Description

Technical Field

[0001] This invention belongs to the field of aluminum processing, and in particular relates to a sleeve transport circulation system used in aluminum processing equipment. Background Technology

[0002] In the aluminum processing industry, aluminum coils are typically wound onto sleeves, forming a complete coil unit. During the rolling process, the sleeve containing the original aluminum coil (master coil) is first loaded into the uncoiler, while an empty sleeve is pre-placed on the coiler. The uncoiler unwinds the aluminum strip and feeds it into the rolling equipment. The rolled aluminum strip is then rewound by the coiler onto its empty sleeve to form the finished coil. When the rolling cycle is completed (i.e., the aluminum coil on the uncoiler is exhausted), the sleeve on the uncoiler becomes an empty sleeve. At this point, the empty sleeve needs to be removed from the uncoiler station, and preparations need to be made to send the next empty sleeve of the required specifications to the coiling station to ensure continuous production. Therefore, the efficient and reliable transfer and supply of sleeves between the uncoiler and coiling sides is a core element in achieving continuous and automated operation of the aluminum rolling production line.

[0003] In actual production, to meet the production needs of aluminum coils with different widths and diameters, production lines often need to be equipped with sleeves of various specifications. However, the common method of sleeve transfer mainly relies on a fixed conveyor track between the uncoiler and the coiler. This method can usually only convey sleeves of a single specification in one direction along a preset path. It cannot, according to the actual needs of the production line, queue up and feed empty sleeves of the required specifications into the coiler. This limitation severely restricts the flexibility and efficiency of the production line, especially in multi-variety, small-batch rolling tasks. Summary of the Invention

[0011] Optionally, it also includes a second sleeve transfer device, which is disposed above the first end of the running track of the second transport trolley and is used to transfer the empty sleeve on the sleeve guide device to the second transport trolley.

[0012] Optionally, the second sleeve transfer device includes a second telescopic drive, two clamping arms, and two clamping assemblies; the two clamping arms are spaced apart, and each clamping arm is hinged to the ground of the first floor; each clamping arm is provided with a clamping assembly at the end away from the first floor, and the two clamping assemblies are used to clamp empty sleeves; the second telescopic drive is used to drive the two clamping arms to rotate, so as to transfer the empty sleeves clamped by the two clamping assemblies to the second transport trolley.

[0029] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification.

[0030] Please refer to all the accompanying drawings below. It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of the invention. Therefore, they have no substantial technical significance.

Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and are not intended to limit the scope of the invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention.

[0031] The following embodiments are for illustrative purposes only. These embodiments can be combined and are not limited to the content shown in any single embodiment below.

[0032] Please see Figure 1-7 This invention provides a sleeve transport circulation system for use on aluminum processing equipment, comprising: an uncoiler 1, a rolling mill 2, a coiler 3, and a sleeve guide device 4 located on a first floor 100; and a transport track 5, a first transport trolley 6, and a second transport trolley 7 located on a second floor 200. The rolling mill 2 is located between the uncoiler 1 and the coiler 3, and is used to roll the aluminum coil on the uncoiler 1. After rolling, the coil is fed into the coiler 3 and wound around the empty sleeve on the coiler 3.

[0033] The first end of the running track of the first transport trolley 6 is located below the uncoiler 1, and the second end corresponds to the entrance of the transport track 5. It is used to feed empty sleeves from the uncoiler 1 onto the transport track 5. The first end of the running track of the second transport trolley 7 corresponds to the exit of the transport track 5, and the second end is located below the coiler 3. The outlet of the sleeve inlet device 4 is located above the first end of the running track of the second transport trolley 7. It is used to provide empty sleeves of other specifications different from those output from the exit of the transport track 5, thereby achieving flexible supply of multiple specifications of sleeves and meeting the production needs of the coiler 3 for aluminum coils of different widths or diameters. The second transport trolley 7 is used to feed empty sleeves from the transport track 5 and empty sleeves conveyed by the sleeve inlet device 4 onto the coiler 3.

[0034] The first floor 100 and the second floor 200 are arranged in an adjacent upper and lower structure, with the first floor 100 located above the second floor 200. The transport track 5 and the sleeve guide device 4 can each adopt a belt conveyor mechanism to achieve efficient and stable transmission of empty sleeves.

[0035] Through its layered layout and multi-path conveying design, the system enables orderly and automated cyclic transport of sleeves between the unwinding and winding sides. It also supports flexible switching and supply of sleeves of various specifications, thereby improving the automation level and operational flexibility of the production line.

[0036] The sleeve transport and circulation system also includes a residual coil processing device 8 installed on the first floor 100. This device 8 is located above the second end of the running track of the first transport trolley 6 and is used to strip and clean the sleeves unloaded from the uncoiler 1 that still contain residual aluminum coils, restoring them to an empty sleeve state. During the process of transporting the sleeve with residual coils from below the uncoiler 1 to the corresponding position at the entrance of the transport track 5, the first transport trolley 6 can lift the sleeve and send it into the residual coil processing device 8 for processing. After the residual coil processing is completed, the resulting empty sleeve is then transferred by the first transport trolley 6 to the entrance of the transport track 5 for subsequent conveying and circulation. This design integrates the residual coil processing flow with the sleeve transport and circulation system, avoiding the need for manual hoisting or offline processing of residual coils, further improving the system's automation and operational continuity.

[0037] The sleeve transport circulation system also includes a first sleeve transfer device 9, which is located at the second end of the running track of the first transport trolley 6 and is used to transfer empty sleeves on the first transport trolley 6 to the transport track 5.

[0038] The first transport trolley 6 includes a base 61, a traveling mechanism 64, a scissor lift mechanism, a fixed base 63, and a fixed plate 65. The traveling mechanism 64 is mounted on the base 61 and includes a battery, a drive motor, and multiple wheels mounted on the base 61. The wheels are spaced apart on the base 61. The drive motor is electrically connected to the battery and drives the wheels to move, thereby moving the base 61 on the second floor 200.

[0039] The fixed end of the scissor lift mechanism is mounted on the base 61, and its movable output end is connected to the fixed seat 63, which can drive the fixed seat 63 to lift vertically. The upper surface of the fixed plate 65 is provided with a V-shaped limiting part 651 for stabilizing and supporting the empty sleeve. Its lower surface includes a parallel part 652 and an inclined part 653, wherein the inclined part 653 is hinged to the fixed seat 63 through a pivot, and the parallel part 652 is used to abut against the upper surface of the fixed seat 63.

[0040] When the first transport trolley 6 moves to the first end along the running track, the scissor lift mechanism drives the fixed seat 63 to move upward. The empty sleeve on the uncoiler 1 can be transferred to the fixed plate 65 through the clamping structure and limited by the V-shaped limiting part 651. Subsequently, the scissor lift mechanism drives the fixed seat 63 to return to its original position downward, and the traveling mechanism 64 drives the base 61 to the entrance of the transport track 5. The first sleeve transfer device 9 then places the empty sleeve onto the transport track 5. When there are residual rolls on the empty sleeves of the first transport trolley 6, the scissor lift mechanism drives the fixed seat 63 to move upward. The empty sleeves on the fixed seat 63 can be transferred to the residual roll processing device 8 for processing by the clamping mechanism on the residual roll processing device 8. After processing, they are placed back onto the first transport trolley 6. Afterward, the scissor lift mechanism drives the fixed seat 63 to move downward again, and the first sleeve transfer device 9 places the empty sleeve onto the transport track 5.

[0041] The first sleeve transfer device 9 includes a mounting base 91 and a first telescopic drive member 92. The mounting base 91 is set on the ground of the second floor 200. The first telescopic drive member 92 can be a cylinder, with its fixed end set on the mounting base 91 and its output end used to abut against the end of the parallel part 652 away from the inclined part 653.

[0042] When the first transport trolley 6 transports the sleeve to the entrance of the transport track 5, the output end of the first telescopic drive member 92 extends and pushes upward the end of the parallel portion 652 on the lower surface of the fixed plate 65 away from the inclined hinge axis. This pushing force causes the fixed plate 65 to rotate upward around the hinge axis of the inclined portion 653, and the empty sleeve, which was originally fixed by the V-shaped limiting portion 651, slides down along the surface of the inclined fixed plate 65 and falls smoothly onto the transport track 5 below, completing the transfer from the transport trolley to the fixed track.

[0043] The first transport trolley 6 and the second transport trolley 7 can have the same structure.

[0044] The sleeve transport circulation system also includes a second sleeve transfer device 10, which is positioned above the first end of the running trajectory of the second transport trolley 7. This device transfers empty sleeves from the sleeve guide device 4 onto the second transport trolley 7. Specifically, the second sleeve transfer device 10 includes a second telescopic drive member 101, two clamping arms 102, a connecting arm 103, and two clamping assemblies 104. The two clamping arms 102 are spaced apart, and each clamping arm 102 is hinged to the ground of the first floor 100. The two ends of the connecting arm 103 are connected to one clamping arm 102 respectively. Each clamping arm 102 has a clamping assembly 104 at its end furthest from the first floor 100. The two clamping assemblies 104 are used to clamp empty sleeves. The second telescopic drive member 101 can be a cylinder, connected to the connecting arm 103, used to drive the two clamping arms 102 to rotate, thereby transferring the empty sleeves clamped by the two clamping assemblies 104 onto the second transport trolley 7.

[0045] The clamping assembly 104 may include a third telescopic drive member 1041, an abutment member 1042, and a limiting post 1043. The third telescopic drive member 1041 may be a cylinder, with its fixed end located at the end of the clamping arm 102 away from the first floor 100. The abutment member 1042 and the limiting post 1043 are located at the output end of the third telescopic drive member 1041. The abutment member 1042 may be an abutment plate, with an elastic element made of rubber or other materials provided on the end of the abutment plate facing the empty sleeve. The abutment member 1042 is used to abut against the end of the empty sleeve, and the limiting post 1043 is used to abut against the inner wall of the empty sleeve.

[0046] In use, when the second telescopic drive 101 drives the two clamping arms 102 to be above the outlet of the sleeve inlet device 4, the two third telescopic drive members 1041 drive the corresponding abutment members 1042 and limiting members to move, thereby clamping the empty sleeve. Then, the second telescopic drive 101 drives the two clamping arms 102 to rotate, thereby transferring the empty sleeve to the fixed plate 65 of the second transport trolley 7. Subsequently, the third telescopic drive members 1041 release the clamping of the empty sleeve. Finally, the second transport trolley 7 feeds the empty sleeve into the winding machine 3.

[0047] A blocking component 51 may also be provided on the transport track 5. The blocking component 51 is used to controllably block the empty sleeves on the transport track 5 during the transport process, so as to realize the orderly buffering and on-demand release of the empty sleeves, thereby coordinating the production rhythm of the preceding and following processes.

[0048] The blocking assembly 51 includes a shift fork 511 and a fourth telescopic drive member 512. The shift fork 511 is hinged to the bottom structure of the transport track 5 via a hinge shaft, allowing it to swing within a certain angle range around the hinge shaft. The fourth telescopic drive member 512 can be a cylinder, with its fixed end mounted on a frame to the side or below the transport track 5, and its output end connected to the rod of the shift fork 511 via a hinge. When the fourth telescopic drive member 512 extends, its output end pushes the shift fork 511 to rotate upwards around the bottom hinge shaft, raising the working end of the shift fork 511 and extending it above the conveying space of the transport track 5, thus mechanically blocking the moving empty sleeve. When the fourth telescopic drive member 512 retracts, the shift fork 511 rotates downwards below the track plane under gravity, releasing the blocking state and allowing the empty sleeve to continue forward transport.

[0049] The setting of the blocking component 51 enables the transport track 5 to have segmented control and temporary storage functions, which can flexibly adapt to the conveying rhythm of different specifications of sleeves, and facilitate the accurate placement of individual sleeves, thereby improving the automation level and operational reliability of the entire transport system.

[0050] The transport track 5 also includes multiple limiting components for accommodating sleeves of different sizes. Each limiting component includes two parallel and spaced guide bars 521, which extend along the transport direction of the track and are respectively located on both sides of the transport track 5. When an empty sleeve is transported on the track, its two ends can abut against the inner surface of the corresponding guide bar 521, thereby achieving lateral limiting and guiding of the empty sleeve during transport.

[0051] The spacing between the two guide bars 521 of each limiting component is set to match an empty sleeve of a specific length (i.e., the axial dimension of the sleeve). In other words, the spacing between the guide bars 521 of different limiting components is different, ensuring that each limiting component can effectively limit and guide only an empty sleeve of a specific length corresponding to its spacing. This design allows the same transport track 5 to stably transport various lengths of empty sleeves, achieving orderly and precise transmission of multiple sleeve specifications without manual adjustment of the track structure, further enhancing the system's versatility and automation level.

[0052] In summary, this invention effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0053] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
