This is a rather expensive operation as it requires the services of an operator. Also, the labels are not applied uniformly as to position, spacing and firmness of With hand application of labels difficulty is also experienced where the temperature of the article is elevated, as for example where rubber is coming from an extruding machine.
I provide a machine by which labels, and particularly rubber labels, may be applied to successive portions of an article or to successive articles in a uniform manner and without the constant attention of an operator. My apparatus is particularly useful in applying rubber labels, eitherpartially or wholly cured, to objects having a sticky or tacky surface. One or more magazines is .or are caused .to engage the article or articles to which the labels are to be applied while they are in motion. ,The relative motion of the object anda magazine causes a label to be withdrawn from .the magazine and carried along by the object. Pressure rolls are utilized for firmly securing successive labels in place. Preferably'each magazine is disposed in a vertical plane so that theforce of gravity may be utilized to keep the desired .pressure on the labels remaining in the magazine. Particular use for my machine is in ;the application of rubber labels to hose or electrical cables after the latter have been treated with a rubber coating.
The magazine utilized for discharging the la ,bels is provided with anopening facing the article ,toreceive the label and roughly corresponding to the contour of the article. The opening is provided with overhanginge'dges along its side and rearfaces 'soas to confine'the labels. Along [the forward edge, in the direction of movement "of the magazine and the article, the overhanging edge is omitted sothat the leading edge of'the label i s pressed against the 'a'rt'icle' andthereafter the rmainder of the label is engaged with the amentya'roinng momon. As the magazine and article separate the label is withdrawnfrom behind the'overhan'ging edges of the magazine and the succeeding label engages the overhanging edges preparatory to a subsequent operation.
ment of the do'gsZZ,
of the magazine showing the application of a label to an article; and
Fig. 4 is an end view of the magazine.
Referring to the drawings, one or more magazines l are mounted for periodically engaging successive portions of an article for successive articles to deposit a label. The magazine may be mounted in many ways, a satisfactory mount- .ing being ona wheel 4, the periphery of which is shaped to engage the surface of the article 2. The
periphery 5 is interrupted at the outlet or outlets of the magazine or magazines I so as to expose the open end or ends of the magazines. The wheel ,4 is preferably supported in a vertical plane by a shaft 6 which is carried by brackets I attached to a suitable base or foundation 8. By having the r wheel 4' disposed in a vertical plane the force of gravity is utilized to keep the labels in the magazine l compacted as hereinafter described. Pressure rolls 9 and ID are mounted on the base ,8 and serve to bring the article 2, here illus-' trated asa length of hose or cable having a rubber, surface, into engagement With the periphery 5 of the wheel. A pair of complementary pressure rolls H are also mounted on the base 8 for I engaging the article 2 after the application of the label for firmly pressing the label into position. Preferably the wheel 4 is rotated by fric- ..tional engagement with the article 2.
Whi le I have illustrated the mounting for the magazine inthe form of a wheel, it is to be understood that other mountings may be utilized which periodically bring the magazine into engagement with the article; Also, the invention is applicable .to many articles other than hose or rubber covered open end which faces outwardly and occupies one of thei-openings in the periphery 5 of the wheel. The exposed side 15 of the casing I2 is made a door which is supported by hinges l6 and secured by a'latoh I1. By having the side l5 inthe' form of a door the supply of labels l8 may be easily replenished without the necessity of stopping themac'hine;
The radially inner'end of the casing is provided with'a sleeve l9 through which extends a rod?!) edges of the' teetn on opposite faces of the rod. The length of" the rod. 20 is greater than the provided'with teeth 2|, which preferablyslope 'so as to provide" half steps by reason of the offset length or the casing l2"for reasons hereinafter pointed out; Spring pressed dogs 22 are mountie'd' the icasiing'fli for engaging the'teeth I 21. Stops 24 are rovided for limiting the move- A follower "25 is attached to the end of the rod 20. The follower 25 is shaped to conform to the interior of the housing l2 and to bear against the labels l8. If desired, the follower 25 may be given sufiicient weight to exert a desired compacting pressure on the labels.
The open end of the casing I2 is provided with overhanging edges 26, 21 and 28 along two sides and the rear, in the direction of movement of the magazine, of the opening. The forward or leading edge 29 is not provided with an overhanging edge so that the advancing edge 30 of the label is brought directly into engagement with the article 2. After the leading edge 30 of the label engages the article 2 the remainder of the label is brought into engagement with the article by a rolling motion. As the magazine and article separate the leading edge is carried along with the article and the remaining edges of the label are pulled out from under the overhanging edges 26, 21 and 28, whereupon the succeeding label engages the edges. The edges of the label are firmly pressed against the article by the rollers H. If the surface of the article is soft or tacky, such as a freshly extruded rubber, the engagement with the label is quite firm.
As the magazine nears the lower point of its path of travel the force of gravity operates on the follower 25 to press it downwardly against the labels IS remaining in the magazine. If a sufiicient number of labels have been withdrawn to permit the follower to move downwardly by substantially half the width of one of the teeth 2|, one of the fingers 22 will slide under one of the teeth 2| to lock the follower in the lower position. As the magazine reaches the upper part of its path of travel the follower is held in the raised position by one or both of the fingers 22 thereby holding the labels outwardly to be engaged by the article 2.
It is to be understood that the foregoing cycle of operations may be repeated for a number of times corresponding to the number of labels in the magazine. Thereafter another magazine may be brought into use. I have found that an idle magazine can be carried on the wheel 4 in an idle position by placing a piece-of metal behind the edges 26, 21 and 28. When it is desired to bring that particular magazine into use the metal is withdrawn exposing the labels. With this construction it is also possible to have different colored labels mounted in different magazines in the same machine.
While the machine may be used for applying a wide variety of labels, I have found it particularly advantageous in applying rubber labels either wholly or partially vulcanized to. rubber articles, particularly rubber articles having a sticky or tacky surface, such as hose or electrical cables leaving an extruding or tubing machine. The shape of the periphery 5 of the wheel may be varied as desired to conform to the exterior surface of a wide variety of articles. By the use of my machine the labels are applied uniformly both as to positioning and as to spacing. The machine applies labels to articles which are at elevated temperatures.
In order to replenish the magazine I the door 15 is opened, the dogs 22 are released and the rod 20 is withdrawn to its retracted position, as shown in Fig. l. A new supply of labels [8 is introduced beneath the follower 25 and the door closed, whereupon the magazine is ready for operation.
While 'I have shown and described a present preferred embodiment of apparatus for applying labels, it is to be understood that it may be otherwise embodied within the spirit of the invention and the scope of the appended claims.
Having thus described my invention, what I claim and desire to protect by Letters Patent is:
