The production process of the spinning thread comprises a step of winding and collecting the silk threads output in clusters. Depending on the process of forming the spinning thread, the wire feeder must be continuously running and delivering the thread without interruption. However, the thread winding member for winding the thread has a limited load-bearing capacity, and once the total length of the thread wound around the thread winding member reaches a certain critical value, the thread winding member cannot continuously bear the thread, and the thread is cut at a preset thread cutting position between the thread feeding mechanism and the thread winding member, and then the thread winding member full of the thread is detached from the thread collecting device, and then the thread winding member is replaced with a new thread winding member to continuously bear and collect the thread.

The maximum friction force between the first transmission member and the yarn winding member is preset to be smaller than the external force required for breaking the yarn. Therefore, when the difference between the active winding and take-up linear speed and the silk thread conveying linear speed of the silk winding piece is small, the silk winding piece can be driven by the first transmission piece through acting friction force; if the difference between the active winding and take-up linear velocity of the silk winding piece and the linear velocity of the silk thread is large, the tensile force applied to the silk thread can be increased, the friction force between the silk winding piece and the first transmission piece can not overcome the force of the silk thread reacting on the silk winding piece, and the silk winding piece and the first transmission piece slip to avoid breaking the silk thread.

Detailed Description

The technical solutions in the embodiments of the present invention will be clear and fully described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work all belong to the protection scope of the present invention.

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 herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "or/and" includes any and all combinations of one or more of the associated listed items.

The utility model provides a silk thread collecting device 100 for carrying and coiling and collecting spinning threads. The filament collection apparatus 100 includes a wire feeder 10, a trap mechanism 20, a side push mechanism 30, and a take-up mechanism 40, the functions of which are described first below.

The wire feeder 10 is designed to continuously and uninterruptedly feed a row of threads to the side facing the trap 20/take-up 40, where the row is: the wires are distributed in rows through portions of the wire feeder 10, the instantaneous speed direction of the wires at the instant they leave the wire feeder 10 being the same; the thread collecting device 100 has a preset thread cutting position through which the thread can be cut at a certain time; the filament take-up mechanism 40 is used for taking the filament output by the filament feeding mechanism 10 at the preset filament cutting position, and then winding and collecting the filament.

Obviously, the above-mentioned moment of cutting the yarn is the moment when the yarn winding member 41 for winding the collected yarn in the yarn winding mechanism 40 is fully loaded and the yarn winding cannot be continued. The silk threads are cut off, more silk threads are prevented from being continuously transferred to the silk winding piece 41, and the silk threads collected by the silk winding piece 41 which is in a full-load state can be conveniently communicated with the silk threads collected by the silk winding piece 41 to be detached from the silk thread collecting device 100; the full load of the winding member 41 is removed and a new empty winding member 41 is then mounted on the thread collecting device 100 again, so that the thread can be taken up and collected again.

The purpose of the catching mechanism 20 is to apply an external force to the thread segments 210 to tension the thread segments 210 and to catch at least the thread ends 2101 of the cut thread segments 210 in a predetermined thread cutting position, thereby allowing the thread ends 2101 to wait for a new empty thread winding member 41 to be installed in place in this position, but also allowing the thread ends 2101 to slightly pass over the predetermined thread cutting position, in which case the thread segments 210 in the predetermined thread cutting position are retained in the predetermined thread cutting position to wait for a new empty thread winding member 41 to be installed in place. Once the empty-load wire winding member 41 is in place, the retention mechanism 20 immediately releases the retention constraint on the wire end 2101 or the wire section 210, thereby releasing the wire section 210 toward the empty-load wire winding member 41. Here, the filament section 210 means: the part of the thread passing through the predetermined thread cutting position is cut off, and the part of the thread still connected to the thread feeding mechanism 10 and not taken up by the thread winding member 41, so the thread end 2101 mentioned above is the end of the thread segment 210, and the thread end 2101 should not be understood as the end of the thread wound around the thread winding member 41. In order to more quickly retain the filament end 2101 or the filament segment 210, the action end of the retention mechanism 20 for applying the restraining force to the filament end 2101 is located at the preset filament cutting position.

For convenience, the portion of the filament wound around the filament winding member 41 will be referred to hereinafter as the winding section, and the portion of the filament that has not been taken by the filament winding member 41 and is at the point of contact with the wire feeder 10 to the filament end 2101 will be referred to hereinafter as the section to be wound. Therefore, in the case where the retaining means 20 exerts a tension on the thread piece 210, the thread end 2101 may be retained in the predetermined thread cutting position, or a portion of the thread piece 210 near the thread end 2101 may be retained.

The side pushes away mechanism 30 is used for and treats the winding section contact and drive and treat the winding section activity in order to change its curve shape, the utility model discloses do not inject the specific position that the winding section was treated in the side pushes away mechanism 30 contact and the specific quantity of contact position. In the case that the side pushing mechanism 30 contacts the segment to be wound, if the filament end 2101 or the filament segment 210 is trapped at the preset filament cutting position, the side pushing mechanism 30 moves relative to the filament feeding mechanism 10 and/or the trapping mechanism 20, and the forward bending length of the segment to be wound is increased by pushing the segment to be wound. Here, the thread portion corresponding to the increased straight bending length is the buffered thread portion during the detachment of the fully loaded yarn winding member 41; if the unloaded wire winding member 41 is installed in place, the side pushing mechanism 30 also moves relative to the wire feeding mechanism 10 and/or the retaining mechanism 20, and finally the length of the downbent section to be wound is reduced. By "straight-bending length" is meant the length of a trace that represents a curve, or it is understood that the length of a line after the curve has been straightened into straight segments.

As mentioned above, the yarn winding mechanism 40 includes the yarn winding member 41, and the yarn winding mechanism 40 further includes the yarn pulling driving assembly, the yarn pulling driving assembly includes the yarn pulling driving source, the first transmission member which is connected to the power output end of the yarn pulling driving source in a following manner, and the yarn dragging portion 411 which is mounted to the yarn winding member 41 in a following manner, and has a preset yarn winding center, and the first transmission member is in transmission connection with the yarn winding member 41. Under the driving of the filament drawing driving source, the first transmission member drives the filament winding member 41 to rotate by taking the preset filament winding center as a rotation center, and meanwhile, the filament dragging part 411 rotates synchronously along with the filament winding member 41, and the motion track of the filament dragging part is a closed loop track passing through the preset filament cutting position. If the filament drawing driving source continuously drives the filament winding member 41 through the first transmission member, the filament drawing part 411 can perform a loop-back motion along the closed-loop trajectory to repeatedly pass through or approach the preset filament cutting position. The wire winding member 41 is driven to rotate by the wire drawing driving source through the first transmission member, which for convenience of description can be defined as an active winding movement of the wire winding member 41.

Optionally, the wire winding member 41 is frictionally connected to the first transmission member, when the wire winding member 41 performs the active winding motion, the power output by the wire drawing mechanism is directly transmitted to the wire winding member 41 through the first transmission member, and a power transmission path is formed between the wire winding member 41 and the first transmission member through static friction force. The maximum static friction force between the thread winding member 41 and the first transmission member is preset to be smaller than the minimum external force for snapping the thread; the moving linear speed of the filament dragging part 411 responding to the output power of the filament dragging driving source is set to be not less than the wire feeding linear speed of the wire feeding mechanism 10, that is, when the filament winding member 41 performs the active winding movement, the filament dragging part 411 moves along the preset closed loop track and drives the filament to wind at a linear speed not less than the wire feeding linear speed of the wire feeding mechanism 10, so that the filament dragging amount of the filament dragging part 411 is not less than the wire feeding amount of the wire feeding mechanism 10 in the same time. Therefore, the section to be wound can be tensioned to a certain degree, and the section to be wound is prevented from loosening.

When the difference between the filament winding speed of the filament winding member 41 during the active winding movement and the filament conveying speed (the filament feeding line speed of the filament feeding mechanism 10) is small, the tensile force applied to the segment to be wound is at a low level, and at this time, the filament winding member 41 can be driven by the first transmission member in a friction manner; if the difference between the yarn receiving speed and the yarn conveying speed of the yarn winding member 41 during the active winding movement is large, the section to be wound is subjected to a large tension force, and the friction force between the yarn winding member 41 and the first transmission member cannot overcome the force of the yarn reacting on the yarn winding member 41, so that the yarn winding member 41 and the first transmission member slip, the active winding movement of the yarn winding member 41 can be slowed down, and the possibility that the yarn is broken is finally eliminated.

Therefore, the torque formed by the maximum static friction force on the first transmission member can be used as a preset peak load, and if the actual load/actual torque applied to the first transmission member by the wire drawing driving source through the power output end of the wire drawing driving source is greater than the preset peak load, the wire winding member 41 slips from the first transmission member.

In one embodiment, the wire-pulling driving assembly includes a magnetic transmission member or a magnetizable transmission member, and the wire-winding member 41 can be attracted to the magnetic transmission member or the magnetizable transmission member after magnetization treatment by magnetic attraction. After the wire pulling driving source is started to operate, the wire winding member 41 can rotate synchronously around the center of the wire under the magnetic attraction of the magnetic transmission member or the magnetized and treated magnetizable transmission member. In this embodiment, the lead wire driving assembly may also be configured to have a predetermined peak load, the specific magnitude of which is positively correlated to the magnitude of the magnetic attraction of the magnetic transmission member or the magnetized magnetizable transmission member to the wire winding member 41, the maximum value of the magnetic attraction being predetermined to be smaller than the minimum external force for snapping the wire. When the actual load of the power output end of the wire pulling driving source is greater than the preset peak load, the wire winding member 41 moves relative to the magnetic transmission member or the magnetizable transmission member, so that the wire can be prevented from being pulled apart. It should be noted that the fact that the wire winding member 41 moves synchronously with the magnetic transmission member or the magnetizable transmission member does not mean that the wire winding member 41 contacts the magnetic transmission member or the magnetizable transmission member, and the wire winding member 41 may not contact the magnetic transmission member or the magnetizable transmission member as long as the magnetic attraction force can be generated. Preferably, the magnetic or magnetizable transmission element can be provided as a magnetic powder drive.

In one embodiment, the retention mechanism 20 includes an airflow generating device 21, and the airflow generating device 21 has an airflow channel 211 oriented to the predetermined shredding position. By activating the gas flow generator 21 or increasing the operating power of the gas flow generator 21, the gas is accelerated from the side of the gas flow path 211 relatively close to the wire feeder 10 to the side of the gas flow path 211 relatively far from the wire feeder 10 and passes through the predetermined shredding position. Under the action of the gas flow, the filament section 210 part or the filament end 2101 trapped at the preset filament cutting position is driven by the gas and is tensioned, so that the filament end 2101 can not generate retraction movement and is separated from the preset filament cutting position.

Optionally, the airflow generating device 21 includes a blowing assembly and an air guiding channel, and the air guiding channel has an airflow channel 211 pointing to the preset shredding position. After the blowing assembly is started or the power of the blowing assembly is improved, the blowing assembly accelerates to continuously convey air flow into the air guide channel, and at the moment, the silk thread end 2101 located at the preset shredding position or the part of the to-be-wound section close to the silk thread end 2101 is driven by the air flow to be tensioned. In the actual operation process, the thread end 2101 is allowed to extend into the air guide channel, that is, the thread end 2101 is allowed to cross the preset thread cutting position. When the new yarn winding member 41 is installed in place, the yarn section 210 extending into the air guide channel can be cut short at a preset yarn cutting position, the residual yarn in the air guide channel after cutting is discarded, and the new yarn winding member 41 obtains a new yarn end 2101, so that the next winding is started to wind and take up the yarn.

Optionally, the airflow generating device 21 comprises a negative pressure channel connected to the negative pressure generating assembly, and the negative pressure channel has an airflow channel 211 opened towards the preset shredding position. After the negative pressure generating assembly is activated, or the operating power of the negative pressure generating assembly is increased, the predetermined filament cutting position and the surrounding air are drawn into the air flow channel 211, so that the filament end 2101 or the portion of the to-be-wound piece near the filament end 2101 is trapped at the predetermined filament cutting position.

Obviously, the wire end 2101 or the wire section 210 intercepted by the airflow generating device 21 is a non-contact interception mode, the wire section 210 does not contact with the interception mechanism 20, the wire can be prevented from being bent and damaged due to the contact interception mode, and finally the obtained spinning wire product is smooth and has excellent quality.

Of course, other types of entrapment mechanisms 20 may be employed if the purpose of protection of the wire is not considered. For example, in other embodiments, the catching mechanism 20 includes a movable clamp capable of switching between a pinching state and an open-close state, the movable clamp directly grips the fixed filament end 2101 or the filament segment 210 to catch the filament end 2101 or the filament segment 210 when switched to the pinching state, and after switched to the open-close state, the movable clamp releases the restraining force on the filament end 2101 or the filament segment 210 to release the filament segment 210. The catching mechanism 20 may further include a tensioning drive source for driving the movable clamp, and after the movable clamp clamps the thread end 2101 or the thread piece 210, the tensioning drive source drives the movable clamp to move moderately, so that the piece to be wound is kept tensioned in real time and the slack phenomenon of the thread is eliminated, for example, when the movable clamp clamps the thread end 2101 at the preset thread cutting position, the tensioning drive source drives the movable clamp to move away from the preset thread cutting position, so that the thread end 2101 passes the preset thread cutting position, and the part of the piece to be wound close to the thread end 2101 passes the preset thread cutting position.

Referring again to fig. 1, the yarn collecting apparatus 100 further includes a comb unit 50, the comb unit 50 includes a plurality of comb fins arranged in parallel and at equal intervals, and the specific installation position of the comb unit 50 is various and the number is not limited specifically. Due to the fact that the number of the silk threads in the section to be wound is large, the silk threads can be smoother and smoother under the combing of the combing unit 50, and the silk threads can be prevented from being wound or adhered to each other. When the number of the comb units 50 is plural, the arrangement direction of the comb fins in one of the comb units 50 may be the same as or different from the arrangement direction of the comb fins in the other comb unit 50.

Referring again to fig. 1, the side pushing mechanism 30 includes a wire-pushing member 31 for directly contacting the section to be wound, and a side pushing driving source 32 connected to and capable of driving the wire-pushing member 31 to move relative to the wire feeding mechanism 10 and/or the retaining mechanism 20. Optionally, in the embodiment shown in fig. 1, the side pushing mechanism 30 further includes a guide frame 33 for guiding the jackscrew 31 to move along the fixed side pushing track; in addition, the side pushing mechanism 30 may also adopt a second transmission member similar to the first transmission member, the second transmission member is connected to the power output end of the side pushing driving source 32 in a follow-up manner and is in frictional connection with the top thread member 31, and the maximum static friction force between the second transmission member and the top thread member 31 is set to be smaller than the minimum external force required for breaking the thread.

The movement of the wire-pushing member 31 by the side-pushing drive source 32 via the second transmission member may be defined as the driving side-pushing movement of the wire-pushing member 31, and the speed of the driving side-pushing movement of the wire-pushing member 31 is set to be not greater than the wire-feeding linear speed of the wire-feeding mechanism 10, where the driving side-pushing movement speed of the wire-pushing member 31 is the linear speed of the movement of the wire-pushing member 31 in response to the output of the power of the side-pushing drive source 32, so that the change amount of the bending length of the wire section, i.e., the wire section buffer amount, of the wire section moved by the wire-pushing member 31 is not greater than the wire-feeding amount of the wire-feeding mechanism 10 at the same time. The significance of this is that when the side pushing mechanism 30 moves and buffers the thread, the portion of the section to be wound can form a certain length margin, and the length margin can enable the section to be wound to be loosened properly so as to reduce the tensile force applied to the section to be wound. If the following situation occurs: the unloaded silk winding member 41 is not installed in place for a longer period of time, and a longer time is needed for buffering the silk thread, which means that the buffering length of the silk thread is not enough, and the top silk member 31 needs to perform active lateral pushing movement. In this case, the length allowance can delay the speed of the to-be-wound section from a relaxed state to a tensioned state, and the possibility of the yarn being pulled apart is reduced.

Further, in one embodiment not shown in the figures, the filament collecting device 100 further comprises a first sensing unit for sensing whether the filament end 2101 or the filament section 210 is present at the preset filament cutting position. If the sensing result is that the preset filament cutting position has no filament end 2101 or filament segment 210, it indicates that the filament is not cut, the filament feeding mechanism 10 is in a state of supplying the filament to the filament receiving mechanism 40, and the filament winding member 41 does not reach a full load state, and can continue to wind and carry the filament, then the side pushing mechanism 30 does not act, or moves and reduces the forward bending length of the segment to be wound to release the filament; if the sensing result is that the filament end 2101 or the filament segment 210 exists at the preset filament cutting position, which indicates that the filament is cut, the filament receiving mechanism 40 stops receiving and winding the collected filament, the side pushing mechanism 30 starts to operate and pushes the segment to be wound to move laterally so as to increase the downbent length of the segment to be wound.

Further, in an embodiment not shown in the drawings, the yarn collecting device 100 further includes a second sensing unit for sensing whether the yarn winding member 41 is connected to the yarn drawing driving source or whether the yarn winding member 41 is connected to the yarn drawing driving source through the first transmission member. If the sensing result shows that no silk winding piece 41 is connected with the silk pulling driving source, the silk thread end 2101 or the silk segment 210 is trapped at the preset silk cutting position, the silk thread is cut off, the silk winding mechanism 40 stops bearing and winding the collected silk thread, and the side pushing mechanism 30 starts to run and pushes the segment to be wound to move laterally to buffer the silk thread; if the sensing result shows that the wire winding member 41 is connected with the wire drawing driving source, the wire is not cut, the wire feeding mechanism 10 is in a state of supplying the wire to the wire winding mechanism 40, the wire winding member 41 is not in a full load state, and the wire can be continuously wound, then the side pushing mechanism 30 does not act, or moves and reduces the smooth bending length of the section to be wound to release the wire.

Of course, it is also possible to provide an active control switch for the thread collecting device 100, and the person can control the switching of the motion state of the side pushing mechanism 30 and change the downbent length of the section to be wound by manipulating the active control switch.

The steps of the method for controlling the transport of a thread are described below:
