Abstract
Description
Technical Field
[0001] The invention relates to the technical field of pneumatic control, in particular to a multifunctional fast-acting circuit and a starting device. Background Art
[0002] Pneumatic transmission has the advantages of no pollution, simple structure, low maintenance cost and convenient gas source, so it has been widely used in light-load manipulators or automation equipment. Nowadays, with the rapid development of the automation industry, people are no longer satisfied with "safety" and "efficiency" production, but also pay more and more attention to "cost", "energy saving" and "environmental protection". However, some pneumatic devices currently have the following disadvantages: 1. When the air is suddenly cut off, the cylinder will fall under the influence of the deadweight of the clamped workpiece, causing a safety accident. In this case, an anti-fall cylinder is generally used to deal with it, which will lead to a complex structure and increased costs; 2. During the movement of the cylinder, the air in the cavity is eventually discharged into the atmosphere, which results in a large amount of compressed air consumption, which not only increases the cost of use, but also causes energy waste; 3. When a robot needs to grab different parts: when grabbing parts with high strength and not easy to be damaged, high speed is used to ensure efficiency; when grabbing parts that are fragile and easy to deform, low speed is used to ensure quality. In the face of this situation, the general pneumatic device is to manually adjust the throttle valve at the inlet and outlet of the cylinder, resulting in low efficiency. Summary of the invention

[0006] As a further technical solution, the exhaust circuit also includes a first throttle valve disposed between the first air-controlled one-way valve and the third one-control solenoid valve, for controlling the size of the airflow.
[0007] As a further technical solution, the exhaust circuit further includes a second throttle valve and a second air-controlled one-way valve, wherein the air inlet and the air outlet of the second throttle valve are respectively connected to an air outlet of the third one-way control valve and an air inlet of the second air-controlled one-way valve; The air control port of the second air-controlled one-way valve is connected to the rodless cavity, and is used to transport the airflow in the rod cavity to the rodless cavity; the air outlet of the second air-controlled one-way valve is connected to the double-control solenoid valve, so that the airflow in the rodless cavity is discharged after passing through the first one-control solenoid valve, the third one-control solenoid valve, the second throttle valve, the second air-controlled one-way valve, and the double-control solenoid valve in sequence.

[0009] As a further technical solution, when the double-control solenoid valve is switched to the second working position, the air inlet P1 of the double-control solenoid valve is connected to its air outlet S1, and the air inlet A of the double-control solenoid valve is connected to the air outlet of the second air-controlled one-way valve, so that the gas from the pressure regulating valve is discharged through the air outlet S1 of the double-control solenoid valve, the one-way valve, the actuator, the first one-control solenoid valve, the third one-control solenoid valve, the second throttle valve, the second air-controlled one-way valve, and the air outlet R1 of the double-control solenoid valve.

Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in the present application.
[0020] Example 1 This embodiment provides a multifunctional fast action circuit to solve the problems of the actuator (such as a cylinder) falling under the influence of its own weight when the air is suddenly cut off during operation, which eventually causes a safety accident, and the problems of large amount of compressed air consumption, increased cost, and waste of resources. Figure 1-Figure 4 , specifically including a pressure regulating valve 1, a double-control solenoid valve 2, a first single-control solenoid valve 3, an actuator 4, a one-way valve 5, and an exhaust circuit; The air inlet and air outlet of the pressure regulating valve 1 are respectively connected to the air outlet of the air source 6 and an air inlet of the double-control solenoid valve 2. The double-control solenoid valve 2 is connected to the rodless cavity of the actuator 4 through the first single-control solenoid valve 3. The double-control solenoid valve 2 is connected to the rod cavity of the actuator 4 through the one-way valve 5. One end of the exhaust circuit is connected to the rod chamber of the actuator 4, and the other end is divided into two branches. One branch is connected to the rodless chamber of the actuator 4, and is used to transport the airflow in the rod chamber to the rodless chamber. The other branch is connected to the double-control solenoid valve 2, and is used to discharge the airflow in the rodless chamber through the double-control solenoid valve 2.
[0021] For example, when the cylinder is extended, one coil of the double-control solenoid valve 2 is conductive, the valve core moves, and the first single-control solenoid valve 3 for controlling the intake and exhaust of the rodless chamber of the cylinder is conductive, the valve core moves, and the intake circuit is turned on; when the exhaust circuit is turned on, the cylinder can be extended; For example, the gas source 6 is compressed air. The pressure regulating valve 1 is a filter pressure regulating valve 1, which filters impurities in the gas source 6 and transports them to the cylinder.
[0022] In the specific implementation process, the exhaust circuit includes a second one-way solenoid valve 7, a third one-way solenoid valve 8, and a first air-controlled one-way valve 9 which are connected in series in sequence. The air outlet of the second one-way solenoid valve 7 is connected to the air inlet of the third one-way solenoid valve 8. The air inlet of the second one-way solenoid valve 7 is provided with two branches, one branch is connected to the rod chamber of the actuator 4, and the other branch is connected to the air inlet of the one-way valve 5. The air control port of the first air-controlled one-way valve 9 is connected to the rodless cavity, which is used to transport the airflow in the rod cavity to the rodless cavity, so as to reduce the waste of compressed air and achieve the purpose of energy saving. At the same time, the compressed air of the air source 6 and the compressed air of the rod cavity enter the rodless cavity at the same time, which increases the flow rate and makes the cylinder move faster; the air outlet of the first air-controlled one-way valve 9 is connected to the double-control solenoid valve 2, so that the airflow in the rodless cavity is discharged after passing through the first one-control solenoid valve 3, the third one-control solenoid valve 8, the first air-controlled one-way valve 9, and the double-control solenoid valve 2 in sequence. That is, when the cylinder retracts, the air source 6 enters the rod cavity of the cylinder through the pressure regulating valve 1 and the double-control solenoid valve 2 in sequence, and then passes through the rodless cavity of the cylinder, the first one-control solenoid valve 3, the third one-control solenoid valve 8, the first air-controlled one-way valve 9, and the double-control solenoid valve 2 and is discharged to realize rapid retraction of the cylinder.
[0023] In the specific implementation process, the exhaust circuit also includes a first throttle valve 10 arranged between the first air-controlled one-way valve 9 and the third one-way solenoid valve 8, which is used to control the airflow size, that is, the air inlet and the air outlet of the first throttle valve 10 are respectively connected to an outlet of the third one-way solenoid valve 8 and the air inlet of the first air-controlled one-way valve 9, and the opening of the first throttle valve 10 can be controlled to control the gas flow on the branch.
[0024] Furthermore, in order to automatically switch to suit different workpieces, the exhaust circuit also includes a second throttle valve 11 and a second air-controlled one-way valve 12. The air inlet and the air outlet of the second throttle valve 11 are respectively connected to an air outlet of the third one-way solenoid valve 8 and an air inlet of the second air-controlled one-way valve 12; the air control port of the second air-controlled one-way valve 12 is connected to the rodless cavity, which is used to transport the airflow in the rod cavity to the rodless cavity; the air outlet of the second air-controlled one-way valve 12 is connected to the double-control solenoid valve 2, so that the airflow in the rodless cavity is discharged after passing through the first one-control solenoid valve 3, the third one-control solenoid valve 8, the second throttle valve 11, the second air-controlled one-way valve 12, and the double-control solenoid valve 2 in sequence. That is, the needs of different workpieces can be met by selecting to open the first air-controlled one-way valve 9 or the second air-controlled one-way valve 12; For example, when the cylinder is extended, the second air-controlled one-way valve 12 can be opened to transport the gas in the rod chamber of the cylinder to the rodless chamber of the cylinder through the second air-controlled one-way valve 12. While saving the gas source 6, the gas volume in the rodless chamber is increased, thereby increasing the movement speed of the cylinder; and by selecting the branch where the first throttle valve 10 or the second throttle valve 11 is located, the air flow speed can be adjusted.
[0025] When the cylinder retracts, the gas in the rodless chamber is discharged through the first single-control solenoid valve 3, the third single-control solenoid valve 8, the second air-controlled one-way valve 12 to the double-control solenoid valve 2. At this time, the route for air intake into the rodless chamber is the same as the route for exhausting the rodless chamber. It can be explained that the same route here refers to: the third single-control solenoid valve 8, the first throttle valve 10, the first air-controlled one-way valve 9 or the third single-control solenoid valve 8, the second throttle valve 11, the second air-controlled one-way valve 12.
[0026] In the specific implementation process, the double-control solenoid valve 2 is a two-position five-way solenoid valve. When the double-control solenoid valve 2 is switched to the first working position, the solenoid valve core moves, and the air inlet P of the double-control solenoid valve 2 is connected to its air outlet R, and the air outlet R is connected to the first air inlet of the first single-control solenoid valve 3, and the gas in the rod chamber is discharged into the rodless chamber through the exhaust circuit. At this time, the air inlet P of the double-control solenoid valve 2 is not connected to the air outlet S on the same side thereof, that is, after the air source 6 enters the double-control solenoid valve 2 from the pressure regulating valve 1, the air inlet P is connected to the air outlet R, the coil of the first single-control solenoid valve 3 is energized and the valve core moves, that is, the air inlet circuit is connected, and the compressed gas enters the rodless chamber of the cylinder. At the same time, the coil of the second single-control solenoid valve 7 is energized and is in a conducting state, and there is air in the air control port of the first air-controlled one-way valve 9 or the second air-controlled one-way valve 12 (that is, the first air-controlled one-way valve 9 or the second air-controlled one-way valve 12 is connected), so that the exhaust circuit of the rod chamber of the cylinder is connected, then, the compressed air flows from the rod chamber of the cylinder through the second single-control solenoid valve 7, the third single-control solenoid valve 8, the first air-controlled one-way valve 9 or the second air-controlled one-way valve 12 to the rodless chamber of the cylinder, so as to complete the action of extending the cylinder (see Figure 1 , Figure 2 ), the air intake of the rodless chamber of the cylinder is increased. Therefore, the cylinder in the fast action circuit protected by the present invention can be extended more quickly, while saving the amount of compressed air, thereby achieving the purpose of energy saving.
[0027] When the double-control solenoid valve 2 is switched to the second working position, the solenoid valve core moves and switches, the air inlet P1 of the double-control solenoid valve 2 is connected to its air outlet S1, and the air inlet A of the double-control solenoid valve 2 is connected to an air outlet of the second air-controlled one-way valve 12, so that the gas from the pressure regulating valve 1 passes through the air outlet S1 of the double-control solenoid valve 2, the one-way valve 5, the actuator 4, the first one-control solenoid valve 3, the third one-control solenoid valve 8, the second throttle valve 11, and the second air-controlled one-way valve 1 2. The air is discharged from the outlet R1 of the double-control solenoid valve 2. At this time, the coil of the second single-control solenoid valve 7 is powered off and its valve core is reset, so that the air path is closed; the first single-control solenoid valve 3 is powered off and the valve core is reset, so that the gas in the rodless chamber of the cylinder is discharged through the first single-control solenoid valve 3, the third single-control solenoid valve 8, the first throttle valve 10 (or the second throttle valve 11), the first air-controlled check valve 9 (or the second air-controlled check valve 12), and the air inlet A of the double-control solenoid valve 2, so as to complete the action of retracting the cylinder (see Figure 3 , Figure 4 ), the design of this embodiment allows the rod chamber and the rodless chamber of the cylinder to share an exhaust circuit, reducing the number of required pneumatic components and making the structure simpler.
[0028] When the air in the cylinder is cut off during movement, there is no air in the air control ports of the first air-controlled one-way valve 9 and the second air-controlled one-way valve 12. At this time, the first air-controlled one-way valve 9 and the second air-controlled one-way valve 12 are closed, and the gas cannot be discharged from the rod chamber of the cylinder, so that the cylinder remains in the current state and stops, and then the workpiece can be kept in the original position when the air is cut off, avoiding the workpiece from falling under its own weight when the air is suddenly cut off and causing a safety accident.
[0029] When performing multi-stage speed regulation of the cylinder, according to the design of the first throttle valve 10 and the second throttle valve 11 in the exhaust circuit, the opening of the corresponding throttle valve can be regulated according to the parts to be clamped and then adjusted to a suitable flow rate. When speed regulation is required, the exhaust route of the cylinder can be switched by adjusting the position of the valve core of the third single-control solenoid valve 8 (that is, connected to the first throttle valve 10 or the second throttle valve 11) to achieve the purpose of speed regulation.
[0030] In a specific implementation process, the exhaust port B of the dual-control solenoid valve 2 is connected to the muffler 13 , that is, during the operation of retracting the cylinder, the gas in the rodless chamber is discharged through the muffler 13 .
[0031] Example 2 This embodiment provides a pneumatic device, which includes the multifunctional fast-acting circuit described in Example 1.
