Definitions

  • the invention relates to a tensioning and closing device for strapping an object with a strap according to the preamble of claim 1.
  • the device is the drive motor directly with the tension wheel connected.
  • German patent specification DE 32 29 870 C2 is a strap strapping device described in which a single drive motor for the alternative drive of the tensioning wheel or the closing device which drive motor is provided together with a reduction gear in a gear housing as Unit can be placed on the housing of the strapping device and can be connected to it, so that the drive device can be exchanged.
  • the drive motor and the reduction gear can be parallel to each other and also arranged parallel to the tension shaft and with each other via gears be connected. They can also be arranged coaxially to one another and via one Angular gear be connected to the tension wheel.
  • the invention has for its object a generic To create tensioning and closing device, in which the drive of the tensioning wheel is simple and one has high efficiency.
  • the tensioning wheel an inner recess
  • the gearbox at least is partially housed in the recess of the tensioning wheel. This saves a lot of space.
  • the Device with a separate drive motor for the closing device Mistake. Every motor can do the best be adapted to the respective requirements.
  • Both drive motors can be powered by a battery.
  • the height Efficiency of the tensioning wheel drive according to the invention enables economical battery operation.
  • FIG. 1 shows the tensioning and closing device according to the invention schematically in a perspective view reproduced. It comprises a housing 1 with a Base plate 2 on which a clamping unit 3 and a not shown known sealing unit are attached.
  • the device with the base plate 2 on one with a thermoplastic plastic tape, for example object to be strapped.
  • the tape is around put the object around, and two of it to be locked Ends are held by the clamping unit 3.
  • the sealing unit is suitable in a manner known per se the two overlapping ends after tensioning the tape to connect, for example by friction welding. If the tape is unwound from a supply roll, one Subordinate separation device, not shown, arranged downstream of the clamping unit 3 be to separate the required band section from the Supply roll.
  • the clamping unit 3 has a fixed tooth plate 4 for laying on the lower end of the tape to be closed.
  • a movable one Tension shoe 5 is serrated on the underside for cooperation with the tooth plate 4.
  • the top of the tension shoe 5 has a support surface 10 which is suitable for placing the upper end of the tape to be closed.
  • a pivotable rocker 6 is provided with a serrated, rotatable about a clamping axis 7, drivable Tensioning wheel 8 for pressing the upper end of the band against the tensioning shoe 5 and for grasping the upper end when rotating of the tensioning wheel 8, so that the band in the tensioning direction 9 in is tensioned in a known manner.
  • the axis of rotation of the pivotable rocker 6 is in the embodiment shown about between the tension shoe 5 and the Base plate 2 and in the clamping direction 9 behind the support surface 10 of the tension shoe 5 arranged. This allows the rocker 6 with the tensioning wheel 8 without great effort in any position of use the device, especially when the belt is tensioned again be lifted off.
  • this arrangement of the rocker 6 is not essential for the invention.
  • the rocker 6 with the tensioning wheel 8 is actuated by a Lever 11 pivotable. If in the tension direction 9 to the rear is pivoted, the clamping shoe 5 can be lifted off the tooth plate 4, so that the lower end of the tape to be closed inserted between the tooth plate 4 and the clamping shoe 5 can be. Then the lower end of the band is pinched, and the tensioning wheel 8 is held at a distance from the tensioning shoe 5, so that the upper end of the tape to be closed between the tensioning shoe 5 and the tensioning wheel 8 can be inserted. When the rocker 6 is pivoted forward in the clamping direction 9 is, the tensioning wheel 8 against the bearing surface of the tensioning shoe 5 pressed and clamps the upper end of the tape so that by rotating the tensioning wheel 8, the tensioning process is carried out can be.
  • the drive of the tensioning wheel 8 for tensioning the band, if that Tensioning wheel 8 rests on tensioning shoe 5 is carried out by means of a Motor 12, which is arranged coaxially with the tensioning wheel 8 and via a coaxially arranged with the tensioning wheel 8, known transmission, for example a planetary gear, is connected to the tensioning wheel 8.
  • the speed of the Drive motor 12 is powered by the planetary gear supported coaxially with the clamping axis 7 under the rocker hood 13 is reduced to the desired level.
  • This arrangement enables a very compact design and a high overall efficiency of the tension drive. This is with a clamping unit with battery operation essential.
  • Both the closing unit and the clamping unit 3 are motor-driven, the drive motor 12 of the Clamping device and also the motor of the closing device can be powered by a battery.
  • an electric motor can be used as the drive motor 12 or an air motor can be used.
  • a brushless DC motor selected with the Direct current of the battery can be operated.
  • the torque the drive motor 12 of the tensioning wheel 8 is adjustable, so that appropriate for different objects to be strapped Band tension ranges can be set.
  • FIG. 2 shows a sectional view of the inventive Contraption.
  • the drive motor 12 is, for example, a brushless one DC motor, which is coaxial with the tensioning wheel 8 and is arranged with the transmission.
  • the gearbox is in the shown embodiment a known, two-stage Planetary gear.
  • the motor pinion 14 of the drive motor 12 works with the planetary gear 15 of the first reduction stage together.
  • the planet gears 15 of the first stage are on the planet gear carrier 16 stored the first stage.
  • the speed of the drive motor 12 continues to increase the desired size is reduced and the tensioning wheel 8 is driven.
  • the tensioning wheel 8 advantageously has an inner recess, and the planetary gear is partially space-saving in this Recess housed.
  • the tensioning wheel 8 is for example cylindrical or ring-shaped or as a cylindrical Ring formed, the inside is serrated is.
  • the rocker 6 is closed by means of a cover 20.
  • the device is equipped with a known, not shown, separate drive motor for the closing device Mistake. Therefore, each engine can optimally match the respective Requirements are adjusted. Both drive motors are by means of a single, also known per se and not shown batteries can be fed. The rational battery operation is due to the high efficiency of the tensioning wheel drive according to the invention enables.
  • FIG. 3 is an exploded perspective view of the Tension drive of the device reproduced.
  • the planet gears 15 and the planet carrier 16 form the first reduction stage.
  • the planet carrier 17 and the planet gears 19 form the second reduction stage.
  • you can too another gear can be used, for example a harmonic Transmission ("harmonic drive").
