A battery 12 for supplying the power source and a cable take-up reel 29 described later are provided respectively.

As shown in FIG. 3, a laser measuring device 13 is provided which is located in front of or in the rear of the traveling direction of the carriage 3 to measure the distance to each carriage 3. These measurement signals are transmitted via a cable. Is input to the control unit 11. The laser length measuring device 13 is installed in the venue with its light emitting portion facing each trolley 3, and receives the reflected beam of the laser light to the trolley 3 to receive the trolley 3
Measure the distance to.

In the control unit 11, in addition to the relative control of the traveling speed of the carriage 3 and the rotation speed of the drum 1, the laser length measuring device 13 is used.
From the measurement signal of 1, the control for controlling the traveling speed of the trolley 3 is performed so that the trolleys 3 on the left and right proceed while keeping the same distance.

At the front and rear ends of the laid position of the artificial turf 2, as shown in FIGS. 4 to 6, a pit 14 for storing the truck 3 carrying the drum 1 is formed under the floor, and the stored items in the pit 14 are lifted. An elevating device 15 is provided. The lifting device 15 is formed from a base 16 on which the carriage 3 is mounted, a canopy 17 and its supporting pillars 18 that form the floor surface of the venue, into an open space in which the carriage 3 including the drum 1 can enter and exit on one side facing the venue. .

On the bottom surface of the pit 14, a plurality of screw rods 19 which vertically penetrate the substrate 16 are arranged.
A nut 20 that is screwed to 9 is fixed to the base 16. The screw rod 19 is located at the bottom of the pit 14 and has a gear box 21.
It is rotatably supported via the and is engaged with the worm gear 22 in the box 21. When each screw rod 19 rotates synchronously, the nut 20 advances and retracts according to the rotation direction of the screw rod 19, so that the base 16 horizontally moves in the pit 14 in the vertical direction.

The worm gear 22 is connected to a driving device (not shown) via a synchronous shaft 23, and when a lift-up operation is performed, the driving device rotates in the forward direction and the screw rod 19 causes the base 16 to face the upper surface of the venue. While raising it until it reaches the same height as the floor surface, when the lift down operation is performed, the drive device rotates in the opposite direction and the screw rod 19 causes the base plate 1 to rotate.

Since it rises to the same height as the above, the trolley 3 is lowered from the base 16 to the floor surface, and the terminal of the artificial turf 2 is fixed from the drum 1 to one side (venue side) of the pit 14.

When the traveling drive unit 4 and the drum rotation drive unit 10 are operated, the drum 1 rotates as the cart 3 advances so that the artificial grass 2 rolls on the installation surface. The artificial turf 2 is unrolled from the drum 1 for fixing the terminal, and is spread over the installation surface while being unfolded.

At this time, since the control unit 11 relatively controls the traveling speed of the carriage 3 and the rotation speed of the drum 1,
The degree of pulling of the artificial turf 2 at the time of unfolding and winding can be adjusted well. Further, since the trolley 3 advances while keeping the same distance as the laser length measuring device 13 on the basis of the command from the control unit 11, a deviation occurs in the developing direction of the artificial turf 2 or wrinkles occur when winding on the drum 1. There is no need to stop by.

When the trolley 3 reaches the other side of the installation surface, most of the artificial turf 2 can be unwound from the drum 1. After that, when the trolley 3 is placed on the lifting device 15 on the opposite side and lifted down, the artificial turf 2 is removed. It is fixed by the canopy 17 of the lifting device 15, and its terminal hangs on the bottom surface in the pit 14.

When removing the artificial turf 2, the artificial turf 2 should be completely wound by the drum 1 of the trolley 3 and stored in the original pit 14 in the reverse operation to the above. Can be efficiently processed in a short time by running and rotating the drum 1.

Since the underfloor pits 14 are provided on both sides of the venue, the trolley 3 can be stored efficiently without changing the traveling direction of the trolley 3 after the artificial grass 2 is installed and removed. After storage, the canopy 17 of the elevating device 15 constitutes the floor surface, so that effective use of space can be realized.

The elevating device 15 for the pit 14 is remotely operated from the management center of the venue, but in order to ensure safety during operation, foreign matter such as workers around the opening of the pit 14 (for example, within 1 m). When approaching, this is detected by laser or ultrasonic waves and an alarm is issued, and the lifting device 15
It is advisable to add a fail-safe function to stop the operation regardless of the remote operation of.

In this case, the sensor unit 31 has five proximity sensors a ₀ , b ₁ , b ₂ , c ₁ , c ₂ facing the floor surface at a predetermined detection distance m at fixed intervals n ₁ , n ₂ in the vehicle width direction. They are arranged side by side, and the control unit 11a controls the traveling speeds of the left and right carriages 3 based on these detection signals.

That is, when the trolley 3 is biased to the left side with respect to the detection piece 30 on the floor by the detection signals of the three sensors a ₀ , b ₁ and b ₂ arranged in the center of the sensor unit 31, the center sensor is detected. In addition to a ₀ , the sensor b _{2 on the} right side also senses the detection piece 30, so that the traveling direction of the carriage 3 is automatically corrected to the right until the output of the sensor b ₂ turns off, and the sensor unit 31 Sensors c ₁ and c located at both ends of
_{When 2} detects the detection piece 30, the rotation of the drum 1 is stopped together with the traveling of the carriage 3 as an abnormal state where automatic correction does not work.

According to this, the trolley 3 can be moved straight from one side of the venue to the other side along the detection piece 30 on the floor. In addition, since the laser length measuring device 13 is not used, it is possible to realize straight guidance of the carriage at low cost. The detection piece 30 and the sensor unit 31 on the floor may be provided on only one side of the carriage 3 at both ends of the drum 1. Also,
The sensor units 31 may be provided on at least one of the front and rear of the carriage 3 instead of being arranged on the front and rear of the carriage 3. Reference numeral 33 indicates a flooring material for the concrete floor 32.
