Description

Technical Field

[0001] This invention relates to the field of industrial control system technology, and in particular to a control system and production method for a fully automated calcium silicate board coating and laminating production line. Background Technology

[0002] Calcium silicate composite boards are widely used in building walls and ceilings due to their fire-resistant, heat-insulating, lightweight, and high-strength properties. Their production process involves multiple steps, including adhesive application, rock wool lamination, base plate lamination, and cold-press curing. Traditional production lines often employ manual or semi-automated control, resulting in the following technical drawbacks: The equipment in each process operates independently, lacking coordinated control, resulting in mismatched production rhythms, easy accumulation of boards or waiting times, and low production efficiency. The glue application process relies on manual experience to adjust the glue supply, leading to frequent problems such as uneven glue application, excessive or insufficient glue, resulting in unstable bonding strength of the composite board and a high defect rate. The pressing parameters of the rock wool composite and the base plate are fixed and cannot be adaptively adjusted according to the board specifications, resulting in poor thickness consistency of the composite board. The lack of full-process sensing detection and closed-loop feedback means that abnormal situations in the production process cannot be warned in time, requiring manual inspection and troubleshooting, which increases labor costs. Summary of the Invention

[0003] This invention aims to solve the technical problems of existing calcium silicate board coating and laminating production lines, such as the lack of coordinated control due to independent operation of each piece of equipment, the reliance on manual adjustment of adhesive supply leading to unstable bonding strength, the inability to adaptively adjust laminating parameters resulting in poor consistency of composite board thickness, and the lack of full-process sensing detection and feedback. The invention provides a fully automated control system and production method for a calcium silicate board coating and laminating production line, with the specific technical solution as follows: The fully automated calcium silicate board coating and laminating production line control system and production method include: a central control unit, which is a PLC programmable logic controller or industrial computer, with a built-in full-process parameter linkage control model, used to receive board specifications and process parameter instructions, and dynamically issue collaborative control instructions based on sensor detection feedback signals; the feeding and conveying control module is circuitically connected to the feeding and conveying table, and collects the board conveying position signal through the board arrival sensor to drive the conveying table to achieve precise control of start, stop and speed, and establishes action interlock logic with the gantry feeding control module to avoid feeding misalignment; the gantry feeding control module is circuitically connected to the gantry feeding machine, integrating... Visual positioning and displacement sensors, through visual recognition algorithms, calibrate the corner positions of the calcium silicate panel, controlling the gripping, lifting, and translational movements of the mechanical claw to ensure the panel gripping and positioning error is less than 0.3mm. The first glue application control subsystem includes a glue application execution module and a glue supply adjustment module. The glue application execution module is connected to the first fully automatic glue application machine, and the glue supply adjustment module is connected to the glue supply system of the first fully automatic glue application machine. The glue supply adjustment module is equipped with a flow sensor and a pressure sensor, establishing an adaptive mapping relationship between glue application parameters and panel thickness. Based on real-time detection data from the panel thickness sensor, it dynamically adjusts the glue supply flow rate and glue application pressure, adjusting according to the mapping relationship. The nozzle height and moving speed are controlled to ensure that the glue application uniformity error is less than 3%. The rapid conveying control module is connected to the rapid conveying platform via circuit design, collects real-time production cycle data of the preceding and following processes, and adjusts the conveying speed through a cycle difference compensation algorithm to ensure that the cycle difference between adjacent processes is ≤5s, achieving seamless transfer of boards. The rock wool composite control module is connected to the rock wool placement machine and the automatic rock wool composite machine via circuit design, integrates a thickness detection sensor, and controls the laying speed and laying width of the placement machine according to preset rock wool thickness parameters. At the same time, it dynamically matches the pressing force and pressing speed of the composite machine, forming a closed-loop adjustment from rock wool thickness to pressing parameters to ensure the composite layer thickness is accurate. The difference is less than 0.2mm; the second glue application control subsystem has the same structure as the first glue application control subsystem. The second glue application control subsystem includes a glue application execution module connected to the second fully automatic glue application machine and a glue supply adjustment module connected to the glue supply system of the second fully automatic glue application machine. The glue supply adjustment module independently adjusts the glue application parameters according to the bonding strength requirements of the base plate composite, forming a differentiated glue application control logic with the first glue application control subsystem; the positioning control module is connected to the circuit design of the four-sided positioning machine of the board, integrates a visual inspection sensor and a servo drive unit, and controls the extension stroke and positioning force of the positioning claw through the edge recognition algorithm to achieve a four-sided positioning error of ≤0.5mm; The base plate composite control module is connected to the circuit design of the base plate composite machine. Based on the total thickness of the board and the composite layer distribution parameters, it adaptively adjusts the pressing pressure and pressing time to avoid over-pressure causing board deformation or under-pressure causing bonding failure. The palletizing and transfer control module is connected to the circuit design of the gantry palletizer and the lifting transverse conveyor, integrating a weight sensor. Based on the weight of the finished board and the number of stacked layers, it controls the gripping force and stacking spacing of the palletizer, while simultaneously driving the transverse conveyor and transfer platform to achieve seamless material transfer. The cold pressing control module is connected to the circuit design of the lifting conveyor cold press, integrating temperature and pressure sensors. It constructs a correlation model between cold pressing parameters and board curing strength, automatically adjusting the cold pressing temperature, pressure, and holding time based on the board thickness to achieve curing.

When abnormal data is triggered, it automatically associates the corresponding process's sensing and detection records, parameter adjustment logs, and equipment operating status, providing complete data link support for fault diagnosis.

[0004] Furthermore, the central control unit incorporates a process cycle time coordination algorithm, which automatically adjusts the speed of the rapid conveyor platform 4 according to the production time of each process, so that the production cycle time difference between the preceding and following processes is ≤5s, avoiding board accumulation or process waiting.

[0005] Furthermore, both the first glue application control subsystem and the glue application control subsystem are equipped with anti-clogging early warning units in their glue supply adjustment modules. When the flow sensor detects that the glue supply flow rate is lower than the threshold, it automatically triggers the reverse cleaning action of the glue supply pump and issues an early warning signal.

Material preparation: Input the specifications of the calcium silicate board to be processed through the central control unit, including the board thickness, length, width, and number of composite layers; S2, Feeding and Conveying: The feeding and conveying control module starts the feeding and conveying platform.

After the gantry feeder completes the grabbing, it interlocks with the ready signal of the feeding end of the first fully automatic glue coating machine. If the glue coating machine has not completed the preliminary preparation, the feeder will pause its translation and remain in standby state. After the glue coating machine issues the ready signal, it will translate to the feeding end of the first fully automatic glue coating machine to accurately release the material. The positioning error is set at 0.3 mm ± 0.1 mm. S4, First application of adhesive: The adhesive supply adjustment module of the first adhesive application control subsystem adjusts the flow rate and pressure of the adhesive supply system according to the detection data of the board thickness sensor. The adhesive application execution module simultaneously adjusts the height and moving speed of the adhesive application machine nozzle to complete the uniform application of adhesive to the calcium silicate board.

If the cycle time difference between the preceding and following processes exceeds 5s, the conveying speed is automatically fine-tuned to 0.9-1.1m / s. The rock wool composite control module controls the placement machine to lay the cotton according to the preset 50mm rock wool thickness parameter, and then conveys it to the automatic rock wool composite machine to complete the composite at a speed of 0.6m / s and a pressure of 0.6MPa. The thickness detection sensor provides real-time feedback on the composite layer thickness to ensure that the error is ≤0.2mm. S6, Secondary Glue Application: The fast conveying platform transports the rock wool composite board to the second fully automatic glue application machine. The second glue application control subsystem adjusts the glue application parameters according to the base plate composite requirements to complete the secondary glue application on the surface of the composite board. S7, Four-sided positioning: The fast conveyor platform transports the board after secondary glue application to the board four-sided positioning machine.

S8, Base Plate Composite: The positioned sheet material is conveyed to the base plate composite machine. The base plate composite control module adjusts the pressing pressure and time according to the sheet material specifications to complete the pressing of the base plate and the composite plate. S9. Palletizing and Transfer: The gantry palletizer grabs and stacks the pressed boards in an orderly manner according to the instructions of the palletizing and transfer control module. The lifting transverse conveyor conveys the stacked boards to the lifting conveyor cold press. S10, Cold Press Curing: The cold press control module controls the temperature, pressure and holding time of the cold press, and adjusts the parameters in real time through temperature and pressure sensors to complete the cold press curing of the finished board; S11 Finished Product Transfer: The cold-pressed finished product boards are transported to the finished product board transfer platform by a lifting transverse conveyor. The transfer platform then transports the finished product boards to the designated storage location, completing the entire production process.

[0007] Furthermore, in steps S4 and S6, the glue application amount error of the glue application machine is designed to be less than 2%, and the glue application uniformity error is designed to be less than 3%.

[0008] Furthermore, in step S10, the temperature control range of the cold press is 15-35℃, the pressure control range is 0.3-0.8MPa, and the holding time is adaptively adjusted according to the thickness of the sheet material, with an adjustment range of 10-30min.

[0009] This invention provides a control system and production method for a fully automated calcium silicate board coating and laminating production line, which has the following beneficial effects: When in use, this invention uses a central control unit as the core, integrating control modules for the entire process of feeding, gluing, laminating, positioning, pressing, stacking, and cold pressing. Through a process cycle time coordination algorithm, it achieves precise linkage of various equipment, eliminates production cycle time differences, and improves the industrial production efficiency of calcium silicate boards.

[0010] In addition, both dual glue application control subsystems are equipped with thickness sensors and flow sensors, which can adjust glue application parameters in real time according to the specifications of the board material, ensuring uniform glue application, reducing reliance on manual labor, and lowering the defect rate.

[0011] In addition, the pressing parameters and cold-pressing curing parameters of the rock wool composite and the base plate composite are adjusted in real time through sensor detection, and industrial automatic control can improve product consistency.

[0012] In addition, the glue supply system is equipped with an anti-clogging early warning unit, and the entire production data can be stored and queried in real time, which facilitates quality traceability, realizes fully automated industrial control, eliminates the need for manual inspection and troubleshooting, and reduces labor costs.

Material preparation: Input the specifications of the calcium silicate board to be processed through the central control unit, including the board thickness, length, width, and number of composite layers; S2, feeding and conveying: The feeding and conveying control module starts the feeding and conveying platform (1). After the board arrival sensor detects the board, it immediately sends a signal to the central control unit. The conveying platform stops smoothly and triggers the interlock logic between the feeding and conveying control module and the gantry feeding control module to ensure accurate gripping position. S3, Gantry feeding: The gantry feeding control module collects the corner position information of the board according to the visual positioning sensor. After calibration by the visual recognition algorithm, it controls the mechanical claw to grab the calcium silicate panel. After the gantry feeding machine (2) grabs the panel, it interlocks with the ready signal of the feeding end of the first fully automatic glue coating machine (31). If the glue coating machine has not completed the preliminary preparation, the feeding machine will pause the translation and remain in standby state. After the glue coating machine issues the ready signal, it will translate to the feeding end of the first fully automatic glue coating machine (31) to accurately release the material. The positioning error is set at 0.3 mm ± 0.1 mm. S4, First application of adhesive: The adhesive supply adjustment module of the first adhesive application control subsystem adjusts the flow rate and pressure of the adhesive supply system according to the detection data of the board thickness sensor. The adhesive application execution module simultaneously adjusts the height and moving speed of the adhesive application machine nozzle to complete the uniform application of adhesive to the calcium silicate board. S5, Rock wool composite: After the rapid conveying control module collects the completion signal of the previous glue application and the ready signal of the subsequent rock wool placement machine (51), it conveys the board to the rock wool placement machine (51) at a speed of 1.0m / s; if the difference between the cycle time of the preceding and following processes exceeds 5s, the conveying speed is automatically adjusted to 0.9-1.1m / s; the rock wool composite control module controls the placement machine to lay the cotton according to the preset 50mm rock wool thickness parameter, and then conveys it to the rock wool automatic composite machine (52) to complete the composite at a speed of 0.6m / s and a pressure of 0.6MPa. The thickness detection sensor provides real-time feedback on the thickness of the composite layer to ensure that the error is ≤0.2mm; S6, Secondary glue application: The fast conveying platform (4) conveys the rock wool composite board to the second fully automatic glue application machine (32). The second glue application control subsystem adjusts the glue application parameters according to the composite requirements of the base plate to complete the secondary glue application on the surface of the composite board. S7, Four-sided positioning: The fast conveying platform (4) conveys the board after secondary glue application to the board four-sided positioning machine (6). The positioning control module controls the positioning claw action through the visual detection sensor and displacement sensor to complete the precise alignment of the board. The positioning error is ≤0.5mm. S8, Base plate bonding: The positioned plate is conveyed to the base plate bonding machine (7). The base plate bonding control module adjusts the pressing pressure and time according to the plate specifications to complete the bonding of the base plate and the bonding plate. S9. Palletizing and Transfer: The gantry palletizer (81) grabs and stacks the pressed plates in an orderly manner according to the instructions of the palletizing and transfer control module. The lifting transverse conveyor (82) transports the stacked plates to the lifting conveyor cold press (9). S10, Cold Press Curing: The cold press control module controls the temperature, pressure and holding time of the cold press, and adjusts the parameters in real time through temperature and pressure sensors to complete the cold press curing of the finished board; S11, Finished product transfer: The cold-pressed finished product board is transported by the lifting transverse conveyor (82) to the finished product board transfer platform (10), and the transfer platform transports the finished product board to the designated storage location to complete the entire production process.
