An example of the artificial grass wrapping device 40 is configured by the above 41 to 86.

The operation of winding the artificial grass 89 laid on the ground 90 in the above embodiment will be described below. (A) Removing the core 88 This is performed manually or by a forklift. For example, the core 88 stored in the storage location (storage warehouse) is taken out by transportation and the artificial turf 89 to be wound is taken. Located in the end part. In this case, the aluminum winding core 88 can be lightened and can be easily and quickly handled. (B) Setting of the winding core 88 on the artificial turf 89 This is done manually, and by winding the end portion of the artificial turf 89 around the winding core 88 two or three times as shown by the phantom line in FIG. The winding core 88 can be set (mounted) on the artificial turf 89. (C) Picking up the winding core 88 by the artificial turf winding device 40 First, it is confirmed whether or not the center of the artificial turf winding device 40 is located at the center of the artificial turf 89 in the width direction. When the center is deviated, the side shift cylinder 46 is expanded and contracted by operating the side shift lever 31, and the both booms 43 are integrally moved left and right to align the centers. Before and after this, as shown in FIG. 5, the push-pull body 54 is pulled and moved through the operation portion 58, and the core holding body 62 is moved to the boom 43 side and positioned inside the stopper device 70. In this state, the artificial turf winding device 40 is moved forward together with the main body 1, and both booms 43 are moved downward to move the core holder 62.
Is made to face the end of the winding core 88 from the outside.

Then, the push-pull body 5 is operated through the operating portion 58.
4 is pushed to move the core holding body 62 to the side away from the boom 43, and is fitted into the end portion of the core 88 as shown in FIG. At this time, the pushing / pulling body 54 is pushed and moved by allowing the penetrating portion 60 to pass through the contact plate 57 including the locked portion 57a, so that the contact plate 57 is positioned inside the locking body 59. . After that, the push / pull body 54 is rotated through the operation portion 58, and the contact plate 57 is rotated in a 90 ° shape together with the push / pull body 54, thereby changing the relative position of the locked portion 57 a with respect to the penetrating portion 60. As a result, the pull-out movement of the locked portion 57a can be prevented (removed) by the locking body 59.

The push / pull body 54 is operated via the operating portion 58.
When the push-pull body 54 and the winding core 88 are displaced for some reason when the push-pull body is pushed (pushed in), the rubber body 66 on the push-pull body 54 side is brought into contact with the end surface of the winding core 88. This can prevent the end face from being damaged.

In this way, the tension switch 36 is turned on while the core 88 is held and locked via the core holding means 50 between the free ends of the boom 43.
As a result, the tension cylinder 86 is automatically extended and the tension arm 82 is swung downward (closed) to bring the contact roll 83 into contact with the roll-shaped artificial grass 89a wound around the winding core 88 from above. Thus, the roll-shaped artificial grass 89a can be prevented from being loosened. After that, the boom lifting cylinder 45 is extended by operating the operation lever 31, and both booms 43 are integrally swung upward (raised), whereby the winding core 88 can be lifted, and thus the pickup of the winding core 88 can be performed. You can do it. (D) Winding of the artificial grass 89 by the artificial grass winding device 40 First, the roll rotation lever 32 is operated to the winding side. At this time, the winding motor 85 does not rotate in a relieved state because the artificial turf 89 has a large tension. Next, the artificial grass wrapping device 40 is moved forward together with the main body 1 to wind up the artificial grass 89. That is, by moving forward, the artificial grass 8
9, the contact roll 83, which is forcibly rotated by the winding motor 85, is in contact with the artificial turf 89 at this time, so that the artificial turf 89 is rotated together with the winding core 88, so that the solid line in FIG. The artificial grass 89 is wound up as shown in FIG.

In the two core holding means 50, the core holder 62 is moved relative to the push / pull body 54 by the rotation of the core 88.
Is driven to rotate. When the winding core 88 is about to laterally shift, the lateral shift movement can be blocked by the stopper device 70. That is, when the winding core 88 is about to be laterally displaced, the end surface of the winding core 88 is brought into contact with the stopper portion 74,
As the winding core 88 rotates, the stopper body 72 rotates around the horizontal axis 65 (i.e., rotates around), so that the end surface of the winding core 88 and the stopper portion 74 are slidably contacted with each other. Therefore, it is possible to prevent lateral deviation of the winding core 88 without damaging the both 88 and 74, that is, while protecting the winding core 88 made of aluminum.

At this time, when the stopper portion 74 is made of MC nylon resin, it is possible to more effectively prevent scratches at the time of contact. When the stopper body 72 is of a fixed type, the stopper section 74 made of MC nylon resin is easily worn away and the end face of the winding core 88 is also damaged. 74 is less worn and the end face of the winding core 88 is less likely to be damaged. (E) Artificial turf winding device 40 rolled artificial turf 89a
When the winding of the main body 1 is completed,
The roll-shaped artificial grass 89a is transported to the storage location. And
First, by operating the operation lever 31, the boom raising / lowering cylinder 45 is contracted, and the booms 43 are integrally swung downward (downward), thereby landing the roll-shaped artificial turf 89a that is lowered together with the winding core 88. Next, by operating the tension arm raising switch 30, the tension cylinder 86 is contracted, and the tension arm 82 is swung (opened) upward to separate the contact roll 83 upward from the roll-shaped artificial turf 89a.

Before and after this, the push-pull body 54 is rotated through the operating portion 58, and the push-pull body 54 and the contact plate 57 are rotated.
Is rotated 90 degrees so that the contact plate 57 with respect to the penetrating portion 60 is positioned to allow passage including the locked portion 57a. Next, the push / pull body 54 is pulled and moved via the operation portion 58 to move the core holding body 62 to the boom 43 side, so that the core 88 is pulled out from the end of the core 88 as shown in FIG.

As a result, the artificial grass winding device 40 can be removed from the roll-shaped artificial grass 89a. That is, the winding core 88 can be reset (disengaged) from between the booms 43 by a simple and easy operation of only pulling and moving the push-pull body 54. Then, the main body 1 is moved backward to return to the step (A) described above.

Through the above steps (A) to (E), the artificial grass 89 can be wound by synchronous winding while the rolled artificial grass 89a is floating. The ground 90
The work of laying the artificial grass 89 on the top can be performed in the same manner as described above.

That is, the core holders 62 are fitted into both ends of the core 88 of the roll-shaped artificial grass 89a. Next, the tension switch 36 is turned on, and the tension arm 82 is swung downward (closed) to contact the contact roll 83.
Is contacted with the roll-shaped artificial grass 89a to prevent loosening.
Then, by swinging (raising) both booms 43 integrally and lifting the winding core 88, the roll-shaped artificial grass 89a can be set in the artificial grass winding device 40.

In this state, the main body 1 is run to carry the rolled artificial grass 89a to the laying start position. Then, the roll rotation lever 32 is operated to the rewind side to rewind the tip of the roll-shaped artificial grass 89a to the laying start position, and then the roll rotation lever 32 is returned to the neutral position to stop the rotation of the roll. Next, the tip of the roll-shaped artificial grass 89a is pressed so as not to be displaced even if it is pulled, and the artificial grass wrapping device 40 is moved backward together with the main body 1 to make the artificial grass 8
Rewind 9 and lay it down.

At this time, the contact roll 83 can rotate freely, and the contact roll 83 rotates by rewinding the roll-shaped artificial grass 89a.
Further, although the outer diameter of the roll-shaped artificial grass 89a becomes smaller, the contact roll 83 follows so as not to loosen.

After the laying is completed, first the both booms 43
The core 88 is landed by integrally swinging (lowering). Next, the tension arm 82 is swung upward (opened) to raise the contact roll 83.
Then, the push / pull body 54 is pulled and moved via the operation portion 58, and the core holding body 62 is moved to the boom 43 side, so that the core 88 is pulled out from the end portion thereof, as shown in FIG. As a result, the winding core 88 is attached to the artificial turf winding device 40.
Can be removed.

In the embodiment described above, the push / pull body 54
Pushing and pulling are performed manually via the operation unit 58, but this may be performed mechanically such as by operating a cylinder device provided on the boom 43 side.

Although the aluminum core 88 is used in the above embodiment, a core made of reinforced resin or other metal such as iron may be used.
