Improvements in Machinery for Applying Labels to Boxes, and
other Objects.
I, EMIL JAGENBERG, Junior, Manufacturer, of Reichstrasse, Düsseldorf, in the
German Empire, do hereby declare the nature of this invention. and in what
manner the same is to be performed. to be particularly described and ascertained
in and by the following statement:―
The present invention relates to a machine for labelling boxes, each label being by
automatic action carried forward and gummed or supplied with any suitable
adhesive material, and eventually fixed to the box, which is likewise automatically
fed along to meet it.
In the accompanying drawings:-
-
Fig. 1 is a side view of a machine embodying my invention; Figs. 2 and 3
are partial side elevations on a larger scale; Figs. 4 to 9 represent details of
construction; Figs. 10 to 13 illustrate a box in various stages of operation.
The gum or other adhesive substance is contained in a hopper d, through
which a slide 6 is conducted, so that in passing it receives a supply of gum.
The aperture through which this slide emerges is controllable by means of a
sliding door or valve d, Fig. 2. The slide 6 is caused to reciprocate by means
of a bell-crank lever 62, which receives motion from a grooved cam b'; a roller
or pin 63, wherewith the said bell-crank lever is provided for the purpose, engag-
ing in the depression or groove of such cam. Over the slide b the label recep-
tacle a is arranged; it consists of a chamber unprovided with a bottom, but
having a number of small projections a adapted to keep the labels from falling
through, Figs. 1, 7 and 8. The receptacle a is screwed to an arm a² pivoted
at a³, a lever a serving to turn it on its pivot. This lever is capable of being
connected either directly or indirectly with the said arm a², or with the recep-
tacle itself, and it may at the same time be connected with the plate resting upon
the labels, and, similarly to such plate, slightly rise from or depress the labels,
as the case may be, in performing its movements.
The lever a is set in motion by means of a rod a5, which may be made up of
several sections or lengths, if desired, and which is attached to a spring-con-
trolled lever e pivoted at e¹ and resting upon a cam e, Fig. 7, through the medium
of a pin or friction roller. As the label receptacle is pressed down upon the
slide covered with gum, the lowermost label of the pile adheres to such slide,
and remains on the same, while the remaining labels are raised. The slide,
which had been drawn back before receiving the label, now advances along
with the same. And inasmuch as the label projects beyond the slide, it pre-
sently enters the nippers 9, which, upon receiving the label, close upon and
firmly grasp it, whilst the slide goes back again, Figs. 2, 5 and 6. The nippers g
which in closing overcome the resistance of a spring g¹, are caused to close by
the rod g, lever g³ and cam 9. The label, whereof the underside had received
gum from the slide b, is now situated over the box to be labelled, which is held
up by the plate or platform t arranged upon the vertically movable slide t¹.
This slide receives motion from the cam 2 and the lever t, which is connected

page_text: with the slide t¹ by an adjustable link 3, Figs. 1, 2 and 3. The boxes to be
labelled may be conveyed to the plate t through any suitable mechanism, such
as an endless band, for example. As each box is raised by the slide carrying it,
it is inserted between two rollers h¹ arranged on resilient levers h. These firmly
press the label on to the box at the top and on the sides, whilst folding its bottom
edge round the corner of the box, see Fig./2.
The box is now raised, until it is flush with the table and situated in front
of a slide s fitted with a resilient stop s adapted to push the box on to the table;
and as this movement is accomplished, the front edge of the label, which is still
protruding, is fixed to the box, Figs. 3 and 12. As the box further advances
under the action of the slides, it comes to be placed upon the table r, so that
presently the downwardly hanging portion of the label (Fig. 12) comes in con-
tact with the edge v¹ of the table and is thus in its turn fixed to the bottom of
the box (see Figs. 3, 4, 12 and 13). The slides receives motion from an excen-
tric s³, which is connected through a rod s³ with a lever * engaging with the
slide s.
In order that the box, while the label is being pasted to it, may be firmly
pressed against the table, an adjustable roller, brush or the like is provided,
being adapted to exert the requisite pressure upon the boxes. If desired, the
lower edge of the label may be folded round the bottom corner of the box by
causing the table to move up under the box, which in that case would be
stationary.
Having now particularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed, I declare that what
I claim is:―
1. A machine for applying labels to boxes and similar objects comprising in
its construction a device for supplying labels, a receptacle (d) for adhesive
liquid, a pair of nippers (9), a vertically movable plate (t), a horizontally movable
slide (b), and a pair of spring-actuated rollers (h¹), the said slide being adapted
to pass through the adhesive receptacle, then to take up a label, to deliver it to
the nippers, and then to withdraw, while the label is held by the nipper in the
path of the ascending platform, and pressed against the sides of the box by the
said rollers, substantially as described.
2. In a labelling machine of the type specified, a movable label-receptacle a
open at the bottom and provided with a rim or projections for holding the labels,
the said receptacle being adapted to approach the slide 6 during the return
motion of the same, so that the lowest label may adhere to the slide and be
carried along by the same, substantially as described.
3. In a labelling machine of the type specified, the means for finishing and
delivering the boxes after the labels have been applied to the top and sides of
the same, and after they have passed between the pressing rollers h¹, compris-
ing a movable table adapted to receive the boxes with the aid of a slide s
having an abutments for acting on the short projecting flap or extremity of
the label, so as to fold it against the bottom of the box and fix it to the same,
while the larger flap or projecting extremity of the label is folded down by the
edge of the table and is clipped fast during the forward motion, the box being
meanwhile held down by a brush or similar device, substantially as described.
4. A machine for applying labels to boxes and other objects, constructed and
adapted to operate substantially as described.
