It should be apparent that the described embodiments are only a few embodiments of the present application, and not all embodiments of the present application, and it should be understood that the present application is not limited to the example embodiments described herein.

Summary of the application

At present, many products are obtained by combining and stirring various materials, for example, products produced by cement mixing plants are obtained by combining and stirring various materials. The materials are usually conveyed to a waiting hopper by a belt or the like, and then put into a stirring or combining device for stirring or combining, so as to obtain the final product. However, the required transportation time is different due to the different distances between each material and the waiting hopper, so that the loading time cannot be accurately known, and the time for the waiting hopper to start to unload materials to the stirring equipment after the transportation of the materials is finished is also difficult to grasp. If the unloading time is too long, the unloading waiting time is too long, and the production efficiency is reduced.

In order to solve the problem of low production efficiency, the application provides a material conveying method, a material conveying device and a mixing station, the material loading sequence of various materials and the time for starting material loading of each material are adjusted by calculating the material loading time of each material and considering the state information (including whether the material is completely unloaded, the residual material unloading amount and the like) of a material waiting hopper, so that the waiting time between the material unloading completion of the material waiting hopper and the material loading is reduced as much as possible, and the material conveying efficiency and the production efficiency are improved.

After receiving an order (including the type, weight and the like of a target material), the mixing station can determine the type and the corresponding weight of initial materials required for producing the target material according to the order, then the initial materials with the corresponding weight are transmitted to the belt by the material bin 1 corresponding to the initial materials, after all the initial materials are transmitted into the material waiting bin 3 by the belt, the material waiting bin 3 starts to unload again so as to unload all the initial materials into the mixing main machine 2 for mixing to obtain a final product (such as concrete and the like), and after the material waiting bin 3 finishes unloading, the initial materials of the next order or the next order can be transmitted into the material waiting bin 3.

In an embodiment, the mixing plant in the application can further include a to-be-charged hopper weighing device, the to-be-charged hopper weighing device is arranged at the to-be-charged hopper 3 and is in communication connection with the controller, and the to-be-charged hopper weighing device is used for collecting the weight of the materials in the to-be-charged hopper 3 and sending the weight information of the materials in the to-be-charged hopper 3 to the controller, so that the controller can accurately control the discharging operation of the to-be-charged hopper 3.

Exemplary method

Fig. 2 is a schematic flow chart of a material conveying method according to an exemplary embodiment of the present application. As shown in fig. 2, the material conveying method is applied to the controller in the mixing station, and the material conveying method comprises the following steps:

step 210: determining the types and the weights of various initial materials according to the target materials; wherein the target material is obtained by combining a plurality of initial materials.

After a customer places an order, according to the requirements of target materials (or products) in the customer's order, the types and weights of various initial materials are determined, for example, the order contains the formula and proportion of the target materials or the requirements of indexes, and the types and corresponding weights of the initial materials required for producing the target materials can be obtained according to the formula, proportion or the requirements of indexes (the obtaining mode can be obtained by looking up a table according to the original formula), that is, the target materials in the order information are split into various initial materials actually required in production, for example, aggregates (including stones, sands, and the like).

Step 220: calculating the feeding time of each initial material according to the type and weight of each initial material; the feeding time represents the time of all the initial materials from the material bin to the material waiting bin.

After the types and the weights of the multiple initial materials required by the target material are obtained, the feeding time of each initial material from the material bin to the material waiting hopper is calculated respectively, namely the total time required by each required initial material to be conveyed to the material waiting hopper is calculated.

Step 230: and determining the feeding sequence and the feeding starting moment of the various initial materials according to the feeding time of the various initial materials and the state information of the material waiting hopper.

After the required feeding time of each initial material is obtained through calculation, the required feeding sequence and the feeding starting time of the initial materials are determined by combining the current state information of the material waiting hopper, so that the shortest waiting time of the empty hopper of the material waiting hopper and the shortest whole feeding time are ensured, the material conveying efficiency is improved, the short storage time of all the initial materials in the material waiting hopper is also ensured, and the adhesion of the materials is avoided; and the starting feeding moment represents a moment point when the initial material is unloaded from the corresponding material bin. Meanwhile, the feeding completion time can be accurately obtained according to the determined feeding starting time and the feeding time, so that seamless connection between initial material feeding and waiting hopper discharging is realized. In the embodiment of the application, the scales at the material bins of each initial material can be used for metering to obtain the initial materials with required weight, and the hopper scales can be arranged at the positions of the waiting hoppers to know the total weight of the initial materials in the waiting hoppers in real time, so that the unloading state (including the residual amount and the like) of the initial materials in the waiting hoppers can be determined, the weight of the initial materials can be verified, and the problem that the produced products are poor due to the scale faults at the positions of single material bins is avoided.

In an embodiment, the specific implementation manner of step 230 may be: judging whether the state information of the hopper to be charged meets a preset condition, wherein the preset condition can be that the weight of materials in the hopper to be charged is smaller; if the weight of the materials in the hopper to be charged is smaller than the preset weight (which indicates that the residual discharging time of the materials in the hopper to be charged is smaller than a preset time), determining the charging sequence and the charging starting moment of the various initial materials according to the charging time of the various initial materials and the state information of the hopper to be charged, and carrying out material conveying of the various initial materials according to the charging sequence and the charging starting moment of the various initial materials. That is to say, when the weight of the material in the waiting hopper is small (the corresponding unloading time is less than the time for conveying the material in the next round from the material bin to the waiting hopper), the next round of loading operation can be started at this time, so as to reduce the waiting time of the waiting hopper as much as possible, thereby improving the efficiency.

According to the material conveying method, the types and the weights of various initial materials of the target material are determined according to the target material, then the corresponding feeding time from a material bin to a material waiting hopper is calculated according to the type and the weight of each initial material, and finally the feeding sequence and the feeding starting time of the initial materials are determined according to the feeding time of the initial materials and the state information of the material waiting hopper; the required initial material type and weight are determined according to the target material information, then the feeding time of each initial material is calculated, the state information of the waiting hopper is combined, the optimal feeding sequence and the feeding starting time are determined, the waiting time of the waiting hopper is reduced or avoided, the total feeding time of the waiting hopper can be accurately controlled, the discharging time of the waiting hopper can be accurately set, the waiting and incomplete discharging are avoided, the situation that materials in the waiting hopper are stored for a long time and are adhered to the waiting hopper can be avoided, and the material conveying efficiency can be improved.

Fig. 3 is a schematic flowchart of a method for calculating an initial material loading time according to an exemplary embodiment of the present application. As shown in fig. 3, the step 220 may include:

step 221: and acquiring the transmission distance between a material bin for storing the initial materials and the material waiting hopper according to the types of the initial materials.

Usually, the material bins are all arranged along the extension direction of the flat belt, namely, the transmission distance between each material bin and the material waiting hopper is different, and the transmission time of each initial material after being unloaded from the material bins onto the flat belt is different. Therefore, the transmission distance between the corresponding material bin and the material waiting hopper is determined according to the type of the required initial materials, so that the transmission time of the initial materials transmitted to the material waiting hopper through the belt is obtained.

Step 222: and calculating the loading time of the initial materials according to the transmission distance and the transmission speed, the unloading speed of the material bin and the weight of the initial materials.

After the transmission distance between the material bin for storing the initial materials and the material waiting hopper is obtained, the transmission time of the initial materials transmitted from the belt at the material bin to the material waiting hopper can be calculated by combining the transmission speed of the belt. However, the discharging process of the material bin is not completed instantaneously, and the initial material is usually discharged to the belt through the discharge opening of the material bin at a certain discharging speed, and the discharging time of the initial material can be calculated according to the required weight of the initial material and the discharging speed of the corresponding material bin. And (3) starting to unload from the material bin until the corresponding initial material completely reaches the total time of the material waiting hopper, namely the loading time = the transmission time of the flat belt + the transmission time of the inclined belt + the unloading time. The feeding time of each initial material can be calculated respectively according to the mode.

Fig. 4 is a flowchart illustrating a method for determining a loading strategy according to an exemplary embodiment of the present application. The state information of the material waiting hopper comprises the weight information of the materials in the material waiting hopper and the discharging speed of the material waiting hopper; as shown in fig. 4, the step 230 may include:

step 231: and calculating the residual unloading time of the hopper to be unloaded according to the weight information of the materials in the hopper to be unloaded and the unloading speed of the hopper to be unloaded.

The method comprises the following steps that a hopper scale or other weight/weighing sensors are arranged at a position of a hopper to be weighed so as to obtain the weight of initial materials in the hopper in real time, specifically, after the hopper scale is calibrated, namely the weight displayed on the hopper scale is the weight of the initial materials, the weight displayed on the hopper scale can be obtained according to the current weight displayed on the hopper scale; when the bucket scale is not calibrated, the weight displayed on the bucket scale is the weight of the initial material and the weight of the to-be-charged hopper body, and at the moment, the weight of the initial material can be obtained by subtracting the weight of the to-be-charged hopper body in an empty hopper state from the weight displayed on the current bucket scale, so that the total weight of the material in the to-be-charged hopper can be obtained in real time. According to the total weight of the materials in the to-be-charged hopper and the discharging speed of the to-be-charged hopper, the residual discharging time of the to-be-charged hopper can be calculated, and therefore the discharging starting time and the discharging ending time of the to-be-charged hopper can be accurately controlled.

Step 232: and determining the loading sequence and the loading starting moment of the various initial materials according to the residual unloading time and the loading time of the various initial materials.

After the remaining unloading time of the material waiting hopper is obtained, the loading time of multiple initial materials of the next batch (taking the materials in the material waiting hopper as the current batch) is combined, and the loading sequence of the multiple initial materials and the starting loading time of each initial material are reasonably arranged. The feeding strategy of the initial materials of the next batch is reasonably arranged according to the remaining discharging time of the material waiting hopper, so that seamless connection is realized, the production efficiency is improved, and the production period is shortened.

In an embodiment, a specific implementation manner of the step 232 may be: and selecting the initial material with the loading time greater than or equal to the residual unloading time and the minimum difference with the residual unloading time as the first material in the loading sequence. When the loading sequence of the initial materials is arranged, the initial materials with the loading time slightly longer than or equal to the remaining unloading time of the material waiting hopper can be preferentially considered as the first loaded initial materials, so that seamless connection between the unloading of the material waiting hopper and the loading of the initial materials is realized, and the production period is shortened. In a further embodiment, the feeding sequence of the initial materials can be arranged according to the principle that the transmission distance between the material bins of the initial materials and the material waiting hopper is from small to large, so that the total feeding time is shortened by utilizing the distance difference between the material bins of the initial materials which are fed successively, namely, the material bins far away from the material waiting hopper can be opened to discharge when the discharging of the material bins close to the material waiting hopper is not finished, and the feeding period is fully shortened.

In one embodiment, the step 232 may include: and determining the starting feeding moment of the first initial material in the feeding sequence according to the remaining discharging time. After determining the type of the first initial material in the loading sequence, determining the loading start time of the first initial material according to the remaining unloading time, for example, if the remaining unloading time is 10 seconds, and the transmission time of the first initial material is greater than or equal to 10 seconds, the current time may be used as the loading start time of the first initial material.

In a further embodiment, the step 232 may include: and determining the starting feeding moment of the subsequent initial materials of the current initial materials according to the feeding time of the current initial materials in the feeding sequence. After the feeding time of the current initial material in the feeding sequence is known, the end time of the current initial material feeding is known, and the end time can be selected as the starting feeding time of the subsequent initial material. Of course, in order to further shorten the feeding period, the time for the subsequent initial material to be transmitted from the material bin to the corresponding position of the material bin of the current initial material can be calculated by combining the transmission distance between the material bin of the subsequent initial material and the material bin of the current initial material, and the feeding operation of the subsequent initial material can be started by extracting the time on the basis of the end time of the feeding of the current initial material, so that the seamless connection of the feeding is realized.

Fig. 5 is a flowchart illustrating a method for determining a loading start time according to an exemplary embodiment of the present application. As shown in fig. 5, the method may specifically include the following steps:

step 510: when a first distance between the material bin of the current initial material and the material waiting hopper is smaller than a second distance between the material bin of the subsequent initial material of the current initial material and the material waiting hopper, acquiring a distance between the material bin of the current initial material and the material bin of the subsequent initial material of the current initial material along the material transmission direction.

If the first distance between the material bin of the current initial material and the material waiting hopper is smaller than the second distance between the material bin of the subsequent initial material of the current initial material and the material waiting hopper, the material bin of the current initial material is closer to the material waiting hopper than the material bin of the subsequent initial material. At the moment, the distance between the material bin of the current initial material and the material bin of the subsequent initial material of the current initial material along the material transmission direction can be obtained, so that the time that the subsequent initial material can be loaded in advance is determined.

Step 520: and calculating the time difference of the subsequent initial materials of the current initial materials from the position of the material conveying device corresponding to the material bin of the subsequent initial materials of the current initial materials to the position of the material conveying device corresponding to the material bin of the current initial materials according to the distance of the material bins and the transmission speed.

After the distance of the material bin is obtained, the time difference of the subsequent initial material from the position of the material conveying device corresponding to the material bin (namely, the position corresponding to the material bin on the flat belt) to the position of the material conveying device corresponding to the material bin of the current initial material (namely, the position corresponding to the material bin on the flat belt) is calculated by combining the transmission speed, and the time for the subsequent initial material to be fed in advance before the feeding of the current initial material is finished is obtained.

Step 530: and determining the starting feeding time of the subsequent initial materials of the current initial materials according to the time difference of the material bins and the feeding time of the current initial materials.

And according to the material bin time difference and the material loading ending time of the current initial material, determining that the material loading starting time of the subsequent initial material is equal to the material loading ending time of the current initial material minus the material bin time difference. For example, when a first distance between the material bin of the current initial material and the material waiting hopper is smaller than a second distance between the material bin of the subsequent initial material of the current initial material and the material waiting hopper, the subsequent initial material loading time = current initial material loading time + current initial material unloading time — material bin time difference (i.e., inter-material bin distance/transfer speed). It should be understood that, because all the initial materials are mixed in the material waiting bin by the feeding, the embodiment of the present application may also adopt stacking conveying, that is, the material bin corresponding to the current initial material and the material bin corresponding to the subsequent initial material are simultaneously discharged, and the distance between the material bin corresponding to the current initial material and the material waiting bin is smaller than the distance between the material bin corresponding to the current initial material and the material waiting bin, and the other material bins lag behind a specific time and start discharging, where the specific time is at least longer than the time for the belt to run from the material bin corresponding to the current initial material to the material bin.

Fig. 6 is a schematic flowchart of a method for determining a loading start time according to another exemplary embodiment of the present application. As shown in fig. 6, the method may specifically include the following steps:

step 610: when a first distance between a material bin of a current initial material and a material waiting hopper is larger than a second distance between a material bin of a subsequent initial material of the current initial material and the material waiting hopper, the distance between the material bin of the current initial material and the material bin of the subsequent initial material of the current initial material along the material transmission direction is obtained.

If the first distance between the material bin of the current initial material and the material waiting hopper is larger than the second distance between the material bin of the subsequent initial material of the current initial material and the material waiting hopper, the material bin of the current initial material is far away from the material waiting hopper relative to the material bin of the subsequent initial material. At this time, the distance between the material bin of the current initial material and the material bin of the subsequent initial material of the current initial material along the material transmission direction can be obtained, so as to determine the time for the subsequent initial material to be loaded.

Step 620: and calculating the time difference between the subsequent initial material of the current initial material and the material conveyer corresponding to the material bin of the current initial material from the position of the material conveyer corresponding to the material bin of the subsequent initial material of the current initial material to the position of the material conveyer corresponding to the material bin of the current initial material according to the distance and the transmission speed of the material bins.

After the distance of the material bin is obtained, the time difference of the subsequent initial materials from the position of the material conveying device corresponding to the material bin (namely, the position corresponding to the material bin on the flat belt) to the position of the material conveying device corresponding to the material bin of the current initial materials (namely, the position corresponding to the material bin on the flat belt) is calculated by combining the transmission speed, and the time for the subsequent initial materials to be loaded after the current initial materials are loaded is obtained.

Step 630: and determining the starting feeding time of the subsequent initial materials of the current initial materials according to the time difference of the material bins and the feeding time of the current initial materials.

And according to the time difference of the material bin and the feeding ending time of the current initial material, determining that the feeding starting time of the subsequent initial material is equal to the feeding ending time of the current initial material plus the time difference of the material bin. For example, when a first distance between the material bin of the current initial material and the material waiting hopper is greater than a second distance between the material bin of the subsequent initial material of the current initial material and the material waiting hopper, the subsequent initial material loading time = the current initial material loading time + the current initial material unloading time + the material bin time difference (i.e., the distance between the material bins/the transmission speed).

Fig. 7 is a schematic flow chart of a material conveying method according to another exemplary embodiment of the present application. As shown in fig. 7, the material conveying method may further include:

step 240: and executing the opening or closing operation of the discharge door of the waiting hopper according to the state information of the waiting hopper and the required weight of the target material.

When the weight of the materials in the to-be-charged hopper reaches the required weight of the target materials and the bin gate of the to-be-charged hopper is in a closed state, the bin gate of the to-be-charged hopper can be opened so that the materials in the to-be-charged hopper are discharged into the stirring main machine for stirring operation. Of course, the bin door of the waiting hopper can also be opened when the weight of the material in the waiting hopper reaches a certain proportion (for example, 80%) of the required weight of the target material and the bin door of the waiting hopper is in a closed state, so that the loading operation and the unloading operation of the waiting hopper are performed synchronously, and the unloading time of the waiting hopper is reduced. When the weight of the material in the material waiting hopper is smaller than a preset value (for example, a fixed value of 0 or close to 0) and the bin gate of the material waiting hopper is in an open state, the bin gate of the material waiting hopper can be closed to ensure that the next batch of material is fed into the material waiting hopper.
