Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical filling technology, and in particular to a high-speed filling machine. Background Technology

[0002] In the production processes of industries such as food and pharmaceuticals, filling machines are essential production equipment used to accurately fill liquids, powders, and other materials into containers. To ensure product quality and meet regulatory requirements, the filling process typically requires weighing and checking the containers before and after filling to guarantee the accuracy of the filling volume.

[0003] Currently, existing vial powder filling machines use a weighing method where the weighing device is directly installed in the main conveyor line when weighing vials before and after filling. The workflow for this method is as follows: when weighing is required, the main conveyor line must be completely stopped. Then, the weighing head protection device is disengaged to a designated position, and the weighing data is read after it stabilizes. After reading, the weighing head protection device returns to its original position, and finally, the main conveyor line restarts to perform the next station's filling and weighing operation.

[0004] This traditional weighing method has significant technical drawbacks. Frequent stops and starts of the main conveyor line not only prolong the weighing time, but the entire weighing process involves multiple cumbersome steps, including stopping the machine, disengaging the protective device, waiting for data stabilization, data reading, repositioning the protective device, and restarting. Each step consumes time. These numerous weighing steps severely impact the overall operating speed of the filling machine, resulting in low production efficiency.

[0005] With the rapid growth of market demand and the increasing demands of customers for production efficiency, the efficiency bottleneck of traditional weighing methods has become increasingly prominent. Frequent production line downtime not only reduces the effective utilization rate of equipment but also increases production costs, making it difficult to meet the needs of modern large-scale production. Especially in high-speed filling applications, the time loss problem of traditional weighing methods is even more pronounced, severely restricting the improvement of filling machine capacity.

[0006] Furthermore, frequent starts and stops of the main conveyor line can cause additional mechanical shocks and wear to the conveying system, affecting the stability and service life of the equipment. At the same time, vibrations and shocks during shutdowns can also adversely affect weighing accuracy, further reducing product quality consistency.

[0007] To address the aforementioned issues, existing technologies urgently need improvement. Utility Model Content

[0008] The purpose of this invention is to provide a high-speed filling machine that solves the technical problem that existing filling machines require the main conveyor line to be shut down for a long time for weighing, which affects the filling speed.

[0009] To solve the above-mentioned technical problems, this utility model provides a high-speed filling machine, comprising:

[0010] The main conveyor line is used to transport products to be weighed.

[0011] At least two weighing stations are respectively set on both sides of the main conveyor line;

[0012] At least two transfer devices are respectively installed at the weighing station;

[0013] When the transfer device moves the product to be weighed from one side of the main conveyor line to the corresponding weighing station, the transfer device simultaneously sends the weighed product back to the other side. The position where the weighed product is sent back is the empty space on the main conveyor line created by the transfer of the product to be weighed.

[0014] Optionally, the transfer device includes a drive device, a timing belt, and a push-pull device adjusting rod, wherein the drive device is connected to the push-pull device adjusting rod via the timing belt.

[0015] Optionally, the push-pull device adjusting rod includes a first end and a second end. The first end is connected to the synchronous belt, and the second end is provided with a product gripping device or a product clamping device. The product gripping device is used to independently grip the product to be weighed or release the product that has been weighed. The product clamping device is used to cooperate with the product gripping device to grip the product to be weighed or release the product that has been weighed.

[0016] Optionally, the bottom of both the product gripping device and the product clamping device is located on the same horizontal plane as the bottom of the product to be weighed.

[0017] Optionally, the product gripping device includes: a through channel along the conveying direction of the main conveyor line; two baffles arranged along the pushing and pulling direction of the adjusting rod of the push-pull device; and a connecting plate connecting the two baffles.

[0018] Optionally, the baffle has a notch, the size of which prevents the product to be weighed from passing through.

[0019] Optionally, the high-speed filling machine includes two of the aforementioned conveying devices, and the second end of the adjusting rod of the push-pull device of each of the two conveying devices includes the product gripping device.

[0020] Optionally, the high-speed filling machine includes three sets of the transfer devices, wherein the second end of the push-pull device adjusting rod of one set of the transfer devices is provided with the product gripping device; the second end of the push-pull device adjusting rod of the other two sets of transfer devices is respectively provided with the product clamping device.

[0021] The product gripping device is located between the two sets of product clamping devices. The two sets of product clamping devices cooperate with the two baffles of the product gripping device to jointly clamp the product.

[0022] Optionally, the product gripping device includes a flat plate structure that clamps and constrains the product through a gap formed with the baffle of the product gripping device.

[0023] Optionally, each of the weighing stations is equipped with a weighing device.

[0024] Through the above technical solution, this utility model has the following beneficial effects:

[0025] This invention shortens the overall process time by setting at least two weighing stations on both sides of the main conveyor line, enabling short-term shutdowns of the main conveyor line and simultaneous operation of the weighing stations on both sides. The transfer devices corresponding to the weighing stations on both sides can simultaneously perform the actions of picking up, weighing, and returning the weighed products, improving conveying efficiency. This solves the problems of excessively long weighing waiting times and low filling efficiency in existing filling machines.

[0026] Furthermore, the transfer device enables precise control: a servo motor, driven by a synchronous belt, achieves high-precision reciprocating motion of the push-pull device's adjusting rod, ensuring accurate product placement. The push-pull device's adjusting rod baffle has a notch, and its bottom is flush with the bottom of the product, reducing the weight of the adjusting rod and extending its lifespan. The flush bottom design minimizes impact on the product, making it suitable for scenarios prone to shaking, such as powder filling, and ensuring weighing accuracy. The baffle notch size restricts product passage, and the baffle and channel work together to secure the product, preventing displacement or falling during transfer. Attached Figure Description

[0038] The present invention will be described in more detail below by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0039] Please refer to Figures 1-2 This embodiment provides a high-speed filling machine, including: a main conveyor line, at least two weighing stations 5, and at least two transfer devices 2; the main conveyor line is used to convey products 4 to be weighed; the at least two weighing stations 5 are respectively arranged on both sides of the main conveyor line; the at least two transfer devices 2 are respectively arranged at the weighing stations 5; wherein, when the transfer device 2 on the first side transfers the product 4 to be weighed from the main conveyor line to the corresponding weighing station 5, the transfer device 2 on the second side simultaneously returns the weighed product, and the position where the weighed product is returned is the empty space on the main conveyor line created by the transfer of the product 4 to be weighed.

[0040] This system, where weighing stations 5 and transfer devices 2 are arranged on both sides of the main conveyor line of a high-speed filling machine, forms a parallel processing system. When one transfer device 2 moves the product 4 to be weighed from the main conveyor line to the corresponding weighing station 5, the other transfer device 2 simultaneously returns the weighed product. Product grabbing and returning occur almost simultaneously. Similarly, when one side's product is weighed, the transfer device 2 returns it, and the other transfer device 2 grabs the product 4 to be weighed and places it on the corresponding weighing station 5 for weighing. One working interval completes the grabbing on one side and the returning on the other. This working method reduces downtime and alleviates the standby losses of traditional weighing stations 5, doubling the weighing efficiency through alternating operations of the left and right stations. Simultaneously, the precise positioning control of the transfer device 2 ensures accurate product transfer, and with the help of gap filling, it avoids subsequent station jams caused by missing products on the main conveyor line, while also reducing equipment energy consumption.

[0041] In a specific example, please refer to [link / reference]. Figure 1 The high-speed filling machine includes a filling machine platform 1, which provides a stable support platform for the entire equipment. The filling machine platform 1 is made of high-quality steel with an anti-corrosion treatment, possessing good load-bearing capacity and durability. A main conveyor line is installed on the filling machine platform 1 and is used to transport the products 4 to be weighed. The main conveyor line operates continuously, ensuring the continuity and efficiency of the production line. In this embodiment, in conjunction with the aforementioned weighing method, only a brief pause is required. The conveying speed of the main conveyor line can be adjusted according to production needs.

[0042] The transfer device 2 is respectively installed at the weighing station 5 to realize the transfer of the product 4 to be weighed between the main conveyor line and the weighing station 5.

[0043] Furthermore, the transfer device 2 includes a drive unit, a timing belt 6, and a push-pull device adjusting rod 8. The drive unit is connected to the push-pull device adjusting rod 8 via the timing belt 6. The transfer device 2, combined with the timing belt 6, not only drives the push-pull device adjusting rod 8 to achieve high-precision reciprocating motion, but also ensures accurate product transfer positioning.

[0044] Furthermore, the driving device is a servo motor 7. In a specific example, the servo motor 7 can provide precise position and speed control, with a positioning accuracy of ±0.1mm, ensuring the accuracy and stability of the product transfer process. The synchronous belt 6 is made of high-strength polyurethane material, which has good wear resistance and transmission accuracy.

[0045] In another specific example, the transfer device 2 is also equipped with a position sensor and a pressure sensor for real-time monitoring of the product's position and clamping force. The position sensor is either photoelectric or magnetic induction type, with an accuracy of 0.01 mm. The pressure sensor ensures a moderate clamping force, providing stable clamping without damaging the product.

[0046] Furthermore, the push-pull device adjusting rod 8 includes a first end and a second end. The first end is connected to the synchronous belt 6, and the second end is provided with a product gripping device 81 or a product clamping device 82. The product gripping device 81 is used to independently grip the product 4 to be weighed or release the product that has been weighed. The product clamping device 82 is used to cooperate with the product gripping device 81 to grip the product 4 to be weighed or release the product that has been weighed.

[0047] In one specific example, the push-pull device adjusting rod 8 can be designed with different specifications to accommodate different bottle shapes and heights, enabling quick switching to meet the weighing requirements of different products. Adjusting rods of different specifications are replaced via a quick-clamping mechanism. This modular design improves the equipment's versatility and production efficiency, making it particularly suitable for multi-variety, small-batch production models.

[0048] It should be noted that the material of the push-pull device adjusting rod 8 needs to be suitable for filling environments with high hygiene requirements, such as food or pharmaceuticals.

[0049] For details, please refer to Figure 3 - Figure 7 The product gripping device 81 includes: a through channel along the conveying direction of the main conveyor line, two baffles arranged along the pushing and pulling direction of the push-pull device adjusting rod 8, and a connecting plate connecting the two baffles.

[0050] The through channel along the main conveyor line is designed to allow products to move smoothly along the predetermined conveying direction, enabling continuous conveying on the assembly line. Baffles positioned along the push-pull direction of the adjusting rod 8 of the push-pull device guide the products, keeping them in the correct position during transport, preventing deviation, and ensuring accurate arrival at the grabbing position of the push-pull device, thus improving grabbing accuracy. The baffles also act as barriers, preventing products from falling off the conveyor line due to vibration, collision, or other reasons during transport, protecting product integrity, and reducing production interruptions and quality issues caused by product drops. Connecting plates linking two baffles enhance the structural stability of the baffles, allowing them to better perform their positioning and protection functions for the products.

[0051] In this embodiment, when the product 4 to be weighed enters the through channel of the main conveyor line, the baffle and connecting plate on one side clamp the product 4 to be weighed and transfer it from the main conveyor line to the corresponding weighing station 5. At the same time, the transfer device 2 on the other side sends the weighed product back. The position where the weighed product is sent back is the empty space on the main conveyor line created by the transfer of the product 4 to be weighed.

[0052] Furthermore, the baffle has a notch. The size of the notch prevents the product 4 to be weighed from passing through, thus ensuring that the product does not detach from the product gripping device 81 during pushing and pulling. The notch is designed to reduce the weight of the device while extending its service life.

[0053] In this embodiment, the design of the notch takes into account both the need for stable clamping of the product and the need for weight reduction.

[0054] In a specific example, to reduce the weight of the push-pull device adjusting rod 8 and prevent deformation over prolonged use, a bridge-shaped notch is designed at the bottom of the adjusting rod 8. This structural design effectively reduces the weight by approximately 30% to 40% while maintaining strength, thus extending the service life of the equipment. The shape and size of the bridge-shaped notch have been optimized through finite element analysis to ensure uniform stress distribution under maximum load.

[0055] Furthermore, the bottoms of both the product gripping device 81 and the product clamping device 82 are located on the same horizontal plane as the bottom of the product 4 to be weighed, ensuring stability during product transfer and preventing the product from tipping over or being damaged.

[0056] In this embodiment, the bottom and the contact point of the bottle are on the same horizontal plane. The product will not leave the weighing station 5 during the pushing and pulling process, avoiding frequent machine stoppages for calibration due to offset. This allows the production line to operate continuously and stably, reduces manual intervention time, effectively increases output per unit time, and reduces production cycle costs.

[0057] When the high-speed filling machine includes two sets of transfer devices 2, the two transfer devices are respectively set on both sides of the main conveyor line. The second end of the push-pull device adjustment rod 8 of each transfer device 2 is equipped with a product gripping device 81. The product gripping device 81 is used to grip, transfer or release the product. The two product gripping devices 81 form a structure of "baffle-through channel-baffle, baffle-through channel-baffle".

[0058] Furthermore, the high-speed filling machine includes three sets of the aforementioned transfer devices 2. The second end of the push-pull device adjusting rod 8 of one set of the transfer devices 2 is equipped with the product gripping device 81; please refer to [further details omitted]. Figure 7 The second end of the push-pull device adjusting rod 8 of the other two sets of transfer devices 2 is respectively provided with the product gripping device 82. When the high-speed filling machine includes three sets of transfer devices, the other end of the push-pull device adjusting rod 8 of the first transfer device located in the middle is equipped with a product gripping device 81, and the transfer devices on both sides are the second transfer device and the third transfer device, respectively, and the end of their push-pull device adjusting rod 8 is equipped with a product gripping device 82.

[0059] The first transfer device, in conjunction with the second and third transfer devices on both sides, realizes the product transfer process on both sides. The product gripping device 81 and the two sets of product clamping devices 82 are arranged side by side in the vertical direction of the main conveyor line. The two sets of product clamping devices 82 cooperate with the two baffles of the product gripping device 81 to jointly clamp the product. Specifically, the other end of the push-pull device adjusting rod 8 of the first transfer device is equipped with a product gripping device 81. The product gripping device 81 includes two baffles and a connecting plate. The two baffles and the adjacent product clamping devices 82 form a through channel along the conveying direction of the main conveyor line.

[0060] Understandably, please continue to refer to this. Figure 1 The three sets of transfer devices 2 can be set on both sides of the main conveyor line. However, in the direction perpendicular to the transport direction of the main conveyor line, the product gripping device 81 of the first transfer device is located between the two product clamping devices 82. The product clamping devices 82 of the second and third transfer devices include flat plate structures. They clamp and constrain the product through the gap formed by the baffle of the product gripping device 81. They form two symmetrical through channels with the two baffles of the product gripping device 81. The through channels move back and forth between the main conveyor line and the weighing station as the push-pull device adjusting rod 8 moves, so as to clamp, transfer or release the product.

[0061] The configuration of three sets of transfer devices 2 enables a more flexible product handling method. Through the coordinated movement of the three sets of transfer devices, an effective gripping of the product is formed. The three sets of transfer devices move synchronously. The product gripping device 81 in the middle provides the main positioning and support function, while the product gripping devices 82 on both sides constrain the product from the outside of the product gripping device 81, forming a structure of "flat plate-through channel-baffle-baffle-through channel-flat plate".

[0062] By controlling the servo motor 7, the products on the main conveyor line can be clamped and pushed to the empty weighing station 5. Simultaneously, the weighed products are clamped and pushed to the main conveyor line. The transfer device 2 continues to clamp the products to be weighed 4 and the weighed products, pushes the products to be weighed to the weighing device, and sends the weighed products back to the main conveyor line. Through reciprocating motion, the weighing time is saved, thereby increasing the speed of the filling machine.

[0063] Furthermore, each of the weighing stations 5 is equipped with a weighing device.

[0064] In this embodiment, the weighing stations 5 are respectively located on both sides of the main conveyor line, and each weighing station 5 is equipped with a weighing device.

[0065] In one specific example, the weighing device is a high-precision electronic scale, which can accurately measure the weight of the product 4 to be weighed.

[0066] In another specific example, the weighing device is equipped with vibration damping measures, including vibration damping pads and vibration isolation covers, so that the weighing process is not affected by external interference. The selection and installation method of the weighing device are common practices for those skilled in the art and will not be described in detail here. The number of weighing stations 5 can be configured according to the scale of the production line. In large production lines, multiple weighing stations 5 can be set up to meet high capacity requirements.

[0067] The working principle of the high-speed filling machine provided in this embodiment is as follows: When the transfer device 2 on the first side transfers the product 4 to be weighed from the main conveyor line to the corresponding weighing station 5, the transfer device 2 on the second side simultaneously returns the weighed product. The position where the weighed product is returned is the empty space on the main conveyor line created by the transfer of the product 4 to be weighed. This alternating working method on both sides allows the main conveyor line to run continuously, avoiding the problem of frequent shutdowns waiting for the weighing data to stabilize in traditional solutions, and greatly improving production efficiency.

[0068] In summary, this high-speed filling machine consists of a main conveyor line, at least two weighing stations, and at least two transfer devices. By placing the weighing stations on both sides of the main conveyor line and employing an alternating transfer method, the weighing process and the main conveyor line operation are synchronized, improving production efficiency. The transfer devices utilize servo motors paired with synchronous belt drives to push-pull adjustment rods. One end is connected to the synchronous belt, and the other end has a product gripping device for gripping and releasing products. The main conveyor line has a through channel, and the product position is fixed by a notched baffle and connecting plate. Each weighing station is equipped with a weighing device. During operation, the two transfer devices work together: one side transfers products from the main conveyor line for weighing, while the other side returns the weighed products to an empty space on the main conveyor line. The three sets of transfer devices operate in relay, with the weighing stations on both sides working synchronously. This achieves precise and efficient transfer, stable product positioning, and effectively solves the problems of long weighing wait times and low filling efficiency in traditional filling machines.

[0069] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
