Description

Technology Field

[0001] The present invention relates to a bale wrapping machine equipped with an automatic loading function, and more specifically, to a bale wrapping machine capable of automatically loading and unloading bales scattered in fields through a detection sensor and an angle sensor. Background Technology

[0003] A bale refers to a bundle of rice straw or wheat straw formed into a cylindrical or box shape for use as roughage for livestock, and a baler refers to an agricultural machine that makes such bales.

[0004] In addition, the bale wrapping machine seals the bales produced by the baler with plastic wrap to prevent partial loss during transportation or stockpiling.

[0005] In addition, if a fermentation accelerator (such as ammonia or NaOH) is added during the sealing process to allow fermentation to occur during storage, the palatability of the roughage is increased, which prevents selective eating of concentrated feed (grains or bran, etc.), and the demand for sealed bales (hereinafter referred to as 'packaged bales') is increasing day by day, especially among high-end Hanwoo cattle farms.

[0006] Typically, these bale wrapping machines are towed by a tractor to traverse fields, loading scattered bales and sealing them. Once unloaded back onto the fields, a tractor equipped with a grapple collects them and stacks them in one place or loads them onto a transport vehicle.

[0007] In addition, as described in Patent Document 1 (see FIG. 1), a general wrapping machine performs a sealing operation in which a rotating arm (32') rotates around a bale while the bale is rotated by a seating table (21') and wraps a vinyl wrap (34'), and the seating table (21') is provided to be tilted backward by a hydraulic cylinder (13').

[0008] However, in conventional wrapping machines, since the operator performs the loading operation while visually checking the arrangement of the wrapping machine and the bale as the tractor approaches the bale's location, work efficiency is heavily dependent on the operator's skill level.

[0009] In addition, if bales are loaded unstably and packaging defects occur, the deformation of the bales' exteriors can make outdoor stacking unstable, potentially leading to safety accidents. In particular, incomplete sealing can cause a decrease in the shelf life of forage and lead to poor fermentation. Prior art literature

The sensing sensor transmits to the control unit when the bale approaches an appropriate distance suitable for loading through the retraction of the bale wrapping machine, and the control unit operates the loading arm to grasp the bale and rotates the frame to make the support bar and the roller unit horizontal, thereby automatically completing the loading operation.

[0015] In addition, the bale wrapping machine having an automatic loading function according to the present invention is characterized by further including a first angle sensor, which is provided on the frame hinge axis to measure the rising and lowering angles of the frame and transmit them to the control unit, and a second angle sensor, which is provided on the hinge axis of the loading arm to measure the rising and lowering angles of the loading arm and transmit them to the control unit.

Effects of the invention

[0020] According to the bale wrapping machine equipped with an automatic loading function of the present invention, bales scattered in fields can be automatically loaded through a detection sensor provided on a support bar, thereby improving the efficiency of the bale wrapping operation.

Specific details for implementing the invention

[0025] Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the attached drawings.

[0027] Referring to FIG. 2 and FIG. 3, a bale wrapping machine with an automatic loading function according to an embodiment of the present invention comprises a packaging unit (10) that performs a bale sealing operation with vinyl wrap, a rotating unit (20) that is positioned below the packaging unit (10) and rolls the bale for the sealing operation, a sensing unit (30) that performs a sensing operation necessary to load the bale onto the rotating unit (20), and a control unit (not shown) that is provided in the driver's seat of a tractor and manages the operation of the auxiliary device of the above configuration.

[0029] Hereinafter, the specific details of the present invention will be explained focusing on the above components. First, the packaging unit (10) includes a pair of rotating arms (11) and a vinyl wrap holder (12) provided at the end of each rotating arm (11). During the rotation of the rotating arms (11), the vinyl wrap of the holder (12) unfolds to wrap and seal the bale being rolled in the rotating unit (20).

[0030] Other detailed configurations conform to the prior art.

[0032] The rotating part (20) includes a pair of rotatably configured frames (21), a support bar (22) and a roller unit (23) configured between the frames (21), and a loading arm (24) configured rotatably configured at one end of the frames (21).

[0033] For loading operations, the frame (21) is rotatably provided via a hydraulic cylinder or a drive motor, and the loading arm (24) is deployed to grasp one side of the bale during loading.

[0034] And the roller unit (23) includes one driving roller (231) and a plurality of driven rollers (232), and when a bale is placed on the upper part of the roller unit (23) during a loading operation, the driving roller (231) is activated and rolling of the bale is initiated.

[0036] The sensing unit (30) includes a sensing sensor (31) positioned at the center of the support bar (22), a first angle sensor (32) for controlling the rotation angle of the frame (21), and a second angle sensor (33) for controlling the rotation angle of the loading arm (24).

[0037] The above detection sensor (31) transmits this to the control unit when the bale approaches a suitable distance for loading as the bale wrapping machine moves backward, and the control unit operates the loading arm (24) to automatically perform the loading operation.

[0038] The automatic loading process of such a bale is illustrated in Fig. 4.

[0039] First, when the bale wrapping machine is towed by a tractor to move to a field, the rotating part (20) moves in a horizontal state as shown in FIG. 2, and then when it arrives at the field, the operator rotates the frame (21) to set up the support bar (22) and roller unit (23) and lifts the loading arm (24) to prepare for work.

[0040] After that, the reverse direction (x) of the wrapping machine is aligned with the bale placement direction (x') to achieve the state as shown in FIG. 4 (a), and when the bale approaches a suitable distance for loading as shown in FIG. 4 (b), the detection sensor (31) transmits this to the control unit to lower the loading arm (24) to grasp the bale as shown in FIG. 4 (c), and as shown in FIG. 4 (d), the frame (21) is rotated to make the support bar (22) and the roller unit (23) horizontal so that the loading operation is completed.

[0042] Meanwhile, when the frame (21) and the loading arm (24) operate at a certain angle, depending on the size, weight, etc. of the bale, the loading operation of the bale may not be completed in one go and may have to be performed repeatedly.

[0043] The above angle sensor (32) is provided on the hinge axis of the frame (21) to measure the rising and falling angles of the frame (21) and transmit them to the control unit, and when the frame (21) reaches a set angle, the operation is stopped by the control unit.

[0044] The above 2-angle sensor (33) is provided on the hinge axis of the loading arm (24) to measure the rising and falling angles of the loading arm (24) and transmit them to the control unit, and when the loading arm (24) reaches a set angle, the operation is stopped by the control unit.

[0045] In this way, the present invention enables stable gripping while considering the condition of the bale (B) by adjusting the rising and falling angles of the frame (21) and the loading arm (24) through the first angle sensor (32) and the second angle sensor (33).

[0047] Meanwhile, in order for the bale to be loaded normally onto the roller unit (23), it is required that the reverse direction (x) of the wrapping machine coincide with the bale placement direction (x') as shown in FIG. 5.

[0048] Here, the statement that the bale is loaded normally onto the roller unit (23) means that the direction of rotation axis (y) of the roller unit (23) and the direction of length (y') of the bale are loaded parallel to each other.

[0049] To this end, the present invention may additionally provide a pair of distance sensors (34) that guide the backward direction (x) of the wrapping machine to be aligned with the bale placement direction (x') prior to loading.

[0050] Each distance sensor (34) is positioned at both ends of the support bar (22) to measure the distances (L1, L2) between both ends of the bale in the longitudinal direction (y') and the bale wrapping machine, respectively, during the bale approach process, and transmit them to the control unit.

[0051] And if the control unit compares the received measurement value and causes the alarm means to sound a different notification sound depending on the rightward bias (L1 < L2) or leftward bias (L1 > L2) of the wrapping machine, the operator can adjust the reverse direction (x) of the wrapping machine according to the notification sound to approach the bale in a state without bias (L1 = L2), thereby enabling normal loading, and thus the problems caused by packaging defects as described above can be resolved.

[0052] Meanwhile, the detection sensor (31) is provided with a capacitive proximity sensor, and the distance sensor (34) is recommended to be a laser sensor with excellent responsiveness, but is not limited thereto.

[0054] The control unit is typically located in the driver's seat of the tractor and performs control operations to automatically execute bale loading, wrapping, and unloading.

[0055] That is, when a signal is received from the detection sensor (31) that the bale wrapping machine has approached the bale at an appropriate distance suitable for loading, the loading operation of the bale is automatically started, and when the loading operation is completed, a wrapping operation including sealing and cutting operations is automatically performed, and when the wrapping operation is completed, the packaging bale is automatically unloaded after a predetermined time has elapsed. This series of processes is controlled sequentially.

[0056] And the above task is automatically performed repeatedly for each veil.

[0058] Although preferred embodiments of the present invention have been described above, the scope of the present invention is not limited thereto and should be understood to extend to those within a scope substantially equivalent to the embodiments of the present invention. Various modifications can be made by those skilled in the art to which the present invention belongs, without departing from the technical spirit of the present invention. Explanation of the symbols
