Definitions
- the invention relates to a device for guiding an expanding belt, comprising a winding roller rotatable about a rotation axis and a spreading belt which can be wound onto the winding roller and unwound from the winding roller.
- a spreader is a cambered belt in the transverse direction which, when unloaded, bulges or curls about an axis parallel to its longitudinal axis.
- Such expansion bands are usually made of metal or plastic. As a result of their curvature, they show considerable compressive and bending rigidity, but they are also very rigid, unlike a flat band, which can be loaded only on train, but not on thrust.
- a device for guiding such a spreading belt comprises a winding roller rotatable about an axis of rotation and a spreading belt which can be unwound onto the winding roller and can be unwound from the winding roller.
- the spreader In the wound state, the spreader is flattened, as soon as it is unwound and ultimately charged only on pressure or train, it bulges.
- Such a device for guiding a spreader in conjunction with a suitable winding roller drive, so a Sp Dahlbandantrieb can be used wherever a sliding and a pulling movement is required. From DE 10 2006 059 187 A1, for example, the linear motion obtained therefrom of a guide carriage of a linear motion carriage which can be moved on a guide rail is known. management module known.
- the winding roll has a special geometry (see, for example, DE 38 38 724 A1).
- the winding roll has a winding groove, the groove base is designed as a spiral, wherein the band rests freely in the undercut. Laterally two side shelves are provided, between which the spreader is clamped. This clamping between the two side rims is required lent to be able to exert a train or pressure on the tape upon rotation of the winding roll, so it can move defined.
- this board contour is causing great problems, since the fatigue strength due to high wear, resulting from the permanent, jamming respectively rubbing or scraping stress during winding and unwinding is not given.
- the invention is based on the problem to provide a device of the type mentioned above, which allows a simple winding and unwinding of a spreader on and from a winding roll without the aforementioned wear problems.
- the winding roll is assigned a pair of rollers or rollers through which the spreader runs, the rollers or rollers on the top and bottom attack the spreader and at least one roller or roller is driven by a drive means.
- the device according to the invention is characterized by a pair of rollers or rollers upstream of the wound reel, via which the actual unwinding and winding operation, and therefore the spreading belt movement in the axial direction, is obtained.
- the spreader runs, based on the unwinding, of the no specially shaped side walls having winding roll initially between the immediately upstream roller or roller pair, it is still between the rollers or rollers in the flattened state.
- the distance between the two rollers or rollers to each other is such that they rest sufficiently firmly above and below the spreader, so therefore a sufficiently good frictional contact is given.
- At least one of the two rollers or the two rollers is now rotationally driven via a drive means, for example an electromotive drive or via a belt drive, etc., which leads to the spreading belt being pushed over it by the roller or roller pair.
- a drive means for example an electromotive drive or via a belt drive, etc.
- rollers or rollers are expediently made of plastic, of course, such a material is chosen, which has a sufficiently good frictional contact with the spread band formed of metal or plastic, so that there is no slippage. This means that the plastic has a certain softness and adhesiveness.
- the rollers or rollers made of metal and provided with a corresponding plastic coating, which respectively has a sufficiently good adhesion To provide layering, which develops a sufficiently good adhesion or friction relative to the spreader.
- the roller or roller pair can be coupled via a drive connection with the winding roller or the axis of rotation of the winding roller. That is, the wrapping roller drive, which is ultimately required to move the winding roller parallel to the drive of the roller or roller pair to define or unwind the belt, is derived from the drive of the roller or roller of the roller or roller pair , Conveniently, this drive connection is a friction gear or it comprises such a friction gear. This is particularly advantageous, as this drive connection ultimately must not be rigid, since the winding radius of the winding roll changes during winding and unwinding, but thus also the peripheral speed. Such Reibradan- drive now easily allows compensation by a defined slip is made possible, so that the winding roll is always driven at the right speed.
- a particularly expedient development of the invention provides to carry out the expansion band of two cambered, mutually oppositely arranged and interconnected along their edges band sections.
- the spreader is thus designed with particular advantage as a double-layer tape, which can be flattened by transverse load, but bulges in the unloaded state due to the crowning of the two band sections, to a hollow, in cross-section substantially oval shape.
- For the two Sp Schwarzbandabitese are based on their crowns, arranged opposite to each other, so that there is in the unloaded state of the hollow body.
- Such a double-layered tape has proven to be particularly rigid or rigid, since any forces which would lead to buckling or flattening, etc., would ultimately have to be so great that they would have to overcome double tape embossing.
- connection to the drive according to the invention can result in a simply constructed spread-band system.
- Device respectively a Sp Rudbandantrieb be created, which is also able to transfer high tensile and in particular thrust forces at the same time.
- the two clamping portions may be connected together along their edges by any joining techniques, preferably, they are welded together, which is possible both in execution of the band sections of metal and plastic. Conceivable is a laser welding, spot welding, pressure welding, etc.
- the band sections can also be soldered together, is also conceivable riveting, gluing or flanging, etc.
- FIG. 1 shows a schematic illustration of a device according to the invention of a first embodiment with a "one-piece" spreading band
- Figure 2 shows a second embodiment of a device according to the invention with a "two-part" expansion band consisting of two connected Sp Schwarzbandaboughen, and
- FIG. 3 shows a sectional view through the spreader belt from FIG. 2, FIG. 3
- Fig. 3a shows the spreader in the compressed state and Fig. 3b shows the spreader in the unloaded, bulging state.
- FIG. 1 shows a device 1 according to the invention for guiding or moving an expanding belt 2, comprising a winding roller 3, which is rotatable about an axis of rotation 4.
- the spreader 2 is wound up in the compressed state, from this it can be unwound or wound up after unwinding again.
- the winding roll 3 which may be designed as a simple cylindrical roller, but if necessary can have two simple side walls, so that forms a winding groove, the side boards but have no drive function, a roller or roller pair 5 is connected upstream, comprising a first Roller or roller 6 and a second roller or roller 7, which receive the spreading belt 2 between them. Both rollers or rollers 6, 7 engage the upper and lower sides of the spreader belt 2.
- the roller distance is therefore such that it corresponds to the thickness of the spreader 2 in the flattened state, respectively, is slightly lower in order to exercise a sufficient friction to the spreader can push it defined or pull can.
- the rollers or rollers 6, 7 may for example be made of plastic, but it may also be metal parts, which are designed with a corresponding plastic coating. The chosen material should always be selected with regard to the expansion band material to be guided, so that a sufficient friction results, which enables safe belt transport.
- roller 6 In order to be able to actively push or pull the spreading belt 2 over the roller or roller pair, one of the rollers, here the roller 6, is driven by a drive means 8, for example an electric motor 9, which for example engages directly on the axis of rotation of the roller or roller 6. drivable. Any roller rotation consequently results in a corresponding axial expansion band movement as a result of the fixed abutment of both rollers 6, 7. Depending on the direction of rotation in this case the spreading belt 2 is wound or unwound.
- a drive means 8 for example an electric motor 9 which for example engages directly on the axis of rotation of the roller or roller 6. drivable. Any roller rotation consequently results in a corresponding axial expansion band movement as a result of the fixed abutment of both rollers 6, 7.
- the spreading belt 2 is wound or unwound.
- the rotation of the roller or roller 6 also drives the winding roller 3 derived. That is, to move the spreading belt 2 not only actively the roller or roller 6 of the roller or roller pair 5 is driven, but, derived from the drive, and the winding roller 3. This is required to the tape at least for winding the spreader actively driven, but as a result of the given coupling takes place also a winding roll rotation during unwinding.
- the integration of the friction gear 1 1 makes it possible to compensate for the resulting due to the increasing or decreasing winding radius when winding or unwinding of the spreader 2 resulting winding speed change, so that the band is always up and unwound with the correct voltage, so therefore the corresponding rotational speeds of the rollers or rollers 6, 7 and the winding roller 3 are correlated.
- FIG. 4 shows a device 1 according to the invention, which is identical to the device 1 from FIG. 1 in this respect. It also has a winding roll 3, on which the spreader 2 wound and from which it can be unwound. The winding roll 3 is also rotatable about a rotation axis 4.
- Assigned and upstream in turn is a pair of rollers and rollers with the rollers 6, 7, wherein the roller 6 in turn via a drive means 8, for example an electric motor 9, is driven.
- a drive connection 10 Via a drive connection 10, in turn, the rotary drive of the winding roller 3 is derived from the roller or roller drive, which in turn preferably takes place with integration of a friction gear 1 1 with the two friction wheels 12, 13.
- the spreading belt 2 is here an existing two Sp Schwarzbandabitesen 14, 15 existing, ie two-layer spread.
- Fig. 3 and in particular Fig. 3b shows are the two Sp Schwarzbandabitese 14 and 15 respectively cambered and arranged so that they are directed opposite to each other with their convex outer side. In the unloaded state, therefore, the spreader belt 2 bulges so that the two belt sections 14, 15 are pushed away from each other and the tubular shape shown in Fig. 3b results in a substantially oval cross-section.
- the Sp Schwarzbandabête 14, 15 are connected at their edges 16, 17 firmly together, for example, welded, soldered, glued or mechanically connected.
- the spreader belt sections 14, 15 or the spreader belt 2 is loaded by the roller or roller pair 5, ie thus compressed, then it likewise passes into a flat shape shown in FIG. 3a. Obviously, the two Sp Schwarzbandabête 14, 15 lie flat on each other, the width increases slightly.
- the spreading belt 2 can be wound in the same way on and from the winding roller 3.
- This quasi-hollow spreader belt is much more shear-resistant and kink-resistant than the one-part spreader belt of FIG. 2, in particular it permits the transmission of far higher thrust forces and is substantially more resistant to any external forces acting on it.
- the spreader 2 regardless of whether it is “one-piece” or “two-piece” is usually made of metal, such as a spring steel, but it can also be made of plastic.
- Figs. 1 and 2 are merely schematic representations.
- the drive connection can grip directly on the roller or roller rotation axis, but it can also be indirect, for example via an intermediate belt or the like.
- the drive connection 10 shown is only exemplary, the friction wheels 12, 13 are of course in a similar manner with the roller or roller 6 respectively whose axis of rotation and coupled to the winding roller 3, respectively, the axis of rotation 4, including, where appropriate, corresponding coupling connections and the like are provided.
