Definitions

  • the invention relates to a method for producing a reinforcement bundle, which consists of at least two mutually parallel reinforcement bars that touch each other over the entire length, and a device for carrying it out.
  • the bundling of reinforcing bars is particularly favorable for the replacement of single bars of larger diameter, for example from a diameter of 18 mm, whereby the bundling of two, three or four bars brings particular advantages. Since the diameter graduation is generally 1 mm, for larger diameters 2 mm is, a large number of single bars of larger diameter must be replaced by reinforcement bundles.
  • the invention has now set itself the task of creating a method which is suitable by means of a simple, rationally usable device for producing reinforcement bundles of any number of bars and any diameter, in preferred embodiments the diameter of the bars also within the bundle are different. and their lengths can be adapted to the course of the bending moment line.
  • bundles of two, three or four bars of the same and different diameters and the same or different lengths should be able to be produced in a single automatic production system without significant downtimes, the overall system, in particular the number of reels, being economically justifiable on the reinforcement bundles moved about adjusted extent.
  • this object is achieved in that from a number of reinforcement wires wound on reels, which is at least one larger than the number of bars in the bundle of reinforcements to be produced, a number of reinforcement wires corresponding to the number of bars in the bundle is selected by feed devices, a welding device fed, welded together at least some places and cut to the desired length.
  • a device suitable for this purpose is characterized by a supply part with reinforcement wires wound on reels and with straightening devices assigned to them, by a selection unit, by a feed unit with controlled selectable feed devices, by an immediately adjoining cutting unit and by a welding unit, the number of reels being at least one is greater than the number of reinforcing bars of the bundle and the ends of all reinforcing wires constantly protrude into the selection unit in which the selected reinforcing wires can be grasped by the feed devices, each feed device preferably consisting of a drive roller and a pinch roller, each drive roller on its own , drivable drive shaft is arranged.
  • all reinforcement wires are therefore constantly available in the device, of which only those are selected and processed which are required for the reinforcement bundle to be produced. If, for example, two-bar reinforcement bundles are required, Two of four reinforcement wires inserted into the selection device can be gripped and welded together. The changeover to the production of three-bar bundles is therefore limited to the activation of an additional existing reinforcement wire, which is integrated into the processing process. In order to produce a four-bar bundle, the fourth reinforcing bar resting in the selection device is also included in the production.
  • a device with four reinforcement wires of the same thickness is therefore already able to produce three different types of bundles with bars of the same length in any length. If the reinforcement bundles are to be approximated to the torque curve, so that the lengths of the reinforcement bars are staggered, this can be achieved in that the selected reinforcement wires are fed from the individually controllable feed devices to the welding device at the same feed rate and the feed of the selected reinforcement wires is interrupted in reverse order in time, each reinforcement wire being cut off immediately after the interruption of its feed.
  • the cutting unit has a number of cutting devices which corresponds to the maximum number of reinforcing bars of the reinforcement bundle and which can be actuated individually in a controlled manner.
  • the same device is therefore capable of bundles of two, three or four bars of any length to generate, with the rod lengths adapted to the torque curve from bundle to bundle and therefore different.
  • the reinforcement bars have different diameters in the individual bundle.
  • three different two-bar bundles, two different three-bar bundles and one four-bar bundle i.e. a total of six different types of bundles, each in any length adapted to the course of the moment, can be produced if only reinforcement wires with successive diameters Diameters can be combined.
  • the method suitable for this purpose provides, according to the invention, that the reinforcement wires wound on reels are assigned to the feed devices according to increasing diameter, that from the row of reinforcement wires a group of adjacent reinforcement wires corresponding to the number of bars of the bundle is detected by the feed devices and fed to the welding device, whereby no significant design change of the device described above is required. If the diameters are combined as desired, six different two-bar, four three-bar and one four-bar, i.e. a total of eleven different bundles can be produced, each in any length. The resulting advantage is multiplied particularly when the number of reels is increased.
  • the reinforcement wires are provided in the common mean diameters between five and sixteen millimeters, each with a difference of one millimeter, reinforcement bundles are produced, which can replace all the usual single rods, the extent of the stock part being less than the usual width of mesh welding machines.
  • the feed unit can have a number of feed devices corresponding to the total number of reinforcing wires, which can be used individually controlled. So only those are switched on, which should convey the desired reinforcement wires.
  • a further embodiment of a device provides that the feed unit has a number of feed devices corresponding to the maximum number of reinforcement bars of the reinforcement bundle, all drive rollers and all pinch rollers being combined to form a feed block. and both feed blocks can be displaced in two directions in a plane perpendicular to the working direction and groups of selected reinforcing wires, which project into the selection device next to one another in an ordered manner according to increasing diameter, can be assigned. In this embodiment, significantly fewer feed devices are required, which can be adjusted jointly between the individual feed positions. If, for example, the production of a maximum of four-bar bundles is planned, four feed devices are provided in the feed block, each of which in turn can preferably be driven individually in order to also be able to produce two- and three-bar bundles.
  • the ends of the reinforcement wires have two common tangential planes which enclose an angle and each feed block can be displaced parallel to a tangential plane. If the center plane of all reinforcement wires runs horizontally, the displacement paths of the feed blocks to the horizontal each include half the angle of the two tangential planes.
  • the device according to FIG. 1 is equipped with a storage part 1, in which twelve reels for reinforcing wires 5 to 16, each of which has a different diameter, are arranged in two rows.
  • Each reel is equipped with a conventional balancer arm, not shown or shown, and a spring-loaded brake that is released when the balancer arm is actuated.
  • the reels for the reinforcement wires with a diameter from 12 mm, i.e. for the wires 12 - 16, are additionally equipped with a hydraulic driver.
  • the selection unit 2 is assigned a feed unit 3, which has a plurality of feed devices 19, 20, each consisting of a drive roller 19 and a pinch roller 20, each of which, individually controlled, can move one of the ends of the reinforcing wires 5 to 16 projecting into the selection unit (Fig. 2,3).
  • a cutting unit 17 which consists of the maximum number of rods of the bundle corresponding, individually controlled scissors. The design of these scissors essentially corresponds to that used in the manufacture of lattice girders or structural steel mats, and is therefore not shown in more detail.
  • the cutting unit 17 is followed by a welding unit 4 which combines the rods into bundles and ejects them at the end of the device.
  • the direction of work corresponds to arrow A.
  • the number of reels and thus the reinforcement wires 5-16 in the illustrated embodiment is three times the maximum number of bars to be bundled. Generally it is at least one bigger. This means that more and more reinforcement wires 5 - 16 are available in the selection device 2 than are required for the production of a bundle.
  • the number and the diameter of the reinforcing wires 5 to 16 can therefore be selected with the aid of the feed devices 19, 20.
  • twelve reinforcement wires 5 to 16 are shown, the ends of which protrude into the selection unit 2.
  • a feed device 19, 20 is assigned to each of these reinforcement wires, the drive shafts 21 of the drive rollers 19 being individually drivable.
  • the reinforcing wires 5 to 16 are arranged in one plane with increasing diameter, starting from the left in the drawing. Since bars with adjacent diameters are usually bundled, for example to produce a bundle according to FIG. 4, the feed devices are set in motion, between which the reinforcement wires 7, 8, 9 are clamped. If the bundle of staggered bars according to FIG. 6 is to approach the course of the bending moment, the feed device assigned to the reinforcement wire 8 begins with the feed.
  • the feed device assigned to the reinforcement wire 7 and finally the feed device assigned to the reinforcement wire 9 are set in motion, all feed devices 19, 20 running at the same speeds, in particular using the cycle method.
  • the on this Reinforcement wires reaching the welding unit 4 are welded to one another at least in some places.
  • the advance of the reinforcement wire 9 is first stopped and at the same time cut off by a pair of scissors of the cutting unit 17 assigned to it.
  • the feed of the wires 7 and 8 is continued, as is the welding.
  • the feed of the wire 7 is stopped as soon as its pre-calculated length is reached and another pair of scissors assigned to it cuts it off.
  • the feed of the wire 8 is continued up to the total length of the bundle, missing welds being carried out.
  • the reinforcement wire 8 is also cut by a further, individually controlled pair of scissors and the finished bundle is ejected from the device.
  • the procedure for producing a bundle according to FIG. 5 is the same, except that a total of four reinforcement wires 7, 8, 9, 10 are processed.
  • This version is also suitable for bundling non-adjacent reinforcement wires, since any feed device can be set in motion by the individual control.
  • the feed unit shown in FIG. 3 shows three feed devices 19, 20, which are combined in two feed blocks 22.
  • This feed unit can be used for production systems in which only two- or three-bar bundles are to be produced, in which adjacent diameters are used. If the production of four-bar bundles according to FIG. 5 is also provided, each feed block 22 is equipped with four rollers, so that four feed devices 19, 20 can be used.
  • the reinforcement wires 5 to 16 are in turn arranged with increasing diameter in the selection unit 2, starting from the left, the common center plane running horizontally.
  • the reinforcement wires 5 to 16 are aligned so that they have two common tangential planes, which enclose the angle plate with each other.
  • Each feed block 22 is displaceable in the direction of arrow B on a guide track 23 which is height-adjustable in the direction of arrow C, each guide track 23 running parallel to a tangential plane and therefore the angle with the horizontal includes.
  • the feed devices 19, 20 therefore each grip a group of adjacent reinforcement wires 5 to 16, and because of the oblique guideways 23, no individual adaptation to the different diameters of the reinforcement wires is necessary.
  • the drive rollers 19 of the feed devices can in turn be driven individually, so that any combination of reinforcement wires is again possible within each group.
  • the guideways 23 are moved apart, the feed blocks 22 are moved to the desired position and the guideways 23 are brought closer together again, whereupon the feed of the changed group of reinforcement wires can be started in the manner described for FIG. 2.
  • the method according to the invention enables, by means of a relatively simple device, the automatic production of reinforcement bundles in a large number of different combinations of bars, lengths and diameters without time-consuming changes the system are necessary.
  • the system is advantageously controlled by means of electronic data processing, by means of which the reinforcement wires are automatically selected, the feed devices assigned to these selected wires are used, and the shears of the cutting unit assigned to the selected wires are used.
  • the preferred embodiment of the invention in which only reinforcement wires with different diameters are used, provides a further advantage of great importance.
  • about a third of the total reinforcement runs up to the support, since the reinforcement wire 8 with the middle cross section is the longest. If a higher proportion is required, wire 9 becomes necessary; if a lower proportion is required, wire 7 is provided in its entire length and the others are shortened.
