A parallel feeding and stacking device for the cylinder and spacers of a fireworks assembly machine.

Abstract

This utility model discloses a parallel feeding and stacking device for cylinders and spacers in a fireworks assembly machine. A lifting receiving platform connects front and back to the worktable and left and right to the spacer feeding mechanism. A transition plate, positioned between the receiving platform and the worktable, performs a linear telescopic movement. The extended transition plate is located above the receiving platform and connected to the worktable. A gap exists between the transition plate and the receiving platform below, allowing spacers to pass through. Spacers fed by the feeding mechanism are fed onto the cylinders at the receiving platform through this gap. The retracted transition plate moves away from the receiving platform. Both cylinder feeding and spacer feeding can be performed simultaneously. Then, the transition plate retracts, and the cylinders fall onto the spacers, completing the stacking process. Since both processes occur concurrently within the same timeframe, the total processing time is significantly reduced, improving the processing efficiency of the fireworks assembly machine.

Description

Technical Field

[0001] This utility model relates to a fireworks assembly machine. Background Technology

[0002] The working process of the fireworks assembly machine is as follows: The feeding and unloading system feeds multiple fireworks tubes onto the worktable in the required quantity, arranging them in rows (referred to as tube rows). Then, a pushing device pushes the tube rows from the worktable along a direction parallel to the central axis of the fireworks tubes, conveying them to the punching and insertion station under the clamping of the worktable and conveyor rollers. A moving insertion system, including a lead wire conveying mechanism, completes the punching and insertion process. Next, glue is applied to the fireworks tubes in the tube rows. Driven by the rear tube rows, the front tube rows on the worktable sequentially enter a lifting receiving platform connected to the worktable. The receiving platform descends step by step, receiving and stacking the tube rows one by one. After the glue on each tube row cures, they are bonded together into a block. When the receiving platform reaches its bottom position, the block is pushed off the platform, which then rises and resets to continue the next cycle, stacking multiple tube rows into a block. The working principle is illustrated in Chinese Invention Patent Document—Announcement No.: CN102538597B, Title: A Firework Assembly Machine. Chinese Utility Model Patent Document - Announcement No.: CN223021092U, Title: A Block-shaped Integrated Discharge Device for Irregularly Shaped Combined Fireworks.

[0003] The cylindrical array can be a vertical cylindrical array, or a vertical cylindrical array on the receiving platform can be processed into a non-standard cylindrical array by a non-standard forming mechanism. The working principle of the non-standard forming mechanism can be found in the following patent documents:

[0004] Publication number: CN120313421A, title: A processing device for a combination of firework interval-type irregular tube array;

[0005] Authorization Announcement No.: CN223021097U A forming mechanism for irregularly shaped cylindrical arrays;

[0008] Publication No.: CN116907283A A special-shaped tube forming equipment for special-shaped combined fireworks.

[0009] In a block-shaped assembly, spacers, such as fireproof paper, spacer strips (foam strips or wooden strips), or other spacers, are required between adjacent rows of cylinders. See the following Chinese utility model patent documents:

[0010] Authorization Announcement No.: CN221505824U, Title: A fireproof paper processing device for irregularly shaped combination fireworks;

[0011] Authorization Announcement No.: CN221037115U, Title: A Fireproof Paper Assembly Mechanism for a Fireworks Container Forming System;

[0012] Authorization Announcement No.: CN221859369U, Title: A Fireproof Paper Assembly Mechanism for Fireworks Pot Formation;

[0013] Authorization Announcement No.: CN207147327U, Title: A Spacer Installation Mechanism for Combined Fireworks.

[0014] In existing technology, the worktable and receiving platform are connected front to back, and the feeding mechanism for the spacers is connected left to right to the receiving platform. The cylindrical section pushed out from the worktable enters the receiving platform station from the front to back (referred to as cylindrical section feeding), and the spacers fed by the feeding mechanism enter the same receiving platform station from the left to right (referred to as spacer feeding). They are fed sequentially, one cylindrical section and one spacer, to the receiving platform station for stacking. The drawback is that the cylindrical section and spacer need to be fed into the same station sequentially for stacking. The feeding of one workpiece must wait for the other workpiece to be fed in. Since each workpiece requires a certain feeding time, the total time is at least the sum of the two feeding times, thus affecting processing efficiency. Utility Model Content

[0015] To address the aforementioned drawbacks, the technical problem this invention aims to solve is to simultaneously feed both the cylinder and spacer components in a fireworks stacking machine to efficiently complete the stacking process. The technical solution adopted by this invention is a parallel feeding and stacking device for cylinders and spacers in a fireworks stacking machine. This device includes a lifting receiving platform, with a worktable connected to the receiving platform front and rear, and a spacer feeding mechanism connected to the receiving platform left and right. The device is characterized by further including a transition plate, the height of which is between the receiving platform and the worktable. The transition plate is connected to a drive unit for telescopic movement. When extended, the transition plate is positioned above the receiving platform and connected to the worktable; cylinders fed from the worktable land on the transition plate. A gap exists between the extended transition plate and the receiving platform below, through which spacers are fed by the feeding mechanism onto the receiving platform. When retracted, the transition plate is positioned away from the receiving platform.

[0016] The beneficial effect of this utility model is that, by adopting the above technical solution, when the transition plate extends, two tasks can be performed simultaneously: feeding the cylindrical stack onto the transition plate and feeding the spacers. Then, the transition plate retracts, and the cylindrical stack on the transition plate falls onto the spacers, thus completing the stacking process. Since the two tasks are performed concurrently within the same time period, the total time is significantly reduced, improving the processing efficiency of the stacking machine.

[0017] In one embodiment, the transition plate consists of a front transition plate and a rear transition plate located at the front and rear ends of the receiving platform, respectively. The front and rear transition plates are connected to driving components to perform telescopic movements. When extended, both the front and rear transition plates move towards the receiving platform and move closer to each other. The front end of the cylindrical tubes delivered from the worktable lands on the front transition plate, and the rear end of the cylindrical tubes lands on the rear transition plate. Compared to an integral transition plate, this design effectively shortens the retraction time of the transition plate.

[0018] When the firework tubes delivered from the workbench land on the transition plate, the glue has not yet cured, and the tubes are only connected by leads, resulting in a loose arrangement of the tubes. Therefore, in one embodiment, a baffle is provided at the rear end of the firework tubes on the transition plate, and a pusher is provided at the front end. The pusher, connected to a drive unit, moves linearly back and forth. As the pusher moves forward, it pushes the front end of the firework tubes, causing the rear ends of each tube to abut against the baffle. This completes the arrangement of the firework tubes, ensuring a neat and orderly configuration.

[0019] The spacer fed by the feeding mechanism is fed into the cylinder at the receiving platform station through the passage gap. When the spacer is fireproof paper, the fireproof paper may encounter resistance as it moves across the uneven cylinder. Therefore, in one embodiment, a slide rail is provided below the transition plate, moving synchronously with the transition plate, with the passage gap between the transition plate and the slide rail. The fireproof paper fed by the feeding mechanism moves smoothly along the slide rail without obstruction, ensuring smooth and reliable feeding.

[0047] See appendix Figure 1-9 This illustrates a specific structure of the parallel feeding and stacking device for the cylinder and spacers in the fireworks assembly machine of this utility model. The work performed by the example assembly machine is as follows:

[0048] The upright tube arrays 2 on the worktable 1 are pushed out in rows along a direction parallel to the central axis of the firework tubes. After drilling and insertion, glue is applied. Driven by the rear tube arrays, the front tube arrays on the worktable 1 sequentially enter the lifting receiving platform 10 connected to the worktable 1. On the receiving platform 10, the upright tube arrays 2 are processed into fan-shaped tube arrays 3 by the irregular forming mechanism 7. In the example irregular forming mechanism 7, the pitch-changing mechanism drives the upper ends of each firework tube in the upright tube array 2 to swing in an irregular (fan-shaped) distribution through the tube positioning component (also called the guide tube component) - ball head core rod 17, thus obtaining the fan-shaped tube arrays 3.

[0049] The paper roll 5 of the fireproof paper assembly mechanism is fed into the paper strip 6 with easy-tear seams and inserted between the upper and lower rolls. The receiving platform 10 descends step by step to receive the rolls one by one. When the pressing mechanism 13 presses down on the fan-shaped rolls 3 and descends synchronously with the receiving platform 10, it tears the easy-tear seams of the paper strip 6 to obtain the spacer—fireproof paper 15. After the glue on each roll cures, it is glued together to form a block 4. After the receiving platform 10 reaches the bottom position, the block 4 is pushed out of the receiving platform 10 by the pushing mechanism 11. At the tape application station 9, the block 4 is wrapped with tape for further reinforcement, and then sent out by the discharge conveyor belt 8. These working processes have been fully disclosed in the prior art and will not be described in detail here.

[0050] The parallel feeding and stacking device for the cylinder and spacer of the fireworks assembly machine includes a lifting receiving platform 10. The worktable 1 is connected to the receiving platform 10 at the front and back. The feeding mechanism of the spacer - fireproof paper 15 is connected to the receiving platform 10 at the left and right. The paper strip 6 with easy-tear seams that is unwound from the paper roll 5 is fed into the receiving platform 10.

[0051] The device also includes a transition plate, the height of which is between the receiving platform 10 and the worktable 1; that is, the height of the transition plate is lower than the worktable 1 and higher than the receiving platform 10. The transition plate is connected to a driving component for telescopic movement. In the example, the transition plate consists of a front transition plate 14 and a rear transition plate 12 located at the front and rear ends of the receiving platform 10, respectively. The front transition plate 14 and the rear transition plate 12 are located on the same horizontal plane and are connected to a front transition plate cylinder 19 and a rear transition plate cylinder 20, respectively, for telescopic movement. When extended, both the front transition plate 14 and the rear transition plate 12 move towards the receiving platform 10 and are in a state of mutual approach.

[0052] Both the extended front transition plate 14 and the rear transition plate 12 are located above the receiving platform station. The rear transition plate 12 connects to the workbench 1. The front end of the upright cylindrical bar 2 delivered from the workbench 1 lands on the front transition plate 14, and the rear end of the cylindrical bar lands on the rear transition plate 12. Lifting protective rods 31 can be installed on both sides of the cylindrical bar. When the cylindrical bar lands on the transition plate, the protective rods 31 are in a lowered state to provide limit protection. After the cylindrical bar lands on the transition plate, the protective rods 31 rise to avoid movement interference.

[0053] The receiving platform workstation refers to the space on the receiving platform 10 where the cylindrical bar is placed.

[0054] The extended front transition plate 14 and / or rear transition plate 12 have a gap between them and the receiving platform station below, through which a spacer—fireproof paper 15—passes. The paper strip 6 is fed through this gap onto the fan-shaped cylinder 3 of the receiving platform station. When the basin assembly machine is first started, there is no cylinder 3 on the receiving platform station of the receiving platform 10; therefore, the paper strip 6 is fed directly onto the receiving platform station at this time.

[0055] Because the fireproof paper 15 may encounter obstacles when advancing on the uneven fan-shaped cylindrical strip 3, in this example, a slide 16 that moves synchronously with the rear transition plate 12 is provided below it, with the aforementioned passage gap 22 between the rear transition plate 12 and the slide 16. The side of the paper strip 6 advances smoothly on the slide 16 without obstruction, ensuring smooth and reliable feeding.

[0056] The retracted transition plate moves away from the receiving platform station. In the example, the front transition plate 14 retracts forward until it is no longer in contact with the front end of the fan-shaped cylindrical array 3, and the rear transition plate 12 retracts backward until it is no longer in contact with the rear end of the fan-shaped cylindrical array 3, so that the fan-shaped cylindrical array 3 can fall onto the fireproof paper 15.

[0057] When the upright tube array 2 delivered from the workbench 1 lands on the transition plate, the glue has not yet cured, and the firework tubes are only connected by leads. The individual firework tubes in the array are still loose, which may result in uneven arrangement. To address this, in this example, the rear end of the upright tube array 2 on the rear transition plate 12 is equipped with a baffle 18, and the front end of the upright tube array 2 on the front transition plate 14 is equipped with a pusher. The pusher is connected to a drive unit and moves back and forth in a straight line. When the pusher moves backward, it pushes the front end of the upright tube array 2, causing the rear ends of each firework tube to abut against the baffle 18. This completes the arrangement of the tube array, making it neat. In this example, the tube array is a fan-shaped tube array 3. When processing the upright tube array 2 into a fan-shaped tube array 3, the ball-head core rod 18 needs to move backward to contact the front end of the firework tubes in order to drive the upper ends of each firework tube in the upright tube array 2 to swing open. After opening, it needs to move forward to reset and disengage from the firework tubes. Therefore, the work of pushing the workpiece can be accomplished by the ball head core rod 18 (or a similar cylindrical positioning part).

[0058] Using the above technical solution, when the transition plate extends, two tasks can be performed simultaneously: Task A: the upright cylindrical stack 2 is fed onto the transition plate; Task B: the fireproof paper 15 is fed in. Then the transition plate retracts, and the fan-shaped cylindrical stack 3 on the transition plate falls onto the fireproof paper 15, thus completing the stacking process. Because the transition plate is designed to allow passage through gaps, the two tasks can be performed in parallel within the same time period without interfering with each other, thereby significantly reducing the total time and improving the processing efficiency of the stacking machine.

[0059] Since task B takes longer than task A, in this example, during the time allotted for task B, not only can task A be completed, but the work of having the upper ends of each firework tube in the upright tube array 2 swing in a fan-shaped distribution, driven by the ball-head core rod 17, can also be completed simultaneously. Therefore, the processing efficiency is significantly improved. Comparative experimental data under the same working conditions shows that the processing efficiency of the assembly machine using this invention is approximately 7000 firework tubes / hour (one firework tube is considered one firework tube). In contrast, the processing efficiency of existing assembly machines is approximately 5000 firework tubes / hour.

[0060] The embodiments of the present invention disclosed above are merely illustrative of the present invention. The embodiments do not describe all details exhaustively, nor do they limit the present invention to only the specific implementations described. Obviously, many modifications and variations can be made based on the content of this specification, such as:

[0061] Other implementations, such as Figure 10 As shown, the transition plate can be a single, integral transition plate 23. The integral transition plate 23 is a single, unified plate structure, not divided into front and rear parts. During extension and retraction, the entire plate moves in the front / back or left / right directions to enter / exit the receiving platform station. This can also be achieved. However, compared to the above embodiment, the extension and retraction stroke may be increased.

[0062] Other implementations, such as Figure 11 As shown, the slide rail 16 is not required under the transition plate. It can be used with rigid fireproof paper or spacer strips, especially spacer strips made of foam or wood. It should be noted that without the slide rail 16, the clearance is formed by the distance between the bottom of the transition plate and the receiving platform station or the cylindrical trays on the station. When the potter's bowl assembly machine is first started, there are no cylindrical trays on the receiving platform station of the receiving platform 10; during operation, cylindrical trays are fed into the receiving platform station and gradually stacked. However, because the receiving platform 10 is constantly descending, a clearance of a corresponding height can always be maintained.

[0063] In other embodiments, the cylinder bank can always be an upright cylinder bank, without the need to process it into an irregular (fan-shaped) cylinder bank. In this case, it may not be necessary to assemble the irregular forming mechanism 7, and therefore there is no pitch changing mechanism or cylinder positioning component—the ball-head core rod 17. At this time, as... Figure 12 As shown, the corresponding flat-pushing workpiece can be a baffle 24 whose width corresponds to that of the upright tube array 2. The baffle 24 is connected to the driving component and moves back and forth in a linear reciprocating motion. When moving backward, it flat-pushes the front end of the upright tube array 2 so that the rear end of each firework tube abuts against the baffle 18. This can also complete the arrangement of the tube array, making it neat and orderly. The driving component connected to the baffle 24 can be a front transition plate cylinder 19, or a separate driving component can be provided.

[0064] In other embodiments, the spacers can be foam strips or wooden strips. The spacers can be manually or automatically fed onto the drum of the lifting platform. The spacing can be adjusted as needed. An example of an automatically fed spacer assembly machine is... Figure 13-17 As shown, the difference from the above embodiment is that the spacer bar feeding mechanism 25 replaces the fireproof paper assembly mechanism, and the spacer bar 26 is inserted between the upper and lower cylinder rows. In the example, the cylinder rows are vertical cylinder rows 2, but in other embodiments, they can also be fan-shaped cylinder rows 3.

[0065] The spacer bar feeding mechanism 25 includes a spacer bar unloading rack 27 for storing spacer bars 26. A push rod 28 pushes the spacer bars 26 at the bottom of the unloading rack 27 to the right. The spacer bars 26 are then fed sequentially through the glue application wheel assembly 29 and the feeding chute 30 into the receiving platform station, located on the cylindrical array below the front and rear transition plates. After the front and rear transition plates retract, the upper cylindrical array falls, causing the spacer bars 26 to be glued and fixed between the upper and lower cylindrical arrays. The rest is the same as in the aforementioned embodiment and will not be described again.

[0066] In summary, the embodiments described in detail in conjunction with the accompanying drawings are intended to better explain the principles and practical applications of this invention, thereby enabling those skilled in the art to better understand and utilize it. However, this invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of this invention. Therefore, this invention is limited only by the claims and their full scope and equivalents, and not by the specific embodiments disclosed.
