Patented sept. 3, 1912.y

To all 'whom t may concern:

Be it known that I, FREDERICK GROVER, a subject of the King of Great Britain, residing at Leeds, in the county of York, England, have invented certain new and useful Improvements in lVrapping-Machines, of which the following isV a specification.A y

This invention relates to machines for automatically wrapping rectangular tablets, -such as chocolate cakes, in one or more 1nner wrappers and an outside binder or label.

The present invention has particular reference to a previously proposed' wrapping machine designed for folding a label around an already wrapped tablet. In this reviously described machine, a pile of abelsis contained in a vertical open-topped box having corner pieces against which the top label 1s normally held by means of a carrying plunger pressed up by a counterbalance weight arrangement and having a mechanically operated brake to hold the plunger at certain times in a lower position when s o placed, and a step-bystep rotating horizontal disk is providedhaving a series of through apertures formed with depend ing' side lugs which are caused to conta with a-gum roller prior to each aperture being brought to rest above the label box, provided mechanism being employed to cause the disk to then descend in the direction of its axis to bring the gummed lugs on to the top of the pile of labels and depress the same, the brake operating to hold the label plunger in its e depressed position, while the disk is then vpermitted'to rise to lift the top label from .the pile and flick its corners past the corners'of the label box, when the succeeding intermittent partial rotation of the disk carries the label to a position to receive a tablet which is subsequently delivered to folding mechanism.

The present object is to construct the labeling machine above referred to in such a 'manner as to cause the step-by-step rotating disk to take up one or more inner wrappers (hereinafter referred to as a wrapper) prior to being caused to take up a label from the label box, the arrangement being such that the wrapper and the label t0- gether are carried by the intermittently moved disk to a position to receive the tablet ready for the subsequent wrapper-folding v operation whereby 'the inclosing ofthe tablet in one or more wrappers can be performed simultaneously with the folding of a label around the said tablet. To this end, a stepby-step rotating disk is employed having a Series of through apertures formed with depending side lugs working in conjunction with a gum roller and a label box as before; and on the underside of the said disk at the ends of each through aperture arefixedv depending pins, say two .at each end, arranged outside or beyond the depending lugs so as not to interfere in any way with the label which'is to be carried by the latter. At the opposite side of the disk to that at which the tablet is fed or at` any other suitable position anddirectly beneath one of the apertures of the disk (assuming the latter to be stationary), is provided a fixedtable on to which an inner wrapper is fed say from a reel by feed rollers working in conjunction with a cutting device so as to deliver wrappers of a predetermined length.

As the step-by-step rotating disk is intermittently moved around, the depending lugs rst take Aup the adhesive from the gum roller, when on the said disk coming over the wrapper its depression at this point causes. the provided pins on its underside to pierce the said wrapper, pick it up and carry it a step forward to a position above `thelabel box, Where the disk by being again depressed causesthe gummed lugs to pick up the uppermost label from the label box, while the 'effect of the subsequent forward step or steps of the said disk is to carry the inner wrapper and also the outside label t0- gether forward to thev position to receive the tablet.

The inner wrapper carried by the pins of the step-by-step rotating disk is situated above the label'carried by the gummed lugs 0F LEEDS, ENGLAND, ASSIGNOR T0 THE FORGROVE MAQHINERY COMPANY LIMITED, 0F LEEDS, IEIIGrllaAlH).A

sov

of the said disk, the width of the wrapper being such as not to extend up to the gunimed portions of the label while the ends ofthe said wrapper extend loutward beyond the ends of the saidA label so as to subsequently constitute the end folds. On the wrapper and the label being together brought by the step-by-step rotating disk to the position-to receive the tablet, the latter is fed into position by any known convenient means. when the tablet and its Wrapper and label are delivered to folding 1 mechanism of any known or convenient con.- struction capable of folding over-the ends and sides of the wrapper and of simultaneously folding over the sides of the label; the gum having the effect of'securing the inner wrapper and the outside label in position around the tablet.

The invention will now be described with reference to the example of construction shown in the accompanying drawings, in

which corresponding numerals indicate like' parts in all the figures; wherein:-

, Figures 1 and 2 are respectively a sectional side elevation and a plan of theflabel pile of labels 3 carried upon the verticalA plunger 4, and 5 is the step-by-step rotating disk mounted on the vertical shaft 6 and having through apertures 7 formed with depending side lugs 8 adapted to make contact with the gumming-roller 9 of the gum trough 10 mounted on the bed-plate 2, while 11 is the slide by way of which the tablets after being wrapped are delivered; all the `parts enumerated being of known const-ruction.

According to the present invention depending pins 12 are iixed on the underside of the disk 5, at the ends of each of the through apertures 7, which depending pins 12 are situated outside or beyond the depending lugs 8 so as not to interferein any way with the label which is to be carried by the latter, while 4immediately beneath the disk 5 and at the side opposite to that of the tablet delivery-slide 11 is provided a fixed table 13 on to which by-means of feed rollers 14 a wrapper 15 is fed from a reel, (not shown), the wrapper beingr cut off to a predetermined length by a cutting device 16 so vas to leave the said wrapper 15 resting on the table 13 directly beneath one of the apertures 7 of the disk 5, and holes 17 are formed in the table 13 for admitting the points of the pins 12 011 the disk 5 being depressed.

In the example of construction shown in the drawings, each forwardstep of the disk -5 is made equal to a sixth portion of a single revolution. The forward movement therefore of the, disk 5 in the direction of the arrow (see Fig. 2) from A to B causes the 'depending side lugs 8 to recei-ve .adhe' sive from the gum roller 9. while the next step forward from B to C brings oneV of the apertures 7 of the disk 5 over the wrapper 15. when the depression of the disk 5 Aat this point causes the provided pins 12 on its underside to pierce the said wrapper 15 and pick it up, and the next step forward of the disk 5 from C t-o D brings the same aperture 7 over the label box 1, when the depression of the disk 5 at this point causes the gummed lugs 8 to pick up the uppermost label 3 from the label box 1, while the subsequent steps forward of the disk 5 from D to E and E to F bring the carried Wrapper 15 and label 3 to the position to receive the tablet. In this way, the wrapper 15 carried by the pins 12 of the step-by-step` rotating disk 5 is situated above the label 3 carried by the gummed lugs 8 of the said disk 5 asshown at Fig. 3; and in these relative positions the said Wrapper 15 and label 3 are brought by the disk 5 to the position F (Fig. 2) where they receive the tablet, around which they are subsequently l folded by any known or convenient folding mechanism as beforestated.
