Description

Pyrotechnic MEAL POWDER SUPPLYING APPARATUS FOR MANUFACTURING FIREWORKS

The present invention relates to a device for precisely weighing the weight of a pyrotechnic meal powder used in a flower fire and supplying it into a branch pipe, using a load cell to supply the gunpowder to be supplied into a branch pipe for producing a flower flame generating a flame in a fountain form. The present invention relates to a gunpowder supply device for producing a flower fire.

A flower fire (fireworks) is a chemical product that combines various effects such as light, sound, and smoke that can be displayed by explosives.These flower fires include toy plugs, bruises that are used for shooting at altitudes over 100m, and less than 100m. They can be classified as device fires, which are fired at heights or constructed on sea or ground structures to burn letters, flora and fauna, waterfalls and other shapes.

Since the gunpowder used for the flower fire requires precise combustibility, and the height and the combustion time of the flame are determined according to the amount of gunpowder, it is very important to accurately measure and supply the amount of gunpowder in the process of manufacturing the flower fire.

In the process of manufacturing a flower flame that generates a flame in the form of a fountain, gunpowder is put into the inside of a pipe-shaped branch pipe, which is open at both sides, and then compressed to form a first soil layer. After supplying a certain amount of compressed to form a gunpowder layer, and then put the soil again to compress to form a second soil layer.

Then, puncture the center of the first soil layer, and inserting the medicated paper with the gunpowder powder in order to assist the ignition inside the perforated soil layer, and then insert the ignition jade ignition means into the perforated soil layer, the top of the branch pipe Finishing with a paper blowout sticker and taping the blowout sticker to complete the production of a flower fire generating a fountain-shaped flame.

In the above process, the amount of gunpowder injected into the branch pipe to form the gunpowder layer is usually divided into 1/6, and the process of compressing after supplying is repeatedly performed.

Because if you load and compress a lot of gunpowder inside the branch pipe, the pressure of gunpowder is different according to the height of the gunpowder. When you ignite the gunpowder layer after the compression process is completed, the flame penetrates into the weaker compressed gunpowder layer. Since the following problem occurs, in order to prevent such explosions by inserting a certain amount of gunpowder and repeating the compression process to ensure that the entire gunpowder layer is formed at the same pressure.

The process of measuring and supplying gunpowder to a branch pipe to produce a conventional flower-fired fountain is as follows.

When the amount of gunpowder to be supplied to the branch is determined, the amount of gunpowder to be supplied to the branch is usually divided into one sixth, and the operator weighs it in a precision scale.Then, the powdered gun powder is supplied to the branch by using a funnel, etc. The process of measuring and supplying was repeated as many times as the number of gunpowder divided.

However, in the case of supplying the branch pipe by measuring the gunpowder using a precision balance as in the prior art, there were the following problems.

First, since the error generated in the process of measuring the gunpowder becomes larger in the metering supply process, the flame height or the burning time of the final flower product is not uniform, and such a flower light is installed indoors for performances. There was a risk of damage to property and life.

Second, in the process of supplying the gunpowder to the branch pipe by using the funnel and the like, not only an error in the amount of gunpowder is generated, but also a problem of deteriorating the working condition due to the scattering of gunpowder dust.

Third, when relying on manual work as in the past, there was a problem in that the cost of the final flower product was increased due to excessive time and manpower.

The present invention has been invented to solve the problems in the prior art as described above, the gunpowder storage unit for dropping a predetermined amount of gunpowder among the first gunpowder stored in the gunpowder storage hopper, and dropping the gunpowder supply pipe from the gunpowder storage hopper Control the height by raising and lowering the gunpowder metering unit for weighing the amount of gunpowder with a load cell, and storing the secondary gun, an opening and closing block driving unit for opening and closing the blocking block blocking the flow path under the gunpowder supply pipe, and elevating the holders for fixing the plurality of branch pipes. And a control part 500 for setting the amount of gunpowder to be supplied to the branch pipe and receiving an electrical signal for the amount of gunpowder stored in the gunpowder supply pipe from the load cell to control the operation of the gunpowder control cylinder.

Hereinafter, with reference to the accompanying drawings will be described in detail with respect to the present invention.

1 and 2, the gunpowder storage unit 100 for storing the gunpowder primarily to drop a predetermined amount of gunpowder, and the amount of gunpowder dropped while storing the dropped gunpowder secondary Gun pipe to adjust the height by raising and lowering the gunpowder metering unit 200 for weighing and supplying to the paper pipe, the opening and closing block drive unit 300 for dropping the second stored weighed gunpowder into the paper pipe, and the paper holder holder fixed a plurality of paper pipes. The holder fixing part 400 and the control unit 500 to set the amount of gunpowder to be supplied to the branch pipe and to adjust the amount of the gunpowder stored primarily.

First, as illustrated in FIG. 3, a gasket 121 is inserted in the middle of the outer circumferential surface of the plurality of gunpowder storage hoppers 110 constituting the gunpowder storage unit 100 to be firmly fixed to the hopper fixing plate 120.

The material of the gunpowder storage hopper 110 can be visually confirmed the storage amount and flow state of the gunpowder using a transparent acrylic.

However, in the initial stage of the gunpowder supply process, the gunpowder is frequently not discharged smoothly due to the electrostatic force generated in the gunpowder particles stored in the gunpowder storage hopper 110, and the like.

Therefore, by operating the vibrator 140 installed on the hopper fixing plate 120 in the initial stage of the gunpowder supply process, the vibration rubber block 141 attached to both sides of the hopper fixing plate 120 is in contact with and disconnected from the frame. The gunpowder is smoothly discharged by vibrating the gunpowder inside the storage hopper 110 repeatedly.

The lower portion of the gunpowder storage hopper 110, as shown in Figure 4, is formed with a throttle portion 113 is reduced in cross-sectional area toward the lower side, and adjusts the amount of the gunpowder to the lower side of the throttle portion 113 A rectangular parallelepiped knife 132 fixed to the bracket 133 connected to the end of the cylinder rod 131 of the gunpowder adjustment cylinder 130 is installed through the lower side of the throttle portion 112.

At this time, the knife fixing block 114 is unevenly coupled to the bottom of the gunpowder storage hopper 110 of the upper throttle portion 113 is coupled to the outer periphery of the throttle portion 113, through the groove formed on the side of the knife fixing block 114 The knife 132 is inserted to reciprocate.

As shown in FIG. 5, the gunpowder discharge hole 134 is formed in the middle of the knife 132 so that the flow path of the throttle part 112 and the gunpowder discharge hole 134 are in the initial state in which the cylinder rod 131 is backward. ) And the gunpowder does not fall to the lower part. On the contrary, when the cylinder rod 131 is advanced, the flow path of the throttle part 112 and the gunpowder discharge hole 134 coincide, and the gunpowder falls to the bottom. It depends on the time that the cylinder rod 131 is advanced.

At this time, the angle of the inclined surface of the throttle portion 113 and the center line of the gunpowder storage hopper 110 is preferably set to 5 ° to 15 °. If the angle is less than 5 °, the throttle portion 113 is too long and the knife fixing block 114 is too long, so design efficiency is inferior, and if the angle exceeds 15 °, the exit is blocked. .

Next, as illustrated in FIG. 6, the gunpowder metering unit 200 is provided with a gunpowder supply pipe 210 having a flow path 211 formed at the center under the gunpowder storage hopper 110 and falling from the throttle part 113. Gunpowder is stored secondary.

At this time, the gunpowder supply pipe 210 is made of a transparent acrylic material to visually confirm the storage state of the gunpowder.

A load cell 230 protruding in the middle of the outer circumferential surface of the gunpowder supply pipe 210 is provided with a load cell 230 for detecting the weight of the gunpowder stored second in the gunpowder supply pipe 210, thereby detecting the weight of the detected gunpowder by an electrical signal. The conversion is transmitted to the control unit 500.

The control unit 500 sets the amount of gunpowder to be supplied to the branch pipe in advance, and then the gunpowder begins to fall through the gunpowder discharge hole 134 by advancing the cylinder rod 131 of the gunpowder control cylinder 130 and the load cell. When the electrical signal is received from the 230, the gunpowder falling from the throttle part 113 is blocked by reversing the cylinder rod 131 of the gunpowder control cylinder 130.

However, since a small amount of powder is dropped into the gunpowder discharge hole 134 formed in the knife 132 while the cylinder rod 131 is received backward by receiving the electrical signal from the load cell 230, a correct amount of gunpowder is corrected to be measured. This is necessary.

That is, as described in Equation 1 below, the gunpowder discharge hole 134 is closed by an electrical signal transmitted from the load cell 230 to the controller 500 at the gunpowder W1 to be supplied to the branch pipe 431. Before the gunpowder is supplied to the branch pipe 431, the corrected gunpowder amount W3 minus the gunpowder amount W2 falling for a time is checked in advance to set the controller 500.

W3 = W1-W2

(W3 is the amount of gunpowder to be corrected, W1 is the amount of gunpowder to be supplied to the branch pipe 431, and W2 is the amount of gunpowder dropped during the closing time of the gunpowder discharge hole 134.)

Next, when the gunpowder begins to fall by advancing the cylinder rod 131 of the gunpowder adjusting cylinder 130 and the corrected gunpowder amount W3 is detected in the load cell 230, the electric signal is transmitted to the controller 500. By retracting the cylinder rod 131 in the control unit 500 to close the gunpowder discharge hole 134, it is possible to precisely measure the amount of gunpowder.

And, the drive cylinder 320 for reciprocating the cylinder rod 322 connected to one side of the drive frame 310 to the left and right is installed on the drive cylinder plate 321.

In addition, a guide rod 333 connected to the other side of the drive frame is installed on the drive cylinder plate 321 to guide the reciprocating motion of the drive frame 310.

Both ends of the driving pins 223 of the opening / closing block 220 are inserted into the driving grooves 311 formed on the front and rear surfaces of the driving frame 220 to drive the driving pins 223 pivoting around the hinge pins 222. Provide space.

As shown in FIG. 7A, the driving frame 310 in the state in which the opening / closing block 220 is closed is inserted into the driving pin 223 without being in contact with the driving groove 311 as shown in FIG. 7B. It does not affect the load cell 230 which is also sensitive to vibration.

On the contrary, as shown in FIG. 8A, the driving frame 310 in the open / closed block 220 is opened, and as shown in FIG. 8B, the driving pin 223 is slid to the driving groove 311 to be raised and weighed. Gunpowder is supplied to the branch pipe 431 through the nozzle 214.

Next, as shown in FIG. 9, the branch holder fixing part 400 is connected to the base frame 410 which is not connected to the gunpowder storage part 100, the gunpowder metering part 200, and the opening / closing block driving part 300. The guide part 421 is provided on the base frame 410 so that the branch pipe holder 410 is slidingly inserted, and the stopper 422 protrudes behind the guide part 421 to fix the branch pipe holder 410. Branch holder plate 410 is installed.

At this time, the branch pipe holder plate 410 is moved up and down by the rotation of the lifting handle 424 of the lower screw 423 connected to the center of the bottom is adjusted the height of the branch pipe holder 410.

In addition, the guide rod 425 is vertically connected to both sides of the bottom surface of the branch holder plate 410 and inserted into the bush 411 installed on both sides of the base frame 410, thereby lowering and lowering the branch holder plate 410 by the screw 423. Guided).

Finally, the control unit 500 receives the electrical signal for the gunpowder mass detected from the load cell 230 at the same time as setting the amount of gunpowder to be injected into the branch pipe 431 in advance stored in the gunpowder storage hopper 110 The gunpowder control cylinder 130 to drop the gunpowder is controlled.

In addition, the control unit 500 may separately control the drive cylinder 320 that is metered in the gunpowder supply pipe 210 to supply the second stored gunpowder to the branch pipe 431, a separate toggle switch (not shown) H) can be installed to control the forward operation of the gunpowder control cylinder 130 and the reciprocation of the drive cylinder 320.

Hereinafter will be described in detail the operation of the present invention configured as described above.

Then, setting the required amount of gunpowder to the control unit 500 and advances the cylinder rod 131 of the gunpowder control cylinder 130, the gunpowder begins to fall into the gunpowder supply pipe 210 through the gunpowder discharge hole 134. .

When the amount of correction gunpowder W3 described in Equation 1 is detected in the load cell 230 attached to the gunpowder supply pipe 210, the controller 500 instructs the cylinder rod 131 to reverse the gunpowder discharge hole 134. By closing, the supply of gunpowder is stopped.

Next, when the cylinder rod 322 of the driving cylinder 320 is advanced, the driving pin 223 inserted without being interfered with the driving groove 311 is pushed and the opening / closing block 220 is shown in FIG. 8A. The gunpowder precisely metered while rotating about the hinge pin 222 is introduced into the branch pipe 431 from the nozzle 214 of the gunpowder supply pipe 210.

After the injection of the gunpowder metered into the branch pipe 431 is completed as described above, when the cylinder rod 322 of the driving cylinder 320 is reversed, as illustrated in FIG. 7A, the opening / closing block 220 is hinge pin 222. The reverse rotation of the driving pin 223 is returned to the initial state uninterrupted in the lower driving groove (311).

After injecting gunpowder into the branch pipe 431 through this process, the branch pipe holder 430 is separated from the branch pipe holder plate 420 and subjected to the compression process of the gunpowder, and then the branch pipe holder 430 is the branch pipe holder plate 420. ) And then repeat the process of measuring the gunpowder and supplying it to the branch pipe (431) as described above.
