Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

1, the launch device 1 according to the present embodiment includes a launch pipe 100 serving as a barrel in which a projectile is accommodated and guides the launch of the projectile, And a compressed gas supplier 200 for providing a compressed gas for launching the projectile in the launch tube 100.

The compressed gas supplier 200 is provided with a guide passage 210 for guiding compressed gas in the direction of the tube and a valve unit 300 for selectively opening and closing the guide passage 200 is provided in the guide passage 200.

It is preferable that the launch tube 100 and the compressed gas supplier 200 are detachably connected to each other to easily supply the projectile into the launch tube 100.

A speed sensor unit 300 is provided at a position adjacent to the exit of the launch tube 100. The speed sensor unit 300 measures the speed of the projectile emitted from the launch tube 100 and discharged.

The speed sensor unit 300 includes a housing 310 installed at an outlet of the launch tube 100, a plurality of sensors 320 provided at the housing 310 to sense a passage state of the projectile, 320, and calculates a speed of the projectile in consideration of the passage time of the projectile sensed by each sensor 320 and the distance between the sensors.

The memory unit 340 is connected to the operation unit 330. The memory unit 340 stores the matched data between the pressure of the gas supplied at the time of launching the projectile and the launch rate of the projectile in association with the control unit 650 Function.

When the user inputs a desired speed of the desired projectile, the controller 650 invokes the pressure value of the gas corresponding to the speed, and the compressed gas supplier 200 compresses the compressed gas according to the pressure value .

A rotary motor 400 for rotating the tube 100 is provided at a lower portion (or an upper portion) of the tube 100.

The rotation motor 400 is preferably provided as a servo motor for precise control of the rotation speed, but is not limited thereto.

When launching the projectile, it is necessary to launch the robot in the state of providing the rotary motion to simulate the launch situation of the actual projectile. This is the same reason as forming the rotation wire in the general gun barrel.

The rotary motor 400 includes a first rotary member 410 and a second rotary member 420 on the outer circumferential surface of the tube 100.

The first rotary member 410 and the second rotary member 420 are connected to each other by a predetermined power transmission unit (not shown).

The first and second rotary members 410 and 420 may be gears or pulleys, and the power transmission unit may be a belt.

Furthermore, it is preferable that the pulleys are subjected to trimming treatment so as to form teeth on the outer circumferential surface thereof, and the belt is preferably composed of a timing belt.

This is to ensure that the rotational force is transmitted accurately.

The tube 100 may be rotated by a power transmission unit (not shown) such as a rotary motor 400 and the first and second rotary members 410 and a belt. However, in addition to such a driving system, A direct drive type in which the tube 100 is directly connected to the rotary motor 400 is also possible.

In this case, it is conceivable that gears are provided around the tube 100 and the rotary shaft of the rotary motor 400 so that the gears are engaged with each other.

Alternatively, friction wheels may be disposed on the rotary shaft of the rotary motor 400 and on the outer circumferential surface of the tube 100, respectively, and the friction wheels may be driven by frictional force to rotate the tube 100.

The launch tube 100 must be rotatably supported. To this end, the tube 100 is supported by a rotary support 500.

The rotary support part 500 includes a plurality of support blocks 510 arranged in a mutually perpendicular direction and spaced apart from each other and a support pipe 520 provided between the support block 510 and surrounding the outer circumferential surface of the launch tube 100, And a support bearing 530 provided inside the support block 520.

Therefore, even when the tube 100 rotates by the rotation motor 400, its position can be maintained unchanged.

The rotation support part 500 is installed in a plate-shaped moving member 550 provided at a lower part thereof.

The moving member 550 is provided to move in the forward and backward directions, and the moving member 500 can be moved in association with a hydraulic device (not shown).

The moving member 550 is supported over the guide member 551.

The guide member 551 is provided in the form of a bar extending in the front-rear direction.

The guide member 551 serves to guide the moving member 550 in the forward and backward directions, and may be formed in a rail shape instead of a bar shape.

The pressurized gas supplying unit 200 and the casting tube 100, the moving member 550 and the rotary support unit 500 are fixed to a supporting plate 580 disposed below the supporting plate 580, Lt; / RTI >

The support plate 580 may be supported by the support frame 600.

The control unit 650 may control the compression gas supply unit 200, the valve unit 250, the memory unit 340, A rotation motor 400, and a later-described launch angle control unit 700 so as to control their operation.

That is, the controller 650 may adjust the pressure of the compressed gas supplied to the compressed gas supplier 200 to adjust the firing rate of the projectile.

However, the control of the pressure of the compressed gas provided to the compressed gas supplier 200 can be automatically controlled by the controller 650, and can be manually adjusted by the user.

That is, when the pressure is automatically controlled by the control unit 650, if the user inputs a desired speed of the projectile, the pressure can be automatically adjusted to match the pressure of the gas that can realize the input speed.

Therefore, when the launching speed of the projectile is inputted at a relatively low speed, the compressed gas supplier 200 is filled with the relatively low-pressure compressed gas and when the launching speed of the projectile is inputted at a relatively high speed, The compressed gas is filled.

In the interior of the support frame 600, a fire angle adjusting unit 700 is connected to the support plate 580.

An upper end of the launch angle control unit 700 is rotatably coupled to a lower portion of the support plate 580 and a lower end thereof is rotatably coupled to a bottom portion 601 of the support frame 600.

When the support plate 580 is pushed upward due to the increase in the length of the launch angle control unit 700, the angle of emission can be increased. In the case where the support plate 580 is pulled down due to the reduced length, The firing angle can be reduced.

Here, the launch angle is defined as the angle between the horizontal plane and the launch tube with respect to the horizontal plane.

The launch angle control unit 700 may be implemented as a power cylinder. That is, the launch angle control unit 700 includes a drive motor 701, a power transmission unit 702 in the form of a gear box connected to the drive motor 701, a rod unit 702 rotated by the power transmission unit 702, And a screw part 704 which is screwed to the rod part 703 and is extended or contracted in a direction of rotation of the rod part 703.

The screw portion 704 is preferably housed in the housing 705 and a bellows portion 706 made of a rubber material capable of expanding and contracting in length is disposed on the front end (upper end portion) of the housing 705 desirable.

Accordingly, the threaded portion 704 can be moved upward or downward according to the rotational force of the drive motor 701 and rotation direction switching.

When the user inputs a desired launch angle, the drive motor 701 is operated by the control unit 650 to increase or decrease the launch angle.

Thus, the launch angle can be controlled.

A guide groove 611 in the form of an arc is provided on both side walls 610 of the support frame 600.

A bracket 582 is provided at the rear of the support plate 580 and an insertion member 585 such as a screw or a projection is provided in the bracket 582. The insertion member 585 is inserted into the guide groove 611 .

The insertion member 585 is moved upward and downward along the guide groove 611 when the launch angle of the insertion angle adjusting unit 700 is adjusted in a state where the insertion member 585 is inserted into the guide groove 611, Can move.

The insertion member 585 and the guide groove 611 serve to form a curved line corresponding to the shape of the guide groove 611 when the launch angle of the launch tube 100 is adjusted.

A first bracket 581 and a second bracket 582 are provided on the lower portion of the support plate 580. The first bracket 581 and the second bracket 582 are rotatably coupled to each other.

A third bracket 583 is disposed between the first bracket 581 and the second bracket 582. The third bracket 583 is disposed between the first and second brackets 581 and 582, And is pivotally coupled to the intermediate portion.

The portion where the third bracket 583 is installed is a rotation center of the tube 100, and a rotary shaft 586 is preferably provided.

That is, when the launch angle of the launch tube 100 is increased while rotating around the rotation axis 586, the outlet of the launch tube 100 goes up and the insert member 585 goes down.

When the launch angle is reduced, the outlet of the tube 100 is lowered and the insertion member 585 is moved upward.

The support frame 600 may include a fourth bracket 604 coupled to the bottom portion 601 such that the lower end of the launch angle control portion 700 is pivotally coupled.

An input unit 350 functioning as an interface for inputting a firing speed, a firing angle, and a rotational speed of the tube is provided. The user selects a desired rotational speed, a firing speed, and a firing angle through the input unit 350 .

FIG. 2 shows a detailed configuration of the high-pressure gas supply unit 200 and the valve unit 250.

The high pressure gas supplier 200 includes a compressed gas tank 201 in which a high pressure gas is accommodated and a guide passage 210 provided in front of the compressed gas tank 201.

The high-pressure gas to be charged into the compressed gas tank 201 is preferably high-pressure air or high-pressure nitrogen gas, but is not limited thereto.

The compressed gas tank 201 is connected to an external gas supply unit (not shown). The supply amount of the compressed gas tank 201 is controlled by a supply valve 202.

Meanwhile, the compressed gas tank 201 is connected to a pressure measuring unit 203 for measuring the internal pressure so that the pressure inside the compressed gas tank 201 can be displayed.

The supply valve 202 and the pressure measuring unit 203 may be connected to the controller 650.

Accordingly, when the user inputs a desired emission rate of the projectile or the pressure of the desired compressed gas, the controller 650 controls the supply valve 202 to be filled with the desired pressure inside the compressed gas tank 201 .

In this embodiment, the pressure can be adjusted within a range of 0 to 100 bar, but not limited thereto, and a larger pressure control is also possible.

The guide passage 210 includes a plurality of branch passages 211 separated from each other and a merging flow passage 212 through which the gases passing through the branch passages 211 join.

The second rotating member 420 provided on the outer circumferential surface of the launch tube 100 and the first rotating member 410 installed on the rotating motor 400 are vertically aligned.

And is thereby connected by the power transmission portion in the form of a belt.

The moving member 550 is provided at a lower portion of the launch tube 100 and the lower portion of the supporting block 510 and the guide member 551 is disposed at both sides of the lower surface of the moving member 550.

4 is a configuration diagram of the launch angle adjusting unit 700. As shown in FIG.

The launch angle control unit 700 includes a power transmission unit 702 including a rotation motor 701 and gear units connected to the rotation motor 701, a rod unit 703 connected to the power transmission units, And a threaded portion 704 connected to the rod portion 703.

The power transmitting portion 702 is received in a first receiving housing 711 and the rod portion 703 and the threaded portion 704 are received in a second receiving housing 712. The bellows portion 706 is provided at one end of the second housing housing 712.

When the rod portion 703 rotates due to the operation of the rotation motor 701 and the power transmission of the power transmission portion 702 because the screw portion 704 is screwed to the rod portion 703 , The protrusion length can be increased or decreased while the threaded portion 704 is rotated forward or reverse.

Thus, the launch angle can be adjusted by pushing up or down the support plate (see FIG. 1, 580).

5, the support plate 580 is pushed upward by the operation of the launch angle control unit 700 to increase the launch angle of the launch tube 100. [

At this time, the insertion member 585 is disposed to move downward along the guide groove 611.

FIGS. 6 and 7 illustrate the difference in the state of coupling or separation between the launch tube and the compressed gas supplier 200.

However, in FIGS. 6 and 7, the illustration of the emission angle adjusting unit is omitted.

6, in order to insert a projectile into the tube 100 in a state where the tube 100 and the compressed gas supplier 200 are coupled, the tube 100 is moved forward as shown in FIG. 7, Thereby separating the study 200 and the launch tube 100 from each other.

The moving member 550 moves forward in order to separate the compressed gas supplier 200 and the launch tube 100. At this time, the moving member 550 moves forward along the guide member 551 Can be moved.

When the compressed gas supplier 200 and the launch tube 100 are separated from each other, the worker or the work robot inserts the projectile into the rear end of the launch tube 100, moves the moving member 550 rearward, Connects the tube 100 and the compressed gas supplier 200, and fastens them.

Hereinafter, the operation of the present invention will be described with reference to the accompanying drawings.

8, when the valve moving body 251 is moved backward in a state where the launching body 100 is coupled to the compressed gas supplying part 200 and the projecting body B is inserted into the rear end of the launching tube 100, The compressed gas stored in the compressed gas tank 201 moves to the launching tube 100 along the branch flow path 211 and the merging flow path 212 to push and launch the projectile B.

As described above, the pressure inside the compressed gas tank 201 is adjustable, and thereby the emission speed of the projectile B can be controlled.

Adjustment of the firing rate may be implemented by providing a pressure that matches the speed entered by the user, and such speed-pressure matching data may be retrieved from the memory unit 340.

In the case of the branched flow passage 211, although the cross sectional area of each of the branched flow passages 211 is small, a large amount of compressed gas can move within a very short time when the compressed air moves along the branched flow passage 211, The launching power can be doubled.

In addition, the flow path is not a long pipe shape but a short shape, and a gas having a tapered diffuser is gathered toward the launch tube 100 at the confluent flow path 212, so that a large force can be applied to the projectile at a time.

Before the projectile B is fired, the tube 100 is rotated by the rotary motor 400. At this time, the number of revolutions of the tube 100 is about 2000 rpm , But may exceed or fall below this.

The rotational speed of the launch tube 100 can be selected by the user as required.

The sensor 320 provided in the speed sensor unit 300 irradiates light and when the projectile B is fired and passes the area of the light irradiated by each sensor 320, And recognizes the passing time of the projectile.

Since the time recognized by each sensor 320 is different from each other, a time interval can not be obtained. The speed of the projectile B can be measured by knowing the time interval and the distance value of the sensors.

In order to adjust the launch angle of the launch tube 100, the length of the launch angle adjuster 700 may be increased or decreased by controlling the launch angle adjuster 700, As shown in FIG.

Those skilled in the art will appreciate that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.

Therefore, it is to be understood that the above-described embodiments are illustrative in all aspects and not restrictive.

The scope of the present invention is defined by the appended claims rather than the detailed description and all changes or modifications derived from the meaning and scope of the claims and their equivalents are to be construed as being included within the scope of the present invention do.
