Description

Technical Field

[0001] The utility model relates to the technical field of chemical fibers, in particular to a doffing conveying line with a yarn control device. Background Art

[0002] The existing doffing conveyor line is as shown in the attached manual. Figure 5 As shown, the horizontal conveyor chain comprises a horizontal conveyor chain 11 and bobbin sockets 12 evenly distributed and fixed on the horizontal conveyor chain. A bobbin 90 wound with yarn 91 is inserted into the bobbin socket 12 and conveyed to the left by the horizontal conveyor chain. The bobbin is lifted to a certain height by a rear yarn lifting plate 202 at the rear side of the horizontal conveyor chain and allowed to fall onto the discharge lifting conveyor belt. A baffle is provided at the left end of the horizontal conveyor chain. However, existing doffing conveyor lines have the following shortcomings: first, the rear yarn lifting plate cannot completely knock down all bobbins, and some bobbins can continue to move leftward with the horizontal conveyor chain; second, bobbins that are not knocked down can easily cause the entire conveyor line to become stuck due to the blocking effect of the baffle. Utility Model Content

[0003] The purpose of the utility model is to provide a yarn doffing conveyor line with a yarn control device. Through the cooperation of the yarn control device and the yarn lifting device, the yarn tubes can be effectively pushed onto the discharge lifting conveyor belt, ensuring the smooth discharge of the yarn tubes and solving the problem that the conveyor line is easily stuck.

[0004] The above technical objectives of the present invention are achieved through the following technical solutions:

[0005] A doffing conveyor line with a yarn control device comprises a horizontal conveyor chain arranged at the lower end of a spinning frame, a plurality of bobbin inserting seats uniformly distributed along the horizontal conveyor chain are fixed on the horizontal conveyor chain, and bobbins wound with yarn can be inserted into the bobbin inserting seats;

[0006] A discharge lifting conveyor belt is provided at the front side of the left end of the horizontal conveyor chain, and the horizontal conveyor chain and the discharge lifting conveyor belt are arranged on the conveyor frame; a yarn lifting device and a yarn control device are provided at one end of the horizontal conveyor chain close to the discharge lifting conveyor belt;

[0007] The yarn control device includes a yarn control base plate and a yarn control strip fixed on the yarn control base plate and formed by bending a steel wire;

[0008] The yarn lifting device includes a front yarn lifting plate and a rear yarn lifting plate arranged in front and back. The front yarn lifting plate and the rear yarn lifting plate are respectively arranged on both sides of the bobbin socket and located above the horizontal conveying chain. The front yarn lifting plate and the rear yarn lifting plate are fixed on the conveying frame.

[0009] The spinning frame winds the yarn on the bobbin, and then the spinning frame inserts the bobbin wound with the yarn into the corresponding multiple bobbin sockets on the water book conveyor chain in an orderly manner. The horizontal conveyor chain drives the bobbin with the yarn to the left through the bobbin socket. When the bobbin moves to the front yarn lifting plate and the rear yarn lifting plate, the front yarn lifting plate and the rear yarn lifting plate contact with the outer layer of the wound yarn to move the entire bobbin upward. At the same time, the upper end of the bobbin is pushed forward by the action of the yarn control device and pushed onto the discharge lifting conveyor belt, and finally output through the discharge lifting conveyor belt.

[0010] The utility model is further configured as follows: the yarn control strip includes an integrally bent inclined portion, a left connecting portion and a right connecting portion, the left connecting portion and the right connecting portion are fixed on the yarn control base plate, the left end of the inclined portion is located on the front side of the yarn tube socket seat below it, and the right end of the inclined portion is located on the rear side of the yarn tube socket seat below it.

[0011] With the above technical solution, the bobbin passing through the inclined portion can be gradually pushed forward by the inclined portion, thereby pushing the bobbin onto the discharge lifting conveyor belt, thereby ensuring smooth discharge of the bobbin.

[0012] The utility model is further configured as follows: the front yarn raising plate comprises a front inclined yarn guiding section arranged with the left side higher and the right side lower and a front horizontal section arranged at the left end of the front inclined yarn guiding section;

[0013] The rear yarn raising plate comprises a rear inclined yarn guiding section which is arranged with the left side higher and the right side lower and a rear horizontal section which is arranged at the left end of the rear inclined yarn guiding section. The rear horizontal section is higher than the front horizontal section.

[0014] Through the above technical solution, the bottom of the yarn on the bobbin is conical, and the bobbin conveyed by the horizontal conveyor chain gradually lifts the entire bobbin upward through the front inclined yarn guide section and the rear inclined yarn guide section, thereby separating the bobbin from the bobbin socket.

[0015] The utility model is further configured as follows: a proximity sensor and a high-pressure air blow pipe are fixed on the yarn control substrate, the high-pressure air blow pipe is connected to a high-pressure air source through a solenoid valve, and the proximity sensor and the solenoid valve are electrically connected to the controller.

[0016] If the yarn tube is not pushed down by the yarn control device, the proximity sensor detects that a yarn tube has passed and transmits the signal to the controller. The controller uses the solenoid valve to blow out high-pressure gas from the high-pressure blowing pipe, thereby dropping the yarn tube onto the discharge lifting conveyor belt.

[0017] Or when the yarn controller is under maintenance, in order to continue production without stopping the machine, the proximity sensor and high-pressure air blow pipe can be used as a backup solution to blow off the yarn tube.

[0018] The utility model is further configured as follows: a baffle plate with a lower left and higher right setting is provided on the right side of the bottom of the discharging lifting conveyor belt, and a flexible rubber plate is fixed to one end of the baffle plate close to the discharging lifting conveyor belt, and the left end of the flexible rubber plate is bent to the upper left and abuts against the outer wall of the discharging lifting conveyor belt.

[0019] The deformation ability of the flexible rubber plate can facilitate the passage of the baffle on the discharge lifting conveyor belt. The flexible rubber plate can temporarily support the yarn tube pushed down by the yarn control device to prevent it from falling off the lifting conveyor belt.

[0020] The outstanding effects of the utility model are:

[0021] Compared with the existing technology, the cooperation of the yarn control device and the yarn lifting device can effectively ensure that the yarn tubes are pushed onto the discharge lifting conveyor belt, ensure the smooth discharge of the yarn tubes, and solve the problem of easy jamming of the conveyor line.

[0034] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0035] The following references Figures 1 to 4 The utility model is described as follows:

[0036] A doffing conveyor line with a yarn control device includes a horizontal conveyor chain 11 arranged at the lower end of a spinning frame 10, a plurality of bobbin sockets 12 linearly and evenly distributed along the horizontal conveyor chain 11 are fixed to the horizontal conveyor chain 11, and bobbins 90 wound with yarns 91 can be inserted into the bobbin sockets 12;

[0037] A discharge lifting conveyor belt 13 is provided at the front left end of the horizontal conveying chain 11. The horizontal conveying chain 11 and the discharge lifting conveyor belt 13 are arranged on a conveying frame; a yarn lifting device 20 and a yarn control device 30 are provided at one end of the horizontal conveying chain 11 close to the discharge lifting conveyor belt 13;

[0038] The yarn control device 30 includes a yarn control base plate 301 and a yarn control strip 302 fixed on the yarn control base plate 301 and formed by bending a steel wire;

[0039] The yarn lifting device 20 includes a front yarn lifting plate 201 and a rear yarn lifting plate 202 arranged in front and back. The front yarn lifting plate 201 and the rear yarn lifting plate 202 are respectively arranged on both sides of the yarn tube socket seat 12 and are located above the horizontal conveying chain 11. The front yarn lifting plate 201 and the rear yarn lifting plate 202 are fixed on the conveying frame.

[0040] The spinning frame winds the yarn on the bobbin, and then the spinning frame inserts the bobbin wound with the yarn into the corresponding multiple bobbin sockets on the water book conveyor chain in an orderly manner. The horizontal conveyor chain drives the bobbin with the yarn to the left through the bobbin socket. When the bobbin moves to the front yarn lifting plate 201 and the rear yarn lifting plate 202, the front yarn lifting plate 201 and the rear yarn lifting plate 202 contact with the outer layer of the wound yarn, thereby pushing the entire bobbin upward. At the same time, the upper end of the bobbin is pushed forward by the action of the yarn control device, and pushed onto the discharge lifting conveyor belt, and finally output through the discharge lifting conveyor belt.

[0041] The control yarn strip 302 includes an integrally bent inclined portion 3021, a left connecting portion 3022 and a right connecting portion 3023, the left connecting portion 3022 and the right connecting portion 3023 being fixed on the control yarn base plate 301, the left end of the inclined portion 3021 being located in front of the yarn tube socket seat 12 below it, and the right end of the inclined portion 3021 being located in the rear of the yarn tube socket seat 12 below it.

[0042] With the above technical solution, the bobbin passing through the inclined portion can be gradually pushed forward by the inclined portion, thereby pushing the bobbin onto the discharge lifting conveyor belt, thereby ensuring smooth discharge of the bobbin.

[0043] The front yarn raising plate 201 includes a front inclined yarn guiding section 2011 which is arranged obliquely with the left side higher and the right side lower, and a front horizontal section 2012 which is arranged at the left end of the front inclined yarn guiding section 2011;

[0044] The rear yarn raising plate 202 includes a rear inclined yarn guiding section 2021 that is tilted and arranged with a left side higher and a right side lower, and a rear horizontal section 2022 that is arranged at the left end of the rear inclined yarn guiding section 2021. The rear horizontal section 2022 is higher than the front horizontal section 2012.

[0045] Through the above technical solution, the bottom of the yarn on the bobbin is conical, and the bobbin conveyed by the horizontal conveyor chain gradually lifts the entire bobbin upward through the front inclined yarn guide section and the rear inclined yarn guide section, thereby separating the bobbin from the bobbin socket.

[0046] A proximity sensor 303 and a high-pressure air blowing pipe 304 are fixed on the royal yarn substrate 301. The high-pressure air blowing pipe 304 is connected to a high-pressure gas source through a solenoid valve. The proximity sensor and the solenoid valve are both electrically connected to the controller.

[0047] If the yarn tube is not pushed down by the yarn control device, the proximity sensor detects that a yarn tube has passed and transmits the signal to the controller. The controller uses the solenoid valve to blow out high-pressure gas from the high-pressure blowing pipe, thereby dropping the yarn tube onto the discharge lifting conveyor belt.

[0048] Or when the yarn control device is maintained, in order to continue production without stopping the machine, the proximity sensor 303 and the high-pressure air blowing pipe 304 can be used as a backup solution to blow off the yarn tube.

[0049] A baffle plate 14 is provided on the right side of the bottom of the discharging lifting conveyor belt 13, and a flexible rubber plate 15 is fixed to one end of the baffle plate 14 close to the discharging lifting conveyor belt 13. The left end of the flexible rubber plate 15 is bent to the upper left and abuts against the outer wall of the discharging lifting conveyor belt 13.

[0050] The deformation ability of the flexible rubber plate can facilitate the passage of the baffle on the discharge lifting conveyor belt. The flexible rubber plate can temporarily support the yarn tube pushed down by the yarn control device to prevent it from falling off the lifting conveyor belt.

[0051] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications based on the above assumptions should also be regarded as within the scope of protection of the present invention.
