Abstract
The invention concerns a bale wrapping device comprising a wrapping platform (1) on which a bale (11) is rotatable about a horizontal axis (9) and a support frame (23), which carries at least one rotating arm (17) rotatable about a vertical axis (19) by means of a rotation drive (18, 21). In order to reduce the overall height of the rotating arm drive, it is proposed according to the invention that the rotation drive (18, 21) is arranged between the upper side (A) of the support frame (23) and the under side (B) of the rotating arm (17).
Description
- The invention concerns a bale wrapping device according to the precharacterising clause of
claim 1. - Both round and rectangular bales are wrapped. There are currently two basic bale wrapping systems in practical use. In the wrapping platform system, during rotation of the bale about a horizontal axis and simultaneous rotation about a vertical axis, sequential overlapping layers of film are laid two or three times round the entire outer surface of the bale. In the case of the rotating arm device, the bale does still lie on a type of wrapping platform which rotates the bale about its horizontal mid-axis, but the wrapping platform does not simultaneously rotate about its vertical axis. Rather, the relative rotation between bale and supply roll is generated with a rotating arm circling round the bale and carrying the film roll at its outer end.
- All the bale wrapping devices of the aforementioned type currently available on the market now use hydraulic torque motors, such as orbital motors with a gearbox attached whose output shaft is linked non-rotatably to the rotating arm for rotary drive of the rotating arm. In addition, arranged between the hydraulic motor and the gearbox is a multiple disk brake, which stops the rotating arm immediately if an appropriate signal is issued by a safety apparatus (leading shut-off handle). The braking distance of the rotating arm must not be longer after the shutting-off than the actuation path of the shut-off handle, in order to avoid accidents and injuries.
- In the case of a bale wrapping device in a brochure from the firm of Maschinenfabrik Bernard Krone GmbH entitled “Combi Pack” with the printed identification Nie 985/3/99, the gearbox is designed as a spur gear system and attached at the height of the support frame for the rotating arm on the support frame. See also DE 197 55 605 C1. Above this are arranged a multiple disk brake and a hydraulic motor.
- A further embodiment is disclosed in a brochure from the firm of Claas Vertriebsgesellschaft for the “Rundballenpressen-Wickler-Kombination Rollant 250 RC Uniwrap” with the printed identification 08/00 (Gie) German 200/1114. In this case, a hub for mounting the rotating arm is attached to a frame assembly and above the frame assembly is arranged a right angle drive with horizontal hydraulic motor.
- In addition there are rotating arm drives having a chain drive in place of a gearbox.
- All the known embodiments of rotary drives for the rotating wrapping apparatus have the great disadvantage of a large overall height.
- Since the hydraulic motor, multiple disk brake and gearbox as well as the rotating arm mounting are arranged one above the other, these structural members extend upwards relative to the support frame and form the highest point. Thus these constructions restrict the overall height of the device, which is critical particularly for wrapping devices for bale diameters about or above 1.65 m. Apart from this, the drives may easily become damaged when passing through entranceways.
- The object of the invention is to improve the rotating arm drive of bale wrapping devices.
- To achieve the stated object, the bale wrapping device of the aforementioned type is distinguished in that the rotating drive is arranged between the upper side of the support frame and the under side of the rotating arm. For further details of how the invention is configured, reference is made to the subclaims.
- In this manner, it is achieved that no components of the drive project upwards or downwards. The previous overall drive height is approximately halved.
- A simple design consists therein that a torque motor is arranged in the support frame and its drive shaft is connected directly or indirectly and non-rotatably to the rotating arm.
- In a preferred form of the invention, the rotating motor is connected to a gearbox, particularly a planetary gearbox arranged in the rotating arm. In addition, there are the following advantages:
- despite the torque motor and gearbox, the drive forms a compact modular unit
- the compactness of a planetary gearbox permits greater reductions and therefore hydraulic motors of smaller absorption capacity
- due to the greater gearing ratio, the self-locking of the gearbox when static is relatively larger, so that the load holding valves previously usually necessary are dispensed with
- modular design
- logistics-friendly
- multiple disk brake can also be integrated
- maintenance-free, since leakage oil lubrication used
- lower weight
- simple cladding possible, since design symmetrical above and below
- The invention will now be explained in more detail below with reference to exemplary embodiments. In the drawings:
- FIG. 1 is a side view of a bale wrapping device of known design,
- FIG. 2 is a side view according to FIG. 1 of a bale wrapping device with a drive according to the invention for the rotating arm of the wrapping apparatus,
- FIG. 3 is a schematic representation of a first example of a rotating arm drive,
- FIG. 4 is a schematic representation of a second example of a rotating arm drive,
- FIG. 5 is an enlarged representation, a view of the rotating arm drive according to FIGS. 2 and 3, with rotating arm and support frame partially omitted,
- FIG. 6 is a view along the direction of the arrow X in FIG. 5,
- FIG. 7 is a side view in enlarged representation of an alternative rotating arm drive with rotating arm and support frame partially omitted, and
- FIG. 8 is a view according to FIG. 7 of another example of a rotating arm drive.
- FIG. 1 shows a bale wrapping device of known design for covering a harvested crop bale with film. The bale wrapping device substantially comprises a fixed
wrapping platform 1 withdrivable conveying elements 2 and awrapping apparatus 3 with a rotatingarm 4, which is mounted in asupport frame 6 rotatable about avertical rotation axis 5 and carries afilm roll 7 at its lower end, as well as a stretch unit (not shown). - During the wrapping process the
film roll 7 is moved round in a rotation movement in arotation direction 8 about thevertical axis 5 around the harvestedcrop bale 11 which turns about ahorizontal rotation axis 9 in arotation direction 10, whereby the film is pulled off thefilm roll 7 and wrapped round the harvestedcrop bale 11. The drive of thebale 11 and the drive of the rotatingarm 4 work in a particular gearing ratio to one another such that the film layers wound around thebale 11 overlap through the simultaneous rotation of rotatingarm 4 andbale 11. - The known drive system for the rotating
arm 4 shown in FIG. 1 comprises ahydraulic motor 12, for instance a planetary roller motor, amultiple disk brake 13, a rotating arm mounting 14 in thesupport frame 6 and achain drive 15 between the rotatingarm mounting axis 5 and the output shaft of themultiple disk brake 13. Thechain drive 15,multiple disk brake 13 andhydraulic motor 12 are arranged one above the other and eccentrically relative to therotation axis 5 of the rotatingarm 4. Thehydraulic motor 12 extends upwards far beyond thesupport frame 6. - FIG. 2 shows an embodiment of the
novel drive 16 of the rotatingarm 17 with aplanetary gearbox 18 arranged coaxially with therotation axis 19 of the rotatingarm 17 and spatially between the rotating arm upper and under sides and attached by means of an add-onconsole 20 as rotating arm assembly group on the rotatingarm 17. Ahydraulic motor 21 is placed on theplanetary gearbox 18 and attached by means of an add-onconsole 22 as frame assembly to thesupport frame 23. The overall modular unit, comprising ahydraulic motor 21 and aplanetary gearbox 18 is thus arranged between the support frame upper side A and the rotating arm under side B. The gear reduction ratio of theplanetary gearbox 18 in the example shown is i=6:1, although it may be higher or lower. - FIG. 3 shows an example of the
drive 16 according to the invention for the rotatingarm 17, which drive is not shown in any more detail in FIG. 2. The drive comprises a one-stageplanetary gearbox 18 with asun gear 24, at least oneplanetary gear 26 mounted in aweb 25 and one internally gearedwheel 27. Thedrive shaft 28 of thehydraulic motor 21 arranged in fixed position on thesupport frame 23 and coaxially to therotation axis 19 of the rotatingarm 17 is linked non rotatably to thesun gear 24, which engages with several, for instance three,planetary gears 26. Theplanetary gears 26 are rotatably mounted in theweb 25 or planet support. Theweb 25 or planet support is firmly attached to thehydraulic motor 21, i.e. also linked to thesupport frame 23, and forms the stationary component of theplanetary gearing 18. Apart from thesun gear 24, theplanet gears 26 are also in engagement with the rotatably mounted internally gearedwheel 27, to which the rotatingarm 17 is attached. Arranged between thefixed position web 25 and thedrive shaft 28 of thesun gear 24 is a knownmultiple disk brake 29, whose braking effect is brought about through spring force, while its opening is brought about through the externally supplied oil pressure. It serves, for instance, to hold the rotatingarm 17 in a particular basic position when not in operation. Since themultiple disk brake 29 is arranged coaxially with therotation axis 19 of thesun gear 24 in theplanetary gearing 18, the overall height remains low despite the integratedmultiple disk brake 29. Mounting of therotating arm 17 is effected byroller bearings 30 arranged coaxially relative to thedrive shaft 28 between rotating internally gearedwheel 27 andstationary web 25. - FIG. 4 differs from the example shown in FIG. 3 in that the internally geared
wheel 31 forms the stationary member firmly linked to thehydraulic motor 32 and thesupport frame 33, while output proceeds via the rotatably mountedweb 35 firmly attached to therotating arm 34. Inaddition, no multiple disk brake is provided. - Installation of the
drive 16 according to FIGS. 2 and 3 is most clearly visible from FIGS. 5 and 6. Thehydraulic motor 21 is placed directly on thehousing 36 of theplanetary gearbox 18 and forms a modular unit therewith, which is rigidly attached to thesupport frame 23. Thegearbox housing 36 of theplanetary gearbox 18 according to FIG. 3 has aring flange 37 which is firmly screwed to the built-onconsole 22. The built-onconsole 22 is welded to the support tube end 38 of thesupport frame 23. Therotating arm 17 is also made of tube and carries a built-onconsole 20 in mirror-image arrangement. The built-onconsole 20 is firmly screwed to aring flange 39 of the internally gearedwheel 27. During assembly, the modular unit is initially screwed to theframe 23. Then therotating arm 17 is screwed to the internally gearedwheel 27, so that therotating arm 17 is rotatable about thevertical rotation axis 19 with the internally gearedwheel 27. Installation of the drive of therotating arm 34 according to FIG. 4 takes place in similar manner, although the lower built-on console is attached to therotating arm 34 not as a mirror-image of the upper built-on console, but identically to the upper built-on console. - In the example according to FIG. 7, the drive of the
rotating arm 40 comprises ahydraulic motor 42 arranged in thesupport frame 41 with a flange-mountedangular gear 43, whosedrive shaft 44 is attached non-rotatably to therotating arm 40. - The example of an alternative rotating arm drive shown in FIG. 8 includes a
hydraulic torque motor 45 or an electric motor, which is arranged upright in thesupport frame 46 withdrive shaft 49 arranged coaxially with thedrive axis 47.
