Yarn winding apparatus comprises that also being used for detecting yarn is around in detecting device 130 on the friction roller 120 unusually.This detecting device 130 comprise be positioned near the friction roller 120 with ray cast light projector 131 on the circumferential surface 121 of friction roller 120, a light receiver 132, it is positioned at friction roller 120 and light projector 131 neighbouring with receive from light projector 131 projections and by the light of yarn 101 reflections that are around in friction roller 120, a control circuit 135 and definite device of Yarn winding apparatus, it has formed the part of control circuit 135, so that determine according to the light quantity of light receiver 132 receptions whether yarn 101 is around on the friction roller 120.
The surface color of friction roller 120 will be not easy to surface 121 reflected light rayss by friction roller 120.Can comprise a friction roller 120 according to Yarn winding apparatus of the present invention, its black surface is not easy to surface 121 reflected light rayss by friction roller 120.Light projector 131 and receptor 132 are loaded in the common container 133, and this container 133 is positioned near the of friction roller 120 and is electrically connected with a testing circuit 134 that forms control circuit 135 parts.Testing circuit 134 be configured to export an electric signal in case with ray cast on the circumferential surface 121 of friction roller 120 and along with light is imported an electric signal by light projector 131 projection and after by yarn 101 reflections that are around in friction roller 120 by light receiver 132 receptions.Testing circuit 134 is designed to link with definite device, and should determine whether device is around on the friction roller 120 according to the light quantity decision yarn 101 that light receiver 132 receives.The reason that friction roller 120 is processed to have black surface be not easy to surface reflection line by friction roller 120 so that can not import the light that receives along with light receiver 132 electric signal that produces.Exceeded under the situation of a predetermined value in the light quantity that receives by light receiver 132, electric signal is not imported in the testing circuit 134 effectively, if the light quantity that is received by light receiver 132 has exceeded predetermined value then electric signal is imported in the testing circuit 134 on the contrary to produce a unusual condition signal.This unusual condition signal is imported in definite device of control circuit 135 to determine normal and unusual coiling situation.For this reason, be provided with control circuit 135 definite device in case the light quantity that receives according to light receiver 132 determine yarn 101 unusual coilings or be not around on the friction roller 120.Many loop yarn wire-wounds are on friction roller 120 in the present embodiment according to Yarn winding apparatus of the present invention, set the predetermined value that light receiver 132 receives light quantities, it is extremely sensitive that this does not just need 132 pairs of receptors 132 of light receiver to be sensitive to the such degree of an only circle on the friction roller 120.
Yarn winding apparatus also comprises a yarn cutter, not shown, be suitable for the pre-position chopped strands 101 on a path of travel of yarn 101, yarn 101 is in path of travel feeding bobbin 102, also comprise yarn cutter handling device, the part that it forms control circuit 135 is used for according to the unusual condition signal operation yarn cutter that comes definite device of self-forming testing circuit 134 parts, when being around on the friction roller 120 unusually with convenient yarn 101 leading section of yarn 101 is cut off from the yarn 101 that is around in friction roller 120 unusually.
Yarn winding apparatus often runs into such problem, promptly, the operator is not hooked to the front end of yarn 101 on the bobbin 102 before yarn 101 begins to be around on the bobbin 102, thereby the front end that causes yarn 101 advances so that is around on the friction roller 120 rather than on bobbin 102 through friction roller 120 and bobbin 102 probably, automatically is not hooked on the bobbin 102 and produces similar problem because Yarn winding apparatus is operated to the front end of yarn.In another case, if Yarn winding apparatus is owing to certain external force that is applied on the Yarn winding apparatus causes that vibration and collision yarn package 103 break away from wipe contacts with friction roller 120 probably immediately, thereby cause yarn 101 to be around on the friction roller 120.Yarn 101 at first with coarse mesh form shown in dotted lines in Figure 8 directly on friction roller 120, rotate then with bobbin 102 at high speeds subsequently and twine with fine and close mesh form.At last, a large amount of yarn packages can be arranged on friction roller 120, this just may cause that the motor 125 that is used for friction roller 120 stops owing to its overload or cause that the yarn package on the friction roller 120 bumps against with some parts that is adjacent to friction roller 120.
Therefore, be yarn 101 when being around on the friction roller 120 under Yarn winding apparatus is defined in unusual condition, the yarn cutting operation device that forms control circuit 135 parts according to the unusual condition signal operation yarn cutter of the definite device that comes self-detection circuit 134 so that the front end of yarn 101 cut off from the yarn 101 that is around in friction roller 120 unusually.When the yarn cutter is operated chopped strands 101 because the leading section of the yarn 101 that cuts off from the yarn that is around in friction roller is failed to be around on the friction roller, unusual yarn package on friction roller can not thickening, thereby can not produce the mechanical part of Yarn winding apparatus and damage.
On the other hand, be in yarn and be around on the friction roller 120 this unusual condition following time, the control circuit 135 of Yarn winding apparatus thereby drive motor 125 is stopped so that not driving friction roller 120 when Yarn winding apparatus is determined.For example resemble an alert light modulation and the such alarm instrument of siren horn if Yarn winding apparatus has, then the operator can recognize rapidly that yarn 101 has been around in the fact such on the friction roller 120.Therefore be appreciated that this Yarn winding apparatus can avoid foregoing problem easily.
Therefore, definite device of control circuit 135 determines according to the light quantity that optical receiver 132 receives whether yarn 101 is around on the friction roller 120 unusually, when the yarn 101 of scheduled volume is on friction roller 120 by yarn cutter handling device operate yarn cutter so that yarn cut off from the yarn that is around on the friction roller 120.Therefore, Yarn winding apparatus can carry out automation doff operation, and this automation doff operation comprises that the leading section with yarn 101 is hooked on the circular groove of bobbin 102 so that the yarn that the front end of yarn 101 is caught by 102 circular groove hooks up step and will expire yarn package 103 and throw off a bobbin change step changing full yarn package 103 with the bare bobbin 102 in succession of applying from spool stand 115.
In addition, when multi-turn yarn 101 is the yarn 101 of scheduled volume when being around in friction roller, start detection device 130 cuts off yarn 101 to produce a signal.As a result, can not make and detect the yarn 101 generation maloperations that are around in friction roller 120, thereby, make detecting device 130 with quite low-cost manufacturing.
