During the loading operation of the wrapping device 1, the vertical placement arm 5 lies down along the end face 24 of the roll bail support base 2 (indicated by the dotted line in FIG. 1(A)). Please refer to the location of (5)).

(lapping process)

Since the configuration and operation of the roll bale support unit 21 and the wrap film take-up device 7 are well known, the brief description is limited.

The roll bail support 21 horizontally rotates on the roll bail support base 2 during wrapping. The roll bale R before wrapping is placed so that its circumferential surface R6 is surrounded by a belt provided on the roll bale support 21, and is rotated little by little around the circumferential surface R6 to form a wrap film take-up device 7 The entire surface is wrapped by a wrap film installed between the and the roll bale R.

(roll bale unloading process)

When loading and unloading the roll bale R, as shown in FIG. The vertical positioning arm 5 retracted along is rotated in the direction of standing with respect to the roll bail support base 2.

Fig. 5 is a side view showing the unloading step of the roll bale R of the wrapping device 1 according to Example 1. Fig. 5(A) is a side view at the start of unloading, and Fig. 5(B) is during unloading. Side view of the city, Fig. 5 (C) is a side view when the roll bale R is lowered on the pavement.

At the start of loading/unloading, as shown in Fig. 5(A), the loading/unloading arm 4 supports the roll bale R. Then, the vertical positioning arm 5 is controlled by the vertical positioning control unit 6 so as to rotate in the direction of standing with respect to the roll bail support base 2 as described above.

As shown in FIG. 5(B) , the roll bail support base 2 gradually tilts around the tilt shaft 22 and moves away from the top of the frame 11 of the wrapping device. By the vertical positioning control unit 6, as shown in FIG. 5(C), tilting of the roll bale support base 2 until the cylindrical roll bale R is finally grounded on the pavement in a collapsed state. controlled Finally, the vertical positioning arm 5 attached to the rear end 25 of the roll bail support base 2 tilts the roll bail support base 2 and moves until it touches the ground.

In addition, although the above described the mode controlled by the vertical placement control unit 6, the roll bale R may be unloaded manually, and the mode in which the vertical placement control unit 6 is not provided is also included in the present invention do.

(Vertical arrangement process of roll bale)

When the roll bale support base 2 is sufficiently tilted, the roll bale R is grounded in a collapsed state on the pavement. At this time, the vertical arrangement arm 5 is sandwiched between the packaging and the roll bale R (see FIG. 5(C)). As shown in Fig. 1 (A), since the vertical positioning arm 5 is in a standing state (the position of the solid line), when viewed from the roll bale R, it shifts to one end side of the roll bale R in a collapsed state. The vertical positioning arm 5 comes into contact with the circumferential surface R6 of the roll bale R.

Next, the loading/unloading arm 4 is controlled by the vertical arrangement controller 6 so as to be separated from the roll bale R.

Fig. 6 (A) is a rear view at the time of starting the vertical arrangement process of the roll bale R, and Fig. 6 (B) is a side view at the time of the start of the vertical arrangement process of the roll bale R.

6(A) and 6(B), the loading/unloading arm 4 rotates to a position separated from the roll bale R, and in this state, the roll bale support base 2 First, with the tilting shaft 22 as a fulcrum, tilting is started in the direction entering the frame 11 of the lapping device. In addition, the movement of the roll bale support base 2 is the same as the step of loading the roll bale R.

When the roll bail support base 2 starts tilting, the vertical positioning arm 5 mounted on the roll bail support base 2 rises. As described above, since the vertical positioning arm 5 is shifted toward the one end side of the roll bale R and is in contact with the circumferential surface R6 of the roll bale R, the one end side of the roll bale R is gradually started to be lifted. Thus, the roll bale R is finally placed vertically.

In the vertical positioning process, the roll bale R and the vertical positioning arm 5 come into contact, and the vertical positioning arm 5 slides the circumferential surface R6 of the roll bale R as it rises, At that time, there was a case where the wrap film wound around the roll bale R was damaged. As shown in FIG. 6(C), the vertical arm 5 of Example 1 has a structure in which a cylindrical core 54 is covered with a cylindrical exterior material 55, and a cylindrical exterior material ( 55), since the cylindrical sheathing material 55 of the vertical positioning arm 5 configured to freely rotate around the core material 54 rotates freely, there is a case where the wrap film wound around the roll bale R is not damaged. is supposed to be absent.

The movement of each member of the wrapping device 1 in the series of vertical roll bale arrangement steps is also controlled by the vertical arrangement control unit 6 in the first embodiment, but may be moved manually, and the vertical arrangement control unit 6 ) is also included in the present invention.

(Summary of Example 1)

The driving source when the vertical positioning arm 5 lifts the roll bale R in a collapsed state is the tilt drive unit 23 for tilting the roll bail support base 2, and in order to lift the roll bail R There is no need to provide a separate driving source, and the structure of the lapping device 1 can be simplified.

In addition, in the vertical arrangement of the roll bale R, after the roll bale R is grounded on the vertical arrangement arm 5, the roll bail support base 2 supporting the vertical arrangement arm 5 is lifted. It can be performed with a simple movement, and the efficiency of the vertical arrangement work of the roll bale R can be achieved.

In addition, the bottom surface R7 of the roll bale R is thicker than the circumferential surface R6 of the cylindrical roll bale R, so that the overlapping of the wrap film is multiple, so projections such as residual gaps are stuck and the wrap film can reduce the probability of drilling a hole in

<Example 2>

Each member provided in the lapping device 1 is the same as in Example 1. In addition, the movement of each member of the lapping device 1 up to the unloading step is the same as in the first embodiment.

(Vertical arrangement process of roll bale)

In some cases, the package on which the roll bale R is to be placed vertically is inclined so that the side on which the roll bale R is unloaded is lowered. In such a case, if the loading/unloading arm 4 moves away from the roll bale R, there is a possibility that the roll bale R will be separated from the wrapping device 1 by rolling due to the inclination of the pavement. In addition, even if the pavement is flat, if the roll bale R is light, there is a possibility that the roll bale R will move away from the wrapping device 1 due to the separation operation of the loading/unloading arm 4.

In addition, in pavement where the direction in which the roll bales R are vertically arranged is inclined downward, the momentum may be excessive and the vertically arranged roll bales R may overturn and fall over.

Therefore, in Example 2, the loading/unloading arm 4 does not separate the roll bale R from the roll bale R during the step of vertically arranging the roll bale R, and moves the roll bale R to such an extent that the vertical arrangement is not hindered. The loading/unloading arm driving unit 41 is controlled by the vertical arrangement control unit 6 so as to move as if supported. Fig. 7 is an explanatory view of the vertical arrangement process of the roll bale R according to Example 2, and is a perspective view of Fig. 7 (A) and a rear view of Fig. 7 (B). As shown in FIG. 7(A) and FIG. 7(B), the roll bale R is supported by the loading/unloading arm 4 to such an extent that there is no hindrance to the vertical arrangement of the roll bale. (R) to prevent rolling the pavement. When the roll bail support base 2 starts tilting, the vertical positioning arm 5 attached to the roll bail support base 2 also rises and gradually starts lifting one end side of the roll bail R. Since the loading/unloading arm 4 is controlled by the vertical arrangement control unit 6 so as to support the roll bale R to the extent that the vertical arrangement is not hindered, the direction in which the roll bale R is vertically arranged is lowered. Even when it is tilted so that the roll bale R is gently vertically arranged, it is not overturned.

It is the same as in the first embodiment that the loading/unloading arm driving unit 41 may be manually controlled without being controlled by the vertical arrangement control unit 6.

On an inclined land, there is a case where the vertical arrangement of the roll bale R failed, and there was also a case where the roll bale was vertically disposed again for the failed roll bale R, but in Example 2, even on an inclined land, the roll bale ( There are few cases in which the vertical arrangement of R) fails, so that the efficiency of the vertical arrangement of the roll bale R can be achieved.

In addition, since the overlapping of the wrap film is gently arranged vertically below the bottom surface (R7) of the multi-thick roll bale (R), the probability of puncturing the wrap film due to projections such as residues can be lowered. there is. In addition, when the vertical arrangement fails, projections such as residues may be embedded in the circumferential surface R6 of the roll bale R where the overlapping of the wrap film is thin, resulting in a hole in the wrap film. In Example 2, since the loading/unloading arm 4 is controlled by the vertical positioning control unit 6 so as to support the roll bale R to the extent that the vertical positioning is not hindered, the vertical positioning fails and holes are formed in the wrap film. It can reduce the chance of breaking through.

<Example 3>

Each member provided in the lapping device 1 is the same as in Example 1. In addition, the movement of each member of the lapping device 1 up to the lapping step is the same as in the first embodiment.

(Vertical arrangement process of roll bale)

At the time of vertical arrangement of the roll bail R, as shown in FIG. It is rotated by the vertical arrangement arm drive part 51 in the direction to stand up with respect to the roll bail support part base 2 from the state retracted along.

Fig. 8 is an explanatory diagram of the vertical arrangement process of the roll bale R according to Example 3, Fig. 8 (A) is a side view at the start of discharge, and Fig. 8 (B) is a roll bale support base 2 It is a side view when the roll bale R is released by inclining.

In Example 3, when the release of the roll bale R starts, the vertical arrangement control unit 6 separates the loading/unloading arm 4 from the roll bale R as shown in FIG. 8(A). In this state, the roll bail support base 2 is controlled to tilt.

In the momentum of release and falling of the roll bale R from the tilted roll bale support base 2, the end of the circumferential surface R6 of the roll bale R corresponds to the vertical arrangement arm 5, and the roll bale R are placed vertically.

The package on which the roll bale R is to be placed vertically is inclined so that the side on which the roll bale R is unloaded is lowered, and the momentum of the roll bale R increases and the roll bale R is not properly vertically positioned. there is. In such a case, according to the inclination angle of the packaging or wrapping device 1 detected by the inclination angle detector 8 provided in the wrapping device 1 shown in FIGS. 8(A) and 8(B), the roll The tilting speed of the bail support base 2 may be controlled by the vertical arrangement controller 6 so as to be lowered.

Conversely, the package on which the roll bale R is intended to be placed vertically is inclined so that the side for loading and unloading the roll bale R is raised, and the momentum of the roll bale R is weak and the roll bale R is not properly vertically positioned. There are cases where it doesn't. In such a case, you may make it control by the vertical arrangement control part 6 so that the tilting speed of the roll bail support part base 2 may be raised according to the inclination angle detected by the inclination angle detector 8.

It is the same as in the first embodiment that the loading/unloading arm 4 may be manually controlled without providing the vertical arrangement controller 6 or the inclination angle detector 8 and not controlling the load/unloading arm 4 .

On an inclined land, there is a case where the vertical arrangement of the roll bale R failed, and there was also a case where the roll bale was vertically arranged again for the failed roll bale R, but in Example 3, even on an inclined land, the roll bale ( There are few cases in which the vertical arrangement of R) fails, so that the efficiency of the vertical arrangement of the roll bale R can be achieved.

When the vertical arrangement fails, there is a case where projections such as residues are embedded in the circumferential surface R6 of the roll bale R where the overlapping of the wrap film is thin, resulting in a hole in the wrap film. In Example 3, there are few cases where the vertical arrangement fails, and thus the probability of holes being formed in the wrap film due to the failure of the vertical arrangement can be reduced.

<Example 4>

Each member provided in the lapping device 1 is the same as in Example 1. In addition, the movement of each member of the lapping device 1 up to the lapping step is the same as in the first embodiment.

(Vertical arrangement process of roll bale)

Fig. 9 is an explanatory view of the vertical arrangement process of the roll bale R according to Example 4, and Fig. 9 (A) is a side view at the time of starting discharge of the roll bale R, and this state is shown in Fig. 1 ( As shown in A), the vertical placement arm 5 moves from a state retracted along the roll bail support base 2 indicated by dotted lines in a direction to stand up against the roll bail support base 2 ( 51) shows the state rotated.

In addition, the loading/unloading arm 4 is rotated so as to support the circumferential surface R6 of the roll bale R by the loading/unloading arm drive unit 41 .

Next, in a state where the roll bale R is supported by the roll bale support 21 and the loading/unloading arm 4, the roll bale support base 2 ) to tilt. Then, as shown in FIG. 9(B), when the roll bail support base 2 reaches a predetermined inclination angle, the tilting of the roll bail support base 2 is stopped, and the loading/unloading arm 4 is moved to the roll bale R. It is controlled by the vertical arrangement controller 6 so that the roll bale R is released by separating from the .

The end of the circumferential surface R6 of the released and dropped roll bale R corresponds to the vertical arrangement bar 5, and the roll bale R is vertically arranged.

Inclination when the tilting of the roll bale support base 2 is stopped when the side for loading and unloading the roll bale R is inclined so as to descend or, conversely, when the side for unloading the roll bale R is inclined so as to rise. By adjusting the angle, the releasing and falling force 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 pavement.

Depending on the inclination angle of the packaging or wrapping device detected by the inclination angle detector 8 provided in the wrapping device 1, the inclination angle to stop the tilting of the roll bale support base 2 may be controlled by the vertical arrangement controller 6. do.

It is the same as in the first embodiment that the loading/unloading arm 4 may be manually controlled without providing the vertical arrangement controller 6 or the inclination angle detector 8 and not controlling the load/unloading arm 4 .

In Example 4, the release and falling force of the released roll bale R can be changed, and the roll bale R can be surely vertically arranged according to the inclination of the pavement, so that the roll bale R can be vertically arranged. Work efficiency can be achieved.

When the vertical arrangement fails, there is a case where projections such as residues are embedded in the circumferential surface R6 of the roll bale R where the overlapping of the wrap film is thin, resulting in a hole in the wrap film. In Example 3, there are few cases where the vertical arrangement fails, and thus the probability of holes being formed in the wrap film due to the failure of the vertical arrangement can be reduced.

<Example 5>

Each member provided in the lapping device 1 is the same as in Example 1.

As indicated by the dotted line in FIG. It is fitted to enter. As shown in FIG. 1(A) , the vertical placement arm 5 is centered on the vertical placement arm rotation axis 52 along the end face 24 of the roll bail support base 2 from the state where the roll is retracted. It rotates in the direction of standing with respect to the bail support base (2).

As described above, in the step of unloading the roll bale R, as shown in Figs. 5(A) to 5(C), the vertical arrangement arm 5 becomes horizontal.

The case of pavement in which the roll bale R is horizontal will be described first.

The midline R2 referred to below refers to a line drawn around the circumference of a cylinder at the midpoint in the height direction of the vertically arranged roll bale R (cylindrical shape) (Fig. 10 (A-b) ) reference). (In addition, the "middle line R2" is the criterion in the case of a horizontal pavement, but as will be described later, the center of gravity R5 is taken into account in an inclined pavement.)

Fig. 10 is an explanatory diagram relating to Example 5, and Fig. 10 (A-a) tilts the vertical positioning arm 5 closer to the right than the midline R2 of the roll bale R, so that the roll bale R It is a rear view of the lapping device 1 when it is grounded. 10(B-a) shows the wrapping device 1 when the vertical positioning arm 5 is moved closer to the left than the middle line R2 of the roll bale R and the roll bale R is grounded. It is a rear view.

As shown in Fig. 10(A-a) and Fig. 10(B-a), even if the vertical positioning arm 5 is tilted closer to the right than the middle line R2 of the roll bale R, the vertical positioning arm 5 Even if it is tilted closer to the left than the middle line R2 of the roll bale, the position of the vertical arm base 56 provided with the vertical arm pivot 52 does not change.

However, as shown in Fig. 10(A-b) and Fig. 10(B-b), the position of the vertical positioning arm 5 seen from the ground plane is the roll of the vertical positioning arm 5 as shown in Fig. 10(A-b). When tilted closer to the right than the middle line R2 of the bale R and as shown in (B-b) of FIG. 10, the vertical arrangement arm 5 is closer to the left than the middle line R2 It is different from when tilted.

The roll bale R is cylindrical, and when the roll bale R is unloaded according to the present invention, the roll bale R is unloaded so that the central axis of the collapsed cylindrical roll bale R is horizontal. At this time, the location where the roll bail R is grounded becomes a line shape as indicated by the grounding line R1. However, since the roll bale R is gently pressed slightly by its own weight, even if it is in the form of a line, it becomes a line with a width.

The vertical positioning arm tip 53 exceeds this ground line R1, and the intersection R4 of the vertical positioning arm 5 and the ground line R1 is the middle line R2 of the roll bale R If it does not exceed , and it is on the right side of the middle line R2, the vertical positioning arm 5 is tilted closer to the right than the middle line R2 in Fig. 10(A-b).

On the other hand, the tip of the vertical arm 53 exceeds this ground line R1, and the intersection R4 of the vertical arm 5 and the ground line R1 is the middle line of the roll bale R. When it exceeds (R2) and is on the left side of the middle line R2, the vertical positioning arm 5 is tilted closer to the right than the middle line R2 in Fig. 10(B-b).

When viewed from a perspective view, it is the same as FIG. 10 (A-c) and FIG. 10 (B-c), respectively.

From Fig. 10 (A-c) and Fig. 10 (B-c), it is only one point at the intersection R4 of the ground line R1 that the collapsed cylindrical roll bale R and the vertical positioning arm 5 come into contact. Able to know.

In this state, when moving to the above (roll bale vertical arranging process), the vertical arranging arm 5 mounted on the roll bale support base 2 starts to be lifted up. As shown in Fig. 10(A-b) and Fig. 10(A-c) , if there is a vertical positioning arm 5 closer to the right than the middle line R2, the vertical positioning arm 5 is connected to the ground line R1. Since it contacts the roll bale R only at the intersection point R4 (on the right side of the middle line R2), lifting of the fallen cylindrical roll bail R starts from this intersection point R4. Then, the fallen cylindrical roll bale R rises with the turning point R3 at the left end of the fallen cylindrical roll bale R shown in Fig. 10 (A-c) as a fulcrum. In this case, the roll bale R is vertically disposed on the left side as viewed from the back of the wrapping device 1. Fig. 11 is a perspective view showing the vertical arrangement position of the lapping device 1 according to the fifth embodiment as seen from the back side, and as shown here, "the vertical arrangement position in the case of Fig. 10 (A-c)", the wrapping device 1 A roll bale (R) is vertically arranged on the left side.

If the tip of the vertical positioning arm 53 does not exceed the ground line R1, the vertical positioning arm 5 is not in contact with the fallen cylindrical roll bail R. When the vertical positioning arm 5 is lifted together with the roll bail support base 2, the tip of the vertical positioning arm 53 only moves along the cylindrical circumferential surface R6 of the collapsed cylindrical roll bale R. However, the roll bale (R) cannot be lifted and placed vertically. For this reason, the vertical placement arm 5 needs to have a length such that the tip portion 53 of the vertical placement arm can exceed the ground line R1.

Similarly, as shown in (B-b) and (B-c) of Fig. 10, if there is a vertical positioning arm 5 closer to the left than the middle line R2, the vertical positioning arm 5 is connected to the ground line ( Since the roll bale R is contacted only at the intersection point R4 of R1 (which is on the left side of the middle line R2), lifting of the fallen cylindrical roll bail R starts from this intersection point R4. The fallen cylindrical roll bale R rises with the turning point R3 at the right end of the fallen cylindrical roll bale R shown in (B-c) of FIG. 10 as a fulcrum. The roll bale R is vertically disposed on the right side of the wrapping device 1 as shown in FIG.

(In the case of a slope that slopes left and right when viewed from the back of the lapping device)

The above description was about the case where the pavement was horizontal.

In the case of a slope that slopes to the left or right when viewed from the back of the lapping device 1, it is easy to vertically arrange on the lower side, but may not be able to vertically arrange on the raised side even if the vertical arm 5 is tilted. Fig. 12 is an explanatory diagram of a slope in Example 5;

On a flat land, since the middle line R2 passed through the center of gravity R5 of the roll bale R, the right half and left half of the rolled bale R had the same weight, and the arrangement of the vertical positioning arm 5 By changing whether to tilt to the right or to the left with respect to the middle line R2, it was possible to vertically arrange it on the right and left sides as shown in FIG. 11. However, on a slope that slopes to the left or right, it is necessary to tilt the vertical placement arm 5 in consideration of the center of gravity R5.

That is, as viewed from the rear surface of the lapping device 1, the tip of the vertically arranged arm 53 sufficiently exceeds the ground line R1, and also the intersection point R4 of the vertical line drawn from the center of gravity R5 and the ground line R1. ), whether the roll bale (R) is vertically arranged on the right or left side changes depending on whether it is on the right or left.

When the vertical arm tip 53 is on the right side of the intersection point 4, the roll bail R is vertically positioned on the left side, and as shown in FIG. When on the left side, the roll bale R is vertically arranged on the right side.

Fig. 12 is a perspective view of the roll bale when the vertical arrangement arm 5 is tilted to the left in consideration of the center of gravity R5 of the roll bale R. However, in the case of adopting the short vertical placement arm 5, if the vertical placement arm 5 is greatly tilted (the vertical placement arm 5 is greatly tilted), the tip of the vertical placement arm 53 is connected to the ground line R1. ) may not be exceeded.

This can be eliminated by using the long vertical arrangement arm 5 . However, when the long vertical arm 5 is employed, there are cases where the vertical arm 5 protrudes to the side beyond the base width of the wrapping device 1 . In such a case, it is also possible to respond by enabling the vertical placement arm 5 to be stretchable, shortening the vertical placement arm 5 in normal times, and extending it when dealing with slopes.

The vertical arrangement of the roll bale R is a simple movement of lifting the roll bail support base 2 supporting the vertical arrangement arm 5 after grounding the roll bale R on the vertical arrangement arm 5. As a result, it can be vertically arranged in either left or right direction, and the efficiency of the vertical arrangement work of the roll bale (R) can be achieved.

Further, the vertical placement arm 5 may be provided at the center of the rear end 25 (the side for unloading the roll bale R) of the roll bale support base 2. In this case, the vertical placement arm 5 By inclining to the left or right, it can be placed vertically on the right or left.

(Action effects that can be placed vertically by selecting the left and right sides)

When wrapping the roll bale R before wrapping with the wrapping device 1, there are largely two methods. One is a case where the roll baler wraps the roll bale (R) discharged into the package on the spot. The wrapped roll bale R is eventually collected by the bale gripper 8 or the like and then moved out of the package by a track or the like. In order to move the roll bale R in the pavement as efficiently as possible, the roll bale R is recovered by shortening the transport distance by arranging it vertically on the side close to the road or on the side close to the roll bale R accumulation site. work efficiency can be increased.

Another case is a case where the roll bales R before wrapping are collected at a predetermined location on the pavement as an accumulation area, and wrapping is performed collectively. Fig. 13 is an explanatory diagram of a lapping operation in an accumulation site using the lapping device 1 of the embodiment. In this case, in order to load the roll bale R before wrapping onto the wrapping device 1 without moving the wrapping device 1, a bale gripper 8 as shown in FIG. 14 is often used. Fig. 14 is a side view of the bale gripper 8, and Fig. 14 (A) is a side view of a state in which the roll bale R placed with the bottom surface R7 horizontally is gripped. As can be seen from (A) of FIG. 14, in order to grip the roll bale R placed horizontally on the bottom surface R7, the support arm 81 of the bail gripper 8 is ) It is necessary to sandwich the circumferential surface R6 therebetween. Therefore, in order to grip the roll bale R placed with the bottom surface R7 facing horizontally, the bale gripper 8 must necessarily approach from the bottom surface R7 or upper surface direction of the roll bale R there is

14(B) is a side view of a state holding the roll bale R vertically arranged. The support arm of the bale gripper 8 is configured so that the head can rotate so that it can grip either the roll bale R or the roll bale R vertically placed with the bottom surface R7 facing horizontally. there is. As can be seen from (B) of FIG. 14 , the support arm 81 of the bail gripper 8 grips the circumferential surface R6 of the vertically arranged roll bail R. The vertically arranged roll bale R has the same shape when viewed from any of the four circumferential directions, and when the bale gripper 8 grips the vertically arranged roll bale R, it cannot be approached from any of the four circumferential directions. there is.

Referring back to FIG. 13, the hatched roll bale R represents the wrapped roll bale R, and two already wrapped roll bales R are gathered at the front. In (Process 1), the roll bale R before wrapping is loaded onto the wrapping device 1 as indicated by the arrow by the bale gripper 8 (not shown), and the wrapping operation is performed.

(Process 2) is a state immediately after placing the roll bale R down on the pavement and arranging it vertically.

(Process 3) is a process of moving the vertically arranged roll bale R to the bale gripper 8 (not shown). As described above, the vertically arranged roll bail R has a cylindrical shape, and the shape does not change even when viewed from any of the four circumferential directions. The bale gripper 8 can grip the roll bale R even if it approaches the vertically arranged roll bale R from any direction. The bale gripper 8 moves the wrapped roll bale R to the accumulation site by approaching from a direction with good work efficiency.

The operator can think about the movement of the bale gripper 8 and operate the wrapping device 1 to vertically arrange the roll bale R in the right or left direction, which is more efficient in operation.

Fig. 15 is an explanatory diagram of a lapping operation in an accumulation site using a conventional lapping device 1 that cannot be placed vertically.

(Conventional step 1) is not at all different from (step 1) in the embodiment of FIG. 13 . In (conventional step 2), since the conventional lapping device 1 cannot vertically arrange the roll bale R, the roll bale R has the bottom surface R7 horizontally and the circumferential surface R6 It is lowered to ground with this packaging. For this reason, (conventional step 3), which did not exist in the embodiment of FIG. 13, is added. (Conventional process 3) is an operation of vertically arranging the roll bale R. At this time, as described above, in order for the bale gripper 8 to grip the roll bale R placed with the bottom surface R7 facing horizontally, the bottom surface R7 or the top surface of the roll bale R must be It is necessary to approach from the direction. Unlike (Step 3) of FIG. 13, the bale gripper 8 cannot be approached from any direction, which greatly reduces work efficiency. Thereafter, in (conventional step 4), the vertically arranged roll bales R are moved by the bale gripper 8 to the accumulation site.

In this way, in the conventional lapping device 1 that cannot be vertically arranged, work efficiency is lowered in the interlocking operation with the bale gripper 8.

With respect to the action and effect of the embodiment of the present invention, an item of (action and effect that can be vertically arranged by selecting the left and right sides) has been provided and explained. In the wrapping device 1 of the embodiment, the roll bale R is vertically disposed with the bottom surface R7 of the roll bale R having a thicker wrap film than the circumferential surface R6 facing down, thereby preventing the roll bale R from being punctured. If a hole is opened, the wrapping film is additionally consumed to close the hole, so the wrapping device 1 of the embodiment contributes to reducing the environmental load. In addition, it contributes to the work efficiency of the entire agricultural work such as collecting or transporting the roll bale R, without being limited to the effect of the wrapping device 1, so that fuel and resources can be saved. The wrapping device 1 of the embodiment can contribute to "promoting sustainable agriculture" which is the Sustainable Development Goal led by the United Nations.

In the above, the lapping device 1 of the embodiment related to the present invention has been described in detail with reference to the drawings, but the specific configuration is not limited to these embodiments, and changes in design within the range of not departing from the gist of the present invention Even if there is, it is included in the present invention.

In addition, each of the above-described embodiments can be combined by utilizing each other's techniques, as long as there is no particular contradiction or problem in the purpose or configuration. In particular, Example 5 can be used in combination with any of Examples 1 to 4.
