Definitions

  • the invention relates to a strapping device for steel straps in particular, with a tensioning unit and a closer unit, and with a single motor, in particular an electric motor, which acts on both the tensioning unit and the closer unit.
  • Strapping devices for steel straps are used, for example, to strap metal strap coils, steel girders, etc.
  • the objects to be strapped are usually fed with a conveyor and strapped with the steel band.
  • the steel belt is usually guided around the objects in question with the aid of a belt guide frame.
  • the steel band in question is then tensioned with the aid of the tensioning unit and closed at the ends of the band to be connected using the closer unit.
  • it is also possible to couple the relevant tape ends to one another via a sleeveless connection as is the case with the prior art according to the generic type WO 2016/014167 A1 describes.
  • the invention is based on the technical problem of developing such a strapping device, in particular for steel straps, in such a way that a structurally simple structure is realized and the change from the tensioning function to the closer function and vice versa can take place simply, precisely and intuitively.
  • a generic strapping device within the scope of the invention is characterized in that the tensioning unit and the closer unit are each equipped with an alternately working freewheel.
  • both the tensioning unit and the closing unit are each equipped with a freewheel.
  • the freewheel belonging to the clamping unit is called the clamping unit freewheel.
  • the freewheel of the closer unit is a closer unit freewheel.
  • the two freewheels work alternately, i.e. either only the closer unit freewheel or only the clamping unit freewheel.
  • the closer unit freewheel and the tensioning unit freewheel depending on the direction of rotation of the motor press either the clamping unit or the closer unit.
  • the invention is based on the knowledge that the single motor as the drive for the strapping device is typically designed as an electric motor.
  • other motors are also conceivable in this context, such as a pneumatic motor, although not preferred.
  • an electric motor typically used at this point is characterized in that in this way the strapping device can be operated entirely independently. Additional compressed air lines as with a pneumatic motor are not required.
  • the design can be made in such a way that the electric motor is fed with the necessary electrical energy with the aid of one or more accumulators.
  • wired solutions are in principle also covered by the invention. In this case, the electric motor is supplied with the required electrical energy via a power cable.
  • the accumulator in question or the plurality of accumulators can be detachably and exchangeably arranged and held in a housing of the strapping device.
  • the battery in question can be recharged in an additional charging cradle, for example.
  • the procedure is that the closer unit freewheel locks in a counterclockwise direction and the clamping unit freewheel locks in a clockwise direction, or vice versa.
  • the invention is based on the knowledge that the electric motor typically used at this point rotates counterclockwise or clockwise and consequently transmits this respective rotary movement either to the clamping unit or the closer unit, specifically in the sense of an "either-or" link.
  • the two freewheels ensure that.
  • the electric motor can also work with the interposition of a gear on the clamping unit and the closer unit.
  • the closing unit is usually acted upon on the output side of the tensioning unit with the interposition of a transmission means.
  • the design is also made such that the transmission means works with the implementation of a reduction gear on the closer unit. That is, during operation of the closer unit and consequently a closing process of the belt ends to be connected, in particular the steel belt, there is, as it were, a double reduction of the high-speed rotary movements of the electric motor.
  • the gearbox following the electric motor provides an initial reduction.
  • the transmission means is provided between the closer unit and the gear, realizing a second reduction gear.
  • This second reduction gear as part of the transmission means is implemented as a rule in such a way that the flexible transmission means has two Gears is performed, which provide the desired reduction, consequently act as a reduction gear.
  • a toothed belt or a chain for example, can be used as the transmission means as the flexible transmission means.
  • the invention takes into account the fact that particularly high torques must be made available for the operation of the closer unit. This is made available by the invention through the two reduction gears.
  • the closer unit is generally arranged in the axial direction of the electric motor and, if applicable, of the transmission.
  • the clamping unit is generally located perpendicular to the axial direction of the electric motor and, if applicable, of the gearbox.
  • the invention is based on the knowledge that the strapping band or steel band generally has to be guided through the strapping device in the axial direction or transversely to the axial direction of the electric motor and consequently has to be tensioned in this axial direction or transversely thereto. This is ensured by the clamping unit, which is mostly oriented perpendicular to the axial direction of the electric motor.
  • the tensioning unit may also be arranged perpendicular to the transmission.
  • the closer unit which is usually equipped with two closing tongs, can ensure the desired closing of the strap ends to be connected.
  • the two locking pliers each work transversely to the longitudinal extension of the band.
  • the closure can take place directly, for example, by crimping the ends of the strap to be connected or by a closure sleeve pushed and squeezed over the two strap ends to be connected.
  • the closer unit is also equipped with at least one cam for acting on the two locking tongs.
  • the closer unit can be designed as a whole as an exchangeable closer module that can be decoupled from the drive and coupled to the drive, or it can constitute a component of such a closer module. This makes it possible to remove the closer module or the closer unit itself from the drive and, for example, to revise, retool or service it.
  • the closer module can be detachably connected as a whole to an axial arm.
  • the motor including the optional gearbox runs parallel to the axial arm and is connected to the axial arm with a mounting flange.
  • the clamping unit is usually equipped with a worm wheel.
  • the worm wheel in turn meshes with an output worm on an output shaft of the motor or transmission.
  • the worm wheel can be directly and automatically oriented perpendicularly in comparison to the output worm and thus the output shaft of the motor, as is the case for the clamping unit as a whole, which is oriented perpendicular to the axial direction of the electric motor and possibly the transmission.
  • the result is a strapping device for steel straps, in particular, which is characterized by a compact and structurally simple structure. This is because the use of the alternating freewheels ensures that, depending on the direction of rotation of the motor or electric motor, either only the clamping unit or the closer unit is acted upon by the electric motor in question. This allows you to change the direction of rotation of the electric motor between a clamping process and a Differentiate and switch over the closing process, without the need for complicated mechanics or kinematics.
  • the change in the direction of rotation of the electric motor can optionally be carried out by an operator. But it is also possible to have an automatic switchover.
  • the tension in the steel strip or generally in the strapping can be measured using a sensor or by measuring the current consumption of the electric motor during the tensioning process.
  • the figures show a strapping device which is particularly suitable and provided for strapping objects with the aid of one or more steel straps 1.
  • the steel band 1 shown is looped around the objects to be strapped, tensioned with the aid of the strapping device shown and the ends of the steel band 1 are subsequently closed. This can be done using an in the Fig. 2 shown closure sleeve 2 happen, which is pushed over the band ends to be connected of the steel band 1 and pressed or crimped with them.
  • the band ends of the steel band 1 can also be pressed together without a sleeve, but this is not shown.
  • the strapping device has a tensioning unit 3, 4 and a closer unit 5, 6, 7.
  • a single motor 8 is implemented which, according to the exemplary embodiment, is an electric motor 8.
  • the electric motor 8 is used with the interposition of a gear 9 on the one hand to act on the clamping unit 3, 4 and on the other hand the closing unit 5, 6, 7, alternately and alternately, as will be described in more detail below.
  • the tensioning unit 3, 4 and the closer unit 5, 6, 7 are each equipped with an alternately working freewheel 10, 11.
  • a tensioning unit freewheel 10 on the one hand and a closer unit freewheel 11 on the other hand are implemented.
  • both freewheels 10, 11 act on either the clamping unit 3, 4 or the closer unit 5, 6, 7.
  • the design is so affected that the closer unit freewheel 11 in the Fig. 2 Closing process shown or the closing unit 5, 6, 7 locks counterclockwise.
  • a clockwise lock is provided for the tensioning unit freewheel 10. Consequently, the closer unit freewheel 11 runs free in clockwise direction, while the tension unit freewheel 10 has a freewheel in the counterclockwise direction.
  • the closing unit 5, 6, 7 is acted upon on the output side of the clamping unit 3, 4 with the interposition of a transmission means 12.
  • the transmission means 12 actually works with the implementation of a reduction gear 13, 14 on the closer unit 5, 6, 7.
  • the reduction gear 13, 14 is two gears 13, 14 over which the flexible transmission means 12 designed as a toothed belt is guided becomes.
  • the reduction of the reduction gear 13, 14 implemented at this point results from the fact that a first gear 13 connected to the electric motor 8 and the interposed gear 9 on the drive side is equipped with a smaller number of teeth than a second gear 14, which is equipped with the aid of the transmission means or the toothed belt 12 is set up to act on the closer unit 5, 6, 7.
  • a reduction i 1 or less is usually used at this point.
  • the closer unit 5, 6, 7 is arranged in the axial direction of the electric motor 8 and, if applicable, of the transmission 9.
  • a total of an axial arm 15 is implemented in this axial direction.
  • the clamping unit 3, 4 is oriented perpendicular to the axial direction of the electric motor 8 including the gear 9 or the axial boom 15.
  • a mounting flange 16 is provided according to the embodiment, with the Help the motor 8 including the downstream gear 9 is connected parallel to the axial arm 15 with this.
  • the axial arm 15 and the fastening flange 16 can also form a structural unit or a single component.
  • the closer unit 5, 6, 7 including reduction gears 13, 14 and flexible transmission means or toothed belt 12 as a whole as closer module 5, 6, 7; 12; 13, 14 is formed.
  • the axial boom 15 can be designed to be detachable and coupled and uncoupled from a link 17.
  • the closer unit 5, 6, 7, including the link 17 that supports and supports it can be removed from the axial arm 15, the motor 8 including the gear 9 and the reduction gear 13, 14 as well as the transmission means 12 and can be coupled to it again if necessary.
  • the reduction gear 13, 14 is designed as a worm gear or contains one.
  • a gear 13 connected to the transmission 9 may still be implemented, which works with the aid of the transmission means or toothed belt 12 on the further gear 14, both gears 13, 14 in this case transversely to the axial direction of the electric motor 8 and the downstream gear 9 are arranged.
  • the reduction gear 13, 14 implemented in this way then in turn works via a worm shaft on a further gear, with the aid of which the closer unit 5, 6, 7 is then acted as a whole.
  • the closer unit 5, 6, 7, including the link 17 that supports and supports it can be removed from the axial arm 15 and coupled with it again if necessary.
  • the closer unit 5, 6, 7 are removed from the motor 8, including the gear 9 and the reduction gear 13, 14 connected to the axial boom 15, and coupled with it again if necessary.
  • the clamping drive or the clamping function is shown here.
  • the clockwise rotation of the electric motor 8 and of the downstream gear 9 is transmitted to a worm wheel 4 via an output worm 3 fastened on the output shaft.
  • the output worm 3 rotates on the output shaft oriented in the axial direction.
  • the worm wheel 4 is oriented vertically and thereby executes a rotary movement likewise in a clockwise direction.
  • the closer unit freewheel 11 runs free during this process. Because the clockwise rotation of the output shaft of the electric motor 8 including the downstream gear 9 is transmitted via the first gear 13 to the second gear 14 with the interposition of the toothed belt 12.
  • the second gear wheel 14, which is equipped with the closer unit freewheel 11, also rotates clockwise. Since the closer unit freewheel 11 freewheels clockwise, two are in the Fig. 2
  • the locking pliers 7 shown and providing for the locking process of the steel strip 1 as part of the locking unit 5, 6, 7 are not acted upon.
  • the control unit 18 ensures that the electric motor 8 is switched over in terms of its direction of rotation. As a result of this, the electric motor 8 accordingly performs a counterclockwise rotation, as in the associated one Fig. 2 is shown. Now the electric motor 8 including the gear 9 ensures that the closer unit 5, 6, 7 is controlled. Because the one in the Fig. 2 The counterclockwise rotation of the electric motor 8 shown on the output side of the transmission 9 also causes the output worm 3 arranged on the output shaft to rotate counterclockwise. This has the consequence that the tensioning unit freewheel 10 rotates counterclockwise and is thus free-running. The one or more rollers or tensioning wheels are consequently no longer acted upon.
  • the counterclockwise rotation of the electric motor 8 including the downstream gear 9 ensures that the closer unit freewheel 11 rotates counterclockwise and is consequently blocked.
  • rotations of the second gear 14 are transmitted to a cam 5 as part of the closer unit 5, 6, 7.
  • the cam 5 for its part works on an interposed lever chain 6, which overall ensures that the previously mentioned locking tongs 7 are moved towards one another and are closed transversely to the longitudinal extension of the steel strip 1.
  • the Fig. 2 indicated closure sleeve 2 is pressed onto the band ends of the steel band 1 to be connected.
  • the tape ends are permanently plastically deformed and coupled to one another.
  • the electric motor 8 is coupled as a whole to an accumulator, not shown, which serves to supply it with electrical energy.
  • the accumulator may be arranged in a detachable or fixed manner in a housing.
  • the strapping device shown can work as a handheld device or as a stationary device.
  • the closer unit 5, 6, 7 as part of the closer module 5, 6, 7; 12; 13, 14 is thus designed overall as a module that can be decoupled from the motor 8 and coupled to the motor 8 as well as being exchangeable.
