Abstract
Description
Technical Field
[0001] This utility model relates to the field of batching and weighing technology, and in particular to a weighing mechanism and batching and weighing equipment. Background Technology
[0002] Currently, some materials need to be filled into receiving containers during production, and after filling, the receiving containers need to be weighed to detect the weight of the materials in the receiving containers, so as to achieve accurate filling and batching of materials.
[0003] In existing technologies, the receiving container is mostly moved in the XY direction for transport during the weighing process (i.e., linear movement is used to transport the receiving container to achieve weighing and other processes). This structural form is inconvenient for upstream and downstream processes of the entire production line and is not conducive to the layout of upstream and downstream equipment. In addition, in existing technologies, other structures can easily interfere with the weighing of the receiving container when it is being weighed, affecting the accuracy of the weighing. Utility Model Content
[0004] To address the aforementioned technical problems, this utility model provides a weighing mechanism that uses a rotating disk to drive a receiving container. The circular rotation of the disk moves the receiving container, facilitating the arrangement and connection of upstream and downstream equipment in the production line. Furthermore, the diameter of the through hole on the rotating disk is larger than that of the receiving container. Therefore, after the rotating disk has moved the receiving container to its designated position, it can be retracted a certain distance, separating the rotating disk from the receiving container. This prevents the rotating disk from interfering with the weighing of subsequent receiving containers, thereby improving weighing accuracy.
[0005] A weighing mechanism includes a support tray, a weighing module, a rotating disk, and a rotation drive module.

[0008] A through hole is provided on the rotating disk corresponding to the weighing pan. The through hole extends through the rotating disk along the height direction and is used to accommodate a receiving container. The diameter of the through hole is larger than that of the receiving container.

[0014] Preferably, the support tray is provided with a clearance hole, which extends through the support tray along the height direction, and the weighing pan of each weighing module is located at one of the clearance holes.
[0015] Preferably, the top surface of the support tray is horizontal, and the top surface of the weighing pan is flush with the top surface of the support tray.
[0016] Preferably, the rotary drive module includes a stepper motor and a transmission unit, the output shaft of the stepper motor is connected to the transmission unit, and the transmission unit is connected to the rotating disk.

[0041] This utility model provides a weighing mechanism, which includes a support tray, a weighing module, a rotating disk, and a rotation drive module. The weighing pan of the weighing module is located in the support tray, and multiple weighing modules are arranged in sequence along the circumference of the support tray. The rotating disk is rotatably arranged and located above the support tray to drive the receiving container on the support tray to move. A through hole is opened on the rotating disk corresponding to the weighing pan. The through hole extends through the rotating disk along the height direction to accommodate the receiving container, and the diameter of the through hole is larger than that of the receiving container. Multiple through holes are arranged in sequence along the circumference of the rotating disk and correspond to the weighing modules. The rotation drive module is connected to the rotating disk to drive the rotating disk to rotate. The weighing mechanism is equipped with multiple weighing modules, allowing for simultaneous weighing of multiple receiving containers, thus improving weighing efficiency. Furthermore, the mechanism utilizes the circular rotation of the rotating disk to move the receiving containers, resulting in a more compact overall structure and facilitating the arrangement and integration of upstream and downstream equipment along the production line. Additionally, the diameter of the through-hole on the rotating disk is larger than that of the receiving container. This allows the rotating disk to retract after moving the receiving container into position, separating the hole wall from the container. During weighing, the rotating disk does not contact the receiving container, preventing interference with the weighing process and improving weighing accuracy.
[0042] Please refer to the following: Figures 1 to 8 In one embodiment, a weighing mechanism 100 is provided for weighing the receiving container 200 after filling.
[0043] The weighing mechanism 100 includes a support tray 10, a weighing module 20, a rotating disk 30, and a rotation drive module 40. The support tray 10 is mainly used to support the receiving container 200, the weighing module 20 is mainly used to weigh the receiving container 200, the rotating disk 30 is mainly used to move the receiving container 200, and the rotation drive module 40 is mainly used to drive the rotating disk 30 to rotate.
[0044] The weighing pan 21 of the weighing module 20 is located in the support tray 10, and multiple weighing modules 20 are provided, which are distributed sequentially along the circumference of the support tray 10. Because multiple weighing modules 20 are provided and distributed sequentially along the circumference, multiple receiving containers 200 can be weighed simultaneously through multiple weighing modules 20, thereby improving weighing efficiency.
[0045] The rotating disk 30 is rotatably mounted and positioned above the support tray 10 to move the receiving container 200 on the support tray 10. A through hole 31 is provided on the rotating disk 30 corresponding to the weighing pan 21, extending through the rotating disk 30 along its height and accommodating the receiving container 200. In other words, the receiving container 200 is accommodated in the rotating disk 30 through the through hole 31. When the rotating disk 30 rotates, it contacts the receiving container 200 through the wall of the through hole 31, thereby moving the receiving container 200. The diameter of the through hole 31 is larger than that of the receiving container 200. Because the diameter of the through hole 31 is larger than that of the receiving container 200, after the rotating disk 30 moves the receiving container 200 into position, the rotating disk 30 can retract a certain distance, causing the receiving container 200 to be spaced apart from the wall of the through hole 31, preventing the receiving container 200 from contacting the rotating disk 30, thereby improving weighing accuracy. Here, "the diameter of the through hole 31 is larger than that of the receiving container 200" means that the diameter of the through hole 31 is larger than the portion of the receiving container 200 located within the through hole 31. For example, as... Figure 5 As shown, the receiving container 200 is divided into a top 210, a middle 220, and a bottom 230 from top to bottom. When the receiving container 200 is fed into the weighing mechanism 100, the middle 220 is located in the through hole 31, and the diameter of the through hole 31 is larger than the diameter of the middle 220. Alternatively, in some embodiments, to facilitate the placement of the receiving container 200 into the weighing mechanism 100, the diameter of the bottom 230 may be smaller than the through hole 31. This allows the receiving container 200 to be directly inserted into the rotating disk 30 from above and placed on the support tray 10 when placed into the weighing mechanism 100.
[0046] Multiple through holes 31 are provided, and the multiple through holes 31 are distributed sequentially along the circumference of the rotating disk 30 and correspond to the weighing modules 20. That is to say, the distribution position of the multiple through holes 31 corresponds to the distribution position of the multiple weighing modules 20, so that during weighing, multiple receiving containers 200 can be placed into the weighing mechanism 100, and the rotating disk 30 can drive the multiple receiving containers 200 to move synchronously, and the synchronous weighing measurement of multiple receiving containers 200 can be performed at one time.
[0047] The rotary drive module 40 is connected to the rotating disk 30 and is used to drive the rotating disk 30 to rotate.
[0048] Understandably, most existing technologies use linear movement to transfer receiving containers. To improve weighing efficiency, multiple receiving containers need to be weighed simultaneously, requiring multiple weighing modules in the weighing mechanism. However, because existing technologies use linear movement, the more weighing modules that can be accommodated in the weighing mechanism, the longer the entire production line becomes, hindering subsequent processes after weighing and negatively impacting the layout of upstream and downstream equipment. This limitation restricts the number of weighing modules that can be placed in existing weighing mechanisms, thus limiting the improvement in weighing efficiency.
[0049] In this embodiment, the weighing mechanism 100 uses the circular rotation of the rotating disk 30 to move the receiving container 200, causing it to move in an arc-like motion for transport. This allows for a more compact overall structure, facilitating the arrangement and connection of upstream and downstream equipment. It also allows for a greater number of weighing modules 20, further improving weighing efficiency. Furthermore, the diameter of the through hole 31 is larger than that of the receiving container 200. Therefore, once the rotating disk 30 has moved the receiving container 200 to its designated position, the rotating disk 30 can retract and separate from the receiving container 200, preventing it from interfering with the weighing process and improving weighing accuracy.
[0050] In one embodiment, the weighing mechanism 100 operates as follows: the receiving container 200 is passed through the through hole 31 and placed on the support tray 10 (the receiving container 200 can be placed by a robotic arm). Then, the rotary drive module 40 drives the rotating disk 30 to rotate. The rotation of the rotating disk 30 causes the inner wall of the through hole 31 to contact the outer wall of the receiving container 200, thereby moving the receiving container 200. When the receiving container 200 is moved to the center of the weighing pan 21, the rotary drive module 40 drives the rotating disk 30 to rotate in the opposite direction by a certain angle, thereby separating the inner wall of the through hole 31 from the outer wall of the receiving container 200, thus improving the accuracy of weighing.
[0051] In one embodiment, the weighing module 20 is an industrial-grade electronic scale, and the weighing module 20 has an accuracy of ±0.00001g and a weighing accuracy of ±0.00005g.
[0052] Preferably, in one embodiment, the center of the rotating disk 30 and the center of the supporting tray 10 are located on the same straight line, and the distances of each through hole 31 on the rotating disk 30 from the center of the rotating disk 30 are equal, and the distances of each weighing pan 21 in the supporting tray 10 from the center of the supporting tray 10 are equal. Thus, after the rotating disk 30 rotates one revolution, one through hole 31 can sequentially flow through each weighing pan 21. That is, when a receiving container 200 rotates one revolution driven by the rotating disk 30, the receiving container 200 can sequentially flow through each weighing pan 21, thereby facilitating operations such as dispensing and filling.
[0053] Preferably, in one embodiment, along the circumference of the rotating disk 30, the through hole 31 includes a first hole 311 at one end and a second hole 312 at the other end. The first hole 311 and the second hole 312 are interconnected, and the diameter of the first hole 311 matches the receiving container 200, while the diameter of the second hole 312 is larger than that of the receiving container 200. Wherein, the diameter of the first hole 311 matches the receiving container 200, meaning that the diameter of the first hole 311 matches the portion of the receiving container 200 located within the through hole 31. For example, the diameter of the first hole 311 can be equal to the diameter of the central portion 220, so that when the receiving container 200 is located within the first hole 311, the wall of the first hole 311 can fit against one side of the central portion 220. In other words, in this embodiment, the through hole 31 extends circumferentially for a certain length, and the through hole 31 has a structure that is larger at one end and smaller at the other. This structure facilitates the movement of the receiving container 200 driven by the rotating disk 30, and also facilitates the separation of the rotating disk 30 from the receiving container 200 during weighing. It is understood that when the rotating disk 30 needs to move the receiving container 200, the wall of the first hole 311 adheres to one side of the receiving container 200, thereby moving the receiving container 200 through the wall of the first hole 311. Since the diameter of the first hole 311 matches that of the receiving container 200, the wall of the first hole 311 can fit more perfectly with one side of the receiving container 200. During movement, the receiving container 200 will not experience radial displacement, ensuring that the receiving container 200 moves to the center of the weighing pan 21, thereby improving the accuracy of subsequent weighing. Once in position, the rotating disk 30 rotates in the opposite direction by a certain angle, so that the receiving container 200 is located in the second hole 312 or in the area between the second hole 312 and the first hole 311, thereby separating the wall of the through hole 31 from the receiving container 200.
[0054] More preferably, in one embodiment, the diameter of the through hole 31 gradually increases from the first hole 311 to the second hole 312. That is, in this embodiment, the diameter of the through hole 31 gradually changes along the circumferential direction, which facilitates the placement of the receiving container 200 and facilitates the contact and separation between the rotating disk 30 and the receiving container 200.
[0055] Preferably, in one embodiment, the through holes 31 on the rotating disk 30 are evenly spaced and distributed sequentially, covering the entire rotating disk 30 circumferentially, and the number of through holes 31 is greater than the number of weighing modules 20. This structure facilitates the loading and unloading of materials into the receiving container 200. For example, in one embodiment, the rotating disk 30 has 16 through holes 31, while the weighing modules 20 have 15. That is, there is an area in the entire circumference where no weighing modules 20 are arranged, and this area can be used as a loading and unloading station. When the through holes 31 flow to this area, the receiving container 200 can be loaded and unloaded accordingly by a robotic arm.
[0056] Preferably, in one embodiment, the top surface 11 of the support tray 10 is provided with a step 12. The step 12 is located in front of the weighing pan 21 of the weighing module 20, where "front" is defined with reference to the direction in which the receiving container 200 moves on the support tray 10. That is, when the rotating disk 30 moves the receiving container 200, the receiving container 200 will first flow through the step 12 and then through the weighing pan 21 corresponding to the step 12. Along the circumference of the rotating disk 30, the height of the step 12 gradually changes, and the height of the side of the step 12 closer to the weighing pan 21 is higher than the height of the side farther from the weighing pan 21. In other words, as the receiving container 200 flows over the step 12, the height of the receiving container 200 is gradually increased before it falls onto the weighing pan 21. In this embodiment, the step 12 provides better protection for the weighing pan 21. It is understandable that industrial-grade electronic scales, due to their high precision, are more sensitive to impacts. If an installation error occurs during the installation of the weighing module 20, causing the weighing pan 21 to protrude beyond the top surface 11, the receiving container 200 may easily collide with the weighing pan 21 when moving on the support tray 10. The step 12, by providing this step, can raise the receiving container 200 to a certain height when it is about to contact the weighing pan 21, thus preventing it from impacting the weighing pan 21 of the weighing module 20.
[0057] More preferably, in one embodiment, a step 12 is provided on the front side of the weighing pan 21 of each weighing module 20.
[0058] More preferably, in one embodiment, the height of the side of the step 12 away from the weighing pan 21 is flush with the top surface 11, thereby allowing the receiving container 200 to move more smoothly onto the step 12.
[0059] Preferably, in one embodiment, the support tray 10 is provided with a clearance hole 13, which penetrates the support tray 10 along the height direction, and the weighing pan 21 of each weighing module 20 is located at one clearance hole 13. That is, in this embodiment, the support tray 10 is provided with multiple hole structures, and the weighing pan 21 is correspondingly disposed in these hole structures.
[0060] More preferably, in one embodiment, the top surface 11 of the support tray 10 is horizontally positioned, and the top surface of the weighing pan 21 is flush with the top surface 11 of the support tray 10. This structure ensures horizontal weighing and improves weighing accuracy.
[0061] Preferably, in one embodiment, the rotating disk 30 is parallel to the support tray 10, and the rotating disk 30 is parallel to each of the weighing pans 21.
[0062] Specifically, in one embodiment, the weighing module 20 is installed at the bottom of the support tray 10.
[0063] Preferably, in one embodiment, the rotary drive module 40 includes a stepper motor and a transmission unit. The output shaft of the stepper motor is connected to the transmission unit, and the transmission unit is connected to the rotating disk 30. Specifically, in one embodiment, the transmission unit may employ a belt drive structure, using a pulley to drive the rotating disk 30 to rotate. The stepper motor can perform high-precision circular rotational motion, while different speed ratios can be achieved through gears, belts, and other components to reach the required speed.
[0064] Meanwhile, in one embodiment, a batching and weighing device 1000 is also provided, which includes a hopper 300 and the weighing mechanism 100. The hopper 300 is located above the rotating disk 30, and the discharge port of the hopper 300 is provided corresponding to the through hole 31. That is, when the rotating disk 30 moves the receiving container 200, the receiving container 200 can be moved below the discharge port of the hopper 300, so that material can be poured into the receiving container 200 through the hopper 300.
[0065] The silo 300 is a container for storing powders and liquids before weighing, and the receiving container 200 is a container for holding materials during the mixing and batching process of powders, liquids, and powders and liquids.
[0066] Preferably, in one embodiment, the batching and weighing device 1000 further includes a hopper mounting plate 400, on which multiple hoppers 300 are disposed, and the multiple hoppers 300 are sequentially distributed along the circumference of the hopper mounting plate 400. More preferably, each hopper 300 corresponds to a weighing module 20. Among the multiple hoppers 300, there are powder hoppers 310 and liquid hoppers 320. The powder hopper 310 is mainly used to store powder materials, while the liquid hopper 320 is mainly used to store liquid materials.
[0067] Preferably, in one embodiment, the discharge port of the hopper 300 is located above the weighing pan 21. More preferably, in one embodiment, the discharge port of the hopper 300 is located directly above the center of the weighing pan 21, thereby better ensuring the accuracy of weighing.
[0068] Understandably, some existing weighing equipment uses circular motion for weighing. However, in existing technology, multiple hoppers can only be matched with one weighing module. During operation, the hoppers move while the weighing module remains stationary, which is relatively slow and cannot meet the needs of high-efficiency production.
[0069] In this embodiment, the batching and weighing device 1000 moves the receiving container 200 via the rotating disk 30, while the weighing module 20 and the hopper 300 remain stationary. Furthermore, the device is equipped with multiple weighing modules 20 and multiple hoppers 300, thereby further improving the efficiency of batching and weighing.
[0070] Preferably, in one embodiment, the batching and weighing equipment 1000 has an inlet / outlet station 1001 and multiple batching and weighing stations 1002. The inlet / outlet station 1001 and the multiple batching and weighing stations 1002 are evenly spaced along the circumference. Each batching and weighing station 1002 is correspondingly provided with a hopper 300 and a weighing module 20. When the batching and weighing equipment 1000 is running, an empty receiving container 200 is inserted into the through hole 31 from the inlet / outlet station 1001 by a robotic arm and placed on the support tray 10. Then, the receiving container 200 is moved to the batching and weighing station 1002 by the rotation of the rotating disk 30. The rotating disk 30 then rotates back a certain angle, and then the hopper 300 discharges the material, and the weighing module 20 weighs it. When the rotating disk 30 drives the receiving container 200 back to the infeed / outfeed station 1001, the receiving container 200, after being batched, is removed by a robotic arm. The materials in each of the hoppers 300 can be different. During the batching and weighing process, the system can dispense materials according to demand. For example, if the receiving container 200 needs to be filled with materials from batching and weighing stations 1002 1 and 4, then the receiving container 200 will only dispense materials from the corresponding hoppers 300 when it moves to those stations. When it moves to other batching and weighing stations 1002, the other hoppers 300 will not dispense materials. This structure allows for the configuration of different materials according to demand, greatly improving the efficiency of batching and weighing.
[0071] For example, in one embodiment, the batching and weighing equipment 1000 has 16 stations, which are evenly spaced along the circumference, of which 15 stations are batching and weighing stations 1002 and 1 station is a material feeding and discharging station 1001.
[0072] Understandably, to improve weighing accuracy, the receiving container must be precisely moved to the center of the weighing module during weighing to avoid interfering with the weighing process (the receiving container can only contact the weighing pan during weighing). Furthermore, high-precision weighing requires a high degree of levelness and stability from the weighing module; it must be kept level and free from external forces.
[0073] The batching and weighing equipment 1000 can simultaneously distribute 15 weighing modules 20 on a 360° circular disk. The weighing modules 20 are fixed to ensure horizontality during weighing and are not affected by external forces. The receiving container 200, driven by a stepper motor, moves in a circular motion on the 360° disk, accurately moving to the center of the weighing module 20 and then retracting. This ensures that the receiving container 20 does not contact its surroundings during weighing, improving weighing accuracy. With 15 weighing stations operating simultaneously and the 15 weighing modules 20 not interfering with each other, simultaneous batching at multiple stations is possible. Furthermore, the weighing process relies on the weight feedback from the high-precision weighing modules, which are monitored in real-time and the weight is increased sequentially to achieve the required accuracy.
[0074] The batching and weighing device 1000 can be applied to all powder batching, liquid batching, and powder and liquid mixed batching. The material stored in the silo 300 can be selected according to different batching requirements.
