15 Claims.

This invention relates to apparatus for applying labels to cylindrical articles, including pipes and electrical conduit. The invention applies more particularly to apparatus for severing labels from a strip and applying the separate labels by adhesive to the outside surface of the article.

One object of the invention is to provide improved apparatus that makes the cutting, applying and smoothing of adhesive labels on cylindrical articles entirely automatic, the articles being supplied to conveyors which carry them through the labeling machine and then discharge the labeled articles from the other end of the machine.

One feature of the invention relates to the apparatus for cutting the labels from a strip and applying the successive labels to the respective articles that are advanced to the attaching station by the conveyor. If the apparatus is to be used with thermoplastic or water-moistened adhesive, the label cutting and feeding feature is combined with apparatus for making the labels sticky as they pass beyond the cutting apparatus. Other adhesives, such as pressure-sensitive adhesives, can be used if desired.

Another object of the invention is to provide a label-attaching machine for elongated cylindrical articles with apparatus for rolling the articles, after one edge of a label is attached, in order to apply the label smoothly over its entire area. This object is obtained by means of apparatus that lifts the article part way out of the article holder of the conveyor, and that rolls the article in contact with a label smoothing surface while the article is in this elevated position.

Other objects of the invention relate to improved mechanism for coordinating the intermittent movement of a conveyor with cutting and attaching apparatus at a label attaching station, and with article rolling mechanism for wiping the label into contact with the article over the full width of the label.

The invention comprises a combination of mechanisms including gears, cams, sprocket chains and an intermittent motion device combined in such a way as to produce fully automatic cutting and applying of labels to cylindrical articles with operating parts that are simple and reliablein operation.

Other objects, features and advantages of the invention will appear or be pointed out as the description proceeds.

In the drawing, forming a part hereof, in which like reference characters indicate corresponding parts in all the views,

2 Figure 1 is a diagrammatic view showing the principal elements of the machine which is shown in detail in subsequent-figures of the drawing. Fig. 1A is a side view, partly diagrammatic and partly in section, showing a labeling machine embodying this invention.

Figs. 2a and 2b are an end view, partly broken away, of the machine shown in Fig. 1A.

Fig. 3 is a detail viewof'the spring-supported platform that lifts the articles part way out of the article holders prior to rolling.

Figure 4 is an enlarged, plan view of a portion of the machine shown in'Figure 2.

Figure 5 is a diagrammatic view showing the control mechanism for preventing operation when there is no article in position to receive a labe The machine illustrated includes'a frame assembly having vertical columns l0 and an adjustable upper frame l3 supported on the columns l0 and adjustable axially of the columns to accommodate conduits of different size. .The columns l0 extend upward from bearing plates l4 (Fig. 2), and these bearing plates also-support fixed lower frame elements comprising pedestal bearings I 5. These pedestal bearings I5support shafts l1 and [8 (Fig. 1A) on which there are ronveyor sprockets 20. I

An endless belt conveyor 2| extends between the sprockets 20 and hasv transversely extending cleats 23 with sloping faces that form shallow V depressions between the successive cleats. The surfaces of these shallow depressions comprise the article holders of the conveyonand there is a rubber insert 25 extending for the full length of each cleat, but across only an intermediate central portion of the width of each cleat in a recess 21, as shown in Fig. 2..

The shaft I8 extends beyond the pedestal hearing [5 at the right-hand side of the machine and is connected with a Geneva wheel 30' through which power is applied to the shaft I8 to produce intermittent angular movement of the shaft. A thrust washer 132 bears against the hub of the Geneva wheel 30 and against an end face of another pedestal bearing 33 which is a part of the fixed frame of the machine.

A Geneva driver and locking wheel 36 is located adjacent the Geneva wheel 30 and has a drive pin 31 extending from one side for engagement in the notches of the Geneva wheel. This driver and locking wheel 36 is pinned to a drive shaft 38 that'turns in bearings connected with the fixed frame ofthe machine. There'isa gear 40 (Fig. 1A) secured to the shaft, and this gear 3 4t meshes with a larger gear 4| on a shaft 42. Power is supplied to the shaft 42 by a sprocket chain 44 running on a sprocket 45 that is connected to the shaft 42.

The sprocket chain 44 extends around a takeup sprocket 4'! and a driving sprocket 48 on a shaft 49. A larger sprocket is also connected to the shaft 49 and this larger sprocket 5| is driven by a sprocket chain 53 from a smaller sprocket 54 on an output shaft 55 of a speed reducer 56 which is driven by a variablespeed, power driving mechanism 58 'ffiounted on top of the adjustable upper frame of the machine.

Continuous rotation of the drivin'gmechanisni 58 imparts continuous rotation to the Geneva driver and locking wheel 36, through the motion transmitting connections already described, and the pin 31 of the Geneva driver engages the notches of the Geneva wheel which have their angular spacing coordinated with the conveyor 2| so that each intermittent movement of the Geneva wheel 30-causes the conveyor 2| to move for a distance equal to thelength of one cleat. Thus when a conduit 6| islocated at the label attaching station during one period of dwell of the Geneva wheel 39, the next movement of the wheel and conveyor move the conduit 6| beyond the attaching station and bring the next successive conduit 52 into exactly the same position at the attaching station that was occupied by the conduit 8| during the preceding period of dwell.

There are two similar conveyors 2| (Fig. 2) at opposite sides of the machine, and the frame of the machine is so constructed that a conduit 6| extending across the space between the conveyors can move along thefull length of th'econveyors without encountering any obstructions. Guide plates 64 on both sides of the machine beyond theconvey'crs 21 provide limit stops for preventingaxialmovement of the conduits 6|, 62

on the conveyors. No apparatus for feeding conduits tothe conveyors or for collecting them after they are discharged from the ends of theconveyors are shown in the drawing since such handling-equipment is nota necessary part of the labeling machine and sucha showing is unnecessary for a complete'understanding of this invention. y

The region of the machine adjacent to the "conduit 6! in Fig. 14 is the attaching station of the machine. Labels are supplied to the attaching station from a ree166 supportedon a bracket 61 from the upper frame of the -machine; The labels are wrapped on the reel 66 as a continuous strip 68, and this strip 63 is fed downward across a guide roll 69 and through a paper guide 'H which includes a tension bar'i2 bearing against the top surface of the'strip 68 to maintain the strip undersome tension during the feeding operation, There are spaced feed slots in the label strip 68, preferably one feed slot for each label; and the strip of labels is fed forward, one label at a time, by a feed paw1 (4 having a stud 15 at its lower end in position to engage in the feed slot of each successive label.

The feed pawl His supported by a pivot ii at the lower end of a crank arm it. This crank armis connected to a shaft .3 0 from which a lever 82 extends, A cam roller 83 at the free end of the level 82, runs in a groove 85 of a face cam 86.

A continuous and uniform rotat-ion is transmitted to the cam 86- from the driving mechanism 58 through a sprocket 54 and sprocket-chain 69 which drive a chain sprocket 90 connected to a shaft 91, the same shaft to which the cam 86 is connected. The mechanical advantage of the motion transmitting mechanism that rotates the cam is so correlated with the driving mechanism for the Geneva driver 36 that the cam 86 makes one revolution as the Geneva driver 36 makes one. The cam track 85 is shaped to impart motion to the feed pawl i4 so as to feed the label strip 68 for a distance equal to the length of one label and in timed relation to the other mechanism of the machine.

The end of the paper guide ll is spaced from the article 6| by a distance slightly less than the length of a label so that the endmost label 92 is tangent to andextends for a moderate distance over the conduit 6! when the upper end of the label is even with the end of the paper guide II.

There is a knife blade or cutter 93 connected to a ram 94 which reciprocates through a moderate length of stroke toward and from the conduit 6|. The ram 94 has a presser foot 96 in position to come into contact with the label 92 and to push one edge of the label firmly against the outside surface of the conduit 6 l. The lower end of the presser foot 96 is preferably resilient so as to allow for manufacturing tolerances andfor some tolerance in the adjustment of the machine itself. I

The ram 94 slides in dovetailed guideways 98 connected to the adjustable upper frame of the machine. Movement of the ram M-along the guideways 98 to bring the presser foot 96 into position where it forces the label 92 against the conduit causes the cutter 93 to moveacross the label strip 68 and sever the endmost label 92 from the strip.

' a nature that requires heat to make it sticky.

The strip 68 comes through the paper guide H with the adhesive-coated side lowermost but not sticky; and there is a heater I00 located at the attaching station under a recess of the ram 94. This heater 106 is supported from the upper frame of the machine and in position to apply heat to the upper surface of the label'as the label is fed from the paper guide to labelling position above the conduit 6|. This heat is sufficient to make the'adhesive of the label-sticky as the label moves past the heater, and'the adhesive remains sticky for a substantial period of time while the conduit 6! is moved beyond the label attaching station. The heater N30 is merely representative of apparatus for activating the adhesive. 11? moistening is required, an application is placed under the label. If pressure-sensitive adhesives are used, no activators other than the ram are necessary.

The ram as has cam fcllower 32 which runs in a cam track We. formed in a cam 104 which is similar to the cam 86 and secured to the same shaft 9i so that the two cams Stand 104 turn as a unit and always remain in the same phase angle relation with one another. The cam track iii-3 shaped to give the knife '93 and pressure foot the intended sequence of movement duringeach cycle of operation of the machine. The

cam track its "is correlated with the cam track 85 so that the knife 93 severs the 1abe1rrcm the strip during a period when the feed pawl 14 is retracted and is out of the path of movement of the knife.

There is a trip lever I95 located along one side of the conveyor at the attaching station. This trip lever is movable about a pivot fulcrum I08 and the free end of the trip lever rests upon a microswitch H6. When there is a conduit 6|, 62 at the attaching station, the weight of the conduit presses the trip lever I95 downward with sufficlent force to operate the microswitch I II] in the control circuit of the mechanism that drives thecams 86 and I64.

The shaft 9| is made up of two sections in axial alignment with one another. A clutch II2 connects the two sections of the shaft 9|. The driving element of the clutch is connected with the right-hand section of they shaft (Fig. 2) and the driven section of the shaft, on which the cams 86 and I64 are carried, is connected with the driven side of the clutch I I2.

In the preferred construction, the clutch I I2 is a one-turn clutch; that is, it disengages automatically after each revolution. Such clutches, and control mechanism for them, are well known mechanical expedients and a detailed description of the clutch construction is not necessary for a complete understanding of this invention. The control of the clutch II2 by the conduits on the conveyor will be described in connection with Fig. 5.

After the conduits have passed beyond the attaching station with the label 92 attached to the conduit 6| along only one edge portion of the label, there are belts I22 for rolling the conduit 6| when it reaches the dotted line position shown in Fig. 1A. These rolling belts I22 are located near the opposite ends of the conduit so as to apply their rolling forces to the conduit without danger of shifting the conduit into oblique positions on the conveyors such as might occur if the rolling force were applied at only one end of the conduit. In the construction illustrated, there are four rolling belts I22, best shown in Fig. 2; and the rolling belts at the right hand end of the machine contact with the conduit on both sides of the surface zone to which the label- 92 is connected.

Just before the conduit 6| comes into contact with the rolling belts I22, the conduit is lifted up part way out of the conduit holders of the conveyors, that is, part way out of the V depression between the successive cleats of the conveyor. The lifting of the conduit is done by platforms I25, each having a cam face I26 that starts at a level below the bottom of the conduit and that slopes upward as illustrated in Fig. 3. The purpose of this platform is to support the conduits on a surface on which they can roll more easily, and also to hold the conduits against the rolling belt with a yielding force that is supplied by springs I21 located under the platform I25. The springs I21 and the mounting of each platform I25 will be described in connection with the explanation of Fig. 3. For the present it is sufiicient to understand that the platform I25 rests on springs that yield to provide space for the conduit 6| between the platform I25 and rolling belt I22 while at the same time maintaining the conduit pressed against the rolling belt with a predetermined pressure that depends upon the compression of the springs under the platform I25.

Each of the rolling belts I 22 (Fig. 1A) is an endless belt running on spaced rollers I36 and I31. The roller I36 is the driving roller and is secured to'a shaft I39 which is driven by a gear I46 from a larger gear I4I on a shaft I42. This shaft I42 is driven by a sprocket I44 which is rotated from the driving mechanism 56 through a chain I46, the slack of which is adjustable by an idler I41. There are preferably three sprockets 54 on the shaft 55 for driving the respective chains 53, 89 and I46. Since the sprockets 54 are all secured to the same shaft 55, it will be evident that the various mechanisms driven by the chains 53, 89 and I46 always remain in time relation with one another.

The roller I31 is supported from a shaft I49 and is an idler roller.- The lower run of the rolling belt- I22 between the rollers I36 and I 31 is provided with a plurality of idler rollers I5I for holding the belt I22 down against successive conduits 6| passing through the space between the conveyor 2| and the rolling belt I22. By preventing excessive displacement of the lower run of the rolling belt I22, the pressure of the conduit 6| againstthe platform I25 is maintained more nearly uniform.

The shafts I39 and I49, and the axles of the rollers I5I are supported from the upper frame I3 of the machine. This upper frame is adjusted by mechanism which will be described, so as to make the lower runs of the rolling belts I22 hold the conduit 6| and platforms I25 down at a level at which the conduit is in contact, preferably light contact, with the rubber insert 25. As the conduit rolls, the label 92 is wiped across the rubber insert and the entire adhesive-covered surface of the label is pressed against the surface of the conduit. The rolling belts I22 and the platforms I25 are long enough to cause several complete revolutions of the conduit, the actual number of revolutions depending upon the diameter of the conduit.

Beyond the end rollers I31 of the rolling belts I22, the platforms I25 terminate and the conveyors 2| turn downward around their sprocket 29 so that conduits on the conveyors drop off into a rack or other means provided for receiving them at the discharge end of the machine.

Fig. 3 shows the way in which each of the platforms I 25 is connected to the frame I3 of the label attaching machine. The platform I25 has a plurality .of screws I54 extending downward through bores I 56 in the frame I3. These screws I54 are threaded into the bottom of the platform I25 but the portions of the screws that extend through the bores I56 are smooth and have running clearance so that the screws are free to slide up and down in the bores. There are heads I58 at the lower ends of the screws I54. These heads are located in counterbores.

Coil springs I21 are seated in recesses in the frame I3 and extend upward into contact with the bottom of the platform I25. These coil springs are under s-ufiicient compression to force the platform, I25 upward until the screw heads: I58 strike against the ends of the counterbores.

When a conduit 6| is pressed downward against the platform I25, the springs I21 yield suflicient- 1y to provide space for the passage of the conduit 6|, and the compression of these springs causes. them to maintain an upward thrust on the platform I25 so that the conduit 6| is held against the rolling belt I22 throughout the full length of the bottom run of the belt I22.

The platform, which is preferably of metal, has a lower coefficient of friction than the rolling belt. This causes the conduit to be rolled between the surfaces of the belt and platform-in the direction of the belt travel, and as a result the direction of rolling is controlled and the eventual complete sealing of the label around the conduit is performed.

Mechanism is provided for moving the upper frame I3 on the vertical columns I to adjust the machine for articles of different size. This mechanism includes a pinion I65 (Fig. 2a) secured to a shaft I66 supported by bearings in a bracket I88 which forms a part of the adjustable upper frame I3. This pinion I95'meshes with a rack I18 on the face of an insert which is secured to one of thevertical posts or columns III. R tation of the pinion I65 causes it to move along the rack I18 and to raise or lower the upper frame I3 depending upon the direction of rotation of the pinion.

The pinion IE5 is rotated by a worm wheel I12 secured to the shaft I68 and meshing with a worm I14. This worm I14 is connected with a shaft I15 that turns in bearings in the bracket I68, and there is a hand wheel I18 for rotating the shaft I18 Whenever the adjustment of the machine is to be changed. The pitch of the worm I18is low so that the worm provides a'self-locking motion-transmitting connection between the hand wheel I18 and the rack and pinion that raise and lower the upper frame. Because of this self-locking feature, the upper frame will remain in any adjusted position until the hand 1 wheel I18 is again operated to change the adjustment.

When the invention is embodied in a machine of small size, the adjustment of the upper frame la'can be effected by applying a raising or lowering force to the frame I3 on one side only, as illustre-ted in the drawing. On machines of larger size, however, it is desirable'to provide rack and pinion mechanism, similar to the rack I18 and pinion I85, at both sides of the machine so as to move the upper frame I3 uniformly without setting up excessive stresses in the frame. When the rack and pinion mechanism is used on both sides of the machine, it may be operated from. a single hand wheel.

Adjustment of the spacing of the upper frame I3 from the lower fixed portion of the machine moves the label feeding mechanism, the label attaching ram, and the rolling belts toward or away from the conveyor. The supporting platforms I25 do not move with the upper frame, and the spacing between these platforms and the rolling belts is, therefore, increased or decreased by adjustment of the upper frame I3 to accommodate conduits of different diameter.

Fig. 5 shows the way in which the operation of the clutch H2 is controlled by the presence or absence of articles on the conveyor at the label attaching station.

The clutch II2' has a trip cam I84 and a positive stopcam I85. A trip lever I81 engages a shoulder of the cam I84 to cause the clutch to disengage. A stop lever I88 has a latch I89 at one end in position to engage in a notch I99 located in the periphery of the positive stop cam I85.

The trip lever I81 and the stop lever I88 are supported on a common pivot shaft I9I. Both levers are normally held in contact with the peripheries of their cams, the trip lever I81 by a tension spring I93 and the stop lever I88 by compression spring I94.

A plunger I96 of a'solenoid I91 is connected with the trip lever I81. Whenever the solenoid I91is energized, the plunger I96 pulls the trip lever I99 away from its-cam I84 against the tensionof the spring 1981. When the supply of electricity to the solenoid is shut off, the spring I93 pulls the trip lever I81 back into contact with the trip cam I84 so that the shoulder on the trip camwill again come into contact with the end-of the trip lever I81 as the trip cam rotates with the clutch.

There is a stud 280 extending. from one side of the trip lever across the top of the stop lever I88. Whenever the trip lever I81 is pulled down by thesolenoid I91, the stud 298 pushes the stop lever I88 downward and withdraws the latch I89 from the recess I99 of the positive stop cam I85.

The solenoid I91 is connected in the circuit with the microswitch -I ID. This switch I I8 is normally held-open by a spring and it is closed by pressure of the'trip lever --I 95 :at the label attaching' station when this trip lever has a conduit resting upon it. The presence of a conduit on the trip lever I95, therefore, closes the switch H0 and energizes the solenoid I91 so that both of'the levers I81 and I88 are moved away from their cams I88 and I85. This movement of the levers I81 and I83causes the clutch to engage and rotate through one revolution.

If another conduit is brought to the label attaching station during this revolution of the clutch II 2, the trip lever I will be again depressed, and the levers I81-and I83 will be held away from their cams at the time that the shoulder and notch of the cams come into the angular positions at which they would be engaged by the levers I81 and I88. The clutch will, therefore, make another revolution; and as long as successive conduits are brought into position to depress the trip lever I85, the clutch remains engaged and-the machine continues to operate and apply labels to successive conduits as previously described.

If there is at-any time a depression of the conveyor in which no conduit is carried, the trip lever I will remain in raised position when that depression of the conveyor reaches the label attaching-station; and the switch I II] will be open when the shoulder and notch of the cams I88 and I85 reach the angular positions for contact with the trip lever I81 and stop, lever I89, respectively. Since thesolenoid I91 is not energized when the switchv I I8 is open, the trip lever I81 and stop lever I88 cause the clutch to stop and disengage so that movement of the conveyor can continue without having the label feed and label attaching mechanisms operate.

10. A label attaching machine including a conveyor on which there are spaced holders for articles that are to be moved through the machine, a label applying station along the course of the conveyor, a label feed device at said station, common driving mechanism for the conveyor and label feed device, motion transmitting means between the common driving mechanism and'the label feed device including a cam follower that operates the label feed device, a cam for displacing the follower, and an automatic clutch that stops the cam after each operation when the follower is in position to retract the label feeding device.

11. The label attaching machine called for by claim with the cam operated by a one-turn clutch which automatically disengages after each operation of the label feeding device, and clutch control means for initiating another operation of the clutch, said control means including a trip element that is displaced by each article as it reaches the label applying station.

12. A label attaching machine comprising a conveyor with means for holding successive articles at predetermined spaced'regions along the conveyor, a label applying station along the course of the conveyor, a label feed device that moves successive labels into position for attaching them to successive articles, a ram that presses each label into contact with the corresponding article, cam means that operate the label feeding device, other cam means that operate the ram, a common shaft for both of the cam means, and a common one-turn clutch that operates the shaft in timed relation with the movement of the conveyor.

13. A label attaching machine including a conveyor with means for holding articles at spaced regions along the length of said conveyor, a platform located along the conveyor, said platform having a sloping cam surface at a region intermediate the opposite ends of the travel of the articles throughthe machine, the cam extending from a lower level upward into the path of the articles to lift the successive articles on the conveyor during a portion of their travel, and means for causing the articles to roll on the platform while thus lifted with respect to the conveyor.

14. A label attaching machine including a conveyor with means'for holding an article while both ends of the article project beyond the sides of the conveyor, guides extending parallel with the conveyor and in position to prevent transverse displacement of the articles on the conveyor, platforms extending lengthwise of the conveyor and located on both sides of the conveyor, said platforms having sloping cam surfaces at a region intermediate the, opposite ends of the travel of the articles through the machine, the cams extending from a lower level upward into the path of the articles to lift successive articles in the conveyor during a portion of their travel, and means forrolling articles along said platforms while thus lifted in the conveyor.

15. A label attaching machine including a conveyor with retaining surfaces for holding articles at spaced regionsalong the length of the conveyor as they travel toward a discharge end of the'conveyor, a platform extending along a portion of the course of the'convey-or nearer to the discharge end of the conveyor and in the path of the articles on the conveyonsaid platform comprising a sloping: surface with which successive articles come into contact and by which said articles are lifted with a camming action to remove the weight ofthe articles from the conveyor while leaving the articles still below the upper limits of said retaining surface, spring means yieldingly supporting the platform, and rolling apparatus including a moving surface located above the platform, and in contact with the articles that are raised by the platform for causing rotation of said articles as they move along the platform.
