Description

Technical Field

[0001] This invention relates to the field of feeding device technology, and more specifically, to a control method and a feeding device opening and closing door structure. Background Technology

[0002] When existing feeding devices use a centralized discharge port for solid materials, powders, and other materials, a unified sealing structure is generally used at multiple discharge ports to manage the opening and closing of the discharge ports in order to concentrate the feeding at one point. While this structure allows for unified management of the discharge ports, it presents two drawbacks when only one or more materials (not all) need to be discharged. First, the inevitable vibrations at the discharging port can cause some of the materials that don't need to be discharged to fall out due to vibration or inherent instability, leading to mixing. If the powder is a seasoning, this affects the taste and appearance of food; if it's a medicine, it affects its efficacy. Second, materials like seasonings and medicines often require sealing to prevent moisture. Opening the corresponding discharge port even when not discharging increases the exposure time and frequency to air, making the materials susceptible to moisture, affecting discharging accuracy, and potentially causing blockages. Third, frequently opening the discharge port makes the materials more prone to contamination and hinders cleaning. Summary of the Invention

[0003] The main objective of this invention is to provide a control method and a structure for opening and closing the door of a feeding device, so as to solve the problems of material mixing, sealing against moisture, or cleaning in the prior art.

[0004] To achieve the above objectives, according to one aspect of the present invention, a control method for the opening and closing structure of a feeding device is provided, comprising: a selection drive mechanism receiving an instruction, a drive end changing position under the drive of the selection drive mechanism, at least one drive end moving to one or more preset open opening and closing doors, and the remaining drive ends remaining stationary or moving to a position offset from a preset closed opening and closing door; and a push mechanism receiving an instruction to actuate the push mechanism so that the selection drive mechanism moves with the push mechanism, and the preset open opening and closing door is opened under the action of its corresponding drive end.

[0005] Furthermore, the control method also includes: when the drive end changes position under the drive of the selected drive mechanism, multiple drive ends sequentially abut against each other in their arrangement order to achieve synchronous rotation. All drive ends include a first drive end, a second drive end, a third drive end, ..., an nth drive end, ..., an Nth drive end in sequence, where n ≤ N. The nth drive end is the drive end that needs to change position and is the farthest from the first drive end. The control method also includes: when the drive end changes position under the drive of the selected drive mechanism, the first drive end rotates along a first direction and abuts against the second drive end, causing the second drive end to rotate together; the second drive end rotates and abuts against the third drive end, causing the third drive end to rotate... the (n-1)th drive end rotates and abuts against the nth drive end, causing the nth drive end to rotate; after the nth drive end rotates to a predetermined position, the first drive end rotates along a first direction and abuts against the second drive end, causing the second drive end to rotate together; the second drive end rotates and abuts against the third drive end, causing the third drive end to rotate... the (n-1)th drive end rotates and abuts against the nth drive end, causing the nth drive end to rotate; after the nth drive end rotates to a predetermined position, the first drive end rotates along a first direction and abuts against the second drive end, causing the second drive end to rotate together. The first driving end rotates in the opposite direction to the second driving end, separating from the second driving end until the first driving end rotates along the second direction to the other side of the second driving end and comes into contact with the second driving end, causing the second driving end to rotate together. After the second driving end rotates, it first separates from the third driving end, then rotates to the other side of the third driving end and comes into contact with the third driving end, causing the third driving end to rotate together... After the (n-2)th rotation, it first separates from the (n-1)th driving end, then rotates to the other side of the (n-1)th driving end and comes into contact with the (n-1)th driving end, causing the (n-1)th driving end to rotate together. After the (n-1)th driving end rotates, it separates from the nth driving end. The above two steps alternate, with the first driving end rotating alternately along the first and second directions in sequence, and changing the position of the driving end in the order of the nth driving end, the (n-1)th driving end..., the second driving end.

[0006] Furthermore, the control method also includes: before the first drive end rotates along the first direction, the detection element detects the position of each drive end. Among all drive ends, the drive end not located at a preset open door, the drive end located at a preset closed door, and when all drive ends are respectively located at preset open doors or not located at preset closed doors, and not all preset open doors have drive ends, at least one of the multiple drive ends located at the same preset open door, the drive end with the longest driving distance from the first drive end among all the above drive ends is designated as the nth drive end.

[0007] Furthermore, the number of preset open doors is m, and the number of all drive ends is N. The control method also includes: when m = N, all drive ends move to each preset open door; when m < N, the first drive end, the second drive end, ..., the mth drive end move to each preset open door, or the second drive end, the third drive end, ..., the (m+1)th drive end move to each preset open door.

[0008] Furthermore, the control method also includes: when the drive end changes position under the drive of the selected drive mechanism, each drive end abuts in sequence, the first drive end drives all drive ends to rotate to a preset open door position, and then the first drive end rotates alternately along the first direction and the second direction in sequence, and changes the position of the drive end in the order of the (n-1)th drive end... and the second drive end.

[0009] Furthermore, the control method also includes: after the preset openable door is opened to complete the unloading, the push mechanism receives the instruction, pushes the mechanism to move, and all openable doors are closed under the action of the push mechanism.

[0010] Furthermore, the control method also includes: after the preset open door is opened to complete the unloading or before the unloading begins, the selected drive mechanism receives the instruction, and the drive end is reset to the initial state under the drive of the selected drive mechanism. In the initial state, all drive ends are staggered from all open doors, or at least one drive end moves to the open door.

[0011] Furthermore, the control method also includes: the material feeding device opening and closing structure starts to operate after receiving a first user instruction; or the material feeding device opening and closing structure does not operate when receiving a first user instruction, but starts to operate after receiving a second user instruction; wherein, the first user instruction includes the material type, and the second user instruction includes confirming material feeding.

[0012] According to another aspect of the present invention, a feeding device opening and closing door structure is provided, comprising: a main support having a feeding channel for feeding and a plurality of feeding ports communicating with the feeding channel; a plurality of opening and closing doors movably connected to the main support and capable of opening or closing the feeding ports; a selection drive mechanism having a plurality of drive ends movably configured, the drive ends being switchable between a position driving and engaging with the opening and closing doors and a position driving and disengaging from the opening and closing doors, all drive ends being selectively driving and engaging with preset open opening and closing doors; and a pushing mechanism connected to the selection drive mechanism, the pushing mechanism being capable of driving the selection drive mechanism to move and driving the opening and closing doors driving and engaging with the drive ends to move, so as to open the corresponding opening and closing doors.

[0013] Furthermore, the number of drive ends is greater than or equal to the number of opening and closing doors; multiple opening and closing doors are arranged sequentially around the circumference of the feeding channel, and at least a portion of the selected drive mechanism is rotatably configured; when at least a portion of the selected drive mechanism rotates, two adjacent drive ends abut against each other in the circumference of the feeding channel and rotate synchronously, or at least one of the two adjacent drive ends rotates in a direction away from the abutment direction of the two to separate the two.

[0014] Furthermore, when at least a portion of the selected drive mechanism rotates in the first direction, multiple drive ends sequentially abut against each other; when at least a portion of the selected drive mechanism rotates in the second direction, multiple drive ends in the abutting state sequentially separate; wherein the first direction and the second direction are opposite.

[0015] Furthermore, the selection drive mechanism includes: a drive element; a main selection ring, which is drivenly connected to the drive element; and a slave selection ring, both of which have drive ends. The drive end of the main selection ring is the active end, and the drive end of the slave selection ring is the driven end. The driven end is located on the movement path of the active end. When the main selection ring rotates, the active end pushes the driven end to rotate, thereby causing each driven end to switch between a position that is connected to the door opening / closing drive that needs to be opened and a position that is separated from the door opening / closing drive.

[0016] Furthermore, the selector ring is stacked with the main selector ring, with the driving end and the driven end located at the circumferential edges of the main selector ring and the selector ring, respectively. Along the axial direction of the selection drive mechanism, the thickness of the driven end is greater than the thickness of the selector ring.

[0017] Furthermore, the driven end of the slave selection ring, which is stacked and attached to the main selection ring, extends into the peripheral edge of the main selection ring. There are multiple slave selection rings. When multiple slave selection rings are stacked, in two adjacent slave selection rings, the driven end of the slave selection ring farther from the main selection ring extends into the peripheral edge of the slave selection ring closer to the main selection ring.

[0018] Furthermore, the selector ring is located on the side of the main selector ring facing the drive member, and at least a portion of the opening / closing door is located between the selector ring and the drive member. The top of the opening / closing door has a radially extending protruding end. When the drive end is driven to engage with the opening / closing door, the protruding end is located on the movement path of the drive end. When the drive end moves along the extension direction of the feeding channel, it drives the opening / closing door to open through the protruding end. When the drive end is separated from the opening / closing door, the drive end avoids the protruding end. When the drive end moves along the extension direction of the feeding channel, the opening / closing door remains closed.

[0019] Furthermore, the drive mechanism also includes a closing structure, which is connected to and moves synchronously with the push mechanism. The closing structure has a closing surface at one end facing the opening and closing door, and at least a portion of the opening and closing door is located between the closing surface and the drive end. When the push mechanism moves toward the material discharge channel, the closing surface abuts against the opening and closing door and pushes the opening and closing door to close.

[0020] By applying the technical solution of this invention, the driving end of the selected driving mechanism changes position, and the driving end cooperates with the opening and closing doors according to their opening and closing requirements. The driving end engages with the preset open opening door and is staggered with the preset closed opening door. Thus, when the pushing mechanism moves, causing the selected driving mechanism to move together, the driving end can open the preset open opening door, while the preset closed opening door remains closed due to the lack of driving force. This achieves the simultaneous opening and closing of doors that need to be opened and closed. Even if there are factors such as vibration during feeding of the open opening door or instability of the seasoning itself, the closed opening door cannot feed, thus avoiding mixing of seasonings that do not need to be fed, ensuring the purity of the fed materials, and achieving the desired taste and appearance in food and the efficacy in pharmaceuticals. It also prevents unnecessary seasonings from being repeatedly exposed to air, causing them to become damp or even clump and clog. Furthermore, the seasonings are less susceptible to external contamination, ensuring their cleanliness. Attached Figure Description

[0031] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0033] In this invention, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not intended to limit this invention.

[0034] To address the problems of material mixing, sealing against moisture, or cleaning issues in existing feeding devices, this invention provides a control method and a feeding device opening / closing door structure.

[0035] The control method for the opening and closing structure of the feeding device in this embodiment includes: a selection drive mechanism 30 receiving an instruction, a drive end 31 changing position under the drive of the selection drive mechanism 30, at least one drive end 31 moving to one or more preset open opening and closing doors 20, and the remaining drive ends 31 remaining stationary or moving to a position offset from the preset closed opening and closing doors 20; a push mechanism 40 receiving an instruction, actuating the push mechanism 40 so that the selection drive mechanism 30 moves with the push mechanism 40, and the preset open opening and closing door 20 is opened under the action of its corresponding drive end 31.

[0036] In this embodiment, the drive mechanism 30 drives the drive end 31 to change position. The drive end 31 cooperates with the opening and closing doors 20 according to their opening and closing requirements. The drive end 31 is connected to the preset open opening door 20 and staggered with the preset closed opening door. In this way, when the push mechanism 40 moves and drives the drive mechanism 30 to move together, the drive end 31 can drive the preset open opening door 20 to open, while the preset closed opening door 20 remains closed because it is not driven by the drive end 31. This achieves the simultaneous opening and closing of the opening door 20 that needs to be opened and the closing door 20 that needs to be closed. Even if there are factors such as vibration when the feeding mechanism corresponding to the open opening door 20 is feeding or instability of the seasoning itself, the closed opening door 20 cannot feed, thereby avoiding the mixing of seasonings that do not need to be fed together and ensuring the purity of the fed materials. This achieves the effects of ensuring taste and appearance in food and ensuring efficacy in medicine. It also prevents seasonings that do not need to be added from being exposed to the air multiple times, which can cause them to become damp or even clump and clog. In addition, the seasonings are less susceptible to external contamination, ensuring their cleanliness.

[0037] The control method for the opening and closing structure of the feeding device in this embodiment, as well as the opening and closing structure itself, can be applied to seasonings, powders, and other types of materials. This embodiment uses seasonings as an example for explanation.

[0038] When the drive mechanism 30 drives the drive end 31 to operate, there may be one or more preset open doors 20. When there is only one, there may be one or more drive ends 31, with at least one drive end 31 engaging with it. When there are multiple, there are also multiple drive ends 31, with each door 20 having at least one drive end 31 engaging with it, thus ensuring that all preset open doors 20 are opened. Correspondingly, when all preset open doors 20 have drive ends 31 engaged, there may be some remaining drive ends 31. If these drive ends 31 are already offset from preset closed doors 20, they can remain stationary. However, if there are drive ends 31 aligned with preset closed doors 20, these aligned drive ends 31 need to move to a position offset from the preset closed doors 20, thus ensuring that all preset closed doors 20 remain closed.

[0039] In this embodiment, to coordinate with the multiple opening and closing doors 20, multiple drive ends 31 are provided, and each drive end 31 is driven sequentially. Specifically, the control method further includes: when the drive end 31 changes position under the drive of the selected drive mechanism 30, the multiple drive ends 31 sequentially abut against each other in the order of their arrangement to achieve synchronous rotation. It should be noted that the specific structure and driving method of the selected drive mechanism 30 are not limited to the content of this embodiment. In addition to the sequential abutment driving method of the drive ends 31, other structural forms can also be adopted, such as using multiple grippers as drive ends 31 to cooperate with each opening and closing door 20, with the grippers being independent and not interfering with each other.

[0040] To facilitate the explanation of the specific operation of the drive end 31, this embodiment names all drive ends 31 sequentially according to their driving order. The terms "front" and "back" refer to the direction of drive transmission, with the end closer to the active side being "front" and the end farther from the active side being "back." Thus, all drive ends 31 include, from front to back, the first drive end, the second drive end, the third drive end, ..., the nth drive end, ..., the Nth drive end. The total number of drive ends 31 is N. The Nth drive end is the drive end 31 at the end of the drive process; the nth drive end is the middle drive end 31, where n ≤ N, and the nth drive end is the drive end 31 that needs to change position and is furthest from the first drive end. The reason for using the above definition for the nth driving end is to consider that some driving ends 31 may not need to operate. According to the sequential driving method, if one driving end 31 needs to operate, all driving ends 31 before it need to operate. Therefore, if the nth driving end needs to operate, all driving ends 31 before it need to operate, regardless of whether their positions are in place. However, all driving ends 31 after the nth driving end do not need to operate. In this way, the nth driving end is used as the boundary to divide the part that needs to operate and the part that does not need to operate.

[0041] According to the above division, the control method also includes: the specific action process of the drive end 31 changing position under the drive of the selected drive mechanism 30 is as follows: after the first drive end rotates along the first direction, it abuts against the second drive end and drives the second drive end to rotate together; after the second drive end rotates, it abuts against the third drive end and drives the third drive end to rotate... and so on, each drive end 31 abuts against the drive in sequence until the (n-1)th drive end rotates and abuts against the nth drive end and drives the nth drive end to rotate. In this way, the driving force of the first drive end can be transmitted to the nth drive end in sequence. After the nth driving end rotates to the predetermined position, the first driving end no longer rotates in the first direction, but rotates in the second direction opposite to the first direction. At this time, the first driving end separates from the second driving end until the first driving end rotates in the second direction to the other side of the second driving end and abuts against the second driving end, causing the second driving end to rotate together. After the second driving end rotates, it first separates from the third driving end, and then rotates to the other side of the third driving end and abuts against the third driving end, causing the third driving end to rotate together... and so on. Each driving end 31 abuts against and rotates in the opposite direction in sequence until the (n-2)th driving end rotates and first separates from the (n-1)th driving end, and then rotates to the other side of the (n-1)th driving end and abuts against the (n-1)th driving end, causing the (n-1)th driving end to rotate together. After the (n-1)th driving end rotates, it separates from the nth driving end and rotates to the predetermined position. Since the position of the nth driving end has been changed, the (n-1)th driving end can rotate to the position and no longer drive the nth driving end to rotate.

[0042] The above two actions alternate, with the first driving end rotating alternately along the first and second directions in sequence, and changing the position of the driving end 31 in the order of the nth driving end, the (n-1)th driving end, ..., the second driving end, so that each driving end 31 completes the position adjustment in the driving order from back to front.

[0043] In this embodiment, the control method further includes: during the rotation of the drive end 31, the detection element detects the rotation angle of the drive end 31 or the operating state of the selected drive mechanism 30, and feeds it back to the control terminal. The control terminal determines the state of the opening and closing structure of the unloading device based on the information fed back by the detection element. Therefore, during the rotation of the drive end 31, the specific rotation position can be controlled by setting a detection element to detect the rotation angle position of each drive end 31, and the control terminal performs corresponding control based on the detected information. The detection element can be a photoelectric sensor, reed switch, angle encoder, or other components. For example, taking the first driving end driving the second driving end to rotate to a predetermined position as an example, the first driving end starts to rotate under the drive of the selection driving mechanism 30. The first driving end abuts against the second driving end, causing the second driving end to rotate synchronously. During the rotation of the second driving end, the detection element detects the rotation position of the second driving end in real time. When the second driving end rotates to the predetermined position, the detection element sends a signal to the selection driving mechanism 30. The selection driving mechanism 30 receives the signal and controls the first driving end to stop rotating, and the second driving end rotates to the predetermined position. Alternatively, the detection can be performed at the predetermined position. When the second driving end is detected to have rotated to the predetermined position, the first driving end stops rotating. The motion detection of other driving ends 31 can be set according to the above.

[0044] In addition to the above-mentioned detection through the test piece, the drive component 32 of the selected drive mechanism 30 can also be a component that can be accurately controlled, such as a stepper motor. Since the positions of each opening and closing door 20 and each drive end 31 are already determined during processing and assembly, the rotation angle of each drive end 31 can be preset, and the rotation angle of the drive end 31 can be precisely controlled by the stepper motor to achieve the effect of each drive end 31 rotating into place.

[0045] In this embodiment, since there are various feeding situations, the specific requirements for the nth drive end differ depending on the feeding situation. Therefore, the nth drive end needs to be determined before rotation. The control method further includes: before the first drive end rotates along the first direction, the detection element detects the position of each drive end 31. Among all drive ends 31, there are three situations for different positions of the drive ends 31: First, the drive end 31 that is not located at the preset open door 20 is one of the drive ends 31 that needs to be activated; Second, the drive end 31 that is located at the preset closed door 20 is also one of the drive ends 31 that needs to be activated; Third, when all drive ends 31 are located at the preset open door 20 or not located at the preset closed door 20, and not all the preset open doors 20 are... When there are drive ends 31 at all 0 locations, it means that some drive ends 31 may overlap at the same preset open door 20. Some preset open door 20 does not cooperate with the drive ends 31. Therefore, at least one of the multiple drive ends 31 located at the same preset open door 20 is also one of the drive ends 31 that need to be activated. Among all the drive ends 31 that need to be activated in the above three situations, the drive end 31 that is furthest from the first drive end, that is, the drive end 31 that is closest to the end of the drive, is the nth drive end. All drive ends 31 before the nth drive end will be activated.

[0046] Optionally, the number of pre-set open doors 20 is m, and the number of all drive ends 31 is N. The control method also includes:

[0047] When m = N, it means that the number of preset opening and closing doors 20 is the same as the number of driving ends 31. At this time, all driving ends 31 move to each preset open opening and closing door 20, and each driving end 31 corresponds to and cooperates with the preset open opening and closing door 20.

[0048] When m < N, it indicates that the number of drive ends 31 is greater than the preset number of open doors 20. In this case, only some drive ends 31 may operate. Based on the driving method described above in this embodiment, it is preferable that the drive ends 31 at the front end operate, while the drive ends 31 at the rear end remain stationary at a position offset from the open doors 20. That is, the first drive end, the second drive end, ..., the mth drive end move to each preset open door 20, and the drive ends 31 after the mth drive end remain in the initial state of being offset from all open doors 20. Alternatively, since the first drive end is the very front end of the drive transmission, it may only play a transmission role and not a role in cooperating with the open doors 20. In this case, the second drive end, the third drive end, ..., the (m+1)th drive end move to each preset open door 20 and cooperate with the preset open door 20 to open the door. In this way, the front end operates while the rear end does not, thereby reducing the complexity and time required for the operation process and improving the efficiency of the operation.

[0049] It should be noted that the drive end 31 corresponding to a preset open door 20 can be one, that is, m drive ends 31 cooperate with m doors 20, or multiple drive ends 31 cooperate with the same door 20. Specifically, in another embodiment, the control method further includes: when the drive end 31 changes position under the drive of the selected drive mechanism 30, each drive end 31 abuts in sequence. The first drive end drives all drive ends 31 to rotate to a preset open door 20. Then the first drive end rotates alternately along the first direction and the second direction in sequence, and changes the position of the drive end 31 in the order of the (n-1)th drive end, ..., the second drive end. In this way, the nth drive end and the drive ends 31 thereafter are all located at the same door 20. The drive ends 31 before it change position accordingly to cooperate with other doors 20, which can also achieve the effect of the preset open door 20 opening and the preset closed door 20 remaining closed. Moreover, this method does not require the position of each drive end 31 to be detected before the action, which is more convenient. For a specific example, if only one of the opening and closing doors 20 needs to be opened, the first drive end can directly drive all the drive ends 31 to move to that opening and closing door 20. At this time, the condition that there is a drive end 31 at the opening and closing door 20 that needs to be opened and there is no drive end 31 at the opening and closing door 20 that needs to be closed can still be achieved.

[0050] Preferably, in order to avoid waste and ensure that all opening and closing doors 20 can be opened at the same time, the number of drive end 31 and opening and closing doors 20 can be set to be the same.

[0051] In this embodiment, the control method further includes: after the preset open door 20 has opened, a feeding signal is sent to the feeding mechanism. The feeding mechanism receives the signal and feeds the material. After feeding, the feeding mechanism sends a command signal to the pushing mechanism 40, indicating that the preset open door 20 has been opened and feeding has been completed. The pushing mechanism 40 receives the command and moves. All doors 20, whether open or closed, are closed by the action of the pushing mechanism 40. After the pushing mechanism 40 closes the door according to the preset stroke, it reverses its movement to reset.

[0052] Similar to the above, the control method also includes: after the preset open door 20 has been opened and the material has been unloaded, or before the material unloading begins, the selection drive mechanism 30 also receives an instruction, and the drive end 31 is reset to the initial state under the drive of the selection drive mechanism 30. The initial state can be set differently depending on the classification method. Specifically, in terms of the cooperation between the drive end 31 and the open door 20, the initial state can be that all drive ends 31 are staggered from all open doors 20, or the initial state can be that at least one drive end 31 moves to the open door 20; for each drive end 31, the initial state can be that each drive end 31 is in sequence contact, or it can be in a separated state; for the overall state, it can be returned to a fixed position, or it can be based on feeding habits or big data. For example, if it is found that a user has fed a certain seasoning the most times within a certain period of time, the return position can be automatically adjusted to the corresponding position, making it faster to open the door when unloading next time. In addition to the above settings, the initial state can also be other states. In short, the initial state can be set according to the actual situation.

[0053] The order of action of the drive mechanism 30 reset and the push mechanism 40 door closing reset can be set as needed. It can be that the push mechanism 40 performs the door closing reset first, and then the drive mechanism 30 is reset, or the drive mechanism 30 is reset simultaneously during the door closing reset process of the push mechanism 40.

[0054] Of course, the drive mechanism 30 can also be left unreset, keeping the positions of each drive end 31 unchanged after one feeding, and then adjusting it for the next feeding.

[0055] In this embodiment, the control method further includes a detection phase before the selected drive mechanism 30 receives the instruction. The detection phase includes: a detection element detecting the position of each drive end 31. When all drive ends 31 are respectively located at the preset open door 20 or none are located at the preset closed door 20, and all preset open door 20s have drive ends 31, it indicates that all drive ends 31 have moved into position. At this time, the selected drive mechanism 30 does not receive the instruction, all drive ends 31 do not move, and the pushing mechanism 40 receives the instruction to open the preset open door 20. If the above conditions are not met, it indicates that some drive ends 31 have not moved into position. At this time, the selected drive mechanism 30 receives the instruction, and the selected drive mechanism 30 needs to drive the drive ends 31 to change position according to the aforementioned action process.

[0056] In this embodiment, the control method further includes: the feeding device opening and closing door structure starts to operate after receiving a first user instruction; or the feeding device opening and closing door structure does not operate when receiving the first user instruction, but starts to operate after receiving a second user instruction; wherein, the first user instruction includes the material type, and the second user instruction includes confirming feeding. Specifically, in the first method, the user clicks the screen to select the seasoning type, selects the drive mechanism 30 to start operating, drives the drive end 31 to move to the corresponding position, and then the user clicks the feeding button to confirm feeding. If the detection component detects that the preset open and close doors 20 are all cooperated with by the drive end 31, then the opening push mechanism 40 is activated to open the open and close doors 20 for feeding. This method can save feeding time. In the second method, the user clicks the screen to select the seasoning type, at which time the drive mechanism 30 is not activated. Then, after the user clicks the feeding button to confirm feeding, the drive mechanism 30 is activated again. This can avoid the situation where the user selects the seasoning type and then cancels or changes it, resulting in re-operation.

[0057] To make it easier to understand, here is a practical example:

[0058] There are five doors 20, numbered 1, 2, 3, 4 and 5, which correspond to five seasonings: salt, sugar, chicken bouillon, pepper and chili powder.

[0059] The following situations may occur:

[0060] 1. When only one type of salt is added, if the initial state of the drive end 31 is exactly at door 1, and the other drive ends 31 are not located at other opening and closing doors 20, then the push mechanism 40 can directly open the door.

[0061] 2. When only one type of salt is added, the initial state of the drive end 31 is at door No. 2. Then the first drive end rotates and drives all drive ends 31 to rotate to door No. 2. At this time, the push mechanism 40 can be activated to open the door.

[0062] 3. If the two seasonings, salt and sugar, are initially at door 1, then at least one of the driving ends 31 needs to move to door 2. At this time, the first driving end can be driven to rotate away from the second driving end, thus moving the second driving end to door 2. The other driving ends 31 remain at door 1. In this case, the first driving end only needs to rotate one revolution to open the doors for both seasonings at the same time. Alternatively, if the first driving end can play the role of opening the door, the first driving end can be directly driven to rotate to door 2 without affecting the other driving ends 31.

[0063] 4. Add two seasonings, salt and sugar. Initially, the drive end 31 is not at door 1 or door 2. At this time, the first drive end can rotate towards the direction of the second drive end, driving all drive ends 31 to rotate to door 1 or door 2. Then the first drive end rotates in the opposite direction, driving the nearest second drive end to rotate to door 2 or door 1.

[0064] 5. When three types of seasonings are required, if the initial state of the drive unit 31 is not at any of the preset open doors 20, there are two possible solutions:

[0065] One method is that the first driving end rotates to drive all driving ends 31 to one of the preset open opening and closing doors 20, then the first driving end rotates in the opposite direction, driving the third driving end to another preset open opening and closing door 20 through the second driving end, and then the first driving end rotates in the opposite direction again, driving the second driving end to the remaining preset open opening and closing door 20.

[0066] Another method is that the first drive end rotates to drive all drive ends 31 to one of the preset open opening and closing doors 20, then the first drive end rotates in the opposite direction to drive the second drive end to another preset open opening and closing door 20, and then the first drive end rotates in the opposite direction again to the remaining preset open opening and closing door 20.

[0067] To add more seasonings, follow the same logic as above.

[0068] After the aforementioned adjustment of the position of the drive end 31 is completed, the push mechanism 40 can be moved to achieve the effect of the drive end 31 driving the preset open door 20 to open and the preset closed door 20 to maintain the relationship.

[0069] This embodiment also provides a door opening and closing structure for a feeding device, which can execute the control method described above. For example... Figures 1 to 7 As shown, the opening and closing structure of the feeding device specifically includes a main support 10, multiple opening and closing doors 20, a selection drive mechanism 30, and a push mechanism 40. The main support 10 has a feeding channel 11 for feeding and multiple feeding ports 12 connected to the feeding channel 11. The opening and closing doors 20 are movably connected to the main support 10 and can open or close the feeding ports 12. The selection drive mechanism 30 has multiple drive ends 31 that are movably set. The drive ends 31 can switch between a position where they are driven to engage with the opening and closing doors 20 and a position where they are driven to separate from the opening and closing doors 20. All drive ends 31 can selectively engage with the preset open opening and closing doors 20. The selection drive mechanism 30 is connected to the push mechanism 40. The push mechanism 40 can drive the selection drive mechanism 30 to move and drive the opening and closing doors 20 that are driven to engage with the drive ends 31 to move, so as to open the corresponding opening and closing doors 20.

[0070] In this embodiment, the selection drive mechanism 30 is provided as described above. The selection drive mechanism 30 can drive the drive end 31 to change position according to the opening and closing requirements of the opening and closing door 20. This ensures that all preset open opening and closing doors 20 are engaged with the drive end 31, while preset closed opening and closing doors 20 are not engaged with the drive end 31. In this way, when the pushing mechanism 40 drives the selection drive mechanism 30 to move as a whole, each drive end 31 can open the preset open opening and closing door 20 and keep the preset closed opening and closing door 20 closed, thereby ensuring clean material feeding and avoiding material mixing.

[0071] It should be noted that the opening and closing structure of the feeding device in this embodiment is only one structural method for implementing the control method of the opening and closing structure of the feeding device. Other structures, such as the aforementioned gripper structure, can also be used to implement the control method.

[0072] In this embodiment, the direction of motion of the pushing mechanism 40 is consistent with the direction of motion of the opening and closing door 20. The opening and closing door 20 is axially movable along the extension direction of the feeding channel 11. Therefore, the direction of motion of the pushing mechanism 40 is also the axial direction of the feeding channel 11. Thus, when the pushing mechanism 40 drives the selection drive mechanism 30 to move along the direction of motion of the pushing mechanism 40, the selection drive mechanism 30 can drive the opening and closing door 20 to open and close. Of course, the pushing mechanism 40 can be moved or rotated, and its direction of motion can also be opposite to the direction of motion of the opening and closing door 20.

[0073] Optionally, the number of drive ends 31 is greater than or equal to the number of opening and closing doors 20 to ensure that all opening and closing doors 20 can be opened simultaneously. Preferably, the number of drive ends 31 is the same as the number of opening and closing doors 20. Of course, the number of drive ends 31 can also be less than the number of opening and closing doors 20, in which case at most only the number of opening and closing doors 20 driven by the drive ends 31 can be opened simultaneously.

[0074] like Figure 2 and Figure 3As shown, the main support 10 in this embodiment is cylindrical with a hollow middle section, which serves as the feeding channel 11. Multiple opening and closing doors 20 are arranged circumferentially on the sides of the main support 10, allowing them to be sequentially arranged around the feeding channel 11. By rotatably configuring at least a portion of the drive mechanism 30, the drive ends 31 can switch between aligned and staggered positions with each opening and closing door 20, thereby changing the engagement state between the drive ends 31 and the opening and closing doors 20. Since the drive ends 31 are driven sequentially by mutual abutment, they are not axially aligned during sequential rotation. Instead, adjacent drive ends 31 are staggered circumferentially within the feeding channel 11. Thus, only when one drive end 31 abuts against the side of an adjacent drive end 31 can it rotate together.

[0075] In this embodiment, when at least a portion of the selected drive mechanism 30 rotates, two adjacent drive ends 31 rotate in the circumferential direction of the feeding channel 11, and then the two abut and rotate synchronously, or at least one of the two adjacent drive ends 31 rotates in a direction away from the abutting direction to separate the two. More specifically, when at least a portion of the selected drive mechanism 30 rotates in the first direction, one drive end 31 approaches and abuts against another adjacent drive end 31, and then the two rotate together until they abut against the next drive end 31, and all three rotate together. This process is repeated, with multiple drive ends 31 abutting in sequence to achieve synchronous rotation, thereby adjusting the position. When the drive end 31 at the rear end of the drive mechanism 30 moves into position, at least a portion of the selected drive mechanism 30 rotates in the second direction opposite to the first direction. At this time, the drive end 31 at the front end of the drive mechanism 31 rotates in the opposite direction, thereby separating from the drive end 31, until the drive end 31 at the front end rotates to the other side of the drive end 31 at the rear end of the drive mechanism 31 and abuts against the drive end 31, causing it to rotate in the opposite direction. This process is repeated, with each drive end 31 separating in sequence. The specific process described above is the same as that in the aforementioned control method, and will not be repeated in detail here.

[0076] like Figure 1As shown, the selection drive mechanism 30 in this embodiment includes a drive element 32, a main selection ring 33, and a slave selection ring 34. The drive element 32 can be a motor, more specifically a stepper motor or other motor capable of precisely controlling the rotation angle. The main selection ring 33 is connected to the drive element 32 via a D-type connector or similar structure, and the drive element 32 directly drives the main selection ring 33 to rotate. Both the main selection ring 33 and the slave selection ring 34 have a drive end 31. Since the main selection ring 33 is directly driven and cooperates with the drive element 32, the drive end 31 of the main selection ring 33 is the active end, which is the first drive end mentioned in the aforementioned control method. The drive end 31 of the slave selection ring 34 is the driven end, which is the second to Nth drive end mentioned in the aforementioned control method. The driven end is located on the movement path of the active end. In this way, when the main selection ring 33 rotates, the side of the active end can squeeze and push the side of the driven end, thereby driving the driven end to rotate together. In this way, each driven end is sequentially switched between the position of docking with the opening and closing door 20 that needs to be opened and the position of separating from the opening and closing door 20.

[0077] like Figure 4 and Figure 5 As shown, in this embodiment, both the main selection ring 33 and the slave selection ring 34 are flat. The slave selection ring 34 is stacked on top of the main selection ring 33, and their axes coincide with the axis of the feeding channel 11. This facilitates driving, allowing the drive shaft of the drive member 32 to pass through the middle of the ring, while also reducing the size of the ring, which is beneficial for miniaturization. The active end and the driven end are located at the circumferential edges of the main selection ring 33 and the slave selection ring 34, respectively. Along the axial direction of the selection drive mechanism 30, which is also the axial direction of the feeding channel 11, the thickness of the active end is basically the same as the thickness of the main selection ring 33, while the thickness of the driven end is greater than the thickness of the slave selection ring 34. The protruding part of the driven end of the slave selection ring 34, which is stacked and attached to the main selection ring 33, extends towards the main selection ring 33, thus reaching the circumferential edge of the main selection ring 33. In this way, the active end is located on the path of the driven end, and when the active end rotates, it abuts against the driven end, driving the slave selection ring 34 to rotate.

[0078] The number of selector rings 34 can be set according to the number of opening and closing doors 20. When multiple selector rings 34 are provided, they are stacked together, and the structures of the selector rings 34 are exactly the same. In the stacked state, in two adjacent selector rings 34, the driven end of the selector ring 34 farther from the main selector ring 33 extends into the peripheral edge of the selector ring 34 closer to the main selector ring 33. For example, the part of the third drive end protruding from the selector ring 34 extends into the edge of the selector ring 34 where the second drive end is located, thereby abutting and cooperating with the second drive end. In this way, it is ensured that each drive end 31 can abut sequentially along the drive transmission direction to achieve transmission.

[0079] In this embodiment, the driving end 31 adopts a boss structure. Specifically, the active end is a first boss structure extending radially from the main selection ring 33, and the driven end is a second boss structure extending radially from the selection ring 34. The thickness of the second boss structure is greater than the thickness of the first boss structure. Of course, in addition to a boss structure, the driving end 31 can also adopt other structural forms, such as a groove.

[0080] It should be noted that the specific cooperation and setting method between the main selection ring 33 and the slave selection ring 34 is not limited to the above-mentioned content in this embodiment. Other setting methods can also be adopted as needed. For example, the main selection ring 33 adopts a gear structure, and the slave selection ring 34 is geared to the main selection ring 33. The two can be stacked or perpendicular. The slave selection rings 34 still adopt the above-mentioned cooperation method. In this case, the main selection ring 33 does not play the role of cooperating with the opening and closing door 20, but only plays the role of transmission, etc.

[0081] like Figures 1 to 3 As shown, in this embodiment, the main selection ring 33 is located at the end of the drive shaft of the drive member 32, while the secondary selection ring 34 is located on the side of the main selection ring 33 facing the drive member 32. At least a portion of the opening / closing door 20 is located between the secondary selection ring 34 and the drive member 32. This results in a shorter overall length of the engagement between the selection drive mechanism 30 and the opening / closing door 20, making the structure more compact and facilitating miniaturization. It should be noted that since the main selection ring 33 and the secondary selection ring 34 have a certain height when stacked, when the upper end of the opening / closing door 20 is at the same height as the drive member 32, it is preferable that when the active end of the main selection ring 33 contacts the opening / closing door 20 and drives it to open, the entire discharge port 12 corresponding to the opening / closing door 20 can be exposed. This is because the main selection ring 33 is closest to the discharge port 12, so as long as the main selection ring 33 can fully open the discharge port 12 where the opening / closing door 20 is located, the secondary selection ring 34 can also fully open the corresponding opening / closing door 20, thereby reducing the moving distance of the opening / closing door 20. Of course, the specific arrangement of the main selection ring 33, the slave selection ring 34 and the opening / closing door 20 can also be adjusted as needed, for example, the slave selection ring 34 can be set on the side of the main selection ring 33 away from the drive unit 32.

[0082] In this embodiment, the opening and closing structure of the unloading device also includes a detection component, which can be a photoelectric sensor, reed switch, angle encoder, or other components. The detection component is electrically connected to the selection drive mechanism 30 to detect the state of the selection drive mechanism 30. In actual detection, since the main selection ring 33 is the first end of the transmission, the detection component can only detect the main selection ring 33. Based on the rotation of the main selection ring 33, the control terminal analyzes and calculates the rotation position of each slave selection ring 34. Of course, the rotation angle positions of both the main selection ring 33 and the slave selection ring 34 can also be detected to ensure comprehensiveness and accuracy. The control terminal analyzes and calculates the rotation angles of the main selection ring 33 and the slave selection ring 34 based on the data detected by the detection component, and then determines the position of the drive end 31 and controls the rotation direction of the main selection ring 33 based on the rotation angle.

[0083] In this embodiment, the opening and closing door structure of the feeding device is arranged longitudinally, that is, the axis of the feeding channel 11 extends vertically, the opening and closing door 20 moves vertically, and the pushing mechanism 40 drives the selection drive mechanism 30 to move vertically as well. This conforms to the usage habits of the feeding device on the one hand, and the opening and closing door 20 is always downward under the force of gravity, avoiding the situation of being opened accidentally.

[0084] like Figure 6 As shown, the opening / closing door 20 in this embodiment is formed by bending a plate. Its longitudinal portion cooperates with the discharge port 12 and can block the discharge port 12. The upper portion is bent laterally and extends radially towards the discharge channel 11. This portion serves as the protruding end 21, which cooperates with the driving end 31. That is, the protruding end 21 is located above the driving end 31 and below the driving member 32. Thus, when the driving end 31 is aligned with the opening / closing door 20, the driving end 31 rotates to be directly below the protruding end 21. At this time, the protruding end 21... Located on the movement path of the drive end 31, when the pushing mechanism 40 drives the drive end 31 to move upward along the extension direction of the feeding channel 11, the drive end 31 abuts against the bottom surface of the protruding end 21, thereby driving the opening and closing door 20 to open upward through the protruding end 21; similarly, when the drive end 31 and the opening and closing door 20 are driven to separate and stagger, the drive end 31 avoids the direct underside of the protruding end 21, and at this time, when the drive end 31 moves upward, there is no cooperation between the drive end 31 and the protruding end 21, and the opening and closing door 20 remains closed. Of course, in addition to the above configuration, the structure of the opening and closing door 20 can also adopt other structures as needed, such as setting a hook or groove to cooperate with the drive end 31.

[0085] In this embodiment, along the circumference of the feeding channel 11, the circumferential length of the protruding ends 21 of each opening and closing door 20 can be relatively long, allowing the protruding ends 21 to be close to each other without gaps, or the circumferential length can be relatively short, allowing the protruding ends 21 to be spaced apart to form gaps. When there are no gaps, the driving end 31 must be aligned with one opening and closing door 20, and there is no situation where it is offset from all opening and closing doors 20. However, when there are gaps, the driving end 31 can be located at the gap, in which case the driving end 31 can be offset from all opening and closing doors 20.

[0086] In this embodiment, since the driving end 31 is only located below the protruding end 21, the driving end 31 can only drive the opening and closing door 20 to open. Therefore, the selective driving mechanism 30 in this embodiment also includes a closing structure 35, which closes the opening and closing door 20. The closing structure 35 can be the driving member 32 itself, a base for fixing provided on the driving member 32, or other structures. Specifically, when it is implemented by the driving member 32 itself, since the protruding end 21 is located below the driving member 32, the lower surface of the driving member 32 serves as the closing surface 351. Therefore, when the pushing mechanism 40 is reset downward, the closing surface 351 of the driving member 32 abuts against the protruding end 21, thereby pushing the opening and closing door 20 downward and closing the opened opening and closing door 20. When implemented using a base, the selection drive mechanism 30 in this embodiment also includes a base, which serves to fix and install the drive component 32. The base is connected to and moves synchronously with the push mechanism 40. The end of the base facing the opening and closing door 20 has a closing surface 351. The protruding end 21 of the opening and closing door 20 is located between the closing surface 351 and the drive end 31. Thus, when the push mechanism 40 moves towards the material feeding channel 11, i.e., downwards, the closing surface 351 abuts against the protruding end 21, and the closing surface 351 pushes the opening and closing door 20 downwards through the protruding end 21, thereby closing the opening and closing door 20. This embodiment uses the method of setting a base as the closing structure 35 to achieve door closing, such as... Figure 7 As shown. It should be noted that the above setting will close all opening and closing doors 20 when closing, regardless of whether the opening and closing doors 20 are fully open or partially open. After the action is completed, all opening and closing doors 20 will be closed.
