Definitions

  • the present invention relates to the field of manufacturing packaging, and in particular packaging made from pre-cut sheets or strips, in particular cutouts of paper, plastic or cardboard, whether flat, corrugated or mixed.
  • the present invention is used in the field of manufacturing folding boxes.
  • the present invention relates to a device making it possible to control the quality of blanks circulating in a processing machine such as a folder-gluer machine.
  • each cutout is thus held from above at the level of its internal face, so that its printed face, which is turned downwards, is entirely clear.
  • the inspection from below is carried out using a camera which is installed under the vacuum conveyor, and which operates from a low angle. Associated with a suitable lighting system, the camera takes a picture of each printed side as the cutouts pass by.
  • the circulation path of the cut passes in a section with a background element which improves the control of the contour and which is located between two distinct and slightly spaced sections of the circulation path, each provided with a box in which a vacuum is generated to hold the blank pressed by its upper face against a conveyor belt, while its printed lower face is controlled.
  • defects are defined by way of example as being in particular respectively printing errors in the text, colors, color register, etc., embossing errors, other appearance defects, such as holes, breaks, tears, etc., cutting errors, oil stains, and more.
  • An aim of the present invention is to propose an improved control device which ensures a stable position of the blank when it passes in front of the means of inspection and control of its surface.
  • the optical control device comprising suction means which delimit three successive distinct suction sections along the circulation path, including a central suction section which extends opposite the inspection means, a section of upstream suction and a downstream suction section.
  • Such a device makes it possible to regulate the depression making it possible to suck up and retain the cut against the conveyor belt at the level of the central suction section and therefore at the level of the inspection means.
  • the most suitable depression intensity can be chosen to stabilize the cut for inspection by the inspection means.
  • control device further comprises, opposite the inspection means, means for tensioning the conveyor belt.
  • tensioning means can be arranged to guarantee flatness of the conveyor belt so that the position of the cutout on the belt allows optimal optical control, thanks to a controlled and constant orientation of the cutout relative to partly to the lighting system and partly to the camera.
  • the invention can be implemented whatever the direction of movement of the cutouts, by accordingly adapting the arrangement of the conveyor belt, the inspection means and the suction means, along the path of circulation of cuts.
  • Such a control device can be carried out during the movement of each cut which is made with the printed face turned downwards, for example by holding the cut from above, while the inspection of the printed face is carried out. from below.
  • control device so that each blank moves via the conveyor belt with its printed side facing upwards, so that the inspection is carried out from above, and for example the cutting is maintained from below.
  • control device is also possible in the case where the movement of the cutouts is carried out in a substantially vertical plane.
  • the present invention also relates to a blank processing machine according to claim 12, and to a folder-gluer machine according to claim 13, equipped with a control device according to claim 1.
  • Fig. 1 represents a folder-gluer machine 100, that is to say a processing machine which is responsible for folding and gluing blanks in order to manufacture folding boxes. Equipped with a modular structure, this folder-gluer 100 is conventionally composed, from upstream to downstream, of a feeder module 110 or margin table, of an alignment module 120, of an embossing module 130 , in particular for Braille, a fold pre-breaking module 140, a gluing module 150, a folding module 160, a transfer module 170 and a reception module 180. cutouts move from upstream to downstream from one module to another in the folder-gluer machine 100, in the longitudinal direction (direction of Arrow A visible on the Figs. 1 And 2 ).
  • the folder-gluer 100 is further provided with a control device 10 which is integrated directly between the alignment module 120 and the embossing module 130.
  • This control device 10 is intended to carry out online quality control at the within the folder-gluer 100 itself, by systematically inspecting all the cutouts 12 which circulate there with their printed face 13 facing downwards (lower face), and their internal face 14, not printed, facing upwards (face higher).
  • the control device 10 (see Fig. 2 ) comprises a vacuum conveyor 20.
  • the conveyor 20 firstly comprises a conveyor belt 22, which is responsible for continuously conveying each cutout 12.
  • Each cutout 12 is conveyed while being held from above at the level of its upper face 14 , intended to constitute the internal face of a box, along a given circulation path 15.
  • This conveyor belt 22 is set in motion by the motor 23 in an endless loop.
  • the control device 10 also has inspection means 30 making it possible to inspect from below the lower face 13 of each blank 12 during its transport along the circulation path 15 which passes right through the control device. 10, from right to left on the Fig. 2 .
  • the inspection means 30 include in particular a camera 32 and a lighting system 31 oriented and converging (see drawn lines in Fig. 2 ) towards the same control zone 33.
  • the control zone 33 can for example be in the form of a transverse line or a transversely elongated rectangle located at the level of the circulation path 15.
  • the cutout is retained by the conveyor belt 22 along the circulation path 15 which follows the substantially horizontal and flat lower section of the conveyor belt 22. More precisely the cutout 12 is retained by suction against the underside of the conveyor belt 22 by means of the suction means 40 arranged above the conveyor belt 22 along the circulation path 15 of the cutout 12.
  • the conveyor belt 22 operates at the level of three distinct sections 41, 42 and 43 of the circulation path 15, crossed successively by the cutout 12.
  • An upstream suction section 41 is followed by a central suction section 42, which extends opposite the inspection means 30, and which is followed by a downstream suction section 43.
  • the cutout 12 is perfectly pressed against the conveyor belt 22 between the inspection means 30 and the conveyor belt 22.
  • Each of the sections, the central suction section 42, the upstream suction section 41 and the downstream suction section 43 comprises a box in which a depression is generated (Arrows V in Fig. 2 ). More precisely, an upstream box 41a, a central box 42a and a downstream box 43a are respectively aligned in the direction of advancement A.
  • the boxes 41a, 42a and 43a are located above and behind the conveyor belt 22, itself located above and behind the cutout 12, which is itself located above and behind the inspection means 30, during visual inspection of its lower face 13 printed and/or bearing reliefs .
  • the conveyor belt 22 is kept flat and continuous over the entire lower surface extending along the circulation path 15 of the distinct sections 41, 42 and 43 and the boxes 41a, 42a and 43a.
  • the central suction box 42a comprises at least one suction opening, the opening(s) opening directly to the control zone 33.
  • each box 41a, 42a and 43a can communicate with a vacuum pump.
  • This solution with an individual suction pump for the upstream box 41a, the central box 42a and the downstream box 43a is not always possible, in particular for reasons of bulk.
  • the presence of three vacuum pumps presents a significant cost.
  • the vacuum conveyor 20 comprises a first vacuum pump 44 and a second vacuum pump 45.
  • the first vacuum pump 44 is coupled and communicates with the upstream suction box 41a of the upstream suction section 41.
  • the second vacuum pump 45 is coupled and communicates both with the central box 42a of the central suction section 42 with the downstream box 43a of the downstream suction section 43.
  • the air under vacuum is shared between the central box 42, used to maintain a section of the strip 22 facing the inspection means 30, and the downstream box 43, used to maintain the section of the strip 22 located downstream of the inspection means 30 .
  • This sharing of the suction provided by the second vacuum pump 45 can be carried out according to a distribution chosen according to the data and dimensions of the control device 10, and in particular the volume of the central box 42a and the downstream box 43a.
  • a distribution chosen according to the data and dimensions of the control device 10, and in particular the volume of the central box 42a and the downstream box 43a For example, less than half of the outlet section of the second vacuum pump 45 is coupled to the central box 42a of the central suction section 42.
  • less than a third less of the outlet section of the second vacuum pump 45 is coupled to the central box 42a of the central suction section 42.
  • of the order of a third of the outlet section of the second vacuum pump 45 is coupled to the central box 42a of the central suction section 42.
  • the central box 42a and the downstream box 43a respectively represent the order of 5% and 95% of the total volume formed by the central box 42a and the downstream box 43a.
  • At least one of the upstream box 41a, the central box 42a and the downstream box 43a has an adjustable suction volume.
  • the upstream box 41a and the downstream box 43a have a modifiable volume.
  • Such modularity is obtained for example by compartmentalizing the upstream 41a and downstream 43a boxes, with internal walls and by equipping the upstream 41a and downstream 43a boxes with a movable shutter at the entrance to each compartment, which can be opened or closed at will.
  • the upstream box 41a and the downstream box 43a comprise a lower perforated wall, extending along the circulation path 15; the conveyor belt 22 has a perforated structure, which is able to slide against each perforated wall.
  • the strip 22 at least partially covers the width of each perforated wall of the upstream box 41a and the downstream box 43a. According to a preferred arrangement, the strip 22 substantially completely covers the width of each perforated wall of the upstream box 41a and the downstream box 43a.
  • the outlet section of the central box 42a is of small amplitude, and is not equipped with a perforated wall.
  • the vacuum conveyor 20 comprises tensioning means 50 of the belt 22, ensuring local rigidity of the belt 22.
  • These tensioning means 50 comprise a pair of rollers 51 and 52 spaced apart along the circulation path 15. More precisely, each upstream roller 51 and each downstream roller 52 is arranged above the conveyor belt 22. The vacuum generated by the central box 42a will press the belt 22 at the level and against these fixed rollers 51 and 52, which will ensure a flat inspection surface.
  • the rollers 51 and 52 are located along the central suction section 42. Furthermore, preferably, the rollers 51 and 52 respectively delimit the upstream position and the downstream position of the central suction section 43. Concretely the outlet of the central box 43a extends along the direction of advancement A between the rollers 51 and 52. For example, the rollers 51 and 52 are spaced from one another along the direction of advancement A d 'a distance of around 30mm, and preferably between 20mm and 50mm.
