Description

Technical Field

[0001] The utility model relates to the technical field of industrial sorting, in particular to a high-precision online automatic weight checking and sorting device. Background Art

[0002] A weight sorter is a high-precision, online, automated weight checker. Online weight check has become an essential component of modern industrial production. The sorting mechanism is used to reject unqualified products. However, traditional weigh sorters are bulky and difficult to maneuver. Their feed hoppers lack automation, and their feeding methods and sorting mechanisms are insufficient for the needs of our products. Utility Model Content

[0003] The purpose of the present invention is to overcome the problems raised in the above-mentioned background technology and provide a high-precision online automatic weight checking and sorting equipment, which achieves a higher level of automation, detection accuracy and production efficiency, especially when processing glass raw materials, showing significant advantages.

[0004] The purpose of this utility model is mainly achieved through the following technical solutions:

[0005] A high-precision online automatic weight check and sorting device comprises a support frame, a support table is mounted on the support frame, a raw material placement trough is provided on the support table, a raw material guide trough is provided at the outlet of the raw material placement trough, a weighing platform is provided at the end of the raw material guide trough away from the raw material placement trough, and the weighing platform is mounted on the support table, and the weighing platform is connected to the partition guide trough; a vibration unit is provided below the raw material guide trough, and the vibration unit is mounted on the support table. The existing weight sorting machine has a low degree of automation in the feeding bin structure, and cannot perform precise automatic control according to the specific conditions of the raw materials, resulting in manual operation, affecting production efficiency and accuracy. At the same time, the feeding method and sorting mechanism design of the traditional weight sorting machine are relatively simple, and cannot effectively deal with the problem of raw material overlap or blockage, especially for glass raw materials, which can easily lead to inaccurate weight detection, thereby affecting the sorting results. In order to solve the above problems, this scheme designs a high-precision online automatic weight inspection and sorting equipment, including a support frame, which serves as a support for the overall structure. The middle part of the support frame is concave to form a cavity, and a support table is installed on the support frame. The cavity in which the support table is installed serves as an installation platform for subsequent components. A raw material placement trough is provided on the support table. The raw material placement trough is a storage mechanism for raw materials, and adopts a structure with a hollow interior, an open top, and an opening on one side wall. A raw material guide trough is provided at the outlet of the raw material placement trough, and the raw material guide trough is used to lead the raw materials in the raw material placement trough out. A weighing platform is provided at the end of the raw material guide trough away from the raw material placement trough, and the weighing platform is installed On the support table, the weighing platform is connected to a partition guide groove. The raw materials in the raw material placement groove are led out to the weighing platform to complete weighing, and then enter the corresponding partition guide groove according to the weight of the raw materials. In order to utilize gravity transportation, the raw material placement groove, the raw material guide groove, the weighing platform and the partition guide groove form a height difference, which makes the transmission efficiency higher. At the same time, a vibration unit is provided under the raw material guide groove, and the vibration unit is installed on the support table. The vibration unit assists the raw materials to be tested to smoothly enter the detection area, achieving a higher level of automation. At the same time, the combination of structures achieves higher detection accuracy and production efficiency, especially when processing glass raw materials, it shows significant advantages.

[0006] Furthermore, a heavy material guide groove is provided on the sidewall of the raw material guide groove, and the heavy material guide groove is connected to the inner cavity of the raw material guide groove. During the conveying process, raw materials may overlap due to insufficient vibration or other reasons. Therefore, the heavy material guide groove is designed. Located on the side of the raw material guide groove, it can automatically divert these overlapping material blocks to a dedicated overlapping material block placement slot, ensuring that the material blocks that enter the weighing platform for testing are single glass raw materials.

[0007] Furthermore, a support column is mounted on the support platform, and a shift fork is provided on the support column. The shift fork is located directly above the connection between the heavy material guide groove and the raw material guide groove, and the shift fork is capable of horizontal movement. A power mechanism is mounted on the support column, which can drive the shift fork to move horizontally. When overlapping material blocks are detected, the power mechanism drives the shift fork to move and push the overlapping material blocks into the heavy material guide groove. The shift fork movement function is implemented in the prior art.

[0008] Furthermore, a baffle is provided within the raw material placement trough, capable of completely closing the opening and moving vertically within the trough. A power mechanism is provided outside the trough, driving the baffle to move vertically, opening and closing the trough opening. This controls the amount of raw material entering the trough, ensuring that the amount of raw material entering the detection area is controlled each time, thereby improving detection accuracy. The baffle movement function is conventional technology.

[0009] Furthermore, a bracket is provided on the support platform, on which a detection fork is mounted. The detection fork is capable of moving to push the raw material from the weighing platform into the partitioned guide slots. A power mechanism is mounted on the bracket, which drives the detection fork to move. When the raw material enters the weighing platform and begins weighing, the detection fork moves to block the next raw material from entering the weighing platform, ensuring that only one raw material is on the weighing platform at each weighing, thereby ensuring accuracy. After weighing is completed on the weighing platform, the detection fork moves again to push the raw material from the weighing platform into the partitioned guide slots, freeing up the weighing platform for the next weighing, and repeating this process. The detection fork movement function is conventional technology.

[0010] Furthermore, a detection baffle is installed on the detection fork, and a flexible pad is installed on the side wall of the detection baffle facing the raw material guide groove. To prevent the raw material from being impacted or displaced when entering the weighing platform from the raw material guide groove, the detection baffle is used to define the final position, while the flexible pad is used to mitigate impact and ensure the integrity of the raw material.

[0011] In summary, the present invention has the following beneficial effects compared with the prior art:

[0012] (1) This solution sets an automatic baffle at the end of the raw material placement trough. When the raw materials reach the preset discharge amount, the baffle will automatically drop to block the subsequent raw materials. This design makes the supply of raw materials more accurate, reduces the involvement of manual operation, and improves the automation level of the equipment.

[0013] (2) By setting up a conveying vibration unit, the raw materials can be smoothly guided into the detection area during the conveying process, avoiding the problem of raw material blockage or stacking that may occur in traditional weight sorting machines. If overlap occurs, this solution also designs a side guide groove to automatically divert the overlapping raw materials to the overlapping material block placement groove, ensuring that the raw materials entering the weighing platform are single glass blocks. This technical solution effectively improves the accuracy of detection and avoids detection errors caused by overlap.

[0014] (3) This solution uses a high-precision weight sensor, combined with an automatic analysis structure, to ensure that only a single piece of raw material is weighed at a time, avoiding errors caused by the simultaneous detection of multiple pieces of raw material. After the detection is completed, the system controls the direction of the raw material partition guide groove through electrical signals to ensure that the raw materials can be accurately guided to the corresponding sorting area. This design not only improves the accuracy of weight sorting, but also achieves a more efficient sorting process, significantly improving production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.

[0023] In addition, it should be noted that the use of words such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above words have no special meaning and therefore cannot be understood as limiting the scope of protection of this utility model.

[0024] like Figures 1-3 As shown, this embodiment includes a support frame 1, which serves as a support for the overall structure. The middle part of the support frame 1 is concave to form a cavity. The support table is installed in the cavity, which serves as an installation platform for subsequent components. A support seat 2 is provided on the support table to support the raw material placement trough 3, so that the raw material placement trough 3 has a sufficient height. A raw material guide groove 15 is provided at the outlet of the raw material placement trough 3. The raw material guide groove 15 is connected to the outlet of the raw material placement trough 3. A weighing platform 7 is provided at the end of the raw material guide groove 15 away from the raw material placement trough 3, and the weighing platform 7 is installed on the support table. A weight sensor 17 is installed at the bottom of the weighing platform 7, and the weighing platform 7 is connected to a partition guide groove 18. The raw material placement trough 3, the raw material guide groove 15 and the weighing platform 7 form height differences in sequence, so that the glass raw materials in the raw material placement trough 3 can enter the weighing platform 7 along the raw material guide groove 15, forming automatic transportation. A vibration unit is provided below the raw material guide trough 15, and the vibration unit is divided into a lower machine vibration unit 19 and a conveying vibration unit 16. The lower machine vibration unit 19 is located at a position of the raw material guide trough 15 close to the raw material placement trough 3, and is used to vibrate the accumulated raw materials into the raw material guide trough 15, and the conveying vibration unit 16 is used to vibrate and transport the raw materials in the raw material guide trough 15.

[0025] In order to screen out overlapping raw materials, a heavy material guide groove 14 is provided on the side wall of the raw material guide groove 15, and the inner cavity of the heavy material guide groove 14 and the raw material guide groove 15 are connected. A support column is installed on the support platform, and a shift fork 12 is provided on the support column. The shift fork 12 is located directly above the connection point between the heavy material guide groove 14 and the raw material guide groove 15. The shift fork 12 can move horizontally, and the shift fork 12 is driven to move by a power mechanism to push the overlapping raw materials from the raw material guide groove 15 into the heavy material guide groove 14 and then fall into the overlapping material block placement groove 8 for collection. The overlapping material block placement groove 8 is installed on the support platform.

[0026] A baffle 4 is installed within the raw material storage trough 3, completely sealing the opening. The baffle 4 is vertically movable within the trough 3. The automatic movement of the baffle 4 allows the opening of the trough 3 to be controlled, preventing subsequent raw materials from entering and effectively separating them. This process ensures that the amount of raw materials entering the inspection area is controlled at each time, thereby improving inspection accuracy.

[0027] For ease of installation, a bracket 6 is mounted on the support platform. Mounted on bracket 6 is a detection fork, which can be moved to push the raw material from the weighing platform 7 into the partitioned guide slots 18. The detection fork pushes the weighed raw material from the weighing platform 7 into the partitioned guide slots 18, allowing the inspection process to proceed continuously. A detection baffle 13 is mounted on the detection fork, and a flexible cushioning layer is installed on the sidewall of the detection baffle 13 facing the raw material guide slot 15. This ensures accurate positioning of the glass raw material as it enters the weighing platform 7 from the raw material guide slot 15 and prevents damage to the raw material caused by impact. A display screen 5 is mounted on the support frame 1 to display the equipment's operating status and information. The sidewalls of the support frame 1 are equipped with a pipe support plate 1 and a pipe support plate 2 11. Pipe support plate 1 is located above pipe support plate 2 11. Pipe support plate 1 is provided with several upper pipe guide holes 9, and pipe support plate 2 11 is provided with several lower pipe guide holes 10, for guiding the sorted raw material into the corresponding pipes.

[0028] The specific working method of this program is:

[0029] Step 1: Raw material preparation and separation

[0030] After starting the weight checker, the operator places the glass material to be tested into the material trough 3. A baffle 4 is located at the end of this trough to control the amount of material entering. When the amount of material in the trough reaches the preset discharge volume, baffle 4 automatically descends, preventing further material from entering and effectively separating the material. This process ensures that the amount of material entering the inspection area is controlled each time, thereby improving inspection accuracy.

[0031] Step 2: Guidance and diversion

[0032] The glass material to be tested enters the next stage through a material guide trough 15. A conveyor vibration unit is installed within this trough, assisting the material in smoothly entering the testing area. If the material overlaps during transport due to insufficient vibration or other reasons, a heavy material guide trough 14 is designed on the side of the material guide trough 15 to automatically divert these overlapping pieces to a dedicated overlapping piece placement trough 8, ensuring that the pieces of glass material that ultimately enter the weighing platform 7 for testing are single pieces.

[0033] Step 3: Weight detection and sorting

[0034] The weighing system primarily consists of high-precision weight sensors. When a single material to be measured enters the weighing area, the system automatically activates a detection fork, which prevents subsequent materials from entering the weighing area to prevent interference with the current measurement process. After the weight sensor weighs the material, the resulting weight is transmitted electronically to the control system. Based on the weight detection results, the control system then uses the detection fork to push the material into the corresponding partition guide slot, directing it to the appropriate area. Finally, through a conduit connected to the material storage slot, the equipment completes the sorting of material blocks of different weights.

[0035] By improving the structural design of the feed hopper, a more automated material transport process is achieved. Specifically, an automatic baffle is installed at the end of the material trough. When the single material discharge reaches a preset amount, the baffle automatically lowers through a mechanical structure, blocking the subsequent material blocks and forming a partition. This design effectively prevents material overlap and blockage, ensuring that individual material blocks enter the inspection area accurately. This structure is not only suitable for the weight sorting machine used in this solution, but can also be extended to other inspection equipment that requires precise control of material delivery.

[0036] This design incorporates a conveying vibration unit within the material guide trough to ensure smooth material entry into the inspection area. A side slot for accumulating material blocks is also designed to handle any overlap caused by inadequate vibration or other issues. This design ensures only a single block of material remains on the weighing platform, improving weight accuracy. This vibration-assisted guide trough design can also be used in other inspection equipment with stringent requirements for material alignment and separation, such as packaging inspection equipment and surface defect detection equipment.

[0037] By designing a conduit connected to the raw material placement trough, raw materials can be directed to the appropriate partitions based on weight test results, automatically separating qualified and unqualified products. This design not only simplifies the operation process but also improves the mobility and flexibility of the equipment, facilitating rapid reorganization of the production line. This movable partition guide trough system can be applied to a variety of production equipment that requires sorting based on test results, such as color sorters and automated packaging machines.
