(Q1. 156-259) The invention is concerned with improvements in or relating to methods of labelling bottles, and apparatus therefor.
Numerous arrangements have been proposed for applying labels to bottles by machine, but in such arrangements either individual separate labels are used which are stored in bulk in storage containers or alternatively a roll of labelling material is provided from which individual labels are torn off prior to being applied to respective bottles. In each case the known arrangements used to apply the labels to the bottles have involved the use of complicated gripping devices to select each label and to bring it individually into contact with a corresponding bottle so as to cause it to adhere to said bottle, said gripping devices either being operated in a plurality of Working stages or, not being capable of continuous, automatic operation. The disadvantages of these known arrangements lie therefore not only in their dependence upon such complicated label gripping devices but also in the fact that their overall speed of operation is inadequate for them to be capable of satisfactorily fulfilling the requirements of modern high-speed production. This is particularly so in the case where the bottles to be labelled are beer bottle which in up-to-date brewery plants which handle a very great number of bottles, have to be labelled without any delay so as to avoid any hitches in the production lines.
It is a principal object of the present invention to provide a method of labelling bottles, together with apparatus therefor, by means of which the above referred to disadvantages are substantially eliminated and the labelling of said bottles may be simply yet expeditiously carried out.
Broadly speaking the present invention consists in a method of labelling bottles wherein a continuous strip of adhesive labelling material is firstly brought into contact with a series of bottles, wherein a part of said labelling material is caused to adhere to each of said bottles, and wherein the labelling material is subsequently divided along a series of lines each located between a pair of adjacent bottles.
Similarly, the invention also consists in apparatus for labelling bottles comprising means for conveying a series of bottles along a path; means for dispensing in contact with said bottles a continuously extending strip of adhesive labelling material; means for causing a part of said strip of labelling material to adhere to each of said bottles; and means for subsequently dividing said strip along a series of lines each located between a respective pair of adjacent bottles.
In greater detail the invention consists in applying a continuously extending strip of adhesive labelling material tangentially to bottles which freely stand upright at intervals on a conveyor belt which is moved with the said strip at a constant speed, the arrangement being such that when the strip impinges against said bottles, part of said strip is cemented to each of said bottles by means of resilient pressure, and division of said strip into separate portions adhering respectively to corresponding bottle is effected 'by said resilient pressure acting upon the strip after it has been applied, whereafter each separate portion, which represents a label, is rolled completely onto its corresponding bottle in one or two stages during the uniform continuous further movement of the bottles.
If the adhesive on the strip is provided at the edge of each of those portions of the strip which become the separate label portions, the rest of each label portion can be rolled on by means of a single rolling movement. However if said adhesive is, for certain reasons, provided only in the centre of each of those portions of the strip which become the label portions, then two rolling movements in opposite sense of rotation are required.
Rolling on of the label portions can be conveniently effected during the uniform continuous further movement of the bottles on the conveyor belt by causing said bottles to pivot thereon about their respective axes, so that the relative position of the bottles to each other on the conveyor belt is not changed, although the degree of pivotal movement of the bottles of course depends upon the size of the label portion to be rolled on.
The resilient pressure exerted for cementing the labels may be obtained by a pair of endless rotating belts of sponge or foam rubber (or corresponding belts of synthetic material) arranged respectively on opposite sides of the conveyor belt and adjacent to the bodies of the bottles. These belts may be moved by means of driving rollers and, supporting rollers may be provided to press said belts against the bottles, the nature of the belts themselves eusuring that resilient pressure is obtained.
The application of the strip of labelling material to the bottles requires belts which are driven with uniform speed, this speed being equal to the speed of the conveyor belt, and separation of the strip into label portions occurring by reason of expansion of the resilient belt when not compressed against the bottles.
To effect the pivotal movement of the bottles about their axes, at least one second pair of belts may be provided, one of which belts is driven at a higher speed than the conveyor belt, whereas the other belt is driven at a lower speed than the conveyor belt.
A further characteristic of the invention consists in disposing the various operating parts of the apparatus symmetrically with respect to the conveyor belt so that label portions can be ailixed simultaneously on opposite parts of the bodies of the bottles in one operation i.e. for example front and back labels.
A particularly great advantage of the invention is that it is unnecessary to use pre-gummed or pre-printed labelling material since the gumming or printing thereof may be carried out as a function of the apparatus itself, for example, prior to the application of the strips to the bottles. The same is true for the embossing of the labelling material. For this purpose a label embossing device and/or a label printing device is arranged ahead of any adhesive applying device which may be incorporated in the apparatus.
The labelling material itself may be perforated at certain intervals e.g. at intervals which correspond to the width of the labels. The intervals may alternatively be larger, namely if the material is stored folded in a manner known per se rather than rolled. If however, as is possible, a label cutting device is provided, preferably for operation prior to the adhesive applying device, this may be arranged to prepare the strips into label portions which remain connected to each other only by few, e.g. two, narrow bridges.
One embodiment of strip labelling material according to the invention provides perforated strips along the two longitudinal sides in order to make it possible to ensure that the movement of the strip from the storage roll or the like to the place of contact with the bottles is synchronous with the movement of the conveyor belt whereon the bottles are transported. These perforated strips may also be trimmed by a second cutting device included in the apparatus and located for operation preferably before or at the same time as the label glueing device.
Finally it may be mentioned that all the working parts of the apparatus may be rigidly coupled to each other to provide synchronous operation of the apparatus as a whole. I
A preferred embodiment of the invention is diagrammatically illustrated by way of example in the accompanying drawings wherein:
FIGURE 1 represents a plan view of'a bottle-labelling apparatus,
FIGURE 2 represents a plan view in enlarged scale of part of the arrangement shown in FIGURE 1 together with a further part of the apparatus, and
FIGURES 3 and 4 illustrate respectively two alternative constructions of labelling material which may be used on the apparatus shown in FIGURES l and 2.
Referring to the drawings, 1 designates a conveyor belt whereon are placed upright a series of bottles 2 arranged relatively in spaced alignment as shown and maintained in said spaced relationship by a worm device 3, the spaces between adjacent bottles being predetermined according to the width of the labels which are to be applied to said bottles. The conveyor belt 1 is moveable in the direction of the arrow X shown in FIGURE 1 and is driven at a uniform speed. Disposed on each side of the conveyor belt 1 are storage containers within each of which'is arranged a roll 4 of labelling material which is peeled 01f the parent roll in the form of a continuously extending strip 5 which is passed through printing arrangements 6 (upper half of FIGURE 1) or embossing arrangements 7 (lower half of FIGURE 1) which successively stamp on the strip passing therethrough the design required for each label. Subsequently, by means of a guiding roller 8, the strips 5 are each passed to a respective cutting device 9 which perforates the strip delivered thereto so as to leave only narrow connecting bridges joining each part of the strip having a label design printed or embossed thereon to the next adjacent part whereon is printed or embossed the next label design.
After the strips 5 have thus been preperforated, they are passed to respective guiding rollers 11 to adhesive depositing devices which apply adhesive to one side of each of the strips, whereafter said adhesive strips are fed so as tocontact the row of moving bottles 2 on the belt 1.
If it is necessary to trim the strips 5 in any way prior to feeding them on to the bottle 2, this can conveniently be effected by a trimming device located at 12, so that the strips have adhesive applied to them and are trimmed virtually at one and the same time.
The strips 5 are fed onto the bottles 2 substantially tangentially as will be evident from FIGURE 1, and are pressed respectively against opposite parts of the Walls of the bottles by pressing devices comprising respectively endless belts 13, 13 made of thick foam or sponge rub her, and driven by rollers 14 so as to move in the same direction and at the same speed as the bottles 2 on the belt 1. As shown clearly in FIGURE 1 between each of the rollers 14 of each pressing device are arranged smaller 21 diameter supporting rollers 15 which ensure that the strips 5 are properly applied to the bottles 2 passing between the belts 13 and 13'.
The efiect of these belts 13, 13 is not only to ensure that the adhesive strips are caused to adhere to the bottles 2 passing between said belts, but also to cause the strips to divide along the lines of perforation applied previously by the cutting devices 9 as explained. This happens since, as each pair of adjacent bottles has the adhesive strip pressed on to it by the belts 13, 13' the belts press towards each other onto the lines of perforation located on those portions of the strips which extend connectively between each of said pair of adjacent bottles and which portions are of course substantially parallel to the belts 13, 13'. Thus when the bottles 2 emerge fiom between the belts 13, 13', each has a complete separate portion of each of the strips 5 adhering thereto, said portions including a complete label design, in the arrangement described one such design having been printed by the printing arrangement 6 and the other design, applied to the opposite part of the body of the bottle, having been embossed by the embossing device 7.
Each of the bottles 2 with its two separate portions respectively from the two strips 5 adhering thereto is now passed between a first pair of rolling devices similar in construction to the pressing devices and comprising respectively sponge or foam rubber belts 16, 16' driven by rollers 17 between which are smaller diameter sup-' porting rollers 18. The belt 16 is driven at a higher speed than the conveyor belt 1, whilst the belt 16 is driven at a lower speed than the said conveyor belt 1, with the result that the bottles 2 are caused to pivot about the axes so that thus one side of the label portions is slowly rolled round to adhere to its respective bottle body, the difference of the driving speeds of the belts 16, 16 being chosen so that the pivoting of each bottle is just sufiicient for this rolling-on action to take place.
The bottles are now passed on the conveyor belt 1 between a second pair of rolling devices, identical to the first mentioned pair of rolling devices and comprising sponge or foam rubber belts 19, 19' driven by rollers 20 between which are smaller diameter supporting rollers 21. In this case however the driving speed of the belt 19 is lower, and that of the belt 19' greater than the driving speed of the conveyor belt 1, with the result that each of the bottles 2 is now pivotal about its axis in a direction opposite to that in which it was pivoted when passing through the belts 16 and 16' of the first pair of rolling devices. The remaining or other side of the label portions are thus rolled on to their respective bottle bodies, so that when the bottles emerge from between the said belts 19, 19', the label portions are completely adhering thereto.
It is possible to combine with the second rolling device, e.g. with the belts 19, 19, an arrangement, known per se, for attaching neck labels or neck foils so on leaving the conveyor belt 1 the bottles 2 are quite ready for dispatch without further treatment. In this case the belts 19, 19' are of greater length.
FIGURE 3 illustrates a strip 5 wherein individual label portions 5 have been perforated by the cutting device 9. The individual label portions thus being connectively joined to each other only by narrow bridges 22 as previously referred to.
An alternative label portion 5 having longitudinally extending perforated strips 23, as well as the bridges 22, is shown in FIGURE 4. Where this type of label portion is used the strips 23 are severed along the broken lines shown at 24 by means of the previously mentioned trim: ming device 12.
