[0002] The spinning process mainly includes: bale opening, carding, combing, drawing, roving, spinning, etc. Among them, in the drawing process, multiple slivers are combined and fed into a drawing frame, and through drafting, a sliver with a specified weight and a certain length is obtained, and the fibers are more parallel and straightened, and the structure is more compact, for use in the subsequent roving process; in the roving process, the sliver formed in the drawing process is drafted by a roving frame, stretched and thinned, transformed into roving, and twisted to enhance its strength, and then the twisted roving is wound on a bobbin in an orderly manner for use in the subsequent spinning process. In the drawing and roving processes, the drawing frame winds the drawn and combined sliver into a sliver can, while the roving frame consumes the sliver in the sliver can, so there is a large amount of empty sliver cans, full sliver cans for conveying and replacement between the drawing frame and the roving frame. At present, the conveying and replacement of empty sliver cans and full sliver cans between the drawing frame and the roving frame rely on an automated conveying system, which can save the labor intensity of workers. For example, Chinese Patent Application No. 201910569104.7 discloses an intelligent spinning workshop sliver can caching and distribution system, which sets a sliver can conveying track and a sliver can cache library between the drawing frame and the roving frame, and realizes the caching and distribution conveying 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, and the entire conveying process does not require manual intervention, realizing unmanned automated conveying; however, this system mainly realizes automated distribution and conveying through sliver can trays, tray conveying devices, rail trolleys and sliver can grabbing robots, its structure is relatively complex, and it occupies a relatively large space in height.

[0052] The following further describes the specific embodiments of the present invention in conjunction with the accompanying drawings and specific embodiments.

[0053] Refer to Figure 1 , this embodiment provides a drawing frame and roving combined conveying device, including: a drawing frame empty and full bobbin automatic scheduling and conveying line located on the side of the drawing frame 1 and a roving frame empty and full bobbin automatic exchange and conveying line located on the side of the roving frame 2. The drawing frame empty and full bobbin automatic scheduling and conveying line is connected to the roving frame empty and full bobbin automatic exchange and conveying line for several empty bobbins and full bobbins to circulate between the drawing frame 1 and the roving frame 2.

[0054] Refer to Figure 2 , the above-mentioned drawing frame empty and full bobbin automatic scheduling and conveying line is used to realize the automatic scheduling of empty and full bobbins of two drawing frames, and the drawing frame empty and full bobbin automatic scheduling and conveying line is arranged around the two drawing frames. The above-mentioned drawing frame empty and full bobbin automatic scheduling and conveying line includes an empty bobbin feeding conveying mechanism 3, an empty bobbin temporary storage conveying mechanism 4, and a first empty and full bobbin rotary conveying mechanism 5-1; two empty bobbin feeding conveying mechanisms 3 are provided and are respectively arranged longitudinally on the inlet sides of the two drawing frames 1, one first empty and full bobbin rotary conveying mechanism 5-1 is provided and is arranged longitudinally on the outlet sides of the two drawing frames 1, and two empty bobbin temporary storage conveying mechanisms 4 are provided and are respectively arranged transversely between the two empty bobbin feeding conveying mechanisms 3 and the first empty and full bobbin rotary conveying mechanism 5-1.

[0055] Refer to Figure 3, the above-mentioned automatic empty / full bobbin exchange and conveying line of the roving frame includes a main lane conveying mechanism 6-1 arranged longitudinally and several sub-lane conveying mechanisms 6-2 arranged transversely. The several sub-lane conveying mechanisms 6-2 are arranged side by side on the side of the main lane conveying mechanism 6-1 away from the drawing frame 1, and the main lane conveying mechanism 6-1 is docked with the first empty / full bobbin rotary conveying mechanism 5-1. In addition, a full bobbin pushing mechanism 10 is arranged on the side of the main lane conveying mechanism 6-1 away from the sub-lane conveying mechanisms 6-2 and is used to push the full bobbin from the main lane conveying mechanism 6-1 to the corresponding sub-lane conveying mechanism 6-2.

[0056] Refer to Figure 4 , to facilitate the docking of the automatic empty / full bobbin scheduling and conveying line on the side of the drawing frame and the automatic empty / full bobbin exchange and conveying line on the side of the roving frame, a second empty / full bobbin rotary conveying mechanism 5-2 is arranged between the first empty / full bobbin rotary conveying mechanism 5-1 and the main lane conveying mechanism 6-1. The second empty / full bobbin rotary conveying mechanism 5-2 is vertically arranged at one end of the first empty / full bobbin rotary conveying mechanism 5-1. And because the heights of the docking points of the automatic empty / full bobbin scheduling and conveying line of the drawing frame and the automatic empty / full bobbin exchange and conveying line on the side of the roving frame are different, a lifting mechanism 7 is arranged between the second empty / full bobbin rotary conveying mechanism 5-2 and the main lane conveying mechanism, so as to realize the docking of the second empty / full bobbin rotary conveying mechanism 5-2 and the main lane conveying mechanism 6-1. In addition, a docking and transfer mechanism 8 is also arranged on the side of the lifting mechanism 7 close to the main lane conveying mechanism 6-1, so as to realize the transfer of the full bobbin between the lifting mechanism 7 and the main lane conveying mechanism 6-1 and the transfer of the empty bobbin between the lifting mechanism 7 and the second empty / full bobbin rotary conveying mechanism 5-2.

[0057] Refer to Figure 4 , to ensure the conveying of the empty bobbin and the full bobbin at the docking point between the first empty / full bobbin rotary conveying mechanism 5-1 and the second empty / full bobbin rotary conveying mechanism 5-2, an empty bobbin pushing cylinder mechanism 9 is arranged on the side surface of one end of the second empty / full bobbin rotary conveying mechanism 5-2 close to the first empty / full bobbin rotary conveying mechanism 5-1, and the empty bobbin pushing cylinder mechanism 9 faces the first empty / full bobbin rotary conveying mechanism 5-1 and is used to push the empty bobbin conveyed by the second empty / full bobbin rotary conveying mechanism 5-2 to the first empty / full bobbin rotary conveying mechanism 5-1 and convey it to the empty bobbin temporary storage and conveying mechanism 4 at the far end (that is, away from the second empty / full bobbin rotary conveying mechanism 5-2); if it is necessary to convey the empty bobbin to the empty bobbin temporary storage and conveying mechanism 4 at the near end (that is, close to the second empty / full bobbin rotary conveying mechanism 5-2), the empty bobbin pushing cylinder mechanism 9 is not required, but the empty bobbin temporary storage and conveying mechanism 4 directly conveys the empty bobbin to the empty bobbin temporary storage area. Since the above-mentioned empty bobbin pushing cylinder mechanism 9 affects the conveying stroke of the second empty / full bobbin rotary conveying mechanism 5-2, when the full bobbin is conveyed to this docking point, the empty bobbin temporary storage and conveying mechanism 4 at the near end can push the full bobbin to the second empty / full bobbin rotary conveying mechanism 5-2.

[0058] In addition, to ensure the smooth transportation of empty and full cans on the automatic scheduling and conveying line of empty and full cans of the above draw frame, the ground areas between the above-mentioned empty can feeding conveying mechanism 3, empty can temporary storage conveying mechanism 4, and the first empty / full can rotary conveying mechanism 5-1 and the square pipe on the side of the draw frame 1 respectively form an empty can feeding channel, an empty can temporary storage channel (capable of storing empty cans), and a first empty / full can rotary channel for the transportation of empty and full cans. The ground area between one side of the above-mentioned second empty / full can rotary conveying mechanism 5-2 and the square pipe installed on the ground forms a second empty / full can rotary channel, and the empty can feeding channel, the empty can temporary storage channel, the first empty / full can rotary channel, and the second empty / full can rotary channel are connected to each other; the above-mentioned empty can feeding conveying mechanism, empty can temporary storage conveying mechanism, and the first and second empty / full can rotary conveying mechanisms drive the empty cans and full cans with universal wheels at the bottom to be transported in each channel.

[0059] The specific structures of the above-mentioned mechanisms are described as follows.

[0060] Referring to Figure 5 , the above-mentioned empty can feeding conveying mechanism 3 includes a feeding conveying fixing plate 301, a feeding conveying guide rail 302, a feeding conveying hook plate 303, and a feeding conveying driving member. The feeding conveying hook plate 303 is arc-shaped, and the feeding conveying driving member specifically includes a feeding conveying motor 304, two feeding conveying belt wheels, and a feeding conveying belt 305 surrounding the two feeding conveying belt wheels. Among them, the feeding conveying guide rail 302 and the feeding conveying motor 304 are fixedly arranged on the feeding conveying fixing plate 301. The two feeding conveying belt wheels are rotatably arranged at both ends of the feeding conveying fixing plate 301 through bearing seats, and the output shaft of the feeding conveying motor 304 is fixedly connected to the rotating shaft of one of the feeding conveying belt wheels; the feeding conveying guide rail 302 is located on one side of the feeding conveying belt 305, and one end of the feeding conveying hook plate 303 is fixed on the feeding conveying belt 305 and is slidably arranged above the feeding conveying guide rail 302.

[0061] The working process of the above-mentioned empty can feeding conveying mechanism is as follows: When it is necessary to transport the empty cans in the empty can temporary storage channel to the entrance of the draw frame, the above-mentioned feeding conveying motor 304 drives the feeding conveying belt wheels to rotate, and the feeding conveying hook plate 303 (the initial position of the feeding conveying hook plate is at the end of the feeding conveying guide rail far from the draw frame and on the side of the empty can far from the draw frame) follows the feeding conveying belt 305 to slide along the feeding conveying guide rail 302, so that the feeding conveying hook plate 303 can push the empty can at the outermost end of the empty can temporary storage channel (i.e., the empty can at the docking position of the empty can temporary storage channel and the empty can feeding channel) to the empty can feeding channel and push the empty can along the empty can feeding channel to the entrance of the draw frame 1.

[0062] Referring to Figure 6, the above-mentioned empty bobbin temporary storage and conveying mechanism 4 includes a temporary storage rotating push rod assembly and a temporary storage push-pull assembly for driving the sliding of the temporary storage rotating push rod assembly, and the temporary storage rotating push rod assembly is located on the side close to the first empty / full bobbin rotary conveying mechanism. Among them, the above-mentioned 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 driving member. The temporary storage conveying driving member is specifically a temporary storage conveying driving cylinder; the temporary storage conveying guide rail is fixedly arranged under the upper cross beam of the temporary storage conveying fixed frame 401, the temporary storage conveying slide plate 402 is slidably arranged under the temporary storage conveying guide rail through at least one slider, the cylinder body of the temporary storage conveying cylinder is fixedly arranged on one side of the upper cross beam of the temporary storage conveying fixed frame 401 and one end of the piston rod of the temporary storage conveying cylinder is fixedly connected with the temporary storage conveying slide plate 402; the above-mentioned temporary storage rotating push rod assembly includes a temporary storage rotating shaft 403, a temporary storage rotating push rod 404 and a temporary storage rotating motor 405. The temporary storage rotating shaft 403 is rotatably arranged under the temporary storage conveying slide plate 402 through a bearing seat and one end of the temporary storage rotating shaft 403 is fixedly connected with the output shaft of the temporary storage rotating motor 405. The temporary storage rotating push rod 404 is vertically fixed on the temporary storage rotating shaft 403 and a plurality of them are arranged along the length direction of the temporary storage rotating shaft 403. The distance between two adjacent temporary storage rotating push rods 403 is greater than the outer diameters of the empty bobbins and full bobbins.

[0063] The working process of the above-mentioned empty bobbin temporary storage and conveying mechanism is as follows: When it is necessary to temporarily store the empty bobbins conveyed by the first empty / full bobbin rotary conveying mechanism 5-1 or the second empty / full bobbin rotary conveying mechanism 5-2 (located at the docking position of the first empty / full bobbin rotary channel or the second empty / full bobbin rotary channel and the empty bobbin temporary storage channel), the temporary storage rotation motor 405 controls the temporary storage rotation push rod 404 to move vertically downward, and the temporary storage push-pull assembly pushes the temporary storage rotation push rod assembly to move a bobbin distance in the direction of the first empty / full bobbin rotary conveying mechanism 5-1 or the second empty / full bobbin rotary conveying mechanism 5-2. Then, the temporary storage rotation motor 405 controls the temporary storage rotation push rod 404 to rotate to the horizontal state. At this time, the empty bobbin is located between the two temporary storage rotation push rods at the end. Next, the temporary storage push-pull assembly pushes the temporary storage rotation push rod assembly to move in the direction of the drawing frame inlet side. At this time, the outermost temporary storage rotation push rod of the temporary storage rotation push rod assembly pushes the empty bobbin to move a bobbin distance along the empty bobbin temporary storage channel. The empty bobbin is temporarily stored in the empty bobbin temporary storage channel, and the empty bobbins originally existing in the empty bobbin temporary storage channel also move a bobbin distance along the empty bobbin temporary storage channel in the direction of the drawing frame inlet. Finally, the temporary storage rotation motor 405 controls the temporary storage rotation push rod 404 to return vertically downward; in addition, when it is necessary to convey the full bobbin (at the docking position of the first empty / full bobbin rotary channel and the empty bobbin temporary storage channel) conveyed by the first empty / full bobbin rotary conveying mechanism 5-1 to the second empty / full bobbin rotary channel, the temporary storage rotation motor 405 of the proximal empty bobbin temporary storage and conveying mechanism controls the temporary storage rotation push rod 404 to rotate to the horizontal state, and the temporary storage push-pull assembly pushes the temporary storage rotation push rod assembly to move in the direction of the second empty / full bobbin rotary channel. At this time, the temporary storage rotation push rod at the end of the temporary storage rotation push rod assembly pushes the full bobbin into the second empty / full bobbin rotary channel. Then, the temporary storage rotation push rod 404 returns vertically downward and the temporary storage push-pull assembly drives the temporary storage rotation push rod assembly to return to the original position.

[0064] Refer to Figure 7, both the first empty / full bobbin rotary conveying mechanism 5-1 and the second empty / full bobbin rotary conveying mechanism 5-2 include an empty / full bobbin rotary conveying fixed plate 501, an empty / full bobbin rotary conveying drive motor 502, an empty / full bobbin rotary conveying sprocket 503, an empty / full bobbin rotary conveying chain 504, and an empty / full bobbin rotary conveying push plate 505. Among them, two empty / full bobbin rotary conveying sprockets 503 are provided and are rotatably arranged at both ends above the empty / full bobbin rotary conveying fixed plate 501 in the horizontal direction. The output shaft of the empty / full bobbin rotary conveying drive motor 502 is fixedly connected to the rotating shaft of one of the empty / full bobbin rotary conveying sprockets 503. The empty / full bobbin rotary conveying chain 504 is arranged to surround the two empty / full bobbin rotary conveying sprockets 503. The empty / full bobbin rotary conveying push plate 505 is fixed to the empty / full bobbin rotary conveying chain 504, and one end thereof extends outside the empty / full bobbin rotary conveying chain 504 and is used to push empty bobbins and full bobbins. When the empty / full bobbin rotary conveying drive motors 502 of the first empty / full bobbin rotary conveying mechanism 5-1 and the second empty / full bobbin rotary conveying mechanism 5-2 rotate, they can drive the empty / full bobbin rotary conveying push plates 505 to move along with the empty / full bobbin rotary conveying chains 504, thereby pushing the empty bobbins or full bobbins to be transported in the first and second empty / full bobbin rotary channels.

[0065] Refer to Figure 8 and Figure 9 , both the main roadway conveying mechanism 6-1 and the sub-roadway conveying mechanism 6-2 include a roadway conveying plate 601, a roadway conveying drive motor, roadway conveying sprockets, a roadway conveying chain 602, and a roadway conveying push plate 603. Among them, at least two roadway conveying sprockets are arranged along the length direction of the roadway conveying plate 601 and are rotatably arranged below the roadway conveying plate 601 in the vertical direction. The output shaft of the roadway conveying drive motor is fixedly connected to the rotating shaft of one of the roadway conveying sprockets. The roadway conveying chain 602 is arranged to surround the roadway conveying sprockets. A number of roadway conveying push plates 603 are provided, and the number of roadway conveying push plates 603 is evenly distributed along the roadway conveying chain. A roadway conveying gap is provided in the middle of the roadway conveying push plate 601, and the roadway conveying push plate 603 extends outside the roadway conveying gap. The distance between two adjacent roadway conveying push plates 603 is greater than the outer diameters of the empty bobbins and full bobbins. When the roadway conveying drive motor rotates, it can drive the roadway conveying push plates to move along the roadway conveying chain, thereby pushing the empty bobbins or full bobbins to be transported on the roadway conveying plate, and the roadway conveying plate does not move during this process.

[0066] Refer to Figure 10, the above-mentioned full bobbin pushing mechanism 10 includes a full bobbin pushing component for pushing a full bobbin from the main roadway conveying mechanism to the sub-roadway conveying mechanism, and a full bobbin pushing and conveying component for driving the full bobbin pushing component to slide along the length direction of the main roadway conveying mechanism. The above-mentioned full bobbin pushing component includes a full bobbin pushing fixed seat 101, a full bobbin pushing plate 102 and a full bobbin pushing driving member. The full bobbin pushing driving member can specifically adopt a full bobbin pushing rodless cylinder 103. The full bobbin pushing rodless cylinder 103 is fixedly arranged above the full bobbin pushing fixed seat 101, and the full bobbin pushing plate 102 is fixedly arranged on the slider of the full bobbin pushing rodless cylinder 103; the above-mentioned full bobbin pushing rodless cylinder 103 drives the full bobbin pushing plate 102 to push the full bobbin. The above-mentioned full bobbin pushing and conveying component includes a full bobbin pushing and conveying fixed plate 104, a full bobbin pushing and conveying guide rail 105 and a full bobbin pushing and conveying driving member 106, and the full bobbin pushing and conveying driving member specifically adopts a driving member composed of a pulley, a belt and a driving motor; the above-mentioned full bobbin pushing and conveying guide rail 105 and the full bobbin pushing and conveying driving member 106 are arranged above the full bobbin pushing and conveying fixed plate 104. The above-mentioned full bobbin pushing fixed seat 101 is fixed on the belt of the full bobbin pushing and conveying driving member 106 and is slidably arranged above the full bobbin pushing and conveying guide rail 105. The above-mentioned full bobbin pushing and conveying driving member 106 can drive the full bobbin pushing fixed seat 101 to slide along the full bobbin pushing and conveying guide rail 105 through the belt, that is, drive the full bobbin pushing component to slide along the full bobbin pushing and conveying guide rail.

[0067] The working process of the above-mentioned full bobbin pushing mechanism is as follows: the full bobbin pushing and conveying component first drives the full bobbin pushing component to slide to the sub-roadway conveying mechanism that needs a full bobbin. At this time, the full bobbin pushing rodless cylinder of the full bobbin pushing component can block and position the conveyed full bobbin. When the full bobbin is conveyed to the sub-roadway conveying mechanism that needs a full bobbin, the conveying stops. Then, the full bobbin pushing plate of the full bobbin pushing component pushes the full bobbin from the main roadway conveying mechanism to the sub-roadway conveying mechanism.

[0068] Refer to Figure 11 , the above-mentioned lifting mechanism 7 includes a lifting cylinder 701 and a lifting plate 702. The lifting plate 702 is fixedly arranged at one end of the piston rod of the lifting cylinder 701. An inclined plate is arranged between the second empty and full bobbin rotary conveying mechanism 5-1 and the lifting plate 702 of the lifting mechanism 7 and is used to dock the second empty and full bobbin rotary channel with the lifting plate. The second empty and full bobbin rotary conveying mechanism can push the full bobbin conveyed from the second empty and full bobbin rotary channel to the lifting plate along the inclined plate, and then the lifting plate is lifted to be flush with the roadway conveying plate of the main roadway conveying mechanism; conversely, after the empty bobbin conveyed by the main roadway conveying mechanism is conveyed to the lifting plate, the lifting plate descends to be flush with one end of the inclined plate.

[0069] Refer to Figure 12, the above-mentioned docking and transfer mechanism 8 includes a docking and transfer rotary push rod assembly and a docking and transfer push-pull assembly for driving the sliding of the docking and transfer rotary push rod assembly, and the docking and transfer rotary push rod assembly is located on the side close to the lifting mechanism. The specific structure of the docking and transfer mechanism 8 is basically the same as that of the empty bobbin temporary storage and conveying mechanism 4. The above-mentioned docking and transfer push-pull assembly includes a docking and transfer fixed frame 801, a docking and transfer guide rail 802, a docking and transfer slide plate 803 and a docking and transfer driving member. The docking and transfer driving member specifically includes a first docking and transfer rotary motor 804, a docking and transfer gear and a docking and transfer rack 805. Among them, the docking and transfer guide rail 802 is fixedly arranged above the docking and transfer fixed frame 801, the docking and transfer slide plate 803 is slidably arranged above the docking and transfer guide rail 802 through at least one slider, the first docking and transfer rotary motor 804 is fixedly arranged above the docking and transfer slide plate 803 and its output shaft extends downward out of the docking and transfer slide plate 803 and is fixedly connected with the docking and transfer gear, the docking and transfer rack 805 is arranged in parallel on one side of the docking and transfer guide rail 802 and meshes with the docking and transfer gear. When the first docking and transfer rotary motor 804 rotates, it drives the docking and transfer gear to move linearly along the docking and transfer rack 805, and at the same time drives the docking and transfer slide plate 803 to slide along the docking and transfer guide rail 802. The above-mentioned 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. Among them, the docking and transfer rotary shaft 806 is rotatably arranged above the docking and transfer slide plate 803 through a bearing seat, and one end of the docking and transfer rotary shaft 806 is fixedly connected with 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 direction 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 diameters of the empty bobbin and the full bobbin.

[0070] The working process of the above docking and transfer mechanism is as follows: When it is necessary to transfer the full bale cylinder conveyed by the second empty / full cylinder rotary conveying mechanism 5-2 to the main roadway conveying mechanism 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 a distance of one full bale cylinder towards the second empty / full cylinder rotary conveying mechanism 5-2. Then, the docking and transfer rotary push rod 807 rotates to the horizontal state. At this time, the full bale cylinder is located between the two docking and transfer rotary push rods 807. Next, the docking and transfer push-pull assembly drives the docking and transfer rotary push rod assembly to move a distance of one bale cylinder towards the main roadway conveying mechanism, that is, to push and pull the full bale cylinder on the lifting mechanism onto the main roadway conveying mechanism. Then, the docking and transfer rotary push rod 807 resets vertically upward, and the docking and transfer push-pull assembly drives the docking and transfer rotary push rod assembly to return to the original position. When it is necessary to transfer the empty bale cylinder on the main roadway conveying mechanism to the second empty / full cylinder rotary channel on one side of the second empty / full cylinder rotary conveying mechanism 5-2, 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 a distance of one empty bale cylinder towards the lifting plate. Then, the docking and transfer rotary push rod 807 rotates to the horizontal state. At this time, the empty bale cylinder above the main roadway conveying mechanism is located between the two horizontal docking and transfer rotary push rods 807. Next, the docking and transfer push-pull assembly drives the docking and transfer rotary push rod assembly to move towards the lifting plate. At this time, the docking and transfer rotary push rod 807 pushes the empty bale cylinder on the main roadway conveying mechanism onto the lifting plate. Then, the docking and transfer rotary push rod rotates vertically upward and the docking and transfer push-pull assembly drives the docking and transfer rotary push rod assembly to retreat a distance of one empty bale cylinder. At the same time, the lifting plate descends to be docked with the inclined plate. Then, the docking and transfer rotary push rod 807 rotates to the horizontal state again. The docking and transfer push-pull assembly drives the docking and transfer rotary push rod assembly to move forward and push the empty bale cylinder from the lifting plate onto the second empty / full cylinder rotary channel. Then, the docking and transfer rotary push rod 807 resets vertically upward, and the docking and transfer push-pull assembly drives the docking and transfer rotary push rod assembly to return to the original position.

[0071] Referring to Figure 13 , the above empty bale cylinder pushing mechanism 9 includes an empty bale cylinder pushing fixed frame 901, an empty bale cylinder pushing plate 902 and an empty bale cylinder pushing plate driving member. The empty bale cylinder pushing plate driving member specifically adopts an empty bale cylinder pushing driving cylinder 903. The cylinder body of the empty bale cylinder pushing driving cylinder 903 is fixed on the empty bale cylinder pushing fixed frame 901. One end of the piston rod of the empty bale cylinder pushing driving cylinder 903 is connected to the empty bale cylinder pushing plate 902. The empty bale cylinder pushing driving cylinder 903 drives the empty bale cylinder pushing plate 902 to push the empty bale cylinder.

[0072] In addition, to achieve the automated operation of the above drawframe and roving combined conveying device, the device further includes a control cabinet, and a PLC control system communicatively connected to the above-mentioned various mechanisms is arranged in the control cabinet. By setting corresponding control programs in the PLC control system, the various mechanisms automatically cooperate to execute corresponding action instructions.

[0073] In addition, for the sake of easy understanding, the process of changing empty and full cans of the above drawframe and roving combined conveying device is described.

[0074] The process of the empty can being conveyed by the sub-aisle conveying mechanism to the drawframe is as follows:

[0075] (a) The sub-aisle conveying mechanism conveys the empty can to the main-aisle conveying mechanism;

[0076] (b) The main-aisle conveying mechanism conveys the empty can to one end of the main-aisle conveying mechanism close to the lifting mechanism;

[0077] (c) The lifting mechanism raises the lifting plate to be flush with the aisle conveying plate of the main-aisle conveying mechanism, and the docking transfer mechanism pushes the empty can from the aisle conveying plate of the main-aisle conveying mechanism onto the lifting plate;

[0078] (d) The lifting mechanism lowers the lifting plate to be docked with the inclined plate, and the docking transfer mechanism pushes the empty can from the lifting plate onto the second empty / full can rotary channel;

[0079] (e) The second empty / full can rotary conveying mechanism pushes the empty can along the second empty / full can rotary channel to the docking point (i.e., the intersection) of the first and second empty / full can rotary channels; At this time, if it is necessary to store the empty can in the proximal empty can temporary storage channel, the proximal empty can temporary storage conveying mechanism is used to push and pull the empty can from the docking point of the first and second empty / full can rotary channels to the empty can temporary storage channel; If it is necessary to store the empty can in the distal empty can temporary storage channel, the empty can pushing mechanism first pushes the empty can to the first empty / full can rotary channel, and then the first empty / full can rotary conveying mechanism pushes the empty can along the first empty / full can rotary channel to the docking point of the first empty / full can rotary channel and the distal empty can temporary storage channel, and then the distal empty can temporary storage conveying mechanism pushes and pulls the empty can from this docking point to the empty can temporary storage channel;

[0080] (f) The empty can feeding conveying mechanism pushes the empty can at the outermost end of the empty can temporary storage channel (i.e., the empty can at the docking point of the empty can temporary storage channel and the empty can feeding channel) into the empty can feeding channel, and pushes the empty can along the empty can feeding channel to the drawframe inlet to complete the conveyance of the empty can.

[0081] The process of the full can spun by the drawframe being conveyed to the sub-aisle conveying mechanism is as follows:

[0082] (a) The drawing frame conveys the full creel from its outlet to the first empty / full creel rotary channel;

[0083] (b) The first empty / full creel rotary conveying mechanism pushes the full creel along the first empty / full creel rotary channel to the docking position of the first and second empty / full creel rotary channels;

[0084] (c) The proximal empty creel temporary storage and conveying mechanism pushes the full creel from the docking position of the first and second empty / full creel rotary channels to the second empty / full creel rotary channel. Then, the second empty / full creel rotary conveying mechanism pushes the full creel along the second empty / full creel rotary channel to one end near the lifting mechanism and pushes the full creel onto the lifting plate of the lifting mechanism through the inclined plate;

[0085] (d) The lifting mechanism drives the lifting plate to rise to be flush with the roadway conveying plate of the main roadway conveying mechanism. The docking and transfer mechanism pushes the full creel from the lifting plate onto the roadway conveying plate of the main roadway conveying mechanism. Then, the lifting plate descends and resets and docks with the inclined plate;

[0086] (e) The full creel pushing cylinder conveying component of the full creel pushing mechanism first drives the full creel pushing cylinder component to slide to the position of the sub-roadway conveying mechanism that requires a full creel for positioning. Then, the roadway conveying push plate of the main roadway conveying mechanism moves and stops conveying when the full creel reaches the sub-roadway conveying mechanism that requires a full creel. Then, the full creel pushing cylinder component pushes the full creel from the roadway conveying plate of the main roadway conveying mechanism to the roadway conveying plate of the sub-roadway conveying mechanism, completing the conveyance of the full creel.

[0087] In addition, by using the above drawing frame and roving combined conveying device, the empty creels and full creels of the roving frame can also be replaced without stopping the machine to change the creels. In this embodiment, a total of 7 conveying lines are provided for the sub-roadway conveying mechanism of the roving frame, and these 7 conveying lines are marked as the first to seventh sub-roadways from top to bottom. The specific creel-changing process is as follows:

[0088] (1) During the creel laying stage, first lay 5 / 5 full creels, 4 / 5 full creels, 3 / 5 full creels, 2 / 5 full creels, and 1 / 5 full creels in the first to fifth sub-roadways respectively. The sixth sub-roadway is idle, and 5 / 5 full creels are laid in the seventh sub-roadway; and the first to fifth sub-roadways are used as the in-spinning roadways, and the seventh sub-roadway is used as the standby roadway;

[0089] (2) The roving frame starts spinning. When 1 / 5 of the sliver in the creel has been consumed, the sliver in the creel of the fifth sub-lane is completely consumed and becomes an empty creel. At this time, there is no need to stop the machine. Workers can directly stand on the lane conveyor plate of the conveyor mechanism in the sixth sub-lane to splice the sliver in the spare full creel in the seventh sub-lane and use it as the spinning lane. At the same time, the empty creels of the fifth sub-lane are sequentially conveyed to the drawing frame, and then the drawing frame spins the empty creels into full creels and conveys the full creels to the sixth sub-lane as the spare lane, leaving the fifth sub-lane idle. It should be noted that during this process, the storage capacity of the empty creel temporary storage channels on both sides of the drawing frame is usually less than the number of empty creels on the fifth sub-lane. Therefore, some empty creels can be conveyed and temporarily stored in the empty creel temporary storage channels first, and then the drawing frame spins the conveyed partial empty creels full one by one and conveys them to the sixth sub-lane in sequence. Repeat this process until all the empty creels in the fifth sub-lane are spun into full creels and conveyed to the sixth sub-lane;

[0090] (4) When 1 / 5 of the sliver in the creel is consumed again, the sliver in the creel of the fourth sub-lane is completely consumed and becomes an empty creel. At this time, there is no need to stop the machine. Workers can directly stand on the lane conveyor plate of the conveyor mechanism in the fifth sub-lane to splice the sliver in the spare full creel in the sixth sub-lane and use it as the spinning lane. At the same time, the empty creels of the fourth sub-lane are sequentially conveyed to the drawing frame, and then the drawing frame spins the empty creels into full creels and conveys the full creels to the fifth sub-lane as the spare lane, leaving the fourth sub-lane idle;

[0091] (5) When 1 / 5 of the sliver in the creel is consumed again, the sliver in the creel of the third sub-lane is completely consumed and becomes an empty creel. At this time, there is no need to stop the machine. Workers can directly stand on the lane conveyor plate of the conveyor mechanism in the fourth sub-lane to splice the sliver in the spare full creel in the fifth sub-lane and use it as the spinning lane. At the same time, the empty creels of the third sub-lane are sequentially conveyed to the drawing frame, and then the drawing frame spins the empty creels into full creels and conveys the full creels to the fourth sub-lane as the spare lane, leaving the third sub-lane idle;

[0092] (6) When 1 / 5 of the sliver in the creel is consumed again, the sliver in the creel of the second sub-lane is completely consumed and becomes an empty creel. At this time, there is no need to stop the machine. Workers can directly stand on the lane conveyor plate of the conveyor mechanism in the third sub-lane to splice the sliver in the spare full creel in the fourth sub-lane and use it as the spinning lane. At the same time, the empty creels of the second sub-lane are sequentially conveyed to the drawing frame, and then the drawing frame spins the empty creels into full creels and conveys the full creels to the third sub-lane as the spare lane, leaving the second sub-lane idle;

[0093] (7) When 1 / 5 of the sliver in the can has been consumed again, the sliver in the can in the first sub-aisle is completely consumed and becomes an empty can. At this time, there is no need to stop the machine. Workers can directly stand on the aisle conveyor plate of the conveyor mechanism in the second sub-aisle to splice the sliver in the spare full can in the third sub-aisle and use it as the spinning aisle. At the same time, the empty cans in the first sub-aisle are sequentially conveyed to the drawing frame, and then the drawing frame spins the empty cans into full cans and conveys the full cans to the second sub-aisle as the spare aisle, leaving the first sub-aisle idle.

[0094] This process repeats in a cycle to complete the replacement of empty cans and full cans in the roving frame. During this process, there is no need to stop the machine for can replacement. It only requires pausing the winding mechanism of the roving frame in the corresponding sub-aisle when splicing after can replacement.

[0095] It should be noted that the parts not described in this invention can be implemented by adopting or referring to existing technologies.

[0096] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions, or substitutions made by those skilled in the art within the scope of the essence of the present invention should also fall within the protection scope of the present invention.
