Definitions

  • the present invention relates to a press receiving station for forming sheets of paper or cardboard with a transverse roll placed downstream of the receiving zone and a carriage movable downstream of said roll, which can receive a plurality of bars to form a grid non-stop receiving poses, said carriage being guided by a carrier device in the longitudinal direction.
  • the separation of the poses consists, after shaping and complete ejection of the waste, to break the points of attachment between the poses of a sheet by means of a male upper tool and of a lower female tool vertically mounted one above the other in the sheet receiving area.
  • the upper tool consists of pushing elements slightly smaller than the perimeter of the poses.
  • the lower tool consists of longitudinal and transverse bars forming a grid corresponding to the perimeter of the poses. The poses fall through the meshes of this grid and stack vertically in the reception area.
  • a periodical inserting of a stabilizing sheet is necessary on the receiving pallet of the receiving station.
  • This device comprises a carriage movable in the longitudinal direction of the press.
  • the carriage comprises two transverse beams on which can be arranged in the longitudinal direction bars intended to form a non-stop receiving grid of poses.
  • the bars generally have a shape similar to a cane.
  • the head of the cane can engage in a notch in the trolley beam furthest from the receiving station and can be fixed by screwing.
  • the stem of the cane rests, in an area quite close to the head of the rod, on the second transverse beam of the carriage, and, in an area near the other end of the rod, on a transverse roller located in the immediate vicinity and downstream of the landing receiving area.
  • the movable carriage moves to bring the bars under the lower parting separation tool and a pair of bars comes to support every pose that falls.
  • the non-stop receiving grid momentarily receives the poses that pile up during inserting operations. After each inserting operation, the bars forming the grid are withdrawn from the reception zone, by longitudinal displacement of the mobile carriage, crossing with the vertical rows of the lower tool for separating poses, to deposit the poses on the sheet. inserting.
  • a preselector defines the number of cuts per packet and the number of packets and / or the height of the piles.
  • the entire device operates automatically and continuously according to a preprogrammed cycle.
  • a disadvantage of this non-stop receiving grid device lies in the fact that the temporary storage height on the bars engaged in the reception zone is only of the order of 35 mm.
  • an inserting cycle takes about 20 to 30 seconds.
  • the storage height is sufficient for thin or light weight paperboard sheets and for relatively slow processing speeds. For the fastest current production rates, as well as for relatively thick cardboard sheets or cardboard, this storage height becomes insufficient. If the thickness of a new sheet of cardboard is of the order of 3 tenths of a millimeter, this thickness increases to 5 tenths or more, when it is pushed back to achieve the folds of the cardboard. With a production rate of 3 sheets per second, the available storage height of 35 mm can be reached in about 20 seconds or less.
  • the document DE 195 16 023 discloses a sheet stacker comprising a movable carriage consisting of a longitudinally guided laying receiving grid, said stacker comprising lifting means capable of producing a vertical displacement of said movable carriage, downwards.
  • an insert sheet is deposited on the blank receiving grid prior to being fed under the lower blanking tool.
  • the poses are then stacked on the insert sheet as the moving carriage moves vertically downward.
  • the object of the present invention is to increase the poses storage capacity on the non-stop receiving grid of a receiving station of the defined input type, while keeping the drop height of the poses at a minimum to ensure a good formation of batteries.
  • the receiving grid placed on the movable carriage and the roller, moves vertically downward while the poses accumulate on the grid during the inserting operation.
  • the time available for the inserting cycle is considerably longer.
  • the drop height of the poses thus becomes adjustable, and the free fall height can be kept low, which is particularly advantageous for small poses.
  • the downward vertical movement is preprogrammed according to the work performed by the press, in particular according to the thickness of the treated board.
  • the vertical downward movement is slaved to the detection of the top sheet of the stack resting on the receiving grid.
  • the carrier device of the movable carriage and the transverse roller can be fixedly mounted in a vertically movable frame.
  • the vertically movable frame may be a chassis traversing the entire width of the station, suspended on both sides by chains driven by a single motor via a transmission shaft.
  • the elevating means comprise means for correcting and maintaining the horizontality of the upper face of the bars constituting the non-stop receiving grid.
  • These correction means may comprise lateral racks and guide rollers and / or torsion bars connecting portions remote from the vertically movable frame.
  • the vertical stroke of the non-stop receiving grid can be adjustable between a high position, where preferably the height of fall is minimal, and a low position, this low position being determined by the length of the rows of the lower parting separation tool.
  • This low position can be preprogrammed: the length of the rows of the lower parting separation tool is normally known and can therefore be entered into the programming of the machine. Instead of integrating this parameter into the program, it is also possible to detect the position of the grid relative to the ranger. To do this, the vertically movable frame may carry, upstream of the transverse roller, a feeler horizontally scanning the space immediately below the free ends of the bars constituting the receiving grid, to detect the height of the frame where the gate drops to below the lower end of the rows.
  • the figure 1 shows, in side elevation, a chassis 1 through with the means causing its vertical movement.
  • the frame is composed of two horizontal longitudinal beams 3. These two beams are arranged near the side walls, driver side (DC) and opposite side to the driver (coc) of the frame of the receiving station of the press.
  • the two horizontal longitudinal beams 3 are connected by at least one transverse horizontal beam 12 which connects the ends of the horizontal longitudinal beams 3 located near the receiving zone of the poses.
  • At the other end of the horizontal longitudinal beams 3 are fixed two vertical beams 6.
  • the two pairs of beams 3 and 6 have an L-shaped configuration on either side, c, c. and coc of the machine; the assembly constituted by the 6 beams 3, 6, 11, 12 is rigid.
  • Each of the two longitudinal horizontal beams 3 carries on its vertical side facing the axis of the machine a set of longitudinal horizontal rules 4, 5 screwed in 2 on the beams 3.
  • the rules 4, 5 constitute rails carrying and guiding a movable carriage.
  • the mobile cart itself is not represented on the figure 1 , but his drive system is represented in dashed lines.
  • This drive system comprises a chain 13, whose two ends are fixed to the movable carriage, forming a closed loop.
  • the chain 13 is stretched between a return wheel 14 located near the beam 12 and a gear 15 arranged at the upper end of the beam 6.
  • a second chain 16 is arranged on the idler gear 15 and forms a closed loop, stretched at the lower end of the vertical beam 6 around a drive pinion 17, set in motion by a motor mounted and fixed at this level on the vertical beam 6 and not shown in the figure.
  • the assembly consisting of the motor, the drive gear 17, the chain 16, the idler gear 15, the chain 13 and the idler wheel 14 allows the non-stop receiving grid to move between a position resting where the carriage is moved back close to the vertical beams 6 and an inserting position, where the movable carriage is close to the transverse beam 12.
  • the two longitudinal longitudinal beams 3 carry each other at their end close to the transverse beam 12, a roller 18 on which rests and rolls the free end of the bars constituting the non-stop grid.
  • the vertical displacement of the through frame 1 is provided by means of a motor 19 integral with the frame of the receiving station of the press.
  • the rotation of the motor 19 causes, through a chain 20 and a toothed pinion 21, the rotation of a horizontal and transverse transmission shaft 22, located in the lower part of the frame of the press.
  • the transmission shaft 22 carries at each of its ends a pinion gear 23 moving a chain 24 whose one end is free and whose other end 26, after passing on a pinion gear 27, is fixed to the lower end of a vertical beam 6.
  • the rotation of the motor 19, in one direction or the other, causes the vertical displacement of the beams 6.
  • the beams 6 are suspended on the chains 26. They are also kept suspended near the side walls of the frame of the receiving station by means of two rollers 28 and 29 mounted on these walls by L-shaped fasteners.
  • the front / rear horizontality of the beams 3, rails 4, 5 and, starting from the mobile carriage and the receiving grid is ensured, on each side of the frame 1, by means of a horizontal and longitudinal torsion bar 8, which carries at its two ends two pinions 7, 30, identical, coaxial and integral with the torsion bar.
  • the axis of the gears and the bar is carried by axis supports 33, 32 integral with the beam 3.
  • Each of the two pinions 7 and 30 meshes with a vertical rack 9, 10 respectively, integral with the wall of the frame from the press reception station.
  • An initial adjustment of the position of the racks 9, 10 makes it possible to correct a lack of horizontality of the non-stop grid.
  • the torsion bar 8, which rotates as the through frame ascends or descends, maintains the front / rear horizontality of the assembly during this vertical movement of the frame.
  • the walls of the frame of the press each carry a fixed stud 31, placed below the torsion bar 8 and against which this bar 8 would abut in the extreme low position.
  • the two studs 31 are only a safety, because in normal operation, the through frame does not reach this extreme low position.
  • the lowest position actually reached during an inserting cycle is determined by the length of the rows of the lower parting separation tool. Indeed, the top of the receiving grid must not fall below the height where the lower end of the rows is located because otherwise, when removing the bars, the batteries would not be deposited correctly on the sheet inserting.
  • the figure 2 shows a device for detecting this position.
  • the position of the lower tool for separating poses In the lower half of the figure is schematically represented the position of the lower tool for separating poses.
  • the figure 2 shows the end of the frame 1 traversing, vertically mobile, located near the receiving area poses. It shows, seen from above, the end of the longitudinal horizontal beams 3, the transverse beam 12 and, shown in dashed lines, the roller 18. Also seen at the top of the figure 2 the return wheel 14.
  • the beam 12 carries on its side located opposite the receiving area of the poses an arm 34 hinged about a vertical axis 36.
  • the rotation is controlled by a pneumatic jack 35 articulated at one of its ends to the beam 12 and at its other end to the arm 34, near the axis of rotation 36.
  • the arm 34 can describe a rotational movement in a horizontal plane.
  • the arm 34 can describe or can not describe this movement, according to whether it does not meet a row or according to, on the contrary, the movement is blocked by the meeting of the lower end of a row.
  • the movement, or the blocking of the movement is detected by a sensor in a manner known per se, for example by a contact sensor.
