[0034] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and do not necessarily need to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present invention described here can be implemented in an order other than those illustrated or described here. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, device, product or equipment comprising a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or equipment.

[0035] In an embodiment of the present invention, a valve conveying device is provided, as Figures 1 to 4 shown, which includes a track base 1, a guide rail 2 provided on the track base 1, a plurality of sequentially connected carrier mechanisms provided on the guide rail 2, a driving mechanism 6 for driving the carrier mechanism to perform a circular motion along the guide rail 2, and a placing mechanism for placing the valve 4. The plurality of sequentially connected carrier mechanisms means that the head end of one carrier mechanism is connected to the tail end of an adjacent another carrier mechanism. The track base 1 is a base for track installation, which is welded and processed from profiles and steel plates, providing a foundation for track laying.

[0036] The guide rail 2 is a circular closed-loop structure, see Figure 2 and Figure 3 , which can increase the number of carrier mechanisms per unit area, and thus increase the number of transported valves, greatly improving the transportation efficiency. The guide rail 2 is a snake-shaped, wavy, circular, square or elliptical structure, preferably a snake-shaped structure, which includes a plurality of arc segments. The cross-section of the guide rail 2 is preferably a rhombus, with a simple structure and simple manufacturing. The guide rail is the running track of the carrier mechanism, an institution established to enable the carrier mechanism to move orderly.

[0037] The specific structure of the carrier mechanism 3 is as follows: see Figure 5 and Figure 6Each carrier mechanism 3 includes a base 31, a plurality of rollers 32 disposed under the base 31 and capable of moving along the guide rail 2, a suspension mechanism disposed on the base 31, and a connection assembly disposed on the side of the base 31 and connected thereto, wherein the base 31 is provided with a resisting member 33 extending toward the outside of the guide rail 2 (i.e., away from the inside of the guide rail 2, such as toward the drive mechanism 6), and the bottom of the connection assembly is provided with at least one roller 32 capable of moving along the guide rail 2, and the roller 32 can run along the arc section of the guide rail. The resisting member 33 is a nut or a pin, and is used to resist the drive mechanism 6.

[0038] The specific structure of the suspension mechanism is as follows: Figure 11 The suspension mechanism includes a suspension member 37 disposed on the base 31 for placing the valve 4. The suspension member 37 includes a horizontal rod and a clamping member disposed on the rod and matched with the inner groove of the valve. The clamping member is preferably a hook. The valve has an opening, and it only needs to be lowered with the opening facing the suspension member. One valve is placed on one suspension member 37. During transportation, the clamping member cooperates with the inner groove of the valve, and the valve will not move along the axial direction of the suspension member 37, and the valve will not separate from the suspension member 37. Even if the valve moves circumferentially along the suspension member 37, it will not separate from the suspension member, thereby better protecting the valve. The clamping member of the suspension member 37 can be adjusted for different valves, so that the valve does not separate from the suspension member 37 during transportation, so as to transport different valves.

[0039] The specific structure of the driving mechanism 6 is as follows: Figures 7 to 10 The driving mechanism 6 includes a screw 61 that can rotate around its own axis. The outer circumferential surface of the screw 61 is provided with a plurality of recessed portions that are arranged at intervals and cooperate with the abutment member 33 of the carrier mechanism 3. The screw 61 rotates to drive the carrier mechanism to move to a designated position along the guide rail 2, so that the valve 4 on the placement mechanism is transferred to the suspension mechanism on the carrier mechanism. The driving mode of the screw 61 is electric, pneumatic or hydraulic. The carrier mechanism runs along the guide rail under the drive of the driving mechanism and stops at a designated position to facilitate loading or unloading at the designated position. The loading position or unloading position is selected according to the demand (the principle of greatly improving convenience and transportation efficiency), which has great flexibility.

[0040] Loading means transferring the valve on the placing mechanism to the hanging mechanism on the carrier mechanism, and taking the valve away at the unloading position. Unloading means transferring the valve on the hanging mechanism on the carrier mechanism to a specific position.

[0041] The screw has an external thread, and a concave portion is formed by maintaining a distance between two adjacent teeth on the thread. When the carrier is close to the screw, the abutment of the carrier will be stuck in the concave portion, and the screw can be rotated to drive the carrier to move along the track. During the transportation process, there is always a carrier that is in conflict with the screw, and multiple carriers are connected to form a whole. The screw rotates to drive the carrier that is in conflict with it to move along the guide rail 2, so that the carrier as a whole can move along the track.

[0042] The specific structure of the driving mechanism 6 is as follows: the driving mechanism 6 also includes a motor 62, a worm gear reducer and two pulleys 64, one pulley 64 is sleeved on the end of the worm 65 of the worm gear reducer, and the other pulley 64 is sleeved on one end of the screw 61. The two pulleys 64 are connected by a belt. The motor 62 drives the worm gear reducer to drive the belt to move, and the belt movement drives the screw 61 to rotate, thereby driving the transport mechanism to move along the guide rail 2. A gear 63 is sleeved on the end of the worm, and a transmission component (at Figure 9 The transmission components (not shown in the figure, such as bevel gears) are used to change the transmission direction of the torque. The pulley 64 and the belt are set to adjust the rotation speed. For example, one pulley 64 is a large gear and the other pulley 64 is a small gear, and the diameter of the tooth top circle of the large gear is larger than the diameter of the tooth top circle of the small gear. At the same time, the motor 62 and the worm gear reducer can be connected to transmit force.

[0043] The driving mechanism is not only simple in structure, but also ensures that the instantaneous speed of the moving carrier is constant, and the carrier moves smoothly, so that the valve on the carrier moves smoothly, preventing the valve from being damaged or detached from the suspension part due to the fast moving speed, thereby better protecting the valve.

[0044] The specific structure of the connection assembly is as follows: the connection assembly includes a first connection plate 34 and a second connection plate 35 arranged in a straight line, and a third connection plate 36 arranged therebetween and used to connect the first connection plate 34 and the second connection plate 35. The extension direction of the third connection plate 36 is different from the extension direction of the first connection plate 34 and the extension direction of the second connection plate 35. At least one roller 32 capable of moving along the track is arranged at the bottom of the third connection plate 36. The third connection plate 36 is connected to the first connection plate 34 and the second connection plate 35 by a connection pin 38, and the connection is fastened and convenient for unloading and installation.

[0045] The base 31 is preferably provided with four rollers, the center line of the four rollers is a quadrilateral, wherein two rollers (arranged along the Y axis) and the other two rollers (arranged along the Y axis) are respectively located on both sides of the center line of the base. The bottom of the third connecting plate 36 is preferably provided with two rollers, which are arranged along the Y axis, so that the carrying mechanism moves smoothly.

[0046] The valve conveying device further includes a transfer mechanism for transferring the valve 4 on the placement mechanism to the hanging mechanism located at a specified position. The transfer mechanism is arranged on one side of the placement mechanism. The transfer mechanism includes a fixed seat and a manipulator arranged on the fixed seat. The manipulator can stretch and can grasp and release the valve 4.

[0047] The placement mechanism is used for placing the valve 4. The placement mechanism has various structural forms, such as a placement table or a placement rack, and its structure is not limited.

[0048] Furthermore, the valve conveying device further includes a protective net 5 arranged outside the edge of the guide rail. The protective net 5 is a mesh structure and has a certain elasticity, playing a role in protecting safety and preventing the valve from falling.

[0049] In an embodiment provided by the present invention, there are two guide rails, and two screw rods are provided. The two screw rods respectively correspond to the two guide rails one by one. The driving mechanism drives the two screw rods to rotate simultaneously (the rotation directions of the two screw rods are the same), and then drives the two carrier mechanisms to move along the corresponding guide rails. The track base is vertically arranged (i.e., perpendicular to the ground and arranged along the Y-axis), so the guide rails are vertically arranged. The track base has a vertical wall, and the two guide rails are respectively located on the front and back sides of the vertical wall, which can effectively save space in the Y-axis direction and increase the transportation quantity of the carrier mechanism in a limited space; make full use of the warehouse space and improve production efficiency.

[0050] The valve conveying device provided by the present invention is arranged at the warehousing end of the valve to realize the single-piece placement of the valve, so as to realize the full automation of valve processing. Realize the placement and movement of single-piece valves, and can input and output at a specified position, providing a front-end basis for realizing automated logistics. The valve conveying device provided by the present invention can transport different valves, has versatility, and greatly saves warehouse space.

[0051] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
