Abstract
In a multi-jointed mechanism for a spinning machine, with sensors (52, 54, 56, 58) for detecting the position of the mechanism elements (22, 24, 28), the sensors (52) are mounted opposite the mechanism elements (22) in such a way that the resolution of a ''sensor (52)/mechanism-element (22)'' measurement pairing is at its highest for a position to be detected. Different positions of the multi-jointed mechanism (20) can thereby be set with the greatest repetition accuracy.
Description
The present invention relates to a kind of multi-jointed gear unit that is used for Spinning Machinery, this mechanism is provided with the plurality of sensors in order to definite each transmission component position, and has at least a sensor and a transmission component to constitute a measurement coupling.
Usually adopt inductance and capacitive transducer to adjust movably spinning parts.Just send the signal of a variation when them to control unit when a certain machine element, can obtain the reproduction of connecting rod element in the operating position of Spinning Machinery by it.
Because the automaticity of Spinning Machinery improves constantly, and mechanically operated validity is also had higher requirement.Therefore need control the working position of transmission component exactly.
According to the present invention, this task is finished like this: each sensor should make the resolution of the corresponding measurement coupling of position to be determined be maximum with respect to the setting of transmission component.This can carry out sensing to the element that has top speed in the multi-jointed gear unit by the sensor that makes a select location that is used for determining multi-jointed gear unit and realize.
Can not only improve the precision of Spinning Machinery like this, and can also in machine is installed, obtain the higher method of work of efficient, because can regulate quickly some position of machine element and last position.
Spinning Machinery of the present invention can be elaborated as follows by accompanying drawing:
Fig. 1: show the multi-jointed gear unit that is in raised position, cop is taken away from Spinning Machinery among the figure.
Fig. 2: show the lowering position of multi-jointed gear unit, wherein new bobbin 18 has been taken and plugged to cop away.
Schematically show several adjacent yarning parts 14 in Fig. 1 and 2, wherein yarn is by on bobbin 18.After the coiling operation finished, described cop was taken away from Spinning Machinery by multi-jointed gear unit 20, and this device is called doffer.Cop 14 is by a crossbeam that is connected with shear arm 24 22 supportings.Crossbeam 22 be positioned in the fastening point on the shear arm 24 sleeve 12 on the support 10 pivoting point above.The pivoting point of the guide rod 26 on this pivoting point and the shear arm 24 is selected like this, promptly when multi-jointed gear unit 20 moves, can make crossbeam produce vertical moving.This can realize by following manner: shear arm 24 lower ends are fastened on the screw shell 28 that wherein is installed with a screw rod 32 rotationally, when the screw rod 32 that is provided with along the Spinning Machinery substantially horizontal rotates, sleeve 28 is just done moving of substantially horizontal together with the lower pivot point of shear arm 24, thereby make crossbeam 22 for vertical movement, this Screw rod bearings is in the sleeve 12 of support 10.
According to Fig. 1, when multi-jointed gear unit 20 was in upper limit position, sleeve 28 was near sensor 56 and 58; And when multi-jointed gear unit 20 was in the lower position, crossbeam 22 was near sensor 52 and 54.Therefore just can find out multi-jointed gear unit by sensor 56 and 58 has arrived its upper limit position, and sensor 52 and 54 then can be found out the lower position of this mechanism.According to the multi-jointed gear unit kinology as can be known, during extreme position, the speed of sleeve is maximum thereon in this mechanism, and when crossbeam was in the lower position, all elements of forming multi-jointed gear unit all reached its maximum speed.This means measure coupling " sleeve 28-sensor 56 " resolution when multi-jointed gear unit is in upper limit position for the highest, and when being in extreme lower position in this mechanism, the resolution of measurement coupling " crossbeam 22-sensor 52 " is for the highest.Thereby as can be known, control gear 40 has the highest repeatability when multi-jointed gear unit 20 is in its limit position.
Be arranged to right sensor and determine that multi-jointed gear unit 20 position in all cases is more favourable, thereby just be provided with sensor 54 at the contiguous place of sensor 52; Contiguous place at sensor 56 is provided with sensor 58.
In the lower position of doffing crossbeam, when sleeve 28 entered the receptive field of sensor, sensor 52 can make motor 30 switch to low-speed running from fast turn-around by control gear 40.Control unit should be designed to make motor 30 according to the be used for cut-out of motor program by sensor among Fig. 2 54 or 54a, thereby multi-jointed gear unit 20 is stopped immediately.
