[0031] Typical embodiments embodying the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various variations in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations herein are for illustrative purposes only and not intended to limit the present invention.

[0032] Materials need to be packaged into individual packages for sale. Each material package contains a specific number of accessories, which are packaged manually. In the current technology, staff need to check the number of accessories one by one to ensure the accuracy of the material package. However, in the process of a large number of repetitive manual operations, there are occasional material packages that are missing accessories without the staff's knowledge.

[0033] See Figures 1 to 4 The present invention provides a weighing device for conveying material packages. The weighing device includes a support frame 1, a conveying component 2, and a weighing component 3.

[0034] The conveying assembly 2 is mounted on the bracket 1; the conveying assembly 2 is provided with a rotatable conveyor line 21, which is used to carry and convey the material package to facilitate the collection of the material package.

[0035] The weighing component 3 is embedded in the conveying component 2 and is located in the middle of the conveying component 2. The weighing component 3 is connected to the conveying component 2 and contacts the conveying line 21 to measure the weight of the material package on the conveying line 21 and adjust the conveying direction of the conveying line 21. When the weight of the material package weighed by the weighing component 3 is consistent with the target weight, the conveying line 21 conveys the material in one direction. When the weight of the material package weighed by the weighing component 3 is inconsistent with the target weight, the conveying line 21 conveys the material in another direction. This facilitates the weight classification of each material package, making it easier for staff to detect material packages missing parts and reducing manual weighing and counting by staff.

[0036] The conveying assembly 2 includes a plurality of support members 22 and a drive assembly 23 for driving the conveying line 21; the plurality of support members 22 are disposed below the conveying line 21 and support the conveying line 21; the drive assembly 23 is disposed on one side of the support members 22.

[0037] The weighing assembly 3 includes multiple single-point sensors 31 for measuring weight. These sensors are connected to the support member 22 and support the conveyor line 21. Each single-point sensor 31 abuts against the support member 22 supporting the conveyor line 21 and fits flatly against it. Each single-point sensor 31 extends along the length of the conveyor line 21 and is arranged symmetrically on both sides of the center line of the conveyor line 21. The multiple single-point sensors 31 detect the weight of the material package on the conveyor line 21 based on the support member 22. Furthermore, the structural arrangement reduces the impact of the support member 22 and the conveyor line 21 on the single-point sensors 31, improving the measurement accuracy of the material package by the single-point sensors 31.

[0038] The drive assembly 23 further includes a mounting base 231, a conveyor motor 232, a transmission component 233, a drive shaft, and a driven shaft. The conveyor motor 232 is connected to the transmission component 233 and drives the drive shaft to rotate via the transmission component 233. The conveyor line 21 is respectively sleeved on the drive shaft and the driven shaft. The transmission component 233 can be a synchronous belt drive.

[0039] The conveying motor 232 is mounted on the mounting base 231 and is arranged at intervals along the length of the conveying line 21 with each of the single-point sensors 31, and is independent of each of the single-point sensors 31; the support member 22 connecting the single-point sensor 31 is relatively independent from the mounting base 231 and is located in a different area, reducing the mutual transmission between the support member 22 and the mounting base 231, reducing the vibration influence of the drive assembly 23, and ensuring the measurement accuracy of the single-point sensor 31 on the material package.

[0040] Multiple support members 22 are arranged to form a rectangular structure, which has a through hole. The rectangular structure is located below the middle of the conveyor line 21 and flatly supports the mounting base 231. The single-point sensor 31 is located on the side of the rectangular structure facing away from the conveyor line 21 and supports the width side of the rectangular structure, facing the through hole. This ensures the uniformity of support provided by the multiple support members 22, enabling measurement under stable center of gravity. Furthermore, combined with stress structure analysis, it effectively reduces the vibration impact of the conveyor line 21 on the support members 22 and improves the measurement accuracy of the single-point sensor 31 on the material package.

[0041] The drive assembly 23 further includes a connecting shaft 234, which is disposed between the conveyor motor 232 and the mounting base 231 and connects the conveyor motor 232 and the mounting base 231, so that the conveyor motor 232 and the mounting base 231 are spaced apart and suspended in the air, thereby reducing the vibration impact of the conveyor motor 232 during operation and effectively dispersing the working stress of the conveyor motor 232 in the air.

[0042] The weighing device also includes a display 4, which is mounted on one side of the bracket 1 and exposed on the bracket 1; the display 4 is electrically connected to the single-point sensor 31 and displays the weight value measured by the single-point sensor 31 for human viewing.

[0043] The bracket 1 is provided with two output ports arranged opposite each other, which are located on both sides of the conveyor line 21 and arranged along the conveying direction of the conveyor line 21. The bracket 1 is also provided with a feeding port, which is used to connect to other equipment and is located between the two output ports, directly above the middle of the conveyor line 21 and above the multiple single-point sensors 31, so as to facilitate connection to other equipment and realize timely and high-precision weighing of the material packages output by other equipment.

[0044] The conveying assembly 2 also includes an inclined plate 24, which is connected to the mounting base 231 and supports the conveying line 21 and the output port. The conveying assembly 2 also includes two baffles 25, which are located on both sides of the conveying line 21 and are movably mounted on the mounting base 231, so that the two baffles 25 can move synchronously relative to the conveying line 21 to guide the material package.

[0045] According to one aspect of the present invention, a weighing method for a weighing device is provided for conveying a material package, comprising:

[0046] The weighing method includes:

[0047] The incoming material package enters from other equipment and is positioned above the middle section of the conveyor line 21;

[0048] Weighing: Weighing component 3 contacts the conveyor line 21 and measures the weight of the material package;

[0049] When the weight of the material package measured by the weighing component 3 is consistent with the target weight, the conveyor line 21 conveys the material in one direction; when the weight of the material package measured by the weighing component 3 is inconsistent with the target weight, the conveyor line 21 conveys the material in another direction.

[0050] Although the invention has been described with reference to several typical embodiments, it should be understood that the terminology used is illustrative and exemplary, and not restrictive. Since the invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
