Definitions

  • the invention relates to a device for removing a workpiece from a cutting table, which comprises at least one blank cut out of a flexible web of fiber material, with a relative to the web receiving the blank receiving blank cutting table movable lifting device which increases a rising from the cutting table contact surface for the workpiece for progressive lifting of the workpiece from the cutting table, with a receiving the workpiece after the start-up surface progressively receiving device and with a lifting device for the lifting device facing the workpiece edge.
  • blanks cut out of a flexible material web can not be lifted out of the material web by means of lifting devices that can be subjected to negative pressure because these blanks are permeable to air, as is generally the case with webs of a fibrous material, then these blanks can be detected mechanically.
  • Sliding movements between the conveyor belt and the workpiece can be avoided by an appropriate choice of the speed of the conveyor belt adapted to the advancing movement of the lifting device relative to the cutting table.
  • loads on the workpiece can be excluded from a fiber material by frictional forces that occur when lifting the workpiece along the contact surface of the lifting device, the finger forming this contact surface can be equipped with rotating conveyor belts.
  • the underrunning of the workpiece with the lifting device can additionally be assisted by a lifting device associated with the cutting table, which raises the workpiece at least in the region of the workpiece edge facing the lifting device, namely with correspondingly distributed lifting units.
  • These lifting units may comprise the cutting table passing through lifting pins, the lanes for receiving the stop surface forming fingers of the lifting device form, but also consist of compressed air nozzles that produce a the edge portion of the workpiece from the cutting table contrasting air cushion to facilitate the subsequent engagement of the workpiece by the lifting device.
  • the disadvantage is that no separation of the blanks of the remaining web is possible.
  • a lock for the workpiece receiving strand of the conveyor belt is provided so that after moving the pallet from the straightening table on the cutting table in resetting the pallet the conveyor belt with the workpiece can be held stationary against the cutting table with the effect in that the workpiece is deposited progressively on the cutting table in accordance with the return movement of the pallet, without relative movement between the conveyor belt and the workpiece.
  • this known device can place workpieces in a predetermined position in the correct position on a cutting table, but not remove workpieces from a cutting table with a separation of the blanks of the remaining web.
  • the invention is therefore based on the object, a device for removing a workpiece from a cutting table of the type described in such a way that cut from a web cut blanks can be removed separately from the remaining web from the cutting table without fear of overloading the blanks.
  • the invention solves the problem set by the fact that provided at a distance above the cutting table lifting device to the length the receiving section facing the edge portion of the blank customizable recording and holds the recorded edge portion in a lifted off the cutting table transfer position and that the lifting device between the lifting device and the resting on the cutting table web is movable.
  • a lifting device which is arranged at a distance above the cutting table and has an adaptable to the length of the lifting portion facing edge portion of the blank receptacle for this edge portion, the space between the lifted from the cutting table blank and the remaining, remaining on the cutting table Web for an unimpeded ride underneath the raised blank by the lifting freely, which is performed above the remaining on the cutting table, remaining web so that excluding only initially raised edge of the rest of the web blank recorded by the lifting and progressively under a transfer to the subsequent Receiving device is lifted out of the remaining, remaining on the cutting table web.
  • the receiving device for the blank following the lifting device can be designed differently.
  • the receiving device forms a support fixed to the cutting table during the blank takeover with a table-parallel receiving surface for cutting on the underside facing the cutting table, and that the lifting device deflects a end of the lifting device facing the blank to be lifted, along the until to the receiving surface on the underside of the carrier rising ramp surface guided band, which is held stationary with its running from the run-area strand relative to the carrier and clamps the blank between itself and the receiving surface of the support. Due to this measure, the blank cut off from the cutting table by the lifting device is pressed against the receiving surface on the underside of the carrier of the receiving device by means of the abutment surface, namely by means of a belt.
  • Trum is held stationary relative to the cutting table, so that no sliding movement is established between the tape and the blank lifted only from the cutting blank.
  • the blank can therefore be kept pressed by means of this band from below to the receiving surface of the receiving device, the support surface forming carrier yes also during the blank takeover is immovably connected to the cutting table.
  • the band For clamping holding the blank between the tape receiving the blank and the receiving surface on the underside of the carrier, the band can be made permeable to air, so sucked at a negative pressure on the underside of the carrier tape with the blank to the receiving surface of the wearer and held against displacement on the receiving surface ,
  • the band which can be applied to the underside of the carrier with the aid of the lifting device may be made of a ferromagnetic material, the carrier being magnetically formed on its underside in order to attract this band to the receiving surface on the underside of the carrier via a corresponding magnetic field.
  • the receiving surface could be provided with a magnetic support.
  • the blank held on the underside of this carrier can then be conveyed out of the region of the cutting table with the support of the receiving device in order to be deposited on a table for further processing via the tape securing the system to the carrier.
  • the clamping of the blank on a receiving surface on the underside of the carrier is indeed comparatively complex, but associated with a small footprint, because the receiving device is held stationary during the blank takeover on the cutting table.
  • the receiving device can form a support for cutting, which is provided following the contact surface of the lifting device and which is connected to the lifting device so as to be non-displaceable.
  • the relative movement of the blank relative to the receiving device can be compensated by a guided to the lifting blank facing the end of the lifting device deflected, guided along the rising contact surface band, which is held stationary with its running from the run-up run against the cutting table.
  • the support for the blank slidably connected to the lifting device has a carrier with a table-parallel support surface for the blank, the space required for such a device increases at least by the length of this support surface in the direction of displacement of the lifting device.
  • the blank cut off from the receiving table via the contact surface of the lifting device comes to rest on the supporting surface of the carrier, which eliminates the need for additional support measures for the blank.
  • the projection of the receiving device displaceably connected to the lifting device in the direction of displacement can then be shortened if the support for the blank is composed of individual support members guided along a guide, the guide having a table-parallel section and an adjoining section recirculated to the table-parallel section, so that the projection is shortened around the return guide section.
  • the belt In order to ensure a slidable support of the male blank via the belt which can be displaced relative to the contact surface of the lifting device, the belt must be able to be moved at least in a length corresponding to the length of the blank in the direction of displacement of the lifting device.
  • This tape path can be ensured by the fact that the tape receiving the blank is endlessly guided around deflections. But it is also possible to unwind the blank receiving tape from one of the lifting device associated supply roll and to keep stationary with its running from the run-up end of the cutting table, with no difference in terms of the movement of the blank receiving Bandtrumes.
  • a further embodiment of the receiving device is to this recording device with a winding roll for cutting to provided, which is held displaceable in a lifting device belonging to the frame height and rolls with its winding at the cutting table. Because of the rolling movement of the recorded by the winding roller on the cutting table, the length of the wound blank corresponds to the displacement length of the lifting device, which is an essential condition for a train and slip-free recording of the blank on the winding roll.
  • the vertical displacement of the winding roll is required for the adaptation to the winding diameter.
  • the leadership of the winding roll to their height adjustment can extend transversely to the tapered portion of the blank.

  • the cover of the cutting table with the remaining material web remaining on the cutting table ensures advantageous rolling conditions for the blank wrapping without having to fear disadvantageous influence on the blank by rolling on the remaining material web.
  • the lifting device for detecting the edge portion of the blank can be designed differently, because it is important above all to raise the edge portion for driving under with the lifting device.
  • the lifting of the edge portion by the lifting device entails the risk of a tensile load of the raised edge portion, if it is not taken care of a length compensation of the raised edge portion, which causes a movement component of the gripped edge portion parallel to the cutting table.
  • the recording of the lifting device may have a rising from the edge portion to be detected for blanking stroke, which compared to a control of the recording of the lifting device in two axes allows a simpler design.
  • the edge portion of the blank to be lifted could also be pivoted about a corresponding axis, for example by means of a gripper roller.
  • the lifting device may include each controllable for lifting units, the blank from the side of the kerf under cross gripping elements and cooperating with the gripping elements, the edge portion of the blank between them and clamping elements which clamp the gripping elements so that the edge section of the blank to be lifted is lifted by the gripping elements and held by the clamping bodies in contact with the gripping elements without having to pierce the fiber structure.
