The main disadvantages of manual batching are: low efficiency, high cost, difficult to guarantee product quality, and strict requirements on the technical experience of operators. Manual batching requires experienced operators, a large number of operators, a relatively complicated batching process, and many auxiliary tools and auxiliary equipment. However, the efficiency will decrease with the fatigue of the operators. Auxiliary equipment will cause misoperation and accidental injury to operators, and auxiliary equipment is time-consuming and power-consuming, such as forklifts, conveyors, overhead cranes, etc. The original manual batching has cumbersome material weight matching and requires countless screening and weighing to complete the batching work. Summary of the invention

[0003] In view of the above technical problems, the present invention provides a bulk material batching device and method for supplementing small materials. The device adopts the functions of online weighing, online screening and online calibration, has a high degree of automation, and the weighing and metering data is more stable.

[0004] To achieve the above object, the present invention adopts the following technical solutions: A bulk material batching device for supplementing small materials, comprising: A step array machine, comprising a silo and a lifting component located below the silo, wherein a lifting feeding step connected to the lifting component is provided in the silo, and a conveyor and a rejecting component are provided at the discharge end of the lifting feeding step; A material correction mechanism, connected to the discharge end of the conveyor, includes a correction reversing conveyor and a correction conveyor, and is used to correct the material; A dynamic weighing mechanism connected to the discharge end of the material correction mechanism; The weighing and caching mechanism includes a weighing and caching conveyor and several sets of platform scales and material sorting robots arranged in a one-to-one correspondence. The weighing and caching conveyor is connected to the discharge end of the dynamic weighing mechanism and conveys the materials that meet the weight standard to the corresponding position of the platform scale. The material sorting robot is used to transfer the materials into the platform scale for data statistics and weight analysis and wait for batching. A finished material weighing mechanism, connected to the discharge end of the weighing buffer conveyor, for receiving the material from the platform scale; The small material disc vibrating feeder is arranged beside the finished material weighing mechanism and is used to supply small materials to the finished material weighing mechanism.

[0005] In the bulk material batching device, preferably, the lifting component comprises a lift cylinder and a linear slide rail located above the lift cylinder, and the lifting feeding step is connected to the linear slide rail; and / or, The rejecting component comprises a rejecting cylinder and a material rejecting plate connected to the rejecting cylinder, and the material rejecting plate is used for performing a first rejecting of the protruding material.

[0006] In the block material batching device, preferably, the material correction mechanism also includes a correction disc telescopic mechanism, and the correction disc telescopic mechanism includes a cylinder and a linear slider connected to the cylinder, and the linear slider is provided with a motor reducer and a correction disc.

[0007] The block material batching device, preferably, the material correction mechanism also includes an over-conveyor, which is arranged downstream of the correction disc telescopic mechanism, and laser beam switches are fixed on both sides of the over-conveyor to sense whether there is material passing by, and then determine the feeding method.

[0008] In the bulk material batching device, preferably, the weighing cache mechanism further comprises a weighing cache line bracket and a driver control cabinet and a servo driver installed on the weighing cache line bracket; and / or, The material input end of the weighing buffer conveyor is provided with a laser beam detection switch, and each of the platform scales is provided with an independent weighing buffer beam detection switch.

[0009] The bulk material batching device, preferably, the material sorting robot includes a linear robot and a sorting gripper transmission-connected to the linear robot, and the linear robot is fixed to the top of the weighing cache line bracket through a robot fixed bottom plate.

[0010] In the block material batching device, preferably, the finished material weighing mechanism comprises a weighing system bracket, and the weighing system bracket is provided with a check weighing scale, a weighing arc valve bin, a re-checking scale and a material receiving port in sequence from top to bottom.

[0011] The bulk material batching device is preferably provided with a door switch cylinder and a synchronous gear on the weighing arc valve hopper, which are used to push the door of the weighing arc valve hopper to open for unloading and put the material into the re-inspection scale.

[0012] The bulk material batching device is preferably provided with an electric lift on the weighing system bracket. When the checkweigher and the re-checkweigher need to be calibrated, the electric lift descends to place the checkweigher calibration weights and the re-check calibration weights on the re-checkweigher in the weight support plate fixed on the weighing arc valve bin for calibration. After the calibration is completed, the electric lift drags the checkweigher calibration weights and the re-check calibration weights to lift them to complete the calibration work.

[0013] A second aspect of the present invention provides a batching method of a bulk material batching device for replenishing small materials, comprising the following steps: Step 1: Slow feed screening a: The feeding mechanism puts the block material into the step array machine. The material is stored in the silo and driven by the lifting component to lift the feeding step up and down to feed and perform preliminary screening. The lifted material enters the conveyor. The rejection component removes the high material for the first time. The rejected material returns to the silo, and the highly qualified material continues to move along the conveyor direction; b: Highly qualified materials enter the material correction mechanism. Materials with inconsistent directions are corrected for the first time during the conveying process by the correction reversing conveyor. The materials are corrected by the working principle that the correction conveyor rotates forward and the correction reversing conveyor rotates backward. If there is any missed material, it is corrected for the second time by the correction disc telescopic mechanism. The correction disc telescopic mechanism has the function of breaking the arch. The corrected materials enter the over-conveyor; c: After the qualified materials are screened and enter the transition conveyor, the laser beam switches fixed on both sides of the transition conveyor sense whether there are materials, and the materials are transported to the conveyor. After weighing, the materials transmit the weight information to the PLC for calculation, and then enter the weighing buffer conveyor; d: Materials entering the weighing buffer conveyor, materials that do not meet the weight standards after weighing are directly conveyed to the checkweigher by the weighing buffer conveyor, and materials that meet the weight standards are sequentially sent to the corresponding center position of the scale through the weighing buffer cross-shooting detection switch. The material sorting robot is used to transfer the materials into the scale for data statistics and weight analysis and wait for batching. Unqualified materials are conveyed to the finished product silo. After several scales have materials, they enter the second step of indiscriminate feeding; Step 2: Indiscriminate feeding e: This step is the same as step a in the first step; f: Highly qualified materials enter the material correction mechanism, and the overall conveying speed is increased to 3 times that of the first step, and indiscriminate feeding is carried out. When the weight reaches the predetermined value range, the system enters the next finished product screening step; Step 3: Finished product screening g: At this time, the overall conveying system stops working. After the system automatically calculates, the small material disc vibrating feeder will automatically start to replenish small materials until the weight reaches the total weight data of several stations of the material finished product weighing mechanism. The weighing buffer mechanism calculates the current weight, and the material sorting robot pushes the material to the weighing buffer conveyor and transports it to the material finished product weighing mechanism according to the instructions received; After the material weight on the check weighing scale is qualified, the material in the weighing arc valve hopper is unloaded by pushing the control hopper door open through the synchronous gear, and the material is put into the receiving port. When the weight on the check weighing scale is the same as that on the re-check weighing scale or is within the allowable error range, the material is put into the receiving port and falls into the finished product container and is transported out through the finished product conveyor.

[0014] The present invention adopts the above technical solution, which has the following advantages: 1.

The main disadvantages of manual batching are: low efficiency, high cost, difficult to guarantee product quality, and strict requirements on the technical experience of operators. Manual batching requires experienced operators, a large number of operators, a relatively complicated batching process, and many auxiliary tools and equipment are used. However, the efficiency will be reduced according to the fatigue of the manual labor.

[0023] Based on the above technical problems, the present invention provides a bulk material batching device and method, which adopts the functions of online weighing, online screening and online calibration, has a high degree of automation, and the weighing and metering data is more stable.

[0024] like Figure 1 , 3As shown in Figures 5 and 6, the bulk material batching device for replenishing small materials involved in the present invention comprises: a step array machine 1, comprising a silo and a lifting component located below the silo, a lifting feeding step 12 connected to the lifting component is arranged in the silo, and a conveyor 13 and a rejecting component are arranged at the discharge end of the lifting feeding step 12; a material correction mechanism 2, connected to the discharge end of the conveyor 13, comprising a correction reversing conveyor 22 and a correction conveyor 23, for twisting the material; a dynamic weighing mechanism 3, connected to the discharge end of the material correction mechanism 2; a weighing buffer mechanism 4, comprising a weighing buffer conveyor 31 and ten sets of platform scales 34 and material sorting robots 35 arranged in one-to-one correspondence. The materials are transported to the weighing buffer conveyor 31 through the dynamic weighing mechanism 3. The materials within the weight range are pushed into the platform scale 34 by the material sorting robot 35. The materials that are not within the weight range are sent to the material finished product weighing mechanism 5 through the weighing buffer conveyor 31. The material finished product weighing mechanism 5 is connected to the discharge end of the weighing buffer conveyor 31 for receiving the materials from the platform scale 34; the small material disc vibrating feeder 6 is arranged next to the material finished product weighing mechanism 5 for replenishing small materials to the material finished product weighing mechanism 5.

[0025] Furthermore, if Figure 3 As shown, the lifting component includes a lift cylinder 9 and a linear slide rail 10 located above the lift cylinder 9, and the lifting feeding step 12 is connected to the linear slide rail 10; the rejecting component includes a rejecting cylinder 17 and a material rejecting plate 19 connected to the rejecting cylinder 17, and the material rejecting plate 19 is used to perform the first rejection of the protruding material.

[0026] Furthermore, if Figure 4 As shown, the material correction mechanism 2 also includes a correction disc telescopic mechanism 24 and an over-conveyor 27. The correction disc telescopic mechanism 24 includes a cylinder and a linear slider connected to the cylinder, and the linear slider is provided with a motor reducer 25 and a correction disc 26. The over-conveyor 27 is arranged downstream of the correction disc telescopic mechanism 24. Laser beam switches are fixed on both sides of the over-conveyor 27 to sense whether there is material passing through, and then determine the feeding mode.

[0027] Furthermore, if Figure 5 As shown, the weighing cache mechanism 4 also includes a weighing cache line bracket 28 and a driver control cabinet 29 and a servo driver 30 installed on the weighing cache line bracket 28; the material input end of the weighing cache conveyor 31 is provided with a laser beam detection switch 32, and each platform scale 34 is provided with an independent weighing cache beam detection switch 33.

[0028] Furthermore, if Figure 6As shown, the material sorting robot 35 includes a linear robot 37 and a sorting gripper 39 which is transmission-connected to the linear robot 37 . The linear robot 37 is fixed on the top of the weighing buffer line bracket 28 through a robot fixing base plate 38 .

[0029] Furthermore, if Figure 8 , 9 As shown, the material finished product weighing mechanism 5 includes a weighing system bracket 51, and the weighing system bracket 51 is provided with a check weighing scale 44, a weighing arc valve bin 52, a recheck weighing scale 47 and a material receiving port 48 in sequence from top to bottom. The weighing arc valve bin 52 is also provided with a bin door switch cylinder 54 and a synchronous gear 55, which are used to push the bin door of the weighing arc valve bin 52 to open for unloading, and put the material into the recheck weighing scale 47. The weighing system bracket 51 is also provided with an electric lift 50 and a weight support plate 53. When the check weighing scale 44 and the recheck weighing scale 47 need to be calibrated, the electric lift 50 descends to place the check weighing calibration weight 45 of the check weighing scale 44 and the recheck weighing calibration weight 46 of the recheck weighing scale 47 in the weight support plate 53 for calibration. After the calibration is completed, the electric lift 50 drags the check weighing calibration weight 45 and the recheck weighing calibration weight 46 to rise, completing the calibration work.

[0030] The following is combined with Figure 1-10 The batching method of the bulk material batching device of the present invention is described in detail.

[0031] Step 1: Slow feed screening like Figure 1-4 As shown, the material is put into the step array machine 1 through the feeding mechanism to put the block material into the step array machine 1, and the material is stored in the elevator silo 11. The elevator cylinder 9 drives the linear slide 10 and the lifting feeding step 12 to move up and down reciprocatingly to feed the material and perform preliminary screening. The lifted material enters the conveyor 13 above the step array machine 1, and the excess material is blocked by the material baffle 18 to prevent overflow. The rejection cylinder 17 fixed by the rejection cylinder bracket 14 drives the material rejection plate 19 to remove the high material for the first time according to the program control, and the rejected material returns to the elevator silo 11. The highly qualified material continues to move along the conveyor 13. If there is still unqualified material, it will move to the height limit baffle 20 to be blocked and rejected again. The rejected material returns to the elevator silo 11 along the material return drum chute 16.

[0032] Highly qualified materials enter the material correction mechanism 2, Figure 5The correcting reversing conveyor 22 and the correcting conveyor 23 fixed at the upper end of the middle correcting mechanism bracket 21 convey the materials along the route. The materials with inconsistent directions will be straightened for the first time during the conveying process by the correcting reversing conveyor 22. The materials will be twisted by the working principle that the correcting conveyor 23 rotates forward and the correcting reversing conveyor 22 rotates backward. When there are too many materials, some materials will be missed. At this time, the correcting disc telescopic mechanism 24 will be corrected again. The correcting disc telescopic mechanism 24 is composed of a cylinder and a linear slider. The motor reducer 25 and the correcting disc 26 fixed on the top are pushed out to a position suitable for the width of the material to correct the material. If the material is stuck, this mechanism will reciprocate back and forth to realize the function of automatic arch breaking. The motor reducer 25 and the correcting disc 26 on the top are driven by the correcting disc telescopic mechanism 24 to telescope back and forth, and the materials are reciprocated and dredged. At this time, the bridged materials will automatically separate and continue to move forward. The materials that have been corrected many times enter the excessive conveyor 27.

[0033] After the qualified materials are screened and enter the transition conveyor 27, the laser beam switches fixed on both sides of the transition conveyor 27 sense whether there are materials. When the materials pass through continuously, the transition conveyor 27 enters the intermittent feeding mode and pulls the materials apart by a uniform distance. The purpose is to give the dynamic weighing mechanism 3 a more stable time to make weighing records. After weighing, the weight information of the material is transmitted to the PLC for calculation and enters the weighing cache mechanism 4.

[0034] Figure 6It is the main structure of the weighing cache mechanism 4. A driver control cabinet 29 is installed in the middle of the weighing cache line bracket 28. The driver control cabinet 29 is designed as a sealed structure with convection axial flow fans installed on both sides to cool the servo driver 30. This link is designed with ten sets of scales 34 and ten sets of material sorting robots 35 installed accordingly. Each set has an independent weighing cache shooting detection switch 33 to detect the passing materials. Qualified materials are first detected by the laser beam detection switch 32 and then enter the weighing buffer conveyor 31. After being weighed, materials that do not meet the weight standard are directly conveyed to the checkweigher 44 by the weighing buffer conveyor 31. Materials that meet the weight standard are fed to the platform scale 34 in the order of 1-10 through the weighing buffer beam detection switch 33. For example, after the materials are sensed by the weighing buffer beam detection switch 33, they are pushed to the weighing buffer conveyor 31 by the linear robot 37 transmission sorting gripper 39. The material sorting robot 35 adopts a ball screw type linear robot 37 driven by a servo motor. The robot fixing bottom plate 38 is firmly fixed on the top of the weighing buffer line bracket 28, and the outside is sealed with an acrylic cover plate 36. The main components of the platform scale 34 are the platform scale base 42 fixed on the bottom plate in the middle of the equipment, the sensor base 41 connects the platform scale base 42 and the weighing sensor 40, and the weighing sensor 40 is connected to the platform scale table 43. It is a set of standard platform scales. The materials passing through this process preferably enter 10 buffer mechanisms. Materials that are not of the pre-selected weight are conveyed to the finished material weighing mechanism 5 through the weighing buffer conveyor 31 for feeding and weighing. After all 10 scales 34 are filled with materials, they enter the second step of the indiscriminate feeding system.

[0035] Step 2: Fast and indiscriminate feeding like Figure 1-4 As shown, the material is put into the step array machine 1 through the feeding mechanism to put the block material into the step array machine 1, and the material is stored in the elevator silo 11. The elevator cylinder 9 drives the linear slide 10 and the lifting feeding step 12 to move up and down to feed the material and perform preliminary screening. The lifted material enters the conveyor 13 above the step array machine 1, and the excess material is blocked by the material baffle 18 to prevent overflow. The rejection cylinder 17 fixed by the rejection cylinder bracket 14 drives the material rejection plate 19 to remove the high material for the first time according to the program control, and the rejected material returns to the elevator silo 11. The highly qualified material continues to move along the conveyor 13. If there is still unqualified material, it will move to the height limit baffle 20 to be blocked and rejected again. The rejected material returns to the elevator silo 11 along the material return drum chute 16.

[0036] Highly qualified materials enter the material correction mechanism 2, and the overall conveying speed is accelerated to 3 times that of the previous step, and indiscriminate discharging is carried out. Indiscriminate feeding means that the materials can be fed quickly regardless of whether they are horizontal or vertical. The materials will be transported to the finished product weighing mechanism. When the weight reaches the predetermined value range, the system enters the next finished product screening function.

[0037] Step 3: Finished product screening like Figure 1 , 2 9, the overall conveying system is suspended at this time. After the system automatically calculates, the small material disc vibrating feeder 6 will automatically start to replenish small materials until the weight reaches the total weight data of several stations of the material finished product weighing mechanism 5. The weighing buffer mechanism 4 calculates the current weight, and the material sorting robot 35 pushes the material to the weighing buffer conveyor 31 and conveys it to the material finished product weighing mechanism 5 through the obtained instructions. Because the feeding method is that the material is smashed into the silo, the weighing structure of the check weighing scale 44 and the re-check weighing scale 47 is designed as a hoisting weighing module 49, and the lower part of the sensor is connected by a chain.

[0038] After the material weight on the check weighing scale 44 is qualified, the material in the weighing arc valve bin 52 is pushed by the synchronous gear 55 and the bin door switch cylinder 54 to control the bin door to open for unloading, and the material is put into the re-inspection scale 47. The working principle of the re-inspection scale 47 is the same as that of the check weighing scale 44. When the weight of the check weighing scale 44 is the same as that of the re-inspection scale 47 or is within the allowable error range, the re-inspection scale 47 puts the material into the receiving port 48 and falls into the finished product container 7, and is transported out of the mechanism through the finished product conveyor 8.

[0039] Step 4: Automatic calibration In order to make it easier to calibrate the mechanism, an automatic calibration function is designed, such as Figure 8 As shown, when the check weighing scale 44 and the recheck weighing scale 47 are calibrated, the electric lift 50 descends to place the check weighing calibration weight 45 and the recheck weighing calibration weight 46 on the weight support plate 53 for calibration. The check weighing calibration weight 45 and the recheck weighing calibration weight 46 are standard weights. This mechanism is designed with four symmetrically installed weights. After the calibration is completed, the electric lift 50 drags the check weighing calibration weight 45 and the recheck weighing calibration weight 46 to rise to complete the calibration work.

[0040] The finished product weighing check scale 44, re-check scale 47 and calibration mechanism are integrated in the weighing system bracket 51, which saves a lot of installation space for this production line. A small material disc vibrating feeder 6 function is designed for materials that cannot be cut or are flammable.

[0041] The batching device of the present invention has the following advantages: 1. Automatically array irregular block materials and array machines with pneumatic lifting, low mechanical noise and stable operation. 2. The conveyor evenly distributes the materials during transportation and corrects the irregular movement of materials, so that the materials can be weighed and measured more accurately. 3. The small material vibration feeding function is added to feed the materials evenly and make the batching weight more accurate. 4. The material selection function uses ten servo single-axis robots, which run smoothly, have low noise, low energy consumption, and accurate movement data. 5. The re-inspection weighing mechanism can verify the weight data of the checkweigher weighing mechanism, and truly achieve zero-error batching function.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.

The bulk material batching device according to claim 6, characterized in that: The finished material weighing mechanism (5) comprises a weighing system bracket (51), and the weighing system bracket (51) is provided with a check weighing scale (44), a weighing arc valve bin (52), a re-checking scale (47) and a material receiving port (48) in sequence from top to bottom.

8. The bulk material batching device according to claim 7, characterized in that: The weighing arc valve bin (52) is also provided with a bin door switch cylinder (54) and a synchronous gear (55), which are used to push the bin door of the weighing arc valve bin (52) to open for unloading and put the material into the re-inspection scale (47).

9. The bulk material batching device according to claim 8, characterized in that: The weighing system support (51) is also provided with an electric lift (50). When the check weighing scale (44) and the recheck weighing scale (47) need to be calibrated, the electric lift (50) descends to place the check weighing calibration weight (45) of the check weighing scale (44) and the recheck weighing calibration weight (46) of the recheck weighing scale (47) in a weight support plate (53) fixed on the weighing arc valve bin (52) for calibration. After the calibration is completed, the electric lift (50) drags the check weighing calibration weight (45) and the recheck weighing calibration weight (46) to rise, thereby completing the calibration work.

10. A batching method for a bulk material batching device for replenishing small materials, characterized in that: The steps include: Step 1: Slow feed screening a: The feeding mechanism feeds the block material into the step array machine (1), the material is stored in the silo and driven by the lifting component to lift the feeding step (12) to move up and down to feed and perform preliminary screening. The lifted material enters the conveyor (13), and the rejection component removes the high material for the first time. The rejected material returns to the silo, and the highly qualified material continues to move along the conveyor (13); b: Highly qualified materials enter the material correction mechanism (2). Materials with inconsistent directions are corrected for the first time during the conveying process by the correction reversing conveyor (22). The materials are corrected by the working principle that the correction conveyor (23) rotates forward and the correction reversing conveyor (22) rotates backward. If there is any missed material, it is corrected for the second time by the correction disc telescopic mechanism (24). The correction disc telescopic mechanism (24) has the function of breaking the arch. The corrected materials enter the over-conveyor (27); c: After the qualified materials are screened and enter the transition conveyor (27), the laser beam switches fixed on both sides of the transition conveyor (27) sense whether there are materials, and the materials are conveyed to the conveyor (13). After being weighed, the weight information of the materials is transmitted to the PLC for calculation, and then the materials enter the weighing buffer conveyor (31); d: Materials entering the weighing buffer conveyor (31) and those whose weight does not meet the standard after weighing are directly conveyed by the weighing buffer conveyor (31) to the checkweigher (44). Materials whose weight meets the standard are sequentially sent to the corresponding center position of the platform scale (34) through the weighing buffer cross-beam detection switch (33). The materials are transferred into the platform scale (34) by the material sorting robot (35) for data statistics and weight analysis and waiting for batching. Unqualified materials are conveyed to the finished product silo. After materials are stored in several platform scales (34), the second step of indiscriminate feeding is entered; Step 2: Indiscriminate feeding e: This step is the same as step a in the first step; f: Highly qualified materials enter the material correction mechanism (2), and the overall conveying speed is increased to 3 times that of the first step, and indiscriminate feeding is carried out. When the weight reaches the predetermined value range, the system enters the next finished product screening step; Step 3: Finished product screening g: At this time, the entire conveying system stops working. After the system automatically calculates, the small material disc vibrating feeder (6) will automatically start to replenish small materials until the weight reaches the total weight data of several stations matching the material finished product weighing mechanism (5). The weighing buffer mechanism (4) calculates the current weight, and the material sorting robot (35) pushes the material to the weighing buffer conveyor (31) according to the instructions received and transports it to the material finished product weighing mechanism (5); After the weight of the material on the check weighing scale (44) is qualified, the material in the weighing arc valve bin (52) is pushed by the synchronous gear (54) to open the control bin door for unloading, and the material is put into the receiving port (47). When the weight of the check weighing scale (44) is the same as that of the re-check weighing scale (47) or is within the allowable error range, the receiving port (47) puts the material into the receiving port (48) and falls into the finished product container (7), and is transported out through the finished product conveyor (8).
