Definitions

  • the invention relates to a strapping device with at least one drive motor, furthermore with at least one drive roller for a strapping band supplied from a band supply, as well as with at least one tensioning roller for tensioning the strapping band guided around the material to be strapped, and with a locking unit for connecting the band ends of the around the strapping around the good, with a pivoting coulisse being provided which applies at least one counter roller to the drive roller for belt drive or to the tension roller for belt tensioning, and the drive motor drives both the drive roller and the tension roller.
  • the strapping tape is first passed around the relevant item to be strapped. This is done with the help of the drive roller. The strapping is then tensioned using the tensioning roller. In this tensioned state, a loop of the strapping tape is separated from the tape supply. In addition, the two ends of the strap are pressed against each other and connected to one another in the closure unit. If the strapping band is made of plastic, for example, the band ends are connected by welding, for example by friction welding.
  • the drive roller and also the tension roller are each equipped with a counter roller, so there are a pair of interacting drive rollers as well as a pair of interacting tensioning rollers that clamp the strapping between them.
  • the tensioning roller in conjunction with the associated counter roller, ensures that the strapping tape is tensioned after it has been guided around the material to be strapped. This is described in detail in the prior art according to DE 10 2008 004 118 B4 described.
  • the well-known teaching according to the DE 10 2008 004 118 B4 uses overall only a single drive motor, on whose motor shaft one of the drive rollers is arranged, that is to say the drive roller itself or the counter roller interacting with the drive roller or the so-called drive counter roller.
  • a movement transmission means is provided which transmits the movement of the motor shaft of the drive motor to a reduction gear.
  • the reduction gear drives at least one of the tensioning rollers, that is to say the tensioning roller or also the associated counter-roller or tensioning-counter-roller.
  • the invention expressly does not exclude, for example, two drive motors in this context.
  • a drive motor can be used to drive the tensioning roller or the tensioning rollers and a further drive motor can be used to drive the drive roller or the drive rollers.
  • WO 2015/117255 A1 describes a strapping device which, with a drive, serves to drive a tape feed device, a tape retraction device and finally a tensioning device.
  • the strapping head of the strapping device should be designed to be particularly compact.
  • an eccentric is arranged which carries a counter-roller which can be set against the tensioning roller on the one hand and the drive roller on the other hand.
  • GB 2 041 869 A deals with a strapping device in which the interaction of two drive rollers is described. One of the drive rollers can be adjusted and removed again with the help of a lifting arrangement.
  • the invention is based on the technical problem of further developing such a strapping device in such a way that, taking into account a compact structure, there is the possibility of being able to switch quickly and functionally reliably between a drive of the strapping band and a tensioning process without any problems.
  • a generic strapping device within the scope of the invention is characterized in that the link carries at least two counter-rollers, namely a drive counter-roller and a tensioning-counter-roller, that furthermore the drive motor, via a gear, the tensioning roller and, with the interposition of a shaft bearing sleeve, the The drive roller is acted upon, and that the link is rotatably mounted on a flange, the drive motor, the gear and the shaft bearing sleeve each being connected to the flange parallel to one another and predominantly perpendicularly upright.
  • the procedure is generally such that either the belt drive or the belt tensioning is carried out.
  • the belt drive and the belt tensioning can also at least partially overlap in time.
  • the belt drive takes place first. First when the tape drive is complete, the tape tensioning is switched over, as it were.
  • the pivotable gate is therefore initially used.
  • the pivotable link is usually rotatably mounted on or on a front side of the flange.
  • the at least one drive motor is located on the rear side of the flange.
  • two drive motors can also be implemented at this point, namely one drive motor for the drive roller and another drive motor for the tensioning roller. According to the invention, however, a single drive motor is used here, which drives both the drive roller and the tension roller in each case.
  • At least two counter rollers are provided which are carried by the backdrop.
  • the counter rollers in question are each rotatably connected to the backdrop. That is, the backdrop carries the at least two counter-rollers, which are a drive counter-roller and a tensioning-counter roller.
  • the drive counter roller When it rests on the drive roller, the drive counter roller ensures that the strapping band clamped between the drive roller and the drive counter roller is transported.
  • the tensioning counter-roller in connection with the tensioning roller ensures that the strapping clamped in between is tensioned or can be tensioned.
  • Both counter-rollers that is to say the drive counter-roller and the tensioning-counter-roller, are each non-driven and only rotatably mounted on the link. Either the drive roller or the tensioning roller alone is responsible for the associated drive.
  • the change between the belt drive and the belt tensioning takes place in an unconstrained manner in that either the drive counter-roller is applied to the drive roller or, alternatively, the tensioning counter-roller is applied to the tensioning roller. Since the counter roller that is no longer required is lifted when changing from belt drive to belt tensioning, both the drive roller and the tensioning roller can advantageously continue to be operated and set in rotation with the aid of the one drive motor. This means that when the belt is being driven, the strap is clamped between the drive roller and the drive counter roller and transported. Since in this case the tensioning counter-roller is lifted from the tensioning roller and spaced apart, the belt can slide over the tensioning roller, which is still rotating, without any problems in this case.
  • the belt tensioning corresponds to the fact that the tensioning counter-roller is set against the tensioning roller with the aid of the link and the belt can be clamped and tensioned. Since the drive counter roller is lifted and removed from the drive roller, the drive roller can continue to rotate unchanged and the strapping can be guided over the drive roller more or less without resistance.
  • the backdrop is generally L-shaped.
  • the backdrop usually has a rotatable bearing at the end of its long L-leg, which is usually observed with respect to the flange already mentioned above.
  • generally pivoting movements of the L-shaped link are sufficient, which correspond to a pivoting angle of less than 20 degrees and preferably even of 10 degrees and less. Such swivel angles can be implemented quickly and mechanically in a simple manner.
  • the design is made in such a way that the link is not only rotatably mounted at the end of its long L-leg, but also one of the two counter-rollers is mounted on the long L-leg, while the other counter-roller is mounted on the short L-leg .
  • an arrangement has proven to be particularly favorable in which the drive counter-roller is connected approximately in the middle to the long L-leg of the L-shaped link.
  • the tensioning counter-roller is usually located at the end of the short L-leg.
  • the gate is generally moved against the force of at least one spring.
  • the spring ensures that the link in its neutral position assumes, for example, a position in which both counter rollers are spaced apart from the drive roller on the one hand and from the tensioning roller on the other.
  • an eccentric is generally provided for pivoting the gate.
  • the eccentric is advantageously designed as a cam or has such a cam.
  • the cam can work on a cam follower lever, for example, via a cam follower.
  • the cam roller lever in turn ensures that the L-shaped link is pivoted against the force of the spring assigned to it.
  • a “single” drive motor which drives both the drive roller and the tension roller.
  • the drive motor acts on the tensioning roller via the transmission.
  • the gear is advantageously a reduction gear, because for tensioning the strapping band after it has been guided around the material to be strapped it is usually high Torques are required and the drive motor is generally designed as a high-speed electric motor.
  • the drive motor acts on the drive roller with the interposition of the shaft bearing sleeve.
  • the drive motor is coupled to the gearbox on the one hand and to the shaft bearing sleeve on the other hand generally via a movement transmission means.
  • the movement transmission means can be a belt and, in particular, a toothed belt.
  • pulleys or toothed belt pulleys ensure the corresponding transmission on the one hand on the output shaft of the drive motor and on the other hand on an input shaft of the transmission and an input shaft of the shaft bearing sleeve.
  • the shaft bearing sleeve, the gear unit and the drive motor can be fitted in a predominantly matching alignment practically parallel to one another on the rear side of the flange.
  • a particularly compact design is made available and the weight distribution compared to the flange can be optimized.
  • a strapping device is made available that is compact and works reliably. This is particularly true in the event that straps made of plastic are to be processed.
  • the strapping device described can also be used in connection with, for example, steel straps.
  • straps that are not made or made of neither steel nor plastic, for example those based on natural raw materials such as natural polymers, are of course also conceivable.
  • Mixed forms can also be used as the strapping material become. Due to the compact and compact design, the strapping device described can in principle be used both for so-called handheld devices and for stationary strapping machines. This is where the main advantages can be seen.

  • the drive motor 4 the gear 7 and the shaft bearing sleeve 8 are each connected to the flange 9 parallel to one another and predominantly perpendicularly upright. This enables an optimal weight distribution to be achieved.
  • the attachment of the drive motor 4 "next to" the gear 7 as well as the shaft bearing sleeve 8 ensures that the aforementioned elements 4, 7, 8 require relatively little installation space perpendicular to the flange 9.
