When bottles are fed through a machine which applies lab'els, or strip stamps to the bottles, it is necessary, in certain stages of the, operation, to raise the bottle and; tohold the same temporarily stationary. Themain object of the invention is ,to provide simple and efficient mechanism for this purpose.
Fig. 3 shows the main endless conveyors I and 2, which are parallel to each other. These conveyors I and 2 are endless belts or chains or the like. Fig. 3 shows the top runs of these endless conveyors I and. 2, which are operated continuously andin unison at equal speeds, by any suitable mechanism; In this particular embodiment, each. endless conveyor consists of pivot-ally connected links.
The bottles rest upon the top runs of the conveyors I and 2, without any positive engagement of said bottles with said conveyors. Hence, if the bottles are. held against longitudinal movement, the conveyors I and 2 can slip freely relative to the. bottles.
Fig. 1 shows one of the sprockets 3, around whichone endof the endless conveyor 2 is led. This sprocket 3 is fixed to a turnable shaft 4 which isprovided with a pulley or sprocket, which is. driven by abelt or chain 5. The companion sprocket of the conveyor I is fixed to the same shaft 4, so that the conveyors I and 2 are driven in unison, and at. equal speeds. Fig. 3 shows the companion sprocket 3a of the endless conveyor .I. The shaft 4 is provided with a clutch member 6 which is slidably keyed to said shaft 4. Thi clutch member 6 is of standard construction and it is provided with a circumferential groove. The rollers 'I of a leveril, which is pivoted at 9 to the frame F of the machine, are located in said circumferential groove. The lever 8,is provided with an operating rod IE), so
that the clutch member 6 can be moved longitudinally towards and away from the companion The clutch member II is mounted. on the shaft 4, and the shaft 4 can turn freely relative to the clutch member II. The clutch member II is therefore turned, only when it meshes with the clutch member IS. The clutch member II is an extension of a sprocket I2, Whose hubis mounted turnably upon the shaft 4. The sprocket I2 is connected by a chain I4,
.to a companion sprocket. I5, which is fixed to a shaft. I6.- Thepitch diameter of the sprocket I5 is greater than the pitch diameter of the sprocket I2',so that the angular speed of rotation of the shaft lliyis less than the angular speed of rotation. of the shaft 4. A sprocket 2I, Whose pitch diameter is slightly greater than the pitch diameter of the sprocket I5, is fixed to the shaft IS. The pitch diameter of the sprocket 2I is less than the pitch diameter of the sprockets 3 and 3a. The supplemental endless conveyor I1 is supported at its ends by the sprockets 2I and I8. These sprockets 2| and I8 are of equal pitch diameter. The sprocket I8 is fixed to the turnable shaft I9. The supplemental endless conveyor I1 is provided with equally spaced projections 29.
In its normal position, the top run of the com veyor I1 is located centrally between the top runs of the conveyors I and 2, and the top surface of the top run of said conveyor I1 as below the common level of the top surfaces of the top runs of the conveyors I and 2, save that the projections 29 project vertically above said common level. By means of the drive previously described, the linear speed of movement of the supplemental conveyor I1 is less than the linear speed of movement of the conveyors I and 2. Hence, the spaced bottles are moved by the conveyors I and 2, until each bottle abuts a respective stop projection 20. The conveyors I and 2 then continue to move continuously and longitudinally, at a greater speed than conveyor I1. The conveyors I and 2 then slip continuously relative to each bottle, which continues to abut the respective projection 20.
The bottles are fed laterally, either by hand or by any conventional mechanism, along the horizontal chute or guide 22. The usual recessed indexing wheel 23 is provided, for indexing the bottles B, one by one, into the initial position illustrated by the right-hand bottle B of Fig. 1. In said position, the vertical axis of each bottle intersects the median line between the top runs of the conveyors I and 2. The indexing wheel 23 is fixed to a vertical shaft 24, whose bevel gear 25 meshes with a bevel gear 26 of a horizontal shaft 21. This horizontal shaft 21 is provided With a pulley or sprocket 28 which is connected by a chain or belt 29, to a pulley or sprocket 30 which is fixed to the shaft 4.
The cam shaft 34 has a sprocket 33, which is driven by chain 32, which is actuated by sprocket 3I of shaft 21. Cam 35 is fixed to said cam shaft 34. Vertical rods 36 are either integral with, or suitably connected to, a yoke 36a, which is provided with a turnable roll 31. The lower end of a tension spring 39 is fixed to the frame F of the machine. The upper end of the tension spring 39 is connected to a cross bar 49, which is suitably bolted or otherwise fixed to the vertical rods 36. The roll 31 is thus held yieldingly in contact with the periphery of the cam 35. A part of the upper run of the supplemental conveyor I1 is supported upon a vertically movable rod or plate 4I. At the respective ends thereof, the underside of this supporting rod or plate M is provided with respective pairs of laterally spaced lugs 42 and 43.
A two-armed lever 44 is pivotally connected by pins 45 to the frame F of the machine. Each arm of lever 44 is provided, at each end thereof, with a longitudinal slot, whose ends are closed. Each lug 43 is provided with a pivot pin 46, which extends through the respective longitudinal slot of the respective arm of lever 44. A lever 41 is pivotally connected by a pin or pins 48 to the frame F. A part of said lever 41 is located intermediate the arms of lever 44. The lugs 42 are provided with pivot pins 49, which extend through the respective slots of the arms of lever 41. The adjacent ends of levers 44 and 41 are connected by a pivot pin 50, which extends laterally through the longitudinally overlapping respective slots of said levers 44 and 41. This pin 50 is fixed rigidly to or it is turnably connected to, the upper ends of the rods 36, so that pin 50 is moved up and down in unison with rods 36. The end-slots of levers 44 and 41 permit the easy turniig of said levers to the position shown in Fig.
Referrin to Fig. 1, the cam is turned continuously in the counter-clockwise direction. This cam has a continuous cylindrical periphery, save for its recess R. When the roll 31 enters the recess R of the cam 35, the rods 36 Will be lowered, thus turning the levers 44 and 41 to the re- 'spective positions shown in Fig. 2, thus raising the plate 4|, and raising the upper run of the supplemental conveyor I1, so that the bottoms of the respective bottles B are temporarily raised above and out of contact with the top runs of the continuously operating endless conveyors I and 2.
When the movement of the conveyor I1 is stopped by separating clutch member 6 from clutch member I I, the cam shaft 34 is still turned continuously by chain 32. The longitudinal movement of the conveyor I1 is stopped when the roll 31 is about to enter recess R, or shortly before roll 31 enters recess R. Hence the respective part of the upper run of the conveyor I1 is raised, as shown in Fig. 2, so that the bottles at stations S and Sa are presented to the action of the conventional mechanism (not shown) for applying labels, strip stamps, etc., or for performing any other operation. After a predetermined interval, which is regulated by the angle subtended by recess R, the bottles are lowered to the normal level shown in Fig. 1. The clutch members 6 and II are again meshed, thus actuating conveyor I1 and permitting the main conveyors I and 2 to feed the bottles longitudinally through a distance which is equal to the distance between stations S and Sa. The clutch members 6 and II are again separated. Hence, in the first embodiment, each bottle is fed longitudinally in a series of intermittent longitudinal movements, each longitudinal movement being equal to a predetermined distance, namely, the distance between the stations. This distance is equal to the distance between adjacent members 20. If there are more than two stations, said stations are equally spaced. Between successive longitudinal movements, each bottle which is vertically aligned with a station, is raised and held 1n the raised position for a predetermined operating period, which is sufiicient for the operation of the mechanism which applies the label or strip stamp or which performs any other desired operation. At the end of said operating period, the bottle is again lowered to its normal level, and the bottle is then given its next longitudinal movement. Any conventional braking mechanism or control mechanism can be used for preventing the conveyor I1 from overrunning its predetermined longitudinal movement, when clutch members 6 and II are separated. The rod II] can be operated by hand or by any conventional automatic control.
There may be one station, or more than two stations. After the bottle has been operated upon the last station, it is moved off the top run of the conveyor I1, so that the bottle then rests wholly2 upon the top runs of the main conveyors land The dogs or projections 20 position the bottles in accurate vertical alinement with the respective station or stations. Since. the conveyorsl andfl2 haveal greater linear speed than the conveyor H, the front of each bottle abuts a. respective dog 20, before the respective bottle is. moved under the first station. As soon.ias a'bot'tleabuts the respective dog 20, the conveyors 'I and 2 slip continuously relative to the bottom wall of the bottle. The bars 15 prevent any lateral or tipping movement of the bottles B.
In the modification illustrated in Figs. 69,.the top run of the supplemental conveyor I1 is supported for longitudinalmovement upon and relative to a stationary plate This plate 5I is provided with vertically movable plungers 52, which have heads 53. Compression springs 54 normally maintain :heads. 53 in the position illustrated in Fig. 6. A lever 54a is fixed to a rock shaft '55., which is turnably supported in the frame .of the machine. A rocker arm 56 has a head which is also rigidly fixed to the rock shaft '55, so that the rocker arm 56 and'the lever 54a turnin unison with each other and with the rock shaft 55. The lever 54a is pivotally connected to an operating arm 51. Each plunger 52 is provided with a bottom head 58. When the a lever 54a is turned from the vertical position shown in Fig. 6, to the position shown in Fig. 7, the respective plunger 52 is raised, thus compressing the respective spring 54 and elevating the respective part of the top run of the supplemental conveyor I1, and thus elevating the respective bottle.
The lever 54a is then turned in the opposite direction, so as to raise the other plunger 52.
The shaft 55 is thus rocked while the longitudinal movement of'the conveyor I! is stopped.
Fig. shows the endless conveyor 2 mounted upon the sprockets 51a and 52a. The conveyor I is mounted upon a similar pair of sprockets, as
in the first embodiment, and said conveyors I and 2 are operated continuously and at constant speed, as in the preceding embodiments. The shaft 53a of the sprocket 52a is provided with a sprocket 54cm, which is connected by a chain 55a to the sprocket 56a of the drive shaft of an actuating motor 51a. The intermediate conveyor IT is mounted upon a sprocket58a and upon a smaller sprocket 59'. These sprockets 58a and 59 are respectively mounted upon the shafts 60 and GI. The shaft til is provided with a ratchet wheel 62. The shaft 53a is provided with a sprocket 63, which is connected by a chain 64 to a sprocket '65, fixed to thecam-shaft 66. The cam-shaft 66' is thus driven continuously and at constant speed. The cam 61, is fixed to said shaft 66. Cam 61 raises the rods 36 against the force of the tension spring 39, as in the first embodiment, A crank disc 10 is also fixed to the camshaft 66. A link 'II is pivotally connected at I2 to the disc 10. The link II is also pivotally connected at 12 to an arm I3 which is mounted loosely upon the shaft 60. A pawl 14 is pivoted on the pivot member 12. The rotation of the crank-disc 10 therefore reciprocates the link II and thus oscillates the arm I33, so that the shaft 60 is intermittently turned through successive angles of Supplemental pawl 14a prevents any reverse movement of shaft 60. This pawl 14a is pivoted to the frame .of the machine. The
shaft 24 of the feed wheel 23 is connected by bevel gear 16 to a corresponding bevel gear 11 on a horizontal shaft which is provided with a sprocket 13. This sprocket I8 is driven by a chain 19 from an associated sprocket on the camshaft 66. It is to be noted that whenever I refer to chainsv and sprockets, I can use other positive drive :means, "whichrprevent relative slip between the parts;
The shaft 60 and the sprocket 53a are thus turnedin-unison through an angle of 90, while the shaft and the crank-disc I0 turn through an angle of Therefore, while the camshaft 66 is turned through an angle -of18D", the intermediate conveyor.- I! is actuated so that its lugs 20 are moved longitudinally through a. distan'ce which is equal to the, distance between successive stationsof the labeling machine. :During theneXtx-rota'tionof the cam-shaftfiB through an angle of 180; the bottles B remain stationary. While the bottles B are'thuslongitudina'lly stationary, during said reverse movement of the link II, the tension spring 39 downwardly actuates the rods, thus actuating the members 44 and 41 tothe position illustrated in Fig. 2, thus said members 44 and 4! are then returned to the position shown in Fig. 1, while the intermediate conveyor I1 and its stop pins 28 are longitudinally stationary.
The shafts 53a and 66 are connected through the chain 64, by equal sprockets, so that shafts 53a and 66 and 5311 have equal angular speeds of .rotation. While the intermediate conveyor I1 is thus longitudinally stationary, the main conveyors I and 2 travel a distance which is equal to or greater than twice the distance between adjacent projections 20. The lugs 20 therefore cannot advance in front of their respective bottles, and the main conveyors I and 2 keep thebottles abutting the respective lugs 20 at all times. It would be possible temporarily to space the lugs 20 from their respective bottles, and. to operate the main conveyors at sufficient speed to restore the bottles periodically into abutment with the respective lugs 23, but this sudden stopping of the longitudinal movement of the. bottles 3- might cause them to tip over. Hence, it is. preferable to maintain each bottle which is located on the conveyor IT, continuously in contact-with a stop 20 after the initial contact has been. secured, although the invention is not limited to this.
The. shaft 24 turns 60 while the shaft 66 turns a complete revolution, because the wheel "2:3 has. six pockets and it therefore must place .linelbetween thelaterallyspaced conveyors I and 2., each pin 20 on the conveyor Il stops the longitudinal movement of the respective bottle which would otherwise be caused by conveyors I and '2, thus causing the bottle to stop intermittently while'it is located in the zone which is above and between the shafts BI and 60.
Fig. I'1;shows a rod 80 which is moved intermitterrtly up and down by a cam. This rod is connectedby means of the pivot pin ill to the adjacent slotted ends of the levers 32 and 83, which are." respectively pivoted to frame F at 84 and *85. The rods 86 and '81 are respectively pivoted at B8 and'89 to the levers 82 and 83. The rods 86 and 81' have respective heads 86a and 81a which are raised when the rod 80 is lowered, thus raising the respective aligned bottles B off the main continuously-operating conveyors I and 2. The raised positions of the bottle is indicated by Ba, in Fig. 11. A part of the upper run of conveyor I1 is slidably supported on the stationary plate lb.
Fig. 12 shows the construction of the chain conveyors I and 2 in more detail. The conveyors I and 2 are provided with plates Ia and 2a. In the top runs of conveyors I and 2, said plates slide upon the stationary guide and supporting members G. These members G are fixed to the frame F. The plates Ia and 2a are provided in each link of the respective chains I and 2.
In the embodiment of Fig. 1, a pair of directly adjacent bottles are simultaneously raised and lowered. The right-hand bottle which is shown in Fig. 1 is spaced from its respective stop-projection 20, but said bottle will be moved by the conveyors I and 2 to abut said stop-projection before said stop-projection is located above the member 4|.
In Fig. 11, the horizontal distance between adjacent stops 20, equals one-half of the horizontal distance between heads 86a and 81a. In each embodiment, the length of each longitudinal movement of conveyor II, may be equal to the distance between adjacent projections 20. Hence, in the embodiment of Fig. 11, each bottle is initially moved to a position above 810.. It is then moved to an idle intermediate position, in which the bottle is not raised. It is then moved to the next active position, above head 86a.
In the embodiment of Fig. 10, three adjacent bottles are simultaneously raised and lowered, so that the machine of this embodiment may have three stations.
In the embodiment of Fig. 7, each longitudinal movement of the supplemental conveyor I1 is equal to the distance between heads 53. The arm 54a is first rocked counterclockwise from its neutral position which is shown in Fig. 6, and then clockwise from said neutral position, during each interval in which the conveyor I! is held against longitudinal movement. If desired, the distance between the adjacent projections 20 of Fig. 6 could be one-half or any aliquot part of the distance-between heads 53, and the length of movement of conveyor II can be similarly regulated.
If the machine is labeling the bottles at the rate of 60 bottles per minute, theintermediate conveyor I I is given 60 intermittent strokes per minute. If the distance between adjacent projections 20 is six inches, so that the length of each intermittent movement of conveyor I1 is six inches, the main conveyors I and 2 will be operated continuously at a speed of not less than 60 feet per minute. Since the period of each longitudinal movement of conveyor I1 is equal to the period of rest between successive longitudinal movements, in the embodiment of Fig. 10, the period of each longitudinal movement will be 0.5 second. While the intermediate conveyor I I is longitudinally stationary, the bottles which are elevated, are raised through a height of about e inch to inch, from the position B to the position Ba. While said conveyor I1 is longitudinally stationary, the bottle is held in the upper position Ba during the operating period of the mechanism at the respective station, and the bottle is then lowered to its original level. Hence the bottle is held against longitudinal movement, or against any substantial longitudinal movement, while the bottle is raised, also while the bottle is held in its elevated position, and also while the bottle is lowered to its normal level.
The conveyors I and 2 can be regarded as primary feeding means, and the intermediate conveyor II, with its lugs 20, operates as a stop unit for controlling the feed of the bottles. The control stop unit is separate from the feeding means, thus providing the necessary accuracy and sensitiveness of operation.
The invention applies to the feeding of containers of all kinds, including cans and the like.
Any suitable conventional control pawl or brake can be used in the embodiment of Fig. 10, in order to prevent the auxiliary conveyor I! from overrunning the predetermined length of each longitudinal movement thereof. It is very old and well-known to apply a brake or locking device to a machine, simultaneously with the shutting on of power thereto, in order to prevent overrunning, and to use various movements, such as the Geneva or Maltese cross, the Lumiere or harmonic cam, etc., in or to move a band or chain conveyor intermittently through an accurately predetermined distance, without overrunning. Hence, these well-known devices, which I can use, require no illustration.
For convenience, the auxiliary member Il may be designated as being stationary when it is not being longitudinally moved, even though part of the top run of the member I! may be raised or lowered during the cessation of the longitudinal movement.
The top walls of the top runs of the conveyors I, 2 and I? may be located in substantially the same horizontal plane. However, the top wall of the top run of the conveyor I I may be below the horizontal plane in which the top walls of the top runs of conveyors I and 2 are located, as long as the stops 20 extend to or above said horizontal plane. It is not necessary to support the central part of the bottle on the conveyor I'I, since the conveyors I and 2 provide sufficient support.
The invention is not limited to chain conveyors, or to moving the conveyors through a longitudinal path, since these factors depend upon the type of machine to which the invention is applied. Various machines for handling containers and other articles have turntables on which the articles are supported and moved through an arcuate path.
The frictional feeding force of the conveyors I and 2 may be designated as a yielding feeding force, since the bottles and containers or other articles can be held against action and said feeding force, by the stops.
I have shown preferred embodiments of my invention, but it is clear that numerous changes and omissions can be made without departing from its spirit.
