Description

Technical Field

[0001] This utility model relates to the field of automation equipment technology, and in particular to an air circuit structure for preventing falling objects that are subject to lifting and lowering. Background Technology

[0002] With the increasing automation and integration of the domestic sheet metal industry, laser cutting machines, combined with automatic sheet metal loading and unloading mechanisms, are becoming increasingly common in production. Currently, most sheet metal loading and unloading mechanisms in the domestic industry use gears, racks, and lifting cylinders to achieve vertical mechanical movement. These mechanisms often bear heavy loads, and in the event of power outages or gas supply failures during lifting, the Z-axis mechanism risks falling, hindering the lifting of items. Therefore, we propose a pneumatic structure to prevent objects from falling during lifting operations. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a pneumatic structure for preventing objects from falling during lifting and lowering. This utility model solves the problem that in the domestic sheet metal industry, most Z-axis lifting devices for loading and unloading mechanisms use gears, racks, and lifting cylinders to achieve vertical mechanical movement. These mechanisms are often heavily loaded, and in the event of power outages, gas outages, or other emergencies during lifting and lowering, the Z-axis mechanism is at risk of falling, which is detrimental to the lifting and lowering of items.

[0004] This utility model discloses an air circuit structure for preventing falling objects during lifting and lowering, comprising a support frame. Two first three-way connectors are fixedly installed on one side of the upper part of the support frame. One end of each first three-way connector is connected to a first air pipe connector. A safety valve is provided above the first three-way connector. The side of the first three-way connector away from the first air pipe connector is connected to an induction check valve. The side of the induction check valve away from the first three-way connector is connected to a second air pipe connector. A solenoid valve is provided between the two first three-way connectors on the support frame. The end of the solenoid valve near the induction check valve is connected to a first air pipe. The end of the first air pipe away from the induction check valve is connected to a second three-way connector. Both ends of the second three-way connector are connected to a second air pipe connector via a second air pipe.

[0005] In the above scheme, a third air pipe connector is provided above the induced check valve, and the third air pipe connector is connected to the air storage tank connecting pipe.

[0006] In the above scheme, the first air pipe connector is connected to the Z-axis cylinder connecting pipe.

[0007] In the above scheme, the end of the solenoid valve away from the first air pipe is connected to the air source connection pipe.

[0008] In the above scheme, the support frame has two mounting holes on both sides.

[0009] The advantages and beneficial effects of this utility model are as follows:

[0010] 1. A pneumatic structure for preventing falling objects in lifting and lowering motion, used to prevent the Z-axis from falling rapidly when the loading and unloading system loses power or air supply, without affecting the normal operation of the loading and unloading system, and can meet the requirements for preventing falling under abnormal loading and unloading conditions.

[0016] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0017] like Figure 1As shown, this utility model is a pneumatic structure for preventing the fall of objects in a lifting motion. It includes a support frame 1, with two first three-way connectors 2 fixedly installed on one side of the upper part of the support frame 1. One end of each first three-way connector 2 is connected to a first air pipe connector 3. A safety valve 4 is provided above each first three-way connector 2. When the pressure in the pneumatic system exceeds a set pressure, the safety valve 4 releases pressure, thereby ensuring the safe operation of the components. The side of the first three-way connector 2 away from the first air pipe connector 3 is connected to an induction check valve 5, which controls the gas flow in the pneumatic system. The direction of movement of the induced check valve 5 is such that the side away from the first three-way connector 2 is connected to the second air pipe connector 6. The support frame 1 is provided with a solenoid valve 9 between the two first three-way connectors 2. The solenoid valve 9 controls the opening and closing of the air passage, thereby controlling whether air is supplied to the control port of the induced check valve 5. The end of the solenoid valve 9 near the induced check valve 5 is connected to the first air pipe 10. The end of the first air pipe 10 away from the induced check valve 5 is connected to the second three-way connector 11. Both ends of the second three-way connector 11 are connected to the second air pipe connector 6 through the second air pipe 7.

[0018] The induced check valve 5 is provided with a third air pipe connector 12, which is connected to the gas storage tank connecting pipe 13. The gas storage tank connecting pipe 13 can be connected to an external gas storage tank.

[0019] The first air pipe connector 3 is connected to the Z-axis cylinder connecting pipe 14, and the Z-axis cylinder connecting pipe 14 can be connected to the lower chamber of the Z-axis balance cylinder.

[0020] The end of the solenoid valve 9 furthest from the first air pipe 10 is connected to the air source connection pipe 15, which can be connected to an air supply source.

[0021] The support frame 1 has two mounting holes 8 on both sides, through which the air passage structure can be installed.

[0022] Specifically, in this utility model, the Z-axis cylinder connecting pipe 14 is connected to the lower chamber of the Z-axis balance cylinder, the air tank connecting pipe 13 is connected to the air tank, and the air source connecting pipe 15 is connected to the air source for continuous air intake. During normal operation, when the Z-axis rises, the compressed air in the air tank passes through the air tank connecting pipe 13, the induction check valve 5, and the first three-way connector 2 to the Z-axis cylinder connecting pipe 14 and enters the lower chamber of the cylinder. The cylinder rod extends, completing the rising action. When the Z-axis descends, the compressed gas in the lower chamber of the cylinder passes through the Z-axis cylinder connecting pipe 14 and the first three-way connector 2 to the induction check valve 5. The solenoid valve 9 is in the conducting state, and the gas in the air tank connecting pipe 13 enters the induction check valve 5 through the solenoid valve 9, causing the induction check valve 5 to reverse conduction. The Z-axis cylinder connecting pipe 14 and the air tank connecting pipe 13 are connected, and the compressed gas in the cylinder is discharged into the air tank, thus realizing the descending action of the cylinder. When the system experiences a power outage or gas outage, the coil of solenoid valve 9 loses power and solenoid valve 9 is in the closed state. The induced check valve 5 can only achieve unidirectional flow. The Z-axis cylinder connecting pipe 14 and the gas tank connecting pipe 13 are not connected. The gas in the lower chamber of the cylinder is in a closed and pressure-maintaining state. Due to gravity, the Z-axis descends, and the pressure in the lower chamber of the cylinder increases. When the gas pressure reaches the set pressure, the safety valve 4 works to release the gas, and the Z-axis slowly descends to prevent the Z-axis from falling.

[0023] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
