Description

Technical Field

[0002] During production operations in the tobacco-making workshops of cigarette factories, large quantities of cut tobacco need to be packaged and shipped out of town. As a critical link in product distribution, the efficiency and quality of this shipping process directly impact the stability of the company's supply chain. Currently, the industry generally uses automated equipment to package and seal tobacco into cartons. Subsequent manual labor is required to individually transport the heavy tobacco cartons and place them on pallets. Forklifts then transfer the stacked tobacco pallets to logistics trucks. The traditional manual palletizing model has significant defects: First, manual handling cannot ensure the regularity of carton stacking, resulting in inefficient utilization of pallet space, directly affecting the number of single loads, and increasing logistics and transportation costs; second, a single tobacco carton is heavy, and workers need to repeat high-load actions such as bending, carrying, and stacking for a long time, which can easily cause occupational diseases such as lumbar muscle strain and joint injury. In addition, there are safety hazards such as cartons slipping and hitting during frequent handling, which seriously threatens the health of operators; third, the efficiency of manual palletizing is limited by the physical strength and proficiency of workers, and it is difficult to meet the timeliness requirements of large-scale tobacco shipments from cigarette factories. It is easy to cause tobacco backlogs during the peak production season, hindering the smooth progress of the production process.

[0036] like Figures 1 to 4 As shown, this embodiment provides an automatic palletizing and transferring device for cartons, including a transport mechanism 1, a transport mechanism 2 and a palletizing mechanism 3. The transport mechanism 2 has a loading position for clamping a carton 100 and a discharge position for releasing the carton 100, and the loading position and the discharge position are relatively spaced apart. The transport mechanism 2 includes a transport drive assembly 21 and a clamping assembly 22. The clamping assembly 22 is used to clamp the carton 100. The output end of the transport drive assembly 21 is transmission-connected to the clamping assembly 22 for driving the clamping assembly 22 to transfer between the loading position and the discharge position. The transport mechanism 1 is used to transport the carton 100 to the loading position; the palletizing mechanism 3 ... The stacking mechanism 3 includes a lifting drive component 31, a rotating drive component 32 and at least two pallets 33. The output end of the rotating drive component 32 is connected to the pallet 33 in a transmission manner. The pallet 33 has multiple stacking areas that are centrally symmetrical along its central axis. At least one stacking area is located at the unloading position. The rotating drive component 32 is used to drive the pallet 33 to rotate around its central axis so that the multiple stacking areas are switched to the unloading position in sequence, and the pallet 33 can be stacked on the carton 100. The output end of the lifting drive component 31 is connected to the rotating drive component 32 in a transmission manner, and is used to drive the rotating drive component 32 to drive the pallet 33 to move in the vertical direction.

[0037] The carton 100 is transported to the loading position by the transport mechanism 1, the clamping component 22 clamps the carton 100, the transport drive component 21 drives the clamping component 22 to transfer the carton 100 to the unloading position, and the clamping component 22 releases the carton 100, so that the carton 100 is stacked in the palletizing area of the pallet 33 at the unloading position; then the rotary drive component 32 drives the pallet 33 to rotate, so that the next palletizing area rotates to the unloading position, and at the same time the transport drive component 21 drives the clamping component 22 to return to the loading position, and repeats the above steps for transport and palletizing until each palletizing area of the pallet 33 is loaded with cartons 100; then another pallet 33 is stacked on the carton 100 by manual or automated means, and transport and palletizing are continued, and the above steps are repeated until the preset number of palletizing layers is reached, and the multi-layer stacked cartons 100 can be transferred to the transport vehicle for loading.

[0038] The above-mentioned automatic carton stacking and transfer device drives the pallet 33 to rotate around its central axis through the rotating drive component 32, so that multiple stacking areas are switched to the unloading position in turn, ensuring that the position of the cartons 100 stacked each time on the pallet 33 is accurate, and the multiple layers of pallets 33 are stacked, and the positions of the cartons 100 on the multiple layers of pallets 33 correspond, which improves the regularity of the stacking of the cartons 100, maximizes the utilization of the space of the pallet 33, significantly increases the number of single loadings, and is conducive to reducing logistics and transportation costs; secondly, mechanical automation is used to replace manual repetitive and high-intensity operations, and the full process automation of the tobacco cartons 100 from packaging to palletizing on the pallet 33 is realized, which improves the degree of automation of the transportation and stacking of the cartons 100, reduces the labor intensity of workers, and eliminates personal safety hazards; in addition, with the help of efficient automatic control and fast transportation and stacking mechanism, the stacking efficiency can be greatly improved, meeting the timeliness requirements of large-scale tobacco outbound shipments from cigarette factories, ensuring the smooth operation of the production process, and promoting the upgrading of the cigarette production logistics link to the direction of intelligence and efficiency.

[0039] Among them, the stacking mechanism 3 and the transport mechanism 1 are arranged opposite to each other along the transport direction of the transport mechanism 1, and the stacking mechanism 3 is arranged at intervals downstream of the transport mechanism 1, the loading position is located at the end of the transport mechanism 1 along the transport direction, and the unloading position is located at one end of the stacking mechanism 3 close to the transport mechanism 1.

[0040] like Figure 1 and Figure 2 As shown, in some optional embodiments, the conveying mechanism 2 also includes a first in-place detection member 23, which is arranged on the clamping assembly 22 and is used to detect the carton 100 at the loading position, and the first in-place detection member 23 is electrically connected to the conveying drive assembly 21 and the clamping assembly 22. When the transport mechanism 1 transports the carton 100 to the loading position, the first in-place detection member 23 detects the carton 100 and transmits a signal to the transport mechanism 1, the conveying drive assembly 21 and the clamping assembly 22. The transport mechanism 1 stops conveying, and the clamping assembly 22 clamps the carton 100. The conveying drive assembly 21 drives the clamping assembly 22 to move the carton 100 to the unloading position. At this time, the carton 100 is in one of the stacking areas of the pallet 33, and the clamping assembly 22 releases the carton 100 to complete one stacking; then the conveying drive assembly 21 drives the clamping assembly 22 to reset to the loading position, and the transport mechanism 1 transports the carton 100 again, and repeats the above steps for multiple stacking.

[0041] Among them, the clamping component 22 is initially in the loading position. When the carton 100 moves to the loading position, the upper edge of the carton 100 is directly below the first in-place detection component 23, so that after the transport mechanism 1 moves the carton 100 to the designated position, the clamping component 22 can automatically clamp and transfer the carton 100.

[0042] Optionally, the first in-position detection member 23 includes but is not limited to an infrared laser emitter, a beam-type photoelectric sensor or a proximity switch, which is not limited here.

[0043] Optionally, the transport drive assembly 21 includes but is not limited to a motor, a cylinder or a hydraulic cylinder, which is not limited here.

[0044] In some optional embodiments, the transport mechanism 2 further includes a bracket 24, which is mounted on the transport mechanism 1, and the transport drive assembly 21 is arranged on the bracket 24. The clamping assembly 22 includes a clamping drive member 221, a mounting seat 222, a lifting seat 223, at least two moving members 224 and at least two transmission members 225. The clamping drive member 221 and the mounting seat 222 are both arranged at the output end of the transport drive assembly 21. The at least two moving members 224 are arranged opposite to each other, and one end of each moving member 224 is slidably connected to the mounting seat 222, and the other end is provided with a clamping member 226, which is used to clamp the carton 100. The lifting seat 223 is arranged at the output end of the clamping drive member 221. At least one transmission member 225 is provided between the lifting seat 223 and each moving member 224. One end of the transmission member 225 is pin-connected to the moving member 224, and the other end is pin-connected to the lifting seat 223. The clamping drive member 221 is used to drive the lifting seat 223 to move in the vertical direction. When the clamping drive member 221 drives the lifting seat 223 to rise, the lifting seat 223 drives the moving members 224 to approach each other through the transmission member 225. When the clamping member 226 drives the lifting seat 223 to descend, the lifting seat 223 drives the moving members 224 to move away from each other through the transmission member 225.

[0045] The bracket 24 provides a stable support for the transport drive assembly 21 and the clamping assembly 22, which can prevent the carton 100 from shaking and falling during transportation, and reduce wear and tear on the equipment. Through the linkage of the "clamping drive member 221-lifting seat 223-transmission member 225-moving member 224", the opening and closing of the moving member 224 can be accurately controlled to adapt to cartons 100 of different sizes, maintain uniform force, and prevent deformation and damage to the carton 100. The transport drive assembly 21 can drive the clamping assembly 22 to move along the direction of the loading position and the unloading position, thereby transferring the carton 100 from the loading position to the unloading position. The transport drive assembly 21 and the clamping assembly 22 work together to quickly complete the grabbing, transporting and placement of the carton 100, greatly improving work efficiency.

[0046] In some optional embodiments, a first guide groove 241 extending along the output direction of the transport drive assembly 21 is provided on the bracket 24, and the transport mechanism 2 also includes a sliding seat 25, which slides with the first guide groove 241, and the clamping drive 221 and the mounting seat 222 are both connected to the sliding seat 25. The first guide groove 241 cooperates with the sliding seat 25 to provide precise guidance for the movement of the clamping assembly 22, ensuring that the clamping assembly 22 moves smoothly along the output direction of the transport drive assembly 21, reducing shaking and deviation, and ensuring the stability and safety of the carton 100 during the transport process. When the sliding seat 25 is located in the first guide groove 241 close to one end of the transport mechanism 1, the clamping assembly 22 is located in the loading position; when the sliding seat 25 is located in the first guide groove 241 close to one end of the stacking mechanism 3, the clamping assembly 22 is located in the unloading position. The first guide groove 241 precisely limits the moving stroke of the clamping assembly 22, so that the clamping assembly 22 can accurately reach the loading and unloading positions, preventing the carton 100 from failing to be grasped or misplaced due to position deviation, and effectively improving the accuracy and success rate of handling and stacking.

[0047] Optionally, the clamping drive member 221 includes but is not limited to a motor, a cylinder or a hydraulic cylinder, which is not limited here.

[0048] In some optional embodiments, a second guide groove extending along the sliding direction of the moving member 224 is provided on the mounting seat 222, and a T-shaped sliding block 2241 is provided on the moving member 224 that slides with the second guide groove. The sliding cooperation between the second guide groove and the T-shaped sliding block 2241 provides precise guiding for the movement of the moving member 224, which is beneficial to ensure that the moving member 224 slides smoothly and stably in the direction of moving away from or approaching each other under the action of the transmission member 225, so as to ensure that the clamping member 226 clamps or releases the carton 100.

[0049] In some optional embodiments, the clamping drive member 221 is arranged at the upper end of the sliding seat 25, and the mounting seat 222 is arranged at the lower end of the sliding seat 25. The output end of the clamping drive member 221 is passed through the sliding seat 25 and slides with the sliding seat 25 in the vertical direction. The sliding cooperation between the sliding seat 25 and the output end of the clamping drive member 221 provides a guiding and supporting function for the output end of the clamping drive member 221, which is beneficial to improving the load capacity of the clamping assembly 22.

[0050] like Figure 1 and Figure 3As shown, in some optional embodiments, the stacking mechanism 3 further includes a second in-place detection member 34, which is arranged on one side of the unloading position for detecting the carton 100 at the unloading position, and the second in-place detection member 34 is electrically connected to the lifting drive assembly 31 and the rotary drive assembly 32. When the clamping assembly 22 stacks the carton 100 in the stacking area at the unloading position, the second in-place detection member 34 detects the carton 100 and sends a signal to the rotary drive assembly 32. The rotary drive assembly 32 drives the tray 33 to rotate so that the next stacking area rotates to the unloading position to facilitate the stacking of the next carton 100, until each stacking area of the tray 33 is loaded with a carton 100. After the lifting drive assembly 31 receives the signal, it drives the tray 33 to drive the carton 100 to descend. The descending distance is the sum of the height of the carton 100 and the height of the tray 33, so that after another tray 33 is stacked on the carton 100, the height of the stacking area remains unchanged, thereby performing the next group of stacking.

[0051] Among them, when the carton 100 is stacked in the stacking area at the unloading position, the side edge of the carton 100 is directly in front of the second in-place detection component 34, so that when the carton 100 is transferred to the stacking area of the pallet 33, the rotating drive assembly 32 can automatically drive the pallet 33 to rotate, so that the next stacking area rotates to the unloading position.

[0052] Optionally, the second in-position detection member 34 includes but is not limited to an infrared laser emitter, a beam-type photoelectric sensor or a proximity switch, which is not limited here.

[0053] In some optional embodiments, the stacking mechanism 3 further includes a base 35 and a detection frame 36, the lifting drive assembly 31 is arranged on the base 35, and the detection frame 36 includes a vertical portion 361 and a horizontal portion 362 connected at an angle from top to bottom, the horizontal portion 362 is connected to the base 35, and the vertical portion 361 is used to install the second in-place detection member 34. The lifting drive assembly 31 is supported by the base 35, and the second in-place detection member 34 is connected to the base 35 through the detection frame 36, so that the various components of the stacking mechanism 3 are compactly integrated, effectively reducing the space occupied by the stacking mechanism 3, improving the space utilization efficiency of the equipment, and facilitating installation and use in the limited space of the tobacco factory's silk workshop. Optionally, the lifting drive assembly 31 includes but is not limited to using a motor, a cylinder, or a hydraulic cylinder, which is not limited here.

[0054] In some optional embodiments, the stacking mechanism 3 further includes a bearing member 37, which is arranged at the output end of the rotary drive assembly 32 for carrying the pallet 33, and a fork groove 371 is provided at the upper end of the bearing member 37 for accommodating the fork arm of a forklift. When the carton 100 reaches the preset number of stacking layers, the fork arm of the forklift is inserted into the fork groove 371, and the multi-layer stacked cartons 100 can be transported. In this embodiment, the preset number of stacking layers is two layers, which is adapted to the height of the truck compartment. In other embodiments, the preset number of stacking layers includes but is not limited to three or four layers, which is not limited here. Optionally, the rotary drive assembly 32 includes but is not limited to the use of a hydraulic rotary disc or a motor, which is not limited here.

[0055] like Figure 4 As shown, in some optional embodiments, the palletizing mechanism 3 further includes a mounting assembly 38, which includes a rotating support 381, a first mounting plate 382, a second mounting plate 383, and a plurality of support columns 384.

The second mounting plate 383 is provided with a rotating support 381. The output shaft of the rotating drive assembly 32 is passed through the rotating support 381 and is rotatably connected to the rotating support 381, which can provide guidance and support for the output shaft of the rotating drive assembly 32, thereby improving the load capacity of the rotating drive assembly 32, thereby meeting the palletizing requirements of multiple heavy cartons 100. Optionally, the rotating support 381 includes, but is not limited to, a bearing or a bushing, which is not limited herein.

[0060] In some optional embodiments, the pallet 33 is a square pallet 33, each of which includes four centrally symmetrically arranged stacking areas. The square pallet 33 is regularly shaped and centrally symmetrical, resulting in a regular layout of the four centrally symmetrical stacking areas. This facilitates precise positioning of the transport mechanism 2, ensures that the 100 cartons are neatly stacked, maximizes the utilization of the pallet 33's surface area, and improves the loading volume ratio. Furthermore, the standardized stacking areas facilitate the development of unified operating procedures and control programs, reducing the difficulty of equipment programming and debugging. Furthermore, the symmetrical structure facilitates the transport mechanism 2 to utilize repetitive action logic to complete stacking, thereby improving operational efficiency and facilitating subsequent manual or mechanical handling and stacking of the pallets 33.

[0061] In some optional embodiments, the automatic palletizing and transporting device for cartons further includes a controller 4, which is electrically connected to the first in-place detection member 23, the second in-place detection member 34, the clamping drive member 221, the transport drive assembly 21, and the rotation drive assembly 32. The controller 4 can receive signal feedback from the first and second in-place detection members 34 in real time, accurately judge the position of the carton 100 and the state of the pallet 33, ensure that the clamping drive member 221, the transport drive assembly 21, and the rotation drive assembly 32 act at the appropriate time, avoid misoperation, and achieve precise control of the entire process of the carton 100 from grabbing, transporting to palletizing. At the same time, through preset programs and algorithms, the controller 4 can coordinate the various components to work together, optimize the action sequence, reduce the idle travel time, and greatly improve the efficiency of palletizing and transporting.
