The present invention relates to an improvement of a rug laying apparatus that lays a rug such as an artificial turf on a floor of a gymnasium and enables removal after the heel.
[0002]
[Prior art and its problems]
In recent multi-purpose halls and gymnasiums, for example, as a separate rug on a flooring floor, for example, artificial turf can be laid to allow outdoor competitions to be performed indoors. The company intends to make it more versatile.
[0003]
Various types of rug laying devices have been proposed as an artificial turf, that is, a device for laying and removing a rug, and each has its own characteristics, but there are advantages and disadvantages. In fact, it is desirable to propose a rug laying apparatus that can further facilitate removal after dredging.
[0004]
The present invention was devised in view of such a current situation, and the object of the present invention is that it is convenient to use since it can further facilitate the laying of the rug and the removal after the dredging. It is to provide a rug laying apparatus that is optimal for expecting an improvement in performance.
[0005]
[Means for Solving the Problems]
In order to achieve the above-described object, the structure of the rug laying device according to the present invention can be drawn out to a drum that is set to be rotatable around a shaft core that is pivotally supported at both ends and extends horizontally. It is possible to pull out the rug from the drum by running a towing vehicle that holds the rug so that it can be wound and is separably connected to the tip of the rug, while the drum winds the rug using commercial power. In a rug laying apparatus that is connected to an electric drive source that operates so as to take, and is set so that pressure air from the air blow mechanism is ejected to the back side of the rug when the rug is drawn out and wound, A vertical wall is provided at a position close to the drum, a tension sensor for detecting the tension of the rug is provided at the lower end of the vertical wall, and the electric signal is detected via the controller using a signal detected by the tension sensor. While controlling the rug winding operation of the drive source, the air blow mechanism while Haizai below the drum, the spout of the gas in the air blow mechanism, toward from the ejection port in the laying direction of the rug gas Was disposed so as to face each other between the floor surface as a predetermined position for laying the rug and the back surface of the rug pulled out from the drum.
[0006]
In the basic configuration described above, more specifically, the air blow mechanism is disposed below the drum, and the pressure blowout port in the air blow mechanism is a predetermined position on which the rug is laid. Suppose that it is made to oppose between the surface and the back surface of the rug pulled out from the drum.
[0007]
At this time, the tow vehicle that is detachably connected to the leading edge of the rug and pulls the rug out of the drum is, for example, an electric drive vehicle that runs on a storage battery, and runs under the control of a boarding driver, It is assumed that the vehicle is set to travel by radio control without boarding.
[0008]
Then, it is assumed that the tow vehicle placed in a non-use state, for example, after the laying of the rug is finished, is stored in an appropriate storage space formed below the passenger seat stand, for example.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
In the following, the present invention will be described based on the illustrated embodiment. As shown in FIGS. 1 and 2, the rug laying apparatus according to the present invention has left and right ends in FIG. 1 (in FIG. 2). A drum 3 having a predetermined area pivotally supported by a pair of bearings 1 and 2 arranged on the left and right, which are vertically arranged) and configured to be rotatable about a shaft core extending in the horizontal direction. The artificial turf S, which is a rug formed into a sheet, is held so as to be drawable and rollable.
[0010]
Incidentally, the artificial turf S here is set to a standard length having a length and a width that allow two courts C of the gateball game to be taken, for example, as shown by a one-dot chain line in FIG.
[0011]
The place where the artificial turf S is spread is, for example, a flooring floor F (see FIG. 1) as an indoor floor in a gymnasium A or the like.
[0012]
On the other hand, this rug laying apparatus is configured such that one end of the drum 3 is connected to an electric drive source 4 disposed adjacent to one bearing 1 and an air blow mechanism 5 is disposed below the drum 3. As shown in the partial diagram of the solid line in FIG. 1, the artificial turf S is set to be pulled out to a predetermined position by the traveling of a plurality of tow vehicles P that are detachably connected to the tip of the artificial turf S. .
[0013]
Although not shown in detail, the plurality of tow vehicles P are, for example, electrically driven vehicles that run on a storage battery, and run by the pilot of the rider, or the pilot does not get on. Then, suppose that it is set to any one of traveling by radio control.
[0014]
Further, when the plurality of tow vehicles P are not in use, for example, after the artificial grass S has been laid, as shown in FIG. 1, for example, so-called walls of a gymnasium A that partitions the flooring floor F are used. Although stored in the dedicated storage space A1 such as formed inside, instead of being stored in the storage space A1, it may be stored in a storage space formed below the audience seat stand, for example.
[0015]
In the storage space A1, it is preferable to take into consideration that the state in which the tow vehicle P is stored by a door D such as a shutter can be concealed.
[0016]
By the way, the drum 3 is formed so as to be able to completely wind up the artificial turf S having a predetermined width, length and thickness, that is, to have a predetermined size and a predetermined mechanical strength. Of course, as shown in the figure, the flange 31 functions as a stopper for preventing the protrusion when the artificial grass S is wound around the vicinity of both ends.
[0017]
The drum 3 is rotated at one end by being connected to an electric drive source 4 disposed adjacent to one bearing 1, that is, by driving the electric drive source 4. It is set to perform winding.
[0018]
Therefore, the drum 3 has a large-diameter pulley 32 at one end. As shown in FIG. 3, the drum 3 is electrically connected via an infinite band B such as a chain wound around the large-diameter pulley 32. It is assumed that it is connected to the drive source 4.
[0019]
Incidentally, the same applies to one end of the drum 3, but the other end of the drum 3 is pivotally supported by the bearing 2 in a state in which so-called slippage is prevented. In terms of arrangement, it is assumed that the upper end is installed on the bases 11 and 12 set at a height substantially matching the upper end of the flooring floor F.
[0020]
On the other hand, the electric drive source 4 has a motor driven by a commercial power source, a speed reducer for controlling the motor speed to be reduced, and a small-diameter pulley 32 held by the speed reducer. Thus, the pulley 32 is wound with the infinite belt.
[0021]
At this time, the electrical drive source 4 is in the present invention, and is set to execute the winding of the artificial turf S while allowing the artificial turf S to be pulled out by the rotation of the drum 3. Therefore, when this is activated, the drum 3 functions only to wind up the artificial grass S.
[0022]
Incidentally, when the artificial turf S is pulled out from the drum 3 by using the towing vehicle P, the electric drive source 4 is maintained in a non-operating state by turning off the power, or maintained in a so-called neutral state. Will be maintained in an inoperative state.
[0023]
The air blow mechanism 5 forms an air layer between the flooring floor F and the artificial turf S by its operation, and laying the artificial turf S by the tow vehicle P and the electric drive source 4 on the principle of a so-called air slider. Is provided for facilitating the rotation of the drum 3 by the operation of, ie, the winding of the artificial turf S.
[0024]
Therefore, in the illustrated embodiment, as shown in FIGS. 3 and 4, the air blow mechanism 5 includes a main body 51 that takes in outside air and discharges it as pressurized air, and a main body 51 connected to the main body 51. The pipe 52 through which the pressure air from the pipe 51 passes is provided, and the jet outlet 52a at the tip of the pipe 52 is set to face the flooring floor F and the artificial grass S.
[0025]
The air blow mechanism 5 is set so that the main body 51 operates by using a commercial power source in the same manner as the electric drive source 4 described above.
[0027]
Therefore, in the rug laying apparatus according to the present invention, an air layer can be formed between the back surface of the artificial turf S and the top surface of the flooring floor F by the operation of the air blow mechanism 5. As a result, it is possible to reduce the operating force required when the artificial turf S is pulled out and wound up, and in other words, it is not necessary to set the entire apparatus to a large scale.
[0028]
As described above, in the present invention, the artificial turf S that is a rug can be laid by using the towing vehicle P, and the artificial turf S can be removed by using the drum 3 that rotates by the operation of the electric drive source 4. However, the following considerations are also made.
[0029]
That is, first, in order to prevent the artificial turf S from drooping greatly from the drum 3 when the artificial turf S is pulled out by the traveling of the towing vehicle P or wound by the rotation of the drum 3, FIG. 3 and FIG. As described above, the support roller 6 is provided, and the support roller 6 is arranged along the drum 3 in the vicinity below the drum 3.
[0030]
Therefore, the artificial turf S does not hang down more than necessary due to the arrangement of the support rollers 6, so-called resistance is reduced, and it is possible not to increase the operating force required when the artificial turf S is drawn out and wound up. become.
[0031]
Next, when the artificial turf S is pulled out by running the towing vehicle P or wound by the rotation of the drum 3, care should be taken not to break the artificial turf S so as not to apply excessive tension to the artificial turf S. ing.
[0032]
Namely, in the the rug laying device, during its installation, and the drum 3 is disposed in such machine room (not Shimese marks) formed on the so-called inner walls defining a gymnasium A, At this time, the vertical wall 7 is provided and partitioned between the machine room and the so-called floor portion of the gymnasium A.
[0033]
Therefore, a tension sensor 8 is provided at the lower end of the hanging wall 7, the tension acting on the artificial grass S is detected by the tension sensor 8, and the detection result is input to a controller (not shown) and input to the controller in advance. A signal obtained as a result of processing based on the set value is output to the outside.
[0034]
As a result, when this signal is set to be input to the electric drive source 4, the operation of the electric drive source 4 is controlled to wind the artificial turf S by the rotation of the drum 3. Thus, the tension acting on the artificial turf S can be reduced, and for example, the artificial turf S can be prevented from being damaged by excessive tension.
When the signal from the controller is transmitted to the above-described towing vehicle P or a pilot operating the towing vehicle P by an appropriate means, the traveling speed of the towing vehicle P is controlled by controlling the traveling speed of the towing vehicle P. When the artificial turf S is pulled out by running, the tension acting on the artificial turf S can be reduced.
[0036]
In the above description, the rug laying apparatus according to the present invention has been described as laying and removing the artificial turf S as a rug. However, from the intent of the present invention, the rug is not illustrated, but for example, It may be used, or may be a curing sheet.
[0037]
And when the rug is a curing sheet, it becomes possible to perform the flooring work prior to other interior work during the construction work such as the gymnasium A where the rug laying apparatus is installed, When the predetermined work is completed and curing of the flooring floor F is not required, it is advantageous in that a desired rug, for example, artificial turf S can be wound around the drum 3 instead of the curing sheet.
[0038]
Moreover, although the case where the rug laying apparatus according to the present invention lays a rug in a so-called partitioned space such as a gymnasium A is taken as an example, according to the intention of the present invention, the place where the rug is laid is not partitioned. Of course, it may be an open space.
[0039]
【The invention's effect】
As described above, in the rug laying apparatus according to the present invention, the traction vehicle is used when the rug is laid, and the electric drive source that operates with the commercial power source is used when the rug is removed. Since the load of the rug is apparently reduced using the air slider principle by the air blow mechanism, the work of laying and removing the rug becomes easy, and the enlargement of the entire apparatus can be avoided.
[0040]
As a result, according to the present invention, it is convenient to use because it can further facilitate the laying of the rug and the removal after the dredging, and it is optimal for expecting an improvement in its versatility.
Furthermore, a tension sensor is provided at the lower end of the hanging wall, the tension acting on the rug is detected by this tension sensor, the detection result is input to the controller, and based on the set value input in advance to the controller. Since the processed signal is output to the outside and this signal is input to the electric drive source to control the winding operation of the electric drive source, the rug is wound when the rug is wound by rotating the drum. For example, the rug can be prevented from being damaged by an excessive tension.
When the signal from the controller is transmitted to the tow vehicle or the operator who operates the tow vehicle by an appropriate means, the rug pulling out by the traveling of the tow vehicle is controlled by controlling the traveling speed of the tow vehicle. In this case, the tension acting on the rug can be reduced.
