Definitions

  • the present invention relates to a vibrating table for receiving sheet articles, in particular bundles of sheets of paper.
  • the bundles, or forms made up of sheets of the same format, or of format and / or of different nature, made up by an assembly machine known per se, are at the exit of this one stacked on a vibrating table with plan inclined adapted to allow the equalization of the articles in sheets and thus to allow the formation of a regular stack (US-A-3,772,972).
  • the thickness of the stack cannot exceed a determined threshold and the number of bundles contained in the stack formed on the vibrating table finds it limited.
  • the present invention relates to a vibrating table which allows the abovementioned drawbacks to be eliminated.
  • the subject of the invention is a vibrating table for receiving sheet articles, in particular bundles of sheets of paper, with a view to stacking them in a stack-forming zone, of the type comprising a detection member sensitive to a characteristic size of a pile being formed, this vibrating table being characterized in that a discharge zone is provided next to the pile formation zone, and in that it comprises a controlled transfer device by said detector member so as to move said stack from the stack forming area, to the discharge area, when said characteristic quantity reaches a predetermined value.
  • the detection member controls the transfer device so that it drives the stack formed outside the movable parts of the assembly machine to the evacuation zone where it must be evacuated.
  • the vibrating table according to the invention solves in a simple manner the problems posed until now in particular in the field of the performance of assembly machines, perforators, or the like concerning the making of works such as bundles, forms and others.
  • a vibrating table according to the invention indicated as a whole by 10 is in particular intended, although not exclusively, to be placed at the end of an assembly deck 11 of a assembly machine having a distribution assembly 12 comprising for example three distribution stations 11A, 11B, 11C, on each of which is placed a stack of sheets F which may be of a format, and / or of a nature different from a station to the other.
  • a handling device 13 is placed capable of removing the sheets from each of the stations one by one, and placing them on the abovementioned assembly deck 11.
  • the vibrating table is supported by a frame equipped with means suitable for printing vibrations, said vibrator means not being shown here because they are known per se; it comprises a plate 20, quadrangular, with on its upper face respectively a front stop 21 and a longitudinal stop 22 forming between them an angle of 90 °, and which are perpendicular to the plane of the plate.
  • the tray 20 On its underside, the tray 20 is provided with means capable of supporting a transfer device generally indicated at 25 suitable for transporting a stack of sheets, or bundles, formed in the area of stack formation ZF, towards a discharge area ZE spaced from the previous one, said zones being in the example shown one after the other in the extension of the assembly deck 11 of the assembling machine.
  • Such a transfer device is for example carried by a chassis C (partially shown in Figures 2 to 5) arranged on the underside of the plate 20; this transfer device comprises claws 26 fixed to a movable carriage consisting of a plate comprising a connecting bar 27 of the claws, longitudinal members 28 fixed by one end to the aforementioned connecting bar, and by the other end, to a cross member 29, having a central section parallel to the plane of the plate, and end portions each having a square arm with two branches 29A, 29B, said arms themselves being substantially bent at right angles, downwards, by compared to the central section.
  • the aforementioned crosspiece is fixed by hinge pin 32, 33, and at the elbows of the square arms 29A, 29B, to slides 35, 36 movable on two rails 37, 38 whose ends are fixed to the aforementioned chassis, while that the free ends of the arms 29B are themselves linked by articulations 40, 41, to an endless drive chain 42, 43 meshing with toothed wheels 44, 45, 46, 47.
  • the toothed wheels 44, 45 are fixed on a single shaft carried by the chassis C and are driven using a motor 48, while the toothed wheels 46, 47 are mounted to rotate, each on an axis 49, 50 , carried by the chassis C, this in order to allow the passage of the claws 26 during the operation of the transfer device.
  • the front stop provides as many passages 60 as there are claws; (four in the example shown); it is the same for the plate 20, which has longitudinal slots 20A extending from the front stop, to the vicinity of the discharge zone ZE.
  • the plate 20 carries a means, for example a photoelectric cell 55, suitable for actuating the aforementioned motor 48 as will be seen later, while the chassis C carries substantially directly above the evacuation zone ZE an end-of-travel control 70 for moving the claw-carrying carriage, and substantially in line with the stack-forming zone, another control member 71 so that the carriage claw holder is movable between these two controls 70, 71.
  • a means for example a photoelectric cell 55, suitable for actuating the aforementioned motor 48 as will be seen later
  • the chassis C carries substantially directly above the evacuation zone ZE an end-of-travel control 70 for moving the claw-carrying carriage, and substantially in line with the stack-forming zone, another control member 71 so that the carriage claw holder is movable between these two controls 70, 71.
  • the vibrating table according to the invention is arranged as it is clearly visible in FIG. 1 in particular, at the end of the deck 11 of an assembly machine so that the leaves released from the assembly deck 11 fall to the area ZF stack formation; the plate as well as the front and longitudinal stops which are integral with it are inclined along a diagonal D of the plate 20 so that the bottom point of the plate is located at the corner formed by said stops and the plate, this low point being indicated by PB at Figure 1.
  • the vibrating table thus oriented, the leaves dropped in line with the ZF pile formation zone, are, under the effect of vibrations, directed towards the stops both longitudinal and front on which, by two sides, they take support.
  • a stack of sheets, of different size and / or nature is being formed at the stack forming area ZF, while the discharge area ZE is stack free , and that the transfer device is stopped in the standby position.
  • the motor 48 When the detection member sensitive to a characteristic size (not shown in the drawings because it can be of any kind) for example sensitive to a predetermined number of sheets, to the height or to the weight, of a stack, or still at a time measurement, is actuated, the motor 48 is set in motion, which drives the carriage in translation and, consequently, the claws 26 - which then form a movable front stop - towards the evacuation zone; the ZF stack formation area is therefore freed and a new stack can be formed at this location.
  • a characteristic size for example sensitive to a predetermined number of sheets, to the height or to the weight, of a stack, or still at a time measurement
  • the carriage is stopped in its movement when one of the sliders, for example the slider 36, abutting the control 70, for example a stop microswitch, actuates the latter; the stack thus displaced is then at the evacuation zone ZE; it masks the photoelectric cell 55 which keeps the carriage immobilized in the aforementioned zone until the battery has been discharged.
  • the control 70 for example a stop microswitch
  • the first is that an operator evacuates the battery present in zone ZE; in doing so, the photocell 55 being released, orders the starting of the drive motor 48 of the chains, so that the carriage and the claws are moved towards the zone of formation of pile ZF (FIG. 5) until that the slide 36 actuates the control member 71 which stops the carriage. At this location of the carriage, the claws 26 are returned to the standby position between the lights 60 formed in the fixed front stop 21.
  • the formed stack brought to the discharge zone ZE is not discharged in time for any reason.
  • the photoelectric cell 55 does not give the order to start to the carriage which thus remains immobilized in the battery discharge zone, and when the battery in the battery formation zone reaches the predetermined characteristic quantity, l control member 71 not being biased by the slider 36 orders the immediate stopping of the feed device of the collating, punching or other machine, so that the feeding of the sheet articles to the stack forming zone ZF is stopped.
  • a formed stack is therefore in place at the stack forming area, and another formed stack is in place at the discharge area; when the latter is evacuated, the photoelectric cell 55 orders the departure of the carriage towards the stack formation zone, the claws 26 being retracted during this movement under the underside of the plate 20.
  • the collator is no longer stopped at the end of each stack, but only if a stack brought to the discharge zone is not removed at the end of forming a pile at the formation area.
