Description

Technical Field

[0001] This application relates to the field of fireworks production equipment technology, and in particular to an inner tube filling device for combination fireworks and fireworks production equipment. Background Technology

[0002] Many fireworks products have an inner tube, which is installed in the launch hole of the fireworks launcher. The fireworks inner tube, also known as the fireworks effect tube, contains bright beads, gunpowder, fillers, and igniters. Both the bright beads and gunpowder are flammable and explosive. When ignited, it produces various effects on the fireworks, such as colorful displays and various sounds.

[0003] In the production of combination fireworks, an inner cylinder filling device inserts the inner cylinder into the launch hole of the fireworks launcher. Chinese Patent 202521500809.0 discloses a filling and discharging assembly for fireworks inner cylinders and a combination fireworks production device. The inner cylinder in the hopper first falls into a groove on a circumferential transmission component. As the circumferential transmission component moves, the groove containing the inner cylinder moves to the position of the pushing mechanism, which then pushes the inner cylinder out of the groove. Such equipment generally requires a transfer template. The output inner cylinder is first loaded into the transfer template and then transferred from the transfer template to the fireworks launcher. This type of equipment is structurally complex, costly, and lacks flexibility in use. Utility Model Content

The first drive unit 23 is a servo motor that drives one of the sprockets to rotate.

[0045] A ring of sliding groove structures 24 is fixed around the circumferential transmission component 21. As the circumferential transmission component 21 moves, each sliding groove structure 24 passes through the discharge port 12 in sequence, and the inner cylinder in the material trough 11 can fall onto each sliding groove structure 24 through the discharge port 12. Figures 6-8 The structure of the transmission assembly 20 is schematically shown in the figure. Only the slide groove structure 24 is schematically shown on the upper side of the circumferential transmission member 21. The entire slide groove structure 24 on the outer circumference of the circumferential transmission member 21 is not shown. It is only used to illustrate the assembly relationship between the slide groove structure 24 and the circumferential transmission member 21.

[0046] The flipping assembly 30 includes a flipping structure 31 and a second drive unit 33. The flipping structure 31 includes multiple material cylinder units 311, each of which can be fitted into an inner cylinder. The multiple material cylinder units 311 are arranged in front of all the material discharge ports 12 along the movement direction of the circumferential transmission member 21 and are located to the side of the circumferential transmission member 21. The second drive unit 33 is used to drive the flipping structure 31 to rotate so that the material cylinder units 311 flip to one side of the circumferential transmission member 21 to a first angle state, or flip upward to a second angle state.

[0047] The pushing component 40 includes a pushing frame 41 and a third driving unit 42. The third driving unit 42 is used to drive the pushing frame 41 to move. When the material cylinder unit 311 is flipped to the first angle state, the third driving unit 42 can drive the pushing frame 41 to move to push the inner cylinder on the corresponding slide structure 24 into each material cylinder unit 311.

[0048] The gripping assembly 50 includes a gripper 51 and a drive device; the gripper 51 is capable of gripping or releasing the inner cylinder; the drive device is used to drive the gripper 51 to move to the position of the material cylinder unit 311 to grip the inner cylinder in the material cylinder unit 311 when the material cylinder unit 311 is flipped to the second angle state, or to drive the gripper 51 to move to the position of the fireworks launcher 70 to align the gripped inner cylinder with the launch hole 71 of the fireworks launcher 70 and release it into the launch hole 71 of the fireworks launcher 70.

[0049] The second drive unit 33 can be configured as an electric device, pneumatic device, etc., specifically a cylinder, electric cylinder, motor, etc. A row of material cylinder units 311 is provided on the flipping structure 31. The second drive unit 33 can drive the flipping structure 31 to rotate, causing the material cylinder units 311 to flip to a first angle state and a second angle state. In one embodiment of this application, the first angle state is a horizontal state, and the second angle state is a vertical state. This setting will be used as an example for the following explanation.

[0050] refer to Figure 6 The second drive unit 33 drives the barrel unit 311 to flip to the first angle state (horizontal state) on one side of the circumferential transmission member 21. At this time, the third drive unit 42 drives the pusher frame 41 to move, so that the pusher frame 41 pushes the inner cylinder on the corresponding slide structure 24 into each barrel unit 311. Figure 6 In the structure shown, the pusher frame 41 is equipped with multiple push plates, which are aligned with multiple sliding groove structures 24, thereby enabling the materials in the multiple sliding groove structures 24 to be pushed into each material cylinder unit 311 simultaneously. Additionally, the third drive unit 42 can be configured as an electric device, pneumatic device, etc., specifically a cylinder, electric cylinder, etc.

[0051] refer to Figure 7 The second drive unit 33 drives the material cylinder unit 311 to rotate upward to the second angle state (vertical state). At this time, the gripper 51 of the gripping assembly 50 can move to the position of the material cylinder unit 311 to grip the inner cylinder in the material cylinder unit 311. After gripping the inner cylinder, the gripper 51 of the gripping assembly 50 moves to the position of the fireworks launcher 70 to align the gripped inner cylinder and release it into the launch hole 71 of the fireworks launcher 70.

[0052] The gripping assembly 50 includes a gripper 51 and a drive device. The drive device is used to drive the gripper 51 to move in space, so that the gripper 51 can move to the position of the feed cylinder unit 311 and the position of the fireworks launcher 70. The drive device can be composed of multiple directional moving units, which are stacked and assembled together to jointly drive the gripper 51 to move in space.

[0053] refer to Figure 2 In one embodiment of this application, the driving device includes an x-direction moving unit 52, a y-direction moving unit 53, and a z-direction moving unit 54. The x-direction moving unit 52 is used to drive the gripper 51 to move along the x-direction, the y-direction moving unit 53 is used to drive the gripper 51 to move along the y-direction, and the z-direction moving unit 54 is used to drive the gripper 51 to move along the z-direction. The x-direction, y-direction, and z-direction are perpendicular to each other, and the z-direction is a vertical direction. Figure 2 The x, y, and z directions are shown, where the x and y directions are two mutually perpendicular directions in the horizontal plane, and both are perpendicular to the z direction. Figure 2 In the structure shown, the y-direction moving unit 53 is mounted on a fixed structure, the x-direction moving unit 52 is mounted on the y-direction moving unit 53, the z-direction moving unit 54 is mounted on the x-direction moving unit 52, and the gripper 51 is mounted on the z-direction moving unit 54. Thus, the movements of the x-direction moving unit 52, the y-direction moving unit 53, and the z-direction moving unit 54 can be superimposed to drive the gripper 51 to move in space. Furthermore, in a specific technical solution, the x-direction moving unit 52, the y-direction moving unit 53, and the z-direction moving unit 54 are all linear modules.

[0054] The gripper 51 is capable of gripping or releasing the inner cylinder. The gripper 51 can be configured as a clamping gripper, an adsorption gripper, a bionic / flexible gripper, etc.

[0055] refer to Figure 4 In one embodiment of this application, the gripper 51 includes a first clamping structure 511, a second clamping structure 512, and a fourth driving unit 513. The fourth driving unit 513 is used to drive the first clamping structure 511 and / or the second clamping structure 512 to move, so that the first clamping structure 511 and the second clamping structure 512 can move closer to each other to clamp or move further apart to release the inner cylinder. The fourth driving unit 513 can be configured as an electric device, a pneumatic device, etc., specifically a cylinder, an electric cylinder, etc. When the fourth driving unit 513 drives the first clamping structure 511 and the second clamping structure 512 to move closer to each other, the first clamping structure 511 and the second clamping structure 512 can clamp the inner cylinder between them; when the fourth driving unit 513 drives the first clamping structure 511 and the second clamping structure 512 to move further apart, the first clamping structure 511 and the second clamping structure 512 can release the inner cylinder between them. Figure 4In the structure shown, the fourth drive unit 513 is a cylinder, and the second clamping structure 512 is connected to the piston rod of the cylinder. When the piston rod of the cylinder extends or retracts, it can drive the second clamping structure 512 to move closer to or further away from the first clamping structure 511.

[0056] refer to Figure 5 In one embodiment of this application, the gripper includes a clamping base 514 and a plurality of actuating units 515. The plurality of actuating units 515 are arranged side-by-side on the side of the clamping base 514, and each actuating unit 515 can cooperate with the clamping base 514 to clamp several inner cylinders. It should be noted that each actuating unit 515 includes a driving device and can operate independently. Each actuating unit 515 can cooperate with the clamping base 514 to clamp one or more inner cylinders. Figure 5 In the illustrated structure, each actuating unit 515 includes a cylinder, and each actuating unit 515 can clamp one inner cylinder. During operation, since the gripper is equipped with multiple actuating units 515, each actuating unit 515 can independently clamp one or more inner cylinders. The inner cylinders clamped by different actuating units 515 can be released into launch holes at different positions, or even into different firework launchers, thus making it more flexible in use.

[0057] In one embodiment of this application, the inner cylinder filling device further includes an ejection assembly 60; the ejection assembly 60 includes a lifting frame 61 and a fifth drive unit 62; the fifth drive unit 62 is used to drive the lifting frame 61 to move; when the cylinder unit 311 is flipped to the second angle state, the fifth drive unit 62 drives the lifting frame 61 to lift the inner cylinder in each cylinder unit 311 from the bottom upwards, so that the upper part of the inner cylinder extends out of the cylinder unit 311 so that it can be grasped by the gripper 51.

[0058] The fifth drive unit 62 can be configured as an electric device, a pneumatic device, etc., specifically a cylinder, an electric cylinder, etc. When the material cylinder unit 311 is flipped to the second angle state, the fifth drive unit 62 can drive the lifting frame 61 to push the inner cylinder in each material cylinder unit 311 upward, so that the upper part of the inner cylinder extends outside the material cylinder unit 311, and the gripper 51 can grab the upper part of the inner cylinder.

[0059] In one embodiment of this application, when the material cylinder unit 311 is flipped to a first angle state, the spacing distribution of the material cylinder unit 311 is adjusted to the first state, consistent with the spacing distribution of the chute structure 24 on the circumferential transmission member 21; when the material cylinder unit 311 is flipped to a second angle state, the spacing distribution of the material cylinder unit 311 is adjusted to the second state, consistent with the spacing distribution of the launch holes on the fireworks launcher to be filled; wherein, the first state is different from the second state. In this scheme, the spacing distribution of the material cylinder unit 311 is adjustable, and the inner cylinder can be transferred and filled even when the spacing distribution of the chute structure 24 and the spacing distribution of the launch holes are different. When the spacing distribution of the launch holes changes, the spacing distribution of the material cylinder unit 311 can also be controlled to adapt to it.

[0060] In one embodiment of this application, reference is made to Figure 6 and Figure 7 The flipping structure 31 also includes a rotating seat 313; all the barrel units 311 are slidably mounted on the rotating seat 313, and the sliding direction of the barrel units 311 is consistent with the movement direction of the circumferential transmission member 21.

[0061] refer to Figure 8 The flipping assembly 30 also includes a guide seat 32; the guide seat 32 is provided with multiple guide structures, each corresponding to a material cylinder unit 311; the guide structures and the material cylinder unit 311 form a guiding fit to guide the movement of the material cylinder unit 311. It should be understood that the guide structures can be designed in various forms, such as guide grooves, guide bodies, etc., and can be used to guide the movement of the material cylinder unit 311.

[0062] When the second driving unit 33 drives the rotating seat 313 to rotate, the rotating seat 313 drives the material cylinder unit 311 on it to rotate synchronously. At least part of the guide structure guides the material cylinder unit 311 to slide relative to the rotating seat 313, thereby changing the interval between the corresponding material cylinder units 311. When the material cylinder unit 311 is flipped to the first angle state, the spacing distribution of the material cylinder unit 311 is slidably adjusted to the first state. When the material cylinder unit 311 is flipped to the second angle state, the spacing distribution of the material cylinder unit 311 is slidably adjusted to the second state. In the first state, the spacing distribution of the material cylinder unit 311 is consistent with the spacing distribution of the sliding groove structure 24 on the circumferential transmission member 21. In the second state, the spacing distribution of the material cylinder unit 311 is consistent with the spacing distribution of the launching holes on the fireworks launching seat to be filled. The first state and the second state may be the same or different.

[0063] The cylinder unit 311 is slidably mounted on the rotating base 313. The guide structure forms a guiding engagement with the cylinder unit 311. Therefore, when the rotating base 313 rotates, the guide seat 32 can control the position of each cylinder unit 311 on the rotating base 313. Specifically, when the rotating base 313 drives the cylinder units 311 on it to rotate synchronously, part or all of the guide structure guides the cylinder units 311 to slide relative to the rotating base 313, thereby changing the spacing between the corresponding cylinder units 311. Therefore, when the cylinder unit 311 is flipped to the first angle state, the spacing distribution of the cylinder units 311 is slidably adjusted to the first state, consistent with the spacing distribution of the chute structure 24 on the circumferential transmission member 21; when the cylinder unit 311 is flipped to the second angle state, the spacing distribution of the cylinder units 311 is slidably adjusted to the second state, consistent with the spacing distribution of the launch holes on the fireworks launcher to be filled. Therefore, the equipment can transfer and fill the inner cylinder even when the spacing distribution of the chute structure 24 and the spacing distribution of the launch holes are the same or different.

[0064] The guiding structure is a guide groove or guide body to guide the barrel unit 311 to move along its extension direction; all the guiding structures extend about the rotation direction of the rotating seat 313 to guide the barrel unit 311 to rotate; at least some of the guiding structures have a sliding direction offset while extending about the rotation direction of the rotating seat 313, so that the corresponding barrel unit 311 slides relative to the rotating seat 313 when rotating.

[0065] refer to Figure 8 When the guiding structure is a guide groove 321, the barrel unit 311 is equipped with rollers 312 that are adapted to the guide groove 321; when the barrel unit 311 moves, the rollers 312 on the barrel unit 311 move in the corresponding guide groove 321 to guide the movement of the barrel unit 311. Figure 8 In the structure shown, the engagement between the roller 312 of the feed cylinder unit 311 and the guide groove 321 guides the feed cylinder unit 311 to rotate. Figure 8 In the middle, a portion of the guide groove 321 has an offset in the sliding direction, thereby causing the corresponding portion of the barrel unit 311 to slide relative to the rotating seat 313 when rotating. Figure 8 In some embodiments, the guide grooves 321 are not offset in the sliding direction, so that the corresponding parts of the barrel units 311 do not slide relative to the rotating seat 313 when rotating. It should be understood that during rotation, some barrel units 311 will slide while others will not, which can change the spacing distribution of the barrel units 311. In other embodiments, all guide grooves 321 are offset in the sliding direction, so that all barrel units 311 slide relative to the rotating seat 313 when rotating, thereby changing the spacing distribution of the barrel units 311.

[0066] This application also provides a fireworks production device, including the aforementioned inner cylinder filling device. The inner cylinder filling device includes a hopper 10, a conveying assembly 20, a tilting assembly 30, a pushing assembly 40, and a gripping assembly 50. For a more detailed description, please refer to the preceding section on the inner cylinder filling device; it will not be repeated here.

[0067] In summary, in this application, the hopper is used to load the inner cylinder, and its bottom is provided with a discharge hole. As the circumferential transmission component moves, the various chute structures on its outer periphery sequentially pass below the discharge hole to receive the inner cylinder falling from it. When the cylinder unit flips to the first angle state, the pushing component can push the inner cylinder on the corresponding chute structure into each cylinder unit. When the cylinder unit flips to the second angle state, the gripper of the grasping component can move to the position of the cylinder unit to grasp the inner cylinder in the cylinder unit, and move it to the position of the fireworks launcher to release it into the launch hole of the fireworks launcher. The above-mentioned inner cylinder filling equipment has a relatively simple structure, low cost, better flexibility in use, and easier control over the quantity and position of the inner cylinders loaded.

[0068] Furthermore, since the spacing of the cylinder units is adjustable, the inner cylinder can be transferred and filled even when the spacing distribution of the chute structure and the spacing distribution of the launching holes differ. When the spacing distribution of the launching holes changes, the spacing distribution of the cylinder units can also be controlled to adapt accordingly. In some technical solutions, guide seats are used to control the spacing distribution of the inner cylinder; simply using different guide seats can adapt to fireworks launching stands with various hole spacing distributions.
