DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roll veil obtained by winding a pasture into a roll with a roll baler and forming it into a high-quality silage. The present invention relates to an improvement in a bale releasing device that releases a bale of a completed roll veil from a support base in a wrapping machine that winds and wraps a roll bale in an airtight manner.

[0002]

2. Description of the Related Art Using a wrapping machine A, a roll bale B is wrapped with a plastic film f.
At the end of this, the means for releasing the roll bale B from the bale support 1 of the wrapping machine A includes
, The second means shown in FIG. 2, the third means shown in FIG. 3, and the fourth means shown in FIG.

The first means shown in FIG. 1 is to tilt a bale support 1 provided on a machine frame a of a lapping machine A around a fulcrum shaft 10 toward the rear of the machine frame a,
The center of gravity G of the roll bale B on which the plastic film f is wound while being mounted on the upper surface of the bale support 1 is moved to move the roll bale B from the upper surface of the bale support 1 to the ground behind the machine frame a. This is a means for rolling down on the surface GL.

[0004] A second means shown in FIG. 2 is that a bale support 1 of a lapping machine A is mounted on a bale supporter 1 such that a roll bale B to be supported can be freely rolled at that position around the center of its axis. A pair of rollers 11 and 12 to be kept
Are supported so that their opposing intervals expand and contract, and when the packaging operation of the roll bale B with the plastic film f is completed, the pair of rollers 1
This is a means for dropping the roll bale B onto the ground surface GL from between the pair of rollers 11 and 12 by widening the facing distance between the rollers 1 and 12 widely.

A third means shown in FIG. 3 is different from the first means shown in FIG. 1 in that an arm 2 for holding a roll bale B mounted on an upper surface of a bale support 1 from above is mounted on the bale support. 1 and the fulcrum shaft 1 of the bale support 1
The operation of rolling the roll bale B to the rear of the machine frame a by the rotation about the center 0 is performed while the roll bale B is held by the arm 2 on the surface of the bale support 1, and the roll bale B is moved to the ground surface GL. Arm 2
Is opened and the roll bale B is discharged to a predetermined position behind the machine frame a.

Further, a fourth means shown in FIG. 42 rotates the front roller 12 of the support base 1 of the roll bale B rearward about a fulcrum shaft 60 on the front upper side of the machine frame a of the lapping machine A. Thus, the center of gravity G of the roll bale B with respect to the rear roller 11 of the bale support 1 is moved, and the roll bale B is rolled from the upper surface of the rear roller 11 onto the ground surface GL behind the machine frame a. It is a means to drop.

The first to fourth roll bale B
The release means is a means in which the roll bale B to be released is released in a posture in which the trunk surface of the roll bale comes into contact with the ground surface GL.

[0008]

A plastic film f is applied to the outer peripheral surface of a roll bale B by a lapping machine A.
As shown in FIG. 4, the packaging operation performed by winding the roll bale B mounted on the upper surface of the bale support 1 of the wrapping machine A is performed by a roller 11 provided on the bale support 1.
The drive roller 11 of the 12 is driven to rotate, so that it is slowly rolled on the bale support 1 around the center of the axis, and at the same time, the roll bale B is rotated by the bale support 1 so that the center of gravity of the roll bale is moved. The plastic film f unwound from the film bundle F pivotally supported on the film bracket 3 by turning about the vertical line passing through G, the winding position on the roll bale B is sequentially displaced in the circumferential direction of the roll bale B. It is performed by winding while making it.

At this time, the operation of winding the plastic film f around the roll bale B, as shown in FIG. 5, is performed while the bale support 1 is fixed and the winding bundle F of the plastic film f is pivotally supported. The film bracket 3 is rotated so as to rotate around the bale support 1, and at the same time, a pair of rollers 11 on the upper surface of the bale support 1.
There is also a means for driving the drive roller 11 out of 12 to slowly roll the roll bale B around the center of the axis to sequentially displace the winding position of the film f in the circumferential direction.

The roll bale B is wrapped around the outer peripheral surface thereof by the operation of the wrapping machine A, as shown in FIG. 6, and is packaged as shown in FIG. B, the rotation speed of the roll bale B about the axis and the rotation speed of the roll bale B about the vertical line passing through the center of gravity G or the rotation speed of the film bracket 3 The plastic film f is wound by being polymerized at a constant overlapping ratio set by the ratio, and at both end surfaces in the axial direction, the peripheral edge thereof is a plastic film f wound around the body circumferential surface. However, most of the layer except for the peripheral portion overlaps the multilayer.

By the way, when the roll bale B packaged as described above is discharged from the upper surface of the bale support 1 of the wrapping machine A upon completion of the packaging, as described above,
By rolling around the center of the axis, the trunk surface comes into contact with the ground surface, so that the portion of the plastic film f wound around where the number of overlapping layers is small contacts the ground surface. I will go.

For this reason, the packaging of the roll bale B by the wrapping machine A is usually performed on a meadow,
The weight of the roll bale B itself at the time of falling when the part of the torso peripheral surface of the roll bale B, which is released after packaging and has a small number of overlapping plastic films f, hits a hard foreign substance such as a stump of grass or a piece of stone. In many cases, the plastic film f is perforated or damaged by the rolling (usually about 1 ton) and the rolling thereof, thereby causing a problem that the quality of the silage is deteriorated due to the invasion of air or rainwater.

[0013] Further, after the packaging is completed, the roll bale B is left on the meadow for a while. By stopping on the peripheral surface and being damaged by the bird's leg claw at that time, and being further poked with a beak,
There is a problem that the packaging is damaged and the quality of the silage is deteriorated.

Further, since the body peripheral surface side where the number of overlaps of the wound plastic film f is small is left on the upper surface side, rainwater permeates through the overlapping seam portion of the wound plastic film f. There is a problem that the probability is high and the quality of silage is often deteriorated.

Further, from the bale support 1 of the wrapping machine A, the roll bale B released after the packaging is completed,
When the pasted land on which the lapping work was performed is on a sloping land, the roll bale B that has been released rolls down from the position where the wrapping work is released to the slope-downward side because the axis line is in the horizontal direction, which is unsafe. Thus, there is a problem that the discharge to the predetermined position cannot be performed accurately.

Further, a wrapping operation is performed on a pasture, and the roll bale B is discharged to the pasture and left to stand.
When the transport vehicle is transported and stored in a storage house or the like using a transport vehicle, the roll bale B is mounted on the carrier of the transport vehicle, and when transported and accumulated in the storage location, the roll bale B is used. In order to stabilize it in a predetermined position, its roll bale B
Are converted into postures in which both end faces in the axial direction of the axis face up and down, and work is performed with one end face in contact with the ground.

At this time, the roll bale B is gripped one by one by a usual bale gripper which is mounted on a front surface of a traveling vehicle such as a tractor or the like, and both end surfaces in the axial direction of the shaft are turned up and down. It is necessary to perform a work of turning the body 90 degrees so as to be in a posture and changing to a state in which one end face is in contact with the ground, and this work is troublesome.

Meanwhile, the above-mentioned problem that occurs in the conventional means is that when the roll bale B that has been packaged is discharged from the bale support 1 of the wrapping machine A, the roll bale B is removed from both end faces in the axial direction. Is released in a vertical position, and if one end face is grounded and the other end face is the top face, these two end faces are parts where the number of overlapping plastic films f wound around it is large. Therefore, it is unlikely to be damaged when it comes into contact with the ground surface, and when it is released and released to the pasture, the top surface where birds stop will be a part with a large number of layers, so it will not be damaged In addition, it is possible to effectively prevent rainwater from permeating, to prevent rolling from the discharge position on the slope, and to rotate 90 degrees for transportation and storage. Thus, these problems can be solved at once, but a mechanism for changing the position of the roll bale B and discharging the same and an operation of the mechanism are required, which complicates the mechanism and complicates the operation. Another problem comes up.

The present invention has been made in order to solve the above-mentioned problem which has occurred in the roll bale discharging means in the conventional wrapping machine. The mechanism for turning the bale support 1 for releasing the bale B and the operation of the wrapping machine A for the release operation are not changed and a simple mechanism is used.
It is an object of the present invention to provide a new means for converting the roll bale B released from the bale support 1 into a posture in which the direction of the axis of the bale is vertical, so that the roll bale can be released to the ground surface. .

[0020]

According to the present invention, as a means for achieving the above-mentioned object, a bale support 1 mounted on a machine frame a of a lapping machine A is provided.
A guide g on which the roll bale B rolled and released from the bale support 1 rides on the discharge side of the roll bale B rolled and released from the center of the axial line,
When viewed in the discharge direction, the roll bale B is offset to one side in the axial direction of the roll bale B with respect to the position of the center of gravity G of the roll bale B, and is mounted so as to protrude in the discharge direction. A bale reversing / ejecting device for a wrapping machine, characterized in that the roll bale (B) discharged from the support table (1) is rotated and inverted to a posture in which the axis of the roll bale is vertical and discharged to the ground surface (GL). It is to raise.

[0021]

According to the means of the present invention constructed as described above, the rotation of the floating roller 12 constituting the bail support 1 toward the roll bale discharge side causes the roll bale B to move toward the roll bale discharge side of the machine frame a. As shown in FIG. 13, when the roll bale is rolled toward the roll bale discharge side of the machine casing a, the axis of the roll bale B is shifted with respect to the position of the center of gravity G of the roll bale B as shown in FIG. It shifts on the guide g which is offset in the center line direction and is provided in the form of a rail along the discharge direction, is supported by it, loses its balance due to the gravity of the roll bale B, and has its side offset with respect to the guide g. Turning to the opposite side, as shown in FIG. 14, one end b of the trunk surface comes into contact with the ground surface GL.

At this time, since the vertical line W passing through the center of gravity G of the roll bale B is outside the grounded one end b as shown in FIG. 14, the roll bale B is rotated by its own weight. The turning is continued in the turning direction with the one end b as a fulcrum by the force, and as shown in FIG. 15, one end face in the axis direction of the axis is in contact with the ground and is stabilized. Into a released state.

[0023]

Next, an embodiment will be described in detail with reference to the drawings. In the drawings, the same reference numerals are used for components having the same effects as those of the conventional means.

FIG. 7 is a perspective view of a lapping machine A embodying the present invention, and FIG. 8 is a side view of the same, and FIG.
Is a machine frame, 1 is a bale support mounted on the rear end side of the machine frame a, and g is a guide provided at the rear end of the machine frame a on the discharge side of the roll bale B so as to project rearward. Is shown.

The wrapping machine A is of a towed type in which the tractor (not shown) is connected and towed to the rear portion of the body of the tractor (not shown). Is provided with a connecting rod 4 connected to the connecting hitch provided in the vehicle.

The connecting rod 4 is connected to the front end of one of the left and right sides of the machine frame a so as to be rotatable left and right about a fulcrum shaft 40, and
The rotation thereof is performed by the operation of a hydraulic cylinder 41 which is connected to a hydraulic circuit of a hydraulic device mounted on the body of the tractor via a hydraulic hose and operated.

Then, as shown in FIG. 7, the machine frame a is moved forward by the traveling of the tractor with the front end side opened forward by the rotation of the connecting rod 4 to the side. The roll bale B, which is left on the surface of the field, is accommodated in the machine frame a from the opening which is offset to the side of the tractor when viewed from the traveling direction of the tractor.

On the machine frame a, a cage 5 which rises in a tower shape is mounted on the upper surface side thereof, and a lift arm having a top end supported by a support shaft 60 is provided on the front end side of the cage 5. 6
Is mounted so as to rotate back and forth by the operation of the hydraulic cylinder 61, and a floating roller 12 is pivotally supported at the lower end thereof.

The bail support 1 mounted on the rear end of the machine frame a is supported by the horizontal end of the rear end of the machine frame a via a hydraulic circuit of the hydraulic device of the tractor and a hydraulic hose. A drive roller 11 driven by a hydraulic motor operated by connection and a floating roller 12 pivotally supported at the lower end of the above-described lift arm 6 maintain a predetermined interval as shown by a chain line in FIG. In parallel.

That is, the roll bale B taken into the machine frame a as shown by a chain line I in FIG. While pushing up the front end of the peripheral surface above the drive roller 11, the rear end of the lower peripheral surface is supported by the floating roller 12, and the state shown by the chain line II in FIG. The idle roller 12 in the state position constitutes the bale support 1.

The lift arm 6 is controlled so that its rearward rotation operation is stopped in a state where the floating roller 12 at the lower end and the drive roller 11 are at a position constituting the bail support 1. In this state, by driving the drive roller 11, the roll bale B to be supported is rolled about the center of the axis of the roll bale.

The cage 5 supported on the upper surface of the machine frame a has, on its ceiling, a rotating arm 31 that pivots about a support shaft 30 by a hydraulic motor M that operates by being connected to a hydraulic device on the tractor side. Are supported at the lower ends of both the free ends which are curved and descend, and film brackets 3 which support the winding bundle F of the plastic film f are provided,
The film f unwound therefrom is supported on the upper surface of the above-mentioned bale support base 1 and is rotated by the driving of the drive roller 11 onto the peripheral surface of the roll bale B which is slowly rolling around the axis. The film is wound and packaged at the rotation speed of the film brackets 3, which rotate around the roll bale B by the rotation operation of the arm 31.

In order to release the roll bale B from which packaging has been completed from the upper surface of the bale support 1, the operation of releasing the bale support 1 is performed by the floating roller 12 pivotally supported at the lower end by the bale support. The lift arm 6 stopped at the position serving as the platform 1 is further rotated rearward from the state, and the floating roller 12 is displaced rearward and upward as shown in FIG. is there. For this reason, in this example, the discharge direction of the roll bale B is directed to the rear of the machine frame a.

Next, FIG. 10 shows the wrapping machine A described above.
In the same figure, a is a machine frame, 11 is a driving roller pivotally supported at the rear end of the machine frame a, and 12 is a floating roller pivotally supported at the lower end of the lift arm 6. The bale support 1 is located at a position where the bale support 1 is constituted by the drive roller 11, and a roll bale B is mounted thereon as indicated by a chain line.

In this example, since the discharge side of the roll bale B is located at the rear side of the machine frame a, the machine frame a
The guide g provided on the roll bale discharge side is provided so as to extend rearward from the rear frame a 'of the machine casing a.
The guide g converts the roll bale B, which is released toward the rear of the machine frame a by the release rotation of the bale support 1, while turning the roll bale so that the axial direction thereof is changed to the vertical direction. The roll bale B rolls from the upper surface of the bale support 1 in a posture in which the axis of the shaft is in the left-right direction.
With respect to the left and right central portions, which are the positions of the center of gravity G, as shown in FIG. It is mounted on a rear frame a 'of the machine frame a so as to extend rearward from the rear end of the machine frame a at substantially the same height, and a caster wheel 70 is supported at the rear end of the frame. It is.

The guide g moves the roll bale B which is rolled and pushed out in the discharge direction of the roll bale B by the discharge rotation of the bale support 1 as shown in FIG. At a position offset by a deviation X in the direction of the axis of the roll bale B with respect to the vertical line W passing therethrough, so that the roll bale B is guided by a rotational couple given by its own weight. In the center, the roll is turned in the direction opposite to the offset direction, and as shown in FIG. 14, one end b of the body circumferential surface of the roll bale B is brought into contact with the ground surface GL. By rotating the roll bale B in the above-described direction with the one end b grounded by the rotating couple as a fulcrum, as shown in FIG. Acts to the state will be grounded at one end face. Further, r is a guide wheel for smoothing the movement of the roll bale B moving from the bale support 1 to the guide g.

At this time, if the vertical line W passing through the center of gravity G of the roll bale B is located inside the one end b of the body circumferential surface abutting on the ground surface GL in the turning direction as shown in FIG. The rotation in the turning direction by the rotation couple cannot be continued, and returns to the original state.

Accordingly, the offset amount X and the height H of the guide g are determined by the vertical line W passing through the center of gravity G of the roll bale B.
It is necessary that the roll bale B be in contact with the ground surface GL so that the roll bale B is positioned outside the one end b of the trunk circumferential surface in the turning direction. The bale B continues to rotate in the direction of rotation around the center of the one end b, which is a ground contact point, due to its rotational couple due to gravity, and one end face in the axial direction of the roll bale B is grounded and stabilized. The two end faces in the axial direction are turned 90 degrees so as to face the vertical direction, and are discharged to the rear of the machine frame a.

After the packaging is completed, the roll bale B released from the bale support 1 is transferred onto a guide g offset in the axial direction with respect to the center of gravity G of the roll bale. Means for turning by a rotational couple due to the weight of B itself and converting the posture to an orientation in which the axial center direction is the up and down direction and releasing the same is to increase the ground height H of the guide g or to adjust the offset amount X of the guide g. By reducing the size and shortening the distance from the guide g to one end b of the body circumferential surface, reliable operation can be obtained.

However, as shown in FIG. 17, the height g of the guide g is higher than the bearing surface of the drive roller 11 on the rear end side of the bail bearing table 1 that has been released and rotated.
When the bale support 1 is released and rotated, there is a possibility that the transfer of the roll bale B onto the guide g may not be performed properly, and the offset amount X may be reduced. If it is made too small, on a slope, the vertical line W passing through the center of gravity G of the roll bale B will be
By being positioned on the right side as shown in FIG. 18 or on the left side as shown in FIG. 19 with respect to the guide g, the turning direction of the roll bale B becomes inconsistent in either direction. .

The means shown in FIGS. 20 to 22 is effective for this. That is, the guide g is the main guide g
1 is arranged at the central portion in the axial direction of the roll bale B so as to correspond to the position of the center of gravity G, and is provided so as to extend toward the rear of the machine casing a along the discharge direction. Another guide g2 that is substantially parallel to the guide g1 is arranged at a position that is deviated to the side opposite to the side on which the roll bale B is turned on one side of the guide g1, and the other guide g2 is
As shown in FIG. 21, the support surface is provided so as to be gradually higher than the guide g <b> 1, whereby the bale support base 1 is released and rotated rearward, and the roll bale B is moved to the machine frame a. When the roll bale B is discharged backward, the roll bale B moves onto the main guide g1 and the second guide g2, and the roll bale B is reversed and rotated by the second guide g2 as shown in FIG. Become.

FIG. 23 shows still another embodiment. In this embodiment, a roll bale B is discharged from the bale support 1 toward the rear of the machine frame a at the rear end of the machine frame a.
This is an example in which a guide g provided so as to be turned around is provided obliquely so as to gradually move away from the rear in the offset direction in plan view so that the offset amount X gradually increases toward the rear end side. Reference numeral 24 denotes an example in which the guide g is obliquely bent in the offset direction in a plan view from the middle, so that the offset amount X gradually increases from the middle.

Next, FIG. 25 shows the offset amount X of the above-mentioned guide g provided so as to protrude rearward at the rear end portion of the machine frame a.
Is an example that can be adjusted.

In this example, the guide g has its base end connected to a shaft cylinder 71 which is slidably fitted to the rear frame a 'of the machine frame a to the left and right.
Hydraulic cylinder 7 that expands and contracts in the left-right direction between
2, the shaft cylinder 71 is moved left and right by the expansion and contraction operation of the shaft 2 so that the offset amount X changes to a large or small value.

This is because when the diameter of the roll bale B supplied to the wrapping machine A changes to a large or small size depending on the form of the roll bale for molding the same, the roll bale B is
Can be accurately turned in a predetermined turning direction.

As shown in FIG. 26, a guide g for reversing the roll bale B has an offset amount X thereof.
Even if the height H is set appropriately with respect to the vertical line W passing through the center of gravity G of the roll bale B, if the diameter d of the roll bale B is small as shown in FIG. As the position moves downward, a vertical line W passing through the center of gravity G becomes
27, the roll bale B cannot be turned around as shown in FIG.

Further, even if the diameter of the roll bale B is constant, when the pasture to be worked is on an inclined land, a situation arises in which the roll bale B cannot be turned over as shown in FIG.

In such a case, the guide g will be described with reference to FIG.
As shown in FIG. 30, by adjusting the displacement in the offset direction, the roll bale B can be properly turned around.

FIG. 31 shows a modification of the embodiment shown in FIG. In this example, the offset amount X of the guide g is changed by moving the shaft cylinder 71 slidably fitted to the rear frame a 'of the machine frame a by the operation of the hydraulic cylinder 72 in the above-described embodiment. On the other hand, the movable range of the barrel 71, which is slidable left and right with respect to the rear frame a 'of the machine frame a, includes a large number of through holes 73 provided in series in the left and right direction of the rear frame a' of the machine frame a. This is an example in which the change amount of the offset amount X can be adjusted by changing it with the pins 74 inserted in the through holes 73 selected from those, and the operation is the same as in the above-described embodiment.

FIG. 32 shows a roll bale B having a heavy weight.
(Typically about 1 ton) is supported by the guide g and the plastic film f wound and packaged around the outer periphery of the roll bale B is prevented from being damaged by the contact surface pressure with the guide g. An example in which the contact surface pressure of the peripheral surface of the roll bale B with respect to the guide g is reduced in order to achieve this will be described.

In this example, the guide g is formed in a flat band shape long in the front and back or a flat band shape in which the left and right side edges are curved downward, and the base end thereof is a machine frame. a is formed separately so as to freely move with respect to the rear frame a ′, and the side edge of the lower surface side of the offset side is attached to the rear frame a ′ as shown in FIG. A spring supporting rod which is supported on the upper surface of a fixed fulcrum shaft 75 so as to be tiltable and swingable to the left and right, and is provided so as to protrude downward from the fulcrum shaft 75 with the offset side edge beyond the fulcrum shaft 75 76
A spring 77 which normally holds the flat plate-shaped guide g in a posture where the upper surface thereof is in a horizontal state between the lower end of the
Roll bale B from the bale support 1
Is pushed rearward, rides on the upper surface of the flat band-shaped guide g as shown in FIG. 33, and from that state,
The roll bale B is offset by the guide g as shown in FIG.
And the flat belt-shaped guide g keeps the upper surface in contact with the bottom surface side of the body peripheral surface of the roll bale B, and the roll bale B is centered on the fulcrum shaft 75. The roll bale B is tilted and rotated together, and the one end b of the guide g opposite to the offset side is brought into contact with the ground surface GL, and the center of the one end b is inverted by the rotation couple by the center of gravity G. This is an example in which when it is released, it returns to a flat posture by the traction by the spring 77 described above.

In this example, the contact surface between the lower surface side of the body circumferential surface of the roll bale B and the upper surface of the guide g is made wider by forming the guide g into a wide flat band-like shape. And the flat belt-shaped guide g is brought into contact with the lower surface of the circumferential surface of the roll bale B, and the roll bale B
Since the roll bale to be supported is hardly slid with respect to the circumferential surface of the roll, the breakage caused in the wrapped plastic film f when the roll bale B is inverted is effectively prevented. Will prevent it.

Next, FIG. 35 shows another embodiment. This embodiment is an example in which the means for forming the guide g shown in FIG. 32 described above in a flat strip shape is combined with the means for allowing the guide g shown in FIG.

In this embodiment, the guide g is formed in a flat strip shape, the rear end of the guide g is supported by the caster wheel 70, and the front end is provided on the rear frame a 'of the machine frame a. The fulcrum shaft 75 is tiltably and rotatably supported left and right, and
A spring 77 is stretched between a spring supporting rod 76 provided on the fulcrum shaft 75 and a side edge on the offset side of the flat band-shaped guide g, and the flat band-shaped guide g is normally held. As described in FIG.
2. The same as the embodiment shown in FIG.
A fulcrum shaft 75 provided on the rear frame a ′ of the machine frame a in order to support the base end side (front end side) of the
The rear part frame a 'is supported by a shaft cylinder 71 fitted slidably left and right.

Then, as shown in FIG. 31 described above, a plurality of through-holes 73 provided in series on the left and right sides of the rear frame a 'of the machine casing a as shown in FIG. Pins 74 inserted into the through holes 73
Thus, the guide g is displaced in the left-right direction, which is the offset direction, so that the offset amount X can be freely changed and adjusted.

In this embodiment, the advantage that the guide g is formed in a flat strip shape and the advantage that the offset amount X of the guide g is adjustable can be obtained together.

Next, FIG. 36 shows another embodiment. This embodiment is a modification of the embodiment shown in FIGS.

In this embodiment, a wrapped roll bale B which is rolled from a bale support 1 provided at the rear end of the machine frame a toward the rear of the machine frame a and discharged is mounted on the rear frame of the machine frame a. A guide g provided so as to project rearward from a ′ supports the roll bale B in a vertical direction with respect to the position of the center of gravity G of the roll bale B. This is an example in which a plurality of guides g are provided in parallel when turning and reversing the posture.

In this example, the guides g1
One of g2, g3,... protrudes rearward as a main guide g at a position corresponding to the left and right central portions which are the positions of the centers of gravity G of the roll bale B rolling rearward from the bale support 1. The second guide g2 and the third guide g3 are provided in parallel on one side of the left and right sides of the guide g1, and the second and third guides g2 and g3 are provided in parallel.

As a result, as shown in FIG. 37, the roll bale B rolling on the guides g1, g2, and g3 is turned around as shown in FIGS. 38 and 39. It is like that.

In this example, parallel guides g1 · g
.. May be made to be a larger number, and the parallel guides g1, g2, g3... May be continuous in a single plate shape. It may be formed.

FIG. 40 shows still another embodiment. In this example, a guide g provided so as to protrude rearward from a rear frame a 'of the machine frame a can be stored on the upper surface of the machine frame a.

In this example, a rear frame a ', which is a frame on the rear end side of the machine frame a, is formed in a shaft rod shape, and both ends of the rear frame a' are freely rotated about the axis of the machine frame a. The rear end of the guide g is supported on the rear frame a 'by the base end side (front end side) of the guide g.
When the caster wheel 70 is attached, the normal state is as shown in FIG. 40. When the guide g is not used as in the case of moving the lapping machine A, the guide g is attached to the rear part as shown in FIG. The storage state is set by rotating the frame a 'toward the upper surface of the machine frame a around the center.

This means moves the base end of the guide g to the position shown in FIG.

As described above, the bale discharging device in the wrapping machine A according to the present invention uses the bale support 1 provided on the machine frame a to start the packaging of the roll bale B.
Is released toward the rear of the machine frame a by rolling about its axis, the roll bale B is
The rider rides on a guide g which is provided so as to protrude rearward from the rear of the machine casing a and is offset in the left-right direction with respect to the position of the center of gravity G of the roll bale B.
Due to the rotation couple about the guide g due to its own weight, the roll bale B is turned and inverted to a posture in which the axis of the roll bale is in the vertical direction, and further, one of the circumferential surfaces of the roll bale B in the rotation direction. By grounding one end b,
The turning by the rotational couple is continued with the one end b as a fulcrum, and one end face in the axial direction is brought into contact with the ground, and the turning is completed and stabilized.
Can be turned around and released in a posture in which the axial center line direction is the vertical direction.

At this time, the operator who operates the wrapping machine A only needs to perform a normal discharging operation of pushing out the packed roll bale B from the bale support 1 toward the rear of the machine frame a. The operation is not troublesome, and the roll bale B is inverted by the guide g provided to be offset to one side in the axial direction with respect to the position of the center of gravity G of the roll bale B.
The mechanism is remarkably simple because the operation is performed using the weight of the apparatus itself.

Then, the released roll bale B is discharged even on an inclined ground because one end face in the axial direction is grounded and the other end face is the upper surface with the axial direction of the roll bale as the vertical direction. It is stable in position, and the other end surface that is the top surface is a portion where the number of wrapped plastic films f is large, so that when a bird stops there,
It is possible to prevent breakage due to leg claws and breakage caused by beaks, and also prevent permeation of rainwater from overlapping plastic films f.
