Embodiment
The technical solution of the utility model is further illustrated by embodiment below in conjunction with accompanying drawing.
Fig. 1 is the schematic diagram of the return of goods mechanism of a kind of vending machine of the utility model, comprise casing 1, the both sides of casing 1 are provided with infrared light transducer[sensor 2, the angle of casing 1 base plate and surface level is between 10 °-50 °, the top of casing 1 is provided with motor 3 and tooth bar 4, and described motor 3 is connected by gear 6 with tooth bar 4.Motor 3 is arranged on motor cabinet 5, ensures that motor 3 reliably can carry out work by normal table.The top of casing 1 is provided with back up pad 7, is provided with slide rail 8 bottom back up pad 7, and described slide rail 8 is the one in ball guide or roller slide rail.Back up pad 7 is provided with primary importance sensor 9 and second place sensor 10, described primary importance sensor 9 is in before second place sensor 10.The right side of back up pad 7 is provided with baffle plate 11, and described baffle plate 11 is 90 ° with the angle of surface level.The rear side of casing 1 is provided with door-plate 12, and described door-plate 12 is connected by door-hinge 13 with casing 1, and the two ends of door-hinge 13 are separately fixed at the galianconism end of bell crank 14, the long arm end of bell crank 14 are provided with pulley 15, and described pulley 15 contacts with back up pad 7.
The angle of casing 1 base plate and surface level is between 10 °-50 °, namely base plate to the tilted angle of casing 1 between 10 °-50 °, for different article, select the angle of inclination also different, the commodity do not got in vending machine shipment platform casing and the article of failing to understand can be facilitated like this to reclaim along the free landing of the gradient, and without the need to additionally energizing.
The top of casing 1 is provided with motor 3 and tooth bar 4, and motor 3 is connected by gear 6 with tooth bar 4, and motor 3 rotates, and by gear 6 and tooth bar 4, energy is passed to casing 1, thus casing 1 can be done along slide rail 8 move 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 there are the commodity or foreign material do not got.When having the commodity do not got or foreign material to exist in vending machine shipment platform casing 1, the commodity do not got or foreign material can stop the infrared light that infrared light transducer[sensor 2 emits, now infrared light transducer[sensor 2 will judge to have in casing 1 commodity do not got or foreign material to exist, and return of goods mechanism will return goods or removal treatment to the commodity do not got or foreign material; When there are not the commodity or foreign material do not got in vending machine shipment platform casing 1, the infrared light that infrared light transducer[sensor 2 emits can directly by vending machine shipment platform casing 1, now infrared light transducer[sensor 2 will judge not exist in casing 1 commodity or foreign material do not got, then return goods or removal treatment without the need to carrying out.
Back up pad 7 is provided with primary importance sensor 9 and second place sensor 10, wherein primary importance sensor 9 is in before second place sensor 10, when infrared light transducer[sensor 2 does not detect in casing 1 commodity or foreign material that have and do not get, motor 3 rotates, and by gear 6 and tooth bar 4, energy is passed to casing 1, make casing 1 move to primary importance sensor 9 along slide rail 8 and namely stop; When infrared light transducer[sensor 2 detects in casing 1 commodity that have and do not get or foreign material exist, motor 3 rotates, and by gear 6 and tooth bar 4, energy is passed to casing 1, casing 1 is made to move to second place sensor 10 along slide rail 8, now door-plate 12 is opened, the commodity do not got or foreign material landing, thus complete the return of goods or removal treatment.After the return of goods or removal treatment complete, when infrared light transducer[sensor 2 detects in casing 1 commodity or foreign material that have not existed and do not got, motor 3 rotates backward, and by gear 6 and tooth bar 4, energy is passed to casing 1, casing 1 is moved to primary importance sensor 9 along slide rail 8 from second place sensor 10, when casing 1 moves to primary importance sensor 9, door-plate 12 cuts out.
During utility model works, when infrared light transducer[sensor 2 does not detect in casing 1 commodity or foreign material that have and do not get, motor 3 rotates, and by gear 6 and tooth bar 4, energy is passed to casing 1, casing 1 is moved along slide rail 8 backward, pulley 15 also can roll along back up pad 7 backward, owing to returning goods or removal treatment without the need to carrying out, stop when casing 1 moves to primary importance sensor 9 moving backward, now pulley 15 moves to the position contacted with baffle plate 11 just, and door-plate 12 is cut out, when infrared light transducer[sensor 2 detects in casing 1 commodity that have and do not get or foreign material exist, motor 3 rotates, and by gear 6 and tooth bar 4, energy is passed to casing 1, make casing 1 in the process of moving to primary importance sensor 9 along slide rail 8, because casing 1 base plate has certain degree of tilt, the commodity do not got in casing 1 or foreign material can drop down onto along base plate free skating the position contacted with door-plate 12, pulley 15 also can roll along back up pad 7 backward, when casing 1 moves to primary importance sensor 9, pulley 15 moves to the position contacted with baffle plate 11 just, now door-plate 12 is cut out, the commodity do not got or foreign material cannot drop, motor 3 is rotated further, and by gear 6 and tooth bar 4, energy is passed to casing 1, casing 1 is made to continue to move to second place sensor 10 along slide rail 8 from primary importance sensor 9, pulley 15 up can move along baffle plate 11, bell crank 14 is rotated up around door-hinge 13, thus drive door-plate 12 Unscrew, when casing 1 moves to second place sensor 10, door-plate 12 is also opened to certain degree, the commodity do not got or foreign material can drop, thus complete the return of goods or removal treatment.After the return of goods or removal treatment complete, infrared light transducer[sensor 2 detects in casing 1 commodity or foreign material that have not existed and do not got, motor 3 rotates backward, and by gear 6 and tooth bar 4, energy is passed to casing 1, casing 1 is moved to primary importance sensor 9 along slide rail 8 from second place sensor 10, pulley 15 down can move along baffle plate 11, bell crank 14 is rotated down around door-hinge 13, thus drive door-plate 12 rotary closing, when casing 1 moves to primary importance sensor 9 along slide rail 8, pulley 15 down moves to the position contacted with baffle plate 11 just, now door-plate 12 cuts out.
The utility model possesses returns goods and clean function automatically, handling return can be carried out the commodity do not got in vending machine shipment platform casing and Automatic clearance is carried out to not clear article, thus effectively ensure that the normal table work of vending machine, improve the comfort of user's shopping.
Embodiment recited above is only be described preferred implementation of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that the common engineering technical personnel in this area make the technical solution of the utility model and improvement, all should fall in protection domain that claims of the present utility model determine.
