Description

Technical Field

[0001] This invention relates to the field of textile machinery technology, and specifically to an automatic device and method for processing and feeding yarn tubes. Background Technology

[0002] In operation, the traditional yarn-silo type winding machine requires an operator to locate the yarn ends and place them one by one into each spindle's silo. This process is labor-intensive, averaging one worker per machine, resulting in low production efficiency. Therefore, while retaining the existing yarn-silo type winding machine, there is an urgent need to upgrade it to increase automation, reduce labor costs, and improve equipment efficiency.

[0003] Currently, there are two types of technology for modifying yarn storage type winding machines:

[0004] A yarn end finding device, patent number CN201921908550, is proposed to be integrated into an AGV mobile platform. It includes a yarn buffer mechanism, a translation mechanism, a yarn end finding mechanism, and a yarn drive mechanism. This integrates functions such as scraping, sucking up, and blowing up yarn ends onto a mobile AGV trolley. The mobile AGV trolley can move back and forth within the entire winding machine and perform real-time yarn end finding. While this mechanical device can reduce the labor intensity of the machine operator by circulating yarn, it occupies a large space, requiring a specific workshop layout. Furthermore, the mobile AGV trolley has poor reliability and is prone to accumulating lint and fibers, causing equipment damage.

[0005] The second type involves modifying a tray-type winding device, patent number CN202021709662. It retains the existing yarn storage winding machine's working unit but adds a tray conveyor line to transport the yarn tubes below the winding machine's working unit for winding, eliminating the need for manual yarn feeding. This structure is relatively stable, but the front and rear circulating belts are prone to accumulating fly shavings, causing jamming and affecting equipment operation. Additionally, the connection between the front and rear belts is also a belt conveyor, which can easily entangle the yarn, leading to problems when changing yarn tubes.

[0006] The existing equipment is a manual tube-insertion winding device, which requires manual pushing of the yarn basket trolley to put the manually positioned yarn tube into the small yarn chamber of each spindle. Then the spindle starts to wind the yarn. The empty yarn tubes after unwinding are collected and processed uniformly through the empty tube circulation belt of the device. Summary of the Invention

[0007] This invention provides an automatic device and method for processing and feeding bobbins, the purpose of which is to improve the production efficiency of equipment operation.

[0008] To achieve the above objectives, the technical solution of the present invention is as follows:

[0009] This invention provides an automatic processing device and method for feeding bobbins, including a bobbin feeding hydraulic device, a bobbin identification and insertion device, a bobbin centralized processing device, a bobbin centralized processing control cabinet, a bobbin circulating conveying platform, a single spindle of a yarn storage type winding machine, a machine head negative pressure device, and a single spindle tube changing device;

[0010] The yarn basket filled with tube yarn is fed into the tube yarn identification and insertion device by the tube yarn feeding hydraulic device.

[0011] In the yarn tube identification and insertion device, the vibration of the vibrating plate drives the yarn tube to move and align.

[0012] Then, using the yarn tube size detection sensor, the yarn tube is inserted into the tray of the yarn tube centralized processing device with the larger end facing down;

[0013] In the centralized processing device for bobbins, the conveyor belt drives the tray to send the bobbins into the working area. The head finding component, in conjunction with the negative pressure device at the head of the machine, finds the head of the bobbin and puts it into the bobbin. Then, the bobbin enters the bobbin circulation conveying platform in sequence.

[0014] The processed bobbins enter the bobbin circulation conveyor platform and are conveyed by belt circulation. The bobbins are then fed one by one into the single-spindle bobbin changing device under the single spindle of the yarn silo type winding machine.

[0015] The single-spindle tube changing device uses a cylinder to drive a shift fork to feed a full tube of yarn into the single-spindle winding position, or to discharge empty tubes or abnormal tubes of yarn that have been unwound to the tube-to-yarn circulation conveyor platform.

[0016] Abnormal or empty tubes enter the centralized tube processing device via the tube pre-circulation conveyor platform, where they are pulled out before entering the next cycle.

[0017] The beneficial effects achieved by this invention are as follows:

[0018] This invention discloses an automatic processing device and method for feeding bobbins. Compared with the previous technology that used a bobbin-changing conveyor belt, this patent uses a motor or cylinder drive, which makes the equipment more reliable and easier to maintain and requires no maintenance.

[0019] Compared with previous technologies, the centralized yarn processing device used in this patent has a wider range of applications, including cotton, chemical fiber and blended single yarns or plied yarns, with counts ranging from Nm10 to the highest count.

[0020] Compared with previous technologies, this patent adds negative pressure suction devices to the front and rear conveyor belts of the equipment to ensure the cleanliness of the conveyor belts and prevent the accumulation of fly shavings from getting tangled. Attached Figure Description

[0030] This invention relates to textile machinery and equipment, which is a modification of the yarn storage type winding machine. The main winding structure of the yarn storage type winding machine is retained, and six main parts are added: a bobbin feeding hydraulic device, a bobbin identification and insertion device, a bobbin centralized processing device, a bobbin centralized processing control cabinet, a bobbin circulation conveying platform, and a single spindle tube changing device.

[0031] This invention retains the existing structure of the yarn storage type winding machine to the greatest extent possible, while solving the problems of low equipment efficiency, high labor requirements, and inconvenient maintenance.

[0032] After modification according to this patented solution, one operator can patrol 3-4 machines, reducing labor by 67%-75%; the yarn bobbin, which previously required manual insertion, is now centrally processed and automatically fed into the spindle by a conveyor belt, greatly improving equipment efficiency; the yarn storage for each spindle is removed after the modification, leaving ample space for personnel to maintain and repair the equipment, greatly improving operability.

[0033] Figure 3 The diagram shows the equipment before the modification. Before the modification, the equipment was a manual tube-insertion winding device. It required manual pushing of the yarn basket trolley 5 to put the manually positioned yarn tube into the small yarn chamber 3 of each spindle. Then the spindle was started to wind the yarn. The empty yarn tubes after unwinding were collected and processed uniformly through the empty tube circulation belt 4.

[0034] Figure 1 This is a schematic diagram of the equipment after modification, including eight main parts: a bobbin feeding hydraulic device 11, a bobbin identification and insertion device 12, a bobbin centralized processing device 13, a bobbin centralized processing control cabinet 14, a bobbin circulating conveyor platform 15, a single spindle of a yarn storage type winding machine 16, a machine head negative pressure device 17, and a single spindle tube changing device 18. Among them, the single spindle of the yarn storage type winding machine 16 and the machine head negative pressure device 17 are the retained winding machine working units of the yarn storage type winding equipment, i.e. Figure 3The existing yarn warehouse winding machine single spindle 1 and the existing machine head negative pressure device 2, and the tube yarn centralized processing control cabinet 14 are used to control the operation of each part.

[0035] This invention provides an automatic method for feeding bobbins, including: bobbin feeding, bobbin identification, bobbin movement and arrangement, bobbin size determination, inserting the bobbin with the larger end facing down into a tray, feeding the bobbin into the working area, finding the bobbin end and feeding it into the bobbin circulation conveying platform, processing the bobbins one by one into the single-spindle bobbin changing device, feeding the full bobbin into the single-spindle winding working position, and simultaneously processing empty or abnormal bobbins before entering the next cycle.

[0036] An automatic yarn feeding device includes 11 a yarn feeding hydraulic device, 12 a yarn identification and insertion device, 13 a yarn centralized processing device, 14 a yarn centralized processing control cabinet, 15 a yarn circulating conveying platform, 16 a yarn silo type winding machine spindle, 17 a machine head negative pressure device, and 18 a single spindle tube changing device.

[0037] The yarn basket filled with tube yarn is fed into the tube yarn identification and insertion device by the tube yarn feeding hydraulic device.

[0038] In the yarn tube identification and insertion device, the vibration of the vibrating plate drives the yarn tube to move and align.

[0039] Then, using the yarn tube size detection sensor, the yarn tube is inserted into the tray of the yarn tube centralized processing device with the larger end facing down;

[0040] In the centralized processing device for bobbins, the tray is driven by a conveyor belt to send the bobbins into the working area. The head finding component, in conjunction with the negative pressure device of the 17 machine head, finds the head of the bobbin and puts it into the bobbin. Then, the bobbin enters the bobbin circulation conveying platform in sequence.

[0041] The processed bobbins enter the 15a bobbin circulation conveyor platform and are conveyed by belt circulation. The bobbins are then fed one by one into the 18 single-spindle bobbin changing device under the single spindle of the 16 yarn silo type winding machine.

[0042] The 18-spindle tube changing device uses a cylinder to drive a shift fork to feed a full tube of yarn into the single-spindle winding position, or to discharge unwound empty tubes or abnormal yarn tubes to the 15b tube-to-yarn pre-circulation conveyor platform.

[0043] Abnormal or empty tubes enter the 13-tube centralized processing device via the 15b tube pre-circulation conveyor platform. After tube removal, they enter the next cycle.

[0044] The above description is merely an optional embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
