Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of textile machines, in particular to a textile machine and a cheese conveying method of the textile machine. BACKGROUND

[0002] Modern textile equipment, such as rotor spinning machines, air-jet spinning machines or winding machines, is usually composed of a head, a tail and multiple intermediate sections, and multiple same working units are arranged side by side in each section for winding yarns to form cheeses. In order to realize the centralized collection of the cheese packages, a unified annular conveying device is generally arranged along the longitudinal direction of the whole machine, and the circulating conveying is realized through a driving unit arranged at one end. With the expansion of the equipment scale, the whole conveying path may be as long as more than seventy meters, which makes the traditional integrated long-distance conveying structure have certain limitations in terms of operation energy consumption, scheduling efficiency and maintenance convenience.

[0003] For example, Chinese Patent Application Publication No. CN116692600A, entitled "Package conveying system and package conveying method", discloses a conveying system based on the dynamic adjustment of the conveying speed according to the weight or position information of the cheese packages. Although the system can improve the efficiency of the driving response to a certain extent, the system still takes a single long conveying path as the core, and the conveying of all cheese packages depends on a unified annular conveying belt driven by one driving unit. When the number of cheese packages increases dramatically or the load of the local path is unbalanced, the driving part may be overloaded and the response may be delayed. If a section is damaged or fails, the whole system often needs to be stopped for processing, which not only has high maintenance cost but also has long replacement cycle. At the same time, because it is a unified annular conveying belt, the problem of idle running and energy waste is easy to occur.

[0004] For another example, Chinese Patent Application Publication No. CN110482314B, entitled "Textile machine and sleeve conveying method thereof", proposes to arrange multiple sleeve storages on both sides of the textile machine and set multiple groups of pulling members for horizontal transportation, and adjust the direction of the sleeves by cooperating with the rotating device, so as to realize high-density storage and flexible distribution. The structure is suitable for pre-provision and type distribution of sleeves, but it mainly focuses on the "supply direction conveying" from the sleeve storages to the working units and does not involve the "collection direction conveying" of the finished cheese packages from the working units. Therefore, the scheme has not been optimized for segmented conveying and independent control of long paths, so it is still difficult to effectively improve the system response efficiency and path scheduling flexibility in the case of long cheese conveying path and strong segmented control demand. It also does not support classified conveying based on the type of yarn, which makes it difficult to meet the actual needs of "multi-variety parallel production and classified recycling management" in modern textile processes. SUMMARY

[0005] The present invention aims to overcome the shortcomings of the prior art by providing a textile machine and a bobbin delivery method thereof. By segmenting and modularizing the delivery path, each delivery segment is independently controlled. This not only enables segmented relay delivery of bobbins, improving the flexibility of delivery scheduling and system response efficiency, but also facilitates equipment installation, maintenance, and partial replacement. Furthermore, the textile machine can support the parallel processing of different yarn types and deliver different types of bobbins to corresponding discharge areas based on bobbin information, thereby improving the overall operating efficiency and adaptability of the machine.

[0006] The technical solution for achieving the purpose of the present invention is: a textile machine, including a machine body, a bobbin yarn delivery system and a control device, the machine body including a head and a tail and a plurality of segments arranged between the head and the tail, each of the segments having a plurality of similar working units arranged side by side with each other, the working units winding the yarn to form bobbins, and the bobbins are placed in the bobbin yarn delivery system for transportation after being discharged from the working units, the bobbin yarn delivery system including a plurality of conveyors arranged in sequence along the longitudinal direction of the textile machine, each conveyor being driven separately by the control device, and each conveyor being arranged in a corresponding segment, and its length being consistent with the length of the segment.

[0007] Furthermore, the conveyor includes an endless conveyor belt, and a first pulley and a second pulley arranged at both ends of the endless conveyor belt. The transport path formed by the endless conveyor belt is consistent with the length of the corresponding segment. At least one of the first pulley and the second pulley is a driving wheel, and the driving wheel is connected to the control device of the textile machine to drive the endless conveyor belt to circulate along a closed path.

[0008] Furthermore, the bobbin yarn transporting system further comprises a head conveyor and a tail conveyor respectively arranged at the head and tail of the textile machine, which respectively constitute the head discharge area and the tail discharge area of ​​the bobbin yarn.

[0009] Furthermore, each conveyor is provided with a sensor for detecting bobbins, and the sensor is connected to the control device of the textile machine. The control device drives the conveyor with bobbins retained and stops the conveyor without bobbins retained according to the information detected by the sensor.

[0010] Preferably, each conveyor corresponds to a section of the textile machine, and the length of each conveyor is consistent with the length of the section.

[0011] A bobbin yarn conveying method suitable for the textile machine, wherein the bobbin yarn produced by the working unit of the textile machine is placed in a bobbin yarn conveying system for transportation, and the bobbin yarn conveying system includes a plurality of conveyors arranged in sequence along the longitudinal direction of the textile machine, each conveyor corresponds to a corresponding segment, and the length of each conveyor is consistent with the length of the segment, and each conveyor conveys the bobbin yarn to the head or tail of the textile machine by relay transportation.

[0012] Furthermore, a sensor installed on each conveyor detects whether a bobbin has entered the conveyor, and sends a detection signal to the control device, which drives the conveyor with the bobbin remaining and stops the conveyor without the bobbin remaining.

[0013] Furthermore, the control device drives each conveyor to transport the bobbin yarn to the head discharge area or the tail discharge area of ​​the textile machine according to preset information.

[0014] Furthermore, the control device determines the target discharge area of ​​the bobbins produced in the preset section according to the preset information, and controls the corresponding conveyor to run in the said direction, so that the bobbins produced in the preset section are respectively conveyed to the predetermined discharge area.

[0015] After adopting the above technical solution, the present invention has the following positive effects:

[0016] (1) The present invention configures the bobbin yarn transport path in segments so that each conveyor corresponds to the corresponding segment of the textile machine and has independent control capabilities, thereby realizing segmented relay transport of bobbins, thereby improving the flexibility and response speed of path scheduling and helping to shorten the overall yarn dropping cycle.

[0017] (2) The present invention supports the delivery of different types of bobbins to the head or tail of the textile machine according to the type of bobbins produced, thereby achieving the purpose of processing multiple yarn varieties on the same equipment at the same time, thereby improving the spinning range and overall operating efficiency of the equipment.

[0018] (3) The present invention adopts a modular conveying structure design, so that each conveying unit can be installed and disassembled independently, and can be quickly replaced during equipment installation, daily maintenance or when a failure occurs, effectively reducing maintenance costs and improving system reliability.

[0019] (4) The present invention sets up sensors to detect whether there are bobbins on each section of the conveyor, and only drives the conveyor that actually carries the bobbins, avoiding the no-load operation of the invalid section, thereby reducing the system energy consumption and improving the energy efficiency and operation stability of the overall transportation system.

DETAILED DESCRIPTION

[0025] The technical solution of the present invention is described in detail below with reference to the accompanying drawings and embodiments. The accompanying drawings are only used for schematic description and do not constitute a limitation on the protection scope of the present invention.

[0026] like Figure 1 and Figure 2 As shown, this embodiment discloses a textile machine system suitable for modern textile technology, which can be an air-spinning machine (i.e., a rotor spinning machine), an air-jet spinning machine, or a winding machine. The following description takes the air-spinning machine as an example.

[0027] Figure 1 The figure shows a front view of an air-spinning machine, i.e., one longitudinal side of the air-spinning machine. However, air-spinning machines generally have two opposite longitudinal sides, and each longitudinal side contains the same number of workstations. The body 1 of the air-spinning machine as a whole includes a head 2, a tail 3, and a plurality of segments 4.1 to 4.N arranged therebetween in the longitudinal direction. The head 2 and the tail 3 may include bearings, drives, control devices, etc. that are necessary for the operation of the spinning machine. Each segment 4.1 to 4.N may include two opposite longitudinal sides, and each longitudinal side is provided with a plurality of working units 5 side by side with each other. For clarity, only one of the working units 5 is provided with a reference numeral. As shown in FIG. Figure 1 and Figure 2 As shown, each segment consists of two opposite longitudinal sides with a total of 20 stations 5, that is, Figure 1There are 10 working units 5 visible on the current side and 10 working units 5 on the other longitudinal side that is not currently visible. In fact, each section can of course be designed to have more or fewer working units 5. In addition, only two sections 4.1 and 4.2 are shown in full, while the third section 4.N is shown partially. Each working unit 5 spins the slivers stored in the sliver barrel 14 into yarn, and winds the spun yarn on an empty bobbin to form a cone yarn 13. Specifically, each working unit includes a spinning device for spinning slivers and a winding device for winding the spun yarn on a bobbin. When the winding reaches a set length or weight, the cone yarn 13 is automatically discharged to the corresponding conveyor 7.1 (see Figure 2 In order to facilitate equipment assembly, transportation and maintenance, the textile machine structure adopts a modular segmented design, and each segment can be independently manufactured, installed, operated and disassembled.

[0028] A bobbin delivery system 6 is arranged on the top of each side of the air-spinning machine shown in this embodiment along the longitudinal direction. Figure 2 、 Figure 3 As shown, the bobbin conveying system 6 includes multiple conveyors 7.1 to 7.N. The head 2 and tail 3 of the air-spinning machine are further provided with a head conveyor 2.1 and a tail conveyor 3.1, respectively, which constitute the head and tail discharge areas of the bobbin. This modular conveyor design allows each conveyor to be independently installed, operated, and disassembled, allowing for quick replacement during equipment installation, routine maintenance, or in the event of a malfunction. This effectively reduces operating and maintenance costs and improves system reliability. According to this embodiment, each conveyor is located above a corresponding segment of the air-spinning machine. They are structurally independent and have a length consistent with that of the segment. Each conveyor is connected end-to-end to form a continuous conveying path. A corresponding conveyor is provided on one side of the air-spinning machine, and another corresponding conveyor is provided on the other side. That is, the spinning units on both sides of the air-spinning machine each correspond to a corresponding conveyor. Each conveyor can be independently operated and controlled under the unified management of the control device 12. The bobbins 13 produced in each working unit 5 are discharged onto the corresponding conveyor and then transported by the conveyor or multiple conveyors to a predetermined head discharge area at the front of the loom or tail discharge area at the rear of the loom. For example, it is conceivable that the bobbins produced by the working units of all segments on one side of the loom can be transported to the head discharge area, while the bobbins produced by the working units of all segments on the other side of the loom can be transported to the tail discharge area. Of course, it is also possible to transport the bobbins produced by all working units on both sides to the head discharge area or the tail discharge area. In addition, it is also possible to arrange that the bobbins produced by several selected consecutive segments on one side of the loom are transported to the head discharge area, while the bobbins produced by the other segments on that side are transported to the tail discharge area.

[0029] In other embodiments, the textile machine can also be a jet spinning machine, in which case the working units are similar and are used to process the sliver into yarn and wind it into a bobbin, the difference being that the spinning method is jet spinning. In another embodiment, the textile machine can be a winder, i.e. a machine that splices and winds different bobbins into a uniform size bobbin. The bobbin conveying system and method described in the present application can be used in the above-mentioned different types of textile machines.

[0030] As shown in Figure 3 Each conveyor 7.1 to 7.N is formed by a looped conveyor belt 8, the two ends of the conveyor belt are respectively provided with a first pulley 9 and a second pulley 10, and at least one end is provided with a driving motor (marked as M in the figure) to drive the conveyor belt to circulate. In addition, sensors 11 are also provided on the conveyors 7.1 to 7.N, at least one sensor 11 is provided on each conveyor 7.1 to 7.N, which can be known infrared or photoelectric sensors or weighing sensors and other known sensors. The sensors are arranged on the conveyors or the textile machine and are used to detect the bobbins 13 on the conveyors to ensure accurate sensing of the entry and exit of the bobbins. The sensors are connected to the control device 12 through data lines or wirelessly and transmit the detection results to the control device 12 in real time for corresponding scheduling judgment. If the sensor detects that there is no bobbin 13 on the conveyor, the control device 12 can stop the operation of the conveyor and make it enter the standby state, which can save the consumption of electric energy. When the sensor detects that there is a bobbin 13 on the conveyor, the control device 12 can drive the conveyor to operate and send the bobbin 13 to the predetermined head discharge area or tail discharge area according to the preset direction.

[0031] As shown in Figure 4 The flow chart of the bobbin conveying is shown in the figure and comprises the following steps:

[0032] S101: After the winding operation of the working unit 5 is completed, the formed bobbin 13 is discharged to the conveyor corresponding to the segment;

[0033] S102: The sensor 11 of each conveyor detects in real time whether there is a bobbin on each conveyor;

[0034] S103: If no bobbin is detected, the conveyor remains in the standby state to avoid invalid operation;

[0035] S104: If a bobbin is detected, a signal is fed back to the control device 12;

[0036] S105: After receiving the detection signal, the control device 12 reads the information of the bobbin, which can include yarn variety, bobbin size, preset weight and other parameters;

[0037] S106: The control device drives the conveyors to transport the cones to the pre-set discharge area according to the information of the cones;

[0038] S107: The cones are transferred from the initial conveyor to the next conveyor in a relay manner until they reach the target discharge area.

[0039] Further, since the textile machine is symmetrically arranged on both sides, each side is equipped with an independent conveying system 6 and control logic, that is, each side can operate independently, so the embodiment can support the processing of different yarn types on both sides of the textile machine, realizing the synchronous production of multiple categories. For example: one side of the textile machine processes cone yarn of variety A, and the other side processes cone yarn of variety B. The cone yarn of variety A is set to be transported to the head discharge area, and the cone yarn of variety B is set to be transported to the tail discharge area. Further, several consecutive segments on one side of the textile machine can be selected to process cone yarn of variety C, and the other segments can process cone yarn of variety D. Among them, the cone yarn of variety C is set to be transported to the head discharge area, and the cone yarn of variety D is set to be transported to the tail discharge area. In order to realize efficient classified transportation and subsequent processing.

[0040] The above specific embodiments further illustrate the purpose, technical solutions and beneficial effects of the present application. It should be understood that the above description is only a specific embodiment of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
