Definitions

  • the invention relates to a device for loading a lattice 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 which can be pivoted transversely to the feed direction in the feed plane.
  • a device for feeding a group of parallel, upright standing flat iron strips to a grating welding machine is known.
  • 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 create 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 fixedly connected to the insertion member and can be pivoted individually transversely to the feed direction, the free ends of which at 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 direction of advance and which contains guide grooves distributed over its circumference, one of the guide grooves being able to select any desired spacing Feeding organs enabled, whereas the remaining guide grooves are arranged along the longitudinal axis of the division revolver according to predetermined standard distances of the feeding organs.
  • 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 to say while 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 wire mesh 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 lattice mats or of flat strips for the production of gratings.
  • FIG. 1 shows a schematic side view of a device according to the invention
  • FIG. 2 shows a schematic top view of FIG. 1 and FIG. 3 shows a perspective view of a part of the device.
  • longitudinal elements L e.g. Longitudinal wires, or the like from a feed carriage, not shown, in the manufacture of a mesh mat. necessary number as well as in the transverse distance corresponding to the grid mat structure in the direction of arrow P insertion funnels 1.
  • 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 defined by the feed paths of the longitudinal elements level 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 division of the electrodes of the grid welding machine.
  • the insertion funnels 1 are pivotally connected about an axis 2 in the direction of arrow P 1 perpendicular to the feed plane with a frame 3 which is longitudinally displaceable in the direction of arrow P and adjustable in height in the direction of arrow P 1 on a base frame 4 which is longitudinally displaceable in the direction of arrow P 4 is arranged.
  • 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 P ⁇ 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 in each case with a welding electrode 8 of the downstream welding machine and is fastened longitudinally on a lifting beam 9 in the direction of arrow P_ and can be shifted in the direction of arrow P.
  • 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 P g .
  • the number of feed tubes 7 expediently corresponds to the largest number of longitudinal elements that can be processed in the welding machine.
  • a feed pipe 7 is fixed to the lifting beam S by means of a releasable clamping device 12.
  • the lifting beam 9 is mounted on the base frame 4 in a height-adjustable manner in the direction of the arrow P q , as a result of which the position of the feed pipe 7 can be adjusted to different diameters of the longitudinal elements.
  • the feed tube 7 is also supported on a dividing turret 13 which can be rotated in the direction of the arrow P 1Q about an axis running transversely to the feed direction.
  • the dividing turret 13 contains several 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 fastened 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 pipe 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 in the direction of arrow P p against the feed direction P of the longitudinal elements L as far from 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.
  • the base frame 4 is also retracted in the direction of arrow P 4 against the feed direction P of the longitudinal elements, so that the feed tubes 7 move away from the welding electrodes 8 of the welding machine in order to distribute the subsequent adjustment of the welding electrodes 8 to the desired longitudinal element to enable.
  • the clamping device 12 is released and the feed tubes 7 are optionally retracted in the direction of the arrow P ß against the feed direction P.
  • the base frame 4 is pushed back into its starting position in the direction of the arrow P.
  • the feed pipes 7 are lifted out of the guide grooves 14, 14 "of the division turret 13 and this is rotated in the direction of arrow P 1Q in accordance with the desired division of the longitudinal elements in the grating to be made such that the corresponding row of guide grooves 14, 14 'or endless guide groove 14 is brought into the overhead working position.
  • feed pipes 7 are moved by a corresponding transverse displacement in the direction of the double arrow P ? and subsequent longitudinal displacement in the direction of arrow P ,. Centered on the welding electrodes 8 by means of centering aids (not shown) and fixed by means of the clamping device 12. Feed pipes 7 which are not required can optionally be pushed into a so-called parking position at the edge of the production level.
  • the closure cover 11 is moved by pivoting in the direction of the arrow P 'into the open position shown in broken lines and the frame 3 is pushed back into its original starting position in the direction of the arrow P ⁇ .
  • Corresponding commands are given by the welding machine controller to signal displays (not shown) which are expediently attached to the insertion funnels 1 in order to indicate to the operator which of the Insertion funnels 1 for the type of lattice mat to be produced are fed with longitudinal elements L from the feed carriage (not shown) and which of the feed channels K which
  • Feed pipes 7 must be assigned. Such an assignment is made in that the corresponding insertion funnel 1 with its two

  • position D in a so-called double welding, in which two longitudinal elements L are welded without transverse spacing together with the transverse elements, for example transverse wires, two feed channels K are inserted jointly between the guide plates 15 of a feed pipe 7.
  • 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 mesh mat, not all insertion funnels 1 are required, these insertion funnels 1 are not assigned to a feed tube 7 and are not loaded with longitudinal elements L from the feed carriage. Finally, the feed channels K are closed from above by swiveling the closure cover 11 down in the direction of the arrow P fl in order to prevent the longitudinal elements from escaping in this direction as well. For those cases in which the feed pipes 7 are to be fed directly from the feed carriage, all feed channels K can become inoperative by lowering the frame 3 in the direction of arrow P 3 from the feed plane EE. In the embodiment variant of the device shown in FIG. 2, 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. Instead of the Guide elements 15 is about an axis 17 in the direction of
