Description

Technical Field

[0001] This application relates to the field of vending equipment technology, and in particular to a vending machine door structure and 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 includes a mechanism for conveying sheet-like products and a body for housing the mechanism. The body has a vending slot, and a door is rotatably mounted on the vending slot to cover or expose it. During dispensing, the sheet-like product is conveyed by the mechanism, pushing the door open. However, this method of opening the door has a low degree of automation. Utility Model Content

[0004] The first objective of this application is to provide a door structure that addresses the technical problem of low automation in current door opening methods.

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

[0006] A door structure is applied to a vending machine, the vending machine having a vending slot, the core of the vending machine including a machine compartment and a drive structure, the drive structure being used to move sheet-like objects, the door structure comprising:

[0007] The door is movably connected to the machine bay;

[0008] The linkage mechanism is used for transmission connection of the drive structure;

[0009] Driven by the drive structure, the linkage mechanism drives the door to move along the first direction to open the door and expose the sales opening.

[0010] Driven by the drive structure, the linkage mechanism also drives the door to move in the second direction to close the door and cover the vending opening.

[0011] The first direction and the second direction are opposite.

[0012] A second objective of this application is to provide a vending machine, comprising:

[0013] The machine body is equipped with a vending machine;

[0014] The movement is housed within the body. The movement includes a housing, a drive structure, and the aforementioned door structure. Both the drive structure and the door structure are located on the housing.

[0015] The door structure provided in this application has the following beneficial effects:

[0016] The door structure is used in the mechanism of vending equipment. The door structure is equipped with a linkage mechanism and a door body. The linkage mechanism can move under the drive of the drive structure with the function of conveying sheet-like objects, and drive the door body to move in an active linkage manner under the action of the drive structure, such as driving the door body to swing up and down or push and pull up and down to open and close the door body. That is, the same drive structure can be used to both convey sheet-like objects and drive the linkage mechanism to move to drive the door body to open and close. The whole process does not require an additional drive mechanism to drive the linkage mechanism to drive the door body to open and close.

[0017] Moreover, this embodiment uses an automatic door opening method to expose the vending slot and an automatic door closing method to cover the vending slot, which can improve the automation level of opening and closing the door. Compared with the method of relying on a sheet to push open the door, the method of opening the door is more convenient and can avoid the phenomenon of the sheet wrinkling or deforming during the process of pushing the door open.

[0036] like Figure 1 and Figure 2 As shown, this application embodiment provides a door structure 100 and a vending device 1. The vending device 1 can be a vending machine used to sell 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 door structure 100, a drive structure 200, and a machine compartment 300. The drive structure 200 and the door structure 100 are both disposed on the machine compartment 300. The drive structure 200 is used to move the sheet-like items 2.

[0037] Furthermore, the door structure 100 includes a door body 10 and a linkage mechanism 20. The door body 10 is movably connected to the machine compartment 300. The drive structure 200 is connected to the linkage mechanism 20. Under the drive of the drive structure 200, the linkage mechanism 20 drives the door body 10 to move in a first direction to open the door body 10 and expose the sales opening 1c. Under the drive of the drive structure 200, the linkage mechanism 20 also drives the door body 10 to move in a second direction to close the door body 10 and cover the sales opening 1c. The first direction and the second direction are opposite.

[0038] In this embodiment, the vending machine 1's door structure 100 is equipped with a linkage mechanism 20 and a door body 10. The linkage mechanism 20 can move under the drive of the drive structure 200 which has the function of conveying sheet-like objects 2, and drive the door body 10 to move in an active linkage manner under the action of the drive structure 200, such as driving the door body 10 to swing up and down or to push and pull up and down, so as to open and close the door body 10. That is, the same drive structure 200 can both convey sheet-like objects 2 and drive the linkage mechanism 20 to move to drive the door body 10 to open and close. The whole process does not require an additional drive mechanism to drive the linkage mechanism 20 to drive the door body 10 to open and close.

[0039] Moreover, this embodiment uses an automatic door opening method to expose the vending slot 1c and an automatic door closing method to cover the vending slot 1c, which can improve the automation of opening and closing the door. Compared with the method of relying on the sheet 2 to push open the door 10, the method of opening the door 10 is more convenient and can avoid the phenomenon of the sheet 2 wrinkling or deforming during the process of pushing the door open.

[0040] like Figure 1 and Figure 2 As shown, in some application embodiments, the drive structure 200 is used to move the sheet 2 along a third direction to the vending slot 1c. The drive structure 200 is also used to move the sheet 2 located at the vending slot 1c back along a fourth direction. The third direction and the fourth direction are opposite, and the third direction intersects with the first direction. It can be understood that 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 vertical direction. The third direction and the fourth direction can also form a 180-degree angle, for example, the third direction and the fourth direction are opposite in front-back direction. The door 10 is used to open before the sheet 2 moves to the vending slot 1c to expose the vending slot 1c; the door 10 is also used to close after the sheet 2 returns to the vending device 1 to cover the vending slot 1c. Specifically, the sheet 2 can return from the vending slot 1c back into the body 1b.

[0041] In this embodiment, the door 10 is opened before the sheet 2 reaches the vending slot 1c and closed after the sheet 2 has completely returned to the vending device 1. This can prevent the door 10 from affecting the delivery and return of the sheet 2, and also prevent the door 10 from damaging the sheet 2 during the opening and closing process.

[0042] like Figure 1 , Figure 2 and Figure 4 As shown, in some embodiments, the linkage mechanism 20 is provided with a linkage part 30, and the door body 10 is provided with a swing part 40. Under the drive of the linkage mechanism 20, the linkage part 30 moves along the second direction to reach a set contact position and press against the swing part 40 to swing, so that the door body 10 swings along the first direction to expose the sales opening 1c. For example, the linkage part 30 moves downward under the drive of the linkage mechanism 20 to reach the set contact position to contact the swing part 40, and continues to move downward to press against the swing part 40 to make the swing part 40 swing downward, so that the door body 10 swings upward to expose the sales opening 1c. Under the drive of the linkage mechanism 20, the linkage part 30 can also move along the first direction to release the swing part 40 after passing the set contact position, so that the door body 10 swings along the second direction to cover the sales opening 1c. For example, the linkage part 30 moves upward under the drive of the linkage mechanism 20 to reach the set contact position, and continues to move upward to release the swing part 40, so that the door body 10 swings downward to reset under the action of gravity and covers the sales opening 1c.

[0043] The contact position can be the position of the swing part 40 when the door 10 covers the vending opening 1c and is supported by the machine compartment 300.

[0044] like Figures 1 to 4 As shown, in some application embodiments, the machine compartment 300 is provided with a storage area 301 for placing multiple stacked sheet-like items 2. The mechanism 1a also includes a first drive component 400, a first transmission component 500, and a transmission wheel set 600. The first drive component 400 may be a motor. The first drive component 400 is connected to the transmission wheel set 600 through the first transmission component 500. The transmission wheel set 600 rotates under the drive of the first transmission component 500 to convey the sheet-like items 2 in the storage area 301 to move along a third direction. The drive structure 200 receives the sheet-like items 2 conveyed by the transmission wheel set 600 and conveys the sheet-like items 2 to the vending slot 1c along a third direction.

[0045] Furthermore, the drive structure 200 includes a second drive member 201, a first conveyor wheel assembly 202, a second conveyor wheel assembly 203, and a second transmission assembly 204. The first conveyor wheel assembly 202 and the second conveyor wheel assembly 203 are arranged vertically at intervals, and a clamping space 205 is formed between them. The rotation directions of the first conveyor wheel assembly 202 and the second conveyor wheel assembly 203 are opposite. The second drive member 201 is connected to the first conveyor wheel assembly 202 and the second conveyor wheel assembly 203 respectively via the second transmission assembly 204. Two conveyor roller sets 203 transmit the driving force of the second drive member 201 to the first conveyor roller set 202 and the second conveyor roller set 203 respectively. Under the drive of the second transmission assembly 204, the first conveyor roller set 202 and the second conveyor roller set 203 rotate respectively. The first conveyor roller set 202 rubs against the upper surface of the sheet-like object 2 during rotation, and the second conveyor roller set 203 rubs against the bottom surface of the sheet-like object 2 during rotation, so that the sheet-like object 2 moves forward in a third direction to the sales opening 1c or retracts in a fourth direction to the clamping space 205. The linkage mechanism 20 is connected to the power output end of the second conveyor roller set 203, and moves under the drive of the second conveyor roller set 203, thereby driving the door body 10 to move.

[0046] In practical application, the second driving component 201 rotates clockwise to drive the second transmission assembly 204 to move, causing the second conveying wheel assembly 203 to rotate in a second clockwise (e.g., clockwise) direction to convey the sheet material 2 to move in a third direction. During this process, the second conveying wheel assembly 203 also drives the linkage mechanism 20 to move, thereby enabling the linkage mechanism 20 to drive the linkage part 30 to move in a second direction (e.g., downward). When the linkage part 30 moves in the second direction to the set contact position, the door 10 is in the first position. The door 10 in the first position is placed on the machine compartment 300 and covers the vending slot 1c. Subsequently, the linkage part 30 continues to move in the second direction from the set contact position to press against the swing part 40 to swing in the second direction, thereby causing the door 10 to swing in the first direction (e.g., upward), thus opening the door 10 and revealing the vending slot 1c. During the process of waiting for the sheet material 2 to arrive at the vending slot 1c and waiting for the sheet material 2 to be taken away, the door 10 can remain in the second position, that is, the door 10 remains open.

[0047] Moreover, after the sheet 2 is removed, the second drive member 201 can reverse the drive of the second transmission assembly 204 to move, causing the second conveyor wheel assembly 203 to rotate in the first clockwise (e.g., counterclockwise) direction. The linkage mechanism 20 moves under the drive of the second conveyor wheel assembly 203 to drive the linkage part 30 to move in the first direction (e.g., upward), so that the linkage part 30 gradually moves back to approach the set contact position. During this process, the door body 10 can move from the second position in the second direction (e.g., downward) under its own gravity. After the linkage part 30 moves in the first direction to reach the set contact position, it will continue to move in the first direction to release the swing part 40 after passing the set contact position. The door body 10 continues to move slightly in the second direction under the action of gravity, returning to the first position and covering the sales opening 1c.

[0048] When the second driving member 201 reverses and drives the second transmission assembly 204 to move, if there is a sheet 2 at the vending slot 1c, the first conveying wheel group 202 and the second conveying wheel group 203 can rub up and down against the surface of the sheet 2 to convey the sheet 2 back into the body 1b. When the linkage part 30 moves along the first direction to the set contact position, the sheet 2 is completely retracted into the body 1b.

[0049] like Figure 2 , Figure 3 and Figure 4As shown, in some embodiments, the door 10 has two sides 11, which are located on both sides of the cabin 300. One side 11 is adjacent to the linkage mechanism 20, and the other is away from the linkage mechanism 20. The door structure 100 also includes two connecting shafts 50, with the two sides 11 corresponding to the two connecting shafts 50. The side 11 is hinged to the cabin 300 through the connecting shafts 50. The swinging part 40 is disposed on the side 11 adjacent to the linkage mechanism 20. The swinging part 40 is used to drive the side 11 adjacent to the linkage mechanism 20 to rotate under the pressure of the linkage part 30, so as to drive the door 10 to swing. The side 11 away from the linkage mechanism 20 rotates under the drive of the door 10.

[0050] Furthermore, the door structure 100 also includes an elastic element 60, which may be a torsion spring. The elastic element 60 is arranged around at least one connecting shaft 50. Specifically, the elastic element 60 is arranged around the side 11 adjacent to the linkage mechanism 20. The elastic element 60 is used to apply a force in a second direction to the door body 10.

[0051] In practical applications, one torsion arm of the elastic element 60 is connected to the machine compartment 300, and the other torsion arm of the elastic element 60 presses against the side 11 of the adjacent linkage mechanism 20. When the linkage part 30 moves along the first direction and passes through the set contact position, it releases the swing part 40. Under the downward pressure of the other torsion arm of the elastic element 60, the door 10 swings along the second direction to return to the first position and cover the vending slot 1c. The door 10 can also be kept in the first position under the action of the elastic element 60 to ensure the stability of closing the door.

[0052] like Figure 2 and Figure 5 As shown, in some embodiments, the linkage mechanism 20 includes a guide member 21, a sliding member 22, and a linkage gear 23. The sliding member 22 is slidably disposed on the guide member 21. The linkage gear 23 is driven to the power output end of the drive structure 200 so as to rotate under the drive of the drive structure 200. Specifically, the linkage gear 23 is driven to the power output end of the second conveyor wheel assembly 203 so as to rotate under the drive of the second conveyor wheel assembly 203. The linkage part 30 is disposed on the sliding member 22. The sliding member 22 is also provided with a transmission tooth 24. The linkage gear 23 meshes with the transmission tooth 24. When the linkage gear 23 rotates, it drives the sliding member 22 to slide on the guide member 21 so as to drive the linkage part 30 to move and press against or release the swing part 40.

[0053] like Figure 1 , Figure 3 and Figure 5As shown, in some embodiments, the first conveying roller assembly 202 includes a first rotating shaft 2021 and a first roller 2022, and the second conveying roller assembly 203 includes a second rotating shaft 2031 and a second roller 2032. In a third direction (the direction of feeding the sheet 2), the first rotating shaft 2021 and the second rotating shaft 2031 are staggered, so that the first roller 2022 and the second roller 2032 are vertically staggered, and a clamping space 205 is formed between the first roller 2022 and the second roller 2032; the second driving member 201 is connected to the second driving member 2032 through the second transmission assembly 204. A first rotating shaft 2021 and a second rotating shaft 2031 are provided to drive the first rotating shaft 2021 and the second rotating shaft 2031 to rotate, respectively. A first roller 2022 is mounted on the first rotating shaft 2021 and rotates with the first rotating shaft 2021 to rub the upper surface of the sheet 2. A second roller 2032 is mounted on the second rotating shaft 2031 and rotates with the second rotating shaft 2031 to rub the bottom surface of the sheet 2. Thus, under the action of the first roller 2022 and the second roller 2032, the sheet 2 can move forward in a third direction to the sales outlet 1c or retract in a fourth direction to the clamping space 205. A linkage gear 23 is connected to the power output end of the second rotating shaft 2031 to rotate under the transmission action of the second rotating shaft 2031, thereby driving the sliding member 22 to slide on the guide member 21, and then driving the linkage part 30 to move to press against or release the swing part 40.

[0054] In practical applications, the rotation direction of the linkage gear 23 is the same as the rotation direction of the second conveyor wheel assembly 203, that is, the rotation direction of the linkage gear 23 is the same as the rotation direction of the second rotating shaft 2031.

[0055] like Figure 2 and Figure 3 As shown, in some embodiments, the linkage mechanism 20 is located on the side of the engine compartment 300 away from the second drive member 201, while in other embodiments, the linkage mechanism 20 is located on the same side as the second drive member 201.

[0056] like Figure 2 , Figure 3 and Figure 5As shown, in some embodiments, the linkage mechanism 20 and the second driving member 201 are respectively located on both sides of the housing 300. The guide member 21 includes an annular plate 211, and the sliding member 22 includes a mounting body 221 and an annular body 222. The annular body 222 is rotatably mounted on the housing 300 via the mounting body 221, so that the annular body 222 can rotate relative to the housing 300. The transmission gear 24 is an annular internal gear, and the transmission gear 24 is located on the side of the annular body 222 facing the mounting body 221. The linkage part 30 is located on the side of the annular body 222 away from the mounting body 221. The transmission gear 24 of the annular body 222 meshes with the linkage gear 23, so that under the drive of the linkage gear 23, the annular body 222 slides on the guide member 21, thereby driving the linkage part 30 located on the annular body 222 to move. Specifically, in conjunction with Figure 4 and Figure 5 The annular body 222 is provided with a notch 223. The notch 223 forms a linkage part 30 on the inner wall of the annular body 222 in the circumferential direction. The swing part 40 can be a protruding post on the door body 10. The extension direction of the protruding post is the length direction of the door body 10. The protruding post is parallel to the connecting shaft 50.

[0057] Furthermore, the machine compartment 300 has a first side 300a and a second side 300b, which are arranged adjacent to each other. The door 10 is located between the first side 300a and the vending machine 1c, and the linkage mechanism 20 is arranged on the second side 300b.

[0058] like Figure 2 , Figure 3 and Figure 5 As shown, in some embodiments, the mounting body 221 includes a mounting portion 2211, a first connecting rod 2212, and a second connecting rod 2213. The annular body 222 is located on the side of the guide member 21 facing the housing 300, while the first connecting rod 2212 and the second connecting rod 2213 are located on the side of the guide member 21 away from the housing 300, and the first connecting rod 2212 and the second connecting rod 2213 are angled together. The mounting portion 2211 is rotatably mounted on the housing 300, and the annular body 222 is connected to the mounting portion 2211 via the first connecting rod 2212 and the second connecting rod 2213, enabling the annular body 222 to rotate relative to the housing 300. For example, the guide member 21 may be an annular gear ring, and the sliding member 22 may be a gear ring baffle.

[0059] like Figures 1 to 3 As shown, and in combination Figure 5In some embodiments, when the linkage 30 is in the set contact position, the first connecting rod 2212 is located below the second connecting rod 2213; the machine compartment 300 is provided with a detection element (not shown) and a control board (not shown), the control board is electrically connected to the detection element, and the drive structure 200 is electrically connected to the control board. Specifically, the control board is electrically connected to the second drive element 201, and the detection element and the linkage mechanism 20 are both disposed on the second side 300b; the first connecting rod 2212 has a protrusion 25 on the side away from the annular body 222, and the first connecting rod 2212 drives the protrusion 25 to move under the drive of the annular body 222; during the opening of the door 10, the detection... When the measuring component detects the protrusion 25, the drive structure 200 stops driving the linkage mechanism 20 to move. Specifically, the second drive component 201 stops driving the second transmission component 204 to move, thereby stopping the rotation of the second conveyor wheel group 203, and further stopping the movement of the linkage gear 23 of the linkage mechanism 20, so as to keep the door 10 in the open state. At the same time, the second transmission component 204 also stops driving the first conveyor wheel group 202 to rotate, so as to stop the conveying of the sheet 2 to move towards the vending slot 1c. Thus, the sheet 2 can remain at the vending slot 1c for a period of time (such as 1 to 2 minutes, which can be set as needed), making it convenient for the user to take away the sheet 2.

[0060] 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.

[0061] Combination Figures 2 to 4 In other embodiments, the guide member 21 and the second drive member 201 are disposed on the same side. Both the guide member 21 and the sliding member 22 extend along the height direction of the housing 300, and the sliding member 22 is slidably connected to the guide member 21. In specific applications, the sliding member 22 moves up and down under the drive of the linkage gear 23, thereby pressing against or releasing the swing part 40 to open or close the door 10. For example, the guide member 21 can be a guide rail, and the sliding member 22 can be a rack meshing with the linkage gear 23.

[0062] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural transformations made based on the content of the specification and drawings of this application under the concept of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
