For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0045] Liquefied gas is currently used by nearly 200 million people in China, and a large number of liquefied gas cylinders are transported by trucks every day. The steel cylinders in the truck are generally transported in the form of two layers stacked above and below, which can improve the transportation capacity. However, when the steel cylinders are stacked, the safety hazard of the steel cylinders falling due to unstable stacking may occur. In addition, the steel cylinders falling may produce sparks, which may cause the explosion of flammable gas and cause serious accidents.

[0046] Based on the above considerations, in order to solve the problem of unstable stacking of the related art which may cause the steel cylinders to fall, a cylinder stacking device is designed, which uses a lifting mechanism to act on the bottle body. When the bottle body moves to the bottle holding area of the main frame, the bottle holding mechanism and the bottle supporting mechanism act on the bottle body in the bottle holding area at different positions in the direction of gravity, so that when the driving mechanism drives the lifting mechanism to lift to lift the bottle body for stacking, the bottle body can move stably, thereby effectively reducing the probability of the bottle body falling due to unstable stacking.

[0047] In the following, the cylinder stacking device provided by the present application will be described in detail according to specific embodiments.

[0048] Please refer to Figures 1 to 7 The embodiment of the present application provides a bottle stacking device 1000, which comprises a support frame 100 and a lifting mechanism 200, and the support frame 100 is provided with a driving mechanism 300; the lifting mechanism 200 comprises a main frame 210, a bottle holding mechanism 230 and a bottle supporting mechanism 240; the output end of the driving mechanism 300 is connected with the main frame 210, and the driving mechanism 300 is configured to drive the main frame 210 to move up and down; the main frame 210 comprises a top support 211 and side supports 212 arranged at opposite ends of the top support 211, and a bottle holding area 213 is formed between the top support 211 and the two side supports 212 at the opposite ends; in the direction of gravity G, the bottle holding mechanism 230 and the bottle supporting mechanism 240 are sequentially and spacedly arranged on the side supports 212, and the bottle holding mechanism 230 and the bottle supporting mechanism 240 are configured to jointly act on the bottle body 2000 located in the bottle holding area 213.

[0049] The support frame 100 is used as the basic structure of the bottle stacking device 1000, and is used to support the lifting mechanism 200, so that the lifting mechanism 200 moves up and down on the support frame 100. In some embodiments, the support frame 100 can be a gantry structure.

[0050] The driving mechanism 300 is arranged on the support frame 100, and is used to drive the lifting mechanism 200 to move up and down. Optionally, the driving mechanism 300 comprises but is not limited to a driving cylinder, a driving hydraulic cylinder, a roller screw driving structure and the like. The driving mechanism 300 can be fixedly assembled on the support frame 100 by fasteners.

[0051] The lifting mechanism 200 is used to act on the bottle body 2000 to drive the bottle body 2000 to move up and down synchronously, and comprises the main frame 210, the bottle holding mechanism 230 and the bottle supporting mechanism 240.

[0052] The main frame 210 is used as the main part of the lifting mechanism 200, and is used to connect the driving mechanism 300 and to bear and install the bottle holding mechanism 230 and the bottle supporting mechanism 240. The main frame 210 comprises the top support 211 and the side supports 212 arranged at opposite ends of the top support 211, so that the top support 211 and the two side supports 212 at the opposite ends are combined to form a "U" type structure. The space between the top support 211 and the two side supports 212 at the opposite ends forms the bottle holding area 213. When the bottle body 2000 moves into the bottle holding area 213, the bottle holding mechanism 230 and the bottle supporting mechanism 240 can position and grab the bottle body 2000 in the bottle holding area 213, so that the bottle body 2000 can move up and down synchronously with the whole lifting mechanism 200.

[0053] The bottle holding mechanism 230 and the bottle supporting mechanism 240 are sequentially and spacedly arranged on the side support 212 in the gravity direction G, so that the bottle holding mechanism 230 and the bottle supporting mechanism 240 can position and grab the bottle body 2000 at different positions in the gravity direction G, thereby effectively improving the stability of the bottle body 2000 when the bottle body 2000 is lifted and stacked, and further improving the stability of the bottle body 2000 when the bottle body 2000 is stacked on another bottle body 2000, so as to reduce the risk of falling of the bottle body 2000.

[0054] It should be understood that the bottle supporting mechanism 240 is located at the bottom in the gravity direction G, and is used to support the bottle body 2000. The bottle holding mechanism 230 is located at the middle in the gravity direction G, and is used to hold the body of the bottle body 2000.

[0055] The bottle stacking device 1000 provided by the embodiment of the present application uses the lifting mechanism 200 to act on the bottle body 2000. When the bottle body 2000 moves to the bottle holding area 213 of the main frame 210, the bottle holding mechanism 230 and the bottle supporting mechanism 240 jointly act on the bottle body 2000 in the bottle holding area 213 at different positions in the gravity direction G, so that when the lifting mechanism 200 is lifted by the driving mechanism 300 to lift the bottle body 2000 for stacking, the bottle body 2000 can move stably, thereby effectively reducing the probability of falling of the bottle body 2000 due to unstable stacking.

[0056] Please refer to Figures 1 to 7 In some embodiments, the bottle holding mechanism 230 includes a bottle holding cylinder 231 rotationally arranged on each side support 212 and a bottle holding claw 232 rotationally connected to each side support 212. The output end of the bottle holding cylinder 231 is arranged in the gravity direction G, and the output end of the bottle holding cylinder 231 is rotationally connected to the corresponding bottle holding claw 232. The bottle holding cylinder 231 is configured to drive the bottle holding claw 232 to rotate to a folded state abutting the side support 212, or to a bottle holding state perpendicular to the side support 212.

[0057] The bottle holding cylinder 231 is rotationally arranged on the side support 212. The side of the bottle holding cylinder 231 away from the output end can be hingedly connected to the side support 212, for example, connected to a side wall surface of the side support 212 facing the bottle holding area 213.

[0058] The bottle gripping claws 232 are rotationally connected to the side supports 212. Alternatively, the bottle gripping claws 232 can be hingedly connected to a side wall of the side supports 212 towards the bottle gripping area 213. The bottle gripping claws 232 can have any configuration, such as an arc-shaped structure or a rectangular structure. In some embodiments, the bottle gripping claws 232 can have a plate structure, and a side portion of the bottle gripping claws 232 hingedly connected to the side supports 212 is rectangular, and the other side portion of the bottle gripping claws 232 away from the hingedly connected side portion is arc-shaped. When rotated to the bottle gripping state, the arc-shaped portion of the bottle gripping claws 232 can abut against the side wall of the bottle 2000 or form a gap with the side wall of the bottle 2000.

[0059] The output end of the bottle gripping cylinder 231 is arranged along the gravity direction G, and the output end of the bottle gripping cylinder 231 is rotationally connected to the corresponding bottle gripping claw 232. In this way, the bottle gripping cylinder 231 can drive the bottle gripping claw 232 to rotate around the hingedly connected portion of the side support 212 through the extension and contraction of the output end of the bottle gripping cylinder 231. When the output end of the bottle gripping cylinder 231 is extended, the output end of the bottle gripping cylinder 231 can drive the bottle gripping claw 232 to rotate around the hingedly connected portion of the side support 212 towards the gravity direction G to substantially abut against the side support 212, at which time the bottle gripping claw 232 is in the retracted state and does not perform the bottle positioning and clamping operation. When the output end of the bottle gripping cylinder 231 is retracted, the output end of the bottle gripping cylinder 231 can drive the bottle gripping claw 232 to rotate around the hingedly connected portion of the side support 212 away from the gravity direction G to be perpendicular to the side support 212, at which time the bottle gripping claw 232 is in the bottle gripping state, and the end portion of the bottle gripping claw 232 away from the hingedly connected portion of the side support 212 is used to position and clamp the bottle 2000. It should be understood that the above-mentioned perpendicularity of the bottle gripping claw 232 to the side support 212 refers to the relative two sides of the bottle gripping claw 232 in the thickness direction forming a verticality with the length direction of the side support 212.

[0060] It should be understood that the bottle gripping cylinder 231 and the bottle gripping claw 232 are arranged on the two side supports 212 at opposite ends of the top support 211, so that the bottle gripping cylinders 231 on the two side supports 212 can synchronously drive the bottle gripping claws 232 connected thereto to rotate to the bottle gripping state, and are collectively used to position and clamp the bottle 2000.

[0061] In this way, the bottle gripping mechanism 230 can drive the bottle gripping claws 232 to rotate and switch to the retracted state or the bottle gripping state through the bottle gripping cylinder 231, so as to achieve the purpose of retracting the bottle gripping claws 232 to the side supports 212 or positioning and clamping the bottle 2000 perpendicular to the side supports 212.

[0062] Please refer to Figures 1 to 7In some embodiments, the bottle gripping claws 232 are provided with two positioning protrusions 2321, which abut against the outer surface of the bottle body 2000 in the bottle gripping state.

[0063] It should be understood that when the bottle gripping claws 232 are in the bottle gripping state, the positioning protrusions 2321 are used to abut on the outer surface of the bottle body 2000 to achieve positioning clamping of the bottle body 2000.

[0064] In this way, the two bottle gripping claws 232 provided on the two side supports 212 are provided with four positioning protrusions 2321 in total, and the four positioning protrusions 2321 form a four-point symmetrical balanced structure for the bottle body 2000 to achieve positioning of the arc-shaped bottle body 2000, and can effectively adapt to various abnormal states of the bottle body 2000, such as overall skewing of the bottle body 2000, and can automatically align and perform radial positioning of the bottle body 2000 in any initial state, so that the cylindrical bottle body 2000 remains in the same plane in the radial direction, thereby improving the stability during bottle stacking.

[0065] Optionally, the positioning protrusions 2321 can be, but are not limited to, positioning blocks, positioning rollers, etc. For example, the positioning protrusions 2321 are described as positioning rollers. The four positioning rollers abut against the arc-shaped outer wall surface of the bottle body 2000 and can freely rotate, so that the bottle body 2000 can be radially positioned by the four positioning rollers, and the bottle body 2000 can move up and down in the axial direction to cooperate with the bottle supporting mechanism 240 and the bottle pressing mechanism 220 to adjust the positioning in the height direction.

[0066] Please refer to Figures 1 to 7 In some embodiments, the bottle body 2000 includes a bottle body 2100 and a base 2200 located at the bottom of the bottle body 2100, and the diameter of the base 2200 is smaller than that of the bottle body 2100. The bottle supporting mechanism 240 includes two supporting members 241 provided on the side supports 212 at both ends, and the distance between the two supporting members 241 is greater than the diameter of the base 2200 and smaller than the diameter of the bottle body 2100, and the two supporting members 241 jointly act on the bottom of the bottle body 2100.

[0067] It should be understood that the bottle body 2000 for bottle stacking includes a bottle body 2100 and a base 2200, and the bottle body 2100 and the base 2200 are respectively in the form of a barrel, and the diameter of the base 2200 is smaller than that of the bottle body 2100. The bottle supporting mechanism 240 is used to support the bottom of the bottle body 2100 on the periphery of the base 2200.

[0068] The bottle-supporting mechanism 240 includes two support members 241 respectively disposed on the side supports 212 at both ends; optionally, the support members 241 may be, but are not limited to, support blocks, support protrusions, support brackets, support plates, and other configurations. For example, taking a support block as an example, the two support blocks disposed on the side supports 212 at both ends jointly support the bottom of the bottle body 2100.

[0069] The distance between the two support members 241 is greater than the diameter of the base 2200 and less than the diameter of the bottle body 2100. In this way, the bottle body 2000 can be directly transported to the bottle holding area 213. The base 2200 of the bottle body 2000 can move directly between the two support members 241, and the projection of the two support members 241 in the direction of gravity G is located within the bottle body 2100 of the bottle body 2000. When the support members 241 move synchronously with the side support 212, the support members 241 can lift the bottle body 2100 and move synchronously.

[0070] Please refer to Figures 1 to 7 In some embodiments, the support member 241 includes a support body 2411 and two support parts 2412 disposed on the support body 2411. The support body 2411 is disposed on the side bracket 212, and the two support parts 2412 are supported on the bottom of the bottle body 2100.

[0071] The supporting body 2411 refers to the part that is directly connected and fixed to the side bracket 212; the supporting part 2412 refers to the part that is set on the supporting body 2411 and is used to support the bottom of the bottle body 2100 of the bottle body 2000.

[0072] Optionally, the supporting body 2411 can be, but is not limited to, a plate structure, a bracket structure, a block structure, etc., and the supporting body 2411 can be fixedly connected to the bottom end of the side bracket 212 by means of fastener connection, welding, etc. The support part 2412 can be, but is not limited to, a support block, a support plate, a support column, etc., and the support part 2412 can be fixedly connected to the supporting body 2411 by means of welding, fastener connection, etc. For example, in some embodiments, the support part 2412 can be a support block, and the end of the support block that abuts against the bottom of the bottle body 2100 is arc-shaped, so that the support block fits the bottle body 2100 better; in this way, the four support blocks on the two supporting members 241 on the two side brackets 212 can be used together to position and support the bottle body 2100, which can effectively adapt to various abnormal states such as tilting, and enable the bottle body 2000 to automatically align itself in any initial state and maintain a vertical state along the direction of gravity G, so as to facilitate subsequent stable bottle stacking operations.

[0073] Please refer to Figures 1 to 7In some embodiments, the bottle stacking device 1000 further includes a bottle pressing mechanism 220, which is disposed on the side support 212. In the direction of gravity G, the bottle pressing mechanism 220 is located above the bottle holding mechanism 230. The bottle pressing mechanism 220 includes a bottle pressing cylinder 221 and a bottle pressing component 222. The bottle pressing cylinder 221 is fixedly disposed on the two side supports 212 by a mounting bracket 223. The output end of the bottle pressing cylinder 221 faces the direction of gravity G. The output end of the bottle pressing cylinder 221 is connected to the bottle pressing component 222. The bottle pressing component 222 is configured to move to abut against the bottle body 2000 located in the bottle holding area 213.

[0074] Among them, the bottle pressing mechanism 220 is located at the top in the direction of gravity G. The bottle pressing mechanism 220 is used to press the bottle body 2000 in the direction of gravity G so that the bottle body 2000 is stably clamped between the bottle pressing mechanism 220 and the bottle supporting mechanism 240.

[0075] The bottle-pressing component 222 applies a force to the bottle body 2000 along the direction of gravity G, and works in conjunction with the support component 241 to clamp the bottle body 2000, thereby ensuring the stability of the bottle body 2000 during the movement and stacking of bottles. Optionally, the bottle-pressing component 222 may be, but is not limited to, a pressing plate, a pressing block, or similar structure; exemplaryly, in some embodiments, the bottle-pressing component 222 may be a plate structure, the surface of which can move to abut against the bottle body 2000 to perform the bottle-pressing operation.

[0076] The bottle-pressing cylinder 221 is fixedly mounted on two side brackets 212 via mounting brackets 223, with the output end of the bottle-pressing cylinder 221 facing the direction of gravity. Thus, the output end of the bottle-pressing cylinder 221 can drive the bottle-pressing component 222 to move by extension or retraction. For example, the output end can be extended to drive the bottle-pressing component 222 to move toward the bottle body 2000 along the direction of gravity G and apply pressure to the bottle body 2000, or the output end can be retracted to drive the bottle-pressing component 222 away from and release the bottle body 2000.

[0077] Please refer to Figures 1 to 7 In some embodiments, a cushioning pad 224 is provided on the surface of the bottle press 222.

[0078] Optionally, the cushioning pad 224 may be, but is not limited to, a cushioning structure with a certain degree of elasticity, such as a rubber cushioning pad, a silicone cushioning pad, or a foam cushioning pad.

[0079] With this configuration, when the bottle pressing component 222 applies pressure to the bottle body 2000, the buffer pad 224 directly contacts the bottle body 2000, thereby avoiding the problem of collision damage caused by rigid contact between the bottle pressing component 222 and the bottle body 2000.

[0080] Please refer to Figures 1 to 7In some embodiments, a guide structure 110 is provided on the support frame 100, and the side bracket 212 is slidably connected to the support frame 100 through the guide structure 110.

[0081] The guide structure 110 may be, but is not limited to, a guide rail or a slide rail. For example, in some embodiments, the guide structure 110 may be a linear guide rail, which may be mounted on the support frame 100, and the slider of the linear guide rail is connected to the side bracket 212, so that the side bracket 212 and the bottle pressing mechanism 220, bottle holding mechanism 230 and bottle supporting mechanism 240 provided on the side bracket 212 can move up and down smoothly, thereby reducing the probability of tipping over during the stacking of bottles.

[0082] Please refer to Figures 1 to 7 In some embodiments, the bottle stacking device 1000 further includes a transfer mechanism (not shown in the figure), which is located below the support frame 100 and is used to transfer the bottle body 2000.

[0083] Optionally, the conveying mechanism may be, but is not limited to, a chain conveyor, a roller conveyor, a belt conveyor, etc. The conveying mechanism is located below the support frame 100, so that the conveying mechanism can convey the bottle 2000, so that the bottle 2000 is conveyed and moved to the bottle holding area 213, and the bottle stacking operation is performed in the bottle holding area 213 by the lifting component.

[0084] For example, in some embodiments, the support frame 100 may be a gantry frame, in which case the lifting mechanism 200 may be disposed in the hollow portion of the gantry frame, and the conveying mechanism may be disposed at the bottom of the hollow portion of the gantry frame. In this way, the lifting mechanism 200 can lift the bottle 2000 above the conveying mechanism located in the hollow portion of the gantry frame to achieve bottle stacking operation.

[0085] Please refer to Figure 8 In some embodiments, the bottle stacking device 1000 further includes a controller (not shown), a toggle switch 400, and a bottle stopper 500, which are disposed above the transmission mechanism. The transmission mechanism has a transmission direction X, in which the toggle switch 400 and the bottle stopper 500 are located upstream and downstream of the bottle holding area 213. The controller is electrically connected to the toggle switch 400, the bottle stopper 500, the drive mechanism 300, the bottle pressing mechanism 220, the bottle holding mechanism 230, and the bottle supporting mechanism 240.

[0086] The controller refers to a control unit such as a microcontroller or PLC that can implement command control. The controller is electrically connected to the toggle switch 400, the bottle stopper 500, the drive mechanism 300, the bottle pressing mechanism 220, and the bottle holding mechanism 230. In this way, the controller can receive the electrical signal from the toggle switch 400 to control the bottle stopper 500, the drive mechanism 300, the bottle pressing mechanism 220, and the bottle holding mechanism 230 accordingly, so as to automate the bottle stacking operation.

[0087] The toggle switch 400 controls the circuit by moving its lever (usually a movable rod-like part). In the transmission direction X, the toggle switch 400 is located upstream and downstream of the bottle-holding area 213. Thus, when the bottle 2000 is transported to or from the bottle-holding area 213 by the transmission mechanism, the toggle switch 400 can be moved to send a command to the controller, enabling the controller to receive the command and perform corresponding control operations.

[0088] Bottle stopper 500 refers to a blocking structure used to block bottles 2000 being transported on the conveying mechanism and stop them at their current position. Optionally, bottle stopper 500 may include a driving member and a stop bar connected to the driving member. The driving member can move the stop bar into the conveying path of the conveying mechanism to achieve the blocking effect, or move the stop bar away from the conveying path of the conveying mechanism, so that the bottle 2000 can continue to be transported by the conveying mechanism. In the conveying direction X, bottle stopper 500 is located upstream and downstream of bottle holding area 213. Thus, bottle stopper 500 can prevent bottles 2000 from entering bottle holding area 213, or prevent bottles 2000 in bottle holding area 213 from moving out.

[0089] It should be understood that the aforementioned transmission direction X refers to the direction in which the transmission mechanism transports the bottle 2000; for example, taking the transmission mechanism as a conveyor belt, the direction of movement of the side of the conveyor belt used to support the bottle 2000 for transmission is the transmission direction X.

[0090] For example, in some embodiments, the stacking operation of the bottle stacking device 1000 can specifically be:

[0091] In the initial state, the lifting mechanism 200 is located in the area below the support frame 100, that is, the bottle 2000 can be moved into the bottle holding area 213 of the main frame 210 of the lifting mechanism 200 under the transmission operation of the transmission mechanism; the output end of the bottle holding cylinder 231 of the bottle holding mechanism 230 is in the extended state, at which time the bottle holding claw 232 is in the retracted state and fits against the side support 212, and the output end of the bottle pressing cylinder 221 of the bottle pressing mechanism 220 is in the retracted state.

[0092] Multiple bottles 2000 are transferred via a transmission mechanism. When the first bottle 2000 (this example uses the first bottle 2000; in practice, it could be the second, third, or any other bottle) moves into the bottle-holding area 213, the lever switch 400 located upstream of the bottle-holding area 213 in the transmission direction X is activated. The controller receives an electrical signal and controls the bottle stoppers 500 located upstream and downstream of the bottle-holding area 213 in the transmission direction X to extend and prevent the bottle 2000 from continuing to be transferred. Simultaneously, the controller controls the bottle-holding cylinder 231 to retract its output end, causing the bottle-holding claw 232 to rotate into the bottle-holding state. The two bottle-holding claws 232 on the two side supports 212 work together to position and clamp the bottle 2000. Then, the drive mechanism 300 can lift the main frame 210 away from the direction of gravity G. At this time, the bottle gripper 232 moves relative to the bottle body 2000 away from the direction of gravity G until the support member 241 of the bottle support mechanism 240 abuts against the bottom of the bottle body 2100 of the bottle body 2000. At the same time, the output end of the pressure cylinder 221 extends to control the pressure member 222 to abut against the top of the bottle body 2000, so that the bottle body 2000 is clamped between the pressure member 222 and the support member 241, and is radially positioned by the bottle gripper 232. The controller controls the bottle gripper cylinder 231 to retract its output end to drive the bottle gripper 232 to perform the positioning and gripping action of the bottle body 2000, and the action of the support member 241 abutting against the bottom of the bottle body 2100 of the bottle body 2000 to support the bottle. These actions can be performed simultaneously or in steps.

[0093] After the drive mechanism 300 lifts the lifting assembly and the first bottle 2000 it holds to a preset height, the controller can move the bottle stopper 500 located upstream of the bottle holding area 213 in the transmission direction X, so that the transmission mechanism moves the second bottle 2000 below the lifting mechanism 200 and is blocked by the bottle stopper 500 located downstream of the bottle holding area 213 in the transmission direction X. Then, the drive mechanism 300 can lower the lifting assembly and the first bottle 2000 it holds until the first bottle 2000 is stacked on top of the second bottle 2000. At this time, the first bottle 2000 is supported by the second bottle 2000, and the descent stops when the first bottle 2000 is released from the bottle support mechanism 240. Subsequently, the controller controls the bottle-holding cylinder 231 to extend its output end, thereby driving the bottle-holding claw 232 to rotate to a retracted state to cancel the clamping operation on the first bottle 2000 and to avoid the movement of the first bottle 2000 along the transmission direction X; the output end of the bottle-pressing cylinder 221 retracts to control the bottle-pressing component 222 to move away from the first bottle 2000. At this point, the bottle stacking operation is completed.

[0094] Finally, the controller can control the bottle deflectors 500 located upstream and downstream of the bottle holding area 213 in the transmission direction X to retract and move away from the transmission path. The first and second bottles 2000 stacked can continue to be transported forward by the transmission mechanism, while the third bottle 2000 moves between the two bottle deflectors 500 and repeats the above operation to continue stacking bottles.

[0095] Please refer to Figure 9 and Figure 8 In some embodiments, the bottle holding mechanism 230 includes a bottle holding drive 233 and a holding clamp 236. Each side bracket 212 is movably provided with a holding clamp 236. The bottle holding drive 233 drives and connects to the holding clamp 236. The bottle holding drive 233 is configured to drive the holding clamps 236 on both sides to move towards each other or away from each other.

[0096] The bottle-holding drive component 233 can refer to a drive source such as a drive cylinder, drive hydraulic cylinder, or linear guide rod, used to drive the slide rail beam 234 to move along the direction of gravity G. The bottle-holding drive component 233 can be connected to the clamping component directly or indirectly to drive the clamping component.

[0097] Optionally, the bottle-holding drive component 233 can be indirectly connected to the clamping component 236 through a structure such as a linkage, so that the output direction of the bottle-holding drive component 233 is not the same as the moving direction of the clamping component 236; or, the bottle-holding drive component 233 can be directly connected to the clamping component, so that the bottle-holding drive component 233 can drive the clamping component 236 to move along the output direction.

[0098] Clamping component 236 refers to a structural component used to clamp the bottle body 2000. Optionally, clamping component 236 may be, but is not limited to, a block structure, a rod structure, a plate structure, a support structure, etc.

[0099] Each side bracket 212 is movably provided with a clamping member 236; it can be understood that there are at least two clamping members 236, and the clamping members 236 are movably provided on both sides of the side bracket 212, so that the clamping members 236 on both sides can move synchronously and towards each other to form a clamping action.

[0100] Optionally, the clamping member 236 can be hinged to the side bracket 212 via a connecting rod, or the clamping member 236 can be directly hinged to the side bracket 212, or the clamping member 236 can be movably connected to the side bracket 212 via a guide structure such as a guide cylinder, so that the clamping member 236 moves horizontally along the guide cylinder under the driving action of the bottle-holding drive member 233; or, the bottle-holding drive member 233 can be assembled on the side bracket 212, and the clamping member 236 can be directly connected to the output end of the bottle-holding drive member 233, so as to realize the movable assembly of the clamping member 236 and the side bracket 212.

[0101] For example, in some embodiments, the bottle-holding drive member 233 can be a drive cylinder, and the bottle-holding drive member 233 can be mounted on the side bracket 212. The output end of the bottle-holding drive member 233 is arranged in a horizontal direction, and the output end of the bottle-holding drive member 233 is connected to the corresponding clamping member 236. In this way, the clamping members 236 provided on each side bracket 212 can move towards each other under the drive of the bottle-holding drive member 233 to move towards the bottle-holding area 213 and clamp the bottle 2000. Alternatively, the clamping members 236 provided on each side bracket 212 can move away from each other under the drive of the bottle-holding drive member 233 to perform an opening action.

[0102] Please refer to Figure 9 and Figure 8 In some embodiments, the bottle-holding mechanism 230 further includes a slide rail beam 234, a clamping link 235, and a clamping support rod 237; the bottle-holding drive member 233 is disposed on the top support 211, and the opposite ends of the slide rail beam 234 are respectively disposed toward the side supports 212 at both ends. The output end of the bottle-holding drive member 233 is connected to the slide rail beam 234 and is used to drive the slide rail beam 234 to move along the direction of gravity G.

[0103] The bottle-holding drive component 233 is mounted on the top bracket 211. Optionally, the bottle-holding drive component 233 can be fixedly assembled to the top bracket 211 by means of bracket connection, fastener locking connection, etc.

[0104] The output end of the bottle-holding drive unit 233 is connected to the slide rail beam 234, so that the bottle-holding drive unit 233 can drive the slide rail beam 234 to move along the direction of gravity G between the side supports 212 at both ends. The slide rail beam 234 mentioned above refers to a beam structure with a slide rail structure.

[0105] Two clamping sliders 2341 are slidably mounted on the slide rail beam 234; there are two clamping connecting rods 235, which are respectively connected to the corresponding clamping sliders 2341; the clamping support rod 237 is hinged to the side bracket 212, and the clamping support rod 237 is hinged to the clamping connecting rod 235 and the clamping piece 236.

[0106] Two clamping sliders 2341 are slidably mounted on the slide rail beam 234, allowing them to slide along the slide rail beam 234. It should be understood that the opposite ends of the slide rail beam 234 are respectively positioned towards the side supports 212 at both ends, thus the sliding direction of the two clamping sliders 2341 is the same as the arrangement direction of the side supports 212 at both ends.

[0107] There are two clamping links 235, and the two clamping links 235 are respectively connected to the corresponding clamping sliders 2341. In this way, the two clamping sliders 2341 can drive the connected clamping links 235 to slide.

[0108] The clamping support rod 237 refers to the connecting rod structure disposed between the side support 212 and the clamping link 235. The clamping support rod 237 is hinged to the side support 212, and also hinged to the clamping link 235 and the clamping member 236. Thus, when the clamping link 235 is driven by the bottle-holding drive member 233 to move the slide rail beam 234 downwards along the direction of gravity G, the clamping link 235 can drive the clamping support rod 237 to rotate around the hinge point on the side support 212. This allows the clamping link 235 and the clamping member 236 to move towards the bottle-holding area 213 along the sliding direction of the clamping slider 2341 on the slide rail beam 234.

[0109] The clamping support rod 237 is hinged to the clamping connecting rod 235 and the clamping member 236; optionally, the clamping support rod 237 can be hinged to the clamping connecting rod 235 and the clamping member 236 respectively, that is, there is a gap between the hinge point of the clamping support rod 237 and the clamping connecting rod 235 and the hinge point of the clamping support rod 237 and the clamping member 236; or, the clamping support rod 237 can be hinged to the clamping connecting rod 235 and the clamping member 236 at the same location simultaneously.

[0110] Please refer to Figure 9 and Figure 8 In some embodiments, the clamping support rod 237 includes a first connecting part 2371, a second connecting part 2372 and a third connecting part 2373 arranged in sequence. The first connecting part 2371 is hinged to the side bracket 212, the second connecting part 2372 is hinged to the corresponding clamping link 235, and the third connecting part 2373 is hinged to the corresponding clamping member 236.

[0111] The clamping support rod 237 includes a first connecting part 2371, a second connecting part 2372 and a third connecting part 2373 arranged in sequence. It should be understood that the first connecting part 2371, the second connecting part 2372 and the third connecting part 2373 refer to three connection points arranged in sequence on the clamping support rod 237.

[0112] Each clamping link 235 may be connected to a second connecting portion 2372 of one or more clamping support rods 237. Exemplarily, in some embodiments, the clamping link 235 may be connected and assembled with the side bracket 212 at the corresponding end by two clamping support rods 237, and the two clamping support rods 237 are arranged sequentially at intervals along the direction of gravity G.

[0113] The first connecting part 2371 is hinged to the side support 212, the second connecting part 2372 is hinged to the corresponding clamping link 235, and the third connecting part 2373 is hinged to the corresponding clamping member 236. Thus, the clamping support rod 237 can rotate around the first connecting part 2371, so that the second connecting part 2372 and the third connecting part 2373 of the clamping support rod 237 can synchronously drive the clamping link 235 and the clamping member 236 to rotate. In this way, the clamping members 236 at both ends can rotate into the bottle holding area to form a bottle holding operation, or the clamping members 236 at both ends can rotate towards the adjacent side support 212 to open.

[0114] Please refer to Figure 9 and Figure 8 In some embodiments, the two ends of the clamping link 235 are hinged to the second connecting portion 2372 of the clamping support 237, and the third connecting portion 2373 of the clamping support 237 at the two ends of the clamping link 235 are hinged to the clamping member 236.

[0115] In this embodiment, a second connecting portion 2372 of a clamping support rod 237 is hinged to each of the opposite ends of the clamping link 235, that is, two clamping support rods 237 are symmetrically arranged at opposite ends of the clamping link 235. In this way, the clamping link 235 and the side bracket 212 at the corresponding end can be connected and assembled by an even number of clamping support rods 237, such as two, four, or six.

[0116] Meanwhile, the third connecting parts 2373 of the clamping support rods 237 at both ends of the clamping link 235 are all hinged with clamping members 236; that is, each clamping link 235 can be connected to two clamping members 236 through the clamping support rods 237, so that the two clamping links 235 at both ends are provided with four clamping members 236 through the clamping support rods 237. The four clamping members 236 can be used to simultaneously clamp the bottle 2000 in the bottle holding area 213, so as to effectively improve the stability of clamping the bottle 2000; at the same time, the four clamping members 236 also have the advantages of automatic centering and reliable clamping, overcoming the risk that the bottle 2000 is prone to tilting and falling.

[0117] Please refer to Figure 9 and ​ In some embodiments, the side support 212 is provided with a clearance groove 2121, which is used to accommodate the hinge node formed by the second connecting part 2372 and the clamping link 235.

[0118] It should be understood that when the second connecting part 2372 is hinged to the clamping link 235, a hinge node is formed, for example, through a structure that forms a hinged connection via a pivot, pin, etc. When the clamping link 235 moves upward in the direction of gravity G under the drive of the slide rail beam 234, the clamping link 235 will simultaneously drive the second connecting part 2372 to rotate towards the side bracket 212; thus, when the clamping link 235 rotates to fit against the side bracket 212 or rotates to insert into the inner cavity of the side bracket 212, the clearance groove 2121 can provide clearance for the hinge node, so as to facilitate the rotation of the clamping support rod 237.

[0119] For example, in some embodiments, the specific bottle-holding action of the bottle-holding mechanism 230 can be:

[0120] In the initial state, the bottle-holding drive component 233 drives the slide rail beam 234 to move to the position above the direction of gravity G. At this time, the clamping link 235 is set against the side bracket 212 at the corresponding end, and the clamping component 236 is set against the clamping link 235.

[0121] When a bottle 2000 is placed in the bottle holding area 213, the bottle holding drive 233 can be controlled to move the slide rail beam 234 up and down along the direction of gravity G. At this time, the clamping link 235 will move down synchronously with the slide rail beam 234. The clamping link 235 simultaneously applies a downward force in the direction of gravity G to the second connecting part 2372 of the clamping support rod 237, causing the clamping support rod 237 to rotate around its first connecting part 2371. As a result, the second connecting part 2372 of the clamping support rod 237 will move away from the first connecting part 2371 in the horizontal direction during the rotation around the first connecting part 2371, thereby causing the second connecting part 2372 to drive the clamping link 235 to slide along the slide rail beam 234. Similarly, as the third connecting part 2373 of the clamping support rod 237 rotates around the first connecting part 2371, it will move away from the first connecting part 2371 in the horizontal direction, thereby causing the third connecting part 2373 to drive the clamping member 236 to move toward the center of the bottle holding area 213.

[0122] As a result, the clamping parts 236 at both ends can move towards the center of the bottle holding area 213 simultaneously, forming a state of tightly holding the bottle body 2000.

[0123] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
