<p>1502075 Labelling machine; conveying labels HOBART CORP 28 April 1976 [16 June 1975] 17351/76 Headings B8F and B8A A printed label having a pressure sensitive adhesive on one side thereof is removed from a strip of backing material by passing the strip around an edge and is transported to an applicator by a moving endless belt conveyer. In the embodiment shown in Figs. 3 and 7, blank label stock (29) from a reel (27) moves past a photo pick-up (35), Fig. 1 (not shown), which detects the gaps between the labels and determines the label position relative to a print head 37. As the stock moves between the print hammer 37 and the rotating character wheel 40, the hammer is activated to press the label stock and an ink ribbon 42 against the wheel 40. The strip 205 of backing material is then caused to pass around a sharp corner 55 with the result that the label 58 becomes partially detached therefrom. When the position shown in Fig. 7 has been reached, a solenoid 73 is actuated to move a lever 75 to a position such that a pulley 62 at the end of the lever completes the stripping operation and presses the detached label against a plate 81. The label adheres to a belt 60 passing around the pulley 62 and the belt is set in motion to transport the label to a knurled wheel 68. As the belt passes around the wheel 68, the knurled edges (92) push the label off the belt on to a shoot 21 where it is held. The package to which the label is to be applied is then pressed against the label on the shoot 21. This causes the shoot to pivot about a point 23 and actuate a switch 93 which prevents the printing of a further label until the package has been removed. In another embodiment, Fig. 9, the detached label 104 is transported to an applicator 99 by three conveyer belts 108, 110, 111, the label being held between the belts in the manner shown in Fig. 11. The label 104 is stripped from its backing material 85 on activation of a solenoid 129 which causes a pulley 116 to move downwardly.against the tension in the belt 108. At the applicator 99 the label rests on a pair of edges 101 and a nozzle 102 is moved upwardly between the edges to apply the label to the bottom of a package passing above the applicator 99 on a conveyer.</p> |
