Definitions

  • the invention relates to a device for loading a grid welding machine with longitudinal elements, with organs arranged in a feed plane transverse to the feed direction with constant mutual spacing for introducing the longitudinal elements into feed channels pivotable in the feed plane transverse to the feed direction.
  • a device for feeding a family of parallel, upright standing flat iron strips to a grating welding machine is known.
  • a set of distributor pipes is interposed between a set of guide tubes which cannot be changed with respect to the mutual spacing, the inlet-side ends of which are arranged at a fixed distance from one another corresponding to the spacing of the guide tubes and which are pivotally mounted so that the mutual distance between their outlet ends can be selected, these tubes being fixable in the selected position.
  • the distributor pipes define feed channels with fixed, unchangeable widths and can only be pivoted as a whole unit. Due to this design, the swivel range of each distributor pipe is limited by the swivel range of the adjacent distributor pipe. In addition, a constant lower limit for the spacing of the longitudinal elements from one another is predetermined by the constant width of the distributor pipes.
  • the invention aims to provide a loading device in which both the number and the mutual spacing of the longitudinal elements can be freely selected with the aid of variable feed channels.
  • the device according to the invention is characterized in that each feed channel is laterally delimited by guide elements which are firmly connected to the insertion member and can be pivoted individually transversely to the feed direction, the free ends of which on the inlet side of downstream feed elements of the welding machine can be detachably fixed by means of guide devices attached to these feed elements, the feed elements which can be displaced transversely to the feed direction being adjustable to freely selectable transverse distances, and each feed element being connectable to one or more feed channels via the guide elements.
  • the insertion members formed by funnels are pivotally mounted with their guide elements on an axis in the direction perpendicular to the feed plane of the longitudinal elements.
  • the guide elements preferably consist of wear-resistant spring steel strips.
  • the guide devices are formed by closure flaps which can be pivoted perpendicularly to the feed plane of the longitudinal elements.
  • a further development of the invention is characterized in that the feed elements can be supported and fixed in these guide grooves by means of a dividing turret which can be rotated about an axis running transversely to the feed direction and which contains guide grooves distributed over its circumference, one of the guide grooves allowing freely selectable distances between the feed elements , whereas the other guide grooves are arranged along the longitudinal axis of the division revolver according to predetermined standard distances of the feed elements.
  • the device according to the invention makes it possible to design the position of the side walls of the feed channels relative to one another and the width of the feed channels differently depending on the movement and position of the guide elements.
  • the ranges of movement of all side walls of the feed channels are in interaction with the side walls of the adjacent feed channels, that is, by changing the width of the respective, adjacent feed channel, expandable and optimally adaptable to different longitudinal element diameters and longitudinal element divisions.
  • the longitudinal elements can thus be transferred from feed positions with fixed, unchangeable transverse distances to feed elements with arbitrarily adjustable transverse distances, which are used, for example, in welding machines for the production of lattice mats with any desired longitudinal wire pitch.
  • the longitudinal elements can have any cross-sectional shape, that is to say, for example, consist of round wires for the production of mesh mats or of flat strips for the production of gratings.
  • the device according to the invention makes it possible to feed longitudinal elements in the form of single and double elements to the feed elements of the welding machine.
  • longitudinal elements L e.g. Longitudinal wires, from a feed trolley, not shown, in the number necessary for the production of a mesh mat or the like.
  • feed funnels 1 are fed.
  • the feed paths of the longitudinal elements L are aligned with the openings of the insertion funnel 1. Only one longitudinal element L is fed to each insertion funnel.
  • the insertion funnels 1 lie parallel to the welding line S of the welding machine next to one another in the feed plane defined by the feed paths of the longitudinal elements EE.
  • the number of insertion funnels 1 suitably corresponds to the largest number of longitudinal elements L that can be processed by the downstream welding machine.
  • the mutual distance between the insertion funnels 1 is constant in each case and suitably corresponds to the smallest possible basic pitch of the electrodes of the grid welding machine.
  • the insertion funnel 1 are pivotally connected about an axis 2 in the direction of arrow P1 perpendicular to the feed plane with a frame 3 which is longitudinally displaceable in the direction of arrow P2 and height-adjustable in the direction of arrow P3 on a base frame 4 which is longitudinally displaceable in the direction of arrow P4.
  • each insertion funnel 1 facing the welding machine two guide elements 5 are attached laterally, which are upright perpendicular to the feed plane E-E and limit a feed channel K for one longitudinal element L.
  • the guide elements 5 are e.g. from wear-resistant spring steel strips, which can be pivoted at their free ends in the feed plane E-E in the direction of the arrow P5 transversely to the feed direction P.
  • the length of the guide elements 5 is selected so that, in the event of extreme lateral pivoting of the same, longitudinal elements with the largest dimensions to be processed in the downstream welding machine can slide in the feed channels K without permanent deformation, without excessive friction losses occurring.
  • An end plate 6 fastened to the frame 3 limits the feed channels K at the bottom and thus prevents the longitudinal elements L from falling out of the channels.
  • Each feed channel K opens into a tubular feed element 7, which is aligned with a welding electrode 8 of the downstream welding machine and is longitudinally displaceable on a lifting beam 9 in the direction of arrow P6 and can be moved in the direction of arrow P7.
  • the feed channel K is also covered by a cover 11 which can be pivoted about an axis 10 in the direction of the arrow P8.
  • the number of feed tubes 7 appropriately corresponds to the largest number of longitudinal elements that can be processed in the welding machine.
  • a feed pipe 7 is fixed to the walking beam 9 by means of a releasable clamping device 12.
  • the walking beam 9 is mounted on the base frame 4 in a height-adjustable manner in the direction of the arrow P9, as a result of which the position of the feed pipe 7 can be adjusted to different diameters of the longitudinal elements.
  • the feed pipe 7 is also supported on a dividing turret 13 which is rotatable in the direction of the arrow P 10 about an axis extending transversely to the feed direction.
  • the dividing turret 13 contains a plurality of centering grooves 14, 14 ′ distributed around its circumference, which are arranged in rows parallel to the longitudinal direction of the dividing turret 13. In this way, a plurality of fixed, predetermined standard distances between the feed pipes 7 and thus standard divisions of the longitudinal elements L can be set quickly and reproducibly.
  • guide plates 15 are attached on both sides of the feed tube, which lengthen the feed tube 7 in the direction of the guide elements 5 and enclose them in the working position.
  • a V-shaped longitudinal groove and suitable spring elements are provided in the feed tube 7, which press the longitudinal elements L into this groove and thus ensure a precisely reproducible, exactly fixed position of the longitudinal elements as they are fed into the welding machine.
  • the frame 3 is so far from in the direction of arrow P2 against the feed direction P of the longitudinal elements L. Working position withdrawn until the guide elements 5 detach from the guide plates 15 of the feed pipes 7 and can spring back into their starting position parallel to the feed direction P. Subsequently, the base frame 4 is also retracted in the direction of the arrow P4 against the feed direction P of the longitudinal elements, so that the feed tubes 7 are removed from the welding electrodes 8 of the welding machine in order to enable the subsequent adjustment of the welding electrodes 8 to the desired longitudinal element division.
  • the clamping device 12 is released and the feed pipes 7 are optionally retracted in the direction of the arrow P6 against the feed direction P.
  • the base frame 4 is pushed back into its starting position in the direction of the arrow P4.
  • the feed pipes 7 are lifted out of the guide grooves 14, 14 'of the dividing turret 13 and this is rotated in the grating to be produced depending on the desired division of the longitudinal elements in the direction of the arrow P10 such that the corresponding row of guide grooves 14, 14' or the endless guide groove 14th is brought into the working position above.
  • feed tubes 7 are centered on the welding electrodes 8 by means of a corresponding transverse displacement in the direction of the double arrow P7 and a subsequent longitudinal displacement in the direction of the arrow P6 and are fixed by means of the clamping device 12.
  • Feed pipes 7 that are not required can optionally be pushed to the edge of the production level in a so-called parking position.
  • the feed pipes which are loaded with only one longitudinal element L are designated 7 ', it also being shown that longitudinal elements of different diameters can be fed. Since, in many cases, depending on the desired type of grid mat, not all of the insertion funnels 1 are required, these insertion funnels 1 are not assigned to a feed tube 7 and are also not loaded with longitudinal elements L from the feed carriage. Finally, the feed channels K are closed by swiveling down the closure lid 11 in the direction of the arrow P8 from above in order to prevent the longitudinal elements from escaping in this direction as well.
  • all feed channels K can become inoperative by lowering the frame 3 in the direction of arrow P 3 from the feed plane E-E.
  • the insertion funnels 1 and also the guide elements 5 cannot be pivoted in the direction perpendicular to the feed plane of the longitudinal element group.
  • the Guide elements 15 is a pivotable about an axis 17 in the direction of arrow P11, U-shaped, open bottom closure flap 16 attached to the entrance of each feed tube 7.
  • the closure flap 16 is now initially pivoted up in the direction of the arrow P 1, after the steps described above, the guide elements 5 are corresponding to the desired assignment laterally pivoted in the direction of arrow P5 and then fixed in position by pivoting back the flap 16 in the direction of arrow P11. Thereafter, all the feed channels K are closed again by swiveling the closure lid 11 down in the direction of the arrow P8.
