This is an artificial turf winding device in which a roller is rotationally driven by a receiving roller driving motor.

[0003]

Generally, an artificial turf formed so as to be rollable has an artificial turf planted on a rubber base so as to be easily bent and wound, and the artificial turf may be loose. The back surface of the base is formed in a flat shape without any unevenness so that there is no unevenness. On the other hand, if the artificial turf is wound inside with the above technology, the artificial turf is retracted by the frictional force between the back surface of the base and the surface of the receiving roller,
It will be wound on a winding drum. That is, since 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, the base and the receiving roller slip easily, and this phenomenon is remarkable at the start of winding. It is also conceivable to wind up 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 artificial turf itself or its base and the receiving roller. is there. Accordingly, an object of the present invention is to provide an artificial turf winding device capable of reliably winding an artificial turf.

[0004] The present invention has been made in order to achieve the above object, i.e., supported by rollers undergo main shaft fixed to one end of the artificial turf to the main shaft, the main shaft rotates driving the spindle In an artificial turf winding device for winding an artificial turf, both ends of the main shaft are respectively connected to different lifting frames.

[0005]

When the artificial turf is wound on the main shaft by rotating the main shaft, the main shaft is wound and thickened accordingly, so that the bearing of the main shaft is raised and the lifting frame is also raised. However, the lifting frame is allowed to move up and down by the guide means, but is prevented from rotating. Therefore, the spindle can be rotationally driven by the spindle drive provided on the lifting frame, and thus the spindle drive is
Although it moves up and down together with the elevating frame, its posture is always kept constant, so that a reliable winding operation can be performed.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 to 3 show an embodiment of an apparatus for winding an artificial turf according to the present invention, and this winding apparatus is provided underground at one end of a laying surface of the artificial turf. An end on the winding side of the artificial turf 1 is fixed to the main shaft 2, and a pair of front and rear receiving rollers 3 </ b> A, 3 is provided below the front and rear direction of the main shaft 2 (a horizontal direction orthogonal to the axial direction of the main shaft 2).
B are disposed, and a pair of front and rear support rollers 4A, 4B are provided below the front and rear sides of each of the receiving rollers 3A, 3B;
4C and 4D are arranged at several positions in the axial direction. Thus, one receiving roller 3A is supported by a pair of front and rear support rollers 4A and 4B disposed at several locations in the axial direction, and the other receiving roller 3B is also supported by a pair of front and rear support rollers 4C disposed at several locations in the axial direction. , 4D. Thereafter, these receiving rollers 3A,
The main shaft 2 is supported by 3B.

The supporting rollers 4A, 4B; 4C, 4D are driven rollers and are not driven to rotate, but the receiving rollers 3A, 3B and the main shaft 2 are driven to rotate. First, as shown in FIG. 3, right bearings 5R, 5R are provided at the right ends of the receiving rollers 3A, 3B.
A sprocket wheel is fixed to a portion protruding from 5R. This sprocket wheel, through the reducer,
It is rotationally driven by a receiving roller drive motor 6.
Since the loads of the receiving rollers 3A and 3B are basically supported by the supporting rollers 4A and 4B; 4C and 4D, the right bearings 5R and 5R mainly support only the thrust load. On the other hand, as shown in FIG. 1, left bearings 5L, 5L are provided at the left ends of the receiving rollers 3A, 3B. The left bearings 5L, 5L are
In view of the thermal expansion of the left and right bearings 5L, 5B
L basically does not support the load of the receiving rollers 3A and 3B nor the thrust load.

Next, the driving mechanism of the main shaft 2 will be described.
As shown in FIGS. 1 and 2, a pair of front and rear left fixed frames 7 </ b> L and 7 </ b> L is provided upright at the left end of the main shaft 2, and a pair of front and rear left guide rails 8 are provided inside the left fixed frame 7 </ b> L.
L, 8L are provided upright. Left guide rail 8L, 8L
The left elevating frame 9L is disposed inside the left and right guide rollers 10L provided at the four corners of the left elevating frame 9L.
Are arranged to travel on the left guide rails 8L, 8L, and thus the left elevating frame 9L is configured to move up and down along the left guide rails 8L, 8L. On the left elevating frame 9L, a left bearing 11L that engages with the left end of the spindle 2, a spindle drive motor 12, a speed reducer thereof, and the like are installed. In this way, the spindle 2 is rotationally driven by the spindle drive motor 12. ing. The reason why the left ascending / descending frame 9L is arranged so as to be able to ascend and descend is that the main shaft 2 becomes thicker as the artificial turf 1 is wound up.

The hanging frame 1 is placed on the left elevating frame 9L.
The suspension frame 13 is suspended from a ceiling direction by a wire rope 15 via a rope sheave 14, and a balance weight 16 is attached to the other end of the wire rope 15. Weight of the balance weight 16, the right which is installed left lifting frame 9L and the left bearing 11L installed in this, the spindle drive motor 12, the reduction gear, and a load such as a hanging frame 13, the opposite end of the drive side of the main shaft The load is adjusted to cancel the difference between the load of the lifting frame 9R and the load of the right guide roller 10R installed on the frame.

The load on the main shaft 2 itself is basically
A, 3B, and the load of the left elevating frame 9L and the main shaft drive motor 12 installed thereon is reduced by the balance weight 16, so that the left bearing 11L of the main shaft 2 is provided with the right bearing 11R. Act on
Only the load equivalent to the applied load is applied . However, left bearing 11L
Is configured to support the thrust load,
Correspondingly, a guide roller having flanges on both sides is used as the left guide roller 10L. That is, in winding the artificial turf 1, there is a possibility that the artificial turf 1 is gradually shifted rightward or leftward of the main shaft 2 and is wound. At this time, a leftward or rightward thrust load acts on the main shaft 2. I do. This thrust load is applied to the left bearing 1
1L, is transmitted to the left ascending / descending frame 9L, and further through the flanged left guide roller 10L.
L, 8L. Thus, the thrust load acting on the main shaft 2 is received by the left bearing 11L and the left guide roller 10L. Therefore, although the main shaft 2 becomes thicker as it is wound, it remains at a fixed position in the left-right direction. The deviation of the artificial turf 1 in the left and right direction during the winding process is as follows:
It is corrected by a meandering centering roller (not shown).

When the main shaft 2 is rotated counterclockwise in FIG. 2 and the artificial turf 1 is wound, as a reaction force, the entire left elevating frame 9L and the like move clockwise around the axis of the main shaft 2. Receive the moment. This moment is received by the left guide roller 10L coming into contact with the left guide rail 8L. In particular, since this moment is a clockwise moment, the lower left guide roller 10 in FIG.
L and the upper right guide roller 10L, or both.

On the other hand, as shown in FIG. 3, a pair of front and rear right fixing frames 7R, 7R are provided upright at the right end of the main shaft 2, and a pair of front and rear right guide rails 8R are provided inside the right fixing frame 7R. , 8R. A right elevating frame 9R is disposed inside the right guide rails 8R, 8R, and right guide rollers 10R provided at four corners of the right elevating frame 9R are arranged to run on the right guide rails 8R, 8R. The right ascending / descending frame 9R is thus
It is configured to move up and down along the right guide rails 8R, 8R. On the right elevating frame 9R, a right bearing 10R engaged with the right end of the main shaft 2 and the like are installed. Although the right bearing 11R of the present embodiment is configured to be able to temporarily support a thrust load, a guide roller without a flange is used as the right guide roller 10R in consideration of the temperature expansion of the main shaft 2. Therefore, no special thrust load acts on the right bearing 11R.

This embodiment is configured as described above.
When the main shaft drive motor 12 is operated to rotate the main shaft 2 in the counterclockwise direction in FIG. 2, the main shaft drive motor 12 and its speed reducer,
The left lifting frame 9L on which these are mounted receives a moment load clockwise in FIG. However, since the left guide roller 10L abuts the left guide rail 8L, the left elevating frame 9L cannot rotate clockwise, so that the main shaft 2 rotates counterclockwise to wind up the artificial turf 1. As the artificial turf 1 is wound up, the main shaft 2 becomes thicker, so that the main shaft 2 rises almost vertically, and the left bearing 1
0L and the left frame 9L also rise, and the left guide roller 10L rotates while contacting the left guide rail 8L so as to allow this. Thus, the artificial turf 1 is wound around the main shaft 2. At this time, when the receiving roller drive motor 6 is operated to rotate the receiving rollers 3A and 3B clockwise in FIG. 2, the rotation of the main shaft 2 in the counterclockwise direction becomes smooth, and the artificial turf 1 is more easily removed. Can be wound up.

As described above, in the present embodiment, the elevating frames 9R, 9L rise without any inclination in accordance with the winding of the artificial turf 1, so that the main shaft drive motor 12 mounted on the left elevating frame 9L is inclined. Nothing. Further, in this embodiment, the balance weight 1 for canceling the load of the spindle drive motor 12 and the like installed on the left elevating frame 9L is used.
5, the excessive load does not act on the left bearing 10L. In the present embodiment, the spindle drive motor 12 is provided only at the left end of the spindle 2, but a spindle drive motor may be provided at the right end. As the spindle drive motor 12, in addition to the electric motor, a hydraulic motor or the like that does not require a speed reducer can be used.

[0015]

According to the present invention, since the elevating frame simply moves up and down without tilting, the attitude of the spindle drive device mounted on the elevating frame is always kept constant, thereby securely winding the artificial turf. Can be taken.
