Definitions

  • the invention relates to a loading device for panel sizing saws, with a lifting table for receiving a stack of panels, for example formed from raw panels, and a carrier which can be moved horizontally above the lifting table and which, transversely to the loading apparatus, has a plurality of panel driving units with driving elements for driving panels away from the panel stack Has lifting table in the direction of a roller accelerator upstream of the panel sizing saw.
  • Charging devices of this type are the internal state of the art, which cannot be documented in printed form Applicant already known.
  • the movable support provided with a plurality of driving elements for pushing plates off the plate stack forms a slide-in carriage which carries out the plate slide-in movement itself.
  • the trolley construction must be designed to be correspondingly stable. Accordingly, it has a high weight.
  • the entire heavy-duty slide-in cart must therefore be steered towards the roller accelerator and back into its starting position. The masses to be accelerated and decelerated essentially determine the working cycle of such loading devices.
  • the invention is therefore based on the object of significantly increasing the working cycle of such loading devices for stacking plates.
  • the plate entrainment elements are thus moved back and forth relative to the movable carrier carrying them by means of a drive device, the carrier as such being capable of being fixed in the position in which it was initially set relative to the stack of plates to be stacked when the loading device was set up.
  • the carrier carrying the driving elements thus likewise still forms a movable carriage in order to be able to move it into the necessary set-up position for processing stacked plates, but a plate insertion function is not required for this.
  • a safe operation of the plate driving elements can also be ensured if the plate material to be pushed off the plate stack is only a few millimeters thin, flexible plates, for example made of hard fibers or corresponding materials.
  • the suction heads assigned to the plate driving elements also allow plates of high weight to be tipped over before being taken along or, in cooperation with a further transport carriage, only be lifted off the plate stack and transported on by suction.
  • a preferred embodiment of the entrainment elements is the subject of claim 3.
  • these are formed by drag hooks each articulated on a guide carriage of the carrier, which are raised by a pivoting device when the guide carriages are returned to their starting position in such a way that they do not coincide when the plate stack is passed over come into contact with the top side of the top stacking plate and can damage it.
  • the individual guide carriages of the entrainment elements or drag hooks can be moved by a common drive device. This can be accomplished technically advantageously according to claim 5. Since the Carrying elements or drag hooks as well as their guide carriages for the plate transport only have to perform opposite linear movements, an advantageous solution of their drive according to claims 6 and 7 offers itself.
  • a swivel device which deflects the drag hooks during their return transport into an upper lifting position and which works without a special drive is the subject of claim 8.
  • the movement of the tow hook, guide carriage and swivel devices is hereby initiated exclusively by the drive device or the cylinder unit, claim 9 regarding the Drive of the actuating slide of the swivel devices shows an advantageous solution.
  • the design proposal according to claim 10 allows the number of cycles of the loading device to be doubled in a technically simple manner. This is achieved in that two drag hooks are provided for each plate driving unit of the carrier and these are assigned to one another in such a way that one of the drag hooks is in its initial push-off position and the other is in its push-off end position at the beginning of a push-off of the disk. With each forward and backward movement of one of the towing elements of the towing element, one of the two towing elements is thus controlled into its initial push-off position, so that a plate is again pushed off the plate stack each time the movement of the towing element dreams is reversed.
  • a particularly advantageous arrangement of the cylinder assembly driving the towing elements or toothed belt is the subject of claim 11.
  • the loading device is designated as a whole by 10. It is connected upstream of a roller accelerator 12 of a machine table 14 of a panel sizing saw and serves to separate the machine table 14 from individual panels 16 of e.g. plate stacks 20 formed from raw plates and deposited on a lifting table 18 for dividing up on the plate saw or for forming a plate package to be divided, which has a desired number of plates, in cooperation with the roller accelerator 12 to the machine table 14.
  • a roller accelerator 12 of a machine table 14 of a panel sizing saw serves to separate the machine table 14 from individual panels 16 of e.g. plate stacks 20 formed from raw plates and deposited on a lifting table 18 for dividing up on the plate saw or for forming a plate package to be divided, which has a desired number of plates, in cooperation with the roller accelerator 12 to the machine table 14.
  • the loading device 10 has a carrier 26 which can be moved horizontally on a guide frame 24 and, for this purpose, is guided between two guide rails 28 and 30 of the guide frame 24 for this purpose. It has a crossbar 32, on which, as can be seen from FIG. 2, a plurality of plate entrainment units 34 are provided, which, viewed transversely to the plate transport direction, are provided at a lateral distance from one another.
  • a guide carriage 40 is slidably guided laterally on the guide rail 36, to which a plate driving element in the form of a drag hook 42 is articulated, the lower pivot end position of which is fixed by a carriage stop 44.
  • the lower end of a swivel lever 46 is articulated on the drag hook 42, the upper end of which is articulated on an actuation slide 48 which is likewise guided on the guide rail 36 and which, as can be seen from FIG. 4, is in turn connected to the guide rail 36 on the side of the guide carriage 40, lagging this in the plate transport direction (see FIG. 3).
  • a slide arrangement which is not shown in FIG. 3 and has the same components, is provided on the opposite longitudinal side of the guide rail 36, as can be seen in FIG. 4.
  • the corresponding slides as well as the swivel lever and the drag hook are identified by the same reference numbers, but with an index.
  • the two slide assemblies are driven by a towing element which is assigned to them, preferably in the form of a toothed belt 54 which is guided around deflection rollers 50, 52. Alternatively, this could also be formed, for example, by a chain or rope.
  • the deflection rollers 50, 52 are each in one mounted on a front end of the guide rail bracket 56 and 58 respectively.
  • the deflection roller 52 is in this case arranged in a rotationally fixed manner on a transmission shaft 60 rotatably mounted in the bearing block 58.
  • Both belt spaces 62 and 64 each serve to drive one of the two slide arrangements formed by the slides 40 or 40 ', 48 or 48', the actuating slide 48 using a clamping device 66 on the upper belt drum 64 and the actuating slide 48 'using one of these corresponding clamping device 70 is clamped to the lower belt drum 62.
  • the two carriage arrangements 40, 48 or 40 ', 48', each guiding one of the towing hooks 42 and 42 ', are assigned to one another in such a way that one of the towing hooks 42 and 42' in its initial push-off position and the other towing hook at the start of a plate push-off is in its final deportation position.
  • All the plate driving units 34 are structurally the same in the scope described above.
  • a drive device which is preferably formed by a cylinder unit 72, which is integrated in the guide rail 36 of this plate driving unit 34.
  • the guide rail 36 preferably also forms the piston cylinder and the piston rod guide, the piston rod 74 being connected to the clamping device 70 seated on the belt drum 62 via a radial driver 78 which extends through a longitudinal slot 76 of the guide rail 36.
  • the toothed belt 54 and the deflection roller 52 and the transmission shaft 60 take place here at the same time also the toothed belt drive of all further plate driving units 34, so that a synchronous drive of all slide arrangements or drag hooks 42, 42 'is ensured for the plate driving.
  • the individual plate driving units 34 are also assigned suction units 80 which are fastened to the receiving profile 38 of the carrier 26. These are each provided with a suction head 82 which can be connected to a vacuum source, which is attached to the free end of a piston rod 84 of a cylinder unit 86 and is vertically movable or can be lowered onto the upper plate of the plate stack 20.
  • the support 26 is to be adjusted with respect to the plate stack 20 in such a way that the suction heads 82 are in the lowered state in the region of the rear plate longitudinal edge of the upper stack plate.
  • the plate 16 to be pushed off is sucked in and released in the area of its rear edge, after which the cylinder unit 72 then comes into operation, for example the drag hook 42 engages behind the plate rear edge and pushes the plate 16 in the direction of the roller accelerator 12 , which captures them and places them on the machine table 14.
  • the towing hook 42 has reached its front push-off end position, the towing hook 42 ′ is already in its rear push-off starting position in order to already feed a further plate 16 to the roller accelerator 12 during the return transport of the towing hook 42.
