Definitions

  • the present invention relates to a device for breaking attachment points connecting two edges of a cutting line formed on cardboard blanks before folding, including a frame bearing means for transporting said blanks along a trajectory substantially flat and two parallel shafts, rotatably mounted on one side and on the other side of the plane of said trajectory, comprising tools for inducing a shear between the edges adjacent to said cutting line during their displacement, in order to break said attachment points.
  • a neighboring device has already been proposed, for example, in the patent EP 0 680 821.
  • This device is intended more particularly to break the fibers of cardboard which may accidentally remain in cutouts whose different panels are separated by simple cutting lines.
  • the problem to be solved is, however, quite comparable to that discussed above.
  • the object of the present invention is to remedy, at least by part, to the disadvantages of the aforementioned device.
  • the subject of this invention is a device as defined by claim 1.
  • This device allows it in particular a great flexibility of use and adaptation to cardboard cutouts dimensions likely to vary significantly. This new design also makes it easier to adjust the position of the tools, allowing to increase productivity.
  • the device illustrated by Figures 1-3 has a frame formed essentially of two vertical parts, left and right, respectively 1 and 2, kept apart from each other by several spacers 3.
  • Two cradles, one upper 4a, the other lower 5a, are associated to the left part 1 of the frame and two other cradles, upper 4b, lower 5b are associated with the right part 2 of the frame.
  • Each of these cradles 4a, 5a is pivotally mounted on the left part 1 of the frame by a pivot axis 6, respectively 7.
  • Each of the cradles 4b, 5b is pivotally mounted on the part straight 2 of the frame by a pivot axis 8, respectively 9.
  • the two upper cradles 4a, 4b carry a first tool-holding shaft 10, while the two lower cradles 5a, 5b carry a second tool-carrying shaft 11.
  • the two upper cradles 4a, 4b are associated with a device adjustment 12 worm screw, acting on two connecting rods 12a, 12b connected to ends of the respective cradles 4a, 4b opposite the pivot shafts 6, 8 and intended to pivot these upper cradles 4a, 4b around these pivot axes 6, 8.
  • Another similar adjustment device 13 makes it possible to rotate the lower cradles 5a, 5b around the pivot axes 7, 9, by means of two connecting rods 13a, 13b.
  • Each tool-holder shaft 10, 11 is integral with a motor synchronous drive M1, respectively M2.
  • the tool shafts 10, 11 are kinematically connected to coaxial shafts 14, respectively 15 to the pivot axes 8, 9 of the cradles 4b, 5b, by toothed belts 16, respectively 17.
  • the shafts 14, 15 cross the straight part 2 of the frame, as can be seen in Figure 2, to extend on both sides of this right part 2.
  • the external portions of the shafts 14, 15 are connected kinematically by a belt 18 notched on its two faces, so that the angular positions of the two tool shafts 10, 11 are constantly synchronous.
  • one of the motors M1, M2 must be controlled to the other. In this example, it is the motor M1 which is slaved to the motor M2.
  • the control device will be described in relation to FIG. 6.
  • Each tool shaft 10, 11 is provided with a keyway 10a, 11a for the angular positioning of annular tool supports 19a, 19b, 20a, 20b.
  • These tool holders always go in pairs and face each other, the tools of a tool support 19a secured to the upper tool holder shaft 10 cooperating with the tools of the tool support 19b, integral with the tool-holder shaft lower 11.
  • annular tool supports 19a, 19b, 20a, 20b are illustrated in on a larger scale in FIG. 4. Only one of them 19b will be described here in detail, since they are all identical.
  • This tool support 19b includes a discoidal ring 21 in the shape of a circular sector, the angular opening of which is dimensioned to allow the passage of one of the tool-holder shafts 10, 11.
  • the discoid rings 21 of two tool supports 19a, 19b of the same pair are intended to be coplanar, i.e. they will be positioned to occupy the same axial positions along their tool shafts respective, 10, 11.
  • the discoidal ring 21 is integral with a first half collar of clamping 22 of diameter corresponding to that of said tool-holder shafts 10, 11, provided with an internal groove 22a intended to cooperate with one of the grooves of key 10a, 11a of the tool-holding shafts 10, 11.
  • a second half collar of clamping 23 of diameter corresponding to that of said tool-holder shafts 10, 11, connected to the first half clamp 22 by two clamping screws 24, 25, allows to axially immobilize the tool support 19b along the tool holder shaft 11 by clamping this shaft between the two half clamps 22, 23.
  • the discoidal ring 21 has a positioning projection annular 21a, pierced with a plurality of openings in an arc 26 coaxial to the discoid ring 21.
  • a similar annular positioning projection and of the same diameter as the projection 21a (not visible) is formed on the other face of the discoid ring 21.
  • Different tools 27 for breaking the attachment points connecting two edges of a cutting line of a cardboard blank are angularly positioned along these annular projections thanks to shoes positioning 27a in which is formed a groove of positioning 27b intended to come into engagement with the annular projection 21a.
  • part of the tools 27 extends on one side of the median plane of the discoid ring 21, while the other part of these tools extends on the other side of this same median plane.
  • the tools 27 of two tool supports 19a, 19b of the same pair of supports of tools that extend from one side of this midplane and those that extend from the other side of this median plane describe two parallel circular paths and adjacent, since the discoid rings 21 of the two tool supports 19a, 19b are coplanar.
  • peripheral edges of some of these tools 27 describe larger circular paths diameters than the peripheral edges of other tools 27.
  • the trajectories of smaller diameter of the peripheral edges of the tools 27 are chosen for be substantially tangent to the planar trajectories of the cuts displaced by the transport device which will be described later, so that these tools 27 play a role in supporting the cuts.
  • Edges peripherals of other tools 27, whose trajectories are larger diameters, are adjusted to penetrate the planar trajectory of the cutouts carton transported by the transporter.
  • the transport mechanism which will now be described is disposed between the left 1 and right 2 parts of the frame. As the situation of this mechanism would make it difficult to see, it is shown separately to make the drawing easier to read. It has a lower part 30 and two upper parts 31a, 31b.
  • the lower part has a band endless conveyor 32 guided by a plurality of rollers 33 and driven by a motor 34. Part of the rollers 33 are arranged in a plane corresponding to the transport path of the cardboard blanks.
  • the strip endless conveyor 32 is guided by a series of rollers 33a, for form a loop 32a extending below the plane of the trajectory of transport.
  • This loop 32a provides space corresponding to the size of the tool support 19b carried by the lower tool shaft 11.
  • the loop 32a is shown closed, its two ends 32b joining substantially at the point of tangency of the strip conveyor 32 with the circular path of the tool support 19b.
  • the rollers 33 of the transporter defining the lower part of the transport mechanism horizontal are each distributed symmetrically with respect to this point tangency, in three sections, a section in which the rollers 33 are mounted on a slide 35, followed by a section comprising, in this example, two rollers 33b secured to a removable support 36 and finally a section where the rollers 33 are directly mounted on the frame 37 of the transport mechanism 30.
  • Some of the guide rollers 33 of the strip conveyor 32 also play the role of tension rollers 33c, mounted on mobile supports (not shown), solicited by means mechanical (not shown) which constantly tend to maintain the tensioned conveyor belt. The adjustment of the opening and closing of the loop 32a of the conveyor belt 32 will be explained below.
  • the two upper parts 31a 31b of the mechanism transport are arranged in mirror symmetry with respect to the axis connecting the centers of the two tool shafts 19a, 19b. These two parts 31a, 31b being similar, only one of them will be described.
  • Each part 31a, 31b has an endless conveyor belt 38a, 38b guided by rollers 39, part of which forms a flat surface parallel and adjacent to the part plane formed by the rollers 33 of the lower part 30 of the conveyor. In outside the rollers 39 forming the flat surface, certain rollers play also the role of tension rollers 39c, like the rollers 33c of the part lower 30 of the transport mechanism.
  • the rollers 39 forming the flat transport parts are grouped into a plurality of bogies 40 subjected to pressure means elastic (not shown), for pressing the conveyor belts 32 on the one hand and 38a, 38b, on the other hand against each other.
  • a first part of these bogies 40 are articulated around horizontal axes parallel to the axes of the rollers 39 on a slide 41.
  • the following bogie is integral with a removable support 42.
  • the following bogies 40 are integral with a fixed support 43.
  • a photoelectric detection cell 44 is arranged at the input of the transport device and is intended to detect the edge before each cardboard cutout arriving in the device to break the stitches of attachment.
  • This angular position of the tool-carrying shafts 19a, 19b is constantly known thanks to two pulse generators G1, G2 associated with the respective synchronous drive motors M1, M2 and transmitting their information to microprocessor 45. So when the edge before a cut is detected, the microprocessor 45 knows the position tools angular 27 on the tool supports 19a, 19b, 20a, 20b mounted on the tool shafts 10 and 11. He also knows the distance between the edge before cutting and the line joining the axes of the tool-holder shafts 10, 11. He can then determine the angular correction to be made.
  • the microprocessor 45 performs this correction by calculating, from the collected data, an acceleration or deceleration, as well as a period during which this correction must be applied to the motors synchronous drive M1, M2, so that the tools 27 are in the angular position desired to perform the point breaking operation of connection at the determined location of the cardboard cutout
  • the first job is to choose the tool supports 19a, 19b, 20a, 20b depending on the size of the cut.
  • the length tool holder device should match the length of the cut measured in the direction of its transport F, to which we will add a certain length corresponding to an average spacing between the cuts, the precise adjustment being carried out by microprocessor 45 (figure 6), following the detection of the front edge of each cut by the cell 44, as explained above.
  • the following operation consists in positioning and fixing the supports of annular tools 19a, 19b, 20a, 20b on the tool shafts 10, 11.
  • the positioning precise angularity is ensured thanks to the internal groove 22a of the half collar of clamping 22 which can be engaged, using a key (not shown) in the keyways 10a, 11a of the tool shafts 10, respectively 11.
  • a key not shown
  • tool supports 19a, 19b, 20a, 20b will be positioned longitudinally along the tool shafts 10, 11.
  • the device object of the invention makes it possible to adapt to a range of dimensions and types of extremely wide cardboard cutouts and that the operations of adjustment are simple to perform.
  • This device not only allows position the tools 27 angularly and longitudinally (or transversely if we refer to the direction of transport F of the blanks), but also to change the diameters of the tool supports 19a, 19b, 20a, 20b to adapt to cuts of different dimensions.
  • the detection of the front edges of the cuts by the cell 44 and the adjustment of the angular position of the tools 27 by the microprocessor 45 allows greater flexibility and time savings adjustment, since the spacing between the cuts can vary. Adjustment angle of the tools 27 as a function of variable spacings of the cutouts of cardboard leads to a gain in productivity, since the number of cuts processed per unit length by the device according to the present invention can be increased.
