Definitions

  • the present invention relates to a cutting press, in particular that used for cutting sheet or strip material for the production of packaging, and as defined in the preamble of claim 1.
  • the movement, from bottom to top and from top to bottom, of the lower bed of such a press can be carried out using a system with four connecting rods - cranks, or with four knee pads - cams.
  • the top dead center of the drive system corresponds to the working position, for example of cutting, of the press, position in which the counter-tool fixed on the lower movable bed base is pressed against the tool carried by the upper bed base.
  • such presses are so designed that, during the same working operation, several cuts or blanks of the same shape and dimensions can be obtained simultaneously from a single sheet whose total area is at least equal to that of the addition of all the cuts.
  • the tool and the counter-tool are each in the form of a plate, in principle rectangular, of large dimension, carrying on one side the working members, the other side coming to be pressed against one side. of the corresponding box spring, face whose surface will be at least equal to, if not greater than, that of the tool or counter-tool.
  • the patent CH-A-652967 describes a cutting press in which the drive system of the lower movable bed base is produced using a system with four knee-cams.
  • the parallelism between the two bed bases is obtained by means of a single key slid between the bearing of each toggle joint and the lower cross member of the frame. In this case, the "placing" operation is also necessary.
  • the sheet since a cutting press is also designed so that the same tool can be used for sheets of various dimensions, the sheet generally only occupies part of the total area of the tool . However, because the sheet is generally placed, during its cutting, on the side of the downstream edge (with reference to the direction of travel of the sheet) of the tool, this only partial occupation of the active surface of the tool causes an imbalance in the distribution of the cutting pressure, imbalance which will propagate on the lateral uprights of the frame, causing different elongations there for each of them, and thereby a lack of parallelism between the two bed bases.
  • the present invention essentially aims to achieve an adjustment of the parallelism of the two bed bases of a cutting press which makes it possible to obtain perfect parallelism between the two bed bases under pressure and thus shorten the preparation time of the tool by eliminating almost completely the "setting" and the use of forms of compensation.
  • Figure 1 shows a cutting press comprising a frame consisting of an upper crosspiece 3, a lower cross member 1 and lateral uprights 2 connected to the cross members 1, 3, using screws 26 and rails 25 engaged with corresponding grooves made in the cross members 1, 3.
  • An upper bed 5 is fixed on the upper cross member 3.
  • On the lower surface of the bed base 5 is mounted a tool 4.
  • a lower mobile bed base 6, displaceable by means of a drive system with four toggle knobs 20a, 20b, and cams 24.
  • the knee pads 20a, 20b are supported, using bearings 33a, 33b, on the lower cross member 1.
  • the four knee pads are distributed in two pairs, one of which 20a is located on the side of introduction of the sheet 7 into the machine , that is to say on the upstream side, and the other pair 20b on the outlet side, ie downstream.
  • the upstream-downstream direction will be called the longitudinal direction of the machine, and the one perpendicular to it transverse direction.
  • the sheet 7 brought previously by means of a clamp bar 8 moved to the using a side chain train 10, on a counter-tool 9 located on the lower movable bed base 6, is pressed against the tool 4.
  • the sheet 7 is necessarily placed on the side of the downstream edge of the tool 4 so that the clamp bar 8 is located, at the time of cutting, outside the space between the two bed bases 5, 6.
  • each toggle joint 20a, 20b is mounted vertically movable in a groove or groove 35a, 35b forming a slide and provided in the lower cross member 1. Between each bearing 33a, 33b and the bottom of the slide 35a, 35b is interposed a key 18a, 18b of trapezoidal shape and arranged so that its transverse displacement allows an adjustment in height of the corresponding bearing 33a, 33b, and thus an adjustment of the working pressure, as well as an adjustment of the parallelism of the two bed bases 5 , 6 between them, as already described above.
  • the results of one of these tests are shown.
  • the tool 4 of length AB (or A'B ') is shown schematically in the longitudinal direction and of width AA' (or BB '), as is the sheet of length AC (or A'C ') and of width AA' (or BB ').
  • the length of the tool 4 is 100 cm, that of the sheet 50 cm, while their width is identical and equal to 140 cm.
  • the sheet 7 is therefore half-size relative to the tool 4.
  • the test consisted first of all in establishing, using jacks arranged between the two bed bases 5, 6, a pressure of 3 Mn uniformly distributed over the entire surface of the two working surfaces of the two bed bases 5, 6, the sheet 7, of half format, being arranged in the downstream part of the tool, and then measuring, at different points of the working surfaces, the relative displacement of a bed base with respect to the other.
  • this relative movement is shown vertically.
  • the test was of course carried out at the top dead center of the knee pads 20a, 20b, so as to best simulate the real working conditions of the press.
  • FIG. 2 clearly shows a very strong tilting of the lower face of the upper base 5 relative to the upper face of the lower base 6, this tilting taking place almost only in the longitudinal direction, and not transverse.
  • the basic idea of the invention which has led to the solution of the problem posed above, consists in causing the lower movable bed base 6, during its upward movement, to tilt in a way opposite to that which so far, that is to say, placing the lower base 6, when it is at bottom dead center, inclined relative to the upper base 5 so that when it reaches top dead center, under the effect of the working pressure forces involved, these same beds 5, 6 become parallel to each other.
  • the upper bed frame 5 is equipped with two proximity sensors P1, P2, fixed using brackets 17a, 17b at the bottom of the vertical transverse faces upstream and respectively downstream of this same base 5, this opposite a place of the lower base 6 which is not covered neither by the gripper bar 8, nor by the sheet 7 and neither by the counter-tool 9.
  • the two sensors P1, P2 When therefore the lower movable bed base 6 will be pressurized against the upper bed base 5, the two sensors P1, P2 will indicate exactly the distance between the upstream edges, respectively t downstream, of the two bed bases 5, 6. A comparison of the two values provided by the two sensors P1, P2 will make it possible to define the tilting in question.
  • FIGS. 3 and 4 To make and measure the displacement of the bar 34a, there is provided a motor M1 and a linear position sensor C1, as shown in FIGS. 3 and 4 in which the two upstream keys are also represented schematically (in dashed lines) 18a fixed in a known manner to the bar 34a, as well as the two bearings 33a.
  • the motor M2 and the linear position sensor C2, relating to the bar 34b, are not shown, but replaced by a section along L - L in FIG. 4.
  • the bar 34a is provided at its end ( in principle located on the operator's side) of a threaded part 50 engaged with a corresponding internal thread of a hollow axis 51 rotatably mounted, using a plain bearing 52, inside a bearing 53 fixed, by means of screws 54, to the lower cross member 1 of the frame.
  • the hollow axis 51 is provided with a flange 51c.
  • a first toothed wheel 55, provided with a hub 56, is locked in rotation with the hollow axis 51 by means of screws 70 which pass through the hub 56 and the flange 51c.
  • the hydraulic motor M1 is fixed on a main support 58 using screws 69, the support 58 itself being fixed to the lower cross member 1 by means of screws 59.
  • a second toothed wheel 60 engaged with a gear located inside a free hollow sleeve 61.
  • An auxiliary shaft 63 is rotatably mounted in a corresponding bore of the support 58 and in the extension of the output shaft 57 of the motor M1.
  • a toothed wheel 62 engaged with the internal gear of the hollow sleeve 61
  • a first toothed pinion 64 engaged with the first wheel toothed 55. From FIG. 3 it is possible to see that, by rotation of the pinion 64 by means of the motor M1, in one direction or the other, a corresponding displacement of the bar 34a and therefore of the upstream keys 18a is caused .
  • an auxiliary pinion 65 is also provided, in engagement with the output pinion 64 and mounted keyed on an axis 66 rotatably mounted inside a corresponding bore of the support 58.
  • the axis 66 emerges by a hexagonal part 67 from the support 58 to allow manual rotation drive using a key.
  • the bar 34a In order to measure the displacement and the position of the bar 34a, it is extended (in principle also on the side of the operator, that is to say on the side of its threaded part 50) by a rod 80 passing freely through a corresponding bore executed in the hub 56 of the toothed wheel 55. At the free end of the rod 80 is fixed a plate 81. The end of the output rod 82 of the linear position sensor C1 is fixed in an adjustable manner to the plate 81. The linear sensor C1 is mounted in an adjustable position on an auxiliary support 85 fixed to the main support 58.
  • auxiliary 85 On the support auxiliary 85 are also mounted in an adjustable manner two limit stops 83, 84 which have the function of causing the interruption of the electrical supply of the system in the event that the bar 34a has to move outside the stroke defined by these two stops 83, 84.
  • a graduated ruler 87 fixed on the auxiliary support 85 near the plate 81, gives the operator a first visual approximation of the displacement and of the position of the bar 34a.
  • the setpoint x first passes through a value limiter V working in saturation, then a digital-analog converter D2, a comparator E2 in which the setpoint x is compared at the actual position c2 given by the linear position sensor C2. Their difference c2 is introduced successively into an analog regulator G2 and a control system S2 of the hydraulic motor M2.
  • the motor M2 acts on the reducer R2 constituted in this case by the pinion 64 and the toothed wheel 55.
  • the bar 34b is moved by a distance x2 , as well as the output rod 82a of the linear sensor C2 which, at this instant, will emit a new value c2 of its position, which value will be introduced into the comparator E2 to obtain a closed loop control of the positioning adjustment of the bar 34b.
  • the influence of the output x2 of the reducer R2 is represented by the element T2 symbolizing the dynamics of the mechanical system with delay occurring between the output of the reducer R2 and the proximity sensor P2.
  • the motor control circuit M1 is identical and parallel (see diagram in which the elements relating to the upstream side have the index 1), with the difference however that the position reference value x, before passing through the digital converter- analog D1, is introduced into an intermediate comparator E coming into play when adjusting the parallelism of the two bed bases 5, 6.
  • the cutting force (in MN) is measured using, for example, at least one inductive displacement sensor 12 measuring the relative displacement between a high point H and a low point B of the frame.
  • the sensor 12 is located at the point of the high point H, a rod 13, interposed between the two points H, B being fixed only by one end at the low point B, the other end, free, acting on the sensor 12.
  • Such a measuring device is sufficiently known not to need to be described here in more detail.
  • the adjustment of the parallelism of the bed bases 5, 6 is carried out.
  • the proximity detectors P1, P2 indicate the distances e1 and e2 separating the two bed bases 5, 6 on the upstream side, respectively downstream.
  • These distances e1 , e2, after passing through an analog-digital converter A1, respectively A2, are introduced into a distance comparator Ep.
  • the difference of the two distances e1 and e2 gives the value and the direction of the error of the parallelism e which will be introduced, after passing through a corrector filter F produced digitally on a microcontroller and intended to eliminate random errors, in the parallelism comparator E.
  • a setpoint of parallelism x p is introduced, after passing through a value limiter V1, into the parallelism comparator E.
  • the parallelism error e is compared to the parallelism reference value x p and their difference e p is introduced into the digital-analog converter D1, then in the closed-loop control circuit of the motor M1 regulating the positioning of the upstream bar 34a and therefore of the upstream keys 18a.
  • the parallelism setpoint x p is an infinitesimal value, sensitive to the slightest variations in the operating conditions of the press, the type of work to be carried out and other factors such as those already mentioned above with regard to the pressure adjustment. of work. It suffices here, however, to recall the basic principle already mentioned above, namely that the parallelism x p is chosen so as to cause, at bottom dead center, a relative tilting between the bed bases 5, 6 which is opposite to that measured using proximity detectors P1, P2, at top dead center.
  • the operator can vary the setpoint of parallelism x p taking into account the examination of the cut sheet and previous experience.
  • the successive sheets can be further connected to one another by attachment points, so as to form a strip which passes through the cutting press.
  • the press can have a movable upper bed and a fixed lower bed, as described in patent CH-A-363666.
  • the parallelism errors come from the elongation of the pulls which connect the movable upper bed base to the drive system mounted on a lower cross member of the machine frame.
