AI Technical Summary
Existing cutting equipment is inconvenient to replace cutting discs when cutting stones of different sizes, especially when the radius of the cutting disc of large equipment is smaller than that of the stone. Furthermore, the sensing mechanism cannot adapt to changes in the size of the stone, resulting in incomplete cutting or equipment damage.
An external automatic data acquisition device is adopted, equipped with an inductive sensor and controller. The distance between the saw blade and the stone is determined by the sensing mechanism, and the cutting control method is optimized, including adjusting the zero point height and graded detection, to avoid the sensing mechanism from descending blindly.
This achieves efficient adaptation of the cutting equipment to different stone sizes, avoids damage to the sensing mechanism, and improves cutting accuracy and equipment lifespan.

Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of cutting equipment, in particular to a cutting machine and a cutting control method thereof. BACKGROUND
[0002] The structure of the cutting machine varies according to different cutting objects. The cutting machine for cutting stone has a gantry bridge cutting machine device.
[0003] The gantry bridge cutting machine device is a cutting device for cutting large-volume stone and is commonly used in large workshops for stone cutting and transportation. According to the size of the gantry, the cutting mechanism to be matched also needs to be adapted to meet the cutting of stone of multiple specifications. The cutting device in the prior art can complete multi-axis cutting action, but the effect is not good when recording the data of the cut stone. There is a lack of devices and equipment that can record the length of the cut stone on the market. How to solve the problem of how to comprehensively collect the length, width and height of the cut stone by the cutting device and how to avoid possible situations in actual application to better meet the processing requirements is the technical problem that the inventor wants to solve. SUMMARY
[0004] Other features and advantages of the present application will be set forth in the following specification, and in part will be apparent from the specification, or can be learned by practice of the present application. The objects and other advantages of the present application will be realized and attained by the structure particularly pointed out in the specification as well as in the other illustrative figures.
[0005] In the prior art, the cutting device needs to cut stone of different sizes. Small cutting devices have the possibility of replacing the cutting blade when the cutting blade radius is smaller than the stone to be cut. However, if a large cutting device encounters a cutting blade radius smaller than the stone to be cut, the cutting blade is not convenient to replace due to the size of the cutting blade. In actual production, stone processing plants often use tower-type multi-saw blades when using large cutting devices such as large gantry bridge cutting machine devices. The stone processing plant sets the largest saw blade according to the largest specification of the processed stone. One saw blade corresponds to a size that can best cut the stone. At this time, if the processed stone is replaced, the size of the cut stone becomes smaller. On the one hand, the gantry bridge cutting machine can start to repeat the previous action stroke, but it cannot cut completely, so the gantry bridge cutting machine needs to be adjusted. On the other hand, without adjustment, the sensing mechanism will also be out of the range of use because the size of the stone is smaller, causing the gantry bridge cutting machine to fail to trigger cutting.
[0006] The present application aims to overcome the above-mentioned shortcomings and provide a cutting machine and a cutting control method thereof.

[0065] According to some embodiments of the application, the sensing mechanism 2 is an inductive sensor. The working principle of the inductive sensor is that the mechanism drops from zero height, the probe part collides with the rough material, drives the entire rod body to twist, so that the sensor in the mechanism is connected to generate a signal to complete triggering.
[0066] According to some embodiments of the application, the saw blade 3 is provided with one, the main shaft is provided with a cutter holder 10, and the saw blade 3 is locked and installed on the main shaft through the front and rear cutter holders 10.

[0068] According to some embodiments of the application, the saw blade group is a tower type structure.
[0069] According to some embodiments of the application, the cutting machine comprises a driving mechanism, a cutting mechanism and a controller, the controller is electrically connected with the sensing mechanism, the stone cutting machine moves along the X axis, the Y axis and the Z axis through the driving mechanism, the stone cutting machine judges the distance between the saw blade and the stone through the sensing mechanism, and the controller controls the lifting and data acquisition of the sensing mechanism.

[0071] The present embodiment also provides a cutting control method of a cutting machine, the stone cutting machine controls the cutting mechanism to move along the X-axis, Y-axis, and Z-axis through the driving mechanism, the X-axis movement is forward and backward movement, the Y-axis movement is left and right movement, and the Z-axis movement is up and down movement, and the controller controls the stone cutting machine to perform the following action steps:
[0072] ①The Y-axis moves from the left limit to the right limit, the stone cutting machine device is provided with left and right limit values, and the stone cutting machine moves along the Y-axis to the outer edge of the stone by at least 100 mm;
[0073] ②The Z-axis is lowered by a cutting amount, and the cutting amount is a device setting value;
[0074] ③The Y-axis moves from the right limit to the left limit;
[0075] ④The Z-axis is lowered by a cutting amount;
[0076] ⑤Steps 1-4 are repeated several times until the Z-axis moves to the cutting depth, and the cutting depth is a device setting value;
[0077] ⑥The Z-axis is raised to the zero height, the zero height is a device setting value, and the largest saw blade in the saw blade set is completely above the stone in the Z-axis direction;
[0078] ⑦The X-axis moves forward by a slicing amount, the slicing amount is a device setting value, and the slicing amount = the thickness of the stone slab + the thickness of the saw blade head;
[0079] ⑧The Z-axis is lowered to a half cutting amount, and the half cutting amount is a device setting value, and the half cutting amount = the cutting depth - the radius difference of the adjacent saw blade;
[0080] ⑨Steps 1-8 are repeated until the X-axis direction of the largest saw blade moves out of the rough material;
[0081] ⑩The X-axis is reset to the zero position; the X-axis zero position is a device self-provided value.
[0082] According to some embodiments of the present application, the controller calculates the cutting area, the cutting area = the cutting depth * the cutting length, and the cutting area starts to be calculated after the stone cutting machine completes step ⑦, because the controller does not collect the maximum coordinate points of the respective three-axis directions of the machine before slicing.
[0083] According to some embodiments of the present application, the cutting depth = the highest point of the Z axis - the lowest point of the Z axis, the lowest point of the Z axis being collected by the stone cutting machine in the step ⑤, and the highest point of the Z axis being collected by the stone cutting machine in the step ⑥.
[0084] According to some embodiments of the present application, the cutting length = the length of the probe of the sensing mechanism 2 contacting the stone.
[0085] According to some embodiments of the present application, the sensing mechanism 2 is divided into sensor A and sensor B, any one of sensor A or sensor B is located above the edge of the stone, the sensing mechanism 2 is lowered when the Y axis starts to walk, and stops lowering after the probe of any one of the sensors contacts the stone, the sensing mechanism 2 maintains the height from the starting point to the limit of the other end of the Y axis and then rises, the cutting length = the installation distance of sensor A and sensor B + the displacement distance of the probe of any one of sensor A and sensor B.
[0086] According to some embodiments of the present application, the stone cutting machine collects the data of the cutting thickness through the sensing mechanism 2 and the controller, the cutting thickness = the thickness of the saw blade + the thickness of the saw blade.
[0087] Referring to Figure 3 , Figure 3 The figure is a schematic diagram of the position relationship between the sensing mechanism and the stone when the cutting machine cuts the stone.
[0088] Taking the left-to-right example: when the sensing mechanism 2 is lowered, the sensing mechanism 2 is divided into sensor A and sensor B, the probe of sensor B at the right end of the saw blade center contacts the rough stone, the sensing mechanism stops lowering and maintains the height when the sensor generates a signal, and then the sensing mechanism 2 walks along with the saw blade cover 1 and the saw blade Y axis direction.
[0089] The probe of sensor A contacts the rough stone ①, and the probe of sensor B is separated from the rough stone ②, the distance between the two points + the installation distance of sensor AB = the length of the stone slab being cut in the rough stone (I);
[0090] The probe of sensor B contacts ③, and the probe of sensor B is separated from ④, the distance between the two points = the length of the stone slab being cut in the rough stone (II); similarly, the length of the stone slab being cut in the rough stone (III) is calculated; the cutting thickness: the thickness of the saw blade + the thickness of the saw blade = the cutting thickness. The cutting area is calculated by the cutting depth and the cutting length, and the cutting thickness is also collected as the product specification.
[0091] According to some embodiments of the present application, the sensing mechanism 2 is divided into sensor A and sensor B, both of which are located outside the stone edge (the distance between sensor A and sensor B is less than the length of a single stone), and the sensing mechanism 2 controls the distance of the sensing mechanism 2 through the control method.
[0092] The structure of the stone cutting machine is different, and the size specifications of the cut slabs are also different. For example, the specifications of the slabs produced by the gantry bridge cutting machine equipment are 450-1000mm, and in actual production, the commonly cut size specifications are 600-900mm. The slab specifications are 50mm each, such as 600, 650, 700, 750, 800, 850, 900.... The relationship between the actual use of the saw blade specification and the normal use of the saw blade specification for the produced slab specification is n, n=(actual use of the saw blade radius-normal use of the saw blade radius for the produced slab specification) / 50, n is used to represent the difference level number of the corresponding slab of the saw blade and the actual production slab specification, such as the maximum saw blade in the tower-shaped saw blade group is 1900mm, and the 1900mm saw blade is normally used to cut 700mm size slabs, and in actual production, temporary processing of 600mm size slabs is required, at which time replacing the saw blade is undoubtedly time-consuming and laborious. The corresponding maximum saw blade in the tower-shaped saw blade group for 600mm size slabs is 1700mm, so the controller and control program are used to adjust the position of the saw blade, so that the saw blade can cut completely when cutting 600mm slabs. Because the position of the saw blade can only completely cut 700mm size slabs, and the position of the saw blade cannot be lowered, the cutting requirement cannot be met. The formula n=(1900 / 2-1700 / 2) / 50=2. That is, the difference between the used saw blade and the slab is 2 levels, which are 650mm and 700mm. When cutting 700mm size slabs, the saw blade is in the initial position, and needs to be adjusted to the cutting position of 650mm size slabs, at which time the sensing mechanism 2 still cannot detect the slab, and then it is lowered to the cutting position of 600mm size slabs, and the sensing mechanism 2 can detect and cut.
[0093] Example Two
[0094] Reference Figure 1 and Figure 4 , Figure 1 is a structural schematic diagram of a cutting machine of the present application, Figure 4 is a logic diagram of the sensing mechanism lowering control of the cutting machine of the present application.
[0095] Further, based on the above cutting machine and its cutting control method, in actual production application, the stone cutting machine often cuts multiple stone blocks spliced together, and the edges of the unprocessed stone blocks are often uneven and still have gaps when spliced together. When the sensing mechanism 2 is lowered and the probe is just located in the gap between the rough materials (stone), the sensing mechanism 2 will continue to descend, and at this time the sensing mechanism 2 is located in the gap, and the cutting machine will move to cause the sensing mechanism 2 to collide with the stone.
[0096] At the same time, in actual production, there may also be a situation of cutting small specifications with large saw blades, for example: a 1900mm saw blade normally cuts a 700mm wide strip, but due to urgent orders, a batch of 600mm wide strips need to be cut immediately (600mm wide strips generally use a 1700mm saw blade), in order to save the time of replacing the saw blade and adjusting the machine, the actual operation does not replace the saw blade and directly processes, which will cause the height of the sensor from the stone to increase by 100mm, so that the sensor cannot detect the stone and cannot collect data, causing the stone cutting machine to be unable to be used normally. If the sensing mechanism 2 is blindly controlled to descend, the sensing mechanism 2 will always collide with the stone before stopping, and if the probe of the sensing mechanism 2 is in the gap between the stones when it is descending, it will be misjudged as the mechanism descending distance being insufficient, and the mechanism will continue to descend, which will cause the bottom of the mechanism to be lower than the upper surface of the stone, and the mechanism will collide with the stone during equipment operation, causing damage.
[0097] Based on this, the embodiment provides a cutting control method for a cutting machine, n saw blades are arranged on the stone cutting machine, the n saw blades are installed on a cutter seat to form a tower-shaped saw blade group, the largest diameter saw blade on the tower-shaped saw blade group is a saw blade M, the strip width value corresponding to the cutting of the saw blade M is P, and the control method is as follows:
[0098] ①The sensing mechanism 2 detects from the normal initial position of the strip with a cutting width value of P, the sensing mechanism 2 is an inductive sensor, the installation height of the sensor requires that the bottom of the probe and the lower edge of the cutter seat are on the same horizontal line, and the cutter seat is a circular seat for clamping the saw blade;
[0099] ②If detection is detected, cutting is started, if detection is not detected, the controller controls the sensing mechanism 2 to descend by 50mm each time for re-detection;
[0100] ③The sensing mechanism 2 needs to be lowered before the lowest point of the Z axis after each slicing, the height before the lowest point of the Z axis is H, and H> cutting depth.n. H is the advance amount of the Z axis to the lowest point, for example, the lowest point of the Z axis is 630mm, and the sensing mechanism 2 needs to be lowered at 605mm, and at this time H = 25mm. The sensing mechanism 2 is lowered by relying on a closed ball screw sliding module to realize lifting adjustment. H> cutting depth.n, and the purpose is to have enough tool path times to satisfy repeated detection of the mechanism whether it is the next specification strip;
[0101] IV. If the maximum blade corresponds to the size of the produced slab, the sensor can be detected at the L0 position, L0 = maximum blade radius - cutter seat radius - minimum cutting amount + H + cutter height + allowance; if the maximum blade does not correspond to the size of the produced slab, the sensor cannot sense the stone at the L0 position, the sensing mechanism 2 continues to descend until the stone to be cut is detected,
[0102] L1 = 50 - down cutter amount * 1;
[0103] L2 = 50 - down cutter amount * 2; ...
[0105] Ln = 50 - down cutter amount * n.
[0106] According to some embodiments of the present application, the minimum cutting amount refers to the amount of cutting per size, for example, the cutting amount of a 600mm slab is generally between 630-680mm, and 630 is the minimum cutting amount, and the allowance is generally 10mm.
[0107] According to some embodiments of the present application, the probe is forced to twist the direction during the turning process after walking to the left / right limit in the Y axis, and the forced twisting direction causes the probe to easily malfunction. If the probe uses a roller, it is easy to wear out after a long time of walking on the stone, and its service life is not ideal. Therefore, a small amount of upward movement is required before the distance to the left / right limit of the Y axis, the purpose is that the probe does not contact the stone during the turning process, and then a small amount of downward movement of the sensing mechanism 2 is required when the Y axis starts to walk in the opposite direction. At this time, the upward distance and the downward distance are equal. It will not affect the calculation of the cutting length.
[0108] When the Y axis walks to the left, the left probe has walked out of the stone (the sensor signal is disconnected) and the distance between the signal disconnection position and the left limit is less than the length of the stone, then the sensing mechanism 2 is slightly raised, and when the Y axis starts to walk to the right, the sensing mechanism 2 is slightly lowered. The same applies to the right; the small amount of upward movement requires that the other probe in contact with the stone can be completely above the stone, for example, when the Y axis walks to the left, the left probe has walked out of the stone, and the right probe is still on the stone. The small amount of upward movement is to make the right probe higher than the stone so as not to be forced to twist the direction.
[0109] According to some embodiments of the present application, the adjustment of the probe height is realized by the lifting of the closed ball screw sliding table module, and the probe is the sensing element of the sensor. The selected module stroke is 200 mm, and the adjustment distance is 50 mm each time. The module with a stroke of 200 mm can be adjusted twice for 50 mm, and the remaining 25 mm is reserved to avoid overstroke of the module.
[0110] For example, a 1900 mm saw blade can be used to produce a 700 mm strip, and the first drop L0 is controlled to reach the 700 mm strip during installation. If the sensor has no signal, it means that the produced strip is not 700 mm. The second drop L1 is used to sense the 650 mm strip, and the sensor still has no signal, which means that the strip is not 650 mm. The third drop L2 is used to sense the 600 mm strip, and so on.
[0111] The module stroke can be selected according to the requirements. For example, the maximum saw blade used in the customer's cutting equipment is a 1900 mm saw blade, and it needs to cut strips below 600 mm. Therefore, a larger specification closed ball screw sliding table module needs to be selected to meet the requirements.
[0112] According to some embodiments of the present application, the sensor mechanism is lowered by L0 when the Z-axis reaches the H height or before. H is the advance amount when the Z-axis reaches the lowest point. For example, the original lowest point of the Z-axis is 630 mm, and the sensor mechanism needs to be lowered at 605 mm during adjustment. H = 25 mm. The probe does not contact the rough material (stone), the sensor mechanism maintains the height, and the back knife is walked once. The probe does not contact the rough material in the interval, the sensor mechanism is lowered by L1, and the back knife is walked once again for detection until the rough material is contacted, and the cutting equipment moves along the Z-axis to the upper limit of the adjustment, and the detection is not performed. The sensor mechanism is lowered for the first time, the probe contacts the rough material, and the delay stops the lowering. The back knife is walked twice (Y-axis walking to the left / right limit is called once back knife), and the controller calculates the cutting length mechanism after the back knife is walked twice. The sensor mechanism is lowered for the second time, and the probe of the sensor contacts the rough material. The measured value of the second back knife after the rough material is contacted is recorded as the data value of the sensor acquisition.
