Description

Technical Field

[0001] This invention relates to the field of textile equipment technology, and more specifically to a combined conveying device for drawing roving. Background Technology

[0002] The spinning process mainly includes: cotton cleaning, carding, combing, drawing, roving, and spinning. The drawing process involves combining multiple raw slivers and feeding them into a drawing frame. After drafting, a finished sliver with a specified weight and length, better fiber parallelism and straightness, and a more compact structure is obtained for use in the subsequent roving process. The roving process uses a roving frame to draft the finished sliver formed in the drawing process, lengthening and thinning it into roving. Twisting is then added to enhance its strength, and the twisted roving is wound orderly onto bobbins for use in the subsequent spinning process. In both the drawing and roving processes, the drawing frame winds the drafted and combined sliver into sliver cans, while the roving frame consumes the sliver loops in the sliver cans. Therefore, there is a significant amount of empty and full sliver can transport and replacement between the drawing frame and the roving frame. Currently, the conveying and replacement of empty and full sliver cans between the drawing frame and the roving frame relies on automated conveying systems, which can save on manual labor intensity. For example, Chinese patent application 201910569104.7 discloses an intelligent spinning workshop sliver can buffering and distribution system, which sets up a sliver can conveying track and a sliver can buffering warehouse between the drawing frame and the roving frame. The system realizes the buffering and distribution of sliver cans through an automated material distribution and conveying system, and realizes flexible material conveying and distribution between the drawing process and the roving process. Moreover, the entire conveying process does not require manual intervention and realizes unmanned automated conveying. However, this system mainly realizes automated distribution and conveying through sliver can pallets, pallet conveying devices, track trolleys and sliver can gripping robots. Its structure is relatively complex and occupies a relatively large space in terms of height. Summary of the Invention

[0052] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings and specific examples.

[0053] Reference Figure 1 This embodiment provides a combined drawing frame and roving conveyor device, including: an automatic empty and full bobbin scheduling conveyor line located on the drawing frame 1 side and an automatic empty and full bobbin exchange conveyor line located on the roving frame 2 side. The automatic empty and full bobbin scheduling conveyor line and the automatic empty and full bobbin exchange conveyor line are connected to allow several empty and full bobbins to circulate between the drawing frame 1 and the roving frame 2.

[0054] Reference Figure 2 The aforementioned automatic empty / full can conveying line for the drawing frame is used to automatically schedule the empty / full cans of two drawing frames. The automatic empty / full can conveying line is arranged around the two drawing frames. The aforementioned automatic empty / full can conveying line includes an empty can feeding conveying mechanism 3, an empty can temporary storage conveying mechanism 4, and a first empty / full can rotary conveying mechanism 5-1. Two empty can feeding conveying mechanisms 3 are arranged longitudinally at the inlet side of the two drawing frames 1. One first empty / full can rotary conveying mechanism 5-1 is arranged longitudinally at the outlet side of the two drawing frames 1. Two empty can temporary storage conveying mechanisms 4 are arranged transversely between the two empty can feeding conveying mechanisms 3 and the first empty / full can rotary conveying mechanism 5-1.

[0055] Reference Figure 3The aforementioned automatic bobbin exchange conveyor line for roving frames includes a main conveyor mechanism 6-1 arranged longitudinally and several sub-conveyor mechanisms 6-2 arranged transversely. The sub-conveyor mechanisms 6-2 are arranged side by side on the side of the main conveyor mechanism 6-1 away from the drawing frame 1, and the main conveyor mechanism 6-1 is connected to the first empty and full bobbin rotary conveyor mechanism 5-1. In addition, a full bobbin pushing mechanism 10 is provided on the side of the main conveyor mechanism 6-1 away from the sub-conveyor mechanism 6-2, which is used to push the full bobbin from the main conveyor mechanism 6-1 to the corresponding sub-conveyor mechanism 6-2.

[0056] Reference Figure 4 To facilitate the connection between the automatic empty / full bobbin scheduling conveyor line on the drawing frame side and the automatic empty / full bobbin exchange conveyor line on the roving frame side, a second empty / full bobbin rotary conveyor mechanism 5-2 is provided between the first empty / full bobbin rotary conveyor mechanism 5-1 and the main roadway conveyor mechanism 6-1. The second empty / full bobbin rotary conveyor mechanism 5-2 is vertically arranged at one end of the first empty / full bobbin rotary conveyor mechanism 5-1. Furthermore, due to the connection between the automatic empty / full bobbin scheduling conveyor line on the drawing frame side and the automatic empty / full bobbin exchange conveyor line on the roving frame side... With different connection heights, a lifting mechanism 7 is provided between the second empty / full drum rotary conveyor 5-2 and the main roadway conveyor 6-1, thereby enabling the second empty / full drum rotary conveyor 5-2 to connect with the main roadway conveyor 6-1; in addition, a docking and transfer mechanism 8 is also provided on the side of the lifting mechanism 7 near the main roadway conveyor 6-1, thereby enabling the transfer of full drums between the lifting mechanism 7 and the main roadway conveyor 6-1 and the transfer of empty drums between the lifting mechanism 7 and the second empty / full drum rotary conveyor 5-2.

[0057] Reference Figure 4 To ensure the transport of empty and full skeins at the junction of the first and second empty / full skein rotary conveyor mechanisms 5-1 and 5-2, an empty skein pushing mechanism 9 is provided on the side of the second empty / full skein rotary conveyor mechanism 5-2 near the first empty / full skein rotary conveyor mechanism 5-1. The empty skein pushing mechanism 9 faces the first empty / full skein rotary conveyor mechanism 5-1 and is used to push the empty skeins transported from the second empty / full skein rotary conveyor mechanism 5-2 to the first empty / full skein rotary conveyor mechanism 5-1 and transport them to the far-end empty skein temporary storage conveyor mechanism 4 (i.e., away from the second empty / full skein rotary conveyor mechanism 5-2). If it is necessary to transport the empty skeins to the near-end empty skein temporary storage conveyor mechanism 4 (i.e., near the second empty / full skein rotary conveyor mechanism 5-2), the empty skein pushing mechanism 9 is not required. Instead, the empty skeins are directly transported to the empty skein temporary storage area by the empty skein temporary storage conveyor mechanism 4. Since the empty skein pushing mechanism 9 affects the conveying stroke of the second empty and full skein rotary conveying mechanism 5-2, when the full skein is conveyed to the docking point, the near-end empty skein temporary storage conveying mechanism 4 can push the full skein to the second empty and full skein rotary conveying mechanism 5-2.

[0058] In addition, to ensure the smooth transport of empty and full skein cans on the automatic empty / full can dispatching conveyor line of the drawing frame, the empty skein can feeding conveyor 3, the empty skein temporary storage conveyor 4, and the first empty / full can rotary conveyor 5-1 are respectively formed in the ground area between the square tube on the side of the drawing frame 1 to transport empty and full skein cans. These form an empty skein can feeding channel, an empty skein temporary storage channel (capable of storing empty skein cans), and a first empty / full can rotary conveyor channel. The ground area between one side of the second empty / full can rotary conveyor 5-2 and the square tube installed on the ground forms a second empty / full can rotary conveyor channel. The empty skein can feeding channel, the empty skein temporary storage channel, the first empty / full can rotary conveyor channel, and the second empty / full can rotary conveyor channel are interconnected. The empty skein can feeding conveyor, the empty skein temporary storage conveyor, and the first and second empty / full can rotary conveyors drive the empty and full skein cans, which are equipped with casters at the bottom, to transport in each channel.

[0059] The specific structures of the aforementioned institutions are described below.

[0060] Reference Figure 5 The aforementioned empty canister feeding and conveying mechanism 3 includes a feeding and conveying fixed plate 301, a feeding and conveying guide rail 302, a feeding and conveying hook plate 303, and a feeding and conveying drive component. The feeding and conveying hook plate 303 is arc-shaped. The feeding and conveying drive component specifically includes a feeding and conveying motor 304, two feeding and conveying pulleys, and a feeding and conveying belt 305 surrounding the two feeding and conveying pulleys. The feeding and conveying guide rail 302 and the feeding and conveying motor 304 are fixedly mounted on the feeding and conveying fixed plate 301. The two feeding and conveying pulleys are rotatably mounted at both ends of the feeding and conveying fixed plate 301 via bearing seats. The output shaft of the feeding and conveying motor 304 is fixedly connected to the shaft of one of the feeding and conveying pulleys. The feeding and conveying guide rail 302 is located on one side of the feeding and conveying belt 305. One end of the feeding and conveying hook plate 303 is fixed to the feeding and conveying belt 305 and slidably mounted above the feeding and conveying guide rail 302.

[0061] The working process of the above-mentioned empty skein can feeding conveyor is as follows: When it is necessary to transport the empty skein cans in the empty skein can storage channel to the entrance of the drawing frame, the above-mentioned feeding conveyor motor 304 drives the feeding conveyor pulley to rotate, and causes the feeding conveyor hook plate 303 (the initial position of the feeding conveyor hook plate is located at the end of the feeding conveyor guide rail away from the drawing frame, and is located on the side of the empty skein can away from the drawing frame) to slide along the feeding conveyor belt 305 along the feeding conveyor guide rail 302. Thus, the feeding conveyor hook plate 303 can push the empty skein can at the very end of the empty skein can storage channel (i.e., the empty skein can at the junction of the empty skein can storage channel and the empty skein can feeding channel) to the empty skein can feeding channel and push the empty skein can along the empty skein can feeding channel to the entrance of the drawing frame 1.

[0062] Reference Figure 6The aforementioned empty canister temporary storage and conveying mechanism 4 includes a temporary storage rotating push rod assembly and a temporary storage push-pull assembly for driving the temporary storage rotating push rod assembly to slide. The temporary storage rotating push rod assembly is located on the side close to the first empty / full canister rotary conveying mechanism. The temporary storage push-pull assembly includes a temporary storage conveying fixed frame 401, a temporary storage conveying guide rail, a temporary storage conveying slide plate 402, and a temporary storage conveying drive component, specifically a temporary storage conveying drive cylinder. The temporary storage conveying guide rail is fixedly installed below the upper crossbeam of the temporary storage conveying fixed frame 401. The temporary storage conveying slide plate 402 is slidably installed below the temporary storage conveying guide rail via at least one slider. The cylinder body of the temporary storage conveying cylinder is fixedly installed on one side of the upper crossbeam of the temporary storage conveying fixed frame 401, and one end of the piston rod of the temporary storage conveying cylinder is fixedly connected to the temporary storage conveying slide plate 402. Fixed connection; the above-mentioned temporary storage rotary push rod assembly includes a temporary storage rotary shaft 403, a temporary storage rotary push rod 404, and a temporary storage rotary motor 405. The temporary storage rotary shaft 403 is rotatably disposed below the temporary storage conveying slide plate 402 through a bearing seat, and one end of the temporary storage rotary shaft 403 is fixedly connected to the output shaft of the temporary storage rotary motor 405. The temporary storage rotary push rod 404 is vertically fixed on the temporary storage rotary shaft 403 and several are arranged along the length direction of the temporary storage rotary shaft 403. The distance between two adjacent temporary storage rotary push rods 403 is greater than the outer diameter of the empty strip tube and the full strip tube.

[0063] The working process of the above-mentioned empty skein can temporary storage and conveying mechanism is as follows: When it is necessary to temporarily store the empty skein cans (located at the junction of the first empty / full skein rotary conveyor 5-1 or the second empty / full skein rotary conveyor 5-2) transported by the first empty / full skein rotary conveyor 5-1 or the second empty / full skein rotary conveyor 5-2, the temporary storage rotary motor 405 controls the temporary storage rotary push rod 404 to move vertically downwards. The temporary storage push-pull assembly pushes the temporary storage rotary push rod assembly to move one skein distance towards the first empty / full skein rotary conveyor 5-1 or the second empty / full skein rotary conveyor 5-2. Then, the temporary storage rotary motor 405 controls the temporary storage rotary push rod 404 to rotate to a horizontal state. At this time, the empty skein can is located between the two temporary storage rotary push rods at the end. Then, the temporary storage push-pull assembly pushes the temporary storage rotary push rod assembly to move towards the draw frame inlet side. At this time, the outermost temporary storage rotary push rod of the temporary storage rotary push rod assembly pushes the empty skein can to move one skein distance along the empty skein can temporary storage channel. When empty skein cans are temporarily stored in the empty skein can storage channel, the empty skein cans that were originally in the empty skein can storage channel also move one can distance along the empty skein can storage channel toward the draw frame inlet. Finally, the temporary storage rotary motor 405 controls the temporary storage rotary push rod 404 to reset vertically downwards. In addition, when it is necessary to transport the full skein cans (the junction of the first empty full skein rotary channel and the empty skein can storage channel) from the first empty full skein rotary conveyor 5-1 to the second empty full skein rotary channel, the temporary storage rotary motor 405 of the near-end empty skein can storage conveyor controls the temporary storage rotary push rod 404 to rotate to a horizontal state. The temporary storage push-pull assembly pushes the temporary storage rotary push rod assembly toward the second empty full skein rotary channel. At this time, the temporary storage rotary push rod at the end of the temporary storage rotary push rod assembly pushes the full skein can into the second empty full skein rotary channel. Then, the temporary storage rotary push rod 404 resets vertically downwards and the temporary storage push-pull assembly drives the temporary storage rotary push rod assembly back to its original position.

[0064] Reference Figure 7Both the first empty / full drum rotary conveyor mechanism 5-1 and the second empty / full drum rotary conveyor mechanism 5-2 include an empty / full drum rotary conveyor fixing plate 501, an empty / full drum rotary conveyor drive motor 502, an empty / full drum rotary conveyor sprocket 503, an empty / full drum rotary conveyor chain 504, and an empty / full drum rotary conveyor push plate 505. Two empty / full drum rotary conveyor sprockets 503 are arranged horizontally and rotate at both ends above the empty / full drum rotary conveyor fixing plate 501. The output shaft of the empty / full drum rotary conveyor drive motor 502 is fixedly connected to the shaft of one of the empty / full drum rotary conveyor sprockets 503. The empty / full drum rotary conveyor chain 504 surrounds the two empty / full drum rotary conveyor sprockets 503. The empty / full drum rotary conveyor push plate 505 is fixed to the empty / full drum rotary conveyor chain 504, with one end extending out of the chain 504 and used to push empty and full drums. When the drive motors 502 of the first empty and full cylinder rotary conveyor mechanism 5-1 and the second empty and full cylinder rotary conveyor mechanism 5-2 rotate, they can drive the empty and full cylinder rotary conveyor push plate 505 to move along the empty and full cylinder rotary conveyor chain 504, thereby promoting the transport of empty or full cylinders in the first and second empty and full cylinder rotary channels.

[0065] Reference Figure 8 and Figure 9 The aforementioned main tunnel conveying mechanism 6-1 and sub-tunnel conveying mechanism 6-2 both include a tunnel conveying plate 601, a tunnel conveying drive motor, a tunnel conveying sprocket, a tunnel conveying chain 602, and a tunnel conveying pusher plate 603. At least two tunnel conveying sprockets are arranged along the length of the tunnel conveying plate 601 and rotate vertically below it. The output shaft of the tunnel conveying drive motor is fixedly connected to the shaft of one of the tunnel conveying sprockets. The tunnel conveying chain 602 surrounds the tunnel conveying sprocket. Several tunnel conveying pushers 603 are evenly distributed along the tunnel conveying chain. A tunnel conveying gap is provided in the middle of each tunnel conveying pusher plate 601. Each tunnel conveying pusher plate 603 extends beyond the tunnel conveying gap, and the distance between two adjacent tunnel conveying pushers 603 is greater than the outer diameter of the empty and full sprue. When the aforementioned roadway conveying drive motor rotates, it can drive the roadway conveying pusher plate to move along the roadway conveying chain, thereby pushing the empty or full strip canisters to be transported on the roadway conveying plate. During this process, the roadway conveying plate does not move.

[0066] Reference Figure 10The aforementioned full-barrel pusher mechanism 10 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. The aforementioned full-barrel pusher assembly includes a full-barrel pusher fixing seat 101, a full-barrel pusher plate 102, and a full-barrel pusher driving component. Specifically, the full-barrel pusher driving component can be a full-barrel pusher rodless cylinder 103. The full-barrel pusher rodless cylinder 103 is fixedly disposed above the full-barrel pusher fixing seat 101, and the full-barrel pusher plate 102 is fixedly disposed on the slider of the full-barrel pusher rodless cylinder 103. The aforementioned full-barrel pusher rodless cylinder 103 drives the full-barrel pusher plate 102 to push the full-barrel. The aforementioned full-strip can pusher conveying assembly includes a full-strip can pusher conveying fixing plate 104, a full-strip can pusher conveying guide rail 105, and a full-strip can pusher conveying drive component 106. Specifically, the full-strip can pusher conveying drive component is a drive component composed of a pulley, a belt, and a drive motor. The full-strip can pusher conveying guide rail 105 and the full-strip can pusher conveying drive component 106 are disposed above the full-strip can pusher conveying fixing plate 104. The full-strip can pusher fixing seat 101 is fixed on the belt of the full-strip can pusher conveying drive component 106 and slidably disposed above the full-strip can pusher conveying guide rail 105. The full-strip can pusher conveying drive component 106 can drive the full-strip can pusher fixing seat 101 to slide along the full-strip can pusher conveying guide rail 105 via the belt, that is, drive the full-strip can pusher assembly to slide along the full-strip can pusher conveying guide rail.

[0067] 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.

[0068] Reference Figure 11 The aforementioned lifting mechanism 7 includes a lifting cylinder 701 and a lifting plate 702. The lifting plate 702 is fixedly mounted on one end of the piston rod of the lifting cylinder 701. An inclined plate is provided between the second empty / full cylinder rotary conveying mechanism 5-1 and the lifting plate 702 of the lifting mechanism 7, which is used to connect the second empty / full cylinder rotary channel with the lifting plate. The second empty / full cylinder rotary conveying mechanism can push the full cylinder conveyed from the second empty / full cylinder rotary channel onto the lifting plate along the inclined plate, and then the lifting plate is raised to be flush with the roadway conveying plate of the main roadway conveying mechanism; conversely, after the empty cylinder conveyed by the main roadway conveying mechanism is conveyed onto the lifting plate, the lifting plate is lowered to be flush with one end of the inclined plate.

[0069] Reference Figure 12The aforementioned docking and transfer mechanism 8 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 the side closer to the lifting mechanism. The specific structure of the docking and transfer mechanism 8 is basically the same as that of the empty strip tube temporary storage and conveying mechanism 4. The aforementioned docking and transfer push-pull assembly includes a docking and transfer fixing frame 801, a docking and transfer guide rail 802, a docking and transfer sliding plate 803, and a docking and transfer driving component. The docking and transfer driving component specifically includes a first docking and transfer rotating motor 804, a docking and transfer gear, and a docking and transfer rack 805. The docking transfer guide rail 802 is fixedly mounted above the docking transfer fixed frame 801. The docking transfer slide plate 803 is slidably mounted above the docking transfer guide rail 802 via at least one slider. The first docking transfer rotary motor 804 is fixedly mounted above the docking transfer slide plate 803, and its output axis extends downward from the docking transfer slide plate 803 and is fixedly connected to the docking transfer gear. The docking transfer rack 805 is parallel to one side of the docking transfer guide rail 802 and meshes with the docking transfer gear. When the first docking transfer rotary motor 804 rotates, it drives the docking transfer gear to move linearly along the docking transfer rack 805, and at the same time drives the docking transfer slide plate 803 to slide along the docking transfer guide rail 802. The aforementioned docking and transfer rotary push rod assembly includes a docking and transfer rotary shaft 806, a docking and transfer rotary push rod 807, and a second docking and transfer rotary motor 808. The docking and transfer rotary shaft 806 is rotatably mounted above the docking and transfer slide plate 803 via a bearing seat, and one end of the docking and transfer rotary shaft 806 is fixedly connected to the output shaft of the second docking and transfer rotary motor 808. The docking and transfer rotary push rod 807 is vertically fixed on the docking and transfer rotary shaft 806, and two are arranged along the length of the docking and transfer rotary shaft 806. The distance between two adjacent docking and transfer rotary push rods 807 is greater than the outer diameter of the empty strip tube and the full strip tube.

[0070] The working process of the above-mentioned docking and transfer mechanism is as follows: When the full strip drum conveyed by the second empty and full drum rotary conveyor 5-2 needs to be transferred to the main roadway conveyor by the lifting mechanism, the second docking and transfer rotary motor 808 controls the docking and transfer rotary push rod 807 to move vertically upward. The docking and transfer push-pull assembly drives the docking and transfer rotary push rod assembly to move one strip drum distance towards the second empty and full drum rotary conveyor 5-2. Then the docking and transfer rotary push rod 807 rotates to a horizontal state. At this time, the full strip drum is located between the two docking and transfer rotary push rods 807. Then the docking and transfer push-pull assembly drives the docking and transfer rotary push rod assembly to move one strip drum distance towards the main roadway conveyor, that is, pushes and pulls the full strip drum on the lifting mechanism to the main roadway conveyor. Then the docking and transfer rotary push rod 807 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 conveyor to the second empty / full drum rotary conveyor 5-2 on one side of the second empty / full drum rotary conveyor, the second docking transfer rotary motor 808 controls the docking transfer rotary push rod 807 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 lifting plate. Then, the docking transfer rotary push rod 807 rotates to a horizontal state. At this time, the empty strip drum above the main roadway conveyor is located between the two horizontal docking transfer rotary push rods 807. Then, the docking transfer push-pull assembly drives the docking transfer rotary push rod assembly to move towards the lifting plate. At this time, the docking transfer... The rotating push rod 807 pushes the empty strip cylinder on the main roadway conveying mechanism to the lifting plate; then the docking transfer rotating push rod rotates vertically upward and the docking transfer push-pull assembly drives the docking transfer rotating push rod assembly to retract one empty strip cylinder distance, while the lifting plate descends to dock with the inclined plate. Then the docking transfer rotating push rod 807 rotates to the horizontal state again, the docking transfer push-pull assembly drives the docking transfer rotating push rod assembly to move forward and push the empty strip cylinder from the lifting plate to the second empty full cylinder rotary channel. Then the docking transfer rotating push rod 807 resets vertically upward and the docking transfer push-pull assembly drives the docking transfer rotating push rod assembly back to its original position.

[0071] Reference Figure 13 The aforementioned empty skein pusher mechanism 9 includes an empty skein pusher fixing frame 901, an empty skein pusher plate 902, and an empty skein pusher plate drive component. Specifically, the empty skein pusher plate drive component is an empty skein pusher drive cylinder 903. The cylinder body of the empty skein pusher drive cylinder 903 is fixed on the empty skein pusher fixing frame 901. One end of the piston rod of the empty skein pusher drive cylinder 903 is connected to the empty skein pusher plate 902. The empty skein pusher drive cylinder 903 drives the empty skein pusher plate 902 to push the empty skein.

[0072] In addition, to achieve the automated operation of the above-mentioned roving combined conveyor device, 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.

[0073] In addition, for ease of understanding, the process of changing empty and full sliver cans using the above-mentioned combined drawing roving conveyor is described.

[0074] The process of empty sliver cans being conveyed from the sub-tunnel conveyor to the drawing frame is as follows:

[0075] (a) The sub-roadway conveying mechanism transports the empty strip drum to the main roadway conveying mechanism;

[0076] (b) The main roadway conveying mechanism transports the empty strip drum to one end of the main roadway conveying mechanism near the lifting mechanism;

[0077] (c) The lifting mechanism raises the lifting plate to be level with the roadway conveying plate of the main roadway conveying mechanism, and the docking transfer mechanism pushes the empty strip cylinder from the roadway conveying plate of the main roadway conveying mechanism onto the lifting plate.

[0078] (d) The lifting mechanism lowers the lifting plate to dock with the inclined plate, and the docking and transfer mechanism pushes the empty strip cylinder from the lifting plate to the second empty full cylinder rotary channel;

[0079] (e) The second empty and full drum rotary conveyor pushes the empty drum along the second empty and full drum rotary channel to the junction (i.e., the intersection) of the first and second empty and full drum rotary channels. If it is necessary to store the empty drum in the near-end empty drum temporary storage channel, the near-end empty drum temporary storage conveyor uses the near-end empty drum temporary storage conveyor to push and pull the empty drum from the junction of the first and second empty and full drum rotary channels to the empty drum temporary storage channel. If it is necessary to store the empty drum in the far-end empty drum temporary storage channel, the empty drum pushing mechanism first pushes the empty drum to the first empty and full drum rotary channel, and then the first empty and full drum rotary conveyor pushes the empty drum along the first empty and full drum rotary channel to the junction of the first empty and full drum rotary channel and the far-end empty drum temporary storage channel. Then the far-end empty drum temporary storage conveyor pushes and pulls the empty drum from the junction to the empty drum temporary storage channel.

[0080] (f) The empty skein feeding conveyor pushes the empty skein at the very end of the empty skein temporary storage channel (i.e., the empty skein at the junction of the empty skein temporary storage channel and the empty skein feeding channel) to the empty skein feeding channel, and pushes the empty skein along the empty skein feeding channel to the entrance of the drawing machine, thus completing the empty skein feeding.

[0081] The process of conveying a fully spun sliver from a drawing frame to the sub-carriage conveyor mechanism is as follows:

[0082] (a) The drawing frame conveys the fully spun can from its outlet to the first empty can rotary passage;

[0083] (b) The first empty full cylinder rotary conveyor pushes the full strip cylinder along the first empty full cylinder rotary channel to the junction of the first and second empty full cylinder rotary channels;

[0084] (c) The near-end empty canister temporary storage and conveying mechanism pushes the full canister from the docking point of the first and second empty full canister rotary channels to the second empty full canister rotary channel. Then the second empty full canister rotary conveying mechanism pushes the full canister along the second empty full canister rotary channel to one end near the lifting mechanism and pushes the full canister onto the lifting plate of the lifting mechanism via the inclined plate.

[0085] (d) The lifting mechanism drives the lifting plate to rise to be level with the roadway conveying plate of the main roadway conveying mechanism. The docking transfer mechanism pushes the full strip cylinder from the lifting plate to the roadway conveying plate of the main roadway conveying mechanism. Then the lifting plate descends to reset and docks with the inclined plate.

[0086] (e) 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 the 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 the 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 to complete the full strip conveying.

[0087] Furthermore, the aforementioned combined roving conveyor can also be used to replace empty and full sliver cans on the roving frame without stopping the machine. In this embodiment, the roving frame has a total of 7 conveyor lines in its sub-carrier mechanism, which are labeled from top to bottom as the first to the seventh sub-carrier. The specific can replacement process is as follows:

[0088] (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.

[0089] (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.

[0090] (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.

[0091] (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.

[0092] (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.

[0093] (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.

[0094] 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.
