Background
The spinning line generally includes a bale plucker for opening and opening cotton, a carding machine for carding and drafting the opened and cleaned cotton into cotton slivers regularly arranged in a sliver can, a drawing frame (multiple drawing frames may be arranged as required) for drawing and combining the cotton slivers, and a spinning frame for twisting and spinning uniform yarns with certain number (count) and certain strength. In the whole spinning process, a sliver can (or sliver can) is used as a storage container of slivers (or fiber slivers) in a large amount regardless of a ring spinning process, an eddy spinning process or a rotor spinning process. Taking the rotor spinning process as an example, it usually consists of a bale plucker, a carding machine, a first drawing frame, a second drawing frame and a rotor spinning machine, the cans are transported between the devices, and the joining and return to the empty cans are performed by a barrier. According to the requirement, when coarse yarn and waste yarn with low quality requirement are spun, one-pass drawing or direct sliver feeding can be adopted, and at the moment, only one-pass drawing frame is needed to be arranged or no drawing frame is needed to be arranged.
In a traditional spinning production line, the carrying of a sliver can, the joint of a sliver and the feeding of the sliver are usually manually transferred by a vehicle stop worker, and the connection of all processes is realized. On one hand, the weight of the sliver can added with the loaded sliver is generally over 50kg, even can reach 80kg, and the labor intensity of workers is increased. On the other hand, the spinning workshop has high noise, heavy dust and high temperature, and is not beneficial to the health of workers; with the increase of the labor cost, the production cost of the spinning mill is increased. Therefore, automated barrel transport and sliver delivery become one direction for spinning mill automation and intelligence.
Currently, the prior art also provides technical solutions for transporting through an AGV (shuttle) vehicle to reduce the workload of workers. Taking chinese patent application 201910520791.3 as an example, there is disclosed a can transporting vehicle which travels in a factory provided with a pre-process machine for performing a pre-process treatment on a fiber bundle and a post-process machine for performing a post-process treatment on the fiber bundle having been subjected to the pre-process treatment, and transports a can for accommodating the fiber bundle between the pre-process machine and the post-process machine, the can transporting vehicle comprising: a traveling unit that travels in a factory to transport a can; a map storage unit that stores a plant map indicating installation positions of devices in a plant including installation positions of a pre-process machine and a post-process machine; a travel route determination unit that determines a travel route for going from the preceding process machine to the succeeding process machine or a travel route for going from the succeeding process machine to the preceding process machine, based on the factory map; and a travel control unit that transports the can between the pre-process machine and the post-process machine by autonomously traveling the travel unit based on the determined travel route. However, the barrel transporting vehicle is only responsible for transporting the barrel, and does not relate to automatic sliver conveying (feeding), and still needs manual processing of the joint of the sliver, such as conveying the sliver on the barrel to a sliver guider of the device to realize sliver feeding.
In summary, how to provide a spinning device with can carrying and can sliver automatic feeding and conveying functions is a technical problem which needs to be solved urgently at present.

When the cotton sliver head enters the front end of the sliver guider, the cotton sliver limiting structure is released from fixing the cotton sliver head, and the cotton sliver is conveyed to the carding mechanism under the rotation of the feeding roller.
The sliver self-transmission mechanism and the sliver transport mechanism are described in detail by taking a rotor spinning machine as an example. Referring to fig. 1, the spinning apparatus 100 includes a housing 110 provided with an opening chamber, and a carding mechanism includes an opening roller 120 installed in the opening chamber. The shell 110 is provided with a cotton sliver feeding mechanism 130 and a fiber conveying channel 140 which are respectively communicated with the carding cavity.

Then, the controller controls the male buckle to move towards the female buckle (at this time, a driving motor or a driving cylinder is arranged corresponding to the male buckle and connected with the controller and receives the control of the controller) or controls the female buckle to move towards the male buckle (at this time, a driving motor or a driving cylinder is arranged corresponding to the female buckle and connected with the controller and receives the control of the controller), and the male buckle is inserted into the female buckle to complete the clamping under the driving of the driving motor or the driving cylinder.
When the outer circulation traction structure is required to be separated from the inner circulation traction structure, the controller correspondingly controls the male buckle to move towards the direction far away from the female buckle, or the controller controls the female buckle to move towards the direction far away from the male buckle (at this moment, the movement direction of the driving motor or the driving air cylinder is opposite to the movement direction of the driving motor or the driving air cylinder when the outer circulation traction structure is connected with the inner circulation traction structure).
After the joint structure 195 connects the outer circulation traction structure 180 and the inner circulation traction structure 194, the outer circulation traction structure 180 and the inner circulation traction structure 194 form a closed loop of a cotton sliver conveying chain or belt. The driving wheel in the guide wheel is controlled to rotate to drive the driven wheel to rotate, and the cotton sliver moves towards the direction of the feeding roller 132 under the action of the cotton sliver transmission chain or the transmission belt.

When the sliver head 301 enters the front end of the sliver guide 131, the fixation of the sliver limiting structure to the sliver head 301 is released, and the sliver is conveyed to the carding mechanism 120 under the rotation of the feeding roller 132.
In one embodiment of this embodiment, the tampon stopping structure is preferably a grip structure. Specifically, an electrically controlled clamping structure can be adopted, namely, the clamping and the loosening of the clamp are controlled in an electric driving mode, and at the moment, the electric driving structure of the clamp is connected with the controller and receives the control of the controller; the clamping structure can also adopt a non-electric control mode, namely, the clamping and the loosening of the clamp are controlled in a non-electric mode.

And a position detection structure is arranged corresponding to the clamp, the position information of the clamp is obtained through the position detection structure, whether the clamp reaches the front end of the strip guide device or not is judged, and a clamping release instruction is sent out when the clamp reaches the front end of the strip guide device.
And according to the clamping releasing instruction, controlling the clamping releasing structure to drive the clamp to release so as to release the fixation of the cotton sliver head, and conveying the cotton sliver to the carding mechanism under the rotation of the feeding roller.
Preferably, the position detecting structure may include a camera and an image recognition device, and a detectable mark, such as a special surface color or a special surface texture, or a detectable photoelectric element, is provided at the front end of the bar guider. The image data of the channel of the sliver guide is collected through the camera and sent to the image recognition device, when the sliver reaches the front end of the sliver guide, the detectable mark is covered, and at the moment, no detectable mark exists in the collected image data, so that the clamp can be judged to reach the front end of the sliver guide, and a clamping releasing instruction is sent. And according to the clamping releasing instruction, the clamping releasing structure drives the clamp to release, and the clamp is released to limit (fix) the cotton sliver head.
When a non-electric control clamping structure is adopted, preferably, the clamping structure comprises a clamp movably arranged on the internal circulation traction structure, when the clamp reaches the front end of the sliver guide, the clamp is pushed open under the action of the feeding roller and/or the sliver guide to release the fixation of the sliver head, and the sliver is conveyed to the carding mechanism under the rotation of the feeding roller.
Preferably, after the ejected clamp is separated from the internal circulation traction structure, the ejected clamp falls into a recovery groove arranged at the front end of the strip guide channel under the action of gravity to be recovered.
In another embodiment of this embodiment, the tampon limiting structure can further adopt a movable limiting block for limiting and releasing limiting.
Specifically, the cotton sliver limiting structure may include a limiting groove disposed on the internal circulation traction structure, a telescopic block is disposed corresponding to the limiting groove, and the telescopic block is pressed to enter the limiting groove so as to fix the cotton sliver head in the limiting groove; the front end of the sliver guide is provided with a bulge matched with the limiting groove, when the limiting groove enters the front end of the sliver guide, the bulge enters the limiting groove and drives the telescopic block to move towards the outside of the limiting groove, the limiting groove releases the fixation of the sliver head, and the sliver is conveyed to the carding mechanism under the rotation of the feeding roller.
In this embodiment, preferably, the spinning apparatus may further include a sliver detecting structure disposed corresponding to the sliver guide 131, and the sliver detecting structure detects whether a sliver exists in a preset area in the channel of the sliver guide, and issues a bobbin changing instruction when the sliver does not exist.
According to the can changing instruction, the joint structure is controlled to release the connection between the outer circulation traction structure and the inner circulation traction structure, so that the can conveying mechanism can be separated from the cotton sliver self-transmission mechanism, and an empty can is conveyed away through the shifting robot.
In another embodiment of the embodiment, considering that light impurities with light weight, such as short fibers, are closer to the fiber conveying area, the light impurities are easily sucked back to the carding cavity after being accumulated in the stripping area under the action of fiber conveying negative pressure airflow to generate rolling and back suction, and an impurity discharging structure combining free impurity falling and precise impurity suction is further arranged.
Specifically, referring to fig. 6, a gettering port 171 is provided on the impurity peeling surface 170 to perform gettering corresponding to the impurity peeling surface 170. In the embodiment, the impurity stripping surface and the horizontal plane are arranged in an angle of 60-70 degrees and inclined downwards, and an angle of 65 degrees is preferred. When impurities are discharged, an impurity stripping channel which inclines downwards is formed at the lower part of the carding roller through the impurity stripping surface. Under the comprehensive action of the centrifugal force of the carding roller, the air supply supporting force and the self gravity, the impurity stripping channel can comprise an effective fiber area, a turning and back-suction area and a free impurity falling area from top to bottom. The long fibers in the effective fiber area are kept in the carding cavity to participate in yarn formation. The impurities in the turning back suction area are sucked into the impurity suction channel through the impurity suction port and discharged. The impurities in the free impurity falling area fall into the impurity discharging belt freely and are discharged.
For the uppermost effective fiber area, the fiber length of the area is long, the unit volume weight is small, the carding air-supplying supporting force is larger than the centrifugal force and the gravity comprehensive acting force, so that the limited fibers are kept in the carding cavity to participate in yarn formation. For the middle turning back suction area, the area is mainly composed of light impurities, short velvet and other impurities (because the carding air supply holding force, the centrifugal force and the gravity are kept flat, the partial impurities are easy to be sucked back into the carding body, and accidental broken ends are caused). The gettering is mainly used for removing light impurities, short velvet and the like and preventing the light impurities, the short velvet and the like from being reversely absorbed back to the carding cavity after being rolled, so that the gettering negative pressure requirement is not high, and the low energy consumption is ensured. For the lower free impurity falling area, the area is mainly composed of heavy impurities such as cotton neps, cotton seed hulls, short thread ends and the like, the unit volume weight is large, and the carding air supply supporting force is far smaller than the comprehensive acting force of centrifugal force and gravity, so that the heavy impurities and the large impurities freely fall into an impurity discharging belt to be discharged. The scheme is particularly suitable for the regenerated raw materials with more impurity content, heavy impurities, large impurities and the like in the impurities are freely discharged by combing centrifugal force, light impurities, short fibers and the like in the impurities are transferred and removed by impurity absorption, impurity turning and reverse absorption in an impurity discharge area of a combing cavity are eliminated, effective fiber yarn formation is reserved to the maximum extent, accurate impurity removal is realized, high yield is guaranteed, nep broken ends caused by impurity turning and reverse absorption are reduced, and the spinning suitability of the regenerated raw materials is improved.
