DESCRIPTION:
BRIEF SUMMARY
The present invention relates to an apparatus and method for mounting carrying strips on bottles.
From Norwegian patent no. 166.852 is known a carrying device for a plurality of capped bottles consisting of a foldable sheet material in the form of a rectangular plate or strip folded into a case having a quadrilateral cross-section, where in two sides of the case arranged one above the other a plurality of holes are provided for the bottle necks.
Similar carrying devices for a plurality of bottles are also known from U.S. Pat. No. 2,299,525 and Norwegian Patent 165,721, which corresponds to European Patent No. 0 460 341.
Beer and soft drinks are usually stored and transported in cases. Often, however, it is of interest to make a special sale offer on a number of bottles. These are then attached to a common carrying handle, so that the customer may take with him the quantity to which the sale applies, and the handle with the specific number of bottles then constitutes a portable unit.
Carrying plates or strips of the aforementioned type are usually mounted manually on bottles standing in cases. There is a known device for automatic application of carrying strips with space for 6 bottles in a 2.times.3 configuration. This device, however, functions according to a different principle than the apparatus in accordance with the invention. Hence, the known device is built with an entirely different construction, causing it to be disproportionately expensive. The carrying strips that may be used in the present invention are of a type which does not require gluing--a process which makes the production of the carrying strips considerably more expensive. The carrying strips to be used in the invention are thus self-locking when mounted on the bottles.
With an apparatus in accordance with the invention, the carrying strips are fitted over the bottle necks and pressed into place in one simple operation, whereas with the known device this is done in two separate operations. The known device is constructed for only a specific type of bottle in a 3.times.2 configuration.
With the exception of this one device of the aforementioned type, all mounting of carrying strips is done manually. This is a very time-consuming, difficult and expensive operation. Nor does the inventor know of any devices for automatic application of carrying strips where the bottles are placed successively in a row in carrying strips.
The principle of the present invention allows the apparatus for mounting carrying strips on bottles to have a very simple construction, making it both reasonable to procure, simple to use and capable of working with a large capacity. The apparatus is relatively small and is easy to adapt to a continuous production process.
The invention comprises an apparatus for mounting carrying strips on a plurality of bottles, which is characterized in that it comprises a cardboard blank magazine having a number of interconnected vertical rods adapted to be thrust down into perforated holes stamped out in the carrying strip, an extraction means that draws the carrying strips out of the cardboard blank magazine and transfers them to a folding device, which folding device comprises a side folder designed such that the side flaps of the carrying strip are folded up when the cardboard blank is pressed against a complementarily shaped mold, there being provided in the bottom of the side fielder a plurality of pointed members that pre-bend or pierce the holes for the bottles, and top folders that fold the top flaps around the mold, a contraction device that conducts the ready-folded carrying strips sideways into a top flap holder, a push-out device that presses the ready-folded carrying strips out of the mold and into a set of hinged carrier flaps in a pressure station, and a depressor plate that presses the carrying strips down onto the bottles.
In large capacity production, a mid-station is employed prior to the pressure station.
The contraction device comprises a means for bringing a plurality of the folded carrying strips into a position
