Abstract

The utility model provides a servo driven station shifter of an automatic wrapping machine with the bag method, comprising a servomotor(2) arranged on a main frame. A driven arm(7) of the servomotor is articulated with a connecting rod board(3), and the other end of the connecting rod board(3) is connected with an active swinging arm(1) by a rotating shaft. The other end of the active swinging arm(1) which is connected with an active shaft(8) is arranged on the main frame which has a driven shaft(10). The active shaft(8) and the driven shaft(10) respectively has a swinging arm(4), the lower parts of the two swinging arms has a connection lever(5) and a fixing baseplate. The utility model has the advantages of simple structure, quick running speed, steady running process, and accurate position without impact and vibration.

Description

The switching mechanism of bag forming automatic packaging machine servo-drive station

(1) technical field

The utility model relates to a kind of actuating device.

(2) background technology

Along with the raising of every profession and trade capacity rating, require the also corresponding raising of ability of the wrapping machine of post-processing packing, the packing of chemical industry post-processing has at present proposed 1400 bags/hour (25 kilograms/bag) above requirement to the capacity packing of wrapping machine; The wrapping machine that satisfies this requirement has only this a kind of form of bag forming automatic packaging machine at present, and the conversion rate between each functional station of bag forming automatic packaging machine is an important step that influences the wrapping machine capacity packing, capacity packing reach 1400 the bag/hour more than the time, transfer time between each functional station of bag forming automatic packaging machine is also with regard to about 0.8 second, and it is accurate and stable to require to put in place.

The station switching mechanism of bag forming automatic packaging machine at present is all by driven by power, and this mainly is that mechanism's volume is bigger because be power with pneumatic or hydraulic pressure, and kinematic velocity and response are slower, repeating motion positioning control complexity; Driven by power station switching mechanism at present mainly contains following two kinds of forms, a kind of is that the common braking motor of employing is a propulsion source, when station switching mechanism transposition puts in place, the braking motor braking, pressure allows station switching mechanism stop motion, after this kind mode speed improves, impact shock when station switching mechanism transposition puts in place is bigger, and it is also high to the requirement of reducing motor, want to reduce impact and vibration when putting in place, have only by reducing the total quality that scantling of structure and part material reduce mechanism, thereby reduce motion of mechanism inertia, but this kind mode potentiality are limited, and material becomes behind the alloy in lightweight that the price of part will raise and fabrication properties not as steel component; Another kind is that to adopt common braking motor to add variable-frequency governor be propulsion source, this kind method is to adopt high frequency to improve the motor running velocity when station switching mechanism transposition beginning, when the position, utilize frequency converter that the running frequency of braking motor is reduced, thereby reduce the running velocity of station switching mechanism, treat that operation puts the back in place in the implementation braking, impact and vibration after thereby the reducing mechanism motion puts in place, but it is too many that this kind method high frequency and low frequency can not differ, otherwise low-and high-frequency conversion opportunity structure is very big to the impact meeting of motor, low frequency can not be too low in addition, otherwise influence station switching mechanism transposition speed, also is limited so the kind method improves the space.

(3) summary of the invention

It is a kind of simple in structure that the purpose of this utility model is to provide, and running velocity is fast, and operational process is steady, puts in place accurately, puts in place and do not have the bag forming automatic packaging machine servo-drive station switching mechanism of impacting with vibration.

The purpose of this utility model is achieved in that it comprises the servomotor 2 that is installed on the mainframe, the actuating arm 7 of servomotor is hinged with link rod plate 3, the other end of link rod plate 3 is connected with active swing arm 1 by rotating shaft, initiatively the other end of swing arm 1 is mounted on the active rotating shaft 8 on the mainframe, driven spindle 10 also is installed on the mainframe, the lower end that 4, two servo-actuated swing arms of servo-actuated swing arm all are installed on active rotating shaft 8 and the driven spindle 10 is equipped with pipe link 5 and installation base plate 6.Active rotating shaft and driven spindle are equipped with rolling bearing units 9, and rolling bearing units 9 are fixed on the mainframe.

Device of the present utility model be at the shortcoming of said mechanism with not enough, and the actual demand of industry such as petrochemical complex is developed at present.Be one of principal assembly of bag forming automatic packaging machine.The bag taking of bag forming automatic packaging machine, open bag, pack, mouthful envelope and mouthful the conversion of an envelope bosher interdigit is main finishes by this mechanism.The switching mechanism of bag forming automatic packaging machine servo-drive station mainly provides bag taking, open bag, pack, mouth envelope and mouthful envelope are cooled off each function paw erecting stage of station and are changed the control position of each function paw by beat, servomotor passes through actuating arm, connecting rod is pulled and is driven initiatively swing arm swing, when the operation beginning, servomotor makes initiatively swing arm the utmost point accelerates to certain speed in the short time after with very big acceleration torque square, after servomotor drive active swing arm moves certain hour by this speed, servomotor applies deceleration torque to the active swing arm, making the running velocity when initiatively the swing arm operation puts in place is zero, movement inertia when mechanism's operation is put in place is zero, and then make entire mechanism between two stations of front and back during crank motion, kinematic velocity is fast, and does not have when putting in place and impact and vibration.Device of the present utility model has simple in structure, and running velocity is fast, and operational process is steady, puts in place accurately, and advantages such as not having impact and vibration puts in place.
