The mechanism that draws a bill of automatic machine
Technical field:
The utility model relates to a kind of automatic ticket-selling system that is applied in the track traffic, especially a kind of mechanism that draws a bill of automatic machine.
Background technology:
At present automatic machine ticket distributing device is mainly by ticket card unloading device, ticket card transport sector, and ticket card read-write equipment, ticket card part flow arrangement is formed.In these links, the reliability of ticket card unloading device and response time directly influence this flow process of ticketing.There is following problem in the existing mechanism that draws a bill:
1. it is highly inaccurate between wheel and ticket card to get tickets, friction force between influence wheel and ticket card.
2. friction force is too small can't normally take out the ticket card.
3. friction force is crossed senior general and is caused many cards to be removed simultaneously, causes ticket card read-write failure.
4. ticket card read-write failure need be got tickets again, has prolonged individual and has got tickets the time.
5. the ticket card can't normally take out, and has a strong impact on the operate as normal of whole ticket sale system.
Summary of the invention:
In order to solve the above-mentioned deficiency of prior art, the utility model provides a kind of card taking effective, uses reliably, and the life-span is long, and the response time is fast, the mechanism that draws a bill of automatic machine easy to maintenance.
Technical solution of the present utility model is as follows: a kind of mechanism that draws a bill of automatic machine, be provided with riser, on riser one side, be fixed with stepper motor, driving wheel on the stepper motor is connected with first power wheel by first travelling belt, first power wheel is connected with second power wheel by second travelling belt, second power wheel is connected with engaged wheel by the 3rd travelling belt, is provided with expansion tightening wheel in a side of first travelling belt; On the opposite side of riser, be provided with the wheel of getting tickets that is provided with the coaxial I of engaged wheel, ticket delivering wheel with the coaxial II setting of second power wheel, and the holder ticket wheel that is provided with the coaxial III of first power wheel, the axle I by Bearing Installation on the wheel support of getting tickets, the wheel support of getting tickets is connected with spring column on being fixed on riser by regulating spring, axle II is fixed on the riser by bearing seat, axle III is holding in the palm on the ticket wheel support by Bearing Installation, holder ticket wheel support is installed on the riser lotting baffle plate that also is provided with on the fixed mount by fixed mount.
Described lotting baffle plate is arranged on the below of ticket delivering wheel.
Described holder ticket wheel is loose pulley.
Outstanding feature of the present utility model is that the get tickets position of wheel can be regulated by the regulating spring on its support, and then can adjust the friction force between get tickets wheel and ticket card, can take out smoothly with assurance ticket card.Height between ticket delivering wheel and the holder ticket wheel can be regulated by holder ticket wheel fixed mount in addition, simultaneously by adjusting expansion tightening wheel to guarantee the tensioner degree of first travelling belt.The lotting baffle plate can stick into the row adjusting according to the ticket of different-thickness in addition, guarantees to have only single-ticket cartoon mistake, can not pass through more than two.Ticket is stuck in and is keeping good clamping transmission between the wheel of getting tickets, ticket delivering wheel and the holder ticket wheel, and the ticket card does not have bending, and the take-off time of single-ticket card only is 0.2S, reduces the time of getting tickets greatly, guarantees that the ticket distributing overall process is reliable, efficient.

Embodiment:
Further specify specific embodiment of the utility model below in conjunction with accompanying drawing:
Shown in Fig. 1~4, a kind of mechanism that draws a bill of automatic machine, be provided with riser, on riser one side, be fixed with stepper motor 19, driving wheel 18 on the stepper motor 19 is connected with first power wheel 15 by first travelling belt 17, first power wheel 15 is connected with second power wheel 7 by second travelling belt 16, and second power wheel 7 passes through the 3rd travelling belt 8 and is connected with engaged wheel 9, is provided with expansion tightening wheel 20 in a side of first travelling belt 17; On the opposite side of riser, be provided with the wheel 1 of getting tickets that is provided with the coaxial I2 of engaged wheel 9, the ticket delivering wheel 4 that is provided with second power wheel, 7 coaxial II3, and the holder ticket wheel 10 that is provided with first power wheel, 15 coaxial III11, holder ticket wheel 10 is a loose pulley.The axle I2 by Bearing Installation on the wheel support 5 of getting tickets, the wheel support 5 of getting tickets is connected with spring column 22 on being fixed on riser by regulating spring 21, axle II3 is fixed on the riser by bearing seat 6, axle III11 is holding in the palm on the ticket wheel support 12 by Bearing Installation, holder ticket wheel support 12 is installed on the riser lotting baffle plate 14 that also is provided with on the fixed mount 13 by fixed mount 13.Described lotting baffle plate 14 is arranged on the below of ticket delivering wheel 4.
The course of work is as follows:
The pawn ticket cartoon is crossed lifting gear and is contacted with the wheel of getting tickets, and when arriving the fixed position, sensor sends signal and stops to promote action.After receiving the instruction of getting tickets, stepper motor 19 rotates, and drive holder ticket wheel shaft III11 for first power wheel, 15, the first power wheels 15 transmission of power by first travelling belt 17 and rotate, but holder ticket wheel 10 does not rotate with axle III11, self free-runing operation.First power wheel 15 is given second power wheel 7 with transmission of power again with crossing second travelling belt 16, second power wheel 7 drives ticket delivering wheel transmission shaft II3 and rotates, axle II3 will drive ticket delivering wheel 4 and rotatablely move, second power wheel 7 finally outputs power to engaged wheel 9 by the 3rd travelling belt 8, engaged wheel 9 drives the wheel shaft I2 that gets tickets and rotates, and axle I2 drives the wheel 1 of getting tickets and rotates.Under wheel 1 the rotation of getting tickets drives, the ticket card braces box of drawing a bill.Then ticket delivering wheel 4 is taken turns 10 transmission once more with the holder ticket, is sent to the ticket card read-write zone of next stage.
