Detailed Description
To explain technical contents, structural features, and objects and effects of the technical solutions in detail, the following detailed description is given with reference to the accompanying drawings in conjunction with the embodiments.
The invention provides a yarn breakage detection method for a horizontal knitting machine, which is used for detecting whether a horizontal knitting machine is broken, is mainly suitable for a spindle arrangement mode of 1F1E, particularly can realize timely finding whether yarn breakage occurs through a mode of visual observation by a user or a mode of detection by a detection mechanism 303, and can ensure that all the yarn breakage conditions can be detected by the method without missing any yarn breakage time.
Referring to fig. 1, in an embodiment, the method for detecting yarn breakage of a horizontal knitting machine includes the following steps:
step S101: detecting whether the yarn feeding wheel 301 sags to the lowest point;
if yes, go to step S102: and judging the yarn breaking.
When the yarn 4 is wound on the yarn feeding wheel 301, the tension of the yarn 4 is the pulling force for pulling the yarn feeding wheel 301, so that the yarn feeding wheel 301 is lifted, in the weaving process, the required amount of the yarn 4 is different, the required amount of the yarn 4 is suddenly changed from large to small or from small to large, and in order to ensure that the yarn 4 is tightened, the yarn feeding wheel 301 reciprocates up and down, so that the yarn 4 is tightened under different yarn feeding amounts in the weaving process; when yarn breakage or yarn absence occurs, the yarn feeding wheel 301 is not under the action of the tension of the yarn 4, and under the action of the elastic member 304 (such as a spring) in the spindle body 300, the yarn feeding wheel 301 directly hangs down to the bottom end of the spindle body 300, that is, the yarn feeding wheel 301 hangs down to the lowest point, so when the yarn feeding wheel 301 hangs down to the lowest point, the yarn breakage may occur, that is, the yarn breakage occurs, and the yarn feeding wheel 301 inevitably hangs down to the lowest point.
According to the working process of the yarn feeding wheel 301, it can be known that all the yarn breakage conditions can be detected in the step S101, any yarn breakage time can not be missed, and whether yarn breakage occurs or not can be timely found in a mode of visual observation by a user in the step S101 or a mode of detection by the detection mechanism 303, so that the judgment standard of yarn breakage is converted into a clear and visible change.
In order to save labor and facilitate and timely detection of yarn breakage, in a further embodiment, in the step of "detecting whether the yarn feeding wheel 301 drops to the lowest point", the detection is performed by a detection mechanism 303, that is, the detection of whether the yarn feeding wheel drops to the lowest point is realized by means of a device, the detection mechanism 303 may be a sensor, such as a distance detection sensor, or may be a travel switch, the travel switch is connected to the horizontal knitting machine, and when the yarn feeding wheel 301 drops to the lowest point, the yarn feeding wheel 301 toggles the travel switch, that is, the travel switch detects that the yarn feeding wheel 301 drops to the lowest point, and the horizontal knitting machine is controlled to stop.
In a further embodiment, after the step "if, then determine yarn breaking", the method further comprises the steps of:
an alarm is issued.
Through the step, when the yarn breakage is judged, a user can be informed, so that the user can stop the horizontal knitting machine and solve the yarn breakage condition.
In the weaving process, because the required amount of the yarn 4 is suddenly reduced from large to small, in order to ensure that the yarn 4 is tightened, the yarn feeding wheel 301 also hangs down to the lowest point, that is, the yarn feeding wheel 301 hangs down to the lowest point includes two situations, one situation is yarn breakage, and the other situation is that the required amount of the normal yarn 4 is suddenly reduced from large to small, in order to avoid misjudgment, the situation that the yarn feeding wheel 301 hangs down to the lowest point due to the sudden reduction of the required amount of the normal yarn 4 needs to be eliminated, in a further embodiment, in the step "detecting whether the yarn feeding wheel 301 hangs down to the lowest point", in the motion period of the yarn feeding wheel 301, the detection is performed when the yarn feeding wheel 301 is not at the lowest point.
Through the step, the yarn feeding wheel 301 can be ensured to be in a broken state if the yarn feeding wheel drops to the lowest point, so that the accuracy of the detection method is improved.
In order to further increase the accuracy of the detection method, in a further embodiment, in the step "detecting whether the yarn feeding wheel 301 drops to the lowest point", the detection is made when the yarn feeding wheel 301 should be at the highest point during the movement cycle of the yarn feeding wheel 301.
Through the steps, the situation of misjudgment can be avoided to the maximum extent.
The movement locus of a single group of spindles is shown in fig. 4, the movement locus is divided into clockwise spindle bodies 300 and anticlockwise spindle bodies 300 which form S-shaped winding movement at the end of a knitting machine, the installation positions of the spindle bodies 300 on a dial 2 are different, the formed yarns 4 are also different, the arrangement mode in the knitting process generally comprises three modes of 1F1E, 2F2E and 1F3E, wherein, E and F respectively indicate that the spindles with the same movement direction set the vacant positions or the spindles placed according to the sequence of notches on the dial, and the spindle bodies 300 in fig. 4 are arranged in a mode of 1F1E spindles, and in the arrangement mode, two adjacent spindle bodies 300 in the same group are different by half period. In the weaving process of the spindle bodies 300 moving clockwise or counterclockwise, if the spindle bodies 300 pass through the sensor, after one spindle body 300 passes through the sensor, the next spindle body 300 also passes through the sensor after a half cycle.
In a certain period, the yarn feeding wheel 301 moves up and down under the action of tension of the yarn 4, and the release length of the carbon fiber at the outlet of the spindle influences the limit value of the up-and-down position of the movement of the yarn feeding wheel 301. During the knitting process, the convergence distance H (see H in fig. 7) between the knitting point b (see b in fig. 7) and the spindle outlet E (see E in fig. 7) can be calculated by the following formula (1):
wherein α is a knitting angle (see α in fig. 8), and the knitting angle is an angle formed by the yarn 4 and the axis of the core mold 5; (x)E,yE) Is the coordinate value of the spindle outlet E; r is the mandrel 5 radius.
And further calculating the linear distance ld from the spindle outlet to the knitting point as follows:
in the formula IxThe radial distance from the spindle outlet E to the center of the knitting machine.
Thus, the release length delta l of the carbon fiber at the spindle outlet E is obtainedcComprises the following steps:
in the formula,. DELTA.laThe length of time Δ t at which the fibers are wound onto the surface of the mandrel 5.
From the above formula, the relationship between the fiber length released from the ingot in one period and the time can be obtained as shown in fig. 2.
According to the variation trend of the fiber releasing length of the spindle obtained through the process, the upper and lower position limit values of the motion of the yarn feeding wheel 301 are influenced by the carbon fiber releasing length at the outlet of the spindle, and are in a proportional relation, namely the longer the carbon fiber releasing length is, the higher the position of the yarn feeding wheel 301 is, the shorter the carbon fiber releasing length is, the lower the position of the yarn feeding wheel 301 is, if the carbon fiber releasing length is the shortest, the yarn feeding wheel 301 may be at the lowest position, and it can be known from fig. 2 that the longest value of the carbon fiber releasing length is located in 1/4-1/2 in one period, specifically, the maximum value reaches the peak value when the carbon fiber releasing length is close to 3/8, and the yarn feeding wheel 301 is in the state close to the maximum point.
