Preferred Embodiments of the Invention

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

As shown in Figure 1, the present invention provides a method for adjusting the linkage of an intelligent production line of gypsum building materials. This embodiment not only controls the running speeds of different sections of the same production line synchronously and in the same direction, but also further links the running speeds of multiple production lines. Control, so that all production lines maintain the same speed of production, even when adjusting the running speed, all the production lines are synchronously adjusted in the same direction to reduce or increase the running speed to improve production efficiency, thus enabling multiple production lines to achieve joint control of unified production, in In the same production workshop, the performance of gypsum boards produced in the same batch is the same, avoiding the problem of mismatching production speed caused by separate manual control of each production line and individual control of each section of each production line.

Specifically include the following steps:

Step 200, select one of the production lines as the active control production line, and the remaining production lines as the passive control production lines, establish a logical linkage system for the control object of the same nature in all sections of the active control production line, and import the logical linkage system into the passive control mode of the linkage adjustment mode. control the production line;

Step 400: Create a driving operation time matching relationship after adjusting the operating speed of each section of all production lines, determine the new driving operation time point of each section after the initial adjustment of the operating speed and the operating time interval corresponding to the current production speed, and use The new drive operation time point and operation time interval determine the time point for the next operation of each section.

In step 100, the active regulation production line and the passive regulation production line form a parallel synchronous and same-speed production mode under the linkage adjustment mode, and each section of the passive regulation production line and the active regulation production line is connected to the PLC control system bus;

Between the same section of the active control production line and the passive control production line, the linkage adjustment mode is used to directly control the production control objects to be synchronously modified at the same amplitude, so as to control the running speed of all production lines to be the same.

The PLC control system is used to dynamically control the number of production lines connected to the linkage adjustment mode in parallel production, and the PLC control system controls the production lines connected to the linkage adjustment mode to change the running speeds of all sections according to the same speed matching relationship, and after adjusting the running speed carry out production work;

The PLC control system closes the linkage adjustment mode of any production line to independently control the production line.

In step 200, the gypsum board production line is divided into a plurality of sections from top to bottom, which are the control section for feeding and turning plate, the section for laminating treatment, the section for controlling the shearing of film and the section for cutting and turning plate, and each section is The multi-dimensional control parameters are divided into operation speed control objects, position control objects and pneumatic components control objects;

The PLC control system establishes the logical linkage system of the operating speed control objects, position control objects and pneumatic components control objects in all sections respectively.

After any control object in any section in each logical linkage system is adjusted, the same control objects in other sections in the logical linkage system are adjusted synchronously in the same direction under logical control.

In this embodiment, in order to facilitate the regulation of the running speed of all production lines, that is, the production speed, the same section of all production lines is regulated by the linkage adjustment mode, so that all production lines use the same speed matching relationship and driving operation time matching relationship. When all the production lines use the linkage control mode for associated control, when the running speed of any section of any production line is selected and adjusted, the other production lines will be adjusted to the modified running speed synchronously, and the other production lines will follow the same The speed matching relationship and the driving operating time matching relationship adjust all sections to synchronize the same change of running speed.

Therefore, in this embodiment, if the production speed of the production line needs to be changed, the running speed of any section of any production line can be selected to realize the unified adjustment of the production speed of all productions in the same direction. The building material production line adopts a top-down method, and the entire production line is decomposed into several sections according to modularization and systematization. Both independent and interconnected, when the control object of one section is changed, the control objects of the same nature in other sections are changed synchronously and in the same direction, and each section of other production lines maintains the same modification method as the directly adjusted section, and all controls are It is realized by the data of the PLC control system regulating the operation status of the control object of each section, which makes the control method clear in logic, simple in structure, stable in operation and high in efficiency.

In step 300, there are two ways to change the running speed of each section, which are:

The operation speed of the section is regulated on the human-computer interaction interface of the PLC control system. The PLC control system adjusts the parameters of the production control object according to the function model between the production control object and the operation speed of the section, and the PLC control system changes the value of the production control object of the corresponding section;

The parameters of the production control object are regulated in the human-computer interaction interface of the PLC control system, and the PLC control system calculates the operation speed of the section according to the function model between the production control object and the operation speed of the section.

The running speed of each section is related to the corresponding speed control object, and forms a stable control system for a gypsum board production line. A logical linkage system is established between the running speeds of all sections to ensure that the running speeds of all sections are synchronously adjusted in the same direction. Therefore, there is no need to manually adjust the running speed of other sections, so that the entire system can still maintain a stable production process after adjusting the running speed.

On the human-computer interaction interface of the PLC control system, the production control object of each section and the section running speed of each section form an independent module, and the staff can adjust the parameters of the production control object, according to the production control object and the section running speed. Determine the running speed of each section by using the function model between them, 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 running speed of the section, and change the production control object through the PLC control system parameter.

In step 300, the specific implementation method of establishing the speed matching relational expression of the running speeds of all the sections of the production line with the linkage adjustment mode is:

Determine the speed control range of the section that directly adjusts the running speed of the active control production line. Section A is changed from the original V1 to V2, and the speed control range is specifically (V2-V1)/V1;

The PLC control system changes the running speed of the same section of the passive control production line with the linkage adjustment mode according to the same speed control range, and the synchronous adjustment section A is changed from the original V1 to V2, then the speed control range is (V2-V1)/V1 ;

The speed matching relationship is used for indirect adjustment according to the same speed regulation range to synchronously adjust the running speed of other sections in the same direction, and the running speed of other sections is adjusted to V+V*(V2-V1)/V1;

The PLC control system adjusts the running speed synchronously and in the same direction for all sections of the passive control production line with the linkage adjustment mode according to the same speed matching relationship, and the running speed of other sections is adjusted to V+V*(V2-V1)/V1;

It should be added that both the lamination processing section and the lamination cutting control section include a segmented conveying system, and the operation speed control objects include the feeding flap control section, lamination processing section, lamination running shear control section, The production control objects that affect the running speed in the blanking and flapping section and the sectional conveying system;

The realization method of adjusting the conveying speed of the sectional conveying system is as follows:

Establish the mapping relationship between the running speed of the section and the conveying speed of the corresponding segmented conveying system;

On the premise of ensuring that the gypsum board is transported and transferred at a stable distance, adjust the conveying speed of the segmented conveying system according to the mapping relationship.

Therefore, this embodiment not only links the operation speed of each section, but also defines the mapping relationship between the operation speed of the section and the conveying speed of sections. Since each section is working, the head and tail of the gypsum board are required to be in the neutral position. If it is too large, it will not be able to collide with adjacent boards. Therefore, in order to ensure stable operation, in general, when the distance between different section conveying systems is fixed, the running speed of the gypsum board passing through the section is different from that of the section located behind the section. The mapping relationship between the conveying speeds of the section conveying system and the adjusted operating speed of the section are used to determine the adjusted conveying speed of the section conveying system.

In step 400, the specific implementation steps of the driving operation time matching relational expression after adjusting the operation speed of each working section are as follows:

① Before adjusting the running speed of each section, determine the time interval T1 for each operation of the gypsum board by the production control object at the original running speed of each section.

When the running speed of each section is not adjusted, each section maintains the original running speed. At this time, each section independently completes an operation on the gypsum board at a fixed time interval. The feeding and turning operation of gypsum board is completed at interval t1, the feeding and turning operation of gypsum board is completed at every interval t2 in the coating treatment section, and the feeding and turning operation on gypsum board is completed at every interval t3 in the film-covering and shearing control section. , the feeding and turning operation of the gypsum board is completed every t4 in the blanking and turning section.

② When adjusting the running speed for the first time in each section, modify the initial running time point of the first operation of the gypsum board in each section, and use this running time point as the new running starting point.

When the running speed of one section is directly adjusted, other sections adjust the corresponding running speeds in the same direction at the same time according to the speed matching relationship, so that the entire gypsum board production line can achieve dynamic balance at the new running speed.

Among them, after the initial adjustment of the running speed of each section, the specific implementation method of determining the initial running time point is as follows:

Simultaneously suspend the switch of the feeding flap control section of all production lines, and continue to work in the lamination processing section, the lamination chase shear control section and the unloading flap section until all the gypsum boards on the sectional conveying system are completely processed;

Simultaneously suspend the lamination processing section, lamination trimming control section, blanking plate section and section conveying system of all production lines, write the adjusted parameters of the production control object and start all sections, and determine the initial running time of each section point.

③ Determine the new time interval T2 for each operation of the gypsum board after each section adjusts the running speed, and each section adjusts the time point of the next operation of the production control object of each section according to the new time interval T2.

Wherein, the specific implementation method of determining the new time interval T2 for each operation of the gypsum board after adjusting the operating speed of each section is:

Combined with the running speed of the lamination processing section and the lamination cutting control section, as well as the adjusted transport speed of the segmented conveying system located above the remaining sections, the new time intervals T2' and T2" for the corresponding sections are separately determined;

Among them, there is a functional relationship between the new time interval T2' and the running speed of the lamination processing section and the adjusted transportation speed of the corresponding segmented conveying system. There is a functional relationship between the adjusted transport speeds of the sectional conveyor system.

Therefore, in this embodiment, after adjusting the running speed of a certain section of a certain production line, the bus control is used to regulate the running speed of other sections, and according to the function model between the running speed of each section and the parameters of the production control object, the operation speed of the section is determined. The parameter adjustment of the production control object, and the servo control is used to change the operation mode of the production control object. Therefore, in this embodiment, the bus control and servo control are combined, and each device in each section is connected with the PLC through the bus control method The control system is connected, and with the high-precision position control characteristics of the servo, the labor cost is greatly reduced, the instability of manual adjustment of mechanical equipment in the production process is reduced, and the production stability and product qualification rate are improved.

In addition, while adjusting the running speed of a certain section of a production line, the PLC control system is used to control the same section of other production lines connected to the linkage adjustment mode to adjust the running speed synchronously, and all sections of other production lines adjust all sections according to the same control method. The operation speed of the workshops can be changed synchronously and in the same direction, so that multiple production lines can realize the unified production of joint control. In the same production workshop, the performance of the gypsum board produced in the same batch is the same, avoiding the separate manual control of each production line, and The individual regulation of each section of each production line creates the problem of mismatched production speeds.
