Definitions

  • the invention relates to a door leaf for a ceiling link or roller door consisting of a hollow profile formed by two sheet metal shells, the cavity of which is filled with a heat-insulating mass, with joint elements provided on the long sides of the hollow profile, and with two next to the two joint elements over the length of the Gates extending columns, which are bounded by legs bent towards the cavity side.
  • Such a door leaf is known (DE-OS 27 35 899).
  • the two sheet metal shells are provided with bends on their long sides provided with the joint elements. In the area of the bends there is a gap between the two sheet metal shells, through which a cold bridge is avoided. The gap is bridged by a plastic membrane that has a low thermal conductivity.
  • the two sheet metal shells are held together in that the heat-insulating foam mass engages behind the bends.
  • the invention has for its object to design the door leaf of the type described above so that it is suitable for a continuously running automatic manufacturing process.
  • Characteristic a makes it possible to press in the gaps by means of cutting rollers, while the door leaf is supported with the other side against the pressure of the split rollers by simple contact, for example on a lower belt, without the need for special holding means to be carried. This is not possible if, as in the known door leaf, the gaps are provided on the long sides provided with the joint elements.
  • Feature b prevents the part of the sheet metal shell in question, which is located between the gaps, from being bent by the deformation pressure of the splitting rollers; moreover, this part cannot fall off the heat-insulating mass when the adhesive strength decreases.
  • Feature c) also contributes to the production of the gaps by a chipless pressing in by means of splitting rollers, which are particularly suitable for a continuously running automatic manufacturing process.
  • the sheet metal shell to be provided with the gaps can be attached next to the two on the inside of the cavity Notches each in the middle between the notches on the side facing away from the cavity, another notch can be made. This further notch makes it easier to press in the gap with the splitting rollers.
  • a preferred embodiment of the method for producing the door leaves according to the invention provides that two metal strips, which are wound on metal strip rolls, are drawn off from an infeed frame and are formed in a two-tier roll forming machine to form the hollow metal profile.
  • this roll forming machine one of the strips is provided with the beads and the notches located therein.
  • the undersides of the pre-profiled strips are then pressed together by pressure rollers and their upper sides are held apart by an expanding lug or an expanding roller.
  • the outlet nozzle of a plastic foam machine is attached, through which a curable plastic foam material, for example polyurethane, is filled between the belts.
  • This plastic foam mass is the heat-insulating material.
  • the closed metal strips pass through an alignment section before they are passed on to the curing section in which the plastic cures.
  • the cutting machine is equipped with a floating saw, which allows the moving metal strip to be cut into individual metal hollow profiles of the desired length. In order to avoid a jam inside this saw, the sawn-off individual pieces are pulled out of the cutting machine at an accelerated rate.
  • a hollow metal profile is gripped by a lifting pliers at both ends and moved into a position lower by the width of this hollow metal profile. In this lower position, it is then gripped and held in place by holding forceps. After the holding tongs have been accessed, the lifting tongs move back into their upper position so that they are ready for operation again.
  • the next following hollow metal profile is then inserted by means of corresponding drive rollers with its lower joint element into the upper joint element of the previous hollow metal profile. This last arrived hollow metal profile is then gripped by the lifting pliers so that this cycle can be repeated.
  • the nested metal hollow profiles are laterally guided to a milling system by means of a cross conveyor belt.
  • slots are milled into the heat-insulating compound filling the cavity on the end faces of the hollow metal profiles, so that end pieces with their mounting lugs can be attached to these slots.
  • These end pieces are pressed on in a subsequent process step.
  • the individual door leaves which are already pushed together to form a roller door curtain.
  • the interlocking door leaves are wound into a bale.
  • paper is inserted between the individual layers of the door leaves to protect the door leaves against scratching. This paper is pulled off a roll of paper.
  • the device used to carry out the manufacturing method according to the invention is provided in connection with the individual exemplary embodiments, insofar as this does not already result from the description of the manufacturing method.
  • FIG. 1 shows a cross section through a door leaf 1 according to the invention. It consists of a hollow metal profile which is formed by two interlocking lamella leaves 20, 21. These lamella blades 20, 21 have different strengths.
  • the lamella leaf 20, which formed the outer shell of the profile body, has the greater wall thickness because it has to have the necessary stability and tensile strength of the door leaf.
  • the thinner lamella leaf 21 forms the cavity wall 7 lying on the inside of the gate. In this cavity wall 7 beads 13 are fitted, within which the gaps 9 run.
  • the gaps 9 are delimited by two legs 12 bent into the cavity 3.
  • the bending edge of the legs 12 runs along the notches 15.
  • the column 9 are in close to the narrow sides of the cavity 10, so that as large a part of the cavity wall as possible. 7 lies isolated.
  • the cavity 3 of the door leaf is filled with a heat insulating mass.
  • FIG. 2 shows that two pairs of notches 15 are provided on the surface 17 of the wall 7 facing the cavity 3 to form the gaps 9.
  • a further, deeper notch 16 is made centrally between the two notches 15 of each pair. All three notches 15, 16 are located within a bead 13 which protrudes toward the cavity 3. If a tool is pressed into the notch 16, the notch 16 tears open to a gap 9, as shown in FIG. 1.
  • Fig. 3 shows how two articulated elements of two door leaves interlock.
  • FIG. 4 shows a perspective view of a door leaf according to the invention.
  • the column ? 9 are bridged by individual, narrow webs 11. These narrow webs bring about a mechanically firm connection of the cavity wall 7 facing the interior of the gate to the joint elements.
  • the gaps 9 lie within a bead 13.
  • the gaps 9 are delimited by legs 12 which are bent inwards to the cavity 3.
  • the lower part shows that the gap 9 can also be continuous.
  • an inlet scaffold 30, on which there are two metal tape rolls 31, 32, metal tapes 33, 34 removed.
  • This inlet scaffold is shown in FIGS. 10 and 11.
  • the metal strips 33, 34 are drawn off from the infeed stand via rollers 302, 303 of a roller stand 301.
  • the belts are rotated through 90 ° and drive rollers 38, which are arranged at the entrance of a two-tier roll forming machine 35, are driven.
  • the thinner metal strip 33 runs through a beading station, in which it is provided with a continuous beading by appropriately designed rollers 39.
  • the notching station in which the metal strip 33 is provided with the notches 15, 16 shown in FIG. 2, is located behind the beading station.
  • the notches are pressed there with the aid of rollers 37 which are equipped with cutting edges.
  • the metal strips 33, 34 are then pre-profiled in subsequent rollers 36. This is shown in FIGS. 5 and 6.
  • the metal strips then arrive at a second roll forming machine 40, which is shown in more detail in FIGS. 13 and 14.
  • pressure rollers 41 At the inlet of this second roll forming machine 40 there are pressure rollers 41, in which the undersides of the pre-profiled strips 33 J 34 are pressed together. This is shown in more detail in FIG. 7.
  • the second roll forming machine 40 also has an expanding roller 42, with which the upper sides of the pre-profiled strips 33, 34 are kept spread.
  • This curing section 62 is shown schematically in the left part of FIGS. 15 and 16. From the curing section, the endless hollow profile formed from the metal strips 33, 34 passes into a length measuring device 70. This length measuring device is used to control the cutting machine 80, with which the endless profile is sawn into individual pieces. The length measuring device is equipped with a spring-loaded measuring wheel running on the profile and with length and piece counters. The endless profile then passes from the length measuring device into a splitting station 75, in which the notches 16 to columns 9 are opened with splitting rollers 76. The indentation of the column is clarified in FIG. 8. The profile is held by a counter roller 78 when the split roller 76 presses in the column 9.
  • the split roller 76 can be lifted off the cavity wall 7 of the profile, so that individual gaps with webs 11 lying between them can be produced.
  • Behind the splitting station is a scaffolding 77 which advances the endless profile to a cutting machine 80.
  • This cutting machine 80 is used for the flying cutting of the endless profile.
