1 and 2, reference numeral 1 denotes a drum (core material) for winding an artificial turf 2 around a roll, and carts 3 are provided at both ends thereof. The bogie 3 includes driving wheels 3a and driven wheels 3b on the front and rear sides, and when the driving wheels 3a receive a rotational force from the driving unit 4 for traveling, they run at a low speed. The rotating shaft 5 of the drum 1 is mounted on the carriage 3
A self-aligning ball bearing block 6 that supports the (shaft) is provided.

The drum 1 is formed by arranging a large number of cylindrical members 1a coaxially and adding together by connecting bolts 7. These cylindrical members 1a are integrally supported by a rotating shaft 5 penetrating the shaft core, and are rotatably mounted at both ends thereof via a bearing block 6 of the bogie 3.

In order to prevent the carriage 3 from tilting due to the lateral load even when the rotating shaft 5 of the drum 1 is bent by the weight of the artificial turf 2, the bearing block 6 can swing freely to the left and right of the carriage 3 by the pin joint 8. It is placed on the movable receiving table 9. The artificial turf 2 is formed in such a manner that a standard product produced in a strip shape having a width of several meters is juxtaposed and joined, so that the installation area of a venue such as an indoor stadium can be covered by one sheet.

The truck 3 has a drum rotation drive unit 10 for applying a rotational force to the drum 1, a control unit 11 for relatively controlling the rotation speed and the speed of the carriage 3, and a drive unit 4, 10. And a winding reel 29 for a cable to be described later.

As shown in FIG. 3, there is provided a laser length measuring device 13 which is located in front of or behind the traveling direction of the carriage 3 and measures the distance from 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 part directed toward each truck 3, receives the reflected beam of the laser beam to the truck 3, and
Measure the distance to

The controller 11 controls the traveling speed of the carriage 3 and the rotation speed of the drum 1 in addition to the relative control.
From the measurement signal, control is performed to control the traveling speed of the bogie 3 so that the left and right bogies 3 travel while maintaining the same distance.

As shown in FIGS. 4 to 6, pits 14 for storing the cart 3 on which the drum 1 is mounted are formed under the floor at the front and rear ends of the laying position of the artificial turf 2, and the contents in the pits 14 are lifted. The lifting device 15 is provided. The lifting device 15 is formed from a base 16 on which the cart 3 is mounted, a canopy 17 and a support column 18 constituting the floor of the venue, and an open space where the cart 3 including the drum 1 can enter and exit on one side facing the venue. .

A plurality of screw rods 19 vertically penetrating the base 16 are arranged on the bottom surface of the pit 14.
A nut 20 screwed to the base 9 is fixed to the base 16. The screw rod 19 is mounted on the gearbox 21 at the bottom of the pit 14.
And is rotatably supported via a worm gear 22 in the box 21. When each screw rod 19 rotates synchronously, the nut 20 advances and retreats in accordance with the rotation direction of the screw rod 19, so that the base 16 moves horizontally in the pit 14 in the vertical direction.

The worm gear 22 is connected to a drive (not shown) via a synchronous shaft 23. When a lift-up operation is performed, the drive rotates in the forward direction, and the screw rod 19 moves the base 16 to the upper surface of the venue. When the lift device is lifted up while reaching the same height as the floor, the driving device rotates in the opposite direction and the screw rod 19 rotates the base 1.
6 is lowered until the canopy 17 coincides with the floor of the venue.

In order to prevent the base 16 from swaying, guides 24 extending vertically on both side walls in the pit 14 are provided on both sides of the base 16 with leg plates 25 (base 1) corresponding to the respective guides 24.
6), which also functions to regulate the lift-down position. The elevating device 15 is remotely operated from a management center (not shown) in the venue.

The operation based on such a configuration will be described.
When the artificial turf 2 is installed in the venue, the lifting device 15 is lifted up. When the cart 3 from the pit 14 (the artificial turf 2 is wound around the drum 1 is loaded), the base 16 is placed on the floor of the venue. The truck 3 is lowered from the base 16 to the floor, and the terminal of the artificial turf 2 is fixed from the drum 1 to one side (the venue side) of the pit 14.

When the driving unit 4 for driving and the driving unit 10 for rotating the drum are operated, the drum 1 rotates so as to roll the artificial turf 2 on the installation surface as the carriage 3 advances. The artificial turf 2 is pulled out from the drum 1 for fixing the terminal, and is spread while being spread on the installation surface.

At this time, since the control unit 11 relatively controls the traveling speed of the truck 3 and the rotation speed of the drum 1,
The tension at the time of unfolding and winding of the artificial turf 2 can be adjusted well. In addition, the cart 3 travels while maintaining the same distance as the laser length measuring device 13 based on the command from the control unit 11, so that a deviation occurs in the developing direction of the artificial turf 2 or wrinkles occur when the artificial turf 2 is wound on the drum 1. There is no need to drop.

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

When the artificial turf 2 is removed, the artificial turf 2 is completely wound by the drum 1 of the bogie 3 and stored in the original pit 14 by the reverse operation, and the work is also performed by the bogie 3 And the rotation of the drum 1, the processing can be efficiently performed in a short time.

Since the pits 14 are provided under the floor 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 turf 2 is installed and removed. After storage, the canopy 17 of the elevating device 15 forms a floor surface, so that effective use of space can be realized.

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

FIGS. 7 and 8 show a configuration in place of the laser length measuring device 13 for guiding the carriage 3 to travel straight.
On the floor of the venue, a detection piece 30 extending in the straight traveling direction of the bogie 3 is provided.
Sensor units 31 that detect the detection pieces 30 on the floor are provided before and after the cart 3. In this case, the sensor unit 31 sets five proximity sensors a ₀ , b ₁ , b ₂ , c ₁ , c ₂ facing the floor at a predetermined detection distance m at fixed intervals n ₁ , n ₂ in the vehicle width direction. The control unit 11a controls the running speed of the left and right carriages 3 based on these detection signals.

That is, if the bogie 3 is deflected to the left with respect to the detection piece 30 on the floor surface based on the detection signals of the three sensors a ₀ , b ₁ , b ₂ arranged in the center of the sensor unit 31, In addition to a ₀ , the sensor b _{2 on the} right side also senses the detection piece 30, so that the control to automatically correct the traveling direction of the bogie 3 to the right until the output of the sensor b ₂ is turned off, and the sensor unit 31 Sensors c ₁ and c located at both ends of
_{When the} sensor ₂ detects the detection piece 30, the rotation of the drum 1 is stopped along with the movement of the carriage 3 as an abnormal state where the automatic correction is not effective.

According to this, the carriage 3 can be moved straight from the one side of the venue to the opposite side along the detection piece 30 on the floor surface. In addition, since the laser length measuring device 13 is not used, it is possible to realize the direct guidance of the bogie 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 unit 31 may be provided on at least one of them, instead of being arranged before and after the cart 3. Reference numeral 33 denotes a flooring material for the concrete floor 32.
