4 Claims. 01.312431) 1. This invention relates to a label dispenser. More particularly, it relates to a dispenser for dispensing labels which are adhesively mounted on a tape. I

In .label dispensers of the character referred to, a roll of tape is provided comprising the tape proper and spaced labels mounted upon and secured to the tape by means of a pressure-sensitive adhesive. It is desirable to peel the individual labels from the tape automatically and rapidly. In accomplishing this, it is not only necessary to feed the tape i110 a'peeling mechanism, but it is also important to provide heat to facilitate the peeling action. p

It is .an object of the iinvention to provide an improved label dispenser of the character referred to. 1

vIt is a further object of the invention to provide a label dispenservof the character referred to which is capable of applying heat to the tape to facilitate peeling-of the labels therefrom, and which is also capable of rapidly peeling the labels from the tape.

It is a still further object of the invention to provide a simple, easily constructed mechanism for peeling labels from; tape and dispensing the same rapidly or. slowly as. desired, and which is simple in its operation and easy to adjust and maintain.

These and other objects of. the invention will be apparent from the ensuing description and the appended claims.

One form which the invention may assume is exemplified in the following description and illustrated by way of example in the accompanying drawings, in which:

Fig. 1 is a top plan view, partly, broken away to show certain of the interior parts, of the label dispenser-of the invention.

Fig. 2 is a vertical, longitudinal section taken along the line 22 f 1'.

Fig. 3 is a vertical section taken along the line 3-3 of Fig. 2.

Fig. 4 is a perspective view, on a smaller scale, of the dispenser. i

Fig. 5 is a perspective view of the latch member. I v

Fig. 6 is a perspective view of the compressor plate. I

Referring now to the drawings; a tape dispenser generally designated as I0 is housed in a housing H comprising a cover plate l2 and a base casting l3. Disposed within the housing is a motor l4 and speed reducer Ma and as illustra ed, a heosta i=5 s also provided. Also shown are leads [6 leading to afoot switch (not shown) and power leads I], which may be con nected to any suitable source of electrical ener y (not shown). An electric heating element l8 is also provided, being disposed in a recess 19 formed in thecover plate l2. Theelectricalcircuits of the motor I4; andof the heating element 18 are not shown as they are conventional and form no-part of this invention. The speed of the motor is is controlled by the rheostat I5. The heating element l 8ris controlled by any suitable means (not shown). As illustrated, a master or toggle switch 20 is also provided and a pilot/light 2! is provided to indicate when the power is on'and the; jpparatusism-readiness for operation. 'f

Referring now more particularly to Figs. 2 and 3 a hard rubber feed-roller 30 having a grooved periphery 30a isgprov-idedz The feed roller 30 is fixed to a shaft M which is journalled in bearing brackets 32 depending from the cover plate l'2. The feed roller 30 is driven by means of a sprocket 33 fixed to theshaft 3!,"a chain-34 and a sprocket 35 which is driven by the speed reducer Ma. A generally.ueshaped'guide'member 36 is also provided, which extends from the feed roller 30 upwardly and then downwardly for a purpose explainedhereinafter. A heating and stripping plate. '40, which advantageously formed of brass, copper or other highly heatconductive material, is provided. The stripper plate 40 is secured to a countersunk portion of the cover plate I2 so that its upper surface will beflush with the cover plate, asillustrated, and, as will be seen, the stripper plate 40 is disposed directly 'abovethe heating element IS. The forward edge of the'plate 49 is beveled at M as shown so as to form a rather blunt knife edge for peeling "labels from the tape.

A front panel 42 is also provided, being hinged- 1y supported upon'the base casting l3 by'means of a shaft 43f journalled in the base casting. The front panel 42 is of inverted L shape, as illustrated, and it comprises a front portion 44 and a top portion :45. Secured to the underside of the-top portion 45 by meansofgse'rews 4'6 is a compressor plate 41, which is slotted forwardly and rearwardly of' its mid portion to provide fingers and 5|. The fingers 50 extend to beveled edge M. As will be seen, the compressor plate 56 is bent downwardly soth'at it functions as a resilient or spring-like pressure member as and for a purpose explained hereinafter. The top portion 45 of the front panel-42 terminates in a vertical rib 52,, which is similar to a rib 10 A latch member 55 is pivotally supported upon a shaft 56 extending between and journalled in opposite sides of the front panel 42. The latch journalled in the upper part of the front panel H Meanwhile, as the tape is being unwound, it will be heated by the heating element 6 as it passes over the stripper plate 40, thus facilitating peelmember 55 comprises a handle portion 51, a front portion 58 and a guide and bracket portion 6.. A guide roller 6| is supported upon a shaft 62, the ends of which are received in ovate slots 63 formed in opposite sides of the latch member, and springs 64 are provided to urge the roller 6| to its forward position as viewed in Fig. 2. That is to say, when the latch member 55 is in the position shown in Fig. 2, the springs 64 urge the roller 6| toward the guide member 36 and the feed roller 30. Aguide member or guard 65 is also provided, extending, as illustrated, from the bottom of the bracket or guide portion 60 rearwardly and upwardly to a position just behind and adjacent the guide roller 6|. As seen in Fig. 2, it will be noted that the axis of the roller 6| is above the axis 56 of the latch with respect to the axis of feed roller 36. Thus the spring will tend to keep the roller 6| in this upper position. -However, when the latch handle 51 is raised, the roller 6| will be urged rearwardly against the tension of spring 64 and past the diametrically 'oppositepoint on the roller 36 from the pivot point 56 to a permit the roller 6| to be spaced from the guide 36 and the feed roller 30 when the tape is to be inserted Clamping members H are provided,- each such member comprising a bail-shaped handle, portion 12 and a dove-tailed foot member 13 received within and slidable in' a dove-tailed groove 14 formed in the cover plate |2. Set screws 15 are provided for clamping the clamping members H in any desired position.

As illustrated, a roll of tape 8|) having labels 8| adhesively secured thereto by a suitable pressure sensitive adhesive, is placed between the clamping member 1|, which are adjusted so as to center the tape roll 80 and to support it loosely to allow unwinding. T

In employing the device thus. described, the power leads H are plugged in and the toggle switch I9 is turned to on position which results in lighting the pilot light to indicate that the machine is in operating condition. A roll of tape 80 is mounted as described above, and the end of the roll is pulled outwardly, the front panel 42 being meanwhile in open position. A sufficient length of tape is unwound by hand and is creased under the beveled edge ll of the stripper plate 40. In so creasing'the tape, it is important that the crease be made in approximately the middle of a label.

The free end-of thetape is then pressed in"- wardly so that it lies loosely against the hard rubber roller ills-The front panel 42 is then closedand the latch handle- 51 is depressed to bring the latch member into its uppermost or latching position-with its roller 6| abutting the guide member 36, as shown in Fig. 2. The rheostat I5 is then manipulated to operate the motor l4, hence the feed roller 30, at the desired speed. The feed roller will now feed the tape upwardly between the guard member 36 and the guide roller 6|, thence downwardly, where it is ing the labels, and the compressor plate 41 will press the tape firmly against the stripper plate. As the-tape rounds the beveled edge 4| of stripper plate 40, each label will be peeled off and may be caught by handor allowed to drop into a receptacle or conveyor belt (not shown).

It is thus apparent that a label dispensing machine. has been provided which is simple and rugged in its construction, which is eflicient in its operation, and which is readily controlled and easily adjusted.

While we have'shown'the preferred form of our invention, it is to be understood that various changes may be made in its construction by those skilled in the art without departing from the spirit of the invention as defined in the appended claims. r 4

Having thus described our invention, what we claim and desire to's'ecure by Letters Patent is:
