  The rotation speed of the winding motor 55 is adjustable, and does not rotate when the tension of the artificial turf 72 is large so that synchronous winding can be performed. When the artificial turf 72 is loosened by the reverse movement and the tension is reduced, the winding motor 55 is rotated and can be wound up by the reverse movement (traveling).

Hereinafter, in the first embodiment described above, an operation of winding the artificial grass 72 laid on the ground 73 will be described.
(A) Setting the core 71 on the artificial turf 72 This is done manually. After winding the end of the artificial turf 72 two or three times around the core 71, the mandrel 70 is attached to both ends of the core 71. The core 71 can be set on the artificial turf 72 by inserting and connecting the insertion portion 70b.
(B) Pickup of the winding core 71 by the artificial grass winding device 30 First, it is confirmed whether or not the center of the artificial grass winding device 30 is located at the center of the artificial grass 72 in the width direction. When the center is deviated, the side shift cylinder 39 is expanded and contracted by operating the side shift lever 25, and both the booms 33 are integrally moved left and right to align the centers.

Can be done.
(C) Winding the winding core 71 by the artificial turf winding apparatus 30 First, the winding speed is adjusted by the speed adjustment dial of the winding motor 55. At this time, the winding motor 55 does not rotate because the tension of the artificial grass 72 is large. Next, the artificial turf winding device 30 is moved backward together with the main body 1 to wind up the artificial turf 72. That is, the artificial turf 72 is loosened by moving backward, and at this time, the contact roll 53 forcedly rotated by the winding motor 55 is in contact with the artificial turf 72 so that the artificial turf 72 rotates together with the core 71. Thus, the artificial turf 72 is wound up. In the mandrel 70, the insertion portion 70b is rotated together with the core 71.

As described above, when the artificial turf winding apparatus 30 is moved backward together with the main body 1 and the artificial turf 72 is wound up, the dimension e between the outer surfaces of the rear wheels 19 is narrower than the width E of the artificial turf 72.

First, the lock member 45 is unlocked and swung upward, and the hook member 42 is moved upward to open the concave portion 41. Next, the boom raising / lowering cylinder 36 is contracted by the operation of the boom raising / lowering lever 26, and both the booms 33 are integrally swung downward (lowered), thereby landing the roll-shaped artificial turf 72 a lowered together with the winding core 71. Can do.

  Then, the tension cylinder 56 is contracted by the operation of the tension arm opening / closing lever 24, the tension arm 52 is swung upward (opened), and the contact roll 53 is separated upward from the roll-shaped artificial grass 72a. By moving the main body 1 forward in this state, the artificial grass winding device 30 can be removed from the roll-shaped artificial grass 72a. Thereafter, the mandrel 70 is pulled out from both ends of the core 71, thereby returning to the step (A) described above.

Hereinafter, in the first embodiment described above, an operation of laying the artificial grass 72 on the ground 73 will be described.
(E) Set of roll-shaped artificial turf 72a with respect to artificial grass wrapping apparatus 30 First, the mandrel 70 is inserted into both ends of the core 71 in the roll-shaped artificial turf 72a, and the insertion portions 70b are inserted and connected. Next, it is confirmed whether or not the center of the artificial grass winding device 30 is located at the center of the roll-shaped artificial grass 72a in the width direction. When the center is shifted, the side shift lever 25 is operated to operate the side shift. By extending and retracting the cylinder 39, the booms 33 are moved to the left and right together to align the center. Before and after this, the locking member 45 is released and swung upward, and the hook member 42 is moved upward to open the concave portion 41. Then, by operating the tension arm opening / closing lever 24, the tension cylinder 56 is contracted, the tension arm 52 is swung upward (opened), and the contact roll 53 is separated upward.

In this state, the artificial grass winding device 30 is moved backward together with the main body 1, and the recessed portion 41 is locked to the held portion 70 c of the mandrel 70. Next, the boom raising / lowering cylinder 36 is extended by the operation of the boom raising / lowering lever 26, and both the booms 33 are integrally swung upward (raised), whereby the winding core 71 can be lifted, and the roll-shaped artificial grass 72a Can be picked up. Thereafter, the hook member 42 is closed downward, the lock member 45 is swung downward and locked to the locking step 44, whereby the core 71 is moved between the booms 33 via the mandrel holding device 40. The roll-shaped artificial turf 72a can be set in the artificial turf winding apparatus 30.
(F) Installation of artificial grass 72 by artificial grass winding device 30 When the setting is completed, the roll 1 is transported to the start position by moving the main body 1 or the like. Then, the boom elevating cylinder 36 is automatically contracted, and both the booms 33 are integrally swung downward (lowered) to ground the roll-shaped artificial grass 72 a that is lowered together with the core 71. Next, by setting the winding direction switch to the laying side, the tension cylinder 56 is automatically extended, the tension arm 52 is swung downward (closed), and the contact roll 53 is moved upward to the roll-shaped artificial grass 72a. Abut. Thereby, loosening of the roll-shaped artificial grass 72a can be prevented.

  In this state, the artificial grass winding device 30 is moved forward together with the main body 1 and the artificial grass 72 is laid while being rewound. At this time, the contact roll 53 that is forcibly rotated reversely by the winding motor 55 is in contact with the roll-shaped artificial turf 72 a, so that the roll-shaped artificial turf 72 a is rotated together with the winding core 71, thereby 72 is rewound.

As described above, when the artificial turf winding apparatus 30 is advanced together with the main body 1 to lay the artificial turf 72, the dimension e between the outer surfaces of the rear wheels 19 is narrower than the width E of the artificial turf 72. The rear wheel 19 always travels on the ground 73 before the artificial turf 72 is laid. Therefore, there is no possibility that the artificial turf 73 is damaged by the load on the artificial turf winding machine side, and further, the main body 1, that is, the artificial turf winding apparatus 30, does not tilt up and down in the left-right direction. Work accurately.
