Description

Technical Field

[0001] The present application relates to the technical field of fireworks production equipment, and in particular to an inner tube device for combined fireworks. Background Art

[0002] The inner tube is the core component of a firework, responsible for housing the pyrotechnic composition and achieving lift, explosion, and display effects during ignition. Typically, the inner tube cake is the basic unit of firework production. The inner tube cake is composed of multiple inner tubes held together by cable ties, forming a hexagonal shape.

[0003] Most existing fireworks inner tube loading equipment uses a single hopper to load fireworks inner tubes, and uses manual loading to unbundle the inner tubes and load them into the hopper. For example, Chinese patent CN201721196363.2 discloses a deflection lower tube device for a double-shot fireworks automatic forming machine, which includes a lower tube hopper, a base, and a tube pushing mechanism. The discharge port of the lower tube hopper is provided with a deflection and pushing mechanism corresponding to the tube pushing mechanism. The tubes stacked in the lower tube hopper are pushed from the discharge port to the deflection and pushing mechanism by the tube pushing mechanism. The deflection and pushing mechanism arranges and deflects the multiple tubes and pushes them to the tube conveying device of the double-shot fireworks automatic forming machine. However, when the above-mentioned fireworks inner tube loading equipment is used, on the one hand, the inner tube configuration is not flexible enough, and only one type of inner tube can be loaded in the hopper. On the other hand, the operator needs to be close to the hopper to load the inner tube, and the cable tie of the inner tube cake needs to be manually removed before the inner tube is placed in the hopper. The degree of automation is low, and the safety of the operator cannot be guaranteed. Utility Model Content

DETAILED DESCRIPTION

[0028] The following are specific embodiments of the present application and, in conjunction with the accompanying drawings, further description of the technical solutions of the present application is provided, but the present application is not limited to these embodiments. In the following description, specific details such as specific configurations and components are provided solely to assist in a comprehensive understanding of the embodiments of the present application. Therefore, it should be clear to those skilled in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope of protection of the present application. In addition, for clarity and brevity, descriptions of known functions and configurations have been omitted.

[0029] It should be noted that, unless there is any conflict, the embodiments and features in the embodiments of this application can be combined with each other.

[0030] The present application provides a combined fireworks inner tube device for loading the inner tube into the fireworks launch tube. Figure 1-Figure 3 The inner tube equipment includes multiple silos 31 and a loading assembly; wherein the multiple silos 31 are distributed in multiple different positions; the silo 31 is provided with a trough for accommodating the inner tube, and is provided with a feed port and a drop port; the loading assembly includes a gripper 10 and an action mechanism 20; the action mechanism 20 can drive the gripper 10 to move to grab the inner tube cake Q, and can transfer the inner tube to any silo 31 for drop-off.

[0031] The loading assembly is used for automated loading. The actuator 20 drives the gripper 10 to move, allowing the gripper 10 to grasp the inner tube cake. After grasping the inner tube cake, the loading assembly further transfers the inner tube cake to one of the silos 31. During the fireworks production process, the inner tube cakes are loaded into the outer tube of the fireworks body. Firework inner tube cakes can be categorized into different types based on the desired firing effect (e.g., color, sound). This structural design allows different silos 31 to hold different types of inner tube cakes, allowing the loading assembly to flexibly allocate the inner tube cakes in each silo, enhancing production flexibility. Furthermore, the loading assembly can grab inner tube cakes and transfer them to each silo, enabling automated loading of each silo. This provides a high degree of automation and eliminates the need for manual close-up unpacking and loading, enhancing safety. Furthermore, the multiple silos are located in different locations, minimizing the risk of accidents.

[0032] The motion mechanism 20 can drive the gripper 10 to move along the x-axis, y-axis, and z-axis directions. The x-axis and y-axis directions are perpendicular to each other, and the z-axis is the vertical direction. Therefore, the motion mechanism 20 can drive the gripper 10 to move along a set trajectory in space, allowing the gripper 10 to move to a predetermined position to grasp the inner tube cake.

[0033] In one embodiment of the present application, the action mechanism 20 includes a first drive unit 21, a second drive unit 22, and a third drive unit 23; wherein the first drive unit 21 is used to drive the gripper 10 along the x-axis direction; the second drive unit 22 is used to drive the gripper 10 along the y-axis direction; and the third drive unit 23 is used to drive the gripper 10 along the z-axis direction.

[0034] Specifically, the first drive unit 21, the second drive unit 22, and the third drive unit 23 are used to drive the gripper 10 to move in the x-axis direction, the y-axis direction, and the z-axis direction, respectively, so that the gripper 10 can move freely in space to grab the inner tube cake. Figure 1 and Figure 2 In the structure shown, two first drive units 21 are arranged at intervals; the second drive unit 22 is mounted on the two first drive units 21 and can be driven by the first drive unit 21 to move in the x-direction; the third drive unit 23 is mounted on the second drive unit 22 and can be driven by the second drive unit 22 to move in the y-direction; the gripper 10 is mounted on the lower end of the third drive unit 23 and can be driven by the third drive unit 23 to move in the z-axis direction; in this way, the gripper 10 is located at the driving end and can superimpose the displacements generated by the first drive unit 21, the second drive unit 22, and the third drive unit 23 in the x-axis direction, the y-axis direction, and the z-axis direction, respectively, to achieve spatial movement. In one specific embodiment, the x-axis drive unit, the y-axis drive unit, and the z-axis drive unit are all linear modules, which can be specifically configured as ball screw modules, synchronous belt modules, linear motor modules, gear rack modules, etc. It should be understood that linear modules are within the scope of the prior art and will not be described in detail here.

[0035] In one embodiment of the present application, the inner tube equipment further comprises a first conveying mechanism 40. The first conveying mechanism 40 is equipped with a plurality of inner tube trays 41 for placing inner tube cakes. The first conveying mechanism 40 is capable of cyclically conveying the inner tube trays 41 between a first position and a second position. The actuating mechanism 20 is capable of driving the gripper 10 to a second position to grasp the inner tube cakes on the inner tube trays 41. In this design, the inner tube trays 41 are used to hold the inner tube cakes. Multiple types of inner tube cakes can be placed on the inner tube trays 41 as needed. Accordingly, the loading assembly can sequentially load the various types of inner tube cakes into the respective hoppers 31. In one specific embodiment, the first conveying mechanism 40 is a chain mechanism, with the inner tube trays 41 secured to the chain. As the chain mechanism operates, the inner tube trays 41 cyclically move between the first and second positions. Therefore, the conveying loop of the first conveying mechanism 40 allows the inner tube cakes to be continuously conveyed from the first position to the second position for loading and conveying. This design is suitable for automated loading equipment for firework inner tubes, facilitates operator isolation, and improves operator safety.

[0036] It should be noted that an inner tube cake is a bundle of inner tubes, a collection of multiple inner tubes. In the fireworks production process, inner tubes often appear in the form of inner tube cakes. The loading assembly loads the inner tube cakes individually, and the gripper 10 can grab one or more inner tube cakes at a time. Specifically, an inner tube cake contains N inner tubes. When the gripper 10 grabs one inner tube cake, it is equivalent to grabbing N inner tubes, and these N inner tubes can be transferred simultaneously to a silo.

[0037] Schematically, the gripper 10 can grasp inner drum cakes from different positions on the inner drum tray 41 and transfer them to the corresponding silo 31. Specifically, the inner drum tray 41 is provided with loading positions A1, A2, ..., and An, and the silos include silos B1, B2, ..., and Bn. A corresponding relationship is established between loading positions Ai and silos Bi, where i can be 1, 2, ..., or n. The gripper 10 can grasp inner drum cakes from loading positions Ai and transfer them to the corresponding silo Bi. During loading, to meet diverse inner drum filling requirements, the inner drums in each silo require flexible configuration. To configure the corresponding types of inner drum cakes in each silo (silo B1, B2, ..., and Bn) as needed, the operator can place multiple types of inner drum cakes in the order required in loading positions A1, A2, ..., and An. It should also be noted that the types of firework inner tubes are divided according to the firing effect (e.g., color, sound). It should be understood that the above-mentioned correspondence (the correspondence between the inner tube cakes on the inner tube tray 41 and the silo 31) is only a schematic correspondence.

[0038] Continue to refer Figure 4 and Figure 5 In one embodiment of the present application, the inner drum device further includes a second conveying mechanism 50 and multiple transfer modules 51. The second conveying mechanism 50 is capable of operating in a set conveying direction. The transfer modules 51 are provided with multiple rows of loading holes. The multiple transfer modules 51 are sequentially arranged on the second conveying mechanism 50 at intervals and can be driven by the second conveying mechanism 50 to move in the conveying direction. As the second conveying mechanism 50 operates, each row of loading holes in the transfer modules 51 can sequentially receive inner drums from different silos 31. The inner drums of the silos 31 are loaded into the transfer modules 51, with each silo 31 corresponding to a row of loading holes in the transfer modules 51. As the second conveying mechanism 50 operates, each row of loading holes in the transfer modules 51 can receive inner drums from multiple different silos.

[0039] Furthermore, each silo 31 is configured as a corresponding inner tube output device 30; the inner tube output device 30 is capable of delivering a row of inner tubes at a time to be loaded into a row of loading holes on the transfer module 51. As the second conveying mechanism 50 operates, the loading holes of the transfer module 51 on it are sequentially aligned with the inner tube output devices 30 at different positions. Specifically, the inner tube output device 30 comprises a silo 31, wherein the inner tubes in the silo 31 can fall onto a chute, and a pushing mechanism can push the inner tubes one row at a time into the row of loading holes. It should be understood that the inner tube output device 30 is a conventional component of an inner tube equipment, used to push the inner tubes row by row into the transfer module. It typically includes a hopper, a chute, and a pushing mechanism. When the inner tubes in the hopper fall onto the chute, they are then pushed into the transfer module by the pushing mechanism. In this application, the inner tube output device 30 can be designed in various structural forms as needed.

[0040] Exemplarily, N rows of loading holes are provided on the transfer module 51 , the first row of loading holes is filled by the first inner cylinder output device 30 , the second row of loading holes is filled by the second inner cylinder output device 30 , and so on, the Nth row of loading holes is filled by the Nth inner cylinder output device 30 .

[0041] Five inner cylinder output devices 30 are arranged above the second conveying mechanism 50, and nine rows of loading holes are arranged on the transfer module 51. As the second conveying mechanism 50 operates, the first inner cylinder output device 30 fills the first row of loading holes on the transfer module 51, the second inner cylinder output device 30 fills the second row of loading holes on the transfer module 51, the third inner cylinder output device 30 fills the third row of loading holes on the transfer module 51, the fourth inner cylinder output device 30 fills the fourth row of loading holes on the transfer module 51, and the fifth inner cylinder output device 30 fills the fifth row of loading holes on the transfer module 51. At this time, after the five inner cylinder output devices 30 complete one round of loading, the first five rows (first to fifth rows) of loading holes on the transfer module 51 have been filled. The remaining four rows (sixth to ninth rows) of loading holes on the transfer module 51 can be filled in the next round. As the second conveying mechanism 50 operates, the first inner drum output device 30 fills the sixth row of loading holes on the transfer module 51, the second inner drum output device 30 fills the seventh row of loading holes on the transfer module 51, the third inner drum output device 30 fills the eighth row of loading holes on the transfer module 51, and the fourth inner drum output device 30 fills the ninth row of loading holes on the transfer module 51. At this point, after two rounds of filling, all nine rows of loading holes on the transfer module 51 are filled. It should be understood that the above filling scheme is merely exemplary; multiple inner drum output devices 30 can fill multiple rows of loading holes in a variety of ways.

[0042] Based on the above exemplary filling scheme, it can be determined that when the inner cylinders contained in the inner cylinder output devices 30 are of different types, the transfer module 51 will correspondingly contain multiple types of inner cylinders after the filling is completed.

[0043] In one embodiment of the present application, the distribution intervals of the multiple inner cylinder output devices 30 are adapted to the distribution intervals of the transfer modules 51 on the second conveying mechanism 50, so that each inner cylinder output device 30 can be simultaneously loaded and aligned with the transfer modules 51 at different positions on the second conveying mechanism 50.

[0044] In one embodiment of the present application, when each inner cylinder output device 30 is respectively aligned with the transfer modules 51 at different positions on the second conveying mechanism 50 , each inner cylinder output device 30 is respectively aligned with the loading holes in different rows on the transfer module 51 .

[0045] In one embodiment of the present application, the inner tube device further includes a grabbing mechanism 60, which is used to grab the transfer unit of the second conveying mechanism 50 and move it above the fireworks launch tube W, and align the loading hole of the transfer module 51 with the fireworks launch tube W, so as to load the fireworks inner tube blanks in the loading hole into the fireworks launch tube W. It should be understood that

[0046] The gripping mechanism includes a modular gripper and a moving device. The modular gripper is used to grasp the transfer unit, while the moving device drives the modular gripper. This mechanism typically includes multi-directional motion mechanisms, which can be configured based on the specific application. It should be understood that the moving device is a common mechanical device in the prior art and will not be described in detail here.

[0047] Based on the above analysis, it can be seen that the inner tube equipment provided in this application can flexibly configure the inner tube in the firework launch tube, has good production flexibility, can reduce manpower participation, isolate workers, and is safer.
