Definitions

  • the invention relates to a device for locking the suction nozzle of suction pads on the suction head of a sheet feeder according to the preamble of claim 1.
  • Such a device is known from DE-PS 23 09 013. It is used when so-called jumping vacuums are used as separating suction devices and special drive means for the lifting movement of the separating suction device are dispensed with.
  • a lever pivotally mounted about a horizontal axis is provided on the suction head, said lever having a cam roller interacting with a control cam and at its free end a cross bar holding the separating nozzles.
  • the support is formed by rollers which are supported at the ends of the crossbar and which interact with flanges which extend horizontally at the suction nozzles of the separating suction devices.
  • the means for locking the suction nozzle of the separating suction device thus have a separate drive with its own control curve, through which the suction nozzle of the separating suction device is forcibly guided downward when the rear edge of the sheet conveyed into the feeder has left the area of the suction nozzle of the separating suction device.
  • a device for locking the suction nozzle of a vibrating movement separating suction device on the suction head of a sheet feeder in which a pawl in the form of a double lever is pivotally mounted on the separating suction device, one arm of which is an abutment for a nose on the suction nozzle has and the other arm cooperates with a stop that on a stack button is arranged.
  • the separating suction device is designed as a jumping suction device, so that the suction nozzle jumps up in its rear swivel position in the stack of sheets after the uppermost sheet has been sucked in, whereupon the abutment of the pawl engages behind the nose on the suction nozzle and holds it in the upper position until the in the Feeder-fed sheets have left the area of the now ventilated suction nozzle with its rear edge.
  • the stop arranged on the pushbutton releases the lock, so that the suction nozzle falls down.
  • the object of the invention is to provide a locking device for a separating suction device designed as a jumping suction device in the upper end position with a forced release of the suction nozzle in a suction head in the suction stroke of the machine with a touch foot resting on the rear edge of the sheet stack.
  • the counter bearing for the support on the suction nozzle is formed on a link body which is mounted on the axis of a toggle joint between drive members for the movement of the feeler foot and at a fixed point of the suction head is rotatable and tangential to the axis of the toggle joint linear is slidably guided.
  • Embodiments of the invention are shown schematically in the drawing.
  • the exemplary embodiments show a suction head in which a feeler foot 1 can be placed on the trailing edge of the uppermost sheet 2 in the sheet stack 3 in the work cycle of the machine and can be pivoted back into a raised end position.
  • the feeler foot 1 is articulated on the one hand with the free end of one arm 4a of a double lever 4 and on the other hand on a guide lever 5, both of which are pivotably mounted about axes 6 and 7 extending transversely to the conveying direction on the housing 8 of the suction head, these levers being so one on top of the other are coordinated that the feeler foot 1 swings back and forth again from the position shown with full lines to the position shown with dash-dotted lines.
  • the other arm 4b of the double lever 4 is articulated to one end of a coupling 9, the other end of which is articulated to a roller lever 10, one end of which is articulated on the housing 8 and which carries a cam roller 11, which by means of a at the other end of the roller lever 10 engaging spring 12 is pressed against the circumference of a driven cam 13.
  • This cam 13 thus controls the movement of the feeler 1 in the working cycle of the suction head.
  • a link body 15 can be pivoted, which with a fork-shaped link 16 onto the blow pipe 17, which is fixedly arranged on the housing 8, for the supply of blowing air to loosening fans or the like is pushed on, so that this link body 15, 16 is moved synchronously with the feeler 1 from the position shown in full lines in FIG. 1 to the position shown in broken lines and back.
  • the separating suction device 18 is designed as a jumping suction device and is attached to the housing 8.
  • the lower part of this jumping suction device with the suction nozzle 19 falls at atmospheric internal pressure due to its own weight and possibly with the support of an inner spring 20 (FIG. 2) into the lower end position, so that the suction nozzle rests on the uppermost sheet 2 in the sheet stack 3.
  • an inner spring 20 FIG. 2
  • the suction nozzle 19 jumps into the upper end position and lifts the rear end of the uppermost sheet 2 from the sheet stack 3.
  • the feeler is swiveled back to the rear position indicated by a dash-dotted line. Now, vacuum cleaners not shown in the drawing take over the lifted sheet 2 and transport it towards the feeder.
  • the tactile foot 1 returns the position shown in full line back, the link body 15 is pivoted into the position shown in full line.
  • a counter bearing 20 fastened to the link body 15 engages under a support 21 which is arranged on the side of the suction nozzle 19. Characterized the suction nozzle 19 is locked in the upper position so that it does not fall back into the lower position when the vacuum in the suction nozzle is released.
  • the feeler foot 1 is pivoted into the position drawn with a full line.
  • the feeler foot 1 swings back into the position shown with a dash-dotted line, and at the same time the link body 15 with the counter-bearing 20 attached to it releases the support 21 on the suction nozzle 19, so that it also falls back into the lower end position shown with a dash-dotted line and for lifting of the next sheet from sheet stack 3 can be subjected to negative pressure again.
  • FIG. 2 illustrates the arrangement of a pair of separating suction cups, which can be arranged symmetrically to the central longitudinal plane of the machine at a distance from one another.
  • This figure also shows conventional guide springs 22 which secure the suction nozzles of the separating suction devices against rotation and mark the lower end position for the suction nozzle.
  • the arrangement of the tactile foot 1 and the means of the drive for the tactile foot 1 correspond to the description of the exemplary embodiment in FIGS. 1 and 2.
  • a position is provided as a counter bearing for the support 21, a leaf spring 23 which is fastened to a sheet metal 24 which is located on the housing 8 of the suction head next to the separating suction device 18 extends downward.
  • a nose-shaped profile of the leaf spring 23 in the side view passes through a recess in the plate 24 and forms the counter bearing for the support on the suction nozzle 19 of the separating suction device 18.
  • the engagement position of the counter bearing and the support shown in full line on the drawing corresponds to the relaxed state of the leaf spring 23.
  • a release lever 25 is provided which engages with one end in the design profile of the leaf spring 23 and is attached at the other end to a pivot shaft 26 which is connected to the roller lever 10 via a pivot lever 27 and a coupling plate 28 .
  • the leaf spring is relieved, so that it returns to a waiting position for the locking to take effect.
  • the profiling of the leaf spring 23 has an oblique sliding surface, so that the support 21 can move past the leaf spring 23 past the latter into the upper end position of the suction nozzle 19 with elastic deformation.
  • the swivel shaft 26 is mounted in a tube 29 which is firmly connected to the housing 8 of the suction head at one or more points and has slot-shaped recesses on the circumference which differ from that with the swivel shaft 26 connected pivot lever 27 is penetrated.
