Definitions
- the invention relates to a method and a device for the extrusion of curved extrusion profiles, the extrusion profile being formed in a die upstream of a counter beam of an extrusion system and then curved or bent by the action of external forces and separated in partial lengths in the press flow by means of a separating robot connected to a higher-level control system , supported and delivered to a shelf using a handling robot.
- extruded profiles which are continuously curved to one side with a predetermined radius or alternately curved in both directions, are divided into desired partial lengths, for example by sawing or flame cutting, and then transported away.
- desired partial lengths for example by sawing or flame cutting
- DE 101 41 328 A1 known a method and an apparatus of the type mentioned. It is provided there that a table which is arranged in the press outlet and supports the pressed strand, can be raised and lowered, is divided into functional fields, of which the rear functional field which adjoins the front functional field near the machine can be temporarily pivoted into a position inclined to the foundation.
- the front functional field always remains in its position, mainly takes over the support of the profile and, because it remains stationary, is also available for the subsequent extruded profiles, while the rear functional field, which can be swung down, ensures that the separated profile lengths are removed.
- the rear functional field is lowered so that this partial length can slide down from the support pad. There it can be gripped by a handling robot and transferred to a roller table. Until the rear functional field is swung up into its supporting position, the subsequent extruded profile is supported solely by the front functional field. In this way it is achieved that the strand profile partial lengths can be separated on the one hand, so that there is sufficient free space for the continuously following strand, and on the other hand there is a support surface for each subsequent strand either immediately or unchanged.
- surface damage to the extruded profile cannot be ruled out due to relative movements between the support surface and the deposited extruded profile, which is further enhanced by the heat of deformation.
- the invention is therefore based on the object of providing a method and a device of the generic type with improved operating properties.
- this object is achieved in that the handling robot is coupled to the separating robot via the control and how the latter is moved to a starting position in front of the extrusion press, in which it assumes a waiting position downstream of the separating robot, then synchronously with the start of the separating process and thereby taking over the extruded extruded profile and moving its pre-calculated extrusion path with the separating robot into the separating end position, from which the separating robot moves back to its starting position for renewed synchronization with the extruded extruded profile, while the handling robot transports the separated partial length to the storage area there filed and then returned to its waiting position.
- One embodiment of the invention provides that support means introduced into the extrusion path of the extruded profile temporarily support the extruded profile. This is when the handling robot covers its path to the storage area and then to its starting position for the waiting position.
- the stored partial lengths are cooled on their transport route for storage. This is done on the shelf and makes it possible to cool the extruded profile lengths down to a desired temperature before further handling or before the storage process.
- the object on which the invention is based is achieved in terms of the device according to the invention in that the separating robot is followed by a handling robot which covers the working area from at least the separating end position to a storage device and which has a carrying means that supports a separated extruded profile part length.
- the extruded profile is coupled to the cutting robot in a motion-synchronized manner and, after the cut, preferably by means of a saw blade of the cutting robot, is immediately taken over by the support means and transported, which is also synchronized with the movement of the extruded profile.
- the suspension element can advantageously be designed as a transport fork with several tines. This enables a variable, easily changeable wing that can be adapted to the respective profile or its curvature. This means that profiles that are curved into the third dimension can be transported without damage. This is supported by the fact that the handling robot is coupled to the separating robot via the control system and tracks the pre-calculated movements or squeeze paths of the profile in the same way as the saw robot, without any relative movements to the extruded profile.
- a temperature-resistant layer e.g. Kevlar, provided, supports the gentle transport or removal.
- the storage device consists of a plurality of endless belts arranged parallel to one another and spaced apart from one another at a distance. These enable a gentle transfer and gentle transport of the unchanged hot, separated extruded profile partial lengths with a resting rest on the belts.
- the storage device is followed by a cooling conveyor line, preferably also consisting of a plurality of endless belts arranged parallel to one another at a spacing.
- a cooling conveyor line preferably also consisting of a plurality of endless belts arranged parallel to one another at a spacing.
- a discharge table or the like is also possible, the cooling conveyor section or the discharge table being adapted to the respective requirements and also variable in terms of geometry.
- the geometry of the cooling area is not dependent on the process sequence in the area of the separating and handling robot.
- the storage device and the cooling conveyor section are of modular construction.
- This area can thus be easily extended in length and width.
- This can e.g. a more cost-effective outlet variant for certain profiles can be converted at any time into an extended variant for a broader range of profiles.
- the cooling conveyor line which could also be designed as a cooling tunnel, is advantageously assigned coolant loading elements.
- a tilting device for erecting the extruded profile partial lengths is arranged at the end of the cooling conveyor section, the extruded profile partial lengths can already be erected in their stack position for the downstream storage in the automatic sequence.
- the automated process chain for separating, cooling and storing separated, curved extruded profile partial lengths can be further favored by the fact that a stacking robot and a stacking storage device are connected downstream of the cooling conveyor line.
- the stacking robot has a gripper arm with an image recognition means.
- the image recognition means allows the gripper arm or another suitable gripping system to be brought into a position adapted to the curvature of the part length of the extruded profile before the takeover.
- the entire working area, in particular in front of the counter beam of the extrusion press, remains free and thus freely accessible and usable.
- Figure 1 is a plan view of an extrusion system for producing curved extrusion profiles with robots arranged in the outlet area;
- FIG 2 as a detail of the outlet area of the extrusion system according to Figure 1 in plan view a storage device with this downstream cooling conveyor and extruded profile storage device;
- FIG. 4 shows a representation as in FIG. 3, here showing a subsequent position of the robots
- Figure 5 is an illustration as in Figures 3 and 4, showing yet another position of the robot.
- a block 2 to be pressed is fed by means of a block loading device 3 up to a shaping die or a tool 4 to an extrusion press 5, of which essentially only its counter beam 6 and a guide tool 7 arranged on its outlet side are shown.
- the guide tool 7 is followed in the press flow or in the pressing direction by a separating robot 10, which is connected via a control line 11 to a higher-level control unit 12 and, in the exemplary embodiment, is designed as a sawing robot for dividing the extruded extruded profile 9 into curved extruded profile lengths 9a.
- the cutting robot 10 is coupled via the control unit or controller 12 to the entered, pre-calculated movements of the extruded extruded profile 9, thus travels with the extruded profile 9 in the press flow until the separating cut begins and ends in the separating end position 13.
- a handling robot 14 moved there into its waiting position finally takes over the severed extruded profile partial length 9a and transports it for storage onto a storage device 15.
- the handling robot 14 is connected to the higher-level controller 12 via a control line 16 and consequently also moves synchronously with the extruded extruded profile 9 or the extruded profile partial length 9a.
- the handling robot 14 which covers the entire working area from the storage device 15 to at least the separating end position 13 is provided with a carrying means 17 which is designed as a transport fork 18 with three prongs 19 in the exemplary embodiment.
- These tines which may have a temperature-resistant layer on their surfaces, support the extruded profile part length 9a from below without relative movement, carry the extruded profile part length 9a in a stationary position to the storage device 15 and deliver it there.
- the depositing device 15 here consists of a plurality of endlessly circulating belts 20 which are arranged in parallel at a distance from one another and which open into a cooling conveyor line 22 which also has a plurality of belts 21 which are arranged at a spacing in parallel and - as shown in FIG. 2 - the extruded profile partial lengths 9a transfer to tapes 21.
- the cooling conveyor section 22 has a plurality of successively provided coolant loading elements 23.
- a tilting device 24 is arranged, which erects the extruded profile partial lengths 9a before they are placed in a storage rack 25.
- a stacking robot 26 is provided which has a gripper arm 28 equipped with an image recognition means 27.
- FIGS. 3 to 5 show the process flow in different operating sequences.
- the separating robot 10 When an extruded profile 9 begins to be pressed out, the separating robot 10 is in the starting position, as is the handling robot 14, which assumes a waiting position reaching the hatched work area 33 of the separating robot 10.
- a the work area 33 of the Separating robot 10 adjoining support means 29 in the form of a plurality of rollers 32 arranged in a frame 30 is in a lowered position which does not obstruct the path of the handling robot 14 with its carrying means 17.
- the cutting robot 10 moves from the control or control unit 12 (cf. in the separation end position 13, as shown in Figure 4.
- the extruded extruded profile 9 or the separated extruded profile partial length 9a has been placed on the support means 17 of the handling robot 14 which is in the waiting position.
- the handling robot 14 with its suspension element 17 has also been moved synchronously. From the operating position according to FIG. 4, the handling robot 14 with its suspension element 17 moves away from the work area 33 and, as shown in FIG. 5, places the extruded profile partial length 9a on the storage device 15. According to FIG. 5, the separating robot 10 already returns to its starting position in order to be synchronized with the sequence of movements of the continuously cut extruded profile 9.
- the support means 29 is raised as shown in FIG. 5 and during this time takes over the support of the extruded profile 9 pressed out beyond the working area 33. It is lowered when the manipulating robot 14 has moved back and then the support and takeover of the extruded profile 9 or the separated extruded profile part length 9a takes over again.
- This interplay with the automated process chain for separating, cooling and storing extruded profiles 9 or extruded profile partial lengths 9a is repeated until the operating weight of the block 2 to be pressed is used up and starts again each time a new block is loaded and pressed out.
