Definitions

  • the invention relates to a panel loading device for panel sizing saws in an embodiment according to the preamble of claim 1.
  • the roller accelerator forms a stationary structural unit connected upstream of a machine table of a plate dividing saw. This is fed by a slide-in car individual, from a stack of plates pushed plates, which, as soon as they get between the lower, drivable acceleration rollers and the upper, lowerable pressure rollers of the roller accelerator, are grasped by the rollers and conveyed to the machine table of the panel sizing saw at a significantly higher transport speed. It is thus possible to have the slide-in cart run relatively short transport distances and to again provide a plate of the plate stack on the roller accelerator as soon as the plate previously delivered has left it.
  • roller accelerators and slide-in carriages thus form two independent units that can be controlled and controlled.
  • the roller accelerator does not allow the transfer trolley to be used in conjunction with the slide-in trolley to lift high-weight plates from the stack of plates, for example by means of suction lifting elements, and to place them on the machine table bypassing the roller accelerator (not documentable, company-internal state of the art by the applicant).
  • the invention has for its object to provide a plate loading device of the type explained in the preamble of claim 1, the roller accelerator also using the transfer carriage in cooperation with the Slide-in trolleys for transporting correspondingly heavy plates from the plate stack to the machine table.
  • the transfer carriage thus also forms a component of the roller accelerator, in that it carries at least one upper pressure roller and can be positioned in such a way that both further transport of plates by at least one acceleration roller and one pressure roller is possible, as well as, if necessary, alignment of individual plates placed on the machine table or a plate pack is possible by placing it at an angle stop.
  • a further development of the invention according to claim 2 makes it possible to be able to use movable carriers and transfer carriages by bypassing a plate transport by roller acceleration for the transport of heavy plates or plates provided with a sensitive surface from the plate stack directly onto the machine table.
  • the movable carrier alone allows thicker individual plates or plate packs made of thinner individual plates to be pushed from the plate stack over the acceleration rollers onto the machine table, in which case the transfer carriage can remain in a corresponding position above the machine table in the rest position.
  • the upper part of the conventional roller accelerator is thus formed by the transfer carriage, which can be equipped with lowerable carriers and / or suction elements for the transport of individual plates or plate packs.
  • all of the carriages can advantageously be coupled with at least one endless, driven towing element guided over deflection rollers for the purpose of driving them. Further advantageous embodiments of the invention are the subject of subclaims.
  • the loading device has a receptacle 10 for a stack of plates 12 to be stacked, for example formed from raw plates. This can be formed, for example, by a lifting table. Individual plates 14 or plate packs are to be transported from the raw plate stack 12 to a machine table 16 of a plate dividing saw, not shown.
  • a horizontally movable, not shown slide-in cart is used in a known manner, which is equipped with correspondingly lifting and lowering plate driving elements or, as shown, a movable carrier 18 to be fixed for the plate transport above the raw plate stack 12, with several, the plate feed Takeover driving units 20 is equipped, which work independently of the carrier 18 in such a way that when the carrier 18 is shut down, the plate is pushed off.
  • a roller accelerator 22 Downstream of the carrier 18 is a roller accelerator 22, which detects the plates 14 pushed by the plate driving units 20 from the raw plate stack 12 and feeds them to the machine table 16 at an increased transport speed.
  • the roller accelerator 22 preferably has a multiplicity of axially spaced, drivable, lower acceleration rollers 24, and the same number of them, which are assigned to them and which are used for the plate transport with their axis essentially in the vertical plane aa receiving the drive shaft 26 of the acceleration rollers 24. lowerable pressure rollers 28.
  • a transfer carriage 30 is provided between the slide-in carriage or the movable support 18 and the panel sizing saw, which is no longer shown, which, analogous to the support 18, can be moved and ascertained on a guide frame 32 associated therewith above the raw panel stack 12 and the machine table 16.
  • both carriages 18, 30 can be moved individually or together, in particular program-controlled, via a common drive device 34.
  • the transfer carriage 30 also forms part of the roller accelerator 22, in that the upper pressure rollers 28 of the transfer carriage 30 are guided in a suitable manner in each case by means of a cylinder unit 36 so that they can be raised and lowered.
  • the transfer carriage 30 also carries plate carrier elements 38 which can be raised and lowered and which can each be formed, for example, by the piston rod of a cylinder unit 40. These are laterally offset from the upper pressure rollers 28 in such a way that they can be controlled in the vertical plane a-a between the acceleration rollers 24 downwards into their plate driving position.
  • the cylinder units 40 as seen in the plate transport direction, are preferably arranged behind the upper pressure rollers 28.
  • Cylinder units 40 and upper pressure rollers 28 are held on a common crossbar 42 of the transfer carriage 30.
  • the acceleration rollers 24 or the machine table 16 are preferably vertically continuously adjustable, which is not shown for the sake of simplicity.
  • the drive device 34 is preferably formed by two endless trailing elements, which consist of deflection rollers 44 and 46 and extend preferably in the plate transport direction and preferably consist of toothed belts 48, which are provided opposite one another at the same height.
  • the towing elements could also be formed, for example, by chains or ropes.
  • the carrier 18 or, alternatively to this, a slide-in trolley (not shown), the transfer trolley 30 and, if appropriate, at least one further trolley of the loading device guided on the guide frame 32 between the two towing members 48 are in a suitable manner with the same run 50 of the toothed belt 48 in particular program-controlled, for example by clamping a section of its run 50 between a clamping surface 60 and a clamping jaw 64 of the carriages 18, 30 which can be carried along can be coupled by a linearly movable actuating wedge 62.
  • the actuating wedge 62 and the clamping jaw 64 are guided in a common guide housing 66 of a coupling device 68, which at the same time has the clamping surface 60.
  • the transfer carriage 30 becomes so by automatically coupling to the belt spaces 50 shifted far in the direction of the carrier 18 fixed in a push-off position until the plate driving elements 38 are located behind the plate pack 52. Thereafter, the timing belt 48 are controlled in the opposite direction, with the plate pack 52 z. B. by the transfer carriage 30 in the direction of a z. B. is moved upward pivotable plate stop 54.
  • the plate pack 52 can subsequently be shifted in the feed direction step by step for example by the transfer carriage 30 in cooperation with the strands 50 of the toothed belt 48 for trimming and dividing.
  • the plate stop 54 for plate alignment and for this purpose to move it towards a stop surface provided behind the roller accelerator 22.
  • the transfer carriage 30 can, as shown in the plate carrier unit 20 of the movable carrier 18 shown, additionally or exclusively with connectable to a vacuum source, for. B. be equipped by means of a cylinder unit 56 raised and lowered suction heads 58. This makes it possible to transfer the transfer carriage 30 also to be controlled when the upper pressure rollers 28 are raised via the plate stack 12 and, in cooperation with the suction heads 58 of the carrier 18, to lift heavy individual plates 14 in particular. Then both movable units 18, 30 are to be coupled to the runs 50 of the two toothed belts 48 and to be moved over the machine table 16 to the plate storage.
  • roller accelerator 22 Due to the division of the roller accelerator 22 according to the invention, it no longer forms a transport obstacle for plates to be pushed onto the machine table 16, in that its lower acceleration rollers 24 can be run over by the plate 14.
  • carriages to be driven by the toothed belts 48 can be controlled jointly in the same direction or individually, if necessary by different distances, in opposite directions.
  • a third movable unit can, for example, form a conventional transfer carriage which is only equipped with lifting and lowering drivers and which takes over the plate feed to the panel sizing saw.
  • the construction of the guide frame 32 can also have only a horizontal guide rail, on the underside of which the plate driving units 20 could be provided on a movably arranged cross member or at least one slide-in carriage. In this case, a towing device would be sufficient to drive all the units to be towed.
