In order to make the technical solutions and advantages of the embodiments of the present application more apparent, the following further detailed description of the exemplary embodiments of the present application with reference to the accompanying drawings makes it clear that the described embodiments are only a part of the embodiments of the present application, and are not exhaustive of all embodiments. It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.
In the related art, when the distance between two rollers of a grinding machine is adjusted, an operator usually performs multiple times of debugging according to own experience and the type of a product to determine a proper target distance so as to ensure the production stability of the grinding machine after the machine testing. However, the roller spacing is often changed during operation of the grinding machine, and since the spacing between the rollers is often small, it is difficult for the operator's naked eye to detect the change in the roller spacing in a timely manner.
For example, the distance between the rollers may be gradually increased, and an operator cannot find the phenomenon that the distance between the rollers is increased in time, so that the problem of incomplete grinding is caused, and the quality of the soap is influenced; or the distance between the rollers may be gradually reduced, and the operator cannot find the reduction of the distance between the rollers in time, so that the speed of the grinder is restricted, the productivity is low, and the soap production efficiency is affected.
Moreover, since the operator usually carries out multiple times of adjustment according to own experience, the adjustment takes a long time, which is not favorable for the production efficiency of the soap and is difficult to ensure the processing racing speed. In addition, in the debugging process, an operator usually measures the distance between the rollers by a feeler gauge manually, and the accuracy of measurement is poor due to the problems of operation methods and the like, so that the method is time-consuming, is not favorable for the production efficiency of the soap, is difficult to ensure the processing precision and is not favorable for the quality of the soap.
In order to overcome at least one of the above problems, embodiments of the present application provide a method for controlling a roller spacing, a terminal device, a grinding machine, and a storage medium, where an actual spacing between rollers is obtained through the terminal device, an actual error of an actual spacing property with respect to a standard spacing is determined, and whether the actual error is within a preset error range is determined, so that the terminal device is favorable to find a situation that the actual error exceeds the preset error range in time, generate a grinding stopping instruction and send the grinding stopping instruction to the grinding machine, so that the grinding machine is in a grinding stopping state according to the grinding stopping instruction, and can adjust a gap between the rollers in time. So, too big or when the actual interval at the gyro wheel, terminal equipment can in time discover that the actual error surpasss predetermined error range to control to grind the machine and be in and stop grinding the state, adjust with the actual interval that can in time be to the gyro wheel, grind the machine and just can carry out the grinding operation at predetermined error range until the actual error of the actual interval of gyro wheel, thereby do benefit to the actual interval control that will grind the machine gyro wheel and at predetermined within range, do benefit to the quality of guaranteeing to wait to grind the product.

In other examples, the distance detection component may collect the distance between the rollers at intervals of a preset time period; wherein the preset time period can be set or selected by the operator himself. Correspondingly, the terminal equipment can acquire the distance acquired by the distance detection component at preset time intervals; the terminal equipment can determine the actual distance between the rollers according to the distance collected by the distance detection assembly.
Alternatively, as shown in fig. 2, step S101 includes:
s1011, acquiring the actual distance between the central axes of the two rollers acquired by the grinding machine; the actual distance is acquired through a distance detection assembly arranged on the central axis of the roller;
the terminal equipment can acquire the actual distance between two gyro wheel axis that distance detection subassembly can real-time detection. Or the terminal equipment can acquire the actual distance between the central axes of the two rollers at intervals of the preset time period from the distance detection assembly. The distance detection assembly can comprise a laser sensor and a reflecting piece, wherein the laser sensor and the reflecting piece can be respectively arranged on the two rollers and are respectively positioned on the central axes of the rollers so as to collect the actual distance between the central axes of the two rollers. Wherein, laser sensor and reflection part can set up respectively in the axis department of two gyro wheels through antifriction bearing to do benefit to and guarantee the accuracy nature that distance detection subassembly detected the result. The laser sensor can be in communication connection with the terminal device to transmit the detected actual distance to the terminal device.
S1012, obtaining a difference value between the actual distance and the radius of the two rollers, and determining the actual distance between the two rollers according to the difference value.
Illustratively, as shown in fig. 11, the terminal device may determine the actual spacing between the two scroll wheels 208 according to the following first formula:
Lpractice of＝DPractice of-R1-R2；
Wherein L isPractice ofRepresenting the actual spacing between the two rollers 208; dPractice ofRepresenting the actual distance between the two rollers 208; r1、R2Respectively, representing the radii of the two rollers 208.
With respect to the actual spacing LPractice ofAnd DPractice ofMay be stored in the terminal device in advance. Radius R of two rollers1、R2May be known data. Radius R of two rollers1、R2May be pre-stored in the terminal device, respectively. DPractice ofThe distance detection assembly collects and sends the distance detection assembly to the terminal equipment.
S102, determining an actual error according to the actual distance and a pre-acquired standard distance;
different products may have different standard pitches. In a specific implementation process, the matched standard spacing can be selected according to products. The standard spacing may be a known value stored in advance in the terminal device. Alternatively, the standard spacing may be obtained from a pre-stored functional relationship. After the standard pitch is acquired, the actual error of the actual pitch relative to the standard pitch may then be determined.
Alternatively, as shown in fig. 3, step S102 may include:
s1021, acquiring a difference value between the actual distance and a pre-acquired standard distance;
and S1022, acquiring the ratio of the difference value to the standard interval, and determining the actual error according to the ratio.
Illustratively, the actual error of the actual pitch with respect to the standard pitch may be determined according to the second formula:
Werror of the measurement＝(LPractice of-LStandard of merit)/LStandard of merit；
Wherein, WError of the measurementRepresenting the actual error; l isPractice ofRepresenting the actual spacing between the two rollers; l isStandard of meritRepresenting the actual spacing between the two rollers. L isPractice ofIs obtained in step S101; l isStandard of meritMay be pre-stored or pre-acquired for the terminal device.
In other implementations, the actual error may also be the difference between the actual spacing and the standard spacing; accordingly, the preset error range is also an allowable difference range.
S103, judging whether the actual error is within a preset error range;
after determining the actual error, the actual error may be compared to a preset error range to determine whether the actual error is within the preset error range. The preset error range can be a known value stored in the terminal equipment; illustratively, it may be a margin of error specified in the industry, such as ± 2%; the present example and the following examples are not exemplified by the example of a predetermined error range of ± 2%; it can be understood that: the preset error range is not limited thereto. Of course, different products may be provided with respective error ranges; in a specific implementation process, the matched error range can be selected according to products. The specific numerical value of the preset error range is not limited in this embodiment, and may be determined according to actual situations.
If the actual error is determined to be within the preset error range, the terminal device can generate a grinding instruction to be sent to the grinding machine in the debugging stage, so that the grinding machine can execute grinding operation according to the grinding instruction. For the grinder in the grinding stage, only the actual gap can be sent to the grinder for displaying, so that an operator can know the spacing condition of the rollers of the grinder in time; without sending grinding instructions to the grinder. Among these, it is understood that: the debugging stage is before the grinding stage, the debugging stage can be a stage for adjusting various parameters of the grinding machine, and the grinding stage can be a normal production stage.
And S104, if the actual error exceeds the preset error range, generating a grinding stopping instruction and sending the grinding stopping instruction to the grinding machine, so that the grinding machine is in a grinding stopping state according to the grinding stopping instruction, and the actual distance between the rollers can be adjusted.
During specific implementation, if the actual error is larger than the preset error range, that is, the actual error is larger than 2%, it is determined that the actual distance is too large, a grinding stopping instruction is generated, and the grinding stopping instruction is sent to the grinding machine, so that the grinding machine is in a grinding stopping state according to the grinding stopping instruction, the actual distance between the rollers can be adjusted, the actual distance between the rollers is reduced, and the actual error of the actual distance relative to the standard distance is within the preset error range.
If the actual error is smaller than the preset error range, namely the actual error is smaller than-2%, the actual distance can be determined to be too small, a grinding stopping instruction is generated and sent to the grinding machine, the grinding machine is in a grinding stopping state according to the grinding stopping instruction, the actual distance between the rollers can be adjusted, the actual distance between the rollers is increased, and the actual error of the actual distance relative to the standard distance is within the preset error range.
So, too big or when the actual interval at the gyro wheel, terminal equipment can in time discover that the actual error surpasss predetermined error range, and control and grind the machine and be in and stop grinding the state, adjust with the actual interval that can in time be to the gyro wheel, grind the machine and just can carry out the grinding operation at predetermined error range until the actual error of the actual interval of gyro wheel, thereby do benefit to the actual interval control that will grind the machine gyro wheel at predetermined within range, realized preventing slow-witted, can effectively prevent the not thorough scheduling quality problem of grinding that the too big gyro wheel interval leads to, and the lower scheduling problem of grinding efficiency that the gyro wheel interval undersize leads to. Wherein, the product to be ground can be soap.
The control method provided by the embodiment determines the actual error of the actual spacing to the standard spacing by acquiring the actual spacing between the rollers, and judges whether the actual error is within the preset error range, so that the condition that the actual error exceeds the preset error range can be found in time, a grinding stopping instruction is generated and sent to the grinding machine, and the grinding machine is in a grinding stopping state according to the grinding stopping instruction, so that the gap between the rollers can be adjusted in time. So, too big or when the actual interval at the gyro wheel, terminal equipment can in time discover that the actual error surpasss predetermined error range to control to grind the machine and be in and stop the grinding state, adjust with the actual interval that can in time be to the gyro wheel, grind the machine and just can carry out the grinding operation at predetermined error range until the actual error of the actual interval of gyro wheel, thereby do benefit to the actual interval control that will grind the machine gyro wheel and at predetermined within range, do benefit to the quality and the production efficiency of guaranteeing to wait to grind the product.
In one possible implementation, as shown in fig. 4, before determining the actual error according to the actual spacing and the pre-acquired standard spacing, the method may include: s100, acquiring a standard distance between two rollers in the grinding machine according to the characteristic information of the product to be ground.
Wherein the characteristic information of the product to be ground comprises at least one of the following: product name, product model.
In a specific implementation, as shown in fig. 5, step S100 may include:
s1001, receiving characteristic information of a product to be ground sent by a grinding machine;
the user can input or select the characteristic information of the product to be ground through the operation panel of the grinding machine; the grinder transmits the received characteristic information of the product to be ground input or selected by the user to the terminal equipment.
S1002, acquiring the matched maximum particle diameter and function coefficient according to the characteristic information;
the terminal equipment is pre-stored with the characteristic information, the maximum particle diameter and the functional relation of the product to be ground. When the terminal equipment receives the characteristic information, the matched maximum particle diameter and function coefficient can be searched from the pre-stored information according to the characteristic information. Wherein the maximum particle diameter and the functional relationship may be different for different products to be ground.
For different products to be ground, a plurality of groups of historical data can be respectively obtained, and the plurality of groups of historical data are compared and integrated, so that a functional relation and a functional coefficient in the functional relation between the maximum particle diameter and the standard gap are obtained. Wherein the historical data includes historical particle diameters and corresponding historical roller spacings. The functional relationship may be different for different products.
Illustratively, the functional relationship to be integrated according to the multiple sets of historical data may be:
Dmax＝k*Lstandard of merit；
Wherein D ismaxRepresents the maximum particle diameter; k represents a function coefficient; l isStandard of meritIndicating a standard spacing between the rollers. The functional relationship and the functional coefficient k may be the same for a particular product, such as a same class of products. Maximum particle diameter D for different products within the same category of productsmaxMay be the same or different. The method can be specifically set according to actual needs. The multiple sets of data can be compared and integrated by adopting common technical means in an industrial internet algorithm, and the embodiment is not particularly limited herein.
During specific implementation, corresponding function relational expressions and function coefficients can be obtained according to the obtained series corresponding to the product to be ground; the corresponding maximum particle diameter can be obtained according to the corresponding model of the product to be ground.
S1003, determining the standard distance between the two rollers according to the maximum particle diameter and the function coefficient.
Exemplarily, the standard distance can be obtained by substituting the obtained maximum particle diameter and the function coefficient into the function relation. For example, according to the functional relation, a quotient of the maximum particle diameter and the functional coefficient can be obtained, and the quotient is used as a standard distance between two rollers.
Of course, the implementation of this step is not limited thereto. For example, the standard gap of each product to be ground may be determined in advance from the functional relationship, the functional coefficient, and the maximum particle diameter and stored. In the specific implementation process, the matched standard gap can be directly found out according to the characteristic information of the product to be ground.
In this embodiment, it can be understood that: in the generation process of grinding the same product, the standard clearance can be obtained only in the initial debugging stage; it is not necessary to obtain a standard gap again in the subsequent grinding stage. Alternatively, the standard gap may be acquired only once upon receiving characteristic information of the product to be ground transmitted from the grinding machine.
In other examples, the grinder may receive a standard spacing value input by an operator, which the grinder sends to the terminal device. The terminal device may determine an actual error of the current spacing of the wheel according to the standard spacing and the actual spacing obtained in step S101, where the actual error is an error of the actual spacing obtained in step S101 with respect to the standard spacing.
In one possible implementation, after step S101, that is, after obtaining the actual spacing between the grinding mill rollers, the method further includes: the actual spacing is sent to the grinder so that the grinder can display the actual spacing.
The grinder may be provided with a display unit; the display unit is used for displaying the actual distance acquired by the terminal equipment. The display unit may comprise a display screen or a nixie tube, etc. For example, a display screen may be provided on the side of the grinding machine facing the operator, or a nixie tube may be provided at the operating panel of the grinding machine. The obtained actual distance is displayed, so that an operator can know the actual condition of the distance between the rollers according to the displayed actual distance; and in the process of adjusting the distance between the rollers, the adjusting condition can be conveniently known by the operator in time, so that the adjusting operation strategy is favorably adjusted, the adjusting efficiency of the operator is favorably improved, and the production efficiency is favorably improved. For example, when the difference between the actual pitch and the standard pitch is large, the amplitude or speed of turning the knob may be relatively large; when the difference between the actual pitch and the standard pitch is small, the amplitude or speed of turning the knob may be relatively small.
In addition, the standard gap corresponding to the product to be ground can be displayed on the display unit. That is, the display unit may display the standard gap acquired in advance by the terminal device. Through showing standard clearance, when the actual interval between operating personnel adjustment gyro wheel, standard clearance can regard as the reference value, does benefit to and improves operating personnel's adjustment efficiency, does benefit to and improves production efficiency.
In one possible implementation manner, the control method further includes:
and if the actual error exceeds the preset error range, generating prompt information and sending the prompt information to the grinding machine, so that the grinding machine can carry out sound prompt and/or visual prompt according to the prompt information.
Accordingly, the grinding machine may be provided with a reminder unit. Where the grinder is capable of emitting an audible cue, the cue unit may be an audio player. The prompting unit may be a display unit and/or an indicator light when the grinder is capable of giving a visual prompt. For example: when the actual error is determined to be beyond the preset error range, the terminal equipment generates prompt information and sends the prompt information to the grinding machine, an indicator lamp of the grinding machine can light up or flash according to the prompt information, and an audio player of the grinding machine, such as a buzzer, can make a sound according to the prompt information.
Through generating tip message and sending for grinding machine when confirming that actual error surpasss and predetermine error range for grind machine and carry out sound prompt and/or visual cue according to tip message, so, make operating personnel can in time know the gyro wheel interval unusual, also the gyro wheel interval is too big or undersize.
In one possible implementation manner, the control method further includes:
acquiring the actual rotating speed of a roller in the grinding machine in real time in the process of grinding operation of the grinding machine;
judging whether the actual rotating speed is within a preset rotating speed range or not;
and if the actual rotating speed is determined to exceed the preset rotating speed range, generating a rotating speed adjusting instruction and sending the rotating speed adjusting instruction to the grinding machine, so that the grinding machine can adjust the rotating speed of the rotating wheel according to the rotating speed adjusting instruction.
Wherein, the grinding machine is provided with a rotating speed sensor for acquiring the actual rotating speed of the roller; the speed sensor may be disposed on the roller or on a motor that drives the roller to rotate. And the rotating speed sensor is used for sending the acquired actual rotating speed to the terminal equipment. In addition, after the actual rotating speed of the roller is obtained, the actual rotating speed can be displayed on a display unit of the grinding machine, so that an operator can know the running condition of the roller conveniently.
Before determining whether the actual rotation speed is within the preset rotation speed range, the preset rotation speed may be obtained. The preset rotation speed may be a known value stored in the terminal device. The corresponding preset rotation speed can be different for different products. After the characteristic information of the product to be ground is received, the matched preset rotating speed can be searched according to the characteristic information. After the preset rotation speed is acquired, the preset rotation speed can also be displayed on a display unit of the grinding machine.
And according to the judgment result, if the actual rotating speed is determined to exceed the preset rotating speed range, generating a rotating speed adjusting instruction and sending the rotating speed adjusting instruction to the grinding machine, so that the grinding machine can adjust the rotating speed of the rotating wheel according to the rotating speed adjusting instruction until the actual rotating speed of the roller wheel reaches the preset range. The preset range can be a rotating speed range or an error range. And when confirming that actual rotational speed surpasss preset rotational speed scope, also can generate corresponding prompt message for the machine of grinding can send corresponding suggestion, so that operating personnel can in time know.
In this implementation, through the actual rotational speed that acquires the machine of grinding gyro wheel to surpassing predetermined rotational speed at actual rotational speed within range, steerable machine of grinding adjusts the rotational speed of gyro wheel, thereby, do benefit to the rotational speed that makes the machine of grinding gyro wheel and keep in predetermined within range, do benefit to the lower problem of productivity that avoids the rotational speed undersize to lead to.
