All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, the present invention provides a linkage adjustment method for intelligent gypsum building material production lines, which not only synchronously and unidirectionally adjusts and controls the operating speeds of different sections of the same production line, but also further coordinately adjusts and controls the operating speeds of a plurality of production lines, so that all production lines can maintain the same speed for production, and even when the operating speeds are adjusted and controlled, all production lines are synchronously and unidirectionally adjusted to reduce or increase the operating speeds to improve the production efficiency, thereby enabling a plurality of production lines to realize joint control unified production.
The method specifically comprises the following steps:
100, setting a plurality of production lines, dividing each production line into a plurality of working sections according to a production flow, and creating a linkage adjustment mode of the same type of control objects of the plurality of production lines;
200, selecting one production line as an active regulation and control production line, using the rest production lines as passive regulation and control production lines, establishing a logic linkage system of a control object with the same property in all working sections of the active regulation and control production line, and introducing the logic linkage system into the passive regulation and control production line connected with a linkage adjustment mode;
300, respectively connecting all the sections in all the production lines with a PLC control system bus, selecting a production control object influencing the operation speed of the sections in each section of the active regulation production line, establishing a speed matching relational expression for regulating the operation speed of all the sections, and synchronously regulating the operation speed in the same direction by all the sections of the active regulation production line and the passive regulation production line by using a uniform speed matching relational expression;
step 400, creating a driving operation time matching relation after the operation speed of each section of all the production lines is adjusted, determining a new driving operation time point of each section after the operation speed is adjusted for the first time and an operation time interval corresponding to the current production speed, and determining a time point of next operation of each section according to the new driving operation time point and the operation time interval.
In step 100, the active regulation production line and the passive regulation production line form a parallel synchronous same-speed production mode in a linkage regulation mode, and each section of the passive regulation production line and the active regulation production line is connected with a PLC control system bus;
the same working sections of the active regulation production line and the passive regulation production line directly regulate and control production control objects by using a linkage regulation mode to synchronously modify the production control objects with the same amplitude so as to regulate and control the running speeds of all the production lines to be the same.
The PLC control system is used for dynamically regulating and controlling the number of production lines connected with the linkage adjustment mode and used for parallel production, regulating and controlling the production lines connected into the linkage adjustment mode by the PLC control system to change the running speeds of all the sections according to the same speed matching relation, and carrying out production work after regulating and controlling the running speeds;
the PLC control system closes the linkage adjustment mode of any production line to independently regulate and control the production line.
In step 200, the production line of the gypsum board is divided into a plurality of working sections from top to bottom, namely a feeding turning plate control working section, a film coating treatment working section, a film coating chasing shear control working section and a discharging turning plate working section, and the multidimensional control parameters of each working section are divided into an operation speed control object, a position control object and a pneumatic element control object;
the PLC control system respectively establishes logic linkage systems of all the working sections with respect to an operation speed control object, a position control object and a pneumatic element control object.
After any control object of any working section in each logic linkage system is adjusted, the same control objects in other working sections in the logic linkage system are synchronously and synchronously adjusted under logic control.
In order to conveniently regulate and control the running speeds of all production lines, namely the production speeds, the same working sections of all the production lines are subjected to associated regulation and control by using the linkage regulation and control mode, all the production lines use the same speed matching relational expression and the same driving running time matching relational expression, when all the production lines are subjected to associated regulation and control by using the linkage regulation and control mode, after the running speed of any working section of any one production line is selected and regulated, other production lines are synchronously regulated to the modified running speed, and other production lines regulate all the working sections to synchronously change the running speed according to the same speed matching relational expression and the same driving running time matching relational expression.
Therefore, in the embodiment, if the production speed of the production line needs to be changed, the running speed of any section of any production line is selected, and the synchronous and equidirectional uniform adjustment of all the production speeds can be realized, so that the gypsum building material production line of the embodiment adopts a top-down mode, the whole production line is decomposed into a plurality of sections according to modularization and systematization, different devices in each section are divided into control objects with different working properties, the control objects with the same working type of all the sections are independent and mutually connected, when the control object of one section is changed, the control objects with the same property in other sections are synchronously changed in the same direction, each section of other production lines keeps a uniform modification mode with the directly adjusted section, and all the control is realized by the data regulation and control of a PLC control system to regulate the running state of the control object of each section, the control mode logic is clear, the structure is simple, the operation is stable, and the efficiency is high.
In step 300, the operating speed of each station is changed in two ways, respectively:
regulating and controlling the operation speed of the workshop section on a human-computer interaction interface of a PLC control system, adjusting parameters of a production control object by the PLC control system according to a function model between the production control object and the workshop section operation speed, and changing the numerical value of the production control object of the corresponding workshop section by the PLC control system;
and regulating and controlling parameters of the production control object on a human-computer interaction interface of the PLC control system, and calculating the operation speed of the workshop section by the PLC control system according to a function model between the production control object and the workshop section operation speed.
The running speed of each working section is related to the corresponding speed control object, a stable control system of the gypsum board production line is formed, and a logic linkage system is established among the running speeds of all the working sections to ensure that the running speeds of all the working sections are synchronously and homodromously adjusted, so that the running speeds of other working sections do not need to be manually adjusted, and the whole system can still maintain a stable production flow after the running speed is adjusted.
On a human-computer interaction interface of the PLC control system, a production control object of each workshop section and the workshop section running speed of each workshop section form an independent module, a worker can adjust parameters of the production control object, determine the running speed of each workshop section according to a function model between the production control object and the workshop section running speed, or directly adjust the running speed, determine the parameters of the production control object according to the function model between the production control object and the workshop section running speed, and change the parameters of the production control object through the PLC control system.
In step 300, the specific implementation method for establishing the speed matching relation of the operating speeds of all the sections of the production line with the linkage adjustment mode is as follows:
determining the speed regulation amplitude of a working section for directly regulating the running speed on the active regulation production line, wherein the speed regulation amplitude is (V2-V1)/V1 when the working section A is changed from the original V1 to V2;
the PLC control system changes the operation speed of the same working section on the passive regulation production line with the linkage regulation mode according to the same speed regulation amplitude, and the synchronous regulation working section A is changed from the original V1 to V2, so that the speed regulation amplitude is (V2-V1)/V1;
the speed matching relation is used for indirectly adjusting according to the same speed regulation amplitude so as to synchronously and equidirectionally adjust the running speeds of other working sections, and the running speeds of the other working sections are adjusted to be V + V (V2-V1)/V1;
the PLC control system synchronously adjusts the running speed of all the working sections on the passive regulation production line with the linkage adjustment mode in the same direction according to the same speed matching relation, and the running speeds of other working sections are adjusted to V + V (V2-V1)/V1;
and adjusting a production control object of the conveying system according to the mapping relation between the working section running speed and the conveying speed of the conveying system so as to keep the fixed distance between the head and the tail of the two gypsum boards.
It is to be noted that the film covering treatment section and the film covering chasing and shearing control section both comprise a segmented conveying system, and the operation speed control objects comprise a feeding turning plate control section, a film covering treatment section, a film covering chasing and shearing control section, a discharging turning plate section and production control objects influencing the operation speed in the segmented conveying system;
the implementation method for adjusting the conveying speed of the segmented conveying system comprises the following steps:
establishing a mapping relation between the operating speed of the working section and the conveying speed of the corresponding segmented conveying system;
and on the premise of ensuring that the gypsum boards are conveyed and transferred according to the stable spacing, the conveying speed of the sectional conveying system is adjusted according to the mapping relation.
Therefore, the operation speed of each working section is linked, the mapping relation between the operation speed of the working sections and the segmented conveying speed is limited, and because the head-tail neutral position of the gypsum board cannot be too large and the adjacent boards cannot be collided during the operation of each working section, in order to ensure stable operation, the adjusted conveying speed of the segmented conveying system is determined according to the mapping relation between the operation speed of the working sections and the conveying speed of the segmented conveying system behind the working sections and the adjusted working section operation speed under the condition that the distance between different segmented conveying systems is fixed and unchanged under the general condition.
In step 400, the specific implementation steps of the driving operation time matching relation after the operation speed is adjusted in each section are as follows:
first, before the operation speed of each section is not adjusted, a time interval T1 is determined for each section to operate the gypsum board once at the original operation speed by the production control object.
When the running speed of each section is not adjusted, each section keeps the original running speed, at the moment, each section independently completes the operation on the gypsum board at a fixed time interval, for example, the feeding turning plate control section completes the feeding turning plate operation on the gypsum board at every interval t1, the film covering treatment section completes the feeding turning plate operation on the gypsum board at every interval t2, the film covering chasing and shearing control section completes the feeding turning plate operation on the gypsum board at every interval t3, and the discharging turning plate section completes the feeding turning plate operation on the gypsum board at every interval t 4.
And secondly, modifying the initial operation time point of the gypsum board for the initial operation of each section when the operation speed of each section is adjusted for the first time, and taking the operation time point as a new operation starting point.
And after the running speed of one working section is directly adjusted, the corresponding running speeds of other working sections are simultaneously and unidirectionally adjusted according to the speed matching relation, so that the whole production line of the gypsum board realizes dynamic balance at a new running speed.
After the operation speed of each section is adjusted for the first time, the specific implementation mode for determining the initial operation time point is as follows:
synchronously suspending the switches of the feeding turnover panel control working sections of all the production lines, and continuing working of the film coating treatment working section, the film coating chasing and shearing control working section and the blanking turnover panel working section until all gypsum boards on the segmented conveying system are completely treated;
and synchronously pausing the film covering treatment working sections, the film covering chasing and shearing control working sections, the blanking turnover plate working sections and the segmented conveying system of all the production lines, writing in the adjusted parameters of the production control object, starting all the working sections, and determining the initial operation time point of each working section.
And determining a new time interval T2 for each operation of the gypsum board after the operation speed of each section is adjusted, and adjusting the time point of the next operation of the production control object of each section according to the new time interval T2 for each section.
The specific implementation method for determining the new time interval T2 of each operation of the gypsum board after the adjustment of the running speed of each section is as follows:
the operation speeds of the film covering treatment working section and the film covering chasing and shearing control working section are combined, and the transportation speed adjusted by the segmented conveying system positioned above the rest working sections is combined, so that new time intervals T2 'and T2' of the corresponding working sections are independently determined;
