Description

A kind of bar axis-radial high-speed flexible conveyer and transfer approach

Technical field

The present invention relates to production tooling field, particularly relate to one and bar is converted to high speed radial motion state by high speed shaft to state of kinematic motion, and the bar providing satisfied flexible transmission to require axially is braked and the conveyer of radial acceleration capability, being realize the handing-over of rapid wear bar and the place of transmission for high-efficiency flexible in high-speed motion specifically, entering filter tip tipping technique etc. continuous high speed as transmitted after plume rolled forming.

Background technology

The processing of bar product generally has axial and radial two class processing technologys, and thus it produces machine usually by axially can transmitting the upstream machine of bar and can the downstream machine of radial transfer bar forming, both L-shaped layouts.Bar conveyer is the transition mechanism connecting upstream and downstream machine, its effect is that bar is converted to high speed radial motion state by high speed shaft to state of kinematic motion, key problem in technology is to provide bar axially braking and the radial acceleration capability meeting technological requirement, realizes soft transmission.Especially for by being similar to the bar product of granular material parcel very easily because velocity variations sharply and handing-over collision cause end pellet to come off or the equivalent damage that ruptures, as needed device and the technology of using the soft transmission of high speed by rolling technology when tipping technique is changed in high speed cigarette cigarette.

The pacing factor realizing the soft handing-over of high speed ensures that the grabber of conveyer is synchronous with the axial motion of bar, and the receptor of conveyer is synchronous with the radial motion of bar, and bar can not damage because of kinetic factor simultaneously.Existing typical technology has biconvex thumb wheel-Bu Liao drum mechanism and spider-accept drum mechanism etc.Biconvex thumb wheel-Bu Liao drum mechanism is the conveyer that first MOLINS company of Britain PASSIM series rolling up and connecting machine uses.In this type of mechanism, bar is obtained axially by biconvex thumb wheel and radial speed and send into rotation catch in material wheel bearing material groove, and the negative pressure hole in groove provides braking adsorption affinity make bar stop axial motion gradually and be transmitted to splicing drum.There is " material casting " action unavoidably in the cam of biconvex thumb wheel-Bu Liao drum mechanism, its functional reliability is reduced, is difficult to use in the transmission of many rails bar when the bearing material groove of catching material wheel transmits bar.On the other hand, the adsorption affinity that this type of mechanism utilizes the negative pressure hole in bearing material groove to provide realizes the axis braking of bar, stopping distance is short, slows down too fast, cause the material granule preshoot in bar, there are quality problems such as " bears ", stopping distance is long then directly causes the oversize of mechanism, and has bar break stop position to be difficult to the problems such as accurately control, and the braking friction between bearing material groove and bar also usually causes the cosmetic injury of product.Spider is a kind of conveyer based on planet circular system technology that first German rainbow (HAUNI) company PROTOS series rolling up and connecting machine uses.The suction pawl of spider does translation along elliplicorbit all the time, identical with the axial velocity of bar at the tangential speed of the semi-minor axis position of its path of motion, tangential speed in major semiaxis position is consistent with the tangential speed of bearing material groove on splicing drum, thus realizes the axis-radial transfer of bar.In order to meet the requirement of High Speed Transfer, spider hand mechanism generally needs multiple suction pawl, belongs to complicated multirow star-wheel composite structure, design difficulty and manufacturing cost high, and the adaptive capacity transmitted change and many rails bar of bar product length size is poor.On the other hand, because spider hand mechanism must complete bar by the conversion of high speed axial motion to high speed radial motion within the time of inhaling pawl rotation 1/4th elliptic arcs, bar must bear acceleration/accel load sharply, easily causes the quality problems such as product bear and fracture to occur.
