Detailed Description
The invention discloses a weft insertion device, which can realize fixed-length weft insertion, can ensure the stability of weft insertion and can reduce the manufacturing difficulty.
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without making any creative effort, shall fall within the protection scope of the present invention.
The weft storage device comprises a driving device, an unwinding device and a traction device.
Wherein the driving device is used for driving the winding drum 1 to rotate. The unwinding device comprises a winding drum 1, a bobbin shaft and an elastic pushing piece. The winding drum 1 is arranged on the rotating shaft, and the driving device drives the rotating shaft to rotate so as to drive the winding drum 1 to rotate. To facilitate rotation of the shaft, both ends of the shaft may be mounted in bearings 2. The yarn barrel shaft is used for sleeving the weft yarn barrel 3, and the weft yarn barrel 3 can rotate around the yarn barrel shaft. The weft bobbin 3 is wound with a yarn.
The elastic pushing piece pushes the weft bobbin 3 to the yarn winding drum 1, so that the weft bobbin 3 and the yarn winding drum 1 are in pressing contact. Therefore, when the winding drum 1 rotates, the weft bobbin 3 can be driven to rotate through friction force, so that the radial unwinding of the yarn is realized, and the twist of the yarn can be effectively ensured to be unchanged through the radial unwinding.
In addition, the elastic pushing piece has elasticity, so the elastic pushing piece can provide continuous pushing force, the weft yarn barrel 3 is always contacted with the winding drum 1, and the winding drum 1 can continuously drive the weft yarn barrel 3 to rotate.
The winding drum 1 drives the weft bobbin 3 to rotate in a squeezing friction mode, and the surface linear speed of the winding drum 1 is constant, so that the surface linear speed of the weft bobbin 3 is also constant. Since the surface linear velocity of the weft bobbin 3 is constant, a certain length of yarn always withdraws from the weft bobbin 3 in a unit time regardless of the outer diameter of the weft bobbin 3, and thus, fixed-length weft insertion of the weft insertion device is realized.
Compared with the scheme that the rotating speed of the motor is controlled by a sensor in the prior art, the technical scheme that the winding drum 1 is in extrusion contact with the weft yarn barrel 3 to drive the weft yarn barrel 3 to rotate is easy to realize and stable in operation. The invention can realize fixed-length weft insertion, ensure the weft insertion stability and reduce the manufacturing difficulty.
The unwinding device comprises, in addition to the winding drum 1, the bobbin shaft and the elastic push, a rotating arm 4 and a support 5. One end of the rotary arm 4 is rotatably connected to the bracket 5, and the other end of the rotary arm 4 is connected with the yarn bobbin shaft. The thrust of the elastic pushing element is always applied to the pivoted arm 4, i.e. the pivoted arm 4 always has a tendency to rotate, so that the weft bobbin 3 is pushed towards the winding drum 1 and the weft bobbin 3 is brought into pressing contact with the winding drum 1.
It should be noted that the elastic pushing member may be preferably an elastic clip 19.
It is also added that the invention provides for winding a rubber layer on the winding drum 1 in order to increase the friction between the winding drum 1 and the weft bobbin 3.
The invention sets two rotating arms 4, and the two rotating arms 4 are respectively arranged at two ends of the yarn cone shaft. One end of the rotating arm 4 is provided with a lantern ring which is sleeved on the bracket 5. The swivel arm 4 is then hung on the bracket 5 by means of a sleeve ring. When the rotating arm 4 is pushed by the elastic push piece, the rotating arm 4 can rotate around the bracket 5.
In order to facilitate the disassembly and assembly of the weft yarn cylinder 3, the invention limits the detachable connection between the rotating arm 4 and the yarn cylinder shaft. When the weft yarn cylinder 3 needs to be sleeved on the yarn cylinder shaft, the connection between the rotating arm 4 and the yarn cylinder shaft is released. After the weft bobbin 3 is mounted, the rotating arm 4 is reconnected to the bobbin shaft.
In addition to the rotor arm 4 and the support 5, the unwinding device comprises a pressure roller 6, the pressure roller 6 being in contact with the winding drum 1 and the pressure roller 6 rotating with the rotation of the winding drum 1. The press roll 6 is arranged downstream of the winding drum 1. The yarn pushed down from the weft bobbin 3 passes around the winding drum 1 and the pressure roller 6 in this order. The pressure roller 6 has the function of increasing the pressure between the yarn and the winding drum 1 so that the yarn is moved against the winding drum 1, thus ensuring a stable unwinding of the yarn according to a predetermined path. The pressure roller 6 also has the function of guiding the yarn to the drawing device.
The drive means are described next: the drive means comprise a continuously variable transmission 7. The input shaft 8 of the continuously variable transmission 7 is driven by the main machine. The output shaft 11 of the continuously variable transmission 7 is used for driving the winding drum 1 to rotate. The weft insertion device is driven by the main machine, so that the weft insertion device can keep synchronization with the main machine, and the overall coordination of the loom is improved. Before the weft insertion operation, the transmission ratio of the continuously variable transmission 7 is first calculated according to the weaving width of the loom, so that the weft insertion length of the weft insertion device per unit time meets the requirement.
In order to avoid the impact of the main machine on the weft bobbin 3 at the instant of starting or stopping, the output shaft 11 of the continuously variable transmission 7 in the present invention is defined as an elastic output shaft 11. The elastic output shaft 11 has a buffering effect, so that impact on the weft bobbin 3 is avoided, and the strength of yarns is prevented from being influenced.
It should be noted that the elastic output shaft 11 may be a single-stage spring.
The present invention provides a clutch 9 on an input shaft 8 of a continuously variable transmission 7. When the operator changes the weft bobbin 3 and performs the threading, the input shaft 8 is disengaged from the main machine through the clutch 9. In order to operate the clutch 9, a handle 10 may be provided on the clutch 9.
Next, a traction apparatus is described, which specifically includes: nozzle 13, air supply pipe, control valve 14. The gas supply pipe is used to supply compressed gas to the nozzles 13. A control valve 14 is provided on the gas supply pipe to open or close the gas supply pipe. The yarn exiting from the unwinding device passes through the nozzle 13, so that a downward traction is created on the yarn when the nozzle 13 injects compressed gas. The traction means assist the yarn unwinding from the winding drum 1 and ensure that the yarn follows a predetermined path.
The control valve 14 on the gas supply line is controlled by a main machine sensor which is used for sensing the running condition of the main machine. After the main engine is turned on, the control valve 14 is opened, and the nozzle 13 starts to inject the compressed gas. After the main machine stops, the control valve 14 is closed, and the nozzle 13 stops injecting the compressed gas. The opening and closing of the control valve 14 are synchronous with the main machine, so that the integral coordinated operation of the weaving machine is ensured, and the waste of compressed gas can be avoided.
It should be noted that the host sensor can sense the operation condition of the motor by sensing whether the host power supply is turned on or not.
In order to further ensure the coordinated operation of the main machine and the weft insertion device, the traction device also comprises a photoelectric sensor 12, the yarn passes through the photoelectric sensor 12, and the photoelectric sensor 12 is in communication connection with the main machine. In the case of a stoppage of the main machine, if a yarn passes through the photoelectric sensor 12, the photoelectric sensor 12 sends a yarn signal to the main machine indicating that the weft insertion device is ready to be activated. If no yarn passes through the photoelectric sensor 12, indicating that the weft insertion device is not ready, it cannot be activated.
Under the condition that the main machine is in operation, if the photoelectric sensor 12 detects that no yarn passes through the photoelectric sensor 12, the photoelectric sensor 12 sends a no-yarn signal to the main machine, and the main machine stops to avoid mixing of work and influence on product quality.
The weft insertion device comprises an unwinding device, a driving device and a traction device, and also comprises a weft storage device and a guiding device. The drawing device introduces the yarn into the storage box 15 and the guiding device guides the yarn out of the storage box 15.
The storage box 15 is arc-shaped in cross section to facilitate the movement of the yarn in the storage box 15 to prevent the yarn from being caught in the storage box 15. The weft storage box 15 can be hemispherical, semi-ellipsoidal or semi-cylindrical.
In order to further ensure smooth slippage of the yarns, the weft storage material is preferably stainless steel.
The guiding device comprises a yarn guiding ring 16, a yarn guiding wheel 17 and a tension clamp 18 which are arranged in sequence. A guide ring 16 is arranged at the output end of the storage box 15. The yarn guide wheel 17 is embedded with a bearing, and the yarn guide wheel 17 can rotate freely, so that the friction to yarns is reduced. The yarn guide wheel 17 has a groove around which the yarn passes.
The weft insertion device of the invention has the following use process: the gear ratio of the continuously variable transmission 7 is first calculated from the weaving width so that the continuously variable transmission 7 has a desired gear ratio. When the main machine is stopped, the worker unscrews the clutch 9 through the handle 10, so that the winding drum 1 can rotate freely. Then, a vehicle stop worker sleeves the weft yarn cylinder 3 on the yarn cylinder shaft, and the drawn yarns sequentially bypass the yarn winding drum 1 and the pressing roller 6. The winding drum 1 is rotated to withdraw the yarn from the winding drum 1, after which the yarn is passed successively through a photodetector and a nozzle 13. The winding drum 1 is rotated again, the yarn is led out from the weft storage box 15 to the yarn guide ring 16, passes through the yarn guide ring 16, continues to the yarn guide wheel 17, continues to be led through the tension clamp 18, then passes through the weft yarn detector of the loom, the weft selection finger of the weft selector and the yarn hooking plate, and finally is pressed below the barbed shaft. The yarn drum is rotated continuously by the yarn stop worker, so that the yarn of about 30 centimeters is pre-stored in the weft storage box, then the clutch 9 is reset by operating the handle 10, and finally the main machine is started.
After the main machine is started, the main machine drives the yarn winding drum 1 to rotate through the continuously variable transmission 7, the yarn winding drum 1 can drive the weft yarn barrel 3 to rotate through friction force when rotating, and then the yarn can be radially unwound from the weft yarn barrel 3. Under the traction of the nozzle 13, the yarn is pressed in turn through the winding drum 1 and the pressure roller 6. The yarn then passes out of the nozzle 13 and enters the storage box 15, and then is drawn by the gripper head under the guiding action of the yarn guide ring 16, the yarn guide wheel 17 and the tension clamp 18 to be woven into the cloth surface.
