Description
Technical Field
The invention relates to the field of spinning cake processing, in particular to an automatic thread take-up device.
Background
In the textile field, the processes of heading, stripping, knotting and the like of spinning cakes are generally performed manually at present. However, there are many inconveniences, for example, some filament vehicles are as high as one meter and seven just by the head beam, and a shorter operator is very inconvenient to perform the operations of stripping filament from cake, knotting and inspecting broken filament at the uppermost layer. The precision of manual operation by an operator varies from person to person and very high precision cannot be guaranteed. In particular, when an elderly operator is not sufficient in physical strength, the accuracy further decreases.
Knotting is an essential part in the spinning process, the stability of knotting is an important condition for ensuring the quality of finished fiber products, and after the packaged polyester filament yarns are stripped, the packaged polyester filament yarns need to be sent into a warehouse for storage so as to be packaged or sent into the next procedure for continuous processing. If the package spinning cake filament head is not fixed, the filament head can be scattered in the transportation process. The scattered thread ends are easy to be wound on other objects, and the wound thread ends are messy, so that the influence of inconvenient operation on the next procedure is caused.
As shown in figure 3, (a) is a cone knot, and at present, in the textile industry, the knot tying is convenient to operate and can be carried out by hands, but the knot is large, the knot head is easy to loosen, and the tail length of the knotted tail end of the existing mechanical knotter for the cone knot reaches 4-6 mm.
(b) For weaving cloth knots, the knot form is characterized in that the ends pass through the center and are distributed on two sides, the knots are small and firm, the knot is suitable for yarns with various fibers and various linear densities, and the knot is particularly suitable for thin yarns and high-density fabrics, but the knot is easy to be removed when compared with smoother yarns. The existing mechanical knotter for weaving cloth knots is suitable for cotton and cotton chemical fibers with the density of 10-58tex, and the ending length is 3-6 mm.
(c) The knot is a plain knot, namely, the knot is knotted by hands, the knot is small, but the knotting method is troublesome, the knot has poor firmness, and the knot is easy to be broken. (d) The self-tightening knot is composed of two incomplete knots, the ends are opposite, the knot roots are opposite, and the two incomplete knots are combined into a whole when the self-tightening knot is tightened. The existing self-fastening mechanical knotter is suitable for cotton and cotton chemical fibers with the density of 18-58tex, and the tail length is 4-7 mm. The action principle of the self-tightening mechanical knotter is mainly as follows: two cotton yarns are respectively placed into the bottoms of the left yarn groove and the right yarn clamping groove by two hands of an operator; the left palm presses the handle to drive the gear hook to rotate, at the moment, the gear hook can complete hooking of cotton yarn, the cotton yarn enters a cutter edge of the gear hook, the cutter edge cuts the cotton yarn and simultaneously the knot is tightly hooked and opened, a yarn ring is pulled out, and the knot is tied into a series of actions. The knotter drives the gear hook to rotate by pressing the handle to complete thread picking, but the thread picking function is in the current single thread knotting process, and the mechanism and the principle are not applicable. In summary, the knotting of single thread in the factory is still performed manually, and therefore the thread picking in the knotting process is also still performed manually.
Therefore, the manual-to-automatic conversion of single silk thread knotting is urgently needed, the automatic knotting machine simulates an artificial thread picking process while realizing automatic knotting of the silk threads, whether the defects in the prior art exist is overcome, the improved automatic thread picking device is provided, manual thread picking can be replaced, and meanwhile the multi-degree-of-freedom space thread picking mechanism with high stability and high reliability is provided, so that the technical problem to be solved urgently by technical personnel in the field is solved.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying 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 given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, the automatic thread take-up device of the first embodiment is used for a knotter that knots threads on a cake, and includes: the device comprises a frame 1, a lifting mechanism 2, a movement mechanism 3, a rotation mechanism 4 and a thread take-up mechanism 5. The lifting mechanism 2 is preferably an air cylinder, but is not limited thereto, and other devices may be employed. The movement mechanism 3 is preferably a lead screw module, but is not limited thereto, and other devices may be employed. The thread take-up mechanism 5 is preferably a thread take-up bar, but is not limited thereto, and other devices may be employed. The lifting mechanism 2 is arranged on the frame 1, the moving mechanism 3 is arranged on the lifting mechanism 2, and the rotating mechanism 4 is arranged on the moving mechanism 3. The thread is fixed on the thread take-up mechanism 5 in the process of the action of the automatic thread take-up device. The rotating mechanism 4 comprises a driving source 6, a transmission mechanism is arranged on the driving source 6, and the thread take-up mechanism 5 is arranged on the transmission mechanism. As shown in fig. 2, the thread take-up mechanism 5 is provided with a thread insertion groove 7. The thread picking process is as follows, the thread picking mechanism 5 moves up and down through the lifting mechanism 2 to complete thread finding action, meanwhile, the moving mechanism 3 drives the thread picking mechanism 5 to realize transverse movement to complete thread taking action, and when the spinning cake is moved to a certain position, the driving source 6 on the rotating mechanism 4 can drive the thread picking mechanism 5 to complete thread forming action. The silk thread can slide to the silk embedding groove 7 on the take-up mechanism 5 to finish the action of fixing the silk thread, and a coil can be formed above the silk cake when the driving source 6 drives the take-up mechanism 5 to rotate for a specific angle, so that the whole take-up action is finished.
The lifting mechanism 2 replaces the action that the hands need to be repeatedly lifted and put down in manual yarn picking, and the problem that the hands easily touch the surface of a spinning cake to cause broken filaments is solved. The motion mechanism 3 replaces the action of manually picking the threads, which needs to move the hand above the spinning cake to start the threads. The stroke (horizontal direction) of the motion mechanism 3 is larger than the stroke (up and down) of the lifting mechanism 2.
The driving source 6 drives the thread take-up mechanism 5 to realize the thread forming action of the process steps, and the problem that broken threads appear on a spinning cake due to the fact that a worker can touch silk threads in the thread finding process is effectively avoided.
The height of the thread picking mechanism 5 is 10mm larger than the radius of the spinning cake, so that the thread picking rod is close to the spinning cake as much as possible when the thread is picked, and the space waste caused by too large distance is avoided.
The thread take-up mechanism 5 has a certain slope (inclined plane), and the inclined plane is convenient for the silk thread to slide into the silk embedding groove 7 along the inclined plane, so that the position of the silk thread is fixed, and the uncertainty of the position of the silk thread is avoided. The wire embedding groove 7 has a certain radian and depth, so that the silk thread can be prevented from being broken, and the position of the coil is fixed.
As described above, according to the automatic thread take-up device of the first embodiment, compared with the prior art, the automatic thread take-up device can replace manual thread take-up, so that the feasibility of knotting and thread taking-up is improved, and the problems of low efficiency and many uncontrollable factors of manual knotting are solved. In the process of manual knotting, actions required by a human hand include lifting, lowering, stretching, rotating and the like, and the automatic take-up device refers to the actions of the human hand and is more excellent than the human hand in the aspects of quality, speed, stability and the like. From the yarn picking quality, the final position of the coil picked manually is high and low, the device is determined relative to the position of the spinning cake, and the position of the coil picked finally is fixed, so that the smooth operation of the next procedure is facilitated. From the yarn picking speed, manual yarn picking is carried out on a yarn vehicle, the distance between a yarn cake and the yarn cake is small, other yarn cakes can be touched by hands inevitably while efficiency is pursued to cause the yarn cake to generate broken yarns, the speed cannot reach an optimal degree, the yarn picking mechanism adopted by the device is small in size, the broken yarns are avoided, and the speed can be greatly improved. From the suitability, for the silk of different sizes, the action range that the staff required is different, and this device can reach the adaptability to various silks by the stroke of adjusting device, has good commonality. From the view of the stability of thread picking, the force applied by manual thread picking cannot be controlled, the silk thread is easily broken in the thread picking process, and the device can find the optimal force required by thread picking by adjusting the driving source. This device is a multi freedom space thread take-up mechanism, has the artifical characteristics such as quick that can reach, accuracy, dexterity, very big assurance the authenticity of take-up, according to the problem that artifical take-up exists, improves on this basis, makes the device have the people function can reach quick, accurate, function such as dexterity, has improved the efficiency of knoing, realizes the automated processing to the spinning cake, reduces the human cost, improves production efficiency and automated production, realizes the intelligent processing to the spinning cake.
