Lifting and transporting device for cigarette package stacking

Abstract

A lifting and transporting device for stacking cigarette packs is disclosed. The device has grooves machined on both sides of its body, and a worktable is provided on top of the body. In this device, the output end of a hydraulic cylinder retracts, causing a first crossbar to slide along the inner wall of a first frame. This movement drives a first connecting rod and a second connecting rod, which in turn move two second crossbars along the inner wall of a second frame, thus moving the worktable upwards. This allows operators to stack cigarette packs from a higher position, requiring less physical effort compared to stacking them layer by layer from a lower position, thus saving labor. The operator grips the handlebars, starts the vehicle, and rotates the three wheels. When the vehicle reaches the desired stacking position, it is closed, and the operator stacks the cigarette packs on the worktable. This significantly reduces the time required compared to manual handling, thereby improving transport efficiency.

Description

Technical Field

[0001] This utility model relates to the field of tobacco bale transportation and palletizing technology at tobacco purchasing stations, and in particular to a lifting and transporting device for palletizing tobacco bales. Background Technology

[0002] Tobacco packs typically refer to packages containing tobacco leaves. After being packed, tobacco packs usually need to be transported to designated warehouses for storage. While in the warehouse, tobacco packs are usually stacked for easy storage. During stacking, lifting and transporting devices are usually used to facilitate the stacking process.

[0003] Currently, the transportation of tobacco bales for storage and palletizing at tobacco purchasing stations in various regions mostly relies on manual flatbed carts. This method requires a large workforce and places high demands on manpower. With the aging population, the availability of physically strong workers is decreasing, labor costs are rising, and employment risks are increasing. While tobacco bale transportation involves horizontal movement, palletizing requires vertical movement and demands both mental and physical strength. Traditional manual flatbed carts are no longer sufficient to meet current storage requirements, necessitating a more efficient transportation tool to change this situation. Field investigations show that transporting 20 tobacco bales on a flatbed cart from the warehouse to the palletizing location takes an average of 1440 seconds, and the average time for a single bale to travel from the warehouse to the palletizing location is as high as 72 seconds. This typically requires five people working together, resulting in high labor, time, and energy costs. The overall efficiency of tobacco bale transportation and palletizing is low, and manual transportation suffers from both high labor costs and labor shortages, making it inefficient and unable to meet current purchasing and storage needs. Summary of the Invention

[0004] This utility model aims to solve the problems existing in the prior art by providing a lifting and transporting device for stacking cigarette packages. Through the cooperation of the lifting mechanism and the support mechanism, it achieves the purpose of saving manual labor, and through the cooperation of the vehicle body and wheels, it achieves the purpose of rapid transportation.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: This lifting and transporting device for stacking cigarette packs includes a vehicle body and a handlebar. The handlebar is installed on the right side of the vehicle body, three wheels are installed under the vehicle body, a lifting mechanism is provided inside the vehicle body, multiple support mechanisms are provided under the vehicle body, grooves are machined on both sides of the vehicle body, and a worktable is provided on the top of the vehicle body.

[0006] To further improve the design, the lifting mechanism includes a hydraulic cylinder. A first crossbar is fixedly connected to the output end of the hydraulic cylinder. Both sides of the outer wall of the first crossbar are slidably connected to a first frame. The outer walls of the first frame are fixedly connected to the vehicle body. Both sides of the first crossbar are rotatably connected to a first connecting rod via bearings. The middle of each first connecting rod is movably connected to a second connecting rod via a pin. The upper part of the second connecting rod is rotatably connected to a second crossbar via a bearing. The upper part of each first connecting rod is rotatably connected to a worktable via a pin. The outer wall of the second crossbar is slidably connected to a second frame. The outer walls of the second frame are fixedly connected to the worktable. The lower part of the second connecting rod is movably connected to the vehicle body via a pin.

[0007] Further improvements include a fixed connection between the end of the hydraulic cylinder and the vehicle body.

[0008] In a further improvement, the support mechanism includes a curved plate, and a first sleeve is fixedly connected to the inner wall of each of the multiple curved plates. The inner wall of each first sleeve is slidably connected to a second sleeve, the inner wall of each second sleeve is slidably connected to a third sleeve, and the inner wall of each third sleeve is slidably connected to a vertical rod. Multiple threaded holes are machined on the second sleeve, the third sleeve, and the vertical rod. A locking block is fixedly connected to the bottom of each second sleeve, the third sleeve, and the vertical rod. The first sleeve, the second sleeve, and the third sleeve are all threadedly connected to bolts.

[0009] Further improvements include fixing the upper ends of the curved plates to the vehicle body and fixing the upper ends of the vertical rods to the worktable.

[0010] The beneficial effects of this utility model are as follows: Through the cooperation of the lifting mechanism and the support mechanism, the retraction of the hydraulic cylinder output end drives the first crossbar to slide along the inner wall of the first frame, thereby driving the first and second connecting rods to move. The movement of the first and second connecting rods drives the two second crossbars to move along the inner wall of the second frame, thus moving the worktable upwards. Simultaneously, the worktable moves the vertical rod upwards. When the locking block at the lower end of the vertical rod is in contact with the upper part of the inner wall of the third sleeve, it drives the third sleeve upwards, thereby moving the second sleeve. After the worktable stops, the operator screws multiple bolts into the corresponding threaded holes to fix the vertical rod, the third sleeve, and the second sleeve. This allows multiple vertical rods to support the four corners below the worktable, preventing the worktable from swaying when moved to a higher position, thus affecting the operator's working condition. Furthermore, the operator can perform stacking at a higher position, which requires less physical effort compared to standing at a lower position and stacking layer by layer, thereby saving manual labor.

[0011] By coordinating the vehicle body and wheels, the operator holds the handlebars, starts the vehicle, and drives the three wheels to rotate. When the vehicle body moves to the position where it needs to be stacked, it is shut off. The operator then stacks the cigarette packs on the workbench, which takes less time than manually handling them one by one, thus improving the efficiency of transportation.

[0021] See attached document Figure 1-7In this embodiment, a lifting and transporting device for stacking cigarette packs includes a vehicle body 1 and a handlebar 7. The handlebar 7 is installed on the right side of the vehicle body 1, and three wheels 6 are installed below the vehicle body 1. A lifting mechanism 5 is provided inside the vehicle body 1, and multiple support mechanisms 2 are provided below the vehicle body 1.

Rotary connection: The outer wall of the second crossbar 506 is slidably connected to the second frame 507, and the outer wall of the second frame 507 is fixedly connected to the worktable 3. The lower part of the second connecting rod 505 is movably connected to the vehicle body 1 through a pin. The output end of the hydraulic cylinder 501 moves, causing the first crossbar 502 to slide along the inner wall of the first frame 503, thereby causing the first connecting rod 504 and the second connecting rod 505 to move. The movement of the first connecting rod 504 and the second connecting rod 505 causes the two second crossbars 506 to move along the inner wall of the second frame 507, thereby causing the worktable 3 to move.

[0023] The support mechanism 2 includes a curved plate 201. The inner walls of multiple curved plates 201 are fixedly connected to a first sleeve 202. The inner walls of the first sleeves 202 are slidably connected to a second sleeve 203. The inner walls of the second sleeves 203 are slidably connected to a third sleeve 207.

Multiple threaded holes 205 are machined on the second sleeves 203, the third sleeves 207 and the vertical rod 208. A locking block 206 is fixedly connected to the bottom of the second sleeves 203, the third sleeves 207 and the vertical rod 208. The first sleeves 202, the second sleeves 203 and the third sleeves 207 are threadedly connected to bolts 204.

[0024] Working principle:

[0025] When using a lifting and transport device for stacking cigarette packages:

[0026] The operator places the cigarette packs to be transferred on the workbench 3 and secures them with ropes. Then, the operator holds the handlebars 7, starts the vehicle body 1, and drives the three wheels 6 to rotate. When the vehicle body 1 moves to the position where it needs to be stacked, the vehicle body 1 is turned off. Compared with the operator manually moving them one by one, it takes less time. Then the operator stacks the cigarette packs on the workbench 3.

[0027] When stacking needs to be performed at a higher position, the operator steps onto the workbench 3 by stepping on the groove 4. Then, the operator activates the hydraulic cylinder 501. The output end of the hydraulic cylinder 501 retracts, causing the first horizontal bar 502 to slide along the inner wall of the first frame 503, thereby moving the first connecting rod 504 and the second connecting rod 505. The movement of the first connecting rod 504 and the second connecting rod 505 causes the two second horizontal bars 506 to move along the inner wall of the second frame 507, thereby moving the workbench 3 upward. When the workbench 3 is moved to a position where the operator can stack at a higher position, the hydraulic cylinder 501 is deactivated. Simultaneously, the movement of the workbench 3 causes the vertical bar 208 to move upward (by default, multiple bolts 204 are not locked). When the locking block 206 at the lower end of the vertical bar 208... When it is in contact with the upper part of the inner wall of the third sleeve 207, it drives the third sleeve 207 to move upward, thereby driving the second sleeve 202 to move. When the worktable 3 stops, the operator screws multiple bolts 204 into the corresponding threaded holes 205, thereby fixing the vertical rod 208, the third sleeve 207 and the second sleeve 203. The multiple vertical rods 208 can support the four corners below the worktable 3 to prevent the worktable 3 from shaking when it moves to a higher position, which would affect the operator's working condition. Through the cooperation of the lifting mechanism 5 and the support mechanism 2, the operator can stack at a higher position. Compared with the operator standing at a lower position and stacking layer by layer, less physical strength is consumed, thus saving manual labor.

[0028] After the stacking is completed, the operator returns multiple bolts 204 to their initial positions and then resets the worktable 3 by controlling the hydraulic cylinder 501 for easy use next time.

[0029] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
