Description

Technical Field

[0001] This utility model relates to a palletizing device, and more particularly to a palletizing device for bagged materials. Background Technology

[0002] In industrial production, palletized stacking is commonly used for the storage and transportation of bagged materials. In the traditional process, workers need to manually move the materials bag by bag onto the pallet, and achieve stable stacking by repeatedly adjusting the placement angle and the staggering between layers. This manual operation is not only labor-intensive and inefficient, but also highly dependent on the experience of the workers, and the stability and neatness of the stacking vary significantly among different operators.

[0003] While some existing mechanical palletizing devices can achieve automatic stacking, they mostly employ a unidirectional continuous stacking method, resulting in a lack of interlocking structures between layers. This linear stacking in one direction makes the stack prone to overall displacement or even collapse during transportation vibrations or storage compression. Furthermore, fixed guide structures are difficult to adapt to the placement requirements of materials of different sizes, often requiring manual intervention and adjustments, which increases operational complexity. These structural defects make it difficult to balance palletizing efficiency and stability, becoming a bottleneck problem restricting material flow efficiency. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a bagged material palletizing device.

[0005] A bagged material palletizing device includes a base plate, a support frame, a conveyor, a guide seat 1, a worktable, a fixed base, a transmission component 3, a slide seat 2, a guide seat 2, a synchronous belt assembly, a drive motor, a pallet, a U-shaped frame, a vision module, and the conveyor. The support frame is fixedly mounted on the top front side of the base plate. The conveyor is mounted on the upper part of the support frame, transporting the bagged materials to be stacked. Guide seats 1 are symmetrically arranged on the left and right sides of the upper part of the support frame, and the worktable is connected between the guide seats 1. The bagged materials transported by the conveyor fall onto the top right side of the worktable. A fixed base is vertically mounted on the top rear side of the base plate. The transmission component 3 is installed inside the fixed base. The transmission component 3 consists of a motor and a vertically arranged lead screw. A slide seat 2 is slidably mounted on the front of the fixed base. The slide seat 2 is screwed to the lead screw of the transmission component 3, and the transmission component 3 drives the slide seat 2 to move on the fixed base. The slide moves up and down. A connecting frame is fixed at the front of the slide two. A guide seat two is horizontally located at the lower part of the connecting frame. A synchronous belt assembly is installed at the front of the guide seat two. The synchronous belt assembly consists of two synchronous pulleys and a synchronous belt wrapped around the two synchronous pulleys. A drive motor is installed on one side of the guide seat. The output shaft of the drive motor is fixedly connected to one of the synchronous pulleys. Two trays are slidably installed on the guide seat. The two trays are connected to the upper and lower parts of the synchronous belt, respectively. When the synchronous belt assembly rotates, the synchronous belt drives the two trays to slide in opposite directions or back to back. A U-shaped frame is installed on the connecting frame. A vision module is installed on the upper part of the connecting frame. The vision module faces the top of the workbench. A conveyor is located on the top of the base plate near the fixed seat. The conveyor is used to convey pallets of stacked bagged materials. When the pallets move with the conveyor, they will pass under the two trays.

[0006] To further explain, the placement mechanism includes a rack, a slide table, a sliding frame, a first transmission component, a second transmission component, a first slide block, a first cylinder, a telescopic arm, a drive motor, and a pusher plate. Each guide seat has a sliding slide table, and the tops of the slide tables are connected to the sliding frame. A rack is mounted on the front guide seat, and a first transmission component is mounted on the front slide table. The first transmission component consists of a motor and a gear. The gear in the first transmission component meshes with the rack, driving the front slide table to move back and forth laterally, which in turn drives the sliding frame to move back and forth laterally. The upper part of the sliding frame is equipped with... There is a second transmission component, on which a first slide is mounted. The second transmission component drives the first slide to move left and right. A telescopic arm is slidably mounted on the lower part of the first slide. A first cylinder is mounted on the first slide. The movable rod of the first cylinder is connected to the front end of the telescopic arm. A pusher plate is rotatably mounted at the rear end of the telescopic arm. The pusher plate is generally L-shaped. A drive motor is mounted on the telescopic arm. The output shaft of the drive motor is connected to the rotation axis of the pusher plate. The drive motor drives the pusher plate to rotate. When the movable rod of the first cylinder extends or retracts, it drives the telescopic arm to move back and forth, thereby driving the pusher plate to move back and forth.

[0007] To further explain, the drive motor drives the pusher plate to rotate 90 degrees back and forth.

[0008] To further explain, it also includes guide plates and position sensors. Guide plates are provided on both guide seats, and the two guide plates are arranged symmetrically front and back. The rear end of the guide plate contacts the front end of the C-shaped frame. Position sensors are provided on both guide plates. During the process of the transmission component three driving the slide to move upward, the front top of the two support plates on the guide seat two will contact the position sensors on the guide plates. At this time, the upper surface of the support plate is at the same height as the top surface of the worktable.

[0009] Further explanation: It also includes a mounting base, cylinder two, a top plate and a conveying component. The mounting base is provided on one end of the bottom plate near the conveying component. Multiple cylinder two are vertically arranged inside the mounting base. The cylinder two are arranged in a rectangular distribution in the fixed base. The top plate is provided between the upper ends of the movable rods of the cylinder two. The conveying component is provided on the top plate.

[0010] To further explain, the air inlets of cylinder two are all connected to the air outlet of the same air source device, and each cylinder two is equipped with a flow regulating valve on its air inlet pipe. The valve opening of each flow regulating valve is kept consistent after being preset and calibrated to ensure that the compressed gas flow rate entering each cylinder two is the same, and multiple cylinder twos operate synchronously.

[0011] The beneficial effects are as follows: 1. By setting up a placement mechanism and a stacking mechanism in the bagged material unloading area, the material can be stacked on the pallet in a cross-shaped and layered manner. Compared with the existing stacking method that relies solely on manual placement or stacking in a single direction, this not only saves the tedious operation of repeatedly adjusting the position of the material manually, but also improves the overall structural stability of the stack and avoids the phenomenon of tipping over or scattering of the material during transportation or storage.

[0012] 2. The coordination between the transmission components and various drive parts in this device forms a continuous operation process from material feeding to pallet unloading. The transmission components stably transport the material to the workbench, and the pallet is accurately delivered. The smooth connection between each link reduces the waiting time for material and pallet transfer and improves the overall efficiency of palletizing operation. Attached Figure Description

Detailed Implementation

[0019] The preferred technical solution of this utility model will be described in detail below with reference to the accompanying drawings.

[0020] Example 1

[0021] A bagged material palletizing device, such as Figure 1-5 As shown, the device includes a base plate 1, a support frame 2, a transmission component 3, a guide seat 4, a worktable 411, a fixed base 5, a transmission component 51, a slide 52, a guide seat 53, a synchronous belt assembly 54, a drive motor 55, a pallet 56, a U-shaped frame 57, a vision module 58, and a transmission component 6. The support frame 2 is fixedly mounted on the front top of the base plate 1, providing support for the upper components and ensuring stable installation. The transmission component 3 is located on the upper part of the support frame 2, transporting the bagged materials 200 that need to be stacked. One end of the transmission component 3 connects to the feeding area, introducing the bagged materials 200 into the device. During transport, it conveys the bagged materials 200 towards the worktable 411, achieving material transfer. Guide seats 4 are symmetrically located on the left and right sides of the upper part of the support frame 2, providing the installation foundation for the worktable 411. The guide seats 4 contain... The workbench 411 is connected to the transmission component 3. The bagged material 200 conveyed in the transmission component 3 will fall into the top right side of the workbench 411. Due to the fixation of the guide seat 4, the position of the workbench 411 is stable, ensuring accurate material delivery. The bottom plate 1 has a fixed seat 5 vertically installed on the rear side of the top. The fixed seat 5 provides installation support for the transmission component 3 51 and the slide 2 52. The transmission component 3 51 is installed in the fixed seat 5. The transmission component 3 51 consists of a motor and a vertically set lead screw. The motor can drive the lead screw to rotate. The slide 2 52 is slidably installed at the front of the fixed seat 5. The slide 2 52 is screwed to the lead screw of the transmission component 3 51. The motor of the transmission component 3 51 is controlled to rotate forward and reverse, driving the lead screw to rotate, thereby driving the slide 2 52 to move up and down in the fixed seat 5. The transmission component 3 51 drives the slide 2 52 to move up and down in the fixed seat 5 to adjust the height of the slide 2 52.

[0022] A connecting frame 521 is fixedly provided at the front of the slide 2 52. The connecting frame 521 moves synchronously with the slide 2 52. A guide seat 2 53 is provided horizontally on the left and right sides of the lower part of the connecting frame 521. The guide seat 2 53 provides installation and sliding guidance for the synchronous belt assembly 54 and the support plate 56. The synchronous belt assembly 54 is installed at the front of the guide seat 2 53. The synchronous belt assembly 54 consists of two synchronous pulleys and a synchronous belt wrapped around the two synchronous pulleys. The synchronous belt can flow with the rotation of the synchronous pulleys. A drive motor 55 is provided on the side of the guide seat 1 4. The output shaft of the drive motor 55 is fixedly connected to one of the synchronous pulleys. When the drive motor 55 is started, its output shaft drives the synchronous pulley to rotate, thereby making the synchronous belt assembly 54 run. The guide seat is slidably provided with two support plates 56. The two support plates 56 are respectively connected to the upper and lower parts of the synchronous belt. When the synchronous belt assembly 54 flows, the synchronous belt drives the two support plates 56 to slide in opposite directions or back directions. Sliding in opposite directions can reduce the gap to receive materials, and sliding back directions can increase the gap to release materials.

[0023] A U-shaped frame 57 is installed on the connecting frame 521. The U-shaped frame 57 can limit and guide the material entering the pallet 56. Its coverage area is consistent with the top area of ​​the pallet 100. A placement mechanism is provided on the guide seat 4. After the material falling into the workbench 411 is adjusted to a certain position by the placement mechanism, it is pushed onto the pallet 56. A conveyor 6 is provided on the top of the base plate 1 near the fixed seat 5. The conveyor 6 is used to convey the pallet 100 of stacked bagged material 200. When the conveyor 6 is turned on, the pallet 100 will pass under the two pallets 56 as it moves with the conveyor 6, so as to receive the material placed on the pallet 56.

[0024] Among them, such as Figure 1-3As shown, the placement mechanism includes a rack 41, a slide 42, a sliding frame 421, a first transmission component 422, a second transmission component 43, a first slide base 44, a first cylinder 45, a telescopic arm 46, a drive motor 47, and a pusher plate 48. Each guide seat 42 is slidably equipped with a slide 42, which can slide on the guide seat 4. A sliding frame 421 is connected between the tops of the slides 42. The movement of the slides 42 causes the sliding frame 421 to move synchronously. A rack 41 is provided on the front guide seat 4, and a transmission component is provided on the front slide 42. Part 1 422 consists of a motor and a gear. The gear in Part 1 422 meshes with a rack 41. When the motor in Part 1 422 is started, the gear rotates and moves along the rack 41. This drives the front slide 42 to move back and forth horizontally, which in turn drives the sliding frame 421 to move back and forth horizontally, thus adjusting the position of the sliding frame 421. Part 2 43 is mounted on the upper part of the sliding frame 421. Part 2 43 can drive the slide base 44 to move. The slide base is mounted on Part 2 43. A transmission component 43 drives the slide block 44 to move left and right, allowing the slide block 44 to adjust its position on the sliding frame 421. A telescopic arm 46 is slidably mounted on the lower part of the slide block 44. A cylinder 45 is mounted on the slide block 44, and the movable rod of the cylinder 45 is connected to the front end of the telescopic arm 46. Controlling the extension and retraction of the movable rod of the cylinder 45 drives the telescopic arm 46 to move back and forth. A pusher plate 48 is rotatably mounted at the rear end of the telescopic arm 46. The pusher plate 48 can rotate within the telescopic arm 46. The rear end rotates, and the pusher plate 48 is in an "L" shape, which facilitates pushing materials from different directions. The telescopic arm 46 is equipped with a drive motor 47. The output shaft of the drive motor 47 is connected to the rotation axis of the pusher plate 48. When the drive motor 47 is started, its output shaft drives the pusher plate 48 to rotate. When the pusher plate 48 is rotated by the drive motor 47, the movable rod of the cylinder 45 extends and retracts, which drives the telescopic arm 46 to move back and forth, thereby driving the pusher plate 48 to move back and forth, realizing the rotation and back and forth movement of the pusher plate 48 to adjust the material.

[0025] Among them, such as Figure 1 , Figure 2 and Figure 4 As shown, a vision module 58 is installed on the upper part of the connecting frame 521. The vision module 58 faces the top of the worktable 411 and is used to observe the state of the bagged material 200 before it enters the two pallets 56. By capturing information such as the position and angle of the material, the module feeds this information back to the control system in real time, providing a precise basis for the action of the pusher plate 48, so that the pusher plate 48 can accurately adjust its own position and angle, and accurately push and adjust the angle of the material.

[0026] like Figure 1 and Figure 3As shown, it also includes guide plates 8 and position sensors 81. Guide plates 8 are provided on both guide seats 4. The guide plates 8 provide guidance for the material to move from the worktable 411 to the tray 56, preventing the material from deviating. The two guide plates 8 are arranged symmetrically front and back, and the rear end of the guide plate 8 contacts the front end of the U-shaped frame 57, so that the material can smoothly transition from the guide plate 8 to the tray 56 inside the U-shaped frame 57. Position sensors 81 are provided on the guide plates 8. The position sensors 81 can detect the position of the tray 56. When the transmission component 3 51 drives the slide to move upward, when the front top of the two trays 56 on the guide seat 2 53 contacts the position sensor on the guide plate 8, the position sensor 81 sends a signal to control the transmission component 3 51 to stop. At this time, the upper surface of the tray 56 is at the same height as the top side of the worktable 411, ensuring that the material can be smoothly pushed from the worktable 411 to the tray 56.

[0027] When the bagged materials 200 are placed, the drive motor 47 drives the pusher plate 48 to rotate 90 degrees back and forth, ensuring that the pusher plate 48 can be precisely adjusted in angle. For details on stacking, please refer to [link / reference needed]. Figure 5 The single-layer bagged material 200 is required to be stacked in a cross-placement manner, that is, seven bags of material 200 are placed in a single layer with two horizontal and three vertical rows. The pusher plate 48 of the stacking mechanism is used to adjust the angle and position of the material transferred to the worktable 411 and push it onto the tray 56 in the area of ​​the U-shaped frame 57. When it is necessary to place the material horizontally, the drive motor 47 is not activated, the pusher plate 48 maintains its initial angle, and the overall position of the pusher plate 48 is adjusted by the transmission component 1 422 and the transmission component 2 43 so that it contacts the side of the bagged material 422. When cylinder 45 extends its movable rod, telescopic arm 46 moves pusher plate 48 forward, directly pushing the material along workbench 411 to the horizontal position of pallet 56. When the material needs to be placed vertically, drive motor 47 is started, rotating pusher plate 48 90 degrees so that the other side of pusher plate 48 faces the material. Then, cylinder 45 extends its movable rod, pusher plate 48 pushes the material to rotate 90 degrees, and continues to push it to the vertical position of pallet 56. The angle of the material is adjusted by the rotation of L-shaped pusher plate 48. With the help of other transmission components, the pushing action pushes the material into pallet 56. During the placement process, the operator adjusts the front and rear position of sliding frame 421 by controlling transmission component 422 and adjusts the left and right position of sliding block 44 by controlling transmission component 43, thereby moving pusher plate 48 to the corresponding position of the material. Seven materials are adjusted and pushed in sequence to complete the two horizontal and three vertical placement of one layer.

[0028] The conveyor 6 connects to the pallet 100 placement area and the unloading area at both ends. When stacking is required, the operator controls the conveyor 6 to accurately stop the empty pallet 100 placed on it at a suitable position below the two pallets 56. After a layer of material is placed on the pallets 56, the operator starts the drive motor 55, and the synchronous belt group 54 drives the two pallets 56 to slide back to back, so that the material is directly above the pallet 100. Then, the operator starts the motor of the third drive component 51, which drives the slide 2 52 to descend, and the pallets 56 and the material move down to contact the pallet 100. Then, the operator controls the drive motor 55 to reverse, and the two pallets 56 move back to their original positions. The pallet 56 slides away from the material. Under the limiting action of the U-shaped frame 57, the bagged material 200 does not move away from the material release area with the pallet. After the pallet 56 falls onto the pallet 100, the motor of the transmission component 3 51 is reversed, the slide 2 52 rises and resets, and the synchronous belt group 54 is controlled to rotate in the opposite direction, so that the two pallets 56 are reset, completing the operation of putting one layer of material onto the pallet 100. Then, according to the same logic, the angle of the pusher plate 48 is adjusted. The bagged materials of adjacent layers are arranged in two horizontal and three vertical rows in a single layer. The materials between layers need to be placed crosswise until multiple layers are stacked. The conveyor 6 moves the pallet towards the material release area.

[0029] In addition, as shown in the figure, it also includes a mounting base 7, cylinder 71, a top plate 72, and a conveying component 73. The mounting base 7 is located on the bottom plate 1 near the conveying component 6, providing a stable mounting foundation for cylinder 71. Multiple cylinders 71 are vertically mounted inside the mounting base 7, arranged in a rectangular pattern within the fixed base 5 to ensure balanced force distribution on the top plate 72. The air inlets of all cylinders 71 are connected to the outlet of the same air source device, which provides compressed gas to the cylinders 71. Each cylinder 71's air inlet pipe is equipped with a flow regulating valve, which controls the flow of gas entering the cylinder. The gas flow rate of cylinder 2 71 and the valve opening of each flow regulating valve are kept consistent after preset calibration. This ensures that when the gas source device supplies gas, compressed gas can enter each cylinder 2 71 simultaneously and in equal amounts. The gas pushes the piston in cylinder 2 71 to move synchronously, which in turn drives the movable rod to extend and retract synchronously. This ensures that the compressed gas flow rate entering each cylinder 2 71 is the same, thus enabling multiple cylinders 2 71 to operate synchronously. This synchronicity ensures that the top plate 72 will not tilt to one side during the lifting and lowering process, and will always remain in a horizontal state, providing stable support and a foundation for the pallet 100. The top plate 72 is located between the upper ends of the movable rods of cylinder 2 71. When cylinder 2 71 is started, its movable rod extends and retracts, causing the top plate 72 to move up and down. The top plate 72 is equipped with a conveyor 73, which can move the pallet 100 on it. When the conveyor 6 transports the pallet 100 to the corresponding position above the top plate 72, the control cylinder 71 is activated, the movable rod extends upward, and the top plate 72 moves upward. The top plate 72 gradually approaches and contacts the bottom of the pallet 100. As the movable rod continues to extend, the top plate 72 lifts the pallet 100 off the conveyor 6, allowing the pallet 100 to detach from the conveyor 6 and be fully supported by the top plate 72. At this time, the conveyor 73 is activated, moving and adjusting the pallet 100 from the conveyor 6 to a centered position, ensuring the accurate positioning of the pallet 100 for subsequent stacking. The purpose of the vertical movement of the top plate 72 is that after stacking is completed, the movable rod of the control cylinder 71 retracts, causing the top plate 72 and the pallet 100 with stacked materials to move downward, lowering the pallet 100 to a suitable height. This facilitates the insertion of the forks of the forklift equipment into the bottom of the pallet 100 for forklift handling, eliminating the need for excessive height adjustments by the forklift equipment and improving forklift efficiency.
