The embodiment of the application provides a loading and unloading device which can be used for a cloud rail conveying system of an intelligent restaurant and can enable transported materials to be in a determined orientation. As shown in fig. 1 and fig. 2, the feeding and discharging device includes: a tray assembly 2, the tray assembly 2 being for placing a material; a bracket 1, wherein the bracket 1 is used for accommodating a tray assembly 2; a rotation driving unit 3, wherein the rotation driving unit 3 is mounted on the bracket 1 and is used for driving the tray unit 2 to rotate; and a detection assembly for judging whether the tray assembly 2 is rotated to a preset position and controlling the rotation driving assembly 3 to operate or stop operating according to the judging result. Wherein, the preset position is a position which is convenient for a customer to take dishes or for a chef to take dinner plates.
In this embodiment, during the dish feeding and discharging process by the rail transportation system, the initial orientation of the tray assembly 2 in the dish feeding and discharging device is uncertain (may not rotate to a preset position), and there is a possibility that the tray assembly 2 is not oriented to the customer, which causes inconvenient meal taking for the customer. At this time, whether the tray assembly 2 is in the required direction (whether the tray assembly 2 rotates to the preset position) is judged by the detection assembly, when the judgment result of the detection assembly is that the tray assembly 2 does not rotate to the preset position, the rotary driving assembly 3 is started to drive the tray assembly 2 to rotate, and when the detection assembly obtains that the tray assembly 2 rotates to the preset position, the rotary driving assembly 3 is controlled to stop working, so that the tray assembly 2 is positioned at the preset position which is convenient for a customer to take dishes. Therefore, through setting up detection component and the rotary drive subassembly 3 that mutually support, can control tray subassembly 2 and rotate the position that the convenience of customers got the dish to improve the user experience of going up and down the dish device.
Specifically, as shown in fig. 3, the bracket 1 is provided with a limiting frame 4, the detection assembly comprises a sensor 42 and a trigger 221, one of the sensor 42 and the trigger 221 is arranged on the tray assembly 2, and the other is arranged on the limiting frame 4; when the tray assembly 2 is not rotated to the preset position, the rotary driving assembly 3 is in an operating state, and when the tray assembly 2 is rotated to the preset position, the sensor 42 senses with the trigger 221 to control the rotary driving assembly 3 to stop operating.
In this embodiment, when feeding or discharging is required (material is taken out from the tray assembly 2 or is placed on the tray assembly 2), the tray assembly 2 is pushed into the bracket 1, and the tray assembly 2 can be abutted against the limiting frame 4 in the process of moving along the first direction X, so that the tray assembly 2 is limited to move continuously along the first direction X by the limiting frame 4, and at this time, the tray assembly 2 may not rotate to a preset position. When the tray assembly 2 does not rotate to the preset position, the sensor 42 and the trigger 221 cannot sense, the detection assembly obtains that the tray assembly 2 is not at the preset position, so that the tray assembly 2 is controlled to rotate under the driving of the rotation driving assembly 3, when the detection assembly detects that the tray assembly 2 rotates to the preset position, the sensor 42 and the trigger 221 sense, the detection assembly obtains the judgment result that the tray assembly 2 is at the preset position, so that the rotation driving assembly 3 is controlled to stop rotating, and the tray assembly 2 stops at the preset position, so that a customer is convenient to take dishes.
More specifically, as shown in fig. 3, 6 and 7, at least part of the limiting frame 4 has an arc structure, at least two proximity switches are circumferentially arranged, the proximity switches are sensors 42, at least two metal blocks are circumferentially arranged on the tray assembly 2, and the metal blocks are triggers 221; the proximity switch and the metal block are in one-to-one correspondence, so that the rotary driving assembly 3 can be controlled to stop working.
In this embodiment, as shown in fig. 3, the limiting frame 4 has a part of an arc structure, and the bottom of the tray assembly 2 is generally circular, so that the limiting frame 4 can limit the movement of the tray assembly 2 along the first direction X and the second direction Y, thereby preventing the tray assembly 2 from shaking, and meanwhile, the limiting frame 4 with the arc structure cannot limit the rotation of the tray assembly 2, thereby enabling the tray assembly 2 to rotate under the driving of the rotation driving assembly 3. Meanwhile, when the sensor 42 and the trigger 221 are implemented by a proximity switch and a metal block, respectively, the structure of the sensor 42 and the trigger 221 can be simplified and the cost can be reduced. In addition, the quantity of the proximity switches is the same as that of the metal blocks, when one part of the proximity switches corresponds to the metal blocks and the other part of the proximity switches does not correspond to the metal blocks, the detection assembly judges that the tray assembly 2 does not rotate to the preset position, and only when the proximity switches correspond to the metal blocks one by one, the detection assembly can judge that the tray assembly 2 rotates to the preset position, so that the accuracy of a judgment result is improved.
As shown in fig. 4 and 6, the bottom of the tray assembly 2 is provided with a circumferential judgment limiting ring 22, a plurality of grooves can be machined along the circumferential direction of the circumferential judgment limiting ring 22, and a metal block is installed in the grooves to serve as a trigger 221. Correspondingly, the number of proximity switches installed on the limit frame 4 is the same as the number of the triggers 221 and corresponds to one, as in the embodiment shown in fig. 4 and 6, two metal blocks are arranged at intervals on the circumference determination limit ring 22 of the tray assembly 2, and correspondingly, two proximity switches are arranged at intervals on the limit frame 4.
Specifically, as shown in fig. 2 and 7, the limiting frame 4 is connected to a first driving member 41, and the first driving member 41 is configured to drive the limiting frame 4 to move along the first direction X, so that the limiting frame 4 abuts against or releases from abutting against the tray assembly 2. The first driving member 41 is mounted on the bracket 1.
In this embodiment, when feeding or discharging is required (material is taken out from the tray assembly 2 or is placed in the tray assembly 2), the tray assembly 2 is pushed into the bracket 1, and at this time, the first driving member 41 drives the limiting frame 4 to approach the tray assembly 2 along the first direction X, and makes the limiting frame 4 abut against the tray assembly 2, so as to limit the movement of the tray assembly 2 along the first direction X. When loading or unloading is accomplished, first drive piece 41 drive spacing 4 is kept away from tray assembly 2 along first direction X, and spacing 4 and tray assembly 2 release the butt for tray assembly 2 can leave support 1. Therefore, by providing the first driving member 41, the position of the tray assembly 2 in the first direction X can be conveniently restricted, thereby further improving the positional accuracy of the tray assembly 2 within the holder 1.
The first driving member 41 may be a stepping screw motor, a cylinder, or the like.
The stopper 4 is provided with a guide wheel 43 for abutting against the tray assembly 2. As shown in fig. 7, the guide wheels 43 are located at both ends of the arc-shaped portion of the stopper 4 and are rotatable about the Z-direction. When the limit frame 4 moves along the first direction X and abuts against the tray assembly 2, the tray assembly 2 abuts against the guide wheel 43 of the limit frame 4, so that a buffer effect is achieved through the guide wheel 43, and impact between the tray assembly 2 and the limit frame 4 is reduced. When spacing 4 and tray subassembly 2 butt and tray subassembly 2 rotate, the corresponding rotation of guide pulley 43 also under the effect of tray subassembly 2, and the friction between tray subassembly 2 and the spacing 4 has been reduced in the rotation of guide pulley 43, makes the rotation of tray subassembly 2 comparatively steady to reduce the energy consumption of rotatory drive assembly 3.
The guide wheel 43 is covered with an elastic pad, so as to further reduce the impact between the limit frame 4 and the tray assembly 2.
In a specific embodiment, as shown in fig. 7 and 8, the loading and unloading device further includes a limiting component 5, where the limiting component 5 is disposed on the limiting frame 4, and when the tray component 2 rotates to a preset position, the limiting component 5 is used to cooperate with the tray component 2 to limit the rotation of the tray component 2. The limiting frame 4 limits the movement of the tray assembly 2 along the first direction X and the second direction Y, and when the tray assembly 2 rotates to a preset position, the limiting assembly 5 further limits the rotation of the tray assembly 2, and at this time, the movement and rotation of the tray assembly 2 along the first direction X and the second direction Y are limited, that is, the tray assembly 2 is at the preset position capable of feeding and discharging, and the tray assembly 2 is prevented from shaking at the position, so that the user can safely take out materials from the tray assembly 2 conveniently.
Specifically, as shown in fig. 3, 6 and 7, the tray assembly 2 is provided with a notch 222, and the limiting assembly 5 includes a limiting block 51 and a first elastic member 52, and the first elastic member 52 is located between the limiting block 51 and the limiting frame 4; when the tray assembly 2 rotates to the preset position, the limiting block 51 can extend into the notch 222 along the first direction X relative to the limiting frame 4 under the driving of the first elastic member 52, so as to limit the rotation of the tray assembly 2.
In the present embodiment, one end of the first elastic member 52 contacts the stopper 4, and the other end contacts the stopper 4. When the tray assembly 2 is not rotated to the preset position, the tray assembly 2 restricts the stopper 51 from being extended, and at this time, the first elastic member 52 is compressed by the stopper 51 and the stopper 4. When the tray assembly 2 rotates to a preset position, the notch 222 arranged on the tray assembly 2 corresponds to the limiting block 51, the tray assembly 2 does not limit the movement of the limiting block 51 along the first direction X any more, and therefore the limiting block 51 is driven to extend into the notch 222 along the first direction X under the resilience force of the first elastic piece 52, and rotation of the tray assembly 2 is limited through the limiting block 51. Therefore, by arranging the first elastic member 52, when the tray assembly 2 rotates to the preset position, the limiting block 51 can automatically extend into the notch 222 of the tray assembly 2 under the resilience force of the first elastic member 52, so that the reliability and sensitivity of limiting the rotation of the tray assembly 2 by the limiting assembly 5 are improved.
The notch 222 is disposed on the circumferential judgment limiting ring 22 at the bottom of the tray assembly 2, and the shape and size of the notch 222 correspond to those of the limiting block 51, so long as the limiting block 51 can extend into the notch 222. The first elastic member 52 may be a spring or an elastic pad.
In addition, as shown in fig. 6, the notch 222 is located between the two triggers 221 of the detection assembly.
Further, as shown in fig. 7 to 9, the limiting component 5 further includes an eccentric wheel 53 and a second driving member 54 which are connected, and the limiting block 51 is connected with a rotating wheel 511; during the rotation of the eccentric wheel 53, it can cooperate with the rotating wheel 511 to drive the limiting block 51 to retract along the first direction X by the rotating wheel and compress the first elastic member 52.
In the present embodiment, as shown in fig. 8 and 9, the eccentric wheel 53 rotates around the rotation center, and the distance between each of the outer circumferences of the eccentric wheel 53 and the rotation center is not exactly the same, that is, the eccentric wheel 53 has a large diameter section and a small diameter section. When the large diameter section of the eccentric wheel 53 contacts with the rotating wheel 511 in the rotating process, the distance between the rotating center of the eccentric wheel 53 and the rotating center of the rotating wheel 511 is large, so that the rotating wheel 511 is pushed by the eccentric wheel 53 to move along the first direction X away from the tray assembly 2, and the limiting block 51 connected with the rotating wheel 511 is driven to move along the first direction X away from the tray assembly 2 in the moving process, so that the limiting block 51 is in a retracted state and compresses the first elastic piece 52, and at the moment, the tray assembly 2 is not rotated to a preset position. When the small diameter section of the eccentric wheel 53 contacts the rotating wheel 511 in the rotating process, the distance between the rotating center of the eccentric wheel 53 and the rotating center of the rotating wheel 511 is small, so that the rotating wheel 511 is pushed by the eccentric wheel 53 to move along the first direction X and approach the tray assembly 2, the limiting block 51 can stretch out under the resilience force of the first elastic piece 52, and at the moment, the tray assembly 2 rotates to a preset position.
Therefore, the limiting assembly 5 can conveniently control the limiting block 51 to extend or retract along the first direction X by providing the eccentric wheel 53 and the rotating wheel 511 which are matched with each other, so that the limiting assembly 5 can be conveniently in an extending state or a retracting state.
In addition, when the tray assembly 2 and the limiting frame 4 are not in contact, the limiting block 51 should be in a retracted state to prevent the limiting block 51 from affecting the contact between the tray assembly 2 and the limiting frame 4. When the material needs to be taken out of or placed on the tray assembly 2, the stopper 51 is required to restrict the movement of the tray assembly 2 so that the tray assembly 2 is in a relatively stable state.
The eccentric wheel 53 may be a circular wheel having a rotation center deviated from the center of the circle, or may be a cam, as long as the distance between the outer circumference of the eccentric wheel 53 and the rotation center thereof is not exactly the same. The second driving member 54 may be a dc motor or a stepping motor, etc., and drives the eccentric wheel 53 to rotate to repeatedly achieve the extended and retracted states of the stopper 51.
In the above embodiments, as shown in fig. 7 to 9, the rotation driving assembly 3 includes the third driving member 31, the transmission assembly 32 and the rotation member 33 that are connected, the rotation member 33 can be connected to the tray assembly 2, and the rotation member 33 can drive the tray assembly 2 to rotate under the driving of the third driving member 31.
In the present embodiment, the transmission component 32 transmits the power generated by the third driving component 31 to the rotating component 33, and the rotating component 33 drives the tray component 2 to rotate, so that the tray component 2 is driven to reach the preset position, and therefore, by providing the rotating component 33, the stability and reliability of the rotation of the tray component 2 driven by the third driving component 31 can be improved.
Wherein the third driving member 31 is typically a combination of a stepper motor and a right angle decelerator. The drive assembly 32 is typically a combination of a synchronizing wheel and a timing belt, and the rotational speed of the pallet assembly 2 can also be changed by changing the synchronizing wheel to a different size.
Specifically, as shown in fig. 10 and 11, the rotating member 33 is provided with a damper 34, and the damper 34 is used to contact the tray assembly 2 to rotate the tray assembly 2.
In this embodiment, the damping member 34 can be driven to rotate during the rotation of the rotating member 33, and the damping member 34 contacts the tray assembly 2, so that the tray assembly 2 can be driven to rotate by the damping force between the damping member 34 and the tray assembly 2, and the stability and reliability of the rotation of the rotating member 33 driving the tray assembly 2 are improved.
The tray assembly 2 includes a tray and a guide head 23 connected to the tray, the rotating member 33 is sleeved on the guide head 23, meanwhile, the damping member 34 is connected to the bottom of the rotating member 33, and when the tray assembly 2 is not in a lifting state, the damping member 34 can be abutted to the top of the tray, so that the damping member 34 and the top of the tray have damping force. The damping member 34 may be a rubber pad or the like.
Further, as shown in fig. 10 and 11, a second elastic member 35 is provided between the damper member 34 and the rotating member 33 in a compressed state so that the damper member 34 is pressed against the tray assembly 2.
In this embodiment, the second elastic member 35 in a compressed state has a force to separate the damping member 34 and the rotating member 33 from each other, so that the damping member 34 is pressed against the tray by the second elastic member 35, the friction between the damping member 34 and the tray is increased, and the slip between the damping member 34 and the rotating member 33 in the rotation process of the tray assembly 2 is further reduced, so that the rotation process of the tray assembly 2 is smoother.
Wherein the second elastic member 35 may be a spring.
Specifically, as shown in fig. 10 and 11, the rotary driving assembly 3 further includes a connection piece 36 located between the damping member 34 and the rotating member 33, the connection piece 36 is provided with a guide rod 37, and the second elastic member 35 is located between the rotating member 33 and the connection piece 36 and is sleeved on the guide rod 37. In this embodiment, the guide rod 37 can limit the extending and contracting direction of the second elastic member 35, so that the elastic force of the second elastic member 35 acts on the damping member 34 vertically, increasing the friction between the damping member 34 and the guide head 23, and the connecting piece 36 is used for mounting the damping member 34 and the guide rod 37 on the rotating member 33.
The connecting piece 36 may be made of a material having high rigidity, such as metal.
In a specific embodiment, as shown in fig. 4 and 5, the tray assembly 2 further includes a protective door 21, and the protective door 21 can be opened in a circumferential direction so that the tray assembly 2 has an opening. The arrangement of the protective door 21 improves the tightness of the tray assembly 2, prevents materials and foreign matters in the tray assembly 2 from falling from the tray assembly 2, and improves the safety of the tray assembly 2. Meanwhile, the tray assembly 2 is provided with only one determined opening, under the cooperation of the rotary driving assembly 3, the detection assembly and the limiting assembly 5, the tray assembly 2 can rotate to a preset position, and at the moment, the opening direction of the tray assembly 2 can facilitate a customer to take dishes, so that the user experience is improved.
