' Claims priority, application Great Britain October 31, 1952 4 Claims. (Cl. 118--236) This invention relates to labelling apparatus and its main object is to provide simple and reliable means for picking off onelabel at a time from 'a stack of labels, applying gumfto it, and delivering it for'application by hand or automatically to a bottle or otherarticle.

According to' the invention the apparatus comprises meansffor carryinga stack of labels with the edge of the label to be removed engaging directly on a gum-carrying roller rotating in the direction to move off the edge away from the label at the successive lines of contact, and means for periodically effecting relative movement between the stack and the roller in a direction such that the label moves relatively to the roller transversely of the radius of the roller at the line' of contact. The plane of the label resting on the roller is preferablyat an angle of 90 degrees to the radius of the roller at the line of contact and the direction of movement approximately tangential to the roller.

The labels may be carried in a label box adapted to rest by its own weight on the roller, this being effected for example by placing the labelbox in a freely slidable manner oninclined supporting means which may be lifted slightly .when a label is required.

By means of this invention the usual additional ungummed roller or other means for removing the labels from the stack is dispensed with and the labels rest continuously on the gummed roller which does not pick off a label until requiredwhereupon a slight movement of the label about tangentially of the roller is effected until a short length of label is gummed (e. g. about one to three eighths of an inch) whereupon the label is taken off by the roller, gummed and fed to the required position. As the gummed roller may rotate continuously an accumulation of gum occurs in the apex of the angle between the label and the roller which facilitates picking off the label.

The labels are preferably held by resilient means for example by one or more rubber or like resilient bands that extend around the stackof labels and a back plate and are held off the label to be first removed with the adjacent parts of the band inclined towards a position remote from the label, as more fully describedinour co-pending British application No. 27415 of 1952. A constructional form of 'the invention will now be described by way of example with reference to the accompanying diagrammatic drawings wherein:--

Figure l is a view, mainly in section on the line 1-1,

on Figure 2, of a label feeding apparatus made in accordance with the invention;

Figure 2 is a sectional view thereof on the line 2-2 on Figure 1;

Figure 3 is a sectional view thereof on the line 3-3 on Figure 1;

Figure 4 is a perspective view of the label box; and

Figures 5 and 6 are detail views showing the. principle of the invention.

A box-like frame 10 carries spindle 11 on which end collars 13 of a brass gumming roller 12 are rotatably 2 mounted. The gumming roller which may be aboutone to two inches in diameter is disposed horizontally across the apparatus towards the upper forward part thereof. The gum roller is driven by a pulley 60 which in turn is driven by a belt (not shown) from a-pulley 61 on the spindle of a motor 62. A gum box 15 has no'rear wall but the roller serves as a rear wall and is in contact with or nearly in contact with the lower rear edge of the bottom of the box. The gum box rests on a transverse spindle 16 that is mounted in the frame 10. The gum box has side extending apertured lugs 17, 18 through which pass threaded rods 19, 20 that carry springs 21, 22 and nuts 23, 24 whereby the position of the box towards and away from the gum roller 12 can be adjusted. Just above the top edge of the gum box is a rod 25 carrying rearwardly extending spaced stripper fingers 26 that lightly rest at their rear ends on the roller and serve for stripping the gummed-labels, off the roller.

At the rear upper part of the apparatus is a horizontal rod 28 carrying the free ends of a U-shaped guidemember 29. The rod is slightly above the level of the roller axis and say six to twelve inches rearwardly thereof. The U-shaped member 29 extends forwardly and downwardly at an angle of .10 to 30 (e. g. 15) degrees to the horizontal to a position forwardly of the roller where it has its fronttransverse bar 31. One of its side limbs is connected by a link 32 to the end of one side bar of another U-shaped member 33 the front transverse limb of which carries rods 35, 36 that extend forwardly andup: wardly and carry a finger bar 37 at their front ends. The member 33 is pivoted to the frame on the spindle 16 so that depression of the finger bar 37 by the operator lifts the U-shap ed guide member 29 upwardly about 'the axis of the horizontal rod 28.

The labels 40 are placed in a label box comprising a rectangular frame 41 the side limbsof which have out wardly extending flanges 42, 43 that are placed sli dably on the side limbs of the guide member 29. The frame 1 41 carries at its upper part a downwardly and rearwardly extending slotted bar 45 which extends down the back edges of the labels. This'bar carries a bracket 46 which is adjustable along the slot for different sizes of labels. Thebetween the rear edge of the plate 47 and the bar 45.

The upper edge of the back plate is engaged under a bracket 49 attached to the frame 41. The transverse front limb-of the frame carries a row of round pins 50 extending upwardly of the frame. At least one extensible band 51 e. g. a band of rubber or other elastic material is placed around the back plate 48 and stack and is pulled off the stack at the side (front) where the first label is to be removed and held off the label by engaging on one or more of the pins 50 so that the band 5 1, is approximately triangular shape at its lowerpart whereby it grips the edges of a number of labels first to be removed at opposite sides of the stack. The gripping pressure can be adjusted by pulilng out the triangular parts so as to stretch the band and then release it so that the band tends as the parts of the band fromthe opposite edges of the stack incline towards each other as they approach the supporting means. i

The label box is placed on the U-shaped guide member in the position shown in Figure 1 and slides down it by its own weight until the upper forward edge of the label gum roller 12 as shown in Figure 5 with this label at an angle marked 65 to the adjacent radius of the roller of 90 degrees and although the gum roller is rotating with its succeeding lines of contact moving in the direction upwards 01T the edge of the label, it is in contact with such a small area of the'label that it does not overcome the retaining force of the rubber bands. Upon each depression of the finger bar 37. the stack of labels is slightly raised so that the label moves transversely to the adjacent radius of the gum roller and as shown in Figure 6 a larger area of the front label which tends to adhere to the roller is now in contact with the gum roller and a label is picked ofijgummed and delivered to the front of the apparatus on 'toa delivery plate 64 a part only of which is shown in Figure2 and which forms a closure plate for the gum box.
