Description

Technical Field

[0001] The present application relates to the field of automation control technology, and in particular to an intelligent control system for rotary cutting. Background Art

[0002] Mechanical cutting is mainly divided into wire cutting and rotary cutting. Wire cutting means that the tool moves back and forth in a straight line to achieve cutting, while rotary cutting means that the tool cuts the object after rotating. Compared with wire cutting, rotary cutting takes up less space and the tool often rotates faster.

[0003] However, it is precisely because of the high-speed rotation during peeling that it has the following shortcomings:

[0004] People buy cutting equipment for factories and specific jobs, but they often don't use it to cut just one or two items. This is especially true in home environments, where the equipment is used as needed and the materials to be cut vary greatly. In this case, if the peeling speed is consistent, waste will inevitably occur. Therefore, the peeling speed needs to be changed, for example, several gears should be set for the peeling equipment so that users can adjust it by themselves.

[0005] However, for most users, especially those in home use scenarios, even if the manufacturer provides instructions on how much speed should be adjusted for cutting different materials, most users will not necessarily read or write them down carefully, especially when the instructions contain a lot of content, resulting in many functions designed by the manufacturer not being used by users, or incorrect adjustments may increase the chance of damage to the blade, etc. Therefore, the present application proposes a new technical solution.

[0043] The following is combined with Figure 1-Figure 3 This application is described in further detail.

[0044] The embodiment of the present application discloses an intelligent control system for rotary cutting.

[0045] Reference Figure 1-Figure 3 , an intelligent rotary cutting control system is used in rotary cutting equipment in industrial and household scenarios. The preferred embodiment of this invention is: the rotary cutter is fixed in position, that is, the rotary cutter will not move forward, backward, up or down. In this context, the material moves toward the rotary cutter and then cuts.

[0046] The intelligent control system for rotary cutting includes a material measuring mechanism 1, a synchronous safety lock 2 and a control module 3. The material measuring mechanism 1 is installed on the side of the rotary cutting tool and contacts the material to detect the hardness of the material before cutting the material; the control module 3 outputs control data of the matching motor according to the detection feedback of the material measuring mechanism 1. The motor is a motor used by the equipment to drive the rotary cutting tool to rotate.

[0047] Specifically, the material measuring mechanism 1 includes a multi-stage sheath 11, a touch rod 12, a spring 13, a middle plate 14, a spring 2 15, a middle plate 2 16 and a conductive rod 17.

[0048] Among them, the multi-step sheath 11 is provided with a central channel along the central axis, and is used to be installed on the side of the rotary cutting tool; for example: the rotary shaft seat of the rotary cutting tool, the screw-fixed structural block on the tool cover, one end of the multi-step sheath 11 is inserted and screwed on the structural block, and the other end faces the downward cutting direction of the rotary cutting tool, and is parallel to the rotary cutting tool (blade).

[0049] The feeler rod 12 extends into the central channel, and one end extends out as a test end, and the extended position exceeds the rotary cutting tool; the test end of the feeler rod 12 is fixed with a sphere or made into a spherical shape to improve the contact effect.

[0050] One end of the spring 13 is fixed to one end of the touch rod 12 extending into the central channel, and the other end is preferably fixed to a ring plate to facilitate the installation of the spring 13; the ring plate can also contact the inner wall at the corresponding section of the central channel to guide the spring 13 to retract.

[0051] The middle plate 14 is located in the multi-step sleeve 11. The middle plate 14 is located at the end of the spring 13 away from the touch rod 12 and perpendicular to the central channel. It should be noted that the middle plate 14 is not fixed but can move axially in the multi-step sleeve 11, so its thickness cannot be too thin to avoid tilting.

[0052] The spring 2 15 is located in the multi-step sheath 11 and on the side of the middle plate 14 away from the spring 1 13 ; the diameter of the spring 2 15 is greater than that of the spring 1 13 .

[0053] The second middle plate 16 is located in the multi-stage sheath 11 and at the end of the second spring 15 away from the first middle plate 14 ; the second middle plate 16 and the second spring 15 are fixed and have an axial opening, and the hole is adapted to the conduction rod 17 .

[0054] The conductive rod 17 passes through the axial hole of the middle plate 2 16 and one end is fixed to the middle plate 1 14. The synchronous safety lock 2 is connected in parallel with the motor corresponding to the rotary cutting tool and is used to pull the conductive rod 17 away from the contact rod 12 when the power is turned on, that is:

[0055] When the material moves toward the rotary cutting tool, the material will first approach the feeler rod 12 and apply force to it. The feeler rod 12 squeezes the spring 13 to store force, and the feeler rod 12 applies force to the material; when the motor is powered on to start the rotary cutting tool, the synchronous safety lock 2 pulls the conduction rod 17 away from the feeler rod 12. Because the conduction rod 17 and the middle plate 14 are fixed, the middle plate 14 is also pulled away from the feeler rod 12 and no longer cooperates with the spring 13 to prevent the feeler rod 12 from retreating. At this time, the reaction force generated by the material pushes the feeler rod 12 to retreat.

[0056] According to the deformation characteristics and the principle that forces act on each other, the retreat distance of the feeler rod 12 will be different for materials with different hardness. Therefore, the approximate hardness can be estimated based on the empirical data obtained from the test by simply knowing the position change of the feeler rod 12.

[0057] It should be noted that this application is not a real material hardness testing device, but to know the approximate hardness of the material to be cut by the rotary cutter. When there is a big difference in hardness, adjust the rotation speed of the rotary cutter. That is, the precision requirement is not high; for example: a piece of tofu and a piece of meat can use the same rotation speed; when cutting tofu, change to cutting wood and large bones, adjust the rotation speed. Therefore, there is no need to use a formula to estimate the material hardness and then analyze it. As long as the relationship between the retreat range of the touch rod 12 and the motor speed is obtained by testing, it can be used.

[0058] Meanwhile, the above structural setting has another advantage: when the retreat amount of the feeler rod 12 is obtained, that is, when the current rotation speed that should be matched can be analyzed, the feeler rod 12 can retreat, which can reduce the obstruction to material cutting.

[0059] How to obtain the retreat amount of the feeler rod 12, specifically:

[0060] A plurality of groups of conductive points are axially arranged on the wall of the central channel, each group of conductive points has two conductive points and are symmetrically distributed with respect to the central axis of the multi-stage sheath 11; a conductive ring 18 is fixed on the touch rod 12 or the spring 13, and the conductive ring 18 is preferably embedded on the touch rod 12. Each group of conductive points is electrically connected to the control module 3, for example: one conductive point is connected to the output pin, and the other is connected to the input pin. When the touch rod 12 is driven to move, the conductive ring 18 slides over each conductive point, and the control module 3 can obtain the retreat amount of the touch rod 12 according to the pin number and quantity of the feedback signal; the control module 3 is configured to: output motor control data 1 according to the feedback of each group of conductive points; for example: assuming that each group of conductive points differs by 2mm, then if the three pins return a high-level signal at this time, it can be obtained that the touch rod 12 retreats by 4mm-6mm; and then the motor speed can be obtained according to the matching relationship between the retreat amount of the touch rod 12 and the motor speed recorded in advance. If the motor is a servo motor, the control module 3 includes a controller and a servo drive controller, and the motor control data 1 is the corresponding pulse parameter; if the motor is a motor controlled by a frequency converter, the control module 3 includes a controller and a frequency converter, and the motor control data 1 is the frequency control parameter of the frequency converter. It is understandable that the speed control of the servo motor and the output control of the frequency converter are existing technologies, so they are not described in detail.

[0061] According to the above settings, after the application is applied, the hardness of the material can be detected before cutting, and the motor speed can be automatically adjusted according to the hardness, which can better help users adjust the rotary cutting speed.

[0062] In one embodiment of the present application, the multi-step sheath 11 includes a fixed tube 111 and multiple movable tubes 112 with the same central axis, the multiple movable tubes 112 are fixed to each other and an outermost movable tube 112 is sleeved on one end of the fixed tube 111, the multiple movable tubes 112 have different diameters and the diameter decreases as they are farther away from the fixed tube 111; in this embodiment, the number of movable tubes 112 can be three, the interior of the smallest diameter is the touch rod 12 and the spring 1 13, the interior of the second largest diameter is the middle plate 1 14, the interior of the largest diameter is the middle plate 2 16, and the middle plate 2 16 is also in front of the fixed tube 111.

[0063] According to the above arrangement, the diameters of the various sections of the multi-stage sheath 11 are different, which can not only constrain the internal structure but also limit the various movable structures.

[0064] The fixed tube 111 is an insulating section, and the synchronous safety lock 2 is installed on the insulating section. The synchronous safety lock 2 includes a guide rail 21, a slider 22 and a lock pin 23.

[0065] There are two guide rails 21 symmetrically arranged along the central axis of the insulating section, and the guide rails 21 are fixed to the inner wall of the insulating section; guide grooves 211 extending along the length direction are provided on the opposite sides of the two guide rails 21; the slider 22 is located between the two guide rails 21, and the locking pin 23 penetrates the slider 22 and the end is inserted into the guide groove 211; the guide rail 21 (after being connected in series with a current limiting resistor) is connected in parallel with the motor corresponding to the rotary cutting tool.

[0066] It should be noted that the above mechanism requires the motor to be a DC motor, using DC power supply, rather than AC power, to prevent the slider 22 from moving incorrectly. The slider 22 and the conductive rod 17 are fixed and the conductive rod 17 is insulated, such as a ceramic rod.

[0067] According to the above configuration, when the motor is powered on, the guide rail 21 is powered on synchronously, and the current flows through the guide rail 21, under the guidance of the lock pin 23, through the slider 22 and then out of the other guide rail 21; in this process, according to the electromagnetic principle and the right and left hand determination, it can be inferred that the slider 22 can be driven to move along the guide rail 21. It is only necessary to select which guide rail 21 is connected to the positive pole, so that the slider 22 can be kept away from the middle plate 2 16 when the motor is powered on; because the slider 22 and the conduction rod 17 are fixed, the conduction rod 17 is pulled at this time, so that the middle plate 1 14 compresses the spring 2 15. When the motor is powered off, the spring 2 15 recovers to reset the middle plate 2 16.

[0068] In another embodiment of the present application, in order to prevent the multi-step sheath 11 and the feeler rod 12 from directly inserting into the material or hindering the material from moving toward the rotary cutting tool when the rotary cutting tool cuts to a large depth, the present application also includes a cooperative pushing mechanism 4.

[0069] The cooperative pushing mechanism 4 includes a connecting rod 41, a slide 42 and a bottom plate 43. The bottom plate 43 is located in front of the rotary cutting tool and is fixed, such as: fixed to the structural frame of the equipment; the bottom of the slide 42 is T-shaped and slidably connected to the bottom plate 43, and the sliding direction is parallel to the multi-stage sheath 11; the slide 42 is used to contact or follow the material to be cut and move synchronously, for example: the material placed on the slide 42 is pushed toward the rotary cutting tool; the connecting rod 41 can be L-shaped and one end fixes the slide 42, and the other end extends to the front of the end of the largest diameter movable tube 112 (that is, the connecting rod 41 moves toward the tool and will contact the end surface of the largest diameter movable tube). An anti-slip ring is set in the smallest diameter movable tube 112, and the end of the touch rod 12 forms a tail plate with a diameter greater than the inner diameter of the anti-slip ring. One end of the guide rail 21 is fixed to the middle plate 16, and the middle plate 16 is insulated and fixed to the inner wall of the largest diameter movable tube 112.

[0070] According to the above arrangement, when the material is pushed toward the rotary cutting tool, the slide 42 also moves toward the rotary cutting tool. After the slide 42 moves to a certain position, the movable tube 112 is pushed toward the fixed tube 111 by the connecting rod 41, and the overall length of the multi-stage sheath 11 is shortened to reduce interference with the cutting of the fed material.

[0071] At the same time, because the middle plate 16 is fixed to the movable tube 112, the plate 16 will also move toward the fixed tube 111 during this process, and the middle plate 16 will drive the connected guide rail 21 to move; at this time, although the slider 22 between the guide rails 21 may be stagnant in the original position, because the slider 22 cannot leave the space between the two guide rails 21 and is blocked by the middle plate 16, the slider 22 will also move, that is, the synchronous safety lock 2 moves to prevent the synchronous safety lock 2 from failing after the displacement; and the movement of the slider 22 pulls the middle plate 14 to move through the transmission rod 16, that is, to make the middle plate 14 give up its position, so that the touch rod 12 will be directly pushed backwards by the material without any obstruction.

[0072] In another embodiment of the present application, the present application also includes a material measuring mechanism 2 5, which includes an ultrasonic module 51 for emitting and receiving ultrasonic waves. The ultrasonic module 51 is composed of an integrated circuit, which at least includes a probe and a transmitting circuit and a receiving circuit electrically connected to the probe; it can be understood that ultrasonic probes and ultrasonic detection are existing technologies, so they are not described in detail; if the returned data is an analog signal, an analog-to-digital converter 52 can be configured, that is, ADC is used to convert the signal and then connect it back to the control module 3.

[0073] The transmitting and receiving part (i.e., the probe) of the ultrasonic module 51 is fixed to the bottom plate 43 , the slide seat 42 is provided with a structural groove extending along the sliding direction, the transmitting and receiving part of the ultrasonic module 51 extends out of the structural groove, and the ultrasonic module is electrically connected to the control module 3 .

[0074] As can be seen from the foregoing, the material to be cut can be placed on the slide 42 and pushed toward the rotary cutting tool, so the ultrasonic module 51 can emit ultrasonic waves to the material for detection when the material passes by;

[0075] It is known that the transmission of ultrasound waves in different densities and elastic moduli is different. After the returned signal is converted into an electrical signal, it can be expressed in the form of waves on the time axis. Referring to the display effect of the oscilloscope, the propagation speed of hard materials such as metals is faster, and the waveform will be shorter in period.

[0076] Therefore, the control module 3 can estimate whether the hardness of some materials has changed relatively significantly based on the signal fed back by the ultrasonic module 51; correspondingly, the control module 3 is configured as follows:

[0077] Estimate the hardness change data of the material according to the feedback of the ultrasonic module 51; for example, compare the waveform period changes at each time sequence between two adjacent detections;

[0078] If the hardness change data indicates that the hardness increases, such as: the waveform period becomes smaller, then the motor speed increase control instruction is output as the motor control data 2;

[0079] If the hardness change data indicates that the hardness decreases, a motor speed reduction control instruction is output as motor control data 2.

[0080] Among them, the increase value and decrease value in the motor speed increase control instruction and the motor speed decrease control instruction can be fixed presets, for example: the speed is divided into three gears: low, medium and high; if it increases, it increases to high gear, and if it decreases, it decreases to low gear; more precisely: establish a corresponding relationship between the waveform of the feedback signal of the ultrasonic module 51 and the speed, and obtain the speed increase / decrease amount according to the speed corresponding to the current waveform-the current actual speed.

[0081] In another embodiment, considering that for a rotary cutting tool, if the rotation speed suddenly changes when cutting from a soft object to a hard object, the insufficient strength of the rotary cutting tool may easily cause damage to the tool, the control module 3 is configured as follows:

[0082] Obtaining the moving speed v of the slide 42 and the distance d between the transmitting and receiving parts of the ultrasonic module 51 and the blade edge of the rotary cutting tool;

[0083] The cutting waiting time t is calculated according to the speed formula (i.e., v=d / t);

[0084] The control purpose of the motor control data 2 is gradually completed within the time length t. For example, if the speed increases by 100rpm and t=2s, the acceleration is gradually increased by 100 / 2 to reduce the chance of damage to the tool.

[0085] In another embodiment, the transmitting and receiving part (i.e., the probe) of the ultrasonic module 51 is a lifting structure. Specifically, the electric push cylinder 6 is fixed on the base plate 43, the electric push cylinder 6 faces upward and the probe is fixed at the rod end, and the electrical signal of the electric push cylinder 6 is connected to the control module 3.

[0086] According to the above settings, the user can adjust the probe position of the ultrasonic module 51 according to actual needs, so that it can contact the material for detection or stay away from the material without detection, etc.; the upper side edge of the probe is preferably arc-shaped.

[0087] Furthermore, the control module 3 is also electrically connected to a distance measuring unit 7, which may be a laser distance sensor and is fixed on the bottom plate 43 in an upwardly tilted manner. The control module 3 is configured as follows:

[0088] The height of the material (from the bottom plate 43) is obtained based on the trigonometric function, the tilt angle of the distance measuring unit 7 and the detection value; for example: if the tilt angle is 30° and the detection value is 6 cm, the height is 3 cm.

[0089] The lifting and lowering of the electric push cylinder 6 is controlled according to the height of the material. For example, the probe at the rod end of the electric push cylinder 6 can initially contact the material at a height of 2 cm. At this time, the height is 3 cm, and the electric push cylinder 6 extends 1 cm.

[0090] Furthermore, the slide 42 fixes a plurality of scale bars 421 at the opening of the structural groove, and the plurality of scale bars 421 are distributed at intervals along the length of the structural groove. The control module 3 can be configured as follows:

[0091] Obtaining the detection value of the scale bar 421 when it passes through the detection path of the distance measuring unit 7;

[0092] The moving speed v of the slide 42 (i.e., the material) is calculated based on the change in the detection value of the distance measuring unit 7 and the spacing between the pre-recorded scale bars 421. For example: when the detection value is 6 cm, the detection line falls on the scale bar 421; the two adjacent detection values ​​of 6 cm are 4s apart, and the spacing between the scale bars is 4cm, then v=4cm / 4s.

[0093] According to the above configuration, in the present application, only one distance measuring unit 7 is needed to obtain the moving speed of the slide 42 for analyzing when the motor speed adjustment is completed, and it can also analyze the lifting amount of the electric push cylinder 6 to allow the probe of the ultrasonic module 51 to contact the material.

[0094] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
