Description

[0002] In the production of fireworks and other products requiring accurate weighing of chemicals into powder cartridges, the weighing and filling of the powder cartridges is a crucial step, directly affecting the fireworks' ignition effect and safety. Traditional fireworks powder cartridge production relies primarily on manual operation. Firework chemicals are flammable and explosive, and manual operation is prone to accidents due to negligence. Manual weighing and filling makes it difficult to ensure consistent amounts of chemicals in each cartridge, leading to inconsistent ignition effects. Furthermore, manual operation is slow and cannot meet the demands of large-scale production. Prolonged, repetitive operations also negatively impact workers' health.

[0003] Some automated drug weighing and filling equipment has appeared on the market, but these devices still have shortcomings in structural design and functional implementation, such as low weighing accuracy, low switching efficiency, and inability to adapt to multiple drugs. Moreover, existing equipment determines the amount of material to be added by fixing the feeding and release rate. If the material falls during feeding or the release valve becomes insensitive due to the drug, it is easy to add too much or too little, which will affect the production quality.

Detailed Implementation

[0029] To make the objectives, features, and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0030] The inventors discovered through analysis of existing technologies that when weighing medicines, manual weighing and filling make it difficult to ensure that the amount of medicine in each medicine column is consistent, resulting in unstable combustion effects and low efficiency. Existing equipment determines the amount of medicine to be added by fixing the amount of medicine to be added. If the medicine falls off during the addition process or the release valve becomes insensitive due to the medicine, it is easy to add too much or too little medicine, which affects the production quality.

[0031] In the embodiments of this application, addressing the shortcomings of low efficiency and difficulty in consistently accurate filling of pharmaceutical cartridges in existing technologies, this application proposes an automatic weighing and filling device, including a feeding component, a weighing component, a switching component, a feeding assembly, and an infeed / outfeed component. The feeding component includes a three-axis moving mechanism and a clamping mechanism, with the clamping mechanism disposed at the bottom of the three-axis moving mechanism. The switching component has a turntable with at least two material troughs arranged around it. The feeding assembly has a feeding port corresponding to the weighing component. During weighing and filling, the turntable rotates, placing one material trough on the weighing component and aligning it with the feeding port, while simultaneously aligning the other material trough with the three-axis moving mechanism. By setting up the weighing component and the switching component, the feeding progress is determined based on the mass each time material is added, ensuring feeding accuracy and improving production quality.

[0032] Reference Figure 1-3 An automatic weighing and filling device is shown, including a feeding component 101, a weighing component, a switching component 102, a feeding component 103, and an infeed / outfeed component 104;

[0033] The feeding assembly 101 includes a three-axis moving mechanism and a clamping mechanism, the clamping mechanism being disposed on the three-axis moving mechanism, and the feeding / discharging assembly 104 being disposed at the bottom of the three-axis moving mechanism; the switching assembly 102 is provided with a turntable 201, the turntable 201 including at least two material troughs 202, the material troughs 202 being arranged around the turntable 201; the feeding assembly 103 is provided with a feeding port 208, the feeding port 208 corresponding to the weighing assembly;

[0034] When the medicine is being weighed and filled, the turntable 201 rotates so that one of the material troughs 202 is placed on the weighing assembly and corresponds to the feeding port 208, while the other material trough 202 corresponds to the three-axis moving mechanism.

[0035] It should be noted that the three-axis moving mechanism provides precise movement in the X, Y, and Z directions to achieve spatial positioning; the weighing component is used to accurately weigh the weight changes of the product to be processed; the switching component 102 realizes multi-station switching; the turntable 201 has a ring structure or a rectangular structure, with at least two material troughs 202 distributed circumferentially, generally two; the material troughs 202 are used to place containers to be filled, and rotate with the turntable to different stations; the feeding and discharging component 104 is used to store containers to be filled and provide them to the feeding component 101, and at the same time, transport out the filled products.

[0036] When the device is running:

[0037] The turntable 201 rotates to move a material trough (station 1) above the weighing assembly and align it with the feeding port.

[0038] In the feeding operation, the feeding component 103 adds medicine to the container at station 1 through the feeding port 208, and the weighing component monitors the weight in real time.

[0039] Simultaneous feeding occurs, and at the same time, the other material trough 202 (station 2) of the turntable 201 rotates to a position below the three-axis moving mechanism.

[0040] When changing containers, the feeding component 101 grabs an empty container from the infeed / outfeed component 104 and places it into the material trough 202 at station 2.

[0041] In a cyclical switching process, the turntable 201 continues to rotate. After the filling is completed at station 1, it rotates out, and station 2 moves to the weighing position. The above process is repeated to achieve weighing and loading of the medicine.

[0042] The automatic weighing and filling device proposed in this application is suitable for quantitative filling of various types of fireworks powder columns, and can be extended to the automatic weighing and filling of granular materials in industries such as chemical and food.

[0043] In any embodiment of this application, when the device is used for movement, such as sliding rails, clamping, rotating material trays, etc., it can be controlled by a motor to perform simple linear or rotary movements, or the rotary movement can be converted into linear movement by a lead screw.

[0044] The following will further describe an automatic weighing and filling device in this exemplary embodiment.

[0045] In one embodiment of this application, the switching component 102 includes a rotary motor 206, a lifting motor 205, and a turntable 201;

[0046] The lifting motor 205 is connected to the rotary motor 206. The turntable 201 is disposed on the lifting motor 205. The material trough 202 is disposed at the end of the turntable 201. The material trough 202 is provided with a limiting plate 203 and a receiving plate 204. The receiving plate 204 is disposed at the bottom of the limiting plate 203.

[0047] When the material trough 202 is placed on the weighing component, the weighing component passes through the receiving plate 204 and lifts the product to be filled.

[0048] It should be noted that the rotary motor 206 drives the turntable 201 to rotate around its central axis, realizing the switching of the workstation of the material trough 202 (e.g., from the feeding position → weighing position → discharging position). The rotary motor 206 is driven to rotate by a high-precision reducer to ensure that the material trough 202 is accurately aligned with each workstation. The lifting motor 205 controls the vertical lifting of the turntable 201, so that the turntable 201 docks with the weighing component. The lifting motor 205 can be servo controlled to ensure accuracy.

[0049] The limiting plate 203 is located above the material trough 202 to laterally position the container (pharmaceutical cartridge shell) and prevent it from shifting; the receiving plate 204 is located at the bottom of the limiting plate 203 and has a through hole to allow the weighing component to pass through and lift the container.

[0050] When the material trough 202 rotates to the position above the weighing component, the lifting motor 205 moves the material trough 202 down, so that the weighing tray 207 passes through the through hole of the receiving plate 204 and directly lifts the container for weighing, thus avoiding the influence of the turntable 201 structure on the weighing accuracy.

[0051] In one embodiment of this application, the feeding assembly 103 includes at least two feeding mechanisms, each feeding mechanism including a feeding funnel, an oscillating motor, and a discharge device;

[0052] The feeding funnel is located at the top of the discharge device, the discharge port 209 of the discharge device corresponds to the feeding port 208, and the oscillating motor is located in the discharge device.

[0053] In one embodiment of this application, the discharge port 209 is disposed on the side of the discharger.

[0054] It should be noted that the feeding assembly consists of at least two independent feeding mechanisms. Each feeding mechanism includes components such as a feeding funnel, an oscillating motor, and a discharge device. These components work together to achieve the storage, delivery, and precise dispensing of the drug.

[0055] The feeding funnel, located at the top of the discharge device, is an inverted cone shape with a cone angle typically between 60° and 90°. It stores the fireworks materials to be added (such as black powder, bright beads, etc.). Its inner wall is polished (roughness Ra≤0.8μm) and coated with an anti-stick coating (such as polytetrafluoroethylene) to reduce material residue and prevent blockages or dosage errors caused by material accumulation.

[0056] The discharge device, as the core component for drug delivery, has an internal spiral conveying shaft or metering chamber. The discharge port 209 on the side corresponds to the feeding port 208 (coaxiality error ≤ 0.5mm), ensuring that the drug falls into the container below for filling. The channel diameter of the discharge device can be adjusted according to the size of the drug particles (usually 3-10mm) to accommodate different specifications of fireworks agents.

[0057] The oscillating motor is fixedly installed on the outer wall of the discharge device. It outputs high-frequency micro-vibrations (vibration frequency 50-200Hz, amplitude 0.1-0.5mm) to promote uniform flow of the drug within the discharge device, releasing it to the discharge port 209. The drug is added using a side-opening, simultaneous oscillation method, rather than a bottom-opening method, to prevent over-addition. Alternatively, a similar method could be used... Figure 3 The structure shown is a vibratory feeder 301 used for feeding materials.

[0058] In one embodiment of this application, the weighing component includes a weighing tray 207 and an electronic balance, wherein the weighing tray 207 is connected to the electronic balance and corresponds to the turntable 201.

[0059] It should be noted that the weighing tray 207 and the electronic balance are fixedly connected by a rigid connector to form an integrated weighing unit. The weighing tray 207 directly supports the fireworks materials and containers to be weighed, while the electronic balance is responsible for converting the weight signal into an electrical signal to achieve accurate measurement.

[0060] When the feeding component 103 adds the drug to the container, the electronic balance monitors the total weight (including the container and the drug) on ​​the weighing tray 207 in real time and transmits the data synchronously to the control system. When the weight change reaches a preset value, the control system immediately instructs the feeding component to stop feeding, ensuring that the single-dose drug dosage error is ≤ ±0.2g, meeting the consistency requirements of the fireworks display effect.

[0061] In one embodiment of this application, the three-axis moving mechanism includes an X-axis slide rail, a Y-axis slide rail, and a Z-axis slide rail;

[0062] The X-axis slide rail is connected to the Y-axis slide rail, the Z-axis slide rail is connected to the X-axis slide rail, the clamping mechanism is disposed on the Z-axis slide rail, and the X-axis slide rail, Y-axis slide rail and Z-axis slide rail are all equipped with servo motors and encoders.

[0063] It should be noted that the three-axis moving mechanism is composed of the X-axis slide rail, the Y-axis slide rail, and the Z-axis slide rail connected in sequence to form a rectangular coordinate system spatial moving frame; the Y-axis slide rail serves as the basic axis and is horizontally fixed on the equipment frame; the X-axis slide rail is connected to the Y-axis slide rail by a slider and can translate along the Y-axis direction; the Z-axis slide rail is connected to the X-axis slide rail by a slider and can translate along the X-axis direction; the clamping mechanism is installed on the slider of the Z-axis slide rail and moves vertically along the Z-axis slide rail.

[0064] The three components work together to move the clamping mechanism to any position in three-dimensional space, covering key workstations such as the material inlet / outlet components and the material trough of the switching components.

[0065] Servo motor: A high-precision permanent magnet synchronous servo motor (power usually 100-400W) is adopted. The slide rail slider is driven by a ball screw or synchronous belt. It has high response speed (acceleration time ≤0.1 seconds) and stable output torque, ensuring that the gripping mechanism can still move smoothly under load (such as gripping a 500g medicine column container).

[0066] Encoder: Coaxially connected to the servo motor (resolution ≥1000 lines), it collects the motor rotation angle in real time and feeds it back to the control system to form a position closed-loop control, so that the repeatability of each axis can reach ±0.02mm, which meets the precise gripping requirements of fireworks containers (diameter usually 5-50mm).

[0067] In one embodiment of this application, the feeding and discharging assembly 104 includes a feeding slide rail and a hopper, the hopper being disposed on the feeding slide rail and including at least two feeding slots.

[0068] It should be noted that the feeding / discharging assembly 104 consists of two parts: the feeding slide rail and the hopper. The hopper is mounted on the feeding slide rail via a slider and can move horizontally along the slide rail to achieve precise docking with the loading assembly 101. The hopper has at least two independent feeding slots for storing empty containers to be filled or finished containers that have been filled.

[0069] In one embodiment of this application, the surface of the turntable 201 is provided with a corrosion-resistant film.

[0070] It should be noted that the corrosion-resistant film is a fluoroplastic film (such as polytetrafluoroethylene, PTFE). Fluoroplastic films are resistant to acids and alkalis, and organic solvents, and have an extremely low surface friction coefficient (≤0.05), making them less prone to drug adhesion. The corrosion-resistant film forms a physical barrier, preventing direct contact between the drug and the turntable 201 substrate, thus avoiding rust spots, peeling, or reduced structural strength on the turntable surface and improving the equipment's service life.

[0071] In one embodiment of this application, a dust removal component is further included; the dust removal component includes a dust suction hood, a dust suction pipe, and a vacuum cleaner, the dust suction hood is disposed around the weighing component and the feeding component, and the dust suction pipe connects the dust suction hood to the vacuum cleaner.

[0072] It should be noted that the dust hood is made of stainless steel and has a semi-enclosed structure. The opening faces the weighing component and the feeding component 103. The edge of the hood opening is 50-100mm away from dust sources, such as the feeding port and weighing tray, to ensure effective coverage of the dust diffusion range. A guide plate is provided inside the hood opening to guide airflow into a vortex, improving dust capture efficiency. The dust collection pipe is made of wear-resistant PVC pipe or metal corrugated pipe with an inner diameter of 50-100mm. The pipe route avoids moving parts of the equipment, such as the turntable 201 and the three-axis moving mechanism. A large radius of curvature is used at bends to reduce airflow resistance and dust deposition. The connection between the pipe and the dust hood / vacuum cleaner is sealed with a rubber sealing ring to ensure no negative pressure leakage. The vacuum cleaner is equipped with a high negative pressure fan (negative pressure value ≥20kPa) and a HEPA high-efficiency filter (filtration accuracy ≥0.3μm), which can filter fireworks powder dust (such as aluminum powder and sulfur powder). The vacuum cleaner has a built-in dust collection box (capacity ≥ 5L) made of anti-static material to prevent dust from rubbing against the container and generating static sparks.

[0073] Fireworks powder is a flammable and explosive substance. When the dust concentration in the air reaches a critical value, it can explode upon contact with static electricity, sparks, or friction. The dust collection system, through real-time dust extraction, can control the dust concentration to less than 1 / 10 of the safe threshold, reducing the risk of explosion at its source. Simultaneously, the anti-static dust collection box and grounded metal pipe design (grounding resistance ≤4Ω) prevents static electricity buildup from generating sparks.

[0074] In one embodiment of this application, a control system and a human-computer interaction interface are also included;

[0075] The control system includes a PLC controller and an industrial computer. The PLC controller is electrically connected to the actuators of the feeding component 101, the weighing component, the switching component 102, the feeding component 103, and the infeed / outfeed component 104. The industrial computer communicates with the PLC controller via an industrial Ethernet network.

[0076] It should be noted that the control system achieves precise scheduling of multi-station parallel operation through a preset process algorithm; when the turntable 201 of the switching component 102 rotates, the PLC synchronously calculates the material picking path of the three-axis moving mechanism to ensure that the feeding component 101 completes the preparation of grabbing the empty container before the turntable 201 stops; the feeding component 103 is driven by the weighing compensation algorithm of the industrial computer, combined with the real-time control of the PLC, so that the single dose error is controlled within ±0.1g.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the embodiments of the present application.

[0078] Finally, it should be noted that in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or terminal device that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or terminal device.
