Description

Technical Field

[0001] The invention belongs to the field of workshop coil transportation, and in particular relates to a coil logistics transportation system and a use method thereof. Background Art

[0002] On the rolling mill coil production line, the coiled coil needs to be transported from the raw material warehouse to the rolling mill production line. The rolling mill production line is usually equipped with auxiliary equipment such as preparation stations and inspection stations, which requires the coils to be frequently transported to the preparation station, inspection station, rolling mill unwinder and rolling mill coiler for loading and unloading operations. The traditional method is to use a crane for lifting. The labor intensity of the crane operator is relatively high, and it requires multiple people to cooperate in lifting. There are also disadvantages such as not being able to cross and lifting dead zones. Frequent lifting is also easy to scratch the coils, the production rhythm is not good, and the efficiency is relatively low. Later, on some continuous rolling production lines, chain conveyors and walking beams for transporting coils appeared. Chain conveyors and walking beams effectively solved the problems of the crane, but the mechanical structure is relatively complex, requiring a relatively large amount of civil construction, and are not suitable for installation and maintenance. The transportation rhythm of chain conveyors and walking beams is also slow, the efficiency is not high, and they are not suitable for production lines that require frequent transportation. Summary of the invention

Roller transport platform; the inspection station transport track intersects with the third row of rollers at roller transport platform No. 18 and with the second row of rollers at roller transport platform No. 19, and the preparation station, rolling mill entrance uncoiler, rolling mill exit coiler and inspection station are distributed from left to right; roller transport platform No. 1, roller transport platform No. 36, roller transport platform No. 8, roller transport platform No. 11, roller transport platform No. 26 and roller transport platform No. 18 are all equipped with passages for transport vehicles to pass through.

[0005] A horizontal and height centering device is connected to the transport track between the preparation station and the third row of rollers; a horizontal and height centering device is connected to the transport track between the rolling mill entrance uncoiler and the third row of rollers; a horizontal and height centering device is connected to the transport track between the inspection station and the third row of rollers.

[0006] The first row of rollers consists of roller transport platform No. 1 to roller transport platform No. 18 from left to right; the second row of rollers consists of roller transport platform No. 19 to roller transport platform No. 36 from right to left; the third row of rollers consists of roller transport platform No. 37 to roller transport platform No. 46 from left to right.

[0007] A roller transport platform between the No. 1 roller transport platform and the No. 8 roller transport platform is a rotating roller platform, and a roller transport platform between the No. 26 roller transport platform and the No. 29 roller transport platform is a rotating roller platform.

[0008] The No. 41 roller conveying platform in the third row of rollers is connected to the discharge port of the raw material warehouse through a track, and a coil-taking trolley is placed on the track.

[0009] Rubber buffer pads are placed at the bottom of the No. 38 roller transport platform, the No. 39 roller transport platform and the No. 40 roller transport platform in the third row of rollers.

[0010] A method for using a coil logistics transportation system comprises the following steps:

[0011] Step 1: Coil taking and coil preparation: take the pallet with coils from the raw material warehouse and place it on the coil taking trolley. The coil taking trolley moves along the track and places the coils to be rolled and the pallet on the No. 41 roller conveyor platform. Then, the pallet with coils is transported to the No. 37 roller conveyor platform.

[0012] The second step is to load and unload the coils at the preparation station. The transport trolley of the preparation station moves along the transport track of the preparation station to the No. 37 roller transport platform, takes away the pallet with the coils, and then transports the pallet with the coils to the horizontal and height centering device of the preparation station to automatically align the coils horizontally and highly. Then the transport trolley of the preparation station transports the coils to the reel center of the uncoiler of the preparation station to perform the preparation station operation. After completion, the transport trolley of the preparation station unloads the coils from the uncoiler and transports the coils to the No. 1 roller transport platform;

[0013] Step 3: For the first rolling, the strip coil is transported from the No. 1 roller conveyor platform to the No. 8 roller conveyor platform. During the rolling process, the strip coil passes through the rotating roller conveyor platform and rotates 180° to complete the turning of the strip head. The transport trolley of the uncoiler at the mill entrance takes the strip coil off the No. 8 roller conveyor platform and transports it to the horizontal and height centering device of the uncoiler at the mill entrance to automatically center the strip coil horizontally and highly. Then, the strip coil is sent to the center of the reel of the uncoiler at the mill entrance for rolling. The rolled strip coil comes out of the mill exit coiler and is placed on the transport trolley of the mill exit coiler.

[0014] The fourth step is to put the finished products into storage. The transport trolley of the rolling mill exit coiler transports the coil to the No. 46 roller transport platform, and then transfers it to the No. 41 roller transport platform. The coiling trolley then transports the rolled coil on the No. 41 roller transport platform to the finished product warehouse in the raw material warehouse.

[0015] In the third step, if secondary rolling is performed, the strip is transported to the No. 26 roller transport platform, and then transported to the No. 29 roller transport platform through the roller transport platform. During this period, the strip coil is turned by rotating the roller platform. The transport trolley of the uncoiler at the rolling mill entrance takes the strip coil off the No. 29 roller transport platform, and is transported to the horizontal and height centering device of the uncoiler at the rolling mill entrance again to automatically align the horizontal and height of the strip coil, and then it is sent to the center of the reel of the uncoiler at the rolling mill entrance for rolling.

[0016] After the third step, the inspection station also prepares and coils the strip coils. The transport trolley of the rolling mill exit coiler transports the strip coils to the No. 11 roller transport platform, and then transports it to the No. 18 roller transport platform via the roller transport platform. The transport trolley of the inspection station takes the strip coils from the No. 18 roller transport platform and transports it to the center of the reel of the unwinder at the inspection station, and then performs an inspection operation. During the transportation, the horizontal and height centering device of the inspection station automatically performs the horizontal and height centering of the strip coils. After the inspection is completed, the transport trolley of the inspection station takes the strip coils from the coiler of the inspection station and transports it to the No. 19 roller transport platform, and then transports it to the No. 26 roller transport platform from the roller transport platform, and then enters the fourth step.

[0017] The beneficial effects of the present invention are as follows: through roller tables, various standby stations, rolling mill entrance uncoilers, rolling mill exit coilers and inspection stations are connected together, and the raw material warehouse and the rolling mill span are connected, and then four transport carts are used to realize full-automatic transportation of the coils. It has the characteristics of easy installation, use and maintenance, full-automatic operation, fast coil transportation rhythm, and little damage to the coils. BRIEF DESCRIPTION OF THE DRAWINGS

The preparation station 109, the mill entrance uncoiler 110, the mill exit coiler 111 and the inspection station 112 all extend the transport track in the direction of the raw material warehouse. The transport tracks of the preparation station 109, the mill entrance uncoiler 110, the mill exit coiler 111 and the inspection station 112 are parallel to each other and perpendicular to the third row of rollers 103. Transport trolleys 104 are placed on the transport tracks of the preparation station 109, the mill entrance uncoiler 110, the mill exit coiler 111 and the inspection station 112. The transport track of the preparation station 109 intersects with the third row of rollers 103 at the No. 1 roller transport track. Platform 1, intersecting with the second row of rollers 102 at the thirty-sixth roller transport platform 36, and intersecting with the first row of rollers 101 at the thirty-seventh roller transport platform 37; the transport track of the unwinder 110 at the rolling mill entrance intersects with the third row of rollers 103 at the eighth roller transport platform 8, and intersects with the second row of rollers 102 at the twenty-ninth roller transport platform 29; the transport track of the coiler 111 at the rolling mill exit intersects with the third row of rollers 103 at the eleventh roller transport platform 11, intersects with the second row of rollers 102 at the twenty-sixth roller transport platform 26, and intersects with the first row of rollers 101 at the forty-sixth roller transport platform The transport track of the inspection station 112 intersects with the third row of rollers 103 at the eighteenth roller transport platform 18 and intersects with the second row of rollers 102 at the nineteenth roller transport platform 19, and the preparation station 109, the rolling mill entrance unwinder 110, the rolling mill exit coiler 111 and the inspection station 112 are distributed from left to right; the first roller transport platform 1, the thirty-sixth roller transport platform 36, the eighth roller transport platform 8, the eleventh roller transport platform 11, the twenty-sixth roller transport platform 26 and the eighteenth roller transport platform 18 are all provided with passages for the transport trolley 104 to pass through.

[0026] From bottom to top, there are three horizontal roller tables: the first row 101, the second row 102 and the third row 103. The second row 102 and the third row 103 are located on one side of the rolling mill span, and the first row 101 is located on one side of the raw material span.

[0027] From left to right, the preparation station 109, the rolling mill entrance uncoiler 110, the rolling mill exit coiler 111 and the inspection station 112 all have downwardly extending transport tracks for the transport trolley 104 to move on the transport tracks. Figures 2 to 4As shown, the transport track extending from the preparation station 109 passes through the second row of rollers 102 and the third row of rollers 103 from underground, and the No. 1 roller transport platform 1 and the No. 36 roller transport platform 36 at the passing position are provided with passages, which allow the transport track to pass through the roller transport platform, so that the transport trolley 104 can pass through the second row of rollers 102 and reach the position of the first row of rollers 101 from the third row of rollers 103. The same is true for the intersections of other transport tracks with the first row of rollers 101, the second row of rollers 102 and the third row of rollers 103. And each transport track is in a vertical state and intersects with the third row of rollers 103 at right angles.

[0028] The rolling mill is located between the uncoiler 110 at the rolling mill entrance and the coiler 111 at the rolling mill exit. The strip coil enters the rolling mill from the uncoiler 110 at the rolling mill entrance and then exits from the coiler 111 at the rolling mill exit.

[0029] [Example 2]

[0030] like Figures 1 to 4 As shown, on the basis of Example 1, a horizontal and height centering device 105 is connected to the transport track between the preparation station 109 and the third row of rollers 103; a horizontal and height centering device 105 is connected to the transport track between the rolling mill entrance uncoiler 110 and the third row of rollers 103; and a horizontal and height centering device 105 is connected to the transport track between the inspection station 112 and the third row of rollers 103.

[0031] The transport tracks of the preparation station 109, the mill entrance uncoiler 110, and the inspection station 112 are all connected with the horizontal and height centering device 105, which is used to horizontally and height-center the coils transported by the transport trolley 104 before coiling. In conjunction with the travel encoder on the transport trolley 104, fully automatic coiling can be achieved.

[0032] The first row of rollers 101 consists of roller transport platform No. 1 to roller transport platform No. 18 from left to right; the second row of rollers 102 consists of roller transport platform No. 19 to roller transport platform No. 36 from right to left; the third row of rollers 103 consists of roller transport platform No. 37 to roller transport platform No. 46 from left to right.

[0033] The first row of rollers 101 is composed of 18 roller transport platforms, but in actual use it is not limited to 18, and the transport capacity of the roller transport platforms can be increased or decreased according to the actual site conditions. The second row of rollers 102 and the third row of rollers 103 are similar.

[0034] A roller transport platform between the roller transport platform No. 1 to the roller transport platform No. 8 8 is a rotating roller transport platform, and a roller transport platform between the roller transport platform No. 26 26 and the roller transport platform No. 29 29 is a rotating roller transport platform.

[0035] A roller conveyor platform between the first roller conveyor platform 1 and the eighth roller conveyor platform 8 is a rotating roller conveyor platform. Figure 1 and Figure 2 As shown, the third roller conveyor platform 3 is a rotating roller conveyor platform, which can drive the pallet-level coils thereon to turn. In actual use, the third roller conveyor platform 3 may not be selected, and it can be between the first roller conveyor platform 1 and the eighth roller conveyor platform 8. The same is true for the rotating roller platform between the twenty-sixth roller conveyor platform 26 and the twenty-ninth roller conveyor platform 29.

[0036] The No. 41 roller conveying platform 41 in the third row of rollers 103 is connected to the discharge port of the raw material warehouse through a track, and a coiling trolley 113 is placed on the track.

[0037] The third row of rollers 103 is located in the raw material span. Except for roller transport platform No. 37 and roller transport platform No. 46, any one of the third row of rollers 103 can be connected to the discharge port of the raw material warehouse through a track, and is not limited to roller transport platform No. 41.

[0038] Rubber buffer pads are placed at the bottom of the No. 38 roller conveyor platform 38, the No. 39 roller conveyor platform 39 and the No. 40 roller conveyor platform 40 in the third row of rollers 103.

[0039] The conveyor coil can also be automatically lifted by the unmanned overhead crane in the raw material warehouse to a roller transport platform with rubber buffer pads to reduce the impact on the roller transport platform when the overhead crane lifts the coil.

[0040] Each roller conveyor platform drives the sprocket wheel through the motor to realize the rotation of the conveyor roller, and the pallet is placed on the conveyor roller. As the conveyor roller rotates, the pallet can be driven to move forward and backward. The belt roll is placed on the pallet, so that the belt roll can be transported on each row of conveyor rollers. Between each row of rollers, the pallet is transported by the transport trolley 104 intersecting with the rollers. All roller conveyor platforms are equipped with proximity switches to realize the automatic start and stop of each roller conveyor platform.

[0041] [Example 3]

[0042] As Figures 1 to 4 As shown, based on Example 2, a method for using a coil logistics transportation system includes the following steps:

[0043] Step 1: coiling and coil preparation. Take the tray with the coil from the raw material warehouse and place the tray on the coiling trolley 113. The coiling trolley 113 moves along the track and places the coil to be rolled and the tray on the No. 41 roller conveyor platform 41. Then, the tray with the coil is transported to the No. 37 roller conveyor platform 37.

[0044] The strip coil to be processed together with the pallet underneath is taken out from the raw material warehouse and placed on the material picking trolley 113. The material picking trolley 113 goes up along the track to the 41st roller conveyor platform 41, puts the strip coil and the pallet on the 41st roller conveyor platform 41, and then sends them to the 37th roller conveyor platform 37 via the roller conveyor platform.

[0045] Step 2: Coil loading and unloading at the preparation station. The transport trolley 104 of the preparation station 109 moves along the transport track of the preparation station 109 to the No. 37 roller transport platform 37, takes away the pallet with the coil, and then transports the pallet with the coil to the horizontal and height centering device 105 of the preparation station 109 to automatically center the coil horizontally and highly. Then, the transport trolley 104 of the preparation station 109 transports the coil to the reel center of the uncoiler of the preparation station 109 to perform the preparation station operation. After completion, the transport trolley 104 of the preparation station 109 unloads the coil from the uncoiler and transports the coil to the No. 1 roller transport platform 1.

[0046] The transport cart 104 of the preparation station 109 moves to the thirty-seventh roller transport platform 37, takes away the strip coil, and then moves to the uncoiler of the preparation station 109. During the process, it is centered by the horizontal and height centering device 105 of the preparation station 109. After the centering is completed, the transport cart 104 transports it to the center of the uncoiler reel for preparation operation. After the operation, the strip coil is unloaded, placed on the transport cart 104 and transported to the first roller transport platform 1.

[0047] Step 3: For the first rolling, the strip coil is transported from the No. 1 roller conveyor platform 1 to the No. 8 roller conveyor platform 8. During the rolling process, the strip coil passes through the rotating roller conveyor platform and rotates 180° to complete the turning of the strip head. The transport trolley 104 of the mill entrance uncoiler 110 takes the strip coil off the No. 8 roller conveyor platform 8 and transports it to the horizontal and height centering device 105 of the mill entrance uncoiler 110 to automatically center the strip coil horizontally and highly. The strip coil is then sent to the center of the coil drum of the mill entrance uncoiler 110 for rolling. The rolled strip coil comes out of the mill exit coiler 111 and is placed on the transport trolley 104 of the mill exit coiler 111.

[0048] After the inspection at the preparation station, the strip coil is transported from the No. 1 roller transport platform 1 to the No. 8 roller transport platform 8. During this period, the strip coil is turned 180° by the rotating roller transport platform of the No. 3 roller transport platform 3, and the transport trolley 104 of the rolling mill entrance uncoiler 110 takes it down from the No. 8 roller transport platform 8 and transports it toward the rolling mill entrance uncoiler 110. During this period, the strip coil is also horizontally and highly aligned. After entering the rolling mill entrance uncoiler 110, the strip coil enters the rolling mill for processing, comes out from the rolling mill exit coiler 111, and is placed on the transport trolley 104 of the rolling mill exit coiler 111.

[0049] Step 4: Finished products are put into storage. The transport trolley 104 of the rolling mill exit coiler 111 transports the strip coil to the 46th roller transport platform 46, and then transfers it to the 41st roller transport platform 41. The coiling trolley 113 then transports the strip coil rolled on the 41st roller transport platform 41 to the finished product warehouse in the raw material warehouse.

[0050] The transport trolley 104 of the rolling mill exit coiler 111 transports the strip coil to the 46th roller transport platform 46, and then sends it to the 41st roller transport platform 41 via the roller transport platform. Finally, the coiling trolley 113 takes away the processed strip coil and sends it to the finished product warehouse in the raw material warehouse.

[0051] In the third step, if secondary rolling is performed, the strip is transported to the No. 26 roller transport platform 26, and then transported to the No. 29 roller transport platform 29 through the roller transport platform. During this period, the strip coil is turned by rotating the roller platform. The transport trolley 104 of the uncoiler 110 at the rolling mill entrance takes the strip coil off the No. 29 roller transport platform 29, and is transported to the rolling mill entrance uncoiler 110 again. The horizontal and height centering device 105 automatically aligns the horizontal and height of the strip coil, and then it is sent to the center of the reel of the uncoiler 110 at the rolling mill entrance for rolling.

[0052] In actual work, one rolling may not be enough and multiple rolling is required. In this case, the strip coil on the transport trolley 104 of the rolling mill exit coiler 111 is transported to the No. 26 roller transport platform 26, and then transported to the No. 29 roller transport platform 29 after turning. The transport trolley 104 of the rolling mill entrance decoiler 110 takes the strip coil on the No. 29 roller transport platform 29 and sends it to the rolling mill entrance decoiler 110 for secondary rolling.

[0053] After the third step, the inspection station also prepares and coils the strip coils. The transport trolley 104 of the rolling mill exit coiler 11 transports the strip coils to the No. 11 roller transport platform 11, and then transports them to the No. 18 roller transport platform 18 via the roller transport platform. The transport trolley 104 of the inspection station 112 takes the strip coils from the No. 18 roller transport platform 18, and transports them to the reel center of the unwinder at the inspection station 112, and then performs an inspection operation. During the transportation, the horizontal and height centering device 105 of the inspection station 112 automatically performs the horizontal and height centering of the strip coils. After the inspection is completed, the transport trolley 104 of the inspection station 112 takes the strip coils from the coiler at the inspection station 112, transports them to the No. 19 roller transport platform 19, and then transports them to the No. 26 roller transport platform 26 by the roller transport platform, and then enters the fourth step.

[0054] After rolling is completed, if inspection at the inspection station 112 is required, the transport trolley 104 of the rolling mill exit coiler 11 will transport the coil to the eleventh roller transport platform 11, and then transport it to the eighteenth roller transport platform 18.

[0055] The transport cart 104 at the inspection station 112 takes the strip coil and sends it to the inspection station 112 for inspection. During the inspection, the level and height of the strip coil are also aligned. After the inspection is completed, the transport cart 104 sends the strip coil to the 19th roller transport platform 19, and then transports it to the roller transport platform 26, and then enters the fourth step to put the finished strip coil into storage.

[0056] There are some abnormal situations in the rolling process, which can also be solved by this logistics system:

[0057] The strip at the entrance of the rolling mill is returned to the preparation station for re-preparation: the strip coil is unloaded from the rolling mill uncoiler 110 by the transport trolley 104 and transported to the No. 29 transport roller platform 29, and then transported to the No. 27 transport roller platform 27, for a 180° turn of the strip head, and then transported to the No. 36 roller transport platform 36, and rolled up to the preparation station 109 by the transport trolley 104 of the preparation station 109 for re-coiling preparation. After the preparation is completed, the strip coil is unloaded to the No. 1 transport roller to platform 1 by the transport trolley 104 of the preparation station 109, and the rolling mill is re-run for coiling preparation, and the rolling mill is re-coiled.

[0058] Strip breaking during rolling process: If the strip breaks during rolling process, the broken strip remnant needs to be unloaded from the rolling mill unwinder 110, and an empty pallet needs to be transported to the rolling mill unwinder 110 again. The empty pallet is transported from the raw material warehouse to the No. 41 roller conveyor platform 41 through the coiling trolley 13, and then transported to the No. 37 roller conveyor platform 37, and then transported to the No. 36 roller conveyor platform 36 through the transport trolley 104 of the preparation station 109, and then transported to the No. 29 roller conveyor platform 29, and then Then it is transported to the reel of the rolling mill uncoiler 110 through the transport trolley 104, and the broken strip remnant is unloaded and transported to the No. 29 roller transport platform 29, and then transported to the No. 26 roller transport platform 26 through the transport roller, and then transported to the No. 46 roller transport platform 46 through the transport trolley 104 of the rolling mill exit coiler 111, and then transported to the No. 41 roller transport platform 41 through the transport roller, and transported to the designated location by the coiler.
