Abstract

PURPOSE:To contrive to perform baling operation in a shaft time by attaching plural twine-delivering devices for the baling to a frame parallelly in the direction of a roll-like bale in a bale-molding chamber so that the delivered twines are simultaneously wound on the periphery of the body of the bale. CONSTITUTION:A plurality of delivery devices b for delivering twines for baling to a roll-like bale B in a bale-molding chamber 4 are attached to a frame 1 parallelly in the axial direction of the roll-like bale B in the bale-molding chamber 14. The twines delivered from the plural delivery devices b, respectively, are simultaneously wound on plural baling-requiring sites on the peripheral surface of the body of the bale B, consequently shortening the time of the baling. The cost of the baling can be reduced because any mechanism for moving the delivery devices in the axial direction of the bale is not required.

Description

[Detailed Description of the Invention] [Industrial Application Field] This invention picks up grass that has been cut down in a field using a pickup device provided on the front side of the machine.
The bale is fed into a bale forming chamber installed at the rear of the machine, and formed into a roll bale by a roll-forming device installed in the bale forming chamber.Twine or tape is fed around the outer circumference of the bale from a twine feeding device. This invention relates to an improvement in a roll baler which wraps and packs bales, opens a bale forming chamber from this state, and releases the packed bales.

[Prior Art and Problems to be Solved by the Invention] In the above-mentioned roll baler, there are three types of packing means for packing the bale formed into a roll in the bale forming chamber.

The first method is to apply a twine (tying string) T, which is fed out from a twine feeding device, onto the circumferential surface of a roll-shaped bale B that is rotating in a bale forming chamber that is mounted on the body of a roll baler. As shown in Figure 1, the twine t is wound spirally around the body circumference of the bale B to package the bale B. In the room, a twine feeding device or a feeding guide that feeds the twine t to the roll-shaped bale B being rotated by the roll-forming device,
By moving the bale B sequentially in the axial direction, the bale B is wound spirally, so the twine t
There is a problem in that the roll-shaped bale B must be rotated several times in the bale forming chamber before being packed, which takes time.

The second means is to feed out a wide net corresponding to the axial width of the bale B from a feeding device to the bale B that has been formed into a roll shape in the bale forming chamber, and to roll out the bale B. This is a means of wrapping the circumferential surface of the trunk of the container with its wide net (n) as shown in Fig. 2.

Further, a third means is a net n in the second means.
Instead, a wide, non-stretchable sheet S is fed out from a feeding device and wrapped around the outer circumferential surface of the bale B as shown in FIG. 3.

However, this wide net) or wide sheet S,
What is the means for wrapping the veil B around its trunk?

Although the packaging time is shortened, there is a problem in that the cost of the wrapping net N or sheet S increases.

C. Means for Solving Problems] The present invention has been made to solve the problems that have arisen with such conventional means. In the bale forming chamber, the packing process involves packing the roll-shaped bale B from one end of the body circumferential surface of the rolled bale B to the other end in the axial direction.
The purpose of the present invention is to provide a new means for completing the process in a short time while packaging it using inexpensive thin tape or twine to prevent it from collapsing or deforming.

In the present invention, as a means for achieving the above-mentioned object, a feeding device that feeds out packing twine or tape to the circumferential surface of a roll-shaped bale formed in a bale forming chamber is used to form a bale forming chamber. A plurality of roll-shaped bales in the room are arranged in parallel along the axial direction and mounted on the body of the roll baler, and twine or tape is delivered from the feeding device to the axis of the bale circumferential surface of the bale in the bale forming chamber. A plurality of parts spaced apart in the axial direction of the bale's circumferential surface are each fed out at a predetermined interval in the direction, and the multiple parts spaced out in the axial direction on the circumferential surface of the bale are fed out in parallel in multiple series using twine or tape. Wrapping at once presents a means of packaging.

[Examples and effects] Next, embodiments of the present invention will be described in detail based on the drawings.

Roll baler A usually has the following characteristics as shown in Figure 4:

By driving each of the rollers 52 to rotate in the direction shown by the arrow in FIG. 6, the grass fed into the bale forming chamber 4 is This is a roller-type rolling-forming device (a) that rolls and compresses the material into a roll shape and forms it into a bale B.

In the third form, as shown in FIG. 7, a belt 54 is endlessly attached to guide rollers 53 arranged in a ring to surround the bale forming chamber 4 and supported on the machine body 1. This is a belt-type rolling-forming device a that forms grass into a roll-shaped bale B by winding the grass and rotating the belt 54 endlessly in the direction shown by the arrow in FIG. 7.

As described above, in the roll baler A, there are various configurations of the roll-forming device a that rolls and molds the grass fed into the bale-forming chamber 4 into the roll-shaped bale B. As an example, an example using a tight bar type rolling forming apparatus a shown in FIG. 5 will be described.

The feeding device is a twin t for packing as shown in Figure 10.
A brake 61 that applies a predetermined brake to the twine t pulled out from the twine bundle 60 in which the twine t is wound, a feed roll 62 that feeds out the twine t, and It consists of a rotating press roll 63 and a cutting mechanism 7 which is controlled to perform a cutting operation when the number of turns of the twine t that is fed out and wrapped around the body circumferential surface of the bale B reaches a predetermined number of turns.

Then, Volume 6 of the twine constituting the feeding device

The roll-shaped bales B formed in the bale forming chamber 4 are movably or fixedly supported in the axial direction in parallel in three speeds, and thereby the feeding devices b... As shown in FIG. 9, the bails B are arranged in parallel in three gears in the axial direction of the bail B and are installed on the fuselage l. In addition, in FIG. 10, 610 is y! which adjusts the brake pressure applied to the pulled out twine t as desired! 4! i screw, 61
1 is a spring whose spring pressure is changed by its adjustment screw 610;
Reference numeral 612 denotes a clamping piece that clamps the twine t being drawn out using the spring pressure.

The thus constructed embodiment device operates as follows.

When the roll-shaped bale B formed in the bale forming chamber a reaches a predetermined diameter and the detection mechanism that detects it is activated, the formed bale B is in a state to be packed. When the machine body 1 stops running, the feed roll 6 is started by driving a small starting motor that is connected to the shaft end of the feed roll 62 via a one-way clutch, or by manual operation.
2, and the unwinding end of the twine t is fed out by a length that reaches the grass that is picked up by the pickup device 2 and sent to the bale forming room 4. As a result, the unwinding end of the twine t is pulled out from the pickup device 2. It is picked up along with grass, etc. and sent to the bale forming chamber 4, where it enters the inside of the roll-shaped bale B that is being formed, and is thereafter rotated within the bale forming chamber 4 by the drive of the roll-forming device a. It is wrapped around the circumference of the body while being pulled by veil B.

Twine t pulled out by roll-shaped bale B
The brake 6 is applied in the feeding direction by the brake 6 that passes during the 1m movement, so this brake 6
1 and the roll-shaped bale B are wound around the trunk circumference of the roll-shaped bale B in a tensioned state between the starting position and wrapped around the trunk circumference of the roll-shaped bale B. When the number of turns wound on the circumferential surface of the trunk reaches a preset number of turns, the twine t is cut by the operation of the cutting mechanism 7 which is controlled to operate by mechanical or temporal means.

The terminal end of the twine t on the feeding side cut by the cutting mechanism 7 may be knotted using a knot M5m structure usually equipped on the roll baler, but the twine t is cut by the feeding roll 62 and the pressure roll 63. By disposing a coating device (not shown) such as a spray gun where the twine t is fed out, the adhesive or adhesive is applied to the twine t being fed out using this coating device. ,
The twine t that wraps around the circumferential surface of the bale B wraps around the circumferential surface of the bale B while maintaining tension.

In addition, the terminal end cut by the cutting mechanism 7 is adhered to the bale trunk circumferential surface without using a knotting mechanism, so that packaging is completed. At this time, when the Twine L is made of plastic, a heating device that enables thermal welding may be provided in place of the coating device. In this case, the heating device applies heat to melt the It may also be used as a cutting device 7 for cutting the twine t.

As a result, the two parallel feeding devices b...
As shown in FIG.
The packaging is completed by simultaneously bundling three parts of the circumferential surface of the trunk in the axial direction, the middle part and both ends.

Next, another embodiment will be shown with reference to FIGS. 11 to 13.

In this embodiment, a tape t° made of a stretchable plastic material is fed out to the bale B formed in the bale forming chamber 4, and a feeding device b is used to feed out the tape t'. This is an example in which there are two consecutive failures in which the bales B are arranged in parallel in the axial direction of the bale B, and the bales B are bound for packing only at both ends in the axial direction. Therefore, in place of the bundle 60 of twine t, the feeding device uses tape t.

A winding bundle 60 of is incorporated.

The bale B formed in the bale forming chamber 4 is equipped with a detection means for detecting that it has reached a predetermined diameter, and when starting the packing operation, the tip of the tape t' is picked up by the pick-up device W2. Conventionally known roll balers are equipped with a small motor or a manually operated driving means for driving the feeding roll 62 in order to feed the grass to a length that reaches the grass that is fed into the bale forming chamber 4. - is the same as -.

In addition, in this embodiment, in order to stretch the packing tape L' that is fed out from the feeding device, the circumferential speed of the feeding roll 62 and
This is done by providing a one-peripheral speed difference between the circumferential speed of the barrel surface of the bale B rotated by the roll-forming device a. Therefore, in this embodiment, there is no brake 61 in the previous embodiment, but instead the engulfing device a
A driving sprocket 500 that drives the tight chain 50 of
and the rotating shaft of the feed roll 62 through a transmission mechanism 65 such as a conduction chain, and due to the transmission by the transmission mechanism 65, the circumferential speed of the barrel circumferential surface of the bale B is lower than the circumferential speed of the feed roll 62. It is set so that it is faster. A clutch is provided within this transmission mechanism 65 to connect and disconnect power transmission. Further, the transmission mechanism 65 may be provided with a constant speed or variable speed mechanism. The clutch is also used to drive the 61-out roll 62 at the start of the packaging operation. Therefore, in this embodiment, a small motor for starting can be omitted.

The ratio between the circumferential speed of the roll-shaped bale B and the circumferential speed of the feeding roll 62, which is set by the conduction ratio of the transmission mechanism 65, is set so as to give optimum stretching to the extensible plastic tape t' to be fed out. Set to a preselected circumferential speed ratio. As a result, the tape t' made of a stretchable plastic material that is wound around the body circumferential surface of the bale B while being fed out by the rotation of the bale B is wound around the body circumferential surface of the rolled bale B between the feeding roll 62 and the tape t'. is stretched between the starting position and wrapped around the rolled bale B with high tension, and when the number of turns wrapped around the trunk reaches a predetermined number, it is activated. mechanical, or 1
By means of a cutting mechanism 7 controlled by temporal means,
As in the previous embodiment, the extensible plastic tape t' is cut and the tape t' is bonded by applying an adhesive or adhesive or by heat welding.

Next, still another embodiment will be shown in FIGS. 814 to 17.

This embodiment is a packing tape t that is fed out from a feeding device.
This is an example in which the stretching of the bale B is carried out between the delivery roll 62 and the circumferential surface of the bale B by applying a brake to the rotating shaft of the delivery roll 62. This is the same as the embodiment shown in FIGS. 11 to 13, that is, a stretchable plastic tape t' is used as a binding cord for packing the bale-formed bale B, and the tape is The tape bundle 60 of t'' is incorporated into the feeding device, and the tape t
There are two consecutive parallel failures of the feeding device that feeds out ``, and when the packing operation is started, a small motor or manual operation is activated.

This is the same as in the embodiments shown in FIGS. 11 to 13 above, in that the leading end of the tape t° is fed out long enough to reach the grass to be picked up by the pickup device 2.

However, there is no transmission mechanism that connects the rotating shaft of the a-out roll 62 and the drive sprocket 500 of the rolling forming device a.
A brake plate 66 is attached to the end of the rotating shaft of the feed roll 62, and a brake shoe 68 attached to a brake arm 67 is brought into pressure contact with this, thereby controlling the rotation of the feed roll 62. It is constructed to suppress What brake is applied to the rotating shaft of this delivery roll 62?

The ratio of the circumferential speed of the feed roll 62 to the circumferential speed of the rolled bale B is such that the stretchable plastic acid tape t'
The brake shoe 68 is adjusted to a preselected optimal circumferential speed ratio to provide optimal elongation for its composition.
Adjust and set the pressure contact force.

In this embodiment of the apparatus configured in this manner, the feeding roll 62 of the feeding device is driven by a small motor for starting or by manual operation, and the feeding end reaches the grass fed into the bale forming chamber 4. By letting out the tape t', it becomes wrapped around the body circumference of the bale B in the bale forming chamber 4,
Thereafter, the tape t° is drawn out and fed out by the rotation of the bale B, which is rotated by the drive of the first roll-forming device a, and is wound around the circumferential surface of the body of the bale B. At this time, the stretching curve of the tape t' , the winding of the tape t° around the body circumference of the roll-shaped bale B is carried out between the feed roll 62 and the body circumference of the roll-shaped bale B between the starting positions, so that the tape t° is wound around the body circumference of the roll-shaped bale B with high tension. follow.

As a result, when the number of turns of the tape t'' reaches a preset number, the cutting mechanism 7 controlled by mechanical or temporal means is activated to cut the extensible plastic. Cutting the acid tape t° and cutting the tape t that is fed out from the feeding roll 62 of the feeding device.
Apply adhesive or pressure-sensitive adhesive to the surface using a coating device such as a spray gun, or use a heating device capable of heat welding.
Packing is completed by gluing or welding the cut end of the tape t' on the feeding side to the outer circumferential surface of the tape t' that has been previously wrapped around the circumferential surface of the bale B. This is similar to the previous embodiment.

Next, other embodiments are shown in FIGS. 18 to 21.

This embodiment is a modification of the example shown in FIGS. 14 to 17 described above, in which the tape t' of the feeding device is used to stretch the extensible plastic tape t° from the feeding roll 62. This is an example in which this is done by applying a brake to the rotating shaft at the end 60 of the book, and the rest is the same as the previous embodiment.

That is, the packing operation is started by driving the feeding roll 62 of the feeding bag Mb by a small motor for starting or by manual operation so that the tape t' is fed by a predetermined length. After the tape t' is wrapped around the body circumference of the roll-shaped bale B in the bale forming chamber 4, the bale B itself, which is rotated by the drive of the roll-forming device a, pulls out the tape t'. This is similar to the previous embodiment in that the two feeding devices are installed in parallel, but the bundle 60 is wound with a stretchable plastic acid tape t'. By assembling a brake plate 66 on the shaft end of the rotating shaft and pressing a brake shoe 68 supported by a brake arm 67 onto this, a bundle 6 of stretchable plastic acid tape t° is created.
The tape t° is stretched by the rotational force of the bail B while suppressing the rotation of the tape t°.

The pre-key force that suppresses the rotation of the bundle 60 by the brake shoe 68 is such that the circumferential speed of the bundle 60 of the tape t° relative to the peripheral speed of the rolled bale B is the same as that of the extensible plastic tape t'. The peripheral speed ratio is adjusted to a preselected appropriate circumferential speed ratio in order to provide appropriate stretching according to the composition.

As a result, the stretchable plastic tape t' that is pulled and delivered by the roll-shaped bale B is 1
The winding of the bundle 60 and the roll-shaped bale B around the trunk circumferential surface is extended between the starting positions, and the bundle 60 is wound around the trunk circumference of the roll-shaped bale B with high tension.

When the number of turns of the tape t° wrapped around the barrel surface of the bale B reaches a preset number of turns, the cutting mechanism 7 controlled by mechanical or one-time means starts operating and the tape t ’ cut.

In addition, as mentioned above, the cut end of the tape t° is adhered to the outer periphery of the previously wrapped tape t'' by applying adhesive or adhesive, or by heat welding to complete the packaging work. This is similar to the embodiment.

Next, another embodiment will be shown with reference to FIGS. 22 to 24.

This embodiment is a modification of the embodiment shown in FIGS. 11 to 13, in which a stretching roll 90 and a feeding roll 62 are incorporated into a feeding device to stretch a stretchable plastic tape t' to be fed. This is an example in which the process is carried out using a pre-stretching device composed of
Since this embodiment is the same as the embodiment shown in FIGS. 11 to 13, the same reference numerals are given to the structural members having the same effect, and detailed explanation thereof will be omitted.

Thus, the pre-stretching device pivots the stretching roll 90 on the frame f, disposing the stretching roll 90 between the winding bundle 60 around which the stretchable plastic tape t° is wound and the feeding roll 62; And the rotation axis of the stretching roll 90 and the rotation axis of the feeding roll 62.

Electricity is transmitted through a transmission mechanism 91 consisting of a sprocket and a transmission chain that is passed around the sprocket, and the peripheral speed of the stretching roll 90 is controlled by the transmission ratio of the transmission mechanism 91 to the drawing roll 62.
The circumferential speed ratio is set so that it is slower than the circumferential speed. The transmission mechanism 91 may use another mechanical transmission mechanism, and the transmission mechanism 91 may include a transmission mechanism that changes the transmission ratio as desired.

The peripheral speed ratio of the feeding roll 62 and the stretching roll 90 is as follows.

The optimum circumferential speed ratio is preselected to provide the optimum pre-stretching for the composition of the extensible plastic tape t°.

Further, the feed roll 62 transmits its rotational axis to the axis of the drive sprocket 500 of the rolling forming device Na by a transmission mechanism 65 such as a transmission chain or other mechanical means,
A clutch is provided within the transmission mechanism 65 to interrupt transmission of power. The clutch incorporated in this transmission mechanism 65 is used to connect transmission when starting packing work. Further, the transmission mechanism 65 may be equipped with a constant speed or variable speed mechanism.

In the embodiment apparatus configured as described above, a stretchable plastic tape T' fed out from a one-volume bundle 60 is stretched between a stretching roll 90 and a feeding roll 62, and a rolled bale B is stretched between a stretching roll 90 and a feeding roll 62. The wrapping around the trunk circumferential surface of the rolled bale B is pulled between the starting positions and comes to be wrapped around the trunk circumferential surface of the roll-shaped bale B in a state with high tension. When the number of turns of the wound tape t' reaches a predetermined number, the cutting mechanism 7 controlled by mechanical or temporal means is activated, and the cut end of the tape t' is cut off. Tape t' that has been previously wrapped with adhesive or heat welding
This is similar to the embodiment described above, in that the packaging work is completed by adhering the material to the material.

Next, another embodiment will be shown with reference to FIGS. 25 to 27.

In this embodiment, a stretching roll 90 is incorporated in the &1 delivery device, and is transmitted through a transmission mechanism 91 to rotate at a circumferential speed with the delivery roll 62, thereby controlling the stretchability of the delivery roll 62. plastic tape with
゛、&! The fact that it has a built-in pre-stretching device for pre-stretching it before it is taken out is as shown in Figures 22 to 24 above.
Same as the example shown in the figure, but with the drive of the delivery roll 62.

The tape t° is pulled by the veil B rotated by the rolling forming device a, instead of being carried out by conduction with the driving sprocket 500 of the rolling forming device Na or other drive shaft, through the tape t′. This is an example of how this is done.

Therefore, in this embodiment, at the start of the packing operation, the feed rolls 62 of each feed device b... are placed in such a state that the tape t° reaches the grass that is picked up by the pickup device 2 and fed into the bale forming chamber 4. Until.

It is necessary to be able to drive it by a small motor for starting or by manual operation, and the transmission mechanism 65 that transmits the transmission between the rotation axis of the feed roll 62 and the rotation axis of the drive sprocket 500 of the rolling forming device a is required. The only difference from the embodiment shown in FIGS. 22 to 24 described above is the omitted points, and the rest of the configuration is the same as the embodiment described above.
and.

The same components will be designated by the same reference numerals and detailed explanations will be omitted.

In this embodiment, the dispensing end side of the stretchable plastic tape t' dispensed from the dispensing roll 62 of the dispensing device is wound around the circumferential surface of the bale B as shown in FIG. After that, the system operates in the same way as the previous embodiment.

That is, the extensible plastic tape t' to be fed out is pre-stretched by a pre-stretching device consisting of a 1 m roll 62 and a stretching roll 90, and the tape t'
is pulled by the roll-shaped bale B, and the winding of the roll-shaped bale B around the body circumferential surface is further stretched between the feeding roll 62 and the starting position, and the roll-shaped bale B is stretched with high tension. It comes to wrap around the body circumference of the veil B. It should be noted that when the number of turns of the tape t' reaches a predetermined number, the cutting mechanism 7 controlled by mechanical or temporal means is activated to cut the tape t'. Alternatively, the end of the tape t' is adhered to the previously wound tape t' by thermal welding, and the packaging operation is completed, which is the same as in the previous embodiment.

Next, a further different embodiment is shown in FIGS. 28 to 31.

In this embodiment, the rolled bale B in the bale forming chamber 4 is
The bale B is packed using a non-stretchable tape, which is fed out from multiple feeders Mb arranged in parallel, and is wrapped at multiple points in the axial direction on the circumferential surface of the bale B at once. This is an example.

Since the structure of the apparatus itself is the same as the embodiment shown in FIGS. 14 to 17 described above, the same reference numerals are given to constituent members having the same effect, and detailed explanation thereof will be omitted.

In this embodiment, the feeding end of the tape C is brought into contact with the circumferential surface of the bale B as shown in FIG. After the tape C is wound, the tape C is pulled out by the rotation of the bale B, which causes the feed roll 62 to rotate and the tape t' to be fed out from the feed device. At this time, the rotation of the delivery roll 62 is suppressed by the brake shoe 68 provided on the brake arm 67 coming into pressure contact with the brake plate 66 provided on the rotation axis of the delivery roll 62. The tape C without the tape is connected to the feeding roll 62 and the rolled bale B
When wrapped around the trunk circumferential surface of the rolled bale B, a tension is maintained between the starting position and the bale B, which is maintained in this state, and continues to be wound around the trunk circumferential surface of the roll-shaped bale B. As a result, when the number of turns of the tape C fed out from each feeding device and wound around the body circumference of the bale B reaches a predetermined number, the cutting mechanism 7 controlled by mechanical or temporal means is activated. The cutting operation is performed, and the end of the cut tape C is adhered to the circumferential surface of the previously wrapped tape C using adhesive or heat welding, thereby completing the packaging operation. This is similar to the previous embodiment.

Note that the adhesive or pressure-sensitive adhesive is applied to the tape C that is being fed out by applying the adhesive or pressure-sensitive adhesive to the tape C that is being rolled out under tension.
Ensures that the dog maintains tension when wrapped around the dog. In addition, if the tape is made of plastic, by using a means to cut the non-stretchable tape while applying heat instead of the cutting mechanism 7, welding to the previously wound non-stretchable tape can be simultaneously performed. Be able to do it.

Still another embodiment is shown in FIGS. 32 to 35.

In this embodiment, the tape t° used for packaging is different from the embodiment shown in FIGS. 18 to 21.

This is an example in which a non-stretchable tape is used instead, and the only difference is that the tape wound around the bundle 60 of the feeding device is a non-stretchable tape. Since this is the same as the embodiment shown in FIGS. 18 to 21, the same reference numerals are given to constituent members having the same effect, and detailed explanation thereof will be omitted.

Therefore, in this embodiment, the tension applied to the tape that is fed out from the feeding roll 62 of each feeding device and wrapped around a plurality of locations in the axial direction of the trunk circumferential surface of the bale B at once is a non-stretchable tape. A brake shoe 68 provided on a brake arm 67 is pressed against a brake plate 66 provided on the rotating shaft of the bundle 60 in which the tape is wound, thereby suppressing the rotation of the bundle 60. This is done by pulling out the tape.

That is, the non-stretchable tape pulled out by the roll-shaped bale B is taut between the bundle 60 in which it is wound and the starting position of the roll-shaped bale B when it is wrapped around the body circumference. The cutting mechanism 7 of the wrapped tape, which becomes under tension and wraps around the body circumference of the rolled bale B, and the completion of binding by adhesion or welding are the same as in the above-mentioned embodiment. The same is true.

In addition, in the case of a tape with no adhesiveness and no extensibility, the wrapping of this tape is carried out between the i&out roll 62 and the pressure roll 6.
By applying an adhesive to the tape t'' that is fed out by 3 and 3, it becomes able to maintain tension and wrap around the body circumference of the roll-shaped bale B. If the tape C is made of plastic acid, a heating device that enables heat welding is used instead of the cutting mechanism 7 to cut the non-stretchable tape by heat melting, so that it can be heat welded to the previously wound tape C at the same time. Be able to do it.

[Effects of the Invention] As explained above, the present invention forms agricultural harvests such as grass into roll-shaped bales using a roll baler, and then feeds the rolled bales from a feeding device in the bale forming chamber of the roll baler. When packing by binding the circumferential surface of the trunk using non-stretchable tape or stretchable plastic acid tape, the twine or tape feeder 11 is placed in a rolled form in the bale forming chamber. Multiple tapes or twines are mounted in parallel along the axial direction of the bale, and each tape or twine is fed out from a plurality of feeding devices arranged in parallel to multiple locations on the circumferential surface of the bale that are required for packaging.
Since packaging is done by wrapping and tying all at once, packaging by wrapping tape or twine around the necessary parts can move the feeding device in the axial direction of the bale. In addition, the time required to wrap the tape or twine around one point in the axial direction of the bale's circumferential surface can be used to bind multiple points necessary for packaging. For this reason, the packaging time is short, and a mechanism for moving the feeding device in the axial direction of the bale is not required, so that costs can be reduced.

In addition, if adhesive and stretchable plastic acid tape is used to wrap the rolled bale B at multiple points necessary for packaging, This allows the stretchable plastic acid tape to remain stretched and wrap around the body of the bale, and the cut end of the tape wraps around the previously wrapped stretchable plastic acid tape. By sticking to the tape, it will maintain its wrapped state under high tension, so even if the volume of the bale of grass etc. decreases over time, the rolled bale will remain intact. This makes it possible to minimize collapse and deformation of the structure.
