Definitions

  • the invention relates to a circular stack feeder with a Feeder frame, with an upper table held on the feeder frame, with one assigned to the upper table, at least a roller and a deflection drum guided upper table conveyor belt, the roller or the deflection drum being driven in rotation is, with a lower table, with one assigned to the lower table, a roll on the stack receiving side and a stack discharge side rotary driven roller led under table conveyor, the under table around its stack delivery side Roll pivotally held on the feeder frame and against the Deflection drum is spring-biased, and with flexible guide bands, the one ends above the upper table are attached to a peripheral portion of the Extend the deflection drum between the stack receiving side Roll of the table and a deflecting element passed and underneath the under table via elastically stretchable elements are set.
  • DE 25 05 164 B1 is also a circular stack feeder known, the one feeder frame, one on the feeder frame held upper table and the upper table assigned to at least one roller and a deflection drum at a distance from each other and upper table conveyor belts running parallel to each other has, wherein the roller or the deflection drum is driven in rotation and the upper table conveyor belts are a tensioning device assigned.
  • the circular stack feeder also has a lower table and the lower table assigned at a distance arranged and running parallel to each other Under-table conveyor belts around a stack delivery roll and around a deflecting roller arrangement exciting the under-table conveyor belts to an outer and an inner deflection roller above the upper table and around the pulley outside the upper table conveyor belts back to the stack delivery side Role.
  • the object underlying the invention is the circular pile sheet feeder of the generic types mentioned at the beginning Kind in such a way that the leadership of the scaled Sheet layer around the pulley from the upper table to the lower table is improved.
  • This task is started from the circular stack feeder type mentioned solved in that the under-table conveyor from at least two separated by a space parallel running external conveyor belts there is that in alignment with the outer conveyor belts separate central conveyor belt in the same direction as that outer conveyor belts is continuously provided that the middle Conveyor belt around the roll of the under table on the stack delivery side and around a pulley arrangement to an inner pulley above the upper table and around the pulley outside the upper table conveyor belt back to the stack delivery side Role of the table is guided, and that the flexible Guide belts on each side of the middle conveyor belt are arranged, the deflecting roller arrangement on the boom frame articulated lever is assigned, at least carries a main pulley and its pivoting on Counteracts fixed elastic stretchable element counteracts.
  • the circular stack feeder designed in this way has the advantage that a secure guidance of the layer of stacked scales Arch from the upper table to the lower table is guaranteed because the layer of sheets from the sheet transfer from the top table to the pulley up to the delivery of sheets from the under table through the Pickup held by the conveyor belts by a suction wheel and transported at a constant speed.
  • the preload of the lower table against the deflection drum is achieved in that the middle conveyor belt in contact with the stack receiving role of the under table on your guided by the peripheral portion facing away from the deflection drum is. If the layer of scaly arches the outer Push the middle conveyor belt away from the deflection drum elastic stretchable element that is on the lever of the pulley assembly attacks, stretches, i.e. with the help of the lever the middle conveyor belt against the stack receiving roll of the lower table below the pulley.
  • the deflection roller arrangement expediently has a lever-side arrangement Inlet deflection roller for a deflection of the middle one Conveyor belt to the lever and the inlet side of the main pulley and one above the upper table on the feeder frame stored outer upper pulley.
  • This arrangement ensures a large outer wrap angle around the Deflection roller guided scaled sheet stack without Deflection system creates great friction.
  • the elastically stretchable element is advantageously on the lever opposite the lever-side inlet guide roller.
  • the circular stack feeder shown in FIGS. 1 and 2 has one Boom frame 1, which has two side parts and cross parts.
  • the feeder frame 1 carries an upper table 2 on the sheet receiving side has a driven roller 3 to at least an endless upper table conveyor belt 6 rotates on the driven roller 3 opposite side around a deflection drum 5 guided with a correspondingly large diameter and after a loop of about two thirds of the deflection drum 5 via a further deflection roller 4 as the lower run to the driven one Roll 3 is returned.
  • an intermediate space 18 Between the outer conveyor belts 14 and 14 'of Underneath table 11, as can be seen from FIG. 2, is an intermediate space 18, in which a middle conveyor belt 19th aligned with the outer conveyor belts 14 and 14 'in the in the same orbital direction as this.
  • the middle conveyor belt 19 is also from the stack delivery side Roller 13 as the conveyor belts 14 and 14 'driven and runs with his lower run in contact with that of the deflection drum 5 facing away from the peripheral side of the stack receiving side Roller 12 of the lower table 11, to a deflection roller arrangement 20, the middle conveyor belt 19 above the Upper table 2 leads to an upper inner deflection roller 27, the middle conveyor belt 19 in the direction of the deflection drum 5 deflects the shingled sheet stack 7 against the deflection drum 5 presses and the scaled sheet stack 7 around the guide drum 5 around the under table 1 in the area of the stack receiving side Roll 12 leads, so that continuous guidance of the scaled sheet stack 7 around the deflection drum 5 around to the under table 11 is guaranteed.
  • the deflection roller arrangement 20 consists of a lever 21 which essentially horizontally on a pivot axis 22 on the feeder frame 1 sits. At its opposite end the Lever 20 a main deflection roller 25.
  • This main deflection roller 25 is a lever-side inlet guide roller 24 in the tape running direction upstream.
  • the main deflection roller 25 steers the middle one Conveyor belt 19 essentially vertically upwards to one upper outer deflection roller 26, the middle conveyor belt 19th leads to the upper inner deflection roller 27.
  • the guide roller arrangement ensures 20 with its lever 21 and the elastically stretchable Element 23 for the middle conveyor belt 19 on the outside on the upper table conveyor belt 6 on part of the circumference of the Deflection drum 5 is present.
  • the middle conveyor belt 19 is from the upper table conveyor belt 6 removed in the peripheral region of the deflection drum 5, whereby the elastically extensible element 23 of the deflection roller arrangement stretched and the middle conveyor belt 19 against the scaled sheet stack 7 in the direction of the deflection drum 5 is pressed.
  • the stack receiving side Roll 12 of the lower table 11 in the direction of the deflection drum 5 pressed.
  • Guide bands 30 in the form of roller link chains laterally in Arrange distance from the middle conveyor belt 19 like this is shown in Fig. 2.
  • the flexible guide bands 30 are above the upper table 2 on the feeder frame 1 using a Rod 31 fixed, extend around the outside Deflection drum 5 around in the vicinity of the stack receiving side Roll 12 of the lower table 11, where it around a deflecting element 32 deflected in the form of a rod fixed to the feeder frame 1 and by means of an elastically stretchable element 33 am Feeder frame 1 with the help of a cross bar, not shown are attached.
  • Function and structure of the roller link chains are detailed in DE 37 32 419 C2 and EP 0 308 688 B1 described.
