Abstract

The present invention relates to pneumatic ball backing accelerator in bowling equipment, relates to culture and sports equipment, and aims at simplifying structure, raising running reliability and raising ball backing speed. The pneumatic ball backing accelerator has one accelerating arm capable of rotating around the rotation shaft on the positioning frame, cylinder hinged to the accelerating arm and with end link rod hinged via the rotation shaft to the positioning frame and starting switch in the ball backing line, and corresponding pneumatically controlling and electrically controlling system. After ball falls into the ball backing path, the accelerating arm can hit the ball in the back violently to speed ball backing. The present invention can raise the ball backing speed greatly.

Description

Pneumatic returned ball accelerator in the bowling equipment

Technical field

The invention belongs to culture, sports goods field, relate to the pneumatic returning accelerator in a kind of bowling equipment.

Background technology

In the prior art, the return of serve speed of bowling (hereinafter to be referred as ball) was generally 10～14 seconds, returning unit has two classes basically, one class such as the disclosed scheme of Chinese patent ZL972313478, its transmission mechanism be, earlier ball is promoted certain altitude or the extruding speedup of holding concurrently after ball rely on self potential energy and kinetic energy to return along return automatically, its complex structure, cost height, easy break-down, noise is big, and return of serve speed is difficult to improve; Another kind of as the disclosed scheme of Chinese patent ZL012298115, to traditional new technological break-through arranged, has outstanding advantage, need not ball is promoted certain altitude, both need not to improve the potential energy of ball, its transmission mechanism just carries out monistic squash type to preacceleration by driving-belt to ball, device independence is strong, adjustability is strong, easily installation and maintenance, weak point are that structure is still complicated, and return of serve speed improves little.Common disadvantage of the prior art is after the start, no matter have or not return of serve, and its transmission mechanism turns round all the time and do not stop, and therefore power consumption is high, and noise is continuous.

The technical scheme that adopts:

Pneumatic returning accelerator in the bowling equipment, it is characterized in that: have acceleration arm 1, this acceleration arm can install around first rotating shaft, 2 rotations on locating rack 8, below first rotating shaft 2, acceleration arm 1 is hinged with the piston rod 5 of cylinder 4 by second rotating shaft 3, and the seat end link 6 of cylinder 4 is hinged with locating rack 8 by the 3rd rotating shaft 7, and locating rack 8 is an independent rack 10, being contained on the relevant position of the detachable property of this frame, perhaps locating rack 8 is corresponding wallboard 24; Other has the starting switch 9 of cylinder 4, and this switch is a light-operated switch, perhaps is contact-making switch, and this switch is contained in ball 11 and rolls out on the route that goal mouth 12 falls into return 13; Corresponding structure, component locations and installation, must guarantee, ball 11 rolls out the process that goal mouth 12 falls into return 13, can block the optical signal of light-operated switch, perhaps can trigger contact-making switch, thereby starting switch 9 is started, and and then start cylinder 4 automatically, when ball 11 falls on the return 13 and rolls forward, cylinder 4 after the startup is outwards upheld promotion acceleration arm 1 by piston rod 5 and is rotated suddenly clockwise, jerk forward immediately 11 back of the corresponding site of the lower end left surface by acceleration arm 1 quickens return of serve, and then acceleration arm 1 self-return is static; The normal open switch K that is controlled by starting switch 9 that also has power supply V, and corresponding gas control, electric-control system.

Beneficial effect:

Simple in structure, easily make, cost is low, is convenient to install, regulates, safeguards that return of serve speed obviously improves, and can reach for 6～8 seconds that reliable, the life-span is long, and energy-conservation; Even if having bottle to go out goal mouth 27 once in a while, also do not influence normal return of serve.

The specific embodiment

Further explanation in detail in conjunction with the accompanying drawings;

23 are shown goal-board among the figure, and 24 are shown wallboard.

As shown in figs. 1 and 3, locating rack 8 is an independent rack 10, being contained on the relevant position of the detachable property of this frame, and perhaps locating rack 8 is corresponding wallboard 24; Starting switch 9 is a light-operated switch, and promptly ball 11 process that falls into return 13 can be blocked the optical signal of light-operated switch, thereby makes the normal open switch K of interlocking closed and connect power supply, starts cylinder 4; Perhaps be contact-making switch, promptly ball 11 process that falls into return 13 can trigger contact-making switch, thereby makes the normal open switch K of interlocking closed and connect power supply, starts cylinder 4; Normal open switch K is that on-delay is adjustable, could the automatic disconnection return after promptly closed connection and the time-delay.

As shown in Figure 2, gas control, electrical control system structure are as follows: the compressed gas of source of the gas D through the first defeated Han this 21 and valve 22 send into switch valve with two-position and five-pass 20, divide two-way then, one the tunnel through the 3rd appendix 17 and seat end gas port 15 input cylinders 4, one the tunnel through second appendix 16 and rod end gas port 14 input cylinders 4, and the first noise elimination air bleeding valve 19 and second air bleeding valve 18 of cooling down is housed respectively on two corresponding return-air interfaces on the switch valve with two-position and five-pass 20; The normal open switch K of power supply V connects switch valve with two-position and five-pass 20, and is controlled by starting switch 9, i.e. normal open switch K and starting switch 9 interlockings; Cylinder 4 is the common cylinder of QGA, QGB series, and switch valve with two-position and five-pass 20 is a SVF series, is Shanghai three subsidiary factories of pneumatic complete company and produces; The gas pressure of source of the gas D is generally 6～8kg/cm ²

Operation principle and using method:

Generally speaking, goal-board 23 is in closes shape, normal open switch K is in off-state, switch valve with two-position and five-pass 20 is in the deenergization shape, then compressed gas is sent into switch valve with two-position and five-pass 20 through first appendix 21 and valve 22, and enter cylinder 4 through second appendix 16, rod end gas port 14, and promotion piston rod 5 retractions, thereby pulling acceleration arm 1 rotates counterclockwise stall around main shaft 2, return-air enters switch valve with two-position and five-pass 20 through seat end gas port 15 and the 3rd appendix 17, and by 19 emptying of the first noise elimination air bleeding valve; Roll out the process that goal mouth 12 falls into return 13 at ball 11, starting switch 9 is started, thereby the closed and time-delay of the normal open switch K that makes interlocking, switch valve with two-position and five-pass 20 is in connects the power supply shape, after then compressed gas is sent into this valve commutation, through the 3rd appendix 17, seat end gas port 15 enters cylinder 4, and promotion piston rod 5 is outwards upheld, thereby promoting acceleration arm 1 rotates suddenly clockwise, jerk forward immediately 11 back of corresponding site by its lower end left surface, quicken return of serve, return-air is through rod end gas port 14, second appendix 16 enters switch valve with two-position and five-pass 20, and by 18 emptying of the second noise elimination air bleeding valve, normal open switch K closure reaches time-delay back automatic disconnection return, thereby make switch valve with two-position and five-pass 20 from newly being in the deenergization shape, therefore the meeting self-return was static after acceleration arm 1 quickened to return serve and finishes, and treated to go out ball next time, ran so forth; During adjacent two alley interlockings, the ball 11 of certain alley rolls out goal mouth 12 when being quickened by return of serve, and the ball 11 of another alley does not go out goal mouth 12; In the normal open switch K closure state process, do not influence normally in time closing of corresponding goal-board 23 and put in place.
