  • the invention relates to an electronically controlled Winch device according to the preamble of patent claim 1.
  • a winch device is for example with the The subject of EP 0 369 173 B1 has become known.
  • Known winch device has the disadvantage that the Tools for bending the spring diameter, for the Completion of the slope and for the wire feed over relatively long and with playful drive devices are driven.
  • Such drive devices are especially belts made by corresponding electronic regulated drive motors are driven.
  • Each drive motor acts on one via a toothed belt corresponding drive axle, which rotatably with Transmission links is connected, which consists essentially of There are cams that are associated with that Cam scanning rollers are connected, which Scanning tools in turn connected to the bending tools are.
  • the known device has the disadvantage that that many mechanical components must be used, which the Manufacturing costs of the machine increased greatly and also the Maintenance effort, the susceptibility to repairs and the Frequency of wear increased.
  • FR-A-2 238 546 also describes an electronically controlled one Winding device, with a pitch tool and a Bending pin driven by a Vervomotor translatory become.
  • the invention is therefore based on the object To further develop the winch device of the type mentioned at the outset, that the individual drive trains have improved turning and Flexural rigidity can be assigned.
  • An essential feature of the invention is that now due to the short and equipped with few transmission elements Drive trains an improved torsional and bending stiffness of the respective drive train is reached.
  • the invention electronically controlled servo motors can therefore be used their movement immediately with the interposition of little Transfer links directly to the bending tools and the Transfer drive rollers, which is now the first time a wire with reduced tolerances to a corresponding one Bend spring.
  • the Servomotors are electronically controlled and the movement of the Servomotors exactly according to the required spring shape can be adjusted.
  • the spring to be produced is first used described a mathematical model, which of the regulation is entered. According to this regulation, the Movements of the individual servomotors are controlled. It is now possible, based on the derivation from a mathematical model a changed feather shape relative generate quickly because you can rely on the production of waive different experimental springs. Before with the known machines had to test springs in large Number can be produced, then based on the received Spring form to adjust the drive chain so that the desired feather shape was achieved. This is with the present invention no longer necessary because starting out the different from a mathematical model Control commands for the various servo motors directly be programmed and therefore committee springs, which for the Further processing is unsuitable, to a large extent be avoided.
  • the servomotors are common among themselves Control connected so that, for example, the angle of rotation one of the servomotors is queried and then the Angle of rotation of the other servo motors or readjusted becomes.
  • the wire feed with a speed or rotation-controlled servomotor and this Servomotor via a gearbox on the synchronously driven Pull rollers act that are oppositely driven between themselves form a gap through which the wire is drawn in and is transported.
  • a stepped transmission is preferably used here, which is designed as a spur gear.
  • the spur gear described can also be an angular gear or a belt transmission can be used.
  • the bending tools each are only moved in translation, d. H. they are just in driven one level each, with a displacement drive for the respective bending tool also other turning and rigid drives as essential to the solution become.
  • the bending roll in one Sled is guided, which sled over a spindle is driven so that the bending roller is translational Assign shift actuator.
  • the swivel drive of the bending roller is therefore a pure one Translational drive of the bending roller realized.
  • Incline tool which is also direct and can be driven in translation.
  • Incline tool in turn in a sled that over a Spindle drive or another translatory drive is driven.
  • the incline tool it is also possible to use the incline tool to be designed as a swivel tool, a translatory and / or pivotal movement provided for the incline tool becomes.
  • the cutting tool (cutting tool) driven by an electronically controlled servo motor becomes.
  • This leads to short connection paths between the servo motor and the cutting tool to be able to make an exact cut.
  • toggle lever has the advantage that it is relative large cutting forces with low drive power of the Servomotors can be generated.
  • the wire no longer by a so-called Wire guide tube is fed to the bending tool, instead there is a free feeding of the wire without Passing the wire through an appropriate Guide tube.
  • a tube are now according to the invention in Direction of transport staggered wire guide rollers arranged, one of which is a wire guide roller above attaches to the wire and the other wire guide roller itself the bottom of the wire and the two wire guide rollers are arranged offset to one another in the transport direction.
  • a wire 1 is in the direction of arrow 2 passed through pull rollers 6,7 and from these in Feed direction driven.
  • the pull rollers are over one common gear 5 are driven synchronously and hereby acted upon by a drive axle 4, which of a rotation angle controlled servo motor 3 is driven.
  • the bending device 8 consists essentially of a Bending tool, which is designed as a bending roller 28 and from a pitch tool 30.
  • the bending roller 28 is controlled by a speed Servomotor 22 driven while driving the Incline tool 30 via a speed-controlled Servomotor 35 takes place.
  • the servo motor 22 drives one via a drive shaft 23 Cam 24, which is with its outer circumference on the outer circumference a roller 25 supports the free, pivotable part a lever 26 is arranged, which in the pivot axis 27th is pivotally mounted.
  • the bending roller 28 sits on the opposite arm consequently in the pivoting of the roller 25 in the Arrow directions 49, 50 (see FIG. 3) are displaceably driven is.
  • the displacement drive of the incline tool 30 is in similarly resolved.
  • the servo motor 35 overdrives its drive axis 36 a cam disk 34 (see FIG. 2) rotating, which cam disk 34 has a curved track 37 defines in which a role 33 translationally is guided.
  • the roller 33 sits according to Figure 2 rotatable but immovable on one in the Arrow directions 42, 43 slidable in the range of Straight guides 41 mounted plunger 32.
  • the plunger 32 is connected to the pitch tool 30, which has a contact edge 31 with which the Incline tool 30 on the wire section 29 to be bent creates.
  • Servo motor 9 is provided, on its drive axis 10 a gear 11 acts, the output-side axis of rotation 15 is rotatably coupled to a cam 12.
  • the outer circumference the cam 12 lies on the outer circumference of an associated one Roll 16 on which is rotatable in the pivotable part of a Knee lever 62 is arranged.
  • the toggle is here fixed to the housing in the pivot axis 17 and pivoted takes up the roller 16 in the region of its axis of rotation 18.
  • a pivot axis 19 is arranged in which the upper knife 13 is held, which in not is shown in more detail in a straight guide.
  • the upper knife 13 is arranged fixed to the housing Lower knife 14 opposite.
  • wire guide rollers 20,21 are rotatable, is also a correspondingly low Wear present, because with the previous ones Wire guide tube was a constant friction with one to accept the corresponding pollution.
  • FIG. 4 shows a further embodiment of the invention shown. It can be seen here that the movements of the individual tools 28,30 through purely translational Movements can be performed.
  • the bending roller 28 is in the region of a slide 44 rotatably mounted, which is received in a guide 45.
  • the carriage 44 is here, for example, with a spindle 46 connected, which is rotatably driven by a spindle nut 47 which in turn is driven by the servo motor 22. In this way, the carriage 44 is in the direction of the arrow 49.50 in the guide 45 moved translationally and it results also a practically backlash-free, low-loss and rigid translatory guidance of the bending roller 28.
  • a control according to the invention is shown schematically in FIG shown.
  • the axis control 58 sits at the input of the motor control 56, which initiates the control commands into the motor control 56.
  • the mathematical model thus becomes in the axis control 58 predefined to generate the desired spring and this Electrical control commands are then given to the individual axes fed.
  • the return of the individual commands and the Connection of the individual engine controls 56 to one another takes place via an optical fiber ring that commands all accepts and in the sense of a bus to the axis control 58 leads back.
  • the axis control is programmable with a Controller 59 coupled, which is controlled by a computer 60 can be.
  • the corresponding control commands can be via an operator terminal 61 can be entered.
  • Regulation 51 also contains other regulation mechanisms shown. It is stated that regulation 51 also can be used for that with the help of motors 54,54a, 54b knots can be attached in the spring and that a transport star is provided outside the winch part can be.
