Description
Technical Field
The utility model relates to a can fiber strip reading device of textile industry belongs to spinning machine technical field.
Background
The can is used in large quantities in spinning mills as a storage container for fiber strands. The fibre sliver coming from the carding machine is laid in a sliver can in a loop and transported to the creel of the draw frame, even directly to the rotor or vortex spinning machine (also called air-jet vortex spinning machine, air spinning machine). The fibre slivers coming from the drawing frame or combing machine are placed in a can in a loop and transported to the creel of the drawing frame or sliver lap combination machine or roving frame or spinning unit of rotor spinning machine or spinning unit of vortex spinning machine (also called air-jet vortex spinning machine, air spinning machine).
Further, as the trend of intelligent factories is getting faster, cans are also beginning to be transported by AGV cars to the facilities of the respective processes.
During the transportation of these cans, once the fiber strips of the can are used up or the fiber strips of the can are broken, the new can needs to be replaced in time. The traditional method is as follows: the state of the fiber strips of the cans is visually observed by depending on the tour among the cans of operators, and once the fiber strips are exhausted or the fiber strips are broken, the operation of the equipment is manually stopped, or new cans are manually replaced in time.
The method for identifying the state of the sliver can fiber strips completely depending on the visual inspection of operators needs a large number of operators to continuously patrol among slivers, so that the labor amount of the operators is increased, and the number of the operators is increased. Under the actual condition that the labor cost is continuously increased, an automatic and intelligent method for identifying the state of the sliver can fiber strips becomes urgent need, the labor amount and the labor cost of operators can be saved, necessary preparation can be made for an intelligent spinning factory, the state of the sliver can fiber strips can be automatically identified, and therefore sliver can replacement and automatic joint can be automatically achieved.
Currently, textile machine manufacturing businesses are striving to find solutions to overcome this drawback. For example, the invention: CN110791841A "spinning pot with display element for displaying fiber material characteristics", proposes a can with light-emitting element, the height of the light-emitting column shows the volume of fiber rod in the can, and the operator is prompted to know the state of fiber rod in the can in time by light-emitting. However, the defects of the invention are that: on one hand, the difficulty of finding the state of the sliver can is reduced and the efficiency is improved only for operators, but the automatic identification of the state of the sliver can cannot be realized, and the state information is sent to the machine equipment; on the other hand, the invention needs to additionally arrange a light-emitting part, a control part and a power supply part in the can, thereby greatly increasing the cost.

Detailed Description
The present invention will be further explained with reference to the drawings and examples.
Example 1.
As shown in FIG. 1, a can 1 containing a sliver 2 is provided with a can sliver information storage part 3. In the sliver production process of carding, drawing and combing machines, the sliver 2 is looped onto the can 1. When the length of the sliver 2 in the can 1 reaches a preset length, the carding machine, the drawing frame or the combing machine starts to change the can, and information of the sliver (in the embodiment, the information refers to the length of the sliver, the number of broken ends, the length of the sliver between the broken ends, and the like) is written into the sliver information storage part 3.
The sliver information storage part 3 is mounted on the side wall of the sliver can and stores information such as the length of the sliver, the number of broken ends, and the length of the sliver between the broken ends.
The sliver information storing part 3 may be installed in the bottom area of the can 1 or the lower end of the tray of the can 1 according to actual production conditions. Preferably, as shown in fig. 1, the sliver information storing part 3 is installed at a side wall of the can 1.
The sliver can sliver reading device 4 comprises a reading unit 5 and a control processing unit 6. The reading unit 5 and the fiber strip information storage component 3 read and write information in a non-contact mode based on an RFIDID communication mode. The reading unit 5 of the sliver reading device 4 reads information such as the length of the sliver, the number of breaks, and the length of the sliver between the breaks from the sliver information storage unit 3. The information of the fiber strip read by the read/write unit 5 is transmitted to the control processing unit 6. Further, the control processing unit 6 calculates the exhaustion time and the breakage time of the sliver in the can 1 based on the feeding speed of the sliver 2 (i.e., the speed at which the sliver 2 is fed to the sliver guide 8, the rotor spinning unit P1, and the spinning unit P2 of the vortex spinning machine) based on the read sliver information (sliver length, number of breakage, and fiber length between breakage). The basic and simple calculation method is as follows:
sliver depletion time = sliver length/sliver feed speed + sliver stop feed time.
Sliver break time = sliver length between breaks/sliver feed speed + sliver stop feed time.
The control processing unit 6 in the sliver can sliver reading device 4 transmits the state information of the sliver 2 to equipment such as a drawing frame, a sliver lap combination machine, a roving frame, a rotor spinning machine, an eddy current spinning machine, an AGV (automatic guided vehicle), a splicer, a doffer and the like according to the calculated sliver exhaustion time or sliver breakage time when the sliver 2 of the sliver 1 is exhausted or broken so as to carry out the next action. Generally, the actions include the AGV changing the sliver can, the splicer splicing action, stopping feeding the fiber sliver and the like.
The communication between the sliver can sliver reading device 4 and the sliver can sliver information storage part 3 is a contactless method, as shown by reading information S in fig. 1, indicating the way of information interaction. In this embodiment, a radio frequency (rfid) -based method is used between the reading device 4 and the storage unit 3. At present, the RFID contactless communication method is widely used in industry, and is a mature and economical solution.
Example 2.
As shown in FIG. 2, can sliver-reading apparatus 4 is mounted to one embodiment of sliver guide 8.
In the drawing frame, for a single-eye drawing frame, usually a maximum of 8 cans 1 are fed to a creel 8; for a double-eye drawing frame, a maximum of 16 cans 1 are usually fed into the creel 8. For the creel of the roving frame, up to 250 cans 1 are fed into the creel 8. As shown, a can sliver reading device 4 is mounted above a can 1 of a sliver guide 8. The sliver reading device 4 reads sliver information of the sliver information storage part 3 in a non-contact manner. And according to the read fiber strip information, calculating and analyzing, and transmitting the fiber strip state information to equipment for the next action. The basic principles and methods of reading and processing the information of the fiber strips are consistent with example 1.
Preferably, the creel 8 can share one or the can sliver reading device 4, so that a great cost saving is possible, especially for the creel of a roving frame.
Preferably, the sliver guide 8 can have a sliver-reading device 4 per can, in particular for drawing frames, a maximum of 8 or 16 cans, so that the sliver state in each can be monitored in real time.
Example 3.
As shown in fig. 3, the can sliver-reading device 4 is installed at a spinning unit P1 of the rotor spinning machine. The sliver 2 of the sliver 1 is fed to a feed roller 9, carded by a carding roller 10, fed to a rotor 11, twisted by the rotor 11 rotating at a high speed to form a yarn, and fed to a yarn guide roller 12 to form a package 13.
The can sliver reading device 4 is installed in the area of the spinning unit P1 near the can 1, communicates with the can sliver information storage part 3, reads the information S, and transmits sliver state information to the rotor spinning machine for the next action by calculation and analysis based on the read sliver information. The basic principles and methods of reading and processing the information of the fiber strips are consistent with example 1.
Example 4.
As shown in fig. 4, the can sliver-reading device 4 is installed at a splicer G1 of the rotor spinning machine, unlike that shown in fig. 3. Preferably, can sliver reading means 4 is located close to can sliver information storage means 3. In this embodiment 4, since the sliver-reading device 4 is installed on the traveling splicer G2, one can sliver-reading device 4 is not necessarily provided for each spinning unit P1. For a rotor spinning machine, 700 spinning units are large, and this solution is clearly capable of significantly reducing costs.
Sliver-sliver reading device 4 is mounted at splicer G1. When the splicer G1 roams to a can 1 of a spinning unit P1, the can sliver reading device 4 communicates with the can sliver information storage part 3, reads the information S, and transmits sliver state information to the splicer G1 through calculation and analysis based on the read sliver information to perform the next operation. The basic principles and methods of reading and processing the information of the fiber strips are consistent with example 1.
Example 5.
As shown in fig. 5, the sliver-reading device 4 is installed at a spinning unit P2 of the vortex spinning. The fiber strip 2 in the sliver can 1 is fed into a drafting system 14, the drafted fiber strip 2 enters a nozzle 15 of high-speed rotating airflow, is twisted into yarn under the action of the high-speed rotating airflow, passes through a yarn guide roller 16, and is wound into a cone yarn 17.
The can sliver reading device 4 is installed in the area of the spinning unit P2 near the can 1, communicates with the can sliver information storage part 3, reads the information S, and transmits sliver state information to the vortex spinning machine for the next action by calculation and analysis based on the read sliver information. The basic principles and methods of reading and processing the information of the fiber strips are consistent with example 1.
Example 6.
As shown in fig. 6, the can sliver-reading device 4 is installed in a doffer G2 of the vortex spinner, unlike that shown in fig. 5. Preferably, can sliver reading means 4 is located close to can sliver information storage means 3. In this embodiment 6, since the sliver-reading device 4 is mounted on the traveling doffer G2, each spinning unit P2 is not necessarily provided with one can sliver-reading device 4. For the vortex spinning machine, the spinning unit is 200 units, and the solution is definitely capable of reducing the cost remarkably.
The sliver can sliver reading device 4 is installed at the doffer G2. When the doffer G2 patrols to the can 1 of a spinning unit P2, the can sliver reading device 4 communicates with the can sliver information storage part 3, reads the information S, and transmits sliver state information to the doffer G2 through calculation and analysis according to the read sliver information to perform the next action. The basic principles and methods of reading and processing the information of the fiber strips are consistent with example 1.
Example 7.
As shown in fig. 6, can sliver reading device 4 is mounted on AGV car G3. When the AGV car G3 is in the process of transporting the can 1, the information of the sliver 2 is read from the can fiber information storage part 3.
The sliver can sliver reading device 4 is communicated with the sliver can sliver information storage part 3, reads the information S, and transmits sliver state information to the AGV through calculation and analysis according to the read sliver information to perform the next action. The basic principles and methods of reading and processing the information of the fiber strips are consistent with example 1.
For example 7, the AGV car G3 navigates between facilities while carrying a can 1. During this process, AGV car G3 reads sliver 1, sliver 2 information. Only the sliver can sliver information reading device 4 needs to be mounted on the AGV car G3, thereby saving the cost of installation at each spinning unit (P1, P2) or sliver guide 8, which is a very economical solution.
Various modifications, additions and substitutions for the specific embodiments described herein will occur to those skilled in the art without departing from the scope of the invention as defined by the accompanying claims.
