Description

Technical Field

[0002] In the vending machines on the market, the bagged goods transmission structure includes a set of main transmission structure and slave transmission structure. The main transmission structure and the slave transmission structure are brought close to each other through elastic pressure, and the space between the main transmission structure and the slave transmission structure can transmit the bagged goods.

[0003] This bagged commodity transmission structure is only suitable for the transmission of bagged commodities with smaller thickness and more uniform thickness. When the bagged commodities are thicker, less uniform, or softer, the power of the main transmission structure cannot be transmitted to the slave transmission structure through the bagged commodities, and it is easy to slip and jam. For example, the transmission of Chinese medicine beverage bags in vending machines has the above problem. Summary of the invention

[0048] In order to facilitate the understanding of the present application, the present application is described in more detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that when an element is described as "fixed to" another element, it can be directly on the other element, or there can be one or more centered elements therebetween. When an element is described as "connected to" another element, it can be directly connected to the other element, or there can be one or more centered elements therebetween. The terms "vertical", "horizontal", "left", "right", "inside", "outside" and similar expressions used in this specification are for illustrative purposes only.

[0049] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used in this specification includes any and all combinations of one or more of the related listed items.

[0050] In addition, the terms first, second, third, etc. in the specification and claims are only used for the purpose of describing the same technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated, nor necessarily describing the order or time sequence. The terms are interchangeable where appropriate. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0051] Similarly, the terms "fixed" and "connected" used in the specification and claims should not be construed as limited to direct connection. Therefore, the expression "device A is connected to device B" should not be limited to a device or system in which device A is directly connected to device B, but means that there is a path between device A and device B, which may be a path including other devices or tools.

[0052] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0053] Please refer to Figure 1 A commodity transmission device 100 includes a first transmission component 10, a transmission component 20, a second transmission component 30, a driving component 40 and an elastic element 50; the driving component 40 is connected to the second transmission component 30 through the transmission component 20, and the second transmission component 30 is used for transmission operation; the transmission surface of the first transmission component 10 is opposite to the transmission surface of the second transmission component 30, and the transmission component 20 can be unfolded or retracted so that the transmission surface of the second transmission component 30 can be close to or away from the transmission surface of the first transmission component 10; the elastic element 50 is connected to the second transmission component 30, and the elastic element 50 is used to push the second transmission component 30 to approach the first transmission component 10.

[0054] In the commodity transmission device 100 of this embodiment, the driving component 40 can drive the second transmission component 30 to transmit. The first transmission component 10 can also be driven by the driving component 40, and can also be driven by other driving structures. It can also be a non-driven transmission. When the first transmission component 10 and the second transmission component 30 transmit commodities, the first transmission component 10 is a driven transmission, and the second transmission component 30 is an active transmission. When transmitting commodities, the elastic element 50 can push the second transmission component 30 to approach the first transmission component 10, and the first transmission component 10 and the second transmission component 30 generate a certain extrusion force on the commodities, and the extrusion force can provide a static friction force on the commodities. When the first transmission component 10 and the second transmission component 30 are transmitting and operating, the static friction force can form a transmission force on the commodities. When the first transmission component 10 and the second transmission component 30 are transmitting and operating, it does not affect the elastic element 50 pushing the second transmission component 30 to approach the first transmission component 10. Under the action of the elastic element 50, the first transmission component 10 and the second transmission component 30 can adapt to commodities with larger thickness and uneven thickness. During the commodity transmission process, there will be no uneven force, and slipping and jamming can be avoided.

[0055] It can be understood that, in some embodiments, the number of drive components 40 can also be two or more sets, and the first transmission component 10 and the second transmission component 30 are respectively driven by at least one set of drive components 40. For example, one drive component 40 is connected to the first transmission component 10 through transmission, and the other drive component 40 is connected to the second transmission component 30 through the transmission component 20.

[0056] Please refer to Figure 2 In some embodiments, the commodity transmission device 100 further includes a housing 101, and the first transmission component 10, the second transmission component 30, the drive component 40, the elastic element 50, the transmission component 20 and other structures are all installed in the housing 101. It can be understood that in some embodiments, the housing 101 can also be omitted, and the first transmission component 10, the second transmission component 30, the drive component 40, the elastic element 50, the transmission component 20 and other structures can be directly installed on a certain installation station.

[0057] Please refer to Figures 3 to 5In one embodiment, the driving component 40 is connected to the first transmission component 10 to drive the first transmission component 10 to transmit. In this embodiment, a set of driving components 40 can simultaneously drive the first transmission component 10 and the second transmission component 30 through the transmission component 20, which can reduce the number of driving components 40, simplify the driving structure, and save costs. The commodity transmission device 100 of this embodiment is particularly suitable for the transmission of soft-packaged commodities such as Chinese medicine beverage bags. Since the driving component 40 can directly or indirectly drive the first transmission component 10 and the second transmission component 30 to transmit, the soft-packaged commodities are subjected to a more balanced force during the transmission process, and there will be no slipping or jamming.

[0058] In one embodiment, the transmission assembly 20 includes a first mounting plate 21, a second mounting plate 22, a first hinge shaft 23, a first gear 24, a second gear 25 and a third gear 26; the first mounting plate 21 and the second mounting plate 22 are hingedly connected via the first hinge shaft 23, the first gear 24 is mounted on the first mounting plate 21, the second gear 25 is mounted on the second mounting plate 22, the third gear 26 is mounted on the first hinge shaft 23, and the first gear 24, the third gear 26 and the second gear 25 are meshed in sequence; the driving assembly 40 is respectively connected to the first gear 24 and the first transmission assembly 10, and the second gear 25 is connected to the second transmission assembly 30.

[0059] The first mounting plate 21 is used to mount the first gear 24, and the second mounting plate 22 is used to mount the second gear 25. The first mounting plate 21 and the second mounting plate 22 are respectively provided with first connection holes 212, and the first hinge shaft 23 is rotatably inserted in the two first connection holes 212, so that the first mounting plate 21 and the second mounting plate 22 can be relatively hinged and rotated. The first hinge shaft 23 is also used to mount the third gear 26, which can be hinged and rotated through the first hinge shaft 23. The first gear 24 and the second gear 25 are both meshed with the third gear 26. When the driving component 40 drives the first gear 24 to rotate, the first gear 24 drives the third gear 26 to rotate, and the third gear 26 drives the second gear 25 to rotate. While the driving component 40 directly drives the first transmission component 10 to transmit and operate, it can also drive the second transmission component 30 to transmit and operate through the first gear 24, the third gear 26, and the second gear 25. And because the first mounting plate 21 and the second mounting plate 22 can be hinged and rotated, the second transmission component 30 and the first transmission component 10 can move away from or closer to each other. Under the action of the elastic element 50, the second transmission component 30 can be pushed toward the first transmission component 10 without affecting the transmission of goods by the first transmission component 10 and the second transmission component 30.

[0060] The number of the first gear 24, the second gear 25 and the third gear 26 can be increased or decreased according to the required distance between the second transmission component 30 and the first transmission component 10, for example, the number of the first gear 24 and the second gear 25 can be one, two, etc. The total number of the first gear 24, the second gear 25 and the third gear 26 can also determine the transmission direction of the second transmission component 30. When the total number of the first gear 24, the second gear 25 and the third gear 26 is an odd number or an even number, the transmission direction of the second transmission component 30 is opposite. Therefore, the total number of the first gear 24, the second gear 25 and the third gear 26 can be set according to actual needs.

[0061] It is understandable that the transmission component 20 can also adopt other structures, as long as it can satisfy that the drive component 10 is connected to the second transmission component 30 through the transmission component 20, and the second transmission component 30 can move closer to / farther away from the first transmission component 10 when the transmission component 20 can be unfolded / folded. The examples are not listed here.

[0062] Please refer to Figure 6 and Figure 7 In one embodiment, the transmission assembly 20 also includes a fourth gear 27 and a first mounting shaft 28, and the fourth gear 27 and the first gear 24 are coaxially mounted on the first mounting shaft 28; the driving assembly 40 is connected to the first transmission assembly 10 through the fourth gear 27.

[0063] The first mounting shaft 28 is used to mount the first gear 24 and the fourth gear 27. When the driving assembly 40 is connected to the first mounting shaft 28 or the fourth gear 27, the first mounting shaft 28 can be driven to rotate. At this time, the fourth gear 27 drives the first transmission assembly 10 to transmit, and the first gear 24, the third gear 26 and the second gear 25 drive the second transmission assembly 30 to transmit. The first gear 24 and the fourth gear 27 are installed together on the first mounting shaft 28, and the first gear 24 and the fourth gear 27 can rotate synchronously. Therefore, the first transmission assembly 10 and the second transmission assembly 30 can also transmit synchronously, and the force acting on the goods is more balanced, which is conducive to the transmission of the goods. At the same time, it can also simplify the structure and save costs.

[0064] Please refer to Figures 6 to 8In one embodiment, the commodity transmission device 100 further includes a second mounting shaft 70 and two opposite third mounting plates 80; the third mounting plates 80 are respectively provided with strip grooves 82, and the strip grooves 82 on the two third mounting plates 80 are opposite; the second mounting shaft 70 is slidably mounted in the two opposite strip grooves 82, and the second transmission component 30 is mounted on the second mounting shaft 70. The two third mounting plates 80 are used to mount the second mounting shaft 70, and the second mounting shaft 70 can slide along the length direction of the two strip grooves 82. In some embodiments, when the transmission surface of the first transmission component 10 and the transmission surface of the second transmission component 30 are parallel to the horizontal plane, the two strip grooves 82 are arranged in the vertical direction, and the first transmission component 10 is located directly below the second transmission component 30. When the second mounting shaft 70 moves in the vertical direction, it can drive the second transmission component 30 to move in the vertical direction. Specifically, when there is no commodity being transmitted between the first transmission component 10 and the second transmission component 30, under the action of the elastic element 50, the first transmission component 10 and the second transmission component 30 are close to each other or even fit together. When the goods are squeezed in between the first transmission component 10 and the second transmission component 30, the second transmission component 30 moves upward in the vertical direction; when the goods between the first transmission component 10 and the second transmission component 30 are completely transmitted, the second transmission component 30 moves downward under the action of the elastic element 50 and returns to the initial position again.

[0065] The first transmission assembly 10 is generally fixed. It is understandable that the first transmission assembly 10 may also be movable, but it is necessary to consider the transmission coordination between the first transmission assembly 10 and the second transmission assembly 30. The third mounting plate 80 is mounted in the housing 101.

[0066] The strip groove 82 has a limiting effect on the second installation shaft 70, enabling the second installation shaft 70 and the second transmission component 30 to move up and down along a preset track, and ensuring that the second transmission component 30 moves up and down smoothly in the vertical direction to avoid deviating from the preset track.

[0067] It is understandable that, in some embodiments, the length direction of the strip groove 82 can also be set along other directions. At this time, the moving direction of the second transmission component 30 will also change, and the moving direction of the second transmission component 30 is the same as the length direction of the strip groove 82.

[0068] In one embodiment, the commodity transmission device 100 further includes a third installation shaft 60 and a hinge assembly 90; the third installation shaft 60 is fixed, one end of the hinge assembly 90 is hingedly connected to the second installation shaft 70, and the other end of the hinge assembly 90 is hingedly connected to the third installation shaft 60; the elastic element 50 includes a torsion spring, which is installed on the hinge assembly 90 to push the second transmission assembly 30 close to the first transmission assembly 10. The third installation shaft 60 is used to fix the hinge assembly 90. In a specific embodiment, the third installation shaft 60 is installed on two opposite third installation plates 80. The torsion spring acts on the hinge assembly 90 to push the second transmission assembly 30 close to the first transmission assembly 10. When the third installation shaft 60 is fixed, the hinge assembly 90 can adapt to the movement of the second installation shaft 70 along the length direction of the strip groove 82. It is ensured that the second transmission assembly 30 has a stroke along the length direction of the strip groove 82, and the distance between the first transmission assembly 10 and the second transmission assembly 30 can adapt to commodities of different thicknesses. The length of the strip groove 82 is the maximum moving stroke of the second transmission assembly 30. The torsion spring has a simple structure and can provide a continuous and stable elastic driving force.

[0069] It is understandable that the elastic element 50 can also be a tension spring or other structure with elastic force. For example, when the elastic element 50 is a spring, the spring can be stretched between the first transmission component 10 and the second transmission component 30 to make the first transmission component 10 and the second transmission component 30 close to each other.

[0070] Please refer to Fig. 9 In one embodiment, the hinge assembly 90 includes a first hinge block 91, a second hinge block 92 and a second hinge shaft 93, the first hinge block 91 and the second hinge block 92 are hingedly connected via the second hinge shaft 93, the torsion spring is installed on the second hinge shaft 93, one end of the torsion spring is pressed on the first hinge block 91, and the other end of the torsion spring is pressed on the second hinge block 92; one end of the first hinge block 91 away from the second hinge shaft 93 is hingedly connected to the second mounting shaft 70, and one end of the second hinge block 92 away from the second hinge shaft 93 is hingedly connected to the third mounting shaft 60.

[0071] The first hinge block 91 and the second hinge block 92 are respectively provided with a second connection hole 912 and a third connection hole 922. The second mounting shaft 70 and the third mounting shaft 60 are parallel. The second mounting shaft 70 and the third mounting shaft 60 are located above the second transmission assembly 30, and the two second connection holes 912 are also parallel. The second mounting shaft 70 is inserted in the second connection hole 912 of the first hinge block 91, and the third mounting shaft 60 is inserted in the second connection hole 912 of the second hinge block 92. The two ends of the torsion spring act on the first hinge block 91 and the second hinge block 92 respectively, pushing the first hinge block 91 and the second hinge block 92 to expand each other, thereby pushing the second transmission assembly 30 to move downward to approach the first transmission assembly 10. The second hinge shaft 93 is inserted in the two third connection holes 922, so that the first hinge block 91 and the second hinge block 92 can both rotate relative to the second hinge shaft 93.

[0072] In one embodiment, the hinge assembly 90 also includes a connecting plate 94, and the number of the first hinge blocks 91 and the number of the second hinge blocks 92 are two respectively; the first hinge blocks 91 are parallel to each other, and the second hinge blocks 92 are parallel to each other, and the first hinge blocks 91 are connected by one connecting plate 94, and the second hinge blocks 92 are connected by another connecting plate 94.

[0073] Multiple parallel first hinge blocks 91 can bear a larger load, and the connecting plate 94 can connect the first hinge blocks 91 to further improve the load bearing capacity of the first hinge blocks 91. Similarly, multiple parallel second hinge blocks 92 can also bear a larger load, and another connecting plate 94 can also connect multiple second hinge blocks 92 to further improve the load bearing capacity of the second hinge blocks 92. The number of the first hinge blocks 91 and the second hinge blocks 92 can be set according to actual needs, such as the number of the first hinge blocks 91 and the second hinge blocks 92 can be two, three or even more.

[0074] It can be understood that in some embodiments, the number of hinge assemblies 90 can be one, two or more. When the number of hinge assemblies 90 is two, the two hinge assemblies 90 are respectively located on both sides of the second transmission assembly 30, and the two hinge assemblies 90 can bear the gravity of the second transmission assembly 30 in a balanced manner.

[0075] Please refer to Figures 10 to 12In one embodiment, the first transmission component 10 includes a fifth gear 12, a sixth gear 14 and at least one first transmission roller 16, each of which is mounted with at least one fifth gear 12, and each of the first transmission rollers 16 is arranged side by side in sequence, and the fifth gears 12 of any two adjacent first transmission rollers 16 are meshed and transmitted through the sixth gear 14, and the drive component 40 is connected to at least one of the fifth gears 12 or at least one of the sixth gears 14 in transmission; the second transmission component 30 includes a seventh gear 32, an eighth gear 34 and at least one second transmission roller 36, each of which is mounted with at least one seventh gear 32, and each of the second transmission rollers 36 is arranged side by side in sequence, and the seventh gears 32 of any two adjacent second transmission rollers 36 are meshed and transmitted through the eighth gear 34, and the drive component 40 is also connected to at least one of the seventh gears 32 or at least one of the eighth gears 34 in transmission through the transmission component 20; the second transmission roller 36 and the first transmission roller 16 are parallel to each other, and the elastic element 50 is connected to the second transmission roller 36 in transmission to push the second transmission roller 36 to approach the first transmission roller 16.

[0076] The fifth gear 12 is used to directly drive the first transmission roller 16 to rotate. If any adjacent first transmission rollers 16 are directly meshed and driven by the fifth gear 12, the rotation directions of any two adjacent first transmission rollers 16 are opposite. In this embodiment, the sixth gear 14 is used to change the rotation direction of the first transmission roller 16 so that all the first transmission rollers 16 rotate in the same direction. Of course, multiple sixth gears 14 can be set between any two adjacent fifth gears 12, but the number of sixth gears 14 between any two adjacent fifth gears 12 should be an odd number to ensure that all first transmission rollers 16 rotate in the same direction. In the first transmission component 10, as long as the drive component 40 is indirectly or directly connected to at least one fifth gear 12 or at least one sixth gear 14, it can drive the first transmission rollers 16 to rotate synchronously. Among them, the second mounting shaft 70 and the second transmission roller 36 move synchronously in the vertical direction.

[0077] The seventh gear 32 is used to directly drive the second transmission rollers 36 to rotate. If any adjacent second transmission rollers 36 are directly meshed and driven by the seventh gear 32, the rotation directions of any two adjacent second transmission rollers 36 are opposite. In this embodiment, the eighth gear 34 is used to change the rotation direction of the second transmission rollers 36 so that all the second transmission rollers 36 rotate in the same direction. Of course, multiple eighth gears 34 can be set between any two adjacent seventh gears 32, but the number of eighth gears 34 between any two adjacent seventh gears 32 should be an odd number to ensure that the second transmission rollers 36 rotate in the same direction. In the second transmission component 30, as long as the driving component 40 is indirectly or directly connected to at least one seventh gear 32 or at least one eighth gear 34, it can drive the second transmission rollers 36 to rotate synchronously.

[0078] In one embodiment, the second transmission assembly 30 further includes a fourth mounting plate 38, and the seventh gear 32, the eighth gear 34 and the second transmission roller 36 are mounted on the fourth mounting plate 38; the elastic element 50 is connected to the fourth mounting plate 38 in a transmission manner to push the second transmission roller 36 close to the first transmission roller 16. The second mounting shaft 70 is connected to the fourth mounting plate 38, so that the second mounting shaft 70 is connected to the second transmission assembly 30, and when the second transmission assembly 30 moves up and down in the vertical direction, the second mounting shaft 70 can slide in the strip groove 82, which has a limiting effect on the movement of the second transmission assembly 30.

[0079] It can be understood that in some embodiments, the first transmission component 10 and the second transmission component 30 can also be a belt transmission mechanism, a rubber roller transmission mechanism, a roller transmission mechanism and a gear transmission mechanism, respectively. Users can choose according to actual needs, which will not be repeated here.

[0080] Please refer to Fig.13 and Fig.14 In some embodiments, the driving assembly 40 includes a motor 42 and a ninth gear 44. The ninth gear 44 is mounted on the output shaft of the motor 42. The ninth gear 44 is connected to the fourth gear 27 by transmission. The motor 42 drives the fourth gear 27 to rotate through the ninth gear 44, thereby driving the first gear 24 to rotate.

[0081] In some embodiments, the drive assembly 40 also includes a tenth gear 46, which is meshed and connected between the ninth gear 44 and the fourth gear 27. The number of the tenth gears 46 can be determined according to actual needs. By setting the tenth gear 46, a certain transmission ratio can be formed through the meshing of each tenth gear 46 and the fourth gear 27, which has the effect of reducing or increasing speed. At the same time, through the meshing of the tenth gear 46, the motor 42 can be installed in any spatial position, which is convenient for the installation of the motor 42 and other gears. Among them, the tenth gear 46 can be installed on the third mounting plate 80, so that the meshing transmission of the tenth gear 46 is more stable.

[0082] The driving assembly 40 also includes an eleventh gear 48 and a fifth mounting plate 49. The eleventh gear 48 is meshed and connected between the fourth gear 27 and the sixth gear 14. The number of the eleventh gear 48 can be determined according to actual needs. By providing the eleventh gear 48, a certain transmission ratio can be formed through the meshing of each eleventh gear 48 and the seventh gear 32, which has the effect of reducing or increasing speed. At the same time, through the meshing of the eleventh gear 48, the fourth gear 27 can be installed in any spatial position, which is convenient for the installation of the motor 42 and other gears.

[0083] Among them, each eleventh gear 48 can be installed on the fifth mounting plate 49, so that the meshing transmission of the eleventh gear 48 is more stable.

[0084] Each gear in this embodiment can be selected to adopt double gears or general gears according to needs. The installation of each gear in this embodiment refers to a rotatable installation, that is, each gear is required to be able to rotate in order to achieve meshing transmission.

[0085] The motor 42 in this embodiment can be controlled by a control circuit, a single chip microcomputer or an integrated circuit, etc., and has a simple structure and is easy to operate.
