Definitions

the invention relates to a method for the production of rolled up Reinforcing bar mats, each consisting of a number of spaced parallel Sheet metal strips exist on which are located at individual distances from each other Arranged reinforcement bars are welded, the tapes in unwinding stations deducted synchronously from coaxial supply rolls, on straight lines between each two deflection rollers through rod assembly zones, from automatic assembly machines connected with rods and together with the rods connecting them in Roll-up stations are rolled up and separated from the respective strip supply.
EP 0 677 343 A1 shows such a method.
the rods are made from magazines straightened and cut to length in straightening and cutting machines program-controlled in a cross conveyor across the running levels of the belts in the predefined transverse position from which they slide into the Assembly zones of the machine arrive where it is welded to the belts become.
the machine has proven itself in practical use, but it is narrower the time required to remove the rod mat roll, to prepare the new one Roll and equipping the unwinding stations with new tape supply rolls the possible Performance result. Since this procedure is short as well as up to about 16 meters Long rod mat rolls are made, the tape consumption is on the individual Unwind stations differently, so that the machine stops every time one of the Supply rolls must be replaced.
the removal of the heavy and - as I said - up to 16 meters long rod mat rolls from the one behind the other in the direction of the rod lying reeling stations is only possible by means of complex hoists this removal process, the machine is not ready for production.
a machine of the type mentioned is known is somewhat simpler and is suitable for semi-automatic operation.
the work cycle of the machine is determined by time determined for the insertion of the bars in the cross conveyor and the transport on the cross conveyor is required up to the specified longitudinal position.
the object of the invention is that known methods and the known machine to improve in that the production time of the rod mat rolls is reduced becomes.
this object is achieved by that after the completion of a rod mat roll, another set of tapes in the same or subtract parallel belt running levels from a second set of supply rolls, essentially opposite to the direction of the first set of tapes by the Rod placement zones, there from the same placement machines with rods equipped and rolled up in a second set of rewind stations and that after Completion of the second rod mat roll, unrolling the tapes from the first set Supply rolls begin.
the two sets of tapes work alternately, so that after the tapes between the rod mat roll and are automatically cut off Tape supply rolls in the area of the assembly zones the old tapes are removed and the new tapes in the same tape running plane from the supply rolls of the second Band set expire and essentially opposite to the direction of the Run the first set of tapes into the reeling stations for the second set of tapes.
the invention further relates to a machine for the production of rolled up Reinforcement mesh, with an elongated frame, on which in longitudinal intervals Belt guide units are arranged, each of a tape supply roll, Belt deflection rollers, a welding robot and at least one belt rewind station include, the bands in parallel planes perpendicular to the longitudinal extent of the frame are guided, and with one in the longitudinal direction of the frame extending bar conveyor, which extends over substantially the entire length of the frame.
a Such a machine is shown in the prior art mentioned second in the foregoing.
the bar conveyor is integrated in the frame, that is, is supported by this, the Frame rests on the floor.
the Most of the bar conveyors allow further rationalization because the unloading of one Bar conveyor and welding the dropped bar to the belts with the Loading of the further bar conveyor and the bar transport taking place on it in time overlap.
the new machine is preferably mirror-symmetrical to the vertical Longitudinal center plane built, at least what the welding robots and the rolling and Reel stations affects.
the machine can be equipped with a Band set work, but is for retrofitting with the second band set designed so that the upper frame on both sides supports for Has tape supply rolls and the bottom with roll-up stations on both sides is equipped or retrofittable, and that the machine at least in terms of Tape supply rolls and the take-up stations are mirror images of the Placement zones containing the vertical symmetry plane arranged and / or is trained.
the top frame preferably comprises a main side member which is spaced apart extends above the assembly zones in the plane of symmetry, and on which the bearings for the tape supply rolls, upper belt deflection rolls, the bar conveyor or the, the Slides and the upper electrodes of the welding units arranged or stored are.
the two bar conveyors are preferably on both sides of the longitudinal plane of symmetry of the upper frame arranged on this. But it is also within the scope of the invention arrange two bar conveyors on one side of this plane of symmetry one above the other.
the figure shows a schematic front view of the machine in the longitudinal direction of the Reinforcement bars seen.
the machine has a base frame 12 and a spaced one above it Set up 14. Both frames 12, 14 are approximately the same length and have a length from about 16 m to what is the greatest length of road transportable Corresponding bar mat rolls. Both frames 12, 14 are mirror-symmetrical to one Plane of symmetry 16 formed which is the vertical longitudinal center plane of the machine forms.
the upper frame 14 has a main side member 18, on which at a distance from e.g. 0.8 m of the same design tape guide units are arranged as they result from the figure in the front view.
On the left side of the Main longitudinal member 18 is a first unwind station 20 with a Tape supply roll 22 and a tape guide roller 24.
the main longitudinal member 18 On the right side of the The main longitudinal member 18 is a second unwind station 26 with a tape supply roll 28 and a belt deflection roller 30 arranged underneath.
Each belt guide unit is a welding robot is assigned, which consists of an upper welding electrode 32 and a lower welding electrode 34.
the axes of the welding electrodes 32, 34 lie in the plane of symmetry 16.
the base frame 12 supports a right-hand first roll-up station 36 for one
the components described are the same in all tape guide units because the bands are narrow, e.g. have a width of 3 cm are also Belt guide units narrowly built.
Each bar conveyor 48 is U-shaped in the area of each belt guide unit Guide member 50 associated with a reinforcing bar 52 during transport stops on the bar conveyor 48 and horizontally in the direction of the double arrows shown is drivable to the bar 52 laterally inwards over the bar conveyor 48 to slide a slide 54 on which the rod 52 fits into one of the rod catchers 46 defined assembly zone 56 arrives.
the tapes 60 of the first set of tapes run from and around the supply rolls 22 upper left pulley 24 and lower right pulley 44 around to the first Roll-up station 36.
the belt sections are between the two deflection rollers 24, 44 rectilinear and occur in the plane of symmetry 16 with the lower welding electrodes 34 in contact.
These rectilinear band sections 62 run with respect to the horizontal slightly inclined in the direction of travel.
the tapes 60 of the second unwind station 26 unrolled around the right upper deflection roller 30 and the left lower deflection roller 42 led around to the roll-up station 40.
This also results in between the two Deflection rollers 30, 42 straight band sections 64 which, in contrast to the Band sections 62 of the first set of bands are inclined to the left. Between two straight band sections 62, 64 an acute angle in the range of 5-10 ° educated.
the outlet ends of both chutes 54 one Height distance at least equal to the diameter of the strongest reinforcing bars 52 exhibit.
the reinforcement bars 52 from all four bar conveyors 48 thus slide in the assembly zone 56 defined by the rod catchers 46.
the upper electrode 32 is in the raised state, as shown in the figure, so it can be from the rods 52 are not damaged. After positioning the respective rod 52 in the loading zone, the upper electrode 32 descends into contact with the rod and presses it into contact with the bands 60 so that the welding operations can be performed simultaneously.
