Description

Technical Field

[0001] This application relates to the field of material logistics conveying equipment technology, and in particular to a horizontally moving material preparation vehicle, a material preparation method for the horizontally moving material preparation vehicle, and a control method for a material stack transfer system. Background Technology

[0002] Currently, various metal coils, such as aluminum coils and steel coils, need to undergo multiple processing steps before they can be sold as commodities. For example, aluminum alloy coils need to be rolled multiple times, and then slit and rolled into small coils of different specifications according to order requirements. Finally, the small aluminum foil coils are annealed according to process requirements before being packaged and stored.

[0003] After slitting, a finished aluminum foil master roll can be cut into several small aluminum foil rolls. To prevent damage during production and turnover that could lead to product scrap, the small aluminum foil rolls need to be placed in a special rack. Since most production enterprises do not have their slitting and processing workshops, annealing workshops, and packaging workshops in the same workshop, and the workshops are generally separated by a span, operators must use overhead cranes to hoist racks containing small rolls of aluminum foil from the slitting workshop to the cross-span flatcar during annealing operations. Then, the cross-span flatcar is used to transfer the racks to the annealing workshop. The overhead crane is then used to lift the racks from the cross-span flatcar and transfer them to the storage platform, where they are then pulled to the annealing furnace by a special material car for annealing. Since the cross-span flatcar is generally a flatbed trolley with a load capacity of about 5 tons, and the furnace capacity of an annealing furnace is about 30 tons, it takes 6 trips by the cross-span flatcar and 12 trips by the overhead crane to fill a furnace rack. For a medium-sized aluminum foil production enterprise with 40 annealing furnaces and a monthly production of 5,000 tons of aluminum foil, this means that the number of flatcar transfers is as high as 1,000 times per month, and the number of overhead crane hoistings is as high as 2,000 times per month.

[0004] In related technologies, a daughter car track is set on the material preparation mother car, and an additional movable bracket is slidably installed on the daughter car track, so that the material rack is fixedly installed on the movable bracket. By moving the movable bracket relative to the material preparation mother car, the number of transfer trips of the material preparation mother car is reduced. However, the current positioning between the movable bracket and the material preparation mother car generally requires manual operation by the operator, which not only increases the operator's workload and transfer risks, but also directly leads to a number of problems such as extended waiting time for materials in the annealing furnace, increased total annealing production time, low production efficiency, and increased production costs.

[0005] The above content is only used to help understand the technical solution of the invention and does not represent an admission that the above content is prior art. Summary of the Invention

[0006] In view of the above problems, the present invention proposes a horizontally moving material preparation vehicle, a material preparation method for the horizontally moving material preparation vehicle, and a control method for a material stack transfer system, aiming to solve at least one of the above-mentioned technical problems.

[0007] To achieve the above objectives, the horizontally moving material preparation vehicle proposed in this invention includes a material preparation mother car, a material preparation daughter car, and an electronic control system;

[0008] The material preparation mother car includes a mother car body, a daughter car track installed on the mother car body, a bracket limiting mechanism, and a bracket locking mechanism. The mother car body can move horizontally along the extension direction of the ground track. The mother car body includes a head and a tail located at both ends. The bracket limiting mechanism and the bracket locking mechanism are installed at the head of the mother car body. The bracket locking mechanism has a locked position and an unlocked position.

[0009] The material preparation trolley includes a movable bracket, which is horizontally connected to the trolley track and can move along the extension direction of the trolley track. The movable bracket is provided with a fastening mechanism. When the material preparation trolley moves along the trolley track to a preset stationary position, the bracket limiting mechanism limits and abuts against the movable bracket in the extension direction of the trolley track. In the locked position, the bracket locking mechanism cooperates with the fastening mechanism to restrict the movement of the movable bracket on the trolley track. In the unlocked position, the bracket locking mechanism disengages from the fastening mechanism, so that the movable bracket can move toward the rear of the mother car body.

[0010] The electrical control system includes a control module electrically connected to each other, and a trolley positioning detection element and a guide rail positioning detection element electrically connected to the control module. The trolley positioning detection element provides a trolley positioning signal when the movable bracket abuts against the bracket limiting mechanism, and the guide rail positioning detection element provides an unlocking signal when the transition guide rail of the connecting material trolley overlaps with the rear of the mother car body. The control module is electrically connected to the bracket locking mechanism to control the bracket locking mechanism to switch to the locking position after receiving the trolley positioning signal. The control module is also used to control the bracket locking mechanism to switch to the unlocking position when receiving the unlocking signal.

[0013] Upon receiving the transfer signal, the electronically controlled positioning mechanism is disengaged from the positioning base.

[0014] In one embodiment, the preparation mother car further includes traveling wheels and a drive mechanism. The traveling wheels are mounted on the bottom of the mother car body and are horizontally connected to the ground track along the extension direction of the ground track. The traveling wheels include driving wheels and driven wheels. The drive mechanism is used to drive the driving wheels to rotate and is electrically connected to the control module. The control module is also used to control the drive mechanism to drive the driving wheels to move the mother car body after receiving the transfer signal.

[0015] In one embodiment, the electronic control system further includes a guide rail positioning detection element and / or a communication module electrically connected to the control module. The guide rail positioning detection element is used to provide an unlocking signal when the transition guide rail of the connecting material vehicle overlaps with the rear of the mother vehicle body. The communication module is used to transmit a transfer signal to the control module after receiving a material preparation completion signal, and to send a loading and unloading signal to the connecting material vehicle when the electronic positioning mechanism is locked with the positioning base.

[0016] The present invention also proposes a material preparation method for a horizontally moving material preparation vehicle, applicable to the horizontally moving material preparation vehicle as described above, wherein the material preparation method for the horizontally moving material preparation vehicle includes the following steps:

[0017] Upon receiving the signal that the vehicle has arrived, control the bracket locking mechanism to start and switch the bracket locking mechanism to the locked position;

[0018] Upon receiving an unlock signal, the bracket locking mechanism is controlled to switch to the unlock position.

[0019] In one embodiment, after the step of receiving the vehicle arrival signal and controlling the bracket locking mechanism to start and switch the bracket locking mechanism to the locked position, and before the step of receiving the unlock signal and controlling the bracket locking mechanism to switch to the unlock position, the following steps are included:

[0020] Upon receiving a material preparation signal, the material preparation mother car is controlled to move the unloaded movable bracket to a preset starting position.

[0021] Upon receiving a material preparation completion signal, the material preparation trolley is controlled to move the movable bracket carrying the load to a preset endpoint position.

Upon receiving the mother car endpoint position arrival signal, the system controls the electronically controlled positioning mechanism to lock the positioning base and sends a loading / unloading signal to the receiving material car.

[0030] The present invention also proposes a control method for a material stack transfer system, including the material preparation method of the above-mentioned horizontally moving material preparation vehicle, wherein, before the steps of receiving the vehicle arrival signal, controlling the bracket locking mechanism to start, and switching the bracket locking mechanism to the locking position, the method further includes:

[0031] Control the transfer car loaded with the empty movable bracket to move to the rear end of the mother car of the adjacent horizontally moving material preparation car;

[0032] Control the transition rail on the connecting car to be lowered and overlapped with the rear end of the mother car body so that the bracket rail on the connecting car body and the daughter car rail on the mother car body can be connected to each other.

[0033] The control bracket push-pull trolley locks the unloaded movable bracket and pushes the unloaded movable bracket to the horizontally moving material preparation trolley.

[0034] In one embodiment, after receiving the child vehicle arrival signal, controlling the bracket locking mechanism to start, and switching the bracket locking mechanism to the locked position, and before receiving the material preparation signal and controlling the material preparation mother car to move the unloaded movable bracket to the preset starting position, the method further includes:

[0035] Control the transition rail of the connecting material car to rise and separate from the body of the mother car.

[0036] After receiving the initial position signal of the mother car and controlling the electronically controlled positioning mechanism to lock the positioning base; before receiving the material preparation completion signal and controlling the material preparation mother car to move the load-bearing movable bracket to the preset endpoint position, the method further includes:

[0037] Upon receiving the loading signal, the overhead crane is controlled to hoist the material rack containing the material to be processed onto the unloaded movable bracket.

[0038] In one embodiment, after the steps of receiving the material preparation completion signal, controlling the electronically controlled positioning mechanism to disengage from the positioning base, controlling the material preparation trolley to move the load movable bracket to a preset endpoint position, and then controlling the electronically controlled positioning mechanism to lock the positioning base, and before the steps of receiving the unlocking signal and controlling the bracket locking mechanism to switch to the unlocked position, the method further includes:

[0039] Control the transfer car to move to the rear of the adjacent horizontally moving material preparation car;

[0040] Control the transition rails on the connecting material car to be lowered and overlapped with the rear end of the mother car body so that the bracket rails on the connecting material car body and the daughter car rails on the mother car body can be connected to each other.

[0041] In one embodiment, after the step of receiving the unlock signal and controlling the bracket locking mechanism to switch to the unlocked position, the method further includes:

[0042] The control bracket push-pull trolley locks and pulls the load movable bracket to move onto the receiving material trolley;

[0043] Control the transition rail of the receiving material car to rise and separate from the body of the mother car;

[0044] Control the material transfer trolley to move to the first preset processing position, and lower the transition guide rail on the material transfer trolley to connect with the steel rail of the processing station.

[0045] The control bracket push-pull trolley pushes the load movable bracket to the processing station, and raises the transition guide rail of the connecting material trolley until it is separated from the steel rail of the processing station;

[0046] Control the material receiving car to move to the second preset processing position, so that the transition guide rail on the material receiving car is lowered and connected to the steel rail of the processing station;

[0047] Control the bracket push-pull trolley to move close to the processing station, so that the bracket push-pull trolley locks the movable bracket of the load and pulls the movable bracket of the load to move onto the connecting material trolley;

[0048] Control the transition rail of the material receiving car to rise and separate from the steel rail of the processing station;

[0049] Upon receiving the material handling signal, the overhead crane is controlled to lift the rack containing the processed material pile to the preset placement position.

[0050] This invention relates to a horizontally movable material preparation trolley, comprising a mother car body, a daughter car track mounted on the mother car body, a bracket limiting mechanism, and a bracket locking mechanism. The bracket limiting mechanism and the bracket locking mechanism are mounted at the head of the mother car body. The mother car body can move horizontally along the extension direction of the ground track, allowing a movable bracket to move horizontally along the extension direction of the daughter car track and connect to it. The movable bracket is equipped with a fastening mechanism, and the bracket limiting mechanism is used to limit and abut the movable bracket in the extension direction of the daughter car track. Thus, after the movable bracket is limited and stopped by the bracket limiting mechanism, the bracket locking mechanism and the fastening mechanism work together to lock and unlock the movable bracket relative to the mother car body. The bracket limiting mechanism achieves precise positioning of the fastening mechanism on the movable bracket and the bracket locking mechanism on the mother car body, eliminating the need for operators to manually move the movable bracket to align the fastening mechanism and the bracket locking mechanism, effectively reducing the workload and operational risks for operators.

[0051] Furthermore, by setting up a control module and a carriage arrival detection element, the control module is used to control the bracket locking mechanism to switch to the locked position after receiving the carriage arrival signal; the control module is also used to control the bracket locking mechanism to switch to the unlocked position when receiving the unlock signal. In this way, by automatically controlling the switching between the locked and unlocked positions of the bracket locking mechanism through the electronic control system, the positioning accuracy of the movable bracket during automatic operation can be guaranteed. Without the need for manual positioning by operators, the workload of operators and the risk of material roll collisions and losses can be greatly reduced, thereby reducing the material stack transportation time, effectively reducing the total processing time, improving production efficiency, and reducing production costs.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application. In addition, the technical solutions of various embodiments can be combined with each other, but this must be based on the ability of those of ordinary skill in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0074] This invention proposes a horizontally moving material preparation vehicle.

[0075] In the embodiments of the present invention, please refer to Figures 1 to 6 The horizontally moving material preparation vehicle 100 includes a material preparation mother vehicle 110, a material preparation daughter vehicle, and an electrical control system. The material preparation mother vehicle 110 includes a mother vehicle body 111, a daughter vehicle track 113 installed on the mother vehicle body 111, a bracket limiting mechanism 113, and a bracket locking mechanism 114. The mother vehicle body 111 can move horizontally along the extension direction of the ground track 300. The mother vehicle body 111 includes a head and a tail located at both ends. The bracket limiting mechanism 113 and the bracket locking mechanism 114 are installed on the head of the mother vehicle body 111. The bracket locking mechanism 114 has a locked position and an unlocked position.

[0076] The material preparation trolley includes a movable bracket 120, which is horizontally connected to the trolley track 113 along the extension direction of the trolley track 113. The movable bracket 120 is provided with a fastening mechanism 121. When the material preparation trolley moves along the trolley track 113 to a preset stationary position, the bracket limiting mechanism 113 limits and abuts against the movable bracket 120 in the extension direction of the trolley track 113. In the locked position, the bracket locking mechanism 114 cooperates with the fastening mechanism 121 to restrict the movement of the movable bracket 120 on the trolley track 113. In the unlocked position, the bracket locking mechanism 114 disengages from the fastening mechanism 121 so that the movable bracket 120 can move toward the rear side of the mother car body 111.

[0077] The electronic control system includes a control module 131 electrically connected to each other and a vehicle positioning detection element 132 electrically connected to the control module 131. The vehicle positioning detection element 132 is used to provide a vehicle positioning signal when the movable bracket 120 abuts against the bracket limiting mechanism 113. The control module 131 is electrically connected to the bracket locking mechanism 114 to control the bracket locking mechanism 114 to switch to the locked position after receiving the vehicle positioning signal. The control module 131 is also used to control the bracket locking mechanism 114 to switch to the unlocked position when receiving the unlocking signal.

[0078] In this embodiment, the ground track 300 is installed on the ground and includes two parallel and spaced-apart steel rails, the extension direction of which is consistent with the length extension direction of the mother car body 111. Specifically, the conveying production line may include a first processing line and a second processing line, which can be a material preparation area and an annealing area, respectively. Of course, the first and second processing lines can also be other processing lines, such as a shearing area, a packaging area, and an unloading area. The ground track 300 spans the first and second processing lines, that is, the ground track 300 extends from the first processing line to the second processing line. This allows the horizontally moving material preparation cart 100 to slide horizontally on the ground track 300 to realize the transfer of materials between the first and second processing lines, thereby shortening the transportation route between the first and second processing lines and improving transportation efficiency. Specifically, the mother car body 111 is roughly a flat, long strip structure. Two rows of opposing wheels that slide with the ground track 300 are installed at the bottom of the mother car body 111. The mother car body 111 is made of steel.

[0079] Specifically, the subcarriage track 113 is installed on the upper surface of the mother car body 111. The subcarriage track 113 includes two parallel and spaced-apart rails, and the extension direction of the rails is consistent with the length extension direction of the mother car body 111. In other embodiments, the subcarriage track 113 may also be provided on the side wall of the mother car body 111. To avoid interference with the movement of the material preparation subcarriage by the bracket limiting mechanism 113 and the bracket locking mechanism 114, the bracket limiting mechanism 113 and the bracket locking mechanism 114 are provided at the head of the mother car body 111, which is usually the feeding end of the material preparation mother car 110.

[0080] The movable bracket 120 adopts a steel structure pallet frame, and the movable bracket 120 can specifically be a long strip plate structure. The movable bracket 120 can specifically include a pallet body and two rows of sub-wheels located below the pallet body. The sub-wheels can be high-temperature resistant rollers. The two rows of sub-wheels correspond to the two rails of the sub-carriage track 113. Specifically, the span between the two rows of sub-wheels can be slightly wider than the span between the two rails of the sub-carriage track 113. When the movable bracket 120 is pushed or pulled by an external force, the sub-wheels roll along the sub-carriage track 113, thereby realizing the horizontal reciprocating movement of the movable bracket 120 on the sub-carriage track 113. Optionally, the sub-carriage wheel includes a wheel body and a limiting piece connected to the inner edge of the wheel body. The outer contour of the limiting piece protrudes from the outer periphery of the wheel body. The wheel body overlaps the upper surface of the sub-carriage rail, and the limiting piece abuts against the inner wall of the rail. This allows the two rows of carriage wheels to limit the offset of the movable bracket 120 relative to the carriage track 113 in the left and right directions through the limiting plate, ensuring the accuracy of the reciprocating movement of the movable bracket 120 on the carriage track 113, and facilitating the alignment and installation of the movable bracket 120 and the carriage track 113.

[0081] The material preparation trolley may also include a material rack, which can be a single-layer rack or a multi-layer rack stacked on top of each other. The rack is used to hold material rolls to be processed or already processed material rolls. In use, an overhead crane is typically used to hoist the rack containing the material rolls onto the movable bracket 120 or from the movable bracket 120 to another location. The rack and the movable bracket 120 can be detachably and fixedly connected by plugging or other means, which are not specifically limited here. The fastening mechanism 121 provided on the movable bracket 120 can specifically be a limiting post, limiting hole, limiting hook, etc., as long as it can cooperate with the bracket locking mechanism 114 to restrict the movement of the movable bracket 120; the structure of the fastening mechanism 121 is not specifically limited here. The fastening mechanism 121 can be located on the side wall of the mother car body 111 or on the end face of the mother car body 111, as long as it does not affect the movement and loading of the movable bracket 120.

[0082] The bracket limiting mechanism 113 and the mother car body 111 can be detachably or non-detachably fixedly connected; no specific limitation is made here. When the material preparation trolley moves along the trolley track 113 to a preset stationary position, the movable bracket 120 also moves to the corresponding preset stationary position. At this time, the bracket limiting mechanism 113 stops and abuts against the movable bracket 120 in the extension direction of the trolley track 113, thus limiting the movable bracket 120 to its extreme position towards the bracket locking mechanism 114, preventing the movable bracket 120 from moving too far on the mother car body 111. It can be understood that when the movable bracket 120 moves towards the bracket limiting mechanism 113, it first abuts against the bracket limiting mechanism 113, and then the bracket locking structure locks the movable bracket 120. To reduce the impact force between the movable bracket 120 and the bracket limiting mechanism 113, a flexible or elastic material can be wrapped around the side of the bracket limiting mechanism 113 facing the movable bracket 120, or the side of the bracket limiting mechanism 113 facing the movable bracket 120 can be made of an elastic cushioning material.

[0083] The bracket locking mechanism 114 can be detachably or non-detachably fixedly connected to the mother car body 111. The bracket limiting mechanism 113 and the bracket locking mechanism 114 can be installed integrally or separately on the mother car body 111. The structure of the bracket locking mechanism 114 can be varied, such as an electric telescopic mechanism with a connecting rod, an electromagnetic pin mechanism, etc., as long as it can switch between the locking and unlocking positions. When the movable bracket 120 moves along the daughter car track 113 and abuts against the bracket limiting mechanism 113, the bracket locking mechanism 114 switches from the unlocked position to the locked position. The bracket locking mechanism 114 cooperates with the fastening mechanism 121 on the mother car body 111 to restrict the movement of the movable bracket 120 locking mechanism 114 on the daughter car track 113. At this point, the movable bracket 120 is locked relative to the mother car body 111. The operator can then operate the overhead crane to hoist the material rack containing the material coil onto the movable bracket 120. The mother car 110 is then moved to the designated position for the next processing step. When the bracket locking mechanism 114 is switched to the unlocked position, the bracket locking mechanism 114 disengages from the fastening mechanism 121. At this time, the bracket locking mechanism 114 will not interfere with the movement of the movable bracket 120, allowing the movable bracket 120 to move along the daughter car track 113 towards the side away from the bracket limiting mechanism 113 (the rear side of the mother car body 111). The movable bracket 120 can then be transferred to other material cars or the annealing furnace.

[0084] The bracket positioning detection element can specifically be a position sensor, pressure sensor, or similar structure. The electrical control system may further include a cabinet and cables. The cabinet can be installed on the mother car body 111, and the control module 131 is electrically connected to the bracket positioning detection element and the bracket locking mechanism 114 via cables. The bracket positioning detection element can be specifically positioned directly below the buffer block of the bracket limiting mechanism 113. The bracket positioning detection element provides a vehicle positioning signal to the electrical control system when the movable bracket 120 abuts against the bracket limiting mechanism 113. Upon receiving the vehicle positioning signal, the electrical control system controls the bracket locking mechanism 114 to switch from the unlocked position to the locked position, thereby locking the movable bracket 120 and preventing movement of the movable bracket 120 on the mother car body 111. By setting the bracket positioning detection element, the electrical control system switches the bracket locking mechanism 114 to the locked position based on the vehicle positioning signal from the bracket positioning detection element, automatically locking the movable bracket 120 upon positioning.

[0085] In actual operation, after the horizontally moving material preparation trolley 100, loaded with idle movable bracket 120, moves to the designated starting position in the slitting workshop, the operator uses an overhead crane to hoist the rack containing aluminum foil rolls to be annealed onto the movable bracket 120. Once enough aluminum coils for one annealing furnace cycle have been hoisted, the operator clicks the "Material Preparation Complete" button. After receiving the "Material Preparation Complete" signal, the electrical control system controls the horizontally moving material preparation trolley 100 to automatically move along the ground track 300 towards the annealing workshop until the electrical control system detects the endpoint position signal and stops the movement.

[0086] After the annealing furnace charge car moves to the overlapping end of the horizontally moving material preparation car 100, it stops. The transition guide rail 210 on the annealing furnace charge car is lowered and overlaps with the upper plane 111 of the overlapping end of the mother car body of the horizontally moving material preparation car 100, so that the bracket slide rail on the annealing furnace charge car is flush with the daughter car track 113 of the horizontally moving material preparation car 100. After the electrical control system of the horizontally moving material preparation car 100 detects that the transition guide rail 210 is in place, it controls the bracket locking mechanism 114 and the movable bracket 12. When the zero-phase separation occurs, the annealing furnace material car's support trolley moves close to the electrical control system and stops. The tray hook on the support trolley locks the movable support 120 on the electrical control system. Under the guidance of the support trolley, the movable support 120 is completely transferred from the mother car body 111 to the annealing furnace material car. Then, the transition guide rail 210 is raised and disengaged from the daughter car track 113 of the electrical control system. At this point, the rack loaded with aluminum coils to be annealed has achieved complete transfer from the slitting workshop to the annealing furnace material car.

[0087] Therefore, the unlocking signal for the control bracket locking mechanism 114 to switch to the unlocked position can have at least two sources. For example, when the transition guide rail 210 on the annealing furnace charge car is attached to the rear of the mother car body 111 of the horizontally moving material preparation car 100, the unlocking signal can be issued by the operator manually operating the button. Of course, a guide rail positioning detection element 133 can also be set on the mother car body 111 to automatically issue an unlocking signal when the transition guide rail 210 on the annealing furnace charge car is attached to the mother car body 111 of the horizontally moving material preparation car 100. The source of the unlocking signal is not specifically limited here. The automatic switching between the locking and unlocking positions of the control bracket locking mechanism 114 is achieved through the cooperation of the control module 131 and the sub-car positioning detection element 132. This eliminates the need for operator intervention, significantly reducing the operator's workload. It also ensures the positioning accuracy of the movable bracket 120 during automatic operation, eliminating the need for manual positioning and significantly reducing the operator's workload and the risk of material coil damage and loss.

[0088] The present invention provides a horizontally movable material preparation vehicle 100, wherein the material preparation mother vehicle 110 includes a mother vehicle body 111, a daughter vehicle track 113 mounted on the mother vehicle body 111, a bracket limiting mechanism 113 and a bracket locking mechanism 114, the bracket limiting mechanism 113 and the bracket locking mechanism 114 being mounted on the head of the mother vehicle body 111; the mother vehicle body 111 can move horizontally along the extension direction of the ground track 300, such that the movable bracket 120 can be horizontally connected to the daughter vehicle track 113 along the extension direction of the daughter vehicle track 113, the movable bracket 120 is provided with a fastening mechanism 121, and the bracket limiting mechanism 113 is used to limit and abut against the movable bracket 120 in the extension direction of the daughter vehicle track 113. Thus, after the movable bracket 120 is limited and stopped by the bracket limiting mechanism 113, the movable bracket 120 is locked and unlocked relative to the mother car body 111 by the cooperation of the bracket locking mechanism 114 and the fastening mechanism 121. The bracket limiting mechanism 113 is used to achieve precise positioning of the fastening mechanism 121 on the movable bracket 120 and the bracket locking mechanism 114 on the mother car body 111. There is no need for the operator to manually move the movable bracket 120 to align the fastening mechanism 121 and the bracket locking mechanism 114, which can effectively reduce the workload of the operator and the operational risks.

[0089] Furthermore, by setting up a control module 131 and a carriage arrival detection element 132, the control module 131 is used to control the bracket locking mechanism 114 to switch to the locked position after receiving the carriage arrival signal; the control module 131 is also used to control the bracket locking mechanism 114 to switch to the unlocked position when receiving the unlocking signal. In this way, by automatically controlling the switching between the locked and unlocked positions of the bracket locking mechanism 114 through the electronic control system, the positioning accuracy of the movable bracket 120 during automatic operation can be guaranteed. Without the need for manual positioning by the operator, the workload of the operator and the risk of material roll collision damage and loss can be greatly reduced, thereby reducing the material stack transportation time, effectively reducing the total processing time, improving production efficiency, and reducing production costs.

[0090] Furthermore, the electronic control system also includes a mother car positioning detection element electrically connected to the control module 131, which provides a mother car positioning signal when the mother car body 111 moves to a preset position; the material preparation mother car 110 also includes an electronically controlled positioning mechanism 115 electrically connected to the control module 131, which is fixedly installed on the mother car body 111. The control module 131 is also used for:

[0091] Upon receiving the signal that the mother car has arrived, the electronically controlled positioning mechanism 115 locks itself to the positioning base 400 on the ground; and

[0092] Upon receiving the transfer signal, the control electronic positioning mechanism 115 disengages from the positioning base 400.

[0093] In this embodiment, the positioning base 400 is fixedly installed on the ground. Specifically, the positioning base 400 can be a positioning sleeve, a concrete structure, a steel structure, or other structures. The electronic control system can control the electronic positioning mechanism 115 to switch between a locked position and an unlocked position. In the locked position, the electronic positioning mechanism 115 is locked to the positioning base 400 on the ground to lock the horizontally moving material preparation vehicle 100 to the ground, preventing it from moving. In the unlocked position, the electronic positioning mechanism 115 disengages from the positioning base 400, at which point the electronic control system can control the mother car body 111 to move relative to the ground. The positioning structure can have many structures, such as a telescopic sleeve structure or an electromagnetic pin structure, etc., and is not specifically limited here. After the material preparation mother car 110 moves into position, the electrical control system, upon receiving a stop signal from the mother car, controls the positioning structure to switch to the locked position, locking the positioning mechanism to the positioning base 400 to prevent displacement of the material preparation mother car 110.

[0094] The mother car arrival detection element can be a position sensor, pressure sensor, or similar structure. It can be installed at a preset position on the ground track 300 or on other structures, as long as it can issue a mother car arrival signal when the preparation mother car 110 reaches the preset position. This transfer signal can be issued by the operator via an operation button or automatically by the horizontally moving preparation car 100 interacting with other material cars; there are no limitations on this. Upon receiving the transfer signal, the control electrical positioning mechanism 115 disengages from the positioning base 400, and the electrical control system can then control the mother car body 111 to move to the desired position. By detecting the movement position of the preparation mother car 110 through the mother car arrival detection element, the electrical control system can automatically control the start and stop of the preparation mother car 110, eliminating the need for manual operation and significantly reducing the operator's workload.

[0095] Furthermore, please refer to the following: Figure 7 The material preparation mother car 110 also includes traveling wheels 117 and a drive mechanism 116. The traveling wheels 117 are installed at the bottom of the mother car body 111 and are horizontally connected to the ground track 300 along the extension direction of the ground track 300. The traveling wheels 117 include a drive wheel 118 and a driven wheel 119. The drive mechanism 116 is used to drive the drive wheel 118 to rotate. The drive mechanism 116 is electrically connected to the control module 131. The control module 131 is also used to control the drive mechanism 116 to drive the drive wheel 118 to move the mother car body 111 after receiving a transfer signal.

[0096] In this embodiment, the driving wheel 118 and driven wheel 119 can be configured as one or more pairs. Typically, the driving wheel 118 is configured as one pair, and the driven wheel 119 is configured as multiple pairs. The drive mechanism 116 may specifically include a drive motor acceleration and deceleration structure. The drive mechanism 116 drives the driving wheel 118 to rotate, and the driven wheel 119 supports the mother car body 111 and assists in movement. In use, the drive mechanism 116 is automatically controlled by the electronic control system to drive the driving wheel 118 to rotate, thereby controlling the overall movement of the material preparation mother car 110. No manual operation by the operator is required, which can significantly reduce the workload of the operator.

[0097] In one embodiment, the electronic control system further includes a guide rail positioning detection element 133 and / or a communication module electrically connected to the control module 131. The guide rail positioning detection element 133 is used to provide an unlocking signal when the transition guide rail 210 of the connecting material trolley 200 is attached to the rear of the mother car body 111. The communication module is used to transmit a transfer signal to the control module 131 after receiving a material preparation completion signal, and to send a loading and unloading signal to the connecting material trolley 200 when the electronic positioning mechanism 115 is locked with the positioning base 400.

[0098] The guide rail positioning detection element 133 can specifically be a position sensor, pressure sensor, or similar structure. The control module 131 can be electrically connected to the guide rail positioning detection element 133 via a cable. By setting the guide rail positioning detection element 133, the electrical control system controls the bracket locking mechanism 114 to switch to the unlocked position based on the unlocking signal from the guide rail positioning detection element 133, so that the horizontally moving material preparation cart 100 automatically unlocks after moving into position. In this way, there is no need for manual operation to transmit the unlocking signal, which can improve the automation level of the production line, thereby significantly reducing the workload of operators and improving production efficiency.

[0099] The communication module can communicate with external systems wirelessly, such as using 5G, or via wired communication; specific limitations are not provided here. By setting up the communication module, interaction between the electrical control system and other external material carts can be achieved. The connecting material cart 200 can be an annealing furnace material cart, or other material carts, such as packaging material carts, slitting material carts, overhead cranes, etc. The communication module transmits a transfer signal to the control module 131 after receiving a material preparation completion signal. When the electrical control positioning mechanism 115 is locked to the positioning base 400, it sends a loading / unloading signal to the connecting material cart 200. Upon receiving the loading / unloading signal, the connecting material cart 200 can automatically move to the vicinity of the horizontally moving material preparation cart 100, realizing material transfer between them. In this way, the horizontally moving material preparation vehicle 100 can interact with the connecting material vehicle 200 through the communication module without the need for manual operation by the operator, making the entire production line more intelligent. This can significantly reduce the workload of the operators and the risk and loss of material rolls from collisions, thereby reducing the material stack transportation time, effectively reducing the total processing time, improving production efficiency, and reducing production costs.

[0100] The present invention also proposes a material preparation method for a horizontally moving material preparation vehicle. This material preparation method is applied to the above-mentioned horizontally moving material preparation vehicle. The specific structure of the horizontally moving material preparation vehicle is as described in the above embodiments. Since the material preparation method of this horizontally moving material preparation vehicle adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated here.

[0101] To facilitate the explanation of the material preparation methods and procedures for horizontally moving material preparation carts, the following description uses the operational flow of aluminum foil rolls in the slitting workshop and the return workshop as an example. For instance... Figure 10 As shown, the material preparation method of the horizontally moving material preparation vehicle includes:

[0102] Step S10: Receive the vehicle arrival signal, control the bracket locking mechanism to start, and switch the bracket locking mechanism to the locking position.

[0103] When the movable bracket comes into contact with the bracket limiting mechanism, the trolley positioning detection element provides a trolley positioning signal to the control module. Upon receiving the signal, the control module activates the bracket locking mechanism to switch it from the unlocked position to the locked position, thereby locking the movable bracket to the mother car body and enabling operations such as hoisting material racks. In other embodiments, the bracket locking mechanism can also be switched to the locked position by de-energizing it.

[0104] Step S40: Receive the unlock signal and control the bracket locking mechanism to switch to the unlock position.

[0105] In this embodiment, the unlocking signal can have at least two sources. For example, when the transition guide rail 210 on the annealing furnace material car overlaps with the rear of the mother car body 111 of the horizontally moving material preparation car 100, the operator can manually operate a button to send an unlocking signal. Alternatively, a guide rail positioning detection element 133 can be installed on the mother car body 111 so that when the transition guide rail 210 on the connecting material car overlaps with the rear of the mother car body 111 of the horizontally moving material preparation car 100, the guide rail positioning detection element automatically sends an unlocking signal to the control module. The source of the unlocking signal is not specifically limited here. By controlling the bracket locking mechanism to switch from the locked position to the unlocked position, the movable bracket can move towards the rear of the mother car body, that is, the movable bracket can be moved from the material preparation mother car to the connecting material car, thus realizing the transfer of the movable bracket between the horizontally moving material preparation car and the connecting material car. By controlling the locking mechanism of the bracket through the arrival signal of the trolley and unlocking it through the unlocking signal, the precise switching of the bracket locking mechanism can be achieved, which helps to reduce the material stack transportation time, effectively reduce the total processing time, and improve production efficiency.

[0106] Further, please refer to Figure 11 Between receiving the vehicle arrival signal, steps S10 and S40 further include:

[0107] Step S20: Receive the material preparation signal and control the material preparation mother car to move the unloaded movable bracket to the preset starting position.

[0108] The material preparation signal can be issued by the operator clicking the "Prepare Material" button, or it can be automatically issued by the interaction between the horizontally moving material preparation cart and other material carts; this is not limited to either. After the bracket locking mechanism switches to the locked position, locking the unloaded movable bracket to the mother car body, the traveling vehicle of the material preparation mother car is controlled to rotate, thereby moving the unloaded movable bracket to the preset starting position to enter the "Prepare Material" operation. This preset starting position can specifically be a designated location in the slitting workshop.

[0109] Step S30: Receive the material preparation completion signal and control the material preparation mother car to move the movable bracket of the load to the preset end position.

[0110] In this embodiment, when the horizontally moving material preparation trolley reaches the preset starting position, a loading operation can be performed. For example, an operator can use an overhead crane to hoist the material rack containing the material to be processed onto the movable bracket. After enough coils of material have been hoisted, the operator can click the "Material Preparation Complete" button. That is, the material preparation complete signal can be issued by the operator clicking the "Material Preparation Complete" button. Of course, the material preparation complete signal can also be automatically issued by the interaction between the horizontally moving material preparation trolley and the overhead crane, which is not specifically limited here. Upon receiving the material preparation complete signal, the material preparation mother trolley is controlled to drive the loaded movable bracket along the ground track to the preset endpoint position. The preset endpoint position can specifically be a designated position in the return workshop. In this way, the transfer between the two processing workshops of the horizontally moving material preparation trolley is completed.

[0111] Furthermore, such as Figure 12 As shown, step S20 specifically includes:

[0112] Step S21: Receive the material preparation signal, control the electronically controlled positioning mechanism to disengage from the positioning base, control the material preparation mother car to move the unloaded movable bracket to the preset starting position, receive the mother car starting position arrival signal, and control the electronically controlled positioning mechanism to lock the positioning base.

[0113] Step S30 specifically includes:

[0114] Step S31: Receive the material preparation completion signal, control the electronically controlled positioning mechanism to disengage from the positioning base, control the material preparation mother car to move the load's movable bracket to the preset end position, receive the mother car end position arrival signal, and control the electronically controlled positioning mechanism to lock the positioning base.

[0115] In this embodiment, upon receiving the material preparation signal, the electronic control system controls the electronically controlled positioning mechanism to disengage from the positioning base, allowing the material preparation trolley to move relative to the ground. Once the material preparation trolley, carrying the unloaded movable bracket, moves to the preset starting position, the trolley positioning detection element is triggered, sending a starting position signal. At this point, by controlling the electronically controlled positioning mechanism to lock the positioning base, the material preparation trolley is locked relative to the ground, preventing displacement of the trolley during material preparation and thus avoiding safety hazards.

[0116] Further, please refer to Figure 13 Step S21 specifically includes:

[0117] Step S211: Receive the material preparation signal, control the electronically controlled positioning mechanism to disengage from the positioning base, control the drive mechanism to drive the drive wheel to rotate, so as to move the mother car body loaded with the empty movable bracket to a preset starting position, and then receive the mother car starting position arrival signal to control the electronically controlled positioning mechanism to lock the positioning base.

[0118] Step S31 specifically includes:

[0119] Step S311: Receive the material preparation completion signal, transmit the transfer signal to the control module 131, control the electronically controlled positioning mechanism to disengage from the positioning base, control the drive mechanism to drive the drive wheel to rotate, so as to move the mother car body with the load-bearing movable bracket to a preset end position, receive the end position arrival signal of the mother car, control the electronically controlled positioning mechanism to lock the positioning base, and send the loading and unloading signal to the connecting material car.

[0120] In this embodiment, the material preparation process is as follows: After the horizontally moving material preparation trolley loaded with an empty movable bracket moves to the designated starting position in the slitting workshop, the control electrical positioning mechanism locks the horizontally moving material preparation trolley to prevent it from shifting relative to the ground; the operator operates the overhead crane to hoist the material rack containing the aluminum foil rolls to be annealed onto the movable bracket 120. After hoisting enough aluminum coil material racks for one annealing furnace cycle, the operator clicks the "Material Preparation Complete" button.

[0121] The transfer process is as follows: After receiving the "material preparation complete" signal, the electrical control system controls the electrical control positioning mechanism to disengage from the positioning base, causing the horizontally moving material preparation cart to disengage from its locked state. Then, it controls the drive mechanism to drive the drive wheel to rotate, causing the horizontally moving material preparation cart to automatically move along the ground track towards the unloading workshop until the electrical control system detects the mother car's endpoint position signal and stops the movement. At this time, the electrical control system controls the electrical control positioning mechanism to lock the horizontally moving material preparation cart to prevent it from shifting relative to the ground. Thus, the next step of the furnace loading and unloading process can proceed. When material preparation and unloading are required, locking the electrical control positioning mechanism to the positioning base ensures the horizontally moving material preparation cart is locked relative to the ground, guaranteeing operational safety. When transfer is required, the locking state of the electrical control positioning mechanism is automatically released, achieving automatic start-stop locking of the horizontally moving material preparation cart. This high degree of automation helps reduce material pile transportation time, effectively reducing the total processing time and improving production efficiency.

[0122] This invention also proposes a control method for a stockpile transfer system, including the material preparation method of the horizontally moving material preparation vehicle described above, which refers to the above embodiments. The material preparation method of the horizontally moving material preparation vehicle is applied to the above-described horizontally moving material preparation vehicle, and the specific structure of the horizontally moving material preparation vehicle refers to the above embodiments. Since the control method of this stockpile transfer system adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated here.

[0123] like Figures 10 to 14 As shown, in the control method of the stockpile transfer system, the method further includes the following steps before step S10:

[0124] Step S01: Control the connecting material car loaded with the empty movable bracket to move to the rear end of the preparation mother car adjacent to the horizontally moving preparation car;

[0125] Step S02: Control the transition rail on the connecting material car to be lowered and overlapped to the rear end of the mother car body so that the bracket rail on the connecting material car body and the daughter car rail on the mother car body can be connected to each other.

[0126] Step S03: Control the bracket push-pull trolley to lock the unloaded movable bracket 120, and push the unloaded movable bracket 120 to move onto the horizontally moving material preparation trolley.

[0127] In this embodiment, the connecting material cart can be an annealing furnace material cart, a packaging material cart, a slitting material cart, etc. For ease of explanation, the connecting material cart will be described exemplarily as an annealing furnace material cart. The pre-preparation operation process is as follows: The annealing furnace material cart loaded with an empty movable bracket moves to the rear (discharge end) of the horizontally moving material preparation cart and stops. At this time, the position of the annealing furnace material cart can be detected by a detection element, and an annealing furnace material cart arrival signal is issued after the annealing furnace material cart loaded with an empty movable bracket moves to the rear (discharge end) of the horizontally moving material preparation cart. At this time, the transition guide rail of the annealing furnace material cart can be automatically lowered. Of course, the transition guide rail on the annealing furnace material cart can also be lowered or raised manually by the operator.

[0128] The transition guide rail on the annealing furnace charge car is lowered and connected to the upper surface of the discharge end of the mother car body of the horizontally moving material preparation car, so that the bracket rail on the annealing furnace charge car is neatly aligned with the daughter car rail on the horizontally moving material preparation car. The pallet hook on the bracket push-pull trolley locks the idle movable bracket 120 on the annealing furnace charge car. The bracket push-pull trolley moves towards the horizontally moving material preparation car. Under the push of the bracket push-pull trolley, the empty movable bracket is completely transferred from the annealing furnace charge car to the horizontally moving material preparation car. When the movable bracket moves along the daughter car rail to the bracket limit mechanism, the daughter car arrival detection element provides a daughter car arrival signal to the control module. After receiving the daughter car arrival signal, the control module controls the bracket locking mechanism to start, so as to switch the bracket locking mechanism from the unlocked position to the locked position, thereby realizing the locking between the movable bracket and the mother car body.

[0129] Further, please refer to Figure 15 Between steps 10 and 20, the following also applies:

[0130] Step S11: Control the transition guide rail of the connecting material car to rise and separate from the body of the mother car.

[0131] The process between steps S21 and S30 also includes:

[0132] Step 210: Receive the loading signal and control the overhead crane to hoist the material rack containing the material pile to be processed onto the unloaded movable bracket 120.

[0133] In this embodiment, after receiving the signal that the subcart has arrived, the control mechanism of the bracket locking mechanism is activated and switched to the locked position. The transition guide rail on the annealing furnace material car is raised and disengaged from the subcart track of the horizontally moving material preparation car. The operator clicks the "Prepare Material" button. After receiving the "Prepare Material" signal, the electronic control system controls the wheels of the horizontally moving material preparation car to rotate, so that the horizontally moving material preparation car moves to the designated starting position in the slitting workshop and enters the "Prepare Material" operation stage.

[0134] Upon receiving the material preparation signal, the operator controls the electronically controlled positioning mechanism to disengage from the positioning base. The material preparation trolley then moves the unloaded movable bracket to a preset starting position. Upon receiving the trolley's starting position signal, the operator controls the electronically controlled positioning mechanism to lock the positioning base. At this point, the operator can send a loading signal to the overhead crane via a button, or the loading signal can be automatically sent after the electronically controlled positioning mechanism locks with the positioning base; no specific limitation is made here. Upon receiving the loading signal, the operator controls the overhead crane to hoist the rack containing the material pile to be processed (aluminum foil rolls to be annealed) onto the unloaded movable bracket 120. Once enough aluminum coils for one annealing furnace cycle have been hoisted, the operator clicks the "Material Preparation Complete" button, at which point the movable bracket 120 is fully loaded.

[0135] Furthermore, please refer to the following: Figure 16 Between steps 31 and 40, the following also applies:

[0136] Step 310: Control the connecting material trolley to move to the rear end of the adjacent horizontally moving material preparation trolley;

[0137] Step 320: Control the transition rail on the connecting material car to be lowered and overlapped with the rear end of the mother car body so that the bracket rail on the connecting material car body and the daughter car rail on the mother car body can be connected to each other.

[0138] In this embodiment, the operator can send a material pick-up signal to the receiving material trolley via a button, or the signal can be sent after the electronically controlled positioning mechanism locks the positioning base upon receiving a signal indicating the mother trolley has reached its destination. This is not specifically limited. Upon receiving the pick-up signal, the control system of the material stack transfer system controls the receiving material trolley to move to the rear end of the adjacent horizontally moving mother trolley, thus automatically moving the receiving material trolley to the rear end of the adjacent horizontally moving mother trolley.

[0139] The transition guide rail on the receiving car is lowered by a detection element that monitors the position of the annealing furnace car. Once the annealing furnace car has moved to the rear (discharge end) of the horizontally moving material preparation car, a signal indicating that the annealing furnace car has reached its position is issued. At this point, the transition guide rail on the annealing furnace car can be automatically lowered. Alternatively, the transition guide rail on the annealing furnace car can be lowered or raised manually by the operator.

[0140] The furnace loading and unloading process is as follows: After the annealing furnace material car moves to the rear (discharge end) of the horizontally moving material preparation car, it stops. The transition guide rail on the annealing furnace material car is lowered and connected to the upper surface of the mother car body of the horizontally moving material preparation car, so that the bracket rail on the annealing furnace material car is neatly connected with the daughter car rail on the horizontally moving material preparation car.

[0141] In one embodiment, such as Figure 17 As shown, step 40 is followed by:

[0142] Step 51: Control the bracket push-pull trolley to lock and pull the load movable bracket 120 to move onto the receiving material cart;

[0143] Step 52: Control the transition guide rail of the receiving material car to rise and separate from the body of the mother car;

[0144] Step 53: Control the material receiving trolley to move to the first preset processing position, and lower the transition guide rail on the material receiving trolley to connect with the steel rail of the processing station;

[0145] Step 54: Control the bracket push-pull trolley to move the load movable bracket 120 to the processing station, and raise the transition guide rail of the connecting material trolley until it is disengaged from the steel rail of the processing station.

[0146] In this embodiment, the processing station can be an annealing furnace, a tempering furnace, a slitting station, or a packaging station, etc. For ease of explanation, the following description uses the material receiving car as the annealing furnace material car and the processing station as the annealing chamber as an example. The furnace loading and unloading process also includes: the bracket track on the annealing furnace material car is neatly aligned with the subcarriage track on the horizontally moving material preparation car. After the electrical control system of the horizontally moving material preparation car detects that the transition guide rail is in place, it controls the bracket locking mechanism to disengage from the movable bracket. The bracket push-pull trolley of the annealing furnace material car will move until it approaches the horizontally moving material preparation car and then stops (this can be operated by an operator or automatically controlled after the detection element sends a signal to indicate that it is in place). The pallet hook on the bracket push-pull trolley locks the fully loaded movable bracket on the horizontally moving material preparation car. After the movable bracket is completely transferred from the horizontally moving material preparation car to the annealing furnace material car under the guidance of the bracket push-pull trolley, the transition guide rail is raised and disengaged from the subcarriage track of the horizontally moving material preparation car. At this point, the rack loaded with aluminum coils to be annealed has achieved complete transfer from the slitting workshop to the annealing furnace material car.

[0147] The movement signal of the connecting material cart can be issued by the operator or automatically by the detection element. The furnace loading process is as follows: The annealing furnace material cart moves to the designated annealing furnace. After reaching the designated position (first preset processing position), the transition guide rail is lowered so that the transition rail on the annealing furnace material cart is neatly aligned with the steel rail inside the annealing furnace. Then, under the push of the annealing furnace material cart bracket push-pull trolley, the movable bracket carrying the aluminum coil rack to be annealed is completely moved along the trolley track to the steel rail inside the annealing furnace and then enters the annealing furnace chamber. After that, the transition guide rail is raised and disengaged from the steel rail inside the annealing furnace, the furnace door is lowered, and the annealing furnace is started to carry out the annealing operation.

[0148] Step 61: Control the material receiving trolley to move to the second preset processing position, so that the transition guide rail on the material receiving trolley is lowered and connected to the steel rail of the processing station;

[0149] Step 62: Control the bracket push-pull trolley to move close to the processing station, so that the bracket push-pull trolley locks the movable bracket 120 of the load and pulls the movable bracket 120 of the load to move onto the receiving material trolley;

[0150] Step 63: Control the transition guide rail of the material receiving car to rise and disengage from the steel rail of the processing station;

[0151] Step 64: Receive the material picking signal and control the overhead crane to lift the rack containing the processed material pile to the preset placement position.

[0152] In this embodiment, the movement signal of the connecting material cart can be issued by the operator or automatically by the detection element. The unloading process is as follows: the annealing furnace material cart moves to the designated annealing furnace. After reaching the designated position (second preset processing position), the annealing furnace door is raised, and the annealing furnace material cart lowers the transition guide rail, so that the bracket slide rail on the annealing furnace material cart is neatly aligned with the steel rail inside the annealing furnace. The bracket push-pull trolley of the annealing furnace material cart will move towards the annealing furnace chamber until it is close to the annealing furnace door and then stops (this can be operated by the operator or automatically controlled after the detection element issues a positioning signal). The tray hook on the bracket push-pull trolley will hold the trays on the steel rail inside the annealing furnace that are equipped with the material. After annealing, the movable bracket of the material pile is locked. Under the guidance of the bracket push-pull trolley, the movable bracket 120 is completely transferred from the annealing furnace to the annealing furnace material car. The transition guide rail is raised and disengaged from the steel rail in the annealing furnace. The operator operates the overhead crane to lift the rack containing the annealed aluminum coils from the movable bracket on the annealing furnace material car to the special aluminum coil cooling and packaging area for further processing. After completion, the movable bracket 120 on the annealing furnace material car changes from a fully loaded state to an empty state, and the next aluminum coil production turnover cycle can begin.

[0153] By employing the horizontally moving material preparation car, its material preparation method, and the control method of the material stack transfer system of this invention for material rack operation, under the same monthly production of 5,000 tons of aluminum foil, 840 cross-span transfers and 840 overhead crane hoists are reduced per month. Each saved transfer and hoisting operation takes a total of 15 minutes, translating to a reduction of 12,600 minutes (210 hours) of transfer and hoisting operation time per month. This translates to reduced downtime for the annealing furnace awaiting material. Besides reducing energy consumption and personnel costs associated with overhead crane and cross-span car operation, based on a single furnace charge of 30 tons, an annealing time of 150 hours, and a gross profit of 12,500 yuan / ton for aluminum foil processing, this equates to an increase in profit of over 500,000 yuan per month and 6 million yuan per year, demonstrating significant economic benefits. Furthermore, by reducing the number of transfers and hoisting operations, the workload of operators and the risk of damage and losses from aluminum coil impacts are also significantly reduced.
