Definitions

  • the invention relates to a machine for strapping palletized packaged goods including the pallet with a strapping agent, in particular a thermoplastic band, consisting essentially of a portal, a bayonet supplementing this to a circumferential band guide channel for the strapping agent and an assembly for the preparation, conveying and the closure of the strapping means, both the bayonet and the unit are each equipped with a drive motor and a linear guide for their essentially horizontal relative movement to the packaged goods and portal.
  • a strapping agent in particular a thermoplastic band, consisting essentially of a portal, a bayonet supplementing this to a circumferential band guide channel for the strapping agent and an assembly for the preparation, conveying and the closure of the strapping means
  • both the bayonet and the unit are each equipped with a drive motor and a linear guide for their essentially horizontal relative movement to the packaged goods and portal.
  • the linear guides are realized by means of ball screws. Electric motors each drive a threaded spindle along which a ball screw nut mounted on it is adjusted, to which the movable machine parts are in turn attached.
  • the bayonet and / or unit is driven by chain drives controlled by end positions or pneumatic cable cylinders.
  • the invention is therefore based on the object of making available a machine which is outlined in the preamble of claim 1 and which is capable of fulfilling the safety requirements in a considerably simplified manner and which can be used in the technically inexpensive linear guides.
  • the invention solves this problem primarily and essentially by using rotating field magnets as drive motors for the bayonet and the unit.
  • Three-phase magnets are three-phase motors with squirrel-cage rotors, the stators of which are 'overwound', i.e. are provided with a significantly larger number of turns than usual. They are designed electrically so that they can be used at rated voltage with a braked shaft in continuous and intermittent operation with unlimited duty cycle and develop their greatest torque (standstill torque). In principle, you could compare a rotating field magnet with an electric spring with infinite spring travel.
  • the invention utilizes these properties of rotating field magnets, which were previously used, for example, to drive church bells or for the winding devices on drums of trailing cables for cranes, to an astonishingly advantageous extent to control the linear movements of the bayonet and / or assembly.
  • a rotating field magnet as a direct drive motor for the bayonet and / or unit is considerably simpler and therefore less expensive than, in particular, a ball screw drive or a pneumatic cable cylinder, which besides the electrical connection, which is in any case necessary for the machine, also requires a compressed air supply.
  • the linear drive can consequently be designed in a simplest embodiment, which is characterized approximately in that a drive pinion is arranged on the shaft of the rotating field magnet, which meshes with a rack attached to the bayonet or to the unit. It is of further advantage, in particular for reasons of constructive simplification, if the toothed rack is connected to carriages guided on a carrier rail by means of rollers.
  • a pallet strapping machine designated overall by 10, includes a portal 11 with posts 12 and 13 and a bar 14, the actual machine unit 15 and a bayonet 16.
  • the palletized packaged goods 17/18 are first moved into the portal by means of a transport device indicated by 20, such as roller conveyors. Then the bayonet 16, which is waiting in the rest position on the right in FIG. 1, passes under the pallet 17 and docks at 21 on the post 12. In the usual way, the assembly now shoots the strapping means in the direction of circulation 22 through the strapping channel 19 until the front end of the strapping means is inserted into a closure head 23 of the assembly 15 and is held there. Now the unit 15 moves against that Packaged goods 18 in the position 15 'shown in dashed lines, and the strapping means is then withdrawn against its weft direction, thus pulled out of the strapping channel and finally tightened around the packaged goods. The overlapping strapping sections are ultimately firmly connected to one another in the closure head 23, that is to say generally thermally welded.
  • the drive 24 for the bayonet 16 and the drive 25 for the assembly 15 are new and essential to the invention, also in connection with their linear guides 31 and 38.
  • a rotating field magnet 26 serves as the drive motor for the bayonet 16.
  • a pinion 28 is rotatably mounted on its shaft 27 (FIG. 2) and meshes with a toothed rack 29 fastened under the bayonet 16. With 30 the strapping channel in the bayonet 16 is designated, which is mounted on a very simple linear guide 31.
  • the linear guide 31 comprises a rail 33 carried by two supports 32 standing on the floor with rail heads 34 made of round steel bars, on which rollers 35 rotatably mounted on carriages 36 run.
  • the bayonet 16 is in turn attached to the carriage.
  • the pinion 28 drives the bayonet mounted on the linear guide described and, depending on the direction of rotation, either pushes it forward or pulls it back.
  • a very similar drive is provided for the assembly 15, whose rotating field magnet is designated 37 and its linear guide is designated 38 (FIG. 1).
  • the shaft of the rotating field magnet 37 meshes with a rack secured under the assembly 15.
  • the linear guide 38 is attached to the top of the unit 15. Thereby, i.e. due to the spatial separation of drive and guidance, a very stable position of the assembly 15 is achieved.
  • the guide rail 39 is connected to the unit 15 in a uniform movement, while the rollers 40 are mounted on a bracket 41 held in a fixed position.
