting pin or tenon 8| carrying a roller 53 which is received into an irregular shaped cam slot 55 formed in a member 81, shown in Figure VII, the latter being free to rotate on shaft 89 which is pinned at 9| to the lower plunger 93. Freely mounted on the end of shaft 89 is a crank arm 95 which is freely connected by means of tenon 91 to gear 99 which is rigidly mounted on shaft IIII by pin I53. On the opposite end of said shaft MI is rigidly mounted a timing cam I55, fixed by means of pin I51 as shown in Figure VII. The adjoining cap feeding mechanism has similar parts such as plunger 55, tenon 55, roller 52, cam slot 84, member 85, shaft 59, pin 90, lower plunger member 52, crank arm 94, tenon 96, gear 95, shaft I55, pin I52, timing cam I54 and pin I55. Gears 95 and 59, well shown in Figure IV, are driven by spur pinion gears H5 and III, rigidly mounted on shaft II2 supported in bearings H3, H4 and H5. Shaft H2 is driven through means of pulley H5 mounted on one end of said shaft, which is driven by means of flexible belt H1, and pulley IIB, said pulley mounted on shaft H9 geared with motor 35.

I have provided means whereby the feeding of caps from chutes 43 and 44 into the serving chute 42 will be interrupted when there is a predetermined number of caps in the serving chute 42, arising by reason of the fact that the number of bottles B traveling on the conveyor "C are insufficient in number to withdraw the caps fed into the chute 42, as rapidly as the mechanism can normally feed the caps to the serving chute.

To this end the reciprocating cap feeding mechanism is therefore preferably controlled by means of the number of caps in the chute 42 through the medium of pads I25 and I25 adjustably supported upon the ends of arms I21 and I25 respectively, as shown in Figure VIII, the arms being fixed to shafts I29 and I35. Shaft I29 is preferably journally supported in bearings I3I and I32, while shaft I35 is journalled in bearings I32 and I33 carried by the frame of chute 42.

Fixed to the shaft I29 is a depending arm I35 carrying at its extremity a member I31 of hardened steel, or other suitable material with a hard wearing surface, which is adapted to be intermittently or periodically engaged by the hooklike member I39 of arm I which is secured to member 81 by means such as screws I43. Intermediate the ends of lever arm I35 is a roller I45 journalled on shaft I41, the roller I45 travelling on the surface of cam member I55 on shaft I5l, as shown in Figures II and III. Tension spring I48 holds roller I45 against said cam I55. Similar parts are connected to shaft I35 such as members I35, I35, I45, I42, and roller I 5.

As illustrated in Figure VIII, when the chute 42 is filled with caps 5, causing pads I25 and I25 to be elevated, the arms I21 and I25 are raised, thus retaining both arms I35 and I35 out of the path of the hook portions I35 and Gil I40 01 members I and I42. Said arms I and I42 are normally in positions shown in Figure VIII, for they come in contact with stop members I5I and I52, well shown in Figure IV, 5 thus causing relative movement or members 35 and 31, which in turn shortens the stroke of plungers 50 and 5| respectively through means of rollers 92 and 33 in cam slots 04 and 05. By shortening the stroke of plungers 50 and III, the flexible cup members 54 and 55 are brought into contact with the lowermost cap, of each nest of caps, contained in the supply chutes 43 and 44,

but the ports 10 and H do not register with bores 12 and 13, thus a withdrawal of a cap will only 15 be accomplished when either or both of the arms I35 or I35 come in contact with their corresponding Hook-like member I39 or I40, which will rotate the corresponding cam shaped member 35 or 01 about the axis of its corresponding shaft 33 or 39, thus causing an actual lengthening of the distance between plungers 50 and 0| and their corresponding slide members 92 and 93,

which in turn lengthens the stroke of plungers 50 and 5| causing the flexible'cup members to contact with the caps in the supply chutes, permitting registration between ports 10 and II and bores 12 and 13, and producing a partial vacuum in cups 54 and 55.

As illustrated in Figure IX the chute is only partially filled with caps, there being no cap under pad I23, the upper end of the chute having the caps. This occurs when the chute is first being filled, or when the caps in the lower end of the chute have been withdrawn. In such an arrangement the pad I25 is riding on top of a cap 5, holding lever I21 in elevated position thus preventing arm I with member I31 from coming in contact with hooklike member I39 of arm I. Since the arm I has been moved into position shown, by coming in contact with pin I5I and held in such position by friction cone member I53, governed by spring I55, tension of which is controlled by knurled nut I51, said arm will cause the stroke of plunger 5i to be shortened, therefore no closures will be withdrawn from supply chute 44. However, pad I25 is lowered as shown and allows lever I23 to be lowered thus allowing lever I35 to cause member I33 to come in contact with hook-shaped member I40, which moves arm I42 and cam member 35 on the next upward movement of plunger 50, which lengthens the stroke of plunger 50, causing registration of the vacuum means, and causing caps 5 to be withdrawn from the supply chute 43. Timing cam I05 mounted on shaft IOI makes one revolution each time gear 99 makes one revolution or in other words, each time the plunger BI is reciprocated. Timing cam I04 makes one revolution each time plunger 50 is reciprocated. The shape and movement of cams I04 and I05 causes levers I21 and I28 to be raised and lowered through a suflicient distance each revolution of said cams to allow caps to pass freely beneath the pads I25 and I29 re- 65 spectively.

As illustrated in'Figure X the chute is partially exhausted of caps 5, caused by rapid withdrawal of caps from the common serving chute, one however remaining under pad I26 thus elevating the lever I28, causing lever arm I36 and member I38 to be held in lowered position and out of position to come in contact with hook-like member I40, thus allowing cam shaped member 35 to remain in the position shown, 75 causing the stroke 0i plunger 50 to remain shortened and preventing caps from being withdrawn from supply chute 43. However, no caps are beneath pad I25 which allows arm I21 to be lowered and causes lever arm I35 to be raised and member I31 to be in position to strike hooklike member I39, thus moving arm I, on the next upward movement of plunger BI. This lengthens the stroke of plunger BI and causes caps 5 to be withdrawn from supply chute 44.

From the previous description it will be noted that plungers and 5| function 180 apart in the working cycle. If plunger 50 is in the uppermost position or cap extracting position, plunger 6| will be in lowermost position and vice versa.

It will also be noted that member I25 is made with extended side walls in preference to type shown by pad I25. These extended side walls permit said pad I25 to drop to the position shown in Figure IX, holding back the caps in the upper portion of the chute. Should member I26 not be permitted to drop to said position, and caps continuing to hold pad I25 in elevated position, caps would be fed from supply hopper 44 a greater part of the time since pad I25 would be the first one always to drop to lower position due to its location at rear of discharge chute. With this arrangement and construction, caps are uniformly fed from both supply hoppers 43 and 44.

I have provided means when either of the plungers 50 and 5| are in their uppermost position of travel to cause the lowermost cap in each supply chute to adhere to the flexible members 54 and 55 so that when the plungers 50 and 5| move downwardly the caps will be carried with the same members and deposited into the common serving chute 42. To this end the passages or bores 55, 51, 52, 53, 10 and 1| communicate by means of tube 35 to suction side of pump 35, or other suitable means for producing a normally reduced pressure, 1. e., creating a partial vacuum as compared with atmospheric pressure. This vacuum or reduced pressure is communicated to bores 53 and 59 when the plungers 50 and 5| have been moved to their uppermost position in which said bores register with bores 12 and 13 which are connected with the pipe 35 whereby the pressure within the bores 55 and 51 is materially reduced and the atmospheric pressure associated upon the upper surface of the lowermost caps, in engagement with the flexible members 54 and 55, causes the caps to be gripped by the flexible members 54 and 55 so that when the latter move downwardly, the caps will be moved therewith until the lower portion of the cap skirt engages hunter-plates I50 and II, shown in Figure V and Figure XI, said plates being so designed and arranged at the upper end of the serving chute 42 to cause the caps to be tipped or inclined. At this point and position of the plungers 50 and GI, their passages 10 and 1| will register with their corresponding vent openings I52 and I53 in the walls of the members 14 and 15 so that the pressure within the openings or bores in the plungers 50 and BI and associated parts, are immediately raised to atmospheric, the equalization of pressure and the inclination of the caps automatically release the latter from engagement with the flexible members 34 and 55, thus positioning the caps within the upper end of the serving chute 42 seriatim.

The equalization of pressure within the bores in the plungers 50 and GI takes place before said plungers have moved to their lowermost position, as shown by plunger 5| in Figure VII. and out of the path of the cap deposited by either plunger upon. the respective hunter-plate.

Bunter-plate ISI is provided with holes I80, as shown in Figure XI. These holes are directly below fingers 52 and are of the same number, six in this case. As the caps which may, if desired, be provided with a coating of wax or the like, pass by these fingers, small particles of wax may drop downwardly through these holes and thus will not accumulate in the chute 42.

The mechanism for discharging the caps from the serving chute 42 and placing the same upon bottles B is particularly illustrated in Figures I and II. The walls of the extremity of the chute 42 are enlarged as at I and to the respective side walls of which are pivoted, as at I1I, winglike members or curved fingers I12 adapted to engage the neck portion of the bottles 3" as they pass under the cap applying means. These pivoted curved fingers are held in their innermost positions by means of comparatively light tension spring I13. The members I12 serve to release the caps as they are engaged by moving bottles. A leveling finger I14 is pivoted as at I15 and has a forwardly extending horizontal portion I16. The pivotal motion of member I12 is limited by means of a stop I11 engaging an upwardly projecting portion I1B of the finger member I12. The normal opening movement of members I12 may be regulated by means of adjustable stub screws I19.

Operation The bottles which have been previously filled filing machine (not shown) by means of a conveyor C traveling beneath the serving chute 42. Each successively arranged bottle is moved by the conveyor into contact with the wing-like members I12 and should the bottles upon the conveyor be slightly out of alignment with the axis of the serving chute 42, the members I12 will move so as to bring the cap into a central position with the bottle top. Further movement of the convcyor carries the bottle to a position wherein the forward upper portion or neck of the bottle engages one of the skirts or depending portions of a cap 5 causing the latter to be deposited upon the mouth of the bottle, the cap being released by the outward movement of the members I12 as the bottle moves therebetween. The horizontal portion I18 of the pad member I14 is caused to pivot counter-clockwise and presses the skirted cup 5 upon the bottle B thus completing the cap applying operation.

With particular reference to Figures I and II, the discharge of oops 5 upon bottles permits the series 0! caps in the chute 42 to slide downward- 1y until the rearmost cap of the series has passed from beneath the pad I25. When this takes place. spring I45 acts to swing arm I21 downwardly thus moving the arm I55 into the path or reciprocation of the arm I. lengthening the stroke 01' plunger II and causing a. cap to be withdrawn from the supply chute 44. Under normal operating conditions the conveyor 0 carrics bottles 3 under chute 42 at such high rate of speed that two cops are removed from chute 42 bctore the caps in the upper portion of the mute 42 begin to feed downwardly. As stated before pod I25 is the first oi the two pads I25 and I28 to drop, or lower its position. and cause the withdrawing of a cap from its respective supply rlilltt. The pods I25 and I28 are arranged such that two caps are arranged between the same, see Figure 11. There is always one extra cap in the upper part of chute 42 resting in contact with the cap upon which pad I25 is positioned, this is also shown in Figure 11. Since plunger 80 in connection with lever arm I28 and pad I25 operate ta cycle behind plunger BI and lever I21 with pad I25, approximately two and one half caps have been lowered in the chute 42 befor pad I25 is in position to be lowered. This permits lever I28 to be lowered, thus causing lever I35 to come in contact with arm I40 lengthening the stroke of plunger 60 and withdrawing a cap from the supply chute 43. Figure IX shows pad I25 lowered to this position holding back caps in the upper portion of the chute. Upon raising of said pad I26 by cam I04, two caps will slide down the chute and pad I25 will again be lowered. This cycle of operation is continuous, feeding first a cap from supply hopper 44, then one from hopper 43. This varies occasionally due to a. cap sticking in the supply hopper or inthe discharge chute or when bottles are fed at a very low rate of speed.

It is to be understood that the motor 30 is constantly actuating the vacuum producing pump 35. and the gears 98 and 99 which constantly cause a reciprocatory movement of members 92 and 93, thus the plungers I50 and GI are also reciprocated. The normal reciprocatory movement of plungers 50 and BI however being sufiicient to carry the members 54 and 55 into engagement with the caps 5 in chutes 43 and 44, but insuflicient to bring ports 10 and 1| into communication with ports 12 and 13 connected with vacuum pump 35.

The clockwise movement of arms I21 and I28, however, bring members I and I35 into ongagement with hook portions I25 and I of arms MI and I42 causing a partial rotation of com members 85 and 81 about the axis of shafts 88 and 89 respectively, to thereby cause an increased uppermost reciprocatory movement of plungers 80 and 5| to a point that members 54 and 65 are caused to engage a cap in their respective supply chutes 43 and 44, the bores 58 and 69 registering with the passages 10 and IL. the latter with bores 12 and 18 so as to create a normally reduced pressure or partial vacuum beneath the lowermost cap 5, inside members 54 and 65. Continued rotation of gears 95 and II! moves plungers 60 and BI downwardly carrying the cups engaged to the hunter-plates I50 and iii. At this position of operating cycle bores 10 and 1| register with the vent openings I52 and I62, the prgssure between members 54 and 55. and the clips 5 becomes equalized. 1. e.. brought to normal atmospheric pressure, thus effecting a release of the caps from members 54 and 55. The exhaust air from pump 25 passes down through tube 31 where the condensation of water and oil is disposed of without further use.

Simultaneously with the release of a cap at the hunter-plate. the portion of maximum diameter or cams I04-and I05 engages rollers I and I45 causing arms I21 and I25 to permit the discharge caps to pass under the pads I25 and I25 at the proper time. After the cams have moved through a. predetermined angular relationship with respect to the plungers and GI. rollers I45 and I48 are freed of engagement with cams I04 and I05 such that pads 425 and I25 carried by arms I21 and I25, will rostupon lhv cup beneath the same in said chute 42, the pads I25 and I26 being held in place under the influence of springs I48.
