Definitions

  • the invention relates to a separator for the transient reception of plate elements according to claim 1.
  • the invention relates in particular to a station for receiving plate elements and discharging packs of plate elements for a packaging manufacturing machine according to claim 11.
  • plate elements After undergoing various printing or converting operations, plate elements must be stacked in packs in a predefined number and with precise positioning of the plate elements between them. Downstream of converting machines, it is thus known to use a plate element counting station, a station for stacking the plate elements on a lifting table, and a system for transferring a stack to an output conveyor to separate the stacks.
  • a free-fall stacking station includes a lifting table.
  • a device drops the plate elements sequentially onto the lifting table, to form a stack.
  • the lifting table descends at the growth rate of the stack. Once the number of plate elements corresponding to a package is reached, the problem arises of correctly evacuating this package without interrupting the plate element feed cycle.
  • the document EP 0501213 describes a station for stacking, separating and discharging packs of plate elements.
  • the station comprises means for feeding the plate elements, retractable supports forming a temporary stacking magazine, placed above a pack discharging device.
  • Such a station has disadvantages.
  • the first plate element arriving in the stacking magazine will be in contact with, and be damaged by, the retractable supports.
  • the stacking magazine temporary will be saturated more quickly with plate elements arriving at high speed, which limits the overall productivity of the printing or converting line.
  • the document EP 0666234 describes a stacking, separating and evacuating station for packs of plate elements.
  • the station comprises a vertically movable lifting table, receiving plate elements falling to be stacked.
  • the table gradually descends to the level of an output conveyor, recovering and evacuating a pack of plate elements after its formation.
  • a separator moves vertically and horizontally. After the formation of a pack, the separator comes to overhang the lifting table and then comes to interpose itself to support the plate elements of the next pack.
  • the lifting table then transfers the pack just formed, towards the output conveyor which evacuates the pack.
  • the separator is then retracted and the lifting table can then recover the plate elements of the next pack.
  • Such a station has disadvantages.
  • the separator has a certain inertia. Its movement during a cycle proves difficult to achieve at a speed compatible with the stacking rates required for the plate elements.
  • Such a separator may also prove incompatible with certain methods of transverse alignment of the plate elements.
  • Document US5882175 discloses a stacker for stacking sheets or blanks of cardboard for use in the manufacture of corrugated cardboard containers.
  • a first and second set of fingers are arranged alternately and constitute a continuous loading surface.
  • US2013/140763 discloses a non-stop stacking device comprising a plurality of rods attached to a guide member.
  • US2015/050113 discloses a machine provided with a device for temporarily receiving sheets.
  • the device comprises a plurality of bars parallel and movable.
  • US7402130 discloses a system for separating, folding, stacking and transporting a continuous web without interruption.
  • the system includes a temporary support that allows a new stack to form before a previous stack has been evacuated.
  • JPH03115056 discloses a stacking device comprising two cooperating members and configured to support a stack being formed.
  • the invention also relates to the following variants.
  • the clutch device of each arm includes a cylinder configured to move in translation the pinion associated with the arm along the axis of the shaft, to selectively engage or disengage it from the rack of the arm.
  • each of the cylinders drives a lock immobilizing the translational sliding of the associated arm when the pinion associated with the arm is disengaged.
  • the pinion is coupled to the shaft by means of a key.
  • the arm comprises a slide cooperating with a slide secured to the support, so as to guide the movement of the arm in the longitudinal horizontal direction.
  • the arms are arranged at the same vertical level relative to the support.
  • the arms are slidably mounted relative to the support so as to be able to reach a cantilevered length for holding a bundle of plate elements relative to the support of said first side.
  • control unit is configured to control the downward sliding of the support by a succession of sliding steps and stops.
  • the invention also relates to a station for receiving plate elements and discharging packs of plate elements for a packaging manufacturing machine, comprising a separator as described above.
  • the longitudinal direction is defined by referring to the direction of travel or drive of the plate elements in the packaging manufacturing machine, in the plate element receiving station, along their median longitudinal axis.
  • the transverse direction is defined as the direction perpendicular in a horizontal plane to the direction of travel of the plate elements.
  • the upstream and downstream directions are defined by referring to the direction of movement of the plate elements, following the longitudinal direction throughout the packaging manufacturing machine, from the machine inlet to the machine outlet and the plate element receiving station.
  • THE Figs. 1 And 2 are perspective views of an exemplary separator 1 according to an embodiment of the invention.
  • the separator 1 is intended to ensure a transient reception of plate elements to be transferred from a lifting table to a conveyor for outputting packages of such plate elements (detailed later).
  • the separator 1 can thus be included in a station for receiving plate elements and for discharging packages of these elements, for example for a packaging manufacturing machine.
  • the separator 1 comprises a frame 18, a support 10, a drive device 11, a drive system 12, arms 13 and a control unit 19.
  • the support 10 is mounted to slide relative to the frame 18 in a vertical direction.
  • the frame 18 comprises two vertical uprights 180 (direction Z illustrated) and a transversely oriented crosspiece 181 connecting the vertical uprights 180.
  • the support 10 can be guided in vertical sliding in a manner known per se by vertical rails that can be arranged in the uprights 180.
  • the support 10 forms an elongated beam in a transverse direction (direction Y illustrated).
  • the transverse direction is horizontal and perpendicular to the transport direction (direction X) of the plate elements reaching the separator 1.
  • the drive device 11 is configured to drive the support 10 in the vertical direction.
  • the drive device 11 here includes an electric geared motor 110 controlled by the control unit 19, and belts 111 engaged with a rotor of the geared motor 110 via a shaft 112 on the one hand, and engaged with the support 10 secured to a fixed point on each of the belts 111.
  • the belts 111 are guided by toothed pulleys 113.
  • the motor is here fixed to the crosspiece 181.
  • Arms 13 extend in the longitudinal horizontal direction and are spaced apart from each other in the transverse direction.
  • the arms 13 are mounted on the support 10 so as to be guided in their movements in the longitudinal horizontal direction.
  • the movement of each of the arm 13 modifies its cantilever length relative to the support 10, in particular on a first side relative to the support 10 in this horizontal direction.
  • the cantilever of the arms 13 relative to the support 10 can for example be measured relative to a plane including the directions Y and Z and positioned at a longitudinal end of this support 10.
  • the arms 13 are positioned on a second side relative to the support 10 and have a minimum or zero cantilever value on the first side relative to the support 10.
  • the drive system 12 is configured to simultaneously move one or more arms 13 in the longitudinal horizontal direction and to maintain one or more other arms 13 in their longitudinal position.
  • the drive system 12 here includes a shaft 15 extending in the transverse direction and guided in rotation by the support 10, for example by various bearings and ball bearings not detailed.
  • the drive system 12 further comprises an electric geared motor 120, driving the shaft 15 in rotation.
  • the drive system 12 further comprises a respective toothed pinion 150.
  • Each of the pinions 150 is rotationally integral with the shaft 15.
  • the drive system 12 further comprises a rack 130 integral with this arm 13.
  • the drive system 12 further comprises a clutch device 14 (detailed later) configured to selectively couple and uncouple a pinion 150 and a rack 130.
  • Fig. 3 is a perspective view of the separator 1 at the level of the drive system 12 and of a clutch device 14 for an arm 13.
  • the Fig. 4 is a sectional view at the level of the drive system 12 and of this clutch device 14.
  • the arm 13 here comprises a slide 131.
  • the slide 131 cooperates with a slide 100 of the support 10, so as to guide the movement of the arm 13 in the longitudinal horizontal direction.
  • the pinion 150 is mounted sliding in the transverse direction (corresponding to the direction of the axis of rotation of the shaft 15) relative to the shaft 15.
  • the pinion 150 is coupled to the shaft 15 by means of a key 151.
  • the pinion 150 is thus movable between two transverse positions: the position illustrated in Fig. 4 in which it is engaged with the rack 130 of an arm 13, and a position further offset to the left, in which it is uncoupled from the rack 130.
  • the clutch device 14 of each arm 13 here includes a jack 140.
  • the body of the jack 140 is fixed to the support 10.
  • the jack 140 is controlled by the control unit 19, so as to move its piston 142 in the transverse direction.
  • the piston 142 is able to axially move the pinion 150.
  • a flange 153 is thus fixed to one end of a sleeve 154 integral with the pinion 150 and coaxial with the pinion and the shaft 15.
  • the flange 153 is engaged with a fork 152 which is fixed to the free end of the piston 142.
  • the flange 153 is thus slidably driven by the piston 142 in the transverse direction.
  • the movement of the piston 142 selectively allows the pinion 150 to be coupled or uncoupled relative to the rack 130.
  • the rotation of the shaft 15 does not drive the arm 13 in translation.
  • the separator 1 comprises a locking mechanism, making it possible to immobilize an arm 13 in translation, when the latter is not driven by the device 12.
  • a stud 141 projects in a transverse direction relative to the flange 152.
  • the stud 141 is positioned opposite a bore 132 formed in the arm 13.
  • the piston 142 uncoupling or disengaging the pinion 150 and the rack 130, the stud is driven until it is housed in the bore 132.
  • the stud 141 then makes it possible to immobilize the arm 13 in translation.
  • the longitudinal movement of the arms 13 is used to form a transient support for plate elements.
  • the arms 13 are thus deployed to form a receiving grid, so as to transiently receive the plate elements in the form of a package, the arms 13 being arranged so as to be able to cross (without interfering) endless conveyor belts of a lifting table in the vertical direction.
  • the inertia of movement of such arms 13 is significantly less than the inertia of the entire separator 1 if it were necessary to move it.
  • the arms 13 are slidably mounted relative to the support 10 in order to be able to reach a cantilevered length, making it possible to hold a bundle of plate elements relative to the support 10, on a side corresponding to the arrival of these plate elements.
  • these arms 13 are advantageously all arranged at the same vertical level relative to the support 10.
  • the arms 13 are spaced apart from each other in the transverse direction by a distance corresponding to a spacing between endless conveyor belts of a lifting table detailed later.
  • the arms 13 can thus be intersected with such conveyor belts.
  • the control unit 19 is configured to control the drive device 11, so as to position the support 10 at an appropriate vertical position.
  • the control unit 19 is also configured to select the arms to be moved towards a lifting table and the arms to be maintained in a retracted position relative to the lifting table.
  • Fig. 5 is an exploded perspective view of the association of the separator 1 with a lifting table 2.
  • the Fig. 6 is a top view of a combination of the lifting table 2 and the separator 1.
  • the Fig. 7 is a side sectional view of the combination of the lifting table 2 and the separator 1.
  • the Fig. 8 is a front view of the combination of the lifting table 2 and the separator 1.
  • the frame 18 of the separator 1 is fixed to a frame of the lifting table 2.
  • the lifting table 2 comprises endless conveyor belts 20, mounted on a support 23. These endless conveyor belts 20 are configured to be able to drive plate elements in translation in the longitudinal direction, common to the longitudinal direction of the separator 1.
  • all arms 13 are cantilevered on the side of the lifting table 2.
  • a suction device 22 for plate elements can be distinguished, configured to selectively retain or release a plate element. The plate element then falls by gravity either onto the arms 13 of the separator 1 or onto the endless transport belts 20 of the lifting table 2.
  • the plate element receiving station comprises jogging stops or joggers 21, arranged transversely on either side of the plate elements 9.
  • the joggers 21 make it possible to set the transverse position of the plate elements 9, in order to form a bundle 90 with well-aligned elements 9.
  • the main function of engaging and disengaging the arms is not to select the arms which are out of width and which would then strike the lateral joggers 21.
  • the arms 13 in the retracted position make it possible to avoid any risk of collision with such joggers 21.
  • Such a separator 1 further allows arms 13 to be selectively disengaged or engaged, which makes it possible to deploy only the necessary number of arms 13 to receive plate elements of a given width (or width).
  • the inertia of the drive of the arms 13 can thus be reduced, for a separator 1 having to execute cycles of a reduced duration.
  • maintaining a certain number of arms 13 in the retracted position makes it possible to reduce the pivoting torque about the transverse axis for the support 10.
  • Fig. 8 is a front view of the combination of the lifting table 2 and the separator 1.
  • the arms 13 of the separator 1 are here at the same level as the endless transport belts 20.
  • the deployed arms 13 are interposed between endless transport belts 20.
  • the lifting table 2 and the separator 1 can be associated downstream of means for supplying the plate elements 9 successively one after the other.
  • control unit 19 controls the downward sliding of the support 10 with a succession of sliding steps and stops.
  • the arms of the support 13 are in the deployed position above the lifting table 2, and in particular above the suction device 22.
  • the arms 13 are held in the deployed position above the suction device 22.
  • Plate elements 9 have been stacked on the endless conveyor belts 20.
  • the support 23 is gradually lowered as the plate elements 9 are stacked.
  • the arms 13 were brought into the retracted position, then the support 10 was lowered below the level of the suction device 22. Arms 13 were then deployed under the suction device 22 (for the sake of simplification, all the arms were here deployed), and above the support 23. The arriving plate elements 9 are then stacked on the deployed arms 13 of the separator 1. The plate elements 9 positioned on the endless conveyor belts 20 can thus be moved, while the cycle of arrival of new plate elements 9 continues.
  • a package 90 present on the endless conveyor belts 20 is transferred by them onto the output conveyor 3.
  • the support 10 gradually descends with the stacking of plate elements 9 on the deployed arms 13.
  • the output conveyor 3 evacuates the package 90.
  • the support 23 then rises up to the level of the arms 13.
  • the endless conveyor belts 20 then come to be inserted between the deployed arms 13 until they come to support the stack of plate elements 9.
  • the separator 1 thus made it possible to ensure the transient reception of plate elements 9, making it possible to separate different packages of elements and making it possible to ensure their transfer to the output conveyor 3.
  • the deployed arms 13 no longer support the stacking of the plate elements 9, which are now supported by the endless conveyor belts 20.
  • the arms 13 then initiate a movement towards their retracted position.
  • the arms 13 have all been moved to their retracted position. None of the arms 13 are then cantilevered above the lifting table 2. The arms 13 are then retracted out of the travel of the support 23 of the lifting table 2.
  • the support 10 has been raised up to above the suction device 22.
  • the arms 13 have been advantageously moved in a cantilevered manner above the suction device 22, so as not to risk interfering with an operator vertically above the output conveyor 3.
