Description

Technical Field

[0001] The present invention relates to the technical field of workshop coil material logistics, and in particular to a coil material logistics system and an operating method in a production workshop, which is low in cost, simple in coil material logistics procedure, convenient in coil material circulation and high in circulation efficiency. Background Art

[0002] Mechanization and automation are the development directions of modern factories. Many types of raw materials, including printing raw materials, raw materials for lithium battery / copper foil / power diaphragm production lines, are stored / transported in the form of coils. At present, coils are generally placed on pallets in a vertical state during storage to avoid damage to the surface layer of the coils due to pressure. However, subsequent factory processes generally require the coils to be in a horizontal state. Therefore, the coils need to be unpacked, rolled up, and then stored in a cache in a horizontal manner. When the coils need to be replaced, a piggyback AGV vehicle is generally used (such as a two-stage lifting device and automatic guided transport vehicle disclosed in CN115092857A, a piggyback AGV specially used for horizontal film and paper roll transportation disclosed in CN213011031U, and a suitable for automatic The coil lifting device of the three-dimensional warehouse, the fully automatic coil handling AGV robot disclosed in CN108861514A, and the coil lifting AGV disclosed in CN217458699U are all piggyback AGV vehicles) for transportation. There are also those that directly use clamping forklifts to directly complete the coil rolling and transportation, but the use scenarios of piggyback AGV vehicles are relatively limited, that is, to fully meet the use needs of the factory, it needs to be used in conjunction with other types of AGVs. At the same time, the piggyback AGV vehicle also needs to be used with a special rolling device, which greatly increases the operating cost of the factory and the difficulty of factory scheduling. Although the clamping forklift can directly complete the coil rolling and transportation, it is not only large in size, which affects the layout in the factory, that is, the factory space utilization rate is low, but also requires an operator to drive, and the operating cost is high.

[0003] Therefore, it is of great practical significance to develop a coil material logistics system in a production workshop with a reasonable overall design, simple structure, simplified coil material logistics procedures, convenient mechanical operation and high circulation efficiency. Summary of the invention

[0004] Due to the above-mentioned defects in the prior art, the present invention provides a coil material logistics system and an operation method for a production workshop with low cost, simple coil material logistics procedures, convenient coil material circulation and high circulation efficiency, so as to overcome the defects of complex coil material logistics procedures in the workshop, the need for coordination of multiple devices, low degree of automation, low circulation efficiency and high operating cost.

[0005] In order to achieve the above object, the present invention provides the following technical solutions:

[0006] A production workshop coiled material logistics system, including a stacking AGV vehicle for coiled materials and a drive-in rack for coiled materials;

[0007] The stacking AGV vehicle for coiled materials includes an AGV shell, two legs, and a lifting fork frame;

[0008] The AGV shell is fixedly connected to the two legs. The two legs are parallel to each other and arranged at intervals. Shell wheels are installed on the lower side of the AGV shell, and leg wheels are installed on the lower side of the legs;

[0009] The lifting fork frame is arranged on the side of the AGV shell where the legs are installed. A fork frame lifting device connected to the lifting fork frame and used to drive the lifting fork frame to lift is installed on the AGV shell. The lifting fork frame includes a lifting plate, two transfer rods, and two lifting support rods. The lifting plate is connected to the fork frame lifting device. The arrangement direction of the lifting support rods is parallel to the legs. The lifting support rods are fixedly connected to the vertically arranged lifting plate through the transfer rods. The lifting plate, the two transfer rods, and the two lifting support rods form a U-shaped structure. Matching support rod coiled material shaft fixing grooves for fixing the coiled material shaft are opened on the two lifting support rods;

[0010] The distance between the center position of the support rod coiled material shaft fixing groove and the shell wheel is less than the distance between the center position of the leg wheel and the shell wheel, so as to improve the stability of the AGV vehicle during operation (specifically, to avoid the AGV vehicle from tipping over when the lifting fork frame lifts);

[0011] The drive-in rack for coiled materials includes multiple vertically arranged support frames;

[0012] The multiple support frames are parallel to each other and arranged at intervals. A horizontally arranged fixing frame is installed on the top of the support frame, and the fixing frame is simultaneously fixed to at least two support frames;

[0013] The support frame includes multiple horizontal bars and multiple vertical bars that are perpendicularly connected to each other. The multiple horizontal bars and vertical bars enclose a grid-shaped support frame. The vertical bars are vertically arranged and the horizontal bars are horizontally arranged. Coiled material shaft fixing grooves for fixing the coiled material shaft are provided on the horizontal bars, and the coiled material shaft fixing grooves on adjacent support frames match each other;

[0014] The distance between adjacent support frames is greater than the width of the stacking AGV vehicle for coiled materials and less than the length of the coiled material shaft.

[0015] The in-plant coiled material logistics system of the present invention has a reasonable overall design. It uses a stacking AGV for coiled materials in cooperation with a drive-in rack for coiled materials. The drive-in rack for coiled materials changes the current vertical storage form to a horizontal storage form, eliminating the original operation of turning the coiled materials in the workshop, which can greatly improve the transfer efficiency of coiled materials in the workshop. At the same time, the rack adopts a drive-in design. When the stacking AGV for coiled materials reaches a certain height, it drives into the rack between adjacent support frames. After the coiled material shafts are basically aligned with the coiled material shaft fixing grooves, the height of the coiled materials is lowered so that the coiled material shafts are clamped into the coiled material shaft fixing grooves, completing the storage of the coiled materials (the coiled material feeding and discharging operation process is similar). The operation is simple, and the loading and unloading can be quickly completed. The overall structure of the rack is simple and has good stability (the coiled materials are supported by the support frames on both sides), enabling the full mechanization and full automation of the transfer of coiled materials in the workshop. The structure of the stacking AGV for coiled materials is reasonably designed and relatively simple. The support rod coiled material shaft fixing grooves provided on the lifting fork can effectively fix the coiled material shafts, preventing the coiled material shafts from shaking during operation. At the same time, the support rod coiled material shaft fixing grooves are closer to the outer shell wheels than the leg wheels, which can greatly improve the stability of the AGV during lifting operations. It can be obtained by simply modifying the existing stacking AGV (welding the lifting fork), with low cost, good applicability, and the effect of multi-purpose use, which can reduce the operation cost of the factory and has high overall operation efficiency and good application prospects.

[0016] As a preferred technical solution:

[0017] For the in-plant coiled material logistics system as described above, the coiled material shaft fixing groove on the rack or the support rod coiled material shaft fixing groove is a V-shaped groove, a U-shaped groove, a C-shaped groove, or a trapezoidal groove, and its shape can be selected according to actual needs. Of course, the purpose of the fixing groove design is to fix the round rod-shaped coiled material shaft in the groove to prevent it from shaking.

[0018] For the in-plant coiled material logistics system as described above, the width of the coiled material is less than the distance between the two lifting support rods, and the length of the coiled material shaft is greater than the distance between the two lifting support rods;

[0019] The length of the coiled material shaft is less than M + 2N, where M is the distance between adjacent support frames and N is the length of the coiled material shaft fixing groove on the rack. The length direction of the coiled material shaft fixing groove on the rack is perpendicular to the plane where the support frames are located.

[0020] For the in-plant coiled material logistics system as described above, the distance between the two lifting support rods is greater than the distance between the two legs.

[0021] For the in-plant coiled material logistics system as described above, the grid-shaped support frame is provided with diagonal reinforcing rods arranged in an X shape to enhance the overall structural strength of the support frame;

[0022] The ratio of the distance between the center position of the support rod coil shaft fixing groove and the outer shell wheel and the distance between the center position of the leg wheel and the outer shell wheel is 5 to 8:10. If the ratio is too small, the AGV leg length is too long, which affects the flexibility of the AGV. If the ratio is too large, the stability during the lifting operation is affected, that is, the lifting height is not easy to be too high, and the coil lifting height is limited.

[0023] A plurality of shelf coil shaft fixing grooves are evenly spaced on a cross bar, and the shelf coil shaft fixing grooves are symmetrically arranged on two sides of the cross bar that are perpendicular to the length direction.

[0024] In the above-mentioned coil material logistics system in a production workshop, the upper and lower sides of the cross bar are fixed with vertical bar fixing strips, the vertical bar fixing strips are arranged along the length direction of the cross bar and installed in the middle of the cross bar, the vertical bar fixing strips are provided with vertical bar fixing grooves matching the vertical bars, and the vertical bars can be inserted into the vertical bar fixing grooves to complete the fixation with the cross bar, and the cross bar and the vertical bars can be quickly assembled and disassembled conveniently;

[0025] The shelf coil shaft fixing groove on a horizontal rod is arranged on both sides of the vertical rod fixing strip.

[0026] The coil material logistics system in the production workshop as described above further includes a coil material head and tail buffer library;

[0027] The coil head and tail cache is arranged at the head or tail of the production line in the production workshop, and includes at least one group of cache brackets. A group of cache brackets includes at least two cache rods arranged horizontally, parallel to each other and spaced apart. The cache rods are provided with cache coil shaft fixing grooves for fixing the coil shaft, and the cache coil shaft fixing grooves on all cache rods in the same group of cache brackets match each other.

[0028] In the above-mentioned coil material logistics system in a production workshop, the coil material thread head and thread tail buffer warehouse further comprises a bracket fixing frame fixedly connected to at least one set of buffer brackets, and the buffer brackets are fixed to a wall or the ground through the bracket fixing frame;

[0029] A cache reinforcement rod is also provided under the cache rod, and the cache rod, the cache reinforcement rod and the bracket fixing frame form a triangular structure;

[0030] Some coils use drive-in racks as raw material intensive storage and are arranged in the raw material storage area. Some coils use drive-in racks as multi-layer line-side semi-finished storage and are arranged next to the production line. Another part of the coils use drive-in racks as product intensive storage and are arranged in the product storage area. Each warehouse in the workshop can be reasonably arranged according to the actual situation, which can make full use of the space in the workshop. Due to the horizontal layout, the multi-layer layout can be adopted through the shelf / cache bracket, which can maximize the utilization rate within the effective floor area.

[0031] A coil material logistics system in a production workshop as described above, wherein the coil material logistics system in the production workshop further includes an AGV scheduling system;

[0032] A battery, a drive motor and a controller are installed in the AGV shell, and an AGV control panel and an AGV environmental sensor are also fixed on the AGV shell. The battery supplies power to the fork frame lifting device, the drive motor, the controller, the AGV control panel and the AGV environmental sensor. The AGV environmental sensor, the AGV control panel, the drive motor and the fork frame lifting device are electrically connected to the controller respectively. The drive motor is connected to the outer shell wheel and the outrigger wheel to drive the outer shell wheel and the outrigger wheel to roll.

[0033] The AGV dispatching system is connected to the controllers of all the coil stacking AGVs, and the AGV dispatching system controls the coil stacking AGVs to transport coils in the production workshop according to the production plan of the production workshop. The control logic of the AGV is the same as that of the existing stacking AGVs, that is, its control logic is the existing mature technology.

[0034] The present invention also provides a method for operating the coil material logistics system in a production workshop as described above, comprising the following steps:

[0035] (1) The AGV dispatching system sends an instruction to the stacking AGV vehicle to take out the target coil from the raw material storage and deliver it to the target cache rack;

[0036] (2) The target coil stacking AGV drives into the target position of the raw material intensive storage warehouse so that the support rod coil shaft fixing groove on the coil stacking AGV is aligned with the coil shaft of the target coil;

[0037] (3) The lifting fork is raised so that the coil shaft of the target coil is inserted into the coil shaft fixing groove of the support rod on the coil stacking AGV vehicle and the coil shaft of the target coil is higher than the cross bar of the target coil placement position;

[0038] (4) The stacking AGV vehicle for coil materials is driven out from the target position of the raw material intensive storage warehouse and moved to the coil material head and tail buffer warehouse;

[0039] (5) After the height of the lifting fork frame of the coil stacking AGV is adjusted so that the coil shaft is higher than the target buffer bracket, the position of the coil stacking AGV is adjusted so that the coil shaft of the target coil is aligned with the buffer coil shaft fixing groove on the target buffer bracket;

[0040] (6) The lifting fork frame is lowered so that the coil shaft of the target coil is inserted into the buffer coil shaft fixing groove on the target buffer bracket;

[0041] (7) The AGV dispatching system sends an instruction to the target coil stacking AGV to take the target coil from the target buffer bracket and install it at the coil installation position of the production line. The operation process of the target coil stacking AGV is basically the same as steps (2) to (6), except for the material taking and placing positions.

[0042] (8) The AGV dispatching system sends an instruction to the stacking AGV for the target coil to take the target coil from the coil installation position of the production line and deliver it to the multi-layer line-side semi-finished warehouse. The operation process of the stacking AGV for the target coil is basically the same as steps (2) to (6), except for the material taking and placing positions.

[0043] (9) The AGV dispatching system sends an instruction to the stacking AGV vehicle for the target coil to take the target coil from the multi-layer line-side semi-finished warehouse and send it to the product intensive storage warehouse. The operation process of the stacking AGV vehicle for the target coil is basically the same as steps (2) to (6), except for the material picking and placing positions, that is, completing the circulation of the coil in the production workshop.

[0044] The operation method of the coil material logistics system in the above-mentioned production workshop is reasonably planned. The control logic of the coil material stacking AGV vehicle involved therein is all existing mature technology. The coil material stacking AGV vehicle equipped with sensors can complete the above-mentioned instructions. The coil material can complete fully mechanical and automated circulation in the workshop with high circulation efficiency, which can greatly improve the overall efficiency of the workshop.

[0045] The above technical solution is only a feasible technical solution of the present invention, and the protection scope of the present invention is not limited thereto. Those skilled in the art can reasonably adjust the specific design according to actual needs.

[0046] The above invention has the following advantages or beneficial effects:

[0047] (1) The coil material logistics system in the production workshop of the present invention has a reasonable overall design, and the use of the coil material stacking AGV vehicle and the coil material drive-in shelf to greatly improve the circulation efficiency of the coil materials in the workshop;

[0048] (2) The coil material logistics system in the production workshop of the present invention changes the current vertical storage form into a horizontal storage form by using the drive-in shelf for coil materials, eliminating the operation of turning over the coil materials in the original workshop. At the same time, the shelf adopts a drive-in design. After the coil material stacking AGV reaches a certain height, it drives into the shelf between adjacent support frames, so that the position of the coil material shaft and the coil material shaft fixing groove is basically aligned. Then, the height of the coil material is lowered so that the coil material shaft is stuck in the coil material shaft fixing groove, and the storage of the coil material is completed (the coil material retrieval operation process is similar to it). The operation is simple and can quickly complete loading and unloading. The overall structure of the shelf is simple and stable (the coil material is supported by the support frames on both sides thereof), which can realize the full mechanization and automation of the circulation of coil materials in the workshop.

[0049] (3) The coil material logistics system in the production workshop of the present invention and the coil material stacking AGV have a reasonable and relatively simple structural design. The support rod coil material shaft fixing groove on the lifting fork frame can effectively fix the coil material shaft to prevent the coil material shaft from shaking during operation. At the same time, the support rod coil material shaft fixing groove is closer to the outer shell wheel than the support leg wheel, which can greatly improve the stability of the AGV during lifting operation. It can be obtained by simply modifying the existing stacking AGV (welding the lifting fork frame). It has low cost and good applicability, can achieve the effect of one machine for multiple uses, thereby reducing the operating cost of the factory and increasing the overall operating efficiency, and has great application prospects.
