Description

Technical Field

[0001] The utility model relates to the technical field of textile equipment, in particular to a tail yarn cleaning device. Background Art

[0002] In the textile production process, full tubes are installed on textile machines. After the full tubes are used, the textile machines will remove the empty tubes and reinstall the full tubes to start new textile operations. However, some unused tail yarns will remain on the empty tubes removed from the textile machines. At this time, in order to recycle the empty tubes, a tail yarn cleaning device is required to clean the remaining tail yarns on the empty tubes.

[0003] The coarse-fine combined conveying system is used to deliver the full bobbins of roving dropped from the roving frame to the full bobbin storage, and then deliver the full bobbins to the roving frame after the spinning frame issues a demand signal. The empty tubes used by the roving frame are returned to the empty tube storage, and then delivered to the roving frame after the roving frame issues a demand signal, for automatic doffing by the roving frame. During this process, the tail yarn remover is mainly used to automatically remove the tail yarn and waste yarn adsorbed on the sticking strip from the used roving tubes of the roving frame, and then directly supply them to the roving frame for automatic spinning through the automatic conveying system.

[0004] The existing method of removing the residual yarn on the roving bobbin is mainly to manually cut the yarn on the roving bobbin with a hook knife and then peel it off layer by layer. This method is not only dangerous but also damages the roving bobbin. Removing the residual yarn in this way is labor-intensive and affects spinning efficiency. Utility Model Content

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show components related to the present invention.

[0024] like Figures 1 to 5 The tail yarn cleaning device shown is used to clean the roving bobbins with residual yarn rotated out of the spinning process, and can also be used as a tail yarn cleaning device alone, including a cabinet 1, a chain transport part 13 is installed on the top of the cabinet 1, and a bobbin is hung on the spindle of the chain transport part 13. The running direction of the chain on the chain transport part 13 is arranged parallel to the ground, a fan part is installed at the bottom of the cabinet 1, a yarn taking device is installed in the middle of the cabinet 1, and a suction nozzle part is installed on the cabinet 1 between the chain transport part 13 and the yarn taking device, and the fan part is connected to the suction nozzle part;

[0025] The yarn taking device comprises a lifting part and a rotating part. The lifting part is provided with a rotating part for driving the rotating part to move up and down. The rotating part is provided with a yarn taking member 2 for driving the yarn taking member 2 to rotate.

[0026] like Figure 3 and 5 As shown, the lifting part includes a lifting motor 3 and a mounting seat 4, a rotating part is installed on the mounting seat 4, a plurality of slide grooves 5 are opened on the panel of the cabinet 1, the mounting seat 4 is installed in the slide groove 5, and the slide groove 5 is opened along the axial direction of the cabinet 1, and a plurality of proximity switches are also installed on the panel of the cabinet 1. A plurality of proximity switches are installed on the path where each rotating part moves up and down. The output end of the lifting motor 3 is connected to the mounting seat 4 through a transmission component to drive the mounting seat 4 to move up and down along the slide groove 5. In addition, the lifting motor 3 is controlled by a sinusoidal frequency converter to drive the yarn taking component 2 to move up and down, and the position of the yarn taking component 2 is determined by the signal output of the proximity switch in conjunction with the PLC.

[0027] like Figure 2 and 4As shown, the rotating part includes a rotating motor 6 and a yarn taking component 2. The output end of the rotating motor 6 is equipped with a yarn taking component 2 to drive the yarn taking component 2 to rotate. A driver is installed on the rotating motor 6. The signal output and input of the driver are used to realize the forward rotation, high speed and low speed of the rotating motor 6. The speed of each rotating motor 6 is independently adjustable, which can realize high-speed yarn clearing, low-speed yarn clearing and yarn suction.

[0028] At the same time, the PLC is also equipped with a pipe-jacking program protection. When the rising process of the rotating part exceeds 15 seconds, the photoelectric chain conveying motor will stop conveying to avoid pipe-jacking.

[0029] like Figure 4 As shown, the suction nozzle part includes a suction nozzle 7, a cylinder 8 and a solenoid valve. The cylinder 8 is equipped with a solenoid valve to control the start or stop of the cylinder 8. The output end of the cylinder 8 is equipped with a suction nozzle 7 to control the extension and retraction of the suction nozzle 7. A brush assembly is installed on one side of the suction nozzle 7, which is not shown in the figure. The brush assembly includes a brush, a cylinder and an air valve. The brush is installed on the cylinder, and the cylinder is also equipped with an air valve. The extension and retraction of the cylinder drives the brush to extend and retract.

[0030] In addition, a yarn detection photoelectric device is installed in the suction nozzle 7. The function of the yarn detection photoelectric device is to detect whether there is yarn in the suction nozzle 7. If no yarn is detected, the suction nozzle 7 will extend to find the yarn end.

[0031] like Figures 2-3 As shown, the fan part includes a fan 10, which is located below the tail yarn cleaning device. It is one of the main driving forces for the entire device to achieve the yarn cleaning action. Its function is to provide suction for the suction nozzle 7. A first pipe 11 is installed at one end of the fan 10, and a second pipe 12 is installed at the other end of the fan 10. The first pipe 11 is connected to the suction nozzle 7 in the suction nozzle part to provide suction to the suction nozzle 7. The outlet end of the second pipe 12 is connected to the collection box to collect the yarn sucked out by the suction nozzle 7. The suction nozzle 7 and the yarn taking member 2 are staggered.

[0032] It also includes an electric control cabinet 9, which is installed on either side of the cabinet body 1. A cooling fan is installed on the top of the electric control cabinet 9. A PLC is installed in the electric control cabinet 9, and the PLC is electrically connected to the fan part, the suction nozzle part, and the yarn taking device.

[0033] The chain transport part 13 includes a detection photoelectric chain conveying motor. When the chain detection photoelectric detects that a chain is coming, the fan and the chain transport motor are started. The function of the detection photoelectric is to detect whether there is a yarn tube on the hanging spindle. If a yarn tube is detected, the lifting motor 3 will drive the yarn taking part 2 to rise and take the tube (when the count is equal to 8, the yarn tube is detected and the positioning is successful).

[0034] The yarn tube of the chain transport part 13 is coaxially arranged with the yarn taking part 2. A tail yarn head cleaning device (not shown in the figure) for cleaning the tail yarn head that falls off at the bottom of the roving tube is installed on the track of the chain transport part 13. The tail yarn head cleaning device includes a suction nozzle fixed on the track of the chain transport part 13. The suction nozzle is connected to the pipe of the fan through a suction pipe. The fan provides suction to the suction nozzle to clean the yarn head that is too long at the bottom of the roving tube to prevent the yarn head from being too long when the yarn tube enters the tail yarn cleaning part, affecting the success rate of the suction port yarn cleaning.

[0035] The electrical control cabinet is a separate enclosure housing the entire machine's control components, including low-voltage electrical equipment, a PLC, a frequency converter, and a driver. A cooling fan is installed on the top of the cabinet to cool the interior. The side panels contain the power switch, reset button, emergency stop button, and tail yarn direct access button. This electrical cabinet, connected to all the control switches and electrical components on the equipment, serves as the control center for the entire machine. Under normal circumstances, the cabinet door should never be opened.

[0036] Working principle:

[0037] When the roving bobbin with residual yarn is rotated down from the spinning frame process, it is transported to the tail yarn cleaning machine through the coarse and fine connection system. When the chain passes through the tail yarn head cleaning device, the excessive yarn head is cleaned. After the chain detection photoelectric detection, the fan 10 is operated, the inspection tube photoelectric detection of the yarn tube is detected, and the travel switch installed on the track of the chain transport part 13 is toggled. The function of the travel switch is to realize the counting function (when the count is equal to 8, the chain conveying motor installed on the track of the chain transport part 13 is stopped, and the PLC counts. After the counting is completed, the lifting motor 3 rises from the initial position (lower limit) to the upper limit and takes the tube. The suction nozzle 7 extends to start finding the head. When the head is found, the shooting sensor senses the yarn and the suction nozzle 7 retracts to the initial position. At this time, the rotating motor 6 rotates at low speed to cooperate with the suction nozzle 7 to clear the yarn. When the shooting sensor detects the yarn on the bobbin, the middle position or lower limit proximity switch has a signal, the rotating motor 6 changes from low speed to high speed to continue clearing the yarn.

[0038] When the beam sensor and the laser sensor cannot detect the yarn at the same time, the lifting motor 3 starts and descends to the brush position, and the rotating motor 6 changes from high speed to zero speed (under normal circumstances, the yarn on the bobbin should be cleaned at this time).

[0039] When the through-beam sensor installed on the suction nozzle 7 cannot detect the yarn, the laser sensor detects the presence of yarn, the rotating motor 6 changes from high speed to low speed, and the suction nozzle 7 extends to restart the head search (up to 3 times, but it should be noted that this number is only the default number set in the program. Theoretically, the number can be set arbitrarily, and more times can affect the cleaning time. The lifting motor 3 returns to the brush position), and the above actions are repeated (in this case, yarn breakage occurs during the yarn cleaning process). When all the yarn taking parts 2 return to the brush position, the rotating motor 6 rotates at high speed, and the suction nozzle 7 and the brush extend at the same time to clean the yarn The suction nozzle 7 and the brush return to the initial position after a certain period of time, the lifting motor 3 rises to place the bobbin, and then descends to the lower limit position. After the rotating parts stop at the lower limit position, the chain continues to run. When it runs to the bobbin screening part, there is a contrast photoelectric (yarn cleaning effect detection device) on one side of the bobbin screening part. The contrast photoelectric screens the bobbin on the chain to see if there are any uncleaned bobbins. If there are, the clean bobbins on the spare chain are exchanged with the uncleaned bobbins through the exchange mechanism. This action continues until the entire chain is cleaned.

[0040] The above description only describes the specific implementation methods of the utility model. Various examples do not limit the essential content of the utility model. Ordinary technicians in the relevant technical field can make modifications or deformations to the specific implementation methods described above after reading the description without departing from the essence and scope of the utility model.
