Description

This invention relates to an applicator device for simultaneously applying a plurality of so- called top-gripping type of carriers onto a number of articles arranged in a group. The invention is particularly suitable for applying top gripping carriers to bottles which are accommodated in a crate so that several multi-bottle packages are formed whereafter individual packages may be grasped and removed from the crate. The applicator device which comprises a reciprocal head is, but need not be, adapted to receive known top gripping carriers.
A known applicator for applying a top gripping type of paperboard carrier onto grouped bottles is disclosed in GB-A-1 427 510 in which arresting means are provided for engagement with a carrier within a locating zone of the applicator. The arresting means automatically engage and hold the carrier during application of the carrier on the bottles to be secured together and then automatically release the carrier.
The present invention utilises natural resilience of the paperboard carrier, which tends to return the carrier to its non-erected condition, to hold the carrier against an arresting lip in the applicator from which it is released during loading by being displaced by the bottle necks introduced into the carrier.
The invention provides an applicator device for applying at least one paperboard article carrier to a group of articles such as bottles which device comprises a base plate formed to provide a locating zone for each article carrier, each locating zone being adapted to receive an erected article carrier having apertured top and bottom walls interconnected by spaced side walls to form a generally tubular structure, said base plate having a plurality of spaced apertures formed in each of said locating zones for registry with like spaced apertures formed in the top and base walls of said carrier and arresting means carried by said base plate in each of said locating zones for engagement with the carrier adjacent one of the carrier side walls (known from GB-A-1427510), characterised in that a side wall of each locating zone of the applicator has a downwardly and outwardly inclined face which terminates remote from said base plate in an inwardly directed lip providing said arresting means so that the natural resilience of said carrier, which tends to return the carrier into its non-erected condition, cause the base wall of the carrier to be arrested by the arresting lip and the loading action of the articles into the carrier displaces the carrier longitudinally of the applicator into a more upright position, thereby releasing the carrier from the arresting lip.
An applicator device embodying the invention will now be described, by way of example, with reference to the accompanying drawings, in which:-

Figure 1 is a perspective view of an applicator head shown in operative position;
Figure 2 is a partial side view of the applicator head in which a top-gripping type bottle carrier is shown loaded into one of the locating zones of the applicator head; and
Figure 3 is a partial side view of the applicator head in which bottles are shown inserted in the bottle carrier.

Referring to the drawings, the applicator head 10 comprises a base plate 12 from one surface 12a of which a series of spaced transverse walls depend. The series of walls include a first end wall 14 which has its outermost face flush with one end of the base plate 12; a first immediate wall 16 spaced from end wall 14; a second intermediate wall 18 spaced from intermediate wall 16; and a second end wall 20 spaced from intermediate wall 18 and which has its outermost face flush with the opposite end of the base plate. A longitudinal rib 22 extends centrally along surface 12a of the base plate and divides each of the transverse walls into two similar sections. The transverse walls and the longitudinal rib together define a number of carrier locating zones Z1-Z6. Thus, each locating zone is defined by a neighbouring pair of transverse walls and the longitudinal rib.
In each locating zone, the base plate is formed with four circular bottle-neck receiving apertures, e.g. apertures a,-a4 in zone Z₃, the spacing of which is chosen so as to be in registry with aligned bottle-neck receiving apertures formed in the top and base walls of a suitably sized carton when positioned for loading in that locating zone.
By way of example, the carton 'c' shown schematically in end view in locating zone Z, in FIGURE 2 comprises substantially parallel top and bottom walls 24, 26 respectively, interconnected by spaced side walls 28, 30 respectively, and central upstanding partition panel 32, thereby forming a generally tubular structure. Top wall 24 and bottom wall 26 are each formed with four bottle neck receiving apertures 'A' located in registry.
Referring now more specifically to the applicator head construction, the first transverse end wall 14 has a downwardly and outwardly inclined inner face 34 which terminates remote from surface 12a of base plate 12 in an inwardly directed arresting lip 34a. The inner face 34 also is formed with arcuate downwardly divergent recesses 36, 38 respectively, spaced for alignment with neighbouring bottle neck receiving apertures formed in the bottom panel of an adjacent bottle carrier. The arcuate recesses each provide clearance for receiving a portion of the periphery of a bottle neck when the bottle neck is inserted into an article carrier located in the locating zone.
Thus, end wall 14 provides one transverse end of locating zones Z, and Z₄ the opposite end of which is provided by face 40 of the first intermediate wall 16. Face 40 also is formed with arcuate recesses 42 and 44, respectively, which are similar to recesses 36 and 38 but which are spaced for alignment with the opposite bottle neck receiving apertures of the same adjacent bottle carrier 'C'. The opposite face 46 of the first intermediate wall 16 is of similar construction and includes arcuate recesses 48 and 50. However, face 46 terminates remote from surface 12a of base plate 12 in an arresting lip 46a for locating zones Z₂ and Z_s. The second intermediate wall 18 is of similar construction to intermediate wall 16 described above and therefore provides an arresting lip for locating zones Z₃ and 26.
The second transverse end wall 20 also includes a downwardly and outwardly inclined inner face 52 but does not carry an arresting lip. Arcuate bottle neck clearance recesses 54, 56 are formed in the inner face 52 similar to those described in relation to end wall 14.
The applicator head is mounted for vertical reciprocal movement in a carton applicator machine which is adapted to receive a loaded crate of bottles beneath applicator head when in its raised position. At the beginning of a loading cycle flat carriers are withdrawn from a hopper, erected and correctly loaded into the locating zones of the applicator head by suitable loading means. Each locating zone e.g. Zone Z, (see FIGURE 2) receives an erected carrier'c' such that the natural resilience of the paperboard carrier which tends to return the carrier into its flat (non-erected) condition causes the base wall 26 of the carrier (adjacent side wall 30) to be held arrested under the arresting lip 34a. Bottle carriers located in the other locating zones are similarly held in position and when the applicator head is fully loaded in which one bottle carrier is present in each locating zone, the applicator head is ready to execute an applicator stroke in relation to a crate of bottles therebelow. Thus, the applicator head is then moved downwards so that the bottle necks of bottles 'B' are received in the bottle neck receiving apertures of the carriers and the caps of the bottles pass into base plate apertures 'A'. During this action and with reference to carrier'C' in locating zone Z, portions of each bottle neck pass along clearance recesses 36, 38 and 42, 44 and the loading action of the bottles into the carrier displaces the carriers longitudinally in the applicator head into a more upright position thereby releasing the carrier from the arresting lip. The side walls of the carrier are disposed in a substantially vertical position. Thereafter, the applicator head is raised again for reloading, leaving each of the carriers secured to the tops of a group of bottles 'B'.
