Description

Technical Field

[0001] The invention relates to the field of automated food distribution and storage and retrieval equipment, and in particular to a meal transport module and a meal cabinet. Background Art

[0002] Nowadays, the Internet is increasingly integrated into daily life, and the rapid development of online supermarkets and logistics has significantly improved people's lives. With the improvement of the quality of life, people's demand for convenience and comfort in life is increasing. Especially in hospitals, office buildings, schools and other places, it is necessary to first develop meal cabinets for centralized meal preparation and unified distribution, which can store meals in a warm manner and quickly serve meals, so as to meet the needs of standardized group meals with efficient centralized supply.

[0003] Currently, the food cabinets on the market are equipped with multiple storage spaces for storing tableware, and meal transport modules that can be moved to corresponding storage spaces, and each storage space is provided with a meal delivery module for pushing the tableware out of the storage space and onto the meal transport module.

[0004] The existing meal delivery module is provided with a detection line. When the tableware touches the detection line, the meal delivery module drives the tableware to continue to move to the middle of the meal transport module through the friction between itself and the bottom contact surface of the tableware. At this time, no part of the tableware is still in contact with the meal delivery module. After completion, the tableware is delivered to the outside through the meal delivery module to prevent the tableware from being overturned.

[0005] However, the position of the detection line is fixed, and the distance that the meal serving module pushes the tableware is also fixed. Once the size of the tableware becomes larger, the area of ​​the bottom contact surface of the tableware in contact with the meal transport module accounts for a small proportion of the total area of ​​the bottom contact surface of the tableware. At this time, the friction force generated by the contact surface between the meal transport module and the bottom of the tableware is not enough to drive the larger tableware to move to the middle of the meal transport module. If the meal is served at this time, the tableware will be overturned and the meal serving will fail, resulting in the inability of meal cabinets on the market to serve tableware of various sizes.

[0006] Therefore, the compatibility of existing dining cabinets is not high, and manufacturers need to customize different dining cabinets according to tableware of different sizes. Summary of the invention

[0058] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention is further described in detail below in conjunction with the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. Thus, a feature indicated in this specification will be used to illustrate one of the features of an embodiment of the present invention, rather than implying that each embodiment of the present invention must have the described features. In addition, it should be noted that this specification describes many features. Although certain features can be combined together to illustrate possible system designs, these features can also be used in other combinations that are not explicitly described. Thus, unless otherwise stated, the described combinations are not intended to be limiting.

[0059] The principle and structure of the present invention are described in detail below with reference to the accompanying drawings and embodiments.

[0060] Example 1

[0061] See attached Figure 1 The present invention proposes a meal transport module, comprising: a base 10, a transmission structure 20, a first stepless adjustment detection device 30 and a second stepless adjustment detection device 40;

[0062] Among them, the transmission structure 20 is installed on the base 10, and its conveying surface conveys tableware along the X-axis direction; the first stepless adjustment detection device 30 and / or the second stepless adjustment detection device 40 are movably installed on the base 10 and are arranged at intervals along the Y-axis direction; and the first stepless adjustment detection device 30 and the second stepless adjustment detection device 40 form at least one detection line 50 on the conveying surface of the transmission structure 20 that can move along the conveying direction of the tableware.

[0063] It should be noted that the first stepless adjustment detection device 30 is disposed on one side of the base 10 along the X-axis direction, and the second stepless adjustment detection device 40 is disposed on the other side of the base 10 along the X-axis direction.

[0064] It should be noted that the meal transport module proposed in this embodiment is used to transport tableware, snacks, drinks or other objects that are easy to transport. For ease of understanding, the meal transport module of this embodiment is illustrated by transporting tableware; and the tableware of this embodiment is illustrated by a rectangular lunch box.

[0065] The meal transport module proposed in this embodiment further includes a control unit, which is electrically connected to the transmission structure 20, the first stepless adjustment detection device 30 and the second stepless adjustment detection device 40 respectively.

[0066] In this way, when the size of the tableware delivered to the meal transport module this time is larger than the size last time (referred to as large-size tableware, the same throughout the text), if the position of the detection line 50 does not move along the middle of the meal transport module, the large-size tableware will not have enough area to contact the transmission structure 20, resulting in the transmission structure 20 being unable to drive the large-size tableware to move to the preset safety area in the middle of the meal transport module and transport it to the meal outlet. At this time, the meal will be knocked over and the meal will fail. Therefore, in order to enable the meal transport module to transport tableware of various sizes, the present invention sets at least one detection line 50 that can move along the conveying direction of the tableware through the first stepless adjustment detection device 30 and the second stepless adjustment detection device 40. In this way, when the size of the tableware delivered to the meal transport module is larger than the previous size, the detection line 50 will be away from the meal inlet of the meal transport module (the meal inlet of the meal transport module is the opening through which the tableware enters the meal transport module). In this way, when the large-sized tableware blocks the detection line 50, the contact area of ​​the large-sized tableware with the transmission structure 20 meets the transmission requirements. Then the control unit starts the transmission structure 20, so that the transmission structure 20 drives the large-sized tableware to move to the preset safety area in the middle of the meal transport module. Finally, the control unit controls the entire meal transport module to move to the meal outlet to complete the meal outlet.

[0067] Similarly, when the size of the tableware delivered to the meal transport module this time is smaller than the size last time (referred to as small-sized tableware, the same throughout the text), the detection line 50 will be close to the meal entrance of the meal transport module to prevent the contact area between the tableware and the transmission structure 20 from being too large. When the small-sized tableware blocks the detection line 50, the control unit starts the transmission structure 20, so that the transmission structure 20 drives the small-sized tableware to move to the preset safety area in the middle of the meal transport module. Finally, the control unit controls the entire meal transport module to move to the meal outlet to complete the meal delivery.

[0068] Therefore, the present invention sets at least one detection line 50 that can move along the conveying direction of the tableware through the first stepless adjustment detection device 30 and the second stepless adjustment detection device 40, so as to adapt to tableware of different sizes by adjusting the detection line 50, so that the transmission structure 20 can smoothly move the tableware of different sizes to the meal transport module, thereby successfully serving the meal.

[0069] In order to improve the detection accuracy of the detection line 50 and reduce the risk of false triggering, refer to the attached Figure 1 A first stepless adjustment detection device 30 is provided on one side of the base 10 along the X-axis direction and close to one end of the Y-axis direction, and a second stepless adjustment detection device 40 is provided on the other side of the base 10 along the X-axis direction and close to the other end of the Y-axis direction, and the detection line 50 is arranged at an angle.

[0070] It should be noted that, at this time, the first stepless adjustment detection device 30 and the second stepless adjustment detection device 40 are arranged diagonally.

[0071] In order to enable the first stepless adjustment detection device 30 to better detect whether the tableware has reached the specified position, refer to the attached Figure 2 and 4 , this embodiment proposes a structure of a first stepless adjustment detection device 30:

[0072] The first stepless adjustment detection device 30 proposed in this embodiment includes a first displacement actuator 301, a first rotation actuator 302 and a first optical sensor 303;

[0073] The moving end of the first displacement actuator 301 is connected to the first rotation actuator 302, and the rotating end of the first rotation actuator 302 is connected to the first optical sensor 303;

[0074] The first displacement actuator 301 is used to drive the first optical sensor 303 to move along the Y-axis direction, and the first rotation actuator 302 is used to drive the first optical sensor 303 to rotate.

[0075] It should be noted that the first optical sensor 303 proposed in this embodiment is preferably an infrared sensor, and the first rotation actuator 302 is preferably a stepping motor. The control unit is electrically connected to the first displacement actuator 301, the first rotation actuator 302 and the first optical sensor 303 respectively.

[0076] In this way, the first optical sensor 303 emits infrared rays to the second stepless adjustment detection device 40 to form a detection line 50. If tableware blocks the detection line 50, it indicates that the tableware has reached the designated position in the meal transport module. At this time, the second stepless adjustment detection device 40 cannot receive the infrared rays emitted by the first optical sensor 303. Then the second stepless adjustment detection device 40 sends a first warning signal to the control unit to enable the control unit to start the transmission structure 20, so that the transmission structure 20 drives the tableware to move to the preset safety area in the middle of the meal transport module and transport it to the meal outlet.

[0077] When the size of the tableware delivered to the meal transport module is larger than the previous size, the control unit will first drive the first optical sensor 303 to slide away from the side of the meal intake port of the meal transport module through the first displacement actuator 301, so that the detection line 50 is away from the meal intake port of the meal transport module, thereby increasing the contact area between the large-sized tableware and the transmission structure 20, so as to increase the friction between the large-sized tableware and the transmission structure 20; at the same time, the control unit drives the first optical sensor 303 to rotate through the first rotation actuator 302, so that the first optical sensor 303 is always in the same straight line with the detection line 50 formed between the second stepless adjustment detection device 40 during the movement; then after the large-sized tableware blocks the detection line 50, the control unit will start the transmission structure 20, and smoothly drive the large-sized tableware to move to the preset safety area in the middle of the meal transport module. Finally, the control unit controls the entire meal transport module to move to the meal outlet to complete the meal outlet.

[0078] In order to enable the meal transport module to transport tableware of various sizes, this embodiment provides a detection line 50 that can move along the conveying direction of the tableware. Figure 4 , specifically:

[0079] A first positioning block 101 is provided on one side of the base 10 along the X-axis direction. A first displacement actuator 301 and a first rotation actuator 302 are also provided in the first positioning block 101. A first guide rail 102 is provided on the first positioning block 101. A first optical sensor 303 is matched and mounted on the first guide rail 102.

[0080] The first displacement actuator 301 can drive the first optical sensor 303 to slide along the first guide rail 102 .

[0081] In this way, when the size of the tableware delivered to the meal transport module is larger than the previous size, the control unit will first drive the first optical sensor 303 to slide along the first guide rail 102 away from the dining port of the meal transport module through the first displacement actuator 301, so that the detection line 50 is away from the dining port of the meal transport module; at the same time, the control unit drives the first optical sensor 303 to rotate through the first rotation actuator 302, so that the first optical sensor 303 is always in the same straight line with the detection line 50 formed between the second stepless adjustment detection device 40 during the movement; when the large-sized tableware blocks the detection line 50, the control unit will start the transmission structure 20, and smoothly drive the large-sized tableware to move to the preset safety area in the middle of the meal transport module. Finally, the control unit controls the entire meal transport module to move to the meal outlet to complete the meal outlet.

[0082] In order to enable the second stepless adjustment detection device 40 to better detect whether the tableware has reached the specified position, refer to the attached Figure 3 , this embodiment proposes a structure of a second stepless adjustment detection device 40:

[0083] The second stepless adjustment detection device 40 proposed in this embodiment includes a second rotary actuator 401 and a second optical sensor 402;

[0084] A second rotary actuator 401 is disposed on the other side of the base 10 along the X-axis direction, and a rotating end of the second rotary actuator 401 is connected to the second optical sensor 402;

[0085] The second rotary actuator 401 is used to drive the second optical sensor 402 to rotate.

[0086] It should be noted that the second optical sensor 402 proposed in this embodiment is preferably a photoelectric sensor; the second rotary actuator 401 is preferably a stepping motor. The control unit is electrically connected to the second rotary actuator 401 and the second optical sensor 402 respectively.

[0087] In this way, the first optical sensor 303 emits infrared rays to the second optical sensor 402 to form a detection line 50, and at the same time, the second optical sensor 402 also emits visible light or invisible light to the first optical sensor 303 to form another detection line 50, so as to further improve the detection accuracy and reduce the risk of false triggering.

[0088] In this way, when tableware blocks the detection line 50, it indicates that the tableware has reached the designated position in the meal transport module. At this time, the second optical sensor 402 cannot receive the infrared light emitted by the first optical sensor 303 and / or the second optical sensor 402 receives the light emitted by itself. Then the second optical sensor 402 will send a first warning signal and / or a second warning signal to the control unit, so that the control unit starts the transmission structure 20, so that the transmission structure 20 drives the tableware to move to the preset safety area in the middle of the meal transport module and transport it to the meal outlet.

[0089] When the size of the tableware delivered to the meal transport module is larger than the previous size, the control unit will first drive the first optical sensor 303 to slide away from the side of the meal inlet of the meal transport module through the first displacement actuator 301, so that the detection line 50 is away from the meal inlet of the meal transport module, thereby increasing the contact area between the large-sized tableware and the transmission structure 20, so as to increase the friction between the large-sized tableware and the transmission structure 20; at the same time, the control unit drives the first optical sensor 303 to rotate through the first rotation actuator 302, and the second rotation actuator 401 drives the second optical sensor 402 to rotate, so that the detection line 50 formed between the first optical sensor 303 and the second optical sensor 402 during the movement is always on the same straight line; then after the large-sized tableware blocks the detection line 50, the control unit will start the transmission structure 20, and smoothly drive the large-sized tableware to move to the preset safety area in the middle of the meal transport module. Finally, the control unit controls the entire meal transport module to move to the meal outlet to complete the meal outlet.

[0090] In order to enable the transmission structure 20 to smoothly drive the tableware to move to the preset safe area in the middle of the meal transport module, refer to the attached Figure 1 , this embodiment proposes a transmission structure 20:

[0091] The transmission structure 20 proposed in this embodiment includes a roller 201 and a first driving device 202;

[0092] A plurality of rollers 201 are disposed at the bottom of the base 10 along the Y-axis direction, and each of the rollers 201 is connected to the rotating end of the first driving device 202;

[0093] The first driving device 202 is used to drive all the rollers 201 to rotate, so as to move the tableware pushed into the meal transport module to a preset safety area of ​​the meal transport module.

[0094] It should be noted that the control unit is also electrically connected to the first driving device 202 , and the first driving device 202 is preferably a motor.

[0095] In this way, when tableware blocks the detection line 50, part of the bottom of the tableware will be located above the roller 201, and then the control unit will start the first driving device 202, and the first driving device 202 will drive all the rollers 201 to rotate counterclockwise, and the rollers 201 will drive the tableware to move to the preset safety area in the middle of the meal transport module.

[0096] Among them, refer to the attached Figure 1 A push plate 105 is further provided on one side of the base 10 along the X-axis direction. The push plate 105 is connected to a pushing end of a pushing device 106. The pushing device 106 is used to push the push plate 105 along the Y-axis direction of the base 10.

[0097] It should be noted that the control unit is also electrically connected to the pushing device 106. And the first stepless adjustment detection device 30 will not hinder the pushing of the push plate 105 on the same side.

[0098] In this way, when the control unit controls the entire meal transport module to move to the meal outlet, the control unit will start the pushing device 106, so that the pushing device 106 controls the push plate 105 to push along the Y-axis direction of the base 10 to push the tableware out of the meal transport module to the meal outlet to complete the meal delivery.

[0099] Therefore, the operation process of the meal transport module proposed in this embodiment is as follows:

[0100] First, the first optical sensor 303 emits infrared rays to the second optical sensor 402 to form a detection line 50, and at the same time, the second optical sensor 402 also emits visible light or invisible light to the first optical sensor 303 to form another detection line 50. Then, if tableware is delivered to the meal transport module, causing the tableware to block the detection line 50, the control unit will receive the first warning signal and / or the second warning signal sent by the second optical sensor 402, and then the control unit starts the first driving device 202, and the first driving device 202 will drive all rollers 201 to rotate counterclockwise to move the tableware to the preset safety area in the middle of the meal transport module; then the control unit will move the entire meal transport module to the meal outlet, and then start the pushing device 106, so that the pushing device 106 controls the push plate 105 to push along the Y-axis direction of the base 10 to push the tableware out of the meal transport module to the meal outlet to complete the meal delivery.

[0101] Among them, if during the process of conveying the tableware to the meal transport module, it is found that the size of the tableware conveyed this time is larger than that of the tableware conveyed last time, the control unit will first drive the first optical sensor 303 to slide away from the dining port of the meal transport module through the first displacement actuator 301, so that the detection line 50 is away from the dining port of the meal transport module; at the same time, the control unit drives the first optical sensor 303 to rotate through the first rotation actuator 302, and drives the second optical sensor 402 to rotate through the second rotation actuator 401, so that the detection line 50 formed between the first optical sensor 303 and the second optical sensor 402 is always on the same straight line during the movement.

[0102] In this way, when the large-sized tableware blocks the detection line 50, the contact area between the large-sized tableware and the roller 201 will increase, and then the control unit will start the first driving device 202 to smoothly drive the large-sized tableware to move to the preset safety area in the middle of the meal transport module. Finally, the control unit controls the entire meal transport module to move to the meal outlet, and then the control unit starts the pushing device 106, so that the pushing device 106 controls the pushing plate 105 to push along the Y-axis direction of the base 10 to push the tableware out of the meal transport module to the meal outlet to complete the meal delivery.

[0103] Example 2

[0104] Based on Example 1, Figure 5 and 7 This embodiment proposes another structure of the second stepless adjustment detection device 40:

[0105] The second stepless adjustment detection device 40 proposed in this embodiment includes a second displacement actuator 403, a third rotation actuator 404 and a third optical sensor 405;

[0106] The moving end of the second displacement actuator 403 is connected to the third rotation actuator 404, and the rotating end of the third rotation actuator 404 is connected to the third optical sensor 405;

[0107] The second displacement actuator 403 is used to drive the third optical sensor 405 to move along the Y-axis direction, and the third rotation actuator 404 is used to drive the third optical sensor 405 to rotate.

[0108] It should be noted that the third optical sensor 405 proposed in this embodiment is preferably a photoelectric sensor; the third rotation actuator 404 is preferably a stepping motor. The control unit is electrically connected to the second displacement actuator 403, the third rotation actuator 404 and the third optical sensor 405 respectively.

[0109] In this way, the first optical sensor 303 emits infrared rays to the third optical sensor 405 to form a detection line 50, and at the same time, the third optical sensor 405 also emits visible light or invisible light to the first optical sensor 303 to form another detection line 50, so as to further improve the detection accuracy and reduce the risk of false triggering.

[0110] In this way, when tableware blocks the detection line 50, it indicates that the tableware has reached the designated position in the meal transport module. At this time, the third optical sensor 405 cannot receive the infrared light emitted by the first optical sensor 303 and / or the third optical sensor 405 receives the light emitted by itself, and then the third optical sensor 405 will send a first warning signal and / or a second warning signal to the control unit, and then the control unit will start the first driving device 202 after receiving it, and the first driving device 202 will drive all rollers 201 to rotate counterclockwise to move the tableware to the preset safety area in the middle of the meal transport module; then the control unit will move the entire meal transport module to the meal outlet, and then start the pushing device 106, so that the pushing device 106 controls the push plate 105 to push along the Y-axis direction of the base 10 to push the tableware out of the meal transport module to the meal outlet to complete the meal delivery.

[0111] Among them, if during the process of conveying the tableware to the meal transport module, it is found that the size of the tableware conveyed this time is larger than that of the tableware conveyed last time, the control unit will first drive the first optical sensor 303 to slide away from the dining port of the meal transport module through the first displacement actuator 301, and at the same time, the control unit also drives the third optical sensor 405 to slide away from the dining port of the meal transport module through the second displacement actuator 403, so that the detection line 50 is away from the dining port of the meal transport module; at the same time, the control unit drives the first optical sensor 303 to rotate through the first rotation actuator 302, and drives the third optical sensor 405 to rotate through the third rotation actuator 404, so that the detection line 50 formed between the first optical sensor 303 and the third optical sensor 405 during the movement is always on the same straight line.

[0112] In this way, when the large-sized tableware blocks the detection line 50, the contact area between the large-sized tableware and the roller 201 will increase, and then the control unit will start the first driving device 202 to smoothly drive the large-sized tableware to move to the preset safety area in the middle of the meal transport module. Finally, the control unit controls the entire meal transport module to move to the meal outlet.

[0113] In order to enable the meal transport module to transport tableware of various sizes, this embodiment provides another detection line 50 that can move along the conveying direction of the tableware. Figure 6 , specifically:

[0114] A second positioning block 103 is provided on the other side of the base 10 along the X-axis direction, and a second displacement actuator 403 and a third rotation actuator 404 are provided in the second positioning block 103; a second guide rail 104 is provided on the second positioning block 103, and a third optical sensor 405 is matched and installed on the second guide rail 104;

[0115] The second displacement actuator 403 can drive the third optical sensor 405 to slide along the second guide rail 104 .

[0116] In this way, when the size of the tableware delivered to the meal transport module is larger than the previous size, the control unit will first drive the first optical sensor 303 to slide away from the side of the meal inlet of the meal transport module through the first displacement actuator 301, and at the same time, the control unit also drives the third optical sensor 405 to slide away from the side of the meal inlet of the meal transport module through the second displacement actuator 403, so that the detection line 50 is away from the meal inlet of the meal transport module, so that the two detection lines 50 formed between the first optical sensor 303 and the third optical sensor 405 are away from the meal inlet of the meal transport module; at the same time, the control unit drives the first optical sensor 303 to rotate through the first rotation actuator 302, so that the first optical sensor 303 is always on the same straight line with the two detection lines 50 formed between the second stepless adjustment detection device 40 during the movement; when the large-sized tableware blocks the detection line 50, the control unit will then start the first driving device 202, so as to smoothly drive the large-sized tableware to move to the preset safety area in the middle of the meal transport module, and finally the control unit controls the entire meal transport module to move to the meal outlet.

[0117] Example 3

[0118] Based on the same inventive concept, refer to the attached Figure 8-9 The present invention also proposes a meal cabinet, which includes the meal transport module described above.

[0119] Wherein, the dining cabinet also includes:

[0120] A plurality of storage spaces 60 for storing tableware, each of the storage spaces 60 correspondingly provided with a meal serving module 70;

[0121] An X-axis track 80 is arranged along the X-axis direction of the dining cabinet, and a dining transport module is slidably connected to the X-axis track 80;

[0122] A lifting module 90 is arranged along the Z-axis direction of the dining cabinet, and the moving end of the lifting module 90 is connected to the X-axis track 80;

[0123] The lifting module 90 drives the meal transport module to move to the corresponding storage space 60 via the X-axis track 80 , and the meal delivery module 70 pushes the tableware in the storage space 60 to the meal transport module.

[0124] It should be noted that a second driving device 81 is also provided on the X-axis track 80, and the second driving device 81 is used to drive the meal transport module to slide along the X-axis track 80. The storage space 60 is provided with multiple columns along the Z-axis direction, and each column is provided with multiple horizontally arranged storage spaces 60. In addition, a detection module (not shown, the same throughout) is also provided in the meal cabinet, and the detection module is used to detect the size of the tableware sent into the storage space, and upload the detection data to the control unit, so that the control unit moves the detection line 50 along the conveying direction of the tableware, so as to facilitate the smooth delivery of tableware of different sizes into the meal transport module, and ensure the success of meal delivery.

[0125] And the control unit is electrically connected to the lifting module 90 , the second driving device 81 and the detection module respectively.

[0126] In this way, when the food cabinet can be used normally and no food is served, the X-axis track 80 is located in front of the storage space 60 and at the bottom of the storage space 60, and the lifting module 90 is located on one side of the storage space 60 along the X-axis direction.

[0127] When any storage space 60 needs to serve food, the control unit will first drive the X-axis track 80 to rise to the corresponding row of the storage space 60 where the food needs to be served through the lifting module 90, and then the control unit will drive the meal transport module to move to the storage space 60 where the food needs to be served through the second driving device 81. At this time, the food outlet of the storage space 60 and the food inlet of the meal transport module are at the same horizontal plane; then the meal serving module 70 pushes the tableware in the storage space 60 to the meal transport module until the tableware blocks the detection line 50, and then the control unit closes the meal serving module 70 and resets it, and then the control unit The control unit restarts the first driving device 202, so that the first driving device 202 drives all the rollers 201 to rotate counterclockwise, and the rollers 201 drive the tableware to move to the preset safety area in the middle of the meal transport module. Then the control unit turns off the first driving device 202, and starts the second driving device 81 and the lifting module 90 in sequence to move the meal transport module to the meal outlet of the food cabinet. Then the control unit starts the pushing device 106 again, so that the pushing device 106 controls the pushing plate 105 to push along the Y-axis direction of the base 10 to push the tableware out of the meal transport module to the meal outlet, thereby completing the meal delivery.

[0128] When the tableware is transported to the meal transport module and it is found that the size of the tableware transported this time is larger than that of the tableware transported last time, the control unit will first drive the first optical sensor 303 to slide away from the dining port of the meal transport module through the first displacement actuator 301, so that the detection line 50 is away from the dining port of the meal transport module; at the same time, the control unit drives the first optical sensor 303 to rotate through the first rotation actuator 302, and drives the third optical sensor 405 to rotate through the third rotation actuator 404, so that the detection line 50 formed between the first optical sensor 303 and the third optical sensor 405 is always on the same straight line during the movement.

[0129] In this way, when the large-sized tableware blocks the detection line 50, the contact area between the large-sized tableware and the roller 201 will increase, and then the control unit will start the first driving device 202 to smoothly drive the large-sized tableware to move to the preset safety area in the middle of the meal transport module. Finally, the control unit controls the entire meal transport module to move to the meal outlet, so that the meal is successfully served, thereby solving the problem that the meal cabinet cannot serve a variety of tableware of different sizes, and improving the compatibility of the meal cabinet.
