Definitions

  • the invention relates to a work table, in particular for cutting machines for cutting flat material, with an air-permeable support forming the work surface which can be subjected to vacuum.
  • Such work tables make it possible to hold the workpieces on the work surface by applying negative pressure, which is particularly suitable for cutting flat material, since it is important here to hold on to a large area, regardless of the workpiece shape.
  • the supports are now made of perforated plates or the like, which can optionally be equipped with upstanding bristles, so that the suction effect occurs in many places, but essentially only in a punctiform manner, and the liability, in particular, for workpieces with a fibrous textile structure and less Rigidity remains unsatisfactory.
  • the feed forces that occur during processing are the material fibers or the like located here. can move and affect editing, especially cutting.
  • the invention is therefore based on the object to eliminate these deficiencies and to create a work table of the type described, which is characterized by a particularly good adhesiveness of its work surface which can be subjected to negative pressure and thereby allows flawless machining, in particular cutting, even difficult material with the lowest inherent rigidity.
  • the invention solves this problem in that the support at least partially consists of porous material.
  • the porosity of the material inevitably brings about a very even suction effect over the entire support area due to the fine distribution of the pores over the entire support surface, so that even individual threads of the workpieces to be machined can be fixed to the support by the vacuum application.
  • the porosity of the material creates a surface structure of the support with a certain roughness, which increases the adhesion between the workpiece and the work surface and forms a kind of positive connection between the pores and the threads engaging in them. leads.
  • a filter material in particular porous HD polyethylene, is ideally suited as a material, which is available as a commercially available material and does not cause any difficulties in processing to the desired edition.
  • the HD polyethylene known under the brand name Vyon has already proven its worth as a covering material.
  • the porous material can be processed in various ways for the support, whereby plates or web-like supports can be provided depending on the work table. If a plate made of the porous material inserted in a holding frame forms the support, a support pallet is created to a certain extent that is easy to handle and can also be used to transport the workpiece.
  • the support frame here provides the reinforcement, which of course can also be supplemented by a reinforcing fabric.
  • a circumferential one can also be used as a support Conveyor belt forming the porous material may be provided, which has toothed belts or perforations on the edge, so that a so-called conveyor table is formed.
  • the toothed belts also serve here, at least in part, as reinforcement and at the same time allow appropriate guidance and drive of the conveyor belt, for which purpose preferably the toothed belts of the conveyor belt interact with the toothed belts of a toothed belt drive.
  • a particularly simple and convenient way of guiding and driving results from the perforations in the corresponding teeth, knobs or the like. of the toothed belt drive can intervene.
  • a conveyor belt is also provided as a support, which consists of circulating transport chains with receiving shoes for receiving transverse and side-by-side stripe-shaped plates made of the porous material, a conveyor table also results, but due to the individually supported plates it brings greater strength and above all also the rational replacement of individual plates in the event of damage or the like. allowed.
  • a work table 1 has suction boxes 2 for pressurizing a support 4 forming the work surface 3.
  • a tool device 5, for example an ultrasonic cutting unit, is placed on the work table 1 and can be moved in a manner not shown for machining a workpiece placed on the support 4 over the work surface 3.
  • the support 4 consists of a porous material, for example of porous HD polyethylene.
  • the material can, as indicated in FIG. 1, be provided as a track 6a for a rotating conveyor belt 6, which can be moved step by step or continuously depending on the machining process to be carried out with a drive 7.
  • a kind of pallet 8 with a plate 8a inserted in a receiving frame 9 can also be produced from the porous material as a support 4, which pallet 8 is placed on the suction boxes 2 of the work table 1 as required.
  • a tensile fabric 10 can be glued on as reinforcement on the underside, so that the stresses caused by the workpiece or its processing are transmitted from this tensile fabric 10 to the frame 7 and the porous material is preserved.
  • a conveyor belt 11 made of a web 11a of the porous material as support 4, toothed belts 12 being provided on the edge as reinforcement for load absorption.
  • These toothed belts 12 can simultaneously serve as a guide for the conveyor belt and by interacting with the double toothed belt 13 of a toothed belt drive 14 also bring with it the drive of the conveyor belt 11, which is similarly achievable with rows of perforations instead of the toothed belt.
  • the circumferential path 11a also enables a fast, quick and easy change of the band, since this path with or without a toothed belt at its ends is only possible with adhesive tapes or the like. is connected and can therefore be easily opened and closed.
  • a conveyor belt 15 which consists of circulating transport chains 16 and transverse strip-shaped plates 15a made of porous material and fastened in a row on receiving shoes 17 of the transport chains 12.
  • the support 4 forming the work surface 3 which can be subjected to vacuum can be designed as desired, depending on the work table and processing sequence, it only has to consist at least partially of porous material which ensures the particular effectiveness of the vacuum application and the excellent holding of the workpieces placed thereon.
  • the material to be processed is anchored to a certain extent so that it is fiber-proof, so that it can be processed without difficulty and with the best results and in particular cut with ultrasound knives.
