Description

“PERFECTED LABELING DEVICE FOR SIMULTANEOUS APPLICATION OF VARIOUS SELF-ADHESIVE ARTICLES” [001] The present specification refers to an invention patent for an improved labeling device for the simultaneous application of various self-adhesive articles, belonging to the field of equipment for use in graphic arts, applied particularly in obtaining labels, tags and similar self-adhesive or others.

[002] A procedure is known, carried out in factories of self-adhesive articles or in factories of wrapping type or in sections of packaging of factories of certain products or in others, consisting of a tape of self-adhesive articles mounted in a labeling device and whose articles self-adhesive are applied by the latter in the respective printed areas of a strip of any articles, which travels longitudinally through a movement device; said article tape, which can be, for example, a wrapping type packaging tape, which has a succession of equal printed areas, each receiving area of a self-adhesive article and, after being cut, folded and sealed, constituting a wrapping a unit of a product, such as, for example, a bar of chocolate or that holds several units of a product, such as, for example, cookies or others.

[003] For this procedure to work properly the tape of self-adhesive articles and the tape of articles must move at the same speed. It happens that, normally, the labeling device has intermittent movement and speed capability

Petition 870180130204, of 9/14/2018, p. 7/26

2/13 substantially smaller than that of the article tape handling device, which has high speed and continuous movement. To overcome this problem, the only solution has been to make the device for moving the article tape at reduced speed, just like the labeling device. This, however, is not at all desired because the article tape handling device works with idle capacity. To overcome this, a device was previously developed by the same applicant, the subject of another patent application filed under No. PI 0303299-0 on 07/18/2003, which has the main functional characteristic of simultaneously applying several self-adhesive articles aligned and to regular spaces, in order to compensate for the slower speed with which the strip of articles receiving self-adhesive articles has to travel. [004] The mentioned device proved to be efficient, but its use, as occurs with any newly developed invention, showed that improvements could be made and that new applications could be developed from it.

[005] An observation resulting from the tests carried out with the equipment is that the software as it was designed resulted in the overlapping of labels, which is undesirable.

[006] In view of this problem and in order to overcome it, the improved labeling device was developed for simultaneous application of various self-adhesive articles, objects of the present patent, which is essentially understood: by the device itself and by associated software, arranged to eliminate overlapping labels.

[007] Thus, the improved labeling device comprises, in

Petition 870180130204, of 9/14/2018, p. 8/26

3/13 set: the spindle (driven) spindle of the self-adhesive tape feed and an opposed rewinder (motor) set of the liner without the self-adhesive and tape-pull items, both suitable for working with a self-adhesive tape formed by as many parallel longitudinal alignments of self-adhesive articles as there are simultaneous applications to be made.

[008] The device also comprises as many fixed knives as there are simultaneous applications to be made minus a knife, arranged after the unwinder and which cut the tape longitudinally in the spaces between the alignments of self-adhesive articles, thus forming so many strips of self-adhesive articles as many simultaneous applications to be made.

[009] The device also comprises a peeling blade disposed after the fixed knives through which a respective strip of self-adhesive articles passes, where these, at each step of the improved labeling device, are detached and glued to regular spaces, along an axis of the ribbon of articles in a manner known in the art.

[010] The device also includes as many sets as there are self-adhesive articles to be applied simultaneously, minus one set. Each set is formed: by a direction diverter bar; and a peeling blade, through which, at each step of the improved labeling device, a section of the respective strip of self-adhesive articles passes, such that the diverter bar diverts the strip of self-adhesive articles from an offset position to a position aligned with the peeling blade and to the axis of the tape

Petition 870180130204, of 9/14/2018, p. 9/26

4/13 articles; the peeling blade detaches a self-adhesive article that is glued to the axis of the article tape; and a second surface of the diverter bar or another diverter bar diverts the liner, already without the self-adhesive articles, back to the initial position, aligned to the rewinder, where it is rewound.

[011] The device also includes the rewinder axis of the liner and the ribbon traction, located after the stripping blade and the stripping blade (s) and diverter bar assembly (s).

[012] It comprises actuation means basically formed by a stepper motor of the rewinder axis, working in synchronism with the motor of the device for the movement of the tape of articles of self-adhesive articles.

[013] The device includes, additionally, control means formed by the association: at least one optical reader type sensor to "read" sensing marks from the article tape, which have the function of turning the motor on (on); at least one optical reader type sensor to “read” sensor marks from the self-adhesive articles tape with the function of turning the engine off (off); and a software arranged to count the “readings” of the sensing marks of the article tape, so that for each counted quantity equal to the quantity of self-adhesive articles to be applied simultaneously minus one, a signal is sent to turn on the labeler, which gives a advance step in the strips of self-adhesive articles, the first of which passes through the respective peeling blade and the other strip (s) by the corresponding set (s) of diverter bar (s) ( s) of direction and peeling blade (s), so that the self-adhesive articles are detached and glued to the

Petition 870180130204, of 9/14/2018, p. 10/26

5/13 along the axis and in the respective sections of the article tape; said software still arranged to emit a signal to turn off the labeler when “reading” the sensor mark of the tape of self-adhesive articles, at the end of a step and to repeat the cycle.

[014] The labeling device perfected above, in a given step, simultaneously applies the self-adhesive articles to regular spaces along the axis of the article tape and, in the next step, performs a new simultaneous application, thus increasing the application capacity at each step of the labeling device and without the unwanted overlapping of self-adhesive articles, according to the purpose of the invention.

10/13 [032] The improved labeling device also contains a control set formed: by at least one optical sensor 50 intended to "read" the sensing marks 42 of the articles tape 41, an optical sensor 51 intended to “Read” the sensor marks 10 on the self-adhesive articles tape 5; and associated software, arranged to perform the steps (fig. 4):

[033] 1) - Beginning;

[034] 2) - Reset the counter;

[035] 3) - Reads sensor 50;

[036] 4) - Counts the readings of the sensor 50 and compares it with a pre-programmed number “n” (cont = n?), Where “n” = the number of self-adhesive articles applied simultaneously minus one, if the quantity counted # “ n ”(no) ->

[037] 4.1) - account + 1 -> 3) - reads sensor 50, if the counted quantity = “n” (yes) [038] 4.2) - triggers the label (turns the labeler on);

[039] 5) - Read sensor 51;

[040] 6) - Is there a signal? : if it doesn't exist (no) ->

[041] 4.2) - triggers the label; if there is (yes) ->

[042] 6.1) - interrupts the label (turns off the labeler - off); and [043] 7) - Zero counter.

[044] The device is also formed by a supporting structure and panel for interaction with the operator (not shown).

[045] Thus, the device works as follows:

[046] The assembly of the tape 5 of self-adhesive articles in the device is done by cutting the initial section of the tape so that initial sections of strips 9 are formed, so that the first strip 9 is aligned

Petition 870180130204, of 9/14/2018, p. 16/26 / 13 to the “x” axis of the articles tape 41 and is passed through the corresponding first peeling blade 22 and attached to the rewinder 24; the second strip 9 is passed through the corresponding first fixed direction modifier bar 26, being arranged above the “x” axis and then passed through the second peeling blade 22 and attached to the rewinder 24; and if so, the third strip 9 is passed through the respective second direction modifying fixed bar 26 being aligned with the “x” axis of the article strip 41, below the second strip 9 and then it is passed through the third strip strip 22 and stuck in rewinder 24 and so on.

[047] The improved labeling device having the self-adhesive articles tape 5 assembled in the manner described above is disposed above an article tape 41 mounted on its handling device 60.

[048] When the set formed by the labeling device having mounted the self-adhesive articles tape 5 and by the movement device 60 having mounted the article 41 tape is put into operation, the latter starts to move continuously and longitudinally at a given speed and the tagging device is on standby, along which the software, via sensor 50, counts the sensor marks 42 of the article tape 41. When the software counts as many sensor marks 42 as there are self-adhesive articles to be applied simultaneously minus one, it generates a command signal to connect the labeling device and it takes a step on the self-adhesive tape 5, which moves at the same speed as the article tape 41. [049] During the step, the self-adhesive tape 5 passes through the knives cut 25 where it is cut and new sections are formed

Petition 870180130204, of 9/14/2018, p. 17/26

12/13 strips 9 of self-adhesive articles. A section of the first strip 9, already positioned on the first peeling strip 22, passes through it where a self-adhesive article 1 is detached and pasted over a section of the “x” axis in an area 40 of the article tape. Simultaneously, portions of the second and third strips 9 pass through the respective direction modifying bars 26 and change from the lateral direction to the first strip and lateral to each other to positions aligned to the “x” axis and overlapping. Concomitantly, excerpts of said second and third strips of self-adhesive articles 9 already positioned on respective stripping blades 22, pass through them where their self-adhesive articles 1 are detached and glued at points of the “x” axis of areas 40 of the article tape 40 in front of the self-adhesive article 1 detached by the first peeling strip 22 and so that the self-adhesive article from the second strip 9 is in front of the self-adhesive article from the third strip 9 and so on, thus configuring the simultaneous application of several self-adhesive articles at each step of the improved labeling device, compensating for the slower speed at which the article tape moving device 60 has to function to adjust to the speed of the improved labeling device.

[050] At the end of the step, new self-adhesive articles 1 are arranged on respective stripping blades 22 and a corresponding sensor mark 10 of the self-adhesive articles tape 5 is read by the software via sensor 51 and a command signal is generated to turn off the labeler and the whole cycle is repeated.

[051] Within the basic construction, described above, the improved labeling device, object of the present patent, can present
