DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for winding artificial turf laid on the floor of an indoor sports facility.

[0002]

2. Description of the Related Art Athletics stadiums laid with artificial turf as typified by baseball stadiums have been increasing, but this trend has also spread to sports facilities such as gymnasiums and indoor stadiums, or multipurpose halls. However, in such facilities, winding or laying artificial turf is performed depending on the type of competition or event in order to increase the operation rate.

As an apparatus for winding an artificial turf laid on a floor or the like or laying the wound artificial turf, for example, a device disclosed in US Pat. No. 4,399,954 has been put to practical use. ing. In this device, one end of the artificial turf is fixed to a winding drum, and the lower front and rear sides in a direction orthogonal to the axis of the winding drum are supported by a pair of front and rear receiving rollers. The artificial turf is wound up by being supported by a pair of front and rear support rollers and rotating a receiving roller by a motor.

[0004]

Generally, an artificial turf formed so as to be able to be wound has a synthetic resin pile planted on a rubber base so as to be easily bent and wound. The back surface of the base is formed in a flat shape without unevenness so as not to rattle. On the other hand, in the above-mentioned technology, when the artificial turf is wound with the pile inside, the artificial turf is pulled in by the frictional force between the back surface of the base and the surface of the receiving roller, and is wound on the winding drum. . That is, the base is made of rubber and has no irregularities on the back surface, and the receiving roller is also usually formed in a simple cylindrical shape, so that the base and the receiving roller slip easily,
This phenomenon is remarkable at the start of winding. It is conceivable to wind up the pile of the artificial turf outside, but at this time, the artificial turf and the receiving roller further slide. That is, the above-mentioned technology winds up the artificial turf by the frictional force between the pile of the artificial turf or its base and the receiving roller. There are problems such as wrinkling and damage of artificial turf due to.

[0005] In addition, artificial turf tends to meander easily during operation due to various conditions such as habit and floor condition, but the above-mentioned technology has no special mechanism for correcting meandering, so there is a great hindrance to safe driving. .

Accordingly, an object of the present invention is to provide an artificial turf winding device capable of reliably and accurately winding an artificial turf.

[0007]

In order to achieve the above-mentioned object, in the present invention, the winding shaft to which one end of the artificial turf is fixed, and the lower front and rear sides in a direction perpendicular to the axis of the winding shaft are provided. A pair of front and rear receiving rollers to be supported, and a pair of front and rear supporting rollers for respectively supporting the front and rear lower sides in a direction orthogonal to the axis at a plurality of locations in the axial direction of each receiving roller, and rotating the receiving rollers when winding the artificial turf Receiving roller driving device,
A floating device for floating the artificial turf when the receiving roller rotates,
A technical means of having a meanderable centering roller which can be moved up and down and which is brought into contact with a bent portion of the artificial turf from the laying surface of the artificial turf to the winding shaft is adopted.

In the present invention, a winch is installed at the end of the artificial grass laying surface on the same side as the winding shaft, the winch is connected to the tip of the artificial grass with a rope, and the winch is artificially driven with the winch while driving the receiving roller. You may draw grass.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a plan view of a stadium provided with an artificial turf winding device according to one embodiment of the present invention, FIG. 2 is a cross-sectional view taken along line AA of FIG. 1, FIG. FIG. 4 is an enlarged view of a portion C in FIG. As shown in FIG. 1, a pit 1 is formed at one end (left side in the drawing) of the stadium, and the opening of the pit 1 is closed with an openable / closable lid 1a (see FIG. 2). An artificial turf winding device 4 for winding the artificial turf 3 laid on the surface 2 is provided. The artificial turf winding device 4
Also serves as a device for laying the artificial grass 3 on the floor 2.

As shown in FIG. 2, the artificial turf winding device 4 includes:
It has a plurality of corner rollers 5 provided at the entrance of the pit 1 so as to be able to move up and down. Both ends of each corner roller 5 are pivotally supported on the upper part of a cylinder 6 supported on the inner wall of the pit 1. When winding (laying) the artificial turf 3, the desired pits are pushed up by pushing up the desired corner roller 5. The sliding resistance of the artificial turf at the entrance is reduced, and when the center of the artificial turf 3 is displaced, the meandering roller is tilted to correct the meandering. As the cylinder 6, various cylinders such as a motor cylinder, a hydraulic cylinder, and a pneumatic cylinder can be used.

One end of the artificial turf 3 passing through the corner roller 5 is
It is fixed to the winding shaft 7. Since the winding shaft 7 has an axial length slightly larger than the width of the artificial turf 3, and when all the artificial turf 3 laid on the floor 2 is wound, the gravity becomes extremely large. It is not practical to support only at both ends. Therefore, in the present invention, the take-up shaft 7 is supported by a pair of front and rear receiving rollers 8a and 8b provided below the front and rear thereof, and each of the receiving rollers 8a and 8b is supported by a pair of front and rear supporting rollers at several positions in the axial direction. It is supported by roller pairs 9a and 9b. Driving motors 10a and 10b are arranged on both left and right ends of each of the receiving rollers 8a and 8b (see FIG. 1). These drive motors 10a, 10b
Are driven synchronously, and the receiving rollers 8a and 8b are rotationally driven via the chains 11a and 11b (see FIG. 3).

At the bottom of the pit 1, a plurality of winches 13 for winding a rope 12 connected to the artificial turf 3 are provided at predetermined intervals. As shown in FIG. 4, one end (hook portion 12a) of the rope 12 has a pile (for example, nylon) 3c planted on a base cloth (for example, polyester) 3b fixed on a base (for example, foamed polyethylene) 3a. Metal fitting 14 fixed to the tip of artificial turf 3 (slippery material (for example, MC nylon) on the back surface)
Is fixed to the artificial turf 3 via a hook 15 fixed thereto. As shown in FIG. 2, the other end of the rope 12 is connected to a rope sheave 16 supported on the back of the lid 1 a and the upper part of the pit 1.
Is fixed to the winch 13.

The operation according to the above configuration is as follows.
The laying operation of the artificial turf can be performed, for example, in the following procedure. After the lid 1a is opened, rope sheaves 16 (see FIG. 1) are installed at a plurality of locations on the end surface of the floor 2 opposite to the pit 1, and attached to the tip of the rope 12 held on the back surface of the lid 1a. The hook portion 12a (see FIG. 4) is pulled out in the direction of the arrow X in FIG. 2, and the hook 1 fixed to the metal fitting 14 fixed to the tip of the artificial turf 3 after passing through the rope sheave.
Lock to 5. Next, by driving the motors 10a and 10b and rotating the receiving rollers 9a and 9b in the direction of the arrow shown in the figure, driving the winch 13 and winding the rope 12 (pulling in the direction of the arrow X in the figure), the artificial grass 3 Winding shaft 7
And is laid on the floor 2. After all the artificial grass 3 is laid on the floor 2, the rope 12 is removed from the hook at the tip of the artificial grass 3, only the rope 12 is wound around the winch 13, and the hook portion 12a at the tip of the rope is covered with the lid 1.
Then, the rope sheave is removed from the floor 2 and the lid 1a is finally closed. During this laying operation, the cylinder 6 is operated to raise the corner roller 5 to the position shown by the broken line in FIG.
A little (about 40 to 60 mm).

On the other hand, the winding operation of the artificial turf 3 laid on the floor 2 as described above can be performed, for example, in the following procedure. First, as in the laying operation, after opening the lid, installing the rope sheave, and attaching the hook portion of the rope tip to the tip fitting of the artificial turf, a plurality of air blow devices 17 are installed on both sides of the artificial turf 3. Then, by operating this device, the artificial turf 3 is floated from the floor 2 by operating this device. After the artificial turf 3 floats, the air blow device 17 is removed. At this time, the cylinder 6 is driven to raise the corner roller 5 to the position shown by the broken line in FIG. Next, the artificial turf 3 is wound around the winding shaft 7 by driving the motors 10a and 10b and rotating the receiving rollers 8a and 8b in a direction opposite to the arrow shown in the figure. Here, at the beginning of the winding of the artificial turf, only the own weight of the winding shaft 7 acts on the receiving rollers 8a and 8b, so that slippage is likely to occur between the receiving rollers 8a and 8b and the winding shaft 7. By floating the artificial turf 3 as in the embodiment, it is possible to prevent slippage, and thus to reliably wind the artificial turf.

During the winding operation of the artificial grass, the artificial grass 3
When the offset occurs, the corner roller 5 in contact with the artificial turf 3 on the offset side is raised, for example, to raise the artificial turf 3.
By tilting the artificial turf across its width, the meandering of the artificial turf can be corrected.

After the artificial turf 3 laid on the floor 2 has been completely wound, the rope is removed from the metal fittings of the artificial turf as in the case of the laying operation. The winding operation is completed by fixing the hook to the back surface of the lid, removing the rope sheave, and closing the lid.

As described above, according to the above-described embodiment, when the take-up shaft of the artificial turf is rotated by driving the receiving roller, the artificial turf is floated by the air blow device, so that the space between the take-up shaft and the receiving roller is increased. Slip is prevented, and the artificial turf is reliably wound on the winding shaft. Moreover, since the corner roller is provided at the entrance of the pit so as to be able to move up and down, it is possible to correct the meandering of the artificial turf, thereby improving the winding / laying accuracy of the artificial turf. In the above embodiment, a pit is provided at the end of the floor surface,
Although the artificial turf winding device is provided therein, the present invention can be applied to a case where no pit is provided and the artificial turf winding device is provided at the end of the floor surface.

[0018]

According to the present invention, since the artificial turf take-up device is configured to drive the receiving roller after floating the artificial turf during the storage operation, the artificial turf can be reliably taken up. Since the roller that can move up and down is brought into contact with the bent portion of the artificial turf from the laying surface of the artificial turf to the winding shaft, the effect of winding (laying) the artificial turf with high accuracy can be obtained.
