Abstract

A novel fixed point rejecting device of a cigarette packing apparatus consists of a box, a fixed frame, a cam connecting rod mechanism and a pneumatic on-off mechanism. The box and the fixed frame are installed on the packing apparatus. The cam is installed on an outlet axle of a main engine in the box. Sliding wheels and a hook pin are installed on a swinging arm and are articulated with the connecting rod. A pushing rob is articulated on the connecting rob. The fixed frame is provided with two groups of runways of pushing rod. Each group of the runways is provided with four rolling-bearings to support the four faces of the pushing rod. A two-position and five-way magnet valve is installed on an in-out gas pipe of a cylinder. When the valve receives the rejecting signal, a piston rod of the cylinder ejects out. Therefore, the hook breaks away the hook pin and the swinging arm swings with the cam to push the pushing rod, so as to reject the defective products. The utility model replaces the magnetic on-off of the original device with the pneumatic on-off, replaces a prior bakelite sleeve with the runways consisting of rolling bearings, which overcomes the disadvantages of failing to work normally caused by remanence, abrasion of thin teeth and feculency blocking on the runways and is a good improvement of the packing apparatus.

Description

New cigarette wrapping machine fixed point device for eliminating

One, technical field:

The utility model relates to a kind of device for eliminating of cigarette packer off gauge, 10 device for eliminating of specifically a kind of New type of S ASIB6000 type cigarette packer.

Two, background technology:

10 device for eliminating of existing Italian import SASIB6000 type cigarette packer adopt magnetic clutch to add the eccentric wheel transfer bar mechanism, detector is passed to magnetic clutch by computing machine with the information of off gauge and is made its engagement, the rotation of drive eccentric wheel, the push rod action weeds out the off gauge that just in time is in 10 stations.Facts have proved that there is following shortcoming in such mechanism:

1, require magnetic clutch precision height, existing home made article quality does not pass a test, and the import power-transfer clutch is very expensive again.

2, magnetic clutch often produces remanent magnetism, and the outage back is difficult for throwing off; The closely-pitched of power-transfer clutch is easy to wear again; Be subjected to the impact mounting screw of folding easily loosening for a long time, rupture; To be two axles cooperates with bakelite cover on the support push rod slideway, and when generation greasy dirt or dust, the pusher slide dynamic resistance is very big, moves insensitive.In a word, because of its structural defective causes the complete machine unstable working condition, fault is many, and the maintenance of stopping is frequent, causes damage to production.

Three, summary of the invention:

The purpose of this utility model is to provide a kind of new cigarette wrapping machine fixed point device for eliminating that can overcome above-mentioned shortcoming.

This utility model is achieved in that

New cigarette wrapping machine fixed point device for eliminating is made up of casing, fixed mount, cam link mechanism and pneumatic engaging and disengaging gear, and casing and fixed mount are contained on the fuselage.Cam link mechanism comprises cam, swing arm, arm shaft, roller, connecting rod, push rod, spring and push rod slideway, cam is contained on the interior host output shaft of casing, when main frame starts, swing with host output shaft, arm shaft is fixed on the box body wall, one end of swing arm has axis hole, be contained on the arm shaft, sliding joining is the fulcrum of swing arm activity, roller arranged in the swing arm, strike out, roller is contained on the roller shaft in the swing arm, sliding joining, when swinging arm, can mesh the other end of swing arm and rod hinge connection with cam curved surface.Two groups of push rod slideways are housed on the fixed mount, every group of slideway is made up of four antifriction-bearing boxs that are contained in the locating piece of the band minor axis on the fixed mount and are contained on the minor axis, two groups of slideways divide two places supporting four faces of push rod, one end and the rod hinge connection of push rod, the other end is equipped with push rod cup, between swing arm articulated linkage end and the fuselage, spring is housed along the connecting rod trend; Air clutch mechanism comprises: cylinder, hook, strike out, hook axle and hang spring, hook axle, cylinder are contained on the body, axis hole is arranged in the hook, be contained on the hook axle, sliding joining becomes the moving fulcrum of hook, and hook one end is that striking out in eave tile and the swing arm matches, articulated cylinder piston rod between eave tile and the hook fulcrum has the extension spring on the other end of hook.Its principle of work is such: on the turnover tracheae of cylinder two-position-five-way solenoid valve is housed, the control of the examined device of this electromagnetic valve, when not rejecting signal, cylinder piston rod is failure to actuate, hook hangs over striking out of swing arm, this moment cam under host output shaft drives, about ceaselessly swing, striking out because of being subjected to the control of hook eave tile in the swing arm, swing arm is motionless.After electromagnetic valve is received the rejecting signal, the electromagnetic valve action, cylinder piston rod ejects, hook with strike out disengagement, swing arm is under action of the spring, the roller on it leans against on the curved surface of cam outer, swing arm is swung with cam, and the rejecting operation of 10 off gauges on the station is finished in connecting rod, push rod action.When rejecting blackout, electromagnetic valve moves, and cylinder piston rod resets, and hook hangs over striking out of swing arm again, and roller and cam are thrown off, push rod stops swinging.

Adopt the utility model to overcome a series of problems that magnetic clutch brought of using, after slideway in the fixed mount changes the roller slideway into push rod is moved freely in slideway, whole eliminating system is operated steadily, reliably, guaranteed the long-term normal operation of wrapping machine.
