Description

Technical Field

[0001] This application relates to the field of vending equipment technology, and more particularly to a dispensing and return structure and a vending equipment. Background Technology

[0002] Individually packaged sheet items such as tissues, wet wipes, lottery tickets, and face masks require vending machines for sale. These machines are not limited by time or location and can be placed in public places such as shopping malls, subways, squares, and tourist attractions.

[0003] The vending machine consists of a main body and a mechanism inside the main body, which serves to deliver the sheet-like items. However, currently, if the sheet-like items remain at the vending slot after being delivered, they are easily contaminated or damaged by external factors, affecting future sales and causing resource waste. Utility Model Content

[0004] The first objective of this application is to provide a delivery return structure that aims to solve the technical problem that a sheet continuously located at the vending port of a vending machine can easily lead to resource waste.

[0005] To achieve the above objectives, the solution provided in this application is as follows:

[0006] A dispensing and retraction structure is applied to a vending machine, wherein the vending machine body is provided with a vending slot, and the dispensing and retraction structure is housed within the body. The dispensing and retraction structure includes:

[0007] The system comprises a first driving component, a first transmission assembly, and a conveying wheel assembly. The first driving component is connected to the conveying wheel assembly via the first transmission assembly to drive the conveying wheel assembly to rotate.

[0008] The conveyor wheel assembly is used to transport sheet-like objects along a first direction to the sales outlet;

[0009] The conveyor wheel assembly is also used to convey the sheet material back from the vending slot along a second direction into the machine body, wherein the first direction and the second direction are opposite.

[0010] A second objective of this application is to provide a vending machine, comprising:

[0011] The machine body is equipped with a vending machine;

[0012] The movement is housed within the body, and the movement includes a housing and the aforementioned delivery and return structure, which is mounted on the housing.

[0013] The send-back / return structure provided in this application has the following advantages:

[0014] The feed-and-retract structure comprises a first driving component, a first transmission assembly, and a conveyor wheel assembly. The first driving component transmits power to the conveyor wheel assembly via the first transmission assembly, enabling the conveyor wheel assembly to rotate and thus feed or retract the sheet material. The conveyor wheel assembly can feed the sheet material back into the machine body in a second direction, preventing the sheet material from remaining at the vending slot for an extended period. This avoids the sheet material being exposed to the vending machine for a long time and becoming contaminated or damaged, thus preventing impact on subsequent sales and resource waste. Furthermore, if the sheet material remains at the vending slot, maintenance is required, such as removing contaminated sheet material. Therefore, the feed-and-retract structure automatically retracts the sheet material, reducing maintenance difficulty and costs. Attached Figure Description

[0038] like Figure 1 and Figure 2 As shown, this application embodiment provides a delivery return structure 100 and a vending device 1. The vending device 1 can be a vending machine for selling various individually packaged sheet-like items 2. The sheet-like items 2 can be individually packaged sheet-like products such as tissues, wet wipes, lottery tickets, and red envelopes. The vending device 1 includes a mechanism 1a and a body 1b. The body 1b is provided with a vending slot 1c. The mechanism 1a is housed inside the body 1b. The mechanism 1a includes a machine compartment 200 and the delivery return structure 100 described in the first or second set of embodiments below. The delivery return structure 100 is installed on the machine compartment 200.

[0039] The following is in conjunction with the appendix Figure 1 To be continued Figure 7 This application provides a detailed description of some embodiments. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0040] First set of embodiments:

[0041] The send-back / return structure 100 provided in this embodiment can be referred to. Figures 1 to 4 .

[0042] like Figure 1 and Figure 2As shown, the delivery and retraction structure 100 of this embodiment includes a first driving member 10, a first transmission assembly 20, and a conveying wheel set 30. The first driving member 10 may be a motor. The first driving member 10 is connected to the conveying wheel set 30 through the first transmission assembly 20 to drive the conveying wheel set 30 to rotate. The conveying wheel set 30 is used to convey the sheet 2 forward along the first direction to the vending slot 1c. The conveying wheel set 30 is also used to convey the sheet 2 back from the vending slot 1c along the second direction into the body 1b. The first direction and the second direction are opposite.

[0043] The feed-back and return structure 100 of this embodiment is provided with a first driving member 10, a first transmission assembly 20, and a conveyor wheel set 30. The first driving member 10 transmits power to the conveyor wheel set 30 through the first transmission assembly 20, enabling the conveyor wheel set 30 to rotate. The conveyor wheel set 30 can convey the sheet 2 back into the machine body 1b along the second direction, preventing the sheet 2 from being located in the vending slot 1c for a long time. This avoids the sheet 2 being exposed outside the machine body 1b of the vending machine 1 for a long time and being contaminated or damaged, thus avoiding affecting the next sale and causing resource waste. Moreover, if the sheet 2 is always located in the vending slot 1c, it requires maintenance by staff, such as removing the contaminated sheet 2. Therefore, the feed-back and return structure 100 automatically returns the sheet 2, which can reduce the difficulty and cost of maintenance.

[0044] The first direction and the second direction can form a 180-degree angle, for example, the first direction and the second direction are opposite in direction. The first direction and the second direction can also form a 90-degree angle, for example, on a two-dimensional plane, the first direction can be rotated 90 degrees to the left or right to coincide with the second direction.

[0045] like Figures 1 to 3 As shown, in some application embodiments, the vending machine 1 has a storage area 201 in its compartment 200. The storage area 201 is used to place multiple stacked sheet-like items 2. The vending machine 1's mechanism 1a also includes a drive structure 300. The drive structure 300 is located below the storage area 201 and is used to convey the sheet-like items 2 (such as one or two sheet-like items 2) to move along a first direction. The conveyor wheel set 30 is used to receive the sheet-like items 2 conveyed by the drive structure 300 and convey the sheet-like items 2 to move along the first direction to the vending slot 1c.

[0046] In this embodiment, the drive structure 300 conveys the sheet 2 along the first direction to a position where the delivery and return structure 100 can receive the sheet 2. Then, the delivery and return structure 100 conveys the sheet 2 along the first direction to the sales outlet 1c. This not only completes one shipment but also avoids the phenomenon that the sheet 2 gets stuck at the sales outlet 1c when only one drive structure 300 is used to convey the sheet 2, causing the sheet 2 to move forward continuously.

[0047] Furthermore, the drive structure 300 includes a second drive member 301, a second transmission assembly 302, and a transmission wheel set 303. The second drive member 301 can be a motor. The second drive member 301 is connected to the transmission wheel set 303 via the second transmission assembly 302. The transmission wheel set 303 rotates under the drive of the second transmission assembly 302 to convey the sheet 2 along the first direction to a set position. The second drive member 301 is used to stop driving the second transmission assembly 302 when the sheet 2 reaches the set position, thereby stopping the drive of the transmission wheel set 303. Consequently, the transmission wheel set 303 will not continue to convey the sheet 2 from the storage area 201. The transmission wheel set 30 receives the sheet 2 conveyed to the set position by the transmission wheel set 303. The set position can be set according to actual needs, and can realize the position where the transmission wheel set 30 receives the sheet 2. For example, the set position is located on the transmission wheel set 30.

[0048] like Figures 1 to 3 As shown, in one embodiment, the conveyor wheel assembly 30 includes a first conveyor sub-wheel assembly 31 and a second conveyor sub-wheel assembly 32. The first conveyor sub-wheel assembly 31 and the second conveyor sub-wheel assembly 32 are arranged vertically at intervals, and a clamping space 33 is formed between the first conveyor sub-wheel assembly 31 and the second conveyor sub-wheel assembly 32. The set position is located in the clamping space 33. The first driving member 10 is connected to the first conveyor sub-wheel assembly 31 and the second conveyor sub-wheel assembly 32 respectively through the first transmission assembly 20, so as to transmit the driving force of the first driving member 10 to the first conveyor sub-wheel assembly 31 and the second conveyor sub-wheel assembly 32 respectively. Thus, under the drive of the first transmission assembly 20, the first conveyor sub-wheel assembly 31 and the second conveyor sub-wheel assembly 32 rotate respectively. The first conveyor sub-wheel assembly 31 is used to rub the upper surface of the sheet 2 when rotating, and the second conveyor wheel assembly 32 is used to rub the bottom surface of the sheet 2 when rotating, so that the sheet 2 moves forward in the first direction to the sales port 1c or moves back in the second direction to the clamping space 33.

[0049] In practical application, the first transmission assembly 20, under the action of the first driving member 10, can drive the first conveying wheel assembly 31 to rotate in a first clockwise direction (e.g., counterclockwise) and drive the second conveying wheel assembly 32 to rotate in a second clockwise direction (e.g., clockwise) to deliver the sheet 2 held between the first and second conveying wheel assemblies 31 and 32 along the first direction. Furthermore, when the first and second conveying wheel assemblies 31 and 32 cooperate to deliver the sheet 22 to the sales slot 1c, the sheet 2 is still held. The first transmission assembly 20, under the action of the first driving member 10, can also drive the first conveying wheel assembly 31 to rotate in a second clockwise direction and drive the second conveying wheel assembly 32 to rotate in the first clockwise direction to transfer the sheet 2 located at the sales slot 1c back into the clamping space 33 along the second direction, temporarily storing the sheet 2 in the clamping space 33. This allows the sheet 2 located in the clamping space 33 to be transferred to the sales slot 1c before the next sale, avoiding waste. Moreover, the sheet 2 located in the clamping space 33 is clamped by the first conveyor wheel group 31 and the second conveyor wheel group 32.

[0050] When the sheet 2 is located at the vending slot 1c, the sheet 2 can pass through the vending slot 1c so that part of the sheet 2 is inside the machine body 1b and the other part is exposed outside the machine body 1b, making it convenient for the user to take away the sheet 2.

[0051] like Figures 1 to 3 As shown, in one embodiment, the first conveying roller assembly 31 includes a first rotating shaft 311 and a first roller 312, and the second conveying roller assembly 32 includes a second rotating shaft 321 and a second roller 322. In a first direction (the direction of feeding out the sheet 2), the first rotating shaft 311 and the second rotating shaft 321 are staggered, so that the first roller 312 and the second roller 322 are vertically staggered, forming a clamping space 33 between the first roller 312 and the second roller 322; the first driving member 10 is connected to the first rotating shaft via the first transmission assembly 20. 311 and 321 are respectively driven to rotate; the first roller 312 is mounted on the first roller 311 and rotates with the first roller 311 to rub the upper surface of the sheet 2; the second roller 322 is mounted on the second roller 321 and rotates with the second roller 321 to rub the bottom surface of the sheet 2. Thus, under the clamping and conveying action of the first roller 312 and the second roller 322, the sheet 2 can move forward in the first direction to the sales port 1c or retreat in the second direction to the clamping space 33.

[0052] like Figures 1 to 3As shown, in some application embodiments, the mechanism 1a of the vending device 1 also includes a counterweight wheel 400. The two ends of the counterweight wheel 400 are movably connected to the two sides of the machine compartment 200. The counterweight wheel 400 is used to press against the upper surface of the sheet 2 to keep the sheet 2 flat and prevent the sheet 2 from wrinkling.

[0053] like Figures 2 to 4 As shown, in one embodiment, the first transmission assembly 20 includes a transmission shaft 21, a first transmission wheel set 22, and a second transmission wheel set 23. The first driving member 10 drives the first transmission wheel set 22 to rotate. The second transmission wheel set 23 is connected to the first transmission wheel set 22 via the transmission shaft 21 to rotate under the drive of the transmission shaft 21. The second transmission wheel set 23 is connected to the first conveyor wheel set 31 and the second conveyor wheel set 32 ​​respectively.

[0054] In this embodiment, the power of the first driving member 10 is transmitted sequentially to the second driving member 23 via the first transmission wheel set 22 and the transmission shaft 21, and then transmitted by the second transmission wheel set 23 to the first conveyor wheel set 31 and the second conveyor wheel set 32 ​​respectively, so as to drive the first conveyor wheel set 31 and the second conveyor wheel set 32 ​​to rotate respectively.

[0055] like Figures 2 to 4 As shown, in one embodiment, the first driving member 10 and the second driving member 301 are respectively disposed on both sides of the housing 200 and are offset along the first direction; in the axial direction of the transmission shaft 21, the first transmission wheel set 22 and the second transmission wheel set 23 are spaced apart. The first transmission wheel set 22 includes an output gear 221 and a reduction gear 222. The first driving member 10 drives the output gear 221 to rotate. The reduction gear 222 is mounted on the transmission shaft 21 and meshes with the output gear 221. Under the action of the output gear 221, the reduction gear 222 drives the transmission shaft 21 to rotate. The reduction gear 222 can increase the torque to increase the power transmitted to the transmission shaft 21 and the second transmission wheel set 23, thereby increasing the force driving the first conveyor wheel set 31 and the second conveyor wheel set 32 ​​to rotate, so as to realize the rotation of the first conveyor wheel set 31 and the second conveyor wheel set 32 ​​respectively.

[0056] Furthermore, the first driving component 10, the first transmission wheel set 22, and the second transmission wheel set 23 are arranged on the same side.

[0057] like Figures 2 to 4As shown, in one embodiment, the second transmission wheel assembly 23 includes a first transmission wheel 231, a second transmission wheel 232, a third transmission wheel 233, and a first annular transmission member 234. The first transmission wheel 231 is mounted on the transmission shaft 21 to rotate with the transmission shaft 21. The first transmission wheel 231 includes a first part 2311 and a second part 2312, which are connected sequentially in the axial direction of the transmission shaft 21. The outer peripheral surface of the first part 2311 and the outer peripheral surface of the second transmission wheel 232 are both provided with external teeth, so that the second transmission wheel 232 meshes with the first part 2311, thereby rotating under the drive of the first part 2311. The second transmission wheel 232 is driven to the second conveyor wheel assembly 32. Under the action of the first part 2311, the second transmission wheel 232 drives the second conveyor wheel assembly 32 to rotate. Specifically, the second transmission wheel 232 is driven to the second conveyor wheel assembly 32. The second drive wheel 232 is connected to the second shaft 321, and under the transmission action of the first part 2311, the second drive wheel 232 drives the second shaft 321 to rotate, thereby driving the second roller 322 to rotate. The third drive wheel 233 is connected to the first conveyor wheel assembly 31. The first annular drive member 234 is wound around the third drive wheel 233 and the second part 2312, so that under the action of the first annular drive member 234, the third drive wheel 233 drives the first conveyor wheel assembly 31 to rotate. That is, the second part 2312 drives the third drive wheel 233 to rotate through the first annular drive member 234, thereby driving the third drive wheel 233 to rotate. Specifically, the third drive wheel 233 is connected to the first shaft 311, so that under the transmission action of the second part 2312, the first annular drive member 234 drives the third drive wheel 233 to rotate, thereby driving the first shaft 311 to rotate, and then driving the first roller 312 to rotate.

[0058] For example, the first transmission wheel 231 is a compound gear, the second transmission wheel 232 is a gear, the third transmission wheel 233 is a synchronous pulley, the first annular transmission member 234 is a synchronous belt, and the second transmission wheel group 23 also includes a tensioning wheel 235. The tensioning wheel 235 is rotatably mounted on the machine compartment 200, and the outer circumferential surface of the tensioning wheel 235 abuts against the first annular transmission member 234 to tension the first annular transmission member 234.

[0059] Combination Figure 3 and Figure 4In another embodiment, the second transmission wheel set 23 includes a first transmission gear (not shown), a second transmission gear (not shown), a fourth transmission wheel (not shown), a fifth transmission wheel (not shown), and a second annular transmission member (not shown). The fourth and fifth transmission wheels can both be synchronous pulleys, and the second annular transmission member can be a synchronous belt. The first transmission gear is mounted on one end of the transmission shaft 21 to follow the rotation of the transmission shaft 21. The second transmission gear is driven to the second conveyor wheel set 32. The second transmission gear meshes with the first transmission gear so that, under the action of the first transmission gear, the second transmission gear drives the second conveyor wheel set 32 ​​to rotate. Specifically, the second transmission gear is driven to the end of the second rotating shaft 321 away from the first transmission wheel set 22 so that, under the action of the first transmission gear, the second transmission gear drives the second rotating shaft 321 to rotate.

[0060] Furthermore, the fourth transmission wheel is installed at the other end of the transmission shaft 21 to rotate with the transmission shaft 21. It can be understood that the second transmission gear and the fourth transmission wheel are respectively connected to the two axial ends of the transmission shaft 21, and the fourth transmission wheel is arranged on the same side as the first driving member 10. The fifth transmission wheel is driven to the first conveying sub-wheel group 31, and the second annular transmission member is wound around the fourth transmission wheel and the fifth transmission wheel. The fourth transmission wheel drives the fifth transmission wheel to rotate through the second annular transmission member. Under the action of the second annular transmission member, the fifth transmission wheel drives the first conveying sub-wheel group 31 to rotate. Specifically, the fifth transmission wheel is driven to the first rotating shaft 311, so that under the action of the second annular transmission member, the fifth transmission wheel drives the first rotating shaft 311 to rotate.

[0061] like Figure 1 and Figure 2 As shown, and in combination Figure 5 In one implementation, the delivery and retraction structure 100 further includes a detection element 40 and a control board 50. The detection element 40 can be a sensor, such as a reflective sensor, or it can be a camera. The control board 50 is mounted on the machine compartment 200 of the vending machine 1. The first drive element 10 is electrically connected to the control board 50, and the detection element 40 is also electrically connected to the control board 50. When the detection element 40 continuously detects that the sheet-like object 2 is located at the vending slot 1c, under the drive of the first drive element 10, the first transmission assembly 20 drives the conveyor wheel set 30 to convey the sheet-like object 2 back along the second direction into the machine body 1b. For example, when the detection element 40 senses or captures the sheet-like object 2 for a period of time (e.g., 1 to 2 minutes, the specific time can be set as needed), the control board 50 controls the first drive element 10 to drive the first transmission assembly 20 to move, thereby driving the conveyor wheel set 30 to convey the sheet-like object 2 back along the second direction into the machine body 1b.

[0062] In one specific embodiment, the detection element 40 is disposed on the control plate 50. For example, the detection element 40 is mounted on the bottom surface of the control plate 50, located above the clamping space 33; or, the detection element 40 may not be disposed on the control plate 50. For example, the detection element 40 is disposed on the machine compartment 200, located below the clamping space 33. In specific applications, when the detection element 40 senses or captures the sheet-like object 2 for a period of time (e.g., 1 to 2 minutes, the specific time can be set as needed), the conveying wheel assembly 30 conveys the sheet-like object 2 back along the second direction into the machine body 1b. Furthermore, it can also be configured that when the detection element 40 detects that the sheet-like object 2 has moved to a set position along the first direction, the drive structure 300 stops conveying the sheet-like object 2 located in the storage area 201.

[0063] In another specific embodiment, the detection element 40 is disposed on the body 1b and is used to sense or photograph the situation in front of the vending machine 1 body 1b. When the detection element 40 senses or photographs the sheet 2 located at the vending slot 1c for a period of time but there is no one in front of the vending machine, the conveyor wheel assembly 30 begins to convey the sheet 2 back into the body 1b in the second direction.

[0064] like Figures 1 to 3 As shown, in some other application embodiments, the mechanism 1a of the vending machine 1 further includes a linkage mechanism 500 and a door 600. The linkage mechanism 500 can be located on the side of the machine compartment 200 away from the first driving member 10, or it can be located on the same side as the first driving member 10. The door 600 is rotatably connected to the machine compartment 200. The linkage mechanism 500 is provided with a linkage part 501, and the door 600 is provided with a swing part 601. Driven by the linkage mechanism 500, the linkage part 501 moves along a fourth direction (e.g., downward) to reach a set contact position and press against the swing part 601 to swing, causing the door 600 to swing along a third direction (e.g., upward) to expose the vending slot 1c. Driven by the linkage mechanism 500, the linkage part 501 can also move along a third direction to release the swing part 601 after passing the set contact position, causing the door 600 to swing along the fourth direction to cover the vending slot 1c.

[0065] Furthermore, the linkage mechanism 500 includes a guide member 502, a sliding member 503, and a linkage gear 504. The sliding member 503 is slidably disposed on the guide member 502. The linkage gear 504 is driven to the power output end of the second conveyor wheel assembly 32, so as to rotate under the drive of the second conveyor wheel assembly 32. Specifically, the linkage gear 504 is driven to the power output end of the second rotating shaft 321, so as to rotate under the transmission action of the second rotating shaft 321. The linkage part 501 is disposed on the sliding member 503. The sliding member 503 is also provided with transmission teeth (not shown in the figure). The transmission teeth are annular internal teeth. The linkage gear 504 meshes with the transmission teeth of the sliding member 503. When the linkage gear 504 rotates, it drives the sliding member 503 to slide on the guide member 502. Thus, when the sliding member 503 slides, it can drive the linkage part 501 to move, so as to press against or release the swing part 601.

[0066] like Figures 1 to 3 As shown, in another embodiment, the conveyor wheel set 30 is also used to drive the linkage mechanism 500 of the vending machine 1. Specifically, the second conveyor wheel set 32 ​​is driven by the linkage gear 504 of the linkage mechanism 500. The linkage mechanism 500 is provided with a linkage part 501. When the conveyor wheel set 30 conveys the sheet 2 back along the second direction, the linkage mechanism 500, under the action of the conveyor wheel set 30, drives the linkage part 501 to move along the third direction to the set contact position, at which point the sheet 2 is completely retracted into the machine body 1b. In this way, during the closing process of the door 600, it is possible to observe whether the linkage part 501 returns to the set contact position along the third direction to determine whether the sheet 2 has been retracted into the machine body 1b.

[0067] Second set of embodiments:

[0068] The send-back / return structure 100 provided in this embodiment can be referred to. Figures 5 to 7 .

[0069] The main difference between this embodiment and the first set of embodiments lies in the different structure of the first transmission component 20, as detailed below:

[0070] like Figure 5 and Figure 6 As shown, in one embodiment, the first transmission assembly 20 includes a coupling member (not shown) and a gear set 24. The coupling member can be a coupling. The first driving member 10 is connected to one end of the second rotating shaft 321 through the coupling member to drive the second rotating shaft 321 to rotate, thereby driving the second roller 322 to rotate. The other end of the second rotating shaft 321 is connected to the first rotating shaft 311 through the gear set 24 to drive the first rotating shaft 311 to rotate, thereby driving the first roller 312 to rotate.

[0071] like Figures 5 to 7As shown, in one embodiment, the gear set 24 includes a first gear 241, a second gear 242, a third gear 243, and a fourth gear 244. The first gear 241 is rotatably connected to the side of the housing 200 away from the first driving member 10. Specifically, a mounting shaft 700 protrudes from the side of the housing 200 away from the first driving member 10, and the first gear 241 is rotatably mounted on the mounting shaft 700. The second gear 242 is connected to the end of the second rotating shaft 321 away from the first driving member 10 and meshes with the first gear 241. Under the action of the second rotating shaft 321, the second gear 242 drives the first gear 241 to rotate. Further, the third gear 243 is connected to the first rotating shaft 311, and the fourth gear 244 is located between the first gear 241 and the third gear 243, and meshes with both the first gear 241 and the third gear 243 respectively. Under the transmission action of the first gear 241, the fourth gear 244 drives the third gear 243 to rotate, thereby driving the first rotating shaft 311 to rotate, and thus driving the first roller 312 to rotate. In the axial direction of the first gear 241 (e.g.) Figure 7 On x), the fourth gear 244 is misaligned with the second gear 242.

[0072] Furthermore, the first drive component 10 and the second drive component 301 are arranged on the same side, and the first drive component 10 and the gear set 24 are located on both sides of the machine compartment 200, which is a reasonable arrangement.
