Detailed Description

The invention is described in further detail below with reference to the following figures and detailed description:

example 1

As shown in fig. 1, the method for searching the lagging spindle of the spinning frame based on code scanning identification comprises the following steps:

I. at the top of each tube 1 is indicated a code 2, as shown in fig. 2.

The code 2 is, for example, a common two-dimensional code, a bar code, or the like, but may be a code of another standard.

In addition, the coding system may also be constructed by self-coding, which is not limited herein.

In the embodiment, the codes 2 such as the two-dimensional codes are engraved or sprayed on the top of the bobbin 1 in a code engraving or code spraying manner. The top position can be well recognized by devices such as a bar code because no yarn is wound.

In addition, in order to ensure that the coded information on each bobbin 1 can be accurately and reliably identified by devices such as a code scanner, the present embodiment also has an original design that a plurality of codes 2 are marked on the top of the bobbin in a certain circumferential direction.

The number of the codes 2 is, for example, three, four, five or even more, so as to ensure that when the bobbin 1 is on the spindle, no matter which position of the bobbin 1 the code scanner is aligned to, one code information can be obtained, and the reliability is obviously improved.

As for the code carving or code spraying on the top of the bobbin 1, the existing code carving or code spraying equipment can be adopted for manual operation, and the code carving or code spraying can be automatically carried out in a mode of rotating the bobbin 1 through automatic code carving or code spraying equipment.

Since the engraving or spraying process is not an innovative part of the present invention, the present invention is not explained herein.

And II, sequentially scanning the codes of all the bobbins 1 on the spinning machine by using a first code scanner 3, and simultaneously recording the position serial numbers of the spindles 4 corresponding to all the bobbins 1, thereby establishing the relation between the bobbin codes and the spindle positions.

And uploading the collected coding information of the bobbin 1 and the position serial number information of the corresponding spindle 4 to a spinning database.

The following describes a specific process of scanning identification by using the first scanner 3 with reference to fig. 2:

firstly, a first mounting bracket 6 is mounted on a doffing trolley 5 in front of a spinning machine, and the bracket only needs to be a vertical bracket.

Then, the first scanner 3 is fixed (by bolts) to the first mounting bracket 6.

The mounting height of the first code scanner 3 is the same as the height of the index code 2 when each bobbin 1 is on the spindle 4.

Since the doffing trolley 5 moves along the guide rail 14 in sequence during the doffing and inserting process, the first code scanner 3 can move along with the doffing trolley 5 and perform code scanning identification on the codes on each bobbin 1 when the doffing trolley 5 moves.

The sequential movement here is, for example, in a direction in which the headstock start position of the spinning machine points to the headstock end position of the spinning machine.

Meanwhile, the collected codes on each bobbin 1 are sequentially arranged, so that the codes correspond to the position serial numbers of the corresponding spindles 4, and the codes of each bobbin 1 and the position serial numbers of the spindles 4 corresponding to the bobbin are recorded.

In addition, in order to distinguish different spinning machines, a code can be marked at the head start position of each spinning machine, and the code can also adopt, but is not limited to, a two-dimensional code, a bar code or other standard codes.

Before the first code scanner 3 collects the code information of each bobbin, the doffing trolley 5 is moved to the head initial position of the spinning frame, and the code at the head initial position of the spinning frame is scanned firstly so as to identify the number of the spinning frame.

After the number of the spinning frame is identified, the number one code scanner 3 is used for scanning the codes 2 of all the bobbins 1 on the spinning frame in sequence from the head initial position of the spinning frame, and the number of the bobbins 1 and the position serial number of the spindle 4 corresponding to the bobbins 1 are recorded.

In addition, a first storage 7 is further installed on the doffing trolley 5 (fixed through bolts), and the first code scanner 3 transmits the acquired data to the first storage 7 in real time through a signal line.

The first storage 7 uploads the sorted data to a spinning database through a network to serve as a database for searching spindles.

The data arranged here includes information such as the number of each bobbin 1 and the position number of the corresponding spindle 4.

In the embodiment, the device for collecting the coded information of the upper bobbins of the spinning frame is only the first code scanner 3, and the first scanner 3 is mounted on the existing doffing trolley, so that the cost is obviously reduced.

In the moving process of the doffing trolley, the first scanner 3 can identify the codes on the bobbins 1 at the same time, so that special personnel are not needed for collecting operation, the labor force is not increased, the time cost is not increased, and the practicability is high.

And III, as shown in the figure 3, a second mounting bracket 9 is arranged at the last preparation station before winding in the yarn warehouse 8 of the automatic winder, and a second code scanner 10 is arranged on the second mounting bracket 9 (through bolts).

The second mounting bracket 9 is a vertical bracket.

The mounting height of the second code scanner 10 is equal to the height of the marked codes after each bobbin 1 is put in storage, so that the second code scanner 10 can accurately and reliably scan the codes of the bobbins 1 after the bobbins 1 reach the corresponding positions.

The second scanner 10 is aligned with and scans the last preparation station before winding in the yarn magazine 8 of the automatic winder.

In the rotation process of the yarn storehouse 8, when the bobbin 1 reaches the last preparation station before winding, the second code scanner 10 scans the code of the bobbin 1, and simultaneously records the time when the second code scanner 10 scans the bobbin, namely the working time information of the bobbin 1.

Through the mode, the relation between the code information of each bobbin 1 and the working time information of the bobbin 1 is established.

In addition, a second memory 15 is further mounted on the second mounting bracket 9 (through bolts), and data collected by the second code scanner 10 is transmitted to the second memory 15 in real time through a signal line.

The second memory 15 is used for uploading the received data to a spinning database through a network after the received data are arranged, wherein the arranged data comprise the coding information of the bobbin at the last preparation station before winding and the working time information of the bobbin.

A second code scanner 10 is arranged at the position of each yarn bank, and each yarn bank corresponds to one winding spindle.

In the rotating process of the yarn storehouse 8, as long as a bobbin reaches the last preparation station before winding, the second code scanner 10 collects the coded information on the bobbin 1 and records the working time of the bobbin, so that special personnel are not needed for collection operation.

In addition, the collection mode does not increase labor force, time cost and practicability.

And IV, carrying out online quality detection on the yarn on an automatic winder, and when the quality of the yarn is detected to be qualified, winding the qualified yarn on a cone to obtain a final product which leaves the factory.

And when the quality of the yarn is detected to be unqualified, the defective yarn bobbin is removed. Meanwhile, in order to trace back the lagging spindle, the automatic bobbin winder searches the coding information of the bobbin according to the working time of the winding spindle and the working time information of the bobbin.

V, searching the spindle 4 position serial number corresponding to the coded information of the bobbin from the spinning database, and finding out the backward spindle position.

Compared with a spindle-by-spindle searching mode, the method has the advantages of obviously improved searching efficiency and high automatic tracking reliability.

Example 2

The embodiment 2 describes a method for searching the lagging spindles of the spinning frame based on code scanning identification, and the method can refer to the embodiment 1 except for the following technical characteristics which are different from those of the embodiment 1.

In this embodiment 2, the recording or collecting mode of the spindle position information is changed, that is, the position number information of the spindle is collected while the code information of the bobbin 1 is collected, and the specific process is as follows:

the ring plate 13 of the spinning frame corresponding to the position of each spindle 4 is correspondingly marked (for example, by means of pasting) with a bobbin position verification code 11, and each bobbin position verification code 11 corresponds to a spindle 4 position, as shown in fig. 4.

In addition, a position verification scanner 12 is provided on the first mounting bracket 6.

Wherein, the height of the position verification code scanner 12 is the same as that of each bobbin position verification code 11, so that the spindle position can be accurately and reliably recorded in the running process of the position verification code scanner 12 along with the doffing trolley.

The mode can also establish the relation between the positions of the bobbin 1 and the spindle 4, and is also convenient for searching the laggard spindle subsequently.

The bobbin position verification code 11 may be the same as or different from the bobbin 1 described above.

In the embodiment 2, the bobbin position verification code 11 and the position verification code scanner 12 are provided, and each spindle 4 corresponds to one unique bobbin position verification code 11, so that the serial number of each spinning frame does not need to be identified in advance.

In addition, the embodiment of the invention also compares the difference of the coding technology based on code scanning identification and the RFID radio frequency identification technology in the backward spindle searching aspect of the spinning machine, and the following conclusion is obtained through comparison:

the RFID label is not easy to fix, and is easy to fall off and poor in reliability if directly adhered to the surface of a bobbin, and the structure of the bobbin can be changed if the label is embedded into the bobbin, so that the manufacturing cost of the bobbin is too high;

in addition, no matter which of the above RFID tag fixing methods is adopted, the problem of dynamic balance of the bobbin is caused during the high-speed operation of the bobbin, thereby affecting the quality of the yarn wound on the bobbin.

2. The codes (such as two-dimensional codes, bar codes and the like) adopted in the code scanning identification technology are directly marked on the yarn tubes, so the manufacturing cost is low, the codes cannot fall off in the high-speed running process of the yarn tubes, and the yarn tube yarn scanning identification technology has the advantages of high reliability and the like.

In addition, the code marked on the bobbin does not cause dynamic balance problem due to high-speed running of the bobbin.

By the comparison, the code scanning identification technology has stronger practicability compared with the RFID radio frequency identification.

It should be understood, however, that the description herein of specific embodiments is not intended to limit the invention to the particular forms disclosed, but on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention as defined by the appended claims.
