Definitions

  • the present invention relates to a feed device for feeding long material, in particular of strip, wire or profile material, along a feed direction, wherein the feed device comprises at least one clamping device with clamping jaws, which is adjustable between a clamping position in which they the long material between the jaws clamped holds, and a release position in which it releases the long material for movement relative to the jaws, and which is movable in the feed direction at least in the clamping position.
  • feed devices With such feed devices, long material is fed to downstream processing stations, which usually reshape the long material without cutting, in particular by bending, punching and the like.
  • a generic feed devices feeding devices are known in which a clamping device with jaws reciprocated by an eccentric and is driven forth. The clamping device of the known feed device clamps the long material, is then moved with the clamped long material the desired feed dimension in the feed direction, then solves the clamping engagement and is moved back against the feed direction to the starting position.
  • a disadvantage of these known feed devices inter alia, the complicated movement of the clamping device, which accelerates twice from standstill in each feed operation due to the change of direction and must be delayed twice to a stop. Due to these accelerations and delays, very high forces occur at the clamping device and at the drive connected to it. It should be noted in particular that the known feed devices are installed in production facilities for the production of mass-produced goods, so that these dynamic forces occur tens of times per minute.
  • feed devices in the form of so-called Rollenvorschübe known.
  • axially parallel rotatable rollers face each other, so that between their peripheral surfaces, a gap is formed, through which the long material is conveyed through.
  • the rollers lie on opposite sides of the long material and rotate in opposite directions.
  • One or both rollers are driven to impart the feed to the elongate material.
  • the rollers in the clocked feed operation although without reversal, to accelerate and delay again. Since the rollers are ideally in line contact with the long material with their peripheral surfaces, the contact force of the rollers to the strip material can be chosen only moderately to prevent excessive pressure and thus a change in shape of the long material by the feed rollers. However, this is the maximum transferable from the roles of the long material force and thus also the maximum achievable acceleration or deceleration limited, resulting in the end result in a limitation of the maximum achievable feed rate.
  • At least a clamping device is provided circumferentially along a closed path, wherein a feed path of the orbit runs in the feed direction and wherein the clamping device is at least partially in the clamping position during passage through the feed path.
  • any material is designated which in a spatial direction has a considerable, about at least two to three times, greater extent than in the other two spatial directions.
  • the term “long material” means a band, wire or profile material, which is advantageously unwound from a supply. This leads to advantageous longer service life between a long material change on the feed device.
  • An advantage of the clamping device according to the invention is that a dynamic load acting on the at least one clamping device can be reduced in its absolute value by selecting correspondingly large deflection radii from the change in direction of its movement speed during circulation compared with a direction-reversing clamping device from the prior art.
  • the centripetal acceleration resulting in a change in direction of velocity along a closed path is proportional to the square of the orbital velocity and is inversely proportional to the radius of curvature of the orbit.
  • the feed path may be formed by a straight line piece and the remainder of the closed loop path is curvedly connected to the straight feed path.
  • a greater radius of curvature of the web can be selected by accepting a larger track length.
  • the maximum feed speed achievable by the feed device can be increased, since no complete circulation of a clamping device has to be awaited between two feed operations. Rather, more clamping devices according to a preferred embodiment of the invention may be provided so that when a clamped engagement with the long material clamping device is disengaged by adjustment in the release position, a not yet in clamping engagement further clamping device by adjusting in the clamping position in clamping engagement comes with the long material. It will be understood by those skilled in the art that such engagement changes need not necessarily occur at the exact same time, although this is particularly preferred because it is then ensured that a clamping device is always in clamping engagement with the elongate material. Such an intervention change can also take place in a predetermined time window containing the intervention end, for example of up to 10% of the set cycle time with which the feed device is operated.
  • the total transferable from the feed device to the long material for its transport force can be increased advantageously in that the feed device comprises a plurality of clamping devices and a plurality of clamping devices during their movement in the feed direction is simultaneously in the clamping position.
  • the transferable from each of the clamping device simultaneously located in clamping position on the long material transferable clamping forces add up to a total force, so that the long material can be greatly accelerated and slowed down again without a position inaccuracy of the strip material is to be feared after deceleration.
  • the areal contact contact between the clamping jaw and the long material makes it possible to considerably reduce the local pressure load on the long material in the region of the clamping engagement, compared to the known roller feed devices. This means that, despite the transfer of high clamping forces in general, only comparatively moderate pressures act on the long material locally.
  • the at least one clamping device is connected for common movement with a shape-variable endless motion transmission part.
  • the shape-variable endless motion transmission part can be, for example, a chain, in particular a lamella chain, which allows transmission of very high forces in the direction of rotation.
  • a flexible toothed belt is preferred as a motion transmission part. If a plastic toothed belt is used, the resilience of the plastic provides for a damping of a possibly occurring starting and / or stopping shock.
  • the advantageous use of a toothed belt with metal core, in particular steel core thereby ensures that despite the temporary damping by elastic deformation of the toothed belt in the reached end position (rest position), the desired position is achieved with high accuracy.
  • a toothed belt with double-sided tooth formation is preferred, since then both a drive force transmission device on a first side of the toothed belt can be positively engaged with this, as well as the at least one clamping device on the first opposite second side of the toothed belt in the circumferential direction positively with this can be brought into engagement, so that neither the drive force transmission device nor the at least one clamping device has slip in the direction of rotation, which allows a very high positioning accuracy even at high feed rates and short cycle times.
  • each individual clamping jaw of each clamping device is provided with a force device which can be controlled by a controller in order to move the clamping jaw relative to a clamping device body carrying it along the clamping movement path.
  • a mechanical movement control of the at least one movable clamping jaw of a clamping device is preferred.
  • a cam track can be provided, which displaces a jaw movable along the clamping movement path towards and / or away from the respectively other clamping jaw.
  • Mechanical motion controls have the further advantage that they are fast and largely failsafe.
  • not only the necessary movement of the jaw can be effected by the cam track by the positive control thus taking place, but at the same time the required clamping force to be introduced by the cam track in the jaw.

  • the cam track can be designed in such a way that it moves the jaw in only one direction or in both directions, ie on the long material moves to and from this.
  • the secure clamping of the long material in the clamping device is of greater importance than lifting the jaw from the long material.
  • the latter does not necessarily have to be done, for example if the surface quality of the long material is not important.
  • the jaw must not be lifted from the long material, but it is sufficient to reduce the clamping force so far that the strip material can get out of engagement with the at least one clamping device.
  • the feed device is preferably designed such that the at least one along the Klemmschisbahn movable jaw is biased by a spring means in a Abhebewolf greater gap width and cooperates with the cam track for movement in an abutment position lesser gap width.

  • the jaw abutment surface is that surface of the jaw which comes to rest on one side thereof when clamping the long material.

  • a feed device it is advantageous for a feed device if it can transport long material of different thickness. An adjustment of the feed device to different thickness dimensions of long material can be done easily, if the feed device comprises a minimum gap width changing means which is adapted to change the occurring during normal feed operation during a pass through the feed distance between two opposing jaws smallest gap width. Due to the great advantage of the minimum gap width changing means for adapting generic feed devices, the applicant reserves the right to seek separate protection for this aspect as well.
  • the minimal gap width changing means preferably comprises a force device in force-transmitting relationship with at least one of the two opposing jaws such that the at least one jaw, upon application of force by the strength device, is in force opposite jaw to and away from this is displaced.

  • the power device may be a spring means, such as a helical compression spring, or a screw drive.

  • the cam can be displaced relative to the clamping device as a whole simply by the power device, so that the movable along the clamping movement path jaw occupies different jaw positions with different nip widths depending on the displacement position of the cam.
  • the cam track is acted upon in a predetermined displacement direction by the biasing force of a biasing spring element.

  • Fig. 4 the gear 56 and the gear 58 for adjusting the minimum gap between the jaws 20 and 22 in the feed path 34 are shown.
  • the cylindrical roller 62 is rotatably supported about its central axis 62a.
  • a toothing formed on its lateral surface meshes with the rack 52.
  • the rack 52 is connected for common movement with the piston rod 50 of the hydraulic cylinder 48 (see Fig. 2 at KP).
  • the cylindrical roller 62 with the cam track 32 coupled eccentric pins 63a and 63b.
  • the eccentrically provided with respect to the cylinder roller axis 62a pin 63a is coupled motion and force transmitting with the cam track 32 on the return path 82, while the provided at the opposite longitudinal end eccentric pin 63b is coupled to the cam track 32 on the side of the feed path movement and force transmitting.
  • the eccentric pins 63a and 63b of the cylindrical roller 62 are aligned coaxially with each other.
  • the remaining cylindrical rollers of the gears 56 and 58 are formed substantially identical to the cylinder roller 62.
  • the eccentric pins 63a and 63b are received in holes in the cam track 32.
  • FIG. 5 shows a section along the plane VV in FIG. 1 through the axis of rotation of the idler roller 72.
  • the same components as in the preceding figures 1-4 are with the same reference numerals, reference being made to the description of FIG. 5 to the description of the preceding figures.
  • jaws 20 and 22 are shown in detail, which are used in the clamping devices 16 of the feed device 10 according to Figures 1-5. In the following, only one clamping jaw 20 will be described, this description also being applicable to the clamping jaws 22, since these clamping jaws are identical.
  • the clamping jaws 20 have at their one longitudinal end 20a a rolling roller 28 which is designed to roll on the cam surface 30.
  • a commercially available rolling bearing can be used in an advantageous manner, wherein the outer surface 28a of the bearing outer ring is used as a rolling surface.
  • the Wälzrolle 28 is rotatably mounted about a pin 88 which is mounted in the mounted on the feed device state with the cam surface 30 parallel pin axis 88a.
  • a fork-like bearing formation 90 is provided at the longitudinal end 20a of the clamping jaw 20, in which the rolling roller 28 is rotatably received.
  • To the bearing formation 90 includes in the longitudinal direction of the jaw 20 to a shaft portion 92 which extends to the second longitudinal end 20 b of the jaw 20.
  • the shaft portion 92 is formed substantially cylindrical.
  • a frusto-conical clamping surface piece 94 is provided and secured with a screw on the shaft portion 92.
  • the clamping surface piece 94 is formed of cemented carbide or ceramic and provides the low-wear jaw abutment surface 94 a, which comes in abutment of the long material 12 in this system.
  • the remaining jaw 20 is preferably made of so-called.
  • Plastic mold steel which is also used for the production of plastic injection molds.
  • the shank portion 92 of the jaw 20 is provided with a compliance. This compliance is achieved by inserting slots in the shaft portion 92.
  • the slots 92a and 92b are all parallel to each other and orthogonal to the longitudinal axis 20c of the jaw 20, which is also the longitudinal axis of the shaft portion 92.
  • the slots 92a pass through the shaft section 92 in the region of the longitudinal axis 20c, d. H. in the region of the transverse center of the shaft portion 92a.
  • the slots 92b are cut in the radial direction toward the longitudinal axis 20c by the jacket of the shaft section 92, but do not reach the longitudinal axis 20c.
  • the slots 92a and 92b alternate at substantially equal intervals, the slots 92b always being provided in pairs opposite each other with respect to the longitudinal axis 20c.
  • the slots or indentations 92b from the outer shell of the shank portion 92 can be simply sawed in, while the passing recesses 92a can be made, for example, by wire eroding.
  • the shaft 92 is first pierced, in which case the wire is inserted into the bore for the subsequent wire EDM.
  • the shank portion 92 of the jaws 20 and 22 has an elasticity which provides sufficient compliance to compensate for differences in thickness of the strip material 12. These differences in thickness are to be compensated in particular when several adjacent clamping devices 16 are located simultaneously in the feed path 34 of the feed device 10 in the clamping position.
  • the clamping jaws 20 and 22 and their shank portion 92 have up to a force of 3000 N on a linear elastic behavior. With a diameter of 12 mm of the shaft portion 92 becomes at 3000 N a spring travel reached from about 0.15 mm. Experiments have shown that until this deformation, the shaft portion 92 can be considered as Hook's spring.
