[0012] The present invention has prominent substantive features and significant progress compared with the prior art. Specifically, the present invention can push the cylinder from the cylinder bracket to the shelf and take the cylinder from the shelf to the cylinder bracket, that is, it has the function of cylinder access:

[0013] (1) When storing the cylinder on the left - hand shelf:

[0014] The gas cylinders are pre-placed on respective gas cylinder brackets, with the bottoms of the gas cylinders on the right side, the sucking mechanism at the right extreme position, the test piece in contact with the right limit switch sensor. The servo control system controls the energization and magnetization of the circular electromagnetic chuck on the left side. The circular electromagnetic chuck on the left side sucks tightly the bottom of the gas cylinder. The bottom of the gas cylinder presses against the block on the left side, and the guide rod on the left side moves relatively to the guide sleeve on the left side to the right, aligning the left end of the guide rod on the left side with the left side surface of the circular electromagnetic chuck on the left side. The block on the left side compresses the pressing spring on the left side, and the right end of the guide rod on the left side presses against the trigger piece on the left side, causing the trigger piece on the left side to rotate to the right and press tightly against the sensor probe on the left side. The sensor probe on the left side transmits the pressure signal to the contact travel switch on the front side. The contact travel switch on the front side sends a signal to the servo control system, indicating that the gas cylinder sensor on the left side senses the gas cylinder. Then, the stacker moves under the control of the servo control system and transports the gas cylinder to the target storage location on the left shelf. The leftmost gas cylinder bracket is aligned horizontally with the right end of the target storage location. Then, the servo control system controls the servo motor to start. The servo motor drives the nut pair to move to the left through the lead screw. The nut pair then drives the rectangular box seat to move to the left to the left extreme position through the double-ear plate support. The circular electromagnetic chuck on the left side then pushes the gas cylinder into the target storage location on the left shelf. The test piece moves to the left limit switch sensor and comes into contact with the left limit switch sensor. The servo control system receives the signal from the left limit switch sensor and controls the servo motor to stop. At the same time, it controls the circular electromagnetic chuck on the left side to de-energize and demagnetize to release the gas cylinder. Then, the servo control system controls the servo motor to start. The servo motor drives the nut pair to move in the reverse direction to the origin position through the lead screw, moving the rectangular box seat to the origin position. The test piece moves to the origin switch sensor and comes into contact with the origin switch sensor. The servo control system receives the signal from the origin switch sensor and controls the servo motor to stop, completing the operation of storing the gas cylinder on the left shelf;

[0015] When storing gas cylinders on the right shelf, the working principle is the same as that for storing gas cylinders on the left shelf:

[0016] The cylinder is pre-placed on each cylinder bracket, with the bottom of the cylinder on the left and the sucking mechanism at the left extreme position. The test piece contacts the left limit switch sensor. The servo control system controls the energization and magnetization of the circular electromagnetic chuck on the right. The circular electromagnetic chuck on the right sucks the bottom of the cylinder. The bottom of the cylinder presses against the block on the right, and the guide rod on the right moves leftward relative to the guide sleeve on the right, aligning the right end of the guide rod on the right with the right side face of the circular electromagnetic chuck on the right. The block on the right compresses the top pressure spring on the right, and the left end of the guide rod on the right presses against the trigger piece on the right, causing the trigger piece on the right to rotate leftward and tightly press against the sensor probe on the right. The sensor probe on the right transmits the pressure signal to the contact travel switch at the rear. The contact travel switch at the rear sends a signal to the servo control system, indicating that the cylinder sensor on the right senses the cylinder. Then, the stacker moves under the control of the servo control system and transports the cylinder to the target storage location on the right shelf. The rightmost cylinder bracket is aligned left and right with the left end of the target storage location. Then, the servo control system controls the servo motor to start. The servo motor drives the nut pair to move rightward through the lead screw. The nut pair then drives the rectangular box seat to move rightward to the right extreme position through the double-ear plate support. The circular electromagnetic chuck on the right then pushes the cylinder into the target storage location on the right shelf. The test piece moves to the right limit switch sensor and contacts it. The servo control system receives the signal from the right limit switch sensor and controls the servo motor to stop. At the same time, it controls the circular electromagnetic chuck on the right to de-energize and demagnetize to release the cylinder. Then, the servo control system controls the servo motor to start. The servo motor drives the nut pair to move reversely to the origin position through the lead screw, moving the rectangular box seat to the origin position. The test piece moves to the origin switch sensor and contacts it. The servo control system receives the signal from the origin switch sensor and controls the servo motor to stop, completing the work of storing the cylinder on the right shelf.

[0017] (2) When taking a cylinder from the left shelf:

[0018] Under the control of the servo control system, the stacker moves to the target storage location on the left shelf. The leftmost cylinder bracket is aligned with the right end of the target storage location horizontally. The servo control system controls the energization and magnetization of the circular electromagnetic chuck on the left side. At the same time, it controls the start of the servo motor. The servo motor drives the rectangular box seat to move from the origin position to the left limit position through the lead screw and nut pair. The test piece moves to the left limit switch sensor and contacts it. The servo control system receives the signal from the left limit switch sensor and controls the servo motor to stop. The circular electromagnetic chuck on the left side tightly holds the bottom of the cylinder. The bottom of the cylinder presses against the left block. The left guide rod moves relatively to the left guide sleeve to the right, aligning the left end of the left guide rod with the left side face of the circular electromagnetic chuck on the left side. The left block compresses the left compression spring. The right end of the left guide rod presses against the left trigger piece, causing the left trigger piece to rotate to the right and tightly press against the left sensor probe. The left sensor probe transmits the pressure signal to the front contact travel switch. The front contact travel switch sends a signal to the servo control system, indicating that the left cylinder sensor senses the cylinder. Then, the servo control system controls the servo motor to start. The servo motor drives the nut pair to move reversely to the right limit position through the lead screw, moving the rectangular box seat to the right limit position. The circular electromagnetic chuck on the left side sucks the cylinders on the left shelf onto each cylinder bracket. The test piece moves reversely to the right limit switch sensor and contacts it. The servo control system receives the signal from the right limit switch sensor and controls the servo motor to stop, completing the work of taking cylinders from the left shelf;

[0019] When taking cylinders from the right shelf, the working principle is the same as that of taking cylinders from the left shelf:

[0020] Under the control of the servo control system, the stacker moves to the target storage location on the right shelf. The rightmost cylinder bracket is aligned with the left end of the target storage location. The servo control system controls the energization and magnetization of the circular electromagnetic chuck on the right. At the same time, it controls the start of the servo motor. The servo motor drives the rectangular box seat to move from the origin position to the right limit position through the lead screw and nut pair. The test piece moves to the right limit switch sensor and contacts it. The servo control system receives the signal from the right limit switch sensor and controls the servo motor to stop. The circular electromagnetic chuck on the right sucks tightly the bottom of the cylinder. The bottom of the cylinder presses against the right stop block. The right guide rod moves leftward relative to the right guide sleeve, aligning the right end of the right guide rod with the right side of the circular electromagnetic chuck on the right. The right stop block compresses the right compression spring. The left end of the right guide rod presses against the right trigger piece, causing the right trigger piece to rotate leftward and tightly press against the right sensor probe. The right sensor probe transmits the pressure signal to the rear contact travel switch. The rear contact travel switch sends a signal to the servo control system, indicating that the right cylinder sensor has sensed the cylinder. Then, the servo control system controls the servo motor to start. The servo motor drives the nut pair to move reversely to the left limit position through the lead screw, moving the rectangular box seat to the left limit position. The circular electromagnetic chuck on the right sucks the cylinders on the right shelf onto each cylinder bracket. The test piece moves reversely to the left limit switch sensor and contacts it. The servo control system receives the signal from the left limit switch sensor and controls the servo motor to stop, completing the operation of taking cylinders from the right shelf.

[0037] (1) When storing the cylinder 40 on the left shelf:

[0038] The gas cylinder 40 is pre-placed on each gas cylinder bracket. The bottom of the gas cylinder 40 is on the right side, and the suction mechanism is at the right limit position. The test piece 19 contacts the right limit switch sensor 9. The servo control system controls the left circular electromagnetic chuck 11 to be energized and magnetized. The left circular electromagnetic chuck 11 sucks the bottom of the gas cylinder 40. The bottom of the gas cylinder 40 presses against the left stop block 30. The left guide rod 28 moves to the right relative to the left guide sleeve 27, so that the left end of the left guide rod 28 aligns with the left side face of the left circular electromagnetic chuck 11. The left stop block 30 compresses the left pressing spring 31. The right end of the left guide rod 28 presses against the left trigger piece 29, causing the left trigger piece 29 to rotate to the right and tightly press against the left sensor probe 33. The left sensor probe 33 transmits the pressure signal to the front contact travel switch 26. The front contact travel switch 26 sends a signal to the servo control system, indicating that the left gas cylinder sensor senses the gas cylinder 40. Then, the stacker moves under the control of the servo control system and transports the gas cylinder 40 to the target storage location on the left shelf. The leftmost gas cylinder bracket is aligned with the right end of the target storage location left and right. Then, the servo control system controls the servo motor to start. The servo motor drives the nut pair 21 to move to the left through the lead screw 20. The nut pair 21 drives the rectangular box seat 10 to move to the left to the left limit position through the double-ear plate support 14. The left circular electromagnetic chuck 11 then pushes the gas cylinder 40 into the target storage location on the left shelf. The test piece 19 moves to the left limit switch sensor 7 and contacts the left limit switch sensor 7. The servo control system receives the signal from the left limit switch sensor 7 and controls the servo motor to stop. At the same time, it controls the left circular electromagnetic chuck 11 to be de-energized and demagnetized to release the gas cylinder 40. Then, the servo control system controls the servo motor to start. The servo motor drives the nut pair 21 to move in the reverse direction to the origin position through the lead screw 20, so that the rectangular box seat 10 moves to the origin position. The test piece 19 moves to the origin switch sensor 8 and contacts the origin switch sensor 8.
