[0040] like Figures 1-8As shown, an embodiment of the present application proposes a set chopstick dispenser, comprising: a bin body 1, the bin body 1 having a storage cavity 11 with an upper opening, the storage cavity 11 constituting a storage space for stacking set chopsticks 8 (the set chopsticks 8 can be neatly stacked in the storage cavity 11 in the up and down directions under the constraint of the storage cavity 11); and a grabbing assembly 3, arranged at the top of the bin body 1, the grabbing assembly 3 having a grabbing portion that can move up and down on its moving trajectory, the grabbing portion having a grabbing position located above the storage space and a release position staggered with the storage space; the grabbing portion is used to grab the set chopsticks 8 at the grabbing position and release the set chopsticks 8 at the release position; the grabbing assembly 3 drives the grabbing portion to move between the grabbing position and the release position; the set chopstick dispenser also includes a shell (not shown in the figure) arranged outside the bin body 1, the shell being provided with a feeding port at the release position, so that when the grabbing assembly 3 grabs the set chopsticks 8 through the grabbing portion and moves it to the release position, the set chopsticks 8 are released and thrown out from the feeding port. During specific implementation, the gripping part is in the gripping position in the initial state. When the set of chopsticks 8 needs to be distributed, the gripping part moves downward and grabs the set of chopsticks 8 located below it, and then the gripping part moves up to the initial position, and the gripping component 3 drives the gripping part to move from the gripping position to the release position, so that when the gripping part moves to the release position, the gripping part is controlled to release the gripped set of chopsticks 8, so that the set of chopsticks 8 is thrown out from the feeding port of the shell, thereby completing the automatic distribution process of the set of chopsticks 8; after completing a complete distribution of the set of chopsticks 8, the gripping component 3 drives the gripping part from the release position to the gripping position again, and waits for the next distribution instruction of the set of chopsticks 8.

[0041] In some embodiments of the present application, Figure 3 As shown, the set chopsticks dispenser also includes a support frame 2 that moves up and down and is arranged in the storage cavity 11, so that the storage cavity 11 located above the support frame 2 constitutes a storage space, that is, the set chopsticks 8 are stacked on the support frame 2; a lifting component 4, which is connected to the support frame 2 and drives the support frame 2 to move up and down in the storage cavity 11; a controller, which is arranged at the top of the warehouse body 1, and the controller is electrically connected to the lifting component 4. There is a waiting position for grabbing in the storage space. When the set chopsticks 8 in the waiting position for grabbing is grabbed, the lifting component 4 receives a signal from the controller to make the lifting component 4 drive the support frame 2 to move up and move the set chopsticks 8 at the top to the waiting position for grabbing, so that when the grabbing part is at the grabbing position, the distance between the set chopsticks 8 at the top and the grabbing part is constant.

[0042] When the gripping portion returns to the gripping position from the release position again, the distance between the gripping portion and the set of chopsticks 8 at the top is kept constant.

[0043] In some embodiments of the present application, Figure 1 As shown, the grabbing assembly 3 includes a cylinder 31 (the cylinder 31 is connected to a control air source), and the grabbing part is connected to the retractable end of the cylinder 31. When it is necessary to grab the set of chopsticks 8, the cylinder 31 drives the grabbing part connected to the retractable end of the cylinder 31 to move downward to a predetermined distance under the action of the control air source, and grabs the set of chopsticks 8. After the grabbing is completed, the cylinder 31 drives the grabbing part to move up to the initial position, and then under the action of the swing assembly 5, drives the cylinder 31 to move from the grabbing position to the release position, and after moving to the release position, controls the grabbing part to release the grabbed set of chopsticks 8; after the release of the set of chopsticks 8 is completed, the swing assembly 5 drives the cylinder 31 to move from the release position to the grabbing position again to wait for the next grabbing of the set of chopsticks 8.

[0044] In some embodiments of the present application, Figure 1 As shown, the swing assembly 5 includes a driving motor 51 installed on the top of the warehouse body 1, and a rocker arm 52 is connected along the radial direction of the axis of the driving motor 51, and the other end of the rocker arm 52 is connected to the cylinder 31; the driving motor 51 is electrically connected to a first microcontroller, and the driving motor 51 receives a signal from the first microcontroller so that the driving motor 51 drives the cylinder 31 to move from the grasping position to the release position or from the release position to the grasping position; the driving motor 51 rotates and then drives the cylinder 31 to rotate through the rocker arm 52, and the first microcontroller controls the rotation angle and rotation direction of the driving motor 51, thereby driving the cylinder 31 to move between the grasping position and the release position, so as to realize the grasping of the set of chopsticks 8 at the grasping position by the grasping part and the release of the set of chopsticks 8 at the release position.

[0045] In some embodiments of the present application, Figure 4As shown, the grasping portion includes a vacuum suction cup 32 connected to a retractable end of the cylinder 31, and the vacuum suction cup 32 is connected to a vacuum pump (a solenoid valve is provided at the connection between the vacuum suction cup 32 and the vacuum pump, and the solenoid valve is controlled to be opened so that the vacuum suction cup 32 is connected to the outside world, and the solenoid valve is controlled to be closed so that the vacuum suction cup 32 is not connected to the outside world). The grasping position includes a grasping preparation position located above the set of chopsticks 8 (when the grasping work is not performed, the vacuum suction cup 32 is located at the grasping preparation position) and a grasping start position abutting against the set of chopsticks 8; when the retractable end of the cylinder 31 drives the vacuum suction cup 32 to move down to a predetermined distance (the vacuum suction cup 32 moves to the grasping start position, and at this time the vacuum suction cup 32 just abuts against the upper surface of the set of chopsticks 8, and the set of chopsticks 8 is packaged in the packaging bag), the first microcontroller controls the vacuum pump to start to extract the air in the vacuum suction cup 32 outwards, and maintain a certain pressure in the vacuum suction cup 32. After that, the first microcontroller controls the drive motor 51 to work and drives the cylinder 31 to move to the release position. After that, the first microcontroller controls the vacuum pump to stop working and controls the solenoid valve to open at the same time, so that the vacuum suction cup 32 is connected to the external air pressure. At this time, the set of chopsticks 8 adsorbed on the bottom of the vacuum suction cup 32 falls under the action of gravity (thrown out from the feeding port of the shell), thereby completing the automatic distribution of the set of chopsticks 8; then the first microcontroller controls the drive motor 51 to rotate in the opposite direction so as to move the cylinder 31 to the grabbing preparation position again (synchronously controlling the solenoid valve to close) to wait for the next grabbing of the set of chopsticks 8. In this solution, the driving motor 51 , the cylinder 31 , and the vacuum pump are all electrically connected to the first microcontroller and work together under the control of the first microcontroller to achieve the effect of automatically distributing the set of chopsticks 8 .

[0046] In some embodiments of the present application, Figure 6 As shown, one end of the support bracket 2 in the length direction is connected to a connecting portion 21 provided up and down, the upper end of the connecting portion 21 extends upwardly out of the storage cavity 11, and the end of the connecting portion 21 extending upwardly is connected to the lifting assembly 4, and the lifting assembly 4 drives the support bracket 2 to rise or fall in the storage cavity 11 through the connecting portion 21; Figure 7 As shown, a guide rail 13 can be fixed to a side wall of the storage cavity 11 near the lifting component 4 (the guide rail 13 has a guide groove extending up and down toward the side of the connecting portion 21), and a guide wheel 22 that cooperates with the guide groove is installed on the side of the connecting portion 21 facing the guide rail 13. When the lifting component 4 drives the connecting portion 21 to move up and down, the guide wheel 22 moves synchronously in the guide groove of the guide rail 13 to improve the stability of the supporting bracket 2 when it moves up and down.

[0047] In some embodiments of the present application, Figure 2 As shown, the lifting assembly 4 includes an electric push rod 41 arranged on one side of the warehouse body 1. The retractable end of the electric push rod 41 is connected to the connecting part 21. The electric push rod 41 is connected to a push rod motor 42. The push rod motor 42 drives the electric push rod 41 to move vertically, thereby driving the connecting part 21 to move vertically.

[0048] In some embodiments of the present application, Figure 1 、 Figure 5 As shown in FIG, the controller includes a photoelectric switch transmitter 61 and a photoelectric switch receiver 62 (the two constitute a beam-type photoelectric switch 6) which are diagonally arranged at the upper end of the chamber body 1. The working principle is as follows: the light emitted by the transmitter directly enters the receiver. When the detected object passes between the transmitter and the receiver and blocks the light, the beam-type photoelectric switch generates a switch signal; the photoelectric switch transmitter 61 and the photoelectric switch receiver 62 are connected to a second microcontroller. When the light between the photoelectric switch transmitter 61 and the photoelectric switch receiver 62 is not blocked (that is, the height of the uppermost set of chopsticks 8 is lower than that of the photoelectric switch transmitter 61 and the photoelectric switch receiver 62), the photoelectric switch generates a switch signal. The second microcontroller controls the electric push rod 41 to drive the support bracket 2 to move upward until the light between the photoelectric switch transmitter 61 and the photoelectric switch receiver 62 is blocked (the set of chopsticks 8 at the top blocks the light between the photoelectric switch transmitter 61 and the photoelectric switch receiver 62), and the second microcontroller controls the electric push rod 41 to stop moving, so that when the grasping part is in the grasping preparation position, the distance between the set of chopsticks 8 at the top and the grasping part is maintained at a constant value, so that the set of chopsticks 8 can be grasped each time the cylinder 31 drives the vacuum suction cup 32 to move down a constant distance.

[0049] In some embodiments of the present application, Figure 3 As shown, a limit switch 7 electrically connected to the second microcontroller is provided on the outer side wall of the upper end of the bin body 1 and the bottom of the bin body 1; an extension portion 23 extending outward from the storage cavity 11 is connected to the support bracket 2 (a slot is provided on the side wall of the bin body 1 for allowing the extension portion 23 to extend outward and allowing the extension portion 23 to move vertically with the support bracket 2). As the sets of chopsticks 8 are continuously distributed, the number of sets of chopsticks 8 on the support bracket 2 becomes smaller and smaller, and the height of the support bracket 2 in the storage cavity 11 becomes higher and higher, until When the extension portion 23 moves upward and abuts against the limit switch 7 located above, the second microcontroller controls the electric push rod 41 to move downward and drives the support frame 2 to move downward synchronously in the storage cavity 11, until it moves downward so that the extension portion 23 abuts against the limit switch 7 located below, the second microcontroller controls the electric push rod 41 to stop working (the support frame 2 is at the set lowest position in the storage cavity 11), and at this time, the set of chopsticks 8 can be replenished on the support frame 2 for the subsequent distribution of the set of chopsticks 8.

[0050] All power-consuming components in this solution are connected to an external power supply and powered by the external power supply.

[0051] In some embodiments of the present application, Figure 1 As shown, an opening 12 is provided on one side wall of the bin body 1, which runs through the bin body 1 from top to bottom. The setting of the opening 12 facilitates observation of the number and placement of the set of chopsticks 8 in the storage cavity 11, and also helps to reduce the consumption of materials when preparing the bin body 1.

[0052] The working process of the present invention is as follows: in the initial state, the grabbing part is in the grabbing position; when it is necessary to distribute the set of chopsticks 8, the cylinder 31 drives the grabbing part to move down a set distance and grab the set of chopsticks 8, and then the cylinder 31 drives the grabbing part to move up to the initial position height, and then the grabbing component 3 drives the grabbing part to move from the grabbing position to the release position. After moving to the release position, the grabbing part is controlled to release the grabbed set of chopsticks 8. At this time, the controller synchronously controls the lifting component 4 to drive the supporting frame 2 to move up a certain distance in the storage cavity 11, so that when the grabbing component 3 drives the grabbing part to move to the grabbing position again, the distance between the grabbing part and the set of chopsticks 8 at the top is maintained at a constant value.

[0053] In summary, the embodiment of the present invention provides a set chopsticks dispensing machine, which provides a warehouse body 1 for stacking set chopsticks 8 and a grabbing assembly 3 on the warehouse body 1, and the grabbing assembly 3 has a grabbing part that can move up and down and is used to grab the set chopsticks 8; the grabbing part has a grabbing position for grabbing the set chopsticks 8 and a releasing position for releasing the set chopsticks 8, and the grabbing assembly 3 drives the grabbing part to move between the grabbing position and the releasing position; the position height of the supporting frame 2 in the storage cavity 11 is dynamically adjusted by the controller so that the distance between the set chopsticks 8 at the top and the grabbing part is constant, so that each time the grabbing part moves down a set distance, it can grab the set chopsticks 8 in the warehouse body 1, and then the grabbing assembly 3 drives the grabbing part to move from the grabbing position to the releasing position, thereby realizing the distribution of the grabbed set chopsticks 8, thereby realizing the effect of automatically distributing the set chopsticks 8.

[0054] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present invention. These improvements and replacements should also be regarded as the scope of protection of the present invention.
