Definitions
- the invention relates to a method for producing rolled-up Reinforcement 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 two Deflection rollers are guided through the assembly areas of the assembly machines connected and rolled up together with the rods connecting them in reeling stations and separated from the respective tape supply.
- the invention also relates to a Machine according to the preamble of claim 3.
- a machine of the type mentioned at the outset is known from the prior art is somewhat simpler and is suitable for semi-automatic operation.
- the prepared and cut to length reinforcement bars by hand using a the machine integrated cross conveyor in position with respect to the belts brought and also via a slide the welding machine in the Assembly zones fed.
- the work cycle of the machine is determined by time determined for the insertion of the bars in the cross conveyor and transport the cross conveyor is required up to the specified longitudinal position.
- the object of the invention is the known method and the known machine to improve in that the production time of the rod mat rolls is reduced.
- This object is achieved in a method of the type mentioned in that after the completion of a rod mat roll, another set of tapes in the same or in addition parallel strip running levels subtracted from a second set of supply rolls, in essentially opposite to the running 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 bar mat roll unrolling the tapes from the first set Supply roll starts.
- the two sets of tapes work alternately, so that after the strips 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 belts in the same belt running level from the supply rolls of the second Band set expire and essentially opposite to the direction of the first Run the set of tapes into the take-up 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 at 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 comprise, the bands in parallel planes perpendicular to the longitudinal extension of the Frame are feasible, and with one extending in the longitudinal direction of the frame Bar conveyor that extends over essentially the entire length of the frame.
- the bar conveyor is in the frame is integrated, that is, is supported by it, the frame rests on the Ground.
- the present invention differs from this known machine in that the frame in a floor frame and a spaced above its longitudinal ends and, if necessary, intermediate upper frame is subdivided into that based on the vertical longitudinal center plane of the frame, the tape supply roll on a Side of the top frame and the roll-up stations on the other side of the bottom frame are arranged that the welding robots are in this longitudinal median plane that at least two mutually feedable, essentially identical designs Rod conveyors with the same loading zones for connecting the rods with the Bands leading slides are provided.
- the top frame points to both opposite sides bearings for tape supply rolls and the bottom frame is equipped with roll-up stations on both sides.
- Most of the bar conveyors allow one further rationalization because unloading a bar conveyor and welding the thrown rod on the belts with the loading of the further rod conveyor and temporally overlap the rod transport taking place on it.
- the new machine is preferably mirror-symmetrical to the vertical longitudinal center plane built up, at least as far as the welding robots and the unwinding and reeling stations are concerned.
- 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 band supply rolls, upper band deflection rolls, the one or more bar conveyors, the slides and the upper electrodes of the welding units are arranged or supported.
- 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, two To arrange bar conveyors on one side of this plane of symmetry one above the other. Especially The combination of both alternatives is advantageous, so that the machine with four Bar conveyors is equipped.
- 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 of about 16 m on 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 forms the vertical longitudinal center plane of the machine.
- the upper frame 14 has a main side member 18, on which at a distance of e.g. 0.8 m identically trained tape guide units are arranged, as they are shown in the figure in the front view. On the left side of the main side member 18 there is one first unwind station 20 with a tape supply roll 22 and a tape guide roller 24.
- each Belt guide unit On the On the right side of the main longitudinal member 18 there is a second unwind station 26 Belt supply roll 28 and a belt guide roller 30 arranged underneath each Belt guide unit is assigned to a welding robot, 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 Bar mat roll 38 and a left-hand second roll-up station 40 for a corresponding one Staff Matt role. Furthermore, 12 guide rollers 42, 44 are mounted on the base frame and one cyclically immersing rod catcher 46 and the lower electrode 34.
- the described Components are the same in all belt guide units and since the belts are narrow, e.g. have a width of 3 cm, the belt guide units are also narrow.
- Each bar conveyor 48 is U-shaped in the area of each belt guide unit Guide member 50 assigned to a reinforcing bar 52 during transport the bar conveyor 48 stops and horizontally in the direction of the double arrows shown is drivable to the rod 52 laterally inwards over the rod conveyor 48 on a Slide slide 54, on which the rod 52 defined in one of the rod catches 46 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 in FIG Running direction slightly inclined. After completion of a rod mat roll 38, the Bands are cut off, then the bands 60 of the second unwind station 26 are unrolled, around the upper right deflection roller 30 and the lower left deflection roller 42 Roll-up station 40 performed.
- 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 into the assembly zone 56 defined by the rod catcher 46.
- the upper electrode 32 is located itself in the pulled-up state, as shown in the figure, can be removed from the bars 52 not be damaged. After positioning the respective rod 52 in the The mounting zone moves the upper electrode 32 down into contact with the rod and presses this in contact with the tapes 60 so that the welding operations occur simultaneously can be carried out.
