Detailed Description
Embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts. Further, although the terms used in the present invention are selected from publicly known and used terms, some of the terms mentioned in the description of the present invention may be selected by the applicant at his or her discretion, the detailed meanings of which are described in relevant parts of the description herein. Furthermore, it is required that the present invention is understood, not simply by the actual terms used but by the meaning of each term lying within.
The basic principles and preferred embodiments of the present invention are discussed in more detail with reference to the accompanying drawings. First, fig. 1 shows a flowchart of an embodiment of a spindle diameter calculating method according to the present invention. The spindle diameter calculation method mainly comprises the following steps:
s1: dividing a spindle (shown in figure 2) into a plurality of layers along the height direction, and setting a diameter array for each layer;
s2: determining the top position of a spinning area (such as the spinning area A in figures 3 and 4) of the take-up at this time, wherein the height of the spinning area is a constant preset value;
s3: respectively obtaining the winding length of the winding and the number of rotation turns of the spindle of the winding;
s4: calculating the diameter of the bottom position of the spinning area of the take-up according to the take-up length of the take-up, the number of rotating circles of the spindle and the top position of the spinning area; and
s5: and updating and assigning a value to the diameter array of each layer in the spinning area of the take-up according to the top position, the bottom position and the diameter of the take-up.
As discussed above, the prior art needs to consider the diameter of the individual yarn, which is not accurately converted by count, and then the diameter of the spinning area is calculated, which is not a simple stack of the diameters of the individual yarns, and if the individual yarns are stacked, the arrangement density of the yarns must be considered, but this data is not available. In contrast, the spindle diameter calculation method of the invention deduces the diameter of the spindle by using the approximate algorithm of the circular truncated cone spiral line, and the diameter of the bottom of the spinning area can be obtained only by recording a plurality of take-up data without introducing and considering the diameter and the winding displacement density of single yarn in the whole calculation process, thereby obtaining the diameter of each layer of the whole spinning area. Therefore, the calculation result of the spindle diameter calculation method is more reliable.
One embodiment of the present invention is discussed in detail below in conjunction with fig. 2-5.
Fig. 2 shows an example of an empty spindle. The empty spindle is in a round table shape with a thin upper part and a thick lower part, and the height of the spindle is S. The yarn bound on the spindle after being wound conforms to the circular truncated cone spiral line, so that a foundation is provided for the invention to deduce the diameter of the yarn by utilizing an approximate algorithm of the circular truncated cone spiral line. According to the present invention, in step S1, the spindle is first divided into a plurality of layers in the height direction, for example, the spindle having a height S of 3200mm is divided into 3200 layers, and a diameter array is set for each layer. In the initial state, the diameter array of each layer corresponds to the diameter of each layer of the empty spindle.
The height of the spinning area a is a constant preset value during the whole take-up process, for example, in the embodiment shown in fig. 3-4, the height of the spinning area a is set to 80mm, and each take-up is completed in the 80mm spinning area.
Fig. 3 to 5 show three stages in the take-up process, respectively. The first stage shown in fig. 3 is a process in which take-up is performed directly on an empty bobbin. Next take-up has a pitch lift, i.e. an upward offset in the height direction, compared to the previous take-up. The value of each increment is not constant. As can be seen from fig. 4, a shaped region B, which is formed as a result of the pitch of several take-ups, appears below the spinning region a. Further, as shown in fig. 5, the final formed spindle will consist of three parts, namely a top approximately frustoconical region C1, a middle columnar region C2, and a bottom approximately frustoconical region C3. The final spindle shape depends on the adjustment of the pitch value.
Due to the pitch, in step S2 of the spindle diameter calculating method described above, it is necessary to determine the top position of the spinning region a where the take-up is performed this time. The top position of the spinning area for taking up the wire at this time is equal to the top position of the spinning area for taking up the wire at the previous time plus the pitch lift at this time. Further, since the spinning process of the entire spindle is gradually moving up the spinning region from the bottom to the top, the diameter at the top position mentioned above refers to the original diameter of the empty bobbin at the top position.
Next, in step S3, the winding length of the current winding and the number of rotations of the spindle of the current winding are obtained respectively. According to a preferred embodiment, the winding length of the current winding can be obtained by collecting the starting position and the ending position of the frame, and the number of rotation turns of the spindle of the current winding can be obtained by recording the starting position and the ending position of the spindle in the winding process. Of course, the present invention is not limited thereto, and those skilled in the art can use other known devices and techniques to collect the above-mentioned winding length and the number of spindle rotations, respectively.
Based on the acquired data, namely the winding length of the winding, the number of rotation turns of the spindle and the top position of the spinning area, the diameter of the bottom position of the spinning area of the winding can be calculated by applying an approximate algorithm of the circular truncated cone spiral line, and step S4.
Preferably, the spindle diameter calculating method of the present invention may calculate the diameter of the bottom position of the spinning area of the present take-up according to the following equation:
Db＝(L*2/(C*π))-Dt
wherein D isbThe diameter of the bottom position of the spinning area of the take-up is shown,l represents the take-up length of the take-up, C represents the number of rotation turns of the spindle, and DtAnd the diameter of the top position of the spinning area of the take-up at this time is shown, and pi is the circumferential ratio.
Then, in step S5, the assignment is updated for the diameter array of each layer in the spinning area of the current take-up according to the top position, the bottom position and the diameter thereof. In addition, in step S5, the step of updating the assignment value of the diameter array of each layer in the spinning area of the current take-up may further include: fitting the spinning area of the take-up as a circular truncated cone; determining a diameter at each layer in the circular table based on the diameter of the top location and the diameter of the bottom location; and reassigning the corresponding diameter array with the determined diameter at each layer. The basis of this calculation is: the shape of the circular truncated cone is an isosceles trapezoid when viewed from the side, and the length of any straight line which is horizontal to the intersection of the upper bottom, the lower bottom and two oblique sides of the trapezoid can be obtained as long as the upper bottom and the lower bottom of the isosceles trapezoid are determined.
Finally, the method of calculating the diameter of the spindle described above may further comprise an iteration step, after the step of updating the assignment. The iteration step includes:
determining the top position of the spinning area for the next take-up according to the pitch lift,
the above-described steps S3-S5 are repeatedly performed.
In addition, each of the embodiments of the present invention can be realized by a data processing program executed by a processing system such as a computer. It is clear that the data processing program constitutes the invention. In addition, a data processing program, which is generally stored in one storage medium, is executed by directly reading the program out of the storage medium or by installing or copying the program into a storage device (such as a hard disk and/or a memory) of the processing system. Such a storage medium therefore also constitutes the present invention. The storage medium may use any type of recording means, such as a paper storage medium (e.g., paper tape, etc.), a magnetic storage medium (e.g., a flexible disk, a hard disk, a flash memory, etc.), an optical storage medium (e.g., a CD-ROM, etc.), a magneto-optical storage medium (e.g., an MO, etc.), and the like.
Accordingly, the present invention also discloses a non-volatile storage medium having stored therein a data processing program for executing any one of the above-described embodiments of the method of the present invention.
In addition, the steps of the method of the present invention can be implemented by hardware, for example, logic gates, switches, Application Specific Integrated Circuits (ASICs), programmable logic controllers, embedded microcontrollers, and the like, in addition to data processing programs. Thus, such an electronic device that can implement the method of the present invention can also constitute the present invention.
In conclusion, the spindle diameter calculating method provided by the invention can accurately calculate the spindle diameter without considering the diameter of a single yarn and the winding displacement density. Through verifying the yarns composed of different types of fibers and thousands of winding and unwinding operations set by different tensions, the spindle diameter calculation method can obtain better diameter calculation results, and the diameter error of the lower cone forming stage is controlled within the range of +/-4 percent [ (calculated diameter-caliper diameter)/caliper diameter ]. Therefore, the data obtained by the spindle diameter calculation method of the present invention can be placed in HMI for real-time monitoring by the operator.
It will be apparent to those skilled in the art that various modifications and variations can be made to the above-described exemplary embodiments of the present invention without departing from the spirit and scope of the invention. Thus, it is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
