Abstract
Description
Technical Field
[0001] This invention relates to the field of weighing technology, and more particularly to a weighing device and weighing method for simultaneously weighing multiple objects. Background Technology
[0002] When a large number of items are removed from the nest box and placed in the weighing area, each item needs to be equipped with a sensor to weigh multiple items, which is costly. Furthermore, the gap between the weighing area and the items causes some tilting, and adjacent items can easily rub against each other, leading to inaccurate weighing.
[0003] Patent CN113167634A discloses a weighing device for weighing containers, including a weighing tool and a main body. The main body is connected to the weighing tool, and a compartment is defined within the main body. The compartment is configured to temporarily accommodate the container and has a hole defining a channel gap for introducing the container into the compartment along an inlet axis. The main body also includes multiple retaining rods to hold the container inside the compartment. However, the aforementioned weighing device has relatively few main bodies, resulting in low weighing efficiency. Furthermore, if the aforementioned weighing device has multiple main bodies, the flange edges of the objects to be weighed may still rub against each other, easily leading to inaccurate weighing. Summary of the Invention
[0004] The purpose of this invention is to address the deficiencies in the prior art by providing a weighing device and method for simultaneously weighing multiple objects, thereby improving the weighing efficiency and ensuring weighing accuracy.
[0005] To achieve the above objectives, the present invention provides a weighing device for simultaneously weighing multiple objects, including a platform for placing the objects and a measuring sensor; the platform is provided with multiple weighing areas and multiple buffer areas for placing objects to be weighed or already weighed, the multiple measuring sensors are correspondingly set with multiple weighing areas, and the layout of the weighing areas and buffer areas set by the platform corresponds to the container area of the object packaging box.
[0006] Optionally, the buffer area may be higher or lower than the weighing area.
[0007] Optionally, each metering sensor is provided with two weighing areas.
[0008] Optionally, the weighing area and the buffer area are arranged in a column, with the buffer area located on both sides of the weighing area.
[0009] Optionally, the weighing area and the buffer area are arranged in a honeycomb pattern.
[0010] Optionally, the weighing device further includes a support base, a support rod assembly, and a support member arranged sequentially from bottom to top, with the platform and the metering sensor both mounted on the support member.
[0011] Optionally, the weighing device may further include a first connector for connecting the platform and the support.
[0012] Optionally, the support base is also provided with a fixing element for fixing the weighing device.
[0013] The present invention also provides a weighing method based on the above-described weighing device, comprising the following steps:
[0014] Step 1: Take multiple items to be weighed from the container area of the item packaging box and place them in the buffer area and weighing area on one side respectively. First, weigh the items placed in the weighing area.
[0015] Step 2: After the objects in the weighing area are weighed, grab all the objects from Step 1 and put them into the weighing area and buffer area on the other side. At this time, the objects that have been weighed in Step 1 are put into the buffer area, and the objects that have not been weighed are put into the weighing area for weighing.
[0016] Step 3: After all items to be weighed have been weighed, pick up all items and put them back into the container area of the item packaging box.
[0017] Beneficial effects:
[0018] 1. This invention enables the simultaneous weighing of multiple objects by setting up multiple weighing areas and buffer areas on the platform, with multiple measuring sensors corresponding to multiple weighing areas, thereby improving the weighing efficiency of objects, saving time, and reducing costs.
[0019] 2. This invention establishes a weighing area and a buffer area at different elevations on a platform. When an object is placed on the platform for weighing, the flange edges of the objects placed in the weighing area and buffer area will not interfere with each other due to the different elevations of the two chambers, thus ensuring the weighing accuracy of the object.

[0035] See Figures 1-7 According to an embodiment of the present invention, a weighing device for simultaneously weighing multiple objects includes a platform 1 for placing objects and a measuring sensor 2; the platform 1 is provided with multiple weighing areas 3 and multiple buffer areas 4 for placing objects to be weighed or already weighed, the multiple measuring sensors 2 are correspondingly provided with multiple weighing areas 3, and the layout of the weighing areas 3 and buffer areas 4 provided on the platform 1 corresponds to the object packaging box containing area.
[0036] Specifically, the objects are often pre-filled needles, etc. The metering sensor 2 is located below the platform 1, and the weighing area 3 is connected to the metering sensor 2. Through the metering sensor 2, the weighing area 3 can weigh the objects placed inside it. The buffer area 4 is used to hold objects to be weighed or those that have been weighed, ensuring that multiple objects can be weighed at once, thus improving weighing efficiency. The layout of the weighing area 3 and the buffer area 4 is consistent with the container area of the object packaging box, so that the grippers can pick up multiple objects from the object packaging box and place them directly into the weighing area 3 and the buffer area 4 without adjusting the position of the objects.
[0037] See Figure 3 In some embodiments of the present invention, the buffer area 4 is higher or lower than the weighing area 3.
[0038] In this embodiment, by setting the height difference between the weighing area 3 and the buffer area 4, the flange edges between adjacent objects can be staggered, avoiding interference between the flanges of the objects and ensuring the weighing accuracy of the objects.
[0039] See Figure 4 and Figure 5 In some embodiments of the present invention, each metering sensor 2 is provided with two weighing areas 3.
[0040] In this embodiment, a total of 5 measuring sensors 2 are provided on the weighing device, and each measuring sensor 2 is provided with 2 weighing areas 3. It is not necessary to configure a measuring sensor 2 for each object, which can reduce the number of measuring sensors 2 provided on the weighing device and save costs.
[0041] See Figure 1 and Figure 2 In some embodiments of the present invention, the weighing area 3 and the buffer area 4 are arranged in a row, and the buffer area 4 is disposed on both sides of the weighing area 3.
[0042] In this embodiment, the platform 1 is provided with a total of 10 weighing areas 3 and 10 buffer areas 4. There are two columns of weighing areas 3 and buffer areas 4, and each column is provided with 5 weighing areas 3 or 5 buffer areas 4. The two columns of weighing areas 3 are located in the middle of the platform 1, and the two columns of buffer areas 4 are located on the left and right sides of the weighing areas 3 respectively.
[0043] See Figure 2 , Figure 6 and Figure 7 In some embodiments of the present invention, the weighing area 3 and the buffer area 4 are arranged in a honeycomb pattern. The object packaging box is also arranged in a honeycomb pattern, and the weighing area 3 and the buffer area on the platform 1 are arranged in a honeycomb pattern, consistent with the layout of the object packaging box.
[0044] See Figure 1 and Figure 3 In some embodiments of the present invention, the weighing device further includes a support base 7, a support rod assembly and a support member 6 arranged sequentially from bottom to top, with the platform 1 and the metering sensor 2 both disposed on the support member 6.
[0045] In this embodiment, the support base 7 is disposed at the bottom of the weighing device, and the support member 6 is disposed at the top of the weighing device. The support base 7 and the support member 6 are connected by a support rod assembly. The support rod assembly includes a first support rod 8 and a second support rod 9. Two second support rods 9 are disposed on the first support rod 8. By disposing of two second support rods 9, the support member 6 is stably disposed, thereby ensuring the stability of the platform 1 and the metering sensor 2 disposed on the support member 6.
[0046] See Figure 1 In some embodiments of the present invention, the weighing device further includes a first connector 5 for connecting the platform 1 and the support member 6. The measuring sensor 2 is disposed between the support member 6 and the platform 1. The first connector 5 is used to support the platform 1, preventing the weight of the platform 1 and the items placed on the platform 1 from being borne by the measuring sensor 2, which could damage the measuring sensor 2, while ensuring the weighing accuracy of the items to be weighed.
[0047] See Figure 1 and Figure 3 In some embodiments of the present invention, a fixing member 10 is further provided on the support base 7 for fixing the weighing device. The fixing member 10 is located below the support base 7 to prevent the weighing device from moving during the weighing process.
[0048] See Figure 8 and Figure 9According to an embodiment of the present invention, a weighing method based on the above-described weighing device includes the following steps:
[0049] Step 1: The gripper grabs two rows of 10 items at once from the item packaging box area and places them in the buffer area 4 and the weighing area 3 on the left. First, the items placed in the weighing area 3 are weighed.
[0050] Step 2: After the objects in weighing area 3 are weighed, the gripper will move the 10 objects from step 1 to the right and place them into a column of weighing area 3 and a column of buffer area 4 on the right. At this time, the column of objects that have been weighed is placed into buffer area 4, and the column of objects that have not been weighed is placed into weighing area 3 for weighing.
[0051] Step 3: After all 10 items have been weighed, the grippers will pick up all the items and place them back into the container area of the item packaging box.
[0052] The above are merely preferred embodiments of the present invention and do not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
