Definitions

  • the invention relates to a device for feeding and feeding tape material into an eccentric press, with the tape advancing, intermittently rotatably drivable rollers, which are operatively connected via a drive train to the drive for the eccentric shaft of the press, with a cam mechanism for intermittent rotary movement in the drive train the rollers depending on the angle of rotation of the eccentric shaft is provided.
  • Such a device is known, for example, from Catalog No. 510 "Press Feeds” from Ferguson from 1973.
  • the belt material is fed from a conveyor gap formed by opposing rollers in the case of roller belt feeders.
  • the rollers are driven by the eccentric shaft drive, which means that the feed movement is synchronized with the movement of the eccentric shaft.
  • the drive train for driving the rollers generally comprises a cam mechanism with which the uniform rotary movement of the eccentric shaft is converted into an intermittent rotary movement of the rollers, so that the rollers, and thus also the strip material, are not moved at least during the actual punching process, while the strip material is being fed when the press tools are disengaged.
  • a drive train for the rolls feeding the strip material has a transmission gear, in which gear sets can be exchanged in order to be able to vary the feed length of the strip material.
  • This exchange of gear sets is naturally complex and requires not only the corresponding long downtimes of the press but also the storage of corresponding gear sets.
  • the range of variation of the tape feed length is limited, so that it is not always possible to adapt the tape feed length to the tool used in each case and it is therefore often necessary to accept a material waste which is in itself avoidable.
  • roller belt feed is known from DE-A-2507701, in which the feed length can be adjusted with the aid of an actuator.
  • the epicyclic gear is designed as a planetary gear.
  • the superposition of the rotary movement can, for. B. done in that the ring gear, the planet carrier or the sun gear are driven by the motor, while the other two parts of the planetary gear form the input and output of the drive train.
  • the planetary gear is particularly preferably designed as a bevel gear planetary gear, the planet carrier being designed as a rotatable gear housing that supports the rotating bevel gears, on the outside of which a toothed ring meshing with a pinion of the motor is provided for rotating the gear housing, with the axis of rotation of the gear housing with the drive train connected input and output shafts are rotatably supported, which carry gears that mesh with the or the rotating bevel gears.
  • Such a transmission which is similar to the differential of a driven vehicle rear axle, only requires a very small amount of space and is therefore also suitable for small belt feeds.
  • the required control of the motor can be carried out particularly easily if the motor is designed as a three-phase servo motor. Such a control is preferably designed so that it controls the speed of the motor as a function of the angle of rotation of the eccentric shaft.
  • a cam mechanism is provided in the drive train for the intermittent rotational movement of the rollers depending on the angle of rotation of the eccentric shaft.
  • an eccentric press 1 is schematically shown with an up and down movable carriage 2 and a lower, fixed press table 3 in an overview.
  • the carriage 2 and the press table 3 carry unspecified tool halves, between which a material strip 4 is pushed intermittently when the tool halves are disengaged.
  • the material strip 4 is at rest.
  • the feed of this material strip 4 is effected by a feed device, generally designated 5 in FIG. 1.
  • the feed device 5 is driven via a belt drive 6 by the eccentric shaft 7, which at the same time also causes the lifting movement of the carriage 2 in a known manner.
  • the feed device 5 is thus driven via the same drive via which the eccentric shaft 7 is driven.
  • the feed device 5 is thus synchronized with the movement of the carriage 2.
  • Fig. 2 the actual feed device 5 is now shown in more detail. It can be seen that the belt drive 6 rotatably drives a cam roller 8, in which a rotary star 9 engages (cf. FIG. 3).
  • a transmission gear 10 is arranged on the shaft of the rotary star 9, the transmission output shaft of which is in turn connected to a transmission input shaft 11 of a bevel gear planetary gear 12.
  • the transmission output shaft 13 is connected to a feed roller 14 which, together with another roller 15, forms a conveying gap in which the material strip 4 is located and through which the material strip 4 is fed to the eccentric press 1.
  • the transmission input shaft 11 and the transmission output shaft 13 of the bevel gear planetary gear 12 are arranged opposite one another coaxially and each carry a bevel gear 16 and 17, respectively.
  • a gear housing 18 is rotatably arranged on the two shafts 11 and 13, which surrounds the two bevel gears 16 and 17.
  • a revolving bevel gear 19 is rotatably mounted in a housing wall of the gear housing 10, the axis of rotation of which is essentially perpendicular to the two shafts 11 and 13, the bevel gear 19 meshing with both the bevel gear 16 and the bevel gear 17.
  • a ring gear 20 is formed, the center of which coincides with the axis of the gear shafts 11 and 13.
  • the ring gear 20 meshes with a pinion 21
  • Three-phase servo motor 22 which is connected to a controller 23.
  • the controller 23 controls the three-phase servo motor as a function of the respective angle of rotation of the eccentric shaft 7, for which purpose an angle encoder 24 is connected, which taps the movement of the rotary star 9 due to the synchronous transmission of the rotary movement of the eccentric shaft 7.
  • the rotary movement of the eccentric shaft 7 is transmitted to the cam roller 8 via the belt drive 6.
  • the rotary star 9 is rotated further by one division.
  • the curve groove in the cam roller 8 is dimensioned such that the turning star 9 is at rest in good time before the punching process begins, i.e. in good time before the bottom dead center of the carriage 2, and also remains at rest until the punching process has ended and the carriage 2 has its has left bottom dead center.
  • the transmission gear 10 is driven intermittently.
