Definitions

  • This invention relates to labeling machines, and more particularly to labeling machines of the glued picker type.
  • the labels are applied to the articles by a swinging label picker which is pivoted above the path of travel of the articles and oscillates from the articles up to a label supply.
  • a swinging label picker which is pivoted above the path of travel of the articles and oscillates from the articles up to a label supply.
  • the picker moves forwardly and upwardly from the place of label application to the label supply, it is coated with adhesive by a roller that rolls along the upper surface of the picker toward a glue supply roll with which it comes into engagement for replenishment of the adhesive.
  • the adhesive coating on the picker enables it to adhere to a label at the label supply and carry the label down therefrom on its backward swing toward an article to be labeled.
  • An applying or transfer arm then passes through the picker and clamps the label against the article.
  • the label supply has been in the form of a stack of cut labels contained in a bottom delivery label supply holder or hopper provided with stakes or guides having offset support surfaces at their bottom ends for retaining the stack of labels.
  • the picker plate is provided with cut-outs to enable it to receive the stack guides when applying adhesive to the lowermost label in the stack. This of course leaves certain unglued portions on the label which are known as picker marks and which prevent a completely satisfactory adhesion of the label to an article, an important consideration in certain types of labeling.
  • the primary purpose of this invention is to provide an improved picker type labeling machine from which has been eliminated the disadvantages of the heretofore known machines of this type.
  • One of the objects of the invention is to provide improved label picker means which will not leave picker marks on the labels applied thereby to the articles and thereby improve the adhesive application of the picker type of labeling machine.
  • Another object of the invention is to provide improved label picker means capable of supporting the label to be atfixed to an article throughout substantially its entire area during the application of adhesive thereto.
  • a further object of the invention is to provide improved label picker means capable of feeding glued labels to articles at substantially higher rates than known types of label pickers.
  • a still further object of the invention is to provide improved label picker means which obviates the necessity for label hopper equipment and which may be employed to equal advantage in applying labels fed thereto in the form of a continuous web.
  • the label picker in a labeling machine is usually composed of two plates which are spaced apart at the time of label application to allow the applying or transfer arm to pass therebetween and clamp the glued label to the article.
  • These plates may be fixed in spaced relation i.e., have no motion relative to each other so that they apply glue to the outer edges only of the label, or they may be movable relative to each other in order to spread the adhesive over the entire surface of the label.
  • the instant invention can be used to equal advantage with either the fixed plate or the movable plate type of picker.
  • FIG. 1 is a diagrammatic, perspective view showing label applying apparatus embodying the invention
  • FIG. 2 is an enlarged elevational view of the mechanism for supplying the labels to the picker
  • FIG. 3 is a vertical sectional view of the vacuum head in such label supply mechanism

Positive tension of a desired degree may be applied to the web by connecting I tension springs 19, 19 to the ends of a pin 20 extending by a control element 26 to stop the feed of the register rolls 14, the foremost label in the web will be properly located in the field of action of the apparatus at the supply station S and properly located with respect to the cutting mechanism C to be severed from the web.
  • control element 26 for each label and each of such elements is associated with a label so that it cooperates with the scanning device and the feed rolls 14, 15 to properly register such label with the cutting mechanism C and with the apparatus located at the label supply station S.
  • the control elements 26 may be in the form of holes punched in the web, or in the form of indicia printed on the web with any suitable type of ink, or may be provided on the web in any other suitable manner.
  • the construction of the scanning device 25 will be dependent on the type of control element 26 being scanned thereby.

  • the scanning device 25 On scanning a control element the scanning device 25 will send a signal through the electrical conductors 27 to an electronic power supply box 28 which on receipt of such signal causes current to be sent through the electrical conductors 29 to an electric clutch 30 associated with the drive rolls 14, 15, and through the electrical conductors 31 to an electric brake 32 also associated with such drive rolls.
  • the scanning device 25 is adjustably mounted on a transverse bracket arm 33 having a base 34 movably mounted on the screw that connects it to the partition 12 for adjustment longitudinally of the web.

  • the shaft 36 is provided with an extension 36 that is engaged by the electric brake 31 which is secured to a frame member or partition 45 of the machine.
  • the feed roll 14 will be driven through cam shaft 43, pulley 42, belt 41, pulley 40, electric clutch 30 and shaft 36, and coacts with idler feed roll 14 to draw the Web W from the supply roll 10 and to advance the foremost label thereof past the cutting mechanism C and into the field of action of the apparatus at the label supply station S.
  • a control element 26 on a subsequent label L comes into position to be sensed by the scanning device 25 a signal is sent to the power box 28 thereby actuating the electric clutch 30 to disengage roll 15 from its associated driving pulley 40, and actuating the electric brake 32 to stop the rotation of such roll 15.
  • the foremost label in the web will be correctly positioned at the supply station S and properly located to be severed from the web by the cutting mechanism C.
  • the cutting mechanism C comprises a shear type knife having a fixed upper blade and a movable lower blade 51 pivotally connected at 52 to the upper blade 50'.

As soon as that has been accomplished, the cam 60 will cause the knife blade 51 to be lowered to enable the web to advance on its next step of movement due to the action of the feed rolls 14, 15.

  • the guide members 65 and 66 are in contracted position during the feed of the web and during the operation of the cutting mechanism C so that they will serve both as guides and supports in the advancing movement of the web W and during the vacuum gripping operation, and will also support the endmost label L after it has been severed by the web cutting blades 50 and 51.
  • cam 84 causes lever 82 to drop and pull down the flexible shaft 79 and lever arm 78, thereby causing levers 76 and 74 and the pinion 73 to rotate counterclockwise about their respective axes, as viewed in FIG. 2 of the drawings.
  • This rotation of the pinion 73 causes the two rack bars 69 and 70 to move outwardly relative to the housing 71 and thereby spread the guide members 65, 66 outwardly beyond the engaged edges of the severed label L and release such label, so that it will be wholly supported by the vacuum in the suction head 90.

It will be understood that during the forward feed of the advancing end of the web W, the lower surface of the perforated plate 91 will just overlie the advancing web and cooperate with the guide members 65, 66 to guide such advancing web end. When the forward feed of the rolls 14, 15 has terminated, with the endmost label L in registry with the suction head, suction is provided in the chamber 93 of such head to cause the suction head to grip such endmost label.
