[0003] Chinese Patent CN211857618U discloses a transmission device for a self-service vending machine. The transmission device for the self-service vending machine includes a control unit, a clamping unit, a dropping door, a feeding unit, a heating unit and a bin door. The control unit is electrically connected to the clamping unit, the dropping door, the feeding unit and the heating unit to control the actions of each part, and drives the lunch box to pass through the clamping unit, the dropping door, the feeding unit and the heating unit in sequence, and finally sends it out of the vending machine through the bin door to complete the transmission process of the lunch box inside the vending machine. Among them, a bin door is installed outside the heating unit. The bin door is provided with a spring-back component. The DC motor drives the pushing component to send the lunch box together with the heating unit out of the bin door. After the user takes away the lunch box, the DC motor drives the pushing component to return to the initial position, the heating unit retracts, and the bin door closes.

[0004] However, there are at least the following problems in the related art: In the process of the feeding unit in the prior art sending the lunch box together with the heating unit out of the bin door, when the lunch box and the heating unit reach the connection between the bin door and the feeding unit, the pushing component of the feeding unit cannot continue to move towards the bin door, so that the lunch box and the heating unit stagnate at the connection between the bin door and the feeding unit, resulting in the situation that the feeding unit cannot push the lunch box and the heating unit to the position outside the bin door, thereby reducing the use effect of the transmission device. Summary of the Utility Model

[0005] The technical problem solved by the utility model is that in the process of the feeding unit in the prior art sending the lunch box together with the heating unit out of the bin door, when the lunch box and the heating unit reach the connection between the bin door and the feeding unit, the pushing component of the feeding unit cannot continue to move towards the bin door, so that the lunch box and the heating unit stagnate at the connection between the bin door and the feeding unit, resulting in the situation that the feeding unit cannot push the lunch box and the heating unit to the position outside the bin door, thereby reducing the use effect of the transmission device.

[0006] To solve the above problems, on the one hand, the present utility model provides a pushing device for a vending machine. The vending machine is used to accommodate lunch boxes. The pushing device includes: a bracket, on one side of the bracket there is a placement position for placing lunch boxes; a pushing member, the pushing member is movably connected to the bracket; a driving component, the driving component is drivingly connected to the pushing member to enable the pushing member to reciprocate on the bracket; wherein, when the pushing member is in a first relative position opposite to the placement position, at least a part of the pushing member extends out of the bracket to push the lunch box placed at the placement position to a target position.

[0007] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: By providing a pushing member, and when the pushing member is in the first relative position, at least a part of the pushing member extends out of the bracket. During the process of the pushing member performing a pushing action on the lunch box and pushing the lunch box to the target position of the vending machine, the lunch box can be stably pushed to the target position, thus avoiding the situation where the lunch box stagnates at the connection between the target position and the pushing device, resulting in the pushing member being unable to push the lunch box to the target position, and improving the use effect of the pushing device.

[0008] Specifically, in the prior art, when the lunch box and the heating unit reach the connection between the bin door and the sending unit, the pushing component of the sending unit cannot continue to move in the direction of the bin door, causing the lunch box and the heating unit to stagnate at the connection between the bin door and the sending unit, resulting in the situation where the sending unit cannot push the lunch box and the heating unit to the outside of the bin door, thereby reducing the use effect of the transmission device. In the present solution, the provided pushing member, when the pushing member is in the first relative position, at least a part of the pushing member extends out of the bracket. Thus, when the lunch box reaches the connection between the target position and the pushing device, the pushing member can still continue to move in the direction of the target position, enabling the pushing member to continue to push the lunch box in the direction of the target position. When the connecting member is at one end of the bracket close to the target position, at least a part of the pushing member extends out of the bracket and is located at the position of the target position together with the lunch box. Thus, the pushing member stably pushes the lunch box to the target position, thereby improving the use effect of the pushing device.

Detailed implementation manners

[0036] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the following detailed description of the specific embodiments of the present utility model will be given with reference to the accompanying drawings.

[0037] Such as Figure 1As shown, on the one hand, an embodiment of the present utility model provides a pushing device 100 for a vending machine. The vending machine is used to accommodate lunch boxes, and the vending machine is provided with a target position for the output of lunch boxes. The pushing device 100 is installed close to the target position. The pushing device 100 includes a bracket 200, and a pushing member 300 is arranged on the bracket 200. The pushing member 300 is movably connected to the bracket 200. In this solution, the pushing member 300 is slidably connected to the bracket 200, and the pushing member 300 is used to push the lunch box placed at the placement position to the target position. And a driving component 400 is drivingly connected to the pushing member 300 to enable the pushing member 300 to reciprocate on the bracket 200 to push the lunch box to the target position. Wherein, when the pushing member 300 is located at a first relative position opposite to the placement position, at least a part of the pushing member 300 extends out of the bracket 200 to push the lunch box placed at the placement position to the target position.

[0038] For example, the pushing member 300 is provided with a connecting portion connected to the bracket 200 and a pushing portion in contact with the lunch box. When the lunch box reaches the connection position between the target position and the pushing device 100, the connecting portion can continue to move in the direction of the target position, so that the pushing portion can continue to push the lunch box in the direction of the target position. When the connecting portion is located at one end of the bracket 200 close to the target position, the pushing portion and the lunch box are both located at the position of the target position, so that the pushing member 300 stably pushes the lunch box to the target position, thereby improving the use effect of the pushing device 100.

[0039] Specifically, as Figure 1 shown, when the pushing member 300 is located at the first relative position, the position where the pushing member 300 is located is the position after the pushing device 100 completes the pushing action on the lunch box. Among them, in order to prevent the lunch box from slipping out of the conveyor belt 500 during the pushing process of the pushing device 100 on the lunch box, the contact surface between the pushing portion and the lunch box can be set to an arc shape.

[0040] Furthermore, as Figures 4 to 7 shown, the bracket 200 is provided with a chute 210, and the connecting portion of the pushing member 300 is provided with a sliding wheel 310 that cooperates with the chute 210 to enable the pushing member 300 to be slidably connected to the bracket 200.

[0041] Furthermore, as Figure 1 shown, the pushing device 100 further includes a conveying component. The conveying component is arranged on the bracket 200 and is connected to the connecting portion, and drives the sliding wheel 310 to reciprocate in the chute 210 through the conveying component.

[0042] Further, the conveying assembly includes a conveyor belt 500 and a rotating member 600. The conveyor belt 500 is disposed between the bracket 200 and the pushing member 300, and the conveyor belt 500 is connected to the connecting portion. The rotating member 600 is disposed on the bracket 200 and is rotationally engaged with the conveyor belt 500. Wherein, the driving member 400 drives the rotating member 600 to rotate, so that when the pushing member 300 is located at a second relative position which is misaligned with the placing position, the conveyor belt 500 drives the pushing member 300 to move from the second relative position to the first relative position.

[0043] When a vending machine is provided with a conveying mechanism (not shown in the figure) to convey the lunch box to the pushing device 100, if the pushing member 300 is located at the first relative position, it will block the conveying mechanism (not shown in the figure) from conveying the lunch box to the placing position of the pushing device 100. In this solution, after the pushing member 300 completes the pushing, the pushing member 300 is located at a second relative position which is misaligned with the placing position, so as to prevent the pushing member 300 from hindering the conveying mechanism (not shown in the figure) from conveying the lunch box to the placing position of the pushing device 100, thereby increasing the stability of the lunch box during the conveying process.

[0044] Further, when the pushing member 300 is located at the second relative position, the driving member 400 rotates in the first direction to drive the pushing member 300 to move to the first relative position.

[0045] Further, when the pushing member 300 is located at the first relative position, the driving member 400 rotates in a second direction opposite to the first direction to drive the pushing member 300 to move to the second relative position.

[0046] Specifically, the rotating member 600 includes a driving runner 610 and a driven runner 620 which are oppositely arranged, and the conveyor belt 500 is sleeved outside both the driving runner 610 and the driven runner 620. Wherein, the driving runner 610 is disposed at one end of the bracket 200, the driven runner 620 is disposed at the other end of the bracket 200, and the conveyor belt 500 is rotationally engaged with the driving runner 610 and the driven runner 620. Wherein, when the driving member 400 drives the driving runner 610 to rotate, the conveyor belt 500 is driven to transmit.

[0047] Further, the pushing device 100 further includes a first connecting block 330 and a second connecting block 340. The first connecting block 330 is disposed between the conveyor belt 500 and the connecting portion to fixedly connect the conveyor belt 500 and the connecting portion. The second connecting block 340 is disposed at the end of the connecting portion to fixedly connect the sliding wheel 310 and the connecting portion. Wherein, the first connecting block 330 is provided with a protruding member 331, and the second connecting block 340 is provided with a through hole 341. The protruding member 331 passes through the through hole 341 so that when the driving component 400 drives the driving roller 610 to rotate and drives the conveyor belt 500 to reciprocate on the bracket 200, the sliding wheel 310 is simultaneously driven to reciprocate in the sliding groove 210.

[0048] Further, the sliding groove 210 includes a first sliding portion 211 and a second sliding portion 212. The second sliding portion 212 is connected to the first sliding portion 211, and the second sliding portion 212 is provided with a bending portion 213 that is bent relative to the first sliding portion 211. Wherein, the bending portion 213 is disposed at one end of the bracket 200 away from the target position.

[0049] Specifically, the bending portion 213 is disposed at one end of the bracket 200 away from the target position. When the pushing member 300 is in the second relative position, the pushing member 300 is located in the first sliding portion 211. When the pushing member 300 is in the first relative position, the pushing member 300 is located in the second sliding portion 212.

[0050] Furthermore, as Figure 1 and Figure 2 shown, the pushing device 100 is further provided with a mounting base 700. The pushing device 100 further includes a first switch member 710, a second switch member 720, and a third switch member 730 mounted on the mounting base 700. The first switch member 710 is disposed near the first sliding portion 211 and the target position. The second switch member 720 is disposed near the second sliding portion 212 and the target position. The third switch member 730 is disposed near the bending portion 213. The pushing member 300 is provided with a protruding portion 320 that protrudes outward from the end of the connecting portion. Wherein, when the protruding portion 320 approaches the first switch member 710, when the protruding portion 320 approaches the second switch member 720, or when the protruding portion 320 approaches the third switch member 730, the driving component 400 stops driving.

[0051] Specifically, the first switch member 710, the second switch member 720, and the third switch member 730 are all photosensitive sensors.

[0052] As Figure 1 shown, two photoelectric sensors are further disposed on both sides of the pushing device 100. The two photoelectric sensors are fixed on the mounting base 700 for detecting the lunch boxes above the bracket 200, and the two photoelectric switches are communicatively connected to the driving component 400.

[0053] On the other hand, an embodiment of the present utility model further provides a vending machine, which includes the pushing device 100 described in any of the above technical solutions.

[0054] In a specific embodiment, when the protruding portion 320 approaches the third switch member 730, the position where the pushing member 300 is located is the second relative position. At this time, the pushing device 100 waits to execute the pushing action; the conveying mechanism (not shown in the figure) of the vending machine transports the lunch box to the pushing device 100. When the photoelectric sensor senses that the lunch box approaches the pushing device 100, the driving component 400 starts to drive the driving roller 610 to rotate. While the conveyor belt 500 is driving, the connecting portion is driven together with the conveyor belt 500. When the protruding portion 320 approaches the second switch member 720, the driving component 400 stops rotating. When the lunch box is above the conveyor belt 500 and the conveying mechanism (not shown in the figure) for transporting the lunch box is far away from the pushing device 100, the driving component 400 starts to drive the driving roller 610 to rotate, the conveyor belt 500 continues to drive, and the connecting portion is driven together with the conveyor belt 500. When the protruding portion 320 approaches the first switch member 710, the pushing member 300 is located at the position of the first relative position, the pushing device 100 completes a pushing action on the lunch box, the driving component 400 stops rotating, and the lunch box is located at the target position. After the user takes away the lunch box from the target position, the driving component 400 starts to drive the driving roller 610 to rotate, transports the pushing member 300 to the second relative position and then stops driving, waiting for the next pushing instruction.

[0055] Although the present utility model is disclosed as above, the present utility model is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the scope defined by the claims.
