Definitions
- the present invention relates to the field of the manufacture of packaging, including packaging made from sheets or strips precut, including paper cuts, plastic or cardboard, whether flat, corrugated or mixed.
- the present invention relates to the machine or the module which makes, from a blank or a cardboard cut already grooved, on the one hand the folding of two lateral flaps that fall back in the direction of a central assembly line, with a partial overlap of the outer edge of these flaps, and secondly the gluing of these two parts in the overlap zone for their subsequent maintenance in the folded position which has been imposed by the machine.
- Such a machine is called folder-gluer.
- a blank 10 is flat (see Fig. 1) with a generally rectangle shape with two longer sides, forming the leading edge 11 for the first entering side in the folder-gluer machine, and the rear edge 12 for the side that enters last in the folder-gluer machine.
- this front edge 1 1 and this rear edge 12, which are parallel to each other are generally orthogonal to the axis longitudinal XX 'of the folder-gluer.
- the two lateral sides of smaller length define the right edge 13 and the left edge 14 which are parallel to each other and to the longitudinal axis XX 'of the folder-gluer.
- the right edge 13 is the lateral side which is located to the right of the longitudinal axis of the folder-gluer
- the left edge 14 is the lateral side which is located to the left of the longitudinal axis XX 'of the folder-gluer.
- the right and left edges 1 3, 14 have a cut along their two end portions so as to define a right leg 1 3a and a left leg 14a in the central portion of the right and left edges 13, 14.
- Two longitudinal lines represented in dashed lines correspond to the fold lines, materialized by the right longitudinal groove 15 and the left longitudinal groove 16, between which is delimited the central flap 1 9. Between the right groove 1 5 and the right edge 1 3, there is the right flap 17 and Between the left longitudinal groove 16 and the left edge 14, there is the left flap 18.
- Figs. 2 and 3 show the blank 10, after folding and folding the two flaps 1 7 and 18 one on the other, and after bonding between the right leg 13a and the left leg 14a, in an ideal conformation.
- the right tab 14a is sticking directly on the flap 17 at the edge 13.
- the right side 15 'of the folded-glued cutout 1 0' is obtained at the location of the right longitudinal groove 1 5
- the left side 1 6 'of the folded-glued cut 10' is obtained at the location of the left longitudinal groove 16.
- the straight edge 13 and the left edge 14 are spaced from each other, at the cutouts, a gap Greef forming a reference gap of predetermined value and constant along the cuts.
- Greef is found at the location of the front edge 1 1 and the location of the trailing edge 12.
- a first anomaly of positioning of the two lateral flaps, called gap corresponds to a too large spacing between the right and left edges 14 of the two flaps 17, 18 folded and glued: a representation of this first anomaly is visible in FIG. 4, with a gap G 'forming a larger gap than the Greef.
- a second positioning anomaly of the two lateral flaps 1 7, 18, called fishtailing corresponds to a lack of parallelism between the edges 1 3 and 14 of the two side flaps 17, 18 folded and glued, most of the time accompanied by the same defect. parallelism between the sides 1 5 'and 1 6'.
- a first configuration of this second anomaly is visible in FIG. 5: in this case, the edges 13 and 14 are convergent towards the front edge 1 1 so that they define a gap G 1 smaller (and possibly negative) between the front ends of the edges 13 and 14 than the gap G2 defined between the rear ends of the edges 13 and 14. In this case of rear fishtailing or open fishtailing, an angle a1 between the edges 1 3 and 14 is measured from the rear edge 1 2.
- edges 13 and 14 are divergent in the direction of the front edge 1 1 and converge toward the rear edge 12, so that they define a gap G 1 larger (and possibly negative) between the front ends edges 13 and 14 that the gap G2 defines between the rear ends of the edges 1 3 and 14.
- an angle a2 between the edges 1 3 and 14 is measured from the front edge 1 1.
- EP 1932658 discloses a method and a folder-bending machine which uses, at two successive alignment modules, an alignment rule whose orientation with respect to the longitudinal direction of the machine is modifiable, so as to allow by this angular offset, which is imposed on one and then on the other sides of the folded cutout, to make up at least part of the misalignment between the two right and left edges 13 and 14.
- This solution makes it possible to rectify in a systematic way the part of the misalignment which results from the mechanical movements of the machine and not from the shape or the reaction to the folding and other treatments specific to each carton blank.
- position sensors make it possible to detect these anomalies after treatment of the cut in order to identify and eject the packages concerned by anomalies exceeding a predetermined dimensional tolerance threshold. Also, in the machines of the prior art, the correction of the identified anomaly systematically goes through the modification of the setting of the moving parts of the machine, but does not take into account the deformation of the particular cut from its non-compliant position in the machine, improper folding, improper cutting (contour), or improper grooving.
- Another object of the present invention is to ensure the reliable locking of the central flap during the control of the position and the possible correction of the position of the right flap and / or the left flap.
- the input of the upper face of the folded right flap and the folded left flap during step f2) is carried out respectively by at least one suction cup with vacuum, and in that the correction of the position of the left flap and / or of the right pane during step f3) is performed by moving the suction cup with vacuum.
- suction cups with partial vacuum allows to grasp and rectify the position of the folded right door and / or the folded left door, and this also without damage.
- Such a method can be implemented while the position of the cut, in the longitudinal direction of the folder-gluer, is substantially the same throughout the correction procedure. According to another embodiment, the method is implemented while the cutting advances in the longitudinal direction of the folder-gluer, either continuously or by jerks.
- a device for correcting the position of a cut in a folder-gluer for a substantially flat cut comprising a straight edge, a left edge, a front edge, a rear edge, a right longitudinal groove and a left longitudinal groove, the right longitudinal groove and the left longitudinal groove delimiting, with the right edge and the left edge at least three flaps among which a right flap, a left flap and a central flap, the device comprising:
- adhesive means capable of applying glue in an area of the right flap adjacent to the right edge and / or in an area of the left flap adjacent to the left edge, so that glue is present in a covering portion between the right pane and the left pane,
- such a device makes it possible to fold upwards both the right flap and the left flap, over the central flap which is well held, folding the folded right flap and folded left flap which is find one over the other at least in the overlap portion, the glue application, the control of the position of the right and left flaps, the possible realization of the correction of the position of the right flap, the left pane or both the right pane and the left pane, and maintaining the corrected position during the support between the right pane and the left pane in the covering portion until the glue.
- the order of operations mentioned above is not fixed, the glue can be installed before or after folding, before or after the position check, or before or after the possible correction.

- FIG. 7 illustrating the principle of the method for correcting an excessively large gap, namely with G '- Glef> 0.
- a positional deviation is detected, namely the distance between the right edge and the left edge or gap, which is not in accordance with FIG. the permissible range, as for the gap G 'of FIG. 4 or FIG. 7, the following procedure is performed. After blocking of the central flap 19, the capture of the upper face of the right flap 17 folded by two suckers 21, 23 offset in the longitudinal direction and the gripping of the upper face of the left flap 18 folded by two suckers 24, 26 offset in the longitudinal direction are performed simultaneously.
- the four suction cups 21, 23, 24 and 26 are lowered to come into contact with the folded right flap face 17 facing upwards and with the face of the folded left flap 18 facing upwards.
- the four suckers 21, 23, 24 and 26 being vacuumed during the capture, a safe grip of the right pane 17 in two locations and the left pane 18 in two locations is obtained.
- the position of the left flap 18 and / or the right flap 16 is corrected by lateral displacement of the two suction cups 21, 23 of the right flap 16 and / or of the two suction pads 24, 26 of the left flap 18, to change the distance between the right edge 13 and the left edge 14 to bring it back into the allowable range.
- the two straight suckers 21 and 23, including the right front suction cup 21 and the right rear suction cup 23, are moved together.
- the pair of straight suckers 21, 23 is moved to the left.
- the two left suction cups 24 and 26, comprising the left front suction cup 24 and the left rear suction cup 26, are moved together.
- the pair of left suction cups 24, 26 is moved to the left.
- Figs. 8 and 9 respectively illustrating the principle of the correction method for rear fishtailing or front fishtailing.
- a positional error is detected in the form of a parallelism defect between the right edge 1 3 and the left edge 14, with a value of angle a1 or a2 exceeding a maximum allowable value, it is in the presence of a folding result not in accordance with the allowable range, and as for Figs. 5 and 6, the following procedure is carried out.
- the four suction cups 21, 23, 24 and 26 are lowered in right and left pairs, until coming into contact with the folded right flap face 17 facing upwards and with the folded left flap face 1 8 turned up.
- the front suction cup 21 and 21 of each pair is placed under vacuum.
- the rear fishtailing is corrected by lateral displacement of the front suction cups 21 and 24 towards the outer lateral sides of the folded cutout 10, which are located on the same flap as the suction cup.
- the right front suction cup 21 is moved towards the right side 15 ', ie to the right
- the left front suction cup 24 is moved towards the left side 16', ie to the left.
- the front fishtailing is corrected by a lateral displacement of the front suction cups 21 and 24 towards the outer lateral sides of the folded blank 10 which are located on the flap different from that on which the suction pad concerned is located.
- the right front suction cup 21 is moved towards the left side 1 6 ', ie to the left, and the left front suction cup 24 is moved towards the right side 1 5', namely to the right.
- the angular position of the left flap 18 and / or the right flap 16 is corrected using, for the right pane 1 6 and for the left pane 18, a single sucker which is vacuumed to perform the seizure of the corresponding flap, and which remains under vacuum during its lateral movement, whereby we change the orientation of the shutter right 1 7 and / or left pane 18 to bring the right edge 1 3 and the left edge 14 substantially parallel to each other.
- this maneuver for modifying the angular position of the right pane 17 or the left pane 18, or both of the right pane 17 and of the left pane 18, also functions by partial evacuation and lateral displacement of one or the other of the front suction cup 21 (24) and the rear suction cup 23 (26): this entry at a single point of the flap in question, makes it possible to modify the angle formed between the edge of this shutter and the axis XX 'as far as this point of engagement of the flap by the suction cup is not placed in the middle of the length (extended along the axis XX' of the folder gluer).
- the invention also allows to act and rectify the two anomalies.
- the correction of the gap is effected by lateral displacement of the two suction cups of each pair, right and left, the four suction cups 21, 23, 24 and 26 being in engagement with the right and left flaps 17, according to the previous explanations of FIG. 7. Then, we stop the suction of one of the two suction cups of each pair to correct the fishtailing as discussed above in connection with FIGS. 8 and 9.
- the correction means comprise at least one suction cup for gripping the right flap 17 and at least one suction cup for gripping the left flap 18, the suction cups being oriented downwards, vertically movable and cross direction and able to be subjected to vacuum.
- the correction means comprise a pair of straight suction cups 21, 23 and a pair of left suction cups 24, 26.
- a first suction cup 21 (24) is located at the front and a second suction pad 23 (26) is located at the rear. Moreover, the vacuuming of the first suction cup 21 (24) is controlled independently of the evacuation of the second suction cup 23 (26).
- the two suction cups 21, 23 of the pair of straight suction cups are mounted on a straight support 31 for simultaneously moving the two suction cups 21, 23 and the two suction cups 24, 26 of the pair of suction cups. on the left support 32 for simultaneously moving the two suction cups 24, 26.
- the simultaneous displacement of the two suction cups of each pair is carried out in a transverse direction (orthogonally to the direction of advancement A) and height.
- Figs. 1 0 and 1 1 in order to follow the stroke of the cut 1 0 according to the direction of advance A while the correction is performed by the suction cups 21, 23, 24, 26, the right support 31 (left 32) is mounted by a straight square 33 (left 34) to the rod 35 (36) of a straight linear motor 37 (left 38).
- Figs. 1 0A and 1 1 A there is shown a first position corresponding to the rest position, pending the arrival of a new cut and on the Figs. 10B and 11B, there is shown a second position corresponding to the end position when the cut has been folded, glued and possibly corrected.
- optical detection means To control the position of the right edge 1 3 and the left 14 after folding the right flap 1 7 and the left flap 18, it is preferably used optical detection means, not shown.
- optical detection is used as described in EP 0937573.
- These detection means measure the difference between the right edge 13 and the left edge
- the right support 31 and the left support 32 has a longitudinal stroke (along the axis XX 'of the folder gluer) of 200mm thanks to the linear motors 37 and 38.
- This longitudinal stroke can follow the cutout 10 during part of its advance while performing the correction during the advance along the advancement direction A.
- the right support 31 and the left support 32 has a transverse travel (in the orthogonal direction to the XX 'axis of the folder gluer) between 10mm and 30mm. This transverse stroke is sufficient to make up for the anomalies encountered in most cases in the case of a cut of maximum size, for example 1 100mm by 1700mm.
- Pressure means for making a pressure contact between the right flap 17 and the left flap 18 in the covering portion.
- Figs. 1 1 A, 1 1 B, 1 3, 14, 15, 1 6A, 1 6B, 17A and 17B for the lower part of the correction device which completes the elements allowing the advance of the cut in the longitudinal direction by means locking the central flap 19.
- the elements allowing the advance of the blank 10 are endless belts 60, visible in number three in Figs. 16A, 16B, 17A and 17B and arranged parallel to each other under the suction cups 21, 23, 24, 26.
- These locking means are intended to retain the cutout 10 by its central flap 19 by preventing it from lifting, or to move laterally including. Without this retention of the cut by its central flap 19, the correction of the position of the right flap 17 and / or the left flap 18 could not be effected with efficiency and precision.
- these locking means 70 of the central flap 19 uses (see Figs 13 to 17), as a gripping means of the central flap 19, a depression vacuum vacuum of the underside of the central flap 19.
- the blocking means 70 comprise at least one ramp 71 equipped with nozzles 72 oriented upwards and able to perform a vacuum.
- the outlet of these nozzles 72 opens on a support plate 75 on which the cutout 10 rests while being able to be driven by the belts 60.
- two ramps 71 are each arranged along the one and the Other external belts 60.
- the nozzles 72 act as suction cups by sucking down the underside of the central flap 19 when they are supplied with air under partial vacuum.
- a pressurization module 73 supplies partial ramp air 71 to the ramps 71 via the pipes 74.
- the ramp 71 is mounted (see Figs 13 to 17) on a linear motor 80 accompanying the cut 10 during its travel along the longitudinal direction of the folder-gluer machine.
- a linear motor 80 accompanying the cut 10 during its travel along the longitudinal direction of the folder-gluer machine.
- the linear motor 80 is placed along the transport means that advance the cut along the longitudinal direction of the folder-gluer.
- these means of transport are endless belts 60.
- three endless belts 60 are arranged over the width of the module of the folder-gluer, and along and outside the two outer belts, is mounted a ramp 71.
- between each pair of belts 60 is mounted a ramp 71.
- the cutouts 10 are driven by the belts 60 and are pressed down when the evacuation of the ramps 71 is activated.
- the linear motors 80 accompany the longitudinal stroke of the blank 10 in all cases, whether or not correction.
- the linear motors 80 are retracted and returned to the initial position rapidly after the departure of the blank 10 from the correction device and before the arrival of the next blank 10 in the correction device.
- the correction means suction cups 21, 23, 24, 26
- the blocking means pramps 71
- the correction means suction cups 21, 23, 24, 26
- the blocking means pramps 71
- synchronization is effected between the motor controlling the longitudinal travel of the right support 31 and the left support 32 and the motor controlling the linear motors 80 supporting the suction nozzles 71.
- the gluing is carried out before folding the right flap 17 and the left flap 18. It is however essential to avoid the glue taking in the covering portion between the right flap 17 and the left flap 18 before and during control of the position (ie during steps d), e)), and during the eventual position correction (step f)).
- it prevents the contact between the right flap and the left flap by an element 90 inserted between the right flap 17 and the left flap 18, and before step g) the element 90 is removed and contact is made under pressure between the glue, the right flap 17 and the left flap 1 8 in the covering portion, preferably until the glue.
- the correction device therefore preferably also comprises a member 90 adapted to be inserted between the right flap and the left flap before folding, and able to be removed after the correction.
- a member 90 adapted to be inserted between the right flap and the left flap before folding, and able to be removed after the correction.
- FIG. 1 3 we see a partial representation of this element 90 which can be in the form of a rod fixed by its rear end from the top and allowing the passage of the cut just below the element 90. It s is an embodiment where the folding and the correction of the cut is performed during the advance of the cutout 10.
- the right flap 1 7 and the left flap 1 8 are found above the rod, itself above the central flap 1 9.
- this element 90 is dispensed with: it then acts to correct the position of the right flap 18 and the left flap 17 relative to the central flap 19, in a sufficiently short time to allow this correction before taking glue.
- a folder-gluer may also be a folding-gluing unit, mounted for example in an in-line machine, downstream of a flexo printing, and a rotary cut.
- the linear motors 37, 38 and 80 can be replaced by cylinders.
