Description

Technical Field

[0001] This utility model relates to the field of textile equipment technology, specifically to an automatic exchange and conveying device for empty and full bobbins on a roving frame. Background Technology

[0002] The spinning process mainly includes: cotton cleaning, carding, combing, drawing, roving, and spinning. The roving process involves using a roving frame to draft the sliver formed in the drawing process, lengthening and thinning it to become roving. Twisting is then added to enhance its strength. The twisted roving is then wound onto bobbins for use in the subsequent spinning process. During roving, the roving frame continuously consumes the sliver loops in the bobbins. Once all the sliver in the bobbins is consumed, the empty bobbins must be transported to the previous drawing process for reloading, and then the full bobbins are returned to the roving frame for continued spinning. Therefore, there is a large amount of empty and full bobbin transport and replacement between roving frames. If manual replacement is used, it requires almost continuous bobbin changing, which is labor-intensive and inefficient, potentially leading to delayed bobbin replacement and reduced roving spinning efficiency. Therefore, an automatic empty and full bobbin exchange and conveying device for roving frames is proposed. Utility Model Content

[0025] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and specific examples.

[0026] Reference Figure 1 This embodiment provides an automatic exchange conveying device for empty and full bobbins on a roving frame, including: a main lane conveying mechanism 1-1 arranged longitudinally and several sub-lane conveying mechanisms 1-2 arranged laterally on one side of the main lane conveying mechanism. The several sub-lane conveying mechanisms 1-2 are arranged side by side along the length direction of the main lane conveying mechanism 1-1, and the main lane conveying mechanism 1-1 is connected to the drawing frame through an empty and full bobbin docking conveying channel 2. In addition, a full bobbin pushing mechanism 3 is provided on the side of the main lane conveying mechanism 1-1 away from the sub-lane conveying mechanisms 1-2 for pushing full bobbins from the main lane conveying mechanism 1-1 to the corresponding sub-lane conveying mechanism 1-2. A docking transfer mechanism is also provided on one side of the main lane conveying mechanism 1-1 for realizing the transfer of empty and full bobbins between the main lane conveying mechanism 1-1 and the empty and full bobbin docking conveying channel 2.

[0027] Reference Figure 2 and Figure 3The main roadway conveying mechanism 1-1 and the sub-roadway conveying mechanism 1-2 mentioned above each include a roadway conveying plate 101, a roadway conveying drive motor, a roadway conveying sprocket 104, a roadway conveying chain 102, and a roadway conveying push plate 103. The tunnel conveyor pusher plate 101 is formed by splicing two flat plates with a tunnel conveying gap between them. Multiple tunnel conveyor sprockets 104 are arranged along the length of the tunnel conveyor plate 101 and rotate vertically below the tunnel conveyor plate 101. The output shaft of the tunnel conveying drive motor is fixedly connected to the shaft of one of the tunnel conveyor sprockets 104. The tunnel conveying chain 102 is arranged around the multiple tunnel conveyor sprockets 104, and the middle tunnel conveyor sprocket 104 supports the tunnel conveying chain 102. Several tunnel conveyor pushers 103 are arranged and evenly distributed along the tunnel conveying chain. A tunnel conveying gap is provided in the middle of the tunnel conveyor pusher plate 101. The tunnel conveyor pusher plate 103 extends out of the tunnel conveying gap, and the distance between two adjacent tunnel conveyor pushers 103 is greater than the outer diameter of the empty and full sprockets. When the aforementioned roadway conveying drive motor rotates, it can drive the roadway conveying push plate to follow the roadway conveying chain, thereby pushing the empty or full strip cans to be transported on the roadway conveying plate, and the roadway conveying plate does not move during this process.

[0028] Reference Figure 4 The aforementioned full-barrel pusher mechanism 3 includes a full-barrel pusher assembly for pushing full-barrels from the main roadway conveying mechanism to the sub-roadway conveying mechanism, and a full-barrel pusher conveying assembly for driving the full-barrel pusher assembly to slide along the length direction of the main roadway conveying mechanism. Specifically, the full-barrel pusher assembly includes a full-barrel pusher fixing seat 301, a full-barrel pusher plate 302, and a full-barrel pusher driving component. The full-barrel pusher driving component can specifically be a full-barrel pusher rodless cylinder 303, which is fixedly mounted above the full-barrel pusher fixing seat 301, and the full-barrel pusher plate 302 is fixedly mounted on the slider of the full-barrel pusher rodless cylinder 303. The full-barrel pusher rodless cylinder 303 drives the full-barrel pusher plate 302 to push the full-barrel. The aforementioned full-strip drum pusher conveying assembly includes a full-strip drum pusher conveying fixing plate 304, a full-strip drum pusher conveying guide rail 305, and a full-strip drum pusher conveying drive component 306. Specifically, the full-strip drum pusher conveying drive component is a drive component composed of a pulley, a belt, and a drive motor. The full-strip drum pusher conveying guide rail 305 and the full-strip drum pusher conveying drive component 306 are disposed above the full-strip drum pusher conveying fixing plate 304. The full-strip drum pusher fixing seat 301 is fixed on the belt of the full-strip drum pusher conveying drive component 306 and slidably disposed above the full-strip drum pusher conveying guide rail 305. The full-strip drum pusher conveying drive component 306 can drive the full-strip drum pusher fixing seat 301 to slide along the full-strip drum pusher conveying guide rail 305 via the belt, that is, drive the full-strip drum pusher assembly to slide along the full-strip drum pusher conveying guide rail.

[0029] The working process of the above-mentioned full-bar pusher mechanism is as follows: the full-bar pusher conveying assembly first drives the full-bar pusher assembly to slide to the sub-way conveying mechanism that needs to be filled with full-bars, and at this time, the rodless cylinder of the full-bar pusher assembly can block and position the conveyed full-bars. When the full-bars are conveyed to the sub-way conveying mechanism that needs to be filled with full-bars, the conveying stops. Then, the full-bar pusher plate of the full-bar pusher assembly pushes the full-bars from the main roadway conveying mechanism to the sub-way conveying mechanism.

[0030] Reference Figure 5 The aforementioned docking and transfer mechanism 4 includes a docking and transfer rotating push rod assembly and a docking and transfer push-pull assembly for driving the docking and transfer rotating push rod assembly to slide. The docking and transfer rotating push rod assembly is located on one side close to the empty and full cylinder docking and conveying channel. The specific structure of the docking and transfer mechanism 4 is basically the same as that of the empty bar cylinder temporary storage and conveying mechanism 4. The aforementioned docking and transfer push-pull assembly includes a docking and transfer fixing frame 401, a docking and transfer guide rail 402, a docking and transfer sliding plate 403, and a docking and transfer drive component. The docking and transfer drive component specifically includes a first docking and transfer rotary motor 404, a docking and transfer gear, and a docking and transfer rack 405. The docking and transfer guide rail 402 is fixedly mounted above the docking and transfer fixing frame 401. The docking and transfer sliding plate 403 is slidably mounted above the docking and transfer guide rail 402 via at least one slider. The first docking and transfer rotary motor 404 is fixedly mounted above the docking and transfer sliding plate 403, with its output axis extending downwards from the docking and transfer sliding plate 403 and fixedly connected to the docking and transfer gear. The docking and transfer rack 405 is parallel to one side of the docking and transfer guide rail 402 and meshes with the docking and transfer gear. When the first docking and transfer rotary motor 404 rotates, it drives the docking and transfer gear to move linearly along the docking and transfer rack 405, and simultaneously drives the docking and transfer sliding plate 403 to slide along the docking and transfer guide rail 402. The aforementioned docking and transfer rotary push rod assembly includes a docking and transfer rotary shaft 406, a docking and transfer rotary push rod 407, and a second docking and transfer rotary motor 408. The docking and transfer rotary shaft 406 is rotatably mounted above the docking and transfer slide plate 403 via a bearing seat, and one end of the docking and transfer rotary shaft 406 is fixedly connected to the output shaft of the second docking and transfer rotary motor 408. The docking and transfer rotary push rod 407 is vertically fixed on the docking and transfer rotary shaft 406, and two are arranged along the length of the docking and transfer rotary shaft 406. The distance between two adjacent docking and transfer rotary push rods 407 is greater than the outer diameter of the empty strip tube and the full strip tube.

[0031] The working process of the above-mentioned docking and transfer mechanism is as follows: When it is necessary to transfer the full sliver produced by the drawing machine from the empty and full sliver docking and conveying channel 2 to the main roadway conveying mechanism 1-1, the second docking and transfer rotary motor 408 controls the docking and transfer rotary push rod 407 to move vertically upward. The docking and transfer push-pull assembly drives the docking and transfer rotary push rod assembly to move one full sliver distance towards the empty and full sliver docking and conveying channel. Then, the docking and transfer rotary push rod 407 rotates to a horizontal state. At this time, the full sliver is located between the two docking and transfer rotary push rods 407. Then, the docking and transfer push-pull assembly drives the docking and transfer rotary push rod assembly to move one sliver distance towards the main roadway conveying mechanism, that is, push and pull the full sliver on the empty and full sliver docking and conveying channel to the main roadway conveying mechanism. Then, the docking and transfer rotary push rod 407 returns to its vertical position and the docking and transfer push-pull assembly drives the docking and transfer rotary push rod assembly back to its original position. When it is necessary to transfer the empty strip drum on the main roadway conveying mechanism to the empty / full drum docking conveying channel, the second docking transfer rotary motor 408 controls the docking transfer rotary push rod 407 to move vertically upward. The docking transfer push-pull assembly drives the docking transfer rotary push rod assembly to move one empty strip drum distance towards the empty / full drum docking conveying channel. Then, the docking transfer rotary push rod 407 rotates to a horizontal state. At this time, the empty strip drum is located between the two horizontal docking transfer rotary push rods 407. Next, the docking transfer push-pull assembly drives the docking transfer rotary push rod assembly to move towards the empty / full drum docking conveying channel. At this time, the docking transfer rotary push rod 407 pushes the empty strip drum on the main roadway conveying mechanism to the empty / full drum docking conveying channel. Then, the docking transfer rotary push rod rotates to a vertically upward reset position, and the docking transfer push-pull assembly drives the docking transfer rotary push rod assembly to return to its original position.

[0032] In addition, to achieve the automated operation of the above-mentioned automatic bobbin exchange conveying device for roving frames, the device also includes a control cabinet, and the control cabinet is equipped with a PLC control system that is connected to the above-mentioned mechanisms. By setting the corresponding control program in the PLC control system, the mechanisms can automatically cooperate to execute the corresponding action commands.

[0033] In this embodiment, the roving frame has seven sub-carrier conveyor lines, which are labeled as sub-carriers one through seven from top to bottom. The aforementioned automatic empty / full bobbin exchange conveyor device enables automatic exchange of empty and full bobbins on the roving frame, achieving bobbin changing without stopping the machine. The specific process is as follows:

[0034] (1) During the laying stage, first lay 5 / 5 full slivers, 4 / 5 full slivers, 3 / 5 full slivers, 2 / 5 full slivers and 1 / 5 full slivers respectively in the first to fifth sub-lanes. The sixth sub-lane is empty, and the seventh sub-lane is laid with 5 / 5 full slivers. The first to fifth sub-lanes are used as spinning lanes, and the seventh sub-lane is used as a spare lane.

[0035] (2) When the roving frame is started to spin, when 1 / 5 of the sliver in each can is consumed, the sliver in the fifth sub-carriage can is completely consumed and becomes an empty can. At this time, there is no need to stop the machine. The operator can stand directly on the conveyor plate of the sixth sub-carriage conveyor mechanism to splice the sliver in the spare full can of the seventh sub-carriage and use it as the spinning lane. At the same time, the empty cans of the fifth sub-carriage are sequentially conveyed to the drawing frame. Then the drawing frame spins the empty cans into full cans and conveys the full cans to the sixth sub-carriage as a spare lane. The fifth sub-carriage is idle. It should be noted that during this process, the number of empty cans in the temporary storage channels on both sides of the drawing frame is usually less than the number of empty cans in the fifth sub-carriage. Therefore, some empty cans can be conveyed and temporarily stored in the empty can storage channel first. Then the drawing frame spins the conveyed empty cans into full cans and conveys them to the sixth sub-carriage. Repeat this process until all the empty cans in the fifth sub-carriage are spun into full cans and conveyed to the sixth sub-carriage.

[0036] (4) When 1 / 5 of the sliver is consumed again in the sliver can, the sliver in the fourth sub-carriage can is completely consumed and becomes an empty sliver can. At this time, there is no need to stop the machine. The operator can stand directly on the conveyor plate of the fifth sub-carriage conveyor mechanism to connect the sliver in the spare full sliver can of the sixth sub-carriage and use it as the spinning can. At the same time, the empty sliver cans of the fourth sub-carriage are sequentially conveyed to the drawing frame. Then the drawing frame spins the empty sliver cans into full sliver cans and conveys the full sliver cans to the fifth sub-carriage as a spare can. The fourth sub-carriage is idle.

[0037] (5) When 1 / 5 of the sliver is consumed again in the sliver can, the sliver in the sliver can of the third sub-carriage is completely consumed and becomes an empty sliver can. At this time, there is no need to stop the machine. The operator can stand directly on the conveyor plate of the conveyor mechanism of the fourth sub-carriage to splice the sliver in the spare full sliver can of the fifth sub-carriage and use it as the spinning can. At the same time, the empty sliver cans of the sliver cans of the third sub-carriage are sequentially conveyed to the drawing frame. Then the drawing frame spins the empty sliver cans into full sliver cans and conveys the full sliver cans to the fourth sub-carriage as a spare can. The third sub-carriage is idle.

[0038] (6) When 1 / 5 of the sliver is consumed again in the sliver can, the sliver in the second sub-carriage is completely consumed and becomes an empty sliver can. At this time, there is no need to stop the machine. The operator can stand directly on the conveyor plate of the conveyor mechanism of the third sub-carriage to splice the sliver in the spare full sliver can of the fourth sub-carriage and use it as the spinning can. At the same time, the empty sliver cans of the second sub-carriage are sequentially conveyed to the drawing frame. Then the drawing frame spins the empty sliver cans into full sliver cans and conveys the full sliver cans to the third sub-carriage as a spare can. The second sub-carriage is idle.

[0039] (7) When 1 / 5 of the sliver is consumed again in the sliver can, the sliver in the first sub-carriage is completely consumed and becomes an empty sliver can. At this time, there is no need to stop the machine. The operator can stand directly on the conveyor plate of the conveyor mechanism of the second sub-carriage to connect the sliver in the spare full sliver can of the third sub-carriage and use it as the spinning can. At the same time, the empty sliver cans of the first sub-carriage are sequentially conveyed to the drawing frame. Then the drawing frame spins the empty sliver cans into full sliver cans and conveys the full sliver cans to the second sub-carriage as a spare can. The first sub-carriage is idle.

[0040] This process is repeated to complete the replacement of empty and full sliver cans on the roving frame. During this process, it is not necessary to stop the frame to change the cans. It is only necessary to pause the roving frame winding mechanism in the corresponding sub-carriage when splicing after the can change.

[0041] In addition, for ease of understanding, the process of changing empty and full sliver cans by the above-mentioned automatic empty and full sliver can exchange conveying device for roving frame is described.

[0042] The process of transporting empty skein cans from the sub-tunnel conveyor to the empty / full skein docking conveyor channel that connects with the drawing frame is as follows:

[0043] (a) The sub-roadway conveying mechanism transports the empty strip drum to the main roadway conveying mechanism;

[0044] (b) The main roadway conveying mechanism transports the empty strip drum to one end of the main roadway conveying mechanism near the empty / full drum docking conveying channel;

[0045] (c) The docking and transfer mechanism pushes the empty bar canister from the main roadway conveying mechanism roadway conveying plate to the empty and full bar canister docking and transfer channel to complete the empty bar canister transfer.

[0046] The process of a fully spun sliver from a drawing frame being conveyed to a sub-carrying conveyor via an empty / full can docking conveyor channel is as follows:

[0047] (a) The docking and transfer mechanism pushes the full strip can from the empty and full strip docking and conveying channel to the main roadway conveying mechanism roadway conveying plate;

[0048] (b) The full-strip pusher conveying assembly of the full-strip pusher mechanism first drives the full-strip pusher assembly to slide to the position of the sub-way conveying mechanism that needs to be filled with full-strip for positioning. Then, the roadway conveying pusher plate of the main roadway conveying mechanism moves and pushes the full-strip to the sub-way conveying mechanism that needs to be filled with full-strip, and stops conveying. Then, the full-strip pusher assembly pushes the full-strip from the roadway conveying plate of the main roadway conveying mechanism to the roadway conveying plate of the sub-way conveying mechanism, thus completing the full-strip conveying.

[0049] It should be noted that any parts not mentioned in this utility model can be achieved by adopting or referencing existing technologies.

[0050] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
