Specific embodiment
Further illustrate technical scheme below in conjunction with the accompanying drawings and by specific embodiment.
Fig. 1 is a kind of schematic diagram of the return of goods mechanism of vending machine of the invention, including casing 1, and the both sides of casing 1 are set
There is an infrared light transducer[sensor 2, between 10 ° -50 °, the top of casing 1 is provided with the He of motor 3 to the angle of the base plate of casing 1 and horizontal plane
Tooth bar 4, the motor 3 and tooth bar 4 are connected by gear 6.Motor 3 is arranged on motor cabinet 5, it is ensured that motor 3 can be normal
Reliablely and stablely it is operated.The top of casing 1 is provided with supporting plate 7, and the bottom of supporting plate 7 is provided with slide rail 8, the slide rail 8
It is the one kind in ball guide or roller slide rail.First position sensor 9 and second place sensor are provided with supporting plate 7
10, the first position sensor 9 is in before second place sensor 10.The right side of supporting plate 7 is provided with baffle plate 11, institute
The angle that baffle plate 11 is stated with horizontal plane is 90 °.The rear side of casing 1 is provided with door-plate 12, and the door-plate 12 passes through door-hinge with casing 1
13 are connected, and the two ends of door-hinge 13 are separately fixed at the galianconism end of bell crank lever 14, are provided with the long arm end of bell crank lever 14
Pulley 15, the pulley 15 is in contact with supporting plate 7.
The angle of the base plate of casing 1 and horizontal plane is between 10 ° -50 °, that is, base plate exists to the tilted angle of casing 1
Between 10 ° -50 °, for different articles, select inclined angle also different, can so facilitate vending machine shipment
The commodity and not clear article not taken in platform container body freely slide and reclaim along the gradient, and without additionally energizing.
The top of casing 1 is provided with motor 3 and tooth bar 4, and motor 3 is connected with tooth bar 4 by gear 6, and motor 3 is rotated,
And energy is transmitted to by casing 1 by gear 6 and tooth bar 4, so that casing 1 can do along slide rail 8 moving accordingly.
The both sides of casing 1 are provided with infrared light transducer[sensor 2, can detect in vending machine shipment platform casing 1 whether
In the presence of the commodity or debris that do not take.In the presence of having the commodity or debris not taken in vending machine shipment platform casing 1,
The commodity or debris not taken can stop the infrared light that infrared light transducer[sensor 2 is emitted, and now infrared light transducer[sensor 2 will be sentenced
Break and in casing 1 with the presence of the commodity or debris not taken, return of goods mechanism will return goods to the commodity or debris that do not take
Or prune job;When in vending machine shipment platform casing 1 in the absence of the commodity or debris not taken, infrared light sensing
The infrared light that device 2 is emitted can directly pass through vending machine shipment platform casing 1, and now infrared light transducer[sensor 2 will
Judge in casing 1 in the absence of the commodity or debris not taken, then need not be returned goods or prune job.
First position sensor 9 and second place sensor 10, wherein first position sensor 9 are provided with supporting plate 7
Before second place sensor 10, when infrared light transducer[sensor 2 does not detect the commodity or miscellaneous for having in casing 1 and not taking
In the presence of thing, motor 3 is rotated, and energy is transmitted into casing 1 by gear 6 and tooth bar 4 so that casing 1 is moved to along slide rail 8
First position sensor 9 stops;In the presence of infrared light transducer[sensor 2 is detected and has the commodity or debris not taken in casing 1,
Motor 3 is rotated, and energy is transmitted into casing 1 by gear 6 and tooth bar 4 so that casing 1 moves to the second place along slide rail 8
Sensor 10, now door-plate 12 open, the commodity or debris that do not take slide, so as to complete to return goods or prune job.Return goods
Or after the completion of prune job, infrared light transducer[sensor 2 is detected when not existed the commodity or debris that do not take in casing 1, electricity
Machine 3 is rotated backward, and energy is transmitted into casing 1 by gear 6 and tooth bar 4 so that casing 1 is passed along slide rail 8 from the second place
Sensor 10 is moved to first position sensor 9, and when casing 1 moves to first position sensor 9, door-plate 12 is closed.
During present invention work, when infrared light transducer[sensor 2 is not detected in casing 1 with the presence of the commodity or debris not taken
When, motor 3 is rotated, and energy is transmitted into casing 1 by gear 6 and tooth bar 4 so that casing 1 is moved backward along slide rail 8, sliding
Wheel 15 also can backward be rolled along supporting plate 7, due to that need not be returned goods or prune job, when casing 1 moves to first
Stop moving backward when putting sensor 9, now pulley 15 moves to the position being in contact with baffle plate 11 just, door-plate 12 is to close
Close;In the presence of infrared light transducer[sensor 2 is detected and has the commodity or debris not taken in casing 1, motor 3 is rotated, and is passed through
Energy is transmitted to casing 1 by gear 6 and tooth bar 4 so that casing 1 is in the process moved to first position sensor 9 along slide rail 8
In, because the base plate of casing 1 has certain gradient, the interior commodity not taken of casing 1 or debris can be dropped down onto along base plate free skating
The position being in contact with door-plate 12, pulley 15 also can backward be rolled along supporting plate 7, when casing 1 moves to first position sensing
During device 9, pulley 15 moves to the position being in contact with baffle plate 11 just, and now door-plate 12 is to close, the commodity that do not take or
Debris cannot be dropped, and motor 3 is rotated further, and energy is transmitted into casing 1 by gear 6 and tooth bar 4 so that casing 1 continues edge
Slide rail 8 to be moved to second place sensor 10 from first position sensor 9, pulley 15 can up be moved along baffle plate 11, be made
Obtain bell crank lever 14 to be rotated up around door-hinge 13, so as to drive the Unscrew of door-plate 12, passed when casing 1 moves to the second place
During sensor 10, door-plate 12 is also opened to certain degree, is dropped by the commodity or debris that do not take, thus complete return goods or
Prune job.After the completion of the return of goods or prune job, infrared light transducer[sensor 2 is detected in casing 1 has not existed the commodity not taken
Or debris, motor 3 is rotated backward, and energy is transmitted into casing 1 by gear 6 and tooth bar 4 so that casing 1 along slide rail 8 from
Second place sensor 10 is moved to first position sensor 9, and pulley 15 can down be moved along baffle plate 11 so that bell crank lever
14 are rotated down around door-hinge 13, so as to drive the rotary closing of door-plate 12, are passed when casing 1 moves to first position along slide rail 8
During sensor 9, pulley 15 down moves to the position being in contact with baffle plate 11 just, and now door-plate 12 is closed.
The present invention possess it is automatic return goods and cleaning function, can be to the business that is not taken in vending machine shipment platform container body
Product carry out handling return and the article to failing to understand is cleared up automatically, so as to be effectively guaranteed the normal table of vending machine
Work, improves the comfort of user's shopping.
Embodiment described above is only that the preferred embodiment of the present invention is described, not to model of the invention
Enclose and be defined, on the premise of design spirit of the present invention is not departed from, this area ordinary skill technical staff is to skill of the invention
Various modifications and improvement that art scheme is made, all should fall into the protection domain of claims of the present invention determination.
