Definitions

  • the invention relates to a corrugator for producing pipes, in particular corrugated pipes.
  • Corrugators are used, for example, to manufacture corrugated pipes.
  • a plastic material is introduced into the corrugator and, by means of overpressure and / or underpressure, is brought to bear on molding surfaces which are formed on the mold jaws of the corrugator in order to form the corrugated pipe.
  • the corrugator usually comprises a plurality of mold jaws which have the molding surfaces.
  • the mold jaws typically move in a rotating manner on the corrugator, so that depending on the rotational speed, number and size of the mold jaws, one and the same mold jaw repeatedly passes a defined position on the corrugator after a predetermined time.
  • the corrugator can be equipped with molding jaws in such a way that all molding surfaces of the molding jaws are identical to one another. In this way, an endless corrugated pipe with a uniform diameter can be produced. In a subsequent processing step, this endless corrugated pipe can then be cut to the desired lengths.
  • corrugated pipes that have a variable diameter over their length, for example an area with an enlarged diameter compared to the rest of the corrugated pipe
  • the corrugator can be equipped with molding jaws, which enable the production of corrugated pipe sections with a small diameter from Allow corrugated pipe sections with increasing diameter, a production of corrugated pipe sections with a large diameter and a production of corrugated pipe sections with decreasing diameter.
  • the corrugator works, only an endless corrugated tube can be produced in which the enlarged diameter occurs in a constant periodic sequence. If, for example, corrugated pipes are desired which have exactly one section with an enlarged diameter, then these can only be produced in a single length without producing large waste of material.
  • the equipping of the corrugator for each corrugated pipe has to be reconfigured in a complex manner.
  • the corrugator is usually equipped by hand or using complex additional units.
  • the process has to be interrupted, in particular a corrugator has to be brought to a standstill.
  • corrugator Because of this high expenditure of time and money to equip a corrugator, small series or even one-off production of specific corrugated pipes are often not feasible. It is therefore the object of the present invention to provide a corrugator which makes it possible to flexibly adapt the design of a corrugated pipe to be produced during the production process and thereby reduce the set-up costs of the corrugator.
  • a corrugator for the production of tubes in particular corrugated tubes, comprising at least two sequences of rotating mold jaws, each of which have at least one shaping surface, wherein in a predetermined area of the corrugator two mold jaws abut against one another in such a way that their molding surfaces form a mold for forming a tube, at least one changing device which is set up to hold a mold jaw of the corresponding sequence of mold jaws against one on one to exchange mold jaws assigned to the waiting position assigned to the changing device, wherein the changing device is further configured to change the mold jaw while the sequence of mold jaws is being advanced on the corrugator, and wherein the corrugator further comprises a provision device which is configured to produce a predetermined mold jaw from a plurality of mold jaws, which is arranged outside the series of mold jaws running around the corrugator, to be taken and made available to the waiting position of the changing device and / or a mold jaw present at the waiting position z u remove and feed these mold jaws to the pluralit
  • the provision device can remove a corresponding molding jaw from a storage device and make it available at the waiting position. If a mold then passes through the rotating sequence of mold jaws, which can be taken from the sequence of mold jaws on the basis of a previous determination, the changing device can remove this mold jaw from the sequence of mold jaws and at the same time the mold jaws provided at the waiting position in the Insert sequence of mold jaws.
  • the removed mold jaw can be removed from this corresponding waiting position by the provision device and are stored, for example, in the storage device of the plurality of mold jaws which are not part of the sequence of mold jaws rotating around the corrugator.
  • the changing device is set up to apply a first predetermined force, for example a predefined pressure, against the sequence of rotating mold jaws as soon as the mold jaw to be removed enters the changing device . If the mold jaw to be removed has then completely entered the changing device, the changing device can be set up to carry out the changing process with a second predetermined force, for example a pressure.
  • the second predetermined force can be greater than the first predetermined force.
  • the changing device can be designed in such a way that a receiving width of the changing device, i.e. a width of the section of the changing device which receives a mold jaw to be removed, removes it from the sequence of rotating mold jaws and removes a mold jaw provided at the waiting position into the sequence of inserts circumferential mold jaws, essentially corresponds to the width of a single mold jaw.
  • the “width” of an individual mold jaw or the changing device is a dimension which is measured along a direction of advancement of the sequence of mold jaws on the corrugator.
  • a play compensation unit can also be provided on the corrugator, which is set up in the event that the mold jaw to be removed has a greater width than the mold jaw to be inserted to close a gap between adjacent mold blocks, and in the event that the mold jaw to be removed has a smaller width than the mold jaw to be inserted, to allow the two mold jaws adjacent to the mold jaw to be removed to be pushed apart in order to be able to insert the wider mold jaw between these two adjacent mold jaws.
  • the play compensation unit can electromechanically detect and compensate for play between adjacent mold jaws after the changing process.
  • Corrugators can for this purpose consist of several modules arranged next to one another, there being start and / or end modules which contain a curved area of the orbit and / or intermediate modules which form a straight area of the corrugator.
  • the start and / or end modules can be moved towards or away from the intermediate modules.
  • the end module which is also referred to as the “outlet module”
  • the start and / or end modules can advantageously run in a guide (for example a T-slot or a dovetail guide) introduced into the base plate of the corrugator.
  • the local change of the module can take place via at least one motor-driven spindle.
  • the electrical signal for adjustment for this can come from a computer unit which, based on a previously measured play between the mold jaws, can determine a corresponding angular rotation of the spindle and thus a shift of the start and / or end module.
  • the game can be recorded using a measuring device, for example an optical unit, which comprises a light-emitting and a light-receiving unit and / or a camera, which is set up to to detect a distance between two mold jaws.
  • the measuring device can preferably be arranged in an inlet area of mold jaws in the corrugator or in front of the drive unit, since a corresponding play can reach a maximum size shortly before this drive unit. This is because the drive unit for driving the mold jaws in the corrugator can push them in their direction of rotation so that the mold jaws can rest against one another in the direction of rotation after the drive unit. In order to detect the mold jaws, markings in particular can be attached to the mold jaws.
  • detection using RFID or QR code can also be carried out.
  • a sequence of successive molding jaw types can be recorded at the same time and compared, for example, with a predetermined sequence of molding jaw types.
  • a deviation of the detected and the predetermined sequence of mold jaws can be output as an error signal, for example.
  • the mold jaws can run in a largely closed channel at least along a section of a “return”, i.e. a section of the circulation path of a respective sequence of mold jaws that does not belong to the predetermined area of the corrugator in which the tube is formed.
  • the largely closed channel can, however, have openings through which an exchange of air present in the channel with ambient air and / or a removal of foreign bodies present in the channel is made possible.
  • the largely closed channel can have further interruptions, on the one hand to enable the mold jaws to be changed by the changing device and, on the other hand, to allow the provision device to remove and provide mold jaws from the waiting position.
  • There the further interruptions can be permanently open or can be opened during operation and / or are essentially closed by a section of the changing device.
  • the majority of the mold jaws arranged outside the series of mold jaws surrounding the corrugator can be arranged in an area which, in particular, is completely outside a section of the corrugator which is defined by the series of peripheral mold jaws and / or outside a Section of the corrugator, which is arranged in a direction perpendicular to a plane of rotation of a sequence of mold jaws above and / or below the section defined by the sequence of circumferential mold jaws.
