Definitions

  • the invention relates to a device for preserving cavities according to the preamble of the main claim.
  • a known device emerges from DE-OS 26 57 533.
  • the spray nozzles are placed by the worker on a spray gun and inserted into the respective cavity of the vehicle body.
  • the spray pattern of each spray nozzle is matched to the shape of the respective cavity associated with it.
  • the spray nozzle has a positioning stop. The position and direction of the nozzle head in the cavity are determined by its contact with the hollow body. The worker initiates the spraying process, while the spraying duration is controlled independently of the worker.
  • Another disadvantage of this known system is that separate positioning stops must be provided on the spray nozzles for each body type.
  • the object of the invention is therefore to provide a device which allows further automation of the cavity preservation, in particular one which is independent of the worker, the preservation process takes place in a shorter time and can be easily converted to other body types or vehicle models.
  • Such a device is particularly well suited for preserving the cavities of vehicle bodies and vehicle parts such as axle supports, etc. However, it is not restricted to this.
  • the positioning device consists of a plurality of cylinder-piston units with holding mandrels which engage in corresponding holders of the vehicle body. It goes without saying that the position of the positioning device in the horizontal plane, that is to say in the x and y directions, must remain unchanged in relation to the support frame.
  • the carrier frame can perform the vertical movement. However, it is a corresponding one Movement of the positioning device is also possible. Furthermore, this movement can be carried out partly by the support frame and partly by the positioning device, for example by lowering the body and then moving the spray nozzles into the cavities.
  • the vehicle body has one or more openings for the passage of the spray nozzles for each cavity.
  • the hole pattern of all openings corresponds to the arrangement of the spray nozzles on the support frame. Due to manufacturing tolerances, the passage openings can shift somewhat, so that the associated spray nozzle no longer hits precisely when it starts up. It is therefore advantageous to resiliently mount the spray nozzles on the nozzle carrier so that they can compensate for these manufacturing tolerances.
  • the spray system cannot perform its function.
  • the spray nozzles can be damaged. It is therefore expedient to provide means which in this case put the spray nozzle in question out of operation and, if appropriate, trigger a corresponding warning or control signal. It must be ensured that it is no longer pushed towards the vehicle body and the spraying process must not be initiated.
  • the first requirement can be achieved by appropriate control measures by measuring the pressure on the nozzle and its altitude and comparing it with a predetermined value. When this value is exceeded, actuators are actuated which allow the spray nozzle to give way downwards.
  • the spray nozzle is assigned an overload clutch, which disengages the spray nozzle in the event of excessive vertical pressure.
  • the prevention of the spraying process can be controlled by an electrical switch which is actuated when the nozzle yields.
  • the device according to the invention has a stop which urges the notched spray nozzle into its original position when the carrier frame is moved back, so that this spray nozzle is functional again with the next body to be preserved.
  • Claim 6 includes a nozzle system that is particularly advantageously suitable for the device according to claim 1. After positioning, it allows the spray nozzles to be threaded even if there are large tolerance differences in the individual through openings of the cavities. Furthermore, this nozzle system keeps the spray nozzle protected from damage in the nozzle holder. It only emerges from it during the spraying process. Despite particularly good suitability for the device according to claim 1, the nozzle system according to claim 6 is not limited to this.
  • the nozzle head is kept encapsulated in the nozzle carrier during the rest position.
  • the solvent contained in the preservation liquid cannot evaporate or can evaporate only with difficulty.
  • the outlet openings of the spray nozzle do not become resinous.
  • a cleaning liquid can be supplied in the area of the encapsulation of the spray nozzle, which can wash away any resinous outlet openings. The device according to the invention is thus always ready for operation, disassembly and washing of the spray nozzles is not necessary.
  • the spray nozzle can be finely positioned, as already indicated, and can even be inserted into smaller openings.
  • the nozzle carrier has corresponding means on its section facing the cavity to be preserved.
  • These funds can consist of molded jaws, which are designed as an image of the outer contour of the cavity.
  • mandrels can be provided on the nozzle carrier which engage in a corresponding receptacle of the body in the vicinity of the cavity to be preserved. Such mandrels can be useful if only one-way positioning is possible via the mold jaws; a side member is an example.
  • mold jaws can also be used in combination with such mandrels for fine positioning.
  • the spray nozzle In order to obtain a standardization of the components, it is further advantageous to construct the spray nozzle from a hollow nozzle body and an interchangeable nozzle head placed thereon.
  • the holder must accommodate the nozzle head in a defined position so that the spray pattern of the replaced nozzle corresponds to the assigned cavity.
  • the vehicle body When preserving, the vehicle body is first brought into its correct position by the positioning device of the device according to the invention. Then the support frame moves up towards the vehicle floor.
  • the fine positioning means of the nozzle systems dock onto the outer contour of the cavities.
  • the nozzle carriers When the support frame moves upward further, the nozzle carriers are held back against spring force and the spray nozzles emerge from them with their nozzle heads and into the cavities.
  • the initial height of the nozzle heads, when the support frame is still in its initial position, is set so that when the stroke movement has ended, they are immersed in the respective cavity by the amount predetermined by the spray pattern.
  • the nozzle systems can be designed to partially or all dock at the same time. They are then arranged on the support frame in their height according to the contour of the vehicle floor.
  • the arrangement of the nozzle systems on the support frame with respect to their height and that of their spray nozzles depends on the respective application. There may be cases in which individual spray nozzles interfere with spraying at the same time.
  • a corresponding control is to be provided for the stroke movement, by means of which, if necessary, individual nozzles spray earlier, for example, and then disengage or start spraying during immersion, etc.
  • the spray nozzles are moved into the cavities by corresponding actuating devices.
  • the spray nozzles can be pressurized with compressed air.
  • the movement can take over a cylinder-piston unit arranged in the nozzle carrier.
  • cavities can also be preserved, in which the spray nozzle does not have to retract vertically, but at an angle. It is particularly advantageous if the two nozzle systems are combined with one another, in which case the spray nozzles that retract vertically are positioned via the second stroke of the support frame. The inclined spray nozzles of the second nozzle system are then retracted.
  • the nozzle head If very long cavities are to be preserved or complicated spray patterns are required, it is advantageous to provide the nozzle head with an extendable spray insert.
  • This spray insert is advantageously encapsulated in the nozzle head.
  • the spray insert can, for example, be designed telescopically for long cavities. With this type of spray nozzle, it is furthermore expedient to shape the nozzle head as a positioning mandrel. It can then align itself with the passage opening of the cavity.
  • the device according to the invention has a single support frame for all spray nozzles.
  • the contact pressure can increase excessively when docking. In this case, it is advantageous to subdivide the support frame and to carry out the preservation process in the resulting sections.
  • the carrier frame can also accommodate the nozzle set of a second.
  • the nozzles of the model that is not to be preserved are released or held down in the manner described above.
  • a support frame equipped in this way allows more flexible production control.
  • the device shown in Fig. 1 consists of a positioning device 1 and a support frame 2.
  • the positioning device 1 which is symbolically represented in the figure by two cylinder-piston unit, carries a body 3, the cavities of which are to be preserved.
  • the pistons of the positioning device 1 are on their ends to form mandrels which engage in corresponding openings in the body 3.
  • the support frame 2 can be moved in the direction of the double arrow 4 in the vertical direction up and down. It slides in guide rails 5. It can additionally or exclusively be guided in the positioning device 1. Furthermore, the guide rails 5 can be rigidly connected to the device 1.
  • Nozzle systems 6 are arranged on the support frame 2. 1 shows four such nozzle systems 6; they are intended to represent the entire set of nozzle systems which are required for the preservation of all cavities in the body 3 which are accessible from below.
  • the nozzle systems are arranged in their vertical positions so that their ends facing the vehicle body 3 lie approximately on a line which is denoted by 7 in FIG. 1 and shown in broken lines. This line runs approximately at the same distance from the bottom contour of the body 3.
  • the body 3 has at least one opening (not shown) for the passage of the spray nozzles for each cavity to be preserved.
  • the spray nozzles of the nozzle systems 6 are arranged on the support frame 2 such that they correspond to the hole pattern of these through openings.
  • the vehicle body 3 is placed on the positioning device 1 by a transport mechanism and, if necessary, is fixed by additional holding means, not shown. Then the support frame 2 moves up until the nozzle systems 6 dock on the bottom of the body. Now the spray nozzles are moved into the respective cavities either by a further stroke of the support frame 2 or by other drive means until they reach a predetermined position. The actual spraying process then begins. , The spray pattern of each nozzle is matched to the shape and dimensions of the cavity assigned to it. After the spraying process has ended, the carrier frame 2 moves with the spray nozzles down again. The body 3 is then transported further to the next work station by the transport system.
  • FIG. 2 shows a first exemplary embodiment of a nozzle system 6.
  • the nozzle system 6 consists of a nozzle carrier which is designated overall by 8 and essentially consists of two main parts 9 and 10.
  • the first or lower part 10 of the nozzle carrier 8 is fixed on the carrier frame 2 via an overload clutch 11 and a resilient intermediate layer 12 made of, for example, rubber-like material.
  • the second or upper main part 9 of the nozzle carrier 8 faces the cavity to be preserved, which is not shown in this FIG. 2. It is supported by a compression spring 13 on the lower part 10.
  • the spring 13 can also be a gas suspension.
  • molded parts 14 are firmly connected to the upper part 9 and depict the outer contour of the cavity to be preserved; in this case, for example, that of a body support.
  • a spray nozzle 15 is fastened in the lower part 10 of the nozzle carrier 8.
  • the spray nozzle 15 is composed of a tubular nozzle body 16 and an exchangeable nozzle head 17. At its free end, the nozzle head 17 has openings 18 for the outlet of the preservative. In the rest position, the nozzle head 17 is sunk in the nozzle holder 8.
  • the nozzle body 16 is connected to a line 19 for the inflow of the preservative.
  • the support frame 2 moves upwards according to the arrow 4, it takes the nozzle system 6 with it.
  • the shaped jaws 14 soon dock onto the vehicle floor and thus align the nozzle head 17 precisely with the passage opening in the body. If the frame carrier 2 now moves upward, the upper part 9 of the nozzle carrier 8 is retained. The nozzle head now emerges from the upper part 9 and into the cavity, not shown.
  • the overload clutch 11 responds.
  • the nozzle head 17 encountering resistance in this case is subjected to pressure.
  • This pressure causes a rod 11a of the overload clutch 11, which is firmly connected to the lower part 10 of the nozzle body 8, to be released.
  • the rod 11a is guided in a holding part 11b, which in turn is firmly connected to the carrier frame 2 via the elastic intermediate layer 12.
  • the nozzle system 6 slides down with the rod 11a, a stop 11c limiting the path.
  • the notched nozzle system is shown in broken lines in FIG. 2.
  • a stop 20 can also be seen here, which is identical to a corresponding stop 20 in FIG. 1.
  • the stop 20 acts on the notched nozzle system 6 when the support frame 2 moves downward.
  • the nozzle system 6 is thereby shifted upwards into its original position and is ready for operation again for the next upward stroke.
  • limit switches 21 can also be seen. They should represent all signaling devices and the control of the preservation process.
  • the piercing opening in the upper part 9 of the nozzle carrier 8 for the nozzle head 17 has a closure 22.
  • the closure 22 is only hinted at and is symbolic of the encapsulation of the nozzle head 17. It can be made of resilient material and, when the nozzle head 17 is recessed, seal it off to the outside. This largely prevents the solvent with which the preservative is added and keeps it liquid, evaporates and the exit openings 18 of the nozzle head 17 become resinous as a result.
  • the encapsulation of the nozzle head 17 could also be carried out in a different way. So could 19 sealing rings can be provided above and below the outlet openings 18 in the upper part. Furthermore, a room which is closed off in this way could additionally be supplied with a washing liquid which rinses the outlet openings 18 which may become resinous.
  • the nozzle system shown in FIG. 3 differs from that according to FIG. 2 in that the nozzle carrier, here designated 23, consists of a one-piece tube with attached mold jaws 14. After this nozzle system has been docked, the spray nozzle 24 is moved pneumatically or hydraulically upward with a piston-cylinder unit 25, a piston rod 26.
  • the piston-cylinder unit 25 is designed so that the spray nozzle 24 can be held in any position within its stroke.
  • the inflow line for the pressure medium is designated 25a. While the supply line for the preservative also bears the reference number 19 again.
  • FIG. 3 Another possibility of an “upper-load clutch” is indicated in FIG. 3.
  • the inflow line 25a has a symbolically indicated valve body 25b and a vent line 25c.
  • the pressure increase and the extended distance of the spray nozzle are measured (not shown in detail). If the pressure rises excessively when the spray nozzle is not fully extended - the spray nozzle encounters an obstacle - the valve body 25b opens and releases the vent line 25c so that the spray nozzle 24 can return to its lowered position.
  • the valve body 25b is shown half open. With 27 a plate is designated with which the nozzle system can be attached to the support frame.
  • FIG. 4 shows a nozzle system 6 in which a cylinder-piston unit is arranged in the nozzle carrier 28.
  • the supply line of this unit 29 can be seen at 30 and 31.
  • the unit 29 has a band 32 to which the spray nozzle 33 is fastened via a guide 34. By appropriate pressurization via the supply lines 30, 31, the band 32 pulls the spray nozzle 33 either out of the nozzle carrier 28 or into it.
  • FIG. 5 shows, on an enlarged scale, only a nozzle head 35 with a spray insert 36 which can be extended telescopically.
  • Each telescope section 38 has corresponding openings for the escape of the preservative. If the spray insert is withdrawn into its rest position, these outlet openings are again largely closed off from the outside and thus encapsulated.
  • the nozzle head 35 has a frustoconical shape at its end facing the cavity. It thus acts as a positioning mandrel when it docks onto the cavity 3 '.
  • the embodiment according to FIG. 6 differs from that according to FIG. 5 essentially only in the different design of the spray insert 40.
  • the spray insert 40 here has a T-shape which is traversed by flow channels. This spray insert 40 enables a complex spray pattern that is necessary in some cases to be achieved.
  • nozzle systems can of course be combined with one another.
  • different nozzle systems can be contained in each nozzle set.
