Description

Technical Field

[0001] This utility model relates to a dual-station suction cup independent lifting operation mechanism, belonging to the technical field of cigarette sorting equipment in the tobacco industry. Background Technology

[0002] Currently, in the intelligent logistics of commercial tobacco, some cartons of cigarettes are packaged in flexible boxes. Flexible boxes are a type of reusable green packaging box. They are usually stacked in a certain quantity and then transported to a designated workstation where they are picked up by a suction cup in a single operation. However, in practice, the height at which the suction cup picks up the stacked flexible boxes is not fixed due to the stacking of the boxes. Since the existing technology generally uses a cylinder assembly to achieve a relatively fixed lifting height for the suction cup, many peripheral auxiliary solutions have to be adopted to ensure that the gripping position of the flexible box is relatively fixed. These auxiliary solutions often lead to a high rate of damage to the flexible boxes, high energy consumption of the equipment, and high maintenance costs. Summary of the Invention

[0003] To address the aforementioned technical problems, this utility model provides a dual-station suction cup independent lifting mechanism. Through the structural design of the vertical lifting component, this dual-station suction cup independent lifting mechanism can effectively ensure the gripping of stacked elastic boxes at non-fixed height positions and effectively avoid redundant position detection methods, thereby greatly simplifying the overall structure and effectively reducing the elastic box damage rate, equipment operating energy consumption, and maintenance costs.

Detailed Implementation

[0018] The technical solution of this utility model is further described below, but the scope of protection is not limited to what is described.

[0019] The first embodiment of this utility model relates to, for example... Figure 1 The illustrated dual-station suction cup independent lifting mechanism includes a vertical lifting assembly 2. The vertical lifting assembly 2 is vertically mounted on a horizontal lifting mounting frame 1 and can be moved left and right by the lifting mounting frame 1. The lifting mounting frame 1 is fixed to an external frame. A suction cup assembly 3 is mounted at the bottom of the vertical lifting assembly 2. The suction cup assembly 3 has multiple vacuum suction cups 301 for picking up materials at its bottom. The vertical lifting assembly 2 has a lifting synchronous belt 205, and a lower synchronous belt pulley 209 is wound around the lifting synchronous belt 205. A servo drive assembly 210 drives the lower synchronous belt pulley 209 to rotate, thereby driving the vertical lifting assembly 2 and the suction cup assembly 3 to lift and lower.

[0020] The second embodiment of this utility model is largely the same as the first embodiment, except that the servo drive component 210 is mounted and fixed on the lifting mounting frame 1.

[0021] Furthermore, the power end of the servo drive assembly 210 is equipped with a drive pulley 208, and an upper synchronous belt guide pulley 207 is installed above the lower synchronous belt guide pulley 209 and is located on the same vertical plane as the lower synchronous belt guide pulley 209. The upper synchronous belt guide pulley 207, the drive pulley 208, and the lower synchronous belt guide pulley 209 form the apex of a triangle. The lifting synchronous belt 205 goes from the upper synchronous belt guide pulley 207 to the drive pulley 208 and then out through the lower synchronous belt guide pulley 209.

[0022] Furthermore, a stabilizing seat 206 is fixed above the upper timing belt pulley 207 for auxiliary stabilization.

[0023] The third embodiment of this utility model is largely the same as the first embodiment, except that the vertical lifting component 2 is composed of an aluminum alloy profile 201, the lifting synchronous belt 205 is wrapped around the aluminum alloy profile 201 in a loop on the front and back of the mounting surface of the lifting mounting frame 1, the aluminum alloy profile 201 has linear guide rails 202 on both sides facing the lifting synchronous belt 205, and a slider mounting plate 101 is mounted on the linear guide rails 202 through the slider 102, and the lifting mounting frame 1 is fixedly mounted on the slider mounting plate 101.

[0024] Furthermore, polyurethane buffer blocks 203 are fixed on the aluminum alloy profile 201 at positions directly above and below the slider mounting plate 101 for limiting movement.

[0025] Furthermore, a driven component 204 is installed on the top of the aluminum alloy profile 201 for the lifting synchronous belt 205 to bypass, and a driven component 212 is installed on the bottom of the aluminum alloy profile 201 for the lifting synchronous belt 205 to bypass.

[0026] Furthermore, a limit seat 211 is fixed on the aluminum alloy profile 201 at a position below the lower synchronous belt pulley 209 for auxiliary limiting.

[0027] The fourth embodiment of this utility model is largely the same as the first embodiment, except that the suction cup assembly 3 is composed of a mounting housing 303, the bottom of the mounting housing 303 has a rectangular plane, and the vacuum suction cups 301 are arranged in a symmetrical array on the bottom plane of the mounting housing 303.

[0028] Furthermore, a telescopic detection block 302 is installed at the bottom of the mounting housing 303, located in the middle of the distribution of the vacuum suction cups 301. The height of the telescopic detection block 302 in its naturally extended state is equivalent to that of the vacuum suction cups 301.

[0029] The fourth embodiment of this utility model, in conjunction with the above embodiments, mainly includes a lifting mounting frame 1, a vertical lifting assembly 2, and a suction cup assembly 3. A slider mounting plate 101 is mounted on the lifting mounting frame 1, and a slider 102 is mounted on the slider mounting plate 101. A linear guide rail 202 is mounted on the vertical lifting assembly 2. The slider 102 slides on the linear guide rail 202 as a guide for the vertical lifting assembly 2. Simultaneously, polyurethane buffer blocks 203 are installed at both ends of the linear guide rail 202 to limit the highest and lowest points of the vertical lifting. The vertical lifting assembly 2 uses an aluminum alloy profile 201 as the mounting component. Synchronous belt driven assembly one 204 and synchronous belt driven assembly two 212 are respectively mounted on the top and bottom of the aluminum alloy profile 201. Simultaneously, an upper synchronous belt pulley 207 and a lower synchronous belt pulley 209 are mounted on the lifting mounting frame 1. A drive pulley 208 is mounted on the output end of the servo drive assembly 210. The lifting synchronous belt 205 passes through the drive pulley 208, the upper synchronous belt pulley 207, the lower synchronous belt pulley 209, the synchronous belt driven assembly one 204, and the synchronous belt driven assembly two 212, forming a loop. The two ends of the synchronous belt are bolted to designated positions on the aluminum alloy profile 201 using synchronous belt pressure plates. A synchronous belt tensioning device is mounted on the corresponding synchronous belt pulley 207 to tension the synchronous belt. Thus, a single vertical lifting assembly 2 achieves its lifting and lowering through the forward and reverse rotation of the servo drive assembly 210. Simultaneously, a suction cup assembly 3 is installed at the end of each vertical lifting component 2. A vacuum generator is controlled by a solenoid valve on the suction cup assembly 3. The operation of the vacuum generator controls the operation of the vacuum suction cup 301. The suction cup guide rod is telescopic, adapting to uneven object surfaces. The operation of the vacuum suction cup is determined by the telescopic detection block 302, and each vacuum suction cup 301 is equipped with a shut-off valve. When a single vacuum suction cup 301 fails to reach the working surface, its operation is cut off, ensuring that at least 4 out of the 8 vacuum suction cups 301 are operational. Similarly, two identical vertical lifting components 2 are installed on the aluminum alloy profile 201. Each set operates independently, waiting for each other after suction and grabbing. Once both are complete, the next operation can proceed.
