Description

Technical Field

[0001] The invention belongs to the technical field of spinning engineering machinery, and in particular relates to a material taking and lifting mechanism. Background Art

[0002] With the development of automation technology, in the spinning engineering machinery industry, winding machines have also made great progress. More and more winding machine manufacturers have designed fully automated winding machines to replace the original automatic winding machines. However, the fully automated winding machine equipment has a high degree of integration, which makes maintenance inconvenient. Once the equipment fails, it needs to be shut down for a long time for maintenance; and most of the fully automated winding machines are still provided by several large foreign companies, and the equipment and machines are expensive.

[0003] There are still a large number of automatic winding machines in my country's textile enterprises. Although they have their own yarn warehouse and can automatically put yarn tubes in the winding process, they still need supporting workers to put the yarn tubes into the yarn warehouse. With the increase in labor costs and the increasingly fierce competition in the textile industry, textile enterprises need to seek to transform and upgrade the existing automatic winding machines to replace workers in yarn feeding operations, reduce labor costs, and improve the degree of automation in production workshops, but avoid the high cost of purchasing new fully automated equipment.

[0004] At present, many manufacturers have conducted research on the automated yarn delivery system of automatic winding machines, such as CN201610657354.2 automatic yarn delivery device, which has made some developments and descriptions around the pre-finishing of the yarn, but has not given sufficient explanation of the yarn delivery system and platform.

[0005] Our company has also carried out certain research and development in this field, and has applied for a series of patents such as CN201810459188.4 an automatic head finding device for automatic winding machine, CN201810459241.0 a conveying system for automatic yarn feeding equipment, CN201810459168.7 an automatic yarn feeding equipment for automatic winding machine, CN201810459167.2 a head finding and sorting system for automatic head finding equipment of automatic winding machine, etc.

[0006] However, during the production test process, it was found that the existing automatic yarn feeding system still had problems such as too high a degree of structural integration, which led to inconvenience in disassembly and maintenance. Therefore, a yarn feeding system for an automatic winding machine was further upgraded and improved in order to better meet the real needs of textile companies. Summary of the invention

[0007] In view of the technical problems in the prior art that the automatic winder structure is too integrated and inconvenient to disassemble and repair, the applicant has developed a new type of automatic winder yarn feeding system with high working efficiency and easy disassembly and maintenance. The purpose of the present invention is to provide a material taking and lifting mechanism for lifting the bobbin yarn and pushing it to the upper yarn feeding platform, which serves as a stable feeding guarantee mechanism for the multi-layer conveying platform of the automatic winder yarn feeding system.

[0008] The material taking and lifting mechanism of the present invention comprises:

[0009] The material taking and lifting mechanism body (361) plays a supporting role;

[0010] The material taking and lifting mechanism guide rail (362) is vertically arranged on the material taking and lifting mechanism body (361);

[0011] A material taking and lifting mechanism slider is slidably mounted on the material taking and lifting mechanism guide rail (362);

[0012] A first lifting plate (367) connected to a sliding block of a material taking and lifting mechanism;

[0013] The second lifting plate (368) is located directly above the first lifting plate (367), and the first lifting plate (367) and the second lifting plate (368) are supported and connected via a second spring guide device (369);

[0014] A second lifting drive mechanism is installed on the material taking and lifting mechanism body (361) and is used to drive the first lifting plate (367) to move up and down;

[0015] A second lifting limit device (370) is disposed on the top of the material taking and lifting mechanism body (361) and is used to limit the highest position of the second lifting plate (368);

[0016] A second bottom tube yarn storage platform (376) is connected to one side of the second lifting plate (368); a second pusher plate (371) is slidably mounted on the second bottom tube yarn storage platform (376);

[0017] The second gear rack system includes a third rack (372), a third gear (373), a fourth gear (374) and a fourth rack (375). The third rack (372) is horizontally arranged and connected to the second push plate (371) and has the same movement direction; the third gear (373) is meshed with the bottom of the third rack (372) and is supported by a bearing support system fixed on one side of the second lifting plate (368); the fourth gear (374) is located on one side of the first lifting plate (367) and is coaxially and tightly connected to the third gear (373); the fourth rack (375) is vertically connected to the first lifting plate (367) and meshed with the fourth gear (374).

[0018] When the material-collecting and lifting mechanism is actually in operation, under the drive of the second lifting drive mechanism, the first lifting plate (367) drives the second lifting plate (368) to rise together through the second spring guide device (369), and then the second lifting plate (368) contacts the second lifting limit device (370), so that the second lifting plate (368) stays at a limited height. Even if the second bottom tube yarn storage platform of the second lifting plate (368) is flush with the upper platform conveying track (301) of the automatic yarn feeding platform (3), at this time, due to the second spring guide device (369), the second lifting drive mechanism can continue to drive the first The lifting plate (367) continues to move upward. When the first lifting plate (367) compresses the second spring guide device (369), the second gear rack system starts to operate, and the first lifting plate (367) drives the fourth rack (375) to move upward, thereby causing the fourth gear (374) to rotate. At this time, the third gear (373) rotates synchronously, driving the third rack (372) to achieve horizontal movement, so that the second push plate (371) connected to the third rack (372) can be pushed to move, and the bottom support and the tube yarn are pushed from the second bottom tube yarn storage platform (376) to the upper platform conveying track (301).

[0019] Preferably, the second lifting drive mechanism comprises a second lifting drive motor (354), a second lifting drive lead screw (365) and a second drive nut; the second lifting drive motor (354) for picking up materials is installed on the top of the picking up and lifting mechanism body (361); the second lifting drive lead screw (365) is parallel to the picking up and lifting mechanism guide rail (362) and connected to the output end of the second lifting drive motor (354); the second drive nut is installed on the first lifting plate (367) and is threadedly sleeved on the second lifting drive lead screw (365). When the second lifting drive motor (354) is running, it drives the second lifting drive lead screw (365) to rotate, thereby causing the threaded second drive nut to move up and down, and finally realizing the up and down movement of the first lifting plate (367).

[0020] Preferably, the second lifting limit device (370) includes a second U-shaped seat and a second limit column, the end of the second U-shaped seat is fixed to the material picking and lifting mechanism body (361), and the second limit column is vertically fixed to the second U-shaped seat and has a second convex cap on the upper end.

[0021] The beneficial effects of the present invention are:

[0022] 1) A key point of the new automatic winding machine yarn throwing system developed by the applicant is that the bobbin and the bottom support are transported through a multi-layer conveyor belt, and the structure is compact; and in view of the long working position of the winding machine, the bobbin is transported from both ends to improve the working efficiency. The material taking and lifting mechanism of the present invention is used to lift the bobbin and push it to the upper yarn throwing platform, as a stable feeding guarantee mechanism for the multi-layer conveying platform of the automatic winding machine yarn throwing system.

[0023] 2) The material taking and lifting mechanism of the present invention adopts an integrated design of a lifting drive mechanism and a gear rack system, and realizes movement in two directions by one drive system. After lifting the bobbin and the bottom support to the preset position, the material can also be pushed horizontally. There are fewer parts and components, which effectively reduces the cost.

[0039] The present invention will be further described below in conjunction with specific examples. It should be understood that the following examples are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0040] Example 1

[0041] The material taking descending mechanism and the material taking lifting mechanism of the present invention will be described in more detail below in conjunction with the schematic diagram, wherein the preferred embodiment of the present invention is shown, and it should be understood that the present invention described herein can be modified by those skilled in the art, and still achieve the advantageous effects of the present invention. Therefore, the following description should be understood as being widely known to those skilled in the art, and not as a limitation of the present invention.

[0042] like Figure 1 As shown, a new type of yarn throwing system for automatic winding machine developed by the applicant is applied to the material taking down mechanism and the material taking up and lifting mechanism of the present invention. In the yarn throwing system for automatic winding machine, the control system 1 of the winding machine and the automatic winding machine 2 are original equipment. For the automatic winding machine 2, an automatic yarn throwing platform 3 is arranged on its working side, and the automatic yarn throwing platform 3 is used to throw the corresponding bobbin yarn into the winding station waiting for material, so as to meet the production needs of the automatic winding machine 2; the equipment matched with the automatic yarn throwing platform 3 includes an intermediate docking system 4, a bobbin yarn finishing system 5, and a bobbin yarn storage and lifting system 6.

[0043] Different from the original technical solution of our company (CN201810459241.0 A conveying system for automatic yarn feeding equipment), the automatic yarn feeding platform 3 is arranged on the working side of the automatic winder 2, flush with the winding station of the automatic winder 2, and the automatic yarn feeding platform 3 is arranged in sections and connected to each other to meet the bobbin yarn feeding needs of the entire automatic winder 2 production line.

[0044] The bobbins to be wound are first stored in the bobbin storage and lifting system 6, and then transmitted to the bobbin finishing system 5 one by one, and the bobbins are sorted and pre-processed so that the bobbins are installed on the special bottom tray, and then transferred to the automatic yarn feeding platform 3 by the intermediate docking system 4 for transportation; the automatic yarn feeding platform 3 will also transport the empty bottom tray after the yarn feeding is completed back to the corresponding channel of the bobbin finishing system 5 by the intermediate docking system 4 for the insertion of new bobbins to be wound.

[0045] like Figure 2 As shown, it is a structural schematic diagram of the automatic yarn throwing platform 3. According to the working condition of the above-mentioned automatic winding machine 2, the automatic yarn throwing platform 3 is divided into two modules, namely, yarn throwing platform No. 1 31 and yarn throwing platform No. 2 32, which are respectively used to correspond to the winding working areas at the front and rear ends of the automatic winding machine 2; the two yarn throwing platforms have the same basic structure, both of which include a bracket and a three-layer conveying device and a yarn throwing device installed on the bracket; the three-layer conveying device is used to transport the tube yarn and the bottom support delivered by the intermediate docking system 4 along the working side of the automatic winding machine 2; the yarn throwing device is arranged above the three-layer conveying device and corresponds to each winding station, and is used to throw the tube yarn to the winding station where the material is waiting.

[0046] The brackets of yarn throwing platform No. 1 31 and yarn throwing platform No. 2 32 are connected to the automatic winding machine 2 through the pressure plate device 307 respectively; adjustable universal wheels 308 are provided under the brackets of yarn throwing platform No. 1 31 and yarn throwing platform No. 2 32 to play a mobile support role; platform push-pull handrails 309 are installed on the outer sides of yarn throwing platform No. 1 31 and yarn throwing platform No. 2 32, and through the platform push-pull handrails 309, yarn throwing platform No. 1 31 or yarn throwing platform No. 2 32 can be independently pulled away from the automatic winding machine 2 for platform maintenance, or the automatic winding machine 2 can be repaired.

[0047] like Figure 3 , which is a schematic diagram of the installation of the pressing plate device 307; Figure 4 It is a partial schematic diagram of the pressing plate device 307; the automatic winding machine 2 has a side plate for supporting the machine body, and the automatic yarn feeding platform 3 is installed on the side plate through the pressing plate device 307. The pressing plate device 307 includes a pressing plate mechanism and a telescopic mechanism. The pressing plate mechanism includes two pressing plates 311, a pressing plate locking device 312, a guide device 313 and a guide rod locking device 315; the two pressing plates 311 clamp the side plates of the automatic winding machine 2 and are locked and fixed by the pressing plate locking device 312; the guide device 313 and the guide rod locking device 315 are fixed on the pressing plate 311. The telescopic mechanism includes a guide rod 314 and a floating joint 316, the guide rod 314 passes through the guide device 313 and the guide rod locking device 315, and the floating joint 316 is fixed to the end of the guide rod 314 and connected to the bracket of the No. 1 yarn feeding platform 31 or the No. 2 yarn feeding platform 32. When in use, the guide rod 314 can perform telescopic movement along the guide device 313 and the guide rod locking device 315, so that the No. 1 yarn throwing platform 31 or the No. 2 yarn throwing platform 32 can perform telescopic movement along the guide rods 314 on both sides of the platform, and the guide rod locking device 315 can be operated to lock the guide rod 314 so that it cannot move freely. The floating joint 316 is used to eliminate the up and down fluctuations caused by uneven ground during the platform movement.

[0048] Figure 5The figure is a schematic diagram of the structure of the pressure plate device 307; the guide rod 314 can be installed on the pressure plate 311 on one side of the pressure plate device 307 according to design requirements, or the guide rod 314 is provided on the pressure plates 311 on both sides, which mainly depends on the installation position of the pressure plate device 307. If it is installed on one end of the No. 1 yarn throwing platform 31 or the No. 2 yarn throwing platform 32, it is only necessary to provide a guide rod 314 on the side close to the yarn throwing platform to connect with the corresponding platform; at the junction of the two yarn throwing platforms, it is necessary to provide guide rods 314 on the pressure plates 311 on both sides, which are respectively connected to the yarn throwing platforms on both sides, and the two guide rods 314 are independent of each other, so that the two yarn throwing platforms can realize the telescopic pulling and pushing movement independently of each other.

[0049] Preferably, the guide rod 314 is a cylindrical guide shaft, and the guide device 313 is mainly a linear bearing. The guide rod locking device 315 is an axial guide locking device with a locking bolt, and has an operating handle. By rotating the operating handle, the guide rod 314 can be tightened or loosened to play a motion guiding role or a positioning locking role.

[0050] Preferably, a pull-out limit block 317 is provided at the other end of the guide rod 314, i.e., close to the guide rod locking device 315, and its cross-sectional size is larger than the inner hole of the guide rod locking device 315. Therefore, when the guide rod 314 is pulled outward, the pull-out limit block 317 can prevent the guide rod 314 from being accidentally pulled out, which would cause the guide limit to fail.

[0051] Preferably, one end of the two pressure plates 311 are connected together by bolts and nuts and clamped on the side plate of the automatic winder 2. The other end of the two pressure plates 311 is provided with a pressure plate locking device 312. The pressure plate locking device 312 is an eccentric locking device, and its main body is a bolt and nut device, and a handle with a cam is provided on the bolt head. The pressure plate locking device 312 is slightly tightened by manually adjusting the nut, and then fully tightened by operating the handle with the cam, so that the pressure plate locking device 312 fully tightens the ends of the two pressure plates 311, so that the two pressure plates 311 clamp the side plate of the automatic winder 2. In this way, during the installation and maintenance of the equipment, the structure can be disassembled, assembled and adjusted without tools, which is convenient for operation.

[0052] Figure 6 As shown, it is a schematic diagram of the guide rod pulled out state of the pressure plate device 307. At this time, the No. 1 yarn throwing platform 31 or the No. 2 yarn throwing platform 32 is pulled away from the winding station of the automatic winder 2, which can facilitate the maintenance of the yarn throwing platform or the inner winding station.

[0053] Figure 7 , which is a schematic structural diagram of the floating joint 316; Figure 8316 is a cross-sectional view of the adjustment structure of the floating joint 316; the floating joint 316 is installed at the end of the guide rod 314, which includes a guide rod seat 320 and a bracket seat 321. One end of the guide rod seat 320 is provided with a guide rod mounting hole 322, and the guide rod mounting hole 322 is provided with an opening. The guide rod mounting hole 322 is sleeved on the guide rod 314, and then the opening is locked by a screw to fasten the guide rod seat 320 to the guide rod 314; the working end of the guide rod seat 320 is a flat portion, which is provided with an adjustment slot 323, and the adjustment slot 321 is provided with a guide rod mounting hole 322. 23 is a vertically arranged long arc groove; the bracket seat 321 is fixedly installed on both sides of the No. 1 yarn throwing platform 31 or the No. 2 yarn throwing platform 32; a through groove is provided in the middle of the bracket seat 321, which is sleeved on the outer side of the flat part of the working end of the guide rod seat 320, and an adjusting bearing 324 is provided in the adjusting groove 323, and is fixed in the pin shaft hole 326 of the bracket seat 321 through a pin shaft 325. The bracket seat 321 can move up and down along the adjusting groove 323 relative to the guide rod seat 320 under the restriction of the adjusting bearing 324 to achieve adjustment.

[0054] The three-layer conveying devices of the No. 1 yarn throwing platform 31 and the No. 2 yarn throwing platform 32 are respectively the upper platform conveying track 301, the lower platform conveying track 302 and the bottom support recovery conveying track 310. Among them, the upper platform conveying track 301 of the No. 1 yarn throwing platform 31 and the No. 2 yarn throwing platform 32 is two independent transmission units running in opposite directions; the lower platform conveying tracks 302 of the No. 1 yarn throwing platform 31 and the No. 2 yarn throwing platform 32 are connected to form a conveying unit in the same direction, and the bottom support recovery conveying track 310 of the No. 1 yarn throwing platform 31 and the No. 2 yarn throwing platform 32 is arranged between the upper platform conveying track 301 and the lower platform conveying track 302, and is also connected to form a conveying unit in the same direction; the end of the No. 2 yarn throwing platform 32 is provided with a material picking and lifting mechanism 303. The No. 1 yarn throwing platform 31 and the No. 2 yarn throwing platform 32 are connected through a platform docking mechanism 304, but the upper platform conveying tracks 301 of the two yarn throwing platforms are not connected.

[0055] The intermediate docking system 4 is provided with a bottom support distribution mechanism 401, a material taking and descending mechanism 402, a lower-layer bobbin conveying channel 403 and an upper-layer bobbin conveying channel. Among them, the upper-layer bobbin conveying channel is docked with the upper-layer platform conveying track 301 of the No. 1 yarn throwing platform 31, and is used to deliver the assembled bobbin and the bottom support to the upper-layer platform conveying track 301. The material taking and descending mechanism 402 is arranged at the starting end of the lower-layer bobbin conveying channel 403, and is used to deliver the assembled bobbin and the bottom support downward to the lower-layer bobbin conveying channel 403. The lower-layer bobbin conveying channel 403 is docked with the lower-layer platform conveying track 302 of the No. 1 yarn throwing platform 31, and is used to deliver the assembled bobbin and the bottom support to the lower-layer platform conveying track 302. The bottom support distribution mechanism 401 is docked with the bottom support recovery conveying track 310 of the No. 1 yarn throwing platform 31, and is used to recycle the empty bottom support and divide it into two conveying channels for distribution and delivery back to the bobbin finishing system 5.

[0056] Fig. 9 The figure shows a schematic diagram of the docking between the No. 1 yarn throwing platform 31 and the intermediate docking system 4, which are separated to show the structure of the docking part, including an upper docking part 341 connected to the upper platform conveying track 301, which is used to transport the bobbin yarn output from the upper bobbin yarn conveying channel of the intermediate docking system 4 to the upper platform conveying track 301 of the No. 1 yarn throwing platform 31; a lower docking part 342 connected to the lower platform conveying track 302, which is used to transport the bobbin yarn output from the lower bobbin yarn conveying channel 403 of the intermediate docking system 4 to the lower platform conveying track 302 of the No. 1 yarn throwing platform 31, and further transport the bobbin yarn to the upper platform conveying track 301 of the No. 2 yarn throwing platform 32 for yarn throwing; and also includes a bottom support docking part 343 connected to the bottom support recovery conveying track 310, which is used to transport the empty bottom support generated after the No. 1 yarn throwing platform 31 and the No. 2 yarn throwing platform 32 have finished throwing yarn back to the intermediate docking system 4.

[0057] During operation, the No. 1 yarn throwing platform 31 and the No. 2 yarn throwing platform 32 can throw yarn at the same time. Specifically: the bobbin yarn and the bottom support outputted from the lower bobbin yarn conveying channel of the intermediate docking system 4 are sent to the upper platform conveying track 301 of the No. 1 yarn throwing platform 31, and the upper platform conveying track 301 of the No. 1 yarn throwing platform 31 moves forward with the bobbin yarn and the bottom support, and the bobbin yarn and the bottom support are delivered to the winding station where the material is waiting by the yarn throwing device on the No. 1 yarn throwing platform 31 to complete the yarn throwing; at the same time, the bobbin yarn and the bottom support outputted from the lower bobbin yarn conveying channel 403 of the intermediate docking system 4 are delivered to the No. 2 yarn throwing platform through the lower platform conveying track 302 of the No. 1 yarn throwing platform 31. The conveyor 302 of the lower platform of the No. 1 yarn throwing platform 32 is placed on the lower platform of the No. 2 yarn throwing platform 32, and then the material lifting machine 303 set at the end of the No. 2 yarn throwing platform 32 lifts the bobbin from the conveyor 302 of the lower platform of the No. 2 yarn throwing platform 32 to the conveyor 301 of the upper platform of the No. 2 yarn throwing platform 32. The upper platform of the No. 2 yarn throwing platform 32 carries the bobbin and the bottom support on the conveyor 301, and the direction of travel is opposite to the conveyor 301 of the upper platform of the No. 1 yarn throwing platform 31. The yarn throwing device on the No. 2 yarn throwing platform 32 will also complete the yarn throwing work at the same time. After the bobbin is thrown, the empty bottom supports on the No. 1 yarn throwing platform 31 and the No. 2 yarn throwing platform 32 will be sent to the bottom support recovery conveyor track 310 and sent back to the intermediate docking system 4.

[0058] Fig.10As shown, it is a partial schematic diagram of the No. 1 yarn throwing platform 31. The upper platform conveying track 301 is provided with two conveyor belts in the same horizontal plane, one is the tube yarn input conveyor belt 351, which is arranged on the side close to the yarn throwing device, and the other is the tube yarn circulation conveyor belt 352 which is arranged parallel to the outside; at both ends of the upper platform conveying track 301, a circulation guide mechanism 306 is provided between the tube yarn input conveyor belt 351 and the tube yarn circulation conveyor belt 352, and the circulation guide mechanism 306 is provided with a guide cylinder robot arm 353.

[0059] The yarn throwing device includes a yarn throwing robot 305, an entrance actuating cylinder 354, a yarn throwing area detection sensor 355, a bottom support bracket 356 and a bottom support bracket cylinder 359; the yarn throwing robot 305 is arranged on the upper platform conveying track 301 and corresponds to each winding station; the entrance actuating cylinder 354 and the yarn throwing area detection sensor 355 are arranged at the entrance of each yarn throwing area where the yarn throwing robot 305 is located, the bottom support bracket 356 is arranged above the bottom support recovery conveying track 310 and is provided with a bottom support downward sliding slope 358, and the bottom support bracket cylinder 359 is connected to the bottom of the bottom support downward sliding slope 358.

[0060] When the yarn is thrown in, at the entrance of the yarn throwing area where each yarn throwing robot 305 is located, the yarn throwing area detection sensor 355 first determines whether there is a bobbin in the yarn throwing area. When there is no bobbin, the entrance toggle cylinder 354 is opened, and the bobbin on the bobbin input conveyor belt 351 is placed in the yarn throwing area. At this time, the yarn throwing area detection sensor 355 detects the existence of the bobbin, so that the entrance toggle cylinder 354 is closed, and the bobbin on the bobbin input conveyor belt 351 can no longer enter the yarn throwing area; when the winding station needs a bobbin, the yarn throwing robot 305 acts to grab the bobbin in the yarn throwing area, lifts the bobbin, and rotates it a certain angle to the area where the bobbin entrance of the winding machine is located, and the yarn throwing release area 356, and then releases the bobbin and throws it into the winding station. Correspondingly, the yarn throwing area detection sensor 355 detects that the bobbin has been taken away, and the bottom support bracket 356 is lowered to a certain height under the action of the bottom support bracket cylinder 359 below, so that the empty bottom support slides along the bottom support sliding slope 358, and then falls on the bottom support recovery conveying track 310 (i.e. Fig.10 The bottom support conveyor belt 360 shown in the figure is opposite to the bobbin input conveyor belt 351 of the No. 1 yarn throwing platform 31, and is transported to the intermediate docking system 4. After the empty bottom support slides down, the bottom support bracket 356 returns to the original height, and the inlet toggle cylinder 354 is opened at this time to wait for the new bobbin to be put in.

[0061] When the tube yarn transported on the tube yarn input conveyor belt 351 does not enter the yarn throwing area of ​​the yarn throwing robot 305, it is guided by the circulating guide mechanism 306 to enter the tube yarn circulating conveyor belt 352 and is transported to the starting end of the tube yarn input conveyor belt 351. The guide cylinder robot arm 353 of another circulating guide mechanism 306 transports the tube yarn from the tube yarn circulating conveyor belt 352 back to the tube yarn input conveyor belt 351 for re-transportation.

[0062] like Fig.11 As shown in FIG. 2 , it is a schematic diagram of the structure of the yarn throwing platform No. 2 of the present invention, wherein a partial schematic diagram of the mechanism of the material taking and lifting mechanism 303 is shown in FIG. Fig.12 As shown, the material-taking and lifting mechanism 303 is provided with a docking station 330 which is connected to the tube yarn conveying platform of the No. 2 yarn-feeding platform 32.
