In the first embodiment, since the bottom surface R7 of the roll bale R has multiple layers of wrap films and is thicker than the peripheral surface R6 of the columnar roll bale R, the roll bale R is placed vertically and protrusions such as the residual trunk are stuck. This is one aspect of reducing the probability of holes being formed in the wrap film.
FIG. 1 is a perspective view (A), a side view (B), and a rear view (C) showing the entire lapping device 1 according to the first embodiment.
On the side of the wrapping device 1, a wrap film wrapping device 7 including a stretch roller 71 for applying tension to the wrap film and a wrap film mounting table 72 for supporting and fixing the wrap film is provided.

As shown in FIG. 1A, the vertical arm 5 is provided at the rear end 25 of the roll bale support machine base 2 provided with the roll bale support 21. Then, the vertical arm 5 is attached so as to fit along the end surface 24 (the side where the roll bale R is loaded and unloaded) of the rear end 25 of the roll bale bearing machine base 2 (dotted line in FIG. 1 (A)). Refer to the vertical arm 5 shown in (1). The end face 24 is a virtual surface as shown by the alternate long and short dash line.
The vertical arm 5 has a vertical arm rotation shaft in a direction in which the vertical arm 5 stands up with respect to the roll bale support machine base 2 from a state along the end face 24 (shown by a chain line) as shown by an arrow in FIG. 1 (A). A vertical arm driving unit 51 that rotatably drives the 52 is provided.
When the roll bale R is loaded and unloaded, the vertical arm 5 is rotated by the vertical arm driving unit 51 in a direction in which it stands up with respect to the roll bale bearing unit 2 as shown by the solid line.
In the first embodiment, the vertical arm 5 is the rear end 25 of the roll bale support machine base 2 and is provided close to either the left or right side.

A loading / unloading arm 4 for gripping the peripheral surface R6 of the roll bale R is provided when loading / unloading the roll bale R before wrapping and when loading / unloading the roll bale R after wrapping. As can be seen from FIG. 1B, the loading / unloading arm 4 is provided on the roll bale bearing machine base 2. The loading / unloading arm 4 is configured to be rotatably driven with respect to the roll bale bearing machine base 2 by the loading / unloading arm driving unit 41 composed of a hydraulic cylinder. Further, the loading / unloading arm 4 is adapted to rotate to a position where the winding is not hindered when the wrap film is wound.

As can be seen from FIGS. 1B and 1C, a roll bale bearing machine base 2 is provided on the wrapping device machine frame 11, and the roll bale R before wrapping is placed when the wrap film is wound. The roll bale support portion 21 is provided on the roll bale support unit machine base 2.

As shown in FIG. 1 (B), the roll bale bearing machine base 2 has a tilting shaft 22 provided on the wrapping device machine frame 11, and the tilting shaft 22 is provided when the roll bale R is loaded and unloaded. A tilting drive unit 23 for tilting the roll bale bearing unit 2 is provided at the center.

The lapping device machine frame 11 is provided with a wrap film wrapping device 7. Further, as shown in FIG. 1B, a vertical control unit 6 is provided. As described above, the installation position of the vertical control unit 6 is not limited to the installation position of the first embodiment.

(Roll bale loading process)
As described above, the roll bale bearing machine base 2 is configured to tilt backward about the tilting shaft 22 shown in FIG. 1 (B).
FIG. 2 is a perspective view of the roll bale support unit 2 of the wrapping device 1 according to the first embodiment in an upright state, and rolls the peripheral surface R6 of the roll bale R before wrapping, which is placed in a state of being laid down in the field. The wrapping device 1 is operated so as to come into contact with the bale support portion 21.
Further, a roller 211 is provided at the end of the roll bale support machine base 2 when viewed from the back surface, which is useful as an aid when loading the roll bale R before wrapping. It also helps prevent the wrapped roll bale R wrap film from being damaged during vertical placement.

FIG. 3 is a rear view of the roll bale R of the wrapping device 1 according to the first embodiment at the start of loading, FIG. 3 (A) is a rear view before the start of loading, and FIG. 3 (B) is a rear view at the start of loading. Is.
As shown in FIG. 3A, when the roll bale R before wrapping, which is placed in the field in a collapsed state, approaches or comes into contact with the roll bale bearing portion 21 (which is on the back surface of the roll bale R and is not shown). , As shown in FIG. 3B, the loading / unloading arm 4 is driven downward to firmly hold the roll bale R before wrapping.

FIG. 4 is a side view of the lapping device 1 according to the first embodiment when the loading of the roll bale R is completed.
The roll bale support machine base 2 has a tilting shaft 22 provided on the lapping device machine frame 11, and is configured to tilt freely so as to fit on the lapping device machine frame 11. By rotating the roll bale bearing machine base 2 so that it fits on the wrapping device machine frame 11, the roll bale R before wrapping held between the roll bale bearing 21 and the loading / unloading arm 4 , Loaded on the wrapping device 1.
During the loading operation of the wrapping device 1, the vertical arm 5 is tilted along the end surface 24 of the roll bale support machine base 2 (the position of the vertical arm 5 shown by the dotted line in FIG. 1A). Please refer to.).

(Wrapping process)
Since the configuration and operation of the roll bale support portion 21 and the wrap film wrapping device 7 are well known, only a brief description will be given.
The roll bale bearing 21 rotates horizontally on the roll bale bearing machine base 2 at the time of wrapping. The roll bale R before wrapping is placed so that its peripheral surface R6 is wrapped in a belt provided on the roll bale support portion 21, and is gradually rotated around the peripheral surface R6 to form a wrap film winding device 7. The entire surface is wrapped by a wrap film stretched between the roll bale R and the roll bale R.

(Roll bale loading and unloading process)
When loading and unloading the roll bale R, as shown in FIG. 1 (A), the vertical arm driving unit 51 is housed along the end surface 24 of the rear end 25 of the roll bale bearing machine base 2 shown by the dotted line. The vertical arm 5 is rotated in a standing direction with respect to the roll bale bearing machine base 2.
5A and 5B are side views showing a loading and unloading process of the roll bale R of the wrapping device 1 according to the first embodiment, FIG. 5A is a side view at the start of loading and unloading, and FIG. 5B is a side view during loading and unloading. FIG. 5 (C) is a side view when the roll bale R is lowered in the field.
At the start of loading and unloading, as shown in FIG. 5A, the loading and unloading arm 4 holds the roll bale R. Then, the vertical arm 5 is controlled by the vertical control unit 6 so as to rotate in a rising direction with respect to the roll bale bearing unit 2 as described above.

As shown in FIG. 5B, the roll bale support machine base 2 gradually tilts about the tilting shaft 22 and moves away from the lapping device machine frame 11. As shown in FIG. 5C, the vertical control unit 6 controls the tilt of the roll bale support unit 2 until the columnar roll bale R finally touches the ground in a state of being laid down on the field. .. Finally, the vertical arm 5 attached to the rear end 25 of the roll bale support machine base 2 moves with the roll bale support machine base 2 tilting until it touches the ground.

Although the aspect controlled by the vertical control unit 6 has been described above, the present invention also includes an aspect in which the roll bale R may be manually loaded and unloaded, and the vertical control unit 6 is not provided.

(Vertical installation process of roll bale)
When the roll bale support machine base 2 is sufficiently tilted, the roll bale R comes into contact with the ground while lying down on the field. At this time, the vertical arm 5 is sandwiched between the field and the roll bale R (see FIG. 5C). As shown in FIG. 1 (A), the vertical arm 5 is in an upright position (solid line position), so that when viewed from the roll bale R, it is displaced to one end side of the fallen roll bale R. The vertical arm 5 is in contact with the peripheral surface R6 of the roll bale R.
Next, the loading / unloading arm 4 is controlled by the vertical control unit 6 so as to be separated from the roll bale R.

FIG. 6A is a rear view of the roll bale R at the start of the vertical installation process, and FIG. 6B is a side view of the roll bale R at the start of the vertical installation process.
As shown in FIGS. 6 (A) and 6 (B), the loading / unloading arm 4 is rotated to a position separated from the roll bale R, and in this state, the roll bale bearing machine base 2 is tilted. With the shaft 22 as a fulcrum, tilting is started in a direction that fits in the wrapping device machine frame 11. The movement of the roll bale support unit 2 is the same as the loading process of the roll bale R.
When the roll bale bearing machine base 2 starts tilting, the vertical arm 5 attached to the roll bale bearing machine base 2 rises. As described above, since the vertical arm 5 is displaced to one end side of the roll bale R and is in contact with the peripheral surface R6 of the roll bale R, the one end side of the roll bale R gradually starts to be lifted, and the roll bale R finally starts to be lifted. It is placed vertically.

In the vertical installation process, the roll bale R and the vertical arm 5 come into contact with each other, and the vertical arm 5 slides on the peripheral surface R6 of the roll bale R as it rises. The wrap film was sometimes damaged. As shown in FIG. 6C, the vertical arm 5 of the first embodiment has a structure in which a columnar exterior material 55 is covered around a columnar core material 54, and is a cylindrical exterior material. In the 55, the cylindrical exterior material 55 of the vertical arm 5, which is configured to freely rotate around the core material 54, freely rotates, so that the wrap film wound around the roll bale R is damaged. There is no such thing.
The movement of each member of the wrapping device 1 in the series of vertical roll bale steps is also controlled by the vertical control unit 6 in the first embodiment, but it may be manually moved, and the vertical control unit 6 is provided. Aspects that do not exist are also included in the present invention.

(Summary of Example 1)
The drive source when the vertical arm 5 lifts the roll bale R in a tilted state is a tilt drive unit 23 that tilts the roll bale support machine base 2, and a separate drive source is used to lift the roll bale R. The structure of the wrapping device 1 can be simplified without the need to provide it.
Further, the vertical installation of the roll bale R can be performed by a simple movement of grounding the roll bale R on the vertical arm 5 and then lifting the roll bale bearing machine base 2 that supports the vertical arm 5. This makes it possible to improve the efficiency of the vertical installation work of the roll bale R.
Further, since the bottom surface R7 of the roll bale R has multiple layers of wrap films and is thicker than the peripheral surface R6 of the columnar roll bale R, it is possible to reduce the probability that protrusions such as the residual trunk will stick and holes will be formed in the wrap film. ..

<Example 2>
Each member provided in the lapping device 1 is the same as in the first embodiment. Further, the movement of each member of the wrapping device 1 up to the loading / unloading step is the same as that of the first embodiment.

(Vertical installation process of roll bale)
The field on which the roll bale R is to be placed vertically may be inclined so that the side on which the roll bale R is loaded or unloaded is lowered. In such a case, if the loading / unloading arm 4 is separated from the roll bale R, it may roll due to the inclination of the field and the roll bale R may be separated from the wrapping device 1. Further, even in a flat field, if the roll bale R is light or the like, the roll bale R may be separated from the wrapping device 1 as the loading / unloading arm 4 is separated.
Further, in a field where the roll bale R is inclined so as to be lowered in the vertical direction, the roll bale R placed vertically may fall over and fall down.

Therefore, in the second embodiment, the loading / unloading arm 4 moves so as to support the roll bale R to the extent that the vertical placement is not hindered without being separated from the roll bale R during the vertical placement process of the roll bale R. The loading / unloading arm drive unit 41 is controlled by the vertical control unit 6. FIG. 7 is an explanatory view of a vertical installation step of the roll bale R according to the second embodiment, which is a perspective view of FIG. 7A and a rear view of FIG. 7B. As shown in FIGS. 7 (A) and 7 (B), the roll bale R is a time when the roll bale R is supported by the loading / unloading arm 4 to the extent that the vertical placement is not hindered, and the roll bale R covers the field. Avoid rolling. When the roll bale support machine base 2 starts tilting, the vertical arm 5 attached to the support machine base 2 also rises, and gradually starts to lift one end side of the roll bale R. Since the loading / unloading arm 4 is controlled by the vertical control unit 6 so as to support the roll bale R to the extent that the vertical placement is not hindered, the field is tilted so that the direction in which the roll bale R is vertically placed is lowered. Even if it is, the roll bale R is quietly placed vertically and does not tip over.
It should be noted that the loading / unloading arm drive unit 41 may be manually operated without being controlled by the vertical control unit 6 as in the first embodiment.
On a slope, the roll bale R may fail to be placed vertically, and the roll bale R may be placed vertically on the failed roll bale R again. However, in the second embodiment, the roll bale R is also placed on a slope. The vertical installation of the roll bale R is less likely to fail, and the efficiency of the vertical installation work of the roll bale R can be achieved.
Further, since the bottom surface R7 of the thick roll bale R with multiple overlapping wrap films is placed downward and quietly vertically, the probability that a protrusion such as a stump sticks and a hole is formed in the wrap film can be reduced. Further, when the vertical placement is unsuccessful, a protrusion such as a residual trunk may pierce the peripheral surface R6 of the roll bale R in which the overlap of the wrap film is thin, and a hole may be formed in the wrap film. In the second embodiment, since the loading / unloading arm 4 is controlled by the vertical installation control unit 6 so as to support the roll bale R to the extent that the vertical installation is not hindered, a hole is formed in the wrap film due to the failure of the vertical installation. You can reduce the probability of opening.

<Example 3>
Each member provided in the lapping device 1 is the same as in the first embodiment. Further, the movement of each member of the wrapping device 1 up to the wrapping step is the same as that of the first embodiment.

(Vertical installation process of roll bale)
When the roll bale R is placed vertically, as shown in FIG. 1 (A), the vertical arm 5 is accommodated along the end surface 24 of the rear end 25 of the roll bale support machine base 2 shown by the dotted line. , The vertical arm drive unit 51 rotates in the direction of standing up with respect to the roll bale support unit machine base 2.
8A and 8B are explanatory views of a vertical installation process of the roll bale R according to the third embodiment, FIG. 8A is a side view at the start of discharge, and FIG. It is a side view when the roll bale R is released.
In the third embodiment, at the start of discharging the roll bale R, the vertical control unit 6 keeps the loading / unloading arm 4 separated from the roll bale R as shown in FIG. 8 (A), and keeps the roll bale support portion. The machine base 2 is controlled to be tilted.
With the momentum that the roll bale R is released and dropped from the tilting roll bale support machine base 2, the peripheral surface R6 end of the roll bale R hits the vertical arm 5, and the roll bale R is vertically placed.

The field where the roll bale R is to be placed vertically is inclined so that the side where the roll bale R is loaded and unloaded is lowered, and the momentum of the release and falling increases, so that the roll bale R may not be placed vertically. In such a case, the roll bale bearing portion is determined by the tilt angle of the field or the wrapping device 1 detected by the tilt angle detector 8 provided in the wrapping device 1 shown in FIGS. 8 (A) and 8 (B). The vertical control unit 6 may control the tilting speed of the machine base 2.
On the contrary, in the field where the roll bale R is to be placed vertically, the side where the roll bale R is loaded and unloaded is inclined upward, and the momentum of the release and falling is weak, so that the roll bale R may not be placed vertically. In such a case, the vertical control unit 6 may control the tilting speed of the roll bale bearing unit 2 according to the tilt angle detected by the tilt angle detector 8.
It should be noted that the loading / unloading arm 4 may be manually performed without providing the vertical control unit 6 and the tilt angle detector 8 and without controlling it, as in the first embodiment.

On a slope, the roll bale R may fail to be placed vertically, and the roll bale R may be placed vertically on the failed roll bale R again. In Example 3, the roll bale R was also placed on a slope. The vertical installation of the roll bale R is less likely to fail, and the efficiency of the vertical installation work of the roll bale R can be achieved.
When the vertical placement was unsuccessful, protrusions such as a residual trunk pierced the peripheral surface R6 of the roll bale R in which the overlap of the wrap film was thin, and a hole was sometimes formed in the wrap film. In the third embodiment, the vertical placement is less likely to fail, and the failure in the vertical placement can reduce the probability of holes being formed in the wrap film.

<Example 4>
Each member provided in the lapping device 1 is the same as in the first embodiment. Further, the movement of each member of the wrapping device 1 up to the wrapping step is the same as that of the first embodiment.

(Vertical installation process of roll bale)
9A and 9B are explanatory views of a vertical installation step of the roll bale R according to the fourth embodiment, FIG. 9A is a side view at the start of discharge of the roll bale R, and this state is shown in FIG. 1A. As shown, the vertical arm driving unit 51 stands up from the roll bale support machine base 2 shown by the dotted line in the vertical direction with respect to the roll bale support machine base 2. It shows the state of being rotated by.
Further, the loading / unloading arm 4 is rotated by the loading / unloading arm driving unit 41 so as to hold the peripheral surface R6 of the roll bale R.

Next, while the roll bale R is held by the roll bale support portion 21 and the loading / unloading arm 4, the roll bale support unit 2 is tilted from the wrapping device machine frame 11 around the tilt shaft 22. Then, when the roll bale support machine base 2 reaches a predetermined tilt angle as shown in FIG. 9B, the roll bale support machine base 2 is stopped from tilting, and the loading / unloading arm 4 is separated from the roll bale R. The vertical control unit 6 controls the roll bale R so as to release the roll bale R.
The peripheral surface R6 end of the roll bale R that has been released and dropped hits the vertical bar 5, and the roll bale R is placed vertically.
When the roll bale support unit 2 is stopped from tilting when the roll bale R loading / unloading side is tilted so as to be lowered, or conversely when the roll bale R loading / unloading side is tilted so as to be raised. By adjusting the inclination angle of the roll bale R, the momentum of the release and falling of the released roll bale R can be changed, and the roll bale R can be reliably placed vertically according to the inclination of the field.
The vertical control unit 6 controls the tilt angle at which the roll bale bearing machine base 2 is stopped from tilting according to the tilt angle of the field or the wrapping device detected by the tilt angle detector 8 provided in the wrapping device 1. May be good.
It should be noted that the loading / unloading arm 4 may be manually performed without providing the vertical control unit 6 and the tilt angle detector 8 and without controlling it, as in the first embodiment.

In the fourth embodiment, the momentum of the release and falling of the released roll bale R can be changed, the roll bale R can be reliably placed vertically according to the inclination of the field, and the roll bale R can be placed vertically. Efficiency can be achieved.
When the vertical placement was unsuccessful, protrusions such as a residual trunk pierced the peripheral surface R6 of the roll bale R in which the overlap of the wrap film was thin, and a hole was sometimes formed in the wrap film. In the third embodiment, the vertical placement is less likely to fail, and the failure in the vertical placement can reduce the probability of holes being formed in the wrap film.

<Example 5>
Each member provided in the lapping device 1 is the same as in the first embodiment.
As shown by the dotted line in FIG. 1A, the vertical arm 5 is attached so as to fit along the end surface 24 of the rear end 25 on the side where the roll bale R of the roll bale support machine base 2 is to be loaded and unloaded. .. As shown in FIG. 1 (A), the vertical arm 5 is accommodated along the end surface 24 of the roll bale bearing machine base 2 with the vertical arm rotation shaft 52 as the center, and the roll bale bearing machine It rotates in the direction of standing up with respect to the table 2.
In the step of loading and unloading the roll bale R as described above, the vertical arm 5 becomes horizontal as shown in FIGS. 5 (A) to 5 (C).

The case where the roll bale R is a horizontal field will be described first.
In the following, the intermediate line R2 refers to a line drawn around the circumference of the cylinder at the intermediate point in the height direction of the vertically placed roll bale R (cylindrical) (see FIG. 10 (Ab)). ). (Note that the "intermediate line R2" serves as a reference in the case of a horizontal field, but the center of gravity R5 will be taken into consideration in a sloping field as described later.)
FIG. 10 is an explanatory view according to the fifth embodiment, and FIG. 10A is a wrapping when the vertical arm 5 is tilted to the right of the intermediate line R2 of the roll bale R and the roll bale R is grounded. It is a rear view of the apparatus 1. Further, FIG. 10B is a rear view of the wrapping device 1 when the vertical arm 5 is tilted to the left of the intermediate line R2 of the roll bale R and the roll bale R is grounded.
As shown in FIGS. 10A and 10B, even if the vertical arm 5 is tilted to the right of the intermediate line R2 of the roll bale R, the vertical arm 5 is tilted to the right of the roll bale. The position of the vertical arm base 56 provided with the vertical arm rotation shaft 52 does not change even if the vertical arm rotation shaft 52 is tilted to the left of the intermediate line R2.
However, as shown in FIGS. 10 (Ab) and 10 (B), the position of the vertical arm 5 as seen from the ground plane is such that the vertical arm 5 is positioned as shown in FIG. 10 (Ab). It is different when the vertical arm 5 is tilted to the right of the middle line R2 of the roll bale R and when it is tilted to the left of the middle line R2 of the roll bale R as shown in FIG. 10 (B-b). Come on.

The roll bale R is columnar, and when the roll bale R is unloaded in the present invention, the roll bale R is unloaded so that the central axis of the collapsed columnar roll bale R is horizontal. At this time, the portion where the roll bale R touches the ground becomes a line shape as shown by the grounding line R1. However, since the roll bale R is soft and slightly crushed by its own weight, it becomes a wide line even if it is in the shape of a line.
The tip 53 of the vertical arm crosses the grounding line R1, and the intersection R4 of the vertical arm 5 and the grounding line R1 does not cross the intermediate line R2 of the roll bale R, and is on the right side of the intermediate line R2. In this case, the vertical arm 5 is tilted to the right of the intermediate line R2 in FIG. 10 (Ab).
On the other hand, when the tip portion 53 of the vertical arm crosses the grounding line R1 and the intersection R4 of the vertical arm 5 and the grounding line R1 crosses the intermediate line R2 of the roll bale R and is on the left side of the intermediate line R2. However, the vertical arm 5 is tilted to the right of the intermediate line R2 in FIG. 10 (Bb).
The perspective views are as shown in FIGS. 10 (A-c) and 10 (B-c), respectively.

10 (A-c) and 10 (B-c) show that the fallen columnar roll bale R and the vertical arm 5 come into contact with each other only at one point R4 at the intersection with the grounding line R1. You can see from.
In this state, when the process proceeds to the above (vertical installation step of the roll bale), the vertical arm 5 attached to the roll bale support machine base 2 starts to be lifted. As shown in FIGS. 10 (Ab) and 10 (A-c), if there is a vertical arm 5 shifted to the right of the intermediate line R2, the vertical arm 5 will be at the intersection R4 (intermediate line) of the ground line R1. Since it comes into contact with the roll bale R only (on the right side of R2), it starts to lift the columnar roll bale R that has fallen from this intersection R4. Then, the collapsed columnar roll bale R stands up with the rotation fulcrum R3 at the left end of the collapsed columnar roll bale R shown in FIG. 10 (Ac) as a fulcrum. In this case, the roll bale R is vertically placed on the left side when viewed from the back surface of the lapping device 1. FIG. 11 is a perspective view showing a vertical installation position seen from the back surface of the wrapping device 1 according to the fifth embodiment, and is a wrapping device 1 as shown in the “vertical installation position in the case of FIG. 10 (Ac)” shown here. The roll bale R is placed vertically on the left side of.

If the tip 53 of the vertical arm does not cross the ground line R1, the vertical arm 5 is not in contact with the fallen columnar roll bale R. When the vertical arm 5 is lifted together with the roll bale support machine base 2, the vertical arm tip 53 simply moves so as to trace the columnar peripheral surface R6 of the collapsed columnar roll bale R, and the roll bale R Cannot be lifted and placed vertically. Therefore, the vertical arm 5 needs to have a length such that the tip 53 of the vertical arm can cross the grounding line R1.

Similarly, as shown in FIGS. 10B and 10B, if there is a vertical arm 5 shifted to the left from the intermediate line R2, the vertical arm 5 will be at the intersection R4 of the grounding line R1. Since it comes into contact with the roll bale R only (on the left side of the intermediate line R2), it starts to lift the columnar roll bale R that has fallen from this intersection R4. The collapsed columnar roll bale R stands up with the rotation fulcrum R3 at the right end of the collapsed columnar roll bale R illustrated in FIG. 10 (BC) as a fulcrum. The roll bale R is vertically placed on the right side of the wrapping device 1 as shown in the “vertical position in the case of FIG. 10 (BC)” shown in FIG.

(In the case of a slope that slopes to the left and right when viewed from the back of the lapping device)
The above explanation is for the case where the field is horizontal.
In the case of a slope that slopes to the left or right when viewed from the back of the wrapping device 1, it is easy to place it vertically on the down side, but it may not be possible to place it vertically on the up side even if the vertical arm 5 is tilted. .. FIG. 12 is an explanatory view of the slope of the fifth embodiment.
On flat ground, the middle line R2 passed through the center of gravity R5 of the roll bale R, so the right and left halves of the fallen roll bale R have the same weight, and the vertical arm 5 is placed to the right of the middle line R2. It was possible to place it vertically on the right and left as shown in FIG. 11 by changing whether it was moved to the left or the left. However, on a slope that slopes to the left or right, it is necessary to move the vertical arm 5 in consideration of the center of gravity R5.
That is, when viewed from the back surface of the wrapping device 1, it depends on whether the vertical arm tip 53 sufficiently exceeds the grounding line R1 and is to the right or left of the intersection R4 between the vertical line lowered from the center of gravity R5 and the grounding line R1. , Whether the roll veil R is placed vertically on the right or vertically on the left changes.
When the vertical arm tip 53 is to the right of the intersection 4, the roll bale R is placed vertically to the left, and when the vertical arm tip 53 is to the left of the intersection 4, as shown in FIG. 12, the roll is rolled. The bale R is placed vertically on the right.

FIG. 12 is a perspective view of the roll bale when the vertical arm 5 is tilted to the left in consideration of the center of gravity R5 of the roll bale R. However, when the vertical arm 5 having a short length is adopted, if the vertical arm 5 is greatly moved (the vertical arm 5 is tilted greatly), the vertical arm tip 53 does not cross the grounding line R1. Can occur.
This can be solved by using a long vertical arm 5. However, when the long vertical arm 5 is adopted, the vertical arm 5 may protrude to the side beyond the machine width of the wrapping device 1. In such a case, the vertical arm 5 can be expanded and contracted, the vertical arm 5 can be shortened in normal times, and the vertical arm 5 can be extended when dealing with a slope.

The vertical installation of the roll bale R is a simple movement of grounding the roll bale R on the vertical arm 5 and then lifting the roll bale bearing machine base 2 that supports the vertical arm 5, in either the left or right direction. It can also be installed vertically, and the efficiency of the vertical installation work of the roll bale R can be achieved.

The vertical arm 5 may be provided at the center of the rear end 25 (the side where the roll bale R is loaded / unloaded) of the roll bale bearing machine base 2. In this case, the vertical arm 5 is tilted to the left or right. , Can be placed vertically on the right or left.

(The effect of selecting the left side and the right side and placing them vertically)
When wrapping the roll bale R before wrapping with the wrapping device 1, there are roughly two methods. One is the case where the roll bale R released by the roll baler into the field is wrapped on the spot. The wrapped roll bale R is eventually collected by a bale gripper 8 or the like, and is carried out of the field by a truck or the like. In order to transport the roll bale R in the field as efficiently as possible, by placing it vertically on the side near the road or on the side near the collection point of the roll bale R, the transportation distance can be shortened and the work efficiency of collecting the roll bale R can be shortened. Can be enhanced.

The other is a case where the roll bale R before wrapping is collected at a predetermined place in the field as a collection place and wrapping is performed collectively. FIG. 13 is an explanatory diagram of a wrapping operation in a collection place using the wrapping device 1 of the embodiment. In this case, the wrapping device 1 does not move, and the bale gripper 8 as shown in FIG. 14 is often used to mount the roll bale R before wrapping on the wrapping device 1. FIG. 14 is a side view of the bale gripper 8, and FIG. 14 (A) is a side view of a state in which a roll bale R placed with the bottom surface R7 facing sideways is gripped. As can be seen from FIG. 14A, in order to grip the roll bale R placed with the bottom surface R7 facing sideways, the support arm 81 of the bale gripper 8 sandwiches the peripheral surface R6 of the roll bale R. There is a need. Therefore, in order to grip the roll bale R on which the bottom surface R7 is placed sideways, the bale gripper 8 must always approach from the bottom surface R7 of the roll bale R or the top surface direction.
Further, FIG. 14B is a side view of a state in which the vertically placed roll bale R is being gripped. The support arm of the bale gripper 8 is configured so that the head can rotate so that the bottom surface R7 can be gripped by either the roll bale R placed sideways or the roll bale R placed vertically. As can be seen from FIG. 14B, the support arm 81 of the bale gripper 8 grips the peripheral surface R6 of the vertically placed roll bale R. The vertically placed roll bale R has the same shape when viewed from any direction of the four circumferences, and when the bale gripper 8 grips the vertically placed roll bale R, it can be approached from any direction of the four circumferences.

Returning to FIG. 13, the hatched roll bale R indicates a wrapped roll bale R, and two wrapped roll balers R have already been collected in the foreground. In the (step 1), the roll bale R before wrapping is placed on the wrapping device 1 by the bale gripper 8 (not shown) as shown by the arrow, and the wrapping operation is performed.
(Step 2) is a state immediately after the roll bale R is lowered into the field and placed vertically.
(Step 3) is a step of carrying the vertically placed roll bale R by a bale gripper 8 (not shown). As described above, the vertically placed roll bale R has a cylindrical shape, and its shape does not change when viewed from any direction of the four circumferences. The bale gripper 8 can grip the roll bale R regardless of the direction in which the roll bale R is vertically placed. The bale gripper 8 approaches from the direction of good work efficiency and moves the wrapped roll bale R to the collection place.
The operator can consider the movement of the bale gripper 8 and operate the wrapping device 1 to vertically place the roll bale R on the right side or the left side in the direction in which the work efficiency is good.

FIG. 15 is an explanatory diagram of a lapping operation in a collection place using a conventional lapping device 1 that cannot be vertically placed.
(Conventional step 1) is not different from (Step 1) of the embodiment of FIG. In the (conventional step 2), since the conventional wrapping device 1 cannot vertically place the roll bale R, the roll bale R is lowered so that the bottom surface R7 is turned sideways and the peripheral surface R6 is in contact with the field. Therefore, an addition (conventional step 3) that did not exist in the embodiment of FIG. 13 is added. (Conventional step 3) is a work of vertically placing the roll bale R. At this time, as described above, in order for the bale gripper 8 to grip the roll bale R on which the bottom surface R7 is placed sideways, it is necessary to approach from the bottom surface R7 or the top surface direction of the roll bale R. Unlike (Step 3) of FIG. 13, the bale gripper 8 cannot be approached from any direction, and the work efficiency is greatly reduced. After that (conventional step 4), the vertically placed roll bale R bale gripper 8 wrapped roll bale R is moved to the accumulation place.
As described above, in the conventional wrapping device 1 that cannot be vertically placed, the work efficiency is lowered in the cooperation work with the bale gripper 8.

The action and effect of the examples of the present invention have been described by providing the item (action and effect in which the left side and the right side can be selected and placed vertically). The wrapping device 1 of the embodiment prevents the roll bale R from being punctured by vertically placing the wrap film vertically with the bottom surface R7 of the roll bale R thicker than the peripheral surface R6 facing down. If a hole is made, the wrap film is further consumed to close the hole, so that the wrapping device 1 of the embodiment contributes to the reduction of the environmental load. In addition to the action and effect of the wrapping device 1, it contributes to the work efficiency of the entire agricultural work such as collecting and transporting the roll bale R, and can save fuel and resources. The wrapping device 1 of the embodiment can contribute to the United Nations-led Sustainable Development Goals, "Promoting Sustainable Agriculture."

Although the wrapping device 1 of the embodiment according to the present invention has been described in detail with reference to the drawings, the specific configuration is not limited to these embodiments and does not deviate from the gist of the present invention. Even if there is a change in the design of the range, it is included in the present invention.

Further, each of the above-described embodiments can be combined by diverting the technologies of each other as long as there is no particular contradiction or problem in the purpose and configuration thereof. In particular, Example 5 can be used in combination with any of Examples 1 to 4.
