Description

Technical Field

[0001] The invention belongs to the field of logistics automation equipment and relates to a split high-throughput cargo serially connected dynamic double scale and a weighing method. Background Art

[0002] High currency efficiency is the development trend of the dynamic DWS system. The weighing efficiency of the dynamic scale has always been a key factor in improving the performance of the DWS system. In order to meet the pursuit of the express sorting industry to continuously reduce costs and improve sorting efficiency. In order to adapt to the application scenarios where the length of the package changes randomly, the double-table dynamic scale has more advantages in efficiency than the single-table dynamic scale. At present, the double-table weighing mode of A scale weighing and A+B scale weighing is mostly adopted. All parcels are divided into two categories of short parcels and long parcels according to a certain size. The A scale completes the weighing of short parcels, and the A+B scale completes the weighing of long parcels; this double-table dynamic scale uses two scales to weigh long parcels in coordination, and the weight of the parcel is the sum of the weights of the A scale and the B scale; the total length of the scale body is small, which can save some installation space. However, there are three problems. First, it is impossible to directly calibrate the combined weighing platform composed of weighing platform A and weighing 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-table weighing platform. The graduation value of the combined weighing platform increases and the resolution decreases, which is equivalent to using a large-scale scale to weigh a small package, resulting in reduced weighing precision. Third, when the package length is measured by multiplying the time 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 currency efficiency. Summary of the invention

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

[0004] In order to achieve the above object, the present invention adopts the following technical solutions: A split type high throughput tandem dynamic double scale, comprising a scale platform A and a scale platform B; Scales A and B are arranged in series along the conveyor line, with the outgoing end of scale A butted against the incoming end of scale B.

[0012] Furthermore, a junction box is provided on both the A scale mounting base and the B scale mounting base, and the junction box is connected to the weighing sensor.

[0013] A weighing method for a split type high throughput tandem dynamic double scale includes the following processes: The package first enters scale A, and the head of the package triggers the A scale entry photoelectric sensor and continues to move forward. If the package triggers the A scale entry photoelectric sensor and the head also triggers the A scale middle photoelectric sensor, the package is a long package, and scale A starts the direct-through mode. The package enters scale B to complete weighing. If the tail of the package triggers the A scale entry photoelectric sensor and the head of the package does not trigger the A scale middle photoelectric sensor, the package is a short package, and scale A starts the weighing function to complete weighing, and scale B starts the direct-through mode.

[0022] like Figure 1 As shown, a split type high throughput tandem dynamic double scale according to the present invention is shown, and the device is mainly composed of a scale platform A and a scale platform B.

[0023] The A scale platform includes an A scale conveying platform 19 and an A scale mounting base 2, wherein the A scale conveying platform 19 is located on the top of the A scale mounting base 2, and the B scale platform includes a B scale conveying platform 22 and a B scale mounting base 17, wherein the B scale conveying platform 22 is located on the top of the B scale mounting base 17.

[0024] The A scale mounting base 2 and the B scale mounting base 17 are the bases of the entire dynamic scale, which are used to fix the entire dynamic scale to ensure the stability of the equipment. The A scale mounting base 2 and the B scale mounting base 17 are both provided with at least four adjustment shoe angles at the bottom, located at the four corners of the A scale mounting base 2 and the B scale mounting base 17, which are used to adjust the height of the A scale conveying platform 19 and the B scale conveying platform 22, and to adjust the levelness of the A scale conveying platform 19 and the B scale conveying platform 22 to adapt to different ground flatness conditions.

[0025] The A scale conveyor platform 19 includes an A scale conveyor belt 5, an A scale platform pad 6, an optoelectronic mounting aluminum profile 11, an active roller assembly 14 and a driven roller assembly 3. The active roller assembly 14 and the driven roller assembly 3 are respectively connected to the two ends of the A scale platform pad 6 through bearings. The active roller assembly 14 and the driven roller assembly 3 are connected through the A scale conveyor belt 5 belt to ensure the 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 optoelectronic mounting aluminum profiles 11, which are respectively located above the two sides of the A scale platform pad 6 and are used to install multiple groups of photoelectric sensors.

[0026] A plurality of weighing sensors 20 are arranged on the top of the A scale mounting base 2. In the present embodiment, four weighing sensors 20 are arranged on the A scale mounting base 2, which are respectively 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 conveying platform 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.

[0027] A motor reducer assembly 21 is provided on the A scale mounting base 2, and the motor reducer assembly 21 is connected to the active roller assembly 14 through a synchronous belt 16. The motor reducer assembly 21 is used as a power source to drive the active roller assembly 14 to realize continuous transmission of the A scale conveyor belt 5.

[0028] A junction box 18 is provided on the mounting base 2 of scale A, and the junction box 18 is connected to the weighing sensor 20, the motor reducer assembly 21 and the photoelectric sensor, and is used to summarize the electrical connections of the various components of the scale platform A for centralized management, and to connect the signals of the weighing sensor 20, the motor reducer assembly 21 and the photoelectric sensor.

[0029] In this embodiment, there are three groups of photoelectric sensors on the A scale conveyor platform 19. The first group is located on both sides of the weighing end of the A scale conveyor platform 19, serving as the A scale weighing photoelectric sensor 4. The second group is located on both sides of the middle of the A scale conveyor platform 19, which can be close to the weighing end or the weighing end, serving as the A scale middle photoelectric sensor 7. The third group is located on both sides of the weighing end of the A scale conveyor platform 19, serving as the A scale weighing photoelectric sensor 8. The A scale weighing photoelectric sensor 4 and the A scale weighing photoelectric sensor 8 are respectively used to detect the moment when the package enters and leaves the A scale conveyor platform 19. The A scale middle photoelectric sensor 7 cooperates with the A scale weighing photoelectric sensor 4 to determine whether the package is a long package.

[0030] The B scale conveyor platform 22 includes a B scale conveyor belt 15, a B scale platform pad 12, an optoelectronic mounting aluminum profile 11, an active roller assembly 14 and a driven roller assembly 3. The active roller assembly 14 and the driven roller assembly 3 are respectively connected to the B scale platform pad 12 at both ends through bearings. The active roller assembly 14 and the driven roller assembly 3 are connected through the B scale conveyor belt 15 belt to ensure the 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 optoelectronic mounting aluminum profiles 11, which are respectively located above the two sides of the B scale platform pad 12 and are used to install multiple groups of photoelectric sensors.

[0031] A plurality of weighing sensors 20 are arranged on the top of the B scale mounting base 17. In the present embodiment, four weighing sensors 20 are arranged on the B scale mounting base 17, which are respectively 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 conveying platform 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.

[0032] A motor reducer assembly 21 is provided on the B scale mounting base 17, and the motor reducer assembly 21 is connected to the active roller assembly 14 through a synchronous belt 16. The motor reducer assembly 21 is used as a power source to drive the active roller assembly 14 to achieve continuous transmission of the B scale conveyor belt 15.

[0033] A junction box 18 is provided on the B scale mounting base 17, and the junction box 18 is connected to the weighing sensor 20, the motor reducer assembly 21 and the photoelectric sensor, and is used to summarize the electrical connections of the various components of the B scale platform for centralized management, and connect the signals of the weighing sensor 20, the motor reducer assembly 21 and the photoelectric sensor.

[0034] In this embodiment, there are two groups of photoelectric sensors on the B scale conveyor platform 22, one group is located on both sides of the weighing end of the B scale conveyor platform 22, serving as the B scale weighing photoelectric sensors 9, and the other group is located on both sides of the weighing end of the B scale conveyor platform 22, serving as the B scale weighing photoelectric sensors 13. The B scale weighing photoelectric sensors 9 and the B scale weighing photoelectric sensors 13 are respectively used to detect the moment when the package enters and leaves the B scale conveyor platform 22.

[0035] In this embodiment, the length of the A scale conveyor platform 19 is smaller than that of the B scale conveyor platform 22, and they have the same width. The distance between the B scale input photoelectric device 9 and the B scale output photoelectric device 13 is larger than the distance between the A scale input photoelectric device 4 and the A scale middle photoelectric device 7, so that short packages are weighed on the A scale platform and long packages are weighed on the B scale platform.

[0036] The function of the junction box 18 in this embodiment is 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 scale platform. By adjusting the corresponding potentiometer of 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.

[0037] In this embodiment, the A scale platform and the B scale platform are connected in series end to end and arranged in series along the conveyor line direction. The outflow end of the A scale conveyor platform 19 is connected to the inflow end of the B scale conveyor platform 22. After the package passes through the A scale conveyor platform 19, it can directly enter the B scale conveyor platform 22.

[0038] Since the weighing end of the A scale conveying platform 19 is connected to the weighing end of the B scale conveying platform 22, the A scale weighing out photoelectric sensor 8 and the B scale weighing in photoelectric sensor 9 can use the same photoelectric sensor.

[0039] like Figure 5 As shown, the weighing principle of the dynamic dual scale in this embodiment is: the package first enters the dynamic dual scale through the A scale platform, and 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, so that the weighing sensor 20 is deformed and outputs 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 4 on the A scale conveyor platform 19, the receiver of the A scale entry photoelectric 4 is blocked. Thereafter, if the A scale entry photoelectric 4 receiver remains blocked, the head of the package triggers the A scale middle photoelectric 7 on the A scale conveyor platform 19 again, then the package is a long package, and the A scale conveyor platform 19 starts the direct-through mode, and the package enters the B scale to complete the weighing. If when the tail of the package triggers the A scale entry photoelectric 4 on the A scale conveyor platform 19, the head of the package has not triggered the A scale middle photoelectric 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 direct-through mode, thereby realizing independent weighing of the A and B scale platforms.

[0040] The present invention first optimizes the weighing mode, adopts the weighing mode of A scale and B scale, and does not use the weighing mode of A+B combined scale. Second, it optimizes the double scale structure, and samples two split single scales in series to form a double scale; a set of A scale intermediate photoelectric 7 is added to the A scale, which is combined with the A scale input photoelectric 4 to classify the package length, thereby improving the accuracy of package length judgment.

[0041] Scale A is a short single scale for weighing short packages, and Scale B is a long single scale for weighing long packages. Scales A and B are arranged in series along the conveyor line. Scales A and B can be calibrated separately to ensure weighing accuracy.

[0042] Scale A and Scale B have the same measuring range. The mounting bases of Scale A and Scale B are independent in structure, and the weighing instruments are independent in function and do not affect each other, thus avoiding the problem of increased weighing division value and reduced resolution due to the combination of Scale A and Scale B.

[0043] Both the A and B scales are equipped with weighing and unweighing photoelectric sensors, and the A scale intermediate photoelectric sensor 7 is also installed on the A scale. The distance between the A scale intermediate photoelectric sensor 7 and the A scale weighing photoelectric sensor 4 on the A scale is the dividing length between long packages and short packages; the package length judgment is no longer affected by the fluctuation of the scale speed during the weighing process.
