Description

Technical Field

[0001] This utility model relates to the field of packaging box production equipment technology, and in particular to a handling mechanism and a feeding device. Background Technology

[0002] In the packaging box manufacturing industry, conveyor belts are key equipment for transferring finished and semi-finished products (hereinafter collectively referred to as "materials"). During the packaging box production process, materials typically need to be transferred from the conveyor belt of the previous process to the conveyor belt of the next process. However, differences in the timing and speed of the conveyor belts between the two processes lead to significant friction when materials pass between them. This friction easily causes scratches on the material surface, especially on materials that have undergone special treatment (such as those coated with a wear-resistant coating). Once scratched, the material usually fails to meet quality standards and is deemed a defective product. This not only significantly reduces product yield but also increases production line losses, resulting in unnecessary cost increases for the company. Furthermore, while traditional rocker-arm and horizontal robotic arms can be used to handle materials, their high cost and slow handling speed make them difficult to adapt to high-speed production lines. If these robotic arms are forced to be used, the production line speed needs to be reduced to match their normal operation, leading to a significant decrease in overall production efficiency.

[0029] Figure 1 A schematic diagram of a conveying mechanism 100 according to an embodiment of the present invention is shown below, in conjunction with... Figure 1 Provide a detailed description.

[0030] like Figure 1 As shown, the conveying mechanism 100 mainly includes a support column 110, an adsorption module 120, a first swing arm 130, a second swing arm 140, a connecting arm 150, and a drive module 160. The adsorption module 120 includes one or more suction cups 121. The support column 110, the first swing arm 130, the second swing arm 140, and the connecting arm 150 form a four-bar linkage. Driven by the drive module 160, this four-bar linkage can switch the adsorption module 120 between the material picking position and the material discharging position, thereby completing the material conveying.

[0031] Specifically, the support column 110 is arranged vertically to provide a mounting base and stable support for other components, ensuring the overall stability of the handling mechanism 100 during operation. The connecting arm 150 includes a first connecting part 151, a second connecting part 152, and a third connecting part 153 connected in sequence, wherein the third connecting part 153 is fixedly connected to the adsorption module 120. The first end of the first swing arm 130 is rotatably connected to the front side of the support column 110, and the second end of the first swing arm 130 is rotatably connected to the first connecting part 151 of the connecting arm 150. The first end of the second swing arm 140 is rotatably connected to the front side of the support column 110, and the second end of the second swing arm 140 is rotatably connected to the second connecting part 152 of the connecting arm 150. This structural design allows the first swing arm 130, the connecting arm 150, and the second swing arm 140 to be interconnected. Simultaneously, the first swing arm 130 can rotate around a first axis, and the second swing arm 140 can rotate around a second axis. Furthermore, the drive module 160 is connected to the first swing arm 130 and / or the second swing arm 140 and can output rotational power, thereby directly driving the first swing arm 130 and / or the second swing arm 140 to rotate around the corresponding axis (first axis / second axis). When the first swing arm 130 and / or the second swing arm 140 are driven to rotate, they will drive the connecting arm 150 to move, causing the adsorption module 120 to switch between the material picking position and the material discharging position. This allows for the rapid and accurate transfer of material from one conveyor belt (picking position) to another conveyor belt (discharging position), reducing friction during conveyor belt transfers and lowering the risk of surface scratches. This significantly improves product yield and provides higher reliability and quality assurance for the production process.

[0032] According to one embodiment of the present invention, such as Figure 1 and Figure 2 As shown, a first support hole 111 is provided on the support column 110 along the first axis, and a second support hole 112 is provided along the second axis. The conveying mechanism 100 also includes a first rotating shaft 171 and a second rotating shaft 172, wherein the first rotating shaft 171 is mounted in the first support hole 111 by a bearing and is fixedly connected to the first end of the first swing arm 130; the second rotating shaft 172 is mounted in the second support hole 112 by a bearing and is fixedly connected to the first end of the second swing arm 140. The drive module 160 includes a rotary driver 161, which is mounted on the support column 110 and can be one of a motor, a geared motor, a rotary electromagnet, a pneumatic motor (also known as a pneumatic motor), or a hydraulic motor.

[0033] In some embodiments, the output shaft of the rotary driver 161 is connected to the first rotating shaft 171 via a gear set, enabling the rotary driver 161 to drive the first rotating shaft 171 to rotate around a first axis. Furthermore, the output shaft of the rotary driver 161 is also connected to the second rotating shaft 172 via another gear set, enabling the rotary driver 161 to drive the second rotating shaft 172 to rotate around the first axis. It should be noted that the two gear sets mentioned here can be completely independent or share some gears; the specific configuration can be selected according to actual needs. Additionally, in other embodiments, belt pairs, chain pairs, or other transmission pairs can be used to replace the gear sets to achieve the transmission between the rotary driver 161 and the first rotating shaft 171 / second rotating shaft 172.

[0034] According to one embodiment of the present invention, such as Figure 1 As shown, the effective length of the first swing arm 130 is the same as the effective length of the second swing arm 140. The effective length of the first swing arm 130 refers to the distance from the connection point (first axis) between the first swing arm 130 and the support column 110 to the connection point (third axis) between the first swing arm 130 and the connecting arm 150. The effective length of the second swing arm 140 refers to the distance from the connection point (second axis) between the second swing arm 140 and the support column 110 to the connection point (fourth axis) between the second swing arm 140 and the connecting arm 150. Furthermore, the first swing arm 130 and the second swing arm 140 are parallel to each other, and the connecting arm 150 is parallel to the column. The column, the first swing arm 130, the second swing arm 140, and the connecting arm 150 together form a double-crank mechanism, and the connecting arm 150 remains vertical throughout the movement.

[0035] According to one embodiment of the present invention, such as Figure 1 As shown, weight-reducing holes 131 are provided on the first swing arm 130, the second swing arm 140, and the connecting arm 150. These weight-reducing holes 131 can effectively reduce the mass and motion inertia of the first swing arm 130, the second swing arm 140, and the connecting arm 150, allowing the drive module to drive them more easily, thereby improving the operating speed and accuracy of the conveying mechanism 100. In other embodiments, weight-reducing holes 131 can also be provided on only one or two of the first swing arm 130, the second swing arm 140, and the connecting arm 150, which can also improve the operating speed and accuracy of the conveying mechanism 100.

[0036] According to one embodiment of the present invention, such as Figure 1As shown, the adsorption module 120 also includes a mounting base 122, which can be configured as a flat plate structure or a frame structure, etc. It is fixedly connected to the lower end of the third connecting part 153 of the connecting arm 150 and extends forward. The aforementioned suction cup 121 is detachably connected to the mounting base 122, and the adsorption surface of the suction cup 121 is always located on the lower side of the mounting base 122. When the adsorption module 120 is in the material picking position, the adsorption surface of the suction cup 121 is in contact with the material, thereby reliably picking up the material. When the adsorption module 120 is in the material discharging position, the adsorption surface of the suction cup 121 separates from the material, thereby accurately and stably discharging the material.

[0037] Figure 2 A schematic diagram of an adsorption module 120 according to an embodiment of the present invention is shown. Figure 2 As shown, the suction cup 121 can be a vacuum suction cup 121, which may include a nut 1211, a suction head 1212, a spring 1213, and a hollow guide rod 1214. Correspondingly, one or more mounting holes (not shown) for mounting the suction cup 121 are provided on the mounting base 122. The guide rod 1214 is slidably inserted through the mounting hole, with both its upper and lower ends extending beyond the mounting base 122 (mounting hole). External threads are also provided at the upper and lower ends of the guide rod 1214. The suction head 1212 is threadedly connected to the lower end of the guide rod 1214 and communicates with it. The lower surface of the suction head 1212 is the suction surface for picking up materials. The spring 1213 is sleeved on the guide rod 1214, located between the suction head 1212 and the mounting base 122, and provides a cushioning function during the operation of the suction cup 121, reducing the impact force on the material. Nut 1211 is threaded onto the upper end of guide rod 1214 to secure suction cup 121 to mounting base 122, preventing suction cup 121 from detaching from mounting base 122. Simultaneously, by tightening nut 1211, the position of suction head 1212 and the compression of spring 1213 can be adjusted, thereby achieving precise adjustment of the buffering effect of suction cup 121 to adapt to the handling needs of different materials. Optionally, a linear bearing is provided between guide rod 1214 and mounting base 122 to prevent suction cup 121 from jamming and reduce frictional loss.

[0038] Considering that the handling mechanism 100 may impact the materials and conveyor belt when picking up and placing materials, and will also be subject to corresponding reaction forces, a suction cup 121 with buffering capacity can be considered to reduce the impact force, prevent material damage, and improve the yield of finished products. At the same time, a support member 190 can also be considered to be provided between the mounting base 122 and the connecting arm 150 to enhance the connection stability between the mounting base 122 and the connecting arm 150 and the overall structural strength. Figure 3 A schematic diagram of a support member 190 according to an embodiment of the present invention is shown. Figure 3As shown, the support member 190 can be a sheet metal structure, which includes a horizontal plate 191, a vertical plate 192 and a reinforcing rib 193 connected to each other. The horizontal plate 191 is fixedly connected to the upper side of the mounting base 122, and the vertical plate 192 is fixedly connected to the front side of the connecting arm 150.

[0039] According to one embodiment of the present invention, such as Figure 1 As shown, the conveying mechanism 100 may further include a vacuum generator 180, which can be mounted on the support column 110. The vacuum generator 180 is provided with an air inlet and an air outlet, wherein the air inlet of the vacuum generator 180 is connected to the guide rod 1214 of each suction cup 121 (guide rod 1214) via a gas pipeline (e.g., a hose). By controlling the operation and stop of the vacuum generator 180, the suction cups 121 can be used to pick up and release materials. In some embodiments, the vacuum generator 180 may also be mounted on the connecting arm 150 or the mounting base 122.

[0040] Compared with existing technologies, the embodiments of this utility model provide a conveying mechanism 100, which can quickly and accurately transfer materials from one conveyor belt to another. This reduces friction between materials during conveyor belt transfers, lowers the risk of surface scratches, and significantly improves product yield, providing higher reliability and quality assurance for the production process. Furthermore, the conveying mechanism 100 features a simple and efficient structural design, equipped with only one drive module 160. This not only significantly reduces manufacturing costs but also greatly improves drive and transmission efficiency, enabling faster conveying speeds and adapting to high-speed production lines.

[0041] Figure 4 A schematic diagram of a feeding device 200 according to an embodiment of the present invention is shown below. Figure 4 Provide a detailed description.

[0042] like Figure 4 As shown, the feeding device 200 mainly includes a conveyor 210, a positioning block 220, and a conveying mechanism 100. The conveyor 210 can be a belt conveyor 210, a chain conveyor 210, a roller conveyor 210, etc. The following description uses a belt conveyor 210 as an example. The conveyor 210 can transport materials along a first direction, and in particular, can intermittently transport materials along the first direction. The positioning block 220 is located at the end of the conveyor 210 and is used to accurately position the material at the picking position to facilitate picking by the conveying mechanism 100. The conveying mechanism 100 is located near the end of the conveyor 210 and is used to transport the material from the picking position to the discharging position (e.g., onto another conveyor).

[0043] According to one embodiment of the present invention, such as Figure 4 As shown, the feeding device 200 may further include two limit stops 230 and multiple adjustable supports 240. Both limit stops 230 are located above the conveyor 210 and extend along a first direction. A channel for material passage is formed between the two limit stops 230, guiding the material accurately to the picking position. Furthermore, each of the two limit stops 230 is fixed to the conveyor 210 by one or more adjustable supports 240. These adjustable supports 240 allow for flexible adjustment of the position and height of the limit stops 230, enabling them to adapt to materials of different specifications and further enhancing the versatility and flexibility of the feeding device 200.

[0044] According to one embodiment of the present invention, such as Figure 4 As shown, the feeding device 200 also includes a photoelectric sensor 250. The photoelectric sensor 250 is located at the end of the conveyor 210 and can project a detection beam towards the material pick-up position to detect whether material is present at that position. By using the detection results of the photoelectric sensor 250 to precisely control the conveying mechanism 100, the situation where the conveying mechanism 100 runs empty due to a lack of material at the pick-up position can be avoided, thereby significantly improving the operating efficiency and reliability of the entire feeding device 200.

[0045] Compared with the prior art, the embodiments of this utility model also provide a feeding device 200, which can stably and accurately transport materials to the next process.

[0046] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
