Description

Technical Field

[0001] This utility model relates to the field of woven bag salt stacking, and more particularly to a woven bag salt loading and stacking device. Background Technology

[0002] The woven bag salt loading and stacking device is a special mechanical equipment used for automated handling and stacking of woven bag packaged salt products. It is mainly used for efficient loading and unloading operations in salt plants, logistics warehouses or freight vehicles. Its core function is to neatly stack bagged salt according to a preset pattern through a robotic arm, gripping mechanism and conveying system.

[0003] Existing palletizer grippers typically have an openable gripper structure, requiring a large gripping mechanism at the end of the robotic arm, resulting in a bulky overall size. This makes them less flexible when operating in narrow carriages, making it difficult to reach into corners for gripping. Furthermore, due to the limited outer dimensions of the grippers, bagged salt cannot be precisely placed against the carriage side panels during loading, easily creating gaps between goods, affecting stacking stability and space utilization, and increasing the workload of manual adjustments.

[0004] Therefore, in view of the problems mentioned above, the existing palletizing machine grippers are usually open and close gripper structures, which occupy a lot of space, are not convenient to reach into the carriage to grab, and cannot be placed close to the sideboard for accurate placement during loading, there is an urgent need to design a new type of woven bag salt loading and palletizing device. Utility Model Content

[0005] To overcome the problems of existing palletizers, whose grippers are usually open-close grippers, occupying a lot of space, making it inconvenient to reach deep into the car body to grab, and making it impossible to place the grippers close to the sideboards for accurate loading.

[0006] The technical solution of this utility model is as follows: a woven bag salt loading and stacking device, including a fixed frame; it also includes a mounting plate, support legs, a rotating rod, a fixed rod, an electric push rod, a first hinge seat, a connecting rod, a second hinge seat, a limiting plate, a limiting groove, and a limiting rod. A mounting frame is connected to the rear side of the upper surface of the fixed frame. A housing is provided inside the mounting frame. A connecting column is slidably connected through the bottom surface of the housing. A mounting plate is provided on the bottom surface of the connecting column. Support legs are provided at the corners of the bottom surface of the mounting plate. Two symmetrical support legs are provided at the front and rear. A rotating rod is rotatably connected to the mounting plate. A fixed rod is provided on the bottom surface of the rotating rod. Electric push rods are rotatably connected to both the left and right sides of the bottom surface of the mounting plate. The telescopic end of the electric push rod is connected to a first hinge seat. One end of a connecting rod is rotatably connected to the outer surface of the first hinge seat. The other end of the connecting rod is rotatably connected to a second hinge seat. The second hinge seat is connected to the corresponding rotating rod. Limit plates are provided on both the front and rear surfaces of the mounting plate. A limit groove is opened through the front surface of the limit plate. A limit rod is installed on the outer surface of the electric push rod. The limit rod is slidably connected to the limit groove.

[0007] Preferably, by setting an electric push rod, which cooperates with the first and second hinge seats during operation, the connecting rod can drive the rotating rod to rotate 90 degrees. At the same time, the electric push rod is supported by the reverse force of the connecting rod, and it will change from an inclined state to a horizontal state. When the electric push rod rotates, it can drive the limiting rod to move upward inside the limiting groove, thereby improving the stability of the electric push rod during rotation. This allows the fixed rods on both sides to rotate synchronously, thereby realizing the gripping of woven bag salt. This solves the problem that the existing palletizer grippers are usually open and close gripper structures, which occupy a lot of space, are not convenient to reach into the carriage for gripping, and cannot be placed close to the sideboard for accurate placement during loading.

[0008] Preferably, guide rails are provided on both the front and rear sides of the inner surface of the mounting frame, and electric wheels are provided on the lower part of both the front and rear sides of the housing, with the electric wheels being compatible with the guide rails.

[0009] Preferably, a chain lift is installed on the upper right side surface of the housing, and the moving end of the chain lift is connected to the top of the connecting column.

[0010] Preferably, each of the two limiting plates has two symmetrical fixing screws on the side surface away from the mounting plate, and the limiting plates are fixed to the mounting plate by the fixing screws.

[0011] Preferably, a controller is installed on the lower part of the front surface of the housing, and a laser sensor is installed on the bottom surface of the housing.

[0012] Preferably, fixing plates are provided on the lower part of both sides of the fixed frame, and multiple equally spaced conveying rollers are rotatably connected between the fixing plates.

[0013] Preferably, multiple conveyor rollers are linked by a belt, and a drive motor is installed on the front part of the right side surface of the right fixed plate. The output end of the drive motor passes through the right fixed plate and is connected to the frontmost conveyor roller.

[0014] The beneficial effects of this utility model are:

[0015] 1. By setting up an electric push rod, whose telescopic end cooperates with the first and second hinge seats, the driving link drives the rotating rod to complete a 90-degree rotation during operation. At the same time, the reverse support of the link causes the electric push rod to gradually adjust from the initial tilted state to the horizontal state. During this process, the rotation of the electric push rod drives the limiting rod to move upward along the limiting groove. This guide structure enhances rotational stability and ensures that the fixed rods on both sides rotate synchronously, thereby achieving precise gripping of woven bag salt. This solves the problem that the existing palletizer grippers are usually open-close gripper structures, which occupy a lot of space, are not convenient to reach into the carriage for gripping, and cannot be placed close to the sideboard for precise placement during loading.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-5This utility model provides an embodiment of a woven bag salt loading and stacking device, including a fixed frame 1; it also includes a mounting plate 5, support legs 6, a rotating rod 7, a fixing rod 8, an electric push rod 9, a first hinge seat 10, a connecting rod 11, a second hinge seat 12, a limiting plate 13, a limiting groove 14, and a limiting rod 15. A mounting frame 2 is connected to the rear side of the upper surface of the fixed frame 1. A housing 3 is provided inside the mounting frame 2. A connecting column 4 is slidably connected through the bottom surface of the housing 3. A mounting plate 5 is provided on the bottom surface of the connecting column 4. Support legs 6 are provided at the corners of the bottom surface of the mounting plate 5. A rotating rod 7 is rotatably connected between two symmetrically positioned support legs 6. A fixing rod 8 is provided on the bottom surface of the rotating rod 7. Electric push rods 9 are rotatably connected to the left and right sides of the bottom surface of the mounting plate 5. The telescopic end of the electric push rod 9 is connected to the first hinge seat 10. A first hinge seat 10 is rotatably connected to the outer surface of the first hinge seat 10. One end of the connecting rod 11 is rotatably connected to a second hinge seat 12, which is connected to the corresponding rotating rod 7. Limiting plates 13 are provided on both the front and rear surfaces of the mounting plate 5. A limiting groove 14 is opened through the front surface of the limiting plate 13. A limiting rod 15 is installed on the outer surface of the electric push rod 9. The limiting rod 15 is slidably connected to the limiting groove 14. By setting the electric push rod 9, it cooperates with the first hinge seat 10 and the second hinge seat 12 during operation, which enables the connecting rod 11 to drive the rotating rod 7 to rotate 90 degrees. At the same time, the electric push rod 9 is supported by the reverse force of the connecting rod 11, and it will change from an inclined state to a horizontal state. When the electric push rod 9 rotates, it can drive the limiting rod 15 to move upward inside the limiting groove 14, thereby improving the stability of the electric push rod 9 when rotating, so that the fixed rods 8 on both sides rotate synchronously, thereby realizing the gripping of the woven bag salt.

[0024] Please see Figures 1-5 In this embodiment, guide rails 16 are provided on both the front and rear sides of the inner surface of the mounting frame 2, and electric wheels 17 are provided on the lower part of both the front and rear sides of the housing 3. The electric wheels 17 are adapted to the guide rails 16. By setting the electric wheels 17 and the guide rails 16, the housing 3 can be driven to move laterally along the mounting frame 2 during operation, thereby achieving the purpose of transporting woven bag salt from one side to the other side. A chain lifting mechanism 18 is installed on the upper part of the right side surface of the housing 3. The moving end of the chain lifting mechanism 18 is connected to the top of the connecting column 4. By setting the chain lifting mechanism 18, the connecting column 4 can drive the clamping structure below to move up and down, thereby assisting in gripping the woven bag salt. Two symmetrical fixing screws 19 are provided on the side surface of the two limiting plates 13 away from the mounting plate 5. The limiting plates 13 are fixed to the mounting plate 5 by fixing screws 19. By setting fixing screws 19, the stability of the installation of the limiting plates 13 can be improved and loosening can be avoided.

[0025] Please see Figures 1-5In this embodiment, a controller 20 is installed on the lower front surface of the housing 3, and a laser sensor 21 is installed on the bottom surface of the housing 3. The laser sensor 21, model Q50AI, has the characteristics of high precision and accuracy and can detect the position of the tension rib. Fixing plates 22 are installed on the lower left and right sides of the fixed frame 1. Multiple equally spaced conveyor rollers 23 are rotatably connected between the fixing plates 22. The fixing plates 22 are used to install the conveyor rollers 23. When the conveyor rollers 23 rotate, they can transport the woven bag salt. The multiple conveyor rollers 23 are linked by a belt. A drive motor 24 is installed on the front right side of the right fixing plate 22. The output end of the drive motor 24 passes through the right fixing plate 22 and is connected to the frontmost conveyor roller 23. When the drive motor 24 is set, its output end can drive one of the conveyor rollers 23 connected to it to rotate during operation, thereby cooperating with the belt to drive the other conveyor rollers 23 to rotate.

[0026] During operation, the electric wheel 17 and guide rail 16 drive the housing 3 to move laterally along the mounting frame 2, thereby transporting the woven bag salt from one side to the other. The chain lift 18 allows the connecting column 4 to move the clamping structure below up and down, assisting in gripping the woven bag salt. The fixing screw 19 improves the stability of the limit plate 13 installation and prevents it from loosening. The laser sensor 21, model Q50AI, with high precision and accuracy, can detect the position of the tensioner. The fixing plate 22 is used to install the conveyor roller 23, which transports the woven bag salt when rotating. The drive motor 24 drives one of the connected conveyor rollers 23 to rotate during operation, which in turn drives the other conveyor rollers 23 to rotate in conjunction with the belt.

[0027] Through the above steps, by setting up an electric push rod 9, whose telescopic end cooperates with the first hinge seat 10 and the second hinge seat 12, the connecting rod 11 drives the rotating rod 7 to complete a 90-degree rotation during operation. At the same time, the reverse support of the connecting rod 11 causes the electric push rod 9 to gradually adjust from the initial tilted state to the horizontal state. During this process, the rotation of the electric push rod 9 drives the limiting rod 15 to move upward along the limiting groove 14. This guide structure enhances the rotational stability and ensures that the fixed rods 8 on both sides rotate synchronously, thereby achieving precise gripping of woven bag salt. This solves the problem that the existing palletizer grippers are usually open-close gripper structures, which occupy a lot of space, are not convenient to penetrate into the carriage for gripping, and cannot be placed close to the side panel for precise placement during loading.
