Description
Technical field
The present invention relates to a kind of warp doffing machine structure of automatic doffing roving frame, relate in particular to a kind of steel band revolution warp doffing machine structure of automatic doffing roving frame.
Background technology
The built-in automatic doffing roving frame used in prior art, when doffing, promote the lift spindle bar by cylinder and turn round to carry out and get yarn or put pipe action, then by chain, will expire yarn and be delivered to the automatic doffing roving frame tail.Because of the controlling unit complexity, the more problems of appearance, the success rate of doffing is difficult to reach standard-required.
Chinese patent application CN103215707A discloses a kind of flyer bobbin plug-in mounting structure of automatic doffing roving frame, it starts pin by taking to be arranged with the first startup pin and second on bobbin holder top, the flyer bobbin bottom is evenly equipped with two above even number taper pin grooves, each taper pin groove on flyer bobbin and first starts pin and the second startup pin is corresponding, the first diameter D1 that starts pin is greater than the diameter D2 of the second startup pin or/and first start the version of the center line of pin higher than the center line of the second startup pin, make to move and doff Speed frames when automatic doffing, taper pin groove on flyer bobbin can accurately be inserted in two of bobbin holder and start pin, can improve the accuracy of intubate.
The plug-in mounting structure of this kind of version, can play the technique effect that improves the intubate accuracy to a certain extent.But the version that this startup pin and taper pin groove position by insertion, because the aperture size that starts bearing pin footpath and taper pin groove is all very little, thereby must carry out precise positioning with the taper pin groove to starting pin before grafting, and the control of this location requires high, and control procedure is also relatively complicated; And, because the intubate total quantity is a lot, the total quantity that correspondingly starts pin is also a lot, is prone in use procedure and is wound around phenomenons such as hanging yarn.
Chinese patent application CN102758909A discloses a kind of combined wheels for the automatic doffing roving frame Steel Belt Transmission, by utilizing metal wheel body supporting steel band, and the frictional force that between rubber ring and steel band, generation is larger can not produce slip to guarantee that the metal wheel body drives when steel band rotates, and make the steel band accurate positioning, improve the operational efficiency of automatic doffing roving frame.
Adopt technique scheme, in the technical problem that solves the steel band location, objectively also can the accuracy that improve intubate be played a role.But because only relying on steel band, it with combined wheels, directly contacts, withstand steel band to prevent the monolateral lateral displacement of steel band by combined wheels, this supporting and location only plays interception when combined wheels one side occurs to break away to steel band, for steel band, due under the elongated or lax state that is stretched, steel band may occur to the sideslip that deviates from combined wheels one side generation helpless.Therefore, it is very limited for improving the automatic doffing roving frame effect that the accuracy of intubate plays when the automatic doffing.
The external automatic doffing roving frame used in prior art, when doffing, the spool exchange is to realize by the spool interchanger on the spool switching plane, one of most critical parts of spool interchanger are pipe-grabbing mechanical arms, when the relative high and low position of pipe-grabbing mechanical arm on the spool interchanger determined the spool exchange, the uniformity of manipulator behavior, therefore determined the success rate that spool exchanges.
Chinese patent application CN203112996U discloses a kind of external automatic doffing roving frame, it is existence and the equipment problems such as nut loosening that inevitably exist in service due to rigging error for the external automatic doffing roving frame, the position of setscrew nut on screw rod is difficult to remain uniformity, thereby just do not guarantee the uniformity of pipe-grabbing mechanical arm location on these spool interchangers yet, and then affect the effect that pipe-grabbing mechanical arm captures spool, affect the technical problem of the success rate of spool exchange, by adopting the pipe-grabbing mechanical arm with the setting height(from bottom) setting element, the linear guide rail type down rail shifts out slideway and perfect location and safeguard measure, pipe-grabbing mechanical arm high and low position on the spool switching plane is guaranteed, down rail shifts out and resets and operates steadily, position location is more accurate, stability and the reliability of automatic doffing have been improved.
In sum, solve automatic doffing roving frame how on the technical problems such as the accuracy of automatic doffing process, stability, reliability, prior art has provided the technical solution of various ways.But, the technical solution of the various ways that prior art has provided more or less exist technological means single, lack systematicness, the deficiency of the aspects such as the technical scheme of perhaps dealing with problems is complicated, operation and controlling is difficult, particularly install in use procedure and be difficult to guarantee that it remains good stability and uniformity.
