Definitions

  • the present invention relates to gripper bars which, in a machine for working plate elements for the production of packaging, make it possible to pull and position these elements through successive printing, cutting, embossing, upsetting and / or ejecting waste.
  • Such bars are generally attached, at regular intervals and transversely to the direction of travel of the plate elements, to two trains of lateral chains. Inside the machine, these chains make these bars run through a circuit composed, first of all, of successive movements of horizontal translation through the various workstations, then, at the end of the machine, of a directed circular movement upwards towards an upper corridor back to the first station, and finally, in a circular movement downwards towards the starting point, that is to say at the level of the front jogging stops d 'a margin table. There, the clamps are opened by a control device which may, depending on the machine, be an integral part or not of the clamp bar.
  • the mechanism opening of the clamps is operated in the opposite direction, so that the new plate element is gripped by the clamp bar to be taken, during the first translation, in the first work station. Since at each workstation, the plate elements must be stopped in order to be able to execute the corresponding cutting, ejection, etc. operation, these elements must be transferred from a station to the 'other according to successive translations composed of acceleration, deceleration and stop.
  • clamp bars must also be sufficiently rigid so as not to deform when the axis of opening of the clamps, an axis which is an integral part or not of the bar, is driven in rotation against the action of the numerous springs ensuring the closing of the clamps.
  • the rear springs ensuring their closure can only be short and strong to ensure sufficient grip of the plate element. Consequently, the opening torque to be applied to the axis actuating the upper support fingers is high.
  • the clamps are integral with the opening axis, the latter can only be made of steel and highly dimensioned.
  • the bar is currently made from a more or less rectangular tube and appreciable section. Likewise, the attachments of these bars to the chain trains must be of sufficient dimensions. Such a clamp bar is described, for example, in patent FR-A 1178295.
  • Such bars also have the disadvantage of acting, by their weight, on the production rate of the machine.
  • the mobile assembly comprising the clamp bars, their associated fasteners and the two trains of lateral chains to which they are attached, constitutes a mass with a great moment of inertia whose possible accelerations are limited by the resistance capacity of the organs of gripper bars to the stresses resulting from this acceleration, as well as by the power of the main engine.
  • the height of these bars defines the minimum vertical displacement that the lower movable plate must make during the transfer of the plate elements by these bars from one work station to another.
  • the movable stage make the shortest possible displacement.
  • the height of the clamp bars should be minimized, for example, to about the height of the chain trains.
  • the clicking caused by their opening and closing creates a significant noise which must be tried to eliminate.
  • Such bars are generally connected at their two ends to the two trains of lateral chains by means of two so-called “floating” fastening devices so that, on the margin table, the plate element can be exactly positioned and oriented relative to the direction of travel and the workstation.
  • Such "floating” devices described for example in patent DE-C 2520231, generally comprise a connecting element engaged with one end of the clamp bar and elastically connected to the corresponding side chain train. However, this connection is thus designed that, to free the end of the bar from the corresponding connection element, each chain of chains must be spread transversely.
  • the "floating” attachment device comprises a connecting piece connected to the bar and to a special chain train link.
  • the connecting piece is provided with two arms engaged respectively with the outside of the lower and upper walls of the bar, and with two male and female knuckles located one towards the upstream edge and the other towards the downstream edge of the closed off.
  • the special link has a male knuckle.
  • the male and female knuckles are connected together by means of two rods which pass through them by corresponding bores, the male knuckle being mounted on the rods so as to allow a slight movement with elastic take-up in the running direction of the trains of chains. It should be noted that, in this attachment device, the height of the two arms is added to that of the bar.
  • the object of the present invention is to produce a gripper bar whose weight and height dimension are reduced to a minimum, but whose rigidity and gripping force are sufficient to withstand the stresses and forces involved during the operation of the machine. .
  • the clamp bar must also be provided a device for attaching to the chain trains which is simple and light, while allowing easy assembly and disassembly of the bar relative to the two side chain trains.
  • the associated device for opening the clamps must also be lighter and require a lower opening control force while ensuring maximum simultaneous opening of all the clamps.
  • such a clamp bar must allow a reduction in the cost of manufacture and maintenance, as well as a significant reduction in the noise level generated by it in the various workstations.
  • FIG. 1 represents an embodiment of a clamp bar according to the prior art, comprising a hollow hexagonal profile 1, two elastic blades 2, 3, one of which 2 serves as a clamp and the other 3 of counter clamp, located outside and above the upper wall of the hollow section 1 at the downstream edge of which (with reference to the movement of the plate element) they are fixed by means of screws 9 and nut 10.
  • Au upstream edge of the profile is fixed, using a screw 7, an extension bracket 4 on which the free ends of the clamp 2 and the counter clamp 3 come to bear.
  • the clamp 2 is provided with a stud 14 extending through an opening 5 made in the bracket 4.
  • a control member 6, in contact with the stud 14, is provided to open the clamp 2.
  • the clamp bar essentially consists of a bar 100 proper, clamps each comprising an upper finger 110 and a counter clamp 125, of an opening axis of clamps 140 and two attachment devices 165, 169 located at each end of the bar 100 to connect the latter to the side chain trains (not shown).
  • the bar 100 is made from a hollow profile made of aluminum, magnesium or composite material. Seen in cross section, the profile of this bar 100 is trapezoidal with an upper wall 100a, a lower wall 100b and two upstream side edges 100c and downstream 100d converging at 45 ° upwards. The thickness of this bar 100 is approximately 3 mm, except for two inwardly oriented thicknesses, one on the bottom wall 100b close to the center line, the other in the bottom corner of the upstream edge 100c. These extra thicknesses will be used thereafter to accommodate element fixing screws.
  • This profile also has a short horizontal extension 100e extending the bottom wall 100b on the upstream side. In other words, this horizontal extension 100e constitutes a tongue extending over the entire length of the bar 100. Finally, the upstream edge 100c of the bar 100 is pierced, at regular intervals, with windows 112, and the end downstream of the bottom wall 100b is pierced with circular access orifices 116 in correspondence with the windows 112.
  • each of these windows 112 are fixed counter-clamps 125 by means of screws 129 passing through the through orifices 128 of the counter-clamp 125 and of the threads made in the extra thickness appearing at the upstream lower corner 100c.
  • Each counter-clamp 125 in the form of a plate, is composed of two wings inclined relative to one another.
  • a first wing extends horizontally upstream by resting on the upper face of the longitudinal tongue 100e.
  • the other wing inclined at 45 ° relative to the horizontal, comes to rest against the outside face of the upstream edge 100c.
  • the particular fork shape of these counter-clamps 125 is produced by stamping or by molding. This shape is such that, once in place, each counter-clamp 125 is thus supported by the longitudinal tongue 100e.
  • the horizontal flat spout of these counter-clamps 125 has a width of approximately 20 mm and its extreme edge is covered by a strip of vulcanized or glued elastomer 127.
  • the active surface 127 of the counter-clamp 125 is located in the horizontal extension of the lower wall 100b of the bar 100.
  • Each clamp is a steel leaf spring 110, the length, width and thickness of which are approximately 120 mm, 20 mm and 1.2 mm respectively.
  • This same blade 110 is curved at about 60 ° at its first end 110a called the attachment.
  • the blade 110 is bent at 30 ° approximately, then straightened horizontally to be bent again at its end 126 roughly perpendicular to the active surface 127 of the counter-clamp 125.
  • This leaf spring 110 is fixed at its attachment end 110a, slightly bent towards the bottom, on the internal face of the downstream edge 100d of the bar 100 by means of a screw 115 and a nut 120 internal to the bar 100, the latter fixing elements being put in place through circular access orifices 116.
  • the leaf spring 110 passes through the entire interior of the profiled bar 100 in order to emerge from the window 112 and to bear at its support end 126 on the active surface 127 of the counter-clamp 125.
  • the end of support 126 of the leaf spring 110 is rectified to reveal a succession of teeth 126.
  • the teeth 126 press with a certain force on the active surface 127 of the counter clamp 125 l when the screw 115 and nut 120 assembly is tightened to fix the leaf spring 110 in place. It turns out here that the assembly formed by the teeth 126 and the elastomer layer 127 greatly increases the gripping force of the plate element by the clamp bar.
  • the clamp bar 100 is provided with a device for simultaneously opening all the clamps.
  • This opening device comprises an opening axis 140 extending along the axis of the bar 100 and maintained above the internal face of the lower wall 100b of the bar 100 by bearings 142. View in cross section , this opening axis 140 is located about a quarter of the bottom wall 100b of the bar 100 on the upstream side.
  • this opening axis 140 is a hollow tube with thin walls of anodized aluminum and a diameter equal to about 10 mm.
  • the bearings 142 are made from synthetic resin and held in place by screws 146, the head of which penetrates into a housing specially drilled in the excess thickness of the bottom wall 100b.
  • this opening axis 140 passes under each leaf spring 110.
  • a cam 144 is attached by gluing or pinning on the upstream side of the opening axis 140, and this, under each leaf spring 110 respectively.
  • These cams 144 have a length substantially equal to the width of the spring blades 110, ie 20 mm, and a generally square cross section with rounded edges except the left side which, as seen in FIG. 3, has a concave circular line corresponding to the perimeter of the opening axis 140. Since the contact surface between the cam 144 and the opening axis 140 is large, the cam 144 can be simply attached to this axis 140 by gluing or pinning.
  • the length, shape and arrangement of the cam 144 relative to the blade 110 are chosen so as to minimize the torque throughout the opening of the clamp. This limitation is obtained, as can be seen in FIG. 3, by the fact that, during the rotation of the cam 144, the length L1 of the lever arm of the opening torque gradually decreases to compensate for the increase in the force of blade reaction 110.
  • the opening axis 140 emerges from the hollow bar 100.
  • a lever 147 At each end of the axis 140 is mounted a lever 147.
  • means raise the upstream end of the levers 147 to turn the axis 140 anticlockwise by an angle equal to about 33 °, so to cause the lifting end of the spring blades 110 to be lifted to a height of 6 mm by the respective underlying cams 144.
  • This lifting of the spring blades 110 by the cams 144 over such a height is sufficient for the insertion of elements in standard plate in the clamps. Consequently, the limitation of the opening torque of the clamps described above makes it possible to reduce the dimensions of the opening axis 140.
  • cams 144 are not attached along the upstream side of the axis d opening 140 according to a rectilinear generator, but according to a slightly helical generator, so that the clamps located on the ends of the bar 100 are opened first.
  • This arrangement makes it possible to take account of the twist of the opening axis 140, which is only a hollow aluminum tube, during its rotation against the effect of the spring blades 110.
  • the part of the lower face lever 147 coming into contact with control means (not shown) is protected by a layer of elastomer, vulcanized or bonded in order to eliminate noise and reduce wear on the surfaces in contact.
  • Wedges 150 of hardened and hardened steel are fixed by screws inside the bar 100 along the center line of the bottom wall 100b. These shims 150 take up the bending forces acting on the clamp bar 100.
  • the clip bar 100 is connected at each of its ends to a chain of chains (not shown) by a so-called "floating" fastening device shown on the left part of FIG. 2.
  • This device comprises a fastening piece 165 provided with an upstream arm 170a and a downstream arm 170b, both engaged with the corresponding end of the bar 100.
  • the attachment arms 170a, 170b have a shape which exactly matches the outside face of the upstream edges 100c and downstream 100d from the bar 100 to which they are attached using screws 162 placed from inside the bar 100 through the access orifices 116.
  • the size and arrangement of the attachment arms 170a, 170b are chosen so that they do not increase the height of the clamp bar in any way.
  • the attachment piece 165 is also provided with an upstream female knuckle 167a and a downstream 167b.
  • the "floating" device further comprises a male knuckle 169 forming part of a special link 174 of the chain train (not shown).
  • the male 169 and female 167 knuckles 167a, 167b are connected to each other by means of an axis 172 in the form of a rod which passes through them by corresponding bores.
  • the rod 172 In the bore of the male knuckle 169, the rod 172 is surrounded by two sockets 171a, 171b of synthetic resin separated from each other by a spring 180.
  • a first socket 171b, located downstream, is bonded to the internal surface of the 'the bore, while the other sleeve 171a, located upstream, can freely slide in its bore.
  • the rod 172 In the bore of the downstream female knuckle 167b, the rod 172 is surrounded by a stop sleeve 173 acting in relation to a nut 160 engaged with a thread of the downstream end of the rod 172.
  • the upstream end of the rod 172 is provided with a head 172a so that, when the nut 160 is screwed, the rod 172 is fixed longitudinally relative to the female knuckles 167a, 167b.
