1. Technical Field
The present disclosure relates to automatic vending machines, particularly to an automatic vending machine with a buffering device.
2. Description of Related Art
Automatic vending machines allow customers to buy products at any hours of the day. When the customer purchases the product from the automatic vending machine, a helical element in a cabinet is rotated to push the product out of the cabinet. However, a free end of the helical element may be warped or otherwise act to snag or catch on the product, preventing the delivery of the product out of the cabinet. In addition, the pressure between the product and the cabinet may be so high that the product may be destroyed. Therefore, there is room for improvement within the art.
Many aspects of the embodiments can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the embodiments. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings in which like references indicate similar elements. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean “at least one.”
The cabinet 10 comprises a bottom plate 11, a top plate 12, and two side plates 13 connected to the bottom plate 11 and the top plate 12. In one embodiment, the top plate 12 is substantially parallel to the bottom plate 11. The bottom plate 11 comprises a guiding surface 14 for product. In one embodiment, the guiding surface 14 is slanted.
Each transporting device 20 comprises a bottom panel 21, a top panel 23, two side panels 25, and a separating panel 26 located between the two side panels 25. In one embodiment, the top panel 23 is substantially parallel to the bottom panel 21 and perpendicular to the side panels 25. The separating panel 26 is substantially parallel to each side panel 25, so that a first passageway 281 and a second passageway 282 are defined by the separating panel 26 and the two side panels 25. The bottom panel 21 defines an opening 211. A guiding panel 27 extends from a first one of the two side panels 25 and is located above the opening 211. A slot 250 is defined in a second one of the two side panels 25. In one embodiment, the guiding panel 27 is substantially perpendicular to the side panel 25 and parallel to the bottom panel 21. The guiding panel 27 comprises a slanted surface 271 located below the first passageway 281. In one embodiment, a gap 29 is defined between the separating panel 26 and the guiding panel 27, for products extending therethrough. A positioning post 22 protrudes from the top panel 23.
Each driving device 30 is secured to each transporting device 20 and comprises a driving member 31 and a pushing member 32 secured to the driving member 31. The pushing member 32 can be rotated by the driving member 31. In one embodiment, the pushing member 32 is substantially L-shaped.
Each buffering device 40 comprises a hollow box 42 and a supporting panel 41 extending from the hollow box 42. The hollow box 42 comprises opposite first side panels 44 and opposite second side panels 45. In one embodiment, each first side panel 44 is substantially perpendicular to each second side panel 45. The hollow box 42 comprises an entrance 46 and an exit 47 opposite to the entrance 46. In one embodiment, a size of the entrance 46 is substantially equal to a size of the exit 47, and also equal to a size of the opening 211. The supporting panel 43 is substantially perpendicular to the first side panel 44, and a receiving slot 43 is defined in the supporting panel 41.
In use, a first product drops into the first passageway 281, extends through the first passageway 281 and drops into the hollow box 42. A second product drops into the second passageway 282, extends through the second passageway 282 and the slanted surface 271, and drops into the hollow box 42. Then, the driving member 30 works and the pushing member 32 is rotated and slid in the receiving slot 43. Thus, the buffering device 40 with the first and second merchandise is moved in a direction that is substantially parallel to the bottom panel 21 by the pushing member 32. Until the exit 47 is aligned with the opening 211, the first and second product moves out of the transporting device 20 via the opening 211. At this time, the buffering device 40 is located in a second position, the hollow box 42 is located below the guiding panel 27, and the supporting panel 41 is located below the first passageway 281 and aligned with the guiding panel 27.
After the first and second products move out of the transporting device 20, the driving member 30 works and the pushing member 32 is rotated and slid in the receiving slot 43 to remove the buffering device 40 back to the first position, to wait for receiving the next product.
It is to be understood, however, that even though numerous characteristics and advantages have been set forth in the foregoing description of embodiments, together with details of the structures and functions of the embodiments, the disclosure is illustrative only and changes may be made in detail, especially in the matters of shape, size, and arrangement of parts within the principles of the disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
