Definitions

  • the invention relates to a profiling system for the longitudinal forming of a metal strip or output profile in a profile or tube by means of a plurality of in-line forming stations, in each of which a group of Rollumformtechnikmaschineen is summarized and which are followed by the metal strip or output profile successively, according to the preamble of the claim 1.
  • the metal strip or output profile passes through the individual forming stations in succession and is there each subjected to a forming step until it finally has received its (provisional) final form.
  • roll forming tool is used in the context of the present invention as a generic term for the forming rollers in a forming station, which may be formed as a lower roll, upper roll, side roll, intermediate roll or other role and can serve for forming or rolling of the workpiece.
  • Profiling systems of the present type are continuously operating systems that produce a longitudinally shaped profile (or tube) from strip material that is transported virtually endlessly through the profiling line. Since the profiles or pipes are therefore produced in a length corresponding to the length of the metal strip used as the starting material, finished or further processable profile pieces must be cut to length, which makes a corresponding cutting machine required.
  • the profiling plant usually also includes a profiling machine, besides the actual profiling machine formed from the forming stations Welding device in which the continuously running profile is welded longitudinally.
  • non-continuous processing machines such as embossing and flanging, integrated in the profiling. If these are to be arranged in front of the separating device in order, for example, to introduce punches into an already partially formed profile, before it is further longitudinally formed in further forming stations, the profiling system must brake the transport of the profile at intervals to a standstill, in order then to restart. During the standstill of the profile then the punching operation and the like can be performed. Only when a flat metal band is to be provided with punches before the first forming step, a deceleration of the profile transport can be avoided by a belt loop. As soon as a first, longitudinal bend has been introduced into the metal strip, this measure is eliminated.
  • the present invention is therefore based on the object to propose a profiling, can be integrated with less effort than before processing steps with discontinuously operating devices.
  • An inventively configured profiling with at least a plurality of fixed on a machine base forming stations therefore has on the machine base on linear guides, on which sit driven, in and against the direction of movement of the metal strip or profile movable carriage.
  • These carriages are used to accommodate acting on the profile tools, such as for cutting, punching, embossing and the like, as well as manipulators, welding equipment or other devices that work on the profile.
  • the movable carriages can be arranged before or between the forming stations and before or after the separating device, wherein the separating device itself can also be mounted on such a carriage. Processing steps after the separating device, which are carried out with tools on a carriage according to the invention, can be, for example, the setting of miter cuts or the introduction of punches or the like in the finished profile.
  • the linear guides preferably extend substantially along the entire machine base, but this is not necessary in the context of the present invention. It may, for example, be provided to provide linear guides with movable carriages according to the invention only in the area of the separating device. It is also possible, for example, to provide only a movable carriage with, for example, between two functional groups, each with a plurality of forming stations with an intermediate punching machine.
  • the invention is implemented so that a continuous machine base with continuous linear guides is present, so that the profiling can be modular on the machine base.
  • the linear guides on the machine base holding devices may be provided which are used directly for attaching functional groups with multiple forming stations or for the forming stations.
  • For the drive of the individual carriages can be provided that along the linear guides on or next to the machine base racks are mounted.
  • the cars can then run along driven racks along these racks.
  • the drive of the car can also be done by means of linear motors or otherwise. If the carriages are driven by linear motors, the primary part of the linear motor on the carriage and the secondary part on the linear guides along which the carriage runs expediently can be found.
  • each car is provided with a drag chain for supply lines, such as power lines, pneumatic lines and the like, so that it can move independently along the linear guides or on the machine base.
  • supply lines such as power lines, pneumatic lines and the like
  • the profiling system according to the invention need not be completely modular in order to develop particular advantages over the prior art. For example, it is sufficient to provide at least one carriage, which can be moved together with the separating device, with a manipulator which is equipped with gripping tools, following a running separating device. This engages the profile or tube to be separated before or during the separating cut, so that the severed profile or tube remains in a defined position and orientation after the separating cut.
  • the manipulator can then pass the severed profile or tube defined to a device for transporting away or further processing of the separated profiles or tubes, wherein it preferably sits on a carriage which can be accelerated to a speed which is above the normal profile speed; As a result, he can carry out an accelerated transport movement after the separation cut and separate the separated profile or tube for a better transfer of the following profile strand longitudinally.
  • This implementation of the inventive idea eliminates the previous disadvantage of all profiling systems according to the prior art, in which the separated by a follower cutting machine profile or tube on a transport device, a magazine or a tub falls, so that in particular the orientation, ie the angular position of the Profile or pipe around its longitudinal axis, left to chance.
  • the orientation of profiles in particular is important not only if they are to be further processed, but for example, even if they are packaged for shipping. Accordingly, a transfer of profiles defined in particular in their orientation had hitherto had to be done manually. Automated gripping of the profiles still possible during the separation process with the present invention enables the profiles to have a defined, known position and orientation when gripped. A defined in position and orientation transfer is then only a per se known control-technical question.
  • a running on a carriage according to the invention manipulator for the transfer of separate profiles, or preferably two such cars with manipulators is, as already mentioned, preferably able to accelerate the Profilbewegurig after separation of the profile to the separated profile of the subsequent profile strand separate before it is passed.
  • the transfer itself may then preferably take place relative to the direction of movement to the right and to the left, and this preferably in different positions relative to the profile movement.
  • profiles of different lengths can be sorted passed or, for example, low-quality profiles are discharged.
  • a plurality of separating devices may also be present, which preferably cooperate with one or more downstream manipulators.
  • This can significantly increase the productivity of the entire system, especially if only short pieces of the virtually endless profile are to be cut to length.
  • two profile pieces can be separated from the profile strand at the same time per operation while the production continues in undiminished speed.
  • the preferably present manipulators ensure that, in particular, located between two separation devices, separated profile pieces are removed in an orderly form from the range of motion of the separation devices.
  • FIG. 1 schematically an embodiment of an inventively designed profiling is shown in a perspective view.
  • This Profilierstrom is completely modular, for which in particular a continuous machine base 1 is present.
  • This consists essentially of one in its basic form U-shaped metal profile 2 with lateral projections 3.
  • the lateral projections 3 form linear guides 4 for along this linear guides 4 movable carriage 5.
  • Each of these cars 5 has its own drive device 6, the present case of a
  • a rack 7 is arranged parallel to the linear guides 4, in which the gears of the drive devices 6 of the movable carriage 5 engage.
  • each carriage 5 also has a drag chain 8 for (not shown) supply lines, in particular power lines for the drive device 6 and a signal line for the required control of the car. 5
  • each quick-change plate 9 carries four stands 10 for supporting roll forming tools (not shown), so that each one Frame 10 forms a forming station for the longitudinal forming of a metal strip or profile.
  • This metal band or profile is in FIG. 1 not shown; it is above the machine base 1, parallel to this, passed through the forming stations 10 and formed there step by step.
  • two functional groups 11 are thus set with several forming stations 10 each on a quick-change plate 9 on the machine base 1, and indeed spaced from each other. Between the two functional groups 11, as well as before and after a self-contained movable carriage 5 is arranged on the processing machines, in particular machines for pre- and intermediate punches, can be attached. These processing machines run during the processing step with the continuously transported through the functional groups 11 profile and thus can perform the processing at a relative speed "zero".
  • FIG. 1 The structure shown is merely exemplary; the number and sequence of the carriages 5 and the forming station functional groups 11 is completely free.
  • functions such as stamping, embossing, flanging, welding as well as the actual profiling and the separation can be arranged at each point of the profiling system.
  • This modular design makes it possible to realize any manufacturing strategies on a plant. Discontinuous processing steps, such as in particular punching, can be done while running, which increases the partial performance of the profiling.
  • discontinuous processing steps, such as stamping processes may be combined with other processes that require a continuous process, such as welding, foaming, scraping, and the like.
  • FIG. 1 shows Profilierstrom is finally provided with a separator 12 for separating the finished reshaped profiles, which in turn is mounted on a movable carriage 5 and operates in the follower operation. Downstream of the separating device 12, two further carriages 5 each having a manipulator 13 can be seen.
  • FIG. 2 This section of the present exemplary embodiment of a profiling system designed according to the invention is shown more clearly in FIG. 2:
  • the in FIG. 2 shown end portion of profiling from FIG. 1 includes the separating device 12 and the two manipulators 13, which are all mounted on a self-sufficiently movable carriage 5.
  • the two manipulators each actuate a gripper 14 for gripping a profile 15 before or during the separation in the separating device 12.
  • the carriages 5 of the two manipulators 13 accelerate in order to separate the profile 15 from the separating device 12 and the profile strip following this.
  • the manipulators 13 can pivot the grippers 14 counterclockwise so that the profile 15 is output to the left relative to the direction of movement. Due to the fact that the grippers 14 have already grasped the profile 15 during the separation process, the output of the profile 15 can take place with a known, defined position and orientation thereof.
  • further processing devices for example a device for introducing a miter cut into the profile 15, can be activated on further carriages (not shown) and already execute a miter cut during running.
  • the in FIG. 2 5 possibly also mechanically coupled run. As a result, only the flexibility would be limited with respect to different lengths of the profiles 15.
  • FIG. 2 illustrated end portion of a profiling can also be attached to a conventional, otherwise not inventively designed profiling and they are accordingly retrofitted according to the invention.
