Abstract

This invention discloses a split-type high-volume, series-connected dynamic dual-weighing system and weighing method, comprising weighing platform A and weighing platform B. Weighing platforms A and B are arranged in series along the conveyor line, with the outlet end of weighing platform A connected to the inlet end of weighing platform B. Weighing platform A has inlet photoelectric sensors on both sides of the inlet end, intermediate photoelectric sensors on both sides of the middle, and outlet photoelectric sensors on both sides of the outlet end. Weighing platform B has inlet photoelectric sensors on both sides of the inlet end and outlet photoelectric sensors on both sides of the outlet end. The conveyor platform of weighing platform A is shorter than that of weighing platform B, and the distance between the inlet and outlet photoelectric sensors of weighing platform B is greater than the distance between the inlet and intermediate photoelectric sensors of weighing platform A. The inlet and intermediate photoelectric sensors of weighing platform A classify packages by length and select the weighing platform. Weighing platforms A and B are independently calibrated and weigh independently (weighing platform A weighs short packages, weighing platform B weighs long packages), which improves resolution, weighing accuracy, and efficiency compared to combined weighing of weighing platforms A and B.

Description

Technical Field

[0001] This invention belongs to the field of logistics automation equipment and relates to a split-type high-throughput series dynamic dual scale and a weighing method. Background Technology

[0002] High throughput efficiency is the development trend of dynamic DWS systems. The weighing efficiency of dynamic scales has always been a key factor in improving the performance of DWS systems, in order to meet the express delivery sorting industry's continuous pursuit of cost reduction and sorting efficiency improvement. To adapt to application scenarios with randomly varying package lengths, dual-platform dynamic scales have a greater advantage in efficiency than single-platform dynamic scales. Currently, the dual-platform weighing mode of A-scale weighing and A+B-scale weighing is commonly used. All packages are divided into two categories based on a certain size: short packages and long packages. Scale A completes the weighing of short packages, while scale A+B completes the weighing of long packages. In this type of dual-platform dynamic scale, both scales work together to weigh long packages, and the package weight is the sum of the weights on scale A and scale B. The overall length of the scale body is relatively small, which can save some installation space. However, there are three problems: First, it is impossible to directly calibrate the combined weighing platform consisting of platform A and platform B, resulting in a decrease in weighing accuracy in the A+B weighing mode; second, the range of the combined weighing platform is twice that of a single platform weighing platform, increasing the scale division value and reducing the resolution, which is equivalent to using a large-capacity scale to weigh a small-weight package, leading to a decrease in weighing precision; third, when the package length is measured by multiplying the time when a single photoelectric sensor is blocked by the speed of the conveyor belt, the measurement error is large, and some short packages are misjudged as long packages, resulting in a loss of circulation efficiency. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a split-type high-volume series dynamic dual scale and weighing method, which adopts weighing mode of scale platform A and scale platform B to realize calibration and package length judgment, improve resolution and weighing accuracy.

[0004] To achieve the above objectives, the present invention employs the following technical solution:

[0005] A split-type high-volume serial dynamic dual scale, comprising weighing platform A and weighing platform B;

[0006] Weighing platform A and weighing platform B are arranged in series along the conveyor line, with the outlet end of weighing platform A connected to the inlet end of weighing platform B.

[0007] Weighing platform A has A-scale entry photoelectric sensors on both sides of the entry end, A-scale middle photoelectric sensors on both sides of the middle, and A-scale exit photoelectric sensors on both sides of the exit end; Weighing platform B has B-scale entry photoelectric sensors on both sides of the entry end and B-scale exit photoelectric sensors on both sides of the exit end.

[0008] The length of the conveyor platform of scale A is less than that of scale B, and the distance between the inlet photoelectric sensor and the outlet photoelectric sensor of scale B is greater than the distance between the inlet photoelectric sensor and the middle photoelectric sensor of scale A.

[0009] Preferably, scale platform A includes scale conveyor platform A and scale mounting base A, with scale conveyor platform A located on top of scale mounting base A, and scale platform B includes scale conveyor platform B and scale mounting base B, with scale conveyor platform B located on top of scale mounting base B.

[0010] Furthermore, both the mounting base of scale A and the mounting base of scale B are equipped with at least four adjustable shoe angles at the bottom.

[0011] Furthermore, both the A-scale conveyor platform and the B-scale conveyor platform include a conveyor belt, a pad, a drive roller assembly, and a driven roller assembly. The drive roller assembly and the driven roller assembly are rotatably connected to both ends of the pad, and the drive roller assembly and the driven roller assembly are connected by the conveyor belt.

[0012] Furthermore, both the mounting base of scale A and the mounting base of scale B are equipped with motor reducer assemblies, which are connected to the drive roller assembly via a synchronous belt.

[0013] Furthermore, photoelectric mounting aluminum profiles are installed on both sides of the top of the pad.

[0014] Furthermore, both the A-scale conveyor platform and the B-scale conveyor platform are equipped with weighing sensors at their bottoms.

[0015] Furthermore, there are four weighing sensors, located at the four corners of the bottom of the conveyor platforms of scale A and scale B.

[0016] Furthermore, both the mounting base of scale A and the mounting base of scale B are equipped with junction boxes, which are connected to the load cells.

[0017] A weighing method for a split-type high-volume, series-connected dynamic dual-weighing system includes the following steps:

[0018] The package first enters platform A. After the head of the package triggers the photoelectric sensor on platform A, it continues to move forward. If the head of the package triggers the photoelectric sensor on platform A at the same time as the head triggers the photoelectric sensor on the middle of platform A, then the package is a long package, and platform A activates the straight-through mode. The package then enters platform B to complete the weighing. If the tail of the package triggers the photoelectric sensor on platform A, but the head of the package does not trigger the photoelectric sensor on the middle of platform A, then the package is a short package, platform A activates the weighing function to complete the weighing, and platform B activates the straight-through mode.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] This invention optimizes the weighing mode by employing a weighing mode using platform A and platform B, eliminating the need for a combined A+B weighing system. It also optimizes the dual-scale structure, with platforms A and B arranged in series along the conveyor line. Platforms A and B can be calibrated independently, ensuring weighing accuracy. Platforms A and B have the same weighing range, and their mounting bases and weighing instruments are structurally independent, preventing interference and avoiding the increased scale division and reduced resolution associated with combined weighing. Both platforms A and B are equipped with inlet and outlet photoelectric sensors. Platform A also has a central photoelectric sensor, with the distance between the central and inlet photoelectric sensors serving as the dividing line between long and short packages. Package length determination is no longer affected by platform speed fluctuations during package entry, improving the accuracy of package length assessment. Attached Figure Description

[0032] like Figure 1 As shown, this is a split-type high-volume series dynamic dual scale according to the present invention. This device mainly consists of scale platform A and scale platform B.

[0033] Scale platform A includes scale conveyor 19 and scale mounting base 2, with scale conveyor 19 located on top of scale mounting base 2. Scale platform B includes scale conveyor 22 and scale mounting base 17, with scale conveyor 22 located on top of scale mounting base 17.

[0034] The A-scale mounting base 2 and the B-scale mounting base 17 form the base of the entire dynamic scale, used to fix the entire dynamic scale and ensure the stability of the equipment. Both the A-scale mounting base 2 and the B-scale mounting base 17 have at least four adjusting feet at their bottom, located at the four corners, used to adjust the height of the A-scale conveyor platform 19 and the B-scale conveyor platform 22, as well as to adjust their levelness to adapt to different ground flatness conditions.

[0035] The A-scale conveyor platform 19 includes an A-scale conveyor belt 5, an A-scale platform pad 6, photoelectric mounting aluminum profiles 11, a drive roller assembly 14, and a driven roller assembly 3. The drive roller assembly 14 and the driven roller assembly 3 are respectively connected to both ends of the A-scale platform pad 6 by bearings. The drive roller assembly 14 and the driven roller assembly 3 are connected by the A-scale conveyor belt 5 to ensure synchronous movement of the A-scale conveyor belt 5 during operation. The A-scale conveyor belt 5 is arranged around the A-scale platform pad 6. There are two photoelectric mounting aluminum profiles 11, located on the upper sides of the A-scale platform pad 6, respectively, for mounting multiple sets of photoelectric sensors.

[0036] Multiple weighing sensors 20 are provided on the top of the A-scale mounting base 2. In this embodiment, four weighing sensors 20 are provided on the A-scale mounting base 2, located at the four corners of the top of the A-scale mounting base 2. The fixed end of the weighing sensor 20 is installed on the top of the A-scale mounting base 2. The loading end of the weighing sensor 20 is connected to the four corners of the A-scale platform pad 6 of the A-scale conveyor 19 through the Z-shaped connecting block 10. The Z-shaped connecting block 10 is used to fix the loading end of the weighing sensor 20 and connect the weighing sensor 20 to the A-scale platform pad 6 to ensure that the weighing sensor 20 can accurately detect the weight of the goods on the A-scale conveyor belt 5.

[0037] The mounting base 2 of scale A is equipped with a motor reducer assembly 21. The motor reducer assembly 21 is connected to the drive roller assembly 14 via a synchronous belt 16. The motor reducer assembly 21 serves as the power source to drive the drive roller assembly 14, thereby realizing the continuous transmission of the conveyor belt 5 of scale A.

[0038] A junction box 18 is provided on the mounting base 2 of scale A. The junction box 18 connects the load cell 20, the motor reducer assembly 21 and the photoelectric sensor. It is used to summarize the electrical connections of various components of scale A for centralized management and to connect the signals of the load cell 20, the motor reducer assembly 21 and the photoelectric sensor.

[0039] In this embodiment, there are three sets of photoelectric sensors on the A-scale conveyor platform 19. The first set is located on both sides of the inlet end of the A-scale conveyor platform 19, serving as the A-scale inlet photoelectric sensor 4. The second set is located on both sides of the middle of the A-scale conveyor platform 19, which can be close to the inlet end or the outlet end, serving as the A-scale middle photoelectric sensor 7. The third set is located on both sides of the outlet end of the A-scale conveyor platform 19, serving as the A-scale outlet photoelectric sensor 8. The A-scale inlet photoelectric sensor 4 and the A-scale outlet photoelectric sensor 8 are used to detect the moment when the package enters and leaves the A-scale conveyor platform 19, respectively. The A-scale middle photoelectric sensor 7, in conjunction with the A-scale inlet photoelectric sensor 4, is used to determine whether the package is a long package.

[0040] The B-scale conveyor platform 22 includes a B-scale conveyor belt 15, a B-scale platform pad 12, photoelectric mounting aluminum profiles 11, a drive roller assembly 14, and a driven roller assembly 3. The drive roller assembly 14 and the driven roller assembly 3 are respectively connected to the B-scale platform pad 12 at both ends via bearings. The drive roller assembly 14 and the driven roller assembly 3 are connected by the B-scale conveyor belt 15 to ensure synchronous movement of the B-scale conveyor belt 15 during operation. The B-scale conveyor belt 15 is arranged around the B-scale platform pad 12. There are two photoelectric mounting aluminum profiles 11, located on both sides above the B-scale platform pad 12, for mounting multiple sets of photoelectric sensors.

[0041] Multiple weighing sensors 20 are provided on the top of the B-scale mounting base 17. In this embodiment, four weighing sensors 20 are provided on the B-scale mounting base 17, located at the four corners of the top of the B-scale mounting base 17. The fixed end of the weighing sensor 20 is installed on the top of the B-scale mounting base 17. The loading end of the weighing sensor 20 is connected to the four corners of the B-scale platform pad 12 of the B-scale conveyor 22 through the Z-shaped connecting block 10. The Z-shaped connecting block 10 is used to fix the loading end of the weighing sensor 20 and connect the weighing sensor 20 to the B-scale platform pad 12 to ensure that the weighing sensor 20 can accurately detect the weight of the goods on the B-scale conveyor belt 15.

[0042] The B scale mounting base 17 is equipped with a motor reducer assembly 21. The motor reducer assembly 21 is connected to the drive roller assembly 14 via a synchronous belt 16. The motor reducer assembly 21 serves as the power source to drive the drive roller assembly 14, thereby realizing the continuous transmission of the B scale conveyor belt 15.

[0043] A junction box 18 is provided on the mounting base 17 of scale B. The junction box 18 connects the load cell 20, the motor reducer assembly 21 and the photoelectric sensor. It is used to summarize the electrical connections of various components of scale B for centralized management and to connect the signals of the load cell 20, the motor reducer assembly 21 and the photoelectric sensor.

[0044] In this embodiment, there are two sets of photoelectric sensors on the B scale conveyor 22. One set is located on both sides of the B scale conveyor 22 at the weighing end, serving as the B scale inlet photoelectric sensor 9. The other set is located on both sides of the B scale conveyor 22 at the weighing end, serving as the B scale outlet photoelectric sensor 13. The B scale inlet photoelectric sensor 9 and the B scale outlet photoelectric sensor 13 are used to detect the time when the package enters and leaves the B scale conveyor 22, respectively.

[0045] In this embodiment, the length of conveyor platform 19 of scale A is less than that of conveyor platform 22 of scale B, but the width is the same. The distance between the inlet photoelectric sensor 9 and the outlet photoelectric sensor 13 of scale B is greater than the distance between the inlet photoelectric sensor 4 and the middle photoelectric sensor 7 of scale A, so that the short package is weighed on scale A and the long package is weighed on scale B.

[0046] In this embodiment, the junction box 18 is used to compensate for the output error of each weighing sensor 20 and the error caused by the different deformation of the four corners of the weighing platform. By adjusting the potentiometer corresponding to each weighing sensor 20 in the junction box 18, the output of each weighing sensor 20 is made as consistent as possible, thereby further improving the weighing accuracy.

[0047] In this embodiment, weighing platform A and weighing platform B are connected end to end and arranged in series along the conveyor line. The exit end of weighing platform A 19 is connected to the inlet end of weighing platform B 22. After the package passes through weighing platform A 19, it can directly enter weighing platform B 22.

[0048] Since the output end of conveyor platform 19 of scale A is connected to the input end of conveyor platform 22 of scale B, the output photoelectric sensor 8 of scale A and the input photoelectric sensor 9 of scale B can use the same photoelectric sensor.

[0049] like Figure 5 As shown, the weighing principle of the dynamic dual scale in this embodiment is as follows: The package first enters the dynamic dual scale through the A scale platform. The weight of the package is transmitted to the weighing sensor 20 through the Z-shaped connector 10 and its accessories on the scale platform, causing the weighing sensor 20 to deform and output a weight signal. When the package enters the A scale conveyor platform 19, if the head of the package triggers the A scale entry photoelectric sensor 4 on the A scale conveyor platform 19, the receiver of the A scale entry photoelectric sensor 4 is blocked. If the receiver of the A scale entry photoelectric sensor 4 remains blocked, and the head of the package triggers the A scale middle photoelectric sensor 7 on the A scale conveyor platform 19, then the package is a long package, and the A scale conveyor platform 19 starts the straight-through mode, and the package enters the B scale platform to complete the weighing. If the tail of the package triggers the A scale entry photoelectric sensor 4 on the A scale conveyor platform 19, but the head of the package has not yet triggered the A scale middle photoelectric sensor 7, then the package is a short package, the A scale platform starts the weighing function to complete the weighing, and the B scale platform starts the straight-through mode, thereby realizing independent weighing of the A and B scale platforms.

[0050] This invention has two main advantages. First, it optimizes the weighing mode by using both A-platform and B-platform weighing, eliminating the need for a combined A+B platform. Second, it optimizes the dual-scale structure by connecting two separate single-scale platforms in series to form a dual-scale system. An additional photoelectric sensor 7 is added to the A-scale platform, which, in combination with the A-scale input photoelectric sensor 4, is used to classify packages by length, improving the accuracy of package length determination.

[0051] Weighing platform A is a short platform single scale for weighing short packages, while weighing platform B is a long platform single scale for weighing long packages. Weighing platforms A and B are arranged in series along the conveyor line. Weighing platforms A and B can be calibrated independently to ensure weighing accuracy.

[0052] Weighing platform A and weighing platform B have the same weighing range. The mounting base structures of weighing platform A and weighing platform B are independent, and the weighing instruments are independent in function, so they do not affect each other. This avoids the problem of increased weighing division value and reduced resolution when weighing platforms A and B are combined.

[0053] Both weighing platforms A and B are equipped with inlet and outlet photoelectric sensors. Weighing platform A also has an intermediate photoelectric sensor 7. The distance between the intermediate photoelectric sensor 7 and the inlet photoelectric sensor 4 on weighing platform A is the dividing length between long and short packages; the determination of package length is no longer affected by the speed fluctuation of the weighing platform during the package entry process.

[0054] 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.
