Definitions

  • the present invention relates to a device for shifting the lateral position of a tool mounted on a rotating shaft in the notching station within a machine transforming thick or corrugated cardboard plates into boxes.
  • this station performs, in the direction of movement of the plates, a first upsetting operation preparing parallel lines for subsequent folding and a second operation of cutting notches in the upstream and downstream edges of the plate, normally located in the extension of the previously marked lines, which notches define the future folding parts of the box.
  • a drive operation is frequently interposed between the two operations mentioned above.
  • the plate elements pass between pairs of circular tools: an active tool and its counterpart, mounted in correspondence on two horizontal shafts, one upper and one lower, which are arranged transversely to the direction of movement of the elements .
  • the station thus usually comprises three vertical pairs of shafts: a discharge section at the inlet, a middle drive section and a slit section at the outlet.
  • This station also includes mechanisms for moving laterally together each triplet of pairs of tools located along the same line parallel to the direction of movement of the elements, which makes it possible to keep, during adjustments relating to the format of the boxes to be manufactured, the slitting tools in the axis upsetting tools.
  • Each of these mechanisms essentially consists of a master plate for each triplet of upper or lower tools, this plate having on its periphery means for guiding the lateral position of the tools on their respective shafts.
  • a guide means can be, for example, a notch in a semicircle having the effect of a fork coming to engage in the transverse groove of the circular tool which can thus continue to rotate freely driven by its shaft.
  • Another guiding means can consist of a notch in a wider semicircle completed by added fingers or pads which, in turn, engage in the transverse groove of the tool.
  • Other embodiments are also possible, in particular by the use of a protruding wear disc rotating with the tool and caught between two wear pads mounted on either side of the master plate.
  • Each plate is held vertically in the direction of movement of the sheets by at least two shafts: a smooth guide shaft passing through a fork of the plate which is completed by an upper and lower guide block in contact with this shaft, and a threaded shaft passing through a ball nut also integral with this plate. So, by turning thanks to an electric motor the threaded shaft which acts on the ball nut of the plate, it is possible to move this plate laterally, i.e. to the right or to the left, while maintaining it at all points vertical oriented in the direction of movement of the sheets. This plate then simultaneously drives the triplet of upper tools which therefore always remains along the same line. A lower analog device moves the triplet of counterpart tools in correspondence.
  • the upper devices for adjusting the position of the tools require at least one common guide shaft and three threaded adjusting shafts if the Cut shapes have symmetry about the center line of the station, or six individual trees, three coming from each side, otherwise. It is also necessary to provide an identical number of trees for the lower part.
  • a first solution would consist in providing, in the upper part only, for each triplet of tools belonging to the same line, a first device for positioning the upsetting tool only and a second device for positioning the slitting tool and any associated driving tool. This solution would result in doubling the number of guide shafts and threaded shafts thereby increasing the weight of this station, increasing its cost while the corrections are small compared to the initial displacements.
  • the currently selected solution consists in dismantling the active part of the pressure tool from the body fixed on the shaft, and reassembling it by inserting laterally one or more wedges in the form of a transverse disc of standardized thickness.
  • This solution however involves very long adjustment times during the transition from production from one type of box to another. Indeed, after each test, the operator must dismantle the faulty tool or tools to change the shims, then continue his tests until a satisfactory final result.
  • the object of the present invention is a device allowing precise and easy shifting of the lateral position of the delivery tool with respect to the line of action of the corresponding splitting tool, or of the splitting tool with respect to the repressor tool.
  • Such a device must allow a displacement of a large mass over a short distance in a jerky manner so that stopping in the chosen position can be easily achieved.
  • this device must remain simple in design to ensure its solidity and therefore reliability.
  • This station comprises at least tools for upsetting and counterpart mounted in correspondence on a first vertical pair of horizontal parallel shafts arranged transversely with respect to the direction of movement of the plate elements.
  • This station also includes slitting and counterpart tools mounted on another pair of shafts arranged downstream in a manner similar to the first.
  • This station also includes mechanisms for lateral positioning of all the upper tools located on the same line parallel to the direction of movement of the elements.
  • each mechanism essentially consists of a master plate kept vertical oriented in the direction of movement of the elements by at least two transverse shafts: one for guiding and one thread, the latter being able to impart a lateral displacement to the plate, which centerpiece present on his periphery of the lateral guide means of the respective tools.
  • the lateral guide means for a tool to be offset at will relative to the other tools are located on a secondary plate attached to the master plate by mechanical means making it possible to impart a translational movement to this secondary plate. orthogonal to the master plate while keeping it at all points parallel to this same master plate.
  • the mechanical means comprise: - a horizontal pin fixed orthogonally to the master plate and having a vertical transverse orifice, - A metal block secured to the secondary plate, both being crossed by an orifice orthogonal to the secondary plate allowing them to be engaged on the spindle along which they can slide.
  • This block also has a vertical orifice crossing the spindle at its vertical transverse orifice, - a vertical rod, the lower pivot of which is engaged in the vertical transverse orifice of the spindle, the lower part of which is located in the vertical orifice of the block is eccentric cylindrical and the upper part of which ends in a head is held, movable in rotation , to the main plate by a support. So, any rotational movement imparted at the level of the head to the rod results in interaction of the cylindrical part eccentric in the vertical orifice of the block in a lateral translational movement of the block / secondary plate assembly along the spindle.
  • the mechanical means comprise: - a horizontal pin fixed orthogonally to the master plate (or to the secondary plate) - at least one screw othogonally passing through the master (or secondary) plate, the threaded or helical part being located on the side of the spindle, the smooth part being held movable in rotation in the master (or secondary) plate on the one hand by the head and on the other hand by a median shoulder or by a washer.
  • a secondary plate (or master) having a smooth orifice in correspondence of the spindle and a tapped orifice in correspondence of the screw so that, once this secondary plate is engaged on this screw and spindle (or once the spindle and the threaded part of the screw engaged in the corresponding orifices of the master plate), any combined rotation of the screw or screws by action on the head causes an orthogonal translation guided by the spindle of the secondary plate relative to the master plate.
  • the periphery of the screw head has a series of orifices allowing the angular position of the screw to be maintained by means of a ball pushed by a return means out of its housing located close to the head.
  • FIG. 1 a discharge tool 60 on a shaft 40 with its counterpart 75 mounted on a shaft 50. Further downstream, we can observe the right face of the upper drive tool 26 mounted on a shaft 20 Its counterpart as well as the tools further downstream of the slitting are not shown for better clarity of the drawing.
  • a master plate 100 for controlling the lateral position of the upper tools is held vertically oriented in the direction of movement of the sheets by two shafts: a guide shaft 30 and a threaded shaft 10.
  • the shaft guide 30 has been shown in sectioned form. Normally, this shaft is continuous smooth and chrome-plated to allow the guides 110 of the guide fork 105 of the master plate 100 to slide easily along this shaft.
  • Two ball nuts 108 are fixed on either side of the nut 109 of the master plate 100.
  • the threaded shaft passes through these two ball nuts 108, which nuts impose the master plate 100 on its vertical support orthogonal to the threaded shaft 10.
  • these ball nuts transmit to the plate 100 a corresponding displacement to the right or to the left.
  • This master plate 100 has on its periphery several notches in the form of a semicircle having fork effect which engage in a circular groove of the corresponding tool.
  • the fork 107 of the splitting tool and the fork 106 engaged in the upper drive tool are visible in FIG. 1.
  • the fork of the master plate 100 with respect to the the delivery tool is replaced by an enlarged part which does not come into contact with this delivery tool 60.
  • the groove 70 of the delivery tool 60 is engaged by the fork 226 belonging to a secondary plate 225.
  • This secondary plate 225 is carried with its block 220 secured by a spindle 130. This spindle 130 is securely fixed orthogonally to the master plate 100 with respect to the delivery tool 60.
  • the spindle 130 has a vertical transverse orifice 135.
  • the block 220 has a vertical orifice 222 crossing the spindle at the level of the transverse orifice 135.
  • a support 205 is moreover fixed solidly against the master plate vertically spindle 130. This support 205 holds a vertical rod 208 from above, the pivot 210 at the lower end of which is engaged in the orifice 135 of the spindle 130, and the part 209 of which is located inside the orifice 222 of the block 220.
  • This vertical rod 208 is terminated at its upper end by a head 207.
  • This head 207 is provided on the one hand, upstream side, with a handle 212 and on the other hand, downstream side, an extension through which passes a vertical bar of which only the upper button 213 is visible.
  • a return means such as a spring pushes this bar down.
  • this spring can act between a lower shoulder of the bar and the upper face of the housing containing this spring and this bar.
  • This bar can engage in blocking orifices 211 present on the upper face of the support 205, thus blocking the angular position of the head 207 relative to the support 205.
  • FIGS. 2a, b and c The interaction of the eccentric cylindrical part 209 of the vertical rod 208 in the orifice 222 of the block 220 will be better understood on reading FIGS. 2a, b and c having, seen in cross section along the plane II of FIG. 1, the detail of the parts.
  • a pivot 210 engaged in the spindle 130 itself integral with the master plate 100. It is further recognized, sliding along this spindle 130, part of the secondary plate 225 associated with the block 220.
  • the cylindrical part 209 is offset by a distance d relative to the vertical axis of the pivot 210 and the vertical rod 208.
  • the cross section of the orifice 222 of the block 220 is not exactly circular but consists of two semicircles of radius slightly greater than that of the cylindrical part 209, semicircles spaced apart in the direction parallel to the secondary plate by a distance d.
  • the lower edge of this orifice 222 corresponds to the low position of the cylindrical part 209 when the handle is turned completely to the right or to the left.
  • the upper edge of this orifice 222 corresponds to the position of the cylindrical part 209 when the lever 212 is parallel to the secondary plate 225 as illustrated in FIG. 2b.
  • any action on the handle 212 after lifting of the button 213 results in a rotation of the vertical rod 208 around the pivot of the 210 and inside its support 205.
  • This rotation of the rod 208 implies a rotation of the cylindrical part 209 pushing on one side or the other the block 220, therefore moving the secondary plate 225 relative to the master plate 100.
  • the operator usually accomplishes this rotation up to '' to be able to re-engage the bar in a new orifice 211 of the support 205.
  • This lateral displacement of the secondary plate 225 has induced a similar displacement of the discharge tool 60 by the engagement of the fork 226 inside the groove 70.
  • the counterpart 75 being sufficiently wide with respect to the small printed offset, it is not necessary to reconsider its position.
  • FIG 3 is illustrated in perspective a second embodiment of the device according to the invention. Parts similar to those described above bear identical references.
  • a discharge tool 60 carried by the shaft 40 and its counterpart 75 carried by the shaft 50.
  • the master plate 101 is held vertically in the direction of movement of the plate elements by a guide shaft 30 and a threaded shaft 10 acting on the nut 109 through two ball nuts 108.
  • two other modes of lateral tool guiding by the master plate 101 namely: guiding the driving tool 28 and the slitting tool 124.
  • the tool 28 has a projecting circular disc 27 caught between two wear pads 120 located on either side of the plate 101.
  • the tool 124 has a transverse circular groove 127 similar to the groove 70 of the tool 60. But in this case, the notch 125 in the form of an arc of a circle of the master plate 101 is widened, and these are two drive fingers 126 fixed on the periphery of this notch 125 which engage the tool 124 in the groove 127.
  • the advantage of these other modes of guidance is that the parts which can wear during operation can be replaced.
  • the secondary plate 325 is connected to the master plate 101 by a pin 131 and a screw which are horizontal and parallel to each other.
  • the pin 131 passes orthogonally through the secondary plate 325 where it is secured by wedging or welding, and it enters a corresponding orifice arranged in the master plate 101 in which it can slide.
  • a reverse arrangement can also be envisaged: that is to say a spindle 131 secured to the master plate and a secondary plate 325 then sliding along this spindle.
  • the screw passes through the secondary plate 325 in its smooth part 140.
  • This smooth part 140 is held axially in the master plate, but movable in rotation, by a shoulder or washer 144 on the side of the master plate and a head 141 on the other side.
  • the threaded part 145 of this screw is engaged in a tapped orifice in correspondence with the master plate 101.
  • the head 141 is also completed on its periphery by a handle 147 and by a series of semi-spherical orifices. Close to this head 141 is a housing containing a spring 143 pushing out of this housing a small ball 142, which ball enters one of the orifices of the head 141. This device of orifices and ball makes it possible to index the angular position of the screw.
  • the screw can be turned which, by feedback from the threaded part 145 in its tapped hole, moves to the right or the left according to the direction of rotation printed by taking with it the secondary plate 325 due to the presence of the shoulder 144 and the head 141. No jamming is possible given the larger diameter of the spindle 131 and the excess thickness of the secondary plate at this level .
  • the spindle 131 is replaced by a second screw, the threaded part of which enters a second orifice tapped in correspondence in the master plate, and the head of which is held longitudinally in a manner movable in rotation by the secondary plate.
  • a displacement device allows the screw to be driven by the first.
  • the means for guiding the delivery tool 60 by the secondary plate is in the form of a semi-circular fork directly engaging the groove 70 of the tool. Obviously, this means is in no way limiting and it is easy to adapt the other guide means previously described on this secondary plate 325.
  • this shift device significantly reduces the downtime of the machine during a transition from production from one type of box to another.
  • the operator can adjust this offset to 1 / 8th, 1/4 or half the width of the split.
