Abstract

The applicator includes a glue container (A), gluing wheel (D) with a liquid-penetrable outer circumferential surface, and means for conveying glue to this surface. The glue is conveyed with the aid of a helically grooved stub (B) fixed to the container (A) under the wheel (D) and surrounded by a rotating sleeve (C), as well as a wedge (E) touching the inner circumferential surface of the wheel. On rotating the sleeve (C) the glue is conveyed upwards on the stub (B) and via the wedge (E) to the circumferential surface of the gluing wheel (D).

Description

Ά hPPi applicator foj glii≤j preferably fax gluing carton blanks
The present invention relates to a wheel applicator for glue, preferably for gluing carton blanks and includes a glue container, a gluing wheel with a liquid-penetrable circumferential surface, means for conveying the glue from the container to the wheel and means in the wheel for conveying the glue to the circumference of the wheel.
With the aid of the invention, there is achieved an apparatus of the kind mentioned in the introduction which excellently achieves its goals simultaneously as it is cheap to manufacture. Essentially distinguishing for the invention is that the means in the gluing wheel for conveying the glue to its circumferential surface comprises a wedge situated inside the wheel, having its apex touching the inner circumference of the wheel, this wedge being arranged, on rotation of the wheel, to urge the glue to the outer circumference of the wheel, partly by rotation per se and partly by the pressure occurring when the glue is urged between the inner circumferential surface of the wheel and the apex of the wedge.
The invention will now be described in »more detail below with the aid of a preferred embodiment example illustrated on the accompanying drawings, where
Fig. 1 is a schematic side view, partially in section, of the applicator in accordance with the present invention.
Fig. 2 depicts the applicator of Fig. 1 from above and Fig. 3 is another side view of the applicator depicted in Fig. 1.
The inventive embodiment of the applicator depicted on the drawings comprises three main parts. The first part is a glue container A, which is kept warm by a heating element in the case of melted glue. Alternatively, the container can contain cold glue.
The second part is a means for conveying the glue from the container A to a gluing wheel D, and in the illustrated embodiment this comprises a stub B situated under the wheel D and fixed to the container A, the stub being formed with a helical groove in its circum¬ ferential surface and being surrounded by a rotatable sleeve C, which is adapted to convey glue from the container A to the upwardly situated gluing wheel D when the sleeve C is rotated. This is achieved by the sleeve C, which surrounds the fixed stub B, entraining the liquid glue as the sleeve rotates so that the glue is conveyed up to the gluing wheel D.
The third part is a gluing wheel D, which has a liquid- penetrable circumferential surface, which may comprise a rotatable ring with one or more rows of holes in its circumferential surface, or a porous ring, where the glue is urged out to the outer circumferential surface of the ring partly by rotation and partly by the pressure occurring when the glue is urged between the ring and a wedge E situated inside the wheel D, where the apex of the wedge has its bisector at approximately 90° to the tangent to the place where the apex of the wedge meets the interior circumferential surface of the wheel D. The wedge E has substantially the same height as the inner circumferential surface of the wheel D, and is pivotable about its apex such as to increase or decrease the angle between the above-mentioned tangent and one of the faces of the wedge E. The amount of glue urged out through the holes in the gluing wheel D can thus be regulated. The wedge E may be sector-shaped, or it may have any other suitable configuration. The glue is applied to a body, e.g. in the form of a carton G, by the face of the carton coming into tangential contact with the glue-coated outer circumferential surface of the wheel D. The wheel D is also equipped on its outside with a scraper H for removing superfluous glue. Driving the gluing wheel D and sleeve C can take place with the aid of such as a drive motor F.
Alternatively, the glue can be conveyed up to the gluing wheel D by having the sleeve C stationary and causing the stub B to rotate.
