Description

The motion of two-sided weaving loom attending device

The present invention relates to the motion of two-sided weaving loom attending device, the free-end spinning machine that particularly has running rail, the interior guide rail and the follower rail that comprise two straightways are installed corresponding to spinning machine longitudinal axis symmetry, and connect the guide rail straightway with a semicircular track in its spinning machine end at least, have and be arranged on the operation wheel that is assemblied in the motion at least two guiding devices on the running rail, its guiding device is installed on the attending device, to be suitable for turning, and guider is housed, this guider has inboard and the outside guiding mechanism that is supported by its associated guide tracks, this guider comprises at least one group of directive wheel, wherein two inboard directive wheels are by inboard guide rail support, and two outside directive wheels are supported by follower rail.

The motion of the attending device that some are known described in DE2118775, is used to guide two guide wheels of the operation wheel on the attending device as spinning machine part, article one, above being positioned at, and below another is positioned at, yet following track can hinder the operator to use machine.

For avoiding this defective, in DE2516004, attending device then moves on the main guide rail that is positioned at above the spinning machine operation part; For keeping balance, the lower track in position is comprised that by one the auxiliary rail that is set directly at the short groove on the spinning mechanism shell replaces, and tilts to prevent auxiliary wheel.Because the spinning mechanism shell is easy to perk and moves, attending device is having when spinning machine moves by badly damaged danger, and promptly attending device is just in case enter spinning mechanism and have in the shell of opening or auxiliary operation wheel arrives the functional unit of split decapsidate.In addition, the two ends that in the two-sided spinning machine of cyclical patterns and service equipment, should safeguard weaving loom, at least one end of the straightway of main supporting track is linked to each other by a semi-circular piece so that attending device can be from a lateral movement of weaving loom to opposite side.In this section, Auxiliary Track must by spinning machine in the other direction the auxiliary semi-circular piece on the active position substitute, it can absorb the vibration that is produced when attending device enters without restrictions section by the spinning machine end.But, the very complicated and difficult manufacturing of this structure.

Above-mentioned part shortcoming can be in CS AO 243076 be partly eliminated in the motion of disclosed attending device, this weaving loom comprises a supporting track that is installed on the spinning machine, it has two straightways installed with symmetric form corresponding to the spinning machine longitudinal axis and at least one circular piece of spinning machine end two straight line portioies is connected, and comprise that also Auxiliary Track is positioned on the spinning machine longitudinal axis plane always, be used to guide the supporting operation wheel of attending device.This supporting operation wheel is installed in the single-revolution axis and is positioned on the rotation underframe that supports operation wheel radial central plane, and attending device is installed on the underframe with suspension type with pivot pin.Operation wheel with wedge-shaped slot is pressed on the supporting track with circular cross-section.

When the circle segments, the operation wheel freely rotates around the spherical bearing axis, and it moves to take turns and is positioned on the spherical bearing, in this case, bogie wheel stop operating and attending device around pivot pins.

Hence one can see that, when the circle segments of process supporting track is taken turns in operation, can cause the speed wearing and tearing of braking action and contact surface because of the shearing friction of taking turns the generation of wedge-shaped slot surfaces externally and internally peripheral speed difference and circular orbit place.In addition, between moving period, particularly on the straight line portion of supporting track,, can't prevent to offer the spontaneous rotation of operation wheel at attending device owing to the result of various force reactions.

The motion of describing in CS AO 264244 has then been eliminated above-mentioned shortcoming, operation wheel with cylindrical sides is installed on the guide member, and guider is housed, this device comprises the directive wheel that at least one group of axis parallels with the guide member axis, comprises that also one uses and is positioned at the other guide rails of running rail for above-mentioned directive wheel.Be tangential to the circulatory motion course bearing of operation wheel, the then equidistant above-mentioned auxiliary plane both sides that are positioned at of second, third axis of taking turns.

This structure helps the operation wheel with accurate direction motion, and can eliminate the defective of above-mentioned known embodiment.But its shortcoming is: the width of bend place auxiliary guide rail is different from the guide rail width at straightway place certainly, and promptly with regard to auxiliary guide rail, guide rail must be widened or narrows down according to the installation form of directive wheel.One directive wheel is positioned at its inboard if two directive wheels are positioned at the bend outside, just must widen the auxiliary guide rail at the bend place; One directive wheel is positioned at the bend outside if two directive wheels are positioned at curve inner side, and auxiliary guide rail is narrowed down.The bend of different in width not only is difficult for making but also having increased manufacturing expense.

The objective of the invention is to form a kind of motion of attending device, this bend section width of bend section that the guider of its guiding device can move auxiliary guide rail is identical with the width of auxiliary guide rail straightway.

The invention provides the motion of two-sided weaving loom attending device, the free-end spinning machine that particularly has delivery track, it is equipped with a running rail, an interior side rails and a follower rail, it comprises two straightways of installing with symmetric form corresponding to the spinning machine longitudinal axis, and the straightway guide rail that connects this machine end with at least one semicircular feature, at least two operation wheels of motion are arranged on the guide rail, each directive wheel all is installed on the guiding device to be suitable for the operation of attending device, and be equipped with directive wheel and be installed in guider on the guide rail, guider wraps one group of four directive wheel at least, wherein two inboard directive wheels are positioned on the guide rail, two outer directive wheels are positioned on the outer guide, it is characterized in that: in horizontal plane, the line of the line of the two axial lines intersection point of left side directive wheel and the two axial lines intersection point of right hand guide wheels intersects at a point on the plane of spinning machine longitudinal axis, promptly, the line of the intersection point on the axis of directive wheel and above-mentioned plane outside the intersection point on the axis of directive wheel and above-mentioned plane and the left side in the left side intersects at a point on the plane of spinning machine longitudinal axis with the axis of directive wheel and the line of above-mentioned plane point of intersection outside the intersection point on the axis of directive wheel in the right side and above-mentioned plane and the right side.

The advantage of the motion of this attending device is the motion that motion can be smooth and can reduces the wearing and tearing of motion parts.

Another advantage is that in all orbital segments spacing equates to be easy to manufacturing and to reduce cost between two guide rails.

Guide rail can tilt mutually and the directive wheel of guider can be made into cylindrical, taper or cydariform.

The embodiment of the motion of the two-sided weaving loom attending device of the present invention will be illustrated in conjunction with the accompanying drawings.
