Description

Dry Chemical Extinguisher Screwing Device

Technical field

The utility model belongs to the filling machine technical field, relates in particular to a kind of Dry Chemical Extinguisher Screwing Device.

Background technology

When producing dry powder extinguisher, after powder filling in the dry powder extinguisher tank body, the gas head should be installed and screw.Current installation, screw the gas head and adopt manual type mostly, this mode effort of not only taking a lot of work, and the degree that screws is by people's sensation, and degree of tightness is very inaccurate.

The utility model content

Problem to be solved in the utility model just provides and a kind ofly need not manually screw gas head, degree of tightness Dry Chemical Extinguisher Screwing Device accurately.

For addressing the above problem, the technical solution adopted in the utility model is: comprise several delivery rolls, described delivery roll is provided with the pallet that holds the dry powder extinguisher tank body, tank body has the gas head, be provided with the stubborn hand of band ultrasonic sensor above the delivery roll, photoelectric sensing locator and torque sensor, twisting hand is connected with motor by reductor with torque sensor, twist between hand and the delivery roll and be provided with left and right sides tong, delivery roll with stubborn hand position matching part be provided with before and after interception post, front and back proximity transducer and push rod, ultrasonic sensor, twist hand, the photoelectric sensing locator, torque sensor, reductor, motor, left and right sides tong, the front and back interception post, the front and back proximity transducer is connected with controller respectively with push rod.

Its additional technical feature is: described stubborn hand is connected with lifting motor; The bottom surface of described pallet rear and front end has groove, and the position of the position of pallet groove and front and back interception post is complementary.

Dry Chemical Extinguisher Screwing Device provided by the utility model compared with prior art, be provided with delivery roll and stubborn hand, when tank body runs to interception post place, back with previous pallet on delivery roll, back interception post stops previous pallet, the back proximity transducer is transported to controller with signal simultaneously, after via controller confirms that the main attack position does not have pallet, controller sends signal, back interception post falls, previous pallet advances to the main attack position and is stopped by preceding interception post, simultaneously, back interception post can stop a back pallet, to avoid influencing the tank body powder filling on the previous pallet.After previous pallet is stopped by preceding interception post, preceding proximity transducer is transported to controller with signal, controller sends signal, push rod under cylinder action with previous pallet jack-up, left and right sides tong clamps tank body, ultrasonic sensor makes stubborn hand turn to the gas head equidirectional by controller, stubborn then subordinate falls and blocks the gas head, then under the effect of motor and speed reducer, stubborn hand begins to drive the rotation of gas head, this moment, tank body was clamped motionless, after waiting to reach predetermined torque, torque sensor sends signal to controller, and controller sends instruction, left tong, right tong unclamps, tank body is gentle first with rotation with stubborn hand, after treating that the gas head arrives the precalculated position, the photoelectric sensing locator sends signal to controller, and controller stops the rotation stubborn hand, twist to rise on hand and reset, push rod falls after rise, and previous pallet falls back on the delivery roll, and preceding interception post falls and no longer stops previous pallet, tank body moves ahead on delivery roll with previous pallet, simultaneously, back interception post falls, and a back pallet moves ahead, repeat the process that screws of previous pallet upper tank body, automatically screw the gas head so one by one, no longer with manually screwing, and degree of tightness is very accurate.In addition, twist hand and be connected, when stubborn hand and tank body height do not match, can regulate by the adjusting lifting motor with lifting motor.And the bottom surface of pallet rear and front end has groove, and the position of the position of pallet groove and front and back interception post is complementary, and makes when pallet is blocked very stable.

Description of drawings

Fig. 2 is the structural representation of pallet.

The specific embodiment

Be described in further details below in conjunction with the structure and the use principle of drawings and Examples the utility model Dry Chemical Extinguisher Screwing Device.

As shown in Figure 1, the utility model Dry Chemical Extinguisher Screwing Device comprises several delivery rolls 1, delivery roll 1 is provided with the pallet 3 that holds dry powder extinguisher tank body 2, tank body 2 has gas head 4, be provided with the stubborn hand 6 of band ultrasonic sensor 5 above the delivery roll 1, photoelectric sensing locator 7 and torque sensor 8, twisting hand 6 is connected with motor 10 by reductor 9 with torque sensor 8, twisting hand 6 also is connected with lifting motor 11, twist between hand 6 and the delivery roll 1 and be provided with left tong 12, right tong 13, delivery roll 1 with matching part, stubborn hand 6 position be provided with before interception post 14, back interception post 15, preceding proximity transducer 16, back proximity transducer 17 and push rod 18, ultrasonic sensor 5, twist hand 6, photoelectric sensing locator 7, torque sensor 8, reductor 9, motor 10, left side tong 12, right tong 13, preceding interception post 14, back interception post 15, preceding proximity transducer 16, back proximity transducer 17 is connected with controller 19 respectively with push rod 18.As shown in Figure 2, the bottom surface of pallet 3 rear and front ends has groove 20, and the position of the position of groove 20 and front and back interception post 14,15 is complementary.

When screwing, when tank body 2 runs to interception post 15 places, back with previous pallet 3 on delivery roll 1, back interception post 15 stops previous pallet 3, back proximity transducer 17 is transported to controller 19 with signal simultaneously, after via controller 19 confirms that the main attack position does not have pallet 3, controller 19 sends signal, back interception post 15 falls, previous pallet 3 advances to the main attack position and is stopped by preceding interception post 14, simultaneously, back interception post 15 can stop a back pallet 3 ', to avoid influencing tank body 2 powder fillings on the previous pallet 3.After previous pallet 3 is stopped by preceding interception post 14, preceding proximity transducer 16 is transported to controller 19 with signal, controller 19 sends signal, push rod 18 under cylinder action with previous pallet 3 jack-up, left side tong 12, right tong 13 clamps tank body 2, ultrasonic sensor 5 makes stubborn hand 6 turn to gas head 4 equidirectional by controller 19, twist hand 6 declines then and block gas head 4, then under the effect of motor 10 and reductor 9, twist hand 6 and begin to drive 4 rotations of gas head, this moment, tank body 2 was clamped motionless, after waiting to reach predetermined torque, torque sensor 8 sends signal to controller 19, controller 19 sends instruction, left side tong 12, right tong 13 unclamps, tank body 2 is with 6 gentle 4 together rotations of stubborn hand, after treating that gas head 4 arrives the precalculated position, photoelectric sensing locator 7 sends signal to controller 19, controller 19 stops the rotation stubborn hand 6, twisting hand 6 risings resets, push rod 18 falls after rise, and previous pallet 3 falls back on the delivery roll 1, and preceding interception post 14 falls and no longer stops previous pallet 3, tank body 2 moves ahead on delivery roll 1 with previous pallet 3, simultaneously, back interception post 15 falls, and a back pallet 3 ' moves ahead, repeat the process that screws of previous pallet 3 upper tank bodies 2, automatically screw gas head 4 so one by one, no longer with manually screwing, and degree of tightness is very accurate.In addition, twist hand 6 and be connected, when stubborn hand 6 does not highly match with tank body 2, can regulate by regulating lifting motor 11 with lifting motor 11.And the bottom surface of pallet 3 rear and front ends has groove 20, and the position of the position of groove 20 and front and back interception post 14,15 is complementary, and makes when pallet 3 is blocked very stable.
