Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
Referring to fig. 1 to 2, in one embodiment of the present invention, a doffing device is provided, which includes a yarn inserting bar bearing frame 100, a plurality of yarn inserting bars 200 arranged at intervals, and a doffing mechanism 300.
The yarn inserting bar carrier 100 is mainly used for carrying yarn inserting bars 200, and the yarn inserting bar carrier 100 is provided with a first connecting end and a second connecting end which are opposite. It will be appreciated that the number of the carrier 100 may be as many as desired, with a certain number of the insert carriers 200 being disposed on each insert carrier 100. Further, the yarn inserting rods 200 are uniformly arranged on the yarn inserting rod bearing frame 100.
In one embodiment, the carrier 100 may be a free-moving frame that can be moved into position to facilitate doffing by the doffer mechanism 300.
Referring to fig. 1 in combination with fig. 3, the yarn inserting bar 200 is mainly used for carrying a yarn drum 700, and a plurality of yarn inserting bars 200 are mounted on the yarn inserting bar carrier 100 at intervals. The number of the yarn cylinders 700 corresponds to the number of the yarn inserting rods 200, and can be set according to actual doffing requirements.
In one embodiment, the yarn inserting bar 200 has a connecting end connected to the yarn inserting bar carrier 100 and a yarn dropping end opposite to the connecting end, and the yarn dropping end is provided with a blocking body 210 for preventing the yarn bobbin from falling off accidentally. The blocking body 210 can prevent the bobbin mounted on the yarn inserting rod from falling off due to the shaking of the doffing device, that is, the bobbin 700 falls off before entering a designated doffing area, and if the bobbin falls into other areas, the bobbin is easily damaged.
In one embodiment, the blocking body 210 is a blocking ball, and the spherical blocking body 210 is more beneficial to prevent the bobbin 700 from falling off accidentally. Further, the diameter of the blocking ball is 10mm-14 mm. It will be appreciated that the blocking body 700 may also not be limited to a blocking ball, for example, the blocking body 700 may be a blocking ring with a hollow interior.
The doffing mechanism 300 is mainly used for separating the bobbin 700 from the yarn inserting rod 200 to complete doffing. The doffing mechanism 300 is located on one side of the yarn inserting bar bearing frame 100, the doffing mechanism 300 comprises a doffing bar fixing frame 310, a connecting bar 320 and a doffing bar 330, the connecting bar 320 is provided with a first end and a second end, the first end of the connecting bar 320 is slidably connected with the doffing bar fixing frame 310, and the second end of the connecting bar 320 is detachably connected with the doffing bar 330. That is, during the doffing process, the connecting rod 320 drives the doffing rod 330 to move relative to the doffing rod fixing frame 310, so as to peel the bobbin 700 on the yarn inserting rod 200 from the yarn inserting rod 200, thereby completing the doffing process.

During the actual doffing process, the bobbin 700 is horizontally inserted on the yarn inserting rod 200, and the advantage that the extending direction of the yarn inserting rod 200 is perpendicular to the extending direction of the yarn inserting rod 330 is that: when the yarn dropping rod 330 is pushed, the moving direction of the yarn inserting rod 200 is consistent with the inserting direction of the yarn barrel 700, so that the yarn barrel 700 is pushed down conveniently. In addition, the length of the yarn dropping rod 330 is larger than the distance between the two farthest yarn inserting rods 200, so that the length of the yarn dropping rod 330 is enough to cover all bobbins on the yarn inserting rods 200, and the bobbins 700 can be pushed down at one time.
In one embodiment, the doffing mechanism 300 further comprises a doffing rod driving member 350 for driving the connecting rod 320 to slide, and the doffing rod driving member 350 is mounted on the doffing rod fixing frame 310. Further, the doffing rod driving member 350 is a second driving motor, which can always keep constant thrust, so as to avoid the effect of doffing being affected by uneven force application when the doffing rod 330 is pushed manually. Further, the number of the second driving motors is two, and the second driving motors are uniformly installed on the doffing rod fixing frame so as to improve the stress uniformity of the doffing rod 330, so that the doffing rod 330 smoothly doffs, and the yarn bobbin 700 is not damaged.
in one embodiment, the extending direction of the doffing rod 330 is perpendicular to the force application direction of the doffing rod driving member 350, so as to further improve the force bearing stability of the doffing rod 330 in the horizontal direction, thereby enabling the doffing rod 330 to more smoothly doff, and enabling the bobbin 700 to intensively fall into a fixed area while not causing damage to the bobbin 700, so as to facilitate collection.

In one embodiment, the power for the movable carrier 100 may be provided by a first drive motor, and in particular, the movable carrier 100 may be moved along a first runner and a second runner by a chain connected to the first drive motor.
Wherein the detection mechanism is mainly used for detecting whether the carrier 100 of the yarn inserting bar enters the doffing area 10. If the carrier 100 with the yarn packages 700 thereon enters the doffing zone 10, the detection means located in the doffing zone 10 can detect the carrier 100 and send an electric signal to the control means to prompt the operator to perform the doffing operation. Further, the detection mechanism is an infrared detector, specifically, the emitting end of the infrared detector is arranged at the bottom of the doffing area 10, the receiving end of the infrared detector is arranged at the top of the doffing area 10, and whether the yarn inserting rod bearing frame 100 enters the doffing area is sensed through the strength change of the infrared signal.
The control mechanism is mainly used for controlling the doffing rod driving part 350 to execute a driving task by receiving an electric signal sent by the detection mechanism, namely, the driving doffing rod driving part 350 can push the connecting rod 320 to slide so as to drive the doffing rod 330 to contact with the yarn barrel 700, so that the yarn barrel 700 is separated from the yarn inserting rod 200, and automatic doffing is realized.
Specifically, when the control mechanism receives the electric signal sent by the detection mechanism, the control mechanism will control the first driving motor to stop working and control the second driving motor to start working, at this time, the yarn inserting bar bearing frame 100 does not move any more, and the doffing bar 330 starts to doff the yarn bobbin 700 in the doffing area 10. After the doffing is completed, the doffing rod 330 is reset under the control of the second driving motor, the first driving motor is turned on again, at this time, the yarn inserting rod bearing frame 100 continues to move along the chute in the advancing direction, and a cycle is completed when the next yarn inserting rod bearing frame 100 to be doffed enters the doffing area 10.
In one embodiment, the control mechanism is a programmable logic controller, and the programmable logic controller is communicated with the first driving motor and the second driving motor respectively through electromagnetic valves, that is, the programmable logic controller controls the on and off of the electromagnetic valves to realize the operation and the stop of the first driving motor and the second driving motor.
In one embodiment, the doffing device further comprises a doffing pool 500 for receiving the bobbin dropped from the yarn inserting rod, and a conveying mechanism (not shown in the figure) for receiving and conveying the bobbin is installed in the doffing pool 500.
