    ROLLER FOR WRAPPING MACHINES FOR FORAGE AND MACHINE PACASTHAT INCLUDES SUCH ROLLER Technical sector
    The present invention is related to the machines that are used to wrap the cylindrical forage bales with a protective plastic sheet, proposing a roller of
    10 those that are incorporated in said machines to support and rotate the bales of fodder during the wrapping operation thereof, with an embodiment of this roller that allows an effective rotary drive thereof with an advantageously economical transmission. 15 State of the art
    The collection of harvested forage collection is usually done in pressed agglomerations, forming what are called bales or bales, of which one usual form is usually in the form of cylindrical blocks, in which a large amount is accumulated
    20 of fodder, facilitating transport and storage.
    The adequate preservation of the forages during the time they have to be packed requires, however, a waterproof and waterproof protection of the bales, which is carried out conventionally by means of a wrapping covering with a sheet
    25 plastic
    For the wrapping operation of the cylindrical bales there are machines that allow this function to be performed automatically, such as that described, for example, in document ES 2101662, of the same holder as the present invention. The machine is provided with a
    30 pairs of parallel rollers, by means of which the forage bales are supported and rotated during the wrapping action, each of the rollers being provided with a rotating drive.
    In a known embodiment, the rotary drive means of said rollers of the 35 wrapping machines of the cylindrical bale bales is established by means of a motor from which a spline shaft gears with a reciprocated striatum carved inside an axial hollow of an disc that is integral with a rotating tubular sleeve of the roller; This solution is expensive, due to the costly implementation of the disc, which must be tailored precisely and to be replaced, in case of deterioration of the striatum
    5 gear with the motor shaft, requires very difficult operation.
    An alternative solution of lower cost and simple embodiment is therefore necessary that does not require the use of a disc with a specific carving for the gearing of the axis of the drive motor of the roller. Object of the invention
    In accordance with the present invention, a roller for forage bale wrapping machines is proposed, with constructive characteristics that make it advantageous to
    15 rotating transmission of the roller in the wrapping machines, improving the conditions of assembly and economic cost of conventional embodiments. The subject of the present invention is also a forage bale wrapping machine that incorporates the roller.
    The roller object of the invention comprises a support shaft, by means of which the holding of the roller in the wrapping machine is established, a rotating sleeve which is held in free rotation with respect to the support axis by means of bearings, going around said support axis. with a rotary drive transmission that is driven by a motor incorporated in a mounting bracket on the support shaft.
    According to the invention, the transmission of rotation between the support shaft and the roller sleeve comprises two rings that are connected to each other frontally by screws, a chain that is fastened in assembly by means of bolts that fit in the rings and in between which meshes a pinion that is mounted on the output shaft of the motor
    30 drive
    A roller with an effective transmission for the rotating drive of the jacket on the support of the forage bales for its wrapping in the machines of this function is thus obtained, all the elements of the transmission being of a simple construction and, therefore,
    35 both economical, since they do not require precision carving.
    And, on the other hand, the assembly of the transmission, as well as the disassembly, are easy to perform, since the joints between the component elements and the mounting bracket on the roller, are by means of screws.
    5 However, an embodiment is provided in which the transmission of the rotary driveIt is complemented by an additional annular element that is fastened in turn by screwson the transmission rings, with respect to which additional annular element joinssolidarity the roller sleeve, by welding or similar means, thus forming thetransmission a set that allows to establish a firm hold of the roller sleeve,
    10 but at the same time it maintains the conditions of ease of assembly and disassembly of the transmission.
    Therefore, the roller of the invention results in characteristics that make it advantageous and give it preferential character with respect to the conventions rollers of the same application in forage bale wrapping machines. Description of the figures

    The object of the invention relates to a roller for machines for wrapping cylindrical forage bales with a protective plastic sheet, in which machines are conventionally arranged, as shown in Figure 1, two parallel rollers (1) incorporated in respective rocker supports (2) that can be operated, to approximate and separate
    10 the rollers (1), by means of a transverse cylinder (3), for loading and unloading the bales to be wrapped, each of the rollers (1) having a rotating drive for the action of wrapping the bales.
    Conventionally each roller (1) comprises an outer jacket (4), designed so that
    15 on it support the bales to be wrapped, going inside a support shaft (5), by which the mounting bracket of the roller (1) is established on the corresponding support (2) on the wrapping machine, disposing between the jacket (4) and support shaft (5) a transmission
    (6) which is driven by a motor (7), to rotate the jacket (4) in the bale wrap operation.
    The end of the support shaft (5) is fastened by means of a screw (8) on a disk (9) that is fixedly joined to the sleeve (4) by welding or any other similar means, being incorporated between said disk (9) and the support shaft (5) a bearing (10); while in the opposite extreme part it is joined in solidarity with the support shaft (5) another
    25 disc (11), in which the transmission drive motor (7) is moored (6), as well as bearings (12), by means of which, in turn, a rotation coupling of the transmission (6) with respect to the support shaft (5).
    According to the object of the invention, the transmission (6) comprises two rings (13 and 14), the
    30 which are connected to each other frontally and are joined by screws (15) that establish a clamp between them, incorporating between said rings (13 and 14) a chain (16), of which bolts protrude on the side fronts ( 17) that fit in holes
    (18) of the rings (13 and 14), thus being said chain (16) in a clamping assembly
    solidarity with the aforementioned rings (13 and 14). 35 The sleeve (4) of the roller is arranged in a way that is integral with the transmission assembly (6), while the motor (7) is held in a disk (11) integral with the support shaft (5), presenting a splined output shaft (20), in which a pinion is mounted mounted
    (21) that meshes with the chain (16).
    The ring (13) on the back of the transmission (6) has a track on the back
    (22) annular, in which they support the bearings (12) that are incorporated in the disk (11) integral with the support shaft (5).
    10 Thus, when the engine (7) is started, by means of the output shaft
    (20) rotates the pinion (21), which transmits the reduction rotation to the chain (16), rotating the transmission assembly (6) and with it the sleeve (4).
    The realization of the roller results, therefore, from an effective assembly for the drive
    15 of rotation of the jacket (4) for the wrapping of the bales of fodder in the machines of wrapping, being the assembly and disassembly of the transmission (6) very simple to carry out, since only the manipulation of the screws (15).
    An embodiment is envisioned in which the transmission (6) is complemented by an element
    20 additional annular (23), which is arranged on the front of the front ring (14), fastened by screws (19) with respect to the set of rings (13 and 14), to whose additional annular element (23) is attached the jacket (4) in a solidary manner, by welding
    or similar medium. Thus, the assembly of the transmission (6) and the connection of the jacket (4) to the
    Additional annular element (23) can be made independently, which facilitates the assembly and disassembly of the roller component assembly.
