Description

Technical Field

[0001] This invention relates to the field of automated equipment for rubber product processing, specifically to an automatic weighing and transfer device and method for rubber raw materials used in mattress airbags. Background Technology

[0002] In mattress manufacturing, airbags are a key support unit, requiring high consistency in the proportion of internal rubber raw materials and high filling efficiency. If the raw materials are not weighed accurately or the conveying process is unstable, it will directly affect the rebound performance and structural stability of the finished product. Traditional methods relying on manual or semi-automatic means are no longer sufficient to meet the dual requirements of precision and rhythm in the modern mattress industry.

[0003] Currently, some equipment uses single-point weighing combined with fixed conveying devices for material distribution. The operation is relatively intuitive and the equipment structure is relatively simple. This type of equipment realizes the static weighing of rubber raw materials through a preset weighing platform. At the same time, it uses an independent conveyor motor to drive the conveyor belt to introduce the weighed raw materials into the next process. In some cases, it has a fast weighing response, is suitable for simple weighing tasks of small batches of materials, and has low system cost and is easy to maintain. It has certain practical application value in application scenarios that do not require high adaptability and high precision.

[0004] However, the overall linkage and adaptability of these existing equipment are relatively lacking. First, the weighing device is usually fixed outside the conveying structure, and the two are not synchronized, which makes it easy to distort the proportioning inspection during the process, and is not suitable for continuous and efficient production of multiple batches. Second, the height adjustment is mostly done by simple lifting frames or rigid slides, which are prone to misalignment when connecting complex process interfaces, causing material jamming or even slippage, requiring frequent manual intervention and affecting the cycle time. Furthermore, the positioning accuracy of traditional conveying components is low, relying only on limit blocks for adjustment, and lacks dynamic correction capabilities. It cannot adaptively adjust when encountering eccentric loads or path interference. Finally, the control system is mostly modular and fragmented, lacking effective information coordination and full-process automatic scheduling mechanisms. Linkage failures and delayed abnormal responses can easily cause the entire line to stop.

[0005] Therefore, this invention proposes an automatic weighing and transfer device and method for rubber raw materials used in mattress airbags to address the shortcomings of existing technologies. Summary of the Invention

[0040] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Please see the appendix Figure 1 , Attachment Figure 3 and attached Figure 4 This invention provides an automatic weighing and transmission device for rubber raw materials used in mattress airbags, including a base 1. A lifting assembly 2 is provided at the top of the base 1 for lifting the device. The lifting assembly 2 includes a base plate 201, which is fixedly connected to the top of the base 1. A cylinder 202 is fixedly connected inside the base plate 201. A connecting rod 203 is rotatably connected to the output end of the cylinder 202. A slider 204 is rotatably connected to both the front and rear ends of the connecting rod 203. The interior of the base plate 201 is slidably connected to the exterior of the slider 204. An inner rod 205 is rotatably connected to both the front and rear sides of the connecting rod 203. An outer rod 206 is rotatably connected to both the front and rear sides of the base plate 201. The exterior of the inner rod 205 is rotatably connected to the exterior of the outer rod 206. A load-bearing plate 3 is provided on the upper side of the lifting assembly 2. An upper frame 208 is fixedly connected to the bottom of the load-bearing plate 3. A slider 207 is slidably connected to both the front and rear sides of the upper frame 208. The exterior of the slider 207 is rotatably connected to the exterior of the outer rod 206.

[0042] Specifically, a lifting assembly 2 is provided at the top of the base 1. The lifting assembly 2 is used to adjust the height of the entire equipment to meet different operating requirements. The lifting assembly 2 includes a base plate 201, which is fixedly connected to the top of the base 1. A cylinder 202 is fixedly connected inside the base plate 201. A connecting rod 203 is rotatably connected to the output end of the cylinder 202. Driven by the cylinder 202, the connecting rod 203 can drive the lifting action of other components to ensure that the equipment can operate smoothly during use.

[0043] Both ends of the connecting rod 203 are rotatably connected to sliders 204. Slider 204 is slidably connected to the inside of the base plate 201, so that the movement of the connecting rod 203 can be restricted by the movement of slider 204. The design of slider 204 enables the lifting assembly 2 to remain stable and effectively reduces the impact of vibration on the equipment, thereby improving the accuracy of rubber raw material weighing. Both the front and rear sides of the connecting rod 203 are rotatably connected to inner rods 205. Inner rods 205 are rotatably connected to outer rods 206, forming a double rod structure. This structure makes the entire lifting assembly more stable during operation.

[0044] The base plate 201 is rotatably connected to the front and rear sides with outer rods 206. The outer rods 206 are rotatably connected to the inner rods 205, which enables the lifting assembly 2 to generate a large thrust in the vertical direction, ensuring that the equipment can still operate smoothly under heavy load. The bottom of the load-bearing plate 3 is fixedly connected to the upper frame 208, which is used to support the load-bearing plate 3 for stable lifting. The front and rear sides of the upper frame 208 are slidably connected to sliders 207. The sliders 207 are rotatably connected to the outer rods 206, ensuring that the upper frame 208 can move stably during lifting.

[0045] Please see the appendix Figure 1 and attached Figure 7 A movable component 4 is provided at the top of the load-bearing plate 3. The movable component 4 is used to move the equipment horizontally. The movable component 4 includes a mounting block 401, which is fixedly connected to the top of the load-bearing plate 3.

Movable seats 403 are installed on the left and right sides of the exterior of the slide rails 402. The interior of the mounting block 401 is slidably connected to the exterior of the movable seats 403. A connecting block 404 is fixedly connected to the exterior of the movable seats 403.

[0046] Specifically, the moving component 4 can drive the equipment to move horizontally, allowing the equipment to move to the next process inlet for conveying. The slide rail 402 is made of high-strength steel to improve the stability and durability of the equipment during horizontal movement and avoid wear or deformation caused by long-term use. The design of the slide rail 402 ensures that the moving seat 403 can slide smoothly and accurately in the horizontal direction, reducing the resistance caused by friction during operation. The design of the moving seat 403 takes into account the balance and movement accuracy of the equipment. It is externally fixedly connected to a connecting block 404, which serves to connect with other equipment components. During transmission, the structure of the connecting block 404 ensures that it can drive the stable movement of other equipment.

[0047] Please see the appendix Figure 1 and attached Figure 5A weighing verification component 5 is provided on the upper side of the moving component 4. The weighing verification component 5 is used to weigh and verify the rubber raw materials. The weighing verification component 5 includes a mounting frame 501. The outside of the connecting block 404 is fixedly connected to the outside of the mounting frame 501. The mounting frame 501 is slidably connected to the top of the load-bearing plate 3. Weighing sensors 502 are fixedly connected to the four corners of the top of the mounting frame 501. A horizontal plate 503 is provided on the top of the weighing sensors 502 on both the left and right sides. Support columns 504 are fixedly connected to the front and rear sides of the top of the horizontal plate 503.

[0048] Specifically, the weighing verification component 5 is used to weigh and verify the rubber raw materials to check whether the weight of the rubber raw materials conforms to the material ratio. Through the stable connection between the mounting frame 501 and the connecting block 404, the mounting frame 501 can move horizontally on the load-bearing plate 3 when the connecting block 404 moves. The arrangement of the weighing sensors 502 ensures uniform weighing of the rubber raw materials. The four corner sensors 502 can simultaneously receive the pressure changes of the material during operation, thereby ensuring the accuracy and stability of the weighing. The outside of each weighing sensor 502 is connected to the horizontal plate 503. The horizontal plate 503 effectively collects the detection data of the sensors 502, ensuring that the data from different sensors can be accurately merged and transmitted to the computer controller 7 for processing. Through the distribution of the support columns 504, the weight of the rubber raw materials on the conveyor belt 601 on the support columns 504 can be stably and evenly distributed to the weighing sensors 502 for weighing.

[0049] Please see the appendix Figure 1 and attached Figure 2 A conveying component 6 is provided on the upper side of the weighing and verification component 5. The conveying component 6 is used to convey rubber raw materials. The conveying component 6 includes a conveyor belt 601, which is fixedly connected to the top of the support column 504. A motor 602 is fixedly connected to the bottom of the conveyor belt 601. A pulley 603 is fixedly connected to the output end of the motor 602. A pulley 604 is rotatably connected to the rear side of the conveyor belt 601. The outside of the pulley 604 is fixedly connected to the rotating shaft of the conveyor belt 601. The pulley 603 and the pulley 604 are connected by a belt.

[0050] Specifically, the conveyor assembly 6 is used to transport the rubber raw materials, allowing them to enter the next process. The conveyor belt 601 is fixed to the top of the support column 504, distributing the weight of the rubber raw materials to the weighing sensor 502. The motor 602 is a high-efficiency DC motor, ensuring the conveyor belt 601 can start smoothly and maintain stable speed and power output throughout operation. Pulley 1 603 and Pulley 2 604 are connected by a belt, ensuring the drive transmission of the conveyor belt 601. The belt is selected to be wear-resistant and tensile-resistant. High-strength materials ensure smooth operation of the conveyor system even under high loads. Both pulley 603 and pulley 604 are precision-machined to ensure the meshing accuracy between them, thereby guaranteeing the smooth and continuous operation of the conveyor belt 601 during operation and preventing material transmission interruptions due to belt slack or detachment. The external part of pulley 604 is fixedly connected to the rotating shaft of the conveyor belt 601, ensuring that the motion transmission of the conveyor belt is not affected by external interference. At the same time, through precise bearing design, the rotational smoothness of pulley 604 is ensured, further improving the stability of the equipment.

[0051] Please see the appendix Figure 1 and attached Figure 6 A cable drag chain 8 is provided on the front top of the mounting block 401, and a connecting rod 801 is fixedly connected to the front top of the mounting bracket 501. The outside of the cable drag chain 8 is fixedly connected to the outside of the connecting rod 801.

[0052] Specifically, a connecting rod 801 is fixedly connected to the front top of the mounting bracket 501. The cable drag chain 8 is fixedly connected to the outside of the connecting rod 801. The cable drag chain 8 is designed with wear-resistant materials and a flexible structure to ensure smooth cable movement during equipment operation and prevent damage to the cable due to friction or traction. The fixed connection between the connecting rod 801 and the outside of the cable drag chain 8 serves to stabilize the connection between the cable drag chain 8 and other parts of the equipment. The connecting rod 801 is designed with high-strength alloy materials, which can effectively resist pressure and friction during long-term operation and ensure the stability of the cable drag chain 8.

[0053] Please see the appendix Figure 8 The computer controller 7 includes:

[0054] The weighing detection and proportioning verification module is responsible for receiving and processing real-time data from the weighing verification component 5, and automatically detecting and verifying the quality of rubber raw materials.

[0055] The lifting and positioning control module is used to control the lifting component 2 and the moving component 4 to precisely dock the conveying component 6 to the entrance of the next process after the rubber raw material quality has been tested and verified as qualified.

[0056] The conveying control module is used to start the operation of the conveying component 6 when the conveying component 6 is precisely docked at the entrance of the next process, so as to convey the rubber raw material to the next process.

[0057] The process scheduling and reset module is used to schedule the entire process after the rubber raw material is transported, perform automatic reset, and control the coordination and working sequence between various modules.

[0058] Specifically, the computer controller 7 includes a weighing detection and proportioning verification module, which is responsible for receiving and processing real-time data from the weighing verification component 5 to automatically detect and verify the quality of the rubber raw materials. This module receives data from the weighing sensor 502, first measures the quality of the rubber raw materials in real time, and then uses a proportioning verification algorithm to determine the proportions. The specific proportioning verification algorithm formula is as follows:

[0059]

[0060] Among them: Q cal Indicates the verification result; w i M represents the proportioning coefficient of the i-th raw material; i This represents the real-time weighing data of the i-th type of rubber raw material; n represents the number of types of raw materials.

[0061] If Q cal If the set tolerance range is exceeded, the system will trigger an alarm signal and stop the current conveying process.

[0062] The lifting and positioning control module is used to control the lifting component 2 and the moving component 4 to precisely align the conveying component 6 to the entrance of the next process after the rubber raw material quality has been inspected and verified. This module automatically adjusts the height of the lifting component 2 based on feedback information from the weighing and proportioning verification module to ensure the accuracy of the alignment between the conveying component 6 and the entrance of the next process. The accuracy and speed of the lifting control are adjusted using the following formula:

[0063] h(t) = h0 + Δh(t);

[0064] Where: h(t) is the real-time height of the conveying component 6; h0 is the initial height; Δh(t) is the adjustment amount after verification of the quality of the rubber raw materials.

[0065] This adjustment is calculated by the control system to ensure precise alignment and prevent subsequent material transport from being affected.

[0066] The conveying control module is used to activate the conveying component 6 when it is precisely aligned with the entrance of the next process, thus conveying the rubber raw material to the next process. Based on the alignment position of the conveying component 6 and the pass / fail status of the rubber raw material, this module controls the start of the motor 602, driving pulleys 603 and 604 to move the conveyor belt 601. The speed of the conveyor belt is adjusted using the following formula:

[0067] v(t) = v0 + k × (M) avg -M target );

[0068] Where: v(t) is the instantaneous speed of the conveyor belt; v0 is the initial speed; k is the adjustment coefficient; M avg M represents the average mass of the rubber raw materials. target For target quality.

[0069] While ensuring that the quality of rubber raw materials meets the process requirements, the speed of the conveyor belt will be stabilized at an ideal value to avoid over-transportation or stagnation of raw materials.

[0070] The process scheduling and reset module is used to schedule the entire process after the rubber raw material delivery is completed, automatically reset the process, and control the coordination and working sequence between various modules. This module is responsible for the scheduling and control of the entire production process, ensuring that each module starts and stops at the correct time, avoiding equipment failure or production delays due to uncoordinated operations. The reset process is achieved through the following formula:

[0071]

[0072] Wherein: T reset Indicates the time required for reset; T max The maximum time for the entire production cycle; t i The runtime for each module is m; m is the number of modules.

[0073] After each production cycle ends, the system automatically calculates the reset time and completes the reset of each module step by step according to the preset program sequence, in preparation for the next production cycle.

[0074] Through the coordinated operation of the above modules, the computer controller 7 ensures the efficient and accurate operation of the entire automatic weighing and transfer equipment for the rubber raw materials of the mattress airbag. At the same time, by adjusting the operating parameters of each operating module through precise algorithms, the automation level and stability of the system are greatly improved.

[0075] This invention also provides a method for automatically weighing and transferring rubber raw materials for mattress airbags, comprising the following steps:

[0076] S1. Place various rubber raw materials sequentially onto conveyor belt 601;

[0077] S2, Weighing sensor 502 weighs each raw material and the weighing detection and proportioning verification module performs proportioning verification;

[0078] S3. If the verification is successful, the lifting and positioning control module controls the lifting component 2 and the moving component 4 to raise the conveying component 6 and connect it with the next process entry.

[0079] S4. The conveying control module controls the start of the conveying component 6 to convey the rubber raw material to the next process.

[0080] S5, the process scheduling and reset module controls the equipment to reset, preparing for the next round of weighing and conveying process.

[0081] Specifically, S1, various rubber raw materials are placed sequentially on conveyor belt 601; in this step, the operator places different types of rubber raw materials sequentially at the starting position of conveyor belt 601 by manual or automatic means.

[0082] S2. Weighing sensor 502 weighs each raw material and the weighing detection and proportioning verification module performs proportioning verification. In this step, when the rubber raw material passes through the weighing verification component 5, the weighing sensor 502 measures the weight of each raw material in real time. The sensor 502 transmits pressure data through the support of the cross plate 503 and the support column 504 and sends this data to the weighing detection and proportioning verification module. The module receives the data and performs calculations to determine whether the quality of the raw material meets the set proportioning standard. If the weighing data is within the set range, the weighing detection and proportioning verification module confirms that the raw material has passed the verification; otherwise, it triggers an alarm or stops the operation.

[0083] S3. If the verification is successful, the lifting and positioning control module controls the lifting component 2 and the moving component 4 to raise the conveyor component 6 and connect it to the entrance of the next process. At this time, according to the ratio verification result instruction, the lifting and positioning control module controls the lifting component 2 to precisely adjust the height of the conveyor belt 601. By starting the cylinder 202, the connecting rod 203 and the slider 204 are moved, thereby driving the inner rod 205 and the outer rod 206 to move crosswise, which in turn drives the upper frame 208 to move upward, thereby driving the load-bearing plate 3 to move upward, so as to precisely adjust the height of the conveyor belt and connect it to the entrance of the next process. At the same time, the moving component 4 starts to operate. The moving component 4 moves on the slide rail 402 through the slide rail moving seat 403, thereby connecting the conveyor belt 601 to the position of the process entrance in the horizontal direction through the connecting block 404, ensuring that the material smoothly enters the next production stage.

[0084] S4. The conveying control module controls the start of the conveying component 6 to convey the rubber raw material to the next process. After the conveying component 6 is precisely docked at the entrance of the next process, the conveying control module starts the motor 602, drives the pulleys 603 and 604, and drives the conveyor belt 601 to run through the belt drive system. The conveyor belt 601 starts to convey the rubber raw material to the next process at a stable speed.

[0085] S5. The process scheduling and reset module controls the equipment to reset and prepare for the next round of weighing and conveying process. After completing a round of weighing and conveying, the process scheduling and reset module starts to reset the equipment. According to the running status of the entire process, the module automatically adjusts the state of the lifting component 2 and the moving component 4 to ensure that the conveyor belt 601, weighing and verification component 5 and other modules return to the initial working position and are ready to start the next round of material weighing and conveying.

[0086] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
