Definitions

  • the invention relates to an arrangement for the continuous production of reinforced, tube-shaped structures having:
  • the invention relates further to a method for continuously making reinforced, tube-shaped structures.
  • a rolling-lobe flexible member blank is made of rubber layers and reinforcement layers which are tube-shaped and layered one atop the other.
  • the rolling-lobe resilient member blanks are made in that cut-out rubber plates and fabric strips are laid one atop the other and are further processed. This is relatively complex and subject to faults.
  • EP 0 285 726 B1 a method for applying a filament or cord layer at defined cord angles to a rubber layer is described with the rubber layer being extruded onto a mandrel.
  • the mandrel with the rubber layer is clamped into a lathe and rotated while a cord let-off ring surrounds the mandrel and is moved forward in the longitudinal direction of the mandrel with the cord let-off ring being fixed with respect to rotation.
  • a winding method for the continuous production of hoses is described in DE 1 180 513 wherein the rubber and reinforcement layers are wound on an endless row of mandrels in series one behind the other and driven in an advancing direction.
  • the hose is vulcanized on the mandrels.
  • the mandrel component pieces are pulled away and are releaseably hooked to the end of the mandrel component piece running into the winding machine.
  • the precision, which is required for air spring resilient members can disadvantageously not be ensured in the winding method.
  • the mandrels are thermally loaded during vulcanization and the danger is present that the mandrels can deform so that a uniform quality of the rolling-lobe resilient member blanks can no longer be ensured.
  • a method and an arrangement for manufacturing curved rubber hoses is described in DE 25 45 058 C3 wherein rubber and reinforcement layers are applied continuously on mandrels driven in a conveying direction with at least one extruder and one cord reinforcing machine.
  • the mandrels abut directly and seamlessly one against the other.
  • two mandrels are so displaced with respect to each other that a gap arises between their end faces wherein a cutting knife of the cutting apparatus can engage.
  • the filament or cord layers are stretched in the hose blank and are displaced in their positions.
  • the mandrels are flexible and are brought into a curved position together with the hose or tubular-shaped blank piece, which is disposed on the mandrel, and are vulcanized in a vulcanization facility.
  • the vulcanized curved hose is subsequently separated from the mandrel.
  • the mandrels are rigid; the mandrels are coupled one to the other so that, in each case, a peripheral cutting zone is provided by a material different from that of the mandrel; and, that the arrangement is so aligned that the vulcanization of the reinforced hose-shaped structure takes place only after strip off.
  • the dimensional accuracy of the mandrels is not affected by the thermal process of the vulcanization because the reinforced hose-shaped structures are stripped in advance of the vulcanization from the individual mandrels. In this way, a uniform manufacturing quality is ensured.
  • a separating means application device for providing separating means is provided on the periphery of the mandrels.
  • the separating means application device is arranged ahead of the first extrusion unit as seen in the conveying direction. With the applied separating means, it is ensured that the reinforced hose-shaped structures can be easily stripped from the individual mandrels after the manufacture.
  • a cutting device for cutting the stripped-off reinforced hose-shaped structures to defined vulcanization lengths.
  • the cutting device is mounted in the manufacturing process ahead of the vulcanization unit.
  • the stripped-off reinforced hose-shaped structures are cut once again in advance of the vulcanization.
  • the cutting device preferably has a cutting head drivable transversely to the longitudinal axis of the reinforced hose-shaped structures and drivable relative thereto.
  • the cutting device also has a fixing unit for clamping and fixing the reinforced hose-shaped structures in the cutting position.
  • the extrusion means preferably have a gear pump for supplying the extruded rubber or plastic to an extrusion head.
  • a measuring device is preferably provided for continuously measuring the advancing speed of the mandrels.
  • a control unit functions to control the quantity, which is supplied for the application of at least one rubber or plastic layer, and to control the rotational speed of the at least one bobbin creel unit in dependence upon the advancing speed in such a manner that a constant thickness of at least the first rubber or plastic layer and a defined angle of the at least one cord layer is formed.
  • a measuring device is provided for continuously measuring the thickness of the first rubber or plastic layer applied directly to the mandrels and a control unit is provided for controlling the rotational speed of the downstream bobbin creels in dependence upon the measured thickness of the first rubber or plastic layer.
  • the first extrusion unit thereby forms a control loop together with the downstream bobbin creel so that a constant cord angle is ensured in dependence upon the applied thickness of the rubber or plastic layer.
  • process variable measurement means are provided for measuring the process variables when applying the rubber or plastic layers and reinforcement layers.
  • a fault marking unit functions to apply markings to the reinforced hose-shaped structures when the measured process variables exceed or drop below a particular fault tolerance amount. In this way, it can be ensured that defective regions are separated out during the uninterrupted continuous manufacture.
  • the mandrels preferably have a length in the range of one to eight meters and especially preferable is the length of two to four meters.
  • Mandrel adapters are provided in order to be able to adapt the length of the mandrels flexibly to the production requirements. These mandrel adapters abut almost seamlessly against an assigned mandrel and are fixedly coupled thereto. In each case, the mandrel adapters have a coupling element for coupling the mandrel adapter to a further mandrel in such a manner that a cutting zone is provided from a material, which is different from the mandrel, between the mandrel adapter and the further mandrel.
  • the method of the invention for continuously manufacturing reinforced hose-shaped structures has the steps of:
  • the method of the invention is executed with rigid mandrels, which are coupled one to the other, with a peripherally-extending cutting zone from a material different to that of the mandrel so that, when separating reinforced hose-shaped structures into segments, it is no longer necessary to pull the mandrels apart. In this way, it is ensured that the position of the reinforcement layers is not changed by the separating operation.
  • the vulcanization of the reinforced hose-shaped structures after stripping off takes place so that the mandrels, which are used for making the reinforced hose-shaped structures, are not subjected to the thermal vulcanization operation.
  • FIG. 1 shows a schematic block diagram of a manufacturing arrangement for the continuous production of reinforced hose-shaped structures.
  • FIG. 1 shows an arrangement of the invention for the continuous manufacture of reinforced hose-shaped structures 1 which are formed of several rubber or plastic layers ( 2 a , 2 b ) one atop the other and reinforcement layers 3 .
  • the manufacturing arrangement has a first extrusion unit 4 a for applying a first rubber or plastic layer 2 a to the periphery of cylindrical, rigid mandrels 5 which are continuously coupled one to the other and driven by a conveying unit 6 in a conveying direction X.
  • the mandrels 5 are passed through the first extrusion unit 4 a so that a rubber or plastic hose is made.
  • the thickness of the first rubber layer 2 a is measured by a measuring unit 7 which is mounted behind the first extrusion unit 4 a viewed in the conveying direction X.
  • the first extrusion unit 4 a has a gear pump 8 between the extruder and an extrusion head in order to control the supplied rubber or plastic quantity precisely in dependence upon the thickness measured with the measuring device 7 .
  • a cord or filament layer is applied at a defined filament angle with a bobbin creel unit 9 which rotates about the mandrels 5 .
  • additional bobbin creel units 9 can be provided which can, for example, rotate in mutual opposition in order to apply at least one additional filament layer, which can be counter-running, as may be required.
  • At least one further extrusion unit 4 b is provided in order to apply a further rubber or plastic layer 2 b.
  • the advancing speed of the mandrels 5 is continuously measured by a measuring unit 10 .
  • the process variables are supplied to a control unit (open loop and closed loop) 11 and the extrusion units ( 4 a , 4 b ) and the at least one bobbin creel unit 9 are so open loop controlled and so closed loop controlled in dependence upon the speed of advancement and at least the thickness of the first rubber or plastic layer 2 a that a defined reinforcement layer 3 is ensured at fixed filament angles and a constant thickness of the rubber or plastic layers 2 is ensured.
  • first extrusion unit 4 a and the directly following bobbin creel unit 9 form a closed control loop because the filament angles of the filament layer, which is applied to the first rubber or plastic layer 2 a , is dependent upon the thickness of the first rubber or plastic layer 2 a .
  • the filament angles and the thickness of the first rubber or plastic layer define essential quality features of reinforced hose-shaped structures, especially for use in air springs.
  • Process variables (such as angles and quality of filament layers) for the reinforcement layers 3 as well as the quality and thicknesses of the rubber or plastic layers 2 are measured with suitable measuring means. Defective areas are identified with a fault marking unit 12 by applying markings to the reinforced hose-shaped structures 1 when the measured process variables exceed or drop below a particular fault tolerance amount.
  • a cutting device 13 is provided for cutting the reinforced hose-shaped structures 1 at the connecting locations of mutually adjoining mandrels 5 .
  • the cutting device 13 or the overall system has either suitable means for detecting the peripherally-extending cut zones S between mandrels 5 , which are one behind the other, or the cutting zones S are determined from the advancement speed.
  • the cutting device 13 can, for example, have a separating knife extending about the periphery of the reinforced hose-shaped structures 1 .
  • the mandrels 5 are decoupled from each other and the cut reinforced hose-shaped structures 1 are stripped off or pulled off the particular mandrel 5 with a strip-off device 14 .
  • a compressed air wave first migrates from the forward end of the reinforced hose-shaped structure 1 to the rear end and the mandrel 5 is pressed out by the pressurized air acting on the end face of the mandrel.
  • the mandrels 5 are preferably closed at the end faces.
  • the individual mandrels 5 are then returned by the conveying apparatus to the start of the manufacturing arrangement as sketched by the arrows. In this way, a continuous endless manufacturing process is ensured.
  • the stripped-off reinforced hose-shaped structures 1 are thereafter supplied to a cutting device 15 and cut to the defined vulcanization lengths. Viewed in the manufacturing direction, the cutting device 15 is ahead of a downstream vulcanization unit (not shown) for vulcanizing the cut sections of the reinforced hose-shaped structures.
  • the cutting device 15 has a cutting head 16 moveable transversely to the longitudinal axis.
  • a separating means application device 17 is provided for applying separating means to the periphery of the mandrels 5 .
  • the separating means application unit 17 viewed in the conveying direction X, is mounted ahead of the first extrusion unit 4 a. With the applied separating means, it is ensured that the reinforced hose-shaped structures 1 can be easily stripped off the individual mandrels 5 after manufacture.
