Definitions

  • the present invention relates to a station for stacking, separating and evacuating batches comprising a predetermined number of stacked plate elements, such as sheets of paper or cardboard, or flattened cardboard boxes, said station being located downstream of a counting and feeding station of said elements leaving a processing machine.
  • the sheets are advanced successively along a distributor conveyor in front of a counting device, including for example a photoelectric cell, to the stacking station comprising a collecting device, such as a hopper, in which the leaves are staked in a regular pile.
  • a collecting device such as a hopper
  • Some form of mechanism is required to adapt the growing stack to the collector.
  • a known mechanism allows the conveyor to be lifted in close connection with the growing pile, while the most typical mechanism known as "free fall" forces the leaves to land on a table with alternating vertical movement which descends at the speed of stack growth.
  • the stacking station of this type described in document FR 2 34 882 comprises a plurality of parallel L-shaped fingers forming a separator normally arranged horizontally and mounted in rotation at one of its ends on a mobile carriage, this separator being designed to temporarily accommodate sheets falling over a previous batch being evacuated by a transporter.
  • the station further comprises a second plurality of parallel T-shaped fingers joined by a rod thus forming a table which can be moved vertically through the conveyor to support the sheets temporarily stacked on the separator and deposit them on the conveyor while the separator withdraws in order to adopt an oblique attitude and returns to the waiting position above the stack being built up on the conveyor.
  • the separator collapses to collect the following sheets.
  • the maximum number of sheets that can belong to the same batch depends on the maximum lifting angle of the separator, which is necessarily small given the mechanical stresses generated.
  • the station described in document FR 2 445 563 comprises a hopper closed at the bottom by a vertically movable table and on which squared sheets accumulate.
  • a rear finger is placed on the batch to separate it from the following sheets and descends in combination with the table until it arrives at an evacuation conveyor.
  • a pusher then moves the batch laterally towards the conveyor, the upper sheets being held back by the finger, forward by the batch, while the pusher is withdrawn and the table rises to support these upper sheets.
  • a second finger movable vertically in parallel with the first is already in the waiting position to separate the next batch.
  • the table must necessarily have a surface area smaller than that of the sheets.
  • this station involves a complex device for displacement in phase opposition of two separating fingers.
  • the leaves accumulate on a pile supported by a table movable downwards inside a hopper.
  • an interrupt plate or bar advances from the front of the hopper a short distance over the top of the stack.
  • the table supporting the battery continues to move downward relative to the switch so that a vacuum is created in which support arms are inserted.
  • the switch can then be removed and the arms support the accumulation of subsequent leaves.
  • the batch is lowered by the mobile table onto a conveyor belt with evacuation.
  • the empty table then rises and, passing between the support arms, lifts the new stack.
  • the arms can then be removed pending a new cycle.
  • the control mechanism of the interruption plate proves to be quite complex in coordination with the movement of the support arms.
  • the document EP 0 529 708 describes a stacking station provided more particularly for cardboard boxes laid flat at the end of folding and gluing, but some legs of which are liable to rise.
  • the sheets brought by the upstream distributor conveyor are launched into the hopper against the front stops, and this by two horizontal and parallel ejector rollers in a vertical rear plane. Leaves fall squarely on top of a pile forming on a table elevator which descends as this stack is created.
  • a separator located at the front of the hopper, produced in the form of a plurality of forks assembled by a movable cross member along a first vertical rack and a second horizontal rack, comes land on top of the lot to receive the next sheets.
  • the table then descends to the level of an evacuation conveyor on which the batch is transferred by a pusher.
  • the empty table then rises to take charge of the new battery which has already accumulated on the separator having descended as much as necessary.
  • the separator retracts in translation forward, then rises to its standby position at the level of the ejector rollers.
  • the front stops are mounted together on a horizontal screw allowing their position to be adjusted according to the format of the boxes to be received.
  • the device for driving the separator along racks can only be of low power, leaving this separator only a passive role of guide.
  • This station then requires the use of a pusher powerful to evacuate the batch of boxes, which always constitutes a slow, heavy and expensive organ present in excess in the station.
  • a plurality of flexible cams is rotatably mounted on an axis located at the height of the ejector rollers, these cams regularly striking the rear edge of each box to push it towards the stack.
  • this device and these coordination means are very complicated for the little effect obtained.
  • the aims of the present invention is a stacking, separation and evacuation station for batches of stacked plate elements of the "free fall" type like those described above, but which ensure, for high speeds, better reliability of the quality of the batches delivered, in particular by optimizing, even simplifying, the constituent bodies.
  • rollers or the rollers or the endless belts composing the path on the top of the table are motorized, or, alternatively, if the roller or endless belt paths composing the path on the table top are crazy but that the table is capable of integrating into a motorized evacuation conveyor located at the start of the exit conveyor, then, by coordination of the upper and lower drive means, a release force of a particularly powerful batch is obtained and balanced which makes it possible to envisage remarkable accelerations, therefore cadences unknown to date.
  • the means for guiding the cross-member-separator comprise at least one first carriage integral with the cross-member and movable in sliding along a first axis of displacement parallel or perpendicular to the plane of the table, this first axis being integral with a second mobile carriage sliding along a second axis of movement perpendicular to the first axis.
  • the lifting table as well as the separators and the outlet conveyor are inclined towards the rear by an angle of between 5 and 15 degrees and preferably of the order of 10 degrees.
  • the temporary front supports include a plurality of parallel fingers, each advanced or retracted directly by its actuator.
  • the rear temporary supports include a movable plate tilting about a horizontal axis and a rear leg of which is connected to an actuator.
  • the station further comprises one or more hanging pressers, mobile in rotation, with a transverse axis carried at each end by supports, this or these pressers pressing on the last plate element coming then resting on top of the battery.
  • hanging pressers mobile in rotation, with a transverse axis carried at each end by supports, this or these pressers pressing on the last plate element coming then resting on top of the battery.
  • the angle pulleys and the deflection wheel of the drive means of the separator-carrying cross member belonging to the same side are respectively mounted on two identical longitudinal plates and held parallel to one another by cross members, the position of these plates that can be simultaneously modified along a side member of the station frame to easily take into account the format of the sheets or boxes of each production series.
  • the station according to the invention firstly comprises a frame formed by a pair of rear lateral uprights 12 and a pair of front lateral uprights 14, these uprights being connected by upper side rails 16.
  • the rear uprights 12 are located upstream relative to the direction of movement of the production, and on the right side of Figure 1; while the front uprights 14 are located downstream, that is to say on the left-hand side of FIG. 1.
  • ejector rollers 22, 24 are disposed front stops 30, also visible in FIG. 2b, in the form of substantially vertical plates fixed to the same beam 36.
  • This beam is hung on either side to the side members 16 by means of carriages 35 sliding on rails 18 of the longitudinal members thus allowing a depth adjustment of the position of these stops according to the length of the plate elements 20.
  • pressers 80 which, as best seen in FIG. 2a, are hung movable in rotation on a horizontal axis held on either side by supports 82.
  • these supports 82 are connected to the side members 16 by carriages 84 sliding in the rail 18 also allowing a depth adjustment of their position.
  • these elements 20 are squared at the front by the stops 30, at the rear by a stop 32 and from the side by lateral stops 34, these last two members being better visible in FIG. 3a.
  • the lateral position of the stops 34 can be adjusted by action on adjusting screws 31.
  • the elements 20 thus accumulate in a very regular stack on the table 60. This table descends as the increase in pile so that the drop height of the following elements remains substantially constant.
  • the station comprises a device for separating lots 21 of elements stacked in predetermined number in the form of a plurality of separators 70 connected at their front end to a single horizontal cross member 79 separators.
  • These separators are in the form of bars flattened in the vertical direction and having, in horizontal section, a slightly conical shape oriented towards the rear.
  • the cross-member 79 separator carrier is driven at each end by a chain or belt 73 defining its movement path.
  • the cross member 79 is integral of one or more carriages 76 movable in sliding along a first substantially vertical displacement axis 71, this axis being itself integral with a horizontal carriage 72 mobile, also in sliding, along a second axis of substantially horizontal movement 19.
  • the separators 70 remain constantly parallel to the plane of the table 60.
  • the chain 73 causes the separation member to traverse a vertical translation behind the stops 30, then a lower translation forward followed by an upward return around a deflection wheel 74 finished by an upper rearward translation, before reaching a waiting position at an upper angle wheel 77.
  • the upper and lower angle wheels 77 as well as the reference 74 are mounted, on each side of the station, on a longitudinal plate 78, these two side plates being interconnected by several crosspieces 15, 15 '.
  • the plates are themselves connected to the spar 16 through carriages 17 capable of sliding along the same rail 18 in order to allow the depth position of the separators to be adjusted as a function of the format of the plate elements.
  • the horizontal movement axis or axes 19 of the carriage 72 are held between two upper crosspieces 15.
  • the output pulley of a motor 86 mounted between the plates 78 is connected by a chain or drive belt 87 to an external pulley 89 secured to a transmission shaft 88 carrying, opposite each of the idler wheels 74, a drive pulley 89 '.
  • These idler wheels 74 can thus be driven by chains or belts drive 75.
  • the drive separators 70 is thus both powerful and balanced on each side.
  • the lifting table 60 is capable of descending to the level of an output conveyor 94 of the lots constituted 21.
  • This output conveyor 94 begins, upstream, by a motorized evacuation conveyor 90 which, if desired, can be in the form of a conveyor belt 90 'in the middle of which can descend the lifting table 60 then composed of a plurality of roller tracks.
  • An upper roller ramp 92 is disposed above the outlet conveyor 94 and applies a pressing force on the top of the lots 21.
  • This ramp 92 is connected at its rear end to the lower part of the front stops 30, such that 'illustrated in Figure 3b, and in its front part to a crosspiece of the frame better visible in Figure 1.
  • the station includes a plurality of temporary supports 45 in the form of fingers, each advanced or retracted directly by an actuator 46 arranged in their forward extension.
  • an actuator 46 arranged in their forward extension.
  • rear temporary supports 40 on the rear uprights 12.
  • this temporary support 40 is presented in the form of a plate mounted in rotation about an axis 41 so that it can be tilted forward under the action of an actuator 42 illustrated in Figure 1 and connected to a rear leg of the plate 40.
  • Figure 4a illustrates the station when starting the stacking of a first batch.
  • the separators 70 are then in the high standby position while the elements 20, launched by the rollers 22 and 24 against the front stops 30, fall on a pile forming on the table 60 initially in the high position.
  • FIG. 4b illustrates the moment when the separators 70 are lowered on the top of the stack at the moment when a batch is counted down, and this to receive the following elements.
  • the separator 70 and the table 60 then descend simultaneously, the separator applying a holding pressure on the batch formed.
  • FIG. 4c illustrates how the separators 70 are found at the lower end of the front stops 30, that is to say at the level of the temporary supports before 45, when the table 60 has arrived at the motorized evacuation conveyor 90 Due to the conical shape given to the horizontal section of these dividers, a free space is created between the batch and the following elements, space in which the supports can advance without effort 45.
  • FIG. 4d illustrates the major effect of the invention, namely that the batch can be pulled by the separators 70 acting horizontally on top of the batch thanks to the friction forces resulting from the vertical pressure applied.
  • the motorized conveyor 90 comes into action simultaneously, thereby enabling particularly rapid and balanced evacuation. From the start of the movement of this lot, and while it still supports the upper sheets, the rear temporary support 40 switches to a horizontal position, its upper elements then being entirely isolated.
  • FIG. 4e illustrates how, when leaving the batch, the empty table immediately rises towards the new stack being formed, while the separators 70 pass from bottom to top around the idler wheel and then carry out their upper translation.
  • FIG. 4f shows how the front 45 and rear 40 supports could have been retracted as soon as the table 60 took charge of the new stack, this table then recommencing its descent as the accumulation progresses.
  • the batch once constituted is systematically held firmly below and above by organs during its evacuation, which can thus be carried out very quickly even if this movement involves brutal accelerations.
