Exemplary method
The embodiment provides a method for controlling the cutting speed of a double-faced ceramic plate, which can be applied to an intelligent terminal of a ceramic tile cutting machine. As shown in fig. 1 in detail, the method includes:
s100, acquiring plate parameters of a double-faced ceramic plate;
in this embodiment, the conventional cutting process for the double-sided ceramic plate into a large double-sided ceramic plate is basically to cut the tile at a time from the upper surface of the tile using a single rotary cutting blade. The cutting process has the biggest characteristics of simplicity and convenience, but the quality of the broken surfaces of green bricks is poor, the lower surfaces of the bricks are easy to have edge breakage, and for large plates and thin plates, the thickness of the bricks needing to be cut at one time is large, so that the cutting pressure borne by the bricks is large, the ceramic large plates and thin plates are easy to damage in the cutting process, and a large number of cutting crack defects are caused. The plate parameters of the double-sided ceramic plate include: the dimensions and thickness of the double-sided ceramic plates, for example: the invention aims at the problems of edge breakage, corner breakage and cutting crack of the large ceramic plates, and firstly obtains plate parameters of the double-sided ceramic plates to prepare for subsequently adjusting the cutting speed.
Having obtained the plate parameters of the double-sided ceramic plate, the following steps can be performed as shown in fig. 1: s200, determining the cutting speed of the cutting knife when the cutting knife cuts the double-sided ceramic plate according to the plate parameters;
specifically, the cutting blade made of different materials and different thicknesses can be adopted according to different specifications and thicknesses of the ceramic large plate, and the cutting speed of the belt and the cutting speed of the cutting blade can be controlled according to different specifications and thicknesses of the ceramic large plate in the cutting process.
In order to determine a cutting speed for cutting the double-sided ceramic plate, the determining the cutting speed of the cutting knife for cutting the double-sided ceramic plate according to the plate parameters comprises the following steps:
s201, determining a running speed curve when the ceramic plate is driven by a belt to move according to the plate parameters; the running speed curve is used for representing the speed value of the ceramic plate driven by the belt corresponding to the distance between the double-sided ceramic plate on the belt and the cutting blade;
s202, determining the cutting speed for cutting the double-sided ceramic plate according to the speed value in the running speed curve.
In one implementation mode of the invention, the speed of the cutting blade is set to be unchanged, and a running speed curve when the belt drives the ceramic plate to move is determined according to the plate parameters, wherein the running speed curve is used for representing the speed value of the belt-driven ceramic plate corresponding to the distance between the double-sided ceramic plate on the belt and the cutting blade;
the cutting speed of the ceramic plate driven by the belt is controlled by the PLC. In practice, an operation speed curve of the ceramic plate driven by the belt is determined according to the plate parameters, and the cutting speed for cutting the double-sided ceramic plate is determined according to the speed value in the operation speed curve. For example: through the speed of fixing each cutting blade in advance, when electric eye senses ceramic brick entering cutting, can control the brick speed of walking of belt through PLC, the initial stage is walked the brick and is got into the cutting state with lower speed to begin to slowly accelerate and reach the top speed of settlement and carry out normal cutting, slowly slow down to suitable speed when treating fast cutting completion, the big board of pottery is walked out slowly along with the belt, and the cutting is accomplished.
For example, the first embodiment: the ceramic large plate is sintered at 1200 ℃ and has different specifications such as 1200 multiplied by 2600mm, 1500 multiplied by 3000mm, 1600 multiplied by 3200mm and the like, and 100 pieces of ceramic large plates with the same thickness (6mm) are used in the invention by taking 1200 multiplied by 2600mm as an example. Through the speed of fixing each cutting blade (two cutting blades above the brick, next cutting blade) in advance, when the electric eye sensed the ceramic brick and got into the cutting, can control the brick speed of walking of belt through PLC, the initial stage was walked the brick and is got into the cutting state with lower speed to begin to slowly accelerate and reach the top speed of settlement and carry out normal cutting, slowly slow down to initial velocity when treating fast cutting completion, the big board of pottery was walked out slowly along with the belt, and the cutting is accomplished. And testing the cutting quality effect, the cutting crack defect quantity and the yield.
Table 11200 x 2600mm specification 6mm thickness ceramic large plate double-sided cutting data
Under the condition that the table 1 has the same specification, the same thickness and the same cutting blade number, 100 ceramic large plates are adopted for testing, the cutting speed curve is optimized through adjustment through a first conventional scheme in a comparison table, the experimental optimization speed data is calculated and stored in a PLC control system, and the cutting speed curve can be optimized according to products with different specifications and thicknesses. Experiments show that the cutting crack defect can be improved by changing the cutting speed, and the yield is improved by more than 30% compared with the conventional rate under the condition of unchanging speed.
Example two: the ceramic large plate is sintered at 1200 ℃ and has different specifications of 1200 multiplied by 2600mm, 1500 multiplied by 3000mm, 1600 multiplied by 3200mm and the like, the invention takes 1200 multiplied by 2600mm as an example, and the ceramic large plate with different thicknesses (3mm, 6mm, 9mm and 12mm) which is produced in batches is cut at different speeds. Cutting experiments were performed using 100 pieces of ceramic large plates of different thicknesses, with different numbers of cutting blades (the number of cutting blades on the upper surface of the tile and the number of cutting blades on the lower surface of the tile) and speed profiles. And testing the cutting quality effect, the cutting crack defect quantity and the yield.
Table 212000X 2600mm specification ceramic large plate different thickness double-sided cutting data
Under the condition that the table 2 is the same in specification, different in thickness and different in cutting blade quantity, each 100 ceramic large plates are adopted for testing, the cutting speed curve is optimized through adjustment through 1 st, 2 nd, 3 rd and 4 th conventional schemes in a comparison table, the experimental optimization speed data is calculated and stored in a PLC control system, and the cutting speed curve can be optimized according to products with different thicknesses. Experiments show that the cutting crack defect can be improved by changing the cutting speed, and the yield is improved by about 40% compared with the conventional rate under the condition of unchanging.
The cutting speed control method can enable the cutting machine to start cutting at a lower speed in the initial cutting stage, gradually increase the speed through the PLC control system, enable the cutting speed to enter the normal speed, and gradually reduce the speed until the cutting is finished, so that the problems of edge breakage, corner breakage, cutting crack and the like are avoided.
In order to determine a cutting speed for cutting the double-sided ceramic plate, the determining the cutting speed for the cutting knife to cut the double-sided ceramic plate according to the plate parameters further includes the following steps: the determining the cutting speed of the cutting knife when cutting the double-sided ceramic plate according to the plate parameters further comprises: determining a cutting speed curve during the cutting action of the cutting blade according to the plate parameters, wherein the cutting speed curve is used for representing the speed value of the cutting blade corresponding to the distance between the double-sided ceramic plate on the belt and the cutting blade; the number of the cutting blades is a plurality; the cutting depth of the cutting blade is smaller than the thickness of the double-sided ceramic plate; and determining the cutting speed for cutting the double-sided ceramic plate according to the speed value in the cutting speed curve.
Specifically, can also set for ceramic big board belt drive ceramic plate speed unchangeable according to panel parameter, confirm the cutting speed curve of a plurality of cutting blade, when two-sided ceramic plate and blade distance change, control cutting blade's speed change to the depth of cut of every cutting blade on two-sided ceramic plate is all less, is less than two-sided ceramic plate thickness, can avoid two-sided ceramic plate to bear huge pressure. The belt through fixing good ceramic big board in advance drives ceramic plate speed, when the electric eye senses ceramic brick entering cutting, can control cutting blade's speed through PLC, the minimum speed of initial stage cutting motion to cut the work piece with this minimum speed. And when the cutting movement distance reaches a set value, gradually increasing the cutting speed to a normal cutting speed, and keeping the normal cutting speed to continuously cut the ceramic large plate until the cutting is finished. As shown in fig. 2, the thickness of brick is cut from the big board upper surface of pottery, and the big board of pottery of different thickness uses the cutting blade of different quantity, through the stack of cutting gap, and the cutting work upper surface all cuts downwards at the coplanar successive layer, and when the big board of pottery passed through first cutting blade, a cutting gap was cut out to the brick upper surface, and when the brick advanced along with belt speed, this cutting gap deepened to second cutting blade, analogizes in proper order. And finally, cutting the lower surface of the ceramic large plate for one time after the ceramic large plate is cut by a plurality of cutting blades on the upper surface of the ceramic large plate until the two sides of the brick are completely cut off. The cutting process is mainly characterized in that the cutting thickness of each rotary cutting mechanism is small, so that the cutting pressure born by the ceramic large plate and the thin plate brick is reduced.
In order to determine a cutting speed for cutting the double-sided ceramic plate, the determining the cutting speed for the cutting knife to cut the double-sided ceramic plate according to the plate parameters further includes the following steps: respectively determining a running speed curve of the ceramic plate driven by the belt and a cutting speed curve of the cutting blade according to the plate parameters; the running speed curve is used for representing the speed value of the ceramic plate driven by the belt corresponding to the distance between the double-sided ceramic plate on the belt and the cutting blade; the cutting speed curve is used for representing the speed value of the cutting blade corresponding to the distance between the double-sided ceramic plate on the belt and the cutting blade; the number of the cutting blades is a plurality; the cutting depth of the cutting blade is smaller than the thickness of the double-sided ceramic plate; and determining the cutting speed for cutting the double-sided ceramic plate according to the speed value in the running speed curve and the speed value in the cutting speed curve.
In another implementation mode of the invention, according to the plate parameters, respectively determining a running speed curve of the ceramic plate driven by the belt and a cutting speed curve of the cutting blade; and determining the cutting speed for cutting the double-sided ceramic plate according to the speed value in the running speed curve and the speed value in the cutting speed curve. The cutting speed of the ceramic plate and the cutting speed of each cutting blade are driven by the PLC control belt, so that the cutting speed of the whole ceramic large plate is adjusted. In fact, speed through fixing each cutting blade in advance and the belt of fixing the big board of pottery in advance drive the ceramic plate speed, when the electric eye senses ceramic brick entering cutting, can control the cutting speed that the belt drove the ceramic plate and control cutting blade's cutting speed through PLC, the speed and the cutting blade of brick are all with minimum speed in the initial stage, then the speed of walking the brick and the speed of cutting blade begin to slowly accelerate and reach the top speed of settlement and carry out normal cutting, treat when the fast cutting is accomplished, walk the brick and slowly slow down to initial velocity, cutting blade's speed keeps unchangeable, accomplish until the cutting.
The speed control method is used for realizing the three speed regulation methods, as shown in fig. 3, a speed regulation system of the speed control method comprises a PLC and a servo driver connected with the PLC, when the PLC moves to a certain distance from a ceramic large plate, the PLC obtains the current position and updates the speed parameter, and judges that acceleration or deceleration is completed when the PLC reaches the next distance, the PLC can control a speed curve of the ceramic plate and a speed curve of a cutting blade driven by a belt and send the speed curves to the servo driver, and the servo driver controls the belt and the cutting blade to move along with the speed curves, so that the continuous change of the speed parameters in the cutting process is achieved, and the cutting crack defect is reduced.
In another implementation manner of the present invention, the determining the speed of cutting the double-sided ceramic plate according to the plate parameter includes the following steps: and identifying the position of the double-sided ceramic plate in real time.
Specifically, after the cutting speed for cutting the double-sided ceramic plate is determined, the real-time position of the double-sided ceramic plate may be sensed by an electric eye sensor in the PLC system. Thus, the cutting speed of the double-sided ceramic plate is continuously adjusted as the distance between the double-sided ceramic plate and the cutting blade is changed.
Having obtained the cutting speed for cutting the double-sided ceramic plate, the following steps can be performed as shown in fig. 1: s300, performing cutting operation on the double-sided ceramic plate according to the cutting speed; correspondingly, the performing of the cutting operation on the double-sided ceramic plate according to the cutting speed includes:
s301, updating the cutting speed when the position changes;
and S302, executing cutting operation on the double-sided ceramic plate according to the updated cutting speed.
Specifically, as the belt drives the double-sided ceramic plate, the distance between the double-sided ceramic plate and the cutting blade is constantly changed, and initially, the speed is low, and then the belt drives the double-sided ceramic plate to advance at an accelerated speed, and when the double-sided ceramic plate is in contact with the cutting blade, the speed is accelerated to the highest speed. That is, if the speed of the belt-driven ceramic plate is changed and the speed of the cutting blade is not changed, when the double-sided ceramic plate and the cutting blade are close to each other, the speed of the belt-driven ceramic plate is set to a low speed, then the speed is increased to a maximum speed, and then the speed is slowly reduced to a stop. If the speed of the cutting blade is changed, the speed of the belt driving the ceramic plate is unchanged, and when the double-sided ceramic plate and the cutting blade are close to each other, the speed of the cutting blade is low, then the speed is accelerated to the highest speed, and then the speed is slowly decelerated to stop. If the belt drives the speed of the ceramic plate and the speed of the cutting blade are changed simultaneously, when the double-sided ceramic plate and the cutting blade are close, the speed of the cutting blade and the speed of the belt driving the ceramic plate start to adopt a very low speed, then accelerate to a maximum speed, and then slowly decelerate to a stop. And executing the cutting operation of the double-sided ceramic plate according to the updated speed. In another implementation, the cutting operation of the double-sided ceramic plate is performed according to the cutting speed, and then the method includes the following steps: storing the cutting speed in a control system. Therefore, automatic cutting operation of the double-faced ceramic plate is convenient to follow.
