Definitions
- the present invention relates to a blanket recovery device for a sheet-like processing machine, a waste disposal station and a sheet-like processing machine.
- the sheets are cut in a matrix corresponding to the developed shape that is desired, for example to obtain a plurality of boxes of a given shape.
- the attachment points between the poses of a sheet are broken and the poses are stacked in vertical stacks in a receiving area where they are separated and stabilized by periodic inset.
- the remaining part of the sheet, also called waste remains pinched in the clips of the gripper bar of the sheet conveyor to be driven to the waste disposal station.
- the clamp bar is driven in the usual way by two loop chains respectively disposed on both sides of the cutting press and to which are fixed the two ends of the clamp bars.

Indeed without the ejection on the fly, to remove the cut sheet of the clamp bar, the machine should for example include an additional waste disposal station in which the clamp bar would stop to deposit the waste sheet . The chain trains should then be extended by an additional bar of tongs, which is expensive and cumbersome.
- Another solution could be to receive a sheet and its poses in the waste ejection station instead that the poses are separated and received in the receiving station. This requires a stop of the machine. The sheet of the clip bar must also be released in order to remove it by means of an additional opening mechanism.

- the sheet driven by the gripper bar 75 is ejected on the fly 92 and tilts on a conveyor belt 93 of the processing machine 1.
- the waste is then for example conveyed by the evacuation belt 93 to a hopper ( Figure 1).

- the curved active profile 17 of the at least one actuating element 3 cooperates with the gripper bar 75 in the active position to open gradually the grippers 76 of the gripper bar 75 at a machine angle, for example between 50 ° machine angle (AM ) and 70 ° machine angle (AM), such as 60 ° AM, so as to allow ejection of a wide range of basis weight of sheets, the machine angle between two successive stopped positions of the gripper bar 75 being equal at 360 ° AM.
- the active curved profile 17 cooperates in opening with the gripper bar 75 from a machine angle ⁇ ° ⁇ , such as 160 ° AM, in Figure 5a to a machine angle ⁇ ° ⁇ + 60 ° AM in Figure 5b.
- the remaining part of the active curved cam profile 17, substantially set back, causes the closing of the gripper bar 75.
- the at least one actuating element 3 is configured to cooperate with a lateral rotational driving element 19 at the passage of the gripper bar 75 and to cause the rotation of an opening axis of the gripper bar 75.
- lateral rotational driving element 19 is arranged at the end of the clamp bar 75, such as at the end of the opening axis of the gripper bar 75. The rotational drive of the opening axis causes the simultaneous opening of all the clamps 76 of the gripper bar 75 and thus the release of the sheet.
- the clamp bar 75 comprises for example two lateral rotating drive elements 19, a lateral rotational driving element 19 being arranged at each end of the opening axis.

- the angle a is the angle formed between the plane of a front portion of a sheet grasped by the clamps 76 of the gripper bar 75 and the horizontal H. The sheet is released from the forceps 76 more or less early depending on its basis weight, a thicker sheet being released later, that is to say for a larger opening of the clamps corresponding to a higher angle.
- the at least one actuating element 3 can be positioned in the path of the gripper bar 75 to start opening the gripper bar 75 when the grippers 76 of the gripper bar 75 form an angle ⁇ between 0 and 10 ° with the horizontal H, such that of the order of 8.5 ° ( Figures 3C and 5A).
- the sheet is thus released when the gripper bar 75 forms an angle ⁇ between 0 ° and 60 ° with the horizontal (FIGS. 3C and 5A) and before the curved active profile 17 completes the opening engagement with the gripper bar.
- 75 for example at a machine angle ⁇ ° ⁇ + 60 ° AM in FIG. 5B.

- This location of the actuating elements 3 makes it possible, on the one hand, to maintain a substantially straight trajectory of the poses sample P that is released, and on the other hand that sample of P poses that had stopped in the separation station 500 poses a little speed so as to take enough energy to be effectively driven as much as possible in a straight line when opening the bar clamps 75.
- the location of the actuating elements 3 and the curved active profile 17 of the cams allow that, when the P-poses sample is released, it does not catch up with the clip bar 75 which precedes it and has sufficient speed not to to be caught by the next clip bar 75 because the sample of poses P ejected flat is in the path of the clip bars 75.
- the at least one actuating element 3 In the inactive position (FIGS. 3A, 3C), the at least one actuating element 3 is positioned apart and does not cooperate with the clamp bar 75 which remains closed as it passes the height of the at least one element actuation 3.

- control member 4 can resume a normal deactivated position, for example after a predetermined number of machine cycles.
- the ejection device 2 may comprise a locking member 5 arranged in the layer separation station 500, configured to prevent the separation of the attachment points of the P-poses sample, by blocking the upper tool 501 of the poses separation tool in the up position.
- the locking member 5 is for example controlled by the actuation of the control member 4, for example on a machine cycle.
- the actuation of the control member 4 may furthermore control, for example, a predetermined number of hole (s) of sheets before the sample of poses P and / or after the sample of poses P, for example two holes of sheets. before and after.
- a leaf hole is made by commanding a clip bar 75 not to pick up sheets in the station of introduction 100.
- the leaf hole before the sheet that is to be sampled makes it possible to move the last piece of sheet-like element away from the evacuation mat 93 (or the first evacuation mat 94 as will be seen later). so that the P poses sample is not placed on a previous waste F. Likewise, the sheet hole following the P-poses sample makes it possible to prevent a successive sheet-like element waste F coming to cover the P-poses sample.
- the blocking of the upper tool 501 and the displacement of the actuating element 3 in the active position are simultaneous on several machine cycles and coordinated with an upstream and downstream leaf hole at the flat ejection of the P poses sample.
- the waste evacuation station 600 may furthermore comprise a device 6 for checking P-pattern samples (FIG. 6).
- the control device 6 comprises an optical monitoring device 7 configured to determine a quality defect of a sample of poses P laid flat on the conveyor belt 93.
- the optical surveillance device 7 comprises for example a camera or a camera.
- the control device 6 may comprise a control unit 8 connected to the optical monitoring device 7, the control device 6 being configured to compare an image taken by the optical monitoring device 7 with at least one reference image to determine the presence of a quality defect.
- the control unit 8 is for example a controller or a microprocessor or a computer of the processing machine 1. This may be the processing unit 13.
- the control unit 8 comprises a memory storing at least one reference image .
- the control device 6 may further comprise an alert unit 9 connected to the control unit 8, the warning unit 9 being configured to generate an alert, such as a warning message or the ignition warning light, to warn the operator if there is a quality defect.
- an alert unit 9 connected to the control unit 8, the warning unit 9 being configured to generate an alert, such as a warning message or the ignition warning light, to warn the operator if there is a quality defect.
- the optical monitoring device 7 thus takes for example an image of the poses sample P laid flat on the conveyor belt 93 and the control unit 8 compares it with at least one reference image to determine the presence or not a quality defect and generate an alert signal in the event of a fault.
- the quality defect may be a cutting defect that has occurred in the processing station 300, such as misalignment of the blank or partial non-cutting or a non-homogeneous cut.
- the quality defect may also be related to print, smudge, tone or color registration defects.
- a quality control can therefore be performed automatically, without requiring the intervention of an operator.
- Regular checks can be scheduled at regular intervals. This visual check is made possible in particular because of the possibility of having a sample of poses P placed flat on a conveyor belt 93 by means of the ejection device 2, and in particular also because the waste of Sheet-shaped elements F are removed from the P-poses sample by the use of leaf holes.
- the waste disposal station 600 may further comprise a P-pattern sample collection device 10 (FIGS. 7 and 8).
- the recovery device 10 instead of a single evacuation belt 93 as previously described, the recovery device 10 includes a first evacuation belt 94 and a second evacuation belt 95.
- the second conveyor belt 95 is arranged following the first conveyor belt 94 relative to the direction of movement of the leaves D.
- the evacuation mats 94, 95 are, for example, like the conveyor belt 93, conveyor belts forming a closed loop around two drums.
- the first discharge mat 94 is fixed.
- the second conveyor belt 95 is movable between a continuous conveying position (FIG. 7) and a raised position (FIG. 8).
- first ends 94a, 95a of the first and second discharge mats 94, 95 are brought together so that the sheet-like elements F can be conveyed from the first conveyor 94 to the second conveyor belt 95 ( Figure 7), then the second conveyor belt 95 to a waste container.
- the first ends 94a, 95a are brought together in a substantially horizontal position but do not touch to avoid friction and allow the second evacuation belt 95 to pivot.
- the first end 95a of the second evacuation belt 95 may be positioned lower than the first end 94a of the first evacuation belt 94 in the continuous conveying position.
- the centers of the drums of the first ends 95a, 94a are for example substantially aligned on a substantially horizontal line, the drum of the first end 94a of the first conveyor belt 94 being larger than the drum of the first end 95a of the second conveyor belt.
- Evacuation 95 This ensures that in continuous conveying position, the waste sheet-shaped elements F are well conveyed from the first conveyor belt 94 to the second conveyor belt 95.
- the second conveyor belt 95 is for example in continuous conveying position when the processing machine 1 is in production.
- the second discharge belt 95 is for example configured to pivot about a second end 95b opposite the first end 95a.
- the recovery device 10 comprises, for example, an actuator, such as a jack, possibly associated with a linkage system for multiplying the action of the actuator, to pivot the second conveyor belt 95.
- the actuator is for example controlled by the processing unit 13, by the actuation of the control unit 4 of the ejection device 2 of the blank samples.
- the second conveyor belt 95 thus pivots, for example, in the raised position on arrival of the at least one sample of poses P on the first conveyor belt 94.
- the first end 95a of the second evacuation belt 95 has pivoted upwards, for example at an angle of between 20 ° and 50 °, creating a gap 11 between the first evacuation belt 94 and the second conveyor belt 95.
- the gap 11 is large enough so that the at least one sample of P poses conveyed by the first conveyor belt 94 can not be conveyed to the second conveyor belt 95, but tilts in the interstice 11, for example to a tray or recovery drawer 12 laying samples P ( Figure 8).
- the waste of sheet-shaped elements F which generally fall back into a state of disarray due to the ejection on the fly, can thus be discharged to the hopper substantially in a straight line (FIG. avoid jams during production and therefore machine stops even when waste sheet-shaped elements F fall in standing or crooked or other.
- the method for taking blank samples 100 comprises the following steps.
- the actuating elements 3 of the ejection device 2 are in the inactive position. They are positioned away from the path of the clip bar 75.
- the sheet-shaped elements are shaped in the processing station 300, the small waste is ejected in the waste ejection station 400, the attachment points between the blanks of a sheet are broken in the separation station poses 500 and the waste sheet-like elements F are ejected on the fly in the waste disposal station 600 at the ejector on the fly 92 and tilt on the discharge belt 93 or on the first Evacuation belt 94 of the recovery device 10 of poses samples (see FIGS. 1, 7).
- the second conveyor belt 95 is in continuous conveying position ( Figure 7).
- the waste F-shaped sheet elements ejected on the fly are conveyed from the first conveyor belt 94 to the second conveyor belt 95 substantially in a straight line, and the second conveyor belt 95 to a waste container.
- the actuation of the control member 4 can trigger, via the processing unit 13, the possible control of a predetermined number of leafholes before the sample of P poses, for example two leaf holes, the locking the upper tool 501, for example on a single machine cycle, the movement of the actuating elements 3 from the inactive position to the active position, for example on a single machine cycle, the one following the machine cycle of the blocking of the machine.
- poses separating tool controlling a predetermined number of sheet holes after the capture of the sample P, for example two leaf holes, the pivoting of the second conveyor belt 95 on arrival of the sample of poses P ejected flat on the first conveyor belt 94 by the ejection device 2 when the processing machine 1 is equipped with a recovery device 10, as well as the taking of an image of the P poses sample laid flat on the conveyor belt 93 or on the first conveyor belt 94.
- a gripper bar 75 captures a sample of P poses (a solid sheet) which is formed in the processing station 300, whose small waste is ejected in the waste ejection station 400, and which stops in the 500. While the P poses sample is cut and cleared of small waste, two bars of clamps 75 do not seize a sheet.
- the upper tool 501 is unlocked.
- the actuating elements 3 are moved to an active position in which they are positioned in the path of the gripper bar 75 (arrow F1, FIG. 3B).
- the actuating elements 3 cooperate with the gripper bar 75 leaving the separation station 500 poses to the passage of the gripper bar 75.
- the actuating elements 3 cause pivoting of the opening axis of the gripper bar 75 to open the grippers 76 and thus eject the laying specimen P on the evacuation belt 93 (FIG. 3C) flat or on the first conveyor belt 94 ( Figure 8).
- the P poses sample is ejected flat, making a movement close to a direct translation in the direction of movement of the sheets D.
- P lay sample is ejected flat at the actuating elements 3 instead of being ejected on the fly at the ejector on the fly 92 as are the waste sheet-shaped elements F in production.
- the sample of P poses can thus be ejected in a "soft" manner, without the attachment points between the poses being broken and without the sheet bending while falling on the conveyor belt 93 or on the first one. drainage mat 94.
- the actuating elements 3 then return to the inactive position away from the path of the rotary drive side members 19 of the clamp bars 75 (arrow F2, FIG. 3C).
- the actuator pivots the second conveyor belt 95 in the raised position on arrival of the at least one sample of poses P on the first conveyor 94, creating a gap 11 between the first conveyor belt 94 and the second conveyor belt 95.
- the at least one sample of P poses conveyed by the first conveyor belt 94 switches in the gap 11 to a tray or recovery drawer 12 laying samples P ( Figure 8).
- the actuator pivots the second conveyor belt 95 in continuous conveying position.
- the control member 4 is deactivated.
- the machine 1 can then resume production (FIG. 3A).
- the operator can thus recover the cut sheet not separated from his poses (or sample of poses P) on the conveyor belt 93 or in the tray or recovery drawer 12.
- the operator can then determine himself by a visual check if the P poses sample has quality defects.
- a quality control can also be performed automatically, without the intervention of the operator by means of the control device 6.
- a quality defect is determined of a P poses sample laid flat on an evacuation belt 93 or on the first evacuation belt 94 by taking an image of the poses sample P laid flat.
