Description

Technical Field

[0001] The invention relates to the field of automatic cooking, and in particular to a rotary selection device, a material selection device and a material selection method. Background Art

[0002] In automatic cooking equipment, in order to ensure the flavor of the cooked ingredients, it is necessary to perform the corresponding material feeding operation at an appropriate time, and thus a rotary selection device is required to perform the corresponding material selection and feeding operation.

[0003] The current rotation selection is as shown in CN113494680A, which includes a rotation mechanism connected to an angle sensor, defining the zero position of the angle sensor as the initial position. When a selection operation is required, the corresponding selection position is determined according to the angle of the angle sensor, and the angle sensor stops after reaching the corresponding selection position. At this time, the unloading device at the corresponding selection position can be driven to perform the unloading operation. The above scheme has the following defects: the selection position is determined by the angle of the angle sensor. Once the selection position needs to be modified or changed or the selection position needs to be increased or decreased, the angle settings in the algorithm need to be updated to adapt to the position change. The adjustment is time-consuming and increases the development time. At the same time, the positioning of the selection position in this scheme relies on the angle detection of the angle sensor. If the error of the angle sensor is large, it may cause the rotation mechanism to be unable to reach the corresponding selection position, thereby requiring a high-precision angle sensor, which increases the cost. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the defects of the rotary selection device in the prior art, that is, the adjustment is complex and the cost is high, and a rotary selection device, a material selection device and a material selection method are provided.

[0005] The present invention solves the above technical problems through the following technical solutions:

[0006] A rotation selection device, comprising a rotating part, which can rotate with its center as the axis, an interference part is provided on the rotating part, and the interference part can pass through multiple selection positions when the rotating part rotates, characterized in that an initial sensing structure and multiple matching sensing structures are provided on the rotating part along the circumferential direction, and the radial relative positions of the multiple matching sensing structures respectively correspond to the selection positions, and the rotation selection device also includes a sensing device arranged beside the rotating part, when the rotating part rotates, the running paths of the initial sensing structure and the matching sensing structure can pass through the sensing area of ​​the sensing device, and the characteristic signal generated by the sensing device when sensing the initial sensing structure is different from the characteristic signal generated when sensing the matching sensing structure.

[0007] When the rotation selection device is working, the initial position is first determined by the initial sensing structure, and then the corresponding selection position is determined by the order of appearance of the matching sensing structure after the initial position. With such a structure, even if the selection position is adjusted, its position determination logic remains unchanged, and development and adjustment are easier. At the same time, the accuracy of the rotation selection device is mainly determined by the placement accuracy of the matching sensing structure, and the implementation cost is lower than that of the high-precision angle sensor used in the prior art, so it also has the advantage of low cost.

[0008] Preferably, the initial sensing structure comprises a plurality of adjacently arranged grating gaps provided on the rotating part, and the matching sensing structure comprises a single grating gap provided on the rotating part, and the grating gap can cause the sensing device to generate a characteristic signal when passing through the sensing area.

[0009] Therefore, when the initial sensing structure passes through the sensing device, the sensing device can generate three continuous electrical signals, while when the matching sensing structure passes through the sensing device, only a single electrical signal can be generated. The system can determine the initial sensing structure based on the difference in electrical signals and then determine the initial position.

[0010] Preferably, the sensing device comprises a laser and a light sensor, the laser and the light sensor are respectively arranged on the inner and outer sides of the rotating part and are arranged opposite to each other, and the sensing area is the area between the laser and the light sensor.

[0011] Therefore, when the sensing device has not passed through the grating gap, the light emitted by the laser is blocked by the annular thin wall, and the optical sensor cannot generate a signal at this time. However, when the sensing device passes through the grating gap, the laser light can pass through the grating gap and hit the optical sensor, and the optical sensor generates a signal at this time, thereby enabling the sensing device to generate an electrical signal when passing through the initial sensing structure and the matching sensing structure.

[0012] Preferably, the radial relative positions of the interference portion and one of the matching sensing structures on the rotating portion overlap with each other.

[0013] By adopting such a structure, when the interference part rotates to the selected position, the matching sensing structure can also be in a corresponding position sensed by the sensing device, so that the sensing device can send a signal to stop the rotation of the rotating part, so that the interference part accurately stays at the corresponding selected position. Since the radial relative positions of the multiple selected positions are consistent with the radial relative positions of the multiple matching sensing structures, when the interference part rotates to align with the next selected position, the next adjacent matching sensing device is also sensed by the sensing device. Therefore, the interference part can be controlled to switch between multiple selected positions by sensing the sensing position of the matching sensing structure by the sensing device.

[0014] Preferably, the matching induction structure coinciding with the radial position of the interference portion is arranged adjacent to the initial induction structure, and the initial induction structure is arranged at an upstream position of the matching induction structure opposite to the rotation direction of the rotating portion.

[0015] In this way, after the sensing device senses the initial sensing device to determine the initial position, the interference portion can rotate to the subsequent selected position more quickly, thereby improving the response speed.

[0016] Preferably, the radial relative positions of the initial sensing structure and the plurality of matching sensing structures relative to the axis of the rotating part are consistent with the radial relative positions of the selected positions relative to the axis of the rotating part, thereby enabling the material unloading operation to be performed when the annular part is in the initial position, thereby improving the material unloading efficiency.

[0017] The present invention also provides a material unloading selection device, comprising the rotary selection device as described above and multiple material unloading mechanisms, wherein the material unloading mechanisms include multiple matching parts arranged at the selection position, and the interference part in the rotary selection device can trigger the matching part when rotating to the selection position so that the material unloading mechanism performs a material unloading operation.

[0018] The above operation method has the following advantages: the operation logic is simple, and the switching of the selected position can be realized without additional signal processing. The judgment of the selected position is based on the order of the labels. Therefore, even if the selected position is adjusted during the design process, it can be directly adapted without updating the algorithm, and the design is relatively convenient. In addition, the accuracy of this rotation method is determined by the placement position of the matching sensing structure and the initial sensing structure, the accuracy is easy to control, and the cost is low.

[0019] The present invention also provides a material selection method, which is characterized in that it is applicable to the material selection device as described above, and comprises the following steps:

[0020] S10: defining an initial position of the rotating part;

[0021] S20: starting from the initial position of the rotating part, sequentially labeling the matching sensing structures along the rotation direction of the rotating part;

[0022] S30: determining a preset number according to the material unloading instruction, wherein the preset number is a matching sensing structure number corresponding to the material unloading device to be operated;

[0023] S40: The rotating part rotates from the initial position until the sensing device senses the matching sensing structure, and determines whether the label of the matching sensing structure is a preset label. If so, the rotating part stops and performs a material unloading operation. If not, the rotating part continues to rotate, and stops and performs a material unloading operation when the sensed label of the matching sensing structure is consistent with the preset label.

[0024] Preferably, the operation of labeling the matching sensing structure includes:

[0025] S21: the rotating part rotates from the initial position, the sensing device records the order of occurrence of the sensing signals, and the numbers of the matching sensing structures are the order of occurrence of the corresponding sensing signals;

[0026] S22: The rotating part rotates and returns to the initial position.

[0027] Preferably, the step of determining the initial position comprises:

[0028] S11: the rotating part rotates until the sensing device senses the initial sensing structure, and the position of the rotating part at this time is defined as the initial position.

[0029] Preferably, the rotating part further comprises the following steps before rotating from the initial position:

[0030] S41: When the rotating part is in the initial position, it is determined whether the selected position of the interference part corresponds to the unloading device to be operated. If so, the unloading operation is performed; if not, the rotating part rotates from the initial position until the sensing device senses the matching sensing structure.

[0031] In this way, the rotating part can perform the selective material unloading operation at the initial position, thereby further improving the efficiency.

[0032] The positive and progressive effects of the present invention are:

[0033] The operation logic is simple, and even if the selection position changes slightly, it can still adapt to the original algorithm, which is convenient for development;

[0034] At the same time, the accuracy of the rotation selection device is mainly determined by the placement accuracy of the matching sensing structure, and the implementation cost is lower than that of the high-precision angle sensor used in the prior art, so it also has the advantage of low cost.

[0051] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0052] Combination Figure 1 and Figure 2 The present invention provides a rotation selection device, which includes a rotating part 100, the rotating part 100 can rotate with its center as the axis, and the rotating part 100 is provided with an interference part 110, and the interference part 110 can pass through a plurality of selection positions 112 when rotating with the rotating part 100. In the present invention, the selection position 112 is located at the radial outer side of the rotating part 100. Of course, according to actual needs, the selection position 112 can also be set at the radial inner side of the rotating part 100.

[0053] The rotating part 100 is provided with an annular thin wall 120 centered on the rotation axis of the rotating part 100, and an initial sensing structure 300 and a plurality of matching sensing structures 400 are provided on the annular thin wall 120, wherein the radial relative positions between the plurality of matching sensing structures 400 respectively correspond to the selection positions 112, that is, the radial arrangement between the plurality of matching sensing structures 400 is consistent with the radial arrangement positions between the plurality of rotation positions. The rotation selection device also includes a sensing device 200 disposed beside the rotating part 100, and the sensing device 200 can sense the initial sensing structure 300 and the matching sensing structure 400 on the rotating part 100 when the rotating part 100 rotates, and the characteristic signal generated when the sensing device 200 senses the initial sensing structure 300 is different from the characteristic signal generated when the sensing device 200 senses the matching sensing structure 400.

[0054] When the rotation selection device is working, the initial position 111 is first determined by the initial sensing structure 300, and then the corresponding selection position 112 is determined by the order of appearance of the matching sensing structure 400 after the initial position 111. With such a structure, even if the selection position 112 is adjusted, its position determination logic remains unchanged, and development and adjustment are easier. At the same time, the accuracy of the rotation selection device is mainly determined by the placement accuracy of the matching sensing structure 400, and the implementation cost is lower than that of the high-precision angle sensor used in the prior art, so it also has the advantage of low cost.

[0055] In this embodiment, the initial sensing structure 300 includes a plurality of adjacently arranged grating gaps on the rotating part 100. In the present invention, the number of the grating gaps is preferably three. The matching sensing structure 400 includes a single grating gap on the rotating part 100. The sensing device 200 can generate an electrical signal when the grating gap is crossed during rotation. Thus, when the initial sensing structure 300 passes through the sensing device 200, the sensing device 200 can generate three continuous electrical signals, while when the matching sensing structure 400 passes through the sensing device 200, only a single electrical signal can be generated. The system can determine the initial sensing structure 300 based on the difference in the electrical signals, and then determine the initial position 111.

[0056] The sensing device 200 includes a laser 210 and a light sensor 220, which are arranged relative to each other and are respectively disposed on the radial inner and outer sides of the rotating part 100, specifically, on the inner and outer sides of the annular thin wall 120. Therefore, when the sensing device 200 does not pass through the grating gap, the light emitted by the laser 210 is blocked by the annular thin wall 120, and the light sensor 220 cannot generate a signal at this time. When the sensing device 200 passes through the grating gap, the light of the laser 210 can pass through the grating gap and hit the light sensor 220, and the light sensor 220 generates a signal at this time, thereby enabling the sensing device 200 to generate an electrical signal when passing through the initial sensing structure 300 and the matching sensing structure 400.

[0057] In this embodiment, the radial relative positions of the interference portion 110 and one of the matching sensing structures 400 on the rotating portion 100 overlap with each other. By adopting such a structure, when the interference portion 110 rotates to the selection position 112, the matching sensing structure 400 can also be at a position sensed by the sensing device 200, so that the sensing device 200 can send a signal to stop the rotation of the rotating portion 100, so that the interference portion 110 accurately stays at the corresponding selection position 112. Since the radial relative positions of multiple selection positions 112 are consistent with the radial relative positions of multiple matching sensing structures 400, when the interference portion 110 rotates to align with the next selection position 112, the next adjacent matching sensing device 200 is also sensed by the sensing device 200. Therefore, the interference portion 110 can be controlled to switch between multiple selection positions 112 by sensing the sensing position of the matching sensing structure 400 by the sensing device 200.

[0058] In this embodiment, the matching sensing structure 400 that coincides with the radial position of the interference part 110 is arranged adjacent to the initial sensing structure 300, and the initial sensing structure 300 is arranged at an upstream position of the matching sensing structure 400 opposite to the rotation direction of the rotating part 100. For the solution that when the sensing device 200 senses the initial sensing device 200, the interference part 110 is not at any selected position 112, such a setting can be adopted to make the interference part 110 reach the next selected position 112 at the fastest speed when the rotating part 100 starts to rotate from the initial position 111, thereby improving the operation efficiency and operation speed.

[0059] More preferably, the present invention preferably makes the radial relative position of the initial sensing structure 300 and the plurality of matching sensing structures 400 relative to the axis of the rotating part 100 consistent with the radial relative position of the selection position 112 relative to the axis of the rotating part 100. In other words, when the rotating part 100 is at the initial position 111, the interference part 110 can be at a corresponding selection position 112, so that the rotation selection device can perform the selection and blanking operation at the initial position 111, further improving the working efficiency.

[0060] Combination Figure 1 and Figure 2 The present invention also provides a material selection device, comprising the rotary selection device and a plurality of material selection mechanisms as described above, wherein the material selection mechanism comprises a matching portion 510 corresponding to the selection position 112, and the interference portion 110 in the rotary selection device can trigger the matching portion 510 when rotating to enable the material selection mechanism to perform a material selection operation. The material selection device also has the advantages of convenient adjustment and low cost.

[0061] Combination Figure 3 The present invention also provides a material selection method, which is applicable to the material selection device as above, and comprises the following steps:

[0062] S10: defining an initial position 111 of the rotating part 100;

[0063] S20: From the initial position 111 of the rotating part 100 , the matching sensing structures 400 are numbered in sequence along the rotation direction of the rotating part 100 ;

[0064] S30: determining a preset number according to the material unloading instruction, the preset number being the number of the matching sensing structure 400 corresponding to the material unloading device 500 to be operated;

[0065] S40: The rotating part 100 rotates from the initial position 111 until the sensing device 200 senses the matching sensing structure 400, and determines whether the label of the matching sensing structure 400 is a preset label. If so, the rotating part 100 stops and performs a material unloading operation. If not, the rotating part 100 continues to rotate, and stops and performs a material unloading operation when the sensed label of the matching sensing structure 400 is consistent with the preset label.

[0066] The above operation method has the following advantages: the operation logic is simple, and the switching of the selection position 112 can be realized without additional signal processing. The judgment of the selection position 112 is based on the order of the labels, so even if the selection position 112 is adjusted during the design process, it can be directly adapted without updating the algorithm, and the design is relatively convenient. In addition, the accuracy of the rotation method is determined by the placement of the matching sensing structure 400 and the initial sensing structure 300, the accuracy is easy to control, and the cost is low.

[0067] In this embodiment, the operation of labeling the matching sensing structures 400 includes:

[0068] S21: The rotating part 100 rotates from the initial position 111, and the sensing device 200 records the order of occurrence of the sensing signals. The numbers of the matching sensing structures 400 are the order of occurrence of the corresponding sensing signals.

[0069] S22 : The rotating part 100 rotates and returns to the initial position 111 .

[0070] By executing the above steps, the interference portion 110 can be placed in the initial position 111 and the labeling operation can be completed, thereby realizing the initialization of the rotation selection device.

[0071] In this embodiment, the step of determining the initial position 111 includes:

[0072] S11 : the rotating part 100 rotates until the sensing device 200 senses the initial sensing structure 300 , and the position of the rotating part 100 at this time is defined as the initial position 111 .

[0073] For the solution that when the rotating part 100 is in the initial position 111, the interference part 110 can still be in a selected position 112, it also includes the following steps:

[0074] S41: Before the rotating part 100 rotates from the initial position 111, determine whether the selected position 112 of the interference part 110 corresponds to the unloading device 500 to be operated when the rotating part 100 is in the initial position 111. If so, perform the unloading operation; if not, the rotating part 100 rotates from the initial position 111 until the sensing device 200 senses the matching sensing structure 400.

[0075] Through the above steps, the rotary unloading device 500 can perform unloading operations even when it is at the initial position 111, thereby further improving the efficiency of selective unloading.

[0076] Although the specific embodiments of the present invention are described above, it should be understood by those skilled in the art that this is only for illustration and the protection scope of the present invention is defined by the appended claims. Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but these changes and modifications all fall within the protection scope of the present invention.
