Description

[0002] Food materials, building materials, industrial substrates, etc. all need to be sliced ​​during use. When there is a large amount of cutting, if the traditional method of manually holding the knife for cutting is still used, it is relatively inconvenient, and when encountering harder objects, manual cutting is difficult; for this reason, various types of electric cutting equipment are launched on the market.

[0003] For electric slicing tools, only the motor drives the saw blade to rotate and provide cutting force, which is relatively insufficient in the current increasingly intelligent situation and lacks market competitiveness. For this reason, relevant manufacturers and R&D personnel have proposed full automation, that is: after placing the object to be cut into the equipment, the user is freed as much as possible so that the user can complete other tasks simultaneously.

[0004] To achieve the above requirements, we must first detect and control the slice thickness, and then monitor and control the feeding and cutting. At this time, if a group of corresponding component mechanisms are designed for each requirement, although the purpose can be achieved, the structural utilization rate is relatively low and the cost performance is low. Therefore, this application proposes a new technical solution. Summary of the invention

[0022] Optionally, analyzing the saw blade rotation speed based on the determined detection path and the change of the saw blade during rotation includes:

[0023] It is determined that the detection point intermittently falls on the back plate and the saw blade, and the change interval is inversely proportional to the rotation speed of the saw blade. The rotation speed of the saw blade is calculated based on the change interval.

[0024] Optionally, the analysis of the slice start node and the single slice end node includes:

[0053] The following is combined with Figure 1-2 This application is described in further detail.

[0054] The embodiment of the present application discloses a slice thickness monitoring method.

[0055] Reference Figure 1 The slice thickness monitoring method is based on the electric slicing device. In this embodiment, food slicing is taken as an example for detailed description.

[0056] Methods include:

[0057] Step 1: Establish a perception mechanism; and,

[0058] Step 2: Establish one-to-three analysis logic.

[0059] Referring to the figure, the electric slicing device should have basic electric cutting and feeding functions. It should be noted that slicing is often to cut the object to be cut into multiple pieces, so it is a reciprocating feeding form. Therefore, the structure should at least have:

[0060] A back plate, serving as a support and capable of being driven in the thickness direction by an electric linear actuator;

[0061] The saw blade, driven by a motor, serves as the execution unit of slicing;

[0062] The pusher is opposite to the back plate and serves as a structure for pressing the object to be cut. It drives the object to be cut to move back and forth under the drive of another corresponding electric linear drive mechanism.

[0063] The above is the prior art and is only used as a basis, so it will not be repeated here.

[0064] Regarding step 1, establishing a perception mechanism, it includes:

[0065] 11) The side of the back plate supporting the electric slicing device is defined as the front side, the saw blade is located on the front side of the back plate and is arranged parallel to each other, and one end of the back plate overlaps with the edge of the saw blade in a front-view posture, that is, a slicing space is formed between the two, and the vertical distance between the two is the slicing thickness.

[0066] The front side of the back plate fixes the object to be cut by a pusher, and the pusher reciprocates along the length direction of the back plate.

[0067] 12) Detect the back plate in an inclined ranging posture, and make the detection path intersect with the saw blade. The detection point is on the back plate and saw blade, close to the edge of the saw blade.

[0068] The above detection can use: laser ranging sensors, ultrasonic detection sensors, etc. In this embodiment, laser ranging sensors are preferred, which will be explained in detail later.

[0069] 13) A non-contact response structure 1 is added to the detection landing point of the back plate, and an excitation structure 2 for triggering the non-contact response structure is added to the tail end of the pusher; wherein the tail end of the pusher is outside the end of the fixed object to be cut away from the saw blade, so as to achieve the requirement of triggering the excitation structure 2 after completing each cutting action.

[0070] Regarding step 2, establish the one-to-three analysis logic, which includes:

[0071] 21) Based on the determined detection path and the angle between the detection path and the saw blade, the slice thickness is analyzed and calculated.

[0072] Specifically:

[0073] 21.1) The starting point of the detection is obtained from the detection path, which is recorded as point a, and the detection landing point is recorded as point b. It can be understood that it has been said above that the detection landing point is on the saw blade and the back plate, so the saw blade should be intermittently opened with detection holes around the center, corresponding to:

[0074] When no cutting occurs, the detection landing points appear regularly on the saw blade and the back plate, generating two regularly appearing detection values, with the larger one being point b on the back plate and the smaller one being point b on the saw blade.

[0075] The larger value is recorded as L1, and the other value is recorded as L2. L1-L2 gives the detection path length L3 between the saw blade and the back plate.

[0076] 21.2) The detection path is fixed, and the angle between the detection path and the saw blade is fixed, denoted as β;

[0077] The slice thickness can be calculated according to the trigonometric function and L3, specifically: sinβ=d / L3, where d is the slice thickness.

[0078] 22) Based on the determined detection path and the changes in the saw blade during rotation, the saw blade rotation speed is analyzed.

[0079] As mentioned above, there are detection holes on the saw blade to allow the detection path to pass through the saw blade landing point to the back plate. Therefore, when the saw blade starts to rotate, the detection path passes through intermittently, and the interval is inversely proportional to the rotation speed of the saw blade, that is, the faster the rotation speed, the smaller the interval; and the detection path is fixed, so the rotation speed of the saw blade can be calculated based on the landing point change interval (frequency) of the detection path.

[0080] Example: There are 3 through holes to be detected, with an interval of 120°. The saw blade rotates one circle in 1 second, and the landing point changes 6 times in 1 second. If it changes 60 times in 1 second, the rotation speed is 10 circles / s.

[0081] This function is derived from the detection condition of slice thickness.

[0082] 23) Based on the determined detection path and saw blade rotation parameters, analyze the slicing start node.

[0083] It can be understood that, based on the above, if the saw blade does not cut the object to be cut, the landing point of the detection path is either on the saw blade or on the back plate, but once the object to be cut is pushed to contact the saw blade, the landing point of the detection path will appear on the object to be cut, therefore:

[0084] If the saw blade rotation parameter indicates that the rotation is maintained, and the landing point of the detection path changes from two positions to a third or more positions, the current moment is determined to be the slicing start node.

[0085] Based on the changes of the non-contact response structure after the slice start node, the single slice end node is analyzed.

[0086] It can be understood that the non-contact response structure will be triggered by the excitation structure, and according to the function of the pusher, before the cutting action is completed, the excitation structure will not face the non-contact response structure, so it will not be triggered. Therefore, the non-contact response structure will produce different outputs as feedback when the pusher pushes the object to be cut to complete a slicing action. Therefore, the output of the non-contact response structure can determine the end node of a single slicing.

[0087] The slice start node and the single slice end node are grouped, and the slice start node is obtained based on the derived analysis of the detection path.

[0088] 24) Based on the analysis results, slice thickness control, saw blade variable speed energy-saving control and pusher variable stroke energy-saving control are performed.

[0089] Among them, the slice thickness control includes: calculating the thickness adjustment amount according to the user's slice demand and the calculated real-time slice thickness, and controlling the movement of the back plate according to the thickness adjustment amount.

[0090] According to the above settings, the slicing device can display approximate pictures and other information on the display screen, allowing the user to select their own needs, and then automatically and accurately complete the slice thickness adjustment.

[0091] Regarding the variable speed energy-saving control of saw blades, it includes:

[0092] Speed ​​1 is defined as the speed when cutting an object, and speed 2 is defined as the speed when idling, and speed 1 is greater than speed 2; speed 1 and speed 2 are both preset values;

[0093] If the saw blade is started, the saw blade is controlled to rotate at speed 2;

[0094] If the current node is the starting node of slicing, the saw blade is controlled to rotate at a speed of one;

[0095] If the current node is the end of a single slice, the saw blade is controlled to rotate at a speed of two.

[0096] According to the above arrangement, the saw blade no longer rotates at a fixed speed as in the traditional method, so as to reduce energy consumption and wear; especially when the size of the slices of the object to be cut gradually changes, the idling loss is reduced.

[0097] Regarding the variable stroke energy-saving control of the pusher, it includes:

[0098] Define the starting node of the next slice after the end node of a single slice as the retraction point, and record the coordinates of the retraction point as (x1,0);

[0099] The pusher is controlled to move toward the saw blade again at the coordinate (x1+x2,0); wherein x2 is a preset value used to prevent incomplete retraction from affecting the next slicing.

[0100] It can be understood that the above coordinates are generated in a plane coordinate system, and the X-axis direction is the moving direction of the pusher; according to the above settings, no matter how far the object to be cut is from the saw blade at the beginning or whether it is regular, after the slicing starts, the position of each retraction will be updated in real time at a position close to the x2 value from the saw blade, which ensures the smooth progress of the next slicing and prevents the retraction distance from being too far, thereby improving the slicing efficiency and reducing unnecessary reciprocating movement.

[0101] In summary, this method can analyze the slice thickness based on the detection path of the tilt posture, which is convenient for automatic adjustment of the slice thickness; at the same time, through the relationship between the detection path and the saw blade, the speed of the saw blade and the starting node of the slice can be further analyzed;

[0102] On the basis of the above, the end node of a single slice is analyzed by simply adding a non-contact response structure in the second half of the slicing process;

[0103] Afterwards, by utilizing the start node of group slicing and the end node of single slicing, the saw blade speed can be obtained in real time, so that the saw blade can be fast when it should be fast and slow when it should be slow, and the saw blade variable speed energy-saving control can be performed to reduce energy consumption;

[0104] By analyzing the cycle characteristics of the slicing start node and the single slicing end node, the relatively optimal stop point for each retraction is determined, so that no matter how far the object to be cut is from the saw blade at the beginning or whether it is regular, after the slicing starts, the position of each retraction will be updated in real time to a position close to the value of x2 from the saw blade, which ensures the smooth progress of the next slicing and prevents the retraction distance from being too far, thereby improving the slicing efficiency and reducing unnecessary reciprocating movement;

[0105] In summary, this method can realize the feasibility of one-to-three or even more functions based on slice thickness detection, which can improve the structural utilization rate of the slicing equipment and improve the cost performance.

[0106] Reference Figure 2 In another embodiment of the method, in order to reduce the situation where the detection through hole on the saw blade is accidentally blocked and causes misjudgment, the method further includes: establishing an error suppression mechanism, which includes:

[0107] A follower plate 3 and a return spring 4 are provided, so that the follower plate 3 is pushed away and the spring 4 is compressed after the pusher moves toward the saw blade; wherein the follower plate 3 is located at the outer end of the moving path of the pusher, and is slidably connected to the mounting structure of the saw blade, and the sliding direction is parallel to the pusher; one end of the return spring 4 is fixed to the follower plate 3, and the other end is fixed to the mounting structure of the saw blade.

[0108] A nozzle 5 is arranged on the follower plate 3, and the nozzle 5 moves toward the detection through hole when the follower plate 3 is not pushed by the pusher;

[0109] The air source / water source unit is connected to the nozzle 5; for example, a small air pump is connected via an air pipe.

[0110] According to the above arrangement, after each slicing is completed, the nozzle 5 can blow air toward the detection through hole; it can be understood that the faster the air flow speed, the better the effect.

[0111] Based on the above foundation, the laser distance measuring sensor for inclined distance measurement can be installed on the follower plate 3, located on the side of the nozzle 5 away from the pusher; or on another fixed bracket on the side of the follower plate 3 away from the saw blade, and the nozzle is located on the side of the laser distance measuring sensor away from the pusher, and is inclined toward the detection through hole.

[0112] The above structure is an optional structure. Generally speaking, a high-speed rotary saw blade will not cause the tissue of the object to be cut to get stuck in the detection through hole, unless the coagulation degree of the object to be cut is low and it is relatively easy to collapse and deform.

[0113] In another embodiment of the present application, the non-contact response structure 1 is a photoconductive effect unit, such as a phototransistor, which is installed in an embedded manner and is flush with the back plate or with a high-transmittance film.

[0114] Correspondingly, the excitation structure 2 is now a lamp group, for example, a miniature spotlight, which can direct a light beam toward the phototransistor to change the electrical signal output by the phototransistor.

[0115] It can be understood that the method involves automation and requires a controller, so the non-contact response structure 1 and the excitation structure 2 mentioned above can be connected to the controller.

[0116] Because the light trigger is used here, there is a problem: if the excitation structure 2 is covered by the residue of the object to be cut, interference will occur. For this reason, the error suppression mechanism is established, which also includes:

[0117] A scraper 6 is provided, which may be a rubber plate, and is connected to the rear end of the pusher through a bracket; the scraper 6 is located on a side of the excitation structure 2 close to the saw blade, and the scraper 6 contacts the back plate.

[0118] According to the above arrangement, before the excitation structure 2 triggers the non-contact response structure 1, a scraping operation is first performed on the back plate to ensure the normal use of the phototransistor.

[0119] In another embodiment of the present application, the above-mentioned non-contact response structure 1 and excitation structure 2 can be a magnetic induction switch and a permanent magnet. In this case, the two are triggered by magnetic induction, and there is no need to consider the influence of residues on the back plate. However, it should be noted that adjacent structures and objects to be cut should not have magnetic or magnetizable properties, and the accuracy is slightly inferior to the previous method.

[0120] The embodiment of the present application also discloses a slicing device.

[0121] Reference Figure 1 , a slicing device, which applies any of the methods described above on an electric slicing structure.

[0122] 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.
