DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facility for winding and extending artificial turf laid on a large-area floor.

[0002]

2. Description of the Related Art Artificial turf is being laid on a large floor such as a sports facility. Since these facilities are used for multiple purposes, artificial turf must be laid and peeled to meet each purpose, and the artificial turf is often rolled up and spread. Conventionally, for winding this artificial turf, a self-propelled machine in which a fork of a large forklift is modified and a winding drum is mounted is used. In most cases, the expansion is performed manually.

[0003]

Since the length of the winding drum of a self-propelled machine is at most about 3 to 4 m, the width of the artificial turf wound by one operation is about 3 to 4 m.
The length of the artificial turf wound on one winding drum is at most about 30 to 40 m. For this reason, winding up the artificial turf on the entire floor of a large-area facility such as a baseball stadium requires a large number of winding drum exchanges and a large number of winding operations. Requires labor and time. In addition, since the self-propelled machine must be stored and stored in addition to the storage of the large number of winding drums on which the artificial turf is wound, a large space is required for storage.

[0004]

SUMMARY OF THE INVENTION The present invention introduces a large take-up device as compared with a self-propelled machine to reduce the time and labor required for take-up, and to take up a wound artificial turf. The storage space can be reduced by storing the storage space together with the collecting device. Further, the present invention is intended to reduce the human power by introducing mechanical power even in the work of extension which has not been taken into consideration in the past.

The first point of the present invention is that the take-up drum is enlarged and housed in a pit under the floor on the take-up side together with its drive device. The length of the winding drum of the present invention is about ten to several tens of meters, and the diameter is about one to several meters. Because of the large size, the artificial turf can be wound for a long time with a single winding operation while keeping the width of the artificial turf wide, and the area of the artificial turf that can be wound on one winding drum is remarkable. To increase. Then, the wound artificial turf is stored in the underfloor pit while being wound on the winding drum, and waits for the next expansion, so there is no need to store the winding device and the artificial turf separately, and the storage space is greatly reduced. . With the enlargement of the winding drum, deflection of the winding drum due to its own weight becomes a problem. If the take-up drum is relatively short, it can be dealt with by providing a frame material inside the take-up drum, but if the take-up drum is long, it may not be enough, so it is supported via a spring or a damper. It is preferable that the winding drum is elastically supported from below by a plurality of rollers.

A second point of the present invention is that a stretching rope is detachably attached to the extension side end of the artificial turf, and the stretching rope is wrapped around a stretching drum by a stretching device to apply mechanical force to the stretching of the artificial turf. It is a point to use. The number of stretching ropes is increased according to the width of the artificial turf, and is wound around each stretching drum by a number of stretching devices corresponding to the number of stretching ropes, and the rotational speeds of the plurality of stretching devices are coordinated. Artificial turf is being spread. At this time, the plurality of expansion devices are respectively stored in the underfloor pits on the expansion side. The spreading rope is removed from the artificial turf and stored around the spreading drum.

[0007] If it is not advisable to construct a large number of underfloor pits, the extension device is stored in the same pit as the winding device storage pit on the winding side. In this case, since the stretching device is installed on the winding side, it is necessary to reverse the direction of the stretching rope during the stretching. For this reason, a plurality of pulleys are temporarily installed on the extension side, and the direction of the extension rope is changed via the pulleys and wound around the extension drum. Also in this case, the spreading rope is removed from the artificial turf and stored while being wound on the spreading drum.

[0008] Further, the pulley is removed after the extension work is completed.

In order to facilitate the operation of the take-up / expansion equipment of the present invention, a pipe for air ejection is buried in the floor of the facility, and air is ejected at the time of take-up / expansion so that the floor and the artificial turf are connected. It is preferable to reduce the frictional resistance with the stiffener. In addition, the artificial turf has an air flow path on the bottom as an artificial turf, and uses an artificial turf that has pores for air ejection in the air flow path to blast air from the side of the artificial turf, and similarly to the floor and the artificial turf It is also desirable to reduce frictional resistance.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings.

FIG. 1 shows an example of a winding device according to the present invention, in which (a) is an elevational view, (b) is a longitudinal sectional view, and (b) is a longitudinal sectional view in a pit.

The winding drum 2 is mounted on a pedestal via a bearing, and is driven by a driving device 5 via a gear. The lower portion of the winding drum 2 is elastically supported by a receiving roller 3 fixed to the bottom surface via a spring 4. When winding the artificial turf 1, cover the underfloor pit 7
Is opened and the artificial turf 1 is pressed against the surface of the winding drum 2 to drive the winding drum 2. According to the rotation of the take-up drum 2, the artificial turf 1 is taken up by the take-up drum 2 while pushing down the receiving roller 3. When the artificial turf 1 of a predetermined length is wound, the driving is stopped and the lid 7 is closed.

FIGS. 2A and 2B are plan views showing examples of the arrangement of the winding drum 2, the expanding drum 6, the expanding rope 11, and the pulley 8 according to the present invention during the expanding operation. FIG. Is an example of an integral type, and (c) is an example of an integral / clutch switching type.

First, the separation type (a) will be described.

Before starting work, the artificial turf 1 is taken up by the winding drum 2
With the rope 1
Numeral 1 is stored in the extension pit together with the extension drum 6. When starting the work, first, the stretching rope 11 is pulled out from the stretching drum 6 and its end is fixed to the end of the artificial turf 1 on the stretching side. The plurality of spreading drums 6 are rotated by the driving device 10 while maintaining harmony, and the spreading rope 11 is wound around the spreading drum 6 to expand the artificial turf 1. During this time, the winding drum 2 is in a free rotation state, and the artificial turf 1 is unraveled from the winding drum 2 by the tension applied to the spreading rope 11. When the artificial turf 1 has been unraveled, the extension rope 11 is removed from the artificial turf 1 and the extension drum 6 is removed.
Stop the rotation of and finish the work.

Next, the integrated type (b) will be described.

Before starting work, the artificial turf 1 is taken up by the winding drum 2
With the rope 1
1 is stored in the same winding pit together with the extension drum 6. When starting the work, first, a plurality of pulleys 8 are temporarily installed on the extension side. The extension rope 11 is pulled out from the extension drum 6 and the end thereof is connected to the artificial turf 1 via the pulley 8.
To the end on the extended side of The expansion rope 6 is wound around the expansion drum 6 by rotating the expansion drum 6 by the driving device 5, and the artificial turf 1 is expanded. During this time, since the winding drum 2 is rotating in the direction in which the artificial turf 1 is sent out by the same driving device 5, the rotation of the stretching drum 6 and the rotation of the winding drum 2 are harmonized to unwind the artificial turf 1 from the winding drum 2. go. When the artificial turf 1 has been unraveled, the extension rope 11 is removed from the artificial turf 1 and wound on the extension drum 6, the driving device 5 is stopped, and finally the pulley 8 is removed to complete the operation. In the case of the integral type, take up the artificial grass 1 and take up the drum 2
Since the pulling-out force and the feeding-out force from the winding drum 2 are applied, the tension applied to the artificial turf 1 during the operation can be greatly reduced.

Next, the integral / clutch switching type (c) will be described.

The work sequence of the integral / clutch switching type is exactly the same as that of the integral type. However, the force is transmitted only to the extension drum 6 by the clutch 9 by the drive device 5 and the winding drum 2
The difference is that they are not told. During the stretching operation, the winding drum 2 is in a free rotation state, and the artificial turf 1 is released from the winding drum 2 by the tension applied to the stretching rope 11, so that the tension applied to the artificial turf 1 during the stretching operation is one. It is considerably larger than the figure.

As the floor area of the facility increases, it is necessary to install the winding / expanding equipment according to the present invention in a large amount.
Since all of the wound artificial turf is stored and stored in the underfloor pit as a unit, the space for storing and storing as a whole may be much smaller than the conventional method.

[0021]

According to the present invention, since a large winding device is used, the time and labor required for winding can be reduced. In addition, since the winding drum, the spreading drum, the driving device, and the wound artificial turf are all stored and stored integrally in the underfloor pit, the storage and storage space as a whole is much smaller than the conventional method. Furthermore, labor is reduced because mechanical power is also introduced for the work of the expansion.
