v .21 Claims. (cm-16454) This invention relates to the label wipingmechanism of a machine for labeling bottles and other articles. v

The principal objects of w this inven'tionare 11 provide for the application of a label to an article by first bringing it into contact with the article to which it is to be applied, moving a side label placing member along thelabel on one side, moving a transverse wiper over that end of the label to lay it down on the article, moving a second sidelabel placing member in the same direction as the first one to bring the other end of the label around the article toa certain point-and finally bringing the same or another transverse wiper back to lay down the last-named 'end of thelabel, either over the first named end or in registration therewith; to provide simple and effective means for operating the several devices for carrying out the above mentioned operation; to provide means for controlling them, and to provide an improved method of wiping a label around anarticle.

Other objects and advantages of the invention will appear hereinafter. j

The invention-isshown as applied to a machine embodying'a" frame 10 and operated by a power shaffl'il' driven in any desired way. Through bevelgears 12 this shaft drives a transverse shaft 13} ha'ving a; sprocket wheel 14 thereon. This sprocket' wheel through a chain 8 drives a cam shaft-9. Qn' 'this shaft are two cams 15 and 16. Thecam 15 operatesa cam roll 17 on a lever 18 whichis'held-backagainst the cam by a spring l9 and is= connected by a link 20 with a horizontal slide 21. This slide is mounted in guides on the frame lojtheseguides including a'pair of jibs 22. A single'i'ota tion of the shaft 14 will move this slidedn the' direction of the arrow in Fig. 1 to one extreme position and back tothe other with a slight dwell 1 at the extreme position.

The slideisproVidedwith a bracket 23 carrying athree amied-lever24 which has one arm connected'with a point on the bracket by a spring 25 and has on a second arm a cam roll 26 adapted to engage'a'plate cam 2'? which is mounted in fixed pos'ition cn the frame 10. The other arm of the lever- 24carriesa wiping roll 28. The wiping roll is mounted onaninclinedaxis, if the surface to be labeled is' conical as shown, but, of course, if

this sur face is cylindrical this wiper will b mounted onavertical'axis. l I

'Thewiper is formed of soft material, such as is common -wfitli'label' wipers. as for example felt, cork, rubber; or the likeyandis' held in position by any of theusual-expdients, being supported from the top and' depending from the lever 24.

'Ihe-spring"25 holds the roll 26 in contact with the can'i27. The bracket 23, with the lever 24 and spring 25, moves backand forth. The roll 26 limits 'themotion of-the wiper 28 outwardly or backwardly toward the article to-be labeled'by engagement with the cam 27. This will be explained more fully inzccnsidering the operation of the machine.

The other cam 16 on the shaft 9 operates a lever 30 -by aroll'31 in opposition to a spring 32 and thusactuates a rod33,.which is shown as being arranged'vertically. This rod, as shown in-Figs. 6 and 'lgisi-connected by apivot pin 34 and a pivot pin 35 at right angles thereto with a link 36, which its'elf is pivoted to another link 3'7. This furnishes a universal joint and the raising of the rod 33 will raise the free end of the link 37. This 1 link-37 is fixed on a rod 38 which is supported by brackets 39 on the top of the frame 10. I This shaft 38 has fixed. to it a frame40 which has secured to it a head 41. v

The-wiping head-41 is provided with two parallel;pi vots -42 on-which are'pivotally mounted by means of brackets 43, a pair of detachable side label: placing members 44-and 45. These side membersare yieldingly held toward each other by-a spring46 connecting "them and theyare limitedin thein motion towardeachbther-by-stops 47 carried by the head 41. The action of raising the rod 33 by the cam 16 swings the head. 41 on the axis 38 from a position back out of the way of the article to be labeled through the positions shown in Figs. 6 and 7.

As the label is placed in position by means of well known mechanism, shown in the formofjpirtoted label pickers 48 and held there by the usual gripper 49, the head 41 moves far enough to bring the member 44 across the label to turn theendof the label about a quarter way around the article to be labeled and cause the end to project at right angles to the main body of the label, as shown in Fig. 3. The part of the label at the center as far as it now contacts with the bottle need not be gummed. There is a dwell on the cam 16 which controls the members 44 and 45 and while these two members are at rest or moving only slowly in the position shown in Fig. 3 therotary wiper 28 is moved across the article to smooth down the end of the label brought into position by the member 44. It was stated that the spring 25 holds the wiper 28 in such position that the roll. 26 engages the surface of the cam 27 and the surface along which the roller 26 moves at this time is a straight surface.

The wiper 28 engages the article to be labeled and may engage the member 44. These two parts do not yield as the article is, of course, held firmly in the machine at this time. Therefore the wiper 28, being forced to move to the right in Fig. 3 and coming against a stationary article, is forced to move through the dotted line position shown in that figure, the roll 26 being forced away from the cam surface. The wiper 28 is pressed by the spring 25 against the surface of the article to be labeled and passes around that surface to lay down theend of the label throughout the length of that end. As the wiper leaves contact with the article to be labeled, after performing this function, there is nothing to prevent the wiper from moving backwardly as shown in dotted lines until the roll 26 engages the slanting part of the cam and then the wiper moves inwardly again to bring the wiper back into a position ready for retractive movement thereof, as will appear.

The next step in the operation of the machine consists in the movement of the members 44 and 45 further along as shown in Figs. 4 and '7. In this case the member 44 moves without function but the member 45 brings the other end of the label around so that it is laida quarter of the way around the article to be labeled. Now, with the parts in the position shown in Fig. 4, the wiper 28 moves backwardly again and, guided by the roll 26 on the cam surface, it moves inwardly against the projecting end of the label and, controlled solely by the shape of the article being labeled, it lays that end of the label down, as shown clearly in Fig. and the labeling operation is completed.

Of course, it will be understood that the usual label magazine 50 is employed. This labeling machine is shown really as applied to a ,labeler in which the article to be labeled has a straight line motion instead of a rotary motion but the principle can be applied to either type of machine. 1

In the form shown in Figs. 11 to 15, a cam, such as the cam 15, operates a lever18 and through a link 20 reciprocates a slide 51. On this slide are two. brackets 53 adjustably mounted. Each bracket carries a vertical stud, on which studs are pivoted levers 54 and 64. Each'lever has a short varmu52 andthese arms are connectedbya spring 55. This spring normally tends to force both long arms of the lever forward so that spring-mounted rolls 56 and 66 thereon will engage the surfaces of two cams 57 and 67 with spring pressure.

The cam 57 is beneath the cam 67 and is pro- .vided with a double surface for operating the levers 54 and 64, respectively, in the same way as the cam 27 in the other form operates the lever 24. The wipers 58 are shown as in the form of two cylindrical soft-surfaced rolls, one mounted on each lever. The members 44 and 45 for laying down the'ends of the labels are used and operated as in the other case.

The operation is as follows: With the parts in the position shown in Fig. 11, the member 44 is moved forward to place the label in the position shown. The wiper 58 on the lever 64 is located at the center of the object to be labeled and the slide 51 is just starting to move to the right. Guided by the left hand end of the cam 57, the roll 56 controls the left wiper 58 to move in dotted line position as indicated in Fig. 13. The roll engages the label on the article at the side thereof and comes to the position shown in that figure where this wiper has completed the laying down of that end of the label. The further motion of the slide 51 to the right brings this wiper quickly back out of the way and it continues until the roll 56 reaches the center of the double cam 57 which is the end of the motion in that direction.

In the meantime the other wiper roll 58 has been moving in the dotted line path shown in Fig. 13, its cam roll 66 being guided to the right end of the upper cam 67. At its extreme right end it encounters a slanting siuface 59, and being conical at its upper end, is pushed down by this surface until it is in the plane of the cam 57. The spring 55, which of course always exerts its force is on both levers, now forces the cam follower roll 66 over into contact with the cam surface 57 and at the same time the slide 51 starts back. Now guided by this cam the wiper roll 58 on this arm 64 moves through a path to come into contact with the now projecting right hand end of the label which has been forced forward, meantime, by the member 45. This path is like the path pictured in Fig. for the other wiper 58 only it is in the opposite direction and on the opposite end. The end of the operation will bring the wiper 58 to the position shown in Fig. 11 but the label in that case will be wiped entirely around the article and the labeling operation completed.

All this time the cam follower roll 66 has been resting against the cam surface 5'? and at that point it comes out from under the overlying cam 6'7 and springs up so as to engage the edge of that earn to bring it back as shown. Of course, the roller56 on the other lever 54 operates in the same way but that part of the cam 6'7 is broken away in Fig. 1 for the purpose of illustrating the lower cam but the slanting surface 60 corresponding with the slanting surface 59 is shown in Fig. 12. The rollers 56 and 66 are both constructed in the same way slidably mounted on a stud 61 which is fixed on the lever 54 or 64, as the case may be. The spring '71 is located under the rollerand-the top of the roller is beveled off at the edge to form a conical surface. The head of the stud 61 engages a shoulder on the inside of the roller, as shown in Fig. 15, to limit its upward motion while the cam 67, of course, holds the roller down against the opposition of the spring after it isforceddownby'the. cam surface 59 or fillandtuntil it reaches xtheposition shown on the right sidein Fig. 11;

By this construction ashorter stroke of the slide 51 is required and less time needed to complete the operationrsowthat thelmachine, as so constructed, can be used to label some articlesnot easilylabeled by machines with onlyone roller 28. I

Itwill be seen that we have provided a complete movement for the wiper or wipers and label place we members by which they smooth down thelabel all around the article and reduce the number of motions. tofore used for this purpose is very muchsimplified. The fact that the two, label placing members move together to-perform their functions in a certain specified order without necessitating the moving of one ahead of the other isamaterial simplification. The fact that a single roll 28 can be employedin this simple manner vto first wipe down one end of the label effectively on its stroke in one direction and then wipedownthe other end by itsstroke in the other direction adds materially to the simplification of the wiping mechanism of this machine. In the second form shown the travelof the slide 21;is,much reduced by having two cam operated wipers and the machine thus adapted to label some articles not so readily accommodated by the other form.

The operation of the two, sets of members from two cams on one shaft prevents any variationin the relative operations of the two and the necessity of adjustingthem after they have once been set. The spring 46 connecting the two members together with the pivotal mounting thereof to allow the two members 44 and 45 to pass over the surface of the article to be labeledwith a little spring pressure furnishes a certainty of contact at all times.
