Description

[0002] Glass raw material batching scale is a metering device specially used for accurately weighing various glass raw materials and configuring them in specific proportions during the glass production process. In glass manufacturing, a variety of different raw materials, such as quartz sand, soda ash, limestone, feldspar, etc., need to be mixed according to strict formula ratios. Glass raw material batching scales can weigh each raw material individually through advanced weighing sensors and precise measurement systems. After weighing, the proportions are transported to the transmission belt below. Multiple groups of batching scales can be combined to complete the batching and transportation of glass raw materials, realizing automatic and precise batching.

[0003] When a glass raw material batching scale is weighing raw materials, the glass material storage tank above it usually uses a feeder to feed the stored raw materials into the tank for weighing. When the scale reaches the specified weight, the feeder stops feeding and completes the quantitative weighing. However, in the actual operation process, since the materials are usually granular materials such as sand and limestone, the feeder is prone to feeding too little or too much during the feeding process, resulting in out-of-tolerance weighing problems. The proportion requirement is usually within one two thousandth, and the weighing accuracy is insufficient.

[0039] In the prior art, when weighing raw materials, glass raw material batching scales usually use a glass material storage tank above them to feed the stored raw materials into the tank for weighing. When the scale reaches the specified weight, the feeder stops feeding and completes the quantitative weighing. However, in actual operation, since the materials are usually granular materials such as sand and limestone, the feeder is prone to feeding too little or too much during the feeding process, resulting in out-of-tolerance weighing problems. The ratio requirement is usually within one in two thousand, and the weighing accuracy is insufficient. The existing glass raw material batching scales have insufficient automatic adjustment capabilities for out-of-tolerance, and manual adjustment is time-consuming and labor-intensive, affecting project progress and efficiency.

[0040] The invention provides an automatic over-tolerance adjustment device for a batching scale.

[0041] See also Figures 1 to 9 As shown, in one embodiment of the present invention, the over-tolerance automatic adjustment device of the batching scale includes a raw material weighing scale body 1, a raw material storage tank 2 and a PLC controller 10, wherein a feeder is connected to the bottom of the raw material storage tank 2, and the feeder is used to transport the raw materials in the raw material storage tank 2 to the raw material weighing scale body 1, and a load-bearing mounting frame 3 is provided above the raw material weighing scale body 1; a guide rail assembly is provided at the bottom of the load-bearing mounting frame 3, and a telescopic control assembly 5 is connected to the guide rail assembly, and an over-tolerance automatic gripper 6 is connected to the bottom of the telescopic control assembly 5, and the load-bearing mounting frame 3 is also connected to a loading bucket 7 and an over-tolerance replenishment tank 8, and the over-tolerance automatic gripper 6 is used to transport the raw materials inside the raw material weighing scale body 1 to the loading bucket 7, and the over-tolerance replenishment tank 8 is located above the raw material storage tank 2 and is used to transport the raw materials to the raw material storage tank 2; a level meter 9 is provided inside the raw material weighing scale body 1, and the PLC controller 10 is electrically connected to the raw material weighing scale body 1, the guide rail assembly, the telescopic control assembly 5, the over-tolerance automatic gripper 6, the over-tolerance replenishment tank 8 and the level meter 9 respectively.

[0042] In the specific implementation process, the telescopic control component 5 is retractable as a whole, and controls the lifting and lowering of the over-tolerance automatic gripper 6, and realizes translation through the guide rail component, so that the raw materials can be grabbed from the raw material weighing scale body 1 and transferred to the loading bucket 7. The over-tolerance automatic gripper 6 as a whole opens and closes to take and put the raw materials, and the PLC controller controls the coordination between the various structures to automatically complete the over-tolerance adjustment of the raw materials, greatly improving the production efficiency. In addition, it should be noted that the raw material weighing scale body 1 has the ability to automatically weigh, so as to automatically weigh the raw materials transported to the raw material weighing scale body 1 by the raw material storage tank 2.

[0043] The technical solution of the present invention completes the weighing of raw materials by conveying the raw materials in the raw material storage tank 2 to the raw material weighing scale body 1 through a feeder. The load-bearing mounting frame 3 plays a supporting role. The operation of the guide rail assembly can drive the telescopic control assembly 5 and the over-tolerance automatic gripper 6 to move horizontally. The operation of the telescopic control assembly 5 can push the over-tolerance automatic gripper 6 to move and fall into the raw material weighing scale body 1. The over-tolerance automatic gripper 6 grabs the overweight raw materials in the raw material weighing scale body 1. The material level meter 9 cooperates to detect the material level height of the raw materials in the tank body, so that the over-tolerance automatic gripper 6 grabs stably and takes out the overweight raw materials. The filling bucket 7 can store and divert excess raw materials, and the over-tolerance replenishment tank 8 can discharge raw materials. When the weighed material in the raw material weighing scale body 1 is less than the specified weight, the over-tolerance replenishment tank 8 can replenish the raw materials. The PLC controller 10 can remotely and automatically control the overall operation without manual weighing and adjustment, so that the device can remove or supplement materials for out-of-tolerance weighing of the batching scale, thereby improving the weighing accuracy. The overall degree of automation is high, which improves the convenience and efficiency of production operations.

[0044] In one embodiment, the guide rail assembly, the telescopic control assembly 5 and the out-of-tolerance automatic gripper 6 are each provided with two corresponding groups, wherein the volumes of the two out-of-tolerance automatic grippers 6 are different.

[0045] In the specific implementation process, the volume of one of the two over-tolerance automatic grippers 6 is larger than the volume of the other one, and one of the over-tolerance automatic grippers 6 can be controlled to grab the raw materials according to the overweight situation. For example, when the overweight is large, the over-tolerance automatic gripper 6 with a large volume can be used for grabbing; when the overweight is less than the volume of the over-tolerance automatic gripper 6 with a larger volume, the over-tolerance automatic gripper 6 with a smaller volume can be driven to grab; when the overweight raw materials are grabbed multiple times to close to the weighing value, the over-tolerance automatic gripper 6 with a smaller volume can be used for grabbing to improve the weighing accuracy. Of course, it is understandable that the over-tolerance automatic gripper 6 can perform multiple grabbing operations, and it is convenient to grab and take materials, convenient to adjust the over-tolerance, and has high weighing accuracy.

[0046] In one embodiment, the guide rail assembly includes an electric guide rail 4, which is bolted and fixed to the bottom of the load-bearing mounting frame 3. The electric guide rail 4 is driven and connected to the telescopic control assembly 5, and drives the telescopic control assembly 5 to move. The telescopic control assembly 5 also drives the out-of-tolerance automatic gripper 6 to move. The volume of one of the two out-of-tolerance automatic grippers 6 is 1 liter to 5 liters, and the volume of the other one is 4 liters to 10 liters.

[0047] In the specific implementation process, the load-bearing mounting frame 3 is fixedly suspended on the top of the wall to improve the stability of the load-bearing mounting frame 3, so that the load-bearing mounting frame 3 can stably support the material replenishment and material taking equipment, and the electric and stable push of the electric guide rail 4 to move the telescopic control component 5 and the over-tolerance automatic gripper 6 can be stably displaced in the thread of the electric guide rail 4, and the adaptability is excellent. Since the two over-tolerance automatic grippers 6 have a volume of 1 liter to 5 liters and a volume of 4 liters to 10 liters, respectively, the large-volume gripper or the small-volume gripper can be controlled to perform the raw material grabbing operation according to the over-tolerance weighing of the raw material weighing scale body 1, and the adaptability is excellent.

[0048] In one embodiment, the telescopic control assembly 5 includes a load-bearing rod 51, a telescopic load-bearing tube 52 and two telescopic push cylinders 53. The load-bearing rod 51 is installed at the bottom of the guide rail assembly, the telescopic load-bearing tube 52 is slidably sleeved on the load-bearing rod 51, the top ends of the two telescopic push cylinders 53 are hinged to the guide rail assembly, the bottom ends of the two telescopic push cylinders 53 are hinged to both sides of the telescopic load-bearing tube 52, and the bottom of the telescopic load-bearing tube 52 is connected to the out-of-tolerance automatic gripper 6.

[0049] During the specific implementation process, the load-bearing rod 51 and the telescopic load-bearing tube 52 play the role of telescopic and load-bearing support. The load-bearing rod 51 can support the telescopic load-bearing tube 52, and the telescopic load-bearing tube 52 is pushed and supported by the telescopic push cylinders 53 on both sides. When the telescopic push cylinders 53 on both sides are running, the telescopic load-bearing tube 52 can be pushed to make the telescopic load-bearing tube 52 move up and down on the load-bearing rod 51, so that the telescopic control component 5 can drive the out-of-tolerance automatic gripper 6 to perform lifting operations, which has excellent practicality.

[0050] Furthermore, both ends of the telescopic push cylinder 53 are hinged with hinged bearing seats, and the slider end of the guide rail assembly and the telescopic bearing tube 52 are respectively hingedly connected through the hinged bearing seats, so that when the telescopic push cylinder 53 is in operation, it can adaptably push the telescopic bearing tube 52 to rise and fall, and maintain stability, not easy to be damaged or broken, and has excellent practicality. In the specific implementation process, the telescopic push cylinder 53 is a hydraulic, electric or pneumatic telescopic cylinder, and is connected to a corresponding power system.

[0051] In one embodiment, the out-of-tolerance automatic gripper 6 includes a carrying platform 61, a carrying grab hopper 62 and a hydraulic cylinder 63, wherein the carrying platform 61 is fixedly installed at the bottom of the telescopic control assembly 5, two carrying grab hoppers 62 are provided, and each carrying grab hopper 62 is hinged with a hydraulic cylinder 63, the top of the hydraulic cylinder 63 is connected to the carrying platform 61, the two carrying grab hoppers 62 are symmetrically arranged and respectively hingedly installed at the bottom of the carrying platform 61, and the two carrying grab hoppers 62 are adapted to and surround each other to form a accommodating cavity for grabbing raw materials.

[0052] During the specific implementation process, the supporting platform 61 can be hinged to support two supporting grab hoppers 62, and the two supporting grab hoppers 62 are controlled by the hydraulic cylinder 63 to move closer to or farther away from each other. When the two supporting grab hoppers 62 move away from each other, the entire grabbing clamp opens to deeply grab the raw materials. Running the two hydraulic cylinders 63 can push the two supporting grab hoppers 62 to move closer and merge into an integral hopper. During the merging process, the raw materials can be collected and taken out, thereby facilitating the grabbing and collecting operations of the raw materials.

[0053] Furthermore, the edges of the two load-bearing grab hoppers 62 are provided with anti-leakage protection strips to make the two load-bearing grab hoppers 62 seal and fit. Specifically, after the two load-bearing grab hoppers 62 are closed, the anti-leakage protection strips play a role in preventing leakage of raw materials, improving the sealing of the entire hopper, and can be adapted to grab raw materials with smaller diameters, improve the stability of grabbing, avoid leakage in the process of grabbing raw materials and affect the accuracy of weighing adjustment, and can also improve the applicability of the device.

[0054] In one embodiment, the loading hopper 7 includes a hanging hopper 71, a feeding pipe 72 and a hanging mounting rod 73, the hanging mounting rod 73 respectively connects the hanging hopper 71 and the supporting mounting frame 3, the feeding pipe 72 is connected and arranged at the bottom of the hanging hopper 71, and the hanging hopper 71 is located on one side of the raw material weighing scale body 1.

[0055] In the specific implementation process, the bottom end of the hanging mounting rod 73 is connected to the hanging hopper 71, and the top end is connected to the load-bearing mounting member 3, so that the hanging hopper 71 can be hung below the load-bearing mounting frame 3. The hanging hopper 71 plays the role of collecting materials. Specifically, after the over-tolerance automatic gripper 6 completes the grabbing of overweight raw materials, it can be moved to the top of the hanging hopper 71. After the over-tolerance automatic gripper 6 is opened, the raw materials fall into the hanging hopper 71, and the hanging hopper 71 collects and stores the materials. Furthermore, a discharge pipe 72 is provided at the bottom of the hanging hopper 71, and the discharge pipe 72 guides the materials to the ground. Buckets or other filling tools are placed on the ground to collect and fill the raw materials. Through the collection and guiding of the filling hopper 7, dust is not easily raised during the overall process, and the equipment runs stably, reducing the waste and loss of raw materials.

[0056] In one embodiment, the over-tolerance feeding tank 8 includes a feeding tank body 81, a hanging rod body 82, a driving auger 83 and a discharging motor 84, the rod body 82 is respectively connected to the feeding tank body 81 and the supporting mounting frame 3, the driving auger 83 is rotatably connected to the inside of the feeding tank body 81, the bottom of the driving auger 83 extends to the discharging pipe at the bottom of the feeding tank body 81, the discharging motor 84 is arranged at the top of the feeding tank body 81, the top of the driving auger 83 extends out of the feeding tank body 81 and is connected to the output end of the discharging motor 84, and the discharging pipe at the bottom of the feeding tank body 81 is L-shaped.

[0057] During the specific implementation process, the raw materials matching the raw material storage tank 2 are stored in the feeding tank body 81. The feeding tank body 81 is suspended at the bottom of the supporting mounting frame 3 by the suspension rod body 82, and the feeding tank body 81 is correspondingly arranged above the raw material weighing scale body 1. The operation of the discharging motor 84 can drive the driving auger 83, which can stably drive the raw materials in the feeding tank body 81 to be discharged. The discharging pipe at the bottom of the feeding tank body 81 can discharge the materials stably and accurately. Since the discharging pipe at the bottom of the feeding tank body 81 is L-shaped, the discharging is more accurate. When the weighed material in the raw material weighing scale body 1 is less than the specified weight, the raw material can be replenished by the out-of-tolerance feeding tank 8.

[0058] In one embodiment, a trigger sensor 11 is provided on the electric guide rail 4 , two trigger sensors 11 are provided, and the two trigger sensors 11 are respectively located above the raw material weighing scale body 1 and the loading bucket 7 , and the trigger sensor 11 is electrically connected to the PLC controller 10 .

[0059] In the specific implementation process, the main body 1 of the raw material weighing scale automatically weighs the raw materials, and in the process of adjusting the tolerance, the main body 1 of the raw material weighing scale always and in real time weighs the raw materials, so as to achieve the effect of accurately weighing and discharging the materials. Two trigger sensors 11 are respectively located above the main body 1 of the raw material weighing scale and the loading bucket 7. When the automatic gripper 6 of the tolerance takes the materials in the tank and discharges the materials in the loading bucket 7, the trigger positioning of the trigger sensor 11 is used to make the automatic gripper 6 of the tolerance stably grasp and discharge the materials, and it is not easy to leak the materials, and the grasping is stable and convenient. The entire automatic adjustment device of the batching scale of tolerance is controlled by the PLC controller 10, and the degree of automation is relatively high.

[0060] This technical solution is achieved by setting up a raw material weighing scale body 1 and a raw material storage tank 2. The raw material storage tank 2 plays the role of storing glass raw materials. The raw material storage tank 2 feeds the glass raw materials into the raw material weighing scale body 1 through a feeder. When the weight of the raw materials fed into the raw material weighing scale body 1 reaches a specified weight, the feeder stops feeding and the raw material weighing operation is completed.

[0061] It should be noted that, since glass raw materials are usually granular raw materials, the feeding accuracy is relatively insufficient, and out-of-tolerance phenomena are prone to occur. This technical solution can support and bear the electric guide rail 4 by setting a load-bearing mounting frame 3 above the main body 1 of the raw material weighing scale. The operation of the electric guide rail 4 can drive the telescopic control component 5 and the out-of-tolerance automatic gripper 6. When there are too many raw materials in the main body 1 of the raw material weighing scale, the electric guide rail 4 can be operated to move the out-of-tolerance automatic gripper 6 to the top of the main body 1 of the raw material weighing scale. The operation of the telescopic control component 5 can push the out-of-tolerance automatic gripper 6 to move down into the main body 1 of the raw material weighing scale. The overweight raw materials in the main body 1 of the raw material weighing scale are grabbed by the overweight automatic gripper 6. The main body 1 of the raw material weighing scale is provided with a material level meter 9, which can stably detect the material level height of the raw materials in the tank body, so that the telescopic control component 5 can stably drive the out-of-tolerance automatic gripper 6 to move to the material in the tank, and then the out-of-tolerance automatic gripper 6 is operated to grab the raw materials and take out the overweight raw materials.

[0062] After the over-tolerance automatic gripper 6 completes grabbing of the overweight raw material, the telescopic control assembly 5 controls the upward displacement, takes out the raw material weighing scale body 1, and then is driven by the electric guide rail 4 to move above the loading bucket 7, and the raw material in the over-tolerance automatic gripper 6 falls into the loading bucket 7 for storage, completing the overweight grabbing and weight reduction operation of the raw material. The loading bucket 7 is hoisted on the load-bearing mounting frame 3, and is convenient for installation and unloading.

[0063] According to the overweight situation of the raw material weighing scale body 1, single grabbing or multiple grabbing can be performed, and the electric guide rail 4, telescopic control component 5 and over-tolerance automatic grabbing clamp 6 are all two corresponding groups. According to the overweight situation, the large-volume grabbing clamp or the small-volume grabbing clamp can be used for raw material grabbing operations.

[0064] An over-tolerance feeding tank 8 is provided on the side of the bearing mounting frame 3. When the weighed material in the raw material weighing scale body 1 is less than the specified weight, the over-tolerance feeding tank 8 can be used to feed the raw material. The over-tolerance feeding tank 8 includes a feeding tank body 81, a hanging rod body 82, a driving auger 83 and a discharging motor 84. The feeding tank body 81 stores raw materials that match the raw material storage tank 2. The feeding tank body 81 is suspended at the bottom of the bearing mounting frame 3 by the hanging rod body 82, and the feeding tank body 81 is correspondingly arranged above the raw material weighing scale body 1. The running of the discharging motor 84 can drive the driving auger 83, which can stably drive the raw materials in the feeding tank body 81 to discharge, and the discharging pipe at the bottom of the feeding tank body 81 can discharge the materials stably and accurately. The discharge pipe at the bottom of the feeding tank body 81 is L-shaped. Compared with the vertical discharge pipe, the discharge pipe in this embodiment is L-shaped, which makes it easier to control the discharge and prevents the raw materials from falling directly from the feeding tank body 81 into the raw material weighing scale body 81, thereby improving the accuracy of the discharge of the out-of-tolerance feeding tank 8.

[0065] The over-tolerance automatic adjustment device provided by the technical solution can perform material grabbing or material replenishment operations when the weight exceeds or is less than the specified weight. The whole is stably controlled by the PLC controller 10, and the over-tolerance weighing of the batching scale can be adjusted by removing materials or replenishing materials, thereby improving the weighing accuracy, and the overall degree of automation is high, which improves the convenience and efficiency of production operations.
