TECHNICAL FIELD

[0001] The present application relates to the field of mechanical equipment, in particular to a single-piece mask intelligent dispensing machine. BACKGROUND

[0002] As an effective tool for epidemic prevention, masks are playing an increasingly important role in public places, especially in places with large crowds. In order to encourage people to consciously wear masks in public places, various mask dispensing machines have appeared in the prior art. Such devices can be placed in public places to automatically distribute masks to people in need. The mask dispensing machines in the prior art generally use automatic or semi-automatic working mode, and are internally configured with friction wheels and other mask pushing mechanisms to automatically push a mask to people in need. The defects of the mask dispensing machines in the prior art are that the friction between the smooth surface of the friction wheel and the mask is difficult to control stably, which can easily cause the mask to be difficult to push out or the mask to wrinkle inside the machine. Secondly, the intelligence of the device is poor, and generally requires the user to trigger the button to take the mask. SUMMARY

[0003] The technical problem to be solved by the present application is the poor stability of the mask pushing mechanism in the mask dispensing machine in the prior art and the low intelligence of the entire mask dispensing machine.

[0004] To solve the above technical problems, the technical scheme adopted by the present application is as follows: a single-piece mask intelligent dispensing machine, comprising a box body, a first friction wheel, a driving assembly and a feeding assembly;

[0005] The feeding assembly comprises a feeding spring and a supporting plate, the feeding spring is vertically installed inside the box body, and the supporting plate is installed on the top of the feeding spring, and the supporting plate is used for storing stacked masks;

[0006] The first friction wheel is located directly above the supporting plate, the feeding spring exerts a spring force on the supporting plate so that the supporting plate supports the stacked masks below the first friction wheel, the first friction wheel is provided with rubber felt pieces along the circumference, the rubber felt pieces are pressed on the stacked masks on the surface of the supporting plate, and the driving assembly drives the first friction wheel to rotate, and the rotating first friction wheel can push the mask adhered thereto horizontally;

[0008] Further, a mask passage is provided between the mask outlet and the supporting plate, a second friction wheel is installed in the mask passage, and the surface of the second friction wheel is also provided with rubber felt pieces; the first friction wheel first pushes the mask into the mask passage, and the second friction wheel continues to push the mask towards the mask outlet.

[0009] Further, the mask intelligent dispenser further comprises a camera and a controller, the camera is installed on the box body, the controller is provided with a face recognition system, when the controller recognizes that there is a person without wearing a mask in front of the camera, the controller controls the first friction wheel and the second friction wheel to rotate to distribute the mask; when the mask intelligent dispenser is placed in a public area, the user only needs to approach the dispenser to be recognized, and then the dispenser automatically outputs a mask, the whole process does not need the user to operate and contact the dispenser, and the risk of cross infection is effectively reduced.

[0010] The mask intelligent dispenser of the present application can also be provided with a mobile chassis, and the box body is installed on the mobile chassis to realize the movement of the dispenser. Specifically, the controller detects the number N of faces appearing in the camera per unit time, and when N exceeds the set value, the controller controls the mobile chassis to stop at the current position; when N does not exceed the set value, the controller controls the mobile chassis to move and approach the face without wearing a mask in the camera. The mask dispenser of the present application has the function of automatically detecting the passenger flow, and when the passenger flow is large, the dispenser stays in place and adopts a fixed-point mask dispensing method to avoid affecting the passage; when the passenger flow is small, the dispenser moves to approach the person without wearing a mask and adopts an active mask dispensing method.

[0011] Further, the mask outlet is provided with a photoelectric sensor for detecting the mask, and the controller detects whether the mask at the mask outlet is taken away by a person through the photoelectric sensor. As long as there is a mask at the mask outlet that has not been taken away, the first friction wheel and the second friction wheel will not start.

[0012] Further, the mask dispenser further comprises a voice player, when the first friction wheel releases the mask, the voice player plays the set voice, which can attract the attention of pedestrians and remind pedestrians that there is a machine distributing masks at present.

[0013] Specifically, the driving assembly comprises a motor, a driving shaft, a driven shaft, a transmission gear and a transmission belt, the first friction wheel is installed on the driven shaft, the driving shaft and the driven shaft are driven through the transmission gear and the transmission belt, the motor drives the driving shaft to rotate, and the driving shaft drives the driven shaft and the first friction wheel to rotate.

[0014] In the application, the mask stack stored in the dispensing machine is on the pallet, when the topmost mask is pushed away laterally, there is also friction between the topmost mask and the second topmost mask, which has the probability of causing uncontrollable lateral displacement of the second topmost mask; in order to overcome this defect, the mask dispensing machine also includes a locking assembly, the locking assembly includes a cam, a reciprocating air pump, an air cylinder, a first piston rod and a first return spring, the cam is installed on the driving shaft, the reciprocating air pump is provided with a second piston rod and a second return spring is sleeved on the second piston rod, and the second piston rod is in contact with the cam; the first piston rod is located in the air cylinder, the reciprocating air pump is in communication with the rodless cavity in the air cylinder, the first return spring is located in the rod cavity and is sleeved on the first piston rod, and the rodless cavity of the air cylinder is provided with an exhaust hole; the size of the exhaust hole should meet: the exhaust speed of the exhaust hole is less than the speed of the reciprocating air pump filling the air cylinder; the first piston rod is vertically above the pallet, and the bottom end of the first piston rod points to the tail of the stacked mask on the pallet.

[0015] When the driving shaft rotates, the driving shaft drives the driven shaft and the first friction wheel to rotate, so that the topmost mask on the pallet starts to move horizontally; at the same time, the rotating cam and the second return spring realize the reciprocating motion of the second piston rod together, so that the reciprocating air pump starts to work and fills the rodless cavity of the air cylinder with air, because the filling speed is greater than the exhaust speed of the exhaust hole, so the first piston rod of the air cylinder will descend and press the tail of the stacked mask on the pallet, because the topmost mask has moved a small distance horizontally at this time, so the first piston rod will press the second topmost mask, so that the second topmost mask is fixed and will not be dragged by the topmost mask;

[0016] When the topmost mask is pushed out, the driving shaft stops rotating, the reciprocating air pump stops working, and then the compressed air in the rodless cavity of the air cylinder is gradually exhausted from the exhaust hole, and the first piston rod gradually rises and resets under the action of the first return spring.

[0017] Further, the rod cavity of the air cylinder is provided with a limiting ring, and the limiting ring is used to limit the limit position of the downward movement of the first piston rod.

DETAILED DESCRIPTION

[0026] The application will be further described in detail below in combination with specific embodiments.

[0027] Embodiment 1

[0028] As shown in Figure 1 and Figure 2 , the single-piece mask intelligent dispensing machine of the embodiment comprises a box body 100, a first friction wheel 200, a driving assembly 300, a feeding assembly 400, a mobile chassis 500, a camera 600 and a controller.

[0029] The box body 100 is installed on the mobile chassis 500, which should have navigation and obstacle avoidance functions. The mobile chassis 500 of the embodiment adopts a Shihua MR600 mobile chassis.

[0030] The feeding assembly 400 comprises a feeding spring 410 and a supporting plate 420. The feeding spring 410 is vertically installed inside the box body 100, and the supporting plate 420 is installed on the top of the feeding spring 410. The supporting plate 420 is used to store stacked masks 700.

[0031] The first friction wheel 200 is located directly above the supporting plate 420. The feeding spring 410 exerts a spring force on the supporting plate 420 so that the supporting plate 420 props the stacked masks 700 under the first friction wheel 200. The first friction wheel 200 is provided with rubber pads 210 along the circumference, which press on the stacked masks 700 on the surface of the supporting plate 420. The driving assembly 300 drives the first friction wheel 200 to rotate, and the rotating first friction wheel 200 can push the masks 700 adhering thereto horizontally.

[0032] The surface of the box body 100 is provided with a mask outlet 110, and a mask passage 120 is provided between the mask outlet 110 and the supporting plate 420. A second friction wheel 800 is installed in the mask passage 120, and the surface of the second friction wheel 800 is also provided with rubber pads 210. The first friction wheel 200 first pushes the masks 700 into the mask passage 120, and the second friction wheel 800 continues to push the masks 700 to the mask outlet 110.

[0033] The driving assembly 300 comprises a motor, a driving shaft 310, a driven shaft 320, a transmission gear 330 and a transmission belt 340. The first friction wheel 200 is installed on the driven shaft 320. The driving shaft 310 and the driven shaft 320 are driven through the transmission gear 330 and the transmission belt 340. The motor drives the driving shaft 310 to rotate, which drives the driven shaft 320 and the first friction wheel 200 to rotate.

[0034] The mask 700 dispensing principle of the embodiment is as shown in Figure 3As shown, masks 700 are stacked on tray 420. Under the action of feeding spring 410, tray 420 pushes masks 700 under the first friction wheel 200. If masks 700 need to be dispensed, the first friction wheel 200 rotates and pushes the top mask 700 to the left into mask channel 120. The rotating second friction wheel 800 pushes mask 700 to mask outlet 110.

[0035] The camera 600 is installed on the housing 100. The controller is equipped with the Baidu Smart Cloud offline SDK face mask detection and recognition system. When the controller detects that someone is not wearing a mask 700 in front of the camera 600, the controller controls the first friction wheel 200 and the second friction wheel 800 to rotate and distribute the mask 700. When the smart mask dispenser of this invention is placed in a public area, the user only needs to approach the dispenser to be recognized. Then the dispenser automatically outputs a mask 700. The whole process does not require user operation or contact with the dispenser, effectively reducing the risk of cross-infection.

[0036] In this embodiment, the controller employs different mask dispensing modes based on pedestrian traffic. The controller detects the number N of faces appearing within the camera 600 per unit time. When N exceeds a set value, the controller controls the moving chassis 500 to remain at its current position. When N does not exceed the set value, the controller controls the moving chassis 500 to move closer to the faces of people not wearing masks (700) in the camera 600. The mask dispensing machine of this invention has an automatic pedestrian traffic detection function. When pedestrian traffic is high, the dispensing machine remains stationary, dispensing masks at fixed points to avoid obstructing passage. When pedestrian traffic is low, the dispensing machine autonomously moves closer to people not wearing masks (700), dispensing masks proactively.

[0037] A photoelectric sensor for detecting mask 700 is installed at the mask outlet 110. The controller uses the photoelectric sensor to detect whether the mask 700 at the mask outlet 110 has been taken away. As long as there is an untaken mask 700 at the mask outlet 110, the first friction wheel 200 and the second friction wheel 800 will never be activated.

[0038] The intelligent mask dispenser in this embodiment is also equipped with a voice player. When the first friction wheel 200 releases the mask 700, the voice player plays a preset voice message. The voice message can attract the attention of pedestrians and remind them that a machine is distributing masks 700.

[0039] Example 2

[0040] like Figures 4 to 6 As shown, this embodiment is basically the same as embodiment 1, except that a locking component 900 is added inside the housing 100 in this embodiment. It should be noted that, for ease of illustration, this embodiment... Figures 4 to 6The transmission gear 330 and the transmission belt 340 are hidden in the middle.

[0041] The locking assembly 900 comprises a cam 910, a reciprocating air pump 920, an air cylinder 930, a first piston rod 940 and a first return spring 950, the cam 910 is installed on the driving shaft 310, the reciprocating air pump 920 is provided with a second piston rod 921 and a second return spring 922 is sleeved on the second piston rod 921, the second piston rod 921 is in contact with the cam 910; the first piston rod 940 is located in the air cylinder 930, the reciprocating air pump 920 is in communication with a rodless cavity in the air cylinder 930, the first return spring 950 is located in a rod cavity and is sleeved on the first piston rod 940, and the rodless cavity of the air cylinder 930 is provided with an exhaust hole 931; the size of the exhaust hole 931 should meet the condition that the exhaust speed of the exhaust hole 931 is less than the speed of the reciprocating air pump 920 filling air into the air cylinder 930; the first piston rod 940 is vertically above the supporting plate 420, and the bottom end of the first piston rod 940 points to the tail of the mask 700 stacked on the supporting plate 420; a limiting ring 932 is arranged in the rod cavity of the air cylinder 930, and the limiting ring 932 is used to limit the limit position of the downward movement of the first piston rod 940.

[0042] As shown in Figure 5 and Figure 6 , when the driving shaft 310 rotates, the driving shaft 310 drives the driven shaft 320 and the first friction wheel 200 to rotate, so that the topmost mask 700 on the supporting plate 420 starts to move horizontally; at the same time, the rotating cam 910 and the second return spring 922 jointly realize the reciprocating movement of the second piston rod 921, so that the reciprocating air pump 920 starts to work and fills air into the rodless cavity of the air cylinder 930, and since the filling speed is greater than the exhaust speed of the exhaust hole 931, the first piston rod 940 of the air cylinder 930 will descend and press the tail of the mask 700 stacked on the supporting plate 420, and since the topmost mask 700 has moved a small distance horizontally to the position shown in Figure 6 , the first piston rod 940 will press the second top mask 700, so that the second top mask 700 is fixed and will not be dragged by the topmost mask 700; when the topmost mask 700 is pushed out, the driving shaft 310 stops rotating, the reciprocating air pump 920 stops working, and then the compressed air in the rodless cavity of the air cylinder 930 is gradually exhausted from the exhaust hole 931, and the first piston rod 940 gradually ascends under the action of the first return spring 950 to the position shown in Figure 5 .

[0043] The locking assembly 900 in the embodiment takes the driving shaft 310 as a power source, and is started and stopped synchronously with the first friction wheel 200, which overcomes the defect that when the topmost mask 700 is pushed horizontally, there is a probability that the second top mask 700 also produces uncontrollable horizontal displacement.

[0044] While the embodiments of the present application have been described in the specification, these embodiments are only for the purpose of illustration and should not be construed to limit the scope of the present application. Various omissions, substitutions and changes in forms and details of the present application can be made by those skilled in the art without departing from the spirit of the present application.
