The invention has the benefit that this programme is used for Self-help vending machine picking, after user buys successfully, motor is driven
Left leather belt wheel and the rotation of right leather belt wheel, and then slide belt band movable slider on the slide rail, and pulley rolls in sliding slot, takes
Goods slot reaches at the shelf of bought cargo, catches the commodity slid from shelf, then picking slot is displaced downwardly to vending machine again
Access section at;It is driven by belt, structure is simple, and cost is small, and sliding block is slided in sliding slot by pulley, reduces
Friction between sliding block and sliding rail, noise is small, stable transmission.
It is provided with the convex closure with pulley cooperation in groove, reduces the shaking of pulley during scrolling, keeps movement more flat
Surely;Picking slot is hinged on link block, after the success of picking slot picking, when picking slot is moved down at the access section of vending machine, is taken
The side of goods slot is withstood by bar, so that picking slot, towards one side to overturn of access section or inclination, user's picking is more easier;"U"
The design of the fastener and limiting section of shape can further increase stability of the sliding block in sliding process, and infrared sensor is for examining
Whether have cargo, it is ensured that picking success if measuring in goods slot.

Specific embodiment
A specific embodiment of the invention is described below, in order to facilitate understanding by those skilled in the art this hair
It is bright, it should be apparent that the present invention is not limited to the ranges of specific embodiment, for those skilled in the art,
As long as various change is in the spirit and scope of the present invention that the attached claims limit and determine, these variations are aobvious and easy
See, all are using the innovation and creation of present inventive concept in the column of protection.
As depicted in figs. 1 and 2, the vertical lift picking mechanism of vending machine includes two sliding rails being vertically arranged 5, two cunnings
Rail 5 is each attached on the shell of vending machine, is provided with picking slot 8 between two one slide rails 5;Sliding slot is offered on two one slide rails 5
12, it opens up on the side wall of sliding slot 12 fluted, is rolled in groove and be provided with pulley 19;Pulley 19 is mounted in fixing axle 14, Gu
Dead axle 14 is fixedly connected with sliding block 15, is provided with gap between sliding block 15 and sliding rail 5, it is ensured that can phase between sliding block 15 and sliding rail 5
To sliding, the both ends of picking slot 8 are fixed on sliding block 15.
It is provided with two left leather belt wheels 2 of the connection of belt 16 positioned at the upper and lower end of the sliding rail 5 in left side, is located at right side
The upper and lower end of sliding rail 5 be provided with two right leather belt wheels 4 of the connection of belt 16, sliding block 15 is fixed on belt 16, passes through
Belt 16, which drives, realizes upper and lower sliding;Left leather belt wheel 2 and right leather belt wheel 4 in 5 upper end of sliding rail are connected by shaft 3, in sliding rail
