Description

Bale wrapper {BALE WRAPPER}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a bale wrapping machine, and more particularly, to a bale wrapping machine capable of raising a wrapped bale vertically by using a hydraulic cylinder part to vertically lift a wrapped bale.

Livestock farms store rice straw or forage crops for use as feed for livestock during winter, and there has been a problem that the rice straw or forage crops become less fresh over time. Therefore, after harvesting forage crops, a veil packaging machine has been developed which packs a circular veil formed into a baler into a film.

The bale wrapping machine is divided into a roller type and a table type according to a driving method.

The table-type veil wrapping machine is a method in which a separate bobbin driven by a hydraulic cylinder and a circular bale placed on the ground by vertical and horizontal movement of the table are placed on a turntable and wrapped in a plastic film, And the rotating belt rotates the circular bail in the circumferential direction, and at the same time, the wrapping arm attached to the upper frame is wrapped around the bale.

On the other hand, the roller-type bale wrapping machine has a circular bale mounted on a pair of rollers mounted on an arm capable of circumferential movement, and the wrapping arm rotates in a circumferential direction by self-rotation of the two rollers, to be.

The conventional roller-type bale wrapping machine has a problem that the operation time is lengthened because of the slow speed of mounting the veil to the packaging position or discharging the wrapped bale. When a plurality of vinyl films used for packaging are used, There is a problem in that it is troublesome to supply. In addition, when a person or another object collides with the rotating lapping arm during the packaging operation, the lapping arm can not be immediately stopped from driving so that secondary and tertiary collisions occur, posing a risk of a safety accident.

In addition, since the conventional bale packing apparatus discharges the wrapped bale immediately so that the circumferential surface thereof touches the support surface, there is a problem in that it is necessary to separately perform the operation of raising the bale by using the separate equipment in the process of moving to the storage warehouse or stacking there was.

As shown in FIG. 1, in the case of the bale wrapping machine 10 including conventional standing means, in order to stand the bale B, the height H of the ground and the bale B must be at least about 700 mm The veil B is raised. The conventional bale wrapping machine 10 can not lift the bale wrapping machine itself, so that the lower link of the separate tractor has to be lifted as much as possible.

Hereinafter, the shrinkage or expansion state of the hydraulic pressure elevating portion 153, which is changed during the bail discharging process after the bale wrapping operation is completed, will be mainly described.

3 is a front view showing a state where the bail B is loaded in the bale wrapping machine 100 of FIG. 2, and FIG. 4 is a side view illustrating the state where the wrapping operation of FIG. 3 is completed, .

The bail wrapping machine 100 is required to determine whether or not the bail B can be seated according to the spacing distance between the first roller 129 and the second roller 129-1, The distance when the two roller portions 129-1 are adjacent to each other is smaller than the diameter of the bail B to be packed.

When the first roller portion 129 and the second roller portion 129-1 are opened in a direction away from each other, the distance between the first roller portion 129 and the second roller portion 129-1 is greater than the diameter of the bail.

In the process of wrapping the wrapped bale B with the vinyl film, the bale wrapping machine 100 is seated on the ground as shown in FIG. In this case, the hydraulic pressure raising portion 153 of the hydraulic cylinder portion 150 is in the maximum contracted state.

When the bale B is wrapped, the bale B must be discharged. Since the bale wrapping machine 100 is lower than the minimum height at which the bale B can be raised from the ground, the bale wrapping machine 100 ) Should be raised vertically.

At this time, in order to vertically raise the bale packing machine 100 from the ground, as shown in Figs. 5 to 6, pressure is applied to the cylinder of the hydraulic pressure elevator 153 to project the rod inserted in the cylinder.

The hydraulic lifting unit 153 is fixed to the third frame unit 113 via the hydraulic pressure fixing unit 152 to vertically lift the entire bale wrapping machine 100 from the ground. In this case, as shown in FIG. 6, the height H of the bale wrapping machine 100 from the ground is 700 mm or more.

FIG. 7 is a side view showing a state in which the wrapped bail is discharged in FIG. 6; FIG.

The hydraulic lifting unit 153 is retracted again after the bail B is discharged to seat the bale wrapping machine 100 on the ground.

The present invention improves the working efficiency because a separate hydraulic lever operation necessary for raising the bail B to be discharged is unnecessary. Further, since the operation of the hydraulic lever is not required in the process of packaging the bale, it is possible to prevent the failure due to the erroneous operation of the hydraulic lever.
