Description

Technical Field

[0001] The utility model relates to the technical field of cylinder auxiliary gas charging and discharging components, in particular to a gas charging and discharging mechanism. Background Art

[0002] With the rapid development of industry, various types of industrial machinery have emerged one after another, and chain conveyor is one of them. Chain conveyor is a conveyor that uses chains to pull and carry materials, or slats, metal mesh belts and rollers installed on the chain. It can be divided into chain type, chain plate type, chain mesh type and slat type. In the process of setting up an automated production line, multiple clamps are usually installed on the chain plate of the chain plate conveyor to clamp the processing object, and then the processing object is automatically transferred from one machine tool to another, and the machine tool automatically processes, loads and unloads, inspects, etc.; the worker's task is only to adjust, supervise and manage the automatic line, and does not participate in direct operation; all machines and equipment operate at a unified rhythm, and the production process is highly continuous.

[0003] The Chinese patent with the authorization announcement number CN215248007U discloses a vertical ground chain conveyor, comprising: a frame, a lower rotating drum is rotatably arranged at the lower end of the frame through a lower bearing seat, an upper rotating drum is rotatably arranged at the upper end of the frame through an upper bearing seat, a transmission belt is arranged between the lower rotating drum and the upper rotating drum, and a plurality of clamping mechanisms are evenly arranged on the transmission belt; the structure of the clamping mechanism comprises: clamping cylinders are symmetrically arranged on both sides of the transmission belt, and movable cylinders are respectively arranged on the piston rods of the clamping cylinders. A plate, a plurality of sliding holes are evenly arranged on the movable plate, a sliding rod matching with the sliding hole is slidably arranged in the sliding hole, a first limit block is arranged on one end of the sliding rod extending out of the sliding hole close to the edge of the transmission belt, and a second limit block is arranged on the other end of the sliding rod extending out of the sliding hole close to the center of the transmission belt, a return spring is sleeved on the sliding rod between the second limit block and the movable plate, one end of the return spring is abutted against the second limit block, and the other end of the return spring is abutted against the movable plate, and clamping contacts are respectively arranged on the second limit blocks.

[0004] The above-mentioned existing technical solutions have the following defects: since the repeated clamping and loosening of the workpiece by the clamping cylinder needs to be achieved by repeatedly inflating and deflating the clamping cylinder, each clamping cylinder needs to be connected to an air pipe. In the process of the clamping mechanism circulating with the conveyor belt, the air pipes of these clamping mechanisms will be spirally entangled together, causing blockage of the air pipes, thereby affecting the clamping effect of the workpiece, which needs to be improved. Utility Model Content

[0005] The problem to be solved by the utility model is to provide a charging and discharging mechanism for the above-mentioned deficiencies existing in the prior art, which achieves the purpose of facilitating the charging and discharging of pneumatic components on a conveyor.

[0006] The above utility model object of the utility model is achieved through the following technical solutions:

[0007] A gas charging and discharging mechanism is used to cooperate with a conveyor arrangement with multiple pneumatic elements. The gas charging and discharging mechanism includes multiple adapters sequentially arranged on the conveying surface of the conveyor, a pair of transfer channels opened on the adapters, a pressing air valve arranged at the end of the transfer channel, a mounting frame arranged on the frame of the conveyor, a pair of driving members arranged on the mounting frame, a pressing plate arranged at the moving end of the driving member, and a pair of gas channels opened on the pressing plate; the moving paths of these adapters pass under the pressing plate in sequence, and the moving path of the pressing plate passes through the pressing air valve to complete the connection between the gas channel and the transfer channel and the pneumatic element; the two pressing plates are symmetrically arranged, and one of the gas channels on the pressing plate is used to connect to an air compressor.

[0008] By adopting the above technical scheme, during the circulation of the pneumatic components and the adapter seat along the conveying surface of the conveyor, each adapter seat will pass under the pair of pressing plates in turn. At this time, the driving member drives the pressing plate to move close to the adapter seat and presses the pressing head of the pressing valve, so that the gas channel and the adapter channel can be connected, so that the compressed air of the air compressor can be respectively delivered to the A and B ports of the two pneumatic components by one of the gas channels on the two pressing plates, and the B and A ports of the two pneumatic components are discharged through the adapter channel and through the other gas channel on the two pressing plates, thereby continuously completing the operations of inflation clamping, pressure holding clamping, deflation and loosening of the pneumatic components, and the air pipes of the pneumatic components are directly arranged on the conveying surface and connected to the adapter channel, without the need to twist with the conveyor, thereby achieving the purpose of facilitating the inflation and deflation of the pneumatic components (such as cylinders, pneumatic motors, etc.) on the conveyor.

[0009] The utility model is further configured as follows: a pair of slide grooves are respectively arranged close to the pair of driving members on the mounting frame; the bottom end of the adapter protrudes to the outside of the conveying surface of the conveyor and is slidably inserted into the slide grooves.

[0010] By adopting the above technical solution, when the adapter seat passes through the driving member, its protruding bottom end will slide into the slide groove for initial positioning without affecting the sliding of the adapter seat, thereby avoiding the influence of the loose conveying surface of the conveyor on the alignment accuracy of the adapter seat and the pressing plate, thereby ensuring that the gas channel is smoothly connected with the adapter channel and the pneumatic component through the pressing air valve.

[0011] The utility model is further configured as follows: the driving member is configured as a cylinder, a hydraulic cylinder, or a linear motor.

[0012] By adopting the above technical solution, preferably using a cylinder, a suitable pre-pressure can be maintained between the pressing plate and the pressing head of the pressing air valve.

[0013] The utility model is further configured as follows: it also includes a pair of pressing sleeves protruding from the pressing plate and connected to the gas channel, the pressing sleeves are crimped onto the pressing head of the pressing gas valve and connected to the switching channel.

[0014] By adopting the above technical solution, the sealing performance of the gas channel and the transfer channel after they are connected can be ensured.

[0015] The utility model is further configured to include: a pair of guide posts arranged on the pressing plate, and a pair of guide holes opened on the adapter, and the guide posts are slidably inserted into the guide holes.

[0016] By adopting the above technical solution, the alignment accuracy of the pressing sleeve and the pressing air valve can be guaranteed, thereby ensuring that the gas channel is smoothly connected with the switching channel and the pneumatic component through the pressing air valve.

[0017] The utility model is further configured as follows: the bottom surface of the guide column is configured as a guide surface.

[0018] By adopting the above technical solution, the guide surface is used to guide the guide column to slide and be inserted into the guide hole.

[0019] The utility model is further configured as follows: there is a height difference between the top surface of the adapter provided with the guide hole and the top surface provided with the pressing air valve, so that the adapter is in a concave shape.

[0020] By adopting the above technical solution, after the guide column is slidably inserted into the guide hole, the pressing sleeve will be crimped onto the pressing head of the pressing air valve, which can ensure the alignment accuracy of the pressing sleeve and the pressing air valve, and further ensure that the gas channel is smoothly connected with the transfer channel and the pneumatic component through the pressing air valve.

[0021] The utility model is further configured to include: a position switch electrically connected to the pair of driving members, wherein the position switch is installed on the mounting frame in a manner that the detection end faces the adapter seat.

[0022] By adopting the above technical solution, when every two adapter seats pass through the position switch, the adapter channel that needs to be inflated and deflated passes under the pair of pressing plates at the same time. At this time, the position switch will control the drive part to start based on the detection signal to complete the inflation clamping and deflation release operations of the moving element.

[0023] The utility model is further configured as follows: the position switch is configured as a travel switch or a proximity switch.

[0024] By adopting the above technical solution, a proximity switch is preferably used and arranged between the pair of driving members.

[0025] The utility model is further configured as follows: it also includes a dust cover arranged on the mounting frame, and the dust cover is arranged on the pressing air valve and the pressing plate.

[0027] To sum up, the beneficial technical effect of the utility model is as follows: by setting two pairs of gas channels connected to each group of transfer channels and pneumatic components in sequence, and assisted by pressing the air valve to control the inflation and deflation process, the inflation clamping, pressure holding clamping, deflation and loosening of the pneumatic components can be completed continuously. The air pipes of the pneumatic components are directly arranged on the conveying surface and connected to the transfer channels, and there is no need to twist with the conveyor, thereby achieving the purpose of facilitating the inflation and deflation of pneumatic components (such as cylinders, pneumatic motors, etc.) on the conveyor.

[0033] In order to make the technical means, creative features, objectives and functions achieved by the present invention clearer and easier to understand, the present invention is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0034] Reference Figure 1 , is an air charging and discharging mechanism disclosed in the utility model, which is used to cooperate with a conveyor 1 with multiple pneumatic elements 2, and these pneumatic elements 2 are arranged at intervals along the conveying surface of the conveyor 1; the air charging and discharging mechanism includes multiple dual-channel adapter components 3 arranged at intervals along the conveying surface of the conveyor 1 and arranged one-to-one with the pneumatic elements 2, a mounting frame 4 arranged on the frame of the conveyor 1, a pair of driving members 5 (cylinders) and dust covers 6 arranged on the mounting frame 4, a dual-channel pressing component 7 arranged at the moving end of the driving member 5, and a position switch 8 (proximity switch) electrically connected to the pair of driving members 5. Among them, one end opening of the dual-channel adapter assembly 3 is respectively connected to the A and B ports of the pneumatic element 2, and the other end opening passes through the bottom of the dual-channel pressing assembly 7 in sequence. The dual-channel pressing assembly 7 is driven to rise and fall by the driving member 5, and completes the charging and deflating of the pneumatic element 2 through valve control. The position switch 8 is installed on the mounting frame 4 in a manner that the detection end faces the dual-channel adapter assembly 3, and the dust cover 6 is provided on the dual-channel adapter assembly 3 and the dual-channel pressing assembly 7.

The dual-channel pressing assembly 7 includes a pressing plate 71 arranged at the moving end of the driving member 5, a pair of gas channels 72 opened on the pressing plate 71, a pair of pressing sleeves 73 protruding from the pressing plate 71 and connected to the gas channels 72, a pair of guide posts 74 arranged on the pressing plate 71, and a guide surface 75 arranged on the bottom surface of the guide post 74.

[0036] The pressing sleeve 73 is crimped onto the pressing head of the pressing air valve 33 and connected to the transfer channel 32. There is a drop between the top surface of the transfer seat 31 provided with the guide hole 34 and the top surface provided with the pressing air valve 33, so that the transfer seat 31 is in a concave shape. After the guide post 74 is slidably inserted into the guide hole 34, the pressing sleeve 73 is crimped onto the pressing head of the pressing air valve 33, which can ensure the alignment accuracy of the pressing sleeve 73 and the pressing air valve 33, and further ensure the sealing of the gas channel 72 and the transfer channel 32 after the connection, and ensure that the gas channel 72 is smoothly connected with the transfer channel 32 and the pneumatic element 2 through the pressing air valve 33.
