[0046] The core of this invention is to provide a suction cup device that can change position and orientation according to the arrangement of woven bags on a pallet to meet the needs of various stacking styles.

[0047] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0048] like Figure 1 and Figure 2 As shown in the figure, an embodiment of the present invention discloses a suction cup device, including a bracket 100, an adjustable suction cup module 200, a linear drive device 500, and a rotary drive device 600.

[0049] like Figure 2and 5 As shown, a slide rail 101 is provided on the bracket 100. The adjustable suction cup module 200 is arranged on the slide rail 101 via a connecting assembly. The connecting assembly includes a rotating device 300 that rotatably engages with the adjustable suction cup module 200 and a sliding device 400 disposed on the rotating device 300. The sliding device 400 slidably engages with the slide rail 101. The rotating device 300 allows the adjustable suction cup module 200 to rotate, thereby changing its orientation. The suction cup assembly 201 of the adjustable suction cup module 200 is used to adsorb goods. The suction cup assembly 201 is generally a long, narrow structure. The adjustable suction cup module 200 rotates under the action of the rotating device 300, adjusting the orientation of the suction cup assembly 201 for better adhesion to the goods. The rotation axis of the rotating device 300 is perpendicular to the adsorption surface of the suction cup assembly 201.

[0050] The sliding device 400 enables the adjustable suction cup module 200 to move linearly along the slide rail 101. The rotating device 300 can be of various types, such as bearings or shafts; the specific type is not limited here, and those skilled in the art can select according to actual needs. The sliding device 400 can also be of various types, such as a non-rotating slider or pulley, as long as it enables the adjustable suction cup module 200 to move linearly along the slide rail 101; its specific type is not limited here, and those skilled in the art can select according to actual needs.

[0051] like Figure 3 As shown, the linear drive device 500 is mounted on the bracket 100 and drives the adjustable suction cup module 200 to move linearly along the slide rail 101. It should be noted that there are various types of linear drive devices 500, such as drive cylinders, linear motors, hydraulic cylinders, etc. The specific type is not limited here, and those skilled in the art can select according to actual needs.

[0052] The rotary drive device 600 is connected to the adjustable suction cup module 200 and drives the adjustable suction cup module 200 to rotate along the rotating device 300. The rotary drive device 600 can be of various types, such as a drive cylinder or a drive motor. The specific type is not limited here, and those skilled in the art can select it according to actual needs.

[0053] The suction cup device disclosed in this invention features an adjustable suction cup module 200 arranged on a slide rail 101 via a connecting component. When the position of the adjustable suction cup module 200 differs from that of the goods being absorbed, a linear drive device 500 drives the adjustable suction cup module 200 to move linearly along the slide rail, thereby changing its position to meet the absorption requirements of the goods. When the direction of the adjustable suction cup module 200 differs from that of the goods being absorbed, a rotary drive device 600 drives the adjustable suction cup module 200 to rotate along a rotating device 300, thereby changing the direction of the suction cup assembly 201 of the adjustable suction cup module 200 to meet the absorption requirements of the goods. The suction cup device disclosed in this embodiment of the invention can flexibly change its position and direction, meeting the absorption requirements of goods with different palletizing styles.

[0054] like Figure 5 As shown, in a specific embodiment of the present invention, the rotating device 300 includes a bearing housing and a bearing disposed in the bearing housing. The adjustable suction cup module 200 is fixed in the bearing by a rotating shaft 301, so that the adjustable suction cup module 200 can rotate relative to the bearing housing by the rotating shaft. The bearing arrangement changes the sliding friction of the rotating shaft 301 to rolling friction when it rotates, reducing the friction and wear of the rotating shaft 301 and extending the service life of the rotating shaft 301.

[0055] The sliding device 400 is a hanging wheel, which is suspended inside the slide rail 101, allowing the adjustable suction cup module 200 to slide on the slide rail 101 via the hanging wheel. The hanging wheel reduces friction. The hanging wheel is fixedly connected to the bearing seat, and the adjustable suction cup module 200 is fixed in the bearing seat through the rotating shaft 301, thus realizing the connection between the hanging wheel and the adjustable suction cup module 200. The hanging wheel slides along the slide rail 101, thereby driving the adjustable suction cup module 200 to slide on the slide rail 101.

[0056] To prevent the linear drive device 500 and the rotary drive device 600 from affecting the rotation of the adjustable suction cup module 200 and the sliding of the adjustable suction cup module 200 along the slide rail 101, such as Figure 4 As shown, in a specific embodiment of the present invention, both the linear drive device 500 and the rotary drive device 600 are telescopic devices. The fixed end of the rotary drive device 600 is hinged to the hinge plate 302, meaning the rotary drive device 600 can rotate along the hinge axis. The hinge plate 302 is fixed to the bearing seat, thus keeping the hinge plate 302 stationary and preventing arbitrary rotation. There are various ways to fix the hinge plate 302 to the bearing seat, such as bolt connection, snap-fit ​​connection, welding connection, etc. The specific fixing method is not limited here; those skilled in the art can select according to the actual situation.

[0057] The extended end of the rotary drive device 600 is hinged to the adjustable suction cup module 200, and the extended end of the linear drive device 500 is hinged to the hinge plate 302. The fixed end of the linear drive device 500 is mounted on the bracket 100. That is, the linear drive device 500 is connected to the adjustable suction cup module 200 via the hinge plate 302. To avoid affecting the extension and retraction operation of the extended end of the rotary drive device 600, a clearance space is provided between the hinge plate 302 and the adjustable suction cup module 200.

[0058] When the adjustable suction cup module 200 is positioned differently from the goods being adsorbed, the extended end of the linear drive device 500 extends or retracts, driving the adjustable suction cup module 200 to move linearly along the slide rail 101 under the action of the hanging wheel, sliding away from or towards the linear drive device 500, thereby changing its position. The rotary drive device 600 moves linearly synchronously with the adjustable suction cup module 200. When the direction of the suction cup assembly 201 of the adjustable suction cup module 200 is different from the direction of goods adsorption, and a change of direction is required, the extended end of the rotary drive device 600 extends or retracts, causing the adjustable suction cup module 200 to rotate along the bearing seat, thereby changing the direction of the suction cup assembly 201.

[0059] To facilitate the assembly and disassembly of the connection between the sheave and the bearing housing, such as Figure 5 As shown, in a specific embodiment of the present invention, the hanger and the bearing seat are fixedly connected by a screw, with the hanger located at the first end of the screw. A first through hole is provided on the hinge plate 302, and a fixing hole is provided on the bearing seat. The second end of the screw passes through the first through hole and the fixing hole, and is fastened by a first locking nut and a second locking nut. The first locking nut is pressed against the side of the hinge plate 302 away from the bearing seat, and the second locking nut is pressed against the side of the bearing seat away from the hinge plate 302. The screw, the first locking nut, and the second locking nut lock together, making it convenient to install and disassemble the hinge plate 302 and the bearing seat. Of course, the hinge plate 302 and the bearing seat can also be connected by welding.

[0060] To simplify the structure of the suction cup device and facilitate its manufacturing, such as... Figure 5As shown, in a specific embodiment of the present invention, both the linear drive device 500 and the rotary drive device 600 are drive cylinders. The fixed end of the rotary drive device 600 is the cylinder body, which is hinged to the hinge plate 302. The extended end of the rotary drive device 600 is the piston rod, which is hinged to the adjustable suction cup module 200. A clearance space is provided between the hinge plate 302 and the adjustable suction cup module 200 to avoid affecting the extension and retraction of the piston rod. The fixed end of the linear drive device 500 is the cylinder body, which is fixed to the bracket 100, specifically through flanges, bolts, or other fasteners. The extended end of the linear drive device 500 is the piston rod, which is hinged to the hinge plate 302. The drive cylinder is a commonly used drive mechanism, which makes the suction cup device simple in structure and easy to process.

[0061] like Figure 1-3 As shown, the suction cup device disclosed in this invention comprises multiple adjustable suction cup modules 200. To avoid affecting the rotation of each adjustable suction cup module 200, the multiple adjustable suction cup modules 200 are arranged at intervals on the support 100. The interval between the adjustable suction cup modules 200 should ensure that they do not interfere with each other when rotating simultaneously, preventing adjacent adjustable suction cup modules 200 from being too close and affecting their rotation. Those skilled in the art will understand that the specific number of adjustable suction cup modules 200 can be selected according to actual conditions and is not limited here.

[0062] To meet the needs of different palletizing styles, such as Figure 5-7 As shown, based on the above embodiments, the suction cup device disclosed in this invention further includes at least one fixed suction cup module 700. The fixed suction cup module 700 is fixed to the bracket 100, meaning that the fixed suction cup module 700 cannot rotate or slide along the slide rail 101, and its position and orientation cannot be changed. It should be noted that the fixed suction cup module 700 and the adjustable suction cup module 200 have the same structure; the only difference is their connection method with the bracket 100. The specific number of fixed suction cup modules 700 can be selected according to different stacking style requirements. Those skilled in the art can freely combine the fixed suction cup module 700 and the adjustable suction cup module 200 according to their needs.

[0063] The goods are typically stacked on a pallet with three bags vertically in the first layer and two bags horizontally in the second layer, and so on, alternating between the two layers. To ensure the suction cup device can pick up two or three bags at a time, such as... Figure 5-7As shown, based on the above embodiments, the suction cup device disclosed in this invention has two adjustable suction cup modules 200 and one fixed suction cup module 700, with the fixed suction cup module 700 disposed between the two adjustable suction cup modules 200.

[0064] When the suction cup device needs to pick up three bags of goods at once, the adjustable suction cup modules 200 located on both sides are adjusted by the linear drive device 500 and the rotary drive device 600 so that the two adjustable suction cup modules 200 are oriented in the same direction as the fixed suction cup module 700, thus fulfilling the need for picking up the goods. When the suction cup device needs to pick up two bags of goods at once, the fixed suction cup module 700 remains stationary. The adjustable suction cup modules 200 located on both sides are adjusted by the linear drive device 500 and the rotary drive device 600. The rotary drive device 600 drives the two adjustable suction cup modules 200 to rotate along the rotating device 300, changing their direction so that the adjustable suction cup modules 200 are oriented in the same direction as the goods, maximizing the suction area. At the same time, the linear drive device 500 drives the adjustable suction cup modules 200 to slide along the slide rail, so that the position of the adjustable suction cup modules 200 corresponds to the position of the goods. After adjustment, the suction operation can begin.

[0065] The suction cup device disclosed in this invention, such as Figure 2 and Figure 6 As shown, the adjustable suction cup module 200 includes a suction cup assembly 201, a connecting plate 202, and a fixing plate 205.

[0066] The suction cup assembly 201 is used to adsorb goods, which can be of various types, such as woven bag goods and boxed goods. The suction cup assembly 201 is a commonly used suction cup device in the prior art, and its specific adsorption principle will not be elaborated here. The focus of this application is not to improve the structure of the suction cup assembly 201.

[0067] like Figure 2 and Figure 6 As shown, the connecting plate 202 is disposed on the top of the suction cup assembly 201. The top of the suction cup assembly 201 refers to the side opposite to the suction surface of the suction cup assembly 201. The suction cup assembly 201 is rotatably connected to the connecting plate 202 via a ball joint assembly 203. The ball joint assembly 203 allows the suction cup assembly 201 to rotate and swing at any angle around the center of the ball joint assembly 203, enabling the suction cup assembly 201 to rotate relative to the connecting plate 202 within a spatial range. The fixing plate 205 and the connecting plate 202 are connected by a connector 206. The rotating device 300 is disposed on the fixing plate 205, and the rotating drive device 600 is connected to the fixing plate 205.

[0068] The suction cup device disclosed in this invention has a suction cup assembly 201 rotatably connected to a connecting plate 202 via a ball joint assembly 203. When the surface of the goods to be adsorbed by the suction cup assembly 201 is uneven, the suction cup assembly 201 can adjust its angle according to the curvature of the surface of the goods under the action of the ball joint assembly 203, so that the suction cup assembly 201 fits better against the surface of the goods to be adsorbed, which greatly improves the adsorption success rate of the suction cup assembly 201.

[0069] To prevent the suction cup assembly 201 from rotating around a straight line perpendicular to its adsorption surface, i.e., to prevent the adsorption surface of the suction cup assembly 201 from rotating within the plane of its adsorption surface, and to ensure that the suction cup assembly 201 can only adjust its swing angle, based on the above embodiments, the adjustable suction cup module 200 disclosed in this invention may further include a limiting plate 204 disposed at the bottom of the connecting plate 202. The limiting plate 204 is provided with an anti-rotation groove, and the ball joint assembly 203 cooperates with the anti-rotation groove to restrict the suction cup assembly 201 from rotating around a rotation center line, which is a straight line perpendicular to the adsorption surface of the suction cup assembly 201.

[0070] In this embodiment of the invention, by setting a limiting plate 204, the suction cup assembly 201 can only swing in all directions around the center of the ball joint assembly 203, and cannot rotate in a straight line around the adsorption surface perpendicular to the suction cup assembly 201. This avoids the problem of goods falling off due to the suction cup assembly 201 rotating around the plane where the adsorption surface is located after adsorbing the goods, and ensures the stability of the structure after the suction cup assembly 201 adsorbs the goods.

[0071] like Figure 2 and Figure 6 As shown, the suction cup device disclosed in this embodiment of the invention includes a buffer guide rod 2061 and a reset elastic member 2062 in the connecting member 206. The first end of the buffer guide rod 2061 is fixed to the fixing plate 205, and the second end of the buffer guide rod 2061 is slidably engaged with the fixing plate 205, meaning the fixing plate 205 can slide along the buffer guide rod 2061. Correspondingly, the fixing plate 205 needs to be provided with sliding holes for sliding engagement with the buffer guide rod 2061.

[0072] To prevent the fixed plate 205 from sliding out of the buffer guide rod 2061, a limiting element is provided at the second end of the buffer guide rod 2061. The limiting element can have various designs; for example, it can be a limiting nut. The second end of the buffer guide rod 2061 can be provided with external threads, and the limiting nut engages with the threaded connection at the second end of the buffer guide rod 2061 to achieve the limiting function. Alternatively, a pin hole can be opened at the second end of the buffer guide rod 2061, and a locking pin can be inserted into the pin hole to achieve the limiting function. Those skilled in the art can choose the specific arrangement scheme according to the actual situation.

[0073] The reset elastic element 2062 is sleeved on the buffer guide rod 2061, with one end abutting against the connecting plate 202 and the other end abutting against the fixing plate 205. The reset elastic element 2062 plays a buffering role. When multiple adjustable suction cup modules 200 are working simultaneously, if multiple goods to be adsorbed are placed at different heights, the reset elastic element 2062 can offset the height difference between the goods to be adsorbed, ensuring that each adjustable suction cup module 200 can adsorb the surface of the goods to be adsorbed.

[0074] To prevent the adjustable suction cup module 200 from shaking excessively during movement after the suction cup assembly 201 has adhered to the goods, causing the goods to fall, such as... Figure 2 and Figure 6 As shown, based on the above embodiment, the adjustable suction cup module 200 also includes an anti-sway cylinder 207. The anti-sway cylinder 207 is disposed at the bottom of the fixing plate 205, and specifically, the cylinder body of the anti-sway cylinder 207 can be fixed to the fixing plate 205 by means of flanges, bolts, or other fasteners. The anti-sway cylinder 207 can be a regular cylinder or an electric cylinder.

[0075] After the suction cup assembly 201 has adhered to and secured the goods, to prevent the goods from falling due to excessive shaking during movement, the anti-sway cylinder 207 can be controlled in a first working state, i.e., the piston rod of the anti-sway cylinder 207 extends to abut against the suction cup assembly 201. When the suction cup assembly 201 has not adhered to the goods, to prevent the extension of the piston rod of the anti-sway cylinder 207 from affecting the compression of the reset elastic element 2062, the anti-sway cylinder 207 can be controlled in a second working state, i.e., the piston rod of the anti-sway cylinder 207 retracts to disengage from the suction cup assembly 201 without affecting the cushioning effect of the reset elastic element 2062.

[0076] To ensure the firmness of the connection between the fixing plate 205 and the connecting plate 202, and to further ensure that the adjustable suction cup module 200 avoids large-scale shaking that could cause the adsorbed goods to fall during movement after the suction cup assembly 201 has adsorbed the goods, based on the above embodiment, the number of connecting parts 206 is two, the number of anti-shake cylinders 207 is two, and the line connecting the two connecting parts 206 is perpendicular to the line connecting the two anti-shake cylinders 207. The cross arrangement makes the structure of the suction cup assembly 201 more stable after adsorbing the goods, ensuring the stability of the adjustable suction cup module 200 in adsorbing the goods during movement.

[0077] It should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
